Company: ADAPTIVE BIOTECHNOLOGIES CORPORATION 
 Number
of Shares: 56,875 
 Type/Series of Stock: Series C Preferred Stock 

Warrant Price: $2.6374 per share 
 Issue Date:
April 21, 2014 
 Expiration Date: April 21, 2021 See also Section 5.1(b). 

	Credit Facility:	 This Warrant to Purchase Stock (“Warrant”) is issued in connection with that
certain Loan and Security Agreement of even date herewith between Alexandria Equities, LLC and the Company (the “Loan Agreement”). 

THIS WARRANT CERTIFIES THAT, for good and valuable consideration, Alexandria Equities, LLC (together with any successor or permitted assignee
or transferee of this Warrant or of any shares issued upon exercise hereof, “Holder”) is entitled to purchase the number of fully paid and non-assessable shares (the
“Shares”) of the above-stated Type/Series of Stock (the “Class”) of the above-named company (the “Company”) at the above-stated Warrant Price, all as set forth above and as
adjusted pursuant to Section 2 of this Warrant, subject to the provisions and upon the terms and conditions set forth in this Warrant. 

SECTION 1. EXERCISE.  

1.1    Method of Exercise. Holder may at any time and from time to time exercise this Warrant, in whole or in part,
by delivering to the Company the original of this Warrant together with a duly executed Notice of Exercise in substantially the form attached hereto as Appendix 1 and, unless Holder is exercising this Warrant pursuant to a cashless exercise set
forth in Section 1.2, a check, wire transfer of same-day funds (to an account designated by the Company), or other form of payment acceptable to the Company for the aggregate Warrant Price for the Shares
being purchased. 
 1.2    Cashless Exercise. On any exercise of this Warrant, in lieu of payment of the
aggregate Warrant Price in the manner as specified in Section 1.1 above, but otherwise in accordance with the requirements of Section 1.1, Holder may elect to receive Shares equal to the value of this Warrant, or portion hereof as to which
this Warrant is being exercised. Thereupon, 

  
 1 

 
the Company shall issue to the Holder such number of fully paid and non-assessable Shares as are computed using the following formula: 

 

					
		 	X = Y(A-B)/A
			
	 where:
	 		  	
			
		 	X =	  	the number of Shares to be issued to the Holder;
			
		 	Y	  	the number of Shares with respect to which this Warrant is being exercised (inclusive of the Shares surrendered to the Company in payment of the aggregate Warrant Price);
			
		 	A =	  	the Fair Market Value (as determined pursuant to Section 1.3 below) of one Share; and
			
		 	B =	  	the Warrant Price.

 1.3    Fair Market Value. If the Company’s common stock is then traded or
quoted on a nationally recognized securities exchange, inter-dealer quotation system or over-the-counter market (a “Trading Market”) and the
Class is common stock, the fair market value of a Share shall be the closing price or last sale price of a share of common stock reported for the Business Day immediately before the date on which Holder delivers this Warrant together with its
Notice of Exercise to the Company. If the Company’s common stock is not traded in a Trading Market or the Class is not common stock, the Board of Directors of the Company shall determine the fair market value of a Share in its reasonable
good faith judgment. 
 1.4    Delivery of Certificate and New Warrant. Within a reasonable time after Holder
exercises this Warrant in the manner set forth in Section 1.1 or 1.2 above, the Company shall deliver to Holder a certificate representing the Shares issued to Holder upon such exercise and, if this Warrant has not been fully exercised and has
not expired, a new warrant of like tenor representing the Shares not so acquired. 
 1.5    Replacement of
Warrant. On receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant and, in the case of loss, theft or destruction, on delivery of an indemnity agreement reasonably satisfactory in
form, substance and amount to the Company or, in the case of mutilation, on surrender of this Warrant to the Company for cancellation, the Company shall, within a reasonable time, execute and deliver to Holder, in lieu of this Warrant, a new warrant
of like tenor and amount. 
 1.6    Treatment of Warrant Upon Acquisition of Company. 

(a)    Acquisition. For the purpose of this Warrant, “Acquisition” means any transaction or series
of related transactions involving: (i) the sale, lease, exclusive license, or other disposition of all or substantially all of the assets of the Company (ii) any merger or consolidation of the Company into or with another person or entity
(other than a merger or consolidation effected exclusively to change the Company’s domicile), or any other corporate reorganization, in which the shareholders of the Company in their capacity as such immediately prior to such merger,
consolidation or reorganization, own less than a majority of the Company’s (or the surviving or successor entity’s) outstanding voting power immediately after such merger, consolidation or reorganization; or (iii) any sale or other
transfer by the shareholders of the Company of shares representing at least a majority of the Company’s then-total outstanding combined voting power. 

(b)    Treatment of Warrant at Acquisition. In the event of an Acquisition in which the consideration to be
received by the Company’s shareholders consists solely of cash, 

  
 2 

 
solely of Marketable Securities or a combination of cash and Marketable Securities (a “Cash/Public Acquisition”), either (i) Holder shall exercise this Warrant
pursuant to Section 1.1 and/or 1.2 and such exercise will be deemed effective immediately prior to and contingent upon the consummation of such Acquisition or (ii) if Holder elects not to exercise the Warrant, this Warrant will expire
immediately prior to the consummation of such Acquisition. 
 (c)    The Company shall provide Holder with written
notice of its request relating to the Cash/Public Acquisition (together with such reasonable information as Holder may reasonably require regarding the treatment of this Warrant in connection with such contemplated Cash/Public Acquisition giving
rise to such notice), which is to be delivered to Holder not less than seven (7) Business Days prior to the closing of the proposed Cash/Public Acquisition. In the event the Company does not provide such notice, then if, immediately prior to
the Cash/Public Acquisition, the fair market value of one Share (or other security issuable upon the exercise hereof) as determined in accordance with Section 1.3 above would be greater than the Warrant Price in effect on such date, then this
Warrant shall automatically be deemed on and as of such date to be exercised pursuant to Section 1.2 above as to all Shares (or such other securities) for which it shall not previously have been exercised, and the Company shall promptly notify
the Holder of the number of Shares (or such other securities) issued upon such exercise to the Holder and Holder shall be deemed to have restated each of the representations and warranties in Section 4 of the Warrant as the date thereof. 

(d)    Upon the closing of any Acquisition other than a Cash/Public Acquisition defined above, the acquiring, surviving or
successor entity shall assume the obligations of this Warrant, and this Warrant shall thereafter be exercisable for the same securities and/or other property as would have been paid for the Shares issuable upon exercise of the unexercised portion of
this Warrant as if such Shares were outstanding on and as of the closing of such Acquisition, subject to further adjustment from time to time in accordance with the provisions of this Warrant. 

(e)    As used in this Warrant, “Marketable Securities” means securities meeting all of the
following requirements: (i) the issuer thereof is then subject to the reporting requirements of Section 13 or Section 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and is then
current in its filing of all required reports and other information under the Act and the Exchange Act; (ii) the class and series of shares or other security of the issuer that would be received by Holder in connection with the Acquisition were
Holder to exercise this Warrant on or prior to the closing thereof is then traded in Trading Market, and (iii) Holder would be able to publicly re-sell, within six (6) months following the closing of
such Acquisition, all of the issuer’s shares and/or other securities that would be received by Holder in such Acquisition were Holder to exercise this Warrant in full on or prior to the closing of such Acquisition. 

SECTION 2. ADJUSTMENTS TO THE SHARES AND WARRANT PRICE. 

2.1    Stock Dividends, Splits, Etc. If the Company declares or pays a dividend or distribution on the outstanding
shares of the Class payable in common stock or other securities or property (other than cash), then upon exercise of this Warrant, for each Share acquired, Holder shall receive, without additional cost to Holder, the total number and kind of
securities and property which Holder would have received had Holder owned the Shares of record as of the date the dividend or distribution occurred. If the Company subdivides the outstanding shares of the

  
 3 

 
Class by reclassification or otherwise into a greater number of shares, the number of Shares purchasable hereunder shall be proportionately increased and the Warrant Price shall be
proportionately decreased. If the outstanding shares of the Class are combined or consolidated, by reclassification or otherwise, into a lesser number of shares, the Warrant Price shall be proportionately increased and the number of Shares
shall be proportionately decreased. 
 2.2    Reclassification, Exchange, Combinations or Substitution. Upon any
event whereby all of the outstanding shares of the Class are reclassified, exchanged, combined, substituted, or replaced for, into, with or by Company securities of a different class and/or series, then from and after the consummation of such
event, this Warrant will be exercisable for the number, class and series of Company securities that Holder would have received had the Shares been outstanding on and as of the consummation of such event, and subject to further adjustment thereafter
from time to time in accordance with the provisions of this Warrant. The provisions of this Section 2.2 shall similarly apply to successive reclassifications, exchanges, combinations substitutions, replacements or other similar events. 

2.3    No Fractional Share. No fractional Share shall be issuable upon exercise of this Warrant and the number of
Shares to be issued shall be rounded down to the nearest whole Share. If a fractional Share interest arises upon any exercise of the Warrant, the Company shall eliminate such fractional Share interest by paying Holder in cash the amount computed by
multiplying the fractional interest by (i) the fair market value (as determined in accordance with Section 1.3 above) of a full Share, less (ii) the then-effective Warrant Price. 

2.4    Notice/Certificate as to Adjustments. Upon each adjustment of the Warrant Price, Class and/or number of
Shares, the Company, at the Company’s expense, shall notify Holder in writing within a reasonable time setting forth the adjustments to the Warrant Price, Class and/or number of Shares and facts upon which such adjustment is based. The
Company shall, upon written request from Holder, furnish Holder with a certificate of its Chief Financial Officer, including computations of such adjustment and the Warrant Price, Class and number of Shares in effect upon the date of such
adjustment. 
 SECTION 3. REPRESENTATIONS AND COVENANTS OF THE COMPANY. 

3.1    Representations and Warranties. The Company represents and warrants to, and agrees with, the Holder as
follows: 
 (a)    The initial Warrant Price referenced on the first page of this Warrant is not greater than the price
per share at which shares of the Class were sold pursuant to the Company’s Series C Preferred Stock Purchase Agreement, dated as of July 1, 2013. 

(b)    All Shares which may be issued upon the exercise of this Warrant shall, upon issuance pursuant to the terms
hereof, be duly authorized, validly issued, fully paid and non-assessable, and free of any liens and encumbrances except for restrictions on transfer provided for herein, under applicable federal and state
securities laws or created by the Holder. The Company covenants that it shall at all times cause to be reserved and kept available out of its authorized and unissued capital stock such number of shares of the Class, common stock and other securities
as will be sufficient to permit the exercise in full of this Warrant and the conversion of the Shares into common stock or such other securities. 

  
 4 

 (c)    Upon exercise of this Warrant pursuant to the terms hereof, the
Holder shall be entitled to receive, with respect to the Shares, the registration rights set forth in that certain Third Amended and Restated Investors’ Rights Agreement, dated as of April 3, 2014, by and among the Company and certain
holders of the Company’s capital stock (the “IRA”). 
 3.2    Notice of Certain
Events. If the Company proposes at any time to: 
 (a)    declare any dividend or distribution upon the outstanding
shares of the Class or common stock, whether in cash, property, stock, or other securities and whether or not a regular cash dividend; 

(b)    effect any reclassification, exchange, combination, substitution, reorganization or recapitalization of the
outstanding shares of the Class; 
 (c)    effect an Acquisition or to liquidate, dissolve or wind up; or 

(d)    effect an IPO; 

then, in connection with each such event, the Company shall give Holder: 

(1)    in the case of the matters referred to in (a) above at least seven (7) Business Days prior
written notice of the date on which a record will be taken for such dividend or distribution (and specifying the date on which the holders of outstanding shares of the Class will be entitled thereto) or for determining rights to vote, if any,
in respect of the matters referred to in (a) above; 
 (2)    in the case of the matters referred to
in (b) and (c) above at least seven (7) Business Days prior written notice of the date when the same will take place (and specifying the date on which the holders of outstanding shares of the Class will be entitled to exchange their
shares for the securities or other property deliverable upon the occurrence of such event); and 

(3)    with respect to the IPO, at least seven (7) Business Days prior written notice of the date on
which the Company proposes to file its registration statement in connection therewith. 
 Reference is made to Section 1.6(c) whereby this Warrant will
be deemed to be exercised pursuant to Section 1.2 hereof if the Company does not give written notice to Holder of a Cash/Public Acquisition as required by the terms hereof. Company will also provide information requested by Holder that is
reasonably necessary to enable Holder to comply with Holder’s accounting or reporting requirements.

 SECTION 4. REPRESENTATIONS, WARRANTIES OF THE HOLDER.  

The Holder represents and warrants to the Company as follows: 

4.1    Purchase for Own Account. This Warrant and the securities to be acquired upon exercise of this Warrant by
Holder are being acquired for investment for Holder’s account, not as a nominee or agent, and not with a view to the public resale or distribution within the meaning of the Act. Holder also represents that it has not been formed for the
specific purpose of acquiring this Warrant or the Shares. 
 4.2    Disclosure of Information. Holder is aware of
the Company’s business affairs and financial condition and has received or has had full access to all the information it considers necessary or appropriate to make an informed investment decision with respect to the acquisition of this Warrant
and its underlying securities. Holder further has had an opportunity to ask questions and receive answers from the Company regarding the terms and conditions of the offering of this Warrant and its underlying securities and to obtain additional
information (to the extent the Company possessed such information or could acquire it without unreasonable effort or expense) necessary to verify any information furnished to Holder or to which Holder has access. 

4.3    Investment Experience. Holder understands that the purchase of this Warrant and its underlying securities
involves substantial risk. Holder has experience as an investor in securities of companies in the development stage and acknowledges that Holder can bear the economic risk of such Holder’s investment in this Warrant and its underlying
securities and has such knowledge and experience in financial or business matters that Holder is capable of evaluating the merits and risks of its investment in this Warrant and its underlying securities and/or has a preexisting personal or business
relationship with the Company and certain of its officers, directors or controlling persons of a nature and duration that enables Holder to be aware of the character, business acumen and financial circumstances of such persons. 

4.4    Accredited Investor Status. Holder is an “accredited investor” within the meaning of Regulation D
promulgated under the Act. 
 4.5    The Act. Holder understands that this Warrant and the Shares issuable upon
exercise hereof have not been registered under the Act in reliance upon a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of the Holder’s investment intent as expressed herein. Holder
understands that this Warrant and the Shares issued upon any exercise hereof must be held indefinitely unless subsequently registered under the Act and qualified under applicable state securities laws, or unless exemption from such registration and
qualification are otherwise available. Holder is aware of the provisions of Rule 144 promulgated under the Act. 

4.6    Market Stand-off Agreement. The Holder agrees that the Shares shall
be subject to the Market Standoff provisions in Section 2.12 of the IRA. 
 4.7    No Voting Rights. Holder,
as a Holder of this Warrant, will not have any voting rights until the exercise of this Warrant.

at any time and from time to time on or before 6:00 PM, Pacific time, on the Expiration Date and shall be void thereafter. 

(b)    Automatic Cashless Exercise upon Expiration. In the event that, upon the Expiration Date, the fair market
value of one Share (or other security issuable upon the exercise hereof) as determined in accordance with Section 1.3 above is greater than the Warrant Price in effect on such date, then this Warrant shall automatically be deemed on and as of
such date to be exercised pursuant to Section 1.2 above as to all Shares (or such other securities) for which it shall not previously have been exercised, and the Company shall, within a reasonable time, deliver a certificate representing the
Shares (or such other securities) issued upon such exercise to Holder.

securities issuable, directly or indirectly, upon conversion of the Shares, if any) shall be imprinted with a legend in substantially the following form:

OTHERWISE TRANSFERRED UNLESS AND UNTIL REGISTERED UNDER SAID ACT AND LAWS OR IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER, SUCH OFFER, SALE, PLEDGE OR OTHER TRANSFER IS EXEMPT FROM SUCH REGISTRATION. 

5.3    Compliance with Securities Laws on Transfer. This Warrant and the Shares issuable upon exercise of this
Warrant may not be transferred or assigned in whole or in part except in compliance with applicable federal and state securities laws by the transferor and the transferee (including, without limitation, the delivery of investment representation
letters and legal opinions reasonably satisfactory to the Company, as reasonably requested by the Company). The Company shall not require Holder to provide an opinion of counsel if the transfer is to an affiliate of Holder, provided that any such
transferee is an “accredited investor” as defined in Regulation D promulgated under ,the Act. Additionally, the Company shall also not require an opinion of counsel if there is no material question as to the availability of Rule 144
promulgated under the Act.

providing the Company with written notice, the Holder and any subsequent Holder may transfer all or part of this Warrant or the Shares issuable upon exercise of this Warrant to any transferee, provided, however, in connection with any such transfer,
the Holder or any subsequent Holder will

Company for reissuance to the transferee(s) (and Holder if applicable); and provided further, that any subsequent transferee shall agree in writing with the Company to be bound by all of the terms and conditions of this Warrant. Notwithstanding any
contrary provision herein, at all times prior to the IPO, Holder may not, without the Company’s prior written consent, transfer this Warrant or any portion hereof, or any Shares issued upon any exercise hereof, to any person or entity who

good faith and in the exercise of its discretion whether an individual has become or has ceased to be an Employee and the effective date of such individual’s employment or termination of employment, as the case may be. For purposes of an
individual’s rights, if any, under the terms of the Plan as of the time of the Company’s determination of whether or not the individual is an Employee, all such determinations by the Company shall be final, binding and conclusive as to

the Company is delegated shall be indemnified by the Company against all reasonable expenses, including attorneys’ fees, actually and necessarily incurred in connection with the defense of any action, suit or proceeding, or in connection with
any appeal therein, to which they or any of them may be a party by reason of any action taken or failure to act under or in connection with the Plan, or any right granted hereunder, and against all amounts paid by them in settlement thereof
(provided such settlement is approved by independent legal counsel selected by the Company) or paid by them in satisfaction of a judgment in any such action, suit or proceeding, except in relation to matters as to which it shall be adjudged in such
action, suit or proceeding that such person is liable for gross negligence, bad faith or intentional misconduct in duties; provided, however, that within sixty (60) days after the institution of such action, suit or proceeding, such person
shall offer to the Company, in writing, the opportunity at its own expense to handle and defend the same. 

4.    SHARES SUBJECT TO
PLAN. 
 4.1    Maximum Number of Shares
Issuable. Subject to adjustment as provided in Sections 4.2 and 4.3, the maximum aggregate number of shares of Stock that may be issued under the Plan shall be equal to five million three hundred eighty three thousand two hundred seventy
four (5,383,274) and shall consist of authorized but unissued or reacquired shares of Stock or any combination thereof. 

  
 10 

 4.2    Share Counting. If an outstanding Award for any reason
expires or is terminated or canceled without having been exercised or settled in full, or if shares of Stock acquired pursuant to an Award subject to forfeiture or repurchase are forfeited or repurchased by the Company for an amount not greater than
the Participant’s purchase price, the shares of Stock allocable to the terminated portion of such Award or such forfeited or repurchased shares of Stock shall again be available for issuance under the Plan. Shares of Stock shall not be deemed
to have been issued pursuant to the Plan with respect to any portion of an Award that is settled in cash. Upon payment in shares of Stock pursuant to the exercise of an SAR, the number of shares available for issuance under the Plan shall be reduced
by the gross number of shares for which the SAR is exercised. If the exercise price of an Option is paid by tender to the Company, or attestation to the ownership, of shares of Stock owned by the Participant, or by means of a Net-Exercise, the number of shares available for issuance under the Plan shall be reduced by the gross number of shares for which the Option is exercised. Shares withheld or reacquired by the Company in satisfaction
of tax withholding obligations pursuant to Section 16.2 shall not again be available for issuance under the Plan. 

4.3    Adjustments for Changes in Capital Structure. Subject to any required action by the
stockholders of the Company and the requirements of Sections 409A and 424 of the Code to the extent applicable, in the event of any change in the Stock effected without receipt of consideration by the Company, whether through merger, consolidation,
reorganization, reincorporation, recapitalization, reclassification, stock dividend, stock split, reverse stock split, split-up, split-off, spin-off, combination of shares, exchange of shares, or similar change in the capital structure of the Company, or in the event of payment of a dividend or distribution to the stockholders of the Company in a form
other than Stock (excepting normal cash dividends) that has a material effect on the Fair Market Value of shares of Stock, appropriate and proportionate adjustments shall be made in the number and kind of shares subject to the Plan and to any
outstanding Awards, in the Award limits set forth in Section 5.3 and in the exercise or purchase price per share under any outstanding Award in order to prevent dilution or enlargement of Participants’ rights under the Plan. For purposes
of the foregoing, conversion of any convertible securities of the Company shall not be treated as “effected without receipt of consideration by the Company.” If a majority of the shares which are of the same class as the shares that are
subject to outstanding Awards are exchanged for, converted into, or otherwise become (whether or not pursuant to an Ownership Change Event) shares of another corporation (the “New Shares”), the Committee may
unilaterally amend the outstanding Awards to provide that such Awards are for New Shares. In the event of any such amendment, the number of shares subject to, and the exercise or purchase price per share of, the outstanding Awards shall be adjusted
in a fair and equitable manner as determined by the Committee, in its discretion. Any fractional share resulting from an adjustment pursuant to this Section shall be rounded down to the nearest whole number, and in no event may the exercise or
purchase price under any Award be decreased to an amount less than the par value, if any, of the stock subject to such Award. The Committee in its discretion, may also make such adjustments in the terms of any Award to reflect, or related to, such
changes in the capital structure of the Company or distributions as it deems appropriate, including modification of Performance Goals, Performance Award Formulas and Performance Periods. The adjustments determined by the Committee pursuant to this
Section shall be final, binding and conclusive. 

  
 11 

 The Committee may, without affecting the number of shares of Stock reserved or available
hereunder, authorize the issuance or assumption of benefits under this Plan in connection with any merger, consolidation, acquisition of property or stock, or reorganization upon such terms and conditions as it may deem appropriate, subject to
compliance with Section 409A and any other applicable provisions of the Code. 

5.    ELIGIBILITY, PARTICIPATION AND AWARD
LIMITATIONS. 
 5.1    Persons Eligible for
Awards. Awards may be granted only to Employees, Consultants and Directors. 
 5.2    Participation in the
Plan. Awards are granted solely at the discretion of the Committee. Eligible persons may be granted more than one Award. However, eligibility in accordance with this Section shall not entitle any person to be granted an Award, or, having been
granted an Award, to be granted an additional Award. 
 5.3    Incentive Stock Option Limitations. 

(a)    Maximum Number of Shares Issuable Pursuant to Incentive Stock Options. Subject to adjustment as
provided in Sections 4.2 and 4.3, the maximum aggregate number of shares of Stock that may be issued under the Plan pursuant to the exercise of Incentive Stock Options shall not exceed five million three hundred eighty three thousand two
hundred seventy four (5,383,274). The maximum aggregate number of shares of Stock that may be issued under the Plan pursuant to all Awards other than Incentive Stock Options shall be the number of shares determined in accordance with
Section 4.1, subject to adjustment as provided in Sections 4.2 and 4.3. 
 (b)    Persons
Eligible. An Incentive Stock Option may be granted only to a person who, on the effective date of grant, is an Employee of the Company, a Parent Corporation or a Subsidiary Corporation (each being an “ISO-Qualifying Corporation”). Any person who is not an Employee of an ISO-Qualifying Corporation on the effective date of the grant of an Option to such
person may be granted only a Nonstatutory Stock Option. 
 (c)    Fair Market Value Limitation. To the
extent that options designated as Incentive Stock Options (granted under all stock option plans of the Participating Company Group, including the Plan) become exercisable by a Participant for the first time during any calendar year for stock having
a Fair Market Value greater than One Hundred Thousand Dollars ($100,000), the portion of such options which exceeds such amount shall be treated as Nonstatutory Stock Options. For purposes of this Section, options designated as Incentive Stock
Options shall be taken into account in the order in which they were granted, and the Fair Market Value of stock shall be determined as of the time the option with respect to such stock is granted. If the Code is amended to provide for a limitation
different from that set forth in this Section, such different limitation shall be deemed incorporated herein effective as of the date and with respect to such Options as required or permitted by such amendment to the Code. If an Option is treated as
an Incentive Stock Option in part and as a Nonstatutory Stock Option in part by reason of the limitation set forth in this Section, the Participant may designate which portion of such Option the Participant is exercising. In the absence of such
designation, the Participant shall be deemed to have exercised the Incentive Stock Option portion of the Option first. Upon exercise, shares issued pursuant to each such portion shall be separately identified. 

  
 12 

 6.    STOCK
OPTIONS. 
 Options shall be evidenced by Award Agreements specifying the
number of shares of Stock covered thereby, in such form as the Committee shall from time to time establish. Award Agreements evidencing Options may incorporate all or any of the terms of the Plan by reference and shall comply with and be subject to
the following terms and conditions: 
 6.1    Exercise Price. The exercise price for each Option shall be
established in the discretion of the Committee; provided, however, that (a) the exercise price per share shall be not less than the Fair Market Value of a share of Stock on the effective date of grant of the Option and (b) no Incentive
Stock Option granted to a Ten Percent Owner shall have an exercise price per share less than one hundred ten percent (110%) of the Fair Market Value of a share of Stock on the effective date of grant of the Option. Notwithstanding the foregoing, an
Option (whether an Incentive Stock Option or a Nonstatutory Stock Option) may be granted with an exercise price lower than the minimum exercise price set forth above if such Option is granted pursuant to an assumption or substitution for another
option in a manner qualifying under the provisions of Section 424(a) of the Code. 
 6.2    Exercisability and
Term of Options. Options shall be exercisable at such time or times, or upon such event or events, and subject to such terms, conditions, performance criteria and restrictions as shall be determined by the Committee and set forth in the Award
Agreement evidencing such Option; provided, however, that (a) no Option shall be exercisable after the expiration of ten (10) years after the effective date of grant of such Option and (b) no Incentive Stock Option granted to a Ten
Percent Owner shall be exercisable after the expiration of five (5) years after the effective date of grant of such Option. Subject to the foregoing, unless otherwise specified by the Committee in the grant of an Option, each Option shall
terminate ten (10) years after the effective date of grant of the Option, unless earlier terminated in accordance with its provisions. 

6.3    Payment of Exercise Price. 

(a)    Forms of Consideration Authorized. Except as otherwise provided below, payment of the exercise price
for the number of shares of Stock being purchased pursuant to any Option shall be made (i) in cash, by check or in cash equivalent, (ii) by tender to the Company, or attestation to the ownership, of shares of Stock owned by the Participant
having a Fair Market Value not less than the exercise price, (iii) by delivery of a properly executed notice of exercise together with irrevocable instructions to a broker providing for the assignment to the Company of the proceeds of a sale or
loan with respect to some or all of the shares being acquired upon the exercise of the Option (including, without limitation, through an exercise complying with the provisions of Regulation T as promulgated from time to time by the Board of
Governors of the Federal Reserve System) (a “Cashless Exercise”), (iv) by delivery of a properly executed notice electing a Net-Exercise, (v) by such other
consideration as may be approved by the Committee from time to time to the extent permitted by applicable law, or (vi) by any combination thereof. The Committee may at any time or from time to time grant Options which do not permit all of the
foregoing forms of consideration to be used in payment of the exercise price or which otherwise restrict one or more forms of consideration. 

  
 13 

 (b)    Limitations on Forms of Consideration. 

(i)    Tender of Stock. Notwithstanding the foregoing, an Option may not be exercised by tender to the Company, or
attestation to the ownership, of shares of Stock to the extent such tender or attestation would constitute a violation of the provisions of any law, regulation or agreement restricting the redemption of the Company’s stock. Unless otherwise
provided by the Committee, an Option may not be exercised by tender to the Company, or attestation to the ownership, of shares of Stock unless such shares either have been owned by the Participant for such period of time, if any, as the Company may
require (and not used for another Option exercise by attestation during such period) or were not acquired, directly or indirectly, from the Company. 

(ii)    Cashless Exercise. The Company reserves, at any and all times, the right, in the Company’s sole and
absolute discretion, to establish, decline to approve or terminate any program or procedures for the exercise of Options by means of a Cashless Exercise, including with respect to one or more Participants specified by the Company notwithstanding
that such program or procedures may be available to other Participants. 
 6.4    Effect of Termination of
Service. 
 (a)    Option Exercisability. Subject to earlier termination of the Option as otherwise
provided herein and unless otherwise provided by the Committee, an Option shall terminate immediately upon the Participant’s termination of Service to the extent that it is then unvested and shall be exercisable after the Participant’s
termination of Service to the extent it is then vested only during the applicable time period determined in accordance with this Section and thereafter shall terminate. 

(i)    Disability. If the Participant’s Service terminates because of the Disability of the Participant, the
Option, to the extent unexercised and exercisable for vested shares on the date on which the Participant’s Service terminated, may be exercised by the Participant (or the Participant’s guardian or legal representative) at any time prior to
the expiration of twelve (12) months after the date on which the Participant’s Service terminated, but in any event no later than the date of expiration of the Option’s term as set forth in the Award Agreement evidencing such Option
(the “Option Expiration Date”). 
 (ii)    Death. If the
Participant’s Service terminates because of the death of the Participant, the Option, to the extent unexercised and exercisable for vested shares on the date on which the Participant’s Service terminated, may be exercised by the
Participant’s legal representative or other person who acquired the right to exercise the Option by reason of the Participant’s death at any time prior to the expiration of twelve (12) months after the date on which the
Participant’s Service terminated, but in any event no later than the Option Expiration Date. The Participant’s Service shall be deemed to have terminated on account of death if the Participant dies within three (3) months after the
Participant’s termination of Service. 

  
 14 

 (iii)    Termination for Cause. Notwithstanding any other
provision of the Plan to the contrary, if the Participant’s Service is terminated for Cause or if, following the Participant’s termination of Service and during any period in which the Option otherwise would remain exercisable, the
Participant engages in any act that would constitute Cause, the Option shall terminate in its entirety and cease to be exercisable immediately upon such termination of Service or act. 

(iv)    Other Termination of Service. If the Participant’s Service terminates for any reason, except
Disability, death or Cause, the Option, to the extent unexercised and exercisable for vested shares on the date on which the Participant’s Service terminated, may be exercised by the Participant at any time prior to the expiration of three
(3) months after the date on which the Participant’s Service terminated, but in any event no later than the Option Expiration Date. 

(b)    Extension if Exercise Prevented by Law. Notwithstanding the foregoing, other than termination of
Service for Cause, if the exercise of an Option within the applicable time periods set forth in Section 6.4(a) is prevented by the provisions of Section 14 below, the Option shall remain exercisable until the later of (i) thirty
(30) days after the date such exercise first would no longer be prevented by such provisions or (ii) the end of the applicable time period under Section 6.4(a), but in any event no later than the Option Expiration Date. 

6.5    Transferability of Options. During the lifetime of the Participant, an Option shall be exercisable only by
the Participant or the Participant’s guardian or legal representative. An Option shall not be subject in any manner to anticipation, alienation, sale, exchange, transfer, assignment, pledge, encumbrance, or garnishment by creditors of the
Participant or the Participant’s beneficiary, except transfer by will or by the laws of descent and distribution. Notwithstanding the foregoing, to the extent permitted by the Committee, in its discretion, and set forth in the Award Agreement
evidencing such Option, an Option shall be assignable or transferable subject to the applicable limitations, if any, described in the General Instructions to Form S-8 under the Securities Act or, in the
case of an Incentive Stock Option, only as permitted by applicable regulations under Section 421 of the Code in a manner that does not disqualify such Option as an Incentive Stock Option. 

7.    STOCK APPRECIATION
RIGHTS. 
 Stock Appreciation Rights shall be evidenced by Award
Agreements specifying the number of shares of Stock subject to the Award, in such form as the Committee shall from time to time establish. Award Agreements evidencing SARs may incorporate all or any of the terms of the Plan by reference and shall
comply with and be subject to the following terms and conditions: 
 7.1    Types of SARs Authorized. SARs may be
granted in tandem with all or any portion of a related Option (a “Tandem SAR”) or may be granted independently of any Option (a “Freestanding SAR”). A Tandem SAR may only be
granted concurrently with the grant of the related Option. 

  
 15 

 7.2    Exercise Price. The exercise price for each SAR shall be
established in the discretion of the Committee; provided, however, that (a) the exercise price per share subject to a Tandem SAR shall be the exercise price per share under the related Option and (b) the exercise price per share subject to
a Freestanding SAR shall be not less than the Fair Market Value of a share of Stock on the effective date of grant of the SAR. 

7.3    Exercisability and Term of SARs. 

(a)    Tandem SARs. Tandem SARs shall be exercisable only at the time and to the extent, and only to the
extent, that the related Option is exercisable, subject to such provisions as the Committee may specify where the Tandem SAR is granted with respect to less than the full number of shares of Stock subject to the related Option. The Committee may, in
its discretion, provide in any Award Agreement evidencing a Tandem SAR that such SAR may not be exercised without the advance approval of the Company and, if such approval is not given, then the Option shall nevertheless remain exercisable in
accordance with its terms. A Tandem SAR shall terminate and cease to be exercisable no later than the date on which the related Option expires or is terminated or canceled. Upon the exercise of a Tandem SAR with respect to some or all of the shares
subject to such SAR, the related Option shall be canceled automatically as to the number of shares with respect to which the Tandem SAR was exercised. Upon the exercise of an Option related to a Tandem SAR as to some or all of the shares subject to
such Option, the related Tandem SAR shall be canceled automatically as to the number of shares with respect to which the related Option was exercised. 

(b)    Freestanding SARs. Freestanding SARs shall be exercisable at such time or times, or upon such event
or events, and subject to such terms, conditions, performance criteria and restrictions as shall be determined by the Committee and set forth in the Award Agreement evidencing such SAR; provided, however, that no Freestanding SAR shall be
exercisable after the expiration of ten (10) years after the effective date of grant of such SAR. 

7.4    Exercise of SARs. Upon the exercise (or deemed exercise pursuant to Section 7.5) of an SAR, the
Participant (or the Participant’s legal representative or other person who acquired the right to exercise the SAR by reason of the Participant’s death) shall be entitled to receive payment of an amount for each share with respect to which
the SAR is exercised equal to the excess, if any, of the Fair Market Value of a share of Stock on the date of exercise of the SAR over the exercise price. Payment of such amount shall be made (a) in the case of a Tandem SAR, solely in shares of
Stock in a lump sum upon the date of exercise of the SAR and (b) in the case of a Freestanding SAR, in cash, shares of Stock, or any combination thereof as determined by the Committee, in a lump sum upon the date of exercise of the SAR. When
payment is to be made in shares of Stock, the number of shares to be issued shall be determined on the basis of the Fair Market Value of a share of Stock on the date of exercise of the SAR. For purposes of Section 7, an SAR shall be deemed
exercised on the date on which the Company receives notice of exercise from the Participant or as otherwise provided in Section 7.5. 

7.5    Deemed Exercise of SARs. If, on the date on which an SAR would otherwise terminate or expire, the SAR by its
terms remains exercisable immediately prior to such termination or expiration and, if so exercised, would result in a payment to the holder of such SAR, then any portion of such SAR which has not previously been exercised shall automatically be
deemed to be exercised as of such date with respect to such portion. 

  
 16 

 7.6    Effect of Termination of Service. Subject to earlier
termination of the SAR as otherwise provided herein and unless otherwise provided by the Committee, an SAR shall be exercisable after a Participant’s termination of Service only to the extent and during the applicable time period determined in
accordance with Section 6.4 (treating the SAR as if it were an Option) and thereafter shall terminate. 

7.7    Transferability of SARs. During the lifetime of the Participant, an SAR shall be exercisable only by the
Participant or the Participant’s guardian or legal representative. An SAR shall not be subject in any manner to anticipation, alienation, sale, exchange, transfer, assignment, pledge, encumbrance, or garnishment by creditors of the Participant
or the Participant’s beneficiary, except transfer by will or by the laws of descent and distribution. Notwithstanding the foregoing, to the extent permitted by the Committee, in its discretion, and set forth in the Award Agreement evidencing
such Award, a Tandem SAR related to a Nonstatutory Stock Option or a Freestanding SAR shall be assignable or transferable subject to the applicable limitations, if any, described in the General Instructions to
Form S-8 under the Securities Act. 
 8.    RESTRICTED
STOCK AWARDS. 
 Restricted Stock Awards shall be
evidenced by Award Agreements specifying whether the Award is a Restricted Stock Bonus or a Restricted Stock Purchase Right and the number of shares of Stock subject to the Award, in such form as the Committee shall from time to time establish.
Award Agreements evidencing Restricted Stock Awards may incorporate all or any of the terms of the Plan by reference and shall comply with and be subject to the following terms and conditions: 

8.1    Types of Restricted Stock Awards Authorized. Restricted Stock Awards may be granted in the
form of either a Restricted Stock Bonus or a Restricted Stock Purchase Right. Restricted Stock Awards may be granted upon such conditions as the Committee shall determine, including, without limitation, upon the attainment of one or more Performance
Goals described in Section 10.4. If either the grant of or satisfaction of Vesting Conditions applicable to a Restricted Stock Award is to be contingent upon the attainment of one or more Performance Goals, the Committee shall follow procedures
substantially equivalent to those set forth in Sections 10.3 through 10.5(a). 
 8.2    Purchase
Price. The purchase price for shares of Stock issuable under each Restricted Stock Purchase Right shall be established by the Committee in its discretion. No monetary payment (other than applicable tax withholding) shall be required as a
condition of receiving shares of Stock pursuant to a Restricted Stock Bonus, the consideration for which shall be services actually rendered to a Participating Company or for its benefit. Notwithstanding the foregoing, if required by applicable
state corporate law, the Participant shall furnish consideration in the form of cash or past services rendered to a Participating Company or for its benefit having a value not less than the par value of the shares of Stock subject to a Restricted
Stock Award. 

  
 17 

 8.3    Purchase Period. A Restricted Stock Purchase Right
shall be exercisable within a period established by the Committee, which shall in no event exceed thirty (30) days from the effective date of the grant of the Restricted Stock Purchase Right. 

8.4    Payment of Purchase Price. Except as otherwise provided below, payment of the purchase price for the number
of shares of Stock being purchased pursuant to any Restricted Stock Purchase Right shall be made (a) in cash, by check or in cash equivalent, (b) by such other consideration as may be approved by the Committee from time to time to the
extent permitted by applicable law, or (c) by any combination thereof. 
 8.5    Vesting and Restrictions on
Transfer. Shares issued pursuant to any Restricted Stock Award may (but need not) be made subject to Vesting Conditions based upon the satisfaction of such Service requirements, conditions, restrictions or performance criteria, including,
without limitation, Performance Goals as described in Section 10.4, as shall be established by the Committee and set forth in the Award Agreement evidencing such Award. During any period in which shares acquired pursuant to a Restricted Stock
Award remain subject to Vesting Conditions, such shares may not be sold, exchanged, transferred, pledged, assigned or otherwise disposed of other than pursuant to an Ownership Change Event or as provided in Section 8.8. The Committee, in its
discretion, may provide in any Award Agreement evidencing a Restricted Stock Award that, if the satisfaction of Vesting Conditions with respect to any shares subject to such Restricted Stock Award would otherwise occur on a day on which the sale of
such shares would violate the provisions of the Trading Compliance Policy, then satisfaction of the Vesting Conditions automatically shall be determined on the next trading day on which the sale of such shares would not violate the Trading
Compliance Policy. Upon request by the Company, each Participant shall execute any agreement evidencing such transfer restrictions prior to the receipt of shares of Stock hereunder and shall promptly present to the Company any and all certificates
representing shares of Stock acquired hereunder for the placement on such certificates of appropriate legends evidencing any such transfer restrictions. 

8.6    Voting Rights; Dividends and Distributions. Except as provided in this Section, Section 8.5 and any
Award Agreement, during any period in which shares acquired pursuant to a Restricted Stock Award remain subject to Vesting Conditions, the Participant shall have all of the rights of a stockholder of the Company holding shares of Stock, including
the right to vote such shares and to receive all dividends and other distributions paid with respect to such shares; provided, however, that if so determined by the Committee and provided by the Award Agreement, such dividends and distributions
shall be subject to the same Vesting Conditions as the shares subject to the Restricted Stock Award with respect to which such dividends or distributions were paid. In the event of a dividend or distribution paid in shares of Stock or other property
or any other adjustment made upon a change in the capital structure of the Company as described in Section 4.3, any and all new, substituted or additional securities or other property (other than normal cash dividends) to which the Participant
is entitled by reason of the Participant’s Restricted Stock Award shall be immediately subject to the same Vesting Conditions as the shares subject to the Restricted Stock Award with respect to which such dividends or distributions were paid or
adjustments were made. 
 8.7    Effect of Termination of Service. Unless otherwise provided by the
Committee in the Award Agreement evidencing a Restricted Stock Award, if a Participant’s 

  
 18 

 
Service terminates for any reason, whether voluntary or involuntary (including the Participant’s death or disability), then (a) the Company shall have the option to repurchase for the
purchase price paid by the Participant any shares acquired by the Participant pursuant to a Restricted Stock Purchase Right which remain subject to Vesting Conditions as of the date of the Participant’s termination of Service and (b) the
Participant shall forfeit to the Company any shares acquired by the Participant pursuant to a Restricted Stock Bonus which remain subject to Vesting Conditions as of the date of the Participant’s termination of Service. The Company shall have
the right to assign at any time any repurchase right it may have, whether or not such right is then exercisable, to one or more persons as may be selected by the Company. 

8.8    Nontransferability of Restricted Stock Award Rights. Rights to acquire shares of Stock
pursuant to a Restricted Stock Award shall not be subject in any manner to anticipation, alienation, sale, exchange, transfer, assignment, pledge, encumbrance or garnishment by creditors of the Participant or the Participant’s beneficiary,
except transfer by will or the laws of descent and distribution. All rights with respect to a Restricted Stock Award granted to a Participant hereunder shall be exercisable during his or her lifetime only by such Participant or the
Participant’s guardian or legal representative. 
 9.    RESTRICTED STOCK
UNIT AWARDS. 
 Restricted Stock Unit Awards shall be
evidenced by Award Agreements specifying the number of Restricted Stock Units subject to the Award, in such form as the Committee shall from time to time establish. Award Agreements evidencing Restricted Stock Units may incorporate all or any of the
terms of the Plan by reference and shall comply with and be subject to the following terms and conditions: 

9.1    Grant of Restricted Stock Unit Awards. Restricted Stock Unit Awards may be granted upon such conditions as
the Committee shall determine, including, without limitation, upon the attainment of one or more Performance Goals described in Section 10.4. If either the grant of a Restricted Stock Unit Award or the Vesting Conditions with respect to such
Award is to be contingent upon the attainment of one or more Performance Goals, the Committee shall follow procedures substantially equivalent to those set forth in Sections 10.3 through 10.5(a). 

9.2    Purchase Price. No monetary payment (other than applicable tax withholding, if any) shall be required as a
condition of receiving a Restricted Stock Unit Award, the consideration for which shall be services actually rendered to a Participating Company or for its benefit. Notwithstanding the foregoing, if required by applicable state corporate law, the
Participant shall furnish consideration in the form of cash or past services rendered to a Participating Company or for its benefit having a value not less than the par value of the shares of Stock issued upon settlement of the Restricted Stock Unit
Award. 
 9.3    Vesting. Restricted Stock Unit Awards may (but need not) be made subject to Vesting Conditions
based upon the satisfaction of such Service requirements, conditions, restrictions or performance criteria, including, without limitation, Performance Goals as described in Section 10.4, as shall be established by the Committee and set forth in
the Award Agreement evidencing such Award. The Committee, in its discretion, may provide in any 

  
 19 

 
Award Agreement evidencing a Restricted Stock Unit Award that, if the satisfaction of Vesting Conditions with respect to any shares subject to the Award would otherwise occur on a day on which
the sale of such shares would violate the provisions of the Trading Compliance Policy, then the satisfaction of the Vesting Conditions automatically shall be determined on the first to occur of (a) the next trading day on which the sale of such
shares would not violate the Trading Compliance Policy or (b) the later of (i) last day of the calendar year in which the original vesting date occurred or (ii) the last day of the Company’s taxable year in which the original
vesting date occurred. 
 9.4    Voting Rights, Dividend Equivalent Rights and Distributions. Participants shall
have no voting rights with respect to shares of Stock represented by Restricted Stock Units until the date of the issuance of such shares (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of
the Company). However, the Committee, in its discretion, may provide in the Award Agreement evidencing any Restricted Stock Unit Award that the Participant shall be entitled to Dividend Equivalent Rights with respect to the payment of cash dividends
on Stock during the period beginning on the date such Award is granted and ending, with respect to each share subject to the Award, on the earlier of the date the Award is settled or the date on which it is terminated. Such Dividend Equivalent
Rights, if any, shall be paid by crediting the Participant with additional whole Restricted Stock Units as of the date of payment of such cash dividends on Stock. The number of additional Restricted Stock Units (rounded to the nearest whole number)
to be so credited shall be determined by dividing (a) the amount of cash dividends paid on such date with respect to the number of shares of Stock represented by the Restricted Stock Units previously credited to the Participant by (b) the
Fair Market Value per share of Stock on such date. Such additional Restricted Stock Units shall be subject to the same terms and conditions and shall be settled in the same manner and at the same time as the Restricted Stock Units originally subject
to the Restricted Stock Unit Award. In the event of a dividend or distribution paid in shares of Stock or other property or any other adjustment made upon a change in the capital structure of the Company as described in Section 4.3, appropriate
adjustments shall be made in the Participant’s Restricted Stock Unit Award so that it represents the right to receive upon settlement any and all new, substituted or additional securities or other property (other than normal cash dividends) to
which the Participant would be entitled by reason of the shares of Stock issuable upon settlement of the Award, and all such new, substituted or additional securities or other property shall be immediately subject to the same Vesting Conditions as
are applicable to the Award. 
 9.5    Effect of Termination of Service. Unless otherwise provided by the
Committee and set forth in the Award Agreement evidencing a Restricted Stock Unit Award, if a Participant’s Service terminates for any reason, whether voluntary or involuntary (including the Participant’s death or disability), then the
Participant shall forfeit to the Company any Restricted Stock Units pursuant to the Award which remain subject to Vesting Conditions as of the date of the Participant’s termination of Service. 

9.6    Settlement of Restricted Stock Unit Awards. The Company shall issue to a Participant on the date on which
Restricted Stock Units subject to the Participant’s Restricted Stock Unit Award vest or on such other date determined by the Committee, in its discretion, and set forth in the Award Agreement one (1) share of Stock (and/or any other new,
substituted or additional securities or other property pursuant to an adjustment described in

Section 9.4) for each Restricted Stock Unit then becoming vested or otherwise to be settled on such date, subject to the withholding of applicable taxes, if any. If permitted by the
Committee, the Participant may elect, consistent with the requirements of Section 409A, to defer receipt of all or any portion of the shares of Stock or other property otherwise issuable to the Participant pursuant to this Section, and such
deferred issuance date(s) and amount(s) elected by the Participant shall be set forth in the Award Agreement. Notwithstanding the foregoing, the Committee, in its discretion, may provide for settlement of any Restricted Stock Unit Award by payment
to the Participant in cash of an amount equal to the Fair Market Value on the payment date of the shares of Stock or other property otherwise issuable to the Participant pursuant to this Section. 

9.7    Nontransferability of Restricted Stock Unit Awards. The right to receive shares pursuant to a Restricted
Stock Unit Award shall not be subject in any manner to anticipation, alienation, sale, exchange, transfer, assignment, pledge, encumbrance, or garnishment by creditors of the Participant or the Participant’s beneficiary, except transfer by will
or by the laws of descent and distribution. All rights with respect to a Restricted Stock Unit Award granted to a Participant hereunder shall be exercisable during his or her lifetime only by such Participant or the Participant’s guardian or
legal representative. 
 10.    PERFORMANCE
AWARDS. 
 Performance Awards shall be evidenced by Award Agreements in
such form as the Committee shall from time to time establish. Award Agreements evidencing Performance Awards may incorporate all or any of the terms of the Plan by reference and shall comply with and be subject to the following terms and conditions:

 10.1    Types of Performance Awards Authorized. Performance Awards may be granted in the form of either
Performance Shares or Performance Units. Each Award Agreement evidencing a Performance Award shall specify the number of Performance Shares or Performance Units subject thereto, the Performance Award Formula, the Performance Goal(s) and Performance
Period applicable to the Award, and the other terms, conditions and restrictions of the Award. 
 10.2    Initial
Value of Performance Shares and Performance Units. Unless otherwise provided by the Committee in granting a Performance Award, each Performance Share shall have an initial monetary value equal to the Fair Market Value of one (1) share of
Stock, subject to adjustment as provided in Section 4.3, on the effective date of grant of the Performance Share, and each Performance Unit shall have an initial monetary value established by the Committee at the time of grant. The final value
payable to the Participant in settlement of a Performance Award determined on the basis of the applicable Performance Award Formula will depend on the extent to which Performance Goals established by the Committee are attained within the applicable
Performance Period established by the Committee. 
 10.3    Establishment of Performance Period, Performance Goals
and Performance Award Formula. In granting each Performance Award, the Committee shall establish in writing the applicable Performance Period, Performance Award Formula and one or more Performance Goals which, when measured at the end of the
Performance Period, shall 

  
 21 

 
determine on the basis of the Performance Award Formula the final value of the Performance Award to be paid to the Participant. The Committee shall establish the Performance Goal(s) and
Performance Award Formula applicable to each Performance 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 outcome of the Performance Goals remains substantially uncertain. Once established, the Performance Goals and Performance Award Formula applicable to a Covered Employee shall not be changed
during the Performance Period. The Company shall notify each Participant granted a Performance Award of the terms of such Award, including the Performance Period, Performance Goal(s) and Performance Award Formula. 

10.4    Measurement of Performance Goals. Performance Goals shall be established by the Committee on the basis of
targets to be attained (“Performance Targets”) with respect to one or more measures of business or financial performance (each, a “Performance Measure”), subject to the
following: 
 (a)    Performance Measures. Performance Measures shall have the same meanings as used in
the Company’s financial statements, or, if such terms are not used in the Company’s financial statements, they shall have the meaning applied pursuant to generally accepted accounting principles, or as used generally in the Company’s
industry. Performance Measures shall be calculated with respect to the Company and each Subsidiary Corporation consolidated therewith for financial reporting purposes or such division or other business unit as may be selected by the Committee. For
purposes of the Plan, the Performance Measures applicable to a Performance Award shall be calculated in accordance with generally accepted accounting principles, if applicable, but prior to the accrual or payment of any Performance Award for the
same Performance Period and excluding the effect (whether positive or negative) of any change in accounting standards or any extraordinary, unusual or nonrecurring item, as determined by the Committee, occurring after the establishment of the
Performance Goals applicable to the Performance Award. Each such adjustment, if any, shall be made solely for the purpose of providing a consistent basis from period to period for the calculation of Performance Measures in order to prevent the
dilution or enlargement of the Participant’s rights with respect to a Performance Award. Performance Measures may be one or more of the following, as determined by the Committee: 

(i)    revenue; 

(ii)    sales; 

(iii)    expenses; 

(iv)    operating income; 

(v)    gross margin; 

(vi)    operating margin; 

(vii)    earnings before any one or more of: stock-based compensation expense, interest, taxes, depreciation and
amortization; 

  
 22 

 (viii)    pre-tax profit; 

(ix)    net operating income; 

(x)    net income; 

(xi)    economic value added; 

(xii)    free cash flow; 

(xiii)    operating cash flow; 

(xiv)    balance of cash, cash equivalents and marketable securities; 

(xv)    stock price; 

(xvi)    earnings per share; 

(xvii)    return on stockholder equity; 

(xviii)    return on capital; 

(xix)    return on assets; 

(xx)    return on investment; 

(xxi)    employee satisfaction; 

(xxii)    employee retention; 

(xxiii)    market share; 

(xxiv)    customer satisfaction; 

(xxv)    product development; 

(xxvi)    research and development expenses; 

(xxvii)    completion of an identified special project; and 

(xxviii)    completion of a joint venture or other corporate transaction. 

(b)    Performance Targets. Performance Targets may include a minimum, maximum, target level and
intermediate levels of performance, with the final value of a Performance Award determined under the applicable Performance Award Formula by the level attained during the applicable Performance Period. A Performance Target may be stated as an
absolute value or as a value determined relative to an index, budget or other standard selected by the Committee. 

  
 23 

 10.5    Settlement of Performance Awards. 

(a)    Determination of Final Value. As soon as practicable following the completion of the Performance
Period applicable to a Performance Award, the Committee shall certify in writing the extent to which the applicable Performance Goals have been attained and the resulting final value of the Award earned by the Participant and to be paid upon its
settlement in accordance with the applicable Performance Award Formula. 
 (b)    Discretionary Adjustment of
Award Formula. In its discretion, the Committee may, either at the time it grants a Performance Award or at any time thereafter, provide for the positive or negative adjustment of the Performance Award Formula applicable to a Performance
Award granted to any Participant who is not a Covered Employee to reflect such Participant’s individual performance in his or her position with the Company or such other factors as the Committee may determine. If permitted under a Covered
Employee’s Award Agreement, the Committee shall have the discretion, on the basis of such criteria as may be established by the Committee, to reduce some or all of the value of the Performance Award that would otherwise be paid to the Covered
Employee upon its settlement notwithstanding the attainment of any Performance Goal and the resulting value of the Performance Award determined in accordance with the Performance Award Formula. 

(c)    Effect of Leaves of Absence. Unless otherwise required by law or a Participant’s Award
Agreement, payment of the final value, if any, of a Performance Award held by a Participant who has taken in excess of thirty (30) days in unpaid leaves of absence during a Performance Period shall be prorated on the basis of the number of days
of the Participant’s Service during the Performance Period during which the Participant was not on an unpaid leave of absence. 

(d)    Notice to Participants. As soon as practicable following the Committee’s determination and
certification in accordance with Sections 10.5(a) and (b), the Company shall notify each Participant of the determination of the Committee. 

(e)    Payment in Settlement of Performance Awards. As soon as practicable following the Committee’s
determination and certification in accordance with Sections 10.5(a) and (b), but in any event within the Short-Term Deferral Period described in Section 15.1 (except as otherwise provided below or consistent with the requirements of
Section 409A), payment shall be made to each eligible Participant (or such Participant’s legal representative or other person who acquired the right to receive such payment by reason of the Participant’s death) of the final value of
the Participant’s Performance Award. Payment of such amount shall be made in cash, shares of Stock, or a combination thereof as determined by the Committee. Unless otherwise provided in the Award Agreement evidencing a Performance Award,
payment shall be made in a lump sum. If permitted by the Committee, the Participant may elect, consistent with the requirements of Section 409A, to defer receipt of all or any portion of the payment to be made to Participant pursuant to this
Section, and such deferred payment date(s) elected by the Participant shall be set forth in the Award Agreement. If any payment is to be made on a deferred basis, the Committee may, but shall not be obligated to, provide for the payment during the
deferral period of Dividend Equivalent Rights or interest. 

  
 24 

 (f)    Provisions Applicable to Payment in Shares. If
payment is to be made in shares of Stock, the number of such shares shall be determined by dividing the final value of the Performance Award by the Fair Market Value of a share of Stock determined by the method specified in the Award Agreement.
Shares of Stock issued in payment of any Performance Award may be fully vested and freely transferable shares or may be shares of Stock subject to Vesting Conditions as provided in Section 8.5. Any shares subject to Vesting Conditions shall be
evidenced by an appropriate Award Agreement and shall be subject to the provisions of Sections 8.5 through 8.8 above. 

10.6    Voting Rights; Dividend Equivalent Rights and Distributions. Participants shall have no voting rights with
respect to shares of Stock represented by Performance Share Awards until the date of the issuance of such shares, if any (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company).
However, the Committee, in its discretion, may provide in the Award Agreement evidencing any Performance Share Award that the Participant shall be entitled to Dividend Equivalent Rights with respect to the payment of cash dividends on Stock during
the period beginning on the date the Award is granted and ending, with respect to each share subject to the Award, on the earlier of the date on which the Performance Shares are settled or the date on which they are forfeited. Such Dividend
Equivalent Rights, if any, shall be credited to the Participant in the form of additional whole Performance Shares as of the date of payment of such cash dividends on Stock. The number of additional Performance Shares (rounded to the nearest whole
number) to be so credited shall be determined by dividing (a) the amount of cash dividends paid on the dividend payment date with respect to the number of shares of Stock represented by the Performance Shares previously credited to the
Participant by (b) the Fair Market Value per share of Stock on such date. Dividend Equivalent Rights may be paid currently or may be accumulated and paid to the extent that Performance Shares become nonforfeitable, as determined by the
Committee. Settlement of Dividend Equivalent Rights may be made in cash, shares of Stock, or a combination thereof as determined by the Committee, and may be paid on the same basis as settlement of the related Performance Share as provided in
Section 10.5. Dividend Equivalent Rights shall not be paid with respect to Performance Units. In the event of a dividend or distribution paid in shares of Stock or other property or any other adjustment made upon a change in the capital
structure of the Company as described in Section 4.3, appropriate adjustments shall be made in the Participant’s Performance Share Award so that it represents the right to receive upon settlement any and all new, substituted or additional
securities or other property (other than normal cash dividends) to which the Participant would be entitled by reason of the shares of Stock issuable upon settlement of the Performance Share Award, and all such new, substituted or additional
securities or other property shall be immediately subject to the same Performance Goals as are applicable to the Award. 

10.7    Effect of Termination of Service. Unless otherwise provided by the Committee and set forth in the Award
Agreement evidencing a Performance Award, the effect of a Participant’s termination of Service on the Performance Award shall be as follows: 

(a)    Death or Disability. If the Participant’s Service terminates because of the death or Disability
of the Participant before the completion of the Performance Period applicable to the Performance Award, the final value of the Participant’s Performance Award shall be determined by the extent to which the applicable Performance Goals have been

  
 25 

 
attained with respect to the entire Performance Period and shall be prorated based on the number of months of the Participant’s Service during the Performance Period. Payment shall be made
following the end of the Performance Period in any manner permitted by Section 10.5. 
 (b)    Other
Termination of Service. If the Participant’s Service terminates for any reason except death or Disability before the completion of the Performance Period applicable to the Performance Award, such Award shall be forfeited in its
entirety; provided, however, that in the event of an involuntary termination of the Participant’s Service, the Committee, in its discretion, may waive the automatic forfeiture of all or any portion of any such Award and determine the final
value of the Performance Award in the manner provided by Section 10.7(a). Payment of any amount pursuant to this Section shall be made following the end of the Performance Period in any manner permitted by Section 10.5. 

10.8    Nontransferability of Performance Awards. Prior to settlement in accordance with the provisions of the
Plan, no Performance Award shall be subject in any manner to anticipation, alienation, sale, exchange, transfer, assignment, pledge, encumbrance, or garnishment by creditors of the Participant or the Participant’s beneficiary, except transfer
by will or by the laws of descent and distribution. All rights with respect to a Performance Award granted to a Participant hereunder shall be exercisable during his or her lifetime only by such Participant or the Participant’s guardian or
legal representative. 
 11.    CASH-BASED AWARDS AND
OTHER STOCK-BASED AWARDS. 

Cash-Based Awards and Other Stock-Based Awards shall be evidenced by Award Agreements in such form as the Committee shall from time to time
establish. Award Agreements evidencing Cash-Based Awards and Other Stock-Based Awards may incorporate all or any of the terms of the Plan by reference and shall comply with and be subject to the following terms and conditions: 

11.1    Grant of Cash-Based Awards. Subject to the provisions of the Plan, the Committee, at any time and from time
to time, may grant Cash-Based Awards to Participants in such amounts and upon such terms and conditions, including the achievement of performance criteria, as the Committee may determine. 

11.2    Grant of Other Stock-Based Awards. The Committee may grant other types of equity-based or equity-related
Awards not otherwise described by the terms of this Plan (including the grant or offer for sale of unrestricted securities, stock-equivalent units, stock appreciation units, securities or debentures convertible into common stock or other forms
determined by the Committee) in such amounts and subject to such terms and conditions as the Committee shall determine. Such Awards may involve the transfer of actual shares of Stock to Participants, or payment in cash or otherwise of amounts based
on the value of Stock and may include, without limitation, Awards designed to comply with or take advantage of the applicable local laws of jurisdictions other than the United States. 

11.3    Value of Cash-Based and Other Stock-Based Awards. Each Cash-Based Award shall specify a monetary payment
amount or payment range as determined by the Committee. Each Other Stock-Based Award shall be expressed in terms of shares of Stock or 

  
 26 

 
units based on such shares of Stock, as determined by the Committee. The Committee may require the satisfaction of such Service requirements, conditions, restrictions or performance criteria,
including, without limitation, Performance Goals as described in Section 10.4, as shall be established by the Committee and set forth in the Award Agreement evidencing such Award. If the Committee exercises its discretion to establish
performance criteria, the final value of Cash-Based Awards or Other Stock-Based Awards that will be paid to the Participant will depend on the extent to which the performance criteria are met. 

11.4    Payment or Settlement of Cash-Based Awards and Other Stock-Based Awards. Payment or settlement, if any,
with respect to a Cash-Based Award or an Other Stock-Based Award shall be made in accordance with the terms of the Award, in cash, shares of Stock or other securities or any combination thereof as the Committee determines. To the extent applicable,
payment or settlement with respect to each Cash-Based Award and Other Stock-Based Award shall be made in compliance with the requirements of Section 409A. 

11.5    Voting Rights; Dividend Equivalent Rights and Distributions. Participants shall have no voting rights with
respect to shares of Stock represented by Other Stock-Based Awards until the date of the issuance of such shares of Stock (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), if
any, in settlement of such Award. However, the Committee, in its discretion, may provide in the Award Agreement evidencing any Other Stock-Based Award that the Participant shall be entitled to Dividend Equivalent Rights with respect to the payment
of cash dividends on Stock during the period beginning on the date such Award is granted and ending, with respect to each share subject to the Award, on the earlier of the date the Award is settled or the date on which it is terminated. Such
Dividend Equivalent Rights, if any, shall be paid in accordance with the provisions set forth in Section 9.4. Dividend Equivalent Rights shall not be granted with respect to Cash-Based Awards. In the event of a dividend or distribution paid in
shares of Stock or other property or any other adjustment made upon a change in the capital structure of the Company as described in Section 4.3, appropriate adjustments shall be made in the Participant’s Other Stock-Based Award so that it
represents the right to receive upon settlement any and all new, substituted or additional securities or other property (other than normal cash dividends) to which the Participant would be entitled by reason of the shares of Stock issuable upon
settlement of such Award, and all such new, substituted or additional securities or other property shall be immediately subject to the same Vesting Conditions and performance criteria, if any, as are applicable to the Award. 

11.6    Effect of Termination of Service. Each Award Agreement evidencing a Cash-Based Award or Other Stock-Based
Award shall set forth the extent to which the Participant shall have the right to retain such Award following termination of the Participant’s Service. Such provisions shall be determined in the discretion of the Committee, need not be uniform
among all Cash-Based Awards or Other Stock-Based Awards, and may reflect distinctions based on the reasons for termination, subject to the requirements of Section 409A, if applicable. 

11.7    Nontransferability of Cash-Based Awards and Other Stock-Based Awards. Prior to the payment or settlement of
a Cash-Based Award or Other Stock-Based Award, the Award shall not be subject in any manner to anticipation, alienation, sale, exchange, 

  
 27 

 
transfer, assignment, pledge, encumbrance, or garnishment by creditors of the Participant or the Participant’s beneficiary, except transfer by will or by the laws of descent and
distribution. The Committee may impose such additional restrictions on any shares of Stock issued in settlement of Cash-Based Awards and Other Stock-Based Awards as it may deem advisable, including, without limitation, minimum holding period
requirements, restrictions under applicable federal securities laws, under the requirements of any stock exchange or market upon which such shares of Stock are then listed and/or traded, or under any state securities laws or foreign law applicable
to such shares of Stock. 
 12.    STANDARD FORMS OF
AWARD AGREEMENT. 
 12.1    Award
Agreements. Each Award shall comply with and be subject to the terms and conditions set forth in the appropriate form of Award Agreement approved by the Committee and as amended from time to time. No Award or purported Award shall
be a valid and binding obligation of the Company unless evidenced by a fully executed Award Agreement, which execution may be evidenced by electronic means. Any Award Agreement may consist of an appropriate form of Notice of Grant and a form of
Agreement incorporated therein by reference, or such other form or forms, including electronic media, as the Committee may approve from time to time. 

12.2    Authority to Vary Terms. The Committee shall have the authority from time to time to vary the
terms of any standard form of Award Agreement either in connection with the grant or amendment of an individual Award or in connection with the authorization of a new standard form or forms; provided, however, that the terms and conditions of any
such new, revised or amended standard form or forms of Award Agreement are not inconsistent with the terms of the Plan. 

13.    CHANGE IN
CONTROL. 
 13.1    Effect of Change in Control on
Awards. Subject to the requirements and limitations of Section 409A, if applicable, the Committee may provide for any one or more of the following: 

(a)    Accelerated Vesting. In its discretion, the Committee may provide in the grant of any Award or at
any other time may take such action as it deems appropriate to provide for acceleration of the exercisability, vesting and/or settlement in connection with a Change in Control of each or any outstanding Award or portion thereof and shares acquired
pursuant thereto upon such conditions, including termination of the Participant’s Service prior to, upon, or following such Change in Control, and to such extent as the Committee shall determine. 

(b)    Assumption, Continuation or Substitution. In the event of a Change in Control, the surviving,
continuing, successor, or purchasing corporation or other business entity or parent thereof, as the case may be (the “Acquiror”), may, without the consent of any Participant, either assume or continue the
Company’s rights and obligations under each or any Award or portion thereof outstanding immediately prior to the Change in Control or substitute for each or any such outstanding Award or portion thereof a substantially equivalent award with
respect to the Acquiror’s stock, as applicable. For purposes of this Section, if so 

  
 28 

 
determined by the Committee in its discretion, an Award denominated in shares of Stock shall be deemed assumed if, following the Change in Control, the Award confers the right to receive, subject
to the terms and conditions of the Plan and the applicable Award Agreement, for each share of Stock subject to the Award immediately prior to the Change in Control, the consideration (whether stock, cash, other securities or property or a
combination thereof) to which a holder of a share of Stock on the effective date of the Change in Control was entitled; provided, however, that if such consideration is not solely common stock of the Acquiror, the Committee may, with the consent of
the Acquiror, provide for the consideration to be received upon the exercise or settlement of the Award, for each share of Stock subject to the Award, to consist solely of common stock of the Acquiror equal in Fair Market Value to the per share
consideration received by holders of Stock pursuant to the Change in Control. Any Award or portion thereof which is neither assumed or continued by the Acquiror in connection with the Change in Control nor exercised or settled as of the time of
consummation of the Change in Control shall terminate and cease to be outstanding effective as of the time of consummation of the Change in Control. 

(c)    Cash-Out of Outstanding Stock-Based Awards. The Committee
may, in its discretion and without the consent of any Participant, determine that, upon the occurrence of a Change in Control, each or any Award denominated in shares of Stock or portion thereof outstanding immediately prior to the Change in Control
and not previously exercised or settled shall be canceled in exchange for a payment with respect to each vested share (and each unvested share, if so determined by the Committee) of Stock subject to such canceled Award in (i) cash,
(ii) stock of the Company or of a corporation or other business entity a party to the Change in Control, or (iii) other property which, in any such case, shall be in an amount having a Fair Market Value equal to the Fair Market Value of
the consideration to be paid per share of Stock in the Change in Control, reduced (but not below zero) by the exercise or purchase price per share, if any, under such Award. In the event such determination is made by the Committee, an Award having
an exercise or purchase price per share equal to or greater than the Fair Market Value of the consideration to be paid per share of Stock in the Change in Control may be canceled without payment of consideration to the holder thereof. Payment
pursuant to this Section (reduced by applicable withholding taxes, if any) shall be made to Participants in respect of the vested portions of their canceled Awards as soon as practicable following the date of the Change in Control and in respect of
the unvested portions of their canceled Awards in accordance with the vesting schedules applicable to such Awards. 

13.2    Effect of Change in Control on Nonemployee Director Awards. Subject to the requirements and limitations of
Section 409A, if applicable, including as provided by Section 15.4(e), in the event of a Change in Control, each outstanding Nonemployee Director Award shall become immediately exercisable and vested in full and, except to the extent
assumed, continued or substituted for pursuant to Section 13.1(b), shall be settled effective immediately prior to the time of consummation of the Change in Control. 

13.3    Federal Excise Tax Under Section 4999 of the Code. 

(a)    Excess Parachute Payment. In the event that any acceleration of vesting pursuant to an Award and any
other payment or benefit received or to be received by a Participant would subject the Participant to any excise tax pursuant to Section 4999 of the Code 

  
 29 

 
due to the characterization of such acceleration of vesting, payment or benefit as an “excess parachute payment” under Section 280G of the Code, the Participant may elect to reduce
the amount of any acceleration of vesting called for under the Award in order to avoid such characterization. 

(b)    Determination by Independent Accountants. To aid the Participant in making any election called for
under Section 13.3(a), no later than the date of the occurrence of any event that might reasonably be anticipated to result in an “excess parachute payment” to the Participant as described in Section 13.3(a), the Company shall
request a determination in writing by independent public accountants selected by the Company (the “Accountants”). As soon as practicable thereafter, the Accountants shall determine and report to the Company and
the Participant the amount of such acceleration of vesting, payments and benefits which would produce the greatest after-tax benefit to the Participant. For the purposes of such determination, the Accountants
may rely on reasonable, good faith interpretations concerning the application of Sections 280G and 4999 of the Code. The Company and the Participant shall furnish to the Accountants such information and documents as the Accountants may reasonably
request in order to make their required determination. The Company shall bear all fees and expenses the Accountants charge in connection with their services contemplated by this Section. 

14.    COMPLIANCE WITH SECURITIES
LAW. 
 The grant of Awards and the issuance of shares of Stock pursuant
to any Award shall be subject to compliance with all applicable requirements of federal, state and foreign law with respect to such securities and the requirements of any stock exchange or market system upon which the Stock may then be listed. In
addition, no Award may be exercised or shares issued pursuant to an Award unless (a) a registration statement under the Securities Act shall at the time of such exercise or issuance be in effect with respect to the shares issuable pursuant to
the Award, or (b) in the opinion of legal counsel to the Company, the shares issuable pursuant to the Award may be issued in accordance with the terms of an applicable exemption from the registration requirements of the Securities Act. The
inability of the Company to obtain from any regulatory body having jurisdiction the authority, if any, deemed by the Company’s legal counsel to be necessary to the lawful issuance and sale of any shares hereunder shall relieve the Company of
any liability in respect of the failure to issue or sell such shares as to which such requisite authority shall not have been obtained. As a condition to issuance of any Stock, the Company may require the Participant to satisfy any qualifications
that may be necessary or appropriate, to evidence compliance with any applicable law or regulation and to make any representation or warranty with respect thereto as may be requested by the Company. 

  
 30 

 15.    COMPLIANCE WITH
SECTION 409A. 

15.1    Awards Subject to Section 409A. The Company intends that Awards granted pursuant to the
Plan shall either be exempt from or comply with Section 409A, and the Plan shall be so construed. The provisions of this Section 15 shall apply to any Award or portion thereof that constitutes or provides for payment of Section 409A
Deferred Compensation. Such Awards may include, without limitation: 
 (a)    A Nonstatutory Stock Option or SAR that
includes any feature for the deferral of compensation other than the deferral of recognition of income until the later of (i) the exercise or disposition of the Award or (ii) the time the stock acquired pursuant to the exercise of the
Award first becomes substantially vested. 
 (b)    Any Restricted Stock Unit Award, Performance Award, Cash-Based
Award or Other Stock-Based Award that either (i) provides by its terms for settlement of all or any portion of the Award at a time or upon an event that will or may occur later than the end of the Short-Term Deferral Period (as defined below)
or (ii) permits the Participant granted the Award to elect one or more dates or events upon which the Award will be settled after the end of the Short-Term Deferral Period. 

Subject to the provisions of Section 409A, the term “Short-Term Deferral Period” means the 21⁄2 month period ending on the later of (i) the 15th day of the third month following the end of the Participant’s taxable year in which the right to payment
under the applicable portion of the Award is no longer subject to a substantial risk of forfeiture or (ii) the 15th day of the third month following the end of the Company’s taxable year in which the right to payment under the applicable
portion of the Award is no longer subject to a substantial risk of forfeiture. For this purpose, the term “substantial risk of forfeiture” shall have the meaning provided by Section 409A. 

15.2    Deferral and/or Distribution Elections. Except as otherwise permitted or required by Section 409A, the
following rules shall apply to any compensation deferral and/or payment elections (each, an “Election”) that may be permitted or required by the Committee pursuant to an Award providing Section 409A Deferred
Compensation: 
 (a)    Elections must be in writing and specify the amount of the payment in settlement of an Award
being deferred, as well as the time and form of payment as permitted by this Plan. 
 (b)    Elections shall be made by
the end of the Participant’s taxable year prior to the year in which services commence for which an Award may be granted to such Participant. 

(c)    Elections shall continue in effect until a written revocation or change in Election is received by the Company,
except that a written revocation or change in Election must be received by the Company prior to the last day for making the Election determined in accordance with paragraph (b) above or as permitted by Section 15.3. 

15.3    Subsequent Elections. Except as otherwise permitted or required by Section 409A, any
Award providing Section 409A Deferred Compensation which permits a subsequent Election to delay the payment or change the form of payment in settlement of such Award shall comply with the following requirements: 

(a)    No subsequent Election may take effect until at least twelve (12) months after the date on which the
subsequent Election is made. 

  
 31 

 (b)    Each subsequent Election related to a payment in settlement of
an Award not described in Section 15.4(a)(ii), 15.4(a)(iii) or 15.4(a)(vi) must result in a delay of the payment for a period of not less than five (5) years from the date on which such payment would otherwise have been made. 

(c)    No subsequent Election related to a payment pursuant to Section 15.4(a)(iv) shall be made less than twelve
(12) months before the date on which such payment would otherwise have been made. 
 (d)    Subsequent Elections
shall continue in effect until a written revocation or change in the subsequent Election is received by the Company, except that a written revocation or change in a subsequent Election must be received by the Company prior to the last day for making
the subsequent Election determined in accordance the preceding paragraphs of this Section 15.3. 

15.4    Payment of Section 409A Deferred Compensation. 

(a)    Permissible Payments. Except as otherwise permitted or required by Section 409A, an Award
providing Section 409A Deferred Compensation must provide for payment in settlement of the Award only upon one or more of the following: 

(i)    The Participant’s “separation from service” (as such term is defined by Section 409A); 

(ii)    The Participant’s becoming “disabled” (as such term is defined by Section 409A); 

(iii)    The Participant’s death; 

(iv)    A time or fixed schedule that is either (i) specified by the Committee upon the grant of an Award and set
forth in the Award Agreement evidencing such Award or (ii) specified by the Participant in an Election complying with the requirements of Section 15.2 or 15.3, as applicable; 

(v)    A change in the ownership or effective control or the Company or in the ownership of a substantial portion of the
assets of the Company determined in accordance with Section 409A; or 
 (vi)    The occurrence of an
“unforeseeable emergency” (as such term is defined by Section 409A). 
 (b)    Required Delay in
Payment to Specified Employee Pursuant to Separation from Service. Notwithstanding any provision of the Plan or an Award Agreement to the contrary, except as otherwise permitted by Section 409A, no payment pursuant to
Section 15.4(a)(i) in settlement of an Award providing for Section 409A Deferred Compensation may be made to a Participant who is a “specified employee” (as such term is defined by Section 409A) as of the date of the
Participant’s separation from service before the date (the “Delayed Payment Date”) that is six (6) months after the date of such Participant’s separation from service, or, if earlier, the date of
the Participant’s death. All such amounts that would, but for this paragraph, become payable prior to the Delayed Payment Date shall be accumulated and paid on the Delayed Payment Date. 

  
 32 

 (c)    Payment Upon Disability. All distributions payable
by reason of a Participant becoming disabled shall be paid in a lump sum or in periodic installments as established by the Participant’s Election. If the Participant has made no Election with respect to distributions upon becoming disabled, all
such distributions shall be paid in a lump sum upon the determination that the Participant has become disabled. 

(d)    Payment Upon Death. If a Participant dies before complete distribution of amounts payable
upon settlement of an Award subject to Section 409A, such undistributed amounts shall be distributed to his or her beneficiary under the distribution method for death established by the Participant’s Election upon receipt by the Committee
of satisfactory notice and confirmation of the Participant’s death. If the Participant has made no Election with respect to distributions upon death, all such distributions shall be paid in a lump sum upon receipt by the Committee of
satisfactory notice and confirmation of the Participant’s death. 
 (e)    Payment Upon Change in
Control. Notwithstanding any provision of the Plan or an Award Agreement to the contrary, to the extent that any amount constituting Section 409A Deferred Compensation would become payable under this Plan by reason of a Change in
Control, such amount shall become payable only if the event constituting a Change in Control would also constitute a change in ownership or effective control of the Company or a change in the ownership of a substantial portion of the assets of the
Company within the meaning of Section 409A. Any Award which constitutes Section 409A Deferred Compensation and which would vest and otherwise become payable upon a Change in Control as a result of the failure of the Acquiror to assume,
continue or substitute for such Award in accordance with Section 13.1(b) shall vest to the extent provided by such Award but shall be converted automatically at the effective time of such Change in Control into a right to receive, in cash on
the date or dates such award would have been settled in accordance with its then existing settlement schedule (or as required by Section 15.4(b)), an amount or amounts equal in the aggregate to the intrinsic value of the Award at the time of
the Change in Control. 
 (f)    Payment Upon Unforeseeable Emergency. The Committee shall have the
authority to provide in the Award Agreement evidencing any Award providing for Section 409A Deferred Compensation for payment in settlement of all or a portion of such Award in the event that a Participant establishes, to the satisfaction of
the Committee, the occurrence of an unforeseeable emergency. In such event, the amount(s) distributed with respect to such unforeseeable emergency cannot exceed the amounts reasonably necessary to satisfy the emergency need plus amounts necessary to
pay taxes reasonably anticipated as a result of such distribution(s), after taking into account the extent to which such emergency need is or may be relieved through reimbursement or compensation by insurance or otherwise, by liquidation of the
Participant’s assets (to the extent the liquidation of such assets would not itself cause severe financial hardship) or by cessation of deferrals under the Award. All distributions with respect to an unforeseeable emergency shall be made in a
lump sum as soon as practicable following the Committee’s determination that an unforeseeable emergency has occurred. The Committee’s decision with respect to whether an unforeseeable emergency has occurred and the manner in which, if at
all, the payment in settlement of an Award shall be altered or modified, shall be final, conclusive, and not subject to approval or appeal. 

  
 33 

 (g)    Prohibition of Acceleration of Payments.
Notwithstanding any provision of the Plan or an Award Agreement to the contrary, this Plan does not permit the acceleration of the time or schedule of any payment under an Award providing Section 409A Deferred Compensation, except as
permitted by Section 409A. 
 16.    TAX
WITHHOLDING. 
 16.1    Tax Withholding in
General. The Company shall have the right to deduct from any and all payments made under the Plan, or to require the Participant, through payroll withholding, cash payment or otherwise, to make adequate provision for, the federal, state, local
and foreign taxes (including social insurance), if any, required by law to be withheld by any Participating Company with respect to an Award or the shares acquired pursuant thereto. The Company shall have no obligation to deliver shares of Stock, to
release shares of Stock from an escrow established pursuant to an Award Agreement, or to make any payment in cash under the Plan until the Participating Company Group’s tax withholding obligations have been satisfied by the Participant. 

16.2    Withholding in Shares. The Company shall have the right, but not the obligation, to deduct from the shares
of Stock issuable to a Participant upon the exercise or settlement of an Award, or to accept from the Participant the tender of, a number of whole shares of Stock having a Fair Market Value, as determined by the Company, equal to all or any part of
the tax withholding obligations of any Participating Company. The Fair Market Value of any shares of Stock withheld or tendered to satisfy any such tax withholding obligations shall not exceed the amount determined by the applicable minimum
statutory withholding rates. 
 17.    AMENDMENT,
SUSPENSION OR TERMINATION OF PLAN. 

The Committee may amend, suspend or terminate the Plan at any time. However, without the approval of the Company’s stockholders, there
shall be (a) no increase in the maximum aggregate number of shares of Stock that may be issued under the Plan (except by operation of the provisions of Section 4.3), (b) no change in the class of persons eligible to receive Incentive
Stock Options, and (c) no other amendment of the Plan that would require approval of the Company’s stockholders under any applicable law, regulation or rule, including the rules of any stock exchange or quotation system upon which the
Stock may then be listed or quoted. No amendment, suspension or termination of the Plan shall affect any then outstanding Award unless expressly provided by the Committee. Except as provided by the next sentence, no amendment, suspension or
termination of the Plan may adversely affect any then outstanding Award without the consent of the Participant. Notwithstanding any other provision of the Plan to the contrary, the Committee may, in its sole and absolute discretion and without the
consent of any Participant, amend the Plan or any Award Agreement, to take effect retroactively or otherwise, as it deems necessary or advisable for the purpose of conforming the Plan or such Award Agreement to any present or future law, regulation
or rule applicable to the Plan, including, but not limited to, Section 409A. 

  
 34 

 18.    MISCELLANEOUS
PROVISIONS. 
 18.1    Repurchase
Rights. Shares issued under the Plan may be subject to one or more repurchase options, or other conditions and restrictions as determined by the Committee in its discretion at the time the Award is granted. The Company shall have
the right to assign at any time any repurchase right it may have, whether or not such right is then exercisable, to one or more persons as may be selected by the Company. Upon request by the Company, each Participant shall execute any agreement
evidencing such transfer restrictions prior to the receipt of shares of Stock hereunder and shall promptly present to the Company any and all certificates representing shares of Stock acquired hereunder for the placement on such certificates of
appropriate legends evidencing any such transfer restrictions. 
 18.2    Forfeiture Events. 

(a)    The Committee may specify in an Award Agreement that the Participant’s rights, payments, and benefits with
respect to an Award shall be subject to reduction, cancellation, forfeiture, or recoupment upon the occurrence of specified events, in addition to any otherwise applicable vesting or performance conditions of an Award. Such events may include, but
shall not be limited to, termination of Service for Cause or any act by a Participant, whether before or after termination of Service, that would constitute Cause for termination of Service. 

(b)    If the Company is required to prepare an accounting restatement due to the material noncompliance of the Company,
as a result of misconduct, with any financial reporting requirement under the securities laws, any Participant who knowingly or through gross negligence engaged in the misconduct, or who knowingly or through gross negligence failed to prevent the
misconduct, and any Participant who is one of the individuals subject to automatic forfeiture under Section 304 of the Sarbanes-Oxley Act of 2002, shall reimburse the Company for (i) the amount of any payment in settlement of an Award
received by such Participant during the twelve- (12-) month period following the first public issuance or filing with the United States Securities and Exchange Commission (whichever first occurred) of the
financial document embodying such financial reporting requirement, and (ii) any profits realized by such Participant from the sale of securities of the Company during such twelve- (12-) month period. 

18.3    Provision of Information. Each Participant shall be given access to information concerning the Company
equivalent to that information generally made available to the Company’s common stockholders. 
 18.4    Rights
as Employee, Consultant or Director. No person, even though eligible pursuant to Section 5, shall have a right to be selected as a Participant, or, having been so selected, to be selected again as a Participant. Nothing in the Plan or any
Award granted under the Plan shall confer on any Participant a right to remain an Employee, Consultant or Director or interfere with or limit in any way any right of a Participating Company to terminate the Participant’s Service at any time. To
the extent that an Employee of a Participating Company other than the Company receives an Award under the Plan, that Award shall in no event be understood or interpreted to mean that the Company is the Employee’s employer or that the Employee
has an employment relationship with the Company. 

  
 35 

 18.5    Rights as a Stockholder. A Participant shall have no
rights as a stockholder with respect to any shares covered by an Award until the date of the issuance of such shares (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company). No
adjustment shall be made for dividends, distributions or other rights for which the record date is prior to the date such shares are issued, except as provided in Section 4.3 or another provision of the Plan. 

18.6    Delivery of Title to Shares. Subject to any governing rules or regulations, the Company shall issue or
cause to be issued the shares of Stock acquired pursuant to an Award and shall deliver such shares to or for the benefit of the Participant by means of one or more of the following: (a) by delivering to the Participant evidence of book entry
shares of Stock credited to the account of the Participant, (b) by depositing such shares of Stock for the benefit of the Participant with any broker with which the Participant has an account relationship, or (c) by delivering such shares
of Stock to the Participant in certificate form. 
 18.7    Fractional Shares. The Company shall not be required
to issue fractional shares upon the exercise or settlement of any Award. 
 18.8    Retirement and Welfare Plans.
Neither Awards made under this Plan nor shares of Stock or cash paid pursuant to such Awards may be included as “compensation” for purposes of computing the benefits payable to any Participant under any Participating Company’s
retirement plans (both qualified and non-qualified) or welfare benefit plans unless such other plan expressly provides that such compensation shall be taken into account in computing a Participant’s
benefit. 
 18.9    Beneficiary Designation. Subject to local laws and procedures, each Participant may file with
the Company a written designation of a beneficiary who is to receive any benefit under the Plan to which the Participant is entitled in the event of such Participant’s death before he or she receives any or all of such benefit. Each designation
will revoke all prior designations by the same Participant, shall be in a form prescribed by the Company, and will be effective only when filed by the Participant in writing with the Company during the Participant’s lifetime. If a married
Participant designates a beneficiary other than the Participant’s spouse, the effectiveness of such designation may be subject to the consent of the Participant’s spouse. If a Participant dies without an effective designation of a
beneficiary who is living at the time of the Participant’s death, the Company will pay any remaining unpaid benefits to the Participant’s legal representative. 

18.10    Severability. If any one or more of the provisions (or any part thereof) of this Plan shall be held
invalid, illegal or unenforceable in any respect, such provision shall be modified so as to make it valid, legal and enforceable, and the validity, legality and enforceability of the remaining provisions (or any part thereof) of the Plan shall not
in any way be affected or impaired thereby. 
 18.11    No Constraint on Corporate Action. Nothing in this Plan
shall be construed to: (a) limit, impair, or otherwise affect the Company’s or another Participating Company’s right or power to make adjustments, reclassifications, reorganizations, or changes of its capital or business structure, or
to merge or consolidate, or dissolve, liquidate, sell, or transfer all or any part of its business or assets; or (b) limit the right or power of the Company or another Participating Company to take any action which such entity deems to be
necessary or appropriate. 

  
 36 

 18.12    Unfunded Obligation. Participants shall have the status
of general unsecured creditors of the Company. Any amounts payable to Participants pursuant to the Plan shall be considered unfunded and unsecured obligations for all purposes, including, without limitation, Title I of the Employee Retirement
Income Security Act of 1974. No Participating Company shall be required to segregate any monies from its general funds, or to create any trusts, or establish any special accounts with respect to such obligations. The Company shall retain at all
times beneficial ownership of any investments, including trust investments, which the Company may make to fulfill its payment obligations hereunder. Any investments or the creation or maintenance of any trust or any Participant account shall not
create or constitute a trust or fiduciary relationship between the Committee or any Participating Company and a Participant, or otherwise create any vested or beneficial interest in any Participant or the Participant’s creditors in any assets
of any Participating Company. The Participants shall have no claim against any Participating Company for any changes in the value of any assets which may be invested or reinvested by the Company with respect to the Plan. 

18.13    Choice of Law. Except to the extent governed by applicable federal law, the validity, interpretation,
construction and performance of the Plan and each Award Agreement shall be governed by the laws of the State of Washington, without regard to its conflict of law rules. 

IN WITNESS WHEREOF, the undersigned Secretary of the Company certifies that the foregoing sets forth the Adaptive Biotechnologies Corporation
2009 Equity Incentive Plan as duly adopted by the Board on December 17, 2009.

 ADAPTIVE BIOTECHNOLOGIES CORPORATION 

STOCK OPTION AGREEMENT 

Adaptive Biotechnologies Corporation, formerly known as Adaptive TCR Corporation, has granted to the Participant named in the Notice of Grant
of Stock Option (the “Grant Notice”) to which this Stock Option Agreement (the “Option Agreement”) is attached an option (the “Option”) to purchase certain shares of Stock upon the terms and
conditions set forth in the Grant Notice and this Option Agreement. The Option has been granted pursuant to and shall in all respects be subject to the terms and conditions of the Adaptive Biotechnologies Corporation 2009 Equity Incentive Plan (the
“Plan”), as amended to the Date of Grant, the provisions of which are incorporated herein by reference. By signing the Grant Notice, the Participant: (a) acknowledges receipt of, and represents that the Participant has read and
is familiar with, the Grant Notice, this Option Agreement and the Plan, (b) accepts the Option subject to all of the terms and conditions of the Grant Notice, this Option Agreement and the Plan, and (c) agrees to accept as binding,
conclusive and final all decisions or interpretations of the Board upon any questions arising under the Grant Notice, this Option Agreement or the Plan. 

1.    DEFINITIONS AND
CONSTRUCTION. 
 1.1    Definitions. Unless
otherwise defined herein, capitalized terms shall have the meanings assigned to such terms in the Grant Notice or the Plan. 

1.2    Construction. Captions and titles contained herein are for convenience only and shall not affect the meaning
or interpretation of any provision of this Option Agreement. Except when otherwise indicated by the context, the singular shall include the plural and the plural shall include the singular. Use of the term “or” is not intended to be
exclusive, unless the context clearly requires otherwise. 
 2.    TAX
CONSEQUENCES. 
 2.1    Tax Status of Option.
This Option is intended to have the tax status designated in the Grant Notice. 
 (a)    Incentive Stock Option.
If the Grant Notice so designates, this Option is intended to be an Incentive Stock Option within the meaning of Section 422(b) of the Code, but the Company does not represent or warrant that this Option qualifies as such. The Participant
should consult with the Participant’s own tax advisor regarding the tax effects of this Option and the requirements necessary to obtain favorable income tax treatment under 

  
 1 

 
Section 422 of the Code, including, but not limited to, holding period requirements. (NOTE TO PARTICIPANT: If the Option is exercised more than three (3) months after the date on which
you cease to be an Employee (other than by reason of your death or permanent and total disability as defined in Section 22(e)(3) of the Code), the Option will be treated as a Nonstatutory Stock Option and not as an Incentive Stock Option to the
extent required by Section 422 of the Code.) 
 (b)    Nonstatutory Stock Option. If the Grant Notice so
designates, this Option is intended to be a Nonstatutory Stock Option and shall not be treated as an Incentive Stock Option within the meaning of Section 422(b) of the Code. 

2.2    ISO Fair Market Value Limitation. If the Grant Notice designates this Option as an Incentive Stock Option,
then to the extent that the Option (together with all Incentive Stock Options granted to the Participant under all stock option plans of the Participating Company Group, including the Plan) becomes exercisable for the first time during any calendar
year for shares having a Fair Market Value greater than One Hundred Thousand Dollars ($100,000), the portion of such options which exceeds such amount will be treated as Nonstatutory Stock Options. For purposes of this Section, options designated as
Incentive Stock Options are taken into account in the order in which they were granted, and the Fair Market Value of stock is determined as of the time the option with respect to such stock is granted. If the Code is amended to provide for a
different limitation from that set forth in this Section, such different limitation shall be deemed incorporated herein effective as of the date required or permitted by such amendment to the Code. If the Option is treated as an Incentive Stock
Option in part and as a Nonstatutory Stock Option in part by reason of the limitation set forth in this Section, the Participant may designate which portion of such Option the Participant is exercising. In the absence of such designation, the
Participant shall be deemed to have exercised the Incentive Stock Option portion of the Option first. Separate certificates representing each such portion shall be issued upon the exercise of the Option. (NOTE TO PARTICIPANT: If the aggregate
Exercise Price of the Option (that is, the Exercise Price multiplied by the Number of Option Shares) plus the aggregate exercise price of any other Incentive Stock Options you hold (whether granted pursuant to the Plan or any other stock option plan
of the Participating Company Group) is greater than $100,000, you should contact the Chief Financial Officer of the Company to ascertain whether the entire Option qualifies as an Incentive Stock Option.) 

3.    ADMINISTRATION. 

All questions of interpretation concerning the Grant Notice, this Option Agreement, the Plan or any other form of agreement or other document
employed by the Company in the administration of the Plan or the Option shall be determined by the Board. All such determinations by the Board shall be final, binding and conclusive upon all persons having an interest in the Option, unless
fraudulent or made in bad faith. Any and all actions, decisions and determinations taken or made by the Board in the exercise of its discretion pursuant to the Plan or the Option or other agreement thereunder (other than determining questions of
interpretation pursuant to the preceding sentence) shall be final, binding and conclusive upon all persons having an interest in the Option. Any Officer shall have the authority to act on behalf of the Company with respect to any matter, right,
obligation, or election which is the responsibility of or which is allocated to the Company herein, provided the Officer has apparent authority with respect to such matter, right, obligation, or election. 

  
 2 

 4.    EXERCISE OF THE
OPTION. 
 4.1    Right to Exercise. Except as
otherwise provided herein, the Option shall be exercisable on and after the Initial Vesting Date and prior to the termination of the Option (as provided in Section 6) in an amount not to exceed the number of Vested Shares less the number of
shares previously acquired upon exercise of the Option, subject to the Company’s repurchase rights set forth in Section 11. In no event shall the Option be exercisable for more shares than the Number of Option Shares, as adjusted pursuant
to Section 9. 
 4.2    Method of Exercise. Exercise of the Option shall be by means of electronic or
written notice (the “Exercise Notice”) in a form authorized by the Company. An electronic Exercise Notice must be digitally signed or authenticated by the Participant in such manner as required by the notice and transmitted to the
Company or an authorized representative of the Company (including a third-party administrator designated by the Company). In the event that the Participant is not authorized or is unable to provide an electronic Exercise Notice, the Option shall be
exercised by a written Exercise Notice addressed to the Company, which shall be signed by the Participant and delivered in person, by certified or registered mail, return receipt requested, by confirmed facsimile transmission, or by such other means
as the Company may permit, to the Company, or an authorized representative of the Company (including a third-party administrator designated by the Company). Each Exercise Notice, whether electronic or written, must state the Participant’s
election to exercise the Option, the number of whole shares of Stock for which the Option is being exercised and such other representations and agreements as to the Participant’s investment intent with respect to such shares as may be required
pursuant to the provisions of this Option Agreement. Further, each Exercise Notice must be received by the Company prior to the termination of the Option as set forth in Section 6 and must be accompanied by full payment of the aggregate
Exercise Price for the number of shares of Stock being purchased. The Option shall be deemed to be exercised upon receipt by the Company of such electronic or written Exercise Notice and the aggregate Exercise Price. 

4.3    Payment of Exercise Price. 

(a)    Forms of Consideration Authorized. Except as otherwise provided below, payment of the aggregate Exercise
Price for the number of shares of Stock for which the Option is being exercised shall be made (i) in cash, by check or in cash equivalent, (ii) if permitted by the Company and subject to the limitations contained in Section 4.3(b), by
means of (1) a Stock Tender Exercise, (2) a Cashless Exercise or (3) a Net-Exercise; or (iii) by any combination of the foregoing. 

(b)    Limitations on Forms of Consideration. The Company reserves, at any and all times, the right, in the
Company’s sole and absolute discretion, to establish, decline to approve or terminate any program or procedure providing for payment of the Exercise Price through any of the means described below, including with respect to the Participant
notwithstanding that such program or procedures may be available to others. 

  
 3 

 (i)    Stock Tender Exercise. A “Stock Tender
Exercise” means the delivery of a properly executed Exercise Notice accompanied by (1) the Participant’s tender to the Company, or attestation to the ownership, in a form acceptable to the Company of whole shares of Stock having a
Fair Market Value that does not exceed the aggregate Exercise Price for the shares with respect to which the Option is exercised, and (2) the Participant’s payment to the Company in cash of the remaining balance of such aggregate Exercise
Price not satisfied by such shares’ Fair Market Value. A Stock Tender Exercise shall not be permitted if it would constitute a violation of the provisions of any law, regulation or agreement restricting the redemption of the Company’s
stock. If required by the Company, the Option may not be exercised by tender to the Company, or attestation to the ownership, of shares of Stock unless such shares either have been owned by the Participant for a period of time required by the
Company (and not used for another option exercise by attestation during such period) or were not acquired, directly or indirectly, from the Company. 

(ii)    Cashless Exercise. A Cashless Exercise shall be permitted only upon the class of shares subject to the
Option becoming publicly traded in an established securities market. A “Cashless Exercise” means the delivery of a properly executed Exercise Notice together with irrevocable instructions to a broker in a form acceptable to the
Company providing for the assignment to the Company of the proceeds of a sale or loan with respect to shares of Stock acquired upon the exercise of the Option in an amount not less than the aggregate Exercise Price for such shares (including,
without limitation, through an exercise complying with the provisions of Regulation T as promulgated from time to time by the Board of Governors of the Federal Reserve System). 

(iii)    Net-Exercise. A
“Net-Exercise” means the delivery of a properly executed Exercise Notice electing a procedure pursuant to which (1) the Company will reduce the number of shares otherwise issuable to the
Participant upon the exercise of the Option by the largest whole number of shares having a Fair Market Value that does not exceed the aggregate Exercise Price for the shares with respect to which the Option is exercised, and (2) the Participant
shall pay to the Company in cash the remaining balance of such aggregate Exercise Price not satisfied by such reduction in the number of whole shares to be issued. Following a Net-Exercise, the number of
shares remaining subject to the Option, if any, shall be reduced by the sum of (1) the net number of shares issued to the Participant upon such exercise, and (2) the number of shares deducted by the Company for payment of the aggregate
Exercise Price. 
 4.4    Tax Withholding. 

(a)    In General. At the time the Option is exercised, in whole or in part, or at any time thereafter as
requested by a Participating Company, the Participant hereby authorizes withholding from payroll and any other amounts payable to the Participant, and otherwise agrees to make adequate provision for any sums required to satisfy the federal, state,
local and foreign tax (including any social insurance) withholding obligations of the Participating Company Group, if any, which arise in connection with the Option. The Company shall have no obligation to deliver shares of Stock until the tax
withholding obligations of the Participating Company Group have been satisfied by the Participant. 

  
 4 

 (b)    Withholding in or Directed Sale of Shares. The Company
shall have the right, but not the obligation, to require the Participant to satisfy all or any portion of a Participating Company’s tax withholding obligations upon exercise of the Option by deducting from the shares of Stock otherwise issuable
to the Participant upon such exercise a number of whole shares having a fair market value, as determined by the Company as of the date of exercise, not in excess of the amount of such tax withholding obligations determined by the applicable minimum
statutory withholding rates. The Company may require the Participant to direct a broker, upon the exercise of the Option, to sell a portion of the shares subject to the Option determined by the Company in its discretion to be sufficient to cover the
tax withholding obligations of any Participating Company and to remit an amount equal to such tax withholding obligations to the Company in cash. 

4.5    Beneficial Ownership of Shares; Certificate Registration. The Participant hereby authorizes the Company, in
its sole discretion, to deposit for the benefit of the Participant with any broker with which the Participant has an account relationship of which the Company has notice any or all shares acquired by the Participant pursuant to the exercise of the
Option. Except as provided by the preceding sentence, a certificate for the shares as to which the Option is exercised shall be registered in the name of the Participant, or, if applicable, in the names of the heirs of the Participant. 

4.6    Restrictions on Grant of the Option and Issuance of Shares. The grant of the Option and the issuance of
shares of Stock upon exercise of the Option shall be subject to compliance with all applicable requirements of federal, state or foreign law with respect to such securities. The Option may not be exercised if the issuance of shares of Stock upon
exercise would constitute a violation of any applicable federal, state or foreign securities laws or other law or regulations or the requirements of any stock exchange or market system upon which the Stock may then be listed. In addition, the Option
may not be exercised unless (i) a registration statement under the Securities Act shall at the time of exercise of the Option be in effect with respect to the shares issuable upon exercise of the Option or (ii) in the opinion of legal
counsel to the Company, the shares issuable upon exercise of the Option may be issued in accordance with the terms of an applicable exemption from the registration requirements of the Securities Act. THE PARTICIPANT IS CAUTIONED THAT THE OPTION MAY
NOT BE EXERCISED UNLESS THE FOREGOING CONDITIONS ARE SATISFIED. ACCORDINGLY, THE PARTICIPANT MAY NOT BE ABLE TO EXERCISE THE OPTION WHEN DESIRED EVEN THOUGH THE OPTION IS VESTED. The inability of the Company to obtain from any regulatory body having
jurisdiction the authority, if any, deemed by the Company’s legal counsel to be necessary to the lawful issuance and sale of any shares subject to the Option shall relieve the Company of any liability in respect of the failure to issue or sell
such shares as to which such requisite authority shall not have been obtained. As a condition to the exercise of the Option, the Company may require the Participant to satisfy any qualifications that may be necessary or appropriate, to evidence
compliance with any applicable law or regulation and to make any representation or warranty with respect thereto as may be requested by the Company. 

4.7    Fractional Shares. The Company shall not be required to issue fractional shares upon the exercise of the
Option. 

  
 5 

 5.    NONTRANSFERABILITY OF
THE OPTION. 
 During the lifetime of the Participant, the
Option shall be exercisable only by the Participant or the Participant’s guardian or legal representative. The Option shall not be subject in any manner to anticipation, alienation, sale, exchange, transfer, assignment, pledge, encumbrance, or
garnishment by creditors of the Participant or the Participant’s beneficiary, except transfer by will or by the laws of descent and distribution. Following the death of the Participant, the Option, to the extent provided in Section 7, may
be exercised by the Participant’s legal representative or by any person empowered to do so under the deceased Participant’s will or under the then applicable laws of descent and distribution. 

6.    TERMINATION OF THE
OPTION. 
 The Option shall terminate and may no longer be exercised
after the first to occur of (a) the close of business on the Option Expiration Date, (b) the close of business on the last date for exercising the Option following termination of the Participant’s Service as described in
Section 7, or (c) a Change in Control to the extent provided in Section 8. 

7.    EFFECT OF TERMINATION OF
SERVICE. 
 7.1    Option Exercisability. The
Option shall terminate immediately upon the Participant’s termination of Service to the extent that it is then unvested and shall be exercisable after the Participant’s termination of Service to the extent it is then vested only during the
applicable time period as determined below and thereafter shall terminate. 
 (a)    Disability. If the
Participant’s Service terminates because of the Disability of the Participant, the Option, to the extent unexercised and exercisable for Vested Shares on the date on which the Participant’s Service terminated, may be exercised by the
Participant (or the Participant’s guardian or legal representative) at any time prior to the expiration of twelve (12) months after the date on which the Participant’s Service terminated, but in any event no later than the Option
Expiration Date. 
 (b)    Death. If the Participant’s Service terminates because of the death of the
Participant, the Option, to the extent unexercised and exercisable for Vested Shares on the date on which the Participant’s Service terminated, may be exercised by the Participant’s legal representative or other person who acquired the
right to exercise the Option by reason of the Participant’s death at any time prior to the expiration of twelve (12) months after the date on which the Participant’s Service terminated, but in any event no later than the Option
Expiration Date. The Participant’s Service shall be deemed to have terminated on account of death if the Participant dies within three (3) months after the Participant’s termination of Service. 

(c)    Termination for Cause. Notwithstanding any other provision of this Option Agreement, if the
Participant’s Service is terminated for Cause, the Option shall terminate in its entirety and cease to be exercisable immediately upon such termination of Service. 

(d)    Other Termination of Service. If the Participant’s Service terminates for any reason, except
Disability, death or Cause, the Option, to the extent 

  
 6 

 
unexercised and exercisable for Vested Shares by the Participant on the date on which the Participant’s Service terminated, may be exercised by the Participant at any time prior to the
expiration of three (3) months after the date on which the Participant’s Service terminated, but in any event no later than the Option Expiration Date. 

7.2    Extension if Exercise Prevented by Law. Notwithstanding the foregoing other than termination of the
Participant’s Service for Cause, if the exercise of the Option within the applicable time periods set forth in Section 7.1 is prevented by the provisions of Section 4.6, the Option shall remain exercisable until the later of
(a) thirty (30) days after the date such exercise first would no longer be prevented by such provisions or (b) the end of the applicable time period under Section 7.1, but in any event no later than the Option Expiration Date.

 8.    EFFECT OF CHANGE IN
CONTROL. 
 In the event of a Change in Control, except to the extent
that the Board determines to settle the Option in accordance with Section 9.1(c) of the Plan, the surviving, continuing, successor, or purchasing corporation or other business entity or parent thereof, as the case may be (the
“Acquiror”), may, without the consent of the Participant, assume or continue in full force and effect the Company’s rights and obligations under all or any portion of the Option or substitute for all or any portion of the
Option a substantially equivalent option for the Acquiror’s stock. For purposes of this Section, the Option or any portion thereof shall be deemed assumed if, following the Change in Control, the Option confers the right to receive, subject to
the terms and conditions of the Plan and this Option Agreement, for each share of Stock subject to such portion of the Option immediately prior to the Change in Control, the consideration (whether stock, cash, other securities or property or a
combination thereof) to which a holder of a share of Stock on the effective date of the Change in Control was entitled (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the
outstanding shares of Stock); provided, however, that if such consideration is not solely common stock of the Acquiror, the Board may, with the consent of the Acquiror, provide for the consideration to be received upon the exercise of the Option for
each share of Stock to consist solely of common stock of the Acquiror equal in Fair Market Value to the per share consideration received by holders of Stock pursuant to the Change in Control. If any portion of such consideration may be received by
holders of Stock pursuant to the Change in Control on a contingent or delayed basis, the Board may, in its discretion, determine such Fair Market Value per share as of the time of the Change in Control on the basis of the Board’s good faith
estimate of the present value of the probable future payment of such consideration. The Option shall terminate and cease to be outstanding effective as of the time of consummation of the Change in Control to the extent that the Option is neither
assumed or continued by the Acquiror in connection with the Change in Control nor exercised as of the time of the Change in Control. Notwithstanding the foregoing, shares acquired upon exercise of the Option prior to the Change in Control and any
consideration received pursuant to the Change in Control with respect to such shares shall continue to be subject to all applicable provisions of this Option Agreement except as otherwise provided herein. 

  
 7 

 9.    ADJUSTMENTS FOR
CHANGES IN CAPITAL STRUCTURE. 

Subject to any required action by the shareholders of the Company and the requirements of Sections 409A and 424 of the Code to the extent
applicable, in the event of any change in the Stock effected without receipt of consideration by the Company, whether through merger, consolidation, reorganization, reincorporation, recapitalization, reclassification, stock dividend, stock split,
reverse stock split, split-up, split-off, spin-off, combination of shares, exchange of shares, or similar change in the capital
structure of the Company, or in the event of payment of a dividend or distribution to the shareholders of the Company in a form other than Stock (excepting normal cash dividends) that has a material effect on the Fair Market Value of shares of
Stock, appropriate and proportionate adjustments shall be made in the number, Exercise Price and kind of shares subject to the Option, in order to prevent dilution or enlargement of the Participant’s rights under the Option. For purposes of the
foregoing, conversion of any convertible securities of the Company shall not be treated as “effected without receipt of consideration by the Company.” Any fractional share resulting from an adjustment pursuant to this Section shall be
rounded down to the nearest whole number, and the Exercise Price shall be rounded up to the nearest whole cent. In no event may the Exercise Price be decreased to an amount less than the par value, if any, of the stock subject to the Option. Such
adjustments shall be determined by the Board, and its determination shall be final, binding and conclusive. 

10.    RIGHTS AS A SHAREHOLDER, DIRECTOR,
EMPLOYEE OR CONSULTANT. 
 The Participant
shall have no rights as a shareholder with respect to any shares covered by the Option until the date of the issuance of the shares for which the Option has been exercised (as evidenced by the appropriate entry on the books of the Company or of a
duly authorized transfer agent of the Company). No adjustment shall be made for dividends, distributions or other rights for which the record date is prior to the date the shares are issued, except as provided in Section 9. If the Participant
is an Employee, the Participant understands and acknowledges that, except as otherwise provided in a separate, written employment agreement between a Participating Company and the Participant, the Participant’s employment is “at will”
and is for no specified term. Nothing in this Option Agreement shall confer upon the Participant any right to continue in the Service of a Participating Company or interfere in any way with any right of the Participating Company Group to terminate
the Participant’s Service as a Director, an Employee or Consultant, as the case may be, at any time. 

11.    RIGHT OF FIRST
REFUSAL. 
 11.1    Grant of Right of First
Refusal. Except as provided in Section 11.7 and Section 16 below, in the event the Participant, the Participant’s legal representative, or other holder of shares acquired upon exercise of the Option proposes to sell, exchange,
transfer, pledge, or otherwise dispose of any Vested Shares (the “Transfer Shares”) to any person or entity, including, without limitation, any shareholder of a Participating Company, the Company shall have the right to repurchase
the Transfer Shares under the terms and subject to the conditions set forth in this Section 11 (the “Right of First Refusal”). 

11.2    Notice of Proposed Transfer. Prior to any proposed transfer of the Transfer Shares, the Participant shall
deliver written notice (the “Transfer Notice”) to the 

  
 8 

 
Company describing fully the proposed transfer, including the number of Transfer Shares, the name and address of the proposed transferee (the “Proposed Transferee”) and, if the
transfer is voluntary, the proposed transfer price, and containing such information necessary to show the bona fide nature of the proposed transfer. In the event of a bona fide gift or involuntary transfer, the proposed transfer price shall be
deemed to be the Fair Market Value of the Transfer Shares, as determined by the Board in good faith. If the Participant proposes to transfer any Transfer Shares to more than one Proposed Transferee, the Participant shall provide a separate Transfer
Notice for the proposed transfer to each Proposed Transferee. The Transfer Notice shall be signed by both the Participant and the Proposed Transferee and must constitute a binding commitment of the Participant and the Proposed Transferee for the
transfer of the Transfer Shares to the Proposed Transferee subject only to the Right of First Refusal. 

11.3    Bona Fide Transfer. If the Company determines that the information provided by the Participant in the
Transfer Notice is insufficient to establish the bona fide nature of a proposed voluntary transfer, the Company shall give the Participant written notice of the Participant’s failure to comply with the procedure described in this
Section 11, and the Participant shall have no right to transfer the Transfer Shares without first complying with the procedure described in this Section 11. The Participant shall not be permitted to transfer the Transfer Shares if the
proposed transfer is not bona fide. 
 11.4    Exercise of Right of First Refusal. If the Company determines the
proposed transfer to be bona fide, the Company shall have the right to purchase all, but not less than all, of the Transfer Shares (except as the Company and the Participant otherwise agree) at the purchase price and on the terms set forth in the
Transfer Notice by delivery to the Participant of a notice of exercise of the Right of First Refusal within thirty (30) days after the date the Transfer Notice is delivered to the Company. The Company’s exercise or failure to exercise the
Right of First Refusal with respect to any proposed transfer described in a Transfer Notice shall not affect the Company’s right to exercise the Right of First Refusal with respect to any proposed transfer described in any other Transfer
Notice, whether or not such other Transfer Notice is issued by the Participant or issued by a person other than the Participant with respect to a proposed transfer to the same Proposed Transferee. If the Company exercises the Right of First Refusal,
the Company and the Participant shall thereupon consummate the sale of the Transfer Shares to the Company on the terms set forth in the Transfer Notice within sixty (60) days after the date the Transfer Notice is delivered to the Company
(unless a longer period is offered by the Proposed Transferee); provided, however, that in the event the Transfer Notice provides for the payment for the Transfer Shares other than in cash, the Company shall have the option of paying for the
Transfer Shares by the present value cash equivalent of the consideration described in the Transfer Notice as reasonably determined by the Company. For purposes of the foregoing, cancellation of any indebtedness of the Participant to any
Participating Company shall be treated as payment to the Participant in cash to the extent of the unpaid principal and any accrued interest canceled. Notwithstanding anything contained in this Section to the contrary, the period during which the
Company may exercise the Right of First Refusal and consummate the purchase of the Transfer Shares from the Participant shall terminate no sooner than the completion of a period of eight (8) months following the date on which the Participant
acquired the Transfer Shares upon exercise of the Option. 

  
 9 

 11.5    Failure to Exercise Right of First Refusal. If the
Company fails to exercise the Right of First Refusal in full (or to such lesser extent as the Company and the Participant otherwise agree) within the period specified in Section 11.4 above, the Participant may conclude a transfer to the
Proposed Transferee of the Transfer Shares on the terms and conditions described in the Transfer Notice, provided such transfer occurs not later than ninety (90) days following delivery to the Company of the Transfer Notice or, if applicable,
following the end of the period described in the last sentence of Section 11.4. The Company shall have the right to demand further assurances from the Participant and the Proposed Transferee (in a form satisfactory to the Company) that the
transfer of the Transfer Shares was actually carried out on the terms and conditions described in the Transfer Notice. No Transfer Shares shall be transferred on the books of the Company until the Company has received such assurances, if so
demanded, and has approved the proposed transfer as bona fide. Any proposed transfer on terms and conditions different from those described in the Transfer Notice, as well as any subsequent proposed transfer by the Participant, shall again be
subject to the Right of First Refusal and shall require compliance by the Participant with the procedure described in this Section 11. 

11.6    Transferees of Transfer Shares. All transferees of the Transfer Shares or any interest therein, other than
the Company, shall be required as a condition of such transfer to agree in writing (in a form satisfactory to the Company) that such transferee shall receive and hold such Transfer Shares or interest therein subject to all of the terms and
conditions of this Option Agreement, including this Section 11 providing for the Right of First Refusal with respect to any subsequent transfer. Any sale or transfer of any shares acquired upon exercise of the Option shall be void unless the
provisions of this Section 11 are met. 
 11.7    Transfers Not Subject to Right of First Refusal. The Right
of First Refusal shall not apply to any transfer or exchange of the shares acquired upon exercise of the Option if such transfer or exchange is in connection with an Ownership Change Event. If the consideration received pursuant to such transfer or
exchange consists of stock of a Participating Company, such consideration shall remain subject to the Right of First Refusal unless the provisions of Section 11.9 result in a termination of the Right of First Refusal. 

11.8    Assignment of Right of First Refusal. The Company shall have the right to assign the Right of First Refusal
at any time, whether or not there has been an attempted transfer, to one or more persons as may be selected by the Company. 

11.9    Early Termination of Right of First Refusal. The other provisions of this Option Agreement notwithstanding,
the Right of First Refusal shall terminate and be of no further force and effect upon (a) the occurrence of a Change in Control, unless the Acquiror assumes the Company’s rights and obligations under the Option or substitutes a
substantially equivalent option for the Acquiror’s stock for the Option, or (b) the existence of a public market for the class of shares subject to the Right of First Refusal. A “public market” shall be deemed to exist if
(i) such stock is listed on a national securities exchange (as that term is used in the Exchange Act) or (ii) such stock is traded on the over-the-counter
market and prices therefor are published daily on business days in a recognized financial journal. 

  
 10 

 12.    STOCK DISTRIBUTIONS
SUBJECT TO OPTION AGREEMENT. 

If, from time to time, there is any stock dividend, stock split or other change, as described in Section 9, in the character or amount of
any of the outstanding stock of the corporation the stock of which is subject to the provisions of this Option Agreement, then in such event any and all new, substituted or additional securities to which the Participant is entitled by reason of the
Participant’s ownership of the shares acquired upon exercise of the Option shall be immediately subject to the Right of First Refusal with the same force and effect as the shares subject to the Right of First Refusal immediately before such
event. 
 13.    NOTICE OF SALES UPON
DISQUALIFYING DISPOSITION. 
 The Participant shall
dispose of the shares acquired pursuant to the Option only in accordance with the provisions of this Option Agreement. In addition, if the Grant Notice designates this Option as an Incentive Stock Option, the Participant shall (a) promptly
notify the Chief Financial Officer of the Company if the Participant disposes of any of the shares acquired pursuant to the Option within one (1) year after the date the Participant exercises all or part of the Option or within two
(2) years after the Date of Grant and (b) provide the Company with a description of the circumstances of such disposition. Until such time as the Participant disposes of such shares in a manner consistent with the provisions of this Option
Agreement, unless otherwise expressly authorized by the Company, the Participant shall hold all shares acquired pursuant to the Option in the Participant’s name (and not in the name of any nominee) for the
one-year period immediately after the exercise of the Option and the two-year period immediately after Date of Grant. At any time during the one-year or two-year periods set forth above, the Company may place a legend on any certificate representing shares acquired pursuant to the Option requesting the transfer
agent for the Company’s stock to notify the Company of any such transfers. The obligation of the Participant to notify the Company of any such transfer shall continue notwithstanding that a legend has been placed on the certificate pursuant to
the preceding sentence. 
 14.    LEGENDS. 

The Company may at any time place legends referencing the Right of First Refusal and any applicable federal, state or foreign securities law
restrictions on all certificates representing shares of stock subject to the provisions of this Option Agreement. The Participant shall, at the request of the Company, promptly present to the Company any and all certificates representing shares
acquired pursuant to the Option in the possession of the Participant in order to carry out the provisions of this Section. Unless otherwise specified by the Company, legends placed on such certificates may include, but shall not be limited to, the
following: 
 14.1    “THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, TRANSFERRED, ASSIGNED OR HYPOTHECATED UNLESS THERE IS AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT COVERING SUCH SECURITIES, THE SALE IS MADE IN ACCORDANCE WITH RULE 144 OR RULE 701 UNDER THE
ACT, OR THE COMPANY RECEIVES AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE COMPANY, STATING THAT SUCH SALE, TRANSFER, ASSIGNMENT OR HYPOTHECATION IS EXEMPT FROM THE REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF SUCH ACT.” 

  
 11 

 14.2    “THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO
CERTAIN RESTRICTIONS ON TRANSFER AND REPURCHASE OPTIONS IN FAVOR OF THE CORPORATION OR ITS ASSIGNEE SET FORTH IN AN AGREEMENT BETWEEN THE CORPORATION AND THE REGISTERED HOLDER, OR SUCH HOLDER’’S PREDECESSOR IN INTEREST, A COPY OF WHICH IS
ON FILE AT THE PRINCIPAL OFFICE OF THIS CORPORATION.” 
 14.3    “THE SHARES EVIDENCED BY THIS CERTIFICATE
WERE ISSUED BY THE CORPORATION TO THE REGISTERED HOLDER UPON EXERCISE OF AN INCENTIVE STOCK OPTION AS DEFINED IN SECTION 422 OF THE INTERNAL REVENUE CODE OF 1986, AS AMENDED (“ISO”). IN ORDER TO OBTAIN THE PREFERENTIAL TAX TREATMENT
AFFORDED TO ISOs, THE SHARES SHOULD NOT BE TRANSFERRED PRIOR TO [INSERT DISQUALIFYING DISPOSITION DATE HERE]. SHOULD THE REGISTERED HOLDER ELECT TO TRANSFER ANY OF THE SHARES PRIOR TO THIS DATE AND FOREGO ISO TAX TREATMENT, THE TRANSFER AGENT FOR
THE SHARES SHALL NOTIFY THE CORPORATION IMMEDIATELY. THE REGISTERED HOLDER SHALL HOLD ALL SHARES PURCHASED UNDER THE INCENTIVE STOCK OPTION IN THE REGISTERED HOLDER’S NAME (AND NOT IN THE NAME OF ANY NOMINEE) PRIOR TO THIS DATE OR UNTIL
TRANSFERRED AS DESCRIBED ABOVE.” 

15.    LOCK-UP
AGREEMENT. 
 The Participant hereby agrees that in the event of any
underwritten public offering of stock, including an initial public offering of stock, made by the Company pursuant to an effective registration statement filed under the Securities Act, the Participant shall not offer, sell, contract to sell,
pledge, hypothecate, grant any option to purchase or make any short sale of, or otherwise dispose of any shares of stock of the Company or any rights to acquire stock of the Company for such period of time from and after the effective date of such
registration statement as may be established by the underwriter for such public offering; provided, however, that such period of time shall not exceed one hundred eighty (180) days from the effective date of the registration statement to be
filed in connection with such public offering. The foregoing limitation shall not apply to shares registered in the public offering under the Securities Act (and for such additional period, not to exceed 34 days, after the expiration of the 180-day period, as the underwriters of the Company shall request in order to facilitate compliance with NASD Rule 2711). The Participant hereby agrees to enter into any agreement reasonably required by the
underwriters to implement the foregoing within a reasonable timeframe if so requested by the Company. 

16.    RESTRICTIONS ON TRANSFER OF
SHARES. 
 No shares acquired upon exercise of the Option may be sold,
exchanged, transferred (including, without limitation, any transfer to a nominee or agent of the Participant), assigned, pledged, hypothecated or otherwise disposed of, including by operation of law in any manner

  
 12 

 
which violates any of the provisions of this Option Agreement, and any such attempted disposition shall be void. The Company shall not be required (a) to transfer on its books any shares
which will have been transferred in violation of any of the provisions set forth in this Option Agreement or (b) to treat as owner of such shares or to accord the right to vote as such owner or to pay dividends to any transferee to whom such
shares will have been so transferred. 
 17.    MISCELLANEOUS
PROVISIONS. 
 17.1    Termination or
Amendment. The Board may terminate or amend the Plan or the Option at any time; provided, however, that except as provided in Section 8 in connection with a Change in Control, no such termination or amendment may adversely affect the Option
or any unexercised portion hereof without the consent of the Participant unless such termination or amendment is necessary to comply with any applicable law or government regulation, including, but not limited to Section 409A of the Code. No
amendment or addition to this Option Agreement shall be effective unless in writing. 
 17.2    Compliance with
Section 409A. The Company intends that income realized by the Participant pursuant to the Plan and this Option Agreement will not be subject to taxation under Section 409A of the Code. The provisions of the Plan and this
Option Agreement shall be interpreted and construed in favor of satisfying any applicable requirements of Section 409A of the Code. The Company, in its reasonable discretion, may amend (including retroactively) the Plan and this Agreement in
order to conform to the applicable requirements of Section 409A of the Code, including amendments to facilitate the Participant’s ability to avoid taxation under Section 409A of the Code. However, the preceding provisions shall not
be construed as a guarantee by the Company of any particular tax result for income realized by the Participant pursuant to the Plan or this Option Agreement. In any event, and except for the responsibilities of the Company set forth in
Section 4.4, no Participating Company shall be responsible for the payment of any applicable taxes incurred by the Participant on income realized by the Participant pursuant to the Plan or this Option Agreement. 

17.3    Further Instruments. The parties hereto agree to execute such further instruments and to take such further
action as may reasonably be necessary to carry out the intent of this Option Agreement. 
 17.4    Binding
Effect. This Option Agreement shall inure to the benefit of the successors and assigns of the Company and, subject to the restrictions on transfer set forth herein, be binding upon the Participant and the Participant’s heirs, executors,
administrators, successors and assigns. 
 17.5    Delivery of Documents and Notices. Any document relating to
participation in the Plan, or any notice required or permitted hereunder shall be given in writing and shall be deemed effectively given (except to the extent that this Option Agreement provides for effectiveness only upon actual receipt of such
notice) upon personal delivery, electronic delivery at the e-mail address, if any, provided for the Participant by a Participating Company, or upon deposit in the U.S. Post Office or foreign postal service, by
registered or certified mail, or with a nationally recognized overnight courier service, with postage and fees prepaid, addressed to the other party at the address of such party set forth in the Grant Notice or at such other address as such party
may designate in writing from time to time to the other party. 

  
 13 

 (a)    Description of Electronic Delivery. The Plan
documents, which may include but do not necessarily include: the Plan, the Grant Notice, this Option Agreement, and any reports of the Company provided generally to the Company’s shareholders, may be delivered to the Participant electronically.
In addition, if permitted by the Company, the Participant may deliver electronically the Grant Notice and Exercise Notice called for by Section 4.2 to the Company or to such third party involved in administering the Plan as the Company may
designate from time to time. Such means of electronic delivery may include but do not necessarily include the delivery of a link to a Company intranet or the Internet site of a third party involved in administering the Plan, the delivery of the
document via e-mail or such other means of electronic delivery specified by the Company. 

(b)    Consent to Electronic Delivery. The Participant acknowledges that the Participant has read
Section 17.5(a) of this Option Agreement and consents to the electronic delivery of the Plan documents and, if permitted by the Company, the delivery of the Grant Notice and Exercise Notice, as described in Section 17.5(a). The Participant
acknowledges that he or she may receive from the Company a paper copy of any documents delivered electronically at no cost to the Participant by contacting the Company by telephone or in writing. The Participant further acknowledges that the
Participant will be provided with a paper copy of any documents if the attempted electronic delivery of such documents fails. Similarly, the Participant understands that the Participant must provide the Company or any designated third party
administrator with a paper copy of any documents if the attempted electronic delivery of such documents fails. The Participant may revoke his or her consent to the electronic delivery of documents described in Section 17.5(a) or may change the
electronic mail address to which such documents are to be delivered (if Participant has provided an electronic mail address) at any time by notifying the Company of such revoked consent or revised e-mail
address by telephone, postal service or electronic mail. Finally, the Participant understands that he or she is not required to consent to electronic delivery of documents described in Section 17.5(a). 

17.6    Integrated Agreement. The Grant Notice, this Option Agreement and the Plan, together with any employment,
service or other agreement with the Participant and a Participating Company referring to the Option, shall constitute the entire understanding and agreement of the Participant and the Participating Company Group with respect to the subject matter
contained herein or therein and supersede any prior agreements, understandings, restrictions, representations, or warranties among the Participant and the Participating Company Group with respect to such subject matter. To the extent contemplated
herein or therein, the provisions of the Grant Notice, the Option Agreement and the Plan shall survive any exercise of the Option and shall remain in full force and effect. 

17.7    Applicable Law. This Option Agreement shall be governed by the laws of the State of Washington as such laws
are applied to agreements between Washington residents entered into and to be performed entirely within the State of Washington.

Ladies and Gentlemen: 

1.    Option. I was granted an option (the “Option”) to purchase shares of the

	My Social Security Number is:	 	  

 6.    Notice of Disqualifying Disposition. If the Option is an
Incentive Stock Option, I agree that I will promptly notify the Chief Financial Officer of the Company if I transfer any of the Shares within one (1) year from the date I exercise all or part of the Option or within two (2) years of the
Date of Grant. 
 7.    Binding Effect. I agree that the Shares are being acquired in accordance
with and subject to the terms, provisions and conditions of the Grant Notice, the Option Agreement, including the Right of First Refusal set forth therein, and the Plan, to all of which I hereby expressly assent. This Agreement shall inure to the
benefit of and be binding upon my heirs, executors, administrators, successors and assigns. 

8.    Transfer. I understand and acknowledge that the Shares have not been registered under the
Securities Act of 1933, as amended (the “Securities Act”), and that consequently the Shares must be held indefinitely unless they are subsequently registered under the Securities Act, an exemption from such registration is
available, or they are sold in accordance with Rule 144 or Rule 701 under the Securities Act. I further understand and acknowledge that the Company is under no obligation to register the Shares. I understand that the certificate or
certificates evidencing the Shares will be imprinted with legends which prohibit the transfer of the Shares unless they are registered or such registration is not required in the opinion of legal counsel satisfactory to the Company. 

I am aware that Rule 144 under the Securities Act, which permits limited public resale of securities acquired in a nonpublic offering, is
not currently available with respect to the Shares and, in any event, is available only if certain conditions are satisfied. I understand that any sale of the Shares that might be made in reliance upon Rule 144 may only be made in limited
amounts in accordance with the terms and conditions of such rule and that a copy of Rule 144 will be delivered to me upon request. 
 I
understand that I am purchasing the Shares pursuant to the terms of the Plan, the Grant Notice and my Option Agreement, copies of which I have received and carefully read and understand. 

 

			
	Very truly yours,
	
	  

	(Signature)
