        6.4 Entire Agreement. This Agreement, together with the Exhibits annexed
hereto, contains the entire understanding among the parties hereto concerning
the subject matter hereof and this Agreement may not be changed, modified,
altered or terminated except by an agreement in writing executed by the parties
hereto. Any waiver by any party of any of its rights under this Agreement or of
any breach of this Agreement shall not constitute a waiver of any other rights
or of any other or future breach.

        6.5 Remedies Cumulative. Except as otherwise provided herein, each and
all of the rights and remedies in this Agreement provided, and each and all of
the rights and remedies allowed at law and in equity in like case, shall be
cumulative, and the exercise of one right or remedy shall not be exclusive of
the right to exercise or resort to any and all other rights or remedies provided
in this Agreement or at law or in equity.

        6.6 Governing Law. This Agreement shall be construed in accordance with
and subject to the laws and decisions of the State of New York applicable to
contracts made and to be performed entirely therein.

        6.7 Counterparts. This Agreement may be executed in several counterparts
hereof, and by the different parties hereto on separate counterparts hereof,
each of which shall be an original; but such counterparts shall together
constitute one and the same instrument.

        6.8 Waivers. No provision in this Agreement shall be deemed waived
except by an instrument in writing signed by the party waiving such provision.

        6.9 Successors and Assigns. This Agreement shall be binding upon and
inure to the benefit of the parties hereto and to their respective successors
and assigns; provided, however, that except as otherwise expressly set forth in
this Agreement neither the rights nor the obligations of either party may be
assigned or delegated without the prior written consent of the other parties.

        6.10 Further Assurances. The Investor shall, at the request of the
Company, and the Company shall, at the request of the Investor, from time to
time, execute and deliver such other assignments, transfers, conveyances and
other instruments and documents and do and perform such other acts and things as
may be reasonably necessary or desirable for effecting complete consummation of
this Agreement and the transactions herein contemplated.

        6.11 Disclosures.

            (a) Confidentiality. Each of the Investor and the Company
acknowledges and confirms in connection with the negotiation of this Agreement
and the execution hereof, during the period from the date hereof through the
Closing Date, the parties hereto will have furnished to one another certain
materials, information, data and other documentation ("Disclosures")




                                       13
<PAGE>   16
concerning their business, financial condition and operations which are
proprietary and confidential. Each party acknowledges the party disclosing such
Disclosures considers them secret and confidential and asserts a proprietary
interest therein. Accordingly, each of HTL and the Investor, on the one hand,
and the Company, on the other hand, covenants and agrees that it shall maintain
all Disclosures made by the other party in strict confidence and shall not use
such Disclosures for its own benefit or disclose them to third parties, except
to its agents, representatives, bankers, investment bankers, counsel and
employees involved in evaluating the transactions contemplated by this
Agreement, its partners (and the partners or other security holders thereof) or
as otherwise required by law (including the requirement of the Company to
disclose such terms under the Securities Act, the Exchange Act or under the
rules of any securities exchange on which the securities of the Company are
registered; and including the requirement of the Investor to disclose such terms
under the securities laws of the United States or Hong Kong, as applicable, or
under the rules of the Hong Kong Stock Exchange or NASDAQ).

            (b) Public Announcements. No public announcement by any party hereto
with regard to the transactions contemplated hereby or the material terms hereof
shall be issued by any party without the mutual prior consent of the other
parties, except that in the event the parties are unable to agree on a press
release and legal counsel for one party is of the opinion that such press
release is required by law and such party furnishes the other party a written
opinion of outside legal counsel, or other counsel reasonably acceptable to the
party being furnished such opinion, to that effect, then such party may issue
the legally required press release.

            (c) Non-Confidential Information. This Agreement shall not restrict
any party hereto from using information already known to it, to which it is
entitled under existing agreements, or information generally in the public
domain or any information coming into its possession after it becomes public
knowledge unless it became public knowledge through a breach of this Agreement.

        6.12 Termination.

            (a) Events Triggering Termination. This Agreement may be terminated
and the transactions contemplated hereby may be abandoned, without further
obligation of the Company, HTL or the Investor, at any time prior to the Closing
Date as follows:

                (i) by mutual written consent duly authorized by the boards of
directors of the Company, HTL and the Investor; or

                (ii) by the Company, HTL or the Investor if the Closing Date
shall not have occurred on or before December 31, 1997 or such later date, if
any, as the Company, HTL and the Investor shall agree in writing; provided that
the party exercising such right is not in default of its obligations under this
Agreement in a manner which results in the failure to satisfy the conditions to
the transactions contemplated hereby of the other parties; or




                                       14
<PAGE>   17
                (iii) by the Company, HTL or the Investor if the consummation of
the transactions contemplated hereby shall be prohibited by a final,
non-appealable order, decree or injunction of a court of competent jurisdiction.

             (b) No Further Obligation. In the event of a termination of this
Agreement, no party hereto shall have any liability or further obligation to any
other party to this Agreement except that nothing herein will relieve any party
from liability for any breach of this Agreement.

        6.13 Jurisdiction; Consent to Service of Process. The Investor hereby
irrevocably appoints United Corporate Services, Inc., at its office at 10 Bank
Street, White Plains, New York 10606, United States of America, and the Company
hereby irrevocably appoints United Corporate Services, Inc., at its office at 10
Bank Street, White Plains, New York 10606, United States of America, its lawful
agent and attorney to accept and acknowledge service of any and all process
against it in any action, suit or proceeding arising in connection with this
Agreement, and upon whom such process may be served, with the same effect as if
such party were a resident of the State of New York and had been lawfully served
with such process in such jurisdiction, and waives all claim of error by reason
of such service, provided, however that in the case of any service upon such
agent and attorney, the party effecting such service shall also deliver a copy
thereof to the other party at the address and in the manner specified in SECTION
6.03. In the event that such agent and attorney resigns or otherwise becomes
incapable of acting as such, such party will appoint a successor agent and
attorney in New York, reasonably satisfactory to the other party, with like
powers. Each party hereby irrevocably submits to the exclusive jurisdiction of
the United States District Court for the Southern District of New York and any
court of the State of New York located in the City of New York in any such
action, suit or proceeding, and agrees that any such action, suit or proceeding
shall be brought only in such court (and waives any objection based on forum non
conveniens or any other objection to venue therein), provided, however, that
such consent to jurisdiction is solely for the purpose referred to in this
SECTION 6.13 and shall not be deemed to be a general submission to the
jurisdiction of said courts or the State of New York other than for such
purpose.


        IN WITNESS WHEREOF, the parties hereto have duly executed this Agreement
as of the date first above written.
