Explanation of Responses:

Remarks: This Form 4 relates to the series A participating convertible preferred shares (the "Preferred Shares") of Arbutus Biopharma Corp. (the "Issuer"). On July 10, 2019, the board of directors of Roivant Sciences Ltd. ("Roivant") adopted changes to Roivant's internal governance concerning the disposition of the Preferred Shares and other matters relating to oversight of Roivant's business and governance. Following the amendments adopted on July 10, 2019, disposition of the Preferred Shares requires either the approval of a majority of Roivant's board, including (i) at least two directors meeting certain independence criteria (each, an "Independent Director" and, collectively, the "Independent Directors") or, (ii) if there is only one Independent Director, that sole Independent Director. Andrew Lo and Patrick Machado are currently Independent Directors of Roivant. However, the vote of a majority of Roivant's shareholders holding 5% or more of Roivant's shares (other than Vivek Ramaswamy) may override certain decisions of Roivant's board of directors, including with respect to dispositions of Preferred Shares. As a result of these changes, the Reporting Persons and other major shareholders of Roivant no longer have the individual right to veto dispositive decisions of Roivant's board of directors regarding disposition of the Preferred Shares, and so have ceased to have beneficial ownership of the Preferred Shares directly owned by Roivant. Roivant's ownership of the Issuer's Preferred Shares remains unchanged and this filing is not being made as a result of the purchase or sale of Preferred Shares of the Issuer by any party, including the Reporting Persons.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
