A Global Note may not be transferred as a whole except by the Depositary to a nominee of the Depositary, by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. All Global Notes of a series will be exchanged by the Company for Definitive Notes if:

(i) the Company delivers to the Trustee notice from the Depositary that (A) it is unwilling or unable to continue to act as Depositary and a successor Depositary is not appointed by the Company within 90 days after the date of such notice from the Depositary or (B) it is no longer a clearing agency registered under the Exchange Act; or

13

(ii) the Company in its sole discretion determines that the Global Notes of such series (in whole but not in part) should be exchanged for Definitive Notes and delivers a written notice to such effect to the Trustee.

Upon the occurrence of either of the preceding events in (i) or (ii) above, Definitive Notes will be issued in such names and in any approved denominations as the Depositary will instruct the Trustee. Global Notes also may be exchanged or replaced, in whole or in part, as provided in Sections 2.08 and 2.11 of the Base Indenture. Every Note authenticated and delivered in exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to this Section 2.02 or 2.08 or 2.11 of the Base Indenture, will be authenticated and delivered in the form of, and will be, a Global Note. A Global Note may not be exchanged for another Note other than as provided in this Section 2.02(a); however, beneficial interests in a Global Note may be transferred and exchanged as provided in Section 2.02(b), (c), (d) or (g) hereof.

(b)Transfer and Exchange of Beneficial Interests in the Global Notes. The transfer and exchange of beneficial interests in the Global Notes will be effected through the Depositary, in accordance with the provisions of this Fourth Supplemental Indenture and the applicable procedures of the Depositary. Transfers of beneficial interests in the Global Notes also will require compliance with either subparagraph (i) or (ii) below, as applicable, as well as one or more of the other following subparagraphs, as applicable:

(i) Transfer of Beneficial Interests in the Same Global Note. Beneficial interests in any Global Note may be transferred to Persons who take delivery thereof in the form of a beneficial interest in a Global Note. No written orders or instructions will be required to be delivered to the Registrar to effect the transfers described in this Section 2.02(b)(i).

(ii) All Other Transfers and Exchanges of Beneficial Interests in Global Notes. In connection with all transfers and exchanges of beneficial interests that are not subject to Section 2.02(b)(i) above, the transferor of such beneficial interest must deliver to the Registrar either:

(A) a written order from a Participant or an Indirect Participant given to the Depositary in accordance with the applicable procedures of the Depositary directing the Depositary to credit or cause to be credited a beneficial interest in another Global Note in an amount equal to the beneficial interest to be transferred or exchanged; or

(B) instructions given in accordance with the applicable procedures of the Depositary containing information regarding the Participant account to be credited with such increase.

Upon satisfaction of all of the requirements for transfer or exchange of beneficial interests in Global Notes contained in this Fourth Supplemental Indenture and the Notes, the Trustee will adjust the principal amount of the relevant Global Note(s) pursuant to Section 2.02(g) hereof.

14

(c)Transfer or Exchange of Beneficial Interests for Definitive Notes. If any Holder of a beneficial interest in a Global Note proposes to exchange such beneficial interest for a Definitive Note or to transfer such beneficial interest to a Person who takes delivery thereof in the form of a Definitive Note, then the transferor of such beneficial interest must deliver to the Registrar a written order from a Participant or an Indirect Participant given to the Depositary in accordance with customary procedures containing information regarding the beneficial interest to be so exchanged or transferred and the recipient of the Definitive Note. Upon satisfaction of the conditions set forth in Section 2.02(b)(ii) hereof, the Trustee will cause the aggregate principal amount of the applicable Global Note to be reduced accordingly pursuant to Section 2.02(g) hereof, and the Company will execute and, upon receipt of an Authentication Order, the Trustee will authenticate and deliver to the Person designated in the instructions a Definitive Note in the appropriate principal amount. Any Definitive Note issued in exchange for a beneficial interest pursuant to this Section 2.02(c) will be registered in such name or names and in such authorized denomination or denominations as the Holder of such beneficial interest requests through instructions to the Registrar from or through the Depositary and the Participant or Indirect Participant. The Trustee will deliver such Definitive Notes to the Persons in whose names such Notes are so registered.

Notwithstanding the foregoing, any exchange or transfer of a beneficial interest in a Global Note for a Definitive Note contemplated by this Section 2.02(c) shall only be permitted if (i) the Company determines at any time that the Notes shall no longer be represented by Global Notes and shall inform such Depositary of such determination or (ii) such exchange or transfer is made upon request by or on behalf of at least 25% of the beneficial owners of the Notes seeking to exercise or enforce their rights under the Securities during the continuance of an Event of Default.

(d)Transfer and Exchange of Definitive Notes for Beneficial Interests. A Holder of a Definitive Note may exchange such Note for a beneficial interest in a Global Note or transfer such Definitive Notes to a Person who takes delivery thereof in the form of a beneficial interest in a Global Note at any time. Upon receipt of a request for such an exchange or transfer, the Trustee will cancel the applicable Definitive Note and increase or cause to be increased the aggregate principal amount of one of the Global Notes.

If any such exchange or transfer from a Definitive Note to a beneficial interest is effected pursuant to the previous paragraph at a time when a Global Note has not yet been issued, the Company will issue and, upon receipt of an Authentication Order, the Trustee will authenticate one or more Global Notes in an aggregate principal amount equal to the principal amount of Definitive Notes so transferred.

A Holder of Definitive Notes may transfer such Notes to a Person who takes delivery thereof in the form of a Definitive Note.

15

(e)Transfer and Exchange of Definitive Notes for Definitive Notes. Upon request by a Holder of Definitive Notes and such Holder’s compliance with the provisions of this Section 2.02(e), the Registrar will register the transfer or exchange of Definitive Notes. Prior to such registration of transfer or exchange, the requesting Holder will present or surrender to the Registrar the Definitive Notes duly endorsed or accompanied by a written instruction of transfer in form satisfactory to the Registrar duly executed by such Holder or by his attorney, duly authorized in writing. In addition, the requesting Holder will provide any additional certifications, documents and information, as applicable, required pursuant to the provisions of this Section 2.02(e).

the outstanding 2050 Notes affected by the amendment or modification, and compliance by the Company with any provision of the Indenture with respect to the 2050 Notes may be waived by written notice to the Trustee by the Holders of a majority of the aggregate principal amount of the outstanding 2050 Notes affected by the waiver. Without the consent of any Holder of the 2050 Notes, the Fourth Supplemental Indenture or the 2050 Notes may be amended or modified in order to, among other things: cure any ambiguity, defect or inconsistency; secure the 2050 Notes, add events of default, covenants or guarantees with respect to the 2050 Notes or make any other change that would provide any additional rights or benefits to the Holders of the 2050 Notes; obtain or maintain the qualification of the Indenture under the Trust Indenture Act; or make any other change that does not adversely affect the interests of any Holder of the 2050 Notes. Subject to certain exceptions, the Holders of at least a majority in principal amount of the outstanding 2050 Notes may on behalf of the Holders of all 2050 Notes waive the Company’s compliance with provisions of the Indenture and waive any past default under the Indenture with respect to the 2050 Notes and its consequences.

12.DEFAULTS AND REMEDIES. An “EVENT OF DEFAULT” occurs if there is:

(i) default in paying interest on the 2050 Notes when it becomes due and the default continues for a period of 30 days or more; or

(ii) default in paying principal, or premium, if any, on the 2050 Notes when due; or

(iii) default in the performance or breach of any other covenant by the Company relating to the 2050 Notes, and the default or breach continues uncured for a period of 90 days or more after the Company receives written notice from the Trustee or the Company and the Trustee receive written notice from the Holders of at least 25% in aggregate principal amount of the outstanding 2050 Notes as provided in the Indenture; or

(iv) certain events of bankruptcy, insolvency or reorganization with respect to the Company pursuant to Section 6.01 of the Fourth Supplemental Indenture; or

(v) failure to make the required payment in connection with a Change of Control Triggering Event when due and payable in accordance with the terms of the Indenture; or

(vi) (a) a failure to make any payment at maturity, including any applicable grace period, of any of the Company’s Indebtedness (other than Indebtedness the Company owes to any of its Subsidiaries) in an amount in excess of $100 million and continuance of this failure to pay or (b) a default on any of the Company’s Indebtedness (other than Indebtedness the Company owes to any of its Subsidiaries), which default results in the acceleration of the maturity such Indebtedness in an amount in excess of $100 million without such Indebtedness

B-6

having been discharged or the acceleration having been cured, waived, rescinded or annulled, in the case of clause (a) or (b) above, for a period of 30 days after written notice thereof to the Company by the Trustee or to the Company and the Trustee by the Holders of not less than 25% in aggregate principal amount of the outstanding 2050 Notes as provided in the Indenture; provided, however, that if any failure, default or acceleration referred to in clause (a) or (b) above ceases or is cured, waived, rescinded or annulled, then the event of default will be deemed cured.

If any Event of Default occurs and is continuing, the Trustee or the Holders of not less than 25% in principal amount of the then outstanding 2050 Notes may, by notice in writing to the Company (and to the Trustee if given by the Holders), declare all the 2050 Notes to be due and payable immediately the principal of, and accrued and unpaid interest, if any, on all of the 2050 Notes. Notwithstanding the foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency with respect to the Company, the principal amount (or such specified amount) of and accrued and unpaid interest, if any, on all outstanding 2050 Notes will become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders of 2050 Notes. Holders may not enforce the Indenture or the 2050 Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding 2050 Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the 2050 Notes notice of any continuing Default or Event of Default if it, in good faith, determines that withholding notice is in their interest, except a Default or Event of Default relating to the payment of principal or interest. The Holders of a majority in aggregate principal amount of the 2050 Notes then outstanding by notice to the Trustee may on behalf of the Holders of all of the 2050 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, or the principal of, the 2050 Notes or in respect if a covenant or a provision that cannot be modified or amended without the consent of all Holders of the 2050 Notes. The Company is required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and the Company is required upon becoming aware of any Default or Event of Default, to deliver to the Trustee a statement specifying such Default or Event of Default.

13.TRUSTEE DEALINGS WITH COMPANY. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not the Trustee.

14.NO RECOURSE AGAINST OTHERS. A director, officer, employee, incorporator or stockholder, of the Company, as such, will not have any liability for any obligations of the Company under the 2050 Notes or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of 2050 Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the 2050 Notes.

Without the consent of any Holder of the 2060 Notes, the Fourth Supplemental Indenture or the 2060 Notes may be amended or modified in order to, among other things: cure any ambiguity, defect or inconsistency; secure the 2060 Notes, add events of default, covenants or guarantees with respect to the 2060 Notes or make any other change that would provide any additional rights or benefits to the Holders of the 2060 Notes; obtain or maintain the qualification of the Indenture under the Trust Indenture Act; or make any other change that does not adversely affect the interests of any Holder of the 2060 Notes. Subject to certain exceptions, the Holders of at least a majority in principal amount of the outstanding 2060 Notes may on behalf of the Holders of all 2060 Notes waive the Company’s compliance with provisions of the Indenture and waive any past default under the Indenture with respect to the 2060 Notes and its consequences.

12.DEFAULTS AND REMEDIES. An “EVENT OF DEFAULT” occurs if there is:

(i) default in paying interest on the 2060 Notes when it becomes due and the default continues for a period of 30 days or more; or

(ii) default in paying principal, or premium, if any, on the 2060 Notes when due; or

(iii) default in the performance or breach of any other covenant by the Company relating to the 2060 Notes, and the default or breach continues uncured for a period of 90 days or more after the Company receives written notice from the Trustee or the Company and the Trustee receive written notice from the Holders of at least 25% in aggregate principal amount of the outstanding 2060 Notes as provided in the Indenture; or

(iv) certain events of bankruptcy, insolvency or reorganization with respect to the Company pursuant to Section 6.01 of the Fourth Supplemental Indenture; or

(v) failure to make the required payment in connection with a Change of Control Triggering Event when due and payable in accordance with the terms of the Indenture; or

(vi) (a) a failure to make any payment at maturity, including any applicable grace period, of any of the Company’s Indebtedness (other than Indebtedness the Company owes to any of its Subsidiaries) in an amount in excess of $100 million and continuance of this failure to pay or (b) a default on any of the Company’s Indebtedness (other than Indebtedness the Company owes to any of its Subsidiaries), which default results in the acceleration of the maturity such Indebtedness in an amount in excess of $100 million without such Indebtedness having been discharged or the acceleration having been cured, waived, rescinded or annulled, in the case of clause (a) or (b) above, for a period of 30 days after written notice thereof to the Company by the Trustee or to the Company and the

C-6

Trustee by the Holders of not less than 25% in aggregate principal amount of the outstanding 2060 Notes as provided in the Indenture; provided, however, that if any failure, default or acceleration referred to in clause (a) or (b) above ceases or is cured, waived, rescinded or annulled, then the event of default will be deemed cured.

If any Event of Default occurs and is continuing, the Trustee or the Holders of not less than 25% in principal amount of the then outstanding 2060 Notes may, by notice in writing to the Company (and to the Trustee if given by the Holders), declare all the 2060 Notes to be due and payable immediately the principal of, and accrued and unpaid interest, if any, on all of the 2060 Notes. Notwithstanding the foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency with respect to the Company, the principal amount (or such specified amount) of and accrued and unpaid interest, if any, on all outstanding 2060 Notes will become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders of 2060 Notes. Holders may not enforce the Indenture or the 2060 Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding 2060 Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the 2060 Notes notice of any continuing Default or Event of Default if it, in good faith, determines that withholding notice is in their interest, except a Default or Event of Default relating to the payment of principal or interest. The Holders of a majority in aggregate principal amount of the 2060 Notes then outstanding by notice to the Trustee may on behalf of the Holders of all of the 2060 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, or the principal of, the 2060 Notes or in respect if a covenant or a provision that cannot be modified or amended without the consent of all Holders of the 2060 Notes. The Company is required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and the Company is required upon becoming aware of any Default or Event of Default, to deliver to the Trustee a statement specifying such Default or Event of Default.

13.TRUSTEE DEALINGS WITH COMPANY. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not the Trustee.

14.NO RECOURSE AGAINST OTHERS. A director, officer, employee, incorporator or stockholder, of the Company, as such, will not have any liability for any obligations of the Company under the 2060 Notes or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of 2060 Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the 2060 Notes.

15.AUTHENTICATION. This Note will not be valid until authenticated by the manual, facsimile or electronic signature of the Trustee or an authenticating agent.
