INVESTMENT TECHNOLOGY GROUP, INC.

STOCK UNIT GRANT AGREEMENT

FOR EMPLOYEES

THIS GRANT AGREEMENT, dated as of                   (the “Date of Grant”), is entered into by and between Investment Technology Group, Inc. (the “Company”), a Delaware corporation, and                , an employee of the Company (the “Employee”).

WHEREAS, the Employee has been awarded the following Grant under the Investment Technology Group, Inc. 2007 Omnibus Equity Compensation Plan (the “Plan”).  Capitalized terms used herein and not defined herein shall have the meanings set forth in the Plan.  In the event of any conflict between this Grant Agreement and the Plan, the Plan shall control.

NOW, THEREFORE, in consideration of the premises and mutual covenants contained herein, and for other good and valuable consideration, the parties hereto agree as follows:

1.             Grant of Stock Units.  Subject to the terms and conditions set forth in this Grant Agreement and the Plan, the Employee is hereby awarded             Stock Units that represent hypothetical shares of Company Stock on a one-for-one basis (the “Stock Unit Grant”).

2.             Grant Subject to Plan Provisions.  This Stock Unit Grant is granted pursuant to the Plan, the terms of which are incorporated herein by reference, and in all respects shall be interpreted in accordance with the Plan.  The Plan and the Plan prospectus are available at http://assetlib.itginc.com/stellent/groups/public/documents/itginc/047794.pdf and http://assetlib.itginc.com/stellent/groups/public/documents/itginc/047867.pdf, respectively; provided that paper copies of the Plan and the Plan prospectus are available upon request by contacting the Legal Department of the Company at ITG_Legal or ###-###-####.  This Stock Unit Grant is subject to interpretations, regulations and determinations concerning the Plan established from time to time by the Committee in accordance with the provisions of the Plan, including, but not limited to, provisions pertaining to (a) the registration, qualification or listing of the shares issued under the Plan, (b) changes in capitalization, (c) requirements of applicable law and (d) all other Plan provisions.  The Committee has the authority to interpret and construe this Grant Agreement pursuant to the terms of the Plan, and its decisions are conclusive as to any questions arising hereunder.

3.             Stock Unit Account.  The Company shall establish and maintain a Stock Unit bookkeeping account (the “Account”) on its records for the Employee and shall record in the Account the number of Stock Units awarded to the Employee.  No shares of stock shall be issued to the Employee at the time the Stock Unit Grant is made.

4.             Vesting of the Stock Unit Grant.

(a)     Subject to Section 5 below and the other terms and conditions of this Grant Agreement and the Plan, this Stock Unit Grant shall become vested in full and all restrictions on the Stock Unit Grant shall lapse on the third anniversary of the Date of Grant if the Employee has remained continuously employed by the Employer from the Date of Grant through the vesting date; provided, however, that the Stock Unit Grant shall become immediately

vested in full (i) upon a Change in Control if the Employee is employed by the Employer as of the date of the Change in Control or (ii) upon the Employee’s Termination of Service (as defined below) due to the Employee’s death or Disability (as defined below).

“Disability” shall have the meaning ascribed to such term in Section 22(e)(3) of the Code.

(b)     Unless otherwise provided by the Committee, all amounts receivable in connection with any adjustments to the Company Stock under Section 5(d) of the Plan shall be subject to the vesting schedule in this Section 4.

5.             Termination of Service; Forfeiture of Unvested Stock Unit Grant.  In the event of the Employee’s Termination of Service for any reason other than due to the Employee’s death or Disability prior to the date the Stock Unit Grant otherwise becomes vested in accordance with Section 4 above, the Stock Unit Grant shall immediately be forfeited by the Employee.

“Termination of Service” means the Employee ceases to be employed by the Employer.  An Employee employed by a Subsidiary of the Company shall also be deemed to incur a Termination of Service if such Subsidiary ceases to be a Subsidiary of the Company and such Employee does not immediately thereafter become employed by the Company or another Subsidiary of the Company.  Temporary absences from employment because of illness, vacation or leave of absence and transfers among Employers shall not be considered a Termination of Service.

6.             Distribution of Shares.  The Company shall distribute to the Employee (or the Employee’s heirs in the event of the Employee’s death) at the time of vesting of the Stock Unit Grant in accordance with Section 4 above (but not later than March 15 of the calendar year following the calendar year in which the Stock Units vest), a number of shares of Company Stock equal to the number of Stock Units then held by the Employee that became vested at such time, subject to reduction for withholding of shares pursuant to Section 9 below.

7.             Rights and Restrictions.  The Stock Unit Grant shall not be transferable, other than by will or under the laws of descent and distribution (or pursuant to a beneficiary designation authorized by the Committee).  Prior to vesting of the Stock Unit Grant and delivery of the shares of Company Stock to the Employee, the Employee shall not have any rights or privileges of a stockholder as to the shares of Company Stock subject to the Stock Unit Grant.  Specifically, the Employee shall not have the right to receive dividends or the right to vote such shares of Company Stock, nor shall the Employee have the right to sell, assign, pledge, hypothecate, encumber, transfer or otherwise dispose of, in whole or in part, the Stock Unit Grant, prior to vesting of the Stock Unit Grant and delivery of the shares of Company Stock.  The Employee shall not have any interest in any fund or specific assets of the Employer by reason of this Stock Unit Grant or the Account established for the Employee.

8.             Limitations.  Nothing herein shall limit the Company’s right to issue Company Stock, or Stock Units or other rights to purchase Company Stock subject to vesting, expiration and other terms and conditions deemed appropriate by the Company and its affiliates.  Nothing expressed or implied herein is intended or shall be construed to confer upon or give to

2

any Person, other than the parties hereto, any right, remedy or claim under or by reason of this Grant Agreement or of any term, covenant or condition hereof.

9.             Withholding.  The Employee shall pay to the Employer or make arrangements satisfactory to the Committee regarding payment of any federal, state or local taxes of any kind required by law to be withheld at any time with respect to the Stock Unit Grant and the Employer shall, to the extent permitted or required by law, have the right to deduct from any payment of any kind otherwise due to the Employee, federal, state and local taxes of any kind required by law to be withheld.  To the extent permitted by the Committee, the Employee may elect to have the Employer withhold Company Stock to pay any applicable withholding taxes resulting from the Stock Unit Grant, in accordance with any rules or regulations of the Committee then in effect.

10.           Expenses of Issuance of Company Stock.  The issuance of stock certificates hereunder shall be without charge to the Employee.  The Company shall pay, and indemnify the Employee from and against any issuance, stamp or documentary taxes (other than transfer taxes) or charges imposed by any governmental body, agency or official (other than income taxes) by reason of the issuance of Company Stock.

11.           Terms are Binding.  The terms of this Grant Agreement shall be binding upon the executors, administrators, heirs, successors, transferees and assignees of the Employee and the Company.

13.           References.  References herein to rights and obligations of the Employee shall apply, where appropriate, to the Employee’s legal representative or estate without regard to whether specific reference to such legal representative or estate is contained in a particular provision of this Grant Agreement.

14.           Notices.  Any notice required or permitted to be given under this Grant Agreement shall be in writing and shall be deemed to have been given when delivered personally or by courier, or sent by certified or registered mail, postage prepaid, return receipt requested, duly addressed to the party concerned at the address indicated below or to such changed address as such party may subsequently, by similar process, give notice of:
