Borrower acknowledges that interest calculated on an Actual/360 Basis exceeds interest calculated on a 30/360 Basis and, therefore; (a) a greater portion of each monthly installment of principal and interest will be applied to interest using the Actual/360 Basis than would be the case if interest accrued on a 30/360 Basis; and (b) the unpaid principal balance of this Note on the Maturity Date will be greater using the Actual/360 Basis than would be the case if interest accrued on a 30/360 Basis. 4.5 APPLICATION OF PAYMENTS. In the absence of a specific determination by Lender to the contrary, all payments paid by Borrower to Lender in connection with the obligations of Borrower under this Note and under the other Loan Documents shall be applied in the following order of priority: (a) to amounts, other than principal and interest due to Lender pursuant to this Note or the other Loan Documents; (b) to accrued but unpaid interest on this Note; and (c) to the unpaid principal balance of this Note. Borrower irrevocably waives the right to direct the application of any and all payments at any time hereafter received by Lender from or on behalf of Borrower, and Borrower irrevocably agrees that Lender shall have the continuing exclusive right to apply any and all such payments against the then due and owing obligations of Borrower in such order of priority as Lender may deem advisable. 5. LATE CHARGE; DEFAULT RATE. 5.1 LATE CHARGE. If all or any portion of any payment or deposit required hereunder (other than the payment due on the Maturity Date) is not paid or deposited on or before the fourth day following the day on which such payment or deposit is due, Borrower shall pay a late or collection charge, as liquidated damages, equal to 5% of the amount of such unpaid payment or deposit. If all or any portion of the payment due on the Maturity Date is paid more than 4 days after the Maturity Date and on a date other than the first day of a month. Borrower shall pay a late or collection charge, as liquidated damages, equal to the interest which would have accrued on such amount during the period commencing on the date payment of such amount is actually made and ending on the last day of the month in which payment of such amount is actually made. Borrower acknowledges that Lender will incur additional expenses as a result of any late payments or deposits hereunder, which expenses would be impracticable to quantify, and that Borrower's payments under this Section 5.1 are a reasonable estimate of such expenses. 5.2 DEFAULT RATE. Commencing upon a Default and continuing until such Default shall have been cured by Borrower, all sums owing on this Note shall bear interest until paid in full at an annual rate equal to 5% plus the Interest Rate, but not higher than the maximum rate of interest permitted by applicable law ("Default Rate"). 6. MAXIMUM RATE PERMITTED BY LAW. Neither this Note nor any of the other Loan Documents shall require the payment or permit the collection of any Interest or any late payment charge in excess of the maximum rate permitted by law. If any such excess interest or late payment charge is provided for under this Note or any of the other Loan Documents or if this Note or any of the other Loan Documents shall be adjudicated to provide for such excess, neither Borrower nor Borrower's successors or assigns shall be obligated to pay such excess, and the right to demand the payment of any such excess shall be and hereby is waived, and this provision shall control any other provision of this Note or any of the other Loan Documents. If Lender shall collect amounts which are deemed to constitute interest and which would increase the effective interest rate to a rate in excess of the maximum rate permitted by law, all such amounts deemed to constitute interest in excess of the maximum legal rate shall, upon such determination, at the option of Lender, be returned to Borrower or credited against the outstanding principal balance of this Note. 7. ACCELERATION. If (a) Borrower shall fail to pay when due any sums payable under this Note; (b) any other Default shall occur, or (c) any other event or condition shall occur which, under the terms of the Deed of Trust or any other Loan Document, gives rise to a right of acceleration of sums owing under this Note, then Lender, at its sole option, shall have the right to declare all sums owing under this Note immediately due and payable; provided, however, that if the Deed of Trust or any other Loan Document provides for the automatic acceleration of payment of sums owing under this Note, all sums owing under this Note shall be automatically due and payable in accordance with the terms of the Deed of Trust or such other Loan Document. 3 <Page> 8.

ADDITIONAL TERMS AND CONDITIONS. The additional terms and conditions set forth in EXHIBIT A attached hereto are incorporated herein by this reference. 13. PREPAYMENT - DEFEASANCE ONLY. Borrower acknowledges that any prepayment of this Note will cause Lender to lose its interest rate yield on this Note and will possibly require that Lender reinvest any such prepayment amount in loans of a lesser interest rate yield (including, without limitation, in debt obligations other than first mortgage loans on commercial properties). As a consequence, Borrower agrees as follows, as an integral part of the consideration for Lender's making the Loan: 13.1 VOLUNTARY PREPAYMENT. Any voluntary prepayment of this Note: (a) is prohibited except during the last 6 months of the term, and (b) is permitted in full only, and not in part. 13.2 PREPAYMENT CHARGE. a. BASIC CHARGE. Except as provided below, if this Note is prepaid prior to the last 6 months of the term, whether such prepayment is involuntary or upon acceleration of the principal amount of this Note by Lender following a Default, Borrower shall pay to Lender on the prepayment date (in addition to all other sums then due and owing to Lender under the Loan Documents) a prepayment charge equal to the greater of the following two amounts: (i) an amount equal to 1% of the amount prepaid; or (ii) an amount equal to (a) the amount, if any, by which the sum of the present values as of the prepayment date of all unpaid principal and interest payments required under this Note, calculated by discounting such payments from their respective scheduled payment dates back to the prepayment date at a discount rate equal to the Periodic Treasury Yield (defined below) exceeds the outstanding principal balance of the Loan as of the prepayment date, multiplied by (b) a fraction whose numerator is the amount prepaid and whose denominator is the outstanding principal balance of the Loan as of the prepayment date. For purposes of the foregoing, "Periodic Treasury Yield" means (iii) the annual yield to maturity of the actively traded non-callable United States Treasury fixed interest rate security (other than any such security which can be surrendered at the option of the holder at face value in payment of federal estate tax or which was issued at a substantial discount) that has a maturity closest to (whether before, on or after) the Maturity Date (or if two or more such securities have maturity dates equally close to the Maturity Date, the average annual yield to maturity of all such securities), as reported in The Wall Street Journal or other authoritative publication or news retrieval service on the fifth Business Day preceding the prepayment date, divided by (iv) 12, if scheduled payment dates are monthly, or 4, if scheduled payment dates are quarterly. b. ADDITIONAL CHARGE. If this Note is prepaid on any day other than the first day of a month, whether such prepayment is voluntary, involuntary or upon full acceleration of the principal amount of this Note by Lender following a Default, Borrower shall pay to Lender on the prepayment date (in addition to the basic prepayment charge described in Section 13.2.a above and all other sums then due and owing to Lender under this Note and the other Loan Documents) an additional prepayment charge equal to the interest which would otherwise have accrued on the amount prepaid (had such prepayment not occurred) during the period commencing on the prepayment date and ending on the last day of the month in which the prepayment occurred. 6 <Page> c. EXCLUSION. Notwithstanding the foregoing, no prepayment charge of any kind shall apply in respect to any prepayment resulting from Lender's application of any insurance proceeds or condemnation awards to the outstanding principal balance of the Loan. 13.3 EFFECT OF PREPAYMENT. No partial prepayment of this Note shall change the dates or amounts of subsequent monthly installments of principal and interest, unless Lender otherwise agrees in writing. 13.4 WAIVER. Borrower waives any right to prepay this Note except under the terms and conditions set forth in this Section 13 and agrees that if this Note is prepaid, Borrower shall pay the prepayment charge set forth above. Borrower hereby acknowledges that: (a) the inclusion of this waiver of prepayment rights and agreement to pay the prepayment charge for the right to prepay this Note was separately negotiated with Lender; (b) the economic value of the various elements of this waiver and agreement was discussed; (c) the consideration given by Borrower for the Loan was adjusted to reflect the specific waiver and agreement negotiated between Borrower and Lender and contained herein; and (d) this waiver is intended to comply with California Civil Code Section 2954.10.
