          (b)  Landlord shall have the right at any time following the

cause the Leased Premises and any other Person occupying any part of the Leased
Premises to comply with and conform to, all Insurance Requirements and Legal
Requirements (including all applicable Environmental Laws). Tenant shall not at
any time (i) cause, permit or suffer to occur any Environmental Violation or
(ii) permit any sublessee, assignee or other Person occupying the Leased
Premises under or through Tenant to cause, permit or suffer to occur any
Environmental Violation and, at the request of Landlord or Lender, Tenant shall
promptly remediate or undertake any other appropriate response action to correct
any existing Environmental Violation, however immaterial. Any and all reports
prepared for or by Landlord with respect to the Leased Premises shall be for the
sole benefit of Landlord and Lender and no other Person shall have the right to
rely on any such reports. Notwithstanding the foregoing, Tenant shall have the
right, at Tenant's sole cost and expense, to contest any covenants enforceable
against Tenant by any third parties provided that the Lease shall remain in full
force and effect.

          (b)  Tenant, at its sole cost and expense, will at all times promptly
and faithfully abide by, discharge and perform all of the covenants, conditions
and agreements contained in any Easement Agreement on the part of Landlord or
the occupier to be kept and performed thereunder. Subject to Paragraph 35
hereof, Tenant will not alter, modify, amend or terminate any Easement
Agreement, give any consent or approval thereunder, or enter into any new
Easement Agreement without, in each case, the prior written consent of Landlord,
such consent not to be unreasonably withheld or delayed.

          (c)  Upon prior written notice from Landlord, Tenant shall permit such
persons as Landlord may designate ("Site Reviewers") to visit the Leased
                                    --------------
Premises and perform, as agents of Tenant, in a manner which does not
unreasonably interfere with Tenant's business, environmental site
investigations and assessments ("Site Assessments") on the Leased Premises for
                                 ----------------
the purpose of determining whether there exists on the Leased Premises any
Environmental Violation or any condition which could result in any Environ-
mental Violation. Such Site Assessments may include both above and below the
ground testing for Environmental Violations and such other tests as may be
necessary, in the opinion of the Site Reviewers, to conduct the Site
Assessments. Any such investigations, assessments and testing should be
performed in a good and workmanlike manner in compliance with all applicable
Legal Requirements and in a manner which does not unreasonably interfere with
Tenant's business on the Leased Premises. Tenant shall supply to the Site
Reviewers such historical and operational information regarding the Leased
Premises as may be reasonably requested by the Site Reviewers to facilitate the
Site Assessments, and shall make available for meetings with the Site Reviewers
appropriate

                                      12
<PAGE>

personnel having knowledge of such matters. The cost of performing and reporting
any Site Assessments shall be paid by Tenant.

          (d)  If an Environmental Violation occurs or is found to exist and, in
Landlord's reasonable judgment, the cost of remediation of, or other response
action with respect to, the same is likely to exceed $500,000, Tenant shall
provide to Landlord, within ten (10) days after Landlord's request therefor,
adequate financial assurances that Tenant will effect such remediation in
accordance with applicable Environmental Laws. Such financial assurances shall
be a bond or letter of credit reasonably satisfactory to Landlord in form and
substance and in an amount equal to or greater than Landlord's reasonable
estimate, based upon a Site Assessment performed pursuant to Paragraph 10(c),
of the anticipated cost of such remedial action.

          (e)  Notwithstanding any other provision of this Lease, if an
Environmental Violation occurs or is found to exist and the Term would otherwise
terminate or expire and either (1) as a result of the Environmental Violation
the Landlord, after good faith efforts is unable to lease the Leased Premises at
its fair market rental value absent such Environmental Violation or (2) the
Environmental Violation causes a diminution in the value of the Premises, then,
at the option of Landlord, the Term shall be automatically extended beyond the
date of termination or expiration and this Lease shall remain in full force and
effect beyond such date until the earlier to occur of (i) the completion of all
remedial action in accordance with applicable Environmental Laws or (ii) the
date specified in a written notice from Landlord to Tenant terminating this
Lease.

          (f)  If Tenant fails to correct any Environmental Violation which
occurs or is found to exist, Landlord shall have the right (but no obligation)
to take any and all actions as Landlord shall deem necessary or advisable in
order to cure such Environmental Violation.

          (g)  Tenant shall notify Landlord immediately after becoming aware of
any Environmental Violation (or alleged Environmental Violation) or
noncompliance with any of the covenants contained in this Paragraph 10 and shall
forward to Landlord immediately upon receipt thereof copies of all orders,
reports, notices, permits, applications or other communications relating to any
such violation or noncompliance.

          (h)  All future leases, subleases or concession agreements relating to
the Leased Premises entered into by Tenant shall contain covenants of the other
party not to at any time (i) cause any Environmental Violation to occur or (ii)

Lender if and to the extent that any Mortgage so provides.

consent of Landlord and Lender. Subject to the provisions of this Paragraph
17(b), Tenant hereby irrevocably assigns to Landlord any award or payment to
which Tenant is or may be entitled by reason of any Condemnation, whether the

business, if available, to the extent that and so long as (i) Tenant shall have
the right to make, and does make, a separate claim therefor against the
condemnor and (ii) such claim does not in any way reduce either the amount of
the award otherwise payable to Landlord for the Condemnation of Landlord's fee

rights of Landlord under this Paragraph 17(b) shall also be extended to Lender

          (c)  If any Partial Casualty (whether or not insured against) or
Partial Condemnation shall occur, this Lease shall continue, notwithstanding

Obligations. Promptly after such Partial Casualty or Partial Condemnation,
Tenant, as required in Paragraphs 12(a) and 13(b), shall commence and diligently
continue to restore the Leased Premises as nearly as possible to their value,
condition and character immediately prior to such event (assuming the Leased
Premises to have been in the condition required by this Lease). So long as no
Event of Default exists, any Net Award up to and including $250,000 shall be
paid by Landlord to Tenant and Tenant shall restore the Leased Premises in
accordance with the requirements of Paragraphs 12(a) and 13(b) of this Lease.

Net Award is a Termination Event) be made available by Landlord (or Lender, if
required by the terms of any Mortgage) to Tenant for the restoration of any of
the Leased Premises pursuant to and in accordance with the provisions of

therein and a certified resolution of the Board of Directors of Tenant
authorizing the same. Promptly upon the delivery to Landlord of a Termination
Notice, Landlord and Tenant shall commence to determine the Fair Market Value.

          (c)  If Landlord shall reject such offer to terminate this Lease
pursuant to Paragraph 18(b) above by written notice to Tenant (a "Rejection"),
                                                                  ---------
which Rejection shall contain the written consent of Lender, not later than
thirty (30) days following the Fair Market Value Date, then this Lease shall
terminate on the Termination Date; provided that, if Tenant has not satisfied
all Monetary Obligations and all other obligations and liabilities under this
Lease which have arisen on or prior to the Termination Date (collectively,
"Remaining Obligations") on the Termination Date, then Landlord may, at its
 ---------------------
option, extend the date on which this Lease may terminate to a date which is no
later than the first Basic Rent Payment Date after the Termination Date on which
Tenant has satisfied all Remaining Obligations. Upon such termination (i) all
obligations of Tenant hereunder shall terminate except for any Surviving
Obligations, (ii) Tenant shall immediately vacate and shall have no further
right, title or interest in or to any of the Leased Premises and (iii) the Net
Award shall be retained by Landlord. Notwithstanding anything to the contrary
hereinabove contained, if Tenant shall have received a Rejection and, on the
date when this Lease would otherwise terminate as provided above, Landlord shall
not have received the full amount of the Net Award payable by reason of the
applicable Termination Event, then the date on which this Lease is to terminate
automatically shall be extended to the first Basic Rent Payment Date after the
receipt by Landlord of the full amount of the Net Award provided that, if Tenant
has not satisfied all Remaining Obligations on such date, then Landlord may, at
its option, extend the date on which this Lease may terminate to a date which is
no later than the first Basic Rent Payment Date after such date on which Tenant
has satisfied all such Remaining Obligations.

          (d)  Unless Tenant shall have received a Rejection not later than
the thirtieth (30th) day following the Fair Market Value Date, Landlord shall be
conclusively presumed to have accepted such offer. If such offer is accepted by
Landlord then, on the Termination Date, Tenant shall pay to Landlord the
Termination Amount and all Remaining Obligations and, if requested by Tenant,
Landlord shall (i) convey to Tenant the Leased Premises or the remaining portion
thereof, if any, and (ii) pay to or assign to Tenant Landlord's entire interest
in and to the Net Award, all in accordance with Paragraph 20.

      19. Restoration.
          -----------

          (a)  Landlord (or Lender if required by any Mortgage) shall hold Net
Award in excess of $250,000 in a fund (the "Restoration Fund") and disburse
                                            ----------------
amounts from the Restoration Fund only in accordance with the following
conditions:

               (i)    prior to commencement of restoration, (A) the architects,
contracts, contractors, plans and specifications for the restoration shall have
been approved by Landlord, such approval not to be unreasonably withheld or
delayed, (B) Landlord and Lender shall be provided with mechanics' lien
insurance (if available) and acceptable performance and payment bonds which
insure satisfactory completion of and payment for the restoration, are in an

                                      21
<PAGE>

amount and form and have a surety acceptable to Landlord, and name Landlord and
Lender as additional dual obligees;

               (ii)   at the time of any disbursement, no Event of Default shall
exist and no mechanics' or materialmen's liens shall have been filed against any
of the Leased Premises and remain undischarged or unbonded unless the title
company insuring Landlord's title is willing to insure over such lien;

               (iii)  disbursements shall be made from time to time in an amount
not exceeding the cost of the work completed since the last disbursement, upon
receipt of (A) satisfactory evidence, including architects' certificates, of the
stage of completion, the estimated total cost of completion and performance of
the work to date in a good and workmanlike manner in accordance with the
contracts, plans and specifications, (B) waivers of liens, (C) contractors' and
subcontractors' sworn statements as to completed work and the cost thereof for
which payment is requested, (D) a satisfactory bringdown of title insurance and
(E) other evidence of cost and payment so that Landlord can verify that the
amounts disbursed from time to time are represented by work that is completed,
in place and free and clear of mechanics' and materialmen's lien claims;

               (iv)   each request for disbursement shall be accompanied by a
certificate of Tenant, signed by an authorized officer of Tenant, describing the
work for which payment is requested, stating the cost incurred in connection
therewith, stating that Tenant has not previously received payment for such work
and, upon completion of the work, also stating that the work has been fully
completed and complies with the applicable requirements of this Lease;

               (v)    Landlord may retain ten percent (10%) of the Restoration
Fund until the restoration is fully completed;

               (vi)   if the Restoration Fund is held by Landlord, the
Restoration Fund shall not be commingled with Landlord's other funds and shall
bear interest at a rate agreed to by Landlord and Tenant; and

               (vii)  such other reasonable conditions as Landlord or Lender
may impose.

          (b)  Prior to commencement of restoration and at any time during
restoration, if the estimated cost of completing the restoration work free and
clear of all liens, as determined by Landlord, exceeds the amount of the Net
Award available for such restoration, the amount of such excess shall, upon
demand by Landlord, be paid by Tenant to Landlord to be added to the Restoration
Fund. Any sum so added by Tenant which remains in the Restoration Fund upon
completion of restoration shall be refunded to Tenant. For purposes of
determining the source of funds with respect to the disposition of funds
remaining after the completion of restoration, the Net Award shall be deemed to
be disbursed prior to any amount added by Tenant.

          (c)  If any sum remains in the Restoration Fund after completion of
the restoration and any refund to Tenant pursuant to Paragraph 19(b), such sum
shall be retained by Landlord or, if required by a Note or Mortgage, paid by
Landlord to a Lender.

     20.  Procedures Upon Purchase.
          ------------------------

          (a)  If the Leased Premises is purchased by Tenant pursuant to any
provision of this Lease, Landlord need not convey any better title thereto than
that which was conveyed to Landlord, and Tenant shall accept such title,
subject, however, to the Permitted

                                      22
<PAGE>

Encumbrances and to all other liens, exceptions and restrictions on, against or
relating to any of the Leased Premises and to all applicable Laws, but free of
the lien of and security interest created by any Mortgage or Assignment and
liens, exceptions and restrictions on, against or relating to the Leased
Premises which have been created by or resulted solely from acts of Landlord
after the date of this Lease, unless the same are Permitted Encumbrances or
customary utility easements benefiting the Leased Premises or were created with
the concurrence of Tenant or as a result of a default by Tenant under this
Lease.

          (b)  Upon the date fixed for any such purchase of the Leased Premises
pursuant to any provision of this Lease (any such date the "Purchase Date"),
                                                            -------------
Tenant shall pay to Landlord, or to any Person to whom Landlord directs payment,
the Relevant Amount therefor specified herein, in Federal Funds, less any credit
of the Net Award received and retained by Landlord or a Lender allowed against
the Relevant Amount, and Landlord shall deliver to Tenant (i) a special warranty
deed which describes the premises being conveyed and conveys the title thereto
as provided in Paragraph 20(a), (ii) such other instruments as shall be
necessary to transfer to Tenant or its designee any other property (or rights to
any Net Award not yet received by Landlord or a Lender) then required to be sold
by Landlord to Tenant pursuant to this Lease and (iii) any Net Award received by
Landlord, not credited to Tenant against the Relevant Amount and required to be
delivered by Landlord to Tenant pursuant to this Lease; provided, that if any
Monetary Obligations remain outstanding on such date, then Landlord may deduct
from the Net Award the amount of such Monetary Obligations; and further
provided, that if any event has occurred which, in Landlord's reasonable
judgment, is likely to subject any Indemnitee to any liability which Tenant is
required to indemnify against pursuant to Paragraph 15, then an amount shall be
deducted from the Net Award which, in Landlord's reasonable judgment, is
sufficient to satisfy such liability, which amount shall be deposited in an
interest-bearing escrow account for the benefit of Tenant with a financial
institution reasonably satisfactory to Landlord and Tenant pending resolution of
such matter. If on the Purchase Date any Monetary Obligations remain outstanding
and no Net Award is payable to Tenant by Landlord or the amount of such Net
Award is less than the amount of the Monetary Obligations, then Tenant shall pay
to Landlord on the Purchase Date the amount of such Monetary Obligations. Upon
the completion of such purchase, this Lease and all obligations and liabilities
of Tenant hereunder shall terminate, except any Surviving Obligations.

          (c)  If the completion of such purchase shall be delayed after (i)
the Termination Date, in the event of a purchase pursuant to Paragraph 18 or,
(ii) the date scheduled for such purchase, in the event of a purchase under any
other provision of this Lease then (x) Rent shall continue to be due and payable
until completion of such purchase if such purchase is delayed for more than six
(6) months after the date scheduled for such purchase and (y) at Landlord's sole
option, Fair Market Value shall be redetermined and the Relevant Amount payable
by Tenant pursuant to the applicable provision of this Lease shall be adjusted
to reflect such redetermination.

          (d)  Any prepaid Monetary Obligations paid to Landlord shall be
prorated as of the Purchase Date, and the prorated unapplied balance shall be
deducted from the Relevant Amount due to Landlord; provided, that no
apportionment of any Impositions shall be made upon any such purchase.

     21.  Assignment and Subletting; Prohibition against Leasehold Financing.
          -------------------------------------------------------------------

          (a)  (i) Tenant shall have the right, upon thirty (30) days prior
written notice to Landlord and Lender, with no consent of Landlord or Lender
being required or necessary ("Preapproved Assignment") to assign this Lease by
                              ----------------------
operation of law or otherwise to any Person ("Preapproved Assignee") that
                                              --------------------
immediately following such assignment will have a publicly traded unsecured
senior debt rating of "Baal" or better from Moody's Investors

                                      23
<PAGE>

Services, Inc. or a rating of "BBB+" or better from Standard & Poor's
Corporation, and in the event all of such rating agencies cease to furnish such
ratings, then a comparable rating by any rating agency reasonably acceptable to
Landlord and Lender.

               (ii)   If Tenant desires to assign this Lease, whether by
operation of law or otherwise, to a Person ("Non-Preapproved Assignee") who
                                             ------------------------
would not be a Preapproved Assignee ("Non-Preapproved Assignment") then Tenant
                                      --------------------------
shall, not less than ninety (90) days prior to the date on which it desires to
make a Non-Preapproved Assignment submit to Landlord and Lender information
regarding the following with respect to the Non-Preapproved Assignee
(collectively, the "Review Criteria"): (A) credit, (B) capital structure, (C)
                    ---------------
management, (D) operating history, (E) proposed use of the Leased Premises and
(F) risk factors associated with the proposed use of the Leased Premises by the
Non-Preapproved Assignee, taking into account factors such as environmental
concerns, product liability and the like. Landlord and Lender shall review such
information and shall approve or disapprove the Non-Preapproved Assignee no
later than the thirtieth (30th) day following receipt of all such information,
and Landlord and Lender shall be deemed to have acted reasonably in granting or
withholding consent if such grant or disapproval is based on their review of the
Review Criteria applying prudent business judgment.

          (b)  (i) Tenant shall have the right, upon thirty (30) days prior
written notice to Landlord and Lender, to enter into one or more subleases that
demise, in the aggregate, up to but not in excess of ten percent (10%) of the
gross space in the Improvements with no consent or approval of Landlord being
required or necessary ("Preapproved Sublet"). Other than pursuant to
                        ------------------
Preapproved Sublets, at no time during the Term shall subleases for more than
ten percent (10%) of the gross space in the Leased without the prior written
consent of Landlord which consent shall be granted or withheld based on a review
of the Review Criteria as they relate to the proposes sublessee and the terms of
the proposed sublease. Landlord and Lender shall be deemed to have acted
reasonably in granting or withholding consent if such grant or disapproval is
based on their review of the Review Criteria using prudent business judgment.

          (c)  If Tenant assigns all its rights and interest under this Lease,
the assignee under such assignment shall expressly assume all the obligations of
Tenant hereunder, actual or contingent, including obligations of Tenant which
may have arisen on or prior to the date of such assignment, by a written
instrument delivered to Landlord at the time of such assignment. Each sublease
of any of the Leased Premises shall be subject and subordinate to the provisions
of this Lease. No assignment or sublease shall affect or reduce any of the
obligations of Tenant hereunder, and all such obligations shall continue in full
force and effect as obligations of a principal and not as obligations of a
guarantor, as if no assignment or sublease had been made. No assignment or
sublease shall impose any additional obligations on Landlord under this Lease.

          (d)  Tenant shall, within ten (10) days after the execution and
delivery of any assignment or sublease consented to by Landlord, deliver a
duplicate original copy thereof to Landlord which, in the event of an
assignment, shall be in recordable form.

          (e)  As security for performance of its obligations under this Lease,
Tenant hereby grants, conveys and assigns to Landlord all right, title and
interest of Tenant in and to all subleases now in existence or hereafter entered
into for any or all of the Leased Premises, any and all extensions,
modifications and renewals thereof and all rents, issues and profits therefrom.
Landlord hereby grants to Tenant a license to collect and enjoy all rents and
other sums of money payable under any sublease of any of the Leased Premises,
provided, however, that Landlord shall have the absolute right to revoke said
license and to collect such rents and sums of money and to retain the same with
all such amounts being applied against any Monetary Obligation otherwise payable
by Tenant. Tenant shall not consent to, cause or allow any modification or
alteration of any of the terms, conditions or covenants of any of the

                                      24
<PAGE>

subleases or the termination thereof, without the prior written approval of
Landlord, which consent shall not be unreasonably withheld, nor shall Tenant
accept any rents more than thirty (30) days in advance of the accrual thereof
nor do nor permit anything to be done, the doing of which, nor omit or refrain
from doing anything, the omission of which, will or could be a breach of or
default in the terms of any of the subleases.

          (f)  Tenant shall not have the power to mortgage, pledge or otherwise
encumber its interest under this Lease or any sublease of the Leased Premises,
and any such mortgage, pledge or encumbrance made in violation of this Paragraph
21 shall be void and of no force and effect. Notwithstanding the foregoing, in
the event Tenant pledges or encumbers any of its personal property and/or
equipment to any lender, Landlord, at the request of such lender, shall enter
into a lien waiver agreement with such lender in form reasonably satisfactory to
Landlord.

          (g)  Landlord may sell or transfer the Leased Premises at any time
without Tenant's consent to any third party (each a "Third Party Purchaser").
                                                     ----------------------
In the event of any such transfer, Tenant shall attorn to any Third Party
Purchaser as Landlord so long as such Third Party Purchaser and Landlord notify
Tenant in writing of such transfer and such Third Party Purchaser shall assume
all of the obligations of Landlord under this Lease. At the request of Landlord,
Tenant will execute such documents confirming the agreement referred to above
and such other agreements as Landlord may reasonably request, provided that such
agreements do not increase the liabilities and obligations of Tenant hereunder.

     22.  Events of Default.
          -----------------

          (a)  The occurrence of any one or more of the following (after
expiration of any applicable cure period as provided in Paragraph 22(b)) shall,
at the sole option of Landlord, constitute an "Event of Default" under this
Lease:

               (i)    a failure by Tenant to make any payment of any Monetary
Obligation, regardless of the reason for such failure;

               (ii)   a failure by Tenant duly to perform and observe, or a
violation or breach of, any other provision hereof not otherwise specifically
mentioned in this Paragraph 22(a);

any certificate, demand or request made pursuant hereto proves to be incorrect,
now or hereafter, in any material respect;

               (iv)   a default beyond any applicable cure period or at maturity
by Tenant in any payment of principal or interest on any obligations for
borrowed money having an original principal balance of $500,000 or more in the
aggregate, or in the performance of any other provision contained in any
instrument under which any such obligation is created or secured (including the
breach of any covenant thereunder), (x) if such payment is a payment at maturity
or a final payment, or (y) if an effect of such default is to cause such
obligation to become due prior to its stated maturity;

               (v)    a default by Tenant beyond any applicable cure period in
the payment of rent under, or in the performance of any other material provision
of, any other lease or leases that have, in the aggregate, rental obligations
over the terms thereof of $500,000 or more;

                                      25
<PAGE>

               (vi)   a final, non-appealable judgment or judgments for the
payment of money in excess of $500,000 in the aggregate shall be rendered
against Tenant and the same shall remain undischarged for a period of sixty (60)
consecutive days unless Tenant's insurance carrier advises Landlord in writing
that it is obligated to pay such judgment or judgments;

               (vii)  The breach of any Covenant shall occur;

               (viii) Tenant shall (A) voluntarily be adjudicated a bankrupt or
insolvent, (B) seek or consent to the appointment of a receiver or trustee for
itself or for the Leased Premises, (C) file a petition seeking relief under the
bankruptcy or other similar laws of the United States, any state or any
jurisdiction, (D) make a general assignment for the benefit of creditors, or (E)
be unable to pay its debts as they mature;

               (ix)   a court shall enter an order, judgment or decree
appointing, without the consent of Tenant, a receiver or trustee for it or for
any of the Leased Premises or approving a petition filed against Tenant which
seeks relief under the bankruptcy or other similar laws of the United States,
any state or any jurisdiction, and such order, judgment or decree shall remain
undischarged or unstayed ninety (90) days after it is entered;

               (x)    the Leased Premises shall have been vacated or abandoned;

               (xi)   Tenant shall be liquidated or dissolved or shall begin
proceedings towards its total or substantial liquidation or towards dissolution;

               (xii)  the estate or interest of Tenant in any of the Leased
Premises shall be levied upon or attached in any proceeding and such estate or
interest is about to be sold or transferred or such process shall not be vacated
or discharged within sixty (60) days after it is made;

               (xiii) a failure by Tenant to perform or observe, or a violation
or breach of, or a misrepresentation by Tenant under any provision of any
Assignment or any other document between Tenant and Lender, if such failure,
violation, breach or misrepresentation gives rise to a default beyond any
applicable cure period with respect to any Loan;

               (xiv)  a failure by Tenant to maintain in effect any other
license or permit necessary for the use, occupancy or operation of the Leased
Premises.

          (b)  No notice or cure period shall be required in any one or more of
the following events: (A) the occurrence of an Event of Default under clause (i)
(except as otherwise set forth below), (iii), (iv), (v), (vi), (vii), (viii),
(ix), (x), (xi), (xii), (xiii) or (xiv) of Paragraph 22(a); (B) the default
consists of a failure to pay Basic Rent, a failure to provide any insurance
required by Paragraph 16 or an assignment or sublease entered into in violation
of Paragraph 21; or (C) the default is such that any delay in the exercise of a
remedy by Landlord could reasonably be expected to cause irreparable harm to
Landlord. If the default consists of the failure to pay any Basic Rent under
clause (i) of Paragraph 22(a), the applicable cure period shall be three (3)
days from the date on which notice is given, but Landlord shall not be obligated
to give notice of, or allow any cure period for, any such default more than one
(1) time within any Lease Year. If the default consists of the failure to pay
any Monetary Obligation under clause (i) of Paragraph 22(a) other than Basic
Rent, the applicable cure period shall be three (3) days from the date on which
notice is given, but Landlord shall not be obligated to give notice of, or allow
any cure period for, any such default more than three (3) times within any Lease
Year. If the default consists of a default under clause (ii) of Paragraph 22(a),
other than the events specified in clauses (B) and (C) of the first sentence of
this Paragraph 22(b), the applicable cure period shall

                                      26
<PAGE>

be thirty (30) days from the date on which notice is given, or, if the default
cannot be cured within such thirty (30) day period, or such longer cure period
as provided to Landlord by Lender, and delay in the exercise of a remedy would
not (in Landlord's reasonable judgment) cause any material adverse harm to
Landlord or any of the Leased Premises, the cure period shall be extended for
the period required to cure the default (but such cure period, including any
extension, shall not in the aggregate exceed such period as is provided to
Landlord by Lender), provided that Tenant shall commence to cure the default
within the said thirty-day period, and shall actively, diligently and in good
faith proceed with and continue the curing of the default until it shall be
fully cured.

     23.  Remedies and Damages Upon Default.
          ---------------------------------

          (a)  If an Event of Default shall have occurred and is continuing,
Landlord shall have the right, at its sole option, then or at any time
thereafter, to exercise its remedies and to collect damages from Tenant in
accordance with this Paragraph 23, subject in all events to applicable Law,
without demand upon or notice to Tenant except as otherwise provided in
Paragraph 22(b) and this Paragraph 23.

               (i)    Landlord may give Tenant notice of Landlord's intention to
terminate this Lease on a date specified in such notice. Upon such date, this
Lease, the estate hereby granted and all rights of Tenant hereunder shall expire
and terminate. Upon such termination, Tenant shall immediately surrender and
deliver possession of the Leased Premises to Landlord in accordance with
Paragraph 26. If Tenant does not so surrender and deliver possession of the
Leased Premises, Landlord may re-enter and repossess the Leased Premises, upon
obtaining a judicial order to such effect or by summary proceedings, ejectment
or any other lawful means or procedure through order of a court of competent
jurisdiction. Upon or at any time after taking possession of the Leased
Premises, Landlord may, by peaceable means or legal judicial process, remove any
Persons or property therefrom. Landlord shall be under no liability for or by
reason of any such entry, repossession or removal. Notwithstanding such entry or
repossession, Landlord, may (A) exercise the remedy set forth in and collect the
damages permitted by Paragraph 23(a)(iii) or (B) collect the damages set forth
in Paragraph 23(b)(i) or 23(b)(ii).

               (ii)   After repossession of the Leased Premises pursuant to
clause (i) above, Landlord shall have the right to relet any of the Leased
Premises to such tenant or tenants, for such term or terms, for such rent, on
such conditions and for such uses as Landlord in its sole discretion may
determine, and collect and receive any rents payable by reason of such
reletting. Landlord may make such Alterations in connection with such reletting
as it may deem advisable in its sole discretion. Notwithstanding any such
reletting, Landlord may collect the damages set forth in Paragraph 23(b)(ii).

               (iii)  Landlord may, upon notice to Tenant, require Tenant to
make an irrevocable offer to terminate this Lease upon payment to Landlord of an
amount (the "Default Termination Amount") specified in the next sentence. The
             --------------------------
"Default Termination Amount" shall be the greatest of (A) the Fair Market Value
of the Leased Premises, (B) the sum of the Acquisition Cost and Prepayment
Premium which Landlord will be required to pay in prepaying any Loan with
proceeds of the Default Termination Amount or (C) an amount equal to the Present
Value of the entire Basic Rent from the date of such purchase to the date on
which the Term would expire, assuming that the Term has been extended for all
extension periods, if any, provided for in this Lease. Upon such notice to
Tenant, Tenant shall be deemed to have made such offer and shall, if requested
by Landlord, within ten (10) days following such request deposit with Landlord
as payment against the Default Termination Amount the amount described in (B)
above and Landlord and Tenant shall promptly commence to determine Fair Market
Value. Within thirty (30) days after the Fair Market Value Date, Landlord shall
accept or reject

                                      27
<PAGE>

such offer. If Landlord accepts such offer then, on the tenth (1Oth) business
day after such acceptance, Tenant shall pay to Landlord the Default Termination
Amount and, at the request of Tenant, Landlord will convey the Leased Premises
to Tenant or its designee in accordance with Paragraph 20. Any rejection by
Landlord of such offer shall have no effect on any other remedy Landlord may
have under this Lease.

               (iv)   Landlord may declare by notice to Tenant the entire Basic
Rent (in the amount of Basic Rent then in effect) for the remainder of the then
current Term to be immediately due and payable. Tenant shall immediately pay to
Landlord all such Basic Rent discounted to its Present Value, all accrued Rent
then due and unpaid, all other Monetary Obligations which are then due and
unpaid and all Monetary Obligations which arise or become due by reason of such
Event of Default (including any Costs of Landlord). Upon receipt by Landlord of
all such accelerated Basic Rent and Monetary Obligations, this Lease shall
remain in full force and effect and Tenant shall have the right to possession of
the Leased Premises from the date of such receipt by Landlord to the end of the
Term, and subject to all the provisions of this Lease, including the obligation
to pay all increases in Basic Rent and all Monetary Obligations that
subsequently become due, except that (A) no Basic Rent which has been prepaid
hereunder shall be due thereafter during the said Term, and (B) Tenant shall
have no option to extend or renew the Term.

          (b)  The following constitute damages to which Landlord shall be
entitled if Landlord exercises its remedies under Paragraph 23(a)(i) or
23(a)(ii):

               (i)    If Landlord exercises its remedy under Paragraph 23(a)(i)
but not its remedy under Paragraph 23(a)(ii) (or attempts to exercise such
remedy and is unsuccessful in reletting the Leased Premises) then, upon written
demand from Landlord, Tenant shall pay to Landlord, as liquidated and agreed
final damages for Tenant's default and in lieu of all current damages beyond the
date of such demand (it being agreed that it would be impracticable or extremely
difficult to fix the actual damages), an amount equal to the Present Value of
the excess, if any, of (A) all Basic Rent from the date of such demand to the
date on which the Term is scheduled to expire hereunder in the absence of any
earlier termination, re-entry or repossession over (B) the then fair market
rental value of the Leased Premises for the same period. Tenant shall also pay
to Landlord all of Landlord's Costs in connection with the repossession of the
Leased Premises and any attempted reletting thereof, including all brokerage
commissions, reasonable legal expenses, attorneys' fees, employees' expenses,
costs of Alterations and expenses and preparation for reletting, including the
installation of a sprinkler system for office use.

               (ii)   If Landlord exercises its remedy under Paragraph 23(a)(i)
or its remedies under Paragraph 23(a)(i) and 23(a)(ii), then Tenant shall, until
the end of what would have been the Term in the absence of the termination of
the Lease, and whether or not any of the Leased Premises shall have been relet,
be liable to Landlord for, and shall pay to Landlord, as liquidated and agreed
current damages all Monetary Obligations which would be payable under this Lease
by Tenant in the absence of such termination less the net proceeds, if any, of
any reletting pursuant to Paragraph 23(a)(ii), after deducting from such
proceeds all of Landlord's Costs (including the items listed in the last
sentence of Paragraph 23(b)(i) hereof) incurred in connection with such
repossessing and reletting; provided, that if Landlord has not relet the Leased
Premises, such Costs of Landlord shall be considered to be Monetary Obligations
payable by Tenant. Tenant shall be and remain liable for all sums aforesaid, and
Landlord may recover such damages from Tenant and institute and maintain
successive actions or legal proceedings against Tenant for the recovery of such
damages. Nothing herein contained shall be deemed to require Landlord to wait to
begin such action or other legal proceedings until the date when the Term would
have expired by its own terms had there been no such Event of Default.

          (c)  Notwithstanding anything to the contrary herein contained, in
lieu of or in addition to any of the foregoing remedies and damages, Landlord
may exercise any remedies and collect any damages available to it at law or in
equity. If Landlord is unable to obtain full satisfaction pursuant to the
exercise of any remedy, it may pursue any other remedy which it has hereunder or
at law or in equity.

          (d)  Landlord shall not be required to mitigate any of its damages
hereunder unless required to by applicable Law. If any Law shall validly limit
the amount of any damages provided for herein to an amount which is less than
the amount agreed to herein, Landlord shall be entitled to the maximum amount
available under such Law.

          (e)  No termination of this Lease, repossession or reletting of the
Leased Premises, exercise of any remedy or collection of any damages pursuant to
this Paragraph 23 shall relieve Tenant of any Surviving Obligations.

          (f)  WITH RESPECT TO ANY REMEDY OR PROCEEDING OF LANDLORD HEREUNDER,
LANDLORD AND TENANT WAIVES ANY RIGHT TO A TRIAL BY JURY.

          (g)  Upon the occurrence of any Event of Default, Landlord shall
have the right (but no obligation) to perform any act required of Tenant
hereunder and, if performance of such act requires that Landlord enter the
Leased Premises, Landlord may enter the Leased Premises for such purpose.

          (h)  No failure of Landlord (i) to insist at any time upon the
strict performance of any provision of this Lease or (ii) to exercise any
option, right, power or remedy contained in this Lease shall be construed as a
waiver, modification or relinquishment thereof. A receipt by Landlord of any sum
in satisfaction of any Monetary Obligation with knowledge of the breach of any
provision hereof shall not be deemed a waiver of such breach, and no waiver by
Landlord of any provision hereof shall be deemed to have been made unless
expressed in a writing signed by Landlord.

          (i)  Tenant hereby waives and surrenders, for itself and all those
claiming under it, including creditors of all kinds, (i) any right and privilege
which it or any of them may have under any present or future Law to redeem any
of the Leased Premises or to have a continuance of this Lease after termination
of this Lease or of Tenant's right of occupancy or possession pursuant to any
court order or any provision hereof, and (ii) the benefits of any present or
future Law which exempts property from liability for debt or for distress for
rent.

          (j)  Except as otherwise provided herein, all remedies are cumulative
and concurrent and no remedy is exclusive of any other remedy. Each remedy may
be exercised at any time an Event of Default has occurred and is continuing and
may be exercised from time to time. No remedy shall be exhausted by any exercise
thereof.

          (b)  Tenant shall make available to Landlord and to Lender within

     29.  Determination of Value.
          ----------------------

          (a)  Whenever a determination of Fair Market Value is required
pursuant to any provision of this Lease, such Fair Market Value shall be
determined in accordance with the following procedure:

               (i)    Landlord and Tenant (or Third Party Purchaser with respect
to a determination under clause (D) below) shall endeavor to agree upon such
Fair Market Value within thirty (30) days after the date (the "Applicable
                                                               ----------
Initial Date") on which (A) Tenant provides Landlord with notice of its
------------
intention to terminate this Lease and purchase the Leased Premises pursuant to
Paragraph 18, (B) Landlord provides Tenant with notice of its intention to
redetermine Fair Market Value pursuant to Paragraph 20(c), (C) Landlord provides
Tenant with notice of Landlord's intention to require Tenant to make an offer to
terminate this Lease pursuant to Paragraph 23(a)(iii), or (D) Landlord elects to
convey to Tenant the Excess Land under Paragraph 36(a)(iii). Upon reaching such
agreement, the parties shall execute an agreement setting forth the amount of
such Fair Market Value.

               (ii)   If the parties shall not have signed such agreement within
thirty (30) days after the Applicable Initial Date, Landlord and Tenant shall
within fifty (50) days after the Applicable Initial Date each select an
appraiser and notify the other party in writing of the name, address and
qualifications of such appraiser. Such two appraisers shall endeavor to agree
upon Fair Market Value based on a written appraisal made by each of them (and
given to Landlord by Tenant) as of the Relevant Date. If such two appraisers
shall agree upon a Fair Market Value, the amount of such Fair Market Value as so
agreed shall be binding and conclusive upon Landlord and Tenant.

                                      31
<PAGE>

               (iii)  If such two appraisers shall be unable to agree upon a
Fair Market Value within twenty (20) days after the selection of both
appraisers, then such appraisers shall advise Landlord and Tenant of their
respective determination of Fair Market Value and shall select a third appraiser
to make the determination of Fair Market Value. The selection of the third
appraiser shall be binding and conclusive upon Landlord and Tenant.

               (iv)   If such two appraisers shall be unable to agree upon the
designation of a third appraiser within ten (10) days after the expiration of
the twenty (20) day period referred to in clause (iii) above, or if such third
appraiser does not make a determination of Fair Market Value within twenty (20)
days after his selection, then such third appraiser or a substituted third
appraiser, as applicable, shall, at the request of either party hereto, be
appointed by the President or Chairman of the American Arbitration Association
in New York, New York. The determination of Fair Market Value made by the third
appraiser appointed pursuant hereto shall be made within twenty (20) days after
such appointment.

               (v)    If a third appraiser is selected, Fair Market Value shall
be the average of the determination of Fair Market Value made by the third
appraiser and the determination of Fair Market Value made by the appraiser
(selected pursuant to Paragraph 29(a)(ii) hereof) whose determination of Fair
Market Value is nearest to that of the third appraiser. Such average shall be
binding and conclusive upon Landlord and Tenant.

               (vi)   All appraisers selected or appointed pursuant to this
Paragraph 29(a) shall (A) be independent qualified MAI appraisers (B) have no
right, power or authority to alter or modify the provisions of this Lease, (C)
utilize the definition of Fair Market Value hereinabove set forth above, and (D)
be registered in the State if the State provides for or requires such
registration. The Cost of the procedure described in this Paragraph 29(a) above
shall be borne entirely by Tenant.

          (b)  If, by virtue of any delay, Fair Market Value is not determined
by the expiration or termination of the then current Term, then the date on
which the Term would otherwise expire or terminate shall be extended to the date
specified for termination in the particular provision of this Lease pursuant to
which the determination of Fair Market Value is being made.

          (c)  In determining Fair Market Value as defined in clause (b) of the
definition of Fair Market Value, the appraisers shall add (a) the present value
of the Rent for the remaining Term, provided, however, that in the event Fair
Market Value is being determined in accordance with Paragraph 23 the Term shall
be assumed to have been extended for all extension periods provided herein,
(with assumed increases in the CPI to be determined by the appraisers) using a
discount rate (which may be determined by an investment banker retained by each
appraiser) based on the creditworthiness of Tenant and (b) the present value of
the Leased Premises as of the end of such Term, provided, however, that in the
event Fair Market Value is being determined in accordance with Paragraph 23 the
Term shall be assumed to have been extended for all extension periods provided
herein. The appraisers shall further assume that no default then exists under
the Lease, that Tenant has complied (and will comply) with all provisions of the
Lease, and that Tenant has not violated (and will not violate) any of the
Covenants.

     30.  Non-Recourse as to Landlord. Anything contained herein to the contrary
          ---------------------------
notwithstanding, any claim based on or in respect of any liability of Landlord
under this Lease shall be enforced only against the Leased Premises and not
against any other assets, properties or funds of (i) Landlord, (ii) any
director, officer, member, general partner, shareholder, limited partner,
beneficiary, employee or agent of Landlord or any general partner of Landlord or
any of its members or general partners (or any legal representative, heir,
estate, successor or assign of

                                      32
<PAGE>

any thereof), (iii) any predecessor or successor partnership or corporation (or
other entity) of Landlord or any of its general partners, shareholders,
officers, directors, members, employees or agents, either directly or through
Landlord or its general partners, shareholders, officers, directors, employees
or agents or any predecessor or successor partnership or corporation (or other
entity), or (iv) any Person affiliated with any of the foregoing, or any
director, officer, employee or agent of any thereof.

     31.  Financing.
          ---------

          (a)  Tenant agrees to pay all reasonable out-of-pocket costs and
expenses incurred by Landlord in connection with the purchase, leasing and
initial financing of the Leased Premises including, without limitation, the cost
of appraisals, environmental reports, title insurance, transfer and recording
fees and taxes, surveys, legal fees and expenses, Lender's commitment fees and
any "points" charged by Lender which "points" shall not exceed the
amount of $125,000. In no event shall Tenant be obligated to pay costs and
expenses incurred by Landlord in the refinancing of any Loan.

          (b)  Tenant agrees to pay, within ten (10) business days of written
demand therefor, any cost, charge or expense (other than the principal of the
Note and interest thereon at the contract rate of interest specified therein)
imposed upon Landlord by Lender pursuant to the Note, the Mortgage or the
Assignment which is not caused solely by the gross negligence or willful
misconduct of Landlord and which is not otherwise reimbursed by Tenant to
Landlord pursuant to any other provision of this Lease.

          (c)  If Landlord desires to obtain or refinance any Loan, Tenant
shall negotiate in good faith with Landlord concerning any request made by any
Lender or proposed Lender for changes or modifications in this Lease. In
particular, Tenant shall agree, upon request of Landlord, to supply any such
Lender with such notices and information as Tenant is required to give to
Landlord hereunder and to extend the rights of Landlord hereunder to any such
Lender and to consent to such financing if such consent is requested by such
Lender. Tenant shall provide any other consent or statement and shall execute
any and all other documents that such Lender requires in connection with such
financing, including any environmental indemnity agreement and subordination,
non-disturbance and attornment agreement, so long as the same do not in any
material respect adversely affect any right, benefit or privilege of Tenant
under this Lease or in any material respect increase Tenant's obligations under
this Lease. Such subordination, nondisturbance and attornment agreement may
require Tenant to confirm that (a) Lender and its assigns will not be liable for
any misrepresentation, act or omission of Landlord and (b) Lender and its
assigns will not be subject to any counterclaim, demand or offset which Tenant
may have against Landlord.

     32.  Subordination, Non-Disturbance and Attornment. Provided that a
          ----------------------------------------------
suitable non-disturbance agreement is entered into by any Lender, in a form
reasonably acceptable to Tenant, this Lease and Tenant's interest hereunder
shall be subordinate to any Mortgage or other security instrument hereafter
placed upon the Leased Premises by Landlord, and to any and all advances made or
to be made thereunder, to the interest thereon, and all renewals, replacements
and extensions thereof, provided that any such Mortgage or other security
instrument (or a separate instrument in recordable form duly executed by the
holder of any such Mortgage or other security instrument and delivered to
Tenant) shall provide for the recognition of this Lease and all Tenant's rights
hereunder unless and until an Event of Default exists or Landlord shall have the
right to terminate this Lease pursuant to any applicable provision hereof.

     33.  Financial Covenants. Tenants hereby covenants and agrees to comply
          -------------------
with all the covenants and agreements described in Exhibit "E" hereto.
                                                   -----------

          ------------------------
each shall treat this transaction as a true lease for state law purposes and
shall report this transaction as a Lease for Federal income tax purposes. For
Federal income tax purposes each shall report this Lease as a true lease with
Landlord as the owner of the Leased Premises and Equipment and Tenant as the
lessee of such Leased Premises and Equipment including: (1) treating Landlord as
the owner of the property eligible to claim depreciation deductions under
Section 167 or 168 of the Internal Revenue Code of 1986 (the "Code") with
respect to the Leased Premises and Equipment, (2) Tenant reporting its Rent
payments as rent expense under Section 162 of the Code, and (3) Landlord
reporting the Rent payments as rental income.

     35.  Restrictive Covenant Issues. One of the Permitted Encumbrances
          -----------------------------
encumbering the Leased Premises is the Amended and Restated Declaration of
Covenants, Conditions, Restrictions, Easements, Charges and Liens on and for
Lake Forest Addition filed by Forest/Hillcrest Partners dated effective April
16, 1998 (such instrument, as amended from time to time, being the
"Declaration"), which is recorded at Volume 98148, Page 3823 of the Real Estate
Records of Dallas County, Texas. The terms, "Association," "Board," "Class B
Member," "Member," "Office Tract," "Owner," and "OTARC" shall have the same
meanings as are set forth in the Declaration. The parties agree that, so long as
this Lease remains in force and effect:

          (a)  All monetary obligations of Landlord as the Class B Member and
Owner of the Office Tract pursuant to the Declaration shall constitute Monetary
Obligations hereunder and shall be borne by Tenant;

          (b)  Landlord shall upon the execution of this Lease and thereafter
as and when requested by Tenant to do so, give irrevocable instructions to the
Association and the Board that all written notices to which the Class B Member
and Owner of the Office Tract are entitled to receive pursuant to the
Declaration shall be given jointly to Tenant and Landlord. In addition, Landlord
will promptly furnish Tenant with copies of all notices it receives pursuant to
the Declaration;

          (c)  shall have the right: As long as no Event of Default hereunder is
continuing, Tenant

               (i)    to serve as the Class B Member on the Board, as the Class
B Member on the committee known as OTARC, and on all such other committees as
the Class B Member and/or Owner of the Office Tract is entitled to have
representation pursuant to the Declaration,

               (ii)   to vote as the Class B Member in person or by proxy at
meetings of Members, and

               (iii)  to exercise all rights of every nature (including without
limitation voting rights and the rights of approval, consent, review and
inspection) which are accorded to the Class B Member and to Owner of the Office
Tract pursuant to the Declaration.

In furtherance of the foregoing, Landlord hereby grants to Tenant an irrevocable
proxy coupled with an interest to exercise, as long as no Event of Default
hereunder is continuing, all of the rights, powers and remedies of the Class B
Member and Owner of the Office Tract under the Declaration, and the proxy herein
granted shall continue during the Term of this Lease and all renewals; provided,
however, that in no event shall the grant of such proxy and the exercise thereof
by Tenant be deemed, in any way, to modify any of the terms of this Lease.
Landlord shall promptly execute and deliver to Tenant, the Association and/or
the Board such proxies and other designations as Tenant, the Association or the
Board may from time to time request in order to effectuate the foregoing.

     36.  Excess Land.
          ------------

          In the event Tenant desires to construct additional improvements on
the Excess Land, and no Event of Default then exists, Landlord, at its sole
option, (i) shall construct or cause to be constructed such improvements and
lease such improvements to Tenant upon terms and conditions reasonably
satisfactory to Landlord and subject to this Lease or (ii) shall cause the
Excess Land to be released from the terms of this Lease and conveyed to an
affiliate of Landlord who shall construct or cause to be constructed such
improvements and lease such improvements to Tenant upon terms and conditions
reasonably satisfactory to Landlord, or (iii) shall convey the Excess Land to
Tenant for a price ("Excess Land Price") equal to the greater of $2,052,356 plus
                     -----------------
the applicable Prepayment Premium or the sum of the Fair Market Value of the
Excess Land (as Fair Market Value is defined in clause (a) of the definition
thereof) plus the applicable Prepayment Premium provided that the following
conditions are satisfied: (A) the Leased Premises shall have been subdivided in
compliance with all applicable subdivision laws, Legal Requirements and Easement
Agreements so that the Excess Land and the remainder of the Leased Premises (the
"Retained Premises") are separate tracts, (B) after such sale both the Excess
-------------------
Land and the Retained Premises shall comply with all applicable Laws, Legal
Requirements and Easement Agreements, (C) the release of the Excess Land does
not materially impact the functional use, legal use or viability of the Retained
Premises, (D) Tenant shall have complied with all requirements of Lender set
forth in the Mortgage with respect to the release of the Excess Land, (E) all
parking located on the Excess Land as of the Commencement Date has been
relocated to the Retained Premises in a manner satisfactory to Landlord and (F)
all Costs of Landlord, Lender and Tenant in connection with the conveyance of
the Excess Land and in complying with the above conditions, including reasonable
attorneys' fees, shall be borne solely by Tenant. Landlord, as record title
holder to the Excess Land, shall cooperate with Tenant in obtaining a lawful
subdivision of the Leased Premises with separate parcels consisting of the
Excess Land and the Retained Premises, at no cost to Landlord. If Landlord
conveys the Excess Land under clauses (ii) or (iii) above, then, except for
Surviving Obligations this Lease shall terminate with respect to the Excess
Land, but shall remain in full force and effect with respect to the Retained
Premises, provided, however, that in no event will the release of the Excess
Land from this Lease amend, reduce or modify any of the obligations and
liabilities of Tenant hereunder, including the obligations to pay Basic Rent in
the amount set forth in Exhibit "D" hereto.

          (c)  Any act which Landlord is permitted to perform under this Lease
may be performed at any time and from time to time by Landlord or any person or
entity designated by Landlord. Each appointment of Landlord as attomey-in-fact
for Tenant hereunder shall be effective as long as an Event of Default has
occurred and is continuing and is irrevocable and coupled with an interest.
Except as otherwise specifically provided herein, Landlord shall not
unreasonably withhold or delay its consent whenever such consent is required
under this Lease, provided, however, with respect to Paragraph 21, Landlord
shall be deemed to act reasonably if such consent is governed by the terms set
forth in Paragraph 21. Time is of the essence with respect to the performance by
each of Tenant and Landlord of its respective obligations under this Lease.

          (d)  Landlord shall in no event be construed for any purpose to be a
partner, joint venturer or associate of Tenant or of any subtenant, operator,
concessionaire or licensee of Tenant with respect to any of the Leased Premises
or otherwise in the conduct of their respective businesses.

          (e)  This Lease and any documents which may be executed by Tenant
on or about the effective date hereof at Landlord's request constitute the
entire agreement between the parties and supersede all prior understandings and
agreements, whether written or oral, between the parties hereto relating to the
Leased Premises and the transactions provided for herein. Landlord and Tenant
are business entities having substantial experience with the subject matter of
this Lease and have each fully participated in the negotiation and drafting of
this Lease. Accordingly, this Lease shall be construed without regard to the
rule that ambiguities in a document are to be construed against the drafter.

          (f)  This Lease may be modified, amended, discharged or waived only
by an agreement in writing signed by the party against whom enforcement of any
such modification, amendment, discharge or waiver is sought.

          (g)  The covenants of this Lease shall run with the land and bind
Tenant, its successors and assigns and all present and subsequent encumbrancers
and subtenants of any of the Leased Premises, and shall inure to the benefit of
Landlord, its successors and assigns. If there is more than one Tenant, the
obligations of each shall be joint and several.

          (h)  If any one or more of the provisions contained in this Lease
shall for any reason be held to be invalid, illegal or unenforceable in any
respect, such invalidity, illegality or unenforceability shall not affect any
other provision of this Lease, but this Lease shall be construed as if such
invalid, illegal or unenforceable provision had never been contained herein.

          (i)  This Lease shall be governed by and construed and enforced in
accordance with the Laws of the State.

                                                                       EXHIBIT D

                              BASIC RENT PAYMENTS

     1.   Basic Rent. Subject to the adjustments provided for in Paragraphs 2, 3
          ----------
and 4 below, Basic Rent payable in respect of the Term shall be $3,914,000 per
annum, payable quarterly in advance on each Basic Rent Payment Date, in equal
installments of $978,500 each.

     2.   CPI Adjustments to Basic Rent. The Basic Rent shall be subject to
          -----------------------------
adjustment, in the manner hereinafter set forth, for increases in the index
known as United States Department of Labor, Bureau of Labor Statistics, Consumer
Price Index, Dallas-Fort Worth, Texas, All Items, (1982-84=100) ("CPI") or the
                                                                  ---
successor index that most closely approximates the CPI. If the CPI shall be
discontinued with no successor or comparable successor index, Landlord and
Tenant shall attempt to agree upon a substitute index or formula, but if they
are unable to so agree, then the matter shall be determined by arbitration in
accordance with the rules of the American Arbitration Association then
prevailing in New York City. Any decision or award resulting from such
arbitration shall be final and binding upon Landlord and Tenant and judgement
thereon may be entered in any court of competent jurisdiction. In no event will
the Basic Rent as adjusted by the CPI adjustment be less than the Basic Rent in
effect for the three (3) year period immediately preceding such adjustment.

     3.   Effective Dates of CPI Adjustments. Basic Rent shall not be adjusted
          ----------------------------------
to reflect changes in the CPI until the third (3rd) anniversary of the Basic
Rent Payment Date on which the first full quarterly installment of Basic Rent
shall be due and payable (the "First Full Basic Rent Payment Date"). As of the
                               -----------------------------------
third (3rd) anniversary of the First Full Basic Rent Payment Date and thereafter
on the sixth (6th), ninth (9th), twelfth (12th), fifteenth (15th), eighteenth
(18th) and, if the initial Term is extended, on the twenty-first (21st), twenty-
forth (24th), and twenty-seventh (27th) anniversaries of the First Full Basic
Rent Payment Date, Basic Rent shall be adjusted to reflect increases in the CPI
during the most recent three (3) year period immediately preceding each of the
foregoing dates (each such date being hereinafter referred to as the " Basic
                                                                       -----
Rent Adjustment Date").
---------------------

     4.   Method of Adjustment for CPI Adjustment
          ---------------------------------------

          (a)  As of each Basic Rent Adjustment Date when the average CPI
determined in clause (i) below exceeds the Beginning CPI (as defined in this
Paragraph 4(a)), the Basic Rent in effect immediately prior to the applicable
Basic Rent Adjustment Date shall be multiplied by a fraction, the numerator of
which shall be the difference between (i) the average CPI for the three (3) most
recent calendar months (the "Prior Months") ending prior to such Basic Rent
                             ------------
Adjustment Date for which the CPI has been published on or before the forty-
fifth (45th) day preceding such Basic Rent Adjustment Date and (ii) the
Beginning CPI, and the denominator of which shall be the Beginning CPI. An
amount equal to the lesser of (x) the product of such multiplication or 13.30%
of the Basic Rent in effect immediately prior to such Basic Rent Adjustment Date
shall be added to the Basic Rent in effect immediately prior to such Basic Rent
Adjustment Date. As used herein, "Beginning CPI" shall mean the average CPI for
                                  -------------
the three (3) calendar months corresponding to the Prior Months, but occurring
three (3) years earlier. If the average CPI determined in clause (i) is the same
or less than the Beginning CPI, the Basic Rent will remain the same for the
ensuing three (3) year period.

          (b)  Effective as of a given Basic Rent Adjustment Date, Basic Rent
payable under this Lease until the next succeeding Basic Rent Adjustment Date
shall be the Basic Rent in effect after the adjustment provided for as of such
Basic Rent Adjustment Date.

          (c)  Notice of the new annual Basic Rent shall be delivered to Tenant
on or before the tenth (10th) day preceding each Basic Rent Adjustment Date, but
any failure to

                                       1
<PAGE>

do so by Landlord shall not be or be deemed to be a waiver by Landlord of
Landlord's rights to collect such sums. Tenant shall pay to Landlord, with ten
(10) days after a notice of the new annual Basic Rent is delivered to Tenant,
all amounts due from Tenant, but unpaid, because the stated amount as set forth
above was not delivered to Tenant at least (10) days preceding the basic Rent
Adjustment Date in question.
