1.Employment.The Company hereby agrees to employ Employee, and Employee hereby agrees to render his exclusive
service to the Company, in the capacity of Chairman of the Board, Chief Executive Officer and President of the Company, with such duties as may be assigned to him from time to time by the Board of
Directors of the Company (the "Board") for the period commencing on the date hereof and ending on December 31, 2005 (the
"Employment Period"), subject to earlier termination as hereinafter provided.

this Agreement, Employee's business office shall be located in Denver, Colorado, at such location in the Denver metropolitan area as may be specified by the Board.

3.Compensation.Employee shall be compensated by the Company at a minimum base rate of Three Hundred Fifty
Thousand and No/100 Dollars ($350,000.00) per annum, payable semi-monthly on the fifteenth and final days of each month during the Employment Period, subject to such increases and
additional payments as may be determined from time to time by the Board in its sole discretion. Such compensation shall be in addition to any group insurance, pension, profit sharing and other
employee benefits, including the Company's existing employee benefit plans, which are extended from time to time to Employee in the discretion of the Board and for which Employee is eligible. Subject
to such
rules and procedures as are from time to time specified by the Company, the Company shall also reimburse Employee for all reasonable expenses incurred by him on behalf of the Company.

4.Performance of Services.Employee shall devote his full working time to the business of the Company (which
may include service on oil and gas industry association boards consistent with the Company's business interests);provided,however, Employee shall be
excused from performing any services for the Company hereunder during periods of temporary incapacity and during vacations conforming to the Company's standard vacation policy (which for Employee
shall be a minimum of four weeks per year), without thereby in any way affecting the compensation to which he is entitled hereunder.

5.Noncompetition.Employee agrees that during his employment by the Company and for so long thereafter as he is
receiving Severance Benefit Payments (as such term is defined in Section 10), he will not, directly or indirectly, either through any kind of ownership (other than ownership of securities of
publicly held corporations of which Employee owns less than one percent (1%) of any class of outstanding securities) or as a director, officer, agent, employee or consultant, engage in any business
which is competitive with the business of the Company within the states of Texas, Wyoming, Utah and Colorado as well as the province of Alberta. It is expressly agreed that the remedy at law for
breach of this covenant is inadequate and that injunctive relief shall be available to prevent the breach thereof. Employee shall be relieved from the restrictions of this Section 5 only in the
event Employee is terminated due to Trigger Events in accordance with the Severance Agreement (as defined in Section 20).

6.Continuing Obligations.In order to induce the Company to enter into this Agreement, Employee hereby agrees
that all non-public documents, records, techniques, business secrets and other information which have come into his possession from time to time during his employment by the Company or which may come into his possession during his employment hereunder, shall be deemed to be
confidential and proprietary to the Company and Employee further agrees to retain in confidence any confidential information known to him concerning the Company and its subsidiaries and their
respective businesses so long as such information is not publicly disclosed by the Company in the ordinary course of the Company's business; provided, however, that the express obligation to retain
such confidence shall expire eighteen (18) months after Employee's termination of employment. In the event of a breach or threatened breach by Employee of the provision of this
Section 6, the Company shall, in addition to any other available remedies, be entitled to an injunction restraining Employee from disclosing, in whole or in part, any such information or from
rendering any services to any person, firm or corporation to whom any of such information may have been disclosed or is threatened to be disclosed.

7.Property of Company.All data, drawings and other records and written material prepared or compiled by
Employee or furnished to Employee while in the employ of the Company shall be the sole and exclusive property of the Company, and none of such data, drawings or other records, or copies thereof, shall
be retained by Employee upon termination of his employment.

8.Surviving Provisions.The provisions of Sections 5 (for so long as Employee is receiving Severance
Benefit Payments), 6 and 7 of this Agreement shall continue to be binding upon Employee in accordance with their terms, notwithstanding termination of Employee's employment hereunder for any reason.

9.Termination for Cause.It is agreed and understood that the Company can terminate the employment of Employee
under this Agreement without obligation to pay the Severance Benefit Payment (as described below) or any other obligation under this Agreement if such termination is for cause, and that, without
prejudice to the generality of the right to terminate for cause, each of the following contingencies shall be examples of cause:



The
Company may for cause terminate Employee's employment under this Agreement without advance notice, except as otherwise specifically provided for in respect of cureable situations.
Termination shall not affect any of the Company's other rights and remedies.

10.Severance Benefit Payment.Upon the occurrence of a Severance Event (as defined below) and Employee's
resignation from or termination of employment as a result thereof, the Company shall, in lieu of any other payment obligation under this Agreement, provide Employee with a severance benefit payment in
an amount equal to Employee's then existing annual base pay plus an amount equal to an average of Employee's three previous annual cash bonuses (collectively, the "Severance
Benefit Payment") plus continuation of medical and dental plan coverage (subject to the terms of such plans and to Employee's making any required contributions thereto) for a
period of one year from such resignation or termination. For purposes of this Agreement, a "Severance Event" is any one of the events specified in
subsections (a) through (d) below:



The
Severance Benefit Payment shall be paid to Employee in semi-monthly installments in the same amounts and at the same times as Employee's base pay was being paid at the
time of the Severance Event, until the full amount of the Severance Benefit Payment has been paid.

11.Payment of Certain Costs of Employee.If a dispute arises regarding a termination of Employee or the
interpretation or enforcement of this Agreement, all legal fees and expenses incurred by Employee in contesting or disputing any such termination or seeking to obtain or enforce any right or benefit
provided for in this Agreement or in otherwise pursuing his claim will be paid by the Company, to the extent Employee prevails. The Company further agrees to pay prejudgment interest on any money
judgment obtained by Employee calculated at the J. P. Morgan Bank prime interest rate in effect from time to time from the date that payment(s) to him should have been made under this Agreement.

12.Mitigation.Employee is not required to mitigate the amount of any payments to be made by the Company
pursuant to this Agreement by seeking other employment or otherwise.

13.Successors.(a) The Company will require any successor (whether direct or indirect, by purchase,
merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Company, by agreement in form and substance satisfactory to Employee, to expressly assume and agree
to perform this Agreement in the same manner and to the same extent that the Company would be required to perform if no such succession had taken place. Failure of the Company to obtain such agreement
prior to the effectiveness of any such succession shall be a breach of this Agreement and shall entitle Employee to compensation from the Company in the same amount and on the same terms as Employee
would be entitled hereunder if he were to terminate his employment pursuant to subsections 10(a), 10(b), 10(c) or 10(d). As used in this Agreement,
"Company" shall mean the Company as hereinbefore defined and any successor to its business and/or assets as aforesaid which executes and
delivers the agreement provided for in this Section 13 or which otherwise becomes bound by all the terms and provisions of this Agreement by operation of law.

(b)  This
Agreement shall inure to the benefit of and be enforceable by Employee's personal or legal representatives, executors, administrators, successors, heirs,
distributees, devisees and legatees. If Employee should die during the term hereof, the Company shall pay an amount equal to any amounts then payable to Employee hereunder, plus an amount equal to
three months' salary, with all such amounts to be paid to Employee's devisee, legatee or other designee or, if there be no designee, to his estate.

14.No Inconsistent Obligation.Employee represents and warrants that he has not previously assumed any
obligations inconsistent with those of this Agreement.

15.Modification.This Agreement shall be in addition to all previous agreements, written or oral, relating to
Employee's employment by the Company, and shall not be changed orally, but only by a written instrument to which the Company and Employee are both parties.

16.Binding Effect.This Agreement and the rights and obligations hereunder shall be binding upon and inure to
the benefit of the parties hereto and their respective legal representatives, and shall also bind and inure to the benefit of any successor of the Company by merger or consolidation or any assignee of
all or substantially all of its properties.

17.Law Governing.This Agreement is made, accepted and delivered in Denver, Colorado, is performable in Denver,
Colorado, and it shall be construed and enforced according to the laws of the State of Colorado. Venue shall lie in the City and County of Denver, Colorado for the purpose of resolving and enforcing
any dispute which may arise under this Agreement and the parties agree that they will submit themselves to the jurisdiction of the competent State or Federal Court situated in the City and County of
Denver, Colorado.

18.Invalid Provision.In case any one or more of the provisions contained in this Agreement shall be invalid,
illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be impaired thereby.

19.Notice.For purposes of this Agreement, notices and all other communications provided for herein shall be in
writing and shall be deemed to have been duly given when delivered or mailed by United States registered or certified mail, return receipt requested, postage prepaid, addressed as follows:

If

20.Effective May 3, 1999, Employee and the Company entered into that certain Severance Agreement (as amended
May 10, 2001, the "Severance Agreement") which provides Employee with compensation in the event of a Change in Control or an Asset Acquisition
(each as defined therein and collectively referred to herein as "Trigger Events").    Notwithstanding anything to the contrary set forth in
this Agreement, if Employee's employment with the Company is terminated such that the provisions of the Severance Agreement are applicable to Employee, Employee shall have the option to accept the
greater of the benefits of this Agreement or the Severance Agreement (which benefits are intended to be mutually exclusive and not cumulative upon a termination in conjunction with the occurrence of
either of the Trigger Events).

IN
WITNESS WHEREOF, the parties have executed this Agreement as of the date first above written.
