Representations, Warranties and Agreements of Borrower. Borrower represents, warrants and agrees as follows: (a) Borrower will promptly notify Lender, in writing, of any change in Borrower's place or places of business if the Collateral is used in business, or of any change in Borrower's residence if the Collateral is not used in business, and regardless of use, of any change in the location of the Collateral or any records pertaining thereto. (b) Except as set forth on Schedule 2.1(l) of the Loan Agreement, Borrower is the owner of the Collateral free and clear of any liens, security interests, claims and encumbrances, contingent or otherwise. Borrower will defend the Collateral against the claims and demands of all persons. (c) Borrower will pay to Lender all amounts secured hereby as and when the same shall be due and payable, whether at maturity, by acceleration or otherwise, and will promptly perform all terms of said indebtedness and this or any other security or loan agreement between Borrower and Lender, and will promptly discharge all said liabilities. (d) Borrower will at all times keep the Collateral insured against all insurable hazards in amounts equal to the full cash value of the Collateral. Such insurance shall be obtained from such companies as may be acceptable to Lender, with provisions satisfactory to Lender for payment of all losses thereunder to Lender as its interests may appear. If required by Lender, Borrower shall deposit the policies with Lender. If an Event of Default (as defined in the Loan Agreement) has occurred and is continuing, any money received by Lender under said policies may be applied to the payment of any indebtedness secured hereby, whether or not due and payable, otherwise said money shall be delivered by Lender to Borrower for the purpose of repairing or restoring the Collateral. Borrower assigns to Lender all right to receive proceeds of insurance not exceeding the amounts secured hereby, directs any insurer to pay all proceeds directly to Lender, and appoints Lender Borrower's attorney in fact to endorse any draft or check made payable to Borrower in order to collect the benefits of such insurance. If Borrower fails to keep the Collateral insured as required by Lender, Lender shall have the right to obtain such insurance at Borrower's expense and add the cost thereof to the other amounts secured hereby. 4 (e) Borrower will pay all costs of filing of financing, continuation and termination statements with respect to the security interests created hereby, and Lender is authorized to do all things that it deems necessary to perfect and continue perfection of the security interests created hereby and to protect the Collateral. (f) The address set forth after Borrower's signature on this Agreement is Borrower's principal place of business and the location where the records concerning all intangible Collateral are kept and/or maintained.

Borrower shall be in default upon failure to observe or perform any of Borrower's agreements herein contained, or upon the occurrence of a default or Event of Default under the Loan Agreement or any other Loan Document (as defined in the Loan Agreement) that has not been cured during the applicable grace period, or if any warranty or statement by Borrower set forth herein or furnished in connection herewith is false or misleading. 5. Remedies Upon Default. Upon the occurrence of an Event of Default (as defined in the Loan Agreement), all sums secured hereby shall immediately become due and payable at Lender's option without notice to Borrower, and Lender may proceed to enforce payment of same and to exercise any and all rights and remedies provided by the Uniform Commercial Code (Tennessee) or other applicable law, as well as all other rights and remedies possessed by Lender, all of which shall be cumulative. Whenever Borrower is in default hereunder, and upon demand by Lender, Borrower shall assemble the Collateral and make it available to Lender at a place reasonably convenient to Lender and Borrower. Any notice of sale, lease or other intended disposition of the Collateral by Lender sent to Borrower at the address hereinafter set forth, or at such other address of Borrower as may be shown on Lender's records, at least five (5) days prior to such action, shall constitute reasonable notice to Borrower. Lender may waive any default before or after the same has been declared without impairing its right to declare a subsequent default hereunder, this right being a continuing one. 5 Severability.

Upon receipt of proper written demand, Lender may at its option, in lieu of sending a termination statement to Borrower, cause said termination statement to be filed with the appropriate filing officer(s). 9. Protection of Collateral. Borrower will not permit any liens or security interests other than those created by this Agreement to attach to any of the Collateral, nor permit any of the Collateral to be levied upon under any legal process, nor permit anything to be done that may impair the security intended to be afforded by this Agreement, nor permit any tangible Collateral to become attached to or commingled with other goods without the prior written consent of Lender. 10.

(f) Borrower will not allow the Collateral to be attached to real estate in such manner as to become a fixture or a part of any real estate. 11. Special Agreements With Respect to Intangible and Certain Tangible Collateral.

Lender's security interest hereunder shall attach to all proceeds of all sales or other dispositions of the Collateral. If at any time any such proceeds shall be represented by any instruments, chattel paper or documents of title, then such instruments, chattel paper or documents of title shall be promptly delivered to Lender and shall be subject to the security interest granted hereby. If at any time any of Borrower's inventory is represented by any document of title, such document of title will be delivered promptly to Lender and shall be subject to the security interest granted hereby. (b) By the execution of this Agreement, Lender shall not be obligated to do or perform any of the acts or things provided in any contracts covered hereby that are to be done or performed by Borrower, but if there is a default by Borrower in the payment of any amount due in respect of any indebtedness secured hereby, then Lender may, at its election, perform some or all of the obligations provided in said contracts to be performed by Borrower, and if Lender incurs any liability or expenses by reason thereof, the same shall be payable by Borrower upon demand and shall also be secured by this Agreement. 8 (c) At any time after Borrower is in default hereunder or under the Loan Agreement, Lender shall have the right to notify the account debtors obligated on any or all of Borrower's accounts receivable to make payment thereof directly to Lender, and to take control of all proceeds of any such accounts receivable. Until such time as Lender elects to exercise such right by mailing to Borrower written notice thereof, Borrower is authorized, as agent of the Lender, to collect and enforce said accounts receivable. 12. Refinancing Prior Debt. Borrower acknowledges and agrees that the Loan constitutes a refinancing of the debt of Borrower to Sirrom Investments, Inc. under that certain Loan and Security Agreement dated as of May 29, 1992 (as amended from time to time the "Original Loan Agreement") and that certain Secured Promissory Note in the original principal amount of One Million Dollars ($1,000,000) dated as of May 29, 1992 executed by Borrower in favor of Sirrom Capital, L.P. (as amended from time to time the "Original Note"). Borrower further acknowledges and agrees that the security interest created under the Original Loan Agreement has been assigned to Lender in connection with refinancing of debt evidenced by the Original Note. 13. Power of Attorney. Borrower hereby constitutes the Lender or its designee, as Borrower's attorney-in-fact with power, upon the occurrence and during the continuance of an Event of Default, to endorse Borrower's name upon any notes, acceptances, checks, drafts, money orders, or other evidences of payment or Collateral that may come into either its or the Lender's possession; to sign the name of Borrower on any invoice or bill of lading relating to any of the accounts receivable, drafts against customers, assignments and verifications of accounts receivable and notices to customers; to send verifications of accounts receivable; to notify the Post Office authorities to change the address for delivery of mail addressed to Borrower to such address as the Lender may designate; to execute any of the documents referred to in Section 3(e) hereof in order to perfect and/or maintain the security interests and liens granted herein by Borrower to the Lender; and to do all other acts and things necessary to carry out this Security Agreement.
