                          LEASE MODIFICATION AGREEMENT

            THIS LEASE MODIFICATION AGREEMENT (the "Agreement"), dated as of

New York, New York 10022 ("Landlord") and INSTINET CORPORATION, a Delaware
corporation having an office at 757 Third Avenue, New York, New York 10017

                              W I T N E S S E T H:

            WHEREAS, Landlord and Tenant are parties to that certain Lease (the
"Lease") dated as of November 19, 1992, between Landlord and Tenant, relating to
the entire twenty-eighth (28th) and twenty-ninth (29th) floors in the Building;

            WHEREAS, Tenant desires to lease from Landlord and Landlord desires
to lease to Tenant the entire eighteenth (18th) floor of the Building;

            WHEREAS, Landlord and Tenant desire to modify the Lease on the terms
and conditions hereinafter set forth.

            NOW, THEREFORE, in consideration of the premises, and for good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, and for the mutual agreements herein, the Lease is amended as
follows:

            1. All capitalized terms used herein without definition are defined
in the Lease.

            2. There is hereby added to the Premises the entire eighteenth
(18th) floor of the Building (the "Additional Premises"). The rentable square
foot area of the Additional Premises shall be deemed to be 28,000 rentable
square feet.

            3. A. The Additional Premises are leased for a term (the "Additional
Premises Term") which shall commence on August 1, 1993 and shall expire on the
Expiration Date unless the term shall terminate sooner pursuant to any of the
terms of the Lease or pursuant to law.

               B. Tenant acknowledges that the existing lease with "TeleRep"
covering the Additional Premises expires on July 31, 1993. Anything herein to
the contrary notwithstanding, in the event Landlord is unable to deliver all or
any portion of the Additional Premises to Tenant on August 1, 1993 as a result
of Force Majeure or the holding over of the prior tenant, Tenant shall have no
right whatsoever to cancel or terminate this Agreement (unless possession has
not been delivered to Tenant by September 1, 1993, in which event Tenant may, by
notice to Landlord given prior to the earlier of: (1) December 31, 1993 and (2)
the time

<PAGE>   2

possession is tendered to Tenant, cancel Sections 2 through 17 of this Agreement
which Sections shall, in such event be of no force or effect) and subject to the
foregoing this Agreement shall remain in full force and effect and Landlord
shall not be subject to any liability whatsoever for such inability to deliver
possession. Nothing herein shall extend the Expiration Date of the Lease.

               C. Except for Tenant's right to cancel Sections 2 through 17 of
this Agreement as set forth in Paragraph B, Tenant expressly waives any right to
rescind this Agreement or the Lease under Section 223-a of the New York Real
Property Law or under any present or future statute of similar import then in
force and further expressly waives the right to recover any damages, direct or
indirect, which may result from Landlord's failure to deliver possession of the
Additional Premises by September 1, 1993. This Section is intended to constitute
"an express provision to the contrary" within the meaning of said Section 223-a.

            4. A. The Fixed Rent payable under the Lease shall be amended as
follows:

                        (a) For each of the first five (5) years from and after
the date which is five (5) months from the date on which the Additional Premises
is actually delivered to Tenant (the "Additional Premises Rent Commencement
Date") Fixed Rent shall be increased by $767,200, per annum.

                        (b) For each year following the fifth (5th) anniversary
of the Additional Premises Rent Commencement Date until the Expiration Date,
Fixed Rent shall be increased by $879,200, per annum.

            5. Tenant's Share as defined in Article 6 of the Lease shall be
increased by 4.2% from and after the Additional Premises Rent Commencement Date.

            6. Tenant has inspected the Additional Premises and acknowledges
that the Additional Premises is in good order and repair and accepts the
Additional Premises for occupancy (including any mechanical/electrical
equipment, wherever located) in its present condition "AS IS" on the date hereof
except that Landlord shall, during the performance of Tenant's demolition work
in connection with Tenant's initial work in the Additional Premises, remove the
existing internal stairway between the 18th and 19th floors. Tenant shall
perform all work to prepare the Additional Premises for its occupancy in
accordance with the Work Letter. Landlord shall have no obligation to perform
any work in or for the Premises to prepare same for the occupancy by Tenant,
except (i) as above set forth and (ii) that, to the extent that Landlord's
representations in Section 12 are untrue, Landlord shall promptly, at its sole
cost, cure any condition resulting from such misrepresentation. Within a
reasonable period of time after the delivery to Tenant of possession of the
Additional Premises, Landlord shall at its sole cost and expense install
louvered blinds

                                       2
<PAGE>   3

on the atrium glass of the Additional Premises and shall replace any missing
louvered blinds on the peripheral external windows of the Additional Premises
not delivered with the possession thereof.

            7. A. Subject to the rights of Kasowitz Hoff Benson & Torres under
its present Lease with Landlord (the "Kasowitz Lease"), if Tenant is not in
default under the Lease beyond any applicable notice and grace period, provided,
that Tenant has not subleased more than forty percent (40%) of the Premises,
Tenant shall have the option (the " 19th Floor Option") to lease from Landlord
the entire nineteenth (19th) floor (but not part thereof) (the "19th Floor").

                  B. The 19th Floor Option shall be exercisable by notice given
to Landlord no later than ninety (90) days following the Tenant's receipt of
notice from the Landlord that the Kasowitz Lease, as same may have been extended
pursuant to its terms, will expire in not more than one (1) year, but in no
event may Tenant exercise the 19th Floor Option later than March 31, 1997

                  C. If Tenant exercises the 19th Floor Option:

                        (a) Landlord shall deliver possession of the 19th Floor
to Tenant within thirty (30) days following the termination of the Kasowitz
Lease.

                        (b) Fixed Rent, as defined in Article 3 shall be
increased, as of the date of delivery to Tenant of possession of the 19th Floor,
by the greater of $712,400 or the amount determined in accordance with Section 7
(D), below for the period through the fifth (5th) anniversary of the Additional
Premises Rent Commencement Date and thereafter $816,400 or the amount determined
in accordance with Section 7 (D) below. In addition, pursuant to Section 7(C)
(c), Tenant shall also pay Additional Rent for the 19th Floor.

                        (c) Tenant's Share, as defined in Article 6 of the
Lease, shall be increased by 3.9% from and after the date of delivery to Tenant
of possession of the 19th Floor.

                  D. After Tenant has given Landlord notice of the exercise of
the 19th Floor Option, Landlord and Tenant shall seek to agree as to the
additional Fixed Rent for the 19th Floor. If they shall not agree as to such
additional Fixed Rent within thirty (30) days after Tenant exercises the 19th
Floor Option, the fair annual market rental value of the 19th Floor shall be
determined by arbitration in accordance with Section 45.04.

                        (a) If the 19th Floor is delivered to Tenant prior to
the time the additional Fixed Rent therefore has been determined, the annual
Fixed Rent thereafter payable pending such determination, shall be increased by
$712,400 (the "Temporary Rate"). In addition, pursuant to Section 7(C)(c),
Tenant shall also pay Additional Rent for the 19th Floor. Thirty (30) days

                                       3
<PAGE>   4

after the determination of the fair market rental value of the 19th Floor, if
such fair market value, less the then Additional Rent allocable to the 19th
Floor exceeds the Temporary Rate, Tenant shall promptly pay Landlord the
difference for the period since possession was given Tenant; and the increase in
the Fixed Rent shall be thereafter increased to an amount not less than such
fair market rental value less the Additional Rent allocated to the 19th Floor.

                  E. If Tenant exercises the 19th Floor Option, the parties
shall immediately be bound thereby without the execution of an amendment to the
Lease; however, at the request of either party, the parties shall promptly
execute and deliver a written amendment to the Lease reflecting the addition of
the 19th Floor as part of the Premises for the remainder of the Term of the
Lease, the increase of the Fixed Rent and the increases of the Tenant's Share as
provided above, applicable to such 19th Floor. Except for such changes, the
Lease, as amended by this Agreement, shall apply with respect to the 19th Floor
and the 19th Floor shall be and become part of the Premises. Tenant shall accept
possession of the 19th Floor, and the facilities thereto and improvements
therein in the then "AS IS" condition on the date of delivery thereof to Tenant
and Landlord shall not be required to perform any work or to give Tenant any
work allowance with respect to any such space, except that all Building
Equipment serving the 19th Floor shall be in good working order. Notwithstanding
the foregoing, if Landlord is unable to deliver the 19th Floor to Tenant on the
proposed delivery date thereof as a result of Force Majeure or the holding over
of the prior tenant, Landlord shall not be subject to any liability whatsoever
for such failure or inability to deliver possession and the exercise of the 19th
Floor Option shall remain effective (unless possession has not been delivered to
Tenant within five (5) months following the expiration of the Kasowitz Lease, in
which event Tenant may, by notice given to Landlord prior to the earlier of: (1)
9 months after the expiration of the Kasowitz Lease and (2) the time possession
is tendered to Tenant, cancel the 19th Floor Option). Nothing herein shall
operate to extend the Expiration Date for any of the Premises (including but not
limited to the 19th Floor) beyond the date otherwise fixed therefor in the
Lease.

            Time shall be of the essence with respect to the Tenant's exercise
of the 19th Floor Option, and the time period for the exercise of such option
shall not be extended for any reason. If Tenant shall fail to exercise the 19th
Floor Option, Tenant's rights with respect thereto shall wholly cease, terminate
and expire, and Tenant shall upon request of Landlord confirm such nonexercise
in writing, but failure to do so by Tenant shall not operate to revive any
rights of Tenant under this Section.

            Nothing in this Section shall be construed (a) to obligate Landlord
to refuse its consent to any proposed sublease for a term less than the then
remaining term of the Kasowitz Lease or assignment of the Kasowitz Lease by a
tenant in possession of any portion of the 19th Floor; or (b) to obligate
Landlord to evict

                                       4
<PAGE>   5

a tenant of the 19th Floor which is in default under the Kasowitz Lease (but
Landlord shall, at Landlord's cost and expense, commence and prosecute holdover
proceedings against the tenant of the 19th Floor after the Kasowitz Lease has
expired if Tenant has theretofore exercised the 19th Floor Option).

            Except for the Tenant's right to cancel the 19th Floor Option as set
forth above, Tenant expressly waives any right to rescind this Agreement or the
Lease under Section 223-a of the New York Real Property Law or under any present
or future statute of similar import then in force and further expressly waives
the right to recover any damages, direct or indirect, which may result from
Landlord's failure to deliver possession of the 19th Floor on the commencement
date with respect to the 19th Floor. This Section is intended to constitute "an
express provision to the contrary" within the meaning of said Section 223-a.

            8. Section 22.09 of the Lease is amended by changing "14,500" in the
fourth line to "21,750."

            9. Section 31.02 of the Lease is amended by changing "fifty (50)" in
the sixth line to "seventy-five (75)".

            10. Section 15.02 of the Lease shall be amended to deem the total
damage or the rendering wholly untenantable of the Trading Floor to be the
equivalent of a total damage or rendering wholly untenantable of the Premises.
The "Trading Floor" shall be defined as the twenty-ninth (29th) floor so long as
such floor is the principal site of Tenant's trading operations. Tenant shall
promptly notify Landlord if the Trading Floor is moved from the twenty-ninth
(29th) floor.

            11. Landlord covenants that Landlord will modify the elevator cabs
of the Building so that such elevator cabs are in compliance with The Americans
with Disabilities Act.

            12. REPRESENTATIONS AND WARRANTIES. Landlord represents, warrants
and covenants that:

                  (a) The Additional Premises has and will have available upon
delivery of the Additional Premises at least 50 nominal tons of air conditioning

Premises shall be given to Tenant.

                  (b) There are and will be upon delivery of the Additional
Premises two (2) electric closets and risers in the Additional Premises, each of

            14. (a) If Tenant's equipment in the Additional Premises exceeds the
Building's air conditioning capacity, as represented in Section 12 (a), Tenant
shall at Tenant's cost provide any necessary supplemental air conditioning
capacity, and, may at Tenant's expense, vent cooling air from supplemental air
conditioners through louvers in peripheral windows on the easterly side of the
Building at a location to be mutually agreed upon by Landlord and Tenant.

                (b) Landlord shall make available to Tenant a 400 amp switch in
Landlord's electric frame room to supply power to Tenant's existing supplemental
riser to floors 28 and 29, which riser may also be tapped to serve the

            15. Section 3.03 of the Lease is amended by adding "or the

additional four (4) inch conduits between the Additional Premises and the twenty
eighth (28th) floor communications room through Telephone Closet "A", to
accommodate its communication requirements subject only to the capacity of riser
cabinets and conduits. In addition, Tenant shall have the right to install
additional communications risers, subject to availability and Landlord's
approval, not to be unreasonably withheld or delayed.

            16. Section 14.03 of the Lease is amended by adding "in each of the
twenty-eighth/twenty-ninth floor space and the Additional Premises" after
"bathroom shower" on line four.

            17. Lines 10 and 11 of Section 16.02 of the Lease are amended by

<PAGE>   7

                  A. If the letter of credit is required pursuant to Section
22.04 Landlord may draw upon such letter of credit if the Tenant is in default
beyond all applicable notice and cure periods or has not renewed such letter of
credit in accordance with Section 36.01; provided, however, that in addition to
a sight draft in the form set forth in Exhibit G, Landlord shall also present a
statement in substantially the form of (a) or (b) set forth below:

                        (a) "Tenant is in default under the Lease beyond all
            applicable notice and cure periods"; or

                        (b) "Tenant has failed to comply with the provisions of
            Section 36.01 and has not renewed the letter of credit forty-five
            (45) days prior to its expiration date".

                  B. If Tenant delivers the letter of credit pursuant to Section
22.06(c)(i), drawings under such letter of credit shall be permitted as follows:

                  (i) If Tenant is in default under this Lease beyond all
applicable notice and cure periods and subtenant is in possession of the
Premises and is also in default under the sublease, then Landlord may draw upon
the letter of credit by accompanying Landlord's sight draft with the following
statement:

                        "Tenant is in default under the Lease beyond all
                  applicable notice and cure periods and subtenant is in
                  possession of the Premises and is also in default under the
                  sublease beyond all applicable notice and cure periods."

                  (ii) If Tenant is not in default under this Lease beyond all
applicable notice and cure periods, but subtenant is in default under the
sublease, then if

            (x) Tenant provides Landlord with a substitute letter of credit in
            substantially the same form as the existing letter of credit which
            Landlord holds as security, Landlord shall assign its interest as
            beneficiary under the original letter of credit to Tenant. If, after
            the assignment of the original letter of credit, subtenant remains
            in default, Tenant may draw upon the original letter of credit as
            agreed between Tenant and the subtenant pursuant to the sublease. If
            Tenant evicts the subtenant from the Premises, and Tenant is not
            then in default beyond all applicable notice and cure periods under
            this Lease, Landlord shall return the substitute letter of credit to
            Tenant. In the event Tenant draws upon the letter of credit Tenant's
            sight draft must be accompanied by the following statement:

                                       7
<PAGE>   8

                        "Subtenant is in possession of the Premises and is in
                  default under the sublease beyond all applicable notice and
                  cure periods".

            (y) Tenant does not issue a substitute letter of credit pursuant to
            Paragraph B (ii) (x) above, Landlord shall draw upon the letter of
            credit and hold the funds as security against subtenant's default or
            a potential default by Tenant. If Tenant is not then in default at
            the time of the removal of the subtenant from the Premises, upon
            Tenant's request, proceeds of the letter of credit will be applied
            against any sums owing to Tenant by subtenant as a result of its
            default under the sublease. Tenant shall indemnify Landlord for any
            loss, cost or damage, including attorneys' fees and disbursements
            associated with any claim by subtenant which relates to such
            proceeds, provided; however, Tenant shall not have any obligation to
            indemnify Landlord for its gross negligence with respect to any
            loss, cost or damage. If Landlord draws upon the letter of credit
            Landlord's sight draft must be accompanied by the following
            statement:

                        "Subtenant is in possession of the Premises and is in
                  default under the sublease beyond all applicable notice and
                  cure periods."

                  (iii) If the letter of credit has not been renewed forty-five
(45) days prior to its expiration, then Landlord may draw upon the letter of
credit and hold the proceeds as security against any potential defaults by
Tenant or the subtenant, as the case may be. Tenant shall indemnify Landlord for
any loss, cost or damage, including attorneys' fees and disbursements,
associated with any claim by subtenant which relates to such proceeds, provided;
however, Tenant shall not have any obligation to indemnify Landlord for its
gross negligence with respect to any loss, cost or damage associated with
holding such funds. To draw upon the letter of credit Landlord must accompany
the sight draft with the following statement:

                        "Subtenant has the right to possession of the Premises
                  and the letter of credit has not been renewed in accordance
                  with the terms of the sublease and the Lease forty-five (45)
                  days prior to its expiration date."

                  C. If Tenant delivers a letter of credit in accordance with
Section 22.10.1, Landlord may draw upon the letter of credit if the Tenant is in
default beyond all applicable notice and cure periods or has not renewed the
letter of credit in accordance with Article 36; provided, however, that in
addition to

                                       8
<PAGE>   9

a sight draft Landlord shall present a statement in either the form of (a) or
(b) set forth below:

                        (a) "Tenant is in default under the Lease beyond all
                  applicable notice and cure periods;" or

                        (b) "Tenant has failed to comply with the provisions of
                  Article 36 of the Lease and has not renewed the letter of
                  credit forty-five (45) days prior to its expiration date."

                  D. Notwithstanding anything contained in the Lease, if
subtenant is not in default under the sublease and the subtenancy terminates and
subtenant vacates the Premises, Landlord shall return to Tenant any letter of
credit issued pursuant to Article 22 (provided Landlord has not drawn on such
letter of credit) and Tenant shall have no continuing liability related thereto.
However, in the event subtenant is in default under the sublease upon the
termination of its subtenancy, Landlord may draw upon the letter of credit as
set forth in this Lease.

            Each letter of credit issued pursuant to Article 22 shall operate as
a separate and distinct instrument and may be drawn upon individually in
accordance with this Lease.

            19. Tenant represents that in the negotiation of this Agreement it
dealt with no broker(s) other than The Peregrine White Company, Inc. (the
"Broker") and no other broker participated in bringing about this Agreement.
Tenant hereby indemnifies and agrees to defend and hold Landlord harmless
against any claim or liability arising out of any inaccuracy or alleged
inaccuracy of the above representation. The parties hereto acknowledge that the
Broker will be paid a commission in accordance with a separate agreement.
Landlord represents that to the best of Landlord's knowledge, it has not dealt
with any broker other than the Broker in connection with this Agreement.

            20. This Agreement shall not be effective unless the consent of John
Hancock Life Insurance Company ("Hancock") to this Agreement has been obtained
and a new nondisturbance agreement in the form annexed as Exhibit A is delivered
to Tenant. Landlord shall, within thirty (30) days after the execution and
delivery of this Agreement by Landlord and Tenant, obtain any required consent
and the new nondisturbance agreement from Hancock. If Hancock does not grant
such required consent and deliver the new nondisturbance agreement within said
thirty (30) day period, then Tenant shall have the right to cancel this
Agreement by written notice to Landlord and upon such notice (provided Hancock
shall not have therefore consented to this Agreement and executed and delivered
to Tenant the new nondisturbance agreement) this Agreement shall be of no force
or effect and the Lease shall remain in full force and effect. If Hancock does
not grant any required consent and deliver the new nondisturbance agreement
within sixty (60) days after the

                                       9
<PAGE>   10

execution and delivery of this Agreement by Landlord and Tenant, then Landlord
shall have the right to cancel this Agreement by notice to Tenant, and upon such
notice (provided Hancock shall not have therefore consented to this Agreement
and delivered to Tenant the new nondisturbance agreement) and this Agreement
shall be of no force and effect and the Lease shall remain in full force and
effect.

            21. Except as modified by this Agreement, the Lease shall remain in
full force and effect in accordance with its terms and is hereby ratified and
confirmed.

            22. This Agreement shall be binding on and shall inure to the

any time on ninety (90) days notice to Tenant, install and maintain a mail
conveyor through the Additional Premises in the area marked by cross hatching on

            3. Section 2.01 of the Lease is hereby modified by deleting the date

            4. Section 3.01 of the Lease is hereby modified so that the Fixed
Rent payable under the Lease is increased as follows:

                  A. From and after January 1, 1995 until July 31, 1999, the

            6.Tenant has inspected the Additional 27th Floor Premises and
acknowledges that the Additional 27th Floor Premises is in good order and repair
and accepts the Additional 27th Floor Premises for occupancy (including any
mechanical/electrical equipment, wherever located) in its present condition "AS
IS" on the date hereof, except as hereinafter provided, except that Landlord
shall, in accordance with Exhibit B annexed hereto, in lieu of performing any
work with respect to the Additional 27th Floor Premises, provide a Tenants Work
Allowance (as defined in Exhibit B) of $435,000. Tenant acknowledges that on the
Additional 27th Floor Premises sheet rock now covers the windows over the
atrium. Tenant agrees that during the Term it shall maintain said sheet rock and
said windows. Tenant expressly waives any right to rescind this Lease under
Section 223-a of the New York Real Property Law or under any present or future
statute of similar import then in force and further expressly waives the right
to recover any damages, direct or indirect, which may result from Landlord's
failure to be able to deliver possession of the Additional 27th Floor Premises
prior to the commencement date of the First Renewal Term (hereinafter defined)
should it make the Removal Election (hereinafter defined) with respect to the
Additional 27th Floor Premises. Tenant agrees that the foregoing provision is
intended to

                                      -4-
<PAGE>   6

constitute "an express provision to the contrary" within the meaning of said
Section 223-a. Any such failure shall not extend the Expiration Date.
Notwithstanding the foregoing, if Landlord has made the Removal Election and
such failure is not the result of Force Majeure, Tenant may, not earlier than
sixty (60) days after the date hereof, elect to cancel this Lease, but only with
respect to such Additional 27th Floor Premises, provided, however, such election
to cancel shall not be effective if prior thereto Landlord, having made the
Removal Election, has completed its Removal Work (hereinafter defined). For
purposes of computing the sixty (60) day period referred to above, the Removal
Period (hereinafter defined) shall not be included in such computation.

            7. A. Pursuant to Section 7 of the First Lease Modification
Agreement, Tenant was granted the 19th Floor Option. Notwithstanding the
provisions of said Section 7, but subject to the provisions of paragraph A of
said Section 7 including, without limitation, the rights of the tenant under the
Kasowitz Lease, Tenant hereby exercises the 19th Floor Option. Landlord
acknowledges that, subject to the foregoing, Tenant has validly exercised the
19th Floor Option.

                  B. Landlord and Tenant agree that the First Lease Amendment is
modified as follows:

                        (i) By deleting subparagraph (b) from paragraph C of
Section 7 thereof and replacing it with the following:

                              "(b) Fixed Rent, as defined in Article 3 shall be
increased, as of the date of delivery to Tenant of possession of the 19th Floor,
by $712,400 for the period through July 31, 1998 and from August 1, 1998 by an
additional $104,000. In addition, pursuant to Section 7(C) (c) below, Tenant
shall also pay Additional Rent for the 19th Floor."

                        (ii) By adding to paragraph C of Section 7 thereof a new
subparagraph (d) to read as follows:

                              "(d) The term of the lease of the 19th Floor shall
commence on the date Vacant Possession (hereinafter defined) of the 19th Floor
is tendered to Tenant and shall end on the Expiration Date. Landlord shall
tender Vacant Possession of the 19th Floor to Tenant within thirty (30) days
following the obtaining thereof by Landlord from the tenant under the Kasowitz
Lease, or otherwise."

                                      -6-
<PAGE>   8

                              (iii) By deleting paragraph D from Section 7 and
replacing it with the following:

                              "D. Landlord shall not enter into any amendment or
modification of the Kasowitz Lease to extend the term thereof beyond the stated
expiration date (after giving effect to any existing renewal rights) or grant
any additional renewal rights to the tenant under the Kasowitz Lease."

            8. The Lease is further modified as follows:

                  A. By modifying Article 10 (IMPROVEMENTS; TENANT'S PROPERTY)
as follows:

                        1. By adding to Section 10.01 the following sentences:
"Landlord agrees Tenant may, in accordance with and subject to the provisions of
this Article 10, install, as an Improvement, a stairway between any two (2)
contiguous floors which constitute part of the Premises. Upon the termination of
this Lease before July 31, 2003, Landlord may send to Tenant a Stairway
Reimbursement Notice (hereinafter defined). Unless Tenant has validly exercised
its First Renewal Term Option by a First Renewal Term Election Notice or a
Conditional First

                                      -7-
<PAGE>   9

Renewal Term Election Notice that has become unconditional, Landlord may, at any
time after September 1, 2001 and before January 31, 2003, send to Tenant a
Stairway Removal Notice (hereinafter defined). Tenant shall, within ten (10)
days after receipt by Tenant of the Stairway Removal Notice, notify Landlord
whether it elects (a) to remove, at its sole cost and expense, any such stairway
so constructed and restore both such floors to the condition of such floors
existing prior to the installation of such stairway or (b) to reimburse the
Landlord for the reasonable cost incurred by landlord for such removal and
restoration; provided, however, the foregoing obligation to remove, restore or
reimburse shall not apply to the stairway between the 18th and 19th floors or to
any other such stairway if such Expiration Date or termination occurs during the
First Renewal Term or the Second Renewal Term. As used herein, the term
"Stairway Removal Notice" shall be a notice from the Landlord directing that
Tenant elect to comply with either clause (a) or clause (b) of this subparagraph
1. As used herein, the term "Stairway Reimbursement Notice" shall mean a notice
from Landlord to Tenant demanding that Tenant comply with the provisions of
clause (b) of this subparagraph 1. Upon the sending of a Stairway Reimbursement
Notice Tenant shall be required, after the

                                      -8-
<PAGE>   10

Expiration Date, to comply with the reimbursement obligations of said clause (b)
of this subparagraph."

                        2. By adding to Section 10.10 of the lease "or at
Additional 27th Floor Premises" after the word "Premises" on line 4 of said
section.

                  B. By modifying subparagraph B of Section 12.04 of the Lease
as follows:

                        1. By inserting the number "(1)" before the word
"Landlord" in the first line of said subparagraph B.

                        2. By adding a new subparagraph (2) to read as follows:

            "(2) (a) Subsequent to the date hereof, Tenant will provide Landlord
with a comprehensive roof-top plan (the "Roof-Top Plan"), drawn by Flack and
Kurtz, onto which Tenant will draw all equipment, machinery, wiring, support
apparatus, structures and other ancillary materials which Tenant wishes to place
on the roof of the Building and which will be used by Tenant in the day-to-day
conduct of its business. The Roof-Top Plan must also show all other

                                      -9-
<PAGE>   11

equipment now located on the roof. Landlord and Landlord's engineer(s) will
review such Roof-Top Plan. Provided the Roof-Top Plan and the implementation
thereof in accordance therewith does not violate the Certificate of Occupancy,
temporary or permanent, for the Building and further provided that, in
Landlord's reasonable judgement, the Roof-Top Plan and the implementation
thereof in accordance therewith does not interfere with the proper and efficient
functioning of the Building or Building Equipment or the pre-existing equipment
of any other tenant, Landlord will not unreasonably withhold or delay its
approval of the installation of such equipment as shown and specified on such
Roof-Top Plan."

            "(b) Tenant shall pay for any and all costs associated with the
installation, operation and maintenance of such Roof-Top Plan or its
implementation, including the reasonable cost of Landlord's engineer(s) and the
cost of any structural changes or reinforcing necessitated by the proposed
installations and comply, in all respects, with the provisions of subparagraph
B(l) of this Section 12.04. Tenant shall not be required to pay any rent with
respect to the rights granted to Tenant under this subparagraph (2). Landlord's
approval of Tenant's proposed installation (as shown by the Roof-Top Plan) is
not a waiver under this Lease

                                      -10-
<PAGE>   12

of Tenant's obligation to comply with each of the Legal Requirements."

                  C. By deleting the 17th and 18th lines of Section 13.03 of the
Lease and replacing them by the following: "under Article 43 (EXTENSION OPTION)
or under Article 46 (LIMITED EXPANSION OPTION), then in any such event".

                  D. By modifying Section 16.02 of the Lease by substituting the
words beginning with "(amortized over" on line 6 through the words "in excess of
Five Million Four Hundred Sixty Thousand Dollars ($5,460,000)" on lines 10 and
11 with the words" "of the out-of-pocket hard costs actually expended by Tenant
to install Improvements and other changes to the Premises in connection with its
occupancy as follows: (i) with respect to Tenant's occupancy of the Eighteenth
(18th), Twenty-Eighth (28th) and Twenty-Ninth (29th) floors, up to, but not in
excess of Five Million Four Hundred Sixty Thousand Dollars ($5,460,000),
amortized over the initial ten (10) year Term of the Lease and (ii) with respect
to the nineteenth (19th) floor and any and all Expansion Space (hereinafter
defined) set forth in an Expansion Election Notice (hereinafter defined) an
amount not in excess of the out-of-pocket hard costs actually

                                      -11-
<PAGE>   13

expended by Tenant to install Improvements and other changes (amortized over a
ten (10) year period commencing on the first day of the term of the lease of the
19th Floor, with respect to the 19th Floor, and on the first day of the
Expansion Term with respect to the Expansion Space).

                  E. By modifying Section 22.04 of the Lease by (1) deleting
from line 41 of such Section the word "Tenant" and inserting ", provided such
successor corporation executes, acknowledges and delivers to Landlord an
agreement in writing expressly assuming and agreeing to be bound by all of the
terms, conditions and provisions of this Lease and has complied with all of the
other provisions of this Section 22.04, assignor" and (2) adding the following
sentences at the end of such section. "Notwithstanding its failure, as Tenant,
to comply with only condition (B) of Section 43.01 or Section 46.01, as the case
may be, a successor corporation shall be afforded the rights of Tenant under
Articles 43 (EXTENSION OPTION) and 46 (LIMITED EXPANSION OPTION) provided that
at the time of the sending of the First Renewal Term Election Notice or
Conditional First Renewal Term Election Notice or First 28 and 29 Renewal Term
Election Notice under Article 43 (EXTENSION OPTION) or its Expansion Election
Notice under Article 46 (LIMITED EXPANSION OPTION), as the case may be, such
successor corporation

                                      -12-

either (1) has a Standard and Poors rating of BBB or better and a Moody's rating
of Baa or better (unless such successor corporation is rated by only one (1)
such service, in which event it has such rating of such service) or (2) has a
net worth of not less than the $100 million, as shown on its most recent audited
financial statement provided, however, that such audited financial statement is
for a calendar year or fiscal year ending not more than eighteen (18) months
prior to the time of the sending of such First Renewal Term Election Notice or
Conditional First Renewal Term Election Notice or First 28 and 29 Renewal Term
Election Notice under Article 43 (EXTENSION OPTION) or its Expansion Election
Notice under Article 46 (LIMITED EXPANSION OPTION), as the case may be, (which
financial statement shall be prepared in accordance with generally accepted
accounting principles by one of the so-called "big eight (8)" accounting firms
or such other nationally or regionally recognized accounting firms as may be
approved by Landlord, such approval not to be unreasonably withheld) and, in
either case, provide Landlord with a true copy of such ratings or such audited
financial statement, as the case may be, and provided further, however, if the
audited financial statement submitted by Tenant is not of its most recently
completed calendar year or fiscal year, Tenant shall, promptly after the
preparation of such audited financial statement for its

                                      -13-
<PAGE>   15

most recently completed calendar year or fiscal year, but not later than one
hundred twenty (120) days after the completion of such calendar year or fiscal
year, deliver a copy thereof (the "Recent Audited Statement") to Landlord (and
if such Recent Audited Statement discloses a net worth of less than $100
million, Tenant shall, within thirty (30) days after the delivery of such Recent
Audited Statement, comply with the provisions of clause (3) hereinafter set
forth, irrespective of the net worth shown on any other financial statement
submitted by Tenant) or (3) if neither of the foregoing tests is met, provide
Landlord, in accordance with and subject to the provisions of Section 36.01A and
36.01B, a one (1) year irrevocable, unconditional Credit (as defined in Section
36.01A) in an amount equal to the aggregate of all Fixed Rent and all Additional
Rent due pursuant to the Lease for the previous fifteen (15) months of the
Lease, which Credit shall comply with the provisions of Sections 36.01A and
36.01B of the Lease and shall otherwise be in form and content reasonably
satisfactory to Landlord. Tenant shall, with respect to such Credit, comply with
its obligations pursuant to the provisions of said Sections 36.01A and 36.01B
and shall maintain such Credit in such amount during the balance of the Term of
the Lease including, if applicable, the First Renewal Term and the Second
Renewal Term; provided, however, that so long as

                                      -14-
<PAGE>   16

Tenant is not in default under the Lease beyond any notice and applicable grace
period, on the first day of each of the last twelve (12) months prior to the
Expiration Date, the required Credit shall be reduced by one-twelfth (1/12) of
the Credit, except that in the last month prior to the Expiration Date, the
required Credit shall be reduced to $100,000, which $100,000 Credit shall be

except as hereinafter provided, may elect by notice to Landlord ("Renewal

Tenant to Landlord, Landlord and Tenant shall, in order to determine the Fixed
Rent per rentable square foot for the First Renewal Premises during the First
Renewal Term, seek to agree as to the amount of the fair annual market rental
value per rentable square foot for the First Renewal Premises. If they shall not
agree as to such

                                      -23-
<PAGE>   25

value by the date which is thirty (30) days after Tenant gives to Landlord the
First Renewal Term Election Notice, then and in such event said annual fair

arbitration" pursuant to Article 28 (ARBITRATION) and as hereinafter in this
Article provided.

            C. Tenant shall not be in default under any of the terms, covenants
and conditions of this Lease beyond any notice and grace period hereunder at the
time Tenant gives the First Renewal Term Election Notice or the Conditional
First Renewal Term Election Notice, as the case may be, to Landlord.

per rentable square foot for the First Renewal Premises payable as of July 31,
2003, the last day of the initial Term and (ii) the sum (per rentable square
foot for

                                      -24-

of the Fixed Rent payable for the First Renewal Premises during the First
Renewal Term in accordance with the foregoing provisions of this Article shall
not have been determined, then, pending such determination, Tenant shall pay
Fixed Rent for the First Renewal Premises at 125% of the Fixed Rent per rentable
square foot for the First Renewal Premises payable hereunder as of the last day
of the initial Term (the "First Temporary Rate"). After the determination by
appraisal of the annual fair market rental value per rentable square foot for
the First Renewal Premises, if such value is greater or lesser than the First
Temporary Rate, Tenant shall promptly pay to Landlord or Landlord shall pay to
Tenant, as the case may be, the difference between the rent theretofore paid at
the First Temporary Rate and the rental value per rentable square foot
determined by the appraisal; and the Fixed Rent for the First Renewal Premises
so determined by the appraisal shall, except as otherwise provided, be payable

Term, Landlord and Tenant shall execute, acknowledge and deliver to each other
an agreement specifying the amount of the Fixed Rent for the First Renewal
Premises for such First Renewal Term (but any failure to execute such an
agreement shall not affect Tenant's obligation to pay and Landlord's right to
receive such Fixed Rent).

            Section 43.04. If Landlord and Tenant shall be unable to agree as to
the annual fair market rental value per rentable square foot within said thirty
(30) day period, then and in such event said annual fair market rental value per
rentable square foot for the First Renewal Premises shall be determined by
"baseball arbitration" pursuant to Article 28 of the Lease (ARBITRATION) and as
hereinafter provided.

sending of the Second Renewal Term Election Notice (hereinafter defined) Tenant
meets either of the following conditions: (A) Tenant, and all related

five (5) years commencing on August 1, 2008 and ending on July 31, 2013 (the
"Second Renewal Term"), upon the same terms and conditions as contained in this

following terms and conditions:

            A. Written notice of such election (the "Second Renewal Term

hereinafter provided.

            The arbitrator shall be a licensed real estate broker doing business
in the Borough of Manhattan, City and State of New York, and having not less

between Debevoise & Plimpton and Landlord, as the same may be amended or
modified from time to time after the date hereof by Landlord and the tenant
under such lease (such lease, as it may be so amended or modified is called the
"Debevoise & Plimpton Lease"). Nothing contained in this Agreement or in the

Availability Notice, or the sending by Tenant of an Expansion Election Notice
in response to the Landlord Expansion Space Availability Notice, or the sending
of a First 28 and 29 Renewal Term Election Notice (hereinafter defined) shall be
construed (1) to grant any renewal or extension rights to Tenant with respect to
the 28 and 29 Renewal Premises unless and until a Landlord 28 and 29
Availability Notice is required to be sent to Tenant, Tenant expressly
acknowledging that Landlord is under no duty to cause the tenant of the
Debevoise & Plimpton Lease to surrender to Landlord, or waive, all or any of its
rights to the 28 and 29 Renewal Premises and that Landlord may never be required
to or be able to send a Landlord 28 and 29 Availability Notice, and that
Landlord may, if it so elects in its sole discretion, actively deal in any
manner with the tenant under the Debevoise & Plimpton Lease in such a manner as
may prevent such tenant from surrendering or waiving (or in such manner as may
induce such tenant not ever to surrender or waive) all of its rights to the 28
and 29 Renewal Premises to Landlord, (2) to prevent Landlord from negotiating
with the tenant under the Debevoise & Plimpton Lease or from entering into one
or more modifications of the Debevoise & Plimpton Lease, which modification or
modifications may contain modifications to the rental or other provisions
thereof or grant renewal or extension

which may extend past the Term of this Lease as it may be extended, (3) to
obligate Landlord to (a) refuse its consent to any proposed sublease or
assignment by the tenant under the Debevoise & Plimpton Lease of all or any
portion of the premises demised thereunder or the 28 and 29 Renewal Premises,
(b) accept a surrender by the tenant of the Debevoise & Plimpton Lease of its
rights with respect to the 28 and 29 Renewal Premises or (c) agree with the
tenant under the Debevoise & Plimpton Lease to cancel or modify the rights of
such tenant with respect to such 28 and 29 Renewal Premises or (4) to obligate
Landlord to evict the tenant under the Debevoise & Plimpton Lease if in default
thereunder, even if the effect of any such action or inaction described in
clauses (1) to (4) inclusive, considered singly or cumulatively, may be to
preclude the tenant of the 28 and 29 Renewal Premises from ever surrendering or
waiving (or to induce such tenant not ever to surrender or waive) all of its
rights to the 28 and 29 Renewal Premises or may otherwise materially and
adversely affect the possibility of tendering of Vacant Possession of the 28 and
29 Renewal Premises to Tenant.

            B. Anything herein contained to the contrary notwithstanding,
Tenant's renewal option with respect to the

                                      -36-
<PAGE>   38

28 and 29 Renewal Premises is conditioned upon and is subject and subordinate
to (1) the provisions of paragraph A of this Section and (2) the tenant under
the Debevoise & Plimpton Lease surrendering to Landlord or waiving all of its
rights to the 28 and 29 Renewal Premises or such tenant failing to elect to rent
such 28 and 29 Renewal Premises pursuant to its rights under the Debevoise &
Plimpton Lease. Tenant hereby acknowledges that the tenant under the Debevoise &
Plimpton Lease has such prior right to rent the 28 and 29 Renewal Premises
beginning August 1, 2003 and that Tenant has no right under this Article 43 or
any other provision of this Agreement or the Lease with respect to the 28 and 29
Renewal Premises unless and until the tenant under the Debevoise & Plimpton
Lease fails to so rent the 28 and 29 Renewal Premises whether pursuant to such
right or on other terms and conditions that may, after the date hereof, be
negotiated by Landlord and the tenant under the Debevoise & Plimpton Lease.
Promptly after Landlord and the tenant under the Debevoise & Plimpton lease
unconditionally and irrevocably agree to the waiver by such tenant or its
surrender to Landlord of all of its rights to the 28 and 29 Renewal Premises
with respect to the First Renewal Term and the Second Renewal Term, Landlord
will notify Tenant thereof pursuant to a Landlord 28 and 29 Availability Notice;
provided, however, subject to the provisions of paragraph C

                                      -37-

<PAGE>   39

of this Section 43.09, Landlord shall not be required to give Tenant a Landlord
28 and 29 Availability Notice after July 31, 2003.

            C. Written notice of the election to renew the Lease with respect to
the 28 and 29 Renewal Premises (the "First 28 and 29 Renewal Term Election
Notice") shall be given by Tenant to Landlord within thirty (30) days (with time
of the essence) after Landlord sends written notice ("Landlord 28 and 29
Availability Notice") to Tenant of the date (other than the stated expiration
date of the Debevoise & Plimpton Lease) on which the Landlord reasonably
believes the tenant of the 28 and 29 Renewal Premises will surrender all of its
rights to the 28 and 29 Renewal Premises to Landlord with respect to the First
Renewal Term and the Second Renewal Term; provided, however, such First 28 and
29 Renewal Term Election Notice shall not be effective unless either (1) Tenant
has previously sent either (a) a valid First Renewal Term Election Notice or (b)
a valid (i) Conditional First Renewal Term Election Notice with respect to all
other First Renewal Premises and (ii) Renewal Termination Notice electing to
withdraw the Renewal Condition or (2) concurrently with the sending of the First
28 and 29 Renewal Term Election Notice Tenant sends either (a) a valid First
Renewal Term Election Notice or (b) a

                                      -38-
<PAGE>   40

valid (i) Conditional First Renewal Term Election Notice with respect to all
other First Renewal Premises and (ii) Renewal Termination Notice electing to
withdraw the Renewal Condition. The First 28 and 29 Renewal Term Election Notice
shall state that the Tenant hereby elects to extend and renew the Term of the
Lease for all of the First Renewal Term for all of the 28 and 29 Renewal
Premises pursuant to Article 43 of the Lease and may, if the conditions of
Section 46.07 have been met, set forth the election permitted thereunder. Time
shall be of the essence for the sending of the First 28 and 29 Renewal Term
Election Notice.

            D. Upon the giving of the First 28 and 29 Renewal Term Election
Notice, for all purposes of Section 43.01 to 43.04 inclusive (1) the First 28
and 29 Renewal Term Election Notice and the 28 and 29 Renewal Premises shall be
deemed, respectively, a First Renewal Term Election Notice (with respect to the
28 and 29 Renewal Premises) and part of the First Renewal Premises, and (2)
Sections 43.01 to 43.04 inclusive shall be so applied thereto.

            E. The commencement date of the First Renewal Term with respect to
the 28 and 29 Renewal Premises shall be August 1, 2003, and the Expiration Date
of the First Renewal Term shall be July 31, 2008.

            Section 43.10. In the event that the rentable square feet of the
First Renewal Premises set forth in the First Renewal Term Election Notice
exceeds 182,500 rentable square feet, Article 43 shall, if Tenant so elects
concurrently with the first to occur of (a) the sending of its First Renewal
Term Election Notice, or (b) the sending of its Renewal Termination Notice
electing to withdraw the Renewal Condition, be deemed modified as follows:

            A. By modifying Section 43.01 (i) to delete (a) from the 44th line
thereof the words "five (5) years" and replace these words with "ten (10)
years", (b) from the 45th line thereof the year "2008" and replace it with the
year "2013" and (c) from clause (iv) the words "except the Second Renewal Option
set forth in Section 43.05" and (ii) to put a period after the word "Premises"
in said clause (iv).

            B. By modifying paragraph A of Section 43.02 and paragraph E of
Section 43.09 by deleting the year "2008" and replacing it with the year "2013".

            C. By deleting Sections 43.05 to 43.08 inclusive.

                                      -40-
<PAGE>   42

            Section 43.11. Upon the occurrence of either of the events set forth
in clause (a) or (b) of Section 43.02A(5), with respect to the First Renewal
Premises the parties shall immediately be bound thereby without the execution of
an amendment to this Lease; however, at the request of either party, the parties
shall promptly execute and deliver a written amendment to this Lease reflecting
the addition of such S & A Expansion Space as part of the Premises for the First
Renewal Term, the increase of the Tenant's Share by reason of the addition of
such S & A Expansion Space and such other changes resulting from the occurrence
of either of such events. Except for such changes, the provisions of this Lease
shall apply with respect to such S & A Expansion Space. Notwithstanding the
foregoing, in the event Landlord fails or is unable to tender all or any portion
of such S & A Expansion Space to Tenant on the proposed delivery date thereof as
a result of Force Majeure, the performance by Landlord of Removal Work or the
holding over of the prior tenant or otherwise, Landlord shall not be subject to
any liability whatsoever for such failure or inability to tender Vacant
Possession during the continuation of the Force Majeure, holding over by such
prior tenant or performance of such Removal Work, but the Fixed Rent and
Additional Rent shall not commence with respect to such portion of such S & A
Expansion Space

                                      -41-
<PAGE>   43

until the date on which Vacant Possession thereof is actually tendered to
Tenant. Notwithstanding the foregoing, if Vacant Possession of any S & A
Expansion Space included in such First Renewal Premises is not tendered by
Landlord within twelve (12) months following the stated expiration date of the
existing lease of such S & A Expansion Space, Tenant may, by notice given to
Landlord after such twelve (12) month period has expired but prior to the date
Vacant Possession is tendered to Tenant, elect to cancel its First Renewal Term
Election Notice or Conditional First Renewal Term Election Notice, as the case
may be, but only with respect to such S & A Expansion Space as to which such
Vacant Possession has not been tendered. For purposes of computing the twelve
(12) month period referred to above, the Removal Period shall not be included in
such computation. Nothing herein shall operate to extend the Expiration Date for
any of the Premises (including but not limited to such Expansion Space) beyond
the date otherwise fixed for the expiration of the Term or of the First Renewal
Term, as applicable.

            Section 43.12. In addition to the limitation of liability set forth
in Section 43.11, Tenant expressly waives any right to rescind this Lease under
Section 223-a of the New York Real Property Law or under any present or

                                      -42-
<PAGE>   44

future statute of similar import then in force and further expressly waives the
right to recover any damages, direct or indirect, which may result from
Landlord's failure to deliver Vacant Possession of any S & A Expansion Space on
the commencement date of the First Renewal Term. Tenant agrees that the
provisions of this Article are intended to constitute "an express provision to
the contrary" within the meaning of said Section 223-a. Any such failure to so
deliver Vacant Possession shall not extend the Expiration Date of the First
Renewal Term. Notwithstanding the foregoing provisions of this Section 43.12, in
the event that the failure to deliver Vacant Possession of any S & A Expansion
Space on the commencement date of the First Renewal Term is not the result of
Force Majeure, the holding over of the prior tenant or the performance of
Removal Work, Tenant may, not earlier than sixty (60) days after the
commencement date of the First Renewal Term, elect to cancel its First Renewal
Term Election Notice or Conditional First Renewal Term Election Notice, as the
case may be, but only with respect to such S & A Expansion Space with respect to
which Vacant Possession was not so delivered; provided however, such election to
cancel shall not be effective if prior thereto Landlord has tendered Vacant
Possession of such S & A Expansion Space to Tenant. For purposes of

                                      -43-
<PAGE>   45

computing the sixty (60) day period referred to above, the Removal Period shall
not be included in such computation.

            10. Article 44 of the Lease (LIMITED RENEWAL OPTION) is hereby
deleted.

            11. Articles 45 (LIMITED EXPANSION OPTION), 46 (THIRD FLOOR OPTION
OF LIMITED RIGHT OF FIRST REFUSAL) and 47 (RIGHT OF FIRST OFFERING) of the Lease
are hereby deleted and replaced by the following:

                                   ARTICLE 46
                            Limited Expansion Option

            Section 46.01. Subject to the rights of the tenant under the
Debevoise & Plimpton Lease with respect to the D & P Expansion Space
(hereinafter defined) and the rights of the tenant under the existing lease
between Sidley & Austin and Landlord, as the same may be amended or modified
from time to time after the date hereof by landlord and the tenant under such
lease, except as such right to amend or modify said lease with Sidley & Austin
is limited by Section 46.06, (such lease, as it may be so amended or modified,
is called the "Sidley & Austin Lease") with respect to the S & A Expansion Space
if, during the Term of

                                      -44-
<PAGE>   46

the Lease, Tenant is not in default under the Lease beyond any applicable notice
and grace period, and provided (A) Tenant, and all related corporations (as
defined in Section 22.03 of the Lease), which are a permitted sublessee or
sub-sublessee of the Premises and have continuously qualified as a related
corporation, have not subleased, in the aggregate, more than forty percent (40%)
of the entire Premises to one or more corporations or other business entities
which are not related corporations, and the remaining sixty percent (60%) of the
Premises is in the possession of Tenant or a related corporation, or (B) Tenant
gives notice (the "Expansion Election Notice") to Landlord within thirty (30)
days (with respect to which Expansion Election Notice time is expressly of the
essence) after Landlord has sent to Tenant a notice (the "Landlord Expansion
Space Availability Notice") setting forth the date prior to the stated
expiration date of the existing lease of such Expansion Space on which Landlord
reasonably expects the tenant of the Expansion Space identified in such notice
to tender possession of such Expansion Space vacant of such tenant, all
subtenants and occupants and free of the personal property of and all claims by
such tenant with respect to such Expansion Space that was identified in such
notice (such possession being hereinafter called "Vacant Possession"), (C) if a
Landlord Expansion Space Availability

                                      -45-
<PAGE>   47

Notice is sent after the earliest date on which a First Renewal Term Election
Notice may be sent by Tenant, Tenant has theretofore exercised its Extension
Option pursuant to a First Renewal Term Election Notice (or a Conditional First
Renewal Term Election Notice with respect to which the Renewal Condition was
withdrawn or deemed withdrawn) in accordance with Article 43 (EXTENSION OPTION)
and (D) Tenant complies with the conditions set forth below, Tenant shall have
the option (the "Limited Expansion Option") to lease all of the entire eighth
(8th), ninth (9th), tenth (10th), eleventh (11th), twelfth (12th), fourteenth
(14th) floors [there being no thirteenth (13th) floor] (said six (6) floors
being collectively called the "S & A Expansion Space"), the twentieth (20th),
twenty-first (21st), twenty- second (22nd), twenty-third (23rd), twenty-fourth
(24th), twenty-fifth (25th), twenty-sixth (26th) floors and the portion of the
twenty-seventh (27th) floor which is not leased pursuant to this Agreement (said
seven and one half (7 1/2) floors being collectively called the "D & P Expansion
Space" and, together with the S & A Expansion Space, collectively the "Expansion
Space") which are set forth in the Landlord Expansion Space Availability Notice
for a term commencing on the date Vacant Possession of the Expansion Space set
forth in the Landlord Expansion Space Availability Notice is tendered to Tenant
and ending on the last day of

                                      -46-
<PAGE>   48

the Term of the Lease (the "Expansion Term"), upon the same terms and conditions
set forth in the Lease (unless changed or modified by this Agreement or other
mutual agreement). Landlord and Tenant each acknowledge that Landlord need not
give a Landlord Expansion Space Availability Notice after July 31, 2003, whether
or not Vacant Possession of any Expansion Space is thereafter obtained by
Landlord. The measurement of the rentable square feet of such Expansion Space
shall be calculated by Landlord on the same basis as the twenty-eighth (28th)
and twenty-ninth (29th) floors of the Premises. Subject to the provisions of
additional condition X of this Section 46.01, Vacant Possession of such
Expansion Space will be tendered to Tenant on the date, if at all, on which
Vacant Possession of such floors is obtained by Landlord, at the Fixed Rent and
Additional Rent provided below. Notwithstanding the foregoing, Tenant may not
exercise the Limited Expansion Option for any Expansion Space unless at the time
the Expansion Election Notice is sent and, to the extent set forth below on the
first day of the Expansion Term, all of the following additional conditions W,
X, Y and Z are met:

            W. The Expansion Election Notice must state that Tenant elects to
add to the Premises the following portions of the Expansion Space set forth in
the Landlord Expansion

                                      -47-
<PAGE>   49

Space Availability Notice: [Tenant to insert description which must meet the
requirements of condition x of this Section 46.01].

            X. The Expansion Space so elected pursuant to the Limited Expansion
Option and set forth in the Expansion Election Notice must (1) if the Landlord
Expansion Space Availability Notice includes Expansion Space consisting of less
than two (2) full floors be all of such space except that any space which is
less than a full floor need not be included in an Expansion Election Notice
unless it is contiguous either to other portions of the Premises or to other
Expansion Space previously or contemporaneously included in an Expansion
Election Notice and (2) if the Expansion Notice includes Expansion Space
consisting of two (2) full floors or more, must be a minimum of two (2) full
floors and, in order to assure that all elected Expansion Space is contiguous to
other portions of the Premises, all such Expansion Space set forth in any
Expansion Election Notice must be contiguous (a) to the then Premises or (b) to
Expansion Space previously or contemporaneously included in an Expansion
Election Notice before Expansion Space which does not met the criteria set forth
in clauses (2) (a) or (2) (b) may be elected pursuant to an Expansion Election
Notice (e.g., with respect to the D & P Expansion Space, an

                                      -48-
<PAGE>   50

Expansion Election Notice may not include floor 24 unless either floors 20, 21,
22 and 23, as a group, or floors 25, 26 and the balance of 27, as a group, have
been so elected and then are occupied by Tenant and with respect to the S & A
Expansion Space, an Expansion Election Notice may not include floor 11 unless
either floors 8, 9 and 10, as a group, or floors 12 and 14, as a group, have
also been elected and are then occupied by Tenant).

            Y. No Expansion Election Notice may be sent by Tenant under this
Article unless at the time of sending the Expansion Election Notice and on the
first day of the Expansion Term (1) the most recent audited financial statement
of Tenant and each of the FOCUS Reports filed with the SEC during the twelve
(12) months prior to such first day shows a net worth of not less than $185
million and a Net Capital of not less than $56 million and (2) the Expansion
Election Notice is accompanied by such financial statement and FOCUS Reports.

            Z. Tenant shall not be in default under any of the terms, covenants
and conditions of the Lease beyond any notice and grace period hereunder at the
time it sends any Expansion Election Notice.

                                      -49-

            Section 46.02. In the event that Tenant validly exercises a Limited
Expansion Option for any Expansion Space:

            The Fixed Rent per rentable square foot with respect to such
Expansion Space, payment of which shall commence on the first day of the
Expansion Term, shall be an amount equal to aggregate of (A) the Fixed Rent per
rentable square feet for the 28th and 29th floors and (B) the Additional Rent
for Tax Escalation under Article 6 (Tax Payments) and for Expense Escalation
under Article 7 (ESCALATION) per rentable square foot for the 28th and 29th
floors. With respect to such Expansion Space, the Base Tax under Article 6 (TAX
PAYMENTS) shall be the Real Estate Taxes for the Tax Year in which any portion
of the Expansion Term shall fall and the Expense Base under Article 7
(ESCALATION) shall be the calendar year of the earliest year of the Expansion
Term. The Tenants Share, as used in said Articles 6 (TAX PAYMENTS) and 7
(ESCALATION) shall be increased based upon the number of rentable square feet of
said Expansion Space. The Expansion Term shall commence on the date of the
tender to Tenant of Vacant Possession of the Expansion Space.

<PAGE>   52

            Section 46.03. In the event Tenant validly exercises any Limited
Expansion Option under this Article, the parties shall immediately be bound
thereby without the execution of an amendment to this Lease; however, at the
request of either party, the parties shall promptly execute and deliver a
written amendment to this Lease reflecting the addition of such Expansion Space
as part of the Premises for the Expansion Term, the increase of the Fixed Rent
and the increase of the Tenant's Share as provided above by reason of the
addition of such Expansion Space. Except for such changes, the provisions of
this Lease shall apply with respect to such Expansion Space and such Expansion
Space shall be and become part of the Premises. Tenant will accept possession of
such Expansion Space, and the facilities thereto and improvements therein in the
then "AS IS" condition on the date of delivery thereof to Tenant and, except as
hereinafter provided, Landlord shall not be required to perform any work or to
give Tenant any work allowance whatsoever with respect to any such Expansion
Space. Notwithstanding the foregoing, in the event Landlord fails or is unable
to tender Vacant Possession of all or any portion of such Expansion Space to
Tenant on the proposed delivery date thereof as a result of Force Majeure, the
performance by Landlord of Removal Work or the holding over of the prior tenant
or otherwise, Landlord shall not be

                                      -51-
<PAGE>   53

subject to any liability whatsoever for such failure or inability to tender
Vacant Possession during the continuation of the Force Majeure, holding over by
such prior tenant or performance of such Removal Work, but the Fixed Rent and
Additional Rent shall not commence with respect to such portion of such
Expansion Space until the date on which Vacant Possession thereof is actually
tendered to Tenant. Notwithstanding the foregoing, if Vacant Possession of any
Expansion Space is not tendered by Landlord within twelve (12) months following
the stated expiration date of the existing lease of such Expansion Space, Tenant
may, by notice given to Landlord after such twelve (12) month period has expired
but prior to the date Vacant Possession is tendered to Tenant, elect to cancel
its Expansion Election Notice but only with respect to such Expansion Space as
to which such Vacant Possession has not been tendered. For purposes of computing
the twelve (12) month period referred to above, the Removal Period shall not be
included in such computation. Nothing herein shall operate to extend the
Expiration Date for any of the Premises (including but not limited to such
Expansion Space) beyond the date otherwise fixed for the expiration of the Term
or of the Expansion Term, as applicable.

            Section 46.04. Time shall be expressly of the essence with respect
to all notices given by Tenant under this Article, and the time periods for the
giving of such notices shall not be extended for any reason whatsoever.

            Section 46.05. In the event Tenant shall fail to send to Landlord an
Expansion Election Notice in response to a Landlord Expansion Space Availability
Notice within the applicable time period as provided herein, Tenant shall be
conclusively deemed to have failed to have exercised its Limited Expansion
Option with respect to such Landlord Expansion Space Availability Notice, and
Tenant agrees that no action taken subsequently by Landlord or by Tenant shall
operate to revive any rights of Tenant under this Article with respect to the
Expansion Space set forth in such Landlord Expansion Space Availability Notice.

            Section 46.06. Nothing contained in this Agreement or the sending to
Tenant of any Landlord Expansion Space Availability Notice or the sending by
Tenant of an Expansion Election Notice in response to a Landlord Expansion Space
Availability Notice shall be construed (1) to grant any rights to Tenant with
respect to (a) any Expansion Space prior to such space being required to be
expressly included in any Landlord Expansion Space

                                      -53-

Availability Notice or (b) any S & A Expansion Space which is either (i) not set
forth in a Conditional First Renewal Term Election Notice or (ii) was set forth
in a Landlord Expansion Space Availability Notice but not included in a valid
Expansion Election Notice sent in response to thereto (the space described in
clause (b), hereinafter the "Excluded S & A Expansion Space"), Tenant expressly
acknowledging that Landlord is under no duty to cause Vacant Possession of all
or any D & P Expansion Space or all or any Excluded S & A Expansion Space to be
delivered to Landlord or to be required to or be able to be delivered to
Landlord and that Landlord may never be required to or be able to send a
Landlord Expansion Space Availability Notice with respect thereto, and that
Landlord may, if it so elects in its sole discretion, actively deal in any
manner with the tenant under the Debevoise & Plimpton Lease and with the tenant
under the Sidley & Austin Lease in such a manner as may prevent Vacant
Possession of any or all D & P Expansion Space and of all or any Excluded S & A
Expansion Space from ever being so delivered or from being required to or being
able to be so delivered to Landlord, (2) to prevent Landlord from negotiating
with the tenant of the D & P Expansion Space or of the Excluded S & A Expansion
Space or from entering into one or more leases of all or any D & P Expansion
Space or all or any Excluded S & A Expansion Space

                                      -54-
<PAGE>   56

or modifications of the Debevoise & Plimpton Lease or of the Sidley & Austin
Lease affecting all or any D & P Expansion Space or all or any Excluded S & A
Expansion Space, which lease(s) or modification(s) may contain modifications to
the rental or other provisions thereof or grant renewal or extension options in
favor of the tenant(s) thereunder the term of which may extend past the Term of
this Lease as it may be extended, (3) to obligate Landlord to (a) refuse its
consent to any proposed sublease or assignment by a tenant in possession of all
or any D & P Expansion Space, or all or any Excluded S & A Expansion Space, (b)
accept a surrender of any or all D & P Expansion Space or all or any Excluded S
& A Expansion Space or (c) agree with the tenant of the D & P Expansion Space or
of the Excluded S & A Expansion Space to cancel or modify the rights of such
tenant with respect to all or any D & P Expansion Space or all or any Excluded S
& A Expansion Space or (4) to obligate Landlord to evict any tenant of all or
any D & P Expansion Space or of all or any Excluded S & A Expansion Space which
is in default under its lease thereof, even if the effect of any such action or
inaction described in clauses (1) to (4) inclusive considered singly or
cumulatively, may be to preclude Vacant Possession of any D & P Expansion Space
or all or any Excluded S & A Expansion Space from ever being delivered or being
able to be delivered to Landlord or may

                                      -55-
<PAGE>   57

otherwise materially and adversely affect the possibility of tendering of Vacant
Possession of D & P Expansion Space or Excluded S & A Expansion Space to Tenant.
Notwithstanding the foregoing, Landlord shall not enter into any amendment or
modification of the Sidley & Austin Lease (other than with respect to the
Excluded S&A Expansion Space) which shall have any adverse effect on the
potential rights of Tenant to any S & A Expansion Space, although it may enter
into such an amendment or modification of the Debevoise & Plimpton Lease even
though such amendment or modification may have such an adverse effect with
respect to the D & P Expansion Space. Landlord shall include in any Landlord
Expansion Space Availability Notice all Expansion Space which (a) Landlord
reasonably believes the tenant thereof will deliver Vacant Possession on a date
certain prior to the stated expiration date of the term of the lease of such
Expansion Space and (b) has not been included in any prior Landlord Expansion
Space Availability Notice.

            Section 46.07. If an Expansion Election Notice has been validly sent
by Tenant with respect to at least two (2) full floors of S & A Expansion Space
and the Expansion Term with respect to such S & A Expansion Space has not
commenced and if, prior to June 1, 2001 Landlord sends Tenant a Landlord 28 and
29 Availability Notice, Landlord

                                      -56-
<PAGE>   58

shall, in such notice, designate two (2) floors of S & A Expansion Space which
Tenant may surrender, and Tenant may, in its First 28 and 29 Renewal Term
Election Notice elect to cancel its Expansion Election Notice with respect only
to the two (2) floors of S & A Expansion Space so designated by Landlord.

            Section 46.08. In addition to the limitation of liability set forth
in Section 46.03, Tenant expressly waives any right to rescind this Lease under
Section 223-a of the New York Real Property Law or under any present or future
statute of similar import then in force and further expressly waives the right
to recover any damages, direct or indirect, which may result from Landlord's
failure to deliver Vacant Possession of the Expansion Space on the commencement
date of the Expansion Term. Tenant agrees that the provisions of this Article
are intended to constitute "an express provision to the contrary" within the
meaning of said Section 223-a. Any such failure to so deliver Vacant Possession
shall not extend the expiration date of the Expansion Term. Notwithstanding the
foregoing provisions of this Section 46.08, in the event that the failure to
deliver Vacant Possession of any Expansion Space on the commencement date of the
First Renewal Term is not the result of Force Majeure, the holding over of the
prior tenant or the

                                      -57-

performance of Removal Work, Tenant may, not earlier than sixty (60) days after
the commencement date of the First Renewal Term, elect to cancel its Expansion
Election Notice but only with respect to such Expansion Space with respect to
which Vacant Possession was not so delivered; provided, however, such election
to cancel shall not be effective if prior thereto Landlord has tendered Vacant
Possession of such S & A Expansion Space. For purposes of computing the sixty
(60) day period referred to above, the Removal Period shall not be included in
such computation.

            12. Landlord represents, warrants and covenants that:

            A. (1) The Building Equipment which serves the Additional 27th Floor
Premises shall be in working order on the date Vacant Possession of the
Additional 27th Floor Premises shall be delivered to Tenant.

               (2) The Building Equipment which serves Expansion Space set forth
in (a) a valid Expansion Election Notice or (b) a Conditional First Renewal Term
Election Notice with respect to which a Renewal Termination Notice has validly
withdrawn the Renewal Condition, shall be in

                                      -58-
<PAGE>   60

working order on the date Vacant Possession of such Expansion Space is tendered
to Tenant.

            B. No asbestos was used in the construction of the Additional 27th
Floor Premises or any Expansion Space by Landlord. Landlord has no actual
knowledge (as distinguished from imputed or implied knowledge) that any
Hazardous Substance (as so designated on the date of execution of this
Agreement) was used in the construction of the Additional 27th Floor Premises or
any Expansion Space. In the event any Hazardous Substance (as so designated as
of the date of execution of this Agreement) or asbestos is found in the
Additional 27th Floor Premises or in any Expansion Space set forth in (a) a
valid Expansion Election Notice or (b) a Conditional First Renewal Term Election
Notice with respect to which a Renewal Termination Notice has validly withdrawn
the Renewal Condition, Landlord shall, at its sole cost and expense, elect
either to (1) remove such Hazardous Substance (as so designated as of the date
of execution of this Agreement) and asbestos that is found in the Additional
27th Floor Premises or in such Expansion Space (the "Removal Work") or (2)
reimburse Tenant for the reasonable cost incurred by Tenant solely to remove
such Hazardous Substance and asbestos that is so found. In the event that
Landlord makes the Removal Election (hereinafter

                                      -59-
<PAGE>   61

defined), Landlord shall, after obtaining Vacant Possession of such Additional
27th Floor Premises or such Expansion Space, as the case may be, commence the
Removal Work with reasonable promptness, given the nature of the Removal Work
and the necessity to observe all safety requirements, Legal Requirements and
Insurance Requirements in connection with the prosecution of such Removal Work,
and thereafter prosecute to completion such Removal Work with reasonable
diligence given the nature of the Removal Work and the need to comply with all
safety requirements, Legal Requirements and Insurance Requirements with respect
to such Removal Work. For purposes of this Agreement, (x) Removal Work shall
include investigating whether Hazardous Substance (as so designated) or asbestos
is present, obtaining all necessary permits and preparing to commence the
physical activities in connection therewith as well as obtaining all necessary
government approvals for the work to be performed and as performed and (y) the
period of time during which Landlord has commenced and prosecuted such Removal
Work in accordance with the foregoing standard is called the "Removal Period".
For purposes of this Agreement, the election under clause 1 of this subparagraph
B shall be called the "Removal Election" and the election under clause 2 under
this subparagraph B shall be called the "Reimbursement Election". Landlord may
make the Removal

                                      -60-
<PAGE>   62

Election or Reimbursement Election at any time within ninety (90) days after
Landlord has actual (as distinguished from imputed or implied) knowledge of the
presence of Hazardous Substance (as so designated) or asbestos in such Expansion
Space; provided, however, if Vacant Possession is tendered to Tenant prior to
Landlord's obtaining such actual knowledge, Landlord shall immediately notify
Tenant of the facts of which it has actual knowledge with respect to the
presence of such Hazardous Substance and be deemed to have made the
Reimbursement Election.

            13. Landlord shall dedicate at least one (1) but not more than two
(2) elevators for use solely by Tenant to service those portions of the Premises
designated by Tenant provided that (A) implementing such request does not
violate the provisions of the Debevoise & Plimpton Lease disclosed to Tenant in
connection with the negotiation of this paragraph 13 relating, among other
matters, to the right of the tenant under the Debevoise & Plimpton Lease to
require Landlord to dedicate up to three (3) elevators for the exclusive use of
said tenant, and (B) Tenant complies with each of the following terms and
conditions:

                  (i) Tenant retains, at its sole cost and expense, Schindler
Elevator Corp. to report in writing to

                                      -61-
<PAGE>   63

Landlord and Tenant that the dedication desired by the Tenant is feasible.
Tenant shall provide Landlord with a copy of said report promptly upon its
receipt;

                  (ii) All work to be performed in connection with said
dedication shall be performed by Schindler Elevator Corp. and all expenses
incurred with respect to such dedication, including without limitation the cost
of conversion, reprogramming and rewiring, shall be paid for by Tenant; and

                  (iii) All such work shall be performed prior to 7:00 AM and
after 10:00 PM and shall comply with all of Landlord's Rules and Regulations,
Landlord's customary practices, and all Legal Requirements and Insurance
Requirements. Tenant shall reimburse Landlord for any cost incurred by Landlord
in connection with the dedication of said elevator or elevators including,
without limitation, the cost of on-the-job services requested by Tenant or
required by Landlord's Rules and Regulations or Landlord's customary practices
including, but not limited to, removal of waste and debris, dumpster, protection
of work in progress and guard service. If Tenant requests Landlord provide
on-the-job services during overtime hours, on weekends or during holidays,
Landlord shall make reasonable

                                      -62-
<PAGE>   64

efforts to accommodate Tenant and Tenant shall reimburse Landlord for all such
overtime, weekend and holiday costs incurred.

In the event that Landlord determines, in its reasonable judgment, that by
reason of damage to other elevators, or by reason of other events causing
inoperability of other elevators, or during periods scheduled for maintenance of
other elevators, in order to maintain adequate elevator service within any
portion of the Building, revocation of such dedication is necessary, Landlord
may revoke such dedication for so long as necessary, provided, however, Landlord
shall, promptly after Landlord determines in its reasonable judgment that the
need for such revocation has ceased, reinstate such dedication. Landlord
covenants that during the Term it will (a) maintain in operation the six (6)
elevators now servicing the Premises and the D & P Expansion Space (provided
that the foregoing covenant shall not be claimed or deemed breached by lack of
service of any of such elevators due to normal wear and tear and breakdowns, or
the performing by Landlord of routine or unusual maintenance, renovation,
refurbishing or repair work with respect to all or any of such six (6)
elevators) and (b) notwithstanding any other provision of this Agreement, not
modify the provision of the Debevoise & Plimpton Lease

                                      -63-
<PAGE>   65

so disclosed to Tenant so as to either (i) require Landlord to dedicate more
than three (3) elevators for the exclusive use of said tenant or (ii) otherwise
limit the access of Tenant to any elevators other than the three (3) which may
be so dedicated.

            14. Tenant represents that in the negotiation of this Agreement it
dealt with no broker(s) other than The Peregrine White Company, Inc. (the
"Broker") and no other broker participated in bringing about this Agreement.
Tenant hereby indemnifies and agrees to defend and hold Landlord harmless
against any claim or liability arising out of any inaccuracy or alleged
inaccuracy of the above representation. The parties hereto acknowledge that the
Broker will be paid a commission in accordance with a separate agreement between
Landlord and Broker. Landlord represents that to the best of Landlord's
knowledge, it has not dealt with any broker other than the Broker in connection
with this Agreement.

            15. Except as modified by this Agreement, the Lease shall remain in
full force and effect in accordance with its terms and (except for the
representations set forth therein) is hereby ratified and confirmed.

benefit of the parties hereto and their respective successors and permitted
assigns.
