            3. Representations and Warranties of Borrower. Borrower represents,
warrants and agrees as follows:

                (a) Except for encumbrances described in the schedules to the
            Loan Agreement, (the "Permitted Encumbrances"), Borrower is the
            owner of the Collateral free and clear of any liens and security
            interests. Borrower will defend the Collateral against the claims
            and demands of all persons other than the holders of the Permitted
            Encumbrances. The Permitted Encumbrances include the senior security
            interest described in that Intercreditor Agreement dated as of the
            date hereof among FINOVA, Argosy and The CIT Group/Business Credit
            Inc.

                                      -2-
<PAGE>

                (b) The address set forth on Schedule 3(b) hereto is Borrower's
            principal place(s) of business and the location of all tangible
            Collateral and the place where the records concerning all intangible
            Collateral are kept and/or maintained.

                (c) 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.

            4. Agreements With Respect to the Collateral. Borrower covenants and
agrees with Lender as follows:

                (a) Borrower will not permit any of the Collateral to be removed
            from the location specified herein, except for temporary periods in
            the normal and customary use thereof, without the prior written
            consent of Lender.

                (b) Borrower shall notify Lender in writing of any change in the
            location of Borrower's principal place of business (or residence) or
            the location of any tangible Collateral or the place(s) where the
            records concerning all intangible Collateral are kept or maintained.

                (c) Borrower will keep the Collateral in good condition and
            repair and will pay and discharge all taxes, levies and other
            impositions levied thereon as well as the cost of repairs to or
            maintenance of same, and will not permit anything to be done that
            may impair the value of any of the Collateral. If Borrower fails to
            pay such sums, Lender may do so for Borrower's account and add the
            amount thereof to the Obligations.

                (d) Until the occurrence of an Event of Default, Borrower shall
            be entitled to possession of the Collateral and to use the same in
            any lawful manner, provided that such use does not cause excessive
            wear and tear to the Collateral, cause it to decline in value at an
            excessive rate, or violate the terms of any policy of insurance
            thereon.

                (e) Borrower will not sell, exchange, lease or otherwise dispose
            of any of the Collateral or any interest therein without the prior
            written consent of Lender. Notwithstanding the foregoing, so long as
            an Event of Default is not continuing, Borrower shall have the right
            to process and sell Borrower's inventory in the regular course of
            business and to sell or otherwise dispose of obsolete assets in the
            ordinary course of business. 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 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 subject to the security interest
            granted hereby.

                (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.

                                      -3-
<PAGE>

                (g) 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 in 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. Any money received by Lender under said
            policies may be applied to the payment of the Obligations, whether
            or not due and payable, or at Lender's option may 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
            Obligations.

                (h) Borrower will not permit any liens or security interests
            other than those created by this Agreement and the Permitted
            Encumbrances 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.

            5. Remedies Upon Default. Upon and during the continuance of an
Event of Default under and as defined in the Loan Agreement, Lender may pursue
any or all of the following remedies, without any notice to Borrower except as
required below:

                (a) [Intentionally Omitted].

                (b) Lender may take possession of any or all of the Collateral.
            Borrower hereby consents to Lender's entry into any of Borrower's
            premises to repossess Collateral, and specifically consents to
            Lender's forcible entry thereto as long as Lender causes no
            significant damage to the premises in the process of entry (frilling
            of locks, cutting of chains and the like do not in themselves cause
            "significant" damage for the purposes hereof) and provided that
            Lender accomplishes such entry without a breach of the peace.

                (c) Lender may dispose of the Collateral at private or public
            sale. Any required notice of sale shall be deemed commercially
            reasonable if given at least ten (10) days prior to sale. Lender may
            adjourn any public or private sale to a different time or place
            without notice or publication of such adjournment, and may adjourn
            any sale either before or after offers are received. The Collateral
            may be sold in such lots as Lender may elect, in its sole
            discretion. Lender may take such action as it may deem necessary to
            repair, protect, or maintain the Collateral pending its disposition.

                (d) Lender may recover any or all proceeds of accounts from any
            bank or other custodian who may have possession thereof. Borrower
            hereby authorizes and directs all custodians of Borrower's assets to
            comply with any demand for payment made by Lender pursuant to this
            Agreement, without the need of confirmation from Borrower

                                      -4-
<PAGE>

            and without making any inquiry as to the existence of an Event of
            Default or any other matter. Lender may engage a collection agent to
            collect accounts for a reasonable percentage commission or for any
            other reasonable compensation arrangement.

                (e) Lender may notify any or all account debtors that subsequent
            payments must be made directly to Lender or its designated agent.
            Such notice may be made over Lender's signature or over Borrower's
            name with no signature or both, in Lender's discretion. Borrower
            hereby authorizes and directs all existing or future account debtors
            to comply with any such notice given by Lender, without the need of
            confirmation from Borrower and without making any inquiry as to the
            existence of an Event of Default or as to any other matter.

                (f) Lender may, but shall not be obligated to, take such
            measures as Lender may deem necessary in order to collect any or all
            of the accounts. Without limiting the foregoing, Lender may
            institute any administrative or judicial action that it may deem
            necessary in the course of collecting and enforcing any or all of
            the accounts. Any administrative or judicial action or other action
            taken by Lender in the course of collecting the accounts may be
            taken by Lender in its own name or in Borrower's name. Lender may
            compromise any disputed claims and may otherwise enter into
            settlements with account debtors or obligors under the accounts,
            which compromises or settlements shall be binding upon Borrower.
            Lender shall have no duty to pursue collection of any account, and
            may abandon efforts to collect any account after such efforts are
            initiated.

                (g) Lender may, with respect to any account involving
            uncompleted performance by Borrower, and with respect to any general
            intangible or other Collateral whose value may be preserved by
            additional performance on Borrower's part, take such action as
            Lender may deem appropriate including, but not limited, to
            performing or causing the performance of any obligation of Borrower
            thereunder, the making of payments to prevent defaults thereunder,
            and the granting of adequate assurances to other parties thereto
            with respect to future performance. Lender's action with respect to
            any such accounts or general intangibles shall not render Lender
            liable for further performance thereunder unless Lender so agrees in
            writing.

                (h) Lender may exercise its lien upon and right of setoff
            against any monies, items, credits, deposits or instruments that
            Lender may have in its possession and that belong to Borrower or to
            any other person or entity liable for the payment of any or all of
            the Obligations.

                (i) Lender may exercise any right that it may have under any
            other document evidencing or securing the Obligations or otherwise
            available to Lender at law or equity.

            6. Audits and Examinations. Lender shall have the right, at any
reasonable time and, in the absence of an Event of Default, upon reasonable
advance notice, by its own auditors, accountants or other agents, to examine or
audit any of the books and records of Borrower, or the Collateral, all of which
will be made available upon request. Such accountants or other representatives
of Lender will be permitted to make any verification of the existence of the
Collateral or accuracy of the records that Lender deems necessary or proper. Any
reasonable

                                      -5-
<PAGE>

expenses incurred by Lender in making such examination, inspection, verification
or audit shall be paid by Borrower promptly on demand and shall constitute part
of the Obligations.

            7. Termination Statement. Upon receipt of proper written demand
following the payment in full of the Obligations and termination of any
commitment of Lender to make any future advances to Borrower, Lender at its
option, shall send a termination statement with respect to any financing
statement filed to perfect Lender's security interests in any of the Collateral
to Borrower or cause such termination statement to be filed with the appropriate
filing officer(s).

            8. Power of Attorney. Borrower hereby constitutes 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 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 Lender may
designate; to execute any of the documents referred to in Section 3(c) hereof in
order to perfect and/or maintain the security interests and liens granted herein
by Borrower to Lender; to do all other acts and things necessary to carry out
the purposes of and remedies provided under this Agreement. All acts of said
attorney or designee are hereby ratified and approved, and said attorney or
designee shall not be liable for any acts of commission or omission (other than
acts of gross negligence or willful misconduct), nor for any error of judgment
or mistake of fact or law. This power being coupled with an interest is
irrevocable until all of the Obligations are paid in full and any and all
promissory notes executed in connection therewith are terminated and satisfied.

            9. Binding Effect. This Agreement shall inure to the benefit of
Lender's successors and assigns and shall bind Borrower's heirs,
representatives, successors and assigns.

            10. 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.

            11. Governing Law and Amendments. This Agreement shall be construed
and enforced under the laws of the State of Tennessee applicable to contracts to
be wholly performed in such State. No amendment or modification hereof shall be
effective except in a writing executed by each of the parties hereto.

            12. Survival of Representations and Warranties. All representations
and warranties contained herein or made by or furnished on behalf of Borrower in
connection herewith shall survive the execution and delivery of this Agreement.

            13. Counterparts. This Agreement maybe executed in any number of
counterparts and by different parties to this Agreement in separate
counterparts, each of which when so executed shall be deemed to be an original
and all of which taken together shall constitute one and the same Agreement.

                                      -6-

            14. Construction and Interpretation. Should any provision of this
Agreement require judicial interpretation, the parties hereto agree that the
court interpreting or construing the same shall not apply a presumption that the
terms hereof shall be more strictly construed against one party by reason of the
rule of construction that a document is to be more strictly construed against
the party that itself or through its agent prepared the same, it being agreed
that Borrower, Lender and their respective agents have participated in the
preparation hereof.

            15. Consent to Jurisdiction, Exclusive Venue. Borrower hereby
irrevocably consents to the Jurisdiction of the United States District Court for
the Middle District of Tennessee and of all Tennessee state courts sitting in
Davidson County, Tennessee, for the purpose of any litigation to which Lender
may be a party and which concerns this Agreement or the Obligations. It is
further agreed that venue for any such action shall lie exclusively with courts
sitting in Davidson County, Tennessee, unless Lender agrees to the contrary in
writing.

            16. Waiver of Trial by Jury. LENDER AND BORROWER HEREBY KNOWINGLY
AND VOLUNTARILY WITH THE BENEFIT OF COUNSEL WAIVE TRIAL BY JURY IN ANY ACTIONS,
PROCEEDINGS, CLAIMS OR COUNTER-CLAIMS, WHETHER IN CONTRACT OR TORT OR OTHERWISE,
AT LAW OR IN EQUITY, ARISING OUT OF OR IN ANY WAY RELATING TO THIS AGREEMENT OR
THE LOAN DOCUMENTS.
