6. Modification and Waiver.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of all Securities at the time Outstanding to be affected, considered together as one class for this purpose (such Securities to be affected may be Securities of the same or different series and, with respect to any series, may comprise fewer than all the Securities of such series). The Indenture also contains provisions (i) permitting the Holders of a majority in principal amount of the Securities at the time Outstanding to be affected under the Indenture, considered together as one class for this purpose (such affected Securities may be Securities of the same or different series and, with respect to any particular series, may comprise fewer than all the Securities of such series), on behalf of the Holders of all Securities so affected, to waive compliance by the Company with certain provisions of the Indenture and (ii) permitting the Holders of a majority in principal amount of the Securities at the time Outstanding of any series to be affected under the Indenture (with each such series considered separately for this purpose), on behalf of the Holders of all Securities of such series, to waive certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security. For the purpose of this paragraph, the term “default” means, with respect to any Securities, any event which is, or after notice or lapse of time or both would become, an Event of Default or Covenant Breach in respect of such Securities.

7. Remedies.

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture. With respect to this Security, the only Events of Default are payment defaults that continue for 30 days and insolvency events, all as specified in the Indenture. Any other default under or breach of the Indenture or the Securities will not give rise to an Event of Default, whether after notice, the passage of time or otherwise.

As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default or Covenant Breach with respect to the Securities of this series, the Holders of not less than 25% in principal amount of the Securities of this series at the time Outstanding shall have made written request to the Trustee to institute

proceedings in respect of such Event of Default or Covenant Breach, as applicable, as Trustee and offered the Trustee indemnity reasonably satisfactory to it, and the Trustee shall not have received from the Holders of a majority in principal amount of Securities of this series at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein.

If so provided pursuant to the terms of any specific Securities, the above-referenced provisions of the Indenture regarding the ability of Holders to waive certain defaults, or to request the Trustee to institute proceedings (or to give the Trustee other directions) in respect thereof, may be applied differently with regard to such Securities.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and premium (if any) and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed. As used in this Section 7, the term “series” (and references to the Securities of a series) shall mean only Securities having the same CUSIP number.

8. Transfer and Exchange.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his or her attorney duly authorized in writing, and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.
