Parent or any other Reuters Entity to: (i) permit or direct Reuters products or services to be softed through channels other than the Company or any Reuters Entity, so long as such actions do not violate Sellers exclusivity obligations set
forth in Section 5.10; (ii) invest in or own any debt securities or other debt obligations of any Person; (iii) invest in any Person which invests in, manages or operates a Competing Business, so long as the aggregate yearly revenue that such Person

their respective subsidiaries (collectively, the Unrestricted Companies), or (B) impose upon Parent or any other Reuters Entity any obligation with respect to the present or future activities of the Unrestricted Companies.

ReutersStations through any other Person during the Exclusivity Period so long as, at such time such additional softing is initiated or increased, such Exclusive Soft Dollar Customer is softing ReutersStations through the Company for at least its
Exclusive Soft Dollar Amount; provided, further, that in the event that Buyer or the Company does not pay any amount invoiced by Reuters America LLC or its Affiliates to the Company for ReutersStations on behalf of any Exclusive

37



---

Buyer or the Company, as applicable, does not pay such overdue amount within ten (10) days of receipt of written notice thereof from Reuters America LLC or
its Affiliates, the Exclusive Soft Dollar Amount of the applicable Exclusive Soft Dollar Customer shall be reduced by such overdue amount and Sellers exclusivity obligations pursuant to this Section 5.10 shall be correspondingly reduced by
such overdue amount with respect to such Exclusive Soft Dollar Customer until such time that Buyer or the Company, as applicable, pay such overdue amount.



5.11 Transfers of Sellers Assets. Parent and Seller hereby agree and covenant that, on and after the date hereof and until all of their
respective indemnification obligations under Articles IX and X have terminated, no sale, assignment or transfer of all or substantially all of Sellers assets to any Person (including Parent and any Affiliate of Parent) shall occur, pursuant to
a corporate reorganization or otherwise, unless an entity with a net asset value equivalent or higher to the net asset value of Seller as of the date of this Agreement unconditionally assumes or guarantees all of Sellers obligations under this
Agreement and the Related Agreements.

Providers. From and after the Closing and until December 31, 2005, Buyer shall not and shall cause each of its subsidiaries (including for the avoidance of doubt, the Company) not to, directly or indirectly, enter into any agreement,
understanding or arrangement, or solicit or offer to enter into any agreement, understanding or arrangement, with any of the Persons listed on Schedule 5.12 or any of their respective Affiliates (each a Third Party Data Provider)
pursuant to which customers of Buyer or any of its subsidiaries (including for the avoidance of doubt, the Company) would soft products and/or services of such Third Party Data Provider through Buyer or any of its subsidiaries (including for the
avoidance of doubt, the Company) on an exclusive basis; provided that, in the absence of any such agreement, understanding or arrangement between Buyer and its subsidiaries and such Third Party Data Provider, the voluntary decision by any client of
Buyer or the Company to soft 100% of the services provided by such Third Party Data Provider shall not be deemed to be a violation of this Section. Seller hereby acknowledges and agrees that, notwithstanding the indemnity provisions set forth in
Article IX and Article X, Sellers sole and exclusive remedy with respect to any breach by Buyer or any of its subsidiaries (including the Company) of the provisions of this Section 5.12 shall be limited only to the termination of Sellers

ARTICLE VIII



PERSONNEL,
EMPLOYMENT ARRANGEMENTS AND EMPLOYEE BENEFITS



8.1
In-Scope Employees. The current employees of the Company (the Company Employees) who, on the Closing Date, are actively employed by the Company or are



41



---

absent from active employment due to temporary illness, short-term disability or approved vacation or temporary leave of absence that is scheduled to last,
or has been approved for benefits by the applicable Parent benefit carrier to receive benefits for, six months or less are hereinafter referred to as the In-Scope Employees. Those Company Employees who are not In-Scope Employees
are hereinafter referred to as Excluded Employees.



Seller shall assume, satisfy and indemnify, or pay or reimburse, Buyer with respect to (i) any and all Liabilities related to the Excluded Employees and any and all Liabilities related to any employee who is no longer employed by the
Company as of the Closing Date and (ii) any and all Liabilities related to the In-Scope Employees, including, in all cases without limitation, Liabilities under the Seller Plans except to the extent such Liabilities (x) relate to In-Scope
Employees and (y) (A) are accrued as Liabilities on the Historical Financial Statements for the year ended December 31, 2004, (B) are incurred and relate to services rendered in the period from January 1, 2005 to the Closing to the extent such
Liabilities are incurred in the ordinary course of business consistent with past practice, (C) are incurred in and relate to services rendered in the period following the Closing, or (D) are expressly assumed by Buyer pursuant to this Article VIII.



8.2 Buyer Benefit Plans. Except as otherwise provided
by law or this Agreement, effective as of the Closing Date, the In-Scope Employees shall cease all active participation in and to accrue further benefits under the Seller Plans, and neither Buyer nor any of its Affiliates shall have any Liabilities
under the Seller Plans other than (x) as provided in this Agreement and (y) Liabilities with respect to In-Scope Employees under the Company Plans. Effective as of the Closing Date and through the first anniversary of the Closing Date, Buyer will
provide each In-Scope Employee with (i) a base salary or hourly wage rate, as applicable, that is at least equal to the base salary or hourly wage rate paid to such In-Scope Employee by the Company (or, where applicable, an Affiliate thereof)
immediately prior to the Closing, provided, however, that Buyer may, or may cause the Company to, reduce any such base salary or hourly wage rate to the extent consistent with reductions generally imposed on similarly situated
employees in Buyers institutional brokerage business; (ii) a job position that is a comparable or better position as such In-Scope Employee had immediately prior to the Closing and (iii) benefits under Buyer Plans (including, without
limitation, health benefits, severance policies, 401(k) plans and general employment policies and procedures, subject to the terms and conditions of such Buyer Plans as in effect from time to time) which are substantially comparable in the aggregate
to benefits under such Buyer Plans that are provided to similarly situated employees of the Buyer and its Subsidiaries; provided, however, that nothing in this Article VIII shall prevent the Buyer and its Subsidiaries from making any
change required by applicable Legal Requirements or from amending or terminating any such Buyer Plan in any respect or from terminating the employment of any In-Scope Employee following the Closing; and, provided further, that this
Article VIII shall not require any duplication of benefits.



8.3 Credit for Service. To the extent permitted under applicable law, Buyer shall (i) give each In-Scope Employee credit for all purposes, including without limitation eligibility, vesting, waiting period and benefit accrual
(excluding benefit accrual for purposes of a defined benefit pension plan) for all service with Seller, the Company and any of their respective Affiliates or predecessors under all Buyer Plans in which such employee participates; provided,
however, that with respect to any benefit plan that Buyer adopts following the Closing Date for the benefit of In-Scope Employees and other Buyer employees, for purposes of benefit accrual such service credit will be given to In-Scope
Employees to the extent past service is



42



---

credited under such plan to similarly situated Buyer employees; provided, further, that no such credit shall be provided in any circumstances
that would result in duplicative benefits; (ii) waive any pre-existing condition limitation under welfare benefit plans of Buyer or its Affiliates applicable to In-Scope Employees or their respective spouses or eligible dependents to the extent such
pre-existing condition limitation would have not applied to, or been satisfied with respect to, such individual under the corresponding Seller Plan; and (iii) recognize or cause to be recognized the dollar amount of all expenses incurred by In-Scope
Employees and their respective spouses or eligible dependents during the calendar year in which the Closing occurs for purposes of satisfying the deductible and co-payment or out-of-pocket limitations for such calendar year under the relevant
employee welfare benefit plans of Buyer or its Affiliates to the same extent that such amount was recognized under the corresponding Seller Plan. With respect to the In-Scope Employees, Buyer and Seller shall cooperate in providing information
reasonably necessary to carry out this Section 8.3 in compliance with the Health Insurance Portability and Accountability Act of 1996.



8.4 Reuters 401(k) Plan. Prior to the Closing Date, the Company shall terminate its participation in the Reuters 401(k) Plan effective immediately
prior to the Closing and shall vest the account balances of those In-Scope Employees who are active participants in the Reuters 401(k) Plan immediately prior to Closing. Within 30 days following the Closing Date, Seller or one of its Affiliates
(other than the Company) shall contribute a cash amount to the trust forming part of the Reuters 401(k) Plan on behalf of each In-Scope Employee who was an active participant in the Reuters 401(k) Plan immediately prior to the Closing equal to the
matching contribution payable for the payroll period in which the Closing occurs under the terms of the Reuters 401(k) Plan with respect to elective deferral contributions actually made by such In-Scope Employee to the Reuters 401(k)
Plan for the portion of the payroll period in which the Closing occurs ending on the Closing Date, to the extent not otherwise paid.



8.5 Buyer 401(k) Plan. To the extent permitted by applicable law and subject to Buyers and Sellers reasonable satisfaction that the
Reuters 401(k) Plan and Buyers 401(k) Plan, respectively, meet the requirements for qualification under Section 401(a) of the Code, (i) Seller shall permit each In-Scope Employee to effect, and Buyer agrees to cause Buyers 401(k) Plan to
accept, a direct rollover (within the meaning of Section 401(a)(31) of the Code) of his or her account balances under the Reuters 401(k) Plan if such rollover is elected in accordance with applicable law and the terms of the Reuters
401(k) Plan by such In-Scope Employee and (ii) Seller shall permit each In-Scope Employee to roll over any loan balance outstanding under the Reuters 401(k) Plan as of the date of such direct rollover and Buyer agrees to accept and administer each
such outstanding loan balance under Buyers 401(k) Plan. Buyer and Seller shall take all actions reasonably necessary to effect the transfer of assets in accordance with the foregoing sentence.



8.6 Medical Plan Obligations. Effective from and after the Closing,
Buyer shall or shall cause the Company to honor or pay and perform any and all obligations and Liabilities in respect of claims for hospital, medical, dental or other health benefits, expenses or other reimbursement amounts payable under the terms
of an applicable Seller Plan that relate to any medical service, product or confinement provided to or in respect of any In-Scope Employee (or spouse or eligible dependent) incurred but not paid prior to the Closing Date to the extent that
Liabilities for such claims are accrued on the Historical Financial Statements for the year ended December 31, 2004 or are incurred and relate to services rendered in the period from January 1,



43



---

2005 to the Closing to the extent such Liabilities are incurred in the ordinary course of business consistent with past practice.



8.7 Parent Equity Plans. Buyer shall promptly notify Parent or
Parents designee of any termination of an In-Scope Employees employment. Buyer shall describe the nature of such termination and provide any other information that is reasonably necessary for Parent and its Affiliates to administer their
respective equity programs.



8.8 Severance Benefits. In
lieu of any other severance plan payments otherwise provided by the Company or the Buyer, and notwithstanding Section 8.2, In-Scope Employees who are terminated by Buyer or the Company without cause (as defined on Schedule 8.8) on or before the
six-month anniversary of the Closing Date will be provided severance payments and benefits by the Buyer or the Company calculated in accordance with Appendix A of the Reuters America Inc. Severance Benefit Plan and Summary Plan Description, as in
effect on May 21, 2001. Thereafter, In-Scope Employees who are terminated by the Company shall be eligible to participate in Buyers severance plans and programs on the same terms available to and subject to the same conditions as similarly
situated employees of Buyer.



8.9 Relocation Package. In
the event that Buyer requires any In-Scope Employee to change his/her principal work location by more than fifty (50) miles at any time during the two-year period following the Closing Date, Buyer shall reimburse such In-Scope Employee for his or
her reasonable moving and relocation expenses.



8.10 2005
Bonus. Buyer shall, or shall cause the Company to, pay to In-Scope Employees short-term (i.e., one (1) year or less) bonuses and commissions for the portion of the calendar year 2005 through the Closing Date to the extent Liability is accrued
for such purpose on the Closing Balance Sheet.



8.11 Special
Payment. Seller or one of its Affiliates (other than the Company) shall pay to the Company a cash amount (the Special Payment), with respect to each In-Scope Employee who is an active participant in the Reuters 401(k) Plan
immediately prior to the Closing and who continues employment with Buyer or the Company from the Closing Date through December 31, 2005 (each, an Affected Employee), equal to 2% of such Affected Employees Compensation (as
defined in the Reuters 401(k) Plan) received in respect of the portion of calendar year 2005 ending immediately prior to the Closing Date, and grossed-up for income taxes assuming a 40% aggregate income tax rate. Buyer shall, or shall cause the
Company to, provide Seller with an accurate list of Affected Employees as promptly as possible following December 31, 2005, in order for Seller to satisfy this Section 8.11. Seller shall pay the Special Payment to the Company as soon as reasonably
practicable following Sellers receipt of the list of Affected Employees from Buyer or the Company, and Buyer shall cause the Company to pay the Special Payment to each Affected Employee as soon as reasonably practicable thereafter.



8.12 No Third-Party Beneficiaries. This Article VIII is for the
sole benefit of the Parties and nothing herein expressed or implied shall give or be construed to give any Person other than the Parties any legal or equitable rights hereunder.

ARTICLE IX



INDEMNIFICATION



9.1 Indemnification by Buyer. From and after the Closing, subject to
the further provisions of this Article IX, Buyer shall indemnify, hold harmless and defend Seller, its Affiliates and their respective directors, officers, employees, consultants, shareholders, members, partners, agents and representatives of each
of them, and all successors and assigns of the foregoing, against and from any Damages (including any Damages resulting from a claim asserted by a third party) arising out of the breach of any representation, warranty, covenant or agreement by Buyer
(other than Section 5.12 (Third Party Data Providers)) contained in this Agreement (including any Exhibit, Schedule or certificate delivered hereunder). The Parties expressly agree that Sellers right to indemnification under this Section 9.1
shall not be limited by any knowledge obtained pursuant to any investigation conducted by or on behalf of Seller before or after the date of this Agreement.



9.2 Indemnification by Seller and Parent.



(a) From and after the Closing, subject to the further provisions of this Article IX, Seller shall indemnify, hold harmless and defend Buyer, its
Affiliates and their respective directors, officers, employees, consultants, shareholders, members, partners, agents and representatives of each of them, and all successors and assigns of the foregoing, against and from any Damages (including any
Damages resulting from a claim asserted by a third party) arising out of the breach of any representation, warranty (other than Section 3.14 (Taxes) or any liability governed by Article X), covenant or agreement by Seller contained in this Agreement
(including any Exhibit, Schedule or certificate delivered hereunder), it being understood that for purposes of this Section 9.2, the knowledge qualifier in the representation in the first sentence of Section 3.11(f) shall be disregarded.



(b) From and after the Closing, subject to the further provisions of this
Article IX, Parent shall indemnify, hold harmless and defend Buyer, its Affiliates and their respective directors, officers, employees, consultants, shareholders, members, partners, agents and representatives of each of them, and all successors and
assigns of the foregoing, against and from any Damages (including any Damages resulting from a claim asserted by a third party) arising out of the breach of any representation, warranty (other than Section 3.14 (Taxes) or any liability governed by
Article X), covenant or agreement by Parent contained in this Agreement (including any Exhibit, Schedule or certificate delivered hereunder).



(c) The Parties expressly agree that Buyers right to indemnification under this Section 9.2 shall not be limited by any knowledge obtained pursuant
to any investigation conducted by or on behalf of Buyer before or after the date of this Agreement.



9.3 Defense of Claims. All rights of a Party to indemnification under this Article IX shall be asserted and resolved as follows:



(a) Promptly after receipt by a Party entitled to indemnification under
Section 9.1 or Section 9.2 (an Indemnified Party) of notice of any pending or threatened claim, such Indemnified Party shall give notice to the Party or Parties to whom the Indemnified Party is entitled to look for indemnification
(the Indemnifying Party) of the commencement thereof;



45



---

provided that the failure so to notify the Indemnifying Party shall not relieve it of any liability that it may have to the Indemnified Party
hereunder, except to the extent that the Indemnifying Party demonstrates that it is materially prejudiced thereby.



(b) In case any claim shall be brought against an Indemnified Party and it shall give notice to the Indemnifying Party of the commencement thereof, 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 this Article IX 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 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, based on an opinion of its outside legal counsel, that there may be legal defenses available to it which are different
from or additional to those available to the Indemnifying Party and would make representation of both parties by the same counsel inappropriate (in which case the Indemnifying Party shall not have the right to assume the defense of such claim on the
Indemnified Partys behalf), (ii) the Indemnifying Party shall have abandoned or failed to diligently pursue the defense of such claim within a reasonable time after notice of the institution of such claim, or (iii) the Indemnifying Party shall
authorize in writing the Indemnified Party to employ separate counsel at the Indemnifying Partys expense. If an Indemnifying Party assumes the defense of a claim, the Indemnified Party shall provide all reasonable cooperation to the
Indemnifying Party in its defense of such claim, including the retention of and provision to the Indemnifying Party of documentation relevant to such claim (including copies of all relevant notices, complaints, pleadings and demands) and, upon the
request of the Indemnifying Party, making employees available on a mutually convenient basis. 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 written consent (which shall not be unreasonably withheld or delayed); provided that the Indemnifying Party may compromise or settle such claim without the Indemnified Partys consent so long as (a) there is a
release of all liability of the Indemnified Party with respect to such claim and (b) the sole relief provided is monetary damages that are to be paid in full by the Indemnifying Party. In no event shall the Indemnified Party admit any liability with
respect to, or settle, compromise or discharge, any claim as to which such Indemnified Party has sought or may seek indemnification under this Agreement without the Indemnifying Partys prior written consent (which shall not be unreasonably
withheld or delayed).



(c) In the event any Indemnified Party
should have a claim against any Indemnifying Party hereunder which does not involve a claim being asserted by a third party, the Indemnified Party shall as promptly as is practical notify the Indemnifying Party of such claim, describing such claim
and the amount thereof (if known). The failure to give any such notice shall not relieve the Indemnifying Party of its obligations hereunder except to the extent that such failure results in material prejudice to the Indemnifying Party. Upon the
giving of such written notice as aforesaid, the Indemnified Party and the Indemnifying Party shall negotiate in



46



---

good faith for twenty (20) Business Days to resolve such claim. If the claim is not resolved by the end of such period, the Indemnified Party shall have the
right to commence legal proceedings for the enforcement of its rights under Section 9.1 or Section 9.2.



9.4 Survival; Subrogation.



(a) Each representation, warranty, agreement and covenant in this Agreement or in the Exhibits, Schedules or certificates delivered pursuant to this
Agreement shall survive the Closing and the consummation of the transactions provided for herein for the applicable period set forth below or in this Section 9.4, or, with respect to Section 3.14(k), 3.14(n) and 3.14(o), for the applicable period
set forth in Section 10.6; provided that the representation set forth in Section 3.4(c) (No Material Adverse Change) and the representations, warranties, agreements or covenants contained in Section 3.14 (Taxes) (other than those
contained in Sections 3.14(k), 3.14(n) and 3.14(o)) shall expire at Closing. All of the representations and warranties of Seller, Parent or Buyer contained in this Agreement and all unasserted claims and causes of action with respect thereto (except
as provided above with respect to Sections 3.4(c) and 3.14) shall terminate twelve (12) months after the Closing Date.



(b) All covenants or agreements of Seller, Parent or Buyer contained in this Agreement and all unasserted claims and causes of action with respect thereto
shall terminate sixty (60) days after the expiration of the applicable statute of limitations (giving effect to any waiver, mitigation or extension thereof).



(c) 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.



9.5 Limitation on Liability.



(a) Except for any liability under Article X and notwithstanding any other provision of this Agreement (other than the last sentence of Section 9.7),
neither Buyer, on the one hand, nor Seller or Parent, on the other hand, shall have any liability for Damages under Sections 9.1 or 9.2, respectively, with respect to any breach of any representation or warranty in this Agreement (other than any
representation or warranty contained in Section 3.15 (Capitalization; Investments), Section 3.17 (Finders and Brokers), Section 3.24 (Exclusive Soft Dollar Customers), Section 4.4 (Finders and Brokers) and Section 4.5 (Valid Authorization and
Issuance)) unless and until the aggregate amount of such Damages exceeds, on a cumulative basis, $600,000, in which event such Indemnified Party shall be entitled to indemnification for the full amount of such Damages in excess of $600,000.



(b) Except for any liability under Article X and
notwithstanding anything in this Agreement to the contrary (other than the last sentence of Section 9.7), neither Buyer, on the one hand, nor Seller or Parent, on the other hand, shall have any liability for Damages (on a cumulative basis) under
Sections 9.1 or 9.2, respectively, in excess of the dollar value of the Purchase Price determined as of the Closing Date.



(c) The amount of any Damages for which indemnification is provided under this Article IX or Article X shall be net of any amounts recovered by the
Indemnified Party or Tax



47



---

Indemnitee under any insurance policies, or recovered under any insurance policies held by the Company at or prior to the Closing, or other sources of
reimbursement received as an offset against such Damages (and no right of subrogation shall accrue to any insurer or third party indemnitor hereunder). If the amount to be netted hereunder from any payment required under this Article IX or Article X
is determined after payment by the Indemnifying Party of any amount otherwise required to be paid to an Indemnified Party or Tax Indemnitee pursuant to this Article IX or Article X the Indemnified Party or Tax Indemnitee shall repay the Indemnifying
Party, promptly after such determination, any amount that the Indemnifying Party would not have had to pay pursuant to this Article IX or Article X, as applicable, had such determination been made at the time of such payment. The amount of any
Damages (including Taxes) for which indemnification is provided under this Article IX or Article X shall be (i) increased to take account of any net Tax cost incurred by the Indemnified Party or Tax Indemnitee arising from the receipt or accrual of
indemnity payments hereunder (grossed up) and (ii) reduced to take account of any net Tax benefit (grossed down) realized by the Indemnified Party or Tax Indemnitee arising from the incurrence or payment of any such Damage or Tax. In computing the
amount of any such Tax cost or Tax benefit, the Indemnified Party or Tax Indemnitee shall be deemed to recognize all other items of income, gain, loss, deduction or credit before recognizing any item arising from the receipt or accrual of any
indemnity payment hereunder or the incurrence or payment of any indemnified Damage or Tax. Any indemnification payment hereunder shall initially be made without regard to this paragraph and shall be increased or reduced to reflect any such net Tax
cost (including gross-up) or net Tax benefit (including gross-down) only after the Indemnified Party or Tax Indemnitee has actually realized such cost or benefit. The parties intend to treat any indemnification payments made under this Article IX or
Article X as an adjustment to the Purchase Price for all Tax purposes, unless a final determination (which shall include the execution of a Form 870-AD or successor form) of an appropriate Authority causes any such payment not to be treated as an
adjustment to the Purchase Price for Tax purposes.



(d)
Notwithstanding anything herein to the contrary, (i) no Person shall be entitled to indemnification by Buyer pursuant to this Agreement with respect to any Damages arising out of a breach of any representation, warranty, covenant or agreement
contained in this Agreement (including any Exhibit, Schedule or certificate delivered hereunder) by Buyer in the event that such breach resulted in the failure of any condition precedent(s) set forth in Section 6.2 and Seller executed a written
waiver of such condition(s) and consummated the Closing, and (ii) no Person shall be entitled to indemnification by Seller or Parent pursuant to this Agreement with respect to any Damages arising out of a breach of any representation, warranty,
covenant or agreement contained in this Agreement (including any Exhibit, Schedule or certificate delivered hereunder) by Seller or Parent in the event that such breach resulted in the failure of any condition(s) precedent set forth in Section 6.1
and Buyer executed a written waiver of such condition(s) and consummated the Closing.



9.6 Indemnification Payments. Any indemnification payments to be made by Seller or Parent pursuant to this Agreement shall be paid only in cash, and any indemnification payments to be made by Buyer pursuant to
this Agreement or amounts payable by Buyer pursuant to Section 10.5(a) shall be paid only in shares of Instinet Common Stock equal to the quotient of (a) the dollar amount of such indemnification payment or such other amounts, divided by (b) the
Average Instinet Share Price determined as of the date of such payment.



48

9.7 Sole and Exclusive Remedy. After the Closing Date, except as otherwise provided in Section
5.12, each Party hereto acknowledges and agrees that such Partys sole and exclusive remedy with respect to Damages and any and all other claims relating to the subject matter of this Agreement and/or the Intellectual Property Transfer
Agreement and the transactions contemplated hereby and thereby shall be in accordance with, and limited by, the indemnification provision set forth in this Article IX and in Article X. Notwithstanding the foregoing, none of the provisions set forth
in this Agreement or in the Intellectual Property Transfer Agreement shall be deemed a waiver by any Party of any right or remedy which such Party may have at law or equity based on another Partys fraudulent acts, nor shall any such provision
limit, or be deemed to limit, the recourse which any such Party may seek with respect to a claim for fraud.



ARTICLE X



TAX MATTERS



10.1 Tax Filings.
Seller shall be responsible for the timely filing of all Tax Returns required by law to be filed by the Company for taxable periods (including any portion thereof) ending on or before the Closing Date (Pre-Closing Tax Period),
including Tax Returns (or, in the case of a consolidated Tax Return, portion thereof) for the Company for any taxable period that includes (but does not end on) the Closing Date, which Tax Returns shall be prepared on the basis of the same
principles, methods and elections utilized in preparing prior years Tax Returns unless a different treatment of any item is required by an intervening change in law. No Tax Return (or, in the case of a consolidated Tax Return, portion thereof)
for the Company for any taxable period that includes (but does not end on) the Closing Date shall be filed without the written consent of Buyer. For this purpose, Seller shall cause the Company to deliver a draft of any such Tax Return (or, in the
case of a consolidated Tax Return, portion thereof) to Buyer at least forty-five (45) days before the due date for such Tax Return. Buyer shall then have thirty (30) days after the date of receipt of such Tax Return to provide its written consent,
which consent shall not be unreasonably withheld. Buyer shall provide Seller with, or shall cause the Company to provide, copies of any books or records necessary for the preparation of any such Tax Returns. Buyer shall be responsible for filing all
Tax Returns for taxable periods commencing after the Closing Date.



10.2 Apportionment of Taxes. Seller shall be responsible for all Taxes in respect of the Company and its business for Pre-Closing Tax Periods, and Buyer shall be responsible for all such Taxes for Post-Closing Tax Periods, it being
understood that Seller and Buyer shall share equal responsibility for any Taxes imposed or payable or collectible or incurred in connection with this Agreement and the transactions contemplated hereby (except Taxes arising out of or attributable to
prior transactions entered into by the Company). For purposes of the foregoing, income and expenses, determined on an accrual basis, shall be allocated between the Pre-Closing Tax Period and the Post-Closing Tax Period based on a
closing-of-the-books method, it being understood that non-income Taxes shall be allocated between the Pre-Closing Tax Period and the Post-Closing Tax Period based on the relative number of days in such taxable period that falls within the
Pre-Closing Tax Period or the Post-Closing Tax Period, as the case may be.

10.3 Tax Indemnification.



(a) Seller shall indemnify and save the Buyer and the Company (each a Tax Indemnitee) harmless from any
and all Taxes imposed on the Company in respect of its income, business, property or operations or for which the Company may otherwise be liable (A) for any Pre-Closing Tax Period, (B) for all Taxes imposed on any member of an affiliated,
consolidated, combined or unitary group of which the Company is or was a member on or prior to the Closing Date, including pursuant to Treasury Regulation Section 1.1502-6 or any analogous or similar state, local or foreign law or regulation, (C)
arising out of a breach of the representations contained in Section 3.14(n) or Section 3.14(o), or (D) for any costs or expenses with respect to Taxes indemnified hereunder; provided, however, that Seller shall not be required to
indemnify Buyer or the Company for any Taxes resulting from any transaction of the Company not in the ordinary course of business (other than the transactions contemplated hereunder) that occurs after the Closing on the Closing Date.



(b) The Buyer and the Company shall indemnify and save Seller and Parent (a
Tax Indemnitee) harmless from (i) all Taxes of the Company in respect of its income, business, property or operations or for which the Company may otherwise be liable (A) resulting from any transaction of the Company not in the
ordinary course of business (other than any transaction contemplated hereunder) occurring after the Closing on the Closing Date and (B) for any Post-Closing Tax Period, (ii) all Taxes arising out of or due to any breach of any covenant or other
agreement of the Buyer contained in this Agreement and (iii) all costs or expenses with respect to Taxes indemnified hereunder.



(c) Any indemnity payment required to be made pursuant to this Section 10.3 shall be made within thirty (30) days of written notice from the Tax
Indemnitee.



10.4 Contests.



(a) After the Closing Date, Buyer shall promptly notify Seller in writing of
any proposed assessment, the commencement of any audit or court proceedings or of any demand or claim on a Tax Indemnitee which, if determined adversely to the taxpayer or after the lapse of time, would be grounds for indemnification by Seller under
Section 10.3 (each such assessment, audit, court proceeding, demand or claim, a Contest); provided that the failure so to notify Seller shall not relieve Seller of any liability that it may have to the Tax Indemnitee
hereunder, except to the extent that Seller demonstrates that it is actually prejudiced thereby. Such notice (a Tax Claim) shall contain factual information (to the extent known to Buyer) describing the asserted Tax liability in
reasonable detail and shall include copies of any notice or other document received from any taxing authority in respect of any such asserted Tax liability.



(b) In the case of any Contest that relates to a taxable period ending on or prior to the Closing Date, Seller shall have the right, at its expense and
through counsel of its own choosing, to control the conduct of such Contest; provided that (i) Seller does not dispute its obligation to indemnify the Tax Indemnitees for the asserted liability, (ii) Seller shall consult with the Buyer
regarding any such Contest and shall allow Buyer to participate in any such proceeding and (iii) no settlement or other disposition of any claim for Tax which would adversely affect any Tax Indemnitee in any taxable period ending after the Closing
Date in any manner or to any extent (including, but not limited to, the imposition of income tax deficiencies, the reduction of asset basis or cost adjustments and the reduction of loss or credit carryovers)

shall be agreed to without Buyers prior written consent, such consent not to be unreasonably withheld or delayed, unless Buyer agrees to indemnify the
Seller for any increase in Taxes resulting from a failure to provide consent. If Seller elects not to direct the Contest, Buyer or the Company may pay, compromise, or contest such asserted liability.



(c) In the case of a Contest that relates to a taxable period beginning
before the Closing Date and ending after the Closing Date, Buyer shall have the right, at its expense and through counsel of its own choosing, to control the conduct of such Contest; provided that (i) Buyer shall consult with Seller regarding
any such Contest and shall allow Seller to participate in any such proceeding and (ii) no settlement or other disposition of any claim for Taxes which would adversely affect Seller in such taxable periods or subsequent taxable periods shall be
agreed to without Sellers prior written consent, such consent not to be unreasonably withheld or delayed, unless Seller agrees to indemnify the Buyer for any increase in Taxes resulting from a failure to provide consent. Except as provided
above, the Buyer shall have the right to control the conduct of any Contest in its sole discretion with respect to any other Tax matter.



(d) Seller, Buyer and the Company agree to cooperate in the defense against or compromise of any Contest.



10.5 Other Tax Matters.



(a) Any Tax refunds that are received by Buyer or its Affiliates (including
the Company) and any amounts credited against Tax to which Buyer or its Affiliates (including the Company) become entitled, in each case with respect to Taxes of the Company, for Pre-Closing Tax Periods shall be for the account of Seller, and Buyer
shall pay over to Seller any such refund or the amount of any such credit within fifteen (15) days after the receipt or entitlement thereto. Buyer agrees that it shall not, without Sellers consent, cause or permit the Company to carry back to
any Pre-Closing Tax Period any net operating loss, loss from operations or other Tax attribute, and further agrees that Seller shall have no obligation under this Agreement to return or remit any refund or other Tax benefit attributable to a breach
by Buyer of the foregoing undertaking.



(b) Buyer shall not
take any action on the Closing Date other than in the ordinary course of business or as contemplated by this Agreement, including, but not limited to, the sale of any assets or the distribution of any dividend or the effectuation of any redemption,
that would give rise to any Tax liability of Seller or any of its Affiliates or to an indemnification obligation of Seller under this Agreement. On or after the Closing Date, neither Buyer nor any of its Affiliates shall amend any Tax Return, take
any Tax position on any Tax Return, or compromise or settle any Tax liability, in each case relating to the Company if such action is reasonably expected to have the effect of increasing the Tax liability or reducing any Tax asset of Seller, in each
case without Sellers written consent, which consent shall not be unreasonably withheld or delayed.



(c) On or after the Closing Date, neither Seller nor any of its Affiliates shall amend any Tax Return, take any Tax position on any Tax Return, or
compromise or settle any Tax liability, in each case if such action is reasonably expected to have the effect of increasing the Tax liability or reducing any Tax asset of the Company, in each case without Buyers written consent, which consent
shall not be unreasonably withheld or delayed.

10.6 Survival. A partys obligation to indemnify a Tax Indemnitee for Taxes under this
Article X shall survive the Closing Date until sixty (60) days following the expiration of the statute of limitations (giving effect to any waiver, mitigation or extension thereof) on assessment of the relevant Tax.



10.7 Exclusive Remedy. Notwithstanding anything to the contrary in
this Agreement, any Tax Claims will be governed exclusively by Section 9.5(c), Section 9.6, Section 9.7 and this Article X.

Section.



11.2 Press Releases. Prior to Closing, neither
Buyer nor Seller shall make any disclosure of this Agreement or the transactions contemplated hereby, by press release, public statement or other means, prior to obtaining the other Parties written approval, unless required by law or any
applicable rules or request of any national stock exchange in which event, the Party issuing such press release or causing such announcement or disclosure will use reasonable efforts to allow the other Parties to review, in advance of such issuance,
announcement or disclosure, the proposed language thereof.

the Parties as to



53

matters covered herein and therein and supersedes any prior understanding, agreement or statement (written or oral) of intent among the Parties with respect
to the subject matter hereof.



11.4 Assignability. This
Agreement shall be binding upon and inure to the benefit of the Parties and their respective successors and permitted assigns. This Agreement shall not be assignable by any Party without the prior written consent of the other Parties;
provided, however, that any Party may assign all or a part of its rights hereunder to any of its respective Affiliates provided that such assignment would not relieve such Party of any obligation hereunder.



11.5 Waiver and Amendment. No waiver shall be deemed to have been made
by any Party of any of its rights under this Agreement unless the same is in writing and is signed on its behalf by an authorized signatory. Any such waiver shall constitute a waiver only with respect to the specific matter described in such writing
and shall in no way impair the rights of the Party granting such waiver in any other respect or at any other time. To be binding, any amendment of this Agreement must be effected by an instrument in writing signed by the Parties.



11.6 Expenses. Each of the Parties shall bear its own expenses in
connection with this Agreement and the transactions contemplated hereby, whether or not the Closing occurs.



11.7 Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original and all of which
together shall be deemed to be one and the same instrument.



11.8 Governing Law; Submission to Jurisdiction; Appointment of Agent for Service of Process; Waiver of Jury Trial.



(a) THE AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. Each Party hereby irrevocably agrees that any
legal action or proceeding against it arising out of this Agreement or the transactions contemplated hereby shall be brought only in the Supreme Court of the State of New York in and for the County of New York or the U.S. District Court for the
Southern District of New York, preserving, however, all rights of removal to a federal court under 28 U.S.C. §1441. Each of Seller and Parent hereby designates, appoints and empowers Reuters America Holdings, Inc., with offices currently at 3
Times Square, New York, New York 10036, as its lawful agent to receive for and on its behalf service of process in the State of New York in any such action or proceeding and irrevocably consents to the service of process outside the territorial
jurisdiction of said courts in any such action or proceeding by mailing copies thereof by registered United States mail, postage prepaid, to its address as specified in or pursuant to Section 11.1. Any service made on any such agent or its successor
shall be effective when delivered regardless of whether notice thereof is given to the affected Party. If any Person or firm designated as agent hereunder shall no longer serve as agent of such Party to receive service of process in the State of New
York, the Party so affected shall be obligated promptly to appoint a successor to so serve; and, unless and until such successor is appointed and the other Parties notified of the same in writing, service upon the last designated agent shall be good
and effective. Each of Seller and Parent hereby agrees to at all times maintain an agent to receive service of process in the State of New York pursuant to this Section 11.8. The foregoing



54



---

provisions of this Section 11.8 shall not affect, limit or prevent the Parties from serving process in any other manner permitted by law.



(b) Each Party irrevocably waives any objection to the venue of the courts
designated in Section 11.8 (whether on the basis of forum non conveniens or otherwise), and accepts and submits to the jurisdiction of such courts in connection with any legal action or proceeding against it arising out of or concerning this
Agreement.



(c) EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY
WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATED TO THIS AGREEMENT, THE RELATED AGREEMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.



11.9 No Third-Party Beneficiaries. Except for Section 5.10 (with respect to which the Company shall be a third-party
beneficiary), this Agreement is for the sole benefit of the Parties and nothing herein expressed or implied shall give or be construed to give any Person other than the Parties any legal or equitable rights hereunder.



11.10 Severability. If any term or other provision of this Agreement
is invalid, illegal or incapable of being enforced by any rule of law, or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the
transactions contemplated hereby is not affected in any manner adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to
modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner to the end that transactions contemplated hereby are fulfilled to the extent possible.



11.11 Disclosure Schedules. Notwithstanding anything in this Agreement
or the Disclosure Schedules to the contrary, (i) each of the Parties hereto acknowledges that the disclosure by any Party of any matter in the Disclosure Schedules shall not be deemed to constitute an acknowledgement by such Party that the matter is
required to be disclosed by the terms of this Agreement or that it is material and (ii) if any Section of the Disclosure Schedule includes an item or information where the relevance of such item or information to another Section of this Agreement or
the Disclosure Schedule is reasonably apparent, the matter shall be deemed to have been disclosed in the relevant Section(s) of the Disclosure Schedule, notwithstanding the omission of an appropriate cross-reference to such other Section(s).
