Unless otherwise provided in the 2025 Notes, all of the 2025 Notes shall be dated the date of their authentication.

Any of the 2025 Notes bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such 2025 Notes or did not hold such offices at the date of such 2025 Notes.

(b)                                 such 2025 Notes, when authenticated and delivered by the Trustee and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Company, enforceable in accordance with their terms, subject to bankruptcy, insolvency, moratorium, reorganization, and other laws of general applicability relating to or affecting the enforcement of creditors’ rights and to general principles of equity;

provided, however, that if all of the 2025 Notes issuable by or pursuant to a Board Resolution of the Company are not to be originally issued at one time, it shall not be necessary to deliver the Officers’ Certificate or Opinion of Counsel otherwise required pursuant to this paragraph at or prior to the time of authentication of such 2025 Notes if such documents are delivered at or prior to the time of authentication upon original issuance of such 2025 Notes to be issued. After the original issuance of such 2025 Notes to be issued, any separate request by the Company that the Trustee authenticate such 2025 Notes for original issuance will be deemed to be a certification by the Company that it is in compliance with all conditions precedent provided for in the Base Indenture and this Supplemental Indenture relating to the authentication and delivery of such 2025 Notes.

None of the 2025 Notes shall be entitled to any benefit under the Base Indenture or this Supplemental Indenture or be valid or obligatory for any purpose unless there appears on such 2025 Notes a certificate of authentication executed by the Trustee by manual signature of an authorized signatory, and such certificate upon any of the 2025 Notes shall be conclusive evidence, and the only evidence, that such 2025 Notes have been duly authenticated and delivered hereunder.

Section 2.07.  CUSIP Number.  The Company in issuing the 2025 Notes may use Committee on Uniform Security Identification Procedures (“CUSIP”) numbers (if then generally in use), and, if so, the Trustee will use CUSIP numbers in notices of redemption as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the 2025 Notes or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the 2025 Notes, and any such redemption will not be affected by any defect in or the omission of such numbers.  The Company will promptly notify the Trustee in writing of any change in the CUSIP numbers.

Section 2.08.  Issuance of Additional 2025 Notes.  The Company will be entitled, upon delivery of an Officer’s Certificate and an Opinion of Counsel, to issue Additional 2025 Notes under this Supplemental Indenture which will have identical terms as the Initial 2025 Notes issued on the date hereof, other than with respect to the date of issuance and issue price.  The Initial 2025 Notes issued on the date hereof and any Additional 2025 Notes issued will be treated

23

as a single class for all purposes under this Supplemental Indenture.  With respect to any Additional 2025 Notes, the Company will set forth in a Board Resolution and an Officer’s Certificate, a copy of each which will be delivered to the Trustee, the following information:

(a)                                 the aggregate principal amount of such Additional 2025 Notes to be authenticated and delivered pursuant to this Supplemental Indenture; and

Section 5.01.  Payment of Principal, Premium and Interest.  The Company or any Guarantor, for the benefit of the 2025 Notes, will duly and punctually pay in U.S. Dollars the principal of, premium, if any, and interest, if any, on the 2025 Notes in accordance with the terms of the 2025 Notes and this Supplemental Indenture. An installment of principal of, premium or interest on such 2025 Notes shall be considered paid on the date it is due if the Trustee or a Paying Agent for such 2025 Notes (other than the Company or an Affiliate of the Company) holds on that date immediately available funds designated for and sufficient to pay such installment.

Section 5.03.  Limitation on Sale and Leaseback Transactions.  The Company will not, and will not permit any of its Restricted Subsidiaries to, enter into any sale and leaseback transaction; provided that the Company or any Guarantor may enter into a sale and leaseback transaction if (i) the Company or such Guarantor, as applicable, could have incurred a Lien to secure such Indebtedness in an amount equal to the Attributable Indebtedness relating to such sale and leaseback transaction pursuant to the provisions of Section 5.02 hereof and (ii) the gross cash proceeds of such sale and leaseback transaction are at least equal to the fair market value (as determined in good faith by the Board of Directors of the Company and set forth in an Officers’ Certificate delivered to the Trustee) of the property that is the subject of such sale and leaseback transaction.

To the extent that the provisions of any securities laws or regulations conflict with this Section 5.04, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 5.04 by virtue of such conflict.

(b)           On the Change of Control Payment Date, the Company shall, to the extent lawful, (i) accept for payment all 2025 Notes or portions thereof properly tendered pursuant to the Change of Control Offer, (ii) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all 2025 Notes or portions thereof properly tendered and (iii) deliver or cause to be delivered to the Trustee (by book entry) the 2025 Notes properly accepted together with an Officers’ Certificate stating the aggregate principal amount of 2025 Notes or portions thereof being purchased by the Company. The Paying Agent shall promptly mail to each Holder of 2025 Notes properly tendered the Change of Control Payment for such 2025 Notes, and the Trustee shall promptly cause to be transferred by book entry to each Holder an interest in the 2025 Notes equal in principal amount to any unpurchased portion of the 2025 Notes surrendered by such Holder, if any; provided, that each such 2025 Note shall be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. The Company shall publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

The Company will not be required to make a Change of Control Offer upon a Change of Control Triggering Event if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 5.04 and all other provisions of this Supplemental Indenture applicable to a Change of Control Offer made by the Company and purchases all 2025 Notes properly tendered and not withdrawn under such Change of Control Offer.

The form of such joinder to this Supplemental Indenture is attached hereto as Exhibit B.

Interest will be computed on the basis of a 360-day year of twelve 30-day months.
