WITNESSETH

WHEREAS, the Bank and the Executive are parties to the Employment Agreement, dated as of March 1, 2019, by and between the Bank and the Executive (the “Agreement”), which was amended July 16, 2019, and again on January 26, 2023; and

WHEREAS, the Bank and the Executive wish to reflect the transition of the Executive from the positions of President and Chief Executive Officer of the Bank to the position of Chief Executive Officer of the Bank.

NOW, THEREFORE, in consideration of the foregoing and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, and intention to be legally bound hereby, the Bank and the Executive agree as follows:

1.	Effective as of May 29, 2025, Section 1 of the Employment Agreement, Position and Responsibilities, is deleted in its entirety and replaced with the following new Section 1, Position and Responsibilities:

“During the term of this Agreement, the Executive shall serve as a member of the board of directors of the Bank (the “Board of Directors”) and Chief Executive Officer of the Bank. As Chief Executive Officer of the Bank, the Executive shall be responsible for, in coordination with the President of the Bank, the overall management of the Bank, and shall be responsible for establishing the business objectives, policies and strategic plan of the Bank, in conjunction with the Board of Directors. The Executive also shall be responsible for providing leadership and direction to all departments or divisions of the Bank and shall be the primary contact between the Board of Directors and the staff of the Bank. As Chief Executive Officer, the Executive shall report directly to the Board of Directors. The Executive also shall be nominated as a member of the Board of Directors, subject to election by shareholders of the Bank, as the case may be. The Executive also agrees to serve, if elected or appointed, as an officer and/or director of any affiliate of the Bank.”

2.	Effective as of May 29, 2025, Section 4(a)(ii)(A) of the Employment Agreement is deleted in its entirety and replaced with the following new Section 4(a)(ii)(A):

“(A) the failure to appoint the Executive to the position(s) set forth in Section 1 or a material change in the Executive’s function, duties, or responsibilities, which would cause the Executive’s position(s) to become of lesser responsibility, importance,

or scope from the position(s) and responsibilities, importance or scope described in Section 1 (and any material change shall be deemed a continuing breach of this Agreement by the Bank), unless the Executive has agreed to the change in writing. Notwithstanding the foregoing, the Bank and the Executive acknowledge and agree that the Executive’s transition from the positions of President and Chief Executive Officer of the Bank to the position of Chief Executive Officer of the Bank shall not constitute an event of “Good Reason” that would allow the Executive to resign in such a way as to constitute an Event of Termination.”

3.	All other provisions of the Employment Agreement shall remain in full force and in effect as presently written.
