 of record, you may vote by proxy through the Internet, by telephone or by mail, or by voting at the Kineta special meeting via the Kineta special meeting website. For shares held through a bank, broker or other nominee in “street name” instead of as a registered holder, you may vote by submitting your voting instructions to your bank, broker or other nominee. In most instances, you will be able to do this over the Internet, by telephone or by mail as indicated below. Please refer to the information from your bank, broker or other nominee on how to submit voting instructions. If you do not provide voting instructions to your bank, broker or other nominee, your shares of Kineta Common Stock will not be voted on any proposal as your bank, broker or other nominee does not have discretionary authority to vote on any of the proposals to be voted on at the Kineta special meeting; see the section entitled “The Kineta Special Meeting—Quorum; Abstentions and Broker Non-Votes”.
