     hereunder), if the other party shall (i) materially fail to perform its
     covenants or agreements contained herein required to be performed prior to
     the Closing Date, or (ii) materially breach or have breached any of its
     representations or warranties contained herein.

     XI.2    Remedies Upon Default or Failure to Close.
             ----------------------------------------- 

             (a)    If Buyer shall default in the performance of its obligations
     under this Agreement, and shall for this reason be unable to consummate
     this Agreement on the Closing Date in accordance with the terms hereof, and
     provided that Sellers are not then in material default of any of their
     obligations hereunder, Sellers shall be entitled to terminate this
     Agreement; provided, however, that Buyer shall have a period of ten (10)
     days following written notice from Sellers to cure any breach of this
     Agreement, if such breach is curable.

             (b)    If any Seller shall default in the performance of its
     obligations under this Agreement, including, but not limited to, the
     failure of any condition to Closing in Article VII or the failure to make
     any required delivery under Section 10.2, and shall for that reason be
     unable to consummate this Agreement on the Closing Date in accordance with
     the terms hereof, and if Buyer is not then in material default of any of
     its obligations hereunder, Buyer shall be entitled either (i) to waive any
     such defaults by such Seller and to require such Seller through specific
     performance (which such Seller acknowledges to be an appropriate remedy) to
     consummate the sale in accordance with the terms of this 

                                      -28-
<PAGE>
 
     Agreement or (ii) to terminate this Agreement; provided, however that
     Sellers shall have a period of ten (10) days following written notice from
     Buyer to cure any breach of this Agreement if such breach is curable. The
     availability of specific performance shall be in addition to any other
     remedies or claims for damages Buyer may have at law or in equity for
     breaches or defaults by Sellers of Sellers' obligations hereunder or for
     Buyer's remedies pursuant to Article XII hereof.

and all copies of such materials, whether so obtained before or after the
execution hereof, to the party furnishing the same.

                          SURVIVAL AND INDEMNIFICATION
                          ----------------------------

     XII.1   Indemnification of Seller.  Buyer shall indemnify and hold Sellers
             -------------------------                                         
and its Affiliates (the "Sellers Indemnitees") harmless from and against any and
all damages, including exemplary damages and penalties, losses, deficiencies,
costs, expenses, obligations, fines, expenditures, claims and liabilities,
including reasonable counsel fees and reasonable expenses of investigation,
defending and prosecuting litigation (collectively, the "Damages"), suffered by
the Sellers Indemnitees as a result of, caused by, arising out of, or in any way
relating to (a) any misrepresentation, breach of warranty, or nonfulfillment of
any agreement or covenant on the part of Buyer under this Agreement or any
misrepresentation in or omission from any list, schedule, certificate, or other
instrument furnished or to be furnished to Sellers by Buyer pursuant to the
terms of this Agreement, or (b) any liability or obligation (other than those
for which Buyer is being indemnified by Sellers hereunder) which pertains to the
ownership, operation or conduct of the Business or assets arising from any acts,
omissions, events, conditions or circumstances occurring on or after the Closing
Date.

     XII.2   Indemnification of Buyer.  Sellers shall, jointly and severally,
             ------------------------                                        
indemnify and hold Buyer and its Affiliates (the "Buyer Indemnitees") harmless
from and against any and all Damages suffered by Buyer Indemnitees as a result
of, caused by, arising out of, or in any way relating to (a) any
misrepresentation, breach of warranty, nonfulfillment of any agreement or
covenant on the part of Sellers under this Agreement, or any misrepresentation
in or omission from any list, schedule, certificate or other instrument
furnished or to be furnished to Buyer by 

                                      -29-
<PAGE>
 
Sellers pursuant to the terms of this Agreement, or (b) any liability or
obligation (other than those for which Seller is being indemnified by Buyer
hereunder) which pertains to the ownership, operation or conduct of the Business
or assets arising from any acts, omissions, events, conditions or circumstances
occurring prior to the Closing Date.

     XII.3   Demands.  Each indemnified party hereunder agrees that promptly 
             ------- 
upon its discovery of facts giving rise to a claim for indemnity under the
provisions of this Agreement, including receipt by it of notice of any demand,
assertion, claim, action or proceeding, judicial or otherwise, by any third
party (such third party actions being collectively referred to herein as the
"Claim"), with respect to any matter as to which it claims to be entitled to
indemnity under the provisions of this Agreement, it will give prompt notice
thereof in writing to the indemnifying party, together with a statement of such
information respecting any of the foregoing as it shall have. Such notice shall
include a formal demand for indemnification under this Agreement. The
indemnifying party shall not be obligated to indemnify the indemnified party
with respect to any Claim if the indemnified party knowingly failed to notify
the indemnifying party thereof in accordance with the provisions of this
Agreement in sufficient time to permit the indemnifying party or its counsel to
defend against such matter and to make a timely response thereto including,
without limitation, any responsive motion or answer to a complaint, petition,
notice or other legal, equitable or administrative process relating to the
Claim, only insofar as such knowing failure to notify the indemnifying party has
actually resulted in prejudice or damage to the indemnifying party.

     XII.4   Right to Contest and Defend.  The indemnifying party shall be
             ---------------------------                                  
entitled at its cost and expense to contest and defend by all appropriate legal
proceedings any Claim with respect to which it is called upon to indemnify the
indemnified party under the provisions of this Agreement; provided, that notice
of the intention to contest shall be delivered by the indemnifying party to the
indemnified party within twenty (20) days from the date of receipt by the
indemnifying party of notice by the indemnified party of the assertion of the
Claim.  Any such contest may be conducted in the name and on behalf of the
indemnifying party or the indemnified party as may be appropriate.  Such contest
shall be conducted by reputable counsel employed by the indemnifying party, but
the indemnified party shall have the right but not the obligation to participate
in such proceedings and to be represented by counsel of its own choosing at its
sole cost and expense.  The indemnifying party shall have full authority to
determine all action to be taken with respect thereto; provided, however, that
the indemnifying party will not have the authority to subject the indemnified
party to any obligation whatsoever, other than the performance of purely
ministerial tasks or obligations not involving material expense.  If the
indemnifying party does not elect to contest any such Claim, the indemnifying
party shall be bound by the result obtained with respect thereto by the
indemnified party, having used its reasonable best efforts in resolution.  At
any time after the commencement of the defense of any Claim, the indemnifying
party may request the indemnified party to agree in writing to the abandonment
of such contest or to the payment or compromise by the indemnified party of the

                                      -30-
<PAGE>
 
asserted Claim, whereupon such action shall be taken unless the indemnified
party determines that the contest should be continued, and so notifies the
indemnifying party in writing within fifteen (15) days of such request from the
indemnifying party.  If the indemnified party determines that the contest should
be continued, the indemnifying party shall be liable hereunder only to the
extent of the amount that the other party to the contested Claim had agreed
unconditionally to accept in payment or compromise as of the time the
indemnifying party made its request therefor to the indemnified party.

     XII.5   Cooperation.  If requested by the indemnifying party, the
             -----------                                              
indemnified party agrees to cooperate with the indemnifying party and its
counsel in contesting any Claim that the indemnifying party elects to contest
or, if appropriate, in making any counterclaim against the person asserting the
Claim, or any cross-complaint against any person, and the indemnifying party
will reimburse the indemnified party for any expenses incurred by it in so
cooperating.  If the indemnifying party has not chosen to contest a Claim, the
indemnifying party shall cooperate with the indemnified party and its counsel in
contesting any Claim at no cost or expense to the indemnified party.

     XII.6   Right to Participate.  The indemnified party agrees to afford the
             --------------------                                             
indemnifying party and its counsel the opportunity to be present at, and to
participate in, conferences with all persons, including governmental
authorities, asserting any Claim against the indemnified party or conferences
with representatives of or counsel for such persons at the indemnifying party's
sole cost and expense.

     XII.7   Payment of Damages.  The indemnifying party shall pay to the
             ------------------                                          
indemnified party in immediately available funds any amounts to which the
indemnified party may become entitled by reason of the provisions of this
Agreement subject to offset for any insurance proceeds actually received by the
indemnified party, such payment to be made within five days after any such
amounts are finally determined either by mutual agreement of the parties hereto
or pursuant to the final unappealable judgment of a court of competent
jurisdiction.  The availability of insurance proceeds shall not delay or
postpone any indemnification payment required hereunder.  If the indemnified
party both collects any such insurance proceeds and receives a payment from the
indemnifying party hereunder, and the sum of such proceeds and payment is in
excess of the amount payable with respect to the matter that is the subject of
the indemnity, then the indemnified party shall promptly refund to the
indemnifying party the amount of such excess, if permitted by the applicable
insurance policy(ies).  Except as otherwise provided in the preceding sentence,
the indemnified party's receipt of any such insurance proceeds shall not
eliminate or reduce the obligations of the indemnifying party or the rights of
the indemnified party hereunder, but shall reduce the amount of the obligation
in the amount of such insurance proceeds paid.

     XII.8   Survival of Representations and Warranties.  The representations 
             ------------------------------------------ 
and warranties contained in Articles IV and V of this Agreement shall survive
until the fifth anniversary date of

                                      -31-
<PAGE>
 
the Closing Date except for the representations and warranties in Sections 4.2,
4.3, 4.8, 4.12 and 5.1 which shall survive forever.
