| Item 4. | Ownership |
| (a) | Amount beneficially owned: |
As of the close of business on January 29, 2018, the Reporting Persons hold 5,000,000 warrants, exercisable for an aggregate of 2,500,000 shares of Common Stock (the “Warrants”). Each Warrant entitles the holder thereof to acquire, for a nominal exercise price, one-half share of Common Stock. The Warrants are only exercisable to the extent that the holder, together with its affiliates and any other person or entity acting as a group, would not beneficially own more than 9.99% of the outstanding shares of Common Stock after giving effect to such exercise, as such percentage ownership is determined in accordance with the terms of the Warrants (the “Beneficial Ownership Limitation”). As of January 29, 2018, the Beneficial Ownership Limitation does not limit the exercise of the Warrants by the Reporting Persons.
As of the close of business on January 29, 2018 (i) BVF beneficially owned 3,543,560 shares of Common Stock (which includes 1,181,187 shares of Common Stock underlying certain Warrants), (ii) BVF2 beneficially owned 2,367,361 shares of Common Stock (which includes 789,120 shares of Common Stock underlying certain Warrants), and (iii) Trading Fund OS beneficially owned 607,632 shares of Common Stock (which includes 202,544 shares of Common Stock underlying certain Warrants).
Partners OS, as the general partner of Trading Fund OS, may be deemed to beneficially own the 607,632 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 7,500,000 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 981,447 shares of Common Stock held in the Partners Managed Accounts (which includes 327,149 shares of Common Stock underlying certain Warrants).
BVF Inc., as the general partner of Partners, may be deemed to beneficially own the 7,500,000 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 7,500,000 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) 82,069,164 shares of Common Stock outstanding, as disclosed in the Issuer’s Prospectus filed with the Securities and Exchange Commission on January 18, 2018 and (ii) certain of the 2,500,000 shares of Common Stock underlying certain Warrants, as applicable.
As of the close of business on January 29, 2018 (i) BVF beneficially owned approximately 4.2% of the outstanding shares of Common Stock, (ii) BVF2 beneficially owned approximately 2.8% 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 8.9% of the outstanding shares of Common Stock (approximately 1.2% is held in the Partners Managed Accounts).
