(1) The convertible preferred stock is immediately convertible on a 1:2.86 basis and has no expiration date. The convertible preferred stock automatically converts to Common Stock upon the closing of the offering.
(2) Shares include (a) 5,391,648 shares issuable upon conversion of preferred stock and (b) 356,644 shares issuable upon conversion of convertible notes owned by Brookside Capital Partners Fund, L.P. ("Brookside Fund"), whose sole general partner is Brookside Capital Investors, L.P. ("Brookside Investors"), whose sole general partner is Brookside Capital Management, LLC ("Brookside Management"). Domenic Ferrante is the managing member of Brookside Management and a limited partner of Brookside Investors. Mr. Ferrante, Brookside Investors and Brookside Management may each be deemed to share voting and dispositive power with respect to the shares owned by Brookside Fund, but each disclaims beneficial ownership of such shares except to the extent of their pecuniary interests therein.
(3) Following consummation of the Issuer's initial public offering, the reporting persons herein will cease to hold, directly or indirectly, more than 10% of any class of any equity security of the issuer (determined in accordance with the rules for determining beneficial ownership under Section 13(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act")) and therefore will no longer be subject to the disclosure and other requirements of Section 16 of the Exchange Act.
