ADDITIONAL TERMS OF THE NOTES

Calculation of the Interest Rate for the Notes. The amount of interest payable on the Notes on each Interest Payment Date will be equal to the weighted average of the Federal Funds Open Rate (as defined below) plus the Spread set forth above.

Federal Funds Open Rate. The Federal Funds Open Rate for any Interest Determination Date will be determined in the following order of priority:

	(1)		The Federal Funds Open Rate for an Interest Determination Date will be the rate for that day under the heading “Federal Funds” and opposite the caption “Open” as such rate is displayed on Telerate Page 5; or
	(2)		If the rate referred to in item (1) above does not appear on Telerate Page 5 on the related calculation date, the rate for such Interest Determination Date will be the rate for that day displayed on FEDFOPEN Index on Bloomberg which is the Fed Funds Opening Rate as reported by Garban Capital Markets (or a successor) on Bloomberg; or
	(3)		If the rate referred to in item (2) above does not appear on FEDFOPEN Index on Bloomberg, the rate for such Interest Determination Date will be the arithmetic mean of the rates for the last transaction in overnight U.S. Dollar Federal Funds prior to 9:00 a.m., New York City time, on that day arranged by three brokers of Federal Funds transactions in New York City as selected by the Calculation Agent.

The Federal Funds Open Rate will be calculated on a weighted basis, meaning Friday’s rate will be in effect for Saturday and Sunday.
