          defined in the Merger  Agreement),  in each case regardless of whether
          such  Liabilities  exist or arise  before,  at or after the  Effective
          Time; provided, however, that any Liabilities disclosed or required by
          GAAP to be disclosed on a balance sheet for Patina as of the Effective
          Time (or in the notes  thereto)  that are not  disclosed in the Patina

     (j) "Snyder  Indemnified  Parties"  shall mean  Snyder and its  Affiliates,
other than Patina and its  subsidiaries,  and any officer,  director,  employee,
agent or other  representative  thereof  (individually,  a  "Snyder  Indemnified

                                                      -2-


     2. Indemnification.

          (a)  Patina  shall  defend,  indemnify  and hold  harmless  the Snyder
     Indemnified Parties against any and all Patina Liabilities,  whether or not
     the result of the sole or partial  negligence or otherwise culpable conduct
     or fault of one or more of the Snyder Indemnified Parties.

          (b)  Snyder  shall  defend,  indemnify  and hold  harmless  the Patina
     Indemnified Parties against any and all Snyder Liabilities,  whether or not
     the result of the sole or partial  negligence or otherwise culpable conduct
     or fault of one or more of the Patina Indemnified Parties.

     3.  Indemnification  Procedure.  Each person to be indemnified  pursuant to
this  Agreement  (an  "Indemnified  Party")  agrees to give prompt notice to the
indemnifying  party of the assertion of any claim,  or the  commencement  of any
suit, action or proceeding,  brought against or sought to be collected from such
Indemnified  Party (each a "Third Party Claim"),  in respect of which  indemnity
may be sought by such Indemnified Party under this Agreement;  provided that the
omission so to promptly  notify the  indemnifying  party with respect to a Third
Party Claim  brought  against or sought to be  collected  from such  Indemnified
Party will not relieve the  indemnifying  party from any  Liability  that it may
have to such  Indemnified  Party under this Agreement  except to the extent that
such failure has materially  prejudiced such indemnifying  party with respect to
the  defense of such Third  Party  Claim.  If any  Indemnified  Party shall seek
indemnity  under this  Agreement  with  respect to a Third Party  Claim  brought
against or sought to be collected from such Indemnified  Party, the indemnifying
party  shall be  entitled  to  participate  therein  and,  to the extent that it
wishes,  to assume and direct the defense and  settlement  thereof  with counsel
satisfactory to such Indemnified Party. After notice from the indemnifying party
to an  Indemnified  Party of its  election  to assume and direct the defense and
settlement of a Third Party Claim brought against or sought to be collected from
such Indemnified  Party that such  indemnifying  party is entitled to assume and
direct under the terms  hereof,  the  indemnifying  party shall not be liable to
such  Indemnified  Party under this  Agreement  for any legal or other  expenses
subsequently  incurred by such Indemnified  Party in connection with the defense
thereof other than reasonable  costs of  investigation,  unless the Indemnifying
Party and the Indemnified Party are both named parties to any such action, claim
or demand  and  representation  of both  parties  by the same  counsel  would be
inappropriate  due to actual or potential  conflicts of interest  between  them.
Notwithstanding  the foregoing  provisions  of this Section 3, the  indemnifying
party shall not (A) without the prior written  consent of an Indemnified  Party,
effect any  settlement  of any pending or  threatened  proceeding  in respect of
which such Indemnified Party is, or with reasonable  foreseeability,  could have
been a party and indemnity could have been sought  hereunder by such Indemnified
Party for a Third Party Claim  brought  against or sought to be  collected  from
such  Indemnified  Party,  unless  such  settlement  includes  an  unconditional
release,  in form and substance  satisfactory to the Indemnified  Party, of such
Indemnified  Party from all Liability  arising out of such proceeding  (provided
that, whether or not such a release is required to be obtained, the indemnifying
party shall remain  liable to such  Indemnified  Party in  accordance  with this
Agreement in the event that a Third Party Claim is subsequently  brought against
or sought to be collected from such Indemnified  Party) or (B) be liable for any
settlement of any Third Party Claim brought against or sought to be


                                                      -3-


collected from an Indemnified Party effected without such  indemnifying  party's
written consent (which shall not be unreasonably withheld),  but if settled with
such indemnifying  party's written con sent, or if there is a final judgment for
the plaintiff in any such Third Party Claim, such indemnifying  party agrees (to
the extent stated above) to indemnify the Indemnified Party from and against any
loss,  liability,  claim,  damage or  expense  by reason or such  settlement  or
judgment.  The  indemnification  required  by this  Agreement  shall  be made by
periodic  payments of the amount thereof during the course of the  investigation
or defense, as and when bills are received or loss, liability,  claim, damage or
expense is incurred.

     4. Insurance.

     (a)  Notwithstanding  any provision to the contrary herein, an indemnifying
party  hereunder  shall have no  obligation  for a liability or any part thereof
sought to be indemnified  by an Indemnified  Party pursuant to this Agreement to
the extent that the  Indemnified  Party has received  payment from an insurer on
account of such liability,  which payment has not been offset through a matching
deductible or premium adjustments made on account of such payment.

     (b) To the  extent  that an  Indemnified  Party  may have  insurance  for a
liability or any part thereof  sought to be  indemnified  under this  Agreement,
until an insurer  makes  payment on account  thereof,  the parties shall proceed
with  indemnification  under this Agreement as if the  Indemnified  Party is not
covered by such insurance.  An indemnifying party which has paid all or any part
of an  indemnification  claim shall then be reimbursed by the Indemnified  Party
from insurance payment later received, if any, which payment has not been offset
through a matching  deductible  or premium  adjustments  made on account of such
payment.

     5. Assignment.

     Except  by  operation  of law or in  connection  with  the  sale  of all or
substantially  all the assets of a party  hereto,  this  Agreement  shall not be
assignable,  in whole or in part,  directly or  indirectly,  by any party hereto
without the written  consent of the other  party;  and any attempt to assign any
rights or obligations arising under this Agreement without such consent shall be
void; provided,  however, that the provisions of this Agreement shall be binding
upon, inure to the benefit of and be enforceable by the parties hereto and their
respective successors and permitted assigns.

     6. Further Assurances.

     Subject to the provisions hereof,  the parties hereto shall make,  execute,
acknowledge and deliver such other instruments and documents,  and take all such
other actions, as may be reasonably required in order to effectuate the purposes
of this  Agreement  and to  consummate  the  transactions  contemplated  hereby.
Subject to the provisions hereof,  each of the parties shall, in connection with
entering into this Agreement,  performing its  obligations  hereunder and taking
any  and  all  actions  relating  hereto,   comply  with  all  applicable  laws,
regulations, orders and decrees, obtain all required


                                                      -4-


consents  and  approvals  and make all required  filings  with any  governmental
agency,  other  regulatory  or  administrative  agency,  commission  or  similar
authority and promptly  provide the other parties with all such  information  as
they may reasonably request in order to be able to comply with the provisions of
this sentence.

     7. Parties in Interest.

     Except as herein otherwise specifically provided, nothing in this Agreement
expressed or implied is intended to confer any right or benefit upon any person,
firm or corporation other than the parties,  the Snyder Indemnified Parties, the
Patina  Indemnified  Parties  and  their  respective  successors  and  permitted
assigns.

     8. Waivers, Etc.

     No failure or delay on the part of the parties in  exercising  any power or
right  hereunder  shall  operate  as a waiver  thereof,  nor shall any single or
partial   exercise  of  any  such  right  or  power,   or  any   abandonment  or
discontinuance of steps to enforce such a right or power,  preclude any other or
further  exercise  thereof  or the  exercise  of any other  right or  power.  No
modification  or waiver of any  provision of this  Agreement  nor consent to any
departure by the parties  therefrom  shall in any event be effective  unless the
same shall be in  writing,  and then such waiver or consent  shall be  effective
only in the specific instance and for the purpose for which given.

     9. Severability.

     If any term,  provision,  covenant or restriction of this Agreement is held
by a court of competent  jurisdiction to be invalid, void or unenforceable,  the
remainder of the terms, provisions,  covenants and restrictions set forth herein
shall remain in full force and effect and shall in no way be affected,  impaired
or invalidated.  It is hereby stipulated and declared to be the intention of the
parties that they would have executed the remaining terms, provisions, covenants
and restrictions  without including any thereof which may be hereafter  declared
invalid,  void or  unenforceable.  In the event that any such  term,  provision,
covenant  or  restriction  is held to be  invalid,  void or  unenforceable,  the
parties  hereto  shall  use  their  reasonable  efforts  to find and  employ  an
alternate  means to achieve  the same or  substantially  the same result as that
contemplated by such term, provision, covenant or restriction.

     10. Change of Law.

     If,  due  to  any  change  in  applicable   law  or   regulations   or  the
interpretation  thereof  by a  court  of  law or  other  governing  body  having
jurisdiction  subsequent  to the  date of  this  Agreement,  performance  of any
provision of this Agreement or any transaction  contemplated hereby shall become
impracticable  or  impossible,  the parties  hereto  shall use their  reasonable
efforts to find and employ


                                                      -5-


an alternative means to achieve the same or substantially the same result as the
contemplated by such provision.
