Guarantor under the Indenture.

                  Section 2.2. Guarantee. The New Note Guarantor hereby fully,
unconditionally and irrevocably guarantees, as primary obligor and not merely as

maturity, by acceleration, by redemption or otherwise, of the Obligations, all
as more fully set forth in Article IX of the Indenture.

                  Section 3.1. Notices. Any notice or communication delivered to
the Company under the provisions of the Indenture shall constitute notice to the

intended or shall be construed to give any Person, firm or corporation, other
than the Holders and the Trustee, any legal or equitable right, remedy or claim
under or in respect of this Supplemental Indenture, the Indenture or any
provision herein or therein contained.

extent of such invalidity, illegality or unenforceability.

                  Section 3.5. Ratification of Indenture; Supplemental Indenture
Part of Indenture. Except as expressly amended hereby, the Indenture is in all
respects ratified and confirmed and all the terms, conditions and provisions
thereof shall remain in full force and effect. This Supplemental Indenture shall
form a part of the Indenture for all purposes, and every Holder heretofore or
hereafter authenticated and delivered shall be bound hereby. The Trustee makes

Supplemental Indenture.

may sign any number of copies of this Supplemental Indenture. One signed copy is
enough to prove this Supplemental Indenture. This Supplemental Indenture may be

original, but all of them together represent the same agreement.
