The Borrower may elect to have all or portions of the principal balance of the line of credit bear interest at the Fixed Rate, subject to the following requirements: (a)	The "Fixed Rate" means the fixed interest rate the Bank and the Borrower agree will apply to the portion during the applicable interest period.

(f)	Each prepayment of a Fixed Rate portion, whether voluntary, by reason of acceleration or otherwise, will be accompanied by the amount of accrued interest on the amount prepaid, and a prepayment fee equal to the amount (if any) by which: (i)	the additional interest which would have been payable on the amount prepaid had it not been paid until the last day of the interest period, exceeds (ii)	the interest which would have been recoverable by the Bank by placing the amount prepaid on deposit in the certificate of deposit market for a period starting on the date on which it was prepaid and ending on the last day of the interest period for such portion. 1.7	LIBOR Rate.

(All amounts in the calculation will be determined by the Bank as of the first day of the interest period.) LIBOR Rate = 	 London Rate (1.00 - Reserve Percentage) 	Where, (i) 	"London Rate" means the interest rate (rounded upward to the nearest 1/16th of one percent) at which the Bank's London Branch, London, Great Britain, would offer U.S. dollar deposits for the applicable interest period to other major banks in the London inter-bank market at approximately 11:00 a.m. London time two (2) banking days before the commencement of the interest period.

A "prepayment" is a payment of an amount on a date earlier than the scheduled payment date for such amount as required by this Agreement. The prepayment fee shall be equal to the amount (if any) by which: (i)	the additional interest which would have been payable during the interest period on the amount prepaid had it not been prepaid, exceeds (ii)	the interest which would have been recoverable by the Bank by placing the amount prepaid on deposit in the London inter-bank market for a period starting on the date on which it was prepaid and ending on the last day of the interest period for such portion (or the scheduled payment date for the amount prepaid, (if earlier).

Except as otherwise stated in this Agreement, all interest and fees, if any, will be computed on the basis of a 360-day year and the actual number of days elapsed. This results in more interest or a higher fee than if a 365-day year is used. 4.9	Interest on Late Payments. At the Bank's sole option in each instance, any amount not paid when due under this Agreement (including interest) shall bear interest from the due date at the Bank's Reference Rate minus .5 percentage point.

However, if the controversy or claim arises from or relates to an obligation to the Bank which is secured by real property located in California at the time of the proposed submission to arbitration, this right is limited according to the provision above requiring the consent of both the Borrower and the Bank to seek resolution through arbitration. (j)	If the Bank forecloses against any real property securing this Agreement, the Bank has the option to exercise the power of sale under the deed of trust or mortgage, or to proceed by judicial foreclosure. 9.5	Severability; Waivers.
