          limited number of persons who have  developed,  or will be responsible
          for developing the Company's Business, (iii) the Company's Business is

               (b) During and after the period  during  which the  Executive  is
          employed,  the  Executive  shall keep  secret and retain in  strictest
          confidence,  and  shall  not use for his  benefit  or the  benefit  of

          Company's Business,  learned by the Executive  heretofore or hereafter
          directly or  indirectly  from the Company (the  "Confidential  Company
          Information"), including, without limitation, information with respect
          to (i) the strategic plans, budgets, forecasts,  intended expansion of

          confidential and without breach of this Agreement. Notwithstanding the
          foregoing,  this Section 6.1(b) shall not apply to the extent that the
          Executive  is acting to the  extent  necessary  to comply  with  legal
          process;  provided  that in the event that the Executive is subpoenaed
          to testify or to  produce  any  information  or  documents  before any
          court,  administrative agency or other tribunal relating to any aspect
          pertaining  to the Company,  he shall  immediately  notify the Company
          thereof.

               (c) During the period  commencing  on the date  hereof and ending
          two (2) years  following  the later to occur of dates  upon  which the
          Executive shall cease to be an (i) employee or (ii) an "affiliate", as
          defined in Rule 144 promulgated  under the Securities Act of 1993, and
          the rules and  regulations  promulgated  thereunder  (as amended,  the
          "1993 Act"),  of the Company,  the  Executive  shall not,  without the
          Company's prior written  consent,  directly or indirectly,  solicit or
          encourage to leave the  employment or other service of the Company any
          employee or independent  contractor  thereof or hire (on behalf of the
          Executive  or any other  person,  firm,  corporation  or  entity)  any
          employee or  independent  contractor  who has left the  employment  or
          other service of the Company within one (1)

                                      -13-


          year of the termination of such employee's or independent contractor's
          employment  or other  service with the Company.  During such a one (1)
          year period,  the Executive  will not,  whether for his own account or
          for the  account  of any  other  person,  firm,  corporation  or other
          entity,  intentionally interfere with the Company's relationship with,
          or  endeavor to entice away from the Company any person who during the
          Term is or was a customer or client of the Company.

               (d) All memoranda,  notes, lists, records, property and any other
          tangible product and documents (and all copies thereof) made, produced
          or  compiled  by the  Executive  or made  available  to the  Executive
          concerning  the Business of the Company,  including  all  Confidential
          Company  Information,  shall be the  Company's  property  and shall be
          delivered to the Company at any time on request.

          6.2 Rights and Remedies upon Breach . (a) The  Executive  acknowledges
     and agrees that any breach by him of any of the  provisions  of Section 6.1
     hereof (the "Restrictive Covenants") would result in irreparable injury and
     damage  for which  money  damages  would not  provide an  adequate  remedy.
     Therefore, if the Executive breaches or threatens to commit a breach of any
     of the  provisions  of  Section  6. 1 hereof,  the  Company  shall have the
     following  rights and remedies,  each of which rights and remedies shall be
     independent of the other and severally enforceable, and all of which rights
     and remedies  shall be in addition to, and not in lieu of, any other rights
     and remedies  available to the Company  under law or in equity  (including,
     without limitation,  the recovery of damages):

               (i) The  right  and  remedy  to have  the  Restrictive  Covenants
          specifically  enforced  (without  posting bond and without the need to
          prove  damages) by any court having  equity  jurisdiction,  including,
          without  limitation,  the right to an entry  against the  Executive of
          restraining orders and injunctions (preliminary,  mandatory, temporary
          and permanent) against  violations,  threatened or actual, and whether
          or not then continuing, of such covenants.

               (ii) The right and remedy to require the Executive to account for
          and  pay  over  to the  Company  all  compensation,  profits,  monies,
          accruals,  increments  or other  benefits  (collectively,  "Benefits")
          derived  or  received  by  him  as  the  result  of  any  transactions
          constituting a


                                      -14-


          breach of the Restrictive  Covenants,  and the Executive shall account
          for and pay over such Benefits to the Company and, if applicable,  its
          affected subsidiaries and/or affiliates.

          (b)  The  Executive   agrees  that  in  any  action  seeking  specific
     performance or other equitable  relief,  he will not assert or contend that
     any of the  provisions  of this  Section 6 are  unreasonable  or  otherwise
     unenforceable.  The  existence  of any  claim  or cause  of  action  by the
     Executive,  whether  predicated on this  Agreement or otherwise,  shall not
     constitute a defense to the  enforcement of the Restrictive  Covenants.

     7. Other Provisions.

          7.1  Severabilitv.  The Executive  acknowledges and agrees that (i) he
     has had an  opportunity  to seek advice of counsel in connection  with this
     Agreement and (ii) the Restrictive Covenants are reasonable in geographical
     and temporal scope and in all other respects.  If it is determined that any
     of the provisions of this Agreement,  including, without limitation, any of
     the   Restrictive   Covenants,   or  any  part   thereof,   is  invalid  or
     unenforceable,  the remainder of the provisions of this Agreement shall not
     thereby be affected and shall be given full effect,  without  regard to the
     invalid portions thereof.

          7.2  Duration  and  Scope  of   Covenants.   If  any  court  or  other
     decision-maker of competent jurisdiction determines that any of Executive's
     covenants contained in this Agreement,  including,  without limitation, any
     of the Restrictive Covenants, or any part thereof, is unenforceable because
     of the duration or geographical  scope of such provision,  then, after such
     determination has become final and  unappealable,  the duration or scope of
     such provision, as the case may be, shall be reduced so that such provision
     becomes  enforceable and, in its reduced form, such provision shall then be
     enforceable and shall be enforced.

          7.3  Enforceability;  Jurisdictions.  Any controversy or claim arising
     out of or relating to this  Agreement or the breach of this  Agreement that
     is not  resolved  by  Executive  and the Company  (or its  subsidiaries  or
     affiliates,  where  applicable),  other than those  arising under Section 6
     thereof,  to the extent  necessary for the Company (or its  subsidiaries or
     affiliates,  where  applicable)  to avail itself of the rights and remedies
     provided under Section 6.2 hereof, shall be submitted to arbitration

     in New York, New York in accordance with New York law and the procedures of
     the   American   Arbitration   Association.   The   determination   of  the
     arbitrator(s)  shall be  conclusive  and  binding  on the  Company  (or its
     subsidiaries  or affiliates,  where  applicable) and Executive and judgment
     may  be  entered  on  the   arbitrator(s)'   award  in  any  court   having
     jurisdiction.
