which have arisen subsequent to the Closing Date.

                                    AGREEMENT

         NOW THEREFORE, in consideration of the above recitals, and of the
mutual covenants contained herein, and other good and valuable consideration,
the receipt and adequacy of which are hereby acknowledged by the parties hereto,
the parties agree as follows:

         1.       Defined Terms. Capitalized terms used but not otherwise

Agreement.

         2.       Agreement. Pinnacle agrees to pay Two Million Dollars
($2,000,000) (the "NET ADJUSTMENT PAYMENT") to SCM within five business days

as satisfaction and final settlement of each matter provided for below in this
Section 2.

                  (a)      Realization Shortfall. Notwithstanding anything in
Section 2.12(d) of the Purchase Agreement to the contrary, Pinnacle agrees to
remit any Realization Shortfall due to SCM pursuant to Section 2.12(d) of the
Purchase Agreement on or before December 29, 2003.

                  (b)      Inventory, Backlog and Receivables. Upon Pinnacle's

otherwise under the Purchase Agreement; and (iii) Pinnacle shall be discharged
and released from its obligation to assist Seller in the collection of
Receivables, as provided by Section 5.13 of the Purchase Agreement; and all fees

against SCM's Receivables and shall not interfere with SCM's continued
collection of such Receivables. SCM shall have no authority to issue any
credits, rebates or offsets against Pinnacle's Receivables, and shall not

from such customers.

                  (c)      Dell. Pinnacle acknowledges that it assumes SCM's
warranty obligation to Dell, Inc. in its entirety pursuant to that certain
Master Purchase Agreement by and between Sub and Dell, Inc., dated December 1,
2000 (the "DELL AGREEMENT"), and SCM shall have no further warranty obligation
to Dell pursuant to the Dell Agreement, which assumption has been taken into
account in the determination of the Net Adjustment Payment.

                  (d)      Transition Services Agreement. The parties hereby
agree that upon Pinnacle's remittance of the Net Adjustment Payment to SCM all
amounts owed SCM pursuant to the Transition Services Agreement by and between
Parent and Pinnacle, dated July 25, 2003, and the Transition Services Schedules
attached thereto (collectively, the "TRANSITION SERVICES AGREEMENT"), shall be
deemed paid in full and all of SCM's obligations pursuant to the Transition
Services Agreement shall cease and be deemed to have been fully discharged.

                  (e)      Product Returns. Notwithstanding the provisions of
Section 5.14 of the Purchase Agreement, the Net Adjustment Payment shall be
deemed to satisfy any payments that otherwise would be due from Pinnacle to SCM
in respect of Product Returns, provided that:

                           i.       Promptly after the execution of this
         Agreement, the parties shall issue a joint letter to all Distribution
         Channel Participants, which letter shall instruct such Distribution
         Channel Participants that all inquiries or requests regarding the
         Transferred Products (including but not limited to inquiries and
         requests regarding warranty obligations), and all returns of
         Transferred Products, should be directed to Pinnacle from the date of
         the letter going forward.

                           ii.      Pinnacle shall accept any and all bona fide
         warranty returns from end-users or Distribution Channel Participants
         for any Transferred Products sold by SCM prior to the Closing Date, and
         shall issue a credit against that Distribution Channel Participant's
         account with Pinnacle or a refund, to be determined by Pinnacle in its
         sole discretion.

                           iii.     Pinnacle shall accept any and all
         non-warranty returns by a Distribution Channel Participant, for any
         Transferred Products sold by SCM prior to the Closing Date ("STOCK
         RETURNS"). If the aggregate value of the Stock Returns after the date
         hereof for any Distribution Channel Participant is less than or equal
         to Ten Thousand Dollars ($10,000) (whether in one or more Stock Return
         requests), Pinnacle shall issue a credit against that Distribution
         Channel Participant's account with Pinnacle or a refund, to be
         determined by Pinnacle in its sole discretion. If the aggregate value
         of the Stock Returns for

         any Distribution Channel Participant exceeds Ten Thousand Dollars
         ($10,000) (whether in one or more Stock Return requests), Pinnacle
         shall notify SCM of such Stock Return request and transmit the request
         for a Return Manufacturer's Authorization ("RMA") for such Stock
         Returns to SCM, and SCM shall be solely responsible, for its own
         account, for any credit or refund that may be due to such Distribution
         Channel Participant.

                           iv.      Pinnacle and SCM agree not to take any
         affirmative steps to suggest, promote, or otherwise encourage any Stock
         Returns, and in the event any Stock Returns arise that may be
         attributable to any such activities, then the parties shall undertake
         to reach a separate agreement regarding how to address such Stock
         Returns, such agreements to be made on a case by case basis.

                           v.       Pinnacle may retain all Transferred
         Products, whether opened or unopened, returned to it or to SCM by a
         Distribution Channel Participant. In the event that Pinnacle shall so
         elect to retain any such Transferred Products returned to SCM, SCM
         shall clearly mark all such Transferred Products returned to it so that
         they can be identified by Pinnacle's packers, and Pinnacle shall be
         responsible for packing, crating and shipping all such Transferred
         Products returned to SCM, and for any transportation costs.

                  (f)      Solectron. SCM hereby acknowledges that it remains
responsible for any and all obligations owed to Solectron Technology Sdn Bhd
pursuant to those certain Purchase Order Numbers 5000004708 and 5000004716.

                  (g)      Sound Vision. Pinnacle acknowledges that it has
assumed responsibility for all changes that are or may be required with respect
to any and all Sound Vision products, and that SCM shall have no further
obligation to Sound Vision or to Pinnacle with respect to such products, which
assumption has been taken account in the determination of the Net Adjustment
Payment.

         3.       Mutual Release. Provided that the Net Adjustment Payment is
paid to SCM within five business days after the date hereof, then as of the date
hereof, Pinnacle and SCM, along with their respective affiliates, subsidiaries,
attorneys, insurers, reinsurers, predecessors, successors, directors, officers,
parents, subsidiaries, employees and assigns, release and forever discharge each
other and their respective affiliates, subsidiaries, attorneys, insurers,
