"Effective Date") by and between Vista Exploration Corporation, a Colorado
corporation ("Employer"), and Charles A. Ross, Sr. ("Employee").

     1. Employment. Employer hereby employs Employee and Employee hereby accepts
such employment, subject to the terms and conditions of this Agreement. Employee
shall serve in the capacity of President, report directly to the Board of
Directors and shall perform such functions as the Board of Directors of Employer
shall determine from time to time; provided, however, that Employee's duties
shall always be professional in nature and shall utilize and be consistent with
the training, talent and ability of Employee.

     2. Full-Time Best Efforts. Employee shall devote essentially his full
professional time and attention to the performance of his obligations under this
Agreement, and shall at all times perform all of his obligations hereunder to
the best of his ability, experience and talent.

     3. Term and Termination. The term of this Agreement shall commence on the
Effective Date and shall continue uninterrupted for a period of one (1) year,
unless sooner terminated or extended year-to-year by mutual agreement or as
provided below in this Section 3. Failure to agree to an extension shall not be
deemed a termination but only a lapse of the employment. This Agreement may be
otherwise terminated as follows:

          (a) Employer may terminate the employment of Employee hereunder:

               (i) upon the death of Employee;

               (ii) upon Employee's inability, by reason of sickness or other
          disability, to perform his obligations hereunder for more than ninety
          (90) consecutive days;

               (iii) upon a showing of good cause, which for purposes of this
          Agreement shall mean: (A) Employee's failure to act in accordance with
          this Agreement or any other breach of this Agreement by Employee; (B)
          Employee's willful misconduct, negligence or incompetence in the
          discharge of his duties hereunder; or (C) Employee's commission of any
          act detrimental to Employer or any act of moral turpitude; provided,
          however, that prior to terminating Employee pursuant to clause (A) or
          (B), Employer shall give Employee at least thirty (30) business days'
          written notice of an intent to terminate due to such failure to act or
          breach, which notice shall specify such failure or breach, and, if
          Employee cures such failure or breach within such thirty (30) day
          period, this Agreement shall remain in full force and effect; or

               (iv) after the initial term of this Agreement, for any reason
          upon thirty (30) days' prior written notice; provided that if Employee
          is terminated pursuant to this Section 3(a)(iv): (i) Employer shall
          pay Employee a severance benefit equal to six (6) month's salary for
          each full year of service Employee has completed for Employer; and
          (ii) Employer shall additionally provide Employee and his dependents
          up to six months' health care insurance continuation following the
          date of termination. Notwithstanding the foregoing, benefits shall be
          reduced to the extent that comparable benefits are provided to
          Employee and his dependents by another employer. At its option,
          Employer may pay thirty (30) days of additional compensation in lieu
          of the thirty (30) days' prior notice set forth above.


          (b) Employee may terminate his employment hereunder upon at least
     thirty (30) days' prior written notice to Employer.

     4. Compensation. In consideration for his services, Employer shall pay
Employee a base salary at the rate of Sixty Thousand Dollars ($60,000) per
annum. Employee's salary hereunder shall be payable in bi-monthly installments,
or on such other payment schedule as is used to pay similarly situated employees
of Employer. Employee shall be eligible for annual increases in base salary as
determined by the Board of Directors of Employer in its sole discretion based
upon Employee's performance and the financial performance of Employer. Employee
agrees to defer the receipt of his salary for a period of (i) up to six (6)
months; (ii) the Employer has received an additional Two Hundred Thousand
Dollars ($200,000) in debt or equity capital infusion; (iii) the Employer starts
receiving revenue from operations; or (iv) there is a change of control
requiring an 8-K filing, whichever first occurs.

     5. Stock Options Grant. Employee is hereby granted options exercisable for
a period of five years to purchase five hundred thousand (500,000) shares of the
Employer's common stock at an exercise price $.10 per share (current market
value as of the date hereof). The options shall be fully vested as of the date
of this grant. Employer shall use its best efforts to register the common shares
underlying the options grant within ninety (90) days of the date of this
Agreement. Should the Employee terminate his employment with the Employer during
the term of this Agreement or should his employment be terminated, the Employee
shall have a period of one hundred eighty (180) days to exercise his options or
they shall expire.

     6. Employee Benefits. Employee shall be entitled to such employee benefits
as are from time to time made available generally by Employer to similarly
situated employees, including paid vacation and sick leave, health, retirement
benefits, dental and vision insurance, life insurance, disability insurance and
office amenities.

     7. Miscellaneous.

     between the parties with respect to the subject matter hereof and

          (b) Severability. If any provision of this Agreement shall be held to
     be invalid, illegal or unenforceable, such provision may be severed or
     enforced to the extent possible, and such invalidity, illegality or
