unanimous affirmative vote of all Directors or the unanimous written consent of
all Directors, and the approval of the PRC original Approving Authority. Except
as otherwise set forth in Article 6.3.2, in the case of such Transfer by a Party

WEIHAI BARRINGTON, the other Parties (the "Non-transferring Parties") shall have
a right of first refusal with respect to such interests to be transferred at the

(a "Notice of Transfer"), describing the portion of equity interest proposed to
be Transferred (the "Subject Interest"), the name or names of the proposed
transferee(s), if any, and the consideration proposed to be paid therefor (and,
to the extent the consideration does not consist of cash, the US dollar
equivalent thereof reasonably determined by an independent appraiser who is
acceptable to the Non-transferring Party) (the "Subject Consideration"). Such
Notice of Transfer shall constitute an option to the Non-transferring Parties to
purchase all, but not less than all, of the Subject Interest for the Subject
Consideration and on the terms and conditions as set forth in the Notice of
Transfer. The Non-transferring Parties may exercise the option by giving a
written notice of such exercise to the Transferring Party within ninety (90)
days after receipt of the Notice of Transfer. The notice of exercise shall set
forth a closing date, which may be any date from thirty (30) to sixty (60) days
after all relevant approvals to the Transfer have been obtained. If no notice of
exercise is given by the Non-transferring Parties within the ninety-day option
period, the Transferring Party may, only upon the consent of the other Parties,
following the expiration of such ninety-day option period (or such prior time as
the Non-transferring Parties shall have, in writing, advised the Transferring
Party of their election not to exercise the right of the first refusal),
transfer all (but not less than all) of the Subject Interest at no less than the
Subject Consideration and on the terms and conditions to the proposed
transferee(s) as provided in the Notice of Transfer. This Article 6.3 shall not
apply in the circumstances contemplated by Articles 16.2 or 17.8.

hereby gives consent to any Transfer by the other Parties of all or any of its
equity interest in WEIHAI BARRINGTON to an Affiliate of the Transferring Party
(a "Permitted Transfer"), and waives its preemptive right to purchase the other
Parties' interest which is transferred to such Affiliate. Such consent shall be
valid throughout the term of this Contract. The Transferring Party shall notify
the other Parties not less than thirty (30) days in advance of any such
Permitted Transfer, and each Party shall cause its appointed directors to the
Board to approve such Permitted Transfer and support the Transferring Party in
its application to the Approval Authority for approval of such Permitted
Transfer.

     6.3.3 Any Transfer of any Party's equity interest under this Article shall
not become effective until all necessary approvals have been obtained.

     6.3.4 Upon Transfer of the registered capital of a Party, WEIHAI BARRINGTON
shall cancel the then outstanding capital contribution certificates of the
Transferring Party and issue new capital contribution certificates to the
transferee to reflect the new ownership interests (and if the Transferring Party
Transfers only a portion of its equity interest to the transferee, a new capital
contribution certificate shall also be issued to the Transferring Party
reflecting its remaining equity interest in WEIHAI BARRINGTON), and
simultaneously therewith the transferee shall execute an instrument pursuant to
which it shall become a party to and be bound by this Contract and the Articles
of Association, as amended as of such Transfer.

assets of WEIHAI BARRINGTON, shall be distributed to the Parties valued at their
respective fair market value, on a pro rata basis according to the proportion of
registered capital of WEIHAI BARRINGTON contributed by the respective Parties.
As between the Parties, Party A agrees that Party B shall have the first
priority with respect to any remaining foreign exchange assets of WEIHAI
BARRINGTON to the extent of its prevailing percentage share of profits. The
liquidation plan shall provide that both Parties will have the right to purchase
any of WEIHAI BARRINGTON's machinery, equipment and other facilities acquired by
WEIHAI BARRINGTON after the Business License Date. In the event the Parties
offer the same terms and conditions for any such purchases, Party A shall have
priority.

     17.5.2 To the extent any of the amounts distributed to the Foreign Parties
are distributed in RMB, Party A agrees that it will:

          (a) assist the Foreign Parties in exchanging RMB for foreign currency
at the most favorable rate possible in the PRC; and/or

          (b) assist the Foreign Parties in obtaining approval from the relevant
PRC government authorities and purchasing in RMB, at the most favorable prices
possible, products acceptable to the Foreign Parties which the Foreign Parties
shall be free to export from the PRC.

Article 17.6 - Public Announcement
----------------------------------

          Upon completion of the liquidation, WEIHAI BARRINGTON shall present a
report to the original PRC Approving Authority or their successors, complete the
formalities for canceling WEIHAI BARRINGTON's registration at the Weihai
Municipal Administration of Industry and Commerce, surrender its business
license and, at that time, make a public announcement of its liquidation,
termination and winding-up. The announcement should be published three(3) times
constantly on the newspaper not lower than provincial grade.

Article 17.7 - Records
----------------------

          After WEIHAI BARRINGTON has ceased doing business, all records shall
be kept by Party A. And copies will be provided to the other parties upon
request.

Article 17.8 - Retained Rights
------------------------------

          Termination of this Contract shall not prejudice the accrued rights
and liabilities of the Parties at the date of termination, unless otherwise
waived in writing by such Party or Parties, as the case may be.

Article 17.9 - Purchase of WEIHAI BARRINGTON Interests Upon Termination
-----------------------------------------------------------------------

     17.9.1 If upon termination of this Contract and the terms of Article 16.2
are not otherwise applicable, any Party wishes to purchase from the other
Parties the equity interests in WEIHAI BARRINGTON it does not already own, such
Party shall notify the other Parties of such intention. The fair-market price of
such equity interests in WEIHAI BARRINGTON shall be determined by an
internationally recognized appraisal or merchant banking firm chosen by the
Liquidation Committee, the calculation of which price shall be substantiated in
a written report. In any such case, the price for which such interests may be
sold shall not be less than the value determined by such firm, unless otherwise
agreed by the Parties.

     17.9.2 If upon termination of this Contract, no Party has elected to
exercise its rights under Article 17.9.1 to purchase from the other Parties the
equity interests in WEIHAI BARRINGTON it does not already own (and Article 16.2

<PAGE>

JOINT VENTURE CONTRACT TO ESTABLISH WEIHAI BARRINGTON              Page 26 of 32

is not otherwise applicable), assuming the Liquidation Committee decides to
conduct a public auction or a private sale of WEIHAI BARRINGTON, such sale shall
be effected in accordance with the terms and procedures set by the Liquidation
Committee for such public auction or private sale, provided that any Party may
participate in such auction or private sale if the minimum price paid by such
Party is no less than the value determined by the appraisal or merchant banking
firm as set forth in Article 17.9.1.

Article 17.10 - Liquidation Under Certain Circumstances
-------------------------------------------------------

          Notwithstanding the foregoing provisions of this Chapter, in case this
Contract is terminated prior to its expiration by reason of Articles 16.1.1,
16.1.2, or 16.1.3, where no Party or third party purchases the Equity Interests
of the other Party, or all Equity Interests in US CHINA MEDICAL pursuant to this
Contract are terminated prior to its expiration by reason of Articles 16.1.4,
16.1.5, 16.1.6, 16.1.7 or 16.1.8, and the non-breaching Parties do not elect to
acquire the breaching Party's interest pursuant to Article 16.2(a), each of the
Parties, after ensuring the US China Medical pay up all its liabilities and
expenses, shall cooperate and shall cause US CHINA MEDICAL to promptly return to
each Party its capital contributions in the form, currency and amount
contributed to US CHINA MEDICAL by such Party, to the extent contributions are
available, and as to a breaching Party pursuant to Article 16.2, only after
payment of all damages to the non-breaching Parties pursuant to Article 16.2(b).
All remaining assets shall be distributed to the Parties on a pro rata basis
according to Article 14.2 hereof. The Parties each guarantee, and the
Liquidation Committee is bound to effect, that any remaining foreign exchange
balance of US CHINA MEDICAL upon its liquidation or dissolution shall be first
applied to the settlement of Party B's pro rata share of the remaining assets.

                              CHAPTER 18. INSURANCE

          The Parties shall cause WEIHAI BARRINGTON to be covered, at WEIHAI
BARRINGTON's expense, by appropriate insurance policies underwritten by the
People's Insurance Company of China or any other registered insurance company
authorized to provide the relevant insurance in the PRC on the basis of the most
competitive price, coverage and other relevant terms, provided, however, that
such policies shall be competitive internationally with respect to premiums,
coverage, and service as determined and agreed to by the Board.

                            CHAPTER 19. FORCE MAJEURE

Article 19.1 - Force Majeure
----------------------------

     19.1.1 "Force Majeure" shall mean any of the following: acts by government
or public agency, riot, war, hostility, strikes, epidemics, fire, flood,
earthquake, storm, tidal wave or other acts of nature, and all other events
beyond the control of the Parties or WEIHAI BARRINGTON which are not
foreseeable, or, if foreseeable, are unavoidable.

     19.1.2 If one Party has been prevented from performing its responsibilities
stipulated in this Contract because of an event of Force Majeure, it shall
notify the other Parties in writing within fourteen (14) days after the
occurrence of such Force Majeure and shall act to mitigate damages. If an event
of Force Majeure occurs, no Party shall be liable for any damage, increased
costs or losses that another Party may sustain by reason of such failure or
delay in performance. In the event of Force Majeure, the Parties shall
immediately consult with each other in order to find an equitable solution and
shall use all reasonable endeavors to minimize the consequences of such Force
Majeure. The Party claiming Force Majeure shall take appropriate measures to
mitigate or remove the effects of Force Majeure and, within the shortest
possible time, resume as soon as possible the Contract performance affected by
the event of Force Majeure.

Centre.

     22.1.3 In making their decisions, the arbitrators shall be bound by the
intention of the Parties insofar as such can be ascertained from the JV
Contract, its Appendices, the Articles of Association and, where no such
intention can be ascertained, by the generally accepted standards and principles
of international law and customary international practice as they have been
applied by international tribunals in dispute resolutions. The arbitrators may
refer to both of the English and Chinese texts of this Contract, its Appendices
(whether in English, Chinese or both), and the Articles of Association.

     22.1.4 The language to be used in the arbitration proceedings shall be
Chinese, with English translation. The arbitrators shall render a written
opinion in Chinese to support their decision.

     22.1.5 The arbitration decision made by the arbitration tribunal under this
Chapter shall be final and binding upon both Parties. The Parties shall use
