Pursuant to the Merger, securities of Old Discovery held by Aries Domestic and Aries Fund were converted into securities of the Issuer. The Reporting Person is the general partner of Aries Domestic and also serves as the investment manager to Aries Fund and in such capacities has the authority to make certain decisions on behalf of such entities including decisions relating the securities of the Issuer. The securities of Old Discovery surrendered by Aries Domestic and Aries Fund in the Merger constituted the consideration for the securities of the Issuer issued to Aries Domestic and Aries Fund in the Merger. The securities of Old Discovery were not listed on a securities exchange or quoted on an inter-dealer quotation system and, accordingly, the Issuer is unable to determine the value of such consideration as of the date of the Merger. The Reporting Person disclaims beneficial ownership of the securities held by Aries Domestic and Aries Trust, except to the extent of its pecuniary interest therein, if any. (2) Includes 385,265 shares of Common Stock issuable upon conversion of Series B Convertible Preferred Stock (including Series B Convertible Preferred Stock issuable upon exercise of Series B Convertible Preferred Stock Warrants) and 8,756 shares of Common Stock issuable upon exercise of Common Stock Warrants. (3) The Reporting Person is the general partner in Aries Domestic and the investment manager to Aries Fund. Aries Domestic and Aries Fund beneficially own, directly, all of the securities reported on this Form 5 as being beneficially owned by the Reporting Person. (4) Includes 6,750 shares of Series B Convertible Preferred Stock issuable upon exercise of Series B Convertible Preferred Stock Warrants held by Aries Domestic and 15,750 shares of Series B Convertible Preferred Stock issuable upon exercise of Series B Convertible Preferred Stock Warrants held by Aries Fund. (5) The Common Stock Warrants and Series B Convertible Preferred Stock Warrants were issued to Aries Domestic and Aries Fund in connection with a private placement of equity securities of Old Discovery in which an affiliate of Aries Domestic and Aries Fund (and of the Reporting Person) acted as placement agent. The Common Stock Warrants and Series B Convertible Preferred Stock Warrants were assumed by the Issuer in the Merger. /s/ Lindsay A.
