                          SECOND AMENDMENT TO SUBLEASE

      This Second Amendment to Sublease (this "Amendment") dated as of the 7th
day of November 2002 by and between CHARLES SCHWAB & CO., INC. ("Sublandlord"),
having an office at 101 Montgomery Street, San Francisco, California 94104, and
INSTINET GROUP INCORPORATED ("Subtenant"), having an office at 3 Times Square,
New York, New York 10036.

                              W I T N E S S E T H:

      WHEREAS, Sublandlord, as sublandlord, and Subtenant, as subtenant, are
parties to that certain Sublease (the "Sublease"), dated as of December 18, 2001
and amended May __, 2002, for a portion of the Ground Floor Space, a portion of
the Mezzanine Space and the entire rentable space on floors 9, 10, 11 and 15
(being the 14th level without regard to the Mezzanine Space, there being no 13th
floor designated in the Building) in the building known as Plaza X, Harborside,
Jersey City, New Jersey (the "Building"); and

      WHEREAS, Subtenant desires to increase its authorized condenser water
allocation for supplemental cooling under the Sublease from 302 GPM as currently
provided in the Sublease (the "Existing Authorized Allocation") to 1017 GPM,
which is Subtenant's currently designed connected cooling load for such
purposes;

      WHEREAS, at Subtenant's request Sublandlord has (a) executed and delivered
to Overlandlord a change order to the Building Design Criteria ("Overlandlord
Change Order"), attached hereto as Exhibit A, with an estimated order of
magnitude cost acceptable to Sublandlord and Subtenant, as set forth in the
Overlandlord Change Order, for the design, purchase and construction by
Overlandlord of a fourth cooling tower and associated plate-and-frame heat
exchanger, pumps, power and controls and connection to the building cooling
system and the building management system, as shown in HLW-JBB specifications
dated September 25, 2002 (Additional Cooling Tower Cell), of a capacity to
supply additional condenser water, for the Building's condenser water system
(the "4th Tower"), and (b) entered into together with Subtenant a letter
agreement sent to Overlandlord dated September 20, 2002 (the "Overlandlord Tower
Letter"), providing for the construction of the 4th Tower to meet Subtenant's
condenser water requirements for supplemental cooling.

      WHEREAS, Subtenant wishes Sublandlord to execute and return to
Overlandlord the Overlandlord Change Order whereby Sublandlord becomes obligated
to Overlandlord for the cost of construction of the 4th Tower, but Sublandlord
is unwilling to do so unless and until Sublandlord and Subtenant enter into this
Amendment.

      NOW, THEREFORE, in consideration of the foregoing and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, Sublandlord and Subtenant hereby agree as follows:

A. All capitalized terms used herein without definition and defined in the
Sublease are used herein with the meaning assigned to such terms in the
Sublease.


<PAGE>
B. Sublandlord shall execute and return to Overlandlord the Overlandlord Change
Order.

C. Upon execution and return to Overlandlord of the Overlandlord Change Order
and upon completion of the design of the 4th Tower, Sublandlord will request
competitive bids through the Overlandlord for the 4th Tower in accordance with
the Overlandlord Change Order. Sublandlord will approve or reject, in its sole
discretion, the design of the 4th Tower in accordance with the Overlandlord
Change Order and the Overlease. Pursuant to the process in the Overlandlord
Change Order, Overlandlord shall have the sole right to establish the final
construction cost and Sublandlord and Subtenant shall have the right to confirm
that the process for establishing the final cost was correctly followed. If
requested by Sublandlord, Subtenant will confirm to Overlandlord in writing
Subtenant's approval of such design and finalized construction cost,
notwithstanding anything to the contrary contained in the Overlandlord Change
Order.

D. Subtenant agrees that the cost of construction of the 4th Tower, estimated by
Overlandlord in the Overlandlord Change Order to be $1,500,000.00, and as such
estimate shall be finalized by Overlandlord and Sublandlord, together with any
other costs associated therewith or with the amendment of the Overlease and
Sublease contemplated hereby including but not limited to the purchase,
installation and connection of the 4th Tower to the building cooling system and
the building management system, shall be paid by Subtenant by the immediate
reduction in the Sublease Allowance of $1,500,000.00 plus further reductions
therein in the event such costs exceed such initial reduction; provided,
however, in the event that (a) when such excess costs are billed to Subtenant
either the amount remaining of the Sublease Allowance, net of retainage, is less
than the amount of such excess costs, or Subtenant is in default under the
Sublease beyond any applicable notice and/or cure period under the Sublease, at
the election of the Sublandlord in writing, the excess costs shall be paid by
Subtenant as Sublease Additional Charges rather than by reduction of the
Sublease Allowance or (b) if such costs are less than the initial $1,500,000.00
(plus other associated costs) reduction described above, the excess of the
initial $1,500,000.00 (plus other associated costs) reduction over the actual
costs shall be credited to the Sublease Allowance or (c) if Sublandlord elects
in writing then some or all soft costs, including, but not limited to, legal
fees, engineering fees, consultants fees and Overlandlord fees, shall be paid by
Subtenant as Sublease Additional Charges rather than by reduction of the
Sublease Allowance. Such Sublease Additional Charges shall be paid within
fifteen (15) days after billing therefor by Sublandlord together with any
back-up information which Overlandlord has furnished to Sublandlord

E. Subtenant at Subtenant's sole cost will install "Piping Taps" on each floor
of the Subleased Premises with "Flow Meters" and "Temperature Sensors" in order
for Subtenant to temporarily obtain up to 715 GPM additional condenser water
allocation for supplemental cooling from the existing base building supply of
condenser water, as provided in the next paragraph. The design and installation
of the Piping Taps with Flow Meters and Temperature Sensors shall be subject to
the provisions of the Sublease and the Overlease (including, without limitation,
the delivery of plans and specifications to Overlandlord and Sublandlord for
their approval), and shall be at Subtenant's sole cost and expense.

F. Upon execution and return to Overlandlord of the Overlandlord Change Order
and until the date when the 4th Tower is operational, should Subtenant require
condenser water for itself in addition to the Existing Authorized Allocation,
upon request to Sublandlord by Subtenant,


                                       2
<PAGE>
Sublandlord in its sole and absolute discretion may furnish to Subtenant, as a
service provided by Overlandlord, condenser water for supplemental cooling up to
the amount of 715 GPM in addition to the Existing Authorized Allocation.
Pursuant to the Overlandlord Change Order Subtenant understands that
Overlandlord requires a fixed charge to be paid in order to make available to
Sublandlord supplemental condenser water in addition to Sublandlord's original
1,122 GPM allocation, and Subtenant agrees that it will pay such charge to
Sublandlord, regardless of usage of supplemental condenser water by Subtenant,
as Sublease Additional Charges, on the first day of each month in accordance
with such provisions of the Overlandlord Change Order. If the Subtenant is
receiving additional condenser water for supplemental cooling at any time prior
to completion of the 4th Tower, notwithstanding anything to the contrary above,
Sublandlord shall also have the right in its sole discretion to require
Subtenant to take whatever actions may be necessary to reduce Subtenant's
allocation of condenser water for supplemental cooling to 302 GPM (being its
Existing Authorized Allocation). If the Sublandlord so elects not to furnish
additional condenser water for supplemental cooling or to require Subtenant to
reduce its allocation of condenser water for supplemental cooling, then upon ten
(10) days' written notice from Sublandlord, Subtenant shall immediately take
whatever actions may be necessary to limit Subtenant's allocation of condenser
water for supplemental cooling to 302 GPM (being its Existing Authorized
Allocation) (or in the event of Subtenant's failure to do so, upon five (5)
days' notice from Sublandlord, then Sublandlord may do so) and Subtenant shall
no longer have any right to utilize such temporary additional condenser water
for supplemental cooling. Subtenant hereby releases and discharges Sublandlord
from all claims, liabilities and damages incurred by Subtenant by reason of or
in connection with any of the matters referred to in the previous sentence.

G. Upon the 4th Tower becoming operational, as confirmed by Sublandlord's
engineering consultant, Subtenant's Existing Authorized Allocation will be
increased from 302 GPM (being the Existing Authorized Allocation) by 715 GPM or
35% of the final total balanced flow rate of the 4th Tower, whichever is less,
so as to total a maximum of 1017 GPM; thereupon Subtenant shall have no further
right (if any) to use temporary additional condenser water pursuant to paragraph
F hereof. Subtenant's allocated share of the GPM of condenser water for
supplemental cooling as so increased may be utilized only by Subtenant or any
permitted assignee of the Sublease or subtenant of the Subleased Premises in
accordance with the Sublease.

H. The provisions of the Sublease relating to services to be provided by
Overlandlord, including, without limitation, Sections 2.5(a), (d) and (e) of the
Sublease shall apply to such temporary additional utilization of condenser water
for supplemental cooling as provided in paragraph F of this Amendment and
permanent increase in Subtenant's allocation of condenser water for supplemental
cooling upon the 4th Tower becoming operational as provided in paragraph G of
this Amendment. Sublandlord does not make, nor shall it impliedly make, any
representations concerning the adequacy of the condenser water for Subtenant's
requirements (including amount, flow and temperature).

I. Upon the 4th Tower becoming operational, as confirmed by Sublandlord's
engineering consultant, Sublandlord, its successors and assigns and other
subtenants, as designated by Sublandlord, will be entitled to use, reserve and
transfer for its or their use, the remainder of the condenser water for
supplemental cooling added by the 4th Tower not hereby allocated to Subtenant;
provided, however, in the event Sublandlord or such designee actually uses such


                                       3
<PAGE>
remainder of condenser water added by the 4th Tower (over and above the
condenser water allocation for supplemental cooling stipulated in the Overlease
prior to the construction of the 4th Tower) (the "Remaining 4th Tower
Allocation"), Sublandlord shall make (or cause a successor, assignee or other
subtenant to make) a cash payment to Subtenant in the amount of a percentage of
the hard costs of design, purchase and construction of the 4th Tower actually
charged to Subtenant hereunder equal to the percentage of the final total
balanced flow rate of the 4th Tower intended to be so utilized. If not
prohibited by the Overlease, Sublandlord agrees to exercise its right to obtain
the Remaining 4th Tower Allocation from Subtenant before obtaining condenser
water for supplemental cooling from Overlandlord over and above the condenser
water allocation for supplemental cooling stipulated in the Overlease prior to
the construction of the 4th Tower. The proviso in the first sentence and the
entire second sentence of this paragraph I will be of no force and effect after
the expiration or earlier termination of the term of the Sublease.

J. Subtenant will reimburse and indemnify Sublandlord for all other costs and
liabilities associated with the need to address Subtenant's excess connected
cooling loads, the construction, operation, maintenance, repair and upgrading of
the 4th Tower, the amendment of the Overlease and Sublease, including but not
limited to: legal fees, permit fees, engineering fees, fees from Overlandlord or
its consultants, payment to Overlandlord for additional cooling to be available
or the reservation thereof, reimbursement to Overlandlord and/or Sublandlord of
tenant costs for interrupted tenant operations evolving from shutdowns required
to the base building or tenant systems for the installation of the 4th Tower,
any liability of Sublandlord to any of its other subtenants by reason of the
performance by the Overlandlord of the Overlandlord Change Order, and any
reasonable costs charged by Overlandlord or others associated with the usage or
provision of cooling in excess of the Existing Authorized Allocation, such
amounts to be paid by Subtenant as Sublease Additional Charges within fifteen
(15) days after billing therefor by Sublandlord.

K. Sublandlord and Subtenant agree that it is their mutual intention that
Sublandlord shall not actually profit and shall not suffer actual financial loss
by reason of this Amendment and the acts and transactions contemplated thereby
and that Sublandlord will not realize a "profit" payable to Overlandlord
pursuant to Section 8.07 of the Overlease. In the event that Overlandlord
determines that Sublandlord will realize such a "profit" payable to Overlandlord
pursuant to Section 8.07, then, at Sublandlord's option, Sublandlord and
Subtenant will use commercially reasonable efforts to attempt to amend this
Amendment so as to eliminate any such "profit" payable to Overlandlord pursuant
to Section 8.07, without Sublandlord suffering any actual financial loss, and
without Subtenant suffering any actual additional financial loss by reason of
such amendment hereof, provided that each party shall pay its own counsel fees
and expenses in connection with such amendment hereof.

L. This Amendment may not be changed orally, but only by an agreement in writing
signed by the party against whom enforcement of any waiver, change, modification
or discharge is sought.

M. This Amendment constitutes the entire agreement between the parties and all
representations and understandings have been merged herein. In the event of any
inconsistency between this Amendment and the Overlandlord Change Order as to the
rights and obligations as between Subtenant and Sublandlord, the provisions of
this Amendment shall govern as between

                                       4
<PAGE>
Subtenant and Sublandlord. The Overlandlord Tower Letter is superceded by this
Amendment and shall be of no further force or effect.

N. Except as otherwise expressly set forth herein, the Sublease is in full force
and effect and is hereby ratified and confirmed and the terms, covenants,
conditions and agreements therein contained remain in full force and effect.

O. This Amendment is, at the option of Sublandlord, subject to and conditioned
upon a more formal consent thereto by Overlandlord in form and substance
satisfactory to Sublandlord, provided however, Subtenant shall be obligated
under paragraphs D and J hereof even in the event this Amendment is not
consented to by Overlandlord and/or as a result thereof this Amendment does not
become effective.

P. Subtenant and Sublandlord each represents that no broker brought about this
transaction and each agrees to indemnify and hold the other harmless from any
and all claims of any other broker with which such indemnifying party has dealt
arising out or in connection with negotiations of, or entering into of, this
Amendment.

Q. This Amendment may be executed in multiple counterparts, all of which taken
together shall constitute the same instrument.
