The reporting person hereby undertakes to provide to the Securities and Exchange Commission staff, the Issuer, or a security holder of the Issuer, upon request, full information regarding the number of shares sold at each respective price within the range set forth in this footnote.

Remarks: Chief Operating and Business Officer On November 19, 2022, the Issuer entered into an Agreement and Plan of Merger, by and among the Issuer, Merck Sharpe & Dohme LLC and M-Inspire Merger Sub, Inc., providing for the merger of M-Inspire Merger Sub, Inc. with and into the Issuer (the "Merger"), with the Issuer surviving as a wholly owned subsidiary of Merck Sharpe & Dohme LLC. In connection with the Merger, to mitigate the potential impact of Section 280G and Section 4999 of the Internal Revenue Code of 1986, as amended, the Issuer accelerated the exercisability of the reported stock options and vested a portion, allowing the Reporting Person to enter into the transactions disclosed on this Form 4.
