              ----------------------------------------

Dear Mr. Schoenbart:

         Reference is made to the  Promissory  Note ("Note")  dated November 20,
2001 made by PWR  Systems,  Inc.  ("Borrower")  in favor of JPMorgan  Chase Bank
("Bank") in the original principal amount of $1,214,171.88.  The Note is due and
payable in full on May 31, 2002, and as of May 30, 2002, the principal amount of
$1,104,171.88  remains outstanding under the Note. The Bank has agreed to modify
the  Note  and  extend  the  term  thereof,   pursuant  to  Modification  No.  1
(substantially  in the form annexed hereto) to be executed  between the Bank and
the Borrower (the "Note Modification").

         In  consideration of the Bank's execution of a modification of the Note
and extension of the payments due under the Note in accordance with the terms of
the Note Modification, the Borrower has agreed to:

         1.       make a partial  prepayment of principal  under the Note in the
                  amount  of  $400,000   (the   "Harvard   Trademark   Payment")
                  contemporaneously  with the sale of the Harvard  Trademarks by
                  the Borrower to Harvard University; and

         2.       cause  Vizacom Inc. to have Serif Inc.  ("Serif")  make direct
                  payment due under its  (Serif's)  note to Vizacom  Inc. to the
                  Bank in accordance with the payment  instructions set forth in
                  the attached  letter of direction to Serif,  and in connection
                  therewith,  deliver  to the Bank a written  acknowledgment  by
                  Serif  of  its   agreement  to  make  such  direct   payments,
                  commencing  with the  payment due on July 15,  2002.  The Bank
                  acknowledges  that the Borrower  will receive a credit for the
                  full amount of each installment  paid by Serif,  which will be
                  applied against the immediately  succeeding  installments  due
                  under the Note.

         Accordingly,   the  Note  Modification  is  subject  to  the  foregoing
conditions.

         The Bank agrees that, contemporaneously with its receipt of the Harvard
Payment,  it will execute and deliver to Borrower all  agreements  and documents
