         PRELIMINARY STATEMENT

A.          Pursuant to that certain Loan  Agreement  dated as of September  18,
            1995,   between  the  Borrower  and  the  Lender,   the  Lender  has
            established  a line of  credit  in the  principal  amount  of  Three
            Hundred Thousand Dollars ($300,000.00) in favor of the Borrower (the
            "Line of Credit").  The Loan Agreement and other Borrower  Documents
            were originally between the Borrower and UniDial  Incorporated.  The
            Lender  acquired  the Loan from UniDial  Incorporated  on January 1,
            1997.

B.          The  obligation of the Borrower to repay the  outstanding  principal
            balance  of the  Line of  Credit,  together  with  accrued  interest
            thereon is  evidenced by that  certain  Revolving  Credit Note dated
            September 18, 1995,  made by the  Borrower,  payable to the order of
            the  Lender,  and in the face  principal  amount  of  Three  Hundred
            Thousand Dollars ($300,000.00),  as amended pursuant to that certain
            First Amendment to Revolving Credit Note dated March 1, 1997 between
            the Borrower and the Lender (the "First  Amendment")  (collectively,
            the "Note").

C.          The  obligation  of the Lender to  establish  the Line of Credit was
            subject to the condition,  among others,  that the Borrower  execute
            that certain  Security  Agreement dated September 18, 1995,  between
            Borrower and Lender ("Security Agreement")

D.          The current maturity date of the Note is January 31, 1998.

E.          The Borrower  has now  requested  that the Lender  extend the stated
            maturity date of the Line of Credit from January 31, 1998 to January
            31, 1999.  The Lender is willing to and desires to extend the stated
            maturity date of the Line of Credit from January 31, 1998 to January
            31,  1999,  pursuant to the terms and  conditions  set forth in this
            First  Amendment (the term "Loan  Agreement,"  as hereinafter  used,
            includes  this  First  Amendment  and  all  future   amendments  and
            modifications to the Loan Agreement).

            authorized,  issued and outstanding  shares of the Borrower's common

            Shareholders will receive from the extension of the maturity date of
            the Note, the  Shareholders are willing to and desire to execute and
            deliver this First  Amendment to Stock Pledge  Agreement in favor of
