between the Executive and the Company.

     NOW,  THEREFORE,  in consideration of the mutual covenants,  agreements and
representations contained herein, the parties hereto agree as follows:

     1. TERM.  The Company will employ the  Executive,  and the  Executive  will
serve  the  Company,  under the  terms of this  Agreement  for a term of two (2)
years,  commencing on the date hereof,  which term shall be subject to automatic
renewal for  successive  one-year  terms unless either party  notifies the other
party of its or his intent not to renew this Agreement (which non-renewal may be

of the  applicable  term or renewal term.  Notwithstanding  the  foregoing,  the
Executives  employment  hereunder  may be earlier  terminated,  as  provided  in
Section 4 hereof. The term of this Agreement,  as in effect from time to time in
accordance  with the  foregoing,  shall be referred  to herein as the Term.  The
period of time between the  commencement  and the  termination of the Executives
employment hereunder shall be referred to herein as the Employment Period.

     2. EMPLOYMENT.

          d. Other Benefits.  During the Employment  Period, the Executive shall

     4.   TERMINATION OF EMPLOYMENT.

          a.  Termination  for Cause.  The Company may at any time terminate the
Executives  employment  hereunder for cause.  For purposes of this Agreement and
subject to the Executives  opportunity to cure to the extent provided in Section
4.c. hereof, the Company shall have cause to terminate the Executives employment

               (1)  Fraud  in  connection  with  the   Executive's   performance
          hereunder;

               (2)  Dishonesty in connection  with the  Executive's  performance
          hereunder  except to the extent the Executive  proves such  dishonesty
          was both unintentional and covered only a matter which was de minimis;

               (3) The failure by the Executive to perform his duties  hereunder
          or any other breach by Executive of this Agreement;

               (4) The failure by the Executive to follow the lawful  directions
          of or  policies  established  by the Board of  Directors  or the Chief
          Executive  Officer  of the  Company  unless  the tasks are of the type
          which could not  reasonably be required of Executive  pursuant to this
          Agreement;

               (5) The conviction  for, or plea of nolo  contendere to, a charge
          of commission of a felony or crime involving moral turpitude;

               (6)  The  Executive's  performance  of any  services  under  this
          Agreement  while  under  the  influence  of  drugs,   alcohol  or  any
          controlled  substance  except,  with respect to controlled  substances
          only,  to the  extent  Executive  proves  (a)  taking  any  controlled
          substance  was  prescribed  by a  medical  doctor  to treat a  medical
          problem,  (b) such  controlled  substance  was used only in accordance
          with  said  doctor's  instructions,  and (c)  taking  such  controlled
          substance  does  not and  did not  adversely  affect  Executive's  job
          performance during more than a de minimis period of time; or

               (7) The  Executive  acting  in a manner  which  damages  or could
          reasonably  be expected to damage the  business or  reputation  of the
          Company.

          The parties agree that each of the foregoing breaches, events, crimes,
behaviors,  acts, inactions or occurrences  constitutes  independent grounds for
"cause" and the failure of any breach, event, crime, behavior,  act, inaction or
occurrence to constitute  "cause" under any paragraph of this Section 4.a. shall
not  prevent  that  same  breach,  event,  crime,  behavior,  act,  inaction  or
occurrence from constituting "cause" under a different paragraph of this Section
4.a.

                                       3

          b. Termination for Good Reason.  The Executive shall have the right at
any time to terminate  his  employment  with the Company and for any reason upon
twenty  (20) days prior  written  notice.  For  purposes of this  Agreement  and
subject to the Companys  opportunity to cure as provided in Section 4.c. hereof,
the Executive shall have good reason to terminate his employment  hereunder only
if such termination shall be the result of:

          (1)  A  breach  by  the  Company  of  the  compensation  and  benefits
     provisions set forth in Section 3 hereof; or

          (2) A material  breach by the  Company of any other  material  term of
     this Agreement.

stating with reasonable  specificity the reason for the termination (breach) and
(2) if such breach is susceptible  of cure or remedy,  a period of ten (10) days
from and  after  the  giving of such  notice  shall  have  elapsed  without  the
breaching  party having  effectively  cured or remedied  such breach during such
10-day  period,  unless such breach cannot be cured or remedied  within ten (10)
days,  in which  case the period  for  remedy or cure  shall be  extended  for a
reasonable  time  (not to exceed  an  additional  ten (10)  days)  provided  the
breaching  party has made and continues to make a diligent effort to effect such
remedy  or cure.  Notwithstanding  anything  contained  in this  Agreement,  the
parties  agree that any breach,  event,  crime,  behavior,  action,  inaction or
occurrence  constituting cause (or which would constitute cause after the giving
of notice)  under  Section  4.a.(1),  (2),  (5),  (6) or (7) shall not under any
circumstances  be  susceptible  or capable of cure or remedy  under this Section
4.c.

          d.  Termination  Upon Death or  Permanent  and Total  Disability.  The
Employment  Period shall  automatically  without further action be terminated by
the death of the  Executive.  The  Employment  Period may be  terminated  by the
Company at any time if the Executive  shall be rendered  incapable of performing
his  duties  to the  Company  at the  same  level  by  reason  of any  medically
determined  physical or mental impairment that (i) can reasonably be expected to
result in death or (ii) can  reasonably  be expected to last or has lasted for a
period  of three (3) or more  consecutive  months or for a period of four (4) or

Executives  impairment  or absence or  projected  absence due to the  disability
(Disability).  If the Employment  Period is terminated by reason of a Disability
of the Executive, the Company shall give thirty (30) days advance written notice
to that effect to the Executive.

     5.   CONSEQUENCES OF TERMINATION.

     Agreement  on  each  such  date if  Executive's  employment  had  not  been
     terminated. Executive shall also receive, at the time bonuses are otherwise

     comparable substitute coverage from another employer at any time during the
     Severance Period. The Executive shall be entitled, at the expiration of the
     Severance  Period,  to elect continued  medical coverage in accordance with
     Section  4980B of the  Internal  Revenue  Code of 1986,  as amended (or any

employment hereunder for any reason other than (a) without cause or (b) for good
reason  (i.e.,  termination  for death,  Disability,  with cause or without good
reason), or if Executive makes the election provided for in Section 8, or if the
Term is not renewed,  the  Executive  shall be paid base salary only through the
date of termination or  non-renewal,  and Executive shall not be entitled to any
severance,  bonus or other pay, or any benefits  continuation rights, except for

rights therein (including patents thereon), in any and all countries;  provided,
however, that said contributions and inventions will be the property of Company,

protection, as the case may be.

     8.  NON-COMPETITION.  The  Executive  agrees  that he shall not  during the

reasonably be expected to cause customers not to use the Company's or any of its
subsidiaries' or affiliates' products or services or (b) which are similar to or
competitive with products or services provided or supplied by the Company or any
of its subsidiaries or affiliates.  Notwithstanding the foregoing, the Executive
shall not be prohibited during the non-competition  period applicable above from
acting as a passive  investor  by owning not more than one  percent  (1%) of the
issued  and  outstanding  capital  stock  of  any  publicly-held   company.  The
Executive,  at his option, may elect to eliminate the above restrictions in this
Section 8 only during the Severance Period but any such election shall,  without
further  action,  be deemed  an  automatic  and  irrevocable  relinquishment  by
Executive and termination of all of his rights to pay and benefits under Section
5.a. During the Employment Period and the Severance  Period, if applicable,  and
for a period of one (1) year  after the later of  expiration  of the  Employment
Period and the  Severance  Period,  the Executive  shall not,  without the prior
written  consent  of the  Board  of  Directors  of  the  Company,  directly,  or
indirectly,  alone or as partner, joint venturer,  officer, director,  employee,
consultant, agent, independent contractor, stockholder or otherwise, (a) solicit
or induce any employee,  independent  contractor or consultant of the Company or
any current or future subsidiary or affiliate thereof to terminate or reduce his
or her  employment  or  engagement  with the  Company  or any  current or future
subsidiary  or affiliate  thereof or (b) solicit the business of or any business
from any current or future customer or supplier to the Company or any current or
future  subsidiary or affiliate  thereof or induce any such customer or supplier
not to do business with or reduce its business  transactions with the Company or
any subsidiary or affiliate thereof.

     9. BREACH OF RESTRICTIVE COVENANTS; SEVERABILITY. The parties hereto intend
all provisions of this Agreement to be enforced to the fullest extent  permitted
by law. The parties agree that Sections 6, 7 and 8 are  reasonable and necessary
to protect the Companys  interests and properties and that a breach or violation
of Sections 6, 7 or 8 hereof will result in immediate and irreparable injury and
harm to the innocent party,  who shall have, in addition to any and all remedies
of law and other consequences under this Agreement,  the right to an injunction,
specific  performance or other equitable  relief to prevent the violation of the
covenant or agreement  hereunder.  The parties agree that each of such covenants
and  agreements  is separate,  distinct and severable not only from the other of
such covenants and  agreements but also from the other and remaining  provisions
of this Agreement;  that the  unenforceability of any such covenant or agreement
shall not affect the validity or  enforceability  of any other such covenants or
agreements  or any other  provision or provisions  of this  Agreement.  Should a

                                       6
<PAGE>

court of competent  jurisdiction  determine  that the scope of any  provision of
this  Agreement is too broad to be enforced as written,  the parties intend that
the court should reform the provision to such narrower scope as it determines to
be  enforceable.  If,  however,  any  provision of this  Agreement is held to be
illegal or  unenforceable or by its severance,  invalid or  unenforceable  under
present  or  future  law,  such  provision  shall be fully  severable  from this
Agreement,  this  Agreement  shall be construed and enforced as if such illegal,
invalid or  unenforceable  provision  were never a part hereof and the remaining
provisions of this Agreement shall remain in full force and effect and shall not
be  affected  by the  illegal,  invalid  or  unenforceable  provision  or by its
severance.

     10. NOTICE.  For the purposes of this Agreement,  notices,  demands and all
other  communications  provided  for in this  Agreement  shall be in writing and

conduct of any action or proceeding in any such court based on improper venue or
forum non conveniens,  waives  personal  service of any and all process upon it,
and consents that all service of process may be made by mail or courier  service
directed to it at the address  designated for it set forth in this Agreement and
that service so made shall be deemed to be completed  upon the earlier of actual
receipt  or ten (10) days after the same  shall  have been  posted.  Each of the
parties hereby waives,  to the fullest extent  permitted by applicable  law, any
right it may have to a trial by jury in respect of any  litigation  directly  or
indirectly  arising out of, under or in connection with this Agreement.  Each of
the parties certifies that no representative,  agent or attorney of either party
has represented,  expressly or otherwise, that the other would not, in the event
of litigation, seek to enforce the foregoing waivers.

b. The prevailing party in any proceeding  brought under this Agreement shall be
reimbursed  by the  other  party for all  costs,  fees and  expenses,  including
without  limitation,  attorneys fees and expenses,  incurred by such  prevailing
party in preparation for, in the investigation of, and/or otherwise  directly or
indirectly in connection with any such proceeding.

law or regulation or as agreed to by Executive and Company.

     15.   COUNTERPARTS.   This  Agreement  may  be  executed  in  one  or  more
counterparts,  each of which shall be deemed to be an original  but all of which

     16.  GOVERNING  LAW.  Except as set forth in Section 3.f.,  this  Agreement
shall be construed,  interpreted and enforced in accordance with the laws of the
State of New York,  without  giving  effect to the  conflict  of law  principles
thereof.  The parties have selected a New York choice of law for this  Agreement
because the Company is relocating its offices to New York.

     17. ENTIRE  AGREEMENT.  This Agreement  constitutes the entire agreement by
the Company and the Executive  with respect to the subject matter hereof (except
with respect to the stock options referred to in Section 3.c. which shall not be
governed by this  Agreement)  and  supersedes  any and all prior  agreements  or

with the drafting and  negotiation  of this Agreement . Each party hereby waives

that any provision thereof is unenforceable,  illegal, invalid or unconscionable
arising out of or relating to his failure to retain  counsel in connection  with
this transaction.
