THIS EMPLOYMENT AGREEMENT (this "Agreement") is dated and effective as of October 1, 2002 (the "Effective Date"), by and between CARBON ENERGY CORPORATION,
a Colorado corporation, with offices at 1700 Broadway, Suite 1150, Denver, Colorado 80290-1101 ("Company"), and PATRICK R. McDONALD, residing in Colorado ("Executive").

RECITALS

WHEREAS, Company desires to acquire the services of Executive, and Executive desires to be employed by Company upon the terms and conditions set forth in this
Agreement.

AGREEMENT

NOW THEREFORE, in consideration of these premises and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the
parties hereto do hereby agree as follows:

Article I.
Term of Employment

1.1Position and Employment Period.Company hereby employs Executive as its President and Chief Executive
Officer, and Executive hereby accepts employment with Company, all in accordance with the
terms and conditions hereof, for an initial three-year term commencing on the Effective Date and ending three years from that date, unless otherwise terminated as provided in
Section 1.3 or Articles IV and V. This Agreement shall continue from year to year thereafter unless Company gives written notice of termination to Executive at least three months
preceding the date of termination or Executive gives such notice to Company on or at least three months preceding the date of termination (the initial three-year term is referred to
as the "Initial Employment Period," and together with any subsequent periods of employment pursuant hereto, the "Employment Period").

1.2Appointment as Director.Company agrees that for so long as Executive is an officer of Company,
Company shall nominate and endorse Executive to serve as a director on Company's Board of
Directors.

1.3Change in Control.



In
determining whether clause (i) of the preceding sentence has been satisfied, the third person owning shares must be someone other than Yorktown Energy Partners III, L.P., Yorktown
Partners LLC, or entities controlled by Yorktown Partners LLC. For this purpose, the term "controlled" means possession, direct or indirect, of the power to direct or cause the direction of the
management and policies of a person, whether (1) through the ownership of more than 50% of the outstanding voting securities of the person, (2) by contract or (3) by a position
such as a general partner or manager.



Article II.
Duties

2.1Duties.During the term hereof:



Article III.
Compensation

3.1Salary.Company shall pay Executive a base salary of not less than $242,000 per year plus an adjustment
on each July 1 hereafter for all cost of living increases
(computed by dividing the preceding year's U.S. consumer price index by the year preceding such year's U.S. consumer price index and multiplying such percentage by the then base salary), to be paid at
the usual times for the payment of Company's executives, subject to adjustment as provided herein. Executive's base salary shall be reviewed annually by the Board of Directors of Company and may be
increased, but not decreased. Incentive compensation or bonuses (called in this Agreement incentive compensation) will be determined by the Board of Directors at its discretion.

3.2Benefits; Life Insurance.Executive shall be entitled to receive all benefits (such as medical,
dental, disability and life insurance and paid vacation (a maximum of four weeks)).
Executive shall be eligible to participate in all incentive compensation, stock option, performance unit or similar plans or programs as the Board of Directors of Company may determine in its
reasonable discretion based upon Company's compensation practices and Executive's responsibilities and performance. Company shall provide without cost to Executive the following: membership fees and
dues relating to organizations to which Executive has historically belonged and subscription costs for publications relevant to Company's business which Executive has historically received. So long as
Executive is employed under this Agreement and during the 24 months specified in Section 5.1(b), Company shall maintain for the benefit of Executive's estate, and pay the premiums for, a
life insurance policy on Executive's life in the amount of $2,000,000.

3.3Reimbursement of Expenses.In addition, Company shall promptly reimburse Executive for all
reasonable and documented out-of-pocket expenses incurred in the
performance of his duties hereunder, including without limitation, expenses for entertainment, travel, management seminars and the like.

Article IV.
Death, Disability and Termination

4.1Death.If Executive dies during the Employment Period, the Employment Period shall thereupon terminate
for all purposes of this Agreement, and Company's obligations
hereunder shall


terminate immediately, and Executive's estate or legal representative shall be entitled only to the following:



4.2Disability.If Executive is unable to perform his duties as required under this Agreement by
reason of mental or physical illness or incapacity, Company agrees to continue
all payments due hereunder, including salary, for a period of 180 days from the date of disability. Notwithstanding anything to the contrary contained herein, Executive shall be considered
disabled and Company may terminate this Agreement at any time Executive shall be absent from employment as a result of mental or physical illness or incapacity for a continuous period of
180 days, and all obligations of Company hereunder shall cease upon any such termination. Upon any such termination, Executive shall be entitled only to the following:



4.3Disability Insurance.While Executive is employed under this Agreement, during the period
specified in Section 5.1(b) and after the period described in
Section 5.1(b) if this Agreement is terminated because of Executive's disability, Company shall provide, for the benefit of Executive, a disability insurance policy, with mutually
agreeable terms determined within 60 days of the Effective Date, the premiums of which shall be paid by Company.

4.4Determination of Disability.For purposes of this Agreement, if at any time a question arises as
to the disability of Executive, then Company and Executive shall agree on one physician who is
a member of the American Medical Association to examine Executive and determine if his physical and/or mental condition is such as to render him incapable of performing the usual duties of his
employment with Company.

4.5Termination.In addition to the foregoing provisions, the Employment Period and Executive's
employment with Company may be terminated by:



Article V.
Termination Benefits

5.1Severance Payments.Subject to the provisions of Section 1.3 hereof, (i) if Executive's
employment shall be terminated by the Board of Directors of Company for any
reason other than "for cause" or upon the death or disability of Executive, or (ii) if Executive voluntarily terminates employment in accordance with Section 4.5(b) following a
change in position with Company from that described in Section 1.1 or because of any other material breach of this Agreement by Company, then Company shall pay Executive a termination benefit
as follows:



5.2Termination for Cause.If Executive is terminated for cause, then he shall receive no further
benefits hereunder. "Cause" shall mean a termination on account of (1) repeated
refusal to obey written directions of the Board of Directors or a superior officer (so long as such directions do not involve illegal or immoral acts); (2) repeated acts of substance abuse
which are materially injurious to Company or any of its subsidiaries, (3) fraud or dishonesty that is materially injurious to Company or any of its subsidiaries, (4) breach of any
material obligation of nondisclosure or confidentiality owed to Company or any of its subsidiaries, (5) commission of a criminal offense involving money or other property of Company (excluding
any traffic violations or similar violations), or (6) commission of a criminal offense that constitutes a felony in the jurisdiction in which the offense is committed.

5.3Certain Additional Payments by Company.Notwithstanding anything to the contrary in this
Agreement, in the event that any payment or distribution by Company to or for the benefit of the Executive,
whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise (a "Payment"), would be subject to the excise tax imposed by Section 4999 of the
Internal Revenue Code or any interest or penalties with respect to such excise tax (such excise tax, together with any such interest or penalties, are hereinafter collectively referred to as the
"Excise


Tax"), Company shall pay to Executive an additional payment (a "Gross-up Payment") in an amount such that after payment by Executive of all taxes (including any interest or penalties
imposed with respect to such taxes), including any Excise Tax imposed on any Gross-up Payment, Executive retains an amount of the Gross-up Payment equal to the Excise Tax
imposed upon the Payments. Company and Executive shall make an initial determination as to whether a Gross-up Payment is required and the amount of any such Gross-up Payment.
Executive shall notify Company immediately in writing of any claim by the Internal Revenue Service which, if successful, would require such Gross-up Payment (or a Gross-up
Payment in excess of that, if any, initially determined by Company and Executive) within five days of the receipt of such claim. Company shall notify Executive in writing at least five days
prior to the due date of any response required with respect to such claim if it plans to contest the claim. If Company decides to contest such claim, Executive shall cooperate fully with Company in
such action; provided, however, Company shall bear and pay directly or indirectly all costs and expenses (including additional interest and penalties) incurred in connection with such action and shall
indemnify and hold Executive harmless, on an after-tax basis, for any Excise Tax or income tax, including interest and penalties with respect thereto, imposed as a result of Company's
action. If, as a result of Company's action with respect to a claim, Executive receives a refund of any amount paid by Company with respect to such claim, Executive shall promptly pay such refund to
Company. If Company fails to timely notify Executive whether it will contest such claim or Company determines not to contest such claim, then Company shall immediately pay to Executive the portion of
such claim, if any, which it has not previously paid to Executive.

Article VI.
Covenants of Executive

6.1Confidential Information.Executive covenants and agrees that he will not at any time during or after
the termination of his employment, whether under this Agreement, or otherwise, reveal,
divulge or make known to any person any confidential or proprietary information ("Confidential Information") whatsoever made known to Executive by reason of his employment by Company. This
Section 6.1 shall not apply to information made known to Executive by reason of his outside personal business interests or personal investments made in accordance with this Agreement. In the
event of a breach or threatened breach by Executive of the provisions of this Section 6.1, Company shall be entitled, in addition to any remedy hereunder or under any applicable law, to an
injunction restraining Executive from disclosing or using, in whole or in part, any Confidential Information. The covenants contained in this Section 6.1 shall survive the termination or
expiration of this Agreement for a period of 24 months.

Article VII.

obligations hereunder, then Company shall pay reasonable counsel fees
incurred by Executive in connection with such disagreement, if Executive prevails in his position.

instruments in writing signed by the party against whom enforcement or any such
modification or amendment is sought. Either party hereto may, by an instrument in writing, waive compliance by the other party with any term or provision of this Agreement on the part of such other
party hereto to be performed or complied with. The waiver by any party hereto of a breach of any term or provision of this Agreement shall not be construed as a waiver of any subsequent breach.

7.6Section Headings.The section and other headings contained in this Agreement are for
reference purposes only and shall not be deemed to be a part of this Agreement or to

unenforceable, in whole or in part, by a court of competent jurisdiction, this
Agreement shall be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of this Agreement.
