to the Raw Inventory (as defined below) of the Business to the Purchaser for a
period of at least ninety (90) days from the Closing Date. During such period,
such Raw Inventory shall remain on the Company's premises and the Purchaser
shall be entitled, but without obligation, and from time to time, to draw down

where conducted by Purchaser. During such ninety (90) day period, the purchase
price to be paid by the Purchaser for such Raw Inventory shall be sixty percent
(60%) of the lower of the Company's cost or the market price of such Raw

Purchaser shall be entitled to purchase all or part of the remaining Raw
Inventory in bulk for a price and upon terms to be negotiated by the parties at

down of any such Raw Inventory. Following the expiration of such ninety (90) day
period, the Purchaser shall be entitled to purchase all or part of the remaining
Raw Inventory at a price and upon terms to be negotiated by the parties at such
time; provided that, if the parties are unable to negotiate a mutually
acceptable price at which such remaining Raw Inventory may be purchased by the
Purchaser, then the Company may sell any Raw Inventory after the expiration of
such ninety (90) day period to any third party other than the Purchaser. For
purposes hereof, the term "Raw Inventory" shall mean all inventory used in the
Business which is not Work-in-Process Inventory (as defined in Section I(a)(v)
above).

        (f) Allocation. The Purchase Price for the Assets shall be allocated to

Purchaser and attached hereto within twenty one (21) days from the date hereof
and the Purchaser agrees to file Internal Revenue Service Form 8594 which shall

facilities located at 185 Monmouth Parkway, West, Long Branch, New Jersey 07764
and 46360 Fremont Boulevard, Fremont, California 94538 (the "Facilities").
Purchaser shall have full access and all rights of the Company to the
Facilities; provided, however, that the Purchaser hereby agrees that it shall
reimburse the Company for that portion of the rent and expenses paid by the
Company with respect to the Facilities, which are


                                      -4-
<PAGE>   5


allocable to the portions of the Facilities used exclusively by the Purchaser to
store the Assets. This Section I(g) does not constitute a lease or sublease, and
nothing contained in this Section I(g) or elsewhere in this Agreement shall be
construed as subjecting Purchaser to or obligating Purchaser under any of the
terms and conditions of the leases relating to the Facilities and Purchaser
shall incur no liability in connection with such leases.

        (h) Loan Amount. The Purchaser may, but shall not be obligated to, loan
money to the Company directly, or indirectly by participating in any loans made
to the Company by IBJ Schroeder Bank & Trust Company. Any such amount loaned by
the Purchaser to the Company, either directly or indirectly, shall be referred
to herein as the "Loan Amount."

the Company has not sold and


                                      -5-

shall seek from the Bankruptcy Court an order (the "Overbid Procedures Order")
providing for the procedure for the parties to follow in the event that the
Company receives, in writing, any offer or proposal relating to the sale of the
Assets other than the transactions contemplated by this Agreement (a "Competing
Proposal"). The Company agrees that the Overbid Procedures Order shall provide,
among other things, the following:

               (i) The Bankruptcy Court will not consider any Competing Proposal
unless the Competing Proposal (a) provides for a purchase price consideration
for the Assets of at least One Hundred Percent (100%) of the aggregate
consideration being paid by the Purchaser hereunder, plus the topping fee of
Four Hundred Fifty Thousand Dollars ($450,000) described in Section IV(c)(vii)

Proposal on a timely basis and to operate the Business or the Assets on a
financially viable basis, (d) is made by a person who has completed its due
diligence review of the Company's books and records, and is satisfied with the
results thereof, (e) is made by a person who is obligated to pay an initial

purchase price payable to the Company, and (f) the Competing Proposal is
delivered to the Company and filed with the Bankruptcy Court at least two (2)
court days prior to the Motion Date. A Competing Proposal that satisfies the
foregoing criteria shall be referred to as a "Qualifying Competing Proposal."

               (ii) At the hearing on the Motion Date, only the Purchaser and
any party who has submitted a Qualifying Competing Proposal shall be entitled to
bid.

               (iii) At the hearing on the Motion Date, the Bankruptcy Court
shall decide which of the bids are the highest and best bid, and such bid shall
be deemed to be the "High Bid." The bidder whose bid is definitively deemed by
the Bankruptcy Court to be the High Bid must pay all amounts reflected in the
High Bid in cash at the Closing.

               (iv) If the Purchaser's bid is not the High Bid, then the
Purchaser shall be entitled to match the High Bid and the Purchaser's matching
bid shall be deemed to be the High Bid.

               (v) Thereafter, bidding will be conducted as ordered by the
Bankruptcy Court with the Purchaser always entitled to meet and match the other
bids, and if the Purchaser matches another higher bid, its bid will be declared
the successful High Bid.

$25,000 higher than the prior bid or counterbid. For purposes hereof, the
topping fee payable to the Purchaser pursuant to Section IV(c)(vii) shall be
credited to the Purchaser as part of its bid.

               (vii) If the Company terminates this Agreement because the
Purchaser's bid is not the High Bid, regardless of whether or not the Company
consummates a transaction with the successful bidder, then the Purchaser shall
be delivered a topping fee equal to Four Hundred Fifty Thousand Dollars
($450,000), which fee shall be paid within five (5) days of the date of such
termination and shall be paid solely from the deposit paid by the successful
bidder as part of such successful bidder's Qualifying Competing Proposal,
without any administrative liability therefor to the estate.

                                    SECTION V

        (a) Post Closing Cooperation. In case at any time after the Closing any
further action is necessary or desirable to carry out the purposes of this
Agreement, each of the parties will take such further action (including the
execution and delivery of such further instruments and documents) as the other
may request, all at the sole cost and expense of the requesting party (unless
the requesting party is entitled to indemnification therefor under Section
VIII), so long as such documents do not increase the liability or risk of
liability of the party of whom action is requested.

        (b) Discharge of Obligations. Consistent with and subject to an order of
the Bankruptcy Court, the Company covenants and agrees to pay promptly and
otherwise to fulfill and discharge all of the Liabilities of the Company arising
from and after the filing of the Bankruptcy Case, when due and payable and
otherwise prior to the time at which any of such Liabilities could in any way
result in or give rise to a claim against the Assets, the Business or the
Purchaser, result in the imposition of any lien, charge or encumbrance on any of
the Assets, or adversely affect the Purchaser's title to or use of any of the
Assets.

        (c) Access. The Company shall give to the Purchaser and its
representatives, from and after the date of execution of this Agreement, on
prior reasonable request therefor from the Purchaser or such representatives,
such access to the premises, employees, agents and consultants of the Company,
and such copies of the Financial Statements, books and records, and contracts
and leases and other documentation, so as to enable the Purchaser to inspect and
evaluate all aspects of the Business and operations, assets, operating results,
financial condition, capitalization, ownership, and legal affairs thereof. This
shall include the right of the Purchaser to have Phase I environmental
evaluations conducted on the any real property owned or leased by the Company in
connection with the Business, at the Purchaser's sole expense. The Purchaser
agrees to conduct its review, and to cause its representatives to conduct their
review, in a manner designed to minimize any disruption of the operations of the
Company.

        (d) Conduct of Business. From the date of this Agreement and until the
Closing or termination of this Agreement, whichever first occurs, the Company
shall use commercially reasonable best efforts, consistent with prior practice
(a) to preserve intact the business organization and employees and other
business relationships relating to the Business, (b) to continue to operate in


                                      -7-

the ordinary course of its business and to maintain its books, records and
accounts in accordance with GAAP and (c) to preserve and maintain the Assets,

directly or indirectly (a) offer to sell any of the Business and/or the Assets
(other than sales of inventory in the ordinary course of the Business), in whole
or in part, (b) make or assist anyone else to make any proposal to purchase any
of the Business and/or the Assets (other than sales of inventory in the ordinary
course of the Business), (c) encourage, solicit or initiate discussions or
negotiations with any corporation, partnership, person, entity or group, other
than the Purchaser, concerning any merger, consolidation, sale of assets, sale
of securities or acquisition of beneficial ownership with respect to the
Business, or (d) otherwise initiate any action (unless in response to an
unsolicited offer) which would prejudice the ability of the Purchaser to
complete the transactions described in this Agreement; provided, however, that
notwithstanding the foregoing, nothing set forth in this Section V(e) shall
prohibit or limit in any way, the Company's ability to notify (including by
means of advertisement) any corporation, partnership, person, entity or group of
(1) the contents of the Overbid Procedure Order, (2) their ability to submit a
Qualifying Competing Proposal, (3) the procedures to be followed when submitting

with its corporate policy considered on a consolidated basis, and in a manner
consistent with Purchaser's consolidated strategy, policies, practices and
resources.

which is fourteen (14) days prior to the Motion Date, the Purchaser shall

currently has no actual knowledge of any condition precedent to the obligations
of the Purchaser to consummate the purchase of the Assets which has not been
fulfilled as of such date other than such conditions which are not to be
fulfilled until after such date or (ii) the conditions precedent to the
obligations of the Purchaser to consummate the purchase of the Assets which were
required to be fulfilled, but which have not been fulfilled, as of such date.
The delivery of such notice by the Purchaser shall in no way limit or otherwise
affect the Purchaser's ability to terminate this Agreement pursuant to the
provisions of Section X(a) in the event that there has been a failure of any

of which shall be deemed an original, but all of which taken together shall
constitute one and the same instrument.

        (j) Accounts Receivable and Business Records. From and after the

in the collection by Company of the Company's Accounts Receivable. Any and all
books and records which may be deemed part of the Assets shall be made available
at no cost to the Company, upon reasonable prior notice and during normal
business hours, in connection with the collection by Company of its Accounts
Receivable and for any other valid business purpose. None of the business
records that constitute part of the Assets shall be destroyed by Purchasers
without the written consent of Company. The obligations set forth in this
subparagraph shall survive Closing. Without limiting the foregoing, the
Purchaser shall be entitled to collect and retain all accounts receivable
attributable to the sales of inventory purchased by the Purchaser hereunder, or
otherwise sold by the Purchaser after the Closing Date (such receivables shall
be deemed "Purchaser Receivables").
