                              STATEMENT OF PURPOSE

to permit the Borrower to increase the amount of its present investment in a

certain Debt of the Joint Venture.

        The Lenders have agreed to amend the Credit Agreement, but only on the

                acceptable to the Agent, of up to $37,500,000 of Debt
                obligations of a corporation (the "Joint Venture") formed and

amount of the Borrower's Debt in connection with the Credit Agreement, the Joint
Venture Guarantee shall be valued at $37,500,000.

               (b) The parties hereto agree that until such time as the Joint
Venture Guarantee is released or the underlying Debt subject to such Joint
Venture Guarantee is paid in full, the aggregate principal amount of all Loans
(after giving effect to any amount requested) shall not exceed the lesser of (i)
the Aggregate Commitment LESS $37,500,000 and (ii) the Earnings Multiple LESS

        5. LIMITED AMENDMENT. Except as expressly amended herein, the Credit
Agreement and each other Loan Document shall continue to be, and shall remain,
in full force and effect. This Sixth Amendment shall not be deemed (a) to be a
waiver of, or consent to, or a modification or amendment of, any other term or
condition of the Credit Agreement or any other Loan Documents or (b) to
prejudice any other right or rights which the Agent or Lenders may now have or
may have in the future under or in connection with the Credit Agreement or the
Loan Documents or any of the instruments or agreements referred to therein, as
the same may be amended, restated or otherwise modified from time to time.
