The Issuer initially appoints the DTC to act as Depositary with respect to the Global Notes.

The Issuer initially appoints the Trustee to act as the Note Registrar and Paying Agent and to act as Custodian with respect to the Global Notes.

The Issuer will require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal, premium or Additional Interest, if any, or interest on the Notes, and will notify the Trustee of any default by the Issuer in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Issuer at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Issuer or its Subsidiary) will have no further liability for the money. If the Issuer or a Subsidiary of the Issuer acts as Paying Agent, it will segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the Issuer, the Trustee will serve as Paying Agent for the Notes.

The redemption price (“ Redemption Price ”) will equal the greater of (i) 100% of the principal amount of the Notes to be redeemed or (ii) as determined by the Quotation Agent, the sum of the present values of the remaining scheduled payments of principal and interest thereon (not including any portion of such payments of interest accrued as of the Redemption Date) that would be due if the Notes matured on the Par Call Date, discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate plus 35 basis points (0.35% or thirty-five one-hundredths of one percent), plus, in each case, accrued and unpaid interest thereon to the Redemption Date; provided , however , that if the Redemption Date falls after a Record Date and on or prior to the corresponding interest payment date, the Issuer will pay the full amount of accrued and unpaid interest, if any, on such interest payment date to the Holder of record at the close of business on the corresponding Record Date (instead of the Holder surrendering its Notes for redemption). Notwithstanding the foregoing, if the Notes are redeemed on or after the Par Call Date, the Redemption Price will be equal to 100% of the principal amount of the Notes being redeemed plus unpaid interest, if any, accrued thereon to, but excluding, the Redemption Date.

Such mailing shall be by first class mail (unless sent by electronic transmission). The notice, if mailed in the manner herein provided, shall be conclusively presumed to have been duly given, whether or not the Holder receives such notice. In any case, failure to give such notice by mail or any defect in the notice to the Holder of any Note designated for redemption as a whole or in part shall not affect the validity of the proceedings for the redemption of any other Note.

On or prior to the Redemption Date specified in the notice of redemption given as provided in this Section 3.02 , the Issuer will deposit with the Paying Agent (or, if the Issuer is acting as its own Paying Agent, set aside, segregate and hold in trust as provided in Section 4.04 hereof) an amount of monies in immediately available funds sufficient to redeem on the Redemption Date all the Notes (or portions thereof) so called for redemption at the appropriate Redemption Price; provided , that if such payment is made on the Redemption Date, it must be received by the Paying Agent, by 11:00 a.m., New York City time, on such date. The Issuer shall be entitled to retain any interest, yield or gain on amounts deposited with the Paying Agent pursuant to this Section 3.02 in excess of amounts required hereunder to pay the Redemption Price.

If less than all of the outstanding Notes are to be redeemed, the Trustee shall select the Notes or portions thereof of the Global Note or the Notes in certificated form to be redeemed (in principal amounts of $2,000 and integral multiples of $1,000 in excess thereof), on a pro rata

20

basis or such other method the Trustee deems fair and appropriate or is required by the Depositary. The Notes (or portions thereof) so selected for redemption shall be deemed duly selected for redemption for all purposes hereof.

Section 3.03. Payment of Notes Called for Redemption by the Issuer . If notice of redemption has been given as provided in Section 3.02 hereof, the Notes or portion of Notes with respect to which such notice has been given shall become due and payable on the Redemption Date and at the place or places stated in such notice at the Redemption Price, and unless the Issuer shall default in the payment of such Notes at the Redemption Price, so long as Paying Agent holds funds sufficient to pay the Redemption Price of the Notes to be redeemed on the Redemption Date, then (a) such Notes will cease to be outstanding on and after the Redemption Date, (b) interest on the Notes or portion of Notes so called for redemption shall cease to accrue on and after the Redemption Date, (c) after 5:00 p.m., New York City time, on the second Business Day immediately preceding the Redemption Date (unless the Issuer shall default in the payment of the Redemption Price) and, except as provided in Section 7.05 and Section 11.02 hereof, such Notes will cease to be entitled to any benefit or security under this Indenture, and (d) the Holders of the Notes shall have no right in respect of such Notes except the right to receive the Redemption Price thereof.

In case an Event of Default has occurred (which has not been cured or waived), the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of its own affairs.

No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act or its own willful misconduct, except that:

(a) prior to the occurrence of an Event of Default and after the curing or waiving of all Events of Default which may have occurred:

(i) the duties and obligations of the Trustee shall be determined solely by the express provisions of this Indenture and the Trust Indenture Act, and the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Indenture and no implied covenants or obligations shall be read into this Indenture and the Trust Indenture Act against the Trustee; and

The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Guarantee set forth in this Indenture on behalf of the Guarantor.

Section 15.03. Limitation of Guarantor’s Liability; Certain Bankruptcy Events .

(a) The Guarantor, and by its acceptance hereof each Holder, hereby confirms that it is the intention of all such parties that the Guarantee Obligations of the Guarantor pursuant to its Guarantee not constitute a fraudulent transfer or conveyance for purposes of any Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law. To effectuate the foregoing intention, the Holders and the Guarantor hereby irrevocably agree that the Guarantee Obligations of the Guarantor under this Article 15 shall be limited to the maximum amount as shall, after giving effect to all other contingent and fixed liabilities of the Guarantor, result in the Guarantee Obligations of the Guarantor under the Guarantee not constituting a fraudulent transfer or conveyance.
