     --------------------
employees of the Lessee, to be designated by the Lessee, as the authorized
representative or representatives of the Lessor to accept delivery on behalf of
the Lessor of the Property identified on the Acquisition Request or an Equipment

          (a)  The Lessee hereby agrees that such acceptance of delivery by such
authorized representative or representatives and the execution and delivery by
the Lessee on the Land Interest Acquisition Date of a Lease Supplement in the
form of Exhibit A hereto (appropriately completed) shall, without further act,

and the other Operative Documents on the terms set forth therein and herein; and
that the Improvements (i) shall be deemed to be included in the leasehold estate
of this Lease as of the Improvements Closing Date, and (ii) shall be subject to
the terms and conditions of this Lease on the Improvements Closing Date.

          (c)  The Lessee hereby agrees that such acceptance of delivery by such
authorized representative or representatives and the execution and delivery
by the Lessee of an Equipment Schedule in the form of Exhibit C hereto
                                                      ---------

respect to the acquisition of Equipment shall, without further act,
constitute the irrevocable acceptance of the Equipment which is the subject
thereof for all purposes of this Lease and the other Operative Documents on
the terms set forth therein and herein, and that the Equipment (i) shall be
deemed to be included in the leasehold estate of this Lease as of the
Improvements Closing Date, and (ii) shall be subject to the terms and
conditions of this Lease as of the Improvements Closing Date.

2.3  Lease Term. The term of this Lease (the "Term") with respect to the
     ----------
Land Interest shall begin on the Land Interest Acquisition Date, and with
respect to the Improvements and the Equipment, shall begin on the Improvements
Closing Date, and shall end on the fifth anniversary of the Closing Date, unless
the Term is renewed or earlier terminated in accordance with the provisions of
this Lease.

2.4  Title. The Property is leased to the Lessee without any representation
     -----
or warranty of title, condition of the Improvements or permitted uses, express
or implied, by the Lessor and subject to the rights of parties in possession,
the existing state of title (including, without limitation, the Permitted
Exceptions) and all applicable Requirements of Law. The Lessee shall

                                       2
<PAGE>

in no event have any recourse against the Lessor for any defect in or exception
to title to the Property, other than for any such defect or exception
constituting a Lessor Lien.

                                 ARTICLE III.

3.1  Rent. (a) During the Term, commencing on the Rent Commencement Date,
     ----
the Lessee shall pay Basic Rent on each Payment Date, on the date required under
Section 22.1(i) in connection with the Lessee's exercise of the Remarketing
Option and on any date on which this Lease shall terminate.

           (b)  Neither the Lessee's inability or failure to take possession of
all or any portion of the Property when delivered by the Lessor, nor the
Lessor's inability or failure to deliver all or any portion of the Property to
the Lessee on or before the Lease Commencement Date, whether or not attributable
to any act or omission of the Lessee or any act or omission of the Lessor, or
for any other reason whatsoever, shall delay or otherwise affect the Lessee's
obligation to pay Rent for the Property from and after the Rent Commencement
Date.

3.2  Payment of Basic Rent. Basic Rent shall be paid absolutely net to the
     ---------------------
Lessor, so that this Lease shall yield to the Lessor the full amount thereof,
without setoff, deduction or reduction, whether or not the Lessee's quiet
possession of the Property is disturbed.

3.3  Supplemental Rent. The Lessee shall pay to the Lessor or the Person
     -----------------
entitled thereto any and all Supplemental Rent promptly as the same shall become
due and payable, and if the Lessee fails to pay any Supplemental Rent, the
Lessor shall have all rights, powers and remedies provided for herein or by law
or equity or otherwise in the case of nonpayment of Basic Rent. The Lessee shall
pay to the Lessor, as Supplemental Rent, among other things, on demand, to the
extent permitted by Applicable Law, interest at the applicable Overdue Rate on
any installment of Basic Rent not paid when due for the period for which the
same shall be overdue and on any payment of Supplemental Rent not paid when due
or demanded by the Lessor for the period from the due date or the date of any
such demand, as the case may be, until the same shall be paid. The expiration or
other termination of the Lessee's obligations to pay Basic Rent hereunder shall
not limit or modify the obligations of the Lessee with respect to Supplemental
Rent. Unless expressly provided otherwise in this Lease, in the event of any
failure on the part of the Lessee to pay and discharge any Supplemental Rent as
and when due, the Lessee shall also promptly pay and discharge any fine,
penalty, interest or cost which may be assessed or added under any agreement
with a third party for nonpayment or late payment of such Supplemental Rent, all
of which shall also constitute Supplemental Rent.

3.4  Method of Payment. Each payment of Rent shall be made by the Lessee to
     -----------------
the Lessor by 12:00 noon, Chicago time at the place of payment designated by
Agent in funds consisting of lawful currency of the United States of America
which shall be immediately available on the scheduled date when such payment
shall be due, unless such scheduled date shall not be a Business Day, in which
case such payment shall be made on the next succeeding Business Day or as
otherwise required by the definition of the term "Interest Period" set forth in
Appendix 1 hereto. Payments initiated after 12:00 noon, Chicago time shall be
deemed received

                                       3
<PAGE>

on the next succeeding Business Day for purposes of the second sentence of
Section 3.3 hereof, but shall be deemed received on the same day for purposes of
Section 17.1 hereof.

                                  ARTICLE IV.

4.1  Utility Charges. Subject to the Lessee's rights under the terms of
     ---------------
Article XIII relating to permitted contests, the Lessee shall pay or cause to be
paid all charges for electricity, power, gas, oil, water, telephone, sanitary
sewer service and all other rents and utilities used in or on the Property
during the Term. The Lessee shall be entitled to receive any credit or refund
with respect to any utility charge paid by the Lessee and the amount of any
credit or refund received by the Lessor on account of any utility charges paid
by the Lessee, net of the costs and expenses reasonably incurred by the Lessor
in obtaining such credit or refund, shall be promptly paid over to the Lessee.
All charges for utilities imposed with respect to the Property for a billing
period during which this Lease expires or terminates shall be adjusted and
prorated on a daily basis between the Lessor and the Lessee, and each party
shall pay or reimburse the other for each party's pro rata share thereof, except
that to the extent the Lessee retains possession of the Property after
termination or expiration of this Lease, no such adjustment and proration shall
be made.

                                  ARTICLE V.

5.1  Quiet Enjoyment. Subject to the rights of the Lessor contained in
     ---------------
Section 17.2 and the other terms of this Lease and so long as no Lease Event of
Default shall have occurred and be continuing, the Lessee shall peaceably and
quietly have, hold and enjoy the Property for the applicable Term, free of any
claim or other action by the Lessor or anyone rightfully claiming by, through or
under the Lessor (other than the Lessee or the Construction Agent) with respect
to any matters arising from and after the applicable Lease Commencement Date.

                                  ARTICLE VI.

6.1  Net Lease. This Lease shall constitute a net lease. It is the further
     ---------
express intent of the Lessor and the Lessee that the obligations of the Lessor
and the Lessee hereunder shall be separate and independent covenants and
agreements and that the Basic Rent and Supplemental Rent, and all other charges
and sums payable by the Lessee hereunder, shall commence at the times provided
herein and shall continue to be payable in all events unless the obligations to
pay the same shall be terminated pursuant to an express provision in this Lease.
Any present or future law to the contrary notwithstanding, this Lease shall not
terminate, nor shall the Lessee be entitled to any abatement, suspension,
deferment, reduction, setoff, counterclaim, or defense (other than the defense
of payment) with respect to the Rent, nor shall the obligations of the Lessee
hereunder be affected (except as expressly herein permitted and by performance
of the obligations in connection therewith) by reason of: (i) any defect in the
condition, merchantability, design, construction, quality or fitness for use of
the Property or any part thereof, or the failure of the Property to comply with
all Requirements of Law and Insurance Requirements, including any inability to
occupy or use the Property by reason of such non-compliance; (ii) any damage to,
removal, abandonment, salvage, loss, contamination of or Release from, scrapping
or destruction of, or any requisition or taking of the Property or any part

                                       4
<PAGE>

thereof; (iii) any restriction, prevention or curtailment of or interference
with any use of the Property or any part thereof including eviction; (iv) any
defect in title to or rights to the Property or any Lien on such title or rights
or on the Property (other than Lessor Liens); (v) any change, waiver, extension,
indulgence or other action or omission or breach in respect of any obligation or
liability of or by the Lessor, the Agent or any Participant; (vi) any
bankruptcy, insolvency, reorganization, composition, adjustment, dissolution,
liquidation or other like proceedings relating to the Lessee, the Lessor, the
Agent, any Participant or any other Person, or any action taken with respect to
this Lease by any trustee or receiver of the Lessee, the Lessor, the Agent, any
Participant or any other Person, or by any court, in any such proceeding; (vii)
any claim that the Lessee has or might have against any Person, including
without limitation the Lessor, any vendor, manufacturer, contractor of or for
the Property, the Agent or any Participant; (viii) any failure on the part of
the Lessor to perform or comply with any of the terms of this Lease, any other
Operative Document or any other agreement; (ix) any invalidity or
unenforceability or illegality or disaffirmance of this Lease, against or by the
Lessee or any provision hereof or any of the other Operative Documents or any
provision of any thereof; (x) the impossibility or illegality of performance by
the Lessee, the Lessor or both; (xi) any action by any court, administrative
agency or other Governmental Authority; (xii) any restriction, prevention or
curtailment of or interference with the construction on or any use of the
Property or any part thereof; or (xiii) any other cause or circumstances whether
similar or dissimilar to the foregoing and whether or not the Lessee shall have
notice or knowledge of any of the foregoing.  The parties intend that the
obligations of the Lessee hereunder shall be covenants and agreements that are
separate and independent from any obligations of the Lessor hereunder or under
any other Operative Document and the obligations of the Lessee shall continue
unaffected unless such obligations shall have been modified or terminated in
accordance with an express provision of this Lease.

6.2  No Termination or Abatement. The Lessee shall remain obligated under
     ---------------------------
this Lease in accordance with its terms and shall not take any action to
terminate (except as provided herein), rescind or avoid this Lease,
notwithstanding any action for bankruptcy, insolvency, reorganization,
liquidation, dissolution, or other proceeding affecting the Lessor, the Agent,
any Participant or the Lessee or any action with respect to this Lease or any
Operative Document which may be taken by any trustee, receiver or liquidator of
the Lessor, the Agent, any Participant or the Lessee or by any court with
respect to the Lessor, the Agent or any Participant. The Lessee hereby waives,
to the extent permitted by Applicable Law, all right (i) to terminate or
surrender this Lease (except as provided herein) or (ii) to avail itself of any
abatement, suspension, deferment, reduction, setoff, counterclaim or defense
(other than the defense of payment) with respect to any Rent. The Lessee shall
remain obligated under this Lease in accordance with its terms and the Lessee
hereby waives, to the extent permitted by Applicable Law, any and all rights now
or hereafter conferred by statute or otherwise to modify or to avoid strict
compliance with its obligations under this Lease. Notwithstanding any such
statute or otherwise, the Lessee shall be bound by all of the terms and
conditions contained in this Lease.

                                 ARTICLE VII.

7.1  Nature of Transaction; Intent of the Parties. (a) It is the intent of
     --------------------------------------------
the parties hereto that: (i) this Lease constitutes an "operating lease"
pursuant to Statement of Financial

                                       5
<PAGE>

Accounting Standards No. 13, as amended and interpreted, for purposes of the
Lessee's financial reporting, and (ii) for purposes of federal, state, and local
income or franchise taxes and for any other tax imposed on or measured by
income, the transaction contemplated hereby is a financing arrangement and
preserves ownership in the Property in the Lessee. The parties shall take no
action inconsistent with such intention. Nevertheless, the Lessee acknowledges
and agrees that neither the Agent, the Lessor nor any Participant has made any
representations or warranties to the Lessee concerning the tax, accounting or
legal characteristics of the Operative Documents and that the Lessee has
obtained and relied upon such tax, accounting and legal advice concerning the
Operative Documents as it deems appropriate.

          (b)  Anything to the contrary in the Operative Documents
notwithstanding, the Lessor and the Lessee intend and agree that with respect to
the nature of the transactions evidenced by this Lease in the context of the
exercise of remedies under the Operative Documents, including, without
limitation, in the case of any insolvency or receivership proceedings or a
petition under the United States bankruptcy laws or any other applicable
insolvency laws or statute of the United States of America or any State or
Commonwealth thereof or any foreign country affecting the Lessee, the Lessor, or
any Participant or any enforcement or collection actions arising out of or
relating to bankruptcy or insolvency laws, (i) the transactions evidenced by
this Lease shall be deemed to be loans made by the Lessor and the Participants
as unrelated third party lenders to the Lessee secured by the Property, (ii) the
obligations of the Lessee under this Lease to pay Basic Rent, Supplemental Rent,
Asset Termination Value, the Land Residual Value Guarantee Amount or the
Improvements Residual Value Guarantee Amount in connection with a purchase of
the Property pursuant to this Lease shall be treated as payments of interest on
and principal of, respectively, loans from the Lessor and the Participants to
the Lessee, and (iii) this Lease grants a security interest and mortgage or deed
of trust or lien, as the case may be, in the Property to the Lessor and assigned
by the Lessor to the Agent for the benefit of the Participants to secure the
Lessee's performance under and payment of all amounts under this Lease and the

that, for purposes of filing federal, state and local returns, reports and other
statements relating to income or franchise taxes, or any other taxes imposed
upon or measured by income, (i) the Lessee shall be entitled to take any
deduction, credit, allowance or other reporting position consistent with its
status as owner of the Property; and (ii) neither the Lessor nor any Participant
shall take an initial position on its federal, state and local returns, reports
and other statements relating to income or franchise taxes that is inconsistent
with the Lessee's status as owner of the Property.

          (d)  If the transactions evidenced by this Agreement and the other
Operative Documents can no longer be treated as an operating lease pursuant to
GAAP for accounting purposes, all provisions in the Operative Documents limiting
the Lessee's obligation to pay the Asset Termination Value (including the
Remarketing Option) on the Expiration Date shall no longer apply. If any such
change in accounting treatment shall occur, the Lessee, the Lessor, the Agent
and the Participants shall negotiate in good faith to enter into such amendments
to the Operative Documents as may be reasonably necessary or desirable to
reflect the foregoing.

described loans from the Lessor and the Participants to the Lessee, (i) this
Lease shall also be deemed to be a security agreement and financing statement
within the meaning of Article 9 of the Uniform Commercial Code (and

lien and security interest in all of the Lessee's right, title and interest in
and to the Property and all proceeds of the conversion, voluntary or
involuntary, of the foregoing into cash, investments, securities or other

security interest in the Property to Lessor to secure such loans); (iii) the
possession by the Lessor or any of its agents of any notes and such other items

      -----------------------------------------------------
procure and carry commercial general liability insurance, including contractual
liability, for claims for injuries or death sustained by persons or damage to
property while on the Property and such other general liability coverages as are
ordinarily procured by Persons who own or operate similar properties and
consistent with prudent business practice, which policies shall include
contractual liability endorsements covering the Lessee's indemnification
obligations in Section 13.1 of the Participation Agreement. Such insurance shall
be on terms and in amounts (which shall be acceptable to the Lessor and in the
event of liability insurance shall be maintained at a

                                       13

level set forth on Schedule 14.2) that are no less favorable than insurance
                   -------------
maintained by the Lessee with respect to similar properties that it owns and
that are in accordance with prudent business practice and may be provided under
blanket policies maintained by or on behalf of the Lessee. The policy shall be
endorsed to name the Lessor, the Agent and each Participant as additional
insureds. The policy shall also specifically provide that the policy shall be
considered primary insurance which shall apply to any loss or claim before any
contribution by any insurance which the Lessor, the Agent or the Participants
may have in force. The Lessee shall, in the construction of the Improvements and
the operation of the Property (including in connection with any Modifications
thereof) comply with the applicable workers' compensation laws and protect the
Lessor, the Agent and the Participants against any liability under such laws.

14.2  Hazard and Other Insurance.  The Lessee shall keep, or cause to be kept,
      --------------------------
the Property insured against loss or damage by fire, flood, earthquake and
other risks in an amount not less than the greater of the amount set forth on
Schedule 14.2 and the then current replacement costs of the buildings and
-------------
improvements on the Property and on terms that are no less favorable than
insurance covering other similar properties owned or leased by the Lessee or
any of its Affiliates and that are in accordance with prudent business
practice.  The Lessee may provide such coverage under blanket policies
maintained by or on behalf of the Lessee; provided, that if the Lessee does not
                                          --------
elect to terminate the Lease pursuant to Article XVI hereof following the
                                         -----------
occurrence of an event covered by any such blanket policy, the proceeds of any
such blanket policy shall be applied first, to the exclusion of other facilities
covered by such policy other than the Property, to the repair, rebuilding and
restoration of any damage to the Property. Prior to the Completion Date, no
insurance coverage required under this Section 14.2 shall be subject
                                       ------------
to any deductible.  During the construction of any Improvements the
Lessee shall also maintain builders' risk insurance.  Each policy of insurance
maintained by the Lessee pursuant to this Section 14.2 shall provide that all
                                          ------------
insurance proceeds in respect of any loss or occurrence shall be paid to and
adjusted solely by the Agent (at the expense of the Lessee) during the
Construction Period and thereafter, by (and such proceeds shall be paid to) the
Lessee, except from and after the date on which the insurer receives written
notice from the Lessor or the Agent that a Lease Event of Default exists (and
unless and until such insurer receives written notice from the Lessor or the
Agent that all Lease Events of Default have been cured), all losses shall be
adjusted solely by, and all insurance proceeds shall be paid solely to, the
Agent (or the Lessor if the Participation Interests have been fully paid) for
application pursuant to Article XV.  The costs and expenses of all insurance
                        ----------
required under this Section 14.2 (x) shall be paid by the Lessor (and funded as
                    ------------
an Advance funded by the Participants and capitalized as provided in Section
3.7(e)(i) of the Participation Agreement), if arising prior to the Completion
Date, and (y) from and after the Completion Date, shall be at the sole cost and

in effectand naming the Lessor, the Agent and each Participant as additional
insureds and, with respect to the insurance required under Section 14.2,

                                       14
<PAGE>

14.3(c).  Such policies and certificates in respect thereof shall include
-------
a provision for thirty (30) days' advance written notice by the insurer to the
Lessor and the Agent in the event of cancellation of or any significant
reduction in the coverage provided by such insurance.

          (b)  The Lessee agrees that the insurance policy or policies required
by Sections 14.1 and 14.2 shall include (i) an appropriate clause pursuant to
   -------------     ----
which such policy shall provide that it will not be invalidated should the
Lessee waive, in writing, prior to a loss, any or all rights of recovery
against any party for losses covered by such policy, and that the insurance
in favor of the Lessor, the Agent and the Participants, and their
respective rights under and interests in said policies shall not be
invalidated or reduced by any act or omission or negligence of the Lessee
or any other Person having any interest in the Property, and (ii) a so-
called "Waiver of Subrogation Clause".  The Lessee hereby waives any and
all such rights against the Lessor, the Agent and the Participants to the
extent of payments made under such policies.


          (c)  All such insurance shall be written by reputable insurance
companies that are financially sound and solvent and otherwise reasonably
appropriate considering the amount and type of insurance being provided by such
companies. Any insurance company selected by the Lessee which is rated in Best's
Key Rating Guide or any successor thereto (or if there be none, an organization
having a similar national reputation) shall have a general policyholder rating
of "A" and a financial rating of at least 13 in Best's Key Rating Guide or be
otherwise acceptable to the Lessor and the Agent. All insurance policies
required by Section 14.2 shall include a standard form mortgagee
            ------------
endorsement in favor of the Agent.


          (d)  The Lessor shall not carry separate insurance concurrent in kind
or form or contributing in the event of loss with any insurance required
under this Article XIV except that the Lessor may carry separate liability
           -----------
insurance (at its sole cost) so long as (i) the Lessee's insurance is
designated as primary and in no event excess or contributory to any insurance
the Lessor may have in force which would apply to a loss covered under the
Lessee's policy and (ii) each such insurance policy will not cause the Lessee's
insurance required under this Article XIV to be subject to a coinsurance
                              -----------
exception of any kind.


          (e)  The Lessee shall pay as they become due all premiums for the
insurance required by Section 14.1 and, from and after the Completion Date,
                      ------------
Section 14.2, and shall renew or replace each policy prior to the expiration
------------
date thereof.  During the Construction Period, at the time each of the Lessee's
insurance policies is renewed (but in no event less frequently than once
each year),  the Lessee shall deliver to the Lessor and the Agent certified
copies of the insurance policies required by this Article XIV to be
                                                  -----------
maintained by the Lessee with respect to the Property.  After the
Construction Period, at the time each of the Lessee's insurance policies is
renewed (but in no event less frequently than once each year), the Lessee
shall deliver to the Lessor and the Agent certificates of insurance with
respect to the insurance policies required by this Article XIV to be
                                                   -----------

        (f)  The Lessee hereby waives, releases and discharges the Lessor, the
Agent and each Participant and their agents and employees from all claims
whatsoever arising out of loss, claim, expense or damage to or destruction
covered or coverable by insurance required under this Article XIV
                                                      -----------
notwithstanding that such loss, claim, expense or damage may have been

                                       15
<PAGE>

caused by the Lessor, the Agent or any Participant or any of their agents or
employees, and the Lessee agrees to look to the insurance coverage only in the
event of such loss.

this Article XV and (in the event the Lessee delivers, or is obligated
     ----------
to deliver, a Termination Notice) Article XVI, and prior to the
                                  -----------
occurrence and continuation of a Lease Event of Default, the Lessee shall
be entitled to receive (and the Lessor shall pay over to the Lessee, if
received by the Lessor, and hereby irrevocably assigns to the Lessee all
of the Lessor's right, title and interest in) any award, compensation or
insurance proceeds to which the Lessee or the Lessor may become entitled
by reason of their respective interests in the Property (i) if all or a
portion of the Property is damaged or destroyed in whole or in part by a
Casualty or (ii) if the use, access, occupancy, easement rights or title
to the Property or any part thereof, is the subject of a Condemnation;
provided, however, subject to Article XIV, if a Lease Event of Default
                              -----------
shall have occurred and be continuing or if any such proceeds are
received by the Lessee during the Construction Period, such award,
compensation or insurance proceeds shall be paid directly to the Agent or,
if received by the Lessee, shall be held in trust for the Agent, and shall
be paid over by the Lessee to the Agent (or, if the Participation
Interests have been fully paid, to the Lessor) and held in accordance with
the terms of this paragraph (a). If, contrary to such provision, any such
                  -------------
award, compensation or insurance proceeds are paid to the
Lessor or the Lessee rather than to the Agent, the Lessor and the Lessee,
as the case may be, hereby agree to transfer any such payment to the
Agent. All amounts held by the Lessor or the Agent under the preceding
sentences on account of any award, compensation or insurance proceeds
either paid directly to the Lessor or the Agent or turned over to the
Lessor or the Agent (whether arising prior to or after the Completion
Date) shall either be (i) paid to the Lessee for the repair of damage
caused by such Casualty or Condemnation in accordance with paragraph (e)
of this Section 15.1, or (ii) applied to the purchase price of

the Property on Termination Date resulting from a Casualty or
Condemnation in accordance with paragraph (d) of this Section 15.1 or
                                ------------          ------------

------------     ------------
the Lessee.

          (b)  In any proceeding or action under the control of the Lessor or
     the Agent pursuant to the terms of Section 14.2, the Lessee may
                                        ------------
     participate and shall pay all expenses of such proceeding and its
     participation. At the Lessee's reasonable request, and at the Lessee's sole
     cost and expense, the Lessor and the Agent shall participate in any such
     proceeding, action, negotiation, prosecution or adjustment under the
     control of the Lessee. The Lessor and the Lessee agree that this Lease
     shall control the rights of the Lessor and the Lessee in and to any such
     award, compensation or insurance payment.

          (c) If the Lessor or the Lessee shall receive notice of a Casualty or
     of an actual, pending or threatened Condemnation of the Property or any
     interest therein, the Lessor or the Lessee, as the case may be, shall give
     notice thereof to the other and to the Agent promptly after the receipt of
     such notice.

          (d) In the event of a Casualty or receipt of notice by the Lessee or
     the Lessor of a Condemnation, the Lessee may deliver to the Lessor and the
     Agent a Termination Notice

     does not deliver a Termination Notice within thirty (30) days after
     such occurrence, then this Lease shall (subject to the terms and

     Property pursuant to paragraph (e) of this Section 15.1 and otherwise in
                          -------------         ------------
     accordance with this Lease.  If the Lessee delivers a Termination Notice
     within thirty (30) days after such occurrence, a Significant Event shall
     irrevocably be deemed to have occurred with respect to the Property, and,
     in such event, this Lease shall terminate and the Lessee shall purchase the
     Property on the next Payment Date (but in no event to exceed thirty (30)
     days after such occurrence) (a "Termination Date") pursuant to Article XVI
                                     -----------------              -----------

     shortfall), promptly and diligently repair any damage to the Property
     caused by such Casualty or Condemnation or substitute new Equipment for the
     affected Equipment in conformity with the requirements of Sections 10.1
                                                               -------------

     affecting the Property and in compliance with all applicable Requirements

discretion shall determine, without limiting any other right or remedy the

limitation, the obligation of the Lessee to purchase the Property as set forth
in Section 20.3):
   -------------

        (a)  The Lessor may, by notice to the Lessee, terminate the Commitments
and rescind or terminate this Lease as to all or any portion of the Property as
of the date specified in such notice; however, (i) no reletting, reentry or
taking of possession of the Property (or any portion thereof) by the Lessor will
be construed as an election on the Lessor's part to terminate this Lease unless
a written notice of such intention is given to the Lessee, (ii) notwithstanding
any reletting, reentry or taking of possession, the Lessor may at any time
thereafter elect to terminate this Lease for a continuing Lease Event of
Default, and (iii) no act or thing done by the Lessor or any of its agents,

        (b)  The Lessor may (i) demand that the Lessee, and the Lessee shall
upon the written demand of the Lessor, return the Property promptly to the
Lessor in the manner and condition required by, and otherwise in accordance with
all of the provisions of, Articles VIII, IX and X hereof as if the Property were
                          -------------  --     -
being returned at the end of the Term, and the Lessor shall not be liable for
the reimbursement of the Lessee for any costs and expenses incurred by the
Lessee in connection therewith and (ii) without prejudice to any other remedy
which the Lessor

                                       22
<PAGE>

may have for possession of the Property, and to the extent and in the manner
permitted by Applicable Law, enter upon the Property and take immediate
possession of (to the exclusion of the Lessee) the Property or any part thereof
and expel or remove the Lessee and any other Person who may be occupying the
Property, by summary proceedings or otherwise, all without liability to the
Lessee for or by reason of such entry or taking of possession, whether for the
restoration of damage to property caused by such taking or otherwise and, in
addition to the Lessor's other damages, the Lessee shall be responsible for all
costs and expenses incurred by the Lessor and/or the Agent or the Participants
in connection with any reletting, including, without limitation, brokers' fees
and all costs of any alterations or repairs made by the Lessor;

        (c)  The Lessor may (i) sell all or any part of the Property at public
or private sale, as the Lessor may determine, pursuant to such notices and
procedures as may be required by Applicable Law, free and clear of any rights of
the Lessee and without any duty to account to the Lessee with respect to such
action or inaction or any proceeds with respect thereto (except to the extent
required by clause (ii) below if the Lessor shall elect to exercise its rights
            -----------
thereunder) in which event the Lessee's obligation to pay Basic Rent hereunder
for periods commencing after the date of such sale shall be terminated or
proportionately reduced, as the case may be; and (ii) if the Lessor shall so
elect, demand that the Lessee pay to the Lessor, and the Lessee shall pay to the
Lessor, on the date of such sale, as liquidated damages for loss of a bargain
and not as a penalty (the parties agreeing that the Lessor's actual damages
would be difficult to predict, but the aforementioned liquidated damages
represent a reasonable approximation of such amount) (in lieu of Basic Rent due
for periods commencing on or after the Payment Date coinciding with such date of
sale (or, if the sale date is not a Payment Date, the Payment Date next
preceding the date of such sale)), an amount equal to (subject to Section
                                                                  -------
17.2(h)) (A) the excess, if any, of (1) the Asset Termination Value calculated
-------

Payment Date) less the aggregate amount the Cash Collateral, if any, permitted

incurred by the Lessor, the Agent and the Participants incident to such
conveyance, including, without limitation, repossession costs, brokerage
commissions, prorations, transfer taxes, fees and expenses for counsel, title
insurance fees, survey costs, recording fees, and any repair or alteration
costs); plus (B) interest at the Overdue Rate on the foregoing amount from such
Payment Date until the date of payment; provided, that the Lessor shall deliver
                                        --------
all proceeds from the sale of the Property and other amounts received hereunder
to the Agent for application as provided in Sections 3.14 and 3.17 of the
Participation Agreement.

        (d)  [Reserved]

        (e)  Unless the Property has been sold in its entirety, the Lessor may,
subject to Section 17.2(i), whether or not the Lessor shall have exercised or
           ---------------
shall thereafter at any time exercise any of its rights under paragraph (b), (c)
                                                              -------------  ---
or (d) of this Section 17.2 with respect to the Property or portions thereof,

not earlier than 10 days after the date of such notice, that the Lessee
purchase, on such Termination Date, the Property (or the remaining portion
thereof) in accordance with the provisions of Article XIX and Section 20.3;
                                              -----------     ------------

                                       23
<PAGE>

        (f)  The Lessor may exercise any other right or remedy that may be
available to it under the Operative Documents or otherwise under Applicable Law,
or proceed by appropriate court action (legal or equitable) to enforce the terms
hereof or to recover damages for the breach hereof. Separate suits may be
brought to collect any such damages for any period(s), and such suits shall not
in any manner prejudice the Lessor's right to collect any such damages for any
subsequent period(s), or the Lessor may defer any such suit until after the
expiration of the Term, in which event such suit shall be deemed not to have
accrued until the expiration of the Term;

        (g)  The Lessor may retain and apply against the Lessor's damages all
sums which the Lessor would, absent such Lease Event of Default, be required to
pay to, or turn over to, the Lessee pursuant to the terms of this Lease;

        (h)  Notwithstanding anything contained in this Lease to the contrary,
in the event that the Lease Event of Default resulting in the exercise of
remedies by the Lessor hereunder is solely a Lease Event of Default described in
Section 17.1(l) occurring during the Construction Period, the Lessee shall, at
---------------
the request of the Lessor, (i)(A) return the Property to the Lessor or a Person
designated by the Lessor on a date specified by the Lessor (which date shall
constitute the Expiration Date) and/or (B) remarket the Property for the Lessor
as the Lessor's agent subject to the Lessor's direction and, in each case,
comply with Section 19.1(b) and, to the extent applicable, Section 19.2, and
            ---------------                                ------------
(ii) pay to the Lessor (A) the maximum Residual Value Guarantee Amount on the
date that is ten (10) days after the date the Lessor furnishes the Lessee with
notice that it will require the Lessee to return or remarket the Property,
provided that the Lessor may recover from the Lessee, and the Lessee shall be
--------
obligated to pay to the Lessor the Asset Termination Value as of such date
(notwithstanding the limitation to maximum Residual Value Guarantee Amount
contained in clause (A) above) if a Lease Event of Default under Section 17.1(f)
                                                                 ---------------
or (g) shall have occurred or if the Lease Event of Default described in Section
   ---                                                                   -------
17.1(l) arose out of a Fully Indemnifiable Event or constituted an Environmental
-------
Obligation. If the Lessee has paid the Residual Value Guarantee Amount as
required herein, proceeds from a sale of the Property pursuant to this Section
                                                                       -------
17.2(h) or, if not sold as provided in this Section 17.2(h), from a sale of the
-------                                     ---------------
Property occurring thereafter, shall be distributed as provided in Section 3.14
of the Participation Agreement.


        (i)  Notwithstanding anything contained in this Lease to the contrary,
in the event that the Lease Event of Default resulting in the exercise of
remedies by the Lessor hereunder is solely a Lease Event of Default described in
Section 17.1(q) the Lessee shall have the option or, if the Lessor terminates
---------------
this Lease, the Lessee shall be required to elect to (i) remarket the Property
for 180 days after the occurrence of such Event of Default in accordance with
Article XXII hereof (which period shall constitute the Marketing Period), with
------------
the purchase of the Property to be consummated no later than the date that is
180 days following the occurrence of such Lease Event of Default (which date
shall constitute the Expiration Date if such option is exercised or required to
be exercised), or (ii) exercise its Purchase Option under Section 20.1 hereof,
                                                          ------------
with the purchase of the Property by the Lessee to be consummated, and the other
payments required thereunder to be made to the Lessor, on the next Payment Date
following the occurrence of such Lease Event of Default (which date shall
constitute the Expiration Date if such option is exercised). The Lessee shall
notify the Lessor within ten (10)

                                       24
<PAGE>

days after the occurrence of such Lease Event of Default which option it is
exercising. If the Lessee elects to remarket the Property the Lessee shall pay
to the Lessor (i) the maximum Land Interest Residual Value Guarantee Amount and
Improvements Residual Value Guarantee Amount on the date the Lessee furnishes
such notice of exercise of the Remarketing Option (or, if the Lessor elects, on
the date that is ten (10) days after the Lessor furnishes the Lessee notice that
it will require the Lessee to remarket or purchase the Property), (ii) all
breakage costs incurred by the Participants for the duration of all then current
Interest Periods under the Participation Agreement with respect to the amount so
paid following notices thereof by the Agent, (iii) Basic Rent when due with
respect to the unpaid portion of the Asset Termination Value for the duration of
the 180 day Marketing Period and (iv) the other payments required under Section
                                                                        -------

----

        (j)  In addition to the other rights and remedies set forth herein, the
Lessor shall have the right to continue this Lease in effect and, as permitted
by Section 1951.4 of the California Civil Code, to enforce, by suit or
otherwise, all covenants and conditions hereof to be performed or complied with
by the Lessee and exercise all of the Lessor's rights and remedies under this
Lease, including, without limitation, the right to recover Basic Rent and
Supplemental Rent from the Lessee as it becomes due under this Lease, even
though the Lessee shall have breached this Lease and abandoned the Property.
Acts of maintenance or preservation, or efforts by the Lessor or on the Lessor's
behalf to relet the Property, or the appointment of a receiver upon the
initiative of the Lessor to protect the Lessor's interest under this Lease shall
not constitute a termination of the Lessee's right to possession of the
Property; provided, however, that the foregoing enumeration shall not be
construed as in any way limiting the actions the Lessor may take without
terminating the Lessee's right to possession. In furtherance of the rights
hereby granted to the Lessor, and to the extent, permitted by law, the Lessee
hereby appoints the Lessor its agent and attorney-in-fact, which appointment
shall be deemed to be coupled with an interest and is irrevocable, with power of
substitution, to enter the Property upon a Lease Event of Default hereunder and
remove therefrom all persons and property (with the right to store such property
on the Property in a public warehouse or elsewhere at the cost and risk and for
the account of the Lessee) and to alter the Property in such manner as the
Lessor may deem necessary or advisable so as to put the Property in good order
and to make the same rentable and from time to time and sublet the Property or
any part thereof for such term or terms whether or not extending beyond the then
current term of this Lease (but such sublease may provide for a new and
successive lease to commence immediately upon the termination of this Lease), at
such rentals and upon such other terms as the Lessor in its sole discretion may
deem advisable, and with the right to make alterations and repairs to the
Property; and the Lessee agrees to pay to the Lessor on demand all reasonable
expenses incurred by the Lessor in such subletting, and in altering, repairing
and putting the Property in good order and condition, and in reletting the same,
including fees of attorneys and architects, and all other reasonable expenses or
commissions. The Lessor shall be the Lessee's agent and representative on the
Property in respect of all matters arising under or in connection with any such
sublease made for the Lessee by the Lessor. Under each such sublease, the Lessee
shall retain the right to enter upon and use the Property, subject to the terms
and conditions of such sublease and the rights of the sublessee thereunder. The
Lessee further agrees to pay to the Lessor, following the date of such
subletting, to and including the date provided in this Lease for the expiration
of the Term, the sums of money which would have been payable by the Lessee as
Basic Rent and Supplemental Rent,

                                       25
<PAGE>

deducting only the net amount of rent, if any, which the Lessor shall actually
receive (after deducting from the gross receipts the expenses, costs and
payments of the Lessor which in accordance with the terms of this Lease would
have been borne by the Lessee) in the meantime from and by any such subletting
of the Property, and the Lessee hereby agrees to remain liable for all sums
otherwise payable by the Lessee under this Lease, including, but not limited to,
the expenses of the Lessor aforesaid, as well as for any deficiency aforesaid.
The Lessor shall have the right from time to time to begin and maintain
successive actions or other legal proceedings against the Lessee for the
recovery of such deficiency, expenses or damages or for a sum equal to any
installments of Basic Rent or Supplemental Rent and other sums payable
hereunder, and to recover the same upon the liability of the Lessee herein
provided, which liability it is expressly covenanted shall survive the
commencement or determination of any action to secure possession of the
Property. Nothing herein contained shall be deemed to require the Lessor to wait
to begin such action or other legal proceedings until the date when this Lease
would have expired by limitation had there been no such Lease Event of Default.
Notwithstanding any such subletting without termination, pursuant to the terms
hereof, the Lessor shall retain the right to and may at any time thereafter
elect to terminate this Lease or the Lessee's right to possession of the
Property for any previous breach which remains uncured or for any subsequent
breach by giving the Lessee written notice thereof as herein provided, and in
such event the Lessee shall forfeit any rights or interest under any such
sublease and thereafter the obligations of any such sublessee shall run directly
to the Lessor for its own account. Upon application by the Lessor, a receiver
may be appointed to take possession of the Property, exercise all rights granted
to the Lessor as agent and attorney-in-fact for the Lessee set forth in this
Section 17.2(h) and apply any rentals collected from the Property as hereinabove
provided. No taking of possession of the Property or other act by the Lessor as
the agent and attorney-in-fact for the Lessee pursuant to the foregoing
provisions, nor any subletting by the Lessor for the Lessee pursuant to the
foregoing provisions, nor any such appointment of a receiver shall constitute or
be construed as an election by the Lessor to terminate this Lease or the
Lessee's right to possession of the Property unless a written notice of such
intention be given to the Lessee.

  17.3  Waiver of Certain Rights. If this Lease shall be terminated pursuant to
        ------------------------
Section 17.2, the Lessee waives, to the fullest extent permitted by law, (a) any
notice of re-entry or the institution of legal proceedings to obtain re-entry or
possession; (b) any right of redemption, re-entry or repossession; (c) the
benefit of any laws now or hereafter in force exempting property from liability
for rent or for debt or limiting the Lessor with respect to the election of
remedies; and (d) any other rights which might otherwise limit or modify any of
the Lessor's rights or remedies under this Article XVII.
                                           ------------

  17.4  Loan Remedies. If the transaction evidenced by this Agreement and the
        -------------
other Operative Documents is treated as a loan, upon the occurrence or existence
of any Event of Default and at any time thereafter unless such Event of Default
is waived, the Lessor and the Trustee may with the consent of the Required
Participants, or shall, upon instructions from the Required Participants,
exercise any one or more of the following rights and remedies in addition to
those rights and remedies set forth in Section 17.2:
                                       ------------

        (a)  Acceleration of Obligations. The Lessor may, by written notice to
             ---------------------------
the Lessee, terminate this Lease and declare all unpaid Obligations due and
payable. On such

                                       26
<PAGE>

termination date (which shall then be the Expiration Date), the Lessee shall pay
the Asset Termination Value (subject to Section 17.2(h) and (i)), all unpaid
                                        ---------------     ---
Basic Rent accrued through such date, all Supplemental Rent due and payable on
or prior to such date and all other amounts payable by the Lessee on the
Expiration Date pursuant to this Lease and the other Operative Documents.

        (b)  Uniform Commercial Code Remedies. The Lessor may exercise any or
             --------------------------------
all of the remedies granted to a secured party under the California Uniform
Commercial Code.

        (c)  Judicial Foreclosure. The Lessor may bring an action in any court
             --------------------
of competent jurisdiction to foreclose the security interest in the Property
granted to the Lessor by this Lease or any of the other Operative Documents.
Further, Lessor and/or the Trustee may bring an action or actions in a court of
competent jurisdiction to foreclose this instrument as a mortgage and to obtain
specific enforcement of the covenants of the Lessee hereunder, and the Lessee
agrees that such covenants shall be specifically enforceable by injunction or
any other appropriate equitable remedy and that for the purposes of any suit
brought hereunder the Lessee waives the defense of laches and any applicable
statute of limitations.

        (d)  Power of Sale. The Lessor may cause some or all of the Property
             -------------
including any Collateral constituting personal property, including the Cash
Collateral ("Personal Property Collateral"), to be sold or otherwise disposed of
             ----------------------------
in any combination and in any manner permitted by Applicable Law.

             (i)  Sales of Personal Property. The Lessor may dispose of any
                  --------------------------
        Personal Property Collateral separately from the sale of the Collateral
        constituting real property ("Real Property Collateral"), in any manner
                                     ------------------------
        permitted by Division 9 of the California Uniform Commercial Code,
        including any public or private sale, or in any manner permitted by any
        other applicable Governmental Rule. Any proceeds of any such disposition
        shall not cure any Event of Default or reinstate any Obligation for
        purposes of Section 2924c of the California Civil Code. In connection
        with any such sale or other disposition, the Lessee agrees that the
        following procedures constitute a commercially reasonable sale:

                  (A)  The Lessor shall mail written notice of the sale to the
             Lessee not later than thirty (30) days prior to such sale.

                  (B)  Once per week during the three (3) weeks immediately
             preceding such sale, the Lessor will publish notice of the sale in
             a local daily newspaper of general circulation.

                  (C)  Upon receipt of any written request, the Lessor will make
             the Property available to any bona fide prospective purchaser for
             inspection during reasonable business hours.

                                       27
<PAGE>

                  (D)  Notwithstanding, the Lessor shall be under no obligation
             to consummate a sale if, in its judgment, none of the offers
             received by it equals the fair value of the Property offered for
             sale.

                  (E)  If the Lessor so requests, the Lessee shall assemble all
             of the Personal Property Collateral and make it available to the
             Lessor at the site of the Land Interest. Regardless of any
             provision of this Agreement or any other Operative Document, the
             Lessor shall not be considered to have accepted any property other
             than cash or immediately available funds in satisfaction of any
             Obligation, unless the Lessor has given express written notice of
             its election of that remedy in accordance with California Uniform
             Commercial Code Section 9505.

        The foregoing procedures do not constitute the only procedures that
        may be commercially reasonable.

             (ii) Lessor's Sales of Real Property or Mixed Collateral. The
                  ---------------------------------------------------
        Lessor may choose to dispose of some or all of the Property which
        consists solely of Real Property Collateral in any manner then permitted
        by Applicable Law, including without limitation a nonjudicial trustee's
        sale pursuant to California Civil Code (S)(S)2924 et seq. In its
        discretion, the Lessor may also or alternatively choose to dispose of
        some or all of the Property, in any combination consisting of both Real
        Property Collateral and Personal Property Collateral, together in one
        sale to be held in accordance with the law and procedures applicable to
        real property, as permitted by Section 9501(4) of the California Uniform
        Commercial Code. The Lessee agrees that such a sale of Personal Property
        Collateral together with Real Property Collateral constitutes a
        commercially reasonable sale of the Personal Property Collateral. (For
        purposes of this Power of Sale, either a sale of Real Property
        Collateral alone, or a sale of both Real Property Collateral and
        Personal Property Collateral together in accordance with California
        Uniform Commercial Code Section 9501(4), will sometimes be referred to
        as a "Lessor's Sale"
              -------------

                  (A)  Before any Lessor's Sale, the Lessor shall give such
             notice of default and election to sell as may then be required by
             Applicable Law.

                  (B)  When all time periods then legally mandated have expired,
             and after such notice of sale as may then be legally required has
             been given, the Lessor shall sell the property being sold at a
             public auction to be held at the time and place specified in the
             notice of sale.

                  (C)  Neither the Lessor nor the Agent shall have any
             obligation to make demand on the Lessee before any Lessor's Sale.

                  (D)  From time to time in accordance with then Applicable Law,
             the Lessor may postpone any Lessor's Sale by public announcement at
             the time and place noticed for that sale.

                                       28
<PAGE>

                  (E)  At any Lessor's Sale, the Lessor shall sell to the
             highest bidder at public auction for cash in lawful money of the
             United States.

                  (F)  The Lessor shall execute and deliver to the purchaser(s)
             a deed or deeds conveying the Property being sold without any
             covenant or warranty whatsoever, express or implied. The recitals
             in any such deed of any matters or facts, including any facts
             bearing upon the regularity or validity of any Lessor's Sale, shall
             be conclusive proof of their truthfulness. Any such deed shall be
             conclusive against all Persons as to the facts recited in it.

                  (e)  Foreclosure Sales.
                       -----------------

                       (i)  Single or Multiple. If the Property consists of more
                            ------------------
                  than one lot, parcel or item of property, Lessor may:

                           (A)  Designate the order in which the lots, parcels
                       and/or items shall be sold or disposed of or offered for
                       sale or disposition; and

                           (B)  Elect to dispose of the lots, parcels and/or
                       items through a single consolidated sale or disposition
                       to be held or made under the power of sale granted in
                       Section 17.4(d), or in connection with judicial
                       ---------------
                       proceedings, or by virtue of a judgment and decree of
                       foreclosure and sale; or through two or more such sales
                       or dispositions; or in any other manner the Lessor may
                       deem to be in its best interests (any such sale or
                       disposition, a "Foreclosure Sale," any two or more,
                       "Foreclosure Sales").

                  If the Lessor chooses to have more than one Foreclosure Sale,
                  the Lessor at its option may cause the Foreclosure Sales to be
                  held simultaneously or successively, on the same day, or on
                  such different days and at such different times and in such
                  order as it may deem to be in its best interests. No
                  Foreclosure Sale shall terminate or affect the security
                  interests granted to the Lessor in the Property by this Lease
                  or any part of the Property which has not been sold, until all
                  of the Obligations have been paid in full.

                       (ii) Credit Bids. At any Foreclosure Sale, any Person,
                            -----------
                  including the Lessor or any Participant, may bid for and
                  acquire the Property or any part of it to the extent permitted
                  by Applicable Law. Instead of paying cash for the Property,
                  the Lessor may settle for the purchase price by crediting the
                  sales price of the Property against the Obligations in any
                  order and proportions as the Lessor in its sole discretion may
                  choose.

                  (f)  Additional Rights and Remedies.
                       ------------------------------

                      (i)  In addition to and without limitation of the rights
                  and remedies otherwise provided in this Section 17.4, Lessor
                  or its employees, acting by

                                       29
<PAGE>

                  themselves or through a court-appointed receiver, may enter
                  upon, possess, manage, operate, dispose of and contract to
                  dispose of the Property or any part thereof; negotiate with
                  governmental authorities with respect to the Property's
                  environmental compliance and remedial measures; contract for
                  goods and services, hire agents, employees and counsel, make
                  repairs, alterations and improvements to the Property
                  necessary, in Lessor's judgment, to protect or enhance the
                  security hereof; to incur the risks and obligations ordinarily
                  incurred by owners of property (without any personal
                  obligation on the part of the receiver); and/or to take any
                  and all other actions which may be necessary or desirable to
                  comply with Lessee's obligations hereunder and under the
                  Operative Documents. All sums realized by the Lessor under
                  this Section 17.4(f)(i), less all costs and expenses incurred
                  by it under this Section 17.4(f)(i), including attorneys'
                  fees, and less such sums as the Lessor deems appropriate as a
                  reserve to meet future expenses under this Section 17.4(f)(i),
                  shall be applied to any Obligations secured hereby in such
                  order as the Lessor shall determine. Neither application of
                  said sums to said indebtedness nor any other action taken by
                  the Lessor under this Section 17.4(f)(i) shall cure or waive
                  any Event of Default or notice of default hereunder or nullify
                  the effect of any such notice of default. The Lessor, or any
                  employee or agent of the Lessor, or a receiver appointed by a
                  court, may take any action or proceeding hereunder without
                  regard to (i) the adequacy of the security for the
                  indebtedness secured hereunder, (ii) the existence of a
                  declaration that the indebtedness secured hereby has been
                  declared immediately due and payable, or (iii) the filing of a
                  notice of default;

                      (ii) Lessor shall have the power and authority to execute
                  a written notice of such Event of Default and, at its
                  election, cause the Property to be sold to satisfy the
                  Obligations secured hereby. The Lessor shall give and record
                  such notice as the law then requires as a condition precedent
                  to a nonjudicial foreclosure sale. When the minimum period of
                  time required by law after such notice has elapsed, the
                  Lessor, without notice to or demand upon Lessee except as
                  otherwise required by law, shall sell the Property at the time
                  and place of sale fixed by it in the notice of sale and in
                  such order as it or the Lessor may determine, at public
                  auction to the highest bidder for cash in lawful money of the
                  United States, payable at time of sale (the Obligations hereby
                  secured being the equivalent of cash for purposes of said
                  sale). If the Property consists of several lots, parcels, or
                  items of property, the Lessor may: (i) designate the order in
                  which such lots, parcels, or items of property shall be
                  offered for sale or sold, or (ii) elect to sell such lots,
                  parcels or items through a single sale, through two or more
                  successive sales, or in any other manner the Lessor deems in
                  its best interest. The Lessee shall have no right to direct
                  the order in which the Property is sold. The Lessor may
                  postpone sale of all or any portion of the Property by public
                  announcement at such time and place of sale, and from time to
                  time thereafter may postpone such sale by public announcement
                  at such time fixed by the preceding postponement. The Lessor
                  shall deliver to the purchaser at such sale a deed or other
                  appropriate transfer instrument conveying the Property or
                  portion thereof so sold, but without any covenant or warranty,
                  express or implied. The

                                       30
<PAGE>

                  recitals in such deed of any matters of facts shall be
                  conclusive proof of the truthfulness thereof. Any person,
                  including the Lessor or the Lessee may purchase at such sale.

                  In connection with any sale or sales hereunder, the Lessor may
elect to treat any of the Property which consists of a right in action or which
is property that can be severed from the real property covered hereby or any
improvements thereon without causing structural damage thereto as if the same
were personal property or a fixture, as the case may be, and dispose of the same
in accordance with applicable law, separate and apart from the sale of real
property. Any sale of any personal property or fixtures hereunder shall be
conducted in any matter permitted by the California Uniform Commercial Code.

                  After deducting all costs, fees and expenses of the Lessor and
of this trust, including all costs of evidence of title and attorneys' fees in
connection with sale, the Lessor shall apply the proceeds of sale to payment of
all sums so expended under the terms hereof not then repaid; the payment of all
other sums then secured hereby; and the remainder, if any, to the person or
persons legally entitled thereto;

                      (iii)  Lessor shall have the power and authority to resort
                  to and realize upon the Property and any other security now or
                  hereafter held by the Lessor in such order and manner as the
                  Lessor and the Trustee may, in their sole discretion,
                  determine; and resort to any or all such security may be taken
                  concurrently or successively and in one or several
                  consolidated or independent judicial actions or lawfully taken
                  non-judicial proceedings, or both.

  17.5  Remedies Cumulative. The remedies herein provided shall be cumulative
        -------------------
and in addition to (and not in limitation of) any other remedies available at
law, equity or otherwise, including, without limitation, any mortgage
foreclosure remedies.

  17.6  The Lessee's Right to Cure. Notwithstanding any provision contained in
        --------------------------
the Lease or any other Operative Document, if a Lease Event of Default has
occurred and is continuing, the Lessee shall have the right to cure such Lease
Event of Default by (a) exercising its Purchase Option at any time prior to the
earlier of (i) the termination of the Lessee's possessory interest in the
Property, and (ii) the thirty day period following the occurrence of a Lease
Event of Default, and (b) purchasing the Property in accordance with Section
                                                                     -------
20.1 at any time prior to such time as a foreclosure upon or sale of the
----
Property has been completed.

                                ARTICLE XVIII.

  18.1  The Lessor's Right to Cure the Lessee's Lease Defaults. The Lessor,
        ------------------------------------------------------
without waiving or releasing any obligation or Lease Event of Default, may (but
shall be under no obligation to) remedy any Lease Default or Lease Event of
Default for the account and at the sole cost and expense of the Lessee,
including the failure by the Lessee to maintain the insurance required by
Article XIV (subject to the limitations set forth in Section 24.1), and may, to
                                                     ------------
the fullest extent permitted by law, and notwithstanding any right of quiet
enjoyment in favor of the

                                       31
<PAGE>

Option, Lessee or the third party acquiring such property shall grant any
easements reasonably determined to be necessary by Lessor for the benefit of the

amount equal to the Asset Termination Value that was not fully and finally paid
by such designee on such Expiration Date.

forward to each Participant) given not later than 180 days prior to the Initial
Expiration, to renew the Term for an additional one-year period commencing on
the date following the Expiration Date then in effect. No later than the date
(the "Renewal Response Date") which is ninety (90) days after such request has
been delivered to each of the Lessor and the Agent, the Lessor will notify the
Lessee in writing (with a copy to Agent) whether or not it consents to such
Renewal Request (which consent may be granted or denied in its sole discretion

Renewal Request. If the Lessor shall have consented to the Renewal Request, the
Renewal Term contemplated by such request shall become effective as of the
Expiration Date then in effect after the Lessor has consented to such Renewal
Request (each an "Extension Effective Date"); provided that such renewal shall
                  ------------------------

conditions as are set forth in this Lease for the original Term, with such
modifications thereto, if any, as the parties hereto and to the other Operative
Documents may negotiate based upon the current credit information regarding the
Lessee, interest rates and such other factors as the Lessor may consider
relevant. No more than two Renewal Terms shall be permitted hereunder.

                                 ARTICLE XXII.

  22.1  Option to Remarket. Subject to the fulfillment of each of the conditions
        ------------------
set forth in this Section 22.1, the Lessee shall have the option (the
                  ------------
"Remarketing Option") to market for the Lessor and complete the sale of all, but
 ------------------
not less than all, of the Lessor's interest in the Property on the Expiration
Date for the Lessor.

  The Lessee's effective exercise and consummation of the Remarketing Option
shall be subject to the due and timely fulfillment of each of the following
provisions as of the dates set forth below.

        (a)  Not later than one hundred eighty (180) days prior to the
Expiration Date, the Lessee shall give to the Lessor written notice of the
Lessee's exercise of the Remarketing Option, which exercise shall be irrevocable
(except by delivery of a Purchase Notice and consummation of the exercise of the
Purchase Option prior to the earlier of (i) the Expiration Date or (ii) the date
on which the Lessor enters into a binding contract to sell the Property pursuant
to the exercise of the Remarketing Option).

        (b)  The Lessee shall deliver to the Lessor an Environmental Audit of
the Property together with its notice of exercise of the Remarketing Option.
Such Environmental Audit shall be prepared by an environmental consultant
selected by the Lessor in the Lessor's

<PAGE>

reasonable discretion and shall contain conclusions reasonably satisfactory to
the Lessor as to the environmental status of the Property. If such Environmental
Audit indicates any material exceptions reasonably requiring remedy or further
investigation, the Lessee shall have also delivered a Phase Two environmental
assessment by such environmental consultant prior to the Expiration Date showing
the completion of the remediation of such exceptions, if any, in compliance with
Environmental Laws or such further investigation as required.

        (c)  On the date of the Lessee's notice to the Lessor of the Lessee's
exercise of the Remarketing Option, no Lease Event of Default or Lease Default
shall exist, and thereafter, no uncured Lease Event of Default or Lease Default
shall exist.

        (d)  The Lessee shall have completed in all material respects all
Modifications, restoration and rebuilding of the Property pursuant to Sections
                                                                      --------
11.1 and 15.1(e) (as the case may be) and shall have fulfilled in all material

respects all of the conditions and requirements in connection therewith pursuant
to said Sections, in each case by the date on which the Lessor receives the
Lessee's notice of the Lessee's exercise of the Remarketing Option (time being
of the essence), regardless of whether the same shall be within the Lessee's
control. The Lessee shall have also paid the cost of all Modifications commenced
prior to the Expiration Date. The Lessee shall not have been excused pursuant to
Section 13.1 from complying with any Applicable Law that involved the extension
------------
of the ultimate imposition of such Applicable Law beyond the last day of the
Term. Any Permitted Exceptions on the Property that were contested by the Lessee
shall have been removed.

        (e)  During the Marketing Period, the Lessee shall, as nonexclusive
agent for the Lessor, use commercially reasonable efforts to sell the Lessor's
interest in the Property on or prior to the Expiration Date (without diminishing
the Lessee's obligation to consummate the sale on the Expiration Date) and will
attempt to obtain the highest purchase price therefor and for not less than the
Fair Market Sales Value. The Lessee will be responsible for hiring and
compensating brokers and making the Property available for inspection by
prospective purchasers. The Lessee shall promptly upon request permit inspection
of the Property and any maintenance records relating to the Property by the
Lessor, any Participant and any potential purchasers, and shall otherwise do all
things necessary to sell and deliver possession of the Property to any
purchaser. All such marketing of the Property shall be at the Lessee's sole
expense. The Lessee shall allow the Lessor and any potential qualified purchaser
reasonable access to the Property for the purpose of inspecting the same.

        (f)  The Lessee shall submit all bids to the Lessor and the Agent, and
the Lessor will have the right to review the same and the right to submit any
one or more bids. All bids shall be on an all-cash basis unless the Lessor, the
Agent and the Participants shall otherwise agree in their sole discretion. The
Lessee shall procure bids from one or more bona fide prospective purchasers and
shall deliver to the Lessor and the Agent not less than ninety (90) days prior
to the Expiration Date a binding written unconditional (except as set forth
below), irrevocable offer by such purchaser or purchasers offering the highest
bid to purchase the Property. No such purchaser shall be the Lessee, or any
Subsidiary or Affiliate of the Lessee. The written offer must specify the
Expiration Date as the closing date unless the Lessor, the Agent and the
Participants shall otherwise agree in their sole discretion.

        (g)  In connection with any such sale of the Property, the Lessee will
provide to the purchaser all customary "seller's" indemnities, representations
and warranties regarding title, absence of Liens (except Lessor Liens) and the
condition of the Property, as well as such other terms and conditions as may be
negotiated between the Lessee and the purchaser. The Lessee shall have obtained,
at its cost and expense, and with the reasonable cooperation of Lessor, all
required governmental and regulatory consents and approvals and shall have made
all filings as required by Applicable Law in order to carry out and complete the
transfer of the Property. As to the Lessor, any such sale shall be made on an
"as is, with all faults" basis without representation or warranty by the Lessor
other than the absence of Lessor Liens and Liens created by the Operative
Documents. Any agreement as to such sale shall be made subject to the Lessor's
rights hereunder.

        (h)  The Lessee shall pay directly, and not from the sale proceeds, all
prorations, credits, costs and expenses of the sale of the Property, whether
incurred by the Lessor, the Participants or the Lessee, including without
limitation, the cost of all title insurance, surveys, environmental reports,
appraisals, transfer taxes, the Lessor's, the Participants' and the Agent's
reasonable attorneys' fees, the Lessee's attorneys' fees, commissions, escrow
fees, recording fees, and all applicable documentary and other transfer taxes.

        (i)  The Lessee shall pay to the Agent on the Expiration Date (or to
such other Person as the Lessor shall notify the Lessee in writing, or in the
case of Supplemental Rent, to the Person entitled thereto) an amount equal to
the Improvements Residual Value Guarantee Amount and the Land Residual Value
Guarantee Amount, plus (without duplication) all Rent and all other amounts
                  ----
hereunder which have accrued or will accrue prior to or as of the Expiration
Date, in the type of funds specified in Section 3.4 hereof.
                                        -----------

        (j)  If, within ninety (90) days prior to the Expiration Date, it is
determined (based upon the highest bid by a purchaser to purchase the Property
pursuant to paragraph (f) of this Section 22.1) that there would, after giving
            -------------         ------------
effect to the proposed sale of the Property, be a Shortfall Amount, the Lessee
(i) shall cause to be delivered to the Lessor and the Agent the End of Term
Report required by Section 13.2 of the Participation Agreement and (ii) shall on
the Expiration Date pay to the Agent (or to such other person as the Lessor
shall notify the Lessee in writing), the amounts (not to exceed the Shortfall
Amount) required to be paid pursuant to Section 13.2 of the Participation
Agreement.

        (k)  The purchase of the Property shall be consummated on the Expiration
Date following the payment by the Lessee pursuant to paragraphs (i) and (j)
                                                     --------------     ---
above and contemporaneously with the Lessee's surrender of the Property pursuant
to Section 19.1(b) and the gross proceeds (the "Gross Proceeds") of the sale of
   ---------------                              --------------
the Property (i.e., without deduction for any marketing, closing or other costs,
prorations or commissions) shall be paid directly to the Agent; provided,
                                                                --------
however, that (i) if the sum of the Gross Proceeds from such sale of the Land
-------
Interest plus the Land Interest Residual Value Guarantee Amount paid by the
Lessee pursuant to paragraph (i) above exceeds the Land Asset Termination Value
                   -------------
as of such date, then the excess shall be paid to the Lessee on the Expiration
Date, and (ii) if the sum of the Gross Proceeds from such sale of the
Improvements plus the Improvements Residual Value Guarantee Amount paid

                                       37
<PAGE>

                          -------------
Termination Value as of such date, then the excess shall be paid to the Lessee
on the Expiration Date.

        (l)  The Lessee shall not be entitled to exercise or consummate the
Remarketing Option if a circumstance that would permit the Lessor to require the
Lessee to repurchase the Property under Section 16.3 exists and is continuing.
                                        ------- ----

        (m)  No subleases affecting the Property shall be in effect on the
Expiration Date.

     If one or more of the foregoing provisions shall not be fulfilled as of the
date set forth above, then the Lessor shall declare by written notice to the
Lessee the Remarketing Option to be null and void (whether or not it has been
theretofore exercised by the Lessee) as to the Property, in which event all of
the Lessee's rights under this Section 22.1 shall immediately terminate and the
                               ------------
Lessee shall be obligated to vacate the Property on the Expiration Date and
comply with the obligations set forth in Section 22.3.  Except as expressly set
forth herein, the Lessee shall have no right, power or authority to bind the
Lessor in connection with any proposed sale of the Property.

     If the Lessee has paid the Land Interest Residual Value Guarantee Amount
and the Improvements Residual Value Guarantee Amount as required herein,

not sold as provided in this Section 22.1 from a sale of the Property occurring

        ----------------------------
obligation of the Lessee to pay Rent (including the installment of Basic Rent
due on the fifth anniversary of the Closing Date or at the end of any Renewal
Term, as the case may be) shall continue undiminished until payment in full to
the Lessor, for deposit into an account with the Agent, of the Gross Proceeds,
the Land Interest Residual Value Guarantee Amount and the Improvements Residual
Value Guarantee Amount, and (without duplication) all other amounts due to the
Lessor with respect to the Property under the Operative Documents. The Lessor
shall have the right, but shall be under no duty, to solicit bids, to inquire
into the efforts of the Lessee to obtain bids or otherwise to take action in
connection with any such sale, other than as expressly provided in this
Article XXII.
------------

  22.3  Support Obligations. In the event that (A) the Lessee does not elect to
        -------------------
purchase the Property on the Expiration Date, (B) this Lease is terminated
without a purchase of the Property by the Lessee as expressly permitted herein,
or (C) pursuant to the Lessor's exercise of remedies under Article XVII, this
                                                           ------------
Lease is terminated, the Lessee shall, upon the request of the Lessor, exercise
all commercially reasonable efforts to provide the Lessor or other purchaser of
the Property, effective on the Expiration Date or earlier termination of this
Lease, with (i) all permits, certificates of occupancy, governmental licenses
and authorizations necessary to use and operate the Property for its intended
purposes (to the extent such items are transferable), (ii) such easements,
licenses, rights-of-way and other rights and privileges in the nature of an
easement as are reasonably necessary or desirable in connection with the use,
repair, access to or maintenance

                                       38
<PAGE>

of the Property, and (iii) any service agreements, contracts or subcontracts in
existence at such time relating to the use and operation of the Property, in
each case to the extent assignable. All assignments, licenses, easements,
agreements and other deliveries required by clauses (i), (ii) and (iii) of this
Section 22.3 shall be in form satisfactory to the Lessor and shall be fully
------------
assignable (including both primary assignments and assignments given in the
nature of security) without payment of any fee, cost or other charge.

                                ARTICLE XXIII.

  23.1  Holding Over. If the Lessee shall for any reason remain in possession of
        ------------
the Property after the expiration or earlier termination of this Lease (unless
the Property is conveyed to the Lessee), such possession shall be as a tenancy
at sufferance during which time the Lessee shall continue to pay Prepaid Rent,
to the extent such possession occurs prior to the Completion Date, or
Supplemental Rent, to the extent such possession occurs from and after the
Completion Date, that would be payable by the Lessee hereunder were the Lease
then in full force and effect and the Lessee shall continue to pay Basic Rent at
an annual rate equal to 110% of the average rate of Basic Rent payable hereunder
during the Term. Such Basic Rent shall be payable from time to time upon demand
by the Lessor. During any period of tenancy at sufferance, the Lessee shall,
subject to the second preceding sentence, be obligated to perform and observe
all of the terms, covenants and conditions of this Lease, but shall have no
rights hereunder other than the right, to the extent given by law to tenants at
sufferance, to continue its occupancy and use of the Property. Nothing contained
in this Article XXIII shall constitute the consent, express or implied, of the
        -------------
Lessor to the holding over of the Lessee after the expiration or earlier
termination of this Lease (unless the Property is conveyed to the Lessee), and
nothing contained herein shall be read or construed to relieve the Lessee of its
obligations to purchase or remarket the Property on the Expiration Date pursuant
to Article XX or Article XXII or as preventing the Lessor from maintaining a
   ----------    ------------
suit for possession of the Property or exercising any other remedy available to
the Lessor at law or in equity or hereunder.

                                 ARTICLE XXIV.

  24.1  Risk of Loss. The Lessee assumes all risks of loss arising from any
        ------------
Casualty or Condemnation which arises or occurs prior to the Expiration Date or
while the Lessee is in possession of the Property and all liability for all
personal injuries and deaths and damages to property suffered by any Person or
property on or in connection with the Property which arises or occurs prior to
the Expiration Date or while the Lessee is in possession of the Property, except
in each case to the extent any such loss or liability is primarily caused by the
gross negligence or willful misconduct of a Lessor Party; provided, however,
                                                          --------  -------
that the Lessee shall have no obligation under this Section 24.1 on account of
                                                    ------------
any such loss or liability arising with respect to the Improvements only prior
to the Completion Date, except as follows:

                 (i)  The Lessee shall be liable to the Lessor under this
        Section 24.1 for all such losses and liabilities Within the Lessee's
        ------------
        Control, subject to the following:

                      (A)  if any such loss or liability is not related to an
                 inability or failure to complete construction of the
                 Improvements (or if such loss or

                                       39
<PAGE>

               liability is not related to an inability or failure to complete
               construction of the Improvements (or if such loss or liability is
               related to an inability or failure to complete construction of
               the Improvements but also constitutes or arises out of a Fully
               Indemnifiable Event), the Lessee's obligations in this Section
                                                                      -------
               24.1 shall not be subject to any monetary limitation; and
               ----

                    (B)  if such loss or liability is related to an inability or
               failure to complete construction of the Improvements and such
               loss or liability does not constitute or arise out of a Fully
               Indemnifiable Event, the Lessee's monetary obligation provided in
               this Section 24.1, together with all other amounts payable prior
                    ------------
               to the Completion Date under Section 9.1(b)(i) of the
               Participation Agreement, Section 9.3(b)(i) of the Participation
               Agreement, clause (5)(A)(ii) of Section 13.1 of the Participation
               Agreement or Section 13.10 of the Participation Agreement and any
               similarly limited payment obligation of the Lessee in connection
               with the return or sale of the Property under this Lease or the
               Construction Agency Agreement, shall not exceed the maximum Land
               Interest Residual Value Guarantee Amount and Improvements
               Residual Value Guarantee Amount.

               (ii) If any Lessor Party incurs any such loss or liability for
          which the Lessee is not liable pursuant to this Section 24.1, the
                                                          ------------
          amount of such loss or liability shall, if such Lessor Party shall so
          request by a written notice to the Lessor and the Lessor shall give
          its prior written consent thereto, be capitalized pursuant to Section
          3.7(e)(ii) of the Participation Agreement.

TO THE FULLEST EXTENT PERMITTED BY LAW, THE LESSEE HEREBY WAIVES THE PROVISIONS
OF THE CALIFORNIA CIVIL CODE SECTIONS 1932(1),  1932(2) AND 1933(4), AND ANY AND
ALL OTHER APPLICABLE EXISTING OR FUTURE LAWS,  ORDINANCES AND GOVERNMENTAL
REGULATIONS PERMITTING THE TERMINATION OF THIS LEASE AS A RESULT OF THE DAMAGE
OR DESTRUCTION OF THE PROPERTY BY FIRE,  THE ELEMENTS,  CASUALTIES,  THEFTS,
RIOTS,  WARS OR OTHERWISE,  AND THE LESSOR SHALL IN NO EVENT BE ANSWERABLE OR
ACCOUNTABLE FOR ANY RISK OF LOSS OF OR DECREASE IN THE ENJOYMENT AND BENEFICIAL
USE OF THE PROPERTY AS A RESULT OF ANY SUCH EVENT.

                                 ARTICLE XXV.

     25.1  Subletting and Assignment.  The Lessee may, without the consent of
           -------------------------
the Lessor, sublease the Property or portion thereof to any Person, provided,
                                                                    --------
that no such sublease shall, in the reasonable opinion of the Lessor, materially
adversely affect any of the Lessor's interests, rights or remedies under the
Lease or the Lessor's title to the Property. No assignment, sublease or other
relinquishment of possession of the Property shall in any way discharge or
diminish any of the Lessee's obligations to the Lessor hereunder and the Lessee
shall remain directly and primarily liable under this Lease as to the Property,
or portion thereof, so assigned or sublet. Any sublease of the Property shall be
made subject to and subordinated to this Lease and to the rights of the Lessor
hereunder, shall expressly provide for termination at or prior to the earlier of
the applicable Expiration Date or other date of termination of this Lease unless
the Lessee shall

                                       40
<PAGE>

have purchased the Property pursuant to Article XX. No assignee or sublessee
                                        ----------
shall use the Property in a manner which is substantially different from the
manner in which the Property is used or intended for use by the Lessee or in any
manner not otherwise permitted under Section 8.2, without the prior written
                                     -----------
consent of the Lessor.

                                 ARTICLE XXVI.

     26.1  Estoppel Certificates.  At any time and from time to time upon not
less than twenty (20) days' prior request by the Lessor or the Lessee (the
"Requesting Party"), the other party (whichever party shall have received such
 ----------------
request, the "Certifying Party") shall furnish to the Requesting Party (but not
more than four times per year unless required to satisfy the requirements of any
sublessees and only to the extent that the required information has been
provided to the Certifying Party by the other party) a certificate signed by an
individual having the office of vice president or higher in the Certifying Party
certifying that this Lease is in full force and effect (or that this Lease is in
full force and effect as modified and setting forth the modifications); the
dates to which the Basic Rent and Supplemental Rent have been paid; to the best
knowledge of the signer of such certificate, whether or not the Requesting Party
is in default under any of its obligations hereunder (and, if so, the nature of
such alleged default); and such other matters under this Lease as the Requesting
Party may reasonably request. Any such certificate furnished pursuant to this
Article XXVI may be relied upon by the Requesting Party, and any existing or
------------
prospective mortgagee, purchaser or lender, and any accountant or auditor, of,
from or to the Requesting Party (or any Affiliate thereof).

                                ARTICLE XXVII.

     27.1  Right to Inspect.  During the Term, the Lessee shall upon reasonable
           ----------------
notice from the Lessor (except that no notice shall be required if a Lease Event
of Default has occurred and is continuing), permit the Lessor, the Agent and
their respective authorized representatives to inspect the Property during
normal business hours and so long as no Event of Default has occurred and is
continuing, such inspections shall be not more than once each quarter, provided
that such inspections shall not unreasonably interfere with the Lessee's
business operations at the Property, and provided, further that the Lessee may,
if it so chooses, be present during such inspections.

     27.2  No Waiver.  No failure by the Lessor or the Lessee to insist upon the
           ---------
strict performance of any term hereof or to exercise any right, power or remedy
upon a default hereunder, and no acceptance of full or partial payment of Rent
during the continuance of any such default, shall constitute a waiver of any
such default or of any such term. To the fullest extent permitted by law, no
waiver of any default shall affect or alter this Lease, and this Lease shall
continue in full force and effect with respect to any other then existing or
subsequent default.

                                ARTICLE XXVIII.

     28.1  Acceptance of Surrender.  No surrender to the Lessor of this Lease or
           -----------------------
of all or any portion of the Property or of any part thereof or of any interest
therein shall be valid or effective

                                       41
<PAGE>

unless agreed to and accepted in writing by the Lessor and, prior to the payment
or performance of all obligations under the Participation Agreement and
termination of the Commitments, the Agent, and no act by the Lessor or the Agent
or any representative or agent of the Lessor or the Agent, other than a written
acceptance, shall constitute an acceptance of any such surrender.

                                 ARTICLE XXIX.

     29.1  No Merger of Title.  There shall be no merger of this Lease or of the
           ------------------
leasehold estate created hereby by reason of the fact that the same Person may
acquire, own or hold, directly or indirectly, in whole or in part, (a) this
Lease or the leasehold estate created hereby or any interest in this Lease or
such leasehold estate, or (b) any estate of others in the Property created by
any sublease permitted under this Lease, except as may expressly be stated in a
written instrument duly executed and delivered by the appropriate Person.

--------

     WHEREAS, the Lessee desires to grant a deed of trust lien on its leasehold
interest in the Land Interest created by the Lease to the Trustee for the
benefit of the Lessor to secure the Obligations (as hereinafter defined) of the
Lessee;

     NOW, THEREFORE, in consideration of the premises and the mutual agreements
herein contained and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto agree as
follows:

     SECTION 1.  Definitions; Interpretation.  For purposes of this Lease
                 ---------------------------
Supplement, capitalized terms used herein and not otherwise defined herein shall
have the meanings assigned to them in Appendix 1 to the Master Lease, dated as

interpretation set forth in Appendix 1 to the Lease shall apply to this Lease
Supplement.

     SECTION 2.  Land Interest.  Attached hereto as Schedule 1 is the
                 -------------
description of a certain Land Interest.  Effective upon the execution and
delivery of this Lease Supplement by the Lessor and the Lessee, the Property

and conditions of the Lease, the Lessor hereby leases to the Lessee for the Term

the Lessee hereby
<PAGE>

agrees, expressly for the direct benefit of the Lessor, to lease from the Lessor
for the Term, the Lessor's interest in the Land Interest.

     SECTION 3.  Parties and Addresses.  The Lease is dated as of June 30, 2000,
                 ---------------------
between the Lessor, whose principal office is at 135 South LaSalle Street,
Chicago, Illinois 60603 and the Lessee, whose principal office is 48761 Kato

     SECTION 4.  Lease Term.  The term of the Lease (the "Term") shall begin on
                 ----------                               ----
the Lease Commencement Date and shall end on June 30, 2005 unless the Term is
renewed or earlier terminated in accordance with the provisions of the Lease.
The Lease contains two option periods of one year, which gives the Lessee the
right, subject to the terms thereof, to extend the term of the Lease to no later
than June 30, 2007.

     SECTION 5.  Ownership of the Property.

     (a) It is the intent of the parties hereto that: (i) the Lease constitutes
an "operating lease" pursuant to Statement of Financial Accounting Standards No.
13, as amended and interpreted, for purposes of the Lessee's financial
reporting, and (ii) for purposes of federal, state, and local income or
franchise taxes and for any other tax imposed on or measured by income, the
transaction contemplated hereby and by the Lease is a financing arrangement and
preserves ownership in the Property in the Lessee.  The parties shall take no
action inconsistent with such intention.  Nevertheless, the Lessee acknowledges
and agrees that neither the Agent, the Lessor nor any Participant has made any
representations or warranties to the Lessee concerning the tax, accounting or
legal characteristics of the Operative Documents and that the Lessee has
obtained and relied upon such tax, accounting and legal advice concerning the
Operative Documents as it deems appropriate.

     (b) Anything to the contrary in the Operative Documents notwithstanding,
the Lessor and the Lessee intend and agree that with respect to the nature of
the transactions evidenced by the Lease in the context of the exercise of
remedies under the Operative Documents, including, without limitation, in the
case of any insolvency or receivership proceedings or a petition under the
United States bankruptcy laws or any other applicable insolvency laws or statute
of the United States of America or any State or Commonwealth thereof or any
foreign country affecting the Lessee, the Lessor, or any Participant or any
enforcement or collection actions arising out of or relating to bankruptcy or
insolvency laws, (i) the transactions evidenced by the Lease shall be deemed to
be loans made by the Lessor and the Participants as unrelated third party
lenders to the Lessee secured by the Property, (ii) the obligations of the
Lessee under the Lease to pay Basic Rent, Supplemental Rent, Asset Termination
Value or Land Residual Value Guarantee Amount or the Improvements Residual Value
Guarantee Amount in connection with a purchase of the Property pursuant to the
Lease shall be treated as payments of interest on and principal of,
respectively, loans from the Lessor and the Participants to the Lessee, and
(iii) the Lease grants a security interest and mortgage or deed of trust or
lien, as the case may be, in the Property to the Lessor and assigned by the
Lessor to the Agent for the benefit of the Participants to secure the Lessee's
performance under and payment of all amounts under the Lease and the other
Operative Documents.

     (c) Specifically, without limiting the generality of subsections (a) and
                                                          -------------------
(b) of this Section 5, the parties hereto intend and agree that, for purposes of
---         ---------
filing federal, state and local returns, reports and other statements relating
to income or franchise taxes, or any other taxes imposed upon or measured by
income, (i) the Lessee shall be entitled to take any deduction, credit,
allowance or other reporting position consistent with its status as owner of the
Property; and (ii) neither the Lessor nor any Participant shall take an initial
position on its federal, state and local returns, reports and other statements
relating to income or franchise taxes that is inconsistent with the Lessee's
status as owner of the Property.

     (d)  If the transactions evidenced by this Agreement and the other
Operative Documents can no longer be treated as an operating lease pursuant to
GAAP for accounting purposes, all provisions in the Operative Documents limiting
the Lessee's obligation to pay the Asset Termination Value (including the
Remarketing Option) on the Expiration Date shall no longer apply.  If any such
change in accounting treatment shall occur, the Lessee, the Lessor, the Agent
and the Participants shall negotiate in good faith to enter into such amendments
to the Operative Documents as may be reasonably necessary or desirable to
reflect the foregoing.

     (e)  In the event that, after the date hereof, the UCC as enacted and in
effect in any applicable jurisdiction shall be revised or amended, the Lessee,
the Lessor, the Agent and the Participants shall negotiate in good faith to
enter into such amendments to the Operative Documents as may be reasonably
necessary or desirable to reflect or otherwise address such revisions or
amendments.

Section 5, in order to secure the Lessee's obligation to pay Basic Rent,
---------
Supplemental Rent, Asset Termination Value, the Residual Value Guarantee Amount,
the Purchase Option Price, the Partial Purchase Option Price and all other

Commercial Code), a fixture filing and a real property mortgage or deed of trust

Uniform Commercial Code; and (iv) notifications to Persons holding such
property, and acknowledgments, receipts or confirmations from financial
intermediaries, bankers or agents (as applicable) of the Lessee shall be deemed

documents, financing statements, mortgages and deeds of trust as may be
necessary to ensure that, if the Lease were deemed to create a security interest

     WHEREAS, the Lessee desires to grant a deed of trust lien on its leasehold
interest in the Improvements created by the Lease to the Trustee for the benefit
of the Lessor to secure the Obligations (as hereinafter defined) of the Lessee;

     NOW, THEREFORE, in consideration of the premises and the mutual agreements
herein contained and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto agree as
follows:

     SECTION 1.  Definitions; Interpretation.  For purposes of this Lease
                 ---------------------------
Supplement, capitalized terms used herein and not otherwise defined herein shall
have the meanings assigned to them in Appendix 1 to the Master Lease, dated as

Effective upon the execution and delivery of this Lease Supplement by the Lessor

     SECTION 4.  Lease Term.  The term of the Lease (the "Term") shall begin on
                 ----------                               ----
the Lease Commencement Date and shall end on June 30, 2005 unless the Term is
renewed or earlier terminated in accordance with the provisions of the Lease.
The Lease contains two option periods of one year, which gives the Lessee the
right, subject to the terms thereof, to extend the term of the Lease to no later
than June 30, 2007.

     SECTION 5.  Ownership of the Property.

     (a) It is the intent of the parties hereto that: (i) the Lease constitutes
an "operating lease" pursuant to Statement of Financial Accounting Standards No.
13, as amended and interpreted, for purposes of the Lessee's financial
reporting, and (ii) for purposes of federal, state, and local income or
franchise taxes and for any other tax imposed on or measured by income, the
transaction contemplated hereby and by the Lease is a financing arrangement and
preserves ownership in the Property in the Lessee. The parties shall take no
action inconsistent with such intention. Nevertheless, the Lessee acknowledges
and agrees that neither the Agent, the Lessor nor any Participant has made any
representations or warranties to the Lessee concerning the tax, accounting or
legal characteristics of the Operative Documents and that the Lessee has
obtained and relied upon such tax, accounting and legal advice concerning the
Operative Documents as it deems appropriate.

     (b) Anything to the contrary in the Operative Documents notwithstanding,
the Lessor and the Lessee intend and agree that with respect to the nature of
the transactions evidenced by the Lease in the context of the exercise of
remedies under the Operative Documents, including, without limitation, in the
case of any insolvency or receivership proceedings or a petition under the
United States bankruptcy laws or any other applicable insolvency laws or statute
of the United States of America or any State or Commonwealth thereof or any
foreign country affecting the Lessee, the Lessor, or any Participant or any
enforcement or collection actions arising out of or relating to bankruptcy or
insolvency laws, (i) the transactions evidenced by the Lease shall be deemed to
be loans made by the Lessor and the Participants as unrelated third party
lenders to the Lessee secured by the Property, (ii) the obligations of the
Lessee under the Lease to pay Basic Rent, Supplemental Rent, Asset Termination
Value or Land Residual Value Guarantee Amount or the Improvements Residual Value
Guarantee Amount in connection with a purchase of the Property pursuant to the
Lease shall be treated as payments of interest on and principal of,
respectively, loans from the Lessor and the Participants to the Lessee, and
(iii) the Lease grants a security interest and mortgage or deed of trust or
lien, as the case may be, in the Property to the Lessor and assigned by the
Lessor to the Agent for the benefit of the Participants to secure the Lessee's
performance under and payment of all amounts under the Lease and the other
Operative Documents.

     (c) Specifically, without limiting the generality of subsections (a) and

---         ---------
filing federal, state and local returns, reports and other statements relating
to income or franchise taxes, or any other taxes imposed upon or measured by
income, (i) the Lessee shall be entitled to take any deduction, credit,
allowance or other reporting position consistent with its status as owner of the
Property; and (ii) neither the Lessor nor any Participant shall take an initial
position on its federal, state and local returns, reports and other statements
relating to income or franchise taxes that is inconsistent with the Lessee's
status as owner of the Property.

     (d) If the transactions evidenced by this Agreement and the other Operative
Documents can no longer be treated as an operating lease pursuant to GAAP for
accounting purposes, all provisions in the Operative Documents limiting the
Lessee's obligation to pay the Asset Termination Value (including the
Remarketing Option) on the Expiration Date shall no longer apply.  If any such
change in accounting treatment shall occur, the Lessee, the Lessor, the Agent
and the Participants shall negotiate in good faith to enter into such amendments
to the Operative Documents as may be reasonably necessary or desirable to
reflect the foregoing.

     (e) In the event that, after the date hereof, the UCC as enacted and in
effect in any applicable jurisdiction shall be revised or amended, the Lessee,
the Lessor, the Agent and the Participants shall negotiate in good faith to
enter into such amendments to the Operative Documents as may be reasonably
necessary or desirable to reflect or otherwise address such revisions or
amendments.

Commercial Code), a fixture filing and a real property mortgage or deed of trust

(iv) notifications to Persons holding such property, and acknowledgments,
receipts or confirmations from financial intermediaries, bankers or agents (as
applicable) of the Lessee shall be deemed to have been given for the purpose of

Lessee shall, to the extent consistent with the Lease, take such actions and
execute, deliver, file and record such other documents, financing statements,
mortgages and deeds of trust as may be necessary to ensure that, if the Lease
were deemed to create a security interest in the Property in accordance with

interest of first priority under Applicable Law and will be maintained as such
