(a)

Amount beneficially owned:

 

As of the close of business on December 31, 2018, the Reporting Persons held 1,540,153 Warrants exercisable for an aggregate of 1,540,153 shares of Common Stock (the “Warrants”). The Warrants may not be exercised if, after such exercise, the Reporting Persons would beneficially own, as determined in accordance with Section 13(d) of the Securities Exchange Act of 1934, more than 9.99% of the number of shares of Common Stock then issued and outstanding (the “Beneficial Ownership Limitation”). Such Warrants have an initial exercise price of $2.54 per share, subject to adjustment pursuant to the terms of the Warrants. As of the close of business on December 31, 2018, the Beneficial Ownership Limitation does not limit the exercise of the Warrants by the Reporting Persons.

As of the close of business on December 31, 2018 (i) BVF beneficially owned 2,197,347 shares of Common Stock, including 742,826 shares of Common Stock issuable upon the exercise of certain Warrants, (ii) BVF2 beneficially owned 1,654,970 shares of Common Stock, including 520,707 shares of Common Stock issuable upon the exercise of certain Warrants and (iii) Trading Fund OS beneficially owned 338,020 shares of Common Stock, including 124,074 shares of Common Stock issuable upon the exercise of certain Warrants.

 

Partners OS, as the general partner of Trading Fund OS, may be deemed to beneficially own the 338,020 shares of Common Stock beneficially owned by Trading Fund OS.

 

Partners, as the general partner of BVF, BVF2, the investment manager of Trading Fund OS, and the sole member of Partners OS, may be deemed to beneficially own the 4,518,861 shares of Common Stock beneficially owned in the aggregate by BVF, BVF2, Trading Fund OS, and certain Partners managed accounts (the “Partners Managed Accounts”), including 328,524 shares of Common Stock, which includes 152,546 shares of Common Stock issuable upon the exercise of certain Warrants, held in the Partners Managed Accounts.

 

BVF Inc., as the general partner of Partners, may be deemed to beneficially own the 4,518,861 shares of Common Stock beneficially owned by Partners.

 

Mr. Lampert, as a director and officer of BVF Inc., may be deemed to beneficially own the 4,518,861 shares of Common Stock beneficially owned by BVF Inc.

 

The foregoing should not be construed in and of itself as an admission by any Reporting Person as to beneficial ownership of any shares of Common Stock owned by another Reporting Person. Partners OS disclaims beneficial ownership of the shares of Common Stock beneficially owned by Trading Fund OS. Each of Partners, BVF Inc. and Mr. Lampert disclaims beneficial ownership of the shares of Common Stock beneficially owned by BVF, BVF2, Trading Fund OS, and the Partners Managed Accounts, and the filing of this statement shall not be construed as an admission that any such person or entity is the beneficial owner of any such securities.

 

(b)

Percent of class:

 

The following percentages are based on a denominator which is the sum of: (i) 71,125,444 shares of Common Stock outstanding, as of November 6, 2018, which is the total number of shares of Common Stock outstanding as reported in the Issuer’s Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission (the “SEC”) on November 8, 2018 and (ii) certain or all of the 1,540,153 shares of Common Stock underlying certain Warrants, as applicable.

 

As of the close of business on December 31, 2018 (i) BVF beneficially owned approximately 3.1% of the outstanding shares of Common Stock, (ii) BVF2 beneficially owned approximately 2.3% of the outstanding shares of Common Stock, (iii) Trading Fund OS beneficially owned less than 1% of the outstanding shares of Common Stock, (iv) Partners OS may be deemed to beneficially own less than 1% of the outstanding shares of Common Stock, and (v) each of Partners, BVF Inc. and Mr. Lampert may be deemed to beneficially own approximately 6.2% of the outstanding shares of Common Stock (less than 1% of the outstanding shares of Common Stock are held in the Partners Managed Accounts).
