Investment Technology Group, Inc. (the “Company”) established the Investment Technology Group, Inc.

The purpose of the Program is to provide an additional incentive to selected members of senior management and key employees to increase the success of the Company, by automatically substituting stock units for a portion of the variable compensation to be earned by such persons, which stock units represent an equity interest in the Company to be acquired and held under the Program on a long-term, tax-deferred basis and to otherwise promote the purposes of the Plan.

4.                                      Stock Subject to the Program

A Participant’s Variable Compensation to be earned for each calendar year of participation shall be automatically reduced by the Actual Reduction Amount.  In no event will the Actual Reduction Amount for any Participant with respect to any calendar year exceed the amount of the Participant’s Variable Compensation for the applicable calendar year.

6.                                      Grant of Stock Units

(a)                                Automatic Grant of Stock Units.  Each Participant shall be automatically granted Basic Units on the date the year end Variable Compensation would otherwise be paid to the Participant in cash (the “Date of Grant”), in a number equal to the Participant’s Actual Reduction Amount divided by the Fair Market Value of a share of Company Stock on such Date.  In addition, unless the Committee determines otherwise, each Participant shall be automatically granted Matching Units on the Date of Grant, in a number equal to 10% of the number of Basic Units granted under this Section 6(a) as of the Date of Grant.  With respect to any Participant paid in foreign currency, the number of Basic Units and Matching Units granted to any such Participant shall be based on such exchange rate as the Company reasonably determines.  All Stock Units shall be credited to Participants on the Date of Grant.

(b)                                Discretionary Grants.  Notwithstanding any provision of the Program or the Plan to the contrary, the Committee may determine, in its sole discretion, to grant stock options representing a number of shares of Company Stock with a Black Scholes value equal to the Actual Reduction Amount, based on the current Fair Market Value of a share of Company Stock on the Date of Grant, in accordance with, and subject to, such terms and conditions as the Committee deems appropriate.  Furthermore, notwithstanding any provision of the Program or the Plan to the contrary, the Committee may determine, in its sole discretion, to award Stock Units to any Participant at such time or times and subject to such terms and conditions as the Committee deems appropriate.

(c)                                 Vesting; Risk of Forfeiture; Cancellation of Certain Stock Units.

(i)                                  Unless the Committee determines otherwise, Basic Units shall vest in equal annual installments on each of the first, second and third anniversaries of the Date of Grant, if the Participant remains continuously employed by the Company or its Subsidiaries on each applicable vesting date.  Unless the Committee determines otherwise, Matching Units shall vest 100% on the third anniversary of the Date of Grant, if the Participant remains continuously employed by the Company or its Subsidiaries through such vesting date.  Except as provided in clauses (ii) through (iv) below, if the Participant’s employment with the Company or its Subsidiaries terminates for any reason prior to a vesting date, unless the Committee provides otherwise, all unvested Basic Units and Matching Units shall be forfeited to the Company.  Basic Units and Matching Units that vest pursuant to this Section 6(c)(i) shall be settled on the schedule set forth in Section 7(a) below.  Performance-Based Units will vest in accordance with the terms specified by the Committee with respect to an individual grant hereunder.

(ii)                               Notwithstanding any provision of the Program to the contrary, all Basic Units and Matching Units that are not Performance-Based Units shall vest in full and all Performance-Based Units shall vest as if target performance had been achieved at 100%, in each case, at the time a Participant’s employment terminates due to his or her death or Disability, and all Basic Units and Matching Units held by such Participant shall be settled within 60 days thereafter.

(iii)                            Notwithstanding any provision of the Program to the contrary, if a Participant’s employment is terminated on account of Retirement or by the Company or one of its Subsidiaries for any reason other than Cause (but not on account of death or Disability), the Committee may, in its sole discretion, determine that, subject to the Participant’s execution and non-revocation of a written release of any and all claims against the Company and all related parties and an agreement containing confidentiality, non-competition, non-solicitation, invention assignment covenants and/or such other restrictions as the Committee determines, on a case-by-case basis at the time of the Participant’s termination of employment, in each case in a form acceptable to the Company, in its sole discretion,

3

the Participant shall continue to vest in all Basic Units and Matching Units as if the Participant continued in employment with the Company or its Subsidiaries on each applicable vesting date and the Basic Units and Matching Units shall be settled on the schedule set forth in Section 7(a) below; provided that any such arrangement shall be structured in a manner that complies with the applicable requirements of section 409A of the Code.  Notwithstanding any provision of this Section 6(c)(iii) to the contrary, the Committee shall be permitted to delegate its authority under this Section 6(c)(iii) to the Administrator as it deems appropriate.

(iv)                           Notwithstanding any provision of the Program to the contrary, all Basic Units and Matching Units that are not Performance-Based Units shall vest in full, and all Performance-Based Units shall vest in full based on the greater of (i) the Company’s actual performance level achieved with respect to the performance goals as of the occurrence of the Change in Control, or (ii) the target performance level as to the performance goals, in either case, upon the occurrence of a Change in Control, if the Participant is employed by the Company or its Subsidiaries on the date of the Change in Control, and in such event the Basic Units and Matching Units shall be settled within 30 days following the Change in Control.

(d)                                Nontransferability.  Stock Units and all rights relating thereto shall not be transferable or assignable by a Participant, other than by will or the laws of descent and distribution, and shall not be pledged, hypothecated, or otherwise encumbered in any way or subject to execution, attachment, or similar process.

(e)                                 Dividend Equivalents on Basic Units.  Dividend Equivalents shall be credited on Basic Units in the manner set forth below for any awards granted hereunder prior to May 19, 2015.  Unless the Committee determines otherwise, no Dividend Equivalent Rights shall be credited on any Basic Units granted hereunder on or after May 19, 2015.  In no event shall Dividend Equivalents be credited with respect to Matching Units.

(i)                                  Cash and Non-Company Stock Dividends.  If the Company declares and pays a dividend or distribution on Company Stock in the form of cash or property other than shares of Company Stock, then a number of additional Stock Units shall be credited to each Participant as of the payment date for such dividend or distribution equal to (A) the number of Basic Units credited to the Participant as of the record date for such dividend or distribution multiplied by (B) the amount of cash plus the fair market value of any property other than shares actually paid as a dividend or distribution on each outstanding share of Company Stock at such payment date, divided by (C) the Fair Market Value of a share of Company Stock at such payment date.  Any such additional Stock Units credited to a Participant hereunder shall vest according to the same schedule as the underlying Basic Units to which they relate and shall be settled in accordance with the applicable provisions of the Program.

(ii)                               Company Stock Dividends and Splits.  If the Company declares and pays a dividend or distribution on Company Stock in the form of additional shares of Company Stock, or there occurs a forward split of Company Stock, then a number of additional Stock Units shall be credited to each Participant as of the payment date for such dividend or distribution or forward split equal to (A) the number of Basic Units credited to the Participant as of the record date for such dividend or distribution or split multiplied by (B) the number of additional shares of Company Stock actually paid as a dividend or distribution or issued in such split in respect of each outstanding share of Company Stock.  Any such additional Stock Units credited to a Participant hereunder shall vest according to the same schedule as the underlying Basic Units to which they relate and shall be settled in accordance with the applicable provisions of the Program.

(f)                                  Adjustments to Stock Units.  The number of Stock Units credited to each Participant shall be appropriately adjusted, in order to prevent dilution or enlargement of the Participants’ rights with respect to such Stock Units, to reflect any changes in the number of outstanding shares of Company Stock resulting from any event referred to in Section 5(d) of the Plan, taking into account any Stock Units credited to the Participant in connection with such event under Section 6(e) hereof.

7.                                      Settlement

(a)                                Issuance and Delivery of Shares in Settlement.

(i)                                  Except as otherwise provided in Section 6(c) above in the case of a Participant’s Retirement, termination without Cause, death or Disability, or in the event of a Change in Control, Basic Units shall be settled by

4

issuance and delivery to the Participant (or following his or her death, to the Participant’s designated beneficiary) of a number of shares of Company Stock equal to the number of vested Basic Units credited to the Participant as of the applicable date on which such Basic Units vest, within 30 days after the date on which such Basic Units vest as set forth in Section 6(c) above.

(ii)                               Except as otherwise provided in Section 6(c) above in the case of a Participant’s Retirement, termination without Cause, death or Disability, or in the event of a Change in Control, Matching Units shall be settled by issuance and delivery to the Participant (or following his or her death, to the Participant’s designated beneficiary) of a number of shares of Company Stock equal to the number of vested Matching Units credited to the Participant as of the applicable date on which such Matching Units vest within 30 days after the date on which such Matching Units vest as set forth in Section 6(c) above.

(iii)                            The Committee may, in its discretion, make delivery of shares hereunder by depositing such shares into an account maintained for the Participant (or of which the Participant is a joint owner, with the consent of the Participant) established in connection with the Company’s Employee Stock Purchase Plan or another plan or arrangement providing for investment in Company Stock and under which the Participant’s rights are similar in nature to those under a stock brokerage account.  In the event there are fractional shares, the Company may settle any fractional share in accordance with Section 19(f) of the Plan.  In no event shall the Company in fact issue fractional shares.  Upon settlement of Stock Units, all obligations of the Company in respect of such Stock Units shall be terminated, and the shares so distributed shall no longer be subject to any restriction or other provision of the Program.

(b)                                Tax Withholding.  The Company and any Subsidiary may deduct from any payment to be made to a Participant any amount that federal, state, local, or foreign tax law requires to be withheld with respect to the settlement of Stock Units.  Unless the Committee determines otherwise, the Company will withhold from the shares of Company Stock to be distributed in settlement of Stock Units that number of shares having a Fair Market Value, at the settlement date, equal to the amount of such withholding taxes.

(c)                                 No Elective Deferral.  Participants may not elect to further defer settlement of Stock Units or otherwise to change the applicable settlement date under the Program.

8.                                      General Provisions

(a)                                No Right to Continued Employment.  Neither the Program nor any action taken hereunder, including the grant of Stock Units, will be construed as giving any Participant the right to be retained in the employ of the Company or any of its Subsidiaries, nor will it interfere in any way with the right of the Company or any of its Subsidiaries to terminate such Participant’s employment at any time.

(b)                                No Rights to Participate; No Stockholder Rights.  No Participant or employee will have any claim to participate in the Program, and the Company will have no obligation to continue the Program.  A grant of Stock Units will confer on the Participant none of the rights of a stockholder of the Company (including no rights to vote or receive dividends or distributions) until settlement by delivery of Company Stock.

(c)                                 Changes to the Program.  The Committee may amend, alter, suspend, discontinue, or terminate the Program without the consent of the Participants; provided, however, that, without the consent of an affected Participant, no such action shall materially and adversely affect the rights of such Participant with respect to outstanding Stock Units.

(d)                                Section 409A.  Except to the extent the Committee determines that Stock Units will continue to vest and be settled as provided in Section 6(c)(iii) above, it is intended that the Program and Stock Units issued hereunder be exempt from section 409A of the Code by settling such Stock Units within the short-term deferral exception set forth in the regulations under section 409A of the Code, and the Program and such Stock Units shall be interpreted on a basis consistent with such intent.  If the Committee determines that Stock Units will continue to vest under Section 6(c)(iii) above, to the extent that such determination results in such Stock Units being deemed to constitute deferred compensation subject to the requirements of section 409A of the Code, payment shall only be made under the Program upon an event and in a manner permitted by section 409A of the Code.  If any payment or

5

benefit hereunder cannot be provided or made at the time specified herein without incurring sanctions on the Participant under section 409A of the Code, then such payment or benefit shall be provided in full at the earliest time thereafter when such sanctions will not be imposed.  For purposes of section 409A of the Code, each payment made under the Program shall be treated as a separate payment, and if a payment is not made by the designated payment date under the Program, the payment shall be made by December 31 of the calendar year in which the designated date occurs.  To the extent that any provision of the Program would cause a conflict with the requirements of section 409A of the Code, or would cause the administration of the Program to fail to satisfy the requirements of section 409A, such provision shall be deemed null and void to the extent permitted by applicable law.  In no event shall a Participant, directly or indirectly, designate the calendar year of payment.  The Program may be amended in any respect deemed by the Committee to be necessary in order to preserve compliance with section 409A of the Code.

(e)                                 Recoupment Policy.  All Stock Units under this Program will be subject to any compensation clawback and recoupment policies that may be applicable to any Participant, as in effect from time to time and as approved by the Committee or Board.

9.                                      Effective Date and Termination of Program

The Program as set forth herein shall become effective as of the Effective Date.  Unless earlier terminated under Section 8(c) hereof, the Program shall terminate at such time after 2009 when no Stock Units previously granted under the Program remain outstanding.
