PROXY STATEMENT

For Annual Meeting of Stockholders

To Be Held on April 26, 2005

INTRODUCTION

      The accompanying proxy, mailed together with this proxy statement, is solicited by and on behalf of the Board of Directors of Noble Energy, Inc., a Delaware corporation (the “Company”), for use at the annual meeting of stockholders of the Company to be held at 9:30 a.m. Central Time on Tuesday, April 26, 2005, at the Wyndham Greenspoint Hotel, 12400 Greenspoint Drive, Houston, Texas 77060, and at any adjournment or postponement thereof. The approximate date on which this proxy statement and the accompanying proxy will first be mailed to stockholders of the Company is March 24, 2005.

      Shares represented by valid proxies will be voted at the meeting in accordance with the directions given. If no directions are given, the shares will be voted in accordance with the recommendations of the Board of Directors unless otherwise indicated. Any stockholder of the Company returning a proxy has the right to revoke the proxy at any time before it is voted by communicating the revocation in writing to Arnold J. Johnson, Secretary, Noble Energy, Inc., 100 Glenborough Drive, Suite 100, Houston, Texas 77067, or by executing and delivering a proxy bearing a later date. No revocation by written notice or by delivery of another proxy shall be effective until the notice of revocation or other proxy, as the case may be, has been received by the Company at or prior to the meeting.

      In order for an item of business proposed by a stockholder to be considered properly brought before the annual meeting of stockholders as an agenda item or to be included in the Company’s proxy statement, the By-laws of the Company require that the stockholder give written notice to the Secretary of the Company. The notice must specify certain information concerning the stockholder and the item of business proposed to be brought before the meeting. The notice must be received by the Secretary of the Company no later than 120 calendar days before the first anniversary of the release date of the previous year’s annual meeting proxy statement; provided, however, that in the event that (i) no annual meeting was held in the previous year or (ii) the date of the annual meeting has changed by more than 30 days from the date of the previous year’s meeting, notice by the stockholder must be received no later than the close of business on the tenth day following the earlier of the day on which notice of the meeting date was mailed or public disclosure of the meeting date was made for such notice to be timely. Accordingly, proper notice of a stockholder proposal for the 2006 annual meeting must be received by the Company no later than November 24, 2005.

Voting Procedures and Tabulation

      Holders of record of common stock of the Company may vote using one of the following three methods:

      Proxies submitted by telephone or the Internet are treated in the same manner as if the stockholder had signed, dated and returned the proxy card by mail. Therefore, stockholders of record electing to vote by telephone or the Internet should not return their proxy cards by mail.

      Stockholders whose shares of common stock of the Company are held in the name of a bank, broker or other holder of record (that is, “street name”) will receive separate instructions from such holder of record regarding the voting of proxies.

      The Company will appoint one or more inspectors of election to act at the meeting and to make a written report thereof. Prior to the meeting, the inspectors will sign an oath to perform their duties in an impartial manner and according to the best of their ability. The inspectors will ascertain the number of shares outstanding and the voting power of each, determine the shares represented at the meeting and the validity of proxies and ballots, count all votes and ballots, and perform certain other duties as required by law.

      The inspectors will tabulate the number of votes cast for, or withheld from, each matter submitted at the meeting for a stockholder vote. Votes that are withheld will be excluded entirely from the vote and will have no effect. Under the rules of the New York Stock Exchange (“NYSE”), brokers who hold shares in street name have the discretionary authority to vote on certain “routine” items when they have not received instructions from beneficial owners. For purposes of the 2005 annual meeting, routine items include the election of directors and the ratification of the appointment of the independent auditor. In instances where brokers are prohibited from exercising discretionary authority and no instructions are received from beneficial owners with respect to such item (so-called “broker non-votes”), the shares they hold will not be considered part of the voting power present and, therefore, will have no effect on the vote. For purposes of the 2005 annual meeting, brokers will be prohibited from exercising discretionary authority with respect to the proposal to approve a new 2005 Stock Plan for Non-Employee Directors of the Company.

CORPORATE GOVERNANCE

      The Company is committed to integrity, reliability and transparency in its disclosures to the public. To this end, the Company adheres to corporate governance practices designed to ensure that its business is conducted in the best interests of its stockholders and in full compliance with its legal and regulatory obligations, including the corporate governance listing standards of the NYSE and the rules and regulations of the Securities and Exchange Commission (“SEC”). In particular, the Company has:

      You can access all committee charters, the Company’s Corporate Governance Guidelines, Code of Business Conduct and Ethics, Code of Ethics for Chief Executive and Senior Financial Officers and other corporate governance materials in the “Corporate Governance” section of the Company’s website at www.nobleenergyinc.com, or you may receive copies without charge by writing to the Company at: Noble Energy, Inc., 100 Glenborough Drive, Suite 100, Houston, Texas 77067, Attention: Investor Relations.

VOTING SECURITIES

      Only holders of record of common stock of the Company, par value $3.33¹/3 per share, at the close of business on March 15, 2005, the record date for the annual meeting, are entitled to notice of, and to vote at, the meeting. A majority of the shares of common stock entitled to vote, present in person or represented by proxy, is necessary to constitute a quorum. Abstentions and broker non-votes on filed proxies and ballots are counted as present for establishing a quorum. On the record date for the annual meeting, there were issued and outstanding 59,308,957 shares of common stock. Each share of common stock is entitled to one vote.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS

      The following tabulation sets forth as of March 1, 2005 information with respect to the only persons who were known to the Company to be beneficial owners of more than five percent of the outstanding shares of common stock of the Company.

PROPOSAL I

ELECTION OF DIRECTORS

      The Company, its wholly-owned subsidiary, Noble Energy Production, Inc., and Patina Oil & Gas Corporation (“Patina”) entered into an agreement and plan of merger on December 15, 2004 (the “Merger Agreement”). Under the Merger Agreement, the Company will acquire Patina through a merger of Patina into Noble Energy Production, Inc. (the “Merger”). Following the Merger, Noble Energy Production, Inc. will be the surviving entity and will continue as a wholly-owned subsidiary of the Company.

      For more information regarding the Merger, you are urged to read the joint proxy statement/prospectus on Form S-4, which the Company and Patina filed with the SEC on January 25, 2005 and subsequently amended and filed with the SEC on March 15, 2005. These materials are not yet final and may be further amended. You are urged to read this joint proxy statement/prospectus, as amended, and any other relevant materials filed by the Company or Patina because they contain, or will contain, important information about the Company, Patina and the Merger. The preliminary materials filed on January 25, 2005, the subsequent amendment filed on March 15, 2005, the definitive versions of these materials and other relevant materials (when they become available) and any other documents filed by the Company or Patina with the SEC, may be obtained free of charge from the SEC’s website at www.sec.gov. In addition, the documents filed with the SEC by the Company may be obtained free of charge from the Company’s website at www.nobleenergyinc.com.

      Completion of the Merger is subject to customary closing conditions, including the approval of the stockholders of the Company and Patina. Although the Company expects the Merger to be completed in April of 2005, the actual closing date is not known at this time. Consequently, the Merger may not be completed prior to the Company’s annual meeting on April 26, 2005.

      As of the date of this proxy statement, the Company’s Board of Directors consists of five directors, four of whom are non-employee directors. Under the Merger Agreement, the Company’s Board of Directors, after consultation with the Governance Committee, has agreed to appoint two current Patina directors to the Company’s Board of Directors upon completion of the Merger. Therefore, if the Merger is completed prior to the annual meeting, a total of seven nominees will be voted upon at the annual meeting for election to the Board of Directors: five of the nominees will have served as directors since the last annual meeting and the remaining two will have been appointed to the Board of Directors in connection with the Merger. If the Merger is not completed prior to the annual meeting, only the five incumbent directors will be voted upon for election to the Board of Directors. Accordingly, this proposal consists of two alternate slates of nominees for election as directors. One slate, consisting of seven nominees, will be voted on at the annual meeting if the Merger is completed prior to the annual meeting. The other slate, consisting of five nominees, will be voted on at the annual meeting if the Merger is not completed prior to the annual meeting. The Company requests your vote with respect to each of the two slates.

      Information regarding the business experience of each nominee is provided below. All directors are elected annually to serve until the next annual meeting and until successors are elected.

      Directors are elected by plurality vote of the shares present at the annual meeting, meaning that the director nominee with the most affirmative votes for a particular slot is elected for that slot. If the Merger is completed prior to the annual meeting, the proxyholders will vote in favor of the seven persons listed below under the section “Company Nominees for Director Following Completion of the Merger,” unless contrary instructions are given. If the Merger is not completed prior to the annual meeting, the proxyholders will vote in favor of the five persons listed below under the section “Company Nominees for Director Prior to Completion of the Merger,” unless contrary instructions are given.

      If you sign your proxy card but do not give instructions with respect to the voting of directors and if the Merger is completed prior to the annual meeting, your shares will be voted for the seven persons recommended by the Board of Directors. If you sign your proxy card but do not give instructions with respect

to the voting of directors and if the Merger is not completed prior to the annual meeting, your shares will be voted for the five persons recommended by the Board of Directors in that case. If you wish to give specific instructions with respect to the voting of directors, you must do so with respect to both the slate of seven persons who will be voted upon at the annual meeting if the Merger is completed prior to the annual meeting and the slate of five persons who will be voted upon at the annual meeting if the Merger is not completed prior to the annual meeting.

      The Board of Directors expects that all of the nominees will be available to serve as directors as indicated. In the event that any nominee should become unavailable, however, the proxyholders will vote for a nominee or nominees who would be designated by the Board of Directors unless the Board of Directors chooses to reduce the number of directors serving on the Board of Directors.

      Michael A. Cawley — See biography above.

      Edward F. Cox — See biography above.

      Charles D. Davidson — See biography above.

      Kirby L. Hedrick — See biography above.

      Bruce A. Smith — See biography above.

      Generally, the Company’s By-laws provide that a stockholder must deliver written notice to the Secretary of the Company no later than 90 calendar days prior to the annual meeting naming the stockholder’s nominee(s) for director and specifying certain information concerning the stockholder and nominee(s). Accordingly, a stockholder’s nominee(s) for director to be presented at the 2006 annual meeting of stockholders must be received by the Company no later than January 25, 2006.

INFORMATION CONCERNING THE BOARD OF DIRECTORS

      The Board of Directors held thirteen meetings in 2004, consisting of five regular meetings, the annual organizational meeting and seven special meetings.

      All directors are expected to attend each annual meeting of stockholders. A director who is unable to attend the annual meeting, which it is understood will occur on occasion, is expected to notify the Chairman of the Board in advance of such meeting. Attendance at the annual meeting will be considered by the Governance Committee in assessing each director’s performance. Last year, all directors attended the annual meeting of stockholders.

Independence of the Board of Directors

      The Company is listed on the NYSE and therefore must comply with certain standards of corporate governance established for all NYSE-listed companies, including the requirement that a majority of the Board of Directors be independent and every member of each of the Audit Committee, the Governance Committee and the Compensation Committee be independent. A director is considered independent only if the Board of Directors affirmatively determines that the director has no material relationship with the Company. The standards relied upon by the Board of Directors in affirmatively determining a director’s independence are set forth in the NYSE Listed Company Manual and generally provide that: (i) a director who is an employee, or whose immediate family member (defined as a spouse, parent, child, sibling, father- and mother-in-law, son- and daughter-in-law and anyone, other than a domestic employee, sharing the director’s home) is an executive officer, of the Company, would not be independent for a period of three years after termination of such relationship; (ii) a director who receives, or whose immediate family receives as an executive officer of the Company, more than $100,000 per year in direct compensation from the Company, except for certain permitted payments, would not be independent for a period of three years after ceasing to receive such amount; (iii) a director who is affiliated with or employed by, or whose immediate family member is affiliated with or employed in a professional capacity by, a present or former internal or external auditor of the Company

would not be independent for a period of three years after the termination of such relationship; (iv) a director who is employed, or whose immediate family member is employed, as an executive officer of another company where any of the Company’s present executives serve on the other company’s compensation committee would not be independent for a period of three years after the termination of such relationship; and (v) a director who is an executive officer or employee, or whose immediate family member is an executive officer, of a company that makes payments to, or receives payments from, the Company for property or services in an amount which, in any single fiscal year, exceeds the greater of $1 million, or 2% of such other company’s consolidated gross revenues, would not be independent until a period of three years after falling below such threshold. In addition to these objective standards, and in compliance with the NYSE rules, the Board of Directors has adopted a general standard that no director who has any other material relationship with the Company that could interfere with the director’s ability to exercise independent judgment will be considered independent. The Board of Directors exercises appropriate discretion in identifying and evaluating the materiality of any relationships directors may have with the Company.

      The Board of Directors, applying the standards referenced above, affirmatively determined that Michael A. Cawley, Edward F. Cox, Kirby L. Hedrick, and Bruce A. Smith are independent for board membership purposes. The Board of Directors also determined that all members of the Audit Committee, Governance Committee and Compensation Committee are independent. The Board of Directors has not yet made an independence determination with respect to Jeffrey L. Berenson and Thomas J. Edelman, the two Patina directors to be appointed to the Board of Directors upon completion of the Merger pursuant to the Merger Agreement.

Communications with Directors

      Stockholders and other interested parties may contact any member of the Board of Directors, any Board of Directors committee or any chair of any such committee by mail, electronically or by calling the Company’s independent, toll-free compliance line. To communicate by mail with the Board of Directors, any individual director or any group or committee of directors, correspondence should be addressed to the Board of Directors or any individual director or group or committee of directors by either name or title. All correspondence should be sent to Noble Energy, Inc., Attention: Secretary, at 100 Glenborough, Suite 100, Houston, Texas 77067. To communicate with any of the Company’s directors electronically, stockholders should go to the Company’s website at www.nobleenergyinc.com. Under the headings “Corporate Governance/ Corporate Governance Guidelines,” you will find a link under Exhibit 3 (“Shareholder Communications with Directors”) that may be used for writing an electronic message to the Board of Directors, any individual director, or any group or committee of directors. In addition, stockholders may call the Company’s independent, toll-free compliance line listed on the Company’s website under the headings “Corporate Governance/ Audit Committee Complaints Policy.”

      All stockholder communications properly received will be reviewed by the office of the Company’s General Counsel to determine whether the contents represent a message to the Company’s directors. Any contents that are not in the nature of advertising, promotions of a product or service, or patently offensive material will be forwarded promptly to the appropriate director or directors.

Evaluation of Director Nominees

      The Governance Committee believes that the minimum qualifications for serving as a director of the Company are that a nominee demonstrate, by significant accomplishment in his or her field, an ability to make a meaningful contribution to the Board of Directors’ oversight of the business and affairs of the Company and have an impeccable record and reputation for honest and ethical conduct in both his or her professional and personal activities. Nominees for director shall be those people who, after taking into account their skills, expertise, integrity, diversity, character, judgment, age, independence, corporate experience, length of service, potential conflicts of interest and commitments (including, among other things, service on the boards or comparable governing bodies of other public companies, private business companies, charities, civic bodies or similar organizations) and other qualities, are believed to enhance the Board’s ability to manage and direct, in an effective manner, the affairs and business of the Company, including, when applicable, to enhance the

ability of committees of the Board of Directors to fulfill their duties and/or to satisfy any independence requirements imposed by law, regulation or listing requirements of the NYSE.

      In general, nominees for director should have an understanding of the workings of large business organizations such as the Company and senior level executive experience, as well as the ability to make independent, analytical judgments, the ability to be an effective communicator and the ability and willingness to devote the time and effort to be an effective and contributing member of the Board of Directors. In addition, the Governance Committee will examine a candidate’s specific experiences and skills, time availability in light of other commitments, potential conflicts of interest and independence from management and the Company. The Governance Committee will also seek to have the Board of Directors represent a diversity of backgrounds, experience, gender and race.

      The Governance Committee will identify potential nominees by asking current directors and executive officers to notify the Governance Committee if they become aware of persons, meeting the criteria described above, who have had a change in circumstances that might make them available to serve on the Board of Directors – for example, retirement as a CEO or CFO of a public company or exiting government or military service or business and civic leaders in the communities in which the Company’s facilities are located. The Governance Committee also, from time to time, will engage firms that specialize in identifying director candidates. The Governance Committee will also consider candidates recommended by stockholders.

      Once a person has been identified by the Governance Committee as a potential candidate, the Governance Committee may collect and review available information regarding the person to assess whether the person should be considered further. If the Governance Committee determines that the candidate warrants further consideration, the Governance Committee Chair or another member of the Governance Committee will contact the person. Generally, if the person expresses a willingness to be considered and to serve on the Board of Directors, the Governance Committee will request information from the candidate, review the person’s accomplishments and qualifications, including in light of any other candidates that the Governance Committee might be considering, and conduct one or more interviews with the candidate. In certain instances, Governance Committee members may contact one or more references provided by the candidate or may contact other members of the business community or other persons that may have greater first-hand knowledge of the candidate’s accomplishments. The Governance Committee’s evaluation process will be the same whether or not a candidate is recommended by a stockholder, although the Board of Directors may take into consideration the number of shares held by the recommending stockholder and the length of time that such shares have been held.

      The Governance Committee will consider director nominees of stockholders, provided that such recommendations are made in writing to the attention of the Secretary and received by the Secretary not less than 90 days in advance of an annual stockholder meeting. A stockholder must include the following information with each recommendation for a director nominee:

Committees of the Board of Directors

      The Board of Directors has four standing committees, whose names, current members and purposes are as follows:

      Each director attended at least 75% of the meetings of the Board of Directors and its committees of which such director was a member during the past fiscal year.

Compensation Committee Interlocks and Insider Participation

      Kirby L. Hedrick, Edward F. Cox and Bruce A. Smith served on the Compensation Committee during 2004. There were no Compensation Committee interlocks nor insider (employee) participation during 2004.

Compensation of Directors

      Directors who are not officers of the Company or any of its subsidiaries receive an annual retainer of $37,500 and a fee of $1,000 for each Board of Directors or committee meeting attended. With the exception of

the Audit Committee, the chair of each committee, if not also an employee or officer of the Company, receives an additional annual fee of $5,000. The chair of the Governance Committee, Mr. Cawley, has elected to waive the chair’s fee. The chair of the Audit Committee receives an additional $15,000 annual fee. The position of “Lead Independent Director,” which is filled by a non-employee director, receives an additional annual fee of $20,000. The Company also reimburses directors for travel, lodging and related expenses they incur in attending Board of Directors and committee meetings.

      Non-employee directors are entitled to the benefit of the Company’s Non-Employee Director Fee Deferral Plan. Under the terms of this plan, non-employee directors may, during a specified period of time each year, elect to have all or any portion of their director fees deferred for future payment by the Company.

      Non-Employee Director Stock Option Plan. The 1988 Nonqualified Stock Option Plan for Non-Employee Directors, as amended, provides for the grant of nonqualified stock options to each director of the Company who is neither an employee nor officer of the Company. The plan provides generally for a fixed grant of options annually on each February 1 during the term of the plan. An automatic grant is made (i) to each new non-employee director at the time of the director’s election of an initial option to purchase 10,000 shares of common stock and (ii) to each incumbent non-employee director on February 1 each year of an option to purchase 5,000 shares of common stock. The purchase price per share of common stock under the option is fair market value on the date of grant. The options have a ten-year term and are initially exercisable one year after date of grant.

      The Company’s Board of Directors has adopted a new 2005 Stock Plan for Non-Employee Directors of Noble Energy, Inc., subject to the approval of the Company’s stockholders at the annual meeting. If the 2005 plan is approved by the Company’s stockholders, the 1988 plan will terminate immediately. For a description of the 2005 plan, see “Proposal III – Approval of New 2005 Stock Plan For Non-Employee Directors.”

PROPOSAL II

RATIFICATION OF APPOINTMENT OF INDEPENDENT AUDITOR

      The Audit Committee of the Board of Directors has appointed the firm of KPMG LLP to serve as independent auditor of the Company for the fiscal year ending December 31, 2005. This firm has audited the accounts of the Company since May 2002. Although action by the stockholders on this matter is not required, the Audit Committee believes that it is important to seek stockholder ratification of this appointment in light of the critical role played by the independent auditor in maintaining the integrity of Company financial controls and reporting.

      One or more members of KPMG LLP are expected to be present at the annual meeting, will be able to make a statement if they so desire, and will be available to respond to appropriate questions.

      The Board of Directors recommends that stockholders vote FOR ratification of the appointment of KPMG LLP as independent auditor.

PROPOSAL III

APPROVAL OF NEW 2005 STOCK PLAN FOR NON-EMPLOYEE DIRECTORS

      The Board of Directors has adopted the 2005 Stock Plan for Non-Employee Directors of Noble Energy, Inc. (the “2005 Plan”), subject to the approval of the 2005 Plan by the stockholders of the Company at the annual meeting. The purposes of the 2005 Plan are to provide each non-employee director of the Company with an added incentive to continue in the service of the Company and a more direct interest in the future success of the operations of the Company by granting to such directors options to purchase shares of the Company’s common stock and awards of restricted shares of common stock.

      The following is a summary of the principal features of the 2005 Plan. This summary does not purport to be a complete description of all of the provisions of the 2005 Plan and is qualified in its entirety by the text of

the 2005 Plan, a copy of which is attached to this proxy statement as Appendix A. Capitalized terms not otherwise defined below have the meanings ascribed to them in the 2005 Plan.

General

      The 2005 Plan authorizes the issuance of up to 400,000 shares of common stock. Any shares of common stock allocable to the unexercised portion of an option that expires or terminates will again be available for the purposes of the 2005 Plan. The 2005 Plan contains provisions for the adjustment of the number of shares of common stock to be granted or available for grant under options and restricted stock awards, and for the adjustment of the shares subject to unexercised options, in the event of common stock splits or combinations, dividends payable in common stock or the occurrence of certain other events.

      The 2005 Plan is administered by the Board of Directors and, subject to certain minimum and maximum annual grant limitations, is designed to allow the Board to adjust the value and the form of the grants to be made under the 2005 Plan from time to time in order to permit the Company to respond to market conditions and remain competitive in its non-employee director compensation practices. Under the 2005 Plan, certain options and restricted stock awards are granted automatically to incumbent and new non-employee directors. In addition, the Board of Directors has the discretion to grant additional options and restricted stock awards to the non-employee directors and to determine the restrictions, terms and conditions applicable to such grants.

Stock Options

      Each new non-employee director will be granted an option to purchase 5,600 shares of common stock on the date of such non-employee director’s election to the Board of Directors as a director. On each February 1 during the term of the 2005 Plan, each incumbent non-employee director serving the Company on such date automatically will be granted an option to purchase 1,400 shares of common stock. In addition to the foregoing automatic grants of options, at any time the Board of Directors in its discretion may grant an additional option to any non-employee director who previously has received or concurrently is receiving a February 1 automatic option grant; provided, however, that the aggregate number of shares of common stock that may be subject to options granted by the Board of Directors in its discretion to a particular non-employee director during any calendar year, when added to the number of shares of common stock that are subject to the option automatically granted to such non-employee director on February 1 of that year, cannot exceed 5,600.

      The price at which each share of common stock covered by an option may be purchased is the fair market value of such share on the date of the grant of such option. Each option will be exercisable from time to time over the period of time commencing one (1) year from the date of the grant of such option and ending (i) in the case of an option automatically granted under the 2005 Plan, upon the expiration of ten (10) years from the date of such grant, or (ii) in the case of an option granted by the Board of Directors in its discretion, upon the expiration date specified for such option by the Board of Directors at the time of the grant of such option. Each option granted to a non-employee director under the 2005 Plan will, however, become exercisable in full (i) upon the death of such non-employee director, (ii) upon the mandatory retirement of such non-employee director as a regular director because of age in accordance with Article III of the By-laws of the Company, or (iii) in the event of a Change in Control as defined in the 2005 Plan.

      If a non-employee director’s service as a director terminates within the exercise period applicable to an option granted to such non-employee director, the non-employee director (or if such termination of service is by reason of death, the executor or administrator of the non-employee director’s estate or person who has acquired the option by bequest, inheritance or permitted transfer) may exercise such option, to the extent such option was exercisable at the time of such termination of service, for a period ending on the earlier of (i) the expiration of five (5) years from such termination of service, or (ii) the expiration of the exercise period applicable to such option.

      The options granted under the 2005 Plan are transferable only by will or the laws of descent and distribution or to a permitted transferee (as defined below). An option may be transferred to a permitted transferee if (i) there is no consideration for the transfer, (ii) the original optionee remains liable for all

withholding obligations associated with the exercise of the option, (iii) the original optionee notifies the Company of the transfer and provides certain information with respect to the permitted transferee, and (iv) the Board of Directors approves the form of the transfer documents effectuating the transfer. The term “permitted transferee” means, with respect to an original optionee, (i) any child, stepchild, grandchild, parent, stepparent, grandparent, spouse, former spouse, sibling, niece, nephew, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law or sister-in-law of the original optionee, including adoptive relationships, (ii) any person sharing the original optionee’s household (other than a tenant or an employee), (iii) a trust in which the persons described in clauses (i) and (ii) above have more than fifty percent of the beneficial interest, (iv) a foundation in which the original optionee and/or persons described in clauses (i) and (ii) above control the management of assets, and (v) any other entity in which the original optionee and/or persons described in clauses (i) and (ii) above own more than fifty percent of the voting interests.

Restricted Stock Awards

      Each new non-employee director will be granted 2,400 restricted shares of common stock on the date of such non-employee director’s election to the Board of Directors as a director. On each February 1 during the term of the 2005 Plan, each incumbent non-employee director serving the Company on such date automatically will be granted 600 restricted shares of common stock. In addition to the foregoing automatic grants of restricted shares of common stock, at any time the Board of Directors in its discretion may grant additional restricted shares of common stock to any non-employee director who previously has received or concurrently is receiving a February 1 automatic grant of restricted shares of common stock; provided, however, that the aggregate number of restricted shares of common stock that may be granted by the Board of Directors in its discretion to a particular non-employee director during any calendar year, when added to the number of shares of common stock that are subject to the grant of restricted shares of common stock automatically granted to such non-employee director on February 1 of that year, cannot exceed 2,400. Each grant of restricted shares of common stock under the 2005 Plan will be restricted for a period of at least one year from the date of such grant, and may not be sold, assigned, transferred, discounted, exchanged, pledged or otherwise encumbered or disposed of until all of the restrictions, terms and conditions applicable to such restricted shares have been satisfied. During the restricted period, the non-employee director to whom the restricted shares of common stock have been granted will be the record owner of such shares and will have all of the rights of a stockholder with respect to such shares, including the right to vote and the right to receive dividends or other distributions made with or paid with respect to such shares.

      Subject to the express provisions of the 2005 Plan, the Board of Directors in its discretion will determine the restrictions, terms and conditions that will apply to each grant of restricted shares of common stock granted pursuant to the 2005 Plan; provided, however, that the restrictions applicable to each such grant will terminate in the event of a Change in Control or if such non-employee director (i) dies or becomes disabled while a director of the Company, or (ii) retires as a regular director of the Company because of age in accordance with the mandatory retirement provisions of Article III of the By-laws of the Company.

Amendment of the Plan

      The Board of Directors may at any time and from time to time amend, modify or suspend the 2005 Plan, provided that no such amendment, modification or suspension shall (1) adversely affect an option or restricted stock award theretofore granted to a non-employee director, or deprive a non-employee director of any shares of common stock such non-employee director has acquired or may acquire under such an option or restricted stock award, without his or her consent, or (2) be made without the approval of the stockholders of the Company if such amendment, modification or suspension would (i) expand the types of grants that may be made under the 2005 Plan, (ii) increase the total number of shares of common stock that may be granted under the 2005 Plan or decrease the exercise price of Options granted or to be granted under the 2005 Plan (other than in accordance with the 2005 Plan’s antidilution provisions), (iii) materially expand the class of persons eligible to be granted options or restricted stock awards under the 2005 Plan, (iv) materially increase the benefits accruing to non-employee directors under the 2005 Plan, (v) extend the term of the 2005 Plan or the exercise period applicable to an option granted thereunder, or (vi) constitute a material revision of the

2005 Plan requiring stockholder approval pursuant to Section 303A.08 of the NYSE Listed Company Manual or applicable law.

Termination

      Unless previously terminated by the Board of Directors in its discretion, the 2005 Plan will terminate at the close of business on March 31, 2015, after which time no further grants may be made under the 2005 Plan.

United States Federal Income Tax Consequences

      The following summary is based upon an analysis of the Internal Revenue Code (the “Code”) as currently in effect, and existing laws, judicial decisions, administrative rulings, regulations and proposed regulations, all of which are subject to change. Moreover, the following is only a summary of United States federal income tax consequences and such consequences may be either more or less favorable than those described below depending on a taxpayer’s particular circumstances.

      All options granted under the 2005 Plan are nonqualified options that are not entitled to special tax treatment under Section 422 of the Code. The 2005 Plan is also not qualified under Section 401(a) of the Code and is not subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended.

      For federal income tax purposes, no income will be recognized by a non-employee director to whom an option is granted (an “optionee”) upon the grant of an option. Upon exercise of an option, the optionee will recognize ordinary income in an amount equal to the excess of the fair market value of the shares on the date of exercise over the option price of such shares. The Company will be entitled to a deduction equal to the amount of ordinary income recognized by the optionee at the time of such recognition by the optionee. The basis of the shares transferred to an optionee pursuant to exercise of an option is the price paid for such shares plus an amount equal to any income recognized by the optionee as a result of the exercise of such option. If the optionee thereafter sells shares acquired upon exercise of an option, any amount realized over the basis of such shares will constitute capital gain to such optionee for federal income tax purposes.

      If the restrictions on the shares of common stock granted to a non-employee director (an “awardee”) are of a nature that the shares are both subject to a substantial risk of forfeiture and not freely transferable (within the meaning of Section 83 of the Code), the awardee will not recognize income for federal income tax purposes at the time of the award unless the awardee elects, no later than thirty (30) days after the receipt of such shares, to include the fair market value of such shares on the date of the grant, less any amount paid for such shares, in gross income for the year of the grant pursuant to Section 83(b) of the Code. In the absence of such an election, the awardee will be required to include in income for federal income tax purposes on the date the shares either become freely transferable or are no longer subject to a substantial risk of forfeiture (within the meaning of Section 83 of the Code), the fair market value of the shares on such date, less any amount paid for the shares. The Company will be entitled to a deduction at the time of income recognition to the awardee in an amount equal to the amount the awardee is required to include in income with respect to the shares. If a Code Section 83(b) election is made, no additional income will be recognized by the awardee upon the lapse of restrictions on the restricted shares of common stock, but if the shares are subsequently forfeited, the awardee may not deduct the income that was recognized pursuant to the Code Section 83(b) election at the time of the receipt of the shares.

      Dividends on restricted shares of common stock that are paid to an awardee before the expiration of the restriction period will be additional compensation taxable as ordinary income to the awardee unless the awardee made an election under Code Section 83(b) with respect to such shares. The Company will be entitled to a corresponding tax deduction equal to the dividends includible in the awardee’s income as compensation. If the awardee has made a Code Section 83(b) election with respect to such shares, the dividends thereon will be treated as dividend income, rather than additional compensation, to the awardee.

      If the restrictions on the shares of common stock granted to an awardee are not of a nature that the shares are both subject to a substantial risk of forfeiture and not freely transferable (within the meaning of Section 83

of the Code), the awardee will recognize ordinary income for federal income tax purposes at the time of the transfer of the shares in an amount equal to the fair market value of the shares on the date of the transfer, less any amount paid therefor. The Company will be entitled to a deduction at that time in an amount equal to the amount the awardee is required to include in income with respect to the shares.

Vote Required and Board of Directors Recommendation

      At the annual meeting, stockholders are being asked to approve the 2005 Plan. Such approval will require the affirmative vote of a majority of the votes cast on the proposal, provided that the total number of votes cast on the proposal represents over 50% of the common stock entitled to vote on the proposal.

      The Board of Directors recommends that you vote FOR the approval of the 2005 Plan.

SECURITY OWNERSHIP OF DIRECTORS AND EXECUTIVE OFFICERS

      The following tabulation sets forth, as of March 1, 2005, the shares of common stock beneficially owned by each director, each named executive officer listed in the Summary Compensation Table included elsewhere in this proxy statement, and all directors and named executive officers as a group.

EXECUTIVE COMPENSATION

      The following report of the Compensation, Benefits and Stock Option Committee of the Board of Directors and the information under the section “Performance Graph” shall not be deemed to be “soliciting material” or to be “filed” with the SEC or subject to the SEC’s proxy rules, except for the required disclosure in this proxy statement, or subject to the liabilities of Section 18 of the Securities Exchange Act of 1934 (the “Exchange Act”), and the information shall not be deemed to be incorporated by reference into any filing made by the Company under the Securities Act of 1933 or the Exchange Act.

REPORT OF THE COMPENSATION, BENEFITS

AND STOCK OPTION COMMITTEE

ON EXECUTIVE COMPENSATION

To the Stockholders of

Noble Energy, Inc.:

      The purpose of the Compensation, Benefits and Stock Option Committee (the “Compensation Committee”) is to: (a) review and approve corporate goals and objectives in the areas of: (1) salary and bonus compensation, (2) benefits, and (3) equity-based compensation, as these areas relate to the Chief Executive Officer (CEO), evaluating the CEO’s performance based on those goals and objectives and, either as a committee or together with the other independent directors (as directed by the Board of Directors), determine and approve the CEO’s compensation level based on that evaluation; (b) make recommendations to the Board with respect to non-CEO compensation, incentive compensation plans and equity-based plans; and (c) produce a committee report on executive compensation as required by the SEC to be included in the Company’s annual proxy statement or annual report on Form 10-K.

Compensation Philosophy

      The Company’s compensation philosophy is to pay employees for the value of their contributions, recognizing differences in individual performance through the various components of total compensation. Total compensation consists of base salary, incentives and benefits. The Company’s objective is to provide a total compensation program that is flexible enough to respond to changing market conditions and that also aligns compensation levels with sustained performance and comparable industry benchmarks. Compensation levels are evaluated annually to ensure they are market competitive and that they reflect relative performance within the Company.

      The executive compensation policy of the Company, which is endorsed by the Compensation Committee, is to provide a compensation program that will attract, motivate and retain persons of high quality and will support a long-standing internal culture of loyalty and dedication to the interests of the Company. In administering the executive compensation program, the Compensation Committee is mindful of the following principles and guidelines, which are supported by the Board of Directors.

      Base salaries for executive officers should be competitive with comparable positions in peer companies. A sufficient portion of annual compensation should be at risk in order to align the interests of executives with those of stockholders of the Company. This variable part of annual compensation should reflect both corporate and individual performance. As a person’s level of responsibility increases, a greater portion of total compensation should be at risk and the mix of total compensation should be weighted more heavily in favor of incentive-based compensation. Stock options, restricted stock and performance units together provide a balanced long-term incentive program that aligns the interests of our stockholders and our executives toward the enhancement of stockholder value.

Components of Compensation Program

      The 2004 executive compensation program consisted of three principal elements, which are discussed below: base salary, a short-term incentive plan and a long-term incentive plan.

2004 Compensation of CEO

      Davidson Total Salary, STIP Bonus and LTIP Awards. After assessing the Company’s overall performance last year on the basis of the criteria described above, for 2004 the Compensation Committee authorized for Mr. Davidson (1) a total salary of $741,667, (2) a bonus under the Company’s STIP of $1,320,000, which was paid in February 2005 based on the Company’s 2004 performance, and (3) awards under the Company’s LTIP of 43,290 stock options, 11,160 shares of restricted stock and 1,033,200 performance units.

Change of Control Agreements

      Davidson Change of Control Agreement. The Company’s change of control agreement with Mr. Davidson includes provisions regarding the severance package that Mr. Davidson may be entitled to if he is terminated within 24 months after a change of control of the Company. A change of control for purposes of Mr. Davidson’s agreement will be deemed to have occurred if any of the following conditions occur:

      If the Company terminates Mr. Davidson for cause, incapacity due to physical or mental illness, or death, the Company has no further obligation to Mr. Davidson. A termination for cause, upon the occurrence of certain actions or circumstances enumerated in the change of control agreement, may only be made by the affirmative vote of a majority of the members of the Board of Directors.

      If the Company terminates Mr. Davidson for any other reason within 24 months after a change of control of the Company, then the Company shall pay or provide the following to Mr. Davidson:

      The above amounts will have a gross-up payment applied to them to offset fully the effect of any federal excise tax.

      Change of Control Agreements for Other Officers. As of the date of this proxy statement, each executive officer of the Company has a change of control agreement similar to Mr. Davidson’s as described above. These change of control agreements generally incorporate the same terms and conditions as Mr. Davidson’s agreement, except a different multiplier is used in the executive officers’ agreements. This multiplier affects two provisions of the agreement: (i) the lump sum payment that will be made upon termination and (ii) the provision of insurance benefits. For example, the multiplier in Mr. Davidson’s agreement is 2.99, so he will receive a lump sum of 2.99 times his annual cash compensation and up to 36 months of benefits (2.99 times 12 months) if he is terminated under certain change of control circumstances that are described above. The multiplier for the executive officers (other than Mr. Davidson) ranges from 2.0 to 2.5. Thus, each executive officer’s lump sum payment is 2.0 to 2.5 times his or her annual cash compensation and his or her insurance benefits may extend for up to 30 months.

Tax Deductibility of Executive Compensation

      Section 162(m) of the Internal Revenue Code contains provisions that limit the tax deductibility of executive compensation in excess of $1 million per person per year, subject to certain exceptions. The policy of the Company is to design its compensation programs to preserve the tax deductibility of compensation paid to its executive officers and other members of management. However, the Compensation Committee could determine, after taking into consideration the burdens of compliance with Section 162(m) and other relevant facts and circumstances, to pay compensation that is not fully deductible if the committee believes the payments are in the Company’s best interest. In 1997, the stockholders of the Company approved the amended and restated 1992 Plan, allowing compensation paid thereunder in the form of stock options and stock appreciation rights to qualify as “performance-based compensation” for purposes of Section 162(m). In addition, in 2004 the stockholders of the Company approved the material terms of the performance goals applicable to future grants of restricted stock and performance units under the LTIP for the purpose of qualifying payments made pursuant to those grants for deduction under Section 162(m).

Summary

      The members of the Compensation Committee believe that linking executive compensation to corporate performance results in a better alignment of compensation with corporate goals and stockholder interests. As performance goals are met or exceeded, resulting in increased value to stockholders, executive officers are rewarded commensurately. The Compensation Committee believes that compensation levels during 2004 adequately reflect the compensation goals and policies of the Company.

March 18, 2005

      The following “Summary Compensation Table,” “Option Grants in 2004” table, “Aggregated Option Exercises in 2004 and 12/31/04 Option Values” table, “Equity Compensation Plan Table,” “Long Term Incentive Plan Grants in 2004” table, “Pension Plan Table,” and “Performance Graph” are attachments to this Report of the Compensation, Benefits and Stock Option Committee on Executive Compensation.

      The following table sets forth certain summary information concerning the compensation awarded to, earned by or paid to the Chief Executive Officer of the Company and each of the four most-highly compensated executive officers of the Company other than the Chief Executive Officer (collectively, the “named executive officers”) for the years indicated.

Summary Compensation Table

      The following table sets forth certain information with respect to options to purchase common stock granted during the year ended December 31, 2004 to each of the named executive officers.

Option Grants in 2004

      The following table sets forth certain information with respect to the exercise of options to purchase common stock during the year ended December 31, 2004, and the unexercised options held at December 31, 2004 and the value thereof, by each of the named executive officers.

Aggregated Option Exercises in 2004

and 12/31/04 Option Values

      The following table summarizes information regarding the number of shares of common stock of the Company that are outstanding and available for issuance under all of the Company’s existing equity compensation plans as of December 31, 2004.

Equity Compensation Plan Table

      The following table sets forth certain information with respect to performance units granted during the year ended December 31, 2004 to each of the named executive officers. Performance units will be paid in cash based upon the Company’s attainment of specific predetermined multi-year performance targets established by the Compensation Committee. At the end of the performance period ending December 31, 2006, cash payouts will be determined based on the achievement of these targets.

Long Term Incentive Plan Grants in 2004

      The defined benefit plans of the Company that cover its executive officers provide the benefits shown below. The estimates assume that benefits are received in the form of a ten-year certain and life annuity.

Pension Plan Table

      Upon vesting, the amount of retirement benefit depends on an employee’s final average monthly compensation, age and the number of years of credited service (maximum of 30). Final average monthly compensation is defined generally to mean the participant’s average monthly rate of compensation from the Company for the 60 consecutive months prior to retirement that give the highest average monthly rate of compensation for the participant. Compensation covered by the defined benefit plans is defined (with certain exceptions) to mean the compensation actually paid to a participant as reported on the participant’s federal income tax withholding statement for the applicable calendar year. Accordingly, the amounts reported in the Summary Compensation Table included elsewhere in this proxy statement under the section “Annual Compensation” approximate covered compensation for 2004. The amount of benefit shown in the above table is not subject to any deductions for social security or any other offset amounts.

      Under the Company’s qualified defined benefit plan and applicable Internal Revenue Code provisions, as of January 1, 2004, the amount of compensation that can be taken into account under the Company’s qualified defined benefit plan was $205,000 and the maximum annual benefit increased to $165,000. The benefits that accrue in excess of these limitations are paid pursuant to the Company’s nonqualified defined benefit plan.

      As of December 31, 2004, the named executive officers had the following approximate number of years of credited service for retirement purposes: Mr. Davidson — 4; Ms. Cunningham —3 ; Mr. Poillion — 28; Mr. McElvany — 26; and Mr. Stover — 2.

      Under the Company’s nonqualified Deferred Compensation Plan, the named executive officers are eligible to defer portions of the salary and bonus reflected on the Summary Compensation Table above and to receive certain matching contributions that would have been made to the Company’s qualified 401(k) plan if the plan had not been subject to Internal Revenue Code compensation and contribution limitations. The matching contributions and interest earnings credited to the Deferred Compensation Plan accounts of the named executive officers are reflected in the All Other Compensation column of the Summary Compensation Table above.

      The following graph sets forth the cumulative total stockholder return for the Company’s common stock, the S&P 500 Index, the Dow Jones Total Return Index for Secondary Oil Companies, and a Company peer group, for the years indicated as prescribed by the SEC’s rules.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

      Section 16(a) of the Exchange Act requires directors and officers of the Company, and persons who beneficially own more than 10 percent of the Company’s common stock, to file with the SEC initial reports of ownership and reports of changes in ownership of the common stock. Directors, officers and more than 10 percent stockholders are required by SEC regulations to furnish the Company with copies of all Section 16(a) forms they file.

      To the Company’s knowledge, based solely on a review of the copies of the reports furnished to the Company and written representations that no other reports were required, all Section 16(a) filing requirements applicable to its directors, officers and more than 10 percent beneficial owners were complied with during the year ended December 31, 2004.

CERTAIN TRANSACTIONS

      In the ordinary course of its business, the Company purchases products or services from, or engages in other transactions with, various third parties. Occasionally, these transactions may involve entities that are affiliated with one or more members of the Board of Directors. When they occur, these transactions are conducted in the ordinary course and on an arms-length basis.

      During 2004, the Company paid approximately $105,633 to The Samuel Roberts Noble Foundation, Inc., principally relating to reimbursement of expenses for the Company’s use of an aircraft owned by the Foundation. The Company received payments from the Foundation of approximately $13,346 for aircraft usage. Michael A. Cawley is President and Chief Executive Officer of the Foundation, and a trustee of the Foundation.

REPORT OF THE

AUDIT COMMITTEE

To the Stockholders of

Noble Energy, Inc.:

      The primary purpose of the Audit Committee of the Company’s Board of Directors is to: (1) assist the Board of Directors in fulfilling its responsibility to oversee the integrity of the Company’s financial statements, the Company’s compliance with legal and regulatory requirements, the independent auditor’s qualifications and independence, and the performance of the Company’s internal audit function and independent auditor and (2) prepare a committee report as required by the SEC to be included in the Company’s annual proxy statement. The Audit Committee’s function is more fully described in its charter, which the Audit Committee and the Board of Directors adopted on March 4, 2004 and amended on January 25, 2005 in connection with the Audit Committee’s annual review of its charter. A copy of the charter is available in the “Corporate Governance” section of the Company’s website at www.nobleenergyinc.com. The Audit Committee held fourteen meetings during 2004, including regular meetings and special meetings addressing earnings releases and compliance with Section 404 of the Sarbanes-Oxley Act of 2002.

      Throughout 2004 and continuing to date, the Audit Committee has been comprised entirely of independent directors, as defined and required by the federal securities laws and the applicable listing standards of the NYSE and as so determined by the Company’s Board of Directors. In making this determination, the Board of Directors of the Company considered Mr. Cawley’s continuing service as President and Chief Executive Officer of The Samuel Roberts Noble Foundation, Inc., a not-for-profit corporation that owned approximately 2.3% of the Company’s stock at the time (January 25, 2005) of the Board determination. The Board of Directors also reviewed the business relationship between the Company and the Foundation and concluded that this relationship was not material and would not interfere with Mr. Cawley’s exercise of independent judgment for purposes of the NYSE’s audit committee independence requirements. As a result of its review, the Board of Directors determined that it was in the best interest of the Company and its shareholders for Mr. Cawley to serve as a member of the Company’s Audit Committee.

      The Board of Directors elected Dale P. Jones as the Chair of the Audit Committee, effective April 27, 2004, and, effective upon Mr. Jones’ death on November 6, 2004, elected Bruce A. Smith as the successor Chair of the Audit Committee. The Board of Directors determined that Mr. Smith is both independent and an “audit committee financial expert” as defined by SEC guidelines.

Review and Discussion

      The Audit Committee has reviewed and discussed the Company’s audited financial statements with management. It has also discussed with KPMG LLP, the Company’s independent auditors, the matters required to be discussed by Statement of Auditing Standards No. 61 (Communication with Audit Committees), as amended by SAS No. 90 (Audit Committee Communications). Additionally, KPMG LLP has provided to the Audit Committee the written disclosures required by Independence Standards Board Standard No. 1 Independence Discussions with Audit Committees, and the committee discussed the auditors’ independence with management and the auditors.

      The Audit Committee also has considered whether KPMG LLP’s rendering of non-audit services to the Company is compatible with maintaining its independence. The Audit Committee has concluded that the rendering of the non-audit services by KPMG LLP has not impaired its independence.

      Based on the Audit Committee’s discussions with management and the independent auditors, and its review of the representations of management and the report of KPMG LLP to the Audit Committee, the Audit Committee recommended to the Board of Directors the inclusion of the audited consolidated financial statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2004, as filed with the SEC.

MATTERS RELATING TO THE INDEPENDENT AUDITORS

Fees Paid to the Independent Public Accountants for Fiscal Years 2004 and 2003

Audit Committee Pre-Approval Policies and Procedures

      The Audit Committee pre-approves all audit and non-audit services by an independent auditor prior to the receipt of such services. The Audit Committee Chair has the authority to pre-approve non-audit related services of up to $25,000 rendered by the Company’s independent auditor. Any pre-approval of non-audit services by the Audit Committee Chair shall be reported to the Audit Committee at its next scheduled meeting.

      All audit-related services, tax services and other services for 2004 set forth in the table above were pre-approved by the Audit Committee Chair or the Audit Committee, as provided above, which in either case determined that such services would not impair the independence of the auditor and are consistent with the SEC’s rules on auditor independence.

STOCKHOLDER PROPOSALS AND OTHER MATTERS

      Stockholder proposals intended to be brought before the annual meeting of stockholders as an agenda item or to be included in the Company’s proxy statement relating to the 2006 annual meeting of stockholders, which is currently scheduled to be held on April 25, 2006, must be received by the Company at its office in Houston, Texas, addressed to the Secretary of the Company, no later than November 24, 2005.

      The cost of solicitation of proxies will be borne by the Company. Solicitation may be made by mail, personal interview, telephone or telegraph by officers, agents or employees of the Company, who will receive no additional compensation therefor. To aid in the solicitation of proxies, the Company has employed the firm of Georgeson & Co., Inc., which will receive a fee of approximately $7,500 plus out-of-pocket expenses. The Company will bear the reasonable expenses incurred by banks, brokerage firms, custodians, nominees and fiduciaries in forwarding proxy material to beneficial owners.

      The Board of Directors does not intend to present any other matter at the meeting and knows of no other matters that will be presented. However, if any other matter comes before the meeting, the persons named in the enclosed proxy intend to vote thereon in accordance with their best judgment.

Administration

      The Plan shall be administered by the Board of Directors. Subject to the express provisions of the Plan, the Board of Directors shall have the authority, in its discretion, to (a) determine which Non-Employee Directors will be granted Options and Stock Awards, (b) determine the number of shares of Common Stock to be made subject to each Option or Stock Award, (c) determine the exercise price for the shares of Common Stock to be made subject to each Option (which exercise price per share shall not be less than the Fair Market Value of such share on the date such Option is granted), (d) determine the period within which each Option may be exercised (which exercise period shall not exceed ten years from the date such Option is granted), (e) determine the restrictions (including forfeiture restrictions), terms and conditions to be applicable to each Option or Stock Award, (f) construe and interpret the provisions of the Plan and any agreement evidencing an Option or Stock Award, (g) amend the agreement evidencing the grant of any Option or Stock Award to accelerate its exercisability or the lapse of its restrictions or otherwise modify the restrictions, terms and conditions applicable to such Option or Stock Award, and (h) adopt such rules and procedures, appoint such agents and take all such other action as the Board of Directors may deem to be necessary or appropriate for the proper administration of the Plan. The decisions of the Board of Directors with respect to the Plan and any Option or Stock Award shall be final and binding upon the Company, the Holders and Awardees, and all other persons having or claiming to have an interest in the Plan or an Option or Stock Award granted pursuant to the Plan. No member of the Board of Directors shall incur any liability by reason of any action taken or omitted in good faith with respect to the Plan or an Option or Stock Award granted pursuant to the Plan.

ARTICLE III

Options

      3.01     Grant of Options. Each new Non-Employee Director shall be granted an option to purchase 5,600 shares of Common Stock on the date of his or her election to the Board of Directors as a director. On each February 1 after the Effective Date, each incumbent Non-Employee Director shall be granted an option

to purchase 1,400 shares of Common Stock. In addition to the foregoing automatic grants of Options, at any time and from time to time the Board of Directors in its discretion may grant an additional Option to any Non-Employee Director who previously has received or concurrently is receiving a February 1 automatic Option grant; provided, however, that the aggregate number of shares of Common Stock that may be subject to Options granted pursuant to this sentence to a particular Non-Employee Director during any calendar year, when added to the number of shares of Common Stock that are subject to the Option automatically granted to such Non-Employee Director on February 1 of that year, shall not exceed 5,600. Each Option granted pursuant to the Plan shall be subject to the restrictions, terms and conditions set forth in Section 3.02 below, and to such other restrictions (including forfeiture restrictions), terms and conditions not inconsistent therewith or with the other provisions of the Plan as shall be determined by the Board of Directors in its discretion at the time of the granting of such Option.

      3.02     Option Terms and Agreement. The price at which each share of Common Stock that is subject to an Option may be purchased shall be the Fair Market Value of such share on the date of the grant of such Option. Each Option shall be exercisable from time to time over the period of time commencing one year from the date of the grant of such Option and ending, unless terminated earlier pursuant to the provisions of Section 3.02(a) hereof, (a) in the case of an Option automatically granted under the Plan, upon the expiration of ten years from the date of such grant, or (b) in the case of an Option granted by the Board of Directors in its discretion, upon the expiration date specified for such Option by the Board of Directors at the time of the grant of such Option; provided, however, that each Option granted to a Holder shall become exercisable in full upon the death of the Holder or upon the mandatory retirement of the Holder as a regular director because of age in accordance with Article III of the By-laws of the Company. Each Option granted under the Plan shall be evidenced by a written agreement entered into by the Company and the Non-Employee Director to whom the Option is granted, which agreement shall be in such form as the Board of Directors may prescribe, and shall include, incorporate or conform to the following terms and conditions, and such other terms and conditions not inconsistent therewith or with the other provisions of the Plan, as the Board of Directors may deem to be appropriate:

ARTICLE IV

Stock Awards

      4.01     Grant of Stock Awards. Each new Non-Employee Director shall be granted a Stock Award of 2,400 shares of Common Stock on the date of his or her election to the Board of Directors as a director. On each February 1 after the Effective Date, each incumbent Non-Employee Director shall be granted a Stock Award of 600 shares of Common Stock. In addition to the foregoing automatic grants of Stock Awards, at any time and from time to time the Board of Directors may grant an additional Stock Award to any Non-Employee Director who previously has received or concurrently is receiving a February 1 automatic Stock Award grant; provided, however, that the aggregate number of shares of Common Stock that may be subject to Stock Awards granted pursuant to this sentence to a particular Non-Employee Director during any calendar year, when added to the number of shares of Common Stock that are subject to the Stock Award automatically granted to such Non-Employee Director on February 1 of that year, shall not exceed 2,400.

Each Stock Award granted pursuant to the Plan shall be subject to the restrictions, terms and conditions set forth in Sections 4.02 and 4.03 below, and to such other restrictions (including forfeiture restrictions), terms and conditions not inconsistent therewith or with the other provisions of the Plan as shall be determined by the Board of Directors in its discretion at the time of the granting of such Stock Award.

      4.02      Stock Award Restrictions. The shares of Common Stock granted under each Stock Award shall be restricted for a period of at least one year from the date of the grant of such Stock Award. No share of Common Stock granted under a Stock Award may be sold, assigned, transferred, discounted, exchanged, pledged or otherwise encumbered or disposed of until all of the restrictions, terms and conditions applicable to such shares have been satisfied. Each Stock Award granted under the Plan shall be evidenced by a written agreement entered into by the Company and the Non-Employee Director to whom the Stock Award is granted, which agreement shall be in such form as the Board of Directors may prescribe, and shall include, incorporate or conform to the following terms and conditions, and such other terms and conditions not inconsistent therewith or with the other provisions of the Plan, as the Board of Directors may deem to be appropriate:

      4.03     Additional Conditions. An Awardee shall be the record owner of the shares of Common Stock granted under a Stock Award and shall have all the rights of a stockholder with respect to such shares, including the right to vote and the right to receive dividends or other distributions made or paid with respect to such shares. During the Restricted Period applicable to the shares of Common Stock granted under a Stock Award, the certificate or certificates representing such shares shall bear a legend similar to the following:

      In order to enforce the restrictions, terms and conditions that are applicable to the shares of Common Stock granted under a Stock Award, the Board of Directors may require the Awardee thereof, upon the receipt of a certificate or certificates representing such shares, or at any time thereafter during the Restricted Period applicable to such Stock Award, to deposit such certificate or certificates, together with stock powers and other instruments of transfer, appropriately endorsed in blank, with the Company or an escrow agent designated by the Company under an escrow agreement in such form as by the Board of Directors shall prescribe. After the satisfaction of the restrictions, terms and conditions applicable to such shares, a new certificate, without the legend set forth above, for the number of shares that are no longer subject to such restrictions, terms and conditions shall be delivered to the Awardee. Any provision of this Plan to the contrary notwithstanding, the Board of Directors shall have the authority in its discretion to cancel at any time all or

any portion of any outstanding restrictions, terms and conditions applicable to all or any portion of the shares of Common Stock granted under a Stock Award.

ARTICLE V

Authorized Common Stock

      5.01     Common Stock. The total number of shares of Common Stock as to which Options and Stock Awards may be granted pursuant to the Plan shall be 400,000, in the aggregate, except as such number of shares shall be adjusted from and after the Effective Date in accordance with the provisions of Section 5.02 hereof. If any outstanding Option under the Plan shall expire or be terminated for any reason before the end of the exercise period applicable to such Option, the shares of Common Stock allocable to the unexercised portion of such Option may again be subject to the Plan. The Company shall, at all times during the existence of outstanding Options, retain as authorized and unissued shares of Common Stock at least the number of shares from time to time subject to the outstanding Options or otherwise assure itself of its ability to perform its obligation under the Plan.

      5.02     Adjustments Upon Changes in Common Stock. In the event the Company shall effect a split of the outstanding shares of Common Stock or pay a dividend in shares of Common Stock, or in the event the outstanding shares of Common Stock shall be combined into a smaller number of shares, (a) the number of shares of Common Stock that will be subject to Options or Stock Awards granted automatically pursuant to the provisions of Section 3.01 or 4.01 hereof, (b) the aggregate number of shares of Common Stock that may be subject to Options or Stock Awards granted automatically and by the Board of Directors in its discretion to a particular Non-Employee Director during any calendar year pursuant to the provisions of Section 3.01 or 4.01 hereof, and (c) the maximum number of shares of Common Stock as to which Options and Stock Awards may be granted under the Plan as provided in Section 5.01 hereof, shall be increased or decreased proportionately. In the event that before delivery by the Company of all of the shares of Common Stock in respect of which any Option has been granted under the Plan, the Company shall have effected such a split, dividend or combination, the shares still subject to the Option shall be increased or decreased proportionately and the purchase price per share shall be increased or decreased proportionately so that the aggregate purchase price for all of the then optioned shares shall remain the same as immediately prior to such split, dividend or combination. In the event of a reclassification of the shares of Common Stock not covered by the foregoing, or in the event of a liquidation or reorganization, including a merger, consolidation or sale of assets, the Board of Directors of the Company shall make such adjustments, if any, as it may deem appropriate in the number, purchase price and kind of shares covered by the unexercised portions of Options theretofore granted under the Plan. The provisions of this Section 5.02 shall only be applicable if, and only to the extent that, the application thereof does not conflict with any valid governmental statute, regulation or rule.

ARTICLE VI

General Provisions

      6.01     Change in Control. If a Change in Control occurs while an Option is outstanding, such Option shall become exercisable in full. If a Change in Control occurs during the Restricted Period applicable to a Stock Award, all of the restrictions, terms and conditions applicable to the shares of Common Stock granted under such Stock Award shall terminate, and such shares shall be delivered to the Awardee of such Stock Award free of such restrictions, terms and conditions. For the purposes of this Plan, a “Change in Control” shall be deemed to have occurred if:

Notwithstanding the foregoing, a “Change in Control” of the Company shall not be deemed to have occurred for purposes of subparagraph (d) of this Section 6.01 solely as the result of an acquisition of securities by the Company which, by reducing the number of shares of Common Stock or other Voting Securities of the Company outstanding, increases (i) the proportionate number of shares of Common Stock beneficially owned by any person to twenty-five percent (25%) or more of the shares of Common Stock then outstanding or (ii) the proportionate voting power represented by the Voting Securities of the Company beneficially owned by any person to twenty-five percent (25%) or more of the combined voting power of all then outstanding Voting Securities; provided, however, that if any person referred to in clause (i) or (ii) of this sentence shall thereafter become the beneficial owner of any additional shares of Common Stock or other Voting Securities of the Company (other than a result of a stock split, stock dividend or similar transaction), then a Change in Control of the Company shall be deemed to have occurred for purposes of subparagraph (d) of this Section 6.01.

      6.02     Termination of the Plan. The Board of Directors shall have the right and power to terminate this Plan at any time. If not sooner terminated by such action of the Board of Directors, the Plan shall terminate at the close of business on March 31, 2015. No Option or Stock Award shall be granted under the Plan after its termination. Except as otherwise provided in Section 6.05 hereof, after the termination of the Plan an Option or Stock Award that has been granted prior to such termination shall remain in effect in accordance with the provisions of the agreement evidencing such Option or Stock Award.

      6.03     Amendment of the Plan. Subject to the limitations set forth in this Section 6.03, the Board of Directors may at any time and from time to time amend, modify or suspend the Plan. No such amendment, modification or suspension shall (a) adversely affect an Option or Stock Award theretofore granted to any Holder or Awardee, or deprive any Holder or Awardee of any shares of Common Stock he or she has acquired or may acquire under such an Option or Stock Award, without his or her written consent, or (b) be made without the approval of the stockholders of the Company if such amendment, modification or suspension would (i) expand the types of grants or awards that may be made under the Plan, (ii) increase the total number of shares of Common Stock that may be granted under the Plan or decrease the exercise price of Options granted or to be granted under the Plan (other than as provided in Section 5.02 hereof), (iii) materially expand the class of persons eligible to be granted Options or Stock Awards under the Plan,

(iv) materially increase the benefits accruing to Holders or Awardees under the Plan, (v) extend the term of the Plan or the exercise period applicable to an Option, or (vi) constitute a material revision of the Plan requiring stockholder approval under the New York Stock Exchange Corporate Governance Listing Standards or applicable law.

      6.04     Treatment of Proceeds. Proceeds from the sales of Common Stock pursuant to the exercise of Options shall constitute general funds of the Company.

      6.05     Effectiveness. This Plan shall be submitted for approval by the stockholders of the Company at their 2005 regular meeting. The Plan shall become effective on the date the Plan is approved at such meeting. Any provision of the Plan to the contrary notwithstanding, no Option or Stock Award shall be granted prior to obtaining such stockholder approval. If the Plan is not so approved by the stockholders of the Company, the Plan shall be null and void.

      6.06     Termination of 1988 Plan. This Plan is intended to supersede and replace the 1988 Nonqualified Stock Option Plan for Non-Employee Directors of Noble Energy, Inc., as amended (the “1988 Plan”). The 1988 Plan shall terminate on the date the Plan is approved by the stockholders of the Company in accordance with the provisions of Section 6.05 hereof.

      IN WITNESS WHEREOF, the undersigned has executed this Plan on this            day of                     , 2005.
