                                     RECITAL


         A.  The parties to the Agreement deem it advisable to amend the
Agreement to provide that all of the 480,000 shares of Common Stock of Parent to
be issued pursuant to the Agreement will be placed into the Escrow Fund in order
to provide for an additional means for satisfaction of any claims by Parent for
Losses during the term of the Escrow Fund without resort to personal legal
action against the Company's shareholders during such term.

         B.  In addition the parties to the Agreement deem it advisable to 
amend the Agreement to correct representation 3.3(a) of the Agreement by adding
the reference to the non-statutory options granted to the certain directors of
Parent.

         The parties intending to be legally bound, agree as follows:

                                    AGREEMENT


         1.       Recital C of the Agreement is hereby amended in its entirety 
                  to read as follows:

                  "C.      All of the stock otherwise payable by Parent in 
                  connection with the Merger shall be placed in escrow by Parent
                  for the purposes of satisfying damages, losses, expenses and
                  other similar charges which result from breaches of
                  representations, warranties or covenants, all as set forth in
                  Article VII hereof."

         2.       Section 1.7(b) of the Agreement is hereby amended in its 
                  entirety to read as follows:

                  "(b)     Parent to Provide Cash and Deposit Stock.  At 
                           ----------------------------------------
                  Closing, Parent shall make available to the Exchange Agent 
                  for exchange in accordance with this Article I, the

 
                  cash deliverable pursuant to Section 1.6(a) in exchange for
                  outstanding shares of Company Capital Stock; and, on behalf of
                  the holders of Company Capital Stock, Parent shall deposit
                  into the Escrow Fund (as defined below in Section 7.2(a)) an
                  aggregate of 480,000 shares of Parent Common Stock (the
                  "Escrow Amount") out of the Merger Consideration otherwise
                  payable pursuant to Section 1.6(a). The portion of the Escrow
                  Amount deposited into escrow on behalf of each holder of
                  Company Capital Stock shall be deemed issued and outstanding
                  Parent Common Stock in the name of such holder and shall be in
                  proportion to the aggregate number of shares of Parent Common
                  Stock which such holder would otherwise be entitled to receive
                  under Section 1.6(a) by virtue of such holder's ownership of
                  outstanding shares of Company Capital Stock. The Surviving
                  Corporation will pay the Option Purchase Amount for payment
                  pursuant to Section 1.6(e) as soon as practical after the
                  Closing."

         3.       Section 1.7(c) of the Agreement is hereby amended in its 
                  entirety to read as follows:

                  "(c) Exchange Procedures. On the Closing Date, (i) each holder
                       -------------------
                  of record of a certificate or certificates (collectively, the

                  Effective Time represented outstanding shares of Company
                  Capital Stock whose shares were converted into the right to
                  receive shares of Parent Common Stock and cash pursuant to
                  Section 1.6(a), will deliver to the Exchange Agent the Company
                  Stock Certificate(s) for cancellation, together with a letter
                  of transmittal and an executed stock power in blank, and (ii)
                  the Exchange Agent will deliver to each such holder of record
                  of the Company Stock Certificate(s) the cash portion of the
                  Merger Consideration Per Share in accordance with Section
                  1.6(a)(ii), and the Company Stock Certificates so surrendered
                  shall forthwith be canceled. Until so surrendered, each
                  outstanding Company Stock Certificate that, prior to the
                  Effective Time, represented shares of Company Capital Stock
                  will be deemed from and after the Effective Time, for all
                  corporate purposes, to evidence the ownership of the number of
                  full shares of Parent Common Stock (rounded to the nearest
                  whole share) into which such shares of Company Capital Stock
                  shall have been so converted (which shares of Parent Common
                  will be deposited by the Exchange Agent into the Escrow Fund)
                  and the right to receive an amount in cash as provided in
                  Section 1.6(a)(ii) hereof. As soon as practicable after the
                  Effective Time, and subject to and in accordance with the
                  provisions of Article VII hereof, Parent shall cause to be
                  deposited with the Escrow Agent (as defined in Article VII)
                  the sum of the Escrow Amount, which amount shall be available
                  to compensate Parent as provided in Article VII."


         4.       Section 3.3(a) of the Agreement is hereby amended in its 
                  entirety to read as follows:

                  "(a) The authorized stock of Parent consists of 20,000,000
                  shares of Common Stock, $.001 par value, of which 6,805,837
                  shares were issued and outstanding as of 

                                      -2-

                  authorized, and all such issued and outstanding shares have
                  been validly issued, are fully paid and nonassessable and are
                  free of any liens or encumbrances other than any liens or
                  encumbrances created by or imposed upon the holders thereof.
                  Parent has also reserved (i) 1,550,000 shares of Common Stock

                  for issuance pursuant to individual non-statutory options

                  options, warrants, calls, rights, commitments or agreements of
                  any character to which Parent is a party or by which it is
                  bound obligating Parent to issue, deliver, sell, repurchase or
