          Re:  Loan Facility

Gentlemen:

          This letter will serve to confirm and  memorialize  our  agreement  to
modify and extend the  $1,000,000  loan facility  arrangement  (the  "Facility")
being  provided by  Churchill  Consulting  ("Churchill")  to Vizacom  Inc.  (the
"Company"), as evidenced by that certain letter agreement, dated January 8, 2000
(the "Original Letter Agreement"),  between Churchill and the Company,  and that
certain Line of Credit Note,  dated  January 8, 2000 (the  "Original  Note" and,
collectively with the Original Letter Agreement, the "Original Loan Documents"),
of the Company, payable to Churchill and in the principal amount of $1,000,000.

          Our agreement to modify and extend the Facility is as follows:

                    1. Notwithstanding the terms of the Original Loan Documents,
     the Facility will terminate,  and Original Note will mature,  on January 7,
     2002 (the "Extended Termination Date");

                    2. The $1,000,000 draw down on the Facility,  which was made
     on February 17, 2000,  must be paid in full,  together with all accrued and
     unpaid interest due Churchill from the Company, on the earlier of (a) April
     17, 2000 or (b) three  business days  following  the  Company's  receipt of
     gross proceeds from any offering of equity  securities of the Company in an
     amount  equal  to  $2,000,000  or  more  (in  either  case,  the  "Original
     Repayment").

                    3. If the Original  Repayment is made in accordance with the
     terms of clause 2 above, and notwithstanding the terms of the Original Loan
     Documents,  Churchill will extend the Facility to the Extended  Termination
     Date  and,  during  the  period  commencing  on the  date  of the  Original
     Repayment  and through the date 180 days prior to the Extended  Termination
     Date,  the Company may,  from time to time and in whole or part,  draw down
     upon the Facility and repay amounts so drawn down; provided,  however, that
     at

<PAGE>

     no  time  will  the  principal  amount of loans under the  Facility  exceed
     $1,000,000.

                    4. After the Original  Repayment,  each and every drawn down
     on the  Facility  shall be due and  payable 180 days after the date of such
     draw down.

                    5. Except as specifically provided in this letter agreement,
     all of the terms and conditions of the Original Loan Documents shall remain
     in effect.

          If the  foregoing  accurately  sets forth our  agreement,  please sign
where indicated below.
