ARTICLE 1

ESTABLISHMENT AND PURPOSE

1.1 Establishment. Barrett Business Services, Inc. ("Corporation"), hereby establishes the Barrett Business Services, Inc., Amended and Restated 2020 Stock Incentive Plan (the "Plan"), effective on the Effective Date. The original plan had an effective date of May 27, 2020.

1.2 Purpose. The purpose of the Plan is to promote and advance the interests of Corporation and its stockholders by enabling Corporation to attract, retain, and reward key employees, directors, and outside consultants of Corporation and its subsidiaries. It is also intended to strengthen the mutuality of interests between such employees, directors, and consultants and Corporation's stockholders. The Plan is designed to serve these purposes by offering stock options and other equity‑based incentive awards, thereby providing a proprietary interest in pursuing the long‑term growth, profitability, and financial success of Corporation.

1.3 Prior Plans. The Plan will be separate from the Barrett Business Services, Inc., 2015 Stock Incentive Plan (the "2015 Plan"). The adoption of the Plan will neither affect nor be affected by the continued existence of the 2015 Plan, except that after May 27, 2020, no further Awards will be granted under the 2015 Plan. The Plan will also be separate from the Barrett Business Services, Inc., 2009 Stock Incentive Plan, which was previously superseded by the 2015 Plan.

In the discretion of the Committee, any Award may be granted alone, in addition to, or in tandem with other Awards under the Plan.

6.2 General. Subject to the limitations of the Plan, the Committee may cause Corporation to grant Awards to such Participants, at such times, of such types, in such amounts, for such periods, with such option exercise prices, purchase prices, or base prices, and subject to such terms, conditions, limitations, and restrictions as the Committee, in its discretion, deems appropriate. A Participant may receive more than one Award and more than one type of Award under the Plan.

A-6

A-7

Unless the Committee specifically provides otherwise in the Change in Control provision for a specific Award Agreement, Awards will become Vested as of a Change in Control Date only if, or to the extent, such acceleration in the Vesting of the Awards does not result in an "excess parachute payment" within the meaning of Section 280G(b) of the Code. The Committee, in its discretion, may include Change in Control provisions in some Award Agreements and not in others, may include different Change in Control provisions in different Award Agreements, and may include Change in Control provisions for some Awards or some Participants and not for others.

Shares withheld or surrendered as described above will be valued based on their Fair Market Value on the date of the transaction. Any Shares withheld or surrendered with respect to a Reporting Person will be subject to such additional conditions and limitations as the Committee may impose to comply with the requirements of the Exchange Act.

A-8

6.6 Performance Goals. In the event an Award is intended to be performance-based, the Committee will establish Performance Goals for each Performance Period on the basis of such criteria and to accomplish such objectives as the Committee may from time to time select. Performance Goals may be based on (a) performance criteria for the Corporation, a Subsidiary, an operating group, or a branch, (b) a Participant's individual performance, or (c) a combination of both. Performance Goals may include objective and subjective criteria. During any Performance Period, the Committee may adjust the Performance Goals for such Performance Period as it deems equitable in recognition of unusual or nonrecurring events affecting the Corporation, changes in applicable tax laws or accounting principles, or such other factors as the Committee may determine in its sole discretion. Prior to the payment of any Award intended to be performance-based, the Committee must certify, which certification shall be documented in writing, that applicable Performance Goals and any of the material terms thereof were, in fact, satisfied.

6.7 Maximum Awards to Non-Employee Board Directors. Notwithstanding anything to the contrary in this Plan, the value of all Awards awarded under this Plan plus all other cash compensation paid by the Corporation to any Non-Employee Board Director in any calendar year shall not exceed a total of $400,000.

ARTICLE 7
OPTIONS

7.1 Types of Options. Options granted under the Plan may be in the form of Incentive Stock Options or Nonqualified Options. The grant of each Option and the Award Agreement governing each Option will identify the Option as an ISO or an NQO. In the event the Code is amended to provide for tax favored forms of stock options other than or in addition to Incentive Stock Options, the Committee may grant Options under the Plan meeting the requirements of such forms of options. ISOs may not be awarded unless the Plan is approved by stockholders within 12 months of adoption of the Plan.

7.7 Restricted Shares. In the discretion of the Committee, the Shares issuable upon exercise of an Option may have restrictions similar to Restricted Awards if so provided in the Award Agreement for the Option.

ARTICLE 8
STOCK APPRECIATION RIGHTS

8.1 General. Stock Appreciation Rights are subject to the terms and conditions set forth in Article 6 and this Article 8 and Award Agreements governing Stock Appreciation Rights may contain such additional terms and conditions, not inconsistent with the express terms of the Plan, as the Committee deems desirable.

The base price will be designated by the Committee in the Award Agreement for the SAR and may be the Fair Market Value of a Share on the Grant Date of the SAR or such other higher price as the Committee determines. The base price may not be less than the Fair Market Value of a Share on the Grant Date of the SAR.

8.3 Exercise. A Stock Appreciation Right may be exercised by a Participant in accordance with procedures established by the Committee. The Committee may also provide that a SAR will be automatically exercised on one or more specified dates or upon the satisfaction of one or more specified conditions.

ARTICLE 9
RESTRICTED AWARDS

A-10

9.2 General. Restricted Awards are subject to the terms and conditions of Article 6 and this Article 9 and Award Agreements governing Restricted Awards may contain such additional terms and conditions, not inconsistent with the express provisions of the Plan, as the Committee deems desirable.

9.3 Restriction Period. Award Agreements for Restricted Awards will provide that the Shares subject to Restricted Awards may not be transferred, and may provide that, in order for a Participant to Vest in such Restricted Awards, the Participant's Continuous Service must not be terminated, subject to relief for reasons specified in the Award Agreement, for a period commencing on the Grant Date of the Award and ending on such later date or dates as the Committee may designate at the time of the Award (the "Restriction Period"). During the Restriction Period, a Participant may not sell, assign, transfer, pledge, encumber, or otherwise dispose of Shares received under a Restricted Award grant. The Committee, in its sole discretion, may provide for the lapse of restrictions in installments during the Restriction Period. Upon expiration of the applicable Restriction Period (or lapse of Restrictions during the Restriction Period where the Restrictions lapse in installments) the Participant will be entitled to settlement of the Restricted Award or portion thereof, as the case may be.

9.4 Forfeiture. If a Participant's Continuous Service is terminated during the Restriction Period for any reason other than reasons which may be specified in an Award Agreement (such as death or Disability), the Award Agreement may require that all non‑Vested Restricted Shares or RSUs previously granted to the Participant be forfeited and, with respect to Restricted Shares, returned to Corporation.

9.5 Settlement of Restricted Awards.

9.6 Rights as a Stockholder. Until the Restrictions have lapsed with respect to Restricted Shares, a Participant will have voting rights as to such Restricted Shares, but cash dividends or dividend equivalents will not be paid or accrued with respect to such Restricted Shares. Stock dividends issued with respect to non-Vested Shares granted under a Restricted Award will be treated as additional Shares covered by the Restricted Award and will be subject to the same Restrictions. A Participant will have no rights as a stockholder with respect to an Award of RSUs until Shares are issued to the Participant in settlement of the Award.

A-11

ARTICLE 10
PERFORMANCE SHARE AWARDS

10.2 Nature of Performance Shares. Each Performance Share shall represent the right of a Participant to receive an actual Share or Share unit having a value equal to one Share.

10.3 Performance Period. At the time of each Performance Share Award, the Committee shall establish, with respect to each such Award, a Performance Period during which performance shall be measured. There may be more than one Performance Share Award in existence with respect to a given Participant at any one time, and Performance Periods may differ.

10.4 Performance Measures. Performance Shares shall be awarded to a Participant and earned contingent upon the attainment of Performance Goals established in accordance with Section 6.6.

10.5 Payment.

10.5.1 Following the end of the Performance Period, a Participant holding a Performance Share Award will be entitled to receive payment of an amount, not exceeding the maximum value of the Performance Shares, based on the achievement of the Performance Goals for such Performance Period, as determined by the Committee.

10.5.2 Payment of Performance Shares shall be made in cash or Shares, as designated by the Committee in the Award Agreement. Payment shall be made in a lump sum or in installments and shall be subject to such other terms and conditions as shall be determined by the Committee. A Participant shall be paid with respect to the Participant's Performance Shares no later than the last date that causes the payment to constitute a short-term deferral that is not subject to Section 409A, unless the Award Agreement includes terms that comply with Section 409A.

ARTICLE 11
ADJUSTMENTS UPON CHANGES IN CAPITALIZATION, ETC.

11.1 Plan Does Not Restrict Corporation.

11.2 Mandatory Adjustment. In the event of any stock dividend, stock split, reverse stock split, recapitalization, reclassification, or other distribution of Corporation's securities without the receipt of consideration by Corporation, of or on the Common Stock, the Committee shall make proportionate adjustments or substitution to the aggregate number and type of Shares for which Awards may be granted under the Plan, the maximum number and type of Shares which may be sold or awarded to any Participant, the number and type of Shares covered by each outstanding Award, and the base price, exercise price, or purchase price per Share in respect of outstanding Awards.

11.3 Adjustments by the Committee. In the event of any change in capitalization affecting the Common Stock not described in Section 13.2 above, such proportionate adjustments, if any, as the Committee, in its sole discretion, may deem appropriate to reflect such change, will be made with respect to the aggregate number of Shares for which Awards in respect thereof may be granted under the Plan, the maximum number of Shares which may be sold or awarded to any Participant, the number of Shares covered by each outstanding Award, and the base price, exercise price, or purchase price per Share in respect of outstanding Awards. The Committee may also make such adjustments in the number of Shares covered by, and price or other value of, any outstanding Awards in the event of a spin‑off or other distribution (other than normal cash dividends), of Corporation assets to stockholders.

ARTICLE 12
AMENDMENT AND TERMINATION

12.1 Amendment of Plan. The Board at any time, and from time to time, may amend or terminate the Plan; provided that the Plan will terminate 10 years after the Effective Date, if not terminated by the Board on an earlier date. No amendment shall be effective unless approved by the stockholders of the Corporation to the extent stockholder approval is required to satisfy any applicable law or securities exchange listing requirements. At the time of such amendment, the Board shall determine whether such amendment will be contingent on stockholder approval. The Board may, in its sole discretion, submit any other amendment to the Plan for stockholder approval.

12.2 Contemplated Amendments. It is expressly contemplated that the Board may amend the Plan in any respect the Board deems necessary or advisable to provide Participants with the maximum benefits provided or to be provided under the provisions of the Code and the regulations promulgated thereunder relating to Incentive Stock Options or to the nonqualified deferred compensation provisions of Code Section 409A or to bring the Plan or Awards granted under it into compliance therewith.

12.3 No Impairment of Rights. Rights under any Award granted before amendment of the Plan shall not be impaired by any amendment of the Plan unless (a) the Corporation requests the consent of the Participant and (b) the Participant consents in writing. However, an amendment of the Plan that results in a cancellation of an Award where the Participant receives a payment equal in value to the fair market value of the vested Award or, in the case of an Option, the difference between the Fair Market Value and the exercise price for all Shares subject to the Option, shall not be an impairment of the Participant's rights that requires consent of the Participant.

12.4 Amendment of Awards. Subject to Section 12.5, the Committee at any time, and from time to time, may amend the terms of any one or more Awards; provided, however, that if any such amendment impairs a Participant's rights or increases a Participant's obligations under the Participant’s Award or creates or increases a Participant's federal income tax liability with respect to an Award, such amendment shall also be subject to the Participant's consent (provided, however, a cancellation of an Award where the Participant receives a payment equal in value to the fair market value of the Vested Award or, in the case of Vested Options, the difference between the Fair Market Value of the Shares subject to an Option and the exercise price, shall not constitute an impairment of the Participant's rights that requires consent).

12.5 No Repricings or Underwater Buyouts. Except for adjustments made pursuant to Article 13, without the prior approval of the Corporation's stockholders, no Option or SAR granted under the Plan may:

12.5.1 be amended to decrease the exercise price (in the case of an Option) or base price (in the case of a SAR),

12.5.2 be cancelled in exchange for the grant of any new Option or SAR with a lower exercise or base price or any other new Award, or

12.5.3 otherwise be subject to any action that would be treated under accounting rules or otherwise as a "repricing" of such Option or SAR (including a cash buyout or voluntary surrender/subsequent regrant of an underwater Option or SAR).

ARTICLE 13
MISCELLANEOUS

13.1 Tax Withholding. Corporation has the right, prior to and as a condition to settlement of any Award under the Plan, including the delivery or Vesting of Shares or Awards, to require the Participant to remit to the Corporation an amount sufficient to satisfy any federal, state, or local taxes of any kind required by law to be withheld with respect to such settlement or to take such other action as may be necessary in the opinion of Corporation to satisfy all obligations for the payment of such taxes. The recipient of any payment or distribution under the Plan has the obligation to make arrangements satisfactory to Corporation for the satisfaction of any such tax withholding obligations. Corporation will not be required to make any such payment or distribution under the Plan unless such obligations are satisfied.

13.2 Unfunded Plan. The Plan will be unfunded and Corporation will not be required to segregate any assets that may at any time be represented by Awards under the Plan. Any liability of Corporation to any person with respect to any Award under the Plan will be based solely upon any contractual obligations that may be effected

13.5 Annulment of Awards. Any Award Agreement may provide that the grant of an Award payable in cash is revocable until cash is paid in settlement thereof or that grant of an Award payable in Shares is revocable until the Participant becomes entitled to the certificate (or other evidence of ownership) in settlement thereof. In the event a Participant's Continuous Service is terminated due to Termination for Cause, any Award which is revocable will be annulled as of the date of such Termination for Cause.

13.6 Engaging in Competition with Corporation. Any Award Agreement may provide that, if a Participant's Continuous Service is terminated voluntarily and within a period of time (as specified in the Award Agreement) after the date thereof accepts employment with any competitor of (or otherwise engages in competition with) Corporation, the Committee, in its sole discretion, may require such Participant to return to Corporation the economic value of any Award that is realized or obtained (measured at the date of exercise, Vesting, or payment) by such Participant at any time during the period beginning on the date that is six months prior to the date that such Participant's Continuous Service is terminated.

13.7 Other Benefit and Compensation Programs. Payments and other benefits received by a Participant under an Award made pursuant to the Plan are not to be deemed a part of a Participant's regular, recurring compensation for purposes of the termination indemnity or severance pay law of any state or country and will not be included in, or have any effect on, the determination of benefits under any other employee benefit plan or similar arrangement provided by Corporation or a Subsidiary unless expressly so provided by such other plan or arrangements, or except where the Committee expressly determines that an Award or portion of an Award should be included to accurately reflect competitive compensation practices or to recognize that an Award has been made in lieu of a portion of cash compensation. Awards under the Plan may be made in combination with or in tandem with, or as alternatives to, grants, awards, or payments under any other Corporation or Subsidiary plans, arrangements, or programs. The Plan notwithstanding, Corporation or any Subsidiary may adopt such other compensation programs and additional compensation arrangements as it deems necessary to attract, retain, and reward employees and directors for their service with Corporation and its Subsidiaries.

13.8 Securities Law Restrictions. No Shares may be issued under the Plan unless counsel for Corporation is satisfied that such issuance will be in compliance with applicable federal and state securities laws. Certificates for, or other evidence of ownership of, Shares delivered under the Plan may be subject to such stop‑transfer orders and other restrictions as the Committee may deem advisable under the rules, regulations, and other requirements of the Securities and Exchange Commission, any stock exchange or registered securities association upon which the Common Stock is then listed or quoted, and any applicable federal or state securities laws. The Committee may cause a legend or legends to be put on any such certificates to make appropriate reference to such restrictions.

13.9 Continuing Restriction Agreement. Each Participant will, if requested by Corporation and as a condition to issuance of Shares under the Plan upon an Award or exercise of an Award granted under the Plan that results in the issuance of Shares, become a party to and be bound by a stock restriction or other agreement with Corporation containing restrictions on transfer of Shares, including, without limitation, a right of first refusal for the benefit of Corporation, a market stand-off provision, or such other terms as Corporation may reasonably require.

13.10 Governing Law. Except with respect to references to the Code or federal securities laws, the Plan and all actions taken thereunder will be governed by and construed in accordance with the laws of the state of Maryland, without regard to principles of conflicts of laws.
