ITEM 1.           SECURITY AND ISSUER.

         This statement on Schedule 13D relates to the shares ("Shares") of
common stock, $1.00 par value, of Kerr-McGee Corporation (the "Issuer"). The
principal executive office of the Issuer is located at Kerr-McGee Center,

liability company (the "Reporting Person"). The Reporting Person is a private
money management firm which holds the Shares of the Issuer in various accounts
under its management and control. The principals of the Reporting Person are
Barry Rosenstein and Gary Claar (the "Principals").

         Any disclosures made herein with respect to persons or entities other

after making inquiry to the appropriate party. By virtue of the communications
with the Issuer by representatives of Icahn Partners LP, Icahn Partners Master
Fund LP and High River Limited Partnership (collectively, the "Icahn Group") and
of the Reporting Person, as more fully described in Item 4, the Reporting Person
may be deemed to be a "group" with the Icahn Group for purposes of the Act.
Although the Reporting Person does not affirm that such a group has been formed,
this disclosure is being made to ensure compliance with the Act. The Reporting
Person expressly disclaims beneficial ownership of securities held by any person
or entity other than, to the extent of any pecuniary interest therein, the
various accounts under the Reporting Person's management and control. The
securities reported herein as being beneficially owned by the Reporting Person
do not include any securities held by the Icahn Group or any other person or
entity other than the various accounts under the Reporting Person's management
and control.

         (b) The principal business address of the Reporting Person and the
Principals is 201 Post Street, Suite 1000, San Francisco, California 94108.

         (c) The principal business of the Reporting Person and the Principals
is investing for accounts under their management.

         (d) Neither the Reporting Person nor the Principals has, during the
last five years, been convicted in a criminal proceeding (excluding traffic
violations or similar misdemeanors).

         (e) Neither the Reporting Person nor the Principals has, during the
last five years, been a party to a civil proceeding of a judicial or
administrative body of competent jurisdiction and as a result of such proceeding
was or is subject to a judgment, decree or final order enjoining future
violations of, or prohibiting or mandating activities subject to, federal or
state securities laws or finding any violation with respect to such laws.

------------------------------                             ---------------------

         (f) The Reporting Person is a limited liability company organized in
Delaware. The Principals are citizens of the United States of America.

ITEM 3.           SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

         Of the 4,501,300 Shares reported herein by the Reporting Person,
2,801,100 Shares were acquired at an aggregate purchase price of approximately
$174,730,022.67, and the remaining 1,700,200 Shares represent options to acquire
Shares, which options were acquired at an aggregate purchase price of 
approximately $4,370,809.54. The Shares beneficially owned by the Reporting
Person were acquired with investment funds in accounts under management.

ITEM 4.           PURPOSE OF TRANSACTION.

         The Reporting Person originally acquired Shares for investment in the
ordinary course of business. The Reporting Person believes that the Shares at
current market prices are undervalued and represent an attractive investment
opportunity. On or about February 23, 2004, representatives of the Reporting
Person and the Icahn Group spoke with Luke R. Corbett, Chairman and Chief
Executive Officer of the Issuer, and suggested various actions to be taken by
the Issuer that they believe would enhance stockholder value. These suggestions
were then memorialized in a letter to the Issuer on March 3, 2005, a copy of
which is attached hereto as Exhibit A and incorporated herein by reference.
Pursuant to discussions among the Reporting Person and the Icahn Group, on March
2, 2005 the Icahn Group notified the Issuer that it proposed to nominate Barry
Rosenstein and Carl Icahn for election to the Issuer's board of directors at the
2005 annual meeting of stockholders. Based on the March 2, 2005 deadline for
stockholders to submit proposals, as set forth in the Issuer's bylaws, the
Reporting Person and the Icahn Group believed it necessary to preserve their
right to nominate Messrs. Rosenstein and Icahn as candidates, and to solicit
proxies in favor of these nominees, should the Issuer not take satisfactory
measures in pursuit of stockholder value.

         Neither the Reporting Person nor the Principals has any present plan or
proposal that would relate to or result in any of the matters set forth in
subparagraphs (a)-(j) of Item 4 of Schedule 13D except as set forth herein or
such as would occur upon completion of any of the actions discussed above. The
Reporting Person intends to review its investment in the Issuer on a continuing
basis. Depending on various factors including, without limitation, the Issuer's
financial position and strategic direction, the Issuer's response to the actions
suggested by the Reporting Person and the Icahn Group, price levels of the
Shares, conditions in the securities market and general economic and industry
conditions, the Reporting Person may in the future take such actions with
respect to its investment in the Issuer as it deems appropriate including,
without limitation, purchasing additional Shares or selling some or all of its
Shares, and, alone or with others, pursuing further discussions with the Issuer,
other stockholders and third parties, soliciting proxies in favor of Messrs.
Rosenstein and Icahn and/or otherwise changing its intention with respect to any
and all matters referred to in Item 4.

SECURITY HOLDERS ARE ADVISED TO READ THE PROXY STATEMENT AND OTHER DOCUMENTS
RELATED TO SOLICITATION OF PROXIES BY JANA PARTNERS LLC AND ITS AFFILIATES FROM
THE STOCKHOLDERS OF KERR-MCGEE CORPORATION FOR USE AT ITS ANNUAL MEETING WHEN
AND IF THEY BECOME AVAILABLE, BECAUSE THEY WILL CONTAIN IMPORTANT INFORMATION,
INCLUDING INFORMATION RELATING TO THE PARTICIPANTS IN ANY SUCH PROXY
SOLICITATION. WHEN AND IF COMPLETED, THE PROXY STATEMENT AND SUCH OTHER
DOCUMENTS WILL BE AVAILABLE AT NO CHARGE AT THE SECURITIES AND EXCHANGE
COMMISSION'S WEBSITE AT HTTP://WWW.SEC.GOV, AND A DEFINITIVE PROXY STATEMENT AND
A FORM OF PROXY WILL BE MAILED TO STOCKHOLDERS OF KERR-MCGEE CORPORATION.

ITEM 5.           INTEREST IN SECURITIES OF THE COMPANY.

         (a) The aggregate percentage of Shares reported to be beneficially
owned by the Reporting Person is based upon 151,692,157 Shares outstanding,
which is the total number of Shares outstanding as reported in the Issuer's
Quarterly Report on Form 10-Q for the quarter ended September 30, 2004.

         As of the close of business on March 2, 2005, the Reporting Person may
be deemed to beneficially own 4,501,300 Shares (including options to purchase up
to 1,700,200 Shares), constituting approximately 2.6% of the Shares outstanding.
Upon information and belief, the Icahn Group, as of the close of business on
March 2, 2005, may be deemed to beneficially own 7,106,000 Shares. Accordingly,
the 11,607,300 Shares that may be deemed to be beneficially owned in the
aggregate by the Reporting Person and the Icahn Group, as of the close of
business on March 2, 2005, constitutes approximately 7.65% of the Shares
outstanding.

         (b) The Reporting Person has sole voting and dispositive powers over
the 4,501,300 Shares reported herein (including, if such options are exercised,
the 1,700,200 Shares underlying the options reported herein), which powers are
exercised by the Principals.

         (c) Information concerning transactions in the Shares effected by the
Reporting Persons during the past sixty days is set forth in Exhibit B hereto
and is incorporated herein by reference. Except for 250,000 Shares sold in a
private transaction pursuant to an option that had been issued to and exercised
by the Icahn Group, all of the transactions in Shares listed on Exhibit B hereto
were effected in open market purchases on the New York Stock Exchange through
various brokerage entities. All of the options held, as reported herein, were
acquired in open market purchases as set forth in Item 6.

         (d) No person (other than the Reporting Person) is known to have the
right to receive or the power to direct the receipt of dividends from, or the
proceeds from the sale of, the Shares.

         (e) Not applicable.

ITEM 6.           CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH
                  RESPECT TO SECURITIES OF THE COMPANY.

         As set forth below, the Reporting Person holds, as of March 2, 2005,
options to acquire 1,700,200 Shares, each of which was acquired on the open
market:

VIA FEDERAL EXPRESS AND FACSIMILE 
----------------------------------
Mr. Luke R. Corbett
Chairman and Chief Executive Officer
Kerr-McGee Corporation
123 Robert S. Kerr Avenue
Oklahoma City, Oklahoma 73102

Dear Mr. Corbett:

         As we have previously discussed with you, each of us is a large
shareholder of Kerr-McGee Corporation ("KMG"), beneficially owning, in the
aggregate, approximately 11.6 million shares or approximately 7.6% of the
outstanding shares of KMG's common stock. Entities affiliated with Carl Icahn
recently proposed Carl Icahn and Barry Rosenstein, managing partner of Jana
Partners (a $3 billion hedge fund), as nominees for KMG's board of directors at
the upcoming annual meeting. This action was taken in order to help ensure that
KMG is focused on maximizing shareholder value. While management's recent
announcement of its intention to review strategic alternatives for its chemicals
business is a positive first step, we feel this action does not go far enough
toward maximizing the value of KMG's common stock.

         A great opportunity exists today for shareholders of KMG. Never before
has there been such a disconnect between the stock market valuation of publicly
traded E&P companies such as KMG on a per barrel of oil equivalent ("boe") of
proved reserves basis and the value at which oil and gas futures are trading in
the commodity markets. We believe that this spread can be captured by KMG by
selling today a portion of its production for delivery over the next five years
and utilizing the proceeds from such a sale, today, to immediately repurchase
stock. We believe that if KMG were to follow the plan outlined below (and
detailed in the attached schedule), KMG's share price would increase
significantly. The plan would require KMG to take the following steps:

     1.   Sell the chemical business;

     2.   Enter into a transaction to monetize forward production and capitalize
          on today's





---------------------------                                 -------------------

     3.   high price of oil and gas, low interest rate environment and increased
          commodity market liquidity; and

     4.   Utilize the proceeds from the chemical business sale and the forward
          sale of a portion of KMG's future oil and gas production to buy back
          shares.

         At KMG's current market price of $78.99 per share (as of the close of
the market on March 2, 2005), and pro-forma for the sale of its chemicals
business for $1.7 billion (the mid-point of the range projected on KMG's January
26, 2005 fourth quarter conference call), KMG is trading at approximately $11.80
per boe of proved in the ground reserves. To monetize the current discount in
KMG's stock market valuation versus the commodity market valuation for oil and
gas, we recommend that KMG immediately execute a Volumetric Production Payment
transaction ("VPP") for 50 million boe's of proved producing reserves per year
over each of the next five years (i.e., 250 million boe's of production total,
or approximately 32% of KMG's total proved producing reserves), constituting
approximately 37% of KMG's projected 2005 production.

         Based on the current forward curve for oil and gas, the low interest
rate environment and increased liquidity in the commodity markets, we believe
(as a result of discussions with commodity trading firms) that KMG could realize
proceeds of between $35 and $38 per boe sold forward through a VPP transaction.
As such, KMG could raise a total of approximately $8.75 BILLION OF CASH
(assuming the VPP transaction at $35 per boe), or approximately 60% of its
enterprise value (excluding KMG's chemicals business), by selling only
approximately 21% of its total proved reserves. After raising the proceeds
described above (including proceeds from the sale of the chemicals business),
KMG should repurchase up to approximately 116 million shares of its stock at $90
per share. Following such a transaction, KMG would still have approximately 950
million boe of proved reserves, approximately 56% of which would be proved
developed reserves and approximately 44% would be proved undeveloped reserves.

         Assuming that KMG would trade at its current value of $11.80 per boe of
proved reserves (excluding the chemical business), the pro forma share price
following the proposed transactions would be $111 per share. Historically, we
believe investors have penalized KMG's share price due to what we perceive as
poor results achieved in exploration, drilling and use of free cash flow.
However, after giving effect to the proposed VPP transaction and the sale of the
chemicals business, we believe that the public market valuation for KMG's
remaining reserves could increase to be more in line with the reserve valuations
attributed to its comparable companies (see attached schedule). If this were to
occur, KMG could trade at $132 per share. Obviously, there can be no assurance
that KMG common stock will trade within the $111 to $132 range, even if all of
these transactions are undertaken and completed.

         We would like to discuss this recommendation with you at your earliest

convenience since we feel it is important to move quickly while the opportunity
exists.
