including but not limited to, meals,  supplies and materials.  Consultant shall,
at the  Contractor's  expense,  travel  to  such  locations  as  are  reasonably
specified by the Contractor for the purposes hereunder;  provided, however, that
each such  expense for which the  Contractor  shall be  responsible  for must be
agreed to by the Contractor prior to the time at which it is incurred.  Further,
arrangements  for  providing  Consultant's  transportation  and lodging for such
trips  shall  be made by the  Contractor  in  advance.  During  such  trips  the

available to the Consultant.

      SECTION 6. INDEPENDENCE OF CONTRACTOR.  The Contractor agrees that neither

      SECTION 11. TRADE SECRETS AND CONFIDENTIAL INFORMATION.  During the course
of  Consultant's  engagement  with the  Contractor,  the Contractor may disclose
Trade Secrets and Confidential  Information  (defined below) to Consultant.  The
Trade Secrets and the  Confidential  Information  of the Contractor are the sole
and  exclusive  property  of the  Contractor  (or a third party  providing  such
information  to the  Contractor).  The  disclosure  of the Trade Secrets and the
Confidential  Information  of the  Contractor  to  Consultant  does not give the
Consultant  any  license,  interest  or  rights  of any kind in or to the  Trade
Secrets or Confidential Information.

            (a)   Consultant   may  use  the  Trade  Secrets  and   Confidential
Information solely for the benefit of the Contractor while Consultant is engaged
as a Consultant  for the  Contractor.  Consultant  shall hold in confidence  the
existence of this Agreement and the Contractor's  engagement of Consultant,  the
Trade Secrets and  Confidential  Information  of the  Contractor.  Except in the
performance of services for the Contractor,  Consultant shall not use, disclose,
reproduce,  distribute,  transmit, reverse engineer, decompile,  disassemble, or
transfer the Trade Secrets or the Confidential  Information of the Contractor or
any portion thereof.

            (b) Consultant represents that Consultant is not presently under any
contract  or  agreement  with any  party  that  would  prevent  Consultant  from
performing his duties under this  Agreement,  and that Consultant is not subject
to or in breach of any  agreement,  including any  agreements  concerning  Trade
Secrets or Confidential  Information  owned by any other party.  Consultant also
agrees that during the course of  Consultant's  engagement,  Consultant will not
use or  disclose  any  confidential  information  or trade  secrets of any other
entity  or  third-party   unless   authorized  in  writing  by  that  entity  or
third-party.

            (c) The  obligations  under this  Agreement with regard to the Trade
Secrets  of  the  Contractor  remain  in  effect  as  long  as  the  information
constitutes a trade secret under  applicable law. The obligations with regard to
the  Confidential  Information  of the  Contractor  shall remain in effect while
Consultant  is engaged by the  Contractor  in any  capacity  and for a period of
three (3) years thereafter.

            (d)  Consultant  agrees  to  return  to  the  Contractor,  upon  the
termination of Consultant's  engagement (for any reason), or upon request by the
Contractor, the Trade Secrets and Confidential Information of the Contractor and
all materials relating thereto.

            (e)  As  used  herein,  "Trade  Secrets"  means  information  of the
Contractor, and its licensors,  suppliers, clients and customers, without regard
to  form,  including,  but not  limited  to,  technical  or  nontechnical  data,
formulas,  patterns,  compilations,   programs,  devices,  methods,  techniques,
drawings,  processes,  financial data, financial plans, product plans, or a list
of actual or potential customers or suppliers, which is not commonly known by or
available to the public and which information (i) derives economic value, actual
or  potential,  from  not  being  generally  known  to,  and not  being  readily
ascertainable  by proper means by, other persons who can obtain  economic  value
from  its  disclosure  or use and  (ii)  is the  subject  of  efforts  that  are
reasonable under the  circumstances to maintain its secrecy.  Trade Secrets also
include any information described in this paragraph which the Contractor obtains
from another party and which the Contractor  treats as proprietary or designates
as trade secrets,  whether or not owned or developed by the Contractor.  As used
herein, "Confidential Information" means information,  other than Trade Secrets,
that  possesses  an  element  of value to the  Contractor,  that is  treated  as
confidential,  and that would  potentially  damage the  Contractor if disclosed.

                                       3
<PAGE>

Confidential  Information  includes,  but is not limited to, (i) future business
plans,  (ii) the  composition,  description,  schematic  or design of  products,
future products or equipment of the  Contractor,  (iii)  communication  systems,
system designs and related  documentation,  (iv) advertising or marketing plans,
(v)  information  regarding  employees,  independent  contractors,  clients  and
customers  of the  Contractor,  (vi)  information  concerning  the  Contractor's
financial structure and methods and procedures of operation, and (vii) the terms
and conditions of this  Agreement.  Confidential  Information  also includes any
information  described  in this  paragraph  which the  Contractor  obtains  from
another party and which the  Contractor  treats as  proprietary,  whether or not
owned or  developed  by the  Contractor.  Confidential  Information  need not be
marked or stamped "confidential" to qualify as such under this Agreement.

      SECTION 12. WORK PRODUCT.  All Work Product  (defined  below) shall be the
exclusive  property of the  Contractor.  If any of the Work  Product may not, by
operation of law or  otherwise,  be  considered  the  exclusive  property of the
Contractor,  or if  ownership  of all right,  title,  and  interest to the legal
rights  therein  shall  not  otherwise  vest   exclusively  in  the  Contractor,
Consultant  hereby  assigns  to the  Contractor,  and upon the  future  creation
thereof automatically assigns to the Contractor,  without further consideration,
the ownership of all Work Product. The Contractor shall have the right to obtain
and hold in its own  name  copyrights,  patents,  registrations,  and any  other
protection available in the Work Product.  Consultant will promptly disclose any
and all such Work Product to Contractor. Consultant agrees to perform, during or
after  termination of  Consultant's  engagement by the  Contractor,  and without
requiring  Contractor  to provide  any  further  consideration  therefore,  such
further acts as may be  necessary  or desirable to transfer,  perfect and defend
the Contractor's ownership of the Work Product as requested by the Contractor.

      For purposes of this Agreement, "Work Product" shall mean all discoveries,
designs, Trade Secrets,  Confidential Information,  trademarks, data, materials,
formulas,  research,  documentation,  computer programs,  communication systems,
audio  systems,   system  designs,   inventions  (whether  or  not  patentable),
copyrightable  subject  matter,  works  of  authorship,  and  other  proprietary
information  or work product  (including  all  worldwide  rights  therein  under
patent, copyright,  trademark,  trade secret,  confidential  information,  moral
rights and other property  rights),  which Consultant has made or conceived,  or
may make or conceive,  either  solely or jointly with  others,  while  providing
services to  Contractor  or with the use of the time,  material or facilities of
Contractor or relating to any of  Contractor's  actual or  anticipated  business
known  to  Consultant  while  engaged  by the  Contractor,  or  suggested  by or
resulting  from any task assigned to Consultant or work  performed by Consultant
for or on behalf of Contractor.

      SECTION 13. TERMINATION OF ENGAGEMENT.

            (a) This Agreement shall terminate (i) immediately upon the death of
Consultant,  (ii) at the option of either party hereto without cause upon thirty
(30) days advance written notice from the terminating  party to the other party,
or (iii) upon the  termination  of this Agreement by the Contractor for "cause."
For the purposes of this Agreement, "cause" shall mean (i) any act by Consultant
of fraud or  dishonesty  (whether or not against or involving  the  Contractor),
(ii) Consultant's  competing with the business of the Contractor either directly
or  indirectly,  (iii)  Consultant's  breach of any  material  provision of this
Agreement,  (iv)  Consultant's  failure to devote his best efforts to his duties

                                       4
<PAGE>

under this Agreement or to perform such duties diligently and efficiently and in
accordance  with the  directions of the  Contractor or to otherwise  fulfill his
obligations  under this Agreement,  (v) Consultant's  failure to comply with the
decisions  or policies of the  Contractor,  (vi) any act of moral  turpitude  by
Consultant or (vii) any other matter constituting "cause" under applicable law.

            (b) This Agreement shall terminate  immediately  upon written notice
to  Consultant  if Consultant  shall at any time be  incapacitated  by reason of
physical or mental illness or otherwise incapable of performing the duties under
this Agreement for a continuous period of sixty (60) days.

            (c) The  Contractor's  obligation to pay  compensation to Consultant
under  Section  2  of  this  Agreement  shall  terminate  immediately  upon  the
termination of this Agreement for any reason.

      SECTION 14. INJUNCTIVE RELIEF.  Consultant acknowledges that breach of the
provisions of Sections 12 or 13 of this  Agreement  would result in  irreparable
injury  and  permanent   damage  to  the  Contractor,   which   prohibitions  or
restrictions Consultant acknowledges are both reasonable and necessary under the
circumstances,  singularly and in the aggregate, to protect the interests of the
Contractor.  Consultant  recognizes and agrees that the ascertainment of damages
in the event of a breach of the provisions of this Agreement would be difficult,
and that money damages alone would be an inadequate  remedy for the injuries and
damages which would be suffered by the Contractor  from breach of Sections 12 or
13 of this Agreement by Consultant.  Consultant  therefore agrees:  (i) that, in
the event of a breach of the provisions of Sections 12 or 13 of this  Agreement,
the  Contractor,  in  addition to and without  limiting  any of the  remedies or
rights  which it may have at law or in equity  or  pursuant  to this  Agreement,
shall have the right to injunctive  relief or other  similar  remedy in order to
specifically  enforce the  provisions  hereof;  and (ii) to waive and not to (A)
assert any defense to the effect that the Contractor  has an adequate  remedy at
law with respect to any such  breach,  (B) require  that the  Contractor  submit
proof of the  economic  value  of any  Trade  Secret,  or (C)  require  that the
Contractor post a bond or any other  security.  Nothing  contained  herein shall
preclude the Contractor  from seeking  monetary  damages of any kind,  including
reasonable fees and expenses of counsel and other expenses, in a court of law.

      SECTION 15.  NOTICES.  All notices  required and given  herewith  shall be
addressed to the  Contractor or Consultant  at the  designated  address as shown
below,  and shall be effective when personally  delivered by courier  (including
overnight  carriers)  or otherwise to the party to be given such notice or other
communication. The addresses for such notices shall be as follows:

except by written instrument of the party charged with such waiver or estoppel.

            (d) If any term or  provision  of this  Agreement  is held  illegal,

Agreement.

Secrets or Confidential  Information  owned by any other party.  Consultant also
agrees that during the course of  Consultant's  engagement,  Consultant will not
use or  disclose  any  confidential  information  or trade  secrets of any other
entity  or  third-party   unless   authorized  in  writing  by  that  entity  or
third-party.

            (c) The  obligations  under this  Agreement with regard to the Trade
Secrets  of  the  Contractor  remain  in  effect  as  long  as  the  information
constitutes a trade secret under  applicable law. The obligations with regard to
the  Confidential  Information  of the  Contractor  shall remain in effect while
Consultant  is engaged by the  Contractor  in any  capacity  and for a period of
three (3) years thereafter.

            (d)  Consultant  agrees  to  return  to  the  Contractor,  upon  the
termination of Consultant's  engagement (for any reason), or upon request by the
Contractor, the Trade Secrets and Confidential Information of the Contractor and
all materials relating thereto.

            (e)  As  used  herein,  "Trade  Secrets"  means  information  of the
Contractor, and its licensors,  suppliers, clients and customers, without regard
to  form,  including,  but not  limited  to,  technical  or  nontechnical  data,
formulas,  patterns,  compilations,   programs,  devices,  methods,  techniques,
drawings,  processes,  financial data, financial plans, product plans, or a list
of actual or potential customers or suppliers, which is not commonly known by or
available to the public and which information (i) derives economic value, actual
or  potential,  from  not  being  generally  known  to,  and not  being  readily
ascertainable  by proper means by, other persons who can obtain  economic  value
from  its  disclosure  or use and  (ii)  is the  subject  of  efforts  that  are
reasonable under the  circumstances to maintain its secrecy.  Trade Secrets also
include any information described in this paragraph which the Contractor obtains
from another party and which the Contractor  treats as proprietary or designates
as trade secrets,  whether or not owned or developed by the Contractor.  As used
herein, "Confidential Information" means information,  other than Trade Secrets,
that  possesses  an  element  of value to the  Contractor,  that is  treated  as
confidential,  and that would  potentially  damage the  Contractor if disclosed.

                                       3

Confidential  Information  includes,  but is not limited to, (i) future business
plans,  (ii) the  composition,  description,  schematic  or design of  products,
future products or equipment of the  Contractor,  (iii)  communication  systems,
system designs and related  documentation,  (iv) advertising or marketing plans,
(v)  information  regarding  employees,  independent  contractors,  clients  and
customers  of the  Contractor,  (vi)  information  concerning  the  Contractor's
financial structure and methods and procedures of operation, and (vii) the terms
and conditions of this  Agreement.  Confidential  Information  also includes any
information  described  in this  paragraph  which the  Contractor  obtains  from
another party and which the  Contractor  treats as  proprietary,  whether or not
owned or  developed  by the  Contractor.  Confidential  Information  need not be
marked or stamped "confidential" to qualify as such under this Agreement.

      SECTION 12. WORK PRODUCT.  All Work Product  (defined  below) shall be the
exclusive  property of the  Contractor.  If any of the Work  Product may not, by
operation of law or  otherwise,  be  considered  the  exclusive  property of the
Contractor,  or if  ownership  of all right,  title,  and  interest to the legal
rights  therein  shall  not  otherwise  vest   exclusively  in  the  Contractor,
Consultant  hereby  assigns  to the  Contractor,  and upon the  future  creation
thereof automatically assigns to the Contractor,  without further consideration,
the ownership of all Work Product. The Contractor shall have the right to obtain
and hold in its own  name  copyrights,  patents,  registrations,  and any  other
protection available in the Work Product.  Consultant will promptly disclose any
and all such Work Product to Contractor. Consultant agrees to perform, during or
after  termination of  Consultant's  engagement by the  Contractor,  and without
requiring  Contractor  to provide  any  further  consideration  therefore,  such
further acts as may be  necessary  or desirable to transfer,  perfect and defend
the Contractor's ownership of the Work Product as requested by the Contractor.

      For purposes of this Agreement, "Work Product" shall mean all discoveries,
designs, Trade Secrets,  Confidential Information,  trademarks, data, materials,
formulas,  research,  documentation,  computer programs,  communication systems,
audio  systems,   system  designs,   inventions  (whether  or  not  patentable),
copyrightable  subject  matter,  works  of  authorship,  and  other  proprietary
information  or work product  (including  all  worldwide  rights  therein  under
patent, copyright,  trademark,  trade secret,  confidential  information,  moral
rights and other property  rights),  which Consultant has made or conceived,  or
may make or conceive,  either  solely or jointly with  others,  while  providing
services to  Contractor  or with the use of the time,  material or facilities of
Contractor or relating to any of  Contractor's  actual or  anticipated  business
known  to  Consultant  while  engaged  by the  Contractor,  or  suggested  by or
resulting  from any task assigned to Consultant or work  performed by Consultant
for or on behalf of Contractor.

      SECTION 13. TERMINATION OF ENGAGEMENT.

            (a) This Agreement shall terminate (i) immediately upon the death of
Consultant,  (ii) at the option of either party hereto without cause upon thirty
(30) days advance written notice from the terminating  party to the other party,
or (iii) upon the  termination  of this Agreement by the Contractor for "cause."
For the purposes of this Agreement, "cause" shall mean (i) any act by Consultant
of fraud or  dishonesty  (whether or not against or involving  the  Contractor),
(ii) Consultant's  competing with the business of the Contractor either directly
or  indirectly,  (iii)  Consultant's  breach of any  material  provision of this
Agreement,  (iv)  Consultant's  failure to devote his best efforts to his duties

                                       4

under this Agreement or to perform such duties diligently and efficiently and in
accordance  with the  directions of the  Contractor or to otherwise  fulfill his
obligations  under this Agreement,  (v) Consultant's  failure to comply with the
decisions  or policies of the  Contractor,  (vi) any act of moral  turpitude  by
Consultant or (vii) any other matter constituting "cause" under applicable law.

            (b) This Agreement shall terminate  immediately  upon written notice
to  Consultant  if Consultant  shall at any time be  incapacitated  by reason of
physical or mental illness or otherwise incapable of performing the duties under
this Agreement for a continuous period of sixty (60) days.

            (c) The  Contractor's  obligation to pay  compensation to Consultant
under  Section  2  of  this  Agreement  shall  terminate  immediately  upon  the
termination of this Agreement for any reason.

      SECTION 14. INJUNCTIVE RELIEF.  Consultant acknowledges that breach of the
provisions of Sections 12 or 13 of this  Agreement  would result in  irreparable
injury  and  permanent   damage  to  the  Contractor,   which   prohibitions  or
restrictions Consultant acknowledges are both reasonable and necessary under the
circumstances,  singularly and in the aggregate, to protect the interests of the
Contractor.  Consultant  recognizes and agrees that the ascertainment of damages
in the event of a breach of the provisions of this Agreement would be difficult,
and that money damages alone would be an inadequate  remedy for the injuries and
damages which would be suffered by the Contractor  from breach of Sections 12 or
13 of this Agreement by Consultant.  Consultant  therefore agrees:  (i) that, in
the event of a breach of the provisions of Sections 12 or 13 of this  Agreement,
the  Contractor,  in  addition to and without  limiting  any of the  remedies or
rights  which it may have at law or in equity  or  pursuant  to this  Agreement,
shall have the right to injunctive  relief or other  similar  remedy in order to
specifically  enforce the  provisions  hereof;  and (ii) to waive and not to (A)
assert any defense to the effect that the Contractor  has an adequate  remedy at
law with respect to any such  breach,  (B) require  that the  Contractor  submit
proof of the  economic  value  of any  Trade  Secret,  or (C)  require  that the
Contractor post a bond or any other  security.  Nothing  contained  herein shall
preclude the Contractor  from seeking  monetary  damages of any kind,  including
reasonable fees and expenses of counsel and other expenses, in a court of law.

      SECTION 15.  NOTICES.  All notices  required and given  herewith  shall be
addressed to the  Contractor or Consultant  at the  designated  address as shown
below,  and shall be effective when personally  delivered by courier  (including
overnight  carriers)  or otherwise to the party to be given such notice or other
communication. The addresses for such notices shall be as follows:

condition of this Agreement shall be deemed to have been waived, nor shall there
be any estoppel  against the  enforcement  of any  provision of this  Agreement,
except by written instrument of the party charged with such waiver or estoppel.

            (d) If any term or  provision  of this  Agreement  is held  illegal,
invalid or unenforceable,  such illegality,  invalidity or unenforceability will
not affect the  legality,  validity or  enforceability  of the remainder of this
Agreement.
