ARTICLE TWO

THE TREASURY STRIPS

Section 2.01. Delivery of Treasury Strips to the Custodian. On the Closing Date (as defined in the Underwriting Agreement), the initial Holders have acquired from Goldman Sachs & Co. LLC (as a Representative on behalf of itself and the other underwriters named in the Underwriting Agreement) the Treasury Strips described on Schedule 1 hereto and directed them to be delivered to the Custodian by causing the Custodian or its nominee to be the holder of security entitlements for such Treasury Strips on the records of the Federal Reserve Bank of New York for and on behalf of the Holders, and the Custodian has accepted delivery of the Treasury Strips. Each Unit evidences ownership of the related Treasury Strips Component held by the Custodian hereunder as agent for and on behalf of the Holders as identified by a security entitlement credited to an account on the records of the Custodian. For greater certainty, each Holder shall have a separate property interest in each of its Treasury Strips Component and shall have no interest whatsoever in any other Holder’s Treasury Strips Component and Holders shall not be considered to own Treasury Strips Components as joint tenants or tenants in common. The Custodian shall act as agent for the Holders and no provision hereof is intended to create or shall be construed as having created a trust of any kind or any fiduciary duty owed by the Custodian to any Holder.

Section 2.02. Acceptance by Custodian. The Custodian hereby acknowledges that, on the Closing Date (as defined in the Underwriting Agreement), the Custodian has received the Treasury Strips listed in Schedule 1 in accordance with the Purchase Contract Agreement, and in the manner described in, Section 2.01. The Custodian agrees to accept additional free deliveries of Treasury Strips in accordance with the terms of the Purchase Contract Agreement, including, without limitation, pursuant to Section 2.04 of the Purchase Contract Agreement and/or in connection with any exercise by the Underwriters (as defined in the Underwriting Agreement) of their option to purchase additional Purchase Contracts pursuant to Section 2(b) of the Underwriting Agreement. The Custodian shall accept all Treasury Strips delivered (or caused to be delivered) free hereunder as custodian for the Holders and the Custodian shall hold the Treasury Strips in a separate Custody Account as defined in and as provided in Section 2.04 for and on behalf of the Holders. The Custodian shall hold the Treasury Strips delivered to it pursuant to this Agreement solely as custodian and not as a fiduciary, identified separate and apart from the general assets of the Custodian for and on behalf of the Holders. The Custodian shall not have the authority or obligation to assign, transfer, pledge, set off or otherwise dispose of any of the Treasury Strips, or of any interests therein, except as provided hereunder or as required by law.

7

Section 2.03. Payment of Amounts Received Upon Maturity of Treasury Strips. On any Payment Date on which amounts are received by the Custodian on payments of the Treasury Strips (or, if such amounts are received between Payment Dates, on the next Payment Date after the Custodian receives such amounts), the Custodian shall forward all such amounts the Custodian receives to the Holders as instructed by the Purchase Contract Agent.

Section 2.04. Establishment of Custody Account. The Custodian, as agent for the Holders, shall establish and maintain a separate account bearing a designation clearly indicating that the funds and assets deposited therein are held in custody for the Holders (the “Custody Account”). The Custody Account shall at all times be maintained as a segregated custodial account identified separate and apart from the general assets of the Custodian and all other accounts, funds and property of or in the possession of the Custodian, including any other custody account. The Treasury Strips and any moneys held in the Custody Account shall not at any time be commingled with any other assets or property held by the Custodian.

Notwithstanding anything else in this Agreement, the Custodian shall not hold cash as a fiduciary. The Custodian shall at all times maintain accurate records reflecting each transaction in the Custody Account in connection with the Units and the related Treasury Strips Components evidenced thereby. The Custodian shall have no power or authority to assign, transfer, pledge, set off or otherwise dispose of any of the Treasury Strips, or any interest therein, except as provided hereunder or as required by law. The Custody Account shall be non-interest bearing and the amounts therein shall not be invested.

Section 2.05. Collection of Payments on Treasury Strips. Not later than the close of business on each Business Day on which the Custodian receives any payments of the Treasury Strips in the form of immediately available funds, the Custodian shall credit to or deposit in the Custody Account the amount of such payment. All moneys so received shall be held by the Custodian in the Custody Account until the Custodian receives the Purchase Contract Agent’s instruction to transfer funds.

Section 2.06. Delivery of Treasury Strips to Holders. (a) Treasury Strips shall be delivered to Holders only and in such denominations as instructed by the Purchase Contract Agent pursuant to Section 4.06 of the Purchase Contract Agreement, pursuant to Section 4.07 of the Purchase Contract Agreement, pursuant to Section 4.08 of the Purchase Contract Agreement or pursuant to Section 2.03 of the Purchase Contract Agreement.

(b) The Custodian is entitled to rely and act upon Instructions of any Authorized Person until the Custodian has received notice of any change from the Purchase Contract Agent and has had a reasonable time to note and implement such change. The Custodian is authorized to rely upon any Instructions received by any means, provided that the Custodian and the Purchase Contract Agent have agreed upon the means of transmission and the method of identification for the Instructions.

8

(c) Absent a contrary Instruction, the Custodian shall carry out the following without further Instructions:

(i) in the Purchase Contract Agent’s name or on its behalf, sign any affidavits, certificates of ownership and other certificates and documents relating to Treasury Strips which may be required by any tax or regulatory authority;

(ii) notify the Purchase Contract Agent of notices, circulars, reports and announcements which the Custodian has received, in the course of acting in the capacity of custodian, concerning Treasury Strips held on the Purchase Contract Agent’s behalf that require discretionary action;

(iii) make any payment by debiting the Custody Account or any other designated account of the Purchase Contract Agent with the Custodian as required to effect any Instruction; and

(f) The Purchase Contract Agent shall give, or shall cause such successor Custodian to give, notice of each resignation and each removal of the Custodian and each appointment of a successor Custodian by mailing written notice of such event by first class mail, postage prepaid, to all Holders as their names and addresses appear in the Unit Register. Each notice shall include the name of the successor Custodian and the address of its Corporate Trust Office.

(g) Upon the appointment of a successor Custodian pursuant to this Article, the predecessor Custodian shall immediately deliver to the successor Custodian any remaining portion of the compensation and expenses received in advance by the predecessor Custodian pursuant to either Section 3.05 or this Section 3.07(g). The amount of compensation and expenses the predecessor Custodian shall deliver will be determined by multiplying the total amount received by the predecessor Custodian, pursuant to either Section 3.05 or this Section 3.07(g), by a fraction, which numerator is the number of days remaining until the Purchase Contract Settlement Date and which denominator is the number of days remaining until the Purchase Contract Settlement Date plus the number of days such predecessor Custodian has performed the duties hereunder.

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

Section 3.10. Merger, Conversion, Consolidation or Succession to Business. Any corporation into which the Custodian 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 Custodian shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of the Custodian, shall be the successor of the Custodian hereunder, provided such corporation 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.
