part, in Dallas County, Texas and, in part, in the Philippines, and shall be
governed by and construed in accordance with laws of the State of Texas, U.S.A.,
without giving effect to any choice or conflict of law provision or rule
(whether of the State of Texas or any other jurisdiction) that would cause the
application of the laws of any jurisdiction other than the  State of Texas. The
United Nations Convention On Contracts For The International Sale Of Goods shall
not apply to this Agreement. The section headings contained in this Agreement
are for reference purposes only and shall not affect the meaning or
interpretation of this Agreement.

     16.7   Severability: If any term or provision of this Agreement or the
application thereof to any Person or circumstance shall be deemed invalid,
illegal or unenforceable to any extent or for any reason, such provision shall
be severed from this Agreement and the remainder of this Agreement and the
application thereof shall not be affected and shall be enforceable to the
fullest extent permitted by law.  A provision which is valid, legal and
enforceable shall be substituted for the severed provision.

     16.8   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, unless the context requires otherwise.

     16.9   Force Majeure:  Neither party shall be liable for loss or damage or
deemed to be in breach of this Agreement if its failure to perform its
obligations results from (i) compliance with any law, ruling, order, regulation,
requirement, or instruction of any federal, state, foreign, or municipal
government or any department or agency thereof; (ii) acts of God; or (iii)
fires, strikes, embargoes, war, or riot.  The party experiencing such cause or
delay shall immediately notify the other party of the circumstances which may
prevent or significantly delay its performance hereunder and shall use its best
efforts to alleviate the effects of such cause or delay.  Any delay resulting
from any of these causes shall extend performance accordingly or excuse
performance, in whole or in part, as may be reasonable.

     16.10  Counterparts.  This Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original and all of which
together shall be deemed to be one and the same instrument.

     16.11  Agency.  Contractor is an independent contractor.  Nothing in this
Agreement shall be construed to constitute either party the agent of the other
party and neither party shall represent to any third party that it has any right
or authority to act as the agent for or otherwise to represent the other party.

     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.
