Holdings reported include shares acquired in the Umpqua Bank 401(k) and Profit Sharing Plan through dividend reinvestment, payroll deferrals and/or employer contributions. The deferred compensation plan phantom stock was accrued under the Registrant's deferred compensation plan and will be paid in cash in accordance with the terms of the deferred compensation plan following end of the reporting person's employment with the Registrant. A previous Form 5 filed by the reporting person inadvertently underreported the reporting person's deferred compensation plan phantom stock by one share due to an administrative error. /s/ Lisa M.
