PURSUANT TO THE
MARKETAXESS HOLDINGS INC. 2004 STOCK INCENTIVE PLAN
(AMENDED AND RESTATED EFFECTIVE APRIL 28, 2006)

THIS RESTRICTED STOCK UNIT AGREEMENT (this “Agreement”), is dated January 19, 2011 (the “Grant Date”) by and between MarketAxess Holdings Inc. (the “Company”) and you (the “Participant”).

WHEREAS, the Board of Directors of the Company (the “Board”) adopted The MarketAxess Holdings Inc. 2004 Stock Incentive Plan (Amended and Restated Effective April 28, 2006) (the “Plan”) which is administered by a Committee appointed by the Company’s Board of Directors (the “Committee”);

WHEREAS, pursuant to Section 3.3 of the Plan, the Committee has adopted guidelines (the “Guidelines”) for the grant of restricted stock units (“RSUs”) under the Plan, which constitute an Other Stock-Based Award under the Plan; and

WHEREAS, the Company, through the Committee, wishes to grant to the Participant RSUs as set forth below.

NOW, THEREFORE, the Company and the Participant agree as follows:

1.		Grant of RSUs. Subject to the terms and conditions of the Plan, the Guidelines and this Agreement, on the Grant Date the Company awarded to the Participant 119,565 RSUs. The RSUs are Deferrable RSUs and the payment of shares of Common Stock upon vesting in accordance with Section 2 may be deferred by the Participant in accordance with Section 4 of the Guidelines. If the Participant chooses to defer the RSUs, the Participant must complete an election form prescribed by the Committee regarding the election period no later than 30 days after the Grant Date. If the Participant has Deferrable RSUs, but does not make an election within 30 days after the Grant Date, the RSUs will not be treated as Deferrable RSUs.
2.		Vesting.

2.1 Except as set forth in this Section 2, and notwithstanding anything in the Guidelines to the contrary (including without limitation Section 3.1 of the Guidelines), the RSUs shall become vested (but shall remain subject to Section 3 of this Agreement) pursuant to the following schedule, provided that the Participant has not had a Termination from the date of grant until the applicable vesting date:

		Incremental Percentage of RSUs
Vesting Date		Vested
February 19, 2012			12.5	%
January 15, 2013			25.0	%
January 15, 2014			25.0	%
January 15, 2015			25.0	%
January 15, 2016			12.5	%

2.2 Notwithstanding Section 2.1 of this Agreement and anything in the Guidelines to the contrary (including without limitation Sections 3.3 and 3.4(iv) of the Guidelines):

(a) upon the Participant’s death or Disability 50% of any RSUs that are unvested on the date of the Participant’s death or Disability, as applicable, shall become immediately vested; and

(b) upon the Participant’s Termination (x) by the Company without Cause, or (y) by the Participant for Good Reason, that in any case occurs on or after February 19, 2012, any portion of the RSUs that would have otherwise become vested in (x) the twelve (12) month period following the date of such Termination if such Termination occurs outside of a Change in Control Period or (y) the twenty-four (24) month period following the date of such Termination if such Termination occurs during a Change in Control Period, shall become immediately vested on the date of such Termination.

“Change in Control Period” means the three (3) month period prior to, and the eighteen month period following, a Change in Control that constitutes a Change in Control Event within the meaning of Section 409A of the Code.

2.3 Notwithstanding anything herein to the contrary, in the event of the Participant’s Termination as a result of the Company’s non-extension of the letter agreement between the Company and the Participant, dated January 19, 2011, in accordance with the terms thereof, the then unvested portion of the RSUs shall continue to become vested in accordance with Section 2.1, as if a Termination shall not have occurred.

2.4 There shall be no proportionate or partial vesting in the periods prior to each vesting date and all vesting shall occur only on the appropriate vesting date.

3. Securities Representations. The grant of the RSUs and any issuance of shares of Common Stock pursuant to this Agreement are being made by the Company in reliance upon the following express representations and warranties of the Participant.

The Participant acknowledges, represents and warrants that:

3.1 he or she has been advised that he or she may be an “affiliate” within the meaning of Rule 144 under the Securities Act of 1933, as amended (the “Act”) and in this connection the Company is relying in part on his or her representations set forth in this section;

3.2 if he or she is deemed an affiliate within the meaning of Rule 144 of the Act, the Common Stock must be held indefinitely unless an exemption from any applicable resale restrictions is available or the Company files an additional registration statement (or a “re-offer prospectus”) with regard to such Common Stock and the Company is under no obligation to register the Common Stock (or to file a “re-offer prospectus”); and

3.3 if he or she is deemed an affiliate within the meaning of Rule 144 of the Act, he or she understands that the exemption from registration under Rule 144 will not be available unless (i) a public trading market then exists for the Common Stock, (ii) adequate information concerning the Company is then available to the public, and (iii) other terms and conditions of Rule 144 or any exemption therefrom are complied with; and that any sale of the Common Stock may be made only in limited amounts in accordance with such terms and conditions.
