Interest Reset Periods

The “initial interest period” will be the period from and including the original issue date to but excluding the initial interest reset date. Thereafter, each “interest reset period” will be the period from and including an interest reset date to but excluding the immediately succeeding interest reset date; provided that the final interest reset period will be the period from and including the interest reset date immediately preceding the maturity date to but excluding the maturity date.

Interest Rate Determination

The interest rate applicable to each interest reset period commencing on the related interest reset date, or the original issue date in the case of the initial interest period, will be the rate determined as of the applicable interest determination date. The “interest determination date” will be the second London business day immediately preceding the original issue date in the case of the initial interest reset period, and thereafter the second London business day immediately preceding the applicable interest reset date. The interest rate in effect on each day will be (i) if that day is an interest reset date, the interest rate determined as of the interest determination date immediately preceding such interest reset date or (ii) if that day is not an interest reset date, the interest rate determined as of the interest determination date immediately preceding the most recent interest reset date or the original issue date, as the case may be. 3-month LIBOR will be determined by the calculation agent as of the applicable interest determination date in accordance with the following provisions: (i) LIBOR is the rate for deposits in U.S. dollars for the 3-month period which appears on Reuters Screen LIBOR01 Page (as defined below) at approximately 11:00 a.m., London time, on the applicable interest determination date. “Reuters Screen LIBOR01 Page” means the display designated on page “LIBOR01” on Reuters Screen (or such other page as may replace the LIBOR01 page on that service, any successor service or such other service or services as may be nominated by the British Bankers’ Association for the purpose of displaying London interbank offered rates for U.S. dollar deposits). If no rate appears on Reuters Screen LIBOR01 Page, LIBOR for such interest determination date will be determined in accordance with the provisions of paragraph (ii) below. (ii) With respect to an interest determination date on which no rate appears on Reuters Screen LIBOR01 Page as of

approximately 11:00 a.m., London time, on such interest determination date, the calculation agent shall request the principal London offices of each of four major reference banks (which may include affiliates of the underwriters) in the London interbank market selected by the calculation agent (after consultation with the Company) to provide the calculation agent with a quotation of the rate at which deposits of U.S. dollars having a three-month maturity, commencing on the second London business day immediately following such interest determination date, are offered by it to prime banks in the London interbank market as of approximately 11:00 a.m., London time, on such interest determination date in a principal amount equal to an amount of not less than U.S. $1,000,000 that is representative for a single transaction in such market at such time. If at least two such quotations are provided, LIBOR for such interest determination date will be the arithmetic mean of such quotations as calculated by the calculation agent. If fewer than two quotations are provided, LIBOR for such interest determination date will be the arithmetic mean of the rates quoted as of approximately 11:00 a.m., New York City time, on such interest determination date by three major banks (which may include affiliates of the underwriters) selected by the calculation agent (after consultation with the Company) for loans in U.S. dollars to leading European banks having a three-month maturity commencing on the second London business day immediately following such interest determination date and in a principal amount equal to an amount of not less than U.S. $1,000,000 that is representative for a single transaction in such market at such time; provided, however, that if the banks selected as aforesaid by the calculation agent are not quoting such rates as mentioned in this sentence, LIBOR for such interest determination date will be LIBOR determined with respect to the immediately preceding interest determination date.

All percentages resulting from any calculation of any interest rate will be rounded, if necessary, to the nearest one hundred thousandth of a percentage point, with five one-millionths of a percentage point rounded upward (e.g., 9.876545% (or .09876545) would be rounded to 9.87655% (or .0987655)), and all dollar amounts will be rounded to the nearest cent, with one-half cent being rounded upward.

Promptly upon such determination, the calculation agent will notify the Company and the trustee (if the calculation agent is not the trustee) of the interest rate for the new interest reset

	period. Upon request of a holder, the calculation agent will provide to such holder the interest rate in effect on the date of such request and, if determined, the interest rate for the next interest reset period. All calculations made by the calculation agent for the purposes of calculating interest shall be conclusive and binding on the holders and the Company, absent manifest errors.
Business Day	With respect to the Floating Rate Notes, “business day” means any day (1) that is not a Saturday or Sunday and that is not a day on which banking institutions are authorized or obligated by law or executive order to close in The City of New York and, for any place of payment outside of The City of New York, in such place of payment, and (2) that is also a “London business day”, which is a day on which dealings in deposits in U.S. dollars are transacted in the London interbank market.
