2.             Calculations and Information Provided.  In response to a request made by the Trustee for a determination of the Repayment Amount with respect to any series of the Notes, the Calculation Agent shall determine the Repayment Amount (as set forth below) on the Valuation Date (as defined below) in accordance with the terms of the Notes and this Agreement and notify the Trustee of its determination.  In addition, the Calculation Agent shall also be responsible for determining each of the following items for the Notes, to the extent applicable:

(a)           whether a Market Disruption Event (as defined below) has occurred;

(b)           the applicable Valuation Date for any Basket Currency; and

(c)           any other calculation, determination or adjustment specified as being made by the Calculation Agent in this Agreement, the relevant Pricing Supplement or the Notes.

3.             Calculations.  Any calculation or determination by the Calculation Agent pursuant hereto shall be made at the sole discretion of the Calculation Agent and shall (in the absence of manifest error) be final and binding.  Any calculation made by the Calculation Agent hereunder shall, at the Trustee’s request, be made available at the Corporate Trust Office. The procedures the Calculation Agent will use to determine the information described herein with respect to the Notes is set forth as follows:

(a)           On the Valuation Date, the Calculation Agent shall calculate the Repayment Amount for the Notes. The Repayment Amount, for each $1 principal amount of the Notes, is the amount equal to the sum of (a) $1 plus (b) the Additional Amount.

(i)            The “Additional Amount”, for each $1 principal amount of the Notes, equals 125% times the greater of (i) zero and (ii) the difference between the Final Basket Value minus the Initial Basket Value.

(ii)           The “Initial Basket Value” equals $1.

(iii)          The “Final Basket Value” equals the sum of:

a.               a quotient, the numerator of which is 7.8570 and the denominator of which is the Final Currency Value for Indian Rupee (“INR”) plus

b.              a quotient, the numerator of which is 19.8000 and the denominator of which is the Final Currency Value for Japanese Yen (“JPY”) plus

c.               a quotient, the numerator of which is 185.1300 and the denominator of which is the Final Currency Value for Korean Won (“KRW”) plus

d.              a quotient, the numerator of which is 7.3746 and the denominator of which is the Final Currency Value for Thai Baht (“TWD”) plus

e.               a quotient, the numerator of which is 5.7852 and the denominator of which is the Final Currency Value for Taiwanese Dollar (“TWD”) plus

f.                  a quotient, the numerator of which is 0.810120 and the denominator of which is the Final Currency Value for Chinese Yuan (“CNY”).

(iv)          The “Final Currency Value” equals the value of each Basket Currency represented by the spot exchange rate between the applicable Basket Currency and the U.S. Dollar expressed as the amount of Basket Currency per U.S. Dollar for customary settlement in the interbank market for each Basket Currency on the Valuation Date, as reported by Reuters on the applicable page, or any substitute page, and at the approximate time set forth in the following table:

2

The “Valuation Date” is, with respect to any Basket Currency, the latest Currency Business Day for that Basket Currency that is at least two Business Days prior to August 31, 2007, subject to postponement in the event of a Market Disruption Event.

A “Currency Business Day” is, with respect to any Basket Currency, any day, other than a Saturday or Sunday, that is neither a legal holiday nor a day on which commercial banks are authorized or required by law, regulation or executive order to close (including for dealings in foreign exchange in accordance with the practice of the foreign exchange market) in the city listed above under “Applicable Currency Business Day” for that Basket Currency.

A “Business Day”, notwithstanding any provision in the Indenture, is any day that is not is not a Saturday or Sunday and that is not a day on which banking institutions in New York City generally are authorized or obligated by law or executive order to be closed.

(b)           If no spot quotation is available for a Basket Currency from the applicable Reuters page described under “Final Currency Value” above or there occurs an event that generally makes it impossible to convert any of the Basket Currencies into U.S. dollars through customary legal channels, or to obtain a firm quote of any of the exchange rates between the Basket Currencies and the U.S. dollar on the Valuation Date, that, in the good faith determination of the Calculation Agent, affects the valuation of the Final Basket Value or the Company’s ability or any similarly situated party to hedge its exposure or to unwind all or a material portion of a hedge with respect to this Note (“Market Disruption Event”), then the Valuation Date for that Basket Currency will be postponed to the next succeeding Currency Business Day for that Basket Currency; provided, that if the Final Currency Value for any Basket Currency is not capable of calculation as of the next succeeding Currency Business Day because of an occurring or continuing Market Disruption Event, the Calculation Agent will determine the Final Currency Value for that Basket Currency taking into consideration all available information that in good faith it deems relevant.

(c)           The Calculation Agent shall notify the Trustee of all such calculations, determinations and adjustment or if a Market Disruption Event with respect to a series of Notes has occurred.
