Effective May 7, 2020, Columbia State Bank (the “Bank”), a wholly owned subsidiary of Columbia Banking System, Inc. (the “Company”), entered into a Change in Control Agreement (the “CIC Agreement”) with Aaron J. Deer, the Executive Vice President and Chief Financial Officer of the Company. The CIC Agreement contains substantially similar terms as the change in control agreements entered into between the Bank and the Company’s other executive officers.

The CIC Agreement has a term of five years and provides that if Mr. Deer’s employment is terminated without Cause or if he resigns for Good Reason within 365 days following a Change in Control (as each capitalized term is defined in the CIC Agreement) or sixty days prior to the public announcement of such Change in Control (provided that the Change in Control occurs within 18 months of his termination of employment), he will be entitled to receive a severance benefit equal to two times his then-current annual base salary, all of his options will vest, all restrictions on his restricted stock awards will lapse and the Bank will reimburse certain COBRA insurance premiums for a limited time following his termination. During his employment and for a period of two years after any severance benefit is paid under the CIC Agreement, Mr. Deer agrees not to compete with the Bank or the Company, nor solicit or interfere with any employee, customer or business relationship of the Bank or the Company.

A copy of the CIC Agreement will be filed as an Exhibit to the Company’s Quarterly Report on Form 10-Q for the fiscal quarter ended June 30, 2020.
