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 plurality of the votes cast, assuming a quorum is present or otherwise represented at the Annual Meeting. As a result, your vote is extremely important in deciding the future of Kerr-McGee. We urge you to mark, sign, date and return the enclosed GOLD proxy card today. Only holders of record of Kerr-McGee's voting securities as of the close of business on March 11, 2005 (the "Record Date") are entitled to notice of, and to attend and to vote at, the Annual Meeting and any adjournments or postponements thereof. According to the proxy statement of Kerr-McGee filed with the Securities and Exchange Commission ("Kerr-McGee's Proxy Statement"), as of the Record Date, there were outstanding 163,442,818 shares of common stock, par value $1.00 per share (the "Common Stock"). Stockholders of record at the close of business on the Record Date will be entitled to one vote at the Annual Meeting for each share of Common Stock of Kerr-McGee held on the Record Date. As of the Record Date, the Participants and their affiliates beneficially owned an aggregate of 9,907,100 shares of Common Stock, representing approximately 6.1% of the outstanding shares of Common Stock.1 The Participants and their affiliates intend to vote such shares FOR the election of the Nominees.

In January 2003, Mr. Icahn became Chairman of the Board and a director of XO Communications, Inc., a telecommunications company. BARRY S. ROSENSTEIN, age 46, is the founder and Managing Partner of JANA, a position he has held since 2001. Mr. Rosenstein also founded, and from 1993 to 2001 served as Managing Partner of, Sagaponack Partners L.P., a private equity fund. He received his M.B.A. from the University of Pennsylvania's Wharton School of Business in 1984. In 1981, Mr. Rosenstein graduated Phi Beta Kappa from Lehigh University. Mr. Rosenstein is also a C.P.A. Mr. Rosenstein serves on the board of directors of Cobra Electronics and Marisa Christina, Inc. 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 with any person with respect to securities of Kerr-McGee. 13 OTHER MATTERS TO BE CONSIDERED AT THE ANNUAL MEETING According to Kerr-McGee's Proxy Statement, Kerr-McGee is soliciting proxies with respect to four proposals other than the election of directors. Please refer to Kerr-McGee's Proxy Statement for a detailed discussion of these proposals, including various arguments in favor of and against such proposals. These proposals are discussed briefly below. THE PARTICIPANTS MAKE NO RECOMMENDATION AS TO THESE PROPOSALS AND INTEND TO ABSTAIN FROM VOTING THEREON. IF YOU HAVE SIGNED THE GOLD PROXY CARD AND NO MARKING IS MADE, YOU WILL BE TREATED AS HAVING GIVEN A DIRECTION TO ABSTAIN FROM VOTING ALL THE SHARES REPRESENTED BY THE GOLD PROXY CARD WITH RESPECT TO THESE PROPOSALS AND THE PERSONS NAMED IN THE GOLD PROXY CARD WILL ACT ACCORDINGLY. Item 2 -- Ratification of Appointment of Independent Auditors At the Annual Meeting, the Stockholders will be asked to ratify the appointment of Ernst & Young LLP as Kerr-McGee's independent auditors for 2005. Kerr-McGee's board of directors unanimously recommended a vote for this proposal. The Participants make no recommendation as to this proposal. Voting on Item 2 The accompanying GOLD proxy card will be voted in accordance with your instruction on such card. You may vote for or vote against, or abstain from voting on, Item 2 described above by marking the proper box on the GOLD proxy card. Item 3 - Approval of the 2005 Long Term Incentive Plan At the Annual Meeting, the Stockholders will be asked to approve Kerr-McGee's 2005 Long Term Incentive Plan to replace the 2002 Long Term Incentive Plan. Kerr-McGee's board of directors unanimously recommended a vote for this proposal. The Participants make no recommendation as to this proposal. Voting on Item 3 The accompanying GOLD proxy card will be voted in accordance with your instruction on such card. You may vote for or vote against, or abstain from voting on, Item 3 described above by marking the proper box on the GOLD proxy card. Item 4 - Approval to Amend the Amended and Restated Certificate of Incorporation to Increase the Authorized Number of Shares of Common Stock from 300,000,000 to 500,000,000 At the Annual Meeting, the Stockholders will be asked to approve an amendment to Kerr-McGee's Amended and Restated Certificate of Incorporation to increase the authorized number of shares of Common Stock from 300,000,000 to 500,000,000. Kerr-McGee's board of directors unanimously recommended a vote for this proposal. The Participants make no recommendation as to this proposal. 14 Voting on Item 4 The accompanying GOLD proxy card will be voted in accordance with your instruction on such card. You may vote for or vote against, or abstain from voting on, Item 4 described above by marking the proper box on the GOLD proxy card. Item 5 - Stockholder Proposal Requesting Establishment of an Office of the Board of Directors At the Annual Meeting, the Stockholders will be presented with a stockholder proposal requesting establishment of an Office of the Board of Directors. Kerr-McGee's board of directors unanimously recommended a vote against this proposal. The Participants make no recommendation as to this proposal. Voting on Item 5 The accompanying GOLD proxy card will be voted in accordance with your instruction on such card. You may vote for or vote against, or abstain from voting on, Item 5 described above by marking the proper box on the GOLD proxy card. 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. 17 ADDITIONAL INFORMATION Certain information regarding the securities of Kerr-McGee held by Kerr-McGee's Directors, nominees, management and 5% Stockholders is contained in Kerr-McGee's Proxy Statement. Information concerning the date by which proposals of security holders intended to be presented at the next annual meeting of Stockholders of Kerr-McGee must be received by Kerr-McGee for inclusion in Kerr-McGee's Proxy Statement and form of proxy for that meeting is also contained in Kerr-McGee's Proxy Statement. Although the Participants do not have any knowledge that would indicate that any such information is untrue, the Participants do not take any responsibility for the accuracy or completeness of the information contained in Kerr-McGee's public filings, or any failure by Kerr-McGee to disclose events that may affect the significance or accuracy of any such information.
