ARTICLE II
CORPORATE GOVERNANCE

Section 2.1                                    SL Director.

(a)                                 The parties hereby agree that SL shall have the right, so long as the Aggregate SL Ownership exceeds the SL Ownership Minimum, to designate one individual (the “SL Director”) for nomination to the Board, subject to the proper exercise of the fiduciary duties of the Board (or the appropriate committee thereof) with respect to director nominations.

(b)                                 For so long as the Company Charter shall provide for the division of directors into three classes, the SL Director shall be designated as a Class III director. The initial SL Director is Michael Bingle.  Joseph Osnoss shall initially be designated as a Class I director.

(c)                                  In connection with the election of Class III directors, the Company shall nominate the SL Director for election as a director as part of the slate that is included in the proxy statement (or consent solicitation or similar document) of the Company relating to the election of such directors, shall recommend the election of such nominee, and shall provide the highest level of support to cause the election of such nominee as it provides to any other individual standing for election as a director of the Company as part of the Company’s slate of Class III directors.  In the event the Company Charter shall not provide for the division of directors into three classes, the Company shall nominate the SL Director for election as a director as part of the slate that is included in the proxy statement (or consent solicitation or similar document) of the Company relating to the election of directors, shall recommend the election of such nominee, and shall provide the highest level of support to cause the election of such nominee as it provides to any other individual standing for election as a director of the Company as part of the Company’s slate of directors.

(d)                                 With respect to any SL Director to be nominated by SL other than the initial SL Director identified in Section 2.1(b), SL shall nominate such SL Director by delivering to the Company a written statement at least 90 days prior to the one-year anniversary of the preceding annual meeting nominating directors, or such shorter period as is agreed in writing by the Company, and setting forth such individual’s business address, telephone number, facsimile number and e-mail address; provided, that if SL shall fail to deliver such written notice, SL shall be deemed to have nominated the SL Director previously nominated (or designated pursuant to this Section 2.1(d)) by SL who is currently serving on the Board; provided, further, that in the event that the SL Director becomes permanently disabled or dies or otherwise resigns within 90 days prior to the one-year anniversary of the preceding annual meeting, SL shall be permitted to nominate a replacement SL Director and the Company shall use its reasonable best efforts to comply with its obligations herein, including filing and disseminating an amendment to the proxy statement (or consent solicitation or similar document) of the Company relating to the election of directors.

(e)                                  SL shall have the exclusive right to remove the SL Director from the Board, subject to the rights of holders of Company Securities (other than the Viola Stockholders) under applicable law, and the Company and the Viola Stockholders shall take all Necessary Action reasonably available within their power to cause the removal of any such designee at the request of SL.  SL shall have the exclusive right to

designate for election to the Board a director to fill any vacancy created by reason of the permanent disability, death, removal or resignation of the SL Director, and the Company and the Viola Stockholders shall take all Necessary Action reasonably available within their power to cause any such vacancy to be filled by a replacement SL Director designated by SL as promptly as practicable.  In addition, with respect to any SL Director to be nominated by SL other than a Managing Director (or more senior officer) of an SL Party or any of its affiliated management companies, SL shall select such SL Director in consultation with the Nominating Committee of the Board.  SL shall use commercially reasonable efforts to cause the SL Director at all times to comply with the Company’s corporate policies, including, without limitation, its code of ethics, and SL shall promptly remove any SL Director who fails to comply with such corporate policies (provided, that (i) the Company has provided the SL Director a written copy of such corporate policies reasonably in advance of the date on which the SL Director is obligated to comply therewith, (ii) such corporate policies apply to all members of the Board in an equal manner and do not apply differently or disproportionately to the SL Director as compared to other members of the Board and (iii) such corporate policies are enforced by the Company and its Subsidiaries against all members of the Board equally and to the same extent; provided, further, that such corporate policies shall not conflict with or otherwise be inconsistent with any agreement entered into by any SL Party (x) with the Company, Virtu Financial or any of Virtu Financial’s Subsidiaries in connection with the IPO, including this Agreement, or (y) with the Underwriters to the IPO in connection with the IPO or otherwise create any liability or obligation of the SL Director that is not reasonable or customary for public companies whose boards of directors include professionals from private equity firms or financial sponsors) after reasonable notice from the Company is provided to SL and the SL Director and the SL Director is given a reasonable opportunity to comply with such corporate policies.

(f)                                   If at any time the Aggregate SL Ownership is equal to or less than the SL Ownership Minimum, SL shall, if requested by the Company in writing, cause the SL Director to immediately resign from the Board, and SL shall no longer have the right to designate any director to the Board.

(g)                                  For the avoidance of doubt, any member of the Board other than the SL Director, including Joseph Osnoss, may be removed from the Board in accordance with the provisions of the Company Charter and the Company By-Laws.

(h)                                 The Company shall reimburse the SL Director and any other director affiliated with any of the SL Parties for all reasonable out-of-pocket costs and expenses (including travel expenses) incurred in connection with such director’s attendance and participation at meetings of the Board or any committee thereof.
