This SHAREHOLDER AGREEMENT dated as of [ ], 2012 (this “Agreement”), by and between BATS Global Markets, Inc., a Delaware corporation (the “Company”) and [strategic investor], a holder of Class B Stock (as defined below) (such holder being herein called the “Shareholder”).

W I T N E S S E T H:

WHEREAS, the Shareholder holds shares of the Company’s Class B common stock, par value $0.01 per share (the “Class B Stock”); and

WHEREAS, the parties hereto desire to enter into this Agreement to govern certain of their rights, duties and obligations after consummation of the initial public offering of shares of Class A common stock of the Company (the “IPO”).

NOW, THEREFORE, in consideration of the covenants and agreements contained herein and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, intending to be legally bound hereby, the parties hereto agree as follows:

1. Composition of the Board. Following the consummation of the IPO, for so long as the Shareholder owns any shares of Class B Stock, the Shareholder shall have the right to appoint a representative (a “Board Observer”) to attend, as a non-voting observer, each meeting of the board of directors of the Company (the “Board”) other than any portion of a meeting that is designated as an executive session, whether such meeting is conducted in person or by teleconference or videoconference. The appointment of a Board Observer pursuant to this Section 1 shall be effective upon written notice from the Shareholder to the Company of the name and contact information of the individual so appointed.

2. Vacancy. If the individual appointed pursuant to Section 1 to act as a Board Observer is no longer able or willing to act as Board Observer, the Shareholder may appoint another individual to act as a Board Observer pursuant to the provisions of Section 1.

3. Board Observer. A Board Observer appointed pursuant to Section 1 shall have the right to present matters for consideration by the Board and to speak on matters presented by others at such meetings of the Board. A Board Observer shall not be entitled to attend meetings of any Board committee except for meetings of special or standing committees to which the Board Observer has been

granted in writing by the Board the right to attend one or more such meetings. A Board Observer shall not have the right to vote on any matter presented to the Board or any committee thereof. Subject to the confidentiality provisions of this Section 3 and any applicable related person, conflict of interest, recusal or similar policy or practice of the Company, the Company shall cause the Board Observer to be provided with all communications and materials that are provided by the Company or its consultants to the members of the Board generally, at the same time and in the same manner that such communications and materials are provided to such members, including all notices, board packages, reports, presentations, minutes and consents. The Board Observer shall be entitled to meet and consult with the senior executive management team of the Company on a quarterly basis to discuss the quarterly and annual business plans of the Company and the Company’s subsidiaries and to review the progress of the Company and the Company’s subsidiaries in achieving their plans. In addition, upon request to the chief executive officer of the Company, the members of the senior executive management team of the Company shall make themselves available during normal business hours to meet with the Board Observer on an interim basis, as the Board Observer may reasonably request from time to time, and as would not unreasonably interfere with the duties of the members of the senior executive management team of the Company.

Notwithstanding any other provision of this Section 3 to the contrary, the Company or the Board shall have the right to keep confidential from the Board Observer for such period of time as the Company or the Board deems reasonable any information and copies of written materials the Company is required by law, rule, regulation or agreement with a third party to keep confidential. The Board Observer shall hold in confidence and trust and not use or disclose any confidential information provided to or learned by him or her in connection with the Board Observer’s rights hereunder for any purpose other than the observation and participation rights contemplated hereby, unless otherwise required by law. As a condition of the exercise of his or her rights under this Section 3, the Board Observer shall enter into such further agreements or undertakings with the Company to maintain the confidentiality of information provided to them in connection with the exercise of such rights as the Company may reasonably request.

The Shareholder will cause each Board Observer appointed by it to agree to abide by and be subject to the obligations imposed upon members of the Board pursuant to Article 12 of the Company’s bylaws (or any successor provision thereto) and Section 3 of the Company’s Code of Business Conduct and Ethics (or any successor provision thereto).

6. Assignment. Neither this Agreement nor any of the rights or obligations hereunder shall be assigned by any party hereto without the prior written consent of the other party. This Agreement will be binding upon, inure to the benefit of and be enforceable by the parties and their respective successors and permitted assigns.

7. Waiver; Amendment. No provision of this Agreement may be waived unless such waiver is in writing and signed by the party against whom the waiver is to be effective. No provision of this Agreement may be amended unless such amendment is approved in writing by the Company and the Shareholder.

8. Counterparts. This Agreement may be executed (including by facsimile transmission) with counterpart pages or in one or more counterparts, each of which shall be deemed to be an original and all of which shall, taken together, be deemed to be one and the same instrument.

9. Governing Law. This Agreement shall be governed by, construed and enforced in accordance with, the laws of the State of Delaware, without regard to the conflicts of laws rules of such state.

10. Consent to Jurisdiction. The parties hereto agree that any suit, action or proceeding seeking to enforce any provision of, or based on any matter arising out of or in connection with, this Agreement or the transactions contemplated hereby shall be brought in the United States District Court for Delaware or any Delaware court sitting in the Borough of Manhattan, so long as one of such courts shall have subject matter jurisdiction over such suit, action or proceeding, and that any cause of action arising out of this Agreement shall be deemed to have arisen from a transaction of business in the State of Delaware, and each of the parties hereby irrevocably consents to the jurisdiction of such courts (and of the appropriate appellate courts therefrom) in any such suit, action or proceeding and irrevocably waives, to the fullest extent permitted by law, any objection that it may now or hereafter have to the laying of the venue of any such suit, action or proceeding in any such court or that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum.

Process in any such suit, action or proceeding may be served on any party anywhere in the world, whether within or without the jurisdiction of any such court.

11. Waiver of Jury Trial. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.
