The Board of Directors urges you not to mail, sign or vote any proxy cards sent to you by the Icahn Group even as a vote of protest because a submission of a Icahn Group proxy card will revoke your previously voted proxy card in support of the Board of Directors' nominees.

Proxy Statement for the
2005 Annual Meeting of Stockholders
on May 10, 2005, at 9:00 a.m.

The accompanying proxy is solicited on behalf of the Board of Directors (the "Board") of Kerr-McGee Corporation (the "Company"). This Proxy Statement and the accompanying form of proxy are first being mailed to Stockholders on or about , 2005.

AGENDA FOR ANNUAL MEETING

Four items of business are scheduled for the 2005 Annual Meeting, as follows:

1.: Election of two Directors;
2.: Ratification of the appointment of Ernst & Young LLP as the Company's independent auditors;
3.: Approval of the 2005 Long Term Incentive Plan; and
4.: Stockholder proposal requesting establishment of an Office of the Board of Directors.

All of these items are discussed below.

The Board unanimously recommends a vote "FOR" each of Items 1, 2 and 3 and a vote "AGAINST" Item 4.

INFORMATION CONCERNING POSSIBLE COMPETING NOMINATIONS

The Company received notice from Carl C. Icahn and the Icahn Partners Master Fund LP that each made a filing under the Hart-Scott-Rodino Antitrust Improvements Act ("HSR Act") for clearance for each to acquire more than $100 million but less than $500 million of the Company's common stock.

On March, 2 2005, the Icahn Group, consisting of Icahn Partners LP, Icahn Partners Master Fund LP and High River Limited Partnership, sent a notice to the Company indicating that they intend to nominate their own slate of two nominees to the Company's Board of Directors at the Annual Meeting. The Company does not know if the Icahn Group will pursue such nominations. If you receive proxy materials from the Icahn Group, the Company urges you not to sign or return the Icahn Group's proxy card. The Company is currently reviewing the notice received from the Icahn Group to determine whether it complies with all applicable requirements.

VOTING SECURITIES

The Company's only class of voting securities is its common stock, having a par value of $1.00 per share ("Common Stock"), of which there were shares outstanding as of the close of business on March 11, 2005, the record date for Stockholders entitled to receive notice of and to vote at the Annual Meeting. Each share is entitled to one vote. The number of shares outstanding does not include treasury stock, which will not be voted.

Under Section 216 of the Delaware General Corporation Law and the Kerr-McGee Corporation ByLaws (the "ByLaws"), a majority of the shares of the common stock of the Company, 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. In all matters other than the election of Directors, 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 2005 Annual Meeting.

Stockholders of record may appoint proxies to vote their shares in one of three ways, depending on where they are located:

1.: Via Internet pursuant to the instructions on the enclosed proxy card;
2.: Calling the toll-free number on the proxy card; or
3.: Signing, dating and mailing the white proxy card in the envelope provided.

Proxies will be voted as directed, unless revoked at or before the Annual Meeting on May 10, 2005. Any Stockholder who attends the Annual Meeting and elects to vote in person may at the meeting revoke a previously designated proxy. Otherwise, revocation of a proxy will be effective only if a Stockholder advises the Corporate Secretary of the revocation in a writing, including a later-dated proxy, that is received by the Corporate Secretary on or before May 9, 2005.

Item No. 1
ELECTION OF TWO DIRECTORS

On the recommendation of the Corporate Governance and Nominating Committee, the Board has nominated William F. Wallace and Ian L. White-Thomson for election as Directors for a term expiring at the 2008 Annual Meeting, and in each case until their respective successors are elected and qualified. Mr. Wallace and Mr. White-Thomson are currently Directors of the Company whose terms expire at the 2005 Annual Meeting.

All of the Board's nominees have consented to serve, and the Company has no reason to believe any nominee will be unavailable. Should any of the Board's nominees become unavailable for any reason, the proxies will be voted for a substitute nominee to be named by the Board, unless the Board reduces the number of Directors constituting the full Board.

Biographical and other information about each of the nominees is set forth in this Proxy Statement beginning on Page [ ] under "Director Information."

At the Annual Meeting, the Stockholders will vote on the election of each of the nominees to the Board.The Board unanimously recommends a vote "FOR" the election to the Board of each of the nominees.

INFORMATION ABOUT THE BOARD

Operations and Meetings

Directors are expected to attend substantially all annual stockholder meetings, Board meetings and meetings of the committees of the Board on which they serve. During 2004, the Board held seven meetings, with each Director attending 75% or more of the aggregate number of meetings of the Board and of the committees of the Board on which each such Director served, and all Directors attending the 2004 Annual Meeting of Stockholders.

The Board's operation and responsibilities are governed by the Company's Certificate of Incorporation, ByLaws, Corporate Governance Guidelines, charters for the Board's standing committees and the laws of the State of Delaware. The Certificate of Incorporation, ByLaws, Corporate Governance Guidelines, and committee charters are available on the Company's website (www.kerr-mcgee.com). Directors discharge their responsibilities not only by attending Board and committee meetings but also through communication with the Chairman and Chief Executive Officer and other members of management about matters of interest and concern to the Company.

Lead Director

The Board has designated Mr. Bradford as its lead non-management Director ("Lead Director"). As Lead Director, Mr. Bradford is responsible for leading meetings of the non-management Directors, facilitating communications between non-management Directors and the Chairman and Chief Executive Officer, providing guidance to the Chairman and Chief Executive Officer regarding the agenda for Board meetings and for such other matters as may be determined by the Board from time to time.

Committees

The Board has established and currently maintains an Audit Committee, an Executive Compensation Committee, and a Corporate Governance and Nominating Committee as standing committees.

Audit Committee

The Audit Committee acts on behalf of the Board with respect to the engagement of the Company's independent auditors and with respect to the authorization of all audit and other services provided to the Company by its internal and independent auditors. In addition, the committee assists the Board with the oversight of the Company's financial statements, financial reporting process, systems of internal accounting and financial controls, disclosure controls and procedures, and compliance with legal and regulatory requirements. The committee also evaluates enterprise risk issues and the performance of internal and independent auditors, among other things.

The Audit Committee is currently comprised of the following Directors: Mr. Richie (Chair), Mr. Bradford, Mr. Genever-Watling, Mr. Wallace, Ms. Walters and Mr. White-Thomson. The Board has determined that Mr. Genever-Watling and Ms. Walters are "audit committee financial experts," as that term is defined by the Securities and Exchange Commission. The Audit Committee met seven times in 2004. In addition, the Chair of the Audit Committee held conference calls each quarter with the Company's independent auditors and with the Company's Chief Accounting Officer in conjunction with the release of quarterly earnings. The Report of the Audit Committee begins on Page . The charter of the Audit Committee, which has been approved by the Board, is included in this Proxy Statement as Exhibit A.

Executive Compensation Committee

The Executive Compensation Committee evaluates and determines the salary and benefits of the Chief Executive Officer and reviews the salaries and benefits determined by the Chief Executive Officer for all other officers of the Company, recommending to the full Board such changes as it may deem appropriate. In addition, the Executive Compensation Committee determines the incentive compensation awards for all officers and administers the Annual Incentive Compensation Plan, the Long Term Incentive

Plan, the Executive Deferred Compensation Plan, the Deferred Compensation Plan for Non-Employee Directors and the Supplemental Executive Retirement Plan. A subcommittee of the Executive Compensation Committee makes determinations regarding cash bonuses for the Company's officers after an initial review by the full committee.

The Executive Compensation Committee is currently comprised of the following Directors: Mr. Bradford, Dr. Earle, Mr. Genever-Watling, Dr. Jischke, Mr. Richie, Mr. Wallace, Ms. Walters and Mr. White-Thomson. All members of the Executive Compensation Committee meet the definitions of (i) a "non-employee director" within the meaning of Rule 16b-3 promulgated under the Securities Exchange Act of 1934, as amended, and (ii) an "outside director" within the meaning of Section 162(m) of the Internal Revenue Code of 1986, as amended. The committee and its subcommittee met a total of three times in 2004. The report of the Executive Compensation Committee begins on Page .

Corporate Governance and Nominating Committee

The Corporate Governance and Nominating Committee recommends to the Board nominees for election to the Board based on criteria for nomination as a Director that have been approved by the Board, which can be found on the Company's website. In making its recommendations to the Board, the committee will consider and review the background and qualifications of candidates recommended to it by current Board members as well as candidates recommended by Stockholders. Recommendations should be made in writing and be addressed to the Chair of the Corporate Governance and Nominating Committee and sent c/o the Corporate Secretary, Kerr-McGee Corporation, P.O. Box 25861, MT-29, Oklahoma City, Oklahoma 73125.

A Stockholder recommendation should set forth (i) the name and address of and number of shares of Company stock owned by each of the recommending Stockholder and the recommended candidate, (ii) information relating to the recommended candidate that would be required to be disclosed in solicitation of proxies for the election of the candidate pursuant to Regulation 14A under the Securities Exchange Act of 1934, (iii) a description of all agreements related to the nomination among the recommending Stockholder, the recommended candidate and/or other persons, (iv) the notarized written consent of the recommended candidate to be named in the proxy statement as a nominee and to serve as a Director if elected and (v) any other information the recommending Stockholder believes would be useful in informing the committee's decision making.

The committee begins considering candidates in the fall of the year before the annual meeting at which Directors are to be elected. Accordingly, any stockholder recommendation should be submitted in sufficient time to enable the committee to evaluate the recommendation on its regular fall timetable. When a qualified incumbent Director is willing to stand for reelection, the committee may, in its discretion, give precedence to the Director when recommending nominees to the Board.

The committee also makes recommendations to the Board regarding corporate governance and oversees the evaluation of the Board and management. The Corporate Governance and Nominating Committee currently consists of the following Directors: Dr. Earle (Chair), Mr. Bradford, Mr. Genever-Watling, Dr. Jischke, Mr. Richie, Ms. Walters and Mr. White-Thomson. The Corporate Governance and Nominating Committee met four times in 2004.

Independence

The Board has adopted categorical standards to assist it in making determinations regarding the independence of Directors, including whether a Director has a material relationship with the Company. The standards can be found on the Company's website under the Investor Relations and Corporate Governance links. The Board of Directors has determined that each of the Directors, other than Mr. Corbett, is independent under both the New York Stock Exchange listing standards and the standards adopted by the Board. In addition, the Audit, Executive Compensation, and Corporate Governance and Nominating Committees are comprised entirely of independent directors, and the Audit Committee members meet Securities and Exchange

Commission eligibility standards applicable to Audit Committee members.

Compensation

Directors who are not employees of the Company are paid an annual retainer fee of $50,000 and a fee of $2,000 for each meeting attended, including meetings of the Board and Board committees and subcommittees, certain meetings held by committee chairs or the Lead Director, and meetings held by other Board members at the request of or on behalf of the Board or a committee. In addition, the Lead Director is paid an annual fee of $30,000; the Audit Committee Chair is paid an annual fee of $12,000; and other committee chairs are paid an annual fee of $6,000. Under the 2002 Kerr-McGee Corporation Long Term Incentive Plan approved by the Stockholders at the 2002 Annual Meeting, non-employee Directors also are granted each year 1,500 shares of restricted Common Stock and 4,000 options to purchase shares of Common Stock at the market price prevailing on the date of the grant. Directors are reimbursed for travel expenses and lodging and other out-of-pocket expenses they incur in connection with their service on the Board. Directors periodically receive mementos in connection with meetings of the Board. Taxes payable on such items are paid by the Company and totaled less than $1,100 per person in 2004.

Pursuant to the Deferred Compensation Plan for Non-Employee Directors, any Director who is not an employee of the Company may elect to defer any cash compensation earned as a Director. Similarly, any Director who is not an employee of the Company may elect to defer gain attributable to stock options or stock appreciation rights and any portions of restricted stock awards. Deferred compensation, together with any associated gain, loss or earnings, will be paid at the Director's retirement, either in a single lump sum payment or in five, ten, or fifteen equal annual installments, or at another selected date, as determined by the Director.

Communicating with the Board of Directors

The Board of Directors has established methods for Stockholders to communicate with the Board. Stockholders wishing to communicate with one or more Directors or the Board as a whole may do so in a writing addressed to the Director(s) or the Board and sent to the Corporate Secretary, Kerr-McGee Corporation, P.O. Box 25861, MT-29, Oklahoma City, Oklahoma 73125. Stockholders also may communicate with Directors by e-mail addressed tokerr-mcgeedirectors@kmg.com.

In addition, Stockholders can communicate with Directors by calling Kerr-McGee's anonymous and confidential Hotline at 800-867-5118 in the U.S. and Canada and from other locations internationally by dialing the applicable country code and 405-270-2559 (calls from certain international locations can be made toll free by using other telephone numbers found on the Company's website). The Corporate Secretary reports to the Audit Committee any calls made to the Kerr-McGee Hotline regarding accounting, internal accounting controls or auditing matters and informs non-management Directors of reports made to the Kerr-McGee Hotline that are intended for non-management Directors. Information about the Kerr-McGee Hotline can be found on the Company's website.

At the Board's direction, the Company's Corporate Secretary receives all Stockholder communications and forwards directly to the intended recipient all Stockholder communications that are related to corporate governance, accounting, auditing, legal compliance, human rights, or social responsibility and all other communications relevant to a Director's service on the Board. At the Board's direction, the Corporate Secretary generally does not forward "spam" communications related to solicitations for products or services, items of a personal nature not relevant to Stockholders as a whole or other matters that are of a type that render them irrelevant to the functioning of the Board.

The Chair of the Corporate Governance and Nominating Committee periodically reviews all Stockholder communications, including those not automatically forwarded to the non-management Directors, and all Directors are able to review and obtain copies of all Stockholder communications. In addition, the Corporate Secretary consults with the Lead Director as appropriate with regard to Stockholder communications.

Item No. 2
RATIFICATION OF THE APPOINTMENT OF INDEPENDENT AUDITORS

The Audit Committee of the Board has appointed Ernst & Young LLP, an independent auditing firm, as the Company's independent auditors for 2005, subject to Stockholder ratification. Ernst & Young LLP served as the Company's independent auditors for the years ended December 31, 2003 and December 31, 2004.

Representatives of Ernst & Young LLP will be present at the Annual Meeting to make a statement if they desire to do so and will be available to respond to appropriate questions from Stockholders.

At the Annual Meeting, the Stockholders will vote on the ratification of the appointment of Ernst & Young LLP as independent auditors for 2005.

The Board unanimously recommends a vote "FOR" the ratification of the appointment of Ernst & Young LLP as the Company's independent auditors.

If the appointment of Ernst & Young LLP for 2005 is not ratified by the Stockholders, the Board will reconsider the matter. If Ernst & Young LLP ceases to act as the Company's independent auditors, or if the Board removes Ernst & Young LLP as the Company's independent auditors, the Audit Committee will appoint another independent public accounting firm. The engagement of independent auditors for 2006 will be subject to ratification by the Stockholders at the 2006 Annual Meeting.

REPORT OF THE AUDIT COMMITTEE

The Audit Committee oversees the Company's financial reporting process on behalf of the Board of Directors. Management has the primary responsibility for the financial statements and the reporting process, including the systems of internal control over financial reporting.

In fulfilling its oversight responsibilities, the Committee reviewed with management the audited financial statements contained in the Annual Report. The review included a discussion of the quality, not just the acceptability, of the accounting principles, the reasonableness of significant judgments, and the clarity of disclosures in the financial statements.

The Company's independent auditors are responsible for expressing an opinion on the conformity of the audited financial statements with generally accepted accounting principles. The Committee reviewed with Ernst & Young LLP, the Company's independent auditors, Ernst & Young LLP's judgment as to the quality, not just the acceptability, of the Company's accounting principles. The Committee discussed with Ernst & Young LLP the results of the annual audit and any other matters required to be communicated to the Committee by the independent auditors under generally accepted auditing standards, applicable law, or listing standards, including matters required to be discussed by Statement on Auditing Standard No. 61, as amended by Statement on Auditing Standard No. 90. The Committee also discussed with Ernst & Young LLP the independent auditors' independence from management and the Company, including the matters contained in the written disclosures required pursuant to Rule 3600T of the Public Company Accounting Oversight Board, which adopted on an interim basis Independence Standards Board Standard No. 1, which was delivered to the Committee by Ernst & Young LLP. The Committee considered whether the provision of non-audit services by the Company's independent auditors is compatible with maintaining the auditors' independence.

The Committee discussed with both the Company's internal auditors and the independent auditors the overall scope and plans for their respective audits. The Committee met with both the internal auditors and the independent auditors, with and without management present, to discuss the results of their examinations, their evaluations of the Company's internal control over financial reporting, and the overall quality of the Company's financial reporting.

Based on the reviews and discussions referred to above, the Audit Committee recommended to the Board of Directors that the audited financial statements be included in the Annual Report on Form 10-K for the year ended 2004 for filing with the Securities and Exchange Commission. The Committee also appointed Ernst & Young LLP as the Company's independent auditors for 2005, subject to Stockholder ratification.

Item No. 3
APPROVAL OF THE 2005 LONG TERM INCENTIVE PLAN

The Board of Directors has approved and recommends that the Stockholders vote for the approval of the Kerr-McGee Corporation 2005 Long Term Incentive Plan (the "2005 Plan") to replace the 2002 Long Term Incentive Plan (the "2002 Plan").

The Board's approval and recommendation of the 2005 Plan follows a review and evaluation of the Company's existing compensation plans and a comparison of those plans with the programs offered by comparable companies. While the 2005 Plan represents, in part, a continuation of the Company's stock option program, which has been in effect since 1950, it also provides flexibility in the form and payment of awards to meet changing business needs. The primary purposes of the 2005 Plan are to:

•: align the long-term financial interests of officers, employees and non-employee directors with those of Stockholders,
•: reward officers, employees and non-employee directors for increasing the Company's common stock price over time,
•: incentivize officers, employees and non-employee directors to achieve specific goals that are aligned with stockholders' interests, and
•: attract and retain officers, key employees and non-employee directors.

The 2005 Plan includes provisions which provide for the grant of (a) stock options, (b) stock appreciation rights ("SARs"), (c) restricted stock, and (d) performance awards. The 2005 Plan would permit total equity awards over the life of the 2005 Plan of up to 10,000,000 shares, subject to the following limits:

(a)	Aggregate limit on shares designated for restricted stock and performance awards to officers and employees	3,000,000
(b)	Aggregate limit on shares designated for stock options and restricted stock to non-employee directors, of which no more than 100,000 shares may be restricted stock	300,000
(c)	Aggregate limit on shares designated for incentive stock options	1,000,000

At the Annual Meeting the Stockholders will vote on the approval of the 2005 Plan. If the 2005 Plan is approved, the current 2002 Plan will be terminated, except that awards outstanding under the 2002 Plan will remain subject to the terms of the 2002 Plan. A summary of the 2005 Plan follows and is qualified by reference to the full text of the 2005 Plan, which is included in this Proxy Statement as Exhibit B.

The Board unanimously recommends a vote "FOR" the approval of the Kerr-McGee Corporation 2005 Long Term Incentive Plan.

SUMMARY OF THE 2005 LONG TERM INCENTIVE PLAN

Term

If approved by the Stockholders, the 2005 Plan will be effective as of May 10, 2005. The 2005 Plan will terminate on May 10, 2015, unless terminated earlier by the Board of Directors. Termination of the 2005 Plan will not affect grants made prior to termination, but grants may not be made after termination.

Administration

The 2005 Plan will be administered by a committee of the Board of Directors comprised solely of two or more members who qualify both as "outside directors" under Code Section 162(m), as "non-employee directors" under Rule 16b-3 under the Securities Exchange Act of 1934 and as "independent" directors under the rules of the New York Stock Exchange (the "Committee").

Subject to the terms of the 2005 Plan, the Committee shall have authority (i) to determine the officers, employees and non-employee directors who receive awards under the 2005 Plan, (ii) to determine the size, form, terms, and conditions of awards under the 2005 Plan, (iii) to adopt, amend, or rescind rules and regulations with respect to the administration of the 2005 Plan, (iv) to interpret the 2005 Plan and make such other determinations under the 2005 Plan as the Committee deems necessary or appropriate, (v) to amend the terms and conditions of any outstanding award, subject to certain limitations including a prohibition on the repricing of options without further Stockholder approval, and (vi) to take any action that the Committee deems necessary to comply with any government laws or regulatory requirements.

Eligibility

Eligibility under the 2005 Plan is limited to officers and employees of the Company and its affiliates and the Company's non-employee directors. The Committee, in its sole discretion, shall determine which officers and employees are eligible to participate in the 2005 Plan. The Company currently estimates that approximately employees and all officers and non-employee directors will participate in the 2005 Plan.

Limits on Awards to an Officer or Employee

No officer or employee shall be awarded, during the term of the 2005 Plan, restricted stock covering more than 400,000 shares of Common Stock, or stock options covering more than 1,750,000 shares of Common Stock. In addition, no officer or employee shall be granted performance awards under the 2005 Plan during a calendar year that could result in a payment of more than $5,000,000 in cash and/or shares of Common Stock, based on the fair market value of the shares as of the first day of the performance period.

Securities Subject to the 2005 Plan

The number of shares of Common Stock that may be issued under the 2005 Plan may not exceed, in the aggregate, 10,000,000. As described above, the 2005 Plan also contains limits on the number of shares that may be issued pursuant to various types of awards under the 2005 Plan. Any shares that are subject to an award that for any reason lapses, is cancelled, or is terminated without the issuance of such shares shall again be available for awards under the 2005 Plan.

In the event of a stock split, merger, reorganization, recapitalization, stock dividend or other event described under the terms of the 2005 Plan, the Committee shall make appropriate adjustments to outstanding awards, including the number of shares subject to an award and the exercise price under a stock option or SAR, and to the number and kinds of shares which may be issued under the 2005 Plan.

On , 2005, the closing price of shares of Common Stock on the NYSE was $ .

Stock Options

The 2005 Plan authorizes awards of stock options to non-employee directors and eligible officers and employees from time to time as determined by the Committee. Subject to the limits of the 2005 Plan, the Committee may grant options for such number of shares and having such terms as the Committee designates.

Under the terms of the 2005 Plan, the Committee shall specify whether or not any

option is intended to be an incentive stock option ("Incentive Stock Option") as described in Code Section 422 or a nonstatutory or nonqualified stock option ("Nonqualified Stock Option"). The aggregate value of Common Stock with respect to which Incentive Stock Options are exercisable for the first time by an individual during any calendar year under all Company plans may not exceed $100,000. Incentive Stock Options may not be exercised more than ten years from the date of grant, and Nonqualified Stock Options may not be exercised more than ten years and one day from the date of grant. The Committee may provide for an option to be exercisable in installments during the term of the option, and the Committee may also accelerate the time at which an installment portion of an outstanding option may be exercisable.

Each stock option shall have an exercise price that is not less than the fair market value of the Common Stock on the date the option is granted. Payment for shares received upon exercise of a stock option may be made by an optionee in cash, shares of Common Stock, a combination of the foregoing, through a cashless exercise with a broker, or, in the discretion of the Committee, by the Company withholding shares of Common Stock equal in value to the exercise price of the stock option.

A stock option will terminate and may no longer be exercised three months after an officer or employee ceases to be employed for any reason other than cause, total disability, death or retirement. In the event an officer or employee ceases employment for cause, unless an option agreement provides otherwise, all outstanding options at the time of such officer's or employee's termination of employment will terminate. In the event an officer or employee ceases employment due to total disability, death or retirement, all outstanding options at the time of such officer's or employee's termination of employment will vest and will be exercisable during the remaining term of the option, not to exceed four years, as set forth in the option agreement. When a non-employee director's service terminates, outstanding options will vest immediately and remain exercisable for the remaining term of the option.

Under no circumstances will any option be exercisable after it has terminated or expired.

Stock Appreciation Rights

The 2005 Plan also authorizes the Committee to award SARs either in tandem with a stock option or independent of any option. Subject to the limits of the 2005 Plan, the Committee may grant SARs for such number of shares and having such terms as the Committee designates. A SAR provides the grantee with the right to exercise all or a portion of the SAR and receive a payment in cash equal to the excess of the fair market value of the exercised shares on the date of exercise over the aggregate exercise price of such shares. SARs shall be exercisable at such times and be subject to such restrictions and conditions as the Committee shall approve.

SARs granted in tandem with the grant of an option may be exercised for all or part of the shares subject to the related option upon the surrender of the right to exercise the equivalent portion of the related option. SARs granted in tandem with the grant of an option may be exercised only with respect to the shares for which the related option is then exercisable. SARs granted independently from the grant of an option may be exercised upon the terms and conditions specified by the Committee. The Committee shall specify the extent to which a grantee shall have the right to exercise a SAR following termination of the grantee's service.

Restricted Stock

Subject to the limits of the 2005 Plan, the Committee may grant restricted stock for such number of shares and having such terms as the Committee designates.

The Committee shall determine the nature and extent of the restrictions on grants of restricted stock, the duration of such restrictions, and any circumstances under which restricted shares will be forfeited. Restricted shares will be deposited with the Company during the period of any restriction thereon and, except as otherwise provided by the Committee during any such period of restriction, recipients shall have all of the rights of a holder of Common Stock, including but not limited to voting rights and the right to receive dividends.

If a grantee terminates service by reason of total disability, death or retirement prior to the expiration of the restriction period for a grant of

restricted stock, the restriction period will lapse and the shares will be delivered to the recipient. Unless the Committee provides otherwise, a termination of service for other reasons prior to the expiration of the applicable restriction period will result in the forfeiture of the restricted stock.

Performance Awards

The 2005 Plan permits the Committee to grant performance awards to eligible officers and employees from time to time. Performance awards may include performance units valued by reference to financial measures or property other than Common Stock and performance shares valued by reference to shares of Common Stock.

Under the terms of the 2005 Plan, the Committee shall establish the time period of not less than one year over which performance will be measured (the "Performance Period") and the performance goals used by the Committee to evaluate performance during a Performance Period. Payment of earned performance awards may be made to participants in cash, Common Stock, restricted Common Stock, other property or a combination of the foregoing as determined by the Committee.

In the event an officer or employee terminates employment due to death, total disability or retirement after completing at least one month of the Performance Period for an award, such officer or employee shall be entitled to a pro rata portion of the award if the applicable performance goals are met. Unless the Committee provides otherwise, if an officer or employee terminates employment for any other reason prior to the end of a Performance Period for an award, he shall not be entitled to any payment under the award.

Performance Criteria

Payments under, or vesting of, awards under the 2005 Plan may be subject to the attainment of performance goals established by the Committee. Performance goals may be based on financial or operating measures of the Company or its divisions, such as pretax income, net income, earnings per share, sales volume, revenue, expenses, return on assets, return on equity, return on investment, net profit margin, operating profit margin, cash flow, total stockholder return, capitalization, liquidity, reserve adds or replacement, finding and development costs, production volume, results of customer satisfaction surveys and other measures of quality, safety, productivity, cost management or process improvement. The criteria may be based on the Company's performance compared with one or more selected companies.

Deferral of Payment

Subject to the terms of the Company's Executive Deferred Compensation Plan (the "EDCP") and applicable law, an officer or employee eligible to participate in the EDCP may defer the receipt of some or all of the cash or Common Stock receivable pursuant to an award under the 2005 Plan. Subject to the terms of the Company's Deferred Compensation Plan for Non-Employee Directors and applicable law, a non-employee director may defer the receipt of some or all of the cash or Common Stock receivable pursuant to an award under the 2005 Plan.

Transferability

Except for certain transfers of options to family members approved by the Committee, no award under the 2005 Plan shall be transferable other than by will or the laws of descent and distribution. Any option or SAR shall be exercisable (a) during the lifetime of the grantee, only by the grantee or, to the extent permitted by the Code, by an appointed guardian or legal representative of the grantee, and (b) after death of the grantee, only by the grantee's legal representative or by the person who acquired the right to exercise such option or SAR by bequest or inheritance or by reason of the death of the grantee.

Amendment

The Board may at any time terminate or amend the 2005 Plan in any respect, except that the Board may not, without further approval of the Stockholders, amend the 2005 Plan in a manner that requires such approval under the rules of the NYSE, the Code, or any other applicable law, including any amendment that materially increases the maximum number of shares of Common Stock issuable under the 2005 Plan or results in the repricing of options. No

amendment or termination of the 2005 Plan may, without the consent of an affected participant, alter or impair any of the rights or obligations under any award granted to such participant under the 2005 Plan.

Change in Control

In the event of a change in control, any outstanding options or SARs that have not yet vested shall vest effective as of such date, restrictions on restricted stock shall lapse, and participants who have previously been granted performance awards shall earn the amounts the participants would have earned if target performance under the awards was obtained.

A change in control occurs (a) upon a change in any two-year period in a majority of the members of the Board of Directors of the Company, as defined in the 2005 Plan, (b) if any person becomes the beneficial owner, directly or indirectly, of 25% or more of the Company's outstanding Common Stock, (c) upon the consummation of a merger or consolidation of the Company with any other corporation, a sale of 50% or more of the Company's assets, liquidation or dissolution of the Company or combination of the foregoing transactions ("Transactions") other than a Transaction immediately following which the Stockholders of the Company and any trustee or fiduciary of any Company employee benefit plan immediately prior to the Transaction own at least 60% of the voting power of the surviving corporation(s), or (d) if a majority of the members of the Board of Directors in office immediately prior to a proposed transaction determine by written resolution that such proposed transaction, if taken, will be deemed a change in control and such proposed transaction is effected.

Federal Income Tax Effects

The federal income tax consequences applicable to the Company and grantees in connection with awards under the 2005 Plan are complex and depend, in large part, on the surrounding facts and circumstances. Under current federal income tax laws, a participant will generally recognize income, and the Company will be entitled to a deduction, with respect to grants of performance awards, options, SARs, and restricted stock as follows:

(A) Payments in Respect of Performance Awards.Any cash and/or the fair market value of any Common Stock received as payments in respect of performance awards under the 2005 Plan will constitute ordinary income to the officer or employee in the year in which paid, and the Company will be entitled to a deduction in the same amount.

(B) Incentive Stock Options.The grant of an Incentive Stock Option will not result in any immediate tax consequences to the Company or the optionee. An optionee will not realize taxable income, and the Company will not be entitled to any deduction, upon the timely exercise of an Incentive Stock Option, but the excess of the fair market value of the Common Stock acquired over the exercise price will be an item of tax preference for purposes of the alternative minimum tax. If the optionee does not dispose of the Common Stock acquired within one year after its receipt (or within two years after the date the option was granted), the gain or loss realized on the subsequent disposition of the Common Stock will be treated as long-term capital gain or loss and the Company will not be entitled to any deduction. If the optionee disposes of the Common Stock acquired less than one year after its receipt (or within two years after the option was granted), the optionee will realize ordinary income in an amount equal to the lesser of (i) the excess of the fair market value of the Common Stock acquired on the date of exercise over the exercise price, or (ii) if the disposition is a taxable sale or exchange, the amount of any gain realized. Upon such a disqualifying disposition, the Company will be entitled to a deduction in the same amount and at the same time as the optionee realizes such ordinary income. Any amount realized by the optionee in excess of the fair market value of the Common Stock on the date of exercise will be taxed to the optionee as capital gain.

(C) Nonqualified Stock Options.The grant of a Nonqualified Stock Option will not result in any immediate tax consequences to the Company or the optionee. Upon the exercise of a Nonqualified Stock Option, the optionee will generally realize ordinary income equal to the excess of the fair market value of the Common Stock acquired over

the exercise price. The Company will be entitled to a deduction at the same time as, and in an amount equal to, the income realized by the optionee.

(D) Stock Appreciation Rights.Upon the exercise of any SAR, any cash received will constitute ordinary income to the grantee. The Company will be entitled to a deduction in the same amount and at the same time.

(E) Restricted Stock.A grantee generally will not realize taxable income upon an award of restricted stock. However, a grantee who receives restricted stock, either as a grant or in payment of a performance award, will realize as ordinary income at the time of the lapse of the restrictions an amount equal to the fair market value of the Common Stock at the time of such lapse. Alternatively, a grantee may elect to realize ordinary income on the date of receipt of the restricted Common Stock. At the time the grantee realizes ordinary income, the Company will be entitled to deduct the same amount as the ordinary income realized by the grantee.

(F) Internal Revenue Code Section 162(m).Under Section 162(m) of the Internal Revenue Code, the allowable federal income tax deduction by the Company for compensation paid to certain of its executive officers is limited to $1 million per year per officer. "Performance-based compensation" is generally excluded from this deduction limit. Payments or grants (excluding grants of restricted stock that vest solely upon the passage of time) under the 2005 Plan are intended to qualify as performance- based compensation under Section 162(m) and the applicable regulations, which require the 2005 Plan to be approved by Stockholders.

(G) Code Section 409A.To the extent that any award under the 2005 Plan is or may be considered to involve a nonqualified deferred compensation plan or deferral subject to Code Section 409A, the terms and administration of such award shall comply with the provisions of such section, applicable IRS guidance and good faith reasonable interpretations thereof and, to the extent necessary, such award shall be modified, replaced, or terminated in the discretion of the Committee.

Burn Rate and New Plan Benefits

The Company's average annual burn rate, which is the total number of equity awards granted in a given year divided by the number of common shares outstanding, for 2002 through 2004 is 1.87%. As described above, the selection of officers, employees and non-employee directors who will receive awards under the 2005 Plan, if it is approved by the Stockholders, and the size and types of awards will be determined by the Committee in its discretion. No awards have been made under the 2005 Plan and the amount of any such awards under the 2005 Plan is not yet determinable due to vesting, performance and other requirements; therefore, it is not possible to predict the benefits or amounts that will be received by, or allocated to, particular individuals or groups of employees in 2005. The following table sets forth the awards, including options, restricted stock and performance units, that were granted under the 2002 Plan in 2004 to the individuals and groups indicated.

Item No. 4
STOCKHOLDER PROPOSAL REQUESTING
ESTABLISHMENT OF AN OFFICE OF THE BOARD OF DIRECTORS

The following proposal was submitted to the Company by New York City Comptroller William C. Thompson, Jr., as custodian and trustee for, and on behalf of, the New York City Employees' Retirement System, the New York City Teachers' Retirement System, the New York City Police Pension Fund and the New York City Fire Department Pension Fund, and as custodian of the New York City Board of Education Retirement System which held, collectively, 377,185 shares of the Company's Common Stock as of February 11, 2005. Mr. Thompson's address is 1 Centre Street, New York, New York 10007-2341.

Proposal

WHEREAS, the board of directors is meant to be an independent body elected by shareholders and charged by law with the duty and authority to formulate and direct corporate policies; and

WHEREAS, in 2002, the Board of Directors of the New York Stock Exchange, recognizing the need to improve corporate governance, proposed a listing standard to empower non-management directors as a more effective check on management, and to facilitate direct communications between shareholders and the non-management directors; and

WHEREAS, in an August 8, 2003, release pertaining, in part, to disclosure of companies' procedures for shareholder communications with the directors, the Securities and Exchange Commission stated that "Providing security holders with disclosure about the process for communicating with board members would improve the transparency of board operations, as well as security holder understanding of the companies in which they invest;"

WHEREAS, a January 1994 study entitled:Improving Communications Between Corporations and Shareholders: Overall Findings and Recommendations, prepared on behalf of the New Foundations Working Group, John F. Kennedy School of Government, Harvard University, recommended several mechanisms for direct communications between directors and shareholders. Among the recommendations were:

•: Regular meetings with groups of shareholders and selected board members
•: Meetings between large shareholders and the full board of directors

WHEREAS, we believe that the creation of a means for direct communications on corporate governance matters between shareholders and the non-management directors would benefit the company through constructive discussions of perspectives, enhanced understanding, valuable feedback, and the fostering of meaningful links between directors and the shareholders by whom they are elected;

NOW, THEREFORE, BE IT RESOLVED: that the shareholders request the board of directors to establish an Office of the Board of Directors to enable direct communications on corporate governance matters, including meetings, between non-management directors and shareholders. The office shall report directly to a committee of the non-management directors.

Supporting Statement of New York City Comptroller

We believe that the confidence of investors in the U.S. capital markets has been deeply shaken by corporate malfeasance at companies, such as Enron and World Com. As long-term investors, we are concerned about the potential negative impact that continued erosion of investor confidence could have on the long-term interests of the company and the shareholders. This proposal is intended to improve investor confidence by improving director and shareholder communications on corporate governance matters, and strengthening the relationship between the Board of Directors and the shareholders.

Board of Directors' Response Opposing the Stockholder Proposal and
Recommending a Vote "AGAINST" the Stockholder Proposal

Summary

The Board of Directors already has strengthened the communication channels available to the Company's Stockholders and has implemented a number of methods for Stockholders to communicate with the Company and its Directors. According to guidelines provided by the New York Stock Exchange (the "NYSE"), the communication methods already adopted by the Board meet the NYSE's standards for its listed companies. The Board of Directors believes the method urged by the proponent does not add to, and may detract from, the Board's current communication system. As a result, the Board of Directors unanimously recommends a vote "AGAINST" the Proposal.

The Board Already Has Implemented Multiple Channels for Communication

As discussed on Page of this Proxy Statement, the Board, including all of its non-management Directors, already has implemented multiple methods for communicating with non-management Directors. Recognizing that Stockholders are a diverse group and desiring to accommodate their varied practices, the communication channels already in place are varied and include:

•: Stockholders wishing to communicate with one or more Directors may do so in a writing addressed to the Director(s) and sent in care of the Corporate Secretary.
•: Stockholders may communicate with Directors by e-mail addressed tokerr-mcgeedirectors@kmg.com.
•: Stockholders may use the Company's toll-free hotline to anonymously and confidentially report to the Audit Committee complaints regarding accounting, internal accounting controls or auditing matters and to make any other kind of report to non-management Directors.

The NYSE requires companies to disclose a means for direct communications between Stockholders and non-management Directors. The NYSE has expressed its approval for a communications method, such as that provided by the Company, that uses the Corporate Secretary's office to compile, organize and forward relevant communications.

Implementation of the Proposal Would Not Improve Existing Communication Methods and May Be Counterproductive.

The Board of Directors believes that implementation of the Proposal would not improve existing communications methods. If the Company were to form a separate Office of the Board, that office likely would be staffed by the Corporate Secretary, who would be instructed to route communications to non-management Directors in the same way as the same Corporate Secretary currently routes those communications. Also, non-management Directors already can meet with Stockholders when they deem appropriate.

The Board of Directors also believes that implementation of the Proposal could be counterproductive in several respects. These include:

•: A separate Office of the Board would add a layer of administrative formality and complexity without corresponding benefit.
•: Stockholders might perceive the Office of the Board to have more authority than it legally can have and might fail to take advantage of more direct means of communication which already are provided.
•: Stockholders might misperceive that the Board had established a separate office in order to provide special benefits to Directors unrelated to communications with Stockholders.

Conclusion

The Board already has implemented multiple methods for Stockholders to communicate with the Company's non-management Directors. The methods adopted by the Board are varied in type and satisfy the rules adopted by the NYSE. Implementation of the Proposal would result in changes or additions to the Board's current communication system that increase administrative burdens without providing corresponding benefits and might undercut the existing system in important ways. Accordingly, the Board of Directors unanimously opposes the Proposal.

Recommendation of the Board of Directors

The Board unanimously recommends that Stockholders vote "AGAINST" the Proposal.

REPORT OF THE EXECUTIVE COMPENSATION COMMITTEE

The Executive Compensation Committee (the "Committee") seeks to provide competitive levels of total compensation for the Company's key executives through a mix of base salary, annual incentive pay, long term incentives and other benefits. The Committee believes that incentive or "at risk" compensation is a key ingredient in motivating executive performance to maximize stockholder value and align executive performance with Company objectives and stockholder interests. The Committee targets total compensation to be within range of the 75^th percentile of a peer group of comparable energy and chemical companies selected with the assistance of an independent consulting firm to be representative of the Company's size and business activities (the "Comparison Group"). Members of the Comparison Group are comparably-sized companies in the same industries as Kerr-McGee. Since a substantial amount of the Company's business is conducted outside the United States, its compensation policies must also be internationally competitive and flexible. This enables the Company to attract and retain high quality management and to compete globally.

Base Salaries

In setting the Chief Executive Officer's base salary and reviewing base salaries for other executive officers, the Committee annually reviews competitive market compensation data of the Comparison Group prepared by an independent consulting firm retained by the Committee. The Committee sets the Chief Executive Officer's base salary and recommends that other executive officers' base salaries be targeted within range of the 75^th percentile of base salaries of like executives in the Comparison Group to enable the Company to attract and retain key executives. The Committee takes into consideration individual performance, based on the Committee's evaluation of the performance of the Chief Executive Officer and the Chief Executive Officer's evaluation of the performance of other executive officers, when determining and reviewing salaries.

Annual Incentive Compensation

Through its Annual Incentive Compensation Plan (the "AICP"), the Company compensates its officers with cash bonuses based on the Company's performance. Each year, a target is established for each executive officer's AICP award. The target AICP award, set within range of the 75^th percentile of similar awards of the Comparison Group, is based on the officer's level of responsibility. In 2004, target awards ranged from 60% to 125% of base salary.

The maximum amount of an executive officer's AICP award is determined by the Company's performance with respect to certain objective measures. Minimum performance thresholds established annually by the Committee must be achieved before officers qualify for any portion of their targeted AICP awards. An officer may receive up to 200% of the officer's target award if targeted performance objectives are exceeded. Additionally, the amount of an officer's AICP award may be reduced or eliminated based on the officer's individual performance. Actual AICP awards for 2004 were 127% of targeted awards.

Awards for 2004, set forth in the Summary Compensation Table on Page , were based on the performance of the Company's operating divisions, as compared to the Company's approved budget, and each executive's individual contribution toward the Company's overall success. The maximum amount for each AICP award was derived from eight measurement criteria—four measurement criteria for the Company's oil and gas business, which account for 70% of the maximum AICP award, and four measurement criteria for the Company's chemical business, which account for 30% of the maximum AICP award.

The four measurement criteria for the Company's oil and gas business for 2004 were: (1) Production Cash Flow Per BOE—measuring how much cash flow is generated for the Company from each barrel of oil equivalent sold, as compared to budget (weighted 40% of the oil and gas component of the AICP award); (2) Production Volume—measuring the barrels of oil equivalent produced over the prior year, as compared to budget (weighted 20%); (3) Production Replacement Rate—measuring how effectively the Company replaces production with new reserves, as compared to budget

(weighted 20%); and (4) Unit Finding and Development Costs—measuring how cost effectively the Company finds and develops oil and gas reserves, as compared to budget (weighted 20%).

The four measurement criteria for the Company's chemical business for 2004 were: (1) Cash Flow Return on Average Capital Employed, as compared to budget (weighted 40% of the chemical component of the AICP award); (2) Titanium Dioxide Sales Volume, as compared to budget (weighted 20%); (3) Cash Cost per Tonne—measuring the total cash costs to make, sell and deliver each tonne of titanium dioxide, as compared to budget (weighted 20%); and (4) Operating Profit—measuring the amount of profit made on titanium dioxide sales before special items, as compared to budget (weighted 20%).

Long Term Incentives

The Committee believes that ownership of Company stock by the Company's executive officers and Board of Directors promotes commitment to the long term success of the Company. Stock ownership guidelines expressed as a multiple of each officer's base salary (between 100% and 400% of an officer's base salary) or Board members' annual retainer fees (400% of a Director's annual retainer fees) have been established for the Company's executive officers and Board of Directors. The Committee periodically reviews the guidelines and stock ownership levels.

The Stockholders have approved the use of stock options and restricted stock awards, as well as performance units tied to the Company's long term performance, to provide long term incentive compensation for the Company's key executives. The Committee believes that the use of stock based compensation and performance units to establish a direct relationship between the compensation of executives and the value of the Company's stock helps ensure continued alignment between the interests of the executive officers and the interests of the Company and its Stockholders. The Committee believes that equity and performance unit incentives are important tools for attracting and retaining key employees by rewarding long term management performance based on objectively measured results.

The total number of stock options, restricted stock and performance units granted to each executive officer, including the Chief Executive Officer, is based on a percentage of the individual officer's salary. The percentage is set annually by the Committee after considering each officer's performance, level of responsibility, prior awards to the officer and awards made within the Comparison Group. In considering awards made within the Comparison Group, the Committee relies on surveys and reports by an independent consulting firm and targets the 75^th percentile of the Comparison Group. The number of stock options granted in 2004 to Mr. Corbett and the next four highest paid executive officers is set forth in the Option Grants Table on Page . The amount of restricted stock granted in 2004 to Mr. Corbett and the next four highest paid executive officers is set forth in the Summary Compensation Table on Page .

At the beginning of 2004, performance units were issued for the 2004-2006 performance cycle. At the end of 2006, the Company's Total Shareholder Return (shareholder return assuming dividend reinvestment) will be compared to the Total Shareholder Return of the Company's industry peers during the same period, and final award payouts will be made to executive officers based on the Company's rank relative to such peers. The Committee compares the Company's Total Shareholder Return to that of industry peers. This peer group is not adjusted for size in the same way as the Comparison Group because company size is not expected to affect Total Shareholder Return. The number of performance units granted in 2004 to Mr. Corbett and the next four highest paid executive officers is set forth in the Long Term Incentive Plans Table on Page .

Other Benefits

In 2004, executive officers received certain perquisites, including annual stipends provided to facilitate involvement in community activities. Perquisites that meet reporting thresholds are reflected in the Executive Compensation table on page under Other Annual Compensation. Officers periodically receive mementos in connection with meetings of the Board. Taxes payable on such items are paid by the Company and totaled less than $1,100 per person in 2004. The Committee periodically reviews perquisites

and, in consultation with the independent consulting firm, has determined they are consistent with the Committee's executive compensation policy and market practices.

Compensation of the Chief Executive Officer

The Committee determines the Chief Executive Officer's compensation in accordance with the policies described above. In determining Mr. Corbett's base salary, the Committee considers competitive salaries of chief executive officers within the Comparison Group as compiled by an independent consulting firm.

Mr. Corbett's incentive compensation under the AICP for 2004, which was 127% of his targeted award and is set forth in the Summary Compensation Table on Page , was based on the eight measurement criteria described in this report, using the same weightings as discussed above for the AICP awards of other executive officers, and his individual contribution toward the Company's overall success. Individual factors considered by the Committee include Mr. Corbett's role in executing the Company's acquisition of Westport Resources Corporation, which added depth, breadth and balance to the Company's oil and gas operations, increasing proved reserves by nearly 30% and expanding high-margin production and low-risk exploitation opportunities; reducing the Company's debt to equity ratio from 58% to 41% in 2004; achieving initial production at the Company's Red Hawk, Bohai Bay and James developments on or ahead of schedule and within budget; identifying new development opportunities; identifying and rationalizing non-core assets and businesses; developing current managers and potential management candidates; and planning for executive succession. Mr. Corbett's total direct compensation for 2004 is above the 75^th percentile of the Comparison Group.

Having considered the various elements of the compensation of the Chief Executive Officer and the Company's other executive officers, the Committee believes that executive compensation arrangements for 2004 appropriately reflect its policy to set executive compensation so that the interests of the Company's executive officers are aligned with the interests of the Company's Stockholders.

Federal Income Tax Deductibility

Section 162(m) of the Internal Revenue Code limits the corporate deduction on compensation paid to the Chief Executive Officer and to the next four highest paid officers to $1 million each during any fiscal year. To the extent that compensation is based upon the attainment of performance goals set by the Committee pursuant to plans approved by the Company's Stockholders, the compensation is not included in the computation of the $1 million limit. The Committee considers the impact of Section 162(m) when making compensation decisions and attempts to preserve the tax deductibility of executive compensation when doing so is consistent with the Committee's overall compensation philosophy and in the Company's best interest. However, the Committee may award nondeductible compensation when it believes that such awards are in the Company's best interest, balancing short term tax efficiency with the Company's long term strategic objectives.

STOCK OPTIONS

The following table contains information concerning stock options granted during the fiscal year ended December 31, 2004, to the named executive officers.

OPTION GRANTS IN LAST FISCAL YEAR

Name	No. of Securities Underlying Options Granted(1)	Percent of Total Options Granted to Employees in Fiscal Year 2004		Per Share Exercise Price		Expiration Date	Grant Date Present Value(2)
Luke R. Corbett	125,200	9.25	%	$	49.45	January 13, 2014	$	1,075,401
Kenneth W. Crouch	47,500	3.51	%		49.45	January 13, 2014		408,000
Robert M. Wohleber	37,150	2.74	%		49.45	January 13, 2014		319,099
David A. Hager	25,100	1.85	%		49.45	January 13, 2014		215,596
Gregory F. Pilcher	20,250	1.50	%		49.45	January 13, 2014		173,937

(1): All stock options granted in 2004 were nonqualified stock options. The exercise price per option is 100% of the fair-market value of a share of Common Stock on the date of grant. No option expires more than ten years and one day from the date of grant.
(2): The present value of stock option grants was computed in accordance with the Black-Scholes option pricing model, with assumptions consistent with Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based Compensation," as permitted by the rules of the Securities and Exchange Commission. Key assumptions used under the Black-Scholes model include: (a) an expected option term of 5.8 years, (b) interest rate of 3.48%, which represents the U.S. Treasury Strip Rate on January 13, 2004, with maturity corresponding to the expected option term, (c) stock price volatility of 22.59%, calculated using monthly stock prices for the 36 months prior to the dates of the grant, and (d) dividends at an average annual dividend yield of 3.55%. Based on the Black-Scholes model, the value on January 13, 2004, was $8.59 per option. The Company's use of the Black-Scholes model should not be construed as an endorsement of its accuracy at valuing options. All stock option valuation models, including the Black-Scholes model, require a prediction about the future movement of the stock price. The real value of the options in this table depends upon the actual changes in the market price of the Company's common stock during the applicable period.

Covered compensation under the retirement plans consists of salary, bonus and pretax Section 125 and 401(k) benefit contributions, all based on the highest 36 consecutive months out of the last 120 months prior to retirement. Amounts shown are computed on a straight life annuity basis. As of December 31, 2004, Mr. Corbett had 19 years of credited service; Mr. Crouch, 30; Mr. Wohleber, 5; Mr. Hager, 23; and Mr. Pilcher, 12.

The Company's Supplemental Executive Retirement Plan (the "SERP"), adopted effective January 1, 1991, is a defined benefit plan administered by the Executive Compensation Committee. The SERP, as amended, provides supplemental retirement benefits to certain key senior executives selected by the Executive Compensation Committee. Mr. Hager was a beneficiary of the Executive Retirement Plan of Oryx Energy Company ("Oryx") prior to Oryx's merger with the Company, and, accordingly, certain of his benefits under the SERP continue to be determined in accordance with the provisions of the Oryx plan. With respect to all participants, full benefits are payable upon retirement on or after age 60, and reduced benefits are payable upon retirement on or after age 52. SERP benefits are paid in an actuarially determined lump sum calculated to approximate a life annuity. The amount of the benefit is equal to a portion of the participant's final average monthly compensation less the sum of (1) the participant's monthly primary social security benefit (in the case of Mr. Hager, up to 30% of monthly primary social security benefit) and (2) the participant's monthly benefits payable under the Company's other defined benefit plans. The portion of a participant's final average monthly compensation used to determine SERP benefits varies from 40% to 70% and depends on

the participant's age at retirement and other factors. As of December 31, 2004, the estimated lump sum SERP benefit payable upon retirement to the executive officers named in the Summary Compensation Table, assuming (i) retirement at age 60 (retirement on December 31, 2004 for Mr. Crouch as he is older than 60), and (ii) salaries are maintained at their current level, is: Mr. Corbett, $12,550,728; Mr. Crouch, $2,117,472; Mr. Wohleber, $2,419,331; Mr. Hager, $691,813; and Mr. Pilcher, $1,147,803. The estimates do not include increases in base compensation or payments of cash bonuses after December 31, 2004, and are based on an interest rate of 6.5%. Cash bonuses paid in February 2005 do not affect the estimates described above.

CONTINUITY AGREEMENTS

Continuity Agreements between the Company and its executive officers and certain key employees, including Messrs. Corbett, Crouch, Hager, Wohleber and Pilcher, provide certain benefits in the event of a qualifying termination that occurs in connection with a "change in control" of the Company.

In the event of a qualifying termination of employment within two years after a change in control, such executive will be entitled to receive:

•: A lump sum cash payment equal to three times the executive's annual base salary, bonuses and perquisites (with such perquisites calculated at 7% of the executive's annual base salary);
•: Any accrued but unpaid compensation (including the pro-rata amount of any bonus); and
•: An amount representing additional savings plan contributions for a three-year period plus the present value of lost pension benefits under the Company's qualified defined benefit pension plans after giving effect to five years of credit for age and service in the benefit calculation.

If the payment made to the officer causes the officer to be subject to an excise tax because the payment is a "parachute payment" (as defined in the Internal Revenue Code), then the payment shall be increased to compensate the executive for the excise tax. In addition, in the event of a qualifying termination, the officer will be entitled to:

•: A continuation of welfare benefits for up to three years;
•: Outplacement services;
•: Acceleration of vesting of all equity and equity-based awards; and
•: Amounts that such officer would otherwise be entitled to receive under Kerr-McGee's Supplemental Executive Retirement Plan (SERP) described more fully in the "Retirement Plans."

A change in control means (a) a change in any two-year period in a majority of the members of the Board of the Company, as defined in the Continuity Agreement, (b) any person becoming the beneficial owner, directly or indirectly, of 25% or more of the Company's outstanding Common Stock, (c) with certain exceptions, the consummation of a merger or consolidation of the Company with any other corporation, a sale of 50% or more of the Company's assets, liquidation or dissolution of the Company or combination of the foregoing transactions other than such a transaction immediately following which the stockholders of the Company and any trustee or fiduciary of any Company employee benefit plan immediately prior to the transaction own at least 60% of the voting power of the surviving corporation(s), or (d) if a majority of the members of the Board in office immediately prior to a proposed transaction determine by written resolution that such proposed transaction, if taken, will be deemed a change in control and such proposed transaction is effected.

The Company also has made provision under its Benefits Restoration Plan and the SERP for the crediting of additional years of age and service to certain executive officers, including the named executive officers, whose employment is terminated under the circumstances described above following a change in control of the Company.

Article III

Administration

3.1 The Committee. The Plan shall be administered by the Committee. Subject to such approvals and other authority as the Board may reserve to itself from time to time, the Committee shall, consistent with the provisions of the Plan, from time to time establish such rules and regulations and appoint such agents as it deems appropriate for the proper administration of the Plan, and make such determinations under, and such interpretations of, and take such steps in connection with the Plan or the Awards as it deems necessary or advisable.

3.2 Authority of the Committee. Subject to the provisions herein, the Committee shall have the full power (a) to determine the Employees and Non-Employee Directors who shall receive Awards under the Plan, (b) to determine the size and types of Awards to be issued under the Plan, (c) to determine the terms and conditions of such Awards in a manner consistent with the Plan, (d) to construe and interpret the Plan and any agreement or instrument entered into under the Plan, and resolve any ambiguities with respect to any of the terms and provisions hereof as written and as applied to the operation of the Plan, (e) to establish, amend or waive rules and regulations for the Plan's administration, and (f) to amend the terms and conditions of any outstanding Award to the extent such terms and conditions are within the sole discretion of the Committee as provided in the Plan and subject to the limitations and restrictions otherwise applicable under the Plan, including those contained in Article XIII which among other restrictions prohibit the repricing of options without further shareholder approval. Notwithstanding the foregoing, the Committee shall not amend an Award in a manner that would have a materially adverse effect on the grantee's rights or obligations under the Award without the consent of the grantee.

The Committee may take any action consistent with the terms of the Plan which the Committee deems necessary to comply with any laws or regulatory requirements of a foreign country or to avoid adverse tax consequences under any such law or requirements. Such actions may include modifying the terms and conditions governing any Awards, including issuing restricted stock units in lieu of Restricted Stock, or establishing any local country plans as sub-plans to this Plan, each of which may be attached as an appendix hereto.

As permitted by law, the Committee may delegate its authority hereunder, including without limitation delegating to a Company officer the authority to issue Awards covering a specified number of shares of Stock to Employees who are not officers.

3.3 Decisions Binding. All determinations and decisions of the Committee as to any disputed question arising under the Plan or an Award, including questions of construction and interpretation, shall be final, binding and conclusive upon all parties.

3.4 Awards Subject to Performance Goals. The Committee may determine that an Award shall be subject to the satisfaction of such performance goals as established by the Committee. As determined by the Committee, achievement of the performance goals may be measured (a) individually, alternatively or in any combination, (b) with respect to the Company, a subsidiary, division, business unit, product line, product, or any combination of the foregoing, or (c) on an absolute basis, or relative to a target, to a designated comparison group, to results in other periods, to an index, or to other external measures.

In determining whether a performance goal is met, the Committee may exclude the impact of any event or occurrence which the Committee determines should appropriately be excluded, such as a restructuring or other nonrecurring charge, an event either not directly related to the operations of the

Company or not within the reasonable control of the Company's management, or a change in accounting standards required by U. S. generally accepted accounting principles.

For an Award that is subject to performance goals and that is intended to qualify as "performance-based compensation" under Section 162(m) of the Code, the following additional provisions shall apply: (a) the applicable performance goals will be based on one or more Indicators of Performance, (b) the Committee may adjust downwards, but not upwards, the amount payable pursuant to such Award upon attainment of the performance goals, (c) the Committee may not waive the achievement of the applicable performance goals except in the case of the death or disability of the grantee, or under such other conditions where such waiver will not jeopardize the treatment of other Awards as "performance-based compensation" under Section 162(m), and (d) the Award shall otherwise comply with the requirements of Section 162(m), or any successor provision thereto, and the regulations thereunder.

3.5 Effect of Code Section 409A. To the extent that any Award under this plan is or may be considered to involve a nonqualified deferred compensation plan or deferral subject to Section 409A of the Code, the terms and administration of such Award shall comply with the provisions of such Section, applicable IRS guidance and good faith reasonable interpretations thereof and, to the extent necessary, shall be modified, replaced, or terminated in the discretion of the Committee.

The Stock to be distributed under the Plan may be either authorized and issued shares or unissued shares, including but not limited to shares held as treasury shares. The maximum number of shares of Stock which may be issued under the Plan shall not exceed, in the aggregate, 10 million (10,000,000). The following additional limitations shall apply to the issuance of Stock under the Plan pursuant to various types of Awards:

	Type of Awards	Maximum Issuance

Article VI

Stock Options

6.1 Grant of Options.

(a) The Committee may, at any time and from time to time, grant Options under the Plan to eligible Employees or Non-Employee Directors, for such numbers of shares and having such terms as the Committee shall designate, subject to the provisions of the Plan. The Committee will also determine the type of Option granted (e.g., ISO, nonstatutory, other statutory Options as from time to time may be permitted by the Code) or a combination of various types of Options. The date on which an Option shall be granted shall be the date of the Committee's authorization of such grant. Any individual at any one time and from time to time may hold more than one Option granted under the Plan or under any other Stock plan of the Company.

(b) Each Option shall be evidenced by a Stock Option Agreement in such form and containing such provisions consistent with the provisions of the Plan as the Committee from time to time shall approve.

6.2 Exercise Price. The price at which shares of Stock may be purchased under an Option shall not be less than 100% of the Fair Market Value of the Stock on the date the Option is granted.

6.3 Option Period. The period during which an Option may be exercised shall be determined by the Committee; provided, that such period will not be longer than ten years from the date on which the Option is granted in the case of ISOs, and ten years and one day in the case of other Options. The date or dates on which portion(s) of an Option may be exercised during the term of an Option shall be determined by the Committee and may vary from Option to Option. The Committee may also determine to accelerate the time at which portion(s) of an outstanding Option may be exercised.

6.4 Termination of Service. An Option shall terminate and may no longer be exercised three months after the Optionee ceases to be an Employee for any reason other than termination for Cause, Total Disability, death or Retirement. Unless an Employee's Stock Option Agreement provides otherwise, all Options shall terminate and may no longer be exercised upon an Optionee's termination for Cause. If an Employee's employment is terminated by reason of Total Disability or Retirement, all Options held by the Employee will vest and may be exercised within the period not to exceed the lesser of four years following such termination or the remaining term of the Option award. If the Optionee is an Employee and dies while in the employ of the Company, a Subsidiary or LLC, the vesting provisions of an Option held by the Employee will lapse and such Option may, within the lesser of four years after the Optionee's death or the remaining term of the Option award, be exercised by the legal representative of the Optionee's estate, or if it has been distributed as part of the estate, by the person or persons to whom the Optionee's rights under the Option shall pass by will or by the applicable laws of descent and distribution. If a Non-Employee Director's service is terminated due to Retirement or Total Disability, all Options held by the Non-Employee Director will vest and such Options may be exercised within the remainder of the Option's term. If a Non-Employee Director dies while in the service of the Company, all Options held by the Non-Employee Director will vest and such Options may be exercised within the remainder of the term of the Option by the legal representative of the Optionee's estate, or if it has been distributed as part of the estate, by the person or persons to whom the Optionee's rights under the Option shall pass by will or by the applicable laws of descent and distribution. In no event may an Option be exercised to any extent by anyone after the expiration or termination of the Option.

6.5 Payment for Shares.

To the extent permitted under applicable law and the relevant Stock Option Agreement, the exercise price of an Option shall be paid to the Company in full at the time of exercise at the election of the Optionee (1) in cash, (2) in shares of Stock having a Fair Market Value equal to the aggregate exercise price of the Option and satisfying such other requirements as may be imposed by the Committee, (3) partly in cash and partly in such shares of Stock, (4) to the extent permitted by the Committee, through the withholding of shares of Stock (which would otherwise be delivered to the Optionee) with an aggregate Fair Market Value on the exercise date equal to the aggregate exercise price of the Option or (5) through the delivery of irrevocable instructions to a broker to deliver promptly to the Company an amount equal to the aggregate exercise price of the Option. The Committee may limit the extent to which shares of Stock may be used in exercising Options. No Optionee shall have any rights to dividends or other rights of a stockholder with respect to shares of Stock subject to an Option until the Optionee has given written notice of exercise of the Option, paid in full for such shares of Stock and, if applicable, has satisfied any other conditions imposed by the Committee pursuant to the Plan.

Article VII

Stock Appreciation Rights

7.1 Grant. An SAR shall represent a right to receive a payment in cash equal to the excess of the Fair Market Value of a specified number of shares of Stock on the date the SAR is exercised over an amount (the SAR exercise price) which shall be no less than the Fair Market Value of the shares on the date the SAR was granted (or the option price for SARs granted in tandem with an Option), as set forth in the applicable Award agreement. Each SAR shall be evidenced by an Award agreement that shall specify the SAR exercise price, the duration of the SAR, the number of shares of stock to which the SAR pertains, whether the SAR is granted in tandem with the grant of an Option or is freestanding, and such other provisions as the Committee shall determine. SARs shall be exercisable at such times and be subject to such restrictions and conditions as the Committee shall in each instance approve and which shall be set forth in the applicable Award agreement, which need not be the same for each grant of for each grantee.

7.2 Exercise. SARs granted in tandem with the grant of an Option may be exercised for all or part of the shares of Stock subject to the related Option upon the surrender of the right to exercise the equivalent portion of the related Option. SARs granted in tandem with the grant of an Option may be exercised only with respect to the shares of Stock for which its related Option is then exercisable. SARs granted independently from the grant of an Option may be exercised upon the terms and conditions contained in the applicable Award agreement.

7.3 Termination. The Award agreement for a SAR shall set forth the extent to which a grantee shall have the right to exercise an SAR following termination of the grantee's service. Such provisions shall be determined in the sole discretion of the Committee, need not be uniform among all SARs, and may reflect distinctions based on the reasons for termination.

Article VIII

Restricted Stock

8.1 Terms of Grant. At the time of making a grant of Restricted Stock or making payment of an Award in Restricted Stock to an Employee or Non-Employee Director, the Committee shall establish a Restriction Period and assign such terms, conditions and other restrictions to the Restricted Stock as it shall determine.

8.2 Restricted Stock—Rights. Restricted Stock will be represented by a Stock certificate registered in the name of the Restricted Stock recipient. Such certificate, accompanied by a separate duly endorsed stock power, shall be deposited with the Company. The recipient shall be entitled to receive dividends during the Restriction Period and shall have the right to vote such Restricted Stock and all other stockholder's rights, with the exception that (i) the recipient will not be entitled to delivery of the Stock certificate during the Restriction Period, (ii) the Company will retain custody of the Restricted Stock during the Restriction Period and (iii) a breach of the terms and conditions established by the Committee pursuant to the Award will cause a forfeiture of the Restricted Stock. The Committee may, in addition, prescribe additional restrictions, terms and conditions upon or to the Restricted Stock.

8.3 Termination of Service. If an Employee or Non-Employee Director terminates service by reason of Total Disability, death or Retirement prior to the expiration of a Restriction Period for a grant of Restricted Stock, the Restriction Period will lapse and the shares will be delivered to the recipient. Unless the Committee provides otherwise, a termination of service for other reasons prior to the expiration of the applicable Restriction Period will result in the forfeiture of the Restricted Stock.

8.4 Restricted Stock Agreement. Each grant of, or payment of an Award in, Restricted Stock shall be evidenced by a Restricted Stock Agreement in such form and containing such terms and conditions not inconsistent with the provisions of the Plan as the Committee from time to time shall approve.

Article IX

Performance Awards

9.1 Eligibility for Awards. The Committee shall designate Employees as eligible to receive Performance Awards under the Plan and shall establish applicable Performance Periods and performance goals for any such Awards.

9.2 Performance Awards. Performance Awards may be in the form of performance shares, which are units valued by reference to shares of Stock or performance units, which are units valued by reference to financial measures or property other than Stock, and shall be subject to such terms and conditions and other restrictions as the Committee shall assign. At the time of making grants of Performance Awards, the Committee shall establish such terms and conditions as it shall determine applicable to such Awards. Performance Awards may be paid out in cash, Stock, Restricted Stock, other property or a combination thereof. Recipients of Performance Awards are not required to provide consideration other than the rendering of service.

9.3 Partial Performance Period Participation. Subject to applicable restrictions under Section 162(m) of the Code, the Committee shall determine the extent to which an Employee shall participate in a partial Performance Period because of becoming eligible after the beginning of such Performance Period. In the event an Employee terminates employment due to death, Total Disability or Retirement after completing at least one month of the Performance Period for an Award, such Employee shall be entitled to a pro rata portion of the Award if the applicable performance goals are met, payable in accordance with procedures established by the Committee. Unless the Committee provides otherwise, if an Employee terminates employment for any other reason prior to the end of a Performance Period for an Award, he shall not be entitled to any payment under the Award.

Article X

Adjustment Upon Changes In Stock

Subject to the limitations of Article XIII, the Committee shall appropriately adjust the number of shares or kind of Stock which may be issued pursuant to this Plan, the other limits on Stock issuable under the Plan under Article V, and the number of shares covered by, and the exercise price of, each outstanding Award, for any increase or decrease in the total number of issued and outstanding Stock

(or change in kind) resulting from any change in the Stock through a merger, consolidation, reorganization, recapitalization, subdivision or consolidation of shares or other capital adjustment or the payment of a stock dividend or other increase or decrease (or change in kind) in such shares. In the event of any such adjustment, fractional shares shall be eliminated.

Article XI

Change In Control

Notwithstanding anything to the contrary in the Plan, in the event of a Change in Control:

(i) If during a Restriction Period(s) applicable to Restricted Stock issued under the Plan, all restrictions imposed hereunder on such Restricted Stock shall lapse effective as of the date of the Change in Control;

(ii) If during a Performance Period(s) applicable to a Performance Award granted under the Plan, an Employee shall earn the number of performance shares or performance units which the Employee would have earned as if target performance under the Award was obtained; and

(iii) Any outstanding Options or SARs that are not exercisable shall become exercisable effective as of the date of a Change in Control. If a grantee's employment or service is terminated within 24 months of the effective date of a Change in Control, to the extent that any Option or SAR was exercisable at the time of the grantee's termination, such Option or SAR may be exercised within four years following the date of termination or expiration of the Award if sooner.

For purposes of the Plan, a "Change in Control" shall be deemed to have occurred if:

(a) Any person ("Person") as defined in Section 3(a)(9) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and as used in Section 13(d) and 14(d) thereof, including a "group" as defined in Section 13(d) of the Exchange Act, but excluding the Company and any subsidiary and any employee benefit plan sponsored or maintained by the Company or any subsidiary (including any trustee of such plan acting as trustee), directly or indirectly, becomes the "beneficial owner" (as defined in Rule 13d-3 under the Exchange Act), of securities of the Company representing 25% or more of the combined voting power of the Company's then outstanding securities (other than indirectly as a result of the Company's redemption of its securities); or

(b) The consummation of any merger or other business combination of the Company, sale of 50% or more of the Company's assets, liquidation or dissolution of the Company or combination of the foregoing transactions (the "Transactions") other than a Transaction immediately following which the shareholder of the Company and any trustee or fiduciary of any Company employee benefit plan immediately prior to the Transaction own at least 60% of the voting power, directly or indirectly, of (A) the surviving corporation in any such merger or other business combination; (B) the purchaser or successor to the Company's assets; (C) both the surviving corporation and the purchaser in the event of any combination of Transactions; or (D) the parent company owning 100% of such surviving corporation, purchaser or both the surviving corporation and the purchaser, as the case may be; or

(c) Within any twenty-four month period, the persons who were directors immediately before the beginning of such period (the "Incumbent Directors") shall cease (for any reason other than death) to constitute at least a majority of the Board or the board of directors of a successor to the Company. For this purpose, any director who was not a director at the beginning of such period shall be deemed to be an Incumbent Director if such director was elected to the Board by, or on the recommendation of or with the approval of, at least two-thirds of the directors who then qualified as Incumbent Directors (so long as such director was not nominated by a person who commenced or threatened to commence an election contest or proxy solicitation by or on behalf of a Person (other than the Board) or who has

entered into an agreement to effect a Change in Control or expressed an intention to cause such a Change in Control); or

(d) A majority of the members of the Board of Directors in office immediately prior to a proposed transaction determine by a written resolution that such proposed transaction, if taken, will be deemed a Change in Control and such proposed transaction is consummated.

Article XII

Miscellaneous

12.1 Effect on Other Plans. Except as otherwise required by law, no action taken under the Plan shall be taken into account in determining any benefits under any pension, retirement, thrift, profit sharing, group insurance or other benefit plan maintained by the Company or any Subsidiaries, unless such other plan specifically provides for such inclusion.

12.2 Transfer Restrictions. Except as provided in Article XII, Section 12.3, no Award shall be transferable other than by will or the laws of descent and distribution. Any Option or SAR shall be exercisable (i) during the lifetime of the grantee, only by the grantee or, to the extent permitted by the Code, by an appointed guardian or legal representative of the grantee, and (ii) after death of the grantee, only by the grantee's legal representative or by the person who acquired the right to exercise such Option or SAR by bequest or inheritance or by reason of the death of the grantee.

12.3 Transfer of Options. The Committee may, in its discretion, authorize all or a portion of the Options to be granted to an Optionee to be on terms which permit transfer by such Optionee to an immediate family member of the Optionee who acquires the options from the Optionee through a gift or a domestic relations order. For purposes of this Article XII, Section 12.3, "family member" includes any child, stepchild, grandchild, parent, stepparent, grandparent, spouse, sibling, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law or sister-in-law, including adoptive relationships, trusts for the exclusive benefit of these persons and any other entity owned solely by these persons, provided that the Stock Option Agreement pursuant to which such Options are granted must be approved by the Committee and must expressly provide for transferability in a manner consistent with this Section and provided further that subsequent transfers of transferred options shall be prohibited except those in accordance with Article XII, Section 12.2. Following transfer, any such Options shall continue to be subject to the same terms and conditions as were applicable immediately prior to transfer. The events of termination of service of Article VI, Section 6.4 hereof shall continue to be applied with respect to the original Optionee, following which the options shall be exercisable by the Transferee only to the extent and for the periods specified in Article VI, Section 6.4.

12.4 Withholding Taxes. The Company shall have the right to withhold from any settlement hereunder any federal, state, or local taxes required by law to be withheld, or require payment in the amount of such withholding. If settlement hereunder is in the form of Stock, such withholding may be satisfied by the withholding of shares of Stock by the Company, unless the grantee shall pay to the Company an amount sufficient to cover the amount of taxes required to be withheld, and such withholding of shares does not violate any applicable laws, rules or regulations of federal, state or local authorities.
