NOW THEREFORE, for and in consideration of the foregoing and the agreements contained herein, the Company and Executive do hereby agree as follows:

“1. EMPLOYMENT AND TERM. The Executive’s December 2, 2002 Employment Agreement (the ‘2002 Employment Agreement’) is hereby superseded by this Agreement, and effective as of the Effective Date, Executive shall have no further rights and the Company shall have no further liabilities under the 2002 Employment Agreement.

This Agreement will be automatically extended for an additional year on the first anniversary date hereof and every subsequent anniversary date unless terminated by either the Company or the Executive by the giving of written notice to the other party no later than three (3) months prior to the first anniversary date hereof or any such subsequent anniversary date, as the case may be. Effective as of the Execution Date, the Executive shall no longer be President or Treasurer of the Company but shall retain the position of CEO. The entire period that Executive is employed under this Agreement shall be referred to in this Agreement as the ‘Employment Term’.”

Section 4(C) of the Original Agreement is hereby amended by deleting the words “and President” contained therein.

(e) Section 6(A)(ii) of the Original Agreement is hereby amended by replacing the sentence contained therein with “The Company’s ‘Business’ means the business of oil and gas exploration or production conducted in the Gulf of Mexico and such other and further business of the Company as the same may exist from time to time.” Section 6(A)(iii) of the Original Agreement containing the definition of “Compete” is hereby amended by replacing the last sentence thereof with “W&T Offshore, LLC shall not be considered to Compete with the Company’s Business.” Section 6(F) of the Original Agreement is hereby amended by deleting the phase “and for a period of two (2) years thereafter (such period, the ‘Non-Compete Period’)” in the second and third lines thereof. The remedy provisions of Section 6(G) of the Original Agreement are hereby deleted and said Section 6(G) shall hereafter recite “Intentionally Deleted”.

(i) Section 18 is added to the Original Agreement as follows:

“18. AIRCRAFT. Since the Effective Date, in an effort to provide for the personal safety of the Executive and to facilitate efficient travel, the Company has authorized the use of Company supplied aircraft by the Executive. Accordingly, during the Employment Term, the Executive shall have the right to use Company fractional ownership or chartered aircraft (excluding private aircraft owned by the Executive) for any reason, whether personal or business related. In addition, private aircraft owned by the Executive may be chartered by the Company for only business purposes of the Company, not to exceed 25 hours of flight time in any calendar year (pro-rated for the period from the Execution Date until the end of year 2008), unless the Audit Committee has authorized use in excess of 25 hours in any calendar year; provided, however, the costs to the Company to charter the private aircraft owned by the Executive for any trip shall never exceed the cost to charter an aircraft that meets the needs for such trip (taking into account required seating capacity, operational requirements and flight duration) as determined by the Chief Financial Officer of the Company (based on the rates of at least two third-party operators, which may include Flight Options and EJM as acceptable sources). The Chief Financial Officer of the Company shall provide the Audit Committee a quarterly accounting of the use by the Executive of

both Company fractional ownership or chartered aircraft and the private aircraft owned by the Executive. The tax implications to the Executive and the required SEC disclosures shall be determined by the Chief Financial Officer of the Company in accordance with applicable law and regulations.”

IN WITNESS WHEREOF, the parties hereto have executed this Amendment effective the 14th day of October, 2008 (the “Execution Date”).
