       1. Covenants. 1.1 The Mortgaged Property shall remain specially
mortgaged, pledged, affected and hypothecated to, and subject to a security
interest in favor of, Mortgagee until the full and final payment, observance
and performance of the Obligations and cancellation of this Mortgage from the
public records. Mortgagor shall not sell, transfer, mortgage, assign, pledge,
alienate or create any security interest in the Mortgaged Property. In no event
shall any such act by Mortgagor, whether or not authorized by Mortgagee,
prejudice the rights of Mortgagee under this mortgage.

       1.2. Mortgagor shall make all repairs, additions, and improvements
necessary to maintain the Mortgaged Property in good condition and to prevent
any impairment of the security of this mortgage. If Mortgagor fails to maintain
the Mortgaged Property in good condition, Mortgagee may, at its option, cause
the Mortgaged Property to be maintained in good condition at Mortgagor's cost.

       1.3. (a) Mortgagor shall keep the Mortgaged Property constantly insured
against risk of loss by fire, wind, storm, flood, tornado, theft, and all such
other hazards, casualties, and contingencies as may be deemed necessary by
Mortgagee. The insurance shall be in such amounts and shall be issued by such
companies as are acceptable to Mortgagee. All policies of insurance shall be
delivered to Mortgagee, shall contain a loss payable clause in favor of
Mortgagee, and shall be in a form acceptable to Mortgagee. All renewal policies
shall be delivered to Mortgagee at least fifteen (15) days prior to the
expiration date of the existing policy.

              (b) The insurance policies required by this mortgage shall
provide that any loss payable to Mortgagee and Mortgagor, as their respective
interests may appear, shall be payable to Mortgagee notwithstanding any act or
omission of Mortgagor or of any other party, which would otherwise result in a
forfeiture of such insurance, and that policies shall not be canceled even for
nonpayment of premium or the coverage reduced without at least thirty (30) days
prior written notice to Mortgagee.

              (c) Mortgagor shall promptly notify Mortgagee of any insured
loss. If Mortgagee receives any sum of money from any insurance policy
affecting the Mortgaged Property, Mortgagee may, at its option and in such
manner


                                       2

   3




as it may determine, (i) retain the money and apply it toward the payment,
observance and performance of any one or more of the Obligations, with
Mortgagee having the right to impute the money among the Obligations in any
manner specified by Mortgagee, or (ii) pay all or part of the money, under such
conditions as Mortgagee may determine, to Mortgagor to enable Mortgagor to
repair or restore the Mortgaged Property or use the money for any other purpose
satisfactory to Mortgagee, all without prejudice to, and without affecting the
lien of, this mortgage.

       1.4. Mortgagor shall pay promptly when due all taxes, local and special
assessments, and governmental and utility charges (collectively, the "Taxes")
imposed, assessed, or levied on all or any part of the Mortgaged Property, and
Mortgagor shall furnish Mortgagee evidence of the payment of the Taxes. If
Mortgagor for any reason does not pay promptly when due any of the Taxes,
Mortgagee is hereby authorized to pay such unpaid Taxes with full subrogation
to all rights of all authorities imposing such Taxes by reason of Mortgagee's
payment, and Mortgagor shall promptly reimburse Mortgagee on demand for Taxes
paid by Mortgagee. Mortgagor shall, if requested by Mortgagee, pay to Mortgagee
an amount equal to the estimated annual Taxes and the premiums for the
insurance required by this Mortgage, so that Mortgagee shall have sufficient
funds available to pay such Taxes and insurance premiums, and Mortgagor shall,
at the option of Mortgagee, pay such amounts either thirty (30) days before
they become due, or in equal monthly payments in advance, with such payments
commencing one (1) month after the date of this mortgage.

       1.5. Mortgagor shall pay promptly when due all of Mortgagor's
obligations that might, if unpaid, result in or permit the creation of a lien
or encumbrance on all or any part of the Mortgaged Property. Mortgagor shall do
everything necessary to preserve the priority of this mortgage without any
expense to Mortgagee. Mortgagor shall notify Mortgagee immediately if any lien
is filed against any part of the Mortgaged Property or if any part of the
Mortgaged Property is seized, attached, or levied against. Mortgagor shall
immediately obtain the release of the Mortgaged Property from any seizure,
lien, or attachment, and if Mortgagor fails to do so, Mortgagee may, at its
option, obtain the release of the Mortgaged Property at Mortgagor's expense.

       1.6. (a) Mortgagor shall comply with all laws, ordinances, regulations,
covenants, conditions, and restrictions affecting the Mortgaged Property, its
use, construction, or maintenance, including, without limitation, all
Environmental Laws. As used in this Mortgage, "Environmental Laws" shall mean

warrants that neither Mortgagor, any occupant of the Mortgaged Property, or the

threatened investigation or inquiry by any governmental authority or to any
remedial obligations under any of the Environmental Laws.

              (b) Mortgagor shall forever indemnify, defend and hold harmless

incurred by Mortgagee to enforce the provisions of this paragraph, including,
without limitation, attorneys' fees and litigation expenses. The provisions of
this paragraph shall survive the cancellation of this mortgage and shall remain
in full force and effect beyond the expiration of any applicable statute of
limitations and payment or satisfaction in full of any single claim of

              Bank in the amount of $1,500,000.00, dated April 21, 1998,
              recorded in MOB 2511, folio 295.



                                       3

   4




       Mortgagor represents and warrants to Mortgagee that the obligations
secured by the $1,500,000.00 Mortgage has been fully paid or performed and that
Mortgagor will have the $1,500,000.00 Mortgage cancelled of record by not later
than February 28, 1999.

       1.10. The maximum amount of the Obligations secured by this mortgage and
assignment of leases and rents shall not at any one time exceed One Hundred
Million ($100,000,000.00) Dollars. Mortgagee shall have full subrogation to
Mortgagor's rights to all Leases and Rents.

       1.11 Mortgagor shall administer the Leases, Rents and Incorporeal Rights
in a fiduciary capacity for the benefit of Mortgagee. Although this instrument
creates a present pledge and assignment of and vested security right in the
Leases and Rents, Mortgagor shall be entitled to collect the Rents until the
occurrence of a Default or until Mortgagee sends written notice to Mortgagor at
Mortgagor's address set forth above, whereupon Mortgagee shall have the right
to receive and collect the Rents. All Proceeds shall be paid directly to
Mortgagee. Mortgagor hereby irrevocably appoints Mortgagee its agent and
attorney-in-fact (coupled with an interest), to demand, sue for, collect,
receive, and receipt for the Rents and Proceeds, and to exercise all the rights
and privileges of Mortgagor under any of the Leases or Incorporeal Rights
affecting the Mortgaged Property, including without limitation, the right to
fix or modify the amount of the Rents, to evict any lessee, tenant or occupant
(the "Lessee") from the Mortgaged Property, to relet such property and to do
all such things as Mortgagee may deem necessary. Mortgagor hereby irrevocably
consents that all Lessees of the Mortgaged Property shall be authorized to pay
the Rents directly to Mortgagee without liability for the determination of the
actual existence of any Default, the Lessees being hereby expressly relieved of
any obligation to Mortgagor with respect to Rents paid to Mortgagee. All Rents
and Proceeds collected under this mortgage shall be applied, after payment of
all costs and charges, as a credit against the Obligations. Mortgagee shall
have no legal or contractual responsibility for the condition of the Mortgaged
Property, for any obligation to perform leases affecting the Mortgaged
Property, or for any dangerous or defective condition of the Mortgaged
Property. Mortgagor indemnifies and shall defend the Mortgagee and its agents,
employees, successors, and assigns (the "Indemnified Parties") and to hold them
harmless from any cost, expense, liability, loss, or damage, including, without
limitation, reasonable attorneys' fees, which may or might be incurred by them
by reason of the assignment of and security interest in the Rents, Leases and
Incorporeal Rights. The obligation set forth herein to indemnify, defend, and
hold the Indemnified Parties harmless shall be secured by this mortgage.

       1.12. Mortgagor hereby agrees to pay promptly all charges, costs, and
attorneys' fees incurred in connection with the preparation, execution, and
recordation of this mortgage.

       1.13. If Mortgagor fails to perform any obligation under this mortgage,
then the Mortgagee may, at its option, perform such obligation, and the cost of
such performance shall be reimbursable to Mortgagee upon demand and added to
the amount secured by this mortgage, provided that the maximum amount to be
secured by this mortgage shall not, at any one time, exceed One Hundred Million
($100,000,000.00) Dollars. Authorizations granted to the Mortgagee to pay or
perform obligations on behalf of the Mortgagor, or to enforce or collect
Leases, Rents and Proceeds, are solely for the benefit of Mortgagee, to be
exercised in Mortgagee's sole discretion, and shall be performed at the sole
risk and expense of Mortgagor. Mortgagee shall have no liability to Mortgagor,
or any other party, either directly or by set-off or compensation, for failure
to perform such obligations or to enforce or collect Leases, Rents or Proceeds,
or for performing in a manner that causes damage to the Mortgagor.

       2. Default and Remedies. 2.1. The occurrence of any one or more of the
following events shall constitute a default (a "Default") under this mortgage:

              (a) failure to pay promptly on demand any principal or interest
due on the Note;

              (b) failure to pay promptly on demand any sums advanced by
Mortgagee for the payment of insurance premiums, Taxes, the cost of maintaining
the Mortgaged Property in good repair, or the cost of obtaining the release of
the Mortgaged Property from any seizure, lien, or attachment;

              (c) failure by Mortgagor to observe or perform any of Mortgagor's
covenants, agreements, and obligations under this mortgage;

              (d) the inaccuracy of any warranty made by Mortgagor to Mortgagee
in this mortgage or otherwise; or

              (e) the seizure, attachment or sequestration of any part of the
Mortgaged Property.

       2.2. If a Default occurs, Mortgagee may, at Mortgagee's option, without
notice to Mortgagor, declare the Obligations to be immediately due and payable,
and may immediately exercise all remedies provided under this mortgage or by
law. For purposes of executory process, Mortgagor confesses judgment in favor
of Mortgagee for the full amount of the Obligations. Mortgagee may cause all or
any part of the Mortgaged Property to be seized and sold under executory or
other legal process without appraisement, which is hereby expressly waived, as
an entirety or in parcels, as Mortgagee may determine, to the highest bidder
for cash, or on such terms as are acceptable to Mortgagee.

       2.3. To the extent permitted by law, Mortgagor hereby expressly waives
(a) the benefit of appraisement provided for in Articles 2332, 2336, 2723 and
2724, Louisiana Code of Civil Procedure, and all other laws conferring such
benefits; (b) the demand and three (3) days delay accorded by Articles 2639 and
2721, Louisiana Code of Civil

Louisiana Code of Civil Procedure; (d) the three (3) days delay provided by
Articles 2331 and 2722, Louisiana Code of Civil Procedure; (e) the benefit of
the other provisions of Articles 2331, 2722, and 2723, Louisiana Code of Civil
Procedure; (f) the benefit of the provisions of any other articles of the
Louisiana Code of Civil Procedure not specifically mentioned above; (g) all
rights of division and discussion with respect to any Obligation; and (h) all
homestead and other exemptions relating to the Mortgaged Property.

       2.4. In addition to all of the other rights and remedies of Mortgagee
under this mortgage, if a Default occurs, Mortgagee may, at Mortgagee's option,
without notice to Mortgagor, obtain an environmental site assessment for the
Mortgaged Property prepared by an environmental consulting firm selected by
Mortgagee and an appraisal of the Mortgaged Property prepared by an appraiser
selected by Mortgagee. Mortgagor shall promptly on demand reimburse Mortgagee
for the cost of the assessment and appraisal and the cost thereof shall be
secured by this Mortgage. Mortgagor shall grant and hereby irrevocably grants
to Mortgagee, and any consulting firms and appraisers hired by Mortgagee,
access to the Mortgaged Property for purposes of preparing and obtaining all
assessments and appraisals.

       2.5. Pursuant to Louisiana Revised Statutes 9:5136, et seq., Mortgagor
hereby designates Mortgagee, or any employee, agent, or other person named by
Mortgagee at the time any seizure of the Mortgaged Property is effected by
Mortgagee to serve as a keeper of the Mortgaged Property pending the judicial
sale thereof. The keeper's fees shall be determined by the Court before which
the proceedings are pending, and the payment of such fees shall be secured by
this mortgage.
