4.1    ESTABLISHMENT OF PERFORMANCE OBJECTIVES AND INCENTIVE OPPORTUNITY. Within 90 days of the commencement of each Plan Year (or such later time as may be permitted for performance-based compensation under Section 162(m)), the Committee shall establish written performance objectives and a cash

incentive opportunity for each Participant chosen to receive an incentive for such Plan Year. At the time of setting the performance objectives, the Committee shall specify the formula to be used in calculating each of the criteria on which an incentive is based and their relative weights. The incentive opportunity shall be expressed as an amount of cash or percentage of salary. The Committee may also specify a minimum acceptable level of achievement of the relevant performance objectives, as well as one or more additional levels of achievement, and a formula to determine the percentage of the incentive opportunity earned by the employee upon attainment of each such level of achievement. The performance objectives and incentive opportunity relating to any particular incentive need not be the same as those relating to any other incentive, whether made at the same or a different time. The Committee may delegate to the Chief Executive Officer of the Company the establishment and measurement of such performance objectives for Participants who are not Covered Employees.

4.2    PERFORMANCE OBJECTIVES CRITERIA.

(a) Criteria.

5

(9) measures of selected operations activities such as number of wells drilled or number of miles of pipe installed;        

10) satisfactory completion of a major project or organizational initiative with specific criteria set in advance by the Committee defining “satisfactory”;

(11) debt ratios or other measures of credit quality or liquidity;

(12) strategic asset sales or acquisitions in compliance with specific criteria set in advance by the Committee.

(c)    Per Share Adjustments. Performance objectives set on a per share basis such as earnings or cash flow per share shall be appropriately adjusted to reflect changes in outstanding shares resulting from stock dividends, splits or combinations or mergers, reorganizations or similar transactions.

(d)    Non-Covered Employees. The performance objectives for Participants who are not Covered Employees may be based on Section 162(m) Criteria or on criteria different from or supplemental to the Section 162(m) Criteria.

4.3    EARNING OF INCENTIVE, INDIVIDUAL MAXIMUM. Promptlyafter the date on which the necessary information for a particular Plan Year becomes available, the Committee shall determine the extent to which the incentive opportunity for such Plan Year has been earned through the achievement of the relevant performance objectives by each Participant who was granted an incentive for such Plan Year. At its discretion, the Committee may reduce a Participant’s earned incentive by up to 25%. The Committee shall certify in writing the earned incentives adjusted for any discretionary reductions. Notwithstanding the terms of any incentive, the maximum incentive under this Plan to any individual for any one Plan Year shall not exceed $2.5 million.

4.4PAYMENT OF INCENTIVES. Promptly after the Committee has certified in writing that an incentive has been earned and any discretionary reductions, such incentives shall be paid in cash in a lump sum, provided, that any amounts, the payment of which has been deferred under the Energen Corporation 1997 Deferred Compensation Plan or any successor plan, shall be credited to the Participant’s account in accordance with the terms of that plan.

4.5TERMINATION OF EMPLOYMENT – COMPLETED PLAN YEAR. If Participant’s employment is terminated for any reason (including death, disability or retirement) other than Cause after the end of a Plan Year but before payment of incentives for such Plan Year, the Participant shall remain entitled to payment of incentives, if any, earned for such Plan Year. A Participant whose employment is terminated for Cause after the end of a Plan Year but before payment of incentives for such Plan Year shall not receive payment of any incentive for the completed Plan Year.

4.6TERMINATION OF EMPLOYMENT – PARTIAL PLAN YEAR – NO CHANGE IN CONTROL. If prior to the last day of a Plan Year during which a Change in Control does not occur (a “Routine Plan Year”), a Participant’s employment terminates as a result of the Participant's death, disability, or Retirement, such Participant shall receive an incentive equal to the amount that the Participant would have received as an incentive if such Participant had remained an employee through the end of the Plan Year multiplied by a fraction, the numerator of which is the number of days that elapsed during the Plan Year in which the termination occurs prior to and including the date of the Participant’s termination of employment and the denominator of which is the number of days in the full Plan Year (a "pro rata incentive"). If a Participant's employment terminates for any other reason during a Routine Plan Year, then no incentive shall be payable to the Participant for such Plan Year, provided, that at its discretion, the Committee may determine to pay such Participant (other than a Participant terminated for cause) up to a pro rata incentive.

7

4.7TERMINATION OF EMPLOYMENT – PARTIAL PLAN YEAR – WITH CHANGE IN CONTROL. If prior to the last day of a Plan Year during which a Change in Control occurs (a “Change in Control Plan Year”),

(i) a Participant’s employment terminates as a result of the Participant's death, disability, or Retirement, or

(ii) after the occurrence of the Change in Control, the Participant’s employment is otherwise involuntarily terminated other than for Cause, including a termination for good reason entitling the Participant to severance compensation under a written change in control severance compensation agreement between the Company or a Subsidary and the Participant;

such Participant shall receive an incentive equal to the Participant’s target incentive for the Plan Year multiplied by a fraction, the numerator of which is the number of days that elapsed during the Plan Year in which the termination occurs prior to and including the date of the Participant’s termination of employment and the denominator of which is the number of days in the full Plan Year (a "pro rata incentive"). If a Participant's employment terminates for any other reason during a Change in Control Plan Year, then no incentive shall be payable to the Participant for such Plan Year, provided, that at its discretion, the Committee may determine to pay such Participant (other than a Participant terminated for cause) up to a pro rata incentive.
