Each Grantor represents, warrants and agrees, on its own behalf, as follows: (a) Except as set forth on Schedule 3(a)(i) hereto (the "Permitted Encumbrances"), Grantor is the owner of Grantor's Collateral, free and clear of any liens and security interests and that it will defend Grantor's Collateral against the claims and demands of all persons other than Permitted Encumbrances. All of Grantor's collateral is presently located in the states and counties set forth on Schedule 3(a)(ii). (b) Grantor will promptly notify Lenders, in writing, of any new place or places of business if Grantor's Collateral is used in business, or of any change in it's residence if Grantor's Collateral is not used in business, and regardless of use, of any change in the location of Grantor's Collateral or any records pertaining thereto. (c) Grantor will pay to Lenders 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 any Grantor and any Lender, and will promptly discharge all said liabilities. (d) Grantor will at all times keep Grantor's Collateral insured against all insurable hazards in amounts equal to the full cash value of the Grantor's Collateral. Such insurance shall be in such companies as may be acceptable to Lenders, with provisions satisfactory to Lenders for payment of all losses thereunder to Lenders as their interests may appear. If required by Lenders, Grantor shall deposit the policies with Lenders. So long as there exists no event of default hereunder or under and Loan Document and the proceeds received under any policy are less than $50,000, Lenders shall deliver said proceeds to Grantor for the purpose of repairing or restoring 3 Grantor's Collateral. If there exists an event of default hereunder or under any Loan Document or if the proceeds received under any policy exceed $50,000, at Lenders' option, said proceeds may be applied to the payment of any indebtedness secured hereby, whether or not due and payable, or at Lenders' option may be delivered by Lenders to Grantor for the purpose of repairing or restoring Grantor's Collateral. Grantor assigns to Lenders all right to receive proceeds of insurance not exceeding the amounts secured hereby, directs any insurer to pay all proceeds directly to Lenders as their interests may appear, and appoints each Lender as Grantor's attorney in fact to endorse any draft or check made payable to Grantor in order to collect the benefits of such insurance; provided, however, that so long as no event of default exists hereunder or under any Loan Document, Grantor shall be entitled to settle and compromise all claims under its casualty policies and, if the proceeds of such settlement or compromise are less than $50,000, Lenders shall disburse said proceeds to Grantor upon receipt of satisfactory evidence that the proceeds shall be used to repair or replace Grantors's damaged or destroyed Collateral. If Grantor fails to keep Grantor's Collateral insured as required by Lenders, Lenders shall have the right to obtain such insurance at Grantor's expense and add the cost thereof to the other amounts secured hereby. (e) Grantor will pay all costs of filing of financing, continuation and termination statements with respect to the security interests created hereby, and Lenders are authorized to do all things that they deem reasonably necessary to perfect and continue perfection of the security interests created hereby and to protect the Collateral. (f) The address set forth after Grantor's signature on this Agreement is Grantor's principal place of business and the place where the records concerning all intangible Grantor's Collateral are kept and/or maintained. 4. Default. Grantor shall be in default upon failure to observe or perform any of Grantor's agreements herein contained, or upon the occurrence of a default or Event of Default under the Loan Agreements or any other Loan Document that has not been cured during the applicable grace period, or if any warranty or statement by Grantor herein or furnished in connection herewith is materially false or misleading in any material respect. 5. Remedies Upon Default. Upon default hereunder, all sums secured hereby shall immediately become due and payable at Lenders' option without notice to Grantor, and Lenders 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 Lenders, all of which shall be cumulative. Whenever Grantor is in default hereunder, and upon demand by Lenders, Grantor shall assemble Grantor's Collateral and make it available to Lenders at a place reasonably 4 convenient to Lenders and Grantor. Any notice of sale, lease or other intended disposition of Grantor's Collateral by Lenders sent to Grantor at the address hereinafter set forth, or at such other address of Grantor as may be shown on Lender's records, at least five (5) days prior to such action, shall constitute reasonable notice to Grantor. Lenders 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. 6. Severability. If any provision of this Agreement is held invalid, such invalidity shall not affect the validity or enforceability of the remaining provisions of this Agreement. 7. Binding Effect. This Agreement shall inure to the benefit of Lenders' successors and assigns and shall bind Grantors' heirs, representatives, successors and assigns. If Grantor is composed of more than one person, firm and/or entity, their obligations hereunder shall be joint and several. 8. Financial Reporting. Grantor has no undisclosed or contingent liabilities that are not reflected in the financial statements on file with Lenders at the execution of this Agreement. Lenders shall have the right, at any time, by its own auditors, accountants or other agents, to examine or audit any of the books and records of Grantor, or Grantor's Collateral, all of which will be made available upon request.

Any reasonable expenses incurred by Lenders in making such examination, inspection, verification or audit shall be paid by said Grantor promptly on demand and shall be secured by the security interest granted hereby. 9. Termination Statement. Grantor agrees that, notwithstanding the payment in full of all indebtedness secured hereby and whether or not there is any outstanding obligation of Lenders to make future advances, Lenders shall not be required to send Grantor a termination statement with respect to any financing statement filed to perfect Lenders' security interest(s) in any of Grantor's Collateral, unless and until Grantor shall have made written demand therefor. Upon receipt of proper written demand, Lenders may at their option, in lieu of sending a termination statement to Grantor, cause said termination statement to be filed with the appropriate filing officer(s). 10.

If Grantor fails to pay such sums, Lenders may do so for Grantor's account and add the amount thereof to the other amounts secured hereby. (e) Until default in any of the terms hereof, or the terms of any indebtedness secured hereby, Grantor shall be entitled to possession of Grantor's Collateral and to use the same in any lawful manner, provided that such use does not cause excessive wear and tear to Grantor's Collateral, cause it to decline in value at an excessive rate, or violate the terms of any policy of insurance thereon. (f) Grantor will not allow any material portion of Grantor's Collateral to be attached to real estate in such manner as to become a fixture or a part of any real estate. 12.

(b) By the execution of this Agreement, Lenders 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 Grantor, but if there is a default by Grantor in the payment of any amount due in respect of any indebtedness secured hereby, then Lenders may, at their election, perform some or all of the obligations provided in said contracts to be performed by Grantor, and if Lenders incur any liability or expenses by reason thereof, the same shall be payable by Grantor upon demand and shall also be secured by this Agreement. (c) At any time after Grantor is in default hereunder or under the Loan Agreement, Lenders shall have the right to notify the account debtors obligated on any or all of Grantor's accounts receivable to make payment thereof directly to Lenders, and to take control of all proceeds of any such accounts receivable.
