Item 2.           Acquisition or Disposition of Assets.

         As announced on May 2, 1996, the merger (the "Merger") of Gerrity Oil &
Gas Corporation  ("Gerrity") into a wholly-owned  subsidiary of Patina Oil & Gas
Corporation  ("Patina") occurred on May 2, 1996 following approval of the Merger
by Gerrity's common  shareholders.  As a result of the Merger,  Gerrity became a
wholly-owned  subsidiary of Patina.  Simultaneously with the Merger,  Snyder Oil
Corporation  ("SOCO")  contributed  all its  assets and  operations,  subject to
certain  limitations,  in the  Wattenberg  Field of Colorado  ("Wattenberg")  to
Patina (the "Contribution"). In connection with the Contribution, Patina assumed
$75 million of bank debt from SOCO.

         With the closing of the  transaction,  Patina  holds  interests in over
3,600 Wattenberg  wells. As of December 31, 1995, Patina has net proved reserves
of 82 million barrels of oil equivalent  ("BOE"),  over two-thirds of which were
natural gas. Patina's production currently exceeds 20,000 BOE per day.

         SOCO owns an aggregate of 14,000,000  shares of common stock of Patina,
of which  12,000,000 are common stock,  par value $.01 per share ("Patina Common
Stock"), and 2,000,000 are Series A Common Stock. The Series A Common Stock is a
special series of common stock of Patina having three votes per share,  and will
convert  automatically into ordinary Patina Common Stock (i.e.,  shares with one
vote per share) upon transfer of those shares by SOCO to a  non-affiliate  or if
Patina ceases to be included in the consolidated  financial  statements of SOCO.
Thus, SOCO owns 70% of the outstanding  shares of the common stock of Patina and
holds 75% of the voting power of Patina's common stock.

         Pursuant  to the terms of the  Merger,  the  shares of common  stock of
Gerrity issued and  outstanding  immediately  prior to the effective time of the
Merger were  converted  into an aggregate of 6,000,000  shares of Patina  Common
Stock and 3,000,000 five-year warrants initially to purchase one share of Patina
Common Stock at an exercise price of $12.50 per share (the "Patina Warrants").

         In addition,  pursuant to an exchange offer, approximately 75.3% of the
depositary shares  representing  Gerrity's $12 convertible  preferred stock were
accepted  by Patina  for  exchange  into  approximately  1.2  million  shares of
Patina's 7 1/8% convertible  preferred stock (the "Patina Preferred Stock"). The
Patina  Preferred Stock has a liquidation  preference of $25.00 per share,  pays
quarterly  dividends  at the rate of 7 1/8% per  year  and is  convertible  into
Patina Common Stock at a conversion  price of $12.30,  which conversion price is
subject to  downward  adjustment  after the Merger to equal 123% of the  average
closing  price of the Patina  Common stock for the ten trading days  immediately
following the 60th day after the Merger,  subject to a minimum  conversion price
of $8.61.

         Patina  also issued a  five-year  warrant for 500,000  shares of Patina
Common  Stock,  at a price equal to the average  closing price during the 10-day
period  following the Merger,  to Robert W. Gerrity,  who resigned as an officer
and director of Gerrity in connection with the transaction.

         Patina's  long-term debt,  after all transaction  costs, is expected to
approximate  $215  initially.  Patina has  entered  into a $240  million  credit
facility  with  Texas  Commerce  Bank  National  Association,  which  serves  as
Administrative Agent, NationsBank of Texas, N.A., Documentation






Agent,  and CIBC,  Inc.,  Credit  Lyonnais New York Branch and Wells Fargo Bank,
N.A., as co- agents.  The facility will be used to refinance  debt to be assumed
in the transaction,  including  approximately  $100 million of bank debt assumed
from SOCO and Gerrity and up to $100  million of Gerrity's  senior  subordinated
notes if the  holders  exercise  their  right to put the notes to  Gerrity.  $87
million  of the  facility  may be  used  only  to  repurchase  Gerrity's  senior
subordinated  notes.  The balance of the facility  will be available for working
capital.

         The  Amended  and  Restated  Agreement  and Plan of Merger  dated as of
January  16, 1996 as amended  and  restated  as of March 20,  1996 (the  "Merger
Agreement"),  which was negotiated between  representatives of SOCO and Gerrity,
provides  that  any   contracts  or   transactions   (other  than   transactions
contemplated  by  the  Merger   Agreement)   involving  Patina  or  any  of  its
subsidiaries  in which SOCO or any of its  subsidiaries  has any interest (other
than an interest  solely as a stockholder of Patina) shall be approved by either
(a) a majority of the disinterested directors of Patina or (b) a majority of any
committee  established by the Patina Board of Directors that consists  solely of
directors that are  disinterested.  In addition,  in accordance  with the Merger
Agreement,  SOCO and Patina have entered into  certain  agreements,  including a
Business     Opportunity     Agreement,     Corporate    Services     Agreement,
Cross-Indemnification  Agreement and Registration  Rights  Agreement,  that will
govern the relationship between SOCO and Patina following the Merger.

         The  descriptions  of  the  Merger  Agreement,   Business   Opportunity
Agreement,  Corporate Services  Agreement,  Cross-Indemnification  Agreement and
Registration  Rights  Agreement  included in this Report are  summaries  and are
qualified in their entirety by the respective  terms of such  agreements,  which
are filed as exhibits to this Report and are incorporated herein by reference.
