                          REGISTRATION RIGHTS AGREEMENT


     THIS REGISTRATION  RIGHTS AGREEMENT (this  "Agreement")  dated as of May 2,
1996,  is between  PATINA OIL & GAS  CORPORATION,  a Delaware  corporation  (the
"Company"), and the undersigned stockholder (the "Holder").

                              W I T N E S S E T H:

     WHEREAS,  the Company,  the Holder,  Patina Merger Corporation,  a Delaware
corporation,  and Gerrity Oil & Gas Corporation,  a Delaware  corporation,  have
entered into that  certain  Amended and  Restated  Agreement  and Plan of Merger
dated as of January 16, 1996 and amended and  restated as of March 20, 1996 (the
"Merger Agreement").

     WHEREAS,  pursuant to the Merger  Agreement,  after the Effective  Time (as
that term is defined in the Merger  Agreement) the Holder will own a substantial
number of shares of common stock, par value $.01 per share (the "Common Stock"),
of the  Company,  as well as a  substantial  number of shares of Series A Common
Stock,  par  value  $.01 per  share  (the  "Series  A Common  Stock"),  which is
convertible under certain circumstances into Common Stock; and

     WHEREAS,  the  Common  Stock  will be  registered  under  Section 12 of the
Securities and Exchange Act of 1934 (the "Exchange Act"); and
 
     WHEREAS,   under  the  provisions  of  the  Securities  Act  of  1933  (the
"Securities  Act") and the  General  Rules and  Regulations  promulgated  by the
Securities and Exchange Commission (the "SEC") thereunder,  the Holder is or may
be  limited in the manner of  selling  the shares of Common  Stock  owned by the
Holder,  absent registration under the Securities Act of the sale of such shares
or the availability of another  exemption from the registration  requirements of
the Securities Act; and

     WHEREAS, the Company desires to establish certain other restrictions on the
sale of the shares of Common Stock owned by the Holder,  and the Company and the
Holder desire to set forth certain registration rights as to such shares;

     NOW,  THEREFORE,  in consideration of the premises and the mutual covenants
and agreements contained herein, the parties hereto hereby agree as follows:

     1. Agreement Not to Sell or Transfer Restricted Stock For A Period of Time.
The Holder  agrees that it will not offer,  sell,  contract to sell or otherwise
dispose  of any  shares  of Common  Stock or any  security  convertible  into or
exchangeable for Common Stock for a period of 180 days after the Effective Time;
provided,  however,  that the  foregoing  shall not restrict any offers,  sales,
contracts to sell or other dispositions to any affilate of the Holder.


                                                         1



     2. Demand Registration.

          (A) Request for Registration.  As used in this Agreement,  "Restricted
     Stock"  shall  mean all shares of Common  Stock  owned by the Holder at the
     Effective  Time,  together  with any  securities  issued or  issuable  with
     respect to any such Common Stock by way of stock dividend or stock split or
     in  connection  with a  combination  of shares,  recapitalization,  merger,
     consolidation  or other  reorganization,  or upon  conversion  of  Series A
     Common Stock owned by the Holder at the Effective Time, or otherwise. As to
     any particular  shares of Restricted  Stock, such securities shall cease to
     be Restricted  Stock when (a) a registration  statement with respect to the
     sale of such  securities  shall have become  effective under the Securities
     Act and such securities shall have been disposed of in accordance with such
     registration statement,  (b) such securities shall have been distributed to
     the public  pursuant  to Rule 144 (or any  successor  provision)  under the
     Securities Act (provided that if all Restricted  Stock is then eligible for
     sale pursuant to Rule 144, then all such Restricted Stock shall cease to be
     Restricted   Stock),   (c)  such  securities   shall  have  been  otherwise
     transferred,  new certificates  representing  such securities not bearing a
     legend  restricting  transfer  shall have been delivered by the Company and
     subsequent disposition of such securities shall not require registration or
     qualification  of such  securities  under the Securities Act or any similar
     state  law then in  force,  (d) such  securities  shall  have  ceased to be
     outstanding,  or (e) the Holder or Holders  thereof  shall agree in writing
     that such Restricted  Stock shall no longer be Restricted Stock (the Holder
     and any permitted  assignee of the Holder's rights and duties hereunder are
     referred to herein as the "Holders" or individually as a "Holder"). Subject
     to the conditions and limitations set forth in Section 5 of this Agreement,
     at any time  after the  limitation  period  referred  to in  Section 1, the
     Holder or Holders of Restricted Stock holding in the aggregate 5% in number
     of shares  of the  Restricted  Stock  then  outstanding  may make a written
     request for registration  under the Securities Act of all or part of its or
     their   Restricted   Stock   pursuant   to  this   Section  2  (a   "Demand
     Registration"),  provided  that the  number of shares of  Restricted  Stock
     proposed to be sold shall be at least 5% of the aggregate  number of shares
     of  Restricted  Stock then  outstanding,  but in no event less than 500,000
     shares of Restricted Stock (subject to appropriate adjustment for any stock
     dividend,    stock   split,    combination,    recapitalization,    merger,
     consolidation,  reorganization  or similar  occurrence).  Such request will
     specify the aggregate  number of shares of Restricted  Stock proposed to be
     sold and will also  specify the  intended  method of  disposition  thereof.
     Within  ten days after  receipt  of such  request,  the  Company  will give
     written  notice  of such  registration  request  to all  other  Holders  of
     Restricted Stock and include in such registration all Restricted Stock with
     regard to which the Company has received  written  requests  for  inclusion
     therein  within  fifteen  business days after the receipt by the applicable
     Holders of the  Company's  notice.  Each such request will also specify the
     aggregate  number of shares of Restricted  Stock to be  registered  and the
     intended  method of  disposition  thereof.  No other party,  including  the
     Company  (but  excluding  other  Holders  of  Restricted  Stock),  shall be
     permitted to offer securities under any such Demand Registration unless the
     Holder or Holders  requesting  the  Demand  Registration  shall  consent in
     writing.

          (B) Priority on Demand Registrations.  If the Holders of a majority in
     number of  shares  of the  Restricted  Stock to be  registered  in a Demand
     Registration so elect,  the offering of such  Restricted  Stock pursuant to
     such Demand Registration shall be in the form of an

                                                         2




     underwritten  offering.  In such  event,  if the  managing  underwriter  or
     underwriters of such offering advise the Company and the Holders in writing
     that in their opinion the aggregate amount of Restricted Stock requested to
     be  included  in such  offering  is so large  that it will  materially  and
     adversely affect the success of such offering,  the Company will include in
     such  registration  the aggregate number of shares of Restricted Stock that
     in the opinion of such managing  underwriter  or  underwriters  can be sold
     without any such material  adverse effect,  and such number of shares shall
     be allocated pro rata among the Holders of Restricted Stock on the basis of
     the number of shares of Restricted  Stock  requested to be included in such
     registration  by the Holders.  To the extent shares of Restricted  Stock so
     requested to be registered are excluded from such  offering,  then a Holder
     of such  Restricted  Stock  shall have the right to one  additional  Demand
     Registration  under this  Section with  respect to such  Restricted  Stock,
     provided  that the failure of such  Restricted  Stock to be  registered  is
     through no fault of such Holder.

          (c) Selection of Underwriters and Counsel.  If any Demand Registration
     is in the form of an  underwritten  offering,  the Holders of a majority in
     number of the shares of Restricted  Stock to be registered  will select and
     obtain the  services of the  investment  banker or  investment  bankers and
     manager or managers  that will  administer  the offering and the counsel to
     such  investment  bankers  and  managers;  provided  that  such  investment
     bankers,  managers  and  counsel  must be approved  by the  Company,  which
     approval shall not be unreasonably withheld.

     3. Piggyback  Registration.  If the Company proposes to file a registration
statement  under the  Securities  Act with  respect to an  offering  for its own
account  of any  class  of its  equity  securities  (other  than a  registration
statement  on  Form  S-8 (or  any  successor  form)  or any  other  registration
statement  relating solely to director and/or employee benefit plans or filed in
connection  with an  exchange  offer,  a  transaction  to which Rule 145 (or any
successor  rule) under the  Securities  Act applies or an offering of securities
solely to the Company's existing  stockholders) (each, an "Excluded Registration
Statement"),  then the Company  shall in each case give  written  notice of such
proposed filing to the Holders of Restricted  Stock as soon as practicable  (but
no later than five business days) before the  anticipated  filing date, and such
notice  shall offer such  Holders  the  opportunity  to register  such number of
shares of  Restricted  Stock as each such  Holder may  request.  Each  Holder of
Restricted  Stock  desiring to have such holder's  Restricted  Stock included in
such  registration  statement shall so advise the Company in writing within five
business days after the date of the Company's  notice,  setting forth the amount
of such Holder's  Restricted Stock for which  registration is requested.  If the
Company's offering is to be an underwritten offering, the Company shall, subject
to the further provisions of this Agreement, use its reasonable efforts to cause
the managing underwriter or underwriters of a proposed  underwritten offering to
permit the  Holders of the  Restricted  Stock  requested  to be  included in the
registration  for such  offering to include such  securities in such offering on
the same terms and conditions as any similar  securities of the Company included
therein.  Moreover,  if the  registration  of which  the  Company  gives  notice
involves an underwriting,  the right of each Holder to registration  pursuant to
this Section 3 shall,  unless the Company  otherwise agrees, be conditioned upon
such Holder's  participation as a seller in such  underwriting and its execution
of an  underwriting  agreement  with the managing  underwriter  or  underwriters
selected  by  the  Company.  Notwithstanding  the  foregoing,  if  the  managing
underwriter or  underwriters  of such offering  deliver a written opinion to the
Holders of Restricted Stock that

                                                         3



either because of (A) the kind of securities  that the Holders,  the Company and
any other person or entities  intend to include in such offering or (B) the size
of the offering that the Holders,  the Company and other persons intend to make,
the  success of the  offering  would be  materially  and  adversely  affected by
inclusion of the  Restricted  Stock  requested  to be included,  then (i) in the
event that the size of the offering is the basis of such managing  underwriter's
opinion,  the  number of shares to be  offered  for the  accounts  of Holders of
Restricted Stock shall be reduced pro rata to the extent necessary to reduce the
total  amount of  securities  to be  included  in such  offering  to the  amount
recommended  by such  managing  underwriter  or  underwriters;  provided that if
securities  are being  offered for the  account of other  persons or entities as
well as the Company,  such reduction  shall not represent a greater  fraction of
the number or kind of securities intended to be offered by Holders of Restricted
Stock than the fraction of similar  reductions  imposed on such other persons or
entities over the amount of securities of such kind they intended to offer;  and
(ii) in the event that the  combination of securities to be offered is the basis
of such managing  underwriter's opinion, (x) the Restricted Stock to be included
in such offering  shall be reduced as described in clause (i) above  (subject to
the  proviso  in clause  (i) ) or, (y) if the  actions  described  in clause (x)
would,  in  the  judgment  of  the  managing  underwriter,  be  insufficient  to
substantially  eliminate  the adverse  effect that  inclusion of the  Restricted
Stock  requested to be included  would have on such  offering,  such  Restricted
Stock will be excluded from such offering. Any Restricted Stock excluded from an
underwriting  shall be withdrawn from  registration  and shall not,  without the
consent of the Company and the manager of the underwriting,  be transferred in a
public  distribution  prior to the  earlier  of 90 days (or such  other  shorter
period  of time as the  manager  of the  underwriting  may  require)  after  the
effective  date of the  registration  statement  or 120 days  after the date the
Holders of such Restricted Stock are notified of such exclusion.

     4. Registration  Procedures.  Whenever,  pursuant to Section 2 or 3, any of
the Holders of  Restricted  Stock has  requested  that any  Restricted  Stock be
registered,  the  Company  will,  subject  to the  provisions  of Section 5, use
reasonable  best  efforts  to  effect  the  registration  and  the  sale of such
Restricted  Stock in accordance with the intended method of disposition  thereof
as promptly as practicable, and in connection with any such request, the Company
will:

          (A) in  connection  with a request  pursuant to Section 2, prepare and
     file with the SEC,  not later  than 60 days  after  receipt of a request to
     file  a  registration   statement  with  respect  to  Restricted  Stock,  a
     registration statement on any form for which the Company then qualifies and
     which counsel for the Company shall deem  appropriate  and which form shall
     be available for the sale of such  Restricted  Stock in accordance with the
     intended  method  of  distribution  thereof,  and use its  reasonable  best
     efforts to cause such registration statement to become effective;  provided
     that if the Company  shall  furnish to the Holders  making such a request a
     certificate  signed by  either  the chief  financial  officer  or the chief
     accounting officer of the Company stating that in such officer's good faith
     judgment it would be significantly  disadvantageous to the Company for such
     a registration  statement to be filed on or before the date filing would be
     required  (including without limitation the required disclosure of material
     non-public  information  prior  to the  time  that it  would  otherwise  be
     required  by  applicable  law  or  securities  exchange  regulation  to  be
     disclosed), the Company shall have an additional period of not more than 90
     days within which to file such registration  statement and provided further
     (i) that,  before  filing a  registration  statement or  prospectus  or any
     amendments or supplements  thereto, the Company will furnish to one counsel
     selected by the Holders of a

                                                         4



     majority  in  number  of shares of the  Restricted  Stock  covered  by such
     registration  statement copies of all such documents  proposed to be filed,
     which  documents  will be subject to the review of such  counsel,  and (ii)
     that after the  filing of the  registration  statement,  the  Company  will
     promptly notify each of the selling Holders of Restricted Stock of any stop
     order issued or, to the knowledge of the Company, threatened by the SEC and
     take all  reasonable  actions to prevent the entry of such stop order or to
     remove it if entered;

          (B) in connection  with a registration  pursuant to Section 2, prepare
     and file with the SEC such amendments and supplements to such  registration
     statement  and  the  prospectus  used  in  connection  therewith  as may be
     necessary to keep such registration statement effective for a period of not
     less  than 180 days or such  shorter  period  as shall  terminate  when all
     shares of Restricted Stock covered by such registration statement have been
     sold (but not before the  expiration  of the 90-day  period  referred to in
     Section 4(3) of the Securities Act and Rule 174 thereunder, if applicable),
     and comply with the  provisions of the  Securities  Act with respect to the
     disposition of all securities covered by such registration statement during
     such period in accordance  with the intended  methods of disposition by the
     selling Holders thereof set forth in such registration statement;

          (C) as soon as reasonably practicable,  furnish to each of the selling
     Holders,  prior  to  filing  a  registration  statement,   copies  of  such
     registration  statement as proposed to be filed, and thereafter  furnish to
     such selling Holders such number of copies of such registration  statement,
     each amendment and  supplement  thereto (in each case, if specified by such
     Holder,  including all exhibits thereto),  the prospectus  included in such
     registration  statement  (including each  preliminary  prospectus) and such
     other  documents  as a selling  Holder may  reasonably  request in order to
     facilitate the  disposition  of the Restricted  Stock owned by such selling
     Holder;

          (D) with  reasonable  promptness,  use its reasonable  best efforts to
     register  or  qualify  (or  cause  to  be  registered  or  qualified)  such
     Restricted  Stock  under  such  other  securities  or blue sky laws of such
     jurisdictions  within the United States as any selling  Holder (or managing
     underwriter in the case of an underwritten  offering)  reasonably (in light
     of  such  selling  Holder's  or  managing  underwriter's  intended  plan of
     distribution) requests and do any and all other acts and things that may be
     reasonably  necessary  or  advisable  to  enable  such  selling  Holder  to
     consummate the disposition in such  jurisdictions  of the Restricted  Stock
     owned  by such  selling  Holder;  provided  that  the  Company  will not be
     required to (i) qualify generally to do business in any jurisdiction  where
     it would not otherwise be required to qualify but for this  subsection (D),
     (ii) subject itself to taxation in any such  jurisdiction  or (iii) consent
     to general service of process in any such jurisdiction;

          (E) with  reasonable  promptness,  use its reasonable  best efforts to
     cause the  Restricted  Stock covered by such  registration  statement to be
     registered  with  or  approved  by  such  other  governmental  agencies  or
     authorities as may be necessary by virtue of the business and operations of
     the Company to enable the selling  Holder or Holders  thereof to consummate
     the disposition of such Restricted Stock;


                                                         5



          (F) promptly notify each selling Holder of such  Restricted  Stock, at
     any time when a  prospectus  relating  thereto is required to be  delivered
     under the  Securities  Act,  of the  occurrence  of any event  known to the
     Company  requiring  the  preparation  of a supplement  or amendment to such
     prospectus  so that,  as  thereafter  delivered to the  purchasers  of such
     Restricted Stock, such prospectus will not contain an untrue statement of a
     material  fact or omit to state any  material  fact  required  to be stated
     therein or  necessary to make the  statements  therein not  misleading  and
     promptly  make  available to each  selling  Holder any such  supplement  or
     amendment;

          (G) in connection with a request  pursuant to Section 2, enter into an
     underwriting  agreement in customary  form,  the form and substance of such
     underwriting agreement being subject to the reasonable  satisfaction of the
     Company;

          (H) with  reasonable  promptness  make available for inspection by any
     selling Holder, any underwriter  participating in any disposition  pursuant
     to such registration statement, and any attorney, accountant or other agent
     retained  by any such  selling  Holder or  underwriter  (collectively,  the
     "Inspectors"),   all  financial  and  other  records,  pertinent  corporate
     documents and properties of the Company (collectively,  the "Records"),  as
     well as access at reasonable times to the Company's executive officers, key
     employees,  independent  accountants and independent  reserve  engineers as
     shall  be  reasonably  necessary  to  enable  them to  exercise  their  due
     diligence responsibility, and cause the Company's officers and employees to
     supply all  information  reasonably  requested for such purpose by any such
     Inspector  in  connection  with  such  registration  statement;   provided,
     however,  that the selection of any Inspector  other than a selling  Holder
     shall  be  subject  to the  consent  of the  Company,  which  shall  not be
     unreasonably  withheld.   Each  Inspector  that  actually  reviews  Records
     supplied  by  the  Company  that  include   information  that  the  Company
     determines, in good faith, to be confidential ("Confidential  Information")
     shall be required,  prior to any such review,  to execute an agreement with
     the  Company   providing  that  such  Inspector   shall  not  disclose  any
     Confidential  Information  unless such disclosure is required by applicable
     law or legal process.  Each selling Holder of Restricted  Stock agrees that
     Confidential  Information  obtained  by it as a result of such  inspections
     shall not be used by it as the basis for any  transactions in securities of
     the Company unless and until such  information is made generally  available
     to the public.  Each selling Holder of Restricted Stock further agrees that
     it will,  upon learning  that  disclosure of  Confidential  Information  is
     sought in a court of competent jurisdiction, give notice to the Company and
     allow the Company,  at its  expense,  to  undertake  appropriate  action to
     prevent  disclosure of the  Confidential  Information.  Each selling Holder
     also agrees that the due  diligence  investigation  made by the  Inspectors
     shall be  conducted  in a manner  that will not  unreasonably  disrupt  the
     operations of the Company or the work  performed by the Company's  officers
     and employees;

          (I) in the event such sale is  pursuant to an  underwritten  offering,
     use its reasonable  best efforts to obtain a comfort letter or letters from
     the Company's independent public accountants in customary form and covering
     such  matters of the type  customarily  covered  by comfort  letters as the
     managing underwriter reasonably requests;


                                                         6



          (J)  otherwise  use its  reasonable  best  efforts to comply  with all
     applicable  rules and  regulations  of the SEC,  and make  available to its
     security holders, as soon as reasonably practicable,  an earnings statement
     covering a period of twelve months,  beginning  within two months after the
     effective date of the  registration  statement,  which  earnings  statement
     shall satisfy the provisions of Section 11(a) of the Securities Act; and

          (K) with  reasonable  promptness,  use its reasonable  best efforts to
     cause all such Restricted Stock to be listed on each securities exchange on
     which the Common  Stock of the Company is then  listed,  provided  that the
     applicable listing requirements are satisfied.

     Each selling  Holder of Restricted  Stock agrees that,  upon receipt of any
notice from the Company of the  happening of any event of the kind  described in
subsection  (F)  hereof,   such  selling   Holder  will  forthwith   discontinue
disposition of Restricted Stock pursuant to the registration  statement covering
such Restricted  Stock until such selling  Holder's receipt of the copies of the
supplemented or amended prospectus  contemplated by subsection (F) hereof,  and,
if so directed by the Company,  such selling  Holder will deliver to the Company
(at the Company's expense) all copies,  other than permanent file copies then in
such selling  Holder's  possession,  of the prospectus  covering such Restricted
Stock  current at the time of receipt of such  notice.  In the event the Company
shall give any such notice,  the Company  shall  extend the period  during which
such  registration  statement  shall be  maintained  effective  pursuant to this
Agreement  (including the period referred to in subsection (B)) by the number of
days during the period from and  including the date of the giving of such notice
pursuant to  subsection  (F) hereof to and  including the date when each selling
Holder of Restricted  Stock covered by such  registration  statement  shall have
received the copies of the  supplemented or amended  prospectus  contemplated by
subsection (F) hereof.  Each selling Holder also agrees to notify the Company if
any event  relating  to such  selling  Holder  occurs  that  would  require  the
preparation  of a  supplement  or  amendment  to the  prospectus  so  that  such
prospectus  will not contain an untrue  statement of a material  fact or omit to
state a material  fact  required to be stated  therein or  necessary to make the
statements therein not misleading.

     5. Conditions and Limitations.

          (A) The Company's  obligations under Section 2 shall be subject to the
     following limitations:

               (i) the Company need not file a registration statement either (x)
          during  the  period  starting  with  the  date  60 days  prior  to the
          Company's  estimated  date of filing  of, and ending 90 days after the
          effective date of, any registration statement pertaining to securities
          of the  Company  (other  than  an  Excluded  Registration  Statement),
          provided  that if such  Company  registration  statement  is not filed
          within 90 days  after the first date on which the  Company  notifies a
          Holder of  Restricted  Stock that it will delay a Demand  Registration
          pursuant to this clause (x), the Company may not further postpone such
          Demand Registration  pursuant to this clause; or (y) during the period
          specified in the first proviso of subsection (A) of Section 4;

               (ii) the  Company  shall not be  required  to furnish any audited
          financial  statements other than those audited statements  customarily
          prepared at the end of its

                                                         7



          fiscal year, or to furnish any unaudited  financial  information  with
          respect  to any  period  other  than its  regularly  reported  interim
          quarterly  periods  unless  in the  absence  of such  other  unaudited
          financial  information  the  registration  statement  would contain an
          untrue  statement  of material  fact or omit to state a material  fact
          required  to be stated  therein or  necessary  to make the  statements
          therein not misleading;

               (iii) except as provided in Section  2(B),  the Company shall not
          be required to file more than two Demand Registrations. A registration
          statement will not count as a Demand  Registration until it has become
          effective; and

               (iv)  the  Company  shall  have  received  the   information  and
          documents  specified in Section 6 and each  selling  Holder shall have
          observed or performed its other covenants and conditions  contained in
          such section.

          (B) The Company's  obligation  under Section 3 shall be subject to the
     limitations  and  conditions  specified in such section and in clauses (i),
     (ii) and (iv) of  subsection  (A) of this  Section 5, and to the  condition
     that the Company may at any time  terminate  its  proposal to register  its
     shares and  discontinue  its efforts to cause a  registration  statement to
     become or remain effective.

     6. Information from and Certain  Covenants of Holders of Restricted  Stock.
The  Holders for whom  Restricted  Stock are to be  registered  pursuant to this
Agreement shall provide to the Company such information regarding the Restricted
Stock to be so registered,  the Holder and the intended method of disposition of
such  Restricted  Stock as shall  reasonably be required in connection  with the
action  to be  taken.  Any  Holder  whose  Restricted  Stock  is  included  in a
registration  statement  pursuant to this Agreement  shall execute all consents,
powers of  attorney,  registration  statements  and other  documents  reasonably
required  to be signed by it in order to cause such  registration  statement  to
become  effective.  Each selling  Holder  covenants  that,  in disposing of such
Holder's  shares,  such Holder will comply with Rules l0b-2,  l0b-6 and l0b-7 of
the SEC adopted pursuant to the Exchange Act.

     7.  Registration  Expenses.  All Registration  Expenses (as defined herein)
will be borne by the Company.  Underwriting discounts and commissions applicable
to the sale of  Restricted  Stock shall be borne by each  selling  Holder of the
Restricted Stock to which such discount or commission relates,  and each selling
Holder  shall be  responsible  for the fees and  expenses of any legal  counsel,
accountants  or other  agents  retained  by such  selling  Holder  and all other
out-of-pocket  expenses  incurred by such selling Holder in connection  with any
registration under this Agreement.

     As used herein, the term Registration  Expenses means all expenses incident
to the Company's  performance of or compliance  with this Agreement  (whether or
not the  registration  in  connection  with which  such  expenses  are  incurred
ultimately becomes effective), including without limitation all registration and
filing fees,  fees and expenses of compliance  with  securities or blue sky laws
(including  reasonable fees and disbursements of counsel in connection with blue
sky  qualifications  of the  Restricted  Stock),  rating  agency fees,  printing
expenses,  messenger  and delivery  expenses  incurred by the Company,  internal
expenses incurred by the Company (including,  without  limitation,  all salaries
and  expenses of its  officers  and  employees  performing  legal or  accounting
duties), the fees and

                                                         8



expenses  incurred  in  connection  with the  listing  of the  securities  to be
registered on each securities exchange on which similar securities issued by the
Company are then listed,  and fees and  disbursements of counsel for the Company
and its independent certified public accountants  (including the expenses of any
comfort letters  required by or incident to such  performance),  securities acts
liability  insurance  (if the  Company  elects to obtain  such  insurance),  the
reasonable fees and expenses of any special experts  retained by the Company and
the fees and  expenses of other  persons  retained by the Company in  connection
with such registration.

     8. Indemnification; Contribution.

          (A)  Indemnification  by the Company.  The Company agrees to indemnify
     and hold harmless each selling  Holder of Restricted  Stock,  its officers,
     directors  and agents and each person,  if any,  who controls  such selling
     Holder  within the meaning of either  Section 15 of the  Securities  Act or
     Section  20 of the  Exchange  Act,  from and  against  any and all  losses,
     claims,  damages,  liabilities and expenses (including  reasonable costs of
     investigation) arising out of or based upon any untrue statement or alleged
     untrue statement of a material fact contained in any registration statement
     or  prospectus  relating to the  Restricted  Stock or in any  amendment  or
     supplement  thereto  or in  any  preliminary  prospectus  relating  to  the
     Restricted  Stock,  or arising out of or based upon any omission or alleged
     omission to state therein a material fact required to be stated  therein or
     necessary to make the statements therein not misleading,  except insofar as
     such losses, claims, damages,  liabilities or expenses arise out of, or are
     based upon,  any such untrue  statement or omission or  allegation  thereof
     based upon information  furnished in writing to the Company by such selling
     Holder or on such selling  Holder's  behalf  expressly  for use therein and
     provided further,  that with respect to any untrue statement or omission or
     alleged untrue  statement or omission made in any  preliminary  prospectus,
     the indemnity agreement contained in this subsection shall not apply to the
     extent that any such loss, claim, damage, liability or expense results from
     the fact that a copy of the final  prospectus  was not sent or given to the
     person asserting any such losses, claims, damages,  liabilities or expenses
     at or prior to the written confirmation of the sale of the Restricted Stock
     concerned  to such person if a final  prospectus  is made  available by the
     Company  on a timely  basis.  The  Company  also  agrees to  include in any
     underwriting  agreement  with  any  underwriters  of the  Restricted  Stock
     provisions   indemnifying   and   providing   for   contribution   to  such
     underwriters,  their  officers and  directors  and each person who controls
     such underwriters on substantially the same basis as the provisions of this
     Section 8  indemnifying  and  providing  for  contribution  to the  selling
     Holders.

          (B)  Indemnification  by Holders of  Restricted  Stock.  Each  selling
     Holder  agrees to indemnify  and hold  harmless the Company,  its officers,
     directors  and agents and each  person,  if any,  who  controls the Company
     within the meaning of either Section 15 of the Securities Act or Section 20
     of the Exchange Act, from and against any and all losses, claims,  damages,
     liabilities  and expenses  (including  reasonable  costs of  investigation)
     arising  out of or based  upon  any  untrue  statement  or  alleged  untrue
     statement of a material  fact  contained in any  registration  statement or
     prospectus  relating  to  the  Restricted  Stock  or in  any  amendment  or
     supplement  thereto  or in  any  preliminary  prospectus  relating  to  the
     Restricted  Stock,  or arising out of or based upon any omission or alleged
     omission to state therein a material fact required to be stated  therein or
     necessary to make the statements therein not

                                                         9



     misleading,  provided (i) that such losses, claims, damages, liabilities or
     expenses  arise out of, or are based  upon,  any such untrue  statement  or
     omission or allegation thereof based upon information  furnished in writing
     to the Company by such selling  Holder or on such selling  Holder's  behalf
     expressly for use therein,  (ii) that with respect to any untrue  statement
     or omission or alleged untrue statement or omission made in any preliminary
     prospectus,  the indemnity agreement contained in this subsection shall not
     apply to the extent that any such loss, claim, damage, liability or expense
     results from the fact that a copy of the final  prospectus  was not sent or
     given to the person asserting any such losses, claims, damages, liabilities
     or  expenses  at or prior to the  written  confirmation  of the sale of the
     Restricted Stock concerned to such person, and (iii) that no selling Holder
     shall  be  liable  for  any  indemnification  under  this  Section  8 in an
     aggregate  amount that  exceeds the total net  proceeds  (before  deducting
     expenses other than underwriting discounts or commissions) received by such
     selling  Holder  from the  offering.  Each  selling  Holder  also agrees to
     include in any underwriting  agreement with  underwriters of the Restricted
     Stock  provisions  indemnifying  and  providing  for  contribution  to such
     underwriters,  their officers and  directors,  and each person who controls
     such  underwriters,  on  substantially  the same basis as the provisions of
     this Section 8 indemnifying and providing for contribution to the Company.

          (C)  Conduct  of  Indemnification   Proceedings.   If  any  action  or
     proceeding  (including any governmental  investigation) shall be brought or
     asserted  against  any  indemnified  party  hereunder  in  respect of which
     indemnity may be sought from an indemnifying  party, the indemnifying party
     shall  assume the defense  thereof,  including  the  employment  of counsel
     reasonably  satisfactory to such  indemnified  party,  and shall assume the
     payment of all  expenses.  Such  indemnified  party shall have the right to
     employ  separate  counsel  in any such  action  and to  participate  in the
     defense thereof,  but the fees and expenses of such counsel shall be at the
     expense of such  indemnified  party unless (i) the  indemnifying  party has
     agreed to pay such fees and expenses or (ii) the  indemnifying  party shall
     have failed to assume the defense of such action or  proceeding  and employ
     counsel  reasonably  satisfactory to such  indemnified  party, or (iii) the
     named  parties to any such action or  proceeding  (including  any impleaded
     parties) include both such indemnified party and such  indemnifying  party,
     and such  indemnified  party shall have been  advised by counsel in writing
     that there may be one or more legal defenses  available to such indemnified
     party that are  different  from or  additional  to those  available  to the
     indemnifying  party (in which case, if such indemnified  party notifies the
     indemnifying  party in writing  that it elects to employ  separate  counsel
     reasonably  acceptable  to the  indemnifying  party at the  expense  of the
     indemnifying  party,  the  indemnifying  party  shall not have the right to
     assume  the  defense  of  such  action  or  proceeding  on  behalf  of such
     indemnified  party, it being  understood,  however,  that the  indemnifying
     party shall not, in  connection  with any one such action or  proceeding or
     separate but substantially similar or related actions or proceedings in the
     same  jurisdiction   arising  out  of  the  same  general   allegations  or
     circumstances,  be  liable  for the  fees  and  expenses  of more  than one
     separate firm of attorneys (together with appropriate local counsel) at any
     time for such indemnified  party, which firm shall be designated in writing
     by such indemnified  party). The indemnifying party shall not be liable for
     any  settlement  of any such  action or  proceeding  effected  without  its
     written consent,  but if settled with its written consent, or if there is a
     final  judgment  for the  plaintiff in any such action or  proceeding,  the
     indemnifying party agrees to

                                                        10



     indemnify  and hold harmless  such  indemnified  party from and against any
     loss or liability (to the extent stated above) by reason of such settlement
     or judgment.

          (D) Contribution.  If the indemnification provided for in this Section
     8 is  unavailable  to the Company or the selling  Holders in respect of any
     losses, claims, damages, liabilities or judgments referred to therein, then
     each such  indemnifying  party,  in lieu of indemnifying  such  indemnified
     party,  shall  contribute to the amount paid or payable by such indemnified
     party  as a  result  of  such  losses,  claims,  damages,  liabilities  and
     judgments,  in such  proportion as is  appropriate  to reflect the relative
     fault of each such party in connection  with such  statements or omissions,
     as well as any other relevant equitable considerations.  The relative fault
     of each such party shall be determined by reference to, among other things,
     whether the untrue or alleged  untrue  statement of a material  fact or the
     omission  or  alleged   omission  to  state  a  material  fact  relates  to
     information  supplied  by such party,  and the  parties'  relative  intent,
     knowledge, access to information and opportunity to correct or prevent such
     statement or omission.

          The  Company  and the  Holders  agree  that it  would  not be just and
     equitable if contribution  pursuant to this Section 8(D) were determined by
     pro rata  allocation  or by any other method of  allocation  which does not
     take account of the equitable considerations referred to in the immediately
     preceding paragraph.  The amount paid or payable by an indemnified party as
     a result of the losses, claims, damages,  liabilities or judgments referred
     to in the  immediately  preceding  paragraph  shall be deemed  to  include,
     subject to the  limitations  set forth above,  any legal or other  expenses
     reasonably   incurred  by  such   indemnified   party  in  connection  with
     investigation  or defending any such action or claim.  Notwithstanding  the
     provisions  of this Section  8(D),  no selling  Holder shall be required to
     contribute  any amount in excess of the amount by which the total  price at
     which the  Restricted  Stock of such  selling  Holder  were  offered to the
     public  exceeds the amount of any  damages  which such  selling  Holder has
     otherwise  been required to pay by reason of such untrue or alleged  untrue
     statement or omission or alleged  omission.  No person guilty of fraudulent
     misrepresentation  (within the meaning of Section  11(f) of the  Securities
     Act) shall be entitled to  contribution  from any person who was not guilty
     of such fraudulent misrepresentation.

     9.  Amendments.  This Agreement may be amended or modified upon the written
consent  thereto of the Company and the Holders of a majority of the  Restricted
Stock.

     10.  Assignments.  This  Agreement  shall be  binding  on and  inure to the
benefit of the respective successors and assigns of the parties hereto.

     11. Entire Agreement;  Governing Law. This Agreement constitutes the entire
agreement of the parties  relating to the subject matter hereof and all prior or
contemporaneous  written or oral  agreements are merged  herein.  This Agreement
shall be governed by the laws of the State of Delaware.
