         Plan.

                  3.       VACATION AND EMPLOYEE BENEFITS.

                           Executive shall be entitled to fifteen (15) days of
         vacation and five (5) personal days per year, to be taken in such
         amounts and at such times as shall be mutually convenient for Executive
         and the Company. Any vacation days exceeding five (5) days not taken by

         person or committee administering such plan.

4.       BUSINESS EXPENSES.

                           During his Employment, the Executive shall be
         authorized to incur necessary and reasonable travel, entertainment and
         other business expenses in connection with his duties hereunder. The
         Company shall reimburse the Executive for such expenses upon
         presentation of an itemized account and appropriate supporting
         documentation, all in accordance with the Company's generally
         applicable policies.

                  5.       TERMINATION OF EMPLOYMENT.

                           (a) TERMINATION OF EMPLOYMENT. The Company may
         terminate the Executive's Employment at any time and for any reason (or
         no reason), and with or without Cause, by giving the Executive ten
         day's notice in writing. The Executive may terminate his Employment by
         giving the Company ten days' advance notice in writing. The Executive's
         Employment shall terminate automatically in the event of his death. The
         termination of the Executive's Employment shall not limit or otherwise
         affect his obligations under Section 7.

                           (b) EMPLOYMENT AT WILL. The Executive's Employment
         with the Company shall be "at will," meaning that either the Executive
         or the Company shall be entitled to terminate the Executive's
         Employment at any time and for any reason, with or without Cause. Any
         contrary representations that may have been made to the Executive shall
         be superseded by this Agreement. This Agreement shall constitute the
         full and complete agreement between the Executive and the Company on
         the "at will" nature of the Executive's Employment, which may only be
         changed in an express written agreement signed by the Executive and a
         duly authorized officer of the Company.

                           (c) RIGHTS UPON TERMINATION. Except as expressly
         provided in Section 6, upon the termination of the Executive's
         Employment, the Executive shall only be entitled to the compensation,
         benefits and expense reimbursements that the Executive has earned or
         accrued under this Agreement before the effective date of the
         termination. Termination payments pursuant to Section 6 shall fully
         discharge all responsibilities of Company to Executive except for the
         Company's responsibilities listed in Sections 2, 3, 4, 5, 8, 9, 10 and
         Exhibits B, C and D herein.

         of Executive.

                           (ii) Executive acknowledges that he has and will have

         Company as of Executive's termination, business of the same or of a
         similar nature to the business of the Company with such client, if such
         business is expected to directly compete with the Company;

                           (ii) solicit from any known potential client of the
         Company business of the same or of a similar nature to that which has

                           (iii) solicit the employment or services of, or hire,
         any person who was known to be employed by the Company upon termination

                                    EXHIBIT A
                                 OTHER INTERESTS

         In accordance with Section 1 (b) of the Employment Agreement dated as
of March __, 2005, (the "Agreement"), the Company hereby consents and approves
of the following business interests conducted by Executive that are not directly
related to Company matters:

Executive serves the board of directors of Boots and Coots Group, Inc., a
publicly owned well service company that is not in direct or indirect
competition with the Company. The Company recognizes that it may benefit from
such activities, in that they broaden Executive's corporate governance
experience and extends Executive's exposure to industry. Executive currently
devotes a minimal amount of time per month on such activities and does not
believe that such service materially and adversely impacts his ability to
perform under the Agreement.

Executive is a partner with Tatum CFO Partners, a provider of contract CFO's and
other C level executives to industry and Tatum provides ongoing services to the
Company pursuant to a Services Agreement. Executive was introduced to the
Company through Tatum CFO Partners and intends to maintain that relationship,
however, Executive has not in the past, during his Employment with the Company,
and does not intend during the term of the Agreement to expend any material
business time or effort to such relationship, including the provision of
services to other companies. The Tatum CFO Partner services are valuable to the
Company by providing immediate resources in the areas of finance, accounting,
information services, management issues, human resources and other issues.

Executive currently owns direct minor oil and gas interests through a family
entity, none of which are directly or indirectly competitive with the Company's
interests. Executive agrees to advise the Company of any contemplated
investments that might be construed to be competitive with Company's interests,
prior to making such additional investments. Such ownership does not utilize a
material amount of Executive's time and none of Executive's business time or
efforts.
