Second Amendment to Rights Agreement

Effective March 16, 1999, the Registrant entered into a Rights Agreement with Mellon Investor Services LLC (formerly known as ChaseMellon Shareholder Services, L.L.C.), as Rights Agent (the “Rights Agent”), which was subsequently amended by the First Amendment to Rights Agreement dated as of April 3, 2002 (as so amended, the “Rights Agreement”). In connection with the Merger Agreement described above, effective October 13, 2005, the Registrant entered into the Second Amendment to the Rights Agreement (the “Second Amendment”). As more fully set forth in the Second Amendment, the Second Amendment, among other things:

•

renders the provisions of the Rights Agreement inapplicable to the Merger by exempting Parent and Merger Sub from the definition of “Acquiring Person” and providing that a “Distribution Date” shall not be deemed to have occurred due to the execution and delivery of the Merger Agreement and the consummation of the Merger; and

•

provides for the termination of the Rights Agreement (except for the rights, obligations and liabilities of the Registrant and the Rights Agent set forth in Section 18 of the Rights Agreement) immediately prior to the effective time of the Merger.

A copy of the Second Amendment has been filed with the SEC as an Exhibit to the Registrant’s Amendment No. 2 to the Registration Statement on Form 8-A/A, dated October 17, 2005, and is incorporated by reference as though fully set forth herein. The foregoing description of the Second Amendment is qualified in its entirety by reference to the full text of the Second Amendment.

Discretionary Performance Bonus Program

In 1999, the Registrant’s Board of Directors established the Vintage Petroleum, Inc. Discretionary Performance Bonus Program (as amended, the “DPB Program”). The purpose of the DPB Program is to enhance stockholder value by providing eligible employees of the Registrant, including executive officers, with an added incentive to achieve specific annual targets and goals. The DPB Program also allows the Registrant to remain competitive with its peers in attracting and retaining qualified personnel. The targets and goals are approved by the Board of Directors. During 2005, the Registrant’s executive officers and all other U.S. employees are eligible for cash incentive awards under the DPB Program. Each executive officer of the Company is eligible to earn an individual award expressed as a percentage of base salary paid during the DPB Program year. Executive officer cash incentive award opportunities vary by level of responsibility. There is no minimum incentive award. The maximum percentage of base

salary payable as a cash incentive award is 75%, 105% or 150%, depending on the executive officer’s position. Awards may be granted if specified Registrant financial and operating performance targets and individual performance levels are achieved and the Board of Directors determines to grant such bonuses.

Effective October 13, 2005, in light of the Merger and the Registrant’s performance through September 30, 2005, and projected performance for the fourth quarter of 2005, the Board of Directors, upon the recommendation of its Compensation Committee, granted bonuses for 2005 under the DPB Program to eligible U.S. employees, including executive officers, of the Registrant. These bonuses are payable to those eligible U.S. employees who remain with the Registrant until the earlier of the closing of the Merger or February 28, 2006. The following table sets forth the bonuses approved for 2005 under the DPB Program for the “named executive officers” of the Registrant who (a) appeared in the Company’s proxy statement for its 2005 Annual Meeting of Stockholders, except for William E. Dozier who is no longer employed by the Registrant, or (b) are expected to appear in the Company’s proxy statement for its 2006 Annual Meeting of Stockholders, if any:


	Year	Bonus
Charles C. Stephenson, Jr. Chairman, President and Chief Executive Officer	2005	$	461,250
William C. Barnes Executive Vice President and Chief Financial Officer	2005	$	227,448
William L. Abernathy Executive Vice President and Chief Operating Officer	2005	$	220,273
Larry W. Sheppard Senior Vice President – New Ventures	2005	$	121,275
J. Chris Jacobsen Vice President – U.S. Operations	2005	$	117,150

Completion Bonuses

Effective October 13, 2005, the Board of Directors, upon the recommendation of its Compensation Committee, established a completion bonus program for the Registrant’s Tulsa office employees, including certain executive officers, and expatriate employees of the Registrant who remain with the Registrant through the closing of the Merger. The completion bonus is payable at closing of the Merger, and, if the Merger does not occur, no completion bonuses will be paid. Messrs. Stephenson, Barnes and Abernathy are not eligible to receive completion bonuses. The only “named executive officers” eligible to receive a completion bonus are Messrs. Sheppard and Jacobsen. The estimated completion bonus amount is $281,500 for Mr. Sheppard and $123,000 for Mr. Jacobsen.

Performance-Based Cash Bonus Program for Chief Executive Officer

On December 22, 2004, the Compensation Committee of the Board of Directors of the Registrant established a performance-based cash bonus program for Mr. Stephenson (the “CEO Bonus Program”). The purpose of the CEO Bonus Program is to provide Mr. Stephenson with added incentive to enhance stockholder value by achieving certain specific performance goals.

The CEO Bonus Program establishes a base cash bonus amount of $1.2 million (the “Base Amount”). Under the CEO Bonus Program, Mr. Stephenson has the ability to earn a cash bonus in the amount of 0% to 200% of the Base Amount (or $0 to $2.4 million), based upon the Registrant’s “total stockholder return” as compared to the “total stockholder return” of each company in a peer group of companies selected by the Compensation Committee during a performance period commencing on January 1, 2004, and ending on December 31, 2006 (the “Performance Period”). The amount of the cash bonus earned, if any, will depend on the “Registrant’s rank” among the peer group of companies.

In the event of Mr. Stephenson’s death, “disability” or termination of employment by the Registrant without “cause” prior to the date of determination of whether he is entitled to a bonus, he will receive a cash bonus, if any, in the amount that he would be entitled to as of the date of occurrence of such event under the performance criteria described above if the Performance Period ended as of the date of the occurrence of such event. In the event of a “change in control” of the Registrant (as defined in the Registrant’s 1990 Stock Plan, as amended) prior to the date of determination of whether he is entitled to a bonus, Mr. Stephenson will receive the Base Amount. In the event of Mr. Stephenson’s voluntary termination of employment prior to the date of determination of whether he is entitled to a bonus, he will receive no cash bonus.

Effective October 13, 2005, the Compensation Committee of the Board of Directors, modified the Bonus Program to provide that, in the event the Merger occurs, Mr. Stephenson will be paid 200% of the Base Amount or $2.4 million. This amount is payable at the closing of the Merger.

Performance-Based Restricted Stock Rights

From time to time prior to October 1, 2005, the executive officers of the Registrant have been granted performance-based restricted stock rights under the Registrant’s 1990 Stock Plan, as amended. Under these rights, the executive officer has the ability to earn a number of shares of the Registrant’s common stock in the amount of 0% to 200% of a base number of shares (“Base Number”) based upon the Registrant’s total stockholder return as compared to the total stockholder return of each company in a peer group of companies selected by the Compensation Committee of the Board of Directors of the Registrant during a three-year performance period. The number of shares earned depends on the Registrant’s rank among the peer group of companies. In the event of a “change in control” of the Registrant (as defined in the Registrant’s 1990 Stock Plan, as amended), the executive officer will receive the Base Number.

Effective October 13, 2005, the Compensation Committee of the Board of Directors modified such performance-based restricted stock rights to provide that, in the event the Merger occurs, the executive officer will receive 200% of the Base Number.

Gross-Up Payments for Internal Revenue Code Section 4999 Excise Taxes

Effective October 13, 2005, the Registrant has agreed to make payments to save each of its Tulsa-based employees, including any “named executive officer,” harmless from the effect of any excise tax imposed by Section 4999 of the Internal Revenue Code on any excess parachute payment made to such employee in connection with the Merger. In general, Section 4999 imposes an excise tax on the recipient of any excess parachute payment equal to 20% of that payment. A parachute payment is any payment in the nature of compensation to a disqualified individual (as defined under Section 280G of the Internal Revenue Code) if such payment is (a) contingent on a change in control and (b) the aggregate present value of the payments in the nature of compensation to such individual which are contingent on such change equals or exceeds an amount equal to three times the “base amount” (average compensation over the previous five-year period of employment). The term “contingent on a change in control” means not only that a payment would not have been made but for the change in control (a condition precedent), it also means a payment for which the timing of such payment is accelerated as a result of the change in control. The Registrant has also agreed to make payments to save each of its expatriate employees harmless from the effect of such excise tax if applicable to them.
