THE SECURITIES

Section 2.1. Form and Dating . The Securities shall be issued substantially in the form or forms (including global form) of Exhibit A hereto or in such other form or forms as shall be established by or pursuant to a Board Resolution or Resolutions or any indenture supplemental hereto, in each case with such appropriate insertions, omissions, substitutions or other variations as are required or permitted by this Indenture. The Securities may have notations, legends or endorsements required by law, stock exchange rule or usage. Each Security shall be dated the date of its authentication. Unless otherwise specified in a Board Resolution or Resolutions or supplemental indenture establishing the terms of the Securities, the Securities shall initially be issued only in denominations of $2,000 and integral multiples of $1,000 in excess thereof.

Notwithstanding the foregoing, if any Security of a Series is issuable in the form of a Global Security or securities, each such Global Security may provide that it shall represent the aggregate amount of Securities outstanding under the Series from time to time endorsed thereon and also may provide that the aggregate amount of Securities outstanding under the Series represented thereby may from time to time be reduced or increased. Any endorsement of a Global Security to reflect the amount of Securities outstanding under the Series represented thereby shall be made by the Trustee in accordance with the instructions of the Corporation and in such manner as shall be specified on such Global Security. Any instructions by the Corporation with respect to a Global Security, after its initial issuance, shall be in writing but need not comply with Section 10.4.

Before the first delivery of a Security of any Series to the Trustee for authentication, the Corporation shall deliver to the Trustee the following:

(1) the Board Resolution by or pursuant to which the forms and terms of the Security have been approved;

(2) an Officers’ Certificate of the Corporation dated the date of delivery stating that all conditions precedent provided for in this Indenture relating to the authentication and delivery of Securities in that Series have been complied with and directing the Trustee to authenticate and deliver the Securities to or upon written order of the Corporation; and

(3) an Opinion of Counsel stating that all conditions precedent provided for in this Indenture relating to the authentication and delivery of Securities of that Series have been complied with, subject to such qualifications as such counsel shall conclude are customarily included in similar opinions by lawyers experienced in such matters.

6

Notwithstanding the foregoing, if the Corporation shall establish pursuant to Section 2.3 that the Securities of a Series are to be issued in whole or in part in the form of one or more Global Securities, then the Corporation shall execute and the Trustee shall, in accordance with this Section 2.1, Section 2.2 and the authentication order of the Corporation with respect to such Series, authenticate and deliver one or more Global Securities in temporary or permanent form that shall (a) represent and be denominated in an aggregate amount equal to the aggregate principal amount of the Securities of such Series to be represented by one or more Global Securities, (b) be registered in the name of the Depositary for such Global Security or Global Securities or the nominee of such Depositary, (c) be delivered by the Trustee to such Depositary or pursuant to such Depositary’s instruction, and (d) bear a legend substantially to the following effect: “Unless and until it is exchanged in whole or in part for Securities in definitive form, this Security may not be transferred except as a whole by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any nominee to a successor Depositary or a nominee of any successor Depositary.”

Section 2.2. Execution and Authentication . An Officer shall sign the Securities for the Corporation by manual or facsimile signature. Securities shall be dated the date of their authentication.

If an Officer whose signature is on a Security no longer holds that office at the time the Trustee authenticates the Security, the Security shall be valid nevertheless.

A Security shall not be valid until the Trustee manually signs the certificate of authentication on the Security. The signature shall be conclusive evidence that the Security has been authenticated under this Indenture.

Notwithstanding the provisions of Section 2.3 and of the preceding paragraphs, if all Securities of a Series are not to be originally issued at one time (including, for example, a Series constituting a medium-term note program), it shall not be necessary to deliver the Officers’ Certificate otherwise required pursuant to Section 2.1 or the Opinion of Counsel otherwise required pursuant to such preceding paragraphs at or prior to the time of authentication of each Security of such Series if such documents are delivered at or prior to the time of authentication upon original issuance of the first Security of such Series. In such case the Trustee may conclusively rely on the foregoing documents and opinions delivered pursuant to Section 2.1 and Section 2.3, and this Section 2.2, as applicable (unless revoked by superseding comparable documents or opinions), as to the matters set forth therein.

Notwithstanding the foregoing, if any Security shall have been duly 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 2.12 together with a written statement (which need not comply with Section 2.1

7

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.

If any Security of a Series shall be represented by a Global Security, then, for purposes of this Section 2.2 and Section 2.11, the notation of the record owners’ interest therein upon original issuance of such Security shall be deemed to be delivery in connection with the original issuance of each beneficial owner’s interest in such Global Security.

The Trustee’s certificate of authentication on all Securities shall be in substantially the following form:

This is one of the Securities of the Series designated herein and referred to in the within-mentioned Indenture.

If at any time there shall be an authenticating agent appointed with respect to any Series of Securities, then the Trustee’s certificate of authentication to be borne by the Securities of each such Series shall be substantially as follows:

This is one of the Securities referred to in the within-mentioned Indenture.

The Trustee may appoint an authenticating agent acceptable to the Corporation to authenticate Securities. An authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with the Corporation.

Section 2.3. Title, Amount and Terms of Securities . The principal amount of Securities that may be authenticated and delivered and outstanding under this Indenture is not limited. The Securities may be issued in a total principal amount up to that authorized from time to time by or pursuant to relevant Board Resolutions or established in one or more indentures supplemental hereto.

All Securities of any particular Series need not be issued at the same time and, unless otherwise provided, a Series may be reopened, without the consent of the Holders, for issuances of additional Securities of that Series, unless otherwise specified in the relevant Board Resolution or Resolutions or one or more indentures supplemental hereto.

The Trustee need not authenticate the Securities in any Series if their terms impose on the Trustee duties in addition to those imposed on the Trustee by this Indenture. If the Trustee does authenticate any such Securities, the authentication will evidence the Trustee’s agreement to comply with any such additional duties.

Each Depositary for a Global Security in registered form shall, if required, at the time of its designation and at all times while it serves as a Depositary, be a clearing agency registered under the Exchange Act and any other applicable statute or regulation.

Section 2.4. Registrar, Paying Agent and Calculation Agent . The Corporation shall maintain an office or agency where Securities may be presented for registration of transfer or for exchange (“Registrar”) and an office or agency where Securities may be presented for payment (“Paying Agent”). The Registrar shall keep a register of the Securities and of their transfer and exchange. The Corporation may have one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent. The Corporation may change any Paying Agent, Registrar or Calculation Agent without notice to any Holder. There may be separate Registrars, Paying Agents and Calculation Agents for different Series of Securities.

The agreements shall implement the provisions of this Indenture that relate to such Agent. The Corporation shall notify the Trustee of the name and address of any such Agent.

When such default continues, the Trustee may require the Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent shall have no further liability for the money delivered to the Trustee. If the Corporation or a Subsidiary acts as Paying Agent with respect to a Series of Securities, it shall segregate the money for that Series and hold it as a separate trust fund. The Corporation at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon doing so the Paying Agent shall have no further liability for the money delivered to the Trustee.

Section 2.6. Securityholder Lists . For each Series of Securities, the Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Holders of Securities of that Series and shall otherwise comply with TIA § 312(a). If the Trustee is not the Registrar, the Corporation shall furnish or cause to be furnished to the Trustee on or before each Interest Payment Date for each Series of Securities and at such other times as the Trustee may request in writing a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Holders of Securities of that Series.

Where a Security (other than a Global Security except as set forth herein) is presented to the Registrar or a co-registrar with a request to register a transfer, the Registrar shall register the transfer as requested if the requirements of Section 8-401(1) of the New York Uniform Commercial Code are met. Where Securities (other than a Global Security except as set forth herein) of any Series are presented to the Registrar or a co-registrar with a request to exchange them for an equal principal amount of Securities of other denominations of the same Series with identical terms as the Securities exchanged, the Registrar shall make the exchange as requested if the same requirements are met. To permit transfers and exchanges, the Corporation shall execute and the Trustee shall authenticate Securities at the Registrar’s request. 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 stamp or transfer tax or similar governmental charge payable in connection therewith (other than any such stamp or transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Section 2.11 or 3.7 hereto). The Corporation shall not be required to make transfers or exchanges of Securities of any Series for a period of 15 days before a selection of Securities of the same Series to be redeemed or before an interest payment.

Members of, or participants in, the Depositary (“Agent Members”) shall have no rights under this Indenture with respect to any Global Security held on their behalf by the Depositary, or the Trustee as its custodian, or under the Global Security, and the

12

Depositary may be treated by the Corporation, the Trustee and any agent of the Corporation or the Trustee as the Holder and absolute owner of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, 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 the Depositary or impairing, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a Holder of any Security.

If at any time the Depositary notifies the Corporation that it is unwilling or unable to continue as Depositary for some or all of the Global Securities or if at any time the Depositary shall no longer be eligible to so continue under applicable law, the Corporation shall identify a successor Depositary eligible under applicable law with respect to such Global Securities.

Transfers of any Global Security shall be limited to transfers in whole, but not in part, to the Depository, its successors or their respective nominees. Interests of beneficial owners in the Global Security may be transferred or exchanged for definitive Securities in accordance with the rules and procedures of the Depository. In addition, definitive Securities shall be transferred to all beneficial owners in exchange for their beneficial interests in a Global Security if (i) the Depository notifies the Corporation that it is unwilling or unable to continue as Depository for the Global Security or, if at any time, the Depository ceases to be a clearing agency registered under the Exchange Act, and a successor depository is not appointed by the Corporation within 90 days of such notice, (ii) an Event of Default has occurred and is continuing and the Registrar has received a request from the Depository to issue definitive Securities or (iii) the Corporation, in its discretion, at any time determines not to have such Securities represented by one or more Global Securities and the Corporation so notifies the Depositary; provided that in the event definitive Securities of a Series shall be transferred to all beneficial owners as provided above, the Corporation will execute, and the Trustee, upon receipt of an order of the Corporation for the authentication and delivery of definitive Securities of such Series, will authenticate and deliver to each party specified by such Depositary a new Security or Securities of such Series in definitive form, of any authorized denomination as requested by such party in an aggregate principal amount equal to the principal amount of the Global Security or Securities representing such Series in exchange for such parties beneficial interest in the Global Security or Securities.

In connection with any transfer or exchange of a portion of the beneficial interest in any Global Security to beneficial owners pursuant to the preceding paragraph, the Registrar shall (if one or more definitive Securities are to be issued) reflect on its books and records the date and a decrease in the principal amount of the Global Security in an amount equal to the principal amount of the beneficial interest in the Global Security to be transferred, and the Corporation shall execute, and the Trustee shall authenticate and deliver, one or more definitive Securities of like tenor and amount.

In connection with the transfer of an entire Global Security to beneficial owners pursuant to the two paragraphs above, the Global Security shall be deemed to be surrendered to the Trustee for cancellation, and the Corporation shall execute, and the

13

Trustee upon receipt of an order of the Corporation for the authentication and delivery of definitive Securities of such Series shall authenticate and deliver, to each beneficial owner identified by the Depository in exchange for its beneficial interest in the Global Security, an equal aggregate principal amount of definitive Securities of authorized denominations.

To permit registrations of transfers and exchanges, the Corporation shall execute and the Trustee shall authenticate Global Securities and certificated Securities at the Registrar’s request.

No service charge shall be made to a Holder for any registration of transfer or exchange, but the Corporation may require payment of a sum sufficient to cover any stamp or transfer tax or similar governmental charge payable in connection therewith (other than any such stamp or transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Sections 2.11 and 3.7 hereto).

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

The Registrar shall not be required (A) to issue, to register the transfer of or to exchange Securities of either Series during a period beginning at the opening of fifteen (15) days before the day of any selection of Securities of such Series for redemption under Section 3.3 hereof and ending at the close of business on the day of selection, (B) to register the transfer of or to exchange any Security so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part, or (C) to register the transfer of or to exchange a Security between a record date and the next succeeding Interest Payment Date.

Prior to due presentment for the registration of a transfer of any Security, the Trustee, any Agent and the Corporation may deem and treat the Person in whose name any Security is registered as the absolute owner of such Security for the purpose of receiving payment of principal of, premium, if any, and interest on such Securities and for all other purposes, and neither the Trustee, any Agent nor the Corporation shall be affected by notice to the contrary.

The Trustee shall authenticate Global Securities and definitive Securities in accordance with the provisions of Section 2.2 hereof. Except as provided in the second through fourth paragraphs of this Section 2.7, neither the Trustee nor the Registrar shall authenticate or deliver any definitive Security in exchange for a Global Security.

The Holder of any Global Security may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Indenture or the Securities of such Series.

14

Each Global Security shall also bear the following legend on the face thereof:

“Unless and until it is exchanged in whole or in part for securities in definitive form, this security may not be transferred except as a whole by the depository to a nominee of the depository, or by any such nominee of the depository, or by the depository or nominee of such successor depository or any such nominee to a successor depository or a nominee of such successor depository. Unless this certificate is presented by an authorized representative of The Depository Trust Company, a New York corporation (“DTC”), to an issuer or its agent for registration of transfer, exchange or payment, and any certificate issued is registered in the name of Cede & Co. or such other name as is requested by an authorized representative of DTC (and any payment hereon is made to Cede & Co. or to such other entity as is requested by an authorized representative of DTC), any transfer, pledge or other use hereof for value or otherwise by or to any person is wrongful inasmuch as the registered owner hereof, Cede & Co., has an interest herein.

Transfers of this global security shall be limited to transfers in whole, but not in part, to nominees of Cede & Co. or to a successor thereof or such successor’s nominee.”

Neither the Trustee nor the Registrar shall have any obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Security (including any transfers between or among Agent Members or beneficial owners of interests in any Global Security) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof; provided, that the Trustee shall have no duty to require delivery or examine any certificate for any transfer of interest in the same Global Security.

None of the Corporation, the Trustee, the Paying Agent, the Calculation Agent, the Registrar or any co-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 Global Security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

Upon the exchange of the Global Security for Securities in definitive form, such Global Security shall be canceled by the Trustee. Securities issued in exchange for a Global Security pursuant to this Section 2.7 shall be registered in such names and in such authorized denominations as the Depositary for such Global Security, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. The Trustee shall deliver such Securities to the parties in whose names such Securities are so registered.

Section 2.8. Replacement Securities . If the Holder of a Security claims that the Security has been mutilated, destroyed, lost or stolen, the Corporation may issue and the Trustee shall authenticate a replacement Security of the same Series with identical

15

terms as the Securities exchanged. Such holder shall furnish an indemnity bond sufficient in the judgment of the Corporation and the Trustee to protect the Corporation, the Trustee, the Paying Agent, the Registrar and any co-registrar from any loss which any of them may suffer if a Security is replaced. The Corporation and the Trustee may charge for their expenses in replacing a Security.

In case any such mutilated, destroyed, lost or stolen Security has become due and payable, the Corporation in its discretion may, instead of issuing a new Security, pay such Security (without surrender thereof except in the case of a mutilated Security) if the applicant for such payment shall furnish to the Corporation, the Trustee, the Paying Agent, the Calculation Agent, the Registrar and any co-registrar for such Security such security or indemnity as may be required by them to hold each of them harmless, and in case of destruction, loss or theft, evidence satisfactory to the Corporation, the Trustee, the Paying Agent, the Calculation Agent, the Registrar and any co-registrar, and any agent of any of them, of the destruction, loss or theft of such Security and the ownership thereof.

Upon the issuance of any new Security under this Section 2.8, 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 all fees and expenses of the Trustee, the Paying Agent, the Calculation Agent the Registrar and any co-registrar for such Security) connected therewith.

Every new Security of any Series issued pursuant to this Section 2.8 in lieu of any destroyed, lost or stolen Security or in exchange for any mutilated Security, shall constitute an original additional 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 the same Series.

The provisions of this Section 2.8 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.

Section 2.9. Outstanding Securities . Securities outstanding at any time are all Securities authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation and those described in this Section 2.9 as not outstanding. A Security does not cease to be outstanding because the Corporation or an Affiliate of the Corporation holds the Security.

If a Security is replaced pursuant to Section 2.8, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Security is held by a bona fide purchaser.

If the Paying Agent holds on a redemption date or maturity date money sufficient to pay Securities payable on that date, then on and after that date such Securities cease to be outstanding and interest on them ceases to accrue.

16

If a Security is redeemed (or as to which the full redemption price has been deposited with the Trustee on the applicable Redemption Date), the Corporation and the Trustee need not treat the Security as outstanding in determining whether Holders of the required principal amount of Securities have concurred in any direction, waiver or consent.

Section 2.10. Treasury Notes . In determining whether the Holders of the required aggregate principal amount of Securities of any Series have concurred in any direction, waiver or consent, Securities owned by the Corporation or by any Affiliate of the Corporation shall be considered as though not outstanding, except that, for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Securities shown on the register as being so owned shall be so disregarded. Notwithstanding the foregoing, Securities that are to be acquired by the Corporation or an Affiliate of the Corporation pursuant to an exchange offer, tender offer or other agreement shall not be deemed to be owned by such entity until legal title to such Securities passes to such entity.

Section 2.11. Temporary Securities . Until definitive Securities of any Series are ready for delivery or a permanent Global Security or Securities are prepared, as the case may be, the Corporation may prepare and the Trustee shall authenticate temporary Securities or one or more temporary Global Securities, as the case may be, of the same Series in accordance with the terms and conditions of this Indenture. Temporary Securities of any Series shall be substantially in the form of definitive Securities or permanent Global Securities, as the case may be, of the same Series, but may have variations that the Corporation considers appropriate for temporary Securities. Without unreasonable delay, the Corporation shall prepare and the Trustee shall authenticate definitive Securities or a permanent Global Security or Securities, as the case may be, of the same Series in exchange for temporary Securities. Until so exchanged, the temporary Securities of any Series shall be entitled to the same benefits under this Indenture as definitive Securities or permanent Global Securities of such Series.

Section 2.12. Cancellation . The Corporation at any time may deliver Securities to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Securities surrendered to them for transfer, exchange or payment. Upon the Corporation’s request, the Trustee and no one else shall cancel all Securities surrendered for transfer, exchange, payment or cancellation, and shall so certify to the Corporation. The Corporation may not issue new Securities to replace Securities it has paid or delivered to the Trustee for cancellation.

Section 2.13. Defaulted Interest . If the Corporation defaults in a payment of interest on any Securities of any Series, it shall pay the defaulted interest to the persons who are Holders of those Securities on a subsequent special record date. The Corporation shall fix the special record date and payment date at least 15 days before the special record date, the Corporation shall mail to each Holder of Securities of that Series a notice that states the special record date, the payment date and the amount of defaulted interest to be paid. The Corporation may pay defaulted interest in any other lawful manner.

17

Section 2.14. Payment in Currencies . (a) Payment of the principal of and interest, if any, on the Securities shall be made in the currency or currencies specified below:

(1) for Securities of a Series denominated in U.S. dollars, payment shall be made in U.S. dollars; and

(2) for Securities of a Series denominated in a Foreign Currency, payment shall be made in that Foreign Currency unless the Holder of a Security of that Series elects to receive payment in U.S. dollars and such election is permitted by the Board Resolution or Resolutions or indentures supplemental hereto adopted pursuant to Section 2.3 in respect of that Series.

A Holder may make the election referred to in clause (2) above by delivering to the Trustee or Paying Agent, as applicable, for such series of Securities (the “foreign paying agent”) a written notice of election substantially in the form contemplated by the Board Resolution or Resolutions or indentures supplemental hereto adopted pursuant to Section 2.3 or in any other form acceptable to the foreign paying agent. For any payment, a notice of election will not be effective unless it is received by the foreign paying agent not later than the close of business on the applicable record date. An election shall remain in effect until the Holder delivers to the foreign paying agent a written notice specifying a change in the currency in which payment is to be made. No change in currency may be made for payments to be made on Securities of a Series for which notice of redemption has been given pursuant to Article 3 or as to which the Corporation has accomplished a satisfaction, discharge or defeasance pursuant to Section 8.1, 8.2 or 8.8.

(b) The foreign paying agent shall deliver to the Corporation, not later than the fourth Business Day after each record date for payment on Securities of a Series denominated in a Foreign Currency, a written notice specifying, in the currency in which the Securities of that Series are denominated, the aggregate amount of the principal of and interest, if any, on Securities of that Series to be paid on the payment date. If at least one Holder has made the election referred to in clause (2) of paragraph (a) of this Section 2.14, the written notice shall also specify, in each currency elected, the amount of principal of and interest, if any, to be paid in that currency on the payment date.

(c) The amount payable to Holders of Securities of a Series denominated in a Foreign Currency who have elected to receive payment in U.S. dollars shall be determined by the foreign paying agent on the basis of the Market Exchange Rate in effect on the record date.

(d) If the Foreign Currency in which a Series of Securities is denominated ceases to be used both by the government of the country that issued such currency and for the settlement of transactions by public institutions of or within the international banking community, then for each payment date on Securities of that Series occurring after the last date on which the Foreign Currency was so used, all payments on Securities of that Series shall be made in U.S. dollars. If payment is to be made in U.S.

18

dollars to the Holders of Securities of any such Series pursuant to the preceding sentence, then the amount to be paid in U.S. dollars on a payment date by the Corporation to the foreign paying agent and by the foreign paying agent or any Paying Agent to Securityholders shall be determined by the foreign paying agent as of the applicable record date and shall be equal to the sum obtained by converting the specified Foreign Currency into U.S. dollars at the Market Exchange Rate on the last record date on which such Foreign Currency was so used in either such capacity.

(e) All decisions and determinations of the foreign paying agent regarding the amount payable in accordance with paragraph (c) of this Section 2.14, conversion of Foreign Currency into U.S. dollars pursuant to paragraph (d) of this Section 2.14 or the Market Exchange Rate shall, in the absence of manifest error, be conclusive for all purposes and irrevocably binding upon the Corporation and all Securityholders. If a Foreign Currency in which payment on Securities of a Series may be made pursuant to paragraph (a) of this Section 2.14 ceases to be used both by the government of the country that issued such currency and for the settlement of transactions by public institutions of or within the international banking community, the Corporation shall give notice to the foreign paying agent and mail notice by first-class mail to each Holder of Securities of that Series specifying the last date on which the Foreign Currency was used for the payment of principal of or interest, if any, on Securities of that Series.

Section 2.15. CUSIP Numbers . The Corporation in issuing the Securities may use a “CUSIP” and/or ISIN or other similar number, and if it does so, the Corporation may use the CUSIP and/or ISIN or other similar number in notices of redemption or exchange as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness or accuracy of the CUSIP and/or ISIN or other similar number printed in the notice or on the Securities and that reliance may be placed only on the other identification numbers printed on the Securities. The Corporation shall promptly notify the Trustee of any change in the CUSIP and/or ISIN or other similar number.

ARTICLE 3

REDEMPTION

Section 3.1. Applicability of this Article . Securities of any Series that are redeemable prior to their maturity shall be redeemable in accordance with their terms (except as otherwise specified in this Indenture for Securities of any Series) and in accordance with this Article 3.

Section 3.2. Notices to Trustee . If the Corporation chooses to redeem any Securities, it shall notify the Trustee of the redemption date and the principal amount of Securities to be redeemed in accordance with the terms of the Securities. If redemption is of less than all the outstanding Securities of a Series, the Corporation shall furnish to the Trustee, at least 30 days before the optional redemption date (or such shorter period as is acceptable to the Trustee) an Officers’ Certificate stating (i) the aggregate principal amount of Securities to be redeemed and (ii) the redemption date.

19

Section 3.3. Selection of Securities to be Redeemed . If, at the option of the Corporation, less than all the Securities of a Series are to be redeemed, the Trustee shall select the Securities of such Series to be redeemed on a pro rata basis, by lot or by such method as the Trustee shall deem fair and appropriate or in accordance with the applicable procedures of the Depositary. The Trustee shall make the selection from outstanding Securities of such Series not previously called for redemption and shall promptly notify the Corporation in writing of the Securities of such Series selected for redemption and, in the case of any Securities selected for partial redemption, the principal amount thereof to be redeemed. The Trustee may select for redemption portions of the principal of Securities that have a denomination larger than $2,000 (or the applicable minimum denomination for such Securities in the event the Securities are payable in a Foreign Currency or Currencies), Securities and portions of them it selects shall be in minimum amounts of $2,000 (or the applicable minimum denomination for such Securities in the event the Securities are payable in a Foreign Currency or Currencies) or a multiple of $1,000 (or the applicable minimum denomination for such Securities in the event the Securities are payable in a Foreign Currency or Currencies). Provisions of this Indenture that apply to Securities called for redemption also apply to portions of Securities called for redemption.

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 Securities which has been or is to be redeemed.

Section 3.4. Notice of Redemption . At least 15 days but not more than 30 days before a date of redemption of Securities at the option of the Corporation, the Corporation shall send or cause to be sent by electronic transmission or by first class mail (with a copy to the Trustee), a notice of redemption to each Holder of Securities to be redeemed. Notice of any redemption may not be subject to any conditions precedent.

The notice shall identify the Securities to be redeemed and shall state:

(1) the optional redemption date;

(2) the redemption price, including the portion thereof representing any accrued and unpaid interest (or the formula for the determination thereof if the redemption price cannot be determined until a later date);

(3) if any Security is being redeemed in part, the portion of the principal amount of such Securities to be redeemed and that, after the redemption date, upon surrender of such Security, a new Security in principal amount equal to the unredeemed portion shall be issued upon cancellation of the original Security.

(4) the name and address of the Paying Agent;

20

(5) that Securities called for redemption must be surrendered to the Paying Agent to collect the redemption price;

(6) that, unless the Corporation defaults in making such redemption payment, interest on Securities called for redemption ceases to accrue on and after the redemption date;

(7) the paragraph of the Securities and/or Section of this Indenture (or any supplement to this Indenture) pursuant to which the Securities called for redemption are being redeemed; and

(8) that no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Securities called for redemption.

At the Corporation’s request, the Trustee shall give the notice of redemption in the Corporation’s name and at its expense; provided, however that the Corporation notified the Trustee of its intent to have the Trustee give such notice of redemption at least two Business Days prior to date such notice of redemption is given. In such event the Corporation will provide the Trustee with the information required by clauses (1) through (8). The notice sent in the manner herein provided shall be conclusively presumed to have been duly given whether or not a Holder receives such notice. In any case, failure to give such notice by electronic transmission or by mail or any defect in the notice to the Holder of any Security shall not affect the validity of the notice to any other Holder.

Section 3.5. Effect of Notice of Redemption . Once a notice of redemption has been sent in accordance with Section 3.4, the Securities called for redemption become due and payable on the redemption date and at the redemption price in each case stated in the notice. Upon surrender to the Paying Agent, such Securities shall be paid at the redemption price stated in the notice, plus accrued and unpaid interest to the redemption date; provided, however, that any regular payment of interest becoming due on the redemption date shall be payable to the Holder of any such Security being redeemed as provided in the Security.

Section 3.6. Deposit of Redemption Price . On or before 10:00 a.m. (New York City time) on each redemption date, the Corporation shall deposit with the Trustee or with the Paying Agent (other than the Corporation or an Affiliate of the Corporation) money sufficient to pay the applicable redemption price of all Securities to be redeemed on that date. The Trustee or the Paying Agent shall promptly return to the Corporation any money deposited with the Trustee or the Paying Agent by the Corporation in excess of the amounts necessary to pay the redemption price of all Securities to be redeemed.

If Securities called for redemption are paid or if the Corporation has deposited with the Trustee or Paying Agent money sufficient to pay the redemption price of all Securities to be redeemed, on and after the redemption date, interest shall cease to accrue on the Securities or the portions of Securities called for redemption (regardless of

21

whether certificates for such Securities are actually surrendered). If any Security called for redemption shall not be so paid upon surrender for redemption because of the failure of the Corporation to comply with the preceding paragraph, interest shall be paid on the unpaid principal from the redemption date until such principal is paid, and, to the extent lawful, on any interest not paid on such unpaid principal, in each case, at the rate provided in such Security.

Section 3.7. Securities Redeemed in Part . Upon surrender of a Security that is redeemed in part, the Corporation shall issue and, upon the written request of an Officer of the Corporation, the Trustee shall authenticate for the Holder a new Security equal in principal amount to the unredeemed portion of the Security surrendered.

(New York City time) on the date such amounts are due and payable.

Section 4.2. Compliance Certificate . The Corporation shall deliver to the Trustee within 120 days after the end of each fiscal year of the Corporation an Officers’ Certificate stating whether or not the signers know of any Default by the Corporation in performing its covenants in this Indenture. If they do know of such a Default, the certificate shall describe the Default. The certificate need not comply with Section 10.5.

The Corporation shall, so long as any of the Securities are outstanding, deliver to the Trustee, within 30 days after the occurrence thereof, written notice in the form of an Officers’ Certificate of any event which is an Event of Default and what action the Corporation is taking or proposes to take in respect thereof.

Section 4.3. SEC Reports . The Corporation shall file with the Trustee within 15 days after it files them with the SEC copies of the annual reports and of the information, documents and other reports (or copies of such portions of any of the foregoing as the SEC may by rules and regulations prescribe) which the Corporation files with the SEC pursuant to Section 13 or Section 15(d) of the Exchange Act. Delivery of such reports, information and documents to the Trustee pursuant to this Section 4.3 is for informational purposes only, and the Trustee’s receipt thereof shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Corporation’s compliance with any of its covenants under this Indenture (as to which the Trustee is entitled to certificates). Notwithstanding the foregoing, the Corporation will be deemed to have furnished such reports to the Trustee and the Holders if the Corporation has filed such reports with the SEC via the EDGAR filing system (or any successor thereto) and such reports are publicly available.

ARTICLE 6

DEFAULTS AND REMEDIES

Section 6.1. Events of Default . Each of the following constitutes an “Event of Default” in respect of a Series of Securities:

(1) the Corporation defaults in the payment of any interest on any Security of that Series when the same becomes due and payable and the Default continues for a period of 30 days;

23

(2) the Corporation defaults in the payment of the principal of (or in the case of any Discounted Security of that Series, the portion thereby specified in the terms of such Security) or premium, if any, on any Security of that Series when the same becomes due and payable;

(3) the Corporation fails to comply with any of its agreements in the Securities of that Series or this Indenture for the benefit of that Series (other than those referred to in clauses (1) or (2) above) and the Default continues for the period and after the notice specified in this Section 6.1;

(4) the Corporation pursuant to or within the meaning of any Bankruptcy Law:

(A) commences a voluntary case,

(B) consents to the entry of an order for relief against it in an involuntary case,

(C) consents to the appointment of a Custodian of it or for all or substantially all of its property, or

(D) makes a general assignment for the benefit of its creditors;

(5) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that:

(i) is for relief against the Corporation in an involuntary case,

(ii) appoints a Custodian of the Corporation or for all or substantially all of its property, or

(iii) orders the winding up or liquidation of the Corporation, and

the order or decree remains unstayed and in effect for 60 days; or

(6) there occurs any other event specifically described as an Event of Default by the Securities of that Series.

A default under clause (3) shall not be an Event of Default with respect to a Series of Securities until the Trustee or the Holders of at least 25% in principal amount of the then outstanding Securities of such Series issued pursuant to this Indenture (including any additional Securities of such Series issued pursuant to this Indenture after the Issue Date) notify the Corporation in writing of the Default and the Corporation does not cure the Default within 90 days after receipt of the notice. The notice must specify the Default, demand that it be remedied and state that the notice is a “Notice of Default.” Subject to Sections 7.1 and 7.2, the Trustee shall not be charged with actual knowledge of any Default, or of the delivery to the Corporation of a notice of Default by any Holder, unless written notice thereof shall have been given to a Responsible Officer of the Trustee by the Corporation, the Paying Agent, the Holder of a Security or an agent of such Holder.

24

Section 6.2. Acceleration . If an Event of Default in respect of the Securities of a particular Series (other than an Event of Default specified in clause (4) or (5) of Section 6.1) occurs and is continuing, then the Trustee or the Holders of not less than 25% in aggregate principal amount of the then outstanding Securities of such Series issued pursuant to this Indenture (including any additional Securities of such Series issued pursuant to this Indenture after the Issue Date) may declare the principal (or, in the case of Discounted Securities, such amount of principal as may be provided for in such Securities) of all of such outstanding Securities and any accrued interest on such Securities to be due and payable immediately by a notice in writing to the Corporation (and to the Trustee if given by the Holders); provided , however , that if an Event of Default specified in clause (4) or (5) of Section 6.1 occurs and is continuing, then the principal and accrued and unpaid interest on all the Securities of that Series shall become immediately due and payable without any declaration or other act on the part of the Trustee or any Holders; provided further , however , that, except with respect to nonpayment of principal or premium (if any) on the Securities of such Series, Holders of a majority in aggregate principal amount of the then outstanding Securities of a Series issued pursuant to this Indenture (including any additional Securities of such Series issued pursuant to this Indenture after the Issue Date), by notice to the Trustee, may rescind and annul a declaration of acceleration (and upon such rescission any Event of Default caused by such acceleration shall be deemed cured) with respect to that Series and its consequences if all existing Events of Default with respect to the Series have been cured or waived, if the rescission and annulment would not conflict with any judgment or decree of a court of competent jurisdiction obtained by the Trustee for the payment of amounts due on the Securities, and if all payments due to the Trustee under Section 7.7 have been made.

Section 6.3. Other Remedies . If an Event of Default with respect to a Series of Securities occurs and is continuing, the Trustee may pursue any available remedy by proceeding at law or in equity to collect the payment of principal (or, in the case of Discounted Securities, such amount of principal as may be provided for in such Securities), premium, if any, or interest on the Securities of that Series or to enforce the performance of any provision of such Securities or this Indenture.

The Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Securityholder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative to the extent permitted by law.

Section 6.4. Waiver of Past Defaults . Subject to Section 9.2, the Holders of a majority in principal amount of the Securities of a Series (including any additional Securities of such Series issued pursuant to this Indenture after the Issue Date) by notice to the Trustee may waive an existing Default or Event of Default with respect to that

25

Series and its consequences. When a Default or Event of Default is waived, it is cured and stops continuing, but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereto.

Section 6.5. Control by Majority . The Holders of a majority in principal amount of the Securities of a Series may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on it with respect to that Series. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture, or, subject to Section 7.1, that the Trustee determines is unduly prejudicial to the rights of other Holders of Securities of the same Series or would involve the Trustee in personal liability.

Section 6.6. Limitation on Suits . No Holder of a Security of any Series may pursue any remedy with respect to this Indenture or the Securities unless:

(1) the Holder gives to the Trustee written notice stating that an Event of Default with respect to the Securities of the Series is continuing;

(2) the Holders of at least 25% in principal amount of the Securities of that Series (including any additional Securities of such Series issued pursuant to this Indenture after the Issue Date) make a written request to the Trustee to pursue the remedy;

(3) such Holder or Holders offer to the Trustee indemnity satisfactory to the Trustee against any loss, liability or expense;

(4) the Trustee does not comply with the request within 60 days after receipt of the request and the offer of indemnity; and

(5) during such 60-day period the Holders of a majority in principal amount of the Securities of that Series (including any additional Securities of such Series issued pursuant to this Indenture after the Issue Date) do not give the Trustee a direction inconsistent with the request.

A Holder may not use this Indenture to prejudice the rights of another Securityholder or to obtain a preference or priority over another Holder.

Section 6.7. Rights of Holders to Receive Payment . Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal (or, in the case of a Discounted Security, the portion thereby specified in the terms of such Security), premium, if any, and interest on the Security on or after the respective due dates expressed in the Security, or to bring suit for the enforcement of any such payment on or after such respective date, shall not be impaired or affected without the consent of the Holder.

Section 6.8. Collection Suit by Trustee . If an Event of Default in payment of interest or principal specified in Section 6.1(1) or (2) occurs and is continuing with respect to a Series of Securities, the Trustee may recover judgment in its own name and as trustee of an express trust against the Corporation for the whole amount of principal and interest remaining unpaid.

26

Section 6.9. Trustee May File Proofs of Claim . The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee and the Holders allowed in any judicial proceedings relative to the Corporation, or any of its creditors or property, and unless prohibited by law or applicable regulations, may vote on behalf of the Holders in any election of a trustee in bankruptcy or other Person performing similar functions. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.7 hereof out of the estate in any such proceeding shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. 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, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 6.10. Priorities . If the Trustee collects any money pursuant to this Article 6 with respect to the Securities of any Series, it shall pay out the money in the following order:

First: to the Trustee for amounts due under Section 7.7;

Second: to Holders of Securities of that Series for amounts due and unpaid on such Securities for principal, premium, if any, and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities for principal, premium, if any, and interest, respectively; and

Third: to the Corporation.

The Trustee may fix a record date and payment date for any payment to Securityholders pursuant to this Section 6.10.

Section 6.11. Undertaking for Costs . 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 or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit other than the Trustee of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in the suit having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.7 or a suit by Holders of more than 10% in principal amount of the Securities of any Series.

ARTICLE 7

TRUSTEE

Section 7.1. Duties of Trustee .

The Trustee shall be under no obligation to exercise any of its rights and powers under this Indenture at the request or direction of any of the Holders, unless such Holder has offered to the Trustee security or indemnity reasonably satisfactory to it against any loss, liability or expense.

Section 7.3. Individual Rights of Trustee, etc. The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Corporation or any of its Affiliates with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest as defined in TIA § 310(b), it must eliminate such conflict within 90 days, apply to the SEC for permission to continue as Trustee, or resign. Any Agent may do the same with like rights. Notwithstanding the foregoing, the Trustee must comply with Sections 7.10 and 7.11.

Section 7.4. Trustee ’ s Disclaimer . The Trustee makes no representations as to the validity or adequacy of this Indenture or the Securities, it shall not be accountable for the Corporation’s use of the proceeds from the Securities, and it shall not be responsible for any statement in the Securities other than its certificate of authentication.

30

Section 7.5. Notice of Defaults . If an Event of Default occurs with respect to a Series of Securities and is continuing and if it is actually known to the Trustee, the Trustee shall send to each Holder of Securities of that Series notice of the Event of Default within 90 days after it occurs, unless the Event of Default is cured or waived. Except in the case of an Event of Default in payment of principal, premium, if any, or interest on any Security, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers determines in good faith that withholding the notice is in the interests of such Holders.

Section 7.6. Reports by Trustee to Holders of the Securities . If required pursuant to TIA § 313(a), the Trustee, within 60 days after each May 15, shall send to each Securityholder a brief report dated as of such May 15 that complies with TIA § 313(a). The Trustee also shall comply with the reporting obligations of TIA § 313(b).

A copy of each report at the time it is sent to Securityholders shall be filed with the SEC and each stock exchange on which the Securities are listed. The Corporation agrees to notify the Trustee whenever the Securities become listed on any stock exchange.

Section 7.7. Compensation and Indemnity . The Corporation shall pay to the Trustee from time to time reasonable compensation for its services. The Corporation shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses incurred by it. Such expenses shall include the reasonable compensation and expenses of the Trustee’s agents and counsel. The Corporation shall indemnify and hold harmless the Trustee (including the cost of defending itself) against any loss, cost, expense or liability, including taxes (other than taxes based upon, measured by or determined by the income of the Trustee) and including reasonable and documented attorneys’ fees and expenses incurred by it except as set forth in the last sentence of this paragraph in the performance of its duties and exercise of its rights under this Indenture. The Trustee shall notify the Corporation promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Corporation shall not relieve the Corporation of its obligations hereunder except to the extent that the Corporation has been materially prejudiced thereby. The Corporation need not pay for any settlement made without its consent (not to be unreasonably withheld). This indemnification shall apply to officers, directors, employees, shareholders and agents of the Trustee. The Corporation need not reimburse any expense or indemnify against any loss or liability incurred by the Trustee or by any officer, director, employee, shareholder or agent of the Trustee through willful misconduct or negligence.

To secure the Corporation’s payment obligations in this Section 7.7, the Trustee shall have a senior claim to which the Securities are hereby made subordinate on all money or property held or collected by the Trustee, except that held in trust to pay principal, premium, if any, of and interest on particular Securities.

31

When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.1(4) or (5) occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any Bankruptcy Law.

The obligations of the Corporation under this Section 7.7 shall survive the termination of this Indenture and the resignation or removal of the Trustee.

Section 7.8. Replacement of Trustee . The Trustee may resign with respect to the Securities of one or more Series by so notifying the Corporation. The Holders of a majority in principal amount of the then outstanding Securities of a Series issued pursuant to this Indenture (including any additional Securities issued pursuant to this Indenture after the Issue Date) may remove the Trustee with respect to that Series by so notifying the removed Trustee and may appoint a successor Trustee with the Corporation’s consent. The Corporation may remove the Trustee if:

(1) the Trustee fails to comply with Section 7.10;

(2) the Trustee is adjudged bankrupt or insolvent;

(3) a receiver or other public officer takes charge of the Trustee or its property; or

(4) the Trustee otherwise becomes incapable of acting.

If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Corporation shall promptly appoint a successor Trustee.

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Corporation. Immediately thereafter, the retiring Trustee shall transfer all property held by it as Trustee for the benefit of the Series with respect to which it is retiring to the successor Trustee, and the resignation or removal of the retiring Trustee shall then become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture with respect to that Series. A successor Trustee shall send notice of its succession to each Holder of the Securities of the Series affected.

If pursuant to Section 2.3(5) a trustee, other than the Trustee initially named in this Indenture (or any successor thereto), is appointed with respect to one or more Series of Securities, the Corporation, the Trustee initially named in this Indenture (or any successor thereto) and such newly appointed trustee shall execute and deliver a supplement to this Indenture which shall contain such provisions as shall be necessary or desirable to confirm that all the rights, powers, trusts and duties of the Trustee initially named in this Indenture (or any successor thereto) with respect to the Securities of any Series as to which the Trustee is continuing as trustee hereunder shall continue to be vested in the Trustee initially named in this Indenture (or any successor thereto), and shall add to, supplement or change any of the provisions of this Indenture as shall be necessary or desirable to provide for or facilitate the administration of the trusts hereunder by more than one trustee, it being understood that nothing herein or in such

32

supplemental indenture shall constitute such trustees co-trustees of the same trust and that each such trustee shall be trustee of a trust or trusts relating to the separate Series of Securities as if it were acting under a separate indenture.

If a successor Trustee with respect to a Series of Securities does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Corporation or the Holders of a majority in aggregate principal amount of the then outstanding Securities of such Series issued pursuant to this Indenture (including any additional Securities issued pursuant to this Indenture after the Issue Date) may petition any court of competent jurisdiction for the appointment of a successor Trustee.

If the Trustee with respect to a Series of Securities fails to comply with Section 7.10, any Holder of Securities of that Series may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

If there are two or more Trustees at any time under this Indenture, each shall be the Trustee of a separate trust held under this Indenture for the benefit of the Series of Securities for which it is acting as Trustee and the rights and obligations of each Trustee will be determined as if it were acting under a separate indenture.

Section 7.9. Successor Trustee by Merger, etc. If the Trustee consolidates with, merges or converts into or transfers all or substantially all its corporate trust assets to another corporation, the resulting, surviving or transferee corporation without any further act shall be the successor Trustee.

Section 7.10. Eligibility; Disqualification . This Indenture shall always have a Trustee that satisfies the requirements of TIA § 310(a). The Trustee shall have a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of condition. The Trustee shall comply with TIA § 310(b), provided that the question whether the Trustee has a conflicting interest shall be determined as if each Series of Securities were a separate issue of securities issued under separate indentures.

Section 7.11. 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 therein.

Section 7.12. Trustee ’ s Application for Instructions from the Corporation . Any application by the Trustee for written instructions from the Corporation may, at the option of the Trustee, set forth in writing any action proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or after which such action shall be taken or such omission shall be effective. The Trustee shall not be liable for any action taken by, or omission of, the Trustee in accordance with a proposal included in such application on or after the date specified in such application (which date shall not be less than 20 Business Days after the date any officer of the Corporation actually receives such application, unless any such officer shall have consented in writing to any earlier date)

33

unless prior to taking any such action (or the effective date in the case of an omission), the Trustee shall have received written instructions in response to such application specifying the action to be taken or omitted.

Section 7.13. Calculations . The Corporation shall be responsible for making all calculations and determinations required under this Indenture, except in the case of the Calculation Agent’s determination of a floating rate of interest, as applicable. The Corporation shall make all calculations in good faith and, absent manifest error, the Corporation’s calculations shall be final and binding on all Holders of Securities. Upon written request, the Corporation shall provide a schedule of its calculations to the Trustee. The Trustee may rely conclusively upon the accuracy of the Corporation’s calculations without independent verification.

The Corporation’s exercise of its option under Section 8.2 or 8.3 shall not preclude the Corporation from subsequently exercising its option under Section 8.8 hereof and the Corporation may so exercise that option by providing the Trustee with written notice to such effect.

Section 8.2. Defeasance . Upon the Corporation’s exercise under Section 8.1 hereof of the option applicable to this Section 8.2, the Corporation shall, subject to the satisfaction of the conditions set forth in Section 8.4 hereof, be deemed to have been discharged from the obligations thereof with respect to all outstanding Securities of such Series on the date the conditions set forth below are satisfied (hereinafter, “defeasance”). For this purpose, defeasance means that the Corporation shall be deemed to have paid and discharged the entire Debt represented by the outstanding Securities of the applicable Series, which shall thereafter be deemed to be “outstanding” only for the purposes of Section 8.5 hereof and the other Sections of this Indenture referred to in (a) and (b) below, and to have satisfied all of its other obligations under such Securities and this Indenture (and the Trustee, on demand of and at the expense of the Corporation, shall execute proper instruments acknowledging the same), except for the following provisions which shall survive until otherwise terminated or discharged hereunder: (a) the rights of Holders of outstanding Securities of such Series to receive payments in respect of the principal of, premium, if any, and interest, if any, on such Securities when such payments are due from the trust referred to in Section 8.4(1); (b) the Corporation’s obligations with respect to such Securities under Sections 2.2, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9 and 2.11 hereof; (c) the rights, powers, trusts, benefits and immunities of the Trustee, including without limitation thereunder, under Section 7.7, 8.5 and 8.7 hereof and the Corporation’s obligations in connection therewith; (d) the Corporation’s rights pursuant to Article 3; and (e) the provisions of this Article 8.

For this purpose, covenant defeasance means that, with respect to the outstanding Securities of the applicable Series, the Corporation or any of its Subsidiaries 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 any 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 6.1 hereof with respect to such Series of Securities, but, except as specified above, the remainder of this Indenture and such Securities shall be unaffected thereby.

Section 8.4. Conditions to Defeasance or Covenant Defeasance . The following shall be the conditions to the application of Section 8.2 or 8.3 hereof to the outstanding Securities of any Series of Securities:

(2) the defeasance or covenant defeasance shall not result in a breach or violation of, or constitute a default under any material agreement or instrument (other than this Indenture or the applicable Series of Securities) to which the Corporation is a party or is bound;

35

(3) in the case of defeasance, the Corporation shall have delivered to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that:

(ii) the Corporation has received from, or there has been published by, the Internal Revenue Service a ruling; or

(iii) since the issue date of that particular Series of Securities under this Indenture, there has been a change in applicable U.S. federal income tax law,

in either case, to the effect that, and based on such ruling or change the Opinion of Counsel shall confirm that, the Holders of the Securities of the applicable Series will not recognize income, gain or loss for U.S. federal income tax purposes as a result of the 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 the defeasance had not occurred;

The Trustee shall hold in trust money and U.S. Government Obligations in respect of that Series deposited with it pursuant to Sections 8.4 or 8.8.

The Holder of any Security replaced pursuant to Section 2.7 shall not be entitled to any such payment and shall look only to the Corporation for any payment which such Holder may be entitled to collect. In connection with defeasance, covenant defeasance or the satisfaction and discharge of this Indenture with respect to Securities of a Series pursuant to Section 8.2, 8.3 or 8.8 hereof, respectively, the escrow trust agreement or other arrangement may, at the Corporation’s election, (1) enable the Corporation to direct the Trustee to invest any money received by the Trustee on the U.S. Government Obligations deposited in trust thereunder in additional U.S. Government Obligations and (2) enable the Corporation to withdraw moneys or U.S. Government Obligations from the trust from time to time; provided , however , that the condition specified in Section 8.4(1) or 8.8(1) is satisfied immediately following any investment of such money by the Trustee or the withdrawal of moneys or U. S. Government Obligations from the trust by the Corporation, as the case may be.

Section 8.6. Repayment to Corporation . The Trustee and the Paying Agent shall promptly pay to the Corporation upon request any excess money or securities held by them at any time.

Section 8.7. Reinstatement . If the Trustee or Paying Agent is unable to apply any United States dollars or U.S. Government Obligations in accordance with

37

Section 8.2, 8.3 or 8.8 hereof, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the obligations of the Corporation under this Indenture and the Securities of the applicable Series shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.2, 8.3 or 8.8 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.2, 8.3 or 8.8 hereof, as the case may be; provided , however , that, if the Corporation makes any payment of principal of, premium, if any, or interest on any Security following the reinstatement of its obligations, the Corporation shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money held by the Trustee or Paying Agent.

Section 8.8. Discharge . The Corporation may terminate all its obligations under this Indenture with respect to any or all Series of Securities, and, with respect to such Series of Securities, this Indenture shall cease to be of further effect, effective on the date the following conditions are satisfied:

(2) the Corporation has paid all other sums payable under this Indenture with respect to the Securities of such Series (including amounts payable to the Trustee); and

(3) the Trustee has received an Officers’ Certificate and an Opinion of Counsel to the effect that all conditions precedent to the satisfaction and discharge of this Indenture in respect of the Securities of such Series have been satisfied.

Notwithstanding the satisfaction and discharge of this Indenture with respect to any Series of Securities, the obligations of the Corporation to the Trustee under Section 7.7 and, if money shall have been deposited with the Trustee pursuant to subclause (B) of clause (1) of this Section 8.8, the obligations of the Corporation and the Trustee with respect to the Securities of such Series under Sections 8.5, 8.6 and 8.7, shall survive such satisfaction and discharge.

38

With the consent of the Holders of a majority in aggregate principal amount of the then outstanding Securities issued pursuant to this Indenture (including any additional Securities issued pursuant to this Indenture after the Issue Date), voting as a single class, the Corporation and the Trustee may amend this Indenture or enter into one or more supplemental indentures to this Indenture for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or the Securities or of modifying in any manner the rights of the Holders under this Indenture, including the definitions herein; provided that (i) if any such amendment or supplement would by its terms disproportionately and adversely affect any Series of Securities under this Indenture, such amendment or supplement shall also require the consent of the Holders of a majority in aggregate principal amount of the then outstanding Securities of such Series issued pursuant to this Indenture (including any additional Securities of such Series issued pursuant to this Indenture after the Issue Date) and (ii) if any such amendment or supplement would only affect the Securities of some but not all Series, then only the consent of the Holders of a majority in aggregate principal amount of the then outstanding Securities of all such affected Series issued pursuant to this Indenture (including any additional Securities of any such Series issued pursuant to this Indenture after the Issue Date) (and not the consent of a majority in aggregate principal amount of all the then outstanding Securities issued under this Indenture) shall be required; and provided , further , that the Corporation and the Trustee may not, without the consent of the Holder of each outstanding Security of a Series affected thereby:

(1) reduce the principal amount of Securities of such Series whose Holders must consent to an amendment, supplement or waiver;

40

The Holders of a majority in aggregate principal amount of the then outstanding Securities issued pursuant to this Indenture (including any additional Securities issued pursuant to this Indenture after the Issue Date), voting as a single class, may on behalf of the Holders of all the Securities issued pursuant to this Indenture waive any past Default under this Indenture and its consequences or compliance with any provisions of this Indenture or the Securities; provided that (i) if any such waiver would by its terms disproportionately and adversely affect any Series of Securities under this Indenture, such waiver shall also require the consent of the Holders of a majority in aggregate principal amount of the then outstanding Securities of such Series issued pursuant to this Indenture (including any additional Securities of such Series issued pursuant to this Indenture after the Issue Date) and (ii) if any such waiver would only affect the Securities of some but not all Series, then only the consent of the Holders of a majority in aggregate principal amount of the then outstanding Securities of all such affected Series issued pursuant to this Indenture (including any additional Securities of any such Series issued pursuant to this Indenture after the Issue Date) (and not the consent of a majority in aggregate principal amount of all the then outstanding Securities issued under this Indenture) shall be required; and provided , further , that no waiver shall be effective without the consent of the Holder of each outstanding Security affected thereby in the case of a Default (1) in any payment of principal, premium, if any, or interest due in respect of any Security or (2) in respect of other provisions which under this Indenture cannot be modified or amended without the consent of the Holder of each outstanding Security affected.

It shall not be necessary for the consent of the Holders under this Section 9.2 to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof.

Section 9.3. Compliance with Trust Indenture Act of 1939 . Every amendment or supplement to this Indenture or the Securities shall comply with the TIA as then in effect.

Section 9.4. Revocation and Effect of Consents . A consent to an amendment, supplement or waiver by a Holder of a Security shall bind the Holder and every subsequent Holder of that Security or portion of the Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent is not made on the Security. However, any such Holder or subsequent Holder may revoke the consent as to its Security or portion of the Security by delivery to the Trustee of written notice of revocation before the date the amendment, supplement or waiver becomes effective.

After an amendment, supplement or waiver becomes effective, it shall bind every Holder unless it makes a change described in the second proviso in the first or second paragraphs of Section 9.2. In that case, the amendment, supplement or waiver shall bind each Holder of a Security who has consented to it and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security.

41

Section 9.5. Notation on or Exchange of Securities . If an amendment, supplement or waiver changes the terms of a Security, the Trustee may require the Holder of the Security to deliver it to the Trustee. The Trustee may place an appropriate notation on the Security about the changed terms and return it to the Holder. Alternatively, if the Corporation or the Trustee so determine, the Corporation in exchange for the Security shall issue and the Trustee shall authenticate a new Security of the same Series that reflects the changed terms.

Failure to make the appropriate notation or issue a new Security shall not affect the validity and effect of such amendment, supplement or waiver

Section 9.6. Trustee to Sign Amendments, etc . The Trustee shall sign any amendment, supplement or waiver authorized pursuant to this Article 9 if the amendment, supplement or waiver does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If such amendment, supplement or waiver does so adversely affect the Trustee, the Trustee may but need not sign it. In signing such amendment, supplement or waiver the Trustee shall be entitled to receive, and (subject to Section 7.1) shall be fully protected in relying upon (in addition to the documents provided for under Section 10.4), an Officers’ Certificate and Opinion of Counsel stating that such amendment, supplement or waiver is authorized or permitted by this Indenture.

Section 10.11. Securities in a Foreign Currency . Unless otherwise specified in an Officers’ Certificate delivered pursuant to Section 2.1 of this Indenture with respect to a particular Series of Securities, whenever for purposes of this Indenture any action may be taken by the holders of a specified percentage in aggregate principal amount of Securities of all Series at the time outstanding and, at such time, there are outstanding Securities of any Series which are denominated in a Foreign Currency, then the principal amount of Securities of such Series which shall be deemed to be outstanding for the purpose of taking such action shall be that amount of U.S. dollars that could be obtained for such amount at the Market Exchange Rate on the record date fixed for such action or, if no record date is fixed, on the Business Day immediately preceding the date of such action.

Section 10.12. Judgment Currency . If, for the purpose of obtaining a judgment in any court with respect to any obligation of the Corporation hereunder or under any Security, it shall become necessary to convert into any other currency any amount in the currency due hereunder or under such Security, then such conversion shall be made by the Trustee (a) with respect to conversions between any Foreign Currency and U.S. dollars at the Market Exchange Rate as in effect on the date of entry of the judgment (the “Judgment Date”) and (b) with respect to conversions of any Foreign Currency into any other Foreign Currency by (i) converting such Foreign Currency into U.S. dollars at the Market Exchange Rate as in effect on the Judgment Date and (ii) converting the sum of U.S. dollars so obtained into such other Foreign Currency at the Market Exchange Rate as in effect on the Judgment Date.

45

any, as may be necessary to ensure that the amount paid is equal to the amount in such other currency which, when converted at such Market Exchange Rate as in effect on the Judgment Date, is the amount due hereunder or under such Security. Any amount due from the Corporation under this Section 10.12 shall be due as a separate debt and is not to be affected by or merged into any judgment being obtained for any other sums due hereunder or in respect of any Security. In no event, however, shall the Corporation be required to pay more in the currency due hereunder or under such Security at the Market Exchange Rate as in effect on the Judgment Date than the amount of currency stated to be due hereunder or under such Security so that in any event the Corporation’s obligations hereunder or under such Security will be effectively maintained as obligations in such currency, and the Corporation shall be entitled to withhold (or be reimbursed for, as the case may be) any excess of the amount actually realized upon any such conversion on the Substitute Date over the amount due and payable on the Judgment Date.

Section 10.13. Successors . All agreements of the Corporation in this Indenture and the Securities shall bind its successor. All agreements of the Trustee in this Indenture shall bind its successor.

Section 10.14. Duplicate Originals . The parties may sign any number of copies of this Indenture. Each signed copy (including via PDF) shall be an original, but all of them together represent the same agreement.

(a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by agent duly appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Corporation. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and conclusive in favor of the Trustee and the Corporation, if made in the manner provided in this Section 10.15. Notwithstanding the foregoing, 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 the Depositary or impairing, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a Holder of any Security.

(b) The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgements of deeds, certifying that the individual signing such instrument or writing acknowledged to such officer the execution thereof. Where such execution is by a signer acting in a capacity other than such signer’s individual capacity, such certificate or affidavit shall also constitute sufficient proof of such signer’s authority. The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner which the Trustee deems sufficient.

46

(c) The Corporation may, in the circumstances permitted by the TIA, fix any day as the record date for the purpose of determining the Holders of Securities of any Series entitled to give or take any request, demand, authorization, direction, notice, consent, wavier or other action, or to vote on any action, authorized or permitted to be given or taken by Holders of Securities of such Series. If not set by the Corporation prior to the first solicitation of a Holder of Securities of such Series made by any person in respect of any such action, or, in the case of any such vote, prior to such vote, the record date for any such action or vote shall be the 30th day (or, if later, the date of the most recent list of Holders required to be provided pursuant to Section 2.6) prior to such first solicitation or vote, as the case may be. With regard to any record date for action to be taken by the Holders of one or more Series of Securities, only the Holders of Securities of such Series on such date (or their duly designated proxies) shall be entitled to give or take, or vote on, the relevant action.

Section 10.16. Force Majeure . In no event shall the Trustee be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software or hardware) services; it being understood that the Trustee shall use reasonable efforts which are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances.

Section 10.18. U.S.A. PATRIOT Act . The parties hereto acknowledge that in accordance with Section 326 of the U.S.A. PATRIOT Act, the Trustee is required to obtain, verify, and record information that identifies each person or legal entity that establishes a relationship or opens an account with the Trustee.

Section 10.19. Severability . In case any provision in this Indenture or in the Securities 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 10.20. Waiver of Jury Trial . EACH OF THE CORPORATION, THE HOLDERS AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT

47

TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE SECURITIES, OR THE TRANSACTION CONTEMPLATED THEREBY.

Section 10.21. Venue . The Corporation hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Indenture or the Securities in any New York State or federal court. Each of the parties hereto irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

If the notice is sent prior to the date of consummation of the Change of Control, the notice shall state that the Change of Control Offer is conditioned on the Change of Control Repurchase Event occurring on or prior to the repurchase date specified in the notice.

(e) The Corporation shall not be required to make an offer to repurchase the Notes upon a Change of Control Repurchase Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements of this Section 4.3 and such third party purchases all Notes properly tendered and not withdrawn by the Holders thereof under its offer.

(f) If Notes tendered in a Change of Control Offer are paid or if the Corporation has deposited with the Trustee or the Paying Agent money sufficient to pay the repurchase price of all Notes to be repurchased, on and after the repurchase date, interest shall cease to accrue on the Notes or the portions of Notes tendered and not withdrawn in a Change of Control Offer (regardless of whether certificates for such Notes are actually surrendered). If any Security tendered in a Change of Control Offer shall not be so paid upon surrender for repurchase because of the failure of the Corporation to comply with paragraph (c) of this Section 4.3, interest shall be paid on the unpaid principal from the repurchase date until such principal is paid, and, to the extent lawful, on any interest not paid on such unpaid principal, in each case, at the rate provided in such Security.

This Section 4.3 is one of the covenants eligible for the provisions of Section 8.3 of the Indenture.

Martin Marietta Materials, Inc., a North Carolina corporation, or its successor (the “Corporation”), promises to pay interest on the outstanding principal amount of this Floating Rate Note at the rate determined below, and at the same rate on any overdue principal or overdue installment of interest to the extent lawful. This Floating Rate Note shall bear interest in United States dollars at a per annum floating rate, reset quarterly for each Interest Period, equal to three-month LIBOR for U.S. dollars, determined on the Interest Determination Date for such Interest Period, plus 0.650% (or 65 basis points). Interest on this Floating Rate Note shall be payable quarterly in arrears on February 22, May 22, August 22 and November 22, commencing August 22, 2017 (each, an “Interest Payment Date”), except as provided in Section 10.7 of the Indenture with respect to an Interest Payment Date that is not a Business Day. Interest on this Floating Rate Note shall accrue from, and including, the most recent date to which interest has been paid or, if no interest has been paid, from and including May 22, 2017. The interest rate on this Floating Rate Note shall in no event be higher than the maximum rate permitted by New York law or other applicable state law, as the same may be modified by United States law of general application.

The amount of interest for each day that this Floating Rate Note is outstanding (the “daily interest amount”) shall be calculated by dividing the interest rate in effect for such day by 360 and multiplying the result by the outstanding principal amount of this Floating Rate Note on such day. The amount of interest to be paid on this Floating Rate Note for any Interest Period shall be calculated by adding the daily interest amounts for each day in such Interest Period.

The interest rate and amount of interest to be paid on this Floating Rate Note for each Interest Period shall be calculated by the Calculation Agent. All calculations made by the Calculation Agent shall, in the absence of manifest error, be conclusive for all purposes and binding on the Corporation and the Holders of this Floating Rate Note.

All percentages resulting from any calculation of the interest rate on this Floating Rate Note shall be rounded to the nearest one hundred-thousandth of a percentage point with five one millionths of a percentage point rounded upwards ( e.g. , 9.876545% (or .09876545) would be rounded to 9.87655% (or .0987655)), and all dollar amounts used in or resulting from such calculation on this Floating Rate Note shall be rounded to the nearest cent (with one-half cent being rounded upward).

Upon request from any Holder of this Floating Rate Note, the Calculation Agent shall provide the interest rate in effect for this Floating Rate Note for the current Interest Period and, if it has been determined, the interest rate to be in effect for the next Interest Period.

This Floating Rate Note shall be payable as to principal, premium and interest at the office or agency of the Corporation maintained for such purpose within the Borough of Manhattan, The City and State of New York; provided that (a) payment by wire transfer of immediately available funds shall be required with respect to principal of, premium, if any, and interest on, all Global Securities and (b) at the option of the Corporation, payment of interest on an Interest Payment Date may be made by check mailed to a Holder’s address. Such payment shall be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts.

Any payments of principal of, premium, if any, and interest on this Floating Rate Note prior to the Stated Maturity Date shall be binding upon all future Holders of this Floating Rate Note, whether or not noted hereon. The amount due and payable at the maturity or earlier redemption or repurchase of this Floating Rate Note shall be payable only upon presentation and surrender of this Floating Rate Note at an office of the Trustee or the Trustee’s agent appointed for such purposes.

(3) Paying Agent, Registrar and Calculation Agent. Initially the Trustee under the Indenture, shall act as Paying Agent, Registrar and Calculation Agent. The Corporation may change any Paying Agent, Registrar or Calculation Agent for any reason (and shall change the Calculation Agent if it shall be unable or unwilling to act or if it shall fail duly to establish three-month LIBOR for any Interest Period), without notice to any Holder. The Corporation or any of its Subsidiaries may act in any such capacity, except in the case of the Calculation Agent, where the Corporation may appoint another Person which is a bank, trust company, investment banking firm or other financial institution to act as such.
