Borrower understands and agrees that Bank may                base its                quotation of the Inter-Bank Market Offered Rate upon such offers                or other                marked indicators of the Inter-Bank Market as Bank in its discretion                deems                appropriate including, but not limited to, the rate offered for U.S.                dollar deposits on the London Inter-Bank                Market. |

|--------|-----|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | 2.2 | **Selection                of Interest Rate Options**.                At any time any portion of this Note bears interest determined in                relation                to Bank’s LIBOR, it may be continued by Borrower at the end of the Fixed                Rate Term applicable thereto so that all or a portion thereof bears                interest determined in relation to the Prime Rate or in relation                to Bank’s                LIBOR for a new Fixed Rate Term designated by Borrower. At any time                any                portion of this Note bears interest determined in relation to the                Prime                Rate, Borrower may convert all or a portion thereof so that it bears                interest determined in relation to Bank’s LIBOR for a Fixed Rate Term                designated by Borrower. At the time each advance is requested hereunder                or                Borrower wishes to select the LIBOR option for all or a portion of                the                outstanding principal balance hereof, and at the end of each Fixed                Rate                Term, Borrower shall give Trade Bank notice specifying (a) the interest                rate option selected by Borrower, (b) the principal amount subject                thereto, and (c) if the LIBOR option is selected, the length of the                applicable Fixed Rate Term. Any such notice may be given by telephone                so                long as, with respect to each LIBOR selection, (i) Trade Bank receives                written confirmation from Borrower not later than three (3) Business                Days                after such telephone notice is given, and (ii) such notice is given                to                Trade Bank prior to 10:00 a.m. California time, on the first day                of the                Fixed Rate Term. If Borrower does not immediately accept the rate                quoted                by Trade Bank, any subsequent acceptance by Borrower shall be subject                to a                redetermination by Trade Bank of the applicable fixed rate; provided                however, that if Borrower fails to accept any such rate by 11:00                a.m.,                California time, on the Business Day such quotation is given, then                the                quoted rate shall expire and Trade Bank shall have no obligation                to permit                a LIBOR option to be selected on such day. If no specific designation                of                interest is made at the time any advance is requested hereunder or                at the                end of any Fixed Rate Term, Borrower shall be deemed to have made                a Prime                Rate interest selection for such advance of the principal amount                to which                such Fixed Rate Term applied. |

If such notice                is                given and until such notice has been withdrawn by Trade Bank, than                (i) no                new LIBOR option may be selected by Borrower, and (ii) any portion                of the                outstanding principal balance hereof which bears interest determined                in                relation to Bank’s LIBOR, subsequent to the end of the Fixed Rate Term                applicable thereto, shall bear interest determined in relation to                the                Prime Rate. |

Upon the occurrence of any of the foregoing events, Borrower                shall pay to Trade Bank immediately upon demand such amounts as may                be                necessary to compensate Trade Bank for any fines, fees, charges,                penalties                or other costs incurred or payable by Trade Bank as a result thereof                and                which are attributable to an LIBOR options made available to Borrower                hereunder, and any reasonable allocation made by Trade Bank among                its                operations shall be conclusive and binding upon                Borrower. |

|   | (1) | Determine                the amount of interest which would have accrued each month on the                amount                prepaid at the interest rate applicable to such amount had it remained                outstanding until the last day of the Fixed Rate Term applicable                thereto. |
|--------|-----|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | (2) | Subtract                from the amount determined in (1) above the amount of interest which                would                have accrued for the same month on the amount prepaid for the remaining                term of such Fixed Rate Term at Bank’s LIBOR in effect on the date of                prepayment for new loans made for such term and in a principal amount                equal to the amount prepaid. |
|--------|-----|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | (3) | If                the result obtained in (2) for any month is greater than zero, discount                that difference by Bank’s LIBOR used in (2)                above. |
