Explanation of Responses:
( 1)	The convertible preferred stock has no expiration date. As a result of a one-for-3.03 reverse split of MAKO Surgical Corp. (the "Company") common stock, each share of convertible preferred stock is convertible into .330033 of a share of common stock. Accordingly, upon the closing of the issuer's initial public offering, the convertible preferred stock will convert into the number of shares of common stock set forth in Column 3.
( 2)	Tudor Investment Corporation ("TIC") is the investment adviser or trading advisor to each of The Tudor BVI Global Portfolio L.P. (f/k/a The Tudor BVI Global Portfolio Ltd.) ("BVI") and The Raptor Global Portfolio Ltd. ("Raptor"), and the General Partner of The Altar Rock Fund L.P. ("Altar Rock"). The shares of Common Stock (collectively, "Common Stock") as reported herein as indirectly beneficially owned by TIC are directly beneficially owned by BVI (368,855 shares), Raptor (1,107,917 shares), and Altar Rock (9,862 shares). Because TIC is the sole General Partner of Altar Rock and provides investment-advisory services to BVI and Raptor, TIC may be deemed to beneficially own the shares of Common Stock owned by each of such entities. TIC disclaims beneficial ownership of the securities reported herein as indirectly owned except to the extent of its pecuniary interest in such securities.
( 3)	The shares of Common Stock (the "Shares") are reported herein as indirectly beneficially owned by Paul Tudor Jones II. The Shares are owned indirectly by TIC (1,486,634 shares) (see Footnote 2). Because Mr. Jones is the controlling shareholder of TIC, Mr. Jones may be deemed to beneficially own the Shares deemed beneficially owned by TIC. Mr. Jones expressly disclaims such beneficial ownership.
( 4)	The Shares are reported herein as indirectly beneficially owned by James J. Pallotta. The Shares are owned indirectly by TIC (1,486,634 shares) (see Footnote 2). Because Mr. Pallotta is the portfolio manager of TIC with respect to the Shares and may be deemed to have voting and investment authority with respect to the Shares, Mr. Pallotta may be deemed to beneficially own the Shares deemed beneficially owned by TIC. Mr. Pallotta expressly disclaims such beneficial ownership.
( 5)	Michael P. Stansky, a Managing Director of TIC, is a Director of the Company. Mr. Stansky disclaims beneficial ownership of any shares that may be deemed to be beneficially owned by TIC.
