Section 2.01. Amendments to Indenture. Section 4.16. Section 4.16, Financial Reports, of the Indenture is hereby amended to:

(a) delete the last paragraph of Section 4.16(a) in its entirety; and

(b) insert the following new clause (f) at the end of such Section 4.16 immediately after clause (e):

“(f) Notwithstanding the foregoing, the reports required to be provided pursuant to clause (a) above may be those of the Parent Guarantor rather than those of the Company or the Co-Issuer so long as the Parent Guarantor’s Note Guaranty remains in effect. The Issuers shall be deemed to have provided all required reports and information of the Parent Guarantor to the Trustee and the Noteholders as required by this Section 4.16 if the Parent Guarantor has filed such reports and information with the SEC via the EDGAR filing system and such reports are publicly available. In the event the Parent Guarantor is no longer subject to the filing requirements of the Exchange Act, the Parent Guarantor shall not be required to file such reports with the SEC but the Issuers shall be deemed to have satisfied the obligations under this Section 4.16(f) if the Issuers post such reports and information of the Parent Guarantor on a publicly available website or on Intralinks or any comparable password protected online data system that may require a confidentiality acknowledgement; provided, that the Issuers shall make readily available any password or other login information to any Noteholder. So long as the Parent Guarantor’s Note Guaranty remains in effect, no reports or other information of the Company, the Co-Issuer, any Guarantor (other than the Parent Guarantor) or any other Subsidiary of the Company shall be required to be provided pursuant to this Section 4.16 to the Trustee, any Noteholder or any other Person.”

Section 4.01. Trustee Makes No Representation. The Trustee shall not be responsible in any manner whatsoever for or with respect to any of the recitals or statements contained herein, all of which recitals or statements are made solely by the Issuers, and the Trustee makes no representation with respect to any such matters. Additionally, the Trustee makes no representation as to the validity or sufficiency of this Supplemental Indenture.
