     2. The Lender hereby waives compliance by the Borrowers with their covenant
contained in Section 2.07 of the Credit Agreement as in effect prior to this
Amendment.

     C. Conditions. This Amendment shall not become effective until the date on

Note and duly executed Revolving Credit Note, each substantially in the form
attached hereto as Exhibit A and Exhibit B, respectively, and (ii) paid or
reimbursed the Lender for all of the Lender's costs and expenses, including a

conditions of the Agreement remain in full force and effect, without waiver or
modification. All terms defined in the Agreement shall have the same meaning
when used in this Amendment. This Amendment shall be effective upon delivery by
