                         FORM OF STOCK OPTION AGREEMENT

         This Stock Option Agreement (this "Agreement"), is dated as of July 31,
1997 by and between Snyder Oil Corporation,  a Delaware corporation ("SOCO") and
the  other  person  whose  signature   appears  on  the  signature  page  hereof
("Optionee").

         WHEREAS,  SOCO owns  beneficially and of record  14,000,000 shares (the
"SOCO Shares") of Common Stock of Patina  ("Common  Stock"),  2,000,000 of which
are designated Series A Common Stock;

         WHEREAS,   concurrently   with  the  execution  and  delivery  of  this
Agreement, Optionee and certain other persons have entered into a Stock Purchase
Agreement  (the  "Stock  Purchase  Agreement")  with  Patina,  pursuant to which
Optionee  and  such  other  persons  have  agreed  to  acquire  shares  of  8.5%
Convertible  Preferred Stock (the "New Preferred Stock"), of Patina on the terms
and subject to the conditions set forth therein;

         WHEREAS,  as a condition to  Optionee's  willingness  to enter into the
Stock Purchase  Agreement,  Optionee has requested that SOCO agree, and SOCO has
so agreed,  to grant to Optionee an option with respect to certain shares of the
Common Stock, on the terms and subject to the conditions set forth herein;

         WHEREAS,   concurrently   with  the  execution  and  delivery  of  this
Agreement, SOCO (i) has granted options to the other purchasers of New Preferred
Stock under  comparable  option  agreements,  which options  (together  with the
option under this  Agreement)  cover an aggregate of 2,000,000  shares of Common
Stock and (ii) has granted  options to Thomas J. Edelman  under  similar  option
agreements,  which  options  cover an aggregate  of  2,000,000  shares of Common
Stock;

         WHEREAS,  SOCO has given Patina notice of its current intention to sell
a portion of the shares of Common  Stock owned by it in an  underwritten  public
offering (the "Offering");

         WHEREAS,   concurrently   with  the  execution  and  delivery  of  this
Agreement,  SOCO and  Patina  have  entered  into a Share  Repurchase  Agreement
pursuant to which Patina has agreed, among other things, to repurchase from SOCO
all shares of Common Stock owned by SOCO at the time of the  consummation of the
Offering  that  are  not  sold by SOCO to the  underwriters  at such  time  (the
"Repurchase");

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

         1.  Grant of Option.  SOCO hereby grants Optionee an irrevocable option
(the "Option") to purchase from SOCO the number of shares of Common Stock set
forth for Optionee on the signature page hereof, subject to adjustment as
provided in Section 8 hereof (such shares being

                                        1


referred to herein as the  "Option  Shares") in the manner set forth below at an
exercise  price of $8.00 per Company Share (the  "Exercise  Price"),  payable in
cash in accordance with Section 4 hereof.

         2.       Exercise of Option.

         (a)The following terms shall have the following respective definitions:

                  (i) The term "Applicable Percentage" shall mean (A) the number
         of Option Shares on the date hereof divided by (B) 2,000,000.

                  (ii) The term  "Applicable  Sharing  Threshold" shall mean (A)
         $2,500,000 multiplied by (B) the Applicable Percentage.

                  (iii) "Sale  Transaction" shall mean an acquisition (by tender
         offer,  exchange  offer,  merger,  consolidation,   share  exchange  or
         otherwise)  by a third  party of Patina  (or its  shares or  assets) in
         which such third party  acquires,  directly or  indirectly,  at least a
         majority  of the assets or  combined  voting  power of the  outstanding
         capital stock of Patina.

                  (iv)  "Qualifying   Termination  Event"  shall  mean  (y)  the
         termination of the Stock Purchase  Agreement as a result of the failure
         of the  conditions  set forth in  Section  5.04  thereof,  preceded  or
         followed  within  20  business  days by the  sale  by SOCO of at  least
         12,000,000 shares of Common Stock whether in the Offering,  pursuant to
         the Share  Repurchase  Agreement or otherwise or (z) the  withdrawal of
         Shares  from  the  Offering  by SOCO or the  termination  of the  Share
         Repurchase Agreement by SOCO other than because of (A) a failure of any
         of the  conditions  set forth in  Sections  3(b)(i) or  3(b)(ii) of the
         Share Repurchase Agreement,  (B) a failure of any of the conditions set
         forth  in  Sections  3(b)(iii)  or  3(b)(iv)  of the  Share  Repurchase
         Agreement  other  than as a direct  result of a failure  by SOCO to use
         commercially reasonable efforts in connection with the Offering to take
         such  actions  as are  customarily  required  to be taken by a  selling
         stockholder  in an offering  such as the Offering  (provided,  however,
         that SOCO may,  subject to  compliance  with  Section 6(c) of the Share
         Repurchase Agreement,  continue to pursue, but not consummate, the sale
         of all or part of its  Shares  to one or  more  prospective  purchasers
         without  being deemed to fail to use such  efforts) or (C) a failure of
         the  condition  set forth in Section  3(a)(ii) of the Share  Repurchase
         Agreement  as a  result  of  the  termination  of  the  Stock  Purchase
         Agreement by any party thereto.

                  (v)      The term "Spread" shall mean:

                           (A)      the excess, if any, of

                                    (1) the  "Offer  Price" for shares of Common
                           Stock  as of the date  Optionee  gives  the  Exercise
                           Notice  under  Section  2(e) or Section  2(f)  hereof
                           (defined as the highest  price per share  offered for
                           all shares of Common

                                        2


                           Stock  for  which an  offer  is made as of such  date
                           pursuant  to  the  Sale  Transaction  that  has  been
                           announced  prior  to such  date and that has not been
                           terminated  or withdrawn  as of such date;  provided,
                           however,  that in the event that the Sale Transaction
                           is structured  primarily as an asset sale,  the Offer
                           Price shall be equal to the average  closing price on
                           the New York Stock Exchange for the Common Stock over
                           a period of 10  consecutive  New York Stock  Exchange
                           trading  days  ("Trading  Day")  ending  on the third
                           Trading  Day  prior  to  the  closing  of  such  Sale
                           Transaction); over

                                    (2) the Exercise Price,

                           multiplied by

                           (B) the number of Option Shares purchasable  pursuant
                           to the Option, but only if the Offer Price is greater
                           than the Exercise Price.

                  (vi) The term "Put  Price"  shall  mean the  greater of (A) $2
         million multiplied by the Applicable Percentage and (B) the Spread.

         (b) The Option may be exercised by Optionee,  in whole but not in part,
at any time after a Qualifying  Termination  Event and prior to the  termination
hereof.

         (c) The  Option  shall  terminate  upon the  earliest  to occur of: (i)
consummation  of the Offering and the  Repurchase in  accordance  with the Share
Repurchase  Agreement,  (ii) the withdrawal of the SOCO Shares from the Offering
or the termination of the Share Repurchase Agreement, in each case other than as
a  result  of  a  Qualifying  Termination  Event;  (iii)  five  days  after  the
consummation of a Sale  Transaction,  (iv) 11 business days after the occurrence
of a Qualifying  Termination Event specified in Section  2(a)(iv)(y) and (v) the
expiration  of 12 months  following  any  termination  of the  Share  Repurchase
Agreement  or  withdrawal  of shares from the Offering  (whichever  is earlier);
provided,  however,  that with  respect  to any Sale  Transaction  involving  an
acquiror that does not visit  Patina's data room after July 1, 1997 and prior to
the Distribution Date (as defined in the Share Repurchase Agreement), the Option
may not be exercised  after six months  following any  termination  of the Share
Repurchase  Agreement or  withdrawal  of shares from the Offering  (whichever is
earlier).  Notwithstanding  the  foregoing,  the Option may not be  exercised by
Optionee if Optionee (or any of its  affiliates) is in material breach of any of
its material representations or warranties,  or in material breach of any of its
covenants or  agreements,  contained in this  Agreement or in the Stock Purchase
Agreement.

         (d) SOCO  agrees  to  notify  Optionee  promptly  in  writing  if (i) a
Qualifying  Termination  Event  occurs,  (ii) a definitive  agreement for a Sale
Transaction  has been executed,  or (iii) a Sale  Transaction  has been publicly
announced,  it being understood that the giving of such notice by SOCO shall not
be a condition to the right of Optionee to exercise the Option.


                                        3


         (e) If Optionee  wishes to exercise the Option,  Optionee shall deliver
to SOCO a written notice (an "Exercise Notice")  specifying that Optionee wishes
to exercise  the Option,  which  notice  shall be delivered to SOCO prior to the

termination  of the  Option.  The  closing  of a  purchase  of Option  Shares (a
"Closing")  shall  occur on the fifth  business  day  following  the date of the
Optionee's  Exercise  Notice  at  SOCO's  principal  executive  offices,  unless
otherwise  agreed  by SOCO  and the  Optionee;  provided,  however,  that if the
Optionee elects to exercise the Optionee Put described  below, the Closing shall
be  subject  to,  and shall not occur  earlier  than  simultaneously  with,  the
consummation  of the applicable  Sale  Transaction;  provided  further that if a
Qualifying  Termination  Event  specified  in Section  2(a)(iv)(y)  occurs,  the
Closing  shall be subject to, and shall not occur  earlier  than  simultaneously
with the sale by SOCO of the  12,000,000  shares of Common Stock  referred to in
such section.

         (f) If the Optionee's  exercise of the Option relates to the occurrence
of a Qualifying  Termination Event specified in Section 2(a)(iv)(z),  in lieu of
purchasing shares upon exercise of the Option,  Optionee may elect to cause SOCO
to  repurchase  the Option at the Closing  (the  "Optionee  Put") for a purchase
price equal to the Put Price.  In order to be effective,  each  Exercise  Notice
shall  specify  Optionee's  election to either (i) purchase the shares of Common
Stock covered by such Exercise Notice or (ii) cause the Option to be repurchased
by SOCO pursuant to the Optionee Put.

         (g)  Notwithstanding  the foregoing,  if the Optionee's exercise of the
Option relates to the occurrence of a Qualifying  Termination Event specified in
Section 2(a)(iv)(z),  and if the Put Price for the Option exceeds the Applicable
Sharing Threshold, then the Put Price shall be reduced by, or the exercise price
shall be  increased  by, as  applicable,  an  amount  in cash  equal to (i) 50%,
multiplied by (ii) the excess of the Put Price (prior to such  adjustment)  over
the Applicable Sharing Threshold.

         (h) If Optionee  exercises  the  Optionee  Put pursuant to Section 2(f)
hereof,  SOCO  shall at the  Closing  pay the  required  amount to  Optionee  in
immediately available funds and Optionee shall surrender to SOCO the Option, and
Optionee  shall  warrant  that it owns the  Option  free and clear of all liens,
claims, damages, charges and encumbrances of any kind or nature whatsoever.

         3. Conditions to Closing. The obligation of SOCO to transfer the Option
Shares to Optionee hereunder is subject to the conditions that no preliminary or
permanent  injunction  or other  order by any  court of  competent  jurisdiction
prohibiting or otherwise restraining such issuance shall be in effect; provided,
however, that the Optionee shall be afforded the opportunity, by notice to SOCO,
to postpone the Closing for a reasonable  period of time,  not to exceed 30 days
after the date of the Exercise Notice, to enable the appropriate  parties to use
commercially  reasonable  efforts to respond to, or remove,  such  impediment to
Closing.

         4. Closing.  At any Closing at which the Optionee Put is not exercised,
(a) SOCO will  deliver to Optionee  (or its  designee) a single  certificate  in
definitive  form  representing  the number of the Option  Shares  designated  by
Optionee in its Exercise  Notice,  such certificate to be registered in the name
of  Optionee  and to bear the  legend  set  forth in  Section  9 hereof  and (b)
Optionee  will  deliver to SOCO the  aggregate  price for the  Option  Shares so
designated and being purchased by

                                        4


wire transfer of immediately  available  funds or certified check or bank check.
SOCO shall pay all expenses,  and any and all United States  federal,  state and
local  taxes  and other  charges  that may be  payable  in  connection  with the
preparation,  issue and  delivery  of stock  certificates  under this  Section 4
hereof in the name of Optionee or its designee.

         5. Representations and Warranties of SOCO. SOCO represents and warrants
to Optionee  that (a) upon  delivery of the Option  Shares to Optionee  upon the
exercise of the Option,  Optionee  will acquire the Option Shares free and clear
of all claims, liens, charges, encumbrances and security interests of any nature
whatsoever,  (b) none of SOCO,  any of its affiliates or anyone acting on its or
their  behalf has issued,  sold or offered any  security of Patina to any person
under  circumstances,  or taken any other action,  that would cause the sale and
transfer of the Option Shares, as contemplated by this Agreement,  to be subject
to the registration  requirements of the Securities Act of 1933, as amended (the
"Securities   Act"),  as  in  effect  on  the  date  hereof  and,  assuming  the
representations  of Optionee contained in Section 6 hereof are true and correct,
the issuance,  sale and delivery of the Option Shares hereunder upon exercise of
the  Option  will be  exempt  from  the  registration  and  prospectus  delivery
requirements  of the Securities Act, as in effect on the date hereof and (c) the
execution  and  delivery  of  this  Agreement  and  the   consummation   of  the
transactions  contemplated herein do not, and will not, conflict with or violate
any terms of any contract, note, instrument,  indenture, agreement,  certificate
of incorporation,  bylaws,  law, rule,  regulation or restriction  applicable to
SOCO or its affiliates (other than Patina).

         6. Representations and Warranties of Optionee.  Optionee represents and
warrants to SOCO that any Option  Shares  acquired  upon  exercise of the Option
will be acquired for Optionee's own account,  and will not be, and the Option is
not being,  acquired  by  Optionee  with a view to the  distribution  thereof in
violation of any applicable provision of the Securities Act.

         7. No Rights as Stockholder.  No holder of the Option shall be, or have
any of the rights or privileges  of, a  stockholder  of Patina in respect of any
shares  subject to the Option  unless and until such  holder's  exercise  of the
Option (but not  including an exercise of the Optionee  Put) is  consummated  in
accordance with the provisions of this  Agreement.  The decision to proceed with
the Offering,  the  Repurchase or any other  transaction  relating to Patina (as
well as the terms of any such transaction)  shall, as between SOCO and Optionee,
be in the absolute and sole  discretion of SOCO,  and nothing in this  Agreement
shall create any  fiduciary  or other  duties from SOCO to Optionee,  except for
those contractual obligations expressly set forth herein.

         8.  Adjustment  Upon Changes in  Capitalization.  Without  limiting any
restriction on SOCO contained in this  Agreement,  in the event of any change in
Common Stock by reason of stock dividends, splitups, mergers, recapitalizations,
combinations,  exchange of shares or the like,  the type and number of shares or
securities  subject to the Option,  and the purchase price per share provided in
Section  1  hereof,  as well as the type and  number  of  shares  or  securities
referred to in Sections 2(a)(iv)(y) and 2(e), shall be adjusted appropriately to
restore to Optionee its rights hereunder.


                                        5


         9.Restrictive Legends.  Each certificate representing shares of Common
Stock issued to Optionee hereunder shall include a legend in substantially 
the following form:

                  THE SECURITIES  REPRESENTED BY THIS  CERTIFICATE HAVE NOT BEEN
         REGISTERED  UNDER THE  SECURITIES  ACT OF 1933, AS AMENDED,  AND MAY BE
         REOFFERED OR SOLD ONLY IF SO  REGISTERED  OR IF AN EXEMPTION  FROM SUCH
         REGISTRATION  IS  AVAILABLE.   SUCH  SECURITIES  ARE  ALSO  SUBJECT  TO
         ADDITIONAL  RESTRICTIONS  ON TRANSFER AS SET FORTH IN THE STOCK  OPTION
         AGREEMENT,  DATED AS OF JULY 31,  1997, A COPY OF WHICH MAY BE OBTAINED
         FROM THE ISSUER UPON REQUEST.

It is understood and agreed that:  (i) the reference to the resale  restrictions
of the  Securities  Act in the above  legend  shall be  removed by  delivery  of
substitute   certificate(s)  without  such  reference  if  Optionee  shall  have
delivered  to SOCO a copy of a letter  from  the  staff  of the  Securities  and
Exchange   Commission,   or  an  opinion  of  counsel,  in  form  and  substance
satisfactory  to SOCO,  to the  effect  that  such  legend is not  required  for
purposes of the  Securities  Act; (ii) the  reference to the  provisions to this
Agreement  in the above  legend  shall be  removed  by  delivery  of  substitute
certificate(s)   without  such  reference  if  the  shares  have  been  sold  or
transferred  in  compliance  with the  provisions  of this  Agreement  and under
circumstances that do not require the retention of such reference; and (iii) the
legend  shall be removed in its  entirety  if the  conditions  in the  preceding
clauses (i) and (ii) are both satisfied.  In addition,  such certificates  shall
bear any other legend as may be required by law.

         10. Binding Effect; No Assignment;  No Third Party Beneficiaries.  This
Agreement  shall be binding upon and inure to the benefit of the parties  hereto
and their  respective  successors  and  permitted  assigns.  Except as expressly
provided for in this  Agreement,  neither this  Agreement  nor the rights or the
obligations of either party hereto are  assignable,  except by operation of law,
or with the  written  consent of the other  party,  which  consent  shall not be
unreasonably withheld. Nothing contained in this Agreement,  express or implied,
is intended to confer  upon any person  other than the parties  hereto and their
respective  permitted assigns any rights or remedies of any nature whatsoever by
reason of this Agreement.

         11. Specific Performance. The parties hereby acknowledge and agree that
the failure of SOCO to perform its agreement and covenants  hereunder will cause
irreparable injury to Optionee for which damages, even if available, will not be
an  adequate  remedy.  Accordingly,  SOCO  hereby  consents  to the  issuance of
injunctive relief by any court of competent  jurisdiction to compel  performance
of SOCO's  obligations  and to the  granting  by any such court of the remedy of
specific performance of its obligations hereunder.

         12.Further Assurances.  Each party will execute and deliver all such 
further documents and instruments and take all such further action as may be 
necessary in order to consummate the transactions contemplated hereby.

                                        6


         13. Validity.  The invalidity or  unenforceability  of any provision of
this  Agreement  shall not affect the  validity or  enforceability  of the other
provisions of this  Agreement,  which shall remain in full force and effect.  If
any court or other competent authority holds any provisions of this Agreement to
be null, void or unenforceable, the parties hereto shall negotiate in good faith
the execution and delivery of an amendment to this Agreement in order, as nearly
as possible,  to effectuate,  to the extent  permitted by law, the intent of the
parties hereto with respect to such provision and the economic  effects thereof.
Each party agrees that,  should any court or other competent  authority hold any
provision of this Agreement or part hereof to be null, void or unenforceable, or
order any party to take any action inconsistent herewith, or not take any action
required herein,  the other party shall not be entitled to specific  performance
of such  provision  or part  hereof or to any other  remedy,  including  without
limitation  money damages,  for breach hereof or of any other  provision of this
Agreement or part hereof as the result of such holding or order.

federal laws to apply (rather than arbitration  rules),  the parties desire that
their disputes be resolved by a judge applying such applicable laws.  Therefore,
to achieve the best  combination  of the benefits of the judicial  system and of
arbitration,  the parties hereto waive all right to trial by jury in any action,
suit or  proceeding  brought to enforce or defend any rights or  remedies  under
this Agreement.

     20.  Extension  of Time  Periods.  The time periods for exercise of certain
rights  under  Sections  2 and 4 hereof  shall  be  extended  (a) to the  extent
necessary to obtain all  regulatory  approvals  for the exercise of such rights,
and for the  expiration of all statutory  waiting  periods and (b) to the extent
necessary to avoid any liability under Section 16(b) of the Securities  Exchange
Act of 1934, as amended, by reason of such exercise.

     21.  References  to Other  Agreements.  To the extent  that this  Agreement
refers to any other agreement, or any provision thereof, such reference shall be
deemed to be to such  agreement or provision in the form  initially  executed by
the parties  thereto  (regardless  of whether  such  agreement  or  provision is
amended)  unless and to the extent that (a) such  amendment  does not  adversely
affect the non-signing party or (b) the non-signing party consents in writing to
such amendment.
