7.   ADDITIONAL AGREEMENTS.
     --------------------- 

     Buyer and Sellers hereby covenant and agree with respect to certain matters
as follows:

      7.1 Returns; Indemnification; Liability for Taxes.  Buyer shall prepare
          ---------------------------------------------                      
and file (or cause to be prepared and filed) on a timely basis all Tax Returns
of the Company relating to periods ending prior to, on or after the Closing Date
and shall pay, and shall indemnify and hold Seller harmless against and from,
the following:  (i) all Taxes of the Company for any taxable year or period,
whether commencing prior to or after the Closing Date; and (ii) and transfer
Taxes payable by Buyer pursuant to Section 2.3 of this Agreement.

      7.2 Refunds and Credits.
          ------------------- 

          (a) All refunds or credits of Taxes for or attributable to any taxable
     years or periods of the Company shall be for the account of Buyer.
     Following the Closing, Seller shall forward (or cause to be forwarded) to
     Buyer any refunds due to Buyer pursuant to this section after receipt or
     realization thereof by Seller, in accordance with the provisions of
     subsection (b) below.

          (b) Any payments of refunds (including refunds attributable to
     credits) for Taxes required to be paid under this Agreement shall be made
     within ten business days of the receipt of any refund, as the case may be.
     Any payments not made within such time period, shall be subject to an
     interest charge of ten percent per annum.

      7.3 Conduct of Audits and Other Procedural Matters.  Buyer shall, at its
          ----------------------------------------------                      
own expense, control any audit or examination by any Tax Authority, and have the
right to initiate any claim for refund or amended return, and contest, resolve
and defend against any assessment, notice of deficiency or other adjustment or
proposed adjustment of Taxes ("Proceedings") for which Buyer is charged with
payment or indemnification responsibility under this Agreement.  Seller shall
promptly forward to Buyer in accordance with Section 10.7 all written
notifications and other written communications, including if available the
original envelope showing any postmark, from any Tax Authority received by
Seller or its Affiliates relating to any liability for Taxes for any taxable
period for which Buyer or any of its Affiliates is charged with payment or
indemnification responsibility under this Agreement.  Buyer shall promptly
notify, and consult with, Seller as to any action it proposes to take with
respect to any liability for Taxes for which it is required to indemnify Seller
and shall not enter into any closing agreement or final settlement with any Tax
Authority with respect to any such liability without the written consent of
Seller, which consent shall not be unreasonably withheld.  Seller shall, at the
expense of Buyer, execute or cause to be executed any powers of attorney or
other documents reasonably requested by Buyer to enable it to take any and all
actions that Buyer reasonably requests with respect to any Proceedings which
Buyer controls.  The failure by Seller to provide timely notice under this
subsection shall relieve the Buyer from its indemnification 

                                     -28-
<PAGE>
 
obligations under Section 7.2 with respect to the subject matter of any
notification not timely forwarded, to the extent Buyer has suffered a loss or
other economic detriment because of such failure to provide notification in a
timely fashion.

      7.4 Access to Records Following the Closing.  Until the expiration of the
          ---------------------------------------                              
applicable statutes of limitations for Tax matters, Buyer and Seller agree that
so long as any books, records and files of the Company retained by Seller or the
books records and files delivered to the control of Buyer pursuant to this
Agreement, to the extent they relate to the operations of the Company prior to
the Closing Date, remain in existence and available, each Party (at its expense)
shall have the right upon prior notice to make reasonable inspection and copies
of the same at any time during business hours for any proper purpose. Buyer and
Seller shall use reasonable efforts not to destroy or allow the destruction of
any such books, records and files without first offering in writing to deliver
them to the other.

      7.5 Payment of Company Liabilities, etc.
          ------------------------------------

          (a) Buyer hereby covenants and agrees with Seller that, at all times
     on and after the Closing, Buyer will cause the Company to promptly pay (or
     will itself promptly pay) or perform when due any and all Disclosed
     Liabilities (as defined below).  As used herein, the term "Disclosed
     Liabilities" means all Liabilities of the Company to any vendors, lessors
     and/or any other creditors that (i) existed at, or were incurred or arose
     on or prior to, the time and date of the Closing; and (ii) either (A) are
     reflected in the Most Recent Balance Sheet, (B) arise in the Ordinary
     Course of Business of the Company after the date of the Most Recent Balance
     Sheet or (C) arise under the terms of any agreement, contract or other
     commitment of the Company that is disclosed in either the Disclosure Letter
     or the Schedules. By way of illustration, but not limitation, the Disclosed
     Liabilities include, but are not limited to, any obligations for the
     payment of rent under leases and obligations for the payment of royalties
     or other payments due under licenses.  Notwithstanding the foregoing,
     "Disclosed Liabilities" will not include Liabilities for which Seller is
     obligated to indemnify Buyer under the provisions of Section 8 of this
     Agreement.

          (b) As of or immediately following the Closing, (i) Buyer will offer
     to guaranty all funded indebtedness of the Company reflected on the Most
     Recent Balance Sheet of which Seller is a guarantor, and (ii) Buyer will
     make best efforts to obtain the agreement of the payees of all such funded
     indebtedness to release Seller as a guarantor thereof.  In the event that
     Buyer is unable to remove Seller from any guarantee within six (6) weeks
     after the Closing Date, Buyer agrees to promptly pay the full amount of
     outstanding indebtedness under such guarantee and close the account so
     guaranteed at that time.

      7.6 Non-Solicitation of Company Employees.  For a period of one year
          -------------------------------------                           
beginning on the Closing Date, neither Seller nor any of Seller's directors,
officers, employees or Affiliates who are acting in such capacity on behalf of
Seller or any of his Affiliates, shall, without Buyer's prior written consent,
solicit, encourage or otherwise take any action intended to induce any
individual who is then an employee of the Company to terminate his or her
employment with the Company; provided however, that nothing herein will prevent
Seller or any of its Affiliates from hiring any employee of the Company who,
without any solicitation, encouragement or inducement by Seller or any of its
directors,  officers, employees or Affiliates, independently applies for
employment with Seller or any of its Affiliates.

     the Company to offer, employment to the former Company Agents identified on
     Schedule 7.7(a).  Such offer will be made to such former Company Agents at
     ---------------                                                           
     the annual salary levels set forth opposite their respective names on such
     Schedule 7.7(a).  The other terms and conditions of employment offered to

     such persons shall be substantially the same as the terms and conditions of
     employment applicable to Buyer's employees generally.

          (b) Following the Closing, Buyer will undertake to make available to

          (a) Subject to the terms and conditions of this Agreement, Seller
     hereby agrees to indemnify, defend and hold harmless Buyer and Buyer's
     directors, officers and Affiliates (which includes the Company and its
     officers, directors and Affiliates after the Closing) against and in
     respect of all Loss(es) incurred or reasonably determined in good faith by
     Buyer to be incurred by Buyer, or its directors, officers and Affiliates,
     or asserted against them to the extent that such Loss(es) arises from a
     Breach by Seller as provided in Section 8.1; provided, however, that Buyer

     asserting Buyer's claim for indemnification for such actual or reasonably

     claim for indemnification under Section 8.3(c) below.

          (b) In the event of a pending or threatened action that includes
     asserted claims which, if assumed to be true, would entitle Buyer or any of
     its directors, officers or Affiliates to indemnification under Section
     8.3(a), Buyer shall give prompt written notice of such action or actions to
     Seller, and Seller shall be entitled to control the defense and
     negotiation, if any, regarding settlement of such action or actions, at
     Seller's expense (including the cost of any such settlement itself), and
     Buyer shall cooperate with Seller, at Seller's expense, in the compromise
     or defense of any such action or actions, provided that, in such event, (i)

     to or enter into any settlement of such action or actions without Seller's
     prior written consent, which consent shall not be unreasonably withheld,

                                     -32-
<PAGE>
 
     and/or (ii) Seller shall not agree to or enter into any settlement that
     requires cessation of Buyer's use or other similar restrictions on use of,
     any of the Company Assets without the written consent of Buyer.

          (c) In order for Buyer, Buyer's directors, officers or Affiliates to
     be indemnified in accordance with Section 8.3(a)  above, any claim for
     indemnification made by Buyer or any of Buyer's directors, officers and
     Affiliates under this Agreement  must be set forth in an Officer's
     Indemnification Certificate of Buyer that is delivered to Seller.  (The
     Parties agree that there is no limit on the dollar amount of
     indemnification to which Buyer may become entitled to pursuant to this
     Section 8.3.).   No claim for indemnification; (i) that is not an Extended
     Buyer Claim may be made, raised or asserted in any manner by Buyer or any
     director, officer or Affiliate of Buyer, or any of their permitted
     successors or assigns unless such claim for indemnification hereunder is
     set forth in an Officer's Indemnification Certificate of Buyer that is
     delivered to Seller prior to the expiration of the Survival Period; or (ii)
     that is an Extended Buyer Claim may be made, raised or asserted in any
     manner by Buyer or any director, officer or Affiliate of Buyer, or any of
     their permitted successors or assigns, unless such claim for
     indemnification hereunder is set forth in an Officer's Indemnification
     Certificate of Buyer that is delivered to Seller prior to the expiration of
     the applicable legal statute of limitations regarding such Extended Buyer
     Claim.

          (d) Except for any rights of specific performance under applicable
     law, the rights of indemnification afforded to Buyer and its directors,
     officers and Affiliates under the foregoing provisions of this Section 8.3
     shall constitute the sole and exclusive right and remedy of Buyer and its
     directors, officers and Affiliates with respect to any Breach by Seller.

          (e) Notwithstanding anything herein to the contrary, neither Buyer nor
     any of its directors, officers or Affiliates shall be entitled to any
     indemnification of any claim from Seller under this Agreement unless and
     until the aggregate amount of Loss(es) for which indemnification would
     otherwise be available from Seller under this Section 8.3 exceeds an
     aggregate of $20,000 (the "Seller's Basket"), after which time Buyer and
     its directors, officers and Affiliates will be entitled, subject to the
     terms and conditions of this Section 8, to recover any and all Loss with
     respect to which Buyer is entitled to indemnification pursuant to Section
     8.3(a) above; provided, however, that claims for indemnification that are
     Extended Buyer Claims shall not be subject to the above provisions of this
     subsection (e) regarding Seller's Basket.

      8.4 Indemnity by Buyer.
          ------------------

     hereby agrees to indemnify, defend and hold harmless Seller, Seller's
     Affiliates and those persons who were the directors and officers of the
     Company immediately prior to the Closing (the "Company Directors and
     Officers") against and in respect of all Loss(es) incurred by or asserted
     against them to the extent that such Loss(es) arises from a Breach by Buyer
     as provided in Section 8.1; provided, however, that Seller delivers to
     Buyer an Officer's Indemnification Certificate of Seller asserting Seller's
     claim for indemnification for such actual or reasonably expected Loss(es)
     on or before the applicable deadline for asserting such claim for
     indemnification under Section 8.4(c) below.

          (b) In the event of a pending or threatened action that includes
     asserted claims which, if assumed to be true, would entitle Seller or any
     of its Affiliates or any of the Company Directors 

                                     -33-

     and Officers to indemnification under Section 8.4(a), Seller shall give
     prompt written notice of such action or actions to Buyer, and Buyer shall
     be entitled to control the defense and negotiation, if any, regarding
     settlement of such action or actions, at Buyer's expense (including the
     cost of any such settlement itself), and Seller shall cooperate with Buyer,
     at Buyer's expense, in the compromise or defense of any such action or
     actions, provided that, in such event, neither Seller nor any director,
     officer or Affiliate of Seller shall agree to or enter into any settlement
     of such action or actions without Buyer's prior written consent, which
     consent shall not be unreasonably withheld.

          (c) In order for Seller, Seller's directors, officers or Affiliates or
     the Company Directors and Officers to be indemnified in accordance with
     Section 8.4(a) above, any claim for indemnification made by Seller, any of
     Seller's Affiliates or any of the Company Directors or Officers under this
     Agreement must be set forth in an Officer's Indemnification Certificate of
     Seller that is delivered to Buyer.  No claim for indemnification:  (i) that
     is not an Extended Seller Claim may be made, raised or asserted in any
     manner by Seller, any Affiliate of Seller, any of the Company Directors or
     Officers or any of their permitted successors or assigns, unless such claim
     for indemnification is set forth in an Officer's Indemnification
     Certificate that is delivered to Buyer prior to termination of the Survival
     Period; or (ii) that is an Extended Seller Claim (except as set forth in
     the following item (iii)) may be made, raised or asserted in any manner by
     Seller, any Affiliate of Seller, any of the Company Directors or Officers
     or any of their permitted successors or assigns, unless such claim for
     indemnification hereunder is set forth in an Officer's Indemnification
     Certificate of Seller that is delivered to Buyer prior to the expiration of
     the applicable legal statute of limitations regarding such Extended Seller
     Claim; except that (iii) a claim for indemnification that is an Extended
     Seller Claim related to Section 7.5 (Payment of Company Liabilities) may be
     brought at any time.

          (d) Except for any rights of specific performance under applicable
     law, the rights of indemnification afforded to Seller, Seller's directors,
     officers and Affiliates or any of the Company Directors and Officers under
     the foregoing provisions of this Section 8.4 shall constitute the sole and
     exclusive right and remedy of Seller and its Affiliates and the Company
     Directors and Officers with respect to any Breach by Buyer.

          (e) Notwithstanding anything herein to the contrary, neither Seller
     nor any of its Affiliates nor any of the Company Directors or Officers
     shall be entitled to any indemnification of any claim from Buyer under this
     Agreement unless and until the aggregate amount of Loss(es) for which
     indemnification would otherwise be available from Buyer under this Section
     8.4 exceeds an aggregate of $5,000 (the "Buyer's Basket"), whereupon Seller
     and its directors, officers and Affiliates and the Company Directors and
     Officers will be entitled to recover any and all Loss(es) with respect to
     which Seller is entitled to indemnification pursuant to Section 8.4(a)
     above; provided, however, that claims for indemnification that are Extended
     Seller Claims shall not be subject to the above provisions of this
     subsection (e) regarding Buyer's Basket.

      8.5 Resolution of Conflicts; Arbitration.
          ------------------------------------ 

          (a) In case Seller or Buyer shall object in writing to any claim or
     claims made by Buyer or Seller, as the case may be, in any Officer's
     Indemnification Certificate, Seller and Buyer shall attempt in good faith
     to agree upon the rights of the respective parties with respect to each 

                                     -34-
<PAGE>
 
     of such claims. If Seller and Buyer should so agree, a memorandum setting
     forth such agreement shall be prepared and signed by both parties.

          (b) If no such agreement of Buyer and Seller can be reached after good
     faith negotiation, either Buyer or Seller may demand arbitration of the
     matter in accordance with this Agreement unless the amount of the Loss is
     at issue in pending litigation with a third party, in which event
     arbitration shall not be commenced until such amount is ascertained or both
     parties agree to arbitration, whichever is earlier; and in either such
     event the matter shall be settled by arbitration conducted by a single
     arbitrator acceptable to both Buyer and Seller in accordance with the
     commercial arbitration rules of the American Arbitration Association as
     modified by this Agreement.  The arbitrator shall set a limited time period
     and establish procedures designed to reduce the cost and time for discovery
     while allowing the parties an opportunity, adequate in the sole judgement
     of the arbitrator, to discover relevant information from the opposing
     Parties about the subject matter of the dispute.  The arbitrator shall rule
     upon motions to compel or limit discovery and shall have the authority to
     impose sanctions, including attorneys' fees and costs, to the same extent
     as a court of competent law or equity, should the arbitrators determine
     that discovery was sought without substantial justification or that
     discovery was refused or objected to without substantial justification.
     The decision of the arbitrator as to the validity and amount of any claim
     in such Officer's Certificate shall be binding and conclusive upon the
     Parties to this Agreement.  Such decision shall be written and shall be
     supported by written findings of fact and conclusions which shall set forth
     the award, judgment, decree or order awarded by the arbitrator.

          (c) Judgment upon any award rendered by the arbitrator may be entered
     in any court having jurisdiction.  Any such arbitration shall be held in
     Los Angeles County, California under the Rules of the American Arbitration
     Association.  The arbitrator shall determine how all expenses relating to
     the arbitration shall be paid, including without limitation, the respective
     expenses of each Party.

          (d) The foregoing arbitration provisions shall apply to any dispute
     arising under or relating to this Agreement.

inure to the benefit of the parties named herein and their respective successors
and permitted assigns. No Party may assign either this Agreement or any of its

           -------------                                                       
accordance with the laws of the State of California without giving effect to any
choice or conflict of law provision or rule of any other jurisdiction whatsoever
that would cause the application of the laws of any jurisdiction other than the
State of California.

      10.9 Amendments and Waivers.  No amendment of any provision of this
           ----------------------                                        
Agreement shall be valid unless the same shall be in writing and signed by Buyer
and Sellers.  No waiver by any Party of any default, misrepresentation or breach
of warranty or covenant hereunder, whether intentional or not, shall be deemed
to extend to any prior or subsequent default, misrepresentation or breach of
warranty or covenant hereunder or affect in any way any rights arising by virtue
of any prior or subsequent such occurrence.

      10.10 Severability.  Any term or provision of this Agreement that is 
            ------------        
invalid or unenforceable in any situation in any jurisdiction shall not affect
the validity or enforceability of the remaining terms and provisions hereof or
the validity or enforceability of the offending term or provision in any other
situation or in any other jurisdiction.

      10.11 Construction.  The Parties have participated jointly in the

negotiation and drafting of this Agreement.  In the event an ambiguity or
question of intent or interpretation arises, this Agreement shall be construed
as if drafted jointly by the Parties and no presumption or burden of proof shall
arise favoring or disfavoring any Party by virtue of the authorship of any of
the provisions of this Agreement.  Any reference to any federal, state, local or
foreign statute or law shall be deemed also to refer to all rules and
regulations promulgated thereunder prior to the Closing, unless the context
requires  otherwise.  The word "including" shall mean including without
limitation.  Nothing in the Schedules hereto shall be deemed adequate to
disclose an exception to a representation or warranty made herein unless the
Schedule identifies the exception with reasonable particularity and describes
the relevant facts in reasonable detail.  The Parties intend that each
representation or warranty and covenant contained herein shall have independent
significance.  If any Party has breached any representation, warranty or
covenant contained herein in any respect, the fact that there exists another
representation, warranty or covenant relating to the same subject matter
(regardless of the relative levels of specificity) which the Party has not
breached shall not detract from or mitigate the fact that the Party is in breach
of the first representation, warranty or covenant.
