         Bank and Borrower agree to amend the Loan and Security Agreement
between them, dated as of September 27, 2002 (as amended, restated,

(collectively, the "Designated Default") hereby is waived. It is understood,
however, that the foregoing waiver of the Designated Default does not constitute
a waiver of the aforementioned covenant with respect to any other date or time
period, or of any other provision or term of the Loan Agreement or any related

                                        the following covenant as of the end of
                                        each month:

              Minimum Tangible
              Net Worth:                Parent (on a consolidated basis) shall

                                        less than $10,500,000 (the "Minimum

                                        each month, provided that, at the end of
                                        each fiscal quarter of the Borrower,
                                        commencing with the fiscal quarter
                                        ending March 31, 2003, the Minimum
                                        Tangible Net Worth requirement shall be
                                        increased by 100% of the net income of
                                        the Parent (on a consolidated basis) for
                                        such fiscal quarter, but the Minimum
                                        Tangible Net Worth requirement shall not
                                        increase to greater than $17,000,000.
                                        Said increased Minimum Tangible Net
                                        Worth requirement shall be effective as
                                        of the end of such fiscal quarter, and
                                        shall continue in effect thereafter. In
                                        no event shall the Minimum Tangible Net
                                        Worth requirement be decreased.

                                        totality, must also otherwise be

                                        Projections as required above is to be
                                        used by the Bank in order to establish
                                        certain financial covenant levels for
                                        later periods during the term of this
                                        Agreement; (y) such a process introduces
                                        uncertainty as to the amounts required
                                        for Borrower's financial covenant
                                        compliance in the future; and (z)
                                        regardless of any such uncertainty,

                                        later-established amounts.
