ARTICLE IV

DISTRIBUTIONS; REDEMPTION

4.01. Distributions.

(a) Distributions on the Trust Securities shall be cumulative, and will accumulate whether or not there are funds of the Trust available for the payment of Distributions. Distributions shall accumulate from August 25, 2003 and, except during an Extension Period for the Trust Debt Securities pursuant to the Indenture, shall be payable quarterly in arrears on March 31, June 30, September 30 and December 31 of each year, commencing on September 30, 2003. If any date on which Distributions are otherwise payable on the Trust Securities is not a Business Day, then the payment of such Distributions shall be made on the next succeeding day which is a Business Day (and without any interest or other payment in respect of any such delay), except that, if such Business Day is in the next succeeding calendar year, payment of such Distributions shall be made on the immediately preceding Business Day, in each case with

the same force and effect as if made on such date (each date on which Distributions are payable in accordance with this Section 4.01(a) is referred to as a “Distribution Date”).

Within two Business Days after receipt by the Property Trustee of notice of an Extension Period pursuant to Section 4.01 of the Indenture, the Property Trustee shall give notice thereof to the Securityholders by first class mail, postage prepaid.

The Trust Securities represent undivided beneficial interests in the Trust Property, and, subject to Sections 4.03 and 4.06 hereof, all Distributions will be made pro rata on each of the Trust Securities. Distributions on the Trust Securities shall be payable: (i) on Book-Entry Preferred Trust Securities, in immediately available funds to the Clearing Agency; (ii) on Preferred Trust securities not in book-entry form with the Clearing Agency, by check mailed to the address of the holder thereof; and (iii) on the Common Trust Securities, in any manner specified by the Sponsor. During an Extension Period for the Trust Debt Securities, the rate per annum at which Distributions on the Trust Securities are then accumulating shall be increased by an amount such that the aggregate amount of Distributions that accumulate on all Trust Securities during any such Extension Period is equal to the aggregate amount of interest (including interest payable on unpaid interest at the rate per annum referred to above, compounded quarterly) that accrues during any such Extension Period on the Trust Debt Securities.

(b) Distributions on the Trust Securities shall be made from the Payment Account by the Property Trustee or any Paying Agent and shall be payable on each Distribution Date only to the extent that the Trust has funds then available in the Payment Account for the payment of such Distributions.

(c) Distributions on the Trust Securities on each Distribution Date shall be payable to the Holders thereof as they appear on the Securities Register for the Trust Securities on the relevant record date, which shall be one Business Day prior to such Distribution Date; provided, however, that in the event that the Preferred Trust Securities are not in book-entry-only form, the relevant record date shall be the 15th day preceding such Distribution Date, whether or not a Business Day.

4.02. Redemption.

(a) Upon receipt by the Trust of a notice of redemption of Trust Debt Securities, the Trust will call for redemption a Like Amount of Outstanding Trust Securities on the Trust Debt Security Redemption Date and will call for redemption all Outstanding Trust Securities on the stated maturity date of the Trust Debt Securities, in each case, at the Redemption Price.

(b) Notice of redemption shall be given by the Property Trustee by first-class mail, postage prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption Date to each Holder of Trust Securities to be redeemed, at such Holder’s address appearing in the Securities Register. All notices of redemption shall state:

(i) the Redemption Date;

(ii) the Redemption Price;

(iii) the CUSIP number;

(iv) the place or places where Trust Securities Certificates are to be surrendered for payment of the Redemption Price;

(v) that on the Redemption Date the Redemption Price will become payable upon each such Trust Security to be redeemed and that Distributions thereon will cease to accumulate on and after such date; and

(vi) if less than all of the Outstanding Trust Securities are to be redeemed, the identification and total Liquidation Amount of the particular Trust Securities to be redeemed.

(c) The Trust Securities redeemed on each Redemption Date shall be redeemed at the Redemption Price with the proceeds from the contemporaneous redemption or payment at maturity of Trust Debt Securities. Redemptions of the Trust Securities shall be made and the Redemption Price shall be payable on each Redemption Date only to the extent that the Trust has funds then available in the Payment Account for the payment of such Redemption Price.

(d) If the Trust, by action of the Property Trustee, gives a notice of redemption in respect of any Preferred Trust Securities, then, on the Redemption Date, subject to Section 4.02(c), the Property Trustee will irrevocably deposit with the Paying Agent funds sufficient to pay the Redemption Price for the Preferred Trust Securities being redeemed on such date and will give the Paying Agent irrevocable instructions and authority to pay the Redemption Price to the Holders of such Preferred Trust Securities upon surrender of their Preferred Trust Securities Certificates. Notwithstanding the foregoing, Distributions payable on or prior to the Redemption Date for any Trust Securities called for redemption shall be payable to the Holders of such Trust Securities as they appear on the Securities Register for the Trust Securities on the record dates for the related Distribution Dates. If notice of redemption shall have been given and funds irrevocably deposited as required, then upon the date of such deposit, all rights of Securityholders holding Trust Securities so called for redemption will cease, except the right of such Securityholders to receive the Redemption Price, but without interest, and such Trust Securities will cease to be Outstanding. In the event that any date on which any Redemption Price is payable is not a Business Day, then payment of the Redemption Price payable on such date will be made on the next succeeding day which is a Business Day (and without any interest or other payment in respect of any such delay), except that, if such Business Day is in the next succeeding calendar year, such payment will be made on the immediately preceding Business Day, in each case, with the same force and effect as if made on such date. In the event that payment of the Redemption Price in respect of any Trust Securities called for redemption is improperly withheld or refused, and not paid either by the Trust or by the Sponsor pursuant to the Guarantee, Distributions on such Trust Securities will continue to accumulate, at the then applicable rate, from the Redemption Date originally established by the Trust for such Trust Securities to the date such Redemption Price is actually paid, in which case the actual payment date will be the date fixed for redemption for purposes of calculating the Redemption Price.

(e) If less than all the Outstanding Trust Securities are to be redeemed on a Redemption Date, then the aggregate Liquidation Amount of Trust Securities to be redeemed

shall be allocated to the Common Trust Securities and the Preferred Trust Securities pro rata based on the aggregate Liquidation Amount of each of the Outstanding Common Trust Securities and the Outstanding Preferred Trust Securities in relation to the aggregate Liquidation Amount of all of the Outstanding Trust Securities. The particular Preferred Trust Securities to be redeemed shall be selected by the Property Trustee from the Outstanding Preferred Trust Securities not previously called for redemption, by such method as the Property Trustee shall deem appropriate. The Property Trustee shall promptly notify the Securities Registrar in writing of the Preferred Trust Securities selected for redemption. If fewer than all of the Trust Securities represented by a Trust Securities Certificate are redeemed, the Delaware Trustee shall execute for the Holder a new Trust Securities Certificate representing the unredeemed Trust Securities. For all purposes of this Trust Agreement, unless the context otherwise requires, all provisions relating to the redemption of Preferred Trust Securities shall relate, in the case of any Preferred Trust Securities redeemed or to be redeemed only in part, to the portion of the Liquidation Amount of Preferred Trust Securities which has been or is to be redeemed.

4.03. Subordination of Common Trust Securities.

(a) Payment of Distributions on, and the Liquidation, Distribution and Redemption Price of, the Trust Securities, as applicable, shall be made pro rata based on the Liquidation Amount of the Trust Securities; provided, however, that if on any applicable date, an Event of Default shall have occurred and be continuing, no payment of any Distribution on, or Liquidation, Distribution and Redemption Price of, any Common Trust Security, and no other payment on account of the Common Trust Securities, shall be made unless payment in full in cash of all accumulated and unpaid Distributions on all Outstanding Preferred Trust Securities for all distribution periods terminating on or prior thereto, or in the case of payment of the Liquidation, Distribution and Redemption Price, the full amount of such Liquidation, Distribution and Redemption Price applicable to all Outstanding Preferred Trust Securities then outstanding or then being redeemed, as the case may be, shall have been made or provided for, and all funds immediately available to the Property Trustee shall first be applied to the payment in full in cash of all Distributions on, or the Liquidation, Distribution and Redemption Price of, Preferred Trust Securities then due and payable.

(b) In the case of the occurrence of any Event of Default, the Holder of Common Trust Securities will be deemed to have waived any right to act with respect thereto until the effect thereof has been cured, waived or otherwise eliminated. Until any such Event of Default has been so cured, waived or otherwise eliminated, the Property Trustee shall act solely on behalf of the Holders of the Preferred Trust Securities and not the Holder of the Common Trust Securities, and only the Holders of the Preferred Trust Securities will have the right to direct the Property Trustee to act on their behalf.

4.04. Payment Procedures. Payments of Distributions pursuant to Section 4.01 in respect of the Preferred Trust Securities shall be made by check mailed to the address of the Holder thereof as such address shall appear on the Securities Register or, if the Preferred Trust Securities are held by a Clearing Agency, such Distributions shall be made to the Clearing Agency by wire transfer in immediately available funds. Payments of Distributions pursuant to Section 4.01 in respect of the Common Trust Securities shall be made in such manner as shall be mutually agreed between the Property Trustee and the Holder of the Common Trust Securities.

Payment of the Redemption Price or Liquidation Distribution of the Trust Securities shall be made in immediately available funds upon surrender of the Preferred Trust Securities Certificate representing such Preferred Trust Securities at the Corporate Trust Office of the Property Trustee.

4.05. Tax Returns and Reports. The Depositor shall prepare (or cause to be prepared) and file all Federal, State and local tax and information returns and reports required to be filed by or in respect of the Trust, including the appropriate Internal Revenue Service form, if any, required to be filed in respect of the Trust in each taxable year of the Trust. Notwithstanding the foregoing, the Delaware Trustee shall prepare and furnish (or cause to be prepared and furnished) to each Securityholder the related Internal Revenue Service forms, if any (including a Form 1099 OID, or any successor form, if and to the extent necessary). The Trustees shall comply with United States Federal withholding and backup withholding tax laws and information reporting requirements with respect to any payments to Securityholders under the Trust Securities.

4.06. Payments under Indenture. Any amount payable hereunder to any Holder of Preferred Trust Securities shall be reduced by the amount of any corresponding payment such Holder has directly received pursuant to Section 6.07 of the Indenture or pursuant to the Guarantee. Notwithstanding the provisions hereunder to the contrary, Securityholders acknowledge that any Holder of Preferred Trust Securities that receives payment under Section 6.07 of the Indenture may receive amounts greater than the amount such Holder may be entitled to receive pursuant to the other provisions of this Trust Agreement.

A transferee of a Trust Securities Certificate shall become a Securityholder, and shall be entitled to the rights and subject to the obligations of a Securityholder hereunder, upon due registration of such Trust Securities Certificate in such transferee’s name pursuant to Section 5.04.

5.03. Delivery of Trust Securities Certificates. On the Closing Date, the Delaware Trustee shall cause Trust Securities Certificates, in an aggregate Liquidation Amount as provided

in Sections 2.04 and 2.05, to be executed on behalf of the Trust as provided in Section 5.02 and delivered to or upon a written order of the Sponsor signed by its Chairman of the Board, its Chief Executive Officer, any Vice President or the Chief Financial Officer, without further corporate action by the Sponsor, in authorized denominations. The written order of the Sponsor shall be accompanied by an Officers’ Certificate and an Opinion of Counsel.

5.04. Registration of Transfer and Exchange of Preferred Trust Securities Certificates. A registrar appointed by the Sponsor (the “Securities Registrar”) shall keep or cause to be kept, at the office or agency maintained pursuant to Section 5.08, a register (the “Securities Register”) in which, subject to such reasonable regulations as it may prescribe, the Securities Registrar shall provide for the registration of Trust Securities Certificates (subject to Section 5.10 in the case of the Common Trust Securities Certificates) and registration of transfers and exchanges of Preferred Trust Securities Certificates as herein provided. The Property Trustee shall be the initial Securities Registrar; any successor Securities Registrar shall be appointed by the Delaware Trustee.

Upon surrender for registration of transfer of any Preferred Trust Securities Certificate at the office or agency maintained pursuant to Section 5.08, the Delaware Trustee shall execute and deliver, in the name of the designated transferee or transferees, one or more new Preferred Trust Securities Certificates representing the same number of Preferred Trust Securities dated the date of execution by the Delaware Trustee. At the option of a Holder, Preferred Trust Securities Certificates may be exchanged for other Preferred Trust Securities Certificates upon surrender of the Preferred Trust Securities Certificates to be exchanged at the office or agency maintained pursuant to Section 5.08. The Securities Registrar shall not be required to register the transfer of any Preferred Trust Securities that have been called for redemption or after the Liquidation Date.

Preferred Trust Securities presented or surrendered for registration of transfer or exchange shall be accompanied by a written instrument of transfer in form satisfactory to the Delaware Trustee and the Securities Registrar duly executed by the Holder or such Holder’s attorney duly authorized in writing. Each Preferred Trust Securities Certificate surrendered for registration of transfer or exchange shall be cancelled and subsequently disposed of by the Property Trustee in accordance with its customary practice.

No service charge shall be made for any registration of transfer or exchange of Preferred Trust Securities, but the Securities Registrar may require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any transfer or exchange of Preferred Trust Securities other than an exchange not involving any transfer.

5.05. Mutilated, Destroyed, Lost or Stolen Trust Securities Certificates. If (a) any mutilated Trust Securities Certificate shall be surrendered to the Securities Registrar, or if the Securities Registrar shall receive evidence to its satisfaction of the destruction, loss or theft of any Trust Securities Certificate, and (b) there shall be delivered to the Securities Registrar and the Delaware Trustee such security or indemnity as may be reasonably required by them to hold the Securities Registrar and the Trust harmless, then in the absence of notice that such Trust Securities Certificate shall have been acquired by a protected purchaser, the Delaware Trustee, on behalf of the Trust shall execute and make available for delivery, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Trust Securities

Certificate, a new Trust Securities Certificate of like tenor. In connection with the issuance of any new Trust Securities Certificate under this Section, the Delaware Trustee or the Securities Registrar may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection therewith. Any duplicate Trust Securities Certificate issued pursuant to this Section shall constitute conclusive evidence of an undivided beneficial interest in the assets of the Trust, as if originally issued, whether or not the lost, stolen or destroyed Trust Securities Certificate shall be found at any time.

5.06. Persons Deemed Securityholders. Prior to due presentation of a Trust Security Certificate for registration of transfer, the Delaware Trustee or the Securities Registrar shall treat the Person in whose name any Trust Securities Certificate shall be registered in the Securities Register as the owner and Holder of such Trust Securities Certificate for the purpose of receiving Distributions and for all other purposes whatsoever, and neither the Trustees nor the Securities Registrar shall be bound by any notice to the contrary.

5.07. Access to List of Securityholders’ Names and Addresses. In the event that the Property Trustee is no longer the Securities Registrar, the Delaware Trustee or the Sponsor shall furnish or cause to be furnished (a) to the Property Trustee, quarterly not later than 10 days prior to a Distribution Date, a list, in such form as the Property Trustee may reasonably require, of the names and addresses of the Securityholders as of the most recent record date and (b) to the Property Trustee, promptly after receipt by the Delaware Trustee or the Sponsor of a request therefor from the Property Trustee in order to enable the Paying Agent to pay Distributions in accordance with Section 4.01 hereof), in each case to the extent such information is in the possession or control of the Delaware Trustee or the Sponsor and is not identical to a previously supplied list or has not otherwise been received by the Property Trustee. The rights of Securityholders to communicate with other Securityholders with respect to their rights under this Trust Agreement or under the Trust Securities, and the corresponding rights of the Property Trustee shall be as provided in the Trust Indenture Act. Each Holder, by receiving and holding a Trust Securities Certificate, shall be deemed to have agreed not to hold the Sponsor, the Property Trustee or the Delaware Trustee accountable by reason of the disclosure of its name and address, regardless of the source from which such information was derived.

5.08. Maintenance of Office or Agency. The Property Trustee shall maintain in Chicago, Illinois, an office or offices or agency or agencies where Preferred Trust Securities may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Trustees in respect of the Trust Securities Certificates may be served. The Property Trustee shall give prompt written notice to the Sponsor and to the Securityholders of any change in the location of the Securities Register or any such office or agency, which shall initially be at the Corporate Trust Office of the Property Trustee.

5.09. Appointment of Paying Agent. The Paying Agent shall make Distributions to Securityholders from the Payment Account and shall report the amounts of such Distributions to the Property Trustee and the Delaware Trustee. Any Paying Agent shall have the revocable power to withdraw funds from the Payment Account for the purpose of making Distributions. The Delaware Trustee may revoke such power and remove the Paying Agent, provided that such revocation and removal with respect to the sole Paying Agent shall not become effective until the appointment of a successor. The Paying Agent shall initially be the Property Trustee, and any

co-paying agent chosen by the Property Trustee and acceptable to the Delaware Trustee and the Sponsor. Any Person acting as Paying Agent shall be permitted to resign as Paying Agent upon 30 days’ written notice to the Delaware Trustee and the Sponsor, and, if applicable, the Property Trustee, provided that such resignation with respect to the sole Paying Agent shall not become effective until the appointment of a successor. In the event that the Property Trustee shall no longer be the Paying Agent or a successor Paying Agent shall resign or its authority to act be revoked, the Delaware Trustee shall appoint a successor that is acceptable to the Property Trustee (in the case of any other Paying Agent) and the Sponsor to act as Paying Agent (which shall be a bank or trust company and have a combined capital and surplus of at least $50,000,000). The Delaware Trustee shall cause such successor Paying Agent or any additional Paying Agent appointed by the Delaware Trustee to execute and deliver to the Trustees an instrument in which such successor Paying Agent or additional Paying Agent shall agree with the Trustees that as Paying Agent, such successor Paying Agent or additional Paying Agent will hold all sums, if any, held by it for payment to the Securityholders in trust for the benefit of the Securityholders entitled thereto until such sums shall be paid to such Securityholders. The Paying Agent shall return all of such sums remaining unclaimed to the Property Trustee and upon removal of a Paying Agent such Paying Agent shall also return such sums in its possession to the Property Trustee. The provisions of Sections 7.01, 7.03 and 7.06 shall apply to the Property Trustee also in its role as Paying Agent, for so long as the Property Trustee shall act as Paying Agent and, to the extent applicable, to any other Paying Agent appointed hereunder. Any reference in this Trust Agreement to the Paying Agent shall include any co-paying agent unless the context requires otherwise.

5.10. No Transfer of Common Trust Securities by Sponsor. To the fullest extent permitted by law, any attempted transfer of the Common Trust Securities shall be void. The Trustee shall cause each Common Trust Securities Certificate issued to the Sponsor to contain a legend stating “TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, THIS CERTIFICATE, AND THE COMMON TRUST SECURITIES REPRESENTED HEREBY, ARE NOT TRANSFERABLE”. By execution of this Trust Agreement, the Sponsor agrees to the foregoing provisions.

5.11. Book-Entry Preferred Trust Securities Certificates; Common Trust Securities Certificate.

(a) The Preferred Trust Securities, upon original issuance on the Closing Date, will not be engraved but will be issued in the form of one or more printed or typewritten Book-Entry Preferred Trust Securities Certificates, to be delivered to The Depository Trust Company, the initial Clearing Agency, by, or on behalf of, the Trust. Such Book-Entry Preferred Trust Securities Certificate or Certificates shall initially be registered on the Securities Register in the name of Cede & Co., the nominee of the initial Clearing Agency.

(b) A single Common Trust Securities Certificate representing the Common Trust Securities shall be issued to the Sponsor in the form of a definitive Common Trust Securities Certificate.

5.12. Definitive Preferred Trust Securities Certificates. If (a) the Sponsor advises the Trustees in writing that the Clearing Agency is no longer willing or able to properly

discharge its responsibilities with respect to the Preferred Trust Securities Certificates or the Clearing Agency is no longer registered or in good standing under the Securities Exchange Act of 1934, as amended, or other applicable statute or regulation, and the Sponsor is unable to locate a qualified successor within 60 calendar days, (b) the Sponsor, in its sole discretion, advises the Trustees in writing that it elects to terminate the book-entry system through the Clearing Agency or (c) an Event of Default occurs and is continuing, then the Trustee shall issue Definitive Preferred Trust Securities Certificates. Upon surrender to the Trustee of the Book-Entry Preferred Trust Securities Certificates by the Clearing Agency, accompanied by registration instructions, the Trustee shall execute and deliver the Definitive Preferred Trust Securities Certificates in accordance with the instructions of the Clearing Agency. Neither the Securities Registrar nor the Trustees shall be liable for any delay in delivery of such instructions and may conclusively rely on, and shall be protected in relying on, such instructions. The Definitive Preferred Trust Securities Certificates shall be printed, lithographed or engraved or may be produced in any other manner as is reasonably acceptable to the Trustee, as evidenced by the execution thereof by the Trustee.

5.13. Rights of Securityholders. The Securityholders shall not have any right or title to the Trust Property other than the undivided beneficial interest in the assets of the Trust conferred by their Trust Securities and they shall have no right to call for any partition or division of property, profits or rights of the Trust except as described below. The Trust Securities shall be personal property giving only the rights specifically set forth therein and in this Trust Agreement. The Preferred Trust Securities shall have no preemptive or similar rights and when issued and delivered to Securityholders against payment of the purchase price therefor will be fully paid and nonassessable by the Trust. The Holders of the Preferred Trust Securities, in their capacities as such, shall be entitled to the same limitation of personal liability extended to stockholders of private corporations for profit organized under the General Corporation Law of the State of Delaware.

ARTICLE VI

ACTS OF SECURITYHOLDERS; MEETINGS; VOTING

6.01. Limitations on Voting Rights.

(a) Except as provided herein and in the Indenture and as otherwise required by law, no Holder of Trust Securities shall have any right to vote or in any manner otherwise control the administration, operation and management of the Trust or the obligations of the parties hereto, nor shall anything herein set forth, or contained in the terms of the Trust Securities Certificates, be construed so as to constitute the Securityholders from time to time as partners or members of an association.

majority in aggregate Liquidation Amount of all Outstanding Preferred Trust Securities; provided, however, that where such consent under the Indenture would require the consent of each holder of Trust Debt Securities affected thereby, no such consent shall be given by the Property Trustee without the prior written consent of the Holder of each Outstanding Preferred Trust Security. The Trustees shall not revoke any action previously authorized or approved by a vote of the Holders of Preferred Trust Securities, except by a subsequent vote of the Holders of Preferred Trust Securities. The Property Trustee shall notify all Holders of the Preferred Trust Securities of any notice received from the Trust Debt Security Trustee as a result of the Trust being the holder of the Trust Debt Securities. In addition to obtaining the consent of the Holders of the Preferred Trust Securities, prior to taking any of the foregoing actions, the Trustees shall, at the expense of the Sponsor, be provided with an Opinion of Counsel, which shall be nationally recognized independent counsel experienced in such matters to the effect that the Trust will not be classified as an association taxable as a corporation or partnership for United States Federal income tax purposes on account of such action and will continue to be classified as a grantor trust for United States Federal income tax purposes.

(c) Subject to Section 10.02(c) hereof, if any proposed amendment to the Trust Agreement provides for, or the Trustees otherwise propose to effect, (i) any action that would adversely affect in any material respect the powers, preferences or special rights of the Preferred Trust Securities, whether by way of amendment to this Trust Agreement or otherwise, or (ii) the dissolution or liquidation of the Trust, other than pursuant to the terms of this Trust Agreement, then the Holders of Outstanding Preferred Trust Securities will be entitled to vote on such amendment or proposal and such amendment or proposal shall not be effective except with the approval of the Holders of a majority in aggregate Liquidation Amount of the Outstanding Preferred Trust Securities.

Any adjourned meeting may be held as adjourned without further notice.

6.03. Meetings of Holders of Preferred Trust Securities. No annual meeting of Securityholders is required to be held. The Delaware Trustee, however, shall call a meeting of Securityholders to vote on any matter upon the written request of the Holders of at least 25% of the aggregate Liquidation Amount of the Outstanding Preferred Trust Securities and the Delaware Trustee or the Property Trustee may, at any time in their discretion, call a meeting of Holders of the Preferred Trust Securities to vote on any matters as to which the Holders of the Preferred Trust Securities are entitled to vote.

Holders of a majority of the aggregate Liquidation Amount of the Outstanding Preferred Trust Securities, present in person or by proxy, shall constitute a quorum at any meeting of Securityholders.

If a quorum is present at a meeting, an affirmative vote of the Holders of a majority of the

aggregate Liquidation Amount of the Outstanding Preferred Trust Securities present, either in person or by proxy, at such meeting shall constitute the action of the Securityholders, unless this Trust Agreement requires a greater number of affirmative votes.

6.04. Voting Rights. A Securityholder shall be entitled to one vote for each Trust Security in respect of any matter as to which such Securityholder is entitled to vote.

6.05. Proxies, etc. At any meeting of Securityholders, any Securityholder entitled to vote thereat may vote by proxy, provided that no proxy shall be voted at any meeting unless it shall have been placed on file with the Delaware Trustee, or with such other officer or agent of the Trust as the Delaware Trustee may direct, for verification prior to the time at which such vote shall be taken. Pursuant to a resolution of the Property Trustee, proxies may be solicited in the name of the Property Trustee or one or more officers of the Property Trustee. Only Securityholders of record shall be entitled to vote. When Trust Securities are held jointly by several Persons, any one of them may vote at any meeting in person or by proxy in respect of such Trust Securities, but if more than one of them shall be present at such meeting in person or by proxy, and such joint owners or their proxies so present disagree as to any vote to be cast, such vote shall not be received in respect of such Trust Securities. A proxy purporting to be executed by or on behalf of a Securityholder shall be deemed valid unless challenged at or prior to its exercise, and the burden of proving invalidity shall rest on the challenger. No proxy shall be valid more than three years after its date of execution.

6.06. Securityholder Action by Written Consent. Any action which may be taken by Securityholders at a meeting may be taken without a meeting if Holders of the proportion of the Outstanding Preferred Trust Securities required to approve such action shall consent to the action in writing.

6.07. Record Date for Voting and Other Purposes. For the purposes of determining the Securityholders who are entitled to notice of and to vote at any meeting or by written consent, or for the purpose of any other action, the Delaware Trustee may from time to time fix a date, not more than 90 days prior to the date of any meeting of Securityholders, as a record date for the determination of the identity of the Securityholders for such purposes.

6.08. Acts of Securityholders. Any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Trust Agreement to be given, made or taken by Securityholders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Securityholders in person or by an agent duly appointed in writing; and, except as otherwise expressly provided herein, such action shall become effective when such instrument or instruments are delivered to the Delaware Trustee. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Securityholders 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 Trust Agreement and (subject to Section 7.02) conclusive, if made in the manner provided in this Section.

The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or

other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him/her the execution thereof. Where such execution is by a signer acting in a capacity other than his/her individual capacity, such certificate or affidavit shall also constitute sufficient proof of his/her authority. The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner which any Trustee receiving the same deems sufficient.

The ownership of Preferred Trust Securities shall be proved by the Securities Register.

Any request, demand, authorization, direction, notice, consent, waiver or other act of the Securityholder of any Trust Security shall bind every future Securityholder of the same Trust Security and the Securityholder of every Trust Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustees or the Trust in reliance thereon, whether or not notation of such action is made upon such Trust Security.

Without limiting the foregoing, a Securityholder entitled hereunder to take any action hereunder with regard to any particular Trust Security may do so with regard to all or any part of the Liquidation Amount of such Trust Security or by one or more duly appointed agents, each of which may do so pursuant to such appointment with regard to all or any part of such Liquidation Amount.

If any dispute shall arise between the Securityholders and the Delaware Trustee or among such Securityholders or Trustees with respect to the authenticity, validity or binding nature of any request, demand, authorization, direction, consent, waiver or other Act of such Securityholder or Trustee under this Article VI, then the determination of such matter by the Property Trustee shall be conclusive with respect to such matter.

6.09. Inspection of Records. Upon reasonable prior written notice to the Delaware Trustee and the Property Trustee, the records of the Trust shall be open to inspection by Securityholders during normal business hours for any purpose reasonably related to such Securityholder’s interest as a Securityholder.

ARTICLE VII

THE TRUSTEES

7.01. Certain Duties and Responsibilities.

(a) The duties and responsibilities of the Trustees shall be as provided by this Trust Agreement and, in the case of the Property Trustee, also by the Trust Indenture Act. The Property Trustee, other than during the occurrence and continuance of an Event of Default, undertakes to perform only such duties as are specifically set forth in this Trust Agreement and, upon an Event of Default, must exercise the same degree of care and skill as a prudent person would exercise or use in the conduct of his/her own affairs. The Trustees shall have all the privileges, rights and immunities provided by the Delaware Statutory Trust Act. Notwithstanding the foregoing, no provision of this Trust Agreement shall require the Trustees to expend or risk their own funds or otherwise incur any financial liability in the performance of

any of their duties hereunder, or in the exercise of any of their rights or powers, if they 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. Whether or not therein expressly so provided, every provision of this Trust Agreement relating to the conduct or affecting the liability of or affording protection to the Trustees shall be subject to the provisions of this Section. Nothing in this Trust Agreement shall be construed to release the Property Trustee from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct. To the extent that, at law or in equity, the Delaware Trustee has duties (including fiduciary duties) and liabilities relating thereto to the Trust or to the Securityholders, the Delaware Trustee shall not be liable to the Trust or to any Securityholder for the Delaware Trustee’s good faith reliance on the provisions of this Trust Agreement. The provisions of this Trust Agreement, to the extent that they restrict the duties and liabilities of the Delaware Trustee otherwise existing at law or in equity, are agreed by the Sponsor and the Securityholders to replace such other duties and liabilities of the Delaware Trustee.

(b) All payments made by the Property Trustee or any other Paying Agent in respect of the Trust Securities shall be made only from the income and proceeds from the Trust Property. Each Securityholder, by its acceptance of a Trust Security, agrees that (i) it will look solely to the income and proceeds from the Trust Property to the extent available for distribution to it as herein provided and (ii) the Trustees are not personally liable to it for any amount distributable in respect of any Trust Security or for any other liability in respect of any Trust Security. This Section 7.01(b) does not limit the liability of the Trustees expressly set forth elsewhere in this Trust Agreement or, in the case of the Property Trustee, in the Trust Indenture Act.

7.02. Notice of Defaults; Direct Action by Securityholders. Within 90 days after the occurrence of any Event of Default actually known to a Responsible Officer of the Property Trustee, the Property Trustee shall transmit, in the manner and to the extent provided in Section 10.08, notice of such Event of Default to the Securityholders, the Delaware Trustee and the Sponsor, unless such Event of Default shall have been cured or waived. If the Property Trustee has failed to enforce its rights under this Trust Agreement or the Indenture to the fullest extent permitted by law and subject to the terms of this Trust Agreement and the Indenture, any Securityholder may institute a legal proceeding directly to enforce the Property Trustee’s rights under this Trust Agreement or the Indenture with respect to Trust Debt Securities having an aggregate principal amount equal to the aggregate Liquidation Amount of the Preferred Trust Securities of such Securityholder without first instituting a legal proceeding against the Property Trustee or any other Person. To the extent that any action under the Indenture is entitled to be taken by the holders of at least a specified percentage of the principal amount of the outstanding Trust Debt Securities, Holders of at least the same percentage of the Liquidation Amount of the Outstanding Preferred Trust Securities may also take such action in the name of the Trust if such action has not been taken by the Property Trustee. To the fullest extent permitted by law, the foregoing shall be in addition to and not in limitation of any direct rights provided to the Holders of the Preferred Trust Securities against the Trust Debt Security Issuer under the terms of the Indenture, including the right, without any notice or other demand on the Property Trustee, to institute suit for the enforcement of any payment of the principal of and any premium and interest on Trust Debt Securities as provided in Section 6.07 of the Indenture.

7.03. Certain Rights of Property Trustee. Subject to the provisions of Section 7.01:

(a) the Property Trustee may conclusively rely and shall be protected in acting or refraining from acting in good faith upon any resolution, Opinion of Counsel, certificate, written representation of a Holder or transferee, certificate of auditors or any other certificate, statement, instrument, opinion, report, notice, request, consent, order, appraisal, bond, Trust Debt Security, note, other evidence of indebtedness 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) if, other than during the occurrence and continuance of an Event of Default, (i) in performing its duties under this Trust Agreement, the Property Trustee is required to decide between alternative courses of action, or (ii) in construing any of the provisions in this Trust Agreement, the Property Trustee finds the same ambiguous or inconsistent with any other provisions contained herein, or (iii) the Property Trustee is unsure of the application of any provision of this Trust Agreement, then, except as to any matter as to which the Holders of the Preferred Trust Securities are entitled to vote under the terms of this Trust Agreement, the Property Trustee shall deliver a notice to the Sponsor requesting written instructions of the Sponsor as to the course of action to be taken. The Property Trustee shall take such action, or refrain from taking such action, as the Property Trustee shall be instructed in writing to take, or to refrain from taking, by the Sponsor; provided, however, that if the Property Trustee does not receive such instructions of the Sponsor within ten Business Days after it has delivered such notice, or such reasonably shorter period of time set forth in such notice (which to the extent practicable shall not be less than two Business Days), it may, but shall be under no duty to, take or refrain from taking such action not inconsistent with this Trust Agreement as it shall deem advisable and in the best interests of the Securityholders, in which event the Property Trustee shall have no liability except for its own negligent action, its own negligent failure to act or its own willful misconduct;

(c) the Property Trustee may consult with counsel or other experts of its selection and the advice or opinion of such counsel or other experts with respect to legal matters or advice within the scope of such experts’ area of expertise shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon;

(d) the Property Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Trust Agreement at the request or direction of any of the Securityholders pursuant to this Trust Agreement, unless such Securityholders shall have offered to the Property Trustee security or indemnity reasonably satisfactory to the Property Trustee against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction;

(e) the Property Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, approval, bond, debenture, note or other evidence of indebtedness or other paper or document, but the Property Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit at the expense of

the Sponsor and, to the extent permitted by law, shall incur no liability of any kind by reason of such inquiry or investigation;

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

(g) whenever in the administration of this Trust Agreement, the Property Trustee shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Property Trustee (unless other evidence be herein specifically prescribed) may, in the absence of bad faith on its part, conclusively rely upon an Officers’ Certificate;

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

(i) the Property Trustee shall not be deemed to have notice of any Default or an Event of Default unless a Responsible Officer of the Property Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a default is received by the Property Trustee at the Corporate Trust Office and such notice references the Trust Securities and this Trust Agreement;

(j) the rights, privileges, protections, immunities and benefits given to the Property Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Property Trustee in each of its capacities hereunder, and each agent, custodian and other Person employed to act hereunder; and

(k) the Property Trustee may request that the Sponsor deliver an Officers’ Certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Trust Agreement, which Officers’ Certificate may be signed by any person authorized to sign an Officers’ Certificate, including any person specified as so authorized in any such certificate previously delivered and not superseded.

7.04. Not Responsible for Recitals or Issuance of Securities. The recitals contained herein and in the Trust Securities Certificates shall be taken as the statements of the Trust, and the Trustees do not assume any responsibility for their correctness. The Trustees shall not be accountable for the use or application by the Sponsor of the proceeds of the Trust Debt Securities.

The Property Trustee makes no representations as to the value or condition of the property of the Trust or any part thereof. The Property Trustee makes no representations as to the validity or sufficiency of this Trust Agreement or the Trust Securities.

7.05. May Hold Securities. Any Trustee or any other agent of any Trustee or the Trust, in its individual or any other capacity, may become the owner or pledgee of Trust Securities and, subject to Sections 7.08 and 7.13 and except as provided in the definition of the

term Outstanding in Article I, may otherwise deal with the Trust with the same rights it would have if it were not a Trustee or such other agent.

7.06. Compensation; Indemnity; Fees. The Sponsor agrees:

(a) to pay to the Trustees from time to time such compensation as shall have been agreed in writing with the Sponsor for all services rendered by them hereunder (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust);

(b) except as otherwise expressly provided herein, to reimburse the Trustees upon request for all reasonable expenses, disbursements and advances incurred or made by the Trustees in accordance with any provision of this Trust Agreement (including the reasonable compensation and the expenses and disbursements of its agents and counsel), except any such expense, disbursement or advance as shall have been caused by its own negligence or its own wilful misconduct (or, in the case of the Delaware Trustee, any such expense, disbursement or advance as shall have been caused by his/her own gross negligence); and

(c) to indemnify each of the Trustees or any predecessor Trustee for, and to hold the Trustees harmless against, any and all loss, damage, claims, liability, penalty or expense including taxes (other than taxes based on the income of such Trustee) incurred without its own negligence or its wilful misconduct (or, in the case of the Delaware Trustee, incurred without gross negligence or willful misconduct), arising out of or in connection with the acceptance or administration of this Trust Agreement, including the costs and expenses of defending itself against any claim (whether by the Sponsor, any Holder or any other person) or liability in connection with the exercise or performance of any of its powers or duties hereunder.

No Trustee may claim any Lien or charge on any Trust Property as a result of any amount due pursuant to this Section 7.06.

The provisions of this Section 7.06 shall survive the termination of this Trust Agreement and the resignation or removal of the Trustees.

7.07. Corporate Property Trustee Required; Eligibility of Trustees.

(a) There shall at all times be a Property Trustee hereunder. The Property Trustee shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such and has a combined capital and surplus of at least $50,000,000. If any such Person publishes reports of condition at least annually, pursuant to law or to the requirements of its supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Person 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 the Property Trustee with respect to the Trust Securities 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.

(b) There shall at all times be a Delaware Trustee. The Delaware Trustee shall either be (i) a natural person who is at least 21 years of age and a resident of the State of Delaware or (ii) a legal entity with its principal place of business in the State of Delaware and

that otherwise meets the requirements of applicable Delaware law that shall act through one or more persons authorized to bind such entity.

7.08. Conflicting Interests. If the Property Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Property Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Trust Agreement.

7.09. Co-Trustees and Separate Trustee. Unless an Event of Default shall have occurred and be continuing, at any time or times, for the purpose of meeting the legal requirements of the Trust Indenture Act or of any jurisdiction in which any part of the Trust Property may at the time be located, the Sponsor and the Delaware Trustee (and if more than one Delaware Trustee, by agreed action of the majority of such Trustees) shall have power (i) to appoint, and upon the written request of the Delaware Trustee the Sponsor shall for such purpose join with the Delaware Trustee in the execution, delivery, and performance of all instruments and agreements necessary or proper to appoint one or more Persons approved by the Property Trustee either to act as co-trustee, jointly with the Property Trustee, of all or any part of such Trust Property, or to the extent required by law to act as separate trustee of any such property, in either case with such powers as may be provided in the instrument of appointment, and (ii) to vest in such Person or Persons in the capacity aforesaid, any property, title, right or power deemed necessary or desirable, subject to the other provisions of this Section. If the Sponsor does not join in such appointment within 15 days after the receipt by it of a request so to do, or in case an Event of Default has occurred and is continuing, the Property Trustee alone shall have power to make such appointment. Any co-trustee or separate trustee appointed pursuant to this Section shall either be (i) a natural person who is at least 21 years of age and a resident of the United States or (ii) a legal entity with its principal place of business in the United States that shall act through one or more persons authorized to bind such entity.

Should any written instrument from the Sponsor be required by any co-trustee or separate trustee so appointed for more fully confirming to such co-trustee or separate trustee such property, title, right, or power, any and all such instruments shall, on request, be executed, acknowledged, and delivered by the Sponsor.

Every co-trustee or separate trustee shall, to the extent permitted by law, but to such extent only, be appointed subject to the following terms, namely:

(a) The Trust Securities shall be executed and delivered and all rights, powers, duties, and obligations hereunder in respect of the custody of securities, cash and other personal property held by, or required to be deposited or pledged with, the Trustees specified hereunder, shall be exercised, solely by such Trustees and not by such co-trustee or separate trustee.

(b) The rights, powers, duties, and obligations hereby conferred or imposed upon the Property Trustee in respect of any property covered by such appointment shall be conferred or imposed upon and exercised or performed by the Property Trustee or by the Property Trustee and such co-trustee or separate trustee jointly, as shall be provided in the instrument appointing such co-trustee or separate trustee, except to the extent that under any law of any jurisdiction in which any particular act is to be performed, the Property Trustee shall be incompetent or

unqualified to perform such act, in which event such rights, powers, duties and obligations shall be exercised and performed by such co-trustee or separate trustee.

(c) The Property Trustee at any time, by an instrument in writing executed by it, with the written concurrence of the Sponsor, may accept the resignation of or remove any co-trustee or separate trustee appointed under this Section, and, in case an Event of Default under the Indenture has occurred and is continuing, the Property Trustee shall have power to accept the resignation of, or remove, any such co-trustee or separate trustee without the concurrence of the Sponsor. Upon the written request of the Property Trustee, the Sponsor shall join with the Property Trustee in the execution, delivery, and performance of all instruments and agreements necessary or proper to effectuate such resignation or removal. A successor to any co-trustee or separate trustee so resigned or removed may be appointed in the manner provided in this Section.

(d) No co-trustee or separate trustee hereunder shall be personally liable by reason of any act or omission of the Property Trustee, or any other trustee hereunder.

(e) The Property Trustee shall not be liable by reason of any act of a co-trustee or separate trustee.

(f) Any Act of Holders delivered to the Property Trustee shall be deemed to have been delivered to each such co-trustee and separate trustee.

7.10. Resignation and Removal; Appointment of Successor. No resignation or removal of any Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective until the acceptance of appointment by the successor Trustee in accordance with the applicable requirements of Section 7.11.

Subject to the immediately preceding paragraph, any Trustee may resign at any time with respect to the Trust Securities by giving written notice thereof to the Securityholders.

Unless an Event of Default shall have occurred and be continuing, any Trustee may be removed at any time by Act of the Holder of the Common Trust Securities. If an Event of Default shall have occurred and be continuing, the Property Trustee may be removed at such time only by Act of the Holders of a majority in Liquidation Amount of the Outstanding Preferred Trust Securities, delivered to such Trustee (in its individual capacity and on behalf of the Trust); the Delaware Trustee may be removed at any time by the Holder of Common Trust Securities only.

If the instrument of acceptance by the successor Trustee required by Section 7.11 shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation or removal, the Trustee may petition, at the expense of the Sponsor, any court of competent jurisdiction for the appointment of a successor Trustee.

If any Trustee shall resign, be removed or become incapable of acting as Trustee, or if a vacancy shall occur in the office of any Trustee for any cause, at a time when no Event of Default shall have occurred and be continuing, the Holder of Common Trust Securities, by Act of the Holder of Common Trust Securities delivered to the retiring Trustee, shall promptly appoint a successor Trustee or Trustees and the Trust, and the retiring Trustee shall comply with

the applicable requirements of Section 7.11. If the Property Trustee shall resign, be removed or become incapable of continuing to act as the Property Trustee at a time when an Event of Default has occurred and is continuing, the Holders of Preferred Trust Securities, by Act of the Securityholders of a majority in Liquidation Amount of the Outstanding Preferred Trust Securities delivered to the retiring Trustee, shall promptly appoint a successor Trustee or Trustees, and such successor Trustee shall comply with the applicable requirements of Section 7.11. If any Delaware Trustee shall resign, be removed or become incapable of acting as Delaware Trustee at a time when no Event of Default shall have occurred and be continuing, the Holder of Common Trust Securities shall appoint a successor Delaware Trustee. If no successor Trustee shall have been so appointed by the Holder of Common Trust Securities or the Holders of Preferred Trust Securities and accepted appointment in the manner required by Section 7.11, any Securityholder who has been a Securityholder of Trust Securities for at least six months may, on behalf of himself and all others similarly situated, may petition any court of competent jurisdiction for the appointment of a successor Trustee.

The Property Trustee shall give notice of each resignation and each removal of a Trustee and each appointment of a successor Trustee to all Securityholders in the manner provided in Section 10.08 and shall give notice to the Sponsor. Each notice shall include the name of the successor Trustee and the address of its Corporate Trust Office if it is the Property Trustee.

Notwithstanding the foregoing or any other provision of this Trust Agreement, in the event any Delaware Trustee who is a natural person dies or becomes, in the opinion of the Sponsor, incompetent or incapacitated, the vacancy created by such death, incompetence or incapacity may be filled by (a) the unanimous act of the remaining Delaware Trustees if there are at least two of them or (b) otherwise by the Sponsor (with the successor in each case being a Person who satisfies the eligibility requirements for Delaware Trustee, set forth in Section 7.07).

7.11. Acceptance of Appointment by Successor. In case of the appointment hereunder of a successor Trustee, the retiring Trustee and each successor Trustee shall execute and deliver to the Trust and the retiring Trustee an amendment hereto wherein each successor Trustee shall accept such appointment and which (a) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor Trustee all the rights, powers, trusts and duties of the retiring Trustee and (b) shall add to or change any of the provisions of this Trust Agreement as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such amendment shall constitute such Trustees co-trustees of the same trust and that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee and upon the execution and delivery of such amendment the resignation or removal of the retiring Trustee shall become effective to the extent provided therein and each such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee and the Trust; but, on request of the Trust or any successor Trustee, such retiring Trustee shall duly assign, transfer and deliver to such successor Trustee all Trust Property, all proceeds thereof and money held by such retiring Trustee hereunder.

Upon request of any such successor Trustee, the Trust shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all

such rights, powers and trusts referred to in the first or second preceding paragraph, as the case may be.

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

7.12. Merger, Conversion, Consolidation or Succession to Business. Any Person into which any of the Trustees may be merged or converted or with which it may be consolidated, or any Person resulting from any merger, conversion or consolidation to which such Trustee shall be a party, or any Person succeeding to all or substantially all the corporate trust business of such Trustee, shall be the successor of such Trustee hereunder, provided such Person shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto.

7.13. Preferential Collection of Claims Against Sponsor or Trust. If and when the Property Trustee shall be or become a creditor (whether directly or indirectly, secured or unsecured) of the Sponsor or the Trust (or any other obligor upon the Trust Debt Securities or the Trust Securities), including under the terms of Section 7.05 hereof, the Property Trustee shall be subject to and shall take all actions necessary in order to comply with the provisions of the Trust Indenture Act regarding the collection of claims against the Sponsor or Trust (or any such other obligor).

7.14. Reports by Property Trustee. The Property Trustee shall transmit to Holders such reports concerning the Property Trustee and its actions under this Trust Agreement as may be required pursuant to the Trust Indenture Act at the times and in the manner provided pursuant thereto. If required by Section 313(a) of the Trust Indenture Act, the Property Trustee shall, within 60 days after each May 31 following the date of this Trust Agreement deliver to Holders a brief report, dated as of such May 31, which complies with the provisions of such Section 313(a).

A copy of each such report shall, at the time of such transmission to Holders, be filed by the Property Trustee with each stock exchange upon which any Preferred Trust Securities are then listed, with the Commission and with the Trust. The Trust will promptly notify the Property Trustee when any Preferred Trust Securities are listed on any stock exchange.

7.15. Reports to Property Trustee. The Sponsor and the Delaware Trustee on behalf of the Trust shall provide to the Property Trustee such documents, reports and information as required by Section 314 of the Trust Indenture Act (if any) and the compliance certificate required by Section 314(a) of the Trust Indenture Act in the form, in the manner and at the times required by Section 314 of the Trust Indenture Act.

Delivery of such reports, information and documents to the Property Trustee is for informational purposes only and the Property Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Property Trustee is entitled to rely on Officers’ Certificates).

7.16. Evidence of Compliance with Conditions Precedent. The Sponsor and the Delaware Trustee on behalf of the Trust shall provide to the Property Trustee evidence of compliance with the conditions precedent, if any, provided for in this Trust Agreement that relate to any of the matters set forth in Section 314(c) of the Trust Indenture Act.

7.17. Statements Required in Officers’ Certificate.

Each Officers’ Certificate with respect to compliance with a covenant or condition provided for in this Trust Agreement shall include:

(a) a statement that each Person making such Officers’ Certificate or Opinion of Counsel has read such covenant or condition;

(b) a brief statement as to the nature and scope of the examination or investigation upon which the statements or opinions contained in such Officers’ Certificate or Opinion of Counsel are based;

(c) a statement that, in the opinion of each such Person, such Person has made such examination or investigation as is necessary to enable such Person to express an informed opinion as to whether or not such covenant or condition has been complied with; and

(d) a statement that, in the opinion of such Person, such covenant or condition has been complied with; provided, however, that with respect to matters of fact not involving any legal conclusion, an Opinion of Counsel may rely on an Officers’ Certificate or certificates of public officials.

7.18. Number of Trustees.

(a) The number of Trustees shall be two, one of which must be a Delaware Trustee. The Holder of all of the Common Trust Securities by written instrument may increase the number of Delaware Trustees to more than one, and, if so increased, may decrease the number of Delaware Trustees to no less than one. During any period in which the number of Delaware Trustees is more than one, the Delaware Trustees shall act by majority vote.

(b) If a Trustee ceases to hold office for any reason and, with respect to the Delaware Trustee, the number of Delaware Trustees is not reduced as permitted by Section 7.18(a), or if the number of Delaware Trustees is increased pursuant to Section 7.18(a), a vacancy shall occur. The vacancy shall be filled with a Trustee appointed in accordance with Section 7.10.

(c) The death, dissolution, termination, resignation, retirement, removal, bankruptcy, incompetence or incapacity to perform the duties of a Trustee shall not operate to annul, dissolve or terminate the Trust. Whenever a vacancy shall occur, until such vacancy is filled by the appointment of an Delaware Trustee in accordance with Section 7.10, the Delaware Trustees in office, regardless of their number (and notwithstanding any other provision of this Trust Agreement), shall have all the powers granted to the Delaware Trustee and shall discharge all the duties imposed upon the Delaware Trustees by this Trust Agreement.

7.19. Delegation of Power.

(a) Any Delaware Trustee may, by power of attorney consistent with applicable law, delegate to any natural person over the age of 21 his/her power for the purpose of executing any documents contemplated in Section 2.07(a), including any registration statement or amendment thereto filed with the Commission, or making any other governmental filing; and

(b) the Delaware Trustees shall have power to delegate from time to time to such of their number, if there is more than one Delaware Trustee, or to the Sponsor the doing of such things and the execution of such instruments either in the name of the Trust or the names of the Delaware Trustees or otherwise as the Delaware Trustees may deem expedient, to the extent such delegation is not prohibited by applicable law or contrary to the provisions of the Trust, as set forth herein.

7.20. Voting. Except as otherwise provided in this Trust Agreement, the consent or vote of the Trustees shall be approved by the Delaware Trustee or, if more than one, by a majority of the Delaware Trustees.

8.01. Dissolution Upon Expiration Date. Unless earlier dissolved, the Trust shall automatically dissolve on December 31, 2055 (the “Expiration Date”).

8.02. Early Termination. The earliest to occur of any of the following events is an “Early Termination Event”:

(a) the occurrence of a Bankruptcy Event in respect of, or the dissolution or liquidation of, the Sponsor or an acceleration of the maturity of the Trust Debt Securities pursuant to Section 6.02 of the Indenture;

(b) upon the election of the Sponsor to dissolve the Trust and cause the distribution of a Like Amount of Trust Debt Securities to the Holders of the Trust Securities in accordance with their terms;

(d) an order for dissolution of the Trust shall have been entered by a court of competent jurisdiction.

The election of the Sponsor pursuant to Section 8.02(b) shall be made by the Sponsor giving written notice to the Trustees not less than 30 days prior to the date of distribution of the Trust Debt Securities. Such notice shall specify the date of distribution of the Trust Debt Securities and shall be accompanied by an Opinion of Counsel, which shall be nationally recognized independent counsel experienced in such matters, that such event will not be a taxable event to the Holders of the Trust Securities for Federal income tax purposes.

8.03. Termination. The respective obligations and responsibilities of the Trustees and the Trust shall terminate upon the latest to occur of the following: (a) the distribution by the Property Trustee to Securityholders upon the winding up of the Trust pursuant to Section 8.04 of all amounts required to be distributed hereunder upon the final payment of the Trust Securities; (b) the payment of any expenses owed by the Trust; and (c) the discharge of all administrative duties of the Delaware Trustee, including the performance of any tax reporting obligations with respect to the Trust or the Securityholders and the filing of the Certificate of Cancellation with the Secretary of State of the State of Delaware.

8.04. Winding Up.

(a) If an Early Termination Event specified in clause (a) or (d) of Section 8.02 occurs or upon the Expiration Date, the Trust shall be wound up by the Trustees as expeditiously as the Trustees determine to be possible by distributing, after satisfaction of liabilities to creditors of the Trust as provided by applicable law, to each Securityholder a Like Amount of Trust Debt Securities, subject to Section 8.04(d). If an Early Termination Event specified in clause (b) of Section 8.02 occurs, the Trust shall be liquidated by the Trustee on the date of distribution of the Trust Debt Securities specified by the Sponsor in its notice delivered pursuant to Section 8.02. Notice of liquidation shall be given by the Property Trustee by first-class mail, postage prepaid, mailed not later than 30 nor more than 60 days prior to the Liquidation Date to each Holder of Trust Securities at such Holder’s address appearing in the Securities Register. All notices of liquidation shall:

(i) state the Liquidation Date;

(ii) state that from and after the Liquidation Date, the Trust Securities will no longer be deemed to be Outstanding and any Trust Securities Certificates not surrendered for exchange will be deemed to represent a Like Amount of Trust Debt Securities; and

(iii) provide such information with respect to the mechanics by which Holders may exchange Trust Securities Certificates for certificates evidencing Trust Debt Securities, or, if Section 8.04(d) applies, receive a Liquidation Distribution, as the Delaware Trustee or the Property Trustee shall deem appropriate.

(b) In order to effect the winding up of the Trust and distribution of the Trust Debt Securities to Securityholders, the Property Trustee, either itself acting as exchange agent or through the appointment of a separate exchange agent, shall establish such procedures as it shall deem appropriate to effect the distribution of Trust Debt Securities in exchange for the Outstanding Trust Securities Certificates.

(c) Except where Section 8.02(c) applies, on or after the Liquidation Date, (i) the Trust Securities will no longer be deemed to be Outstanding, (ii) certificates representing a Like Amount of Trust Debt Securities will be issued to Holders of Trust Securities Certificates, upon surrender of such certificates to the Delaware Trustee or its agent for exchange, (iii) the Sponsor shall use its best efforts to have the Trust Debt Securities listed on the New York Stock

Exchange or such other exchange as the Preferred Trust Securities are then listed and shall take any reasonable action necessary to effect the distribution of the Trust Debt Securities, (iv) any Trust Securities Certificates not so surrendered for exchange will be deemed to represent a Like Amount of Trust Debt Securities, accruing interest at the rate then borne by the Trust Debt Securities from the last Distribution Date on which a Distribution was made on such Trust Certificates until such certificates are so surrendered (and until such certificates are so surrendered, no payments of interest or principal will be made to Holders of Trust Securities Certificates with respect to such Trust Debt Securities) and (v) all rights of Securityholders holding Trust Securities will cease, except the right of such Securityholders to receive Trust Debt Securities upon surrender of Trust Securities Certificates.

(d) In the event that, notwithstanding the other provisions of this Section 8.04, whether because of an order for dissolution entered by a court of competent jurisdiction or otherwise, distribution of the Trust Debt Securities in the manner provided herein is determined by the Property Trustee not to be practical, the Trust Property shall be liquidated, and the Trust shall be terminated, by the Property Trustee in such manner as the Property Trustee determines. In such event, Securityholders will be entitled to receive out of the assets of the Trust available for distribution to Securityholders, after satisfaction of liabilities to creditors of the Trust as provided by applicable law, an amount equal to the Liquidation Amount per Trust Security plus accumulated and unpaid Distributions thereon to the date of payment (such amount being the “Liquidation Distribution”). If, upon any such dissolution, the Liquidation Distribution can be paid only in part because the Trust has insufficient assets available to pay in full the aggregate Liquidation Distribution, then, subject to the next succeeding sentence, the amounts payable by the Trust on the Trust Securities shall be paid on a pro rata basis (based upon Liquidation Amounts). The Holder of the Common Trust Securities will be entitled to receive Liquidation Distributions upon any such dissolution pro rata (determined as aforesaid) with Holders of Preferred Trust Securities, except that, if an Event of Default has occurred and is continuing, the Preferred Trust Securities shall have a priority over the Common Trust Securities, and no Liquidation Distribution will be paid to the Holders of the Common Trust Securities unless and until receipt by all Holders of the Preferred Trust Securities of the entire Liquidation Distribution payable in respect thereof.

ARTICLE IX

MERGERS, ETC.

9.01. Mergers, Consolidations, Amalgamations or Replacements of the Trust. The Trust may not merge with or into, consolidate, amalgamate, or be replaced by, or convey, transfer or lease its properties and assets as an entirety or substantially as an entirety to any corporation or other entity, except as described below. The Trust may, at the request of the Sponsor, with the consent of the Delaware Trustee and without the consent of the Holders of the Trust Securities, merge with or into, consolidate, amalgamate, or be replaced by, a trust organized as such under the laws of any State; provided, that (i) such successor entity either (a) expressly assumes all of the obligations of the Trust with respect to the Trust Securities or (b) substitutes for the Trust Securities other securities having substantially the same terms as the Trust Securities (the “Successor Securities”) so long as the Successor Securities rank the same as the Trust Securities rank with respect to the payment of Distributions and payments upon liquidation, redemption and otherwise, (ii) the Sponsor expressly appoints a trustee of such

successor entity possessing the same powers and duties as the Property Trustee as the holder of the Trust Debt Securities, (iii) such of the Successor Securities that correspond to the Preferred Trust Securities (the “Preferred Successor Securities”) are listed, or any Preferred Successor Securities will be listed upon notification of issuance, on any national securities exchange or other organization on which the Trust Securities are then listed or quoted, (iv) such merger, consolidation, amalgamation, replacement, conveyance, transfer or lease does not cause the Preferred Trust Securities (including any Preferred Successor Securities) to be downgraded, placed under surveillance or review or withdrawn by any nationally recognized statistical rating organization, (v) such merger, consolidation, amalgamation, replacement, conveyance, transfer or lease does not adversely affect the rights, preferences and privileges of the Holders of the Trust Securities (including any Successor Securities) in any material respect, (vi) such successor entity has a purpose substantially similar to that of the Trust, (vii) prior to such merger, consolidation, amalgamation, replacement, transfer or lease, the Sponsor and the Property Trustee have received an Opinion of Counsel, which shall be nationally recognized independent counsel experienced in such matters, to the effect that (a) such merger, consolidation, amalgamation, replacement, conveyance, transfer or lease does not adversely affect the rights, preferences and privileges of the Holders of the Trust Securities (including any Successor Securities) in any material respect, and (b) following such merger, consolidation, amalgamation, replacement, conveyance, transfer or lease, neither the Trust nor such successor entity will be required to register as an investment company under the 1940 Act and the Trust (or the successor entity) will continue to be classified as a grantor trust for United States federal income tax purposes and (viii) the Sponsor or any permitted successor assignee owns all of the common trust securities of such successor entity and guarantees the obligations of such successor entity under the Successor Securities at least to the extent provided by the Guarantee and this Trust Agreement. Notwithstanding the foregoing, the Trust shall not, except with the consent of all Holders of the Trust Securities, merge with or into, consolidate, amalgamate, or be replaced by or convey, transfer or lease its properties and assets substantially as an entirety to, any other entity or permit any other entity to consolidate, amalgamate, merge with or into, or replace it if such consolidation, conversion, amalgamation, merger, replacement, conveyance, transfer or lease would cause the Trust or the successor entity not to be classified as a grantor trust for United States Federal income tax purposes or would cause each Holder of Trust Securities not to be treated as owning an undivided beneficial ownership interest in the Trust Debt Securities.

ARTICLE X

MISCELLANEOUS PROVISIONS
