                   ------

     B.   The Company and Digate are parties to that certain Pledge Agreement,
dated as of June 19, 2000 (the "Pledge Agreement"), whereby Digate agreed to
                                ----------------
pledge the Shares to the Company as security for the repayment of the principal
and interest outstanding under the Note.

     C.   As of the date hereof, 167,800 Shares remain pledged pursuant to the
Pledge Agreement, and $307,959.05 in principal and interest are outstanding

     D.   The Company desires to accept as full payment of all of Digate's
outstanding obligations under the Note, and Digate desires to secure all rights,
title and interest in and to, the remaining Shares pledged pursuant to the
Pledge Agreement, upon the terms and subject to the conditions set forth herein.

     NOW, THEREFORE, in consideration of the mutual promises set forth herein,
the receipt and sufficiency of which are hereby acknowledged, the parties hereto
agree as follows:

     1.   SATISFACTION OF DEBT. Subject to the terms and conditions of this
          --------------------
Agreement, Digate shall pay to the Company, and the Company agrees to accept as
full payment of all of Digate's outstanding obligations under the Note,
$307,959.05 (the "Payoff Amount"), which amount represents the principal and
interest outstanding under the Note.

     2.   CLOSING.
          -------

          (a)  The transfer of the Payoff Amount as full payment of all of
Digate's outstanding obligations under the Note shall occur at the principal
office of the Company simultaneously with the execution of this Agreement by the
parties or on such other date as the Company and Digate shall agree (the
"Closing Date").
 ------------

          (b)  On the Closing Date,

               (i)  Digate shall deliver to the Company a negotiable instrument
effecting the transfer of the Payoff Amount to the Company;

               (ii) the Company shall deliver a letter to First Albany

               (iii) the Company shall cancel the Note and deliver the cancelled
Note to Digate.

against the other relating to or arising under the Pledge Agreement or the Note.

     5.   RELEASE OF UNKNOWN CLAIMS. The Company and Digate intentionally and
          -------------------------
voluntarily waive and relinquish the benefits of any statutes or decisions
providing that a general release does not extend to claims which the creditor
does not know or suspect to exist in its favor at the time of executing the
release, which if known by it must have materially affected its settlement with
the debtor.

     6.   NO ASSIGNMENTS OF RELEASED CLAIMS. The Company and Digate represent
          ---------------------------------

and warrant that they have not previously assigned or transferred, nor will they
assign or transfer, any claim, demand, or cause of being released by them in
this Agreement.
