amount of $12.5 million for the period from August 29, 2006 through August 29,
2009, pursuant to an agreement dated August 28, 2006 (collectively, the “New
Swap Contracts”). The Borrower failed to timely deliver such notice to the

is signed by a Responsible Officer of a Credit Party shall be conclusively
presumed to have been authorized by all necessary corporate, partnership and/or
other action on the part of such Credit Party and such Responsible Officer shall
be conclusively presumed to have acted on behalf of such Credit Party.

          2.2          Clause (i) of Section 8.06(e) is amended and restated in

Stock or warrants, rights or options to acquire any such shares for cash solely;
provided that all such dividends or acquisition of shares for cash in any period
of four consecutive fiscal quarters (including the fiscal quarter in which any
such dividend or acquisition may be made) shall not exceed an amount equal to
sixty-six and two thirds percent (66.667%) of Consolidated EBITDA for the period
of four consecutive fiscal quarters as of the last day of the fiscal quarter
most recently ended, if the Consolidated Total Leverage Ratio, on a Pro Forma
Basis, is less than 2.5 to 1.0; and provided further that the Borrower may make
additional dividends or acquisitions of shares for cash in connection with the
issuance of Subordinated Debt otherwise permitted hereunder, in an amount up to

Revolving Termination Date then applicable hereunder and the dividend is made or
the shares are acquired substantially concurrently with the issuance of the
subject Subordinated Debt;

          2.3          Subsection (e) of Section 2.02 is amended and restated in
its entirety to read as follows:

           (e)           After giving effect to all Borrowings, conversions and

fees and expenses payable in connection with this Amendment.

          4.           Guarantor Acknowledgment. Each Guarantor acknowledges and
consents to all of the terms and conditions of this Amendment and agrees that

to reduce or discharge any Guarantor’s obligations under the Credit Documents.

          5.           Full Force and Effect. Except as modified hereby, all of
the terms and provisions of the Credit Agreement and the other Credit Documents
(including schedules and exhibits thereto) shall remain in full force and
effect.

number of counterparts, each of which when so executed and delivered shall be
deemed an original, and it shall not be necessary in making proof of this
Amendment to produce or account for more than one such counterpart. Delivery by
any party hereto of an executed counterpart of this Amendment by facsimile shall
