      (b) Indemnification.

                (i) Indemnification of Buyer. From and after the date hereof,

      are not Assumed Liabilities.

               (ii) Indemnification of Seller. From and after the date hereof,
      Buyer shall indemnify and hold harmless Seller from and against any loss,

              (iii) Third Party Claims. If any third party shall notify any
      party to this Agreement (the "Indemnified Party") with respect to any
      matter which may give rise to a claim for indemnification against any
      other party to this Agreement (the "Indemnifying Party") under this
      Section 6(b), then the Indemnified Party shall notify each Indemnifying
      Party thereof. Within 30 days after receipt of notice of a particular
      matter, the Indemnifying Party may assume the defense of such matter if
      the Indemnifying Party admits responsibility and reaffirms its obligation
      for indemnification with respect to such matter; provided, however, that
      (A) the Indemnifying Party shall retain counsel reasonably acceptable to
      the Indemnified Party, (B) the Indemnified Party, at its sole cost and
      expense which shall not be included as part of the loss, damage or
      expense, including, without limitation, reasonable attorneys' and
      consultants' fees, suffered by it, may participate in the defense of such
      claim with co-counsel of its choice to the extent that the Indemnified
      Party believes in its sole discretion that such matter shall affect its
      ongoing business and (C) the Indemnifying Party shall not consent to the
      entry of any judgment with respect to the matter or enter into any
      settlement with respect to the matter which does not include a provision
      whereby the plaintiff or claimant in the matter releases the Indemnified
      Party from all liability with respect


                                      -15-

<PAGE>   16



      thereto. If, within such 30-day period, the Indemnifying Party does not
      assume the defense of such matter, the Indemnified Party may defend
      against the matter in any manner that it reasonably may deem appropriate
      and may consent to the entry of any judgment with respect to the
      matter or enter into any settlement with respect to the matter without the
      consent of the Indemnifying Party, subject to the right of the
      Indemnifying Party to contest its obligation to indemnify and hold
      harmless the Indemnified Party.

               (iv) Amount of Indemnification. The amount to which an
      Indemnified Party shall be entitled under this Section 6(b) shall be
      determined: (a) by the written agreement between the Indemnified Party and
      the Indemnifying Party; (b) by a final judgment or decree of any court of
      competent jurisdiction or (c) by any other means to which the Indemnified
      Party and the Indemnifying Party shall agree. The judgment or decree of a
      court shall be deemed final when the time for appeal, if any, shall have
      expired and no appeal shall have been taken or when all appeals taken have
      been finally determined.

      (c) Transaction Expenses. Except as otherwise provided herein, each of
Buyer and Seller shall bear his, her or its own costs and expenses incurred in
connection with this Agreement and the transactions contemplated hereby (whether
or not consummated).

      (d) Further Assurances. Seller shall execute and deliver such further
instruments of conveyance and transfer and take such additional action as Buyer
may reasonably request (including assisting Buyer in the collection of
receivables) to effect, consummate, confirm or evidence the transfer to Buyer of
the Acquired Assets, and Seller shall execute such documents as may be necessary
to assist Buyer in preserving or perfecting its rights in the Acquired Assets.

      (e) Confidentiality. Whether or not the transactions contemplated hereby
are consummated, Buyer and Seller shall keep confidential all information and
materials regarding the other party(ies) reasonably designated by such
party(ies) as confidential at the time of disclosure thereof. If the
transactions contemplated hereby are consummated, Seller shall maintain
confidential and shall not use or disclose, directly or indirectly (except as
required by law or as authorized in writing by Buyer


                                      -16-

<PAGE>   17



prior to such disclosure), any confidential or proprietary information or
materials regarding the other party.

      (f) Seller' Noncompete and Nonsolicitation.

                (i) In consideration of the Closing Date Payment, Seller hereby
      agrees that during the period beginning on the Closing Date and ending on
      the fifth anniversary of the Closing Date (the "Noncompete Period"), it
      shall not, directly or indirectly, either for itself or for any other
      Person, permit its name to be used by or Participate (as hereinafter
      defined) in any business located anywhere in the continent of North
      America or enterprise identical or similar to or competitive with the
      Business or Buyer's business. For purposes of this Section 6(f), the term
      "Participate" includes any direct or indirect interest in any enterprise,
      whether as an officer, director, stockholder, employee, partner, sole
      proprietor, agent, representative, independent contractor, consultant,
      franchisor, franchisee, creditor, owner or otherwise. Seller agrees that
      this covenant is reasonable with respect to its duration, geographical
      area and scope.

               (ii) During the Noncompete Period Seller shall not (A) induce or
      attempt to induce any employee of Buyer or its Affiliates to leave his or
      her employ or in any way interfere with the relationship between Buyer or
      its Affiliates and any of their respective employees or (B) induce or
      attempt to induce any supplier, licensee, licensor, franchisee, or other
      business relation of Buyer or its Affiliates to cease doing business with
      them or in any way interfere with the relationship between Buyer or its
      Affiliates and any customer or business relation.

              (iii) The parties hereto agree that Buyer may suffer irreparable
      harm from a breach by Seller of any of the covenants or agreements
      contained in this Section 6(f). In the event of an alleged or threatened
      breach by Seller of any of the provisions of this Section 6(f), Buyer or
      its successors or assigns may, in addition to all other rights and
      remedies existing in its favor, apply to any court of competent
      jurisdiction for specific performance and/or injunctive or other relief in
      order to enforce or prevent any violations of the provisions hereof
      (including the extension of the Noncompete Period by a period equal to the
      length of


                                      -17-

<PAGE>   18



      the violation of this Section 6(f)). In the event of an alleged breach or
      violation by Seller of any of the provisions of this Section 6(i), the
      Non-Competition Period shall be tolled until such alleged breach or
      violation is resolved. Seller agrees that these restrictions are
      reasonable.

               (iv) If, at the time of enforcement of any of the provisions of
      this Section 6(f), a court holds that the restrictions stated herein are
      unreasonable under the circumstances then existing, the parties hereto
      agree that the maximum period, scope or geographical area reasonable under
      such circumstances shall be substituted for the stated period, scope or
      area.

                (v) Seller agrees that the covenants made in Section 6(f)(i) and
      (ii) shall be construed as an agreement independent of any other provision
      of this Agreement and shall survive any order of a court of competent
      jurisdiction terminating any other provision of this Agreement.

      (g) Employees. Immediately after the Closing, all employees employed by
Seller immediately prior to the Closing shall become employees of Buyer on terms
and conditions substantially similar to their employment by Seller. Each such
employee shall be entitled to participate in all Buyer employee benefit and
employee welfare plans to the same extent as similarly situated employees of
Buyer (it being understood that each of Seller's employees shall be entitled to
prior service credit in respect of Buyer's vacation policy). When employed by
Buyer, all former employees of Seller shall be employees-at-will of Buyer and
nothing contained herein shall entitle any employee to remain in the employment
of Buyer or affect the right of Buyer to terminate any employee at any time.

      SECTION 7.        TERMINATION.  This Agreement may be terminated:

      (a) by mutual written consent of Buyer and Seller at any time
prior to the Closing; or

      (b) by Buyer or Seller, by giving written notice to the other party (the
"Nonterminating Party") at any time prior to Closing (i) in the event that the
Nonterminating Party has breached any representation, warranty or covenant
contained in this Agreement in any material respect, or (ii) if the Closing
shall not have occurred on or before December 31, 1996.
