designated by the Administrative Agent from time to time) for a term equivalent
to such Interest Period (or if such Interest Period is not equal to a number of
months, for a term equivalent to the number of months closest to such Interest
Period); and if such rates are not available on the Reuters Screen CDOR Page (or
any such other display or page) on any particular day, then the CDOR Rate on
that day shall be calculated as the rate applicable to Canadian Dollar

such date for deposits in the relevant currency with a term equivalent to one
(1) month; provided, that if such rate is not available at such time for any

Agent from time to time) at approximately 11:00 a.m., London time, two Business
Days prior to the commencement of such Interest Period, for deposits in the

Period; and

(ii)    for any Interest Period with respect to a Eurodollar Rate Loan
