accordance with the terms of this Amendment; and

         WHEREAS, Section 10.08 of the Agreement provides that the Agreement may
be amended by a written instrument signed by the parties to the Agreement.

         NOW, THEREFORE,  in consideration of the  representations,  warranties,
covenants  and  agreements  hereinafter  contained,  and intending to be legally
bound hereby, the parties hereby agree as follows:

         1.1 Section  3.05(a) of the  Agreement;  Definition of "Outside  Date".
             ------------------------------------------------------------------
Section  3.05(a) of the Agreement  shall be deleted and replaced in its entirety

         Agreement  on or after the  Outside  Date if the  principal  reason the
         transactions  contemplated  hereby shall not have been  consummated  by
         such time is the willful and  material  breach by such party (or in the
         case of Purchaser,  by Cyber Digital or Acquisition  Sub) of any of its
         or their obligations under this Agreement;"

         1.2 Governing Law. All of the terms,  conditions,  and other provisions

             ------------------------
hereof shall be binding upon and inure to the benefit of the parties  hereto and
their respective  successors and permitted  assigns.  Neither this Amendment nor
any of the rights,  interests or obligations  hereunder shall be assigned by any
of the parties  hereto  without the prior  written  consent of the

not a party to this  Amendment  which acquires all or  substantially  all of the
assets  of  Acquisition  Sub  or  Cyber  Digital  and  who  assumes  all  of the
obligations of Acquisition Sub or Cyber Digital  hereunder,  as the case may be,
provided in each such case that no such assignment shall release Acquisition Sub
or Cyber Digital, as the case may be, from its duties and obligations hereunder,
and (ii) Seller may assign all or part of this Amendment or its rights hereunder
to an  Affiliate  of  Seller  who  assumes  all of  the  obligations  of  Seller

and obligations hereunder.

         1.4 Counterparts.  This Amendment may be executed simultaneously in two
             ------------
or more  counterparts,  each of which  shall be deemed an  original,  but all of
which together shall constitute one and the same instrument.
