Types of Awards. The 2025 Plan provides for the grant of options, SARs, restricted stock, RSUs, deferred stock units, unrestricted stock, dividend equivalent rights, and other equity-based awards. 57

Eligibility. All of CNB’s employees and the employees of CNB’s
“subsidiaries” and “affiliates” (as defined in the 2025 Plan) are eligible to receive awards under the 2025 Plan. In addition, CNB’s non-employee directors and consultants and advisors
who perform services for CNB and its subsidiaries and affiliates may receive awards under the 2025 Plan, other than incentive stock options. As of February 10, 2025, there were five named executive officers, nine
non-employee directors, and approximately 278employees of CNB and its subsidiaries who would be eligible to participate in the 2025 Plan.

Shares Reserved for Issuance. The maximum number of shares of common stock that may be issued under the 2025 Plan (the “Share Limit”)
will be equal to the sum of (i) 750,000 shares of CNB common stock, plus (ii) the number of shares of CNB common stock available for future awards under the 2019 Plan as of the Effective Date, plus (iii) the number of shares of CNB common
stock related to awards outstanding under the 2019 Plan as of the Effective Date that thereafter terminate by expiration or forfeiture, cancellation, or otherwise without the issuance of such shares of CNB common stock. The maximum number of shares
of CNB common stock available for issuance pursuant to incentive stock options granted under the Plan will be the same as the number of shares of CNB common stock reserved for issuance under the 2025 Plan. The shares of CNB common stock that are
issued under the 2025 Plan may be authorized and unissued shares of CNB common stock, treasury shares, or any combination of the foregoing.

Share Usage. Shares of CNB common stock that are subject to awards, including shares of stock acquired through dividend reinvestment, will be counted against the Share Limit as one share for every one share subject to the award. The number of
shares subject to any SARs awarded under the 2025 Plan will be counted against the Share Limit regardless of the number of shares actually issued
