 The
purpose of this Plan is to encourage ownership in Seattle Genetics, Inc., a Delaware corporation (the “Company”), by key personnel whose long-term employment or other service relationship with the Company is considered essential to

reference to the closing price of the Company’s Common Stock as quoted on the applicable date on Nasdaq or the exchange or market with the greatest volume of trading in the Common Stock as of the applicable date, or if the Shares were not
trading on such date, then the closing bid on the applicable date. The Administrator may make a good faith determination that it is reasonable to use one valuation method with respect one type of

Employees that the Committee determines may be “covered employees” in the future shall be made by a Committee of two or more “outside directors” within the meaning of Section 162(m) of the Code. 

iii. Rule 16b-3. To the extent desirable to qualify transactions hereunder as exempt
under Rule 16b-3 promulgated under the Exchange Act (“Rule 16b-3”), Awards to Officers and Directors shall be made by the entire Board or a Committee of two or more “non-employee directors” within the meaning of

 (b) Powers of the Administrator. Subject to the provisions of the Plan and, in the case
of a Committee or delegates acting as the Administrator, subject to the specific duties delegated to such Committee or delegates, the Administrator shall have the authority, in its discretion: 

i. to select the Employees, Consultants and Directors of the Company or its Affiliates to whom Awards are to be granted
hereunder; 
 ii. to determine the number of shares of Common Stock or amount of cash to be covered by each Award
granted hereunder; 







 iii. to determine the type of Award to be granted to the selected Employees,
Consultants and Directors; 
 iv. to approve forms of Award Agreements for use under the Plan; 

v. to determine the terms and conditions, not inconsistent with the terms of the Plan, of any Award granted hereunder.
Such terms and conditions include, but are not limited to, the exercise and/or purchase price (if applicable), the time or times when an Award may be exercised (which may or may not be based on performance criteria), the vesting schedule, any
vesting and/or exercisability acceleration or waiver of forfeiture restrictions, the acceptable forms of consideration, the term, and any restriction or limitation regarding any Award or the Shares relating thereto, based in each case on such
factors as the Administrator, in its sole discretion, shall determine and may be established at the time an Award is granted or thereafter; 

vi. to determine whether and under what circumstances an Option may be settled in cash under Section 8(h) instead of
Common Stock; 
 vii. to correct administrative errors; 

viii. to construe and interpret the terms of the Plan (including sub-plans and Plan addenda) and Awards granted pursuant
to the Plan; 
 ix. to adopt rules and procedures relating to the operation and administration of the Plan to
accommodate the specific requirements of local laws and procedures. Without limiting the generality of the foregoing, the Administrator is specifically authorized (A) to adopt the rules and procedures regarding the conversion of local currency,
withholding procedures and handling of stock certificates which vary with local requirements and (B) to adopt sub-plans and Plan addenda as the Administrator deems desirable, to accommodate foreign laws, regulations and practice; 

x. to prescribe, amend and rescind rules and regulations relating to the Plan, including rules and regulations relating to
sub-plans and Plan addenda; 
 xi. to modify or amend each Award, including, but not limited to, the acceleration of
vesting and/or exercisability, provided, however, that any such amendment is subject to Section 14 of the Plan and except as set forth in that Section, may not impair any outstanding Award unless agreed to in writing by the Participant; 

xii. to allow Participants to satisfy withholding tax amounts by electing to have the Company withhold from the Shares to
be issued upon exercise of an Option or vesting of a Stock Award that number of Shares having a Fair Market Value equal to the amount required to be withheld. The Fair Market Value of the Shares to be withheld shall be determined in such manner and
on such date that the Administrator shall determine or, in the absence of provision otherwise, on the date that the amount of tax to be withheld is to be determined. All elections by a Participant to have Shares withheld for this purpose shall be
made in such form and under such conditions as the Administrator may provide; 







 xiii. to authorize conversion or substitution under the Plan of any or all
stock options, stock appreciation rights or other stock awards held by service providers of an entity acquired by the Company (the “Conversion Awards”). Any conversion or substitution shall be effective as of the close of the
merger, acquisition or other transaction. The Conversion Awards may be Nonstatutory Stock Options or Incentive Stock Options, as determined by the Administrator, with respect to options granted by the acquired entity; provided, however, that with
respect to the conversion of stock appreciation rights in the acquired entity, the Conversion Awards shall be Nonstatutory Stock Options. Unless otherwise determined by the Administrator at the time of conversion or substitution, all Conversion
Awards shall have the same terms and conditions as Awards generally granted by the Company under the Plan; 
 xiv. to
authorize any person to execute on behalf of the Company any instrument required to effect the grant of an Award previously granted by the Administrator; 

xv. to impose such restrictions, conditions or limitations as it determines appropriate as to the timing and manner of any
resales by a Participant or other subsequent transfers by the Participant of any Shares issued as a result of or under an Award, including without limitation, (A) restrictions under an insider trading policy or under any other Company policy
relating to Company stock and stock ownership and (B) restrictions as to the use of a specified brokerage firm for such resales or other transfers; 

xvi. to provide, either at the time an Award is granted or by subsequent action, that an Award shall contain as a term
thereof, a right, either in tandem with the other rights under the Award or as an alternative thereto, of the Participant to receive, without payment to the Company, a number of Shares, cash or a combination thereof, the amount of which is
determined by reference to the value of the Award; and 
 xvii. to make all other determinations deemed necessary or
advisable for administering the Plan and any Award granted hereunder. 
 (c) Effect of Administrator’s
Decision. All decisions, determinations and interpretations by the Administrator regarding the Plan, any rules and regulations under the Plan and the terms and conditions of any Award granted hereunder, shall be final and binding on all
Participants and on all other persons. The Administrator shall consider such factors as it deems relevant, in its sole and absolute discretion, to making such decisions, determinations and interpretations including, without limitation, the
recommendations or advice of any officer or other employee of the Company and such attorneys, consultants and accountants as it may select. 

5. Eligibility. 
 Awards may be
granted to Employees, Consultants and Directors of the Company or any of its Affiliates; provided that Incentive Stock Options may be granted only to Employees of the Company or of a Subsidiary of the Company. 







 6. Term of Plan. 

The Plan originally became effective on December 23, 2007. It shall continue in effect for a term of ten (10) years from the latest
date that the stockholders of the Company approve any amendment to add shares to the Plan, unless terminated earlier under Section 14 of the Plan. 

7. Term of Award. 
 The term of each
Award shall be determined by the Administrator and stated in the Award Agreement. In the case of an Option, the term shall be ten (10) years from the Grant Date or such shorter term as may be provided in the Award Agreement; provided that an
Incentive Stock Option granted to an Employee who on the Grant Date owns stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company or any Subsidiary shall have a term of no more than five
(5) years from the Grant Date. 
 8. Options. 

The Administrator may grant an Option or provide for the grant of an Option, either from time to time in the discretion of the Administrator or
automatically upon the occurrence of specified events, including, without limitation, the achievement of performance goals, the satisfaction of an event or condition within the control of the Awardee or within the control of others. 

(a) Option Agreement. Each Option Agreement shall contain provisions regarding (i) the number of Shares
that may be issued upon exercise of the Option, (ii) the type of Option, (iii) the exercise price of the Shares and the means of payment for the Shares, (iv) the term of the Option, (v) such terms and conditions on the vesting
and/or exercisability of an Option as may be determined from time to time by the Administrator, (vi) restrictions on the transfer of the Option or the Shares issued upon exercise of the Option and forfeiture provisions on either and
(vii) such further terms and conditions, in each case not inconsistent with this Plan as may be determined from time to time by the Administrator. 

(b) Exercise Price. The per share exercise price for the Shares to be issued pursuant to exercise of an
Option shall be determined by the Administrator, subject to the following: 
 i. In the case of an Incentive Stock
Option, the per Share exercise price shall be no less than one hundred percent (100%) of the Fair Market Value per Share on the Grant Date; provided however, that in the case of an Incentive Stock Option granted to an Employee who on the Grant
Date owns stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company or any Subsidiary, the per Share exercise price shall be no less than one hundred ten percent (110%) of the Fair Market
Value per Share on the Grant Date. 
 ii. In the case of a Nonstatutory Stock Option, the per Share exercise price shall
be no less than one hundred percent (100%) of the Fair Market Value per Share on the Grant Date. 

iii. Notwithstanding the foregoing, at the Administrator’s discretion, Conversion Awards may be granted in
substitution and/or conversion of options of an acquired entity, with a per Share exercise price of less than 100% of the Fair Market Value per Share on the date of such substitution and/or conversion. 







 (c) No Option Repricings. Other than in connection with a change in the
Company’s capitalization (as described in Section 14(a) of the Plan), the exercise or strike price of an Option or Stock Appreciation Right may not be reduced without stockholder approval. Additionally, the Administrator will not have the
authority to cancel any outstanding Option or Stock Appreciation Right that has an exercise price or strike price greater than the current Fair Market Value of the Common Stock in exchange for cash or other Awards under the Plan, unless the
stockholders of the Company have approved such an action within twelve months prior to such an event. 

(d) Vesting Period and Exercise Dates. Options granted under this Plan shall vest and/or be exercisable at
such time and in such installments during the period prior to the expiration of the Option’s term as determined by the Administrator. The Administrator shall have the right to make the timing of the ability to exercise any Option granted under
this Plan subject to continued employment, the passage of time and/or such performance requirements as deemed appropriate by the Administrator. At any time after the grant of an Option, the Administrator may reduce or eliminate any restrictions
surrounding any Participant’s right to exercise all or part of the Option. 
 (e) Form of
Consideration. The Participant may pay the exercise price of an Option using any of the following forms of consideration, unless the Administrator determines not to permit such form of consideration at any time including at the time of exercise:

 i. cash; 

ii. check or wire transfer (denominated in U.S. Dollars); 

iii. subject to the Company’s discretion to refuse for any reason and at any time to accept such consideration and
subject to any conditions or limitations established by the Administrator, other Shares held by the Participant which have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which said Option
shall be exercised; 
 iv. consideration received by the Company under a broker-assisted sale and remittance program
acceptable to the Administrator; 
 v. cashless “net exercise” arrangement pursuant to which the Company will
reduce the number of Shares issued upon exercise by the largest whole number of Shares having an aggregate Fair Market Value that does not exceed the aggregate exercise price; provided that the Company shall accept a cash or other payment from the
Participant to the extent of any remaining balance of the exercise price not satisfied by such reduction in the number of whole Shares to be issued; and also provided that Shares will no longer be outstanding under an Option and will not be
exercisable thereafter to the extent that (A) Shares are withheld to pay the exercise price pursuant to a “net exercise,” and (B) the remaining number of whole Shares are delivered to the Participant as a result of such exercise;








 vi. such other consideration and method of payment for the issuance of
Shares to the extent permitted by Applicable Laws; or 
 vii. any combination of the foregoing methods of payment. 

(f) Effect of Termination on Options 

i. Generally. Unless otherwise provided for by the Administrator, upon an Awardee’s Termination of Employment other
than as a result of circumstances described in Sections 8(f)(ii) and (iii) below, any outstanding Option granted to such Awardee, whether vested or unvested, to the extent not theretofore exercised, shall terminate immediately upon the
Awardee’s Termination of Employment; provided, however, that the Administrator may in the Option Agreement specify a period of time (but not beyond the expiration date of the Option) following Termination of Employment during which the Awardee
may exercise the Option as to Shares that were vested and exercisable as of the date of Termination of Employment. To the extent such a period following Termination of Employment is specified, the Option shall automatically terminate at the end of
such period to the extent the Awardee has not exercised it within such period. 
 ii. Disability of
Awardee. Unless otherwise provided for by the Administrator, upon an Awardee’s Termination of Employment as a result of the Awardee’s disability, including Total and Permanent Disability, all outstanding Options granted to such Awardee
that were vested and exercisable as of the date of the Awardee’s Termination of Employment may be exercised by the Awardee until (A) twelve (12) months following Awardee’s Termination of Employment as a result of Awardee’s
disability, including Total and Permanent Disability or (B) the expiration of the term of such Option. If the Participant does not exercise such Option within the time specified, the Option (to the extent not exercised) shall automatically
terminate. 
 iii. Death of Awardee. Unless otherwise provided for by the Administrator, upon an
Awardee’s Termination of Employment as a result of the Awardee’s death or in the event of the death of an Awardee within thirty (30) days following an Awardee’s Termination of Employment, all outstanding Options granted to such
Awardee that were vested and exercisable as of the date of the Awardee’s death, or if earlier the date of Termination of Employment, may be exercised until the earlier of (A) six (6) months following the Awardee’s death or
(B) the expiration of the term of such Option. If an Option is held by the Awardee when he or she dies, such Option may be exercised, to the extent the Option is vested and exercisable, by the beneficiary designated by the Awardee (as provided
in Section 15 of the Plan), the executor or administrator of the Awardee’s estate or, if none, by the person(s) entitled to exercise the Option under the Awardee’s will or the laws of descent or distribution; provided that the Company
need not accept exercise of an Option by such beneficiary, executor or administrator unless the Company has satisfactory evidence of such person’s authority to act as such. If the Option is not so exercised within the time specified, such
Option (to the extent not exercised) shall automatically terminate. 







 iv. Termination for Cause. The Administrator has the authority
to cause all outstanding Options held by an Awardee to terminate immediately in their entirety upon first notification to the Awardee of the Awardee’s Termination of Employment for Cause. If an Awardee’s employment or consulting
relationship with the Company is suspended pending an investigation of whether the Awardee shall be terminated for Cause, the Administrator has the authority to cause all the Awardee’s rights under all outstanding Options to be suspended during
the investigation period in which event the Awardee shall have no right to exercise any outstanding Options. 
 v. Other
Terminations of Employment. The Administrator may provide in the applicable Option Agreement for different treatment of Options upon Termination of Employment of the Awardee than that specified above. 

vi. Extension of Exercise Period. The Administrator shall have full power and authority to extend the period of time for
which an Option is to remain exercisable following an Awardee’s Termination of Employment from the periods set forth in Sections 8(f)(ii) and (iii) above or in the Option Agreement to such greater time as the Board shall deem appropriate,
provided that in no event shall such Option be exercisable later than the date of expiration of the term of such Option as set forth in the Option Agreement. 

(g) Leave of Absence. The Administrator shall have the discretion to determine whether and to what extent the vesting of
Options shall be tolled during any unpaid leave of absence; provided, however, that in the absence of such determination, vesting of Options shall be tolled during any leave that is not a leave required to be provided to the Awardee under Applicable
Law. In the event of military leave, vesting shall toll during any unpaid portion of such leave, provided that, upon an Awardee’s returning from military leave (under conditions that would entitle him or her to protection upon such return under
the Uniform Services Employment and Reemployment Rights Act), he or she shall be given vesting credit with respect to Options to the same extent as would have applied had the Awardee continued to provide services to the Company throughout the leave
on the same terms as he or she was providing services immediately prior to such leave. 
 (h) Buyout Provisions. The
Administrator may at any time offer to buy out for a payment in cash or Shares, an Option previously granted, based on such terms and conditions as the Administrator shall establish and communicate to the Awardee at the time that such offer is made.

 9. Incentive Stock Option Limitations/Terms. 

(a) Eligibility. Only employees (as determined in accordance with Section 3401(c) of the Code and the
regulations promulgated thereunder) of the Company or any of its Subsidiaries may be granted Incentive Stock Options. 

(b) $100,000 Limitation. Notwithstanding the designation “Incentive Stock Option” in an Option
Agreement, if and to the extent that the aggregate Fair Market Value of the Shares with respect to which Incentive Stock Options are exercisable for the first time by the Awardee during any calendar year (under all plans of the Company and any of
its Subsidiaries) exceeds U.S. $100,000, such Options shall be treated as Nonstatutory Stock 







 
Options. For purposes of this Section 9(b), Incentive Stock Options shall be taken into account in the order in which they were granted. The Fair Market Value of the Shares shall be
determined as of the Grant Date. 
 (c) Transferability. An Incentive Stock Option may not be sold,
pledged, assigned, hypothecated, transferred or disposed of in any manner by the Awardee otherwise than by will or the laws of descent and distribution, and, during the lifetime of such Awardee, may only be exercised by the Awardee. If the terms of
an Incentive Stock Option are amended to permit transferability, the Option will be treated for tax purposes as a Nonstatutory Stock Option. The designation of a beneficiary by an Awardee will not constitute a transfer. 

(d) Exercise Price. The per Share exercise price of an Incentive Stock Option shall be determined by the
Administrator in accordance with Section 8(b)(i) of the Plan. 
 (e) Other Terms. Option
Agreements evidencing Incentive Stock Options shall contain such other terms and conditions as may be necessary to qualify, to the extent determined desirable by the Administrator, with the applicable provisions of Section 422 of the Code. 

10. Exercise of Option. 

(a) Procedure for Exercise.  

i. Any Option granted hereunder shall be exercisable according to the terms of the Plan and at such times and under such
conditions as determined by the Administrator and set forth in the respective Option Agreement. 
 ii. An Option shall
be deemed exercised when the Company receives (A) written or electronic notice of exercise (in accordance with the Option Agreement) from the person entitled to exercise the Option; (B) full payment for the Shares with respect to which the
related Option is exercised; and (C) payment of all applicable withholding taxes. 
 iii. An Option may not be
exercised for a fraction of a Share. 
 (b) Rights as a Stockholder. The Company shall issue (or cause to be issued)
such Shares as administratively practicable after the Option is exercised. Shares issued upon exercise of an Option shall be issued in the name of the Participant or, if requested by the Participant, in the name of the Participant and his or her
spouse. Unless provided otherwise by the Administrator or pursuant to this Plan, until the Shares are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote
or receive dividends or any other rights as a stockholder shall exist with respect to the Shares subject to an Option, notwithstanding the exercise of the Option. 

11. Stock Awards. 

(a) Stock Award Agreement. Each Stock Award Agreement shall contain provisions regarding (i) the number
of Shares subject to such Stock Award or a formula for 







 
determining such number, (ii) the purchase price of the Shares, if any, and the means of payment for the Shares, (iii) the performance criteria (including Qualifying Performance
Criteria), if any, and level of achievement versus these criteria that shall determine the number of Shares granted, issued, retainable and/or vested, (iv) such terms and conditions on the grant, issuance, vesting, settlement and/or forfeiture
of the Shares as may be determined from time to time by the Administrator, (v) restrictions on the transferability of the Stock Award and (vi) such further terms and conditions in each case not inconsistent with this Plan as may be
determined from time to time by the Administrator; provided, however, that each Stock Award must have a minimum vesting period of one (1) year from the Grant Date. 

(b) Restrictions and Performance Criteria. The grant, issuance, retention, vesting and/or settlement of each
Stock Award or the Shares subject thereto may be subject to such performance criteria (including Qualifying Performance Criteria) and level of achievement versus these criteria as the Administrator shall determine, which criteria may be based on
financial performance, personal performance evaluations and/or completion of service by the Awardee. Unless otherwise permitted in compliance with the requirements of Code Section 162(m) with respect to an Award intended to comply as
“performance-based compensation” thereunder, the Committee shall establish the Qualifying Performance Criteria applicable to, and the formula for calculating the amount payable under, the Award no later than the earlier of (a) the
date ninety (90) days after the commencement of the applicable performance period, or (b) the date on which 25% of the performance period has elapsed, and in any event at a time when the achievement of the applicable Qualifying Performance
Criteria remains substantially uncertain. 
 (c) Forfeiture. Unless otherwise provided for by the
Administrator, upon the Awardee’s Termination of Employment, the Stock Award and the Shares subject thereto shall be forfeited, provided that to the extent that the Participant purchased or earned any Shares, the Company shall have a right to
repurchase the unvested Shares at such price and on such terms and conditions as the Administrator determines. 

(d) Rights as a Stockholder. Unless otherwise provided by the Administrator in the Award Agreement, the
Participant shall have the rights equivalent to those of a stockholder and shall be a stockholder only after Shares are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company)
to the Participant. Unless otherwise provided by the Administrator, a Participant holding Stock Units shall not be entitled to receive dividend payments or any credit therefore as if he or she was an actual stockholder. 

(e) Stock Appreciation Rights. 

i. General. Stock Appreciation Rights may be granted either alone, in addition to, or in tandem with other Awards
granted under the Plan. The Board may grant Stock Appreciation Rights to eligible Participants subject to terms and conditions not inconsistent with this Plan and determined by the Board. The specific terms and conditions applicable to the
Participant shall be provided for in the Stock Award Agreement. Stock Appreciation Rights shall be exercisable, in whole or in part, at such times as the Board shall specify in the Stock Award Agreement. 







 ii. Exercise of Stock Appreciation Right. Upon the exercise of a Stock
Appreciation Right, in whole or in part, the Participant shall be entitled to a payment in an amount equal to the excess of the Fair Market Value on the date of exercise of a fixed number of Shares covered by the exercised portion of the Stock
Appreciation Right, over the Fair Market Value on the Grant Date of the Shares covered by the exercised portion of the Stock Appreciation Right (or such other amount calculated with respect to Shares subject to the Award as the Board may determine).
The amount due to the Participant upon the exercise of a Stock Appreciation Right shall be paid in such form of consideration as determined by the Board and may be in cash, Shares or a combination thereof, over the period or periods specified in the
Stock Award Agreement. A Stock Award Agreement may place limits on the amount that may be paid over any specified period or periods upon the exercise of a Stock Appreciation Right, on an aggregate basis or as to any Participant. A Stock Appreciation
Right shall be considered exercised when the Company receives written notice of exercise in accordance with the terms of the Stock Award Agreement from the person entitled to exercise the Stock Appreciation Right. 

iii. Nonassignability of Stock Appreciation Rights. Except as determined by the Administrator, no Stock Appreciation
Right shall be assignable or otherwise transferable by the Participant except by will or by the laws of descent and distribution. 
 12. Other Provisions
Applicable to Awards. 
 (a) Non-Transferability of Awards. Unless determined otherwise by the
Administrator, an Award may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by beneficiary designation, will or by the laws of descent or distribution. Subject to Section 9(c), the
Administrator may in its discretion make an Award transferable to an Awardee’s family member or any other person or entity as it deems appropriate. If the Administrator makes an Award transferable, either at the time of grant or thereafter,
such Award shall contain such additional terms and conditions as the Administrator deems appropriate, and any transferee shall be deemed to be bound by such terms upon acceptance of such transfer. 

(b) Qualifying Performance Criteria. For purposes of this Plan, the term “Qualifying Performance
Criteria” shall mean any one or more of the following performance criteria, either individually, alternatively or in any combination, applied to either the Company as a whole or to a business unit, Affiliate or business segment, either
individually, alternatively or in any combination, and measured either annually or cumulatively over a period of years, on an absolute basis or relative to a pre-established target, to previous years’ results or to a designated comparison
group, in each case as specified by the Administrator in the Award: (i) cash flow; (ii) earnings (including gross margin, earnings before interest and taxes, earnings before taxes, and net earnings); (iii) earnings per share;
(iv) growth in earnings or earnings per share; (v) stock price; (vi) return on equity or average stockholders’ equity; (vii) total stockholder return; (viii) return on capital; (ix) return on assets or net assets;
(x) return on investment; (xi) revenue; (xii) income or net income; (xiii) operating income or net operating income, in aggregate or per share; (xiv) operating profit or net operating profit; (xv) operating margin;








 
(xvi) return on operating revenue; (xvii) market share; (xviii) growth in stockholder value relative to the moving average of a peer group index; (xix) strategic plan
development and implementation (including individual performance objectives that relate to achievement of the Company’s or any business unit’s strategic plan); (xx) improvement in workforce diversity; (xxi) growth of revenue,
operating income or net income; (xxii) approval by the U.S. Food and Drug Administration or other regulatory body of a product candidate; and (xxiii) any other similar criteria. The Committee may appropriately adjust any evaluation of
performance under a Qualifying Performance Criteria to exclude any of the following events that occurs during a performance period: (A) asset write-downs; (B) litigation or claim judgments or settlements; (C) the effect of changes in
tax law, accounting principles or other such laws or provisions affecting reported results; (D) accruals for reorganization and restructuring programs and/or other nonrecurring charges; and (E) any gains or losses that are
“unusual” in nature or occur “infrequently” under generally accepted accounting principles or discontinued operations in the Company’s financial statements. 

(c) Certification. Prior to the payment of any compensation under an Award intended to qualify as
“performance-based compensation” under Section 162(m) of the Code, the Committee shall certify the extent to which any Qualifying Performance Criteria and any other material terms under such Award have been satisfied (other than in
cases where such relate solely to the increase in the value of the Common Stock). 
 (d) Discretionary
Adjustments Pursuant to Section 162(m). Notwithstanding satisfaction of any completion of any Qualifying Performance Criteria, to the extent specified at the time of grant of an Award to “covered employees” within
the meaning of Section 162(m) of the Code, the number of Shares, Options or other benefits granted, issued, retainable and/or vested under an Award on account of satisfaction of such Qualifying Performance Criteria may be reduced by the
Committee on the basis of such further considerations as the Committee in its sole discretion shall determine. 

(e) Compliance with Section 409A. Notwithstanding anything to the contrary
contained herein, to the extent that the Administrator determines that any Award granted under the Plan is subject to Code Section 409A and unless otherwise specified in the applicable Award Agreement, the Award Agreement evidencing such Award
shall incorporate the terms and conditions necessary for such Award to avoid the consequences described in Code Section 409A(a)(1), and to the maximum extent permitted under Applicable Law (and unless otherwise stated in the applicable Award
Agreement), the Plan and the Award Agreements shall be interpreted in a manner that results in their conforming to the requirements of Code Section 409A(a)(2), (3) and (4) and any Department of Treasury or Internal Revenue Service
regulations or other interpretive guidance issued under Section 409A (whenever issued, the “Guidance”). Notwithstanding anything to the contrary in this Plan (and unless the Award Agreement provides otherwise, with specific
reference to this sentence), to the extent that a Participant holding an Award that constitutes “deferred compensation” under Section 409A and the Guidance is a “specified employee” (also as defined thereunder), no
distribution or payment of any amount shall be made before a date that is six (6) months following the date of such Participant’s “separation from service” (as defined in Section 409A and the Guidance) or, if earlier, the
date of the Participant’s death. 







 (f) Deferral of Award Benefits. The Administrator may
in its discretion and upon such terms and conditions as it determines appropriate permit one or more Participants whom it selects to (a) defer compensation payable pursuant to the terms of an Award, or (b) defer compensation arising
outside the terms of this Plan pursuant to a program that provides for deferred payment in satisfaction of such other compensation amounts through the issuance of one or more Awards. Any such deferral arrangement shall be evidenced by an Award
Agreement in such form as the Administrator shall from time to time establish, and no such deferral arrangement shall be a valid and binding obligation unless evidenced by a fully executed Award Agreement, the form of which the Administrator has
approved, including through the Administrator’s establishing a written program (the “Program”) under this Plan to govern the form of Award Agreements participating in such Program. Any such Award Agreement or Program shall specify the
treatment of dividends or dividend equivalent rights (if any) that apply to Awards governed thereby, and shall further provide that any elections governing payment of amounts pursuant to such Program shall be in writing, shall be delivered to the
Company or its agent in a form and manner that complies with Code Section 409A and the Guidance, and shall specify the amount to be distributed in settlement of the deferral arrangement, as well as the time and form of such distribution in a
manner that complies with Code Section 409A and the Guidance. 
 13. Adjustments upon Changes in Capitalization, Dissolution, Merger or Asset Sale.

 (a) Changes in Capitalization. Subject to any required action by the stockholders of the Company,
(i) the number and kind of Shares covered by each outstanding Award, (ii) the exercise or purchase (including repurchase) price per Share subject to each such outstanding Award and (iii) each of the Share limitations set forth in
Section 3 of the Plan, shall be proportionately adjusted for any increase or decrease in the number or kind of issued shares resulting from a stock split, reverse stock split, stock dividend, spin-off, combination or reclassification of the
Common Stock, or any other similar increase or decrease in the number of issued shares of Common Stock effected without receipt of consideration by the Company; provided, however, that conversion of any convertible securities of the Company shall
not be deemed to have been “effected without receipt of consideration.” Such adjustment shall be made by the Administrator, whose determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, no
issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of shares of Common Stock
subject to an Award. 
 (b) Dissolution or Liquidation. In the event of the proposed dissolution or
liquidation of the Company, the Administrator shall notify each Participant as soon as practicable prior to the effective date of such proposed transaction. To the extent an Award has not been previously exercised or the Shares subject thereto
issued to the Awardee and unless otherwise determined by the Administrator, an Award will terminate immediately prior to the consummation of the transaction. In addition, the Administrator may provide that any Company repurchase option or forfeiture
applicable to any Shares purchased upon exercise of an Option or covered by a Stock Award shall lapse as to all such Shares, provided the proposed liquidation or dissolution takes place at the time and in the matter contemplated. 







 (c) Change in Control. In the event there is a Change in
Control of the Company, as determined by the Board or a Committee, the Board or Committee may, in its discretion, (i) provide for the assumption or substitution of, or adjustment (including to the number and type of Shares and exercise or
purchase price applicable) to, each outstanding Award; (ii) accelerate the vesting of Options and terminate any restrictions on Stock Awards and/or (iii) provide for termination of Awards as a result of the Change in Control on such terms
and conditions as it deems appropriate, including providing for the cancellation of Awards for a cash or other payment to the Participant. 

For purposes of this Section 13(c), an Award shall be considered assumed, without limitation, if, at the time of issuance
of the stock or other consideration upon a Change in Control, as the case may be, each holder of an Award would be entitled to receive upon exercise of the Award the same number and kind of shares of stock or the same amount of property, cash or
securities as such holder would have been entitled to receive upon the occurrence of the transaction if the holder had been, immediately prior to such transaction, the holder of the number of Shares covered by the Award at such time (after giving
effect to any adjustments in the number of Shares covered by the Award as provided for in Section 13(a)); provided that if such consideration received in the transaction is not solely common stock of the successor corporation, the Administrator
may, with the consent of the successor corporation, provide for the consideration to be received upon exercise of the Award to be solely common stock of the successor corporation equal to the Fair Market Value of the per Share consideration received
by holders of Common Stock in the transaction. 
 In the event of a Change in Control, and if an Awardee’s Awards are
not assumed by the successor corporation or its parent or subsidiary and such successor does not substitute equivalent options or awards for those outstanding under the Plan and the Awardee has not experienced a Termination of Employment without
Cause as of, or has experienced a Termination of Employment without Cause immediately prior to, the effective time of the Change in Control, then such Awards shall become fully vested and exercisable and/or payable as applicable, and all forfeiture
or repurchase restrictions on such Awards shall lapse immediately prior to the effective time of the Change in Control. Upon, or in anticipation of, such Change in Control, the Administrator may cause any and all Awards outstanding under the Plan to
terminate at a specific time in the future and shall give each Awardee the right to exercise such Awards during a period of time as the Administrator, in its sole and absolute discretion, shall determine. The Administrator shall have sole discretion
to determine whether an Award has been assumed by the successor corporation or its parent or subsidiary or whether such successor has substituted equivalent awards for those outstanding under the Plan in connection with a Change in Control subject
to the preceding paragraph. 
 In the event of a Change in Control, if outstanding Awards are assumed or equivalent awards
are substituted by the successor corporation or a parent or subsidiary of such successor corporation, and if at the time of, immediately prior to or within twelve (12) months after, the effective time of such Change in Control, an Awardee
experiences a Termination of Employment without Cause or as a result of a Constructive Termination, then, as of the date of Awardee’s Termination of Employment, the vesting and exercisability of any assumed Option, or any option substituted for
an Option by the 







 
successor corporation or a parent or subsidiary of such successor corporation, held by Awardee at the time of termination, and the lapse of any forfeiture or repurchase restrictions with respect
to any assumed Stock Award, or any stock award substituted for a Stock Award by the successor corporation or a parent or subsidiary of such successor corporation, held by Awardee at the time of termination, shall be accelerated in full. 

14. Amendment and Termination of the Plan. 

(a) Amendment and Termination. The Administrator may amend, alter or discontinue the Plan or any Award
Agreement, but any such amendment shall be subject to approval of the stockholders of the Company in the manner and to the extent required by Applicable Law. To the extent required to comply with Section 162(m), the Company shall seek
re-approval of the Plan from time to time by the stockholders. In addition, without limiting the foregoing, unless approved by the stockholders of the Company, no such amendment shall be made that would: 

i. increase the maximum number of Shares for which Awards may be granted under the Plan, other than an increase pursuant
to Section 13 of the Plan; 
 ii. reduce the minimum exercise prices at which Options may be granted under the Plan
(as set forth in Section 8(b)); 
 iii. result in a repricing of Options or Stock Appreciation Rights; or 

iv. change the class of persons eligible to receive Awards under the Plan. 

(b) Effect of Amendment or Termination. No amendment, suspension or termination of the Plan shall impair the
rights of any Award, unless mutually agreed otherwise between the Participant and the Administrator, which agreement must be in writing and signed by the Participant and the Company; provided further that the Administrator may amend an outstanding
Award in order to conform it to the Administrator’s intent (in its sole discretion) that such Award not be subject to Code Section 409A(a)(1). Termination of the Plan shall not affect the Administrator’s ability to exercise the powers
granted to it hereunder with respect to Awards granted under the Plan prior to the date of such termination. 

(c) Effect of the Plan on Other Arrangements. Neither the adoption of the Plan by the Board or a Committee
nor the submission of the Plan to the stockholders of the Company for approval shall be construed as creating any limitations on the power of the Board or any Committee to adopt such other incentive arrangements as it or they may deem desirable,
including without limitation, the granting of restricted stock or stock options otherwise than under the Plan, and such arrangements may be either generally applicable or applicable only in specific cases. The value of Awards granted pursuant to the
Plan will not be included as compensation, earnings, salaries or other similar terms used when calculating an Awardee’s benefits under any employee benefit plan sponsored by the Company or any Subsidiary except as such plan otherwise expressly
provides. 







 15. Designation of Beneficiary. 

(a) An Awardee may file a written designation of a beneficiary who is to receive the Awardee’s rights pursuant
to Awardee’s Award or the Awardee may include his or her Awards in an omnibus beneficiary designation for all benefits under the Plan. To the extent that Awardee has completed a designation of beneficiary while employed with the Company, such
beneficiary designation shall remain in effect with respect to any Award hereunder until changed by the Awardee to the extent enforceable under Applicable Law. 

(b) Such designation of beneficiary may be changed by the Awardee at any time by written notice. In the event of the death
of an Awardee and in the absence of a beneficiary validly designated under the Plan who is living at the time of such Awardee’s death, the Company shall allow the executor or administrator of the estate of the Awardee to exercise the Award, or
if no such executor or administrator has been appointed (to the knowledge of the Company), the Company, in its discretion, may allow the spouse or one or more dependents or relatives of the Awardee to exercise the Award to the extent permissible
under Applicable Law or if no spouse, dependent or relative is known to the Company, then to such other person as the Company may designate. 

16. No Right to Awards or to Employment. 

No person shall have any claim or right to be granted an Award and the grant of any Award shall not be construed as giving an Awardee the right
to continue in the employ of the Company or its Affiliates. Further, the Company and its Affiliates expressly reserve the right, at any time, to dismiss any Employee, Consultant or Awardee at any time without liability or any claim under the Plan,
except as provided herein or in any Award Agreement entered into hereunder. 
 17. Legal Compliance. 

Shares shall not be issued pursuant to the exercise of an Option or Stock Award unless the exercise of such Option or Stock Award and the
issuance and delivery of such Shares shall comply with Applicable Laws and shall be further subject to the approval of counsel for the Company with respect to such compliance. 

18. Reservation of Shares. 
 The
Company, during the term of this Plan, will at all times reserve and keep available such number of Shares as shall be sufficient to satisfy the requirements of the Plan. 

19. Notice. 
 Any written notice to
the Company required by any provisions of this Plan shall be addressed to the Secretary of the Company and shall be effective when received. 

20. Governing Law; Interpretation of Plan and Awards. 

(a) This Plan and all determinations made and actions taken pursuant hereto shall be governed by the substantive laws, but
not the choice of law rules, of the state of Delaware. 
 (b) In the event that any provision of the Plan or any Award
granted under the Plan is declared to be illegal, invalid or otherwise unenforceable by a court of competent 







 
jurisdiction, such provision shall be reformed, if possible, to the extent necessary to render it legal, valid and enforceable, or otherwise deleted, and the remainder of the terms of the Plan
and/or Award shall not be affected except to the extent necessary to reform or delete such illegal, invalid or unenforceable provision. 

(c) The headings preceding the text of the sections hereof are inserted solely for convenience of reference, and shall not
constitute a part of the Plan, nor shall they affect its meaning, construction or effect. 
 (d) The terms of the Plan and
any Award shall inure to the benefit of and be binding upon the parties hereto and their respective permitted heirs, beneficiaries, successors and assigns. 

(e) All questions arising under the Plan or under any Award shall be decided by the Administrator in its total and absolute
discretion. In the event the Participant believes that a decision by the Administrator with respect to such person was arbitrary or capricious, the Participant may request arbitration with respect to such decision. The review by the arbitrator shall
be limited to determining whether the Administrator’s decision was arbitrary or capricious. This arbitration shall be the sole and exclusive review permitted of the Administrator’s decision, and the Awardee shall as a condition to the
receipt of an Award be deemed to explicitly waive any right to judicial review. 
 (f) Notice of demand for arbitration
shall be made in writing to the Administrator within thirty (30) days after the applicable decision by the Administrator. The arbitrator shall be selected from amongst those members of the Board who are neither Administrators nor Employees. If
there are no such members of the Board, the arbitrator shall be selected by the Board. The arbitrator shall be an individual who is an attorney licensed to practice law in the State of Washington. Such arbitrator shall be neutral within the meaning
of the Commercial Rules of Dispute Resolution of the American Arbitration Association; provided, however, that the arbitration shall not be administered by the American Arbitration Association. Any challenge to the neutrality of the arbitrator shall
be resolved by the arbitrator whose decision shall be final and conclusive. The arbitration shall be administered and conducted by the arbitrator pursuant to the Commercial Rules of Dispute Resolution of the American Arbitration Association. The
decision of the arbitrator on the issue(s) presented for arbitration shall be final and conclusive and may be enforced in any court of competent jurisdiction. 

21. Limitation on Liability. 
 The
Company and any Affiliate which is in existence or hereafter comes into existence shall not be liable to a Participant, an Employee, an Awardee or any other persons as to: 

(a) The Non-Issuance of Shares. The non-issuance or sale of Shares (including under Section 17 above)
as to which the Company has been unable, or the Administrator deems it infeasible, to obtain from any regulatory body having jurisdiction the authority deemed by the Company’s counsel to be necessary to the lawful issuance and sale of any
shares hereunder; and 







 (b) Tax Consequences. Any tax consequence realized by any
Participant, Employee, Awardee or other person due to the receipt, vesting, exercise or settlement of any Option or other Award granted hereunder or due to the transfer of any Shares issued hereunder. The Participant is responsible for, and by
accepting an Award under the Plan agrees to bear, all taxes of any nature that are legally imposed upon the Participant in connection with an Award, and the Company does not assume, and will not be liable to any party for, any cost or liability
arising in connection with such tax liability legally imposed on the Participant. In particular, Awards issued under the Plan may be characterized by the Internal Revenue Service (the “IRS”) as “deferred compensation”
under the Code resulting in additional taxes, including in some cases interest and penalties. In the event the IRS determines that an Award constitutes deferred compensation under the Code or challenges any good faith characterization made by the
Company or any other party of the tax treatment applicable to an Award, the Participant will be responsible for the additional taxes, and interest and penalties, if any, that are determined to apply if such challenge succeeds, and the Company will
not reimburse the Participant for the amount of any additional taxes, penalties or interest that result. 

(c) Forfeiture. The requirement that Participant forfeit an Award, or the benefits received or to be
received under an Award, pursuant to any Applicable Law. 
 22. Unfunded Plan. 

Insofar as it provides for Awards, the Plan shall be unfunded. Although bookkeeping accounts may be established with respect to Awardees who
are granted Stock Awards under this Plan, any such accounts will be used merely as a bookkeeping convenience. The Company shall not be required to segregate any assets which may at any time be represented by Awards, nor shall this Plan be construed
as providing for such segregation, nor shall the Company nor the Administrator be deemed to be a trustee of stock or cash to be awarded under the Plan. Any liability of the Company to any Participant with respect to an Award shall be based solely
upon any contractual obligations which may be created by the Plan; no such obligation of the Company shall be deemed to be secured by any pledge or other encumbrance on any property of the Company. Neither the Company nor the Administrator shall be
required to give any security or bond for the performance of any obligation which may be created by this Plan.
