allocate sufficient Manufacturing capacity for the Manufacture of Products to
meet Company's Production and Shipping Dates, and all Material acquired by
Contractor to meet Company's Production and Shipping Dates will be covered by
the Buy-Back provisions of this Agreement. Company agrees to supply Materials,
including Die, a minimum of one day prior to the associated starts at the

Materials inventory purchased by Contractor should Company fail to Order
forecasted quantities based on 100% of forecasted Materials for the three month
period and such failure to Order is in no way attributable to Contractor.  The
Company will not be required to buy back any Materials beyond the third month of
the twelve (12) month forecast. Notwithstanding the above, Contractor will
attempt to divert Materials to other manufacturing uses so as to minimize this
excess inventory cost to Company.

then in any such event, Company shall have the right to decline to take further
deliveries hereunder or Company may, without prejudice to any other lawful
remedy, cancel this Agreement, and in either case, Contractor shall upon demand
deliver to Company all Provided Equipment, Materials, WIP Inventory, Finished
Goods, tooling and other property of Company in Contractor's custody.  If during
the term of this Agreement a petition in bankruptcy is filed by or against
Company, or if Company, as a debtor, seeks or takes the benefit of any
insolvency or debtor's relief proceeding, or if Company shall file an assignment
for the benefit of creditors, or if Company applies to its creditors to compound
its debts, then in any such event, Contractor may without prejudice to any other
lawful remedy, cancel this Agreement.

     16.13  Assignment of Obligations.  Neither party may assign this Agreement
without the prior written consent of the other party; provided that Company may
assign this Agreement to any Person acquiring all or substantially all of
Company's assets.

     16.14  Export & Import Laws/Regulations.  The parties shall comply with all
applicable Philippines and International Export and Import laws and regulations
in the execution of this Agreement.  Contractor shall execute such other
agreements and documents as Company requests, from time to time, in order to
ensure compliance with said laws.

     16.15  Dispute Resolution.

            (a)  Negotiation. In the event of any dispute or disagreement
between parties as to the interpretation of any provision of this Agreement (or
the performance of obligations hereunder), the matter, upon written request of
either party, shall be referred to representatives of the parties for decision,
each party being represented by a senior executive officer who has no direct
operational responsibility for the matters contemplated by this Agreement. The
representatives shall promptly meet in a good faith effort to resolve the
dispute. If the representatives do not agree upon a decision within 30 calendar
days after reference of the matter to them, each of the parties shall be free to
exercise all other remedies available to it.

            (b)  Arbitration. Any controversy, dispute or claim arising out of
or relating in any way to this Agreement or the other agreements contemplated
hereby or the transactions arising hereunder or thereunder that cannot be
resolved by negotiation pursuant to paragraph (a) above shall, be settled
exclusively by binding arbitration in Hong Kong and in accordance with the
current Commercial Arbitration Rules of the International Chamber of Commerce.
The parties shall endeavor to select a mutually acceptable arbitrator
knowledgeable about issues relating to the subject matter of this contract. In
the event the parties are unable to agree upon an arbitrator, each party will
select an arbitrator and the arbitrators in turn shall select a third
arbitrator. The language of the arbitration will be in English. The fees and
expenses of the arbitrator shall be shared equally by the parties and advanced
by them from time to time as required; provided that at the conclusion of the
arbitration, the arbitrator may award costs and expenses (including the costs of
the arbitration previously advanced and the fees and expenses of attorneys,
accountant and other experts) plus interest, to the prevailing party to the
extent that in the judgment of the arbitrator it is fair to do so. No pre-
arbitration discovery shall be permitted, except that the arbitrator shall have
the power in his or her sole discretion, on application by any party, to order
pre-arbitration examination solely of those witnesses and documents that any
other party intends to introduce in its case-in-chief at the arbitration
hearing. The arbitrator shall render his or her award within 90 days of the
conclusion of the arbitration hearing. Notwithstanding anything to the contrary
provided in this Section 16.15 and without prejudice to the above procedures,
either party may apply to any court of competent jurisdiction for temporary
injunctive or other provisional judicial relief if such action is necessary to
avoid irreparable damage or to preserve the status quo until such time as the
arbitration panel is convened and available to hear such party's request for
temporary relief. The award rendered by the arbitrator shall be final and not
subject to judicial review and judgment thereon may be entered in any court of
competent jurisdiction. Any monetary award will be made and payable in U.S.
dollars free of any tax or other deduction.

    16.16   English Controlling. For purposes of convenience, this Agreement may
be translated but it is understood that the English version of this Agreement
(and the schedules and exhibits) will control for all purposes.
