| Proposal   |     |                           |     | Votes Necessary                                                                                                                                                                                                  |
| Proposal 1 |     | Merger Agreement Proposal |     | Approval requires the affirmative vote of a majority of the outstanding shares of Kineta Common Stock entitled to vote on the Merger Agreement Proposal. A failure to vote, a broker non-vote                    
 or an abstention will have the same effect as a vote “AGAINST” the Merger Agreement Proposal.                                                                                                                    |
| Proposal 2 |     | Compensation Proposal     |     | Approval requires the affirmative vote of a majority of the votes properly cast for and against the Compensation Proposal (meaning the number of votes cast “FOR” this proposal must exceed the votes cast       
 “AGAINST”). A failure to vote, a broker non-vote or an abstention will have no effect on the outcome of the Compensation Proposal.                                                                               |
| Proposal 3 |     | Adjournment Proposal      |     | Approval requires the affirmative vote of a majority of the votes properly cast for and against the Kineta Adjournment Proposal (meaning the number of votes cast “FOR” this proposal must exceed the votes cast 
 “AGAINST”). A failure to vote, a broker non-vote or an abstention will have no effect on the outcome of the Kineta Adjournment Proposal.                                                                         |
