Grantor hereby ratifies all that said attorneys shall lawfully do or cause to be done by virtue hereof. This power of attorney is a power coupled with an interest and shall be irrevocable. (b) Other Powers. Grantor also authorizes sirrom, at any time and from time to time, to execute, in connection with the sale provided for in Section 8 hereof, any endorsements, assignments or other instruments of conveyance or transfer with respect to the Collateral. (c) No Duty on the Part of Lenders. The powers conferred on Sirrom hereunder are solely to protect the interests of Lenders in the Collateral and shall not impose any duty upon Sirrom to exercise any such powers. Sirrom shall be accountable only for amounts that it actually receives as a result of the exercise of such powers, and neither it nor any of its partners, officers, directors, employees or agents shall be responsible to the Grantor for any act or failure to act hereunder, except for their own gross negligence or willful misconduct or failure to comply with mandatory provisions of applicable law. 6. Performance by Lenders of Grantor's Obligations. If Grantor fails to perform or comply with any of its agreements contained herein and Lenders, as provided for by the terms of this Security Agreement, shall themselves perform or comply, or otherwise cause performance or compliance, with such agreement, the expenses of Lenders incurred in connection with such performance or compliance, together with interest thereon at the highest default rate provided in the Loan Documents, shall be payable by the Grantor to Lenders on demand and shall constitute Obligations secured hereby. 7. Proceeds. It is agreed that if an Event of Default shall occur and be continuing (a) all Proceeds received by Grantor consisting of cash, checks and other cash equivalents shall be held by the Grantor in trust for Lenders, segregated from other funds of the Grantor, and shall, forthwith upon receipt by the Grantor, be turned over to Sirrom in the exact form received by Grantor (duly endorsed by Grantor to Sirrom, if required), and (b) any and all such Proceeds received by Sirrom (whether from Grantor or otherwise) shall promptly be applied by Sirrom against, the Obligations (whether matured or unmatured), such application to be in such order as Sirrom shall elect. Any balance of such Proceeds remaining after the Obligations shall have been paid in full shall be paid over to Grantor or to whomsoever may be lawfully entitled to receive the same. 8. Remedies. If an Event of Default shall occur and be continuing, Lenders, may exercise, in addition to all other rights and remedies granted to it in this Security Agreement and in any other instrument or agreement securing, evidencing or relating to the Obligations, all 8 rights and remedies of a secured party under the UCC. Without limiting the generality of the foregoing, Lenders without demand of performance or other demand, presentment, protest, advertisement or notice of any kind (except any notice required by law referred to below) to or upon Grantor or any other person (all and each of which demands, defenses, advertisements and notices are hereby waived), may in such circumstances forthwith collect, receive, appropriate and realize upon the Collateral, or any part thereof, and/or may forthwith sell, lease, assign, give option or options to purchase, or otherwise dispose of and deliver the Collateral or any part thereof (or, contract to do any of the foregoing), in one or more parcels at public or private sale or sales, at any office of either Lender or elsewhere upon such terms and conditions as it may deem advisable and at such prices as it may deem best, for cash or on credit or on future delivery without assumption of any credit risk. Lenders shall have the right upon any such public sale or sales, and, to the extent permitted by law, to purchase the whole or any part of the Collateral so sold, free of any right or equity of redemption in the Grantor, which right or equity is hereby waived or released. Grantor further agrees, at Lenders' request, to assemble the Collateral and make it available to Lenders at places which Lenders shall reasonably select, whether at the Grantor's premises or elsewhere. Lenders shall apply the net proceeds of any such collection, recovery, receipt, appropriation, realization or sale, after deducting all reasonable costs and expenses of every kind incurred therein or incidental to the care or safekeeping of any of the Collateral or in any way relating to the Collateral or the rights of Lenders hereunder, including, without limitation, reasonable attorneys' fees and disbursements, to the payment in whole or in part of the Obligations, in such order as Lenders may elect, and only after such application and after the payment by Lenders of any other amount required by any provision of law, including, without limitation, Section 9-504(l)(c) of the UCC, need Lenders account for the surplus, if any, to the Grantor. To the extent permitted by applicable law, Grantor waives all claims, damages and demands it may acquire against Lenders arising out of the exercise by them of any rights hereunder. If any notice of a proposed sale or other disposition of Collateral shall be required by law, such notice shall be deemed reasonable and proper if given at least 10 days before such sale or other disposition. Grantor shall remain liable for any deficiency if the proceeds of any sale or other disposition of the Collateral are insufficient to pay the Obligations and the fees and disbursements of any attorneys employed by Lenders to collect such deficiency. 9. Limitation on Duties Regarding Preservation of Collateral. Sirroms's sole duty with respect to the custody, safekeeping and physical preservation of the Collateral in its possession, under Section 9-207 of the UCC or otherwise, shall be to deal with it in the same manner as Sirrom would deal with similar property for its own account. Neither Lenders nor any of their partners, directors, officers, employees or agents shall be liable for failure to demand, collect or realize upon all or any part of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of the Grantor or otherwise. 9 10. Powers Coupled with an Interest. All authorizations and agencies herein Contained with respect to the Collateral are irrevocable and powers coupled with an interest. 11. Severability. Any provision of this Security Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. 12. Paragraph Headings. The paragraph headings used in this Security Agreement are for convenience of reference only and are not to affect the construction hereof or be taken into consideration in the interpretation hereof. 13. No Waiver; Cumulative Remedies. Lenders shall not by any act (except by a written instrument pursuant to Section 14 hereof), delay, indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or to have acquiesced in any default or Event of Default or in any breach of any of the terms and conditions hereof. No failure to exercise, nor any delay in exercising, on the part of Lenders, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by Lenders of any right or remedy hereunder on any occasion shall not be construed as a bar to any right or remedy which Lenders would otherwise have on any future occasion. The rights and remedies herein provided are cumulative, may be exercised singly or concurrently and are not exclusive of any rights or remedies provided by law. 14. Waivers and Amendments; Successors and Assigns. None of the terms or provisions of this Security Agreement may be waived, amended, supplemented or otherwise modified except by a written instrument executed by the Grantor and Sirrom, as agent for Lenders, provided that any provision of this Security Agreement may be waived by in a written letter or agreement executed by Sirrom as agent for Lenders or by telex or facsimile transmission from Sirrom as agent for Lenders. This Security Agreement shall be binding upon the successors and assigns of the Grantor and shall inure to the benefit of Lenders and their successors and assigns. 15. Notices.
