SECOND AMENDMENT TO EMPLOYMENT AGREEMENT

1.1    The purpose of this Amendment is to amend certain provisions of the Employment Agreement dated effective as of March 24, 2010 between Umpqua and Officer (as previously amended effective as of December 1, 2014, the “Employment Agreement”) in connection with Officer’s promotion to President and Chief Executive Officer of Umpqua Holdings Corporation and Umpqua Bank.

1.2    The duration of the Employment Agreement is hereby amended and extended to December 31, 2021, unless sooner terminated as set forth in the Employment Agreement.

“12.3    IRC 409A. It is intended that payments and benefits made or provided under this Agreement shall comply with Section 409A of the Code or an exemption thereto.

(a)Any payments that qualify for the “short-term deferral” exception, the separation pay exception or another exception under Section 409A of the Code shall be paid under the applicable exception. For purposes of the limitations on nonqualified deferred compensation under Section 409A of the Code, each payment of compensation under this Agreement shall be treated as a separate payment of compensation for purposes of applying the exclusion under Section 409A of the Code for short-term deferral amounts, the separation pay exception or any other exception or exclusion under Section 409A of the Code. All payments to be made upon a termination of employment under this Agreement may only be made upon a “separation from service” under Section 409A of the Code to the extent necessary in order to avoid the imposition of penalty taxes on Officer pursuant to Section 409A of the Code. In the event the payment of nonqualified deferred compensation subject to Section 409A of the Code is contingent on execution of a release of claims and the designated period to execute the release of claims crosses two taxable years, payment of such nonqualified deferred compensation shall be made in the second taxable year. In no event may Officer, directly or indirectly, designate the calendar year of any payment under this Agreement.

(b)    Notwithstanding anything to the contrary in this Agreement, all reimbursements and in-kind benefits provided under this Agreement that are subject to Section 409A of the Code shall be made in accordance with the requirements of Section 409A of the Code, including, where applicable, the requirement that (i) any reimbursement is for expenses incurred during Officer’s lifetime (or during a shorter period of time specified in this Agreement); (ii) the amount of expenses eligible for reimbursement, or in-kind benefits provided, during a calendar year may not affect the expenses eligible for reimbursement, or in-kind benefits to be provided, in any other calendar year; (iii) the reimbursement of an eligible expense will be made no later than the last day of the calendar year following the year in which the expense is incurred; and (iv) the right to reimbursement or in-kind benefits is not subject to liquidation or exchange for another benefit.

(c)     Notwithstanding any other provision of this Agreement to the contrary, if Officer is considered a “specified employee” for purposes of Section 409A of the Code (as determined in accordance with the methodology established by Umpqua as in effect on the date of Officer’s separation from service (as determined in accordance with Section 409A of the Code)), any payment that constitutes nonqualified deferred

compensation within the meaning of Section 409A of the Code that is otherwise due to Officer under this Agreement during the six-month period immediately following Officer’s separation from service on account of Officer’s separation from service shall be accumulated and paid to Officer on the first business day of the seventh month following his separation from service (the “Delayed Payment Date”). If Officer dies during the postponement period, the amounts and entitlements delayed on account of Section 409A of the Code shall be paid either to Officer’s beneficiary or the personal representative of his estate on the first to occur of the Delayed Payment Date or 30 calendar days after the date of Officer’s death.

(d)     Despite any contrary provision of this Agreement, any references to termination of employment or date of termination shall mean and refer to the date of Officer’s “separation from service” as that term is defined in Section 409A of the Code and Treasury Regulation Section 1.409A-1(h).”

“Notwithstanding any other provision of this Agreement: (A) Officer will not be held criminally or civilly liable under any federal or state trade secret law for any disclosure of a trade secret that is made: (1) in confidence to a federal, state, or local government official, either directly or indirectly, or to an attorney and solely for the purpose of reporting or investigating a suspected violation of law; or (2) in a complaint or other document that is filed under seal in a lawsuit or other proceeding; and (B) if Officer files a lawsuit for retaliation by Umpqua for reporting a suspected violation of law, Officer may disclose Umpqua’s trade secrets to Officer’s attorney and use the trade secret information in the court proceeding if Officer (1) files any document containing the trade secret under seal; and (2) does not disclose the trade secret, except pursuant to court order.”
