employees on matters pertaining to the business and affairs of the Company and
its subsidiaries, including, but not limited to, customer relations, customer
retention and business development. Consultant shall be required to devote no
more than fifteen (15) hours per week, employing reasonable energy, skill, and
efforts to perform such duties and to promote the Company's interests as is
required for the fulfillment of his obligations and the performance of his
duties under this Agreement.

         3. NONCOMPETITION COVENANT.3.1 AGREEMENT NOT TO COMPETE. During the
Term, and for a period of three (3) years thereafter, Consultant shall not,

partner, officer, director, stockholder, employee, member of any association or
otherwise) in any phase of the Business (the "RESTRICTED BUSINESS"); or (ii)
solicit or accept any Restricted Business from any customer to which the Company

                  6.1 TERM. The term of the consulting services to be provided
hereunder shall be a period of one (1) years commencing on the date hereof and
ending on October 15, 2004 (the "TERM").

                  6.2 TERMINATION. This Agreement may not be terminated by the
Company. Should Yang die during the Term, his heirs shall remain subject to the
confidentiality and non-compete covenants set forth in this Agreement and shall

         7. CONFIDENTIALITY.

                  7.1 Consultant shall not, at any time after the date hereof,
except with the express prior written consent of the Company, directly or
indirectly, disclose, communicate or divulge to any Person, or use for the
benefit of any Person, any secret, confidential or proprietary knowledge or
information with respect to the conduct or details of the Business including,
but not limited to, technical know-how, software, processes, customers,
prospects, costs, designs, marketing methods and strategies, finances and
suppliers.

                  7.2 The parties agree that any breach of the covenants and
agreements contained in this Section 7 shall result in irreparable injury to the
Company for which money damages could not adequately compensate the Company.
Therefore, in the event of any such breach, the Company shall be entitled (in
addition to any other rights and remedies which it may have at law or in equity)
to have an injunction issued by any competent court of equity enjoining and
restraining Consultant and/or any other Person involved therein from continuing
such breach. In any action to enforce the provisions of this Section 7,
Consultant and/or any other person involved therein shall expressly waive the
defense that the Company's remedy at law is adequate. The existence of any claim
or cause of action which Consultant may have against the Company or any other
Person (whether under this Agreement or otherwise) shall not constitute a
defense to or bar the enforcement of any of the covenants or agreements
contained in this Section 7. If the Company is obliged to resort to the courts
for the enforcement of any of the covenants or agreements contained herein, or
if such covenants or agreements are otherwise the subject of litigation between
the parties, then the term of such covenants and agreements shall be extended
for a period of time equal to the period of such breach.

                  7.3 If any portion of the covenants or agreements contained in
this Section 7, or the application thereof, is construed to be invalid or
unenforceable, then the other portions of such covenant(s) or agreement(s) or
the application thereof shall not be affected and shall be given full force and
effect without regard to the invalid or unenforceable portions. If any covenant
or agreement herein is held to be unenforceable because of the area covered, the
duration thereof, or the scope thereof, then the court making such determination
shall have, for purposes of enforcement in equity, the power to reduce the area
and/or duration and/or limit the scope thereof, and the covenant or agreement
shall then be enforceable in its reduced form.
