                                                                    EXHIBIT 10.1

                         EXECUTIVE EMPLOYMENT AGREEMENT

         THIS EMPLOYMENT AGREEMENT ("Agreement") is made and entered effective
as of the 1st day of July, 1999, by and between VENUS EXPLORATION, INC., a
company organized and existing under the laws of the State of Delaware
("Company"), and E. L. AMES, JR., an individual residing in San Antonio, Bexar
County, Texas ("Employee").

         FOR AND IN CONSIDERATION of the mutual covenants herein contained and
the mutual benefits to be gained by the performance thereof and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto hereby agree as follows:

         1. EMPLOYMENT, Company hereby employs Employee and Employee hereby
accepts employment with Company on the terms and conditions herein set forth. In
consideration of Employee's employment by Company, Employee agrees to the terms,
conditions and covenants of this Agreement.

         2. TERM OF EMPLOYMENT. Employment of Employee by Company shall be for a
term of two (2) years.

         3. DUTIES AND RESPONSIBILITIES. Employee shall serve as Chief Executive
Officer and, if elected by the Board of Directors of the Company, Chairman of
the Board of Directors of the Company.

                  3.01 EXTENT OF SERVICES. Employee shall devote his efforts to
         the advancement of the interests of the company's business, and he
         shall pursue no new business interests other than passive investments,
         without the prior written approval of the Company, which approval shall
         not be unreasonably withheld. Employee shall minimize the interference
         any such activities have on the conduct of the Company's business.

                  3.02 APPROVED OTHER BUSINESS INTERESTS. The Company
         understands and accepts the facts that the Employee owns certain
         interests in oil and gas properties in his own right and that the
         Employee may develop those interests and the surrounding Areas of
         Mutual Interest without offering same to, or in any way involving, the
         Company. However, Employee agrees that he will not acquire any new
         interests outside of such Areas of Mutual Interests and that all new
         oil and gas projects in which he is involved outside of such Areas of
         Mutual Interest will be considered a Company project.

         4. COMPENSATION AND BENEFITS. The compensation and other benefits
listed below as payable to or accruing to Employee shall constitute the full
consideration to be paid to Employee for all services to be rendered by Employee
to Company and all other agreements of Employee hereunder.

                  4.01 BASE SALARY. As compensation for all services of whatever
         type rendered by Employee in the performance of his duties under this
         Agreement and for all other agreements and undertakings of Employee
         hereunder, Company shall pay to Employee a base salary to be determined
         from time to time and approved by the Board of Directors; however, in
         no event will such salary be less than $190,000.00 per year without the
         written consent of Employee. Such salary shall be payable in equal
         regular installments in accordance with Company's customary


                                      -1-
   2

         payroll payment policy. It is specifically understood and agreed that a
         portion of Employee's annual base salary hereunder is attributable to
         Employee's agreement, pursuant to Section 8 hereof, to maintain the
         confidentiality of "Confidential Information" (as herein defined), both
         during and after the term of this Agreement, and that Employee's salary
         would be reduced significantly if Employee did not agree to be bound by
         the terms of Section 8. It is further understood and agreed that a
         portion of Employee's annual base salary is attributable to Employee's
         agreement, pursuant to Section 9 hereof, not to compete with Company
         either during or for a specified period of time after the expiration or
         termination of this Agreement and that Employee's annual salary would
         be reduced significantly if Employee did not agree to be bound by the
         terms of Section 9 hereof . Employee agrees that he is being fairly and
         reasonably compensated for the agreements undertaken by Employee
         pursuant to Sections 8 and 9 hereof.

                  4.02 BENEFITS. Employee shall be entitled to four weeks paid
         vacation each year, subject to the times for such vacation being
         mutually agreed upon by Employee and Company. Employee shall be
         entitled to participate in the Company benefit programs designed for
         Company employees with similar salaries, duties and responsibilities.

                  4.03 EXPENSES. Company shall pay or reimburse Employee for all
         reasonable and necessary expenses actually incurred or paid by Employee
         during the term of this Agreement in the performance of Employee's
         services under this Agreement, upon presentation of expense statements
         or vouchers or such other supporting documents as Company may
         reasonably require.

                  4.04 AUTOMOBILE. The Company shall provide Employee an
         automobile of class, style and age that are commensurate with the
         position he holds and the needs of Employee in that position.

         5. REPRESENTATIONS, WARRANTIES AND AGREEMENTS. Employee represents,
warrants and agrees that: (i) Employee is not currently bound by any employment
agreement, restriction or other obligation of any kind that would in any way
materially interfere with or be inconsistent with the services to be provided by
Employee to Company hereunder; and (ii) Employee is free to enter into this
Agreement and the services and work product provided by Employee to Company
hereunder will be original works of Employee.

         6. REGULATIONS AND POLICIES. Employee shall, during the term of this
Agreement, comply with all Company regulations and policies, including, without
limitation, security regulations.

         7. CONFIDENTIAL INFORMATION. The term "Confidential Information," as
used herein, shall mean and include any and all documents, knowledge, data or
information (in whatever medium) known, communicated, provided or made available
to Employee, whether before or after the execution of this Agreement, which are
marked with a confidentiality legend by Company or which Employee knows or
reasonably should know constitute trade secrets of Company or information
belonging to third parties to whom Company may have an obligation of
confidentiality; provided, however, that Confidential Information shall not
include any information or materials which are or become generally available to
the public other than as a result of any breach of the provisions of this
Agreement or any other agreement between Employee and Company (or their
respective successors, assigns or affiliates).

         8. CONFIDENTIALITY. Employee acknowledges and agrees that in his
employment by Company he occupies a position of trust and confidence and that
during the term of his employment


                                      -2-
   3

under this Agreement he will have access to and will become familiar with
Company's Confidential Information. Employee further acknowledges and agrees
that the Confidential Information, including any and all copies thereof,
constitutes trade secrets of Company and is confidential and proprietary
information of Company. Employee further acknowledges and agrees that he has no
right, title, interest or claim in or to any of the Confidential Information or
any copies thereof. Employee agrees to maintain the confidentiality of the
Confidential Information and agrees that he will not take, or permit to be
taken, any action with respect to the Confidential information (or any portion
thereof) which is inconsistent with the confidential and proprietary nature of
such information. Without limiting the generality of the foregoing, Employee
agrees that he will not, directly or indirectly, without the prior specific
written consent of Company, except as specifically required in the course of his
employment,

         (i)      communicate, divulge, transmit or otherwise disclose any
                  Confidential Information to any person, firm, partnership,
                  corporation or other entity, or

         (ii)     use any Confidential Information in any manner except as
                  specifically required in connection with the performance of
                  services hereunder.

         Employee agrees to take any and all steps reasonably necessary to
protect the confidentiality of the Confidential Information. Employee shall,
upon termination of this Agreement, immediately return to Company all
Confidential Information in Employee's control or possession, including, without
limitation, any and all copies thereof. This Section shall survive the
expiration or termination of this Agreement for a period of two (2) years.

         9. RESTRICTIVE COVENANT AND NON-COMPETITION.

                  9.01 UPON TERMINATION. As an independent covenant, Employee
         agrees that, for a period of two (2) years commencing upon the
         termination of this Agreement by expiration of its term or by the
         Company for cause, as provided in Section 12 of this Agreement,
         Employee will not, unless granted express written permission by the
         Board of Directors of Company, develop, work on or in any way advance,
         directly or indirectly, as an officer, director, stockholder, employee,
         advisor, consultant, partner, owner, agent, representative or in any
         other capacity, any competitor of Company or any other third party, any
         oil, gas and mineral exploration or production from the geographic
         areas, horizons, plays, formations or trends that the Company was
         studying to any significant extent during his employment; provided,
         however, that the foregoing shall not prohibit Employee from becoming a
         passive shareholder owning less than five percent (5%) of the shares of
         another corporation whose shares are publicly traded.

                  9.02 COMPANY EMPLOYEES. As an independent covenant, Employee
         agrees, during the term of this Agreement and, upon termination or
         expiration of this Agreement for any reason, for a period of eighteen
         (18) months thereafter, not to induce or attempt to influence any
         employee of Company to terminate his or her employment with Company.

                  9.03 REASONABLENESS. Employee acknowledges and agrees that the
         covenants and agreements set forth in this Section are made to protect
         the legitimate business interests of Company, including Company's
         interest in Confidential Information, and not to restrict his mobility
         or to prevent him from utilizing his skills. Employee recognizes and
         acknowledges the necessarily national and scope of the market served by
         Company and agrees that the restrictions set forth in this Section are
         reasonable.

                  9.04 SURVIVAL. This Section 9 shall survive the expiration or
         termination of this Agreement.


                                      -3-

         10. PERFORMANCE BY EMPLOYEE. Employee acknowledges and agrees that the
value of the Confidential Information and the success and long-term viability of
Company depends largely upon Employee's performance of his obligations under
Sections 8 and 9 of this Agreement.

         11. INJUNCTIVE RELIEF. Employee acknowledges and agrees that in the
event of any unauthorized use or disclosure of Confidential Information in
violation of the terms and conditions of Section 8 of this Agreement by
employee, or any breach of any of the terms and conditions of Section 9 of this
Agreement by Employee, Company will suffer irreparable injury not compensable by
money damages and, therefore, will not have an adequate remedy available at law.
Accordingly, if Company institutes an action or proceeding to enforce the
provisions of Section 8 or 9 of this Agreement, Company shall be entitled to
obtain such injunctive relief or other equitable remedy from a court of
competent jurisdiction as may be necessary or appropriate to prevent or curtail
any such breach, threatened or actual. The foregoing shall be in addition to and
without prejudice to such other rights as Company may have at law or in equity.

         12. TERMINATION.

                  12.01 TERMINATION. Employee's employment hereunder is
         terminable, with cause, at the will of either Company or Employee upon
         the giving of 30 days' prior written notice by either party; otherwise,
         it shall continue for the term of the Agreement as specified in section
         2, at which time it shall terminate. If Employee's employment is
         terminated for cause by the Company before the expiration of the term
         of the Agreement, Company shall discontinue Employee's compensation as
         of the effective date of the termination of Employee's employment. If
         Employee's employment is terminated for cause by the Employee, is
         terminated involuntarily, including, without limitation, termination
         resulting from the death or mental or physical disability of Employee,
         or is terminated without cause by the Company, Employee's regular
         compensation shall continue for the remainder of the term of the
         Agreement. For purposes of this Agreement, "for cause" shall mean:

                           (a) Any willful or intentional act of either Employee
                  or the Company that has or will have the effect of injuring
                  the reputation or business relationships of the other party or
                  its affiliates;

                           (b) The non-terminating party's conviction of or
                  entering a plea of nolo contendere to a charge of felony or a
                  misdemeanor involving dishonesty or fraud;

                           (c) The non-terminating party's material breach of
                  any of the terms, covenants or conditions contained in this
                  Agreement; provided, however, that with respect to any breach
                  that can be effectively cured by some act of a party,
                  termination of this Agreement shall be revoked if, within ten
                  (10) days after receipt of notice of such breach from the
                  non-breaching party, the breaching party cures such breach to
                  the reasonable satisfaction of the other party or, if such
                  cure cannot reasonably be accomplished within such ten (10)
                  day period, if the breaching party initiates efforts to cure
                  such breach within such ten (10) day period and diligently
                  pursues such cure efforts thereafter until such cure is
                  accomplished; or

                           (d) The non-terminating party's repeated or
                  continuous failure, neglect or refusal to perform its duties
                  under this Agreement.


                                      -4-
   5


         Until the effective date of termination, Employee, if requested to do
         so by Company, shall continue to render services to Company.

                  12.02 NO DUTY TO MITIGATE. Employee shall not be required to
         mitigate the amount of any post-employment payment or benefit paid or
         provided to Employee under this Agreement by seeking other employment
         or otherwise, nor shall the amount of any such payment or benefit paid
         or provided to Employee under this Agreement be reduced or offset by
         any compensation earned by Employee as the result of employment by
         another employer or otherwise.

         13. EFFECT OF TERMINATION. Upon the termination or expiration of this
Agreement: (i) Employee shall immediately return to Company any and all
Confidential Information in his possession or control (including, without
limitation, all copies thereof and all materials incorporating such Confidential
Information), (ii) Employee shall have no further obligation to perform services
for Company hereunder, provided, however, that Employee shall continue to be
bound by the terms of Sections 8 and 9 hereof, and (iii) except to the extent
specifically provided in Section 12 above, Company shall have no further
obligation to compensate or provide benefits to Employee hereunder.

         14. BUSINESS KNOWLEDGE AND EXPERIENCE. Notwithstanding anything to the
contrary contained in this Agreement, it is specifically understood and agreed
that Employee has, prior to entering into this Agreement, developed significant
business expertise, ideas and experience (collectively "Business Experience")
that such Business Experience, to the extent it applies to business operations
generally and not to the specific operations, technologies or trade secrets of
Company, shall not be deemed to constitute Confidential Information, and nothing
contained in Section 8 of this Agreement shall be deemed to prevent Employee
from using such general Business Experience in such a manner as does not violate
any of the other terms and conditions of this Agreement.

         15. GENERAL.

                  15.01 SURVIVAL OF REPRESENTATIONS, WARRANTIES AND COVENANTS.
         All representations, warranties and covenants contained herein shall
         survive the execution of this Agreement and the consummation of the
         transactions contemplated hereby.

                  15.02 SUCCESSORS AND ASSIGNS. This Agreement shall be binding
         upon and inure to the benefit of the parties hereto and their
         respective heirs, successors, assigns and legal representatives, but it
         shall not be assignable by Employee. Any purported assignment in
         violation of the foregoing shall be invalid and of no force and effect.
         No assignment of this Agreement shall relieve the assigning party of
         any obligation or liability hereunder.

                  15.03 NOTICES. Any notice, demand, payment, request, response
         or other communication provided for herein or given hereunder to a
         party hereto shall be in writing and shall be deemed to have been duly
         given if signed by the party giving it. Notice shall be deemed
         effective upon delivery by hand, or on the third business day after it
         is deposited in the United States mail, postage prepaid (registered or
         certified mail) or on the business day after it is sent by federal

         with the foregoing provisions.

                  15.04 WAIVER. Failure to delay in insisting upon strict
         compliance with any provision hereof shall not be deemed a waiver of
         such provision or any other provision hereof with respect to prior,
         contemporaneous or subsequent occurrences. No waiver by either party of
         any right hereunder or of any default shall be binding upon such party
         unless such waiver is in writing and signed by Employee (in the case of
         Employee) or a duly authorized officer of Company in the case of
         Company.

                  15.05 GOVERNING LAW; VENUE. This Agreement shall be governed
         by and construed in accordance with the laws of the State of Texas.
         Employee and Company hereby agreed that the sole and exclusive place of
         jurisdiction and venue for resolution of any disputes arising hereunder
         or relating hereto shall be San Antonio, Bexar County, Texas, and

         arrangements or understandings, oral or written, between the parties
         hereto relating to the employment relationship between Company and
         Employee that are not fully expressed in this Agreement. This Agreement
         may be amended only by a writing signed by both parties.

                  15.07 SEVERABILITY. The provisions of this Agreement are
         severable and the invalidity or unenforceability of any provision
         hereof shall not affect the validity or enforceability of any other
         provision. In addition, in the event that any provision of this
         Agreement (or portion thereof) is determined by a court to be
         unenforceable as drafted by virtue of the scope, duration, extent or
         character of any obligation contained therein, the parties acknowledge
         that it is their intention that such provision (or portion thereof)
         shall be construed in a manner designed to effectuate the purposes of
         such provision to the maximum extent enforceable under applicable law.

                  15.08 ATTORNEYS' FEES. If any legal action or other proceeding
         is brought for the enforcement of this Agreement, or because of an
         alleged dispute, breach, default or misrepresentation in connection
         with any of the provisions of this Agreement, the prevailing party
         shall be entitled to recover reasonable attorneys' fees and other costs
         incurred in that action or proceeding, in addition to any other relief
         to which it may be entitled.

                  15.09 REMEDIES CUMULATIVE. All remedies provided for in this
         Agreement shall be cumulative and in addition to, and not in lieu of,
