By attending the meeting virtually, you will be able to participate in the annual meeting, including voting and asking questions. If you are a registered shareholder, you must register in advance to vote and ask questions at the annual meeting.

To register, such shareholders must submit a legal proxy reflecting their CNB common stock holdings along with their name, phone number and email address to VirtualMeeting@viewproxy.com or upload such information to the registration website.

director nominees and the approval of each of the CNB share issuance proposal, the CNB incentive plan proposal, the CNB say-on-pay proposal, the CNB auditor ratification
