insurance shall only be subject to alteration or cancellation only after
thirty (30) days' written notice to Secured Party; and that Debtor will deliver
to Secured Party a certificate or memorandum of such insurance within forty-five
(45) days of the date hereof and renewals of such policy or policies at least
forty-five (45) days prior to expiration dates thereof, the said renewals or
policies to be marked "paid" by the issuing company or agent;

             (i)   If the Debtor fails to keep the Collateral insured as above
specified, then the Secured Party, may, at Secured Party's option, insure the
same for its insurable value, including replacement value, and the cost of such
insurance to Secured Party shall become a debt owing to Secured Party by Debtor
and secured hereby.

             (ii)  No loss or damage to the Collateral shall otherwise affect
the Debtor's obligations hereunder.

             (iii) Except as otherwise provided in the Loan Agreement, all

under this Security Agreement and the Security Interest shall attach thereto.

Interest hereby granted, Debtor has full and fee simple title to the Collateral
free from any and all liens, encumbrances, charges or claims of any nature or
kind whatsoever. To its actual knowledge, Debtor has not done or suffered
anything to prejudice, frustrate or destroy the Security Interest and Debtor
will defend the Collateral and every part thereof unto the Secured Party, its
successors and assigns, against any and all claims and demands of all persons
claiming the same or any interest therein, at any time.

         (i) Financing Statements. To Debtor's actual knowledge, except for the
financing statements of even date herewith filed on behalf of the Secured Party,

or affecting the Collateral or any part thereof or any proceeds thereof is on

         (j) Sale, Lease or Disposition of Collateral. Except as otherwise is
specifically provided in the Loan Agreement, the Debtor, will not, without
written consent of the Secured Party sell, contract to sell, lease encumber or

permit it to become an accession to other goods except in the ordinary course of
business, until this Security Agreement and all debts secured thereby have been
fully satisfied.

         (k) Taxes and Assessments. Debtor shall promptly pay when due all
taxes, license fees, assessments, claims, and other charges ("Taxes") levied or
assessed against or on the Collateral or on its use and operation, except when
and to the extent Debtor is contesting such items in good faith. If the Taxes
remain unpaid at the date fixed for the payment thereof, or if any lien shall be
claimed thereunder which in Secured Party's opinion may create a valid
obligation having priority over the rights

                                       3
<PAGE>

granted to Secured Party herein and if Debtor is not diligently contesting such
items in good faith, Secured Party may, without notice to Debtor, on Debtor's
behalf, pay such Taxes, and the amount thereof shall be an obligation secured
hereby and due to Secured Party on demand. Debtor further agrees to pay any and
all fees, costs, and expenses of whatever kind and nature (including any taxes,
reasonable attorney's fees, or costs for insurance of any kind) which Secured
Party may incur in filing public notices, preparing or filing documents, making
title examinations or rendering opinions, protecting, maintaining, or preserving
the Collateral, foreclosing the Security Interest granted hereunder, whether
through judicial proceedings or otherwise, or in defending or prosecuting any
actions or proceedings arising out of or related to the Secured Party's
transactions with Debtor under this Agreement.

franchise taxes and corporation taxes, sales taxes, payroll taxes, income taxes,
permit fees, imposts, duties and charges, levied, assessed or imposed upon it,

kind or description, except when and to the extent Debtor is contesting such
items in good faith.

all covenants and agreements set forth in this Security Agreement and in the
Loan Agreement.

or other forms of identification in the form required by Secured Party of any or
all Collateral, together with such other evidence of the existence and identity
of such collateral as Secured Party may reasonably require.

      5. Rights Upon Default. Upon the occurrence and during the continuance of
an Event of Default described in Paragraph 7 hereof, Secured Party may then, or
any time thereafter (such default not having previously been cured), declare the
whole of the indebtedness hereby secured with interest thereon, to be due and
payable according to the terms of the Note, and shall then have all the remedies
of a secured party under the laws of the State of Alabama, including without
limitation, the following:

<PAGE>

         (c) Notice. Written notice, when required by law, sent to the Debtor's
address shown herein at least fifteen (15) calendar days (counting the day of
sending) before the date of a proposed disposition of the Collateral is

         (d) Reimbursement. Debtor shall reimburse Secured Party for any expense
reasonably incurred by Secured Party in protecting or enforcing Secured Party's
rights under this Security Agreement, including without limitation reasonable
attorney's fees and legal expense and all reasonable expenses of insuring,
taking possession, holding, preparing for disposition, and disposing of the
Collateral. After deduction of such expenses, Secured Party may apply the
proceeds of disposition to the indebtedness specifically secured hereby, in such
order and amounts as Secured Party elects.

         (e) Exemptions. The Debtor waives to the extent allowed by law all
personal property rights of exemption allowed Debtor under the Constitution and
laws of Alabama or any other jurisdiction, in connection with or related to the
collection of the indebtedness created herein, whether by garnishment, levy,
attachment or any other process of law. The Debtor agrees to pay all reasonable
costs of collection and foreclosure hereof, including a reasonable attorney's
fee, in the event said indebtedness is not paid to maturity, or other Event of
Default occurs hereunder.

         (f) Judicial Foreclosure. To foreclose the Security Interest created
herein by any available judicial procedure.

         (g) Right of Disposition. To sell, lease, or otherwise dispose of all
or any part of the Collateral, whether in its then condition or after further
preparation or processing, either at public or private sale, or through any
broker, in lots or in bulk, for cash or for credit, with or without warranties
or representations, and upon such other commercially reasonable terms and
conditions as Secured Party in its reasonable discretion may deem advisable, and
Secured Party shall have the right to purchase all or any part of the Collateral
at any such sale.

         (h) Stored Property. Debtor authorizes and licenses Secured Party to
take custody of and store for Debtor's account any personal property placed on,
or in, or attached to any item of Collateral repossessed or taken under process
hereunder. All such personal property that does not constitute Collateral shall
be returned to Debtor on demand. No such repossession, taking, or storing shall
be deemed a conversion or otherwise deemed to be a wrongful act.

         (i) Completion of Work in Process. If any Collateral shall require
maintenance, preparation, or is in process or other unfinished state, Secured
Party shall have the right, at Secured Party's option, to do such maintenance,
preparation, processing, or completion for the purpose of putting the Collateral
in such salable form as it shall deem reasonably appropriate at Debtor's
expense.

         (j) Deficiency and Surplus. Debtor shall be liable to Secured Party

agrees to remit to Debtor, or Debtor's successors or assigns, within a
reasonable time, any surplus resulting therefrom.

         (k) Nonexclusive. No remedy of Secured Party hereunder shall be
exclusive of any other remedy herein or by law provided, but each shall be
cumulative and in addition to every other remedy.

are payable under the Note, Debtor agrees, in addition to any other agreement or
covenants in the Loan Agreement, to do the following:

purpose of preserving, protecting, confirming or otherwise evidencing the
security interest granted hereby for filing in such offices as are deemed by
Secured Party to be necessary or desirable. Debtor shall pay all costs of
recording and filing of financing statements.

         (b) Information Relative to Collateral. Debtor shall furnish to Secured
Party such information relative to the Collateral as Secured Party shall from
time to time reasonably request. Debtor's failure, however, to promptly give
Secured Party such statements shall not affect, diminish, modify, or otherwise
limit Secured Party's Security Interest in the Collateral.

         (c) Inspection of Books. Secured Party, at its own expense, shall have
the right, upon reasonable notice, to inspect, during normal business hours, the
Collateral and books, records or other writings relative thereto. Debtor agrees

Debtor shall, in good faith and with reasonable diligence, continue to prosecute
such cure) after written notice from Secured Party to Debtor.

      8. No Election of Remedies. To the extent that Debtor's obligations are
now or hereafter secured by any assets or property other than the Collateral, or

Party shall have the right in its sole and absolute discretion to determine
which rights, security, liens, security interests, or remedies it shall at any
time pursue, foreclose upon, relinquish, subordinate, modify, or take any other
action with respect to, without in any way modifying or affecting any of them,
or waiving any of Secured Party's rights hereunder.

      9. Waiver. No failure on the part of Secured Party to exercise, and no
delay in exercising any of its rights or remedies hereunder shall operate as a
waiver thereof, nor shall any single or partial exercise by Secured Party of any
right or remedy hereunder preclude any other or future exercise thereof or the
exercise of any other right or remedy permitted hereunder or under the Alabama
Code, or other law.

      10. Amendment. This Security Agreement may not be changed or terminated

      SECTION 5.1 RELATIONSHIP OF BORROWER AND LENDERS. The relationship between
Borrower and Lenders is solely that of debtor and creditor, and Lenders have no
fiduciary or other special relationship with Borrower, and no term or condition

owners of Borrower are experienced in the ownership and operation of properties
similar to the Property, and Borrower and Lenders are relying solely upon such

loss or other financial statement, survey, appraisal, or insurance policy,

accepting the Notes, the Loan Agreement, this Security Document and the other
Loan Documents, Lenders are expressly and primarily relying on the truth and
accuracy of the warranties and representations set forth in Section 2.1 of the
Loan Agreement and Article 3 hereof without any obligation to investigate the

Security Document which imposes on Lenders a tax, either directly or indirectly,
on the Loans or Lenders' interest in the Property, Borrower will pay the tax,
with interest and penalties thereon, if any. If Lenders are advised by counsel
chosen by them that the payment of tax by Borrower would be unlawful or taxable
to Lenders or unenforceable or provide the basis for a defense of usury, then
Lenders shall have the option, exercisable by written notice of not less than
ninety (90) days to declare the Loans immediately due and payable.

      (b) Borrower will not claim or demand or be entitled to any credit or
credits on account of the Loans for any part of the taxes or other charges
assessed against the Property, or any part thereof, and no deduction shall
otherwise be made or claimed from the assessed value of the Property, or any
part thereof; for real estate tax purposes by reason of this Security Document
or the Loans. If such claim, credit or deduction shall be required by law,
Lenders shall have the option, exercisable by written notice of not less than
ninety (90) days, to declare the Loans immediately due and payable.
