          “Section 1303. Covenant Defeasance.

respect to such Defeasible Covenant shall be deemed not to be or result in an Event of Default, in each case, with respect to the Outstanding Securities of such Series As provided in this Section 1303 on and after the date the conditions set forth in Section 1304 are satisfied (hereinafter called “Covenant Defeasance”). For this purpose, such Covenant Defeasance means that, with respect to the Outstanding Securities of such series, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such Defeasible Covenant, whether directly or indirectly by reason of any reference elsewhere herein to any Defeasible Covenant or by reason of any reference in any such Defeasible Covenant to any other provision herein or in any other document, but the remainder of this Indenture and such Securities shall be unaffected thereby. Following a Covenant Defeasance, payment of the Securities of such series may not be accelerated because of an Event of Default specified in Section 501(9) or Section 501(10) or by reference to Section 501(8) and such Defeasible Covenant.”

          Section 3. Notes. The parties hereto acknowledge that as provided in Sections 201, 202, 301, 303 and 308 of the Indenture, the Issuer, in exchange for the Series A Notes, Series B Notes and Series C Notes exchanged pursuant to the Exchange Offer, and originally issued under the Indenture, shall issue and the Trustee shall authenticate, the Exchange Notes that reflect the changed terms set forth in this Second Supplemental Indenture.

     3. Separability Clause. In case any provision in this Second Supplemental Indenture shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

     4. Modification, Amendment and Waiver. The provisions of this Second Supplemental Indenture may not be amended, supplemented, modified or waived, unless otherwise provided in the Indenture, except by the execution of a supplemental indenture executed by the Issuer, and, to the extent such amendment, supplement or waiver adversely affects the rights of any Holders, with the Required Consent of such Holders. Any such amendment or supplemental indenture shall comply with Article Nine of the Second Supplemental Indenture. Until an amendment, waiver or other action by Holders becomes effective, a consent thereto by a Holder of a Security hereunder is a continuing consent by the Holder and every subsequent Holder of that Security or portion of the Security that evidences the same obligation as the consenting Holder’s Security, even if notation of the consent, waiver or action is not made on the Security. After an amendment, waiver or action becomes effective, it shall bind every Holder.

     5. Ratification of Indenture; Second Supplemental Indenture Part of the 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. In the event of a conflict between the terms and conditions of the Indenture and the terms and conditions of this Second Supplemental Indenture, then the terms and conditions of this Second Supplemental Indenture shall prevail. This Second Supplemental Indenture shall form a part of the Indenture for all purposes, and every holder of Securities heretofore or hereafter authenticated and delivered shall be bound hereby.

     6. Trust Indenture Act Controls. If any provision of this Second Supplemental Indenture limits, qualifies or conflicts with any provision of the Trust Indenture Act of 1939, as amended (“TIA”), that is required under the TIA to be part of and govern any provision of this Second Supplemental Indenture, the provision of the TIA shall control. If any provision of this Second Supplemental Indenture modifies or excludes any provisions of the TIA that may be so modified or excluded, the provisions of the TIA shall be deemed to apply to the Indenture as so modified or to be excluded by this Second Supplemental Indenture, as the case may be.

     7. Governing Law. THIS SECOND SUPPLEMENTAL INDENTURE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, AS APPLIED TO CONTRACTS MADE AND PERFORMED WITHIN THE STATE OF NEW YORK WITHOUT GIVING EFFECT TO THE PRINCIPLES OF CONFLICTS OF LAW.

     9. Multiple Originals. The parties may sign any number of copies of this Second Supplemental Indenture. Each signed copy shall be an original, but all of them together represent the same agreement. One signed copy is enough to prove this Second Supplemental Indenture.

     10. Effect of Headings. The Section headings herein are for convenience only and shall not effect the construction thereof.

     11. Notices. Any request, demand, authorization, notice, waiver, consent or communication to any of the parties shall be made as set forth in Sections 105 and 106 of the Indenture.
