REMEDIES. The rights and remedies, privileges, obligations, and duties of Secured Party and Nova Factor with respect to this Security Agreement and the security interest of Secured Party shall be as set forth in the Uniform Commercial Code of the State of Tennessee (the "Code"), and in addition thereto, as set forth herein. Upon the occurrence of any Event of Default, Secured Party shall have the right (a) to declare all of the Secured Obligations to be immediately due and payable, whereupon all such Secured Obligations shall become immediately due and payable without presentment, demand, protest or further notice of any kind, all of which are hereby expressly waived by Nova Factor, anything contained herein to the contrary notwithstanding; and (b) to exercise any one or more of the rights and remedies exercisable by a secured party under the Code (subject to any rights of Nova Factor to redeem the Collateral provided therein) or under any other applicable law. Upon the occurrence of any Event of Default, and without limiting the generality of the foregoing, Secured Party shall have the right to sell the Collateral at public or private sale. All reasonable attorneys' fees and disbursements and all other costs, charges, premiums and other expenses incurred in connection with any such sale shall be charged against and deducted from the proceeds thereof, with the balance, if any, applied in reduction of the Secured Obligations of Nova Factor to Secured Party, and in the event there is a deficiency, said deficiency shall be payable forthwith by Nova Factor to Secured Party (except as otherwise provided in Section 3.2 of the Distribution Agreement). Notice of public or private sale, if given, shall be sufficiently given for all purposes if published once in any newspaper of general circulation distributed in the City of Memphis, Tennessee, not less than ten days prior to sale. It is agreed that ten days' written notice of any such sale to Nova Factor or any other person shall be sufficient for all purposes and is commercially reasonable. Secured Party may itself purchase the whole, or any part of the Collateral or any interest therein, free from any right of redemption on the part of Nova Factor, which right of redemption on the part of Nova Factor is hereby waived and released, but only to the extent such waiver and release is permitted by applicable law. Secured Party shall not be liable for failure to collect or demand payment of, or to protest, or give notice of nonpayment of, the Collateral or any part thereof, or for any delay in so doing, nor shall Secured Party be under any obligation to foreclose on or sell any Collateral or to take any other action whatsoever in regard to the Collateral or any part thereof, except that Secured Party hereby agrees to credit against the outstanding aggregate invoice price of all Inventory an amount equal to the outstanding aggregate invoice price of all properly stored Inventory which is returned by Nova Factor to Secured Party in original, sealed packaging and having not less than thirty (30) days remaining shelf life. 5. TRANSFER OF COLLATERAL. Nova Factor shall not sell, lease, transfer, assign, mortgage, pledge or otherwise dispose of all or any portion of the -8- Collateral except in accordance with the Distribution Agreement or when authorized by the Secured Party in writing. 6. RELEASE OF COLLATERAL. Promptly following payment in full or satisfaction of the Secured Obligations, the security interest created hereby shall terminate, and Secured Party shall execute and deliver such documents as are necessary to release Secured Party's security interest in the Collateral, whether such security interest was created hereby or otherwise; it being the intention of the parties hereto that, upon payment in full or satisfaction of the Secured Obligations, Nova Factor shall hold the Collateral free and clear of all liens, claims, charges, security interests, mortgages or encumbrances of Secured Party or any assignee or subrogee of Secured Party. 7. BENEFIT; GOVERNING LAW. This Security Agreement shall benefit and bind the successors, and permitted assigns of the parties hereto, and shall be governed by and construed in accordance with the laws of the State of Tennessee (but not including the choice-of-law rules thereof). 8. WAIVER. No delay or failure on the part of any party hereto in exercising any right, power or privilege under this Security Agreement or under any other instruments given in connection with or pursuant to this Security Agreement shall impair any such right, power or privilege or be construed as a waiver or default or any acquiescence therein. No waiver shall be valid against any party hereto unless make in writing and signed by the party against whom enforcement of such waiver is sought and then only to the extent expressly specified therein. 9. ASSIGNMENT. Nova Factor shall not assign this Security Agreement, in whole or in part, whether by operation of law or otherwise, without the prior written consent of Secured Party. 10. NOTICES.
