Explanation of responses
- F1Each share of Series A Preferred Stock, Series A-1 Preferred Stock, and Series B Preferred Stock automatically converted into 0.72 of a share of common stock immediately prior to the closing of the Issuer's initial public offering, and has no expiration date.
- F2Pursuant to the terms of the Series B Preferred Stock Warrant (the "Old Warrant"), effective upon conversion of all outstanding shares of Series B Preferred Stock of the Issuer, the Old Warrant converts into a Warrant to purchase shares of Common Stock of the Issuer (the "New Warrant"). The two transactions reported in Table II above show the cancellation of the Old Warrant and acquisition of the New Warrant in connection with the automatic conversion of the Series B Preferred Stock into 0.72 of a share of common stock immediately prior to the closing of the Issuer's initial public offering.
