The Company shall have the right, by one or more written instruments executed and delivered to the Collateral Agent, to direct the time, method and place of conducting any proceeding for the realization of any right or remedy available to the Collateral Agent, or of exercising any power conferred on the Collateral Agent, or to direct the taking or refraining from taking of any action authorized by this Agreement; provided, however, that (i) such direction shall not conflict with the provisions of any law or of this Agreement or involve the Collateral Agent in personal liability and (ii) the Collateral Agent shall be indemnified to its satisfaction as provided herein. Nothing contained in this Section 9.02 shall impair the right of the Collateral Agent in its discretion to take any action or omit to take any action which it deems proper and which is not inconsistent with such direction. None of the Collateral Agent, the Custodial Agent or the Securities Intermediary has any obligation or responsibility to file UCC financing statements.

Section 9.03 Reliance by Collateral Agent, Custodial Agent and Securities Intermediary. Each of the Collateral Agent, the Custodial Agent and the Securities Intermediary shall be entitled, in the absence of bad faith, to rely conclusively upon any certification, order, judgment, opinion, notice or other written communication (including, without limitation, any thereof by e-mail or similar electronic means, telecopy, telex or facsimile) believed by it to be genuine and correct and to have been signed or sent by or on behalf of the proper Person or Persons (without being required to determine the correctness of any fact stated therein) and consult with and conclusively rely upon advice, opinions and statements of legal counsel and other experts selected by the Collateral Agent, the Custodial Agent or the Securities Intermediary, as the case may be. As to any matters not expressly provided for by this Agreement, the Collateral Agent, the Custodial Agent and the Securities Intermediary shall in all cases be fully protected in acting, or in refraining from acting, hereunder in accordance with instructions given by the Company in accordance with this Agreement.

(a) Whenever in the administration of the provisions of this Agreement the Collateral Agent, the Custodial Agent or the Securities Intermediary shall deem it necessary or desirable that a matter be proved or established prior to taking or suffering any action to be taken hereunder, such matter (unless other evidence in respect thereof be herein specifically prescribed) may, in the absence of gross negligence or bad faith on the part of the Collateral Agent, the Custodial Agent or the Securities Intermediary, be deemed to be conclusively proved and established by a certificate signed by one of the Company’s officers, and delivered to the Collateral Agent, the Custodial Agent or the Securities Intermediary and such certificate, in the absence of gross negligence or bad faith on the part of the Collateral Agent, the Custodial Agent or the Securities Intermediary, shall be full warrant to the Collateral Agent, the Custodial Agent or the Securities Intermediary for any action taken, suffered or omitted by it under the provisions of this Agreement upon the faith thereof.

(b) The Collateral Agent, the Custodial Agent or the Securities Intermediary 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, entitlement order, approval or other paper or document.

Section 9.05 Merger, Conversion, Consolidation or Succession to Business. Any corporation into which the Collateral Agent, the Custodial Agent or the Securities Intermediary 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, the Custodial Agent or the Securities Intermediary shall be a party, or any corporation succeeding to all or substantially all of the corporate trust business of the Collateral Agent, the Custodial Agent or the Securities Intermediary shall be the successor of the Collateral Agent, the Custodial Agent or the Securities Intermediary hereunder without the execution or filing of any paper with any party hereto or any further act on the part of any of the parties hereto except where an instrument of transfer or assignment is required by law to effect such succession, anything herein to the contrary notwithstanding.

Section 9.06 Rights in Other Capacities. The Collateral Agent, the Custodial Agent and the Securities Intermediary and their affiliates may (without having to account therefor to the Company) accept deposits from, lend money to, make their investments in and generally engage in any kind of banking, trust or other business with the Purchase Contract Agent, any other Person interested herein and any Holder of Units (and any of their respective subsidiaries or affiliates) as if it were not acting as the Collateral Agent, the Custodial Agent or the Securities Intermediary, as the case may be, and the Collateral Agent, the Custodial Agent, the Securities Intermediary and their affiliates may accept fees and other consideration from the Purchase Contract Agent and any Holder of Units without having to account for the same to the Company; provided that each of the Securities Intermediary, the Custodial Agent and the Collateral Agent covenants and agrees with the Company that it shall not accept, receive or permit there to be created in favor of itself and shall take no affirmative action to permit there to be created in favor of any other Person, any security interest, lien or other encumbrance of any kind in or upon the Collateral other than the lien created by the Pledge.

Section 9.07 Non-reliance on Collateral Agent, the Custodial Agent and Securities Intermediary. None of the Securities Intermediary, the Custodial Agent or the Collateral Agent shall be required to keep itself informed as to the performance or observance by the Purchase Contract Agent or any Holder of Units of this Agreement, the Purchase Contract Agreement, the Units or any other document referred to or provided for herein or therein or to inspect the properties or books of the Purchase Contract Agent or any Holder of Units. None of the Collateral Agent, the Custodial Agent or the Securities Intermediary shall have any duty or responsibility to provide the Company with any credit or other information concerning the affairs, financial condition or business of the Purchase Contract Agent or any Holder of Units (or any of their respective affiliates) that may come into the possession of the Collateral Agent, the Custodial Agent or the Securities Intermediary or any of their respective affiliates.

Section 9.08 Compensation and Indemnity. The Company agrees to:

(a) pay the Collateral Agent, the Custodial Agent and the Securities Intermediary from time to time such compensation as shall be agreed in writing between the Company and the Collateral Agent, the Custodial Agent or the Securities Intermediary, as the case may be, for all services rendered by them hereunder;

(b) indemnify and hold harmless the Collateral Agent, the Custodial Agent, the Securities Intermediary and each of their respective directors, officers, agents and employees (collectively, the “Indemnitees”), from and against any and all claims, liabilities, losses, damages, fines, penalties and expenses (including reasonable fees and expenses of counsel) and taxes (other than those based upon, determined by or measured by the income of the Collateral Agent, the Custodial Agent and Securities Intermediary) (collectively, “Losses” and individually, a “Loss”) that may be imposed on, incurred by, or asserted against, the Indemnitees or any of them for following any instructions or other directions upon which either the Collateral Agent, the Custodial Agent or the Securities Intermediary is entitled to rely pursuant to the terms of this Agreement, provided that the Collateral Agent, the Custodial Agent or the Securities Intermediary has not acted with gross negligence or engaged in willful misconduct or bad faith with respect to the specific Loss against which indemnification is sought; and

(c) in addition to and not in limitation of paragraph (b) immediately above, indemnify and hold the Indemnitees and each of them harmless from and against any and all Losses that may be imposed on, incurred by or asserted against, the Indemnitees or any of them in connection with or arising out of the Collateral Agent’s, the Custodial Agent’s or the Securities Intermediary’s acceptance or performance of its powers and duties under this Agreement, provided that the Collateral Agent, the Custodial Agent or the Securities Intermediary has not acted with gross negligence or engaged in willful misconduct or bad faith with respect to the specific Loss against which indemnification is sought.

The provisions of this Section 9.08 and Section 11.07 shall survive the resignation or removal of the Collateral Agent, Custodial Agent or Securities Intermediary and the termination of this Agreement.

Section 9.09 Failure to Act. In the event of any ambiguity in the provisions of this Agreement or any dispute between or conflicting claims by or among the parties hereto or any other Person with respect to any funds or property deposited hereunder, then at its sole option, each of the Collateral Agent, the Custodial Agent and the Securities Intermediary shall be entitled, after prompt notice to the Company and the Purchase Contract Agent, to

refuse to comply with any and all claims, demands or instructions with respect to such property or funds so long as such dispute or conflict shall continue, and the Collateral Agent, the Custodial Agent and the Securities Intermediary shall not be or become liable in any way to any of the parties hereto for its failure or refusal to comply with such conflicting claims, demands or instructions. The Collateral Agent, the Custodial Agent and the Securities Intermediary shall be entitled to refuse to act until either:

(a) such conflicting or adverse claims or demands shall have been finally determined by a court of competent jurisdiction or settled by agreement between the conflicting parties as evidenced in a writing satisfactory to the Collateral Agent, the Custodial Agent or the Securities Intermediary; or

(b) the Collateral Agent, the Custodial Agent or the Securities Intermediary shall have received security or an indemnity satisfactory to it sufficient to save it harmless from and against any and all loss, liability or reasonable out-of-pocket expense which it may incur by reason of its acting.

The Collateral Agent, the Custodial Agent and the Securities Intermediary may in addition elect to commence an interpleader action or seek other judicial relief or orders as the Collateral Agent, the Custodial Agent or the Securities Intermediary may deem necessary. Notwithstanding anything contained herein to the contrary, none of the Collateral Agent, the Custodial Agent or the Securities Intermediary shall be required to take any action that is in its opinion contrary to law or to the terms of this Agreement, or which would in its opinion subject it or any of its officers, employees or directors to liability.

Section 9.10 Resignation of Collateral Agent, the Custodial Agent and Securities Intermediary.

(a) Subject to the appointment and acceptance of a successor Collateral Agent, Custodial Agent or Securities Intermediary as provided below:

(i) the Collateral Agent, the Custodial Agent and the Securities Intermediary may resign at any time by giving notice thereof to the Company and the Purchase Contract Agent as attorney-in-fact for the Holders of Units;

(ii) the Collateral Agent, the Custodial Agent and the Securities Intermediary may be removed at any time by the Company; and

(ii) if the Collateral Agent, the Custodial Agent or the Securities Intermediary fails to perform any of its material obligations hereunder in any material respect for a period of not less than 20 days after receiving written notice of such failure by the Purchase Contract Agent and such failure shall be continuing, the Collateral Agent, the Custodial Agent and the Securities Intermediary may be removed by the Purchase Contract Agent, acting at the direction of the Holders of Units.

The Purchase Contract Agent shall promptly notify the Company of any removal of the Collateral Agent, the Custodial Agent or the Securities Intermediary pursuant to clause (iii) of this Section 9.10. Upon any such resignation or removal, the Company shall have the right to appoint a successor Collateral Agent, Custodial Agent or Securities Intermediary, as the case may be, which shall not be an Affiliate of the Purchase Contract Agent. If no successor Collateral Agent, Custodial Agent or Securities Intermediary shall have been so appointed and shall have accepted such appointment within 30 days after the retiring Collateral Agent’s, Custodial Agent’s or Securities Intermediary’s giving of notice of resignation or the Company’s or the Purchase Contract Agent’s giving notice of such removal, then the retiring or removed Collateral Agent, Custodial Agent or Securities Intermediary may petition any court of competent jurisdiction, at the expense of the Company, for the appointment of a successor Collateral Agent, Custodial Agent or Securities Intermediary. The Collateral Agent, the Custodial Agent and the Securities Intermediary shall each be a bank or a national banking association which has an office (or an agency office) in New York City with a combined capital and surplus of at least $50,000,000. Upon the acceptance of any appointment as Collateral Agent, Custodial Agent or Securities Intermediary hereunder by a successor Collateral Agent, Custodial Agent or Securities Intermediary, as the case may be, such successor Collateral Agent, Custodial Agent or Securities Intermediary, as the case may be, shall thereupon succeed to and become vested with all the

rights, powers, privileges and duties of the retiring Collateral Agent, Custodial Agent or Securities Intermediary, as the case may be, and the retiring Collateral Agent, Custodial Agent or Securities Intermediary, as the case may be, shall take all appropriate action, subject to payment of any amounts then due and payable to it hereunder, to transfer any money and property held by it hereunder (including the Collateral) to such successor. The retiring Collateral Agent, Custodial Agent or Securities Intermediary shall, upon such succession, be discharged from its duties and obligations as Collateral Agent, Custodial Agent or Securities Intermediary hereunder. After any retiring Collateral Agent’s, Custodial Agent’s or Securities Intermediary’s resignation hereunder as Collateral Agent, Custodial Agent or Securities Intermediary, the provisions of this Article 9 shall continue in effect for its benefit in respect of any actions taken or omitted to be taken by it while it was acting as the Collateral Agent, Custodial Agent or Securities Intermediary. Any resignation or removal of the Collateral Agent, Custodial Agent or Securities Intermediary hereunder, at a time when such Person is acting as the Collateral Agent, Custodial Agent or Securities Intermediary, shall be deemed for all purposes of this Agreement as the simultaneous resignation or removal of the Collateral Agent, Securities Intermediary or Custodial Agent, as the case may be.

(b) Because U.S. Bank National Association is serving as the Collateral Agent hereunder and the Purchase Contract Agent under the Purchase Contract Agreement, if an event of default (other than an event of default occurring as a result of a Failed Final Remarketing) occurs hereunder or under the Purchase Contract Agreement, U.S. Bank National Association will resign as the Collateral Agent, but continue to act as the Purchase Contract Agent. A successor Collateral Agent will be appointed in accordance with the terms hereof. If any such event of default is cured or waived prior to the appointment of a successor Collateral Agent, the duty of U.S. Bank National Association to resign in respect of such event of default shall cease.

Section 9.11 Right to Appoint Agent or Advisor. The Collateral Agent shall have the right to appoint agents or advisors in connection with any of its duties hereunder, and the Collateral Agent shall not be liable for any action taken or omitted by, or in reliance upon the advice of, such agents or advisors selected in good faith. The appointment of agents pursuant to this Section 9.11 shall be subject to prior written consent of the Company, which consent shall not be unreasonably withheld.

Section 9.12 Survival. The provisions of this Article 9 shall survive termination of this Agreement and the resignation or removal of the Collateral Agent, the Custodial Agent or the Securities Intermediary.

Section 9.13 Exculpation. Anything contained in this Agreement to the contrary notwithstanding, in no event shall the Collateral Agent, the Custodial Agent or the Securities Intermediary or their officers, directors, employees or agents be liable under this Agreement to any third party for indirect, special, punitive, or consequential loss or damage of any kind whatsoever, including, but not limited to, lost profits, whether or not the likelihood of such loss or damage was known to the Collateral Agent, the Custodial Agent or the Securities Intermediary, or any of them and regardless of the form of action.

ARTICLE 10

Without the consent of any Holders, the Company, when duly authorized, the Collateral Agent, the Custodial Agent, the Securities Intermediary and the Purchase Contract Agent, at any time and from time to time, may amend this Agreement, in form satisfactory to the Company, the Collateral Agent, the Custodial Agent, the Securities Intermediary and the Purchase Contract Agent, to:

(a) evidence the succession of another Person to the Company and the assumption by any such successor of the covenants of the Company;

(b) evidence and provide for the acceptance of appointment hereunder by a successor Collateral Agent, Custodial Agent, Securities Intermediary or Purchase Contract Agent;

(c) add to the covenants of the Company for the benefit of the Holders, or surrender any right or power herein conferred upon the Company, provided that such covenants or such surrender do not adversely affect the validity, perfection or priority of the Pledge created hereunder;

(d) cure any ambiguity (or formal defect), correct or supplement any provisions herein which may be inconsistent with any other such provisions herein; or

(a) change the amount or type of Collateral underlying a Unit (except for the rights of holders of Corporate Units to substitute the Treasury Securities for the Pledged Senior Notes or the Pledged Applicable Ownership Interests, as the case may be, or the rights of Holders of Treasury Units to substitute Senior Notes or the Applicable Ownership Interests (as specified in clause (i) of the definition of such term) in the Treasury Portfolio, as applicable, for the Pledged Treasury Securities), unless such change is not adverse to the Holders, does not impair the right of the Holder of any Unit to receive distributions on the underlying Collateral or otherwise adversely affect the Holder’s rights in or to such Collateral;

(b) otherwise effect any action that would require the consent of the Holder of each Outstanding Unit affected thereby pursuant to the Purchase Contract Agreement if such action were effected by a modification or amendment of the provisions of the Purchase Contract Agreement; or

(c) reduce the percentage of Purchase Contracts the consent of whose Holders is required for the modification or amendment of the provisions of this Agreement;

provided that if any amendment or proposal referred to above would adversely affect only the Corporate Units or only the Treasury Units, then only the affected class of Holders as of the record date for the Holders entitled to vote thereon will be entitled to vote on such amendment or proposal, and such amendment or proposal shall not be effective except with the consent of Holders of not less than a majority of such class; provided, further, that the unanimous consent of the Holders of each outstanding Purchase Contract of such class affected thereby shall be required to approve any amendment or proposal specified in clauses (a) through (c) above.

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

Section 10.03 Execution of Amendments. In executing any amendment permitted by this Article, the Collateral Agent, the Custodial Agent, the Securities Intermediary and the Purchase Contract Agent shall be entitled to receive and (subject to Section 7.01 of the Purchase Contract Agreement with respect to the Purchase Contract Agent) shall be fully authorized and protected in relying upon, an Opinion of Counsel and an Officers’ Certificate stating that the execution of such amendment is authorized or permitted by this Agreement and that all conditions precedent, if any, to the execution and delivery of such amendment have been satisfied. The Collateral Agent, Custodial Agent, Securities Intermediary and Purchase Contract Agent may, but shall not be obligated to, enter into any such amendment which affects their own respective rights, duties or immunities under this Agreement or otherwise.

Section 10.04 Effect of Amendments. Upon the execution of any amendment under this Article, this Agreement shall be modified in accordance therewith, and such amendment shall form a part of this Agreement for all purposes; and every Holder of Certificates theretofore or thereafter authenticated, executed on behalf of the Holders and delivered under the Purchase Contract Agreement shall be bound thereby.

Section 10.05 Reference of Amendments. Certificates authenticated, executed on behalf of the Holders and delivered after the execution of any amendment pursuant to this Section may, and shall if required by the Collateral Agent or the Purchase Contract Agent, bear a notation in form approved by the Purchase Contract Agent and the Collateral Agent as to any matter provided for in such amendment. If the Company shall so determine, new Certificates so modified as to conform, in the opinion of the Collateral Agent, the Purchase Contract Agent and the Company, to any such amendment may be prepared and executed by the Company and authenticated, executed on behalf of the Holders and delivered by the Purchase Contract Agent in accordance with the Purchase Contract Agreement in exchange for Certificates representing Outstanding Units.

No failure on the part of the Company, the Collateral Agent, the Custodial Agent, the Securities Intermediary or any of their respective agents to exercise, and no course of dealing with respect to, and no delay in exercising, any right, power or remedy hereunder shall operate as a waiver thereof; nor shall any single or partial exercise by the Company, the Collateral Agent, the Custodial Agent, the Securities Intermediary or any of their respective agents of any right, power or remedy hereunder preclude any other or further exercise thereof or the exercise of any other right, power or remedy.
