Second Amendment to the Columbia State Bank Supplemental Executive Retirement Plan Agreement, dated as of February 28, 2023, by and between Columbia State Bank and Kumi Baruffi

For purposes of calculating benefits under this Agreement, Executive's "Base Salary" will be frozen at Three Hundred Eighty-Five Thousand Dollars ($385,000) effective as of the date of this Amendment so that any increases to Executive's Base Salary after the date of this Amendment will not be reflected for purposes of determining the benefit under this Agreement. Executive otherwise shall continue to participate in this Agreement (including with respect to vesting service credit) and shall remain eligible for benefits under any other Agreement to which Executive is a party, in accordance with their respective terms and conditions.

To the extent that any paragraph, term, or provision of the Agreement is not specifically amended herein, or in any other amendment thereto, said paragraph, term, or provision shall remain in full force and effect as set forth in said Agreement.

IN WITNESS WHEREOF, the Executive and a duly authorized representative of Columbia State Bank have signed this Amendment as of the written date.
