           Debtor has good and marketable title to Collateral, except for minor
imperfections in title of non-material amounts and except as otherwise disclosed
to Bank by Debtor in writing, and will warrant and defend same against all
materially adverse claims.  Debtor will not transfer, sell, or lease Collateral
(except in the ordinary course of business which shall include the sale or lease
of obsolete equipment and the exchange of equipment and inventory).  Debtor
agrees to pay promptly all taxes and assessments upon or for the use of
Collateral and on this Security Agreement. At its option, and upon prior written
notice to Borrower, Bank may discharge taxes, liens, security interests or other
encumbrances at any time levied or placed on Collateral, except to the extent
Borrower notifies Bank that it is in good faith contesting any such encumbrance

part of the Collateral. In the event of a default which is not timely cured,
Debtor waives any and all rights to notice or to hearing prior to Bank's taking
immediate possession or control of any Collateral, and to any bond or security

in the normal course of business, vehicles or other assets or items of
Collateral which are not customarily fixed at or in a single location.  Debtor

                    7. COLLATERAL CONDITION AND LAWFUL USE.
                       ------------------------------------

           Debtor represents that Collateral is in good repair and condition and
that Debtor shall use reasonable care to prevent Collateral from being
materially damaged or depreciating, except as allowed by ordinary wear and tear.
Debtor shall immediately notify Bank of any material loss or damage to
Collateral.  Debtor shall not permit any item of  Collateral to become a fixture
to real estate or an accession to other personal property, except as required in
the ordinary course of Debtor's business.  Debtor represents it is in compliance
in all material respects with all federal, state local laws, and, where
applicable, laws and regulations of any foreign jurisdiction, and rules and
regulations applicable to its properties, Collateral, operations, business, and
finances, including, without limitation, any federal or state laws relating to
liquor (including 18 U.S.C. (S) 3617, et seq.) or narcotics (including 21 U.S.C.
                                      -------    
(S) 801, et seq.) and all applicable federal, state, local laws,  and, where
         -------
applicable, laws and regulations of any foreign jurisdiction and regulations
intended to protect the environment.

                         8. RISK OF LOSS AND INSURANCE.
                            ---------------------------

           Debtor shall bear all risk of loss with respect to the Collateral.
The injury to or loss of Collateral, either partial or total, shall not release
Debtor from payment or other performance hereof.  Debtor agrees to obtain and
keep in force casualty and hazard insurance on Collateral naming Bank as loss
payee.  Such insurance is to be in form and amounts satisfactory to Bank.  All
such policies shall provide to Bank a minimum of thirty (30) days written notice
of cancellation.  Debtor shall furnish to Bank such policies, or other evidence
of such policies satisfactory to Bank.  Bank is authorized, but not obligated,
to purchase any or all insurance or "Single Interest Insurance" protecting such
interest as Bank deems appropriate against such risks and for such coverage and
for such amounts, including either the loan amount or value of the Collateral at
its discretion, all at Debtor's expense.  In such event, Debtor agrees to
reimburse Bank for the cost of such insurance and Bank may add such cost to the
Obligations.  Debtor shall bear the risk of loss to the extent of any deficiency
in the effective insurance coverage with respect to loss or damage to any of the
Collateral.  Debtor hereby assigns to Bank the proceeds of all such insurance
and directs any insurer to make payments directly to Bank.  Debtor hereby
appoints Bank its attorney-in-fact, which appointment shall be irrevocable and
coupled with an interest for so long as the Obligations are unpaid, to file
proof of loss and/or any other forms required to collect from any insurer any
amount due from any damage or destruction of Collateral, to agree to and bind
Debtor as to the amount of said recovery, to designate payee(s) of such
recovery, to grant releases to insurer, to grant subrogation rights to any
insurer, and to endorse any settlement check or draft.  Debtor agrees not to
exercise any of the foregoing powers granted to Bank without the Bank's prior
written consent, which consent shall not be unreasonably withheld.

                            9. FINANCING STATEMENTS.
                               ---------------------

          No Financing Statement (other than any filed by Bank or disclosed as a
Permitted Lien ) covering any of Collateral or proceeds thereof is on file in
any public filing office.  This Security Agreement, or a copy thereof, or any
Financing Statement executed hereunder may be recorded.  On request of Bank,
Debtor will execute one or more Financing Statements in form satisfactory to
Bank and will pay all costs and expenses of filing the same or of filing this
Security Agreement in all public filing offices, where filing is deemed by Bank
to be desirable.  Bank is authorized to file Financing Statements relating to
Collateral without Debtor's signature where authorized by law.  Debtor appoints
Bank as its attorney-in-fact to execute such documents necessary to accomplish
perfection of Bank's security interest.  The appointment is coupled with an
interest and shall be irrevocable as long as any Obligations remain outstanding.
Debtor further agrees to take such other actions as might be requested for the
perfection, continuation and assignment, in whole or in part, 

                                     Page 3

of the security interests granted herein. If certificates are issued or
outstanding as to any of the Collateral, Debtor will cause the security
interests of Bank to be properly protected, including perfection of notation
thereon.

is (a) genuine and enforceable in accordance with its terms except as limited by
law; (b) not subject to any defense, set-off, claim or counterclaim of a
material nature against Debtor except as to which Debtor has notified Bank in
writing; and (c) not subject to any other circumstances that would materially
impair the validity, enforceability or amount of such Collateral except as to
which Debtor has notified Bank in writing.  Except in the ordinary course of
business, Debtor shall not amend, modify or supplement any lease, contract or
agreement contained in the Collateral or waive any provision therein, without
prior written consent of Bank.

                            14. ACCOUNT INFORMATION.
                                --------------------

           From time to time, at the Bank's reasonable request, Debtor shall
provide Bank with schedules describing all accounts and contracts, including
customers' addresses, credited or acquired by Debtor and at the Bank's request
shall execute and deliver written assignments of contracts and other documents
evidencing such accounts and contracts to Bank.  Together with each schedule,
Debtor shall, if requested by Bank, furnish Bank with copies of Debtor's sales
journals, invoices, customer purchase orders or the equivalent, and original
shipping or delivery receipts for all goods sold, and Debtor warrants the
genuineness thereof.   Bank shall hold all such information in confidence and

or federal law or regulation and upon order of court.

                       15. ACCOUNT AND CONTRACT DEBTORS.
                           -----------------------------

           In the event of a default which is not timely cured, Bank shall have
the right to notify the account and contract debtors obligated on any or all of
the Collateral to make payment thereof directly to Bank and Bank may take
control of all proceeds of any such Collateral, which rights Bank may exercise
at any time.  The cost of such collection and enforcement, including attorneys'
fees 

                                     Page 4
<PAGE>
 
and expenses, shall be borne solely by Debtor whether the same is incurred
by Bank or Debtor.  Upon demand of Bank, Debtor will, upon receipt of all
checks, drafts, cash and other remittances in payment on Collateral, deposit the
same in a special bank account maintained with Bank, over which Bank also has
the power of withdrawal.

           If a Default occurs, no discount, credit, or allowance shall be
granted by Debtor to any account or contract debtor and no return of merchandise
shall be accepted by Debtor without Bank's consent, except as provided by
contract with Debtor's customers or in the Debtor's ordinary course of business.
Bank may, after Default, settle or adjust disputes and claims directly with
account and contract debtors for amounts and upon terms that Bank considers
advisable, and in such cases, Bank will credit the Obligations with the net
amounts received by Bank, after deducting all of the expenses incurred by Bank.
Debtor agrees to indemnify and defend Bank and hold it harmless with respect to
any claim or proceeding arising out of any matter related to collection of the
Collateral.

organization, Debtor shall immediately notify Bank in writing and execute all
documents and take all actions reasonably demanded by Bank to ensure recognition
by such governmental unit or organization of the rights of Bank in the
Collateral.

                                     ----------

           So long as no Default has occurred, Debtor shall have the right in
the regular course of business, to process and sell Debtor's inventory. In the
event of a default which is not timely cured and upon demand of Bank, Debtor
will, upon receipt of all checks, drafts, cash and other remittances, in payment
of Collateral sold, deposit the same in a special bank account maintained with
Bank, over which Bank also has the power of withdrawal. Debtor shall be in

respects. Without limiting the generality of the previous sentence, Debtor shall
materially comply with all requirements of the federal Fair Labor Standards Act
in the conduct of its business and the production of inventory. Debtor shall
notify Bank immediately of any known violation by Debtor of the Fair Labor
Standards Act, and a failure of Debtor to so notify Bank shall constitute a
continuing representation that all inventory then existing has been produced in
compliance with the Fair Labor Standards Act.

                        18. INSTRUMENTS, CHATTEL PAPER.
                            ---------------------------

properly assigned to, deposited with and held by Bank, unless Bank shall
hereafter otherwise direct or consent in writing.  Bank may, without notice,
before or after maturity of the Obligations, exercise any or all rights of
collection, conversion, or exchange and other similar rights, privileges and
options pertaining to the Collateral, but shall have no duty to do so.

                            19. COLLATERAL DUTIES.

prepaid to Debtor's address as provided herein. The Bank, without any obligation
to do so, shall endeavor to give Notice to the Debtor of Bank's exercise of its

constitute a default hereunder by the Bank, nor shall it impair, prohibit, or
preclude the Bank from enforcing any or all of its right under the Loan
Documents.

           (f)    Application of Proceeds. Bank shall be entitled to apply the

Loan Documents shall be valid unless in writing and signed by an officer of Bank
and the Borrower. No waiver by Bank of any Default shall operate as a waiver of
any other Default or of the same Default on a future occasion. Neither the
failure of, nor any delay by, Bank in exercising any right, power or privilege
granted pursuant to any Loan Document shall operate as a waiver thereof, nor
shall a single or partial exercise thereof preclude any other or further

shall not assign its rights and interest hereunder without the prior written
consent of Bank, and any attempt by Debtor to assign without Bank's prior

                  -------------

                  -------------

                                    ------------

           Upon demand of any party hereto, whether made before or after
institution of any judicial proceeding, any dispute, claim or controversy
arising out of, connected with or relating to this Security Agreement and the
other Loan Documents ("Disputes") between or among parties to this Security
Agreement shall be resolved by binding arbitration as provided herein.
Institution of a judicial proceeding by a party does not waive the right of that
party to demand arbitration hereunder. Disputes may include, without limitation,
tort claims, counterclaims, disputes as to whether a matter is subject to
arbitration, claims brought as class actions, claims arising from Loan Documents
executed in the future, or claims arising out of or connected with the
transaction reflected by this Security Agreement.

           Arbitration shall be conducted under and governed by the Commercial
Financial Disputes Arbitration Rules (the "Arbitration Rules") of the American
Arbitration Association (the "AAA") and Title 9 of the U.S. Code. All
arbitration hearings shall be conducted in the city in which the office of Bank
first stated above is located. The expedited procedures set forth in Rule 51 et
                                                                             --
seq. of the Arbitration Rules shall be applicable to claims of less than
---- 
$1,000,000.00. All applicable statutes of limitation shall apply to any Dispute.
A judgment upon the award may be entered in any court having jurisdiction. The
panel from which all arbitrators are selected shall be comprised of licensed
attorneys. The single arbitrator selected for expedited procedure shall be a
retired judge from the highest court of general jurisdiction, state or federal,
of the state where the hearing will be conducted or if such person is not
available to serve, the single arbitrator may be a licensed attorney.
Notwithstanding the foregoing, this arbitration provision does not apply to
disputes under or related to swap agreements.

                  29. PRESERVATION AND LIMITATION OF REMEDIES.
                      ----------------------------------------

           Notwithstanding the preceding binding arbitration provisions, Bank
and Debtor agree to preserve, without diminution, certain remedies that any
party hereto may employ or exercise freely, independently or in connection with
an arbitration proceeding or after an arbitration action is brought. Bank and
Debtor shall have the right to proceed in any court of proper jurisdiction or by
self-help to exercise or prosecute the following remedies, as applicable:

           (a) all rights to foreclose against any real or personal property or
other security by exercising a power of sale granted under Loan Documents or
under applicable law or by judicial foreclosure and sale, including a proceeding
to confirm the sale;

                                    Page 10
<PAGE>
 
           (b) all rights of self-help including peaceful occupation of real
property and collection of rents, set-off, and peaceful possession of personal
property;

           (c) obtaining provisional or ancillary remedies including injunctive
relief, sequestration, garnishment, attachment, appointment of receiver and
filing an involuntary bankruptcy proceeding; and

           (d) when applicable, a judgment by confession of judgment.
Preservation of these remedies does not limit the power of an arbitrator to
grant similar remedies that may be requested by a party in a Dispute.

           Debtor and Bank agree that they shall not have a remedy of punitive
or exemplary damages against the other in any Dispute and hereby waive any right
or claim to punitive or exemplary damages they have now or which may arise in
the future in connection with any Dispute whether the Dispute is resolved by
arbitration or judicially.

                          30. DELIVERY AND ACCEPTANCE.
