         13.  Restrictive Covenant:

          [A] Employee  acknowledges that: (i) the business in which the Company
is engaged is intensely  competitive and that his employment by the Company will
require that he have access to and knowledge of confidential  information of the
Company,  including,  but not limited to, certain of the Company's  confidential
plans for the creation, acquisition or disposition of products, expansion plans,

business,  and are "trade  secrets" of the Company;  (ii) the direct or indirect
disclosure  of any  such  confidential  information  to  existing  or  potential
competitors of the Company would place the Company at a competitive disadvantage
and would cause damage,  financial and otherwise, to the Company's business; and
(iii) by his training,  experience  and  expertise,  some of his services to the
Company will be special and unique.

         Employee  understands  and agrees that such trade  secrets  give or may
give  the  Company  a  significant   competitive  advantage.   Employee  further
recognizes that the success of the Company depends on keeping  confidential both
the  trade  secrets  already   developed  or  to  be  acquired  and  any  future
developments of trade secrets.  Employee  understands  that in his capacity with
the Company he will be entrusted  with  knowledge of such trade  secrets and, in
recognition of the importance  thereof and in consideration of his employment by
the  Company  hereunder,  agrees  that he will not,  without  the consent of the
President/CEO in writing,  make any disclosure of trade secrets now or hereafter
possessed  by the  Company to any  person,  partnership,  corporation  or entity
either  during or after the term  hereunder,  except  to such  employees  of the
Company or its  subsidiaries  or affiliates,  if any, as may be necessary in the
regular  course of business and except as may be required  pursuant to any court
order,  judgment  or  decision  from any court of  competent  jurisdiction.  The
provisions  of this  Section  13[A]  shall  continue  in full  force and  effect
notwithstanding any termination of this Agreement.

         [B]  Employee  agrees that during the term of his  employment  with the
Company  and for a  period  of two  years  thereafter  he will not  directly  or

competitive  with any business then being planned or conducted by the Company or
its divisions and subsidiaries.  For the purpose hereof,  "substantial  security
holder" shall mean  ownership,  directly or  indirectly,  of more than 3% of any
class of securities of a company or partnership  interest in any  partnership or
indebtedness  of any such entity in excess of $25,000.  The  provisions  of this
Section  13[B]  shall  continue  in full  force and effect  notwithstanding  any

trade  secrets  hereafter  made,  prepared,  invented,   discovered,   acquired,
suggested  or reduced to practice  (hereinafter  designated  and  referred to as

made,  discovered  or conceived  of by him , alone or with  others,  at any time
during his employment with the Company, whether on the Company's or his own time
and irrespective of whether on or off the Company's premises, provided only that
such Property Rights (1) relate to or are useful in any phase of the business in
which the Company may be engaged during the period of employment,  or (2) relate
to any subject matter or problems within the scope of Employee's employment,  or
(3)  relate  to or  involve  the use of any data or  information  of  which  the
Employee  has been or may  become  informed  by  reason of  employment  with the
Company. The Employee hereby appoints the Company as Employee's attorney-in-fact

secrets,   trademarks,   service  marks,   secret   processes,   discoveries  or
improvements, during his employment by the Company. Employee's cooperation after
his  employment  is  subject  to his  availability  and the  Company  agrees  to
reimburse  Employee  for loss of income  and  expenses  incurred  in  connection
therewith. Said cooperation shall not be withheld by Employee.

the  Company,  through the  expenditure  of  considerable  time and money,  will
acquire, has developed and will continue to develop in the future,  information,
skills, confidential information,  know-how,  formulae,  technical expertise and
methods  relating to or forming part of the Company's  services and products and
conduct of its business, and that the same are confidential and proprietary, and
are "trade  secrets" of the Company.  Employee  understands and agrees that such
trade secrets give or may give the Company a significant  competitive advantage.
Employee  further  recognizes that the success of the Company depends on keeping
confidential  both the trade secrets already developed or to be acquired and any
future developments of trade secrets.  Employee understands that in his capacity
with the Company he will be entrusted  with knowledge of such trade secrets and,
in recognition of the importance  thereof and in consideration of his employment
by the Company  hereunder,  agrees that he will not,  without the consent of the
President/CEO in writing,  make any disclosure of trade secrets now or hereafter
possessed  by the  Company to any  person,  partnership,  corporation  or entity
either  during or after the term  hereunder,  except  to such  employees  of the
Company or its  subsidiaries  or affiliates,  if any, as may be necessary in the
regular  course of business and except as may be required  pursuant to any court
order,  judgment  or  decision  from any court of  competent  jurisdiction.  The
provisions   of  this   Section   shall   continue  in  full  force  and  effect
notwithstanding any termination of the Agreement.

termination of employment,  and shall  thereafter be exercisable for the maximum
period of time allowed for exercise  thereof  under the terms of the  applicable
Company stock option plan(s), provided that such period shall not exceed 90 days
following  such  termination.  An election  by the  Employee  to  terminate  his
employment under the provisions of Section 18[D] shall not be deemed a voluntary

policies.
