 COLUMBIA BANKING SYSTEM, INC.

 401 Plus Plan 
 Recitals 
  

	A.	Columbia Banking System, Inc. entered into a deferred compensation arrangement with certain of its directors and a select group of senior management and highly
compensated employees and with the directors and a select group of senior management and highly compensated employees of entities with which it is considered a single employer under §§ 414(b) or 414(c) of the U.S. Internal Revenue
Code of 1986, as amended (“Code”). Columbia Banking System, Inc. and such entities are referred to herein, collectively, as the “Company.” 

  

	B.	Such compensation arrangement was governed by the terms of the 401 Plus Plan, dated December 8, 2005. 

  

	C.	Columbia Banking System, Inc. amended and restated the Plan in December 2006, to bring it into compliance with Code § 409A. 

  

	D.	Columbia Banking System, Inc. now wishes to amend and restate the Plan to ensure that all terms and definitions comply with Code § 409A and final
regulations issued thereunder. 

 The Company wishes to memorialize in a written plan document the terms of such arrangement.

 Plan 
  

	I.	Purpose of Plan 

 The
Columbia Banking System, Inc. Deferred Compensation Plan (“Plan”) is intended to provide deferred compensation for the directors and a select group of senior management or highly compensated employees of the Company. 
  

	II.	Participants 

 The Plan
Administrator (defined in Section XIV), in its sole and absolute discretion, shall select the individuals who are permitted to participate in the Plan (“Participants”). The Plan Administrator may only select Participants from among the
directors and the senior management or highly compensated employees of the Company. No individual shall have a right (whether because of his position with the Company, his level of compensation or any other reason whatsoever) to be selected as a
Participant. 
  

 1 









	III.	Election to Defer Compensation 

 A. Amount Deferred. A Participant may elect to defer a fixed dollar amount of Covered Compensation (defined in paragraph IV) earned by him for services performed in a year, which deferred amount shall not exceed fifty percent (50 %)
of base salary and shall not be less than $5,000/year. Notwithstanding anything in the immediately preceding sentence to the contrary, a Participant may elect to defer up to one hundred percent (100%) of any bonus awarded for services performed
in a year and up to one hundred percent (100%) of his fees for services performed in a year as a director of the Company. An election to defer Covered Compensation earned for services performed in a year shall be irrevocable, except to the
extent provided in the Plan. 
 B. Deferral Agreement and Notice. An election to defer Covered Compensation earned by a
Participant for services performed in a year shall be made by delivering to the Company a “Deferral Agreement and Notice” (see Attachment A) duly signed by the Participant. Such “Deferral Agreement and Notice” shall set forth the
percentage or fixed dollar amount of Covered Compensation that the Participant wishes to defer. A Participant may only defer Covered Compensation earned by him for services performed in a year if he delivers to the Company a “Deferral Agreement
and Notice” electing to defer such Covered Compensation in December of the year immediately preceding the year. In the case of the first year in which an individual is selected to be a Participant, he may make an initial election to defer
Covered Compensation paid for services performed after the election in the year by delivering to the Company a “Deferral Agreement and Notice” at least thirty (30) after being selected. 
  

	IV.	Covered Compensation 

 As
used herein, “Covered Compensation” means all cash compensation (including, but not limited to annual salary, bonuses, fees or retainers) earned by an employee or director of the Company for services performed, in such capacity, for the
Company. 
  

	V.	Deferred Compensation Accounts and Funding 

 A. Deferred Compensation Account. The Company shall credit amounts deferred by a Participant under Section III of this Plan by an entry to an account that shall be maintained for such Participant
on its books and records. Such account shall be called the “Deferred Compensation Account” (“DCA”). In addition, the Company shall credit interest to the DCA, as provided in Section VI. 
 B. Plan Un-funded. The Plan is intended to be un-funded for federal income tax purposes and for purposes of Title I of the Employee
Retirement Income Security Act of 1974, as amended from time to time. All monies used to pay amounts credited to the DCA maintained for a Participant shall come from the general funds of the Company.

  

 2 








 
A Participant is an unsecured general creditor of the Company with respect to a DCA maintained for the Participant and shall have no interest, rights or priority in any specific assets of the
Company by reason of this Plan. The Company shall not be required to transfer monies to a separate account, create a separate fund, purchase life insurance or annuity contracts, or make other arrangements to fund its liabilities with respect to a
DCA maintained for a Participant or any other obligations it may have under the Plan. 
 C. Informal Funding. If the
Company, in its sole and absolute discretion, chooses to transfer monies to a separate account, create a separate fund, purchase life insurance or annuity contracts, or make other arrangements to fund its liabilities with respect to a DCA maintained
for a Participant or any other obligations it may have under the Plan, then any such separate account, separate fund, life insurance or annuity contracts, or other arrangements shall remain solely the asset of the Company, subject to the claims of
its unsecured general creditors; and a Participant shall have no interest, rights or priority therein, except as an unsecured general creditor of the Company. 
  

	VI.	Interest Credits to the Deferred Compensation Account 

 A. Interest Crediting Rate. At the time of adoption of the Plan, the agreed upon interest rate shall be equal to the three month LIBOR rate plus 3.58%. The Plan Administrator shall annually review
the calculation of the rate of interest that will be applied to DCAs (the “Interest Crediting Rate”) for appropriateness. The Interest Crediting Rate shall be adjusted quarterly for fluctuations in the three-month LIBOR rate. Plan
participants will be notified of any adjustments to the Interest Crediting Rate. 
 B. Crediting Interest to DCA. On the
last date of each month, the DCA maintained for each Participant shall be credited with an amount equal to the product of (i) one-twelfth (1/12th) of the Interest Crediting Rate for the quarter in which such month occurs, times
(ii) the average balance in the DCA for that month. The amount so credited shall be treated as a part of the credit balance of the DCA for all purposes of this Plan. As used herein, the average balance in a DCA for a month shall be equal
to the quotient determined by dividing (i) the sum of the credit balance in the DCA at the close of business each day in the calendar month, by (ii) the number of days in such month. 
  

	VII.	Plan Distributions 

 A.
Definitions. As used herein, the following capitalized terms shall have the meanings given below: 
 1.
“Designated Beneficiary” means (i) a person that Participant designates on the “Designated Beneficiary Notice” (see Attachment B) as the person entitled to receive, upon Participant’s death, the distributions
that would otherwise be made under the Plan to Participant, or (ii) in the absence of a person so designated by Participant, Participant’s estate. 
  

 3 








 2. “Disabled” means that (i) Participant is unable to
engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment that can be expected to result in death or can be expected to last for a continuous period of not less than twelve (12) months; or
(ii) Participant is, by reason of any medically determinable physical or mental impairment that can be expected to last for a continuous period of not less than twelve (12) months, receiving income replacement benefits for a period
of not less than three (3) months under an accident and health plan covering employees of the Company. 
 3.
“Retire” means Participant’s Separation from Service with the Company, but only if, at the time of such separation, Participant has satisfied all of the following conditions: (i) Participant has attained the age of
fifty-five (55), and (ii) Participant has completed ten (10) years of service as a director and/or employee of the Company. For purposes of the immediately preceding sentence, a Participant shall be credited with one (1) year
of service for each twelve (12) month period of continuous service as a director and/or employee of the Company. 
 4. “Separation from Service” shall have the meaning given to such timer in Treas. Reg. 1.409A-1(h). 
 B.
Distribution Election Notice. At the time a Participant first makes an election to defer Covered Compensation, he shall deliver to the Company a signed “Distribution Election Notice” (see Attachment C) in which he shall elect to
receive distributions of the credit balance in his DCA in the form of either a single lump-sum payment or monthly installment payments over a period not to exceed one hundred twenty (120) months. A Participant may change such election from time
to time, subject to satisfaction of each and every one of the following conditions: 
  

	 	(i)	The change shall not take effect until at least twelve (12) months after the date on which the change is made; 

  

	 	(ii)	All payments affected by the change must be deferred for a period of not less than five (5) years from the date such payments would otherwise have been made (or in
the case of an installment payment five (5) years from the date the first amount was scheduled to be paid); and 

  

	 	(iii)	In the case of a payment at a specified time or pursuant to a fixed schedule, the change cannot be made less than twelve (12) months prior to the date of the first
scheduled payment. 

 C. Distributions Upon Retirement or Disability. The Company shall distribute the
credit balance in a DCA maintained for a Participant at the time he Retires or becomes Disabled as either a single lump-sum or monthly installment payments, as elected by the Participant. If the Participant has elected a single lump-sum
distribution, such distribution shall be made within ninety (90) days after the date that he Retires or becomes Disabled. If the Participant has elected monthly installment payments, such distribution shall be made on the first day of each
month, beginning with the first day of

  

 4 








 
the third month following the month in which he Retires or becomes Disabled and continuing until the full amount of the DCA maintained for him has been distributed. Until such DCA has been
distributed in full, interest shall continue to be credited to the DCA, as provided in Section VI. The monthly installment payments shall be in as nearly equal amounts as possible. Notwithstanding any contrary provisions of the Plan, if Participant
dies after monthly installment payments of the credit balance in the DCA maintained for him have begun, then the remaining credit balance in the DCA shall be distributed to his Designated Beneficiary in a single lump-sum within thirty (30) days
after the Participant’s death. 
 D. Lump Sum Distributions Upon Separation From Service Other Than Because of
Retirement, Upon Death or if DCA is Less Than Specified Amount. Notwithstanding a Participant’s election to receive a distribution of the credit balance in the DCA maintained for him in the form of monthly installment payments, such credit
balance shall be distributed to the Participant or, in the case of clause (ii) below, his Designated Beneficiary, in a single lump-sum within ninety (90) days after the occurrence of any of the following events: 
 (i) Participant experiences a Separation from Service the Company for any reason other than because he Retires or is
Disabled; 
 (ii) Participant dies; or 
 (iii) , After Participant monthly installment payments have begun or are required to begin hereunder, the credit balance of
the DCA maintained for him does not exceed the “applicable dollar amount” (as defined in Code § 402(g)(1)(B)) then in effect, provided that such distribution results in the termination and liquidation of the entirety of the
Participant’s interest under the Plan, including all agreements, methods, programs or other arrangements with respect to which deferrals of compensation are treated as having been deferred under single nonqualified deferred compensation plan
under Treas Reg. § 1.409A-1(c)(2). 
 E. Required Delay in Payments to Specified Employees. If Participant is a
“specified employee” within the meaning of Treas. Reg.§ 1.409A-1(i), then notwithstanding any contrary provisions of the Plan, any amounts payable to the Participant under the Plan on account of a Separation from Service for any
reason that could cause the Participant to be subject to the gross income inclusion, interest and additional tax provisions of Code § 409A(a)(1) shall not be paid until after the end of the sixth calendar month beginning after such
Separation from Service (the “Suspension Period”). Within fourteen (14) calendar days after the end of the Suspension Period, the Company shall pay Participant a lump sum payment in cash equal to any payments delayed because of the
preceding sentence. Thereafter, Participant shall receive any remaining payments under the Plan as if this paragraph E of Section VIII were a not a part of the Plan. 
  

 5 









	VIII.	Change of Control 

 In the
event of a “change in control” of the Company, the Company may, in its sole discretion, establish, on or before the effective date of such change in control, a trust or trusts (“Trust”) to which the Company shall transfer assets
in an amount sufficient to satisfy its obligations under the Plan. Such Trust shall comply with applicable Treasury regulations and rulings in order to qualify as a “rabbi trust.” The principal of the Trust, and any earnings thereon, shall
be held separate and apart from the other assets of the Company and used to discharge of the Company’s obligations under the Plan; provided, however, that such principal and earnings shall continue to be subject to, and may also be used to
satisfy, the claims of the unsecured general creditors of the Company. The term “change in control” shall mean the occurrence of (i) a merger or consolidation in which the Company is not the continuing or surviving entity or
pursuant to which the issued and outstanding shares of common stock of the Company are converted into cash, securities or other property, other than a merger of the Company in which the holders of issued and outstanding shares of the common stock of
the Company immediately prior to the merger have substantially the same proportionate ownership of common stock of the surviving corporation immediately after the merger, (ii) the acquisition of shares of the Company’s issued and
outstanding common stock in a single or a series of related transactions, if immediately thereafter persons who owned shares of such common stock immediately before such acquisition do not own more than fifty percent (50%) of the combined
voting power of the Company immediately after such acquisition, or (iii) the sale, transfer or other disposition of all or substantially all of the assets of the Company. 
  

	IX.	Effect on Other Company Benefit Plans 

 Nothing contained in this Agreement shall affect the right of a Participant to participate in or, be covered by, any other qualified or nonqualified pension, profit sharing, bonus, supplemental
compensation or fringe benefit plans maintained by the Company. 
  

	X.	Assignment or Pledge 

 Except to the extent required by law, a Participant’s rights to any amounts credited to a DCA maintained for the Participant, or to receive any payments under the Plan (i) may not be sold, exchanged, transferred, assigned,
pledged, hypothecated, encumbered or otherwise conveyed by the Participant, (ii) shall not be subject to levy or seizure for the payments of any debts, liabilities or obligations of the Participant (including, without limitation,
judgments against, and child support, alimony or separate maintenance obligations of, the Participant), and (iii) shall not be transferable in the event of the bankruptcy or insolvency of the Participant, to the fullest extent permitted
by law. 
  

	XI.	Employment 

 This Plan
shall not (i) expand or restrict any rights or obligations created under an employment agreement by and between the Company and a Participant, (ii) create specific employment rights in a Participant, (iii) limit
the right of the Company to terminate a Participant’s services or employment with the Company at any time and for any reason whatsoever, or (iv) limit the right of a Participant to terminate his services or employment with the
Company at any time and for any reason whatsoever. 
  

 6 









	XII.	Applicable State Law 

 This Plan shall be construed and interpreted in accordance with the laws of the State of Washington 
  

	XIII.	Amendment and Termination of Plan 

 A. General. The Company shall have the right, in its sole and absolute discretion, to amend or to terminate the Plan at any time; provided, however, that any such amendment or termination shall not reduce the credit balance in a
Participant’s DCA at the time of the amendment or termination or affect the Company’s obligation to distribute to Participant the amount of such credit balance under the terms of the Plan in effect immediately before such amendment or
termination. In the event the Plan is terminated, no additional Covered Compensation shall be deferred. 
 B. Election to
Distribute on Termination. Notwithstanding any contrary provisions contained herein, at any time after the Company terminates the Plan, it may, in its sole and absolute discretion, distribute the credit balance in a Participant’s DCA,
provided that 
  

	 	(i)	The termination and liquidation does not occur proximate in time to a downturn in the financial health of the Company; 

  

	 	(ii)	The Company terminates and liquidates all agreements, methods, programs and other arrangements sponsored by the Company that would be aggregated with any terminated and
liquidated agreements, methods, programs and other arrangements under Treas. Reg. § 1.409A-1(c) if the same Participant had deferrals of compensation under all of the agreements, methods, programs and other arrangements that are terminated
and liquidated; 

  

	 	(iii)	No payments in liquidation of the Plan are made within twelve (12) months of the date the Company takes all necessary action to irrevocably terminate and liquidate
the Plan, other than payments that would be payable under the terms of the Plan if the action to terminate and liquidate the Plan had not occurred; 

  

	 	(iv)	All payment are made within twenty-four (24) months of the date the Company takes all necessary action to irrevocably terminate and liquidate the Plan; and


  

	 	(v)	The Company does not adopt a new plan that would be aggregated with any terminated and liquidated plan under Treas. Reg. § 1.409A-1(c), if the same
Participant participated in both plans, at any time within three (3) years following the date the Company takes all necessary action to irrevocably terminate and liquidate the Plan. 

  

 7 









	XIV.	Miscellaneous 

 A. Plan
Administrator. The Plan shall be administered by the board of directors of the Company (“Board”) or a committee appointed by the Board that shall consist of at least three (3), but less than all, members of the Board. In its sole and
absolute discretion, the Board may, from time to time, change the composition of a committee appointed by it to administer the Plan or dismiss such committee and assume sole responsibility for administering the Plan. The person administering the
Plan, as provided in this Section XIV, shall be referred to as the “Plan Administrator.” The Plan Administrator may employ such advisors and delegate to other persons such responsibilities relating to the Plan as it deems necessary or
advisable. 
 B. Interpretation of Plan. The Plan Administrator shall have the sole and absolute discretion to interpret
the Plan and any agreements entered into in connection therewith, and its interpretation shall be final and binding on all persons. In addition, the Plan Administrator may supply such missing terms to the Plan as it deems reasonably necessary to
carry out is purpose. 
 C. Relationship of Participant, Plan and Company. Nothing contained in this Plan shall be deemed
to create a trust relationship between or among a Participant, the Company and the Plan. 
 D. Statements. Statements
detailing a participant’s contributions to the 401 Plus Plan will be provided on a yearly basis beginning after the first quarter subsequent to implementation of this Plan. 
 E. Unforeseeable Emergency. The Plan is intended to help Participant’s put aside money for their retirement. However, a
distribution may be made to a Participant from his DCA if he experiences an Unforeseeable Emergency. As used herein, the term “Unforeseeable Emergency” means (i) a sever financial hardship resulting from an illness or accident
suffered by him, his spouse, his Designated Beneficiary or his dependent (as defined in Code § 152, but without regard to Code §§ 152(b)(1), (b)2) and (d)(1)(B)); (ii) loss of his property due to casualty; or
(iii) other similar extraordinary and unforeseeable circumstances arising as a result of events beyond his control. Distributions hereunder because of an Unforeseeable Emergency shall be limited to the amount reasonably necessary to
satisfy the emergency need (and may include amounts necessary to pay any Federal, state, local or foreign income taxes or penalties reasonably anticipated to result from the distribution). Determination of the amount reasonably necessary to satisfy
the emergency need must take into account any additional compensation that is available from the cancellation of the Participant’s deferral election under the Plan because of a payment due to an Unforeseeable Emergency. The Plan Administrator
shall have the absolute right and discretion to determine whether or not to make a distribution to a Participant because of an Unforeseeable Emergency, and its 
  

 8 








 
determination in this regard shall be final and binding on all parties. Upon a determination by the Plan Administrator that a distribution should be made to a Participant hereunder because of an
Unforeseeable Emergency, the Participant’s deferral election hereunder shall be cancelled, and not merely postponed or otherwise delayed, for such period of time as the Plan Administrator determines is reasonably necessary to meet the emergency
need and any later deferral election will be subject to the provisions governing an initial deferral election under Treas. Reg. § 1.409A-2(a). This paragraph E of Section XIV is intended to comply with the provisions of Treas. Reg.
§§ 1.409A-3(i)(3) and (j)(4)(viii) and shall be interpreted accordingly. 
 F. Use of Certain Terms. As
required by the context, (i) masculine, feminine and neuter nouns used in the Plan may be substituted for nouns of another gender, and (ii) singular and plural nouns and verbs used in the Plan may be substituted for nouns or
verbs of another number. All references in the Plan to “year” shall be deemed a reference to the calendar year, except for purposes of paragraph A.3 of Section VII or as otherwise required by the context. 
 G. Code § 409A. This Plan is intended to comply with, and shall be interpreted and administered in a manner consistent with,
Code § 409A and regulations issued thereunder. 
  

	XV.	401(k) Make-up Contributions. 

 A. General. At such times as the Company makes nonelective contributions and/or matching contributions with respect to a year (“Plan Year”) of the qualified 401(k) plan adopted, sponsored or maintained by it for the benefit
of its employees, it shall credit to the DCA of each Participant an amount equal to the excess of (i) the amount that it would have contributed on behalf of the Participant to the qualified 401(k) plan as a non-elective contribution and/or
matching contribution for such Plan Year, if the Participant had not elected to defer compensation under the Plan (“Maximum Contribution”), over (ii) the amount that it in fact contributes on behalf of the Participant to the qualified
401(k) plan as a non-elective contribution and/or matching contribution for such Plan Year. 
 B. Maximum Contribution.
For purposes of this Section XV, the Maximum Contribution shall be determined by assuming that: 
 (i) The
Participant does not elect to defer compensation under the Plan; 
 (ii) The compensation that the Participant in
fact defers under the Plan is instead paid to Participant in the Plan Year; and 
 (iii) After giving effect to
clauses (i) and (ii) above, Participant elects to make the maximum elective deferrals that he or she is permitted to make under the Plan for the Plan Year (including “catch-up” contributions under Code § 414(v)).

  

 9 








 C. Limitation. Paragraph A of this Section XV shall not apply in the case of matching
contributions, unless Participant makes the maximum elective deferrals that he or she is in fact permitted to make under the Plan for the Plan Year. 
 D. Application of Other Provisions. Amounts credited to the DCA of a Participant under paragraph A of this Section XV shall be treated as, and subject to the provisions of the Plan in the same
manner as, amounts credited to the DCA of a Participant under paragraph A of Section V (including, without limitation, for purposes of crediting interest at the Interest Crediting Rate).
