     On March 26, 2001, LSI Logic entered into a merger agreement with C-Cube,
providing for LSI Logic or a subsidiary of LSI Logic to acquire all of the
outstanding shares of C-Cube common stock by means of an exchange offer and a
subsequent merger. C-Cube's board of directors unanimously approved the merger
agreement, determined that the exchange offer and the merger are fair to, and in
the best interests of, C-Cube stockholders and recommends that C-Cube
stockholders accept the exchange offer and tender their shares pursuant to the
exchange offer.

     LSI Logic, through its wholly owned subsidiary Clover Acquisition Corp., is
offering to exchange 0.79 of a share of LSI Logic common stock for each
outstanding share of C-Cube common stock that is validly tendered and not
properly withdrawn. If completed, the exchange offer will be followed by a
merger of Clover Acquisition Corp. into C-Cube in which shares of C-Cube common
stock will be converted into shares of LSI Logic common stock at the same
exchange ratio used in the exchange offer. After completion of the merger,
C-Cube will be a wholly owned subsidiary of LSI Logic.

     LSI Logic's obligation to exchange its common stock for C-Cube common stock
in the exchange offer is subject to the conditions listed in the section
entitled "Certain Terms of the Merger Agreement -- Conditions to the Exchange
Offer." LSI Logic common stock is listed on The New York Stock Exchange under
the symbol "LSI" and C-Cube common stock is listed on the Nasdaq National Market
under the symbol "CUBE."

FACTORS THAT YOU SHOULD CONSIDER IN CONNECTION WITH THE EXCHANGE OFFER.

     LSI LOGIC IS NOT ASKING YOU FOR A PROXY NOR SHOULD YOU SEND LSI LOGIC A

              QUESTIONS AND ANSWERS ABOUT THE PROPOSED TRANSACTION

Q: WHAT ARE LSI LOGIC AND C-CUBE PROPOSING?

     A: LSI Logic and C-Cube have entered into a merger agreement, pursuant to
which LSI Logic is offering to exchange shares of LSI Logic common stock for all
of the outstanding shares of C-Cube common stock. If the exchange offer is
completed, Clover Acquisition Corp., a wholly owned subsidiary of LSI Logic,
will merge with C-Cube. As a result of the exchange offer and the merger, C-Cube
will become a wholly owned subsidiary of LSI Logic.

Q: WHAT WOULD I RECEIVE IN EXCHANGE FOR MY SHARES OF C-CUBE COMMON STOCK?

     A: In the exchange offer, LSI Logic is offering to exchange 0.79 of a share
of its common stock for each outstanding share of C-Cube common stock that is
validly tendered and not properly withdrawn.

     After completion of the exchange offer, each share of C-Cube common stock
that has not been tendered and accepted for exchange in the exchange offer would
be converted in the merger into 0.79 of a share of LSI Logic common stock, which
is the same fraction of a share of LSI Logic common stock being issued in
exchange for each share of C-Cube common stock accepted for exchange in the
exchange offer.

     LSI Logic will not issue any fractional shares of common stock in
connection with the exchange offer or the merger. C-Cube stockholders will
instead receive cash for any fractional shares otherwise issuable to them.

Q: IS THE EXCHANGE OFFER BEING MADE BY LSI LOGIC OR CLOVER ACQUISITION CORP.?

     A: The exchange offer is technically being made by Clover Acquisition
Corp., which was formed by LSI Logic specifically for the purpose of making the
exchange offer and otherwise facilitating the transaction. Because Clover
Acquisition Corp. is a wholly owned transitory subsidiary of LSI Logic, all of
the shares of C-Cube common stock acquired by Clover Acquisition Corp. in the
exchange offer will actually be beneficially owned and controlled by LSI Logic.
Therefore, although Clover Acquisition Corp. is technically making the exchange
offer and will be a party to the merger, when we discuss the exchange offer and
the merger, we generally refer only to LSI Logic.

Q: HOW LONG WILL IT TAKE TO COMPLETE THE EXCHANGE OFFER AND THE MERGER?

     A: LSI Logic hopes to complete the exchange offer in the second quarter of
2001. LSI Logic expects to complete the merger shortly after it completes the
exchange offer, or, if stockholder approval for the merger is required, shortly
after the special meeting of C-Cube stockholders to approve the merger.

Q: DO I HAVE TO PAY ANY BROKERAGE FEES OR COMMISSIONS?

     A: If you are the record owner of your shares and you tender your shares in
the exchange offer, you will not incur any brokerage fees or commissions. If you
own your shares through a broker or other nominee who tenders the shares on your
behalf, your broker may charge you a commission for doing so. You should consult
with your broker or nominee to determine whether any charges will apply.

Q: DOES C-CUBE'S BOARD OF DIRECTORS SUPPORT THE EXCHANGE OFFER AND THE MERGER?

     A: Yes. C-Cube's board of directors unanimously supports the exchange offer
and the merger and recommends that you tender your shares of C-Cube common stock
in the exchange offer. Information about the recommendation of C-Cube's board of
directors is described in C-Cube's Solicitation/ Recommendation Statement on
Schedule 14D-9, which is being mailed to you together with this prospectus.

Q: HAVE ANY C-CUBE STOCKHOLDERS AGREED TO TENDER THEIR SHARES?

     A: Yes. All of the directors, one of whom is also an executive officer, of
C-Cube have agreed to tender into the exchange offer shares representing
approximately 3.4% of the common stock of C-Cube outstanding as of April 10,
2001.

Q: WHAT PERCENTAGE OF LSI LOGIC COMMON STOCK WILL C-CUBE STOCKHOLDERS OWN AFTER
   THE MERGER?

     A: If LSI Logic obtains all of the shares of C-Cube common stock pursuant
to the transaction, former stockholders of C-Cube would own approximately 11% of
the shares of common stock of LSI Logic, based upon the number of shares of LSI
Logic common stock and C-Cube common stock outstanding on April 10, 2001, and
not taking into account stock options, warrants or convertible securities of
C-Cube or LSI Logic.

Q: WHAT ARE THE MOST SIGNIFICANT CONDITIONS TO THE EXCHANGE OFFER?

     A: LSI Logic's obligation to accept shares of C-Cube common stock for
exchange in the exchange offer is subject to several conditions, including:

     - a majority of the outstanding shares of C-Cube common stock (including
       for purposes of this calculation, to the extent determined by LSI Logic,
       certain outstanding options and an outstanding warrant to purchase shares
       of C-Cube common stock) having been validly tendered and not properly
       withdrawn, which is referred to in this prospectus as the "minimum tender
       condition";

     - the expiration or termination of the applicable waiting period under the
       Hart-Scott-Rodino Antitrust Improvements Act of 1976 and compliance with
       applicable foreign antitrust laws;

     - the registration statement of which this prospectus is a part having been
       declared effective by the Securities and Exchange Commission; and

     - C-Cube having not materially breached any covenant in the merger
       agreement, or breached its representations and warranties in the merger
       agreement, if its breach of its representations and warranties would have
       a material adverse effect on C-Cube.

     These and other conditions to the exchange offer are discussed in this
prospectus in the section entitled "Certain Terms of the Merger
Agreement -- Conditions to the Exchange Offer" beginning on page 60.

Q: HOW DO I PARTICIPATE IN THE EXCHANGE OFFER?

     A: You are urged to read this entire prospectus carefully, and to consider
how the exchange offer and the merger affect you. Then, if you wish to tender
your shares of C-Cube common stock, you should complete and sign the enclosed
letter of transmittal and return it with your stock certificates to the
designated exchange agent, or, if you hold your shares in "street name" through
a broker, ask your broker to tender your shares. Please read this prospectus
carefully for more information about procedures for tendering your shares, the
timing of the exchange offer, extensions of the exchange offer period and your
rights to withdraw your shares from the exchange offer prior to the expiration
date.

Q: WHAT HAPPENS IF I DO NOT TENDER MY SHARES OF C-CUBE COMMON STOCK?

     A: If, after completion of the exchange offer, LSI Logic owns a majority of
the outstanding shares of C-Cube common stock, it intends to complete a merger
of its wholly owned subsidiary, Clover Acquisition Corp., with C-Cube. Upon
completion of the merger, each share of C-Cube common stock that has not been
tendered and accepted for exchange in the exchange offer will be converted into
the same fraction of a share of LSI Logic common stock being issued in exchange
for each share of C-Cube common stock accepted for exchange in the exchange
offer.

Q: WILL I BE TAXED ON THE LSI LOGIC SHARES I RECEIVE?

     A: Your receipt of shares of LSI Logic common stock in the transaction will
be tax-free for United States federal income tax purposes (except for taxes, if
any, resulting from the receipt of cash instead of fractional shares of LSI
Logic common stock), if (1) the transaction is completed under the current terms
of the merger agreement, (2) the minimum tender condition to the exchange offer
is satisfied, and (3) the merger is completed promptly after the exchange offer.
You are urged to read the information regarding material federal income tax
consequences contained in this prospectus carefully, and to consult with your
tax advisor regarding the consequences of participation in the exchange offer
and/or the merger.

Q: DO THE STATEMENTS ON THE COVER PAGE REGARDING THIS PROSPECTUS BEING SUBJECT
   TO CHANGE AND THE REGISTRATION STATEMENT FILED WITH THE SECURITIES AND
   EXCHANGE COMMISSION NOT YET BEING EFFECTIVE MEAN THAT THE EXCHANGE OFFER HAS
   NOT YET COMMENCED?

     A: No. The exchange offer has commenced and effectiveness of the
registration statement is not necessary for you to tender shares of C-Cube
common stock.

Q: WHERE CAN I FIND MORE INFORMATION ABOUT LSI LOGIC AND C-CUBE?

     A: You can find more information about LSI Logic and C-Cube as described in
the section entitled "Where You Can Find More Information," on page 102 of this

THE TRANSACTION (PAGE 30)

     LSI Logic and C-Cube are proposing a two part business combination
transaction, in which LSI Logic intends to acquire all of the outstanding shares
of C-Cube common stock. In the exchange offer, LSI Logic is offering to exchange
0.79 of a share of LSI Logic common stock for each share of C-Cube common stock
that is validly tendered and not properly withdrawn. The initial expiration date
for the exchange offer is May 10, 2001, but, under certain circumstances, LSI
Logic may extend the exchange offer beyond this date.

     Promptly after completion of the exchange offer, LSI Logic intends to merge
its wholly owned subsidiary, Clover Acquisition Corp., with C-Cube. Each share
of C-Cube common stock which has not been tendered and accepted for exchange in
the exchange offer would be converted in the merger into 0.79 of a share of LSI
Logic common stock, which is the same fraction of a share of LSI Logic common
stock being issued in exchange for each share of C-Cube common stock accepted
for exchange in the exchange offer. LSI Logic seeks to acquire ownership of 100%
of the outstanding shares of C-Cube common stock through the exchange offer and
the merger. The exchange offer and the merger are sometimes collectively
referred to in this prospectus as the "transaction."

                                        5
   11

     LSI Logic will not issue any fractional shares of common stock in
connection with the exchange offer or the merger. C-Cube stockholders will
instead receive cash for any fractional shares otherwise issuable to them.

     Example:

     - If you currently own 10 shares of C-Cube common stock and if you tender
       these shares in the exchange offer, after the exchange offer you will
       receive seven shares of LSI Logic common stock and a check for the value
       of 90% of a share of LSI Logic common stock, rounded up to the nearest
       whole cent.

     - On April 11, 2001, the most recent practicable date prior to the mailing
       of this prospectus, the last sale price of LSI Logic common stock on The
       New York Stock Exchange was $17.71. Applying the 0.79 exchange ratio to
       the LSI Logic closing price on that date, each holder of shares of C-Cube
       common stock would be entitled to receive shares of LSI Logic common
       stock with a market value of approximately $13.99 for each share of
       C-Cube common stock. The actual value of the LSI Logic common stock to be
       issued in the exchange offer and the merger, however, will depend on the
       market price of LSI common stock at the completion of the exchange offer
       and the merger, and may be more or less than the value given in this
       example. We urge you to obtain current price quotations for C-Cube and
       LSI Logic common stock prior to making your decision whether to tender
       into the exchange offer.

MARKET PRICE AND DIVIDEND INFORMATION (PAGE 11)

     LSI Logic common stock is listed on The New York Stock Exchange under the
symbol "LSI" and C-Cube common stock is listed on the Nasdaq National Market
under the symbol "CUBE." On March 23, 2001, the last full trading day before the
public announcement of the exchange offer and the merger, the last sale price
per share of LSI Logic common stock on The New York Stock Exchange was $20.69
and the last sale price per share of C-Cube common stock on the Nasdaq National
market was $8.81. On April 11, 2001, the most recent practicable date prior to
the mailing of this prospectus, the last sale price per share of LSI Logic
common stock on The New York Stock Exchange was $17.71 and the last sale price
per share of C-Cube common stock on the Nasdaq National Market was $13.74.

MATERIAL FEDERAL INCOME TAX CONSEQUENCES (PAGE 43)

     LSI Logic and C-Cube believe that the transaction will qualify as a
tax-free reorganization for United States federal income tax purposes, if: (1)
the transaction is completed under the current terms of the merger agreement;
(2) the minimum tender condition to the exchange offer is satisfied; and (3) the
merger is completed promptly after the exchange offer. Based on these
assumptions, your receipt of LSI Logic common stock in the transaction will be
tax-free for United States federal income tax purposes (except for taxes, if
any, resulting from the receipt of cash instead of fractional shares of LSI
Logic common stock).

     The above described tax treatment of the exchange offer and the merger to
C-Cube stockholders depends on, among other things, some facts that will not be
known before the completion of the merger. C-Cube stockholders are urged to
carefully read the discussion in the section entitled "The Transaction --
Material Federal Income Tax Consequences" beginning on page 43 of this
prospectus. That discussion includes a summary of the United Stated federal
income tax consequences of participation in the exchange offer and the merger in
the event that the assumptions described above are not satisfied.

     TAX MATTERS CAN BE COMPLICATED, AND THE TAX CONSEQUENCES OF THE EXCHANGE
OFFER AND THE MERGER TO YOU WILL DEPEND ON THE FACTS OF YOUR OWN SITUATION. YOU
SHOULD CONSULT YOUR OWN TAX ADVISOR TO FULLY UNDERSTAND THE TAX CONSEQUENCES OF
THE EXCHANGE OFFER AND THE MERGER TO YOU.

REASONS FOR THE TRANSACTION

     C-CUBE (PAGE 38). C-Cube's board of directors believes that the transaction
could result in a number of benefits to C-Cube and its stockholders. C-Cube's
reasons for entering into the transaction and a number of factors considered by
C-Cube's board of directors in determining whether to enter into the transaction
are described below.

     LSI LOGIC (PAGE 40). LSI Logic's board of directors believes that the
transaction represents a compelling opportunity to enhance value for both LSI
Logic and C-Cube stockholders. LSI Logic's reasons for entering into the
transaction and a number of factors considered by LSI Logic's board of directors
in determining whether to enter into the transaction are described below.

RECOMMENDATION TO C-CUBE STOCKHOLDERS

     C-Cube's board of directors has unanimously approved the merger agreement,
determined that the exchange offer and the merger are fair to, and in the best
interests of, C-Cube stockholders and recommends that C-Cube stockholders accept
the exchange offer and tender their shares pursuant to the exchange offer.
Information about the recommendation of C-Cube's board of directors is more
fully described in C-Cube's Solicitation/Recommendation Statement on Schedule
14D-9, which is being mailed to you together with this prospectus.

OPINION OF C-CUBE'S FINANCIAL ADVISOR

     C-Cube has received a written opinion, dated March 26, 2001, from Credit
Suisse First Boston, to the effect that, as of the date of the opinion and based
on and subject to the matters described in its opinion, the exchange ratio
provided for in the transaction was fair, from a financial point of view, to the
holders of C-Cube common stock (other than LSI Logic and its affiliates). CREDIT
SUISSE FIRST BOSTON'S OPINION IS ADDRESSED TO THE C-CUBE BOARD OF DIRECTORS AND
DOES NOT CONSTITUTE A RECOMMENDATION TO ANY STOCKHOLDER REGARDING WHETHER
STOCKHOLDERS SHOULD TENDER SHARES PURSUANT TO THE EXCHANGE OFFER, OR HOW
STOCKHOLDERS SHOULD VOTE OR ACT ON ANY MATTER RELATING TO THE MERGER.

TIMING OF THE EXCHANGE OFFER (PAGE 30)

     The exchange offer commenced on the date of this prospectus and is
currently scheduled to expire on May 10, 2001. However, if any condition to the
exchange offer is not satisfied, or, where permissible, waived, LSI Logic is
obligated, under the terms of the merger agreement, to extend the exchange offer
until all of the conditions have been satisfied or, where permissible, waived,
or until the merger agreement is terminated in accordance with its terms.

EXTENSION; TERMINATION AND AMENDMENT (PAGE 30)

     Subject to the terms of the merger agreement, LSI Logic has agreed to
extend the exchange offer for successive extension periods not in excess of 10
business days per extension if, at the scheduled expiration date of the exchange
offer, any of the conditions to the exchange offer has not been satisfied or,
where permissible, waived. In addition, LSI Logic is entitled to extend the
exchange offer if required by the rules of the Securities and Exchange
Commission or The New York Stock Exchange. During an extension, all shares of
C-Cube common stock previously tendered and not properly withdrawn will remain
subject to the exchange offer, subject to your right to withdraw your shares of
C-Cube common stock. An extension of the exchange offer is different than a
subsequent offering period. The consequences of a subsequent offering period are
described below.

                                        7
   13

     LSI Logic reserves the right to make any changes in the terms and
conditions of the exchange offer by giving oral or written notice of the changes
to the Exchange Agent and by making a public announcement thereof; however,
without the prior written consent of C-Cube, LSI Logic cannot:

     - decrease the number of shares of C-Cube common stock sought in the
       exchange offer;

     - make any changes to the form or amount of consideration to be issued or
       paid in exchange for shares of C-Cube common stock in the exchange offer;

     - impose any additional conditions on the exchange offer other than those
       already described in the merger agreement;

     - amend or waive the minimum tender condition or other specified conditions
       as described in the merger agreement;

     - extend the expiration date of the exchange offer, except in the
       circumstances described in the merger agreement; or

     - make any other change to the terms and conditions of the exchange offer
       which is adverse to the holders of shares of C-Cube common stock.

     LSI Logic is required to follow any extension, termination, amendment or
delay, as promptly as practicable, with a public announcement. Any announcement
about an extension is required to be issued no later than 9:00 a.m., New York
time, on the next business day after the previously scheduled expiration date of
the exchange offer. Subject to applicable law, including Rules 14d-4(d) and
14d-6(c) under the Securities Exchange Act of 1934, which require that any
material change in the information published, sent or given to stockholders in
connection with the exchange offer be promptly sent to stockholders in a manner
reasonably designed to inform stockholders of the change, and without limiting
the manner in which LSI Logic may choose to make any public announcement, LSI
Logic assumes no obligation to publish, advertise or otherwise communicate the
public announcement other than by making a release to the Dow Jones News
Service.

SUBSEQUENT OFFERING PERIOD (PAGE 31)

     LSI Logic may elect to provide a subsequent offering period of three to 20
business days after the acceptance of shares of C-Cube common stock in the
exchange offer if the requirements of Rule 14d-11 under the Securities Exchange
Act of 1934 have been met. You will not have the right to withdraw any shares of
C-Cube common stock that you tender during the subsequent offering period. LSI
is required to accept for exchange, and to deliver shares of LSI Logic common
stock in exchange for, shares of C-Cube common stock that are validly tendered
promptly after they are tendered during any subsequent offering period. If LSI
Logic elects to provide a subsequent offering period, it is required to make a
public announcement to that effect no later than 9:00 a.m., New York time, on
the next business day after the previously scheduled expiration date of the
exchange offer.

WITHDRAWAL RIGHTS (PAGE 32)

     Your tender of shares of C-Cube common stock pursuant to the exchange offer
is irrevocable, except that, other than during any subsequent offering period,
shares of C-Cube common stock tendered pursuant to the exchange offer may be
withdrawn at any time prior to the expiration date of the exchange offer, as it
may be extended, and unless LSI Logic previously accepted them for exchange
pursuant to the exchange offer, may also be withdrawn at any time after June 11,
2001.

     If LSI Logic elects to provide a subsequent offering period pursuant to
Rule 14d-11 under the Securities Exchange Act of 1934, you will not have the
right to withdraw shares of C-Cube common stock that you tender in the
subsequent offering period.

EXCHANGE OF SHARES OF C-CUBE COMMON STOCK; DELIVERY OF SHARES OF LSI LOGIC
COMMON STOCK (PAGE 31)

     Upon the terms of, and subject to the conditions to, the exchange offer,
including, if the exchange offer is extended or amended, the terms and
conditions of any extension or amendment, LSI Logic is required to accept for
exchange, and to deliver shares of LSI Logic common in exchange for, shares of
C-Cube common stock validly tendered and not properly withdrawn, promptly after
the expiration date of the exchange offer and promptly after they are tendered
during any subsequent offering period.

PROCEDURE FOR TENDERING (PAGE 33)

     For you to validly tender shares of C-Cube common stock pursuant to the
exchange offer, a properly completed and duly executed letter of transmittal or
manually executed facsimile of that document, along with any required signature
guarantees, or an agent's message in connection with a book-entry transfer, and
any other required documents, must be transmitted to and received by LSI Logic's
Exchange Agent at the address on the back cover of this prospectus. In addition,
certificates for tendered shares of C-Cube common stock must be received by the
Exchange Agent at that address, or the shares of C-Cube common stock must be
tendered pursuant to the procedures for book-entry tender, in each case before
the expiration date of the exchange offer.

A STOCKHOLDER VOTE MAY BE REQUIRED TO APPROVE THE MERGER (PAGE 47)

     If, after completion of the exchange offer, as it may be extended and
including any subsequent offering period, LSI Logic owns 90% or more of the
outstanding shares of C-Cube common stock, the merger can be accomplished
without a vote of C-Cube stockholders. If, on the other hand, after completion
of the exchange offer, as it may be extended and including any subsequent
offering period, LSI Logic owns more than 50% but less than 90% of the
outstanding shares of C-Cube common stock, a meeting of C-Cube stockholders and
the affirmative vote of at least a majority of the shares of C-Cube common stock
outstanding on the record date for such meeting will be needed to complete the
merger. Since LSI Logic will own a majority of the shares of C-Cube common stock
outstanding on the record date, approval of the merger by C-Cube stockholders
will be assured.

THE STOCKHOLDER AGREEMENTS (PAGE 67)

     As of the date of the merger agreement, all of the directors, one of whom
is also an executive officer, of C-Cube, have agreed to tender an aggregate
1,735,765 shares of C-Cube common stock representing approximately 3.4% of the
shares of C-Cube common stock outstanding as of April 10, 2001.

INTERESTS OF C-CUBE'S OFFICERS AND DIRECTORS IN THE TRANSACTION (PAGE 42)

     When you consider C-Cube's board of directors' recommendation that C-Cube
stockholders tender their shares in the exchange offer, you should be aware that
some C-Cube officers and directors may have interests in the transaction that
may be different from, or in addition to, yours. See the section entitled "The
Transaction -- Interests of C-Cube Officers and Directors in the Transaction" on
page 42, as well as C-Cube's Solicitation/Recommendation Statement on Schedule
14D-9, which is being mailed to you together with this prospectus.

CONDITIONS TO THE EXCHANGE OFFER AND THE MERGER (PAGES 60 AND 62)

     The obligation of LSI Logic to accept shares of C-Cube common stock for
exchange in the exchange offer and the obligations of LSI Logic and C-Cube to
complete the merger are subject to the satisfaction of a number of conditions,
which may, in some instances, be waived.

LIMITATION ON C-CUBE'S ABILITY TO CONSIDER OTHER ACQUISITION PROPOSALS (PAGE 57)

     C-Cube has agreed not to solicit, initiate, encourage or discuss any
proposal for a business combination or other similar transaction involving the
acquisition or purchase of 15% or more of any class of equity securities of
C-Cube or 15% or more of the book or market value of C-Cube's assets from or
with any party other than LSI Logic prior to completion of the merger unless the
other party has made an unsolicited written proposal to C-Cube's board of
directors for a transaction which C-Cube's board of directors believes in good
faith, after consultation with C-Cube's financial advisor, is or could
reasonably be expected to be a superior proposal, according to the terms of the
merger agreement, and a number of other conditions are satisfied.

TERMINATION OF THE MERGER AGREEMENT (PAGE 63)

     LSI Logic and C-Cube can terminate the merger agreement under certain
circumstances.

TERMINATION FEE (PAGE 65)

     The merger agreement requires C-Cube to pay LSI Logic a termination fee
equal to $33 million in cash if the merger agreement is terminated under certain
circumstances.

ACCOUNTING TREATMENT (PAGE 46)

     LSI Logic will account for the merger as a purchase for financial reporting
purposes.

APPRAISAL RIGHTS (PAGE 47)

     C-Cube stockholders are not entitled to appraisal rights in connection with
the exchange offer. If, after completion of the exchange offer, as it may be
extended and including any subsequent offering period, LSI Logic owns a majority
but less than 90% of the outstanding shares of C-Cube common stock, LSI Logic
has agreed to effect a long-form merger as permitted under Delaware law, which
would require notice to and approval of C-Cube stockholders. C-Cube stockholders
who have not exchanged their shares of C-Cube common stock in the exchange offer
would not have appraisal rights in connection with a long-form merger.

     If, however, after completion of the exchange offer, as it may be extended
and including any subsequent offering period, LSI Logic owns 90% or more of the
outstanding shares of C-Cube common stock, LSI Logic has agreed to effect a
short-form merger as permitted under Delaware law. In the event that LSI Logic
completes the transaction through a short-form merger, stockholders who did not
tender, or who tendered and withdrew, their shares of C-Cube common stock in the
exchange offer would have the right under Delaware law to demand appraisal of
their shares of C-Cube common stock, but only if they comply with certain
statutory requirements. Stockholders who comply with the applicable statutory
procedures will be entitled to receive a judicial determination of the fair
value of their shares of C-Cube common stock and to receive payment of this fair
value in cash. In the event of a short-form merger, information regarding these
requirements will be provided to C-Cube stockholders who have not exchanged
their shares of C-Cube common stock in the exchange offer.

REGULATORY APPROVALS (PAGE 46)

     Completion of the exchange offer is subject to compliance with the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, also referred to as the
"HSR Act," and a limited number of foreign antitrust regulations. The
notifications required under the HSR Act to the Federal Trade Commission and the
Antitrust Division of the Department of Justice were filed on April 10, 2001 and

     The following table sets forth the last sale prices per share of LSI Logic
common stock on The New York Stock Exchange and C-Cube common stock on the
Nasdaq National Market on March 23, 2001, the last trading day prior to the
public announcement of the proposed transaction, and on April 11, 2001, the most
recent date for which prices were practically available prior to the mailing of
this prospectus. The table also sets forth the value of the fraction of a share
of LSI Logic common stock that a C-Cube stockholder would have received for one
share of C-Cube common stock, assuming that the transaction had taken place on
those dates. These values have been calculated by multiplying 0.79, the fraction
of a share of LSI Logic common stock to be exchanged for each share of C-Cube
common stock, by the last sale price per share of LSI Logic common stock on
those dates. The actual value of the shares of LSI Logic common stock that a
C-Cube stockholder would receive in the exchange offer and the merger may be
higher or lower than the prices listed below.

     On January 25, 2000, LSI Logic announced a two-for-one stock split, which
was declared by LSI Logic's board of directors as a 100% stock dividend payable
to stockholders of record on February 4, 2000, as one new share of LSI Logic
common stock for each share of LSI Logic common stock held on that date. The
newly issued shares of LSI Logic common stock were distributed on February 16,
2000. In the table above, earnings per share amounts have been restated to give
retroactive recognition to the two-for-one stock split.

     During 2000, LSI Logic recorded amortization of non-cash deferred stock
compensation of $41 million as a result of the adoption of FASB interpretation
No. 44, "Accounting for Certain Transactions Involving Stock Compensation" which
became effective July 1, 2000. LSI Logic's acquisitions of DataPath Systems,
Inc. and Syntax Systems, Inc. closed on July 14, 2000 and November 29, 2000,
respectively, after the adoption of the new interpretation. During 2000, LSI
Logic recorded a $77 million in-process research and development charge
associated with the acquisitions of ParaVoice, DataPath, Intraserver and the
purchases of divisions of NeoMagic and Cacheware.

     On June 22, 1999, LSI Logic combined with SEEQ Technology, Inc., also known
as "SEEQ," in a transaction accounted for as a pooling of interests. All
financial information has been restated retroactively to reflect the combined
operations of LSI Logic and SEEQ as if the combination had occurred at the
beginning of the earliest period presented. Prior to the combination, SEEQ's
fiscal year-end was the last Sunday in September of each year, whereas LSI Logic
operates on a year ending December 31. SEEQ's financial information has been
recast to conform to LSI Logic's year-end.

     During 1999, LSI Logic expensed an unamortized preproduction balance of $92
million, net of taxes, associated with the manufacturing facility in Gresham,
Oregon and has presented it as a cumulative effect of a change in accounting
principle in accordance with SOP No. 98-5, "Reporting on the Costs of Start-up
Activities."

     On August 6, 1998, LSI Logic completed the acquisition of all of the
outstanding capital stock of Symbios. The transaction was accounted for as a
purchase, and accordingly, the results of operations of Symbios and estimated
fair value of assets acquired and liabilities assumed were included in LSI
Logic's consolidated financial statements as of August 6, 1998, the effective
date of the purchase, through the end of the period. During 1998, LSI Logic
reported a charge for restructuring of $75 million and in-process research and
development costs of $146 million related to the acquisition of Symbios on
August 6, 1998.

     On November 21, 1997, the Emerging Issues Task Force ("EITF") issued EITF
97-13, "Accounting for Costs Incurred in Connection with a Consulting Contract
or an Internal Project that Combines Business Process Re-engineering and
Information Technology Transformation." EITF 97-13 required that LSI Logic
expense, in 1997, all costs previously capitalized in connection with business
process re-engineering activities as defined by the statement. Accordingly, LSI
Logic recorded a charge of $1.4 million, net of related tax of $0.6 million,
during the fourth quarter of 1997.

                           COMPARATIVE PER SHARE DATA

     The following table reflects (a) the historical net income and book value
per share of LSI Logic common stock and the historical income from continuing
operations and book value per share of C-Cube common stock in comparison with
the unaudited pro forma income from continuing operations and book value per
share after giving effect to the proposed transaction, and (b) the equivalent
historical income from continuing operations and book value per share
attributable to 0.79 of a share of LSI Logic common stock which will be received
for each share of C-Cube common stock validly tendered and not properly
withdrawn in the exchange offer.

     The historical book value per share is computed by dividing common
stockholders' equity as of December 31, 2000 by the actual number of shares of
common stock outstanding. The pro forma income per share from continuing
operations is computed by dividing the pro forma income from continuing
operations by the pro forma weighted average number of shares outstanding,
assuming LSI Logic had merged with C-Cube at the beginning of the earliest
period presented. The pro forma combined book value per share is computed by
dividing total pro forma stockholders' equity by the pro forma number of shares
of common stock outstanding at December 31, 2000, assuming the merger had
occurred on that date. The C-Cube equivalent pro forma combined per share
amounts are calculated by multiplying the LSI Logic pro forma combined per share
amounts by the exchange ratio of 0.79.

     The following information should be read in conjunction with (a) the
separate historical financial statements and related notes of LSI Logic
incorporated by reference in this prospectus, (b) the separate historical
financial statements and related notes of C-Cube included in this prospectus,
and (c) the unaudited pro forma combined condensed financial information and
related notes of LSI Logic and the selected historical and selected unaudited
pro forma financial data included elsewhere in this prospectus. The pro forma
information is presented for illustrative purposes only and is not necessarily
indicative of the operating results or financial position that would have
occurred if the merger had been completed as of the assumed dates, nor is it
necessarily indicative of the future operating results or financial position of
the combined companies.

     Neither LSI Logic nor C-Cube have paid any cash dividends during the
periods presented.

                                  RISK FACTORS

     You should consider the following matters in deciding whether to tender
your shares of C-Cube common stock in the exchange offer. You should consider
these matters in connection with the other information that LSI Logic has
included or incorporated by reference into this prospectus.

RISKS RELATED TO THE TRANSACTION

THE SHARES OF LSI LOGIC COMMON STOCK TO BE RECEIVED BY C-CUBE STOCKHOLDERS IN
THE TRANSACTION WILL FLUCTUATE IN VALUE.

     C-Cube stockholders will receive a fixed number of shares of LSI Logic
common stock in the transaction, not a fixed value.

     In the transaction, each share of C-Cube common stock will be converted
into 0.79 of a share of LSI Logic common stock. As the exchange ratio is fixed,
the number of shares that C-Cube stockholders will receive in the transaction
will not change, even if the market price of LSI Logic common stock changes.
There will be no adjustment to the exchange ratio or right to terminate the
merger agreement, the exchange offer or the merger based solely on fluctuations
in the price of LSI Logic common stock. In recent years, and particularly in
recent months, the stock market in general, and the securities of technology
companies in particular, have experienced extreme price and volume fluctuations.
These market fluctuations may adversely affect the market price of LSI Logic
common stock. The market price of LSI Logic common stock upon and after
completion of the exchange offer or the merger could be lower than the market
price on the date of the merger agreement or the current market price. You
should obtain recent market quotations of LSI Logic common stock before you
tender your shares.

     On April 11, 2001, the most recent practicable date prior to the mailing of
this prospectus for which stock price information was available, the last sale
price of a share of LSI Logic common stock on The New York Stock Exchange was
$17.71. On the basis of this price, the hypothetical value of the consideration
to be received for each share of C-Cube common stock in the exchange offer and
in the merger would be $13.99. The actual market value of the consideration to
be received by you for each C-Cube share you surrender as of the closing of the
exchange offer or the merger could be materially more or less than the value
given in this example, depending on the market price of LSI Logic common stock
at that time.

FAILURE TO RETAIN KEY EMPLOYEES COULD DIMINISH THE BENEFITS OF THE TRANSACTION.

     The successful combination of LSI Logic and C-Cube will depend in part on
the retention of key personnel. There can be no assurance that LSI Logic will be
able to retain C-Cube's key management, technical, administrative, marketing,
sales and customer support personnel, or that LSI Logic will realize the
anticipated benefits of the transaction.

IF LSI LOGIC AND C-CUBE ARE NOT SUCCESSFUL IN INTEGRATING THEIR ORGANIZATIONS,
THEY WILL NOT BE ABLE TO OPERATE EFFICIENTLY AFTER THE TRANSACTION.

     Achieving the benefits of the transaction will depend in part on the
successful integration of LSI Logic's and C-Cube's operations and personnel in a
timely and efficient manner. Such integration will be a complex process and will
require coordination of different development and engineering teams, sales and
marketing personnel, information and software systems and service organizations.
This will be difficult and unpredictable because of possible cultural conflicts
and different opinions on how best to run these operations. If LSI Logic and
C-Cube cannot successfully integrate their operations and personnel, they may
not realize the expected benefits of the transaction.

     In addition, after the merger, LSI Logic intends to develop new products
and services that combine C-Cube's assets with LSI Logic's assets. This may
result in longer sales cycles and product implementations, which may cause
revenue and operating income to fluctuate and fail to meet expectations. To
date, LSI Logic has not completed its investigation into the
challenges -- technological, market-driven or otherwise -- to developing and
marketing these new products and services in a timely and

                                        19
   25

efficient way. There can be no assurance that LSI Logic and C-Cube will be able
to overcome these challenges, or that a market for such new products and
services will develop after the merger.

INTEGRATING THE COMPANIES MAY DIVERT MANAGEMENT'S ATTENTION AWAY FROM OPERATIONS
AND MAY RESULT IN SUBSTANTIAL COSTS.

     Successful integration of LSI Logic's and C-Cube's operations, products and
personnel may place a significant burden on management and internal resources of
the companies. The diversion of management attention and any difficulties
encountered in the transition and integration process could harm the combined
company's business, financial condition and operating results.

     LSI Logic may incur significant costs to integrate the companies into a
single business. LSI Logic expects to incur costs for integrating C-Cube's
operations, products and personnel. These costs may be substantial and may
include costs for:

     - employee redeployment, relocation or severance;

     - conversion of information systems;

     - combining teams and processes in various functional areas; and

     - reorganization or closures of facilities.

THE RECEIPT OF SHARES OF LSI LOGIC COMMON STOCK COULD BE TAXABLE TO YOU,
DEPENDING ON FACTS SURROUNDING THE TRANSACTION.

     LSI Logic and C-Cube have structured the transaction to qualify as a
tax-free reorganization for federal income tax purposes. As a condition to the
completion of the exchange offer, LSI Logic and C-Cube are required to obtain
opinions of Cooley Godward LLP and Wilson Sonsini Goodrich & Rosati,
Professional Corporation, respectively, that, although there is limited
authority, the transaction will be treated for federal income tax purposes as a
reorganization within the meaning of Section 368(a) of the Internal Revenue Code
of 1986, also referred to as the "Code," if: (1) the transaction is completed
under the current terms of the merger agreement; (2) the minimum tender
condition for the exchange offer is satisfied; and (3) the merger is completed
promptly after the exchange offer. However, the ability to satisfy these factual
assumptions, and therefore the federal income tax consequences of the
transaction, depends in part on facts that will not be available before the
completion of the transaction. If these factual assumptions are not satisfied, a
C-Cube stockholder's exchange of shares of C-Cube common stock for shares of LSI
Logic common stock in the exchange offer or the merger could be a taxable
transaction.

PARTNERS OR CUSTOMERS MAY REACT UNFAVORABLY TO THE PROPOSED TRANSACTION.

     Both LSI Logic and C-Cube partner with numerous other technology companies,
including software and services firms, to deliver LSI Logic and C-Cube products
to customers. Some of these partners may feel that the combined company poses
new competitive threats to their businesses and as a result their relationships
with LSI Logic or C-Cube may change in a manner adverse to LSI Logic or C-Cube.
In addition, some of LSI Logic's customers or some of C-Cube's customers may
view the combined company as a competitor and, therefore, cancel orders with LSI
Logic or C-Cube.

C-CUBE'S OFFICERS AND DIRECTORS HAVE POTENTIAL CONFLICTS OF INTEREST IN THE
TRANSACTION.

     C-Cube stockholders should be aware of potential conflicts of interest and
the benefits available to C-Cube officers and directors when considering
C-Cube's board of directors' recommendation to accept the exchange offer and
approve the merger. Certain C-Cube officers and directors have stock options,
retention agreements and/or indemnification rights that provide them with
interests in the transaction that are different from, or in addition to,
interests of C-Cube stockholders. See the section entitled "The
Transaction -- Interests of C-Cube's Officers and Directors in the Transaction"
on page 42.

RISKS RELATED TO LSI LOGIC'S BUSINESS

LSI LOGIC'S PRODUCT AND DEVELOPMENT ACTIVITIES OCCUR IN A HIGHLY COMPETITIVE
ENVIRONMENT.

     The semiconductor and SAN systems segments in which LSI Logic conducts
business are characterized by rapid technological change, short product cycles
and evolving industry standards. LSI Logic believes that its future success
depends, in part, on its ability to improve on existing technologies and to
develop and implement new ones in order to continue to reduce semiconductor chip
size and improve product performance and manufacturing yields. LSI Logic must
also be able to adopt and implement emerging industry standards and to adapt
products and processes to technological changes. If LSI Logic is not able to
implement new process technologies successfully or to achieve volume production
of new products at acceptable yields, its operating results and financial
condition will be adversely impacted.

     In addition, LSI Logic must continue to develop and introduce new products
that compete effectively based on price and performance and that satisfy
customer requirements. LSI Logic continues to emphasize engineering development
and acquisition of CoreWare building blocks and integration of its CoreWare
libraries into its design capabilities. LSI Logic's cores and standard products
are intended to be based upon industry standard functions, interfaces and
protocols so that they are useful in a wide variety of systems applications.
Development of new products and cores often requires long-term forecasting of
market trends, development and implementation of new or changing technologies
and a substantial capital commitment. LSI Logic cannot assure you that cores or
standard products that it selects for investment of its financial and
engineering resources will be developed or acquired in a timely manner or will
enjoy market acceptance.

LSI LOGIC OPERATES HIGHLY COMPLEX AND COSTLY MANUFACTURING FACILITIES.

     The manufacture and introduction of LSI Logic's products is a complicated
process. LSI Logic confronts challenges in the manufacturing process that
require LSI Logic to:

     - maintain a competitive manufacturing cost structure;

     - implement the latest process technologies required to manufacture new
       products;

     - exercise stringent quality control measures to ensure high yields;

     - effectively manage the subcontractors engaged in the test and assembly of
       products; and

     - update equipment and facilities as required for leading edge production
       capabilities.

     LSI Logic does not control the timing or size of orders for its products.
LSI Logic generally does not have long-term volume production contracts with its
customers.

     There is a risk that LSI Logic will be unable to meet sudden increases in
demand beyond its current manufacturing capacity, which may result in additional
capital expenditures and production costs. Meanwhile, order volumes below
anticipated levels may result in the under-utilization of LSI Logic's
manufacturing facilities, resulting in higher per unit costs, which could
adversely affect its operating results and financial condition.

LSI LOGIC'S MANUFACTURING FACILITIES ARE SUBJECT TO DISRUPTION FOR REASONS
BEYOND LSI LOGIC'S CONTROL.

     LSI Logic's newest wafer fabrication site in Gresham, Oregon is a highly
complex, state-of-the-art facility. Anticipated production rates depend upon the
reliable operation and effective integration of a variety of hardware and
software components. There is no assurance that all of these components will be
fully functional or successfully integrated on time or that the facility will
achieve the forecasted yield targets. The capital expenditures required to bring
the facility to full operating capacity may be greater than LSI Logic
anticipates and result in lower margins.

                                        21
   27

     Operations at any of LSI Logic's primary manufacturing facilities, or at
any of its test and assembly subcontractors, may be disrupted for reasons beyond
its control, including work stoppages, fire, earthquake, floods or other natural
disasters. In addition, California is currently experiencing a power shortage,
which may spread to other areas of the country, such as Oregon, where LSI
Logic's newest wafer fabrication facility is located. Such an unexpected
disruption could cause delays in shipments of products to LSI Logic's customers
and alternate sources for production may be unavailable on acceptable terms.
This could result in the cancellation of orders or loss of customers.

LSI LOGIC HAS SIGNIFICANT CAPITAL REQUIREMENTS TO MAINTAIN AND GROW ITS
BUSINESS.

     In order to remain competitive, LSI Logic must continue to make significant
investments in new facilities and capital equipment. During 2001, LSI Logic
anticipates that it will spend approximately $500 million on capital assets and
that it will be required to spend potentially larger amounts thereafter. LSI
Logic may seek additional equity or debt financing from time to time and cannot
be certain that additional financing will be available on favorable terms.
Moreover, any future equity or convertible debt financing will decrease the
percentage of equity ownership of existing stockholders and may result in
dilution, depending on the price at which the equity is sold or the debt is
converted. In addition, the high level of capital expenditures required to
remain competitive results in relatively high fixed costs. If demand for LSI
Logic's products does not absorb additional capacity, the fixed costs and
operating expenses related to increases in its production capacity could have a
material adverse impact on its operating results and financial condition. As of
December 31, 2000, LSI Logic had convertible notes outstanding of approximately
$845 million.

LSI LOGIC IS EXPOSED TO FLUCTUATIONS IN FOREIGN CURRENCY EXCHANGE RATES.

     LSI Logic has international subsidiaries and distributors that operate and
sell its products globally. Further, LSI Logic purchases a substantial portion
of its raw materials and manufacturing equipment from foreign suppliers, and
incurs labor and other operating costs in foreign currencies, particularly in
its Japanese manufacturing facilities. As a result, LSI Logic is exposed to the
risk of changes in foreign currency exchange rates or declining economic
conditions in these countries.

LSI LOGIC DOES BUSINESS IN EUROPE AND FACES RISKS ASSOCIATED WITH THE
EURODOLLAR.

     A new European currency was implemented in January 1999 to replace the
separate currencies of eleven western European countries. This has required
changes in LSI Logic's operations as it modified systems and commercial
arrangements to deal with the new currency. Although a three-year transition
period is expected during which transactions may also be made in the old
currencies, this is requiring dual currency processes for LSI Logic's
operations. LSI Logic has identified issues involved and will continue to
address them. There can be no assurances that all problems will be foreseen and
controlled without any adverse impact on its operating results and financial
condition.

LSI LOGIC PROCURES PARTS AND RAW MATERIALS FROM LIMITED DOMESTIC AND FOREIGN
SOURCES.

     LSI Logic uses a wide range of parts and raw materials in the production of
its semiconductors, host adapter boards and storage systems, including silicon
wafers, processing chemicals and electronic and mechanical components. LSI Logic
does not generally have guaranteed supply arrangements with its suppliers and
does not maintain an extensive inventory of parts and materials for
manufacturing. LSI Logic purchases some of these parts and materials from a
limited number of vendors and some from a single supplier. On occasion, LSI
Logic has experienced difficulty in securing an adequate volume and quality of
parts and materials. There is no assurance that, if LSI Logic has difficulty in
obtaining parts or materials in the future, alternative suppliers will be
available, or that these suppliers will provide parts and materials in a timely
manner or on favorable terms. As a result, LSI Logic may be adversely affected
by delays in new and current product shipments. If LSI Logic cannot obtain
adequate materials for manufacture of its products, there could be a material
adverse impact on its operating results and financial condition.
                                        22
   28

LSI LOGIC OPERATES IN HIGHLY COMPETITIVE MARKETS.

     LSI Logic competes in markets that are intensely competitive, and which
exhibit both rapid technological change and continual price erosion. LSI Logic's
competitors include many large domestic and foreign companies that have
substantially greater financial, technical and management resources than LSI
Logic does. Several major diversified electronics companies offer ASIC products
and/or other standard products that are competitive with LSI Logic's product
lines. Other competitors are specialized, rapidly growing companies that sell
products into the same markets that LSI Logic targets. Some of LSI Logic's large
customers may develop internal design and production capabilities to manufacture
their own products, thereby displacing LSI Logic's products. There is no
assurance that the price and performance of LSI Logic's products will be
superior relative to the products of its competitors. As a result, LSI Logic may
experience a loss of competitive position that could result in lower prices,
fewer customer orders, reduced revenues, reduced gross profit margins and loss
of market share. To remain competitive, LSI Logic continually evaluates its
worldwide operations, looking for additional cost savings and technological
improvements.

     LSI Logic's future competitive performance depends on a number of factors,
including its ability to:

     - properly identify target markets;

     - accurately identify emerging technological trends and demand for product
       features and performance characteristics;

     - develop and maintain competitive products;

     - enhance its products by adding innovative features that differentiate its
       products from those of its competitors;

     - bring products to market on a timely basis at competitive prices;

     - respond effectively to new technological changes or new product
       announcements by others;

     - adapt products and processes to technological changes; and

     - adopt and/or set emerging industry standards.

     LSI Logic may not meet its design, development and introduction schedules
for new products or enhancements to its existing and future products. In
addition, LSI Logic's products may not achieve market acceptance or sell at
favorable prices.

LSI LOGIC CONCENTRATES ITS SALES EFFORTS ON A LIMITED NUMBER OF CUSTOMERS.

     LSI Logic is increasingly dependent on a limited number of customers for a
substantial portion of revenues as a result of its strategy to focus its
marketing and selling efforts on select, large-volume customers. One customer
represented 12% of LSI Logic's total consolidated revenues for the year ended
December 31, 2000. While no customer represented 10% or more of the total
revenue in the semiconductor segment for the year ended December 31, 2000, in
the SAN systems segment, there were three customers with revenues representing
31%, 17% and 13% of total SAN systems revenues.

     LSI Logic's operating results and financial condition could be affected if:

     - LSI Logic does not win new product designs from major customers;

     - major customers reduce or cancel their existing business with LSI Logic;

     - major customers make significant changes in scheduled deliveries; or

     - there are declines in the prices of products that LSI Logic sells to
       these customers.

                                        23
   29

LSI LOGIC UTILIZES INDIRECT CHANNELS OF DISTRIBUTION OVER WHICH IT EXERCISES
LIMITED CONTROL.

     LSI Logic derives a material percentage of product revenues from
independent reseller and distributor channels. LSI Logic's financial results
could be adversely affected if its relationship with these resellers or
distributors were to deteriorate or if the financial condition of these
resellers or distributors were to decline. In addition, as LSI Logic's business
grows, it may have an increased reliance on indirect channels of distribution.
There can be no assurance that LSI Logic will be successful in maintaining or
expanding these indirect channels of distribution. This could result in the loss
of certain sales opportunities.

     Furthermore, the partial reliance on indirect channels of distribution may
reduce LSI Logic's visibility with respect to future business, thereby making it
more difficult to accurately forecast orders.

LSI LOGIC'S OPERATIONS ARE AFFECTED BY CYCLICAL FLUCTUATIONS.

     The semiconductor and SAN systems segments in which LSI Logic competes are
subject to cyclical fluctuations in demand. As a result, LSI Logic may
experience periodic declines in sales or the prices of its products as a result
of the following:

     - rapid technological change, product obsolescence and price erosion in its
       products;

     - maturing product cycles in its products or products sold by its
       customers;

     - increases in worldwide manufacturing capacity for semiconductors,
       resulting in declining prices; and

     - changes in general economic conditions, which may cause declines in its
       product markets or the markets of its suppliers and customers.

     The semiconductor industry has in the past experienced periods of rapid
expansion of production capacity. Even when the demand for LSI Logic's products
remains constant, the availability of additional excess production capacity in
the industry creates competitive pressure that can degrade pricing levels, which
can reduce revenues.

     Furthermore, customers who benefit from shorter lead times may defer some
purchases to future periods, which could affect LSI Logic's demand and revenues
for the short term. As a result, LSI Logic may experience downturns or
fluctuations in demand in the future and experience adverse effects on its
operating results and financial condition.

LSI LOGIC ENGAGES IN ACQUISITIONS AND ALLIANCES GIVING RISE TO ECONOMIC AND
TECHNOLOGICAL RISKS.

     LSI Logic intends to continue to make investments in companies, products
and technologies, either through acquisitions or investment alliances.

     Acquisitions and investment activities often involve risks, including the
need to:

     - acquire timely access to needed capital for investments related to
       acquisitions and alliances;

     - conduct acquisitions that are timely relative to existing business
       opportunities;

     - successfully prevail over competing bidders for target acquisitions at an
       acceptable price;

     - invest in companies and technologies that contribute to the growth of LSI
       Logic's business;

     - retain the key employees of the acquired operation;

     - incorporate acquired operations into LSI Logic's business and maintain
       uniform standards, controls and procedures; and

     - develop the capabilities necessary to exploit newly acquired
       technologies.

     Some of these factors are beyond LSI Logic's control. Failure to manage
growth effectively and to integrate acquisitions could adversely affect LSI
Logic's operating results and financial condition.

                                        24
   30

THERE IS UNCERTAINTY ASSOCIATED WITH LSI LOGIC'S RESEARCH AND DEVELOPMENT
INVESTMENTS.

     LSI Logic's research and development activities are intended to maintain
and enhance its competitive position by utilizing the latest advances in the
design and manufacture of semiconductors and storage systems including
networking, communications and storage technologies. Technical innovations are
inherently complex and require long development cycles and the commitment of
extensive engineering resources. LSI Logic must incur substantial research and
development costs to confirm the technical feasibility and commercial viability
of a product that in the end may not be successful. If LSI Logic is not able to
successfully and timely complete its research and development programs, it may
face competitive disadvantages. There is no assurance that LSI Logic will
recover the development costs associated with the programs or that it will be
able to secure the financial resources necessary to fund future research and
development efforts.

THE PRICE OF LSI LOGIC'S SECURITIES MAY BE AFFECTED BY A WIDE RANGE OF FACTORS.

     Some of the factors that may cause volatility in the price of LSI Logic's
securities include:

     - quarterly variations in financial results;

     - business and product market cycles;

     - fluctuations in customer requirements;

     - the availability and utilization of manufacturing capacity;

     - the timing of new product introductions; and

     - the ability to develop and implement new technologies.

     The price of LSI Logic's securities may also be affected by the estimates
and projections of the investment community, general economic and market
conditions and the cost of operations in one or more of LSI Logic's product
markets. While LSI Logic cannot predict the individual effect that these factors
may have on the price or its securities, these factors, either individually or
in the aggregate, could result in significant variations in price during any
given period of time.

LSI LOGIC'S GLOBAL OPERATIONS EXPOSE THE COMPANY TO NUMEROUS INTERNATIONAL
BUSINESS RISKS.

     LSI Logic has substantial business activities in Asia and Europe. Both
manufacturing and sales of LSI Logic's products may be adversely impacted by
changes in political and economic conditions abroad. A change in the current tax
laws, tariff structures, export laws, regulatory requirements or trade policies
in either the United States or foreign countries could adversely impact LSI
Logic's ability to manufacture or sell its products in foreign markets.
Moreover, a significant decrease in sales by LSI Logic's customers to end users
in either Asia or Europe could result in a decline in orders.

     LSI Logic subcontracts test and assembly functions to independent companies
located in Asia. A reduction in the number or capacity of qualified
subcontractors or a substantial increase in pricing could cause longer lead
times, delays in the delivery of products to customers, or increased costs.

THE HIGH TECHNOLOGY INDUSTRY IN WHICH LSI LOGIC OPERATES IS PRONE TO
INTELLECTUAL PROPERTY LITIGATION.

     LSI Logic's success is dependent in part on its technology and other
proprietary rights, and LSI Logic believes that there is value in the protection
afforded by its patents, patent applications and trademarks. However, the
industry is characterized by rapidly changing technology and LSI Logic's future
success depends primarily on the technical competence and creative skills of its
personnel, rather than on patent and trademark protection.

     As is typical in the high technology industry, from time to time LSI Logic
has received communications from other parties asserting that certain of its
products, processes, technologies or information infringe upon their patent
rights, copyrights, trademark rights or other intellectual property

                                        25
   31

rights. LSI Logic regularly evaluates these assertions. In light of industry
practice, LSI Logic believes with respect to existing or future claims that any
licenses or other rights that may be necessary can generally be obtained on
commercially reasonable terms. Nevertheless, there is no assurance that licenses
will be obtained on acceptable terms or that a claim will not result in
litigation or other administrative proceedings.

     In February of 1999, a lawsuit alleging patent infringement was filed in
the United States District Court for the District of Arizona by the Lemelson
Medical, Education & Research Foundation, Limited Partnership against 88
electronics industry companies, including LSI Logic. The case number is
CIV990377PHXRGS. The patents involved in this lawsuit are alleged to relate to
semiconductor manufacturing and computer imaging, including the use of bar
coding for automatic identification of articles. In September 1999, LSI Logic
filed an answer denying infringement, raising affirmative defenses and asserting
a counterclaim for declaratory judgment of non-infringement, invalidity and
unenforceability of Lemelson's patents. As of December 31, 2000, discovery had
commenced but no trial date had been set. While LSI Logic cannot make any
assurance regarding the eventual resolution of the matter, it does not believe
that the matter will have a material adverse effect on its consolidated results
of operations or financial condition.

LSI LOGIC MUST ATTRACT AND RETAIN KEY EMPLOYEES IN A HIGHLY COMPETITIVE
ENVIRONMENT.

     LSI Logic's employees are vital to its success, and its key management,
engineering and other employees are difficult to replace. LSI Logic does not
generally have employment contracts with its key employees. Further, LSI Logic
does not maintain key person life insurance on any of its employees. The
expansion of high technology companies in Silicon Valley, Colorado, Oregon and
elsewhere where LSI Logic operates its business has increased demand and
competition for qualified personnel. LSI Logic's continued growth and future
operating results will depend upon its ability to attract, hire and retain
significant numbers of qualified employees.

RISKS RELATED TO C-CUBE'S BUSINESS

     C-Cube is subject to risks similar to those described above under the
following subheadings:

     - LSI Logic operates in highly competitive markets;

     - LSI Logic engages in acquisition and alliances giving rise to economic
       and technological risks;

     - The price of LSI Logic's securities may be affected by a wide range of
       factors;

     - LSI Logic's global operations expose the company to numerous
       international business risks;

     - The high technology industry in which LSI Logic operates is prone to
       intellectual property litigation; and

     - LSI Logic must attract and retain key employees in a highly competitive
       environment.

     In addition, C-Cube is subject to a number of additional risks, including
those described below. Some of the additional risks are also similar to risks
described above relating to LSI Logic.

C-CUBE OPERATED PRIMARILY AS A SEMICONDUCTOR BUSINESS UNTIL 1996, WHEN IT
ACQUIRED THE DIVICOM BUSINESS. C-CUBE MAY INCUR LOSSES AS A RESULT OF OPERATING
SOLELY AS A SEMICONDUCTOR BUSINESS IN THE FUTURE.

     Since acquiring the DiviCom business in 1996 and prior to the
merger/spin-off in May 2000, C-Cube's operations consisted of the semiconductor
business and the DiviCom systems business. Before acquiring DiviCom, the systems
business did not represent a significant portion of C-Cube's overall business.
C-Cube alone cannot be sure that its operating results will not be adversely
affected by the loss of one or more of the following attributes. The DiviCom
acquisition allowed C-Cube, among other things:

     - the ability to leverage the DiviCom business's expertise in areas related
       to C-Cube's core competency in digital video compression;
                                        26
   32

     - to increase sales of C-Cube's products for set-top boxes and increase
       understanding of customer systems requirements;

     - the opportunity to jointly develop various communications products;

     - the ability to combine the expertise of the two businesses to serve the
       digital video networking market;

     - the ability to more effectively enable and cost reduce end-to-end video
       networking solutions;

     - the added benefit of a larger market capitalization due to the
       combination of an expanded systems business with a semiconductor
       business; and

     - the added diversification of serving the digital video, semiconductor and
       communications systems markets.

     It is possible that since C-Cube will not be able to provide a complete
broadcast/set-top solution as C-Cube was able to do with the additional DiviCom
products, customers will seek to find a complete solution elsewhere. Any loss of
the benefits provided by the combination with the DiviCom business could
seriously harm C-Cube's operating results, which would negatively affect the
value of your investment.

C-CUBE'S OPERATING RESULTS HAVE VARIED SIGNIFICANTLY IN THE PAST AND ARE LIKELY
TO VARY SIGNIFICANTLY IN THE FUTURE, AND ITS STOCK PRICE MAY DECLINE IF C-CUBE
FAILS TO MEET THE EXPECTATIONS OF ANALYSTS AND INVESTORS.

     C-Cube's quarterly and annual operating results have been and will likely
continue to be affected by a wide variety of factors that could have a negative
effect on revenue and profitability. Factors that have negatively affected
C-Cube's operating results in the past include:

     - availability, cost and manufacturing yield of raw materials, chip
       manufacturing capacity, assembly capacity, packages and test capacity
       from C-Cube's vendors;

     - competitive products and pressures on average selling prices on products
       supplied by C-Cube;

     - loss of strategic relationships in C-Cube's markets;

     - delay in the emergence of new markets in which C-Cube's products are
       used;

     - the level of expenditures for research and development, sales,
       administration and marketing needed to be successful in C-Cube's markets;
       and

     - the level of orders which are received and can be shipped in any given
       quarter.

     In the future, C-Cube's operating results could again be affected by one or
more of these factors or a wide variety of other factors that have not had an
adverse effect on C-Cube in the past.

     Further, a significant portion of C-Cube's expenses are fixed and the
timing of increases in expenses is based in large part on its forecast of future
revenue. As a result, if revenue does not meet C-Cube's expectations, it may be
unable to quickly adjust expenses to levels appropriate to actual revenue. Any
of the above factors could have an adverse effect on C-Cube's operating results.

IF SYSTEMS MANUFACTURERS DO NOT ACCEPT C-CUBE'S PRODUCTS OR IF NEW MARKETS FOR
ITS PRODUCTS DO NOT EMERGE, C-CUBE'S PRODUCTS COULD BECOME OBSOLETE AND
UNMARKETABLE OR REQUIRE C-CUBE TO REDESIGN ITS PRODUCTS, WHICH COULD BE COSTLY
AND TIME-CONSUMING.

     To date, C-Cube has derived substantially all of its product revenue from:

     - sales of products for video playback and karaoke;

     - video cards for computers and direct broadcast satellite applications;

     - sales of products for development;

                                        27
   33

     - trials and early deployment of broadcast; and

     - other applications that are not yet commercially available or are not yet
       in volume production.

     If C-Cube is unable to generate increased revenue from new opportunities
for digital video compression in the consumer electronics, computer and
communications markets or if systems manufacturers do no accept its products,
its results of operation would be harmed. Some of the potential new markets for
the compression of digital video into a more compact form, which provides
significant storage and transmission efficiencies, would require extensive
communications infrastructures that are not yet in place and that would likely
be expensive and heavily regulated by governmental entities. These new markets
may never materialize or they might not materialize for some time.

IF CHIP SUPPLIERS AND SUBCONTRACTORS ON WHICH C-CUBE DEPENDS DO NOT PERFORM,
C-CUBE WILL NOT BE ABLE TO FILL ORDERS FOR ITS PRODUCTS.

     All of C-Cube's products are currently manufactured to its specifications
by independent chip manufacturers called foundries, and C-Cube subcontracts to
third parties assembly, testing and packaging. If these chip suppliers on which
C-Cube depends are unable to provide it with the chips it needs to fill orders
for its products, its results of operations could suffer. Although C-Cube
primarily uses three foundries to manufacture its products, the majority of its
products are produced by only one of the foundries, and it is therefore
dependent on a single foundry for many of its products. This dependence on
single foundries subjects C-Cube to risks associated with an interruption in
supply from any such foundry.

     Furthermore, C-Cube obtains semiconductor chip manufacturing capacity
through forecasts that are generated many months in advance of expected delivery
dates and are binding. C-Cube's ability to obtain the capacity necessary to meet
the future demand for its products is based on its ability to accurately
forecast such future demand. If C-Cube fails to accurately forecast future
demand, it may be unable to timely obtain an adequate supply of chips necessary
to manufacture the number of products required to satisfy the actual demand.

C-CUBE DERIVES MUCH OF ITS PRODUCT REVENUE FROM SALES TO EMERGING GLOBAL
MARKETS. WITHOUT THE DIVICOM BUSINESS DIVERSIFICATION, C-CUBE'S BUSINESS MIGHT
BE MORE SUSCEPTIBLE TO FLUCTUATIONS IN EMERGING MARKET ECONOMIES.

     To date, C-Cube has derived a substantial portion of its revenue from sales
of its video compact disc products in China. Without DiviCom's growth in sales
to Europe and the United States, C-Cube's sales growth is less geographically
diversified which may limit its ability to offset the effect of downturns in
emerging global markets on its results of operations which might have a negative
effect on C-Cube's results of operations. C-Cube expects that revenue from video
compact disc products will decrease as a percentage of total revenue, but
continue to account for a significant portion of its product revenue in 2001.

SEASONAL TRENDS MAY CAUSE C-CUBE'S QUARTERLY OPERATING RESULTS TO FLUCTUATE,
WHICH MAY ADVERSELY AFFECT THE MARKET PRICE OF C-CUBE COMMON STOCK.

     A significant portion of C-Cube's sales revenue comes from the consumer and
communications markets, both of which are characterized by seasonal sales. Both
markets tend to experience higher sales in the third and fourth calendar
quarters due to holiday purchases by system manufacturers and relatively less
strong sales in the first and second calendar quarters. Though seasonality
affects C-Cube less and less due to diversified product lines, seasonal trends
may still cause C-Cube's operating results to fluctuate which may have an
adverse effect on its stock price.

                                        28
   34

IF C-CUBE IS UNABLE TO ADEQUATELY PROTECT ITS INTELLECTUAL PROPERTY, THIRD
PARTIES COULD USE C-CUBE'S INTELLECTUAL PROPERTY WITHOUT ITS CONSENT.

     C-Cube's products are primarily based on technology that was developed
internally which C-Cube protects through a combination of patents, copyrights
and trade secret law, confidentiality procedures and licensing arrangements.
C-Cube's operating results depend, in part, on C-Cube's ability to protect its
technology. Unauthorized parties may attempt to obtain and use C-Cube's
proprietary information which might negatively affect the value of its stock.
Policing unauthorized use of C-Cube's proprietary information is difficult, and
C-Cube does not know whether the steps it has taken will prevent
misappropriation, particularly in foreign countries where the laws may not
protect its proprietary rights as fully as in the United States.

C-CUBE'S HISTORICAL FINANCIAL INFORMATION MAY NOT BE REPRESENTATIVE OF ITS
RESULTS AS A SEPARATE COMPANY.

     C-Cube's historical financial information shown in its audited financial
statements does not necessarily reflect what its financial position, results of
operations and cash flows would have been had C-Cube been a separate,
stand-alone entity during the periods presented. In addition, the historical
information is not necessarily indicative of what C-Cube's results of
operations, financial position and cash flows will be in the future. C-Cube has
not made adjustments to reflect many significant changes that will occur in its
cost structure, funding and operations as a result of its separation from C-Cube
Microsystems, including changes in C-Cube's employee base, changes in its legal
structure, increased costs associated with reduced economies of scale, increased
marketing expenses related to establishing a new brand identity and increased
costs associated with being a public, stand-alone company.

C-CUBE RELIES ON A CONTINUOUS POWER SUPPLY TO CONDUCT ITS OPERATIONS, AND
CALIFORNIA'S CURRENT ENERGY CRISIS COULD DISRUPT ITS OPERATIONS AND INCREASE ITS
EXPENSES.

     California is in the midst of an energy crisis that could disrupt C-Cube's
operations and increase its expenses. In the event of an acute power shortage,
that is, when power reserves for the State of California fall below 1.5%,
California has on some occasions implemented, and may in the future continue to
implement, rolling blackouts throughout California. C-Cube currently does not
have backup generators or alternate sources of power in the event of a blackout,
and its current insurance does not provide coverage for any damages C-Cube or
its customers may suffer as a result of any interruption in its power supply. If
blackouts interrupt C-Cube's power supply, it would be temporarily unable to
continue operations at some of its facilities. Any such interruption in C-Cube's
ability to continue operations at its facilities could damage its reputation,
harm its ability to retain existing customers and to obtain new customers, and
could result in lost revenue, any of which could substantially harm its business
and results of operations.

     Furthermore, the deregulation of the energy industry instituted in 1996 by
the California government has caused power prices to increase. Under
deregulation, utilities were encouraged to sell their plants, which
traditionally had produced most of California's power, to independent energy
companies that were expected to compete aggressively on price. Instead, due in
part to a shortage of supply, wholesale prices have skyrocketed over the past
year. If wholesale prices continue to increase, C-Cube's operating expenses will
likely increase, as its principal facilities are located in California.

                                THE TRANSACTION

GENERAL DESCRIPTION OF THE EXCHANGE OFFER

     LSI Logic is offering to exchange 0.79 of a share of LSI Logic common stock
for each outstanding share of C-Cube common stock validly tendered and not
properly withdrawn, subject to the terms and conditions described in this
prospectus and the related letter of transmittal.

     The expiration date of the exchange offer is 12:00 midnight, New York time,
on May 10, 2001, unless LSI Logic extends the period of time for which the
exchange offer is open, in which case the term "expiration date" means the
latest time and date on which the exchange offer, as so extended, expires.

     If you are the record owner of your shares of C-Cube common stock and you
tender those shares directly to the Exchange Agent, you will not incur any
brokerage fees or commissions. If you own your shares of C-Cube common stock
through a broker or other nominee, and your broker tenders those shares on your
behalf, your broker may charge you a commission for doing so. You should consult
with your broker or nominee to determine whether any charges will apply. Under
the terms of the merger agreement, LSI Logic is required to be responsible for
any transfer taxes on the exchange of shares of C-Cube common stock pursuant to
the exchange offer that are imposed on the acquiror of the shares of C-Cube
common stock. You will be responsible for any transfer taxes that are imposed on
the transferor.

     LSI Logic's obligation to deliver shares of LSI Logic common stock in
exchange for shares of C-Cube common stock pursuant to the exchange offer is
subject to several conditions referred to below in the section entitled "Certain
Terms of the Merger Agreement -- Conditions to the Exchange Offer."

PURPOSE OF THE EXCHANGE OFFER

     LSI Logic is making the exchange offer in order to acquire all of the
outstanding shares of C-Cube common stock. LSI Logic intends, as soon as
practicable after completion of the exchange offer, to have its wholly owned
subsidiary, Clover Acquisition Corp., the purchaser in the exchange offer, merge
with C-Cube. The purpose of the merger is to acquire all shares of C-Cube common
stock not tendered and exchanged pursuant to the exchange offer. In the merger,
each then outstanding share of C-Cube common stock, except for treasury shares
and shares that LSI Logic or Clover Acquisition Corp. holds for its own account,
and, if applicable, shares of C-Cube common stock held by stockholders
exercising appraisal rights, would be converted into 0.79 of a share of LSI
Logic common stock, the same fraction of a share of LSI Logic common stock being
issued in exchange for each share of C-Cube common stock accepted for exchange
in the exchange offer.

EXTENSION; TERMINATION AND AMENDMENT

     Subject to the terms of the merger agreement, LSI Logic has agreed to
extend the exchange offer for successive extension periods not in excess of 10
business days per extension if, at the scheduled expiration date of the exchange
offer, any condition to the exchange offer has not been satisfied or, where
permissible, waived. In addition, LSI Logic is entitled to extend the exchange
offer if required by the rules of the Securities and Exchange Commission or The
New York Stock Exchange. During an extension, all shares of C-Cube common stock
previously tendered and not properly withdrawn will remain subject to the
exchange offer, subject to your right to withdraw your shares of C-Cube common
stock. You should read the discussion below in the section entitled
"-- Withdrawal Rights" for more details.

     LSI Logic reserves the right to make any changes in the terms and
conditions of the exchange offer by giving oral or written notice of the change
to the Exchange Agent and by making a public announcement. However, without the
prior written consent of C-Cube, LSI Logic cannot:

     - decrease the number of shares of C-Cube common stock sought in the
       exchange offer;

     - make any changes to the form or amount of consideration to be issued or
       paid for shares of C-Cube common stock in the exchange offer;

     - impose any additional conditions on the exchange offer other than those
       already described in the merger agreement;

                                        30
   36

     - amend or waive the minimum tender condition or other specified conditions
       as described in the merger agreement;

     - extend the initial expiration date of the exchange offer, except under
       circumstances described in the merger agreement; or

     - make any other change to the terms and conditions of the exchange offer
       which is adverse to the holders of shares of C-Cube common stock.

     LSI Logic is required to follow any extension, termination, amendment or
delay, as promptly as practicable, with a public announcement. In the case of an
extension, the announcement is required to be issued no later than 9:00 a.m.,
New York time, on the next business day after the previously scheduled
expiration date. Subject to applicable law, including Rules 14d-4(d) and
14d-6(c) under the Securities Exchange Act of 1934, which require that any
material change in the information published, sent or given to stockholders in
connection with the exchange offer be promptly sent to stockholders in a manner
reasonably designed to inform stockholders of the change, and without limiting
the manner in which LSI Logic may choose to make any public announcement, LSI
Logic assumes no obligation to publish, advertise or otherwise communicate any
public announcement other than by making a release to the Dow Jones News
Service.

     If LSI Logic makes a material change in the terms of the exchange offer or
the information concerning the exchange offer, or if it waives a material
condition of the exchange offer, LSI Logic will extend the exchange offer to the
extent required under the Securities Exchange Act of 1934. If, prior to the
expiration date and after obtaining C-Cube's prior written consent, LSI Logic
changes the percentage of shares of C-Cube common stock being sought or the
consideration offered to you, that change will apply to all stockholders whose
shares of C-Cube common stock are accepted for exchange pursuant to the exchange
offer. If at the time notice of that change is first published, sent or given to
you, the exchange offer is scheduled to expire at any time earlier than the
tenth business day from and including the date that the notice is first so
published, sent or given, LSI Logic is required to extend the exchange offer
until the expiration of that 10 business day period. For purposes of the
exchange offer, a "business day" means any day other than a Saturday, Sunday or
federal holiday and consists of the time period from 12:01 a.m. through 12:00
midnight, New York time.

SUBSEQUENT OFFERING PERIOD

     LSI Logic may elect to provide a subsequent offering period of three to 20
business days after the acceptance of shares of C-Cube common stock in the
exchange offer if the requirements of Rule 14d-11 under the Securities Exchange
Act of 1934 have been met. You will not have the right to withdraw any shares of
C-Cube common stock that you tender during the subsequent offering period. LSI
Logic is required to accept for exchange, and to deliver shares of LSI Logic
common stock in exchange for, shares of C-Cube common stock that are validly
tendered and not properly withdrawn, promptly after they are tendered during any
subsequent offering period. If LSI Logic elects to provide a subsequent offering
period, it is required to make a public announcement to that effect no later
than 9:00 a.m., New York time, on the next business day after the previously
scheduled expiration date.

EXCHANGE OF SHARES OF C-CUBE COMMON STOCK; DELIVERY OF SHARES OF LSI LOGIC
COMMON STOCK

     Upon the terms of, and subject to the conditions to, the exchange offer
including, if the exchange offer is extended or amended, the terms and
conditions of the extension or amendment, LSI Logic is required to accept for
exchange, and to deliver shares of LSI Logic common stock in exchange for,
shares of C-Cube common stock that are validly tendered and not properly
withdrawn, promptly after the expiration date and promptly after they are
tendered during any subsequent offering period. In all cases,

                                        31
   37

exchange of shares of C-Cube common stock tendered and C-Cube accepted for
exchange pursuant to the exchange offer will be made only after timely receipt
by the Exchange Agent of:

     - certificates for the shares of C-Cube common stock or a confirmation of a
       book-entry transfer of the shares of C-Cube common stock in the Exchange
       Agent's account at The Depository Trust Company, which is referred to in
       this prospectus as "DTC"; and

     - a properly completed and duly executed letter of transmittal or a
       manually signed facsimile of that document, and any other required
       documents.

     For purposes of the exchange offer, LSI Logic will be deemed to have
accepted for exchange shares of C-Cube common stock validly tendered and not
properly withdrawn as, if and when LSI Logic notifies the Exchange Agent of its
acceptance of the tenders of those shares of C-Cube common stock. The Exchange
Agent is required to then deliver shares of LSI Logic common stock and cash
instead of fractional shares of LSI Logic common stock in exchange for the
shares of C-Cube common stock promptly after receipt of the notice referred to
in the preceding sentence. The Exchange Agent will act as agent for LSI Logic
for the purpose of receiving shares of LSI Logic common stock and any cash to be
paid instead of any fractional shares of LSI Logic common stock and transmitting
a certificate or certificates for LSI Logic common stock and cash, if any, to
you. You will not receive any interest on any cash that LSI Logic pays to you,
even if there is a delay in making the exchange.

     If LSI Logic does not accept any tendered shares of C-Cube common stock for
exchange pursuant to the terms and conditions of the exchange offer for any
reason, or if certificates are submitted for more shares of C-Cube common stock
than are accepted, LSI Logic is required to return certificates for the
unexchanged shares of C-Cube common stock to the tendering stockholder or, in
the case of shares of C-Cube common stock tendered by book-entry transfer of
unexchanged shares of C-Cube common stock into the Exchange Agent's account at
the address on the back page of this prospectus, pursuant to the procedures
described below in the section entitled "-- Procedure for Tendering," the shares
of C-Cube common stock will be credited to an account maintained within DTC, as
soon as practicable following expiration or termination of the exchange offer.

CASH INSTEAD OF FRACTIONAL SHARES OF LSI LOGIC COMMON STOCK

     LSI Logic will not issue certificates representing fractional shares of its
common stock in the exchange offer. Instead, each tendering stockholder who
would otherwise be entitled to a fractional share (after aggregating all
fractional shares of LSI Logic common stock that otherwise would be received by
the holder) will receive cash (rounded up to the nearest whole cent), without
interest, equal to the product of multiplying 0.79 by the average closing sale
price of one share of LSI Logic common stock on The New York Stock Exchange
during the 10 trading days ending on the trading day immediately prior to the
expiration of the exchange offer, as it may be extended.

WITHDRAWAL RIGHTS

     Your tender of shares of C-Cube common stock pursuant to the exchange offer
is irrevocable, except that, other than during a subsequent offering period,
shares of C-Cube common stock tendered pursuant to the exchange offer may be
withdrawn at any time prior to the expiration date, and, unless LSI Logic
previously accepted them for exchange pursuant to the exchange offer, may also
be withdrawn at any time after June 11, 2001. If LSI Logic elects to provide a
subsequent offering period in accordance with Rule 14d-11 under the Securities
Exchange Act of 1934, you will not have the right to withdraw any shares of
C-Cube common stock that you tender during the subsequent offering period.

     For your withdrawal to be effective, the Exchange Agent must receive from
you a written, telex or facsimile transmission notice of withdrawal at its
address on the back cover of this prospectus, and your notice must include your
name, address, social security number, the certificate number(s) and the number
of shares of C-Cube common stock to be withdrawn as well as the name of the
registered holder, if it is different from that of the person who tendered the
shares of C-Cube common stock.

                                        32
   38

     A financial institution must guarantee all signatures on the notice of
withdrawal unless the shares of C-Cube common stock have been tendered for the
account of any eligible institution. Most banks, savings and loan associations
and brokerage houses are able to provide these signature guarantees for you. The
financial institution must be an "eligible institution" which means it is a
participant in the Securities Transfer Agents Medallion Program. If shares of
C-Cube common stock have been tendered pursuant to the procedures for book-entry
tender discussed under the caption below entitled "Procedure for Tendering," any
notice of withdrawal must specify the name and number of the account at DTC to
be credited with the withdrawn shares of C-Cube common stock and must otherwise
comply with the DTC procedures. If certificates have been delivered to the
Exchange Agent, the name of the registered stockholder and the serial numbers of
the particular certificates evidencing the shares of C-Cube common stock
withdrawn must also be furnished to the Exchange Agent, as stated above, prior
to the physical release of the certificates. LSI Logic will decide all questions
regarding the form and validity (including time of receipt) of any notice of
withdrawal, in its sole discretion, and LSI Logic's decision shall be final and
binding.

     Neither LSI Logic, the Exchange Agent, the Information Agent nor any other
person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or will incur any liability for
failure to give proper notification. Any shares of C-Cube common stock properly
withdrawn will be deemed not to have been validly tendered for purposes of the
exchange offer. However, you may retender withdrawn shares of C-Cube common
stock by following one of the procedures discussed below in the sections
entitled "-- Procedure for Tendering" or "-- Guaranteed Delivery" at any time
prior to the expiration date.

PROCEDURE FOR TENDERING

     For you to validly tender shares of C-Cube common stock pursuant to the
exchange offer, (a) the enclosed letter of transmittal, properly completed and
duly executed or a manually executed facsimile of that document, along with any
required signature guarantees, or an agent's message in connection with a
book-entry transfer, and any other required documents, must be transmitted to
and received by the Exchange Agent at the address on the back cover of this
prospectus, and certificates for tendered shares of C-Cube common stock must be
received by the Exchange Agent at that address or the shares of C-Cube common
stock must be tendered pursuant to the procedures for book-entry tender
described below (and a confirmation of receipt of the tender received, which
confirmation LSI Logic refers to below as a "book-entry confirmation"), in each
case before the expiration date, or (b) you must comply with the guaranteed
delivery procedures described below.

     The term "agent's message" means a message, transmitted by DTC to, and
received by, the Exchange Agent and forming a part of a book-entry confirmation,
which states that DTC has received an express acknowledgment from the
participant in DTC tendering the shares of C-Cube common stock which are the
subject of the book-entry confirmation, that the participant has received and
agrees to be bound by the terms of the letter of transmittal and that LSI Logic
may enforce that agreement against the participant.

     The Exchange Agent is required to establish accounts with respect to the
shares of C-Cube common stock at DTC for purposes of the exchange offer by April
17, 2001, and any financial institution that is a participant in DTC may make
book-entry delivery of the shares of C-Cube common stock by causing DTC to
transfer tendered shares of C-Cube common stock into the Exchange Agent's
account in accordance with DTC's procedure for the transfer. However, although
delivery of shares of C-Cube common stock may be effected through book-entry at
DTC, the letter of transmittal (or a manually signed facsimile thereof), with
any required signature guarantees, or an agent's message in connection with a
book-entry transfer, and any other required documents, must, in any case, be
transmitted to and received by the Exchange Agent at the address on the back
cover of this prospectus prior to the expiration date, or the guaranteed
delivery procedures described below must be followed.

     Signatures on all letters of transmittal must be guaranteed by an eligible
institution, except in cases in which shares of C-Cube common stock are tendered
either by a registered holder of shares of C-Cube

                                        33
   39

common stock who has not completed the box entitled "Special Issuance
Instructions" on the letter of transmittal or for the account of an eligible
institution.

     If the certificates for shares of C-Cube common stock are registered in the
name of a person other than the person who signs the letter of transmittal, or
if certificates for unexchanged shares of C-Cube common stock are to be issued
to a person other than the registered holder(s), the certificates must be
endorsed or accompanied by appropriate stock powers, in either case signed
exactly as the name or names of the registered owner or owners appear on the
certificates, with the signature(s) on the certificates or stock powers
guaranteed in the manner LSI Logic has described above.

     THE METHOD OF DELIVERY OF C-CUBE STOCK CERTIFICATES AND ALL OTHER REQUIRED
DOCUMENTS, INCLUDING DELIVERY THROUGH DTC, IS AT YOUR OPTION AND RISK, AND THE
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE EXCHANGE AGENT.
IF DELIVERY IS BY MAIL, LSI LOGIC RECOMMENDS REGISTERED MAIL WITH RETURN RECEIPT
REQUESTED, PROPERLY INSURED. IN ALL CASES, YOU SHOULD ALLOW SUFFICIENT TIME TO
ENSURE TIMELY DELIVERY.

GUARANTEED DELIVERY

     If you wish to tender shares of C-Cube common stock pursuant to the
exchange offer and your certificates are not immediately available or you cannot
deliver the certificates and all other required documents to the Exchange Agent
prior to the expiration date or cannot complete the procedure for book-entry
transfer on a timely basis, your shares of C-Cube common stock may nevertheless
be tendered, so long as all of the following conditions are satisfied:

     - You make your tender by or through an eligible institution;

     - The enclosed notice of guaranteed delivery, properly completed and duly
       executed, substantially in the form enclosed with this prospectus, is
       received by the Exchange Agent as provided below on or prior to the
       expiration date; and

     - The certificates for all tendered shares of C-Cube common stock or a
       confirmation of a book-entry transfer of tendered securities into the
       Exchange Agent's account at DTC as described above, in proper form for
       transfer, together with a properly completed and duly executed letter of
       transmittal or a manually signed facsimile thereof, with any required
       signature guarantees (or, in the case of a book-entry transfer, an
       agent's message) and all other documents required by the letter of
       transmittal are received by the Exchange Agent within three New York
       Stock Exchange trading days, after the date of execution of the notice of
       guaranteed delivery.

     You may deliver the notice of guaranteed delivery by hand or transmit it by
facsimile transmission or mail to the Exchange Agent and you must include a
signature guarantee by an eligible institution in the form provided in that
notice.

     In all cases, LSI Logic is required to exchange shares of C-Cube common
stock tendered and accepted for exchange pursuant to the exchange offer only
after timely receipt by the Exchange Agent of certificates for shares of C-Cube
common stock (or timely confirmation of a book-entry transfer of tendered
securities into the Exchange Agent's account at DTC as described above),
properly completed and duly executed letter(s) of transmittal or manually signed
facsimile(s) thereof, or an agent's message in connection with a book-entry
transfer, and any other required documents.

     By executing a letter of transmittal as described above, you irrevocably
appoint LSI Logic's designees as your attorneys-in-fact and proxies, each with
full power of substitution, to the full extent of your rights with respect to
your shares of C-Cube common stock tendered and accepted for exchange by LSI
Logic and with respect to any and all other shares of C-Cube common stock and
other securities (other than the shares of LSI Logic common stock) issued or
issuable in respect of the shares of C-Cube common stock on or after May 10,
2001. That appointment is effective if and when, and only to the extent that,
LSI Logic accepts the shares of C-Cube common stock for exchange pursuant to the
exchange offer. All of these proxies shall be considered coupled with an
interest in the tendered shares of C-Cube common

                                        34
   40

stock and therefore shall not be revocable. Upon the effectiveness of the
appointment, all prior proxies that you have given will be revoked, and you may
not give any subsequent proxies (and, if given, they will not be deemed
effective). LSI Logic's designees will, with respect to the shares of C-Cube
common stock for which the appointment is effective, be empowered, among other
things, to exercise all of your voting and other rights as they, in their sole
discretion, deem proper at any annual, special or adjourned meeting of C-Cube
stockholders or otherwise. LSI Logic reserves the right to require that, in
order for shares of C-Cube common stock to be deemed validly tendered,
immediately upon LSI Logic's exchange of the shares, LSI Logic must be able to
exercise full voting rights with respect to the tendered shares of C-Cube common
stock.

     LSI Logic will determine questions regarding the validity, form,
eligibility (including time of receipt) and acceptance for exchange of any
tender of shares of C-Cube common stock, in its sole discretion, and its
determination shall be final and binding. LSI Logic reserves the absolute right
to reject any and all tenders of shares of C-Cube common stock that it
determines are not in proper form or the acceptance of or exchange for which
may, in the opinion of its counsel, be unlawful. LSI Logic also reserves the
absolute right to waive any defect or irregularity in the tender of any shares
of C-Cube common stock. No tender of shares of C-Cube common stock will be
deemed to have been validly made until all defects and irregularities in tenders
of shares of C-Cube common stock have been cured or waived. Neither LSI Logic,
the Exchange Agent, the Information Agent nor any other person will be under any
duty to give notification of any defects or irregularities in the tender of any
shares of C-Cube common stock or will incur any liability for failure to give
notification. LSI Logic's interpretation of the terms and conditions of the
exchange offer (including the letter of transmittal and instructions thereto)
will be final and binding.

     The tender of shares of C-Cube common stock pursuant to any of the
procedures described above will constitute a binding agreement between LSI Logic
and you upon the terms and subject to the conditions to the exchange offer.

BACKGROUND OF THE TRANSACTION

     The merger agreement and the terms and conditions of the exchange offer and
the merger are the result of arm's length negotiations between representatives
of LSI Logic and representatives of C-Cube. Described below is a summary of the
background of these negotiations.

     LSI Logic and C-Cube have been familiar with each other's businesses for
many years. Senior executives of the two companies have encountered one another
in a number of business and industry settings and, at various times over the
past four years have discussed the possibility of entering into a strategic
relationship involving LSI Logic and C-Cube's semiconductor business.

     In August 1997, Bryon Look, LSI Logic's then Vice President of Corporate
Development, met with representatives of C-Cube to discuss a possible strategic
relationship involving LSI Logic and C-Cube's semiconductor business. From
August 1997 until October 1997, LSI Logic and C-Cube held other discussions
regarding a strategic relationship and engaged in various levels of analysis
regarding such a relationship; however, in October 1997, C-Cube's board of
directors determined that it was in the best interests of C-Cube and its
stockholders to continue operations as a stand-alone entity and to retain its
semiconductor business.

     In May 1999, LSI Logic executives again considered a possible relationship
involving LSI Logic and C-Cube's semiconductor business, but after preliminary
internal discussions, did not pursue any further contacts with C-Cube with
respect to such a relationship at that time.

     In October 1999, C-Cube announced its plans to restructure the company by
separating its semiconductor business into a subsidiary, C-Cube Semiconductor
Inc., either selling its semiconductor business to a third party or distributing
the shares of C-Cube Semiconductor Inc. to the then-current C-Cube stockholders
and merging the remainder of C-Cube, which consisted primarily of its DiviCom
business, into a public company known as Harmonic Inc.

     On October 28, 1999, Wilfred Corrigan, LSI Logic's Chief Executive Officer,
sent a letter to Alex Balkanski, C-Cube's then Chief Executive Officer, in which
Mr. Corrigan expressed LSI Logic's renewed interest in potentially acquiring
C-Cube's semiconductor business.

     In November 1999, at C-Cube's direction, C-Cube's financial advisor, Credit
Suisse First Boston, contacted Mr. Corrigan and requested that LSI Logic submit
a written indication of interest to acquire C-Cube's semiconductor business.

     LSI Logic submitted a nonbinding indication of interest relating to
C-Cube's semiconductor business in December 1999 which was discussed by C-Cube's
board of directors at a meeting on December 14, 1999. After discussion, C-Cube's
board of directors determined that a sale of C-Cube's semiconductor business to
LSI Logic was not appropriate and that it was in the best interests of C-Cube
and its stockholders to continue operations as a stand-alone company. Mr.
Corrigan was subsequently informed of C-Cube's board of directors' decision not
to enter into further negotiations with LSI Logic, and the discussions regarding
the potential transaction were discontinued.

     In early May 2000, the spin-off of C-Cube's semiconductor business was
completed and C-Cube was merged with Harmonic Inc. A complete description of the
spin-off and the merger of C-Cube with Harmonic Inc. is summarized in the
section entitled "Summary -- The Companies" and in the section entitled
"Information Relating to C-Cube -- May 2000 Restructuring" in this prospectus.

     In early 2001, C-Cube's board of directors authorized C-Cube's management
to consider possible strategic alternatives available to C-Cube. Shortly
thereafter, members of C-Cube's management began discussing alternatives with
C-Cube's financial advisor, including the possibility of contacting third
parties to solicit their interest in a transaction with C-Cube. Thereafter, at
the direction of C-Cube, Credit Suisse First Boston contacted several companies
that were identified as potential business combination candidates. On March 7,
2001, representatives of C-Cube contacted Mr. Look to determine LSI Logic's
level of interest in discussions regarding a potential business combination.

     On March 8, 2001, Mr. Corrigan, Mr. Look and other members of LSI Logic's
executive management team held a meeting to consider a potential business
combination with C-Cube. At the meeting, LSI Logic's executive team decided that
LSI Logic would be interested in re-commencing discussions with C-Cube.

     As a result of Credit Suisse First Boston's efforts to contact companies
that had expressed an interest in a potential business combination with C-Cube,
several non-binding expressions of interest were received by C-Cube. On March 9,
2001, LSI Logic submitted a non-binding expression of interest to C-Cube
outlining possible terms of a business combination transaction involving C-Cube
and LSI Logic. During the week of March 12, 2001, several other companies that
had expressed an interest in a transaction with C-Cube executed confidentiality
agreements with C-Cube, which permitted them to exchange additional information
concerning their respective businesses, organizations, financial condition and
results of operations.

     On March 15, 2001, C-Cube's board of directors met with representatives of
Wilson Sonsini Goodrich & Rosati, outside legal counsel to C-Cube, and Credit
Suisse First Boston to discuss the current market environment and the
expressions of interest that C-Cube had received. C-Cube's board of directors
directed C-Cube's management team to continue pursuing the expressions of
interest.

     On March 16, 2001, LSI Logic and C-Cube entered into a mutual
confidentiality agreement. LSI Logic then provided a due diligence request list
to C-Cube. Representatives of both companies, and their respective outside legal
counsel, including Cooley Godward LLP acting as outside legal counsel to LSI
Logic, and financial advisors, including Dresdner Kleinwort Wasserstein acting
as financial advisor to LSI Logic, exchanged various telephone calls with a view
toward preparing for additional due diligence efforts. The due diligence efforts
continued from March 17, 2001 through March 26, 2001.

     Between March 17 and March 24, 2001, C-Cube continued to pursue discussions
with various other parties which had submitted nonbinding expressions of
interest relating to the possible acquisition of or

                                        36
   42

business combination transaction with C-Cube, and continued its legal and
financial due diligence investigation of and management discussions with these
other parties.

     On March 20, 2001, members of LSI Logic's management and representatives of
LSI Logic's financial advisor met with members of C-Cube's management and
representatives of C-Cube's legal counsel and financial advisor to discuss the
two companies' businesses and the possibility of a business combination. LSI
Logic's management was represented by Mr. Corrigan, Mr. Look, now LSI Logic's
Chief Financial Officer and Executive Vice President, Giuseppe Staffaroni, LSI
Logic's Executive Vice President, Broadband Communications, Hemant Thapar, LSI
Logic's Vice President, Broadband Access Division, Robert Brown, LSI Logic's
Director of Business Development, and David Pursel, LSI Logic's Vice President,
General Counsel and Secretary. C-Cube's management was represented by Umesh
Padval, C-Cube's President and Chief Executive Officer, Didier Le Gall, C-Cube's
Chief Technical Officer and Senior Vice President, Research and Development,
Howard Bailey, C-Cube's Chief Financial Officer, Patrick Henry, C-Cube's Senior
Vice President, Marketing and Corporate Development, and Chris Adams, C-Cube's
Vice President, Broadband Marketing.

     On or about March 21, 2001, C-Cube and Wilson Sonsini Goodrich & Rosati
circulated an initial draft of the merger agreement to LSI Logic and Cooley
Godward, and to various other parties which had submitted expressions of
interest. C-Cube requested comments to the initial draft of the merger agreement
as a means to determine the level of commitment and interest of LSI Logic and
the other parties in completing a potential transaction with C-Cube.

     On March 23, 2001, LSI Logic's board of directors held a telephonic meeting
to discuss a potential business combination with C-Cube. Present from LSI Logic
management during this conference call were Mr. Corrigan, Mr. Look, Mr.
Staffaroni, Mr. Brown and Mr. Pursel. Also present on the call were
representatives of Cooley Godward and, for a portion of the call,
representatives of Dresdner Kleinwort Wasserstein. Dresdner Kleinwort
Wasserstein presented its preliminary financial review of C-Cube and the
proposed business combination. LSI Logic's board of directors discussed, among
other things, the possible synergies of combining LSI Logic with C-Cube and the
possible benefits and risks to LSI Logic of such a combination. LSI Logic's
board of directors authorized LSI Logic's management to continue its discussions
with C-Cube and to proceed with negotiation of a merger agreement.

     Also on March 23, 2001, counsel for LSI Logic prepared and sent to Wilson
Sonsini Goodrich & Rosati its comments to the initial draft of the merger
agreement. C-Cube and LSI Logic continued to negotiate the terms of the merger
agreement from this date through March 26, 2001, the date the definitive merger
agreement was executed.

     On March 24, 2001, at a special meeting of C-Cube's board of directors,
C-Cube's management, legal counsel and financial advisor updated C-Cube's board
of directors on the progress of the discussions with parties that had submitted
expressions of interest. Representatives from Wilson Sonsini Goodrich & Rosati
reported that, as of that date, only one of the companies, LSI Logic, had
responded to the draft merger agreement. Representatives of Wilson Sonsini
Goodrich & Rosati summarized the form of merger agreement that had been provided
to LSI Logic and highlighted the issues identified by LSI Logic in its comments
to the draft merger agreement. C-Cube's board of directors was also informed
that LSI Logic had expressed an unwillingness to participate in a bidding
process and that LSI Logic's proposal would be withdrawn on March 26, 2001.
C-Cube's board of directors considered LSI Logic's proposal as well as other
potential alternatives. In its deliberations, C-Cube's board of directors
discussed, among other things, LSI Logic's product lines, business strategy,
competitive position and the value and trading pattern of its common stock,
regulatory and other legal issues, LSI Logic's proposed exchange ratio and the
other terms of LSI Logic's proposal. C-Cube's board of directors determined that
C-Cube's management and its legal counsel and financial advisor should continue
to pursue and evaluate a potential transaction with LSI Logic with a view toward
entering into a definitive merger agreement with LSI Logic.

     On March 25, 2001, LSI Logic's board of directors held a meeting at which
they reviewed the terms of the proposed merger agreement. Representatives of
Dresdner Kleinwort Wasserstein discussed with LSI Logic's board of directors
materials relating to the valuation of C-Cube, and representatives of Cooley
                                        37
   43

Godward discussed with LSI Logic's board of directors the material terms of the
proposed merger agreement. At this meeting, Dresdner Kleinwort Wasserstein
delivered to LSI Logic's board of directors an oral opinion, which was
subsequently confirmed in writing, that based on and subject to the matters
described in its opinion, the proposed exchange ratio was fair, from a financial
point of view, to LSI Logic. After the discussion, the directors present at the
meeting voted to approve the merger agreement and the related agreements and the
transactions contemplated by the merger agreement and the related agreements,
including the exchange offer, subject to successful completion of negotiations,
and authorized the officers of LSI Logic to complete negotiations and finalize
and execute the merger agreement and related agreements.

     C-Cube's board of directors also held a meeting on March 25, 2001, and met
with C-Cube's management, outside legal counsel and financial advisor to receive
an update on their due diligence investigations and the status of negotiations.
C-Cube's board of directors reviewed the terms of LSI Logic's proposal, based on
the proposed merger agreement and other materials previously circulated to the
board. This meeting also included discussions by Wilson Sonsini Goodrich &
Rosati of the material terms of LSI Logic's proposed transaction and a review by
Credit Suisse First Boston of the financial aspects of the proposed transaction.

     In its deliberations, C-Cube's board of directors considered the exchange
ratio and other terms of LSI Logic's proposal and the fact that no other
potentially interested parties had responded to the initial draft of the merger
agreement. C-Cube's board of directors further weighed the advantages and
disadvantages of each of the nonbinding expressions of interest received from
other parties including, among other things, the relative value of the form of
consideration, the nature of the businesses to be combined, the level of
interest expressed by the other parties, the estimated time required to
negotiate and complete a transaction and regulatory issues in connection with a
potential transaction. C-Cube's board of directors again noted that LSI Logic
had indicated that it would not participate in a bidding process and that its
proposal would be withdrawn on March 26, 2001. C-Cube's board of directors
elected to adjourn the meeting and directed representatives of C-Cube's legal
counsel and financial advisor to express C-Cube's concern over some of LSI
Logic's proposed terms in the merger agreement.

     Later in the evening of March 25, 2001, C-Cube's board of directors
reconvened to discuss LSI Logic's response to C-Cube's expression of concern
relating to certain proposed terms of the merger agreement and to discuss the
most recent negotiations with LSI Logic. After further deliberations, C-Cube's
board of directors elected to move forward with the adoption of final
resolutions regarding LSI Logic's proposed transaction. Credit Suisse First
Boston reviewed for C-Cube's board of directors its financial analysis of the
proposed exchange ratio and delivered to C-Cube's board of directors an oral
opinion, which opinion was confirmed by delivery of a written opinion dated
March 26, 2001, the date of the merger agreement, to the effect that, as of the
date of the opinion and based on and subject to the matters described in the
opinion, the exchange ratio provided for in the transaction was fair, from a
financial point of view, to the holders of C-Cube common stock (other than LSI
Logic and its affiliates). This meeting concluded with a vote of C-Cube's board
of directors in which the board unanimously approved the merger agreement,
determined that the exchange offer and the merger are fair to, and in the best
interests of, C-Cube stockholders and resolved to recommend that C-Cube
stockholders accept the exchange offer and tender their shares pursuant to the
exchange offer.

     On March 26, 2001, upon completion of all negotiations and finalization of
all agreements, the two companies executed and delivered the merger agreement
and related agreements, and LSI Logic and C-Cube issued a joint press release
announcing the transaction.

REASONS FOR THE EXCHANGE OFFER AND THE MERGER

     C-CUBE'S REASONS

     C-Cube's board of directors believes that, despite C-Cube's success to
date, increasing competition and industry consolidation would make it
increasingly important for C-Cube to grow and gain critical mass in order to
compete with larger companies with substantially greater resources and broader,
integrated

                                        38
   44

product offerings. C-Cube's management has considered a number of alternatives
for enhancing its competitive position, including a combination with a larger
company. In the industry environment referred to above, C-Cube's board of
directors identified several potential benefits for the C-Cube stockholders,
employees and customers that it believes could result from a combination with
LSI Logic. These potential benefits include, among other things:

     - providing C-Cube stockholders with shares of LSI Logic common stock in a
       tax-free exchange at a substantial premium over the prevailing market
       price for C-Cube common stock immediately prior to the announcement of
       the merger;

     - enabling the combined company to achieve synergies in a range of areas,
       particularly allowing C-Cube to take advantage of the fact that LSI Logic
       has its own manufacturing facilities while C-Cube relies entirely on
       external foundries;

     - leveraging the depth and experience of LSI Logic's management team;

     - making greater resources available for research and development, product
       distribution and service;

     - enabling the combined company to offer complementary product lines, which
       presents the opportunity to increase the breadth of products offered; and

     - dampening the magnitude of swings in operating results based on different
       demand cycles for the two companies' products.

     In the course of its deliberations during board meetings, C-Cube's board of
directors reviewed with C-Cube's management and outside advisors a number of
factors relevant to the transaction. C-Cube's board of directors considered the
following potentially positive factors, among others, in connection with its
review and analysis of the transaction. The conclusions reached by C-Cube's
board of directors with respect to each of these factors supported its
determination that the merger agreement and the transactions, including the
exchange offer and the merger, were fair to, and in the best interests of,
C-Cube and its stockholders:

     - C-Cube management's view regarding the financial condition, results of
       operations and businesses of LSI Logic and C-Cube before and after giving
       effect to the transaction based on management due diligence and publicly
       available earnings estimates and, in particular, the view that, in light
       of, among other things, market and industry conditions, the potential
       synergy and compatibility between C-Cube and LSI Logic, the complementary
       nature and lack of overlap of LSI Logic's and C-Cube's products, the
       financial strength of LSI Logic and the ability to leverage LSI Logic's
       sales network to increase sales of C-Cube's products, and the long-term
       financial condition, results of operations, prospects and competitive
       position of the combined company would be better than the long-term
       financial condition, results of operations, prospects and competitive
       position of C-Cube on a stand-alone basis;

     - current financial market conditions and historical market prices,
       volatility and trading information with respect to LSI Logic common stock
       and C-Cube common stock, as well as the greater liquidity to C-Cube
       stockholders of an investment in LSI Logic common stock compared to
       C-Cube common stock;

     - the belief that the terms of the merger agreement are reasonable;

     - the financial presentation of Credit Suisse First Boston to C-Cube's
       board of directors, including its opinion regarding the fairness, from a
       financial point of view, to the holders of C-Cube common stock (other
       than LSI Logic and its affiliates) of the exchange ratio provided for in
       the transaction, as described more fully under "Opinion of C-Cube's
       Financial Advisor" in C-Cube's Solicitation/ Recommendation Statement on
       Schedule 14D-9, which is being mailed to you together with this
       prospectus;

     - the impact of the merger on C-Cube's customers and employees; and

                                        39
   45

     - discussions with C-Cube's management, outside legal counsel and financial
       advisor regarding the results of their due diligence investigation of LSI
       Logic.

     C-Cube's board of directors also considered a number of potentially
negative factors in its deliberations concerning the merger. The potentially
negative factors considered by C-Cube's board of directors included:

     - the risk that, because the exchange ratio will not be adjusted for
       changes in the market price of either LSI Logic common stock or C-Cube
       common stock, the per share value of the consideration to be received by
       C-Cube stockholders might be less than the price per share implied by the
       exchange ratio immediately before the announcement of the proposed
       transaction due to fluctuations in the market value of LSI Logic common
       stock and C-Cube common stock;

     - the risk that the transaction might not be completed in a timely manner
       or at all;

     - the negative impact of any customer or supplier confusion after
       announcement of the proposed transaction;

     - the challenges relating to the integration of the two companies;

     - certain terms of the merger agreement and related agreements that
       prohibit C-Cube and its representatives from soliciting third party bids
       and from soliciting, initiating or encouraging third party bids, or from
       withholding, withdrawing, modifying or changing C-Cube's recommendation
       in favor of the transaction with LSI Logic, except in limited
       circumstances, which terms could reduce the likelihood that a third party
       would make a bid for C-Cube;

     - the termination fee payable by C-Cube in certain circumstances; and

     - the other risks described above in the section entitled "Risk Factors"
       starting on page 19.

     C-Cube's board of directors believed that these risks were outweighed by
the potential benefits of the transaction.

     The above discussion of the information and factors considered by C-Cube's
board of directors is not intended to be exhaustive but is believed to include
all material factors considered by the board. In view of the wide variety of
factors considered by C-Cube's board of directors, the board did not find it
practicable to quantify or otherwise assign relative weight to the specific
factors considered. In addition, C-Cube's board did not reach any specific
conclusion on each factor considered, or any aspect of any particular factor,
but conducted an overall analysis of these factors. Individual members of
C-Cube's board may have given different weight to different factors. However,
after taking into account all of the factors described above, C-Cube's board of
directors has unanimously approved the merger agreement, determined that the
exchange offer and the merger are fair to, and in the best interests of, C-Cube
stockholders and recommends that C-Cube stockholders accept the exchange offer
and tender their shares pursuant to the exchange offer.

     LSI LOGIC'S REASONS

     LSI Logic's primary reasons for seeking to complete a business combination
with C-Cube are the beliefs of LSI Logic's board of directors and management
that a business combination could result in a number of benefits, including:

     - the ability of the two companies to combine their technological resources
       to develop new products with increased functionality and bring them to
       market faster;

     - the ability of the combined company to offer complementary product lines
       and improve product offerings;

     - the ability of the combined company to commit greater resources to both
       current and emerging product development efforts and fund the future
       growth of its business;

                                        40
   46

     - the entry into a new strategic market segment for LSI Logic, with the
       potential for above average growth through an established market leader;
       and

     - the expansion of LSI Logic's business and operations in China, France,
       Japan, Korea, Taiwan and the United Kingdom.

     LSI Logic's board of directors has determined that the merger is in the
best interests of LSI Logic and its stockholders. In reaching its determination,
LSI Logic's board of directors considered a number of factors, including the
factors discussed above and listed below. The conclusions reached by LSI Logic's
board of directors with respect to the following factors supported its
determination that the transaction and the issuance of shares of LSI Logic
common stock in the exchange offer and the merger were fair to, and in the best
interests of, LSI Logic and its stockholders:

     - the judgment, advice and analysis of LSI Logic's management with respect
       to the potential strategic, financial and operational benefits of the
       transaction, including management's favorable recommendation of the
       transaction, based in part on the business, technical, financial,
       accounting and legal due diligence investigations performed with respect
       to C-Cube;

     - the results of operations and financial condition of LSI Logic and C-Cube
       and the potential accretive effect of the combination on LSI Logic common
       stock;

     - the complementary fit between LSI Logic's and C-Cube's cultures and
       market segments, which should facilitate integration of the two
       companies; and

     - the terms of the merger agreement and related agreements, including the
       exchange ratio and structure, which were considered by both the board of
       directors and management of LSI Logic to provide a fair and equitable
       basis for the transaction.

     LSI Logic's board of directors also considered a number of potentially
negative factors in its deliberations concerning the transaction. The
potentially negative factors considered by LSI Logic's board of directors
included:

     - the risk that the transaction might not be completed in a timely manner
       or at all;

     - the potential dilutive effect on the LSI Logic common stock price if
       revenue and earnings expectations of the combined company are not met;

     - the potential loss of key C-Cube employees critical to the ongoing
       success of the C-Cube products and to the successful integration of the
       LSI Logic and C-Cube product lines;

     - the general difficulties of integrating products, technologies and
       companies; and

     - the other risks and uncertainties discussed above in the section entitled
       "Risk Factors" starting on page 19.

     The above discussion of information and factors considered by LSI Logic's
board of directors is not intended to be exhaustive but is believed to include
all material factors considered by the board. In view of the wide variety of
factors considered by LSI Logic's board of directors, the board did not find it
practicable to quantify or otherwise assign relative weight to the specific
factors considered. In addition, LSI Logic's board did not reach any specific
conclusion on each factor considered, or any aspect of any particular factor,
but conducted an overall analysis of these factors.

     Individual members of LSI Logic's board may have given different weight to
different factors. However, after taking into account all of the factors
described above, LSI Logic's board of directors determined that the merger
agreement and the transaction were fair to, and in the best interests of, LSI
Logic and that LSI Logic should proceed with the transaction.

INTERESTS OF C-CUBE'S OFFICERS AND DIRECTORS IN THE TRANSACTION

     RETENTION AGREEMENTS

     C-Cube has entered into management retention agreements with certain
officers which generally provide that if a change in control of C-Cube occurs
and the officer's employment is terminated by C-Cube without "cause" or by the
officer for "good reason," within two months before or within 12 months after a
change in control of C-Cube, the officer would be entitled to:

     - salary continuation for the lesser of one year or until the officer gains
       other full-time employment;

retention agreements are hereby incorporated into this prospectus by reference.
Information regarding agreements between C-Cube and certain of its executive
officers is included in Schedule I of C-Cube's Solicitation/Recommendation
Statement on Schedule 14D-9.

     INDEMNIFICATION AND INSURANCE

     The merger agreement provides that all rights to indemnification and all
limitations on liability existing in favor of the individuals who, on or prior
to the completion of the merger were officers or directors of C-Cube and any of
its subsidiaries, as provided in C-Cube's certificate of incorporation or
bylaws, or in an agreement between one of the above individuals and C-Cube or a
subsidiary of C-Cube, as in effect as of March 26, 2001, will survive the merger
and continue in full force and effect.

     After the completion of the merger, LSI Logic is required to cause C-Cube,
as the surviving corporation in the merger, to indemnify and hold harmless the
individuals who on or before the completion of the merger were officers or
directors of C-Cube and any of its subsidiaries to the same extent as set forth
in the preceding paragraph.

     The merger agreement also provides that for six years after the completion
of the merger, C-Cube, as the surviving corporation in the merger, will provide
officers' and directors' liability insurance in respect of acts or omissions
occurring prior to the completion of the merger, covering each C-Cube officer
and director covered by C-Cube's officers' and directors' liability insurance
policy as of March 26, 2001, on terms with respect to coverage and amount at
least as favorable as those of the policy in effect on March 26, 2001. However,
C-Cube is not required to expend more than the lesser of $450,000 or 200% of
current annual premiums paid by C-Cube for the insurance each year to maintain
or procure the insurance coverage. In addition, if the amount of the annual
premiums necessary to maintain or procure the insurance coverage exceeds the
amount described in the preceding sentence, C-Cube is required to maintain or
procure, for the six-year period, the most advantageous policies of directors'
and officers' insurance obtainable for an annual premium equal to the amount
described in the preceding sentence.

MATERIAL FEDERAL INCOME TAX CONSEQUENCES

     Subject to the assumptions and limitations discussed below, in the opinion
of Cooley Godward LLP, counsel to LSI Logic, and Wilson Sonsini Goodrich &
Rosati, Professional Corporation, counsel to C-Cube, the following discussion
sets forth the material United States federal income tax considerations of the
transaction to holders of shares of C-Cube common stock who exchange their
shares of C-Cube common stock for LSI Logic shares in the exchange offer and/or
the merger. This discussion and the tax opinions described below are based on
the Code, applicable Treasury regulations, administrative interpretations and
court decisions in effect as of the date of this prospectus, all of which may
change, possibly with retroactive effect. Any of the above changes could alter
the tax consequences described in this summary and the tax opinions.

     This discussion of material federal income tax consequences of the
transaction is intended to provide only a general summary, and is not a complete
analysis or description of all potential federal income tax consequences of the
exchange offer and/or the merger. It does not address all aspects of federal
income taxation that may be important to a holder of shares of C-Cube common
stock in light of that stockholder's particular circumstances or to a
stockholder subject to special rules, such as:

     - a foreign entity or an individual stockholder who is not a citizen or
       resident of the United States;

     - a financial institution or insurance company;

     - a tax-exempt organization;

     - a dealer or broker in securities;

     - a stockholder who is subject to the alternative minimum tax provisions of
       the Code;

     - a stockholder whose shares are qualified small business stock for
       purposes of Section 1202 of the Code;

     - a stockholder who holds shares of C-Cube common stock as part of a hedge,
       appreciated financial position, straddle, constructive sale or conversion
       transaction;

     - a stockholder who acquired shares of C-Cube common stock pursuant to the
       exercise of incentive stock options or who holds shares of C-Cube common
       stock that are subject to a substantial risk of forfeiture; or

     - a stockholder who does not hold shares of C-Cube common stock as capital
       assets.

     In addition, this discussion does not address any state, local or foreign
income tax or non-income tax consequences of the exchange offer and/or the
merger or of any transactions other than the exchange offer and the merger. LSI
Logic urges holders of shares of C-Cube common stock to consult their own tax
advisors to determine the particular federal income tax or other tax
consequences to them of participation in the exchange offer and/or the merger.

     QUALIFICATION OF THE EXCHANGE OFFER AND MERGER AS A REORGANIZATION

     Although there is limited authority, the transaction will be treated for
federal income tax purposes as a reorganization within the meaning of Section
368(a) of the Code if, among other things, all of the following factual
assumptions (also referred to as the "supporting conditions") are met:

     - the exchange offer and the merger are completed under the current terms
       of the merger agreement;

     - the minimum tender condition for the exchange offer is satisfied; and

     - the merger is completed promptly after the exchange offer.

     The completion of the exchange offer is conditioned upon the receipt by LSI
Logic and C-Cube of tax opinions to the above effect from Cooley Godward LLP and
Wilson Sonsini Goodrich & Rosati, Professional Corporation, respectively. These
opinions, and the opinions contained herein, are based upon

                                        43
   49

representations and covenants made by LSI Logic and C-Cube, including
representations in certificates of officers of LSI Logic and C-Cube to be
delivered to tax counsel prior to the completion of the exchange offer, and upon
certain assumptions, including the absence of changes in facts or in law between
the date of the completion of the exchange offer and the completion of the
merger. If any of those representations, covenants or assumptions is inaccurate,
the tax consequences of the transaction could differ materially from those
summarized below. In addition, the ability to satisfy the supporting conditions,
and therefore the federal income tax consequences of the transaction, depend in
part on facts that will not be available before the completion of the merger.
There can be no assurance that the merger will be completed, or that the
supporting conditions will be satisfied. If the supporting conditions are not
satisfied, the opinions of Cooley Godward and Wilson Sonsini Goodrich & Rosati
described above may not be relied upon. Furthermore, Cooley Godward's and Wilson
Sonsini Goodrich & Rosati's opinions will neither bind the IRS nor preclude the
IRS or the courts from adopting a contrary position. C-Cube stockholders should
be aware that neither the IRS nor any court has ruled on the tax treatment of a
combination of transactions identical to the transaction and no ruling has been
or will be requested from the IRS in connection with the transaction.
Accordingly, it is possible that the exchange offer and/or the merger may not
qualify as a reorganization, and the tax consequences of the transaction could
differ materially from those summarized below. See the section entitled
"-- Federal Income Tax Consequences if the Exchange Offer and the Merger Do Not
Qualify as a Reorganization."

     Assuming that the transaction qualifies as a tax-free reorganization, for
federal income tax purposes:

     - A holder of shares of C-Cube common stock will not recognize any gain or
       loss on its exchange in the exchange offer or the merger of its shares of
       C-Cube common stock for LSI Logic shares.

     - If a holder of shares of C-Cube common stock receives cash instead of
       fractional shares of LSI Logic common stock, the stockholder will be
       required to recognize capital gain or loss, measured by the difference
       between the amount of cash received instead of that fraction of a share
       and the portion of the tax basis of that holder's shares of C-Cube common
       stock allocable to that fraction of a share. This gain or loss will be
       long-term capital gain or loss if the holder of shares of C-Cube common
       stock has held the shares of C-Cube common stock exchanged for that
       fraction of an LSI Logic share for more than one year at the time the
       shares of C-Cube common stock are accepted in the exchange offer or at
       the completion of the merger, as the case may be. The deductibility of
       capital losses is subject to limitations for both individuals and
       corporations.

     - A holder of shares of C-Cube common stock will have a tax basis in the
       LSI Logic shares received in the exchange offer or the merger equal to
       (1) the tax basis in the shares of C-Cube common stock surrendered by
       that stockholder in the exchange offer or the merger, reduced by (2) any
       tax basis in the shares of C-Cube common stock that is allocable to a
       fraction of an LSI Logic share for which cash is received.

     - The holding period for LSI Logic shares received in exchange for shares
       of C-Cube common stock in the exchange offer or the merger will include
       the holding period for shares of C-Cube common stock surrendered in the
       exchange offer or the merger.

     - Under specified circumstances, holders of shares of C-Cube common stock
       may be entitled to appraisal rights in connection with the merger. See
       the section entitled "The Transaction -- Appraisal Rights" below. If
       appraisal rights are available and a holder of shares of C-Cube common
       stock receives cash pursuant to the exercise of appraisal rights, the
       stockholder will recognize capital gain or loss, measured by the
       difference between the amount realized and the holder's tax basis in the
       shares of C-Cube common stock. Holders of shares of C-Cube common stock
       that exercise appraisal rights are urged to consult their own tax
       advisors.

     - C-Cube will not recognize gain or loss as a result of the transaction.

                                        44
   50

     FEDERAL INCOME TAX CONSEQUENCES IF THE EXCHANGE OFFER AND THE MERGER DO NOT
     QUALIFY AS A REORGANIZATION

     The tax consequences described above are based on factual assumptions,
representations and covenants, including the satisfaction of the supporting
conditions. If any of those factual assumptions, representations or covenants
are not satisfied or observed, or in the event of a contrary ruling by the IRS
or a court, the federal income tax consequences of the transaction to holders of
shares of C-Cube common stock could differ materially from those summarized
above in the section entitled "-- Qualification of the Exchange Offer and the
Merger as a Reorganization." In that event, exchanges by C-Cube stockholders
pursuant to the exchange offer and/or the merger could be taxable transactions
for federal income tax purposes depending on the particular facts surrounding
the exchange offer and/or the merger, some of which may not be known before the
completion of the merger or later points in time.

     If the exchange offer and/or the merger is taxable, each C-Cube stockholder
participating in the exchange offer and/or the merger, as applicable, will
recognize capital gain or loss, measured by the difference between the fair
market value of the LSI Logic shares (together with any cash instead of
fractional shares of LSI Logic common stock) received by the stockholder and the
stockholder's tax basis in the shares of C-Cube common stock surrendered. This
gain or loss will be long-term capital gain or loss if the stockholder had held
the shares of C-Cube common stock for more than one year at the time the shares
of C-Cube common stock are accepted in the exchange offer or at the completion
of the merger, as applicable.

     FEDERAL INCOME TAX CONSEQUENCES IF THE MERGER IS NOT COMPLETED

     No opinion has been given concerning any tax consequences of the exchange
offer if the merger is not completed, or if the merger is not completed promptly
after the exchange offer. Except as described under this heading, if the merger
is not completed, exchanges pursuant to the exchange offer generally will be
taxable transactions for federal income tax purposes with the consequences
described above in the section entitled "-- Federal Income Tax Consequences if
the Exchange Offer and the Merger Do Not Qualify as a Reorganization."

     Even if the merger is not completed, the exchange offer will still be
treated for federal income tax purposes as a reorganization within the meaning
of Section 368(a) of the Code so long as the following factual assumptions are
met:

     - in general, LSI Logic must acquire at least 80% of the shares of C-Cube
       common stock in the exchange offer;

     - any acquisition of additional shares of C-Cube common stock from other
       stockholders that LSI Logic may decide to effect must not be for
       consideration other than LSI Logic voting stock; and

     - the representations and covenants made by LSI Logic and C-Cube to Cooley
       Godward and Wilson Sonsini Goodrich & Rosati must remain effective.

     Whether these factual assumptions will be satisfied will not be known at
the time of the exchange offer and there can be no assurances that the factual
assumptions will be satisfied.

     LSI Logic urges each holder of shares of C-Cube common stock to consult his
or her own tax advisor to determine the particular United States federal, state
or local or foreign income or other tax consequences of participation in the
exchange offer and/or the merger.

     FEDERAL BACKUP WITHHOLDING; REPORTING

     To prevent backup federal income tax withholding with respect to cash, if
any, received pursuant to the exchange offer and/or the merger, you must either
provide the Exchange Agent with your correct taxpayer identification number and
certify whether you are subject to backup withholding of federal income tax by
completing the substitute Form W-9 included in the letter of transmittal or
establish a basis for exemption from backup withholding. Some stockholders
(including, among others, all corporations and
                                        45
   51

some foreign individuals) are not subject to these backup withholding and
reporting requirements. In order for a foreign person to qualify as an exempt
recipient, the stockholder must generally submit a Form W-8BEN, W-8ECI, W-8EXP
or W-8IMY, as appropriate, signed under penalties of perjury, attesting to that
person's exempt status. C-Cube stockholders who fail to provide their correct
taxpayer identification numbers and the appropriate certifications or to
establish an exemption as described above will be subject to backup withholding
of 31% on cash amounts received in the exchange offer and/or the merger and may
be subject to a $50 penalty imposed by the IRS. If withholding is made and
results in an overpayment of taxes, a refund may be obtained. Cash amounts paid
pursuant to the exchange offer and/or the merger will be reported to the extent
required by the Code to C-Cube stockholders and the IRS.

     Each C-Cube stockholder who receives LSI Logic's common shares in the
exchange offer and/or the merger is required to file a statement with his, her
or its federal income tax return setting forth the stockholder's basis in the
shares of C-Cube common stock surrendered and the fair market value of LSI
Logic's common shares and the proceeds from the cash in lieu of fractional
shares received in the exchange offer and the merger and is required to retain
permanent records of these facts relating to the transaction.

ACCOUNTING TREATMENT

     The transaction described in this prospectus will be accounted for as a
"purchase," as that term is used under generally accepted accounting principles,
commonly referred to as "GAAP," for accounting and financial reporting purposes.
C-Cube will be treated as the acquired corporation for these purposes. C-Cube's
assets, liabilities and other items will be adjusted to their estimated fair
value at the completion of the merger and combined with the historical book
values of the assets and liabilities of LSI Logic. Applicable income tax effects
of these adjustments will be included as a component of the combined company's
deferred tax asset or liability. The difference between the estimated fair value
of the assets, liabilities and other items (adjusted as discussed above) and the
purchase price will be recorded as an intangible asset and amortized against the
combined company's earnings over six years following completion of the merger.
For further information concerning the amount of goodwill or other intangibles
to be recorded in connection with the merger and the amortization of that
goodwill, see the section entitled "Notes to Unaudited Pro Forma Combined
Condensed Financial Statements" on page 95.

     On February 14, 2001, the Financial Accounting Standards Board (FASB)
issued an exposure draft for public comment which proposes changing the method
of accounting for goodwill in a purchase transaction from capitalization and
amortization against earnings to capitalization and periodic evaluation for
impairment. If this change were adopted by the FASB, unamortized goodwill
resulting from this transaction would be reported as an asset and not amortized
against earnings unless it became impaired. The public comment period ended on
March 16, 2001 and the FASB proposes to make this change effective July 2001;
however, there can be no assurance that the FASB will ever adopt this change or
that any final standard will become effective in July 2001.

REGULATORY APPROVALS

     Other than clearance under the antitrust laws applicable to the transaction
which are described below, the Securities and Exchange Commission declaring the
registration statement on Form S-4 relating to this transaction effective and
the filing of a certificate of merger under Delaware law with respect to the
merger, LSI Logic does not believe that any additional material governmental
filings are required with respect to the transaction.

     Under the HSR Act, the transaction may not be completed until LSI Logic and
C-Cube each notify and furnish information to the Federal Trade Commission and
the Antitrust Division of the United States Department of Justice and specified
waiting period requirements have been satisfied. LSI Logic and C-Cube agreed,
pursuant to the merger agreement, to use commercially reasonable efforts to take
or cause to be taken all actions necessary to obtain any clearance, waiver,
approval or authorization relating to the HSR Act that is necessary to enable
LSI Logic and C-Cube to complete the transaction. The notifications

                                        46
   52

required under the HSR Act to the Federal Trade Commission and the Antitrust
Division of the United States Department of Justice were filed on April 10,
2001, and the waiting period under the HSR Act will expire on May 10, 2001,
unless otherwise extended or terminated.

     At any time before or after the completion of the exchange offer or the
merger, either the Antitrust Division of the United States Department of Justice
or the Federal Trade Commission could take any action under United States
antitrust laws that it deems necessary or desirable, including seeking to enjoin
the completion of the exchange offer or the merger or seeking the divestiture of
substantial assets of LSI Logic or C-Cube. Private parties and state attorneys
general may also bring actions under United States antitrust laws depending on
the circumstances. Although we believe that neither the exchange offer nor the
merger raises concerns under U.S. antitrust laws, we can give no assurance that
a challenge to the exchange offer or the merger on antitrust grounds will not be
made or, if a challenge is made, that it would not be successful.

     LSI Logic and C-Cube also conduct operations internationally, where other
antitrust-related regulatory filings or approvals are likely to be required in
connection with the completion of the exchange offer and the merger. LSI Logic
and C-Cube anticipate that antitrust-related regulatory filings will be
submitted in connection with the completion of the transaction in Germany, Japan
and such other foreign jurisdictions where filings are determined to be
necessary. It is expected that the waiting periods under the relevant foreign
antitrust laws will expire in May 2001, unless otherwise extended or terminated.
The foreign antitrust authorities or private parties could also take any action
available to them under the relevant foreign antitrust laws that they deem
necessary or desirable, including seeking to enjoin the completion of the
exchange offer or the merger or seeking the divestiture of substantial assets of
LSI Logic or C-Cube. Although we believe that neither the exchange offer nor the
merger raises concerns under foreign antitrust laws, we can give no assurance
that a challenge to the exchange offer or the merger on antitrust grounds will
not be made or, if a challenge is made, that it would not be successful.

APPROVAL OF THE MERGER

     Under Section 251 of the Delaware General Corporation Law, the approval of
the board of directors of a company and the affirmative vote of the holders of
at least a majority of its outstanding shares on the record date for such
meeting are required to approve a merger and adopt a merger agreement. C-Cube's
board of directors has previously approved the merger.

     If, after completion of the exchange offer, LSI Logic owns more than 50%
but less than 90% of the outstanding shares of C-Cube common stock, it would
complete the acquisition of the remaining outstanding shares of C-Cube common
stock through a vote of C-Cube stockholders with respect to the merger. Since
LSI Logic will own a majority of the shares of C-Cube common stock on the record
date, it would have a sufficient number of shares of C-Cube common stock to
approve the merger without the affirmative vote of any other holder of shares of
C-Cube common stock and, therefore, approval of the merger by C-Cube
stockholders will be assured. Completion of the transaction in this manner is
referred to in this prospectus as a "long-form" merger.

     Under Section 253 of the Delaware General Corporation Law, a merger can
occur without a vote of C-Cube stockholders, referred to as a "short-form
merger," if, after completion of the exchange offer, as it may be extended and
including any subsequent offering period, LSI Logic were to own at least 90% of
the outstanding shares of C-Cube common stock. If, after completion of the
exchange offer, as it may be extended and including any subsequent offering
period, LSI Logic owns at least 90% of the outstanding shares of C-Cube common
stock, LSI Logic would complete the acquisition of the remaining outstanding
shares of C-Cube common stock by completing a short-form merger.

APPRAISAL RIGHTS

     C-Cube stockholders do not have appraisal rights in connection with the
exchange offer.

     If LSI Logic completes the exchange offer but, upon completion of the
exchange offer, as it may be extended and including any subsequent offering
period, it owns less than 90% of the outstanding shares of C-Cube common stock,
LSI Logic has agreed to effect a long-form merger, as described above. C-Cube

                                        47
   53

stockholders who have not exchanged their shares of C-Cube common stock in the
exchange offer will not have appraisal rights in connection with a long-form
merger.

     If LSI Logic completes the exchange offer and, upon completion of the
exchange offer, as it may be extended and including any subsequent offering
period, it owns at least 90% of the outstanding shares of C-Cube common stock,
LSI Logic has agreed to effect a short-form merger (as described above). C-Cube
stockholders at the time of a short-form merger will have the right under
Section 262 of the Delaware General Corporation Law to dissent and demand
appraisal of their shares of C-Cube common stock. Under Section 262, dissenting
stockholders who comply with the applicable statutory procedures will be
entitled to receive a judicial determination of the fair value of their shares
of C-Cube common stock (exclusive of any element of value arising from the
accomplishment or expectation of the merger) and to receive payment of this fair
value in cash, together with a fair rate of interest, if any. In Cede & Co. and
Cinerama, Inc. v. Technicolor, Inc., the Supreme Court of the State of Delaware
construed Section 262 of the Delaware General Corporation Law and held that the
"accomplishment or expectation" exclusion from the calculation of fair value
described in the preceding sentence is narrow and is designed to eliminate use
of pro forma data and projections of a speculative variety relating to the
completion of a merger. The court held that it is appropriate to include in the
calculation of fair value any known elements of value. LSI Logic cannot assure
you what methodology a court would use to determine fair value or how a court
would select which of the elements of value that are to be included in its
determination.

POSSIBLE EFFECTS OF THE EXCHANGE OFFER

     REDUCED LIQUIDITY OF C-CUBE COMMON STOCK; POSSIBLY NO LONGER INCLUDED FOR
     QUOTATION

     The tender and exchange of shares of C-Cube common stock pursuant to the
exchange offer will reduce the number of holders of shares of C-Cube common
stock and the number of shares of C-Cube common stock that might otherwise trade
publicly and could adversely affect the liquidity and market value of the
remaining shares of C-Cube common stock held by the public. Shares of C-Cube
common stock are included for listing and principally traded on the Nasdaq
National Market. Depending on the number of shares of C-Cube common stock
acquired pursuant to the exchange offer, following completion of the exchange
offer, shares of C-Cube common stock may no longer meet the requirements of the
Nasdaq National Market for continued listing. The requirements for continued
inclusion in the Nasdaq National Market, among other things, require that an
issuer have either:

     - at least 750,000 publicly held shares, held by at least 400 stockholders
       of round lots, with a market value of at least $5 million and net
       tangible assets of at least $4 million and at least two registered and
       active market makers for the shares; or

     - at least 1,100,000 publicly held shares, held by at least 400
       stockholders of round lots, with a market value of at least $15 million
       and at least four registered and active market markers, and either:

      - a market capitalization of at least $50 million; or

      - total assets and total revenue of at least $50 million each for the most
        recently completed fiscal year or two of the last three most recently
        completed fiscal years.

     Even if the requirements for continued inclusion in the Nasdaq National
Market are not satisfied, the shares might nevertheless continue to be included
in a different tier of Nasdaq with quotations published in the Nasdaq
"additional list" or in one of the "local lists," but if the number of holders
of the shares were to fall below 300, the number of publicly held shares were to
fall below 500,000 or there were not at least two registered and active market
makers for the shares, applicable Nasdaq rules provide that the shares would no
longer be "qualified" for Nasdaq reporting and Nasdaq would cease to provide any
quotations. Shares held directly or indirectly by directors, officers or
beneficial owners of more than 10% of the shares are not considered as being
publicly held for this purpose. If, following the completion of the exchange
offer, the shares of C-Cube no longer meet the requirements for continued
inclusion in the

                                        48
   54

Nasdaq National Market or in any other tier of Nasdaq and the shares were no
longer included in the Nasdaq National Market or in any other tier of Nasdaq,
the market for shares of C-Cube common stock could be adversely affected.

     If the shares of C-Cube common stock no longer meet the requirements for
continued inclusion in any tier of the Nasdaq, it is possible that the shares
would continue to trade in the over-the-counter market and that price quotations
would be reported by other sources. The extent of the public market for the
shares of C-Cube common stock and the availability of quotations for shares of
C-Cube common stock would, however, depend upon the number of holders of shares
remaining at that time, the interest in maintaining a market in shares of C-Cube
common stock on the part of securities firms, the possible termination of
registration of the shares under the Securities Exchange Act of 1934, as
described below, and other factors. LSI Logic cannot predict whether the
reduction in the number of shares of C-Cube common stock that might otherwise
trade publicly would have an adverse or beneficial effect on the market price
for, or marketability of, the shares of C-Cube common stock.

     According to C-Cube, there were, as of April 10, 2001, approximately
50,368,014 shares of C-Cube common stock outstanding.

     STATUS AS "MARGIN SECURITIES"

     The shares of C-Cube common stock are presently "margin securities" under
the regulations of the Federal Reserve Board, which has the effect, among other
things, of allowing brokers to extend credit on the collateral of shares of
C-Cube common stock. Depending on factors similar to those described above with
respect to market quotations, following completion of the exchange offer, the
shares of C-Cube common stock may no longer constitute "margin securities" for
the purposes of the Federal Reserve Board's margin regulations, in which event
the shares of C-Cube common stock would not be eligible as collateral for margin
loans made by brokers.

     REGISTRATION UNDER THE SECURITIES EXCHANGE ACT OF 1934

     Shares of C-Cube common stock are currently registered under the Securities
Exchange Act of 1934. C-Cube can terminate that registration upon application to
the Securities and Exchange Commission if the outstanding shares are not listed
on a national securities exchange or listed on an automated inter-dealer
quotation system, or if there are fewer than 300 holders of record of shares of
C-Cube common stock. Termination of registration of the shares of C-Cube common
stock under the Securities Exchange Act of 1934 would reduce the information
that C-Cube must furnish to its stockholders and to the Securities and Exchange
Commission and would make certain provisions of the Securities Exchange Act of
1934, such as the short-swing profit recovery provisions of Section 16(b) and
the requirement of furnishing a proxy statement in connection with stockholders
meetings pursuant to Section 14(a) and the related requirement of furnishing an
annual report to stockholders, no longer applicable with respect to shares of
C-Cube common stock. In addition, if shares of C-Cube common stock are no longer
registered under the Securities Exchange Act of 1934, the requirements of Rule
13e-3 under the Securities Exchange Act of 1934 with respect to "going-private"
transactions would no longer be applicable to C-Cube. Furthermore, the ability
of "affiliates" of C-Cube and persons holding "restricted securities" of C-Cube
to dispose of these securities pursuant to Rule 144 under the Securities Act of
1933 may be impaired or eliminated. If registration of the shares under the
Securities Exchange Act of 1934 were terminated, they would no longer be
eligible for Nasdaq reporting or for continued inclusion on the Federal Reserve
Board's list of "margin securities."

RELATIONSHIPS BETWEEN LSI LOGIC AND C-CUBE

     Except for the Stockholder Agreements or as otherwise described in this
prospectus, neither LSI Logic nor, to the best of LSI Logic's knowledge, any of
its directors, executive officers or other affiliates has any contract,
arrangement, understanding or relationship with any other person with respect to
any securities of C-Cube, including, but not limited to, any contract,
arrangement, understanding or

                                        49
   55

relationship concerning the transfer or the voting of any securities, joint
ventures, loan or option arrangements, puts or calls, guaranties of loans,
guaranties against loss or the giving or withholding of proxies. Except as
described in this prospectus, there have been no contacts, negotiations or
transactions since January 1, 1996, between LSI Logic or, to the best of LSI
Logic's knowledge, any of its directors, executive officers or other affiliates
on the one hand, and C-Cube or its affiliates, on the other hand, concerning a
merger, consolidation or acquisition, a tender offer or other acquisition of
securities, an election of directors, or a sale or other transfer of a material
amount of assets. Neither LSI Logic nor, to the best of LSI Logic's knowledge,
any of its directors, executive officers or other affiliates has since January
1, 1996 had any transaction with C-Cube or any of its officers, directors or
affiliates that would require disclosure under the rules and regulations of the
Securities and Exchange Commission applicable to the exchange offer. It should
be noted, however, that:

     - C-Cube currently leases certain office space from LSI Logic, located at
       1855 Barber Lane in Milpitas, California.

     - Wilson Sonsini Goodrich & Rosati, Professional Corporation, incorporated
       LSI Logic in 1980 and has acted as their outside legal counsel since that
       time. Larry W. Sonsini has been a member of LSI Logic's board of
       directors since 2000. In addition, Mr. Sonsini has been a member of the
       law firm of Wilson Sonsini Goodrich & Rosati since 1969, where he
       currently serves as the Chairman of the Board and Chief Executive
       Officer. Wilson Sonsini Goodrich & Rosati has also represented C-Cube in
       general corporate matters and in various transactions since its initial
       public offering in 1994. Because of Mr. Sonsini's personal involvement in
       the recent transaction between Harmonic Inc. and C-Cube, among other
       things, Mr. Sonsini and Mr. Corrigan believed it to be in the best
       interests of all parties involved for Wilson Sonsini Goodrich & Rosati to
       act as outside legal counsel to C-Cube for this transaction and for LSI
       Logic to seek separate outside legal counsel. Recognizing the potential
       conflicts of interest posed, both C-Cube and LSI Logic executed
       appropriate conflict waivers. In addition, since the date of engagement
       as outside legal counsel by C-Cube in this transaction, Mr. Sonsini has
       not participated as a member of LSI Logic's board of directors, or
       otherwise on behalf of LSI Logic, in any discussion, negotiation or vote
       regarding the exchange offer or the merger.

     Neither LSI Logic nor, to the best of LSI Logic's knowledge, any of its
directors, executive officers or other affiliates beneficially owns or has any
right to acquire, directly or indirectly, any shares of C-Cube common stock,
except Mr. Corrigan, who currently holds 627 shares of C-Cube common stock in a
family trust fund.

     Neither LSI Logic nor, to the best of LSI Logic's knowledge, any of its
directors, executive officers or other affiliates has effected any transaction
in shares of C-Cube common stock during the past 60 days.

FEES AND EXPENSES

     LSI Logic has retained D.F. King & Co. to act as Information Agent in

Information Agent reasonable and customary compensation for these services in
addition to reimbursing the Information Agent for its reasonable out-of-pocket
expenses. LSI Logic has agreed to indemnify the Information Agent against
certain liabilities and expenses in connection with the exchange offer,

                     CERTAIN TERMS OF THE MERGER AGREEMENT

     The following description of the merger agreement describes the material
terms of the merger agreement. The complete text of the merger agreement is
attached as Annex A to this prospectus and is incorporated into this prospectus
by reference. All stockholders are urged to read the entire merger agreement
carefully.

THE EXCHANGE OFFER

     GENERALLY

     Under the terms of the merger agreement, LSI Logic has commenced an
exchange offer for all outstanding shares of C-Cube common stock. In the
exchange offer, LSI Logic is offering to exchange 0.79 of a share of LSI Logic
common stock for each share of C-Cube common stock that is validly tendered and
not properly withdrawn. The initial expiration date of the exchange offer is May
10, 2001, the twentieth business day following its commencement.

     MANDATORY EXTENSIONS OF THE EXCHANGE OFFER

     If any condition to the exchange offer is not satisfied or, if permissible,
waived on any scheduled expiration date of the exchange offer, LSI Logic is
required to extend the expiration date of the exchange offer for successive
extension periods of not more than 10 business days per extension, until all
conditions to the exchange offer are satisfied or, if permissible, waived, or
until the merger agreement is terminated in accordance with its terms.

     OPTIONAL EXTENSIONS OF THE EXCHANGE OFFER

     LSI Logic has the right to extend the exchange offer to the extent required
by the applicable rules and regulations of the Securities and Exchange
Commission or The New York Stock Exchange.

     SUBSEQUENT OFFERING PERIOD

     LSI Logic may elect to provide subsequent offering periods of three to 20
business days after the acceptance of shares of C-Cube common stock in the
exchange offer if the requirements of Rule 14d-11 under the Securities Exchange
Act of 1934, have been met. You will not have the right to withdraw any shares
of C-Cube common stock that you tender during any subsequent offering period.
LSI Logic is required to accept for exchange, and to deliver shares of LSI Logic
common stock in exchange for, shares of C-Cube common stock that are validly
tendered and not properly withdrawn, promptly after the shares of C-Cube common
stock are tendered during any subsequent offering period. If LSI Logic elects to
provide a subsequent offering period, it is required to make a public
announcement to that effect no later than 9:00 a.m., New York time, on the next
business day after the previously scheduled expiration date of the exchange
offer.

     PROMPT PAYMENT FOR SHARES OF C-CUBE COMMON STOCK IN THE EXCHANGE OFFER

     Subject to the terms of the exchange offer and the merger agreement and the
satisfaction (or waiver to the extent permitted) of the conditions to the
exchange offer, LSI Logic is required to accept for exchange all shares of
C-Cube common stock validly tendered and not properly withdrawn pursuant to the
exchange offer promptly after the applicable expiration date of the exchange
offer, as it may be extended pursuant to the merger agreement, and is required
to exchange all accepted shares of C-Cube common stock promptly after
acceptance.

     LSI Logic will not issue certificates representing fractional shares of its
common stock in the exchange offer. Instead, each tendering stockholder who
would otherwise be entitled to a fractional share (after aggregating all
fractional shares of LSI Logic common stock that otherwise would be received by
the stockholder) will receive cash (rounded up to the nearest whole cent),
without interest, equal to the price obtained by multiplying 0.79 by the average
closing sale price of one share of LSI Logic common

                                        52
   58

stock on The New York Stock Exchange during the 10 trading days ending on the
trading day immediately prior to the expiration of the exchange offer, as it may
be extended pursuant to the merger agreement.

COMPOSITION OF C-CUBE'S BOARD OF DIRECTORS AFTER THE EXCHANGE OFFER

     Upon the acceptance for payment of shares of C-Cube common stock pursuant
to the exchange offer, LSI Logic will be entitled to designate a number of
directors of C-Cube, rounded up to the next whole number, that equals:

     - the total number of directors on C-Cube's board of directors (giving
       effect to any increase in the size of C-Cube's board of directors
       effected in accordance with the merger agreement);

       multiplied by,

     - the percentage that the number of shares of C-Cube common stock owned by
       LSI Logic (including shares of C-Cube common stock accepted for payment)
       bears to the total number of shares of C-Cube common stock then
       outstanding.

     Under the terms of the merger agreement, C-Cube has agreed to take all
action reasonably necessary to cause LSI Logic's designees to be elected or
appointed to C-Cube's board of directors, including, at the option of LSI Logic,
increasing the number of directors or seeking and accepting resignations of
incumbent directors, or both. Until the completion of the merger, C-Cube's board
of directors is required to include at least two members (the "continuing
directors") who were directors of C-Cube prior to the completion of the exchange
offer. If, at any time prior to the completion of the merger, the number of
continuing directors is reduced to fewer than two for any reason, the remaining
and departing continuing directors will be entitled to designate a person to
fill the vacancy.

     The merger agreement provides that if LSI Logic's designees are elected to
C-Cube's board of directors prior to the completion of the merger, the
affirmative vote of a majority of the continuing directors will be required for
C-Cube to:

     - amend or terminate the merger agreement or agree or consent to any
       amendment or termination of the merger agreement;

     - waive any of C-Cube's rights, benefits or remedies under the merger
       agreement;

     - extend the time for performance of LSI Logic's obligations under the
       merger agreement; or

     - approve any other action by C-Cube that is reasonably likely to adversely
       affect the interests of the C-Cube stockholders (other than LSI Logic,
       Clover Acquisition Corp. and their affiliates) with respect to the
       transactions contemplated by the merger agreement.

THE MERGER

     GENERALLY

     The merger agreement provides that following completion of the exchange
offer, Clover Acquisition Corp. will be merged into C-Cube. Upon completion of
the merger, C-Cube will continue as the "surviving corporation" and will be a
wholly owned subsidiary of LSI Logic.

     THE COMPLETION OF THE MERGER

     The merger will be completed and become effective when the certificate of
merger is filed with the Secretary of State of the State of Delaware. LSI Logic
and C-Cube anticipate that the merger will be completed no later than the second
business day after all of the conditions to the merger contained in the merger
agreement are satisfied or, where permissible, waived.

                                        53
   59

     MANNER AND BASIS OF CONVERTING SHARES OF C-CUBE COMMON STOCK IN THE MERGER

     Under the terms of the merger agreement, upon completion of the merger,
each share of C-Cube common stock will be converted into the right to receive
0.79 of a share of LSI Logic common stock, the same per share consideration
issued to holders of shares of C-Cube common stock whose shares of C-Cube common
stock were accepted for exchange in the exchange offer. The merger consideration
will not be payable in respect of shares of C-Cube common stock held by C-Cube
as treasury stock immediately prior to completion of the merger, shares of
C-Cube common stock owned by LSI Logic immediately prior to the completion of
the merger or shares of C-Cube common stock for which appraisal rights are
exercised under Delaware law.

     LSI Logic will not issue certificates representing fractional shares of its
common stock in the merger. Instead, each stockholder who would otherwise be
entitled to a fractional share (after aggregating all fractional shares of LSI
Logic common stock that otherwise would be received by the stockholder) will
receive cash (rounded to the nearest whole cent), without interest, equal to the
price obtained by multiplying 0.79 by the average closing sale price of one
share of LSI Logic common stock on The New York Stock Exchange during the 10
trading days ending on the trading day immediately prior to the date of
completion of the merger.

     The merger agreement contemplates that, no later than 10 business days
after the date of completion of the merger, the Exchange Agent will mail to each
record holder of a certificate or certificates, that, immediately prior to the
completion of the merger represented outstanding shares of C-Cube common stock,
a letter of transmittal and instructions for use in exchanging C-Cube common
stock certificates for LSI Logic common stock certificates and cash for any
fractional share. In addition, the merger agreement contemplates that, within 10
business days after the Exchange Agent receives back from the record holder of
shares of C-Cube common stock the C-Cube common stock certificate, the letter of
transmittal and any other documents that are required by the letter of
transmittal, the Exchange Agent will mail to the record holder a certificate or
certificates representing the appropriate number of shares of LSI Logic common
stock and an amount of cash for any fractional share. Additionally, record
holders of C-Cube common stock certificates may, at their option after the
completion of the merger, physically surrender their C-Cube common stock
certificates in person at the offices of the Exchange Agent listed on the back
of this prospectus, for LSI Logic common stock certificates and cash for any
fractional share.

     After the completion of the merger, until it is surrendered and exchanged,
each certificate that previously evidenced C-Cube common stock will be deemed to
evidence the right to receive shares of LSI Logic common stock and the right to
receive cash instead of fractional shares of LSI Logic common stock. LSI Logic
will not pay dividends or other distributions on any shares of LSI Logic common
stock to be issued in exchange for any C-Cube common stock certificate that is
not surrendered until the C-Cube common stock certificate is properly
surrendered, as provided in the merger agreement.

ASSUMPTION OF C-CUBE STOCK OPTIONS AND WARRANT

     C-CUBE STOCK OPTIONS

     Under the terms of the merger agreement, upon the completion of the merger,
LSI Logic has agreed to assume each outstanding option to purchase or otherwise
acquire shares of C-Cube common stock, also referred to as a "C-Cube stock
option," that has been issued pursuant to C-Cube's 2000 Stock Plan, Director
Stock Option Plan or otherwise, on the same terms and conditions as were
applicable to the C-Cube stock option prior to the completion of the merger
(including any vesting schedule or repurchase rights). LSI Logic has agreed to
make each C-Cube stock option that is assumed by LSI Logic exercisable for the
number of shares of LSI Logic common stock equal to the product of the number of
shares of C-Cube common stock that were issuable upon the exercise of the C-Cube
stock option immediately prior to the completion of the merger, multiplied by
0.79 (rounded down to the nearest whole number of shares of LSI Logic common
stock). In addition, LSI Logic has agreed to set the exercise price per share
for shares of LSI Logic common stock issuable under each assumed C-Cube stock
option

                                        54
   60

to be at the per share exercise price at which the C-Cube stock option was
exercisable immediately prior to the completion of the merger, divided by 0.79
(rounded up to the nearest whole cent).

     LSI Logic has agreed to file a registration statement on Form S-8 with
respect to the shares of LSI Logic common stock subject to the assumed C-Cube
stock options no later than five business days after the completion of the
merger. LSI Logic has agreed to use its commercially reasonable efforts to
maintain the effectiveness of the registration statement on Form S-8 for so long
as any assumed C-Cube stock options remain outstanding.

     Shares of LSI Logic common stock that are issued upon conversion of shares
of C-Cube common stock that, immediately prior to the completion of the merger,
are unvested or are subject to a repurchase option, risk of forfeiture or other
condition, will continue to be unvested or subject to the same option, risk or
other condition after the completion of the merger unless the relevant agreement
provides that the option, risk or condition will be altered or will terminate
upon completion of the merger.

     C-CUBE WARRANT

     Pursuant to the terms of the merger agreement, upon completion of the
merger, LSI Logic has agreed to assume the outstanding warrant issued by C-Cube
to Thomson Multimedia S.A. on the same terms and conditions as were applicable
to the warrant prior to the completion of the merger (including the vesting
schedule applicable to the warrant). LSI Logic has agreed to make the warrant
exercisable for the number of shares of LSI Logic common stock equal to the
product of the number of shares of C-Cube common stock that were issuable upon
the exercise of the warrant immediately prior to the completion of the merger,
multiplied by 0.79 (rounded up to the nearest whole number of shares of LSI
Logic common stock). In addition, LSI Logic has agreed to set the exercise price
per share for shares of LSI Logic common stock issuable under the warrant to be
at the per share exercise price at which the warrant was exercisable immediately
prior to the completion of the merger, divided by 0.79 (rounded up to the
nearest whole cent).

TERMINATION OF C-CUBE EMPLOYEE STOCK PURCHASE PLAN

     The merger agreement provides that C-Cube will terminate C-Cube's employee
stock purchase plan prior to the completion of the merger. Subject to the terms
of the merger agreement, the last business day prior to, or if administratively
advisable, the last payroll date of C-Cube immediately prior to, the completion
of the merger will be treated as the last day of any offering period then
underway under the employee stock purchase plan. Pro-rata adjustments may be
required under the employee stock purchase plan to reflect this shortened
offering period, but the offering period will otherwise be treated as a fully
effective and completed offering period for all purposes of the employee stock
purchase plan. The change in the offering period described above is conditioned
upon the completion of the merger.

     Pursuant to the terms of the merger agreement, LSI Logic has agreed that,
after the completion of the merger, employees of C-Cube who become employees of
LSI Logic or any of its subsidiaries will be able to participate in LSI Logic's
employee stock purchase plan. LSI Logic has also agreed to create a special
offering period under its employee stock purchase plan so that employees of
C-Cube who become employees of LSI Logic or any of its subsidiaries can
participate in LSI Logic's employee stock purchase plan within 15 days after
completion of the merger.

REPRESENTATIONS AND WARRANTIES

     The merger agreement contains a number of customary representations and
warranties relating to, among other things, certain aspects of the respective
businesses and assets of each of the parties and their ability to complete the
transaction. The representations and warranties of each party will expire upon
completion of the merger.

                                        55
   61

CONDUCT OF C-CUBE'S BUSINESS PRIOR TO COMPLETION OF THE EXCHANGE OFFER

     The merger agreement contemplates that, until the acceptance for exchange
of shares of C-Cube common stock pursuant to the exchange offer, each of C-Cube
and its subsidiaries will conduct its operations in the ordinary course of
business consistent with past practice and will use commercially reasonable
efforts to preserve intact its present business organization and its
relationships with customers, suppliers and others having business relationships
with it. The merger agreement also contemplates that, until shares of C-Cube
common stock are accepted for exchange pursuant to the exchange offer, neither
C-Cube nor any of its subsidiaries will, without the prior written consent of
LSI Logic (which LSI Logic has agreed not to unreasonably withhold):

     - declare, set aside or pay any dividend or other distribution with respect
       to any shares of capital stock of C-Cube or any subsidiary of C-Cube
       (other than dividends or other distributions in the ordinary course of
       business consistent with past practice from a wholly owned subsidiary of
       C-Cube to C-Cube), or repurchase, redeem or acquire any outstanding
       shares of capital stock or other equity securities of, or other ownership
       interests in, C-Cube or any subsidiary of C-Cube;

       with past practice;

     - enter into or amend any employment, deferred compensation or other
       similar contract with any director, officer or employee of C-Cube or any

       other than pursuant to C-Cube stock options outstanding as of the date of
       the merger agreement, the warrant issued to Thomson Multimedia S.A. or
       the terms of C-Cube's employee stock purchase plan;

     - amend or waive any of its rights under, or accelerate the vesting under,

       restricted stock purchase agreement, or otherwise modify any of the terms
       of any outstanding option, warrant or other security or any related
       agreement;

       behalf of C-Cube after the date of the merger agreement and prior to the
       first acceptance for exchange of shares of C-Cube common stock pursuant
       to the exchange offer, do not exceed C-Cube's forecasted capital
       expenditures for such period as previously provided to LSI Logic;

     - commence or settle any action, suit or proceeding except for actions,
       suits or proceedings involving only the receipt of money by C-Cube or any
       subsidiary of C-Cube or the payment by C-Cube or any subsidiary of C-Cube
       of no more than $250,000 in the aggregate; or

     - authorize, commit or agree to take any of the above actions except as
       otherwise permitted by the merger agreement.

COMMERCIALLY REASONABLE EFFORTS TO COMPLETE THE TRANSACTION

     LSI Logic and C-Cube are required to make all filings required under
antitrust laws applicable to the transaction and to use commercially reasonable
efforts to take all actions necessary to complete the transaction.

LIMITATION ON C-CUBE'S ABILITY TO CONSIDER OTHER ACQUISITION PROPOSALS

     C-Cube has agreed that, except in the circumstances described below, it
will not, directly or indirectly:

     - solicit, initiate or encourage any Acquisition Proposal (as defined
       below);

     - engage in discussions or negotiations with, or disclose any non-public
       information relating to C-Cube or its subsidiaries or afford access to
       the properties, books or records of C-Cube or its subsidiaries to, any
       person (other than LSI Logic or any designees of LSI Logic) concerning or
       in connection with an Acquisition Proposal;

     - withhold, withdraw, modify, change in a manner adverse to LSI Logic or
       fail to make a recommendation that C-Cube stockholders accept the
       exchange offer and approve and adopt the merger agreement;

     - approve, endorse or recommend an Acquisition Proposal;

     - release or permit the release of any person from, or waive or permit the
       waiver of any provision of, any confidentiality, "standstill" or similar
       agreement (other than as required pursuant to the terms of the relevant
       agreement) under which C-Cube or any of its subsidiaries has any rights;
       or

     - fail to use commercially reasonable efforts to enforce or cause to be
       enforced any "standstill" agreement if LSI Logic should request that
       C-Cube do so.

                                        57
   63

     However, if:

     - C-Cube receives an unsolicited bona fide written Acquisition Proposal
       that is not withdrawn;

     - C-Cube provides LSI Logic with prior notice of any meeting of C-Cube's
       board of directors, at the same time the notice is given to C-Cube's
       directors, at which C-Cube's board of directors will consider and
       determine whether the Acquisition Proposal is, or could reasonably be
       expected to be, a Superior Proposal (as defined below);

     - C-Cube's board of directors believes in good faith, after consultation
       with C-Cube's financial advisor, that the Acquisition Proposal is, or
       could reasonably be expected to be, a Superior Proposal;

     - C-Cube's board of directors believes in good faith, after consultation
       with C-Cube's outside legal counsel, that the failure to engage in
       negotiations or discussions, provide information, withhold, withdraw,
       modify, change or fail to make a recommendation that C-Cube stockholders
       accept the exchange offer and approve and adopt the merger agreement,
       approve, endorse or recommend the Acquisition Proposal or release or fail
       to enforce the "standstill" or similar agreement is inconsistent with the
       fiduciary duties of C-Cube's board of directors under applicable law;

     - at or prior to furnishing any nonpublic information to, entering into
       discussions or negotiations with, or releasing from a "standstill" or
       similar agreement, or failing to enforce a provision of a "standstill" or
       similar agreement against, any person, C-Cube gives LSI Logic written
       notice of the identity of such person and of C-Cube's intention to
       furnish nonpublic information to, enter into discussions or negotiations
       with, or release from a "standstill" or similar agreement or fail to
       enforce a provision against, such person, and C-Cube receives from such
       person an executed confidentiality agreement not substantially less
       favorable to C-Cube than the confidentiality agreement between LSI Logic
       and C-Cube, dated as of March 16, 2001; and

     - at or prior to furnishing any nonpublic information to such person,
       C-Cube furnishes the nonpublic information to LSI Logic (to the extent
       the nonpublic information has not been previously furnished by C-Cube to
       LSI Logic),

     then C-Cube may:

     - furnish information with respect to C-Cube and its subsidiaries to such
       person;

     - participate in negotiations with such person regarding the Acquisition
       Proposal;

     - enter into discussions or negotiations with, or release from a
       "standstill" or similar agreement or fail to enforce such a provision
       against, such person;

     - withhold, withdraw, modify or change in a manner adverse to LSI Logic its
       recommendation that C-Cube stockholders accept the exchange offer and
       approve and adopt the merger agreement; or

     - approve, endorse or recommend the Acquisition Proposal.

     Under the terms of the merger agreement, C-Cube agreed to immediately cease
and cause to be terminated any existing discussions with any person that related
to any Acquisition Proposal.

     C-Cube must promptly, and in any event within one business day, after
receipt of any Acquisition Proposal provide LSI Logic with a copy of any written
Acquisition Proposal and the name of the person making the Acquisition Proposal
and a written statement with respect to any non-written Acquisition Proposal
received, which statement is required to include the identity of the person
making the Acquisition Proposal and the terms of the Acquisition Proposal.
C-Cube must promptly, and in any event within one business day, advise LSI Logic
of any material modification or proposed modification to the Acquisition
Proposal.

                                        58
   64

     An "Acquisition Proposal" means:

     - any offer or proposal for a merger, consolidation, recapitalization,
       liquidation or other business combination involving C-Cube or the
       acquisition or purchase of 15% or more of any class of equity securities
       of C-Cube;

     - any tender offer (including self-tenders) or exchange offer that if
       completed would result in any person beneficially owning 15% or more of
       any class of any equity securities of C-Cube; or

     - any transaction involving the sale, lease, license or other disposition,
       by sale, merger or otherwise, of 15% or more of the book or market value
       of assets (including securities of any subsidiary of C-Cube) of C-Cube
       and its subsidiaries, taken as a whole.

     A "Superior Proposal" means an unsolicited, bona fide written proposal made
by a third party involving the purchase by the third party of a majority of the
outstanding shares of C-Cube common stock or 50% or more of the book or market
value of the assets (including securities of any subsidiary of C-Cube) of C-Cube
and its subsidiaries taken as a whole, which C-Cube's board of directors
believes in good faith, after consultation with C-Cube's financial advisor, (i)
is reasonably likely to result in a transaction providing greater benefits to
C-Cube stockholders than those provided pursuant to the merger agreement, and
(ii) if applicable, is reasonably capable of being financed by the person making
the Acquisition Proposal.

     The terms of the merger agreement do not prohibit C-Cube or C-Cube's board
of directors from taking and disclosing to C-Cube stockholders a position with
respect to a tender offer or an exchange offer by a third party, or from making
any disclosure required by applicable law. However, in connection with any
Acquisition Proposal, C-Cube's board of directors may not withhold, withdraw,
modify or change in a manner adverse to LSI Logic, or fail to make, a
recommendation that C-Cube stockholders accept the exchange offer and approve
and adopt the merger agreement, and C-Cube's board of directors may not approve,
endorse or recommend any Acquisition Proposal, unless the conditions described
above under the caption "Limitation on C-Cube's Ability to Consider Other
Acquisition Proposals" are satisfied.

     C-Cube agreed to request each person that has executed, on or after January
1, 2000, a confidentiality agreement in connection with its consideration of any
Acquisition Proposal or any equity investment, to return all confidential
information that was furnished pursuant to the confidentiality agreement by or
on behalf of C-Cube or any of its subsidiaries.

EMPLOYEE BENEFITS

     The merger agreement contemplates that the employees of C-Cube and any of
its subsidiaries who become and remain employees of LSI Logic or any of its
subsidiaries after the completion of the merger will be treated as favorably as
other similarly situated employees of LSI Logic or any of its subsidiaries with
respect to compensation, employee benefits and terms and conditions of
employment.

     The merger agreement also contemplates that, for a period of one year
following the completion of the merger, LSI Logic will, at its election, either:

     - continue, or cause its subsidiaries to continue, any C-Cube employee
       benefit plans that were in effect as of March 26, 2001; or

     - arrange for each participant in any C-Cube employee benefit plan who
       becomes an employee of LSI Logic or any of its subsidiaries to be
       eligible to participate in any similar LSI Logic employee benefit plans
       or programs, on terms that are no less favorable to the employee than
       those offered to similarly situated employees of LSI Logic.

     In addition, the merger agreement contemplates that, no later than one year
after the completion of the merger, all former employees of C-Cube or any of its
subsidiaries who continue to be employed by LSI Logic or any of its subsidiaries
will be eligible to participate in all employee benefit plans of LSI Logic on
terms no less favorable than those offered to similarly situated employees of
LSI Logic.

                                        59
   65

     LSI Logic has agreed that (with certain exceptions), to the extent service
is relevant for purposes of eligibility, participation or vesting under any
employee benefit plan, program or arrangement established or maintained by LSI
Logic or its subsidiaries for the benefit of employees of C-Cube or its
subsidiaries, or for benefit accrual (other than under any defined benefits
pension plan and other than where it would result in a duplication of benefits),
and to the extent permitted by law, the employees of C-Cube and its subsidiaries
will be credited for service accrued with C-Cube or its subsidiaries prior to
the completion of the merger. In addition, with respect to any welfare benefit
plans to which these C-Cube employees may become eligible, LSI Logic has agreed
to cause the welfare benefit plans to provide credit for the year in which the
merger is completed for documented co-payments, deductibles and maximum
out-of-pocket payments made by these C-Cube employees and has agreed, to the
extent permitted by law, to waive all pre-existing condition exclusions and
waiting periods, other than limitations or waiting periods that had not been
satisfied, under any welfare plans maintained by C-Cube and its subsidiaries
prior to the completion of the merger.

CONDITIONS TO THE EXCHANGE OFFER

     The obligation of LSI Logic to accept for exchange, and to deliver shares
of LSI Logic common stock in exchange for, shares of C-Cube common stock that
are validly tendered and not properly withdrawn, is subject to the satisfaction
or, where permissible, the waiver of the conditions described in the merger
agreement, including the following conditions:

     THE MINIMUM TENDER CONDITION

     Prior to the expiration date of the exchange offer, as it may be extended
pursuant to the merger agreement, there must be validly tendered, in accordance
with the terms of the exchange offer, and not withdrawn a number of shares of
C-Cube common stock that, when added to any shares of C-Cube common stock owned
by LSI Logic, is equal to at least a majority of the sum of:

     - the total number of shares of C-Cube common stock outstanding immediately
       prior to the expiration date of the exchange offer, as it may be extended
       pursuant to the merger agreement; and

     - a number of shares of C-Cube common stock, determined by LSI Logic, up to
       the total number of shares of C-Cube common stock issuable upon the
       exercise or conversion of all options, warrants, rights and convertible
       securities, if any, that will be vested by September 30, 2001.

     OTHER CONDITIONS TO THE EXCHANGE OFFER

     The exchange offer is also subject to the conditions that, prior to the
expiration of the exchange offer, as it may be extended pursuant to the merger
agreement:

     - The waiting periods under the HSR Act and under other applicable
       antitrust laws must have expired or been terminated and any applicable
       consents or clearances under foreign antitrust laws must have been
       obtained;

     - The registration statement on Form S-4 relating to this transaction must
       have been declared effective under the Securities Act of 1933, and must

     - The shares of LSI Logic common stock that are to be issued in the
       transaction must have been approved for listing on The New York Stock
       Exchange, subject to official notice of issuance, or must be exempt from
       the listing requirements under then applicable laws, regulations or rules
       of The New York Stock Exchange;

     - LSI Logic and C-Cube must have received opinions from their respective
       counsel, in form and substance reasonably satisfactory to both, to the
       effect that the transaction will be a tax-free reorganization for federal
       income tax purposes, and the respective opinions must not have been
       subsequently rescinded;

                                        60
   66

     - (i) There must not have been any action taken, or any statute, law,
       ordinance, rule, regulation, injunction, judgment, order or decree
       proposed, entered, enacted, enforced, promulgated, issued or deemed
       applicable to the exchange offer or the merger by any governmental
       entity, other than the application of the waiting period provisions of
       the HSR Act to the transaction, that seeks to do any of the things
       described in any of paragraphs (1) through (7) below, (ii) there must not
       be pending or threatened any action, suit or proceeding by any
       governmental entity against LSI Logic, C-Cube or any of their respective
       subsidiaries that seeks to do any of the things described in any of
       paragraphs (1) through (7) below, and (iii) there must not be pending any
       action, suit or proceeding by any other person (if that person is a party
       to a C-Cube contract that was not provided or made available to LSI Logic
       on or prior to March 26, 2001), against LSI Logic or C-Cube or any of
       their respective subsidiaries (if the action, suit or proceeding is based
       on that person's rights under the relevant C-Cube contract), that is
       substantially likely to do any of the things described in any of
       paragraphs (1) through (7) below:

      (1) prohibit, or make illegal, the acceptance for exchange or the exchange
          of shares of C-Cube common stock or the completion of the exchange
          offer or the merger;

      (2) render LSI Logic unable to accept for exchange or exchange some or all
          of the shares of C-Cube common stock;

      (3) impose material limitations on the ability of LSI Logic or Clover

          the shares of C-Cube common stock, including the right to vote the
          shares of C-Cube common stock purchased by it on all matters properly
          presented to C-Cube stockholders;

      (4) prohibit or impose any material limitations on LSI Logic's direct or
          indirect ownership or operation (or that of any of its affiliates) of
          all or a material portion of their or C-Cube's businesses or assets;

      (5) compel LSI Logic or its affiliates to dispose of or hold separate any
          portion of the business or assets of C-Cube or LSI Logic and their
          respective subsidiaries which would be material in the context of
          C-Cube and its subsidiaries taken as a whole or LSI Logic and its
          subsidiaries taken as a whole;

      (6) oblige C-Cube, LSI Logic or any of their respective subsidiaries to
          pay material damages or otherwise become subject to materially adverse
          consequences in connection with any of the transactions contemplated
          by the merger agreement; or

      (7) otherwise result in a material adverse effect on C-Cube or, as a
          result of the transactions contemplated by the merger agreement, a
          material adverse effect on LSI Logic;

     - C-Cube must have not have materially breached any of its covenants,
       obligations or agreements under the merger agreement;

     - The representations and warranties of C-Cube contained in the merger
       agreement must have been true as of March 26, 2001 and must be true on
       and as of the date of the expiration of the exchange offer, as it may be
       extended pursuant to the merger agreement, with the same force and effect
       as if made as of such date, except:

      - in each case or in the aggregate, as does not constitute, and is not
        reasonably expected to result in, a material adverse effect on C-Cube;

      - for changes contemplated by the merger agreement; and

      - for those representations and warranties which address matters only as
        of a particular date, which representations must have been true (subject
        to the material adverse effect qualifications and limitations described
        above) as of such particular date;

                                        61
   67

     - The representations and warranties made by C-Cube regarding its
       capitalization must have been true in all material respects as of March
       26, 2001;

     - Except as disclosed to LSI Logic by C-Cube, since December 31, 2000,
       there must not have been any material adverse effect on C-Cube or the
       occurrence of any event or circumstance that would reasonably be expected
       to have a material adverse effect on C-Cube; and

     - The merger agreement must not have been terminated in accordance with its
       terms.

If any one of the above conditions is not met, and, in the good faith judgment
of LSI Logic, it is inadvisable to proceed with the exchange offer or the
acceptance for exchange of, or the delivery of shares of LSI Logic common stock
in exchange for, shares of C-Cube common stock, then LSI Logic will not be
required to accept for exchange, or deliver any shares of LSI Logic common stock
in exchange for, any shares of C-Cube common stock tendered.

     LSI Logic reserves the absolute right, in its sole discretion, subject to
terms of the merger agreement, to waive, in whole or in part, any of the
conditions to the exchange offer. However, the minimum tender condition, the
United States antitrust clearance condition, the conditions relating to the
effectiveness of the registration statement for the shares of LSI Logic common
stock to be issued in the exchange offer and the listing of shares of LSI Logic
common stock on The New York Stock Exchange and the condition that C-Cube must
have received a tax opinion from its legal counsel, as described above, may not
be waived by LSI Logic without C-Cube's consent.

     As used in the merger agreement, "material adverse effect" as it relates to
LSI Logic or C-Cube means a material adverse effect on or change in the
financial condition, business, assets or results of operations of LSI Logic or
C-Cube and their respective subsidiaries, each taken as a whole, as the case may
be. However, in no event shall any effect that directly results from:

     - any change in general economic conditions that does not affect such party
       and its subsidiaries, taken as a whole, in a substantially
       disproportionate manner;

     - any adverse change affecting the semiconductor industry generally that
       does not affect such party and its subsidiaries, taken as a whole, in a
       substantially disproportionate manner;

     - any failure by such party to meet revenue and earnings estimates in and
       of itself; and

     - the announcement or pendency of the merger agreement,

constitute, or be considered in determining the existence of, a material adverse
effect on a party.

CONDITIONS TO THE MERGER

     The obligations of LSI Logic and C-Cube to complete the merger are subject
to the satisfaction or waiver of the following conditions:

     - if required by Delaware law, the merger agreement must have been adopted
       and the merger approved;

     - LSI Logic must have accepted for exchange, and delivered shares of LSI
       Logic common stock in exchange for, all shares of C-Cube common stock
       that are validly tendered and not properly withdrawn, pursuant to the
       exchange offer;

     - no provision of any applicable law or regulation and no judgment,
       injunction, order or decree prohibits the completion of the merger or the
       other transactions contemplated by the merger agreement; and

     - the registration statement on Form S-4 relating to the transaction,
       including any post-effective amendment, must have become effective, and
       must not be the subject of any stop order or proceedings seeking a stop
       order, and any material "blue sky" and other state securities laws
       applicable to the registration and qualification of shares of C-Cube's
       common stock must have been complied with.
                                        62
   68

TERMINATION OF THE MERGER AGREEMENT

     TERMINATION BY MUTUAL AGREEMENT

     LSI Logic and C-Cube may terminate the merger agreement at any time prior
to the completion of the merger by mutual written consent.

     TERMINATION BY EITHER LSI LOGIC OR C-CUBE

     Either LSI Logic or C-Cube may terminate the merger agreement at any time
prior to the completion of the merger if:

     - the exchange offer expires or terminates in accordance with the terms of
       the merger agreement without LSI Logic having accepted for exchange any
       shares of C-Cube common stock, except that the right to terminate the
       merger agreement for the reason identified in this paragraph is not
       available to any party whose action or failure to act has been a
       principal cause of the expiration or termination of the exchange offer
       without shares of C-Cube common stock having been accepted for exchange,
       if the action or failure to act constitutes a breach of the merger
       agreement;

     - the exchange offer has not been completed on or before September 30,
       2001, except that the right to terminate the merger agreement for the
       reason identified in this paragraph is not available to any party whose
       action or failure to act has been a principal cause of the failure of the
       exchange offer to have been completed on or before such date if the
       action or failure to act constitutes a breach of the merger agreement; or

     - there is any applicable law or regulation that makes completion of the
       exchange offer or the merger illegal or otherwise prohibited, or any
       final and nonappealable judgment, injunction or order that prohibits the
       completion of the exchange offer or the merger.

     TERMINATION BY LSI LOGIC

     LSI Logic may terminate the merger agreement at any time prior to the
acceptance for exchange of shares of C-Cube common stock pursuant to the
exchange offer, if any of the following (a "Triggering Event") occurs:

     - C-Cube's board of directors withdraws, modifies or amends in any respect
       adverse to LSI Logic its recommendation that C-Cube stockholders accept
       the exchange offer or its recommendation that C-Cube stockholders approve
       the merger agreement;

     - C-Cube's board of directors makes any disclosure to C-Cube stockholders
       or a public announcement that makes it reasonably apparent that, absent
       the restrictions described in the merger agreement, C-Cube's board of
       directors would withdraw, modify or amend in any respect adverse to LSI
       Logic its recommendation that C-Cube stockholders accept the exchange
       offer or its recommendation that C-Cube stockholders approve the merger
       agreement;

     - C-Cube's board of directors recommends, or resolves or announces an
       intention to recommend, any Acquisition Proposal to C-Cube stockholders;

     - any tender offer or exchange offer (other than the exchange offer being
       made by LSI Logic as described in this prospectus) for 15% or more of the
       outstanding shares of C-Cube common stock is announced or commenced and
       either C-Cube's board of directors recommends acceptance of the tender
       offer or exchange offer, or within 10 business days of the commencement
       of the tender offer or exchange offer, C-Cube's board of directors fails
       to recommend against approval of the tender offer or exchange offer by
       C-Cube stockholders; or

     - there is a material breach of C-Cube's obligations described in the
       section entitled "-- Limitation on C-Cube's Ability to Consider Other
       Acquisition Proposals" above, and within 10 days of LSI Logic becoming
       aware of the material breach, LSI Logic gives C-Cube a written
       termination notice.

                                        63
   69

     In addition, LSI Logic may terminate the merger agreement, at any time
prior to the acceptance for exchange of shares of C-Cube common stock pursuant
to the exchange offer, if:

     - C-Cube materially breaches any covenant or agreement in the merger
       agreement; or

     - any representation or warranty of C-Cube was untrue when made or becomes
       untrue such that, pursuant to the terms of the merger agreement, LSI
       Logic would not be required to accept for exchange any shares of C-Cube
       common stock tendered pursuant to the exchange offer if the expiration of
       the exchange offer had occurred on the date the untruth of the
       representation or warranty is communicated in writing to C-Cube by LSI
       Logic.

If, however, the breach of the covenant or agreement by C-Cube, or the untruth
of the representation or warranty of C-Cube, is curable by C-Cube through the
exercise of commercially reasonable efforts, then LSI Logic may not terminate
the merger agreement until the earlier of 30 days after delivery of written
notice from LSI Logic to C-Cube of the breach or untruth, or the date on which
C-Cube ceases to use commercially reasonable efforts to cure the breach or
untruth.

     TERMINATION BY C-CUBE

     C-Cube may terminate the merger agreement at any time prior to the
acceptance for exchange of shares of C-Cube common stock pursuant to the
exchange offer (but not less than five business days after LSI Logic's receipt
of the written notice referred to below), to enter into a definitive acquisition
agreement with respect to a Superior Proposal, as long as:

     - C-Cube is not in breach of its obligations, summarized above in the
       section entitled "-- Limitation on C-Cube's Ability to Consider Other
       Acquisition Proposals," in connection with such Superior Proposal;

     - C-Cube has notified LSI Logic in writing that C-Cube has received a
       Superior Proposal and intends to enter into a definitive acquisition
       agreement with respect to the Superior Proposal and has attached a copy
       of the most current version of the definitive acquisition agreement to
       the notice; and

     - LSI Logic does not, within five business days of receiving the notice
       described above, make an offer that C-Cube's board of directors
       determines in good faith, after consultation with its financial advisor
       and its outside legal counsel, provides greater benefits to C-Cube
       stockholders than the Superior Proposal.

     In addition, C-Cube may terminate the merger agreement, at any time prior
to the acceptance for exchange of shares of C-Cube common stock pursuant to the
exchange offer, if:

     - LSI Logic materially breaches any covenant or agreement in the merger
       agreement; or

     - any representation or warranty of LSI Logic was untrue when made or
       becomes untrue such that, in the aggregate, the untruths would reasonably
       be expected to have a material adverse effect on LSI Logic.

If, however, the breach of the covenant or agreement by LSI Logic, or the
untruth of the representation or warranty of LSI Logic, is curable by LSI Logic
through the exercise of commercially reasonable efforts, then C-Cube may not
terminate the merger agreement until the earlier of 30 days after delivery of
written notice from C-Cube to LSI Logic of the breach or untruth, or the date on
which LSI Logic ceases to exercise commercially reasonable efforts to cure the
breach or untruth.

     If the merger agreement is terminated pursuant to any of the provisions
described above in this section, the merger agreement will become void and of no
effect, with no liability on the part of LSI Logic or C-Cube, other than
liability for a willful breach of the merger agreement or the payment by C-Cube
of the termination fee described below. However, if the merger agreement is so
terminated, any information and documents received by LSI Logic or C-Cube, or
their respective representatives, from any other party to the merger agreement,
whether furnished before or after the date of the merger agreement, is required
                                        64
   70

to be held in accordance with the "Confidentiality Agreement," dated as of March
16, 2001, between LSI Logic and C-Cube. In addition, if the merger agreement is
so terminated, the "standstill" provisions contained in the Confidentiality
Agreement (which were terminated upon the signing of the merger agreement) will
again become operative in accordance with their terms, unless the merger
agreement is terminated:

     - by LSI Logic because a Triggering Event has occurred;

     - by C-Cube to enter into a definitive acquisition agreement with respect
       to a Superior Proposal (as described more fully above);

     - by LSI Logic because of the breach or untruth of a covenant, agreement
       representation or warranty of C-Cube (as described more fully above); or

     - under certain circumstances pursuant to which the termination fee
       described below may become payable.

TERMINATION FEE; EXPENSES

     C-Cube has agreed to pay to LSI Logic a termination fee in an amount equal
to $33 million, if the merger agreement is terminated before shares of C-Cube
common stock are accepted for exchange pursuant to the exchange offer and any of
the following additional circumstances exist:

     - The merger agreement is terminated by LSI Logic because a Triggering
       Event has occurred; or

     - The merger agreement is terminated by either LSI Logic or C-Cube because
       the exchange offer expires or terminates in accordance with the terms of
       the merger agreement without LSI Logic having accepted for exchange any
       shares of C-Cube common stock or the exchange offer has not been
       completed on or before September 30, 2001, if:

      - prior to the termination of the merger agreement, an Acquisition
        Proposal is publicly announced and is not publicly and unconditionally
        withdrawn (taking into account that the percentages in the definition of
        "Acquisition Proposal" are changed from 15% to 40% for the purpose of
        this clause and the following clause); and

      - within 12 months following the termination of the merger agreement,
        either a transaction contemplated by any Acquisition Proposal is
        completed or C-Cube enters into a definitive agreement with respect to
        any Acquisition Proposal and the transaction contemplated by that
        definitive agreement is later completed; or

     - The merger agreement is terminated by C-Cube to enter into a definitive
       acquisition agreement with respect to a Superior Proposal.

     The merger agreement provides that all expenses, other than any termination
fee, incurred in connection with the merger agreement and the transactions
contemplated by the merger agreement are to be paid by the party incurring such
expenses. However, LSI Logic and C-Cube are required to share equally all fees

                         INFORMATION RELATING TO C-CUBE

MAY 2000 RESTRUCTURING

     "C-Cube Microsystems Inc." was incorporated as a California corporation in
1988 and reincorporated in Delaware in 1994. In 1996, C-Cube Microsystems Inc.
acquired all of the capital stock of DiviCom Inc. After operating for three
years as a combined entity, in 2000, C-Cube Microsystems Inc.'s semiconductor
business was spun off as C-Cube Semiconductor Inc. to the stockholders of C-Cube
Microsystems Inc. C-Cube Microsystems Inc. then merged with Harmonic Inc. in May
2000. Immediately after the merger, the semiconductor business changed its name
back to C-Cube Microsystems Inc. This new entity (including its direct and
indirect subsidiaries) is referred to as C-Cube in this prospectus.

GENERAL

     C-Cube designs, develops, has manufactured and sells semiconductors,
software and systems for digital audio and video applications. As a major
supplier of such products, C-Cube has played a role in enabling the growth of
digital audio and video. C-Cube is focused on working with its original
equipment manufacturer, or OEM, customers and service providers to enable key
applications in its consumer and communications target markets. In the consumer
market, C-Cube is focused on playback and recordable digital video disc and
video compact disc as well as digital video recorders and digital VHS recorders.
The communications market targets interactive set-top boxes, cable front ends,
cable modems and broadcast encoders, and other emerging applications. Users of
these products will be able to record hours of digital video disc-quality video
obtained from any video source, whether television, video cassette recorder,
digital video camcorder or analog camcorder. Once users have recorded the video,
they will be able to edit and play back the video on standard personal computers
and store the resulting video to digital video disc, web pages, e-mail,
recordable compact disc or personal computer hard-disk drives.

     COMPRESSION ENABLES MASS-MARKET APPLICATIONS OF DIGITAL VIDEO

     Representing video in uncompressed digital form requires a large amount of
data, which in the past has made storage or transmission economically
impractical. To store a single uncompressed digital video movie requires up to
25 discs, whereas a compressed digital video movie can be stored onto one disc.
The sheer size of uncompressed digital video has relegated it to niche
applications of small volumes.

     The very nature of video information lends itself to compression. Any video
sequence has inherent redundancies. For example, one frame of a movie often
differs very little from the next successive frame. Through digital compression
techniques, the redundancies in video data can be detected and eliminated,
significantly reducing the overall amount of data needed to recreate the
original image without affecting the image quality. Using video compression
techniques, a single satellite transponder can broadcast 8 to 12 programs
instead of the partial program possible with uncompressed video. C-Cube believes
that the design and deployment of cost-effective and practical video compression
technology is critical to the development of mass-market applications.

     STANDARDS ENHANCE THE GROWTH OF DIGITAL VIDEO MARKETS

     As digital video markets develop, so does the need for standards to ensure
that products from different manufacturers use the same formats for video
information. Throughout C-Cube's history, it has been an active participant and
respected technology pioneer on International Organization for Standardization
committees charged with creating standards for still image and digital video
compression.

     Key standards that have driven the growth of digital video include the
joint photographic experts group, or JPEG, standard for still-image compression
and two moving pictures experts group standards for digital video and audio
compression. The MPEG-1 standard enabled the first digital video consumer
products such as the first video compact disc, while the more recent MPEG-2
standard has become the accepted compression format in diverse applications such
as digital satellite, cable and terrestrial television

                                        69
   75

as well as professional video editing, digital VHS and digital video disc. The
adoption and acceptance of these standards has contributed greatly to the growth
of digital video markets during the 1990s.

     MATHEMATICAL RULES GOVERN COMPRESSION WHICH DETERMINES VIDEO QUALITY

     As vital as the International Organization for Standardization standards
have been to the development of digital video, they have a built-in limitation.
The standards determine interoperability, not video quality. More specifically,
the standards define the format for compressed video data. A MPEG-compliant
encoder, which is the compression device, will create data that a MPEG-compliant
decoder, which is the decompression device, can reconstruct into a video image.
However, the process of encoding necessarily involves discarding some of the
image information to achieve compression. If the encoder is smart, that is, if
it can correctly determine which information is redundant or insignificant to
the video quality, then the encoded video will be a faithful representation of
the original video and the decoder can create a high-quality video image.
Nevertheless, if the encoder makes poor choices and discards important video
information, then the decoder cannot compensate. The reconstructed image will be
poor in comparison to the original image. Encoder design, therefore, is a
critically important determining factor for video quality.

     At the heart of encoder design is the development of encoding algorithms,
the mathematical rules that govern how the large volume of uncompressed video is
reduced to a manageable size without adversely affecting image quality. One of
C-Cube's core strengths has been its expertise in the development, testing and
refinement of these mathematical rules. These mathematical formulas are
proprietary and represent C-Cube's vital intellectual property. By incorporating
these highly efficient and powerful algorithms into its products, C-Cube has
consistently been recognized as the industry leader in digital video encoding.
As evidence of this leadership, its products perform the encoding for the
majority of digital video television currently being broadcast. Also, C-Cube is
one of a select group of technology companies that have been recognized by The
National Academy of Television Arts and Sciences for technical achievement, as
shown by their award of a special technology Emmy(TM) to C-Cube Semiconductor
Inc. in 1995.

     C-Cube differentiates its products from competitors by offering both
encoding and decoding products that are not only fully compliant with the MPEG-1
or -2 international standards (and therefore interoperable with equipment from
many other suppliers), but at the same time provide superior image quality
(enhancing the viewing experience), are feature rich and are highly integrated
and therefore cost competitive. All of C-Cube's products are programmable,
permitting the incorporation of sophisticated system-level features after the
chip design is completed, while lessening design time, risk and system cost.
C-Cube also develops proprietary product extensions and features such as
RealSonic(TM) home theater sound enhancement and ClearView(TM) error correction
technology.

     MARKET TRENDS

     C-Cube addresses two broad industries where digital audio and video is
used:

     - consumer electronics; and

     - communications.

This section describes some of the trends affecting these markets.

     Consumer Electronics. Through the use of MPEG compression, video can be
stored, reproduced and distributed on the same media currently in use for other
types of digital data, such as 5-inch, or 12 cm, compact discs that are commonly
used for digital audio. Emerging applications for digital video capture,
playback and distribution at the consumer level are being advanced by the rapid
adoption of new consumer-oriented media formats such as digital video disc
players, video compact disc players, digital VHS recordable digital video discs,
as well as consumer digital video cameras and camcorders.

     Recordable Digital Video Disc and Digital VHS. In 1999, several original
equipment manufacturers demonstrated consumer-oriented products positioned as
video cassette recorder replacements. C-Cube

                                        70
   76

believes that rapid growth in this market will occur only when single-chip
codecs, which are an encoder/decoder combination, reach a price point low enough
to enable a recordable unit at prices that will support a mass market. Once this
milestone is achieved, however, the potential for wide consumer acceptance of
digital video cassette recorder replacements is expected to be high. Key
advantages of disc-based recording include:

     - higher video quality of digital versus analog recording;

     - the convenience of discs over tape; and

     - the ability to integrate the video cassette recorder recording function
       with other desirable consumer features such as easy program recording,
       time-shifting of programs and digital video disc playback.

     Key advantages of digital-VHS include:

     - the ability to record up to 24 hours of video on a single tape;

     - capability to record high-definition television; and

     - compatibility with VHS and Super-VHS, thus preserving existing consumer
       video libraries stored in VHS format.

     Digital Video Disc Player, or DVD. The DVD standard was defined
specifically for the very high-quality playback of feature-length movies. The
DVD format, now commercially available, provides up to 135 minutes of playing
time (270 for double-sided) on a disc the same physical size as an audio compact
disc with four times the image resolution of a standard video compact disc.
Digital video disc uses MPEG-2 compression technology.

     Video Compact Disc Player, or VCD. A VCD is essentially an audio compact
disc player with a MPEG-1 decoder and a video output. While adding this
functionality marginally increases the cost to manufacture a typical compact
disc player, these machines now have the ability to play movies, music videos
and other titles from MPEG-1 encoded compact discs. The physical video compact
disc format is identical to a standard audio compact disc and is limited to 72
minutes playing time with video quality that is generally perceived as
comparable to an analog VHS tape. Several thousand video compact disc titles are
now available, including movies, music videos and karaoke titles. The VCD format
has thus far received mass-market adoption in China. In 1998, leading Chinese
manufacturers and the Chinese government introduced an enhanced version of video
compact disc known as Chaoji video compact disc, also referred to as super-VCD,
or S-VCD. This enhanced version features MPEG-2 video quality that is comparable
to DVD video and is backward compatible with VCD titles.

     C-Cube anticipates that the VCD and S-VCD markets will eventually
transition to DVD.

     Non-Linear Editing Systems. The capabilities of non-linear editing systems
continue to grow. Sophisticated features such as the ability to allow a user to
edit video and re-sequence it, which was once the province of professional
studios, are now coming to the consumer and prosumer markets. An important
enabling factor is the availability of low-cost recordable compact disc drives,
which provide a convenient and cost-effective means to store edited digital
video. C-Cube expects this trend to accelerate in 2000, as the higher capacity
recordable digital video disc drives become more common in personal computers.

     Communications. The ability to compress digital video into a more compact
form, which provides significant storage and transmission efficiencies, is
currently enabling a number of applications and capabilities in the
communications market in diverse segments such as satellite, cable, telephone
and wireless networks.

     Satellite. The first full-scale digital video transmission systems to
achieve full deployment were a series of direct broadcast satellite networks. By
combining the ability to compress digital video into a more compact form with
high-power Ku-band satellites, direct broadcast satellite systems typically
provide 100 or more channels to a large geographical area (e.g. the continental
United States). This expanded service

                                        71
   77

usually imposes a relatively low cost per subscriber since the only incremental
investment needed by subscribers is the purchase of a small dish and a decoder
box.

     To compete with other high-speed media, satellite service providers are
beginning direct broadcast satellite deployments using high-speed satellite data
transmission to the home. A disadvantage of this approach is that the return
channel uses a standard modem over telephone lines, thus limiting the
interactive nature of the service.

     A major trend in this market during 1998 and 1999 was consolidation through
a number of mergers and acquisitions, for example, the merger of DIRECTV and
USSB operations and the merger of AT&T and TCI operations. At the same time, the
satellite market saw the first trials of high-definition television
broadcasting.

     Cable. Cable providers are upgrading the level of their services using a
variety of network approaches. Open standards, such as those developed by
various standard-setting organizations, are expected to drive increased cable
revenue opportunities by creating a competitive marketplace for system network
equipment and end-terminal devices. New applications of DSL and hybrid fiber
cable, or HFC, are bringing more and more digital audio and video options to the
home.

     With the advantage of being able to support high-speed, two-way networks
combined with advanced interactive set-top boxes, the revenue base for cable
operators is expected to expand. This is a result of a growing client base and
increased revenue per client through a broad offering of interactive services
including web browsing and electronic commerce.

     Cable is also experiencing consolidation as smaller companies are unable to
make the transition to digital and also as telephony companies seek to get a
foothold in a competitive delivery mechanism into the home for both voice and
video.

PRODUCTS

     C-Cube supplies products for two main markets for digital video:

     - consumer electronics; and

     - communications.

     CONSUMER ELECTRONICS

     Recordable Digital Video. While DVD playback has achieved increasing
success in both consumer players and personal computer applications, C-Cube
believes that the high-volume applications of digital video in the consumer
world depend on the ability to both record and play back DVD-quality video.
Thus, C-Cube extended its DVxpert technology to the consumer world with the
DVxplore(TM) line of consumer codecs. DVxplore codecs are the world's first
single-chip consumer products to support both MPEG formats and the digital video
format used primarily in digital camcorders called DV. The initial focus was on
the personal computer market, where original equipment manufacturers use
DVxplore codecs to offer personal content creation, personal computer/television
and time-shifting applications. Users of these products are able to record hours
of DVD-quality video obtained from any video source, whether television, video
cassette recorder, digital video camcorder or analog camcorder. Once they record
the video, they are able to edit and play back the video on standard personal
computers and store the resulting video to optical disc, web pages, e-mail or
hard-disk drives.

     During 2000, C-Cube developed DVxcel(TM), the second-generation line of
consumer codecs. This product's focus is towards the recordable devices that
reside next to the television. DVxcel codecs are low-cost chips for the consumer
digital video market that will power a new generation of affordable, high-
quality digital video recording systems for the home. The chip builds takes on
the task of simultaneously recording and playing back, or encoding and decoding,
or broadcast quality video for optical-based recording and hard disk drive-based
Digital Video Recorder, or DVR, devices.

                                        72
   78

     Video cassette recorder replacement products began to appear on the market
in 1999, and are likely to continue to expand in the market over the next few
years. For consumer digital recorders, three types of media have emerged as
viable platforms for recording and playing back digital video: tape digital VHS;
optical recordable digital video disc; and hard disk digital video recorder.
C-Cube is developing products for all three emerging consumer digital recordable
platforms.

     Encoders for Editing Applications. Professional editing had been primarily
the province of motion-JPEG products due to the need for accurate cuts and
special effects. Because MPEG-compliant encoders essentially collapse some
frames to achieve high levels of compression, industry analysts doubted whether
MPEG could ever achieve the accuracy needed to supplant motion-JPEG products for
professional needs. However, C-Cube showed that MPEG is a viable format for
editing with the introduction of the DVxpress codecs. Based on the same
architecture as the DVxpert product, the DVxpress(TM) codecs feature C-Cube's
proprietary Frame-Accurate MPEG Editing, or FAME(TM), algorithm and dual-stream
decoding, two capabilities for professional editing.

     C-Cube's DVxpress-MX codec products can support both MPEG and DV formats,
to allow mixed-format editing where, for example, a MPEG stream and a DV stream
are edited together. This innovation is particularly important because DV is the
most popular format for consumer and professional digital camcorders, while MPEG
is the prevailing standard for transmission and storage. Panasonic, the
developer of the DV format, and Avid, a leading editing original equipment
manufacturers, both endorsed the DVxpress-MX codec as a significant step toward
unifying the moving pictures experts group and DV worlds. During 1999, many
leading providers of editing solutions introduced products based on DVxpress-
MX, including Matrox Electronic Systems, Pinnacle Systems, Accom and Fast
Multimedia.

     DVD Decoders. C-Cube's ZiVA(TM) family of DVD products includes decoders
and system-level design solutions for consumer original equipment manufacturers.
The ZiVA DVD decoder family incorporates several critical DVD functions into a
single chip. C-Cube addresses a critical concern of content owners with
SecureView(TM) copy protection and decryption technology. SecureView made ZiVA
decoders the first single-chip products to support the DVD consortium's copy
protection scheme.

     The newest generation of ZiVA-based products was announced in October 2000.
ZiVA-5 extended C-Cube's leadership in the DVD market with new features
including the industry's only full DVD-audio solution, an MP3 audio codec,
progressive-scan output, 2D-multiplane graphics engine, internet applications
and more. ZiVA-5 will enable customers to quickly bring a new variety of DVD
products to the market.

     Continuing the extension of the ZiVA technology, in January 2001 C-Cube's
DVD&MORE was introduced which enabled the market's first combination DVD player
and A/V recorder. Primarily targeted at the China market, C-Cube's DVD&MORE
combines DVD playback and supports VCD, S-VCD, MP3 and CD-audio playback.
C-Cube's DVD&MORE enables OEMs to quickly develop dual-deck optical disc players
that combine MPEG video and CD audio recording capability together with DVD
playback.

     Video Compact Disc Decoders. VCD is a consumer entertainment format based
on MPEG-1 technology. VCD players allow consumers to enjoy movies, documentaries
and karaoke played from a disc similar to an audio compact disc. C-Cube has been
a leading supplier of MPEG-1 decoders used in VCD players throughout the mid-and
late-1990s. C-Cube pioneered the MPEG-1 market with the introduction in 1992 of
the CL450 MPEG-1 video decoder, the first commercially available MPEG-1 video
decoder. The CL450 found uses in commercial and professional digital karaoke
players. It followed with the CL480 family of VCD decoders, products that
boosted C-Cube to market leadership in the rapidly growing market for VCD
players in China in the mid-1990s.

     C-Cube's current VCD product is the CL680 advanced VCD decoder. The CL680
decoder integrates an NTSC/PAL encoder, improved ClearView error concealment
technology and a new WideSound(TM) feature, which simulates a surround-sound
experience from two stereo channels. By fully utilizing the microcode
architecture of the CL680, C-Cube was able to integrate the system functions
directly on the CL680, effectively eliminating the need for the system
micro-controller.

                                        73
   79

     Chaoji Video Compact Disc Decoders, S-VCD. As the VCD market matured in
China, Chinese customers, original equipment manufacturers and government
agencies all saw a need for a higher quality video experience. Due to C-Cube's
expertise in both VCD and digital compact disc, C-Cube was well qualified to
help define the new standard. The result of this effort was the introduction of
the S-VCD standard, an extension to VCD that was endorsed by the Chinese
government and leading original equipment manufacturers.

     Soon after the adoption of the S-VCD standard, C-Cube introduced the CL8800
family of S-VCD decoders to C-Cube's partner original equipment manufacturers.
The CL8830 decoder is a full-featured product that features C-Cube's patented
RealSonic(TM) audio technology, offering significant advances in audio quality
for home theater and Karaoke applications. The CL8820 decoder targets more
price-sensitive products that do not demand the same audio quality as the CL8830
decoder. Both decoders are compatible with existing VCD and audio compact disc
formats. In 1999, C-Cube introduced the most integrated S-VCD decoder chip, the
CL8830A. Leading Chinese original equipment manufacturers have adopted the
CL8800 decoders for their S-VCD product offerings. In 2001, C-Cube believes that
the S-VCD market will continue to encroach on the VCD market as prices for S-VCD
systems decline.

     COMMUNICATIONS

     In most digital video applications, the encoding and decoding functions are
separated. For example, in broadcasting, the video is encoded by one or a small
number of encoders at the transmission facility, while a decoder at the viewer's
home reconstructs the broadcast for viewing. C-Cube has been, and continues to
be, a major supplier for both encoders and decoders for a full spectrum of
digital video applications. C-Cube has long recognized, however, that combining
the encoding and decoding functions into one processor, called a codec, creates
significant new market opportunities. C-Cube invested heavily in the development
of a single-chip MPEG-2 codec architecture and introduced DVxpert(TM), the first
product based on the new architecture, in August 1997. In 1999, C-Cube extended
the capabilities of the architecture with the introduction of C-Cube's
high-definition digital video product; the industry's first codec architecture
for high-definition television broadcasting and video production applications.

     Broadcast and Distribution Encoders. Encoders in the DVxpert family offer
improved image quality, efficient bandwidth utilization and reliability for
broadcasting and professional applications. The DVxpert broadcast encoders
target applications such as distribution, contribution, DVD authoring and video
servers. All DVxpert encoders use C-Cube's patented PerfectView(TM) feature,
which provides clear image quality with advanced video capabilities.

     One of the big issues broadcasters currently face is the migration to high
definition programming. The Federal Communications Commission has established a
target timeline for United States broadcasters to begin high-definition
television transmissions, but many infrastructure issues remain uncertain. In
1999, C-Cube introduced its high-definition digital video product to address
these issues. This product is a MPEG-2 encoder for high-definition television
broadcast applications, but also retains the capabilities of the standard
definition DVxpert products, enabling equipment manufacturers to deliver
flexible high definition/standard definition solutions and ease broadcasters'
transition issues.

     Interactive Set-top Box Decoders. The primary communications application
for MPEG-2 decoders is in the STB market. To reconstruct the compressed
broadcast program, several steps are required. First, the MPEG-2 stream must be
separated or demultiplexed into C-Cube's video and audio portions. Then the
video and audio must be decompressed. Finally, the video signal is combined with
other on-screen information, such as program guides, and displayed on a monitor.

     C-Cube has introduced several innovative products in this arena, starting
with the introduction of the CL9100 MPEG-2 video decoder in 1994. C-Cube
followed in 1995 by bringing to market the CL9110 Transport Demultiplexer which
was licensed from DiviCom, then a private company. Together, this two-chip
combination performed all the functions needed for digital video decoding and
was instrumental in enabling first-generation designs for digital set-top boxes.

                                        74
   80

     1996 saw the introduction of the AViA(TM) family of set-top box chips.
Building on the technology and market success of the CL9100 and CL9110 products,
the AViA platform offered high-performance graphics, better quality audio (Dolby
Digital(TM)), interoperability across both wired and wireless networks and a
tighter integration between the individual chips. In 1998, C-Cube introduced the
AviA@tv product, extending graphics capabilities and providing support for web
page and text display on TV screens. AviA@tv also provided Media Access Control,
or MAC, for two-way interactive networks.

     In September of 2000, C-Cube introduced the AViA-9600, an advanced system
on a chip for digital set-top boxes. This fourth generation set-top box solution
addresses key trends in the STB market such as digital time-shifting, consumer
product connectivity and innovative display of content. The AViA-9600 integrates
multiple dedicated processing using including host CPU, A/V decoder, audio DSP
and graphics processor. A new advanced graphics engine was designed in
collaboration with many leading service operators to support their needs for
advanced display of video and graphics. The integrated 150-MHz RISC CPU can act
as host and supports applications including digital time-shifting and soft
modem. The AViA-9600 integrates IEEE1394 "FireWire," USB and IDE interfaces to
support home networking and connection to digital cameras/camcorders, hard
drives and DTVs.

     Cable Front-End Communications Ics. In January of 1999, C-Cube acquired the
relevant communications activities of TV/ Com in order to reinforce this
successful strategic thrust into the arena of broadband communications network
products. One reason for the selection of TV/Com was that C-Cube's products have
been successfully deployed in the same networks and set-top boxes as its MPEG
solutions. Through this purchase, C-Cube gained access to key people,
intellectual property and designs including modulation and demodulation
technology. The combination of these capabilities with the relevant designs and
software from C-Cube's AViA product family and expertise in analog design, gives
C-Cube all the necessary components required to develop state-of-the-art, highly
integrated solutions for interactive digital television.

     In November of 2000, C-Cube introduced the MultiLynx family of integrated
cable front-end communications ICs, the first devices designed to support all
major world cable standards. The two MultiLynx ICs (CL2151 and CL2161),
developed for cable set-top boxes and cable modems, make it possible for
manufacturers to design a single product capable of being deployed on two-way
broadband cable networks anywhere in the world. During 2001, C-Cube will be
applying for DOCSIS certification with Cable Labs.

     The C-Cube MultiLynx CL2161 enables two-way communications using DOCSIS,
EuroDOCSIS and DVB in-band cable modem standards. It integrates a QAM, QAM/QPSK
modulator with a digital-to-analog converter for the return channel. An
integrated communications processor and dedicated MAC provides support for all
leading cable network standards. The communications processor also acts as the
host CPU and includes DSP extensions to support voice-over-IP, or VoIP, codec
algorithms simultaneously.

     The C-Cube MultiLynx CL2151 is the first cable modem chip designed
specifically for set-top boxes. In addition to the protocols supported by the
CL2161, the CL2151 supports DAVIC, DVS-178, Starvue and DVS-167 set-top MAC
protocols. It provides direct connection to a POD, or point of deployment,
module for OpenCable(TM) set-top designs. When combined with C-Cube's AviA-9600
set-top box decoder, the CL2151 enables the design of a cable set-top box with
two-way communications, VoIP, home networking and personal video recording with
a minimal bill of material costs.

     With this capability, C-Cube is now able to service the end-to-end
requirements of a digital video network including video compression in the head
end, network interfaces and the full spectrum of data, video, audio and graphics
requirements in the consumer terminal. This enables a new generation of
interactive services available through the television in the living room,
including web-based e-commerce, video e-mail and voice over the internet.

CONSUMER BRANDING PROGRAM

     C-Cube's consumer branding program, begun in 1996, saw a reduction in OEM
support in 2000. The rapid deployment of OEM's efforts to brand their own
products curbed the desire to follow C-Cube branding program guidelines. A
further obstacle to continuing the branding program arose from a slow down of
new products aimed at the Chinese market. This was done in an effort to balance
the geographic distribution of business worldwide. Name recognition of C-Cube
remains high in the China market and continues to be associated with high
quality, reliability and advanced technology.

CHANGING PRODUCT MIX: DEPENDENCE ON DECODER PRODUCTS

     C-Cube offers a number of products for a variety of applications. Since the
second quarter of 1995, sales of C-Cube's VCD decoder family of products have
represented a significant percentage of C-Cube's total net revenues. C-Cube
expects that revenues from its VCD decoder products including the CL680 and
Chaoji VCD families of products will decrease as a percentage of its total
revenues, but continue to account for a significant portion of its product
revenues in 2001. C-Cube expects that price competition will continue to result
in declining average selling prices for this family of products. C-Cube has
implemented several programs that have reduced costs associated with these
families of products. In the event that increases in unit sales and other
manufacturing efficiencies of these families of products do not offset
decreasing sales prices in the future, C-Cube's business and results of
operations would be materially and adversely affected. C-Cube anticipates that
overall gross margins may continue to decrease as a result of a number of
factors including anticipated declines in average selling prices over time. The
timing of volume shipments and the life cycles of C-Cube's products are
difficult to predict due in large measure to the emerging nature of the markets
for its products, the future effect of its product enhancements and its current
and future competitors. Declines in demand for C-Cube's products, particularly
the CL680 and Chaoji VCD families of products, whether as a result of
competition, technological change or otherwise, would have a moderately adverse
effect on C-Cube's business and results of operations.

     New Architecture. In January 2001, C-Cube DoMiNo was introduced as C-Cube's
newest architecture. C-Cube DoMiNo, which stands for Digital Media Network, was
unveiled as the world's first multi-stream, multi-format network media
processor, and integrates as many as 7 individual devices into a single chip.
The processing power is ten times that of a Pentium, yet uses only 5 percent of
the power, thus making it ideal for consumer electronic applications. It also
brings professional level digital audio and video capability down to consumer
price points. Although shipments for products containing this architecture will
not occur until 2002, C-Cube anticipates that new products will be announced
throughout 2001.

CUSTOMERS

     During 2000, Samsung and Pace each accounted for 11% of C-Cube's net
revenues. During 1999, no customer accounted for 10% or more of C-Cube's net
revenue. During 1998, Malata accounted for 10% of C-Cube's net revenues.

RESEARCH AND DEVELOPMENT

     C-Cube believes that the continued introduction of new products in its
target markets is essential to its growth. As of December 31, 2000, C-Cube had
257 full-time employees engaged in research and development. Expenditures for
research and development in 2000, 1999 and 1998 were approximately $72.2
million, $54.3 million and $52.8 million, respectively.

     C-Cube's operating results will depend to a significant extent on its
ability to continue to successfully introduce new products on a timely basis and
to reduce costs of existing products. In particular, C-Cube currently intends to
announce several new products over the next year, including next generation
MPEG-2

                                        76
   82

encoders and decoders and products based on C-Cube DoMiNo, the new architecture
announced in January 2001. The success of new product introductions is dependent
on several factors, including:

     - proper new product definition;

     - product cost;

     - timely completion and introduction of new product designs;

     - quality of new products;

     - differentiation of new products from those of C-Cube's competitors; and

     - market acceptance of C-Cube's and its customers' products.

     As a result, C-Cube believes that continued significant expenditures for
research and development will be required in the future. Because of the
complexity of its products, C-Cube has experienced delays from time-to-time in
completing development and introduction of new products, and as a result, has
from time-to-time not achieved the market share anticipated for such products.
C-Cube may not successfully identify new product opportunities and develop and
bring new products to market in a timely manner. Additionally, products or
technologies developed by others may render C-Cube's products or technologies
obsolete or noncompetitive, and its products may not be selected for design into
the products of its targeted customers.

SALES AND MARKETING

     C-Cube's sales and marketing strategy targets markets for which the
compression of digital video into a more compact form, providing significant
storage and transmission efficiencies, is an enabling technology in order to
achieve key design wins with industry leaders, as well as early adopters of
digital video technology. To implement its strategy, C-Cube has established a
direct sales and marketing force and a worldwide network of independent sales
representatives and distributors. In addition, C-Cube has a team of application
engineers who assist customers with designing in its products.

     In the United States, C-Cube sells its products through direct sales
channels, independent representatives and distributors. C-Cube records revenues
from product sales to customers at the time of shipment. Some of C-Cube's
agreements with its distributors permit limited stock rotation and provide for
price protection. Allowances for returns and adjustments, including price
protection, are provided at the time revenues from product sales are recorded.
Generally, C-Cube pays its independent sales representatives on a commission
basis. As of December 31, 2000, C-Cube has North American regional sales offices
in California and Quebec, and international sales offices in China, France,
Japan, Korea, Taiwan, and the United Kingdom. In Japan, C-Cube sells products
through the direct sales force of C-Cube Microsystems Japan, Inc. and two
distributors. C-Cube Microsystems Japan, Inc. was formed by C-Cube and Kubota
Corporation in 1988 and is currently owned 65% by C-Cube and 35% by Kubota. The
primary businesses of C-Cube Microsystems Japan, Inc. are the marketing, sales
and support of its products in Japan. Internationally, C-Cube has commissioned
sales representatives or distributors in Canada, Denmark, Finland, France,
Germany, Great Britain, Hong Kong, Ireland, India, Israel, Italy, Korea, Sweden
and Taiwan.

INTERNATIONAL BUSINESS ACTIVITIES

     During 2000, 1999 and 1998, international revenues accounted for
approximately 87%, 82% and 82% of C-Cube's net revenues, respectively. C-Cube
believes that international revenues will continue to account for a significant
portion of net revenues. C-Cube's success will depend in part upon its ability
to manage international marketing and sales operations. In addition, C-Cube
purchases a substantial portion of its manufacturing services from foreign
suppliers. C-Cube's international manufacturing and sales are subject to changes
in foreign political and economic conditions, and to other typical risks of
doing business internationally. For example, China is the primary market for VCD
and Chaoji VCD players utilizing C-Cube's decoder products. As a consequence,
any political or economic instability in China could significantly reduce demand
for its products. C-Cube has made and will continue to make significant
                                        77
   83

investments in additional chip manufacturing capacity in Taiwan and is subject
to the risk of political instability in Taiwan, including but not limited to the
potential for conflict between Taiwan and the People's Republic of China. C-Cube
sells products to customers in Korea and is subject to the risk of economic and
political instability in Korea, including the potential for conflict between
North and South Korea. In addition, C-Cube sells certain of its products in
international markets and buys certain products from its chip manufacturing
facilities in currencies other than the U.S. dollar. As a result, currency
fluctuations could, in the long term, have an adverse effect on C-Cube's
business and results of operations.

     With respect to international sales that are denominated in U.S. dollars,
increases in the value of the U.S. dollar relative to foreign currencies can
increase the effective price of, and reduce demand for, C-Cube's products
relative to competitive products priced in the local currency. The United States
has considered trade sanctions against Japan and has had disputes with China
relating to trade and human rights issues. If trade sanctions were imposed,
Japan or China could enact trade sanctions in response. Because a number of
C-Cube's current and prospective customers and suppliers are located in Japan
and China, trade sanctions, if imposed, could have an adverse effect on its
business and results of operations. Similarly, protectionist trade legislation
in either the United States or foreign countries could have an adverse effect on
C-Cube's ability to manufacture or sell its products in foreign markets.

     The Asian consumer electronics markets accounted for approximately 60%, 67%
and 74% of C-Cube's total sales in 2000, 1999 and 1998, respectively. Asia sales
are expected to continue to account for a substantial, though declining,
percentage of sales in the future. Most of C-Cube's sales in Asia were of
decoder chips, which are used in VCD and Chaoji VCD players. C-Cube believes
purchases of VCD and Chaoji VCD players are not as likely to be deferred as are
purchases of higher priced consumer durables and production equipment, which
have impacted U.S. export sales. However, C-Cube may experience reduced sales of
its products into Asia because of declining consumer spending or because of its
customers' increasing difficulty in obtaining letters of credit, which C-Cube
generally requires prior to shipment.

MANUFACTURING

     C-Cube has chosen to use independent chip manufacturing facilities, called
foundries, to fabricate its integrated circuits. Assembly, test and packaging
are also subcontracted to third parties. This approach enables C-Cube to
concentrate its resources on product design and development, where it believes
it has greater competitive advantages. C-Cube continually evaluates alternative
sources for chip manufacturing, assembly and test capacity.

     During 2000, C-Cube's devices were fabricated using advanced process
technology with 0.5 micron, 0.35 micron, 0.30 micron, 0.25 micron and 0.18
micron process feature sizes, using either three, four or five layers of metal
interconnect. Fabricated chips are tested by the fabrication facility to
C-Cube's specifications. Once the chips are fully tested and accepted, the dice
are assembled into packages by subcontractors, primarily located in Asia. C-Cube
utilizes multiple assembly subcontractors for its products.

     In 1996, C-Cube expanded and formalized its relationship with Taiwan
Semiconductor Manufacturing Co., Ltd., or TSMC, to provide chip production
capacity in the years 1996 to 2003. C-Cube prepaid $24.5 million to TSMC and in
return, TSMC provided that they would produce and sell chips to C-Cube at
specified prices. If C-Cube meets its minimum guaranteed purchase volume each
year, TSMC applies a portion of the prepayment against a portion of the chip
cost. Accordingly, the prepaid amount, which has been allocated between current
and long-term assets, is amortized to inventory as chips are received. In the
event that C-Cube does not meet the minimum committed volume in a given year and
the volume cannot be filled by TSMC or assigned to another company, the
prepayment assigned to that year could be forfeited. At December 31, 2000,
remaining production capacity rights were $5.7 million dollars of which $2.1
million was included in other current assets and $3.6 million was classified as
a non-current asset.

     During the fourth quarter of 1999, C-Cube signed a production capacity
agreement with United Microelectronics Corporation to provide chip production
capacity in the years 2000 through 2002, for which C-Cube paid a $20.0 million
refundable payment in the first quarter of 2000. This refundable payment,
classified as a current asset, allows for certain discounts on purchased
capacity based upon the

                                        78
   84

quantities purchased. The agreement does not commit C-Cube to purchase chips,
but does guarantee the availability of a set capacity of chips at "not to
exceed" prices.

     C-Cube believes that an increase in the demand for its chips over currently
expected levels, or a failure of manufacturing capacity in the industry to grow
at anticipated rates, could result in greater difficulty in obtaining adequate
manufacturing capacity, increased prices and increased lead times. C-Cube's
future operating results depend in substantial part on its ability to increase
the capacity available to it from its existing or new chip manufacturing
facilities. In order to secure such capacity, C-Cube has considered and will
continue to consider various possible transactions, which could include, without
limitation:

     - equity investments in, prepayments to, non-refundable deposits with or
       loans to chip manufacturing facilities in exchange for guaranteed
       capacity;

     - take or pay contracts that commit C-Cube to purchase specified quantities
       of chips over extended periods;

     - joint ventures; or

     - other partnership relationships with chip manufacturing facilities.

     C-Cube sources its integrated circuit products from United Microelectronics
Corporation and Taiwan Semiconductor Manufacturing Co., Ltd. This dependence on
a small number of chip manufacturing facilities subjects C-Cube to risks
associated with an interruption in supply from these chip manufacturing
facilities. In connection with the manufacture of its newer products, C-Cube
needs to continue to evaluate and qualify additional chip manufacturing
facilities that employ advanced manufacturing and process technologies, which
are currently available from a limited number of chip manufacturing facilities.
For example, certain of the new products that C-Cube intends to introduce
require advanced process technology. C-Cube has in the past experienced
increased costs and delays in connection with the qualification of new chip
manufacturing facilities.

     C-Cube's reliance on subcontractors to manufacture and assemble its
products involves significant risks, including reduced control over:

     - delivery schedules;

     - quality assurance;

     - manufacturing yields and cost;

     - the potential lack of adequate capacity; and

     - potential misappropriation of C-Cube's intellectual property.

     C-Cube obtains manufacturing capacity through forecasts that are generated
in advance of expected delivery dates. C-Cube's ability to obtain the
manufacturing capacity necessary to meet the future demand for its products is
based on its ability to accurately forecast such future demand. If C-Cube fails
to accurately forecast such future demand, it may be unable to timely obtain an
adequate supply of chips necessary to manufacture the number of products
required to satisfy the actual demand.

     The markets into which C-Cube sells its products are subject to extreme
price competition. Thus, C-Cube expects to continue to experience declines in
the selling prices of its products over the life cycle of each product. In order
to offset or partially offset declines in the selling prices of its products,
C-Cube must continue to reduce the costs of products through product design
changes, manufacturing process changes, volume discounts, yield improvements and
other savings negotiated with its manufacturing subcontractors. Since C-Cube
does not operate its own manufacturing facilities and must make volume
commitments to subcontractors at prices that remain fixed over certain periods
of time, C-Cube may not be able to reduce its costs as rapidly as its
competitors who perform their own manufacturing. C-Cube's failure to design and
introduce, in a timely manner, lower cost versions of existing products or new

                                        79
   85

products with higher gross margins, or to successfully manage C-Cube's
manufacturing subcontractor relationships would have a material adverse effect
on its gross margins.

COMPETITION

     C-Cube believes that it competes favorably in the areas of:

     - product definition;

     - system cost;

     - functionality;

     - time-to-market;

     - reliability; and

     - reputation.

     C-Cube competes with major domestic and international companies, most of
which have substantially greater financial and other resources than C-Cube with
which to pursue engineering, manufacturing, marketing and distribution of their
products. Some of these companies own proprietary video compression technology
competitive with C-Cube's standards-based systems.

     In the market for consumer electronics semiconductors, C-Cube's principal
competitors include:

     - Broadcom;

     - ESS Technology;

     - ST-Microelectronics;

     - LSI Logic;

     - IBM;

     - Sony;

     - National Semiconductor;

     - Philips Semiconductor; and

     - Zoran.

     IBM is C-Cube's principal competitor in the broadcast encoder market, while
Sony is C-Cube's principal competitor in the consumer encoder market. C-Cube
expects that other companies will introduce competing encoder products in the
future. Although the timing of the production availability of such encoders is
uncertain, their availability could have an adverse impact on C-Cube's encoder
product revenues and margins. C-Cube may also face increased competition in the
future from new entrants into its markets. As the markets for its products
develop, competition from large semiconductor companies, such as
ST-Microelectronics and Philips, and from vertically integrated companies such
as Sony, MEC, Toshiba and NEC, may increase significantly. If C-Cube can offer
low-cost hardware solutions, then it may continue to compete with manufacturers
of general-purpose microprocessors such as Intel, AMD and Motorola in
conjunction with software solutions. C-Cube's ability to compete successfully in
the rapidly evolving markets for high-performance video compression technology
depends on factors both within and outside of its control, including:

     - success in designing and subcontracting the manufacture of new products
       that implement new technologies, adequate sources of raw materials;

     - protection of C-Cube's products by effective utilization of intellectual
       property laws;

     - product quality;

                                        80
   86

     - reliability;

     - price and the efficiency of production;

     - the pace at which customers incorporate C-Cube's integrated circuits into
       their products or technologies;

     - success of competitors' products; and

     - general economic conditions.

     A variety of other hardware and software solutions to digital video
compression have been introduced. Competitor companies are designing products
around these and other alternative approaches. In addition, manufacturers of
general-purpose microprocessors, such as Intel, AMD and Motorola and graphics
chip manufacturers are positioning their products as offering the capacity to
compress digital video into a more compact form. C-Cube does not know whether
system manufacturers will use such processors for video compression
applications. While MPEG has become the accepted standard, any of the
alternative approaches, individually or collectively, could be adopted on a
widespread basis in the emerging video compression market. If this were to
happen, C-Cube's business and results of operations would be materially and
adversely affected.

INTELLECTUAL PROPERTY AND LICENSES

     As of December 31, 2000, C-Cube had 84 issued U.S. patents and 21 U.S.
patent applications pending and has filed certain corresponding applications in
certain foreign jurisdictions. These patents expire on various dates from 2010
to 2020. C-Cube intends to continue to seek patents on C-Cube's technology where
appropriate. Notwithstanding its patent position, C-Cube believes that, in view
of the rapid pace of technological change in the semiconductor industry, the
technical experience and creative skills of its engineers and other personnel
are the most important factors in determining its future technological success.
Moreover, while C-Cube holds or has applied for patents relating to the design
of its products, its products are based in part on standards and C-Cube does not
hold patents or other intellectual property rights for such standards.

     In order to defray the cost of developing C-Cube's products and to develop
products with specifications meeting customer requirements, C-Cube has
established development relationships with certain companies. Under these
arrangements, these companies provided C-Cube with development funding and/or
technical assistance, and participated with C-Cube in determining the
specifications for the performance requirements of various products. As a result
of these relationships, C-Cube believes it has been able to more rapidly
introduce products meeting the demands of these as well as other customers for
similar applications. In certain cases, as consideration for such development
assistance, C-Cube has agreed to pay royalties to such customers and generally
it retains ownership of such products.

PROPERTY

     C-Cube's principal facilities consist of approximately 215,000 square feet
of space in three buildings located in Milpitas, California. This space is
leased under three leases that expire on various dates through July 31, 2007.
C-Cube believes its existing facilities and other available facilities will be
adequate to meet its requirements for at least the next 12 months.

LEGAL PROCEEDINGS

     C-Cube has been named as a defendant in a securities class-action complaint
filed in the United States district court for the northern district of
California. The plaintiffs in the action purport to represent the class of all
persons who purchased common stock between January 19, 2000 and May 3, 2000 in
the entity then known as C-Cube Microsystems. The complaint alleges that C-Cube
is liable for the acts and statements for the entity then known as C-Cube
Microsystems prior to May 3, 2000, even though C-Cube

                                        81
   87

did not legally exist prior to May 3, 2000. The case is in its early stages and
C-Cube believes that the allegations contained in the complaint are without
merit and intends to defend the action vigorously.

     From time-to-time C-Cube is party to certain other litigation or legal
claims. Management has reviewed all additional pending legal matters and
believes that the resolution of such additional matters will not have a
significant adverse effect on C-Cube's financial position or results of
operations.

EMPLOYEES

     As of December 31, 2000, C-Cube had approximately 588 employees, 257 of
whom are engaged in, or directly support, its research and development, 214 of
whom are in sales and marketing, 38 of whom are in operations and 79 of whom are
in administration. C-Cube's employees are not represented by any collective
bargaining agreement, and it has never experienced a work stoppage. C-Cube
believes its employee relations are good.

     C-Cube's future success is heavily dependent upon its ability to hire and
retain qualified technical, marketing and management personnel. C-Cube is
currently seeking certain additional engineering, marketing and management
personnel. C-Cube's success in the future will depend in part on the successful
assimilation of such new personnel. C-Cube also obtains assistance from
customers whose engineers participate in its development programs. The
continuing availability of such support is dependent upon a number of factors,
including relationships with customers and the ability of such engineers, many
of whom are foreign residents, to obtain immigration visas.

     MERGER/SPIN-OFF

     C-Cube entered into an Amended and Restated Agreement and Plan of Merger
and Reorganization with Harmonic Inc. on December 9, 1999. In accordance with
this agreement, in May 2000, C-Cube's semiconductor division was spun-off as
C-Cube Semiconductor Inc. to the stockholders of C-Cube Microsystems Inc. as an
independent company and C-Cube Microsystems Inc., consisting primarily of its
DiviCom division, was merged with Harmonic Inc. C-Cube Semiconductor Inc. was
then renamed C-Cube Microsystems Inc., with the approval of Harmonic Inc., to
maintain customer continuity and the brand identity of C-Cube's semiconductor
products. The transaction was accounted for as if the semiconductor division
were the continuing entity. Accordingly, as required by Accounting Principles
Board Opinion No. 30 and Emerging Issues Task Force Issue No. 95-18, the results
of operations of the semiconductor division (the continuing entity) are reported
separately from the results of operations of the DiviCom division (the
discontinued entity). The results of operations in prior periods have been
restated and certain prior period amounts have been reclassified to conform to
the current period presentation. These restatements and reclassifications had no
effect on net income or stockholders' equity.

                                        83
   89

     The results of discontinued operations are presented on two line items on
the face of the Consolidated Statements of Operations. For the current year,
loss from operations of DiviCom represents the net loss of DiviCom operations
through the date of merger of $10.1 million. Revenues and tax benefit for 2000
through the date of merger were $36.8 million and $6.8 million, respectively.
Revenues and taxes for the year ended December 31, 1999 were $185.5 million and
$10.2 million respectively. Loss on disposal of DiviCom includes direct costs,
net of taxes, associated with the merger/spin-off transaction which were
incurred by C-Cube.

     In connection with the merger, C-Cube transferred the net assets of DiviCom
to Harmonic incurred a tax liability in connection with the spin-off of the
semiconductor business and recorded a deferred tax asset relating to an increase
in the tax basis of C-Cube's assets. The transfer of the net assets and the tax
liability have been reflected as a return of capital to the stockholders. In
connection with the merger, C-Cube entered into a tax sharing agreement with
Harmonic under which C-Cube assumed liability for income and other taxes
incurred prior to and as a result of the spin-off.

     PRODUCTION CAPACITY AGREEMENTS

     In the fourth quarter of 1999, C-Cube signed a production capacity
agreement with United Microelectronics Corporation, or UMC, to provide chip
production capacity in the years 2000 to 2002, for which it paid a $20.0 million
refundable payment in January 2000, classified as a non-current asset. This
deposit earns interest at 4% per year, allows for certain discounts on purchased
capacity based upon the quantities purchased and is refundable after 90 days'
notice by C-Cube. The agreement does not commit C-Cube to purchase chips, but
does guarantee the availability of a set capacity of chips at "not to exceed"
prices.

     In the second quarter of 1996, C-Cube expanded and formalized its
relationship with Taiwan Semiconductor Manufacturing Co., Ltd., or TSMC, to
provide wafer production capacity in the years 1996 to 2001. The agreement with
TSMC provided that TSMC would produce and ship wafers to C-Cube at specified
prices and required C-Cube to make two advance payments totaling $49.0 million.
An advance payment of $24.5 million was made in June 1996. In May 1997, C-Cube
amended its agreement with TSMC which resulted in a reduction of its future
wafer purchase commitments and the forgiveness of the second advance payment of
$24.5 million. In January 1999, C-Cube signed a second amendment to its
agreement with TSMC which resulted in a refund to C-Cube of $11.7 million and an
extension of the term of the agreement to 2003. Advance payments associated with
wafer production capacity rights are amortized over the shorter of the contract
period or the actual delivery of wafers in relation to the minimum number of
wafers to be purchased under the agreement. At December 31, 2000, remaining
production capacity rights were $5.7 million, of which $2.1 million was included
in other current assets and $3.6 million was classified as a non-current asset.

     NET REVENUES

     Net revenues increased 19.3% to $265.0 million in 2000 compared to $222.1
million in 1999. This increase was led by strong set-top box sales, primarily
for European deployments. Codec sales also increased because of increasing
DVxpert and DVxpress volumes. Because of higher volume shipments, sales from DVD
chips used in consumer applications increased significantly despite price
reductions due to increased competition. Overall DVD growth was slowed by
significantly reduced volumes of chips used in DVD PCs. The increases discussed
above were largely offset by reductions in VideoCD and S-VCD decoder chip
revenues due to reduced shipments and increased price competition.

     In 1999, net revenues increased 6.2% to $222.1 million compared to $209.1
million in 1998. C-Cube's revenues increased slightly over 1998; however, the
product mix changed significantly. Revenues from DVD decoder chips used in
consumer applications increased significantly due to higher volume shipments,
despite price reductions resulting from increased competition. Revenues from
encoder and codec chipsets for set-top, broadcast and non-linear editing
applications increased due to higher volume shipments. The

                                        84
   90

increases discussed above were largely offset by reductions in VideoCD and S-VCD
decoder chip revenues due to reduced shipments and increased price competition.

     The sales returns allowance at December 31, 2000 was $1.6 million,
decreasing from $3.0 million at December 31, 1999. During 2000, additions to the
sales returns allowance were $100,000 and deductions were $1.5 million. The
deductions to the allowance were primarily due to price protection credits and
other pricing adjustments.

     The sales returns allowance at December 31, 1999 was $3.0 million,
decreasing from $4.7 million at December 31, 1998. During 1999, no additions
were made to the sales returns allowance and deductions were $1.7 million. The
deductions to the allowance were primarily due to product returns from
customers.

     In 2000, sales to two customers were $29.9 million and $28.1 million, each
more than 11% of C-Cube's revenues. In 1999 no customer accounted for 10% or
more of net revenues. In 1998, one of C-Cube's customers accounted for $21.9
million, or 10%, of its 1998 revenues.

     International revenues accounted for 87.1%, 82.3% and 81.7% of net revenues
in 2000, 1999 and 1998, respectively. International revenues were a significant
portion of C-Cube's total revenues primarily due to volume shipments of DVD,
VideoCD and S-VCD players into Asia and an increase in set-top sales into
Europe. C-Cube sells products and supports customers internationally through
subsidiaries and sales offices located in Canada, China, France, Japan, Korea,
Taiwan and the United Kingdom. C-Cube expects that international revenues will
continue to represent a significant portion of net revenues. C-Cube's
international sales and manufacturing are subject to changes in foreign
political and economic conditions and to other risks, including fluctuations in
foreign exchange rates, export/import controls and changes in tax laws, tariffs
and freight rates. See "Information Relating to C-Cube -- International Business
Activities."

     GROSS MARGIN

     C-Cube's gross margin percentage decreased to 54.9% in 2000 from 60.3% in
1999. This decline was principally attributable to a change in its product mix
as well as declines in the average selling price in the DVD, S-VCD and VCD
markets without similar manufacturing cost reductions. C-Cube's gross margin
percentage increased to 60.3% in 1999 from 59.0% in 1998. This increase was
primarily the result of changes in product mix, as the volume of sales of
products with higher gross margins, including encoders, DVD decoders and digital
set-top boxes. Additionally, C-Cube was able to offset the related impact on
gross margin by realizing greater operating efficiencies, including reduced
material costs, refinement of its semiconductor design process and the reduction
of outside manufacturing costs.

     The markets into which C-Cube sells its semiconductor products are subject
to extreme price competition. Therefore, while C-Cube expects that any new
products C-Cube may introduce could offset the decline in the average selling
price for established products, C-Cube continues to experience declines in the
selling prices of its semiconductor products over the life cycle of each
product. In particular, C-Cube expects to continue to experience significant
price competition in the markets for decoder chips. In order to offset or
partially offset declines in the selling prices of its products, C-Cube must
continue to reduce the costs of products through product design changes,
manufacturing process changes, volume discounts, yield improvements and other
savings negotiated with its manufacturing subcontractors. Since C-Cube does not
believe that it can continually achieve cost reductions which fully offset the
price declines of its products, C-Cube expects gross margin percentages to
decline for existing products over their life cycles.

     C-Cube does not own its manufacturing facilities and must make volume
commitments to subcontractors at prices that remain fixed over certain periods
of time. Therefore, it may not be able to reduce its costs as rapidly as its
competitors who perform their own manufacturing. C-Cube's failure to design and
introduce in a timely manner lower cost versions of existing products or higher
gross margin new products, or to successfully manage its manufacturing
subcontractor relationships, could have a material adverse effect on its gross
margins.

     RESEARCH AND DEVELOPMENT EXPENSES

     In 2000, research and development expenses were $72.2 million or 27.2% of
net revenues, compared to $54.3 million or 24.4% of net revenues in 1999. The
majority of the increase from 1999 resulted from the issuance of warrants to
Thomson Multimedia S.A., whereby C-Cube recorded $12.6 million of research and
development expense.

     In 1999, research and development expenses were $54.3 million or 24.4% of
net revenues, compared to $52.8 million or 25.3% of net revenues in 1998
primarily related to an increase in employee-related costs associated with
increases in product engineering staff, in addition to increases in costs for
development tools and non-recurring engineering. The increase in headcount
reflects C-Cube's continuing efforts to provide industry leading digital video
solutions at the chip level.

     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES

     Selling, general and administrative expenses increased to $68.3 million or
25.8% of net revenues in 2000 compared to $37.2 million or 16.8% of net revenues
in 1999. The increase from 1999 is primarily related to stock-based compensation
and merger/spin-off related payroll taxes totaling $20.8 million. In connection
with the merger and spin-off, C-Cube recorded stock-based compensation expense,
of $15.5 million related to the accelerated vesting of options for certain of
its employees. As a condition of the Amended and Restated Agreement and Plan of
Merger and Reorganization with Harmonic Inc., all vested employee stock options
were to be exercised before the merger date or they would be forfeited. The
resulting exercises generated an additional payroll tax expense, within selling,
general and administrative, of $5.3 million. To a lesser extent expenses
increased as management and infrastructure were no longer shared with DiviCom.
The increase in sales and marketing headcount reflects C-Cube's efforts to
increase its international presence.

     Selling, general and administrative expenses increased to $37.2 million or
16.8% of net revenues in 1999 compared to $36.3 million or 17.4% of net revenues
for 1998. The increase in absolute dollars from 1998 was primarily due to
increased travel, staffing and related expenses partially offset by decreased
commissions to distributors. C-Cube expects that absolute levels of selling,
general and administrative expenses will continue to increase in future periods.

     OTHER INCOME (EXPENSE)

     Interest and other income increased to $11.0 million in 2000 compared to
$10.7 million in 1999 primarily due to $4.6 million of gains on the sale of
investments, partially offset by lower average balances of cash and investments
in 2000 compared to 1999. Interest income and other increased to $10.7 million
in 1999 compared to $10.2 million in 1998 primarily due to higher average
balances of cash and investments in 1999 compared to 1998. Interest and other
expense increased to $3.2 million in 2000 compared to $1.5 million in 1999
primarily due to an outstanding line of credit facility in 2000. Interest
expense and other decreased to $1.5 million in 1999 compared to $4.2 million in
1998 primarily due to lower average outstanding debt balances due to the
repurchase of a significant portion of C-Cube's convertible subordinated notes.

     INCOME TAX EXPENSE

     C-Cube provided $3.4 million for income taxes in 2000 on income before
taxes, minority interest and extraordinary items of $12.8 million, for an
effective tax rate of 26.6%. In 1999, C-Cube provided $14.6 million for income
taxes on income before taxes, minority interest and extraordinary items of $51.6
million, for an effective tax rate of 28.3%. In 1998, C-Cube provided $9.8
million for income taxes on income before taxes and minority interest of $36.7
million, for an effective tax rate of 26.7%. The effective tax rates for 2000,
1999 and 1998 are less than the combined federal and state statutory rate
primarily due to tax credits and lower foreign taxes.

                                        86
   92

     EXTRAORDINARY ITEM

     During 1998, C-Cube repurchased $63.5 million of the face value of its
5.875% subordinated convertible notes due 2005 (the "notes") at 88.4% of the
principal amount, with accrued interest to the date of repurchase, and
recognized an extraordinary gain of $3.5 million, or $0.09 per diluted share,
net of related income taxes of $2.4 million.

     FACTORS THAT MAY AFFECT FUTURE RESULTS

     C-Cube's quarterly and annual operating results have been and will continue
to be affected by a wide variety of factors that could have a material adverse
effect on revenues and profitability during any particular period, including its
ability to introduce new products and technologies on a timely basis,
unanticipated problems in the performance of C-Cube's next-generation or
cost-reduced products, the rescheduling or cancellation of orders by its
customers, competitive pressures on selling prices, changes in product or
customer mix, availability and cost of foundry capacity and raw materials,
fluctuations in yield, loss of any strategic relationships, the ability to
successfully introduce products in accordance with OEM design requirements and
design cycles, new product introductions by its competitors, market acceptance
of products of both C-Cube and its customers, compatibility of new products with
emerging digital video standards, purchase commitments for customized components
procured in advance of anticipated systems contracts, supply constraints for
other components incorporated into its customers' products, credit risk for
international customers not using letters of credit, fluctuations in foreign
currency exchange rates to the U.S. dollar, the level of expenditures in
manufacturing, research and development, and sales, general and administrative
functions, and a recent trend of mergers and acquisitions creating larger
competitors which may have established market share or greater financial or
technical resources than C-Cube.

     In addition, C-Cube's operating results are subject to fluctuations in the
markets for its customers' products, particularly the consumer electronics
market, which has been extremely volatile in the past, and the digital satellite
broadcast, cable and wireless cable markets, which are in an early stage,
creating uncertainty with respect to product volume and timing. To the extent
C-Cube is unable to fulfill its customers' purchase orders on a timely basis,
these orders may be canceled due to changes in demand in the markets for its
customers' products. A significant portion of C-Cube's expenses are fixed in the
short term, and the timing of increases in expenses is based in large part on
its forecast of future revenues. As a result, if revenues do not meet its
expectations, C-Cube may be unable to quickly adjust expenses to levels
appropriate to actual revenues, which could have a material adverse effect on
its business and results of operations.

     C-Cube's dependence on the Chinese consumer electronics market has started
to decline, and C-Cube believes it will either remain stable or decline in the
future, as growth in the encoder, digital satellite broadcast, non-linear
editing, digital cable and wireless cable markets generate larger contributions
to revenues. Nevertheless, the substantial seasonality of sales in the consumer
electronics market could impact C-Cube's revenues and net income. In particular,
C-Cube believe that there may be seasonality in the Asia-Pacific region related
to the Chinese New Year, which falls within the first calendar quarter, which
could result in relatively lower product demand during the second and third
quarters of each year. If in the future the geographic mix of C-Cube's sales
shifts towards the U.S. and Europe, it would anticipate higher revenues and net
income in the third and fourth calendar quarters as system manufacturers in
these regions make purchases in preparation for the holiday season, and
comparatively less revenues and net income in the first and second calendar
quarters.

     As a result of the above, C-Cube's operating results and stock price may be
subject to significant volatility, particularly on a quarterly basis. Any
shortfall in net revenues or net income from levels expected by securities
analysts could have an immediate and significant adverse effect on the trading
price of C-Cube's common stock.

     The market price of C-Cube's common stock has fluctuated significantly
since the merger/spin-off in May 2000. The market price of C-Cube's common stock
could be subject to significant fluctuations in the future based on factors such
as merger or acquisition activity, announcements of new products by C-Cube
                                        87
   93

or its competitors, quarterly fluctuations in its financial results or other
semiconductor and digital video networking industries, conditions in the
financial markets and general conditions in the global economy which might
adversely affect consumer purchasing. In addition, the stock market in general
has experienced extreme price and volume fluctuations, which have particularly
affected the market prices for many high technology companies and which have
often been unrelated to the operating performance of the specific companies.

LIQUIDITY AND CAPITAL RESOURCES

     Cash, cash equivalents and short-term investments decreased to $52.5
million at December 31, 2000 from $290.5 million at December 31, 1999. Working
capital decreased to $30.9 million at December 31, 2000 from $283.8 million at
December 31, 1999.

     C-Cube's operating activities provided cash of $17.2 million in 2000,
compared to $40.2 million in 1999. This is primarily from a warrant issuance of
$12.6 million and an increase in accrued liabilities of $12.0 million.

     In C-Cube's investing activities, sales and maturities of short-term
investments provided cash of $173.1 million and purchase of short-term
investments used cash of $3.0 million. C-Cube also used cash of $20.0 million to
secure production capacity rights.

     Cash used by financing activities was $233.4 million, primarily due to
income tax paid on the spin-off of DiviCom using cash of $431.4 million, the tax
benefit from employee stock transactions of $86.2 million, partially offset by
$110.8 million provided by common stock issued under stock plans.

     As of December 31, 2000, C-Cube had a $27.0 million bank line of credit
($27.0 million outstanding at December 31, 2000) that expires on May 31, 2002.
The first $6.0 million of borrowed funds bear interest at LIBOR plus 2.0% (8.4%
at December 31, 2000), with additional borrowings bearing interest at the bank's
prime rate (9.5% at December 31, 2000). The line of credit agreement requires
that C-Cube, among other things, maintain a minimum tangible net worth and
certain financial ratios and is collateralized by its current assets. At
December 31, 2000, C-Cube was not in compliance with one of its covenants. The
bank has waived compliance with this requirement for the fiscal year ended
December 31,2000.

     On January 4, 2001, the line of credit was revised. Under the terms of the
revised line of credit agreement, $22.0 million bears interest at LIBOR plus 2%
(8.4% as of January 4, 2001) and $5.0 million bears interest at the bank's prime
rate (9.0% as of January 04, 2001), with all other loan terms remaining the
same.

     As discussed earlier, C-Cube has a wafer production capacity agreement with
Taiwan Semiconductor Manufacturing Co., Ltd., or TSMC. In January 1999, C-Cube
signed a second amendment to its agreement with TSMC which resulted in a refund
to C-Cube of $11.7 million. In the fourth quarter of 1999, C-Cube entered into a
wafer production capacity agreement with United Microelectronics Corporation,
for which it paid a refundable deposit of $20.0 million in January 2000.

     Based on current plans and business conditions, C-Cube expects that its
cash, cash equivalents and short-term investments together with any amounts
generated from operations and available borrowings, will be sufficient to meet
its cash requirements for at least the next 12 months. However, C-Cube may be
required to seek other financing sooner and such financing, if required, will be
available on terms satisfactory to C-Cube. In addition, C-Cube has considered
and will continue to consider various possible transactions to secure additional
foundry capacity, which could include, without limitation, equity investments
in, prepayments to, non-refundable deposits with or loans to foundries in
exchange for guaranteed capacity, "take or pay" contracts that commit C-Cube to
purchase specified quantities of wafers over extended periods, joint ventures or
other partnership relationships with foundries.

NEW ACCOUNTING PRONOUNCEMENTS

     In December 1999, the Securities and Exchange Commission issued Staff
Accounting Bulletin No. 101, or "SAB 101," "Revenue Recognition," which provides
guidance on the recognition, presentation and disclosure of revenue in financial
statements filed with the Securities and Exchange Commission. SAB 101 outlines
the basic criteria that must be met to recognize revenue and provides guidance
for disclosures related to revenue recognition policies. SAB 101 is effective
for the fiscal quarter beginning October 1, 2000. The adoption of SAB 101 did
not have a material impact on the consolidated financial statements.

     In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standard No. 133, or "SFAS 133", "Accounting for Derivative
Instruments and Hedging Activities," which establishes accounting and reporting
standards for derivative instruments, including certain derivative instruments
embedded in other contracts, and for hedging activities. It requires that an
entity recognize all derivatives as either assets or liabilities in the
statement of financial position and measure those instruments at fair value.
SFAS 133 is effective for fiscal years beginning after June 15, 2000. C-Cube
adopted SFAS 133 on January 1, 2001. The adoption of this statement did not have
a material impact on the consolidated financial statements.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     The following discussion about C-Cube's market risk disclosures involves
forward-looking statements. Actual results could differ materially from those
projected in the forward-looking statements. C-Cube is exposed to market risk
related to changes in interest rates and foreign currency exchange rates. C-Cube
does not use derivative financial instruments for speculative or trading
purposes.

     INTEREST RATE SENSITIVITY

     C-Cube maintains a short-term investment portfolio consisting mainly of
U.S. Government agencies and debt securities with an average maturity of less
than one year. The market value of this portfolio was $2.8 million at December
31, 2000. These available-for-sale securities are subject to interest rate risk
and will fall in value if market interest rates increase. If market interest
rates were to increase immediately and uniformly by 10% from current levels at
December 31, 2000, the fair value of the portfolio would not be affected
materially. C-Cube has the ability to hold its fixed income investments until
maturity, and therefore it would not expect its operating results or cash flows
to be affected to any significant degree by the effect of a sudden change in
market interest rates on its securities portfolio. C-Cube does not hedge any
interest rate exposures.

     C-Cube has fixed rate long-term debt of approximately $1.3 million, and a
hypothetical 10% increase or decrease in current interest rates from levels at
December 31, 2000 would not have a material impact on the fair market value of
this debt.

     FOREIGN CURRENCY EXCHANGE RISK

     C-Cube enters into foreign exchange forward contracts to hedge certain
economic exposures, balance sheet exposures and inter-company balances against
future movements in the dollar/yen exchange rates. Gains and losses on the
forward contracts are largely offset by gains and losses on the underlying
exposure. A hypothetical 10% appreciation of the U.S. dollar from December 31,
2000 market rates would increase the unrealized value of C-Cube's forward
contracts by $400,000. Conversely, a hypothetical 10% depreciation of the U.S.
dollar from December 31, 2000 market rates would decrease the unrealized value
of its forward contracts by $400,000. In either scenario, the gains or losses on
the forward contracts are largely offset by the gains or losses on the
underlying transactions and consequently a sudden or significant change in
foreign exchange rates would not be expected to have a material impact on future

                     UNAUDITED PRO FORMA COMBINED CONDENSED
                              FINANCIAL STATEMENTS

     The following unaudited pro forma combined condensed financial information
combines LSI Logic's and C-Cube's historical audited consolidated financial
statements for the twelve months ended December 31, 2000, giving effect to the
merger as if it had occurred as of the beginning of the period for the statement
of operations and as of December 31, 2000 for the balance sheet. The unaudited
pro forma combined condensed financial statements are presented for illustrative
purposes only and are not necessarily indicative of the consolidated financial
position or results of operations for future periods or the results that
actually would have been realized had LSI Logic and C-Cube been a consolidated
company during the periods presented. The unaudited pro forma combined condensed
financial statements, including the notes thereto, are qualified in their
entirety by reference to, and should be read in conjunction with the historical
consolidated financial statements and the notes thereto of LSI Logic which were
previously reported in LSI Logic's Annual Report on Form 10-K for the year ended
December 31, 2000, which are hereby incorporated by reference, and the
consolidated financial statements and the notes thereto for the year ended
December 31, 2000 of C-Cube included elsewhere in this prospectus.

     The following unaudited pro forma combined condensed financial statements
give effect to the merger of LSI Logic and C-Cube using the purchase method of
accounting and the assumptions and adjustments described below. The allocation
of the purchase price will be finalized following completion of the merger and
finalization of independent appraisals to determine the fair value of tangible
and identifiable intangible assets, including in-process research and
development. Based on an analysis of fair value, the excess of the purchase
price over the fair value of net tangible assets on C-Cube's balance sheet will
then be allocated to identifiable intangible assets and goodwill. LSI Logic is
currently in the process of obtaining the data necessary to determine the fair
value of tangible and identifiable intangible assets, including in-process
research and development. For both in-process and developed technology, LSI
Logic is focused on determining C-Cube's forecasted revenues and costs as well
as their stage of completion or remaining product life by individual project or
product. The types of projects in process relate to digital set-top box, DVD and
CODEC-based applications such as personal video recording, home media servers,
recordable DVD, residential gateway and streaming video.

     The total estimated amount of goodwill and identified intangible assets is
$647 million with an estimated average useful life of approximately six years.
Because the valuation has not been completed, the actual amount of goodwill and
identifiable intangible assets, and the related average useful life, could vary
from these estimates.

NOTE 1. BASIS OF PRESENTATION

     On March 26, 2001, LSI Logic signed a definitive merger agreement ("merger
agreement") to acquire C-Cube in a transaction to be accounted for as a
purchase. In accordance with the merger agreement, LSI Logic has agreed to
commence an exchange offer whereby it will offer 0.79 of a share of LSI Logic
common stock for each outstanding share of C-Cube common stock. Under the terms
of the merger agreement, the exchange offer will be followed by a merger in
which LSI Logic would acquire, at the same exchange ratio, the remaining shares
of C-Cube common stock not previously acquired in the exchange offer. Upon
completion of the merger, LSI Logic has agreed to assume all outstanding options
and warrants to purchase C-Cube common stock and convert them into options and
warrants to purchase shares of LSI Logic common stock. The merger is subject to
customary closing conditions, including the tender for exchange of at least a
majority of C-Cube's outstanding shares of common stock (including for purposes
of the calculation of the majority of shares, certain outstanding options and
warrants to purchase C-Cube shares) and the expiration or termination of the
waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act and
applicable foreign antitrust laws.

     The purchase price of the C-Cube acquisition has been estimated to be
approximately $897 million, which has been determined as follows (in thousands):


                                                         
Value for common shares issued............................  $740,987
Fair value of options assumed.............................   133,448
Fair value of warrants assumed............................     8,283
Estimated direct acquisition costs........................    14,143
                                                            --------
  Total purchase price....................................  $896,861
                                                            ========


     LSI Logic has agreed to issue approximately 39.6 million shares of its
common stock, 12.5 million options and 0.8 million warrants in exchange for the
outstanding common shares, options and warrants of C-Cube, respectively. This
data is based upon C-Cube outstanding shares on the date the merger agreement
was signed. The exact number of shares, options and warrants to be issued for
the purchase of C-Cube will be affected by option grants to new C-Cube employees
and exercises of currently outstanding options and warrants, and, therefore, the
final purchase price will be different from the amounts presented in these
unaudited pro forma combined condensed financial statements.

     Common stock has been valued using an average price of LSI Logic common
stock for a few days before and after the announcement of the merger. The fair
value of the options and warrants assumed was determined using the Black-Scholes
method. In accordance with FASB Interpretation No. 44 ("FIN 44"), "Accounting
for Transactions Involving Stock Compensation -- an Interpretation of APB 25,"
that portion of the intrinsic value of unvested options of C-Cube relating to
the vesting period following completion of the transaction has been allocated to
deferred stock compensation. Deferred stock compensation will be amortized over
the estimated vesting of the related options. For purposes of preparing the
unaudited pro forma combined condensed financial statements, LSI Logic estimated
the intrinsic value of the unvested options using the average stock price used
for valuing the common stock. Upon completion of the merger, LSI Logic has
agreed to determine the final amount of deferred stock compensation based on the
closing price of its common stock on the date of completion of the merger, and,
therefore, the final amount of deferred stock compensation will be different
from the amounts presented in these unaudited pro forma combined condensed
financial statements.

     The purchase price for pro forma purposes has been allocated to tangible
assets acquired and liabilities assumed based on the fair value of C-Cube's
assets and liabilities. LSI Logic's management has

                                 (IN THOUSANDS)

engaged an independent appraiser to value the intangible assets, including
amounts allocable to C-Cube's in-process research and development. The
in-process research and development will be expensed immediately. For the
purposes of the unaudited pro forma combined condensed balance sheet, the
acquired in-process research and development has been assigned a value of $67
million based on management estimates. The in-process research and development
charge of $67 million is not reflected in the unaudited pro forma combined
condensed statement of operations. The exact amount of the in-process research
and development charge will be determined upon completion of the independent
appraisal and may be different from the amount presented in these unaudited pro
forma combined condensed financial statements. The in-process research and
development charge relates to C-Cube's products in development for which
technological feasibility has not been established.

     The allocation of purchase price is estimated as follows (in thousands):


                                                         
Tangible net assets acquired..............................  $136,696
Intangible assets, including goodwill.....................   646,749
Acquired in-process research and development..............    67,129
Deferred stock compensation...............................    46,287
                                                            --------
  Total purchase price....................................  $896,861
                                                            ========


     The unaudited pro forma combined condensed balance sheet reflects the
acquisition of C-Cube as of December 31, 2000. The unaudited pro forma combined
condensed statement of operations reflects the acquisition of C-Cube as if such
acquisition had occurred at the beginning of the period presented.

NOTE 2. UNAUDITED PRO FORMA COMBINED CONDENSED BALANCE SHEET

     The following adjustments were applied to the historical balance sheets of
LSI Logic and C-Cube at December 31, 2000 to arrive at the unaudited pro forma
combined condensed balance sheet:

          (a) To record estimated value of intangible assets, including
     goodwill.

          (b) To record the estimated transaction costs of $14.1 million.
     Estimated transaction costs include all costs directly attributable to the
     transaction including, but not limited to, fees for the financial advisors,
     accountants and attorneys and other related costs.

          (c) To record the increase in stockholders' equity of LSI Logic of
     $883 million as a result of the issuance of common shares and fair value of
     the LSI Logic options and warrants issued in exchange for outstanding
     shares, options and warrants of C-Cube and to eliminate C-Cube's historical
     common stock as a result of the purchase transaction.

          (d) To reflect the estimated one-time charge for acquired in-process
     research and development of approximately $67 million and to eliminate the
     historical retained earnings of C-Cube as a result of the purchase
     transaction.

          (e) To eliminate C-Cube's historical accumulated other comprehensive
     income.

NOTE 3. UNAUDITED PRO FORMA COMBINED CONDENSED STATEMENT OF OPERATIONS

     The following adjustments were applied to the historical audited statements
of operations for LSI Logic and C-Cube for the year ended December 31, 2000 to
arrive at the unaudited pro forma combined condensed statement of operations as
though the acquisition took place on January 1, 2000.

NOTE 4. UNAUDITED PRO FORMA COMBINED INCOME PER SHARE FROM CONTINUING OPERATIONS

     The following adjustments were applied to the historical audited statements
of operations for LSI Logic and C-Cube for the year ended December 31, 2000 to
arrive at the unaudited pro forma combined income per share as though the
acquisition took place on January 1, 2000.

          (c) Adjustment to reflect the estimated number of LSI Logic common
     shares to be issued in exchange for C-Cube common shares.

          (d) Adjustment to reflect the estimated number of shares to be issued
     in exchange for C-Cube common shares of 39.6 million plus common
     equivalents from C-Cube options assumed of 6.0 million and warrants assumed
     of 0.8 million less common equivalent shares of 22.0 million and interest
     expense of $11 million, net of taxes associated with the 1999 LSI Logic
     Convertible Notes excluded from the calculation because of their
     anti-dilutive effect only on the unaudited pro forma combined condensed
     diluted earnings per share.

                     DESCRIPTION OF LSI LOGIC CAPITAL STOCK

     The following description of the terms of the capital stock of LSI Logic is
not complete and is qualified by reference to the description of LSI Logic's
common stock contained in its registration statement on Form 8-A dated August
29, 1989, including any amendments or reports filed for the purpose of updating
such description, and the description of LSI Logic's Amended and Restated
Preferred Shares Rights Agreement in its Registration Statement on Form
8-A-12G/A dated December 8, 1998, which are incorporated in this prospectus by
reference. See "Where You Can Find More Information" on page 102.

AUTHORIZED CAPITAL STOCK

     Under the LSI Logic restated certificate of incorporation, LSI Logic's
authorized capital stock consists of (i) 1,300,000,000 shares of common stock,
par value $0.01 per share, and (ii) 2,000,000 shares of preferred stock, par
value $0.01 per share. As of April 10, 2001, there were 322,781,424 shares of
common stock issued and outstanding and there were no shares of preferred stock
issued and outstanding.

     LSI Logic's board of directors is authorized to provide for the issuance
from time to time of LSI Logic preferred stock in a series and, as to each
series, to fix the designation, powers, preferences and rights of the shares of
the series and the qualifications, limitations or restrictions on the series,
including:

     - the number of shares constituting the series and the distinctive
       designation of the series;

     - the dividend rate, whether dividends will be cumulative and the priority
       of the payment of dividends on shares of that series;

     - whether the series will have voting rights, and the terms of the voting
       rights;

     - whether the series will have conversion privileges, and the conversion
       terms and conditions;

     - whether the series will be redeemable and the redemption terms;

     - whether the series will have a sinking fund for the redemption or
       purchase of shares;

     - the rights of the series in the event of liquidation, dissolution or
       winding up of LSI Logic; and

     - any other relative or participating rights, preferences and limitations
       of the series.

     If LSI Logic's board of directors provides for the issuance of shares of
LSI Logic preferred stock and determines that the preferred stock is to have
some or all of the features listed above, there may be an adverse effect on the
availability of earnings for distribution to the holders of LSI Logic common
stock or for other corporate purposes.

STOCKHOLDER RIGHTS PLAN

     For a description of the rights to acquire LSI Logic preferred stock that
are attached to shares of LSI Logic common stock, see the section entitled
"Comparison of Rights of LSI Logic Stockholders and C-Cube
Stockholders -- Stockholder Rights Plan."

TRANSFER AGENT AND REGISTRAR

     EquiServe Trust Company, N.A. is the transfer agent and registrar for LSI
Logic common stock.

     COMPARISON OF RIGHTS OF LSI LOGIC STOCKHOLDERS AND C-CUBE STOCKHOLDERS

     Upon completion of the transaction, stockholders of C-Cube will become
stockholders of LSI Logic. As LSI Logic stockholders, the rights of former
C-Cube stockholders will be governed by the LSI Logic restated certificate of
incorporation and bylaws, which differ in certain material respects from
C-Cube's certificate of incorporation and bylaws. Both LSI Logic and C-Cube are
incorporated in the state of Delaware; therefore, the rights of former C-Cube
stockholders will continue to be governed by the Delaware General Corporation
Law.
                                        98
   104

     Described below is a summary comparison of material differences between the
rights of an LSI Logic stockholder under the current LSI Logic restated
certificate of incorporation and bylaws and the rights of a C-Cube stockholder
under the current C-Cube certificate of incorporation and bylaws. Copies of
these documents will be sent to holders of shares of C-Cube common stock upon
request. A summary by its nature is not complete. LSI Logic encourages you to
refer to the relevant portions of the LSI Logic restated certificate of
incorporation and bylaws, the C-Cube certificate of incorporation and bylaws and
the relevant provisions of Delaware law.

PERCENTAGE OF VOTING STOCK; INFLUENCE OVER AFFAIRS

     Upon completion of the transaction, the percentage ownership of LSI Logic
by each former C-Cube stockholder will be substantially less than each
stockholder's current percentage ownership of C-Cube. Accordingly, former C-Cube
stockholders will have a significantly smaller voting influence over the affairs
of LSI Logic than they currently enjoy over the affairs of C-Cube.

AMENDMENT TO THE CERTIFICATE OF INCORPORATION

     The Delaware General Corporation Law provides that, unless a greater vote
is required by the certificate of incorporation, amendment, adoption or repeal
of provisions of the certificate of incorporation requires the board of
directors to adopt a resolution setting forth the amendment, adoption or repeal,
and then present it to the stockholders to be voted upon. The amendment,
adoption or repeal of the certificate of incorporation must then be approved by
a majority of the outstanding stock entitled to vote, and a majority of the
outstanding stock of each class entitled to vote. The stockholders of the
outstanding shares of a class shall be entitled to vote as a class upon proposed
amendments, as described in Section 242 of the Delaware General Corporation Law.

     LSI LOGIC. The LSI Logic restated certificate of incorporation may be
amended, altered, changed or repealed in accordance with the Delaware General
Corporation Law.

     C-CUBE. The C-Cube Certificate of Incorporation may generally be amended,
altered, changed or repealed in accordance with the Delaware General Corporation
Law. However, the affirmative vote of at least 80% of the outstanding voting
power of all shares of C-Cube entitled to vote at an election of directors,
voting together as a single class, is required to alter, amend, adopt any
provision inconsistent with or repeal the provisions of the C-Cube certificate
of incorporation relating to the ability of the stockholders to act by written
consent, the authorization required to call a special meeting, or the size and
composition of C-Cube's board of directors.

AMENDMENT TO THE BYLAWS

     The Delaware General Corporation Law states that stockholders entitled to
vote have the power to adopt, amend or repeal the bylaws of a corporation. A
corporation, in its certificate, may also confer this power on the board of
directors in addition to the stockholders.

     LSI LOGIC. The LSI Logic bylaws may be adopted, amended or repealed by the
board of directors or the stockholders entitled to vote.

     C-CUBE. The C-Cube bylaws may be adopted, amended or repealed by the board
of directors or the stockholders entitled to vote, except that any proposed
alteration or repeal of, or the adoption of any bylaw inconsistent with any
provision of the bylaws relating to stockholders' annual and special meetings
(including notice provisions), action by written consent of stockholders and
directors (including the number, election, term and removal) shall require the
affirmative vote of at least 80% of the voting power of all voting stock then
outstanding, voting together as a single class.

CLASSIFICATION OF DIRECTORS

     Under the Delaware General Corporation Law, corporations may elect to have
a classified board, whereby only a portion of a corporation's directors are
elected at each annual meeting.
                                        99
   105

     LSI LOGIC. LSI Logic's board of directors currently consists of seven
members. Each member of the board of directors stands for election at each
meeting.

     C-CUBE. C-Cube's board of directors currently consists of five members.
C-Cube's bylaws provide that the board of directors shall be classified into
three classes, as nearly equal in size as possible. One class of directors
stands for election at each annual meeting of the stockholders.

NOMINATION OF DIRECTORS

     LSI LOGIC. A stockholder must make any nomination for a director in writing
to the secretary of LSI Logic between 60 and 90 days prior to the annual meeting
of the stockholders. In the event that less than 65 days' notice of the meeting
is given to stockholders, any nomination must be delivered not later than the
close of business on the seventh day following the day on which the notice of
the meeting was mailed.

     C-CUBE. A stockholder must make any nomination for a director in writing to
the secretary of C-Cube not less than 120 days in advance of the anniversary of
the preceding year's annual meeting. In the event that no annual meeting was
held in the previous year or the date of the annual meeting has been changed by
more than 30 days from the date of the previous year's annual meeting, any
nomination for a director must be made not earlier than the later of 120 days in
advance of the annual meeting or 10 days following the day on which public
announcement of the date of the annual meeting is first made.

STOCKHOLDER PROPOSALS

     LSI LOGIC. A stockholder may bring business before the a meeting of
stockholders, provided that the stockholder delivers notice in writing to the
secretary of LSI Logic between 60 and 90 days prior to the meeting. In the event
that the less than 65 days' notice of the meeting is given to stockholders, any
notice must be delivered not later than the close of business on the seventh day
following the day on which the notice of the meeting was mailed.

     C-CUBE. A stockholder may bring business before the annual meeting of
stockholders, provided that the stockholder delivers notice in writing to the
secretary of C-Cube not less than 120 days in advance of the first anniversary
of the preceding year's annual meeting. In the event that no annual meeting was
held in the previous year or the date of the annual meeting has been changed by
more than 30 days from the date of the previous year's annual meeting, any
notice must be made not earlier than the later of 120 days in advance of the
annual meeting or ten days following the day on which public announcement of the
date of the annual meeting is first made.

SPECIAL MEETING OF STOCKHOLDERS

     The Delaware General Corporation Law states that a special meeting of
stockholders may be called by the board of directors or by such person or
persons as may be authorized by the certificate of incorporation or the bylaws.

     LSI LOGIC. The LSI Logic bylaws provide that a special meeting of
stockholders may be called at any time only by the board of directors, by the
chairman of the board of directors, by the president or by the chief executive
officer.

     C-CUBE. The C-Cube certificate of incorporation provides that a special
meeting of stockholders may only be called by the board of directors or by the
chairman of the board of directors, and no business other than that in the
notice of the special meeting may be transacted at any special meeting.

CUMULATIVE VOTING

     The Delaware General Corporation Law provides that the certificate of
incorporation of any corporation may provide for cumulative voting.

     LSI LOGIC. The LSI Logic restated certificate of incorporation states that
stockholders may cumulatively vote their shares, and are therefore entitled to
the number of votes equal to the number of
                                       100
   106

votes which the stockholder would be entitled to cast for the election of
directors with respect to the stockholder's shares of stock multiplied by the
number of directors to be elected, and the stockholder may cast all of such
votes for a single candidate or distribute them among the number of directors to
be elected, or for any two or more of them as the stockholder sees fit.

     C-CUBE. The C-Cube certificate of incorporation does not provide for
cumulative voting.

ACTION BY WRITTEN CONSENT

     Under the Delaware General Corporation Law, unless otherwise provided in
the certificate of incorporation, any action required to be taken at an annual
or special meeting of the stockholders may be taken without a meeting, without
prior notice and without a vote, by an action by written consent of the
stockholders otherwise entitled to vote.

     LSI LOGIC. The LSI Logic bylaws state that the stockholders may act by
written consent on any matter which would otherwise be voted on in an annual or
special meeting of the stockholders.

     C-CUBE. The C-Cube certificate of incorporation states that any action
required or permitted to be taken by the stockholders must be effected at a duly
called annual or special meeting of the stockholders and may not be effected by
an action by written consent.

STOCKHOLDER RIGHTS PLAN

     LSI LOGIC. On December 15, 1988, LSI Logic's board of directors declared a
dividend of one preferred stock purchase right for each outstanding share of LSI
Logic common stock to the stockholders of record on that date. The preferred
stock purchase rights are governed by the Amended and Restated Preferred Shares
Rights Agreement, dated as of November 20, 1998, between LSI Logic and
BankBoston, N.A.

     Under the terms of the stockholders rights plan, the preferred stock
purchase rights will become exercisable upon the occurrence of certain
"triggering events," including the acquisition by an acquiring person of 20% of
the outstanding shares of LSI Logic common stock. The preferred stock purchase
rights also entitle the stockholders to acquire stock of the "acquiring person"
under certain circumstances. The existence of the stockholder rights plan may
discourage or render more difficult an acquisition of LSI Logic that is deemed
undesirable by LSI Logic's board of directors.

     C-CUBE. C-Cube does not have a stockholder rights plan.

                                 LEGAL MATTERS

     Cooley Godward LLP will pass on the validity of the shares of LSI Logic
common stock to be issued to C-Cube stockholders in the transaction. Certain tax
consequences of the transaction will be passed upon for LSI Logic by Cooley
Godward LLP and for C-Cube by Wilson Sonsini Goodrich & Rosati, Professional
Corporation.

     Wilson Sonsini Goodrich & Rosati, Professional Corporation, incorporated
LSI Logic in 1980 and has acted as their outside legal counsel since that time.
Larry W. Sonsini has been a member of LSI Logic's board of directors since 2000.
In addition, Mr. Sonsini has been a member of the law firm of Wilson Sonsini
Goodrich & Rosati since 1969, where he currently serves as the Chairman of the
Board and Chief Executive Officer. Wilson Sonsini Goodrich & Rosati has also
represented C-Cube in general corporate matters and in various transactions
since its initial public offering in 1994. Because of Mr. Sonsini's personal
involvement in the recent transaction between Harmonic Inc. and C-Cube, among
other things, Mr. Sonsini and Mr. Corrigan believed it to be in the best
interests of all parties involved for Wilson Sonsini Goodrich & Rosati to act as
outside legal counsel to C-Cube for this transaction and for LSI Logic to seek
separate outside legal counsel. Recognizing the potential conflicts of interest
posed, both C-Cube and LSI Logic executed appropriate conflict waivers. In
addition, since the date of engagement as outside legal counsel by C-Cube in
this transaction, Mr. Sonsini has not participated as a member of LSI
                                       101
   107

Logic's board of directors, or otherwise on behalf of LSI Logic, in any
discussion, negotiation or vote regarding the exchange offer or the merger.

                          INDEPENDENT AUDITORS' REPORT

To the Board of Directors and Stockholders of
C-Cube Microsystems Inc.:

     We have audited the accompanying consolidated balance sheets of C-Cube
Microsystems Inc. and subsidiaries as of December 31, 2000 and 1999, and the
related consolidated statements of operations, changes in stockholders' equity
and cash flows for each of the three years in the period ended December 31,
2000. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

     We conducted our audits in accordance with auditing standards generally
accepted in the United States of America. Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

     In our opinion, such consolidated financial statements present fairly, in
all material respects, the financial position of C-Cube Microsystems Inc. at
December 31, 2000 and 1999, and the results of their operations and their cash
flows for each of the three years in the period ended December 31, 2000 in
conformity with accounting principles generally accepted in the United States of
America.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                  YEARS ENDED DECEMBER 31, 2000, 1999 AND 1998

NOTE 1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

ORGANIZATION

     C-Cube Microsystems Inc. (the "Company" or "C-Cube") was founded in July
1988. The Company operates as a leading provider of both digital video
semiconductor solutions that implement international standards for digital
video, including MPEG-1 and MPEG-2.

     C-Cube entered into an Amended and Restated Agreement and Plan of Merger
and Reorganization with Harmonic Inc. on December 9, 1999. In accordance with
this agreement, on May 2, 2000, C-Cube's semiconductor division was spun-off
into an independent company, C-Cube Semiconductor Inc., and on May 3, 2000,
C-Cube Microsystems Inc., consisting primarily of its DiviCom division, was
merged with Harmonic Inc. C-Cube Semiconductor Inc. was then renamed C-Cube
Microsystems Inc. (the "Company" or "C-Cube") with the approval of Harmonic,
Inc., to maintain customer continuity and the brand identity of C-Cube's
semiconductor products. The transaction was accounted for as if the
semiconductor division were the continuing entity. Accordingly, as required by
Accounting Principles Board Opinion No. 30 and Emerging Issues Task Force Issue
No. 95-18, the results of operations of the Semiconductor division (the
continuing entity) are reported separately from the results of operations of the
DiviCom division (the discontinued entity). The results of operations in prior
periods have been restated and certain prior period amounts have been
reclassified to conform to the current period presentation. These restatements
and reclassifications had no effect on net income or stockholders' equity.

CONSOLIDATION

     The consolidated financial statements include the Company, its wholly owned
subsidiaries and C-Cube Japan, Inc. (a 65% owned Japanese subsidiary) after
elimination of intercompany accounts and transactions.

CASH AND EQUIVALENTS AND SHORT-TERM INVESTMENTS

     All highly liquid debt instruments purchased with an original maturity of
three months or less are classified as cash equivalents.

     Management determines the classification of debt and equity securities at
the time of purchase and reevaluates the classification at each balance sheet
date. Short-term investments are classified as available-for-sale when the
Company generally has the ability and intent to hold such securities to
maturity, but, in certain circumstances, may potentially dispose of such
securities prior to their maturity to implement management strategies.
Securities available-for-sale are reported at fair value with unrealized gains
and losses reported as a separate component of stockholders' equity. All
available-for-sale securities are classified as current assets.

INVENTORIES

     Inventories are stated at the lower of cost (first-in, first-out) or
market. Cost is computed using standard costs which approximate actual cost on a
first-in, first-out basis.

PROPERTY AND EQUIPMENT

     Property and equipment are stated at cost. Depreciation is provided using
the straight-line method over estimated useful lives of three years. Equipment
under capital leases are amortized over the shorter of their estimated useful
lives or three years. Leasehold improvements are amortized over the lease term.

                  YEARS ENDED DECEMBER 31, 2000, 1999 AND 1998

REVENUE RECOGNITION AND ACCOUNTS RECEIVABLE

     The Company records product sales to customers and distributors at the time
of shipment. Certain of the Company's agreements with its distributors permit
limited stock rotation and provide for price protection. Allowances for returns
and adjustments, including price protection, are provided at the time sales are
recorded.

     In December 1999, the Securities and Exchange Commission issued Staff
Accounting Bulletin No. 101 ("SAB 101"), "Revenue Recognition," which provides
guidance on the recognition, presentation and disclosure of revenue in financial
statements filed with the Securities and Exchange Commission. SAB 101 outlines
the basic criteria that must be met to recognize revenue and provides guidance
for disclosures related to revenue recognition policies. SAB 101 is effective
for the fiscal quarter beginning October 1, 2000. The adoption of SAB 101 did
not have a material impact on the consolidated financial statements.

RESEARCH AND DEVELOPMENT

     Research and development expenses include costs and expenses associated
with the development of the Company's design methodology and the design and
development of new products, including initial nonrecurring engineering and
product verification charges from foundries. Research and development is
expensed as incurred.

INCOME TAXES

     The Company accounts for income taxes in accordance with Statement of
Financial Accounting Standards No. 109 "Accounting for Income Taxes," which
prescribes the use of the asset and liability approach whereby deferred tax
liabilities and assets are calculated for the expected future tax consequences
of temporary differences between the financial statement carrying amounts and
the tax bases of assets and liabilities, net operating loss and tax credit
carryforwards.

ESTIMATES

     The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect reported amounts of
assets, liabilities, revenues and expenses as of the dates and for the periods
presented. Actual results could differ from those estimates.

FAIR VALUE OF FINANCIAL INSTRUMENTS

     Financial instruments include cash equivalents, short-term investments and
a promissory note. Cash equivalents and short-term investments are stated at
fair value based on quoted market prices. The estimated fair value of all other
financial instruments at December 31, 2000 and 1999 was not materially different
from the values presented in the consolidated balance sheets.

CONCENTRATION OF CREDIT RISK

     Financial instruments which potentially subject the Company to
concentrations of credit risk consist primarily of cash equivalents, short-term
investments, accounts receivable and financial instruments used in hedging
transactions. By policy, the Company places its investments only with financial
institutions meeting its credit guidelines and, other than U.S. Government
Treasury instruments, limits the amounts invested in any one institution or in
any type of instrument. Almost all of the Company's accounts receivable are
derived from sales to manufacturers and distributors in the consumer electronics
industry.

                  YEARS ENDED DECEMBER 31, 2000, 1999 AND 1998

The Company performs ongoing credit evaluations of its customers' financial
condition and manages its exposure to losses from bad debts by limiting the
amount of credit extended whenever deemed necessary and generally does not
require collateral. At December 31, 2000, 33% and 17% of the Company's accounts
receivables were from two customers. No other customers accounted for more than
10% of accounts receivable. At December 31, 1999, three customers accounted for
greater than 10% of accounts receivable and were 18%, 12% and 12% of the
balance.

     The geographic distribution of receivables is as follows:

FOREIGN CURRENCY TRANSLATION

     The functional currency of C-Cube Japan is the Japanese yen. Accordingly
all assets and liabilities of C-Cube Japan are translated at the current
exchange rate at the end of the period and revenues and costs at average
exchange rates in effect during the period. Gains and losses from foreign
currency translation are recorded as a separate component of stockholders'
equity.

FORWARD EXCHANGE CONTRACTS

     In the normal course of business, the Company has exposure to foreign
currency fluctuations arising from foreign currency purchases and inter-company
sales, among other things. The Company enters into forward exchange contracts to
neutralize the impact of foreign currency fluctuations on assets and
liabilities. Gains and losses on forward exchange contracts and the related
receivables are recorded in other income. The costs of entering into such
contracts are not material to the Company's financial results. The fair value of
exchange contracts is determined by obtaining quoted market prices of comparable
contracts at the balance sheet date, adjusted by interpolation where necessary
for maturity differences. The Company's risk in these contracts is the cost of
replacing, at current market rates, these contracts in the event of default by
the other party. These contracts are executed with creditworthy financial
institutions and are denominated in the currency of major industrial nations.

     At December 31, 2000, the Company had $3.9 million of outstanding foreign
exchange contracts to sell Japanese yen. The estimated fair values of these
contracts at December 31, 2000 were not materially different from the net
carrying values. These contracts mature through January 2001. Unrealized gains
on forward exchange contracts at December 31, 2000 were not material.

     At December 31, 1999, the Company had $3.1 million of outstanding foreign
exchange contracts to sell Japanese yen, $1.5 million of outstanding foreign
exchange contracts to sell Great Britain pounds and $0.2 million of outstanding
foreign exchange contracts to sell French francs. The estimated fair values of
these contracts at December 31, 1999 were not materially different from the net
carrying values. These contracts matured through January 2000. Unrealized gains
on forward exchange contracts at December 31, 1999 were not material.

     In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standard No. 133 ("SFAS 133"), "Accounting for Derivative
Instruments and Hedging Activities," which

                  YEARS ENDED DECEMBER 31, 2000, 1999 AND 1998

establishes accounting and reporting standards for derivative instruments,
including certain derivative instruments embedded in other contracts, and for
hedging activities. It requires that an entity recognize all derivatives as
either assets or liabilities in the statement of financial position and measure
those instruments at fair value. SFAS 133 is effective for fiscal years
beginning after June 15, 2000. The Company adopted SFAS 133 on January 1, 2001.
The adoption of this statement did not have a material impact on the
consolidated financial statements.

INTANGIBLES

     The Company amortizes distribution rights over 15 years and other
intangible assets over 5 years. The Company reviews intangibles and other
long-lived assets for impairment whenever events or changes in circumstances
indicate that the carrying amount of an asset may not be recoverable.
Recoverability of intangibles and other long-lived assets is measured by
comparison of its carrying amount to future net cash flows the intangibles and
other long-lived assets are expected to generate. If such assets are considered
to be impaired, the impairment to be recognized is measured by the amount by
which the carrying amount of the intangible or other long-lived asset exceeds
its fair market value, as determined by discounted cash flows using a discount
rate reflecting the Company's average cost of funds.

EARNINGS PER SHARE

     Basic earnings per share ("EPS") excludes dilution and is computed by
dividing net income (loss) by the weighted average number of common shares
outstanding for the period. Diluted EPS reflects the potential dilution that
would occur if securities or other contracts to issue common stock were
exercised or converted into common stock.

STOCK-BASED COMPENSATION

     The Company accounts for stock-based awards to employees using the
intrinsic value method in accordance with Accounting Principles Board No. 25,
"Accounting for Stock Issued to Employees." In connection with the merger and
spin-off, the Company recorded stock-based compensation expense, within selling,
general and administrative, of $15.5 million related to the accelerated vesting
of options for certain employees of the Company.

RECLASSIFICATIONS

     Certain reclassifications have been made to prior year balances in order to
conform to the current year presentation.

NOTE 2. DISCONTINUED OPERATIONS

     The results of discontinued operations are presented on two line items on
the face of the Consolidated Statements of Income. For the current year, loss
from operations of DiviCom represents the net loss of DiviCom operations through
the date of merger of $10.1 million. Revenues and taxes for this period were
$36.8 million and $6.8 million, respectively. For the year ended December 31,
1999 revenues and taxes were $185.5 million and $10.2 million. Revenues and
taxes for the year ended December 31, 1998 were $142.7 million and $9.1 million
respectively. Loss on disposal of DiviCom of $6.2 million includes direct costs,
net of taxes, associated with the merger/spin-off transactions that were
incurred by the Company.

NOTE 6. PRODUCTION CAPACITY RIGHTS

     In the fourth quarter of 1999, the Company signed a production capacity
agreement with United Microelectronics Corporation (UMC) to provide chip
production capacity in the years 2000 to 2002, for which it paid a $20.0 million
refundable payment in January 2000, classified as non-current asset. This
deposit earns interest at 4% per year, allows for certain discounts on purchased
capacity based upon the quantities purchased and is refundable after 90 days
notice by the Company. The agreement does not commit the Company to purchase
chips, but does guarantee the availability of a set capacity of chips at "not to
exceed" prices.

     In the second quarter of 1996, the Company expanded and formalized its
relationship with Taiwan Semiconductor Manufacturing Co., Ltd. (TSMC) to provide
wafer production capacity in the years 1996 to 2001. The agreement with TSMC
provided that TSMC would produce and ship wafers to the Company at specified
prices and required the Company to make two advance payments totaling $49.0
million. An advance payment of $24.5 million was made in June 1996. In May 1997,
the Company amended its agreement with TSMC which resulted in a reduction of the
Company's future wafer purchase commitments and the forgiveness of the second
advance payment of $24.5 million. In January 1999, the Company signed a second
amendment to its agreement with TSMC which resulted in a refund to the Company
of $11.7 million and an extension of the term of the agreement to 2003. Advance
payments associated with wafer production capacity rights are amortized over the
shorter of the contract period or the actual delivery of wafers in relation to
the minimum number of wafers to be purchased under the agreement. At December
31, 2000, remaining production capacity rights were $5.7 million, of which $2.1
million was included in other current assets and $3.6 million was classified as
a non-current asset.

NOTE 7. LINE OF CREDIT

     As of December 31, 2000 the Company had a $27.0 million bank line of credit
($27.0 million outstanding at December 31, 2000) that expires on May 31, 2002.
The first $6.0 million of borrowed funds bear interest at LIBOR plus 2.0% (8.4%
at December 31, 2000), with additional borrowings bearing interest at the bank's
prime rate (9.5% at December 31, 2000). The line of credit agreement requires
that the Company, among other things, maintain a minimum tangible net worth and
certain financial ratios and is collateralized by the current assets of the

     In November 1995, the Company completed a public debt offering of $86.3
million of convertible subordinated notes (the "notes") that matured in 2005.
Interest was payable semi-annually at 5.875% per annum. The notes became
convertible at the option of the note holders into the Company's common stock at
an initial conversion price of $30.70 per share, subject to adjustment.
Beginning in November 1997, the notes became redeemable at the option of the
Company at an initial redemption price of 104.7% of the principal amount.

     During 2000 all note holders elected the option to convert their notes into
shares of the Company's common stock at a price of $30.70. The price was
equivalent to 103.5% of the principal amount. The loss on conversion of the
notes was not material to the Company.

     During 1999, the Company repurchased $3.4 million of the notes at 95.5% of
the principal amount, with accrued interest to the date of repurchase.

     During 1998, the Company repurchased $63.5 million of the face value of the
notes at 88.4% of the principal amount, with accrued interest to the date of
repurchase, and recognized an extraordinary gain of $3.5 million, or $0.09 per
diluted share, net of related income taxes of $2.4 million.

NOTE 9. COMMITMENTS AND CONTINGENCIES

     Equipment with a cost of $6.2 million and $5.0 million and accumulated
depreciation of $2.8 million and $0.8 million was leased under capital leases at

     Rent expense for operating leases was approximately $3.6 million, $3.0
million and $2.3 million for the years ended December 31, 2000, 1999 and 1998,
respectively.

     The Company has been named as a defendant in a securities class-action
complaint filed in the United States district court for the northern district of
California. The plaintiffs in this action purport to represent the class of all
persons who purchased common stock between January 19th, 2000 and May 3, 2000 in
the entity then known as C-Cube Microsystems (see Note 1). The complaint alleges
that the Company is liable for the acts and statements for the entity known as
C-Cube Microsystems prior to May 3, 2000 even though the Company did not legally
exist prior to May 3, 2000. This case is in its early stages and the Company
believes that the allegations contained in the complaint are without merit and
intends to defend the action vigorously.

     From time-to-time the Company is party to certain litigation or legal
claims. Management has reviewed all pending legal matters and believes that the
resolution of such matters will not have a significant adverse effect on the
Company's financial position or results of operations.

  Warrant issuance

     On February 10, 2000, C-Cube entered into a Securities Purchase Agreement
("Agreement") with Thomson Multimedia S.A., a French societe anonyme, whereby,
on May 8, 2000, C-Cube issued and sold to Thomson 474,747 shares of non-voting
common stock at a price of $19.78 per share and issued to Thomson a warrant to
purchase 949,494 shares of common stock. The warrants were fully vested upon
issuance and will become exercisable at a price of $19.78 per share one week
prior to the expiration date of May 8, 2007, or in part prior to the expiration
date upon the achievement of certain milestones. The Company calculated the fair
value of the warrants using the Black-Scholes options pricing model with the
following weighted-average assumptions: expected life, 7 years; stock
volatility, 69%; risk-free interest rate, 6.82%, and no dividends during the
expected term. The Company recorded a charge, within research and development,
of $12.6 million in the second quarter of 2000.

  Employee Stock Option Plans

     The Company's stock option plans (the "Plans") authorize the issuance of
25,000,000 shares of common stock (included in the 25,450,000 authorized shares
discussed above) for the grant of incentive or nonstatutory stock options and
the direct award or sale of shares to employees, directors, contractors and
consultants. Under the Plans, options are generally granted at fair value at the
date of grant. Such options become exercisable over periods of one to five years
and expire up to 10 years from the grant date.

     Option activity under the Plans was as follows:

     C-Cube's 2000 Stock Option Plans include Employee Stock Option Plan and
Director Option Plan. The Employee Stock Option Plan has an annual increase on
January 1, 2001, equal to 3% of shares outstanding.

  Employee Stock Purchase Plan

     The Company has an employee stock purchase plan, under which eligible
employees may authorize payroll deductions of up to 10% of their compensation
(as defined in the plan) to purchase common stock at a price equal to 85% of the
lower of the fair market values as of the beginning of the offering period or
end of the purchase period. Stock issued under the plan was 316,000, 328,000 and
223,000 shares in 2000, 1999 and 1998 at weighted average prices of $17.77,
$17.16 and $15.52, respectively. The weighted average fair market value of the
2000, 1999 and 1998 awards was $24.02, $7.96 and $7.06, respectively. At
December 31, 2000, 1,039,635 shares of common stock were available for issuance
under this plan.

  Additional Stock Plan Information

     As discussed in Note 1, the Company continues to account for its
stock-based awards using the intrinsic value method in accordance with
Accounting Principles Board No. 25, "Accounting for Stock Issued to Employees"
and its related interpretations. Accordingly, no compensation expense has been
recognized in the financial statements for employee stock arrangements which are
granted with exercise prices equal to the fair market value at grant date.

     Statement of Financial Accounting Standards No. 123, "Accounting for
Stock-Based Compensation," (SFAS 123) requires the disclosure of pro forma net
income and earnings per share had the Company adopted the fair value method as
of the beginning of fiscal 1995. Under SFAS 123, the fair value of stock-based
awards to employees is calculated through the use of option pricing models, even
though such models were developed to estimate the fair value of freely tradable,
fully transferable options without vesting restrictions, which significantly
differ from the Company's stock option awards. These models also require
subjective assumptions, including future stock price volatility and expected
time to exercise, which greatly affect the calculated values. The Company's
calculations were made using the Black-Scholes option pricing model with the
following weighted average assumptions: expected life, 5.8 in 2000, 5.8 in 1999
and 5.6 in 1998; stock volatility, 49% in 2000, 68% in 1999 and 68% in 1998;
risk free interest rates, 5.2% in 2000, 5.5% in 1999 and 5.2% in 1998; and no
dividends during the expected term. The Company's

calculations are based on a single option valuation approach and forfeitures are
recognized as they occur. If the computed fair values of the 2000, 1999 and 1998
awards had been amortized to expense over the vesting period of the awards, pro
forma net income (loss) would have been $(56.0) million ($(1.04) per share),
$25.7 million ($0.66 per share) in 1999 and $15.2 million ($0.52 per share) in
1998. Per share amounts above represent diluted earnings per share under SFAS
128 (see Note 1).

  Employee Benefit Plan

     The Company has a 401(k) tax-deferred savings plan under which participants
may contribute up to 20% of their compensation, subject to certain Internal
Revenue Service limitations. The Company is not required to contribute and has
not contributed to the plan to date.

     The tax benefit associated with dispositions from employee stock plans
reduced taxes currently payable by $86.2 million, $28.9 million and $1.4 million
for 2000, 1999 and 1998, respectively.

     The Company incurred a tax liability of $431.4 million as a result of
separating DiviCom from C-Cube. DiviCom was subsequently merged into Harmonic,
Inc. The liability reduced stockholders' equity.

     At December 31, 2000, the Company has tax credit carryforwards of
approximately $14 million expiring through 2007.

     U.S. income taxes were not provided on a cumulative total of approximately
$6 million and $20 million of undistributed earnings from foreign subsidiaries
for the years ending December 31, 2000 and 1999, respectively. The Company
intends to reinvest these earnings indefinitely in foreign operations. It is not
practicable to estimate the income tax liability that might be incurred upon the
remittance of such earnings.

NOTE 14. EXTRAORDINARY ITEM

     During 1998, the Company repurchased $63.5 million of the face value of the
Company's 5.875% subordinated convertible notes due 2005 (the "notes") at 88.4%
of the principal amount, with accrued interest to the date of repurchase, and
recognized an extraordinary gain of $3.5 million, or $0.09 per diluted share,
net of related income taxes of $2.4 million.

NOTE 18. SUBSEQUENT EVENTS

     On March 26, 2001 the Company entered into an Agreement and Plan of
Reorganization (the "Reorganization Agreement") with LSI Logic Corporation
("LSI") and Clover Acquisition Corp. ("Merger Sub"), a wholly-owned subsidiary
of LSI. Under the terms of the Reorganization Agreement, Merger Sub will
commence an exchange offer (the "Offer") to exchange 0.79 shares of common
stock, par value $0.01 per share, of LSI (the "LSI Common Stock"), for each
outstanding share of C-Cube common stock, par value $0.001 per share. Holders of
C-Cube common stock tendering their shares in the Offer will receive cash in
lieu of any fractional shares of LSI Common Stock to which they would otherwise
be entitled. The consummation of the Offer is subject to, among other things, at
least a majority of shares of our common stock (including for purposes of the
calculation of the majority of shares, certain outstanding options and warrants
to purchase C-Cube shares) being validly tendered and not withdrawn prior to the
expiration of the Offer and the expiration or termination of the waiting periods
under the Hart-Scott-Rodino Antitrust Improvements Act and applicable foreign
antitrust laws. Pursuant to the Reorganization Agreement, following the
completion of the Offer and the satisfaction or waiver of certain other
conditions, Merger Sub will be merged into us (the "Merger") and C-Cube will be
the surviving corporation. In the Merger, each outstanding share of C-Cube
common stock (other than shares held by C-Cube as treasury stock, by LSI or
Merger Sub and by stockholders who perfect appraisal rights under Delaware law,
which will be available if Merger Sub owns ninety percent (90%) or more of the
outstanding shares of C-Cube common stock following the consummation of the
Offer) will be converted into the right to receive the same consideration as
paid to C-Cube stockholders who tendered their common stock in the Offer. In the
event that a third party makes a proposal to acquire C-Cube or if the no
solicitation provisions contained in the Reorganization Agreement are materially
breached, and thereafter the Reorganization Agreement is terminated, under
certain circumstances C-Cube will be required to pay a $33 million termination
fee to LSI. The closing is anticipated to take place during the second quarter
of 2001. Based on the closing price of LSI common stock on March 23, 2001, the
last trading day prior to the announcement of the transaction, the transaction
was valued at approximately $878 million. The transaction is expected to be
accounted for under the purchase method of accounting and to qualify as a
"tax-free" reorganization for federal income tax purposes.

  A  FORM OF STOCKHOLDER AGREEMENT

ANNEX

  I  CONDITIONS TO THE OFFER

                                      -iii-
   142

     AGREEMENT AND PLAN OF REORGANIZATION, dated as of March 26, 2001 (this
"AGREEMENT"), by and among C-Cube Microsystems Inc., a Delaware corporation (the
"COMPANY"), LSI Logic Corporation, a Delaware corporation ("PARENT"), and Clover
Acquisition Corp., a Delaware corporation and a wholly owned subsidiary of
Parent ("MERGER SUB").

                                   WITNESSETH

     WHEREAS, the respective Boards of Directors of Parent, Merger Sub and the
Company have approved this Agreement, and declared advisable that Merger Sub
make an exchange offer (the "Offer") to exchange shares of common stock, par
value $0.01 per share, of Parent ("Parent Shares" or "Parent Common Stock"), for
shares of common stock, par value $0.001 per share, of the Company ("Company
Common Stock") and have approved the merger of Merger Sub with and into the
Company (the "Merger") upon the terms and subject to the conditions of this
Agreement and in accordance with the General Corporation Law of the State of
Delaware ("DGCL");

     WHEREAS, concurrently with the execution of this Agreement, and as a
condition and inducement to Parent's willingness to enter into this Agreement,
certain stockholders of the Company are entering into Stockholder Agreements in
substantially the form attached hereto as Exhibit A (the "Stockholder
Agreements"); and

     WHEREAS, it is intended that, for United States federal income tax
purposes, the Offer and the Merger (together, the "Transaction") shall be
treated as an integrated transaction and shall qualify as a "reorganization"
within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as
amended (the "Code").

     NOW, THEREFORE, in consideration of the representations, warranties,
covenants, agreements and conditions set forth herein, and intending to be
legally bound hereby, the parties hereto agree as follows:

                                   ARTICLE I

                            THE OFFER AND THE MERGER

     SECTION 1.1  The Offer.

     (a) Provided that this Agreement shall not have been terminated in
accordance with Section 7.1 hereof, Merger Sub shall, as promptly as practicable
after the date hereof (and Merger Sub shall use commercially reasonable efforts
to, within ten (10) business days after the date hereof), commence the Offer.
Each Share accepted by Merger Sub pursuant to the Offer shall be exchanged for
the right to receive a fraction of share of Parent Common Stock (the "Exchange
Ratio") equal to 0.79. The initial expiration date of the Offer shall be the
twentieth business day following commencement of the Offer. The Offer shall be
subject to the condition that there shall be validly tendered in accordance with
the terms of the Offer prior to the expiration date of the Offer (as it may be
extended in accordance with the requirements of this Section 1.1(a)) and not
withdrawn a number of shares of Company Common Stock which, together with the
shares of Company Common Stock then owned by Parent and Merger Sub (if any),
represents at least a majority of the sum of (i) the total number of shares of
Company Common Stock outstanding immediately prior to the expiration of the
Offer (as it may be extended in accordance with the requirements of this Section
1.1(a)), and (ii) a number of shares of Company Common Stock determined by
Parent up to a maximum of the total number of shares of Company Common Stock
issuable upon the exercise or conversion of all options, warrants, rights and
convertible securities (if any) that will be vested by the Outside Date (as
defined in Section 7.1(b)(ii) hereof) (the number of shares determined by adding
the shares referred to in clause "(i)" and clause "(ii)" of this sentence being
hereinafter referred to as the "Fully Diluted Shares") (and the condition
previously referred to in this sentence being referred to as the "Minimum
Condition") and to the other conditions set forth in Annex I hereto. Parent and
Merger Sub expressly reserve the right to waive the conditions to the Offer and
to make any change in the terms or conditions of the Offer; provided, however,
that without the prior written

                                       A-1
   143

consent of the Company, no change may be made which decreases the number of
shares of Company Common Stock sought in the Offer, changes the form or amount
of consideration to be paid, imposes conditions to the Offer in addition to
those set forth in Annex I, changes or waives the Minimum Condition or any of
the conditions set forth in clauses (2), (4), (5) or (7) of Annex I, extends the
Offer (except as set forth in the following two sentences), or makes any other
change to any of the terms and conditions to the Offer which is adverse to the
holders of shares of Company Common Stock. Subject to the terms of the Offer and
this Agreement and the satisfaction (or waiver to the extent permitted by this
Agreement) of the conditions to the Offer, Merger Sub shall accept for payment
all shares of Company Common Stock validly tendered and not withdrawn pursuant
to the Offer as soon as practicable after the applicable expiration date of the
Offer (as it may be extended in accordance with the requirements of this Section
1.1(a)) and shall pay for all such shares of Company Common Stock promptly after
acceptance; provided, however, that (x) Merger Sub shall extend the Offer for
successive extension periods not in excess of ten (10) business days per
extension if, at the scheduled expiration date of the Offer or any extension
thereof, any of the conditions to the Offer shall not have been satisfied or
waived, until such time as such conditions are satisfied or waived, and (y)
Merger Sub may extend the Offer if and to the extent required by the applicable
rules and regulations of the Securities and Exchange Commission ("SEC") or The
New York Stock Exchange (the "NYSE"). In addition, Merger Sub may extend the
Offer after the acceptance of shares of Company Common Stock thereunder for a
further period of time by means of a subsequent offering period under Rule
14d-11 promulgated under the Securities Exchange Act of 1934, as amended (the
"Exchange Act"). No fraction of a share of Parent Common Stock will be issued in
connection with the exchange of Parent Common Stock for shares of Company Common
Stock upon consummation of the Offer, but in lieu thereof each tendering
stockholder who would otherwise be entitled to receive a fraction of a share of
Parent Common Stock (after aggregating all fractional shares of Parent Common
Stock that otherwise would be received by such stockholder) in the Offer shall
receive from Parent an amount of cash (rounded up to the nearest whole cent),
without interest, equal to the product obtained by multiplying such fraction by
the average closing sale price of one (1) share of Parent Common Stock on the
NYSE during the ten (10) trading days ending on the trading day immediately
prior to the expiration of the Offer (as it may be extended in accordance with
the requirements of this Section 1.1(a)).

     (b) As soon as practicable after the date of this Agreement, Parent shall
prepare and file with the SEC a registration statement on Form S-4 to register
the offer and sale of Parent Common Stock pursuant to the Offer (the
"Registration Statement"). The Registration Statement will include a preliminary
prospectus containing the information required under Rule 14d-4(b) promulgated
under the Exchange Act (the "Preliminary Prospectus"). As soon as practicable on
the date of commencement of the Offer, Parent and Merger Sub shall (i) file with
the SEC a Tender Offer Statement on Schedule TO with respect to the Offer which
will contain or incorporate by reference all or part of the Preliminary
Prospectus and form of the related letter of transmittal and summary
advertisement, if any (together with any supplements or amendments thereto,
collectively the "Offer Documents"), and (ii) cause the Offer Documents to be
disseminated to holders of shares of Company Common Stock. The Company shall
promptly furnish to Parent and Merger Sub all information concerning the
Company, the Company's Subsidiaries and the Company's stockholders that may be
required or reasonably requested in connection with any action contemplated by
this Section 1.1(b). Parent, Merger Sub and the Company each agree promptly to
correct any information provided by it for use in the Registration Statement or
the Offer Documents if and to the extent that such information shall have become
false or misleading in any material respect. Parent and Merger Sub agree to take
all steps necessary to cause the Offer Documents as so corrected to be filed
with the SEC and to be disseminated to holders of shares of Company Common Stock
, in each case as and to the extent required by applicable federal securities
laws. The Company and its counsel shall be given a reasonable opportunity to
review and comment on the Schedule TO, the Registration Statement and the Offer
Documents prior to their being filed with the SEC. Parent agrees to provide the
Company and its counsel with any comments Parent, Merger Sub or their counsel
may receive in writing from the SEC or its staff with respect to the Offer
Documents as soon as practicable after receipt of such written comments.

   144

     SECTION 1.2  Company Action.

     (a) The Company hereby represents that its Board of Directors, at a meeting
duly called and held on or prior to the date hereof, has by unanimous vote (i)
determined that this Agreement and the transactions contemplated hereby,
including the Offer and the Merger, are advisable and are fair to and in the
best interests of the Company and its stockholders, (ii) approved and adopted
this Agreement and the transactions contemplated hereby, including the Offer and
the Merger and the Stockholder Agreements and the transactions contemplated
thereby, which approval constitutes approval under Section 203 of the DGCL such
that the Offer, the Merger, this Agreement and the other transactions
contemplated hereby, and the Stockholder Agreements and the transactions
contemplated thereby, are not and shall not be subject to any restriction
pursuant to Section 203 of the DGCL, and (iii) resolved to recommend acceptance
of the Offer and approval and adoption of this Agreement by the Company's
stockholders (the unanimous recommendations referred to in this clause (iii) are
collectively referred to in this Agreement as the "Recommendations").

     (b) As soon as practicable on the day that the Offer is commenced, the
Company will file with the SEC and disseminate to holders of shares of Company
Common Stock a Solicitation/Recommendation Statement on Schedule 14D-9 (the
"Schedule 14D-9") which shall include the opinion of Credit Suisse First Boston
Corporation ("Credit Suisse First Boston") referred to in Section 3.17 hereof
and, subject to Section 5.4 hereof, shall include the Recommendations. Parent
shall promptly furnish to the Company all information concerning Parent,
Parent's Subsidiaries and Parent's stockholders that may be required or
reasonably requested in connection with any action contemplated by this Section
1.2(b). Subject to Section 5.4 hereof, the Company hereby consents to the
inclusion of the Recommendations in the Offer Documents and agrees that none of
the Recommendations shall be withdrawn, modified or changed in a manner adverse
to Parent or Merger Sub, and no resolution by the Board of Directors of the
Company or any committee thereof to withdraw, modify or change any of the
Recommendations in a manner adverse to Parent or Merger Sub shall be adopted or
proposed (it being understood that, for purposes of this Agreement, a
Recommendation shall be deemed to be withdrawn, modified or changed in a manner
adverse to Parent and Merger Sub if such Recommendation ceases to be unanimous).
Notwithstanding the foregoing, prior to the Appointment Time (as defined in
Section 1.3(a) hereof), the Board of Directors of the Company may withhold,
withdraw, modify or change in a manner adverse to Parent, or fail to make, its
Recommendations in accordance with the terms of Section 5.4 hereof. The Company,
Parent and Merger Sub each agree promptly to correct any information provided by
it for use in the Schedule 14D-9 if and to the extent that such information
shall have become false or misleading in any material respect. The Company
agrees to take all steps necessary to cause the Schedule 14D-9 as so corrected
to be filed with the SEC and to be disseminated to holders of shares of Company
Common Stock, in each case as and to the extent required by applicable federal
securities laws. Parent and its counsel shall be given a reasonable opportunity
to review and comment on the Schedule 14D-9 prior to its being filed with the
SEC. The Company agrees to provide Parent and its counsel with any comments the
Company or its counsel receives in writing from the SEC or its staff with
respect to the Schedule 14D-9 as soon as practicable after receipt of such
written comments.

     (c) The Company will promptly furnish Parent and Merger Sub with a list of
its stockholders, mailing labels and any available listing or computer file
containing the names and addresses of all record holders of shares of Company
Common Stock and lists of securities positions of shares of Company Common Stock
held in stock depositories, in each case as of the most recent practicable date,
and will provide to Parent and Merger Sub such additional information
(including, without limitation, updated lists of stockholders, mailing labels
and lists of securities positions) and such other assistance as Parent or Merger
Sub may reasonably request in connection with the Offer. Subject to the
requirements of applicable law, and except for such steps as are necessary to
disseminate the Offer Documents and any other documents necessary to consummate
the Offer, Parent and Merger Sub shall hold in confidence the information
contained in any such labels, listings and files, shall use such information
only in connection with the Offer and the Merger and, if this Agreement shall be
terminated, shall, upon request, deliver to the Company all copies of such
information then in their possession.

     SECTION 1.3  Directors.

     (a) Effective upon the acceptance for payment by Merger Sub of shares of
Company Common Stock pursuant to the Offer (the "Appointment Time"), Parent
shall be entitled to designate the number of directors, rounded up to the next
whole number, on the Company's Board of Directors that equals the product of (i)
the total number of directors on the Company's Board of Directors (giving effect
to the election of any additional directors pursuant to this Section 1.3) and
(ii) the percentage that the number of shares of Company Common Stock owned by
Parent or Merger Sub (including shares of Company Common Stock accepted for
payment) bears to the total number of shares of Company Common Stock
outstanding, and the Company shall take all action reasonably necessary to cause
Parent's designees to be elected or appointed to the Company's Board of
Directors, including, without limitation, at the option of Parent, increasing
the number of directors, or seeking and accepting resignations of incumbent
directors, or both; provided, however, that prior to the Effective Time, the
Company's Board of Directors shall always have at least two members who were
directors of the Company prior to consummation of the Offer (each, a "Continuing
Director"). If the number of Continuing Directors is reduced to fewer than two
for any reason prior to the Effective Time, the remaining and departing
Continuing Directors shall be entitled to designate a person to fill the
vacancy. Notwithstanding anything in this Agreement to the contrary, if Parent's
designees are elected to the Company's Board of Directors prior to the Effective
Time, the affirmative vote of a majority of the Continuing Directors shall be
required for the Company to (a) amend or terminate this Agreement or agree or
consent to any amendment or termination of this Agreement, (b) waive any of the
Company's rights, benefits or remedies hereunder, (c) extend the time for
performance of Parent's and Merger Sub's respective obligations hereunder, or
(d) approve any other action by the Company which is reasonably likely to
adversely affect the interests of the stockholders of the Company (other than
Parent, Merger Sub and their affiliates (other than the Company and its
Subsidiaries)) with respect to the transactions contemplated by this Agreement.

     (b) The Company's obligations to appoint designees to its Board of
Directors shall be subject to Section 14(f) of the Exchange Act and Rule 14f-l
promulgated thereunder. The Company shall promptly take all actions required
pursuant to this Section 1.3 and Rule 14f-l in order to fulfill its obligations
under this Section 1.3 and shall include in the Schedule 14D-9 such information
with respect to the Company and its officers and directors as is required under
Section 14(f) and Rule 14f-l. Parent will supply to the Company in writing and
be solely responsible for any information with respect to itself and its
nominees, officers, directors and affiliates required by Section 14(f) and Rule
14f-1.

     SECTION 1.4  The Merger.

     (a) Upon the terms and subject to the conditions of this Agreement, and in
accordance with the DGCL, at the Effective Time (as defined hereinafter), Merger
Sub shall be merged with and into the Company, whereupon the separate existence
of Merger Sub shall cease, and the Company shall continue as the surviving
corporation (sometimes referred to herein as the "Surviving Corporation").

     (b) Concurrently with the Closing (as defined in Section 1.8 hereof), the
Company and Parent shall cause a certificate of merger (the "Certificate of
Merger") with respect to the Merger to be executed and filed with the Secretary
of State of the State of Delaware (the "Secretary of State") as provided in the
DGCL. The Merger shall become effective on the date and time at which the
Certificate of Merger has been duly filed with the Secretary of State or at such
other date and time as is agreed between the parties and specified in the
Certificate of Merger, and such date and time is hereinafter referred to as the
"Effective Time."

     (c) The Merger shall have the effects set forth in the DGCL. Without
limiting the generality of the foregoing and subject thereto, from and after the
Effective Time, the Surviving Corporation shall possess all rights, privileges,
immunities, powers and franchises and be subject to all of the obligations,
restrictions, disabilities, liabilities, debts and duties of the Company and
Merger Sub.

     SECTION 1.5  Effect on Company Common Stock. At the Effective Time:

     (a) Cancellation of Shares of Company Common Stock. Each share of the
Company Common Stock held by the Company as treasury stock and each share of the
Company Common Stock owned by Parent or Merger Sub immediately prior to the
Effective Time shall automatically be cancelled and retired and cease to exist,
and no consideration or payment shall be delivered therefor or in respect
thereto. All shares of Company Common Stock to be converted into Parent Shares
pursuant to this Section 1.5 shall, by virtue of the Merger and without any
action on the part of the holders thereof, cease to be outstanding, be cancelled
and retired and cease to exist; and each holder of a certificate (representing
prior to the Effective Time any such shares of Company Common Stock) shall
thereafter cease to have any rights with respect to such shares of Company
Common Stock, except the right to receive (i) the Parent Shares into which such
shares of Company Common Stock have been converted, (ii) any dividend and other
distributions in accordance with Section 1.6(c) hereof, and (iii) any cash,
without interest, to be paid in lieu of any fraction of any Parent Shares in
accordance with Section 1.6(d) hereof.

     (b) Conversion of Shares of Company Common Stock. Subject to Sections
1.5(d) and 1.6(d) hereof, each share of Company Common Stock issued and
outstanding immediately prior to the Effective Time (other than shares of
Company Common Stock referred to in the first sentence of Section 1.5(a) hereof
and Dissenting Shares (as defined in Section 1.9 hereof) shall, by virtue of the
Merger and without any action on the part of the holder thereof, be converted
into that number of Parent Shares equal to the Exchange Ratio (together with the
cash in lieu of fractional shares of Parent Common Stock as specified below)
(the number of Parent Shares equal to the Exchange Ratio and the cash payable in
lieu of fractional shares as specified below being referred to as the "Merger
Consideration").

     (c) Capital Stock of Merger Sub. Each share of common stock, $0.001 par
value per share, of Merger Sub (the "Merger Sub Common Stock") issued and
outstanding immediately prior to the Effective Time shall be converted into one
(1) validly issued, fully paid and nonassessable share of common stock, $0.001
par value per share, of the Surviving Corporation. Each certificate evidencing
ownership of such shares of Merger Sub Common Stock shall evidence ownership of
shares of capital stock of the Surviving Corporation.

     (d) Adjustments to Exchange Ratio. The Exchange Ratio shall be adjusted to
reflect appropriately the effect of any stock split, reverse stock split, stock
dividend (including any dividend or distribution of securities convertible into
or exercisable or exchangeable for Company Common Stock or Parent Common Stock),
extraordinary cash dividend, reorganization, recapitalization, reclassification,
combination, exchange of shares or other like change with respect to Company
Common Stock or Parent Common Stock occurring or having a record date on or
after the date hereof and prior to the Effective Time.

     (e) Assumption of Company Options. At the Effective Time, each issued and
outstanding option to purchase or otherwise acquire Company Common Stock
(whether or not vested) ("Company Options") issued pursuant to the Company's
2000 Stock Plan or the Director Stock Option Plan (the "Option Plans") or
otherwise, will be assumed by Parent in connection with the Merger. Each Company
Option so assumed by Parent under this Agreement (the "Assumed Options") shall
continue to have, and be subject to, the same terms and conditions set forth in
the Option Plans and/or as provided in the respective option agreements
immediately prior to the Effective Time (including, without limitation, any
vesting schedule or repurchase rights), except that (i) each Company Option will
be exercisable for that number of Parent Shares equal to the product of the
number of shares of Company Common Stock that were issuable upon exercise of
such Company Option immediately prior to the Effective Time multiplied by the
Exchange Ratio, rounded down to the nearest whole number of Parent Shares, and
(ii) the per share exercise price for the Parent Shares issuable upon exercise
of such assumed Company Option will be equal to the quotient determined by
dividing the exercise price per share of Company Common Stock at which such
Company Option was exercisable immediately prior to the Effective Time by the
Exchange Ratio, rounded up to the nearest whole cent. Parent shall comply with
the terms of all such Company Options and use commercially reasonable efforts to
ensure, to the extent required by and subject to the provisions of, the Option
Plans, and to the extent permitted under the Code, that any Company Options that
qualified for

                                       A-5
   147

tax treatment as incentive stock options under Section 422 of the Code prior to
the Effective Time continue to so qualify after the Effective Time. Parent shall
take all corporate actions necessary to reserve for issuance a sufficient number
of shares of Parent Common Stock for delivery upon exercise of assumed Company
Options on the terms set forth in this Section 1.5(e).

     (f) Termination of Company Employee Stock Purchase Plan. Prior to the
Effective Time, the Company's Employee Stock Purchase Plan (the "Company ESPP")
shall be terminated. The rights of participants in the Company ESPP with respect
to any offering period then underway under the Company ESPP shall be determined
by treating the last business day prior to, or if administratively advisable,
last payroll date of the Company immediately prior to, the Effective Time, as
the last day of such offering period and by making such other pro-rata
adjustments as may be necessary to reflect the shortened offering period but
otherwise treating such shortened offering period as a fully effective and
completed offering period for all purposes under the Company ESPP. Prior to the
Effective Time, the Company shall take all actions (including, if appropriate,
amending the terms of the Company ESPP) that are necessary to give effect to the
transactions contemplated by this Section 1.5(f). Parent agrees that, from and
after the Effective Time, the employees of the Company who become employees of
Parent or any of its Subsidiaries may participate in the employee stock purchase
plan sponsored by Parent (the "Parent ESPP"), subject to the terms and
conditions of the Parent ESPP, and that service with the Company shall be
treated as service with Parent for determining eligibility of the Company's
employees under the Parent ESPP. Parent agrees to create a special offering
period under the Parent ESPP so that the employees of the Company who become
employees of Parent or any of its Subsidiaries can participate in the Parent
ESPP within fifteen (15) days from the Closing Date.

     (g) Assumption of Company Warrant. At the Effective Time, the outstanding
warrant issued by the Company to Thomson Multimedia S.A. (the "Warrant") will be
assumed by Parent in connection with the Merger. The Warrant shall continue to
have, and be subject to, the same terms and conditions set forth therein
(including, without limitation, the vesting schedule set forth therein), except
that (i) the Warrant will be exercisable for that number of shares of Parent
Common Stock equal to the product of the number of shares of Company Common
Stock that were issuable upon exercise of the Warrant immediately prior to the
Effective Time multiplied by the Exchange Ratio, rounded up to the nearest whole
number of shares of Parent Common Stock, and (ii) the per share exercise price
for the Parent Shares issuable upon exercise of the Warrant will be equal to the
quotient determined by dividing the exercise price per share of Company Common
Stock at which the Warrant was exercisable immediately prior to the Effective
Time by the Exchange Ratio, rounded up to the nearest whole cent.

     SECTION 1.6  Exchange of Certificates.

     (a) Prior to the mailing of any proxy or information statement of the
Company prepared in connection with the Merger (the "Proxy Statement"), such
bank, trust company, Person or Persons (as defined hereinafter) as shall be
designated by Parent and reasonably acceptable to the Company shall act as the
depositary and exchange agent for the delivery of the Merger Consideration in
exchange for shares of Company Common Stock (the "Exchange Agent") in connection
with the Merger. At or promptly following the Effective Time, Parent shall
deposit, or cause to be deposited, with the Exchange Agent the Merger
Consideration for the benefit of the holders of shares of Company Common Stock
which are converted into Parent Shares pursuant to Section 1.5(b) hereof
(together with cash as required to (i) pay any dividends or distributions with
respect thereto in accordance with Section 1.6(c) hereof and (ii) make payments
in lieu of fractional Parent Shares, pursuant to Section 1.6(d) hereof, being
hereinafter referred to as the "Exchange Fund"). For purposes of this Agreement,
"Person" means any natural person, firm, individual, corporation, limited
liability company, partnership, association, joint venture, company, business
trust, trust or any other entity or organization, whether incorporated or
unincorporated, including a government or political subdivision or any agency or
instrumentality thereof.

     (b) As of or promptly following the Effective Time but in no event later
than ten (10) business days thereafter, the Surviving Corporation shall cause
the Exchange Agent to mail (and to make available for collection by hand) to
each holder of record of a certificate or certificates, which immediately prior
to the

                                       A-6
   148

Effective Time represented outstanding shares of Company Common Stock (other
than Dissenting Shares) (the "Certificates"), (i) a letter of transmittal (which
shall specify that delivery shall be effected, and risk of loss and title to the
Certificates shall pass, only upon proper delivery of the Certificates to the
Exchange Agent and which shall be in the form and have such other provisions as
Parent and the Company may reasonably specify) and (ii) instructions for use in
effecting the surrender of the Certificates in exchange for the Merger
Consideration into which the number of shares of Common Stock previously
represented by such Certificates shall have been converted pursuant to this
Agreement (which instructions shall provide that at the election of the
surrendering holder, Certificates may be surrendered, and the Merger
Consideration in exchange therefor collected, by hand delivery). Upon surrender
of a Certificate for cancellation to the Exchange Agent, together with a letter
of transmittal duly completed and validly executed in accordance with the
instructions thereto, and such other documents as may be required pursuant to
such instructions, the holder of such Certificate shall be entitled to receive
in exchange therefor the Merger Consideration for each share of Common Stock
formerly represented by such Certificate, to be mailed (or made available for
collection by hand if so elected by the surrendering holder) within ten (10)
business days of receipt thereof (but in no case prior to the Effective Time),
and the Certificate so surrendered shall be forthwith cancelled. The Exchange
Agent shall accept such Certificates upon compliance with such reasonable terms
and conditions as the Exchange Agent may impose to effect an orderly exchange
thereof in accordance with normal exchange practices. No interest shall be paid
or accrued for the benefit of holders of the Certificates on the cash payable
pursuant to subsections (c) and (d) below upon the surrender of the
Certificates.

     (c) No cash payment in lieu of fractional Parent Shares shall be paid to
any Person pursuant to Section 1.6(d) hereof until such Person's Certificate is
surrendered in accordance with this Article I. Subject to the effect of
applicable laws, following surrender of any such Certificate, there shall be
paid, without interest, to the Person in whose name the Parent Shares being
issued in respect of such Certificate are to be registered (i) at the time of
such surrender, the amount of any cash payable in lieu of fractional Parent
Shares to which such holder is entitled pursuant to Section 1.6(d) hereof and
the proportionate amount of dividends or other distributions with a record date
after the Effective Time theretofore paid with respect to Parent Shares, and
(ii) at the appropriate payment date or as promptly as practicable thereafter,
the proportionate amount of dividends or other distributions with a record date
after the Effective Time but prior to such surrender and a payment date
subsequent to such surrender payable with respect to such Parent Shares.

     (d) Notwithstanding any other provision of this Agreement, no fraction of a
Parent Share will be issued and no dividend or other distribution, stock split
or interest with respect to Parent Shares shall relate to any fractional Parent
Shares, and such fractional interest shall not entitle the owner thereof to vote
or to any rights as a security holder of the Parent Shares. In lieu of any such
fractional security, each stockholder who would otherwise be entitled to receive
a fraction of a share of Parent Common Stock (after aggregating all fractional
shares of Parent Common Stock that otherwise would be received by such
stockholder) shall receive from Parent an amount of cash (rounded to the nearest
whole cent), without interest, equal to the product obtained by multiplying such
fraction by the average closing sale price of one (1) share of Parent Common
Stock on the NYSE during the ten (10) trading days ending on the trading day
immediately prior to the effective date of the Merger.

     (e) Any portion of the Exchange Fund which remains undistributed to the
holders of the Certificates for one (1) year after the Effective Time shall be
delivered to Parent, upon demand, and any holders of shares of Company Common
Stock prior to the Merger who have not theretofore complied with this Article I
shall thereafter look for payment of their claim, as general creditors thereof,
only to Parent for their claim for Parent Shares, any cash without interest, to
be paid, in lieu of any fractional Parent Shares and any dividends or other
distributions with respect to Parent Shares to which such holders may be
entitled.

     (f) None of Parent, the Company or the Exchange Agent shall be liable to
any Person in respect of any Parent Shares held in the Exchange Fund (or any
cash, dividends or other distributions payable in respect thereof) delivered to
a public official pursuant to any applicable abandoned property, escheat or
                                       A-7
   149

similar law. If any Certificates shall not have been surrendered prior to one
(1) year after the Effective Time (or immediately prior to such earlier date on
which (i) any Parent Shares, (ii) any cash in lieu of fractional Parent Shares
or (iii) any dividends or distributions with respect to Parent Shares in respect
of such Certificate would otherwise escheat to or become the property of any
Governmental Entity (as defined in Section 3.3(b) hereof)), any such Parent
Shares, cash, dividends or distributions in respect of such Certificate shall,
to the extent permitted by applicable law, become the property of Parent, free
and clear of any claims or interest of any Person previously entitled thereto.

     SECTION 1.7  Lost Certificates. If any Certificate shall have been lost,
stolen or destroyed, upon the making of an affidavit of that fact by the Person
claiming such Certificate to be lost, stolen or destroyed and, if required by
the Surviving Corporation, the posting by such Person of a bond, in such
reasonable amount as the Surviving Corporation may direct (but consistent with
past practice of the Company), as indemnity against any claim that may be made
against it with respect to such Certificate, the Exchange Agent will issue in
exchange for such lost, stolen or destroyed Certificate the Parent Shares to
which the holder thereof is entitled pursuant to this Article I.

     SECTION 1.8  Merger Closing. Subject to the satisfaction or waiver of the
conditions set forth in Article VI hereof, the closing of the Merger (the
"Closing") will take place at 10:00 a.m., California time, on a date to be
specified by the parties hereto, and no later than the second business day after
the satisfaction or waiver of the conditions set forth in Article VI hereof that
are to be satisfied other than on the day of the Closing, at the offices of
Wilson Sonsini Goodrich & Rosati, Professional Corporation, 650 Page Mill Road,
Palo Alto, California, unless another time, date or place is agreed to in
writing by the parties hereto (such date, the "Closing Date").

     SECTION 1.9  Dissenting Shares. If the Merger is effectuated pursuant to
Section 253 of the DGCL, shares of Company Common Stock outstanding immediately
prior to the Effective Time and held by a holder who is entitled to demand and
properly demands appraisal for such shares of Company Common Stock in accordance
with DGCL (the "Dissenting Shares") shall not be converted into a right to
receive Parent Shares, unless such holder fails to perfect or withdraws or
otherwise loses his or her right to appraisal. If after the Effective Time such
holder fails to perfect or withdraws or loses his or her right to appraisal,
such shares of Company Common Stock shall be treated as if they had been
converted as of the Effective Time into a right to receive the Merger
Consideration without any interest thereon. The Company shall give Parent prompt
notice of any demands received by the Company for appraisal of shares of Company
Common Stock, and Parent shall have the right to participate in all negotiations
and proceedings with respect to such demands. The Company shall not, except with
the prior written consent of Parent, make any payment with respect to, or settle
or offer to settle, any such demands. Any amounts paid to a holder pursuant to a
right of appraisal will be paid by the Company out of its own funds and will not
be reimbursed by Parent or any affiliate of Parent.

                           THE SURVIVING CORPORATION

     SECTION 2.1  Certificate of Incorporation. At the Effective Time, subject
to Section 5.5 hereof, the Certificate of Incorporation of the Surviving

Incorporation of the Surviving Corporation until thereafter amended in

     SECTION 2.2  Bylaws. At the Effective Time, subject to Section 5.5 hereof,

                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

     The Company represents and warrants to Parent and Merger Sub, subject to
such exceptions as are specifically disclosed in writing in the disclosure
schedule supplied by the Company to Parent prior to the execution of this
Agreement (the "Company Disclosure Schedule"), which disclosure shall provide an

Company specifically referred to in such disclosure schedule and such other
representations and warranties to the extent such disclosure shall reasonably
appear to be applicable to such other representations or warranties as follows:

     SECTION 3.1  Corporate Existence and Power. The Company is a corporation
duly incorporated, validly existing and in good standing under the laws of the
State of Delaware, and has all corporate powers and all governmental licenses,
authorizations, consents and approvals (collectively, "Licenses") required to
carry on its business as now conducted except for failures to have any such
License which would not, in the aggregate, have a Company Material Adverse
Effect (as defined hereinafter). The Company is duly qualified to do business as
a foreign corporation and is in good standing in each jurisdiction where the
character of the property owned, leased or operated by it or the nature of its
activities makes such qualification necessary, except in such jurisdictions
where failures to be so qualified would not reasonably be expected to, in the
aggregate, have a Company Material Adverse Effect. As used herein, the term
"Company Material Adverse Effect" means a material adverse effect on or change
in the financial condition, business, assets or results of operations of the
Company and its Subsidiaries, taken as a whole; provided, however, that in no
event shall any effect that directly results from (i) any change in general
economic conditions that does not affect the Company and its Subsidiaries, taken
as a whole, in a substantially disproportionate manner, (ii) any adverse change
affecting the semiconductor industry generally that does not affect the Company
and its Subsidiaries, taken as a whole, in a substantially disproportionate
manner, (iii) any failure by the Company to meet revenue and earnings estimates
in and of itself, and (iv) the announcement or pendency of this Agreement
constitute, or be considered in determining the existence of, a Company Material
Adverse Effect.

     The Company has heretofore made available to Parent true and complete
copies of the Certificate of Incorporation and the Bylaws of the Company as
currently in effect.

     SECTION 3.2  Corporate Authorization.

     (a) The Company has the requisite corporate power and authority to execute
and deliver this Agreement and, subject to approval of the Company's
stockholders, as set forth in Section 3.2(b) hereof and as contemplated by
Section 5.2 hereof, to perform its obligations hereunder. The execution and
delivery of this Agreement and the performance of the Company's obligations
hereunder have been duly and validly authorized, and this Agreement has been
approved, by the Board of Directors of the Company and no other corporate
proceedings, on the part of the Company, other than the approval of the
Company's stockholders, are necessary to authorize the execution, delivery and
performance of this Agreement. This Agreement has been duly executed and
delivered by the Company and constitutes, assuming due authorization, execution
and delivery of this Agreement by Parent and Merger Sub, a valid and binding
obligation of the Company, enforceable against the Company in accordance with
its terms.

   151

     (b) Under applicable law, the Certificate of Incorporation and the rules of
The Nasdaq National Market, the affirmative vote of the holders of a majority of
the shares of Company Common Stock outstanding on the record date, established
by the Board of Directors of the Company in accordance with the Bylaws of the
Company, applicable law and this Agreement, is the vote required to approve the
Merger and adopt this Agreement.

     SECTION 3.3  Consents and Approvals; No Violations.

     (a) Neither the execution and delivery of this Agreement nor the
performance by the Company of its obligations hereunder will (i) conflict with
or result in any breach of any provision of the Certificate of Incorporation or
the Bylaws of the Company; (ii) result in a violation or breach of, or
constitute (with or without due notice or lapse of time or both) a default (or
give rise to any right of termination, cancellation or acceleration or
obligation to repurchase, repay, redeem or acquire or any similar right or
obligation) under any of the terms, conditions or provisions of any Company
Contract or (iii) assuming that the filings, registrations, notifications,
authorizations, consents and approvals referred to in subsection (b) below have
been obtained or made, as the case may be, violate any order, injunction,
decree, statute, rule or regulation of any Governmental Entity to which the
Company or any of its Subsidiaries is subject, excluding from the foregoing
clauses (ii) and (iii) such requirements, defaults, breaches, rights or
violations (A) that would not, in the aggregate, reasonably be expected to have
a Company Material Adverse Effect and would not have a material adverse effect
on the ability of the Company to perform its obligations hereunder or (B) that
become applicable as a result of the business or activities in which Parent or
any of its affiliates is or proposes to be engaged or any acts or omissions by,
or facts specifically pertaining to, Parent.

     (b) No filing or registration with, notification to, or authorization,
consent or approval of, any government or any agency, court, tribunal,
commission, board, bureau, department, political subdivision or other
instrumentality of any government (including any regulatory or administrative

the Company of its obligations hereunder, except (i) the filing of the
Certificate of Merger in accordance with the DGCL; (ii) compliance with any

approvals, orders, authorizations, notifications, registrations, declarations
and filings (A) the failure of which to be obtained or made would not, in the
aggregate, reasonably be expected to have a Company Material Adverse Effect and
would not have a material adverse effect on the ability of the Company to
perform its obligations hereunder or (B) that become applicable as a result of
the business or activities in which Parent or any of its affiliates is or
proposes to be engaged or any acts or omissions by, or facts specifically
pertaining to, Parent.

     SECTION 3.4  Capitalization. The authorized capital stock of the Company
consists of 200,000,000 shares of Company Common Stock and 10,000,000 shares of

Company Common Stock issued and outstanding and (ii) no shares of Preferred

stock options, and the forms of all stock option agreements evidencing such
options. The Company has made available to Parent accurate and complete copies

     SECTION 3.5  Subsidiaries.

     (a) Each Subsidiary of the Company that is actively engaged in any business
or owns any material assets (each, an "Active Company Subsidiary") (i) is a
corporation duly incorporated, validly existing and in good standing under the
laws of its jurisdiction of incorporation, (ii) has all corporate powers and all
material governmental licenses, authorizations, consents and approvals required
to carry on its business as now conducted and (iii) is duly qualified to do
business as a foreign corporation and is in good standing in each jurisdiction
where the character of the property owned or leased by it or the nature of its
activities makes such qualification necessary, except for failures of this
representation and warranty to be true which would not, in the aggregate, have a
Company Material Adverse Effect. For purposes of this Agreement, "Subsidiary"
means with respect to any Person, any corporation or other legal entity of which
such Person owns, directly or indirectly, more than 50% of the outstanding stock
or other equity interests, the holders of which are entitled to vote for the

or other legal entity. All Subsidiaries of the Company and their respective
jurisdictions of incorporation are identified in Schedule 3.5 of the Company
Disclosure Schedule.

     (b) All of the outstanding shares of capital stock of each Subsidiary of
the Company are duly authorized, validly issued, fully paid and nonassessable,
and such shares are owned by the Company or by a Subsidiary of the Company free
and clear of any Liens (as defined in this Section 3.5) or limitations on voting
rights. There are no subscriptions, options, warrants, calls, rights,
convertible securities or Contracts of any character relating to the issuance,
transfer, sale, delivery, voting or redemption (including any rights of
conversion or exchange under any outstanding security or other instrument) for
any of the capital stock or other equity interests of any of such Subsidiaries.
There are no Contracts requiring the Company or any of its Subsidiaries to make
contributions to the capital of, or lend or advance funds to, any Subsidiaries
of the Company. For purposes of this Agreement, "Lien" means, with respect to
any asset, any mortgage, lien, pledge, charge, security interest or encumbrance
of any kind in respect of such asset.

will be required to permit the Company to conduct the business as conducted by
the Company and its Subsidiaries immediately prior to the Closing Date.

     SECTION 3.16  Intellectual Property.

     (a) To the knowledge of the Company, the Company and its Subsidiaries own
or have a valid right to use all Intellectual Property (as defined hereinafter)
used by or reasonably necessary for the Company and its Subsidiaries to conduct
their business as it is currently conducted. Schedule 3.16(a)(i) of the Company
Disclosure Schedule sets forth, with respect to each item of Intellectual
Property owned by the Company or any of its Subsidiaries and registered with any
Governmental Entity, or for which an application has been filed and is currently
pending with any Governmental Entity, (i) a brief description of such item of
Intellectual Property, and (ii) the names of the jurisdictions covered by the
applicable registration or application. The Company and its Subsidiaries have
good, valid and exclusive title to all of the Intellectual Property
registrations and applications identified or required to be identified in
Schedule 3.16(a)(i) of the Company Disclosure Schedule, free and clear of all
liens, claims and encumbrances of any nature, except for (i) any lien for
current taxes not yet due and payable, and (ii) minor liens that have arisen in
the ordinary course of business and that do not (individually or in the
aggregate) materially detract from the value of the Intellectual Property
subject thereto or materially impair the operations of Company or any of its
Subsidiaries. Neither Company nor any of its Subsidiaries has developed jointly
with any other Person any Intellectual Property that is material to the business
of Company or its Subsidiaries and the loss of which would constitute a Company
Material Adverse Effect and with respect to which such other Person has any
rights to restrict the Company's use of such Intellectual Property. Neither the
Company nor any of its Subsidiaries has licensed any Intellectual Property owned
by or exclusively licensed to Company or any of its Subsidiaries and material to
the business of the Company or its Subsidiaries to any Person on an exclusive
basis.

     (b) To the knowledge of the Company: (i) all of the applications and
registrations relating to Intellectual Property owned by or exclusively licensed
to the Company and its Subsidiaries set forth in Schedule 3.16(a)(i) are
subsisting and unexpired, free of all liens, claims, or encumbrances of any
nature, and have not been abandoned in any respect; (ii) the Company and its
Subsidiaries, and all products manufactured, distributed or sold by the Company
or any of its Subsidiaries, have not infringed and do not infringe the
intellectual property rights (including, but not limited to, patent rights,
copyrights, maskwork rights, trademark and similar rights, and trade secret
rights) of any third party in any respect that would reasonably be expected to
have, individually or in the aggregate, a Company Material Adverse Effect; (iii)
no judgment, decree, injunction, rule or order has been rendered by any
Governmental Entity which would or does limit, cancel or question the validity
of, or the Company's or its Subsidiaries' rights in and to, any Intellectual
Property owned by or exclusively licensed to the Company in any respect that
would
                                       A-18
   160

reasonably be expected to have, individually or in the aggregate, a Company
Material Adverse Effect; and (iv) neither the Company nor any of its
Subsidiaries has received notice of any pending or threatened suit, action or
proceeding that seeks to limit, cancel or question the validity of, or the
Company's or its Subsidiaries' rights in and to, any Intellectual Property,
which would reasonably be expected to have, individually or in the aggregate, a
Company Material Adverse Effect, and, to the Company's knowledge, there is no
basis for any such suit, action or proceeding. To the knowledge of the Company,
no other Person is infringing, misappropriating or making any unlawful or
unauthorized use of, and no Intellectual Property owned or used by any other
Person infringes or conflicts with, any Intellectual Property owned by or
exclusively licensed to the Company or any of its Subsidiaries and material to
the business of the Company or its Subsidiaries.

     (c) To the knowledge of the Company, the Company and its Subsidiaries have
not used and are not making use of any confidential or proprietary information
or trade secrets of any other Person in breach of any Company Contract or in
violation of any civil or criminal law.

     (d) The Company and its Subsidiaries have taken commercially reasonable
security measures to protect the secrecy, confidentiality and value of their
trade secrets, the loss or public disclosure of which would cause a Company
Material Adverse Effect (the "Material Trade Secrets"). Without limiting the
generality of the preceding sentence, neither the Company nor any of its
Subsidiaries has, to the best of their knowledge, disclosed any of their
Material Trade Secrets to any other Person who is not subject to binding
confidentiality obligations that restrict the further disclosure of such
Material Trade Secrets. Without limiting the generality of the foregoing, to the
knowledge of the Company, (i) each current or former employee of the Company or
any of its Subsidiaries who is or was involved on behalf of the Company or any
of its Subsidiaries in, or who has contributed on behalf of the Company or any
of its Subsidiaries to, the creation or development of any material Intellectual
Property owned or used by the Company or any of its Subsidiaries has executed
and delivered to the Company or the applicable Subsidiary of the Company an
agreement (containing no material exceptions to or exclusions from the scope of
its coverage deviating from the form referred to below in this clause (i) that
is substantially identical to the form of Confidential Information and Invention
Assignment Agreement previously delivered by the Company to Parent, and (ii)
each current and former consultant and independent contractor to the Company or
any of its Subsidiaries who is or was involved on behalf of the Company or any
of its Subsidiaries in, or who has contributed on behalf of the Company or any
of its Subsidiaries to, the creation or development of any material Intellectual
Property owned or used by the Company or any of its Subsidiaries has executed
and delivered to the Company or the applicable Subsidiary of the Company an
agreement (containing no material exceptions to or exclusions from the scope of
its coverage deviating from the form referred to below in this clause (ii) that
is substantially identical to the form of Consultant Confidential Information
and Invention Assignment Agreement previously delivered by the Company to
Parent. To the Company's knowledge, no current or former employee, officer,
director, stockholder, consultant or independent contractor has any right, claim
or interest in or with respect to any material Intellectual Property owned by or
exclusively licensed to the Company or any of its Subsidiaries that restricts
the Company's ability to use or otherwise fully exploit such Intellectual
Property. To the Company's knowledge, no employee of the Company or any
Subsidiary of the Company has entered into any agreement that restricts or
limits in any way the scope or type of work in which the employee may be engaged
in a manner materially adverse to the Company's business or requires the
employee to transfer, assign or disclose any Intellectual Property or
information concerning the employee's work for the Company or any Subsidiary of
the Company to anyone other than the Company or any Subsidiary of the Company.

     (e) For purposes of this Agreement "Intellectual Property" shall mean all
rights, privileges and priorities provided under U.S., state and foreign law
relating to intellectual property, including without limitation all: (x) (1)
proprietary inventions, discoveries, processes, formulae, designs, methods,
techniques, procedures, concepts, developments, technology, improvements and
modifications thereof and proprietary know-how relating thereto, whether or not
patented or eligible for patent protection; (2) copyrights and copyrightable
works, including, but not limited to, computer applications, programs,

                                       A-19
   161

software, netlists, RTL tapeouts, test vectors, reference designs, schematics,
databases and related items; (3) trademarks, service marks, trade names, and
trade dress, the goodwill of any business symbolized thereby, and all common-law
rights relating thereto; (4) trade secrets and other confidential information;
and (5) semiconductor chip mask works; (y) all registrations, applications and
recordings for any of the foregoing and continuations, continuations-in-part,
counterparts, divisionals, reexaminations, and reissues of any of the foregoing;
and (z) licenses or other similar agreements granting to the Company or any of
its Subsidiaries the rights to use any of the foregoing.

     SECTION 3.17  Opinion of Financial Advisor. The Company has received the
opinion of Credit Suisse First Boston to the effect that, as of the date of such
opinion, and based upon and subject to the matters stated therein, the Exchange
Ratio is fair from a financial point of view to the holders of Company Common
Stock (other than Parent and its affiliates).

     SECTION 3.18  Board Recommendation. The Board of Directors of the Company
has, as of the date of this Agreement, by unanimous vote (i) determined that
this Agreement and the transactions contemplated hereby, including the Offer and
the Merger, are advisable and are fair to and in the best interests of the
Company and its stockholders, (ii) approved and adopted this Agreement and the
transactions contemplated hereby, including the Offer and the Merger and the
Stockholder Agreements and the transactions contemplated thereby, and (iii)
resolved to recommend acceptance of the Offer and approval and adoption of this
Agreement by the Company's stockholders.

     SECTION 3.19  Tax Treatment. Neither the Company nor any of its affiliates
has taken any action or knows of any fact, agreement, plan or other circumstance
that is reasonably likely to prevent the Transaction from qualifying as a
reorganization under the provisions of Section 368(a) of the Code.

     SECTION 3.20  Finders' Fees. Except for Credit Suisse First Boston, whose
fees will be paid by the Company, there is no investment banker, broker, finder
or other intermediary which has been retained by, or is authorized to act on
behalf of, the Company or any Subsidiary of the Company that would be entitled
to any fee or commission from the Company, any Subsidiary of the Company, Parent
or any of Parent's affiliates upon consummation of the transactions contemplated
by this Agreement. The Company has furnished to Parent accurate and complete
copies of all agreements under which any such fees, commissions or other amounts
have been paid to or may become payable and all indemnification and other
agreements related to the engagement of Credit Suisse First Boston.

     SECTION 3.21  Section 203 of the Delaware General Corporation Law. The
Board of Directors of the Company has taken all actions so that the restrictions
contained in Section 203 of the DGCL applicable to a "business combination" (as
defined in such Section 203) will not apply to the execution, delivery or
performance of this Agreement or the Stockholder Agreements or to the
consummation of the Offer or the Merger or the other transactions contemplated
by this Agreement or the Stockholder Agreements.

                                   ARTICLE IV

            REPRESENTATIONS AND WARRANTIES OF PARENT AND MERGER SUB

     Parent and Merger Sub, jointly and severally represent and warrant to the
Company, subject to such exceptions as are specifically disclosed in writing in
the disclosure schedule supplied by Parent and Merger Sub to the Company prior
to the execution of this Agreement (the "Parent Disclosure Schedule"), which
disclosure shall provide an exception to or otherwise qualify the
representations or warranties of Parent specifically referred to in such
disclosure and such other representations and warranties to the extent such
disclosure shall reasonably appear to be applicable to such other
representations or warranties, as follows:

     SECTION 4.1  Corporate Existence and Power. Each of Parent and Merger Sub
is a corporation duly incorporated (or other entity duly organized), validly
existing and in good standing under the laws of its jurisdiction of
incorporation, has all corporate or other power, as the case may be, and all
Licenses required to carry on its business as now conducted except for failures
to have any such License which
                                       A-20
   162

would not, in the aggregate, have a Parent Material Adverse Effect (as defined
in this Section 4.1). Parent is duly qualified to do business and is in good
standing in each jurisdiction where the character of the property owned, leased
or operated by it or the nature of its activities makes such qualification
necessary, except for those jurisdictions where failures to be so qualified
would not reasonably be expected to, in the aggregate, have a Parent Material
Adverse Effect. As used herein, the term "Parent Material Adverse Effect" means
a material adverse effect on or change in the financial condition, business,
assets or results of operations of Parent and its Subsidiaries, taken as a
whole; provided, however, that in no event shall any effect that directly
results from (i) any change in general economic conditions that does not affect
Parent and its Subsidiaries, taken as a whole, in a substantially
disproportionate manner, (ii) any adverse change affecting the semiconductor
industry generally that does not affect Parent and its Subsidiaries taken as a
whole, in a substantially disproportionate manner, (iii) any failure by Parent
to meet revenue and earnings estimates in and of itself, and (iv) the
announcement or pendency of this Agreement, constitute, or be considered in
determining the existence of, a Parent Material Adverse Effect. Parent has
heretofore delivered or made available to the Company true and complete copies
of the governing documents or other organizational documents of like import, as
currently in effect, of Parent.

     SECTION 4.2  Authorization. Each of Parent and Merger Sub has the requisite
power and authority to execute and deliver this Agreement and to perform its
obligations hereunder. The execution and delivery of this Agreement and the
performance of its obligations hereunder have been duly and validly authorized
by both the Board of Directors of Parent and the Board of Directors of Merger
Sub, and no other proceedings on the part of Parent, including stockholder
approval, or on the part of Merger Sub are necessary to authorize the execution,
delivery and performance of this Agreement. This Agreement has been duly
executed and delivered by Parent and Merger Sub and constitutes, assuming due
authorization, execution and delivery of this Agreement by the Company, a valid
and binding obligation of Parent and Merger Sub, respectively enforceable
against each entity in accordance with its terms.

     SECTION 4.3  Consents and Approvals; No Violations.

     (a) Neither the execution and delivery of this Agreement nor the
performance by Parent or Merger Sub of its respective obligations hereunder will
(i) conflict with or result in any breach of any provision of the Certificate of
Incorporation or Bylaws (or other governing or organizational documents) of
Parent or of Merger Sub, as applicable, or (ii) result in a violation or breach
of, or constitute (with or without due notice or lapse of time or both) a
default (or give rise to any right of termination, cancellation or acceleration
or obligation to repurchase, repay, redeem or acquire or any similar right or
obligation) under any of the terms, conditions or provisions of any Contract to
which Parent or Merger Sub is a party or by which any of them or any of the
respective assets used or held for use by any of them may be bound or (iii)
assuming that the filings, registrations, notifications, authorizations,
consents and approvals referred to in subsection (b) below have been obtained or
made, as the case may be, violate any order, injunction, decree, statute, rule
or regulation of any Governmental Entity to which Parent or Merger Sub is
subject, excluding from the foregoing clauses (ii) and (iii) such requirements,
defaults, breaches, rights or violations (A) that would not, in the aggregate,
reasonably be expected to have a Parent Material Adverse Effect and would not
reasonably be expected to have a material adverse effect on the ability of
Parent to consummate the transactions contemplated hereby or (B) that become
applicable as a result of any acts or omissions by, or facts specifically
pertaining to, the Company.

     (b) No filing or registration with, notification to, or authorization,
consent or approval of, any Governmental Entity is required in connection with
the execution and delivery of this Agreement by Parent or by Merger Sub or the
performance by either entity of its obligations hereunder, except (i) the filing
of the Certificate of Merger in accordance with the DGCL; (ii) compliance with
any applicable requirements of the HSR Act or any foreign laws regulating
competition, antitrust, investment or exchange controls; (iii) compliance with
any applicable requirements of the Securities Act and the Exchange Act; (iv)
compliance with any applicable requirements of state blue sky or takeover laws
and (v) such other consents, approvals, orders, authorizations, notifications,
registrations, declarations and filings (A) the failure of which to be obtained
or made would not reasonably be expected to have a Parent Material Adverse
Effect and would not have a material adverse effect on the ability of Parent or
of Merger Sub to
                                       A-21
   163

perform its obligations hereunder or (B) that become applicable as a result of
any acts or omissions by, or facts specifically pertaining to, the Company.

     SECTION 4.4  Capitalization. The authorized capital stock of Parent
consists of 1,300,000,000 shares of Parent Common Stock and 2,000,000 shares of
preferred stock of Parent (the "Parent Preferred Stock"). The authorized capital
stock of Merger Sub consists of 1,000 shares of Merger Sub Common Stock, 100
shares of which, as of the date hereof, are issued and outstanding and are held
by Parent. As of March 16, 2001, there were (i) 322,528,165 shares of Parent
Common Stock issued and outstanding and (ii) no shares of Parent Preferred Stock

have been duly authorized and validly issued and are fully paid and
nonassessable and were not issued in violation of any preemptive rights. As of
March 16, 2001, there were outstanding options to purchase approximately
60,400,000 shares of Parent Common Stock. Except as set forth in this Section
4.4 and except for changes since March 16, 2001, resulting from the exercise of
options to purchase shares of Parent Common Stock outstanding on such date, as
of the date of this Agreement there are outstanding (i) no shares of capital
stock or other voting securities of Parent, (ii) no securities of Parent or any
Subsidiary of Parent convertible into or exchangeable for shares of capital
stock or voting securities of Parent and (iii) no options or other rights to
acquire from Parent, and no obligation of Parent to issue, any capital stock,
voting securities or securities convertible into or exchangeable for capital
stock or voting securities of Parent (the items in clauses (i), (ii) and (iii)
being referred to collectively as the "Parent Securities"). As of the date of
this Agreement, there are no outstanding obligations of Parent or any of its
Subsidiaries to repurchase, redeem or otherwise acquire any Parent Securities.
No Subsidiary of Parent owns any capital stock or other voting securities of
Parent.

     SECTION 4.5  SEC Documents. Parent has filed all required reports, proxy
statements, registration statements, forms and other documents with the SEC
since January 1, 2000 (the "Parent SEC Documents"). As of their respective
dates, and giving effect to any amendments thereto, (a) the Parent SEC Documents
complied in all material respects with the requirements of the Securities Act or
the Exchange Act, as the case may be, and the applicable rules and regulations
of the SEC promulgated thereunder and (b) none of the Parent SEC Documents
contained any untrue statement of a material fact or omitted to state any
material fact required to be stated therein or necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading.

     SECTION 4.6  Financial Statements. The financial statements of Parent
(including, in each case, any notes and schedules thereto) included in the
Parent SEC Documents (a) were prepared from the books and records of Parent and
its Subsidiaries, (b) comply as to form in all material respects with all
applicable accounting requirements and the rules and regulations of the SEC with
respect thereto, (c) are in conformity with GAAP, applied on a consistent basis
(except in the case of unaudited statements, as permitted by the rules and
regulations of the SEC) and (d) fairly present, in all material respects, the
consolidated financial position of Parent and its consolidated Subsidiaries as
of the dates thereof and the consolidated results of their operations and cash
flows for the periods then ended (subject, in the case of unaudited statements,
to normal year-end audit adjustments which were not and are not expected to be,
individually or in the aggregate, material in amount).

     SECTION 4.7  Disclosure Documents. Neither the Offer Documents nor the
Registration Statement nor the Post-Effective Amendment, nor any of the
information supplied or to be supplied by Parent or its Subsidiaries or
Representatives for inclusion or incorporation by reference in the Schedule
14D-9 or the Proxy Statement will, at the respective times any such documents or
any amendments or supplements thereto are filed with the SEC, are first
published, sent or given to stockholders or become effective under the
Securities Act or, in the case of the Proxy Statement, at the time of the
Company Special Meeting, contain any untrue statement of a material fact or omit
to state any material fact required to be stated therein or necessary to make
the statements therein not misleading. The Offer Documents and the Registration
Statement and the Post-Effective Amendment will comply as to form in all
material respects with the requirements of all applicable laws, including the
Securities Act and the Exchange Act and the rules and regulations thereunder. No
representation or warranty is made by Parent or Merger Sub with

                                       A-22
   164

respect to statements made or incorporated by reference in any such documents
based on information supplied by the Company for inclusion or incorporation by
reference therein.

     SECTION 4.8  Absence of Material Adverse Changes, Etc. Since December 31,
2000 there has not been any Parent Material Adverse Effect and no event has
occurred or circumstance has arisen that would reasonably be expected to have a
Parent Material Adverse Effect.

     SECTION 4.9  Litigation; Compliance With Laws.

     (a) Except as set forth in the Parent SEC Documents filed through the date
of this Agreement, there is no action, suit or proceeding pending against, or to
the knowledge of Parent threatened against, Parent or any Subsidiary of Parent
or any of their respective properties before any court or arbitrator or any
Governmental Entity which would reasonably be expected to have a Parent Material
Adverse Effect.

     (b) Parent and its Subsidiaries are in compliance with all applicable laws,
ordinances, rules and regulations of any federal, state, local or foreign
governmental authority applicable to their respective businesses and operations,
except for such violations, if any, which, in the aggregate, would not
reasonably be expected to have a Parent Material Adverse Effect. All Permits
required to conduct the business of Parent and its Subsidiaries have been
obtained, are in full force and effect and are being complied with except for
such violations and failures to have Permits in full force and effect, if any,
which, individually or in the aggregate, would not reasonably be expected to
have a Parent Material Adverse Effect.

     SECTION 4.10  Tax Treatment. Neither Parent nor any of its affiliates has
taken any action or knows of any fact, agreement, plan or other circumstance
that is reasonably likely to prevent the Transaction from qualifying as a
reorganization under the provisions of Section 368(a) of the Code.

     SECTION 4.11  Interim Operations of Merger Sub. Merger Sub was formed
solely for the purpose of engaging in the transactions contemplated by this
Agreement and has not engaged in any business activities or conducted any
operations other than in connection with the transactions contemplated by this
Agreement.

                                   ARTICLE V

     (a) If approval of the Company's stockholders is required by applicable law
in order to consummate the Merger other than pursuant to Section 253 of DGCL,
Parent and the Company shall, as soon as

                                       A-24
   166

practicable following the Appointment Time, prepare and the Company shall file

Parent shall file with the SEC a post-effective amendment to the Registration
Statement (the "Post-Effective Amendment") for the offer and sale of Parent
Shares pursuant to the Merger and in which the Proxy Statement will be included
as a prospectus. Each of the Company and Parent shall use commercially
reasonable efforts to have the Post-Effective Amendment declared effective under
the Securities Act as promptly as practicable after such filing. The Company
will use commercially reasonable efforts to cause the Proxy Statement to be
mailed to the Company's stockholders as promptly as practicable after the
Post-Effective Amendment is declared effective under the Securities Act. Parent

jurisdiction in which it is not now so qualified or filing a general consent to
service of process) required to be taken under any applicable state securities
laws in connection with the issuance of Parent Shares in the Merger and the
Company shall furnish all information concerning the Company and the holders of
capital stock of the Company as may be reasonably requested in connection with
any such action and the preparation, filing and distribution of the Proxy
Statement. No filing of, or amendment or supplement to, or correspondence to the
SEC or its staff with respect to, the Post-Effective Amendment will be made by
Parent, or with respect to the Proxy Statement will be made by the Company,
without providing the other party a reasonable opportunity to review and comment
thereon. Parent will advise the Company, promptly after it receives notice
thereof, of the time when the Post-Effective Amendment has become effective or
any supplement or amendment has been filed, the issuance of any stop order, the
suspension of the qualification of the Parent Common Stock issuable in
connection with the Merger for offering or sale in any jurisdiction, or any
request by the SEC for amendment of the Post-Effective Amendment or comments
thereon and responses thereto or requests by the SEC for additional information.
The Company will advise Parent, promptly after it receives notice thereof, of
any request by the SEC for the amendment of the Proxy Statement or comments
thereon and responses thereto or requests by the SEC for additional information.
If at any time prior to the Effective Time any information relating to the
Company or Parent, or any of their respective affiliates, officers or directors,
should be discovered by the Company or Parent which should be set forth in an
amendment or supplement to either of the Post-Effective Amendment or the Proxy
Statement, so that any of such documents would not include any misstatement of a
material fact or omit to state any material fact necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading, the party which discovers such information shall promptly notify
the other parties hereto and an appropriate amendment or supplement describing
such information shall be promptly filed with the SEC and, to the extent
required by law, disseminated to the stockholders of the Company.

     (b) If approval of the Company's stockholders is required by applicable law
in order to consummate the Merger, other than pursuant to Section 253 of the
DGCL, the Company shall establish, prior to or as soon as practicable following
the date upon which the Post-Effective Amendment becomes effective, a record
date (which shall be prior to or as soon as practicable following the date upon
which the Post-Effective Amendment becomes effective) for, duly call, give
notice of, convene and hold a meeting of its stockholders (the "Company Special
Meeting") for the purpose of considering the approval and adoption of this
Agreement and (with the consent of Parent) such other matters as may in the
reasonable judgment of the Company be appropriate for consideration at the
Company Special Meeting. Once the Company Special Meeting has been called and
noticed, the Company shall not postpone or adjourn the Company Special Meeting
(other than for the absence of a quorum) without the consent of Parent. The
Post-Effective Amendment and the Proxy Statement shall include the opinion of
Credit Suisse First Boston referred to in Section 3.17 hereof and, subject to
the Company's right, pursuant to Section 5.4 hereof, to withhold, withdraw,
modify, change or fail to make the Recommendations, the Board of Directors of
the Company shall include in the Post-Effective Amendment and the Proxy
Statement the Recommendations. Unless the Board of Directors of the Company
shall have withheld, withdrawn, modified, changed or failed to make its
Recommendations in compliance with Section 5.4, the Company shall use
commercially reasonable efforts to take all actions necessary or advisable to
secure the vote or consent of stockholders required by the DGCL to effect the
Offer and the Merger. Notwithstanding anything to the contrary contained in this
Agreement, the Company's obligation to establish a record date for, call, give
notice of,

                                       A-25
   167

convene and hold the Company Special Meeting in accordance with this Section
5.2(b) shall not be limited by or otherwise affected by the commencement,
disclosure, announcement or submission of any Acquisition Proposal (as defined
hereinafter).

     (c) The Company and Parent shall cooperate with one another (i) in
connection with the preparation of the Proxy Statement and the Registration
Statement, (ii) in determining whether any action by or in respect of, or filing
with, any Governmental Entity is required, or any actions, consents, approvals
or waivers are required to be obtained from parties to any material contracts,
in connection with the consummation of the transactions contemplated by this
Agreement and (iii) in seeking any such actions, consents, approvals or waivers
or making any such filings, furnishing information required in connection
therewith or with the Proxy Statement and the Registration Statement and seeking
timely to obtain any such actions, consents, approvals or waivers.

     (d) Notwithstanding clauses (a) and (b) above, if Merger Sub shall own by
virtue of the Offer or otherwise at least 90% of the outstanding shares of
Company Common Stock, the parties hereto shall take all necessary actions
(including actions referred to in clause (a) above, as applicable) to cause the
Merger to become effective, as soon as practicable after the expiration of the
Offer, as it may be extended in accordance with the requirements of Section
1.1(a) hereof, without a meeting of stockholders of the Company, in accordance
with Section 253 of the DGCL.

     SECTION 5.3  Access to Information; Confidentiality Agreement. Upon
reasonable advance notice, between the date hereof and the Closing Date, each of
the Company and Parent shall (i) give the other, its respective counsel,
financial advisors, auditors and other authorized representatives (collectively,
"Representatives") reasonable access during normal business hours to the
offices, properties, books and records of such party and its Subsidiaries, (ii)
furnish to the other and the other's Representatives such financial and
operating data and other information relating to such party, its Subsidiaries
and their respective operations as such Persons may reasonably request and (iii)
instruct such party's employees, counsel and financial advisors to cooperate
with the other in its investigation of the business of such party and its
Subsidiaries; provided that any information and documents received by the other
party or its Representatives (whether furnished before or after the date of this
Agreement) shall be held in accordance with the Confidentiality Agreement dated
as of March 16, 2001 between Parent and the Company (the "Confidentiality
Agreement"), which, subject to Section 8.10, shall remain in full force and
effect until the Effective Time pursuant to the terms thereof, notwithstanding
the execution and delivery of this Agreement or the termination hereof.

     SECTION 5.4  No Solicitation. From the date hereof until the Effective Time
or, if earlier, the termination of this Agreement, the Company shall not,
whether directly or indirectly through its respective officers, directors,
advisors, Representatives or other agents, (a) solicit, initiate or encourage
any Acquisition Proposal (as defined hereinafter); (b) engage in discussions or
negotiations with, or disclose any non-public information relating to the
Company or its Subsidiaries or afford access to the properties, books or records
of the Company or its Subsidiaries to, any Person (other than Parent or any
designees of Parent) concerning or in connection with an Acquisition Proposal,
(c) withhold, withdraw, modify or change in a manner adverse to Parent, or fail
to make, any of its Recommendations or approve, endorse or recommend an
Acquisition Proposal or (d) release or permit the release of any Person from, or
waive or permit the waiver of any provision of, any confidentiality,
"standstill" or similar agreement (other than as required pursuant to the terms
thereof as in effect on the date hereof) under which the Company or any of its
Subsidiaries has any rights, or fail to use commercially reasonable efforts to
enforce or cause to be enforced each such agreement at the request of Parent;
provided, however, that in each case, if (i) after the date of this Agreement,
an unsolicited, bona fide written Acquisition Proposal is made to the Company
and is not withdrawn; (ii) the Company provides Parent with prior notice of any
meeting of the Company's Board of Directors (which notice shall be given at the
same time notice is given to the Company's directors) at which such Board of
Directors will consider and determine whether such Acquisition Proposal is, or
could reasonably be expected to be, a Superior Proposal (as defined
hereinafter); (iii) the Company's Board of Directors believes in good faith,
after consultation with the Company's financial advisor, that such Acquisition
Proposal is, or could reasonably be expected to be, a
                                       A-26
   168

Superior Proposal; (iv) the Company's Board of Directors believes in good faith,
after consultation with the Company's outside legal counsel, that the failure to
engage in such negotiations or discussions, provide such information, so
withhold, withdraw, modify, change or fail to make its Recommendations, so
approve, endorse or recommend such Acquisition Proposal or release or fail to
enforce such "standstill" or similar agreement is inconsistent with the
fiduciary duties of the Board of Directors of the Company under applicable law;
(v) at or prior to furnishing any such nonpublic information to, entering into
discussions or negotiations with, or releasing from a "standstill" or similar
agreement, or failing to enforce such a provision against, any Person, the
Company gives Parent written notice of the identity of such Person and of the
Company's intention to furnish nonpublic information to, enter into discussions
or negotiations with, or release from a "standstill" or similar agreement or
fail to enforce such a provision against, such Person, and the Company receives
from such Person an executed confidentiality agreement (including "standstill"
provisions) not substantially less favorable to the Company than the
Confidentiality Agreement; and (vi) at the time of or prior to furnishing any
such nonpublic information to such Person, the Company furnishes such nonpublic
information to Parent (to the extent such nonpublic information has not been
previously furnished by the Company to Parent), then the Company may furnish
information with respect to the Company and its Subsidiaries to such Person,
participate with such Person in negotiations regarding such Acquisition
Proposal, enter into discussions or negotiations with, or release from a
"standstill" or similar agreement or fail to enforce such a provision against,
such Person, withhold, withdraw, modify or change in a manner adverse to Parent,
or fail to make, its Recommendations, or approve, endorse or recommend such
Acquisition Proposal, as the case may be.

     The Company shall immediately cease and cause to be terminated any existing
discussions with any Person that relate to any Acquisition Proposal.

     The Company shall promptly (and in any event within one (1) business day)
after receipt of any Acquisition Proposal provide Parent with a copy of any
written Acquisition Proposal and the name of the Person making such Acquisition
Proposal and a written statement with respect to any non-written Acquisition
Proposal received, which statement shall include the identity of the Person
making the Acquisition Proposal and the terms thereof. The Company shall
promptly (and in any event within one (1) business day) advise Parent of any
material modification or proposed modification thereto.

     For purposes of this Agreement, "Acquisition Proposal" means any offer or
proposal for a merger, consolidation, recapitalization, liquidation or other
business combination involving the Company or the acquisition or purchase of 15%
or more of any class of equity securities of the Company, or any tender offer
(including self-tenders) or exchange offer that if consummated would result in
any Person beneficially owning 15% or more of any class of any equity securities
of the Company, or any transaction involving the sale, lease, license or other
disposition (by sale, merger or otherwise) of 15% or more of the book or market
value of assets (including, without limitation, securities of any Subsidiary of
the Company) of the Company and its Subsidiaries, taken as a whole; provided,
however, that for purposes of Section 7.3(a)(ii) hereof, all references in this
sentence to "15%" shall be deemed to be replaced with references to "40%." As
used herein, a "Superior Proposal" shall mean an unsolicited, bona fide written
proposal made by a third party involving the purchase by such third party of a
majority of the outstanding Company Securities or 50% or more of the book or
market value of the assets (including, without limitation, securities of any
Subsidiary of the Company) of the Company and its Subsidiaries taken as a whole
which the Company's Board of Directors believes in good faith, after
consultation with the Company's financial advisor, (i) is reasonably likely to
result in a transaction providing greater benefits to the Company's stockholders
than those provided pursuant to this Agreement and (ii) if applicable, is
reasonably capable of being financed by the Person making such Acquisition
Proposal. Nothing contained in this Agreement shall prohibit the Company or the
Company's Board of Directors from taking and disclosing to the Company's
stockholders a position with respect to a tender or exchange offer by a third
party pursuant to Rules 14d-9 and 14e-2(a) promulgated under the Exchange Act or
from making any disclosure required by applicable law; provided, however, that
unless the conditions set forth in clauses (i) through (vi) of the proviso to
the first sentence of this Section 5.4 are satisfied, the Company's Board of
Directors may not withhold, withdraw, modify or change in a manner adverse to
Parent, or fail to make,

                                       A-27
   169

any of its Recommendations in connection with, or approve, endorse or recommend,
any Acquisition Proposal. The Company also will promptly request each Person
that has executed, on or after January 1, 2000, a confidentiality agreement in
connection with its consideration of an Acquisition Proposal or equity
investment to return all confidential information heretofore furnished to such
Person by or on behalf of the Company or any of its Subsidiaries.

     SECTION 5.5  Director and Officer Liability.

     (a) Parent and the Company agree that all rights to indemnification and all
limitations on liability existing in favor of any Indemnitee (as defined in
Section 5.5(b) hereof) as provided in the Certificate of Incorporation or Bylaws
of the Company or an agreement between an Indemnitee and the Company or a
Subsidiary of the Company as in effect as of the date hereof shall survive the
Merger and continue in full force and effect in accordance with its terms.

     (b) After the Effective Time, Parent shall cause the Surviving Corporation
to indemnify and hold harmless the individuals who on or prior to the Effective
Time were officers or directors of the Company and any of its Subsidiaries (the
"Indemnitees") to the same extent as set forth in subsection (a) above.

     (c) For six (6) years after the Effective Time, the Surviving Corporation
shall provide officers' and directors' liability insurance in respect of acts or
omissions occurring prior to the Effective Time covering each person currently
covered by the Company's officers' and directors' liability insurance policy on
terms with respect to coverage and amount at least as favorable as those of such
policy in effect on the date hereof; provided, however, that in no event shall
the Surviving Corporation be required to expend more than an amount per year
equal to the lesser of $450,000 or 200% of current annual premiums paid by the
Company for such insurance (the "Maximum Amount") to maintain or procure
insurance coverage pursuant hereto; provided, further, that if the amount of the
annual premiums necessary to maintain or procure such insurance coverage exceeds
the Maximum Amount, the Surviving Corporation shall maintain or procure, for
such six-year period, the most advantageous policies of directors' and officers'
insurance obtainable for an annual premium equal to the Maximum Amount.

     (d) The obligations of Parent and the Surviving Corporation under this
Section 5.5 shall not be terminated or modified in such a manner as to adversely
affect any Indemnitee to whom this Section 5.5 applies without the consent of
such affected Indemnitee (it being expressly agreed that the Indemnitees to whom
this Section 5.5 applies shall be third party beneficiaries of this Section
5.5).

     (e) In the event Parent or the Surviving Corporation or any of their
respective successors or assigns (i) consolidates with or merges into any other
Person and shall not be the continuing or surviving corporation or entity in
such consolidation or merger or (ii) transfers all or substantially all of its
properties and assets to any Person, then, and in each case, proper provision
shall be made so that the successors and assigns of Parent or the Surviving
Corporation, as the case may be, honor the indemnification obligations set forth
in this Section 5.5.

     SECTION 5.6  Commercially Reasonable Efforts. Upon the terms and subject to
the conditions of this Agreement, each party hereto shall use commercially
reasonable efforts to take, or cause to be taken, all actions and to do, or
cause to be done, all things necessary, proper or advisable under applicable
laws and regulations to consummate the transactions contemplated by this
Agreement.

     SECTION 5.7  Certain Filings.

     (a) Each party hereto shall file with the Department of Justice and the
Federal Trade Commission a Pre-Merger Notification and Report Form pursuant to
the HSR Act in respect of the transactions contemplated hereby as soon as
practicable (and each party hereto will use its commercially reasonable efforts
to cause such filings to be made within five (5) business days after the date of
this Agreement), and each party will use commercially reasonable efforts to take
or cause to be taken all actions necessary, including to promptly and fully
comply with any requests for information from regulatory Governmental Entities,
to obtain any clearance, waiver, approval or authorization relating to the HSR
Act that is necessary to enable the parties to consummate the transactions
contemplated by this Agreement. Without

                                       A-28
   170

limiting the provisions of this Section 5.7, each party hereto shall use
commercially reasonable efforts to promptly make the filings required to be made
by it with all foreign Governmental Entities in any jurisdiction in which the
parties believe it is necessary or advisable.

     (b) The Company and Parent shall each use commercially reasonable efforts
to resolve such objections, if any, as may be asserted with respect to the Offer
or the Merger or any other transaction contemplated by this Agreement under any
Antitrust Law (as defined in Section 5.7(d)). If any administrative, judicial or
legislative action or proceeding is instituted (or threatened to be instituted)
challenging the Offer or the Merger or any other transaction contemplated by
this Agreement as violative of any Antitrust Law, the Company and Parent shall
each cooperate to contest and resist any such action or proceeding, and to have
vacated, lifted, reversed or overturned any decree, judgment, injunction or
other order (whether temporary, preliminary or permanent) that is in effect and
that restricts, prevents or prohibits consummation of the Offer or the Merger or
any other transaction contemplated by this Agreement, including, without
limitation, by pursuing all reasonable avenues of administrative and judicial
appeal. Notwithstanding anything to the contrary in this Agreement, none of
Parent, any of Parent's Subsidiaries or the Surviving Corporation shall be
required (and the Company shall not, without the prior written consent of
Parent, agree, but shall if so directed by Parent, agree) to hold separate or
divest any of their respective assets or operations or enter into any consent
decree or licensing or other arrangement with respect to any of their assets or
operations.

     (c) Each of the Company and Parent shall promptly inform the other party of
any material communication received by such party from the Federal Trade
Commission, the Antitrust Division of the Department of Justice or any other
governmental or regulatory authority regarding any of the transactions
contemplated hereby.

     (d) "Antitrust Law" means the Sherman Antitrust Act, as amended, the
Clayton Antitrust Act, as amended, and all other federal, state and foreign
statutes, rules, regulations, orders, decrees, administrative and judicial
doctrines, and other laws that are designed or intended to prohibit, restrict or
regulate competition or actions having the purpose or effect of monopolization
or restraint of trade.

     SECTION 5.8  Public Announcements. Neither the Company, Parent nor any of
their respective affiliates shall issue or cause the publication of any press
release or other public announcement with respect to the Offer or the Merger,
this Agreement or the other transactions contemplated hereby without the prior
written consent of the other party, except as may be required by law or by any
listing agreement with, or the policies of, a national securities exchange in
which circumstance reasonable efforts to consult will still be required to the
extent practicable.

     SECTION 5.9  Further Assurances. At and after the Effective Time, the
officers and directors of the Surviving Corporation will be authorized to
execute and deliver, in the name and on behalf of the Company, any deeds, bills
of sale, assignments or assurances and to take and do, in the name and on behalf
of the Company, any other actions to vest, perfect or confirm of record or
otherwise in the Surviving Corporation any and all right, title and interest in,
to and under any of the rights, properties or assets of the Company acquired or
to be acquired by the Surviving Corporation, as a result of, or in connection
with, the Merger.

     SECTION 5.10  Employee Matters.

     (a) From and for a period of one year following the date of Closing, Parent
shall, at its election, either (i) continue (or cause Parent's Subsidiaries to
continue) any Plans to which the Company and/or any of its Subsidiaries is a
party, as such Plans are in effect on the date hereof (the "Company Plans"), or
(ii) arrange for each participant in any Company Plans who become employees of
Parent or any of its Subsidiaries ("Company Participants") to be eligible to
participate in any similar plans or programs of Parent on terms no less
favorable than those offered to similarly situated employees of Parent. On and
after the date of Closing, employees of the Company and any of its Subsidiaries
who become and remain employees of Parent or any of its Subsidiaries shall be
treated no less favorably than similarly situated

                                       A-29
   171

employees of Parent or any of its Subsidiaries with respect to compensation,
employee benefits and terms and conditions of employment.

     (b) No later than one year from the date of Closing, Parent shall, or shall
cause Parent's Subsidiaries to, arrange for all Company Participants not then
participating to become eligible to be participants in all employee benefit
plans of Parent on terms no less favorable than those offered to similarly
situated employees of Parent.

     (c) To the extent service is relevant for purposes of eligibility,
participation or vesting under any employee benefit plan, program or arrangement
established or maintained by Parent or its Subsidiaries for the benefit of
employees of the Surviving Corporation or its Subsidiaries, or for benefit
accrual (other than under any defined benefits pension plan and other than where
it would result in a duplication of benefits), then, to extent permitted by law
and except as set forth on Schedule 5.10 of the Parent Disclosure Schedule, the
employees of the Surviving Corporation and its Subsidiaries shall be credited
for service accrued prior to the date of Closing with the Company or its
Subsidiaries, and with respect to any welfare benefit plans to which such
employee may become eligible, Parent and its Subsidiaries shall cause such plans
to provide credit for the year of Closing for documented co-payments,
deductibles and maximum out-of-pocket payments by such employees and shall, to
extent permitted by law, waive all pre-existing condition exclusions and waiting
periods, other than limitations or waiting periods that had not been satisfied,
under any welfare plans maintained by the Company and its Subsidiaries prior to
the date of Closing.

     SECTION 5.11  Tax-Free Reorganization Treatment. Prior to and after the
Appointment Time and through the Effective Time, each of Parent and the Company
shall take all reasonable actions necessary to cause the Transaction to qualify
as a reorganization under the provisions of Section 368(a) of the Code and to
obtain the opinions of counsel referred to in Annex I hereto, and neither party
will take any action inconsistent therewith. Each of the Company and Parent
shall provide customary tax representation letters prior to the Appointment
Time.

     SECTION 5.12  Blue Sky Permits. Parent shall use commercially reasonable
efforts to obtain, prior to the effective date of the Registration Statement,
all necessary state securities laws or "blue sky" permits and approvals required
to carry out the transactions contemplated by this Agreement, the Offer and the
Merger, and will pay all expenses incident thereto, provided, however, that
Parent shall not be required (a) to qualify to do business as a foreign
corporation in any jurisdiction in which it is not now qualified or (b) to file
a general consent to service of process in any jurisdiction.

     SECTION 5.13  Listing. Parent shall use commercially reasonable efforts to
cause the Parent Shares to be issued in the Merger or upon exercise of Assumed
Options to be listed on the NYSE, subject to notice of official issuance
thereof, prior to the Closing Date.

     SECTION 5.14  State Takeover Laws. If any "fair price," "business
combination" or "control share acquisition" statute or other similar statute or
regulation is or may become applicable to the Offer, the Merger, or the
Stockholder Agreements, the Company and Parent shall each take such actions as
are necessary so that the transactions contemplated by this Agreement may be
consummated as promptly as practicable on the terms contemplated hereby and
otherwise act to eliminate or minimize the effects of any such statute or
regulation on the Offer, the Merger and the Stockholder Agreements.

     SECTION 5.15  Certain Notifications. Between the date hereof and the
Effective Time, each party shall promptly notify the other party hereto in
writing after becoming aware of the occurrence of any event which will, or is
reasonably likely to, result in the failure to satisfy any of the conditions
specified in Annex I hereto or Article VI, as applicable.

     SECTION 5.16  Voting of Shares. Parent and Merger Sub agree to vote all
shares of Company Common Stock acquired in the Offer or otherwise beneficially
owned by them or any of their Subsidiaries as of the applicable record date in
favor of adoption of this Agreement at the Company Stockholder Meeting.

                                       A-30
   172

     SECTION 5.17  Action by Board of Directors. If the Company delivers the
Section 16 Information (as defined in this Section 5.17) to Parent at least 10
days prior to the Effective Time, then, prior to the Effective Time, the Board
of Directors of Parent, or an appropriate committee of non-employee directors
thereof, shall adopt a resolution consistent with the interpretative guidance of
the SEC so that (i) the assumption of the Company Options held by Company
Insiders (as defined hereinafter) in the Merger, and (ii) the receipt by Company
Insiders of Parent Common Stock in exchange for Company Common Stock pursuant to
the Merger, shall in each case be an exempt transaction for purposes of Section
16 of the Exchange Act. For purposes of this Section 5.17, (1) "Company Insider"
shall mean any officer or director of the Company who may become a covered
person of Parent for purposes of Section 16 of the Exchange Act and (2) "Section
16 Information" shall mean the following information for each Company Insider:
(A) the number of shares of Company Common Stock held by such individual and
expected to be exchanged for shares of Parent Common Stock in the Merger; and
(B) the number of Company Options held by such individual and expected to be
converted into options to purchase shares of Parent Common Stock in connection
with the Merger.

     SECTION 5.18  Form S-8. Parent agrees to file a registration statement on
Form S-8 for the shares of Parent Common Stock issuable with respect to the
Assumed Options as soon as is reasonably practicable following the Effective
Time, but in no event later than five (5) business days following the Effective
Time. Parent shall use its commercially reasonable efforts to maintain the
effectiveness of such registration statement (and maintain the current status of
the prospectus contained therein) for so long as such Assumed Options remain
outstanding.

     SECTION 5.19  Comfort Letter. The Company shall use all reasonable efforts
to cause to be delivered to Parent a letter of the Company's independent
accountants, dated no more than two business days before the date on which the
Registration Statement becomes effective (and reasonably satisfactory in form
and substance to Parent), that is customary in scope and substance for "comfort
letters" delivered by independent public accountants in connection with
registration statements similar to the Registration Statement.

                                   ARTICLE VI

                            CONDITIONS TO THE MERGER

     SECTION 6.1  Conditions to Each Party's Obligations. The respective
obligations of the Company, Parent and Merger Sub to consummate the Merger are
subject to the satisfaction or, to the extent permitted by applicable law, the
waiver on or prior to the Effective Time of each of the following conditions:

          (a) If required by the DGCL, this Agreement shall have been adopted
     and the Merger approved by the stockholders of the Company;

          (b) Merger Sub shall have accepted for exchange and exchanged all of
     the shares of Company Common Stock tendered pursuant to the Offer;

          (c) No provision of any applicable law or regulation and no judgment,
     injunction, order or decree shall prohibit the consummation of the Merger
     or the other transactions contemplated by this Agreement; and

          (d) The Registration Statement or the Post-Effective Amendment, as the
     case may be, shall have become effective under the Securities Act and shall
     not be the subject of any stop order or proceedings seeking a stop order,
     and any material "blue sky" and other state securities laws applicable to
     the registration and qualification of the Company Common Stock shall have
     been complied with.

                                  ARTICLE VII

                                  TERMINATION

     SECTION 7.1  Termination. Notwithstanding anything herein to the contrary,
this Agreement may be terminated and the transactions contemplated by this
Agreement may be abandoned:

          (a) by the mutual written consent of the Company and Parent;

          (b) at any time prior to the Effective Time, by either the Company or
     Parent, if:

             (i) the Offer shall have expired or been terminated in accordance
        with the terms of this Agreement without Parent or Merger Sub having
        accepted for exchange any shares of Company Common Stock pursuant to the
        Offer; provided, however, that the right to terminate this Agreement
        under this Section 7.1(b)(i) shall not be available to any party whose
        action or failure to act has been a principal cause of the expiration or
        termination of the Offer without shares of Company Common Stock having
        been accepted for exchange thereunder if such action or failure to act
        constitutes a breach of this Agreement;

             (ii) the Offer has not been consummated on or before September 30,
        2001 (the "Outside Date"); provided, however, that the right to
        terminate this Agreement under this Section 7.1(b)(ii) shall not be
        available to any party whose action or failure to act has been a
        principal cause of the failure of the Offer to have been consummated on
        or before such date if such action or failure to act constitutes a
        breach of this Agreement; or

             (iii) there shall be any applicable law or regulation that makes
        consummation of the Offer or the Merger illegal or otherwise prohibited
        or any judgment, injunction, order or decree of any Governmental Entity

          (c) by Parent if, prior to the Appointment Time, (i) the Board of
     Directors of the Company shall have withdrawn or modified or amended in any
     respect adverse to Parent any of its Recommendations or shall otherwise
     have made a disclosure to stockholders of the Company or a public
     announcement that makes it reasonably apparent that, absent the
     restrictions of Section 5.4 of this Agreement, the Board of Directors of
     the Company would so withdraw, modify or amend any of its Recommendations,
     (ii) the Board of Directors of the Company shall have recommended to the
     stockholders of the Company any Acquisition Proposal or shall have resolved
     or announced an intention to do so, (iii) a tender offer or exchange offer
     for 15% or more of the outstanding shares of Company Common Stock (other

     in clause (ii) of this Section 7.1(d)), to enter into a definitive
     acquisition agreement providing for the consummation of a Superior Proposal
     provided, that: (i) the Company is not in breach of its obligations under
     Section 5.4 hereof in connection with such Superior Proposal, (ii) the
     Company shall have notified Parent in writing that the Company has received
     a Superior Proposal and intends to enter into a definitive acquisition
     agreement providing for the consummation of such Superior Proposal,
     attaching the most current version of such agreement to such notice, and
     (iii) Parent shall not have made, within five (5) business days after
     receipt of the Company's written notice of its intention to enter into a
     definitive acquisition agreement providing for the consummation of a
     Superior Proposal, an offer from Parent that the Board of Directors of the

                                       A-32
   174

     Company determines in good faith, after consultation with its financial
     advisor and its outside legal counsel, provides greater benefits to the
     Company's stockholders than such Superior Proposal;

          (e) by the Company, at any time prior to the Appointment Time, upon a
     material breach of any covenant or agreement on the part of Parent set
     forth in this Agreement, or if any representation or warranty of Parent
     shall have been untrue or inaccurate when made or shall have become untrue
     or inaccurate such that, in the aggregate, in the case of such
     representations and warranties, such untruths or inaccuracies would
     reasonably be expected to have a Parent Material Adverse Effect; provided,
     however, that if such untruth or inaccuracy in Parent's representations and
     warranties or breach by Parent is curable by Parent through exercise of
     commercially reasonable efforts, then the Company may not terminate this
     Agreement pursuant to this Section 7.1(e) until the earlier of (i) the
     expiration of a thirty (30)-day period after delivery of written notice
     from the Company to Parent of such untruth or inaccuracy or breach, or (ii)
     the date on which Parent ceases to exercise commercially reasonable efforts
     to cure such untruth or inaccuracy or breach (it being understood that the
     Company may not terminate this Agreement pursuant to this Section 7.1(e) if
     such untruth or inaccuracy or breach by Parent is cured during such
     thirty-day period); or

          (f) by Parent, at any time prior to the Appointment Time, upon a
     breach of any covenant or agreement on the part of the Company set forth in
     this Agreement, or if any representation or warranty of the Company shall
     have been untrue or inaccurate when made or shall have become untrue or
     inaccurate such that Merger Sub would not be required to accept for
     exchange any shares of Company Common Stock tendered pursuant to the Offer
     by virtue of Sections (b), (c) or (d) of Annex I hereto if the expiration
     of the Offer occurred on the date the breach, untruth or inaccuracy is
     communicated in writing to the Company by Parent; provided, however, that
     if such untruth or inaccuracy in the Company's representations and
     warranties or breach by the Company is curable by the Company through
     exercise of commercially reasonable efforts, then Parent may not terminate
     this Agreement pursuant to this Section 7.1(f) until the earlier of (i) the
     expiration of a thirty (30) day period after delivery of written notice
     from Parent to the Company of such untruth or inaccuracy or breach, or (ii)
     the date on which the Company ceases to exercise commercially reasonable
     efforts to cure such untruth or inaccuracy or breach (it being understood
     that Parent may not terminate this Agreement pursuant to this Section
     7.1(f) if such untruth or inaccuracy or breach by the Company is cured
     during such thirty-day period).

     The party desiring to terminate this Agreement shall give written notice of
such termination to the other party.

     SECTION 7.2  Effect of Termination. Except for any willful breach of this
Agreement by any party hereto (which willful breach and liability therefor shall
not be affected by the termination of this Agreement or the payment of any
Termination Fee (as defined in Section 7.3(a) hereof)), if this Agreement is
terminated pursuant to Section 7.1 hereof, then this Agreement shall become void
and of no effect with no liability on the part of any party hereto; provided,
however, that notwithstanding such termination the agreements contained in
Sections 7.2, 7.3 and 8.7 hereof and, subject to Section 8.10, the proviso to
Section 5.3 hereof shall survive the termination hereof.

     SECTION 8.6  Specific Performance. The parties acknowledge and agree that
any breach of the terms of this Agreement would give rise to irreparable harm
for which money damages would not be an adequate remedy and accordingly the

the transactions contemplated herein are not affected in any manner materially
adverse to any party hereto. Upon such determination that any term or other
provision is invalid, illegal or incapable of being enforced, the parties hereto
shall negotiate in good faith to modify this Agreement so as to effect the
original intent of the parties as closely as possible in a mutually acceptable
manner.

Exhibit and the Schedules hereto, constitutes the entire agreement among the
parties hereto with respect to the subject matter hereof and supersedes all
other prior agreements or understandings, both written and oral, among the
parties or any of them with respect to the subject matter hereof; provided,
however, that Sections 1 through 7, Sections 9 through 13 and the third
paragraph of Section 8 of the Confidentiality Agreement shall not be superseded
and shall remain in full force and effect (it being understood that the first
two paragraphs of Section 8 of the Confidentiality Agreement, and the
"standstill" provisions contained therein, shall be deemed to have terminated as
of the date of this Agreement and shall be of no further force or effect);
provided, however, that the first two (2) paragraphs of Section 8 of the
Confidentiality Agreement shall again become operative in accordance with their
terms upon the termination of this Agreement (other than (i) in the case of such
a termination of this Agreement pursuant to Section 7.1(c), Section 7.1(d) or
Section 7.1(f) or under circumstances pursuant to which the Termination Fee may
become payable pursuant to Section 7.3(a)(ii) and (ii) under circumstances
pursuant to which such provisions would have terminated by their terms if such
provisions had been operative during the period between the date hereof and such
termination of this Agreement).

     SECTION 8.11  Counterparts; Effectiveness. This Agreement may be signed in
any number of counterparts, each of which shall be deemed an original, with the
same effect as if the signatures thereto and hereto were upon the same

have received counterparts hereof signed by all of the other parties hereto.

     SECTION 8.12  Rules of Construction. The parties hereto agree that they
have been represented by counsel during the negotiation and execution of this
Agreement and, therefore, waive the application of any law, regulation, holding
or rule of construction providing that ambiguities in an agreement or other
document will be construed against the party drafting such agreement or
document.

arising out of or relating to this Agreement shall be heard and determined
exclusively in any Delaware state or federal court sitting in Newcastle County.
The parties hereto hereby (a) submit to the exclusive jurisdiction of any state
or federal court sitting in the Newcastle County for the purpose of any action
arising out of or relating to this

                                       A-36
   178

Agreement brought by any party hereto, and (b) irrevocably waive, and agree not
to assert by way of motion, defense or otherwise, in any such action, any claim
that it is not subject personally to the jurisdiction of the above-named courts,
that its property is exempt or immune from attachment or execution, that the
action is brought in an inconvenient forum, that the venue of the action is
improper or that this Agreement or the transactions contemplated hereby may not
be enforced in or by any of the above-named courts.

     SECTION 8.14  Merger Sub Compliance. Whenever this Agreement requires
Merger Sub to take action, such requirement shall be deemed to include an
undertaking on the part of Parent to cause Merger Sub to take such action.

executed by their duly authorized respective officers as of the date first
written above.

     limitations set forth in the preceding clause (A)) as of such particular
     date) (it being understood that, for purposes of determining the accuracy
     of such representations and warranties, (x) all "Company Material Adverse
     Effect" and materiality qualifications and other qualifications based on
     the word "material" contained in such representations and warranties shall
     be disregarded, and (y) any update of or modification to the Company
     Disclosure Schedule made or purported to have been made after the date of
     the Agreement shall be disregarded);

          (d) the representations and warranties of the Company contained in
     Section 3.4 of the Agreement shall not have been true and correct in all
     material respects as of the date of the Agreement;

          (e) except as set forth in the Company Disclosure Schedule, since
     December 31, 2000, there shall not have been a Company Material Adverse
     Effect or the occurrence of any event or the arising of any circumstance
     that would reasonably be expected to have a Company Material Adverse
     Effect; or

          (f) the Merger Agreement shall have been terminated in accordance with
     its terms; which in the good faith judgment of Parent, in any such case,
     makes it inadvisable to proceed with the Offer or the acceptance for
     payment of or payment for the shares of Company Common Stock.

     The foregoing conditions are for the sole benefit of Parent and Merger Sub
and may, subject to the terms of the Agreement, be waived by Parent and Merger
Sub, in whole or in part at any time and from time to time, in the sole
discretion of Parent and Merger Sub. The failure by Parent and Merger Sub at any
time to exercise any of the foregoing rights shall not be deemed a waiver of any
such right and each such right shall be deemed an ongoing right which may be
asserted at any time and from time to time.

     THIS STOCKHOLDER AGREEMENT, dated as of March 26, 2001 (this "Agreement"),
is made and entered into between LSI Logic Corporation, a Delaware corporation
("Parent"), and the undersigned stockholder and/or option holder (the
"Stockholder") of C-Cube Microsystems Inc. (the "Company").

     WHEREAS, as of the date hereof, the Stockholder is the beneficial owner (as
defined in Rule 13d-3 under the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), of outstanding shares common stock of the Company, par value
$0.001 per share ("Company Common Stock"), and shares of Company Common Stock
issuable upon exercise of outstanding options, warrants and other rights to
purchase Company Common Stock, in each case as indicated on the signature page
to this Agreement;

     WHEREAS, Parent and the Company propose to enter into an Agreement and Plan
of Reorganization dated as of even date herewith (the "Merger Agreement"), which
provides for, among other things, an exchange offer (the "Offer") to be made by
Clover Acquisition Corp., a Delaware corporation and wholly-owned subsidiary of
Parent ("Merger Sub"), of shares of Parent common stock for all of the issued
and outstanding Company Common Stock followed by the merger of Merger Sub with
and into the Company upon the terms and subject to the conditions set forth in
the Merger Agreement; capitalized terms used herein but not defined shall have
the meanings ascribed to them in the Merger Agreement; and

     WHEREAS, Parent has requested that the Stockholder (in his, her or its
capacity as such) agree, and, in order to induce Parent to enter into the Merger
Agreement, the Stockholder has agreed to enter into this Agreement;

     NOW, THEREFORE, in consideration of the premises and of the mutual
agreements and covenants set forth herein, and intending to be legally bound
hereby, the parties hereto hereby agree as follows:

                                   ARTICLE 1.

                                VOTING OF SHARES

     1.1 Voting of Shares and Proxy.

     (a) Until the Expiration Date (as defined in Section 5.14 below), at every
meeting of the stockholders of the Company called, and at every adjournment
thereof, and on every action or approval by written consent of the stockholders
of the Company, the Stockholder shall cause the Shares (as defined in Section
1.1(b) below) to be voted: (i) in favor of the adoption and approval of the
Merger Agreement, and in favor of each of the other actions contemplated by the
Merger Agreement and the Proxy and any action required in furtherance thereof;
(ii) against approval of any Acquisition Proposal or any proposal made in
opposition to or in competition with consummation of the Merger and/or the
Offer; and (iii) against any action that could reasonably be expected to delay
or otherwise adversely affect the Merger or the Offer and would constitute a
breach of any covenant of the Company pursuant to the Merger Agreement.

     Prior to the Expiration Date, the Stockholder shall not enter into any
agreement or understanding with any Person to vote or give instructions in any
manner inconsistent with the terms of this Section 1.1.

     (b) "Shares" shall mean: (i) all securities of the Company (including all
shares of Company Common Stock and all options, warrants and other rights to
acquire such securities) beneficially owned by the Stockholder as of the date of
this Agreement; and (ii) all additional securities of the Company (including all
shares of Company Common Stock and all additional options, warrants and other
rights to acquire such securities) of which the Stockholder acquires beneficial
ownership during the period from the date of this Agreement through the
Expiration Date. In the event of a stock dividend or distribution, or any change
in Company Common Stock by reason of any stock dividend, split-up,
recapitalization, combination, exchange of shares or the like, the term "Shares"
shall be deemed to refer to and include the Shares as well as all such stock
dividends and distributions and any securities into which or for which any or
all of the Shares may be changed or exchanged or which are received in such
transaction.

                                       B-1

     1.2 Irrevocable Proxy. Concurrently with the execution of this Agreement,

as Exhibit A (the "Proxy"), which shall be irrevocable to the fullest extent
permissible by law but subject to termination as stated therein, with respect to
the Shares.

     1.3 Agreement to Tender. Unless Parent shall otherwise request, the
Stockholder hereby agrees to tender, or cause to be tendered, pursuant to and in
accordance with the terms of the Offer, the Shares, and agrees that it will not
withdraw or permit the withdrawal of the Shares. Within ten (10) business days
after commencement of the Offer, the Stockholder shall (x) deliver to the
depositary designated in the Offer (i) a letter of transmittal with respect to
the Shares complying with the terms of the Offer, (ii) certificates representing
of the Shares and (iii) all other documents or instruments required to be
delivered pursuant to the terms of the Offer, and/or (y) instruct its broker or
such other Person who is the holder of record of any Shares beneficially owned
by the Stockholder to promptly tender such Shares for exchange in the Offer
pursuant to the terms and conditions of the Offer.

     1.4 Agreement Not to Exercise Appraisal Rights. The Stockholder agrees not
to exercise any rights (including, without limitation, under Section 262 of the
General Corporation Law of the State of Delaware) to demand appraisal of any
Shares which may arise with respect to the Merger.

                                   ARTICLE 2.

                      RESTRICTIONS ON TRANSFERS OF SHARES

     2.1 Restrictions on Transfer of Shares Prior to the Effective Time.

     (a) At all times commencing with the execution of this Agreement and until
the Expiration Date, the Stockholder hereby agrees not to, directly or
indirectly, take any of the following actions, except in accordance with
subsection (b) of this Section 2.1 or as provided in this Agreement and the
Merger Agreement:

          (i) tender any of the Shares or any securities convertible into or
     exchangeable or exercisable for the Shares to any Person;

          (ii) sell, pledge, grant an option with respect to, transfer, assign
     or otherwise dispose of any of the Shares or any securities convertible
     into or exchangeable or exercisable for the Shares or any interest therein,
     or enter into any commitment relating thereto; or

          (iii) deposit, or permit the deposit of, any of the Shares into a
     voting trust or depositary facility or enter into a voting agreement or
     arrangement with respect to any Shares in contravention of the obligations
     of the Stockholder under this Agreement or grant any proxy (other than the
     Proxy) with respect thereto or enter into any commitment relating thereto
     (any transaction referred to in clause (i), (ii) or (iii) is hereinafter
     referred to as a "Transfer").

     (b) Notwithstanding subsection (a) above, the Stockholder may take an
action described in subsection (a) if (i) Parent gives its prior written consent
to such action and (ii) the proposed transferee shall have executed a
counterpart of this Agreement and the Proxy and shall have agreed to hold such
Shares or interest in such Shares subject to all of the terms and provisions of
this Agreement.

   184

                                   ARTICLE 3.

                 REPRESENTATIONS AND WARRANTIES, AND ADDITIONAL
                          COVENANTS OF THE STOCKHOLDER

     The Stockholder hereby represents and warrants and covenants to Parent as
follows:

     3.1 Organization; Authorization.

     (a) If the Stockholder is a corporation or other entity, the Stockholder is
duly organized, validly existing and in good standing under the laws of the
jurisdiction of its incorporation or organization and has the requisite power
and authority and all necessary governmental approvals to own, lease and operate
its properties and to carry on its business as it is now being conducted, except
where the failure to be so organized, existing or in good standing or to have
such power, authority and governmental approvals would not prevent or delay the
performance in any respect by the Stockholder of its obligations under this
Agreement. The Stockholder has full power and authority to make, enter into and
carry out the terms of this Agreement and the Proxy. The execution and delivery
of this Agreement and the Proxy and the consummation of the transactions
contemplated hereby and thereby have been duly authorized by all necessary
corporate action on the part of the Stockholder.

     (b) Each of this Agreement and the Proxy has been duly executed and
delivered by or on behalf of the Stockholder, and (with respect to this
Agreement) assuming its due authorization, execution and delivery by the other
parties hereto, constitutes the legal, valid and binding obligation of the
Stockholder, enforceable against the Stockholder in accordance with its terms,
except as may be limited by the effect of bankruptcy, insolvency (including,
without limitation, all laws relating to fraudulent transfers), conservatorship,
arrangement, moratorium or other laws affecting or relating to the rights of
creditors generally and except as enforcement thereof is subject to general
principals of equity (regardless of whether enforcement is considered in a
proceeding in equity or at law).

     3.2 No Conflict. The execution and delivery of this Agreement and the Proxy
by the Stockholder does not, and the performance of this Agreement and the Proxy
by the Stockholder will not, (i) if the Stockholder is a corporation or other
entity, conflict with or violate the Certificate of Incorporation or By-laws or
other similar constituent documents of the Stockholder, (ii) conflict with or
violate any law, rule, regulation, order, judgment or decree applicable to the
Stockholder or by which it or any of its properties is bound or affected, or
(iii) result in any breach of or constitute a default (or an event that with
notice or lapse of time or both would become a default) under, or give to
another party any rights of termination, amendment, acceleration or cancellation
of, or result in the creation of a lien or encumbrance on any of the property or
assets of the Stockholder, including, without limitation, the Shares, pursuant
to any note, bond, mortgage, indenture, contract, agreement, lease, license,
permit, franchise or other instrument or obligation to which the Stockholder is
a party or by which the Stockholder or any of its properties is bound or
affected, except for any such breaches, defaults or other occurrences that would
not prevent or delay the performance by the Stockholder of its obligations under
this Agreement.

     3.3 Title to Shares. The Stockholder is the registered or beneficial owner
of its Shares free and clear of any lien or encumbrance, proxy or voting
restriction other than pursuant to this Agreement. Such Shares are all the
securities of the Company owned of record or beneficially by the Stockholder on
the date of this Agreement.

     3.4 Reliance by Parent. The Stockholder understands and acknowledges that
Parent is entering into the Merger Agreement in reliance upon the Stockholder's
execution and delivery of this Agreement and the Proxy.

     3.5 Miscellaneous. Except as otherwise provided herein, nothing contained
in this Agreement shall be deemed to vest in Parent any direct or indirect
ownership or incidence of ownership of or with respect to any of the Shares.
Except as otherwise provided herein, all rights, ownership and economic benefits
of and relating to the Shares shall remain and belong to the Stockholder, and
Parent shall not have any authority to manage, direct, superintend, restrict,
regulate, govern, or administer any of the policies or

                                       B-3
   185

operations of the Company or exercise any power or authority to direct the
Stockholder in the voting of any of the Shares, except as otherwise provided
herein, or the performance of the Stockholder's duties or responsibilities as a
stockholder of the Company.

                                   ARTICLE 4.

                    REPRESENTATIONS AND WARRANTIES OF PARENT

standing under the laws of the jurisdiction of its incorporation and has the
requisite power and authority and all necessary governmental approvals to own,
lease and operate its properties and to carry on its business as it is now being

standing or to have such power, authority and governmental approvals would not
prevent or delay the performance in any material respect by Parent of its
obligations under this Agreement. Parent has full power and authority to make,
enter into and carry out the terms of this Agreement. The execution and delivery
of this Agreement and the consummation of the transactions contemplated hereby
have been duly authorized by all necessary corporate action on the part of
Parent.

     (b) This Agreement has been duly executed and delivered by or on behalf of
the Parent and, assuming its due authorization, execution and delivery by the
other parties hereto, constitutes the legal, valid and binding obligation of
Parent, enforceable against Parent in accordance with its terms, except as may
be limited by the effect of bankruptcy, insolvency (including, without
limitation, all laws relating to fraudulent transfers), conservatorship,
arrangement, moratorium or other laws affecting or relating to the rights of
creditors generally and except as enforcement thereof is subject to general
principals of equity (regardless of whether enforcement is considered in a
proceeding in equity or at law).

     4.2 No Conflict. The execution and delivery of this Agreement by Parent
does not, and the performance of this Agreement by Parent will not, (i) conflict
with or violate the Certificate of Incorporation or By-laws of Parent, (ii)
conflict with or violate any law, rule, regulation, order, judgment or decree
applicable to Parent or by which it or any of its properties is bound or
affected, or (iii) result in any breach of or constitute a default (or an event
that with notice or lapse of time or both would become a default) under, or give
to another party any rights of termination, amendment, acceleration or
cancellation of, or result in the creation of a lien or encumbrance on any of
the property or assets of Parent, pursuant to any note, bond, mortgage,
indenture, contract, agreement, lease, license, permit, franchise or other

     5.2 Interpretation.

     (a) Whenever the words "include," "includes" or "including" are used in
this Agreement they shall be deemed to be followed by the words "without
limitation." As used in this Agreement, the term "affiliate" shall have the
meaning set forth in Rule 12b-2 promulgated under the Exchange Act.

     (b) The article and section headings contained in this Agreement are solely
for the purpose of reference, are not part of the agreement of the parties
hereto and shall not in any way affect the meaning or interpretation of this
Agreement.

     5.3 Amendments and Waiver. Any provision of this Agreement may be amended
or waived by the parties hereto if, and only if, such amendment or waiver is in
writing and signed, in the case of an amendment, by the Stockholder and Parent
or, in the case of a waiver, by the party against whom the waiver is to be
effective.

     5.4 Specific Performance; Injunctive Relief. Each of the parties hereto
hereby acknowledges that (i) the representations, warranties, covenants and
restrictions set forth in this Agreement are necessary, fundamental and required
for the protection of Parent and to preserve for Parent the benefits of the
Merger; (ii) such covenants relate to matters which are of a unique character
that gives each such representation, warranty, covenant and restriction a unique
value; and (iii) a breach of any such
                                       B-5
   187

representation, warranty, covenant or restriction, or any other term or
provision of this Agreement, will result in irreparable harm and damages to
Parent which cannot be adequately compensated by a monetary award. Accordingly,
Parent and the Stockholder hereby expressly agree that in addition to all other
remedies available at law or in equity, Parent shall be entitled to the
immediate remedy of specific performance, a temporary and/or permanent
restraining order, preliminary injunction or such other form of injunctive or
equitable relief as may be used by any court of competent jurisdiction to
restrain or enjoin any of the parties hereto from breaching any representations,
warranties, covenants or restrictions set forth in this Agreement, or to
specifically enforce the terms and provisions hereof. The Stockholder further
agrees that neither Parent nor any other Person shall be required to obtain,
furnish or post any bond or similar instrument in connection with or as a
condition to obtaining any remedy referred to in this Section 5.4, and the
Stockholder irrevocably waives any right he may have to require the obtaining,
furnishing or posting of any such bond or similar instrument. If any legal
action or other legal proceeding relating to this Agreement or the enforcement
of any provision of this Agreement is brought against the Stockholder, the
prevailing party shall be entitled to recover reasonable attorneys' fees, costs
and disbursements (in addition to any other relief to which the prevailing party
may be entitled).

     5.5 Successors and Assigns. The provisions of this Agreement shall be
binding upon and inure to the benefit of the parties hereto and their respective
successors and assigns.

     5.6 Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of Delaware (regardless of the laws that
might otherwise govern under applicable principles of conflicts of laws thereof)
as to all matters, including, but not limited to, matters of validity,
construction, effect, performance and remedies.

     5.7  Severability. If any term or other provision of this Agreement is
invalid, illegal or incapable of being enforced by any rule of law, or public
policy, all other conditions and provisions of this Agreement shall nevertheless
remain in full force and effect so long as the economic or legal substance of
the transactions contemplated herein are not affected in any manner materially
adverse to any party hereto. Upon such determination that any term or other
provision is invalid, illegal or incapable of being enforced, the parties hereto
shall negotiate in good faith to modify this Agreement so as to effect the
original intent of the parties as closely as possible in a mutually acceptable
manner.

     5.8  Entire Agreement. This Agreement and the Proxy constitute the entire
agreement among the parties hereto with respect to the subject matter hereof and
supersede all other prior agreements or understandings, both written and oral,
between the parties or any of them with respect to the subject matter hereof and
thereof.

     5.9  Counterparts; Effectiveness. This Agreement may be signed in any
number of counterparts, each of which shall be deemed an original, with the same
effect as if the signatures thereto and hereto were upon the same instrument.
This Agreement shall become effective when each party hereto shall have received
counterparts hereof signed by all of the other parties hereto.

     5.10  Rules of Construction. The parties hereto agree that they have been
represented by counsel during the negotiation and execution of this Agreement
and, therefore, waive the application of any law, regulation, holding or rule of
construction providing that ambiguities in an agreement or other document will
be construed against the party drafting such agreement or document.

     5.11  Submission to Jurisdiction. All actions and proceedings arising out
of or relating to this Agreement shall be heard and determined exclusively in
any Delaware state or federal court sitting in Newcastle County. The parties
hereto hereby (a) submit to the exclusive jurisdiction of any state or federal
court sitting in Newcastle County for the purpose of any action arising out of
or relating to this Agreement brought by any party hereto, and (b) irrevocably
waive, and agree not to assert by way of motion, defense, or otherwise, in any
such action, any claim that it is not subject personally to the jurisdiction of
the above-named courts, that its property is exempt or immune from attachment or
execution, that the action is brought in an inconvenient forum, that the venue
of the action is improper, or

                                       B-6
   188

that this Agreement or the transactions contemplated hereby may not be enforced
in or by any of the above-named courts.

     5.12  Directors and Officers. Notwithstanding any provision of this
Agreement to the contrary, nothing in this Agreement shall limit or restrict the
Stockholder from acting in the Stockholder's capacity as a director or officer
of Company (it being understood that this Agreement shall apply to the
Stockholder solely in the Stockholder's capacity as a stockholder of the
Company) or voting in the Stockholder's sole discretion on any matter other than
those matters referred to in Section 1(a).

     5.13  No Exercise of Options, Warrants or Other Rights. Notwithstanding any
provision of this Agreement to the contrary, nothing in this Agreement shall
require the Stockholder to exercise or convert Shares that do not constitute
outstanding shares of Company Common Stock.

     5.14  Termination. This Agreement and the Proxy, and all obligations of the
parties hereunder and thereunder, shall terminate immediately, without any
further action being required, upon (i) any valid termination of the Merger
Agreement pursuant to its terms and (ii) the Effective Time, whichever first
occurs (the "Expiration Date").

     5.15  Further Assurances. The Stockholder (solely in his or her capacity as
such, but not in any other capacity including as director or officer of the
Company) shall execute and deliver, and cause to be executed and delivered, any
additional certificates, instruments and other documents, and take and cause to
be taken any additional actions, as Parent may deem necessary, in the reasonable
opinion of Parent, to carry out and effectuate the purpose and intent of this
Agreement.

                               IRREVOCABLE PROXY

     The undersigned stockholder of C-Cube Microsystems Inc., a Delaware
corporation (the "Company"), hereby irrevocably (to the fullest extent permitted
by law), but subject to the termination provisions hereof, appoints LSI
Corporation, a Delaware corporation ("Parent"), as the sole and exclusive
attorney and proxy of the undersigned, with full power of substitution and
resubstitution, to vote and exercise all voting and related rights (to the full
extent that the undersigned is entitled to do so) with respect to all of the
shares of the Company that now are or hereafter may be beneficially owned by the
undersigned, and any and all other shares or securities of the Company issued or
issuable in respect thereof on or after the date hereof (collectively, the
"Shares") in accordance with the terms of this Proxy. The outstanding shares of
common stock of the Company owned of record by the undersigned stockholder of
the Company as of the date of this Proxy are listed on the final page of this
Proxy. Upon the undersigned's execution of this Proxy, any and all prior proxies

Shares.

     This Proxy is irrevocable (to the fullest extent permitted by law), subject
to the termination provisions hereof, is coupled with an interest and is granted
pursuant to that certain Stockholder Agreement of even date herewith by and
between and the undersigned stockholder (the "Stockholder Agreement"), and is
granted in consideration of Parent entering into that certain Agreement and Plan
of Reorganization (the "Merger Agreement") among Parent, Clover Acquisition,
Corp., a wholly-owned subsidiary of Parent ("Merger Sub"), and the Company. The
Merger Agreement provides for the acquisition of the Company by Parent pursuant

by the undersigned to act as the undersigned's attorney and proxy to vote the
Shares, and to exercise all voting, consent and similar rights of the
undersigned with respect to the Shares (including, without limitation, the power
to execute and deliver written consents) at every annual, special or adjourned
meeting of stockholders of the Company and in every written consent in lieu of
such meeting: (i) in favor of the adoption and approval of the Merger Agreement,
and in favor of each of the other actions contemplated by the Merger Agreement
and the Proxy and any action required in furtherance thereof; (ii) against
approval of any Acquisition Proposal or any proposal made in opposition to or in
competition with consummation of the Merger and/or the Offer; and (iii) against
any action that could reasonably be expected to delay or otherwise adversely
affect the Merger or the Offer and would constitute a breach of any covenant of
the Company pursuant to the Merger Agreement.

     (b) The attorneys and proxies named above may not exercise this Proxy on
any other matter except as provided above. The undersigned Stockholder may vote
the Shares on all other matters.

     Any obligation of the undersigned hereunder shall be binding upon the
successors and assigns of the undersigned.

     This Proxy is irrevocable (to the fullest extent permitted by law), subject
to the termination provisions hereof.

   191

     This Proxy, and all obligations of the undersigned hereunder, shall
terminate immediately, without any further action being required, upon (i) any
valid termination of the Merger Agreement pursuant to its terms and (ii) the
Effective Time, whichever first occurs.

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS

CERTIFICATE OF INCORPORATION

     Article 10 of the LSI Logic restated certificate of incorporation provides
that, to the fullest extent permitted by Delaware law, as the same now exists or
may hereafter be amended, a director shall not be personally liable to the
corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director. Delaware law provides that directors of a corporation will
not be personally liable for monetary damages for breach of their fiduciary
duties as directors, except for liability:

     - for any breach of their duty of loyalty to the corporation or its
       stockholders;

     - for acts or omissions not in good faith or that involve intentional
       misconduct or a knowing violation of law;

     - for unlawful payments of dividends or unlawful stock repurchases or
       redemption as provided in Section 174 of the Delaware General Corporation
       Law; or

     - for any transaction from which the director derived an improper personal
       benefit.

BYLAWS

     LSI Logic's bylaws provide that its directors, officers and agents shall be
indemnified against expenses including attorneys' fees, judgments, fines and
amounts paid in any settlement that is actually and reasonably incurred in
connection with any proceeding arising out of their status as a director, if the
director, officer or agent acted in good faith and in a manner he or she
reasonably believed to be in or not opposed to the best interests of LSI Logic,
and, with respect to any criminal action or proceeding, had no reasonable cause
to believe their conduct was unlawful.

     LSI Logic has entered into agreements to indemnify its directors and
officers, in addition to the indemnification provided for in its certificate of
incorporation and bylaws. These agreements, among other things, indemnify LSI
Logic's directors and officers for certain expenses, including attorney's fees,
judgments, fines and settlement amounts incurred by any LSI Logic director or
officer in any action or proceeding, including any action by or in the right of
LSI Logic, arising out of any LSI Logic director's or officer's services as a
director or officer of LSI Logic, any subsidiary of LSI Logic or any other
company or enterprise to which the person provides services at the request of
LSI Logic.

MERGER AGREEMENT PROVISIONS RELATING TO INDEMNIFICATION OF C-CUBE DIRECTORS AND
OFFICERS

     The merger agreement provides that all rights to indemnification and all
limitations on liability existing in favor of the individuals who, on or prior
to the completion of the merger were officers or directors of C-Cube or any of
its subsidiaries, as provided in C-Cube's certificate of incorporation or
bylaws, or in an agreement between one of the above parties and C-Cube or a
subsidiary of C-Cube, as in effect as of March 26, 2001, shall survive the
merger and continue in full force and effect in accordance with its terms.

     After the completion of the merger, LSI Logic is required to cause the
surviving corporation in the merger to indemnify and hold harmless the
individuals who on or before the completion of the merger were officers or
directors of C-Cube or any of its subsidiaries to the same extent those
individuals were indemnified and held harmless prior to the completion of the
merger.

     The merger agreement also provides that for six years after the completion
of the merger, the surviving corporation shall provide officers' and directors'
liability insurance in respect of acts or omissions occurring prior to the
completion of the merger, covering each C-Cube officer and director currently

                                       II-1
   194

covered by C-Cube's officers' and directors' liability insurance policy on terms
with respect to coverage and amount at least as favorable as those of the policy
in effect on March 26, 2001. However, the surviving corporation is not required
to expend more than the lesser of $450,000 or 200% of current annual premiums
paid by C-Cube for the insurance each year to maintain or procure the insurance
coverage. In addition, if the amount of the annual premiums necessary to
maintain or procure the insurance coverage exceeds the amount described in the
preceding sentence, the surviving corporation shall maintain or procure, for a
six-year period, the most advantageous policies of directors' and officers'
insurance obtainable for an annual premium equal to the amount described in the
preceding sentence.

     These obligations of LSI Logic and the surviving corporation may not be
terminated or modified in any manner that adversely affects any person to whom
the indemnification rights apply, without the consent of that person.

     In the event that LSI Logic or the surviving corporation or any of their
respective successors or assigns (i) consolidates with or merges into any other
person and is not the continuing or surviving corporation or entity in the
consolidation or merger, or (ii) transfers all or substantially all of its
properties and assets to any person, then, and in each case, proper provision
shall be made so that the successors and assigns of LSI Logic or the surviving
corporation, as the case may be, honor the indemnification obligations described
in the merger agreement.

ITEM 22. UNDERTAKINGS

     (a) The undersigned Registrant hereby undertakes:

          (1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this registration statement:

             (i) To include any prospectus required by Section 10(a)(3) of the
        Securities Act of 1933;

             (ii) To reflect in the prospectus any facts or events arising after
        the effective date of the registration statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the registration statement. Notwithstanding the foregoing, any
        increase or decrease in volume of securities offered (if the total
        dollar value of securities offered would not exceed that which was
        registered) and any deviation from the low or high end of the estimated
        maximum offering range may be reflected in the form of prospectus filed
        with the Commission pursuant to Rule 424(b) if, in the aggregate, the
        changes in volume and price represent no more than 20 percent change in
        the maximum aggregate offering price set forth in the "Calculation of
        Registration Fee" table in the effective registration statement.

             (iii) To include any material information with respect to the plan
        of distribution not previously disclosed in the registration statement
        or any material change to such information in the registration
        statement.

          (2) That, for the purpose of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.

          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.

     (b) The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of
1934) that is incorporated by reference in the registration statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the exchange offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.

     (c) The undersigned Registrant hereby undertakes as follows: that prior to
any public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), such
reoffering prospectus will contain the information called for by the applicable
registration form with respect to reofferings by persons who may be deemed
underwriters, in addition to the information called for by the other Items of
the applicable form.

     (d) The undersigned Registrant hereby undertakes that every prospectus (i)
that is filed pursuant to paragraph 3(a) immediately preceding, or (ii) that
purports to meet the requirements of Section 10(a)(3)

                                       II-3
   196

of the Securities Act of 1933 and is used in connection with an offering of
securities subject to Rule 415, will be filed as a part of an amendment to the
registration statement and will not be used until such amendment is effective,
and that, for purposes of determining any liability under the Securities Act of
1933, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
exchange offering of such securities at that time shall be deemed to be the
initial bona fide offering thereof.

     (e) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

     (f) The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the Prospectus pursuant to
Item 4, 10(b), 11 or 13 of this form, within one business day of receipt of such
request, and to send the incorporated documents by first class mail or other
equally prompt means. This includes information contained in documents filed
subsequent to the effective date of the registration statement through the date
of responding to the request.

     (g) The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.
