or interference with the use and enjoyment of the Trust Premises or any part

         SECTION 1.7. Security Interests, etc. The Trustor will not directly or
indirectly create or permit or suffer to be created or to remain, and will

(a) in the case of an unpaid Imposition, lien, encumbrance or charge, such
proceedings shall suspend the collection thereof from the Trustor, the Trustee,
the Beneficiary, and the Trust Premises (including any rent or other income
therefrom) and shall not materially interfere with the payment of any such rent
or income, (b) neither the Trust Premises nor any rent or other income therefrom
nor any part thereof or interest therein would be in any material danger of
being sold, forfeited, lost, impaired or interfered with, (c) in the case of a
Legal Requirement, neither the Trustor, the Trustee nor the Beneficiary would be
in material danger of any civil or criminal liability for failure to comply
therewith, (d) the Trustor shall have furnished such security, if any, as may be
required in the proceedings or as may be reasonably requested by the
Beneficiary, (e) the non-payment of the whole or any part of any Imposition will
not result in the delivery of a tax deed to the Trust Premises or any part
thereof because of such non-payment, (f) the payment of any sums required to be
paid with respect to any of the Current Asset Notes or under this Deed of Trust
(other than any unpaid Imposition, lien, encumbrance or charge at the time being
contested in accordance with this Section 1.8) shall not be interfered with or
otherwise affected, (g) in the case of any Insurance Requirement, the failure of
the Trustor to comply therewith shall not affect the validity of any insurance
required to be maintained by the Trustor under Section 2.1, and (h) that
adequate reserves, determined in accordance with GAAP, shall have been set aside
on the Trustor's books.

         SECTION 1.9. Leases. The Trustor represents and warrants to the Trustee
and the Beneficiary that, as of the date hereof, there are no written or oral
leases or other agreements of any kind or nature relating to the occupancy of
any portion of the Property by any Person other than the Trustor other than the
Permitted Encumbrances. Except as permitted by the Credit Agreement, the Trustor
will not enter into any such written or oral lease or other agreement with
respect to any portion of the Property without first obtaining the written
consent of the Beneficiary.

         SECTION 1.10. Compliance with Instruments. The Trustor at its expense
will promptly comply in all material respects with all rights of way or use,
privileges, franchises, servitudes, licenses, easements, tenements,
hereditaments and appurtenances forming a part of the Property and all
instruments creating or evidencing the same, in each case, to the extent
compliance therewith is required of the Trustor under the terms thereof. Except
as is permitted by the Credit Agreement, the Trustor will not take any action
which may result in a forfeiture or termination of the rights afforded to the
Trustor under any such instruments and will not, without the prior written
consent of the Beneficiary, amend any of such instruments in any manner adverse
to the Current Assets Lenders in any material respect.

         SECTION 1.11. Maintenance and Repair, etc. Subject to the provisions of
Section 1.12, the Trustor will keep or cause to be kept all presently and
subsequently erected or acquired Improvements and the sidewalks, curbs, vaults
and vault space, if any, located on or adjoining the same, and the streets and
the ways adjoining the same, in good and substantial order and repair and in
such a fashion that neither the value nor utility of the Trust Premises will be
diminished, and, at its sole cost and expense, will promptly make or cause to be
made all necessary and appropriate repairs, replacements and renewals thereof,
whether interior or exterior, structural or nonstructural, ordinary or
extraordinary, foreseen or unforeseen, so that its business carried on in
connection therewith may be properly conducted at all times. The Trustor

                                    I-3-B-8
<PAGE>   12

at its expense will do or cause to be done all shoring of foundations and walls
of any building or other Improvements on the Property and (to the extent
permitted by law) of the ground adjacent thereto, and every other act necessary
or appropriate for the preservation and safety of the Property by reason of or
in connection with any excavation or other building operation upon the Property
and upon any adjoining property, whether or not the Trustor shall, by any Legal
Requirement, be required to take such action or be liable for failure to do so.

         SECTION 1.12. Alterations, Additions, etc. So long as no Event of
Default shall have occurred and be continuing, the Trustor shall have the right
at any time and from time to time to make or cause to be made reasonable
alterations of and additions to the Property or any part thereof; provided that
any alteration or addition: (a) shall not change the general character or the
use of the Property or reduce the fair market value thereof below its value
immediately before such alteration or addition, or impair the usefulness of the
Property; (b) is effected with due diligence, in a good and workmanlike manner
and in compliance in all material respects with all Legal Requirements and
Insurance Requirements; (c) subject to Section 1.8 is promptly and fully paid
for, or caused to be paid for, by the Trustor; and (d) is made, in case the
estimated cost of such alteration or addition exceeds U.S. $1,000,000, under the
supervision of a qualified architect or engineer or another professional.

         SECTION 1.13. Acquired Property Subject to Lien. Subject to the
Permitted Encumbrances and except as otherwise permitted by the Credit
Agreement, all property at any time acquired by the Trustor and provided or
required by this Deed of Trust to be or become subject to the lien and security
interest hereof, whether such property is acquired by exchange, purchase,
construction or otherwise, shall forthwith become subject to the lien and
security interest of this Deed of Trust without further action on the part of
the Trustor, the Trustee or the Beneficiary. The Trustor, at its expense, will
execute and deliver to the Trustee and Beneficiary (and will record and file as
provided in Section 1.4) an instrument supplemental to this Deed of Trust
reasonably satisfactory in substance and form to the Beneficiary, whenever such
an instrument is necessary under applicable law to subject to the lien and
security interest of this Deed of Trust all right, title and interest of the
Trustor in and to all property provided or required by this Deed of Trust to be
subject to the lien and security interest hereof.

         SECTION 1.14. Assignment of Rents, Proceeds, etc. The assignment, grant
and conveyance of the Leases, Rents, Proceeds and other rents, income, proceeds
and benefits of the Trust Premises contained in the Granting Clause of this Deed
of Trust shall constitute an absolute, present and irrevocable assignment, grant
and conveyance, provided however, that permission is hereby given to the
Trustor, so long as no Event of Default has occurred and be continuing
hereunder, to collect, receive and apply such Rents, Proceeds and other rents,
income, proceeds and benefits as they become due and payable, but not further in
advance thereof than is customary, and in accordance with all of the other
terms, conditions and provisions hereof, of the Loan Documents, and of the
Leases, contracts, agreements and other instruments with respect to which such
payments are made or such other benefits are conferred; provided, further,
however, that, to the extent required by the Credit Agreement, all such Leases,
Rents, Proceeds and other rents, income, proceeds and benefits shall be
deposited directly into the Lockbox Accounts. Upon the occurrence and
continuance of an Event of Default, such permission shall terminate immediately
and automatically, without notice to the Trustor or any other Person except as

                                    I-3-B-9
<PAGE>   13

required by law, and shall not be reinstated upon a cure of such Event of
Default without the express written consent of the Beneficiary. Such assignment
shall be fully effective without any further action on the part of the Trustor,
the Trustee, or the Beneficiary, and the Beneficiary shall be entitled, at its
option without further order of or application to the Bankruptcy Court, upon the
occurrence and continuance of an Event of Default hereunder, to collect, receive
and apply all Rents, Proceeds and all other rents, income, proceeds and benefits
from the Trust Premises, including all right, title and interest of the Trustor
in any escrowed sums or deposits or any portion thereof or interest therein,
whether or not the Trustee or the Beneficiary takes possession of the Trust
Premises or any part thereof. The Trustor further grants to the Beneficiary the
right, at the Beneficiary's option without further order of or application to
the Bankruptcy Court, upon the occurrence and continuance of an Event of Default
hereunder, to:

                  (a) enter upon and take possession of the Property for the
         purpose of collecting Rents, Proceeds and said rents, income, proceeds
         and other benefits;

                  (b) dispossess by the customary summary proceedings any
         tenant, purchaser or other Person defaulting in the payment of any
         amount when and as due and payable, or in the performance of any other
         obligation, under any Lease, contract or other instrument to which said
         Rents, Proceeds or other rents, income, proceeds or benefits relate;

                  (c) let or convey the Trust Premises or any portion thereof or
         any interest therein; and

                  (d) apply Rents, Proceeds and such rents, income, proceeds and
         other benefits, after the payment of all necessary fees, charges and
         expenses, on account of the Secured Obligations in accordance with
         Section 3.11.

         SECTION 1.15. No Claims Against the Trustee or the Beneficiary. Nothing
contained in this Deed of Trust shall constitute any consent or request by the
Trustee or the Beneficiary, express or implied, for the performance of any labor
or the furnishing of any materials or other property in respect of the Property
or any part thereof, or be construed to permit the making of any claim against
the Trustee or the Beneficiary in respect of labor or services or the furnishing
of any materials or other property or any claim that any lien based on the
performance of such labor or the furnishing of any such materials or other
property is prior to the lien and security interest of this Deed of Trust. ALL
CONTRACTORS, SUBCONTRACTORS, VENDORS AND OTHER PERSONS DEALING WITH THE
PROPERTY, OR WITH ANY PERSONS INTERESTED THEREIN, ARE HEREBY ADVISED TO TAKE
NOTICE OF THE PROVISIONS OF THIS SECTION.

         SECTION 1.16. Indemnification. The Trustor will protect, indemnify,
save harmless and defend the Trustee, the Beneficiary, the Current Assets
Lenders, and each of their respective officers, directors, shareholders,
employees, representatives and agents (collectively, the "Indemnified Parties")

                                    I-3-B-10
<PAGE>   14

agents, contractors, lessees, licensees or invitees, (g) any work in connection
with any alterations, changes, new construction or demolition of or additions to
the Property, or (h) (i) any Hazardous Material on, in, under or affecting all
or any portion of the Property, the groundwater, or any surrounding areas, (ii)
any misrepresentation, inaccuracy or breach of any warranty, covenant or
agreement contained or referred to in Sections 1.21 and 1.22, (iii) any
violation or claim of violation by the Trustor of any Environmental Laws, or
(iv) the imposition of any lien for damages caused by or the recovery of any
costs for the cleanup, release or threatened release of any Hazardous Material,
except to the extent that any of the matters described in subsections (a)-(h)
arise out of the gross negligence, unlawful acts or willful misconduct of any
Indemnified Party. THE TRUSTEE SHALL NOT BE LIABLE FOR ANY ACT OR OMISSION OR
ERROR OF JUDGMENT IN CONNECTION WITH THIS DEED OF TRUST, IT BEING THE INTENT OF
THE PARTIES HERETO THAT THE TRUSTEE SHALL NOT BE LIABLE FOR THE TRUSTEE'S SOLE
OR CONTRIBUTORY NEGLIGENCE. TRUSTOR SHALL AND DOES INDEMNIFY THE TRUSTEE AGAINST
ALL LOSSES, DAMAGES, LIABILITIES, CLAIMS, CAUSES OF ACTION, JUDGMENTS, COURT
COSTS, ATTORNEYS FEES AND EXPENSES THAT THE TRUSTEE MAY INCUR IN THE PERFORMANCE
OF THE TRUSTEE'S DUTIES HEREUNDER OR OTHERWISE IN CONNECTION WITH THIS DEED OF
TRUST WHETHER OR NOT SAME RESULT FROM THE SOLE OR CONTRIBUTORY NEGLIGENCE OF THE
TRUSTEE. THE FOREGOING SHALL ALSO APPLY TO ANY SUBSTITUTE TRUSTEE HEREUNDER. If
any action or proceeding be commenced, to which action or proceeding any
Indemnified Party is made a party by reason of the execution of this Deed of
Trust or any other Loan Document pertaining to the Current Assets Loans, or in
which it becomes necessary to defend or uphold the lien of this Deed of Trust,
all sums paid by the Indemnified Parties, for the expense of any litigation to
prosecute or defend the rights and lien created hereby or otherwise, shall be
paid by the Trustor to such Indemnified Parties, as the case may be, as
hereinafter provided. The Trustor will pay and save the Indemnified Parties
harmless against any and all liability with respect to any intangible personal
property tax or similar imposition of the State or any subdivision or authority
thereof now or hereafter in effect, to the extent that the same may be payable
by the Indemnified Parties in respect of this Deed of Trust, any Loan Document
pertaining to the Current Assets Loans or any Secured Obligation. All amounts
payable to the Indemnified Parties under this Section 1.16 shall be deemed
indebtedness secured by this Deed of Trust and any such amounts which are not
paid within ten (10) days after written demand therefor by any Indemnified Party
shall bear interest at the rate provided for in Section 3.2.2 of the Credit
Agreement from the date of such demand. In case any action, suit or proceeding
is brought against any Indemnified Party by reason of any such occurrence, the
Trustor, upon request of such Indemnified Party, will, at the Trustor's expense,
resist and defend such action, suit or proceeding or cause the same to be
resisted or

                                    I-3-B-11
<PAGE>   15

defended by counsel designated by the Trustor and approved by such Indemnified
Party. The obligations of the Trustor under this Section 1.16 shall survive any
discharge or reconveyance of this Deed of Trust and payment in full of the
Secured Obligations.

         SECTION 1.17. No Credit for Payment of Taxes. The Trustor shall not be
entitled to any credit against the Secured Obligations by reason of the payment
of any tax on the Property or any part thereof or by reason of the payment of
any other Imposition, and shall not apply for or claim any deduction from the
taxable value of the Property or any part thereof by reason of this Deed of
Trust.

         SECTION 1.18. Intentionally Omitted.

         SECTION 1.19. No Transfer of the Property. Except as is provided in the
Credit Agreement, and except for the Permitted Encumbrances, the Trustor shall
not, without the prior written consent of the Beneficiary, which consent may be
granted or withheld in the sole and absolute discretion of the Beneficiary, (i)
sell, convey, assign or otherwise transfer the Property or any portion of the
Trustor's interest therein or (ii) further encumber the Property or permit the
Property to become encumbered by any lien, claim, security interest or other
indebtedness of any kind or nature other than the Permitted Encumbrances.

         SECTION 1.20. Security Agreement. With respect to the items of personal
property and fixtures referred to and described in the Granting Clause of this
Deed of Trust and included as part of the Trust Premises, this Deed of Trust is
hereby made and declared to be a security agreement encumbering each and every
item of personal property and fixtures now or hereafter owned by Trustor and
included herein as a part of the Trust Premises, in compliance with the
provisions of the Uniform Commercial Code as enacted in the State. In this
respect (and notwithstanding the conveyance to the Trustee rather than directly
to the Beneficiary as provided in this Deed of Trust), Trustor, as "Debtor",
expressly grants to Beneficiary, as "Secured Party", a security interest in and
to all of the property now or hereafter owned by Trustor which constitutes the
personal property and fixtures hereinabove referred to and described in this
Deed of Trust, including all extensions, accessions, additions, improvements,
betterments, renewals, replacements and substitutions thereof or thereto, and
all proceeds from the sale or other disposition thereof. Trustor agrees that
Beneficiary may file this Deed of Trust, or a reproduction thereof, in the real
estate records or other appropriate index, as, and this Deed of Trust shall be
deemed to be, a financing statement filed as a fixture filing in accordance with
the laws of the State. Any reproduction of this Deed of Trust or of any other
security agreement or financing statement executed by Trustor shall be
sufficient as a financing statement. In addition, Trustor agrees to execute and
deliver to Beneficiary, upon Beneficiary's request, any other security agreement
and financing statements, as well as extensions, renewals, and amendments
thereof, and reproductions of this Deed of Trust, in such form as Beneficiary
may reasonably require to perfect a security interest with respect to said
items. Trustor shall pay all costs of filing such financing statements and any
extensions, renewals, amendments and releases thereof, and shall pay all
reasonable costs and expenses of any record searches for financing statements
Beneficiary may reasonably require. Except as is provided in the Credit
Agreement, and except for the Permitted Encumbrances, without the prior written
consent of Beneficiary, Trustor shall not create or suffer to be created
pursuant to the Uniform Commercial Code any other security

                                    I-3-B-12

interest in the above-described personal property and fixtures, including any
replacements and additions thereto. Upon the occurrence and continuance of an
Event of Default under this Deed of Trust, the Beneficiary shall have and shall
be entitled to exercise any and all of the rights and remedies (i) as prescribed
in this Deed of Trust, or (ii) as prescribed by general law, or (iii) as
prescribed by the specific statutory provisions now or hereafter enacted and
specified in said Uniform Commercial Code, all at Beneficiary's sole election.
Trustor and Beneficiary agree that the filing of any financing statements in the
records normally having to do with personal property shall not in any way affect
the agreement of Trustor and Beneficiary that everything located in, on or
about, or used or intended to be used with or in connection with the use,
operation or enjoyment of, the Trust Premises, which is described or reflected
as a fixture in this Deed of Trust, is, and at all times and for all purposes
and in all proceedings, both legal and equitable, shall be, regarded as part of
the Real Estate conveyed hereby. Trustor warrants that Trustor's name, identity
and address are as set forth herein. The mailing address of the Beneficiary from
which information may be obtained concerning the security interest created
herein is also set forth herein. This information hereof is provided in order
that this Deed of Trust shall comply with the requirements of the Uniform
Commercial Code as enacted in the State for instruments to be filed as financing
statements. In accordance with the laws of the State, this Deed of Trust shall
remain effective as a fixture filing until this Deed of Trust is released or
satisfied of record or its effectiveness otherwise terminates as to the Trust
Premises.

         SECTION 1.21. Representations and Warranties. In order to induce the
Beneficiary to enter into this Deed of Trust, the Credit Agreement and the other
Loan Documents pertaining to the Current Assets Loans, the Trustor agrees that
all of the representations and warranties of Trustor set forth in the Credit
Agreement are incorporated into this Deed of Trust by reference as if fully set
forth herein.

         SECTION 1.22. Trustor's Covenants. In order to induce the Beneficiary
to enter into this Deed of Trust, the Credit Agreement and the other Loan
Documents pertaining to the Current Assets Loans, the Trustor agrees that all of
the covenants of Trustor set forth in the Credit Agreement are incorporated into
this Deed of Trust by reference as if fully set forth herein.

         SECTION 1.23. Attornment. Beneficiary hereby acknowledges and agrees
that the liens granted herein are subject to the rights of certain lessees under
the Leases as disclosed in the Credit Agreement and will be subject to the
rights of lessees under any Leases entered into by Trustor after the date hereof
which are permitted as Permitted Real Estate Liens pursuant to the Credit
Agreement, subject to the express rights contained in the applicable Lease. The
rights of the tenants under the Leases to the leased premises shall not be
adversely affected by the exercise by Beneficiary of any of its rights
hereunder, nor shall any such tenant be in any other way deprived of its rights
under the applicable Lease except in accordance with the terms of such Lease. In
the event that Beneficiary succeeds to the interest of Trustor under a Lease,
such Lease shall not be terminated or affected thereby except as set forth
therein, and any sale of the applicable leased premises by Beneficiary or
pursuant to the judgment of any court in an action to enforce the remedies
provided for in this Deed of Trust shall be made subject to such Lease and the
rights of such tenant expressly set forth thereunder. If Beneficiary succeeds to
the interests of Trustor in and to the applicable leased premises or under such
Lease or enters into

                                    I-3-B-13
<PAGE>   17

possession of such leased premises, the Beneficiary, and such tenants, shall be
bound to each other under all of the express terms, covenants and conditions of
such Lease, as if the Beneficiary was originally the Trustor as lessor
thereunder.

<PAGE>   19

                  (b) any taking, whether for permanent or temporary use, of all

policy required to be maintained by the Trustor hereunder and all awards

maintained by the Trustor to be applied pursuant to the provisions of the Credit
Agreement.

         Notwithstanding the foregoing provisions of this Section 2.3 to the
contrary (but subject to the provisions of Section 2.4), and if each of the
following conditions is satisfied, the Beneficiary, upon request of the Trustor,
may apply up to $5,000,000 of insurance proceeds or condemnation awards received
by it toward the restoration or replacement of the affected Collateral, to the
extent necessary for the restoration or replacement thereof; provided that:

                           (i) no Default or Event of Default then exists;

                           (ii) the Trustor shall have furnished to the
                  Beneficiary a certificate of an architect or engineer
                  reasonably acceptable to the Beneficiary stating (x) that the
                  affected Collateral is capable of being restored, prior to the
                  maturity of the Credit Agreement, to substantially the same
                  condition as existed prior to the casualty, (y) the aggregate
                  estimated direct and indirect costs of such restoration and
                  (z) as to any Taking, that the property taken in such Taking,
                  or sold under threat thereof, is not necessary to the
                  Trustor's customary use or occupancy of the Property or
                  Trustor otherwise provides Beneficiary adequate assurance that
                  the Collateral can be restored; and

                                    I-3-B-16
<PAGE>   20

                           (iii) in the event that the estimated cost of
                  restoration set forth in the certificate of such architect or
                  engineer (and such revisions to such estimate as are from time
                  to time made) exceeds maximum amount of insurance proceeds or
                  condemnation awards that would be permitted to be applied to
                  the restoration or replacement of the Collateral pursuant to
                  the foregoing, the Trustor shall deposit the amount of such
                  excess with the Beneficiary.

         In the event that, after the restoration or replacement of the Trust
Premises, any insurance or condemnation awards shall remain, such amount shall
be deposited in a Lockbox Account to be applied pursuant to the provisions of
the Credit Agreement. If, prior to the receipt by the Beneficiary of such
insurance proceeds or condemnation awards, the Trust Premises shall have been
sold on foreclosure, the Beneficiary shall have the right to receive said
insurance proceeds or condemnation awards to the extent of any deficiency found
to be due upon such sale, with legal interest thereon, whether or not a
deficiency judgment shall have been sought or recovered or denied, and the
reasonable attorneys' fees, costs and disbursements incurred by the Beneficiary
in connection with the collection of such award or payment.

                  SECTION 2.4. Total Taking and Total Destruction. Subject to
any applicable requirements of the Financing Order, the Credit Agreement and the
Revolver Intercreditor Agreement, in the event of a Total Destruction or a Total
Taking, the Beneficiary shall apply all amounts recovered under any insurance
policy referred to in Section 2.1.1 and all awards received by it on account of
any such Taking shall be deposited in a Lockbox Account maintained by the
Trustor to be applied pursuant to the provisions of the Credit Agreement.

                                   ARTICLE III

applicable requirements of the Financing Order, the Credit Agreement and the
Revolver Intercreditor Agreement, at any time thereafter (unless all Events of

all of which the Trustor hereby waives. The Trustor will pay on demand all costs
and expenses, including without limitation, attorneys' fees and expenses,
incurred by or on behalf of the Beneficiary in enforcing this Deed of Trust, or
any other Loan Document evidencing or securing the Current Assets Loans, or
occasioned by any default hereunder or thereunder.

         SECTION 3.2. Legal Proceeding; Judicial Foreclosure. If an Event of
Default shall have occurred and be continuing, the Trustee at any time may, at
its election and without further order

<PAGE>   21

of or application to the Bankruptcy Court, but subject to any applicable
requirements of the Financing Order, the Credit Agreement and the Revolver
Intercreditor Agreement, proceed at law or in equity or otherwise to enforce the
payment and performance of the Secured Obligations in accordance with the terms
hereof and thereof and to foreclose the lien of this Deed of Trust as against
all or any part of the Trust Premises and to have the same sold under the
judgment or decree of a court of competent jurisdiction. The Beneficiary shall
be entitled to recover in such proceedings all costs incident thereto, including
the Trustee's fees and attorneys' fees and expenses in such amounts as may be
fixed by the court.

         SECTION 3.3. Power of Sale. If an Event of Default shall have occurred
and be continuing, the Beneficiary may, without further order of or application
to the Bankruptcy Court, sell or offer for sale the Trust Premises in such
portions, order and parcels as the Beneficiary may determine, with or without
having first taken possession of the same, to the highest bidder for cash at
public auction. Such sale shall be made at the courthouse of the county wherein
the Land (or any of that portion thereof to be sold) is situated (whether the
parts or parcels thereof, if any, in different counties are contiguous or not
and without the necessity of having any personal property hereby mortgaged

notice, enclosed in a postpaid wrapper, properly stamped and addressed to such
debtor at the most recent address as shown by the records of the Beneficiary, in
a post office or official depository under the care and custody of the United
States. It is agreed that the posting and transmittal of notices may be
performed by the Trustee, Beneficiary, or by any person acting for them. In lieu
of the foregoing, the sale may be accomplished by following the procedures
permitted or required by Section 51.002 of the Texas Properly Code, as same may
be amended from time to time, relating to the sale of real estate and/or by the
Texas Uniform Commercial Code-Secured Transactions (same being Chapter 9 of the
Texas Business and Commerce Code) relating to the sale of personal property
collateral after default by a debtor (as said Section and Chapter may now exist
or may hereafter be amended or succeeded), or by any other present or subsequent
articles or enactments relating to the same. Nothing contained in this Section
shall be construed to limit in any way the Trustee's rights to sell the Trust
Premises by private sale if, and to the extent, that such private sale is
permitted under the laws of the State or by public or private sale after entry
of judgment by any court of competent jurisdiction ordering the same. At any
such sale (i) whether made under power herein contained, Section 51.002 of the
Texas Property Code, the Texas Uniform Commercial Code-Secured Transactions, any
other legal requirement or by virtue of any judicial procedure or any other
legal right, remedy or recourse, it shall not be necessary for the Trustee to
have physically present, or to have constructive possession of, the Trust
Premises (Trustor hereby covenanting and agreeing to deliver to the Trustee any
portion of the Trust Premises not actually or constructively possessed by the
Trustee immediately upon demand by the Trustee), and the title to and right of
possession

                                    I-3-B-18
<PAGE>   22

of any such property shall pass to the purchaser thereof as completely as if the
same had been actually present and delivered to purchaser at such sale, (ii)
each instrument of conveyance executed by the Trustee shall contain a special
warranty of title, binding upon Trustor, (iii) each and every recital contained
in any instrument of conveyance made by the Trustee shall conclusively establish
the truth and accuracy of the matters recited therein, including, without
limitation, nonpayment of the Secured Obligations, advertisement and conduct of
such sale in the manner provided herein and otherwise by law and appointment of
any successor to the Trustee hereunder, (iv) any and all prerequisites to the
validity thereof shall be conclusively presumed to have been performed, (v) the
receipt of the Trustee or of such other party or officer making the sale shall
be a sufficient discharge to the purchaser or purchasers for his or their
purchase money and no such purchaser or purchasers, or his or their assigns or
personal representatives, shall thereafter be obligated to see to the
application of such purchase money or be in any way answerable for any loss,
misapplication or nonapplication thereof, (vi) to the fullest extent permitted
by law, Trustor shall be completely and irrevocably divested of all of its
right, title, interest, claim and demand whatsoever, either at law or in equity,
in and to the property sold and such sale shall be a perpetual bar, both at law
and in equity, against Trustor, and against any and all other persons claiming
or to claim the property sold or any pant thereof, by, through or under Trustor,
and (vii) to the extent and under such circumstances as are permitted by law,
Beneficiary may be a purchaser at any such sale. The Trust Premises may be sold
in one or more parcels and in such manner and order as Trustee, in its sole
discretion, may elect, it being expressly understood and agreed that the right
of sale arising out of any Event of Default shall not be exhausted by any one or
more sales but other and successive sales may be made until all of the Trust
Premises have been sold or until the Secured Obligations have been fully
satisfied. In case Beneficiary shall have proceeded to invoke any right, remedy
or recourse permitted under this Deed of Trust and shall thereafter elect to
discontinue or abandon the same for any reason, Beneficiary shall have the
unqualified right so to do and, in such event, Trustor and Beneficiary shall be
restored to their former positions with respect to the Secured Obligations, the
Trust Premises and otherwise, and the rights, remedies, recourses and powers of
Beneficiary shall continue as if same had never been invoked.

         SECTION 3.4. Uniform Commercial Code Remedies. If an Event of Default
shall have occurred and be continuing, the Beneficiary may, without further
order of or application to the Bankruptcy Court, but subject to any applicable
requirements of the Financing Order, the Credit Agreement and the Revolver
Intercreditor Agreement, exercise from time to time and at any time any rights
and remedies available to it under applicable law upon default in the payment of
indebtedness, including, without limitation, any right or remedy available to it
as a secured party under the Uniform Commercial Code of the State. The Trustor
shall, promptly upon request by the Trustee or the Beneficiary, assemble the
Trust Premises, or any portion thereof generally described in such request, and
make it available to the Trustee or the Beneficiary, at such place or places
designated by the Trustee or the Beneficiary, and reasonably convenient to the
Trustee or the Beneficiary. If the Beneficiary elects to proceed under the
Uniform Commercial Code of the State to dispose of portions of the Trust
Premises, the Trustee or the Beneficiary, at their respective option, may give
the Trustor notice of the time and place of any public sale of any such
property, or of the date after which any private sale or other disposition
thereof is to be made, by sending notice by registered or certified first class
mail, postage prepaid, to the Trustor at least ten (10) days before the time of
the sale or other disposition. If any notice of any

                                    I-3-B-19
<PAGE>   23

proposed sale, assignment or transfer by the Beneficiary of any portion of the
Trust Premises or any interest therein is required by law, the Trustor
conclusively agrees that ten (10) days notice to the Trustor of the date, time
and place (and, in the case of a private sale, the terms) thereof is reasonable.

         SECTION 3.5. Trustee and Beneficiary Authorized to Execute Deeds, etc.
The Trustor irrevocably appoints the Trustee and the Beneficiary (which
appointment is coupled with an interest) the true and lawful attorney of the
Trustor, in its name and stead and on its behalf, for the purpose of
effectuating any sale, assignment, transfer or delivery for the enforcement
hereof, whether pursuant to power of sale, foreclosure or otherwise, to execute
and deliver all such deeds, bills of sale, assignments, releases and other
instruments as may be designated in any such request.

         SECTION 3.6. Purchase of Trust Premises by Beneficiary. The Beneficiary
may be a purchaser of the Trust Premises or of any part thereof or of any
interest therein at any sale thereof, whether pursuant to power of sale,
foreclosure or otherwise, and the Beneficiary may apply upon the purchase price
thereof the indebtedness secured hereby owing to the Beneficiary. Such purchaser
shall, upon any such purchase, acquire good title to the properties so

otherwise and may remove the Trustor and all other Persons and any and all
property therefrom and may hold, operate, maintain, repair, preserve and manage
the same and receive all earnings, income, Rents, issues and Proceeds accruing
with respect thereto or any part thereof. The Trustee and the Beneficiary shall
be under no liability for or by reason of any such taking of possession, entry,
removal or holding, operation or management, except that any amounts so received
by the Trustee or the Beneficiary shall be applied to pay all costs and expenses
of so entering upon, taking possession of; holding, operating, maintaining,

Covenants, etc. If the Trustor shall fail to make any payment or perform any act

pertaining to the Current Assets Loans or any other Loan Document pertaining to
the Current Assets Loans, the Beneficiary, without further order of or
application to the Bankruptcy Court, without notice to or demand upon the
Trustor and without waiving or releasing any obligation or Event of Default, may
(but shall be under no obligation to) at any time thereafter make such payment
or perform such act for the account and at the expense of the Trustor, and may
enter upon the Trust Premises for such purpose and take all such action thereon
as, in either the Trustee's or the Beneficiary's opinion, may be necessary or
appropriate therefor. No such entry and no such action shall be deemed an
eviction of any lessee of the Property or any part thereof. All sums so paid by
the Trustee or the Beneficiary, and all costs and expenses (including, without
limitation, attorneys' fees and expenses) so incurred, together with interest
thereon at the rate provided for in Section 3.2.2 of the Credit Agreement from
the date of payment or incurring, shall constitute additional indebtedness under

Trustor to the Trustee or the Beneficiary, as the case may be, on demand.

the Beneficiary, on or after the date hereof, pays any sum due under any
provision of any Legal Requirement or any instrument creating any lien prior or

pays any such sum with the proceeds of the Current Assets Loans, the Trustee
and/or the Beneficiary shall have and be entitled to a lien on the Trust
Premises equal in priority to the lien discharged, and the Trustee and/or the
Beneficiary shall be subrogated to, and

                                    I-3-B-22
<PAGE>   26

receive and enjoy all rights and liens possessed, held or enjoyed by, the holder
of such lien, which shall remain in existence and benefit the Beneficiary in
securing the Secured Obligations.

         SECTION 3.16. Remedies, etc. Cumulative. Each right, power and remedy
of the Trustee and/or the Beneficiary provided for in this Deed of Trust, the
Credit Agreement pertaining to the Current Assets Loans, or any other Loan
Document pertaining to the Current Assets Loans, or now or hereafter existing at
law or in equity or by statute or otherwise shall be cumulative and concurrent
and shall be in addition to every other right, power or remedy provided for in
this Deed of Trust, the Credit Agreement or any other Loan Document pertaining
to the Current Assets Loans, or now or hereafter existing at law or in equity or
by statute or otherwise, and the exercise or beginning of the exercise by the
Trustee or the Beneficiary of any one or more of the rights, powers or remedies
provided for in this Deed of Trust, the Credit Agreement, or any other Loan
Document pertaining to the Current Assets Loans, or now or hereafter existing at
law or is equity or by statute or otherwise shall not preclude the simultaneous
or later exercise by the Trustee or the Beneficiary of any or all such other
rights, powers or remedies.

         SECTION 3.17. Provisions Subject to Applicable Law. All rights, powers
and remedies provided in this Deed of Trust may be exercised only to the extent
that the exercise thereof does not violate any applicable provisions of law and
are intended to be limited to the extent necessary so that they will not render
this Deed of Trust invalid, unenforceable or not entitled to be recorded,
registered or filed under the provisions of any applicable law. If any term of
this Deed of Trust or any application thereof shall be invalid or unenforceable,
the remainder of this Deed of Trust and any other application of such term shall
not be affected thereby.

         SECTION 3.18. No Waiver, etc. No failure by the Trustee or the
Beneficiary to insist upon the strict performance of any term hereof or of the
Credit Agreement, or of any other Loan Document, or to exercise any right, power
or remedy consequent upon a breach hereof or thereof, shall constitute a waiver
of any such term or of any such breach. No waiver of any breach shall affect or
alter this Deed of Trust, which shall continue in full force and effect with
respect to any other then existing or subsequent breach. By accepting payment or
performance of any amount or other Secured Obligations secured hereby before or
after its due date, neither the Trustee nor the Beneficiary shall be deemed to
have waived its right either to require prompt payment or performance when due
of all other amounts and Secured Obligations payable hereunder or to declare a
default for failure to effect such prompt payment.

         SECTION 3.19. Compromise of Actions, etc. Any action, suit or
proceeding brought by the Trustee or the Beneficiary pursuant to any of the
terms of this Deed of Trust, the Credit Agreement pertaining to the Current
Assets Loans, any other Loan Document pertaining to the Current Assets Loans, or
otherwise, and any claim made by the Trustee or the Beneficiary hereunder or
thereunder, may be compromised, withdrawn or otherwise dealt with by the Trustee
or the Beneficiary without any notice to or approval of the Trustor.

         continuing,

                           (1) the Trustee shall not be liable except for the

                  shall be read into this Deed of Trust against the Trustee,
                  whose duties and obligations shall be determined solely by the
                  express provisions of this Deed of Trust, and

                           (2) in the absence of bad faith on the part of the
                  Trustee, the Trustee may conclusively rely, as to the truth of

                  therein, upon certificates or opinions conforming to the
                  requirements of this Deed of Trust;

                  (b) the Trustee shall not be liable for any error of judgment
         made in good faith by an officer or officers of the Trustee, unless it
         shall be proved that the Trustee was negligent in ascertaining the
         pertinent facts;

         hereby created by giving written notice thereof to the Trustor and to
         the Beneficiary. Such resignation shall become effective upon the
         appointment of its successor and such successor's acceptance of such
         appointment, provided that, if a successor Trustee has not been so
         appointed, or, if so appointed, has not accepted the appointment within
         thirty (30) days after the date of such written notice of resignation,
         the Trustee may apply to any court of competent jurisdiction for the

         originally herein named or any successor. Each such substitution shall
         be executed and acknowledged, and notice thereof shall be given and
         proof thereof made in accordance with applicable law. The Trustor

         WILL BE DEEMED TO PRECLUDE EITHER OF THE TRUSTEE OR THE BENEFICIARY
         FROM BRINGING AN ACTION AGAINST THE TRUSTOR IN ANY OTHER JURISDICTION.

         SECTION 5.13. Severability; Conflicts. Any provision of this Deed of
Trust, the Credit Agreement or any other Loan Document pertaining to the Current
Assets Loans which is prohibited or unenforceable in any jurisdiction shall as
to such provision and such jurisdiction, be ineffective to the extent of such
prohibition or unenforceability without invalidating the remaining provisions of
this Deed of Trust, the Credit Agreement or such Loan Document pertaining to the
Current Assets Loans or affecting the validity or enforceability of such
provision in any other jurisdiction. In the event of any conflict between the
terms of this Deed of Trust and the terms of the Credit Agreement, the terms of
the Credit Agreement shall control.

         SECTION 5.14 Loan Document. This Deed of Trust is a Loan Document
executed pursuant to the Credit Agreement and, unless otherwise expressly
indicated herein, shall be construed, administered and applied in accordance
with the terms and provisions thereof.

         SECTION 5.15. Usury Savings Clause. In no event shall any provision of
this instrument, the Current Assets Notes, or any other instrument evidencing or
securing the Secured

                                    I-3-B-31
<PAGE>   35

Obligations ever obligate Trustor to pay or allow Beneficiary to collect
interest on the Current Assets Notes or any other Secured Obligations secured
hereby at a rate greater than the maximum non-usurious rate permitted by
applicable law (herein referred to as the "Highest Lawful Rate"), or obligate
Trustor to pay any amounts that would be held or deemed to constitute interest
under applicable law which, when added to the interest payable on the Current
Assets Notes, would be held to constitute the payment by Trustor of interest at
a rate greater than the Highest Lawful Rate; and this provision shall control
over any provision to the contrary. To the extent the Highest Lawful Rate is
determined by reference to the laws of the State of Texas, same shall be
determined by reference to the indicated rate ceiling (as defined and described
in Chapter 303 of the Texas Finance Code, as amended) at the applicable time in
effect.

                  Without limiting the generality of the foregoing, in the event
the maturity of all or any part of the principal amount of the Secured
Obligations shall be accelerated for any reason, then such principal amount so
accelerated shall be credited with any interest theretofore paid thereon in
advance and remaining unearned at the time of such acceleration. If, pursuant to
the terms of this Deed of Trust or the Current Assets Notes, any funds are
applied to the payment of any part of the principal amount of the Secured
Obligations prior to the maturity thereof, then (a) any interest which would
otherwise thereafter accrue on the principal amount so paid by such application
shall be canceled, and (b) the Secured Obligations remaining unpaid after such
application shall be credited with the amount of all interest, if any,
theretofore collected on the principal amount so paid by such application and
remaining unearned at the date of said application; and if the funds so applied
shall be sufficient to pay in full all the Secured Obligations, then Beneficiary
shall refund to Trustor all interest theretofore paid thereon in advance and
remaining unearned at the time of such acceleration. Regardless of any other
provision in this instrument, or in any of the written evidences of the Secured
Obligations, Trustor shall never be required to pay any unearned interest on the
Secured Obligations or any portion thereof, and shall never be required to pay
interest thereon at a rate in excess of the Highest Lawful Rate construed by
courts having competent jurisdiction thereof.

         SECTION 5.16. Future Advances. This Deed of Trust is a "Future Advance
Deed of Trust" under the laws of the State. Any and all future advances under
this Deed of Trust and the Loan Documents pertaining to the Current Assets Loans
shall have the same priority as if the future advance was made on the date that
this Deed of Trust was recorded. This Deed of Trust shall secure the Secured
Obligations, whenever incurred, such Secured Obligations to be due at the times
provided in the Loan Documents pertaining to the Current Assets Loans. Notice is
hereby given that the Secured Obligations may increase as a result of any
defaults hereunder by Trustor due to, for example, and without limitation,
unpaid interest or late charges, unpaid taxes or insurance premiums which the
Beneficiary elects to advance, defaults under leases that the Beneficiary elects
to cure, attorney fees or costs incurred in enforcing the Loan Documents
pertaining to the Current Assets Loans or other expenses incurred by the
Beneficiary in protecting the Trust Premises, the security of this Deed of Trust
or the Beneficiary's rights and interests.

         SECTION 5.17. Deed of Trust Subject to Revolver Intercreditor
Agreement. Notwithstanding anything to the contrary contained herein, it is
expressly understood and agreed

                                    I-3-B-32
<PAGE>   36

by the parties hereto that this Deed of Trust shall be subject to the terms of
the Revolver Intercreditor Agreement.

         SECTION 5.18. Entire Agreement. THIS WRITTEN LOAN AGREEMENT REPRESENTS
THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE
OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.

         THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

         Pursuant to the procedure set forth in Florida Department of Revenue
         Regulation 12B-4.053(32)(c) the documentary stamp tax due on the
         indebtedness secured hereby is $50,855.00 which is based on a value of
         the Florida real estate secured hereby in the amount of $14,530,000.00
         and based on the hereinafter calculations.

         Based on the valuations of the collateral as a ratio set forth in the
         Florida Department of Revenue Regulation 12C-2.004(2) the intangible
         tax due on the indebtedness secured and allocated to Florida real
         estate is $1,660.15. This is based upon a total value for all Florida
         real estate of $14,530,000.00 and the value of all collateral in the
         amount of $1,225,309,000.00.

such statutes and regulations as may be required by law in order to establish,
preserve, perfect and protect the lien and security interest of this Mortgage as

paid, and will indemnify the Mortgagee in respect of, all taxes (including
interest and penalties) at any time payable in connection with the filing and
recording of this Mortgage and any and all supplements and amendments hereto.

         SECTION 1.5. Payment of Impositions, etc. Subject to Section 1.8

operation, use, possession or activities thereof, whether any or all of the same
be levied directly or indirectly or as excise taxes or as income taxes, and all
taxes, assessments or charges which may be levied on the Secured Obligations, or
the interest thereon (collectively, the "Impositions"). The Mortgagor will
deliver to the Mortgagee, upon request, copies of official receipts or other
satisfactory proof evidencing such payments.

         streets or ways, or any use or condition of the Collateral or any part
         thereof (collectively, the "Legal Requirements");

noncompliance of which could reasonably be expected to cause a Material Adverse
Effect whether or not compliance therewith shall require structural changes in
or interference with the use and enjoyment of the Collateral or any part
thereof.

         SECTION 1.7. Security Interests, etc. The Mortgagor will not directly
or indirectly create or permit or suffer to be created or to remain, and will

therein, or any Proceeds thereof or Rents or other sums arising therefrom, other
than (a) Permitted Encumbrances, and (b) liens of mechanics, materialmen,
suppliers or vendors or rights thereto incurred in the ordinary course of the
business of the Mortgagor for sums not yet due or any such liens or rights
thereto which are at the time being contested as permitted by Section 1.8. The
Mortgagor will not postpone the payment of any sums for which liens of
mechanics, materialmen, suppliers or vendors or rights thereto have been
incurred (unless such liens or rights thereto are at the time being contested as
permitted by Section 1.8), for more than 60 days after the completion of the
action giving rise to such liens or rights thereto.

         SECTION 1.8. Permitted Contests. The Mortgagor at its expense may
contest, or cause to be contested, by appropriate legal proceedings conducted in
good faith and with due diligence, the amount or validity or application, in
whole or in part, of any Imposition, Legal Requirement or Insurance Requirement
or lien of a mechanic, materialman, supplier or vendor, provided that, (a) in
the case of an unpaid Imposition, lien, encumbrance or charge, such proceedings
shall suspend the collection thereof from the Mortgagor, the Mortgagee, and the
Collateral (including any rent or other income therefrom) and shall not
materially interfere with the payment of any such rent or income, (b) neither
the Collateral nor any rent or other income therefrom nor any part thereof or
interest therein would be in any material danger of being sold, forfeited, lost,
impaired or interfered with, (c) in the case of a Legal Requirement, neither the
Mortgagor nor the Mortgagee would be in material danger of any civil or criminal
liability for failure to comply therewith, (d) the Mortgagor shall have
furnished such security, if any, as may be required in the proceedings or as may
be reasonably requested by the Mortgagee, (e) the non-payment of the whole or
any part of any Imposition will not result in the delivery of a tax deed to the
Collateral or any part thereof because of such non-payment, (f) the payment of
any sums required to be paid with respect to any of the Fixed Asset Notes or
under this Mortgage (other than any unpaid

                                    I-1-A-7
<PAGE>   12

Imposition, lien, encumbrance or charge at the time being contested in
accordance with this Section 1.8) shall not be interfered with or otherwise
affected, (g) in the case of any Insurance Requirement, the failure of the
Mortgagor to comply therewith shall not affect the validity of any insurance
required to be maintained by the Mortgagor under Section 2.1, and (h) that
adequate reserves, determined in accordance with GAAP, shall have been set aside
on the Mortgagor's books.

         SECTION 1.9. Leases. The Mortgagor represents and warrants to the
Mortgagee that, as of the date hereof, there are no written or oral leases or
other agreements of any kind or nature relating to the occupancy of any portion
of the Property by any Person other than the Mortgagor other than the Permitted
Encumbrances. Except as is permitted by the Credit Agreement, the Mortgagor will
not enter into any such written or oral lease or other agreement with respect to
any portion of the Property without first obtaining the written consent of the
Mortgagee.

         SECTION 1.10. Compliance with Instruments. The Mortgagor at its expense
will promptly comply in all material respects with all rights of way or use,
privileges, franchises, servitudes, licenses, easements, tenements,
hereditaments and appurtenances forming a part of the Property and all
instruments creating or evidencing the same, in each case, to the extent
compliance therewith is required of the Mortgagor under the terms thereof.
Except as is permitted by the Credit Agreement, the Mortgagor will not take any
action which may result in a forfeiture or termination of the rights afforded to
the Mortgagor under any such instruments and will not, without the prior written
consent of the Mortgagee, amend any of such instruments in any manner adverse to
the Fixed Assets Lenders in any material respect.

         SECTION 1.11. Maintenance and Repair, etc. Subject to the provisions of
Section 1.12, the Mortgagor will keep or cause to be kept all presently and
subsequently erected or acquired Improvements and the sidewalks, curbs, vaults
and vault space, if any, located on or adjoining the same, and the streets and
the ways adjoining the same, in good and substantial order and repair and in
such a fashion that neither the value nor utility of the Collateral will be
diminished, and, at its sole cost and expense, will promptly make or cause to be
made all necessary and appropriate repairs, replacements and renewals thereof,
whether interior or exterior, structural or nonstructural, ordinary or
extraordinary, foreseen or unforeseen, so that its business carried on in
connection therewith may be properly conducted at all times. The Mortgagor at
its expense will do or cause to be done all shoring of foundations and walls of
any building or other Improvements on the Property and (to the extent permitted
by law) of the ground adjacent thereto, and every other act necessary or
appropriate for the preservation and safety of the Property by reason of or in
connection with any excavation or other building operation upon the Property and
upon any adjoining property, whether or not the Mortgagor shall, by any Legal
Requirement, be required to take such action or be liable for failure to do so.

         SECTION 1.12. Alterations, Additions, etc. So long as no Event of
Default shall have occurred and be continuing, the Mortgagor shall have the
right at any time and from time to time to make or cause to be made reasonable
alterations of and additions to the Property or any part thereof, provided that
any alteration or addition: (a) shall not change the general character or the
use of the Property or reduce the fair market value thereof below its value
immediately before such alteration or addition, or impair the usefulness of the
Property; (b) is effected with due diligence, in a good and workmanlike manner
and in compliance in all material respects with all

                                    I-1-A-8
<PAGE>   13

Legal Requirements and Insurance Requirements; (c) subject to Section 1.8 is
promptly and fully paid for, or caused to be paid for, by the Mortgagor; and (d)
is made, in case the estimated cost of such alteration or addition exceeds U.S.
$1,000,000, under the supervision of a qualified architect or engineer or
another professional.

         SECTION 1.13. Acquired Property Subject to Lien. Subject to the
Permitted Encumbrances, all property at any time acquired by the Mortgagor and
provided or required by this Mortgage to be or become subject to the lien and
security interest hereof, whether such property is acquired by exchange,
purchase, construction or otherwise, shall forthwith become subject to the lien
and security interest of this Mortgage without further action on the part of the
Mortgagor or the Mortgagee. The Mortgagor, at its expense, will execute and
deliver to the Mortgagee (and will record and file as provided in Section 1.4)
an instrument supplemental to this Mortgage reasonably satisfactory in substance
and form to the Mortgagee, whenever such an instrument is necessary under
applicable law to subject to the lien and security interest of this Mortgage all
right, title and interest of the Mortgagor in and to all property provided or
required by this Mortgage to be subject to the lien and security interest
hereof.

         SECTION 1.14. Assignment of Rents, Proceeds, etc. The assignment, grant
and conveyance of the Leases, Rents, Proceeds and other rents, income, proceeds
and benefits of the Collateral contained in the Granting Clause of this Mortgage
shall constitute an absolute, present and irrevocable assignment, grant and
conveyance, provided, however, that permission is hereby given to the Mortgagor,
so long as no Event of Default has occurred and be continuing hereunder, to
collect, receive and apply such Rents, Proceeds and other rents, income,
proceeds and benefits as they become due and payable, but not further in advance
thereof than is customary, and in accordance with all of the other terms,
conditions and provisions hereof, of the Loan Documents, and of the Leases,
contracts, agreements and other instruments with respect to which such payments
are made or such other benefits are conferred; provided, further, however, that,
to the extent required by the Credit Agreement all such Leases, Rents, Proceeds
and other rents, income, proceeds and benefits shall be deposited directly into
the Lockbox Accounts. Upon the occurrence and continuance of an Event of
Default, such permission shall terminate immediately and automatically, without
notice to the Mortgagor or any other Person except as required by law, and shall
not be reinstated upon a cure of such Event of Default without the express
written consent of the Mortgagee. Such assignment shall be fully effective
without any further action on the part of the Mortgagor or the Mortgagee and the
Mortgagee shall be entitled, at its option without further order of or
application to the Bankruptcy Court, upon the occurrence and continuance of an
Event of Default hereunder, to collect, receive and apply all Rents, Proceeds
and all other rents, income, proceeds and benefits from the Collateral,
including all right, title and interest of the Mortgagor in any escrowed sums or
deposits or any portion thereof or interest therein, whether or not the
Mortgagee takes possession of the Collateral or any part thereof. The Mortgagor
further grants to the Mortgagee the right, at the Mortgagee's option without
further order of or application to the Bankruptcy Court, upon the occurrence and
continuance of an Event of Default hereunder, to:

                  (a) enter upon and take possession of the Property for the
         purpose of collecting Rents, Proceeds and said rents, income, proceeds
         and other benefits;

                                    I-1-A-9
<PAGE>   14

                  (b) dispossess by the customary summary proceedings any
         tenant, purchaser or other Person defaulting in the payment of any
         amount when and as due and payable, or in the performance of any other
         obligation, under any Lease, contract or other instrument to which said
         Rents, Proceeds or other rents, income, proceeds or benefits relate;

                  (c) let or convey the Collateral or any portion thereof or any
         interest therein; and

                  (d) apply Rents, Proceeds and such rents, income, proceeds and
         other benefits, after the payment of all necessary fees, charges and
         expenses, on account of the Secured Obligations in accordance with
         Section 3.11.

         SECTION 1.15. No Claims Against the Mortgagee. Nothing contained in
this Mortgage shall constitute any consent or request by the Mortgagee, express
or implied, for the performance of any labor or the furnishing of any materials
or other property in respect of the Property or any part thereof, or be
construed to permit the making of any claim against the Mortgagee in respect of
labor or services or the furnishing of any materials or other property or any
claim that any lien based on the performance of such labor or the furnishing of
any such materials or other property is prior to the lien and security interest
of this Mortgage. ALL CONTRACTORS, SUBCONTRACTORS, VENDORS AND OTHER PERSONS
DEALING WITH THE PROPERTY, OR WITH ANY PERSONS INTERESTED THEREIN, ARE HEREBY
REQUIRED TO TAKE NOTICE OF THE PROVISIONS OF THIS SECTION.

         SECTION 1.16. Indemnification. The Mortgagor will protect, indemnify,
save harmless and defend the Mortgagee, the Fixed Assets Lenders, and each of
their respective officers, directors, shareholders, employees, representatives
and agents (collectively, the "Indemnified Parties" and individually, an
"Indemnified Party"), from and against any and all liabilities, obligations,
claims, damages, penalties, causes of action, costs and expenses (including,
without limitation, reasonable attorneys' fees and expenses) imposed upon or
incurred by or asserted against any Indemnified Party by reason of (a) ownership
of an interest in this Mortgage, any other Loan Document or the Property, (b)
any accident, injury to or death of persons or loss of or damage to or loss of
the use of property occurring on or about the Property or any part thereof or
the adjoining sidewalks, curbs, vaults and vault spaces, if any, streets, alleys
or ways, (c) any use, non-use or condition of the Property or any part thereof
or the adjoining sidewalks, curbs, vaults and vault spaces, if any, streets,
alleys or ways, (d) any failure on the part of the Mortgagor to perform or
comply with any of the terms of this Mortgage or any Loan Document, (e)
performance of any labor or services or the furnishing of any materials or other
property in respect of the Collateral or any part thereof made or suffered to be
made by or on behalf of the Mortgagor, (f) any negligence or tortious act on the
part of the Mortgagor or any of its agents, contractors, lessees, licensees or
invitees, (g) any work in connection with any alterations, changes, new
construction or demolition of or additions to the Property, or (h) (i) any
Hazardous Material on, in, under or affecting all or any portion of the
Property, the groundwater, or any surrounding areas, (ii) any misrepresentation,
inaccuracy or breach of any warranty, covenant or agreement contained or
referred to in Sections 1.21 and 1.22, (iii) any violation or claim of violation
by the Mortgagor of any Environmental Laws, or (iv) the imposition of any lien
for damages caused by or the recovery of any costs for the cleanup, release or
threatened release of

                                    I-1-A-10
<PAGE>   15

any Hazardous Material, except to the extent that any of the matters described
in subsections (a)-(h) arise out of the gross negligence or willful misconduct
of any Indemnified Party. If any action or proceeding be commenced, to which
action or proceeding any Indemnified Party is made a party by reason of the
execution of this Mortgage or any other Loan Document, or in which it becomes
necessary to defend or uphold the lien of this Mortgage, all sums paid by the
Indemnified Parties, for the expense of any litigation to prosecute or defend
the rights and lien created hereby or otherwise, shall be paid by the Mortgagor
to such Indemnified Parties, as the case may be, as hereinafter provided. The
Mortgagor will pay and save the Indemnified Parties harmless against any and all
liability with respect to any intangible personal property tax or similar
imposition of the State or any subdivision or authority thereof now or hereafter
in effect, to the extent that the same may be payable by the Indemnified Parties
in respect of this Mortgage, any Loan Document or any Secured Obligation. All
amounts payable to the Indemnified Parties under this Section 1.16 shall be
deemed indebtedness secured by this Mortgage and any such amounts which are not
paid within ten (10) days after written demand therefor by any Indemnified Party
shall bear interest at the rate provided for in Section 3.2.2 of the Credit
Agreement from the date of such demand. In case any action, suit or proceeding
is brought against any Indemnified Party by reason of any such occurrence, the
Mortgagor, upon request of such Indemnified Party, will, at the Mortgagor's
expense, resist and defend such action, suit or proceeding or cause the same to
be resisted or defended by counsel designated by the Mortgagor and approved by
such Indemnified Party. The obligations of the Mortgagor under this Section 1.16
shall survive any discharge or reconveyance of this Mortgage and payment in full
of the Secured Obligations.

         SECTION 1.17. No Credit for Payment of Taxes. The Mortgagor shall not
be entitled to any credit against the Secured Obligations by reason of the
payment of any tax on the Property or any part thereof or by reason of the
payment of any other Imposition, and shall not apply for or claim any deduction
from the taxable value of the Property or any part thereof by reason of this
Mortgage.

         SECTION 1.18. Intentionally Omitted.

         SECTION 1.19. No Transfer of the Property. Except as is provided in the
Credit Agreement, and except for the Permitted Encumbrances, the Mortgagor shall
not, without the prior written consent of the Mortgagee, which consent may be
granted or withheld in the sole and absolute discretion of the Mortgagee (i)
sell, convey, assign or otherwise transfer the Property or any portion of the
Mortgagor's interest therein or (ii) further encumber the Property or permit the
Property to become encumbered by any lien, claim, security interest or other
indebtedness of any kind or nature other than the Permitted Encumbrances.

         SECTION 1.20. Security Agreement. With respect to the items of personal
property and fixtures referred to and described in the Granting Clause of this
Mortgage and included as part of the Collateral, this Mortgage is hereby made
and declared to be a security agreement encumbering each and every item of
personal property and fixtures now or hereafter owned by Mortgagor and included
herein as a part of the Collateral, in compliance with the provisions of the
Uniform Commercial Code as enacted in the State. In this respect, Mortgagor, as
"Debtor", expressly grants to Mortgagee, as "Secured Party", a security interest
in and to all of the property now or hereafter owned by Mortgagor which
constitutes the personal property and fixtures

                                    I-1-A-11
<PAGE>   16

hereinabove referred to and described in this Mortgage, including all
extensions, accessions, additions, improvements, betterments, renewals,
replacements and substitutions thereof or thereto, and all proceeds from the
sale or other disposition thereof. Mortgagor agrees that Mortgagee may file this
Mortgage, or a reproduction thereof, in the real estate records or other
appropriate index, as, and this Mortgage shall be deemed to be, a financing
statement filed as a fixture filing in accordance with the laws of the State.
Any reproduction of this Mortgage or of any other security agreement or
financing statement executed by Mortgagor shall be sufficient as a financing
statement. In addition, Mortgagor agrees to execute and deliver to Mortgagee,
upon Mortgagee's request, any other security agreement and financing statements,
as well as extensions, renewals, and amendments thereof, and reproductions of
this Mortgage, in such form as Mortgagee may reasonably require to perfect a
security interest with respect to said items. Mortgagor shall pay all costs of
filing such financing statements and any extensions, renewals, amendments and
releases thereof, and shall pay all reasonable costs and expenses of any record
searches for financing statements Mortgagee may reasonably require. Except as is
provided in the Credit Agreement, and except for the Permitted Encumbrances,
without the prior written consent of Mortgagee, Mortgagor shall not create or
suffer to be created pursuant to the Uniform Commercial Code any other security
interest in the above-described personal property and fixtures, including any
replacements and additions thereto. Upon the occurrence and continuance of an
Event of Default under this Mortgage, the Mortgagee shall have and shall be
entitled to exercise any and all of the rights and remedies (i) as prescribed in
this Mortgage, or (ii) as prescribed by general law, or (iii) as prescribed by
the specific statutory provisions now or hereafter enacted and specified in said
Uniform Commercial Code, all at Mortgagee's sole election. Mortgagor and
Mortgagee agree that the filing of any financing statements in the records
normally having to do with personal property shall not in any way affect the
agreement of Mortgagor and Mortgagee that everything located in, on or about, or
used or intended to be used with or in connection with the use, operation or
enjoyment of, the Collateral, which is described or reflected as a fixture in
this Mortgage, is, and at all times and for all purposes and in all proceedings,
both legal and equitable, shall be, regarded as part of the Real Estate conveyed
hereby. Mortgagor warrants that Mortgagor's name, identity and address are as
set forth herein. The mailing address of the Mortgagee from which information
may be obtained concerning the security interest created herein is also set
forth herein. This information hereof is provided in order that this Mortgage
shall comply with the requirements of the Uniform Commercial Code as enacted in
the State for instruments to be filed as financing statements. In accordance
with the laws of the State, this Mortgage shall remain effective as a fixture
filing until this Mortgage is released or satisfied of record or its
effectiveness otherwise terminates as to the Collateral.

         SECTION 1.21. Representations and Warranties. In order to induce the
Mortgagee to enter into this Mortgage, the Credit Agreement and the other Loan
Documents, the Mortgagor agrees that all of the representations and warranties
set forth in the Credit Agreement are incorporated into this Mortgage by
reference as if fully set forth herein.

         SECTION 1.22. Mortgagor's Covenants. In order to induce the Mortgagee
to enter into this Mortgage, the Credit Agreement and the other Loan Documents,
the Mortgagor agrees that all of the covenants of Mortgagor set forth in the
Credit Agreement are incorporated into this Mortgage by reference as if fully
set forth herein.

<PAGE>   17

         SECTION 1.23. Attornment. Mortgagee hereby acknowledges and agrees that
the liens granted herein are subject to the rights of certain lessees under the
Leases as disclosed in the Credit Agreement and will be subject to the rights of
lessees under any Leases entered into by Mortgagor after the date hereof which
are permitted as Permitted Real Estate Liens pursuant to the Credit Agreement,
subject to the express rights contained in the applicable Lease. The rights of
the tenants under the Leases to the leased premises shall not be adversely
affected by the exercise by Mortgagee of any of its rights hereunder, nor shall
any such tenant be in any way deprived of its rights under the applicable Lease
except in accordance with the terms of such Lease. In the event that Mortgagee
succeeds to the interest of Mortgagor under a Lease, such Lease shall not be
terminated or affected thereby except as set forth therein, and any sale of the
applicable leased premises by Mortgagee or pursuant to the judgment of any court
in an action to enforce the remedies provided for in this Mortgage shall be made
subject to such Lease and the rights of such tenant expressly set forth
thereunder. If Mortgagee succeeds to the interests of Mortgagor in and to the
applicable leased premises or under such Lease or enters into possession of such
leased premises, the Mortgagee, and such tenants, shall be bound to each other
under all of the express terms, covenants and conditions of such Lease, as if
the Mortgagee was originally the Mortgagor as lessor thereunder.

with a limit of not less than Ten Million Dollars ($10,000,000) for each
occurrence, (f) all-risk, builders' risk insurance with respect to the Property

Property in such amounts and against such insurable hazards as the Mortgagee
from time to time may reasonably require by written notice to the Mortgagor.

         SECTION 2.1.2. Policy Provisions. All insurance maintained by the

any named insured, (ii) the occupation or use of the Property for purposes more
hazardous than permitted by the terms thereof, (iii) any foreclosure or other
action or proceeding taken by the Mortgagee pursuant to any provision of this
Mortgage, or (iv) any change in title or ownership of the Property, (e) provide
that no cancellation, reduction in amount or material change in coverage thereof
or any portion thereof shall be effective until at least thirty (30) days after
receipt by the Mortgagee of written notice thereof, (f) provide that any notice
under such policies shall be simultaneously delivered to the Mortgagee, and (g)
be satisfactory in all other reasonable respects to the Mortgagee. Any insurance
maintained pursuant to this Section 2.1 may be evidenced by blanket insurance
policies covering the Property and other properties or assets of the Mortgagor,
provided that any such policy shall specify the portion, if less than all, of
the total coverage of such policy that is allocated to the Property and shall in
all other respects comply with the requirements of this Section 2.1.

         SECTION 2.1.3. Delivery of Policies, etc. The Mortgagor will deliver to
the Mortgagee, promptly upon request, (a) certificates of all policies
evidencing all insurance required to be maintained under Section 2.1.1 (or, in
the case of blanket policies, certificates thereof by the insurers together with
a counterpart of each blanket policy), and (b) evidence as to the payment of all
premiums due thereon (with respect to public liability insurance policies, all
installments for the current year due thereon to such date), provided that the
Mortgagee shall not be deemed by reason of its custody of such certificates to
have knowledge of the contents thereof or of the applicable policies. The
Mortgagor will also deliver to the Mortgagee prior to the expiration of any
policy a binder or certificate of the insurer evidencing the replacement thereof
and when the new policy is issued a certificate of such new policy (or, in the
case of a replacement blanket policy, a certificate thereof of the insurer
together with a counterpart of the blanket policy). In the event the Mortgagor
shall fail to effect or maintain any insurance required to be effected or
maintained pursuant to the provisions of this Section 2.1, the Mortgagor will
indemnify the

                                    I-1-A-14
<PAGE>   19

Mortgagee against damage, loss or liability resulting from all risks for which
such insurance should have been effected or maintained.

         SECTION 2.1.4. Separate Insurance. The Mortgagor will not take out
separate insurance concurrent in form or contributing in the event of loss with
that required to be maintained pursuant to this Section 2.1.

         SECTION 2.2. Damage, Destruction or Taking; Mortgagor to Give Notice;
Assignment of Awards. In case of:

                  (a) any material damage to or destruction of the Collateral or
         any material part thereof, or

                  (b) any taking, whether for permanent or temporary use, of all
         or any material part of the Collateral or any material interest therein
         or material right accruing thereto, as the result of the exercise of
         the right of condemnation or eminent domain, or a change of grade
         affecting the Collateral or any portion thereof (a "Taking"), or the
         commencement of any proceedings or negotiations which may result in a
         Taking,

the Mortgagor will promptly give written notice thereof to the Mortgagee,
generally describing the nature and extent of such damage or destruction and the
Mortgagor's best estimate of the cost of restoring the Collateral, or the nature
of such proceedings or negotiations and the nature and extent of the Taking
which might result therefrom, as the case may be. The Mortgagee shall be
entitled to all insurance proceeds payable on account of such damage or
destruction and to all awards or payments allocable to the Collateral on account
of such Taking up to the amount of the Secured Obligations, and the Mortgagor
hereby irrevocably assigns, transfers and sets over to the Mortgagee all rights
of the Mortgagor to any such proceeds, awards or payments and irrevocably
authorizes and empowers the Mortgagee, at its option, in the name of the
Mortgagor or otherwise, to file and prosecute what would otherwise be the
Mortgagor's claim for any such proceeds, award or payment and to collect,
receipt for and retain the same for disposition in accordance with Section 2.3.
The Mortgagor will pay all reasonable costs and expenses incurred by the
Mortgagee in connection with any such damage, destruction or Taking and seeking
and obtaining any insurance proceeds, awards or payments in respect thereof.

         SECTION 2.3. Application of Proceeds and Awards. Subject to any
applicable requirements of the Financing Order, the Credit Agreement and the
Revolver Intercreditor Agreement, all amounts recovered under any insurance
policy required to be maintained by the Mortgagor hereunder and all awards
received by it on account of any Taking shall be deposited in a Lockbox Account
maintained by the Mortgagor to be applied pursuant to the provisions of the
Credit Agreement.

         Notwithstanding the foregoing provisions of this Section 2.3 to the
contrary (but subject to the provisions of Section 2.4), and if each of the
following conditions is satisfied, the Mortgagee, upon request of the Mortgagor,
may apply up toward $2,500,000 of insurance proceeds or condemnation awards
received by it to the restoration or replacement of the affected Collateral, to
the extent necessary for the restoration or replacement thereof; provided, that:

                                    I-1-A-15
<PAGE>   20

                           (i) no Default or Event of Default then exists;

                           (ii) the Mortgagor shall have furnished to the
                  Mortgagee a certificate of an architect or engineer reasonably
                  acceptable to the Mortgagee stating (x) that the affected
                  Collateral is capable of being restored, prior to the maturity
                  of the Credit Agreement, to substantially the same condition
                  as existed prior to the casualty, (y) the aggregate estimated
                  direct and indirect costs of such restoration and (z) as to
                  any Taking, that the property taken in such Taking, or sold
                  under threat thereof, is not necessary to the Mortgagor's
                  customary use or occupancy of the Property or Mortgagor
                  otherwise provides Mortgagee adequate assurance that the
                  Collateral can be restored; and

                           (iii) in the event that the estimated cost of
                  restoration set forth in the certificate of such architect or
                  engineer (and such revisions to such estimate as are from time
                  to time made) exceeds maximum amount of insurance proceeds or
                  condemnation awards that would be permitted to be applied to
                  the restoration or replacement of the Collateral pursuant to
                  the foregoing, the Mortgagor shall deposit the amount of such
                  excess with the Mortgagee.

         In the event that, after the restoration or replacement of the
Collateral, any insurance or condemnation awards shall remain, such amount shall
be deposited in a Lockbox Account to be applied pursuant to the provisions of
the Credit Agreement. If, prior to the receipt by the Mortgagee of such
insurance proceeds or condemnation awards, the Collateral shall have been sold
on foreclosure, the Mortgagee shall have the right to receive said insurance
proceeds or condemnation awards to the extent of any deficiency found to be due
upon such sale, with legal interest thereon, whether or not a deficiency
judgment shall have been sought or recovered or denied, and the reasonable
attorneys' fees, costs and disbursements incurred by the Mortgagee in connection
with the collection of such award or payment.

         SECTION 2.4. Total Taking and Total Destruction. Subject to any
applicable requirements of the Financing Order, the Credit Agreement and the
Revolver Intercreditor Agreement, in the event of a Total Destruction or a Total
Taking, the Mortgagee shall apply all amounts recovered under any insurance
policy referred to in Section 2.1.1 and all awards received by it on account of
any such Taking shall be deposited in a Lockbox Account maintained by the
Mortgagor to be applied pursuant to the provisions of the Credit Agreement.

                        EVENTS OF DEFAULT; REMEDIES, ETC.

         SECTION 3.1. Events of Default; Acceleration. If an "Event of Default"
(pursuant to and as defined in the Credit Agreement) shall have occurred and be
continuing, then and in any such event the Mortgagee may, subject to any
applicable requirements of the Financing Order, the Credit Agreement and the
Revolver Intercreditor Agreement, at any time thereafter (unless all Events of
Default shall theretofore have been remedied and all costs and expenses,
including, without limitation, attorneys' fees and expenses incurred by or on
behalf of the Mortgagee, shall have been paid in full by the Mortgagor) declare,
by written notice to the Mortgagor, the Fixed Assets Loans and all other Secured
Obligations to be due and payable immediately or on a date specified in such
notice, and on such date the same shall be and become due and payable, together
with interest accrued thereon, without presentment, demand, protest or notice,
all of which the Mortgagor hereby waives. The Mortgagor will pay on demand all
costs and expenses, including, without limitation, attorneys' fees and expenses,
incurred by or on behalf of the Mortgagee in enforcing this Mortgage, or any
other Loan Document evidencing or securing the Fixed Assets Loans, or occasioned
by any default hereunder or thereunder.

         SECTION 3.2. Legal Proceedings; Judicial Foreclosure. If an Event of
Default shall have occurred and be continuing, the Mortgagee at any time may, at
its election and without further order of or application to the Bankruptcy
Court, but subject to any applicable requirements of the Financing Order, the
Credit Agreement and the Revolver Intercreditor Agreement, proceed at law or in
equity or otherwise to enforce the payment and performance of the Secured
Obligations in accordance with the terms hereof and thereof and to foreclose the
lien of this Mortgage as against all or any part of the Collateral and to have
the same sold under the judgment or decree of a court of competent jurisdiction.
The Mortgagee shall be entitled to recover in such proceedings all costs
incident thereto, including attorneys' fees and expenses in such amounts as may
be fixed by the court.

         SECTION 3.3. Power of Sale. If an Event of Default shall have occurred
and be continuing, the Mortgagee may, without further order of or application to
the Bankruptcy Court, but subject to any applicable requirements of the
Financing Order, the Credit Agreement and the Revolver Intercreditor Agreement,
grant, bargain, sell, assign, transfer, convey and deliver the whole or, from
time to time, any part of the Collateral, or any interest in any part thereof,
at any private sale or at public auction, with or without demand, advertisement
or notice, for cash, on credit or for other property, for immediate or future
delivery, and for such price or prices and on such terms as the Mortgagee in its
sole discretion may determine, or as may be required by law, and upon such sale
the Mortgagee may execute and deliver to the purchaser(s) instruments of
conveyance pursuant to the terms hereof and to applicable laws. Without limiting
the authority granted in this Section 3.3, the Mortgagee shall, without further
order of or application to the Bankruptcy Court and without demand on the
Mortgagor, but subject to any applicable requirements of the Financing Order,
the Credit Agreement and the Revolver Intercreditor Agreement, after the lapse
of such time as may then be required by law, and notice of default and notice of
sale having been given as then required by law, sell the Collateral on the date
and at the time and place designated in the notice of sale, either as a whole or
in separate parcels and in

                                    I-1-A-17
<PAGE>   22

such order as the Mortgagee may determine, but subject to any statutory right of
the Mortgagor to direct the order in which such property, if consisting of
several known lots, parcels or interests, shall be sold, at public auction to
the highest bidder, the purchase price payable in lawful money of the United
States at the time of sale. The Person conducting the sale may, for any cause
deemed expedient, postpone the sale from time to time until it shall be
completed and, in every such case, notice of postponement shall be given by
public declaration thereof by such Person at the time and place last appointed
for the sale; provided that, if the sale is postponed for longer than one (1)
day beyond the day designated in the notice of sale, notice of sale and notice
of the time, date and place of sale shall be given in the same manner as the
original notice of sale. The Mortgagee shall execute and deliver to the
purchaser at any such sale a mortgagee's deed conveying the property so sold,
but without any covenant or warranty, express or implied. The recitals in such
mortgagee's deed of any matters or facts shall be conclusive proof of the
truthfulness thereof. Any Person, including the Mortgagee, may bid at the sale.

         SECTION 3.4. Uniform Commercial Code Remedies. If an Event of Default
shall have occurred and be continuing, the Mortgagee may, without further order
of or application to the Bankruptcy Court, but subject to any applicable
requirements of the Financing Order, the Credit Agreement and the Revolver
Intercreditor Agreement, exercise from time to time and at any time any rights
and remedies available to it under applicable law upon default in the payment of
indebtedness, including, without limitation, any right or remedy available to it
as a secured party under the Uniform Commercial Code of the State. The Mortgagor
shall, promptly upon request by the Mortgagee, assemble the Collateral, or any
portion thereof generally described in such request, and make it available to
the Mortgagee at such place or places designated by the Mortgagee and reasonably
convenient to the Mortgagee or the Mortgagor. If the Mortgagee elects to proceed
under the Uniform Commercial Code of the State to dispose of portions of the
Collateral, the Mortgagee, at its option, may give the Mortgagor notice of the
time and place of any public sale of any such property, or of the date after
which any private sale or other disposition thereof is to be made, by sending
notice by registered or certified first class mail, postage prepaid, to the
Mortgagor at least ten (10) days before the time of the sale or other
disposition. If any notice of any proposed sale, assignment or transfer by the
Mortgagee of any portion of the Collateral or any interest therein is required
by law, the Mortgagor conclusively agrees that ten (10) days notice to the
Mortgagor of the date, time and place (and, in the case of a private sale, the
terms) thereof is reasonable.

         SECTION 3.5. Mortgagee Authorized to Execute Deeds, etc. The Mortgagor
irrevocably appoints the Mortgagee (which appointment is coupled with an
interest) the true and lawful attorney of the Mortgagor, in its name and stead
and on its behalf, for the purpose of effectuating any sale, assignment,
transfer or delivery for the enforcement hereof, whether pursuant to power of
sale, foreclosure or otherwise, to execute and deliver all such deeds, bills of
sale, assignments, releases and other instruments as may be designated in any
such request.

         SECTION 3.6. Purchase of Collateral by Mortgagee. The Mortgagee may be
a purchaser of the Collateral or of any part thereof or of any interest therein
at any sale thereof, whether pursuant to power of sale, foreclosure or
otherwise, and the Mortgagee may apply upon the purchase price thereof the
indebtedness secured hereby owing to the Mortgagee. Such purchaser shall, upon
any such purchase, acquire good title to the properties so purchased, free of

                                    I-1-A-18
<PAGE>   23

the security interest and lien of this Mortgage and free of all rights of
redemption in the Mortgagor.

         SECTION 3.7. Receipt a Sufficient Discharge to Purchaser. Upon any sale
of the Collateral or any part thereof or any interest therein, whether pursuant
to power of sale, foreclosure or otherwise, the receipt of the Mortgagee or the
officer making the sale under judicial proceedings shall be a sufficient
discharge to the purchaser for the purchase money, and such purchaser shall not
be obliged to see to the application thereof.

         SECTION 3.8 Waiver of Appraisement, Valuation, etc. The Mortgagor
hereby waives, to the fullest extent it may lawfully do so, the benefit of all
appraisement, valuation, stay, extension and redemption laws now or hereafter in
force and all rights of marshaling in the event of any sale of the Collateral or
any part thereof or any interest therein.

         SECTION 3.9. Sale a Bar Against Mortgagor. Any sale of the Collateral
or any part thereof or any interest therein under or by virtue of this Mortgage,
whether pursuant to power of sale, foreclosure or otherwise, shall forever be a
bar against the Mortgagor.

         SECTION 3.10. Secured Obligations to Become Due on Sale. Except as
otherwise provided in the Credit Agreement, upon any sale of the Collateral or
any portion thereof or interest therein by virtue of the exercise of any remedy
by the Mortgagee under or by virtue of this Mortgage, whether pursuant to power
of sale, foreclosure or otherwise in accordance with this Mortgage or by virtue
of any other remedy available at law or in equity or by statute or otherwise, at
the option of the Mortgagee, any sums or monies due and payable pursuant to the
Credit Agreement pertaining to the Fixed Assets Loans, the Loan Documents
pertaining to the Fixed Assets Loans and in connection with the Fixed Assets
Loans and/or the Secured Obligations shall, if not previously declared due and
payable, immediately become due and payable, together with interest accrued
thereon, and all other indebtedness which this Mortgage by its terms secures.

         SECTION 3.11. Application of Proceeds of Sale and Other Moneys. Subject
to any applicable requirements of the Financing Order, the Credit Agreement and
the Revolver Intercreditor Agreement, the proceeds of any sale of the Collateral
or any part thereof or any interest therein under or by virtue of this Mortgage,
whether pursuant to power of sale, foreclosure or otherwise, and all other
moneys at any time held by the Mortgagee as part of the Collateral, shall be
applied in such order of priority as the Mortgagee shall determine in its sole
and absolute discretion including, without limitation, as follows:

                  (a) first, to the payment of the reasonable costs and expenses
         of such sale (including, without limitation, the cost of evidence of
         title and the costs and expenses, if any, of taking possession of,
         retaining custody over, repairing, managing, operating, maintaining and
         preserving the Collateral or any part thereof prior to such sale), all
         reasonable costs and expenses incurred by the Mortgagee or any other
         Person in obtaining or collecting any insurance proceeds, condemnation
         awards or other amounts received by the Mortgagee, all reasonable costs
         and expenses of any receiver of the Collateral or any part thereof, and
         any Impositions or other charges or expenses prior to

                                    I-1-A-19
<PAGE>   24

         the security interest or lien of this Mortgage, which the Mortgagee may
         consider it necessary or desirable to pay;

                  (b) second, to the payment of any Secured Obligation (other
         than those set forth in Section 3.11 (c) below);

                  (c) third, to the payment of all amounts of principal of and
         interest (including Post-Petition Interest to the extent such interest
         is a Secured Obligation) at the time due and payable under the Credit
         Agreement pertaining to the Fixed Assets Loans at the time outstanding
         (whether due by reason of maturity or by reason of any prepayment
         requirement or by declaration or acceleration or otherwise), including
         interest at the rate provided for in the Credit Agreement on any
         overdue principal and (to the extent permitted under applicable law) on
         any overdue interest; and, in case such moneys shall be insufficient to
         pay in full such principal and interest, then, first, to the payment of
         all amounts of interest (including Post-Petition Interest to the extent
         such interest is a Secured Obligation) at the time due and payable and,
         second, to the payment of all amounts of principal at the time due and
         payable under the Fixed Assets Loans; and

                  (d) fourth, the balance, if any, held by the Mortgagee after
         payment in full of all amounts referred to in subdivisions Sections
         3.11(a), (b) and (c) above, shall, unless a court of competent
         jurisdiction may otherwise direct by final order not subject to appeal,
         be paid to or upon the direction of the Mortgagor.

         SECTION 3.12. Appointment of Receiver. If an Event of Default shall
have occurred and be continuing, the Mortgagee shall, as a matter of right,
without notice, and without regard to the adequacy of any security for the
indebtedness secured hereby or the solvency of the Mortgagor, be entitled to,
without further order of or application to the Bankruptcy Court, but subject to
any applicable requirements of the Financing Order, the Credit Agreement and the
Revolver Intercreditor Agreement, the appointment of a receiver for all or any
part of the Collateral, whether such receivership be incidental to a proposed
sale of the Collateral or otherwise, and the Mortgagor hereby consents to the
appointment of such a receiver and will not oppose any such appointment.

         SECTION 3.13. Possession. Management and Income. If an Event of Default
shall have occurred and be continuing, in addition to, and not in limitation of,
the rights and remedies provided in Section 1.14, the Mortgagee, upon five (5)
days written notice to the Mortgagor, may, without further order of or
application to the Bankruptcy Court, but subject to any applicable requirements
of the Financing Order, the Credit Agreement and the Revolver Intercreditor
Agreement, enter upon and take possession of the Collateral or any part thereof
by force, summary proceeding, ejectment or otherwise and may remove the
Mortgagor and all other Persons and any and all property therefrom and may hold,
operate, maintain, repair, preserve and manage the same and receive all
earnings, income, Rents, issues and Proceeds accruing with respect thereto or
any part thereof. The Mortgagee shall be under no liability for or by reason of
any such taking of possession, entry, removal or holding, operation or
management, except that any amounts so received by the Mortgagee shall be
applied to pay all costs and expenses of so entering upon, taking possession of,
holding, operating, maintaining, repairing, preserving and managing the
Collateral or any part thereof, and any Impositions or other charges prior to
the

                                    I-1-A-20
<PAGE>   25

lien and security interest of this Mortgage which the Mortgagee may consider it
necessary or desirable to pay, and any balance of such amounts shall be applied
as provided in Section 3.11.

         SECTION 3.14. Right of Mortgagee to Perform Mortgagor's Covenants, etc.
If the Mortgagor shall fail to make any payment or perform any act required to
be made or performed hereunder or under the Credit Agreement pertaining to the
Fixed Assets Loans or any other Loan Document pertaining to the Fixed Assets
Loans, the Mortgagee, without further order of or application to the Bankruptcy
Court, without notice to or demand upon the Mortgagor and without waiving or
releasing any obligation or Event of Default, may (but shall be under no
obligation to) at any time thereafter make such payment or perform such act for
the account and at the expense of the Mortgagor, and may enter upon the
Collateral for such purpose and take all such action thereon as, in the
Mortgagee's opinion, may be necessary or appropriate therefor. No such entry and
no such action shall be deemed an eviction of any lessee of the Property or any
part thereof. All sums so paid by the Mortgagee and all costs and expenses
(including, without limitation, attorneys' fees and expenses) so incurred,
together with interest thereon at the rate provided for in Section 3.2.2 of the
Credit Agreement from the date of payment or incurring, shall constitute
additional indebtedness under the Credit Agreement secured by this Mortgage and
shall be paid by the Mortgagor to the Mortgagee on demand.

         SECTION 3.15. Subrogation. To the extent that the Mortgagee, on or
after the date hereof, pays any sum due under any provision of any Legal
Requirement or any instrument creating any lien prior or superior to the lien of
this Mortgage, or the Mortgagor or any other Person pays any such sum with the
proceeds of the Fixed Assets Loans, the Mortgagee shall have and be entitled to
a lien on the Collateral equal in priority to the lien discharged, and the
Mortgagee shall be subrogated to, and receive and enjoy all rights and liens
possessed, held or enjoyed by, the holder of such lien, which shall remain in
existence and benefit the Mortgagee in securing the Secured Obligations.

         SECTION 3.16. Remedies, etc., Cumulative. Each right, power and remedy
of the Mortgagee provided for in this Mortgage, the Credit Agreement pertaining
to the Fixed Assets Loans or any other Loan Document pertaining to the Fixed
Assets Loans, or now or hereafter existing at law or in equity or by statute or
otherwise shall be cumulative and concurrent and shall be in addition to every
other right, power or remedy provided for in this Mortgage, the Credit Agreement
or any other Loan Document pertaining to the Fixed Assets Loans, or now or
hereafter existing at law or in equity or by statute or otherwise, and the
exercise or beginning of the exercise by the Mortgagee of any one or more of the
rights, powers or remedies provided for in this Mortgage, the Credit Agreement,
or any other Loan Document pertaining to the Fixed Assets Loans, or now or
hereafter existing at law or in equity or by statute or otherwise shall not
preclude the simultaneous or later exercise by the Mortgagee of any or all such
other rights, powers or remedies.

         SECTION 3.17. Provisions Subject to Applicable Law. All rights, powers
and remedies provided in this Mortgage may be exercised only to the extent that
the exercise thereof does not violate any applicable provisions of law and are
intended to be limited to the extent necessary so that they will not render this
Mortgage invalid, unenforceable or not entitled to be recorded, registered or
filed under the provisions of any applicable law. If any term of this Mortgage
or any

                                    I-1-A-21
<PAGE>   26

application thereof shall be invalid or unenforceable, the remainder of this
Mortgage and any other application of such term shall not be affected thereby.

         SECTION 3.18. No Waiver, etc. No failure by the Mortgagee to insist
upon the strict performance of any term hereof or of the Credit Agreement, or of
any other Loan Document, or to exercise any right, power or remedy consequent
upon a breach hereof or thereof, shall constitute a waiver of any such term or
of any such breach. No waiver of any breach shall affect or alter this Mortgage,
which shall continue in full force and effect with respect to any other then
existing or subsequent breach. By accepting payment or performance of any amount
or other Secured Obligations secured hereby before or after its due date, the
Mortgagee shall not be deemed to have waived its right either to require prompt
payment or performance when due of all other amounts and Secured Obligations
payable hereunder or to declare a default for failure to effect such prompt
payment.

         SECTION 3.19. Compromise of Actions, etc. Any action, suit or
proceeding brought by the Mortgagee pursuant to any of the terms of this
Mortgage, the Credit Agreement pertaining to the Fixed Assets Loans, any other
Loan Document pertaining to the Fixed Assets Loans, or otherwise, and any claim
made by the Mortgagee hereunder or thereunder, may be compromised, withdrawn or
otherwise dealt with by the Mortgagee without any notice to or approval of the
Mortgagor.

         MORTGAGOR HEREBY EXPRESSLY AND IRREVOCABLY SUBMITS TO THE NON-EXCLUSIVE
         JURISDICTION OF ALL FEDERAL AND STATE COURTS LOCATED IN THE STATE AND

         MAIL OR BY PERSONAL SERVICE WITHIN OR WITHOUT THE STATE IN

                                    I-1-A-26
<PAGE>   31

         ACCORDANCE WITH APPLICABLE LAW, PROVIDED A REASONABLE TIME FOR
         APPEARANCE IS ALLOWED. THE MORTGAGOR AND MORTGAGEE EACH EXPRESSLY
         WAIVES, TO THE EXTENT IT MAY LAWFULLY DO SO, ANY OBJECTION, CLAIM OR
         DEFENSE WHICH IT MAY HAVE AT ANY TIME TO THE LAYING OF VENUE OF ANY
         ACTION, SUIT OR PROCEEDING ARISING OUT OF THIS MORTGAGE, THE CREDIT
         AGREEMENT OR ANY OTHER LOAN DOCUMENT PERTAINING TO THE FIXED LOANS IN
         ANY SUCH COURT, IRREVOCABLY WAIVES ANY CLAIM THAT ANY SUCH SUIT, ACTION
         OR PROCEEDING BROUGHT IN ANY SUCH COURT HAS BEEN BROUGHT IN AN

         WITH RESPECT TO ANY SUCH CLAIM, SUIT, ACTION OR PROCEEDING BROUGHT IN
         ANY SUCH COURT, THAT SUCH COURT DOES NOT HAVE JURISDICTION OVER THE
         PERSON OF THE MORTGAGOR. NOTHING CONTAINED HEREIN WILL BE DEEMED TO
         PRECLUDE THE MORTGAGEE FROM BRINGING AN ACTION AGAINST THE MORTGAGOR IN
         ANY OTHER JURISDICTION.

         SECTION 5.12. Severability; Conflicts. Any provision of this Mortgage,
the Credit Agreement or any other Loan Document pertaining to the Fixed Assets
Loans which is prohibited or unenforceable in any jurisdiction shall as to such
provision and such jurisdiction, be ineffective to the extent of such
prohibition or unenforceability without invalidating the remaining provisions of
this Mortgage, the Credit Agreement or such Loan Document pertaining to the
Fixed Assets Loans or affecting the validity or enforceability of such provision
in any other jurisdiction. In the event of any conflict between the terms of
this Mortgage and the terms of the Credit Agreement, the terms of the Credit
Agreement shall control.

         SECTION 5.13. Loan Document. This Mortgage is a Loan Document executed
pursuant to the Credit Agreement and, unless otherwise expressly indicated
herein, shall be construed, administered and applied in accordance with the
terms and provisions thereof.

         SECTION 5.14. Usury Savings Clause. It is the intention of the
Mortgagor and the Mortgagee to conform strictly to the usury laws governing the
Loan Documents pertaining to the Fixed Assets Loans, and any interest payable
under the Loan Documents pertaining to the Fixed Assets Loans shall be subject
to reduction to the amount not in excess of the maximum non-usurious amount
allowed under such laws, as construed by the courts having jurisdiction over
such matters. In the event the maturity of the Secured Obligations is
accelerated by reason of any provision of the Loan Documents pertaining to the
Fixed Assets Loans, or by reason of an election by the Mortgagee resulting from
an Event of Default, then earned interest may never include more than the
maximum amount permitted by law, computed from the dates of each advance of loan
proceeds under the Credit Agreement until payment, and any interest in excess of
the maximum amount permitted by law shall be canceled automatically or, if
theretofore paid, at the option of the Mortgagee, shall be rebated to the
Mortgagor, or shall be credited on the principal amount of the Secured
Obligations or, if all principal has been repaid, then the excess shall be
rebated to the Mortgagor. If any interest is canceled, credited against
principal or rebated to the Mortgagor in accordance with the foregoing sentence
and, if thereafter the interest payable hereunder is less than the maximum
amount permitted by applicable law, the rate

                                    I-1-A-27
<PAGE>   32

hereunder shall automatically be increased to the maximum extent possible to
permit repayment to the Mortgagee and the Lenders as soon as possible of any
interest in excess of the maximum amount permitted by law which was earlier
canceled, credited against principal or rebated to the Mortgagor pursuant to the
provisions of the foregoing sentence.

         SECTION 5.15. Future Advances. This Mortgage is a "Future Advance
Mortgage" under the laws of the State. Any and all future advances under this
Mortgage and the Loan Documents pertaining to the Fixed Assets Loans shall have
the same priority as if the future advance was made on the date that this
Mortgage was recorded. This Mortgage shall secure the Secured Obligations,
whenever incurred, such Secured Obligations to be due at the times provided in
the Loan Documents pertaining to the Fixed Assets Loans. Notice is hereby given
that the Secured Obligations may increase as a result of any defaults hereunder
by Mortgagor due to, for example, and without limitation, unpaid interest or
late charges, unpaid taxes or insurance premiums which the Mortgagee elects to
advance, defaults under leases that the Mortgagee elects to cure, attorney fees
or costs incurred in enforcing the Loan Documents pertaining to the Fixed Assets
Loans or other expenses incurred by the Mortgagee in protecting the Collateral,
the security of this Mortgage or the Mortgagee's rights and interests.

         SECTION 5.16. Mortgage Subject to Revolver Intercreditor Agreement.
Notwithstanding anything to the contrary contained herein, it is expressly
understood and agreed by the parties hereto that this Mortgage shall be subject
to the terms of the Revolver Intercreditor Agreement.
