The failure to exercise the option to accelerate the maturity of this Debenture or any other right, remedy or recourse available to the holder hereof upon the occurrence of an Event of Default hereunder shall not constitute a waiver of the right of the holder of this Debenture to exercise the same at that time or at any subsequent time with respect to such Event of Default or any other Event of Default. The rights, remedies and recourses of the holder hereof, as provided in this Debenture and in any of the other Loan Documents, shall be cumulative and concurrent and may be pursued separately, successively or together as often as occasion therefore shall arise, at the sole discretion of the holder hereof. The acceptance by the holder hereof of any payment under this Debenture which is less than the payment in full of all amounts due and payable at the time of such payment shall not (i) constitute a waiver of or impair, reduce, release or extinguish any right, remedy or recourse of the holder hereof, or nullify any prior exercise of any such right, remedy or recourse, or (ii) impair, reduce, release or extinguish the obligations of any party liable under any of the Loan Documents as originally provided herein or therein. This Debenture and all of the other Loan Documents and Related Agreements are intended to be performed in accordance with, and only to the extent permitted by, all applicable usury laws. If any provision hereof or of any of the other Loan Documents or Related Agreements or the application thereof to any person or circumstance shall, for any reason and to any extent, be invalid or unenforceable, neither the application of such provision to any other person or circumstance nor the remainder of the instrument in which such provision is contained shall be affected thereby and shall be enforced to the greatest extent permitted by law. It is expressly stipulated and agreed to be the intent of the holder hereof to at all times comply with the usury and other applicable laws now or hereafter governing the interest payable on the indebtedness evidenced by this Debenture. If the applicable law is ever revised, repealed or judicially interpreted so as to render usurious any amount called for under this Debenture or under any of the other Loan Documents, or contracted for, charged, taken, reserved or received with respect to the indebtedness evidenced by this Debenture, or if Lender's exercise of the option to accelerate the maturity of this Debenture, or if any prepayment by Borrower results in Borrower having paid any interest in excess of that permitted by law, then it is the express intent of Borrower and Lender that all excess amounts theretofore collected by Lender be credited on the principal balance of this Debenture (or, if this Debenture and all other indebtedness arising under or pursuant to the other Loan Documents have been paid in full, refunded to Borrower), and the provisions of this Debenture and the other Loan Documents and Related Documents immediately be deemed reformed and the amounts thereafter collectable hereunder and thereunder reduced, without the necessity of the execution of any new document, so as to comply with the then applicable law, but so as to permit the recovery of the fullest amount otherwise called for hereunder or thereunder. All sums paid, or agreed to be paid, by Borrower for the use, forbearance, detention, taking, charging, receiving or reserving of the indebtedness of Borrower to Lender under this Debenture or arising under or pursuant to the other Loan Documents and Related Agreements shall, to the maximum extent permitted by applicable law, be amortized, prorated, allocated and spread throughout the full term of such indebtedness until payment in full so that the rate or amount of interest on account of such indebtedness does not exceed the usury ceiling from time to time in effect and applicable to such indebtedness for so long as such indebtedness is outstanding. Notwithstanding anything to the contrary contained herein or in any of the other Loan Documents and Related Agreements, it is not the intention of Lender to accelerate the maturity of any interest that has not accrued at the time of such acceleration or to collect unearned interest at the time of such acceleration. AMENDED AND RESTATED DEBENTURE - PAGE 4 5 If this Debenture is placed in the hands of an attorney for collection, or is collected in whole or in part by suit or through probate, bankruptcy or other legal proceedings of any kind, Borrower agrees to pay, in addition to all other sums payable hereunder, all costs and expenses of collection, including but not limited to reasonable attorneys' fees.

If Borrower shall be required by law or the administration thereof to deduct or withhold any Taxes from or in respect of any sum payable with respect to this Debenture (i) the sum payable shall be increased as may be necessary so that after making all required deductions or withholdings (including deductions or withholdings applicable to additional amounts paid under this paragraph) such holder of this Debenture receives an amount equal to the sum it would have received if no such deduction or withholding had been made; (ii) Borrower shall make such deductions or withholdings; and (iii) Borrower shall forthwith pay the full amount deducted or withheld to the relevant taxation or other authority in accordance with applicable law. A "qualified assignee" of a holder of this Debenture is a person that is organized under the laws of (I) the United States or (II) any jurisdiction other than the United States or any political subdivision thereof and that (y) represents and warrants to Borrower that payments of Borrower to such assignee under applicable law would not be subject to any Taxes and (z) from time to time, as and when requested by Borrower, executes and delivers to Borrower and the Internal Revenue Service forms, and provides Borrower with any information, necessary to establish such assignee's continued exemption from Taxes under applicable law. Borrower shall forthwith pay any present or future stamp or documentary taxes or any other excise or property taxes, charges or similar levies (all such taxes, charges and levies hereinafter referred to as "Other Taxes") which arise from any payment made under this Debenture or the transactions contemplated hereby. Borrower shall indemnify each holder of this Debenture, or qualified assignee, for the full amount of Taxes or Other Taxes (including, without limitation, any Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this paragraph) paid by each holder of this Debenture, or qualified assignee, and any liability (including penalties, interest and expenses) arising therefrom or with respect thereto, whether or not such Taxes or Other Taxes were correctly or legally asserted. Payment under this indemnification shall be made within 30 days from the date such holder of this Debenture or assignee makes written demand therefor. A certificate as to the amount of such Taxes or Other Taxes submitted to Borrower by such holder of this Debenture or assignee shall be conclusive evidence of the amount due from Borrower to such party. Within 30 days after the date of any payment of Taxes, Borrower will furnish to each holder of this Debenture the original or a certified copy of a receipt evidencing payment thereof.
