In lieu of delivery of a new Unit Certificate, upon satisfaction of the applicable conditions specified in clauses (i) and (ii) of the preceding paragraph, the Agent shall deliver or cause to be delivered on the applicable Settlement Date or redemption date (i) in respect of Purchase Contracts or Debt Securities constituting a part of the Units evidenced by such Unit Certificate that are selected or called for redemption, the redemption price of such Purchase Contracts or Debt Securities or (ii) in respect of Purchase Contracts constituting a part of the Units evidenced by such Unit Certificate with respect to which a Cash Settlement or Debt Security Settlement (or any equivalent manner of settlement) has taken place, (x) the Purchase Contract Property (or cash value thereof), purchase price, cash settlement value, Settlement Amount or other amount, as the case may be, deliverable with respect to such Purchase Contracts (and, in the case of an effective Cash Settlement (or any equivalent manner of settlement), the related Debt Securities) or (y) if a Purchase Contract Default has occurred by virtue of the Corporation’s having failed to deliver the Purchase Contract Property (or cash value thereof), purchase price, cash settlement value, Settlement Amount or other amount, as the case may be, deliverable against tender by the Agent of the purchase price, Purchase Contract Property (or the cash value thereof) or other Settlement Amount or other amount, as the case may be, such purchase price, Purchase Contract Property (or cash value thereof) or Settlement Amount or other amount, if any, received by the Agent from the Holder in respect of the Settlement of such Purchase Contracts or in respect of principal with respect to the related Debt Securities received by the Agent.

Upon the issuance of any new Unit Certificate under this Section, the Corporation and the Agent may require the payment of a sum sufficient to cover any tax or

other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Agent) connected therewith.

Every new Unit Certificate executed pursuant to this Section in lieu of any destroyed, lost or stolen Unit Certificate shall constitute an original additional contractual obligation of the Corporation and of the Holder (with respect to any Purchase Contracts constituting a part of the Units evidenced thereby), whether or not the destroyed, lost or stolen Unit Certificate (and the Securities evidenced thereby) shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Agreement equally and proportionately with any and all other Unit Certificates delivered hereunder.

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

SECTION 2.10. Persons Deemed Owners. Prior to due presentment of a Unit Certificate of any series for registration of transfer, the Corporation, the Trustee, the Collateral Agent and the Agent, as appropriate, and any agent of the Corporation, the Trustee, the Collateral Agent or the Agent, as appropriate, may treat the Person in whose name any Registered Security evidenced by such Unit Certificate is registered and, with respect to any Unregistered Security constituting a part of the Units evidenced by such Unit Certificate, the bearer thereof, as the owner of the Units evidenced thereby for all purposes whatsoever, whether or not payment with respect to any Security constituting a part of the Units evidenced thereby shall be overdue and notwithstanding any notice to the contrary. None of the Corporation, the Trustee, the Agent, the Collateral Agent or any agent of the Corporation, the Trustee, the Collateral Agent or the Agent shall be affected by notice to the contrary.

SECTION 2.11. Cancellation. Subject to Section 3.07, all Unit Certificates surrendered for payment, and all Unit Certificates surrendered for redemption of any Debt Securities or Purchase Contracts evidenced thereby, termination or settlement of any Purchase Contracts evidenced thereby, delivery of Purchase Contract Property or registration of transfer or exchange shall, if surrendered to any Person other than the Trustee or the Agent, as appropriate, be delivered to the Trustee and/or the Agent, as appropriate, and, if not already cancelled, any Debt Securities or Purchase Contracts evidenced by such Units shall be promptly cancelled by the Trustee and/or the Agent, as appropriate. The Corporation may at any time deliver to the Trustee and/or the Agent, as appropriate, for cancellation any Unit Certificates previously authenticated, countersigned, executed and delivered hereunder under the Indenture, which the Corporation may have acquired in any manner whatsoever, and all Unit Certificates so delivered shall, upon Issuer Order of the Corporation, be promptly cancelled by the Trustee and/or the Agent, as appropriate. No Unit Certificates shall be authenticated, countersigned and executed in lieu of or in exchange for any Unit Certificates cancelled as provided in this Section, except as permitted by this Agreement. All cancelled Unit Certificates held by the Agent shall be disposed of in accordance with its customary procedures and a certificate of their disposition shall be delivered by the Agent to the

Corporation, unless by Issuer Order the Corporation shall direct that cancelled Unit Certificates be returned to it.

If the Corporation or any Affiliate of the Corporation shall acquire any Unit Certificate, such acquisition shall not operate as a cancellation of such Unit Certificate unless and until such Unit Certificate is delivered to the Trustee and/or the Agent, as appropriate, for the purpose of cancellation.

SECTION 2.12. Exchange of Global Units and Definitive Units. In the case of Registered Units, Holders of Global Units of any series shall receive Definitive Units of such series in exchange for interests in such Global Units if DTC notifies the Corporation that it is unwilling or unable to continue as Depositary with respect to the Global Units of such series or if at any time it ceases to be a clearing agency under the Exchange Act, and a successor Depositary registered as a clearing agency under the Exchange Act is not appointed by the Corporation within 90 days after receipt of such notice or after it becomes aware that DTC has ceased to be such a clearing agency.

If so provided pursuant to Section 2.03, interests in such Global Units may also be transferred or exchanged for Definitive Units upon the request of the Depositary to the Trustee and/or the Agent, as appropriate, to authenticate, countersign and execute, as the case may be, Unit Certificates representing Definitive Units (such request being referred to herein as an “Optional Definitive Unit Request”).

Definitive Units exchanged for interests in Global Units pursuant to this Section 2.12 shall be denominated in the amounts and registered in the name of such Person or Persons as the Depositary shall instruct the Agent and the Trustee, as appropriate.

Whenever Global Units are exchanged for Definitive Units, the Agent shall cause Schedule A of the Global Unit to be endorsed to reflect any decrease in the Global Units as a result of such exchange, whereupon the Global Unit Certificate or Certificates shall be canceled and disposed of in accordance with Section 2.11.

If so specified pursuant to Section 2.03, Holders of Definitive Units may transfer or exchange such Definitive Units for interests in Global Units by depositing the Unit Certificates evidencing such Definitive Units with the Agent and requesting the Agent, and the Trustee, as appropriate, to effect such exchange. The Agent shall notify the Depositary of any such exchange and, upon delivery to the Agent and the Trustee, as appropriate, of the Unit Certificates evidencing the Definitive Units to be so transferred or exchanged, the Agent shall take all actions required with respect to any Global Securities evidenced by such Global Units and Unit Certificates evidencing the remaining Definitive Units, if any, will be issued in accordance with Section 2.08.

SECTION 3.01. Form and Execution of Purchase Contracts; Temporary Purchase Contracts. (a) Purchase Contracts of each series shall be substantially in the forms attached as Exhibit A, as appropriate, or in such form (not inconsistent with this Agreement) as shall be established by or pursuant to one or more Board Resolutions (as set forth in a Board Resolution or, to the extent established pursuant to rather than set forth in a Board Resolution, an Officers’ Certificate detailing such establishment, in each case, which may be included in any Board Resolution or Officers’ Certificate made pursuant to this Agreement) or in one or more agreements supplemental hereto, in each case with such appropriate insertions, omissions, substitutions and other variations as are required or permitted by this Agreement. The Purchase Contracts may have imprinted or otherwise reproduced thereon such letters, numbers or other marks of identification or designation and such legends or endorsements as the officers of the Corporation executing the same may approve (execution thereof to be conclusive evidence of such approval) and that are not inconsistent with the provisions of this Agreement, or as may be required to comply with any law or with any rule or regulation made pursuant thereto, or with any rule or regulation of any SRO on which the Purchase Contracts of such series may be listed or quoted, or of any securities depository, or to conform to general usage. Purchase Contracts shall be signed on behalf of the Corporation by the chairman or vice chairman of the Board of Directors, the president, a vice president, the treasurer or an assistant treasurer the Corporation or such other person specifically designated by the Board of Directors or the Executive Committee thereof to execute Purchase Contracts, which signature may or may not be attested by the secretary or an assistant secretary of the Corporation. The signature of any of such officers may be either manual or facsimile. Typographical and other minor errors or defects in any such signature shall not affect the validity or enforceability of any Purchase Contract that has been duly countersigned and delivered by the Agent.

(b) In case any officer of the Corporation who shall have signed a Purchase Contract, either manually or by facsimile signature, shall cease to be such officer before such Purchase Contract shall have been countersigned and delivered by the Agent to the Corporation or delivered by the Corporation, such Purchase Contract nevertheless may be countersigned and delivered as though the person who signed such Purchase Contract had not ceased to be such officer of the Corporation; and a Purchase Contract may be signed on behalf of the Corporation by any person who, at the actual date of the execution of such Purchase Contract, shall be a proper officer of the Corporation to sign such Purchase Contract, although at the date of the execution of this Agreement any such person was not such officer.

(c) Pending the preparation of final Purchase Contracts of any series, the Corporation may execute and the Agent shall countersign and deliver temporary Purchase Contracts (printed, lithographed, typewritten or otherwise produced, in each case in form satisfactory to the Agent). Such temporary Purchase Contracts shall be issuable substantially in the form of the final Purchase Contracts but with such omissions, insertions and variations

as may be appropriate for temporary Purchase Contracts, all as may be determined by the Corporation with the concurrence of the Agent. Such temporary Purchase Contracts may contain such reference to any provisions of this Agreement as may be appropriate. Every such temporary Purchase Contract shall be executed by the Corporation and shall be countersigned by the Agent upon the same conditions and in substantially the same manner, and with like effect, as the final Purchase Contracts. Without unreasonable delay, the Corporation shall execute and shall furnish final Purchase Contracts and thereupon such temporary Purchase Contracts may be surrendered in exchange therefor without charge, and the Agent shall countersign and deliver in exchange for such temporary Purchase Contracts final Purchase Contracts evidencing a like aggregate number of Purchase Contracts of the same series and of like tenor as those evidenced by such temporary Purchase Contracts. Until so exchanged, such temporary Purchase Contracts shall be entitled to the same benefits under this Agreement as final Purchase Contracts.

SECTION 3.02. Number Unlimited Issuable in Series. (a) The aggregate number of Purchase Contracts that may be delivered under this Agreement is unlimited.

(b) The Purchase Contracts may be issued in one or more series. There shall be established in or pursuant to one or more Board Resolutions (and to the extent established pursuant to rather than set forth in a Board Resolution, in an Officers’ Certificate detailing such establishment) or established in one or more agreements supplemental hereto, prior to the initial issuance of Purchase Contracts of any series:

(i) the designation of the Purchase Contracts of the series, which shall distinguish the Purchase Contracts of the series from the Purchase Contracts of all other series;

(ii) any limit upon the aggregate number of the Purchase Contracts of the series that may be countersigned and delivered under this Agreement (except for Purchase Contracts countersigned and delivered upon registration of transfer of, or in exchange for, or in lieu of, other Purchase Contracts of the series);

(iii) the specific property (the “Purchase Contract Property”) used to determine the amount payable upon settlement of the Purchase Contracts of the series, and the amount of such property (or the method for determining the same);

(iv) whether the Purchase Contracts of the series provide for the purchase by the Corporation and the sale by the Holder or the sale by the Corporation and the purchase by the Holder of the Purchase Contract Property;

(v) in the case of Purchase Contracts that obligate the Corporation to sell, and the Holder to purchase, Purchase Contract Property, the Purchase Price at which and, if other than U.S. Dollars, the coin or currency with which the Purchase Contract Property is to be purchased by the Holder upon

settlement of the Purchase Contracts of the series (or the method for determining the same) and whether the Purchase Price for such Purchase Contracts may be paid in cash or by the exchange of any other security of the Corporation, or both, or otherwise;

(vi) in the case of Purchase Contracts that obligate the Corporation to purchase, and the Holders to sell, Purchase Contract Property, the Settlement Amount for the Purchase Contracts of the series (or the method for determining the same) and, if other than U.S. Dollars, the coin or currency in which such Settlement Amount is to be paid;

(vii) whether the settlement of the Purchase Contracts of the series is to be in cash or by delivery of the Purchase Contract Property, or otherwise, and the method of settlement of the Purchase Contracts of the series;

(viii) the specific date or dates on which the Purchase Contracts will be settled, whether the settlement may be accelerated by the Corporation or the Holders thereof and, if so, the initial accelerated settlement date, the minimum number of Purchase Contracts that may be accelerated and the minimum number of Purchase Contracts greater than zero that must remain Outstanding immediately following such acceleration;

(ix) whether the Purchase Contracts of the series will be in registered form (“Registered Purchase Contracts”) or bearer form (“Bearer Purchase Contracts”) or both;

(x) whether any Purchase Contracts of the series will be issued in global form or definitive form or both, and whether and on what terms (if different from those set forth herein) Purchase Contracts in one form may be converted into or exchanged for Purchase Contracts in the other form;

(xi) any agents, depositaries, authenticating or paying agents, transfer agents or registrars or any determination or calculation agents or other agents with respect to Purchase Contracts of the series;

(xii) whether and on what terms the Purchase Contracts of the series may be separated from the other components of the Units of which the Purchase Contracts are a component;

(xiii) whether the Purchase Contracts of such series will be subject to redemption by the Corporation and, if so, the initial redemption date, the minimum number of Purchase Contracts that may be redeemed and the minimum number of Purchase Contracts greater than zero that must remain Outstanding immediately following such redemption; and

(xiv) any other terms of the Purchase Contracts of the series (which terms shall not be inconsistent with the provisions of this Agreement).

(c) All Purchase Contracts of any one series shall be substantially identical, except as may otherwise be provided by or pursuant to the Board Resolution or Officers’ Certificate referred to above or as set forth in any such agreement supplemental hereto. All Purchase Contracts of any one series need not be issued at the same time and may be issued from time to time, consistent with the terms of this Agreement, if so provided by or pursuant to such Board Resolution, such Officers’ Certificate or in any such agreement supplemental hereto.

SECTION 3.03. Countersignature, Execution on Behalf of Holder and Delivery of Purchase Contracts. (a) The Corporation may deliver Purchase Contracts of any series executed by the Corporation to the Agent for countersignature and execution on behalf of the Holders, together with the applicable documents referred to below in this Section, and the Agent shall thereupon countersign, execute on behalf of the Holders and deliver such Purchase Contracts to or upon the order of the Corporation (contained in the Issuer Order referred to below in this Section) or pursuant to such procedures acceptable to the Agent as may be specified from time to time by an Issuer Order. If provided for in such procedures, such Issuer order may authorize countersignature, execution on behalf of the Holders and delivery pursuant to oral instructions from the Corporation or its duly authorized agent, which instructions shall be promptly confirmed in writing. In countersigning such Purchase Contracts, executing such Purchase Contracts on behalf of the Holders and accepting the responsibilities under this Agreement in relation to the Purchase Contracts, the Agent shall be entitled to receive (in the case of subparagraphs (ii), (iii) and (iv) below only at or before the time of the first request of the Corporation to the Agent to countersign and execute on behalf of the Holders Purchase Contracts in a particular form) and shall be fully protected in relying upon, unless and until such documents have been superseded or revoked:

(i) an Issuer Order requesting such countersignature and execution and setting forth delivery instructions if the Purchase Contracts are not to be delivered to the Corporation;

(ii) any Board Resolution, Officers’ Certificate and/or executed supplemental agreement pursuant to which the forms and terms of the Purchase Contracts were established;

(iii) an Officers’ Certificate setting forth the forms and terms of the Purchase Contracts, stating that the form or forms and terms of such Purchase Contracts have been established pursuant to Sections 3.01 and 3.02 and comply with this Agreement, and covering such other matters as the Agent may reasonably request; and

(iv) at the option of the Corporation, either an Opinion of Counsel or a letter addressed to the Agent permitting it to rely on an Opinion of Counsel, substantially to the effect that:

(A) the forms of the Purchase Contracts have been duly authorized and established in conformity with the provisions of this Agreement;

(B) the terms of the Purchase Contracts have been duly authorized and established in conformity with the provisions of this Agreement and certain terms of the Purchase Contracts have been established pursuant to a Board Resolution, an Officers’ Certificate or a supplemental agreement in accordance with this Agreement, and when such other terms as are to be established pursuant to procedures set forth in an Issuer Order shall have been established, all terms will have been duly authorized by the Corporation and will have been established in conformity with the provisions of this Agreement; and

(C) when the Purchase Contracts have been executed by the Corporation and by the Agent on behalf of the Holders and countersigned by the Agent in accordance with the provisions of this Agreement and delivered to and duly paid for by the purchasers thereof, subject to such other conditions as may be set forth in such Opinion of Counsel, they will have been duly issued under this Agreement and will be valid and legally binding obligations of the Corporation, enforceable in accordance with their respective terms, and will be entitled to the benefits of this Agreement.

In rendering such opinions, such counsel may qualify any opinions as to enforceability by stating that such enforceability may be limited by bankruptcy, insolvency, reorganization, liquidation, moratorium and other similar laws affecting the rights and remedies of creditors and is subject to general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law). Such counsel may rely upon opinions of other counsel (copies of which shall be delivered to the Agent), who shall be counsel reasonably satisfactory to the Agent, in which case the opinion shall state that such counsel believes he and the Agent are entitled so to rely. Such counsel may also state that, insofar as such opinion involves factual matters, he has relied, to the extent he deems proper, upon certificates of officers of the Corporation and its subsidiaries and certificates of public officials.

(b) The Agent shall have the right to decline to countersign, execute on behalf of the Holders and deliver any Purchase Contract under this Section if the Agent, being advised by counsel, determines that such action may not lawfully be taken by the Corporation or if the Agent in good faith by its board of directors or board of trustees determines that such action would expose the Agent to personal liability to existing registered or beneficial holders of Purchase Contracts or would affect the Agent’s own rights, duties or immunities under the Purchase Contracts, this Agreement or otherwise.

(c) If the Corporation shall establish pursuant to Section 3.02 that the Purchase Contracts of a series are to be evidenced by one or more Global Purchase Contracts, then unless otherwise agreed between the Corporation and the Agent the Corporation shall execute and the Agent shall, in accordance with this Section and the Issuer Order with respect to such series, countersign, execute on behalf of the Holders and deliver one or more Global Purchase Contracts that (i) shall evidence all or a portion of the Purchase Contracts of such series issued in such form and not yet cancelled, (ii) in the case of Registered Purchase Contracts, shall be registered in the name of the Depositary for such Purchase Contracts or the nominee of such Depositary, (iii) shall be delivered by the Agent to such Depositary or pursuant to such Depositary’s instructions and (iv) in the case of Registered Purchase Contracts, shall bear a legend substantially to the following effect: “Unless and until it is exchanged in whole or in part for Purchase Contracts in definitive registered form, this Purchase Contract may not be transferred except as a whole by the Depositary to the 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 such nominee to a successor Depositary or a nominee of such successor Depositary.”

(d) If so required by applicable law, each Depositary for a series of Registered Purchase Contracts must, at the time of its designation and at all times while it serves as Depositary, be a clearing agency registered under the Securities Exchange Act of 1934, as amended, and any other applicable statute or regulation.

(e) Each Purchase Contract shall be dated the date of its countersignature. A Purchase Contract shall not be valid for any purpose, unless and until such Purchase Contract has been executed by the Agent on behalf of the Holder and countersigned by the manual signature of an authorized officer of the Agent. Such countersignature by an authorized officer of the Agent upon any Purchase Contract executed by the Corporation in accordance with this Agreement shall be conclusive evidence that the Purchase Contract so countersigned has been duly delivered and issued hereunder.

SECTION 3.04. Further Provisions Relating to Issuance of Purchase Contracts. Purchase Contracts may be executed by the Corporation and delivered to the Agent upon the execution of this Agreement or from time to time thereafter and in connection with exchanges, substitutions and transfers of Units of any series. Subsequent to the original issuance of the Purchase Contracts, the Agent shall, subject to the conditions set forth in this Article and Article Two, countersign and execute on behalf of the Holder Purchase Contracts issued in exchange or substitution for or upon transfer of Unit Certificates evidencing one or more previously countersigned and executed Unsettled Purchase Contracts evidenced by the Unit Certificates to be exchanged, substituted for or transferred.

SECTION 3.05. Purchase of Purchase Contract Property; Optional Acceleration of Purchase Obligations; Authorization of Agent by Holder; Transferees Bound. (a) Unless otherwise specified pursuant to Section 3.02, the Unsettled Purchase Contracts of any series will either (i) obligate the Holders thereof to purchase, and the

Corporation to sell or deliver the cash value of, Purchase Contract Property or (ii) obligate the Corporation to purchase, and the Holders thereof to sell or deliver the cash value of, Purchase Contract Property, in each case specified pursuant to Section 3.02 (or a quantity calculated by a method specified pursuant to Section 3.02) on the Stated Settlement Date at the Purchase Price specified pursuant to Section 3.02.

(b) If this Section is specified as applicable pursuant to Section 3.02, the Corporation may, subject to paragraph (c) of this Section, at its sole option and in its sole discretion at any time or from time to time (unless otherwise specified pursuant to Section 3.02) on not less than 30 nor more than 60 days’ written notice (an “Acceleration Notice”) to the Agent and the Holders, in the manner provided in Section 11.05 and Section 11.06, respectively, accelerate the obligations of the Holders of at least the Minimum Acceleration Amount of Unsettled Purchase Contracts to purchase or sell, as the case may be, and of the Corporation to sell or purchase, as the case may be, on any Accelerated Settlement Date (provided that such Accelerated Settlement Date may not be prior to the Initial Acceleration Date), the quantity of Purchase Contract Property specified pursuant to Section 3.02 for each Unsettled Purchase Contract subject to such acceleration; provided that no such acceleration with respect to fewer than all Unsettled Purchase Contracts shall (unless otherwise specified pursuant to Section 3.02) result in fewer than the Minimum Remaining Amount of Unsettled Purchase Contracts remaining Outstanding after such Accelerated Settlement Date; and provided further that the Corporation shall have the right, in its sole discretion, on or before the 10th day prior to such Accelerated Settlement Date, to rescind any Acceleration Notice by written notice to the Agent and written notice to the Holders pursuant to Sections 11.05 and 11.06 (whereupon all rights and obligations of the Corporation and the Holders that would have arisen as a result of such Acceleration Notice shall be of no force and effect), without prejudice to the rights of the Corporation, including without limitation its rights to deliver an Acceleration Notice in the future. If fewer than all Unsettled Purchase Contracts of such series are to be accelerated to a particular Accelerated Settlement Date, the Agent shall select from among the Unsettled Purchase Contracts such number thereof as are being accelerated on a pro rata basis, by lot or by such other means reasonably acceptable to the Agent, with appropriate adjustment being made to prevent the fractional acceleration of the settlement of Purchase Contracts, such that the settlement of Purchase Contracts are accelerated only in whole and not in part.

(c) Each Holder of a Unit, by his acceptance thereof, authorizes and directs the Agent to enter into, deliver and perform any Purchase Contracts that are part of such Unit on his behalf, agrees to be bound by the terms and provisions thereof, covenants and agrees to perform its obligations under the Purchase Contracts evidenced by such Unit, and consents and agrees to the provisions hereof. If the provisions of Section 3.06 are applicable to the Units of any series, each Holder of a Unit of such series, by his acceptance thereof, further covenants and agrees that, to the extent such Holder is deemed to have elected to satisfy its obligations under any Purchase Contracts that are part of such Unit by effecting a Debt Security Settlement as provided in Section 3.06, and subject to the terms thereof, redemption payments with respect to principal of any Debt Securities that are part of such Unit shall be

applied by the Agent in satisfaction of such Holder’s obligations under such Purchase Contract on the applicable Settlement Date.

(d) Upon registration of transfer of a Purchase Contract of any series, the transferee shall be bound (without the necessity of any other action on the part of such transferee, except as may be required by the Agent pursuant to this Article Three) under the terms of this Agreement and such Purchase Contract, and the transferor shall be released from the obligations under the Purchase Contract so transferred.

(e) Each Holder of a Unit of any series, by his acceptance thereof, authorizes the Agent to execute on his behalf any Purchase Contracts that are part of such Unit, authorizes and directs the Agent on his behalf to take such other action (including without limitation any actions required under Article Five), and covenants and agrees to take such other action as may be necessary or appropriate, or as may be required by the Agent, to effect the provisions of this Agreement, the Units and the Purchase Contracts and appoints the Agent as his attorney-in-fact for any and all such purposes.

SECTION 3.06. Payment of Purchase Price. (a) Unless otherwise specified pursuant to Section 3.02 (in the case of a Unit of any series consisting of a Debt Security and a Purchase Contract that obligates the Corporation to sell, and the Holder to purchase, Purchase Contract Property), the Purchase Price for any Purchase Contract Property purchased by a Holder pursuant to such Purchase Contract shall be payable at the Corporate Trust Office of the Agent:

(i) at the option of the Holder of the Unit of which such Purchase Contract is part, after receipt by the Agent of written notice from the Holder not less than 10 days nor more than 20 days prior to the applicable Settlement Date indicating the Holder’s choice of cash settlement, by delivery by such Holder not later than 11:00 a.m., New York City time, on the Business Day immediately preceding the Settlement Date of the Purchase Price (a “Cash Settlement”), to the Agent in immediately available funds payable to or upon the order of the Corporation; or

(ii) by application of any payment received by the Agent, Collateral Agent, Trustee or Paying Agent with respect to the principal of any Debt Security included in the Unit of which such Purchase Contract constitutes a part, as provided in paragraph (f) of this Section (a “Debt Security Settlement”).

A Holder of such Units who fails to provide notice to the Agent as provided above that it will make a Cash Settlement with respect to the settlement of a Purchase Contract, or a Holder of such Units who provides such notice but does not effect a Cash Settlement in accordance with the terms of this Section 3.06, will be deemed to have elected to have the Purchase Price for the Purchase Contract Property paid pursuant to a Debt Security Settlement.

(b) Notwithstanding paragraph (a) of this Section, in the case of Purchase Contracts of any series that obligate the Corporation to sell, and the Holders to purchase, Purchase Contract Property, the Corporation shall not be entitled to sell any Purchase Contract Property or receive any payment of the Purchase Price therefor, if the Corporation fails to deliver such Purchase Contract Property or the cash value thereof (if specified pursuant to Section 3.02) against tender by the Agent of payment therefor.

(c) Unless otherwise specified pursuant to Section 3.02, to be effective, payment with respect to a Purchase Contract pursuant to a Cash Settlement must be deposited with the Agent by 11:00 a.m., New York City time, on the Business Day immediately preceding the Settlement Date and must be made with respect to all (and not fewer than all) of the Purchase Contracts to be settled on such Settlement Date (i) included in the Definitive Units that are registered in the name of the Person effecting Cash Settlement in the Purchase Contract Register, (ii) included in the Global Units that are beneficially owned by the Person effecting Cash Settlement as specified in the records of the direct and indirect participants of the Depositary or (iii) in the case of Purchase Contracts included in Unregistered Definitive Units, owned by the Person effecting Cash Settlement, and, in the case of (ii) and (iii) above, as certified in writing by such Person, which certification shall be collected, in the case of (ii) above, on behalf of such Person by the direct and indirect participants in the Depositary through which such Person holds interests in the Global Units, and which will be provided to the Agent in the case of (iii) above, by such Person or, in the case of (ii) above, by the Depositary or any direct participant of such Depositary, at the time payment pursuant to a Cash Settlement is deposited with the Agent. Any attempted Cash Settlement other than in accordance with this Section 3.06 shall be deemed to have not been made and any payments made to the Agent or by a Holder not complying with this Section 3.06 shall be returned by the Agent to such Holder.

(d) The Corporation shall not be obligated to deliver any Purchase Contract Property (or the cash value thereof) with respect to a Purchase Contract of any series that obligates the Corporation to sell, and the Holder to purchase, Purchase Contract Property unless it shall have received payment in full of the applicable Purchase Price for any Purchase Contract Property to be purchased thereunder in the manner set forth herein or in any Issuer Order relating to the issuance of the Purchase Contracts of such series. The Corporation shall not be obligated to pay the Purchase Price or any other Settlement Amount for any Purchase Contract Property to be purchased by the Corporation pursuant to any Purchase Contract that obligates the Corporation to purchase, and the Holder to sell, Purchase Contract Property unless it shall have received such Purchase Contract Property (or the cash value thereof) or any other Settlement Amount in the manner set forth herein or as specified pursuant to Section 3.02.

(e) In the case of Purchase Contracts that obligate the Corporation to sell, and the Holders to purchase, Purchase Contract Property in each case consisting of securities in registered form, the Agent shall cause such securities deliverable in respect of such Purchase Contracts to be registered, in the case of Registered Units, in the name of the Holder of such Units as set forth in the appropriate Securities Register.

(f) Unless a Holder of a Unit of any series has effected a Cash Settlement in satisfaction of his obligations under any Purchase Contracts constituting a part of such Unit that obligate the Holder, or represent the Holder’s right, to purchase Purchase Contract Property, any payment with respect to principal of any Debt Security evidenced by such Unit that is received by the Agent, Collateral Agent, Trustee or Paying Agent in connection with any Debt Security Settlement shall be paid by the Agent to the Collateral Agent for delivery to the Corporation in satisfaction of the Holder’s obligations under the Global Purchase Contract or Purchase Contracts constituting a part of such Units. Any payment that is received by the Agent, Collateral Agent, Trustee or Paying Agent with respect to interest on a Debt Security related to a Purchase Contract that has been settled in accordance with Section 3.06(a)(ii) shall be distributed to the Holders of Units upon surrender of the appropriate Unit Certificate.

(g) Except as otherwise specified pursuant to Section 3.02, all payments to be made by the Holders or by the Agent, Collateral Agent, Trustee or Paying Agent shall be made in lawful money of the United States of America, by certified check or wire transfer in immediately available funds in accordance with such regulations as the Agent may reasonably establish consistent with the provisions of this Agreement.

(h) Any payment of the applicable Purchase Price deposited by a Holder hereunder with respect to a Purchase Contract shall be held by the Agent in custody for the benefit of the Holder and applied in satisfaction of such Holder’s obligations under such Purchase Contract, or released and delivered to the Holder upon the failure of the Corporation to satisfy its settlement obligations against tender by the Agent of such payment of the applicable Purchase Price.

SECTION 3.07. Delivery of Purchase Contract Property or Other Amounts. Unless otherwise specified pursuant to Section 3.02, (i) in the case of Purchase Contracts obligating the Corporation to sell, and the Holders to purchase, Purchase Contract Property, upon its receipt of payment in full of the Purchase Price for the Purchase Contract Property purchased by any Holder pursuant to the foregoing provisions of this Article, the Corporation shall cause such Purchase Contract Property to be delivered to the Holders; and (ii) in the case of Purchase Contracts obligating the Corporation to purchase, and the Holders to sell, Purchase Contract Property, upon its receipt of the Purchase Contract Property, Settlement Amount or other amount, the Corporation shall cause the Purchase Price, Settlement Amount or other amount, as applicable, to be delivered to the Holders, provided that in each case such delivery shall be made only upon delivery to the Agent of the related Unit Certificate.

Upon receipt of any Unit Certificate, the Agent shall cancel such Unit Certificate in accordance with Section 2.11 as a result of the delivery referred to in the preceding paragraph. If any Debt Securities relating to Closed Purchase Contracts constituting a part of Units evidenced by such Unit Certificate remain outstanding as a result of Cash Settlement, the Corporation shall execute and the Trustee shall authenticate and deliver (i) in the case of Definitive Units, to the Holder thereof, in accordance with the terms of the Indenture, a new certificate or certificates representing solely the principal amount of

Debt Securities still outstanding (ii) in the case of Global Units, if a Global Debt Security not constituting part of a Global Unit has not previously been issued by the Corporation, a second Global Debt Security representing Debt Securities still Outstanding that are not part of Units. If a second Global Debt Security referred to in clause (ii) of the immediately preceding sentence has already been issued, the Agent shall note thereon an appropriate increase in the number of Debt Securities represented by such Global Debt Security.

SECTION 3.08. Charges and Taxes. The Corporation shall not be required to pay any tax or taxes that may be payable with respect to any exchange of or substitution for a Unit Certificate or Security and the Corporation shall not be required to issue or deliver such Unit Certificate or such Security unless or until the Person or Persons requesting the transfer or issuance thereof shall have paid to the Corporation the amount of such tax or shall have established to the satisfaction of the Corporation that such tax has been paid. The Agent shall be under no obligation to pay any such tax.

SECTION 4.01. Acceleration of Obligations. If at any time there shall have occurred an Event of Default with respect to any Debt Securities constituting a part of any Units that has resulted in the principal of any Debt Securities being declared due and payable immediately pursuant to Section 502 of the Indenture, then the Holders of not less than 25% of all Unsettled Purchase Contracts constituting a part of any Units comprising Debt Securities subject to such declaration may on behalf of all Holders of such Unsettled Purchase Contracts by notice in writing to the Corporation and Agent declare the obligations of such Holders to purchase or sell, as the case may be, and of the Corporation to sell or purchase, as the case may be, the quantity of Purchase Contract Property specified pursuant to Section 3.02 under each such Unsettled Purchase Contract to be accelerated to the date of such declaration and, upon any such declaration, such obligations shall be so accelerated. The foregoing provision is subject to the condition that if, at any time prior to settlement of such Purchase Contracts, the declaration with respect to Debt Securities referred to in the immediately preceding sentence and its consequences are rescinded and annulled in accordance with Section 502 of the Indenture, the acceleration of the obligations with respect to Unsettled Purchase Contracts referred to in the immediately preceding sentence and its consequences may be annulled and rescinded by vote of the Holders of not less than 25% of all affected Unsettled Purchase Contracts Outstanding.

SECTION 4.02. Unconditional Rights under Purchase Contracts; Limitation on Proceedings by Holders. (a) The Holder of any Unit shall have the right, which is absolute and unconditional, to purchase or sell, as the case may be, Purchase Contract Property pursuant to such Purchase Contract and to institute suit for the enforcement of such right, and such right shall not be impaired without the consent of such Holder.

(b) No Holder of any Unit shall have any right by virtue of or by availing itself of any provision of this Agreement to institute any action or proceeding at law or in

equity or in bankruptcy or otherwise upon or under or with respect to this Agreement, or for the appointment of a trustee, receiver, liquidator, custodian or other similar official or for any other remedy hereunder, unless such Holder previously shall have given written notice to the Agent and the Corporation of a Default and of the continuance thereof and, (i) in the case of an Event of Default under Debt Securities or the Indenture, the procedures (including notice to the Trustee and the Corporation) described in Article Five of the Indenture have been complied with and (ii) in the case of a Purchase Contract Default specified in clause (ii) of the definition thereof, unless the Holders of not less than 25% of all affected Purchase Contracts comprised by all Units then Outstanding shall have made written request upon the Agent to institute such action or proceedings in its own name as Agent hereunder and shall have offered to the Agent such reasonable indemnity as it may require pursuant to Article Six, and the Agent for 60 days after its receipt of such notice, request and offer of indemnity shall have failed to institute such action or proceedings and no direction inconsistent with such request shall have been given to the Agent in writing by holders of a majority of all affected Purchase Contracts constituting parts of Units then Outstanding. Any Holder of a Unit may then (but only then) seek to enforce the performance of the covenant or agreement with respect to which such Purchase Contract Default exists; it being intended and expressly covenanted by the Holder of each Unit with every other Holder and the Agent that no Holder shall have any right by virtue of or by availing itself of any provision of this Agreement to affect, disturb or prejudice the rights of any other Holder, or to obtain or seek to obtain priority over or preference to any other Holder, or to enforce any right under this Agreement, except in accordance with this Section or the Indenture and for the equal, ratable and common benefit of all Holders. For the protection and enforcement of the provisions of this Section, each and every Holder of a Unit and the Agent shall be entitled to such relief as can be given either at law or in equity.

SECTION 4.03. Restoration of Rights and Remedies. If any Holder of Units has instituted any proceeding to enforce any right or remedy under this Agreement and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to such Holder, then and in every such case, subject to any determination in such proceeding the Corporation, the Agent, the Trustee and such Holder shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies the Corporation, the Agent, the Trustee and such Holder shall continue as though no such proceeding had been instituted.

SECTION 4.04. Rights and Remedies Cumulative. Subject to Section 4.02, and except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Unit Certificates, no right or remedy herein conferred upon or reserved to the Holders of Units is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

SECTION 4.05. Delay or Omission Not Waiver. No delay or omission of any Holder to exercise any right or remedy accruing upon any Default shall impair any such right or remedy or constitute a waiver of any such Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Holders may be exercised from time to time, and as often as may be deemed expedient, by such Holders.

SECTION 4.06. Waiver of Past Defaults. The Holders of not less than a majority of all affected Purchase Contracts evidenced by Units of all series at the time Outstanding may on behalf of the Holders of all affected Units waive any past Purchase Contract Default hereunder and its consequences, except, unless theretofore cured (i) a Purchase Contract Default resulting from the failure of the Corporation to deliver (A) in the case of Purchase Contracts obligating the Corporation to sell, and the Holders to purchase, Purchase Contract Property (or the cash value thereof) Purchase Contract Property (or the cash value thereof) against tender of payment therefor or (B) in the case of Purchase Contracts obligating the Corporation to purchase, and the Holders to sell, Purchase Contract Property (or the cash value thereof) the applicable Purchase Price or other Settlement Amount specified pursuant to Section 3.02 against tender of Purchase Contract Property or other amount specified pursuant to Section 3.02 therefor or (ii) a Purchase Contract Default with respect to a covenant or provision hereof which under Article Seven cannot be modified or amended without approval of the Holder of each affected Purchase Contract that is a part of an Outstanding Unit of any series. In the case of any such waiver, the Holders, the Agent and the Corporation shall be restored to their former positions and rights hereunder, respectively.

Upon any such waiver, such Purchase Contract Default shall cease to exist, for every purpose of this Agreement, but no such waiver shall extend to any subsequent or other Purchase Contract Default or impair any right consequent thereon unless so expressly therein provided.

SECTION 4.07. Undertaking for Costs. All parties to this Agreement agree, and each Holder of any Unit by his acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Agreement, or in any suit against the Agent for any action taken, suffered or omitted by it as Agent, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided that the provisions of this Section shall not apply to any suit instituted by the Agent, to any suit instituted by any Holder of Units, or group of Holders, holding in the aggregate more than 10% of the Outstanding Units, or to any suit instituted by any Holder for enforcement of the right to purchase or sell Purchase Contract Property under the Purchase Contracts constituting a part of the Units held by such Holder or to receive payment of the applicable Purchase Price (or other Settlement Amount that may be specified pursuant to Section 3.02) with respect thereto.

SECTION 4.08. Waiver of Stay or Extension Laws. The Corporation covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Agreement; and the Corporation (to the extent that it may lawfully do so) each hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Agent, or the Holders, but will suffer and permit the execution of every such power as though no such law had been enacted.

SECTION 4.09. Agent May File Proofs of Claims. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy or other judicial proceeding relating to the Corporation or the property of the Corporation or its creditors, the Agent shall be entitled and empowered, by intervention in such proceeding or otherwise,

(i) to file and prove a claim and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Agent, its agents and counsel) and of the Holders allowed in such judicial proceeding; and

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

and any receiver, assignee, trustee, liquidator or other similar official in any such proceeding is hereby authorized by each Holder to make such payments to the Agent, and in the event that the Agent shall consent to the making of such payments directly to the Holders, to pay to the Agent any amount due to it hereunder; provided, however, that nothing herein shall be deemed to authorize the Agent to authorize or consent to or vote for or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Units or the rights of any Holder thereof, or to authorize the Agent to vote in respect of the claim of any Holder of Units in any such proceeding.

SECTION 4.10. Suits for Enforcement. In case a Purchase Contract Default has occurred, has not been waived and is continuing, and subject to receipt by the Agent of the request referred to in Section 4.02 or the direction referred to in Section 4.11 and the security or indemnity referred to in Section 6.03(f), the Agent shall have the right to enforce, on behalf of the Holders, the Purchase Contracts and the covenants and agreements of the Corporation contained in the Purchase Contracts and in this Agreement with respect to the Purchase Contracts and to proceed to protect and enforce such rights by appropriate judicial proceedings to protect and enforce any of such rights, either at law or in equity or in bankruptcy or otherwise, whether for the specific enforcement of any such covenant or agreement contained in this Agreement or in the Purchase Contracts or in aid of the exercise of any power granted in this Agreement or to enforce any other legal or equitable right vested in the Agent by this Agreement or by law.

All rights of action and of asserting claims under this Agreement, or under the Units or any Securities comprised by the Units, may be enforced by the Agent without the possession of the Units or any of the Securities comprised by the Units or the production thereof on any trial or other proceedings relative thereto, and any such actions or proceedings instituted by the Agent shall be brought in its own name as agent and any recovery of judgment, subject to the payment of the expenses, disbursements and compensation of the Agent, each predecessor Agent and their respective agents and attorneys, shall be for the ratable benefit of the Holders of the Units or Securities in respect of which such action was taken.

SECTION 4.11. Control by Holders. The Holders of a majority of affected Outstanding Purchase Contracts constituting a part of any Outstanding Units shall have the right to direct the time, method, and place of conducting any proceeding for any remedy available to the Agent, or exercising any power conferred on the Agent with respect to such Purchase Contracts by this Agreement; provided that such direction shall not be otherwise than in accordance with law and the provisions of this Agreement and provided further that (subject to the provisions of Section 6.01) the Agent shall have the right to decline to follow any such direction if the Agent, being advised by counsel, shall determine that the action or proceeding so directed may not lawfully be taken or if the Agent in good faith by its board of directors or board of trustees or a committee of its Responsible Officers, shall determine that the action or proceedings so directed could involve the Agent in personal liability or if the Agent in good faith shall so determine that the actions or forbearances specified in or pursuant to such direction would be unduly prejudicial to the interests of Holders of Units not joining in the giving of said direction, it being understood that (subject to Section 6.01) the Agent shall have no duty to ascertain whether or not such actions or forbearances are unduly prejudicial to such Holders.

Nothing in this Agreement shall impair the right of the Agent in its discretion (but subject to Section 4.10) to take any action deemed proper by the Agent and which is not inconsistent with such direction or directions by Holders.

SECTION 5.01. Granting of Security Interests; Rights and Remedies of Collateral Agent; Perfection. In order to secure the observance and performance of the covenants and agreements of the Holders of Purchase Contracts contained herein and in such Purchase Contracts, unless otherwise specified pursuant to Section 2.03:

(a) Effective upon issuance of Units of any series consisting of Debt Securities and Purchase Contracts, the Holders thereof acting through the Agent, as their attorney-in-fact, shall be deemed to grant, sell, convey, assign, transfer and pledge unto the Collateral Agent, as agent of and for the benefit of the Corporation, as collateral security for the performance when due by such Holders of their respective obligations hereunder and under the Purchase Contracts constituting a part of such Units, a security interest in and to,

and a lien upon and right of set-off (the “Pledge”) against, all of their right, title and interest in and to (i) the Pledged Items; (ii) all additions to and substitutions for such Pledged Items as may be permissible, if so specified pursuant to Section 3.02; (iii) all income, proceeds and collections received or to be received, or derived or to be derived, now or any time hereafter from or in connection with (i) and (ii) above, and (iv) all powers and rights now owned or hereafter acquired under or with respect to the Pledged Items (such Pledged Items, additions, substitutions, proceeds, collections, powers and rights being herein collectively called the “Collateral”).

(b) Prior to or concurrently with the issuance of Global Units of any series of which Debt Securities and Purchase Contracts constitute a part, the initial Holders and the Agent shall cause the Debt Securities constituting a part of such Global Units to be delivered to the Collateral Agent, and, if specified pursuant to Section 3.02, accompanied by an instrument of transfer executed in blank, and the Corporation shall notify the Collateral Agent of the Pledge and receipt of such notification shall constitute acknowledgment by the Collateral Agent (as third party in possession or otherwise) of the Pledge and its holding of the Collateral subject to the Pledge, in each case for purposes of perfecting the Pledge under applicable law. Subject to the Pledge, the Holders from time to time of the Units of which the Debt Securities constitute a part shall have full beneficial ownership of such Debt Securities.

(c) The Collateral Agent shall have all of the rights, remedies and recourse with respect to the Collateral afforded a secured party by the Uniform Commercial Code as in effect in the State of New York (whether or not said Code is in effect in the jurisdiction where the rights and remedies are asserted), in addition to, and not in limitation of, the other rights, remedies and recourse afforded to the Collateral Agent by this Agreement.

(d) Each Holder, to the extent permitted by applicable law, by accepting Units of any series issued hereunder authorizes the Collateral Agent to execute and file, in the name of such Holder, Uniform Commercial Code financing or continuation statements (which may be carbon, photographic, photostatic or other reproductions of this Agreement or of a financing statement relating to this Agreement) which the Collateral Agent in its sole discretion (but subject to Section 5.03(f)) may deem necessary or appropriate to further perfect, or maintain the perfection of the security interests granted hereby.

SECTION 5.02. Distribution of Principal and Interest; Release of Collateral. Unless otherwise specified pursuant to Section 2.03:

of which such Pledged Items are a part under the Purchase Contracts forming a part of such Units. Any such payments in excess of such obligations of the Holders shall be promptly paid to the Agent to the account designated by it for such purpose. All such payments received by the Agent as provided herein shall be applied by the Agent pursuant to the provisions hereof.

(b) Upon notice to the Collateral Agent by the Agent that one or more Holders of Units have elected to effect Cash Settlement of their respective obligations under the Purchase Contracts forming a part of such Units in accordance with the terms hereof, and that either the Agent has received from such Holders, and paid to the Corporation, the related amounts pursuant to the terms of the Purchase Contracts and this Agreement or no such payment is required, and that all other conditions to such Cash Settlement have been satisfied, then the Collateral Agent shall release from the Pledge the Pledged Items relating to such Purchase Contracts.

(a) The Collateral Agent undertakes to perform such duties and only such duties as are specifically set forth in this Agreement. No provision of this Agreement shall be construed to relieve the Collateral Agent from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that

(b) The Collateral Agent shall not be liable for any error of judgment made in good faith by a Responsible Officer of the Collateral Agent, unless it shall be proved that the Collateral Agent was negligent in ascertaining the pertinent facts.

(c) No provision of this Agreement shall require the Collateral Agent to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

(d) Whether or not therein expressly so provided, every provision of this Agreement relating to the conduct or affecting the liability of or affording protection to the Collateral Agent shall be subject to the provisions of this Section.

(e) The Collateral Agent is acting solely as agent for the Corporation hereunder and owes no fiduciary duties to any Person by virtue of this Agreement.

(f) Except as specifically provided herein, the Collateral Agent shall not be responsible for the validity, sufficiency, collectibility or marketability of any Collateral given to or held by it hereunder or for the validity or sufficiency of the lien on the Collateral purported to be created hereby and shall have no obligation to file any financing or continuation statement with respect to the Collateral in any public office at any time or time.

SECTION 5.04. Knowledge of the Collateral Agent. The Collateral Agent shall not be deemed to have knowledge of any default by any person under any Purchase Contract, unless and until a Responsible Officer of the Collateral Agent assigned to its Corporate Trustee Administration Department shall have actual knowledge thereof or shall have received written notice thereof from the Corporation or any Holder.

SECTION 5.05. Certain Rights of Collateral Agent. Subject to the provisions of Section 5.03:

(a) the Collateral Agent may rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, coupon, security or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties;

(b) any request, direction, order or demand of the Corporation mentioned herein shall be sufficiently evidenced by an Officers’ Certificate, Issuer Order or Issuer Request, and any resolution of the Board of Directors of the Corporation, as the case may be, may be sufficiently evidenced by a Board Resolution;

report, notice, request, consent, order, approval, appraisal, bond, debenture, note, coupon, security or other paper or document;

The obligations of the Corporation under this Section to compensate and indemnify the Collateral Agent and any predecessor Collateral Agent and to pay or reimburse the Collateral Agent and any predecessor Collateral Agent for expenses, disbursements and advances shall constitute additional indebtedness hereunder and shall survive the resignation or removal of such Collateral Agent or predecessor Collateral Agent or the termination hereof or of any Purchase Contract. Such additional indebtedness shall be a senior claim to that of the Units upon all property and funds held or collected by the Collateral Agent as such, except funds held in trust for the benefit of the Holders of Units, and the Units are hereby subordinated to such senior claim.

SECTION 5.07. Corporate Collateral Agent Required Eligibility. There shall at all times be a Collateral Agent hereunder which shall be a corporation organized and doing

business under the laws of the United States of America, any State thereof or the District of Columbia, having, together with its parent, a combined capital and surplus of at least $50,000,000, subject to supervision or examination by Federal, State or District of Columbia authority and willing to act on reasonable terms. If such corporation, or its parent, publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. [**The Collateral Agent hereunder shall at all times be the Agent hereunder and the Trustee and a Paying Agent under the Indenture, subject to receipt of an Opinion of Counsel that the same Person is not precluded by law from acting in such capacities.] If at any time the Collateral Agent shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article. The Collateral Agent may appoint one or more sub-collateral agents with offices or agencies in a city or cities outside the United States.

SECTION 5.08. Resignation and Removal; Appointment of Successor.

The Collateral Agent may be removed at any time upon 60 days’ notice by the filing with it of an instrument in writing signed on behalf of the Corporation and specifying such removal and the date when it is intended to become effective. If the instrument of acceptance by a successor Collateral Agent required by Section 5.09 shall not have been delivered to the Collateral Agent within 30 days after the giving of such notice of resignation, the resigning Collateral Agent may petition any court of competent jurisdiction for the appointment of a successor Collateral Agent.

(i) the Collateral Agent shall cease to be eligible under Section 5.07, [**or shall cease to be eligible as Agent hereunder or as Trustee under the Indenture] and shall fail to resign after written request therefor by the Corporation, or

(ii) the Collateral Agent shall become incapable of acting with respect to the Collateral or shall be adjudged a bankrupt or insolvent, or a receiver or liquidator of the Collateral Agent or of its property shall be appointed or any public officer shall take charge or control of the Collateral Agent or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, then, in any such case, the Corporation, by Board

Resolution, may remove the Collateral Agent and appoint a successor Collateral Agent.

(d) If the Collateral Agent shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Collateral Agent for any cause, the Corporation, by Board Resolution, shall promptly appoint a successor Collateral Agent or Collateral Agents (other than the Corporation) and shall comply with the applicable requirements of Section 5.09.

(e) The Corporation shall give, or shall cause such successor Collateral Agent to give, notice of each resignation and each removal of the Collateral Agent and each appointment of a successor Collateral Agent to all Holders of Units in accordance with Section 11.06. Each notice shall include the name of the successor Collateral Agent and the address of its Corporate Trust Office.

SECTION 5.09. Acceptance of Appointment by Successor. (a) In case of the appointment hereunder of a successor Collateral Agent, every such successor Collateral Agent so appointed shall execute, acknowledge and deliver to the Corporation and to the retiring Collateral Agent an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Collateral Agent shall become effective and such successor Collateral Agent, without any further act, deed or conveyance, shall become vested with all the rights, powers, agencies and duties of the retiring Collateral Agent, with like effect as if originally named as Collateral Agent hereunder; but, on the request of the Corporation or the successor Collateral Agent, such retiring Collateral Agent shall, upon payment of all amounts due and payable to it pursuant to Section 5.06, execute and deliver an instrument transferring to such successor Collateral Agent all the rights and powers of the retiring Collateral Agent and shall duly assign, transfer and deliver to such successor Collateral Agent all property and money held by such retiring Collateral Agent hereunder. Any retiring Collateral Agent shall, nonetheless, retain a prior claim upon all property or funds held or collected by such Collateral Agent to secure any amounts then due it pursuant to Section 5.06.

(b) Upon request of any such successor Collateral Agent, the Corporation shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Collateral Agent all such rights, powers and agencies referred to in paragraph (a) of this Section.

(c) No successor Collateral Agent shall accept its appointment unless at the time of such acceptance such successor Collateral Agent shall be eligible under this Article.

(d) Upon acceptance of appointment by any successor Collateral Agent as provided in this Section, the Corporation shall give notice thereof to the Holders of Units in accordance with Section 11.06. If the acceptance of appointment is substantially contemporaneous with the resignation of the Collateral Agent, then the notice called for by the preceding sentence may be combined with the notice called for by Section 5.08. If the Corporation fails to give such notice within ten days after acceptance of appointment by the

successor Collateral Agent, the successor Collateral Agent shall cause such notice to be given at the expense of the Corporation.

SECTION 5.10. Merger, Conversion, Consolidation or Succession to Business. Any corporation into which the Collateral Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Collateral Agent shall be a party, or any corporation succeeding to all or substantially all the agency business of the Collateral Agent, shall be the successor of the Collateral Agent hereunder, without the execution or filing of any paper or any further act on the part of any of the parties hereto, provided that such corporation shall be otherwise eligible under this Article.

SECTION 5.11. Money Held in Trust. Money held by the Collateral Agent in trust hereunder need not be segregated from other funds held by the Collateral Agent, except to the extent required by law. The Collateral Agent shall be under no obligation to invest or pay interest on any money received by it hereunder, except as otherwise agreed with the Corporation. Any interest accrued on funds deposited with the Collateral Agent or any Paying Agent under this Agreement shall be paid to the Corporation from time to time and the Holders of Units (whether or not any Purchase Contracts are to be redeemed with such funds) shall have no claim to any such interest.

SECTION 6.01. Certain Duties and Responsibilities. (a) The Agent undertakes to perform such duties and only such duties as are specifically set forth in this Agreement.

(b) No provision of this Agreement shall be construed to relieve the Agent from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that

(ii) in the absence of bad faith on its part, the Agent may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any statements, certificates or opinions furnished to the Agent and conforming to the requirements of this Agreement, but in the case of any such statements, certificates or opinions that by any provision hereof are specifically required to be furnished to the Agent, the

Agent shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Agreement.

(c) The Agent shall not be liable for any error of judgment made in good faith by a Responsible Officer of the Agent, unless it shall be proved that the Agent was negligent in ascertaining the pertinent facts.

(d) The Agent shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the Holders of a majority in number of affected Outstanding Purchase Contracts relating to the time, method and place of conducting any proceeding for any remedy available to the Agent, or exercising any power conferred upon the Agent, under this Agreement.

(e) No provision of this Agreement shall require the Agent to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

(f) Whether or not therein expressly so provided, every provision of this Agreement relating to the conduct or affecting the liability of or affording protection to the Agent shall be subject to the provisions of this Section.

(g) The Agent is acting solely as agent for the Corporation hereunder and owes no fiduciary duties to any person by virtue of this Agreement.

SECTION 6.02. Notice of Default. Within 90 days after the occurrence of any Purchase Contract Default of which a Responsible Officer of the Agent assigned to its Corporate Trustee Administration Department has actual knowledge (and except with respect to a Purchase Contract Default under the Purchase Contracts existing on the Settlement Date, in which event, as promptly as practicable thereafter) the Agent shall provide to all Holders of Units, in the manner provided in Section 11.06, notice of such Purchase Contract Default hereunder, unless such Purchase Contract Default shall have been cured or waived.

SECTION 6.03. Certain Rights of Agent. Subject to the provisions of Section 6.01:

(d) the Agent shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, approval, appraisal, bond, debenture, note, coupon, security or other paper or document, but the Agent, in its discretion, may make reasonable further inquiry or investigation into such facts or matters related to the issuance of the Debt Securities and the execution, delivery and performance of the Purchase Contracts as it may see fit, and, if the Agent shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Corporation, at reasonable times during normal business hours, personally or by agent or attorney;

(e) the Agent may execute any of the powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys and the Agent shall not be responsible for any misconduct or negligence on the part of any such agent or attorney appointed with due care by it hereunder;

(f) the Agent shall be under no obligation to exercise any of the rights or powers vested in it by this Agreement at the request, order or direction of any of the Holders pursuant to this Agreement, unless such Holders shall have offered to the Agent reasonable security or indemnity against the costs, expenses and liabilities that might be incurred by it in compliance with such request or direction;

(g) the Agent shall not be liable for any action taken or omitted by it in good faith and believed by it to be authorized or within the discretion, rights or powers conferred upon it by this Agreement; and

SECTION 6.04. Not Responsible for Recitals or Issuance of Units. The recitals contained herein, in the Indenture and in the Units, except the Trustee’s and Agent’s certificates of authentication or countersignature, shall be taken as the statements of the Corporation, and none of the Trustee, Agent or any Authenticating Agent assumes any responsibility for their correctness. The Agent makes no representations as to the validity or sufficiency of this Agreement or of the Units. None of the Trustee, Agent or any Authenticating Agent shall be accountable for the use or application by the Corporation of the proceeds with respect to Units or be responsible for exercising any remedy hereunder on behalf of the Holders, except as expressly provided in this Agreement.

SECTION 6.05. May Hold Units. The Agent, the Collateral Agent, the Trustee, any Authenticating Agent, any Purchase Contract Registrar or any other agent of the Corporation, the Trustee or the Agent, in its individual or any other capacity, may become the owner or pledgee of Units and may otherwise deal with the Corporation and receive, collect, hold and retain collections from the Corporation with the same rights it would have if it were not Authenticating Agent, Purchase Contract Registrar or such other agent, the Trustee, the Collateral Agent or the Agent.

SECTION 6.06. Money Held in Trust. Money held by the Agent in trust hereunder need not be segregated from other funds held by the Agent, except to the extent required by law. The Agent shall be under no obligation to invest or pay interest on any money received by it hereunder, except as otherwise agreed with the Corporation.

The obligations of the Corporation under this Section to compensate and indemnify the Agent and any predecessor Agent and to pay or reimburse the Agent and any predecessor Agent for expenses, disbursements and advances shall constitute additional indebtedness hereunder and shall survive the resignation or removal of such Agent or predecessor Agent or the termination hereof or any Purchase Contract. Such additional indebtedness shall be a senior claim to that of the Units upon all property and funds held or collected by the Agent as such, except funds held in trust for the benefit of the Holders of particular Units, and the Units are hereby subordinated to such senior claim.

SECTION 6.08. Corporate Agent Required: Eligibility. There shall at all times be an Agent hereunder which shall be a corporation organized and doing business under the laws of the United States of America, any State thereof or the District of Columbia, having, together with its parent, a combined capital and surplus of at least $50,000,000, subject to supervision or examination by Federal, State or District of Columbia authority and willing to act on reasonable terms. If such corporation, or its parent, publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. [**The Agent hereunder shall at all times be the Collateral Agent hereunder and the Trustee under the Indenture, subject to receipt of an Opinion of Counsel that the same Person is not precluded by law from acting in such capacities.] If at any time the Agent shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article. The Agent may appoint one or more sub-agents with offices or agencies in a city or cities outside the United States.

SECTION 6.09. Resignation and Removal: Appointment of Successor. (a) No resignation or removal of the Agent and no appointment of a successor Agent pursuant to this Article shall become effective until the acceptance of appointment by the successor Agent in accordance with the applicable requirements of Section 6.10.

(b) The Agent may resign by giving written notice thereof to the Corporation and the Holders, in accordance with Section 11.05 and Section 11.06, 60 days prior to the effective date of such resignation. The Agent may be removed at any time upon 60 days’ notice by the filing with it of an instrument in writing signed on behalf of the Corporation and specifying such removal and the date when it is intended to become effective. If the instrument of acceptance by a successor Agent required by Section 6.10 shall not have been delivered to the Agent within 30 days after the giving of such notice of resignation, the resigning Agent may petition any court of competent jurisdiction for the appointment of a successor Agent.

(i) the Agent shall cease to be eligible under Section 6.08, [**or shall cease to be eligible as Collateral Agent hereunder or as Trustee under the Indenture,] and shall fail to resign after written request therefor by the Corporation or by any Holder, or

(ii) the Agent shall become incapable of acting with respect to the Units or shall be adjudged a bankrupt or insolvent, or a receiver or liquidator of the Agent or of its property shall be appointed or any public officer shall take charge or control of the Agent or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, then, in any such case, (A) the Corporation, by Board Resolution, may remove the Agent and appoint a

successor Agent, or (B) any Holder who has been a bona fide Holder of a Unit for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Agent and the appointment of a successor Agent or Agents. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Agent and appoint a successor Agent.

(d) If the Agent shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Agent for any cause, the Corporation, by Board Resolution, shall promptly appoint a successor Agent or Agents (other than the Corporation) and shall comply with the applicable requirements of Section 6.10. If no successor Agent shall have been so appointed by the Corporation and accepted appointment in the manner required by Section 6.10, any Holder who has been a bona fide Holder of a Unit for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Agent.

(e) The Corporation shall give, or shall cause such successor Agent to give, notice of each resignation and each removal of the Agent and each appointment of a successor Agent to all Holders of Units in accordance with Section 11.06. Each notice shall include the name of the successor Agent and the address of its Corporate Trust Office.

SECTION 6.10. Acceptance of Appointment by Successor. (a) In case of the appointment hereunder of a successor Agent, every such successor Agent so appointed shall execute, acknowledge and deliver to the Corporation and to the retiring Agent an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Agent shall become effective and such successor Agent, without any further act, deed or conveyance, shall become vested with all the rights, powers, agencies and duties of the retiring Agent, with like effect as if originally named as Agent hereunder; but, on the request of the Corporation or the successor Agent, such retiring Agent shall, upon payment of all amounts due and payable to it pursuant to Section 6.07, execute and deliver an instrument transferring to such successor Agent all the rights and powers of the retiring Agent and shall duly assign, transfer and deliver to such successor Agent all property and money held by such retiring Agent hereunder. Any retiring Agent shall, nonetheless, retain a prior claim upon all property or funds held or collected by such Agent to secure any amounts then due it pursuant to Section 6.07.

(b) Upon request of any such successor Agent, the Corporation shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Agent all such rights, powers and agencies referred to in paragraph (a) of this Section.

(c) No successor Agent shall accept its appointment unless at the time of such acceptance such successor Agent shall be eligible under this Article.

(d) Upon acceptance of appointment by any successor Agent as provided in this Section, the Corporation shall give notice thereof to the Holders of Units in

accordance with Section 11.06. If the acceptance of appointment is substantially contemporaneous with the resignation of the Agent, then the notice called for by the preceding sentence may be combined with the notice called for by Section 6.09. If the Corporation fails to give such notice within ten days after acceptance of appointment by the successor Agent, the successor Agent shall cause such notice to be given at the expense of the Corporation.

SECTION 6.11. Merger, Conversion, Consolidation or Succession to Business. Any corporation into which the Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Agent shall be a party, or any corporation succeeding to all or substantially all the agency business of the Agent, shall be the successor of the Agent hereunder, without the execution or filing of any paper or any further act on the part of any of the parties hereto, provided that such corporation shall be otherwise eligible under this Article. In case any Purchase Contracts shall have been countersigned and executed, but not delivered, by the Agent then in office, any successor by merger, conversion or consolidation to such Agent may adopt such countersignature and execution and deliver the Purchase Contracts so countersigned and executed with the same effect as if such successor Agent had itself countersigned and executed such Purchase Contracts.

SECTION 6.12. Appointment of Authenticating Agent. At any time when any of the Units remain Outstanding the Agent may, by an instrument in writing, appoint an Authenticating Agent or Agents with respect to the Purchase Contracts to be authorized to act on behalf of the Agent to countersign, execute and deliver the Purchase Contracts issued upon exchange, registration of transfer or pursuant to Section 2.09 and Purchase Contracts so countersigned, executed and delivered shall be entitled to the benefits of this Agreement and shall be valid and obligatory for all purposes as if countersigned by the Agent hereunder. Wherever reference is made in this Agreement to the countersignature, execution and delivery of Purchase Contracts by the Agent or the Agent’s countersignature or execution, such references shall be deemed to include countersignature, execution and delivery on behalf of the Agent by an Authenticating Agent and a countersignature and execution executed on behalf of the Agent by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Corporation and shall at all times be a corporation organized and doing business under the laws of the United States of America, any State thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent, subject to supervision or examination by Federal or State or District of Columbia authority and having, together with its parent, a combined capital and surplus of not less than $50,000,000. If such Authenticating Agent, or its parent, publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section. The Agent may also

appoint one or more Authenticating Agents with offices or agencies in a city or cities outside the United States.

Any corporation into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to all or substantially all the agency business of an Authenticating Agent, shall continue to be an Authenticating Agent, without the execution or filing of any paper or any further act on the part of the Agent or the Authenticating Agent, provided that such corporation shall be otherwise eligible under this Section.

An Authenticating Agent may resign at any time by giving written notice thereof to the Agent and to the Corporation. The Agent may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Corporation. Upon receiving such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Agent may appoint a successor Authenticating Agent which shall be acceptable to the Corporation and shall provide written notice of such appointment to all Holders of Units in the manner and to the extent provided in Section 11.06. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section. No Authenticating Agent shall have any responsibility or liability for any action taken by it as such at the direction of the Agent.

The provisions of Sections 2.10, 6.04 and 6.05 shall be applicable to each Authenticating Agent.

Pursuant to each appointment made under this Section, the Purchase Contracts covered by such appointment may have endorsed thereon, in addition to the form of Agent’s countersignature and execution of the Purchase Contracts evidenced thereby, an alternative countersignature and execution of the Purchase Contracts contained therein in the following forms:

(b) at such other times as the Agent may request in writing, within 30 days after the receipt by the Corporation of any such request, a list of similar form and content as of a date not more than 15 days prior to the time such list is furnished; provided that no such

list need be furnished if the Agent shall be the Purchase Contract Registrar and the registrar under the Indenture.

SECTION 6.14. Preservation of Information; Communications to Holders.

The Agent may destroy any list furnished to it as provided in Section 6.13 upon receipt of a new list so furnished.

(b) If three or more Holders (herein referred to as “applicants”) apply in writing to the Agent, and furnish to the Agent reasonable proof that each such applicant has owned a Unit for a period of at least six months preceding the date of such application, and such application states that the applicants desire to communicate with other Holders with respect to their rights under this Agreement or under the Units and is accompanied by a copy of the form of proxy or other communication that such applicants propose to transmit, then the Agent shall, within five Business Days after the receipt of such application, at its election either (i) afford such applicants access to the information preserved at the time by the Agent in accordance with Section 6.14 (a) or (ii) inform such applicants as to the approximate number of Holders whose names and addresses appear in the information preserved at the time by the Agent, and as to the approximate cost of mailing to such Holders the form of proxy or other communication, if any, specified in such application.

If the Agent shall elect not to afford such applicants access to such information, the Agent shall, upon the written request of such applicants, mail to each Holder whose name and address appears in the information preserved at the time by the Agent, a copy of the form of proxy or other communication that is specified in such application, with reasonable promptness after a tender to the Agent of the material to be mailed and of payment, or provision for payment, of the reasonable expenses of mailing, unless within five days after such tender, the Agent shall mail to such applicants a written statement to the effect that in the opinion of the Agent, such mailing would be contrary to the best interests of the Holders or would be in violation of applicable law. Thereafter, the Agent shall be relieved of any obligation or duty to such applicants with respect to their application.

(c) Every Holder of Units, by his acceptance thereof, agrees with the Corporation and the Agent that neither the Corporation nor the Agent nor any agent of any of them shall be held accountable by reason of the disclosure of any such information as to the names and addresses of the Holders in accordance with Section 6.14(b), regardless of the source from which such information was derived, and that the Agent shall not be held accountable by reason of mailing any material pursuant to a request made under Section 6.14(b).

SECTION 6.15. No Obligation of Holder. Except to the extent otherwise provided in this Agreement, the Agent assumes no obligations and shall not be subject to any

liability under this Agreement or any Purchase Contract with respect to the obligations of the Holder of a Unit thereunder. The Corporation agrees, and each Holder of a Unit Certificate, by his acceptance thereof, shall be deemed to have agreed, that the Agent’s execution of the Purchase Contracts evidenced by the Unit Certificates shall be solely as agent and attorney-in-fact for the Holders, and that the Agent shall have no obligation to perform such Purchase Contracts on behalf of the Holders, except to the extent provided in this Article.

SECTION 6.16. Tax Compliance. (a) The Agent, on its own behalf and on behalf of the Corporation, will comply with all applicable certification, information reporting and withholding (including “backup” withholding) requirements imposed by applicable United States, federal and state tax laws, regulations or administrative practice (i) with respect to payments on, or transfer or redemption of the Debt Securities or the Purchase Contracts or (ii) if specifically instructed by the Corporation, with respect to the issuance, delivery, holding, or exercise of rights (other than by payment, transfer or redemption) under the Debt Securities or the Purchase Contracts. Such compliance shall include, without limitation, the preparation and timely filing of required returns with respect to, and the timely payment of, all amounts required to be withheld to the appropriate taxing authority or its designated agent. The Corporation will provide to the Agent such information as it may reasonably request in order to comply with this Section.

(b) The Agent shall comply with any direction received from the Corporation with respect to the application of such requirements to particular payments or holders or in other particular circumstances, and may for purposes of this Agreement rely on any such direction in accordance with the provisions of Section 6.01(b)(ii) hereof.

(c) The Agent shall maintain all appropriate records documenting compliance with such requirements, and shall make such records available on request at reasonable times during normal business hours to the Corporation or to their authorized representatives duly authorized in writing.

(d) Unless otherwise specified pursuant to Section 2.03, the portion of the issue price of any Units of any series consisting of Debt Securities and Purchase Contracts allocable to such Debt Securities shall equal the principal amount payable at maturity of such Debt Securities. The Corporation and the Holders agree not to file any tax returns, or take a position with any tax authority, that is inconsistent with the characterization of the Debt Securities as debt.

(e) Unless otherwise specified pursuant to Section 2.03, the Corporation by the issuance and sale of any Unit and any Holder of a Unit by his acceptance thereof agree to (in the absence of any applicable administrative ruling or judicial determination to the contrary) treat the Securities that constitute any Unit as separate securities and to file all United States federal, state and local tax returns consistent with the treatment of such Unit as constituted by separate securities.

SECTION 7.02. Supplemental Agreements with Consent of Holders. With the consent of the Holders of not less than a majority of all Unsettled Purchase Contracts constituting a part of any series of Units Outstanding, in the case of clause (A) below, and with the consent of the Holders of not less than a majority of all Units Outstanding, in the case of clause (B) below, by Act of said Holders delivered to the Corporation and the Agent, the Corporation, when authorized by a Board Resolution or Officers’ Certificate, the Agent and the Collateral Agent may enter into an agreement or agreements supplemental hereto for the purpose of (A) modifying in any manner the terms of the Purchase Contracts or this Agreement with respect to the Purchase Contracts or the rights of the Holders of Units with respect to the Purchase Contracts or (B) modifying in any manner the other terms of this Agreement or the other rights of Holders of Units; provided, however, that no such supplemental agreement shall (i) without the consent of the Holder of each Outstanding Purchase Contract affected thereby in the case of clauses (1), (2) and (3) below and (ii) without the consent of the Holder of each Unit affected thereby, in the case of clauses (4) and (5) below:

SECTION 7.03. Execution of Supplemental Agreements. In exchange for accepting the additional agencies or duties created by, any supplemental agreement permitted

by this Article or the modifications thereby of the agencies or duties created by this Agreement, each of the Agent and the Collateral Agent shall be entitled to receive and (subject to Sections 6.01 and 5.03, respectively) shall be fully protected in relying upon, an opinion of Counsel stating that the execution of such supplemental agreement is authorized or permitted by this Agreement.

SECTION 8.01. Covenant Not to Merge, Consolidate, Sell or Convey Property Except Under Certain Conditions. The Corporation covenants that it will not merge or consolidate with any other corporation or sell, convey or lease all or substantially all of its assets to any Person, firm or corporation, except that the Corporation may merge or consolidate with, or sell, convey or lease all or substantially all of its assets to, any other corporation, provided that (i) the Corporation shall be the continuing corporation, or the successor corporation (if other than the Corporation) shall be a corporation organized and existing under the laws of the United States of America or a state thereof or the District of Columbia and such corporation shall assume the due and punctual performance and observance of all of the covenants and conditions of this Agreement to be performed by the Corporation by supplemental agreement in form satisfactory to the Agent and the Collateral Agent, executed and delivered to the Agent and the Collateral Agent by such corporation, and (ii) neither the Corporation nor such successor corporation immediately after such merger or consolidation, or such sale, conveyance or lease shall be in default in the performance of any such covenant or condition.

SECTION 8.02. Rights and Duties of Successor Corporation. In case of any such consolidation, merger, sale or conveyance and upon any such assumption by the successor corporation, such successor corporation shall succeed to and be substituted for the Corporation with the same effect as if it had been named herein as the Corporation. Such successor corporation thereupon may cause to be signed, and may issue (subject to the provisions of the Indenture) either in its own name or in the name of Wells Fargo & Company any or all of the Unit Certificates, Debt Securities and Purchase Contracts issuable hereunder which theretofore shall not have been signed by the Corporation and delivered to the Agent; and, upon the order of such successor corporation, instead of the Corporation, and subject to all the terms, conditions and limitations in this Agreement prescribed, the Trustee and the Agent shall authenticate, countersign, execute and deliver, as applicable, any Unit Certificates, Debt Securities and Purchase Contracts that previously shall have been signed and delivered by the officers of the Corporation to the Trustee and the Agent for authentication, execution and countersignature, and any Unit Certificates, Debt Securities and Purchase Contracts evidencing Units which such successor corporation thereafter shall cause to be signed and delivered to the Trustee and the Agent for such purpose. All the Purchase Contracts so issued shall in all respects have the same legal rank and benefit under this Agreement as the Purchase Contracts theretofore or thereafter issued in accordance with the terms of this Agreement as though all of such Purchase Contracts had been issued at the date of the execution hereof.

In case of any such consolidation, merger, sale, conveyance or lease such change in phraseology and form (but not in substance) may be made in the Unit Certificates and Purchase Contracts thereafter to be issued as may be appropriate.

SECTION 8.03. Opinion of Counsel to Agent. The Agent and the Collateral Agent, subject to Sections 6.01 and 6.03 and Sections 5.03 and 5.05, respectively, may receive an Opinion of Counsel as conclusive evidence that any such consolidation, merger, sale, conveyance or lease, and any such assumption, complies with the provisions of this Article.

SECTION 9.01. Performance under Purchase Contracts. The Corporation covenants and agrees for the benefit of the Holders of the Units that it will duly and punctually perform its obligations under the Purchase Contracts in accordance with the terms of the Purchase Contracts and this Agreement.

SECTION 9.02. Maintenance of Office or Agency. So long as Units or Purchase Contracts are authorized for issuance pursuant to this Agreement or are Outstanding hereunder, the Corporation will maintain in the City of Minneapolis, an office or agency where Registered Units may be presented or surrendered for payment or acquisition of Purchase Contract Property or where Purchase Contract Property or other property may be tendered for delivery, where Registered Units may be surrendered for registration of transfer

or exchange and where notices and demands to or upon the Corporation in respect of Units and this Agreement may be served. The Corporation hereby initially designates Wells Fargo Bank Minnesota, N.A. as its office or agency in the City of Minneapolis, for each of said purposes. The Corporation will give prompt written notice to the Agent of the location, and any change in the location, of such office or agency. The Corporation will maintain one or more offices or agencies in a city or cities located outside the United States (including any city in which such an agency is required to be maintained under the rules of any stock exchange on which the Units of such series, or the Securities constituting such Units, are listed) where the Unregistered Units, if any, of each series may be presented or surrendered for payment or acquisition of Purchase Contract Property or where Purchase Contract Property or other property may be tendered for delivery. No payment or delivery of Purchase Contract Property on any Unregistered Unit will be made upon presentation of such Unregistered Unit at an agency of the Corporation within the United States nor will any payment or delivery of Purchase Contract Property be made by transfer to an account in, or by mail to an address in, the United States unless pursuant to applicable United States laws and regulations then in effect such payment can be made without adverse tax consequences to the Corporation. Notwithstanding the foregoing, payments in U.S. dollars of Unregistered Units of any series appertaining thereto which are payable in Dollars may be made at an agency of the Corporation maintained in the City of Minneapolis if such payment in dollars at each agency maintained by the Corporation outside the United States for payment on such Unregistered Units is illegal or is effectively precluded by exchange controls or other similar restrictions. If at any time the Corporation shall fail to maintain any such required office or agency or shall fail to furnish the Agent with the name and address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Agent, and the Corporation hereby appoints the Agent as its agent to receive all such presentations, surrenders, notices and demands.

The Corporation may also from time to time designate one or more other offices or agencies where Debt Securities, Purchase Contracts and Unit Certificates may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Corporation of its obligations to maintain offices or agencies provided for in this Section. The Corporation will give prompt written notice to the Agent of any such designation or rescission and of any change in the location of any such other office or agency.

SECTION 9.03. Money for Payments to Be Held in Trust. Any money or other property deposited with the Agent, in trust for payment with respect to any Unit, remaining unclaimed for two years after such payment has become due and payable shall be paid to the Corporation on request of the Corporation pursuant to an Officers’ Certificate; and the Holder of such Unit shall thereafter, as an unsecured general creditor, look only to the Corporation for payment thereof, and all liability of the Agent with respect to such trust money or other property shall thereupon cease.

In the event that (i) the Corporation has delivered Purchase Contract Property (or the cash value thereof) to the Agent against tender of payment for such Purchase Contract Property (or, in the case of Purchase Contracts calling for the purchase of Purchase Contract Property by the Corporation, the Corporation has tendered payment) and (ii) a Holder of a Unit Certificate fails to present and surrender the appropriate Unit Certificate to the Agent, the Purchase Contract Property or the cash value thereof or the Corporation’s payment for Purchase Contract Property deliverable upon settlement of the Purchase Contracts or evidenced by such Unit Certificate, together with any distributions thereon (and, if an effective Cash Settlement with respect to the obligations under such Purchase Contracts has been made, payments in respect of principal of any Debt Securities that are part of such Units), shall be held by the Agent, in trust, for the benefit of such Holder, until such Unit Certificate is presented and surrendered or such Holder delivers to the Agent, the Trustee, and the Corporation (A) evidence to their satisfaction that such certificate has been destroyed, lost or stolen and (B) such security or indemnity as may be required by them to hold each of them and any agent of any of them harmless. In the event such Unit Certificate is not presented and surrendered or such Holder does not satisfy the applicable conditions specified in the preceding sentence on or prior to the date two years after the date of settlement of the related Purchase Contract any distributions received by the Agent with respect to the Purchase Contract Property delivered in respect of the Unit Certificates shall be paid to the Corporation, on the request of the Corporation pursuant to an Officers’ Certificate, and the Holders of such Unit shall thereafter, as unsecured general creditors, look only to the Corporation for payment thereof and all liability of the Agent with respect to such trust assets shall thereafter cease.

SECTION 9.04. Statements of Officers of the Corporation as to Default. The Corporation will deliver to the Agent, on or before in each year, an Officers’ Certificate stating whether or not to the best knowledge of the signers thereof the Corporation is in default in the performance and observance of any of the terms, provisions and conditions hereof or of any Purchase Contracts, and, if the Corporation shall be in default, specifying all such defaults and the nature and status thereof of which they may have knowledge.

SECTION 10.01. Optional Redemption of Purchase Contracts; Redemption Upon Redemption of Debt Securities. If this Article is specified as applicable pursuant to Section 3.02 in connection with the issuance of the Purchase Contracts of a series, any or all of such Purchase Contracts may be redeemed at the option of the Corporation, or from time to time in part, on such date or dates and at a redemption price per Purchase Contract as shall be specified pursuant to Section 3.02; provided that no redemption shall result in there being more than zero but fewer than the minimum amount of Unsettled Purchase Contracts that may remain Outstanding after such redemption, as specified pursuant to Section 3.02.

Unless otherwise specified pursuant to Section 2.03, in the event that the Corporation shall redeem any Debt Security constituting part of a Unit of any series pursuant to the provisions of the Indenture or such Debt Security, the Corporation shall redeem any Purchase Contract on the redemption date of such related Debt Security.

SECTION 10.02. Notice of Redemption; Partial Redemptions. Unless otherwise specified pursuant to Section 3.02, the Corporation or, upon Issuer Order of the Corporation, the Agent in the name and at the expense of the Corporation, shall give notice of redemption to the Holders of Purchase Contracts in the manner and to the extent provided in Section 11.06, at least 30 days and not more than 60 days prior to the date fixed for redemption. Any notice which is given in the manner herein provided shall be conclusively presumed to have been duly given, whether or not the Holder receives the notice. Failure to give notice by mail, or any defect in the notice to the Holder of any Purchase Contract, shall not affect the validity of the proceedings for the redemption of any other Purchase Contract.

The notice of redemption to each Holder of Registered Purchase Contracts shall specify the number of Registered Purchase Contracts held by such Holder to be redeemed, the date fixed for redemption, the redemption price, the place or places of payment and that payment will be made upon presentation and surrender of Unit Certificates with respect to such Registered Purchase Contracts evidenced by Unit Certificates.

The Corporation’s obligation to provide funds for redemption shall be deemed fulfilled if, on or before 12:00 noon, local time in the place of payment, on the redemption date specified in the notice of redemption given as provided in this Section, the Corporation shall deposit with the Agent or with one or more paying agents an amount of money sufficient to redeem on the redemption date all the Purchase Contracts called for redemption at the appropriate redemption price, together with irrevocable instructions and authorization that such funds be applied to the redemption of the Purchase Contracts called for redemption upon surrender of Unit Certificates representing such Purchase Contracts, properly endorsed and assigned for transfer, in accordance with this Article.

The Corporation will deliver to the Agent at least 15 days prior to the mailing of the notice of redemption an Officers’ Certificate stating the aggregate number of Purchase Contracts to be redeemed on such date and that the Corporation has complied with the provisions of Section 10.01 and of said Purchase Contracts subject to said redemption.

If fewer than all the Purchase Contracts are to be redeemed, the Agent, prior to the mailing of the redemption notice, shall select the Purchase Contracts to be redeemed on a pro rata basis, by lot or by such other means as shall be acceptable to the Agent. Appropriate adjustment shall be made to prevent the fractional redemption of Purchase Contracts, such that Purchase Contracts are redeemed only in whole and not in part.

The Agent shall promptly notify the Corporation in writing of the Purchase Contracts so selected for redemption.

SECTION 10.03. Payment of Purchase Contracts Called for Redemption. If notice of redemption has been given as above provided, (i) the Purchase Contracts specified in such notice shall become due and payable on the date and at the place stated in such notice at the applicable redemption price, and (ii) on and after the date fixed for redemption (unless the Corporation shall default in the payment of such Purchase Contracts at the redemption price) such Purchase Contracts shall cease from and after the date fixed for redemption to be entitled to any benefit under this Agreement, the Holders thereof shall have no right or obligation in respect of such Purchase Contracts except the right to receive the redemption price thereof and the Purchase Contracts shall terminate and shall no longer be deemed to be Outstanding.

If so specified pursuant to Section 3.02, on presentation and surrender of Unit Certificates representing such Purchase Contracts, properly endorsed and assigned for transfer, at a place of payment specified in said notice, said Purchase Contracts shall be paid and redeemed by the Corporation at the applicable redemption price. Following such redemption, the Unit Certificates evidencing such Closed Purchase Contracts shall be cancelled in accordance with Section 2.11. In the case of (i) Definitive Units, certificates evidencing any Outstanding Debt Securities relating to such redeemed Purchase Contracts shall be executed, authenticated and delivered in accordance with the terms of the Indenture and (ii) Global Units, if a Global Debt Security not constituting part of a Global Unit has not previously been issued by the Corporation, a second Global Debenture evidencing any Outstanding Debt Security relating to such redeemed Purchase Contracts shall be executed, authenticated and delivered in accordance with the Indenture. If a second Global Debt Security referred to in clause (ii) of the immediately preceding sentence has already been issued, the Agent shall note thereon an appropriate increase in the number of Debt Securities represented by such Global Debt Security.

Any interest accrued on funds deposited with the Agent or any Paying Agent in connection with this Article Ten shall be paid to the Corporation from time to time and the Holders of Purchase Contracts (whether or not such Purchase Contracts are to be redeemed with such funds) shall have no claim to any such interest. Any funds deposited and unclaimed at the end of two years from any redemption date shall be repaid or released to the Corporation, on the request of the Corporation pursuant to an Officers’ Certificate, after which the Holder(s) of Purchase Contracts so called for redemption shall look only to the Corporation for payment of the redemption price, without any interest thereon and all liability of the Agent with respect to the redemption price shall cease.

SECTION 10.04. Exclusion of Certain Purchase Contracts from Eligibility for Selection for Redemption. Purchase Contracts shall be excluded from eligibility for selection for a partial redemption if they are identified by registration and certificate number in an Officers’ Certificate delivered by the Corporation to the Agent at least 10 days prior to the date of the mailing of a notice of redemption as being owned of record and beneficially by, and not pledged or hypothecated by (a) the Corporation or (b) an Affiliate of the Corporation. Purchase Contracts shall also be excluded from eligibility for selection for a partial redemption if they are the subject of an Acceleration Notice.

SECTION 11.01. Incorporators, Stockholders, Officers and Directors of the Corporation Immune from Liability. No recourse under or upon any obligation, covenant or agreement contained in this Agreement, or in any Debt Security or any Purchase Contract, or because of any indebtedness evidenced thereby, shall be had against any incorporator, or against any past, present or future stockholder, officer, attorney-in-fact or director, as such, of the Corporation or of any successor corporation, either directly or through the Corporation or any successor corporation, under any rule of law, statute or constitutional provision or by the enforcement of any assessment or penalty or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released by the acceptance of the Units by the Holders thereof and as part of the consideration for the issue thereof, provided that nothing in this Article shall impair the obligations, covenants and agreements of the Corporation contained in this Agreement and in any Debt Securities or Purchase Contracts constituting a part of the Units of any series.

SECTION 11.03. Form of Documents Delivered to Agent or Collateral Agent. In any case where several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an opinion with respect to some matters and one or more other such Persons as to other matters, and any such Person may certify or give an opinion as to such matters in one or several documents.

Any certificate, statement or opinion of an officer or counsel of or for the Corporation may be based, insofar as it relates to legal matters, upon a certificate or opinion of, or representations by, counsel, unless such officer knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to the matters upon which his certificate, statement or opinion is based are erroneous. Any such certificate, statement or opinion may be based, insofar as it relates to factual matters, upon a certificate, statement or opinion of, or representations by, an officer or officers of the Corporation, as applicable, stating that the information with respect to such factual matters is in the possession of the Corporation, unless such counsel knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to such matters are erroneous.

Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this Agreement, they may, but need not, be consolidated and form one instrument.

SECTION 11.04. Acts of Holders. (a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Agreement 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 an 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 Agent and, where it is hereby expressly required, to the Corporation. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Agreement and (subject to Section 6.01) conclusive in favor of the Agent and the Corporation, if made in the manner provided in this Section.

(b) The fact and date of the execution by any Person of any such instrument or writing may be proved in any manner that the Agent deems sufficient.

(c) Subject to Section 2.03(a)(vii), the ownership (i) of Registered Units of any series shall be proved by the Purchase Contract Register for such series, with respect to any Purchase Contracts constituting a part of such Units and the Debt Security Register for

such series, with respect to any Debt Securities constituting a part of such Units, and (ii) of Unregistered Units shall be proved by possession of the Unit Certificates evidencing such Units or by the appropriate records of the depositary for such units.

(d) Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Unit Certificate shall bind every future Holder of the same Unit Certificate and the Holder of every Unit Certificate issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof with respect to anything done, omitted or suffered to be done by the Agent or the Corporation in reliance thereon, whether or not notation of such action is made upon such Unit Certificate.

(e) The Corporation may set a record date for purposes of determining the identity of Holders of Units entitled to consent to any action by consent authorized or permitted hereby. Unless otherwise specified pursuant to Section 2.03, such record date shall be the later of 30 days prior to the first solicitation of such consent or the date of the most recent list of Holders of Units furnished to the Agent, pursuant hereto.

SECTION 11.05. Notices, Etc. Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or other document provided or permitted by this Agreement to be made upon, given or furnished to, or filed with,

(b) the Corporation by the Agent, the Collateral Agent or by any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if made, given, furnished or filed in writing and personally delivered or mailed, first-class postage prepaid, addressed to the Corporation at 420 Montgomery Street, San Francisco, California 94104, MAC # A0101-121, Attention: Chief Financial Officer, or at any other address previously furnished in writing to the Agent and the Collateral Agent by the Corporation.

SECTION 11.06. Notices to Holders; Waiver.

In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Where this Agreement provides for notice in any

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

In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification as shall be made with the approval of the Agent shall constitute a sufficient notification for every purpose hereunder.

Where this Agreement provides for notice to Holders of Unregistered Securities or Unregistered Units of any event, such notice shall be sufficiently given (unless otherwise specified herein or pursuant to Section 2.03 or 3.02) by publication in a newspaper in the English language of general circulation in the Borough of Manhattan, The City of New York, and in The City of London or, if publication in London is not practical, in an English language newspaper with general circulation in Western Europe.

SECTION 11.08. Successors and Assigns. All covenants and agreements in this Agreement, the Units, the Purchase Contracts and the Unit Certificates by the Corporation shall bind its successors and assigns, whether so expressed or not.

SECTION 11.09. Separability Clause.

SECTION 11.12. Legal Holidays. Unless otherwise specified pursuant to Section 3.02, in any case where any Settlement Date shall not be a Business Day, then (notwithstanding any other provisions of this Agreement or the Purchase Contracts) the Purchase Contracts shall not be performed on such date, but shall be performed on the next succeeding Business Day with the same force and effect as if performed on such Settlement Date; provided that no interest or other amounts shall accrue or be payable by the Corporation or any Holder for the period from and after any such Settlement Date.

SECTION 11.13. Counterparts. This Agreement may be executed in any number of counterparts by the parties hereto on separate counterparts, each of which, when so executed and delivered, shall be deemed an original, but all such counterparts shall together constitute one and the same instrument.

Any such Calculation Agent shall act as an independent expert and, unless otherwise provided by this Agreement, its calculations and determinations under this Agreement shall, absent manifest error, be final and binding on the Corporation, the Agent and the Holders. Any such calculations will be made available to the Holders for inspection at the Agent’s Office.

(b) Unless otherwise specified pursuant to Section 2.03, the Corporation hereby appoints as the Paying Agent under the Indenture with respect to each Debt Security comprised by any Unit issued hereunder.

SECTION 11.15. Inspection of Agreement. A copy of this Agreement shall be available at all reasonable times during normal business hours at the Corporate Trust Office of the Agent for inspection by any Holder.
