Exhibit 10.16 EXHIBIT B AMENDED AND RESTATED 1994 NONEMPLOYEE DIRECTOR STOCK OPTION PLAN of CABOT OIL & GAS CORPORATION 1. Purpose of the Plan. This Nonemployee Director Stock Option Plan (the "Plan") is intended as an incentive to retain and attract persons of training, experience and ability to serve as independent directors on the Board of Directors of Cabot Oil & Corporation, a Delaware corporation (the "Company"), to encourage the sense of proprietorship of such persons and to stimulate the active interest of such persons in the development and financial success of the Company. It is further intended that the options granted pursuant to this Plan (the "Options") will be nonqualified options within the meaning of Section 83 of the Internal Revenue Code of 1986, as amended (the "Code"). 2. Stockholder Approval. All Options granted pursuant to this Plan are subject to, and may not be exercised before, the approval of this Plan by the affirmative vote of the holders of a majority of the outstanding shares of the Class A Common Stock, par value $.10 per share (the "Common Stock"), of the Company that are present, or represented, and entitled to vote at a meeting of the Company's stockholders. 3. Designation of Participants; Automatic Grant of Options. Each director of the Company who is not an employee of the Company or any Subsidiary (as hereinafter defined) of the Company (any such director being hereinafter referred to as a "Nonemployee Director") shall be granted Options as described hereunder. Each individual who becomes a Nonemployee Director after the Effective Date shall automatically be granted Options to purchase 10,000 shares of Common Stock (subject to adjustment as provided in Paragraph 10) on the date such person first becomes a Nonemployee Director. Furthermore, at each annual meeting of stockholders (other than when the director's status as such terminates at such meeting), each Nonemployee Director shall automatically be granted Options to purchase an additional 5,000 shares of Common Stock (subject to adjustment as provided in Paragraph 10) on such date. Notwithstanding the foregoing, in the case of any grant of Options made on a date subsequent to the Effective Date, such grant shall only be made if the number of shares subject to future grant under this Plan is sufficient to make all automatic grants required to be made pursuant to this Plan on such date of grant. As used herein, the term "Subsidiary" of the Company shall mean any corporation of which the Company directly or indirectly owns shares representing more than 50% of the voting power of all classes or series of capital stock of such corporation which have the right to vote generally on matters submitted to a vote of the stockholders of such corporation. 4. Option Agreement. Each Option granted hereunder shall be embodied in a written option agreement ("Option Agreement"), which shall be subject to the terms and conditions set forth herein and shall be signed by the Optionee and by the Chief Executive Officer, the Chief Operating Officer, or any Vice President of the Company for and on behalf of the Company. 5. Common Stock Reserved for the Plan. Subject to adjustment as provided in Paragraph 10 hereof, a total of 300,000 shares of Common Stock shall be reserved for issuance upon the exercise of Options granted pursuant to this Plan. The shares subject to the Plan shall consist of unissued shares or previously issued shares reacquired and held by the Company, or any parent or subsidiary of the Company, in its treasury. The Board of Directors and the appropriate officers of the Company shall from time to time take whatever actions are necessary to execute, acknowledge, file and deliver any documents required to be filed with or delivered to any governmental authority or any stock exchange or transaction reporting system on which shares of Common Stock are listed or quoted in order to make shares of Common Stock available for issuance to an Optionee (as hereinafter defined) 71 pursuant to this Plan. Common Stock subject to Options that are forfeited or terminated or expire unexercised in such a manner that all or some of the shares subject thereto are not issued to an Optionee shall immediately become available for the granting of Options. As used herein, the term "Optionee" shall mean any Nonemployee Director to whom Options are granted hereunder. 6. Option Price. (a) The purchase price of each share of Common Stock that is subject to an Option granted pursuant to this Plan shall be 100% of the Fair Market Value of such share of Common Stock on the date the Option is granted. (b) The Fair Market Value of a share of Common Stock on a particular date shall be deemed to be (i) if the shares of Common Stock are listed on a national securities exchange, the average of the highest and lowest sales price per share of Common Stock on the principal such national securities exchange on that date, or, if there shall have been no such sale so reported on that date, on the last preceding date on which such a sale was so reported, (ii) if the shares of Common Stock are not so listed but are quoted in the NASDAQ National Market System, the average of the highest and lowest sales price per share of Common Stock on the NASDAQ National Market System on that date, or, if there shall have been no such sale so reported on that date, on the last preceding date on which such a sale was so reported or (iii) if the Common Stock is not so listed or quoted, the average of the closing bid and asked price on that date, or, if there are no quotations available for such date, on the last preceding date on which such quotations shall be available, as reported by NASDAQ, or, if not reported by NASDAQ, by the National Quotation Bureau, Inc. 7. Option Period. Each Option granted pursuant to this Plan shall terminate and be of no force and effect with respect to any shares of Common Stock not purchased by the Optionee upon the earliest to occur of the following: (a) the expiration of five years following the date upon which the Option is granted; (b) the expiration of one year following the date upon which the Optionee ceases to be a Nonemployee Director by reason of death, disability or mandatory retirement; or (c) the expiration of three months following the date on which the Optionee ceases to be a Nonemployee Director for any reason other than death, disability or mandatory retirement. 8. Exercise of Options. (a) Options granted pursuant to this Plan shall be exercisable, on a cumulative basis, as follows: (i) with respect to 33 1/3% of the total number of shares of Common Stock initially subject to any Option, such Option shall be exercisable on the first anniversary of the date of grant; and (ii) with respect to the remaining shares of Common Stock subject to any Option, such Option shall be exercisable with respect to an additional 33 1/3% of the total number of shares initially subject thereto as of the second and third anniversaries of the date of the grant. (b) An Option may be exercised solely by the Optionee during his lifetime or after his death by the person or persons entitled thereto under his will or the laws of descent and distribution. (c) In the event that an Optionee ceases to serve as a Nonemployee Director for any reason other than death, disability or mandatory retirement, an Option granted to such Optionee may be exercised only to the extent such Option was exercisable at the time he ceased to serve in such capacity. (d) In the event that an Optionee ceases to serve as a Nonemployee Director by reason of death, disability or mandatory retirement, at a time when an Option granted hereunder is still in force and unexpired under the terms of Paragraph 7 hereof, each such unmatured Option shall be accelerated. Such acceleration shall be effective as of the date of death, disability or retirement, as appropriate, and each Option so accelerated shall be exercisable in full for so long as it is still in force and unexpired under the terms of Paragraph 7 hereof. 72 (e) The purchase price of the shares as to which an Option is exercised shall be paid in full at the time of the exercise. Such purchase price shall be payable in cash or by means of tendering theretofore owned Common Stock which has been held by the Optionee for more than six months, valued at Fair Market Value on the date of exercise, or any combination thereof. An Optionee may also exercise an Option by use of the proceeds to be received from the sale of Common Stock issuable pursuant to the Option. No holder of an Option shall be, or have any of the rights or privileges of, a stockholder of the Company in respect of any shares subject to any Option unless and until certificates evidencing such shares shall have been issued by the Company to such holder. 9. Assignability. No Option shall be assignable or otherwise transferable except by will or the laws of descent and distribution or pursuant to a qualified domestic relations order as defined by the Code or Title I of the Employee Retirement Income Security Act, or the rules thereunder. Any attempted assignment of an Option in violation of this Paragraph 9 shall be null and void. 10. Adjustments. (a) The existence of outstanding Options shall not affect in any manner the right or power of the Company or its stockholders to make or authorize any or all adjustments, recapitalization, reorganizations or other changes in the capital stock of the Company or its business or any merger or consolidation of the Company, or any issue of bonds, debentures, preferred or prior preference stock (whether or not such issue is prior to, on a parity with or junior to the Common Stock) or the dissolution or liquidation of the Company, or any sale or transfer of all or any part of its assets or business, or any other corporate act or proceeding of any kind, whether or not of a character similar to that of the acts or proceedings enumerated above. (b) In the event of any subdivision or consolidation of outstanding shares of Common Stock or declaration of a dividend payable in shares of Common Stock or capital reorganization or reclassification or other transaction involving an increase or reduction in the number of outstanding shares of Common Stock, the Board of Directors may adjust proportionally (i) the number of shares of Common Stock reserved under these Options; and (ii) the exercise price of such Options. In the event of any consolidation or merger of the Company with another corporation or entity or the adoption by the Company of a plan of exchange affecting the Common Stock or any distribution to holders of Common Stock of securities or property (other than normal cash dividends or dividends payable in Common Stock), the Board of Directors shall make such adjustments or other provisions as it may deem equitable, including adjustments to avoid fractional shares, to give proper effect to such event. In the event of a corporate merger, consolidation, acquisition of property or stock, separation, reorganization or liquidation, the Board of Directors shall be authorized to issue or assume stock options, regardless of whether in a transaction to which Section 424(a) of the Code applies, by means of substitution of new options for previously issued options or an assumption of previously issued options, or to make provision for the acceleration of the exercisability of, or lapse of restrictions with respect to, the termination of unexercised options in connection with such transaction. (c) An Option shall become fully exercisable upon a Change in Control (as hereinafter defined) of the Company. For purposes of this Plan, a "Change of Control" shall be conclusively deemed to have occurred if (and only if) any of the following events shall have occurred: (a) there shall have occurred an event required to be reported in response to Item 6(e) of Schedule 14A of Regulation 14A (or in response to any similar item on any similar schedule or form) promulgated under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), whether or not the Company is then subject to such reporting requirement; (b) any "person" (as such term is used in Sections 13(d) and 14(d) of the Exchange Act) shall have become the "beneficial owner" (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the Company representing 20% or more of the combined voting power of the Company's then outstanding voting 73 securities without prior approval of at least two-thirds of the members of the Board of Directors in office immediately prior to such person's attaining such percentage interest; (c) the Company is a party to a merger, consolidation, sale of assets or other reorganization, or a proxy contest, as a consequence of which members of the Board of Directors in office immediately prior to such transaction or event constitute less than a majority of the Board of Directors thereafter or (d) during any period of two consecutiveyears, individuals who at the beginning of such period constituted the Board of Directors (including for this purpose any new director whose election or nomination for election by the Company's stockholders was approved by a vote of at least two-thirds of the directors then still in office who were directors at the beginning of such period) cease for any reason to constitute at least a majority of the Board of Directors. 11. Purchase for Investment. Unless the Options and shares of Common Stock covered by this Plan have been registered under the Securities Act of 1933, as amended, each person exercising an Option under this Plan may be required by the Company to give a representation in writing in form and substance satisfactory to the Company to the effect that he is acquiring such shares for his own account for investment and not with a view to, or for sale in connection with, the distribution of such shares or any part thereof. 12. Taxes. The Company may make such provisions as it may deem appropriate for the withholding of any taxes that it determines is required in connection with any Options granted to any Optionee hereunder. 13. Amendments or Termination. The Board of Directors of the Company may amend, alter or discontinue this Plan, except that (a) no amendment or alteration that would impair the rights of any Optionee under any Option that he has been granted shall be made without his consent and (b) no amendment or alteration shall be effective prior to approval by the Company's stockholders to the extent such approval is then required. 14. Government Regulations. This Plan, and the granting and exercise of Options hereunder, and the obligation of the Company to sell and deliver shares of Common Stock under such Options, shall be subject to all applicable laws, rules and regulations, and to such approvals on the part of any governmental agencies or national securities exchanges or transaction reporting systems as may be required. 15. Governing Law. This Plan and all determinations made and actions taken pursuant hereto, to the extent not otherwise governed by mandatory provisions of the Code or the securities laws of the United States, shall be governed by and construed in accordance with the laws of the State of Delaware. 16. Effective Date of Plan. This amended and restated Plan shall be effective as of the date (the "Effective Date") it is approved by the Board of Directors of the Company. Notwithstanding the foregoing, the adoption of this amended and restated Plan is expressly conditioned upon the approval by the holders of a majority of shares of Common Stock present, or represented, and entitled to vote at a meeting of the Company's stockholders held on or before December 31, 1998. If the stockholders of the Company should fail so to approve this amended and restated Plan prior to such date, this amended and restated Plan shall revert to the provisions of the prior plan and all grants of options hereunder in excess of The Plan's limitations shall be null and void. 17. Miscellaneous. The granting of any Option shall not impose upon the Company, the Board of Directors of the Company or any other directors of the Company any obligation to nominate any Optionee for election as a director and the right of the stockholders of the Company to remove any person as a director of the Company shall not be diminished or affected by reason of the fact that an Option has been granted to such person. 74
