security of the Company is registered pursuant to Section 12 of the Exchange Act, the Plan shall be administered in compliance with the requirements, if any, of Rule 16b-3.

employees of the Participating Company Group, members of the Board and any officers or employees of the Participating 

  
 7 








 
Company Group to whom authority to act for the Board or 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 31,816,886 and shall consist of authorized but unissued or reacquired shares of Stock or any combination thereof. 

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 are acquired pursuant to an Award subject to forfeiture or repurchase and are forfeited or repurchased by the Company for an amount not greater than the Participant’s exercise or 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 (a) with
respect to any portion of an Award that is settled in cash or (b) to the extent such shares are withheld or reacquired by the Company in satisfaction of tax withholding obligations pursuant to Section 10.2. 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 net number of
shares issued upon the exercise of the Option. 
 4.3 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 regular, periodic 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 ISO Share Limit set forth in Section 5.3(a), and in the exercise or purchase
price per share under any outstanding Awards in order to prevent dilution or 

  
 8 








 
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 Board 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 Board, in its discretion. Any fractional share resulting from
an adjustment pursuant to this Section shall be rounded down to the nearest whole number, and the exercise price per share shall be rounded up to the nearest whole cent. In no event may the exercise or purchase price, if any, under any Award be
decreased to an amount less than the par value, if any, of the stock subject to the Award. Such adjustments shall be determined by the Board, and its determination shall be final, binding and conclusive. 

4.4 Assumption or Substitution of Awards. The Board may, without affecting the number of shares of Stock available pursuant to
Section 4.1, 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 OPTION 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 Board. 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 Section 4.1 and adjustment as provided in
Section 4.2, 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 three million three hundred eighty nine thousand ten (3,389,010) shares
(the “ISO Share Limit”). 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 Section 4.2. 
 (b) Persons Eligible. An Incentive Stock
Option may be granted only to a person who, on the effective date of grant, is an Employee. Any person who is not an 

  
 9 








 
Employee 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 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
portions of such options which exceed 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 of the Option, Shares issued pursuant to each such portion shall be separately identified. 

6. STOCK OPTIONS. 

Options shall be evidenced by Award Agreements specifying the number of shares of Stock covered thereby, in such form as the Board shall from
time to time establish. Such Award Agreements 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 Board; provided,
however, that (a) the exercise price per share for an Option 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
Shareholder 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 409A or Section 424(a) of the Code, as applicable. 
 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 Board 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, (b) no Incentive Stock Option granted to a Ten
Percent Shareholder shall be exercisable after the expiration of five (5) years after the effective date of grant of such Option, and (c) no Option granted to an Employee who is a non-exempt employee for purposes of the Fair Labor
Standards 

  
 10 








 
Act of 1938, as amended, shall be first exercisable until at least six (6) months following the date of grant of such Option (except in the event of such Employee’s death, disability or
retirement, upon a Change in Control, or as otherwise permitted by the Worker Economic Opportunity Act). Subject to the foregoing, unless otherwise specified by the Board 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) if permitted by the Company and subject to the limitations contained in Section 6.3(b), by
means of (1) a Stock Tender Exercise, (2) a Cashless Exercise or (3) a Net Exercise; (iii) by such other consideration as may be approved by the Board from time to time to the extent permitted by applicable law, or (iv) by
any combination thereof. The Board 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. 
 (b) Limitations on Forms of Consideration. 

(i) Stock Tender Exercise. A “Stock Tender Exercise” means the delivery of a properly executed
exercise notice accompanied by a 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. 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 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). 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. 

  
 11 








 (iii) Net Exercise. A “Net Exercise” means the
delivery of a properly executed exercise notice followed by a procedure pursuant to which (1) the Company will reduce the number of shares otherwise issuable to a Participant upon the exercise of an 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. 
 6.4 Effect of Termination of Service. 

(a) Option Exercisability. Subject to earlier termination of the Option as otherwise provided by this Plan and unless a
longer exercise period is provided by the Board, 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. 

(iii) Termination for Cause. Notwithstanding any other provision of the Plan to the contrary, 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. 

(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. 

  
 12 








 (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 11 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 Board, 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 Rule 701 under the Securities Act and the General Instructions to Form S-8 Registration Statement 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. 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 Board shall from time to time establish. Such Award Agreements 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 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 Board shall determine, including, without limitation, upon the attainment of one or more
performance goals. 
 7.2 Purchase Price. The purchase price for shares of Stock issuable under each Restricted Stock Purchase Right
shall be established by the Board 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. 

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

  
 13 








 7.4 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 Board from time to
time to the extent permitted by applicable law, or (c) by any combination thereof. 
 7.5 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, as shall be established by the
Board 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 7.8. The Board, 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. 
 7.6 Voting Rights; Dividends and Distributions. Except as provided in this Section,
Section 7.5 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 shareholder 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 Board 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, and otherwise shall be paid no later than the end of the calendar
year in which such dividends or distributions are paid to shareholders (or, if later, the 15th day of the third month following the date such dividends or distributions are paid to shareholders). 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 4.2, any and all new, substituted or additional securities or other property (other than regular,
periodic 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. 
 7.7 Effect of Termination of Service. Unless otherwise
provided by the Board in the Award Agreement evidencing a Restricted Stock Award, if a Participant’s 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 

  
 14 








 
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. 

7.8 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. 

8. STANDARD FORMS OF AWARD AGREEMENTS.

 8.1 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 Board 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. 
 8.2 Authority to Vary Terms. The Board 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. 

9. CHANGE IN CONTROL. 

9.1 Effect of Change in Control on Awards. Subject to the requirements and limitations of Section 409A of the Code,
if applicable, the Board may provide for any one or more of the following: 
 (a) Accelerated Vesting. In its discretion, the
Board 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 and/or vesting 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 Board shall determine. 

(b) Assumption, Continuation or Substitution of Awards. 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, assume or continue the Company’s rights and
obligations under each 

  
 15 








 
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. For purposes of this Section, if so determined by the Board, in its discretion, an Award or any portion thereof 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 such portion of 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 (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 Award 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. Any Award or portion thereof which is neither assumed or continued by the Acquiror in connection with the Change in Control nor
exercised 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. Notwithstanding the foregoing, shares acquired upon exercise of an Award
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 the Award Agreement evidencing such Award except as otherwise
provided in such Award Agreement. 
 (c) Cash-Out of Outstanding Awards. The Board 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 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 Board) 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. 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
sole 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 amount of future payment of such consideration. In the
event such determination is made by the Board, 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 

  
 16 








 
Control and in respect of the unvested portions of their canceled Awards in accordance with the vesting schedules applicable to such Awards. 

9.2 Federal Excise Tax Under Section 4999 of the Code. 

(a) Excess Parachute Payment. If 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 due to the characterization of such acceleration of vesting, payment or benefit as an “excess parachute payment”
under Section 280G of the Code, then, provided such election would not subject the Participant to taxation under Section 409A of the Code, the Participant may elect, in his or her sole discretion, 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 9.2(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 9.2(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. 

10. TAX WITHHOLDING. 

10.1 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 any social insurance tax), if any, required by law to be withheld by the Participating
Company Group with respect to an Award or the shares acquired pursuant thereto. The Company shall have no obligation to deliver shares of Stock or to release shares of Stock from an escrow established pursuant to an Award Agreement until the
Participating Company Group’s tax withholding obligations have been satisfied by the Participant. 
 10.2 Withholding in or Directed
Sale of 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 vesting 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 the Participating Company Group. The Fair Market Value of any shares of Stock withheld or tendered to satisfy
any such tax withholding 

  
 17 








 
obligations shall not exceed the amount determined by the applicable minimum statutory withholding rates. The Company may require a Participant to direct a broker, upon the vesting or exercise of
an Award, to sell a portion of the shares subject to the Award 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. 
 11. 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. 

12. AMENDMENT OR TERMINATION OF PLAN.

 The Board may amend, suspend or terminate the Plan at any time. However, without the approval of the Company’s shareholders, 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 4.2), (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 shareholders 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 Board. Except as provided by the next sentence, no amendment, suspension or termination
of the Plan may have a materially adverse effect on any then outstanding Award without the consent of the Participant. Notwithstanding any other provision of the Plan or any Award Agreement to the contrary, the Board 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 of the Code. 

  
 18 








 13. MISCELLANEOUS PROVISIONS. 

13.1 Repurchase Rights. Shares issued under the Plan may be subject to a right of first refusal, one or more repurchase
options, or other conditions and restrictions as determined by the Board 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. 

13.2 Forfeiture Events. The Board 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. 

13.3 Provision of Information. At least annually, copies of the Company’s balance sheet and income statement for the just completed
fiscal year shall be made available to each Participant and purchaser of shares of Stock upon the exercise of an Award; provided, however, that this requirement shall not apply if all offers and sales of securities pursuant to the Plan comply with
all applicable conditions of Rule 701 under the Securities Act. The Company shall not be required to provide such information to key persons whose duties in connection with the Company assure them access to equivalent information. The Company shall
deliver to each Participant such disclosures as are required in accordance with Rule 701 under the Securities Act. 
 13.4 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. 
 13.5 Rights as a Shareholder. A Participant shall have no rights as a shareholder
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 4.2 or another provision of the Plan. 

  
 19 








 13.6 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. 
 13.7 Fractional Shares. The Company shall not be required
to issue fractional shares upon the exercise or settlement of any Award. 
 13.8 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 benefits. 

13.9 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. 
 13.10 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. 

13.11 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 California, without regard to its conflict of law rules. 

13.12 Shareholder Approval. The Plan or any increase in the maximum aggregate number of shares of Stock issuable thereunder as provided
in Section 4.1 (the “Authorized Shares”) shall be approved by a majority of the outstanding securities of the Company entitled to vote by the later of (a) a period beginning twelve (12) months before and ending
twelve (12) months after the date of adoption thereof by the Board or (b) the first issuance of any security pursuant to the Plan in the State of California (within the meaning of Section 25008 of the California Corporations Code).
Awards granted prior to security holder approval of the Plan or in excess of the Authorized Shares previously approved by the security holders shall become exercisable no earlier than the date of security holder approval of the Plan or such increase
in the Authorized Shares, as the case may be, and such Awards shall be 

  
 20 








 
rescinded if such security holder approval is not received in the manner described in the preceding sentence. 

IN WITNESS WHEREOF, the undersigned Secretary of the Company certifies that the foregoing sets forth the DermTech International 2010 Stock
Plan as duly adopted by the Board on July 29, 2010.

 THE SECURITIES WHICH ARE THE SUBJECT OF THIS AGREEMENT HAVE NOT BEEN QUALIFIED WITH THE COMMISSIONER OF
CORPORATIONS OF THE STATE OF CALIFORNIA AND THE ISSUANCE OF SUCH SECURITIES OR THE PAYMENT OR RECEIPT OF ANY PART OF THE CONSIDERATION THEREFOR PRIOR TO SUCH QUALIFICATION IS UNLAWFUL, UNLESS THE SALE OF SECURITIES IS EXEMPT FROM QUALIFICATION BY
SECTION 25100, 25102, OR 25105 OF THE CALIFORNIA CORPORATIONS CODE. THE RIGHTS OF ALL PARTIES TO THIS AGREEMENT ARE EXPRESSLY CONDITIONED UPON SUCH QUALIFICATION BEING OBTAINED, UNLESS THE SALE IS SO EXEMPT. 

THE SECURITIES THAT ARE THE SUBJECT OF THIS AGREEMENT HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR
DISTRIBUTION THEREOF. NO SUCH SALE OR DISPOSITION MAY BE EFFECTED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES ACT OF
1933. 
 DERMTECH INTERNATIONAL 

STOCK OPTION AGREEMENT 

DermTech International 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 DermTech International 2010 Stock 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. 

  
 1 








 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 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. 

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. 
 (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 

  
 4 








 
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. 
 (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 

  
 5 








 
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.
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 

  
 6 








 
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 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 

  
 7 








 
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. 
 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. 

  
 8 








 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 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 

  
 9 








 
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. 

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. 

  
 10 








 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. 

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 

  
 11 








 
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.” 

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; provided, further, however, that such one
hundred eighty (180) day period may be extended for an additional period, not to exceed twenty (20) days, upon the request of the Company or the 

  
 12 








 
underwriter to accommodate regulatory restrictions on (i) the publication or other distribution of research reports and (ii) analyst recommendations and opinions, including but not
limited to, the restrictions contained in NASD Rule 2711(f)(4) or NYSE Rule 472(f)(4), or any successor provisions or amendments thereto). The foregoing limitation shall not apply to shares registered in the public offering under the Securities Act.
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 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. 

  
 13 








 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.

 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

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 that 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,
