The Lender will notify the Borrower that the Lender is entitled to compensation pursuant to this Section 5.01(c) as promptly as practicable after it determines to request such compensation.

Upon delivery of the notice referred to in the immediately preceding sentence, the Base Rate Loan shall automatically convert back to a Eurodollar Loan with an Interest Period of one month, beginning on the date of conversion. If the Lender requests additional compensation under Section 5.01, the Borrower shall have the right, if no Event of Default then exists, to convert each of the Eurodollar Loans to a Base Rate Loan on the last day of such Eurodollar Loan's current Interest Period, upon payment of all such compensation accrued to the date of such conversion. Section 5.05 Compensation. The Borrower shall pay to the Lender within thirty (30) days of receipt of written request of the Lender (which request shall set forth, in reasonable detail, the basis for requesting such amounts and which shall be conclusive and binding for all purposes provided that such determinations are made on a reasonable basis), such amount or amounts as shall compensate it for any funding losses or other loss, cost, expense or liability which the Lender may sustain as a result of any prepayment of the Eurodollar Loans for any reason (including, without limitation, the acceleration of the Loans pursuant to Section 8.02) on any day other than the last day of the applicable Interest Period.

Section 9.14 Interest. It is the intention of the parties hereto that the Lender shall conform strictly to usury laws applicable to it. Accordingly, if the transactions contemplated hereby would be usurious as to the Lender under laws applicable to it (including the laws of the United States of America or any other jurisdiction whose laws may be mandatorily applicable to the Lender notwithstanding the other provisions of this Agreement), then, in that event, notwithstanding anything to the contrary in this Agreement or the Note or any agreement entered into in connection with or as security for the Note, it is agreed as follows: (i) the aggregate of all consideration which constitutes interest under law applicable to the Lender that is contracted for, taken, reserved, charged or received by the Lender in connection with the Note shall under no circumstances exceed the maximum amount allowed by such applicable law, and any excess shall be canceled automatically and if theretofore paid shall be credited by the Lender on the principal amount of the Loans (or, to the extent that the principal amount of the Loans shall have been or would thereby be paid in full, refunded by the Lender to the Borrower); and (ii) in the event that the maturity of the Note is accelerated by reason of an election of the holder thereof resulting from any Event of Default under this Agreement or otherwise, or in the event of any required or permitted prepayment, then such consideration that constitutes interest under law applicable to the Lender may never include more than the maximum amount allowed by such applicable law, and excess interest, if any, provided for in this Agreement or otherwise shall be canceled automatically by the Lender as of the date of such acceleration or prepayment and, if theretofore paid, shall be credited by the Lender on the principal amount of the Loans (or, to the extent that the principal amount of the Loans shall have been or would thereby be paid in full, refunded by the Lender to the Borrower). All sums paid or agreed to be paid to the Lender for the use, forbearance or -26- 31 detention of sums due hereunder shall, to the extent permitted by law applicable to the Lender, be amortized, prorated, allocated and spread throughout the full term of the Loans evidenced by the Note until payment in full so that the rate or amount of interest on account of the Loans hereunder does not exceed the maximum amount allowed by such applicable law. If at any time and from time to time (i) the amount of interest payable to the Lender on any date shall be computed at the Highest Lawful Rate applicable to the Lender pursuant to this Section 9.14 and (ii) in respect of any subsequent interest computation period the amount of interest otherwise payable to the Lender would be less than the amount of interest payable to the Lender computed at the Highest Lawful Rate applicable to the Lender, then the amount of interest payable to the Lender in respect of such subsequent interest computation period shall continue to be computed at the Highest Lawful Rate applicable to the Lender until the total amount of interest payable to the Lender shall equal the total amount of interest which would have been payable to the Lender if the total amount of interest had been computed without giving effect to this Section 9.14.
