                            MUTUAL SERVICES AGREEMENT

                  MUTUAL SERVICES AGREEMENT (this "Agreement"), dated December
18, 2001, by and between INSTINET GROUP INCORPORATED, a Delaware corporation
(the "Seller"), and REUTERS AMERICA INC., a Delaware corporation (the
"Purchaser," and each of the Seller and the Purchaser, a "Party").

                  WHEREAS, the Purchaser and the Seller have entered into an
Asset Purchase Agreement (the "Asset Purchase Agreement"), dated December 18,
2001, pursuant to which the Seller agreed to sell the assets, rights, claims and
contracts used by the Seller exclusively in the business of development, sales,
marketing, support and distribution of the U.S. equity market research/real-time
financial market data platform currently marketed by the Seller as the "Research
and Analytics" ("R&A") product (the "Business"), and the Purchaser agreed to
assume certain liabilities and obligations of the Business; and

                  WHEREAS, the Seller desires that the Purchaser provide to the
Seller's customers certain services (as described herein) in support of the
Seller's services to such customers, and the Purchaser desires that the Seller
provide to the Purchaser certain services (as described herein) related to the
conduct of the Business.

                  NOW, THEREFORE, in consideration of the mutual promises
hereinafter set forth and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the Parties hereby agree as
follows:

                  1. Provision of Customer Support Services. The Purchaser shall
make available or cause to be made available to the customers of the Seller set
forth on Schedule A hereto (the "Protected Customers"), in support of the
Seller's services to the Protected Customers, the services and products of the
Business that are specified on Schedule A hereto (the "Customer Support
Services") for the period commencing on the date hereof and ending on the
eighteen month anniversary of the Closing Date (the "Transition Period"), on the
terms and conditions and with the functionality as specified on Schedule A
hereto. The Seller agrees that it will retain liability, pursuant to the Asset
Purchase Agreement, for any claim relating to or arising from the handling of a
customer order, including order entry, order routing and order execution.

                  2. Provision of Support and Transition Services. (a) The
Seller shall make available or cause to be made available to the Purchaser the
services that are specified on Schedule B hereto (the "Support Services"), for
the periods following the date hereof specified on Schedule B hereto (each such
period being a "Support Term"), unless sooner terminated in accordance with
Section 6 hereof. The Parties agree that the Support Services are intended to be
transitional only, and the Purchaser agrees to use its reasonable efforts to end
its need to use such Support Services as promptly as practicable, and in any
event not later than the end of the relevant Support Term. The Seller agrees to
cooperate with the Purchaser to facilitate the smooth transition of
responsibility for such Support Services from the Seller to the Purchaser or any
third party designated by the Purchaser.
<PAGE>
                  (b) The Seller agrees to cooperate with the Purchaser during
the Transition Period to make available customer lists, customer specifications
and other data in the Seller's possession to the extent related to the Business
and to make available from time to time during normal business hours employees
of the Seller, including, if requested, executive employees, to discuss the
Business, answer technical questions and assist in transition planning. During
the Transition Period as the Purchaser may reasonably request, the Seller agrees
to cooperate with, and provide reasonable assistance to, the Purchaser's sales
force to facilitate a smooth transition of account coverage and account
management of the customer accounts of the Business, and will provide reasonable
assistance to the Purchaser in training its sales force with respect to the
features and functionality of the R&A product.

                  3. Additional Services. If, following the execution of this
Agreement, the Parties determine that certain services were inadvertently
omitted from Schedule B hereto, then the Parties shall negotiate in good faith
to agree to the terms and conditions upon which such services would be added to
this Agreement, it being agreed that the charges for such services should be
determined on a basis consistent with the terms of this Agreement.

                  4. Compensation. (a) The fees (the "Customer Support Fees")
payable by the Seller to the Purchaser for the provision of the Customer Support
Services for the duration of the relevant Customer Term shall be the relevant
cost set forth on Schedule A, plus applicable statutory sales or value-added
taxes, as determined by the Purchaser.

                  (b) (i) In addition, the Seller shall pay to the Purchaser
certain non-recurring fixed costs incurred by the Purchaser in connection with
providing Customer Support Services (the "Non-Recurring Fixed Costs"); provided
that the aggregate of such costs shall not exceed $1,241,629. At the end of the
Transition Period, the Seller shall pay to the Purchaser an amount equal to
$1,241,629 less any amounts previously paid to the Purchaser pursuant to the
first sentence of this Section 4(b), regardless of whether relevant invoices
have been provided pursuant to Section 5.

                           (ii) The Parties agree that the costs of migrating
                  customers of the Business to the Improved BridgeStation
                  Terminal (as defined in Section 14(e)) shall be discussed and
                  incorporated into the broader discussions regarding the
                  process and scheduling of the RXN migration.

                  (c) The support fees (the "Support Fees") payable by the
Purchaser to the Seller from provision of the Support Services for the duration
of the relevant Support Term shall be the relevant cost set forth on Schedule B,
plus applicable statutory sales or value-added taxes, if any.

                  (d) The Purchaser shall be responsible for all costs, expenses
and charges incurred by the Seller under the lease agreement between the Seller
and BC Development Company dated November 1, 1992, as amended, related to the
software development center (the "Kansas Development Center") located at 11900
College Boulevard, Overland Park, Kansas, for the period commencing on the
Effective Date and ending on the date such lease is terminated in accordance
with its terms. The Purchaser shall reimburse the Seller in cash for these
costs, expenses and charges at the Closing for the period from the Effective
Date until the Closing and


                                       2
<PAGE>
for the periods from the Closing Date until the end of the lease term, at the
end of each fiscal quarter commencing at the end of the first fiscal quarter of
2002; provided that the Purchaser shall be entitled to offset any charges
related to the use by the Seller of space at the Kansas Development Center
calculated pursuant to Schedule B hereof.

                  (e) The Purchaser and the Seller agree to treat for U.S.
federal, state and local income tax purposes, all payments made pursuant to this
Agreement as payments for the provision of services.

                  5. Terms of Payment. (a) Except as otherwise expressly
provided herein, (i) the Seller shall invoice the Purchaser quarterly in arrears
for the Support Services provided by the Seller under this Agreement and (ii)
the Purchaser shall invoice the Seller quarterly in arrears for the Customer
Support Services provided by the Purchaser under this Agreement and for amounts
payable by the Seller pursuant to Section 4(b)(i) hereof.

                  (b) The Customer Support Fees shall be treated as Credit-Based
Payments pursuant to Sections 1.5 and 1.6 of the Asset Purchase Agreement and
shall be entered on the Quarterly Ledger Balance Statements, and paid, in
accordance with Sections 1.5(d) and (e) of the Asset Purchase Agreement. The
Support Fees, the fees related to the Kansas Development Center, amounts payable
by the Purchaser pursuant to Section 4(d), the amounts paid by the Seller to the
Purchaser pursuant to Section 4(b)(i) hereof and any sales taxes payable
hereunder shall be treated as Cash Payments pursuant to Section 1.5 of the Asset
Purchase Agreement.

                  6. Duration. Notwithstanding anything to the contrary herein,
the Seller shall not be required to provide or cause to be provided any Support
Service hereunder after the date which is 18 months following the date hereof
(except to the extent that a shorter maximum duration of a Support Service is
otherwise set forth in Schedule B hereto). Except as otherwise provided in
Schedule B hereto, the Purchaser may terminate at any time during the relevant
Support Term of any Support Service provided under this Agreement on a
service-by-service basis (and/or location-by-location basis where an individual
Support Service is provided to multiple locations) upon written notice to the
Seller identifying the particular Support Service (or location) to be so
terminated and the effective date of termination, which date shall not be less
than 30 Business Days after receipt of such notice by the Seller.

                  7. Performance of Services. Each Party shall perform the
Support Services or Customer Support Services, as applicable, with reasonable
skill and care and shall use at least that degree of skill and care that it
would exercise in similar circumstances in carrying out its own business. Each
Party shall take reasonably necessary measures to protect the other Party's data
that is processed by such Party from destruction, deletion or unauthorized
change; provided, however, that such Party shall be deemed to have satisfied
this obligation if the measures taken to protect the other Party's data are
equivalent to what it uses in carrying out its own business.

                  8. Indemnity. Each Party (the "Indemnifying Party") hereby
agrees to indemnify, hold harmless and defend the other Party and its affiliates
and their respective officers, directors, agents, employees, consultants,
shareholders, members, partners, agents and representatives and all successors
and assignors of the foregoing (the "Indemnified Parties") from and against all
Damages arising out of the other Party's performance or non-performance of


                                       3
<PAGE>
this Agreement, except to the extent occasioned by the Indemnified Party's
willful misconduct or gross negligence.

                  9. Method of Asserting Claims. All claims by any Indemnified
Party under Section 8 of this Agreement shall be asserted and resolved as
follows:

                  (a) In the event that (x) any claim, demand or Proceeding is
asserted or instituted by any Person other than the parties hereto which could
give rise to Damages for which an Indemnifying Party would be liable to an
Indemnified Party hereunder (such claim, demand or Proceeding, a "Third Party
Claim") or (y) any Indemnified Party hereunder shall have a claim to be
indemnified by any Indemnifying Party hereunder which does not involve a Third
Party Claim (such claim, a "Direct Claim"), the Indemnified Party shall as
promptly as possible send to the Indemnifying Party a written notice specifying
the nature of such claim or demand and the amount or estimated amount (which
estimate shall not be conclusive of the final amount of such claim and demand)
(a "Claim Notice"); provided, however, that any failure to give such notice will
not waive any rights of the Indemnified Party except to the extent that the
rights of the Indemnifying Party are actually prejudiced.

                  (b) In the event of a Third Party Claim, the Indemnifying
Party shall be entitled to participate therein and, if it so desires, to assume
the defense thereof with counsel reasonably satisfactory to the Indemnified
Party and, after notice from the Indemnifying Party to the Indemnified Party of
its election to assume the defense thereof, except as provided below, the
Indemnifying Party shall not be liable to such Indemnified Party under Section 8
of this Agreement for any fees of other counsel or any other expenses, in each
case subsequently incurred by such Indemnified Party in connection with the
defense thereof, other than reasonable costs of investigation. Notwithstanding
an Indemnifying Party's election to assume the defense of a claim, the
Indemnified Party shall have the right to employ separate counsel and to
participate in the defense of such claim, and the Indemnifying Party shall bear
the reasonable fees, costs and expenses of such separate counsel if: (i) the use
of counsel chosen by the Indemnifying Party to represent the Indemnified Party
would present such counsel with a conflict of interest, (ii) the actual or
potential defendants in, or targets of, any such claim include both the
Indemnifying Party and the Indemnified Party, and the Indemnified Party shall
have reasonably concluded that there may be legal defenses available to it which
are different from or additional to those available to the Indemnifying Party
(in which case the Indemnifying Party shall not have the right to assume the
defense of such claim on the Indemnified Party's behalf), (iii) the Indemnifying
Party shall not have employed counsel reasonably satisfactory to the Indemnified
Party to represent the Indemnified Party within a reasonable time after notice
of the institution of such claim, or (iv) the Indemnifying Party shall have
authorized the Indemnified Party to employ separate counsel at the Indemnifying
Party's expense. If an Indemnifying Party assumes the defense of a claim, no
compromise or settlement thereof may be effected by the Indemnifying Party
without the Indemnified Party's prior written consent unless (a) there is no
finding or admission of any violation of law and no effect on any other claims
that may be made against the Indemnified Party and (b) the sole relief provided
is monetary damages that are to be paid in full by the Indemnifying Party.

                                       4
<PAGE>
                  (c) In the event of a Direct Claim, unless the Indemnifying
Party notifies the Indemnified Party within 90 days of receipt for a Claim
Notice that it disputes such claim, the amount of such claim shall be
conclusively deemed a liability of the Indemnifying Party hereunder and shall be
paid to the Indemnified Party immediately.

                  (d) From and after the delivery of a Claim Notice hereunder,
at the reasonable request of the Indemnifying Party, the Indemnified Party shall
grant the Indemnifying Party and its representatives all reasonable access to
the books, records and properties of the Indemnified Party to the extent
reasonably related to the matters to which the Claim Notice relates. The
Indemnifying Party will not, and shall require that its representatives do not,
use (except in connection with such Claim Notice) or disclose to any third
Person other than the Indemnifying Party's representatives (except as may be
required by applicable Laws) any information obtained pursuant to this paragraph
which is designated as confidential by the Indemnified Party. All such access
shall be granted during normal business hours, shall be subject to the normal
safety regulations of the Indemnified Party, and shall be granted under
conditions which will not interfere with the business and operations of the
Indemnified Party.

                  (e) Any and all disputes arising out of any claim to
indemnification pursuant to paragraph 8 of this Agreement shall be resolved in
accordance with the provisions of Sections 16 and 17 of this Agreement.

                  (f) In the event that an Indemnified Party has a right against
a third party with respect to any Damages paid to such Indemnified Party by an
Indemnifying Party, then such Indemnifying Party shall, to the extent of such
payment, be subrogated to such rights of such Indemnified Party.

                  10. Limitation of Liability. No Party shall be liable to the
other Party or any third party for any special, punitive, consequential or
exemplary damages (including lost or anticipated revenues or profits relating to
the same) arising from any claim relating to this Agreement or any of the
Customer Support Services or Support Services provided hereunder, whether such
claim is based on warranty, contract, tort (including negligence or strict
liability) or otherwise, even if an authorized representative of such Party is
advised of the possibility of likelihood of the same. However, any indemnity
related to a Third Party Claim shall include any such consequential, special,
punitive or exemplary damages recovered by any third party pursuant to such
claim. In addition, such Party shall not be liable to the other Party or any
third party for direct or incidental damages arising from any claim relating to
this Agreement or any of the Customer Services or Support Services provided
hereunder or required to be provided hereunder to the extent that such direct or
incidental damages are caused by the negligence or willful misconduct of such
other Party.

                  11. Specified Review Meetings. In addition to any other review
meeting that may be deemed appropriate by the Parties, the Parties shall agree
to hold and attend the review meetings detailed below (the "Review Meetings")
(it being understood that no performance obligations shall arise out of any such
meetings unless explicitly agreed to by the Parties in writing):

                                       5
<PAGE>
                  (a) Monthly performance review: such a review shall consider,
without limitation, integration planning, client conversions, customer support,
service levels, operational changes and orders;

                  (b) Monthly change review: such a review to consider potential
modifications or changes to the Customer Support Services or the introduction of
new services by the Purchaser and the potential impact of such changes on the
Protected Customers;

                  (c) Quarterly review: Such a review shall consider, without
limitation, technical/operational integration progress, sales
issues/implications, client acceptance, product
integration/enhancements/schedules/roll-out plans;

                  (d) Price reviews: such reviews to take place at either
Party's request or in connection with the extension of any Support Term.

The Purchaser and the Seller each agree to designate persons to constitute a
working group for the purposes of attending, and participating in, the Review
Meetings.

                  12. Duty to Inform. On a quarterly basis at the monthly change
review meetings, the Purchaser shall notify the Seller of any developments and
proposed developments to the R&A product and shall provide pre-rollout product
testing upon the Seller's reasonable request. The Purchaser shall give the
Seller reasonable prior written notice of all modifications, improvements,
alterations or other changes to the R&A product which are reasonably likely to
materially impact the Seller or any of the Customer Support Services provided to
a Protected Customer and shall give the Seller at least 60 days' notice of the
termination of the R&A product.

                  13. Duty to Respond. The Purchaser agrees to (i) receive,
review and consider in good faith all input received from the Seller regarding
the subject matter of the Review Meetings that is communicated through members
of the working group designated by the Parties and (ii) respond in writing
within 30 days of receiving a written request for a response regarding any item
of input received with respect to the Purchaser's proposed course of action
after consideration of such item (it being understood that the course of action
with respect to such item remains within the Purchaser's sole discretion). If
the Seller is not reasonably satisfied with the Purchaser's written response to
such item, the Seller may then escalate such item to more senior officials
within the Seller's and the Purchaser's organization and the Purchaser and the
Seller shall make such senior officials reasonably available for the purpose of
resolving such escalated matters (it being understood that the ultimate course
of action with respect to such item remains within the Purchaser's sole
discretion).

                  14. Migration Payments. (a) The Purchaser will pay to the
Seller the following amounts based on the following conditions: (i) $225,000 if
the Completion Date is more than 30 days prior to the Target Completion Date;
(ii) $450,000 if the Completion Date is more than 60 days prior to the Target
Completion Date; (iii) $675,000 if the Completion Date is more than 90 days

Completion Date is more than 150 days prior to the Target Completion Date; or
(vi) $1,350,000 if the Completion


                                       6
<PAGE>
Date is more than 180 days prior to the Target Completion Date. The Parties
agree that such amounts shall not be cumulative. If 150 days after the
Completion Date there are contracts in place for fewer than 80% of the Instinet
R&A terminals deployed at customer sites at the Commencement Date (excluding
contracts for which notices of cancellation have been delivered) any amount
payable by the Purchaser in accordance with the immediately preceding sentence
shall be reduced to an amount equal to the product of (x) the amount otherwise
payable before reduction and (y) the number of terminals for which contracts are
in place (excluding contracts for which notices of cancellation have been
delivered) divided by the number of Instinet R&A terminals deployed at customer
sites at the Commencement Date.

                  (b) The Seller will pay to the Purchaser the following amounts
based on the following conditions: (i) $225,000 if the Completion Date does not
occur within 30 days after the Target Completion Date; (ii) $450,000 if the
Completion Date does not occur within 60 days after the Target Completion Date;
(iii) $675,000 if the Completion Date does not occur within 90 days after the
Target Completion Date; (iv) $900,000 if the Completion Date does not occur
within 120 days after the Target Completion Date; (v) $1,125,000 if the
Completion Date does not occur within 150 days after the Target Completion Date;
or (vi) $1,350,000 if the Completion Date does not occur within 180 days after
the Target Completion Date. The Parties agree that such amounts shall not be
cumulative.

                  (c) All payments pursuant to this paragraph shall be treated
as Cash Payments and shall be payable pursuant to Section 1.5 of the Asset
Purchase Agreement.

                  (d) Notwithstanding anything to the contrary herein, if the
Completion Date has not occurred by the twelve month anniversary of the Closing
Date, for every 30 day period following such twelve month anniversary of the
Closing, the maximum period for which the payments set forth in Section 14(a)
and 14(b) shall be due shall be reduced by thirty days and the maximum payments
which could be due to either the Purchaser or the Seller, as the case may be,
pursuant to Section 14(a) and 14(b) shall be reduced by $225,000. If the
Commencement Date occurs on a date that is later than the eighteen-month
anniversary of the Closing Date, no payments pursuant to Section 14 shall be due
to or from either Party and Sections 14(a) and (b) shall be of no further
effect.

                  (e) As used in this Section 13, (i) "Target Completion Date"
shall mean that date which is 9 months after the Commencement Date, (b)
"Commencement Date" shall mean that date on which the Purchaser certifies in
good faith to the Seller the completion of an R&A replacement product
incorporating no less than 75% of the Minimum Functionality, at which point the
resultant product will be referred to herein as the "Improved BridgeStation
Terminals" and (c) "Completion Date" shall mean that date on which (i) customers
of the Business shall have agreed in writing to migrate an aggregate of that
number of Instinet R&A terminals which equals 80% of the Instinet R&A terminals
deployed at customer sites at the Commencement Date to Improved BridgeStation
Terminals and shall not have given notice of cancellation of same and (ii) 100%
of the Protected Customers shall have agreed in writing to migrate all of their
Instinet R&A terminals to Improved BridgeStation Terminals or otherwise
cancelled their subscriptions to the Instinet R&A product. In completing the
Improved BridgeStation Terminals, the Purchaser shall take into account the
input of the Seller received by the Purchaser


                                       7
<PAGE>
during the Review Meetings and shall make commercially reasonable efforts to
incorporate the prioritization of the matters set forth on Annex A.

                  15. Inspection of Records. During the Transition Period, the
Seller shall upon reasonable notice from the Purchaser provide to the Purchaser
free and full access during normal business hours to the books and records of
the Seller related to the Seller's provision of services hereunder and the
Purchaser shall have the right to consult with such officers, employees and
other representatives of the Seller as may reasonably be required in order that
the Purchaser may have reasonable opportunity to make such inspections and
investigations as the Purchaser may reasonably desire to make in connection with
the charges imposed hereunder.

assigns. This Agreement shall not be assignable without the prior written
consent of the other Party; provided, however, that either Party may assign all
or a part of its rights under this Agreement to an affiliate; provided, further
that no such assignment shall relieve any Party of any of its obligations
hereunder.

                  19. Governing Law. This Agreement shall be governed by, and
construed in accordance with, the laws of the State of New York without
reference to the choice of law principles thereof.

                  20. Resolution of Disputes; Consent to Jurisdiction. (a) The
Purchaser and the Seller shall resolve any dispute which may arise out of or in
connection with this Agreement pursuant to Sections 1.6 and 9.8 of the Asset
Purchase Agreement, as applicable.

                  (b) The Parties agree that jurisdiction and venue in any
action brought by any Party pursuant to this Amendment shall properly lie and
shall be brought in any federal or state court located in the Borough of
Manhattan, City and State of New York. By execution and delivery of this
Agreement, each Party irrevocably submits to the jurisdiction of such courts for
itself and in respect of its property with respect to such action. The Parties
irrevocably agree that venue would be proper in such court, and hereby
irrevocably waive any objection that such court is an improper or inconvenient
forum for the resolution of such action.

                  21. Force Majeure. If by reason of labor disputes, strikes,
lockouts, riots, war, acts of terrorism, inability to obtain labor or materials,
earthquake, fire or other action of the elements, accidents, power blackouts,
governmental restrictions, appropriation or other cause beyond the reasonable
control of a Party hereto, either Party is unable to perform in whole or in part
its obligations as set forth in this Agreement, then such Party shall be
relieved of those


                                       9
<PAGE>
obligations to the extent it is so unable to perform and such inability to
perform shall not make such Party liable to the other Party. Neither Party shall
be liable for any loss, injury, delay or damages suffered or incurred by the
other Party due to the above causes.

                  22. Counterparts. This Agreement may be executed in one or
more counterparts, each of which shall be deemed an original, and all of which
shall constitute one and the same Agreement.

                  23. Confidentiality. Each of the Parties agrees to be bound by
the confidentiality provisions of Article V of the Intellectual Property
License, by and between the Purchaser and the Seller, dated as of December 18,
2001, with respect to any information disclosed by one Party to another Party
for the purpose of carrying out this Agreement or otherwise accessible to such
other Party during the performance hereunder, and the terms and conditions of
such Article V are incorporated by reference into this Agreement.

                  24. Independent Contractor; No Agency. Nothing contained in
this Agreement, as such, shall be construed as creating any agency, partnership,
or other form of joint enterprise between the Parties. The relationship between
the Parties shall at all times be that of independent contractors with respect
to the matters contemplated by this Agreement. Neither Party shall have
authority to contract for or bind the other Party in any manner whatsoever. This
Agreement confers no rights upon a Party except those expressly granted herein.

                  25. Waivers and Amendments. No modification of or amendment to
this Agreement shall be valid unless in a writing signed by the Parties
referring specifically to this Agreement and stating the Parties' intention to
modify or amend the same. Any waiver of any term or condition of this Agreement
must be in a writing signed by the Party sought to be charged with such waiver
referring specifically to the term or condition to be waived, and no such waiver
shall be deemed to constitute the waiver of any other breach of the same or of
any other term or condition of this Agreement.

Functionality Protection, Migration, Etc.

                  With respect to the installed terminals for the Protected
Customers listed on Attachment 1, the Purchaser shall, for a period of 18 months
following the Closing Date (as defined in the Asset Purchase Agreement) (a)
maintain the functionality to those desktops described on Attachment 2 (the
"Minimum Functionality") and (b) maintain a substantially similar level of
account management as has been historically provided by the Seller's sales and
account management personnel ((a) and (b) collectively, the "Customer Support
Services").

                  The Purchaser shall be free to migrate the Protected Customers
to other products offered by the Purchaser at any time during and after that 18
month period, provided that during such eighteen (18) month period the Minimum
Functionality is preserved in all material respects (it being understood that
Reuters' expectation is to enhance an existing BridgeStation product with these
functionalities and migrate clients to an Improved BridgeStation Terminal);
provided further that the Purchaser agrees during such 18 month period to effect
any migration first with customers of the R&A product who are not Protected
Customers before migrating Protected Customers unless a Protected Customer
requests migration.

Price Protection

                  The Seller shall pay quarterly to the Purchaser pursuant to
Section 1.5 of the Asset Purchase Agreement the amounts listed in the column
below entitled "December Monthly Trading Discount" for the 18 month period
commencing on the date hereof (such Trading Discount, the "Management Fees"),
plus applicable statutory sales or value-added taxes, as determined by the
Purchaser. The Trading Discount to the Purchaser shall be reduced proportionally
by any cancellations of the R&A product (and will be increased for any
additional terminals installed in accordance with the last paragraph of this
section).

                  The Purchaser shall not, during the Transition Period, raise
the list price described below for R&A products supplied as of the Effective
Date to the Protected Customers, except that the Purchaser shall be entitled to
charge in addition to such list prices (i) applicable taxes and exchange fees,
to the extent such taxes and exchange fees increase after the Closing Date and
(ii) communications expenses in excess of those currently charged to the
Purchaser pursuant to this Agreement; provided that the Purchaser may not raise
the charges for communications expenses unless the aggregate of such expenses
charged to the Purchaser by its telecommunications carrier in respect of the
Protected Customers exceeds 105% of the aggregate telecommunications expenses
charged to such Protected Customers. If the Purchaser increases the
telecommunications charges to any Protected Customer, (x) such charges will not
exceed the cost of such charges paid by the Purchaser to its telecommunications
carrier in respect of such Protected Customer and (y) the Purchaser shall modify
the charges to all of the Protected Customers such that each Protected Customer
is charged no more than the cost of the telecommunications charges paid by the
Purchaser to its telecommunications carrier with respect to such Protected
Customer. In addition, the Purchaser shall not charge any Protected Customer
(e.g., by "bundling" charges) for any communications expenses for which such
customer was not being charged as of the Effective Date. Before billing any
increased amounts to any customers,


                                      A-1
<PAGE>
the Purchaser shall notify the Seller no later than 45 Business Days prior to
the such billing and shall afford the Seller the opportunity to subsidize, in
whole or in part, such increased amounts.

                  In addition, the Purchaser shall, upon the request of the
Seller and during the Transition Period, install additional R&A terminals at the
request of Protected Customers at the expense of the Protected Customer and for
a price consistent with the pricing schedule attached hereto as Attachment 2 and
the agreements in the immediately preceding paragraph. The Purchaser shall give
the Seller the opportunity to subsidize, in whole or in part, such installation
charges and such list prices.

                  Protected Customers - The Protected Customers, the list price
and the management fee payable by the Seller with respect to each Protected
Customer is set forth on Attachment 3 to this Schedule A.

EXCEPT AS SPECIFICALLY STATED IN THE FOLLOWING TABLE, THE INITIAL TERM FOR ALL
SUPPORT SERVICES SHALL COMMENCE AS OF THE CLOSING DATE AND SHALL TERMINATE ON
EIGHTEEN-MONTH ANNIVERSARY OF THE CLOSING DATE.

                  The Seller shall provide the infrastructure products and
services listed on Attachment 1, including the client engineering, client
support and network and data center services listed thereon. The Purchaser shall
pay to the Seller for each quarter (or portion thereof) that services are used
an amount equal to the product of the total monthly allocations or costs set
forth in Attachment 2 times 3. At the end of each quarter the Parties shall
review the Purchaser's actual monthly utilization, based on the Seller's time
tracking system, and shall adjust the total monthly allocation amounts to take
into account any discrepancy between actual utilization for the last month of
such quarter and estimated utilization, such change to be effective for the
subsequent quarter.

                  With respect to each customer of the Business, the Purchaser
shall pay to the Seller for each quarter (or portion thereof) that such customer
subscribes to the R&A product an amount equal to the product of the total
monthly communications fees set forth opposite such customer's name on
Attachment 3 times 3. At the end of each quarter the Parties shall review the
Purchaser's actual monthly utilization, and shall adjust the monthly charges to
take into account any changes in the circuit allocations, such change to be
effective for the subsequent quarter.

                  With respect to each data center facility, the Purchaser shall
pay to the Seller for each quarter (or portion thereof) the data center facility
is utilized by the Purchaser an amount equal to the monthly allocation set forth
opposite such data center on Attachment 4 times 3. At the end of each quarter
the Parties shall review the Purchaser's actual monthly utilization, and shall
adjust the total monthly allocation amounts to take into account any changes in
data facility usage, such change to be effective for the subsequent quarter.

                  With respect to other services, the Purchaser shall pay to the
Seller for each quarter (or portion thereof) that such services are used an
amount equal to the fees set forth opposite such service on Attachment 5 times
3. At the end of each quarter the Parties shall review the Purchaser's actual
monthly utilization of such services, and shall adjust the total monthly charges
to take into account any changes in usage of the service, such change to be
effective for the subsequent quarter.

                  With respect to each of the Support Fees, if there has been a
material change in the Purchaser's usage of such service, which is reasonably
likely to continue into subsequent quarters, such material change shall be
factored in the total monthly allocation, cost or charges for the succeeding
fiscal quarter, such change to be effective for the subsequent quarter.
