The Class A Unit Holders shall use their reasonable best efforts to reach an agreement with the Trader Group (x) establishing, in accordance with the Tag-Along Agreement or by agreement with the Trader Group, the fair market value of the Houston Interests and (y) providing that the purchase of the Houston Interests by either ProTrader LP or the Class A Unit Holders, at Buyer's election, shall satisfy ProTrader LP's obligations to cause Buyer to purchase the Houston Interests pursuant to the Tag-Along Agreement. To assist the Class A Unit Holders in their obligations hereunder, no later than 15 Business Days following delivery to Buyer of all of the historical financial, trade accounts and other information in the possession of the Class A Unit Holders with respect to the Houston OSJ, Buyer shall provide the Class A Unit Holders in writing the price at which Buyer would be willing to either (i) purchase the Houston Interests or (ii) sell ProTrader LP's interest in the Houston OSJ to the Trader Group or Sellers.

If Buyer elects not to exercise its right to purchase, or have ProTrader LP purchase, the Houston Interests, the Houston Interests Purchase Price shall be paid by Sellers. (c) If Buyer elects to purchase, or to have ProTrader LP purchase, the Houston Interests, Buyer shall use its reasonable best efforts to close such purchase as promptly as practicable after such election but in no event earlier than the Closing Date. 5.8 Transfer Restrictions.

Without limiting the foregoing, each Seller agrees not to take any action during the period referred to in the immediately prior sentence with the intent of effecting the Instinet Share Price. 5.9 Tampa Office. The Class A Unit Holders acknowledge that the transactions contemplated in this Agreement may give rise to an obligation on the part of PROTRADER Capital LP to establish an irrevocable letter of credit in support of PROTRADER Capital LP's obligation to make a payment of $1,250,000 to Matthew W. Ryan, Gale Kirkpatrick, Francis Hoar, Peter Hoar, Kevin McGinnis and Brian Groh (the "Tampa Sellers") pursuant to Section 1.2(a)(ii) of the Stock Purchase Agreement dated May 11, 2001 by and among PROTRADER Capital LP, ProTrader LP, PROTRADER SECURITIES CORPORATION and the Tampa Sellers (the "Tampa Stock Purchase Agreement"). The Class A Unit Holders shall use reasonable efforts to cause the Tampa Sellers to agree to accept in lieu of such letter of credit the express assumption by ProTrader LP of PROTRADER Capital LP's obligations in connection with PROTRADER Capital LP's obligation to make such $1,250,000 payment. If the Tampa Sellers elect to cause PROTRADER Capital LP to provide the Tampa Sellers with an irrevocable letter of credit, the Class A Unit Holders agree that the Class A Unit Holders shall pay PROTRADER Capital LP's share, as set forth in the Tampa Stock Purchase Agreement, of any costs, expenses and fees incurred in connection with the preparation and maintenance of such letter of credit. 5.10 Certain Contingent Liabilities.

(a) Each of Burch, Jamail and Overunder agrees that from and after the Closing, for a period of three years, and each of the Sellers other than Burch, Jamail and Overunder agrees that from and after the Closing, for a period of two years, neither it nor its Affiliates shall, directly or indirectly (including, without limitation, by the ownership of equity, interests in another Person), in any manner or capacity, participate, engage or invest in any business which, as part of its operations, competes in any manner with the business of ProTrader LP Group as currently conducted; provided that nothing in this Agreement shall prohibit Sellers from owning, directly or indirectly, securities of any Person traded on a national securities exchange or listed on the Nasdaq National Stock Market not to exceed 5% of the total amount outstanding of such securities. (b) For a period of two years after the Closing, Sellers shall not, and shall cause each of their Affiliates not to, directly or indirectly, (i) employ or attempt to employ or solicit for employment any employee of ProTrader LP or any of its Subsidiaries or (ii) induce or attempt to influence any employee of ProTrader LP or any of its Subsidiaries to terminate such employee's employment with ProTrader LP or its Subsidiary. The foregoing shall not be violated if the employee in question has been terminated by ProTrader LP or any of its Subsidiaries. In addition, nothing in this Agreement shall prohibit the solicitation or hiring by any of Sellers or their respective Affiliates of any Persons who are to be employees of ProTrader Trading LLC or ProTrader Equity Partners Limited Partnership immediately after the Closing. (c) Because the remedy at law for any breach of the provisions of this Section 5.11 may be inadequate, Sellers consent to the seeking from an appropriate court of an injunction or other equitable relief, without the necessity of actual monetary loss being proved, in order that any breach or threatened breach of this Section 5.11 may be effectively restrained. (d) Effective as of the Closing, (i) Section 16.1 and Article 12 of the ProTrader LP Partnership Agreement and Section 16.1 of the ProTrader LLC Limited Liability Company Agreement, (ii) any other restrictions on competition applicable to Sellers contained in any ProTrader Constituent Documents and (iii) any other non competition agreement in effect immediately prior to Closing by and between any of Burch, Jamail, Kershner and Overunder, on the one hand, and any member of ProTrader Group, on the other hand, shall terminate and have no force and effect as to Sellers.

With respect to each Buyer Plan providing medical, dental, pharmaceutical and/or vision benefits to any ProTrader Employee, Buyer shall cause the pre-existing condition exclusions of such Buyer Plans to be waived for such employee and his or her eligible dependents for those pre-existing conditions of such employee or dependant that would have been covered under the comparable Plan in which such employee was a participant immediately prior to the Closing and Buyer shall cause any eligible expenses incurred by such employee and his or her eligible dependents during the portion of the plan year of the Plan ending on the date such employee's participation in the corresponding Buyer Plans commences to be taken into account under such Buyer Plan for purposes of satisfying all deductible, coinsurance and maximum out-of-pocket requirements 53 applicable to such employee and his or her eligible dependents for the applicable plan year as if such amounts had been paid in accordance with such Buyer Plan. (b) Nothing in this Agreement shall be interpreted as limiting the power of Buyer to amend or terminate any particular Plan or Buyer Plan or any other particular employee benefit plan, program, agreement or policy or as requiring the Buyer to offer to continue the employment of any employee. 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 Sellers, their 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 (i) out of the breach of any representation, warranty, covenant or agreement by Buyer contained in this Agreement (including any Exhibit, Schedule or certificate delivered hereunder) and (ii) any claim by any Person listed on Schedule 8.1 that the consideration to be paid to such Person in accordance with Schedule 8.1 is insufficient to satisfy ProTrader LP's obligations to such Person under the Unit Option Plan with respect to such Person's unvested Options listed on Schedule 8.1. 9.2 Indemnification by Sellers and Young. From and after the Closing, subject to the further provisions of this Article IX, Sellers and, solely with respect to clause (iii) of this Section 9.2, Young shall, jointly and severally, 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 (i) 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 Sellers contained in this Agreement (including any Exhibit, Schedule or certificate delivered hereunder but excluding any representation, warranty, covenant or agreement contained in Article IIIA), (ii) any Proprietary Trading Business Liabilities, (iii) any Damages resulting from any claims by any members of the Trader Group in connection with the Tag-Along Agreement, including any Damages related to the Closing's occurring before the closing under the Tag-Along Agreement, (iv) any Damages resulting from any claims asserted by any equity holders or option holders of ProTrader LP or ProTrader LLC (other than Jamail, Burch and Overunder) in connection with the transfer of the Proprietary Trading Business, (v) any damages arising out of a breach of any ProTrader Constituent Document on or prior to the Closing and (vi) any Damages arising out of any claims by holders of vested Options that such Options were not settled and cancelled in accordance with the Unit Option Plan. The Parties expressly agree that Buyer's right to indemnification under Sections 9.2 and 9.3 shall not be limited by any knowledge obtained pursuant to any due diligence investigation conducted by or on behalf of Buyer. 54 9.3 Additional Indemnification by Sellers. From and after the Closing, subject to the further provisions of this Article IX, each Seller shall severally, and not jointly, 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, covenant or agreement by such Seller contained in Article IIIA of this Agreement. 9.4 Consequential Damages. Except as provided in the following sentence and the last sentence of Section 9.10, in no event shall any Party be responsible for (whether pursuant to Section 9.1 or Section 9.2 or otherwise) any incidental, consequential, indirect, special or punitive damages. However, any indemnity pursuant to Section 9.1, Section 9.2 or Section 9.3 shall include any such incidental, consequential, indirect, special or punitive damages recovered by any third party pursuant to a claim against an Indemnified Party (as defined below). 9.5 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; 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 actually 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 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 authorize the Indemnified Party to employ 55 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 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. (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, the amount thereof (if known) and the method of computation of the amount of the claim, all with reasonable particularity. 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 actual prejudice to the Indemnifying Party. Upon the giving of such written notice as aforesaid, the Indemnified Party shall have the right to commence legal proceedings for the enforcement of their rights under Section 9.1, Section 9.2 or Section 9.3. 9.6 Coordination of Indemnification Rights. In the event a claim is brought by a third party in which the Liability as between the Parties is alleged to be joint or in which the entitlement to indemnification under this Article IX has not been determined, the Parties shall cooperate in the joint defense of such claim and shall offer to each other such assistance as may reasonably be requested in order to ensure the proper and adequate defense of such claim. Such joint defense shall be under the general management and supervision of the Party which is expected to ultimately bear the greater share of the Liability, unless otherwise agreed; provided, however, that no Party shall settle or compromise any such claim without the written consent of the other Party. Any uninsured costs of such joint defense shall be borne as the Parties may agree; provided that in the absence of such agreement, defense costs shall be borne by the Party incurring such costs, subject to any rights to indemnification of such Party under this Article IX. 9.7 Survival of Representations and Warranties; Subrogation. (a) Notwithstanding any investigation conducted or notice or knowledge obtained by or on behalf of a Party, each representation, warranty, agreement and covenant in this Agreement or any of the Related Agreements or in the Exhibits, Schedules or certificates delivered pursuant to this Agreement or any of the Related Agreements which is not by its terms required to be fully performed, or does not by its terms expire, at or prior to the Closing shall survive the Closing and the consummation of the transactions provided for herein for the applicable period set forth in this Section 9.7. All of the representations and warranties of Sellers and Buyer contained in this Agreement and all unasserted claims and causes of action with respect thereto shall terminate upon the first anniversary of the Closing Date, except that the representations and warranties in Section 3.3(ii) (Absence of Conflicts with constituent documents), Sections 3.10 and 3.20 (Regulatory), Section 3.15 (Taxes) and Section 3.17 (Environmental Matters) shall terminate upon the expiration of the applicable statute of limitations. (b) 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 56 Indemnifying Party shall, to the extent of such payment, be subrogated to such rights of such Indemnified Party. 9.8 Limitation on Liability. (a) (i) Notwithstanding any other provision of this Agreement (other than the last sentence of Section 9.10), neither Buyer nor Sellers shall have any liability for Damages under Sections 9.1, 9.2 or 9.3, respectively, or otherwise with respect to any breach of any representation or warranty except to the extent that the aggregate amount of such Damages exceeds, on a cumulative basis, $1,500,000; provided that neither Buyer nor Sellers shall be allocated liability for claims that do not exceed $10,000 for each independent claim or series of related claims (including, to the extent applicable, any claims brought by one Party against another after the $1,500,000 has be reached); provided further that (A) with respect to any breach of any representation or warranty contained in Section 3.4(e) (Net Capital) or Section 3.4(f) (Redemption Obligation Amount) or with respect to any payment owed under Section 2.5(d), no such thresholds shall apply, (B) any claims by Buyer with respect to items for which portions of the Purchase Price have been escrowed pursuant to Sections 2.4(b), 2.4(c) and 2.4(d) shall not be considered in determining the thresholds in this Section 9.8(a) and no such threshold shall apply to such claims and (C) the limitations set forth in this Section 9.8(a)(i) shall not apply to any breach of any covenant or other agreement contained in this Agreement. In the event that a Party brings a claim for an amount in excess of $1,500,000 (subject to the first proviso of the first sentence of this Section 9.8(a)(i)), such Party shall be entitled to indemnification for the full amount of all indemnified Damages (and, for avoidance of doubt, Buyer and Sellers shall be allocated liability for any independent or series of related claims exceeding $10,000). (ii) Notwithstanding anything in this Agreement to the contrary (other than the last sentence of Section 9.10), Sellers, on the one hand, and Buyer, on the other, shall not have any liability to the other for Damages (on a cumulative basis), whether pursuant to the indemnification provisions hereof or otherwise, for any breach of any representations or warranties in excess of the Maximum Indemnification Amount; provided that amounts paid to Buyer from the escrow accounts maintained pursuant to Section 2.4(b), Section 2.4(c) and Section 2.4(d) shall not be subject to, nor count towards, such $50,000,000 limit and such limit shall not apply to any breach of any covenant or other agreement contained in this Agreement. The Maximum Indemnification Amount shall be $50,000,000 (fifty million dollars); provided that, if the Indemnity Escrow Value is less than $50,000,000 (fifty million dollars), the Maximum Indemnification Amount shall be an amount equal to the sum of (A) one-half of the difference between $50,000,000 and the Indemnity Escrow Value and (B) the Indemnity Escrow Value. The Indemnity Escrow Value shall equal the sum of the number of shares of Instinet Common Stock placed in the Indemnification Escrow Account at the Closing multiplied by the Instinet Share Price determined as of the day immediately following the seventh Nasdaq trading day of January 2002. (iii) Buyer shall have no indemnification obligation for any breach of a representation or warranty at any time that the price per share of Instinet Common Stock, 57 as determined by the closing price on NASDAQ (or, if the Instinet Common Stock is then listed on the New York Stock Exchange, the closing price on the New York Stock Exchange) on the date on which a Seller makes a claim pursuant to Section 9.5, is greater than the Instinet Share Price as determined as of the Closing Date. (b) The amount of any Damages for which indemnification is provided under this Article IX shall be net of any amounts recovered by the Indemnified Party under any insurance policies 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 is determined after payment by the Indemnifying Party of any amount otherwise required to be paid to an Indemnified Party pursuant to this Article IX, the Indemnified Party 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 had such determination been made at the time of such payment. 9.9 Method of Satisfying Claims. In addition to any other right or means Buyer may have to enforce the indemnification provided for in Section 9.2, Buyer shall be entitled to make a claim against the funds held in the escrow pursuant to the Escrow Agreement for any amount payable to it pursuant to this Article IX, provided that Sellers' indemnification obligation with respect to Damages arising out of the subject matter of Section 5.10 shall be limited to the Contingency Escrow Amount. Each Seller may, at its option, satisfy any claim for indemnification for breach of representation and warranty against such Seller arising under this Article IX in (i) cash or (ii) property then held in escrow pursuant to the Escrow Agreement (or any combination of (i) and (ii)). Upon satisfaction by an Seller of a claim for breach of representation and warranty other than by a release of cash or Instinet Common Stock from the Escrow Account, an equivalent amount of the cash or Instinet Common Stock of such Seller shall be released from escrow under the Escrow Agreement in accordance with Section 2.4. 9.10 Sole and Exclusive Remedy. After the Closing Date, 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 the transactions contemplated hereby shall be in accordance with, and limited by, the indemnification provision set forth in this Article IX. Notwithstanding the foregoing, none of the provisions set forth in this Agreement shall be deemed a waiver by any party to this Agreement of any right or remedy which such party may have at law or equity based on the other party's fraudulent acts or omissions, 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 Section 754 Election. Each member of ProTrader Group that is a partnership for U.S. federal income tax purposes shall have made the election pursuant to Code section 754, which election shall remain in effect for the taxable year that includes the Closing Date. If the election pursuant to Code section 754 is not in effect as of the date hereof in respect 58 of any member of ProTrader Group that is a partnership for U.S. federal income tax purposes, Sellers hereby agree to cause that member to make such election, effective for the taxable year that includes the Closing Date. Sellers also agree to make, or refrain from making, any other applicable Tax election in respect of ProTrader LP, ProTrader LLC or any of their Subsidiaries, as requested by Buyer, for the taxable year that includes the Closing Date. 10.2 Tax Filings.

No Tax Return for ProTrader LP, ProTrader LLC or any of their Subsidiaries for any taxable period that includes the Closing Date shall be filed without the written consent of Buyer. For this purpose, Sellers shall cause ProTrader LP, ProTrader LLC or any of their Subsidiaries, as the case may be, to deliver a draft of any such Tax Return to Buyer at least 45 days before the due date for such Tax Return. Buyer shall then have 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 Sellers with, or shall cause ProTrader LP, ProTrader LLC or their Subsidiaries, as the case may be, 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 (including any portion thereof) commencing after the Closing Date ("Post-Closing Period"). 10.3 Taxes. Sellers shall be responsible for all Taxes in respect of ProTrader LP, ProTrader LLC or their Subsidiaries, and their respective businesses, for Pre-Closing Periods, and Buyer shall be responsible for all such Taxes for Post-Closing Periods, it being understood that Sellers shall be responsible for any Taxes imposed in respect of the transfers contemplated by this Agreement. For purposes of the foregoing, income and expenses, determined on an accrual basis, shall be allocated between the Pre-Closing Period and the Post-Closing Period based on a closing-of-the-books method, it being understood that non-income Taxes shall be allocated between the Pre-Closing Period and the Post-Closing Period based on the relative number of days in such taxable period that falls within the Pre-Closing Period or the Post-Closing Period, as the case may be.
