the capital stock or other similar ownership interests in other Subsidiaries of
the Borrower and (ii) non-operating activities incidental thereto."

(a) Section 8.2.9(b) of the Credit Agreement is hereby amended by
deleting it in its entirety and substituting in lieu thereof the following new
text:

"(b) any Subsidiary may liquidate or dissolve voluntarily
into, and may merge with and into, the Borrower or any other
Subsidiary, and the assets or stock of any Subsidiary may be
purchased or otherwise acquired by the Borrower or any other

not a Pledged Entity, such Pledged Entity shall be the
continuing Person following such merger; provided, further,
that if any Subsidiary that is a Former Pledged Entity shall
merge with any other Subsidiary that is not a Pledged Entity
or a Former Pledged Entity, such Former Pledged Entity shall
be the continuing Person following such merger; provided,
further, that if any Subsidiary that is a Pledged Entity shall
liquidate or dissolve voluntarily into, or merge into, the
Borrower or any other Subsidiary, or all or substantially all
of the assets or stock of any such Subsidiary are purchased or
otherwise acquired by the Borrower or any other Subsidiary,
such assets of such Subsidiary shall be transferred (whether
by means of merger or otherwise) (i) to the Borrower (and
pledged by the Borrower as collateral security for the
Obligations) or (ii) to another Subsidiary that is a Pledged
Entity; and provided, further, that if any Subsidiary that is
a Former Pledged Entity shall liquidate or dissolve
voluntarily into, or merge into, the Borrower or any other
Subsidiary, or all or substantially all of the assets or stock
of any such Subsidiary are purchased or otherwise acquired by
the Borrower or any other Subsidiary, such assets of such
Subsidiary shall be transferred (whether by means of merger or
otherwise) (i) to the Borrower (and pledged by the Borrower as
collateral security for the Obligations), (ii) to another
Subsidiary that is a Pledged Entity or (iii) to another
Subsidiary that is a Former Pledged Entity;"

SECTION 8. Waiver of Section 8.2.9 (Consolidation, Merger, etc.). The
Agent and the Required Lenders hereby waive any violation of the second proviso
to Section 8.2.9(b) of the Credit Agreement occurring as a result of the

interests in any Former Pledged Entity to a Pledged Entity pursuant to the
restructuring transactions described in the Restructuring Waiver Request
attached hereto as Annex B (the "Restructuring Waiver Request").

executed copies of this Amendment and Waiver from the Required Lenders; (c) the

Credit Agreement to the extent that any entity has become a direct Subsidiary of
the Borrower as a result of the restructuring transactions described in the
Restructuring Waiver Request; (d) the Agent shall have received such other
documents as the Agent shall have reasonably requested; and (e) no Default or
Event of Default shall have occurred and be continuing on the date hereof after

warranties which speak as of a certain date, which representations and
warranties shall be true and correct in all material respect as of such date.

SECTION 12. Continuing Effect of Credit Agreement. This Amendment and
Waiver shall not constitute an amendment or waiver of any other provision of the
Credit Agreement or the Loan Documents not expressly referred to herein and
shall not be construed as a waiver or consent to any further or future action on
the part of the Borrower that would require a waiver or consent of the Agent
and/or the Lenders. Except as expressly amended or waived hereby, the provisions
of the Credit Agreement and the Loan Documents are and shall remain in full

BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK.

SECTION 15. Expenses. The Borrower agrees to pay or reimburse the Agent
for all of its out-of-pocket costs and expenses incurred in connection with the
