The Chase Manhattan Bank will compute the Applicable LIBOR Rate and the interest rate on the PURS until September 28, 2000. The Applicable LIBOR Rate means the rate for deposits in U.S. dollars having the Relevant Maturity that appears on the Telerate page 3750 as of 11:00 A.M., London time, on the second day on which dealings in U.S. dollars are transacted in the London interbank market preceding October 28, 1999, January 28, 2000, April 28, 2000, July 28, 2000 and September 28, 2000, as the case may be. The Relevant Maturity for the interest period beginning on September 28, 1999 will be one month; the Relevant Maturity for the interest period beginning on October 28, 1999, January 28, 2000 and April 28, 2000 will be three months; and the Relevant Maturity for the interest period beginning on July 28, 2000 will be two months.

If the Applicable LIBOR Rate on an interest determination date does not appear on the Telerate page 3750, the Applicable LIBOR Rate will be determined by The Chase Manhattan Bank on the basis of the rates at which deposits in U.S. dollars are offered by four major banks in the London interbank market selected by The Chase Manhattan Bank at approximately 11:00 A.M., London time, on that interest determination date to prime banks in the London interbank market having the relevant maturity 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 that market at that -5- time. The Chase Manhattan Bank will request the principal London office of each of those four major banks to provide a quotation of its rate. If at least two quotations are provided, the Applicable LIBOR Rate will be the arithmetic mean (rounded, if necessary, to the nearest one hundred-thousandth of a percentage point, with five one-millionths of a percentage point rounded upwards) of those quotations. If fewer than two quotations are provided, the Applicable LIBOR Rate will be the arithmetic mean (rounded, if necessary, to the nearest one hundred-thousandth of a percentage point, with five one-millionths of a percentage point rounded upwards) of the rates quoted by three major banks in New York City selected by The Chase Manhattan Bank at approximately 11:00 A.M., New York City time, on the interest determination date for loans in U.S. dollars to leading European banks, having the Relevant Maturity 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 that market at that time. If the banks in New York City selected by The Chase Manhattan Bank are not quoting rates as mentioned above on the interest determination date, then the Applicable LIBOR Rate for the subsequent interest period will be the Applicable LIBOR Rate in effect on the interest determination date.
