11

The Securities may be issued from time to time in one or more series. With respect to the Securities of any particular series, there shall be established in, or pursuant to the authority granted in, a resolution of the Board of Directors, and set forth in an Officer’s Certificate, or established in one or more indentures supplemental hereto prior to the issuance of Securities of a series:

14

All Securities of any one series shall be substantially identical except as to denomination and except as may otherwise be provided in, or pursuant to the authority granted in, such resolution of the Board of Directors or in any such indenture supplemental hereto.

Anything herein to the contrary notwithstanding, the Trustee shall be under no obligation to authenticate and deliver Securities of any series the terms of which, established as contemplated by this Section 3.1, would affect the rights, duties, obligations, liabilities or immunities of the Trustee under this Indenture.

Section 3.2 Form, Denominations and Currencies.

In the absence of any specification pursuant to Section 3.1 with respect to the Securities of any series, the Securities of such series shall be issuable as a Global Security in fully registered form in the name of the Holders thereof, without coupons, in denominations of $2,000 and integral multiples of $1,000.

Section 3.3 Authentication, Dating and Delivery of Securities.

At any time and from time to time after the original execution and delivery of this Indenture, the Company may deliver Securities of any series, executed by the Company, to the Trustee for authentication. Except as otherwise provided in this Article III, the Trustee shall thereupon authenticate and make available for delivery, or cause to be authenticated and delivered, said Securities to or upon a Company Order, without any further action by the Company; provided, however, that the Trustee shall authenticate and make available for delivery Securities of such series for original issue from time to time in the aggregate principal amount established for such series pursuant to such procedures, acceptable to the Trustee and to such recipients, as may be specified from time to time by a Company Order. The maturity dates, original issue dates, interest rates and any other terms of the Securities of such series shall be determined by or pursuant to such Company Order and procedures. If provided for in such procedures, such Company Order may authorize authentication and delivery pursuant to oral instructions from the Company or its duly authorized agent, which instructions shall be promptly confirmed in writing.

In authenticating such Securities and accepting the responsibilities under this Indenture in relation to such Securities, the Trustee shall be entitled to receive, prior to the initial authentication of such Securities, and (subject to Section 7.1) shall be fully protected in relying upon:

15

Notwithstanding the provisions of Section 3.1 and of the immediately preceding paragraph, with respect to Securities of a series subject to a Periodic Offering, the Trustee shall be entitled to receive the Officer’s Certificate otherwise required pursuant to Section 3.3(c) and the Opinion of Counsel required by this Section 3.3(d) only once at or prior to the time of the first authentication and delivery of such Securities (provided that such Opinion of Counsel addresses the authentication and delivery of all such Securities) and that, in lieu of the opinions described in Section 3.3(d)(i) and (iii), Counsel may opine that:

With respect to Securities of a series subject to a Periodic Offering, the Trustee may conclusively rely, as to the authorization by the Company of any of such Securities, the forms and terms thereof, the validity thereof and the compliance of the authentication and delivery thereof with the terms and conditions of this Indenture, upon the Opinion of Counsel or Opinions of Counsel, the Officer’s Certificate and the certificates and other documents delivered pursuant to this Section 3.3 at or prior

16

to the time of the first authentication and delivery of Securities of such series until any of such opinions, certificates or other documents have been superseded or revoked or expire by their terms; provided, however, that any request by the Company to the Trustee to authenticate and deliver Securities of such series shall constitute a representation and warranty by the Company that as of the date of such request the statements made in the most recent Officer’s Certificate delivered pursuant to Section 3.3(c) are true and correct as if made on and as of the date thereof.

Any Global Security, shall, unless otherwise provided therein, be delivered to a Depositary designated pursuant to Section 3.1. Each Depositary designated pursuant to Section 3.1 for a Global Security must at the time of its designation and at all times while it serves as such Depositary be a clearing agency registered under the Exchange Act and any other applicable statue or regulation.

The Trustee shall have the right to decline to authenticate and make available for delivery any Securities under this Section 3.3 if the Trustee, being advised by counsel to the Trustee and the Company, determines that such action would expose the Trustee to personal liability.

Each Security shall be dated the date of its authentication, except as otherwise provided pursuant to Section 3.1 with respect to the series of which such Security is a part and except that any substitute Security under Section 3.7 shall be dated so that neither gain nor loss in interest shall result from any mutilation, destruction, loss or theft of the relevant Predecessor Security.

Section 3.4 Execution of Securities.

The Securities shall be signed in the name of and on behalf of the Company by any signatory so designated as authorized to sign on behalf of the Company (the “Company Authorized Signatory”). Such signature may be the manual, facsimile or electronic signature of such Company Authorized Signatory, provided that any electronic signature is a true representation of the Company Authorized Signatory’s actual signature. Typographical and other minor errors or defects in any such signature shall not affect the validity or enforceability of any Security that has been duly authenticated and delivered by the Trustee.

In case any Company Authorized Signatory who shall have signed any of the Securities shall cease to be a Company Authorized Signatory before the Security so signed shall be authenticated and delivered by or on behalf of the Trustee or disposed of by the Company, such Securities nevertheless may be authenticated and delivered or disposed of as though the Company Authorized Signatory who signed such Securities had not ceased to be a Company Authorized Signatory; and any Security may be signed on behalf of the Company by a Company Authorized Signatory as, at the actual date of the original execution of such Security, shall be a Company Authorized Signatory, although at the date of the original execution and delivery of this Indenture, or at the date of such Security, was not a Company Authorized Signatory.

Section 3.5 Certificate of Authentication.

No Security shall be entitled to the benefits of this Indenture or be valid or obligatory for any purpose, unless there appears on such Security a certificate of authentication substantially in the form hereinbefore recited, executed by or on behalf of the Trustee by manual, facsimile or electronic signature, provided that any electronic signature is a true representation of the signer’s actual signature. Such certificate by or on behalf of the Trustee upon any Security executed by the Company shall be conclusive evidence that the Security so authenticated has been duly authenticated and delivered hereunder and that the Holder is entitled to the benefits of this Indenture.

Section 3.6 Registration, Registration of Transfer and Exchange.

Subject to the conditions set forth below (and subject, with respect to Global Securities, to Section 2.3), Securities of any series may be exchanged for a like aggregate principal amount of Securities

17

of the same series and having the same terms but in other authorized denominations. Securities to be exchanged shall be surrendered at the offices or agencies to be maintained for such purposes as provided in Section 4.2, and the Company shall execute and the Trustee shall authenticate and make available for delivery in exchange therefor the Security or Securities which the Holder making the exchange shall be entitled to receive.

The Company shall keep or cause to be kept, at one of said offices or agencies maintained pursuant to Section 4.2, a register for each series of Securities issued hereunder (hereinafter collectively referred to as the “Securities Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall, subject to the provisions of Section 2.3, provide for the registration of Securities of such series and shall register the transfer of Securities of such series as in this Article III provided. The Securities Register shall be in written form or in any other form capable of being converted into written form within a reasonable time. The Trustee is hereby appointed as the initial “Securities Registrar” for the purpose of registering Securities and registering transfers of Securities as herein provided. Subject to the provisions of Section 2.3, upon surrender for registration of transfer of any Security of any series at any such office or agency, the Company shall execute and the Trustee shall authenticate and make available for delivery in the name of transferee or transferees a new Security or Securities of the same series for an equal aggregate principal amount.

The Company shall have the right to remove and replace from time to time the Security Registrar for any series of Securities and the Securities Registrar shall have the right to resign from time to time; provided that no such removal, replacement or resignation shall be effective until a successor Security Registrar with respect to such series of Securities shall have been appointed by the Company and shall have accepted such appointment by the Company. If the Company fails to appoint a successor Securities Registrar within 30 days after the Securities Registrar resigns, the Securities Registrar shall be entitled to appoint a successor and the Company’s consent shall not be unreasonably withheld. In the event that the Trustee shall not be or shall cease to be Security Registrar with respect to a series of Securities, it shall have the right to examine the Security Register for such series at all reasonable times. There shall be only one Security Register for each series of Securities.

All Securities presented for registration of transfer or for exchange, redemption or payment shall (if so required by the Company or the Securities Registrar) be duly endorsed by, or be accompanied by a written instrument or instruments of transfer in form satisfactory to the Company and the Securities Registrar duly executed by, the Holder thereof or his attorney duly authorized in writing.

Each Security issued upon registration of transfer or exchange of Securities pursuant to this Section 3.6 shall be the valid obligation of the Company, evidencing the same indebtedness and entitled to the same benefits under this Indenture as the Security or Securities surrendered upon registration of such transfer or exchange.

No service charge shall be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 3.10, Section 10.6 or Section 14.3 not involving any transfer.

The Company shall not be required (a) to issue, exchange or register the transfer of any Securities of any series during a period beginning at the opening of business 15 days before the day of the mailing of a notice of redemption of Securities of such series and ending at the close of business on the day of such mailing, or (b) to exchange or register the transfer of any Securities selected, called or being called for redemption except, in the case of any Security to be redeemed in part, the portion thereof not to be redeemed.

Section 3.7 Mutilated, Destroyed, Lost and Stolen Securities.

In case any temporary or definitive Security shall become mutilated (whether by defacement or otherwise) or be destroyed, lost or stolen, and in the absence of notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall, except as otherwise provided in this Section 3.7, execute, and upon a Company Request, the Trustee shall authenticate and make available for delivery, a new Security of the same series, tenor and principal amount, bearing a number, letter or other distinguishing symbol not contemporaneously outstanding, in exchange and substitution for the mutilated Security, or in lieu of and in substitution for the Security so destroyed, lost or stolen. In every case the applicant for a substituted Security shall furnish to the Company and to the Trustee and any agent of the Company or the Trustee such security or indemnity as may be required by them to save each of them harmless, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company and the Trustee and any agent of the Company or the Trustee evidence to their satisfaction of the destruction, loss or theft of such Security and of the ownership thereof.

Upon the issuance of any substitute Security under this Section 3.7, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith.

In case any Security which has matured or is about to mature or has been called for redemption in full shall become mutilated or be destroyed, lost or stolen, the Company may, instead of issuing a substitute Security, pay or authorize the payment of the same (without surrender thereof except in the case of a mutilated Security). In every case, the applicant for such payment shall furnish to the Company and to the Trustee and any agent of the Company or the Trustee such security or indemnity as any of them may require to save each of them harmless, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company and the Trustee and any agent of the Company or the Trustee evidence to their satisfaction of the destruction, loss or theft of such Security and of the ownership thereof.

Every substitute Security of any series issued pursuant to the provisions of this Section 3.7 by virtue of the fact that any such Security is destroyed, lost or stolen shall constitute an additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone and shall be entitled to all the benefits of (but shall be subject to all the limitations of rights set forth in) this Indenture equally and proportionately with any and all other Securities of such series duly authenticated and delivered hereunder. All Securities shall be held and owned upon the express condition that, to the extent permitted by law, the foregoing provisions of this Section 3.7 are exclusive with respect to the replacement or payment of mutilated (whether by defacement or otherwise) or destroyed, lost or stolen Securities and shall preclude any and all other rights or remedies notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement or payment of negotiable instruments or other securities without their surrender.

Section 3.8 Payment of Interest and Certain Additional Amounts; Interest Rights and Certain Additional Amounts Preserved.

The Holder of any Securities at the close of business on the Regular Record Date with respect to any Interest Payment Date shall be entitled to receive the interest, if any, and any Additional Amounts payable on such Interest Payment Date notwithstanding the cancellation of such Securities upon

19

any registration of transfer or exchange subsequent to the Regular Record Date and prior to such Interest Payment Date, and, if provided for in the Board Resolution or supplemental indenture pursuant to Section 3.1, in the case of a Security issued between a Regular Record Date and the initial Interest Payment Date relating to such Regular Record Date, interest for the period beginning on the date of issue and ending on such initial Interest Payment Date shall be paid to the Person to whom such Security shall have been originally issued. Except as otherwise specified as contemplated by Section 3.1, for Securities of a particular series the term “Regular Record Date” as used in this Section 3.8 with respect to any Interest Payment Date shall mean the close of business on the last day of the calendar month preceding such Interest Payment Date if such Interest Payment Date is the fifteenth day of a calendar month and shall mean the close of business on the fifteenth day of the calendar month preceding such Interest Payment Date if such Interest Payment Date is the first day of a calendar month, whether or not such day shall be a Business Day. At the option of the Company, payment of interest on any Security may be made by check mailed to the address of the Person entitled thereto (which shall be the Depository in the case of Global Securities) as such address shall appear in the Securities Register.

If and to the extent the Company shall default in the payment of the interest due or any Additional Amounts on such Interest Payment Date in respect of any Securities, such defaulted interest shall be paid by the Company at its election in each case, as provided in Section 3.8(a) or (b):

Subject to the foregoing provisions of this Section 3.8, each Security delivered under this Indenture upon registration of transfer of, or in exchange for, or in lieu of, any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security.

Section 3.9 Cancellation of Securities; Destruction Thereof.

All Securities surrendered for payment, redemption, registration of transfer or exchange, or for credit against any payment in respect of a sinking or analogous fund, shall, if surrendered to the Company or any Paying Agent or any Securities Registrar, be delivered to the Trustee for cancellation or, if surrendered to the Trustee, shall be cancelled by it, and no Securities shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Indenture. The Company may at any time deliver to the Trustee for Securities of a series for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and all Securities so delivered shall be promptly cancelled by such Trustee. Notwithstanding any other provision of this Indenture to the contrary, in the case of a series, all the Securities of which are not to be originally issued at one time, a Security of such series shall not be deemed to have been Outstanding at any time hereunder if and to the extent that, subsequent to the authentication and delivery thereof, such Security is delivered to the Trustee for such Security for cancellation by the Company or any agent thereof upon the failure of the original purchaser thereof to make payment therefore against delivery thereof, and any Security so delivered to such

20

Trustee shall be promptly cancelled by it. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section 3.9, except as expressly permitted by this Indenture. Global Securities shall not be disposed of until exchanged in full for definitive Securities or until payment thereof is made in full. The Trustee shall, unless instructed to deliver the Securities to the Company in a Company Order, destroy such cancelled Securities and, if requested by the Company in writing, deliver certification of their destruction to the Company. If the Company shall acquire any of the Securities, such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented by such Securities unless and until the same are delivered to the Trustee for cancellation.

Section 3.10 Temporary Securities.

Pending the preparation by the Company of definitive Securities of any series, the Company may execute and the Trustee shall authenticate and make available for delivery in the manner provided in Section 3.3, temporary Securities for such series (printed, lithographed, typewritten or otherwise reproduced, in each case in form satisfactory to the Trustee). Temporary Securities of any series shall be issuable in any authorized denomination, and substantially in the form of the definitive Securities of such series in lieu of which they are issued but with such omissions, insertions and variations as may be appropriate for temporary securities, all as may be determined by the Company. Temporary Securities may contain such reference to any provisions of this Indenture as may be appropriate. Every temporary Security shall be executed by the Company and be authenticated by the Trustee upon the same conditions and in substantially the same manner, and with like effect, as the definitive Securities. Without unreasonable delay the Company shall execute and shall furnish definitive Securities of such series and thereupon temporary Securities of such series may be surrendered in exchange therefor without charge at the Corporate Trust Office of the Trustee, and the Trustee shall authenticate and make available for delivery in exchange for such temporary Securities an equal aggregate principal amount of definitive Securities of the same series. Such exchange shall be made by the Company at its own expense and without any charge therefore to the Holders. Until so exchanged, the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of such series authenticated and delivered hereunder.

Section 3.11 Computation of Interest.

Except as otherwise specified as contemplated by Section 3.1 for Securities of any series, interest on the Securities of each series shall be computed on the basis of a 360-day year of twelve 30-day months.

Section 3.12 CUSIP Numbers.

The Company in issuing the Securities may use “CUSIP,” Common Code” or “ISIN” numbers (if then generally in use), and, if so, such numbers shall be used in notices of redemption as a convenience to Holders as set-forth in Section 14.2.

ARTICLE IV

COVENANTS OF THE COMPANY

The Company covenants and agrees for the benefit of each series of Securities (except to the extent that any series of Securities is excluded from the benefits of any of such covenants pursuant to Sections 3.1(a) and 3.1(cc)) that on and after the date of original execution of this Indenture and so long as any of the Securities of such series remain Outstanding:

21

Section 4.1 Payment of Securities.

The Company will duly and punctually pay or cause to be paid in the currency or currency unit in which the Securities of such series are payable, the principal of, any premium and interest on, and any Additional Amounts with respect to the Securities of such series at the place or places, at the respective times and in the manner provided in such Securities and in this Indenture.

Section 4.2 Offices or Agency.

So long as any of the Securities remain Outstanding, the Company will maintain in the Borough of Manhattan, The City of New York, New York, and in each Place of Payment for the Securities of a series, an office or agency where Securities of that series may be presented or surrendered for payment, where Securities of that series may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Company in respect of Securities of that series and this Indenture may be served (which shall initially be the Corporate Trust Office of the Trustee). The Company will give prompt written notice to the Trustee for the Securities of that series of the location, and any change in the location of any such office or agency. If at any time the Company shall fail to maintain such required office or agency in respect of any series of Securities or shall fail to furnish the Trustee with the required information with respect thereto, presentations, surrenders, notices and demands in respect of Securities of that series may be made or served at the Corporate Trust Office of the Trustee; and the Company hereby appoints the Trustee to receive all such presentations, surrenders, notices and demands.

The Company may also from time to time designate one or more other offices or agencies (in or outside The City of New York) where the Securities of one or more series, or any Tranche thereof may be presented or surrendered for any or all of such purposes, and may from time to time rescind such designation; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain for such purposes an office or agency in the Borough of Manhattan, The City of New York and in each Place of Payment for such purpose. The Company will promptly notify the Trustee for the Securities of each series as affected of any such designation or rescission thereof and of any change in the location of any such office or agency.

Unless otherwise specified with respect to any Securities pursuant to Section 3.1, if and so long as the Securities of any series (i) are denominated in a Foreign Currency or (ii) may be payable in a Foreign Currency, or so long as it is required under any other provision of this Indenture, then the Company will maintain with respect to each such series of Securities, or as so required, at least one exchange rate agent.

Section 4.3 Money for Securities Payments to Be Held in Trust.

If the Company shall at any time act as its own Paying Agent with respect to any series of Securities, it shall by 10 a.m. (New York City time), on or before each due date of the principal of, any premium or interest on or Additional Amounts with respect to any of the Securities of such series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum in the currency or currencies, currency unit or units or composite currency or currencies in which the Securities of such series are payable (except as otherwise specified pursuant to Section 3.1 for the Securities of such series) sufficient to pay the principal or any premium, interest or Additional Amounts so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided, and shall promptly notify the Trustee in writing of its action or failure so to act.

Whenever the Company shall have one or more Paying Agents for any series of Securities, it shall, on or prior to each due date of the principal of, any premium or interest on or any Additional Amounts with respect to any Securities of such series, deposit with any Paying Agent a sum (in the currency or currencies, currency unit or units or composite currency or currencies described in the preceding

22

paragraph) sufficient to pay the principal and any premium, interest or Additional Amounts so becoming due, such sum to be held in trust for the benefit of the Persons entitled thereto, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee in writing of its action or failure so to act.

The Company shall cause each Paying Agent for any series of Securities other than the Trustee to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section 4.3, that such Paying Agent shall:

The Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same terms as those upon which such sums were held by the Company or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such sums.

Anything in this Section 4.3 to the contrary notwithstanding, the agreement to hold sums in trust as provided in this Section 4.3 is subject to the provisions of Section 12.3, Section 12.4 and Section 12.5.

Section 4.4 Additional Amounts.

Unless otherwise provided in the Board Resolution or supplemental indenture pursuant to Section 3.1 establishing the terms of a particular series of Securities, the Company will make all payments of principal and premium, if any, interest and any other amounts on, or in respect of, the Securities of any series without withholding or deduction at source for, or on account of, any present or future taxes, fees, duties, assessments or governmental charges of whatever nature imposed or levied by or on behalf of any Relevant Jurisdiction or any political subdivision of any Relevant Jurisdiction or any authority in or of any Relevant Jurisdiction having the power to tax, unless such taxes, fees, duties, assessments or governmental charges are required to be withheld or deducted. If a withholding or deduction at source is required, the Company shall, unless otherwise provided in the Board Resolution or supplemental indenture pursuant to Section 3.1 establishing the terms of a particular series of Securities, subject to certain limitations and exceptions set forth below, pay to the Holder of any such Security such Additional Amounts as may be necessary so that every net payment of principal, premium, if any, interest or any other amount made to such Holder, after such withholding or deduction, shall not be less than the amount provided for in such Security and this Indenture to be then due and payable; provided, however, that the Company shall not be required to make payment of such Additional Amounts:

23

nor shall Additional Amounts be paid with respect to any payment of the principal of, or premium, if any, interest or any other amounts on, any such Security to any Holder who is a fiduciary or partnership or other than the sole beneficial owner of such Security if such payment would be required by the laws of the Relevant Jurisdiction (or any political subdivision or relevant taxing authority thereof or therein) to be included in the income for tax purposes of a beneficiary or partner or settlor with respect to such fiduciary or a member of such partnership or a beneficial owner who would not have been entitled to such Additional Amounts had it been the Holder of the Security.

For the purposes hereof the “Relevant Date” means the date on which the payment of principal of (or premium, if any, on) or interest, if any, on any series of Securities first becomes due or (if any amount of the money payable is improperly withheld or refused) the date on which payment in full of the amount outstanding is made or (if earlier) the date on which notice is duly given to such Holder that upon presentation of the Security in global or definitive form payment will be made provided that payment is in fact made upon such presentation.

For the purposes hereof the “Relevant Jurisdiction” means the United Kingdom or any other jurisdiction in which the Company is resident for tax purposes.

Whenever in this Indenture there is mentioned, in any context, the payment of the principal of or any premium, interest or any other amounts on, or in respect of, any Security of any series or the net proceeds received on the sale or exchange of any Security of any series, such mention shall be deemed to include mention of the payment of Additional Amounts provided by the terms of such series established hereby or pursuant hereto to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof pursuant to such terms, and express mention of the payment of Additional Amounts (if applicable) in any provision hereof shall not be construed as excluding the payment of Additional Amounts in those provisions hereof where such express mention is not made.

Notwithstanding any other provision of this Indenture, any amounts to be paid on the debt securities by or on behalf of the Company, will be paid net of any deduction or withholding imposed or required pursuant to an agreement described in Section 1471(b) of the U.S. Internal Revenue Code of 1986, as amended (the “Code”), or otherwise imposed pursuant to Sections 1471 through 1474 of the

24

Code (or any regulations thereunder or official interpretations thereof) or an intergovernmental agreement between the United States and another jurisdiction facilitating the implementation thereof (or any fiscal or regulatory legislation, rules or practices implementing such an intergovernmental agreement) (any such withholding or deduction, a “FATCA Withholding”). Neither the Company nor any other person will be required to pay any additional amounts in respect of FATCA Withholding.

Each of the Paying Agent and the Trustee, as applicable, shall be entitled to deduct any FATCA Withholding, and shall have no obligation to gross-up any payment hereunder or to pay any additional amount as a result of such FATCA Withholding.

The Company shall notify the Paying Agent and Trustee, as applicable, in the event that any payment (or portion thereof) to be made pursuant to this Indenture is treated as a “withholdable payment” within the meaning of Section 1473(1)(A) of the Code or a “passthru payment” within the meaning of Section 1471(d)(7) of the Code and, to the extent it is able to do so, the extent to which it is so treated.

Section 4.5 Redemption for Tax Purposes.

Unless otherwise provided in the Board Resolution or supplemental indenture pursuant to Section 3.1 establishing the terms of a particular series of a Securities, the Company or any successor Person appointed pursuant to Section 11.3 may redeem the Securities at its option, in whole but not in part, at a Redemption Price equal to 100% of the principal amount, together with accrued and unpaid interest and Additional Amounts, if any, to the date fixed for redemption, if as a result of any change in or amendment to the laws or treaties (or any regulations or rulings promulgated under these laws or treaties) of the Relevant Jurisdiction or any taxing authority in the Relevant Jurisdiction (or any political subdivision) or any change in the application or official interpretation of such laws, regulations or rulings occurring, in the case of a redemption by the Company, on or after the date of issuance of the relevant series of Securities or, in the case of a redemption any successor Person appointed pursuant to Section 11.3, on or after the date on which the successor Person assumes the obligation under the Securities, the Company will be required as of the next Interest Payment Date to pay Additional Amounts with respect to the Securities as provided in Section 4.4 and such requirements cannot be avoided by the use of reasonable measures (such measures not involving any material additional payments or expense by the Company) then available. If the Company elects to redeem the Securities under this provision it will give written notice of such election to the Trustee. If the Company elects to redeem the Securities under this provision it will also mail a notice of redemption at least 30 days but no more than 60 days before the Redemption Date to each Holder of the Securities to be redeemed. Unless the Company defaults in the payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on the Securities or portions thereof called for redemption. Any such redemption will be subject to Article XIV hereof.

Prior to giving the notice of a tax redemption, the Company will deliver to the trustee an Officer’s Certificate stating that the Company is entitled to effect the redemption and setting forth a statement of facts showing that the conditions precedent to the Company’s right to so redeem have occurred.

Section 4.6 Negative Pledge.

Unless otherwise specified with respect to Securities of a particular series pursuant to Section 3.1 (and in which case in respect of such Securities only), so long as any Securities are Outstanding, the Company will not create or permit to subsist any mortgage, charge, pledge, lien, security interest or other encumbrance upon the whole or any part of its undertaking, its assets or revenues present or future to secure any Relevant Indebtedness, or any guarantee of or indemnity in respect of any Relevant Indebtedness unless, at the same time or prior thereto, the Company’s obligations under the Securities of such series and this Indenture (a “Lien”) shall (a) be secured equally and ratably with such Relevant Indebtedness or benefit from a guarantee or indemnity in substantially identical

25

terms thereto, as the case may be, in each case to the satisfaction of the Trustee, or (b) have the benefit of such other Security, guarantee, indemnity or other arrangement as the Trustee in its absolute discretion shall deem to be not materially less beneficial to the Holders of Securities of such series or as shall be approved by the Holder of no less than 75% in aggregate principal amount of securities of any such series.

Section 4.7 Corporate Existence.

Subject to Article XI and Section 4.6, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect its legal existence and rights (charter and statutory) and franchises; provided, however, that the foregoing shall not obligate the Company to preserve any such right or franchise if the Company shall determine that the preservation thereof is no longer desirable in the conduct of its business and that the loss thereof is not disadvantageous in any material respect to any Holder.

Section 4.8 Waiver of Certain Covenants.

The Company may omit in any particular instance to comply with any term, provision or condition set forth in Sections 4.6, 4.7 or 4.8 and any other covenant not set forth herein and specified pursuant to Section 3.1 to be applicable with respect to the Securities of any series if before or after the time for such compliance the Holders of at least a majority (or 75% in case of the covenant to provide security approved by 75% of the Holders pursuant to Section 4.6) in principal amount of the Outstanding Securities of such series (which, in the case of a covenant not set forth herein and specified pursuant to Section 3.1 to be applicable to the Securities of any series, shall include only those series to which such covenant is so specified to be applicable), by Act of such Holders, either shall waive such compliance in such instance or generally shall have waived compliance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee and the Principal Paying Agent for the Securities of such series in respect of any such term, provision or condition shall remain in full force and effect.

Section 4.9 Certificates to Trustee.

For so long as any series of Securities are Outstanding under this Indenture, the Company will, within 120 days after the end of its fiscal year, file with the Trustee an Officer’s Certificate complying with the provisions of the second paragraph of Section 13.6, stating whether or not, to the knowledge of the signers which, shall be the chief executive officer, treasurer or finance director of the Company, the Company has complied with the conditions and covenants on its part contained in this Indenture, and, if the signer, to the best of his or her knowledge, know of any event which is, or after notice or lapse of time or both would become, a default by the Company in the performance, observance or fulfillment of any such condition or covenant, specifying each such default and the nature thereof. For the purpose of this Section 4.9, compliance shall be determined without regard to any grace period or requirement of notice provided pursuant to the terms of this Indenture.

Section 4.10 Calculation of Original Issue Discount.

The Company shall file with the Trustee promptly at the end of each calendar year (i) a written notice specifying the amount of original issue discount (including daily rates and accrual periods) accrued on any Outstanding Original Issue Discount Securities as of the end of such year and (ii) such other specific information relating to such original issue discount as may then be relevant under the Code, as amended from time to time.

ARTICLE V

SECURITYHOLDER LISTS AND REPORTS BY THE COMPANY AND THE TRUSTEE

Section 5.1 Company to Furnish Trustee Information as to Names and Addresses of Securityholders.

The Company covenants and agrees that it will furnish or cause to be furnished to the Trustee a list in such form as the Trustee may reasonably require of the names and addresses of the Holders of the Securities of each series semiannually and not later than June 30 and December 31 in each year, and at such other times as the Trustee may request in writing, as of a date no more than 15 days prior to the date such information is so furnished; provided that, if and so long as the Trustee shall be the Securities Registrar for such series, such list shall not be required to be furnished.

Section 5.2 Preservation and Disclosure of Securityholder Lists.

If the Trustee shall elect not to afford to such applicants access to such information, the Trustee shall, upon the written request of such applicants, mail to each Securityholder of such series or all Securities, as the case may be, whose name and address appear in the information preserved at the time by the Trustee in accordance with the provisions of Section 5.2(a), a copy of the form of

27

proxy or other communication which is specified in such request, with reasonable promptness after a tender to the Trustee of the material to be mailed and of payment, or provision for the payment, of the reasonable and properly incurred expenses of a mailing, unless within five days after such tender, the Trustee shall mail to such applicants and file with the Commission together with a copy of the material to be mailed, a written statement to the effect that, in the opinion of the Trustee, such mailing would be contrary to the best interest of the Holders of Securities of such series or all Securities, as the case may be, or could be in violation of applicable law. Such written statement shall specify the basis of such opinion. If the Commission, after opportunity for a hearing upon the objections specified in the written statement so filed, shall enter an order refusing to sustain any of such objections or if, after the entry of such order sustaining one or more of such objections, the Commission shall find, after notice and opportunity for hearing, that all the objections so sustained have been met, and shall enter an order so declaring, the Trustee shall mail copies of such material to all such Securityholders with reasonable promptness after the entry of such order and the renewal of such tender; otherwise the Trustee shall be relieved of any obligation or duty to such applicants respecting their application.

Section 5.3 Reports by the Company.

The Company covenants:

The delivery of such reports, information and documents to the Trustee pursuant to this Section 5.3 is for informational purposes only and the Trustee’s receipt of such shall not constitute actual or constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officer’s Certificates) other than with respect to Section 7.2.

28

Section 5.4 Reports by the Trustee.

ARTICLE VI

REMEDIES OF THE TRUSTEE AND SECURITYHOLDERS ON EVENT OF DEFAULT

Section 6.1 Event of Default Defined; Acceleration of Maturity; Waiver of Default.

“Event of Default”, with respect to the Securities of any series, wherever used herein, means each one of the following events which shall have occurred and be continuing (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body), unless it is either inapplicable to a particular series or it is specifically deleted or modified in the applicable resolution of the Board of Directors or in the supplemental indenture under which such series of Securities is issued, as the case may be, as contemplated by Section 3.1:

29

If an Event of Default described in Section 6.1(a), (b), (c), (d) or (i) occurs and is continuing with respect to Securities of any series at the time Outstanding, the Trustee or the Holders of not less than 25% in aggregate principal amount of the Securities of such series then Outstanding, by notice in writing to the Company (and to the Trustee if given by Securityholders), may declare the entire principal (or, if the Securities of such series are Original Issue Discount Securities, such portion of the principal as may be specified in the terms of such series) of all Securities of such series and the interest accrued thereon, if any, to be due and payable immediately, and upon any such declaration the same shall become immediately due and payable.

If any Event of Default described in Section 6.1(e), (f), (g) or (h) occurs and is continuing, all unpaid principal of the Securities then Outstanding of that series and the interest accrued thereon, if any, shall ipso facto become and be immediately due and payable without declaration, presentment, demand or notice of any kind by the Trustee or any Holder of Securities of that series.

The foregoing provisions, however, are subject to the condition that if, at any time after a declaration of acceleration with respect to the Securities of any series has been made and before any judgment or decree for the payment of the moneys due shall have been obtained or entered as hereinafter provided, the Company shall pay or shall deposit with the Trustee a sum sufficient to pay all matured installments of interest, if any, and any Additional Amounts with respect to all the Securities of such series (or upon all the Securities, as the case may be) and the principal of (and premium, if any, on) any and all Securities of such series (or of all the Securities, as the case may be) which shall have become due otherwise than by acceleration (with interest upon such principal and premium, if any, and, to the extent that payment of such interest is enforceable under applicable law, on overdue installments of interest or Additional Amounts, at the Overdue Rate applicable to such series to the date of such payment or deposit) and all amounts payable to the Trustee pursuant to the provisions of Section 7.6, and such amount as shall be sufficient to cover reasonable compensation to the Trustee, its agents, attorneys and counsel, and all other expenses and liabilities incurred, and all

30

advances made, by the Trustee except as a result of negligence or bad faith, and if any and all Events of Default under this Indenture, other than the nonpayment of the principal of and accrued interest on and any Additional Amounts with respect to Securities of such series which shall have become due by acceleration, shall have been cured, waived or otherwise remedied as provided herein — then and in every such case the Holders of a majority in aggregate principal amount of the Securities of such series (each series voting as a separate class), or of all the Securities (voting as a single class), as the case may be, then Outstanding, by written notice to the Company and to the Trustee, may waive all defaults with respect to that series (or with respect to all the Securities, as the case may be) and rescind and annul such acceleration and its consequences, but no such waiver or rescission and annulment shall extend to or shall affect any subsequent default or shall impair any right consequent thereon.

For all purposes under this Indenture, if a portion of the principal of any Original Issue Discount Security shall have been accelerated and declared or become due and payable pursuant to the provisions hereof, then, from and after such acceleration, unless such acceleration has been rescinded and annulled, the principal amount of such Original Issue Discount Security shall be deemed, for all purposes hereunder, to be such portion of the principal thereof as shall be due and payable as a result of such acceleration, and payment of such portion of the principal thereof as shall be due and payable as a result of such acceleration, together with interest, if any, thereon and all other amounts owing thereunder, shall constitute payment in full of such Original Issue Discount Security.

Section 6.2 Collection of Indebtedness by Trustee; Trustee May Prove Debt.

The Company covenants that (a) in case default shall be made in the payment of any installment of interest on or any Additional Amounts with respect to any of the Securities of any series when such interest shall have become due and payable, and such default shall have continued for a period of 30 days or (b) in case default shall be made in the payment of all or any part of the principal of or any premium, if any, on any Securities of any series or any Additional Amounts with respect thereto when the same shall have become due and payable, whether upon Stated Maturity of the Securities of such series or upon any redemption or by acceleration or otherwise, then upon demand of the Trustee for such series, the Company will pay to the Trustee for the benefit of the Holder of any such Security the whole amount that then shall have become due and payable on any such Security for the principal, premium, if any, and interest, if any, with interest upon the overdue principal and premium, if any, and, so far as payment of the same is enforceable under applicable law, on overdue installments of interest and Additional Amounts, at the Overdue Rate applicable to any such Security; and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, and any further amounts payable to the Trustee, its agents and counsel pursuant to the provisions of Section 7.6.

In case the Company shall fail forthwith to pay such amounts upon such demand, the Trustee, in its own name and as trustee of an express trust, shall be entitled and empowered to institute any action or proceedings at law or in equity for the collection of the sums so due and unpaid, and may prosecute any such action or proceedings to judgment or final decree, and may enforce any such judgment or final decree against the Company or other obligor upon such Securities and collect in the manner provided by law out of the property of the Company or other obligor upon such Securities, wherever situated, the moneys adjudged or decreed to be payable.

The Trustee shall be entitled and empowered, either in its own name as trustee of an express trust, or as attorney-in-fact for the Holders of any of the Securities, or in both such capacities, to file such proof of debt, amendment of proof of debt, claim, petition or other document as may be necessary or advisable in order to have the claims of the Trustee and of the Holders of Securities allowed in

31

any equity receivership, insolvency, bankruptcy, liquidation, readjustment, reorganization or other similar proceedings, or any judicial proceedings, relative to the Company or any other obligor on the Securities or its creditors or its property. The Trustee is hereby irrevocably appointed (and the successive respective Holders of the Securities, by taking and holding the same, shall be conclusively deemed to have so appointed the Trustee) the true and lawful attorney-in-fact of the respective Holders of the Securities, with authority to make or file in the respective names of the Holders of the Securities any proof of debt, amendment of proof of debt, claim, petition or other document in any such proceedings and to receive payment of any sums becoming distributable on account thereof, and to execute any other papers and documents and do and perform any and all acts and things for and on behalf of such Holders of the Securities as may be necessary or advisable in the opinion of the Trustee in order to have the respective claims of the Holders of the Securities against the Company or any other obligor on the Securities and/or its property allowed in any such proceedings, and to receive payment of or on account of such claims; provided, however, that nothing herein contained shall be deemed to authorize or empower the Trustee to consent to or accept or adopt, on behalf of any Holder of Securities, any plan of reorganization or readjustment of the Company or any other obligor on the Securities or, by other action of any character in any such proceeding, to waive or change in any way any right of any Holder of any Security, even though it may otherwise be entitled so to do under any present or future law, all such power or authorization being hereby expressly denied.

All rights of action and of asserting claims under this Indenture or under any of the Securities may be enforced by the Trustee without the possession of any of the Securities or the production thereof in any trial or other proceedings relative thereto, and any such action or proceedings instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment, subject to the payment of the expenses, disbursements and compensation of the Trustee, each predecessor Trustee and their respective agents and attorneys, shall be for the ratable benefit of the holders of the Securities in respect of which such action was taken.

In any proceedings brought by the Trustee (and also any proceedings involving the interpretation of any provision of this Indenture to which the Trustee shall be a party), the Trustee shall be held to represent all the Holders of the Securities in respect of which such action was taken, and it shall not be necessary to make any Holders of such Securities parties to any such proceedings.

Section 6.3 Application of Proceeds.

Any moneys collected by the Trustee pursuant to this Article VI in respect of any series of the Securities, together with any other sums held by the Trustee (as such) hereunder (other than sums held in trust for the benefit of the Holders of particular Securities), shall be applied in the following order at the date or dates fixed by the Trustee and, in case of the distribution of such moneys on account of principal, or any premium, interest or Additional Amounts, upon presentation (except in respect of Subdivision First below) of the several Securities in respect of which moneys have been collected and stamping (or otherwise noting) thereon the payment, or issuing Securities of such series in reduced principal amounts in exchange for the presented Securities of like series if only partially paid, or upon surrender thereof if fully paid:

32

SECOND: In case the principal of the Securities of such series in respect of which moneys have been collected shall not have become and be then due and payable, to the payment of interest and any Additional Amounts on the Securities of such series in default in the order of the maturity of the installments of such interest, with interest (to the extent that such interest has been collected by the Trustee), so far as it may be enforceable under applicable law, upon the overdue installments of interest and any Additional Amounts at the Overdue Rate applicable to such series, such payments to be made ratably to the Persons entitled thereto, without discrimination or preference;

THIRD: In case the principal of the Securities of such series in respect of which moneys have been collected shall have become and shall be then due and payable, to the payment of the whole amount then owing and unpaid upon all the Securities of such series for principal and premium, if any, and interest, if any, and any Additional Amounts, with interest upon the overdue principal and premium, if any, and (to the extent that such interest has been collected by the Trustee), so far as payment of the same is enforceable under applicable law, upon overdue installments of interest and any Additional Amounts, if any, at the Overdue Rate applicable to such series; and in case such moneys shall be insufficient to pay in full the whole amount so due and unpaid upon the Securities of such series, then to the payment of such principal, premium, if any, and interest, if any, and any Additional Amounts, without preference or priority of principal and premium, if any, over interest or any Additional Amounts, or of interest or any Additional Amounts, if any, over principal and premium, if any, or of any installment of interest over any other installment of interest, or of any Security of such series over any other Security of such series, ratably to the aggregate of such principal, premium, if any, and accrued and unpaid interest, if any; and

FOURTH: To the payment of the remainder, if any, to the Company or as a court of competent jurisdiction may direct in writing.

Section 6.4 Suits for Enforcement.

In case an Event of Default with respect to Securities of any series has occurred, has not been waived and is continuing, the Trustee may in its discretion proceed to protect and enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any of such rights, either at law or in equity or in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any power granted in this Indenture or to enforce any other legal or equitable right vested in the Trustee by this Indenture or by law.

Section 6.5 Restoration of Rights on Abandonment of Proceedings.

In case the Trustee or any Holder shall have proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or abandoned for any reason, or shall have been determined adversely to the Trustee or such Holder, then and in every such case (subject to the binding effect of any determination made in such proceedings) the Company and the Trustee and each of the Holders shall be restored severally and respectively to their former positions and rights hereunder, and (subject as aforesaid) all rights, remedies and powers of the Company, the Trustee and the Holders shall continue as though no such proceedings had been instituted.

Section 6.6 Limitations on Suits by Securityholders.

No Holder of any Security of any series shall have any right by virtue or by availing of any provision of this Indenture to institute an action or proceeding at law or in equity or in bankruptcy or otherwise upon or under or with respect to this Indenture, or for the appointment of a trustee, receiver, liquidator, custodian or other similar official or for any other remedy hereunder, unless such ▇▇▇▇▇▇ previously shall have given to the Trustee written notice of an Event of Default and of the continuance thereof, as hereinbefore provided, and unless also the Holders of not less than 25% in aggregate

33

principal amount of the Securities of such series then Outstanding shall have made written request upon the Trustee to institute such action or proceeding in its own name as Trustee hereunder and shall have offered to the Trustee such sufficient indemnity as it may require against the costs, expenses and liabilities to be incurred therein or thereby and the Trustee for 60 days after its receipt of such notice, request and offer of indemnity shall have failed to institute any such action or proceeding and no direction inconsistent with such written request shall have been given to the Trustee pursuant to Section 6.9; it being understood and intended, and being expressly covenanted by the taker and Holder of every Security with every other taker and Holder of any Security and with the Trustee, that no one or more Holders of Securities of any series shall have any right in any manner whatever by virtue or by availing of any provision of this Indenture to affect, disturb or prejudice the rights of any other Holder of Securities, or to obtain or seek to obtain priority over or preference to any other such Holder or to enforce any right under this Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all Holders of Securities of such series. For the protection and enforcement of the provisions of this Section 6.6, each and every Holder of Securities of any series and the Trustee shall be entitled to such relief as can be given either at law or in equity.

Section 6.7 Unconditional Right of Securityholders to Institute Certain Suits.

Nothing contained in this Indenture or in the Securities of any series shall affect or impair the obligation of the Company, which is unconditional and absolute, to pay the principal of, and premium, if any, and interest, if any, on, and any Additional Amounts with respect to, the Securities of such series at the respective places, at the respective times, at the respective rates, in the respective amounts and in the coin or currency therein and herein prescribed, or affect or impair the right of action, which is also absolute and unconditional, of any Holder of any Security to institute suit to enforce such payment at the respective due dates expressed in such Security, or upon redemption, by declaration, repayment or otherwise as herein provided without reference to, or the consent of, the Trustee or the Holder of any other Security, unless such Holder consents thereto or unless and to the extent that the institution or prosecution.

Section 6.8 Powers and Remedies Cumulative; Delay or Omission Not Waiver of Default.

Except as provided in Section 6.6, no right or remedy herein conferred upon or reserved to the Trustee or to the Holder of any Security is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

No delay or omission of the Trustee or of any Holder of any Security of any series to exercise any right or power accruing upon any Event of Default occurring and continuing as aforesaid shall impair any such right or power or shall be construed to be a waiver of any such Event of Default or an acquiescence therein; and, subject to Section 6.6, every power and remedy given by this Indenture or by law to the Trustee or to the Holder of any Security may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Holder of such Security, as the case may be.

Section 6.9 Control by Holders of Securities.

The Holders of a majority in aggregate principal amount of the Securities of each series affected (with each series voting as a separate class) at the time Outstanding shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee with respect to the Securities of such series by this Indenture; provided that such direction shall not be otherwise than in accordance with law

34

and the provisions of this Indenture, and provided, further, that (subject to the provisions of Section 7.1) the Trustee shall have the right to decline to follow any such direction if the Trustee, being advised by counsel, shall determine that the action or proceeding so directed may not lawfully be taken or if the Trustee in good faith by its board of directors, the executive committee or a trust committee of directors or Responsible Officers of the Trustee shall determine that the action or proceedings so directed would expose the Trustee to personal liability or if the Trustee in good faith shall so determine that the actions or forebearances specified in or pursuant to such direction would be unduly prejudicial to the interests of Holders of the Securities of all series so affected not joining in the giving of said direction, it being understood that (subject to Section 7.1) the Trustee shall have no duty to ascertain whether or not such actions or forebearances are unduly prejudicial to such Holders.

As between the Trustee and the Holders of the Securities, nothing in this Indenture shall impair the right of the Trustee in its discretion to take any action deemed proper by the Trustee and which is not inconsistent with such direction or directions by Securityholders.

Section 6.10 Waiver of Past Defaults.

The Holders of not less than a majority in principal amount of the Outstanding Securities of any series on behalf of the Holders of all the Securities of such series may waive any past default hereunder with respect to such series and its consequences, except a default:

Upon any such waiver, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon.

Section 6.11 Trustee to Give Notice of Default, But May Withhold in Certain Circumstances.

The Trustee shall transmit to the Securityholders of any series, as the names and addresses of such Holders appear on the Security Register, notice by mail of all defaults that a Responsible Officer of the Trustee has actual knowledge of or with respect to which a Responsible Officer of the Trustee has received written notice which have occurred with respect to such series, such notice to be transmitted within 120 days after the occurrence thereof, unless such defaults shall have been cured before the giving of such notice (the term “default” or “defaults” for the purposes of this Section 6.11 being hereby defined to mean any event or condition which is, or with notice or lapse of time or both would become, an Event of Default); provided that, except in the case of default in the payment of the principal of, or premium, if any, or interest, if any, on, or any Additional Amounts with respect to, any of the Securities of such series, the Trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee or a trust committee of directors or Responsible Officers of the Trustee in good faith determines that the withholding of such notice is in the interests of the Securityholders of such series.

Section 6.12 Right of Court to Require Filing of Undertaking to Pay Costs.

The parties to this Indenture agree, and each Holder of any Security by his acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any

35

action taken, suffered or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section 6.12 shall not apply to any suit instituted by the Trustee, to any suit instituted by any Securityholder or group of Securityholders of any series holding in the aggregate more than 10% in aggregate principal amount of the Securities of such series Outstanding, or, in the case of any suit relating to or arising under Section 6.1(c) or Section 6.1(i) (if the suit relates to Securities of more than one but fewer than all series), 10% in aggregate principal amount of Securities Outstanding affected thereby, or, in the case of any suit relating to or arising under Section 6.1(c) or Section 6.1(i) (if the suit under Section 6.1(d) or Section 6.1(g) relates to all the Securities then Outstanding), Section 6.1(f) or Section 6.1(g), 10% in aggregate principal amount of all Securities Outstanding, or to any suit instituted by any Holder of Securities for the enforcement of the payment of the principal of, or premium, if any, or interest, if any, on, any Security on or after the due date expressed in such Security.

Section 6.13 Waiver of Usury, Stay or Extension Laws.

The Company covenants that (to the extent that it may lawfully do so) it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any usury, stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Company expressly waives (to the extent that it may lawfully do so) all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

ARTICLE VII

CONCERNING THE TRUSTEE

Section 7.1 Duties and Responsibilities of the Trustee; During Default; Prior to Default.

With respect to the Holders of any series of Securities issued hereunder, the Trustee, prior to the occurrence of an Event of Default with respect to the Securities of that series and after the curing or waiving of all Events of Default which may have occurred with respect to such series, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture. In case an Event of Default with respect to the Securities of a series has occurred (which has not been cured or waived), the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent man would exercise or use under the circumstances in the conduct of his own affairs.

No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that:

36

Every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section 7.1

None of the provisions contained in this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur personal financial liability in the performance of any of its duties or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that the repayment of such funds or adequate indemnity against such liability is not reasonably assured to it.

Section 7.2 Certain Rights of the Trustee.

Subject to Section 7.1:

37

38

Section 7.3 Trustee Not Responsible for Recitals, Disposition of Securities or Application of Proceeds Thereof.

The recitals contained herein and in the Securities, except the certificates of authentication, shall be taken as the statements of the Company, and the Trustee assumes no responsibility for the correctness of the same, except that the Trustee represents that it is duly authorized to execute and deliver this Indenture, authenticate the Securities and perform its obligations hereunder and that the statements made by it in a Statement of Eligibility on Form T-1 supplied to the Company are true and accurate, subject to the qualifications set forth therein. The Trustee makes no representation as to the validity or sufficiency of this Indenture or of the Securities. The Trustee shall not be accountable for the use or application by the Company of any of the Securities or of the proceeds thereof.

Section 7.4 Trustee and Agents May Hold Securities; Collections, etc.

The Trustee, any Paying Agent, Securities Registrar or any agent of the Company or the Trustee, in its individual or any other capacity, may become the owner or pledgee of Securities with the same rights it would have if it were not the Trustee or such agent, and, subject to Section 7.8 and Section 7.13, if operative, may otherwise deal with the Company and receive, collect, hold and retain collections from the Company with the same rights it would have if it were not the Trustee, Paying Agent, Securities Registrar or such agent.

Section 7.5 Moneys Held by Trustee.

Subject to the provisions of Section 12.3, all moneys received by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received, but need not be segregated from other funds except to the extent required by mandatory provisions of law. The Trustee shall have no liability for interest on money it receives and holds in trust except as specifically provided herein.

Section 7.6 Compensation and Indemnification of Trustee and Its Prior Claim.

The Company covenants and agrees to pay the Trustee from time to time, and the Trustee shall be entitled to such compensation as the Company and the Trustee may from time to time agree in writing for all services rendered by the Trustee hereunder (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust) and the Company covenants and agrees to pay or reimburse the Trustee and each predecessor trustee upon its request for all reasonable and properly incurred expenses, disbursements and advances incurred or made by or on behalf of it in accordance with any of the provisions of this Indenture (including the reasonable compensation and the expenses and disbursements of its counsel and of all agents and other Persons not regularly in its employ) except any such expense, disbursement or advance as shall be attributable to its negligence or bad faith. The Company also covenants to indemnify the Trustee (which shall be deemed to include its directors, officers, employees and agents) and each predecessor trustee for, and hold it harmless against, any loss, liability, damage, claims or expense (including the fees and expenses of its counsel), including taxes (other than taxes

39

measured by the income of the Trustee or otherwise applicable to the Trustee for operations outside the scope of this Indenture) incurred without negligence or bad faith on its part, arising out of or in connection with the acceptance or administration of this Indenture or the trusts hereunder and the performance of its duties hereunder, including the costs and expenses of defending itself against or investigating any claim of liability in connection with the exercise or performance of any of its powers or duties hereunder except to the extent that any such loss, liability, damage, claims or expense shall be attributable to the Trustee’s negligence or bad faith. The obligations of the Company under this Section 7.6 to compensate and indemnify the Trustee and each predecessor trustee and to pay or reimburse the Trustee and each predecessor trustee for expenses, disbursements and advances shall constitute additional indebtedness hereunder and shall survive the satisfaction and discharge of this Indenture and resignation or removal of the Trustee. Such additional indebtedness shall be a Lien prior to that of the Securities upon all property and funds held or collected by the Trustee as such, except funds held in trust for the benefit of the Holders of particular Securities.

Section 7.7 Right of Trustee to Rely on Officer’s Certificate, etc.

Subject to Section 7.1 and Section 7.2, whenever in the administration of the trusts of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking or suffering or omitting any action hereunder, such matter (unless other evidence in respect thereof be herein specifically prescribed) may, in the absence of negligence or bad faith on the part of the Trustee, be deemed to be conclusively proved and established by an Officer’s Certificate delivered to the Trustee, and such certificate, in the absence of negligence or bad faith on the part of the Trustee, shall be full warrant to the Trustee for any action taken, suffered or omitted by it under the provisions of this Indenture upon the good faith thereof.

Section 7.8 Qualification of Trustee; Conflicting Interests.

The Trustee for the Securities of any series issued hereunder shall be subject to the provisions of Section 310(b) of the Trust Indenture Act during the period of time provided for therein. In determining whether the Trustee has a conflicting interest as defined in Section 310(b) of the Trust Indenture Act with respect to the Securities of any series, there shall be excluded this Indenture with respect to Securities of any particular series of Securities other than that series. Nothing herein shall prevent the Trustee from filing with the Commission the application referred to in the penultimate paragraph of Section 310(b) of the Trust Indenture Act.

Section 7.9 Persons Eligible for Appointment as Trustee.

There shall at all times be a Trustee hereunder for each series of Securities, which shall be at all times either:

40

Section 7.10 Resignation and Removal; Appointment of Successor Trustee.

41

Section 7.11 Acceptance of Appointment by Successor Trustee.

Any successor trustee appointed as provided in Section 7.10 shall execute, acknowledge and deliver to the Company and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee, without any further act, deed or conveyance, shall become vested with all rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as trustee hereunder; but nevertheless, on the written request of the Company or of the successor trustee, upon payment of all amounts due to the Trustee under Section 7.6, the Trustee ceasing to act shall, subject to Section 4.4, pay over to the successor trustee all moneys at the time held by it hereunder and shall execute and deliver an instrument transferring to such successor trustee all such rights, powers, duties and obligations. Upon request of any successor trustee, the Company shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor trustee all such rights and powers. Any Trustee ceasing to act, shall, nevertheless, retain a prior Lien upon all property or funds held or collected by such trustee to secure any amounts then due it pursuant to the provisions of Section 7.6.

No successor trustee shall accept appointment as provided in this Section 7.11 unless at the time of such acceptance such successor trustee shall be qualified under the provisions of Section 7.8 and eligible under the provisions of Section 7.9.

Upon acceptance of appointment by any successor trustee as provided in this Section 7.11, the Company shall mail notice thereof by first-class mail to the Holders of Securities at their last addresses as they shall appear on the Security Register. If the acceptance of appointment is substantially contemporaneous with the resignation, then the notice called for by the preceding sentence may be combined with the notice called for by Section 7.10. If the Company fails to mail such notice within 10 days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be mailed at the expense of the Company.

Section 7.12 Merger, Conversion, Consolidation or Succession to Business of Trustee.

Any corporation in which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to substantially all of the corporate trust business of the Trustee, shall be the successor of the trustee hereunder, provided that such corporation shall be qualified under the provisions of Section 7.8 and eligible under the provisions of Section 7.9, without the execution or filing of any paper or any further act (including the giving of any notice to Securityholders) on the part of any of the parties hereto, anything herein to the contrary notwithstanding.

42

In case at the time such successor to the Trustee shall succeed to the trusts created by this Indenture any of the Securities shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee and deliver such Securities so authenticated; and, in case at that time any of the Securities shall not have been authenticated, any successor to the Trustee may authenticate such Securities either in the name of any predecessor hereunder or in the name of the successor trustee; and in all such cases such certificate shall have the full force which it is anywhere in the Securities or in this Indenture provided for the certificate of authentication of the Trustee.

Section 7.13 Preferential Collection of Claims Against the Company.

Nothing herein contained, however, shall affect the right of the Trustee:

43

For the purposes of Section 7.13(a)(ii)(B), (C) and (D), property substituted after the beginning of such three months’ period for property held as security at the time of such substitution shall, to the extent of the fair value of the property released, have the same status as the property released, and, to the extent that any claim referred to in any of such paragraphs is created in renewal of or in substitution for or for the purpose of repaying or refunding any pre-existing claim of the Trustee as such creditor, such claim shall have the same status as such pre-existing claim.

If the Trustee shall be required to account, the funds and property held in such special account and the proceeds thereof shall be apportioned between the Trustee, the Holders of the Securities and the holders of other indenture securities in such manner that the Trustee, such Holders and the holders of other indenture securities realize, as a result of payments from such special account and payments of dividends on claims filed against the Company in bankruptcy or receivership or in proceedings for reorganization pursuant to the Federal Bankruptcy Code or applicable state law, the same percentage of their respective claims, figured before crediting to the claim of the Trustee anything on account of the receipt by it from the Company of the funds and property in such special account and before crediting to the respective claims of the Trustee, Holders of the Securities and the holders of other indenture securities dividends on claims filed against the Company in bankruptcy or receivership or in proceedings for reorganization pursuant to the Federal Bankruptcy Code or applicable state law, but after crediting thereon receipts on account of the indebtedness represented by their respective claims from all sources other than from such dividends and from the funds and property so held in such special account. As used in this Section 7.13(a)(ii), with respect to any claim, the term “dividends” shall include any distribution with respect to such claim, in bankruptcy or receivership or in proceedings for reorganization pursuant to the Federal Bankruptcy Code or applicable state law, whether such distribution is made in cash, securities or other property, but shall not include any such distribution with respect to the secured portion, if any, of such claim. The court in which such bankruptcy, receivership or proceeding for reorganization is pending shall have jurisdiction (i) to apportion between the Trustee, the Holders of Securities and the holders of other indenture securities, in accordance with the provisions of this Section 7.13(a)(ii), the funds and property held in such special account and the proceeds thereof; or (ii) in lieu of such apportionment, in whole or in part, to give to the provisions of this Section 7.13(a)(ii) due consideration in determining the fairness of the distributions to be made to the Trustee, the Holders of Securities and the holders of other indenture securities with respect to their respective claims, in which event it shall not be necessary to liquidate or to appraise the value of any securities or other property held in such special account or as security for any such claim, or to make a specific allocation of such distribution as between the secured and unsecured portions of such claims, or otherwise to apply the provisions of this Section 7.13(a)(ii) as a mathematical formula.

44

Any Trustee who has resigned or been removed after the beginning of such three months’ period shall be subject to the provisions of this Section 7.13(a) as though such resignation or removal had not occurred. If any Trustee has resigned or been removed prior to the beginning of such three months’ period, it shall be subject to the provisions of this Section 7.13(a) if and only if the following conditions exist:

45

CONCERNING THE HOLDERS OF SECURITIES

Section 8.1 Action by Holders.

Whenever in this Indenture it is provided that the Holders of a specified percentage in aggregate principal amount of the Securities of any series may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or the taking of any other action) the fact that at the time of taking any such action the Holders of such specified percentage have joined therein may be evidenced (a) by any instrument or any number of instruments of similar intention executed by Holders in Person or by agent or proxy appointed in writing, or (b) by the record of Holders voting in favor thereof at any meeting of such Holders duly called and held in accordance with the provisions of Article IX, or (c) by a combination of such instrument or instruments and any such record of such a meeting of Holders. The Company may (but shall not be required to) set a record date for purposes of determining the identity of Securityholders entitled to vote or consent to any action by vote or consent authorized or permitted under this Indenture, which record date shall be the later of 10 days prior to the first solicitation of such consent or the date of the most recent list of Holders furnished to the Trustee pursuant to Section 5.1 of this Indenture prior to such solicitation. If a record date is fixed, those Persons who were Securityholders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to take such action by vote or consent or to revoke any vote or consent previously given, whether or not such Persons continue to be Holders after such record date.

Section 8.2 Proof of Execution of Instruments by Holders of Securities.

Subject to Section 7.1, Section 7.2 and Section 9.5, the execution of any instrument by a Holder of a Security or his agent or proxy may be proved in any reasonable manner that the Trustee deems sufficient, including, without limitation, in the following manner:

The fact and date of the execution by any such Person of any instrument may be proved by the certificate of any notary public or other officer authorized to take acknowledgments of deeds, that the Person executing such instrument acknowledged to him the execution thereof, or by an affidavit or written statement of a witness to such execution. Where such execution is by an officer of a corporation or association or a member of a partnership on behalf of such corporation, association or partnership, as the case may be, or by any other Person acting in a representative capacity, such certificate, affidavit or written statement shall also constitute sufficient proof of his authority.

The ownership of Securities shall be proved by the Securities Register or by a certificate of the Securities Registrar.

The record of any Holders’ meeting shall be proved in the manner provided in Section 9.6.

Section 8.3 Holders to be Treated as Owners.

The Company, the Trustee and any agent of the Company or the Trustee may deem and treat the Person in whose name any Security shall be registered upon the Security Register as the absolute owner of such Security (notwithstanding any notation of ownership or other writing thereon) for the purpose of receiving payment of principal of, and premium, if any, and (subject to Section 3.5 and Section 3.7) interest, if any, on, such Security, and for all other purposes whatsoever, whether or not such Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary. All such payments so made to any Holder for the time being, shall be valid, and, to the extent of the sum or sums so paid, effectual to satisfy and discharge the liability for moneys payable upon such Security.

None of the Company, the Trustee or 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 interest of a Global Security, or for maintaining, supervising or reviewing any records relating to such beneficial ownership interest. Notwithstanding the foregoing, with respect to any Global Security, nothing herein shall prevent the Company or the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by any Depository (or its nominee), as a Holder, with respect to such Global Security or impair, as between such Depository and owners of beneficial interests in such Global Security, the operation of customary practices governing the exercise of the right of such Depository (or its nominee) as Holder of such Global Security.

Section 8.4 Securities Owned by Company Deemed Not Outstanding.

In determining whether the Holders of the requisite aggregate principal amount of Securities of any or all series have concurred in any direction, consent or waiver under this Indenture, Securities which are owned by the Company or any other obligor on the Securities with respect to which such determination is being made or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or any other obligor on the Securities with respect to which such determination is being made shall be disregarded and deemed not to be Outstanding for the purpose of any such determination, except that for the purpose of determining whether the Trustee shall be protected in relying on any such direction, consent or waiver only Securities which the Trustee knows are so owned shall be so disregarded. Securities so owned which have been pledged in good faith may be regarded as Outstanding if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right so to act with respect to such Securities and that the pledgee is not the Company or any other obligor upon the Securities or any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or any other obligor on the Securities. In case of a dispute as to such right, the advice of counsel shall be full protection in respect of any decision made by the Trustee in accordance with such advice. Upon request of the Trustee, the Company shall furnish to the Trustee promptly an Officer’s

47

Certificate listing and identifying all Securities, if any, known by the Company to be owned or held by or for the account of any of the above-described Persons; and, subject to Section 7.1 and Section 7.2, the Trustee shall be entitled to accept such Officer’s Certificate as conclusive evidence of the facts therein set forth and of the fact that all Securities not listed therein are Outstanding for the purpose of any such determination.

Section 8.5 Right of Revocation of Action Taken.

At any time prior to (but not after) the evidencing to the Trustee, as provided in Section 8.1, of the taking of any action by the Holders of the percentage in aggregate principal amount of the Securities of any or all series, as the case may be, specified in this Indenture in connection with such action, any Holder of a Security, the number, letter or other distinguishing symbol of which is shown by the evidence to be included in the Securities the Holders of which have consented to such action, may, by filing written notice at the Corporate Trust Office and upon proof of holding as provided in this Article VIII, revoke such action so far as concerns such Security. Except as aforesaid, any such action taken by the Holder of any Security shall be conclusive and binding upon such Holder and upon all future Holders and owners of such Security and of any Securities issued in exchange or substitution therefor, irrespective of whether or not any notation in regard thereto is made upon any such Security or such other Security. Any action taken by the Holders of the percentage in aggregate principal amount of the Securities of any or all series, as the case may be, specified in this Indenture in connection with such action shall be conclusively binding upon the Company, the Trustee and the Holders of all the Securities affected by such action.

ARTICLE IX

HOLDERS’ MEETINGS

The Trustee may at any time call a meeting of Holders of Securities to take any action specified in Section 9.1, to be held at such time and at such place in the Borough of Manhattan, The City of New York, or such other Place of Payment, as the Trustee shall determine. Notice of every meeting of the Holders of Securities, setting forth the time and the place of such meeting, and in general terms the action proposed to be taken at such meeting, shall be given to Holders of Securities of the particular series in the manner and to the extent provided in Section 13.4. Such notice shall be given not less than 20 nor more than 90 days prior to the date fixed for the meeting.

48

Section 9.3 Call of Meetings by Company or Holders.

In case at any time the Company, pursuant to a resolution of its Board of Directors, or the Holders of at least 10% in aggregate principal amount of the Outstanding Securities of any or all series, as the case may be, shall have requested the Trustee to call a meeting of Holders of Securities of any or all series, as the case may be, by written request setting forth in reasonable detail the action proposed to be taken at the meeting, and the Trustee for such series shall not have given the notice of such meeting within 20 days after receipt of such request, then the Company or such Holders may determine the time and the place in the Borough of Manhattan or other Place of Payment for such meeting and may call such meeting to take any action authorized in Section 9.1, by giving notice thereof as provided in Section 9.2.

Section 9.4 Qualifications for Voting.

To be entitled to vote at any meeting of Holders a Person shall be (a) a Holder of one or more outstanding Securities with respect to which such meeting is being held or (b) a Person appointed by an instrument in writing as proxy by such ▇▇▇▇▇▇. The only Persons who shall be entitled to be present or to speak at any meeting of Holders shall be the Persons entitled to vote at such meeting and their counsel and any representatives of the Trustee and its counsel and any representatives of the Company and its counsel.

Section 9.5 Regulations.

Notwithstanding any other provisions of this Indenture, the Trustee may make such reasonable regulations as it may deem advisable for any meeting of Holders of the Securities in regard to proof of the holding of Securities and of the appointment of proxies, and in regard to the appointment and duties of inspectors of votes, the submission and examination of proxies, certificates and other evidence of the right to vote, and such other matters concerning the conduct of the meeting as it shall think fit.

The Trustee shall, by an instrument in writing, appoint a temporary chairman of the meeting, unless the meeting shall have been called by the Company or by Holders of Securities as provided in Section 9.3, in which case the Company or the Holders calling the meeting, as the case may be, shall in like manner appoint a temporary chairman. A permanent chairman and a permanent secretary of the meeting shall be elected by majority vote of the meeting.

Subject to Section 8.4, at any meeting each Holder of Securities with respect to which such meeting is being held or proxy therefor shall be entitled to one vote for each $1,000 principal amount (in the case of Original Issue Discount Securities, such principal amount to be determined as provided in the definition of “Outstanding”) of Securities held or represented by him; provided, however, that no vote shall be cast or counted at any meeting in respect of any such Security challenged as not Outstanding and ruled by the chairman of the meeting to be not Outstanding. The chairman of the meeting shall have no right to vote other than by virtue of Securities held by him or instruments in writing aforesaid duly designating him as the Person to vote on behalf of other Holders. At any meeting of Holders, the presence of Persons holding or representing Securities with respect to which such meeting is being held in an aggregate principal amount sufficient to take action on the business for the transaction of which such meeting was called shall constitute a quorum, but, if less than a quorum is present, the Persons holding or representing a majority in aggregate principal amount of such Securities represented at the meeting may adjourn such meeting with the same effect, for all intents and purposes, as though a quorum had been present. Any meeting of Holders of Securities with respect to which a meeting was duly called pursuant to the provisions of Section 9.2 or Section 9.3 may be adjourned from time to time by Persons holding or representing a majority in aggregate principal amount of such Securities represented at the meeting, present, whether or not constituting a quorum, and the meeting may be held as so adjourned without further notice.

49

Section 9.6 Voting.

The vote upon any resolution submitted to any meeting of Holders of Securities with respect to which such meeting is being held shall be by written ballots on which shall be subscribed the signatures of such Holders or of their representatives by proxy and the serial number or numbers of the Securities held or represented by them. The permanent chairman of the meeting shall appoint two inspectors of votes who shall count all votes cast at the meeting for or against any resolution and who shall make and file with the secretary of the meeting their verified written reports in duplicate of all votes cast at the meeting. A record in duplicate of the proceedings of each meeting of holders shall be prepared by the secretary of the meeting and there shall be attached to said record the original reports of the inspectors of votes on any vote by ballot taken thereat and affidavits by one or more Persons having knowledge of the facts setting forth a copy of the notice of the meeting and showing that said notice was mailed as provided in Section 9.2. The record shall show the serial numbers of the Securities voting in favor of or against any resolution. The record shall be signed and verified by the affidavits of the permanent chairman and secretary of the meeting and one of the duplicates shall be delivered to the Company and the other to the Trustee to be preserved by the Trustee.

Any record so signed and verified shall be conclusive evidence of the matters therein stated.

Section 9.7 No Delay of Rights by Reason of Meeting.

Nothing in this Article IX contained shall be deemed or construed to authorize or permit, by reason of any call of a meeting of Holders or any rights expressly or impliedly conferred hereunder to make such call, any hindrance or delay in the exercise of any right or rights conferred upon or reserved to the Trustee or to the Holders under any of the provisions of this Indenture or of the Securities of any series.

50

51

The Trustee is hereby authorized to join with the Company in the execution of any such supplemental indenture, to make any further appropriate agreements and stipulations, which may be therein contained and to accept the conveyance, transfer, assignment, mortgage or pledge of any property thereunder, but the Trustee shall not be obligated to enter into any such supplemental indenture which affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise.

Any supplemental indenture authorized by the provisions of this Section 10.1 may be executed without the consent of the Holders of any of the Securities at the time Outstanding, notwithstanding any of the provisions of Section 10.2.

Section 10.2 Supplemental Indentures With Consent of Securityholders.

With the consent (evidenced as provided in Article VIII) of the Holders of not less than a majority in aggregate principal amount of the Securities at the time Outstanding of all series affected by such supplemental indenture (voting as one class), the Company, when authorized by a resolution of its Board of Directors, and the Trustee may, from time to time and at any time, enter into an indenture or indentures supplemental hereto (which shall conform to the provisions of the Trust Indenture Act as in force at the date of execution thereof) for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or of any supplemental indenture or of modifying in any manner the rights of the Holders of the Securities of each such series; provided that no such supplemental indenture shall (a) change the Stated Maturity of the principal of, or any premium or installment of interest on or any Additional Amounts with respect to, any Security of such series, or reduce the principal amount thereof (or modify the calculation of such principal amount) or rate of interest thereon or any Additional Amounts with respect thereto (or modify the calculation of such rate), or any premium payable on redemption thereof or otherwise, or reduce the amount of the principal of an Original Issue Discount Security that would be due and payable upon an acceleration with respect thereto pursuant to Section 6.1 or the amount thereof provable in bankruptcy pursuant to Section 6.2, or change the obligation of the Company to pay Additional Amounts pursuant to Section 4.4 (except as contemplated by Section 11.1 and permitted by Section 10.1), or change the redemption provisions or, following the occurrence of any event that would entitle a holder to require the Company to redeem or repurchase the Securities at the option of the Holder, adversely affect the right of redemption on repurchase at the option of such Holder, or change the Place of Payment, currency in which the principal of, any premium or interest on, or any Additional Amounts with respect to any security is payable, or impair or adversely affect the right of any Securityholder to institute suit for the payment thereof or, if the Securities provide therefor, any right of repayment at the option of the Securityholder, without the consent of the Holder of each Security of such series so affected; or (b) reduce the aforesaid percentage of the principal amount of Securities Outstanding of such series, the consent of the Holders of which is required for any such supplemental indenture or any waiver of any obligations of the Company under this Indenture, without the consent of the Holders of each Security of such series so affected, or reduce the

52

requirements for quorum on voting; or (c) modify any of the provisions of this Section 10.2, Section 6.10 or Section 4.9, except to increase any such percentage or to provide that certain other provisions of this Indenture cannot be modified without the consent of the Holder of each Outstanding Security thereby.

Upon the request of the Company, accompanied by a Board Resolution authorizing the execution of any such supplemental indenture, and upon the filing with the Trustee of evidence of the consent of Securityholders as aforesaid and other documents, if any, required by Section 8.1, the Trustee shall join with the Company in the execution of such supplemental indenture unless such supplemental indenture affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such supplemental indenture.

It shall not be necessary for the consent of the Securityholders under this Section 10.2 to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such consent shall approve the substance thereof.

A supplemental indenture which changes or eliminates any covenant or other provision of this Indenture which has expressly been included solely for the benefit of one or more particular series of Securities, or which modifies the rights of the Holders of Securities of such series with respect to such covenant or other provision, shall be deemed not to affect the rights under this Indenture of the Holders of Securities of any other series.

Section 10.3 Notice of Supplemental Indenture.

Promptly after the execution by the Company and the Trustee of any supplemental indenture pursuant to the provisions of Section 10.2, the Company shall mail a notice thereof by first-class mail to the Holders of Securities of each series affected thereby at their addresses as they shall appear on the Security Register, setting forth in general terms the substance of such supplemental indenture. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such supplemental indenture.

Section 10.4 Effect of Supplemental Indenture.

Upon the execution of any supplemental indenture pursuant to the provisions of this Article X, this Indenture shall be and be deemed to be modified and amended in accordance therewith, but only with regard to the Securities of each series affected by such supplemental indenture, and the respective rights, limitations of rights, obligations, duties and immunities under this Indenture of the Trustee, the Company and the Holders of any Securities of such series affected thereby shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments, and all the terms and conditions of any such supplemental indenture shall be and be deemed to be part of the terms and conditions of this Indenture for any and all purposes with regard to the Securities of such series.

Section 10.5 Documents To Be Given to Trustee.

The Trustee, subject to the provisions of Section 7.1 and Section 7.2, shall be provided with an Officer’s Certificate and an Opinion of Counsel as conclusive evidence that any supplemental indenture executed pursuant to this Article X complies with the applicable provisions of this Indenture and is authorized or permitted by this Indenture.

Section 10.6 Notation on Securities in Respect of Supplemental Indentures.

Securities of any series affected by any supplemental indenture which are authenticated and delivered after the execution of such supplemental indenture pursuant to the provisions of this Article X may bear a notation in form approved by the Company and the Trustee as to any matter provided

53

for in such supplemental indenture. If the Company shall so determine, new Securities of any series so modified as to conform, in the opinion of the Company, to any modification of this Indenture contained in any such supplemental indenture may be prepared by the Company, authenticated by the Trustee and delivered in exchange for the Securities of such series then Outstanding.

61

law or in equity or by constitution or statute, of, and any and all such rights and claims against, every such incorporator, shareholder, officer or director, as such, because of the creation of the indebtedness hereby authorized, or under or by reason of the obligations, covenants or agreements contained in this Indenture or in any Security or implied therefrom, are hereby expressly waived and released as a condition of, and as a consideration for, the execution of this Indenture and the issuance of such Security.

Section 13.2 Provisions of Indenture for the Sole Benefit of Parties and Securityholders.

Nothing in this Indenture or in the Securities, expressed or implied, shall give or be construed to give to any Person, other than the parties hereto and their successors and the Holders of the Securities, any legal or equitable right, remedy or claim under this Indenture or under any covenant or provision herein contained, all such covenants and provisions being for the sole benefit of the parties hereto and their successors and the Holders of the Securities.

In the case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder. In case by reason of the suspension of publication of any Authorized Newspapers or by reason of any other cause it shall be impracticable to publish any notice to Holders otherwise required or permitted under this Indenture, then such notification as shall be given with the approval of the Trustee shall constitute sufficient notice to such Holders for every purpose hereunder.

Section 13.16 Electronic Means.

The Trustee shall have the right to accept and act upon instructions, including funds transfer instructions (“Instructions”) given pursuant to this Indenture and related financing documents and delivered using Electronic Means; provided, however, that the Company shall provide to the Agent an incumbency certificate listing officers with the authority to provide such Instructions (“Authorized Officers”) and containing specimen signatures of such Authorized Officers, which incumbency certificate shall be amended by the Company whenever a person is to be added or deleted from the listing. If the Company elects to give the Trustee Instructions using Electronic Means and the Trustee in its discretion elects to act upon such Instructions, the Trustee’s understanding of such Instructions shall be deemed controlling. The Company understands and agrees that the Trustee cannot

determine the identity of the actual sender of such Instructions and that the Trustee shall conclusively presume that directions that purports to have been sent by an Authorized Officer listed in the incumbency certificate provided to the Trustee have been sent by an Authorized Officer listed on the incumbency certificate provided to the Trustee have been sent by such Authorized Officer. The Company shall be responsible for ensuring that only Authorized Officers transmit such Instructions to the Trustee and that the Company and all Authorized Officers are solely responsible to safeguard the use and confidentiality of applicable user and authorization codes, passwords and/or authentication keys upon receipt by the Company.

The Company agrees: (i) to assume all risks arising out of the use of Electronic Means to submit Instructions to the Trustee, including without limitation the risk of the Trustee acting on unauthorized Instructions, and the risk of interception and misuse by third parties;(ii) that it is fully informed of the protections and risks associated with the various methods of transmitting Instructions to the Trustee and that there may be more secure methods of transmitting Instructions than the method(s) selected by the Company and/or any obligor, as applicable; (iii) that the security procedures (if any) to be followed in connection with its transmission of Instructions provide to it a commercially reasonable degree of protection in light of its particular needs and circumstances; and (iv) to notify the Trustee immediately upon learning of any compromise or unauthorized use of the security procedures. “Electronic Means” shall mean the following communications methods: email, facsimile transmission, secure electronic transmission containing applicable authorization codes, passwords and/or authentication keys issued by the Trustee, or another method or system specified by the Trustee as available for use in connection with its services hereunder.

ARTICLE XIV

REDEMPTION OF SECURITIES

Section 14.1 Applicability of Article.

The provisions of this Article XIV shall be applicable to the Securities of any series which are redeemable before their Stated Maturity except as otherwise specified as contemplated by Section 3.1 for Securities of such series.

Section 14.2 Notice of Redemption; Selection of Securities.

In case the Company shall desire to exercise the right to redeem all or, as the case may be, any part of the Securities of any series in accordance with their terms, it shall fix a Redemption Date and shall provide notice of such redemption at least 45 days prior to such Redemption Date to the Trustee and at least 30 days but no more than 60 days prior to such Redemption Date to the Holders of Securities of such series so to be redeemed as a whole or in part in the manner provided in Section 13.4, unless a different period is specified in the Securities to be redeemed. The notice

66

provided in the manner herein specified shall be conclusively presumed to have been duly given, whether or not the Holder receives such notice. In any case, failure to give such notice or any defect in the notice to the Holder of any Security of a series designated for redemption as a whole or in part shall not affect the validity of the proceedings for the redemption of any other Security of such series.

Each such notice of redemption shall specify the Redemption Date, the record date, Redemption Price, the CUSIP, Common Code, ISIN or other comparable number, the Place or Places of Payment, that the Securities of such series are being redeemed at the option of the Company pursuant to provisions contained in the terms of the Securities of such series or in a supplemental indenture establishing such series, if such be the case, together with a brief statement of the facts permitting such redemption, that payment will be made upon presentation and surrender of the applicable Securities at the Place or Places of Payment, that the Redemption Price together with any interest accrued and Additional Amounts to the Redemption Date will be paid as specified in said notice, and that on and after said Redemption Date any interest thereon or on the portions thereof to be redeemed will cease to accrue, and any information that is required to be included therein by the Depository.

If fewer than all the Securities of any series are to be redeemed the notice of redemption shall specify the numbers of the Securities of such series to be redeemed. In case any Security of any series is to be redeemed in part only, the notice of redemption shall state the portion of the principal amount thereof to be redeemed and shall state that on and after the Redemption Date, upon surrender of such Security, a new Security or Securities of such series in principal amount equal to the unredeemed portion thereof will be issued, or, in the case of Securities providing appropriate space for such notation, at the option of the Holders the Trustee, in lieu of delivering a new Security or Securities as aforesaid, may make a notation on such Security of the payment of the redeemed portion thereof.

On or before the Redemption Date with respect to the Securities of any series stated in the notice of redemption given as provided in this Section 14.2, the Company will deposit with the Trustee or with one or more Paying Agents an amount of money (except as otherwise specified as contemplated by Section 3.1 for the Securities of such series or if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 4.3) sufficient to redeem on such Redemption Date all the Securities or portions thereof so called for redemption at the applicable Redemption Price, together with accrued interest on and Additional Amounts with respect thereto, to such Redemption Date.

If fewer than all the Securities of any series, or any Tranche thereof, are to be redeemed, the Company shall give notice of redemption to the Trustee not less than 60 days prior to the Redemption Date as to the aggregate principal amount of Securities to be redeemed.

If a Holders’ Redemption Agreement, as hereinafter defined, is not on file with the Trustee and in effect, the particular Securities to be redeemed shall be selected by the Trustee, from the Outstanding Securities of such series or Tranche not previously called for redemption, substantially pro rata, by lot or by any other method the Trustee considers fair and appropriate and that complies with the requirements of the principal national securities exchange, if any, on which such Securities are listed, and which may provide for the selection for redemption of portions (equal to the minimum authorized denomination for Securities of that series or Tranche or any integral multiple thereof) of the principal amount of Securities of such series or Tranche of a denomination larger than the minimum authorized denomination for Securities of that series or Tranche; provided that in the event that the Securities of such series or Tranche have different terms and maturities, the Securities to be redeemed shall be selected by the Company and the Company shall give notice thereof to the

67

Trustee; provided, however, that if, as indicated in an Officer’s Certificate, the Company shall have offered to purchase all or any principal amount of the Securities then Outstanding of any series, or any Tranche thereof, and fewer than all of such Securities as to which such offer was made shall have been tendered to the Company for such purchase, the Trustee, if so directed by Company Order, shall select for redemption all or any principal amount of such Securities which have not been so tendered.

If the Trustee shall use “CUSIP”, “Common Code” or “ISIN” numbers in notices as a convenience to Holders, then any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee in writing of any change in the “CUSIP”, “Common Code” or “ISIN” numbers.

If at the time the Company shall have given notice of redemption to the Trustee in accordance with Section 14.2, there shall be on file with the Trustee and in effect a Holders’ Redemption Agreement, as hereinafter defined, then the Trustee shall select, in accordance with the provisions of said Holders’ Redemption Agreement, the Securities or parts thereof to be redeemed.

For the purposes of this Indenture, the term “Holders’ Redemption Agreement” shall mean an agreement, reasonably satisfactory to the Trustee, executed as provided in this Section 14.2, which provides for the method to be followed by the Trustee in selecting Securities or parts of Securities for redemption out of any funds held by the Trustee to be applied to such redemption. A Holders’ Redemption Agreement may be made with respect to a single series of Securities, or Tranche thereof, in which case it shall be executed by or on behalf of the Holders of all Outstanding Securities of such series or Tranche, or it may be made with respect to all Outstanding Securities in which case it shall be executed by or on behalf of the Holders of all Securities Outstanding hereunder.

The Trustee shall promptly notify the Company in writing of the Securities selected for redemption and, in the case of any Securities selected for partial redemption, the principal amount thereof to be redeemed.

Section 14.3 Payment of Securities Called for Redemption.

If notice of redemption has been given as above provided and the Company has deposited, on or before the Redemption Date, with the Trustee (and/or having irrevocably directed the Trustee to apply, from money held by it available to be used for the redemption of Securities) an amount in cash sufficient to redeem all of the Securities to be redeemed, the Securities or portions of Securities of the series specified in such notice shall become due and payable on the Redemption Date, and at the place or places stated in such notice at the applicable Redemption Price, together with any interest accrued to such Redemption Date, and on and after said Redemption Date any interest on the Securities or portion of Securities of any series so called for redemption shall cease to accrue. On presentation and surrender of such Securities at a Place of Payment in such notice specified, such Securities or the specified portions thereof shall be paid and redeemed by the Company at the applicable Redemption Price, together with any interest accrued and Additional Amounts to the Redemption Date, except that if such Redemption Date is an Interest Payment Date, interest shall be paid as provided in Section 3.7.

Upon presentation of any Security redeemed in part only, the Company shall execute and the Trustee shall authenticate and make available for delivery to or on the order of the Holder thereof, at the expense of the Company, a new Security or Securities of such series, of authorized denominations, in principal amount equal to the unredeemed portion of the Security so presented.

68

If a Security in global form is so surrendered, the Company shall execute, and the Trustee shall authenticate and deliver to the U.S. Depository or other Depository for such Security in global form as shall be specified in the Company Order with respect thereto to the Trustee, without service charge, a new Security in global form in a denomination equal to and in exchange for the unredeemed portion of the principal of the Security in global form so surrendered.

If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal and any premium, until paid, shall bear interest from the Redemption Date at the rate prescribed therefor in the Security.

The provisions of this Article XV shall be applicable to the Securities of any series if specified by Section 3.1 for Securities of such series.

Section 15.2 Redemption of Securities issued by the Company at the Option of Holders.

then the Holders of each Security of such series issued by the Company will have the option upon the giving of a Put Notice (as defined in Section 15.5) to require the Company to redeem or, at the option of the Company, purchase (or procure the purchase of) such Security on the Put Date (as defined in Section 15.5) at 101% of its principal amount together with accrued interest to the Put Date. The Restructuring Event and Rating Downgrade or the Restructuring Event and Negative Rating Event, as the case may be, occurring within the Restructuring Period, are together referred to as a “Put Event.”

If the provisions of this Article XV shall be applicable to the Securities of a series pursuant to Section 3.1, then promptly upon the Company becoming aware that a Put Event has occurred, the Company shall and if so requested in writing by the Holders of at least a majority in aggregate principal amount of the Securities of the applicable series then Outstanding, the Trustee shall, give notice (a “Put Event Notice”) to the Holders of the relevant series of Securities in accordance with Section 13.4 specifying the nature of the Put Event and the procedure (as set out in Section 15.5) for exercising the option contained in this Section 15.2.

The Company shall, forthwith upon becoming aware of the occurrence of the Restructuring Event (a) provide the Trustee with the relevant Directors’ Report and (b) provide or procure that the Reporting Accountants provide the Trustee with the Accountants’ Report. The Directors’ Report and the Accountants’ Report shall, in the absence of manifest error, be conclusive and binding on all concerned, including the Trustee and the Holders. The Trustee shall be entitled to act, or not act, and rely on without being expected to verify the accuracy of the same (and shall have no liability to Holders for doing so) any Directors’ Report and/or any Accountants’ Report (whether or not addressed to it).

69

Section 15.3 Definitions related to Redemption of Securities issued by the Company at the Option of Holders.

The Company shall use reasonable efforts to procure that there shall at the relevant time be Reporting Accountants who have (a) entered into an engagement letter with the Company which shall (i) not limit the liability of the Reporting Accountants by reference to a monetary cap and (ii) be available for inspection by Holders at the principal office of the Trustee or (b) agreed to provide Accountants’ Reports on such other terms as the Company shall approve. If the Company, having used reasonable efforts, is unable to procure that there shall at the relevant time be Reporting Accountants who have entered into an engagement letter complying with (i) above, the Trustee may rely on an Accountants’ Report which contains a limit on the liability of the Reporting Accountants by reference to a monetary cap or otherwise.

Investors should be aware that the engagement letter may contain a limit on the liability of the Reporting Accountants which may impact on the interests of Holders.

The Company shall give notice to the Trustee of the identity of the Reporting Accountants;

“Consolidated Operating Profit” means the consolidated operating profits on ordinary activities before tax and interest and before taking account of depreciation and amortization of goodwill and regulatory assets (for the avoidance of doubt, exceptional items, as reflected in the Relevant Accounts, shall not be included) of the Company and its subsidiaries (including any share of operating profit of associates and joint ventures) determined in accordance with IFRS by reference to the Relevant Accounts;

70

“Negative Rating Event” shall be deemed to have occurred if either (a) the Company does not, either prior to or not later than 21 days after the relevant Restructuring Event, seek, and thereupon use all reasonable efforts to obtain, a rating of the relevant series of Securities or any other unsecured and unsubordinated debt of the Company having an initial maturity of five years or more (“Rateable Debt”) from a Rating Agency or (b) if the Company does so seek and use such efforts, it is unable, as a result of such Restructuring Event, to obtain such a rating of at least investment grade (BBB- or Baa3 or their respective equivalents for the time being), provided that a Negative Rating Event shall not be deemed to have occurred in respect of a particular Restructuring Event if the Rating Agency declining to assign a rating of at least investment grade (as described above) does not announce or publicly confirm that its declining to assign a rating of at least investment grade was the result, in whole or in part, of any event or circumstance comprised in or arising as a result of, or in respect of, the applicable Restructuring Event (whether or not the Restructuring Event shall have occurred at the time such investment grade rating is declined);

“Operating Profit”, in relation to any Disposed Assets, means the operating profits on ordinary activities before tax and interest (for the avoidance of doubt, exceptional items, as reflected in the Relevant Accounts, shall not be included) of the Company and its Subsidiaries directly attributable to such Disposed Assets as determined in accordance with IFRS by reference to the Relevant Accounts and, if Relevant Accounts do not yet exist, determined in a manner consistent with the assumptions upon which the Directors’ Report is to be based. Where the Directors of the Company have employed assumptions in determining the Operating Profit, those assumptions should be clearly stated in the Directors’ Report;

“Rated Securities” means for each series of Securities, the Securities of such series, if and for so long as they shall have an effective rating from a Rating Agency and otherwise any Rateable Debt which is rated by a Rating Agency; provided that if there shall be no such Rateable Debt outstanding prior to the maturity of the Securities, the Holders of not less than one-quarter in principal amount of outstanding Securities of the series may require the Company to obtain and thereafter update on an annual basis a rating of such Securities from a Rating Agency.

“Restructuring Event” shall be deemed to have occurred at any time (whether or not approved by the Board of Directors) that the sum of Disposal Percentages for the Company within any period of consecutive 36 months commencing on or after the initial issue date of the first series of the Securities is greater than 50 percent; and

“Restructuring Period” means the period ending 90 days after a Public Announcement (or such longer period in which the Rated Securities or Rateable Debt, as the case may be, is or are under consideration (announced publicly within the first mentioned period) for rating review or, as the case may be, rating by a Rating Agency).

Section 15.4 Responsibilities of Trustee.

The Trustee shall not be responsible for ascertaining or monitoring whether or not the Restructuring Event, a Negative Rating Event or a Rating Downgrade in relation to the Company has occurred and, unless and until it has actual knowledge to the contrary, shall be entitled to assume that no such event has occurred.

Section 15.5 Procedures for Exercise of Put Option by Holders.

To exercise the option of redemption of a Security under Section 15.2 the Holders must deliver (or cause to be delivered) each Security to be redeemed accompanied by a duly signed and completed notice of exercise in the form (for the time being current) obtainable from the specified office of any Paying Agent (a “Put Notice”), in which the Holders may specify an account to which payment is to be made under this Article XV to the specified office of any Paying Agent on any Business Day falling within the period (the “Put Period”) of 45 days after a Put Event Notice is given. The Security should be delivered after the date (the “Put Date”) falling seven days after the expiry of the Put Period. The Paying Agent to which such Security and Put Notice are delivered will issue to the Holders concerned a nontransferable receipt in respect of the Security so delivered. Payment in respect of any Security so delivered will be made, if the Holder duly specified a bank account in the Put Notice to which payment is to be made, on the Put Date by transfer to that bank account and, in every other case, on or after the Put Date in the same manner as payment for the principal of any premium and interest on the Securities. A Put Notice, once given, shall be irrevocable and no Security so deposited may be withdrawn without the prior consent of the Company. The Company shall redeem the relevant Securities on the Put Date unless previously redeemed or purchased.

Such Securities shall be received and credited for such purpose by the Trustee at the Redemption Price specified in such Securities for redemption through operation of the mandatory sinking fund and the amount of such mandatory sinking fund payment shall be reduced accordingly.

Section 16.3 Redemption of Securities for Sinking Fund.

Not less than 60 days prior to each sinking fund payment date for any series of Securities, the Company will deliver to the Trustee a certificate signed by any director, the treasurer or any duly authorized assistant treasurer of the Company specifying the amount of the next ensuing sinking fund payment for such series pursuant to the terms of such series, the portion thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if any, which is to be satisfied by delivering and crediting Securities of such series pursuant to Section 15.2 and whether the Company intends to exercise its rights to make a permitted optional sinking fund payment with respect to such series. Such certificate shall be irrevocable and upon its delivery the Company shall be obligated to make the cash payment or payments therein referred to, if any, on or before the next succeeding sinking fund payment date. In the case of the failure of the Company to deliver such certificate (or to deliver the Securities, if any, specified in such certificate within the time period specified in Section 15.2), unless otherwise agreed by the Trustee, the sinking fund payment due on the next succeeding sinking fund payment date for such series shall be paid entirely in cash and shall be sufficient to redeem the principal amount of the Securities of such series subject to a mandatory sinking fund payment without the right to deliver or credit Securities as provided in Section 15.2 and without the right to make any optional sinking fund payment, if any, with respect to such series.

Any sinking fund payment or payments (mandatory or optional) made in cash plus any unused balance of any preceding sinking fund payments made with respect to the Securities of any particular series shall be applied by the Trustee (or by the Company if the Company is acting as its own Paying Agent) on the sinking fund payment date on which such payment is made (or, if such payment is made before a sinking fund payment date, on the sinking fund payment date following the date of such payment) to the redemption of Securities of such series at the Redemption Price specified in such Securities with respect to the sinking fund together with accrued interest, if any, to the applicable Redemption Date. Any sinking fund moneys not so applied or allocated by the Trustee (or by the Company if the Company is acting as its own Paying Agent) to the redemption of Securities shall be added to the next sinking fund payment received by the Trustee (or if the Company is acting as its own Paying Agent, segregated and held in trust as provided in Section 4.3) for such series and, together with such payment (or such amount so segregated) shall be applied in accordance with the provisions of this Section 15.3. Any and all sinking fund moneys with respect to the Securities of any particular series held by the Trustee (or if the Company is acting as its own Paying Agent, segregated and held in trust as provided in Section 4.3) on the last sinking fund payment date with respect to Securities of such series and not held for the payment or redemption of particular Securities of such series shall be applied by the Trustee (or by the Company if the Company is acting as its own Paying Agent), together with other moneys, if necessary, to be deposited (or segregated) sufficient for the purpose, to the payment of the principal of the Securities of such series at Maturity.

73

The Trustee shall select or cause to be selected the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 14.2 and the Company shall cause notice of the redemption thereof to be given in the manner provided in Section 14.2 except that the notice of redemption shall also state that the Securities are being redeemed by operation of the sinking fund and whether the sinking fund payment is mandatory or optional, or both, as the case may be. Such notice having been duly given, the redemption of the Securities shall be made upon the terms and in the manner stated in Section 14.3.

On or before each sinking fund payment date, the Company shall pay to the Trustee (or, if the Company is acting as its own Paying Agent, will segregate and hold in trust as provided in Section 4.3) in cash a sum equal to the principal and any interest accrued to the Redemption Date for Securities or portions thereof to be redeemed on such sinking fund payment date pursuant to this Section 16.3.

Neither the Trustee nor the Company shall redeem any Securities of a series with sinking fund moneys or mail any notice of redemption of Securities of such series by operation of the sinking fund for such series during the continuance of a default in payment of interest, if any, on any Securities of such series or of any Event of Default (other than an Event of Default occurring as a consequence of this paragraph) with respect to the Securities of such series, except that if the notice of redemption shall have been provided in accordance with the provisions hereof, the Trustee (or the Company if the Company is acting as its own Paying Agent) shall redeem such Securities if cash sufficient for that purpose shall be deposited with the Trustee (or segregated by the Company) for that purpose in accordance with the terms of this Article XVI. Except as aforesaid, any moneys in the sinking fund for such series at the time when any such default or Event of Default shall occur and any moneys thereafter paid into such sinking fund shall, during the continuance of such default or Event of Default, be held as security for the payment of the Securities of such series; provided, however, that in case such Event of Default or default shall have been cured or waived as provided herein, such moneys shall thereafter be applied on the next sinking fund payment date for the Securities of such series on which such moneys may be applied pursuant to the provisions of this Section 16.3.
