                       ARONS' OBLIGATIONS AFTER CLOSING

         Section 8.1 Arons' General Release. Arons, for himself and his legal
successors and assigns, effective upon the Closing, hereby settles, releases,
waives and absolutely discharges the Company and its successors, assigns,
incorporators, stockholders, officers, directors, agents, employees,
accountants, attorneys, past, present and future, and any of their heirs,
executors, administrators, successors or assigns (together, for purposes of this
Section 8.1, the "Released Parties"), from all claims, damages, liabilities,
costs, expenses, obligations and causes of action, in each case of every kind
and nature, whether now known or unknown, suspected or unsuspected, which
involve or relate to Arons' ownership of any of the Shares or Options, or his
employment by the Company, including, without limitation, any claim relating to
any federal or state securities law violation by or common law liability for
fraud or neglect or other misrepresentation of any of the Released Parties
arising by reason of any purported misstatement or omission of a material fact,
whether written or oral, or the management or conduct of the business and
affairs of the Company, excepting only the obligations of Company arising under
this Agreement (together, for purposes of this Section 8.1, the "Released
Matters").

                  Arons waives and relinquishes any right or benefit which he
has or may have under Section 1542 of the Civil Code of the State of California
or any similar provision of the statutory or nonstatutory law of any other
jurisdiction to the full extent they may lawfully waive such rights and benefits
pertaining to the subject matter of this Agreement. Section 1542 of the
California Civil Code reads:

                     "A GENERAL RELEASE DOES NOT EXTEND TO
                     CLAIMS WHICH THE CREDITOR DOES NOT
                     KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT
                     THE TIME OF EXECUTING THE RELEASE, WHICH
                     IF KNOWN BY HIM MUST HAVE MATERIALLY


                                       8

<PAGE>

                     EFFECTED HIS SETTLEMENT WITH THE DEBTOR."

                  In connection with such waiver and relinquishment, Arons
acknowledges that he is aware that he or his attorneys or others may hereafter
discover claims or facts in addition to or different from those which Arons now
knows or believes to exist with respect to the subject matter of this Agreement,
that it is Arons' intention to fully, finally and forever release, waive and
discharge all of the Released Matters. The release given herein shall remain in
effect as a full and complete general release, notwithstanding the discovery or
existence of any such additional or different claims or facts.

costs, expenses, obligations, liabilities, damages, causes of action, recoveries
and deficiencies, including interest, penalties and reasonable attorneys' fees
that Arons shall incur or suffer, which directly or indirectly arise, result

to perform any of its representations, warranties, covenants or agreements in
this Agreement or in any schedule, certificate, exhibit or other instrument
furnished or to be furnished by the Company under this Agreement; and (b) any
claim against Arons asserting or alleging liability for any act or failure to
act, or breach of any duty as an officer, director, shareholder, employee,
agent, fiduciary or other representative of Company, including but not limited
to any claim in the nature of a shareholder or other derivative claim, whether
or not any such claim is determined to be meritorious; and (c) any claim against
Arons asserting or alleging liability for entering into or performing under this
Agreement, whether or not such claim is determined to be meritorious. Arons
shall have the right but not the obligation to join, participate in and control,
if he so elects, any legal proceeding or action for which Arons is entitled to
indemnification under this Section. All costs and expenses incurred by Arons for
which Company is responsible under this Section or for which Arons is entitled
to indemnification shall be reimbursed to Arons on demand. The provisions of
this Section 9.1 shall be in addition to and not in limitation of the rights to
indemnification and insurance provided under Article IX of Company's bylaws, all
of which rights hereby are confirmed to Arons.

         Section 9.2 Company's General Release. The Company, for itself and its
legal successors and assigns, effective upon the Closing, hereby settles,

excepting only the obligations of Arons arising under this Agreement (together,
for purposes of this Section 9.2, the "Released Matters").

         The Company waives and relinquishes any right or benefit which it has
or may have under Section 1542 of the Civil Code of the State of California or
any similar provision of the statutory or non-statutory law of any other
jurisdiction to the full extent it may lawfully waive such rights and benefits
pertaining to the subject matter of this Agreement. Section 1542 of the
California Civil Code reads:

                      EFFECTED HIS SETTLEMENT WITH THE
                      DEBTOR."

         In connection with such waiver and relinquishment, the Company
acknowledges that it is aware that it or its attorneys or others may hereafter
discover claims or facts in addition to or different from those which the
Company now knows or believes to exist with respect to the subject matter of
this Agreement, that it is the Company's intention to fully, finally and forever
release, waive and discharge all of the Released Matters. The release given

or amendment of this Agreement shall be binding unless executed in writing by
all the parties. Any party may waive any term, provision or condition included
for the benefit of such party. No waiver of any of the provisions of this

                                      12
<PAGE>

waiver constitute a continuing waiver. No waiver shall be binding unless
executed in writing by the party making the waiver.

         Section 11.3 Counterparts. This Agreement may be executed
simultaneously in one or more counterparts, each of which shall be deemed an
original, but all of which together shall constitute one and the same

         Section 11.4 Severability. If any provision of this Agreement, as
applied to any party or to any circumstance, shall be found by a court to be

documentation subsidiary to it.

Section 1 of this Agreement are true and accurate and are incorporated herein
at length.

                                 ARTICLE XII.
                                    PARTIES

         Section 12.1 Parties-in-Interest. Except as hereafter provided, nothing
in this Agreement, whether express or implied, is intended to confer any rights
or remedies under or by reason of this Agreement on any persons other than the
parties to it and their respective successors and assigns, nor is anything in
this Agreement intended to relieve or discharge the obligation or

                                      13

<PAGE>

liability of any third persons to any party to this Agreement, nor shall any
provision give any third persons any right of subrogation or action against any
party to this Agreement. The parties to this Agreement do understand, expect and
intend that Third Party Investors in the Company will rely upon the warranties,
representations and covenants of the parties contained in this Agreement in
determining whether or not to invest in the Company, and such Third Party
Investors are intended beneficiaries under this Agreement.

         Section 12.2 Binding Effect. This Agreement shall be binding on, and
shall inure to the benefit of, the parties to it and their respective heirs,
legal representatives, successors, and assigns.

                                   REMEDIES

         Section 13.1 Specific Performance and Waiver of Rescission Rights.
Arons' and the Company's obligations under this Agreement are unique. If Arons
or the Company should default in their or its obligations under this Agreement
prior to the Closing, the parties each acknowledge that it would be extremely
impracticable to measure the resulting damages; accordingly, in addition to any
other available rights or remedies, Arons and the Company may sue in equity for
specific performance, and Arons and the Company expressly waive the defense that
a remedy in damages will be adequate. Notwithstanding any breach or default by
any of the parties of any of their respective representations, warranties,
covenants or agreements under this Agreement, if the purchase and sale
contemplated by it shall be consummated at the Closing, each of the parties
waives any rights that it or they may have to rescind this Agreement or the
transaction consummated by it; provided, however, this waiver shall not affect
any other rights or remedies available to the parties under this Agreement or
under law.

         Section 13.2 Recovery of Litigation Costs; Place of Litigation or
Arbitration. If any legal action or any arbitration or other proceeding is
brought for the enforcement of this Agreement, or because of an alleged
dispute, breach, default, or misrepresentation in connection

                                      14

<PAGE>

with any of the provisions of this Agreement, the successful or prevailing party
or parties shall be entitled to recover reasonable attorneys' fees and other
costs incurred in that action or proceedings, in addition to any other relief to
which it or they may be entitled. Any litigation or arbitration shall occur
exclusively in Los Angeles County, California.

         Section 13.3 Defaults Permitting Termination. If prior to the Closing
Arons or the Company materially default in the due and timely performance of any
of its or his warranties, covenants, or agreements under this Agreement, a
nondefaulting party may give notice of termination of this Agreement, in the
manner provided in Section 15.1. This notice shall specify with particularity
the default or defaults on which the notice is based. The termination shall be
effective on the later of five (5) days after the giving of such notice or the
Closing, unless the specified default or defaults have been cured on or before
the effective date for termination.

         Section 13.4 Arbitration. In order to obtain prompt and expeditious
resolution of any disputes under this Agreement, the parties hereby agree that
each claim, dispute or controversy, of whatever nature, arising out of, in
connection with, or in relation to the interpretation, performance or breach of
this Agreement (or any other agreement contemplated by or related to this
Agreement) including without limitation any claim based on contract, tort or
statute, or the arbitrability of any claim hereunder (an "Arbitrable Claim"),
shall be settled by final and binding arbitration conducted in Los Angeles
County, California under the auspices of and in accordance with the Commercial
Arbitration Rules then in effect of the American Arbitration Association. Each
party hereto expressly consents to, and waives any future objection to, such
forum and arbitration rules. Judgment upon any award may be entered by any state
or federal court having jurisdiction thereof.
