Banks parties to this Consent and Waiver hereby:

        (a)     (i) consent to the execution and delivery of the Merger
        Agreement, provided that

                        (A)     such consent shall not extend to the
                consummation of such merger,

                        (B)     consummation of such merger must either fully

                Agreement in accordance with the terms of such Credit Agreement,

                        (C)     any failure to consummate such merger by the
                Borrower shall not cause any payment penalty or other adverse
                consequence to the Borrower or any of it Subsidiaries, and

                        (D)     any breach, default or other non-compliance by
                the Borrower of any term or provision of the Merger Agreement
                shall not cause any payment penalty or other adverse consequence
                to the Borrower or any of it Subsidiaries (other than
