AND

PARTICIPATION AGREEMENT

WHERAS, TriCo Bancshares (the “Company”) maintains the TriCo Bancshares Supplemental Executive Retirement Plan (the “SERP”);

WHEREAS, Xxxxxxx X. Xxxxx (the “Executive”) became a participant in the SERP pursuant to a participation agreement dated December 14, 1993 (the “Participation Agreement”);

WHEREAS, the Board has determined to amend the SERP with respect to the Executive (and only the Executive) so as to help rationalize the balance between accrued SERP benefits and other compensation by freezing the Executive’s SERP benefit as between two life annuity benefit forms that as of the effective date hereof are actuarially equivalent applying reasonable actuarial methods and assumptions.

Xxxxx shall, effective December 27, 2022, be frozen (the “Benefit Freeze Effective Date”); therefore, commencing on the first day of the month coinciding with or following Xx. Xxxxx’x Normal Retirement Date, the Employer shall:

(i) if at the time of benefit commencement Xx. Xxxxx remains married to his spouse as of the Benefit Freeze Effective Date, pay to Xx. Xxxxx and such spouse a 100% joint & survivor annuity in a monthly Supplemental Retirement Benefit amount equal to $65,416.67 (the equivalent of $785,000 annually), or

(ii) if at the time of benefit commencement Xx. Xxxxx is no longer married to his spouse as of the Benefit Freeze Effective Date (whether due to death or divorce), pay to Xx. Xxxxx a single life annuity in a monthly Supplemental Retirement Benefit equal to $81,250 (the equivalent of $975,000 annually).

2. The SERP is amended, solely with respect to the Executive, by deleting Section 4.6 (“Form of Benefit Payment”) and replacing it in its entirety with the following new language:
