Notwithstanding the foregoing, in no event shall the LIBO-Rate be less than zero.

“Prime Rate” shall mean the rate of interest per annum publicly announced from time to time by HSBC as its prime rate in effect at its office located at 452 Fifth Avenue, New York, New York; each change in the Prime Rate shall be effective from and including the date such change is publicly announced.

“Reference Banks” shall mean three or more Lenders selected by the Administrative Agent with the consent of Parent (whose consent shall not be required if an Event of Default shall have then occurred and be continuing). .

“Reference Bank Rate” shall mean the arithmetic mean of the rates (rounded upwards to four decimal places) as supplied to the Administrative Agent at its request by the Reference Banks as the rate at which the relevant Reference Bank could borrow funds in the London interbank market in the relevant currency and for the relevant Interest Period, were it to do so by asking for and then accepting interbank offers for deposits in reasonable market size in that currency and for that Interest Period, provided that, if any of the Reference Banks fail to provide a rate to the Administrative Agent, the Reference Bank Rate will be determined based on the rates provided by those Reference Banks that do supply a rate.
