In no event will the maturity of the Series 2007C Notes be extended beyond the Final Maturity Date.

To make an election to extend the maturity of an Extendible Note effective on any Election Date, a Holder must deliver a notice of election during the Notice Period for that Election Date, such notice to be substantially in the form entitled “Notice of Election to Extend Maturity” attached to Exhibit A hereto, duly completed (a “Notice of Election”), and in the event of an election to the extend the maturity of only a portion of the principal amount of such Xxxxxx’s Extendible Note, such Extendible Note. The Notice Period for each Election Date will begin on the fifth Business Day prior to the Election Date and will end at the close of business, New York City time, on the Election Date (the “Notice Period”). If the Election Date is not a Business Day, the Notice Period will be extended to the Business Day next following the Election Date.

1810688_2.DOC

Business Day in the Notice Period relating to the applicable Election Date. Upon delivery to the Trustee of a Notice of Election to extend the maturity of a Holder’s Extendible Note or any portion thereof during any Notice Period, that Notice of Election will be revocable during each day of such Notice Period, until 12:00 noon, New York City time, on the last Business Day in the Notice Period relating to the applicable Election Date, at which time such Notice of Election will become irrevocable.

If on any Election Date, a Holder of an Extendible Note does not make a timely and proper election to extend the maturity of all or any portion of the principal amount of such Holder’s Extendible Note, the principal amount of such Extendible Note for which no such election has been made will be due and payable at the Stated Maturity of such Extendible Note. The principal amount of an Extendible Note for which no election to extend the maturity has been made on any Election Date will be represented by a substitute non-extendible note deemed to be issued as of such Election Date, substantially in the form of Exhibit B hereto (a “Substitute Note”) and Schedule A to such Extendible Note shall be annotated as of such Election Date to reflect the corresponding decrease in the principal amount thereof. If a Holder of an Extendible Note elects to extend the maturity of only a portion of an Extendible Note, the principal amount of the Substitute Note must be in an authorized denomination as provided in Section 105. The Substitute Note so issued will have the same terms as the original Extendible Note, except that it will not be extendible, it will have a different CUSIP number and its maturity date will remain the Stated Maturity. Interest on the Substitute Note shall accrue from and including the last Interest Payment Date on the related original Extendible Note. The Company and the Trustee shall deem an Extendible Note canceled as to any portion of the principal amount thereof for which a duly completed Notice of Election and, if applicable, such Extendible Note, are not delivered to the Trustee within the Notice Period for any Election Date, except with respect to the entitlement of any interest thereon that is in arrears as of such Election Date.

A Holder’s failure to elect to extend the maturity of all or any portion of the Series 2007C Notes will be irrevocable and will be binding upon any subsequent Holder of such Series 2007C Notes.

The unpaid principal amount of the Series 2007C Notes shall accrue interest at the Coupon Rate set monthly pursuant to Section 104 hereof, from the Original Issue Date, until paid or duly provided for. Interest shall be paid monthly in arrears on each Interest Payment Date to the Person in whose name such Series 2007C Note is registered on the Regular Record Date for such Interest Payment Date, whether or not such Regular Record Date is a Business Day. However, interest payable on the Stated Maturity of any Series 2007C Note will be paid to the same Person to whom the principal is payable. The initial Interest Payment Date for the Series 2007C Notes is July 18, 2007. The final Interest Payment Date for a Series 2007C Note shall be the Stated Maturity for that Series 2007C Note. Any such interest that is not so punctually paid or duly provided for will forthwith cease to be payable to the Holders on such Regular Record Date and may either be paid to the Person or Persons in whose name the Series 2007C Notes are registered at the close of business on a Special Record Date for the payment of such defaulted interest to be fixed by the Trustee, notice whereof shall be given to Holders of the Series 2007C Notes not less than ten (10) days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange, if any, on

1810688_2.DOC

which the Series 2007C Notes shall be listed, and upon such notice as may be required by any such exchange, all as more fully provided in the Original Indenture.

The rate at which interest shall accrue on the unpaid principal amount of the Series 2007C Notes for each Interest Period shall be the relevant Coupon Rate for that Interest Period and payments of interest on the Series 2007C Notes will include interest accrued to but excluding the respective Interest Payment Dates. Such interest shall accrue on the basis of the actual number of days in each Interest Period and a year of 360 days.

Interest on the Series 2007C Notes will be payable, in arrears, on each Interest Payment Date, including any Interest Payment Date on which a Holder elects to extend the maturity of any Extendible Note in accordance with the provisions of this Section 103. In the event any Interest Payment Date is not a Business Day, then the Interest Payment Date will be the next succeeding day which is a Business Day, unless:

(i) that next succeeding Business Day falls in the next succeeding calendar month; or

(ii) the Interest Payment Date that does not occur on a Business Day is also the scheduled Stated Maturity for such Series 2007C Note,

in which case, the relevant Interest Payment Date or Stated Maturity for the relevant Series 2007C Note, as the case may be, will be the immediately preceding Business Day and interest will accrue to but excluding that immediately preceding Business Day.

Payments of the principal and interest due at the Stated Maturity of any Series 2007C Notes shall be made upon surrender of such Series 2007C Notes at the Corporate Trust Office of the Trustee. The principal of and interest on the Series 2007C Notes shall be paid in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. Payments of interest (including interest on any Interest Payment Date) will be made, subject to such surrender where applicable, at the option of the Company, (i) by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register or (ii) by wire transfer or other electronic transfer at such place and to such account at a banking institution in the United States as may be designated in writing to the Trustee at least sixteen (16) days prior to the date for payment to the Person entitled thereto.

SECTION 104. Determination of Interest Rate. The Series 2007C Notes will accrue interest for each Interest Period at a per annum rate, subject to a maximum interest rate permitted by New York or other applicable state law, as such law may be modified by United States law of general application (the “Coupon Rate”). The Coupon Rate shall be equal to LIBOR for each Interest Period, as determined by the Calculation Agent, plus the Applicable Spread.

Promptly upon such determination, the Calculation Agent will notify the Company and the Trustee, if the Trustee is not then serving as the Calculation Agent, of the Coupon Rate for the new Interest Period. All calculations made by the Calculation Agent for the purposes of calculating the interest rates on the Series 2007C Notes shall be conclusive and binding upon the

1810688_2.DOC

beneficial owners and Holders of the Series 2007C Notes, the Company and the Trustee, absent manifest error.

Upon the request of a Holder of the Series 2007C Notes, the Calculation Agent will provide to such Holder the interest rate in effect on the date of such request and, if determined, the interest rate for the next Interest Period.

SECTION 105. Denominations. The Series 2007C Notes may be issued in denominations of $1,000, or any integral multiple thereof.

SECTION 106. Global Securities. The Series 2007C Notes will be issued in the form of one or more Global Securities registered in the name of the Depositary (which shall be The Depository Trust Company) or its nominee. Except under the limited circumstances described below, Series 2007C Notes represented by one or more Global Securities will not be exchangeable for, and will not otherwise be issuable as, Series 2007C Notes in definitive form. The Global Securities described above may not be transferred except by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or a successor Depositary or its nominee.

Owners of beneficial interests in such a Global Security will not be considered the Holders thereof for any purpose under the Indenture, and no Global Security representing a Series 2007C Note shall be exchangeable, except for another Global Security of like denomination and tenor to be registered in the name of the Depositary or its nominee or to a successor Depositary or its nominee. The rights of Holders of such Global Security shall be exercised only through the Depositary.

Subject to the procedures of the Depositary, a Global Security shall be exchangeable for Series 2007C Notes registered in the names of persons other than the Depositary or its nominee only if (i) the Depositary notifies the Company that it is unwilling or unable to continue as a Depositary for such Global Security and no successor Depositary shall have been appointed by the Company, or if at any time the Depositary ceases to be a clearing agency registered under the Securities Exchange Act of 1934, as amended, at a time when the Depositary is required to be so registered to act as such Depositary and no successor Depositary shall have been appointed by the Company, in each case within 90 days after the Company receives such notice or becomes aware of such cessation, (ii) the Company in its sole discretion determines that such Global Security shall be so exchangeable, or (iii) there shall have occurred an Event of Default with respect to the Series 2007C Notes. Any Global Security that is exchangeable pursuant to the preceding sentence shall be exchangeable for Series 2007C Notes registered in such names as the Depositary shall direct.

Neither the Company, the Trustee nor any agent of the Company or the Trustee shall have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in a Global Security, for maintaining, supervising or reviewing any records relating to such beneficial ownership interests or for any delay in exercising the option to extend the maturity of an Extendible Note.

1810688_2.DOC

SECTION 107. Transfer. No service charge will be made for any transfer or exchange of Series 2007C Notes, but payment will be required of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection therewith.

SECTION 108. Redemption. The Series 2007C Notes will not be redeemable by the Company prior to Stated Maturity.

Except as provided in the next succeeding sentence, the Stated Maturity will be the Initial Maturity Date. A Holder of the Series 2007C Notes may elect to extend the maturity of all of the principal amount of its Series 2007C Notes or any portion of its Series 2007C Notes having a principal amount of $1,000 or any integral multiple thereof, during the Notice Period (as defined below) relating to each Election Date (as defined below), in which case the maturity of such principal amount of its Series 2007C Notes shall be extended to the date occurring 366 calendar days from and including the 18th calendar day of the next succeeding month from such Election Date (or, if such date is not a Business Day, the immediately preceding Business Day).

To make an election to extend the maturity of this Note effective on any Election Date, a Holder must deliver a notice of election during the Notice Period for that Election Date, such notice to be substantially in the form entitled “Notice of Election to Extend Maturity” attached hereto, duly completed (a “Notice of Election”), and in the event of an election to extend the maturity of only a portion of the principal amount of this Note, this Note.

The principal amount of this Note for which no election to extend the maturity has been made on any Election Date will be represented by a substitute, non-extendible note deemed to be issued as of such Election Date, substantially in the form of Exhibit B to the Thirtieth Supplemental Indenture to the Indenture referred to on the reverse hereof (a “Substitute Note”) and Schedule A hereto shall be annotated as of such Election Date to reflect the corresponding decrease in the principal amount hereof.

Substitute Note so issued will have the same terms as this Note, except that it will not be extendible, it will have a different CUSIP number and its non-extendible maturity date will remain the Stated Maturity. Interest on the Substitute Note shall accrue from and including the last Interest Payment Date on the related original Note. The Company and the Trustee shall deem this Note canceled as to any portion of the principal amount hereof for which a duly completed Notice of Election and, if applicable, this Note, are not delivered to the Trustee within the Notice Period, except with respect to the entitlement to any interest thereon that is in arrears as of the Election Date.

A Holder’s failure to elect to extend the maturity of all or any portion of this Note will be irrevocable and will be binding upon any subsequent Holder of this Note.

The rate at which interest shall accrue on the unpaid principal amount of this Note for each Interest Period (as defined below) shall be the relevant Coupon Rate (as defined below) for that Interest Period and payments of interest on the Series 2007C Notes will include interest accrued to but excluding the respective Interest Payment Dates. Such interest shall accrue on the basis of the actual number of days in each Interest Period and a year of 360 days.

The Series 2007C Notes will accrue interest for each Interest Period at a per annum rate, subject to a maximum interest rate permitted by New York or other applicable state law, as such law may be modified by United States law of general application (the “Coupon Rate”). The Coupon Rate, as determined by the Calculation Agent, shall be equal to LIBOR (as defined below) for each Interest Period plus the Applicable Spread (as defined below).
