Item 4.

Ownership.

 

Items 5 through 9 and 11 of each of the cover pages to this Amendment No. 3 are incorporated herein reference. Set forth below is the aggregate number of shares of Common Stock of the Issuer directly held by each of the 667, L.P. and Baker Brothers Life Sciences, L.P. (collectively the "Funds"), which may be deemed to be indirectly beneficially owned by the Reporting Persons. The information set forth below is based upon 154,059,115 shares of Common Stock outstanding as of November 19, 2019, as reported on the Issuer's Prospectus filed with the SEC on November 21, 2019, plus 30,000 shares of Common Stock underlying options to purchase Common Stock ("Stock Options") and 4,821,046 shares of Common Stock issuable upon the exercise of the Pre-Funded Warrants (as defined below). Such percentage figures were calculated in accordance with Rule 13d-3 under the Securities Exchange Act of 1934, as amended (the "Exchange Act").

 

 

		Number of Shares of
		Common Stock we
		own or have the right
		to acquire within 60				Percent of Class
Holder		days				Outstanding
667, L.P.			1,898,216				1.2	%
Baker Brothers Life Sciences, L.P.			14,810,620				9.3	%

 

The warrants have an exercise price of $0.01 per share with no expiration date (the “Pre-Funded Warrants. The Pre-Funded Warrants are only exercisable to the extent that after giving effect to such exercise the holders thereof and their affiliates would beneficially own, for purposes of Rule 13d-3 under the Exchange Act, no more than 9.99% of the outstanding shares of Common Stock (“Maximum Percentage”). By written notice to the Issuer, the Funds may from time to time increase or decrease the Maximum Percentage applicable to that Fund to any other percentage not in excess of 19.99%. Any such change will not be effective until the 61st day after such notice is delivered to the Issuer. As a result of this restriction, the number of shares that may be issued upon exercise of the Pre-Funded Warrants by the above holders may change depending upon changes in the outstanding shares of Common Stock.

 

As a result of this restriction, the number of shares that may be issued upon exercise of the Pre-Funded Warrants by the above holders may change depending upon changes in the outstanding shares of Common Stock.

 

The Adviser GP, Felix J. Baker and Julian C. Baker, as managing members of the Adviser GP, and the Adviser may be deemed to be beneficial owners of securities of the Issuer directly held by the Funds.

 

Pursuant to the management agreements, as amended, among the Adviser, the Funds and their respective general partners, the Funds’ respective general partners relinquished to the Adviser all discretion and authority with respect to the investment and voting power of the securities held by the Funds, and thus the Adviser has complete and unlimited discretion and authority with respect to the Funds’ investments and voting power over investments. Julian C. Baker and Felix J. Baker each directly hold and beneficially own 77,913 shares of Common Stock of the Issuer received from pro-rata distributions without consideration.

 

Dr. Stephen R. Biggar, an employee of the Adviser, is a former Director of the Issuer. In connection with his previous service on the Board of Directors of the Issuer (the “Board”), Dr. Biggar holds 30,000 Stock Options and 35,833 shares of Common Stock received from the exercise of options to purchase Common Stock of the Issuer. Dr. Biggar previously served on the Board as a representative of the Funds. The policy of the Funds and the Adviser does not permit employees of the Adviser to receive compensation for serving as a Director of the Issuer. Therefore, Dr. Biggar has no pecuniary interest in any Stock Options or shares of Common Stock directly held by him. The Funds are instead entitled to the pecuniary interest in any Stock Options and shares of Common Stock received as director compensation.
