                  the Initial Improvements Agreement of even date herewith
                  between Landlord and Tenant.

            Article 2. Demise of Premises; Term.

            2.1 Landlord hereby leases and demises to Tenant, and Tenant hereby
hires and takes from Landlord, upon and subject to the covenants, agreements,
terms, provisions and conditions of this Lease, the Premises. For the purposes
of this Lease: the term "Full Premises Floor" shall mean any floor of the
Building on or above the mezzanine level all of the leasable area of which is
leased to Tenant, and the term "Partial Premises Floor" shall mean any floor of
the Building on or above the mezzanine level some but not all of the leasable
area of which is leased to Tenant.

            2.2 This Lease is effective on the Effective Date. The term shall
commence on the Term Commencement Date and shall end at 11:59 p.m. on the
Expiration Date, or on such earlier date upon which the term may expire or be
terminated pursuant to any of the conditions of limitation or other provisions
of this Lease or pursuant to law.

            2.3 Landlord agrees to deliver the Premises, or portions thereof, in
accordance with the dates set forth in Exhibit C under the column heading
"Scheduled Delivery Date" (each floor, or a portion of a floor as described in
Exhibit C shall be deemed an "Applicable Portion"), and may deliver any
Applicable Portion to Tenant on any date earlier than the Scheduled Delivery
Date of such Applicable Portion, upon sixty (60) days' notice to Tenant of such
earlier delivery date. Prior to delivering the 16th floor, the 37th floor or the
40th floor Landlord shall complete Landlord's Work (as hereinafter defined) with
respect thereto. As used in this Lease the term "Delivery Date" with respect to
any


                                        4
   16

Applicable Portion shall mean the date of the actual delivery thereof; provided,
however, that in the case of the 16th floor, the 37th floor or the 40th floor
the term "Delivery Date" shall mean the later of (i) the date of the actual
delivery thereof, and (ii) the date of completion of Landlord's Work with
respect thereto. As used herein, the phrase "deliver" or "delivery" shall refer
to delivery to Tenant of vacant possession. Landlord represents to Tenant that
(except as provided in the next paragraph), pursuant to the terms thereof or the
terms of other written agreements now in effect, each lease now covering any
Applicable Portion will expire or terminate on or prior to Scheduled Delivery
Date relative to such Applicable Portion, it being understood that (i) no
holding over by any tenant beyond such expiration or termination shall give rise
to or constitute a breach of the representation set forth in this sentence, and
(ii) the provisions of Section 2.5 below shall not be applicable to any breach
of such representation.

            Landlord has not yet obtained surrender agreements from the tenant
of the 22nd floor or from space E on the 21st floor. If the Delivery Date of the
22nd floor does not occur on or before January 1, 1999 Tenant shall have the
right, by giving notice to Landlord prior to such Delivery Date, to revoke its
leasing of the 22nd floor pursuant to this Article 2. If the Delivery Date of
such space E does not occur on or before January 1, 1999 Tenant shall have the
right, by giving notice to Landlord prior to such Delivery Date, to revoke its
leasing of space E pursuant to this Article 2.

            Tenant acknowledges that Nomura Capital Management, Inc. ("Nomura")
has an option to lease space C on the 26th floor exercisable on or before
February 1, 2007 for delivery to Nomura no later than August 1, 2007. If Nomura
exercises such option, Landlord shall promptly notify Tenant and the term of
this Lease shall expire with respect such space C on July 31, 2007.

            2.4 Within thirty (30) days after the Delivery Date with respect to
any Applicable Portion, at the request of the other party, Landlord and Tenant
shall execute a mutually acceptable instrument specifying the exact calendar
dates of the Term Commencement Date, the Delivery Date of such Applicable
Portion, the Rent Commencement Date with respect to such Applicable Portion,
Tenant's Proportionate Share following the Delivery Date and, following the Last
Delivery Date, the Initial Expiration Date.

            2.5 Pursuant to Section 223-a of the Real Property Law of the State
of New York and notwithstanding any other law of like import now or hereafter in
force, the parties hereto expressly provide that, if any Applicable Portion of
the Premises are not available for delivery to Tenant on the Scheduled Delivery
Date, Tenant shall not have any claim against Landlord, except as described in
Section 3.5, nor any right to rescind this Lease. Landlord shall use
commercially reasonable efforts, including commencing eviction proceedings and
diligently prosecuting the same to completion, at Landlord's cost and expense,
to obtain possession of any Applicable Portion that is not available for
delivery to Tenant on the Scheduled Delivery Date by reason of the holding over
in the space by a prior tenant thereof.

                  (16) legal and accounting fees and disbursements;

                  (17) liabilities, damages, awards and judgments including
            interest thereon, paid or incurred by Landlord and arising from the
            ownership, operation, maintenance and repair of the Building and the

            (a) all liabilities, damages, awards and judgments for injury or
            death to persons and for property damage arising from ownership,

            whether or not herein mentioned that would, under generally accepted

            If during any period for which the Operating Costs are being
      computed, including the Base Operating Year, Landlord is not for all or
      any part of such period furnishing any particular work or service (the
      cost of which if performed by Landlord would constitute an Operating Cost)
      to more than five percent (5%) of the rentable portion of the office area
      in the Building due to the fact that more than five percent (5%) of the
      rentable portion of the office area of the Building is not leased to a
      tenant or that Landlord is not obligated to perform the work or service in
      that portion, then the amount of the Operating Costs for that period shall
      be deemed, for the purposes of this Article, to be increased by an amount
      equal to the additional Operating Costs that reasonably would have been
      incurred during that period by Landlord if it had at its own expense
      furnished the work or service to ninety-five percent (95%) of the rentable
      portion of the office area in the Building.

      "Operating Costs" shall not include any of the following:

            Building on or below the mezzanine level of the Building, (ii) the

            therefor out of insurance proceeds or otherwise, or for which
            Landlord would be reimbursed under a standard "all risk" policy that
            an owner of a building similar to the Building would typically carry
            containing a deductible limit not exceeding the deductible limit
            that an owner of a building similar to the Building would typically
            carry;

                  (6) leasing commissions or advertising expenses incurred in
            leasing or procuring tenants for the Building and legal expenses
            incurred in preparing leases for tenants or in enforcing the terms
            of any lease;

                  (7) legal fees, expenses and disbursements (other than those
            reasonably incurred in connection with the maintenance and operation
            of the Building), including, without limitation those incurred in

            made in connection with preparing space for any tenant or occupant
            or renovating space for any existing tenant or occupant, including
            permit, license and inspection fees and any contribution by Landlord
            to the cost of any such improvements, installations and decorations;

                  (12) financing and refinancing costs; and any costs incurred
            in connection with the sale of the Building or the making or

      under this Article 4 have been resolved. Notwithstanding the foregoing,
      the Record Retention Deadline with respect to the Base Year shall mean the

      however, that in no event shall the Records Retention Deadline with
      respect to the Base Year occur until all disputes relative to the Base
      Year timely commenced by Tenant under this Article 4 have been resolved.

            4.2 Additional Rent. Tenant shall pay, as Additional Rent, in
respect of each Lease Year:

            Costs for such Lease Year over Operating Costs for the Base Year;
            and

            Lease Year; provided, however, that if during such Lease Year the

            shall change the amount referred to in this clause (c) shall be
            computed separately for each portion of such Lease Year.

            If the Real Estate Taxes for any Lease Year or part thereof shall be
reduced after a payment therefor shall have been made by Tenant in respect of
that Lease Year pursuant to this Section, Landlord shall credit to Tenant an
amount equal to the product obtained by multiplying Tenant's Proportionate Share
by the net refund of the Real Estate Taxes received by Landlord (after
deduction, to the extent not previously paid by Tenant, of Tenant's
Proportionate Share of expenses, including fees and expenses of counsel and
experts, incurred by, or reimbursable by, Landlord in connection with reducing
the assessed valuation for the Building or the Land and in obtaining any
reduction or refund of the Real Estate Taxes) to the extent that the amount
otherwise payable pursuant to this Article for that Lease Year by Tenant would
have been less if the reduction in Real Estate Taxes had occurred during the
Lease Year; provided, however, that if the amount of such credit to which Tenant
is entitled shall exceed $100,000 Landlord shall, if Tenant shall so request,
refund the same within ten (10) days of such request.

            4.3 Payments on Account. In order to provide for current payments on
account of Additional Rent payable to Landlord pursuant to this Article for any
Lease Year, Tenant agrees to make estimated payments on account of the
Additional Rent for and during each Lease Year in twelve (12) monthly
installments. Each such installment shall be in an amount equal to 1/12th of the
amount payable by Tenant to Landlord pursuant to Section 4.2 for the preceding
Lease Year and such additional amount as reasonably estimated by Landlord,
except that

                  (i) Tenant's estimated payments in respect of its liability
            under clauses (a) and (b) of Section 4.2 for the first Lease Year
            after the Base Year shall be based on Landlord's good faith estimate
            of such liability, and

                  (ii) Tenant's estimated payments in respect of its liability
            under clause (c) of Section 4.2 for the first Lease Year shall be
            based on Landlord's good faith estimate of such liability,

                  (iii) in any subsequent case, Tenant's estimated payments
            shall not exceed by more than 5% the amount of Tenant's liability
            under Section 4.2 for the most recent previous Lease Year for which
            an Escalation Statement was furnished by Landlord to Tenant.

            4.4 Escalation Statement. Promptly after the end of any Lease Year
Landlord shall furnish Tenant with an Escalation Statement for such Lease Year.
If, as reflected in the Escalation Statement for any Lease Year, the amount of
Additional Rent payable by Tenant to Landlord pursuant to this Article for such
Lease Year shall be greater than (resulting in an underpayment) or be less than
(resulting in an overpayment) the total of all the installments/estimated
payments paid on account to Landlord by Tenant for the Lease Year, then,
promptly after receipt of the Escalation Statement for that Lease Year, Tenant
shall, in case of an underpayment, pay to Landlord the amount of the
underpayment


                                       17
   29

or Landlord shall,  in case of an overpayment,  credit to Tenant the amount of
the overpayment.

            4.5 Audit, etc. During the Audit Period with respect to any
Escalation Statement, Landlord shall permit all books and records of Landlord
and its managing agent relative to Real Estate Taxes, Operating Costs and
Cleaning Costs for the Lease Year to which such Escalation Statement shall
relate to be examined (and photocopied at Tenant's expense) by an officer of
Tenant or by an independent certified public accountant designated by Tenant for
the purpose of substantiating Landlord's determination of the amounts set forth
in such Escalation Statement. Landlord shall preserve such records until the
Record Retention Deadline with respect to the Lease Year to which such
Escalation Statement shall relate. Tenant shall keep all information obtained by
it pursuant to this Section 4.5 confidential other than any disclosures to
accountants, attorneys or other advisors or otherwise in connection with its
activities under this Section 4.5 or as required by law.

            If during the Audit Period Tenant shall notify Landlord that Tenant
disputes the correctness of such Escalation Statement (and include in such
notice a statement of its reasons therefor) (such notice being herein called an
"Additional Rent Dispute Notice"), the parties shall make a good faith effort to
resolve their differences within thirty (30) days after Landlord's receipt of
Tenant's notice of dispute. If they are unable to do so, then either party shall
have the right to refer such dispute to arbitration as provided in Article
Thirty-Five. If and to the extent such dispute is resolved in Tenant's favor
Tenant shall be entitled to a refund of its overpayment, together with interest
at a rate per annum equal to the prime commercial lending rate (as published
from time to time by The Wall Street Journal) plus 2% but not in excess of the
amount permitted by law (the "Interest Rate") on the overpayment, from July 1 of
such Lease Year to the date of refund.

            4.6 Base Year Statement. On or before the delivery to Tenant of the
Escalation Statement for Lease Year 2000, Landlord shall also deliver a
reasonably detailed statement of Real Estate Taxes for the Base Year and the
Operating Costs for the Base Year in form reasonably acceptable to Tenant (the
"Base Year Statement") and the Escalation Statement for the Lease Year 2000
shall not be deemed delivered unless accompanied by such Base Year Statement.
Subject to the provisions of Section 4.7, the Base Year Statement shall be used
to determine Tenant's liability under this Article 4 with respect to all Lease
Years during the initial term of this Lease.

            4.7 Base Year Audit, etc. During the Audit Period relative to the
Escalation Statement relating to Lease Year 2000, Landlord shall permit all
books and records of Landlord and its managing agent relative to Real Estate
Taxes and Operating Costs for the Base Year to be examined (and photocopied at
Tenant's expense) by an officer of Tenant or by an independent certified public
accountant designated by Tenant for the purpose of substantiating Landlord's
determination of the amounts set forth in the Base Year Statement. Landlord
shall preserve such records until the Record Retention Deadline with respect to
the Base Year. Tenant shall keep all information obtained by it pursuant to this
Section 4.7


                                       18
   30

confidential other than any disclosures to accountants, attorneys or other
advisors or otherwise in connection with its activities under this Section 4.7
or as required by law.

            If during the Audit Period relative to the Escalation Statement
relating to Lease Year 2000 Tenant shall notify Landlord that Tenant disputes
the correctness of the Base Year Statement (and include in such notice a
statement of its reasons therefor), the parties shall make a good faith effort
to resolve their differences within thirty (30) days after Landlord's receipt of
Tenant's notice of dispute. If they are unable to do so, then either party shall
have the right to refer such dispute to arbitration as provided in Article
Thirty-Five. If the Base Year Statement is corrected pursuant to this Section
4.7, the Base Year Statement as so corrected shall be used to determine Tenant's
liability under this Article 4 with respect to all Lease Years during the
initial term of this Lease.

            4.8 Excess Cleaning Costs. If, for any Lease Year during which
Tenant is cleaning any portion of the Premises pursuant to clause (a) of the
first paragraph of Section 11.7, Landlord can establish to Tenant's reasonable
satisfaction that

                  (a) the quotient of (i) the Cleaning Costs for such Lease
            Year, divided by (ii) the Landlord Cleaned Building Area for such
            Lease Year, exceeds

                  (b) what such quotient would have been if Landlord had
            cleaned, and the Landlord Cleaned Building Area had been, all of all
            of the office floors of the Building above the mezzanine

(such excess as Landlord is able so to establish being herein called the "Excess
Cleaning Cost") then, in respect of such Lease Year, Tenant shall pay Landlord,
as Additional Rent, an amount (the "Cleaning Payment") equal to the product of

                  (i) the excess of the Landlord Cleaned Building Area for such
            Lease Year over the Landlord Cleaned Premises Area for such Lease
            Year, multiplied by

                  (ii) the Excess Cleaning Cost (but not more than $.15 per
            square foot of rentable area per annum);

provided, however, that if during such Lease Year the Landlord Cleaned Premises
Area or the Landlord Cleaned Building Area shall change then the foregoing
provisions of this paragraph shall be applied separately to each portion of such
Lease Year and the Cleaning Payment for such Lease Year shall be the aggregate
thereof for each such portion. Tenant shall make the Cleaning Payment to
Landlord within thirty (30) days of the submission to Tenant of the Escalation
Statement for such Lease Year accompanied by Landlord's bill therefor the
Cleaning Payment (which shall include a statement in reasonable detail of the
derivation of the Cleaning Payment) and reasonably detailed supporting
documentation establishing the Cleaning Payment to Tenant's reasonable
satisfaction. Notwithstanding


                                       19
   31

Landlord's having established the Cleaning Payment to Tenant's reasonable
satisfaction, all of the provisions of Section 4.5 shall be applicable to this
Section 4.8, mutatis mutandis.

            Article 5. Use of Premises.

            5.1 The Premises shall only be used for general and executive
offices (including trading operations) and uses incidental thereto, including
the following incidental uses (i) conference and meeting facilities, including
places of assembly, (ii) computer and data processing, (iii) photocopying, (iv)
printing, (v) food preparation and service (including kitchens and kitchenettes,
pantries, dining rooms, cafeterias and vending machines), (vi) a health and
medical facility, (vii) an exercise and recreation facility, (vii) storage, (ix)
installation of equipment, and (x) support and utility functions; provided,
however, that the Special Purpose Areas may also be used for the purposes for
which the same are now being used. Tenant shall not use, or suffer or permit the
use of, the Premises or any part thereof for any other purpose.

            Landlord represents and warrants that attached hereto as Exhibit F
is a true and correct copy of the Certificate of Occupancy for the Building as
in effect on the date hereof.

            If pursuant to Applicable Law, Tenant cannot use any portion of the
Premises for any of the uses referred to above without amending the Certificate
of Occupancy for the Building to permit such portion of the Premises to be used
for such use, then

                  (i) Landlord shall (a) cooperate with Tenant as necessary or
            appropriate in order to obtain such amendment to such Certificate of
            Occupancy, and (b) within two (2) business days of Tenant's request,
            execute any application or other documents necessary or appropriate
            in order to obtain such amendment to such Certificate of Occupancy
            (and, in such a case, Tenant shall reimburse Landlord within twenty
            (20) days of demand for any out-of-pocket costs incurred by Landlord
            for review by an independent architect or engineer of any such
            application or other documents);

                  (ii) if, in order to obtain such amendment to such Certificate
            of Occupancy, it shall be necessary to remove any violations noted
            against the Building (other than any violations which pursuant to
            this Lease are the responsibility of Tenant), Landlord shall,
            promptly after Tenant's request, remove such violation, and if
            Landlord shall fail to do so within twenty (20) days of Tenant's
            request, Tenant may do so and recover the costs of doing so pursuant
            to Article 39.

            If pursuant to Applicable Law in effect on the date hereof, Tenant
cannot use or continue to use any portion of the Special Purpose Area for the
use for which it is now


                                       20
   32

used (an "Existing Special Purpose Area Use") without amending the Certificate
of Occupancy for the Building to permit such portion of the Special Purpose Area
to be used for such use, then (A) clause (i) and (ii) above shall apply (except
that the parenthetical provision of clause (i) shall not be applicable) and (B)
if, in order to obtain such amendment to such Certificate of Occupancy, it shall
be necessary to comply with any requirements of Applicable Law (other than any
compliance which pursuant to this Lease it is Tenant's responsibility to
effect), Landlord shall, promptly comply with such requirement of Applicable
Law, and if Landlord shall fail to do so within twenty (20) days of Tenant's
request, Tenant may do so and recover the costs of doing so pursuant to Article
39.

            5.2 Tenant shall not use, or knowingly suffer or permit the use of,
the Premises or any part thereof in any manner or for any purpose or do, bring
or keep anything, or knowingly suffer or permit anything to be done, brought or
kept, therein that would (a) violate any covenant, agreement, term, provision or
condition of this Lease or be unlawful or, subject to Section 5.1 above, be in
contravention of the Certificate of Occupancy for the Building, or (b) except as
permitted by this Lease, unreasonably interfere with the use and enjoyment of
the common areas and facilities of the Building by other occupants of the
Building.

            5.3 Tenant will not use, or knowingly suffer or permit the use of,
the Premises or any part thereof for any of the following purposes, whether or
not incidental to Tenant's business, namely:

                  (i) manufacturing of any kind,

                  (ii) the retail sale to persons visiting the Premises of any
            item whatsoever,

                  (iii) an auction of any kind (other than an auction incident
            to Tenant's business or by telephone or other electronic means),

                  (iv) the preparation, dispensation or consumption of food or
            beverages (other than to Tenant, other occupants of the Premises and
            their employees, clients and guests),

                  (v) as a school or classroom (other than for the use of
            Tenant, other occupants of the Premises and their employees, clients
            and guests),

                  (vi) as a medical or dental office (other than for the use of
            Tenant, other occupants of the Premises and their employees),

                  (vii) as an employment or travel agency (other than a travel
            agent servicing Tenant, other occupants of the Premises and their
            employees),


                                       21
   33

                  (viii) as retail banking facilities (which term shall exclude
            any ATM installed in the Premises), and

                  (ix) for the conduct of any disreputable activities.

Further, the Premises may not be used or occupied by any agency, department or
bureau of the United States government, any state or municipality within the
United States or any foreign government, or any political subdivision of any of
them, or any charitable, religious, union or other not-for-profit organization,
or any tax exempt entity within the meaning of the Internal Revenue Code of
1986, as amended (a "Prohibited Occupant"). Landlord shall not lease any space
in the Building to, or suffer or permit any space in the Building to be used or
occupied by, any Prohibited Occupant.

Notwithstanding the foregoing provisions of this Section 5.3, Tenant shall have
the right, subject to the other applicable terms of this Lease, to permit other
companies (whether or not they occupy space in the Building) to use Tenant's
meeting and training rooms and facilities (including the Picker Auditorium) and,
in connection therewith, to use Tenant's food service and consumption
facilities. Tenant may charge for such use and such use shall not be subject to
the provisions of Article 12 of this Lease.

            5.4 If any governmental license or permit (other than a certificate
of occupancy) shall be required for the proper and lawful conduct of any
business or other activity carried on in the Premises, and, if the failure to
secure such license or permit would in any way affect Landlord or the Building,
Tenant, at its expense, shall procure and thereafter maintain the license or
permit, submit the license or permit to inspection by Landlord, and comply with
the terms and conditions thereof.

            Article 6. Alterations by Tenant.

            6.1 In General. Subject to and in accordance with this Article 6 and
the other applicable provisions of this Lease, Tenant shall have the right, from
time to time, to make Alterations (as such term is defined in Section 7.1(e)) in
and to the Premises and the other areas of Building in which, pursuant to any of
the provisions of this Lease, Tenant is authorized to place or install property
or perform work. Without limiting the generality of the foregoing, it is
specifically agreed that, subject to compliance with the applicable provisions
of this Lease, Tenant shall have the right

                  (a) to reinforce floors and columns, including the
            reinforcement of columns necessary or appropriate to support
            Tenant's installations pursuant to Article 36 generally as described
            on Exhibit G;

                  (b) to make slab cuts for the purpose of installing stairs and
            running risers and conduits and to make beam cuts;


                                       22
   34

                  (c) to remove existing stairs and to fill in existing slab
            cuts (it being specifically agreed that from and after the Term
            Commencement Date Tenant may remove the interconnecting stairs
            between floors 11, 12 and 13 and fill-in the existing slab cuts
            notwithstanding that one or more of such floor may not yet have been
            delivered to Tenant);

                  (d) to install stone floors and/or raised floors, including in
            either case, if Tenant shall so elect, raising the level of the
            elevator stops and core areas to match such raised floors;

                  (e) to install additional toilets, showers and other plumbing
            facilities;

                  (f) to use BX cable rather than rigid conduit whenever
            permitted by applicable law; and

                  (g) to install a derrick and/or a Chicago boom in connection
            with Tenant's work under Article 36 (it being hereby confirmed that
            the installation of any such derrick or boom shall constitute an
            Alteration).

            6.2 Landlord's Approval in Certain Cases. Notwithstanding the
foregoing, Tenant shall not commence or perform

                  (i) any structural Alteration,

                  (ii) any Alteration which affects the operation of the systems
            of the Building outside of the Premises,

                  (iii) any Alteration to or which affects any portion of the
            Building outside of the Premises, or

                  (iv) any Alteration (or series of related Alterations) the
            cost of which on any floor of the Building is greater than Five
            Hundred Thousand ($500,000) Dollars

unless (a) Tenant shall have submitted to Landlord complete architectural and
engineering working drawings and specifications prepared, at Tenant's expense,
by a competent architect or engineer licensed in the State of New York ("plans
and specifications"), and (b) Landlord shall have approved such plans and
specifications.

            Landlord shall not unreasonably withhold such approval and shall
grant or deny such approval (including with any denial a reasonably detailed
statement of the reasons therefor) within


                                       23
   35

                  (a) ten (10) business days in the case of the initial
            submission of plans and specifications with regard to any Alteration
            referred to in clause (i), (ii) and (iii) above), or

                  (b) five (5) business days in the case of any resubmission of
            plans and specifications with regard to any Alteration referred to
            in clause (i), (ii) or (iii) above or in the case of any submission
            of plans and specifications with regard to any Alteration referred
            to in clause (iv) above.

If Landlord shall fail timely to disapprove any plans and specifications in
accordance with this Section 6.2 (including the required statement of reasons)
Landlord shall be deemed to have approved the same.

            Any approval by Landlord shall not be deemed to be a representation
or warranty that the approved work is properly designed to perform the function
for which it is intended or complies with any Applicable Law.

            6.3 Governmental Permits and Licenses. Tenant shall obtain all
governmental permits, licenses and approvals required in connection with any
Alterations performed or proposed to be performed by Tenant. Landlord shall,
within two (2) business days of Tenant's request, execute any permit, license or
approval application or any similar document required to be executed by Landlord
in connection with Tenant's obtaining any such permit, license or approval. In
case of any Alteration subject to Section 6.2, Landlord shall execute such
application or document notwithstanding its not having received or approved the
plans and specifications therefor, but Landlord's execution of such application
or document shall not constitute Landlord's approval of such plans and
specifications or a waiver of Landlord's rights under Section 6.2 with respect
thereto.

            6.4 Tenant's Contractors. Subject to the provisions of Section
7.1(e), Tenant shall have the right to use contractors of its choice for
performance of any Alterations; provided, however, that Tenant's mechanical,
electrical, plumbing and fire life safety contractor ("Critical Trade
Contractors") shall be subject to Landlord's prior approval. Landlord shall not
unreasonably withhold such approval and shall grant or deny approval within five
(5) business days of Tenant's request therefor. If Landlord shall fail timely to
deny approval, it shall be deemed to have granted approval. Any Critical Trade
Contractor approved by Landlord shall remain approved with respect to the
Alteration in question and subsequent Alterations until Landlord shall by notice
to Tenant revoke such approval, but no such revocation shall be effective with
respect to the Alteration in question or any subsequent Alterations for which
such Critical Trade Contractor was retained prior to such revocation. Landlord
hereby approves the Critical Trade Contractors listed on Exhibit H hereto. As
used in this Lease (relative to Landlord or Tenant), the term "contractors" or
"contractor" (but not the phrase "general contractor") shall also include
subcontractors or subcontractor.


                                       24
   36

            6.5 Performance of Alterations. Tenant will use reasonable efforts
in performing Alterations to avoid unreasonable interference with the occupants
of other parts of the Building, and shall perform the following work during
non-Business Hours, if so requested by Landlord: (a) demolition on any floor
immediately above or immediately below a floor occupied by any other tenant of
the Building, or (b) core drilling and chopping or chasing of concrete. Tenant
shall, at its sole cost and expense, repair all structural and mechanical parts
of the Building and the systems of the Building that shall be damaged by
Tenant's performance of Alterations, subject to the release provisions of
Section 22.6. Tenant shall comply with all Applicable Laws relative to the
performance by it of any Alterations. Tenant shall cause its contractors to
maintain workmen's compensation insurance as required by law and shall cause its
general contractor to maintain public liability insurance as may be reasonably
required by Landlord.

            6.6 Mechanics Lien. Tenant shall not do or fail to do any act that
shall or may render the Building subject to any mechanic's lien or other lien
and if any lien or liens are filed against the Building arising out of any
Alterations undertaken by Tenant, Tenant shall, at its sole cost and expense,
promptly remove the lien or liens of record within thirty (30) days after the
earlier of demand by Landlord or the receipt of notice by Tenant from the lienor
or anyone else concerning the filing of the lien or liens. If Tenant shall fail
to timely remove such lien or liens, Landlord may cause such lien or liens to be
removed of record by payment, bond or otherwise, as Landlord may elect, and
Tenant shall reimburse Landlord, as Additional Rent, for all reasonable costs
and expenses incidental thereto (including, without limitation, legal fees).

            Article 7. Various Covenants.

            7.1 Tenant's Covenants. Tenant shall:

            (a) take good care of the Premises, keep clean the portions of the
      Premises that Landlord is not required by this Lease to clean, and,
      subject to the release provisions of Section 22.6, pay the cost of making
      good any injury, damage or breakage to the Building or the Premises done
      by Tenant or by the employees, agents, licensees or invitees of Tenant;

            (b) observe and comply with the rules and regulations annexed hereto
      as Exhibit I and any other and further reasonable rules and regulations
      that Landlord hereafter at any time may make and communicate to Tenant,
      and that, in the reasonable judgment of Landlord, shall be necessary or
      desirable for the safety, care or appearance of the Building, or the
      preservation of good order therein, or the operation or maintenance of the
      Building, or the equipment thereof, or the comfort of tenants or others in
      the Building; provided, however, that in the case of any conflict between
      the provisions of this Lease and any rule or regulation, the provisions of
      this Lease shall control and provided, further that (i) Landlord will
      enforce all rules and regulations uniformly against all tenants, including
      Tenant, and


                                       25
   37

      (ii) so long as the area of the portion of the Premises not sublet (other
      than to pursuant to Section 12.7 and 12.8) shall exceed 250,000 rentable
      square feet, Landlord will not make any such other or further rule or
      regulation without the consent of Tenant, which consent, provided that
      such other or further rule or regulation does not, other than to a di
      minimis extent, affect Tenant's conduct of business or Tenant's rights and
      obligations under this Lease, shall not be unreasonably withheld and, if
      Landlord includes the following legend at the top of its request for
      consent "THIS REQUEST FOR CONSENT IS MADE PURSUANT TO SECTION 7.1(b) OF
      YOUR LEASE; IF YOU DO NOT DENY CONSENT WITHIN TEN (10) BUSINESS DAYS OF
      YOUR RECEIPT HEREOF YOU SHALL BE DEEMED TO HAVE GRANTED CONSENT" shall be
      deemed granted ten (10) business days after Tenant's receipt of Landlord's
      request for Tenant's consent unless Tenant notifies Landlord of its denial
      and the reasons therefor within that period of time;

            (c) permit Landlord, and any mortgagee under any Underlying
      Mortgage, and any lessor under any Underlying Lease, and their
      representatives, to enter the Premises (i) in an emergency, at any time
      and without notice, and (ii) otherwise, following reasonable notice at
      such hours as shall not materially interfere with the conduct of Tenant's
      business in the area entered, for the purposes of inspection, and permit
      them or any of their agents or contractors to enter the Premises (i) in an
      emergency, at any time and without notice, and (ii) otherwise, following
      reasonable notice at such hours as shall not materially interfere with the
      conduct of Tenant's business in the area entered, for the purpose of
      complying with any Applicable Law, or exercising any right reserved to
      Landlord in any other provision of this Lease, and permit Landlord,
      following reasonable notice, to show the Premises at reasonable times
      during Business Hours (or non-Business Hours if entry during Business
      Hours would materially interfere with the conduct of Tenant's business) to
      any mortgagee under any Underlying Mortgage, any lessor under any
      Underlying Lease, or any prospective purchaser, lessee, mortgagee or
      assignee of any mortgage of the Building or the Land or of Landlord's
      interest therein, and their representatives, and during the period of
      twelve (12) months next preceding the date of expiration of the term
      hereof, to similarly show the Premises to any person contemplating the
      leasing of all or a portion thereof provided, however, that (a) except in
      the case of an emergency or as Tenant may otherwise permit, no individual
      shall be permitted to enter the Premises for purposes of performing any
      maintenance, repairs, alterations, cleaning or other services or work or
      related inspections or preparations, unless such individual has cleared

shafts, stairways, stacks, pipes, conduits, ducts, electric or other utilities,
sinks, fan rooms or other Building facilities, and the use thereof, as well as
access thereto through the Premises (subject to the provisions of Section
7.1(c)) for the purposes of the use, operation, improvement, replacement,
repair, maintenance and decoration thereof, are expressly reserved to Landlord.

            9.5 [Intentionally Omitted]

            9.6 Removal of Personal Property. Except as provided in Section 9.2,
at or prior to the Expiration Date or any earlier date upon which the term of
this Lease may expire or be terminated, Tenant shall remove from the Premises
all of its personal property. Any personal property that remains in the Premises
after the expiration or termination of the term of this Lease shall be deemed to
have been abandoned, and either may be retained by Landlord as its property or
may be disposed of at Tenant's expense in any manner that Landlord chooses.

            9.7 Holdover. If Tenant or Tenant's successors or assigns, whoever
is in possession, fails to vacate the Premises or any portion thereof on or
before the Expiration Date or other termination date of this Lease, such
continued use and occupancy of the Premises or such portion thereof shall
constitute a holdover under a month-to-month tenancy, in which event Tenant
shall be obligated to pay Landlord in advance on the first day of each month
with respect to all floors of the Premises which Tenant has not then completely
vacated (1) for the first ninety (90) days after the Expiration Date or other
termination date, a monthly fixed rental equal to one hundred fifty percent
(150%) of the aggregate of the Fixed Rent and the Additional Rent payable under
Article 4 for the last month of the term hereof and (2) thereafter a monthly
fixed rental equal to two hundred percent (200%) of the aggregate of the Fixed
Rent and the Additional Rent payable under Article 4 for the last month of the
term hereof. Tenant's liability under this Section 9.7 with respect to any floor
of the Premises shall terminate upon Tenant's vacation of such floor, but this
sentence shall not be deemed to release Tenant from any such liability under
this Section 9.7 with respect to such floor of the Premises accrued prior to
such vacation. The liability provided for in this Section 9.7 shall constitute
Landlord's sole remedy on account of any holdover by Tenant,


                                       35
   47

and Tenant shall not be liable for any damages arising out of such holdover, or
to indemnify Landlord on account of any Claim arising out of such holdover;
provided, however, that this sentence shall not prevent Landlord from
prosecuting any action or proceeding to recover possession of the Premises.

Article 10. Electric Current and Water.

            10.1 Base Electricity. Landlord shall furnish to the existing
electrical closets serving each floor of the Premises alternating electric
current in such amounts as Tenant shall from time to time draw or require;
provided, however, that Landlord shall not be required pursuant to this Section
10.1 to furnish alternating electric current in excess of 6 watts (demand) per
square foot of gross area of the Premises in the aggregate; provided, however,
that with respect to

                  (i) any of the Premises in the basement, the aforesaid amount
            shall be 8.3 watts (demand) per square foot of gross area,

                  (ii) any of the Premises on the 3rd floor, the aforesaid

                  (iii) any of the Premises on the 4th floor, the aforesaid
            amount shall be 12.8 watts (demand) per square foot of gross area,
            and

                  (iv) any of the Premises on the 41st floor, the aforesaid
            amount shall be 7.1 watts (demand) per square foot of gross area.

Tenant shall have the right to distribute the electrical current provided to it
under this Section 10.1 to the Premises (including transfers of electrical
current from one floor of the Premises to another) and to Tenant's installations
in, to, on or about the Building outside of the Premises. Tenant shall be
entitled to a key to the electrical closets on any floor all or any part of
which is included in the Premises.

            10.2 Supplemental Electricity. Landlord shall furnish to each of
Tenant's Dedicated Switches (as hereinafter defined) alternating electric
current in such amounts as Tenant shall from time to time draw or require;
provided, however, that Landlord shall not be required pursuant to this Section
10.2 to furnish alternating electric current to Tenant's Dedicated Switches in
excess of 2000 amperes (demand) per switch, 4000 amperes (demand) in the
aggregate. Landlord shall not be obligated to furnish alternating electric
current under this Section 10.2 until Tenant shall have performed the work
described in Section 10.5. Tenant shall have the right to distribute the
electrical current provided to it under this Section 10.2 through the electrical
risers or buses installed by it pursuant to Article 42 to the Premises and to
Tenant's installations in, to, on or about the Building outside of the Premises.


                                       36
   48

            10.3 Additional Electricity. If Tenant shall request or desire
alternating electrical current in excess of that to which it is entitled under
Section 10.1 and 10.2, then, subject to the provisions of this Section 10.3,
Landlord shall furnish the same; provided, however, that if, in Landlord's
reasonable judgment, such additional electric current cannot be furnished unless
additional panels, transformers, risers, conduits, feeders, switches,
switchboards and/or appurtenances ("Electrical Equipment") are installed in the
Building (a) Landlord shall not be required to furnish such additional electric
current until such additional Electrical Equipment is so installed, and (b)
Tenant shall be permitted, following written notice to Landlord, to install such
additional Electrical Equipment provided that the installation and use thereof
is permitted by Applicable Laws and shall not cause permanent damage or injury
to the Building or cause or create a dangerous or hazardous condition or entail
unreasonable alterations or unreasonably interfere with or disturb other tenants
or occupants of the Building (collectively, "Building Requirements"), and Tenant
shall pay all costs and expenses in connection with such installation.

            10.4 Character of Electricity. All alternating current finished by
Landlord pursuant to this Lease shall be furnished at nominal utility voltage
(265/460V with allowable fluctuations within regulatory agency requirements), 3
phase, 4 wire, with a power factor of 0.9. The electrical voltage and current
distortion at the service switchboards shall be within the limits stated in IEEE
519.

            10.5 Tenant's Dedicated Switches. The term "Tenant's Electrical
Work" shall mean

                  (i) modification of an existing switchboard as shown on
            Exhibit OO to accept two Switches in accordance with Applicable Law,

                  (ii) relocation of load from a Switch on switchboard B as
            shown on Exhibit OO to one of the two Switches on said modified
            existing switchboard, and

                  (iii) connection of (a) the Switch on switchboard B referred
            to in clause (ii) above, and (b) the other Switch on the existing
            modified switchboard to Tenant's load. (such two switches being
            herein called "Tenant's Dedicated Switches").

The term "Switch" shall refer to a switch rated a 2500 amperes fused at 2000
amperes (demand). Tenant shall have the right to perform Tenant's Electrical
Work and, if Tenant does so, Tenant shall be entitled to exclusive use of
Tenant's Dedicated Switches. Upon the completion of Tenant's Electrical Work,
Landlord shall cause alternating electrical current to be furnished to Tenant's
Dedicated Switches in accordance with Section 10.2.

            10.6 Electricity Supplier for the Building. Except to the extent
that Tenant shall otherwise consent from time to time or as otherwise provided
in this Lease, Landlord


                                       37
   49

shall continue to purchase all electricity to be used by Landlord, Tenant or any
other tenant or occupant of the Building ("Building Electricity") from
Consolidated Edison Corporation or its successor ("ConEd") pursuant to ConEd's
applicable tariff and not pursuant to any contract or contractual arrangement.

            Subject to the rights of any Building tenant under any lease now in
effect, Landlord shall not suffer or permit any tenant or occupant of the
Building (other than Tenant) to purchase electricity directly from ConEd or from
any other supplier (other than Landlord).

            If Tenant shall so request Landlord shall solicit competitive bids
from at least three qualified electricity suppliers selected by Landlord and any
other qualified electricity suppliers identified by Tenant for the providing of
Building Electricity and, after consulting with Tenant and obtaining Tenant's
approval as provided below, shall enter into an electricity supply contract for
the providing of Building Electricity with the electricity supplier who Landlord
reasonably believes to be most beneficial to the tenants of the Building taking
into account price and any other relevant considerations; provided, however,
that Landlord shall not enter into any electricity supply contract with any
electricity supplier without Tenant's prior written approval of such contract
and such supplier. If any such contract entered into by Landlord shall provide
for any rebates or other payments to Landlord then the amounts payable by Tenant
under this Article 10 and Operating Costs under Article 4 shall be computed
after deducting such rebates and other payments. Upon the expiration or other
termination of any electricity supply contract, unless Tenant shall have
directed Landlord to purchase electricity from ConEd, Landlord shall again
comply with the provisions of this paragraph. If Tenant shall fail to approve
any electricity supply contract or any electricity supplier (either initially or
subsequently upon expiration or termination of the preceding electricity supply
contract) or shall direct Landlord to purchase Building Electricity from ConEd,
Landlord shall do so in accordance with the first paragraph of this Section
10.6, subject to the renewed application of this paragraph if Tenant shall
subsequently so request.

            Landlord shall qualify and maintain qualification as a redistributor
of electricity under the applicable sales tax law, and, upon Tenant's request
from time to time, shall furnish to Tenant evidence that it has done so.

            10.7 Electricity Charges -- Average Cost per KWH. All electric
current consumed by Tenant shall be measured by a meter or meters provided and
installed by Landlord at its expense at a location or locations selected by
Landlord. Each meter measuring the electricity referred to in Section 10.1 shall
be located in the Building electrical closet on the floor in question. Each
meter measuring the electricity referred to in Section 10.2 shall be located in
the basement of the Building on or adjacent to the switchboard on which the
switch in question is located. Prior to installing any meter pursuant to this
paragraph, Landlord shall so notify Tenant and, if Tenant promptly so request,
Landlord shall install a meter of the type referred to in Section 10.8 rather
than a consumption-only meter and in such a case Tenant shall reimburse Landlord
for increased cost of purchase or


                                       38
   50

installation of such meter in excess of the cost of purchasing and installing a
consumption-only meter.

            Commencing on the Term Commencement Date and upon the Delivery Date
of each Applicable Portion, Tenant shall pay to Landlord, for each billing
period of the electricity supplier furnishing the Building Electricity (the
"Building Electricity Supplier"), an amount (the "Electric Charge") equal to the
product obtained by multiplying

                  (i) the actual number of kilowatt hours of electric current
            consumed by Tenant in the billing period, by

                  (ii) a fraction having as its numerator

                        (a) if ConEd shall be the Building Electricity Supplier,
                  the amount charged Landlord by ConEd pursuant to the
                  applicable tariff for Building Electricity for the billing
                  period including both the consumption charge (including fuel
                  adjustment) and the demand charge and all utility taxes, and
                  excluding all sales and use taxes whether or not separately
                  stated on the electric bill issued to Landlord,

                        (b) if ConEd shall not be the Building Electricity
                  Supplier, the sum of (i) the amount charged Landlord by the
                  Building Electricity Supplier pursuant to the electricity
                  supply contract entered into in accordance with this Lease for
                  Building Electricity for the billing period and (ii) the
                  amount charged Landlord by ConEd pursuant to the applicable
                  tariff for delivery to the Building of such Building
                  Electricity purchased from the Building Electricity Supplier
                  for the billing period, including, in both cases, both the
                  consumption charge (including fuel adjustment) and the demand
                  charge and all utility taxes, and excluding all sales and use
                  taxes whether or not separately stated on the electric bill
                  issued to Landlord,

            and having as its denominator the total number of kilowatt hours of
            Building Electricity consumed in the billing period.

Tenant shall also pay to Landlord any sales taxes on the Billing Period Electric
Charge payable by it pursuant to this Section, and Landlord shall remit such
sales tax to the appropriate governmental agency.

            If, with Tenant's prior consent, the Building Electricity shall be
purchased from more than one electricity supplier for any billing period, the
aforesaid fraction shall be computed by aggregating the amounts charged by and
the electricity furnished by such suppliers.


                                       39
   51

            As used in this Section 10.7, the phrase "the amount charged
Landlord by ConEd" or "the amount charged Landlord by the Building Electricity
Supplier" shall mean such amount as reduced by all abatements, reductions and
exemptions if, as and when in effect and applicable to the electricity to which
this Section shall relate.

            10.8 Electric Charges -- Actual Cost Contribution. By notice to
Landlord Tenant shall have the right to require that, in lieu of the amount
provided for in Section 10.7, the Electric Charge payable by Tenant be equal to
Tenant's actual contribution to the cost of Building Electricity ("Actual
Electric Cost Contribution"), considering consumption and demand (measured on a
co-incident demand basis) separately and, if Tenant shall so elect, considering
time of day; provided, however, that no such notice shall be effective unless
and until Tenant shall have installed in the Building such meters and other
equipment as are necessary to compute the Actual Electric Cost Contribution (the
"Additional Metering Equipment"). Tenant shall have the right to install the
Additional Metering Equipment in the Building. The demand component of the
Actual Electric Cost Contribution for any billing period shall be equal to the
ratio of Tenant's demand (measured on a co-incident demand basis) at the time of
the Building's peak demand for such billing period to the Building's peak demand
for such billing period, applied to the demand charge for such billing period.
The consumption component of the Actual Electric Cost Contribution for any
billing period shall be equal to the ratio of the Tenant's consumption for such
billing period to the Building's consumption for such billing period, applied to
the consumption charge (including fuel adjustment), and computed separately for
each applicable time of day, if applicable. The Actual Electric Cost
Contributions shall be computed exclusive of all sales and use taxes whether or
not separately stated on the electric bill issued to Landlord. Tenant shall also
pay to Landlord any sales taxes on the Electric Charge payable by Tenant
pursuant to this Section, and Landlord shall remit such sales tax to the
appropriate governmental agency. As used in this Section 10.8, the phrase "the
cost of Building electricity" shall mean such cost as reduced by all abatements,
reductions and exemptions if, as and when in effect and applicable to the
electricity to which this Section shall relate.

            10.9 Billing & Payment. Landlord shall pay all charges for all
Building Electricity and shall indemnify Tenant against any claims therefor.

            Landlord shall bill Tenant for the Electricity Charge, and the sales
and use tax thereon, monthly or at such other intervals as Landlord shall be
billed by the Building's Electricity Supplier. Each such bill shall be
accompanied by copies of the electric bills issued to Landlord on which it is
based, as well as records of the reading of the meters measuring Tenant's usage
and a statement showing the computation of the Electric Charge. Each such bill
rendered by Landlord in accordance with this Section shall be due and payable by
Tenant within twenty (20) days of presentation as aforesaid. If Tenant shall
dispute the amount of the Electric Charge for any billing period, and the
parties are unable to resolve such dispute within thirty (30) days of Tenant's
notice to Landlord thereof, such dispute shall be resolved by arbitration
pursuant to Article 35 and in any such arbitration the arbitrator shall be a
recognized electrical consultant practicing in New York City who shall have been


                                       40
   52

engaged in such practice for not less than ten (10) years. No such dispute shall
excuse Tenant from payment on the basis of Landlord's bill, but Tenant shall be
entitled to interest at the Interest Rate on any overpayment from the date of
overpayment to the date of refund.

            Landlord shall make available to Tenant from time to time upon
Tenant's request copies of all electricity billing records and meter and
submeter readings for the Building.

            10.10 Direct Service -- Illegality of Redistribution. If it shall
become illegal for Landlord to purchase and redistribute electric current to its
tenants, Landlord shall, upon not less than thirty (30) days' prior notice to
Tenant, discontinue the furnishing of electric current to Tenant and Tenant
shall contract for electric current with the electricity supplier of Tenant's
choice; provided, however, that

                  (a) Landlord shall permit Tenant to use any existing
            Electrical Equipment in the Building for the purpose of receiving
            such electric current from such supplier but only to the extent that
            the same is available, suitable and safely capable of supplying
            electric current to Tenant,

                  (b) if and to the extent that any additional Electrical
            Equipment is required to be installed in Building in order for
            Tenant to receive such electrical current (without reduction in
            capacity or diversity) Landlord shall install the same at its
            expense subject to Tenant's approval thereof (not to be unreasonably
            withheld), and

                  (c) Landlord shall not discontinue the furnishing of electric
            current to Tenant until (i) Tenant has concluded arrangements with
            Tenant's electric supplier, (ii) Tenant's electricity supplier has
            commenced to provide electric current to Tenant, and (iii) if any
            additional Electrical Equipment is required by clause (b) above to
            be installed, the same has been installed and placed in service.

            10.11 Direct Service--Tenant's Election. By notice to Landlord,
Tenant shall have the right (i) to purchase directly from the electricity
supplier of its choice any or all of the electric current otherwise required to
be furnished by Landlord pursuant to this Article 10 and (ii) for such purpose
to use any existing Electrical Equipment in the Building for the purpose of
receiving such electric current from such supplier but only to the extent that
the same is available, suitable and safely capable of supplying electric current
to Tenant; provided, however, that (a) Tenant shall not directly so purchase
electricity unless and until Tenant shall have installed in the Building any
additional Electrical Equipment necessary for Tenant to do so, and (b) Tenant
shall be required, at its expense, to maintain any such Electrical Equipment
used by Tenant pursuant to clause (ii) above or installed by Tenant pursuant to
clause (a) above. Tenant shall have the right to install in the Building such
additional Electrical Equipment as shall be necessary or appropriate in order
for Tenant to


                                       41
   53

receive such electrical current (without reduction in capacity or diversity)
directly from Tenant's electricity supplier.

            10.12 Tenant's Generator Plant -- Sale of Output. Tenant shall have
the right to sell the output of Tenant's Generator Plant to the purchaser of its
choosing (excluding Building tenants other than Tenant's subtenants), and to
install in the Building such additional Electrical Equipment as shall be
necessary for Tenant to do so; provided, however, that such additional
Electrical Equipment shall not adversely affect the Building's electrical system
or electric service to the Building or any of the other tenants therein.

and on which the Premises are, or any portion thereof is, located, and Landlord
shall keep all passenger elevators in service (and available to Tenant) at all
times (except for breakdown and scheduled service, repairs or other work which
shall be subject to Section 11.7).

            Landlord shall cause each passenger elevator to conform to the
performance specifications attached hereto as Exhibit L. No passenger elevator
shall, without Tenant's consent, be modified to serve any floor it does not
currently serve or to cease serving any floor it currently serves, except that

                  (i) Tenant shall have the right, from time to time, to control
            whether or not the low-rise and/or the mid-rise and/or the high-rise
            elevator bank shall serve the 16th floor and, if either the mid-rise

for so long as Tenant shall so request:

                  (i) one or both of such shuttle elevators (as Tenant shall
            request) shall be configured to serve or not serve such of the
            floors of the Building as it shall be capable of serving (as Tenant
            shall request), and/or

                  (ii) Tenant shall be provided with keys in order to call
            and/or operate one or both the shuttle elevators from or to any
            floor of the Building it shall be capable of serving;

provided, however, that (a) the shuttle elevators shall be subject to call for
ADA access at all times as required by Applicable Law, and (b) Tenant shall
reimburse Landlord for the actual cost of any additional security necessitated
by any shuttle elevator service requested by Tenant pursuant to clause (i) of
this sentence.

            (c) If Landlord shall install any card key or other security system
on any elevator the same shall be compatible with Tenant's key card.

shall be subject to Section 11.7) (i) two escalators between the plaza level and
the mezzanine level, and (ii) four escalators between the mezzanine level and
the 3rd floor of the Building (the "3rd Floor Escalators"); provided, however,
that

                  (A) prior to the Delivery Date of the 3rd/4th Floor Special
            Purpose Area, Landlord shall not be required to keep the 3rd Floor
            Escalators in service when none of the facilities on the 3rd floor
            are in use, and

                  (B) from and after the Delivery Date of the 3rd/4th Floor
            Special Purpose Area, (i) Tenant shall have the exclusive right to
            use and to control access to and to control the operation and hours
            of operation of the 3rd Floor Escalators, including the right to
            shutdown one or more of such 3rd Floor Escalators, and (ii) Tenant's
            right to use the 3rd Floor Escalators shall be exclusive, and (iii)
            Tenant shall reimburse Landlord for the actual cost of the
            Building's maintenance contract covering the 3rd Floor Escalators.

            (e) From and after the Delivery Date of the 3rd/4th Floor Special
Purpose Area, (i) Landlord shall keep in service (and available to Tenant
exclusively) at all times (except for breakdown and scheduled service, repairs
or other work which shall be subject to Section 11.7) the elevator serving only
the loading dock and the 2nd, 3rd and 4th floors ("Special Purpose Elevator"),
and (ii) Tenant shall reimburse Landlord for the actual cost of the Building's
maintenance contract covering the Special Purpose Elevator.

            (f) If for any Renewal Term the Premises shall not include the
3rd/4th Floor Special Purpose Area then (i) the provisions of clause (B) of the
proviso to Section 11.2(d) and the provisions of Section 11.2(e) shall be void,
and (ii) Landlord shall not be required to keep the 3rd Floor Escalators in

are, or any portion thereof is, located.

            Except for breakdown and scheduled service, repairs and other work
which shall be subject to Section 11.11, Landlord shall keep both such freight
elevators in service (and available to Tenant) on a non-exclusive basis at all
times during Freight Elevator Hours.

            If and for so long as Tenant shall be providing any cleaning under

                                       45
   57

            Freight, furniture, business equipment, merchandise and packages of
any description shall be delivered to and removed from the Premises only in the
freight elevators and through the service entrances and corridors.

            Notwithstanding the foregoing, Tenant shall be permitted to use the
passenger elevators for mail (including inter-office mail) delivery, courier
services (such as Federal Express and UPS) and messengers, provided that, if and
to the extent Tenant shall require the use of carts in connection therewith,
Tenant shall only use carts with bumpers which have been approved by Landlord,
such approval not to be unreasonably withheld, so as not to damage the passenger
elevator cars.

            11.4 Heating, Ventilating and Air-Conditioning. Landlord shall

                  (a) subject to any applicable regulations adopted by any
            governmental authority, supply heat to the Premises and the public
            portions of the Building during Business Hours when needed for
            comfortable occupancy, and

                  (b) subject to any applicable regulations adopted by any
            governmental authority, supply air conditioning and ventilation to
            the Premises and the public portions of the Building during Business
            Hours throughout the year.

Such heating, ventilating and air-conditioning shall provide:

                  (a) inside conditions of no more than 76 (+/-2) degrees F.
            d.b. (relative humidity of no more than 50%) so long as the outside
            conditions are not more than 95 degrees F. d.b. 75 degrees F. w.b.,
            except to the extent arising from occupancy of the Premises by more
            than one person per 100 usable square foot or average electricity
            consumption in the Premises of more than 3 watts (demand) per
            useable square foot;

                  (b) inside conditions of not less than 70 degrees F. d.b. (no
            minimum humidity) so long as the outside conditions are not less
            than 5 degrees F. d.b; and

                  (c) at least .87 cfm of conditioned air per useable square
            foot (including at least .15 cfm fresh air) supplied at no greater
            than 58 degrees F. d.b. at the take-offs on each floor with not less
            than 1.25 inches of residual static pressure as measured downstream
            of the floor shutoff/isolation dampers on both risers and as
            measured when such conditioned air is being provided to all floors
            of the Building; provided, however, that when the base building
            chiller plant is not in operation Landlord may supply air warmer
            than the aforesaid temperature provided that Landlord increases the
            quantity of air


                                       46
   58

            delivered so as to provide equivalent cooling in accordance with
            good operating practices.

Landlord shall maintain the heating, ventilation and air conditioning systems to
the Premises in good order and condition, except for damage occasioned by the
act of Tenant, which will be repaired by Landlord at Tenant's expense.

            11.5 Supplemental Condenser Water. Landlord shall furnish to Tenant,
at all times, from the Building's condenser water system such condenser water as
Tenant shall from time to time draw for Tenant's supplemental cooling
requirements up to the Tenant's Building Condenser Water Quantity (as
hereinafter defined) of condenser water. Landlord shall furnish such condenser
water at a maximum entering water temperature of 85 degrees Fahrenheit, and
Tenant's condenser water-using equipment may cause such temperature to rise to a
maximum of 100 degrees Fahrenheit. Such condenser water shall be furnished
through the Building's condenser water riser to each floor on which the Premises
are located.

            Initially Tenant's Building Condenser Water Quantity shall be 200
tons; provided, however, that by notice to Landlord given from time to time
Tenant may increase or decrease Tenant's Building Condenser Water Quantity;
provided, however, that except for any increase notice of which is given by
Tenant within 180 days of the commencement of the term of this Lease with
respect to any Accepted Offer Space and which is limited to the tonnage of
condenser water being delivered to such Accepted Offer Space prior to Tenant's
leasing the same, any such increase shall be subject to Landlord's having, at
the time of Tenant's notice of increase, such increase available.

            Tenant shall pay, as additional rent to Landlord, within thirty (30)
days of being billed therefor, the Applicable Price for each ton of Tenant's
Building Condenser Water Quantity; provided, however, that for the period
commencing on the Term Commencement Date and ending on the date six (6) months
after occupancy for the conduct of business of the last of the Premises
described in Exhibit C to be occupied by Tenant, such charge shall be computed,
rather than by reference to Tenant's Building Condenser Water Quantity, by
reference to the condenser water-using equipment actually installed by Tenant
and serving the portions of the Premises in which Tenant shall have opened for
the conduct of business. There shall be no additional "tap-in" or other fees.
The charges under this paragraph shall be adjusted upon any increase or decrease
in Tenant's Building Condenser Water Quantity (and, during the period described
in the proviso the preceding sentence, upon Tenant commencing to occupy any
Applicable Portion for the conduct of business).

            11.6 Cleaning By Landlord. Landlord shall clean the following areas
of the Building in accordance with the cleaning specifications annexed hereto as
Exhibit M:

                  (a) the common areas of the Building on or below the mezzanine
            level of the Building, the fire stairs of the Building, and the
            windows of the Building (both the interior and exterior thereof);


                                       47
   59

                  (b) all portions of the Premises (and all common areas of the
            Building) that are located on any Partial Premises Floor; and

                  (c) during any period for which Tenant, in accordance with the
            provisions of Section 12.3, has requested that Landlord clean all
            portions of the Premises (and all common, service and utility areas
            of the Building) that are located on any Full Premises Floor, all
            portions of the Premises (and all common, service and utility areas
            of the Building that are located on such Full Premises Floor;

provided, however, that Landlord shall not be required to clean (i) any portion
of the Premises below the mezzanine level of the Building, or (ii) any portion
of the Premises that is used for preparing, dispensing or consuming food or
beverages or for storage or as an exhibition area or classroom, or as a shipping
room, mail room or for similar purposes or that is a toilet (other than the
toilets located in the core of the Building) or a shop or that is used for the
operation of computers (other than personal computers or similar equipment),
data processing, reproduction, duplicating or similar equipment or any portion
of the Premises designated by Tenant as a Secure Area under Section 7.1(c) (the
portions referred to in this clause (ii) being herein called the "Excluded
Cleaning Areas")).

            With respect to the cleaning provided by Landlord under this Section
11.6, Landlord shall provide to Tenant, not less frequently than quarterly, an
advance schedule of the days on which each of the periodic non-daily cleaning
services referred to in Exhibit M will be furnished to each floor of the
Premises and each portion of the common areas of the Building.

            With respect to the cleaning provided by Landlord under this Section
11.6, Tenant shall pay to Landlord, Landlord's actual cost under Landlord's
cleaning contract, of any additional cleaning of the Premises required because
of the carelessness of Tenant.

            Upon the conversion of any floor of the Building from a Partial
Premises Floor to a Full Premises Floor (i.e. upon the commencement of the term
of this Lease with respect to the last portion of the leasable area of such
floor) Landlord shall cease to clean such floor, subject to the provisions of
clause (i) of Section 11.7 below.

            11.7 Cleaning By Tenant. Subject to the provisions of this Section
11.7, Tenant shall clean (a) all portions of the Premises (and all common areas
of the Building) located on any Full Premises Floor at least in accordance with
the applicable portions of the cleaning specification annexed hereto as Exhibit
M, and (b) all Excluded Cleaning Areas; provided, however, that upon not less
than 90 days prior notice to Landlord from time to time Tenant


                                       48
   60

                  (i) may request that Landlord clean all portions of the
            Premises (and all common areas of the Building) on any Full Premises
            Floor (and commencing upon the lapse of such 90 days (or such longer
            period as shall be provided in Tenant notice under this clause (i))
            such floor shall be cleaned pursuant to Section 11.6, rather than
            this Section 11.7, and

                  (ii) may request that Landlord cease to clean all portions of
            the Premises (and all common areas of the Building) on any Full
            Premises Floor (and commencing upon the lapse of such 90 days (or
            such longer period as shall be provided in Tenant's notice under
            this clause (ii)) such floor shall again be cleaned pursuant to this
            Section 11.7, rather than Section 11.6.

            Tenant shall deposit its refuse and rubbish in the freight elevator
lobby of each Full Premises Floor which it is cleaning pursuant to this Section
11.7, and Landlord shall remove such rubbish nightly on Business Days.

            11.8 Cooperation in the Selection of Cleaning Contractors. Landlord
and Tenant shall endeavor to cooperate with one another with respect to the
solicitation of bids for cleaning services to be provided by Landlord under
Section 12.2 and Tenant under Section 12.3; provided, however, that each party
shall have (i) the right to control the bidding procedures to be used by it
(and, in the case of Tenant, the right to award the contract without bidding)
and the terms and conditions of the cleaning contract to be entered into by it,
and (ii) to retain the cleaning contractor of its choice subject, in Tenant's
case, to the provision of Section 7.1(e). Subject to the foregoing, Landlord and
Tenant agree to solicit bids for the initial cleaning contract from the cleaning
contractors listed on Exhibit N.

            11.9 Rubbish Removal. Landlord shall remove the refuse and rubbish
from each floor of the Premises and the Building nightly on Business Days;
provided, that in the case of any Full Premises Floor being cleaned by Tenant
pursuant to Section 11.7 Tenant shall have placed the same in the freight
elevator lobby. Tenant shall pay to Landlord, Landlord's actual cost under
Landlord's cleaning contract, of the removal from the Premises and the Building
of any of Tenant's refuse and rubbish in excess of that incident to normal
office occupancy, except wastepaper baskets left for emptying as an incident to
Landlord's normal cleaning of the Premises.

            11.10 Additional Services. Landlord shall, when and to the extent
requested by Tenant upon advance notice not later than (x) 3:00 P.M., in case of
service on days other than Saturdays, Sundays and Holidays, (y) 12:00 P.M. on
Friday in case of service on Saturdays or Sundays and (z) 12:00 P.M. on the
business day preceding a Holiday in the case of service on a Holiday, furnish
(i) additional freight elevator (and loading dock) service on a dedicated basis,
(ii) additional heating, air conditioning, ventilation services, (iii)
additional cleaning services, and (iv) other additional services as listed on
Exhibit O annexed hereto, and Tenant, within twenty (20) days of Landlord's
bills therefor, shall pay Landlord the Applicable Price therefor. There shall be
no additional charge to Tenant for Tenant's use,


                                       49
   61

during Freight Elevator Hours, of the freight elevators to bring in construction
materials for the performance of Alterations or for Tenant's move in to any
portion of the Premises. During construction of Alterations and move-in, Tenant
will have the dedicated use of one (1) freight elevator at such times as Tenant
shall request, to be manned at such times by Landlord's own union labor;
provided, however, that (i) Tenant shall reimburse Landlord for Landlord's
actual out-of-pocket cost of furnishing such Landlord's own union labor, (ii) if
the use of Landlord's own union labor shall result in any labor trouble or
jurisdictional dispute with the union labor of Tenant's contractors, the freight
elevator shall instead be manned by union labor furnished by Tenant's
contractor, and (iii) Tenant shall not be entitled to such dedicated use of one
(1) freight elevator during any periods of breakdown of the Building's other
freight elevator. In addition, during such construction, Tenant may have the
exclusive use of one (1) passenger elevator from each bank for the transport of
its construction personnel only (but not construction materials). Tenant shall
be responsible for daily cleaning and maintenance of such elevator, the public
lobby and any other area of the Building (as opposed to the Premises) affected
thereby. During all other times, if Tenant requests temporarily the dedicated
use of one (1) freight elevator, Landlord shall furnish the same and Tenant
shall pay to Landlord the Applicable Price for such service. During its move-in
Tenant shall have the right to use the passenger elevators in the low rise
elevator bank for its move provided Tenant properly protects such elevators.
Following Tenant's performance of the initial Alterations with respect to any
portion of the Premises, Landlord shall clean such portion of the Premises to
prepare the same for Tenant's occupancy, at no additional cost to Tenant,
provided that such portion is free of construction materials and debris.

            11.11 Interruption in Services. Landlord reserves the right, without
any diminution or abatement of rent or any other liability to Tenant, including,
without limitation, for direct or consequential damage, or otherwise, and
without constituting any claim of constructive eviction, to stop any heating,
elevator, escalator, ventilation, air conditioning, electricity, domestic water,
condenser water, cleaning or other service and to interrupt the use of any
Building facilities, when necessary, and for as long as may reasonably be
required, by reason of accidents, strikes, the making of repairs, alterations or
improvements, lockouts, riots, acts of God, governmental preemption in
connection with a national or local emergency, inability to secure a proper
supply of fuel, steam, water, electricity, labor or supplies, laws, orders or
regulations of any governmental authority, Landlord's compliance with any
mandatory governmental energy conservation or environmental protection program
or any voluntary governmental energy conservation program, the request or
consent of Tenant, or by reason of any other cause beyond the reasonable control
of Landlord, subject to the following provisions of this Section 11.11. Landlord
shall not, however, except in an emergency (i) voluntarily effect any shutdown
or reduction of any service without at least ten (10) business days prior notice
to Tenant of the time and duration thereof, or (ii) voluntarily effect or
continue any shutdown or reduction of (x) electricity, domestic water or
condenser water other than during the hours of 8:00 a.m. Saturday through 8:00
p.m. on Sunday, or (y) any other service (excluding cleaning) during Business
Hours. Additionally, except in emergency, Tenant, by notice to Landlord given


                                       50

   62

within five (5) business days of its receipt of Landlord's notice pursuant to
clause (i) of the preceding sentence relative to any service shutdown or
reduction, may require Landlord to postpone such service shutdown or reduction
by thirty (30) days. In case of any service shutdown or reduction arising out
of, or the ending of which requires, any work by Landlord, Landlord shall
prosecute such work diligently and continuously so as to minimize the duration
of such service shutdown or reduction. All non-emergency service, repairs and
other work to Building elevators and escalators shall be done outside Business
Hours, except for any extended repairs or other work that requires more than a
single evening; such extended repairs or other work shall be confined to one (1)
elevator or escalator per bank at any time (and the other escalator shall be
configured to run up).

            11.12 Damage or Defective Condition. Tenant shall give to Landlord
prompt notice of any damage to, or defective condition in, any part or
appurtenance of the Building's sanitary, electrical, heating, air conditioning,
ventilation or other systems serving, located in, or passing through, the
Premises becoming known to Tenant's director of building operations (exclusive
of any such damage or defective condition to or in any fixtures, equipment,
improvements or installations installed by Tenant) and the damage or defective
condition shall be remedied by Landlord with reasonable diligence, provided,
however, that if the damage or defective condition was caused by, or by the
improper use of any of the systems by, Tenant or its employees, licensees or
invitees and is not coverable by an "all risk" insurance policy, the cost of the
remedy thereof shall be paid by Tenant within twenty (20) days of Landlord's
demand accompanied by appropriate supporting documentation. Tenant shall not be
entitled to claim any damages or offset in Fixed Rent or Additional Rent arising
from any such damage or defective condition, nor shall Tenant be entitled to
claim any eviction by reason of any such damage or defective condition.

            11.13 Building Directory. Landlord shall maintain touch-screen
directories of tenants of the Building in the Building atrium at the Maiden Lane
and Pine Street entrances and on the mezzanine level. Landlord shall, at the
request of Tenant, maintain listings on such directories of Tenant and any other
person, firm or corporation in occupancy of the Premises or any part thereof as
permitted hereunder, and the names of any officers or employees of the
foregoing; provided, however, that the number of names so listed shall be in the
same proportion to the capacity of the Building directory as the aggregate
number of rentable square feet of the Premises is to the aggregate number of
rentable square feet of the Building, but in no event less than one per 150
square feet of rentable area of the Premises. The listing of any name other than
that of Tenant, whether on the doors or windows of the Premises, on the Building
directory, or otherwise, shall not operate to vest any right or interest in this
Lease or in the Premises or be deemed to be the consent of Landlord mentioned in
Article 12 below, nor shall it be deemed to be the consent of Landlord to any
assignment or transfer of this Lease or to any sublease of the Premises or to
the use or occupancy thereof by others.

            11.14 Operation & Maintenance of the Building. Landlord shall
operate and maintain the Building and provide all services consistent with
standards for a Class A office



                                       51
   63

building in downtown Manhattan. Landlord shall maintain in condition befitting a
Class A office building in downtown Manhattan the Building's structure and
shell, all common, service and utility areas and facilities of the Building and
the Building's electrical, heating, ventilating, air-conditioning, plumbing,
sanitary, sprinkler, fire life safety and other systems (excluding any portions
thereof installed by Tenant) (all of the foregoing being herein called the "Base
Building"), and shall make all repairs and replacements to the Base Building
required to keep the same in such condition. Landlord shall clean and police the
Building atrium and shall clean, maintain, repair and replace all personal
property therein as befitting a Class A office building in downtown Manhattan,
including the plants and landscaping therein.

            11.15 Accessibility and Security (a) Landlord shall provide a
uniformed guard twenty-four (24) hour a day seven (7) days a week at the Maiden
Lane entrance to the Building for security purposes and to provide ADA
accessibility and assistance as needed.

            (b) The provisions of this Section 11.15(b) shall be applicable
during Business Hours.

                  Persons shall be permitted to enter the Building atrium at the
            Maiden Lane and Pine Street entrances and proceed to the mezzanine
            level without clearing security.

                  Landlord shall station security personnel at both the south
            security desk on the mezzanine level and the north security desk on
            the mezzanine level.

                  Persons displaying an identification card issued by Tenant (a
            "Tenant ID Card") shall be permitted to pass Landlord security at
            either the north or south security desk on the mezzanine level.

                  Persons without a Tenant ID Card seeking to enter the Premises
            shall be required to clear Landlord security on the mezzanine level
            and Landlord's security personnel will notify Tenant whenever any
            such person seeks access to the Premises and shall admit such person
            if Tenant authorizes such entry.

                  Notwithstanding the preceding paragraph (i) Tenant shall have
            the right to station its own security personnel at the south
            security desk on the mezzanine level (in addition to Landlord's
            security personnel at such desk) and (ii) so long as and whenever
            Tenant stations its own security personnel at the south security
            desk persons without a Tenant ID Card seeking to enter the Premises
            shall be processed by Tenant's security personnel rather than
            Landlord's security personnel. Tenant's security personnel may issue
            a day pass to any such person and, by displaying a current day pass
            issued by


                                       52
   64

            Landlord security at either the north or south security desk on the
            mezzanine level.

            (c) The provisions of this Section 11.15(c) shall be applicable
other than during Business Hours.

                  Persons shall be permitted to enter the Building atrium only
            at the Maiden Lane entrance and shall be subject to security at that
            location.

                  Landlord shall station security personnel at the Maiden Lane
            entrance.

                  Persons displaying a Tenant ID Card shall be permitted to pass
            Landlord security on the plaza level and proceed to the mezzanine
            level.

                  Persons without a Tenant Employee ID Card seeking to enter the
            Premises shall be required to clear security on the plaza level and
            Landlord's security personnel will notify Tenant whenever any such
            person seeks access to the Premises and shall admit such person if
            Tenant authorizes such entry.

                  Notwithstanding the preceding paragraph (i) Tenant shall have
            the right to install and station security personnel at its own
            security desk on the plaza level, near the Maiden Lane entrance, and
            (ii) so long as and whenever Tenant stations its own security
            personnel on the plaza level persons without a Tenant ID Card
            seeking to enter the Premises shall be processed by Tenant's
            security personnel rather than Landlord's security personnel.
            Tenant's security personnel may issue a day pass to any such person
            and, by displaying a current day pass issued by Tenant's security
            personnel, such person shall be permitted to pass Landlord security
            on the plaza level (and proceed to the mezzanine level).

                  Either party may provide additional security at the mezzanine
            level, but any person displaying a Tenant ID Card or a current day
            pass issued by Tenant's security personnel shall be permitted to
            pass any such additional Landlord security.

            (d) Tenant shall furnish Landlord with samples of its Tenant ID Card
and day pass. Landlord shall not be responsible for verifying that any person
displaying a Tenant ID Card or a day pass issued by Tenant is in fact the
authorized holder thereof. Persons displaying a Tenant ID Card or a day pass
issued by Tenant shall not be required by Landlord to sign any register upon
leaving or entering the Building at any time.

            (e) Tenant shall have the right to control access to the low-rise
elevator bank (and in the event Tenant shall ever lease all premises served by
the mid-rise elevator bank or the high-rise elevator bank, such additional
elevator bank or banks, as applicable). Tenant


                                       53
   65

shall have the right (i) for such purpose to install (A) turnstiles and gates to
the low-rise elevator bank (and in the event Tenant shall ever lease all
premises served by the mid-rise elevator bank or the high-rise elevator bank,
such additional elevator bank or banks, as applicable), and/or (B) to install
partitions to separate any elevator bank to which Tenant has the right to
control access from any elevator bank or other area to which Tenant does not
have the right to control such access, subject, in either case, to Landlord's
prior approval of the plans therefor, which approval shall not be unreasonably
withheld, or (ii) to exercise such control by other means, subject to the
approval of Landlord which approval shall not be unreasonably withheld.

            (f) Tenant shall have the right (i) to install computers and
telephones at its security desks and (ii) to run voice, data and/or electrical
conduits from the Premises or Tenant's Shafts to such computers and telephones
and to any equipment installed by Tenant to control access to any elevator bank.
Landlord shall furnish electricity to any such computers, telephones and
equipment.

            11.16 Tenant's Car Service Line. Landlord shall (at no cost to
Landlord) cooperate with Tenant's efforts to sign any permit applications
requested by Tenant to enable Tenant to acquire rights to use the area directly
in front of the Maiden Lane entrance for its car service line.

            11.17 Applicable Price. The term "Applicable Price" as used with
respect to each item referred to Exhibit O shall mean the price set forth
therefor on Exhibit O (the "Original Applicable Price"); provided, however, that
on January 1, 2000 and on each succeeding January 1, Landlord may adjust the
Applicable Price of each item to reflect increases in the actual cost to
Landlord of providing such item; provided, however, that in no event shall the
Applicable Price for any item any year exceed product of the Original Applicable
Price for such item multiplied by the CPI Factor for such year.

            The term "CPI Factor" shall mean for any year the quotient of the
Index for January of such year divided by the Index for January 1999. The term
"Index" shall mean the Revised Consumer Price Index for All Urban Consumers
(i.e., the "CPI-U") published by the Bureau of Labor Statistics of the United
States Department of Labor ("BLS"), for New York-Northern New Jersey-Long
Island, NY-NJ-CT, All Items (1982-84 = 100). IF BLS changes the publication
frequency of Index so that an Index is not available for the month of January to
make any adjustment specified herein, the adjustment in question shall be based
on the percentage difference between the Index for the closest preceding month
for which an Index is available and the Index for the corresponding month in
1999. If BLS changes the base reference period for the Index from 1982-84 = 100,
the adjustments required hereunder shall be determined with the use of such
conversion formula or table as may be published by BLS. If BLS otherwise
substantially revises, or ceases publication of, the Index, then a substitute
index for determining the adjustments required hereunder, issued by BLS or by a
reliable governmental or other nonpartisan publication, shall be reasonably
designated by Landlord.

            11.18 Fire Alarm. Tenant shall have the right to install a new
"state of the art" micro-processor based data gathering panel (DGP) on each
floor for incorporation into the existing base building fire alarm system. The
DGPs shall be microprocessor based, and include distributed amplification and
distributed power supplier. Tenant shall have the right to install a redundant
(second) Fire Alarm System riser cable, connected to the base building system,
to serve Tenant's DGPs. In connection with this work, Tenant may relocate the
existing building fire alarm system due to its location within the CNA Closet.
In performing its work under this Section Tenant shall comply with Applicable
Law, including applicable fire regulations, and shall purchase components from
the manufacturer of the base building system.

            Article 12. Assignment and Subletting.

            12.1 General. Except as hereinafter provided, Tenant, for itself,
its distributees, administrators, legal representatives, successors and assigns,
expressly covenants that it shall not, directly or indirectly, by operation of
law or otherwise, assign, mortgage or encumber this Lease or any part thereof,
or underlet, or suffer, or permit the Premises or any part thereof to be used or
occupied by others, without the prior written consent of Landlord in each
instance. If this Lease or any part thereof is assigned, or if the Premises or
any part thereof is underlet, used or occupied by anyone other than Tenant,
Landlord may, after default beyond any applicable notice or cure period by
Tenant, collect rent from the assignee, undertenant, user or occupant, and apply
the net amount collected to the rent herein reserved, but no assignment,
underletting, use, occupancy or collection shall be deemed a waiver (except to
the extent Landlord has collected Fixed Rent and Additional Rent) of the
provisions hereof, or the acceptance of the assignee, undertenant, user or
occupant as tenant, or a release of Tenant from the further performance by
Tenant of covenants on the part of Tenant herein contained. The consent by
Landlord to an assignment, mortgage, encumbrance, underletting, use or occupancy
shall not in any way be construed to relieve Tenant or any assignee or subtenant
from obtaining the express consent in writing of Landlord to any further
assignment, mortgage, encumbrance, underletting, use or occupancy to the extent
required by the terms of this Article. Each assignee and each subtenant shall be
bound by the same obligations and entitled to the same rights as Tenant under
this Article 12, including the rights provided by Sections 12.7 and 12.8 except
that (i) the proviso to Section 12.7 shall not be applicable to any subtenant,
and (ii) when applying Section 12.8 to any subtenant the term "Related Party"
shall be defined by reference to such subtenant rather than Tenant. Tenant shall
not include in any advertisement the proposed sublease rental rate.
Notwithstanding any subletting to any subtenant or acceptance of rent or
additional rent by Landlord from any subtenant, Tenant shall and will remain
fully liable for the payment of the Fixed Rent and Additional Rent due and to
become due hereunder and for the performance of a11 the covenants, agreements,
terms, provisions and conditions contained in this Lease on the part of Tenant
to be performed and all acts and omissions of any subtenant or anyone claiming
under or through any subtenant that shall be in violation of any of the
obligations of this Lease, and any violation shall be deemed to be a violation


                                       55
   67

by Tenant. Any amendment or modification to a sublease which shall extend the
term thereof or shall expand the premises demised thereby (other than, in either
case, pursuant to the exercise of an option or right set forth therein) shall,
as to such extension or expansion, be deemed to constitute a new sublease to
which the provisions of this Article 12 shall separately apply; any other
amendment or modification of a sublease shall not be deemed a new sublease but
Tenant shall furnish Landlord with a copy thereof prior to the effectiveness
thereof.

            12.2 Request for Consent. Each request by Tenant for Landlord's
consent to any assignment of this Lease or any sublease of all or any part of
the Premises shall be accompanied by

                  (i) a statement of the proposed effective or commencement date
            of the proposed assignment or sublease, which shall be not less than
            ten (10) business days nor more than one (1) year after the giving
            of the notice,

                  (ii) in the case of a proposed sublease, (x) a description of
            the premises proposed to be sublet, including all premises covered
            by any expansion rights and options proposed to be included in such
            proposed sublease (together, the "Proposed Sublease Premises"), and
            (y) a statement of the proposed expiration date of the proposed
            sublease, assuming the exercise of any renewal options proposed to
            be included in such proposed sublease (the "Proposed Sublease
            Expiration Date"),

                  (iii) a statement setting forth in reasonable detail the
            identity of the proposed assignee or subtenant and the nature of its
            business,

                  (iv) a confirmation that the proposed primary use of the
            premises to which such assignment or sublease shall relate is office
            use or if such proposed primary use is not office use, then a
            statement setting forth the proposed primary use of the Premises,

                  (v) if known to Tenant, a statement of the identity of any
            broker who may be entitled to a commission in respect of the
            proposed assignment or subletting,

                  (vi) such financial information with respect to the proposed
            assignee or subtenant, as shall have been furnished to Tenant by
            such assignee or subtenant (it being agreed, however, that in the
            case of a proposed sublease Landlord shall not be entitled to
            withhold its consent by reason of the financial condition of the
            proposed subtenant), and


                                       56
   68

                  (vii) in the case of a proposed assignment, such other
            information reasonably requested by Landlord within five (5) days of
            its receipt of the information referred to in the preceding clauses
            of this sentence.

            12.3 Consent Not to Be Unreasonably Withheld; Conditions. Provided
that Tenant is not in default of any of Tenant's obligations under this Lease
beyond any applicable notice or grace period, Landlord's consent to the proposed
assignment or sublease shall not be unreasonably withheld, provided that the
following conditions are satisfied:

                  (a) Tenant shall have complied with the provisions of Section
            12.2 of this Article;

                  (b) The proposed assignee or subtenant is engaged in a
            business that is in keeping with the standards of the Building;

                  (c) The proposed assignee or subtenant is a reputable entity
            of good character;

                  (d) The proposed assignee or sublessee is not an entity with
            whom Landlord is then negotiating to lease comparable space in the
            Building which Landlord has available for a comparable term; and

                  (e) In the case of a proposed sublease, there shall not be
            more than three (3) occupants (including Tenant) of each floor of
            the Premises on which all or any portion of the premises proposed to
            be subleased shall be located, provided that an entity, together
            with its Related Parties, shall be considered a single occupant for
            purposes of this Section 12.3(e).

            Within ten (10) business days after receipt by Landlord of all
information required by Section 12.3 Landlord shall either (i) grant consent in
the form attached hereto as Exhibit P or (ii) furnish Tenant with a notice that
it withholds consent and of its reasons therefor. If Landlord shall fail timely
to grant such consent or furnish such notice, Landlord shall be deemed to have
granted such consent.

            Tenant shall reimburse Landlord, within thirty (30) days of receipt
of an invoice from Landlord therefor, for any actual reasonable out-of-pocket
costs that may be incurred by Landlord to independent third parties in
connection with the considering Tenant's request for consent, including, without
limitation, the costs of making investigations as to the acceptability of the
proposed assignee or subtenant, and reasonable legal costs incurred in
connection with the granting of any requested consent.

            If Landlord shall decline to give its consent to any proposed
assignment or sublease, Tenant shall indemnify, defend and hold harmless the
Landlord Indemnitees against and from any and all Claims that may be made
against the Landlord Indemnitees by


                                       57
   69

the proposed assignee or sublessee or by any brokers or other persons claiming a
commission or similar compensation in connection with the proposed assignment or
sublease.

            12.4 Effect of Consent.

            Each consent to assignment issued by Landlord pursuant to Section
12.3 shall be effective with respect to any assignment of this Lease to the
assignee identified in Tenant's request for consent provided that such
assignment (i) is fully-executed and delivered (and a copy thereof delivered to
Landlord) within 270 days of Tenant's request for consent, and (ii) is effective
on a date no earlier than the date set forth in Tenant's request for consent. If
Tenant proposes to enter into any assignment of this Lease not conforming to the
foregoing provisions of this paragraph, Tenant shall again be required to comply
with the foregoing provisions of this Article 12.

            Each consent to sublease issued by Landlord pursuant to Section 12.3
shall be effective with respect to any sublease of all or any portion of the
Proposed Sublease Premises identified in Tenant's request for consent to the
subtenant identified in Tenant's request for consent provided that such sublease
(i) is fully-executed and delivered (and a copy thereof delivered to Landlord)
within 270 days of Tenant's request for consent, (ii) commences no earlier than
the proposed commencement date set forth in Tenant's request for consent, and
(iii) expires (assuming the exercise of any renewal options provided for
therein) no later than the Proposed Sublease Expiration Date set forth in
Tenant's request for consent. If Tenant proposed to enter into any sublease of
all or any portion of the Premises not conforming to the foregoing provisions of
this paragraph, Tenant shall again be required to comply with the foregoing
provisions of this Article 12.

            Tenant shall deliver to Landlord prior to the effective date of the
assignment or the commencement date of the sublease executed copies of such
assignment or sublease as well as all other agreements, if any, relating to such
assignment or sublease, and, if not fully disclosed thereby, a statement of all
consideration to be received by Tenant for or in connection with the assignment
or sublease and the terms of payment therefor.

            12.5 Provisions Applicable to Every Sublease. With respect to each
and every sublease or subletting authorized by Landlord under the provisions of
this Lease or for which Landlord's consent is not required, it is further agreed
that:

                  (a) No subletting shall be for a term ending later than one
            (1) day prior to the Expiration Date of this Lease;

                  (b) No sublease shall be valid, and no subtenant shall take
            possession of the Premises or any part thereof, until an executed
            counterpart of the sublease has been delivered to Landlord; and


                                       58
   70

            (c) Each sublease shall provide that it is subject (to the extent
      applicable to the subleased premises and sublease term) and subordinate to
      this Lease and to the matters to which this Lease is or shall be
      subordinate, and that in the event of termination, re-entry or dispossess
      by Landlord under this Lease Landlord may, at its option, take over all of
      the right, title and interest of Tenant, as sublessor, under the sublease,
      and the subtenant shall, at Landlord's option, attorn to Landlord pursuant
      to the executory provisions of the sublease, except that Landlord shall
      not (1) be liable for any previous act or omission of Tenant under the
      sublease, (2) be subject to any offset, not expressly provided in the
      sublease, that theretofore accrued to the subtenant against Tenant, or (3)
      be bound by any modification of the sublease made after Landlord's so
      taking over such right, title and interest unless Landlord has consented
      to such modification or by any previous prepayment of more than one
      month's rent.

            12.6 Profit-Sharing. If Landlord shall give its consent to any
assignment of this Lease or to any sublease, Tenant shall in consideration
therefor, pay to Landlord, as additional rent:

            (a) in the case of an assignment, an amount equal to fifty percent
      (50%) of all sums (excluding rent payable under this Lease, which shall be
      payable directly to Landlord) and other consideration payable to Tenant by
      the assignee for or by reason of the assignment (including, but not
      limited to, sums paid for the sale or rental of Tenant's fixtures,
      leasehold improvements, equipment, furniture, furnishings or other
      personal property, less the net unamortized cost thereof determined on the
      basis of generally accepted accounting principles consistently applied)
      reduced (but not below zero) by (i) the actual expenses incurred in good
      faith by Tenant in connection with such assignment including without
      limitation, e.g., lease takeover payments and other tenant allowances,
      reasonable attorney's fees, cost of initial alterations made to the
      Premises (or portions thereof) for the benefit of the assignee and
      brokerage and leasing commissions, and (ii) an amount equal to the Fixed
      Rent and Additional Rent payable under this Lease during the period
      commencing on the date the Premises was vacated by Tenant through the
      effective date of the assignment, but in no event to exceed six (6)
      months, payable if, as and when Tenant receives such sums, after
      recoupment by Tenant of such actual expenses referred to in clause (i)
      above and such amount referred to in clause (ii) above; and

            (b) in the case of a sublease, fifty percent (50%) of any rents,
      additional charges or other considerations payable under the sublease to
      Tenant by the subtenant that are in excess of the Fixed Rent and
      Additional Rent accruing during the term of the sublease in respect of the
      subleased space (at the rate per square foot payable by Tenant hereunder)
      pursuant to the terms hereof (including, but not limited to, sums paid for
      the sale or rental of Tenant's fixtures, leasehold improvements,
      equipment, furniture, furnishings or other personal property, less the net
      unamortized cost thereof determined on the basis of generally accepted
      accounting principles consistently


                                       59
   71

      applied) reduced (but not below zero) by (i) the actual expenses incurred
      in good faith by Tenant in connection with such sublease including,
      without limitation, e.g., lease takeover payments and other tenant
      allowances, reasonable attorney's fees, cost of initial alterations made
      to the subleased space for the benefit of the sublessee and brokerage and
      leasing commissions and (ii) an amount equal to Fixed Rent and Additional
      Rent payable under this Lease in respect of the subleased space for the
      period commencing on the date the subleased space was vacated by Tenant
      through the commencement date of the sublease, but in no event to exceed
      six (6) months, payable if, as and when Tenant receives such sums, after
      recoupment by Tenant of such actual expenses referred to in clause (i)
      above and such amount referred to in clause (ii) above.

            12.7 Changes in Control; Transactions with Successors. Sections
12.1, 12.2, 12.3, 12.4 and 12.6 of this Article shall apply to a transfer,
directly or indirectly, by one or more transfers (other than transfers of
publicly traded interests in Tenant), of a majority of the beneficial interest
of Tenant only if the primary purpose thereof is the circumvention of the
conditions and restrictions set forth in this Article 12, as if such transfer
were an assignment of this Lease. The first sentence of Section 12.1 and
Sections 12.2, 12.3, 12.4, 12.5 and 12.6 of this Article shall not apply to, and
Landlord's consent shall not be required for, transactions with a corporation or
other entity into or with which Tenant is merged or consolidated or to which all
or substantially all of Tenant's assets are transferred; provided that in either
case (1) the successor to Tenant has a net worth computed in accordance with
generally accepted accounting principles of not less than the product of
eighteen (18) multiplied by the per annum Fixed Rent then payable under this
Lease, and (2) proof reasonably satisfactory to Landlord of such net worth shall
have been delivered to Landlord no later than ten (10) days after the effective
date of the transaction.

            12.8 Transactions with Related Parties. The first sentence of
Section 12.1 and Sections 12.2, 12.3, 12.4, 12.5 and 12.6 of this Article shall
not apply to, and Landlord's consent shall not be required for, any assignment
or sublease by Tenant to any Related Party or to the occupancy of any portion of
the Premises by a Related Party without a subletting or assignment. For the
purposes of this Section, a "Related Party" shall mean (x) any corporation,
partnership or other entity which, at the time of the making of such assignment
or sublease or the commencement of such occupancy, is controlled by, controls,
or is under common control with, Tenant, (y) any service provider of Tenant
(such as, for example, any consultant providing services (e.g., travel,
technology, legal or accounting services) to Tenant and/or its employees, but
not to the public) and (z) any entity that acquires one of Tenant's business
units or divisions.

            12.9 Miscellaneous Provisions Regarding Assignments. Any assignment
of this Lease (other than an assignment by operation of law in connection with a
merger or consolidation), whether made with Landlord's consent pursuant to
Section 12.1 of this Article, or without Landlord's consent pursuant to Section
12.7 or 12.8 of this Article, shall be made only if, and shall not be effective
until, the assignee shall execute, acknowledge and


                                       60
   72

deliver to Landlord an agreement in the form attached hereto as Exhibit Q. No
such assignment shall release any predecessor tenants, including the
original-named Tenant, from liability. The joint and several liability of Tenant
and any assignee or immediate or remote successor in interest of Tenant and the
due performance of the obligations of this Lease on Tenant's part to be
performed or observed shall not be discharged, released or impaired in any
respect by any agreement or stipulation made by Landlord extending the time of,
or modifying any of the obligations of, this Lease, or by any waiver or failure
of Landlord to enforce any of the obligations of this Lease.

            Article 13. Damage by Fire, etc.

            13.1 If any part of the Premises shall be damaged by fire or other
casualty, Tenant shall give prompt notice thereof to Landlord. If any part of
the Premises or of the Base Building shall be damaged by fire or other casualty
Landlord shall, subject to the provisions of Section 13.2, proceed with
reasonable diligence to repair the damage, and if any part of the Premises shall
be rendered untenantable by reason of such damage to the Premises or the Base
Building, the annual Fixed Rent and the Additional Rent on account of Real
Estate Taxes, Operating Costs and Cleaning Costs payable hereunder, to the
extent that the Fixed Rent and the Additional Rent on account of Real Estate
Taxes, Operating Costs and Cleaning Costs relates to the part of the Premises
that has been rendered untenantable, shall be abated for the period from the
date of the damage to the date when such part of the Premises shall have been
made tenantable or to any earlier date upon which the term of this Lease shall
expire or terminate. As used in this Article, the term "untenantable" shall
mean, with respect to the Premises or any portion thereof, that the same is
unsuitable for use (and is not used) in the normal manner for the purpose for
which leased, by reason of damage or destruction therein or to the Base
Building, or by reason of interruption or diminution in any of the services
otherwise ordinarily provided thereto, or by reason of not being reasonably
accessible. In the event a rent abatement occurs under this Article with respect
to a portion of the Premises then subject to another abatement of rent under
this Lease, the other abatement period shall be extended with respect to such
portion of the Premises one (1) day for each day of the abatement period under
this Article. Landlord shall not be liable for any inconvenience or annoyance to
Tenant or injury to the business of Tenant resulting in any way from any damage
or the repair thereof. Tenant acknowledges that Landlord is not obligated to
carry insurance of any kind on Tenant's goods, furniture or furnishings or on
any fixtures, equipment, improvements, installations or appurtenances installed
by Tenant or removable by Tenant as provided in this Lease, and that Landlord
shall not be obligated to repair any damage thereto or replace the same.

            13.2 If repair or restoration of the Building (excluding goods,
furniture or furnishings and any fixtures, equipment, improvements,
installations or appurtenances installed by or for any tenant or removable by
any tenant) reasonably estimated to cost at least fifty percent (50%) of the
full insurable value of the Building (excluding goods, furniture or furnishing
and any fixtures, equipment, improvements, installations or appurtenances
installed by or for any tenant or removable by any tenant) shall be required


                                       61
   73

as a result of damage by fire or other casualty (whether or not the Premises
shall have been damaged by fire or other casualty), then this Lease and the term
and estate hereby granted may be terminated by Landlord by its giving to Tenant
within ninety (90) days after the date of the damage a notice specifying a date,
not less than thirty (30) days after the giving of the notice, for the
termination; provided, however, that, at Tenant's election, no such notice of
termination shall be effective unless Landlord shall also simultaneously
terminate all other leases of space in the Building. In the event of the giving
of notice of termination, this Lease and the term and estate hereby granted
shall expire as of the date specified therefor in the notice, with the same
effect as if that date were the Expiration Date, and the Fixed Rent and
Additional Rent payable hereunder shall be apportioned as of the date of
termination, subject to abatement, if any, as and to the extent above provided.

            13.3 If because of damage by fire or other casualty more than
twenty-five percent (25%) of the floor area of the Premises shall have been
rendered untenantable, Landlord shall deliver to Tenant within forty-five (45)
days of the date of the fire or other casualty the determination of an
independent architect or engineer selected by Landlord, subject to Tenant's
approval (not to be unreasonably withheld), of the estimated time to complete
the repair and restoration required by Section 13.1 (the "Estimated Repair
Time"). If such independent architect's or engineer's determination of the
Estimated Repair Time is greater than one hundred eighty (180) days from the
date of the fire or other casualty, Tenant may terminate this Lease by giving
notice of termination to Landlord within thirty (30) days after the receipt by
Tenant of notice from Landlord specifying such independent architect's or
engineer's determination of the Estimated Repair Time. If Tenant does not
terminate this Lease as provided above or such independent architect's or
engineer's determination of the Estimated Repair Time was less than one hundred
eighty (180) days, and Landlord fails to complete the repair and restoration
required by Section 13.1 within the Estimated Repair Time plus thirty (30) days,
Tenant may terminate this Lease by giving notice of termination to Landlord
within thirty (30) days after the expiration of the Estimated Repair Time plus
thirty (30) days. If Tenant gives notice to Landlord to terminate this Lease as
provided above, this Lease shall terminate on the date provided for in the
notice by Tenant, but in no event later than twelve (12) months after the giving
of the notice, with the same effect as if the date specified in the notice was
the Expiration Date and the Fixed Rent and Additional Rent payable hereunder
shall be apportioned as of the date of termination, subject to abatement, if
any, as and to the extent above provided.

            13.4 Nothing herein contained shall relieve Tenant from any
liability to Landlord in connection with any damage to the Premises or the
Building or Landlord's property therein by fire or other casualty if Tenant
shall be legally liable therefor, except, however, that Landlord hereby releases
Tenant with respect to any liability that Tenant might otherwise have had to
Landlord for any damage to the Premises or the Building or Landlord's property
therein by fire 6r other casualty occurring during the term of this Lease to the
extent arising from a casualty or other event coverable by an "all risk"
insurance policy.

   74

            13.5 This Lease shall be considered an express agreement governing
any case of damage to or destruction of, or any part of, the Building or the
Premises by fire or other casualty, and Section 227 of the Real Property Law of
the State of New York providing for a contingency in the absence of express
agreement, and any other law of like import now or hereafter in force, shall
have no application hereunder.

            Article 14. Condemnation.

            14.1 In the event that the whole of the Premises shall be lawfully
condemned or taken in any manner for any public or quasi-public use, this Lease
and the term and estate hereby granted shall forthwith cease and terminate as of
the date of vesting of title as a result of the condemnation or taking.

            14.2 In the event that only a part of the Premises shall be
condemned or taken, then the term and estate hereby granted with respect to that
part of the Premises shall forthwith cease and terminate as of the date of
vesting of title as a result of the condemnation or taking and the Fixed Rent
and the Additional Rent on account of Real Estate Taxes, Operating Costs and
Cleaning Costs payable hereunder, to the extent that the Fixed Rent and the
Additional Rent on account of Real Estate Taxes, Operating Costs and Cleaning
Costs relate to that part of the Premises, shall be abated for the period from
the date of the vesting of title to the Expiration Date with respect to that
part of the Premises. In the event a rent abatement occurs under this Article
with respect to a portion of the Premises then subject to another abatement of
rent under this Lease, the other abatement period shall be extended with respect
to such portion of the Premises one (1) day for each day of the abatement period
under this Article.

            14.3 In the event that only a part of the Building shall be
condemned or taken, then (i) if more than twenty-five percent (25%) of the floor
area of the Building has been condemned or taken (whether or not the Premises
are affected), this Lease and the term and estate hereby granted may be
terminated by Landlord by giving to Tenant, within sixty (60) days following the
date on which Landlord shall have received notice of the vesting of title,
written notice specifying a date, not less than thirty (30) days after the
giving by Landlord of the notice, for the termination, and (ii) if the
condemnation or taking shall be of a substantial part of the Premises or of a
substantial part of the means of access thereto, this Lease and the term and
estate hereby granted may be terminated by Tenant by giving to Landlord, within
sixty (60) days following the date upon which Tenant shall have received notice
of the vesting of title, written notice specifying a date, not less than thirty
(30) days after the giving by Tenant of the notice, for the termination, or
(iii) if neither Landlord nor Tenant elects to terminate this Lease as
aforesaid, this Lease shall be and remain unaffected by the condemnation or
taking, except that this Lease and the term and estate hereby granted with
respect to the part of the Premises so condemned or taken shall expire on the
date of the vesting of title to that part and except that the Fixed Rent and the
Additional Rent payable with respect to Real Estate Taxes, Operating Costs and
Cleaning Costs payable hereunder shall be abated to the extent, if any,
hereinabove provided in this Article. In the event that


                                       63
   75

only a part of the Premises shall be condemned or taken and this Lease and the
term and estate hereby granted with respect to the remaining portion of the
Premises are not terminated as hereinabove provided, landlord will proceed with
reasonable diligence to restore the remaining portion of the Premises as nearly
as practicable to the same condition it was in prior to the condemnation or
taking.

            14.4 The termination of this Lease and the term and estate hereby
granted in any of the cases hereinabove provided shall be with the same effect
as if the date of the termination were the Expiration Date, and the Fixed Rent
and Additional Rent payable hereunder shall be apportioned as of the date of
termination.

            14.5 In the event of any condemnation or taking hereinabove
mentioned of all or a part of the Building, Landlord shall be entitled to
receive the entire award in the condemnation proceeding, including, without
limitation, any award made for the value of the estate vested by this Lease in
Tenant, and Tenant hereby expressly assigns to Landlord any and all right, title
and interest of Tenant now or hereafter arising in or to any award or any part
thereof, and Tenant shall be entitled to receive no part of any award; provided,
however, that nothing herein contained shall be deemed to preclude Tenant from
intervening for Tenant's own interest in any condemnation proceeding to claim or
receive from the condemning authority any compensation to which Tenant may
otherwise lawfully be entitled in respect of property owned by Tenant and
removable by it under Article 9 hereof.

            14.6 The provisions of this Article shall not be applicable to any
condemnation or taking for governmental occupancy for a limited period.

            Article 15. Compliance with Laws.

            15.1 Tenant shall comply with all laws, including without limitation
the Americans with Disabilities Act, and ordinances and all rules, orders,
regulations and requirements of all governmental authorities (collectively,
"Applicable Laws") at any time duly issued and in force requiring compliance in,
to or upon the Premises or any part thereof except that Tenant shall not be
under any obligation to comply with any Applicable Law requiring any structural
Alteration of or to the Premises unless the requirement for compliance arises
out of either (i) a condition that has been created by, or at the instance of,
Tenant, or (ii) a breach of any covenant, agreement, term, provision or
condition hereof on the part of Tenant to be kept, observed or performed.

            Landlord shall comply with all Applicable Laws at any time duly
issued and in force (a) requiring compliance in, to or upon the Base Building,
or (b) requiring any structural Alterations of or to the Premises which, by
reason of the exception set forth therein, Tenant is not required by the
preceding paragraph to make.

            The provisions of this Section 15.1 shall be applicable to any
requirement for compliance arising out of or being a condition to any
Alterations in or to or use of the


                                       64
   76

Premises made or proposed to be made by Tenant, except that if any such
compliance is required in, to or upon the Base Building by reason of Tenant's
using or proposing to use any portion of the Premises for any use not permitted
by the now-existing Certificate of Occupancy for the Building, Tenant shall be
required to effect such compliance; provided, however, that this sentence shall
not be applicable to any circumstance governed by the last paragraph of Section
5.1.

            15.2 Landlord represents to Tenant that the Building was built after
the use of asbestos was outlawed. A copy of the most current filed ACP-5 Form
for the Building shall be delivered by Landlord to Tenant prior to the Term
Commencement Date. In the event Tenant discovers any asbestos or any other
hazardous material (as hereinafter defined) in the Premises or in other portion
of the Building in which Tenant is permitted to install property or perform work
or in the common or service areas of the Building, Tenant shall have the right,
upon ten (10) business days prior written notice to Landlord, to remove such
asbestos or other hazardous material and (unless such asbestos or hazardous
material was placed or installed in the Premises or such portion of the Building
by Tenant) Landlord shall within twenty (20) days of demand therefor,
accompanied by appropriate documentation, repay to Tenant the actual cost of
removal incurred by Tenant. The term "hazardous material" as used herein shall
mean any petroleum or petroleum products (including oil, crude oil, natural or
synthetic gas) except as used in accordance with Applicable Law in connection
with fuel tanks and generators installed in the Building by Landlord or Tenant,
radioactive materials, any asbestos or asbestos containing materials, PCBs, any
explosive or flammable materials, or any other hazardous or toxic waste,
material or substance, including, without limitation, any waster, material or
substance now or hereafter included in the definition of "hazardous substances,"
"hazardous waste," "hazardous materials," "toxic substances," "toxic waste" or
"toxic material" or similar term contain in any law or governmental regulation.

          Article 16. Mortgage, Subordination, and Attornment.

            16.1 This Lease and the term and estate hereby granted are and shall
be subject and subordinate to the lien of each mortgage that may now or at any
time hereafter affect the Building, the Land, or Landlord's interest therein and
to all renewals, modifications, consolidations, replacements and extensions
thereof (each, an "Underlying Mortgage") and any underlying lease that may now
or at any time hereafter affect the Land or Building and to all renewals,
modifications, consolidations, replacements and extensions thereof (each, an
"Underlying Lease"). The foregoing provision for the subordination of this Lease
and the term and estate hereby granted shall be self-operative and no further
instrument shall be required to effect the subordination. Nevertheless, Tenant
shall, upon request by Landlord, at any time or times, execute and deliver any
and all instruments that may be necessary or proper to effect, confirm or
evidence the subordination.

            16.2 If Landlord's interest in the Building or the Land shall be
sold or conveyed to any person, firm or corporation upon the exercise of any
remedy provided for


                                       65
   77

in any Underlying Mortgage or by law or equity, the person, firm or corporation
and each person, firm or corporation thereafter succeeding to its interest in
the Building or the Land shall not be

                        (A) liable to pay damages to Tenant caused by any
            breach, act, omission or negligence of any prior landlord (including
            the then defaulting landlord), but (except for the holder of any
            Existing Mortgage) shall nonetheless remain subject to any and all
            abatements, deductions, offsets, claims, counterclaims and/or
            defenses which shall have accrued to Tenant against any prior
            landlord (including the then defaulting landlord) prior to the date
            that such person, firm or corporation shall have succeeded to the
            rights of the landlord under the Lease, but in any case, provided,
            however, such non-liability for damages shall neither diminish such
            person, firm or corporation's liability for continuing obligations
            of the landlord under the Lease nor diminish Tenant's right under
            the Lease with respect to the continuing failure of such person,
            firm or corporation to perform the obligations of the landlord under
            the Lease after the date that such person, firm or corporation
            succeeds to the interest of the landlord under the Lease;

                        (B) bound by any rent, additional rent or other items of
            rental under the Lease which Tenant might have paid for more than
            the current month to any prior Landlord (including the then
            defaulting Landlord); or

                        (C) bound by the terms of any agreement amending,
            modifying, supplementing or terminating the Lease (except as
            contemplated by this Lease) made without the written consent of the
            holder of such Underlying Mortgage, unless such consent shall have
            been unreasonably withheld.

            16.3 Notwithstanding the provisions of Section 16.1,

                  (i) the subordination of this Lease to (x) the Modified,
            Amended and Restated Mortgage, Spreader and Consolidation Agreement,
            dated as of January 9, 1989 and recorded on March 22, 1990 in Reel
            1677 page 2057 in the Office of the Register of New York County (the
            "Register's Office") in favor of the State of California - Public
            Employees Retirement System and State of California - State
            Teacher's Retirement System as in effect on the date hereof (the
            "Existing First Mortgage") and (y) the Modified, Amended and
            Restated Mortgage, Spreader and Consolidation Agreement, dated as of
            January 9, 1989 and recorded on March 22, 1990 in Reel 1678 page
            1918 in the Register's Office, as the same has been assigned, in
            favor of First Bank National Association, (successor to the Trustees
            of General Electric Pension Trust) as in effect on the date hereof
            (the "Existing Second Mortgage" and,


                                       66
   78

            together with the Existing First Mortgage, the "Existing Mortgages")
            shall be upon the terms and conditions set forth in Section 3.06 of
            each of the Existing Mortgages and

                  (ii) the subordination of this Lease (x) to any Underlying
            Mortgage other than the Existing Mortgages, (y) to any renewal,
            modification, consolidation, replacement or extension of any of the
            Existing Mortgages, or (z) to any Underlying Lease shall be subject
            to the delivery to Tenant by the mortgagee or lessor, as the case
            may be, of a non-disturbance agreement on the form attached hereto
            as Exhibit R in any case referred to in clause (x) or (y) above or
            an equivalent form in any case referred to in clause (z) above or,
            in either case, another form no less favorable to Tenant in any
            material respect.

Landlord represents that (a) there are currently no Underlying Mortgages other
than the Existing Mortgages and no Underlying Leases, and (b) Landlord has
repaid the principal of and all interest and prepayment charges on the Existing
First Mortgage (other than any amounts payable under Section 3.05 of the
Existing First Mortgage and Landlord believes that no such amounts are payable).

            16.4 Landlord shall, within five (5) days after the full execution
and delivery of this Lease by each party, deliver by certified mail, return
receipt requested, to the mortgagee under each of the Existing Mortgages the
certificate required pursuant to the terms of Section 3.06(b) of each of the
Existing Mortgages, and copies thereof shall be simultaneously delivered to
Tenant. Copies of the signed return receipts from the delivery of the
certificates and all responses received by Landlord from the mortgagees under
the Existing Mortgages shall be immediately delivered to Tenant. If the
mortgagee under either of the Existing Mortgages shall timely reject such
certificate Landlord shall so notify Tenant and Tenant shall have the right, by
notice to Landlord given within thirty (30) days of its receipt of such notice
from Landlord, to terminate this Lease.

            Article 17. Conditions of Limitation.

            17.1 This Lease and the term and estate hereby granted are subject
to the limitation that:

            (a) if Tenant shall default in the payment of any Fixed Rent or
      Additional Rent on any date upon which the Fixed Rent or Additional Rent
      becomes due and such default shall continue for ten (10) days after
      Landlord shall have given to Tenant a notice specifying the default,
      provided that Landlord shall not be required to give such notice with
      respect to a default in payment of Fixed Rent more than two (2) times in
      any twelve (12) month period;


                                       67
   79

            (b) if Tenant shall default in the due keeping, observance or
      performance of any covenant, agreement, term, provision or condition of
      this Lease (other than a default of the character referred to in Section
      17.1(a)), and if the default shall continue and shall not be remedied by
      Tenant within thirty (30) days after Landlord shall have given to Tenant a
      notice specifying the default, or, in the case of a default which cannot
      with due diligence be cured within the thirty (30) day period, if Tenant
      (i) shall not promptly upon the giving of the notice of default give
      Landlord notice of Tenant's intention to institute all steps necessary to
      remedy the default, (ii) shall not duly institute and thereafter
      diligently prosecute to completion all steps necessary to remedy the
      default, and (iii) shall not remedy the default within a reasonable time
      after the date of the giving of the notice by Landlord; or

            (c) in case any event shall occur or any contingency shall arise
      whereby this Lease or the estate hereby granted or the unexpired balance
      of the term hereof would, by operation of law or otherwise, devolve upon
      or pass to any person, firm or corporation other than Tenant, except as
      permitted under Article 12 hereof,

then in the event that (a), (b) or (c) occurs, Landlord may give to Tenant a
notice of intention to end the term of this Lease at the expiration of three (3)
days from the date of the giving of the notice, and, in the event the notice is
given, this Lease and the term and estate hereby granted (whether or not the
term shall theretofore have commenced) shall terminate upon the expiration of
the three (3) days with the same effect as if the last of the three (3) days
were the Expiration Date, and Tenant shall remain liable for damages as provided
in this Lease or pursuant to law.

            17.2 In addition, this Lease and the term and estate hereby granted
are subject to the limitation that whenever (a) Tenant, or any guarantor of
Tenant's obligations under this Lease (the "Guarantor"), shall commence any
case, proceeding or other action (1) under any existing or future law of any
jurisdiction, domestic or foreign, relating to bankruptcy, insolvency,
reorganization or relief of debtors, seeking to have an order for relief entered
with respect to it, or seeking to adjudicate it a bankrupt or insolvent, or
seeking reorganization, arrangement, adjustment, winding-up, liquidation,
dissolution, composition or other relief with respect to it or its debts; or (2)
seeking appointment of a receiver, trustee, custodian or other similar official
for it or for all or any substantial part of its assets, or Tenant or the
Guarantor shall make a general assignment for the benefit of its creditors; or
(b) there shall be commenced against Tenant or the Guarantor any case,
proceeding or other action of a nature referred to in clause (a) above that (1)
results in the entry of an order for relief or any adjudication or appointment
or (2) remains undismissed, undischarged or unbonded for a period of sixty (60)
days; or (c) Tenant or the Guarantor shall take any action in furtherance of, or
indicating its consent to, approval of, or acquiescence in, any of the acts set
forth in clauses (a) and (b) above; or (d) Tenant or the Guarantor shall
generally not, or shall be unable to, or shall admit in writing its inability
to, pay its debts as they become due; then Landlord may give Tenant a notice of
intention to end the term of this Lease at the expiration often (10) days from
the date of service of the notice of intention, and upon the


                                       68
   80

expiration of the ten (10) day period this Lease and the term and estate hereby
granted, whether or not the term shall theretofore have commenced, shall
terminate with the same effect as if that day were the Expiration Date, but
Tenant shall remain liable for damages as provided in this Lease or pursuant to
law.

            Article 18. Re-entry by Landlord.

            18.1 If this Lease shall terminate as provided in Article 17 hereof,
Landlord or Landlord's agents and servants may immediately or at any time
thereafter re-enter the Premises, or any part thereof, either by summary
dispossess proceedings or by any suitable action or proceeding at law, without
being liable to indictment, prosecution or damages therefor, and may repossess
the Premises or any part thereof, and may remove any persons therefrom, to the
end that Landlord may have, hold and enjoy the Premises again as and of its
first estate and interest therein. The words "re-enter", "re-entry" and
"re-entering" as used in this Lease are not restricted to their technical legal
meanings.

            18.2 In the event of any termination of this Lease under the
provisions of Article 17 hereof or in the event of the termination of this Lease
by or under any summary dispossess or other proceeding or action or other
measure undertaken by Landlord for the enforcement of its right of re-entry
(herein called a "Default Termination"), Tenant shall thereupon pay to Landlord
the Fixed Rent and Additional Rent up to the time of the Default Termination and
shall pay to Landlord any and all damages that, by reason of the Default
Termination, shall be payable by Tenant under this Lease or pursuant to law. In
the event of a Default Termination, Landlord also shall be entitled to retain
all money, if any, paid by Tenant to Landlord, whether as advance rent or as
security for rent, but the money shall be credited by Landlord against any Fixed
Rent and Additional Rent due from Tenant at the time of the Default Termination
or, at Landlord's option, against any damages payable by Tenant under this Lease
or pursuant to law.

            18.3 Tenant, for Tenant, and on behalf of any and all persons, firms
and corporations claiming through or under Tenant, including creditors of all
kinds, does hereby waive and surrender all right and privilege that they or any
of them might have under or by reason of any present or future law to redeem the
Premises or to have a continuance of this Lease for the term hereby demised
after Tenant is dispossessed or ejected therefrom by process of law or under the
terms of this Lease or after the expiration or termination of this Lease as
provided herein or pursuant to law. Tenant also waives (a) the right of Tenant
to trial by jury in any summary dispossess or other proceeding that may
hereafter be instituted by Landlord against Tenant in respect of the Premises or
in any action that may be brought to recover rent, damages or other sums payable
hereunder, and (b) the provisions of any law relating to notice or delay in levy
of execution in case of an eviction or dispossess of a tenant for nonpayment of
rent, and of any other law of like import, now or hereafter in effect. If
Landlord commences any summary dispossess proceeding, Tenant will not interpose
any counterclaim of any nature or description in the proceeding unless Tenant
would by its failure to interpose such counterclaim lose the right to assert
such counterclaim. Landlord


                                       69
   81

waives the right of Landlord to trial by jury in any action or proceeding
arising under this Lease.

            Article 19. Damages.

            19.1 In the event of a Default Termination of this Lease, Tenant
shall pay to Landlord as damages, at the election of Landlord, either:

            (a) a sum that, at the time of the Default Termination, represents
      the value of the excess, if any, of (i) the present value (using a
      discount rate equal to the then current prime rate established by
      Citibank, N.A. (the "Prime Rate")) of the aggregate of the Fixed Rent and
      the Additional Rent that, had this Lease not terminated, would have been
      payable by Tenant for the period commencing with the day following the
      date of the Default Termination and ending with the Expiration Date over
      (ii) the present value (using a discount rate equal to the then current
      Prime Rate) of the aggregate fair market rent of the Premises for the same
      period, or

            (b) sums equal to the aggregate of the Fixed Rent and the Additional
      Rent that would have been payable by Tenant had this Lease not terminated,
      payable upon the due dates therefor specified herein following the date of
      the Default Termination and ending with the Expiration Date; provided,
      however, that if Landlord shall re-let the Premises during said period,
      although Landlord shall have no obligation to do so, Landlord shall credit
      Tenant with the net rents received by Landlord from such re-letting, such
      net rents to be determined by first deducting from the gross rents as and
      when received by Landlord from such re-letting the reasonable expenses
      incurred or paid by Landlord in terminating this Lease or of re-entering
      the Premises and of securing possession thereof, including, without
      limitation, reasonable attorneys' fees and costs of removal and storage of
      Tenant's property, as well as the reasonable expenses of re-letting,
      including repairing, restoring, altering, decorating and preparing the
      Premises for new tenants, "buy-out" costs paid by on account of a new
      tenant's existing rent in other premises, brokers' commissions,
      advertising costs, and all other similar or dissimilar reasonable expenses
      chargeable against the Premises and the rental therefrom in connection
      with such re-letting, it being understood that any such re-letting may be
      for a period equal to or shorter or longer than the remaining term of this
      Lease; provided, further, that (i) in no event shall Tenant be entitled to
      receive any excess of such net rents over the sums payable by Tenant to
      Landlord hereunder, (ii) in no event shall Tenant be entitled in any suit
      for the collection of damages pursuant to this Section 19.1(b) to a credit
      in respect of any net rents from a re-letting except to the extent such
      net rents are actually received by Landlord, and (iii) if the Premises or
      part thereof should be re-let in combination with other space, then proper
      apportionment on a square foot area basis shall be made of the rent
      received from such re-letting and of the expenses of re-letting.

            19.2 Suit or suits for the recovery of any damages payable hereunder
by Tenant, or any installments thereof, may be brought by Landlord from time to
time at its election, and nothing contained herein shall be deemed to require
Landlord to postpone suit until the date when the term of this Lease would have
expired but for a Default Termination. Nothing herein shall be construed as
limiting or precluding the recovery by Landlord against Tenant of any sums or
damages to which, in addition to the damages particularly provided above,
Landlord may lawfully be entitled by reason of any default hereunder on the part
of Tenant.

            Article 20. Curing Tenant's Defaults - Additional Rent.

            20.1 If Tenant shall default in the keeping, observance or
performance of any covenant, agreement, term, provision or condition herein
contained, Landlord, without thereby waiving the default, may perform the same
for the account and at the expense of Tenant

                  (a) immediately or at any time thereafter and without prior
            notice (but with notice promptly after commencing such performance)
            in the case of emergency or in case the default unreasonably
            interferes with the use of the Building by any other tenant of any
            space in the Building or with the efficient operation of the
            Building or will result in a violation of law or cancellation of an
            insurance policy maintained by Landlord,

                  (b) without further notice or lapse of time, in case of any
            failure to procure and place any insurance required by this Lease
            which has continued after the giving of notice and lapse of time
            referred to in Section 22.5, and

                  (c) in any other case if the default continues after fifteen
            (15) days from the date of the giving by Landlord to Tenant of
            notice of Landlord's intention to perform the same; provided,
            however, that in any case under this clause (c) relative to a
            default the curing of which requires in excess of fifteen (15) days,
            if within such fifteen (15) days Tenant shall commence such cure and
            notify Landlord that it intends to prosecute the same to completion,
            such fifteen (15) day period shall be extended so long as Tenant is
            prosecuting such remedy continuously and with all due diligence.

            20.2 All costs and expenses incurred by Landlord in connection with
any performance by it for the account of Tenant shall be paid by Tenant to
Landlord within twenty (20) days after demand therefor accompanied by
appropriate supporting documentation. If any such cost or expense is not paid
when due and payable above, the same shall become due and payable by Tenant as
Additional Rent hereunder. If any Fixed Rent, Additional Rent or damages payable
hereunder by Tenant to Landlord is not paid when due as provided in this Lease,
the same shall bear interest at the Interest Rate from the due date thereof
until paid and the amount of interest shall be deemed Additional Rent hereunder.


                                       71
   83

This late payment charge will constitute liquidated damages and is intended to
compensate Landlord for its administrative costs resulting from Tenant's failure
to pay, and has been agreed upon by Landlord and Tenant, as a reasonable
estimate of the additional administrative costs. The actual cost in each
instance is extremely difficult, if not impossible, to determine.

            20.3 In the event of nonpayment by Tenant of any Additional Rent
becoming due hereunder, Landlord, in addition to any other right or remedy,
shall have the same rights and remedies as in the case of default by Tenant in
the payment of the Fixed Rent. Landlord reserves the right, without liability to
Tenant and without constituting any claim of constructive eviction, to suspend
furnishing or rendering to Tenant any property, material, labor, utility or
other service, wherever Landlord is obligated to furnish or render the same at
the expense of Tenant, in the event that (but only as long as) Tenant is in
arrears in paying Landlord therefor at the expiration often (10) days after
Landlord shall have given to Tenant notice demanding the payment of the arrears
and stating that in the absence of such payment Landlord will suspend the
furnishing or rendering of such property, material, labor, utility or other
service.

            Article 21. Consents.

            Wherever in this Lease either party's consent or approval is
required and such party has expressly agreed in this Lease that its consent or
approval shall not be unreasonably withheld, if such party shall withhold its
consent or approval, the other party shall in no event be entitled to and shall
not make any claim, and such other party hereby waives any claim, for money
damages (including a claim for money damages by way of set-off, counterclaim or
defense) based upon any assertion by such other party that the first party
unreasonably withheld or unreasonably delayed its consent or approval. Such
other party's sole remedies in such circumstance shall be either (i) an action
or proceeding to enforce the provision by way of specific performance,
injunction or declaratory judgment or (ii) an arbitration proceeding in
accordance with Article 35 hereof. Notwithstanding the foregoing (i) Tenant
shall have the right to claim money damages in the event Landlord is found by a
court of competent jurisdiction to have acted in bad faith in withholding its
consent or approval under any provision of this Lease which requires Landlord
not unreasonably to withhold the same (and such finding becomes final subject to
no further appeal), and (ii) Landlord shall have the right to claim money
damages in the event Tenant is found by a court of competent jurisdiction to
have acted in bad faith in withholding its consent or approval under any
provision of this Lease which requires Tenant not unreasonably to withhold the
same (and such finding becomes final subject to no further appeal). Unless
otherwise expressly set forth in this Lease, it is the express intent of the
parties that any consent of either party under this Lease shall be given or
required only in the sole, absolute and unfettered discretion of such party, and
may be withheld for any reason whatsoever. In any instance in which either party
has agreed to not unreasonably withhold its consent or approval:


                                       72
   84

                  (a) if no time period is specified such consent or approval
            shall be given or withheld within ten days, and

                  (b) if such party fails to give or withhold consent or
            approval within the time period specified in the applicable time
            period (as specified in clause (a) or elsewhere in this Lease as the
            case may be), the consent or approval of such party shall be deemed
            to have been given.

            Article 22. Insurance.

            22.1 Tenant shall not violate, or permit the violation of, any
condition imposed by the standard property insurance policy then issued for
office buildings in the City of New York, and shall not do, suffer or permit
anything to be done, or keep, suffer or permit anything to be kept in the
Premises that would increase the property or other casualty insurance rate on
the Building or the property therein over the rate that would otherwise then be
in effect (unless Tenant pays the resulting increased amount of premium as
provided below) or that would result in insurance companies of good standing
refusing to insure the Building or any of the property therein in amounts
reasonably satisfactory to Landlord, provided, however, that Tenant shall not be
subject to any liability or obligation under this paragraph by reason of the
proper use of the Premises for the purposes permitted by Article 5.

            22.2 If, by reason of any failure of Tenant to comply with the
provisions of this Lease, the rate of property insurance on the Building or
equipment or other property of Landlord or other tenants shall be higher than it
otherwise would be, Tenant shall reimburse Landlord for that part of the
premiums for property insurance paid by Landlord because of the act or omission
on the part of Tenant, which sum shall be deemed to be Additional Rent due
twenty (20) days after demand therefor accompanied by appropriate supporting
documentation, provided, however, that Tenant shall not be subject to any
liability or obligation under this paragraph by reason of the proper use of the
Premises for the purposes permitted by Article 5.

            22.3 In the event that any dispute should arise between Landlord and
Tenant concerning insurance rates, a schedule or make up of rates for the
Building or the Premises, as the case may be, issued by Insurance Service
Office, Inc. or other similar body making rates for property insurance for the
Building or the Premises, shall be presumptive evidence of the facts therein
stated and of the several items and charges in the property insurance rates then
applicable to the Building or the Premises.

            22.4 Tenant shall obtain and keep in full force and effect during
the term of this Lease at its own cost and expense the following insurance
coverages:

            (a) for the benefit of Tenant as insured and Landlord as an
      additional insured a commercial general liability insurance policy, in a
      broad form policy, affording


                                       73
   85

      protection in an amount of not less than $10,000,000 combined single limit
      coverage on a per occurrence basis, in respect of any and all claims for
      personal injury, death or property damage occurring in, upon, adjacent to,
      or connected with the Premises and any part thereof, and

            (b) fire and extended coverage in an amount adequate to cover the
      replacement of all personal property, fixtures, furnishings, equipment,
      improvements and installations, located in the Premises.

The commercial general liability insurance policy required by this Lease to be
maintained by Tenant shall name Landlord, CNA Financial Corporation, The
Continental Corporation and their subsidiaries as additional insureds during the
term of this Lease.

            22.5 Each insurance policy required by this Lease to be maintained
by Tenant shall provide that it will not be canceled, except upon thirty (30)
days advance written notice to Landlord. Each such policy shall be written by
insurance companies having a Best's rating of A or better that are admitted to
do business in the State of New York. The original insurance policies or
appropriate certificates evidencing compliance with Section 22.4 shall be
deposited with Landlord upon execution of this Lease and prior to each policy
expiration. In the event Tenant shall fail to procure and place any insurance
required by this Lease, and such failure shall continue for fifteen (15) days
after Landlord shall have given to Tenant a notice specifying such failure,
Landlord may, but shall not be obligated to, procure and place the same, in
which event the amount of the premium paid shall be reimbursed by Tenant to
Landlord upon demand and shall in each instance be collectible on the first day
of the month or any subsequent month following the date of payment by Landlord,
in the same manner as though the sums were additional rent reserved hereunder.

            22.6 Each party shall use commercially reasonable efforts to secure
an appropriate clause in, or an endorsement upon, each fire or extended coverage
or all-risk policy carried by it (including any business interruption or rental
loss insurance), pursuant to which the insurance company waives subrogation or
permits the insured, prior to any loss, to agree with a third party to waive any
claim it might have against that third party. If and to the extent that for any
policy period either party (the "procuring party") (i) is unable to secure the
aforesaid waiver or permission, or (ii) can secure the aforesaid waiver or
permission only upon payment of an additional charge, the procuring party shall
notify the other party (including, in any case under clause (ii) above, the
amount of such additional charge). In any case under clause (ii) above, if,
within fifteen (15) days of its receipt of such notice, the other party shall
agree pay the charge the procuring party shall obtain the aforesaid waiver or
permission for such policy period. Within ten (10) days request by either party,
the other party shall confirm to the requesting party whether the fire or
extended coverage or all-risk policy maintained by such other party includes the
waiver or permission referred to in this paragraph.


                                       74
   86

            Insofar as the insurance policies carried by it include the waiver
or permission referred to above, each party hereby releases the other party and
the agents and employees of the other party from any claim (including a claim
for negligence or a claim under any provision of this Lease) that such party
might otherwise have against the other party or the agents and employees of the
other party for any injury or damage covered by such policies to the Building or
the Premises or any property therein (or for the repair of or the costs of
repairing any such damage) or for any loss of rents or business interruption
covered by such policies.

            If either party shall fail to maintain insurance as required by this
Lease to be maintained by it, the aforesaid release shall also include any
injury or damage which would have been covered if such party had maintained
insurance as required by this Lease.

            The release set forth in this Section benefitting Tenant and its
agents and employees shall also benefit any subtenant and its agents and
employees provided that such subtenant shall grant to Landlord an equivalent
release.

            The release set forth in this Section shall not cover the deductible
portion of any loss; provided, however, that if the deductible limit of the
party suffering such loss exceeds $100,000 then such release shall cover the
portion of such deductible in excess of $100,000.

            22.7 Landlord shall obtain and keep in full force and effect during
the term of this Lease the following insurance coverages:

            (i) all-risk property insurance insuring the Building and the core
      and shell portions of the Premises for an amount equal to at least the
      full replacement cost value of the Building (excluding foundation and
      excavation costs) and the core and shell portions of the Premises against
      loss or damage due to fire and other casualties; and

            (ii) for the benefit of Landlord as insured and Tenant as additional
      insured a commercial general liability insurance, in a broad form policy,
      affording protection in an amount of not less than $10,000,000 combined
      single limit coverage on a per occurrence basis, in respect of any and all
      claims for personal injury, death or property damage occurring in, upon,
      adjacent to, or connected with the Building or any part thereof.

The commercial general liability insurance policy required by this Lease to be
maintained by Landlord shall name Tenant as additional insureds during the term
of this Lease.

            22.8 Each insurance policy required by this Lease to be maintained
by Landlord shall provide that it will not be canceled, except upon thirty (30)
days advance written notice to Tenant. Each such policy shall be written by
insurance companies having


                                       75
   87

a Best's rating of A or better that are admitted to do business in the State of
New York. Appropriate certificates evidencing compliance with Section 22.7 shall
be deposited with Tenant upon execution of this Lease and prior to each policy
expiration.

            22.9 All proceeds of the all-risk insurance required by this Lease
to be maintained by Landlord

                  (i) shall be applied to the performance of Landlord's repair
            and restoration obligations pursuant to Section 13.1, or

                  (ii) pending such application, shall be held by the holder of
            any Underlying Mortgage who shall have entered into with Tenant a
            non-disturbance agreement in accordance with clause (ii) of Section
            16.3 (or, if there shall be no such holder, by a depositary
            acceptable to Tenant) and no such proceeds shall be commingled with
            any other funds or applied to any other purpose until such repair
            and restoration obligations have been fully performed.

            Article 23. Brokerage Commission.

            Tenant represents and warrants that neither it nor any of its
partners, officers, employees or agents has dealt with any brokers in connection
with this Lease other than (i) Goldman, Sachs & Co. and The Georgetown Company
(collectively, the "Broker"), (ii) Cushman & Wakefield, Inc. ("C&W") and (iii)
Newmark & Company Real Estate, Inc. ("Newmark").

            Landlord shall be responsible for the payment of the commission due
to the Broker in connection with this Lease, specifically including the
commission due under that certain agreement of even date between Landlord and
Goldman, Sachs & Co. ("GS") and, if Landlord shall fail timely to pay any amount
due to GS thereunder, the provisions of Section 39.2 shall be applicable,
mutatis mutandis.

            Landlord agrees to indemnify, defend and hold the Tenant Indemnitees
harmless from and against any Claims for a brokerage, finder or other commission
or fee in connection with this Lease asserted against any Tenant Indemnitee by
Broker or C&W.

            Tenant represents and warrants that Newmark has waived all rights to
a commission payable by Landlord in connection with this Lease and any renewal,
extension, expansion or termination hereof. Tenant agrees to indemnify, defend
and hold the Landlord Indemnitees harmless from and against any Claims for a
brokerage, finder or other commission or fee in connection with this Lease
asserted against any Landlord Indemnitee by any broker, agent or finder (other
than Broker and C&W) with whom Tenant has dealt in connection with this Lease,
including Newmark.

   88

            Article 24. Satisfaction of Tenant's Remedies.

            Tenant shall look only to Landlord's interest and property in the
Building and Land (or the proceeds thereof, including insurance proceeds to
which recourse is available, subject to the rights of the holder of any
Underlying Mortgage or Underlying Lease) for the satisfaction of Tenant's
remedies for the collection of a judgment (or other judicial process) requiring
the payment of money by Landlord in the event of any default by Landlord
hereunder, and no other property or assets of Landlord or its partners or
principals, disclosed or undisclosed, shall be subject to levy, execution, or
other enforcement procedure for the satisfaction of Tenant's remedies under or
with respect to this Lease, the relationship of Landlord and Tenant hereunder or
Tenant's use and occupancy of the Premises.

            Article 25. Landlord's Payments to Tenant.

            25.1 Landlord shall pay to Tenant with respect to each portion of
the Premises the amounts provided for herein (the "Landlord Monthly Payments").

            With respect to each Applicable Portion, a monthly amount, computed
at the following per annum rates: (a) during the initial Term of this Lease,
$1.65 per annum per square foot of rentable area (subject to the provisions of
the next sentence), (b) during the First Renewal Term of this Lease, an amount
per annum per square foot of rentable area equal to the Renewal Term Initial
Cleaning Cost determined pursuant to Article 27 with respect to the First
Renewal Term, and (c) during the Second Renewal Term of this Lease, an amount
per annum per square foot of rentable area equal to the Renewal Term Initial
Cleaning Cost determined pursuant to Article 27 with respect to the Second
Renewal Term. No such payments under clause (a) of this paragraph shall be
required with respect to any Applicable Portion in respect of any period prior
to the Rent Commencement Date with respect to such Applicable Portion.

            With respect to each Accepted Offer Space becoming a part of the
Premises during the initial Term of this Lease, a monthly amount, computed at
the following per annum rates: (a) during the balance of such initial Term, an
amount per annum per square foot of rentable area equal to the Offer Space
Initial Cleaning Cost determined pursuant to Article 26 with respect to such
Accepted Offer Space, and (b) during the First Renewal Term of this Lease, an
amount per annum per square foot of rentable area equal to the Renewal Term
Initial Cleaning Cost determined pursuant to Article 27 with respect to the
First Renewal Term, and (c) during the Second Renewal Term of this Lease, an
amount per annum per square foot of rentable area equal to the Renewal Term
Initial Cleaning Cost determined pursuant to Article 27 with respect to the
Second Renewal Term.

            With respect to each Accepted Offer Space becoming a part of the
Premises during the First Renewal Term of this Lease, a monthly amount, computed
at the following per annum rates: (a) during the balance of such First Renewal
Term, an amount per annum per square foot of rentable area equal to the Offer
Space Initial Cleaning Cost determined


                                       77
   89

pursuant to Article 26 with respect to such Accepted Offer Space, and (b) during
the Second Renewal Term of this Lease, an amount per annum per square foot of
rentable area equal to the Renewal Term Initial Cleaning Cost determined
pursuant to Article 27 with respect to the Second Renewal Term.

            With respect to each Accepted Offer Space becoming a part of the
Premises during the Second Renewal Term of this Lease, a monthly amount,
computed at the following per annum rate: during the balance of such Second
Renewal Term, an amount per annum per square foot of rentable area equal to the
Offer Space Initial Cleaning Cost determined pursuant to Article 26 with respect
to such Accepted Offer Space.

            25.2 The Landlord Monthly Payments shall be due on the first day of
each month; provided, however, that (a) if the Rent Commencement Date with
respect to any Applicable Portion shall be on other than the first day of a
month, the initial Landlord Monthly Payment with respect to such Applicable
Portion shall be computed on a pro-rata basis and shall be due on such Rent
Commencement Date, and (b) if any Accepted Offer Space shall become a part of
the Premises on other than the first day of a month, the initial Landlord
Monthly Payment with respect to such Accepted Offer Space shall be computed on a
pro-rata basis and shall be due on the day on which such Accepted Offer Space
becomes a part of the Premises.

            Landlord shall pay the Landlord Monthly Payment as and when the same
shall become due and payable to Tenant at its office in the United States of
America, or any other place or places in the United States of America as Tenant
shall designate to Landlord, in cash or by check, payable to Tenant in United
States currency, without demand therefor and without any setoff or deduction
whatsoever.

            If any Landlord Monthly Payment is not paid when due as provided in
this Lease, (a) the same shall bear interest at the Interest Rate from the due
date thereof until paid, and (b) Tenant shall have the right to set-off the
amount thereof, and such interest, against the Fixed Rent under this Lease.

            Article 26. Tenant's Right to Lease Additional Space.

            26.1 Landlord shall not hereafter lease any space in the Building
(including by way of renewal, extension or expansion of any lease), other than:

                  (a) pursuant to the exercise by the tenant under any lease in
            effect on the date of this Lease of any renewal, extension or
            expansion right or option contained in such lease as of the date of
            this Lease;

                  (b) pursuant to the exercise by the tenant under any lease
            subsequently entered into by Landlord of any renewal or extension
            right or


                                       78
   90

            option contained in such lease as of the date of the original
            entering into of such lease; or

                  (c) pursuant to Section 26.4 below.

As used in this Article 26, the term "lease" shall include (i) a license or
other agreement providing for occupancy, and (ii) occupancy by Landlord or any
other person without such a lease, license or other agreement. Landlord
represents and warrants to Tenant that attached hereto as Exhibit S is a true
and accurate schedule of each lease in effect on the date of this Lease, the
premises demised thereby, the expiration date thereof, and all renewal,
extension or expansion rights or options contained therein as of the date of
this Lease.

            26.2 Landlord may give one or more Offer Notices (as hereinafter
defined) to Tenant at any time. The term "Offer Notice" as used herein shall
mean a notice (a) referring to this Article 26, (b) describing the premises to
which it relates (the "Offer Space") and, if the Offer Space includes a portion
less than all of the rentable area on any floor, including an outline floor plan
of the Offer Space and a statement of the rentable area thereof in accordance
with Section 26.11, and (c) setting forth the date (which shall be (i) no
earlier than the last day on which, pursuant to Section 26.3, Tenant is entitled
to give an Acceptance Notice (as hereinafter defined) in response to such Offer
Notice and (ii) no later than 270 days after the date of the Offer Notice) on
which, if Tenant exercise its right pursuant to Section 26.3 to lease such Offer
Space, Landlord reasonably believes (on the basis of written agreements then in
effect) it will be able to deliver to Tenant vacant possession thereof (the
"Scheduled Offer Space Delivery Date"). Landlord shall give an Offer Notice with
respect to each portion of the Building no later than 30 days after the date on
which Landlord becomes entitled to do so. If pursuant to the provisions of any
other lease (a "Recapture Provision") Landlord shall become entitled to
recapture any space in the Building in connection with a proposed assignment or
sublease, Landlord shall, within three (3) business days of its receipt of the
notice from the other tenant entitling Landlord to recapture, give to Tenant an
Offer Notice with respect to such space; such Offer Notice shall, in addition to
the information required by the preceding sentence to be included therein,
indicate (a) that it relates to space which Landlord is entitled to recapture
and (b) the last day on which Landlord is permitted by the terms of the
applicable lease to exercise its recapture right (the "Landlord's Exercise
Deadline Date"). Landlord shall not waive or amend any lease so as to eliminate
any Recapture Provision. Each Offer Notice shall constitute (a) an offer by
Landlord to lease the Offer Space covered thereby to Tenant on the terms set
forth in this Article 26, and (b) a representation by Landlord that all leases
covering any of such Offer Space have expired or been terminated or, pursuant to
the terms thereof or other written agreements then in effect, will expire or
terminate on or prior to the Scheduled Offer Space Delivery Date set forth in
such Offer Notice. 

            26.3 Tenant shall have the right, by notice to Landlord given within
twenty (20) business days of its receipt of any Offer Notice (an "Acceptance
Notice"), to lease all or any portion of the Offer Space covered by such Offer
Notice; provided, however, that


                                       79
   91

                  (a) if Tenant elects to lease and include in its Acceptance
            Notice any of such Offer Space on any floor of the Building it shall
            elect to lease and include in its Acceptance Notice all of such
            Offer Space on such floor of the Building;

                  (b) if the Offer Space shall include all of three or more full
            floors contiguous to one another (a "Multi-Full-Floor Contiguous
            Block") and Tenant elects to lease and include in its Acceptance
            Notice a portion less than all of such Multi-Full-Floor Contiguous
            Block the balance thereof not so leased and included shall be either
            (i) one such full floor, or (ii) two or more full floors contiguous
            to one another; and

                  (c) in the case of any Offer Notice given under the second
            sentence of Section 26.2, the Acceptance Notice must be given, if at
            all, no later than the earlier of (i) the date provided for above in
            this Section 26.3 and (ii) the second business day prior to
            Landlord's Exercise Deadline Date set forth in the Offer Notice.

Time shall be of the essence with respect to the giving of any Acceptance
Notice. The space as to which Tenant gives a timely Acceptance Notice conforming
to the provisions of this Section 26.3 is herein called an "Accepted Offer
Space".

            26.4 If in response to any Offer Notice Tenant shall fail timely to
give an Acceptance Notice then Landlord shall be permitted to lease all or any
portion of the Offer Space covered by such Offer Notice to any person or persons
for delivery no earlier than the Scheduled Offer Space Delivery Date set forth
in such Offer Notice; provided, however, that immediately subsequent to the
original entering into of any such lease the space covered thereby shall again
become subject to this Article 26 such that Landlord shall not (except as
permitted by clause (b) of Section 26.1) subsequently lease such space except
pursuant to the operation of this Section 26.4 with respect to a subsequent
Offer Notice given to Tenant with respect thereto. If in response to any Offer
Notice Tenant shall timely give an Acceptance Notice with respect to less than
all of the Offer Space covered by such Offer Notice then Landlord shall be
permitted to lease all or any portion of the balance of such Offer Space covered
by such Offer Notice to any person or persons for delivery no earlier than the
Scheduled Offer Space Delivery Date set forth in such Offer Notice; provided,
however, that immediately subsequent to the original entering into of any such
lease the space covered thereby shall again become subject to this Article 26
such that Landlord shall not (except as permitted by clause (b) of Section 26.1)
subsequently lease such space except pursuant to the operation of this Section
26.4 with respect to a subsequent Offer Notice given to Tenant with respect
thereto.

            26.5 Tenant may only exercise its right to lease any Offer Space,
and an exercise thereof shall only be effective, if at the time of Tenant's
exercise of its right and on the applicable Scheduled Offer Space Delivery Date,
the following conditions are satisfied:


                                       80
   92

(i) this Lease is in full force and effect, (ii) no monetary or material
non-monetary default on the part of Tenant continuing beyond any applicable
notice or cure period then exists under this Lease, and (iii) the rentable area
of the Premises then subject to this Lease and not then subject to any sublease
(excluding subleases made under Section 12.7 and 12.8) shall be at least 250,000
square feet of rentable area.

            26.6 If Tenant shall timely give an Acceptance Notice then on the
applicable Scheduled Offer Space Delivery Date Landlord shall deliver vacant
possession of the Accepted Offer Space to Tenant and effective upon the later of
(i) such Scheduled Offer Space Delivery Date or (ii) the date of such delivery
(such later date being herein called the "Offer Space Commencement Date") the
Accepted Offer Space shall be included in the Premises, subject to all of the
terms, conditions and provisions of this Lease (including expiration date and
renewal options) except that:

            (a) the Fixed Rent for such Accepted Offer Space shall be as
      provided in Section 26.9;

            (b) Such Accepted Offer Space shall be leased to Tenant in its then
      "as is" condition;

            (c) The number of rentable square feet of the Accepted Offer Space
      shall be determined as provided for in Section 26.11; and

            (d) Tenant's liability under Section 4.2(a) and 4.2(b) with respect
      to such Accepted Offer Space shall be computed separately and, for
      purposes thereof, the Base Year shall be deemed to be the calendar year in
      which the Offer Space Commencement Date shall occur.

Within thirty (30) days after the Offer Space Commencement Date, if requested by
either party hereto, Landlord and Tenant shall enter into a written instrument
confirming the terms, conditions and provisions applicable to the lease of the
Accepted Offer Space as determined in accordance with this Article; provided,
however, that the failure of either party to execute such instrument shall not
affect the rights and duties of the parties hereunder.

            26.7 If Landlord shall deliver vacant possession of a portion of any
Accepted Offer Space less than all thereof then Tenant shall have the right, by
notice to Landlord given no later than the later of (i) the Scheduled Offer
Space Delivery Date, or (ii) the tenth (10th) day after the day of such delivery
and notice thereof from Landlord to Tenant, to

                  (a) accept all of such portion or all of such portion on any
            one or more floors of the Building (the space which Tenant so
            accepts being herein called a "Partial Accepted Offer Space") and
            reject the balance of such portion; or


                                       81
   93

                  (b) reject all of such portion.

            If Tenant shall give notice under clause (a) above then

                  (i) Section 26.6 shall be applicable to the Partial Accepted
            Offer Space as of the later of (x) the Scheduled Offer Space
            Delivery Date, or (y) the day of such delivery, and

                  (ii) Landlord shall remain obligated to deliver vacant
            possession of the balance of such Accepted Offer Space in accordance
            with Section 26.6 as soon as Landlord is able to do so (and Section
            26.6 shall be separately applicable thereto), subject to Section
            26.8 and, in the case of a subsequent delivery of only a portion of
            such balance, this Section 26.7.

            If Tenant shall give notice under clause (b) above then Landlord
shall remain obligated to deliver vacant possession of such Accepted Offer Space
in accordance with Section 26.6 as soon as Landlord is able to do so (and
Section 26.6 shall be applicable thereto), subject to Section 26.8 and, in the
case of a subsequent delivery of only a portion of such Accepted Offer Space,
this Section 26.7.

            26.8 Landlord shall not be subject to any liability for failure to
deliver possession of all or any portion of any Accepted Offer Space in the
event that Landlord is unable to deliver to Tenant possession thereof on the
applicable Scheduled Offer Space Delivery Date by reason of the holding over in
the space by a prior tenant thereof, but Landlord shall use commercially
reasonable efforts, including prosecution of an eviction action, to obtain
possession of the Accepted Offer Space; nor shall such failure affect either the
validity of this Lease or the obligations of Landlord or Tenant hereunder.

            Notwithstanding the foregoing, if for any reason Landlord shall fail
to deliver vacant possession of any portion of any Accepted Offer Space on or
before the 60th day following the applicable Scheduled Offer Space Delivery Date
then Tenant shall have the right, by notice to Landlord given at any time prior
to delivery of vacant possession of all of such Accepted Offer Space, to rescind
its Acceptance Notice as to all of such Accepted Offer Space (excluding any
Partial Accepted Offer Space theretofore accepted by Tenant) or as to all of
such Accepted Offer Space (excluding any Partial Accepted Offer Space
theretofore accepted by Tenant) on any one or more floors of the Building.

            26.9 The annual Fixed Rent per square foot of rentable area for any
Accepted Offer Space shall be an amount equal to the annual fair market rental
value of such Accepted Offer Space per square foot of rentable area for a term
commencing on the Scheduled Offer Space Delivery Date and ending as provided in
this Article 26 and otherwise on the terms and conditions provided for in
Section 26.6 (the "Offer Space Fair Market Rent"), multiplied by ninety-five
percent (95%).


                                       82
   94

            The Offer Space Fair Market Rent shall be determined on the basis of
the use of the Accepted Offer Space as offices (in the case of Accepted Offer
Space on or above the mezzanine level) or as lobby or basement space (in the
case of Accepted Offer Space below the mezzanine level) assuming that (i) the
Accepted Offer Space is free and clear of all leases and tenancies, (ii) the
Accepted Offer Space is available in the then rental market for comparable
first-class office buildings in Manhattan, (iii) Landlord has had a reasonable
time to locate a tenant who rents with the knowledge of the uses to which the
Accepted Offer Space can be adapted, (iv) neither Landlord nor the prospective
tenant is under any compulsion to rent and (v) the prospective tenant has the
creditworthiness of Tenant.

            If and to the extent that any lease used as a reference (or
"comparable") by the persons determining the Offer Space Fair Market Rent
provides for any payments, costs and concessions by the landlord thereunder
(including by way of example, brokerage commissions, takeover costs,
construction costs, tenant construction allowances and rent abatements), such
persons shall, in determining such Offer Space Fair Market Rent, adjust the base
rent provided for in such lease downward to reflect that in connection with the
leasing of the Offer Space to Tenant the Landlord will incur no such payments,
costs or concessions.

            The persons determining the Offer Space Fair Market Rent shall (A)
assume that this Lease (i) requires Landlord to provide office cleaning to the
Accepted Offer Space, and (ii) requires Tenant to bear only the escalation in
the costs thereof in excess of the costs thereof during the calendar year in
which the Offer Space Commencement Date occurs, and (B) also determine the
estimated cost of providing office cleaning to the Accepted Offer Space during
the calendar year in which the Offer Space Commencement Date occurs (the "Offer
Space Initial Cleaning Cost").

            26.10 For purposes of determining the Offer Space Fair Market Rent,
the following procedure shall apply:

            (a) Landlord and Tenant shall, at the location in the County of New
      York and the time on the 20th business day after the day of the Acceptance
      Notice specified by Landlord reasonably in advance, exchange their
      respective written determinations of (i) the Offer Space Fair Market Rent,
      and (ii) the Offer Space Initial Cleaning Cost, each of which shall be
      stated as a dollar amount per square foot of rentable area (Landlord's
      determination of the Offer Space Fair Market Rent and the Offer Space
      Initial Cleaning Cost is referred to as "Landlord's Determination" and
      Tenant's determination of the Offer Space Fair Market Rent and the Offer
      Space Initial Cleaning Cost is referred to as "Tenant's Determination").
      If either party shall fail to tender delivery of its determination on the
      date and at the time and location provided for above (or if Landlord shall
      fail to so specify such time and location as provided for above), the
      other party may withhold its determination and, by notice to the failing
      party, may specify a new date, time and location in the County of New York
      for such exchange and, if such failing party shall again fail to tender
      delivery


                                       83
   95

      of its determination on such new date and at such new time and location,
      then the determination of such other party shall constitute the Offer
      Space Fair Market Rent and the Offer Space Initial Cleaning Cost.

            (b) If the parties shall have exchanged determinations in accordance
      with the foregoing, they shall attempt to agree upon the Offer Space Fair
      Market Rent and the Offer Space Initial Cleaning Cost. If, within ten (10)
      days after the date of such exchange, they have not so agreed they shall
      attempt to agree upon an independent real estate appraiser to act
      hereunder. If, within twenty (20) days after the date of such exchange,
      they have not so agreed upon such an independent real estate appraiser,
      such independent real estate appraiser shall be appointed by the American
      Arbitration Association. The independent real estate appraiser so agreed
      upon by the parties or so appointed is herein called the "Offer Space
      Appraiser". The fee of the Offer Space Appraiser and of the American
      Arbitration Association shall be borne equally by Landlord and Tenant.
      Each party shall pay its own counsel fees and expenses, if any, in
      connection with any determination under this Article.

            (c) The Offer Space Appraiser shall conduct such hearings and
      investigations as he or she may deem appropriate and shall, within thirty
      (30) days of the date of his or her designation, choose

                  (i) either Landlord's Determination of the Offer Space Fair
            Market Rent or Tenant's Determination of the Offer Space Fair Market
            Rent, and

                  (ii) either Landlord's Determination of the Offer Space
            Initial Cleaning Cost or Tenant's Determination of the Offer Space
            Initial Cleaning Cost

      (it being understood that the Offer Space Appraiser may choose Landlord's
      Determination of one and Tenant's Determination of the other) and the
      choice by the Appraiser shall be conclusive and binding upon Landlord and
      Tenant.

            (d) The Offer Space Appraiser appointed pursuant to this Article
      shall be an independent real estate appraiser with at least ten (10)
      years' experience in valuation of properties that are similar in character
      to the Building, and a member of the Appraisal Institute (or its
      successor). The Offer Space Appraiser shall not have the power to add to,
      modify or change any of the provisions of this Lease.

            (e) It is expressly understood that any determination of the Offer
      Space Fair Market Rent and the Offer Space Initial Cleaning Cost pursuant
      to this Article shall be based on the criteria stated in this Article.

            26.11 The number of square feet of rentable area of any floor shall
be as set forth on Exhibit B. The number of square feet of rentable area of any
portion of any floor


                                       84
   96

less than all thereof shall be determined by allocating of the number of square
feet of rentable area of such floor to the respective usable portions thereof,
so that the aggregate number of square feet of rentable area of all such usable
portions shall equal the number of square feet of rentable area of such floor as
set forth on Exhibit B. Any dispute with respect to the number of square feet of
rentable area of any such portion shall be subject to arbitration pursuant to
Article 35.

            26.12 After a determination has been made of the Offer Space Fair
Market Rent and the Offer Space Initial Cleaning Cost for any Accepted Offer
Space, the parties shall execute and deliver to each other an instrument
setting forth the Offer Space Fair Market Rent, the Offer Space Initial Cleaning
Cost and the Offer Space Fixed Rent for such Accepted Offer space as determined
pursuant to this Article; provided however, that failure of either party to
execute a written supplement shall not affect the rights and duties of the
parties hereunder.

            26.13 If the final determination of the Offer Space Fair Market Rent
and the Offer Space Initial Cleaning Cost with respect to any Accepted Offer
Space shall not be made on or before the Offer Space Commencement Date with
respect thereto, then pending such determination (and subject to retroactive
adjustment as provided below), payments of Fixed Rent and Landlord Monthly
Payment with respect to the Accepted Offer Space shall be made based upon the
assumption that the Office Space Arbitrator will choose Landlord's Determination
of the Offer Space Fair Market Rent and of the Offer Space Initial Cleaning
Cost. If the Offer Space Arbitrator chooses Tenant's Determination of the Offer
Space Fair Market Rent or the Offer Space Initial Cleaning Cost (or if the Offer
Space Fair Market Rent or Offer Space Initial Cleaning Cost as finally
determined is otherwise different from Landlord's Determination thereof), Tenant
shall be entitled to a credit against the Rent equal to the amount of Tenant's
overpayment of Fixed Rent or Landlord's underpayment of Landlord Monthly
Payment, computed retroactively to the Offer Space Commencement Date. If the
amount of such credit shall exceed $100,000 Landlord shall, if Tenant shall so
request, pay such amount to Tenant with twenty (20) days of such request.

            26.14 Tenant shall have the right, upon reasonable notice to
Landlord, to enter any Offer Space at reasonable times for purposes of
inspection and measurement from time to time during the period beginning on the
date of any Offer Notice and ending on the last day on which Tenant is entitled
to give an Acceptance Notice with respect thereto; provided, however, that if
Tenant shall timely give an Acceptance Notice such right shall continue until
the Offer Space Commencement Date. Landlord may accompany Tenant during any such
entry.

            Article 27. Renewal Term.

            27.1 Tenant shall have the option (the "Renewal Option") to extend
the term of this Lease for two (2) additional periods of five (5) years each
(each a "Renewal Term").


                                       85
   97

The first Renewal Term (the "First Renewal Term") shall commence on the date
immediately succeeding the Initial Term Expiration Date and shall end on the
fifth (5th) anniversary of the Initial Term Expiration Date.

            The second Renewal Term (the "Second Renewal Term") shall commence
on the date immediately succeeding the fifth (5th) anniversary of the Initial
Term Expiration Date and shall end on the tenth (10th) anniversary of the
Initial Term Expiration Date

            Each Renewal Option may be exercised with respect to:

                  (i) the entire Premises then subject to this Lease; or

                  (ii) the Base Premises only, if the Base Premises are then
            subject to this Lease (whether or not other premises are also then
            subject to this Lease); or

                  (iii) the Base Premises and the Special Purpose Areas then
            subject to this Lease only, if the Base Premises and any or all of
            the Special Purposes Areas are then subject to this Lease (whether
            or not other premises are also then subject to this Lease);

provided, however, that if any Renewal Option is exercised with respect to
either (X) the premises referred to in clause (ii) above or (Y) the premises
referred to in clause (iii) above, then such Renewal Option may also be
exercised with respect to such other portions of the Premises then subject to
this Lease as Tenant shall elect, except that in making its election under this
proviso Tenant shall not exclude from the Renewal Premises any Full Premises
Floor if both the floor immediately above such Full Premises Floor and the floor
immediately below such Full Premises Floor are Full Premises Floors and are
included in such Renewal Premises.

            The premises as to which Tenant exercises a Renewal Option are
herein called the "Renewal Premises" with respect to such Renewal Option.

            Each Renewal Option shall be exercisable by Tenant delivering to
Landlord notice of Tenant's exercise thereof (a "Renewal Notice"), identifying
the Renewal Premises, at least 18 months prior to the first day of the Renewal
Term in question. Time is of the essence with respect to the giving of the
Renewal Notice. Upon the giving of the Renewal Notice with respect to the Second
Renewal Term, Tenant shall have no further right or option to extend or renew
the term of this Lease or any Renewal Term.

            Notwithstanding the foregoing, Tenant may only exercise a Renewal
Option, and an exercise thereof shall only be effective, if at the time of
Tenant's exercise of such Renewal Option and on the day preceding the
commencement of the Renewal Term in question, the following conditions are
satisfied, (i) this Lease is in full force and effect and


                                       86
   98

(ii) no monetary or material non-monetary default on the part of Tenant
continuing beyond any applicable notice or cure period then exists under this
Lease.

            27.2 If Tenant exercises a Renewal Option, the Renewal Term shall be
upon the same terms, covenants and conditions as those contained in this Lease,
except that

                  (i) the Fixed Rent with respect to the Office Area being a
            part of the Renewal Premises shall be the Office Area Renewal Fixed
            Rent as determined pursuant to this Article 27,

                  (ii) the Fixed Rent with respect to the Special Purpose Areas
            being a part of the Renewal Premises shall be 53% percent of the
            Office Area Renewal Fixed Rent as determined pursuant to this
            Article 27,

                  (iii) the Fixed Rent with respect to the Non-Office Areas
            being a part of the Renewal Premises shall be 50% percent of the
            Office Area Renewal Fixed Rent as determined pursuant to this
            Article 27,

                  (iv) the Base Year shall be the calendar year in which the
            first day of the Renewal Term occurs, and

                  (v) the provisions of this Article relative to Tenant's right
            to renew the term of this Lease (x) shall be limited during the
            First Renewal Term to the right to exercise the Renewal Option with
            respect to the Second Renewal Term and (y) shall not be applicable
            during the Second Renewal Term.

            27.3 For annual Fixed Rent per square foot of rentable area of
Office Area for any Renewal Term (the "Office Area Renewal Fixed Rent") shall be
an amount equal the annual fair market rental value of the Office Area for a
five-year term commencing on the first day of the Renewal Term in question and
otherwise on the terms and conditions applicable to the Office Area provided for
in this Article 27 (the "Renewal Term Fair Market Rent"), multiplied by
ninety-five (95%).

            The Renewal Term Fair Market Rent shall be determined on the basis
of the use of the Office Area as offices assuming that (i) the Office Area is
free and clear of all leases and tenancies (including this Lease), (ii) the
Office Area is available in the then rental market for comparable first-class
office buildings in Manhattan, (iii) Landlord has had a reasonable time to
locate a tenant who rents with the knowledge of the uses to which the Office
Area can be adapted, and (iv) neither Landlord nor the prospective tenant is
under any compulsion to rent, and (v) the prospective tenant has the
creditworthiness of Tenant.

            If and to the extent that any lease used as a reference (or
"comparable") by the persons determining the Renewal Term Fair Market Rent
provides for any payments, costs and concessions by the landlord thereunder
(including by way of example, brokerage


                                       87
   99

commissions, takeover costs, construction costs, tenant construction allowances
and rent abatements), such persons shall, in determining such Renewal Term Fair
Market Rent, adjust the base rent provided for in such lease downward to reflect
that in connection with the renewal of this Lease the Landlord will incur no
such payments, costs or concessions.

            The persons determining the Renewal Term Fair Market Rent shall (A)
assume that this Lease (i) requires Landlord to provide office cleaning to the
Premises, and (ii) requires Tenant to bear only the escalation in the costs
thereof in excess of the costs thereof during the calendar year in which the
Renewal Term commences, and (B) also determine the estimated cost of providing
office cleaning to the Premises during the calendar year in which the Renewal
Term commences (the "Renewal Term Initial Cleaning Cost").

            27.4 For purposes of determining the Renewal Term Fair Market Rent,
the following procedure shall apply:

            (a) Landlord and Tenant shall, at the location in the County of New
      York, at the time and on a business day not earlier than 20 months prior
      to the first day of the Renewal Term in question and not later than 19
      months prior to the first day of the Renewal Term in question specified by
      Landlord (by notice to Tenant given at least thirty (30) days prior to the
      date set forth therein), exchange their respective written initial
      determinations of the Renewal Term Fair Market Rent and the Renewal Term
      Initial Cleaning Cost, each of which shall be stated as a dollar amount
      per square foot of rentable area of Office Area (Landlord's initial
      determination of the Renewal Term Fair Market Rent and the Renewal Term
      Initial Cleaning Cost is referred to as "Landlord's Initial Determination"
      and Tenant's determination of the Renewal Term Fair Market Rent and the
      Renewal Term Initial Cleaning Cost is referred to as "Tenant's Initial
      Determination"). If either party shall fail to tender delivery of its
      determination on the date and at the time and location provided for above
      (or if Landlord shall fail to so specify such date, time and location as
      provided for above), the other party may withhold its determination and,
      by notice to the other party given at least five (5) days prior to the
      date set forth therein, may specify a new date, time and location in the
      County of New York for such exchange and, if such failing party shall
      again fail to tender delivery of its determination on such new date and at
      such new time and location, then the determination of such other party
      shall constitute the Renewal Term Fair Market Rent and the Renewal Term
      Initial Cleaning Cost.

            (b) If the parties shall have exchanged determinations in accordance
      with the foregoing, they shall attempt to agree upon the Renewal Term Fair
      Market Rent and the Renewal Term Initial Cleaning Cost. If, within ten
      (10) days after the date of such exchange, they have not so agreed they
      shall attempt to agree upon an independent real estate appraiser to act
      hereunder. If, within twenty (20) days after the date of such exchange,
      they have not so agreed upon such an independent real estate appraiser,
      such independent real estate appraiser shall be appointed by the American
      Arbitration Association. The independent real estate appraiser so agreed


                                       88
   100

      upon by the parties or so appointed is herein called the "Renewal Term
      Appraiser". The fee of the Renewal Term Appraiser and of the American
      Arbitration Association shall be borne equally by Landlord and Tenant.
      Each party shall pay its own counsel fees and expenses, if any, in
      connection with any determination under this Article.

            (c) The Renewal Term Appraiser, by notice to the parties, shall
      establish a date, time and location in the County of New York, no earlier
      than 10 days after the date of such notice, at which either party may, if
      it elects, deliver to the Renewal Term Appraiser a revised written
      determination of the Renewal Term Fair Market Rent and/or the Renewal Term
      Initial Cleaning Cost (stated as a dollar amount per square foot of

Term shall be made based upon the assumption that the Renewal Term Appraiser
will choose Landlord's Determination of the Renewal Term Fair Market Rent and of
the Renewal Term Initial Cleaning Cost. If the Renewal Term Appraiser chooses
Tenant's Determination of the Offer Space Fair Market Rent or of the Renewal
Term Initial Cleaning Cost (or if the Renewal Term Fair Market Rent of Renewal
Term Initial Cleaning Cost as finally determined is otherwise different from

replacement operator would result in a net increase in Landlord's costs of
operating the dining facility, Landlord shall not be required to comply with
such direction or request or so to replace the operator of the dining facility
unless Tenant agrees to pay such net increase in costs.

            Landlord shall have the right, upon not less than 120 days notice to

to time with respect to the dining facility and its operations, and, if Tenant

direction or request or so to replace the operator of the cafeteria unless
Tenant agrees to pay such net increase in costs.

appropriate for a class A downtown Manhattan office building. Neither the size
nor the operating hours or services shall hereafter be reduced below the size,
operating hours or services in effect on the date hereof. In no event shall
Tenant's rights in, to and with respect to the conference center be less, in any
respect, than the rights of any other tenant or other person. Tenant (and, if
and to the extent that Tenant so elects, its subtenants) and their respective
employees and guests shall be entitled to use such conference center on a
non-exclusive basis. At Tenant's request, Landlord shall consult with Tenant
with respect all aspects of the conference center operation. The facilities of
the conference center shall be subject to reservation by tenants of the Building
on a "first-reserved, first-served" basis; provided, however, that

                  (i) except for Tenant and SSL no tenant of the Building or
            other person shall be permitted to reserve any room or facility
            prior to 30 days in advance, and

                  (ii) Tenant and SSL shall be entitled to reserve any room or
            facility as far in advance as either desires.

Landlord shall comply with Tenant's directions and requests from time to time
with respect to the conference center and its operations, and, if Tenant shall
so request from time to time, Landlord shall replace the operator of the
conference center with an operator acceptable to Tenant; provided, however, that
(a) Tenant shall not have the right to require Landlord to replace the operator
of the conference center within one year of such the operator's having been
previously replaced at Tenant request, and (b) if any such direction or request
or replacement operator would result in a net increase in Landlord's costs of
operating the conference center, Landlord shall not be required to comply with
such direction or request or replace the operator of the conference unless
Tenant agrees to pay such net increase in costs.

services shall hereafter be reduced below the size, operating hours or services
in effect on the date hereof. In no event shall Tenant's rights in, to and with
respect to the health and exercise facility be less, in any respect, than the
rights of any other tenant or other person. Tenant (and, if and to the extent
that Tenant so elects, its subtenants) and their respective employees and guests
shall be entitled to use such health and exercise facility on a non-exclusive
basis. At Tenant's request, Landlord shall consult with Tenant with respect all
aspects of the health and exercise facility operation. Landlord shall furnish
Tenant with copies of, and shall meet with Tenant to discuss, monthly financial
statements, quarterly operational reviews, periodic (at least quarterly)
sanitation reviews and all other documentation commonly created in connection
with the operation of a health and exercise facility appropriate for a class A
office building. Landlord shall comply with Tenant's directions and requests
from time to time with respect to the dining facility and its operations, and,
if Tenant shall so request from time to time, Landlord shall replace the
operator of the health and exercise facility with an operator acceptable to
Tenant; provided, however, that (a) Tenant shall not have the right to require
Landlord to replace the operator of the health and exercise facility within one
year of such the operator's having been previously replaced at Tenant request,
and (b) if any such direction or request or replacement operator would result in
a net increase in Landlord's costs of operating the health and exercise
facility, Landlord shall not be required to comply with such direction or
request or so to replace the operator of the health and exercise facility unless
Tenant agrees to pay such net increase in costs.

            Landlord shall have the right, upon not less than 120 days notice to
Tenant, to terminate the operation of and close the health and exercise
facility; provided, however, that Tenant, by notice to Landlord given within

                        (b) that SSL has agreed that Landlord may transfer SSL's

            Landlord shall perform and satisfy all of the obligations to SSL
under the agreement referred to in clause (b) of the first paragraph of this

      for the preceding two (2) years for which annual statements have been
      furnished to tenants, including copies of annual escalation billing and
      reconciliation for all such tenants for all such years.


                                       107
   119

            Tenant shall have a period of thirty (30) days from the date it
receives Landlord's Offer Notice and the Property Information within which to
notify Landlord that it desires to purchase the Land and/or Building, as
applicable (such Land and/or Building, the "Property"), at the Offer Price (the
"Tenant's Acceptance"). During such thirty (30) day period Tenant shall have the
right, subject to the terms and conditions of Section 37.5, to examine and copy
all pertinent books and records of Landlord and its managing agent relating to
the Property ("Books and Records").

            If Tenant provides Tenant's Acceptance to Landlord, then Landlord
shall sell, and Tenant shall purchase, the Property at the price set forth in
the Offer (the "Offer Price") and otherwise on terms and conditions customary
for sales of large Manhattan office buildings. During the forty-five (45) days
after the date of this Lease, the parties shall endeavor to agree upon and
confirm in writing such terms and conditions, but the failure of the parties so
to agree shall not affect their rights and obligations under this Article 37.

            After providing Tenant's Acceptance. Tenant shall have the right to
assign its right to purchase to a wholly-owned affiliate and, in such instance,
Landlord shall convey title to the assignee. If Tenant (or such wholly-owned
affiliate) shall acquire the Land or Building pursuant to this Article 37, it
shall retain title thereto for at least one year after the closing of such
acquisition.

            37.2 If Tenant shall fail to give Tenant's Acceptance pursuant to
the terms set forth above, Tenant shall, subject to the last sentence of this
Section 37.2, be deemed to have conclusively waived its right to purchase the
Property at the Offer Price and Landlord shall have the right within one (1)
year of the Offer Notice to sell the Property at a price (considering the value
of other terms and conditions) which is no less favorable to the purchaser than
a sale of the Property for a cash purchase price equal to 92.5 percent of the
Offer Price on the terms and conditions provided for herein (the "Minimum
Price"); provided, however, that

                  (i) if the Property shall be the Land or the Building, not the
            Land and the Building, than such waiver shall not be applicable to
            the Building or the Land, whichever shall not be the Property, and
            Tenant's rights with respect thereto shall continue in full force
            and effect; and

                  (ii) if Landlord shall desire or propose to sell the Property
            at a price (considering the value of other terms and conditions)
            more favorable to the purchaser than a sale of the Property for a
            cash purchase price equal to the Minimum Price, or shall desire or
            propose to sell the Property after such one (1) year period,
            Landlord shall be obligated to re-offer the Property to Tenant by
            giving to Tenant a new Offer Notice in accordance with Section 37.1
            above and to furnish then current Property Information.


                                       108
   120

Any such new Offer Notice shall be given effect under Section 37.1 except that
if such new Offer Notice shall be given less than 90 days after the initial
Offer Notice the thirty (30) day period referred to in Section 37.1 shall be
shortened to fifteen (15) days from Tenant's receipt of the new Offer Notice and
the then current Property Information.

            37.3 If Tenant provides Tenant's Acceptance to Landlord, Tenant
agrees that it shall concurrently therewith deliver to Landlord a deposit of
five percent of the Offer Price which shall be liquidated damages and,
notwithstanding any other provision of this Lease to the contrary, shall be
Landlord's sole remedy in the case of any default by Tenant under this Article
37 (exclusive of its obligation, having acquired the Property pursuant to this
Article 37, to retain title thereto for one year) or under any obligation to
purchase arising under this Article 37. The closing of such purchase shall be
the first business day which is 60 or more days after the date of Tenant's
Acceptance. Landlord and Tenant agree that closing costs will be paid in
accordance with New York custom.

            37.4 Tenant agrees that it shall not disclose any documents and
information regarding the Property which Tenant's receives under this Article 37
except to those assisting Tenant with the analysis of the Property, or Tenant's
lender, if any, and then only upon making such person aware of the obligations
contained in this Section 37.4 and procuring the agreement of such person to
abide by such obligations. In the event Tenant does not purchase the Property
for any reason whatsoever, Tenant shall return to Landlord, or cause to be
returned to Landlord, all such documents and information.

            Article 38. Tenant's Termination Right.

            Provided that Tenant is not in monetary default under this Lease
beyond any applicable notice or grace period on the date that the Termination
Notice (as defined below) is given, Tenant shall have a one-time option
("Tenant's Termination Option") to terminate this Lease as of the last day of
the calendar month in which shall occur the tenth (10th) anniversary of the day
preceding the Rent Commencement Date of the last to be delivered of the Base
Premises (the "Early Termination Date") with respect to all portions of the
Premises then leased by Tenant other than each Accepted Offer Space leased
pursuant to Article 26 the Scheduled Offer Space Delivery Date of which was
later than the day five (5) years prior to the Early Termination Date (such
excluded portions of the Premises being herein called the "Continuing
Premises")), provided that Tenant shall

                  (i) give irrevocable notice (the "Termination Notice") to
            Landlord of such termination at least eighteen (18) months prior to
            the Early Termination Date, and

                  (ii) pay to Landlord on or before the date thirty (30) days
            prior to the Early Termination Date an amount equal to nine (9)
            times the excess of (a) the monthly Fixed Rent then payable under
            this Lease with respect to the Early Termination Premises (as
            defined below) over (b) the Landlord's


                                       109
   121

            Monthly Payment then payable under this Lease with respect to the
            Early Termination Premises (the "Termination Fee").

            Notwithstanding the foregoing, if Tenant shall fail to pay the
Termination Fee on or before the date that is thirty (30) days prior to the
Early Termination Date or if on the date thirty (30) days prior to the Early
Termination Date Tenant is otherwise in monetary default under this Lease beyond
any applicable notice or grace period then, at the option of Landlord to be
exercised by notice to Tenant given on or before the date twenty (20) days prior
to the Early Termination Date, the Termination Notice shall be ineffective and
Tenant's option to terminate this Lease under this Article 38 shall thereupon
forever terminate.

            Subject to the preceding paragraph, if Tenant shall timely exercise
Tenant's Termination Option and timely pay the Termination Fee then the term of
this Lease with respect to all portions of the Premises other than the
Continuing Premises (the "Early Termination Premises") shall end on the Early
Termination Date with the same force and effect as if such Early Termination
Date were the Expiration Date (and, with respect to the Early Termination
Premises, the parties shall have the same rights and obligations as they would
have had with respect to the Premises upon expiration of this Lease on the
Expiration Date). No such termination shall affect the Continuing Premises and
this Lease shall continue with respect to the Continuing Premises as if Tenant
had not exercised Tenant's Termination Option.

            Tenant's failure to comply with the notice provision above shall be
deemed a waiver of all of Tenant's rights under this Article 38 and Tenant's
option to terminate this Lease with respect to the Early Termination Premises
shall thereupon forever terminate.

            Article 39. Landlord Defaults - Tenant Right to Cure.

            39.1 If

                  (i) Landlord shall fail to perform any of its obligations
            under Article 10,11 or 15,

                  (ii) Landlord shall fail to make any repairs or alterations
            that the Landlord is required to make pursuant to the terms of this
            Lease, or

                  (iii) Landlord shall make any repairs or alterations in or
            about the Premises or the Building, and as a result of such repairs
            or alterations made by Landlord, it becomes impractical for Tenant
            to (and the Tenant does not) conduct its business operations in any
            portion of the Premises in substantially the same manner as
            theretofore conducted

(any or all of the foregoing hereinafter sometimes referred to as a "Landlord
Failure") and, after notice thereof by Tenant to Landlord (a "Notice of Landlord
Failure"), Landlord does


                                       110
   122
not with due diligence commence action promptly (immediately, in the case of
emergency) to remedy such Landlord Failure, or if so commenced, does not remedy
such failure within fifteen (15) days from the date of Tenant's notice or such
longer period as may be provided by the last sentence of this paragraph, then,
provided that at least 50% of the Premises then subject to this Lease shall not
then be subject to any sublease (other than any sublease entered into pursuant
to Section 12.7 or 12.8), Tenant shall have the right (the "Tenant's Self-Help
Right"), upon the giving of five (5) days' written notice to Landlord (or, in
the case of emergency, upon the giving of such notice, oral or written, as may
be reasonable under the circumstances) (the "Tenant's Self-Help Notice"), to
remedy or endeavor to remedy such Landlord Failure and, Landlord shall, within
twenty (20) days after Tenant's submission to Landlord of Tenant's bills
therefor accompanied by copies of the invoices paid by Tenant, reimburse Tenant
for the actual costs incurred by Tenant in so remedying or endeavoring to remedy
such Landlord Failure (plus interest at two percent (2%) above the Prime Rate
from the date(s) such costs were incurred until the date(s) that such costs are
finally reimbursed). Tenant agrees to use due care and good workerlike
procedures in the performance of self-help which affects any portion of the
Building outside of the Premises. With respect to any Landlord Failure the
curing of which requires in excess of fifteen (15) days, if within such fifteen
(15) days Landlord shall commence such cure and notify Tenant that it intends to
prosecute the same to completion, such fifteen (15) day period shall be extended
so long as Landlord is prosecuting such remedy continuously and with all due
diligence.

            Except as provided in the next sentence, any bill rendered by Tenant
shall be deemed valid and due and owing and if not paid within the aforesaid
twenty (20) days Tenant shall have the right to set-off the amount thereof
against the Fixed Rent and Additional Rent payable under this Lease. If, by
notice to Tenant within twenty (20) days after Tenant's submission of any bill
to Landlord, Landlord shall dispute Tenant's entitlement to reimbursement
therefor, in whole or in part, then (i) pending resolution of such dispute
Tenant shall not set-off the amount in dispute, and (ii) if the such dispute is
not settled by the parties within ten (10) days of Landlord's notice of dispute,
the same shall be subject to arbitration in accordance with the provisions of
Article 35. If in arbitration it shall be determined that Tenant was not
entitled to exercise Tenant's Self Help Right, (i) Landlord shall not be require
to make any such reimbursement except to the extent of any costs which by virtue
of Tenant's activities under this Article Landlord shall have avoided, and (ii)
if and to the extent that Tenant shall have removed any repair or alteration it
was not entitled to remove, Tenant shall promptly restore the same.

            Concurrently with Tenant's giving any Notice of Landlord Failure or
Tenant's SelfHelp Notice, Tenant shall give a copy thereof to the holder of any
Underlying Mortgage or the lessor of any Underlying Lease to whom Landlord has
instructed Tenant to give copies (provided that Tenant shall have been furnished
with the then current address of such holder or lessor). Such holder or lessor
shall have the same rights (but only within the same time limits and subject to
the same obligations) as Landlord to remedy the Landlord Failure to which such
notice relates.

            39.2 Landlord's Failure to Pay Costs of Initial Improvements

            (a) If Tenant believes that Landlord has failed timely to pay to the
appropriate party any amount which Landlord is required by Section 4 of the
Initial Improvements Agreement to pay, then (i) Tenant may give Landlord a
notice (a "Section 39.2 Demand Notice") specifying and identifying such amount
(a "Section 39.2 Demand Amount") and containing the following statement in block
capital letters: "THIS NOTICE IS BEING GIVEN UNDER Section 39.2 OF OUR LEASE.
YOUR FAILURE TIMELY TO PAY THE COSTS HEREIN SPECIFIED AND FURNISH EVIDENCE
THEREOF TO TENANT WILL RESULT IN TENANT HAVING THE RIGHT TO PAY SUCH COSTS AND
OFFSET THE AMOUNT SO PAID AGAINST RENT DUE UNDER THE LEASE" and (ii) at any time
on or after the 10th day after the giving of such Section 39.2 Demand Notice
Tenant may pay the Section 39.2 Demand Amount or any portion thereof to the
appropriate party (together with all interest, penalties, late charges and
similar fees thereon or with respect thereto) provided, that if within 10 days
after the giving of the Section 39.2 Demand Notice Landlord notifies Tenant that
Landlord has paid all of such Section 39.2 Demand Amount to the appropriate 
party (together with all interest, penalties, late charges and similar fees 
thereon or with respect thereto) (which notice shall include evidence of such 
payment) and Landlord has actually done so Tenant shall not be entitled to make
payment of the Section 39.2 Demand Amount or any portion thereof and if within 
10 days after the giving of such Section 39.2 Demand Notice Landlord notifies 
Tenant that Landlord has paid a portion identified and specified in such notice
of the Section 39.2 Demand Amount to the appropriate party (together with all 
interest, penalties, late charges and similar fees thereon or with respect 
thereto) (which notice shall include evidence of such payment) and Landlord has
actually done so Tenant may pay only the balance of such Section 39.2 Demand 
Amount not so paid by Landlord or any portion of such balance to the 
appropriate party (together with all interest, penalties, late charges and 
similar fees thereon or with respect thereto). The amount paid by Tenant 
pursuant to this Section 39.2(a) is called an "Section 39.2 Advance").

            (b) If Tenant makes an Section 39.2 Advance in accordance with
Section 39.2(a) then, except as otherwise provided in Section 39.2(c), (i)
Landlord shall reimburse to Tenant within 15 days after Tenant's demand therefor
the amount of the Section 39.2 Advance, together with interest thereon at the
Interest Rate from the date of payment by Tenant to the date on which Landlord
so reimburses Tenant, (ii) if Landlord shall fail timely to make such
reimbursement, Tenant shall have the right to setoff the amount of the Section
39.2 Advance together with such interest thereon against the Rent under this
Lease, and (iii) Landlord shall be deemed to have waived its right to claim that
such setoff was improper or constitutes a failure to pay rent or other default
under this Lease and its right to bring and maintain a separate action against
Tenant to recover all or any portion of the Section 39.2 Demand Amount.

            (c) If within l0 days after the giving of the Section 39.2 Demand
Notice, Landlord notifies Tenant (an "Section 39.2 Dispute Notice") that
Landlord believes that all or a portion identified and specified in such Section
39.2 Dispute Notice of the Section 39.2


                                       112
   124

Demand Amount is not required by Section 4 of the Initial Improvements Agreement
to be paid by Landlord or is not overdue (in either case all or such identified
and specified portion being herein called the "Disputed Section 39.2 Amount"),
then Landlord shall not be required to reimburse Tenant and Tenant shall not
have a right of set-off with respect to the Disputed Section 39.2 Amount except
to the extent that the dispute with respect thereto is resolved in Tenant's
favor in accordance with the next sentence. Tenant shall have the right, with
respect to any such dispute, to elect by notice to Landlord that such dispute be
resolved by litigation or arbitration pursuant to Article 35, but any such
election shall be irrevocable with respect to the dispute in question.

            (d) Each Section 39.2 Advance shall constitute a loan from Tenant to
Landlord and notwithstanding Tenant's having made such Section 39.2 Advance the
Initial Improvements Work to which such Section 39.2 Advance shall relate, shall
nonetheless constitute the property of Landlord, a part of the Premises and
subject to the Lease.

            39.3 Successor Liability Notwithstanding the provisions of Article
31, Tenant's rights under this Article 39 shall survive any transfer of any
interest in the Land and/or the Building and after any thereof shall also be
enforceable against the transferee and its transferees (other than the holder of
any Existing Mortgage), notwithstanding that the obligations or amounts to which
such rights relate were originally required to be performed or paid by the
transferor.

            Article 40. Miscellaneous.

            40.1 If either party shall commence an action or proceeding to
enforce this Lease or any provision thereof, then (except as otherwise
specifically provided elsewhere in this Lease) the prevailing party shall be
reimbursed by the losing party within thirty (30) days after rendering to the
losing party a bill for the reasonable counsel fees and disbursements and court
costs incurred by the prevailing party in such action or proceeding.

            40.2 In the event of a breach or threatened breach on the part of
either party hereunder with respect to any of the covenants, agreements, terms,
provisions or conditions on the part of, or on behalf of, such party to be kept,
observed or performed, the other party shall also have the right of injunction.
The specified remedies to which a party may resort hereunder are cumulative and
are not intended to be exclusive of any other remedies or means of redress to
which a party may lawfully be entitled at any time, and a party may invoke any
remedy allowed at law or in equity as if specific remedies were not provided for
herein.

            40.3 Whenever any right of Tenant provided for in this Lease is
subject to the condition that the area of the Premises not sublet (other than
under Section 12.7 or 12.8) shall then exceed 250,000 rentable square feet (or
other amount) (e.g. Section 7.1(b), 26.5), (or any similar condition) then for
purposes of determining whether such condition is satisfied all of the space
referred to in Exhibit C of this Lease shall be deemed leased to


                                       113
   125

Tenant and included in the Premises on and after the Effective Date of this
Lease, notwithstanding that the Delivery Date may not have commenced with
respect to one or more Applicable Portions.

            40.4 Any reference in this Lease to Tenant not being in default
beyond applicable notice and/or cure periods (or any similar reference) shall
refer to applicable notice and/or cure periods provided for in Article 17.

            40.5 Whenever this Lease requires either party to pay any amount to
the other, if no other time period is specified, such amount shall be due within
ten (10) days of the other party's demand therefor accompanied by any
documentation required by the terms of this Lease. If any amount due to either
party shall not be paid when due, the same shall bear interest at the Interest
Rate from the due date until paid.

            40.6 Whenever, by operation of Article 26 or otherwise, Tenant shall
lease the last usable portion of any Partial Premises Floor such floor shall be
come a Full Premises Floor and there shall be deemed included in the Premises
and leased to Tenant all common and other areas of such floor as shown on the
typical floor plan included in Exhibit B and any other comparable areas not
shown on such plan because of differences between the floor in question and the
typical floor upon which the typical floor plan is based, but the operation of
this Section 40.6 shall not result in any increase in the rentable area of the
Premises.

            40.7 Landlord shall consent to any sublease to Tenant of, or any
assignment to Tenant of any lease covering, any space in the Building proposed
to be made by any tenant of any space in the Building, notwithstanding any
prohibition of such sublease or assignment contained in such other tenant's
lease and notwithstanding any provision of such lease entitling Landlord to
withhold consent.

            40.8 Each party agrees that it shall not refer to the other party
hereto in any press release, publicity, advertisement or other promotional
material relative to the entering into of this Lease or the Building nor shall
it permit any broker representing it to so refer to the other party.

            40.9 The headings of the Articles of this Lease are for convenience
only and are not to be considered in construing the Articles.

            40.10 This Lease may be executed in any number of counterparts, and
each counterpart hereof shall be deemed to be an original instrument, but all
counterparts together shall constitute but one agreement.

            Article 41. ICIP & LMEP Program

            41.1 The Project: the Benefits. The parties agree that, in
connection with any work to be done either by Landlord or Tenant in the Premises
or in the Building in


                                       114
   126
connection with Tenant's use and occupancy of the Premises (all such work,
including any Special Installations installed by Tenant, the "Project"), Tenant
intends to avail itself of, and Landlord shall use commercially reasonable
efforts to permit Tenant to avail itself of, the benefits and entitlements
provided by (x) Section 489-bbbb, Subdivision #5 of the Industrial and
Commercial Incentive Program (together with the regulations and requirements of
Sections 11-256 through 11-267 of the Administrative Code of the City of New
York, authorized by Title 2-D of Article 4 of the New York Real Property Tax Law
and all rules and regulations promulgated thereunder, the "ICIP Program"), and
(y) Section 25-bb(a), Subdivision 1 of the Lower Manhattan Energy Program
(together with the regulations and requirements of Article 2-I of the General
City Law and all rules and regulations promulgated thereunder, the "LMEP
Program"). Landlord agrees to use commercially reasonable efforts to comply with
all applicable provisions of the ICIP Program and the LMEP Program with the goal
that the Building will receive the benefits and entitlements provided by both
the ICIP Program (such benefits, the "ICIP Benefits") and the LMEP Program (such
benefits, the "LMEP Benefits"; the ICIP Benefits and the LMEP Benefits being
herein sometimes collectively referred to as the "ICIP/LMEP Benefits").

            41.2. Requirements to Obtain Benefits. In accordance with the
requirements of the ICIP Program and the LMEP Program, Landlord and Tenant agree
as follows:

            (a) Landlord and Tenant will complete and execute, and Landlord will
file, a preliminary application for the Building (the "Preliminary ICIP
Application") for the ICIP Benefits that may be available in connection with the
Project, as and within the time periods required by the ICIP Program, and prior
to the issuance of a building permit for, or the award of construction contracts
for, or the commencement of, any work comprising part of the Project (the "ICIP
Work").

            (b) Landlord and Tenant will complete and execute, and Landlord will
file, a final application for the Building (the "Final ICIP Application") for
the ICIP Benefits that may be available in connection with the Project, as and
within the time periods required by the ICIP Program.

            (c) Landlord will complete, execute and file an application for the
Building (the "LMEP Application") for the LMEP Benefits that may be available in
connection with the Project, as required by the LMEP Program, concurrently with
or after the filing of the Preliminary ICIP Application and prior to the
issuance of a building permit for, or the award of construction contracts for,
or the commencement of, any ICIP Work.

            (d) Landlord and Tenant will submit any proofs of expenditure,
plans, reports, certificates of continuing use and other submissions that may be
required to qualify for the ICIP/LMEP Benefits that may be available in
connection with the Project (the "ICIP/LMEP Submissions") as and within the time
periods required by the applicable rules and regulations of the City of New York
and as more particularly hereinafter set forth, including without limitation any
ICIP/LMEP Submissions required to be made to the New


                                       115
   127

York City Department of Finance ("DOF"), the New York City Department of
Business Services ("DBS") or the New York City Office of Labor Services ("OLS"),
and will attend any meetings required by DOF, DBS or OLS or any other
governmental agency charged with administration or enforcement of the ICIP
Program or LMEP Program.

            (e) Landlord shall pay the filing fees imposed in connection with
the filing of the ICIP Preliminary and Final Applications and the LMEP
Application, and any filing fees which may be imposed in connection with any
ICIP/LMEP Submissions the obligation for which is imposed on Landlord, and all
costs incurred by Landlord in connection therewith.

            41.3 Requirements in Respect of Contractors. (a) Landlord and Tenant
acknowledge that the ICIP Program imposes certain requirements with respect to
the hiring and training practices, among other matters, of construction
managers, contractors and subcontractors (collectively herein called
"Contractors") engaged to perform work in connection with the Project
Accordingly, in order to reduce the likelihood that actions taken by Contractors
of Landlord or Tenant will cause the Building to fail to qualify for or to lose
the ICIP/LMEP Benefits, Landlord and Tenant, to the extent required by the ICIP
Program, shall use only such Contractors that qualify under the applicable
requirements of the ICIP Program for performance of work comprising part of the
Project.

            (b) (1) To the extent required by the ICIP Program, all of the
Contractors of Landlord and Tenant employed in connection with the Project shall
be contractually required by Landlord or Tenant, as the case may be, to comply
with the provisions of the ICIP Program, including without limitation the OLS
requirements applicable to construction projects benefiting from the ICIP
Program. Such compliance, as of the date hereof, includes without limitation the
following: the submission and approval of Construction Employment Report(s), and
other periodic reports, attendance at a pre-construction conference and other
conferences with representatives of the OLS and adherence to the provisions of
Article 22 of the ICIP Rules and Regulations, the provisions of New York City
Charter Chapter 13-B and the provisions of Executive Order No. 50 (1980) and the
regulations promulgated thereunder. If Landlord or Tenant is notified of any
violation of the ICIP Program by the other party's Contractors, such party shall
promptly advise the other party (the "NonCompliant Party") and send a copy of
such notice to the Non-Compliant Party. The Non-Compliant Party will use
commercially reasonable efforts to have violations by its Contractors cured by
its Contractors, and the Non-Compliant Party (x) will have the right to promptly
take all necessary actions to cure such violations, and (y) shall have the right
to contest the determination of non-compliance and/or issuance of a penalty by
the DOF and/or the OLS. At the Non-Compliant Party's request, the other party
shall cooperate with the Non-Compliant Party in any such contest, provided that
the other party shall incur no expense or liability with respect to such
cooperation, unless the Non-Compliant Party agrees to reimburse the other party
for such costs and indemnify, defend and hold harmless the other party from and
against any such liability.

   128

            (2) At Landlord's request, to the extent required to enable Landlord
to file annual certificates of continuing use as required by the ICIP Program

                                    Exhibit I
                         Building Rules and Regulations

            1. The rights of Tenant in the sidewalks, entrances, corridors,
elevators and escalators of the Building are limited to ingress in and egress
from the Premises for Tenant and its employees, licensees and invitees and
Tenant shall not use or permit the use of said sidewalks, entrances, corridors,
elevators or escalators for any other purpose. Tenant shall not invite to the
Premises or permit the visit thereto by persons in such numbers or under such
conditions as to interfere with the use and enjoyment by others of the
sidewalks, entrances, corridors, elevators, escalators or any other facilities
of the Building. Fire exits and stairways are for emergency use only and they
shall not be used for any other purpose by Tenant, its employees, licensees or
invitees. Landlord shall have the right to regulate the use of and operate the
public portions of the Building as well as portions furnished for the common use
of Tenants in such manner as it deems best for the benefit of Tenants generally.

            2. Outside of ordinary business hours, Landlord may refuse admission
to the Building to any person not having a pass issued or approved by Landlord
or not accompanied by a person presenting such a pass or not properly identified
and may require all persons admitted to or leaving the Building outside of
ordinary business hours to register. Tenant shall be responsible for all persons
for whom a pass shall be issued or approved at the request of Tenant and shall
be liable for all acts of such persons. Anything to the contrary
notwithstanding, any person whose presence in the Building at any time shall, in
the judgment of Landlord be prejudicial to the safety, character, reputation and
interests of the Building or of its tenants may be denied access to the Building
or may be ejected therefrom. In case of emergency, invasion, public excitement
or other commotion Landlord may prohibit all access to the Building during the
continuance of the same, by closing doors or otherwise, for the safety of
Tenants or protection of property in the Building. Landlord may require any
person leaving the Building with any package or other object to exhibit a pass
from the Tenant from whose Premises the package or object is being removed, but
the establishment or enforcement of such requirement shall not impose any
responsibility on Landlord for the protection of Tenant against the removal of
property from the Premises of Tenant.

            3. Except in the case of a shop, no lettering, sign, advertisement,
trademark, emblem, notice or object shall be displayed in or on the windows or
doors, or on the outside of the Premises, or at any point inside the Premises
where the same might be visible outside the Premises (other than from the
elevators on the floors of the Premises) except that, on any divided floor, the
name and/or symbol of Tenant may be displayed on or adjacent to the entrance
door of the Premises and/or in or so as to be visible from the common areas on
such floor, subject to the approval of Landlord as to the locations, size, color
and style of such display (which approval shall not be unreasonably withheld).

   143

            4. No awnings or other projections of any kind over or around the
outside of the windows or entrances of the Premises shall be installed by Tenant
and only such window blinds and shades as are approved or supplied by Landlord
shall be used in the Premises.

            5. Tenant's right to install safes and other objects of excessive
weight in the Premises shall be conditioned upon Tenant's either (i)
distributing the concentrated weight of the safe or other heavy object or (ii)
reinforcing the floor, subject to prior notice to and consent of Landlord, in
either case (which consent shall not unreasonably be withheld). No safe or other
object whose weight exceeds the lawful load for the area upon which it would
stand shall be brought into or kept upon the Premises other than in accordance
with the preceding sentence. If it is necessary to distribute the concentrated
weight of any safe or heavy object or reinforce the floor, the work involved in
such work shall be done by Tenant at its expense in such manner as Landlord
shall approve (such approval not to be unreasonably withheld). No machines,
machinery or electrical or electronic equipment or appliances of any kind shall
be placed or operated so as to disturb other tenants.

            6. No noise, including the playing of any musical instrument, radio
or television which, in the judgment of Landlord, might disturb other tenants in
the Building shall be made or permitted by Tenant. No animal shall be brought on
the Premises, except seeing eye dogs. No dangerous, inflammable, combustible or
explosive object or material shall be brought into or kept in the Building by
Tenant or with the permission of Tenant, except as permitted by law and the
insurance companies insuring the Building or the property therein or except as
is necessary or appropriate for or in connection with Tenant's permitted
activities in the Building. Any cuspidors or containers or receptacles used as
such in the Premises or for garbage or similar refuse shall be emptied, cared
for and cleaned by Tenant.

            7. All entrance doors in the Premises shall be kept locked by Tenant
when the Premises are not in use.
