SEAGULL ENERGY CORPORATION 1986 STOCK OPTION PLAN (RESTATED) I. History and Purpose of the Plan The Seagull Energy Corporation 1986 Stock Option Plan (the "Plan") was originally adopted by Seagull Energy Corporation, a Texas corporation (the "Company"), on February3, 1986 and was approved by the shareholders of the Company on May 13, 1986. The Plan is intended to provide a means whereby certain employees of the Company and its subsidiaries may develop a sense of proprietorship and personal involvement in the development and financial success of the Company, and to encourage them to remain with and devote their best efforts to the business of the Company, thereby advancing the interests of the Company and its shareholders. Accordingly, the Company may grant to certain employees the option ("Option") to purchase shares ofthe common stock of the Company ("Stock"), as hereinafter set forth. Options granted under the Plan may be either incentive stock options, within the meaning ofsection 422A(b) of the Internal Revenue Code of 1986, as amended (the "Code"),("Incentive Stock Options") or options which do not constitute Incentive Stock Options. On September 20, 1988, the Company restated the Plan in the form of this Seagull Energy Corporation 1986 Stock Option Plan (Restated) for the purpose of incorporating certain amendments previously adopted with respect to the Plan into the text of the Plan and for purposes of amending the Plan in certain respects. The terms and provisions of this restatement of the Plan are effective only with respect to Options granted from and after September 20, 1988 and Options granted prior to such date shall continue to be governed by the terms and provisions of the Plan (and amendments thereto) as in effect on September 20, 1988. II. Administration The Plan shall be administered by the Compensation Committee (the "Committee") of the Board of Directors of the Company (the "Board"). Members of the Committee shall not be eligible, and shall not have been eligible at any time within one year prior to their appointment to the Committee, to participate in the Plan or in any other stock, stock option or stock appreciation rights plan of the Company or any of its affiliates ("Company Stock Plan"). The Committee shall have sole authority to select the individuals who are to be granted Options from among those eligible hereunder and to establish the number of shares which may be issued under each Option. TheCommittee is authorized to interpret the Plan and may from time to time adopt such rules and regulations, consistent with the provisions of the Plan, as it may deem advisable to carry out the Plan. All decisions made by the Committee in selecting the individuals to whom Options shall be granted, in establishing the number of shares which may be issued under each Option and in construing the provisions of the Plan shall befinal. III. Option Agreements Each Option shall be evidenced by an Option Agreement and shall contain such terms and conditions, and may be exercisable for such periods, as may be approved by the Committee. The terms and conditions of the respective Option Agreements need not be identical. Specifically, an Option Agreement may provide for the surrender of the right to purchase shares under the Option in return for a payment in cash or shares of Stock or a combination of cash and shares of Stock equal in value to the excess of the fair market value of the shares with respect to which the right to purchase is surrendered over the option price therefor ("Stock Appreciation Rights"), on such terms and conditions as the Committee in its sole discretion may prescribe; provided, that with respect to Stock Appreciation Rights granted to employees who are subject to Section 16 of the Securities Exchange Act of 1934 (the "1934 Act"), except as provided in Subparagraph VIII(c) hereof, the Committee shall retain final authority (i) to determine whether an optionee shall be permitted, or (ii) to approve an electionby an optionee, to receive cash in full or partial settlement of Stock Appreciation Rights. Moreover, an Option Agreement may provide for the payment of the option price, in whole or in part, by the delivery of a number of shares of Stock (plus cash ifnecessary) having a fair market value equal to such option price. Finally, an Option Agreement may provide for cash less exercise by permitting an Optionee to withhold from shares of Stock acquirable upon exercise of such Option shares of Stock equal in value to all or a specified portion of the Option Price; all on such terms and subject to such conditions as shall be established from time to time by the Committee. For all purposes under the Plan, the fair market value of a share of Stock on a particular date shall be equal to the closing price of the Stock on the New York Stock Exchange Composite Tape on that date, or if no prices are reported on that date, on the last preceding date on which such prices of the Stock are so reported. Each Option and all rights granted thereunder shall not be transferable other than by will or the laws of descentand distribution, and shall be exercisable during the optionee's lifetime only by the optionee or the optionee's guardian or legal representative. IV. Eligibility of Optionee Options may be granted only to individuals who are key employees (including officers and directors who are also key employees) of the Company or any parent orsubsidiary corporation (as defined in section 425 of the Code) of the Company at the time the Option is granted. Options may be granted to the same individual on more than one occasion. No Incentive Stock Option shall be granted to an individual if, atthe time the Option is granted, such individual owns stock possessing more than 10%of the total combined voting power of all classes of stock of the Company or of its parent or subsidiary corporation, within the meaning of section 422A(b)(6) of the Code, unless (i)at the time such Option is granted the option price is at least 110% of thefair market value of the Stock subject to the Option and (ii)such Option by its terms is not exercisable after the expiration of five years from the date of grant. To the extent that the aggregate fair market value (determined at the time the respective Incentive Stock Option is granted) of stock with respect to which Incentive Stock Options granted after 1986 are exercisable for the first time by an individual during any calendar year under all incentive stock option plans of the Company and its parent andsubsidiary corporations exceeds $100,000, such Incentive Stock Options shall be treatedas options which do not constitute Incentive Stock Options. The Committee shall determine, in accordance with applicable provisions of the Code, Treasury Regulations and other administrative pronouncements, which of an optionee's Incentive Stock Options will not constitute Incentive Stock Options because of such limitation and shall notify the optionee of such determination as soon as practicable after such determination. V. Shares Subject to the Plan The aggregate number of shares which may be issued under Options granted under the Plan shall not exceed 300,000 shares of Stock. Such shares may consist of authorized but unissued shares of Stock or previously issued shares of Stock reacquired by the Company. Any of such shares which remain unissued and which are not subject to outstanding Options at the termination of the Plan shall cease to be subject to the Plan, but, until termination of the Plan, the Company shall at all times make available a sufficient number of shares to meet the requirements of the Plan. Should any Option here under expire or terminate prior to its exercise in full, the shares theretofore subject to such Option may again be subject to an Option granted under the Plan. The aggregate number of shares which may be issued under the Plan shall be subjectto adjustment in the same manner as provided in Paragraph VIII hereof with respect to shares of Stock subject to Options then outstanding. Exercise of an Option in any manner, including an exercise involving a Stock Appreciation Right, shall result in a decrease in the number of shares of Stock which may thereafter be available, both for purposes of the Plan and for sale to any one individual, by the number of shares as to which the Option is exercised. Separate stock certificates shall be issued by the Company for those shares acquired pursuant to the exercise of an Incentive Stock Option and for those shares acquired pursuant to the exercise of any Option which does not constitute an Incentive Stock Option. VI. Option Price The purchase price of Stock issued under each Option shall be determined by the Committee, but in the case of an Incentive Stock Option, such purchase price shall not be less than the fair market value of Stock subject to the Option on the date the Option is granted. VII. Term of Plan The Plan became effective upon February 3, 1986, the date of its adoption by the Board. Except with respect to Options then outstanding, if not sooner terminated under the provisions of Paragraph IX, the Plan shall terminate upon and no further Options shall be granted after the expiration of ten years from the date of its adoption by the Board. VIII. Recapitalization or Reorganization (a) The existence of the Plan and the Options granted hereunder shall notaffect in any way the right or power of the Board or the shareholders of the Company to make or authorize any adjustment, recapitalization, reorganization or other change inthe Company's capital structure or its business, any merger or consolidation of the Company, any issue of debt or equity securities ahead of or affecting Stock or the rights thereof, the dissolution or liquidation of the Company or any sale, lease, exchange or other disposition of all or any part of its assets or business or any othercorporate act or proceeding. (b) The shares with respect to which Options may be granted are shares of Stock as presently constituted, but if, and whenever, prior to the expiration of an Option theretofore granted, the Company shall effect a subdivision or consolidation of shares of Stock or the payment of a stock dividend on Stock without receipt of consideration by the Company, the number of shares of Stock with respect to which such Option may thereafter be exercised (i)in the event of an increase in the number of outstanding shares shall be proportionately increased, and the purchase price per shareshall be proportionately reduced, and (ii)in the event of a reduction in the number of outstanding shares shall be proportionately reduced, and the purchase price per shareshall be proportionately increased. (c) If the Company recapitalizes or otherwise changes its capital structure, thereafter upon any exercise of an Option theretofore granted the optionee shall be entitled to purchase under such Option, in lieu of the number of shares of Stock as to which such Option shall then be exercisable, the number and class of shares of stockand securities to which the optionee would have been entitled pursuant to the terms of the recapitalization if, immediately prior to such recapitalization, the optionee had been the holder of record of the number of shares of Stock as to which such Option is then exercisable. If (i) the Company shall not be the surviving entity in any merger or consolidation (or survives only as a subsidiary of an entity other than a previously wholly owned subsidiary of the Company), (ii) the Company sells, leases or exchanges or agrees to sell, lease or exchange all or substantially all of its assets to any other person or entity (other than a wholly-owned subsidiary of the Company), (iii) the Company is to be dissolved and liquidated, (iv) any person or entity, including a "group" as contemplated by Section 13(d)(3) of the 1934 Act, acquires or gains ownership or control (including, without limitation, power to vote) of more than 40% of the outstanding shares of Stock, or (v) as a result of or in connection with a contested election of directors, the persons who were directors of the Company before such election shall cease to constitute a majority of the Board (each such event is referred to herein as a"Corporate Change"), then, upon the occurrence of any such Corporate Change, each Option then outstanding shall become fully exercisable and effective as of a date (selected by the Committee) within (a) ten days after the approval by the shareholders of the Company of such merger, consolidation, sale, lease or exchange of assets or dissolution or such election of directors or (b) thirty days of such change of control, the Committee, acting in its sole discretion without the consent or approval of any optionee, shall effect one or more of the following alternatives, which may vary among individual optionees: (1) establish a limited period of time on or before a specified date (beforeor after such Corporate Change) fixed by the Committee during which such outstanding Options may be exercised, after which specified date all unexercised Options and allrights of optionees thereunder shall terminate, (2) require the mandatory surrender tothe Company by selected optionees of some or all of the outstanding Options held by such optionees as of a date, before or after such Corporate Change, specified by the Committee, in which event the Committee shall thereupon cancel such Options and pay to each optionee an amount of cash per share equal to the excess of the amount calculated in Subparagraph (d) below (the "Change of Control Value") of the shares subject to such Option over the exercise price(s) under such Options for such shares, (3) make such adjustments to Options then outstanding as the Committee deems appropriate to reflect such Corporate Change (provided, however, that the Committee may determinein its sole discretion that no adjustment is necessary to Options then outstanding) (4) provide that thereafter upon any exercise of an Option theretofore granted the optionee shall be entitled to purchase under such Option, in lieu of the number of shares of Stock as to which such Option shall then be exercisable, the number and class of shares of stock or other securities or property to which the optionee would have been entitled pursuant to the terms of the agreement of merger, consolidation or sale of assets and dissolution if, immediately prior to such merger, consolidation or sale of assets and dissolution the optionee had been the holder of record of the number of shares of Stock as to which such Option is then exercisable. (d) For the purposes of clause (2) in Subparagraph (c) above, the "Change of Control Value" shall equal the amount determined in clause (i), (ii) or (iii), whichever is applicable, as follows: (i) the per share price offered to shareholders of the Company in any such merger, consolidation, sale of assets or dissolution transaction, (ii) the price per share offered to shareholders of the Company in any tender offer or exchange offer whereby a Corporate Change takes place, or (iii) if such Corporate Change occurs other than pursuant to a tender or exchange offer, the fair market value per shareof the shares into which such Options being surrendered are exercisable, as determined by the Committee as of the date determined by the Committee to be the date of cancellation and surrender of such Options. In the event that the consideration offered to shareholders of the Company in any transaction described in this Subparagraph (d) or Subparagraph (c) above consists of anything other than cash, the Committee shall determine the fair cash equivalent of the portion of the consideration offered which is other than cash.
