EXECUTION COPY

Mr. Jeffrey Smith

Dear Jeff;

Cambridge Bancorp (the "Company" or "Parent") considers it essential to the best interest of its stockholders to foster the continuous employment of key management personnel of the Company and its subsidiary, Cambridge Trust Company (the "Bank''). The Board of Directors of the Company (the "Board") recognizes that, as is the case with many publicly held corporations, the possibility of a Change in Control may exist and that such possibility, and the uncertainty and questions that it may raise among management, may result in the departure or distraction of management personnel to the detriment of the Company and its stockholders.

The Board has determined that appropriate steps should be taken to reinforce and encourage the continued attention and dedication of members of the Company's and the Bank's management, including yourself, to their assigned duties in the face of the potentially disturbing circumstances arising from the possibility of a change in control of the Company. Therefore, in connection with your offer of employment with the Bank, we would like to offer you this Change in Control Agreement (this "Agreement'').

Whenever used in this Agreement, additional capitalized words and phrases have the meanings set forth in Schedule A to this Agreement.

Term of Agreement. This Agreement shall commence on the date hereof and shall continue in effect through December 31, 2024; provided, however, that commencing on January 1, 2025 and each January l thereafter, the term of this Agreement shall automatically be extended for one (1) additional year, unless not later than September 30th of the preceding year the Company shall have given notice that it does not wish to extend this Agreement. However, if a Change in Control or Potential Change in Control of the Company, as applicable, shall have occurred during the original or any extended term of this Agreement, this Agreement shall continue in effect for a period of twelve (12) months beyond the month in which the Change in Control or Potential Change in Control, as applicable, occurred notwithstanding notice from the Company that it does not wish to extend the Agreement. Notwithstanding the foregoing, except upon the occurrence of an event that would constitute Cause under this Agreement, for purposes of extending the term of this Agreement, you will be treated in the same manner as similarly situated executives on the chief executive officer's senior management team.

Potential Change in Control You agree that, subject to the terms and conditions of this Agreement, in the event of a Potential Change in Control you will not voluntarily terminate your employment with the Bank until the earliest of:
