Explanation of Responses:
(1)	This Form 4 reports securities disposed of pursuant to the terms of the Agreement and Plan of Merger (the "Merger Agreement"), dated as of November 17, 2021, by and among the Issuer, Novo Nordisk A/S, a Danish aktieselskab ("Novo"), and NNUS New Research, Inc., a Delaware corporation and a wholly owned indirect subsidiary of Novo ("Purchaser"), to which Purchaser completed a tender offer for shares of common stock of Issuer, $0.0001 par value per share (each, a "Share") and thereafter merged with and into the Issuer (the "Merger") effective as of December 28, 2021 (the "Effective Time"). At the Effective Time, each issued and outstanding Share was converted into the right to receive $38.25 per Share, in cash, without interest (the "Offer Price") and subject to any withholding of taxes, upon the terms and subject to the conditions of the Merger Agreement. From and after the Effective Time, all Shares were no longer outstanding and were automatically cancelled.
(2)	Each restricted stock unit ("RSU") represents the contingent right to receive one Share.
(3)	At the Effective Time, each Issuer RSU that was then outstanding was cancelled and converted into the right to receive a cash payment equal to (A) the Offer Price multiplied by (B) the total number of Shares subject to such Issuer RSU immediately prior to the Effective Time (without regard to vesting).
(4)	Pursuant to the terms of the Merger Agreement, at the Effective Time, each option to purchase Shares granted under an Issuer equity plan (each, an "Issuer Stock Option") that was outstanding and unexercised was cancelled and converted into the right to receive a cash payment equal to (A) the excess, if any, of (x) the Offer Price over (y) the exercise price payable per Share with respect to such Issuer Stock Option, multiplied by (B) the total number of Shares subject to such Issuer Stock Option immediately prior to the Effective Time (without regard to vesting).
