LAW GOVERNING AND SEVERABILITY. This Guaranty shall be governed by and construed in accordance with the laws of the State of Georgia without regard to conflict of law provisions thereof and is intended to be performed in accordance with, and only to the extent permitted by, such laws. If any provision of this Guaranty or the application thereof to any person or circumstance, for any reason and to any extent, shall be invalid or unenforceable, neither the remainder of this Guaranty nor the application of such provision to any other persons or circumstances shall be affected thereby, but rather the same shall be enforced to the greatest extent permitted by law. Guarantor hereby submits to personal jurisdiction in said state for the enforcement of this Guaranty and hereby waives any claim or right under the laws of any other 3 <Page> Loan No. 6518403 state or of the United States to object to such jurisdiction. If such litigation is commenced, Guarantor agrees that service of process may be made by serving a copy of the summons and complaint upon Guarantor, through any lawful means, including upon its registered agent within said state, whom Guarantor hereby appoints as its agent for these purposes. Nothing contained herein shall prevent Lender from bringing any action or exercising any rights against Guarantor personally or against any property of Guarantor within any other county, state, or country. The means of obtaining personal jurisdiction and perfecting service of process set forth above are not intended to be exclusive but are in addition to all other means of obtaining personal jurisdiction and perfecting service of process now or hereafter provided by applicable law. 8.

EFFECT OF BANKRUPTCY. This Guaranty shall continue to be effective or reinstated, as the case may be, if at any time payment to Lender of all or any part of the Non-Recourse Carveout Obligations is rescinded or must otherwise be restored or refunded by Lender pursuant to any insolvency, bankruptcy, reorganization, receivership or other debtor relief proceeding involving Borrower. In the event that Lender must rescind or restore any payment received by Lender in satisfaction of the Non-Recourse Carveout Obligations, as set forth herein, any prior release or discharge of the terms of this Guaranty given to Guarantor by Lender shall be without effect and this Guaranty shall remain in full force and effect. 11.

APPLICATION OF FORECLOSURE PROCEEDS. In the event of any foreclosure sales of the mortgaged property and collateral covered by the Loan Documents, the proceeds of such sales shall be applied first to the discharge of that portion of the indebtedness then remaining unpaid as to which Guarantor is not fully personally liable pursuant to this Guaranty, it being the express intention of the parties that the application of the proceeds of such foreclosure sales shall be in such a manner as not to extinguish or reduce Guarantor's personal liability hereunder until all of the indebtedness as to which Guarantor is not personally liable hereunder has been paid in 4 <Page> Loan No. 6518403 full.
