The Company will determine LIBOR for each Floating Rate Interest Period in accordance with the following provisions: (i) On each Interest Determination Date, the Company will ascertain the offered rate for three-month deposits in U.S. dollars in the London interbank market, which appears on the Telerate Page 3750 as of 11:00 a.m. (London time) on such Interest Determination Date.

If at least two such quotations are provided, LIBOR in respect of that interest determination date will be the arithmetic mean of such quotations. (iii) If less than two of the Reference Banks provide the Company with such offered quotations, LIBOR in respect of that Interest Determination Date will be the arithmetic mean of the rates quoted by three major banks in The City of New York selected by the Company at approximately 11:00 a.m., New York City time, on that Interest Determination Date for three-month loans in U.S. dollars to leading European banks, in a principal amount equal to an amount of not less than $1 million that is representative for a single transaction in such market at such time; provided, however, that if the banks the Company so selected are not quoting as mentioned in this sentence, LIBOR will be LIBOR in effect on such Interest Determination Date. The interest payable on each Floating Rate Interest Payment Date shall be the amount of interest accrued from August 31, 1999 or from the most recent Floating Rate Interest Payment Date to which interest has been paid or duly provided for, as the case may be, until the principal amount of the Notes has been paid or duly provided for. Interest on the Notes will be calculated on the basis of the actual number of days in the applicable Floating Rate Interest Period divided by 360. The interest payable on any Note which is punctually paid or duly provided for on any Floating Rate Interest Payment Date shall be paid to the Person in whose name such Note is registered at the close of business on February 18, May 21, August 21 and November 20 (in each case, whether or not a Business Day), respectively, immediately preceding such Floating Rate Interest Payment Date (each, a "Regular Record Date"). Interest payable on any Note which is not punctually paid or duly provided for on any Floating Rate Interest Payment Date therefor shall forthwith cease to be payable to the Person in whose name such Note is registered at the close of business on the Regular Record Date immediately preceding such Floating Rate Interest Payment Date, and such interest shall instead be paid to the Person in whose name such Note is registered at the close of business on the record date established for such payment by notice by or on behalf of the Company to the Holders of the Notes mailed by first-class mail not less than 5 15 days prior to such record date to their last addresses as they shall appear upon the Security register, such record date to be not less than five days preceding the date of payment of such defaulted interest.
