      LEASE, dated as of August 22, 1997, between TEN HANOVER LLC ("Landlord"),
a New York limited liability company having its principal office c/o The Witkoff
Group LLC, 156 William Street, New York, New York 10038, and THE GOLDMAN SACHS
GROUP, L.P. ("Tenant"), a Delaware limited partnership having its principal
office at 85 Broad Street, New York, New York 10004, Attention: General Services
Department.

                                   WITNESSETH:

      That in consideration of the mutual agreements herein contained, Landlord
and Tenant hereby agree and covenant to and with each other as follows:

      1. Leased Premises; Term of Lease

            1.1 Leased Premises

            Landlord leases to Tenant, and Tenant rents from Landlord, subject
to the Permitted Encumbrances, the land located in the City, County and State of
New York more particularly described on Exhibit A hereto (the "Land"),

            TOGETHER WITH (i) all Improvements (excluding any thereof which
      pursuant to the final paragraph of this Section 1.1 are not Landlord's
      property), and (ii) all personal property owned by Landlord now or
      hereafter attached to or used in connection with the Improvements,

            TOGETHER WITH all right, title and interest, if any, of Landlord in
      and to:

                        (a) any strips and gores of land adjoining the Land on
      any side thereof; 

                        (b) any land lying in the bed of any street or avenue
      abutting the Land, to the center line thereof; and

                        (c) any easements or other rights in adjoining property
      enuring to Landlord by reason of ownership of the Land;

all of the foregoing (together with any Improvements excluded from clause (i)
above) are collectively called the "Leased Premises".

            The Land and the Improvements are collectively called the "Project".
The term "Permitted Encumbrances" shall refer to the matters listed on Exhibit C
hereto. Simultaneously with the execution of this Lease, Landlord and Tenant are
executing an Initial Improvements Agreement of even date herewith (the "Initial
Improvements Agreement") relating to certain work to be done to prepare the
Leased Premises for occupancy by Tenant.

            The term "Improvements" shall mean all buildings, structures,
fixtures, equipment and improvements now or hereafter located on, or attached to
or appurtenant to, the Land or to other Improvements, including any thereof
installed (i) as Base Building Upgrade Work (as such

<PAGE>   12

term is defined in the Initial Improvements Agreement) or Fit-Out Work (as such
term is defined in the Initial Improvements Agreement) pursuant to the Initial
Improvements Agreement, or (ii) by Tenant pursuant to Article 6; provided, that
the term "Improvements" shall not include any furniture, furnishings, trade
fixtures or business equipment furnished, installed or placed in the
Improvements by Tenant at Tenant's sole cost and expense.

            Except as otherwise provided in the next paragraph, all Improvements
shall be (or if hereafter installed shall upon installation become) the property
of Landlord, a part of the Leased Premises and subject to this Lease.
Notwithstanding the provisions of Article 6, Tenant shall not remove from the
Leased Premises

            (i) any Improvements constituting Base Building Upgrade Work, or

            (ii) any Improvements constituting Fit-Out Work paid for by Landlord

unless (x) such removal is required by Legal Requirements, or (y) Tenant
replaces the Improvements so removed with other Improvements of substantially
equal value.

            All Improvements constituting Fit-Out Work paid for by Tenant shall
remain the property of Tenant, subject to removal by Tenant subject to the
provisions of Article 6; provided, that unless and until so removed, the same
shall nonetheless constitute Improvements for all purposes under this Lease. Any
such Improvements that shall not have been so removed shall, upon the expiration
or sooner termination of this Lease, become the property of Landlord.

            1.2 Term.

            Except as otherwise provided in Section 1.3, the term of this Lease
shall commence on the Possession Date (as such term is defined in the Initial
Improvements Agreement) and, unless sooner terminated pursuant to law or
pursuant to any of the terms of this Lease, shall expire at 11:59 p.m. on June
30, 2018 (the "Expiration Date"). The term of this Lease is referred to herein
as the "Term".

            1.3 Stephaneze Premises.

            (a) Landlord represents and warrants to Tenant that, as of the date
of this Lease, the Leased Premises are vacant and free of any occupancy or
tenancy or right thereto, other than the occupancy or tenancy by Stephaneze
("Stephaneze") of a portion of the Leased Premises (the "Stephaneze Premises"),
and that Landlord has commenced a summary proceeding against Stephaneze seeking
to recover possession of the Stephaneze Premises, and has furnished Tenant with
copies of all material pleading and material motion papers filed or served by
any party thereto. Landlord shall diligently prosecute such summary proceeding
and if such summary proceeding is dismissed or terminated without Landlord
having recovered possession of the Stephaneze Premises, then Landlord shall take
such further action as may be available to Landlord to recover possession of the
Stephaneze Premises.


                                       -2-
<PAGE>   13

            Promptly after recovering possession of the Stephaneze Premises,
Owner shall (i) perform and complete any Asbestos Removal Work, Refireproofing
Work, and/or Demolition Work (as such terms are defined in the Initial
Improvement Agreement), that may be required under the provisions of the Initial
Improvement Agreement with respect to the Stephaneze Premises, and (ii) notify
Tenant that the foregoing has been performed and completed and, prior to or
together with such notice, furnish Tenant with one or more Forms ACP-5
evidencing the removal from the Stephaneze Premises of all asbestos and
asbestos-containing material.

            The term of the Lease with respect to the Stephaneze Premises shall
commence on (and the term "Leased Premises" shall not include the Stephaneze
Premises until) the Stephaneze Possession Date. The term "Stephaneze Possession
Date" shall mean the last of

                              (x) the Possession Date,

                              (y) the date on which Landlord recovers possession
                  of the Stephaneze Premises,

                              (z) the date on which (i) all Asbestos Removal
                  Work, Refireproofing Work and Demolition Work throughout the
                  Stephaneze Premises shall have been completed, (ii) Tenant
                  shall have been furnished with or obtained one or more Forms
                  ACP-5 evidencing the removal from the Stephaneze Premises of
                  all asbestos and asbestos-containing material, and (iii)
                  Tenant shall have received the Stephaneze Completion Notice,

or, if Tenant shall so elect, such earlier date (not earlier than the later of
the Possession Date or the date 30 days after the date on which Landlord
recovers possession of the Stephaneze Premises) as Tenant shall elect by notice
to Landlord.

            If the Stephaneze Possession Date does not occur by the later of the
Possession Date or October 15, 1997, then Tenant shall be entitled to a credit
against the Basic Rent during the 12 month period beginning on the Rent
Commencement Date equal to $347,000; one-twelfth of such credit shall be applied
against each of the 12 monthly installments of Basic Rent during such 12 month
period. If the Stephaneze Possession Date does not occur by the first or any
later anniversary of October 15, 1997, then Tenant shall be entitled to a credit
against the Basic Rent during the 12 month period beginning with the first or
such later anniversary of the Rent Commencement Date equal to $347,000; one
twelfth of such credit shall be applied against each of the 12 monthly
installments of Basic Rent during such 12 month period. The preceding sentence
may be applied repeatedly, so long as Landlord's inability to deliver vacant
possession of the Stephaneze Premises by an anniversary of October 15, 1997
continues.

            This Section 1.3(a) shall be an express provision to the contrary
for purposes of Section 223-a of the New York Real Property Law and any other
law of like import now or hereafter in effect.

            (b) The following provisions of this Section 1.3(b) shall be
applicable until the Stephaneze Possession Date:

            (i)   There shall be no direct access between the Stephaneze
                  Premises and the Building (i.e., all access to or from the
                  Stephaneze Premises shall be from the street only).

            (ii)  Tenant shall not be required to furnish any services or
                  utilities to the Stephaneze Premises. If and to the extent
                  that the electricity, water, sewer, gas and telephone lines
                  currently serving the Stephaneze Premises run through the
                  Leased Premises, Tenant shall permit the same to remain;
                  provided, that Tenant shall have the right

                        (A)   to relocate such lines at Tenant's expense;
                              provided, that (i) any such relocation shall be
                              performed only at times other than during the
                              regular business hours of Stephaneze, and (ii) no
                              such relocation shall be performed prior to the
                              earlier of (1) October 15, 1997, or (2) the date
                              on which Landlord recovers possession of the
                              Stephaneze Premises (such earlier date being
                              herein called the "Stephaneze Restriction Date"),
                              and

                        (B)   to shut down such lines or otherwise to interrupt,
                              stop, suspend or curtail the delivery of services
                              through such lines whenever and for so long as may
                              be reasonably necessary by reason of damage to
                              such lines, accidents, or any testing,
                              maintenance, repairs, replacements, alterations,
                              additions or other work being undertaken by
                              Tenant, or by reason of any other cause beyond
                              Tenant's reasonable control; provided, that,
                              except in case of emergency, or reasonably
                              foreseeable or actual criminal liability of
                              Tenant, damage to such lines, accident or any
                              other cause beyond Tenant's reasonable control,
                              Tenant (i) shall not shut down such lines or
                              otherwise interrupt stop, suspend or curtail the
                              delivery of services through such lines prior to
                              the Stephaneze Restriction Date, and (ii) shall
                              use reasonable efforts to minimize interference
                              with the ordinary conduct of the business of
                              Stephaneze.

                  Provided that Tenant complies with the provisions of this
                  Section 1.3(b), Tenant shall have no liability to Landlord or
                  any Occupant of the Stephaneze Premises for or on account of
                  any shutdown of such lines or any interruption, stoppage,
                  suspension or curtailment of service through such lines for
                  any reason. In case of any damage to such lines, Tenant shall,
                  with reasonable promptness and diligence, immediately after
                  Tenant becomes aware of such damage, repair such damage (at
                  Landlord's

                  expense, unless such damage shall have arisen from any act,
                  omission, negligence or intentional misconduct of Tenant). All
                  electricity, gas and water and sewer service to the Stephaneze
                  Premises shall be separately metered, and the charges therefor
                  shall be paid by Landlord directly to the public or municipal
                  utility supplier.

            (iii) If the term of this Lease shall not have commenced with
                  respect to the Stephaneze Premises on or before March 1, 1998
                  then thereafter until the Stephaneze Possession Date: (A)
                  Landlord shall keep (or cause to be kept) all portions of the
                  Stephaneze Premises visible from without the Stephaneze
                  Premises in a well-maintained, clean and attractive condition;
                  (B) Landlord shall exterminate (or cause to be exterminated)
                  the Stephaneze Premises as necessary to keep the Stephaneze
                  Premises free of vermin; and (C) Landlord shall clean and
                  maintain (or cause to be cleaned and maintained) the exterior
                  surface of the exterior walls of the Stephaneze Premises,
                  including any and all glass located thereon.

            (iv)  Landlord shall make (or cause to be made) all repairs and
                  replacements in and to the Stephaneze Premises if the failure
                  to make such repair or replacement would result in an adverse
                  effect on the use, occupancy or appearance of the Leased
                  Premises and the need for such repair or replacement is not
                  the result of any act, omission, negligence or intentional
                  misconduct of Tenant (in which latter event such repair or
                  replacement shall be performed by Tenant). Landlord, at
                  Landlord's expense (unless the need for such compliance arises
                  out of any act, omission, negligence or intentional misconduct
                  of Tenant, in which event Tenant shall reimburse Landlord for
                  the cost of such compliance within 30 days after submission by
                  Landlord to Tenant of invoices evidencing the cost of such
                  compliance), shall promptly comply with all Legal
                  Requirements, Insurance Requirements and Permitted
                  Encumbrances relative to the Stephaneze Premises, whether or
                  not compliance therewith shall require Alterations or
                  interfere with the use or enjoyment of the Stephaneze
                  Premises. Landlord may contest any such Legal Requirement,
                  Insurance Requirement or Permitted Encumbrance (and not comply
                  therewith pending the resolution of such contest); provided,
                  that such contest has no adverse affect on Tenant's use or
                  occupancy of the Leased Premises. Tenant shall not at any time
                  use or occupy the Stephaneze Premises, or suffer or permit
                  anyone to use or occupy the Stephaneze Premises, in any
                  manner, or do anything in the Stephaneze Premises, or suffer
                  or permit anything to be done, brought into or kept on the
                  Stephaneze Premises which (A) constitutes a nuisance, public
                  or private, (B) makes unobtainable from reputable insurance
                  companies authorized to do business in New York State all risk
                  property insurance, or liability, elevator, boiler or other
                  insurance at standard rates, or (C) discharges objectionable
                  fumes, vapors or odors.

            (v)   Landlord shall keep in effect commercial general liability
                  insurance, including broad form bodily injury, personal
                  injury, property damage and blanket contractual insurance,
                  against claims arising out of or connected with the
                  possession, use, operation or condition of the Stephaneze
                  Premises ("Liability Insurance") with a combined single limit
                  of not less than $10,000,000 for all claims with respect to
                  bodily injury, property damage and personal injury with
                  respect to any one occurrence. All such Liability Insurance
                  shall name Tenant as an additional insured and provide that no
                  cancellation, reduction in amount or material change in
                  coverage thereof shall be effective until at least 30 days
                  after receipt by Tenant of written notice thereof. Landlord
                  may obtain the aforesaid insurance under blanket or umbrella
                  policies. On the date hereof (with respect to Liability
                  Insurance required to be carried by Landlord), and at least 7
                  days prior to each policy expiration, Landlord shall deliver
                  (or cause to be delivered) to Tenant certificates of all such
                  Liability Insurance.

            (vi)  Subject to the next sentence, Tenant shall have (A) the
                  exclusive right to use, disconnect or close (x) any pipe,
                  duct, conduit, utility line or similar installation running in
                  or through but not serving the Stephaneze Premises, or (y) any
                  exhaust duct running in or through or serving the Stephaneze
                  Premises, (B) the right to install in and through the
                  Stephaneze Premises new or additional pipes, ducts, conduits,
                  utility lines or similar installations, in locations adjacent
                  to ceiling slabs, demising walls or structural columns, in
                  each case in a manner so as not to unreasonably interfere with
                  the use or occupancy of the Stephaneze Premises as retail
                  space, (C) the right to maintain, repair and replace any of
                  the foregoing and (D) the right to enter the Stephaneze
                  Premises for (1) all or any of the foregoing purposes, (2) to
                  inspect the Stephaneze Premises or (3) to maintain or make
                  repairs, replacements, alterations, additions or improvements
                  in or to the Leased Premises; provided, that, except in case
                  of emergency or reasonably foreseeable or actual criminal
                  liability of Tenant, Tenant shall give Landlord reasonable
                  prior notice of any such entry and shall use reasonable
                  efforts to minimize interference with the use and occupancy of
                  the Stephaneze Premises arising by reason of such entry.
                  Notwithstanding the foregoing, except in case of emergency or
                  reasonably foreseeable or actual criminal liability of Tenant,
                  Tenant shall take no action pursuant to this Section
                  1.3(b)(vi) prior to the Stephaneze Restriction Date. The
                  Stephaneze Premises shall consist only of the space within the
                  inside surface of the structural (or centerline of any
                  non-structural) walls, windows, doors, columns, and floor
                  slabs bounding the Stephaneze Premises (exclusive of any such
                  space used for pipes, ducts, conduits, utility lines or
                  similar installations). If at any time any windows of the
                  Stephaneze Premises are either temporarily darkened or
                  obstructed by reason of maintenance, cleaning, repairs,
                  replacements, alterations, additions or improvements in or
                  about the Leased Premises or the

                  Stephaneze Premises, including by way of a sidewalk bridge (or
                  permanently darkened or obstructed if required by law), Tenant
                  shall have no liability to Landlord or any Occupant of the
                  Stephaneze Premises on account thereof; provided, that Tenant
                  shall use reasonable efforts not to darken or obstruct any
                  windows of the Stephaneze Premises and to minimize any such
                  darkening or obstruction when the same cannot reasonably be
                  avoided.

                  (c) Subject to the last sentence of this Section 1.3(c), if
Landlord shall fail to make any payment or perform any act required to be made
or performed by Landlord hereunder with respect or relating to the Stephaneze
Premises Tenant may (but shall be under no obligation to) without waiving or
releasing any obligation or default:

            (i)   in case of emergency, or reasonably foreseeable or actual
                  criminal liability of Tenant or interference with the use or
                  occupancy of, or the performance of the Base Building Upgrade
                  Work or the Fit-Out Work in, the Leased Premises, or

            (ii)  if Tenant shall give notice to Landlord referring to Tenant's
                  intent to exercise its self-help right under this Section
                  1.3(c), which notice shall specify Landlord's failure with
                  respect to the Stephaneze Premises and require such failure to
                  be remedied, and Landlord shall not remedy such failure within
                  30 days after the giving of such notice; provided, that in
                  case such failure cannot with due diligence be remedied by
                  Landlord within a period of 30 days, if Landlord proceeds as
                  promptly as may be reasonably possible after the giving of
                  such notice and with all due diligence to remedy such failure
                  and thereafter to prosecute the remedying of such failure with
                  all due diligence, the period of time after the receipt of
                  such notice by Landlord within which to remedy such failure
                  shall be extended for such period as may be necessary to
                  remedy the same with all due diligence,

make such payment or perform such act for the account and at the expense of
Landlord, and may enter upon the Stephaneze Premises or any part thereof for
such purpose and take all such action therein as, in the opinion of Tenant, may
be necessary or appropriate therefor. All payments so made by Tenant and all
costs and expenses (including without limitation attorneys fees and expenses)
incurred in connection with Tenant's exercise of its self-help right under this
Section 1.3(c), together with interest thereon at the Interest Rate, shall be
paid by Landlord to Tenant within 30 days after Landlord's receipt of Tenant's
demand therefor, accompanied by invoices evidencing the costs incurred by
Tenant. If Landlord objects to Tenant's exercise of its right of self-help under
this Section 1.3(c), then Tenant shall not be entitled to any reimbursement
under this Section 1.3(c) unless and until the matter is resolved in favor of
Tenant by Expedited Arbitration. Except in case of emergency or reasonably
foreseeable or actual criminal liability of Tenant, Tenant shall take no action
under this Section 1.3(c) prior to the Stephaneze Restriction Date.

                  (d) Landlord shall protect, indemnify and save harmless Tenant
from and against all liabilities, obligations, claims, damages, penalties,
causes of actions, costs and expenses (including, without limitation, attorneys'
fees and expenses) imposed upon or incurred by or asserted against Tenant by
reason of any action by Landlord to recover possession of the Stephaneze
Premises.

                  (e) Landlord shall reimburse Tenant for all incremental
out-of-pocket costs incurred by Tenant prior to the commencement of the Term
with respect to the Stephaneze Premises on account of the Stephaneze Premises,
or the use or occupancy thereof, including any such costs arising out of any
maintenance, repair or replacement of any utility lines serving the Stephaneze
Premises (unless the need therefor arises out of any act, omission, negligence
or intentional misconduct of Tenant). Such reimbursement shall be due from time
to time within 30 days after Tenant's presentation of an invoice detailing such
incremental out-of-pocket costs.

                  1.4 Tenant's Termination Options

                  (a) Subject to the further provisions of this Section 1.4,
Tenant shall have the option (each, a "Termination Option") to terminate this
Lease effective as of (i) September 30, 2004, (ii) September 30, 2006, (iii)
June 30, 2008 or (iv) June 30, 2013 (each of the dates set forth in the
preceding clauses (i) - (iv) is called a "Termination Date"), by giving an
exercise notice (the "Termination Notice") to Landlord on or before the date
that is (A) one year prior to the applicable Termination Date in the case of a
termination as of September 30, 2004 or September 30, 2006 or (B) 18 months
prior to the applicable Termination Date in the case of a termination as of June
30, 2008 or June 30, 2013. Time is of the essence with respect to the giving of
any Termination Notice. Tenant may, by notice to Landlord at any time, waive any
one or more of its Termination Options.

                  (b) If Tenant timely exercises a Termination Option providing
for the termination of this Lease as of September 30, 2004, September 30, 2006
or June 30, 2008, then Tenant shall pay to Landlord, on or before September 1,
2004, September 1, 2006 or June 1, 2008, as the case may be (the "Cancellation
Payment Payment Date"), in addition to the Basic Rent, Supplemental Rent and Tax
Payment due on the Cancellation Payment Payment Date, the applicable
Cancellation Payment. "Cancellation Payment" means

                  (i)   the amount of the Unamortized Fit-Out Work Investment as
                        of the applicable Cancellation Payment Payment Date,
                        plus

                  (ii)  in the case of a Termination Option providing for the
                        termination of this Lease as of September 30, 2004 or
                        September 30, 2006, the Basic Rent and the Tax Payments
                        that would be payable for the six month period
                        immediately following the applicable Termination Date if
                        Tenant had not exercised the Termination Option (the
                        portion of the Cancellation Payment referred to in this
                        clause (iii) is called the "Rent Based Cancellation
                        Payment").

<PAGE>   19

                  (c) If Tenant timely exercises any Termination Option, then on
the applicable Termination Date (i) this Lease shall terminate, (ii) Tenant
shall deliver to Landlord vacant possession of the Leased Premises subject to
and in accordance with all applicable provisions of this Lease as if the
Termination Date were the Expiration Date, and (iii) Basic Rent, Supplemental
Rent and Tax Payments due hereunder shall be payable through and apportioned as
of the Termination Date, and (except as provided in Section 32(b) with respect
to any holdover) Tenant shall have no liability for Basic Rent, Supplemental
Rent or Tax Payments which would otherwise have been payable after the
Termination Date.

                  (d) If (i) Tenant timely exercises a Termination Option as of
September 30, 2004 or September 30, 2006 and (ii) any Reimbursable Alteration
(other than Reimbursable Removal of Hazardous Substances) was performed prior to
the applicable Termination Date, then on or before the applicable Termination
Date, Landlord shall pay to Tenant, in respect of each such Reimbursable
Alteration, an amount equal to the excess of (A) the Reimbursement Amount which
would have been payable by Landlord with respect thereto if the Cost Division
Date with respect to such Reimbursable Alterations had been the applicable
Termination Date rather than the last day of the Second Rent Period, over (B)
the Reimbursement Amount paid by Landlord with respect thereto; provided, that
if with respect to any such Reimbursable Alteration Landlord shall have been
required to pay the Limited Reimbursement Amount rather than the Reimbursement
Amount and shall not have subsequently been required to make the payment
described in Section 6.4(g)(vi), then rather than the excess of the amount
described in clause (A) above over the amount described in clause (B) above
Landlord shall pay to Tenant, in respect of such Reimbursable Alteration, an
amount equal to the excess of (C) the Limited Reimbursement Amount which would
have been payable by Landlord with respect thereto if the Cost Division Date
with respect to such Reimbursable Alteration had been the applicable Termination
Date rather than the last day of the Second Rent Period, over (D) the Limited
Reimbursement Amount paid by Landlord with respect thereto.

                  1.5 Landlord's Financing.

                  (a) Landlord shall make reasonable efforts, as promptly as
reasonably possible, to cause the Financing Closing Date to occur. The term
"Financing Closing Date" shall refer to the date on which

                  (i)   Landlord has received full disbursement of one or more
                        new loans sufficient in amount to permit Landlord to
                        deposit, and Landlord has deposited (a) $17,350,000 into
                        the account described in Section 6 of the Initial
                        Improvements Agreement, and (b) $50,000,000 into the
                        account described in Section 7 of the Initial
                        Improvements Agreement,

                  (ii)  Landlord has caused the holders of all mortgages or
                        other liens on the Project (including but not limited to
                        the lender or lenders who shall have disbursed the new
                        loan or

                        Tenant a Non-Disturbance Agreement, and

                  (iii) Tenant shall have received the certificate called for by
                        the last paragraph of Section 5 of the Option Agreement

the date of the receipt of such Financing Termination Notice and neither party
shall have any further obligations or liabilities to the other, except that
Landlord shall reimburse Tenant in an amount not to exceed $6,700,000 for any
Qualified Prefinancing Costs incurred by Tenant. Tenant may make one or more
demands for reimbursement under this Section 1.5(b), each to be accompanied by
invoices paid or payable by Tenant, and each amount payable under this Section
1.5(b) shall be due within 30 days of such demand therefor. If any payment
required to be made pursuant to this Section 1.5(b) is not made when due, the

Tenant's right, title and interest in and to the plans and specifications, work,
equipment or other property to which such payment related (including the benefit
of any deposits or other payments made by Tenant and reimbursed by Landlord),
without recourse or representation.

                  "Qualified Prefinancing Costs" means any and all Costs paid or
incurred by Tenant for or in connection with the Base Building Work and/or the
Fit-Out Work on or prior to the date of termination of this Lease under this
Section 1.5(b), including any partial payments (e.g. deposits) with respect to

this Lease pursuant to this Section 1.5(b) or for which under commitments made
prior to the termination of this Lease pursuant to this Section 1.5(b) Tenant is
obligated, excluding in all cases any sums of which Tenant would be entitled to
a refund or which Tenant would be excused from paying if, promptly after
receiving notice of termination of this Lease under Section 1.5(b), Tenant gave
prompt notice of termination to Tenant's contractors, subcontractors or other
suppliers.

                  (c) If the Financing Closing Date shall not occur by September
30, 1997 Tenant shall have the right to arrange or provide on commercially
reasonable terms financing in the amount required

                        Landlord in connection with all such financing being

                        being provided under this Section 1(c) applicable to the
                        deposits referred to in clause (i) above and to a
                        pro-rata share of the points, fees and other expenses
                        referred to in clause (iii) above, and

                  (v)   to make all scheduled payments of principal and interest

Notwithstanding the provisions of Section 1.5(b) above, Landlord shall not have
the right to terminate this Lease prior to October 15, 1997 and if prior to that
date Tenant shall arrange or provide a commercially reasonable commitment for
such financing, Landlord shall accept the same and close the financing to be
provided thereunder and shall not have the right to terminate this Lease
pursuant to Section 1.5(b).

1, 1998).

            The term "Base Building Savings Constant Payment" shall mean the
constant monthly payment which would be required to fully amortize, with

Agreement) and ending June 1, 2008 with each such payment being applied first to
interest accrued at the Main Interest Rate and then to amortization (and with


                                      -12-
<PAGE>   23

interest commencing to accrue on the Base Building Savings as of one month
before the Base Building Savings Commencement Date).

plus 140 basis points per annum.

clause (i) of Section 1.5(a) is determined, and (ii) the interest rate on the

Boston to Landlord and Tenant at such time.

            The term "Unamortized Fit-Out Work Investment" shall mean, as of any
date, that amount which would be unamortized on such date if the Fit-Out Work

original principal amount equal to the Notional Main Loan Original Balance,
disbursed on the Financing Closing Date, providing for 216 constant monthly

monthly payment which would be required to fully amortize the Notional Main Loan
Original Balance over such 216 constant monthly payments, with each such payment
being applied first to accrued interest and then to a reduction in principal
(except that if the Financing Closing Date is other than the first day of a
month (x) the first payment shall be deemed to consist of interest only from the
date of such disbursement to the first day of the month after the month in which
such disbursement is made and to be due on such first day of such month and (y)
the aforesaid 216 constant monthly payments shall be deemed to begin on the
first day of the next month).

actually exercised by Tenant shall be disregarded. As used above, the term
"Comparable Treasury Rate" shall, as of any date, mean the yield to maturity of
U.S. Treasury securities maturing on or about June 1, 2008 as published by The

      2. Basic Rent, etc.

            2.1 Basic Rent

            (a) Tenant shall pay to Landlord, as fixed annual rent for the
Leased Premises, Basic Rent. Basic Rent shall be payable by Tenant to Landlord
in advance, in equal monthly installments, on the Rent Commencement Date and on
the first day of each and every month thereafter throughout the Term.

            (b) As used herein:

                        (i) "Basic Rent" means (A) during the period commencing
on June 1, 1998 (the "Rent Commencement Date"), to and including May 31, 2003
(the "First Rent Period"), a per annum rate equal to $8,420,095.88, payable in
equal monthly installments of $701,674.66, (B) during the period commencing on
June 1, 2003 to and including June 30, 2008 (the "Second Rent Period"), a per
annum rate equal to $10,573,515.14, payable in equal monthly installments of
$881,126.26, (C) during the period commencing on July 1, 2008 to and including

                                      -14-
<PAGE>   25

for such period and (D) during the period commencing on July 1, 2013 to and
including the Expiration Date (the "Fourth Rent Period") a per annum rate equal
to 95% of the Fair Market Rent for such period. Fair Market Rent shall be
determined in accordance with Section 2.2 below.

                        (ii) If (a) Tenant shall give a notice pursuant to
Section 6 of the Initial Improvements Agreement establishing the Base Building
Savings Commencement Date, and (b) there are any Base Building Savings, then
there shall be credited against the Basic Rent due for each of the months
beginning with the Base Building Savings Commencement Date and ending June 1,
2008, an amount equal to the Base Building Savings Constant Payment. The
aforesaid credit is herein called the "Base Building Savings Credit". In no
event shall Landlord ever be required to pay to Tenant any portion of the Base
Building Savings Credit.

            2.2 Determination of Fair Market Rent

            (a) Each determination of Fair Market Rent shall be made, to the
extent not inconsistent with this Section, in accordance with the rules from
time to time in effect of the American Arbitration Association or, if the
American Arbitration Association shall have ceased to function as an arbitration
association, of a successor or comparable organization (the "Rules"). There
shall be three arbitrators: one designated by Landlord; one designated by
Tenant; and one designated in the manner hereinafter described. Each arbitrator
shall, as of the date of his or her designation, be a real estate broker
licensed in the State of New York doing business in the Borough of Manhattan and
having at least 15 years experience in first-class Manhattan office building
leases. Not more than 30 months and not less than 24 months before the first day
of the Third Rent Period or the Fourth Rent Period, as applicable, Tenant shall
give to Landlord a notice designating the name and address of Tenant's
arbitrator ("Tenant's Designation Notice"). Landlord, by notice to Tenant given
not later than 20 days after the giving of Tenant's Designation Notice, shall
designate the name and address of Landlord's arbitrator.

      If either party shall fail timely to designate its arbitrator, and such
failure shall continue for 10 days after receipt by the failing party of notice
of such failure, such other party may designate an arbitrator on behalf of the
failing party. Promptly after the designation of the second of the two
arbitrators to be designated, such two arbitrators shall meet and attempt to
mediate between Landlord and Tenant an agreement upon the Fair Market Rent in
question. If, within 15 days after the designation of the second of the two
arbitrators to be designated, Landlord and Tenant have not agreed upon the Fair
Market Rent in question, such two arbitrators shall jointly designate a third
arbitrator. If, within 30 days after the designation of the second of the two
arbitrators to be designated, no third arbitrator shall have been so jointly
designated, such third arbitrator shall be designated pursuant to the Rules. The
arbitrators shall render their decision within 60 days after the designation of
the third arbitrator to be designated. Landlord and Tenant shall each pay the
fees and disbursements of the arbitrator designated by or on behalf of it, and
Landlord and Tenant shall share equally the fees and disbursements of the third
arbitrator, if any.

                        (b) "Fair Market Rent" means the fixed annual rent that
would be payable for the Leased Premises by a third-party tenant having the then
creditworthiness of Tenant under a five year lease commencing on the first day
of the Third Rent Period or the Fourth Rent Period (as the case may be) upon all
of the terms and conditions of this Lease to be applicable to the Third Rent
Period or Fourth Rent Period (as the case may be), including, without
limitation, the following:

                        (i)   that such fixed annual rent is payable from and
                              after the first day of the Third Rent Period or
                              the Fourth Rent Period (as the case may be),

                        (ii)  that the Initial Improvements Agreement is not
                              applicable to the Third Rent Period or the Fourth
                              Rent Period (as the case may be), and that Tenant
                              shall accept the Leased Premises in its "as-is"
                              condition at the commencement of the Third Rent
                              Period or the Fourth Rent Period (as the case may
                              be), and that in connection with the Third Rent
                              Period or the Fourth Rent Period (as the case may
                              be) Landlord shall not be required to perform any
                              work, pay any amount or render any services to
                              make the Leased Premises ready for Tenant's use
                              and occupancy or provide any abatement of Basic
                              Rent or other sums due hereunder,

                        (iii) that during the Third Rent Period or the Fourth
                              Rent Period (as the case may be), Tenant shall be
                              responsible for any increases in Taxes above the
                              Base Tax Amount, and

                        (iv)  that the ground floor of the Improvements are
                              legally permitted to be used for retail purposes,

and taking into account all relevant factors.

                        (c) Each arbitrator shall render as his or her
determination of the Fair Market Rent a fixed dollar amount per annum (in the
aggregate, not per rentable square foot), and shall give a notice to the other
arbitrators and Landlord and Tenant thereof. All notices pursuant to the
preceding sentence shall be given simultaneously at a meeting (called by the
third arbitrator on at least five Business Days' notice to Landlord and Tenant
and the other arbitrators) at which all three arbitrators and Landlord and
Tenant are present. The arithmetic average, of the two determinations closest to
one another shall be and constitute the determination of the arbitration;
provided, that if in any case the highest and lowest determinations are
equidistant from the middle determination, then the middle determination shall
be and constitute the determination of the arbitration.

            (a) Basic Rent, Supplemental Rent, Tax Payments and all other sums
payable by Tenant to Landlord hereunder, all of which shall constitute rent,

            (c) If Landlord fails timely to pay any sum payable by Landlord to

make under Section 11.2, which failure to make such payments is governed by
Article 38, or (ii) a payment which Landlord is required to make under Section 6
or Section 7 of the Initial Improvements Agreement, which failure to make such
payment is governed by Article 39, or (iii) a payment of net annual rental
payable under the Ground Lease which Landlord is required to make under Section
12.3, which failure to make such payment is governed by Article 38, Landlord
shall pay interest thereon from the date when such amount became due to the date
of Tenant's receipt thereof at the Interest Rate. Any sum payable by Landlord
for which no due date is specified in this Lease shall be due and payable on the
30th day after the giving of an invoice therefor.

            (d) If Tenant shall fail timely to pay the Cancellation Payment or
the Supplemental Rent payable under clause (b) of Section 2.3 when due then, in
addition to such Cancellation Payment or Supplemental Rent, Tenant shall pay as
additional rental upon demand (x) an amount equal to interest at the Interest
Rate on such Cancellation Payment (excluding the Rent-Based Cancellation
Payment) or on such Supplemental Rent from the Cancellation


                                      -17-

Payment Payment Date or June 1, 2008 (as the case may be) until payment in full
by Tenant of the Cancellation Payment or such Supplemental Rent and all amounts
required by this sentence, and (y) in case of any failure timely to pay the

interest at the Interest Rate on the Rent-Based Cancellation Payment from the
Cancellation Payment Payment Date until payment in full of the Cancellation
Payment and all other amounts required by this sentence. If Tenant shall fail
timely to pay the Cancellation Payment or the Supplemental Rent payable under
clause (b) of Section 2.3 when due then, in addition to the amounts which Tenant
is required to pay under the preceding sentence, Tenant shall indemnify Landlord
against all other losses, damages, costs and expenses arising out of such
failure.

      4. Net Lease; No Abatement

            Except as otherwise provided in the Initial Improvements Agreement,
Landlord shall not be required to provide any services or utilities to the

for retail uses so long as there remains throughout the Term a first-class
office building lobby on the ground floor of the Improvements. Tenant shall not
suffer or permit the Leased Premises or any part hereof, to be used by the
public in such a manner as would subject the Leased Premises or any part thereof
to a claim of adverse possession by the public.

            6.1 Generally

            (a) Subject to the provisions of this Lease, Tenant:

                        office building maintenance and operating standards
                        generally applicable in 1998 (collectively, the
                        "First-Class Standard"), keep the Leased Premises in
                        overall first-class order, condition and repair;

                                    (ii) shall promptly make all replacements in
                        and to the Leased Premises (whether interior or
                        exterior, structural or nonstructural, ordinary or
                        extraordinary, foreseen or unforeseen) which are
                        necessary or appropriate in a first-class office
                        building according to the standards thereof generally
                        applicable in 1998 (collectively, "Required
                        Replacements"); and

                                    (iii) may make additions, alterations and
                        replacements (other than Required Replacements) in and
                        to and, subject to the provisions of Section 1.1,
                        removals from the Leased Premises (collectively,
                        "Voluntary Alterations"; Required Replacements,
                        Structural Work and Voluntary Alterations are
                        collectively called "Alterations").

Notwithstanding the foregoing, (x) Tenant's obligation with respect to the shell
of the Building (excluding the roof) shall be limited to maintaining the same in
such condition as the same is required by applicable Legal Requirements to be
maintained and also in a condition not materially worse than the condition in
which the same was in on the date of this Lease, and (y) if Landlord shall give
a Cost Participation Limitation Notice with respect to any Reimbursable
Replacement or Reimbursable Legal Requirement Alteration, Tenant shall not be
obligated to Landlord to make such Reimbursement Replacement or Reimbursable
Legal Requirement


                                      -19-

Alterations nor, with respect to any such Reimbursable Replacement, to repair
the item which was to have been replaced.

                  (b) No Alteration may be undertaken if such Alteration would
(i) result in the Improvements not being a first-class office building or (ii)
materially and adversely affect any structural element of the Improvements or
any item of Major Building Equipment. Each Alteration shall be effected with due
diligence, in a good and workmanlike manner, and in compliance with all Legal
Requirements, Insurance Requirements and Permitted Encumbrances. All Structural
Work and all replacements of items of Major Building Equipment shall be of a
quality at least equal to the original installation. Landlord shall not be
liable to any contractors, subcontractors, laborers, materialmen, suppliers or
vendors for services performed or material provided on or in connection with the
Leased Premises. Landlord shall not be required to maintain, alter, repair,
rebuild or replace the Leased Premises or any part thereof. Tenant waives all
rights to make Alterations at Landlord's expense, except that Landlord shall in
accordance with the further provisions of this Article 6 make reimbursements to
Tenant on account of Reimbursable Alterations. Except as provided in Section
1.1, all Improvements arising from the making of any Alterations shall
immediately become the property of Landlord, shall be a part of the Leased
Premises and shall be subject to this Lease, and Tenant shall, upon demand of
Landlord, execute and deliver an appropriate instrument confirming Landlord's
title thereto.

                              caulking treatment done in conjunction with
                              repairs or replacement of the portion of the
                              curtain wall being caulked (other than any repairs
                              or replacement undertaken in order to avoid the
                              exclusion provided for in this clause (i)).

                        (ii)  replacement and/or repair of the Building's steel
                              frame, footings, foundations, columns, beams,

                              entirety (but not in part) required in order to
                              preserve the structural integrity of the Building
                              or the watertightness and airtightness of the

                        (iv)  replacement of the watertight membrane or other
                              watertight barrier under the Building's plaza, and
                              any removal, reinstallation, repair or replacement
                              of the Building's plaza arising out of such
                              replacement

                  (e) "Reimbursable Structural Work" means any Structural Work

negligence of Tenant or the Building management company employed by Tenant
occurring after such termination. Notwithstanding the foregoing, the first
$100,000 of Structural Work performed by Tenant in any calendar year which, but
for this sentence, would constitute Reimbursable Structural Work shall be deemed

<PAGE>   32

estimated by Tenant) shall be less than $500,000 then, unless Tenant, by notice
to Landlord, shall elect to treat the same as a Reimbursable Removal of
Hazardous Substances, such removal shall be deemed not to be a Reimbursable
Removal of Hazardous Substance. In applying the provisions of this clause (ii)
each removal contracted for separately (unless done so solely in order to avoid
the provisions of this Section 6) shall be considered a separate removal.

                  (g) "Reimbursable Alterations" means, collectively,

                              price of the Retained Bidder not actually paid by
                              Tenant, or

                        2)    the original contract price of Landlord's
                              Preferred Bidder or, if Tenant shall have timely
                              given the Dispute Notice and the Appropriate
                              Engineer shall have selected Tenant's Selected
                              Bidder, the original contract price of Tenant's

                  (k) "Determined Amount" means the lower of

                        1)    the original contract price of the Retained

                              given the Dispute Notice and the Appropriate
                              Engineer shall have selected Tenant's Selected
                              Bidder, the original contract price of Tenant's
                              Selected Bidder.

                  (l) "Cost Division Date" means, (i) with respect to any

Alterations commenced during the Third Rent Period, the last day of the Third
Rent Period, or (iii) with respect to any Reimbursable Alterations commenced
during the Fourth Rent Period, the last day of the Fourth Rent Period.

                  (m) "Measuring Fraction" means, with respect to any
Reimbursable Alteration (other than any Reimbursable Removal of Hazardous
Substances), the fraction whose


                                      -22-
<PAGE>   33

numerator is the number of months in the period from the Cost Division Date with
respect to such Reimbursable Alteration to the end of the expected useful life
of such Reimbursable Alteration and whose denominator is the number of months in
the period from the Estimated Substantial Completion Date of such Reimbursable
Alteration to the end of the expected useful life thereof. Any dispute as to the
reasonableness of any Estimated Substantial Completion Date, and any dispute as
to the expected useful life of any Reimbursable Alteration, shall be determined
by the Appropriate Engineer. As to any Reimbursable Removal of Hazardous
Substances, the Measuring Fraction shall be one (1.00).

If Landlord and Tenant shall disagree (i) as to whether any item is an item of
Major Building Equipment, or (ii) as to whether any replacement is a
Reimbursable Replacement, or (iii) as to whether any work is Structural Work, or
(iv) as to whether any Structural Work is Reimbursable Structural Work, or (v)
as to whether a Legal Requirement requires an Alteration, or (vi) as to whether
an Alteration is a Legal Requirement Alteration, or (vii) as to whether any
Legal Requirement Alteration is a Reimbursable Legal Requirement Alteration, or
(viii) as to whether any Alteration is a Qualified Alteration, or (ix) as to
whether any removal of any Hazardous Substance is a Reimbursable Removal of
Hazardous Substances, the matter shall in each case be determined by the
Appropriate Engineer. Notwithstanding the foregoing, any dispute under clause
(vii) - in so far as it relates to whether in accordance with GAAP an item
should be capitalized - shall be determined by the Accountant.

            6.3 Submission and Approval of Plans and Specifications in Certain
Instances.

                  (a) Required Submissions. Prior to:

                                    (i) performing any of the Base Building
                        Upgrade Work; or

                                    (ii) undertaking any Reimbursable
                        Replacement, any Structural Work (whether or not
                        Reimbursable Structural Work), any Legal Requirement
                        Alteration (whether or not a Reimbursable Legal
                        Requirement Alteration) or any Qualified Alteration;

Tenant shall (subject to Section 6.3(f)) submit all of the Plans and
Specifications therefor to Landlord for Landlord's approval, together with, in
case Tenant contends that the work in question is a Reimbursable Alteration, (i)
a statement to that effect, and (ii) a good faith estimate of the Costs of such
Reimbursable Alteration prepared by a reputable architect, engineer or
contractor. Each such submission is herein called a "Plans Submission Notice".

Landlord shall give notice (the "Plans and Specifications Notice") to Tenant of
Landlord's approval or disapproval of any Plans and Specifications within 20
Business Days after the date upon which the same are given to Landlord (which
Plans and Specifications Notice shall, in the case of a disapproval, be
accompanied by a reasonably complete and specific statement of the reasons for
disapproval); provided, that


                                      -23-
<PAGE>   34

                                    (A) with respect to all Plans and
                        Specifications submitted by Tenant prior to Tenant's
                        occupancy of the Leased Premises for the conduct of
                        business, the aforesaid 20 Business Day period shall be
                        shortened to 10 Business Days, and

                                    (B) with respect to all Plans and
                        Specifications submitted by Tenant after Tenant's
                        occupancy of the Leased Premises for the conduct of
                        business, if (i) at least 10 Business Days before the
                        date upon which Tenant submits all of the Plans and
                        Specifications for the work in question to Landlord,
                        Tenant gives notice to Landlord that Tenant intends to
                        make any replacement of an item of Major Building
                        Equipment or to undertake any Structural Work, Legal
                        Requirement Alteration or Qualified Alteration (which
                        notice shall specify the general nature of the work and
                        an estimated date for the submission of all of the Plans
                        and Specifications therefor to Landlord) and (ii) Tenant
                        delivers all of the Plans and Specifications for the
                        work in question to Landlord within 2 Business Days of
                        the estimated submission date set forth in Tenant's
                        notice, then the aforesaid 20 Business Day period shall
                        be shortened to 10 Business Days.

If Tenant's notice shall have included a statement that the work in question is
a Reimbursable Alteration, the Plans and Specifications Notice shall include
Landlord's agreement or disagreement with such statement.

                  (b) Disapproval Only Under Certain Circumstances. Landlord
shall not disapprove any Plans and Specifications unless the work contemplated
thereby would (i) result in the Improvements not being a first-class office
building or (ii) materially and adversely affect any structural element of the
Improvements or any item of Major Building Equipment. If Tenant disputes
Landlord's right to disapprove, the matter shall be determined by the
Appropriate Engineer.

                  (c) Certain Conditions. Subject to Sections 6.3(d) and (f),
Tenant shall not perform any Base Building Upgrade Work or undertake any
Reimbursable Replacement, Structural Work, Legal Requirement Alteration or
Qualified Alteration unless and until (i) Landlord shall approve (or be deemed
to have approved) the Plans and Specifications therefor in a Plans and
Specifications Notice or (ii) the Appropriate Engineer shall determine that
Landlord did not have the right to disapprove such Plans and Specifications
pursuant to this Lease.

                  (d) Failure to Give timely Notice. Subject to the provisions
of the next paragraph, if Landlord shall fail timely to give Tenant a Plans and
Specifications Notice, Tenant may proceed with the work in question, and if
Landlord thereafter disapproves the Plans and Specifications therefor Tenant may
continue such work unless the Appropriate Engineer determines that Landlord had
the right to disapprove pursuant to this Lease. If the Appropriate


                                      -24-

Engineer so determines, Tenant shall cease such work, but the work done by
Tenant to the date of the Appropriate Engineer's determination shall not
constitute a default hereunder if Tenant thereupon commences and thereafter
diligently prosecutes to completion such remedial work (including, without
limitation, the removal of the work theretofore done by Tenant and the
restoration of the affected area of the Leased Premises) as Landlord may
reasonably determine to be appropriate in the circumstances (unless Tenant shall
dispute Landlord's determination, in which case the remedial work, if any, to be
done by Tenant shall be determined by the Appropriate Engineer).

                  Notwithstanding the provisions of the foregoing paragraph, if
(i) Tenant's Plans Submission Notice shall include the following statement in
block capital letters: "THIS NOTICE IS BEING GIVEN UNDER SECTION 6.3(a) OF OUR
LEASE. YOUR FAILURE TIMELY TO RESPOND WILL RESULT IN YOUR BEING DEEMED TO HAVE
APPROVED THE PLANS AND SPECIFICATIONS INCLUDED HEREWITH", and (ii) Landlord
shall fail timely to give to Tenant a Plans and Specifications Notice with
respect to such Plans and Specifications, then Landlord shall be deemed to have
given to Tenant a Plans and Specifications Notice approving such Plans and
Specifications and any Plans and Specifications Notice thereafter given by
Landlord disapproving such Plans and Specifications shall be void and of no
effect.

                  If (i) Tenant's Plans Submission Notice shall include the
following statement in block capital letters: "THIS NOTICE IS BEING GIVEN UNDER
SECTION 6.3(a) OF OUR LEASE WITH RESPECT TO A REIMBURSABLE ALTERATION. YOUR
FAILURE TIMELY TO DISAGREE WITH TENANT'S STATEMENT THAT THE WORK CALLED FOR BY
THE PLANS AND SPECIFICATIONS INCLUDED HEREWITH CONSTITUTES A REIMBURSABLE
ALTERATION WILL RESULT IN YOUR BEING DEEMED TO AGREE THAT SUCH WORK CONSTITUTES
A REIMBURSABLE ALTERATION." and (ii) Landlord shall fail timely to give to
Tenant a Plans and Specifications Notice with respect to such Plans and
Specifications indicating that Landlord disagrees with Tenant's statement that
the work called for by such Plans and Specifications constitutes a Reimbursable
Alteration, then Landlord shall be deemed to have agreed that such work
constitutes a Reimbursable Alteration.

                  (e) Submission of Certain Plans and Specifications Not
Requiring Approval. At the request of Landlord (made not more frequently than
once in any 12-month period), Tenant shall submit to Landlord Plans and
Specifications for all Alterations (other than Plans and Specifications required
to be submitted to Landlord pursuant to Section 6.3(a)) to the extent that such
Plans and Specifications have been prepared and have not theretofore been
submitted to Landlord. Landlord shall have no right to approve any Plans and
Specifications submitted by Tenant pursuant to this Section 6.3(e) unless it is
determined that such Plan and Specifications should have been submitted for
approval under Section 6.3(a).

                  (f) Emergencies. Provided that Tenant shall have given
Landlord prompt telephonic notice (confirmed in writing as soon as reasonably
practicable) of an emergency, Tenant may (without first complying with the
applicable provisions of Sections


                                      -25-
<PAGE>   36

6.3(a)(b), (c) and (e)) proceed with such aspects of any Alteration as Tenant 
may reasonably deem necessary in light of the emergency, but as promptly as
reasonably practicable thereafter Tenant shall comply with the applicable
provisions of said sections. Any dispute as to Tenant's right to avail itself of
this Section 6.3(f) shall be determined by the Appropriate Engineer.

            6.4 Reimbursable Alterations

            (a) Submission of Bids; Different Score of Work Statement.

            (1) In the case of any Reimbursable Alteration, Tenant shall
(subject to Section 6.4(f)), simultaneously with the submission of all of the
Plans and Specifications therefor to Landlord (or as soon thereafter as
reasonably practicable, but in no event later than the date which is 5 Business
Days prior to the date upon which Landlord is required to give the Plans and
Specifications Notice), deliver to Landlord a list of at least 3 reputable
contractors (collectively, the "Original Bidders") from whom Tenant proposes to
obtain bids for the work. Landlord shall have the right, exercisable by notice
to Tenant delivered not later than 10 Business Days after receipt by Landlord of
the list of the Original Bidders, to designate no more than three additional
reputable contractors (which may include Landlord or an affiliate of Landlord)
from whom Landlord desires Tenant to obtain bids (collectively, the "Additional
Bidders"). Tenant shall, as promptly as reasonably practicable, obtain bids from
at least two of the Original Bidders and solicit bids from all of the Additional
Bidders (if any) on a competitive basis and submit all bids obtained (together
with the proposed contracts relating thereto) to Landlord together with (x)
Tenant's reasonable estimate of the date of substantial completion of the work
in question (the "Estimated Substantial Completion Date") and (y) Tenant's
reasonable estimate of reasonable fees and disbursements of any architect or
engineer retained by Tenant in connection with the work in question, and within
5 Business Days after receipt thereof Landlord shall give notice to Tenant
designating the Original Bidder or the Additional Bidder (in either case being a
bidder from whom Tenant has obtained a bid) which in Landlord's judgment should
perform the work in question (the bidder so designated by Landlord being called
"Landlord's Preferred Bidder"). All such bids shall be on a lump sum or
guaranteed maximum amount basis. Tenant shall have the right, exercisable by
notice (the "Dispute Notice") given to Landlord within 5 Business Days after the
date upon which Tenant receives notice of the identity of Landlord's Preferred
Bidder (which Dispute Notice shall specify the Original Bidder or the Additional
Bidder ("Tenant's Selected Bidder") which Tenant proposes to select to do the
work in question), to dispute Landlord's designation of Landlord's Preferred
Bidder, and if the Dispute Notice shall be timely given, the Appropriate
Engineer shall select either Landlord's Preferred Bidder or Tenant's Selected
Bidder as the bidder which (in light of the bid, contract terms, reputation and
experience of such bidder) is most appropriate to do the work in question.
Notwithstanding Landlord's designation of, or the Appropriate Engineer's
selection of, Landlord's Preferred Bidder, Tenant may retain any Original Bidder
or Additional Bidder from whom Tenant has obtained a bid in accordance with this
Section 6.4(a) to do the work in question (the bidder so retained being called
the "Retained Bidder").

            (2) If Landlord believes that the Reimbursable Alteration reflected
in the Plans and Specifications submitted by Tenant is not the most appropriate
Alteration to address


                                      -26-
<PAGE>   37

the condition in question (in the case of a Reimbursable Replacement or
Reimbursable Structural Work) or to comply with the Legal Requirement in
question (in the case of a Reimbursable Legal Requirement Alteration) or to
effect removal (in the case of Reimbursable Removal of Hazardous Substances)
then, Landlord shall include in its notice designating Landlord's Preferred
Bidder a statement to that effect (such statement being herein called a
"Different Scope of Work Statement") and shall include with such notice (x) such
revisions to or such replacement for the Plans and Specifications submitted by
Tenant as Landlord believes are needed to reflect such most appropriate
Alteration ("Landlord's Revised Plans"), (y) a list of at least 3 reputable
contractors from whom Landlord desires Tenant to obtain bids for the performance
of the Reimbursable Alteration in accordance with Landlord's Revised Plans
("Landlord's Alternate Bidders") and who may be the same as or different from
the Additional Bidders, and (z) if Landlord believes that the Alteration
reflected in Landlord's Revised Plans is not a Reimbursable Alteration, a
statement to that effect. In such a case, Tenant may elect to perform the
Alteration in question either pursuant to Landlord's Revised Plans or, subject
to Section 6.3(c), pursuant to the Plans and Specifications submitted by Tenant,
subject, in either case, to the provisions of Section 6.4(h). If Landlord shall
include the statement described in clause (z) above, and Tenant shall disagree
therewith, the dispute shall be resolved by the Appropriate Engineer.

            If (A) Tenant's notice accompanying Tenant's submission to Landlord
of the bids required to be submitted to Landlord under Section 6.4(a)(1) shall
include the following statement in block capital letters: "THIS NOTICE IS BEING
GIVEN TO YOU UNDER SECTION 6.4(a) OF OUR LEASE WITH RESPECT TO A REIMBURSABLE
ALTERATION. YOUR FAILURE TIMELY TO FURNISH A DIFFERENT SCOPE OF WORK STATEMENT
WILL RESULT IN YOUR LOSING THE RIGHT TO FURNISH A DIFFERENT SCOPE OF WORK
STATEMENT. IF YOU FURNISH A DIFFERENT SCOPE OF WORK STATEMENT YOUR FAILURE TO
INCLUDE THEREIN A STATEMENT THAT YOU DO NOT BELIEVE THAT THE ALTERATION CALLED
FOR THEREBY IS NOT A REIMBURSABLE ALTERATION WILL RESULT IN YOUR BEING DEEMED TO
AGREE THAT SUCH ALTERATION CONSTITUTES A REIMBURSABLE ALTERATION" and (B)
Landlord shall fail to include in its notice designating Landlord's Preferred
Bidder a Different Scope of Work Statement or shall fail to include with such
notice Landlord's Revised Plans or shall fail to include with such notice a list
of Landlord's Alternate Bidders, then Landlord shall be deemed to have waived
its rights under this Section 6.4(a)(2) with respect to the Reimbursable
Alteration in question. If (i) Tenant's notice accompanying Tenant's submission
to Landlord of the bids required to be submitted to Landlord under Section
6.4(a)(1) shall include the statement set forth in clause (i) of the preceding
sentence, and (ii) Landlord shall furnish a Different Scope of Work Statement
and shall fail to include therein a statement that Landlord does not believe
that the Alteration called for thereby is not a Reimbursable Alteration, then
Landlord shall be deemed to have agreed that such Alteration is a Reimbursable
Alteration.

            (b) Reimbursement Amount. Landlord shall, in accordance with Section
6.4(d) or 6.4(e), reimburse Tenant on account of any Reimbursable Alteration in
an amount (the "Reimbursement Amount") equal to the product of the Measuring
Fraction multiplied by the sum of (i) the Base Amount for the work in question,
plus (ii) any Qualified Overruns; plus (iii) the reasonable fees and
disbursements of any architect or engineer retained


                                      -27-
<PAGE>   38

by Tenant in connection with the work in question (the sum of the amounts
referred to in clauses (i), (ii) and (iii) being herein called the "Gross
Amount"). Any dispute as to the reasonableness of the incurrence by Tenant of
any Cost under clause (ii) or (iii) above in connection with the work in
question, or as to the reasonableness of the amount of any such Cost, shall be
determined by the Appropriate Engineer.

            (c) Overruns; Qualified Overruns. At any time during the performance
of any Reimbursable Alteration, Tenant may give notice (an "Overrun Notice") to
Landlord specifying any cost (an "Overrun") in excess of the original contract
price of Tenant's Selected Bidder which Tenant expects to incur and which Tenant
contends was unforeseeable by Tenant at the time of commencement of the work
(each Overrun Notice to specify the nature of and reasons for the Overrun in
question in reasonably complete and specific detail). Within 10 Business Days
after receipt of an Overrun Notice, Landlord shall notify Tenant as to whether
or not in Landlord's judgment the Overrun in question is reasonable in amount in
the circumstances and was unforeseeable by Tenant at the time of commencement of
the work. If Tenant shall dispute Landlord's judgment, the reasonableness of the
amount of, and the foreseeability by Tenant of, the Overrun in question shall be
determined by the Appropriate Engineer. Any Overrun determined by Landlord or
the Appropriate Engineer to be reasonable in amount in the circumstances and
unforeseeable by Tenant at the time of commencement of the work shall be a
"Qualified Overrun". Tenant shall not be chargeable with the failure by any
Contractor to foresee any Overrun.

            (d) Reimbursement Upon Full Completion. Except in the case of a
Reimbursable Alteration in respect of which an Extended Completion Notice has
been given, Landlord shall upon the full completion of the work in question and
within 30 days after Landlord's receipt of Tenant's request therefor remit the
Reimbursement Amount to Tenant; provided, that Landlord shall not be obligated
to make such remittance unless:

                        (i)   Tenant's request for remittance shall be
                              accompanied by (A) a certificate of Tenant (in
                              form reasonably satisfactory to Landlord) stating
                              that an amount at least equal to the Reimbursement
                              Amount has been paid to contractors,
                              subcontractors, materialmen, engineers, architects
                              or other persons (whose names and addresses and a
                              description of the work involved shall be stated)
                              who have furnished labor, materials, supplies,
                              permits or services for the work in question
                              (collectively, "Contractors") and that to Tenant's
                              best knowledge (after due inquiry) there is no
                              outstanding indebtedness due for labor, materials,
                              supplies, permits or services in any manner
                              connected with the work in question which if
                              unpaid might be the basis for any type of lien on
                              the Leased Premises or any part thereof, and (B) a
                              certificate of the architect or engineer who
                              prepared the related Plans and Specifications (in
                              form reasonably


                                      -28-
<PAGE>   39

                               satisfactory to Landlord) stating that such work
                               has been fully completed in a good and
                               workmanlike manner and in accordance with the
                               Plans and Specifications (as approved by Landlord
                               or as determined by the Appropriate Engineer to
                               have been required to be approved by Landlord
                               pursuant to this Lease);

                        (ii)  Landlord shall have received (A) true copies of
                              all bills paid by Tenant to Contractors in
                              connection with the work in question, (B) an
                              instrument in writing from any title company
                              insuring Landlord's estate in the Project
                              certifying that there are no undischarged
                              mechanics', laborers' or materialmen's liens
                              affecting any part of the Project (other than
                              liens, if any, in respect of which Landlord has
                              consented to take security pursuant to Article 
                              13(a)(ii)) and

                        (iii) no Event of Default shall have occurred and be
                              continuing.

            (e) Reimbursement as Work Proceeds. If at any time prior to or
during the performance of any Reimbursable Alteration Tenant determines that the
full completion thereof will not occur within six months after the commencement
of such Reimbursable Alteration, Tenant shall give Landlord notice of such
determination (an "Extended Completion Notice") and thereafter Landlord shall
from time to time within 30 days after Landlord's receipt of Tenant's request
therefor (but in no event more frequently than once during any 30-day period)
make advances to Tenant on account of the Reimbursement Amount for the work in
question (collectively, "Reimbursement Advances"); provided, that:

                        (i)   no Reimbursement Advance shall be made until
                              Tenant shall have delivered to Landlord evidence
                              reasonably acceptable to Landlord that Tenant has
                              paid Contractors engaged in the work in question
                              an aggregate amount (the "Benchmark Amount") equal
                              to the positive remainder, if any, obtained by
                              subtracting the Determined Amount for the work in
                              question from the original contract price of the
                              Retained Bidder, and Reimbursement Advances shall
                              be made only for amounts paid by Tenant to such
                              Contractors which are in excess of the Benchmark
                              Amount;

                        (ii)  no Reimbursement Advance (other than the final
                              Reimbursement Advance) shall be due unless:


                                      -29-
<PAGE>   40

                        (a)   Tenant's request for such Reimbursement Advance
                              shall be accompanied by (x) a certificate of
                              Tenant (in form reasonably satisfactory to
                              Landlord) stating that (1) the amount of the
                              Reimbursement Advance then requested has been paid
                              by Tenant to Contractors (whose names and
                              addresses and a description of the work involved
                              shall be stated) engaged in the work in question,
                              (2) the amount of the Reimbursement Advance then
                              requested (when taken together with the aggregate
                              amount of all Reimbursement Advances theretofore
                              made by Landlord) exceeds neither 90% of the
                              Reimbursement Amount nor the product of the
                              Determined Amount multiplied by the percentage
                              (the "Completed Percentage") of the work called
                              for in the contract of the Retained Bidder which
                              has actually been installed in the Leased
                              Premises, (3) the amount of the Reimbursement
                              Advance, when added to all amounts paid by Tenant
                              to Contractors engaged in the work in question and
                              not reimbursed by Landlord by way of prior
                              Reimbursement Advances or the then Reimbursement
                              Advance (but excluding the Benchmark Amount) is at
                              least equal to the quotient obtained by dividing
                              the amount of the then requested Reimbursement
                              Advance by the Measuring Fraction and (4) no part
                              of the cost of the work described in any previous
                              or then pending request for a Reimbursement
                              Advance has been or is being made the basis for
                              the Reimbursement Advance then being requested,
                              and (y) a certificate of the architect or engineer
                              who prepared the related Plans and Specifications
                              (in form reasonably satisfactory to Landlord)
                              stating in substance that the Completed Percentage
                              has been reached and that the work has been
                              performed in a good and workmanlike manner and in
                              accordance with the Plans and Specifications (as
                              approved by Landlord or as determined by the
                              Appropriate Engineer to have been required to be
                              approved by Landlord p
