proprietary interest in the Company's success.

     All Employees are eligible to participate in the Plan and receive Incentive
Stock  Options  under the Plan.  Optionees  in the Plan shall be selected by the
Board, in its sole discretion, from among those Employees who, in the opinion of
the Board, are in a position to contribute materially to the Company's continued
growth and development and to its long-term financial success.

                                   ARTICLE IV
                                 ADMINISTRATION

     The Board shall be responsible for administering the Plan.

          (a) The Board is  authorized  to  interpret  the Plan;  to  prescribe,
     amend,  and rescind rules and regulations  relating to the Plan; to provide
     for conditions and assurances  deemed necessary or advisable to protect the
     interests of the Company; and to make all other determinations necessary or
     advisable   for   the   administration   of   the   Plan.   Determinations,
     interpretations,  or other  actions made or taken by the Board with respect
     to the Plan and Options  granted  under the Plan shall be final and binding
     and conclusive for all purposes and upon all persons.

          (b) At the discretion of the Board the Plan may be  administered  by a
     Committee of two or more non-employee Directors appointed by the Board (the

     any persons  having any interests in any Options which may be granted under
     the Plan, and, by resolution or resolutions to provide for the creation and
     issuance of any Option,  to fix the terms upon which,  the time or times at
     or within  which,  and the price or prices at which any shares of Stock may
     be purchased  from the Company upon the exercise of an Option.  Such terms,
     time or times and price or prices  shall,  in every  case,  be set forth or
     incorporated  by reference in the instrument or  instruments  evidencing an
     Option, and shall be consistent with the provisions of the Plan.

                                      -3B-


          (c) Where a Committee  has been created by the Board  pursuant to this
     Article  IV,  references  in the Plan to  actions  to be taken by the Board
     shall be deemed to refer to the Committee as well,  except where limited by
     the Plan or by the Board.

          (d) No member of the Board or the  Committee  shall be liable  for any
     action or determination  made in good faith with respect to the Plan or any
     Option granted under it.

     5.1 Number.  The total number of shares of Stock hereby made  available and
reserved for issuance  under the Plan upon  exercise of Options shall be 700,000
shares.  Notwithstanding anything to the contrary contained in the foregoing, to
the extent that  options are issued  under any other  current  Stock Option Plan
adopted by the Company,  the shares of Stock  reserved for issuance  pursuant to
Options granted under the Plan shall be reduced.  The aggregate number of shares
of Stock  available under the Plan shall be subject to adjustment as provided in
Section 5.3.

     5.2 Unused  Stock.  If an Option shall  expire or terminate  for any reason
without having been exercised in full, the  unpurchased  shares of Stock subject
thereto shall (unless the Plan shall have terminated) become available for other
Options under the Plan.

     5.3  Adjustment  in  Capitalization.  In the  event  of any  change  in the
outstanding   shares  of  Stock  by  reason  of  a  stock   dividend  or  split,
recapitalization,   reclassification,  or  other  similar  capital  change,  the
aggregate  number  of  shares  of  Stock  set  forth  in  Section 5.1  shall  be
appropriately adjusted by the Board, whose determination shall be conclusive. In
any such case,  the  number and kind of shares of Stock that are  subject to any
Option and the Option price per share shall be proportionately and appropriately
adjusted  without any change in the  aggregate  Option price to be paid therefor
upon exercise of the Option.

                                   ARTICLE VI
                              DURATION OF THE PLAN

     Subject to  approval of  shareholders,  the Plan shall be in effect for ten
years from the date of its adoption by the Board. Any Options outstanding at the
end of such period shall remain in effect in  accordance  with their terms.  The
Plan shall  terminate  before the end of such period if all Stock  subject to it
has been purchased pursuant to the exercise of Options granted under the Plan.

                                   ARTICLE VII
                             TERMS OF STOCK OPTIONS

     7.1 Grant of  Options.  Subject to  Section 5.1,  Options may be granted to
Employees  at any time and from time to time as  determined  by the  Board.  The
Board shall have complete discretion in determining the terms and conditions and
number of Options granted to each Optionee.  In making such determinations,  the
Board may take into account the nature of services  rendered by such  Employees,
their  present and  potential  contributions  to the Company and its  Subsidiary
Corporations,  and such other factors as the Board in its discretion  shall deem
relevant.

                                      -4B-


          (a) The total Fair Market Value  (determined  at the date of grant) of
     shares of Stock with respect to which  incentive  stock options granted are
     exercisable  for the first time by the Optionee  during any  calendar  year
     under all plans of the Company under which  incentive  stock options may be
     granted (and all such plans of any Parent  Corporations  and any Subsidiary
     Corporations of the Company) shall not exceed $100,000.  Hereinafter,  this
     requirement is sometimes referred to as the "$100,000 Limitation".

          (b) The Board is expressly  given the  authority  to issue  amended or
     replacement  Options with  respect to shares of Stock  subject to an Option
     previously  granted  hereunder.  An amended  Option  amends the terms of an
     Option  previously  granted and thereby  supersedes the previous  Option. A
     replacement Option is similar to a new Option granted hereunder except that
     it provides  that it shall be  forfeited  to the extent  that a  previously
     granted  Option is  exercised,  or except that its issuance is  conditioned
     upon the termination of a previously granted Option.

     7.2 No Tandem  Options.  Where an Option granted under the Plan is intended
to be an Incentive Stock Option,  the Option shall not contain terms pursuant to
which the exercise of the Option would affect the  Optionee's  right to exercise
another Option,  or vice versa, such that the Option intended to be an Incentive
Stock Option  would be deemed a tandem  stock  option  within the meaning of the
regulations under Section 422 of the Code.

     7.3  Option  Agreement;  Terms and  Conditions  to Apply  Unless  Otherwise
Specified. As determined by the Board on the date of grant, each Option shall be
evidenced by an Option  agreement  (the "Option  Agreement")  that  includes the
non-transferability   provisions   required  by  Section 10.2  hereof  and  that
specifies: the Option price; the duration of the Option; the number of shares of
Stock to which the Option applies;  such vesting or exercisability  restrictions
which the Board may impose; a provision  implementing  the $100,000  Limitation;
and any other terms or conditions which the Board may impose. All such terms and
conditions shall be determined by the Board at the time of grant of the Option.

          (a) If not otherwise  specified by the Board,  the following terms and
     conditions shall apply to Options granted under the Plan:

               (i) Term.  The duration of the Option shall be for ten years from
          the date of grant.

               (ii)  Exercise  of  Option.  Unless an Option  is  terminated  as
          provided  hereunder,  an Optionee may exercise an Option pursuant to a
          vesting schedule as determined by the Board.

                                      -5B-


               (iii) Termination. Each Option granted pursuant to the Plan shall
          expire upon the earliest to occur of:

                    (A) The date set forth in such  Option,  not to  exceed  ten
               years  from  the  date of  grant  (five  years  in the  case of a
               Significant Shareholder);

                    (B) The  completion  of the merger or sale of  substantially
               all of the  Stock or  assets of the  Company  with or to  another
               company  in a  transaction  in  which  the  Company  is  not  the
               survivor,   except  for  the  merger  of  the   Company   into  a
               wholly-owned subsidiary and, provided that the Company shall have
               given the Optionee at least thirty days' prior written  notice of
               its  intent to enter  into such  merger or sale (and the  Company
               shall not be considered  the surviving  corporation  for purposes
               hereof if the  Company is the  survivor  of a reverse  triangular
               merger);

                    (C) Ninety days following the  termination of the employment
               of an Optionee,  except for  termination for cause by the Company
               or termination  because of the Optionee's death or disability (in
               which event of  termination  of employment  due to the Optionee's
               death or  disibility,  the Option shall expire one year following
               the termination of employment of an Optionee); or
                                   
                    (D) Immediately upon the termination of the employment of an
               Optionee for cause by the Company.

               (iv) Nontransferability. All Options granted under the Plan shall
          be nontransferable by the Optionee,  other than by will or the laws of
          descent  and  distribution,   and  shall  be  exercisable  during  the
          Optionee's lifetime only by the Optionee.

          (b) The Board shall be free to specify terms and conditions other than
     and in addition to those set forth above, in its discretion.

          (c) All Option Agreements shall incorporate the provisions of the Plan
     by reference.

     7.4 Option  Price.  No Option  granted  pursuant  to the Plan shall have an
Option  price that is less than the Fair  Market  Value of Stock on the date the
Option is granted.  Incentive Stock Options granted to Significant  Shareholders
shall  have an Option  price of not less than 110% of the Fair  Market  Value of
Stock on the date of grant.  The  Option  exercise  price  shall be  subject  to
adjustment as provided in Section 5.3 above.

     7.5 Payment. Payment for all shares of Stock shall be made at the time that
an Option,  or any part  thereof,  is  exercised,  and no shares shall be issued
until full payment therefor has been made. Payment shall be made (i) in cash, or
(ii) if  acceptable  to the  Board,  in Stock or in some other  form;  provided,
however,  in the case of an  Incentive  Stock  Option,  that such  other form of
payment  does not  prevent  the  Option  from  qualifying  for  treatment  as an
"incentive stock option" within the meaning of the Code.

                                      -6B-


                                  ARTICLE VIII
                        WRITTEN NOTICE, ISSUANCE OF STOCK
                      CERTIFICATES, SHAREHOLDER PRIVILEGES

     8.1 Written  Notice.  An Optionee  wishing to exercise an Option shall give
written notice to the Company,  in the form and manner  prescribed by the Board.
Full payment for the shares of Stock to be acquired  pursuant to the exercise of
the Option must accompany the written notice.

     8.2  Issuance  of Stock  Certificates.  As soon as  practicable  after  the
receipt of written notice and payment, the Company shall deliver to the Optionee
a certificate or certificates for the requisite number of shares of Stock.

     8.3 Privileges of a Shareholder.  An Optionee or any other person  entitled
to  exercise an Option  under the Option  Agreement  shall not have  shareholder

                                   ARTICLE IX
                      TERMINATION OF EMPLOYMENT OR SERVICES

     9.1 Death or  Disability.  Subject  to any prior  partial  exercise  of the
Option, if an Optionee's  employment terminates by reason of Optionee's death or
permanent  and total  disability,  the Option may be exercised up to one hundred
percent of the shares originally  subject to the Option at any time prior to the
expiration  date of the Option or within 12 months  after the date of such death
or  disability,  whichever  period is the  shorter,  by the  person  or  persons
entitled to do so under the  Optionee's  will or, if the Optionee  shall fail to
make a  testamentary  disposition  of an  Option  or shall  die  intestate,  the
Optionee's legal representative or representatives.

     9.2  Termination  other than for Cause or Due to Death.  In the event of an
Optionee's  termination of employment other than by reason of death or permanent
and total  disability,  the Optionee may exercise  such portion of his Option as
was  vested  and  exercisable  by him at  the  date  of  such  termination  (the
"Termination  Date") at any time within ninety days of the Termination  Date. In
any event,  the Option cannot be exercised  after the  expiration of the term of
the Option.  Options not exercised within the applicable  period specified above
shall terminate.

     (a) In the case of an Employee,  a change of duties or position  within the
Company or an assignment of  employment  in a Subsidiary  Corporation  or Parent
Corporation  of the Company,  if any, or from such a Corporation to the Company,
shall not be considered a termination of employment for purposes of the Plan.

                                      -7B-


     (b) The Option  Agreements  may contain such  provisions as the Board shall
approve  with  reference  to the  effect  of  approved  leaves of  absence  upon
termination of employment.

     9.3  Termination  for Cause.  In the event of an Optionee's  termination of
employment,  which termination is by the Company or a Subsidiary Corporation for
cause,  any  Option or  Options  held by him under the Plan,  to the  extent not
exercised  before such  termination,  shall terminate upon notice of termination
for cause. 

                                    ARTICLE X
                              RIGHTS OF OPTIONEES

     10.1 Service.  Nothing in the Plan shall interfere with or limit in any way
the right of the Company or a Subsidiary Corporation to terminate any Employee's
employment  at any time,  nor confer upon any  Employee any right to continue in
the employ of the Company or a Subsidiary Corporation.

     10.2  Non-transferability.  All  Options  granted  under the Plan  shall be
nontransferable  by the Optionee,  other than by will or the laws of descent and
distribution,  and shall be exercisable  during the Optionee's  lifetime only by
the Optionee.

                                   ARTICLE XI
                          OPTIONEE-EMPLOYEE'S TRANSFER

          (b) A  leave  of  absence  for  such  an  Optionee  (i) which  is duly
     authorized  in writing  by the  Company or a  Subsidiary  Corporation,  and
     (ii) if the Optionee holds an Incentive Stock Option, which qualifies under
     the  applicable  regulations  under  the  Code  which  apply in the case of
     incentive stock options,

shall not be deemed a termination of employment. However, under no circumstances
may an  Optionee  exercise  an  Option  during  any  leave  of  absence,  unless
authorized by the Board.

                          AMENDMENT, MODIFICATION, AND
                             TERMINATION OF THE PLAN

          (a) The  Board  may at any time  terminate  and from  time to time may
     amend or modify the Plan,  provided,  however,  that no such  action of the
     Board, without approval of the shareholders, may:

               (i)  increase  the total  amount of Stock which may be  purchased
          through  Options  granted  under  the  Plan,  except  as  provided  in
          Article V;

               (ii) change the class of Employees eligible to receive Options;

     Company,  the Company  shall have the option,  but not the  obligation,  to
     cancel Options  outstanding  as of the effective date of such  acquisition,
     whether or not such Options are then exercisable,  in return for payment to
     the  Optionees  of an amount  equal to a  reasonable  estimate of an amount
     (hereinafter  the  "Spread"),   determined  by  the  Board,  equal  to  the
     difference  between the net amount per share payable in the  acquisition or
     as a result of the acquisition,  less the exercise price of the Option.  In
     estimating  the  Spread,  appropriate  adjustments  to give  effect  to the
     existence of the Options shall be made, such as deeming the Options to have
     been  exercised,  with the Company  receiving  the exercise  price  payable
     thereunder, and treating the shares receivable upon exercise of the Options
     as being outstanding in determining the net amount per share.

          (b) For  purposes of this  section,  an  "acquisition"  shall mean any
     transaction in which substantially all of the Company's assets are acquired
     or in which a controlling  amount of the Company's  outstanding  shares are
     acquired,  in each case by a single person or entity or an affiliated group
     of persons and entities. For purposes of this section, a controlling amount
     shall mean more than 50% of the issued and  outstanding  shares of Stock of
     the  Company.  The Company  shall have the above  option to cancel  Options
     regardless  of how  the  acquisition  is  effectuated,  whether  by  direct
     purchase, through a merger or similar corporate transaction,  or otherwise.
     In cases where the acquisition consists of the acquisition of assets of the
     Company,  the net amount per share shall be  calculated on the basis of the
     net amount  receivable  with  respect  to shares  upon a  distribution  and
     liquidation  by the Company  after  giving  effect to expenses and charges,
     including  but not  limited  to taxes,  payable by the  Company  before the
     liquidation can be completed.

          (c)  Where  the  Company  does not  exercise  its  option  under  this
     Section 13.1 the remaining  provisions of this Article XIII shall apply, to
     the extent applicable.

                                      -9B-


     13.2  Merger  or  Consolidation.  If the  Company  shall  be the  surviving
corporation in any merger or  consolidation,  any Option granted hereunder shall
pertain to and apply to the securities to which a holder of the number of shares
of Stock  subject  to the  Option  would have been  entitled  in such  merger or
consolidation,  provided that the Company shall not be considered  the surviving
corporation  for  purposes  hereof if the  Company is the  survivor of a reverse
triangular merger.

     13.3 Other Transactions. A dissolution or a liquidation of the Company or a
merger and  consolidation in which the Company is not the surviving  corporation
(the Company shall not be  considered  the  surviving  corporation  for purposes
hereof if the Company is the  survivor  of a reverse  triangular  merger)  shall
cause every Option  outstanding  hereunder to terminate as of the effective date
of such dissolution, liquidation, merger or consolidation. However, the Optionee
either (i) shall be offered a firm commitment whereby the resulting or surviving
corporation in a merger or  consolidation  will tender to the Optionee an option
(the "Substitute Option") to purchase its shares on terms and conditions both as
to number of shares and  otherwise,  which will  substantially  preserve  to the
Optionee the rights and benefits of the Option outstanding  hereunder granted by
the Company, or (ii) shall have the right immediately prior to such dissolution,
liquidation,  merger,  or  consolidation  to exercise  any  unexercised  Options
whether or not then vested,  subject to the  provisions  of the Plan.  The Board
shall have  absolute  and  uncontrolled  discretion  to  determine  whether  the
Optionee has been offered a firm commitment and whether the tendered  Substitute
Option will  substantially  preserve to the  Optionee the rights and benefits of
the Option  outstanding  hereunder.  In any event, any Substitute  Option for an
Incentive   Stock   Option   shall   comply  with  the   requirements   of  Code
Section 424(a).

                                   ARTICLE XIV
                             SECURITIES REGISTRATION

     14.1 Securities  Registration.  In the event that the Company shall deem it
necessary or desirable to register under the Securities Act of 1933, as amended,
or any other applicable statute,  any Options or any Stock with respect to which
an Option may be or shall have been granted or exercised, or to qualify any such
Options or Stock under the  Securities  Act of 1933,  as  amended,  or any other
statute, then the Optionee shall cooperate with the Company and take such action
as is  necessary  to permit  registration  or  qualification  of such Options or
Stock.

     14.2 Representations.  Unless the Company has determined that the following
representation  is unnecessary,  each person exercising an Option under the Plan
may be required by the  Company,  as a condition  to the  issuance of the shares
pursuant to exercise of the Option, to make a representation in writing (i) that
he is acquiring  such shares for his own account for  investment  and not with a
view to, or for sale in connection  with, the  distribution  of any part thereof
within the meaning of the Securities Act of 1933,  (ii) that before any transfer
in connection with the resale of such shares, he will obtain the written opinion
of counsel for the Company,  or other counsel  acceptable  to the Company,  that
such shares may be transferred  without  registration  thereof.  The Company may
also require that the  certificates  representing  such shares  contain  legends
reflecting  the  foregoing.  To the  extent  permitted  by  law,  including  the
Securities  Act of 1933,  nothing  herein  shall  restrict the right of a person
exercising an Option to sell the shares received in an open market transaction.

                                   ARTICLE XV
                                 TAX WITHHOLDING

     Whenever  shares  of Stock  are to be issued  in  satisfaction  of  Options
exercised  under the Plan,  the  Company  shall  have the power to  require  the
recipient of the Stock to remit to the Company an amount  sufficient  to satisfy
federal, state, and local withholding tax requirements, if any.

                                   ARTICLE XVI
                                 INDEMNIFICATION

     To the extent  permitted  by law,  each  person who is or shall have been a
member of the Board or the Committee  shall be indemnified  and held harmless by
the Company against and from any loss, cost,  liability,  or expense that may be
imposed upon or reasonably  incurred by him in connection with or resulting from
any claim, action, suit, or proceeding to which he may be a party or in which he
may be involved  by reason of any action  taken or failure to act under the Plan
and against and from any and all amounts paid by him in settlement thereof, with
the Company's  approval,  or paid by him in satisfaction of judgment in any such
action,  suit, or proceeding  against him, provided he shall give the Company an
opportunity,  at its own  expense,  to  handle  and  defend  the same  before he
undertakes  to handle and defend it on his own behalf.  The  foregoing  right of
indemnification shall not be exclusive of any other rights of indemnification to
which  such  persons  may  be  entitled  under  the  Company's   certificate  of
incorporation or bylaws, as a matter of law, or otherwise, or any power that the
Company or any  Subsidiary  Corporation  may have to indemnify them or hold them
harmless.

                                  ARTICLE XVII
                               REQUIREMENTS OF LAW

     17.1  Requirements  of Law.  The  granting of Options  and the  issuance of
shares  of  Stock  upon the  exercise  of an  Option  shall  be  subject  to all
applicable  laws,  rules,  and  regulations,   and  to  such  approvals  by  any
governmental agencies or national securities exchanges as may be required.

     17.2  Governing  Law.  The Plan,  and all  agreements  hereunder,  shall be
construed in accordance with and governed by the laws of the State of Colorado.

                                  ARTICLE XVIII
                             EFFECTIVE DATE OF PLAN

     The Plan shall be effective on March 27, 1997.

                                   ARTICLE XIX
                              COMPLIANCE WITH CODE

     Incentive  Stock  Options  granted  hereunder  are  intended  to qualify as
"incentive  stock  options" under Code Section 422. If any provision of the Plan
is susceptible to more than one  interpretation,  such  interpretation  shall be
given thereto as is consistent  with Incentive  Stock Options  granted under the
Plan being treated as incentive stock options under the Code.

                                     -11B-


                                   ARTICLE XX
                        NO OBLIGATION TO EXERCISE OPTION

     The  granting  of an Option  shall  impose no  obligation  upon the  holder
thereof to exercise such Option.

                                   ARTICLE XXI
                              SHAREHOLDER APPROVAL

     The Plan shall be submitted for approval and  ratification by a vote of the
holders  of a majority  of the  shares of Stock of the  Company no later than 12
months after the date the Plan is adopted;  provided,  however,  that failure to
timely  obtain such  shareholder  approval  shall result in all Options  granted
hereunder  being  deemed to be  Non-qualified  Options  and shall not affect the
validity of any Option issued under the Plan.

     THIS  INCENTIVE  STOCK OPTION PLAN was adopted by the Board of Directors of
St. Mary Land &  Exploration  Company on March 27,  1997,  to be effective  upon
adoption.
