Item 4.

Ownership

 

(a)

Amount beneficially owned:

 

The Reporting Persons hold 445,231 shares of Series X convertible preferred stock, (the “Series X Preferred Stock”) convertible for an aggregate of 4,452,310 shares of Common Stock. Each share of Series X Preferred Stock is convertible into 10 shares of Common Stock. The Series X Preferred Stock may not be converted if, after such conversion, the Reporting Persons would beneficially own, as determined in accordance with Section 13(d) of the Securities Exchange Act of 1934 (the “Exchange Act”), more than 9.99% of the number of shares of Common Stock then issued and outstanding (the “Conversion Limitation”). As of the close of business on December 31, 2019, the Series X Preferred Stock Conversion Limitation limits the aggregate conversion of Series X Preferred Stock by the Reporting Persons to 681,020 out of the 4,452,310 shares of Common Stock underlying the Series X Preferred Stock owned by the Reporting Persons in the aggregate. In providing the beneficial ownership described herein, the Reporting Persons have assumed 68,102 out of 216,650 shares of Series X Preferred Stock owned by BVF would be converted.

 

In addition to the Series X Preferred Stock, the Reporting Persons hold 7,500,002 Warrants exercisable for an aggregate of 7,500,002 shares of Common Stock (the “Warrants”). The Warrants have an exercise price of $6.81 per share, subject to adjustment pursuant to the terms of 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 Exchange Act, more than 9.99% of the number of shares of Common Stock then issued and outstanding (the “Warrants Limitation”). As of the close of business on December 31, 2019, the Warrants Limitation limits the aggregate exercise of Warrants by the Reporting Persons to zero out of the 7,500,002 shares of Common Stock underlying the Warrants owned by the Reporting Persons in the aggregate.

 

As of the close of business on December 31, 2019, (i) BVF beneficially owned 1,793,630 shares of Common Stock, including 681,020 shares of Common Stock issuable upon the conversion of Series X Preferred Stock and excluding (a) 1,485,480 shares of Common Stock issuable upon the conversion of Series X Preferred Stock and (b) 3,649,460 shares of Common Stock issuable upon the exercise of Warrants, (ii) BVF2 beneficially owned approximately 1,339,735 shares of Common Stock, excluding (a) 1,475,120 shares of Common Stock issuable upon the conversion of Series X Preferred Stock and (b) 2,484,899 shares of Common Stock issuable upon the exercise of Warrants, and (iii) Trading Fund OS beneficially owned 104,229 shares of Common Stock, excluding (a) 357,470 shares of Common Stock issuable upon the conversion of Series X Preferred Stock and (b) 602,173 shares of Common Stock issuable upon the exercise of Warrants.

 

BVF GP, as the general partner of BVF, may be deemed to beneficially own the 1,793,630 shares of Common Stock beneficially owned by BVF.

 

BVF2 GP, as the general partner of BVF2, may be deemed to beneficially own the 1,339,735 shares of Common Stock beneficially owned by BVF2.

 

Partners OS, as the general partner of Trading Fund OS, may be deemed to beneficially own the 104,229 shares of Common Stock beneficially owned by Trading Fund OS.

 

BVF GPH, as the sole member of each of BVF GP and BVF2 GP, may be deemed to beneficially own the 3,133,365 shares of Common Stock beneficially owned in the aggregate by BVF and BVF2.

 

Partners, as the investment manager of BVF, BVF2 and Trading Fund OS, and the sole member of Partners OS, may be deemed to beneficially own the 3,368,758 shares of Common Stock beneficially owned in the aggregate by BVF, BVF2 and Trading Fund OS, including 131,164 shares of Common Stock held in certain of the Partners managed accounts (the “Partners Managed Accounts”) and excluding (a) 453,220 shares of Common Stock issuable upon the conversion of Series X Preferred Stock held in the Partners Managed Accounts and (b) 763,470 shares of Common Stock issuable upon the exercise of Warrants held in the Partners Managed Accounts.

 

BVF Inc., as the general partner of Partners, may be deemed to beneficially own the 3,368,758 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 3,368,758 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. BVF GP disclaims beneficial ownership of the shares of Common Stock beneficially owned by BVF. BVF2 GP disclaims beneficial ownership of the shares of Common Stock beneficially owned by BVF2. Partners OS disclaims beneficial ownership of the shares of Common Stock beneficially owned by Trading Fund OS. BVF GPH disclaims beneficial ownership of the shares of Common Stock beneficially owned by BVF and BVF2. 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.
