EX-10.7 4 0004.txt OFFICER SEVERANCE AND PUT RIGHT AGRMNT (STALEY) EXHIBIT 10.7 OFFICER SEVERANCE AND PUT RIGHT AGREEMENT This Officer Severance and Put Right Agreement ("Agreement") is made and entered into as of this 1st day of August, 2000, by and between Pure Resources, Inc., a Delaware corporation (the "Company"), and George G. Staley, an individual currently residing in Midland, Texas ("Officer"). RECITALS -------- The Board of Directors of the Company (the "Board") has determined that it is in the best interest of the Company to assure that the Company will have the continued dedication of Officer, notwithstanding the consummation as of 11:58 p.m. Central time on May 25, 2000 (the "Effective Time") of the transactions contemplated by that certain Agreement and Plan of Merger (the "Merger Agreement"), dated December 13, 1999, among Union Oil Company of California, the Company, TRH, Inc. and Titan Exploration, Inc. and the possibility, threat or occurrence of a Company Change of Control or a Unocal Change of Control (each as defined below). The Board believes it is imperative to diminish the inevitable distraction of Officer by virtue of the personal uncertainties and risks created by a pending or threatened Company Change of Control or Unocal Change of Control, to encourage Officer's full attention and dedication to the Company currently and in the event of any threatened or pending Company Change of Control or Unocal Change of Control, and to provide Officer with compensation and benefit arrangements upon a Company Change of Control or Unocal Change of Control which ensures that such compensation and benefits are competitive with other corporations. AGREEMENT --------- Now, therefore, in consideration of Officer's continued employment by the Company or an affiliate of the Company, as well as the promises, covenants and obligations contained herein, the Company and Officer agree as follows: 1. Severance and Other Benefits. ---------------------------- (a) Severance Payment. Upon the occurrence of a Termination Event (as ----------------- defined in Section 3): (i) within 30 days following such Termination Event, upon Officer's execution of a General Release materially in the form attached hereto as Exhibit A (the "General Release"), the Company or its successor (or an affiliate of the Company or any successor thereto) shall pay Officer an amount equal to Officer's Annual Base Salary (as defined in Section 3) multiplied by 2.0, payable as a lump sum cash payment; (ii) if Officer was participating in a life insurance and/or disability benefit plan maintained by an Employer as of his or her Termination Date, such coverage will be continued at the same cost, if any, charged to similarly situated active employees under such plans for a period of eighteen months following the Termination Date or, if earlier, the date as of which Officer obtains other employment. Officer shall immediately notify the Company upon obtaining other employment; (iii) if Officer was participating in a hospital, surgical, medical or dental benefit plan maintained by an Employer as of his or her Termination Date and if Officer elects to continue such coverage under the Consolidated Omnibus Budget Reconciliation Act of 1985 ("COBRA"), Officer will be reimbursed the premiums paid to continue such coverage under COBRA until the date as of which Officer obtains other employment. Officer shall immediately notify the Company upon obtaining other employment; (iv) all restricted stock, options or other rights with respect to equity interests in the Company and/or its affiliates granted to Officer on or before such Termination Date shall immediately vest as of the Termination Date; and (v) the Company or any successor thereto (or an affiliate of the Company or any successor thereto) shall take all such action as may be necessary or appropriate to amend any option to purchase the Company's common stock held by Officer to provide that such option will not terminate as a result of or in connection with Officer's termination of employment with the Company or any successor thereto (or an affiliate of the Company or any successor thereto), but may continue to be exercised following such termination of employment until the date on which such options otherwise would expire. 2. Put Right. --------- (a) Upon the occurrence of a Put Event, Officer shall have the option (the "Put Option"), exercisable at any time before the 90th day after the Put Event, to sell to the Company all or part (in each case, subject to Section 2(e)) of his Continuing Company Shares at a price calculated in accordance with the provisions of Section 2(d); provided, however, that if Officer fails to exercise such Put Option (other than with respect to a Put Event described in clause (iii) of the definition of Put Event) or exercises such Put Option for less than all of his Continuing Company Shares, Officer shall not have the right to require the Company to purchase any shares upon the occurrence of any future Put Event. If Officer exercises the Put Option within the specified period by giving notice (the "Put Notice") to the Company of his or her election to do so (the date such notice is given is the "Put Date"), the Company shall be required to purchase all (but, subject to Section 2(e), not less than all) of the Continuing Company Shares specified by Officer in the Put Notice (which may include Continuing Company Shares owned by Officer as of the Put Date and/or Continuing Company Shares to be acquired by the Officer pursuant to option exercises after the Put Date but on or before the Put Closing), such purchase to be effected in the manner, upon the terms and for the consideration set forth hereafter. In the event of Officer's death, Officer's heirs or beneficiaries shall have the right to exercise the Put Option described above. (b) The consummation of any purchase required under this Section 2 shall be held at a "Put Closing", and the time and date upon which the Put Closing shall take place shall constitute the "Put Closing Date". The Put Closing shall be held at the principal office of the Company on the date designated by Officer in the Put Notice or on such other date as shall be mutually agreed upon in writing by the Company and Officer; provided, however, that the Put Closing Date shall not be more than 30 days (or a period of such additional length as reasonably necessary to complete the additional valuations contemplated in the definition of Net Asset Value) nor less than three days after the delivery of the Put Notice. In addition to providing the Put Closing Date, the Put Notice shall set forth the number of shares to be purchased by the Company and the Purchase Price (as defined below). (c) At the Put Closing, Officer shall present to the Company all share certificates or option agreements for Continuing Company Shares required to be purchased, duly endorsed in blank and in proper form for transfer, or with separate stock powers attached, duly endorsed in blank and in proper form for transfer, free and clear of any encumbrances. At the Put Closing, the Company, upon receipt of a conforming tender from Officer, shall tender full payment of the Purchase Price in immediately available funds by -2- confirmed wire transfer to a bank account to be designated by Officer (such designation to occur no later than the second business day prior to the Put Closing Date). (d) The total purchase price (the "Purchase Price") for all the shares of Common Stock to be purchased pursuant to this Section 2 shall be equal to the number of shares of Continuing Company Shares held by, or issuable to, Officer which are subject to the Put Closing multiplied by the Price Per Share. The "Price Per Share" shall be equal to the Net Asset Value divided by the Fully- Diluted Outstanding Share Amount, each determined as of the Put Date. (e) If the Company is unable to consummate any desired purchase of Continuing Company Shares pursuant to the terms of this Agreement because of limitations contained in the Delaware Business Corporation Act (or a successor statute thereof) or other applicable law, the Company agrees to use its best efforts to take all such action as may be available to place the Company in a position to carry out any required purchase under this Agreement. If the Company, after the taking of any action by it as contemplated in the immediately preceding sentence, is unable to consummate the purchase of all the shares of Officer's Continuing Company Shares as required, the Company shall purchase at the applicable price all shares of Continuing Company Shares that the Company shall then be authorized to purchase under the provisions of applicable law, and shall purchase the remainder of such shares as soon thereafter as possible at the applicable price, plus accrued interest on such purchase price at the floating prime borrowing rate specified by the lead bank on the Company's principal revolving credit facility or, if there is no such bank, a comparable prime rate selected in good faith by the Board of Directors. 3. Definitions. ----------- (a) "Annual Base Salary," as determined on the Termination Date shall be equal to the sum of (i) the annual base salary payable to Officer by the Company or any successor thereto (or any affiliate of the Company or a successor thereto) as of the Termination Date plus (ii) an amount equal to the greater of (A) the bonus earned by Officer for the calendar year immediately preceding the Termination Date or (B) the average annual bonus earned by Officer during the three calendar years immediately preceding the Termination Date.
