AGREEMENT THIS AGREEMENT is made and entered into this 16th day of July, 1996, but effective on July 31, 1996, by and between F.H. Smith (Employee) and Patina Oil & Gas Corporation ("Patina or the Company"). RECITALS 1. Employee is employed by Patina as a Vice President of Operations. 2. Employee's employment with Patina commenced on May 2, 1996 as a result of the closing of the transactions contemplated by an amended and restated Agreement and Plan of Merger dated as of January 16, 1996 and amended and restated as of March 20, 1996 by and among Snyder Oil Corporation, Patina Oil & Gas Corporation, Patina Merger Corporation and Gerrity Oil & Gas Corporation (the "Merger"). 3. As a result of the Merger, Patina determined that certain positions held by former Snyder Oil Corporation employees and former Gerrity Oil & Gas employees were no longer necessary and certain employees were laid off as a result of the Merger. Employee's position initially was not one identified as being no longer necessary as a consequence of the Merger. 4. While Employee's position was not initially identified as one to be eliminated as a result of the Merger, it has now been identified as being duplicative and no longer necessary for the ongoing operations of Patina. 5. As a result, Employee and Patina have agreed to enter into this Agreement pursuant to which Employee is being laid off as a direct consequence of the Merger. AGREEMENT In consideration of a payment by Patina to Employee of the amounts set forth herein, and in further consideration of the mutual covenants, conditions and stipulations set forth in this Agreement, Employee and Patina agree, effective as provided in paragraph 7 as follows: 1. Employee's employment with Patina will terminate effective 5:00 p.m., Mountain Daylight Time, July 31, 1996. On July 31, 1996, Employee will be paid his regular salary for July 1996, subject to normal and standard deductions for FICA, Medicare, tax, state and federal taxes, all as applicable. In addition, Employee will be paid the sum of $75,000 (subject to applicable withholdings and deductions, if any) as a severance allowance. In addition, as of July 31, 1996, Employee will have accrued 20.75 days of vacation for which he will be paid. Employee may purchase from Patina, the Company vehicle he currently is utilizing for Company business if Patina and Employee agree on a purchase price on or before July 25, 1996. If Employee purchases the vehicle, the purchase price for the vehicle will be deducted from Employee's severance allowance and accrued vacation payment. If Employee purchases the vehicle, clear title to the vehicle will be delivered to Employee on July 31, 1996. 2. In consideration of the foregoing, Employee hereby knowingly and voluntarily, fully and finally releases, acquits, and forever discharges Patina, Gerrity Oil & Gas Corporation and SOCO Wattenberg Corporation and any affiliates and their past and present officers, directors, (in their capacity as officers and directors), stockholders, partners, trustees, beneficiaries, managers, employees, attorneys, agents, successors or assigns (collectively, the "Company and Related Release Parties"), from any and all claims, charges, complaints, liens, demands, causes of action, obligations, damages and liabilities, whether known or unknown, that he had, now has, or may after claim to have against the Company and Related Release Parties arising out of or relating in any way to Employee's relationship with Patina and/or its subsidiaries as an officer, director, employee, or in any other capacity, except those arising out of this Agreement and Rights to Indemnification under the Patina Certificate of Incorporation, By-Laws and Delaware law and directors and officers insurance as currently in effect. This Release expressly extends to, without limiting the generality of the foregoing, any claims arising under Title VII of the Civil Rights Act of 1964 as amended, Age Discrimination and Employment Act, as amended, the United States Constitution, any State Constitutions and any other federal, state or local statute, regulation or ordinance governing the employment relationship. 5.
