WHEREAS, the parties hereto acknowledge that the Trust Documents in general, and the provisions of Section 2.04(a) of the Standard Terms in particular, require the Trustee to adjust the composition of the Portfolio from time to time to conform, to the extent practicable, to changes in the composition and/or price weightings of the Index Securities; and

WHEREAS, the parties hereto acknowledge that the terms of Section 2.04 of the Standard Terms require the Trustee to adjust the composition of the Trust’s Portfolio any time that there is a change in the identity of any Index Security (such as substitution of one security in replacement of another or a stock split) within 3 Business Days before or after the day on which the change in the identity of such Index Security is scheduled to take effect at the close of the market; and

WHEREAS, the parties hereto acknowledge that the terms of Section 2.04 of the Standard Terms (1) permit the Trustee to take account of stock splits and other corporate actions by adjusting the composition of the Portfolio Deposit on the day prior to the effective day of the adjustment to the Index but (2) require the Trustee to take account of changes in the identity of any Index Security by adjusting the composition of the Trust’s Portfolio Deposit following the effective day of the adjustment to the Index; and

WHEREAS, the parties hereto intend that all adjustments made to the Portfolio, the Portfolio Securities and the Portfolio Deposits shall be effected by the Trustee so as to conform the composition and security weightings of the Portfolio, to the fullest extent practicable, to the composition and security weightings of the Index Securities in the Index; and
