(1)	The purchases of shares of unrestricted common stock and the call option with respect to shares of unrestricted common stock reported herein resulted in a short swing profit under Section 16(b) of the Securities Exchange Act of 1934, as amended, with respect to 300 shares of unrestricted common stock sold on May 17, 2011 pursuant to a Rule 10b5-1 trading plan. Upon settlement of the sale, the reporting person will disgorge to CBOE Holdings the full amount of the profit realized in connection with such short-swing transactions.
(2)	All purchase transactions reported on this Form 4 were inadvertent and reflect internal controls testing by Group One Trading to ensure that its traders could not affect transactions in CBOE Holdings stock. Once it was determined that the transactions had occurred, the securities acquired were immediately sold. Mr. Londergan was not involved in either the decision to test the internal controls nor the purchases and sales.
(3)	The prices reported in Column 4 are each a weighted average price. The shares were purchased in blocks of 100 shares at $26.96 and $26.98, respectively. The shares were sold in 100 share blocks at $26.93 and $26.99, respectively.
(4)	Reflects shares owned by Group One Trading, L.P. Mr. Londergan is chief executive officer of Group One Trading, L.P. Mr. Londergan disclaims beneficial ownership of those shares in which he does not have a pecuniary interest.
