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

To Our Fellow Kerr-McGee Stockholders:

         This Proxy Statement and the accompanying GOLD proxy card are being
furnished to stockholders ("Stockholders") of Kerr-McGee Corporation
("Kerr-McGee") in connection with the solicitation of proxies by Carl C. Icahn,
Barry S. Rosenstein and certain of their affiliates and associates, to be used
at the 2005 Annual Meeting of Stockholders of Kerr-McGee which is scheduled to
be held at 9:00 a.m. on Tuesday, May 10, 2005, in the Robert S. Kerr Auditorium,
Kerr-McGee Center, 123 Robert S. Kerr Avenue, Oklahoma City, Oklahoma, and at
any adjournments, postponements or continuations thereof (the "Annual Meeting").
This Proxy Statement and the GOLD proxy card are first being furnished to
Stockholders on or about April __, 2005.

         At the Annual Meeting, the Participants (as hereinafter defined) will
seek to elect to the Board of Directors of Kerr-McGee a slate of two nominees,
comprised of Carl C. Icahn and Barry S. Rosenstein. Each of the nominees (each a
"Nominee" and, collectively, the "Nominees") has consented, if elected, to serve
as a director.

         Subject to their fiduciary duties to Stockholders, the Nominees will,
if elected, attempt to convince Kerr-McGee's Board of Directors to take actions
(such as those previously proposed by the Nominees) to enhance Stockholder
value. Specifically, the Nominees will advocate that Kerr-McGee attempt to take
advantage of the spread between the valuation that the stock market currently
places on Kerr-McGee based on its proved reserves and the higher value at which
oil and gas futures are trading in the commodity markets.

PLEASE NOTE THAT WE CANNOT ASSURE YOU THAT WE WILL BE ABLE TO NOMINATE DIRECTORS
AT THE ANNUAL MEETING. KERR-MCGEE HAS FILED A LAWSUIT SEEKING A DECLARATION THAT
THE NOMINATION OF THE NOMINEES FOR ELECTION AS DIRECTORS AT THE ANNUAL MEETING
IS INVALID BECAUSE, ACCORDING TO KERR-MCGEE, WE FAILED TO COMPLY WITH ITS
ADVANCE NOTICE BYLAW. ALTHOUGH WE BELIEVE KERR-MCGEE'S CLAIMS HAVE ABSOLUTELY NO
MERIT, WE CANNOT PREDICT THE OUTCOME OF LITIGATION. THAT WILL BE DECIDED BY A
FEDERAL COURT IN OKLAHOMA. STOCKHOLDERS WHO SUBMIT GOLD PROXY CARDS SHOULD BE 
AWARE THAT THEIR SHARES MAY


                                       3


NOT BE VOTED IN THE ELECTION OF DIRECTORS IF KERR-MCGEE IS SUCCESSFUL IN THE
LITIGATION.

          DON'T LET KERR-MCGEE PREVENT YOU FROM CHOOSING FOR YOURSELF!

         Kerr-McGee has filed a lawsuit in federal court in Oklahoma against the
Nominees and certain of their respective affiliates, seeking, among other
things, a court order declaring that the nomination of the Nominees at the
Annual Meeting is invalid because of a purported failure to comply with
Kerr-McGee's advanced notice bylaw. Thus, instead of debating on the merits and
permitting Stockholders to choose directors for themselves, Kerr-McGee is
attempting to prevent the Nominees from being nominated at all - thus leaving
you with NO CHOICE but the existing directors. If the court should grant the
relief requested by Kerr-McGee, the Nominees will not be able to be nominated at
the Annual Meeting and you will not be permitted to cast your vote for the
Nominees. Because only a plurality vote (as opposed to a majority) is required
to elect Kerr-McGee directors, if Kerr-McGee succeeds in having its existing
directors run unopposed they will be re-elected even if an overwhelming majority
of the votes cast withhold support for them - only a single affirmative vote
would be necessary to ensure their re-election!

YOU CAN MAKE YOUR VOICE HEARD BY NOT RETURNING THE WHITE PROXY CARD SENT TO YOU
BY KERR-MCGEE AND BY SIGNING, DATING AND RETURNING THE GOLD PROXY CARD IN THE
ENCLOSED POSTAGE-PREPAID ENVELOPE, WHICH WILL REVOKE ALL PRIOR PROXIES.

             WHY WON'T KERR-MCGEE ALLOW YOU TO CHOOSE FOR YOURSELF?

         In this era of sweeping corporate governance reforms and enhanced
efforts by the Securities and Exchange Commission to foster corporate democracy,
Kerr-McGee seems to be going in the opposite direction. In addition to a poison
pill, blank-check preferred stock and various other devices that could have an
anti-takeover effect (including the proposed increase in the number of
authorized shares of Common Stock described in Kerr-McGee's Proxy Statement),
Kerr-McGee has adopted numerous provisions that have the effect of preventing or
severely limiting the ability of Stockholders to act in a manner that may
challenge existing directors and management. Below is a list of only some of
these provisions:

     o   Stockholders do not have the right to call special meetings. Special
         meetings of the Stockholders may be called only by the Chief Executive
         Officer of Kerr-McGee or by the Secretary at the direction of the Board
         of Directors.

     o   Stockholders do not have the right to act by written consent. Any
         action required or permitted to be taken by the Stockholders must be
         effected at a duly called annual or special meeting of Stockholders.

     o   Stockholders may not nominate persons for election to the Board of
         Directors of Kerr-McGee or propose other business to be conducted at
         stockholder meetings unless they comply with advance notice procedures
         requiring the delivery of information to Kerr-McGee not less than 70
         days nor more than 90 days prior to the first anniversary of the
         preceding year's annual meeting.



                                       4


     o   Kerr-McGee's Board of Directors is staggered - i.e., the Board of
         Directors is divided into three classes, with each class being elected
         for a term of three years. The effect of this classification of
         directors is that Stockholders are only able to elect approximately
         one-third of the Board of Directors each year.

     o   Any vacancies in the Board of Directors, as well as newly created
         directorships resulting from any increase in the authorized number of
         directors, may be filled only by a majority of the remaining directors
         then in office.

     o   Directors may be removed from the Board only for cause, and then only
         by a supermajority Stockholder vote.

     o   Kerr-McGee's certificate of incorporation provides that no director
         shall be liable to Kerr-McGee -- or to the Stockholders -- for monetary
         damages for breach of fiduciary duty as a director.

Ask yourself - are these provisions in place for YOUR benefit? Or are these
provisions in place to help ensure that Kerr-McGee's directors remain
unchallenged, regardless of how poorly they perform? It seems to us rather
backwards that the owners of Kerr-McGee - the Stockholders - should be hampered
in their efforts to effect change by the Board of Directors -- the very people
the Stockholders have appointed to safeguard their interests! Kerr-McGee's
directors and executive officers have only a tiny stake in Kerr-McGee - 1.3%,
according to Kerr-McGee's Proxy Statement. Should this small group be permitted
to prevent the holders of over 98% of Kerr-McGee's stock from having the freedom
to choose their own fiduciaries? We think not. The absurdity of this situation
may be illustrated by the following analogy. Imagine that the owners of a store
have hired a security guard to protect their business - should that security
guard be allowed to prevent the owners from entering their own store to make
changes? Should that security guard further be allowed to prevent his employers
from finding a new security guard in the event that he does not perform his
duties to the satisfaction of the owners? We think not.

THE NOMINEES ARE COMMITTED TO ACTING IN THE BEST INTEREST OF ALL THE
STOCKHOLDERS. WE BELIEVE THAT YOUR VOICE IN THE FUTURE OF KERR-MCGEE CAN BEST BE
EXPRESSED THROUGH THE ELECTION OF CARL C. ICAHN AND BARRY S. ROSENSTEIN.
ACCORDINGLY, WE URGE YOU TO SIGN AND RETURN YOUR GOLD PROXY CARD TODAY.

IF YOU HAVE ALREADY SUBMITTED A KERR-MCGEE PROXY, YOU MAY REVOKE YOUR PROXY BY
DELIVERING A LATER-DATED GOLD PROXY CARD IN THE ENCLOSED POSTAGE-PREPAID
ENVELOPE. WE WILL CONTINUE TO URGE KERR-MCGEE TO PERMIT US TO VOTE ALL PROXIES
AS INSTRUCTED, INCLUDING FOR THE NOMINEES.

YOU MAY ALSO REVOKE ANY PROXY YOU HAVE ALREADY GRANTED BY ATTENDING THE ANNUAL
MEETING AND VOTING IN PERSON.

IF YOUR SHARES ARE HELD IN THE NAME OF A BROKERAGE FIRM, BANK, BANK NOMINEE OR
OTHER INSTITUTION ON THE RECORD DATE, ONLY IT CAN VOTE SUCH SHARES AND ONLY UPON
RECEIPT OF YOUR SPECIFIC INSTRUCTIONS.


                                       5



ACCORDINGLY, PLEASE CONTACT THE PERSON RESPONSIBLE FOR YOUR ACCOUNT AND INSTRUCT
THAT PERSON TO EXECUTE ON YOUR BEHALF THE GOLD PROXY CARD AS SOON AS POSSIBLE.

         Mr. Icahn, Mr. Rosenstein and each of the other Participants have no
interest in Kerr-McGee other than as Stockholders.

IMPORTANT

         The election of the Nominees requires the affirmative vote of a

herein shall be deemed to be an admission by any of (i) the Icahn Parties that
they are the beneficial owners of shares beneficially owned by the JANA Parties
or (ii) the JANA Parties that they are the beneficial owners of shares
beneficially owned by any of the Icahn Parties.

BACKGROUND

         On or about January 20, 2005, Barry S. Rosenstein and August H. Roth
spoke with Robert Wohleber (the CFO of Kerr-McGee), Rick Buterbaugh (the head of
investor relations of Kerr-McGee) and David Hager (the head of exploration of
Kerr-McGee) and discussed their respective views regarding the sale of
Kerr-McGee's chemicals business and regarding Kerr-McGee generally.

         On February 10, 2005, representatives of the Icahn Parties and the JANA
Parties had a meeting in which they discussed Kerr-McGee. The parties also
discussed the possibility of JANA Master selling to the Icahn Parties an option
to purchase shares of Common Stock.

         On February 14, 2005, the Icahn Parties acquired, for $1,500,000, an
option (the "JANA Option") to purchase, in the aggregate, 250,000 shares of
Common Stock of Kerr-McGee from JANA Master. Pursuant to the exercise of the
JANA Option on March 1, 2005, Icahn Partners purchased 96,000 shares of Common
Stock, Icahn Master purchased 104,000 shares of Common Stock and High River
purchased 50,000 shares of Common Stock. The JANA Option had an exercise price
of $60.00 per share and an expiration date of August 14, 2005.

         On or about February 23, 2005 and on or about March 3, 2005, Carl C.
Icahn and Mr. Rosenstein spoke with Luke Corbett (the CEO of Kerr-McGee), and
suggested various actions to be taken by Kerr-McGee that they believed would
enhance stockholder value.

         On March 2, 2005, the Icahn Parties delivered a letter to Kerr-McGee,
notifying Kerr-McGee that the Icahn Parties intend to appear at the Annual
Meeting, in person or by proxy, to


                                       11



nominate and seek to elect Carl C. Icahn and Barry S. Rosenstein as members of
the board of directors of Kerr-McGee.

         On March 3, 2005, Carl C. Icahn and Barry S. Rosenstein sent a letter
to Kerr-McGee, proposing that Kerr-McGee (i) sell its chemical business, (ii)
enter into a volumetric production payment ("VPP") transaction to sell future
production of a portion of its reserves and (iii) utilize the proceeds to buy
back shares of its stock at a price of $90 per share. Under the terms of a VPP
transaction, an energy producer arranges to receive an up-front payment of cash
from a counterparty in exchange for a fixed-term commitment to deliver oil and
gas in the future from one or more producing oil or gas wells. The producer
typically retains control of the properties and rights to future development
drilling, as well as production above the VPP volumes. A VPP transaction allows
the producer to monetize a portion of its reserves while providing a predictable
supply of oil or gas to the counterparty. Messrs. Icahn and Rosenstein believe
that their proposal could create value for Stockholders because it would permit
Kerr-McGee to take advantage of the spread between the valuation that the stock
market currently places on Kerr-McGee on a per barrel of oil equivalent of
proved reserves basis and the higher value at which oil and gas futures are
trading in the commodity markets.

         On March 10, 2005, Carl C. Icahn and Barry S. Rosenstein sent a letter
to Kerr-McGee, responding to Kerr-McGee's March 8, 2005 announcement regarding
the proposed sale of its chemicals business and share repurchase program.
Messrs. Icahn and Rosenstein wrote that they were encouraged that Kerr-McGee had
agreed with their position with respect to the sale of its chemicals business,
but also expressed dissatisfaction that the board did not address the arbitrage
opportunity outlined in their March 3rd letter. Messrs. Icahn and Rosenstein
reiterated their belief that if Kerr-McGee were to consummate the VPP
transaction described in the March 3rd letter, it would unlock significant
shareholder value. Further, in response to Kerr-McGee's characterization of
their proposal as an attempt to earn "quick cash," Messrs. Icahn and Rosenstein
stated that, given current market conditions, if Kerr-McGee were to consummate
the VPP transaction they proposed and commence a tender offer to repurchase its
shares at $90 per share, they would commit not to sell their shares in such an
offer.

         On March 10, 2005, Kerr-McGee filed a lawsuit in federal court in
Oklahoma against the Icahn Parties, the JANA Parties and certain of their
respective affiliates. The amended complaint in this action, which was filed by
Kerr-McGee on March 14, 2005, claims: (i) that the Icahn Parties and the JANA
Parties have violated their disclosure obligations under Section 13(d) of the
Exchange Act, including by filing misleading Schedules 13D which falsely
disclaim that they are acting with each other as a group, and mischaracterize
their purpose in acquiring shares; (ii) that the March 2, 2005 letter in which
the Icahn Parties notified Kerr-McGee of their intention to seek to elect Carl
C. Icahn and Barry S. Rosenstein to the board of directors fails to comply with
Kerr-McGee's bylaws; and (iii) that the Icahn Parties and the JANA Parties have
violated Section 14(a) of the Exchange Act and Rule 14a-9 thereunder by filing
false and misleading proxy solicitation materials. The lawsuit requests that the
court enter a judgment: (i) declaring the March 2, 2005 letter from the Icahn
Parties invalid; (ii) ordering the Icahn Parties and the JANA Parties to file
accurate disclosures in accordance with the requirements of Sections 13(d) and
14(a) of the Exchange Act and the regulations promulgated thereunder; (iii)
enjoining the Icahn Parties and the JANA Parties from voting any shares acquired
prior to the filing of true and accurate Schedules 13D; (iv) ordering the Icahn
Parties and the JANA Parties to return any proxies received prior to the filing
of true and accurate disclosures under Section 14(a) of the Exchange Act and the
regulations promulgated thereunder; (v) enjoining the Icahn Parties and


                                       12


the JANA Parties from undertaking any action -- including (without limitation)
soliciting proxies, exercising stockholder voting rights, or purchasing
additional shares of Kerr-McGee --designed to change or affect control of
Kerr-McGee until 30 days following the filing of such true and accurate
disclosures pursuant to Sections 13(d) and 14(a) of the Exchange Act; and (vi)
granting such other and further relief as the court may deem just and proper.

         On March 17, 2005, Messrs. Corbett, Wohleber, Buterbaugh and Hager
visited with Mr. Icahn, Vincent J. Intrieri and Keith A. Meister and discussed
their respective views regarding the sale of Kerr-McGee's chemicals business,
the VPP transaction and the stock repurchase that had been proposed by Messrs.
Icahn and Rosenstein.

         On March 17, 2005, the Icahn Parties sent a letter to Kerr-McGee
demanding, pursuant to Delaware law, the right as stockholders to inspect
certain documents and records of Kerr-McGee (including stockholder list
materials).

         On March 18, 2005, Messrs. Corbett, Wohleber, Buterbaugh and Hager
visited with Messrs. Rosenstein and Roth and discussed their respective views
regarding the sale of Kerr-McGee's chemicals business, the VPP transaction and
the stock repurchase that had been proposed by Messrs. Icahn and Rosenstein.

         On April 4, 2005, Carl C. Icahn and Barry S. Rosenstein sent a letter
to the Board of Directors of Kerr-McGee urging them to allow the Stockholders
the opportunity to choose their own directors instead of running a single ballot
election.

         On April 4, 2005, the Icahn Parties filed an answer to Kerr-McGee's
lawsuit, denying all material allegations and requesting a judgment dismissing
Kerr-McGee's amended complaint in its entirety, together with attorney's fees,
costs and disbursements incurred in defending the action, and such further
relief as the Court may deem just and proper.

         Appendix I attached hereto sets forth, as to each of the Participants,
all transactions in securities of Kerr-McGee effected during the past two years.
Appendix II attached hereto sets forth information with respect to all options
to purchase shares of Common Stock owned beneficially by the JANA Parties.

         Except as set forth herein or in any of the Appendices attached hereto,
neither of the Nominees nor or any of the other Participants: (i) owns any
securities of Kerr-McGee of record but not beneficially; (ii) owns beneficially
any securities of Kerr-McGee or any parent or subsidiary of Kerr-McGee; (iii)
has any agreement or understanding with any person with respect to any future
employment by Kerr-McGee or its affiliates; (iv) has any agreement or
understanding with any person with respect to any future transactions to which
Kerr-McGee or any of its affiliates will or may be a party; (v) has engaged in
or had a direct or indirect interest in any transaction, or series of similar
transactions, since the beginning of Kerr-McGee's last fiscal year, or any
currently proposed transaction, or series of similar transactions, to which
Kerr-McGee or any of its subsidiaries was or is to be a party, in which the
amount involved exceeds $60,000; (vi) borrowed any funds for the purpose of
acquiring or holding any securities of Kerr-McGee; or (vii) is presently, or has
been within the past year, a party to any contract, arrangement or understanding

Other Proposals

         The Participants and their affiliates know of no other business to be
presented at the 2005 Annual Meeting. If any other matters should properly come
before the Annual Meeting and the shares represented by GOLD proxy cards are
present at the Annual Meeting, it is intended that the persons named on the
enclosed GOLD proxy card will vote that proxy on such other matters in
accordance with their judgment (provided, however, that the persons named on the
enclosed GOLD proxy card will be permitted to use such discretionary authority
only for matters which the Participants do not know, a reasonable time before
the solicitation, are to be presented at the Annual Meeting).

VOTING PROCEDURES

         According to Kerr-McGee's Proxy Statement, the voting procedures are as
set forth below.

         A majority of the shares of the Common Stock of Kerr-McGee, present in
person or represented by proxy, shall constitute a quorum for purposes of the
Annual Meeting. Abstentions and broker non-votes are considered to be shares
present for the purpose of determining whether a quorum exists. A broker
non-vote occurs when a nominee holding shares for a beneficial owner does not
vote on a particular proposal because the nominee does not have discretionary
voting power with respect to that item and has not received voting instructions
from the beneficial owner.

         Directors shall be elected by a plurality of the votes present in
person or represented by proxy at the Annual Meeting and entitled to vote on the
election of directors. Abstentions and broker non-votes are not counted as votes
present for the purpose of electing directors. The proposal to amend the Amended
and Restated Certificate of Incorporation of Kerr-


                                       15


McGee requires the affirmative vote of a majority of the outstanding shares of
Common Stock. Abstentions and broker non-votes will have the effect of votes
against the proposal to amend the Amended and Restated Certificate of
Incorporation of Kerr-McGee. In all matters other than the election of directors
and the amendment of the Amended and Restated Certificate of Incorporation of
Kerr-McGee, the affirmative vote of a majority of shares present in person or
represented by proxy at the Annual Meeting and entitled to vote on the subject
matter shall be the act of the Stockholders. With respect to such matters,
broker non-votes are not considered to be shares present in person or
represented by proxy, but abstentions are considered to be shares present in
person or represented by proxy, and, therefore, abstentions will have the effect
of votes against the proposal.

         The New York Stock Exchange has determined that the appointment of
independent auditors is a "routine" item. Therefore, a broker or nominee may
vote shares held by it with respect to that item if no instructions have been
received for it at least 15 days before the Annual Meeting.

         You are urged to complete the enclosed GOLD proxy and return it in the
enclosed self-addressed, prepaid envelope. All valid proxies received prior to
the Annual Meeting will be voted. If you specify a choice with respect to any
item by marking the appropriate box on the proxy, the shares will be voted in
accordance with that specification. In the event that Kerr-McGee succeeds in
obtaining a court order declaring the nominations of Carl C. Icahn and Barry S.
Rosenstein invalid, your shares may not be voted for the election of directors
at the Annual Meeting.

IF NO SPECIFICATION IS MADE, THE PERSONS NAMED ON THE ENCLOSED GOLD PROXY CARD
WILL VOTE YOUR SHARES FOR CARL C. ICAHN AND BARRY S. ROSENSTEIN WITH RESPECT TO
PROPOSAL 1, AND WILL ABSTAIN FROM VOTING WITH RESPECT TO THE REMAINING
PROPOSALS.


PROXY PROCEDURES

IN ORDER TO SUPPORT THE NOMINEES, PLEASE MARK, SIGN, DATE AND RETURN THE
ENCLOSED GOLD PROXY CARD IN THE ENCLOSED POSTAGE-PREPAID ENVELOPE. IN THE EVENT
THAT THE NOMINATIONS OF CARL C. ICAHN AND BARRY S. ROSENSTEIN ARE PERMITTED, WE
WILL VOTE ALL GOLD PROXIES AS INSTRUCTED (OR IF NO INSTRUCTION IS GIVEN, FOR THE
ELECTION OF THE NOMINEES AND ABSTAINING ON ALL OTHER MATTERS). IF KERR-MCGEE
SUCCEEDS IN OBTAINING A COURT ORDER DECLARING THE NOMINATIONS OF CARL C. ICAHN
AND BARRY S. ROSENSTEIN INVALID, YOUR SHARES MAY NOT BE VOTED IN THE ELECTION OF
DIRECTORS AT THE MEETING.


Revocation of Proxies

         Any Stockholder who has mailed a white proxy card to Kerr-McGee may
revoke it before it is voted by mailing a duly executed GOLD proxy card to the
Participants bearing a date LATER than the white proxy card delivered to
Kerr-McGee. Proxies may also be revoked at


                                       16


any time prior to voting by: (i) delivering to the corporate secretary of
Kerr-McGee, a written notice, bearing a date later than the date of the proxy,
stating that the proxy is revoked; (ii) delivering a duly executed proxy bearing
a later date than the proxy delivered previously; or (iii) attending the Annual
Meeting and voting in person.

         Only holders of record as of the close of business on the Record Date
will be entitled to vote. If you were a Stockholder of record on the Record
Date, you will retain your voting rights at the Annual Meeting even if you sell
such shares after the Record Date. Accordingly, it is important that you vote
the shares held by you on the Record Date, or grant a proxy to vote such shares
on the GOLD proxy card, even if you sell such shares after the Record Date.

IF YOUR SHARES ARE HELD IN THE NAME OF A BROKERAGE FIRM, BANK, BANK NOMINEE OR
OTHER INSTITUTION ON THE RECORD DATE, ONLY IT CAN VOTE SUCH SHARES AND ONLY UPON
RECEIPT OF YOUR SPECIFIC INSTRUCTIONS. ACCORDINGLY, PLEASE CONTACT THE PERSON
RESPONSIBLE FOR YOUR ACCOUNT AND INSTRUCT THAT PERSON TO EXECUTE ON YOUR BEHALF
THE GOLD PROXY CARD AS SOON AS POSSIBLE.


COST AND METHOD OF SOLICITATION

         Solicitation of proxies shall be made by Messrs. Icahn, Meister,
Intrieri, Rosenstein and Roth.

         The Icahn Parties and the JANA Parties have retained D.F. King & Co.,
Inc. ("King") to conduct the solicitation, for which King is to receive a fee of
approximately $200,000, plus a fee per call and reimbursement for its reasonable
out-of-pocket expenses. The Icahn Parties and the JANA Parties have agreed to
indemnify King against certain liabilities and expenses, including certain
liabilities under the federal securities laws. Insofar as indemnification for
liabilities arising under the federal securities laws may be permitted to King
pursuant to the foregoing provisions, we have been informed that in the opinion
of the Securities and Exchange Commission, such indemnification is against
public policy and is therefore unenforceable. Proxies may be solicited by mail,
courier services, Internet, advertising, telephone or telecopier or in person.
It is anticipated that King will employ approximately 100 persons to solicit
proxies from Stockholders for the Annual Meeting. The total expenditures in
furtherance of, or in connection with, the solicitation of proxies is
approximately $500,000 to date, and is estimated to be approximately $1,000,000
in total.

         The Icahn Parties and the JANA Parties agreed on March 24, 2005 to each
pay half of all costs related to the solicitation of proxies (including
expenditures for public relations and financial advisers, proxy solicitors,
advertising, printing, transportation and related expenses), except that the
Icahn Parties and the JANA Parties will each bear their own legal expenses. The
Icahn Parties and the JANA Parties intend to seek reimbursement for the costs
and expenses associated with the proxy solicitation in the event that the
Nominees are elected to the Board of Directors of Kerr-McGee, but do not intend
to submit the issue of reimbursement to a vote of security holders.
