That agreement provides that each such person will vote its shares of Common Stock in favor of the election of certain director nominees at the Issuer's 2022 annual meeting. By virtue of such agreement, the forgoing persons may be deemed to be part of a "group" (within the meaning of Section 13(d)(3) of the Exchange Act) comprised of such persons. The Reporting Person expressly disclaims beneficial ownership over any Common Stock that he may be deemed to beneficially own solely by reason of the agreement reached among II LP, M28, Polaris, Adimab, LLC and Population Health, and beneficial ownership of any securities of the Issuer other than those previously reported by the Reporting Person on Form 4.
