Supplement to the Notice of Annual Meeting and Proxy Statement for
the 2013 Annual Meeting of Stockholders of CBOE Holdings, Inc.
To be held on Thursday, May 23, 2013, at 9:30 a.m., local time,
in the fourth floor lounge of the Chicago Board Options Exchange, Incorporated,
at 400 South LaSalle Street, Chicago, Illinois, 60605

Dear Stockholder:
This supplement provides updated and amended information with respect to the 2013 Annual Meeting of Stockholders (the “Annual Meeting”) of CBOE Holdings, Inc. (the “Company”). Except as amended or supplemented by the information contained in this supplement, all information set forth in the Notice of Annual Meeting and Proxy Statement dated April 4, 2013 (the “Proxy Statement”) remains accurate and should be considered in casting your vote by proxy or in person at the annual meeting.
The purpose of this supplement is to revise the list of nominees for election to our Board of Directors as set forth in the Proxy Statement. On May 20, 2013, Douglas H. Shulman withdrew his candidacy for election to the Company's Board of Directors at the Annual Meeting. We understand that Mr. Shulman's decision to withdraw his candidacy for election was due to the timing of his testimony before Congress and was not due to any disagreement or dispute between the Company and Mr. Shulman. Our Board of Directors has not nominated a replacement for Mr. Shulman for election at the Annual Meeting to fill the expected vacancy following the Annual Meeting. Our Board of Directors may reduce the number of directors to eliminate the vacancy, allow the vacancy to remain unfilled for some period of time or appoint a director to fill the vacancy in the future, in each case based on whether our Board of Directors believes they have identified a candidate with the necessary skills, qualifications and experiences to serve on the Board of Directors.
If the expected vacancy is filled by vote of a majority of the directors, the director elected to fill the vacancy will hold office until the next annual meeting of stockholders, subject to the election and qualification of his successor and to his earlier death, resignation or removal.
If you have already submitted your proxy, you do not need to take any action unless you wish to change your vote.  This supplement does not change the proposals to be acted upon at the Annual Meeting, which are described in the Proxy Statement, except that Mr. Shulman will no longer be standing for election as a director. No votes received prior to or after the date of this supplement will be counted for the election of Mr. Shulman to our Board of Directors.
The Proxy Statement is available on the Investor Relations section of our website at http://ir.CBOE.com/annual-proxy.cfm.
Sincerely,
William J. Brodsky
Chairman and Chief Executive Officer

May 20, 2013

All stockholders are cordially invited to attend the meeting in person. However, to assure your representation at the Annual Meeting, and in case you have not already done so, you are urged to vote online, by telephone or by completing and mailing the proxy card that was enclosed with your Proxy Statement as promptly as possible. For specific instructions for voting online, by telephone or by mail, please see the proxy card. Any stockholder attending the Annual Meeting may vote in person even if the stockholder has previously returned a proxy.





SUPPLEMENTAL INFORMATION
Withdrawal of Douglas Shulman
On May 20, 2013, Douglas H. Shulman withdrew his candidacy for election to the Company's Board of Directors at the Annual Meeting. Mr. Shulman was standing for election at the Annual Meeting as a director to serve until the 2014 annual meeting of stockholders.
As a result of Mr. Shulman's withdrawal, only 14 directors will stand for election at the Annual Meeting. As more fully described in the Proxy Statement, our Board of Directors has nominated each of William J. Brodsky, James R. Boris, Frank E. English, Jr., Edward J. Fitzpatrick, Janet P. Froetscher, Jill R. Goodman, Duane R. Kullberg, R. Eden Martin, Roderick A. Palmore, Susan M. Phillips, Samuel K. Skinner, Carole E. Stone, Eugene S. Sunshine and Edward T. Tilly as directors. Our Board of Directors unanimously recommends that you vote your shares “for” these nominees to our Board of Directors.
VOTING; REVOCABILITY OF PROXIES
If you have already submitted your proxy, you do not need to take any action unless you wish to change your vote. Proxies that have already been received by stockholders will remain valid and will be voted at the annual meeting unless revoked. Shares represented by proxies received before the Annual Meeting will be voted for the director nominated by the Board of Directors as instructed by the proxies, except that votes will not be cast for Mr. Shulman as he is no longer a nominee for election to the Board of Directors. No other person has been nominated by the Board of Directors to replace Mr. Shulman.
If you are a stockholder of record, you may revoke your proxy or change your vote at any time before it is voted at the Annual Meeting by:
submitting a new proxy by telephone or through the Internet, after the date of the earlier voted proxy;
returning a signed proxy card dated later than your last proxy;
submitting a written revocation to the Corporate Secretary of CBOE Holdings, Inc. at 400 South LaSalle Street, Chicago, Illinois 60605; or
appearing in person and voting at the Annual Meeting.
If you are a stockholder of record and need a new proxy card, to change your vote or otherwise, please contact the Corporate Secretary at the address above.
If your bank, broker or other nominee holds your shares in “street name,” you may revoke your proxy or change your vote only by following the separate instructions provided by your bank, broker or nominee.
To vote in person at the Annual Meeting, you must attend the meeting and cast your vote in accordance with the voting provisions established for the Annual Meeting. Attendance at the Annual Meeting without voting in accordance with the voting procedures does not, by itself, revoke a proxy. If your bank, broker or other nominee holds your shares and you want to attend and vote your shares at the Annual Meeting, you must bring a legal proxy signed by your bank, broker or nominee to the Annual Meeting.
