Explanation of Responses:

1. Each share of our Series F Preferred Stock and Series E-2 Preferred Stock will convert into Common Stock immediately prior to the completion of the Issuer's initial public offering pursuant to its terms.

2. The securities are held by Osage University Partners III, LP ("OUP III"). Osage University GP III, LLC ("OUP III GP") is the general partner of OUP III. William Harrington ("Mr. Harrington") is a manager of OUP III GP and may be deemed to share voting and dispositive power over the shares held by OUP III.

3. The Convertible Notes will automatically convert into Common Stock immediately prior to the closing of the Issuer's initial public offering (the "Offering"). The conversion price is the lower of (a) 80% of the Offering price per share and (b) the valuation of the Issuer immediately prior to the closing of the Offering divided by the number of fully diluted shares of capital stock (on an as-converted basis) outstanding immediately prior to Offering, excluding the Convertible Notes.
