The Committee’s determinations under the Plan (including without limitation determinations of which Employees, if any, are to receive Awards, the form, amount and timing of such Awards, the terms and provisions of such Awards and the agreements evidencing same) may be made by the Committee selectively among Employees who receive, or are eligible to receive, Awards under the Plan.

ARTICLE 5

5.1     Performance Goals Establishment. Performance Goals shall be established by the Committee for each Performance Period. The Performance Goals may be identical for all Participants or, at the discretion of the Committee, may be different to reflect more appropriate measures of individual performance.

5.2     Awards. Awards shall be made annually in accordance with actual performance compared to the Performance Goals established by the Committee for the Performance Period and may be adjusted by the Committee in its sole discretion.

5.3     Performance Goals. Performance Goals may include alternative and multiple Performance Goals and may be based on one or more business and/or financial criteria. In establishing the Performance Goals for the Performance Period, the Committee in its discretion may include one or any combination of the following criteria in either absolute or relative terms (as compared to an external benchmark or performance of a designated peer group of companies), for either the Company or any of its Subsidiary organizations:

5

For the Performance Goals listed above, the Committee may designate whether a particular Performance Goal is to be measured on a pre-tax basis or post-tax basis. In addition, certain Performance Goals may be stated in reference to a production volume of measurement such as in per cubic feet equivalents (e.g., per Mcfe, MMcfe or Bcfe). Further, the Committee may select any one or more of the Performance Goals applicable to a Participant, and Performance Goals may differ for one Participant to the next.

5.4     Adjustments for Extraordinary Items. The Committee shall be authorized to make adjustments in the method of calculating attainment of Performance Goals in recognition of: (i) extraordinary or non-recurring items; (ii) changes in tax laws; (iii) changes in generally accepted accounting principles or changes in accounting policies; (iv) changes related to restructured or discontinued operations; (v) restatement of prior period financial results; and (vi) any other unusual, non-recurring gain or loss that is separately identified and quantified in the Company’s financial statements. Notwithstanding the foregoing, the Committee may, at its sole discretion, reduce the performance results upon which Awards are based under the Plan to offset any unintended result(s) arising from events not anticipated when the Performance Goals were established.

The Company or any Subsidiary, as applicable, shall have the right to deduct from any payments to be made pursuant to the Plan the amount of any taxes required by Federal, state or local law to be withheld with respect to such payments.

ARTICLE 8

NO RIGHT TO CONTINUED EMPLOYMENT OR AWARDS

No Employee shall have any claim or right to be made an Award, and the making of an Award shall not be construed as giving a Participant the right to be retained in the employ of the Company or any of its Subsidiaries. Further, the Company and its Subsidiaries expressly reserve the right at any time to terminate the employment of any Participant free from any liability under the Plan; except that a Participant, who meets or exceeds the Performance Goals for the Performance Period and was actively employed for the full term of the Performance Period, will be eligible for an Award even though the Participant is not an active employee of the Company or any Subsidiary at the time the Committee makes Awards under the Plan so long as Participant was not terminated for Cause prior to the time the Committee makes Awards under the Plan. If Participant was employed for the full term of the Performance Period but was terminated for Cause prior to the time the Committee makes Awards under the Plan, the Participant will not be eligible to receive an Award under the Plan for that Performance Period.
