AGREEMENT

      THIS  AGREEMENT is made and entered into this 16th day of July,  1996, but
effective on July 31, 1996, by and between F.H. Smith  (Employee) and Patina Oil
& Gas Corporation ("Patina or the Company").

                                    RECITALS

1.    Employee is employed by Patina as a Vice President of Operations.

2. Employee's employment with Patina commenced on May 2, 1996 as a result of the
closing of the  transactions  contemplated by an amended and restated  Agreement
and Plan of Merger  dated as of January 16, 1996 and amended and  restated as of
March  20,  1996  by  and  among  Snyder  Oil  Corporation,  Patina  Oil  &  Gas
Corporation,  Patina Merger  Corporation and Gerrity Oil & Gas Corporation  (the
"Merger").

3. As a result of the Merger,  Patina  determined that certain positions held by
former Snyder Oil  Corporation  employees and former Gerrity Oil & Gas employees
were no longer necessary and certain  employees were laid off as a result of the
Merger.  Employee's position initially was not one identified as being no longer
necessary as a consequence of the Merger.

4.  While  Employee's  position  was  not  initially  identified  as  one  to be
eliminated  as a  result  of the  Merger,  it has now been  identified  as being
duplicative and no longer necessary for the ongoing operations of Patina.

5. As a result,  Employee  and Patina have  agreed to enter into this  Agreement
pursuant  to which  Employee  is being laid off as a direct  consequence  of the
Merger.

                                    AGREEMENT

      In  consideration  of a payment by Patina to  Employee  of the amounts set
forth herein, and in further  consideration of the mutual covenants,  conditions
and  stipulations  set  forth in this  Agreement,  Employee  and  Patina  agree,
effective as provided in paragraph 7 as follows:

1.  Employee's  employment  with  Patina  will  terminate  effective  5:00 p.m.,
Mountain  Daylight Time, July 31, 1996. On July 31, 1996,  Employee will be paid
his regular salary for July 1996, subject to normal and standard  deductions for
FICA,  Medicare,  tax, state and federal taxes, all as applicable.  In addition,
Employee will be paid the sum of $75,000 (subject to applicable withholdings and
deductions,  if any) as a severance allowance. In addition, as of July 31, 1996,
Employee  will have  accrued  20.75 days of vacation  for which he will be paid.
Employee may purchase from Patina, the Company vehicle he currently is utilizing
for Company  business  if Patina and  Employee  agree on a purchase  price on or
before July 25, 1996. If Employee purchases the vehicle,  the purchase price for
the vehicle will be deducted  from  Employee's  severance  allowance and accrued
vacation payment. If Employee purchases the vehicle,  clear title to the vehicle
will be delivered to Employee on July 31, 1996.



2. In consideration of the foregoing, Employee hereby knowingly and voluntarily,
fully and finally releases,  acquits, and forever discharges Patina, Gerrity Oil
& Gas Corporation  and SOCO Wattenberg  Corporation and any affiliates and their
past and  present  officers,  directors,  (in their  capacity  as  officers  and
directors),   stockholders,   partners,   trustees,   beneficiaries,   managers,
employees, attorneys, agents, successors or assigns (collectively,  the "Company
and Related Release  Parties"),  from any and all claims,  charges,  complaints,
liens, demands, causes of action, obligations,  damages and liabilities, whether
known or unknown,  that he had,  now has, or may after claim to have against the
Company and  Related  Release  Parties  arising out of or relating in any way to
Employee's  relationship  with  Patina  and/or its  subsidiaries  as an officer,
director,  employee, or in any other capacity,  except those arising out of this
Agreement  and  Rights  to  Indemnification  under  the  Patina  Certificate  of
Incorporation,  By-Laws and Delaware law and directors and officers insurance as
currently in effect.  This Release  expressly  extends to, without  limiting the
generality  of the  foregoing,  any claims  arising under Title VII of the Civil
Rights  Act of 1964 as  amended,  Age  Discrimination  and  Employment  Act,  as
amended, the United States  Constitution,  any State Constitutions and any other
federal,  state  or  local  statute,   regulation  or  ordinance  governing  the
employment relationship.

5. It is expressly  understood and agreed that there are no claims or provisions
or  liabilities  other  than  those set forth or  otherwise  referenced  in this
Agreement and with respect to the Agreement,  Employee covenants and agrees that
he shall forever refrain from initiating,  prosecuting,  maintaining or pressing
any action,  suit or claim in any  jurisdiction  against the Company and Related
Release  Parties based upon the termination of his employment as a result of the
Merger or holding of any office with the Company and Related  Release Parties or
any of their subsidiaries prior to the effective date hereof.

6. Employee  represents  and warrants that there has been no assignment or other
transfer  of any  interest  in any claim he may have  against  the  Company  and
Related  Release  Parties,  or any of them, and Employee agrees to indemnify and
hold  harmless the Company and Related  Release of Parties and each of them from
any liability,  claims,  demands,  damages,  costs,  expenses and attorneys fees
incurred by any such Company and Released  Parties,  or any of them, as a result
of any such assignment or transfer.

7. Employee  represents and acknowledges  that he is aware that he has the right
to review  this  Agreement,  and  specifically,  the  provisions  regarding  the
release,  with legal  counsel of his choice prior to signing the  Agreement  and
that he has done so. Employee  further  represents and  acknowledges  that he is
aware that he has a 21 day period  within  which to consider the  provisions  of
this Agreement,  although he may sign and return such Agreement sooner,  that he
has the right to revoke the  Agreement  for a period of seven days after signing
it, and that the  Agreement  shall not be  effective or  enforceable  until such
seven day revocation expires without revocation.

8. Employee  represents  that this  Agreement has been carefully read by him and
that he knows  and  understands  the  contents  hereof.  Employee  has  received
independent  legal  advise  from  attorneys  of his choice  with  respect to the
preparation,  review and  advisability  of executing  this  Agreement.  Employee
further represents and acknowledges that he has freely and voluntarily  executed
this Agreement  after  independent  investigation  and without fraud,  duress or
undue influence and that in






executing this Agreement he has not relied on any  representations  or statement
not set forth herein with regard to the subject matter, basis, or effect of this
Agreement or otherwise.

9. This  Agreement  will be governed by and construed in force under the laws of
the State of Colorado without regard to its conflict of laws rules.

10. While the  provisions  contained in this  Agreement  are  considered  by the
parties to be reasonable in all circumstances,  it is recognized that provisions
of the nature in question may fail for technical reasons and, accordingly, it is
hereby  agreed and declared  that if any one or more of such  provisions  shall,
either by itself or themselves or taken with others,  be judged to be invalid as
exceeding  what is reasonable  in all  circumstances  for the  protection of the
interests  of  Patina,  but  would  be  valid  if any  particular  provision  or
provisions were deleted or restricted or limited in any particular  manner or if
the period thereof were reduced or curtailed,  then such provisions  shall apply
with  such  deletion,  restriction,   limitation,   reduction,   curtailment  or
modification as may be necessary to make them valid and effective.

11. This Agreement  constitutes the entire Agreement relating to the matters set
forth herein  between the parties who have executed and  supersedes  any and all
other Agreements, understandings, negotiations, or discussions either oral or in
writing express or implied,  between the parties to this Agreement.  The parties

no  representations,   inducements,   promises,  agreements  or  warranties,  or
otherwise have been made by them or anyone acting on their behalf, which are not
embodied  to this  Agreement,  that they have not  executed  this  Agreement  in
reliance on any such representation,  inducement, promise, agreement or warranty
and that no  representation,  inducement,  promise,  agreement  or warranty  not
contained  in  this  Agreement  including  but not  limited  to,  any  purported
supplements,  modifications,  waivers or terminations of this Agreement shall be
valid  or  binding,  unless  executed  in  writing  by all the  parties  to this
Agreement.
