Schedule A

DETERMINATION OF LIBOR

With respect to the Securities, the London interbank offered rate (“LIBOR”) shall be determined by the Calculation Agent in accordance with the following provisions (in each case rounded to the nearest .000001%):

(1) On the second LIBOR Business Day (as defined below) prior to an Interest Payment Date (except, with respect to the first interest payment period, on October 27, 2006) (each such day, a “LIBOR Determination Date”), LIBOR for any given security shall, for the following interest payment period, equal the rate, as obtained by the Calculation Agent from Bloomberg Financial Markets Commodities News, for three-month U.S. Dollar deposits in Europe, which appears on Dow Jones Telerate Page 3750 (as defined in the International Swaps and Derivatives Association, Inc. 1991 Interest Rate and Currency Exchange Definitions), or such other page as may replace such Page 3750, as of 11:00 a.m. (London time) on such LIBOR Determination Date.

(2) If, on any LIBOR Determination Date, such rate does not appear on Dow Jones Telerate Page 3750 or such other page as may replace such Page 3750, the Calculation Agent shall determine the arithmetic mean of the offered quotations of the Reference Banks (as defined below) to leading banks in the London interbank market for three-month U.S. Dollar deposits in Europe in an amount determined by the Calculation Agent by reference to requests for quotations as of approximately 11:00 a.m. (London time) on the LIBOR Determination Date made by the Calculation Agent to the Reference Banks. If, on any LIBOR Determination Date, at least two of the Reference Banks provide such quotations, LIBOR shall equal such arithmetic mean of such quotations. If, on any LIBOR Determination Date, only one or none of the Reference Banks provide such quotations, LIBOR shall be deemed to be the arithmetic mean of the offered quotations that leading banks in the City of New York selected by the Calculation Agent are quoting on the relevant LIBOR Determination Date for three-month U.S. Dollar deposits in Europe in an amount determined by the Calculation Agent by reference to the principal London offices of leading banks in the London interbank market; provided that, if the Calculation Agent is required but is unable to determine a rate in accordance with at least one of the procedures provided above, LIBOR shall be LIBOR as determined on the previous LIBOR Determination Date.

(3) As used herein: “Reference Banks” means four major banks in the London interbank market selected by the Calculation Agent; and “LIBOR Business Day” means a day on which commercial banks are open for business (including dealings in foreign exchange and foreign currency deposits) in London.
