Following the execution and delivery of a Construction Agency Agreement
Supplement, in the form attached as EXHIBIT A, such Construction Agency
Agreement Supplement shall constitute a part of this Agreement.

                                   ARTICLE 3

                                THE IMPROVEMENTS

        3.1    CONSTRUCTION. The Construction Agent shall cause the Improvements
to be constructed and equipped in compliance with all Legal Requirements and
Insurance Requirements.

        3.2    AMENDMENTS; MODIFICATIONS.

               (a)    The Construction Agent may at any time revise, amend or
modify (i) the Plans and Specifications without the consent of the Lessor;
provided, that any such amendment to the Plans and Specifications does not (x)
result in the Completion Date of the Improvements occurring on or after the
Commitment Termination Date or (y) result in the cost to complete any
Improvements subject to such amendment exceeding either (1) the Available
Commitments or (2) 110% of the Projected Completion Value with respect to such
Improvements, and (ii) the Budget; provided, that such revisions, amendments or
modifications to the Budget do not (x) result in any increase in the Project
Costs greater than either (1) the sum of the then Available Commitments or (2)
110% of the Projected Completion Value with respect to the Improvements or (y)
cause the Budget to fail to be In Balance.

               (b)    The Construction Agent agrees that it will not implement
any revision, amendment or modification to the Plans and Specifications if the
aggregate effect of such revision, amendment or modification would be to reduce
the fair market value, utility or residual value of any Property by more than a
de minimis amount.

        3.3    CASUALTY, CONDEMNATION AND FORCE MAJEURE EVENTS. If at any time
prior to the Completion Date for any Property there occurs a Casualty or a Force
Majeure Event or the Lessor or the Construction Agent receives notice of a
Condemnation, then, except as otherwise provided in Article XV and XVI of the
Lease, in each case the Construction Agent shall in accordance herewith promptly
and diligently complete the construction of the Improvements in accordance with
the applicable Plans and Specifications and in compliance with the terms hereof,
and cause the Completion Date for such Property to occur on or prior to the
Commitment Termination Date. During the Construction Period, the Construction
Agent shall be entitled to negotiate, prosecute, adjust or appeal any claim for
any award, compensation or insurance payment on account of any Condemnation or
Casualty, subject to the provisions of SECTION 6.1(d). The Lessor and the Agent
shall consult the Construction Agent in connection with the foregoing.

                                   ARTICLE 4

                                PAYMENT OF FUNDS


                                       6.
<PAGE>   10

        4.1    RIGHT TO RECEIVE PROJECT COSTS.

               (a)    In connection with the acquisition of the Land and during
the course of the construction of the Improvements on the Land, the Construction
Agent may request that the Lessor advance funds for the payment of Project
Costs, and the Lessor will comply with such request to the extent provided for
under the Participation Agreement. The Construction Agent and the Lessor
acknowledge and agree that the Construction Agent's right to request funds and
the Lessor's obligation to advance funds for the payment of Project Costs is
subject in all respects to the terms and conditions of the Participation
Agreement and each of the other Operative Agreements. The Construction Agent
agrees that it cannot incur Project Costs unless the Lessee, as Construction
Agent, has complied with the applicable provisions of Section 5 of the
Participation Agreement.

               (b)    The proceeds of any funds made available to the Lessor to
pay Project Costs shall be made available to the Construction Agent in
accordance with the Requisition relating thereto and the terms of the
Participation Agreement. The Construction Agent will use such proceeds only to
pay Project Costs set forth in the Requisition relating to such funds.

        4.2    COST OVERRUNS.

               (a)    In the event that the Construction Agent determines that
the Available Commitments will be insufficient to complete construction on any
or all Properties (a "Cost Overrun"), it shall promptly notify the Lessor and
the Agent, which notice shall indicate the additional funds the Construction
Agent considers necessary to complete such construction. The Construction Agent
may (i) request the Holders and the Lenders to increase their Commitments to
enable it to complete construction but the Holders and the Lenders shall be
under no obligation to agree to such request, or (ii) exercise its Purchase
Option under Section 20.1 of the Lease and purchase such Property and make the
payments required therein.

               (b)    If a Cost Overrun shall occur or be likely to occur, such
event shall constitute a Construction Agency Agreement Event of Default
hereunder and, if the Construction Agent is not exercising its Purchase Option
under the Lease, the Lessor and the Participants may elect to:

                      (i)    (A)    terminate their Commitments as provided in
SECTION 5.1 and order the Construction Agent to cease construction as of any
date, if any, specified by the Lessor; and

                             (B)    except in the case of clause (i)(C), require
the Construction Agent to:

                                    (1)    return possession of the Properties
to the Lessor or remarket the Lessor's interest in the Properties as provided in
Section 21.1(b) of the Lease; and


                                       7.
<PAGE>   11

                                    (2)    pay the Construction Period Maximum
Recourse Amount for all Properties to the Lessor, in which event the Lessor
shall proceed under SECTIONS 5.3(B) and 5.5; or

                             (C)    if such Cost Overrun constitutes a Full
Recourse Construction Period Event of Default, the Lessor shall have all of its
rights and remedies available under the Operative Agreements (including under
Section 17.2 of the Lease), subject, as to the Lessee's recourse liability, to
the limits set forth in Section 17.2 of the Lease, and, if so required, the
Construction Agent, as Lessee, shall make the payments set forth therein; or

                      (ii)   increase the aggregate Commitments by an amount
sufficient to complete such construction, with the consent of the Construction
Agent, and upon such increase order the Construction Agent to continue
diligently to construct the Improvements on such Property in accordance with
this Agreement until the Completion thereof.

               (c)    To the extent that the Lessor has not elected to terminate
this Agreement pursuant to SECTION 5.1 or increase the Commitments pursuant to
SECTION 4.2(B)(II) and the Lessee has not exercised its Purchase Option, the
Construction Agent shall continue diligently to construct the Improvements in
accordance with this Agreement until the Completion thereof and shall pay
prepaid rent to the Lessor to fund, subject to a limit of the Construction
Period Maximum Recourse Amount, the costs of such construction if Advances are
no longer available under the Participation Agreement.

                                EVENTS OF DEFAULT

        5.1    EVENTS OF DEFAULT. If any one or more of the following events
(each a "Construction Agency Agreement Event of Default") shall occur:

               (a)    the Construction Agent fails to apply any funds paid by
the Lessor to the Construction Agent for the acquisition of any Property and the
construction of the Improvements thereon or the payment of Project Costs; or

               (b)    the Construction Agent shall cause or permit any
Improvements to be constructed and equipped in a manner which (i) violates in
any material respect any applicable law or violates any Insurance Requirement or
(ii) deviates from the Plans and Specifications and such deviation is not
permitted under SECTION 3.2(a) and has not been consented to by the Lessor and
the Agent; or

               (c)    a Cost Overrun occurs, or shall be likely to occur, as
contemplated by SECTION 4.2; or

               (d)    the Construction Agent shall (i) admit in writing its
inability to pay its debts generally as they become due, (ii) file a petition
under the United States bankruptcy laws or any other applicable insolvency law
or statute of the United States of America or any State or


                                       8.

Commonwealth thereof, (iii) make a general assignment for the benefit of its
creditors, (iv) consent to the appointment of a receiver of itself or the whole
or any substantial part of its property, (v) fail to cause the discharge of any
custodian, trustee or receiver appointed for Construction Agent or the whole or
a substantial part of its property within sixty (60) days after such
appointment, or (vi) file a petition or answer seeking or consenting to
reorganization under the United States bankruptcy laws or any other applicable
insolvency law or statute of the United States of America or any State or
Commonwealth thereof; or

               (e)    insolvency proceedings or a petition under the United
States bankruptcy laws or any other applicable insolvency law or statute of the
United States of America or any State or Commonwealth thereof shall be filed
against the Construction Agent and not dismissed within sixty (60) days from the
date of its filing, or a court of competent jurisdiction shall enter an order or
decree appointing, without the consent of Construction Agent, a receiver of
Construction Agent or the whole or a substantial part of its property, and such
order or decree shall not be vacated or set aside within sixty (60) days from
the date of the entry thereof; or

               (f)    the Construction Agent shall fail to perform or observe
any other covenant or agreement to be performed or observed by it under this
Agreement other than as specifically referred to in this SECTION 5.1 and such
failure shall continue for a period of thirty (30) days after receipt by the
Construction Agent of a written notice from the Lessor specifying such failure
and requiring it to be remedied; provided, that, notwithstanding language to the
contrary in this clause (f), any failure by the Construction Agent to perform
its obligations under SECTION 2.7(d) shall result in a Construction Agency
Agreement Event of Default upon the continuation of such failure for a period of
fifteen (15) days thereafter; or

               (g)    any amount payable as Supplemental Rent shall not be paid
when due because of the limitation in the Operative Agreements on the payment of
any such amounts during the Construction Period to the Construction Period
Maximum Recourse Amount, subject to the maximum limitation on damages as a
result of a Construction Agency Agreement Event of Default under this clause (g)
set forth in SECTIONS 5.3(b) and 5.4;

               (h)    the Construction Agent shall fail to maintain insurance
required by ARTICLE VI; or

               (i)    the Budget shall fail to be In Balance; or

               (j)    a Force Majeure Event shall occur;

then, in any such event, and subject to SECTION 5.4, the Lessor may, in addition
to the other rights and remedies provided for in this Article, terminate this
Agreement and the Commitments by giving the Construction Agent notice of such
termination and upon the receipt of such notice, this Agreement shall terminate
and all rights and obligations of the Construction Agent and the Lessor under
this Agreement shall cease except to the extent set forth in this ARTICLE V and
in SECTION 4.2. The Construction Agent shall pay all costs and expenses incurred
by or on behalf of the Lessor, including reasonable fees and expenses of
counsel, as a result of any Event of Default hereunder.

        5.2    SURVIVAL. The termination of this Agreement pursuant to SECTION
5.1 shall in no event relieve the Construction Agent of its liabilities and
obligations hereunder which accrued prior to such termination, or which arise as
a result of such termination, all of which shall survive any such termination.

        5.3    REMEDIES.

               (a)    If a Construction Agency Agreement Event of Default shall
have occurred and be continuing and such Event of Default shall constitute a
Full Recourse Construction Period Event of Default, the Lessor shall have all
rights and remedies available under the Operative Agreements (including under
Section 17.2 of the Lease), subject, as to the Lessee's recourse liability, to
the limits set forth in Section 17.2(a)(i)-(iii) of the Lease.

               (b)    If a Construction Agency Agreement Event of Default shall
have occurred and be continuing and the same does not constitute a Full Recourse
Construction Period Event of Default or a Construction Agency Agreement Event of
Default shall have occurred under SECTION 5.1(G) or 5.1(J), the Lessor shall
have the right to require the Construction Agent to relinquish its interest in
each of the Properties to the Lessor and to pay to the Lessor as liquidated
damages and not as a penalty, the Construction Period Maximum Recourse Amount.
Under such circumstances, the Construction Agent shall convey to the Lessor its
interest in and possession of the Properties free and clear of all Liens (other
than Lessor Liens and Permitted Exceptions) and in compliance with all
Environmental Laws accompanied by an affidavit to the Lessor and the Agent to
such effect and appropriate statements of termination.

               (c)    No failure to exercise and no delay in exercising, on the
part of the Lessor or the Agent, any right, remedy, power or privilege under
this Agreement or under the other Operative Agreement shall operate as a waiver
thereof, nor shall any single or partial exercise of any right, remedy, power or
privilege under this Agreement preclude any other or further exercise thereof or
the exercise of any other right, remedy, power or privilege. The rights,
remedies, powers and privileges provided in this Agreement and in the other
Operative Agreements are cumulative and not exclusive of any rights, remedies,
powers and privileges provided by law.

               (d)    Notwithstanding the foregoing, the Construction Agent
shall have the right to cure a Construction Agency Agreement Event of Default by
purchasing the Properties for the Lease Balance.

        5.4    LIMITATION ON CONSTRUCTION AGENT'S RECOURSE LIABILITY.
Notwithstanding anything contained herein or in any other Operative Agreement to
the contrary, upon the occurrence and during the continuance of a Construction
Agency Agreement Event of Default which does not constitute a Full Recourse
Construction Period Event of Default or which is a Construction Agency Agreement
Event of Default under clause (g) or (j) of SECTION 5.1, so long as the
Construction Agent complies with its obligations set forth in SECTIONS 5.3(b)
and 5.5, the aggregate maximum recourse liability of the Construction Agent to
the Lessor in respect of such Events of Default shall be limited to the
Construction Period Maximum Recourse Amount.

        5.5    CERTAIN ONGOING OBLIGATIONS. Following the occurrence of (a) a
Construction Agency Agreement Event of Default, unless the Construction Agent
has exercised its right to cure pursuant to SECTION 5.3(d), and (b) the actions
contemplated by SECTION 5.3(b), the Construction Agent will, if so requested by
Lessor, at the sole expense of the Construction Agent, use its commercial best
efforts, as non-exclusive agent of the Lessor, to market the Properties to third
party purchasers in accordance with Section 21.1(b) of the Lease.

                                    ARTICLE 6

                                    INSURANCE

        The Construction Agent shall procure insurance during the Construction
Period in accordance with the following provisions:

        6.1    PUBLIC LIABILITY INSURANCE.

               (a)    CONSTRUCTION AGENT RESPONSIBLE. During the Construction
Period, the Construction Agent shall procure and carry, at the Construction
Agent's sole cost and expense, the liability insurance described in Section 14.1
of the Lease, subject to such deductibles as are set forth on each Construction
Agency Agreement Supplement. The Construction Agent acknowledges and agrees that
each Property is in its control and possession during the Construction Period,
it is responsible as Construction Agent for the acts and omissions of its
subcontractors and agents and other Lessee Persons and that it has agreed to
maintain each Property free from injury and mishap to third Persons.

               (b)    HAZARD AND OTHER INSURANCE. During the Construction
Period, the Construction Agent shall also maintain and keep in force a policy or
policies of "all risk" insurance with respect to each Property, including
builder's risk insurance, subject to such deductibles as are set forth on each
Construction Agency Agreement Supplement, insuring the Lessor's interest in all
Improvements and Equipment, written on a replacement cost basis. The premium for
such coverage shall be paid with the proceeds of an Advance or, if paid by the
Construction Agent, reimbursed with such proceeds. In addition, the reduction in
any recovery pursuant to any deductible applicable to such policy shall be paid
with the proceeds of an Advance.

               (c)    COVERAGE. The insurance required to be obtained by the
Construction Agent under SECTIONS 6.1(a) and (b) is described on each
Construction Agency Agreement Supplement and may be carried under blanket
policies maintained by or on behalf of the Construction Agent so long as such
policies otherwise comply with the provisions of this SECTION 6.1. The insurance
required by SECTIONS 6.1(a) and (b) shall provide in the policy or by special
endorsement that:

                      (i)    in the case of insurance required by SECTION
6.1(a), the Lessor, the Holders, the Lenders and the Agent are included as
additional insureds as their interests may appear and, in the case of insurance
required by SECTION 6.1(b), the Agent, for the benefit of the Participants,
shall be named as loss payee;


                                      11.
<PAGE>   15

                      (ii)   such insurance shall be primary without right of
contribution of any other insurance carried by or on behalf of the Lessor, the
Holders, the Lenders or the Agent and shall provide that no such Person shall
have any obligation or liability for payment of premiums;

                      (iii)  if the insurers cancel such insurance for any
reason whatsoever or any materially adverse change is made in policy terms or
conditions, or if such insurance is allowed to lapse for nonpayment of premium,
such cancellation, change or lapse shall not be effective as to the Lessor, the
Holders, the Lenders and the Agent for thirty (30) days after receipt by the
Lessor, the Holders, the Lenders and the Agent, respectively, of written notice
from such insurers of such cancellation, change or lapse;

                      (iv)   such policy will not be invalidated should the
Construction Agent 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 Holders, the Lenders and the Agent, 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 Construction
Agent or any other Person having any interest in any Property and a so-called
"Waiver of Subrogation Clause." The Construction Agent hereby waives any and all
such rights against the Lessor, the Holders, the Lenders and the Agent to the
extent of payments made under such policies;

                      (v)    all such insurance policies required by SECTION
6.1(b) shall include a "New York" or standard form mortgagee endorsement in
favor of the Agent and 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;

                      (vi)   all insurance coverages required pursuant to this
Article VI shall be obtained from insurance companies which carry a current
rating by the A.M. Best Company of at least "A" and a financial rating of at
least "8."

                      (vii)  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 SECTION 6.1 except that the Lessor may carry
separate liability insurance (at its sole cost) so long as (i) the Construction
Agent'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 Construction Agent's policy and (ii) each such
insurance policy will not cause the Construction Agent's insurance required
under this SECTION 6.1 to be subject to a coinsurance exception of any kind; and

                      (viii) upon thirty (30) days' notice from the Lessor and
the Agent the Construction Agent shall provide evidence of insurance obtained
pursuant hereto, in the form of a broker's certificate and certificates for
renewal and replacement policies.

               (d)    ADJUSTMENT OF LOSSES. Losses, if any, with respect to any
Property under any property damage policies required to be carried under SECTION
6.1(b) shall be adjusted with


                                      12.
<PAGE>   16

the insurance companies, including the filing of appropriate proceedings by the
Construction Agent if the Construction Agent is required by the Operative
Agreements to, or has agreed to, repair the damage to the Improvements, unless a
Lease Event of Default shall have occurred and be continuing, in which case
losses shall be adjusted by the Lessor. Losses shall also be adjusted by the
Lessor in circumstances where the Construction Agent is not required to, and has
not agreed to, repair the damage to the Improvements, unless the Construction
Agent has purchased such Property pursuant to the terms of the Operative
Agreements. The party which shall be entitled to adjust losses may appear in any
proceeding or action to negotiate, prosecute, adjust or appeal any claim for any
award, compensation or insurance payment on account of any Casualty or
Condemnation and shall pay all expenses thereof. At such party's reasonable
request, and at the Construction Agent's sole cost and expense, the Construction
Agent, the Lessor, the Holders and the Lenders, as the case may be, shall
participate in any such proceeding, action, negotiation, prosecution or
adjustment. The parties hereto agree that this Agreement shall control the
rights of the parties hereto in and to any such award, compensation or insurance
payment.

               (e)    APPLICATION OF INSURANCE PROCEEDS. All proceeds of
insurance maintained pursuant to SECTION 6.1(b) on account of any damage to or
destruction of any Property or any part thereof shall be paid over to the Lessor
or as it may direct; provided, that if Lessor has not elected to terminate the
Lease pursuant to Section 16.1 thereof and (i) if no Lease Event of Default
shall have occurred and be continuing and, so long as the Construction Agent is
diligently repairing the damage to such Property caused by the applicable
Casualty, all such proceeds shall be disbursed to the Construction Agent to
effect the repair of such Improvements or such Equipment, and (ii) (A) if the
subject Casualty did not arise from or constitute a Full Recourse Construction
Period Event of Default and (B) no other Lease Event of Default has occurred and
is continuing, Lessor shall look only to such insurance proceeds and the
proceeds of the sale or transfer of such Property in order to effect such
repair.

                                   ARTICLE 7

                                 LESSOR'S RIGHTS

        7.1    ASSIGNMENT OF THE LESSOR'S RIGHTS. Subject to the terms of the
Contract Assignment made by the Lessor in favor of the Agent, Lessee and Lessor
hereby acknowledge and agree that the rights and powers of the Lessor under this
Agreement have been assigned to, and may be exercised by, the Agent.

        7.2    LESSOR'S RIGHT TO CURE CONSTRUCTION AGENT'S DEFAULTS. Upon
written notice to the Construction Agent, except in emergencies, the Lessor,
without waiving or releasing any obligation of the Construction Agent or an
Event of Default, may (but shall be under no obligation to) remedy any Event of
Default for the account of and at the sole cost and expense of the Construction
Agent (subject to the limitations on the Construction Agent's recourse liability
set forth in SECTION 5.4 and Section 17.2 of the Lease). All out-of-pocket costs
and expenses so incurred (including reasonable fees and expenses of counsel),
together with interest thereon at the Overdue Rate from the date on which such
sums or expenses are paid by the Lessor, shall be paid by the Construction Agent
to the Lessor on demand.
