and Johnson  have not  entered  into,  and they agree none will enter into,  any
agreement either written or oral in conflict herewith.

        (b)  Consultant  understands  as  part  of  the  consideration  for  its
continued  retention  by Company,  that Drs.  Sheu,  Liang and Johnson  have not
brought  and  will  not  bring  to  Company  or use in  the  performance  of the
responsibilities hereunder any materials or documents of a former employer which
are not generally  available to the public,  unless they have  obtained  written

                                       9

authorization from the former employer for their possession and use.

        (c) In the event  that  prior to  entering  this  Consulting  Agreement,
Consultants  terminated  employment  with  one  or  more  prior  employers,  the
Consultant  agrees  to  indemnify  and hold  harmless  Company,  its  directors,
officers and employees,  against any liabilities and expenses, including amounts
paid in settlement,  incurred by any of them in connection with any claim by any
of Drs. Sheu,  Liang and Johnson's prior employers that the termination of their
individual employment with such employer, their employment by Consultant, or use
of any skills and  knowledge by Company is a violation of contract or law. On or
prior to the date  hereof,  Consultant  has  delivered  to Company a copy of any
contract of employment  between Drs. Sheu, Liang and Johnson and each such prior
employer.

     12. Specific Performance.  The Consultant acknowledges that its obligations
and the  obligations of Consultants  hereunder are unique,  and that it would be
extremely impracticable to measure the resulting damages if he should default in
its obligations under this Agreement.  Accordingly,  in the event of the failure
by Consultant to perform its obligations hereunder,  which failure constitutes a
breach hereof by him, the Company may, in addition to any other available rights
or remedies,  sue in equity for specific  performance of each of the Consultants
and, in connection  with any such suit,  the  Consultant  and  Consultants  each
expressly  waives the defense therein that the Company has an adequate remedy at
law.

     13.  Interpretation.  It is the desire and intent of the  parties  that the
provisions of this Agreement shall be enforced to the fullest extent permissible
under  the  laws and  public  policies  applied  in each  jurisdiction  in which
enforcement  is  sought.  Accordingly,  if  any  particular  provision  of  this
Agreement  shall be adjudicated to be invalid or  unenforceable,  such provision
shall be deemed amended to delete there from the portion thus  adjudicated to be
invalid  or  unenforceable,  such  deletion  to apply  only with  respect to the
operation  of such  provision  in the  particular  jurisdiction  in  which  such
adjudication  is  made.  In  addition,  if any  one or  more  of the  provisions
contained in this Agreement shall for any reason be held to be excessively broad
as to duration,  geographical scope,  activity or subject, it shall be construed
by limiting and  reducing it so as to be  enforceable  to the extent  compatible
with the applicable law as it shall then appear.

     14. Entire Agreement;  Modification; Waiver. This Agreement constitutes the
entire agreement between the parties  pertaining to the subject matter contained
in it and supersedes all prior agreements,  representations  and  understandings
between the parties. No supplement,  modification or amendment of this Agreement
shall be binding unless executed in writing by both parties. No waiver of any of
the  provisions  of this  Agreement  shall be deemed to, or shall  constitute  a
waiver of, any other  provisions,  whether or not similar,  nor shall any waiver
constitute a continuing  waiver.  No waiver shall be binding unless  executed in
writing by the party making the waiver.

     15.  Notices.  All  notices,  requests,  demands  or  other  communications
required or desired to be given  hereunder shall be in writing and shall be sent
by registered or certified mail, with return receipt  requested,  with a copy by
facsimile  transmission  to the  following  address  (or as  the  parties  shall
otherwise direct in writing):

transactions  contemplated  hereby  or  thereby  shall be  resolved  by  binding
arbitration. The arbitration shall be conducted by a single arbitrator who shall
administer  the  arbitration  under  the  then  current  commercial  rules.  The
arbitration  shall take place in Los  Angeles,  California.  The parties  hereto
irrevocably  submit to the exclusive  jurisdiction  of such entity.  The parties
hereby irrevocably waive, to the fullest extent permitted by applicable law, any
objection  which  they may now or  hereafter  have to the laying of venue of any
such  dispute  brought in such venue or any  defense  of  inconvenient  forum in
connection therewith.

     18.   Counterparts.   This  Agreement  may  be  executed  in  one  or  more
counterparts,  each of which be deemed an original,  but all of which when taken
together shall constitute one and the same Agreement.

     19. Non-Assignability. This agreement shall not be assignable by Consultant
or  Consultants  without  the  express  written  consent  of the  Company.  This
Agreement supersedes any and all written and oral agreements between the parties
hereto.
