ARTICLE VIII
GUARANTEE

With respect to the Notes, but only in relation to the Notes, the provisions of this Article shall preempt, and be substituted for, the provisions of Article Sixteen of the Original Indenture in their entirety.

“Section 16.01. Guarantee. Except as otherwise provided herein, the Guarantors hereby jointly and severally and fully and unconditionally guarantee to each Holder of a Note authenticated and

delivered by the Trustee, and to the Trustee on behalf of such Holder, the due and punctual payment of the principal of, premium, if any, and interest, if any, on, the Notes and all other obligations of the Company under this Indenture, including all obligations hereunder of the Company to the Trustee, when and as the same shall become due and payable, whether at the stated maturity, by acceleration, call for redemption, upon a repurchase date or otherwise, in accordance with the terms of the Notes and of this Indenture. In case of the failure of the Company punctually to make any such payment, the Guarantors hereby agree to cause such payment to be made punctually when and as the same shall become due and payable, whether at the stated maturity or by acceleration, call for redemption, upon a repurchase date or otherwise, and as if such payment were made by the Company. The Guarantors agree that its obligations hereunder shall be absolute and unconditional, irrespective of, and shall be unaffected by, the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same or any release (other than by operation of Article Thirteen), amendment, waiver or indulgence granted to the Company or the Guarantors or any consent to departure from any requirement of any other guarantee of all or any of the Notes or any other circumstances which might otherwise constitute a legal or equitable discharge or defense of a surety or guarantor. The Guarantors hereby waive the benefits of diligence, presentment, demand for payment, any requirement that the Trustee or any of the Holders protect, secure, perfect or insure any security interest in or other lien on any property subject thereto or exhaust any right or take any action against the Company or any other Person or any collateral, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest or notice with respect to the Notes or the Indebtedness evidenced thereby and all demands whatsoever, and covenant that this Guarantee will not be discharged in respect of the Notes except by complete performance of the obligations contained in the Notes and in such Guarantee or the operation, as applicable, of Article Thirteen. The Guarantors agree that if, after the occurrence and during the continuance of an Event of Default, the Trustee or any of the Holders are prevented by applicable law from exercising their respective rights to accelerate the maturity of the Notes, to collect any principal of, or, interest or premium, if any, on, the Notes, or to enforce or exercise any other right or remedy with respect to the Notes, the Guarantors agree to pay to the Trustee for the account of the Holders, upon demand therefor, the amount that would otherwise have been due and payable had such rights and remedies been permitted to be exercised by the Trustee or any of the Holders.

The Guarantors shall be subrogated to all rights of the Holders of the Notes upon which its Guarantee is endorsed against the Company in respect of any amounts paid by the Guarantors on account of the Notes pursuant to the provisions of its Guarantee or this Indenture; provided, however, that the Guarantors shall not be entitled to enforce or to receive any payment arising out of, or based upon, such right of subrogation until the principal of, and premium, if any, and interest, if any, on, all Notes issued hereunder shall have been paid in full.

This Guarantee shall remain in full force and effect and continue to be effective should any petition be filed by or against the Company for liquidation or reorganization, should the Company become insolvent or make an assignment for the benefit of creditors or should a receiver or trustee be appointed for all or any part of the Company’s assets, and shall, to the fullest extent permitted by law, continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the Notes, is, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by any holder of the Notes, whether as a “voidable preference,” “fraudulent transfer,” or otherwise, all as though such payment or performance had not been made. In the event that any payment, or any part thereof, is rescinded, reduced, restored or returned, the Notes shall, to the fullest extent permitted by law, be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned.

Any term or provision of this Guarantee to the contrary notwithstanding, the aggregate amount of the obligations guaranteed hereunder shall be reduced to the extent necessary to prevent this Guarantee from violating or becoming voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally.

Section 16.02 Release of Guarantee.

6.10% Senior Notes due 2017

THIS DEBT SECURITY IS A GLOBAL DEBT SECURITY WITHIN THE MEANING OF THE INDENTURE HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF A DEPOSITARY OR NOMINEE THEREOF. THIS GLOBAL DEBT SECURITY MAY NOT BE EXCHANGED IN WHOLE OR IN PART FOR A SECURITY REGISTERED, AND NO TRANSFER OF THIS GLOBAL DEBT SECURITY IN WHOLE OR IN PART MAY BE REGISTERED, IN THE NAME OF ANY PERSON OTHER THAN SUCH DEPOSITARY OR A NOMINEE THEREOF, EXCEPT IN THE LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE.

Capitalized terms used herein shall have the meanings assigned to them in the Indenture referred to below unless otherwise indicated.

1. Interest. ▇▇▇▇▇▇ US, Inc., a Delaware corporation (the “Company” or the “Issuer”), promises to pay interest on the principal amount of this Note at 6.10% per annum from ___, 2007 until maturity. The Issuer shall pay interest semi-annually on January 1 and July 1 of each such year, or if any such day is not a Business Day, on the next succeeding Business Day (each an “Interest Payment Date”). Interest on the Notes shall accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance; provided that if there is no existing Default in the payment of interest, and if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; provided, further, that the first Interest Payment Date shall be January 1, 2008. The Issuer shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, from time to time on demand at the same rate, and it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace periods) from time to time on demand at the same rate to the extent lawful; and each type of interest referred to in this sentence shall hereinafter be referred to as “Defaulted Interest”. Interest shall be computed on the basis of a 360-day year of twelve 30-day months.

2. Method of Payment. (a) The Issuer shall pay interest on the Notes (except Defaulted Interest) to the Persons who are registered Holders of Notes at the close of business on the December 15 and June 15 immediately preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in Paragraph 2(b) of this Note with respect to Defaulted Interest, and the Issuer shall pay principal (and premium, if any) of the Notes upon surrender thereof to the Trustee or a paying agent on or after the Stated Maturity thereof. The Notes shall be payable as to principal, premium, if any, and interest at the office or agency of the Trustee maintained for such purpose (which initially is c/o Deutsche Bank Trust Company Americas, ▇▇ ▇▇▇▇ ▇▇▇▇▇▇, ▇▇^▇▇ ▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ 10005), or, at the option of the Issuer, payment of interest may be made by check mailed to the Holders at their addresses set forth in the register of Holders, and provided that payment by wire transfer of immediately available funds shall be required with respect to principal of, and interest and premium, if any, on, (1) each Global Debt Security and (2) all other Notes aggregating at least $1,000,000 in principal amount the Holder of which shall have provided wire transfer instructions to the Issuer or the paying agent on or prior to the applicable record date. Such payment shall

A-2

be 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.

(b) Any Defaulted Interest on any Note shall forthwith cease to be payable to the Holder thereof on the relevant record date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Issuer, at its election in each case, as provided in clause (i) or (ii) below.

(i) The Issuer may elect to make payment of any Defaulted Interest to the Persons whose names are registered at the close of business on a special record date for the payment of such Defaulted Interest, which shall be fixed in the following manner: The Issuer shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each such Note and the date of the proposed payment, and at the same time the Issuer shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Trustee shall fix a special record date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Issuer of such special record date and, in the name and at the expense of the Issuer, shall cause notice of the proposed payment of such Defaulted Interest and the special record date therefor to be mailed, first class postage prepaid, to each Holder thereof at its address as it appears in the Note register, not less than 10 days prior to such special record date. Notice of the proposed payment of such Defaulted Interest and the special record date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Notes are registered at the close of business on such special record date.

(ii) The Issuer may make payment of any Defaulted Interest on the Notes in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Registered Securities of such series may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Issuer to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.

3. Paying Agent and Registrar. Initially, Deutsche Bank Trust Company Americas, the Trustee under the Indenture, shall act as paying agent and Registrar. The Issuer may change any paying agent or Registrar without notice to any Holder. The Issuer may act in any such capacity.

4. Indenture. The Issuer issued the Notes under an Indenture dated as of June 18, 2007 (as amended (in accordance with its applicable provisions) by supplements and amendments of general application thereto, the “Original Indenture”), as supplemented by the First Supplemental Indenture dated as of June 18, 2007 (the “Supplemental Indenture”, and together with the Original Indenture, the “Indenture”), between the Issuer, ▇▇▇▇▇▇ Parent, the Subsidiary Guarantors and the Trustee. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S. Code §§ 77aaa-77bbbb). The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. To the

A-3

extent any provision of this Note conflicts with the provisions of the Indenture, the provisions of this Note shall govern and be controlling. The Notes are the obligation of the Issuer, initially in aggregate principal amount of $300.0 million. The Issuer may issue an unlimited aggregate principal amount of Additional Notes under the Indenture. Any such Additional Notes that are actually issued shall be treated as issued and outstanding Notes (and as the same series (with identical terms other than with respect to the issue date, issue price and first payment of interest) as the initial Note for the purposes indicated in Section 3.02 of the Supplemental Indenture). Initially, the Notes are guaranteed by ▇▇▇▇▇▇ Parent and the Subsidiary Guarantors named in the Supplemental Indenture.

5. Optional Redemption. (a) At its option, the Issuer may choose to redeem all or any portion of the Notes, at once or from time to time.

(b) To redeem the Notes, the Issuer must pay a redemption price equal to the greater of (i) 100% of the principal amount of the Notes to be redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal and interest on the Notes to be redeemed (excluding interest accrued to the redemption date of such Notes) discounted to such redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below) plus 15.0 basis points, plus, in each case, accrued and unpaid interest, if any, to the redemption date of such Notes (subject to the right of Holders on the relevant record date to receive interest due on the relevant Interest Payment Date).

For purposes of determining the redemption price, the following definitions shall apply:

“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent as having a maturity comparable to the remaining term of the Notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate notes of comparable maturity to the remaining term of the Notes to be redeemed.

“Comparable Treasury Price” means, with respect to any redemption date for the Notes, (i) the average of four Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest such Reference Treasury Dealer Quotations, or (ii) if the Trustee obtains fewer than six such Reference Treasury Dealer Quotations, the average of all such quotations, or (iii) if only one Reference Treasury Dealer Quotation is received, such quotation.

“Quotation Agent” means the Reference Treasury Dealer appointed by the Issuer.

“Reference Treasury Dealer” means (i) Banc of America Securities LLC (or its affiliates that are Primary Treasury Dealers) and its (and their) successors; provided, however, that if the foregoing shall cease to be a primary U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”), the Issuer will substitute therefor another Primary Treasury Dealer, and (ii) any other Primary Treasury Dealer selected by the Issuer.

“Reference Treasury Dealer Quotations” means, for each Reference Treasury Dealer and any redemption date of the Notes, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding such Redemption Date.

A-4

“Treasury Rate” means, with respect to any redemption date of the Notes, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date.

6. Mandatory Redemption and Sinking Fund; Repurchases. The Issuer shall not be required to make mandatory redemption or sinking fund payments with respect to the Notes. The Issuer shall be required to make an offer to repurchase Notes as provided in Section 5.01 of the Supplemental Indenture.

7. Notice of Redemption. Notice of redemption shall be mailed at least 30 days but not more than 60 days before the redemption date to each Holder whose Notes are to be redeemed at its registered address. Notes in denominations larger than $1,000 may be redeemed in part but only in whole multiples of $1,000, unless all of the Notes held by a Holder are to be redeemed. On and after the Redemption Date interest shall cease to accrue on Notes or portions thereof called for redemption and with respect to which the redemption price has been paid.

8. Denominations, Transfer, Exchange. The Notes are in registered form without coupons in denominations of $1,000 and integral multiples of $1,000. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents, and the Issuer may require a Holder to pay any taxes or other governmental charges imposed in relation thereto.

9. Persons Deemed Owners. The registered Holder of a Note shall be treated as its owner for all purposes.

10. Amendment, Supplement and Waiver. Subject to certain exceptions, the Indenture may be amended or supplemented with the consent of the Holders of not less than a majority in aggregate principal amount of the then Outstanding Notes, and any existing default or compliance with any provision of the Indenture relating to the Notes may be waived with the consent of the Holders of not less than a majority in aggregate principal amount of the then Outstanding Notes. Without the consent of any Holder of a Note, the Indenture may be amended or supplemented for any of the purposes set forth in Section 11.01 of the Indenture, including to cure any ambiguity, defect or inconsistency, to provide for the assumption of the Issuer’s obligations to Holders of the Notes in case of a merger or consolidation of the Issuer or sale of all or substantially all of the Issuer’s assets, to add or release Guarantors pursuant to the terms of the Indenture, to make any change that does not adversely affect the rights under the Indenture of any Holder of the Notes, to comply with the requirements of the SEC to permit the qualification of the Indenture under the Trust Indenture Act of 1939, to evidence or provide for the acceptance of appointment under the Indenture of a successor or separate Trustee, to add to the covenants of the Issuer or any Guarantor or to establish the form or terms of any other series of Debt Securities.

11. Defaults and Remedies. Events of Default with respect to the Notes include: (i) default for 30 days in the payment when due of interest on the Notes; (ii) default in payment when due of principal of or premium, if any, on the Notes when due at Stated Maturity, upon redemption, by declaration or otherwise; (iii) default for 30 days in the making of any payment when due for a sinking, purchase or similar fund provided for in respect to the Notes; (iv) failure by the Company or any Guarantor for 90 days after notice to comply with any of its other covenants or agreements in the

A-5

Indenture relating to the Notes; (v) except as permitted by the Indenture, the Guarantee of ▇▇▇▇▇▇ Parent ceasing to be in full force and effect or ▇▇▇▇▇▇ Parent denies or disaffirms its obligations under the Indenture or its Guarantee; and (vi) certain events of bankruptcy, insolvency or reorganization with respect to the Issuer or ▇▇▇▇▇▇ Parent. 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 may declare all the Notes to be due and payable. Notwithstanding the foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency, all Outstanding Notes shall become due and payable without further action or notice. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of not less than a majority in aggregate principal amount of the then Outstanding Notes may direct the Trustee in its exercise of any trust or power. If and so long as the Trustee in good faith so determines that withholding notice is in the interests of the Holders, the Trustee may withhold from Holders of the Notes notice of any continuing Default or Event of Default (except a Default or Event of Default relating to the payment of principal, premium, if any, or interest). The Holders of not less than a majority in aggregate principal amount of the Notes then Outstanding by written notice to the Trustee may on behalf of the Holders of all of the Notes waive any existing Default or Event of Default and its consequences under the Indenture except a continuing Default or Event of Default in the payment of interest on, the principal of, or premium, if any, on, the Notes. The Company is required to deliver to the Trustee annually a statement regarding compliance with the Indenture.

12. Trustee Dealings with Issuer. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Issuer or its affiliates, and may otherwise deal with the Issuer or its affiliates, as if it were not the Trustee.

13. No Recourse Against Others. The directors, officers, , incorporators, stockholders and other equity-interest owners, as such, past, present or future, of the Company or any Guarantor or any successor Person, either directly or indirectly through the Company or a Guarantor or any successor Person, whether by virtue of any constitution, statue or rule of law, or by the enforcement of any assessment or penalty or otherwise, shall have no liability for any obligations of the Issuer or any Guarantors under the Notes, the Indenture or the Guarantees or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Notes by accepting a Note expressly waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes.

14. Authentication. This Note shall not be valid until authenticated by the manual signature of the Trustee or an authenticating agent.

15. Abbreviations. Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act).

16. CUSIP and ISIN Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Issuer has caused CUSIP and, if applicable, corresponding ISIN numbers to be printed on the Notes, and the Trustee may use CUSIP and, if applicable, corresponding ISIN numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained

A-6

in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon.

The Issuer shall furnish to any Holder upon written request and without charge a copy of the Indenture. Requests may be made to:
