(“VEF4”), Venrock Management IV, LLC (“VM4”), Venrock Partners Management, LLC (“VPM”) and VEF Management IV, LLC (“VEFM” and together with VA4, VP, VEF4, VM4 and VPM, the “Venrock IV Entities”) and (ii) Venrock Healthcare Capital Partners II, L.P.

The Venrock IV Entities and the VHCP Entities are collectively referred to as the “Reporting Persons.” The Reporting Persons expressly disclaim status as a “group” for purposes of this Schedule 13G/A.

(3)

The VHCP Entities beneficially own an aggregate of 2,510,541 shares underlying immediately exercisable warrants. These warrants consist of (i) a warrant to purchase 2,952,442 shares of common stock held by VHCP2 and (ii) a warrant to purchase 1,196,936 shares of common stock held by VHCP Co-2. These warrants are subject to a beneficial ownership limitation pursuant to which the holder is prohibited from exercising these warrants to the extent that the holder (together with its affiliates and any other person acting as a group together with the holder or any of the holder’s affiliates) would beneficially own more than 4.99% of the number of shares of the Issuer’s common stock outstanding immediately after giving effect to the issuance of shares pursuant to the warrant exercise, subject to specified conditions and exceptions. The 2,510,541 shares underlying immediately exercisable warrants reflects the number of shares that may be issued under these warrants that would result in the VHCP Entities having beneficial ownership of 4.99%. The Venrock IV Entities and the VHCP Entities expressly disclaim status as a “group” for purposes of this Schedule 13G/A. However, if the Venrock IV Entities and the VHCP Entities would be deemed to be a “group,” then the aggregate number of shares of common stock underlying immediately exercisable warrants would be 1,497,579, and the percentage of beneficial ownership of the VHCP Entities would be 3.6%.

(4)

The shares included on rows 6, 8 and 9 do not include an aggregate of 962,415 shares of common stock held by the Venrock IV Entities. The VHCP Entities disclaim beneficial ownership over the shares held by the Venrock IV Entities.

(5)

This percentage is calculated based upon (i) 68,703,548 shares of common stock outstanding as of December 24, 2019, as reported in the Issuer’s definitive proxy statement filed with the Securities and Exchange Commission on January 7, 2020 plus (ii) 2,510,541 shares of common stock underlying immediately exercisable warrants held by the Reporting Persons.

(2)

Consists of (i) 2,255,311 shares of common stock beneficially owned by VHCP2, which includes 1,786,346 shares underlying immediately exercisable warrants; (ii) 914,317 shares of common stock beneficially owned by VHCP Co-2, which includes 724,195 shares underlying immediately exercisable warrants; (iii) 349,052 shares of common stock held by VHCP3 and (iv) 34,903 shares of common stock held by VHCP Co-3. The VHCP Entities beneficially own an aggregate of 2,510,541 shares underlying immediately exercisable warrants. These warrants consist of (i) a warrant to purchase 2,952,442 shares of common stock held by VHCP2 and (ii) a warrant to purchase 1,196,936 shares of common stock held by VHCP Co-2. These warrants are subject to a beneficial ownership limitation pursuant to which the holder is prohibited from exercising these warrants to the extent that the holder (together with its affiliates and any other person acting as a group together with the holder or any of the holder’s affiliates) would beneficially own more than 4.99% of the number of shares of the Issuer’s common stock outstanding immediately after giving effect to the issuance of shares pursuant to the warrant exercise, subject to specified conditions and exceptions. The 2,510,541 shares underlying immediately exercisable warrants reflects the number of shares that may be issued under these warrants that would result in the VHCP Entities having beneficial ownership of 4.99%. The Venrock IV Entities and the VHCP Entities expressly disclaim status as a “group” for purposes of this Schedule 13G/A. However, if the Venrock IV Entities and the VHCP Entities would be deemed to be a “group,” then the aggregate number of shares of common stock underlying immediately exercisable warrants would be 1,497,579, and the percentage of beneficial ownership of the VHCP Entities would be 3.6%.
