Anything mailed shall not be deemed to have been given until it is actually received. The Corporation may from time to time notify the Trustee of a change in address or facsimile number which thereafter, until changed by like notice, shall be the address or facsimile number of the Corporation for all purposes of this Indenture.

SECTION 107. Notice to Holders; Waiver. Where this Indenture provides for notice of any event to Holders of Securities by the Corporation or the Trustee, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to each such holder affected by such event, at his address as it appears in the Security Register, not later than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice. In any case where notice to Holders of Securities is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders of Securities. Any notice mailed to a Holder in the manner herein prescribed shall be conclusively deemed to have been received by such Holder, whether or not such Holder actually receives such notice.

In case, by reason of the suspension of or irregularities in regular mail service or by reason of any other cause, it shall be impractical to mail notice of any event to Holders of Securities when such notice is required to be given pursuant to any provision of this Indenture, then any manner of giving such notice as shall be satisfactory to the Trustee shall be deemed to be sufficient giving of such notice for every purpose hereunder.

Any request, demand, authorization, direction, notice, consent or waiver required or permitted under this Indenture shall be in the English language.

Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

SECTION 108. Effect of Headings and Table of Contents. The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof.

SECTION 109. Successors and Assigns. All covenants and agreements in this Indenture by the Corporation shall bind its successors and assigns, whether so expressed or not.

SECTION 110. Separability Clause. In case any provision in this Indenture or in any Security shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

SECTION 111. Benefits of Indenture. Nothing in this Indenture or in the Securities, express or implied, shall give to any Person, other than the parties hereto, any Authenticating Agent, any Paying Agent, any Securities Registrar and their successors hereunder and the Holders of Securities, any benefit or any legal or equitable right, remedy or claim under this Indenture.

14

SECTION 112. Governing Law. This Indenture and the Securities shall be governed by and construed in accordance with the law of the State of New York.

SECTION 113. Trust Indenture Act Controls. Each of the Corporation and the Trustee agrees to comply with the provisions of the Trust Indenture Act, to the extent applicable, in connection with this Indenture and any action to be taken hereunder. If and to the extent that any provision of this Indenture limits, qualifies or conflicts with any mandatory requirement of the Trust Indenture Act, such mandatory requirement shall prevail, and all such mandatory requirements of the Trust Indenture Act are incorporated by reference in and made a part of this Indenture.

SECTION 114. Conversion of Currency. The Corporation covenants and agrees that the following provisions shall apply to conversion of currency in the case of the Securities and this Indenture:

(a) (i) If for the purposes of obtaining judgment in, or enforcing the judgment of, any court in any country, it becomes necessary to convert into any other currency (the “Judgment Currency”) an amount due or contingently due under the Securities of any series and this Indenture (the “Required Currency”), then the conversion shall be made at the rate of exchange prevailing on the Business Day before the day on which the judgment is given or the order of enforcement is made, as the case may be (unless a court shall otherwise determine).

(ii) If there is a change in the rate of exchange prevailing between the Business Day before the day on which the judgment is given or an order of endorsement is made, as the case may be (or such other date as a court shall determine), and the date of receipt of the amount due, the Corporation shall pay such additional (or, as the case may be, such lesser) amount, if any, as may be necessary so that the amount paid in the judgment currency when converted at the rate of exchange prevailing on the date of receipt will produce the amount in the Required Currency originally due.

(b) In the event of the winding-up of the Corporation at any time while any amount or damages owing under the Securities and this Indenture, or any judgment or order rendered in respect thereof, shall remain outstanding, the Corporation shall indemnify and hold the Holders of Securities and the Trustee harmless against any deficiency arising or resulting from any variation in rates of exchange between (1) the date as of which the equivalent of the amount in the Required Currency (other than under this Subsection (b)) is calculated for the purposes of such winding-up and (2) the final date for the filing of proofs of claim in such winding-up. For the purpose of this Subsection (b) the final date for the filing of proofs of claim in the winding-up of the Corporation shall be the date fixed by the liquidator or otherwise in accordance with the relevant provisions of applicable law as being the latest practicable date as at which liabilities of the Corporation may be ascertained for such winding-up prior to payment by the liquidator or otherwise in respect thereto.

15

(c) The obligations contained in Subsections (a)(ii) and (b) of this Section shall constitute separate and independent obligations of the Corporation from its other obligations under the Securities and this Indenture, shall give rise to separate and independent causes of action against the Corporation, shall apply irrespective of any waiver or extension granted by any Holder or Trustee from time to time and shall continue in full force and effect notwithstanding any judgment or order or the filing of any proof of claim in the winding-up of the Corporation for a liquidated sum in respect of amounts due hereunder (other than under Subsection (b) above) or under any such judgment or order. Any such deficiency as aforesaid shall be deemed to constitute a loss suffered by the Holders or the Trustee, as the case may be, and no proof or evidence of any actual loss shall be required by the Corporation or its liquidator. In the case of Subsection (b) above, the amount of such deficiency shall not be deemed to be reduced by any variation in rates of exchange occurring between the said final date and the date of any liquidating distribution.

(d) The term “ rate(s) of exchange ” shall mean the rate of exchange quoted by such bank as may be designated in writing by the Corporation to the Trustee from time to time, at its central foreign exchange desk in its main office at 12:00 noon local time on the relevant date for purchases of the Required Currency with the Judgment Currency and includes any premiums and costs of exchange payable.

SECTION 115. Currency Equivalent. Except as otherwise provided in this Indenture, for purposes of the construction of the terms of this Indenture or of the Securities, in the event that any amount is stated herein in the currency of one nation (the “First Currency”), as of any date such amount shall also be deemed to represent the amount in the currency of any other relevant nation (the “Other Currency”) which is required to purchase such amount in the First Currency at the rate of exchange quoted by such bank as may be designated in writing by the Corporation to the Trustee from time to time, at its central foreign exchange desk in its main office in at 12:00 noon local time on the date of determination.

SECTION 116. No Recourse Against Others. A director, officer, employee or shareholder, as such, of the Corporation shall not have any liability for any obligations of the Corporation under the Securities or this Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Security, each Holder shall waive and release all such liability. Such waiver and release shall be part of the consideration for the issue of the Securities.

SECTION 117. Multiple Originals. The parties may sign any number of copies of this Indenture. Each signed copy shall be an original, but all of them together represent the same agreement. One signed copy is enough to prove this Indenture.

SECTION 118. Legal Holidays. In any case where any Interest Payment Date, Redemption Date, sinking fund payment date or Stated Maturity or Maturity of any Security shall not be a Business Day at any Place of Payment, then (notwithstanding any other provision of this Indenture or of any Security other than a provision in the Securities of any series which specifically states that such provision shall apply in lieu of this Section) payment of interest or principal (and premium, if any) need not be made at such Place of Payment on such date, but

16

may be made on the next succeeding Business Day at such Place of Payment with the same force and effect as if made on the Interest Payment Date or Redemption Date or sinking fund payment date, or at the Stated Maturity or Maturity; provided that no interest shall accrue for the period from and after such Interest Payment Date, Redemption Date, sinking fund payment date, Stated Maturity or Maturity, as the case may be.

SECTION 119. CUSIP Numbers, ISINs, etc. The Corporation in issuing the Securities may use “CUSIP” numbers, ISINs and “Common Code” numbers (in each case if then generally in use) and, if so, the Trustee shall use “CUSIP” numbers, ISINs and “Common Code” numbers in notices of redemption as a convenience to Holders; provided, however , that 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 Corporation shall advise the Trustee in writing of any change in any “CUSIP” numbers, ISINs or “Common Code” numbers applicable to the Securities.

ARTICLE TWO

Any endorsement of a Security in global form to reflect the amount, or any increase or decrease in the amount, of Outstanding Securities represented thereby shall be made by the Trustee in such manner and upon instructions given by such Person or Persons as shall be specified therein or in the Corporation Order to be delivered to the Trustee pursuant to Section 303 or Section 304. Subject to the provisions of Section 303 and, if applicable, Section 304, the Trustee shall deliver and redeliver any Security in permanent global form in the manner and upon instructions given by the Person or Persons specified therein or in the applicable Corporation Order.

The provisions of the last sentence of Section 303 shall apply to any Security represented by a Security in global form if such Security was never issued and sold by the Corporation and the Corporation delivers to the Trustee the Security in global form together with an Officers’ Certificate (which need not comply with Section 103 and need not be accompanied by an Opinion of Counsel) with regard to the reduction in the principal amount of Securities represented thereby, together with the Officers’ Certificate contemplated by the last sentence of Section 303.

Notwithstanding the provisions of Section 307, unless otherwise specified as contemplated by Section 301, payment of principal of (and premium, if any, on) and interest on any Security in permanent global form shall be made to the Person or Persons specified therein.

With respect to Securities of any series denominated in Dollars, in the absence of any such provisions, the Securities of such series, other than Securities issued in global form (which may be of any denomination), shall be issuable in denominations of $1,000 and any integral multiple thereof.

SECTION 303. Execution, Authentication, Delivery and Dating. The Securities shall be executed on behalf of the Corporation by any two of the Chairman, the Chief Executive Officer, the President, a Vice President, the Secretary, an Assistant Secretary, the Treasurer or an Assistant Treasurer of the Corporation.

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

At any time and from time to time after the execution and delivery of this Indenture, the Corporation may deliver Securities of any series executed by the Corporation to the Trustee for authentication, together with a Corporation Order for the authentication and delivery of such Securities, and the Trustee in accordance with such Corporation Order shall authenticate and deliver such Securities. If not all the Securities of any series are to be issued at one time and if the Board Resolution or supplemental indenture establishing such series shall so permit, such Corporation Order may set forth procedures acceptable to the Trustee for the issuance of such Securities and determining terms of particular Securities of such series such as interest rate, maturity date, date of issuance and date from which interest shall accrue.

22

In authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall be entitled to receive, and (subject to Section 601) shall be fully protected in relying upon, an Opinion of Counsel stating:

(a) that the form or forms of such Securities have been established in conformity with the provisions of this Indenture;

(b) that the terms of such Securities have been established in conformity with the provisions of this Indenture; and

(c) that such Securities when completed by appropriate insertions and executed and delivered by the Corporation to the Trustee for authentication in accordance with this Indenture, authenticated and delivered by the Trustee in accordance with this Indenture and issued by the Corporation in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute the legal, valid and binding obligations of the Corporation, enforceable in accordance with their terms, subject to applicable bankruptcy, insolvency, reorganization and other similar laws of general application relating to or affecting the enforcement of creditors’ rights, to general equitable principles and to such other qualifications as such counsel shall conclude do not materially affect the rights of Holders of such Securities.

Notwithstanding the provisions of Section 301 and of the preceding two paragraphs, if not all the Securities of any series are to be issued at one time, it shall not be necessary to deliver the Officers’ Certificate otherwise required pursuant to Section 301 or the Corporation Order and Opinion of Counsel otherwise required pursuant to the preceding two paragraphs prior to or at the time of issuance of each Security, but such documents shall be delivered prior to or at the time of issuance of the first Security of such series.

The Trustee shall not be required to authenticate and deliver any such Securities if the issue of such Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner which is not reasonably acceptable to the Trustee.

Each Security shall be dated as of the date of its authentication.

No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for herein duly executed by the Trustee by manual signature of an authorized officer thereof, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture. Notwithstanding the foregoing, if any Security shall have been authenticated and delivered hereunder but never issued and sold by the Corporation, and the Corporation shall deliver such Security to the Trustee for cancellation as provided in Section 310 together with an Officers’ Certificate (which need not comply with Section 103 and need not be accompanied by an Opinion of Counsel) stating that such Security has never been issued and sold by the Corporation, for all purposes of this Indenture such Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture.

23

SECTION 304. Temporary Securities. Pending the preparation of definitive Securities of any series, the Corporation may execute, and upon Corporation Order the Trustee shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued, in registered form, and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as conclusively evidenced by their execution of such Securities. In the case of Securities of any series, such temporary Securities may be in global form.

Except in the case of temporary Securities in global form (which shall be exchanged in accordance with the provisions of the following paragraphs), if temporary Securities of any series are issued, the Corporation will cause definitive Securities of that series to be prepared without unreasonable delay. After the preparation of definitive Securities of such series, the temporary Securities of such series shall be exchangeable for definitive Securities of such series, upon surrender of the temporary Securities of such series at the office or agency of the Corporation in a Place of Payment for that series, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities of any series, the Corporation shall execute and the Trustee shall authenticate and deliver in exchange therefor a like principal amount of definitive Securities of the same series of authorized denominations. 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.

If temporary Securities of any series are issued in global form, any such temporary global Security shall, unless otherwise provided therein, be delivered to the office of a depositary or common depositary (the “Common Depositary”), for credit to the respective accounts of the beneficial owners of such Securities (or to such other accounts as they may direct).

Without unnecessary delay but in any event not later than the date specified in, or determined pursuant to the terms of, any such temporary global Security (the “Exchange Date”), the Corporation shall deliver to the Trustee definitive Securities, in aggregate principal amount equal to the principal amount of such temporary global Security, executed by the Corporation. On or after the Exchange Date such temporary global Security shall be surrendered by the Common Depositary to the Trustee, as the Corporation’s agent for such purpose, to be exchanged, in whole or from time to time in part, for definitive Securities without charge and the Trustee shall authenticate and deliver, in exchange for each portion of such temporary global Security, an equal aggregate principal amount of definitive Securities of the same series of authorized denominations and of like tenor as the portion of such temporary global Security to be exchanged. The definitive Securities to be delivered in exchange for any such temporary global Security shall be in registered form or permanent global registered form, or any combination thereof, as specified as contemplated by Section 301, and, if any combination thereof is so specified, as requested by the beneficial owner thereof.

24

Until exchanged in full as hereinabove provided, the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of the same series and of like tenor authenticated and delivered hereunder.

SECTION 305. Registration, Registration of Transfer and Exchange. The Corporation shall cause to be kept at the corporate trust office of the Trustee a register for each series of Securities (the registers maintained in the corporate trust office of the Trustee and in any other office or agency of the Corporation in a Place of Payment being herein sometimes collectively referred to as the “Security Register”) in which, subject to such reasonable regulations as it may prescribe, the Corporation shall provide for the registration of Securities and of transfers of Securities. The Security Register shall be in written form or any other form capable of being converted into written form within a reasonable time. At all reasonable times, the Security Register shall be open to inspection by the Trustee. The Trustee is hereby initially appointed as security registrar (the “Security Registrar”) for the purpose of registering Securities and transfers of Securities as herein provided.

Upon surrender for registration of transfer of any Security of any series at the office or agency in a Place of Payment for that series, the Corporation shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee, one or more Securities of the same series, of any authorized denominations and of a like aggregate principal amount and tenor.

At the option of the Holder, Securities of any series may be exchanged for other Securities of the same series, of any authorized denomination and of a like aggregate principal amount, upon surrender of the Securities to be exchanged at such office or agency. Whenever any Securities are so surrendered for exchange, the Corporation shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive.

Notwithstanding the foregoing, except as otherwise specified as contemplated by Section 301, any permanent global Security shall be exchangeable only as provided in this paragraph. If any beneficial owner of an interest in the permanent global Security of any series is entitled to exchange such interest for Securities of such series and of like tenor and principal amount of another authorized form and denomination, as specified as contemplated by Section 301 and provided that any applicable notice provided in the permanent global Security shall have been given, then without unnecessary delay but in any event not later than the earliest date on which such interest may be so exchanged, the Corporation shall deliver to the Trustee definitive Securities in aggregate principal amount equal to the principal amount of such beneficial owner’s interest in such permanent global Security, executed by the Corporation. On or after the earliest date on which such interests may be so exchanged, such permanent global Security shall be surrendered by the Common Depositary or such other depositary as shall be specified in the Corporation Order with respect thereto to the Trustee, as the Corporation’s agent for such purpose, to be exchanged, in whole or from time to time in part, for definitive Securities without charge, and the Trustee shall authenticate and deliver, in exchange for each portion of such permanent global Security, an equal aggregate principal amount of definitive Securities of the same series of authorized denominations and of like tenor as the portion of such permanent global Security to be exchanged; provided, however , that no such exchanges may occur during a

25

period beginning at the opening of business 15 days before the day of mailing of a notice of redemption with respect to any Securities and ending on the relevant Redemption Date if the Security for which exchange is requested may be among those selected for redemption. If a Security is issued in exchange for any portion of a permanent global Security after the close of business at the office or agency where such exchange occurs on (i) any Regular Record Date and before the opening of business at such office or agency on the relevant Interest Payment Date, or (ii) any Special Record Date and the opening of business at such office or agency on the related proposed date for payment of Defaulted Interest, interest or Defaulted Interest, as the case may be, will not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of such Security, but will be payable on such Interest Payment Date or proposed date for payment, as the case may be, only to the Person to whom interest in respect of such portion of such permanent global Security is payable in accordance with the provisions of this Indenture.

All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Corporation, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange.

Every Security presented or surrendered for registration of transfer or for exchange shall (if so required by the Corporation or the Security Registrar) be duly endorsed, or be accompanied by a written instrument of transfer, in form satisfactory to the Corporation and the Security Registrar, duly executed by the Holder thereof or his attorney duly authorized in writing.

No service charge shall be made for any registration of transfer or exchange of Securities, but the Corporation 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 304, 306, 1107 or 1305 not involving any transfer.

The Corporation shall not be required (i) to issue, register the transfer of or exchange Securities of any series during a period beginning at the opening of business 15 days before the day of mailing of notice of redemption of Securities of that series under Section 1103 or 1203 and ending at the close of business on the day of the mailing of the relevant notice of redemption, (ii) to register the transfer of or exchange any Security so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part or (iii) to issue, register the transfer of or exchange any Security which has been surrendered for repayment at the option of the Holder, except the portion, if any, of such Security not to be so repaid.

SECTION 306. Mutilated, Destroyed, Lost and Stolen Securities. If any mutilated Security is surrendered to the Trustee, the Corporation shall execute and the Trustee shall authenticate and deliver in exchange therefor a replacement Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding, or, in case any such mutilated Security has become or is about to become due and payable, the Corporation in its discretion may, instead of issuing a new Security, pay such Security.

26

If there shall be delivered to the Corporation and to the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Corporation or the Trustee that such Security has been acquired by a bona fide purchaser, the Corporation shall execute and upon Corporation Order the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a replacement Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding, or, in case any such destroyed, lost or stolen Security has become or is about to become due and payable, the Corporation in its discretion may, instead of issuing a replacement Security, pay such Security.

Upon the issuance of any replacement Security under this Section, the Corporation 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.

Every replacement Security of any series issued pursuant to this Section in lieu of any destroyed, lost or stolen Security shall constitute a contractual obligation of the Corporation, 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 this Indenture equally and proportionately with any and all other Securities of that series duly issued hereunder.

The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities.

SECTION 307. Payment of Interest; Interest Rights Preserved; Optional Interest Reset. (a) Unless otherwise provided as contemplated by Section 301 with respect to any series of Securities, interest on any Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person, in whose name such Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest at the office or agency of the Corporation maintained for such purpose pursuant to Section 1002; provided, however , that each installment of interest on any Security may, at the Corporation’s option, be paid by (i) mailing a check for such interest, payable to or upon the written order of the Person entitled thereto pursuant to Section 309, to the address of such Person as it appears on the Security Register or (ii) wire transfer to an account maintained by the payee located in the United States.

27

Any interest on any Security of any series which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder, and such defaulted interest and, if applicable, interest on such defaulted interest (to the extent lawful) at the rate specified in the Securities of such series (such defaulted interest and, if applicable, interest thereon herein collectively called “Defaulted Interest”) may be paid by the Corporation, at its election in each case, as provided in clause (1) or (2) below:

(1) The Corporation may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Corporation shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security of such series and the date of the proposed payment, and at the same time the Corporation shall deposit with the Trustee an amount of money in the Currency in which the Securities of such series are payable (except as otherwise specified pursuant to Section 301 for the Securities of such series and except, if applicable, as provided in Sections 312(b), 312(d) and 3l2(e)) equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit on or prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Corporation of such Special Record Date and, in the name and at the expense of the Corporation, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be given in the manner provided in Section 107, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so given, such Defaulted Interest shall be paid to the Persons in whose name the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (2).

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

28

(b) The provisions of this Section 307(b) may be made applicable to any series of Securities pursuant to Section 301 (with such modifications, additions or substitutions as may be specified pursuant to such Section 301). The interest rate (or the spread or spread multiplier used to calculate such interest rate, if applicable) on any Security of such series may be reset by the Corporation on the date or dates specified on the face of such Security (each an “ Optional Reset Date ”). The Corporation may exercise such option with respect to such Security by notifying the Trustee of such exercise at least 50 but not more than 60 days prior to an Optional Reset Date for such Security. Not later than 40 days prior to each Optional Reset Date, the Trustee shall transmit, in the manner provided for in Section 107, to the Holder of any such Security a notice (the “Reset Notice”) indicating whether the Corporation has elected to reset the interest rate (or the spread or spread multiplier used to calculate such interest rate, if applicable), and if so (i) such new interest rate (or such new spread or spread multiplier, if applicable) and (ii) the provisions, if any, for redemption during the period from such Optional Reset Date to the next Optional Reset Date or if there is no such next Optional Reset Date, to the Stated Maturity Date of such Security (each such period a “ Subsequent Interest Period ”), including the date or dates on which or the period or periods during which and the price or prices at which such redemption may occur during the Subsequent Interest Period.

Notwithstanding the foregoing, not later than 20 days prior to the Optional Reset Date, the Corporation may, at its option, revoke the interest rate (or the spread or spread multiplier used to calculate such interest rate, if applicable) provided for in the Reset Notice and establish an interest rate (or a spread or spread multiplier used to calculate such interest rate, if applicable) that is higher than the interest rate (or the spread or spread multiplier, if applicable) provided for in the Reset Notice, for the Subsequent Interest Period by causing the Trustee to transmit, in the manner provided for in Section 107, notice of such higher interest rate (or such higher spread or spread multiplier, if applicable) to the Holder of such Security. Such notice shall be irrevocable. All Securities with respect to which the interest rate (or the spread or spread multiplier used to calculate such interest rate, if applicable) is reset on an Optional Reset Date, and with respect to which the Holders of such Securities have not tendered such Securities for repayment (or have validly revoked any such tender) pursuant to the next succeeding paragraph, will bear such higher interest rate (or such higher spread or spread multiplier, if applicable).

The Holder of any such Security will have the option to elect repayment by the Corporation of the principal of such Security on each Optional Reset Date at a price equal to the principal amount thereof plus interest accrued and unpaid to, but not including, such Optional Reset Date. In order to obtain repayment on an Optional Reset Date, the Holder must follow the procedures set forth in Article Thirteen for repayment at the option of Holders except that the period for delivery or notification to the Trustee shall be at least 25 but not more than 35 days prior to such Optional Reset Date and except that, if the Holder has tendered any Security for repayment pursuant to the Reset Notice, the Holder may, by written notice to the Trustee, revoke such tender or repayment until the close of business on the tenth day before such Optional Reset Date.

Subject to the foregoing provisions of this Section and Section 305, 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.

29

SECTION 308. Optional Extension of Stated Maturity. The provisions of this Section 308 may be made applicable to any series of Securities pursuant to Section 301 (with such modifications, additions or substitutions as may be specified pursuant to such Section 301). The Stated Maturity of any Security of such series may be extended at the option of the Corporation for the period or periods specified on the face of such Security (each an “ Extension Period ”) up to but not beyond the date (the “ Final Maturity ”) set forth on the face of such Security. The Corporation may exercise such option with respect to any Security by notifying the Trustee of such exercise at least 50 but not more than 60 days prior to the Stated Maturity of such Security in effect prior to the exercise of such option (the “ Original Stated Maturity ”). If the Corporation exercises such option, the Trustee shall transmit, in the manner provided for in Section 107, to the Holder of such Security not later than 40 days prior to the Original Stated Maturity a notice (the “ Extension Notice ”) indicating (i) the election of the Corporation to extend the Stated Maturity, (ii) the new Stated Maturity, (iii) the interest rate applicable to the Extension Period and (iv) the provisions, if any, for redemption during such Extension Period. Upon the Trustee’s transmittal of the Extension Notice, the Stated Maturity of such Security shall be extended automatically and, except as modified by the Extension Notice and as described in the next paragraph, such Security will have the same terms as prior to the transmittal of such Extension Notice.

Notwithstanding the foregoing, not later than 20 days before the Original Stated Maturity of such Security, the Corporation may, at its option, revoke the interest rate provided for in the Extension Notice and establish a higher interest rate for the Extension Period by causing the Trustee to transmit, in the manner provided for in Section 107, notice of such higher interest rate to the Holder of such Security. Such notice shall be irrevocable. All Securities with respect to which the Stated Maturity is extended will bear such higher interest rate.

If the Corporation extends the Maturity of any Security, the Holder will have the option to elect repayment of such Security by the Corporation on the Original Stated Maturity at a price equal to the principal amount thereof, plus interest accrued and unpaid to, but not including, such date. In order to obtain repayment on the Original Stated Maturity once the Corporation has extended the Maturity thereof, the Holder must follow the procedures set forth in Article Thirteen for repayment at the option of Holders, except that the period for delivery or notification to the Trustee shall be at least 25 but not more than 35 days prior to the Original Stated Maturity and except that, if the Holder has tendered any Security for repayment pursuant to an Extension Notice, the Holder may by written notice to the Trustee revoke such tender for repayment until the close of business on the tenth day before the Original Stated Maturity.

SECTION 309. Persons Deemed Owners. Prior to due presentment of a Security for registration of transfer, the Corporation, the Trustee and any agent of the Corporation or the Trustee may treat the Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of principal of (and premium, if any, on) and (subject to Sections 305 and 307) interest on such Security and for all other purposes whatsoever, whether or not such Security be overdue, and none of the Corporation, the Trustee or any agent of the Corporation or the Trustee shall be affected by notice to the contrary.

None of the Corporation, the Trustee, Paying Agent or the Security Registrar shall have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Security in global form or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

30

Notwithstanding the foregoing, with respect to any global Security, nothing herein shall prevent the Corporation, the Trustee, or any agent of the Corporation or the Trustee, from giving effect to any written certification, proxy or other authorization furnished by any depositary, as a Holder, with respect to such global Security or impair, as between such depositary and owners of beneficial interests in such global Security, the operation of customary practices governing the exercise of the rights of such depositary (or its nominee) as Holder of such global Security.

SECTION 310. Cancellation. All Securities surrendered for payment, redemption, repayment at the option of the Holder, registration of transfer or exchange or for credit against any current or future sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee. All Securities so delivered to the Trustee shall be promptly canceled by it. The Corporation shall deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Corporation may have acquired in any manner whatsoever, and may deliver to the Trustee (or to any other Person for delivery to the Trustee) for cancellation any Securities previously authenticated hereunder which the Corporation has not issued and sold, and all Securities so delivered shall be promptly canceled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section, except as expressly permitted by this Indenture. All canceled Securities held by the Trustee shall be disposed of by the Trustee in accordance with its customary procedures and certification of their disposal delivered to the Corporation unless by Corporation Order the Corporation shall direct that canceled Securities be returned to it.

SECTION 311. Computation of Interest. Except as otherwise specified as contemplated by Section 301 with respect to any Securities, interest on the Securities of each series shall be computed on the basis of a 360-day year consisting of twelve 30-day months.

SECTION 312. Currency and Manner of Payments In Respect of Securities. (a)  Unless otherwise specified with respect to any Securities pursuant to Section 301, with respect to Securities of any series not permitting the election provided for in subsection (b) below or the Holders of which have not made the election provided for in subsection (b) below, except as provided in subsection (d) below, payment of the principal of (and premium, if any, on) and interest, if any, on any Security of such series will be made in the Currency in which such Security is payable. The provisions of this Section 312 may be modified or superseded with respect to any Securities pursuant to Section 301.

(b) It may be provided pursuant to Section 301 with respect to Securities of any series that Holders shall have the option, subject to subsection (d) and (e) below, to receive payments of principal of (and premium, if any, on) or interest, if any, on such Securities in any of the Currencies which may be designated for such election by delivering to the Trustee a written election with signature guarantees and in the applicable form established pursuant to Section 301, not later than the close of business on the Election Date immediately preceding the applicable payment date. If a Holder so elects to receive such payments in any such Currency, such election will remain in effect for such Holder or any transferee of such Holder until changed by such Holder or such transferee by written notice to the Trustee (but any such change must be made not later than the close of business on the Election Date immediately preceding the next

31

payment date to be effective for the payment to be made on such payment date and no such change of election may be made with respect to payments to be made on any Security of such series with respect to which an Event of Default has occurred or with respect to which the Corporation has deposited funds pursuant to Article Four or with respect to which a notice of redemption has been given by the Corporation or a notice of option to elect repayment has been sent by such Holder or such transferee). Any Holder of any such Security who shall not have delivered any such election to the Trustee not later than the close of business on the applicable Election Date will be paid the amount due on the applicable payment date in the relevant Currency as provided in Section 312(a). The Trustee shall notify the Exchange Rate Agent as soon as practicable after the Election Date of the aggregate principal amount of Securities for which Holders have made such written election.

(c) Unless otherwise specified pursuant to Section 301, if the election referred to in subsection (b) above has been provided for pursuant to Section 301, then, unless otherwise specified pursuant to Section 301, not later than the fourth Business Day after the Election Date for each payment date for Securities of any series, the Exchange Rate Agent will deliver to the Corporation a written notice specifying, in the Currency in which Securities of such series are payable, the respective aggregate amounts of principal of (and premium, if any, on) and interest, if any, on the Securities to be paid on such payment date, specifying the amounts in such Currency so payable in respect of the Securities as to which the Holders of Securities of such series shall have elected to be paid in another Currency as provided in subsection (b) above. If the election referred to in paragraph (b) above has been provided for pursuant to Section 301 and if at least one Holder has made such election, then, unless otherwise specified pursuant to Section 301, on the second Business Day preceding such payment date the Corporation will deliver to the Trustee for such series of Securities an Exchange Rate Officer’s Certificate in respect of the Dollar or Foreign Currency payments to be made on such payment date. Unless otherwise specified pursuant to Section 301 the Dollar or Foreign Currency amount receivable by Holders of Securities who have elected payment in a Currency as provided in paragraph (b) above shall be determined by the Corporation on the basis of the applicable Market Exchange Rate in effect on the third Business Day (the “Valuation Date”) immediately preceding each payment date, and such determination shall be conclusive and binding for all purposes, absent manifest error.

(d) If a Conversion Event occurs with respect to a Foreign Currency in which any of the Securities are denominated or payable other than pursuant to an election provided for pursuant to subsection (b) above, then, with respect to each date for the payment of principal of (and premium, if any, on) and interest, if any, on the applicable Securities denominated or payable in such Foreign Currency occurring after the last date on which such Foreign Currency was used (the “Conversion Date”), the Dollar shall be the Currency of payment for use on each such payment date. Unless otherwise specified pursuant to Section 301, the Dollar amount to be paid by the Corporation to the Trustee and by the Trustee or any Paying Agent to the Holders of such Securities with respect to such payment date shall be, in the case of a Foreign Currency other than a currency unit, the Dollar Equivalent of the Foreign Currency or, in the case of a currency unit, the Dollar Equivalent of the Currency Unit, in each case as determined by the Exchange Rate Agent in the manner provided in subsection (f) or (g) below.

32

(e) Unless otherwise specified pursuant to Section 301, if the Holder of a Security denominated in any Currency shall have elected to be paid in another Currency as provided in subsection (b) above, and a Conversion Event occurs with respect to such elected Currency, such Holder shall receive payment in the Currency in which payment would have been made in the absence of such election; and if a Conversion Event occurs with respect to the Currency in which payment would have been made in the absence of such election, such Holder shall receive payment in Dollars as provided in subsection (d) above.

(f) The “Dollar Equivalent of the Foreign Currency” shall be determined by the Exchange Rate Agent and shall be obtained for each subsequent payment date by converting the specified Foreign Currency into Dollars at the Market Exchange Rate on the Conversion Date.

(g) The “Dollar Equivalent of the Currency Unit” shall be determined by the Exchange Rate Agent and, subject to the provisions of subsection (h) below, shall be the sum of each amount obtained by converting the Specified Amount of each Component Currency into Dollars at the Market Exchange Rate for such Component Currency on the Valuation Date with respect to each payment.

(h) For purposes of this Section 312 the following terms shall have the following meanings:

A “ Component Currency ” shall mean any Currency which, on the Conversion Date, was a component currency of the relevant currency unit.

A “ Specified Amount ” of a Component Currency shall mean the number of units of such Component Currency or fractions thereof which were represented in the relevant currency unit on the Conversion Date. If after the Conversion Date the official unit of any Component Currency is altered by way of combination or subdivision, the Specified Amount of such Component Currency shall be divided or multiplied in the same proportion. If after the Conversion Date two or more Component Currencies are consolidated into a single currency, the respective Specified Amounts of such Component Currencies shall be replaced by an amount in such single Currency equal to the sum of the respective Specified Amounts of such consolidated Component Currencies expressed in such single Currency, and such amount shall thereafter be a Specified Amount and such single Currency shall thereafter be a Component Currency. If after the Conversion Date any Component Currency shall be divided into two or more currencies, the Specified Amount of such Component Currency shall be replaced by amounts of such two or more currencies, having an aggregate Dollar Equivalent value at the Market Exchange Rate on the date of such replacement equal to the Dollar Equivalent value of the Specified Amount of such former Component Currency at the Market Exchange Rate immediately before such division and such amounts shall thereafter be Specified Amounts and such currencies shall thereafter be Component Currencies. If, after the Conversion Date of the relevant currency unit, a Conversion Event (other than any event referred to above in this definition of “ Specified Amount ”) occurs with respect to any Component Currency of such currency unit and is continuing on the applicable Valuation Date, the Specified Amount of such Component Currency shall, for purposes of calculating the Dollar Equivalent of the Currency Unit, be converted into Dollars at the Market Exchange Rate in effect on the Conversion Date of such Component Currency.

33

“ Election Date ” shall mean the date for any series of Securities as specified pursuant to clause (13) of Section 301 by which the written election referred to in Subsection (b) above may be made.

All decisions and determinations of the Exchange Rate Agent regarding the Dollar Equivalent of the Foreign Currency, the Dollar Equivalent of the Currency Unit, the Market Exchange Rate and changes in the Specified Amounts as specified above shall be in its sole discretion and shall, in the absence of manifest error, be conclusive for all purposes and irrevocably binding upon the Corporation, the Trustee and all Holders of such Securities denominated or payable in the relevant Currency. The Exchange Rate Agent shall promptly give written notice to the Corporation and the Trustee of any such decision or determination.

In the event that the Corporation determines in good faith that a Conversion Event has occurred with respect to a Foreign Currency, the Corporation will immediately give written notice thereof to the Trustee and to the Exchange Rate Agent (and the Trustee will promptly thereafter give notice in the manner provided for in Section 107 to the affected Holders) specifying the Conversion Date. In the event the Corporation so determines that a Conversion Event has occurred with respect to any currency unit in which Securities are denominated or payable, the Corporation will immediately give written notice thereof to the Trustee and to the Exchange Rate Agent (and the Trustee will promptly thereafter give notice in the manner provided for in Section 107 to the affected Holders) specifying the Conversion Date and the Specified Amount of each Component Currency on the Conversion Date. In the event the Corporation determines in good faith that any subsequent change in any Component Currency as set forth in the definition of Specified Amount above has occurred, the Corporation will similarly give written notice to the Trustee and the Exchange Rate Agent.

The Trustee shall be fully justified and protected in relying and acting upon information received by it from the Corporation and the Exchange Rate Agent and shall not otherwise have any duty or obligation to determine the accuracy or validity of such information independent of the Corporation or the Exchange Rate Agent.

SECTION 313. Appointment and Resignation of Successor Exchange Rate Agent. (a) Unless otherwise specified pursuant to Section 301, if and so long as the Securities of any series (i) are denominated in a Currency other than Dollars or (ii) may be payable in a Currency other than Dollars, or so long as it is required under any other provision of this Indenture, then the Corporation will maintain with respect to each such series of Securities, or as so required, at least one Exchange Rate Agent. The Corporation will cause the Exchange Rate Agent to make the necessary foreign exchange determinations at the time and in the manner specified pursuant to Section 301 for the purpose of determining the applicable rate of exchange.

(b) No resignation of the Exchange Rate Agent and no appointment of a successor Exchange Rate Agent pursuant to this Section shall become effective until the acceptance of appointment by the successor Exchange Rate Agent as evidenced by a written instrument delivered to the Corporation and the Trustee.

34

(c) If the Exchange Rate Agent shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of the Exchange Rate Agent for any cause with respect to the Securities of one or more series, the Corporation, by or pursuant to a Board Resolution, shall promptly appoint a successor Exchange Rate Agent or Exchange Rate Agents with respect to the Securities of that or those series (it being understood that any such successor Exchange Rate Agent may be appointed with respect to the Securities of one or more or all of such series and that, unless otherwise specified pursuant to Section 301, at any time there shall only be one Exchange Rate Agent with respect to the Securities of any particular series that are originally issued by the Corporation on the same date and that are initially denominated and/or payable in the same Currency).

ARTICLE FOUR

If an Event of Default described in clause (1), (2), (3), (4), (5) or (8) of Section 501 with respect to Securities of any series at the time Outstanding occurs and is continuing, then in every such case the Trustee or the Holders of not less than 25% in principal amount of the Outstanding Securities of that series may declare the principal amount (or, if the Securities of that series are Original Issue Discount Securities or Indexed Securities, such portion of the principal amount as may be specified in the terms of that series) of all of the Outstanding Securities of that series and all interest thereon to be due and payable immediately, by a notice in writing to the Corporation (and to the Trustee if given by Holders), and upon any such declaration the same shall become immediately due and payable. If an Event of Default described in clause (6) or (7) of Section 501 with respect to Securities of any series at the time Outstanding occurs and is continuing, the principal amount (or, if the Securities of that series are Original Issue Discount Securities or Indexed Securities, such portion of the principal amount as may be specified in the terms of that series) of all of the Outstanding Securities of that series and all interest thereon shall ipso facto become and be due and payable immediately without any declaration on the part of the Trustee or the Holders of the Outstanding Securities of that series.

If an Event of Default shall have occurred and be continuing the Trustee shall, within 30 days after it becomes aware of the occurrence of such Event of Default, give notice of such Event of Default to the Holders of the Securities of all series then Outstanding affected thereby in the manner provided in Section 107, provided that, notwithstanding the foregoing, except in the case of Events of Default described in clauses (1) and (2) of Section 501, the Trustee shall not be required to give such notice if the Trustee in good faith shall have decided that the withholding of such notice is in the best interests of the Holders of the Outstanding Securities of all series affected thereby and shall have so advised the Corporation in writing. Where a notice of the occurrence of an Event of Default has been given to the Holders of Outstanding Securities of such series pursuant to the preceding sentence and the Event of Default is thereafter cured, the Trustee shall give notice that the Event of Default is no longer continuing to the Holders of Outstanding Securities of such series within 30 days after it becomes aware that the Event of Default has been cured.

At any time after a declaration of acceleration with respect to Securities of any series (or of all series, as the case may be) has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in principal amount of the Outstanding Securities of that series (or of all series, as the case maybe), by written notice to the Corporation and the Trustee, may rescind and annul such declaration and its consequences if:

38

(1) the Corporation has paid or deposited with the Trustee a sum sufficient to pay in the Currency in which the Securities of such series are payable (except as otherwise specified pursuant to Section 301 for the Securities of such series and except, if applicable, as provided in Sections 312(b), 312(d) and 312(e)):

(A) all overdue interest on all Outstanding Securities of that series (or of all series, as the case may be),

(B) all unpaid principal of (and premium, if any, on) any Outstanding Securities of that series (or of all series, as the case may be) which has become due otherwise than by such declaration of acceleration, and interest on such unpaid principal (and premium, if any) at the rate or rates prescribed therefor in such Securities,

(C) interest on overdue interest at the rate or rates prescribed therefor in such Securities, and

(D) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel; and

(2) all Events of Default with respect to Securities of that series (or of all series, as the case may be), other than the non-payment of amounts of principal of (or premium, if any, on) or interest on Securities of that series (or of all series, as the case may be) which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 513.

No such rescission shall affect any subsequent default or impair any right consequent thereon.

Notwithstanding the preceding paragraph, in the event of a declaration of acceleration in respect of the Securities because of an Event of Default specified in Section 501(5) shall have occurred and be continuing, such declaration of acceleration shall be automatically annulled if the Debt that is the subject of such Event of Default has been discharged or the holders thereof have rescinded their declaration of acceleration in respect of such Debt, and written notice of such discharge or rescission, as the case may be, shall have been given to the Trustee by the Corporation and countersigned by the holders of such Debt or a trustee, fiduciary or agent for such holders, within 30 days after such declaration of acceleration in respect of the Securities, and no other Event of Default has occurred during such 30-day period which has not been cured or waived during such period.

39

SECTION 503. Collection of Indebtedness and Suits for Enforcement by the Trustee.

The Corporation covenants that if

(1) default is made in the payment of any installment of interest on any Security when such interest becomes due and payable and such default continues for a period of 30 days, or

(2) default is made in the payment of the principal of (or premium, if any, on) any Security at the Maturity thereof.

then the Corporation will, upon demand of the Trustee, pay to the Trustee for the benefit of the Holders of such Securities, the whole amount then due and payable on such Securities for principal (and premium, if any) and interest, and interest on any overdue principal (and premium, if any) and on any overdue interest, at the rate or rates prescribed therefor in such Securities, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

If the Corporation fails to pay such amounts forthwith upon such demand, the Trustee, in its own name as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Corporation or any other obligor upon such Securities and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Corporation or any other obligor upon such Securities, wherever situated.

If an Event of Default with respect to Securities of any series (or of all series, as the case may be) occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Securities of such series (or of all series, as the case may be) by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy.

SECTION 504. Trustee May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Corporation or any other obligor upon the Securities or the property of the Corporation or of such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Corporation for the payment of overdue principal, premium, if any, or interest) shall be entitled and empowered, by intervention in such proceeding or otherwise,

40

(i) to file and prove a claim for the whole amount of principal (and premium, if any), or such portion of the principal amount of any series of Original Issue Discount Securities or Indexed Securities as may be specified in the terms of such series, and interest owing and unpaid in respect of the Securities and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial proceeding, and

(ii) to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee all amounts due to it hereunder including, without limitation, the costs, charges, expenses, advances and compensation to the Trustee in or about the execution of its trust, or otherwise in relation hereto, with interest thereon as herein provided.

Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

SECTION 505. Trustee May Enforce Claims Without Possession of Securities. Any rights of action and claims under this Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Securities in respect of which such judgment has been recovered.

SECTION 506. Application of Money Collected. Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal (or premium, if any) or interest, upon presentation of the Securities, and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

FIRST, To the payment of all amounts due the Trustee including, without limitations, the costs, charges, expenses, advances and compensation to the Trustee in or about the execution of its trust, or otherwise in relation hereto, with interest thereon as herein provided;

SECOND, To the payment of all amounts due the Holders of the Securities in respect of the costs, charges, expenses, advances incurred in connection with enforcing their rights hereunder;

THIRD, To the payment of the amounts then due and unpaid for principal of (and premium, if any, on) and interest on the Securities in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities for principal (and premium, if any) and interest, respectively; and

41

FOURTH, The balance, if any, to the Person or Persons entitled thereto.

SECTION 507. Limitation on Suits. No Holder of any Outstanding Security of any series shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless:

(1) such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities of that series;

(2) the Holders of not less than 25% in principal amount of the Outstanding Securities of all series affected by such Event of Default (determined as provided in Section 502 and as one class), shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder;

(3) such Holder or Holders have offered to the Trustee reasonable indemnity against the costs, expenses and liabilities to be Incurred in compliance with such request;

(4) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and

(5) no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority or more in principal amount of the Outstanding Securities of all series affected by such Event of Default (determined as provided in Section 502 and as one class);

it being understood and intended that no one or more of such Holders shall have any right in any manner whatsoever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other Holders of the Outstanding Securities of such affected series, or to obtain or to seek to obtain priority or preference over any other of such Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all Holders of the Outstanding Securities of such affected series.

SECTION 508. Unconditional Right of Holders to Receive Principal, Premium and Interest. Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the right, which is absolute and unconditional, to receive payment, as provided herein (including, if applicable, Article Fourteen) and in such Security, of the principal of (and premium, if any, on) and (subject to Section 307) interest on, such Security on the respective Stated Maturities expressed in such Security (or, in the case of redemption, on the Redemption Date) and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder.

42

SECTION 509. Restoration of Rights and Remedies. If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Corporation, the Trustee and the Holders of Securities shall be restored, severally and respectively, to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted.

SECTION 510. Rights and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 306, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders of Securities 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.

SECTION 511. Delay or Omission Not Waiver. No delay or omission of the Trustee or of any Holder of any Security to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

SECTION 512. Control by Holders. The Holders of not less than a majority in principal amount of the Outstanding Securities of all series affected by an Event of Default (determined as provided in Section 502 and as one class) 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 Outstanding Securities of such affected series, provided that in each case

(1) such direction shall not be in conflict with any rule of law or with this Indenture,

(2) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction, and

(3) the Trustee need not take any action which might involve it in personal liability or be unjustly prejudicial to the Holders of Outstanding Securities of such affected series not consenting.

43

SECTION 513. Waiver of Past Defaults. Subject to Section 502, the Holders of not less than a majority in principal amount of the Outstanding Securities of all series with respect to which a Default shall have occurred and be continuing (as one class) may, on behalf of the Holders of all the Outstanding Securities of such affected series, waive any past Default and its consequences, except a Default

(1) in respect of the payment of the principal of (or premium, if any, on) or interest on any Security, or

(2) in respect of a covenant or provision hereof which under Article Nine cannot be modified or amended without the consent of the Holder of each Outstanding Security of such affected series.

Upon any such waiver, any 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 Event of Default or impair any right consequent thereon.

SECTION 514. Waiver of Stay or Extension Laws. The Corporation covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any 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 Corporation (to the extent that it may lawfully do so) hereby expressly waives 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.

SECTION 515. Undertaking for Costs. All parties to this Indenture agree, and each Holder of any Security by 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 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 shall not apply to (i) any suit instituted by the Corporation, (ii) any suit instituted by the Trustee; (iii) any suit instituted by any Holder, or group of Holders, of the Securities of any series holding in the aggregate more than 10% in aggregate principal amount of the Securities of such series, or, in the case of any suit relating to or arising under clause (4) or (8) of Section 501 (if the suit relates to the Securities of more than one but less than all series then Outstanding), 10% in aggregate principal amount of the Securities then Outstanding and affected thereby, or, in the case of any suit relating to or arising under clause (4) or (8) of Section 501 (if the suit relates to all the Securities then Outstanding) or clause (5), (6) or (7) of Section 501, 10% in aggregate principal amount of all Securities then Outstanding or (iv) any suit instituted by any Holder for the enforcement of the payment of the principal of (or premium, if any) or interest on any Security on or after the Stated Maturity or Stated Maturities expressed in such Security or, in the case of redemption, on or after the Redemption Date.

49

Trustee required by Section 611 shall not have been delivered to the Trustee within 90 days after the giving of such notice of resignation, the resigning Trustee may apply to any court of competent jurisdiction for an order for the appointment of a successor Trustee with respect to the Securities of such series.

(3) The Trustee may be removed at any time with respect to the Securities of any series by the Act of the Holders of a majority in aggregate principal amount of the Securities of such series then Outstanding delivered to the Trustee and to the Corporation.

(4) If any time:

(a) the Trustee shall fail to comply with Section 608(1) with respect to the Securities of any series after written request therefor by the Corporation or by any Holder who has been a bona fide Holder of a Security of such series for at least six months; or

(b) the Trustee shall cease to be eligible under Section 609 and shall fail to resign after written request therefor by the Corporation or by any such Holder; or

(c) the Trustee shall be dissolved, shall become incapable of acting or shall become or be adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation;

then, in any such case (i) the Corporation by a Board Resolution may remove the Trustee with respect to the Securities of any or all series, as appropriate, or (ii) subject to Section 610, any Holder who has been a bona fide Holder of a Security of an affected series for at least six months may, on behalf of such Holder and all other Holders similarly situated, apply to any court of competent jurisdiction for an order for the removal of the Trustee and the appointment of a successor Trustee or Trustees.

(5) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of the Trustee for any cause, with respect to the Securities of one or more series, the Corporation, by a Board Resolution, shall promptly appoint a successor Trustee or Trustees with respect to the Securities of such series and shall comply with the applicable requirements of Section 611. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Securities of any series shall be appointed by Act of the Holders of a majority in aggregate principal amount of the Securities of such series then Outstanding delivered to the Corporation and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment in accordance with the applicable requirements of Section 611, become the successor Trustee with respect to the Securities of such series and to that extent supersede the successor Trustee appointed by the Corporation with respect to the Securities of such series. If no successor Trustee with respect to the Securities of any series shall have been so appointed by the

50

Corporation or the Holders and accepted appointment in the manner required by Section 611, any Holder who has been a bona fide Holder of a Security of such series for at least six months may, on behalf of such Holder and all other Holders similarly situated, apply to any court of competent jurisdiction for any order for the appointment of a successor Trustee with respect to the Securities of such series.

(6) The Corporation shall give notice of each resignation and each removal of the Trustee with respect to the Securities of any series and each appointment of a successor Trustee with respect to the Securities of any series to the Holders thereof by mailing such notice to such Holders at their addresses as they shall appear on the Security Register.

Each notice shall include the name of the successor Trustee with respect to the Securities of such series and the address of its Corporate Trust Office.

(1) In case of the appointment hereunder of a successor Trustee with respect to the Securities of one or more series, each successor Trustee so appointed shall execute, acknowledge and deliver to the Corporation and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee with respect to such applicable series of the Securities shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee with respect to such applicable series; but, on the request of the Corporation or the successor Trustee, such retiring Trustee shall, upon payment of its fees and expenses then unpaid, execute, acknowledge and deliver an instrument transferring to such successor Trustee all such rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder.

(2) In case of the appointment hereunder of a successor Trustee with respect to the Securities of one or more (but less than all) series, the Corporation, the retiring Trustee and each successor Trustee with respect to the Securities of one or more series shall execute, acknowledge and deliver an indenture supplemental hereto in which each successor Trustee shall accept such appointment and which shall (i) contain such provisions as shall be deemed necessary or desirable to transfer and confirm to, and to vest in, each successor Trustee all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of each series to which the appointment of such successor Trustee relates, (ii) if the retiring Trustee shall not be retiring with respect to the Securities of all series, contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of the series as to which the retiring Trustee shall not be retiring shall continue to be vested in the retiring Trustee and (iii) add to or change any of the provisions of this Indenture to the extent necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that

51

nothing herein or in such supplemental indenture (except as specifically provided for therein) shall constitute such Trustees co-trustees of the same trust and that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee; and upon the execution and delivery of such supplemental indenture, the resignation or removal of the retiring Trustee shall become effective to the extent provided therein, and each such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of each series to which the appointment of such successor Trustee relates, and such retiring Trustee shall duly assign, transfer and deliver to each successor Trustee all property and money held by such retiring Trustee hereunder with respect to the Securities of each series to which the appointment of such successor Trustee relates.

(3) Upon request of any such successor Trustee, the Corporation shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all rights, powers and trusts referred to subsection (1) or (2) of this Section, as the case may be.

(4) No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article.

SECTION 612. Merger, Consolidation, Amalgamation or Succession to Business. Any corporation into which the Trustee may be merged or with which it may be consolidated or amalgamated, or any corporation resulting from any merger, consolidation or amalgamation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all of the corporate trust business of the Trustee, or any corporation or association to which all or substantially all of the corporate trust business of the Trustee may be sold or otherwise transferred, shall be the successor of the Trustee hereunder without any further act, provided such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or instrument or any further act on the part of any of the parties hereto. In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as though such successor Trustee had itself authenticated such Securities.

SECTION 613. Preferential Collection of Claims Against the Corporation. The Trustee shall comply with TIA § 311(a), excluding any creditor relationship listed in TIA § 311(b). A Trustee who has resigned or been removed shall be subject to TIA § 311(a) to the extent indicated.

SECTION 614. Appointment of Authenticating Agent. The Trustee may appoint an Authenticating Agent or Agents with respect to one or more series of the Securities which shall be authorized to act on behalf of, and subject to the direction of, the Trustee to authenticate the Securities of such series, including Securities issued upon original issue, exchange, registration of transfer or partial redemption thereof or pursuant to Section 306; and Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and

52

obligatory for all purposes as though authenticated by the Trustee. Wherever reference is made in this Indenture to the authentication and delivery of the Securities of any series by the Trustee or to the Trustee’s certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by such Authenticating Agent for such series and a certificate of authentication executed on behalf of the Trustee by such Authenticating Agent. Each Authenticating Agent shall be acceptable to the Corporation and shall at all times be a corporation organized and doing business under the laws of the United States of America, any State thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than $50,000,000 and subject to supervision or examination by Federal or State authority. If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section the combined capital and surplus of such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section.

Any corporation into which an Authenticating Agent may be merged or converted or with which it may be consolidated or amalgamated, or any corporation resulting from any merger, conversion, consolidation or amalgamation to which such Authenticating Agent shall be a party, or any corporation succeeding to all or substantially all of the corporate agency or corporate trust business of any Authenticating Agent, shall be the successor to such Authenticating Agent with respect to all series of the Securities for which it served as Authenticating Agent, provided such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the Trustee or such Authenticating Agent.

Any Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and to the Corporation. The Trustee may at any time terminate the appointment of any Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Corporation. Upon receiving such notice of resignation or upon such termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Corporation and shall, at the expense of the Corporation, provide notice of such appointment to all Holders of the Securities affected thereby in the manner provided in Section 610 with respect to the appointment of a successor Trustee. Any successor Authenticating Agent, upon acceptance of its appointment hereunder, shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as though originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section.

The Corporation agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services hereunder.

SECTION 615. Book-Entry Provisions. In the event that Securities are issued in book-entry form with a securities depositary:

(a) the Trustee may deal with such depositary as the authorized representative of the Holders;

(b) the rights of the Holders shall be exercised only through such depositary and shall be limited to those established by law and agreement between the Holders and such depositary and/or direct participants of such depositary;

(c) such depositary will make book-entry transfers among the direct participants of such depositary and will receive and transmit distributions of principal and interest on the Securities to such direct participants; and

(d) the direct participants of such depositary shall have no rights under this Indenture under or with respect to any of the Securities held on their behalf by such depositary, and such depositary may be treated by the Trustee and its agents, employees, officers and directors as the absolute owner of the Securities for all purposes whatsoever.

SECTION 616. Compensation and Reimbursement. The Corporation agrees:

(a) to pay to the Trustee from time to time reasonable compensation for all services rendered by it 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

(b) except as otherwise expressly provided herein, to reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances Incurred or made by the Trustee in accordance with any provision of this Indenture (including the reasonable compensation and the expenses and disbursements of its agents and counsel), except any such expense, disbursement or advance as may be attributable to its negligence or bad faith.

The Corporation may also from time to time designate one or more other offices or agencies where the Securities of one or more series may be presented or surrendered for any or all such purposes and may from time to time rescind any such designation; provided, however , that no such designation or rescission shall in any manner relieve the Corporation of its obligation to maintain an office or agency in accordance with the requirements set forth above for Securities of any series for such purposes.

The Corporation agrees that it will pay the Trustee reasonable remuneration for its services hereunder and will repay to the Trustee on demand all expenditures or advances whatever which the Trustee may reasonably make or Incur in and about the execution of the trusts hereby created, and such money shall be payable out of any funds coming into the possession of the Trustee in priority to any Securities.

Whenever the Corporation shall have one or more Paying Agents for any series of Securities, it will, prior to or on each due date of the principal of (and premium, if any, on) or interest on any Securities of that series, deposit with a Paying Agent a sum (in the Currency described in the preceding paragraph) sufficient to pay the principal (and premium, if any) or interest so becoming due, such sum to be held in trust for the benefit of the Persons entitled to such principal (and premium, if any) or interest, and (unless such Paying Agent is the Trustee) the Corporation will promptly notify the Trustee of its action or failure so to act.

61

The Corporation will cause each Paying Agent (other than the Trustee) for any series of Securities 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, that such Paying Agent will:

(1) hold all sums held by it for the payment of the principal of (and premium, if any, on) and interest on Securities of such series in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein provided;

(2) give the Trustee notice of any default by the Corporation in the making of any payment of principal of (or premium, if any, on) or interest on the Securities of such series; and

(3) at any time during the continuance of any such default, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent.

The Corporation may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Corporation Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Corporation or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which sums were held by the Corporation 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.

Except as provided in the Securities of any series, any money deposited with the Trustee or any Paying Agent, or then held by the Corporation, in trust for the payment of the principal of (and premium, if any, on) or interest on any Security of any series, and remaining unclaimed for two years after such principal (and premium, if any) or interest has become due and payable shall be paid to the Corporation on Corporation Request, or (if then held by the Corporation) shall be discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the Corporation for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Corporation as trustee thereof, shall thereupon cease.

SECTION 1004. Statement as to Compliance. The Corporation will deliver to the Trustee, within 120 days after the end of each fiscal year, a brief certificate from the principal executive officer, principal financial officer or principal accounting officer as to his or her knowledge of the Corporation’s compliance with all conditions and covenants under this Indenture.

SECTION 1006. Limitation on Liens. The Corporation shall not, and shall not permit any Subsidiary of the Corporation to, Incur any Debt if such Debt is secured by a Lien upon any Principal Property, without in any such case effectively providing that the Securities shall be secured equally and ratably with (or prior to) such Debt; provided, however , that the foregoing restrictions shall not apply to: (a) Liens existing on the date the Securities are originally issued or Liens provided for under the terms of agreements existing on such date; (b) Liens on any property acquired or constructed by the Corporation or any Subsidiary of the Corporation after the date of this Indenture that are created or assumed contemporaneously with or within 270 days after such acquisition or construction to secure or provide for the payment of all or part of the purchase price or cost of construction thereof (or to secure any Debt Incurred by the Corporation or a Subsidiary of the Corporation for the purpose of financing all or a part of the purchase price or cost of construction thereof or of improvements thereon); (c) existing Liens on property acquired (including Liens on any property acquired from a Person that is consolidated or amalgamated with or merged with or into the Corporation or a Subsidiary of the Corporation) or Liens outstanding at the time any Person becomes a Subsidiary of the Corporation that are not Incurred in connection with such entity becoming a Subsidiary of the Corporation; (d) Liens in favor of the Corporation or any Subsidiary of the Corporation; (e) Liens on any property in favor of domestic or foreign governmental bodies to secure partial, progress, advance or other payments pursuant to any contract or statute; (f) Liens on any property to secure asset retirement, reclamation or similar obligations, or to secure penalties, assessments, clean-up costs or other governmental charges relating to environmental protection matters; (g) any extension, renewal or replacement (or successive extensions, renewals or replacements), in whole or in part, of any Lien referred to in any foregoing clause (a), (b), (c), (d), (e) or (f) to the extent that the principal amount of Debt secured thereby does not exceed the principal amount of Debt so secured at the time of such extension, renewal or replacement, together with the reasonable costs (including any premiums or make-whole payments) related to such extension, renewal or replacement, and that such extension, renewal or replacement shall be limited to all or a part of the property that secured the Lien so extended, renewed or replaced (plus improvements on such property); and (h) any Lien which would otherwise be subject to the foregoing restrictions, to the extent that the aggregate principal amount of the Debt so secured, together with the aggregate principal amount of other Debt secured by Liens then outstanding (excluding Debt secured by Liens permitted under the foregoing exceptions and any obligation existing on the date the Securities are originally issued that becomes Debt after such date solely due to a change in U.S. generally accepted accounting principles) and the Attributable Debt in respect of all Sale/Leaseback Transactions entered into after the date of this Indenture (not including Attributable Debt in respect of any such Sale/Leaseback Transactions the proceeds of which are applied to the prepayment of outstanding Securities or other Debt of the Corporation as set forth below under paragraph (3) of Section 1007) would not then exceed 15% of Consolidated Net Tangible Assets.

63

SECTION 1007. Limitation on Sale/Leaseback Transactions. The Corporation shall not, and shall not permit any Subsidiary of the Corporation to, enter into any Sale/Leaseback Transaction with any Person (other than the Corporation or a Subsidiary of the Corporation) unless:

(1) at the time of entering into such Sale/Leaseback Transaction, the Corporation or such Subsidiary would be entitled to Incur Debt, in a principal amount equal to the Attributable Debt with respect to such Sale/Leaseback Transaction, secured by a Lien on such Principal Property subject to such Sale/Leaseback Transaction, pursuant to Section 1006 without equally and ratably securing the Securities pursuant to such provisions;

(2) after the date on which Securities are first issued and within a period commencing six months prior to the consummation of such Sale/Leaseback Transaction and ending six months after the consummation thereof, the Corporation or any Subsidiary shall have expended for property used or to be used in the ordinary course of business of the Corporation or any Subsidiary (including amounts expended for additions, expansions, alterations, repairs and improvements thereto) an amount equal to all or a portion of the net proceeds of such Sale/Leaseback Transaction, and the Corporation shall have elected to designate such amount as a credit against such Sale/Leaseback Transaction (with any portion of such amount not being so designated to be applied as set forth in clause (3) below except to the extent permitted under clause (1) above); or

(3) during the 12-month period after the effective date of such Sale/Leaseback Transaction, the Corporation shall have applied to the voluntary defeasance or retirement of Securities or any Debt of the Corporation (other than Securities or Debt that is held by the Corporation or any Subsidiary of the Corporation or Debt of the Corporation that is subordinate in right of payment to the Securities) an amount equal to the net proceeds of the sale or transfer of the property leased in such Sale/Leaseback Transaction, which amount shall not be less than the fair value of such property at the time of entering into such Sale/Leaseback Transaction (adjusted to reflect any amount expended by the Corporation as set forth in clause (2) above), less an amount equal to the principal amount of such Securities and Debt voluntarily defeased or retired by the Corporation within such 12-month period and not designated as a credit against any other Sale/Leaseback Transaction entered into by the Corporation or any Subsidiary of the Corporation during such period.

SECTION 1008. Waiver of Certain Covenants. The Corporation may, with respect to any series of Securities, omit in any particular instance to comply with any term, provision or condition which affects such series set forth in Section 803 or Sections 1005 to 1007, inclusive, if the Holders of at least a majority in principal amount of all Outstanding Securities of all series affected by such noncompliance (as one class), by Act of such Holders, waive such compliance in such instance 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 Corporation and the duties of the Trustee to Holders of Securities of such series in respect of any such term, provision or condition shall remain in full force and effect.

SECTION 1102. Election to Redeem; Notice to Trustee. The election of the Corporation to redeem any Securities shall be evidenced by or pursuant to a Board Resolution. In case of any redemption at the election of the Corporation, the Corporation shall, at least 60 days prior to the Redemption Date fixed by the Corporation (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of such Redemption Date and of the principal amount of Securities of such series to be redeemed and shall deliver to the Trustee such documentation and records as shall enable the Trustee to select the Securities to be redeemed pursuant to Section 1103. In the case of any redemption of Securities prior to the expiration of any restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture, the Corporation shall furnish the Trustee with an Officers’ Certificate evidencing compliance with such restriction.

SECTION 1103. Selection by Trustee of Securities to Be Redeemed. If less than all the Securities of any series are to be redeemed, the particular Securities to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee, from the Outstanding Securities of such series not previously called for redemption, by such method as the Trustee shall deem fair and appropriate and which may provide for the selection for redemption of portions of the principal of Securities of such series; provided, however , that no such partial redemption shall reduce the portion of the principal amount of a Security not redeemed to less than the minimum authorized denomination for Securities of such series established pursuant to Section 301.

The Trustee shall promptly notify the Corporation 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.

For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the case of any Security redeemed or to be redeemed only in part, to the portion of the principal amount of such Security which has been or is to be redeemed.

SECTION 1104. Notice of Redemption. Except as otherwise specified as contemplated by Section 301, notice of redemption shall be given in the manner provided for in Section 107 not less than 30 nor more than 60 days prior to the Redemption Date, to each Holder of Securities to be redeemed.

65

All notices of redemption shall state:

(1) the Redemption Date,

(2) the Redemption Price,

(3) if less than all the Outstanding Securities of any series are to be redeemed, the identification (and, in the case of partial redemption, the principal amounts) of the particular Securities to be redeemed,

(4) that on the Redemption Date the Redemption Price (together with accrued and unpaid interest, if any, to, but not including, the Redemption Date payable as provided in Section 1106) will become due and payable upon each such Security, or the portion thereof, to be redeemed and, if applicable, that interest thereon will cease to accrue on and after said date,

(5) the place or places where such Securities are to be surrendered for payment of the Redemption Price, and

(6) that the redemption is for a sinking fund, if such is the case.

Notice of redemption of Securities to be redeemed at the election of the Corporation shall be given by the Corporation or, at the Corporation’s request, by the Trustee in the name and at the expense of the Corporation.

SECTION 1105. Deposit of Redemption Price. On or prior to any Redemption Date, the Corporation shall deposit with the Trustee or with a Paying Agent (or, if the Corporation is acting as its own Paying Agent, segregate and hold in trust as provided in Section 1003) an amount of money in the Currency in which the Securities of such series are payable (except as otherwise specified pursuant to Section 301 for the Securities of such series and except, if applicable, as provided in Sections 312(b), 312(d) and 312(e)) sufficient to pay the Redemption Price of, and accrued and unpaid interest on, all the Securities which are to be redeemed on that date.

SECTION 1106. Securities Payable on Redemption Date. Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified in the Currency in which the Securities of such series are payable (except as otherwise specified pursuant to Section 301 for the Securities of such series and except, if applicable, as provided in Sections 312(b), 3l2(d) and 312(e)) (together with accrued and unpaid interest, if any, to, but not including, the Redemption Date), and from and after such date (unless the Corporation shall default in the payment of the Redemption Price and accrued and unpaid interest) such Securities shall, if the same were interest-bearing, cease to bear interest. Upon surrender of any such Security for redemption in accordance with said notice, such Security shall be paid by the Corporation at the Redemption Price, together with accrued and unpaid interest, if any, to, but not including, the Redemption Date; provided , however , that installments of interest on Securities whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Record Dates according to their terms and the provisions of Section 307.

66

If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal (and premium, if any) shall, until paid, bear interest from the Redemption Date at the rate of interest or Yield to Maturity (in the case of Original Issue Discount Securities) set forth in the Security.

SECTION 1107. Securities Redeemed in Part. Any Security which is to be redeemed only in part (pursuant to the provisions of this Article or of Article Twelve) shall be surrendered at a Place of Payment therefor (with, if the Corporation or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Corporation and the Trustee duly executed by, the Holder thereof or such Holder’s attorney duly authorized in writing), and the Corporation shall execute, and the Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new Security or Securities of the same series, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered.

ARTICLE TWELVE

Sinking Funds

SECTION 1201. Applicability of Article. Retirements of Securities of any series pursuant to any sinking fund shall be made in accordance with the terms of such Securities and (except as otherwise specified as contemplated by Section 301 for Securities of any series) in accordance with this Article.

The minimum amount of any sinking fund payment provided for by the terms of Securities of any series is herein referred to as a “mandatory sinking fund payment”, and any payment in excess of such minimum amount provided for by the terms of Securities of any series is herein referred to as an “optional sinking fund payment”. If provided for by the terms of Securities of any series, the cash amount of any mandatory sinking fund payment may be subject to reduction as provided in Section 1202. Each sinking fund payment shall be applied to the redemption of Securities of any series as provided for by the terms of Securities of such series.

SECTION 1202. Satisfaction of Sinking Fund Payments with Securities. Subject to Section 1203, in lieu of making all or any part of any mandatory sinking fund payment with respect to any Securities of a series in cash, the Corporation may at its option (1) deliver to the Trustee Outstanding Securities of a series (other than any previously called for redemption) theretofore purchased or otherwise acquired by the Corporation and/or (2) receive credit for the principal amount of Securities of such series which have been previously delivered to the Trustee by the Corporation or for Securities of such series which have been redeemed either at the election of the Corporation pursuant to the terms of such Securities or through the application of permitted optional sinking fund payments pursuant to the terms of such Securities, in each case in satisfaction of all or any part of any mandatory sinking fund payment with respect to the Securities of the same series required to be made pursuant to the terms of such Securities as provided for by the terms of such series; provided , however , that such Securities have not been previously so credited. 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 sinking fund and the amount of such mandatory sinking fund payment shall be reduced accordingly.

67

SECTION 1203. Redemption of Securities for Sinking Fund. Not less than 60 days prior to each sinking fund payment date for any series of Securities, the Corporation will deliver to the Trustee an Officers’ Certificate specifying the amount of the next ensuing sinking fund payment for that series pursuant to the terms of that series, the portion thereof, if any, which is to be satisfied by payment of cash in the Currency in which the Securities of such series are payable (except as otherwise specified pursuant to Section 301 for the Securities of such series and except, if applicable, as provided in Sections 312(b), 312(d) and 312(e)) and the portion thereof, if any, which is to be satisfied by delivering or crediting Securities of that series pursuant to Section 1202 (which Securities will, if not previously delivered, accompany such certificate) and whether the Corporation intends to exercise its right to make a permitted optional sinking fund payment with respect to such series. Such certificate shall be irrevocable and upon its delivery the Corporation 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 Corporation to deliver such certificate, the sinking fund payment due on the next succeeding sinking fund payment date for that series shall be paid entirely in cash and shall be sufficient to redeem the principal amount of such Securities subject to a mandatory sinking fund payment without the option to deliver or credit Securities as provided in Section 1202 and without the right to make any optional sinking fund payment, if any, with respect to such series.

Not more than 60 days before each such sinking fund payment date the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 1103 and cause notice of the redemption thereof to be given in the name of and at the expense of the Corporation in the manner provided in Section 1104. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Sections 1106 and 1107.

Prior to any sinking fund payment date, the Corporation shall pay to the Trustee or a Paying Agent (or, if the Corporation is acting as its own Paying Agent, segregate and hold in trust as provided in Section 1003) in cash a sum equal to any interest that will accrue to the date fixed for redemption of Securities or portions thereof to be redeemed on such sinking fund payment date pursuant to this Section 1203.

Notwithstanding the foregoing, with respect to a sinking fund for any series of Securities, if at any time the amount of cash to be paid into such sinking fund on the next succeeding sinking fund payment date, together with any unused balance of any preceding sinking fund payment or payments for such series, does not exceed in the aggregate $100,000, the Trustee, unless requested by the Corporation, shall not give the next succeeding notice of the redemption of Securities of such series through the operation of the sinking fund. Any such unused balance of moneys deposited in such sinking fund shall be added to the sinking fund payment for such series to be made in cash on the next succeeding sinking fund payment date or, at the request of the Corporation, shall be applied at any time or from time to time to the purchase of Securities of such series, by public or private purchase, in the open market or otherwise, at a purchase price for such Securities (excluding accrued and unpaid interest and brokerage commissions, for which the Trustee or any Paying Agent will be reimbursed by the Corporation) not in excess of the principal amount thereof.

68

ARTICLE THIRTEEN

Repayment at Option of Holders

SECTION 1301. Applicability of Article. Repayment of Securities of any series before their Stated Maturity at the option of Holders thereof shall be made in accordance with the terms of such Securities and (except as otherwise specified as contemplated by Section 301 for Securities of any series) in accordance with this Article.

SECTION 1302. Repayment of Securities. Securities of any series subject to repayment in whole or in part at the option of the Holders thereof will, unless otherwise provided to the terms of such Securities, be repaid at a price equal to the principal amount thereof, together with accrued and unpaid interest, if any, to, but not including, the Repayment Date specified in or pursuant to the terms of such Securities. The Corporation covenants that, on or before the Repayment Date, it will deposit with the Trustee or with a Paying Agent (or, if the Corporation is acting as its own Paying Agent, segregate and hold in trust as provided in Section 1003) an amount of money in the Currency in which the Securities of such series are payable (except as otherwise specified pursuant to Section 301 for the Securities of such series and except, if applicable, as provided in Sections 312(b), 312(d) and 312(e)) sufficient to pay the principal (or, if so provided by the terms of the Securities of any series, a percentage of the principal) of, and (except if the Repayment Date shall be an Interest Payment Date) accrued and unpaid interest on, all the Securities or portions thereof, as the case may be, to be repaid on such date.

SECTION 1303. Exercise of Option. Securities of any series subject to repayment at the option of the Holders thereof will contain an “Option to Elect Repayment” form on the reverse of such Securities. To be repaid at the option of the Holder, any Security so providing for such repayment, with the “Option to Elect Repayment” form on the reverse of such Security duly completed by the Holder (or by the Holder’s attorney duly authorized in writing), must be received by the Corporation at the Place of Payment therefor specified in the terms of such Security (or at such other place or places or which the Corporation shall from time to time notify the Holders of such Securities) not earlier than 45 days nor later than 30 days prior to the Repayment Date. If less than the entire principal amount of such Security is to be repaid in accordance with the terms of such Security, the principal amount of such Security to be repaid, in increments of the minimum denomination for Securities of such series, and the denomination or denominations of the Security or Securities to be issued to the Holder for the portion of the principal amount of such Security surrendered that is not to be repaid, must be specified. The principal amount of any Security providing for repayment at the option of the Holder thereof may not be repaid in part if, following such repayment, the unpaid principal amount of such Security would be less than the minimum authorized denomination of Securities of the series of which such Security to be repaid is a part. Except as otherwise may be provided by the terms of any Security providing for repayment at the option of the Holder thereof, exercise of the repayment option by the Holder shall be irrevocable unless waived by the Corporation.

69

SECTION 1304. When Securities Presented for Repayment Become Due and Payable. If Securities of any series providing for repayment at the option of the Holders thereof shall have been surrendered as provided in this Article and as provided by or pursuant to the terms of such Securities, such Securities or the portions thereof, as the case may be, to be repaid shall become due and payable and shall be paid by the Corporation on the Repayment Date therein specified, and on and after such Repayment Date (unless the Corporation shall default in the payment of such Securities on such Repayment Date) such Securities shall, if the same were interest-bearing, cease to bear interest. Upon surrender of any such Security for repayment in accordance with such provisions, the principal amount of such Security so to be repaid shall be paid by the Corporation, together with accrued and unpaid interest, if any, to, but not including, the Repayment Date; provided , however , that installments of interest, if any, whose Stated Maturity is on or prior to the Repayment Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Record Dates according to their terms and the provisions of Section 307.

If the principal amount of any Security surrendered for repayment shall not be so repaid upon surrender thereof, such principal amount (together with accrued and unpaid interest, if any, to, but not including, such Repayment Date) shall, until paid, bear interest from the Repayment Date at the rate of interest or Yield to Maturity (in the case of Original Issue Discount Securities) set forth in such Security.

SECTION 1305. Securities Repaid in Part. Upon surrender of any Security which is to be repaid in part only, the Corporation shall execute and the Trustee shall authenticate and deliver to the Holder of such Security, without service charge and at the expense of the Corporation, a new Security or Securities of the same series, of any authorized denomination specified by the Holder, in an aggregate principal amount equal to and in exchange for the portion of the principal of such Security so surrendered which is not to be repaid.

ARTICLE FOURTEEN

Defeasance and Covenant Defeasance

SECTION 1401. Corporation’s Option to Effect Defeasance or Covenant Defeasance. Except as otherwise specified as contemplated by Section 301 for Securities of any series, the provisions of this Article Fourteen shall apply to each series of Securities, and the Corporation may, at its option, effect defeasance of the Securities of or within a series under Section 1402, or covenant defeasance of or within a series under Section 1403 in accordance with the terms of such Securities and in accordance with this Article.

SECTION 1402. Defeasance and Discharge. Upon the Corporation’s exercise of the above option applicable to this Section with respect to any Securities of or within a series, the Corporation shall be deemed to have been discharged from its obligations with respect to such Outstanding Securities on the date the conditions set forth in Section 1404 are satisfied (hereinafter, “ defeasance ”). For this purpose, such defeasance means that the Corporation shall be deemed to have paid and discharged the entire indebtedness represented by such Outstanding Securities, which shall thereafter be deemed to be “Outstanding” only for the purposes of

70

Section 1405 and the other Sections of this Indenture referred to in clauses (A), (B) and (C) below, and to have satisfied all its other obligations under such Securities and this Indenture insofar as such Securities are concerned (and the Trustee, at the expense of the Corporation, shall execute proper instruments acknowledging the same), except for the following which shall survive until otherwise terminated or discharged hereunder: (A) the rights of Holders of such Outstanding Securities to receive, solely from the trust fund described in Section 1404 and as more fully set forth in such Section, payments in respect of the principal of (and premium, if any, on) and interest on such Securities when such payments are due, (B) the Corporation’s obligations with respect to such Securities under Sections 304, 305, 306, 705, 1002 and 1003, (C) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (D) this Article Fourteen.

SECTION 1403. Covenant Defeasance. Upon the Corporation’s exercise of the above option applicable to this Section with respect to any Securities of or within a series, the Corporation shall be released from its obligations under Section 803 and Sections 1005 through 1007, and, if specified pursuant to Section 301, its obligations under any other covenant, with respect to such Outstanding Securities on and after the date the conditions set forth in Section 1404 are satisfied (hereinafter, “ covenant defeasance ”), and such Securities shall thereafter be deemed not to be “Outstanding” for the purposes of any direction, waiver, consent or declaration or Act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed “Outstanding” for all other purposes hereunder. For this purpose, such covenant defeasance means that, with respect to such Outstanding Securities, the Corporation may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 501(4) or Section 501(8) or otherwise, as the case may be, but, except as specified above, the remainder of this Indenture and such Securities shall be unaffected thereby.

SECTION 1404. Conditions to Defeasance or Covenant Defeasance. The following shall be the conditions to application of either Section 1402 or Section 1403 to any Outstanding Securities of or within a series:

(1) The Corporation shall irrevocably have deposited or caused to be deposited with the Trustee (or another trustee satisfying the requirements of Section 607 who shall agree to comply with the provisions of this Article Fourteen applicable to it) as trust funds in trust for the purpose of making the following payments, specifically pledged as security for, and dedicated solely to, the benefit of the Holders of such Securities, (A) an amount (in such Currency in which such Securities are then specified as payable at Stated Maturity), or (B) Government Obligations applicable to such Securities (determined on the basis of the Currency in which such Securities are then specified as payable at Stated Maturity) which through the scheduled payment of principal and interest in respect thereof in accordance with their terms will provide, not later than one day before the due date of any payment of principal (including any

71

premium) and interest, if any, under such Securities, money in an amount, or (C) a combination thereof, sufficient, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge, and which shall be applied by the Trustee (or other qualifying trustee) to pay and discharge, (i) the principal of (and premium, if any, on) and interest on such Outstanding Securities on the Stated Maturity (or Redemption Date, if applicable) of such, principal (and premium, if any) or installment or interest and (ii) any mandatory sinking fund payments or analogous payments applicable to such Outstanding Securities on the day on which such payments are due and payable in accordance with the terms of this Indenture and of such Securities; provided that the Trustee shall have been irrevocably instructed to apply such money or the proceeds of such Government Obligations to said payments with respect to such Securities. Before such a deposit, the Corporation may give to the Trustee, in accordance with Section 1102 hereof, a notice of its election to redeem all or any portion of such Outstanding Securities at a future date in accordance with the terms of the Securities of such series and Article Eleven hereof, which notice shall be irrevocable. Such irrevocable redemption notice, if given, shall be given effect in applying the foregoing.

(2) No Default or Event of Default with respect to such Securities shall have occurred and be continuing on the date of such deposit or, insofar as paragraphs (6) and (7) of Section 501 are concerned, at any time during the period ending on the 91st day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until the expiration of such period).

(3) Such defeasance or covenant defeasance shall not result in a breach or violation of, or constitute a default under, this Indenture or any other material agreement or instrument to which the Corporation is a party or by which it is bound.

(5) In the case of an election under Section 1403, the Corporation shall have delivered to the Trustee an Opinion of Counsel in the United States to the effect that the Holders of such Outstanding Securities will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such covenant defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred.

72

(6) The Corporation shall have delivered to the Trustee an Officers’ Certificate stating that the deposit made by the Corporation pursuant to its election under Section 1402 or 1403 was not made by the Corporation with the intent of preferring the Holders over other creditors of the Corporation or with the intent of defeating, hindering, delaying or defrauding creditors of the Corporation or others.

(7) The Corporation has delivered to the Trustee an Opinion of Counsel to the effect that such deposit shall not cause the Trustee or the trust so created to be subject to the Investment Company Act of 1940.

SECTION 1405. Deposited Money and Government Obligations to Be Held in Trust; Other Miscellaneous Provisions. Subject to the provisions of the last paragraph of Section 1003, all money and Government Obligations (or other property as may be provided pursuant to Section 301) (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 1405, the “ Trustee ”) pursuant to Section 1404 in respect of such Outstanding Securities shall be held in trust and applied by the Trustee, in accordance with the provisions of such Securities and this Indenture, to the payment, either directly or through any Paying Agent (including the Corporation acting as its own Paying Agent) as the Trustee may determine, to the Holders of such Securities of all sums due and to become due thereon in respect of principal (and premium, if any) and interest, but such money need not be segregated from other funds except to the extent required by law.

The Indenture also contains provisions permitting the Holders of specified percentages in aggregate principal amount of the Securities at the time Outstanding, on behalf of the Holders of all the Securities, to waive compliance by the Corporation with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences.

The Securities are issuable only in registered form without coupons in denominations of $1,000 and any integral multiples thereof. As provided in the Indenture and subject to certain limitations therein set forth, the Securities are exchangeable for a like aggregate principal amount of Securities of a different authorized denomination, as requested by the Holder surrendering the same.

No service charge shall be made for any registration of transfer or exchange of Securities, but the Corporation may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.
