     WHEREAS, the Holders of a majority in aggregate principal amount of the Notes outstanding have duly consented to the proposed modifications set forth in this Supplemental Indenture in accordance with Section 9.02 of the Indenture;

ARTICLE ONE
AMENDMENTS

Section 1.01 Amendments.

     (a) Subject to Section 2.01 hereof, the Indenture is hereby amended by deleting in their entireties Sections 4.03, 4.04, 4.05, 4.06, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.14, 4.15, 4.16, 4.17, 4.18, 8.03 and 8.04 and Article V of the Indenture. Effective as of the date hereof, none of the Company, any Guarantor, the Trustee or other parties to or beneficiaries of the Indenture shall have any rights, obligations or liabilities under such Sections or Article, and such Sections or Article shall not be considered in determining whether an Event of Default has occurred or whether the Company or any Guarantor has observed, performed or complied with the provisions of the Indenture.

     (b) Subject to Section 2.01 hereof, Sections 6.01 and 6.02 of the Indenture are hereby amended and restated to read, in their respective entireties, as follows:

          “Section 6.01. Events of Default.

     Each of the following is an “Event of Default”:

     (1) default in any payment of interest on, or Liquidated Damages, if any, with respect to any Note under the Indenture when due, continued for 30 days;

     (2) default in the payment when due (at maturity, upon redemption or otherwise) of the principal of, or premium, if any, on, the Notes; or

     (3) failure by the Company of any of its Restricted Subsidiaries for 60 days after notice to the Company by the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding voting as a single class to comply with any of the other agreements in this Indenture or the Notes.

          Section 6.02. Acceleration.

     If any Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes by written notice to the Company may declare all the Notes to be due and payable immediately.

     Upon any such declaration, the Notes shall become due and payable immediately.

     The Holders of a majority in aggregate principal amount of the then outstanding Notes by written notice to the Trustee may, on behalf of all of the Holders, rescind an acceleration and its consequences, if the rescission would not conflict with any judgment or decree and if all existing Events of Default (except

nonpayment of principal, interest or premium or Liquidated Damages, if any, that has become due solely because of the acceleration) have been cured or waived.”

     Section 1.02 Amendment of Definitions. Subject to Section 2.01 hereof, the Indenture is hereby amended by deleting any definitions from the Indenture with respect to which references would be eliminated as a result of the amendments of the Indenture pursuant to Section 1.01 hereof.
