                    disposition  or assignment for the benefit of its respective
                    creditors;

               v)   The Consultant attempts to assign this Agreement without the

          (b) In  addition to the  Consulting  Fee,  for each of the  Consulting
     Period and the  Extension  Period,  the Company  shall pay to  Consultant a
     commission  (the  "Commission  Payment") equal to (i) three (3%) percent of
     the first  $1,000,000 of the net sale price of all Products sold during the

     arrears, in accordance with Section 4(e).

          (c) "The net sale price of all  Products  sold  during the  applicable
     period," as used herein, means the price at which  Communication/Networking
     Products,  as hereinafter  defined,  are sold by the Company, not including
     taxes,  freight  or  transportation  or other such  charges or costs,  less
     returns,  the  costs  of  collections,  and  standard  trade  discounts  or

     allowances and special  reductions and changes in any of the foregoing from
     time   to   time   shall   be   in   the   discretion   of   the   Company.
     "Communication/Networking  Products"  shall be those  Products set forth on
     Schedule  A hereof  or  otherwise  designated  as  Communication/Networking
     Products on the internal records of the Company, in its sole discretion.

          (d) The Company shall, as soon as practicable  after the close of each
     Communication/Networking  Products  calendar quarter prepare and deliver to
     Consultant  a statement  of the  amounts of  revenues  from the sale of all
     Communication/Networking  Products and of Consultant's  commissions for the
     reported  period.  Within 10 days after the delivery of any such statement,
     Consultant


                                       -3-

statement.  In the event that  Consultant  does not object to the  statement  in
accordance  with this Section 4(d),  such  statement  shall deemed  accepted and
shall become final and binding upon the parties.  If Consultant  shall object to
the  statement,  and the parties  cannot  agree as to the subject  matter of the
statement,  the matter shall be submitted to the Company's independent auditors,
whose  determination,  to be  rendered  in not more than 30 days of  submission,
shall be final and binding  upon the  parties.  Payment of any  commissions  due
shall be made not  later  than 10 days  after  acceptance  of the  statement  or
resolution or determination of any objection, as the case may be.

          (e) If Consultant's engagement is terminated pursuant to Sections 3(a)
     or (b),  or if  Consultant  terminates  its  engagement  voluntarily,  then
     Consultant  shall not be entitled to any  compensation  from and after such
     date of termination.

          (f) As  further  compensation  for  the  Services  to be  rendered  by

     Consultant  a three (3) year  option to  purchase  50,000  shares of Common
     Stock  at an  exercise  price of  $1.25  per  share.  The  option  shall be
     exercisable  (i) as to 25,000  shares,  commencing 30 days after the end of
     the Consulting  Period, in full, if the net sale price of all Products sold
     during the  Consulting  Period equals at least  $3,000,000,  and (ii) as to
     25,000 shares, commencing 30 days after the end of the Extension Period, in
     full,  if the net sale price of all  Products  sold  during  the  Extension
     Period equals at least  $3,000,000.  The option  agreement  shall  provide,
     among other  things,  that (i) if the net sale price of all  Products  sold
     shall be less than  $3,000,000  during either the Consulting  Period or the
     Extension Period, then the number of shares as to which the option shall be
     exercisable  as relates to such period shall be decreased in  proportion to
     the amount by which such net sale price is less than  $3,000,000,  and (ii)
     if Consultant's engagement is terminated (A) pursuant to Section 3(a) or if
     Consultant terminates its engagement voluntarily, then the number of shares
     as to which the option shall be  exercisable  shall be determined as of the
     date of such termination,  or (B) pursuant to Section 3(b), then the option
     shall  terminate  as to any and all  shares,  and  Consultant  shall not be
     entitled to exercise the option as to any shares.

     5.   Expenses.

     The  Consultant  shall be  solely  responsible  for  paying  any  expenses,
including,   without  limitation,   salaries  and  commissions  of  Consultant's

supplies,  licenses,  and  telephone  incurred by Consultant or its employees in
