                         NET PROFITS INTEREST BONUS PLAN
                         -------------------------------
                                                                   As Amended on
                                                                9/19/96, 7/24/97
                                                                     and 1/28/99


         The Net Profits  Interest  Bonus  Plan  of St. Mary Parish Land 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  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.  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.

                                      -1C-



         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
         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
         subject to the Net Profits  Interest Bonus Plan. 

                                      -2C-



         5. Subject to the Plan Year buyout provision of  paragraph 9, 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. Mining  projects of the Company shall be accounted for as a separate
pool for  purposes  of the Net Profits  Interest  Bonus Plan and the net profits
interests  with  respect  thereto.  The Board of  Directors  of the  Company may
determine  that  employees  of the Company  whose time is  primarily  devoted to
mining projects shall not participate  under the Net Profits Interest Bonus Plan
in net  profits  interests  in oil and gas  project  pools and  conversely  with
respect to employees whose time is primarily devoted to oil and gas projects and
net profits interests in mining projects.

         7.  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.

         8. 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.

                                      -3C-



         9. Payments to participants  under the Net Profits  Interest Bonus Plan
shall be made  annually,  or more  frequently as determined by the Company.  The
right to payments under the Net Profits Interest Bonus Plan shall not be subject
to voluntary or involuntary  assignment by any participant thereunder other than
upon death pursuant to the laws of descent and  distribution.  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.

         10. 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.

         11. 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.
