 the merger. The vote on the HomeStreet adjournment proposal is a vote separate and apart from the votes on the HomeStreet share issuance proposal, the HomeStreet articles amendment proposal, the HomeStreet new equity incentive plan proposal and the HomeStreet merger-related compensation proposal. Accordingly, if you are a holder of HomeStreet common stock, you may vote to approve the HomeStreet share issuance proposal, the HomeStreet articles amendment proposal, the HomeStreet new equity incentive plan proposal and/or the HomeStreet merger-related compensation proposal and vote not to approve the HomeStreet adjournment proposal, and vice versa.

Whether or not a quorum is present at the meeting, approval of the HomeStreet adjournment proposal requires that the number of votes cast favoring the HomeStreet adjournment proposal exceeds the number of votes cast opposing the HomeStreet adjournment proposal at the HomeStreet special meeting. If you are present at the HomeStreet special meeting and abstain from voting, or respond by proxy with an “ABSTAIN,” it will have no effect on such proposal. If you are not present at the HomeStreet special meeting, do not respond by proxy and do not provide your bank, broker, trustee or other nominee with instructions, as applicable, it will have no effect on the vote count for such proposal.
