DEFINITIONS:

As used herein, the following terms shall have the meanings set forth after each, and any other term defined in this Note shall have the meaning set forth at the place defined:

(b)       "LIBOR" means the rate of interest per annum determined by Bank based on the rate for United States dollar deposits for delivery of funds for one (1) month as published by the ICE Benchmark Administration Limited, a United Kingdom company, at approximately 11:00 a.m., London time, or, for any day not a London Business Day, the immediately preceding London Business Day (or if not so published, then as determined by Bank from another recognized source or interbank quotation); provided, however, that if LIBOR determined as provided above would be less than zero percent (0.0%), then LIBOR shall be deemed to be zero percent (0.0%).

(c)       "London Business Day" means any day that is a day for trading by and between banks in dollar deposits in the London interbank market.

INTEREST:

(a)       Interest. The outstanding principal balance of this Note shall bear interest (computed on the basis of a 360-day year, actual days elapsed) at a fluctuating rate per annum determined by Bank to be two and twenty-five hundredths of one percent (2.25%) above Daily One Month LIBOR in effect from time to time. Bank is hereby authorized to note the date and interest rate applicable to this Note and any payments made thereon on Bank's books and records (either manually or by electronic entry) and/or on any schedule attached to this Note, which notations shall be prima facie evidence of the accuracy of the information noted.
