                         NET PROFITS INTEREST BONUS PLAN
                         -------------------------------

            As Amended by the Board of Directors on February 3, 2004


         The Net Profits Interest Bonus Plan of St. Mary Land & Exploration
Company shall function as follows:

         1. Each year the Board of Directors of the Company shall designate the
key employees of the Company eligible to participate in the Net Profits Interest
Bonus Plan with respect to that calendar year. It is anticipated that such
participants shall be more senior employees and fewer in number than the
designated participants in the Company's Cash Bonus Plan.
         2. Participants in the Net Profits Interest Bonus Plan shall receive a
net profits interest in the Company's interest in oil and gas wells completed,
plugged or abandoned or acquired by the Company during the calendar year (the
"Plan Year"). The aggregate amount of such net profits interest of all
participants for such Plan Year shall be ten percent which interest shall apply
after recovery by the Company from such wells of one hundred percent of all
costs and expenses incurred by it with respect thereto, including but not
limited to land, geological and geophysical costs but excluding (except as
described in paragraph 4 below) interest, and such net profits interest shall
increase to an aggregate of twenty percent from and after such time as the
Company has recovered two hundred percent of all such costs and expenses
incurred by it with respect to such wells, including prior compensation expenses
resulting from application of the Net Profits Interest Bonus Plan at the
preceding ten percent interest level. For purposes of the foregoing
calculations, such wells shall be accounted for as a single pool (effective
January 1, 1999 except as described in paragraph 4 below). In determining net



profits, any recompletion, workover or similar expenditures for wells shall be
charged against the revenues of such wells, as well as direct lease operating
expenses, production taxes and overhead as determined solely by COPAS charges in
the relative areas.
         3. Each key employee participating in the Net Profits Interest Bonus
Plan with respect to a Plan Year shall be allocated a portion of the net profits
interest for such Plan Year in proportion to his or her weighted base salary
received during such Year relative to the weighted base salary received by all
participants during such Plan Year. The weighted base salary of the President
and of the Executive Vice Presidents of the Company shall be one hundred percent
of their base salaries received during such Plan Year and of all other
participants shall be two-thirds thereof; provided, however, that a reduced
participation rate may be established by the Board of Directors for certain key
employees whose duties involve them in only a portion of the Company's
activities.
         4. The Board of Directors, in its discretion, may consider a
significant acquisition or a multi-year project to be accounted for as a
separate pool with respect to the Net Profits Interest Bonus Plan as follows:

                  (a) If the total costs incurred is greater than 75% of the
         average annual aggregate cost during the current year and the preceding
         two calendar years, the net profits interest of the participants with
         respect to such large acquisition or multi-year project shall be a
         portion of the ten percent and twenty percent amounts set forth in
         paragraph 2 above equal to such percentages multiplied by a fraction of
         which the numerator is 75 percent and the denominator is the percentage

                                      -2-


         which the cost of such acquisition or multi-year project is of the
         average annual aggregate costs expended by the Company for all other
         oil and gas wells during such year and during the preceding two
         calendar years (but exclusive of the foregoing and any other projects
         designated as separate pools); and
                  (b) Recovery of the Company's costs of such large acquisition
         or multi-year project shall include interest thereon calculated at the
         prime rate in effect from time to time;
                  (c) Notwithstanding the provisions of paragraph 3 above,
         participants in the Net Profits Interest Bonus Plan with respect to
         such large acquisition shall be allocated a portion of the net profits
         interest with respect thereto based upon their weighted base salaries
         for the calendar year such large acquisition closed. The net profits
         interest in a multi-year project shall be allocated among the
         participants in the Net Profits Interest Bonus Plan for the calendar
         years in which the costs for such project are incurred until the
         project is deemed to be substantially complete on the basis of their
         weighted base salaries during such years;
                  (d) A transaction in which the Company acquires another
         company, or is acquired or merges, or otherwise acquires what is
         considered by the Compensation Committee of the Board of Directors of
         the Company another oil and gas business (in which event the
         Compensation Committee shall determine what other incentive
         compensation is appropriate, if any), as contrasted with what is
         considered a more customary acquisition of oil and gas properties,
         shall not constitute the acquisition of an oil and gas well project

                                      -3-


         subject to the Net Profits Interest Bonus Plan.

         5. Subject to the Plan Year buyout provision in paragraph 8, the right
to a portion of a net profits interest of a designated participant in the Net
Profits Interest Bonus Plan shall vest in full in such participant on December
31 of the calendar year for which his or her participation is designated,
provided that the participant's employment by the Company did not terminate
prior to that date for reasons other than retirement or death. Termination of a
participant's employment by the Company subsequent to that time shall not affect
his or her right to a portion of such net profits interest.
         6. Allocations or payments to participants under the Net Profits
Interest Bonus Plan shall not be deemed to constitute compensation of any nature
for purposes of any other compensation, retirement or other benefit plan of the
Company. To the extent that any such other plan contains provisions contrary to
the foregoing sentence, such other plan shall be deemed to be amended to conform
to the foregoing sentence.
         7. Net profits interests allocated under the Net Profits Interest Bonus
Plan shall not constitute for the participants therein the ownership of real
property interests in the mineral properties of the Company. Rather such net
profits interests shall constitute solely a right to receive payments from the
Company, or from a fund or trust established by the Company for that purpose,
the amount of which shall be determined by such net profits interests and the
Net Profits Interest Bonus Plan.
         8. Payments to participants under the Net Profits Interest Bonus Plan
shall be made annually, or more frequently as determined by the Board of
Directors. The right to payments under the Net Profits Interest Bonus Plan shall

                                      -4-


not be subject to voluntary or involuntary assignment by any participant
thereunder other than as follows:

                  (a) upon death pursuant to:
                           (i) a will;
                           (ii) the laws of descent and distribution; or
                           (iii) a beneficiary designation form approved by the
                  Company and executed by the participant which designates the
                  persons or entities to receive, upon the participant's death,
                  the right to payments under the Net Profits Interest Bonus
                  Plan which the participant had upon the participant's death;
                  or

                  (b) pursuant to a qualified domestic relations order, as
         defined under Section 414(p) of the Internal Revenue Code of 1986,
         relating to the provision of child support, alimony payments, or
         marital property rights to a spouse, former spouse, child or other
         dependent of the participant.

         The Company shall have the right to require that any recipient of
payments under the Net Profits Interest Bonus Plan who is not an employee of the
Company at the time of payment shall be responsible for the payment of all
amounts required to satisfy all federal, state and local withholding taxes
applicable to such recipient with respect to such payments under the Net Profits
Interest Bonus Plan. The Company shall have the right at any time or from time
to time to acquire the rights of all participants in any Plan Year if the
participants holding no less than two-thirds of that Plan Year's interests have
agreed in writing to the terms and conditions of a buy-out of that Plan Year.

                                      -5-


         9. All matters with respect to the interpretation and application of
the Net Profits Interest Bonus Plan shall be conclusively determined by the
Compensation Committee of the Board of Directors of the Company.
         10. The Net Profits Interest Bonus Plan may be terminated or modified
prospectively at any time by the Board of Directors. Nothing contained in the
Net Profits Interest Bonus Plan shall constitute a contract, express or implied,
or any other type of obligation with respect to the employment or the continued
employment by the Company of any person.

                                      -6-
