Explanation of Responses:

1. Owned directly by Amgen Ventures LLC ("Ventures"), a wholly-owned subsidiary of Amgen Inc. ("Amgen"). Amgen may be deemed to beneficially own securities held by Ventures, but disclaims beneficial ownership of the securities reported herein except to the extent of its pecuniary interest therein.

3. In accordance with the terms of the Warrant to Purchase Equity Securities, the warrant was net exercised and based on a fair market value of $7.00 per share, a net of 1,141 shares were acquired by Ventures.
