(iii) failure by the Company for 90 days after notice to the Company by the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then Outstanding to perform or observe any of the other covenants or agreements in this Indenture (other than defaults specified in clauses (i) or (ii) above);

(iv) any of the Company’s Indebtedness in the aggregate outstanding principal amount of $250 million or more either:

(A) becomes due and payable prior to the due date for payment of such Indebtedness by reason of acceleration of such Indebtedness following a default by the Company; or

16

(B) is not repaid at, and remains unpaid after, maturity as extended by any applicable period of grace or any guarantee given by us in respect of Indebtedness of any other Person in the aggregate outstanding principal amount of $250 million or more is not honored when, and remains dishonored after, becoming due;

(v) the Company pursuant to or within the meaning of any Bankruptcy Law (A) commences a voluntary case, (B) consents to the entry of an order for relief against it in an involuntary case, (C) consents to the appointment of a custodian of it or for all or substantially all of its property or (D) makes a general assignment for the benefit of its creditors; or

(vi) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that (A) is for relief against the Company in an involuntary case, (B) appoints a custodian of the Company for all or substantially all of the Company’s properties, or (C) orders the liquidation of the Company, and, in any of the above cases, the order or decree remains unstayed and in effect for 90 days.

(b) Acceleration of Maturity. In the case of an Event of Default specified in clause (v) or (vi) of Section 1.07(a), all outstanding Notes will become due and payable immediately without further action or notice. If any other 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 immediately by notice in writing to the Company (and to the Trustee if written notice is given by such Holders). Upon any such declaration, the Notes shall become due and payable immediately.

The Holders of a majority in aggregate principal amount of the then outstanding Notes by written notice to the Trustee may, on behalf of all of the Holders, rescind an acceleration and its consequences with respect to such Notes, if the rescission would not conflict with any judgment or decree and if all existing Events of Default with respect to such Notes (except nonpayment of principal, interest or premium that has become due solely because of the acceleration) have been cured or waived.

Section 1.08. Book-Entry Provisions for Global Notes. (a) Each Global Note initially shall (i) be registered in the name of the Depositary for such Global Note or the nominee of such Depositary, in each case for credit to the account of an Agent Member, and (ii) be delivered to the Trustee as custodian for such Depositary. None of the Company, 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 of a Global Note, or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

(b) Members of, or participants in, the Depositary (“ Agent Members ”) shall have no rights under this Indenture with respect to any Global Note held on their behalf by the Depositary, or its custodian, or under such Global Notes. The Depositary may be treated by the Company, any other obligor upon the Notes, the Trustee and any agent of

17

any of them as the absolute owner of the Global Notes for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, any other obligor upon the Notes, the Trustee or any agent of any of them from giving effect to any written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a beneficial owner of any Note. The Holder of a Global Note may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action that a Holder is entitled to take under this Indenture or the Notes.

(c) Transfers of a Global Note shall be limited to transfers of such Global Note in whole, but, subject to the immediately succeeding sentence, not in part, to the Depositary, its successors or their respective nominees. Interests of beneficial owners in a Global Note may not be transferred or exchanged for physical Notes unless (i) the Company has consented thereto in writing, or such transfer or exchange is made pursuant to the next sentence, and (ii) such transfer or exchange is in accordance with the applicable rules and procedures of the Depositary. Subject to the limitation on issuance of physical Notes, physical Notes shall be transferred to all beneficial owners in exchange for their beneficial interests in the relevant Global Note, if (i) the Depositary notifies the Company at any time that it is unwilling or unable to continue as Depositary for the Global Notes and a successor depositary is not appointed within 120 days; (ii) the Depositary ceases to be registered as a “Clearing Agency” under the Exchange Act and a successor depositary is not appointed within 120 days; or (iii) the Company, at its option, notifies the Trustee that it elects to cause the issuance of physical Notes.

(d) The transfer and exchange of a Global Note or beneficial interests therein shall be effected through the Depositary, in accordance with this Indenture (including applicable restrictions on transfer set forth in Section 1.09) and the Applicable Procedures therefor of the Depositary. Any beneficial interest in one of the Global Notes that is transferred to a Person who takes delivery in the form of an interest in a different Global Note will, upon transfer, cease to be an interest in such Global Note and become an interest in the other Global Note and, accordingly, will thereafter be subject to all transfer restrictions, if any, and other procedures applicable to beneficial interests in such other Global Note for as long as it remains such an interest. A transferor of a beneficial interest in a Global Note shall deliver to the Registrar a written order given in accordance with the Depositary’s Applicable Procedures containing information regarding the participant account of the Depositary to be credited with a beneficial interest in the relevant Global Note. The Registrar shall, in accordance with such instructions, instruct the Depositary to credit to the account of the Person specified in such instructions a beneficial interest in such Global Note and to debit the account of the Person making the transfer the beneficial interest in the Global Note being transferred.

Section 1.09. Satisfaction and Discharge of Indenture . This Section 1.09 shall replace Section 9.01(a) of the Base Indenture with respect to the Notes only.

18

(a) either (i) all the Notes that have been authenticated and delivered have been cancelled or delivered to the Trustee for cancellation (other than any Notes which shall have been destroyed, lost or stolen and which shall have been replaced or paid as provided in Section 2.09 of the Base Indenture); or (ii) all the Notes issued that have not been cancelled or delivered to the Trustee for cancellation shall have become due and payable, or are by their terms to become due and payable at their final maturity within one year, or are to be called for redemption within one year, under irrevocable arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the Company’s name, and at the Company’s expense and the Company shall have irrevocably deposited or caused to be deposited with the Trustee sufficient funds to pay and discharge the entire indebtedness on the Notes to pay principal, interest, if any, and any premium, which for purposes of this provision shall be calculated without applying any “present value discount” and using a Treasury Rate of no less than zero.

Section 1.10. Successors . Upon any consolidation or merger, or any sale, transfer, lease, conveyance or other disposition of the assets of the Company substantially as an entirety in a transaction that is subject to, and that complies with the provisions of, Article 8 of the Base Indenture, the successor Person formed by such consolidation or into or with which the Company is merged or to which such sale, lease, transfer, conveyance or other disposition is made shall succeed to, and be substituted for (so that from and after the date of such consolidation, merger, sale, lease, transfer, conveyance or other disposition, the provisions of this Indenture referring to the “Company” shall refer instead to the successor Person and not to the Company), and may exercise every right and power of the Company under this Indenture with the same effect as if such successor Person had been named as the Company herein; provided, however, that the predecessor Company shall not be relieved from the obligation to pay the principal of and interest on the Notes except in the case of a sale of all of the Company’s assets in a transaction that is subject to, and that complies with the provisions of, this Section 1.10.

16

(G) that Holders whose Notes are being purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $2,000 in principal amount or an integral multiple of $1,000 in excess thereof.

The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 1.06(d), the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 1.06(d) by virtue of such compliance.

(iii) failure by the Company for 90 days after notice to the Company by the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes of such series then Outstanding to perform or observe any of the other covenants or agreements in this Indenture applicable to such series (other than defaults specified in clauses (i) or (ii) above);

(iv) any of the Company’s Indebtedness in the aggregate outstanding principal amount of $250 million or more either:

(A) becomes due and payable prior to the due date for payment of such Indebtedness by reason of acceleration of such Indebtedness following a default by the Company; or

(B) is not repaid at, and remains unpaid after, maturity as extended by any applicable period of grace or any guarantee given by us in respect of Indebtedness of any other Person in the aggregate outstanding principal amount of $250 million or more is not honored when, and remains dishonored after, becoming due;

(v) the Company pursuant to or within the meaning of any Bankruptcy Law (A) commences a voluntary case, (B) consents to the entry of an order for relief against it in an involuntary case, (C) consents to the appointment of a custodian of it or for all or substantially all of its property or (D) makes a general assignment for the benefit of its creditors; or

(b) Acceleration of Maturity. In the case of an Event of Default specified in clause (v) or (vi) of Section 1.07(a), all outstanding Notes will become due and payable immediately without further action or notice. If any other 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 of a particular series may declare all the Notes of such series to be due and payable immediately by notice in writing to the Company (and to the Trustee if written notice is given by such Holders). Upon any such declaration, the Notes of such series shall become due and payable immediately.

The Holders of a majority in aggregate principal amount of the then outstanding Notes of a particular series by written notice to the Trustee may, on behalf of all of the Holders of such series, rescind an acceleration and its consequences with respect to such series of Notes, if the rescission would not conflict with any judgment or decree and if all existing Events of Default with respect to such series of Notes (except nonpayment of principal, interest or premium that has become due solely because of the acceleration) have been cured or waived.

Section 1.08. Book-Entry Provisions for Global Notes. (a) Each Global Note initially shall (i) be registered in the name of the Depositary for such Global Note or the nominee of such Depositary, in each case for credit to the account of an Agent Member, and (ii) be delivered to the Trustee as custodian for such Depositary. None of the Company, 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 of a Global Note, or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

(b) Members of, or participants in, the Depositary (“ Agent Members ”) shall have no rights under this Indenture with respect to any Global Note held on their behalf by the Depositary, or its custodian, or under such Global Notes. The Depositary may be treated by the Company, any other obligor upon the Notes, the Trustee and any agent of any of them as the absolute owner of the Global Notes for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, any other obligor upon the Notes, the Trustee or any agent of any of them from giving effect to any written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a beneficial owner of any Note. The Holder of a Global Note may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action that a Holder is entitled to take under this Indenture or the Notes.

(c) Transfers of a Global Note shall be limited to transfers of such Global Note in whole, but, subject to the immediately succeeding sentence, not in part, to the Depositary, its successors or their respective nominees. Interests of beneficial owners in a Global Note may not be transferred or exchanged for physical Notes unless (i) the Company has consented thereto in writing, or such transfer or exchange is made pursuant to the next sentence, and (ii) such transfer or exchange is in accordance with the applicable rules and procedures of the Depositary. Subject to the limitation on issuance

19

of physical Notes, physical Notes shall be transferred to all beneficial owners in exchange for their beneficial interests in the relevant Global Note, if (i) the Depositary notifies the Company at any time that it is unwilling or unable to continue as Depositary for the Global Notes and a successor depositary is not appointed within 120 days; (ii) the Depositary ceases to be registered as a “Clearing Agency” under the Exchange Act and a successor depositary is not appointed within 120 days; or (iii) the Company, at its option, notifies the Trustee that it elects to cause the issuance of physical Notes.

(d) The transfer and exchange of a Global Note or beneficial interests therein shall be effected through the Depositary, in accordance with this Indenture (including applicable restrictions on transfer set forth in Section 1.09) and the Applicable Procedures therefor of the Depositary. Any beneficial interest in one of the Global Notes that is transferred to a Person who takes delivery in the form of an interest in a different Global Note will, upon transfer, cease to be an interest in such Global Note and become an interest in the other Global Note and, accordingly, will thereafter be subject to all transfer restrictions, if any, and other procedures applicable to beneficial interests in such other Global Note for as long as it remains such an interest. A transferor of a beneficial interest in a Global Note shall deliver to the Registrar a written order given in accordance with the Depositary’s Applicable Procedures containing information regarding the participant account of the Depositary to be credited with a beneficial interest in the relevant Global Note. The Registrar shall, in accordance with such instructions, instruct the Depositary to credit to the account of the Person specified in such instructions a beneficial interest in such Global Note and to debit the account of the Person making the transfer the beneficial interest in the Global Note being transferred.

Section 1.09. Satisfaction and Discharge of Indenture. This Section 1.09 shall replace Section 9.01(a) of the Base Indenture with respect to the Notes only.

(a) either (i) all the Notes of such series that have been authenticated and delivered have been cancelled or delivered to the Trustee for cancellation (other than any Notes of such series which shall have been destroyed, lost or stolen and which shall have been replaced or paid as provided in Section 2.09 of the Base Indenture); or (ii) all the Notes of such series issued that have not been cancelled or delivered to the Trustee for cancellation shall have become due and payable, or are by their terms to become due and payable at their final maturity within one year, or are to be called for redemption within one year, under irrevocable arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the Company’s name, and at the Company’s expense and the Company shall have irrevocably deposited or caused to be deposited with the Trustee sufficient funds to pay and discharge the entire indebtedness on the Notes of such series to pay principal, interest, if any, and any premium, which for purposes of this provision shall be calculated without applying any “present value discount” and using a Treasury Rate of no less than zero.

Section 1.10. Successors . Upon any consolidation or merger, or any sale, transfer, lease, conveyance or other disposition of the assets of the Company substantially as an entirety in a transaction that is subject to, and that complies with the provisions of, Article 8 of the Base Indenture, the successor Person formed by such consolidation or

20

into or with which the Company is merged or to which such sale, lease, transfer, conveyance or other disposition is made shall succeed to, and be substituted for (so that from and after the date of such consolidation, merger, sale, lease, transfer, conveyance or other disposition, the provisions of this Indenture referring to the “Company” shall refer instead to the successor Person and not to the Company), and may exercise every right and power of the Company under this Indenture with the same effect as if such successor Person had been named as the Company herein; provided, however, that the predecessor Company shall not be relieved from the obligation to pay the principal of and interest on the Notes except in the case of a sale of all of the Company’s assets in a transaction that is subject to, and that complies with the provisions of, this Section 1.10.
