                  other acquisition of, any shares of any class of Capital Stock
                  of the Borrower or any warrants or options to purchase any
                  such Stock, whether now or hereafter outstanding, or make any
                  other distribution in respect thereof, either directly or
                  indirectly, whether in cash or property or in obligations of
                  the Borrower or any Subsidiary (such declarations, payments,
                  setting apart, purchases, redemptions, defeasances,
                  retirements, acquisitions and distributions being herein
                  called "Restricted Payments"). Notwithstanding the foregoing,
                  however, the Borrower may:

                  (i)  repurchase the Capital Stock of the Borrower pursuant to
                       any currently existing or subsequently adopted stock
                       repurchase program without any limitations, provided,
                       that the ratio of Consolidated Senior Indebtedness to
                       Consolidated EBITDA as of the last day of any Rolling
                       Period (calculated on a pro forma basis as if such
                       repurchase of Capital Stock of the Borrower, and the
                       incurrence of any Indebtedness by any Loan Party in
                       connection therewith, had occurred immediately prior to
                       such day) is less than 1.0 to 1.0. From and after the
                       last day of any Rolling Period (beginning with the
                       Rolling Period ended immediately prior to the Closing
                       Date) for which the ratio of Consolidated Senior
                       Indebtedness to Consolidated EBITDA as of the last day of
                       any such Rolling Period (calculated on a pro forma basis
                       as if such repurchase of Capital Stock of the Borrower,
                       and the incurrence of any Indebtedness by any Loan Party
                       in connection therewith, had occurred immediately prior
                       to such day) is 1.0 to 1.0 or greater (such day, the
                       "Limitation Date"), the Borrower shall be subject to a
                       limitation of $15,000,000 in the aggregate for all such
                       repurchases of Capital Stock (the "Limitation") from and
                       after the Limitation Date. The Limitation described
                       previously shall not be applicable during any subsequent
                       Rolling Period in which the ration described herein for
                       such Rolling Period is less than 1.0 to 1.0. For any
                       subsequent Rolling Period in which the ratio described
                       herein for such Rolling Period is 1.0 to 1.0 or greater,
                       the Limitation shall again be $15,000,000 in the
                       aggregate from and after any such subsequent Rolling
                       Period, and

                  (ii) declare and pay cash dividends to its shareholders,
                       provided, that both prior to and after giving effect to
                       the payment of such dividends, (A) the Borrower is in pro
                       forma compliance with the financial covenants set forth
                       in Section 7.01 and (B) no Event of Default has occurred

amendment, modification or any other change to the Credit Agreement or the Loan
Documents or any rights or remedies arising in favor of the Lenders or the
Administrative Agent, or any of them, under or with respect to any such
documents or (d) to be a waiver of, or consent to or a modification or amendment

corporate action on the part of the Borrower and the Guarantors.

construed in accordance with the laws of the State of New York without regards
to conflicts of law principles.
