 Exhibit 10.3 

FIRST ADVANTAGE CORPORATION 

2021 EMPLOYEE STOCK PURCHASE PLAN 

1. Purpose. The purpose of the Plan is to provide Eligible Employees (as defined below) with an opportunity to purchase Common
Stock through accumulated Contributions. The Company intends for the Plan to have two components: a Code Section 423 Component (“423 Component”) and a non-Code Section 423
Component (“Non-423 Component”). The Company intends to have the 423 Component of the Plan qualify as an “employee stock purchase plan” under Section 423 of the Code. The
provisions of the 423 Component, accordingly, will be construed so as to extend and limit Plan participation in a uniform and nondiscriminatory basis consistent with the requirements of Section 423 of the Code. In addition, the Plan authorizes
the grant of an option to purchase shares of Common Stock under the Non-423 Component that does not qualify as an “employee stock purchase plan” under Section 423 of the Code; such an option
will be granted pursuant to rules, procedures or sub-plans adopted by the Administrator designed to achieve tax, securities laws or other objectives for Eligible Employees and the Company. Except as otherwise
provided herein, the Non-423 Component will operate and be administered in the same manner as the 423 Component. 

2. Definitions.

“423 Component” is defined in Section 1 of the Plan. 
 (b) “Administrator” means the

Plan, the employment relationship will be treated as continuing intact while the individual is on sick leave or other leave of absence that the Employer approves or is legally protected under applicable laws. Where the period of leave exceeds three
(3) months and the individual’s right to reemployment is not guaranteed either by statute or by contract, the employment relationship will be deemed to have terminated three (3) months and one (1) day following the commencement
of such leave. The Administrator, in its discretion, from time to time may, prior to an Enrollment Date for all options to be granted on such Enrollment Date in an Offering, determine (for each Offering under the 423 Component, on a uniform and

Section 1.423-2(e)(2)(ii). Such exclusions may be applied with respect to an Offering under the Non-423 Component without regard to the limitations of Treasury

permitted by U.S. Treasury Regulation Section 1.423-2(a)(1), the terms of each Offering need not be identical; provided, that the terms of the Plan and an Offering together satisfy U.S. Treasury

participation in the Plan or an Offering if the participation of such Eligible Employees is prohibited under the laws of the applicable jurisdiction or if complying with the laws of the applicable jurisdiction would cause the Plan or an Offering to
violate Section 423 of the Code. In the case of the Non-423 Component, an Eligible Employee may be excluded from participation in the Plan or an Offering if the Administrator has determined that
participation of such Eligible Employee is not advisable or practicable. 

  
 4 

 (d) Limitations. Any provisions of the Plan to the contrary notwithstanding, no
Eligible Employee will be granted an option under the Plan (i) to the extent that, immediately after the grant, such Eligible Employee (or any other Person whose stock would be attributed to such Eligible Employee pursuant to
Section 424(d) of the Code) would own capital stock of the Company or any Parent or Subsidiary of the Company and/or hold outstanding options to purchase such stock possessing five percent (5%) or more of the total combined voting power or
value of all classes of the capital stock of the Company or of any Parent or Subsidiary of the Company, or (ii) to the extent that his or her rights to purchase stock under all employee stock purchase plans (as defined in Section 423 of

a new Offering Period shall commence on the first Trading Day on or following January 1 and July 1 of each calendar year and end on or following the last Trading Day on or immediately preceding June 30 and December 31,
respectively, approximately six (6) months later. 
 (d) Additional Offering Periods. At the discretion of the Administrator,
additional Offering Periods may be conducted under the Plan. Such additional Offering Periods may, but need not, qualify under Section 423 of the Code. The Administrator shall determine the commencement and duration of each additional Offering
Period, and additional Offering Periods may be consecutive or overlapping. The other terms and conditions of each additional Offering Period shall be those set forth in the Plan document, with such changes or additional features as the Administrator
determines necessary to comply with Section 423 of the Code (or any successor rule or provision or any other Applicable Law, regulation or stock exchange rule). The Administrator shall have the power to change the duration of Offering Periods
(including the commencement dates thereof) with respect to future Offerings without stockholder approval. 
 (e) Offering Period
Limit. No Offering Period may last more than twenty-seven (27) months. 
 (f) Applicable Offering Period. For purposes of
calculating the Purchase Price, the applicable Offering Period shall be determined as follows: Once a Participant is enrolled in the Plan for an Offering Period, such Offering Period shall continue to apply to him or her until the earliest of
(x) the end of such Offering Period, or (y) the end of his or her participation under Section 10 of the Plan. 
 5.
Participation. 
 (a) First Offering Period. An Eligible Employee will be entitled to continue to participate in the first
Offering Period pursuant to Section 3(a) of the Plan only if such individual submits a subscription agreement authorizing Contributions in a form determined by the Administrator (which may be similar to the form attached hereto as Exhibit
B) to the Company’s designated third-party broker/plan administrator (i) no earlier than the effective date of the Form S-8 registration statement that registers the offer and sale of Common
Stock under the Plan and (ii) no later than ten (10) business days following the effective date of such S-8 registration statement or such other period of time as the Administrator may determine (the
“Enrollment Window”). 

  
 5 

 (b) Subsequent Offering Periods. Once an Eligible Employee begins participation in an
Offering Period, then such Eligible Employee will automatically participate in each subsequent Offering Period unless the Eligible Employee withdraws or is deemed to withdraw from this Plan or terminates further participation in an Offering Period
as set forth in Section 10 below. An Eligible Employee who is continuing participation pursuant to the immediately preceding sentence is not required to file any additional subscription agreement in order to continue participation in this Plan;
during each subsequent Offering Period an Eligible Employee who is not continuing participation pursuant to the immediately preceding sentence is required to file a subscription agreement prior to the commencement of the Offering Period (or such
earlier date as the Administrator may determine) to which such agreement relates in order to participate in such Offering Period. 
 6.
Contributions. 
 (a) At the time a Participant enrolls in the Plan pursuant to Section 5 of the Plan, he or she will elect to have
Contributions (in the form of payroll deductions or otherwise, to the extent permitted by the Administrator) made on each pay day during the Offering Period in an amount not exceeding fifteen percent (15%) of the Compensation, which he or she
receives on each pay day during the Offering Period (for illustrative purposes, should a pay day occur on an Exercise Date, a Participant will have any payroll deductions made on such day applied to his or her account under the then-current Purchase
Period or Offering Period). The Administrator, in its sole discretion, may permit all Participants in a specified Offering to contribute amounts to the Plan through payment by cash, check or other means set forth in the subscription agreement prior
to each Exercise Date of each Purchase Period. A Participant’s subscription agreement will remain in effect for successive Offering Periods unless terminated as provided in Section 10 hereof. 

(b) In the event Contributions are made in the form of payroll deductions, such payroll deductions for a Participant will commence on the
first day of the payroll cycle following the Enrollment Date and will end on the last pay day prior to the Exercise Date of such Offering Period to which such authorization is applicable, unless sooner terminated by the Participant as provided in
Section 10 hereof or suspended by the Participant as provided in Section 6(d) hereof; provided, that for the first Offering Period, payroll deductions will commence on the first day of the payroll cycle following the end of the
Enrollment Window. 
 (c) All Contributions made for a Participant will be credited to his or her account under the Plan, and Contributions
will be made in whole percentages of Compensation only. A Participant may not make any additional payments into such account. 
 (d) A
Participant may discontinue his or her participation in the Plan as provided in Section 10 of the Plan. If permitted by the Administrator, as determined in its sole discretion, a Participant may, on a single occasion, either reduce his or her
rate of contribution during, or suspend his or her contributions for the remainder of, an on-going Offering Period by filing with the Company’s designated third-party broker/plan administrator a new
authorization for payroll deductions, with the new rate of contribution, or suspension of contributions, to become effective as soon as reasonably practicable and continuing for the remainder of the Offering Period. If a Participant suspends his or
her contributions at any time during an Offering Period, such Participant’s cumulative contributions prior to such suspension shall be used to purchase shares on the next occurring Exercise Date unless such Participant discontinues his or her
participation in the Plan as provided in Section 10 of the Plan prior to such Exercise Date. 

  
 6 

 (e) To the extent necessary to comply with Section 423(b)(8) of the Code and
Section 3(d) hereof, a Participant’s Contributions may be decreased to zero percent (0%) at any time during a Purchase Period. Subject to Section 423(b)(8) of the Code and Section 3(d) hereof, Contributions will recommence at the
rate originally elected by the Participant effective as of the beginning of the first Purchase Period scheduled to end in the following calendar year, unless terminated by the Participant as provided in Section 10 of the Plan. 

(f) Notwithstanding any provisions to the contrary in the Plan, the Administrator may allow Eligible Employees to participate in the Plan via
cash contributions instead of payroll deductions if (i) payroll deductions are not permitted under applicable local law, (ii) the Administrator determines that cash contributions are permissible under Section 423 of the Code or
(iii) for Participants participating in the Non-423 Component. 
 (g) At the time the option is
exercised, in whole or in part, or at the time some or all of the Common Stock issued under the Plan is disposed of (or any other time that a taxable event related to the Plan occurs), the Participant must make adequate provision for the
Company’s or the Employer’s federal, state, local or any other tax liability payable to any authority including taxes imposed by jurisdictions outside of the U.S., national insurance, social security or other tax withholding obligations,
if any, which arise upon the exercise of the option or the disposition of the Common Stock (or any other time that a taxable event related to the Plan occurs). At any time, the Company or the Employer may, but will not be obligated to, withhold from
the Participant’s compensation the amount necessary for the Company or the Employer to meet applicable withholding obligations, including any withholding required to make available to the Company or the Employer any tax deductions or benefits
attributable to sale or early disposition of Common Stock by the Eligible Employee. In addition, the Company or the Employer may, but will not be obligated to, withhold from the proceeds of the sale of Common Stock or any other method of withholding
the Company or the Employer deems appropriate to the extent permitted by U.S. Treasury Regulation Section 1.423-2(f). 

7. Grant of Option. On the Enrollment Date of an applicable Offering Period, each Eligible Employee participating in such
Offering Period will be granted an option to purchase on each Exercise Date during such Offering Period (at the applicable Purchase Price) up to a number of shares of Common Stock determined by dividing such Eligible Employee’s Contributions
accumulated prior to such Exercise Date and retained in the Eligible Employee’s account as of the Exercise Date by the applicable Purchase Price; provided, that in no event will an Eligible Employee be permitted to purchase during each
Purchase Period more than 1,500 shares of Common Stock and, during any one year period, more than 3,000 shares of Common Stock, subject, in each case to any adjustment pursuant to Section 19 of the Plan; provided, further, that
such purchase will be subject to the limitations set forth in Sections 3(d) and 13 of the Plan. The Eligible Employee may accept the grant of such option (i) with respect to the first Offering Period by submitting a properly completed
subscription agreement in accordance with the requirements of Section 5 of the Plan on or before the last day of the Enrollment Window, and (ii) with respect to any subsequent Offering Period under the Plan, by continuing to (or electing
to, as applicable) participate in the Plan in accordance with the requirements of Section 5 of the Plan. The Administrator may, for future Offering Periods, increase or decrease, in its absolute discretion, the maximum number of shares of
Common Stock that an Eligible Employee may purchase during each Purchase Period of an Offering Period or during any one-year period. Exercise of the option will occur as provided in Section 8, unless the
Participant has withdrawn pursuant to Section 10 of the Plan. To the extent not otherwise exercised in full, the option will expire on the last day of the Offering Period. 

  
 7 

 8. Exercise of Option. 

(a) Unless a Participant withdraws from the Plan as provided in Section 10 of the Plan, his or her option for the purchase of shares of
Common Stock will be exercised automatically on the Exercise Date, and the maximum number of full shares subject to the option will be purchased for such Participant at the applicable Purchase Price with the accumulated Contributions from his or her
account. No fractional shares of Common Stock will be purchased; any Contributions accumulated in a Participant’s account, which are not sufficient to purchase a full share will be retained in the Participant’s account for the subsequent
Purchase Period or Offering Period, subject to earlier withdrawal by the Participant. Any other funds left over in a Participant’s account after the Exercise Date will also be retained in the Participant’s account for the subsequent
Purchase Period or Offering Period, subject to earlier withdrawal by the Participant. During a Participant’s lifetime, a Participant’s option to purchase shares hereunder is exercisable only by him or her. 

(b) If the Administrator determines that, on a given Exercise Date, the number of shares of Common Stock with respect to which options are to
be exercised may exceed (i) the number of shares of Common Stock that were available for sale under the Plan on the Enrollment Date of the applicable Offering Period, or (ii) the number of shares of Common Stock available for sale under
the Plan on such Exercise Date, the Administrator may in its sole discretion (x) provide that the Company will make a pro rata allocation of the shares of Common Stock available for purchase on such Enrollment Date or Exercise Date, as
applicable, in as uniform a manner as will be practicable and as it will determine in its sole discretion to be equitable among all Participants exercising options to purchase Common Stock on such Exercise Date, and continue all Offering Periods
then in effect or (y) provide that the Company will make a pro rata allocation of the shares available for purchase on such Enrollment Date or Exercise Date, as applicable, in as uniform a manner as will be practicable and as it will determine
in its sole discretion to be equitable among all participants exercising options to purchase Common Stock on such Exercise Date, and terminate any or all Offering Periods then in effect pursuant to Section 20 of the Plan. The Company may make a
pro rata allocation of the shares available on the Enrollment Date of any applicable Offering Period pursuant to the preceding sentence, notwithstanding any authorization of additional shares for issuance under the Plan by the Company’s
stockholders subsequent to such Enrollment Date. 
 9. Delivery. As soon as reasonably practicable after each Exercise Date on
which a purchase of shares of Common Stock occurs, the Company will arrange the delivery to each Participant of the shares purchased upon exercise of his or her option in a form determined by the Administrator (in its sole discretion) and pursuant
to rules established by the Administrator. The Company may permit or require that shares be deposited directly with a broker designated by the Company or to a designated agent of the Company, and the Company may utilize electronic or automated
methods of share transfer. The Company may require that shares be retained with such broker or agent for a designated period of time and/or may establish other procedures to permit tracking of disqualifying dispositions of such shares. No
Participant will have any voting, dividend, or other stockholder rights with respect to shares of Common Stock subject to any option granted under the Plan until such shares have been purchased and delivered to the Participant as provided in this
Section 9. 
 10. Withdrawal. 

(a) A Participant may withdraw all but not less than all the Contributions credited to his or her account and not yet used to exercise his or
her option under the Plan at any time prior to the last thirty (30) days of the applicable Offering Period by (i) submitting to the Company’s stock administration office (or its designee) a written notice of withdrawal in the form
determined by the Administrator for such purpose (which may be similar to the form attached hereto as Exhibit C), or (ii) following an electronic or other withdrawal procedure determined by the Administrator; provided, that a
Participant may not withdraw 

  
 8 

 
during any blackout period applicable to such Participant. All of the Participant’s Contributions credited to his or her account will be paid to such Participant promptly and as soon as
administratively feasible after receipt of notice of withdrawal by the Company’s stock administration office (or its designee) and such Participant’s option for the Offering Period will be automatically terminated, and no further
Contributions for the purchase of shares will be made for such Offering Period. If a Participant withdraws from an Offering Period, Contributions will not resume at the beginning of the succeeding Offering Period, unless the Participant re-enrolls in the Plan by submitting a subscription agreement to the Company’s designated third-party broker/plan administrator prior to the commencement of such succeeding Offering Period. 

(b) A Participant’s withdrawal from an Offering Period will not have any effect upon his or her eligibility to participate in any similar
plan that may hereafter be adopted by the Company or in succeeding Offering Periods that commence after the termination of the Offering Period from which the Participant withdraws. 

11. Termination of Employment. Upon a Participant’s ceasing to be an Eligible Employee, for any reason, he or she will be
deemed to have elected to withdraw from the Plan and the Contributions credited to such Participant’s account during the Offering Period but not yet used to purchase shares of Common Stock under the Plan will be returned to such Participant or,
in the case of his or her death, to the Person or Persons entitled thereto under Section 15 of the Plan, and such Participant’s option will be automatically terminated. Unless determined otherwise by the Administrator in a manner that,
with respect to an Offering under the 423 Component, is permitted by, and compliant with, Section 423 of the Code, a Participant whose employment transfers between entities through a termination with an immediate rehire (with no break in
service) by the Company or a Designated Company shall not be treated as terminated under the Plan; provided, however, that no Participant shall be deemed to switch from an Offering under the
Non-423 Component to an Offering under the 423 Component or vice versa unless (and then only to the extent) such switch would not cause the 423 Component or any Option thereunder to fail to comply with
Section 423 of the Code. 
 12. Interest. No interest will accrue on the Contributions of a participant in the Plan,
except as may be required by Applicable Law, as determined by the Company, and if so required by the laws of a particular jurisdiction, shall, with respect to Offerings under the 423 Component, apply to all Participants in the relevant Offering,
except to the extent otherwise permitted by U.S. Treasury Regulation Section 1.423-2(f). 

13. Stock. 
 (a) Subject
to adjustment upon changes in capitalization of the Company as provided in Section 19 hereof, the aggregate number of shares of Common Stock available for the issuance of shares pursuant to the Plan shall be no more than 1,525,000 shares, which
number shall be automatically increased on the first day of each fiscal year following the fiscal year in which the Effective Date falls in an amount equal to the lesser of (x) 0.75% of the total number of all classes of the Company’s common
stock outstanding on the last day of the immediately preceding fiscal year and (y) a lower number of shares of Common Stock as determined by the Board. Notwithstanding anything in this Section 13(a) to the contrary, the number of shares of
Common Stock that may be issued or transferred pursuant to the rights granted under the 423 Component of the Plan shall not exceed an aggregate of 12,825,000 shares, subject to Section 19. 

(b) Until the shares of Common Stock are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized
transfer agent of the Company), a Participant will only have the rights of an unsecured creditor with respect to such shares, and no right to vote or receive dividends or any other rights as a stockholder will exist with respect to such shares. 

  
 9 

 (c) Shares of Common Stock to be delivered to a Participant under the Plan will be
registered in the name of the Participant or in the name of the Participant and his or her spouse. 
 14. Administration. The
Plan will be administered by the Board or a Committee appointed by the Board, which Committee will be constituted to comply with Applicable Laws. To the extent not prohibited by Applicable Laws, the Committee may, from time to time, delegate some or
all of its authority under the Plan to the Administrator as it deems necessary, appropriate or advisable under conditions or limitations that it may set at or after the time of the delegation. For purposes of the Plan, all references to the
Committee will be deemed to refer to the Administrator to whom the Committee delegates authority pursuant to this Section 14. The Administrator will have full and exclusive discretionary authority to construe, interpret and apply the terms of
the Plan, to designate separate Offerings under the Plan, to designate Subsidiaries and Affiliates as participating in the 423 Component or Non-423 Component, to determine eligibility, to adjudicate all
disputed claims filed under the Plan and to establish such procedures that it deems necessary for the administration of the Plan (including, without limitation, to adopt such procedures and sub-plans as are
necessary or appropriate to permit the participation in the Plan by employees who are foreign nationals or employed outside the U.S., the terms of which sub-plans may take precedence over other provisions of
the Plan, with the exception of Section 13(a) hereof, but unless otherwise superseded by the terms of such sub-plan, the provisions of the Plan shall govern the operation of such sub-plan). Unless otherwise determined by the Administrator, the employees eligible to participate in each sub-plan will participate in a separate Offering and will be in the Non-423 Component, unless such designation would cause the 423 Component to violate the requirements of Section 423 of the Code. Without limiting the generality of the foregoing, the Administrator is
specifically authorized to adopt rules and procedures regarding eligibility to participate, the definition of Compensation, handling of Contributions, making of Contributions to the Plan (including, without limitation, in forms other than payroll
deductions), establishment of bank or trust accounts to hold Contributions, payment of interest, conversion of local currency, obligations to pay payroll tax, determination of beneficiary designation requirements, withholding procedures and handling
of stock certificates that vary with applicable local requirements. The Administrator also is authorized to determine that, to the extent permitted by U.S. Treasury Regulation Section 1.423-2(f), the
terms of an option granted under the Plan or an Offering to citizens or residents of a non-U.S. jurisdiction will be less favorable than the terms of options granted under the Plan or the same Offering to
employees resident solely in the U.S. Every finding, decision and determination made by the Administrator will, to the full extent permitted by law, be final and binding upon all parties. 

15. Designation of Beneficiary. 

(a) If permitted by the Administrator, a Participant may file a designation of a beneficiary who is to receive any shares of Common Stock and
cash, if any, from the Participant’s account under the Plan in the event of such Participant’s death subsequent to an Exercise Date on which the option is exercised but prior to delivery to such Participant of such shares and cash. In
addition, if permitted by the Administrator, a Participant may file a designation of a beneficiary who is to receive any cash from the Participant’s account under the Plan in the event of such Participant’s death prior to exercise of the
option. If a Participant is married and the designated beneficiary is not the spouse, spousal consent will be required for such designation to be effective. 

(b) Such designation of beneficiary may be changed by the Participant at any time by notice to the Company’s stock administration office
(or its designee) in a form determined by the Administrator. In the event of the death of a Participant and in the absence of a beneficiary validly designated under the Plan who is living at the time of such Participant’s death, the Company
will deliver such shares and/or cash to the executor or administrator of the estate of the Participant, or if no such executor or administrator has been appointed (to the knowledge of the Company), the Company, in its discretion, may deliver such
shares and/or cash to the spouse or to any one or more dependents or relatives of the Participant, or if no spouse, dependent or relative is known to the Company, then to such other Person as the Company may designate. 

  
 10 

 (c) All beneficiary designations will be in such form and manner as the Administrator may
designate from time to time. Notwithstanding Sections 15(a) and (b) above, the Company and/or the Administrator may decide not to permit such designations by Participants in non-U.S. jurisdictions to the
extent permitted by U.S. Treasury Regulation Section 1.423-2(f). 
 16.
Transferability. Neither Contributions credited to a Participant’s account nor any rights with regard to the exercise of an option or to receive shares of Common Stock under the Plan may be assigned, transferred, pledged or otherwise
disposed of in any way (other than by will, the laws of descent and distribution or as provided in Section 15 hereof) by the Participant. Any such attempt at assignment, transfer, pledge or other disposition will be without effect, except that
the Company may treat such act as an election to withdraw funds from an Offering Period in accordance with Section 10 hereof. 

17. Use of Funds. The Company may use all Contributions received or held by it under the Plan for any corporate purpose, and the
Company will not be obligated to segregate such Contributions except under Offerings or for Participants in the Non-423 Component for which Applicable Laws require that Contributions to the Plan by
Participants be segregated from the Company’s general corporate funds and/or deposited with an independent third party. 
 18.
Reports. Individual accounts will be maintained for each Participant in the Plan. Statements of account will be given to participating Eligible Employees at least annually, which statements will set forth the amounts of Contributions, the
Purchase Price, the number of shares of Common Stock purchased and the remaining cash balance, if any. 
 19. Adjustments, Dissolution,
Liquidation, Merger or Change in Control. 
 (a) Adjustments. In the event that any subdivision or consolidation of outstanding
shares of Common Stock, declaration of a dividend payable in shares of Common Stock or other stock split, other recapitalization or capital reorganization of the Company, any consolidation or merger of the Company with another corporation or entity,
the adoption by the Company of any plan of exchange affecting the Common Stock or any distribution to holders of Common Stock of securities or property (other than normal cash dividends or dividends payable in Common Stock), the Committee, in order
to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan, will, in such manner as it may deem equitable, adjust the number and class of Common Stock that may be delivered under the Plan,
the Purchase Price per share and the number of shares of Common Stock covered by each option under the Plan that has not yet been exercised, and the numerical limits of Sections 7 and 13 of the Plan. For the avoidance of doubt, the Committee may not
delegate its authority to make adjustments pursuant to this Section 19(a). 
 (b) Dissolution or Liquidation. In the event of
the proposed dissolution or liquidation of the Company, any Offering Period then in progress will be shortened by setting a New Exercise Date, and will terminate immediately prior to the consummation of such proposed dissolution or liquidation,
unless provided otherwise by the Administrator. The New Exercise Date will be before the date of the Company’s proposed dissolution or liquidation. The Company’s stock administration office (or its designee) will notify each Participant in
writing or electronically, prior to the New Exercise Date, that the Exercise Date for the Participant’s option has been changed to the New Exercise Date and that the Participant’s option will be exercised automatically on the New Exercise
Date, unless prior to such date the Participant has withdrawn from the Offering Period as provided in Section 10 hereof. 

  
 11 

 (c) Merger or Change in Control. In the event of a merger or Change in Control, each
outstanding option will be assumed or an equivalent option substituted by the successor corporation or a Parent or Subsidiary of the successor corporation. In the event that the successor corporation refuses to assume or substitute for the option,
the Offering Period with respect to which such option relates will be shortened by setting a New Exercise Date on which such Offering Period shall end. The New Exercise Date will occur before the date of the Company’s proposed merger or Change
in Control. The Company’s stock administration office (or its designee) will notify each Participant in writing or electronically prior to the New Exercise Date, that the Exercise Date for the Participant’s option has been changed to the
New Exercise Date and that the Participant’s option will be exercised automatically on the New Exercise Date, unless prior to such date the Participant has withdrawn from the Offering Period as provided in Section 10 hereof. 

20. Amendment or Termination. 

(a) The Board or the Administrator, in its sole discretion, may amend, suspend, or terminate the Plan, or any part thereof, at any time and
for any reason. If the Plan is terminated, the Board or the Administrator, in its discretion, may elect to terminate all outstanding Offering Periods either immediately or upon completion of the purchase of shares of Common Stock on the next
Exercise Date (which may be sooner than originally scheduled, if determined by the Administrator in its discretion), or may elect to permit Offering Periods to expire in accordance with their terms (and subject to any adjustment pursuant to
Section 19 hereof). If the Offering Periods are terminated prior to expiration, all amounts then credited to Participants’ accounts that have not been used to purchase shares of Common Stock will be returned to the Participants (without
interest thereon, except as otherwise required under Applicable Laws, as further set forth in Section 12 hereof) as soon as administratively practicable. 

(b) Without stockholder consent and without limiting Section 20(a) hereof, the Administrator will be entitled to change the Offering
Periods or Purchase Periods, designate separate Offerings, limit the frequency and/or number of changes in the amount withheld during an Offering Period, establish the exchange ratio applicable to amounts withheld in a currency other than U.S.
dollars, permit Contributions in excess of the amount designated by a Participant in order to adjust for delays or mistakes in the Company’s processing of properly completed Contribution elections, establish reasonable waiting and adjustment
periods and/or accounting and crediting procedures to ensure that amounts applied toward the purchase of Common Stock for each Participant properly correspond with Contribution amounts, and establish such other limitations or procedures as the
Administrator determines in its sole discretion advisable that are consistent with the Plan. 
 (c) In the event the Administrator
determines that the ongoing operation of the Plan may result in unfavorable financial accounting consequences, the Administrator may, in its discretion and, to the extent necessary or desirable, modify, amend or terminate the Plan to reduce or
eliminate such accounting consequence including, but not limited to: 
 (i) amending the Plan to conform with the safe harbor definition
under the Financial Accounting Standards Board Accounting Standards Codification Topic 718 (or any successor thereto), including with respect to an Offering Period underway at the time; 

(ii) altering the Purchase Price for any Offering Period or Purchase Period including an Offering Period or Purchase Period underway at the
time of the change in Purchase Price; 
 (iii) shortening any Offering Period or Purchase Period by setting a New Exercise Date, including
an Offering Period or Purchase Period underway at the time of the Administrator action; 

  
 12 

 (iv) reducing the maximum percentage of Compensation a Participant may elect to set aside
as Contributions; and 
 (v) reducing the maximum number of shares of Common Stock a Participant may purchase during any Offering Period or
Purchase Period. 
 Such modifications or amendments will not require stockholder approval or the consent of any Plan Participants. 

21. Notices. All notices or other communications by a Participant to the Company under or in connection with the Plan will be
deemed to have been duly given when received by the Company’s stock administration office (or its designee) in the form and manner specified by the Company’s stock administration office (or its designee)at the location, or by the Person,
designated by the Company’s stock administration office (or its designee) for the receipt thereof. 
 22. Conditions Upon Issuance
of Shares. 
 (a) Shares of Common Stock will not be issued with respect to an option unless the exercise of such option and the
issuance and delivery of such shares pursuant thereto will comply with all applicable provisions of law, domestic or foreign, including, without limitation, the Securities Act of 1933, as amended, the Exchange Act, the rules and regulations
promulgated thereunder, and the requirements of any stock exchange upon which the shares may then be listed, and will be further subject to the approval of counsel for the Company with respect to such compliance. 

(b) As a condition to the exercise of an option, the Company may require the Person exercising such option to represent and warrant at the
time of any such exercise that the shares are being purchased only for investment and without any present intention to sell or distribute such shares if, in the opinion of counsel for the Company, such a representation is required by any of the
aforementioned applicable provisions of law. 
 23. Data Protection. By participating in the Plan or accepting any rights
granted under it, each Participant consents to the collection and processing of personal data relating to the Participant so that the Company and its Affiliates can fulfill their obligations and exercise their rights under the Plan and generally
administer and manage the Plan. This data will include, but may not be limited to, data about participation in the Plan and shares offered or received, purchased, or sold under the Plan from time to time and other appropriate financial and other
data about the Participant and the Participant’s participation in the Plan. 
 24. Code Section 409A.
The 423 Component of the Plan is exempt from the application of Code Section 409A and any ambiguities herein will be interpreted to so be exempt from Code Section 409A. In furtherance of the foregoing and notwithstanding any provision in
the Plan to the contrary, if the Administrator determines that an option granted under the Plan may be subject to Code Section 409A or that any provision in the Plan would cause an option under the Plan to be subject to Code Section 409A,
the Administrator may amend the terms of the Plan and/or of an outstanding option granted under the Plan, or take such other action the Administrator determines is necessary or appropriate, in each case, without the Participant’s consent, to
exempt any outstanding option or future option that may be granted under the Plan from or to allow any such options to comply with Code Section 409A, but only to the extent any such amendments or action by the Administrator would not violate
Code Section 409A. Notwithstanding the foregoing, the Company shall have no liability to a Participant or any other party if the option to purchase Common Stock under the Plan that is intended to be exempt from or compliant with Code
Section 409A is not so exempt or compliant or for any action taken by the Administrator with respect thereto. The Company makes no representation that the option to purchase Common Stock under the Plan is compliant with Code Section 409A.

  
 13 

 25. Term of Plan. The Plan will become effective upon the earlier to occur of
its adoption by the Board or its approval by the stockholders of the Company (the “Effective Date”). It will continue in effect for a term of ten (10) years, unless sooner terminated under Section 20 of the Plan.

 26. Stockholder Approval. The Plan will be subject to approval by the stockholders of the Company within twelve
(12) months before or after the date the Plan is adopted by the Board. Such stockholder approval will be obtained in the manner and to the degree required under Applicable Laws. 

27. Governing Law. The Plan shall be governed by, and construed in accordance with, the laws of the State of Delaware (except
its choice-of-law provisions). 
 28. No Right to
Employment. Participation in the Plan by a Participant shall not be construed as giving a Participant the right to be retained as an employee of the Company or a Subsidiary or Affiliate, as applicable. Furthermore, the Employer may dismiss a
Participant from employment at any time, free from any liability or any claim under the Plan. 
 29. Severability. If any
provision of the Plan is or becomes or is deemed to be invalid, illegal, or unenforceable for any reason in any jurisdiction or as to any Participant, such invalidity, illegality or unenforceability shall not affect the remaining parts of the Plan,
and the Plan shall be construed and enforced as to such jurisdiction or Participant as if the invalid, illegal or unenforceable provision had not been included. 

30. Compliance with Applicable Laws. The terms of the Plan are intended to comply with all Applicable Laws and will be construed
accordingly. 
 31. Jurisdiction; Waiver of Jury Trial. The Plan shall be governed by and construed in accordance with the
internal laws of the State of Delaware applicable to contracts made and performed wholly within the State of Delaware, without giving effect to the conflict of laws provisions thereof. EACH PARTICIPANT IRREVOCABLY WAIVES ALL RIGHT TO A TRIAL BY JURY
IN ANY SUIT, ACTION, OR OTHER PROCEEDING INSTITUTED BY OR AGAINST SUCH PARTICIPANT IN RESPECT OF THE PARTICIPANT’S RIGHTS OR OBLIGATIONS HEREUNDER.

(2) years after the date of this Agreement or (ii) one hundred eighty (180) days after the effective date of the 

  
 4 

 
registration statement for the IPO, the Company receives a request from Holders of a majority of the Registrable Securities then outstanding that the Company file a Form S-1 registration statement with respect to at least a majority of the Registrable Securities then outstanding (or a lesser percent if the anticipated aggregate offering price, net of Selling Expenses, would exceed
$15 million), then the Company shall (x) within ten (10) days after the date such request is given, give notice thereof (the “Demand Notice”) to all Holders other than the Initiating Holders; and
(y) as soon as practicable, and in any event within sixty (60) days after the date such request is given by the Initiating Holders, file a Form S-1 registration statement under the Securities Act covering all Registrable
Securities that the Initiating Holders requested to be registered and any additional Registrable Securities requested to be included in such registration by any other Holders, as specified by notice given by each such Holder to the Company within
twenty (20) days of the date the Demand Notice is given, and in each case, subject to the limitations of Subsections 2.1(c) and 2.3. 

(b)    Form S-3 Demand. If at any time when it is eligible to use a Form S-3 registration statement, the Company receives a request from Holders of at least a majority of the Registrable Securities then outstanding that the Company file a Form S-3
registration statement with respect to outstanding Registrable Securities of such Holders having an anticipated aggregate offering price, net of Selling Expenses, of at least $5 million, then the Company shall (i) within ten
(10) days after the date such request is given, give a Demand Notice to all Holders other than the Initiating Holders; and (ii) as soon as practicable, and in any event within forty-five (45) days after the date
such request is given by the Initiating Holders, file a Form S-3 registration statement under the Securities Act covering all Registrable Securities requested to be included in such registration by any other Holders, as specified by notice given by
each such Holder to the Company within twenty (20) days of the date the Demand Notice is given, and in each case, subject to the limitations of Subsections 2.1(c) and 2.3. 

(c)    Notwithstanding the foregoing obligations, if the Company furnishes to Holders requesting a registration pursuant
to this Subsection 2.1 a certificate signed by the Company’s chief executive officer stating that in the good faith judgment of the Board of Directors it would be materially detrimental to the Company and its stockholders for such
registration statement to either become effective or remain effective for as long as such registration statement otherwise would be required to remain effective, because such action would (i) materially interfere with a significant
acquisition, corporate reorganization, or other similar transaction involving the Company; (ii) require premature disclosure of material information that the Company has a bona fide business purpose for preserving as confidential; or
(iii) render the Company unable to comply with requirements under the Securities Act or Exchange Act, then the Company shall have the right to defer taking action with respect to such filing, and any time periods with respect to filing
or effectiveness thereof shall be tolled correspondingly, for a period of not more than one hundred twenty (120) days after the request of the Initiating Holders is given; provided, however, that the Company may not invoke
this right more than once in any twelve (12) month period; and provided further that the Company shall not register any securities for its own account or that of any other stockholder during such one hundred twenty
(120) day period other than pursuant to a registration relating to the sale or grant of securities to employees of the Company or a subsidiary pursuant to a stock option, stock purchase, equity incentive or similar plan; a registration
on any form that does not include substantially the same information as would be required to be included in a registration statement covering the sale of the Registrable Securities; or a registration in which the only Common Stock being registered
is Common Stock issuable upon conversion of debt securities that are also being registered. 

  
 5 

 (d)    The Company shall not be obligated to effect, or to take any
action to effect, any registration pursuant to Subsection 2.1(a) (i) during the period that is sixty (60) days before the Company’s good faith estimate of the date of filing of, and ending on a date that is
one hundred eighty (180) days after the effective date of, a Company-initiated registration, provided that the Company is actively employing in good faith commercially reasonable efforts to cause such registration statement to
become effective; (ii) after the Company has effected one registration pursuant to Subsection 2.1(a); or (iii) if the Initiating Holders propose to dispose of shares of Registrable Securities that may be
immediately registered on Form S-3 pursuant to a request made pursuant to Subsection 2.1(b). The Company shall not be obligated to effect, or to take any action to effect, any registration pursuant to Subsection 2.1(b)
(i) during the period that is thirty (30) days before the Company’s good faith estimate of the date of filing of, and ending on a date that is ninety (90) days after the effective date of, a Company-initiated
registration, provided that the Company is actively employing in good faith commercially reasonable efforts to cause such registration statement to become effective; or (ii) if the Company has effected two registrations pursuant to
Subsection 2.1(b) within the twelve (12) month period immediately preceding the date of such request. A registration shall not be counted as “effected” for purposes of this Subsection 2.1(d) until such time as
the applicable registration statement has been declared effective by the SEC, unless the Initiating Holders withdraw their request for such registration, elect not to pay the registration expenses therefor, and forfeit their right to one demand
registration statement pursuant to Subsection 2.6, in which case such withdrawn registration statement shall be counted as “effected” for purposes of this Subsection 2.1(d); provided, that if such withdrawal
is during a period the Company has deferred taking action pursuant to Subsection 2.1(c), then the Initiating Holders may withdraw their request for registration and such registration will not be counted as “effected” for
purposes of this Subsection 2.1(d). 
 2.2    Company Registration. If the Company proposes to
register (including, for this purpose, a registration effected by the Company for stockholders other than the Holders) any of its Common Stock under the Securities Act in connection with the public offering of such securities solely for cash (other
than in an Excluded Registration), the Company shall, at such time, promptly give each Holder notice of such registration. Upon the request of each Holder given within twenty (20) days after such notice is given by the Company, the Company
shall, subject to the provisions of Subsection 2.3, cause to be registered all of the Registrable Securities that each such Holder has requested to be included in such registration. The Company shall have the right to terminate or
withdraw any registration initiated by it under this Subsection 2.2 before the effective date of such registration, whether or not any Holder has elected to include Registrable Securities in such registration. The expenses (other than
Selling Expenses) of such withdrawn registration shall be borne by the Company in accordance with Subsection 2.6. 

2.3    Underwriting Requirements. 

(a)    If, pursuant to Subsection 2.1, the Initiating Holders intend to distribute the Registrable Securities
covered by their request by means of an underwriting, they shall so advise the Company as a part of their request made pursuant to Subsection 2.1, and the Company shall include such information in the Demand Notice. The underwriter(s)
will be 

  
 6 

 
selected by the Company and shall be reasonably acceptable to a majority in interest of the Initiating Holders. In such event, the right of any Holder to include such Holder’s Registrable
Securities in such registration shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein. All Holders proposing
to distribute their securities through such underwriting shall (together with the Company as provided in Subsection 2.4(e)) enter into an underwriting agreement in customary form with the underwriter(s) selected for such underwriting.
Notwithstanding any other provision of this Subsection 2.3, if the managing underwriter(s) advise(s) the Initiating Holders in writing that marketing factors require a limitation on the number of shares to be underwritten, then the
Initiating Holders shall so advise all Holders of Registrable Securities that otherwise would be underwritten pursuant hereto, and the number of Registrable Securities that may be included in the underwriting shall be allocated among such Holders of
Registrable Securities, including the Initiating Holders, in proportion (as nearly as practicable) to the number of Registrable Securities owned by each Holder or in such other proportion as shall mutually be agreed to by all such selling Holders;
provided, however, that the number of Registrable Securities held by the Holders to be included in such underwriting shall not be reduced unless all other securities are first entirely excluded from the underwriting. To facilitate the
allocation of shares in accordance with the above provisions, the Company or the underwriters may round the number of shares allocated to any Holder to the nearest one hundred (100) shares. 

(b)    In connection with any offering involving an underwriting of shares of the Company’s capital stock pursuant
to Subsection 2.2, the Company shall not be required to include any of the Holders’ Registrable Securities in such underwriting unless the Holders accept the terms of the underwriting as agreed upon between the Company and its
underwriters, and then only in such quantity as the underwriters in their sole discretion determine will not jeopardize the success of the offering by the Company. If the total number of securities, including Registrable Securities, requested by
stockholders to be included in such offering exceeds the number of securities to be sold (other than by the Company) that the underwriters in their reasonable discretion determine is compatible with the success of the offering, then the Company
shall be required to include in the offering only that number of such securities, including Registrable Securities, which the underwriters and the Company in their sole discretion determine will not jeopardize the success of the offering. If the
underwriters determine that less than all of the Registrable Securities requested to be registered can be included in such offering, then the Registrable Securities that are included in such offering shall be allocated among the selling Holders in
proportion (as nearly as practicable to) the number of Registrable Securities owned by each selling Holder or in such other proportions as shall mutually be agreed to by all such selling Holders. To facilitate the allocation of shares in accordance
with the above provisions, the Company or the underwriters may round the number of shares allocated to any Holder to the nearest one hundred (100) shares. Notwithstanding the foregoing, in no event shall (i) the number of
Registrable Securities included in the offering be reduced unless all other securities (other than securities to be sold by the Company) are first entirely excluded from the offering, or (ii) the number of Registrable Securities included
in the offering be reduced below twenty percent (20%) of the total number of securities included in such offering, unless such offering is the IPO, in which case the selling Holders may be excluded further if the underwriters make the determination
described above and no other stockholder’s securities are included in such offering. For purposes of the provision in this Subsection 2.3(b) concerning apportionment, for any selling Holder that is a partnership, limited liability
company, or corporation, the partners, members, retired partners, 

  
 7 

 
retired members, stockholders, and Affiliates of such Holder, or the estates and Immediate Family Members of any such partners, retired partners, members, and retired members and any trusts for
the benefit of any of the foregoing Persons, shall be deemed to be a single “selling Holder,” and any pro rata reduction with respect to such “selling Holder” shall be based upon the aggregate number of Registrable Securities
owned by all Persons included in such “selling Holder,” as defined in this sentence. 
 (c)    For purposes
of Subsection 2.1, a registration shall not be counted as “effected” if, as a result of an exercise of the underwriter’s cutback provisions in Subsection 2.3(a), fewer than fifty percent (50%) of the total
number of Registrable Securities that Holders have requested to be included in such registration statement are actually included. 

2.4    Obligations of the Company. Whenever required under this Section 2 to effect the registration of
any Registrable Securities, the Company shall, as expeditiously as reasonably possible: 
 (a)    prepare and file with
the SEC a registration statement with respect to such Registrable Securities and use its commercially reasonable efforts to cause such registration statement to become effective and, upon the request of the Holders of a majority of the Registrable
Securities registered thereunder, keep such registration statement effective for a period of up to one hundred twenty (120) days or, if earlier, until the distribution contemplated in the registration statement has been completed;
provided, however, that (i) such one hundred twenty (120) day period shall be extended for a period of time equal to the period the Holder refrains, at the request of an underwriter of Common Stock (or other
securities) of the Company, from selling any securities included in such registration, and (ii) in the case of any registration of Registrable Securities on Form S-3 that are intended to be offered on a continuous or delayed basis,
subject to compliance with applicable SEC rules, such one hundred twenty (120) day period shall be extended, if necessary, to keep the registration statement effective until all such Registrable Securities are sold; 

(b)    prepare and file with the SEC such amendments and supplements to such registration statement, and the prospectus
used in connection with such registration statement, as may be necessary to comply with the Securities Act in order to enable the disposition of all securities covered by such registration statement; 

(c)    furnish to the selling Holders such numbers of copies of a prospectus, including a preliminary prospectus, as
required by the Securities Act, and such other documents as the Holders may reasonably request in order to facilitate their disposition of their Registrable Securities; 

(d)    use its commercially reasonable efforts to register and qualify the securities covered by such registration
statement under such other securities or blue-sky laws of such jurisdictions as shall be reasonably requested by the selling Holders; provided that the Company shall not be required to qualify to do
business or to file a general consent to service of process in any such states or jurisdictions, unless the Company is already subject to service in such jurisdiction and except as may be required by the Securities Act; 

  
 8 

 (e)    in the event of any underwritten public offering, enter into and
perform its obligations under an underwriting agreement, in usual and customary form, with the underwriter(s) of such offering; 

(f)    use its commercially reasonable efforts to cause all such Registrable Securities covered by such registration
statement to be listed on a national securities exchange or trading system and each securities exchange and trading system (if any) on which similar securities issued by the Company are then listed; 

(g)    provide a transfer agent and registrar for all Registrable Securities registered pursuant to this Agreement and
provide a CUSIP number for all such Registrable Securities, in each case not later than the effective date of such registration; 

(h)    promptly make available for inspection by the selling Holders, any managing underwriter(s) participating in any
disposition pursuant to such registration statement, and any attorney or accountant or other agent retained by any such underwriter or selected by the selling Holders, all financial and other records, pertinent corporate documents, and properties of
the Company, and cause the Company’s officers, directors, employees, and independent accountants to supply all information reasonably requested by any such seller, underwriter, attorney, accountant, or agent, in each case, as necessary or
advisable to verify the accuracy of the information in such registration statement and to conduct appropriate due diligence in connection therewith; 

(i)    notify each selling Holder, promptly after the Company receives notice thereof, of the time when such registration
statement has been declared effective or a supplement to any prospectus forming a part of such registration statement has been filed; and 

(j)    after such registration statement becomes effective, notify each selling Holder of any request by the SEC that the
Company amend or supplement such registration statement or prospectus. 
 In addition, the Company shall ensure that, at all times after any registration
statement covering a public offering of securities of the Company under the Securities Act shall have become effective, its insider trading policy shall provide that the Company’s directors may implement a trading program under Rule 10b5-1 of the Exchange Act. 
 2.5    Furnish Information. It shall be a
condition precedent to the obligations of the Company to take any action pursuant to this Section 2 with respect to the Registrable Securities of any selling Holder that such Holder shall furnish to the Company such information regarding
itself, the Registrable Securities held by it, and the intended method of disposition of such securities as is reasonably required to effect the registration of such Holder’s Registrable Securities. 

2.6    Expenses of Registration. All expenses (other than Selling Expenses) incurred in connection with
registrations, filings, or qualifications pursuant to Section 2, including all registration, filing, and qualification fees; printers’ and accounting fees; fees and disbursements of counsel for the Company; and the reasonable fees
and disbursements, not to exceed $50,000, of one counsel for the selling Holders (“Selling Holder Counsel”), shall be borne and paid by the 

  
 9 

 
Company; provided, however, that the Company shall not be required to pay for any expenses of any registration proceeding begun pursuant to Subsection 2.1 if the
registration request is subsequently withdrawn at the request of the Holders of a majority of the Registrable Securities to be registered (in which case all selling Holders shall bear such expenses pro rata based upon the number of Registrable
Securities that were to be included in the withdrawn registration), unless the Holders of a majority of the Registrable Securities agree to forfeit their right to one registration pursuant to Subsections 2.1(a) or 2.1(b), as the
case may be; provided further that if, at the time of such withdrawal, the Holders shall have learned of a material adverse change in the condition, business, or prospects of the Company from that known to the Holders at the time of
their request and have withdrawn the request with reasonable promptness after learning of such information then the Holders shall not be required to pay any of such expenses and shall not forfeit their right to one registration pursuant to
Subsections 2.1(a) or 2.1(b). All Selling Expenses relating to Registrable Securities registered pursuant to this Section 2 shall be borne and paid by the Holders pro rata on the basis of the number of Registrable
Securities registered on their behalf. 
 2.7    Delay of Registration. No Holder shall have any right to obtain
or seek an injunction restraining or otherwise delaying any registration pursuant to this Agreement as the result of any controversy that might arise with respect to the interpretation or implementation of this Section 2. 

2.8    Indemnification. If any Registrable Securities are included in a registration statement under this
Section 2: 
 (a)    To the extent permitted by law, the Company will indemnify and hold harmless each
selling Holder, and the partners, members, officers, directors, and stockholders of each such Holder; legal counsel and accountants for each such Holder; any underwriter (as defined in the Securities Act) for each such Holder; and each Person, if
any, who controls such Holder or underwriter within the meaning of the Securities Act or the Exchange Act, against any Damages, and the Company will pay to each such Holder, underwriter, controlling Person, or other aforementioned Person any legal
or other expenses reasonably incurred thereby in connection with investigating or defending any claim or proceeding from which Damages may result, as such expenses are incurred; provided, however, that the indemnity agreement contained
in this Subsection 2.8(a) shall not apply to amounts paid in settlement of any such claim or proceeding if such settlement is effected without the consent of the Company, which consent shall not be unreasonably withheld, nor shall the
Company be liable for any Damages to the extent that they arise out of or are based upon actions or omissions made in reliance upon and in conformity with written information furnished by or on behalf of any such Holder, underwriter, controlling
Person, or other aforementioned Person expressly for use in connection with such registration. 
 (b)    To the extent
permitted by law, each selling Holder, severally and not jointly, will indemnify and hold harmless the Company, and each of its directors, each of its officers who has signed the registration statement, each Person (if any), who controls the Company
within the meaning of the Securities Act, legal counsel and accountants for the Company, any underwriter (as defined in the Securities Act), any other Holder selling securities in such registration statement, and any controlling Person of any such
underwriter or other Holder, against any Damages, in each case only to the extent that such Damages arise out of or are based upon actions or omissions made in reliance upon and in conformity with written information furnished

  
 10 

 
by or on behalf of such selling Holder expressly for use in connection with such registration; and each such selling Holder will pay to the Company and each other aforementioned Person any legal
or other expenses reasonably incurred thereby in connection with investigating or defending any claim or proceeding from which Damages may result, as such expenses are incurred; provided, however, that the indemnity agreement contained in
this Subsection 2.8(b) shall not apply to amounts paid in settlement of any such claim or proceeding if such settlement is effected without the consent of the Holder, which consent shall not be unreasonably withheld; and provided
further that in no event shall the aggregate amounts payable by any Holder by way of indemnity or contribution under Subsections 2.8(b) and 2.8(d) exceed the proceeds from the offering received by such Holder (net of any
Selling Expenses paid by such Holder), except in the case of fraud or willful misconduct by such Holder. 

(c)    Promptly after receipt by an indemnified party under this Subsection 2.8 of notice of the commencement
of any action (including any governmental action) for which a party may be entitled to indemnification hereunder, such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this
Subsection 2.8, give the indemnifying party notice of the commencement thereof. The indemnifying party shall have the right to participate in such action and, to the extent the indemnifying party so desires, participate jointly with any
other indemnifying party to which notice has been given, and to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified party (together with all other indemnified parties
that may be represented without conflict by one counsel) shall have the right to retain one separate counsel, with the fees and expenses to be paid by the indemnifying party, if representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to actual or potential differing interests between such indemnified party and any other party represented by such counsel in such action. The failure to give notice to the indemnifying party within a
reasonable time of the commencement of any such action shall relieve such indemnifying party of any liability to the indemnified party under this Subsection 2.8 only to the extent that such failure materially prejudices the indemnifying
party’s ability to defend such action. The failure to give notice to the indemnifying party will not relieve it of any liability that it may have to any indemnified party otherwise than under this Subsection 2.8. 

(d)    To provide for just and equitable contribution to joint liability under the Securities Act in any case in which
either: (i) any party otherwise entitled to indemnification hereunder makes a claim for indemnification pursuant to this Subsection 2.8 but it is judicially determined (by the entry of a final judgment or decree by a court of
competent jurisdiction and the expiration of time to appeal or the denial of the last right of appeal) that such indemnification may not be enforced in such case, notwithstanding the fact that this Subsection 2.8 provides for
indemnification in such case, or (ii) contribution under the Securities Act may be required on the part of any party hereto for which indemnification is provided under this Subsection 2.8, then, and in each such case, such
parties will contribute to the aggregate losses, claims, damages, liabilities, or expenses to which they may be subject (after contribution from others) in such proportion as is appropriate to reflect the relative fault of each of the indemnifying
party and the indemnified party in connection with the statements, omissions, or other actions that resulted in such loss, claim, damage, liability, or expense, as well as to reflect any other relevant equitable considerations. The relative fault of
the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether the untrue or allegedly untrue statement of a material 

  
 11 

 
fact, or the omission or alleged omission of a material fact, relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent,
knowledge, access to information, and opportunity to correct or prevent such statement or omission; provided, however, that, in any such case (x) no Holder will be required to contribute any amount in excess of the public offering
price of all such Registrable Securities offered and sold by such Holder pursuant to such registration statement, and (y) no Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities
Act) will be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation; and provided further that in no event shall a Holder’s liability pursuant to this Subsection 2.8(d), when
combined with the amounts paid or payable by such Holder pursuant to Subsection 2.8(b), exceed the proceeds from the offering received by such Holder (net of any Selling Expenses paid by such Holder), except in the case of willful
misconduct or fraud by such Holder. 
 (e)    Notwithstanding the foregoing, to the extent that the provisions on
indemnification and contribution contained in the underwriting agreement entered into in connection with the underwritten public offering are in conflict with the foregoing provisions, the provisions in the underwriting agreement shall control. 

(f)    Unless otherwise superseded by an underwriting agreement entered into in connection with the underwritten public
offering, the obligations of the Company and Holders under this Subsection 2.8 shall survive the completion of any offering of Registrable Securities in a registration under this Section 2, and otherwise shall survive the
termination of this Agreement. 
 2.9    Reports Under Exchange Act. With a view to making available to the
Holders the benefits of SEC Rule 144 and any other rule or regulation of the SEC that may at any time permit a Holder to sell securities of the Company to the public without registration or pursuant to a registration on Form S-3, the Company shall: 
 (a)    make and keep available adequate current public
information, as those terms are understood and defined in SEC Rule 144, at all times after the effective date of the registration statement filed by the Company for the IPO; 

(b)    use commercially reasonable efforts to file with the SEC in a timely manner all reports and other documents
required of the Company under the Securities Act and the Exchange Act (at any time after the Company has become subject to such reporting requirements); and 

(c)    furnish to any Holder, so long as the Holder owns any Registrable Securities, forthwith upon request (i) to the
extent accurate, a written statement by the Company that it has complied with the reporting requirements of SEC Rule 144 (at any time after ninety (90) days after the effective date of the registration statement filed by the Company for the
IPO), the Securities Act, and the Exchange Act (at any time after the Company has become subject to such reporting requirements), or that it qualifies as a registrant whose securities may be resold pursuant to Form S-3 (at any time after the Company
so qualifies); and (ii) such other information as may be reasonably requested in availing any Holder of any rule or regulation of the SEC that permits the selling of any such securities without registration (at any time after the Company
has become subject to the reporting requirements under the Exchange Act) or pursuant to Form S-3 (at any time after the Company so qualifies to use such form). 

  
 12 

 2.10    Limitations on Subsequent Registration Rights. From and
after the date of this Agreement, the Company shall not, without the prior written consent of the Holders of a majority of the Registrable Securities then outstanding, enter into any agreement with any holder or prospective holder of any securities
of the Company that would (i) allow such holder or prospective holder to include such securities in any registration unless, under the terms of such agreement, such holder or prospective holder may include such securities in any such
registration only to the extent that the inclusion of such securities will not reduce the number of the Registrable Securities of the Holders that are included; or (ii) allow such holder or prospective holder to initiate a demand for
registration of any securities held by such holder or prospective holder; provided that this limitation shall not apply to Registrable Securities acquired by any additional Investor that becomes a party to this Agreement in accordance with
Subsection 6.9. 
 2.11    “Market Stand-off”
Agreement. Each Holder hereby agrees that it will not, without the prior written consent of the managing underwriter, during the period commencing on the date of the final prospectus relating to the registration by the Company for its own behalf
of shares of its Common Stock or any other equity securities under the Securities Act on a registration statement on Form S-1 or Form S-3, and ending on the date
specified by the Company and the managing underwriter (such period not to exceed one hundred eighty (180) days in the case of the IPO, or such other period as may be requested by the Company or an underwriter to accommodate regulatory
restrictions on (1) the publication or other distribution of research reports, and (2) analyst recommendations and opinions, including, but not limited to, the restrictions contained in FINRA Rule 2711(f)(4) or NYSE Rule 472(f)(4), or any successor
provisions or amendments thereto), or ninety (90) days in the case of any registration other than the IPO, or such other period as may be requested by the Company or an underwriter to accommodate regulatory restrictions on (1) the publication or
other distribution of research reports and (2) analyst recommendations and opinions, including, but not limited to, the restrictions contained in FINRA Rule 2711(f)(4) or NYSE Rule 472(f)(4), or any successor provisions or amendments thereto), (i)
lend; offer; pledge; sell; contract to sell; sell any option or contract to purchase; purchase any option or contract to sell; grant any option, right, or warrant to purchase; or otherwise transfer or dispose of, directly or indirectly, any shares
of Common Stock or any securities convertible into or exercisable or exchangeable (directly or indirectly) for Common Stock held immediately before the effective date of the registration statement for such offering or (ii) enter into any swap
or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of such securities, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Common Stock or
other securities, in cash, or otherwise. The foregoing provisions of this Subsection 2.11 shall not apply to the sale of any shares to an underwriter pursuant to an underwriting agreement, or the transfer of any shares to any trust for the
direct or indirect benefit of the Holder or the immediate family of the Holder, provided that the trustee of the trust agrees to be bound in writing by the restrictions set forth herein, and provided further that any such
transfer shall not involve a disposition for value, and shall be applicable to the Holders only if all officers and directors are subject to the same restrictions and the Company uses commercially reasonable efforts to obtain a similar agreement
from all stockholders individually owning more than one percent (1%) of the Company’s outstanding Common Stock (after giving effect to conversion into Common Stock of all outstanding Series B Preferred Stock and Series C Preferred

  
 13 

 
Stock). The underwriters in connection with such registration are intended third-party beneficiaries of this Subsection 2.11 and shall have the right, power and authority to enforce
the provisions hereof as though they were a party hereto. Each Holder further agrees to execute such agreements as may be reasonably requested by the underwriters in connection with such registration that are consistent with this
Subsection 2.11 or that are necessary to give further effect thereto. 
 2.12    Restrictions on
Transfer. 
 (a)    The Series B Preferred Stock, Series C Preferred Stock and the Registrable
Securities shall not be sold, pledged, or otherwise transferred, and the Company shall not recognize and shall issue stop-transfer instructions to its transfer agent with respect to any such sale, pledge, or transfer, except upon the conditions
specified in this Agreement, which conditions are intended to ensure compliance with the provisions of the Securities Act. A transferring Holder will cause any proposed purchaser, pledgee, or transferee of the Series B Preferred Stock,
Series C Preferred Stock and the Registrable Securities held by such Holder to agree to take and hold such securities subject to the provisions and upon the conditions specified in this Agreement. In addition, except as otherwise
expressly permitted by Section 7 of Article IV(B) of the Certificate of Incorporation, the Founder Preferred Stock shall not be sold, pledged or other otherwise transferred, and the Company shall not recognize and shall issue
stop-transfer instructions to its transfer agent with respect to any such sale, pledge, or transfer, unless such transfer is approved in writing in advance by the holders of a majority of the Registrable Securities issued or issuable upon conversion
of the Series B Preferred Stock and Series C Preferred Stock. 
 (b)    Each certificate,
instrument, or book entry representing (i) the Series B Preferred Stock, (ii) the Series C Preferred Stock; (iii) the Registrable Securities, (iv) the Founder Preferred Stock and
(v) any other securities issued in respect of the securities referenced in clauses (i) through (iv), upon any stock split, stock dividend, recapitalization, merger, consolidation, or similar event, shall (unless otherwise
permitted by the provisions of Subsection 2.12(c)) be notated with a legend substantially in the following form: 
 THE
SECURITIES REPRESENTED HEREBY HAVE BEEN ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933. SUCH SHARES MAY NOT BE SOLD, PLEDGED, OR TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR A VALID EXEMPTION FROM THE
REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF SAID ACT. 
 THE SECURITIES REPRESENTED HEREBY MAY BE TRANSFERRED ONLY IN ACCORDANCE
WITH THE TERMS OF AN AGREEMENT BETWEEN THE COMPANY AND THE STOCKHOLDER, A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF THE COMPANY. 
 The Holders consent
to the Company making a notation in its records and giving instructions to any transfer agent of the Restricted Securities in order to implement the restrictions on transfer set forth in this Subsection 2.12. 

  
 14 

 (c)    The holder of such Restricted Securities, by acceptance of
ownership thereof, agrees to comply in all respects with the provisions of this Section 2. Before any proposed sale, pledge, or transfer of any Restricted Securities, unless there is in effect a registration statement under the
Securities Act covering the proposed transaction, the Holder thereof shall give notice to the Company of such Holder’s intention to effect such sale, pledge, or transfer. Each such notice shall describe the manner and circumstances of the
proposed sale, pledge, or transfer in sufficient detail and, if reasonably requested by the Company, shall be accompanied at such Holder’s expense by either (i) a written opinion of legal counsel who shall, and whose legal opinion
shall, be reasonably satisfactory to the Company, addressed to the Company, to the effect that the proposed transaction may be effected without registration under the Securities Act; (ii) a “no action” letter from the SEC to
the effect that the proposed sale, pledge, or transfer of such Restricted Securities without registration will not result in a recommendation by the staff of the SEC that action be taken with respect thereto; or (iii) any other evidence
reasonably satisfactory to counsel to the Company to the effect that the proposed sale, pledge, or transfer of the Restricted Securities may be effected without registration under the Securities Act, whereupon the Holder of such Restricted
Securities shall be entitled to sell, pledge, or transfer such Restricted Securities in accordance with the terms of the notice given by the Holder to the Company. The Company will not require such a legal opinion or “no action” letter
(x) in any transaction in compliance with SEC Rule 144; or (y) in any transaction in which such Holder distributes Restricted Securities to an Affiliate of such Holder for no consideration; provided that each
transferee agrees in writing to be subject to the terms of this Subsection 2.12. Each certificate, instrument, or book entry representing the Restricted Securities transferred as above provided shall be notated with, except if such
transfer is made pursuant to SEC Rule 144, the appropriate restrictive legend set forth in Subsection 2.12(b), except that such certificate instrument, or book entry shall not be notated with such restrictive legend if, in the opinion of
counsel for such Holder and the Company, such legend is not required in order to establish compliance with any provisions of the Securities Act. 

2.13    Termination of Registration Rights. The right of any Holder to request registration or inclusion of
Registrable Securities in any registration pursuant to Subsections 2.1 or 2.2 shall terminate upon the earliest to occur of: 

(a)    the closing of a Deemed Liquidation Event, as such term is defined in the Certificate of Incorporation; 

(b)    such time after consummation of the IPO as Rule 144 or another similar exemption under the Securities Act is
available for the sale of all of such Holder’s shares without limitation during a three-month period without registration; 

(c)    the fifth (5th) anniversary of the IPO. 

3.    Information and Observer Rights. 

3.1    Delivery of Financial Statements. The Company shall deliver to each Major Investor: 

(a)    as soon as practicable, but in any event within ninety (90) days after the end of each fiscal year of the
Company (i) a balance sheet as of the end of such year, (ii) statements of income and of cash flows for such year, and (iii) a statement of stockholders’ equity as of the end of such year, with all such
financial statements for fiscal year 2019 and following audited and certified by independent public accountants of nationally recognized standing selected by the Company; 

  
 15 

 (b)    as soon as practicable, but in any event within forty-five
(45) days after the end of each of the first three (3) quarters of each fiscal year of the Company, unaudited statements of income and cash flows for such fiscal quarter, and an unaudited balance sheet as of the end of such fiscal
quarter, all prepared in accordance with GAAP (except that such financial statements may (i) be subject to normal year-end audit adjustments; and (ii) not contain all notes thereto that may be required in accordance with
GAAP); and 
 (c)    as soon as practicable, but in any event within forty-five (45) days after the end of each of
the first three (3) quarters of each fiscal year of the Company, a statement showing the number of shares of each class and series of capital stock and securities convertible into or exercisable for shares of capital stock outstanding at
the end of the period, the Common Stock issuable upon conversion or exercise of any outstanding securities convertible or exercisable for Common Stock and the exchange ratio or exercise price applicable thereto, and the number of shares of issued
stock options and stock options not yet issued but reserved for issuance, if any, all in sufficient detail as to permit the Major Investors to calculate their respective percentage equity ownership in the Company, and certified by the chief
financial officer or chief executive officer of the Company as being true, complete, and correct. 
 Notwithstanding anything else in this
Subsection 3.1 to the contrary, the Company shall not be obligated under this Subsection 3.1 to provide information (i) that the Company reasonably determines in good faith to be a trade
secret or confidential information; provided, however, that normal and customary financial information and data appearing in the Company’s financial statements shall not be deemed to be a trade secret or confidential information for purposes of
this paragraph; or (ii) the disclosure of which would adversely affect the attorney-client privilege between the Company and its counsel. 
 If, for
any period, the Company has any subsidiary whose accounts are consolidated with those of the Company, then in respect of such period the financial statements delivered pursuant to the foregoing sections shall be the consolidated and consolidating
financial statements of the Company and all such consolidated subsidiaries. Notwithstanding anything else in this Subsection 3.1 to the contrary, the Company may cease providing the information set forth in this
Subsection 3.1 during the period starting with the date thirty (30) days before the Company’s good-faith estimate of the date of filing of a registration statement if it reasonably concludes it must do so to
comply with the SEC rules applicable to such registration statement and related offering; provided that the Company’s covenants under this Subsection 3.1 shall be reinstated at such time as the Company is no
longer actively employing its commercially reasonable efforts to cause such registration statement to become effective. 

3.2    Inspection. The Company shall permit each Major Investor, at such Major Investor’s expense, to visit
and inspect the Company’s properties; examine its books of account 

  
 16 

 
and records; and discuss the Company’s affairs, finances, and accounts with its officers, during normal business hours of the Company as may be reasonably requested by the Major Investor;
provided, however, that the Company shall not be obligated pursuant to this Subsection 3.2 to provide access to any information that it reasonably and in good faith considers to be a trade secret or confidential information
(unless covered by an enforceable confidentiality agreement, in form acceptable to the Company) or the disclosure of which would adversely affect the attorney-client privilege between the Company and its counsel. 

3.3    Observer Rights. As long as Northpond Ventures, LP owns shares of the capital stock of the Company, the
Company shall invite a representative of Northpond Ventures, LP to attend all meetings of the Board of Directors in a nonvoting observer capacity and, in this respect, shall give such representative copies of all notices, minutes, consents, and
other materials that it provides to its directors at the same time and in the same manner as provided to such directors; provided, however, that such representative shall agree to hold in confidence and trust and to act in a fiduciary manner with
respect to all information so provided; and provided further, that the Company reserves the right to withhold any information and to exclude such representative from any meeting or portion thereof if access to such information or attendance at such
meeting could adversely affect the attorney-client privilege between the Company and its counsel or result in disclosure of trade secrets or a conflict of interest, if such Investor or its representative is a competitor of the Company. 

3.4    Termination of Information Rights and Observer Rights. The covenants set forth in
Subsection 3.1, Subsection 3.2 and Subsection 3.3 shall terminate and be of no further force or effect (i) immediately before the consummation of the IPO, (ii) when the Company first
becomes subject to the periodic reporting requirements of Section 12(g) or 15(d) of the Exchange Act, or (iii) upon the closing of a Deemed Liquidation Event, as such term is defined in the Certificate of
Incorporation, whichever event occurs first. 
 3.5    Confidentiality. Each Investor agrees that such Investor
will keep confidential and will not disclose, divulge, or use for any purpose (other than to monitor its investment in the Company) any confidential information obtained from the Company pursuant to the terms of this Agreement (including notice of
the Company’s intention to file a registration statement), unless such confidential information (a) is known or becomes known to the public in general (other than as a result of a breach of this Subsection 3.5 by such Investor), (b)
is or has been independently developed or conceived by such Investor without use of the Company’s confidential information, or (c) is or has been made known or disclosed to such Investor by a third party without a breach of any obligation of
confidentiality such third party may have to the Company; provided, however, that an Investor may disclose confidential information (i) to its attorneys, accountants, consultants, and other professionals to the extent
necessary to obtain their services in connection with monitoring its investment in the Company; (ii) to any prospective purchaser of any Registrable Securities from such Investor, if such prospective purchaser agrees to be bound by the
provisions of this Subsection 3.5; (iii) to any existing or prospective Affiliate, partner, member, stockholder, or wholly owned subsidiary of such Investor in the ordinary course of business, provided that such
Investor informs such Person that such information is confidential and directs such Person to maintain the confidentiality of such information; or (iv) as may otherwise be required by law, regulation, rule, court order or subpoena,
provided that such Investor promptly notifies the Company of such disclosure and takes reasonable steps to minimize the extent of any such required disclosure.

 4.    Rights to Future Stock Issuances. 

4.1    Right of First Offer. Subject to the terms and conditions of this Subsection 4.1 and applicable
securities laws, if the Company proposes to offer or sell any New Securities, the Company shall first offer such New Securities to each Major Investor. A Major Investor shall be entitled to apportion the right of first offer hereby granted to it in
such proportions as it deems appropriate, among (i) itself, (ii) its Affiliates and (iii) its beneficial interest holders, such as limited partners, members or any other Person having “beneficial ownership,” as such
term is defined in Rule 13d-3 promulgated under the Exchange Act, of such Major Investor (“Investor Beneficial Owners”); provided that each such Affiliate or Investor Beneficial Owner agrees to enter into this Agreement and
each of the Voting Agreement and Right of First Refusal and Co-Sale Agreement of even date herewith among the Company, the Investors and the other parties named therein, as an “Investor” under each such agreement. 

(a)    The Company shall give notice (the “Offer Notice”) to each Major Investor, stating (i) its
bona fide intention to offer such New Securities, (ii) the number of such New Securities to be offered, and (iii) the price and terms, if any, upon which it proposes to offer such New Securities. 

(b)    By notification to the Company within twenty (20) days after the Offer Notice is given, each Major Investor
may elect to purchase or otherwise acquire, at the price and on the terms specified in the Offer Notice, up to that portion of such New Securities which equals the proportion that the Common Stock then held by such Major Investor (including all
shares of Common Stock then issuable (directly or indirectly) upon conversion and/or exercise, as applicable, of the Series B Preferred Stock, the Series C Preferred Stock and any other Derivative Securities then held by such
Major Investor) bears to the total Common Stock of the Company then held by all the Major Investors (including all shares of Common Stock issuable (directly or indirectly) upon conversion and/or exercise, as applicable, of the Series B
Preferred Stock, the Series C Preferred Stock and any other Derivative Securities then held by all the Major Investors) (such portion of such New Securities, the “Pro Rata Amount”). At the expiration of such twenty
(20) day period, the Company shall promptly notify each Major Investor that elects to purchase or acquire all the shares available to it (each, a “Fully Exercising Investor”) of any other Major Investor’s failure to
do likewise. During the ten (10) day period commencing after the Company has given such notice, each Fully Exercising Investor may, by giving notice to the Company, elect to purchase or acquire, in addition to the number of shares
specified above, up to that portion of the New Securities for which Major Investors were entitled to subscribe but that were not subscribed for by the Major Investors which is equal to the proportion that the Common Stock issued and held, or
issuable (directly or indirectly) upon conversion and/or exercise, as applicable, of Series B Preferred Stock, Series C Preferred Stock and any other Derivative Securities then held, by such Fully Exercising Investor bears to
the Common Stock issued and held, or issuable (directly or indirectly) upon conversion and/or exercise, as applicable, of the Series B Preferred Stock, the Series C Preferred Stock and any other Derivative Securities then
held, by all Fully Exercising Investors who wish to purchase such unsubscribed shares. The closing of any sale pursuant to this Subsection 4.1(b) shall occur within the later of ninety (90) days of the date that the Offer Notice is given
and the date of initial sale of New Securities pursuant to Subsection 4.1(c). 

  
 18 

 (c)    If all New Securities referred to in the Offer
Notice are not elected to be purchased or acquired as provided in Subsection 4.1(b), the Company may, during the ninety (90) day period following the expiration of the periods provided in Subsection 4.1(b), offer
and sell the remaining unsubscribed portion of such New Securities to any Person or Persons at a price not less than, and upon terms no more favorable to the offeree than, those specified in the Offer Notice. If the Company does not enter into an
agreement for the sale of the New Securities within such period, or if such agreement is not consummated within thirty (30) days of the execution thereof, the right provided hereunder shall be deemed to be revived and such New Securities
shall not be offered unless first reoffered to the Major Investors in accordance with this Subsection 4.1. 

(d)    The right of first offer in this Subsection 4.1 shall not be applicable to (i) Exempted
Securities (as defined in the Certificate of Incorporation); and (ii) shares of Common Stock issued in the IPO. 

4.2    Termination. The covenants set forth in Subsection 4.1 shall terminate and be of no further
force or effect (i) immediately before the consummation of the IPO, or (ii) upon the closing of a Deemed Liquidation Event, as such term is defined in the Certificate of Incorporation, whichever event occurs first. 

5.    Additional Covenants. 

5.1    Employee Agreements. The Company will cause (i) each Person now or hereafter employed by it or by any
subsidiary (or engaged by the Company or any subsidiary as a consultant/independent contractor) with access to confidential information and/or trade secrets to enter into a nondisclosure and proprietary rights assignment agreement; and
(ii) each Key Employee to enter into a one (1) year nonsolicitation agreement and, if and to the extent legally permissible and/or enforceable in a jurisdiction in which a given employee is employed, a one
(1) year noncompetition agreement, each substantially in the form approved by the Board of Directors. In addition, the Company shall not amend, modify, terminate, waive, or otherwise alter, in whole or in part, any of the
above-referenced agreements or any restricted stock agreement between the Company and any employee, without the consent of at least a majority of the Series B Directors. 

5.2    Employee Stock. Unless otherwise approved by the Board of Directors, including (i) at least a majority
of the Series B Directors and (ii) in the event any applicable employee or consultant is an affiliate of PBM, the Series C Director, all future employees and consultants of the Company who purchase, receive
options to purchase, or receive awards of shares of the Company’s capital stock after the date hereof shall be required to execute restricted stock or option agreements, as applicable, providing for (i) vesting of shares over a four
(4) year period, with the first twenty-five percent (25%) of such shares vesting following twelve (12) months of continued employment or service, and the remaining shares vesting in equal monthly installments over the
following thirty-six (36) months, and (ii) a market stand-off provision substantially similar to that in Subsection 2.11. Without the prior approval by the Board of Directors, including (i) at least a
majority of the Series B Directors and (ii) in the event any applicable employee or consultant is an affiliate of PBM, the Series C Director, the Company shall not on or after the date

  
 19 

 
hereof amend, modify, terminate, waive or otherwise alter, in whole or in part, any stock purchase, stock restriction or option agreement with any existing employee or service provider if such
amendment would cause it to be inconsistent with this Subsection 5.2. In addition, unless otherwise approved by the Board of Directors, including at least a majority of the Series B Directors, or unless otherwise stated in a
written agreement existing as of the date hereof between an employee and the Company, the Company shall retain (and not waive) a “right of first refusal” on employee transfers until the Company’s IPO and shall have the right to
repurchase unvested shares at cost upon termination of employment of a holder of restricted stock. 
 5.3    Matters
Requiring Preferred Director Approval. In addition to any other approvals required under the Certificate of Incorporation or applicable law, so long as the holders of Series B Preferred Stock are entitled to elect a Series B
Director, or the holders of Series C Preferred Stock are entitled to elect a Series C Director, the Company hereby covenants and agrees with each of the Investors that it shall not, without approval of the Board of Directors,
which approval must include the affirmative vote of (i) at least a majority of the Series B Directors and (ii) in the event any applicable transaction is with PBM or an affiliate of PBM, the Series C
Director: 
 (a)    make, or permit any subsidiary to make, any loan or advance to, or own any stock or other
securities of, any subsidiary or other corporation, partnership, or other entity unless it is wholly owned by the Company; 

(b)    make, or permit any subsidiary to make, any loan or advance to any Person, including, without limitation, any
employee or director of the Company or any subsidiary, except advances and similar expenditures in the ordinary course of business or under the terms of an employee stock or option plan approved by the Board of Directors; 

(c)    guarantee, directly or indirectly, or permit any subsidiary to guarantee, directly or indirectly, any indebtedness
except for trade accounts of the Company or any subsidiary arising in the ordinary course of business; 
 (d)    make
any investment inconsistent with any investment policy approved by the Board of Directors; 
 (e)    approve any annual
operating budget or make any material revision to any annual operating budget previously approved; 
 (f)    incur any
indebtedness or authorize any expenditure or any commitment to make any expenditure not contemplated by an annual operating budget that has been approved by the Board of Directors pursuant to Section 5.3(e); 

(g)    enter into or be a party to any transaction with any director, officer, or employee of the Company or any
“associate” (as defined in Rule 12b-2 promulgated under the Exchange Act) of any such Person, including without limitation any “management bonus” or similar plan providing payments to
employees in connection with a Deemed Liquidation Event, as such term is defined in the Certificate of Incorporation, except for transactions entered into prior to the date hereof or contemplated by this Agreement; 

  
 20 

 (h)    amend the material terms of any agreement or transaction with
any director or executive officer of the Company or any “associate” (as defined in Rule 12b-2 promulgated under the Exchange Act) of any such Person that is authorized pursuant to Section 5.3(g); 

(i)    hire, terminate, or change the compensation of the executive officers, including approving any option grants or
stock awards to executive officers; 
 (j)    change the principal business of the Company, enter new lines of
business, or exit the current line of business; 
 (k)    sell, assign, license, pledge, or encumber material
technology or intellectual property, other than licenses granted in the ordinary course of business; or 
 (l)    enter
into any corporate strategic relationship, other than any such strategic relationships entered into prior to the date hereof, involving the payment, contribution, or assignment by the Company or to the Company of money or assets greater than
$200,000. 
 5.4    Board Matters. Unless otherwise determined by the vote of a majority of the directors then in
office, including at least a majority of the Preferred Directors, the Board of Directors shall meet at least quarterly in accordance with an agreed-upon schedule. The Company shall reimburse the nonemployee directors for all reasonable out-of-pocket travel expenses incurred (consistent with the Company’s travel policy) in connection with attending meetings of the Board of Directors. Each Preferred
Director shall be entitled in such person’s discretion to be a member of any committee of the Board of Directors. 

5.5    Successor Indemnification. If the Company or any of its successors or assignees consolidates with or merges
into any other Person and is not the continuing or surviving corporation or entity of such consolidation or merger, then to the extent necessary, proper provision shall be made so that the successors and assignees of the Company assume the
obligations of the Company with respect to indemnification of members of the Board of Directors as in effect immediately before such transaction, whether such obligations are contained in the Company’s Bylaws, the Certificate of Incorporation,
or elsewhere, as the case may be. 
 5.6    Indemnification Matters. The Company hereby acknowledges that
one (1) or more of the directors nominated to serve on the Board of Directors by the Investors (each an “Investor Director”) may have certain rights to indemnification, advancement of expenses and/or insurance provided by one
or more of the Investors and certain of their Affiliates (collectively, the “Investor Indemnitors”). The Company hereby agrees (a) that it is the indemnitor of first resort (i.e., its obligations to any such Investor
Director are primary and any obligation of the Investor Indemnitors to advance expenses or to provide indemnification for the same expenses or liabilities incurred by such Investor Director are secondary), (b) that it shall be required to advance
the full amount of expenses incurred by such Investor Director and shall be liable for the full amount of all expenses, judgments, penalties, fines and amounts paid in settlement by or on behalf of any such Investor Director to the extent legally
permitted and as required by the Company’s Certificate of Incorporation or Bylaws of the Company (or any agreement between the Company and such Investor Director), without regard to any rights such Investor Director may have against the

  
 21 

 
Investor Indemnitors, and, (c) that it irrevocably waives, relinquishes and releases the Investor Indemnitors from any and all claims against the Investor Indemnitors for contribution,
subrogation or any other recovery of any kind in respect thereof. The Company further agrees that no advancement or payment by the Investor Indemnitors on behalf of any such Investor Director with respect to any claim for which such Investor
Director has sought indemnification from the Company shall affect the foregoing and the Investor Indemnitors shall have a right of contribution and/or be subrogated to the extent of such advancement or payment to all of the rights of recovery of
such Investor Director against the Company. The Investor Directors and the Investor Indemnitors are intended third-party beneficiaries of this Subsection 5.6 and shall have the right, power and authority to enforce the provisions of this
Subsection 5.6 as though they were a party to this Agreement. 
 5.7    Right to Conduct Activities.
The Company hereby agrees and acknowledges that each of PBM (together with its Affiliates), Northpond Ventures LP (together with its Affiliates), and Sands Capital Global Venture Fund II, L.P. (together with its Affiliates, and with PBM and
Northpond Ventures LP and their Affiliates collectively, the “Funds”) is a professional investment organization, and as such reviews the business plans and related proprietary information of many enterprises, some of which may
compete directly or indirectly with the Company’s business (as currently conducted or as currently propose to be conducted). The Company hereby agrees that, to the extent permitted under applicable law, the Funds (and their Affiliates) shall
not be liable to the Company for any claim arising out of, or based upon, (i) the investment by the Funds (or their Affiliates) in any entity competitive with the Company, or (ii) actions taken by any partner, officer, employee or
other representative of the Funds (or their Affiliates) to assist any such competitive company, whether or not such action was taken as a member of the board of directors of such competitive company or otherwise, and whether or not such action has a
detrimental effect on the Company; provided, however, that the foregoing shall not relieve (x) any of the Investors from liability associated with the unauthorized disclosure of the Company’s confidential information obtained
pursuant to this Agreement, or (y) any director or officer of the Company from any liability associated with his or her fiduciary duties to the Company. A Major Investor may display the Company’s name and logo on its website and
other promotional material for the sole purpose of advertising that such Major Investor purchased securities of the Company. 

5.8    Insurance. For so long as a Preferred Director is serving on the Board of Directors, the Company shall not
cease to maintain a Directors and Officers liability insurance policy in an amount of at least three (3) million dollars unless approved by a majority of the Preferred Directors, including the Series C Director, and the Company
shall annually, within one hundred twenty (120) days after the end of each fiscal year of the Company, deliver to each Preferred Director a certification that such a Directors and Officers liability insurance policy remains in effect.

 5.9    Termination of Covenants. The covenants set forth in this Section 5, except for
Subsections 5.5, 5.6 and 5.7, shall terminate and be of no further force or effect (i) immediately before the consummation of the IPO, or (ii) upon a Deemed Liquidation Event, as such term is defined
in the Certificate of Incorporation, whichever event occurs first. 

  
 22 

 6.    Miscellaneous. 

6.1    Successors and Assigns. The rights under this Agreement may be assigned (but only with all related
obligations) by a Holder to a transferee of Registrable Securities that (i) is an Affiliate of a Holder; (ii) is a Holder’s Immediate Family Member or trust for the benefit of an individual Holder or one or more of such
Holder’s Immediate Family Members; or (iii) after such transfer, holds at least 100,000 shares of Registrable Securities (subject to appropriate adjustment for stock splits, stock dividends, combinations, and other
recapitalizations); provided, however, that (x) the Company is, within a reasonable time after such transfer, furnished with written notice of the name and address of such transferee and the Registrable Securities with
respect to which such rights are being transferred; and (y) such transferee agrees in a written instrument delivered to the Company to be bound by and subject to the terms and conditions of this Agreement, including the provisions of
Subsection 2.11. For the purposes of determining the number of shares of Registrable Securities held by a transferee, the holdings of a transferee (1) that is an Affiliate or stockholder of a Holder; (2) who is a
Holder’s Immediate Family Member; or (3) that is a trust for the benefit of an individual Holder or such Holder’s Immediate Family Member shall be aggregated together and with those of the transferring Holder; provided
further that all transferees who would not qualify individually for assignment of rights shall, as a condition to the applicable transfer, establish a single
attorney-in-fact for the purpose of exercising any rights, receiving notices, or taking any action under this Agreement. The terms and conditions of this Agreement inure
to the benefit of and are binding upon the respective successors and permitted assignees of the parties. Nothing in this Agreement, express or implied, is intended to confer upon any party other than the parties hereto or their respective successors
and permitted assignees any rights, remedies, obligations or liabilities under or by reason of this Agreement, except as expressly provided herein. 

6.2    Governing Law. This Agreement shall be governed by the internal law of the State of Delaware, without regard
to conflict of law principles that would result in the application of any law other than the law of the State of Delaware. 

6.3    Counterparts. This Agreement may be executed in two (2) or more counterparts, each of which shall be
deemed an original, but all of which together shall constitute one and the same instrument. Counterparts may be delivered via facsimile, electronic mail (including pdf or any electronic signature complying with the U.S. federal ESIGN Act of 2000,
e.g., www.docusign.com) or other transmission method and any counterpart so delivered shall be deemed to have been duly and validly delivered and be valid and effective for all purposes. 

6.4    Titles and Subtitles. The titles and subtitles used in this Agreement are for convenience only and are not
to be considered in construing or interpreting this Agreement. 
 6.5    Notices. 

(a)    All notices and other communications given or made pursuant to this Agreement shall be in writing and shall be
deemed effectively given upon the earlier of actual receipt or (i) personal delivery to the party to be notified; (ii) when sent, if sent by electronic mail during the recipient’s normal business hours, and if not sent during
normal business hours, then on the recipient’s next business day; (iii) five (5) days after having been sent by registered or certified mail, return receipt requested, postage prepaid; or (iv) one
(1) business day after the business day of deposit with a nationally recognized overnight courier, freight prepaid, specifying 

  
 23 

 
next-day delivery, with written verification of receipt. All communications shall be sent to the respective parties at their addresses as set forth on Schedule A hereto, or to the
principal office of the Company and to the attention of the Chief Executive Officer, in the case of the Company, or to such email address or address as subsequently modified by written notice given in accordance with this Subsection 6.5.
If notice is given to the Company, a copy shall also be sent to William Collins, Goodwin Procter LLP, 100 Northern Avenue, Boston, MA 02210 

(b)    Consent to Electronic Notice. Each Investor consents to the delivery of any stockholder notice pursuant to
the Delaware General Corporation Law (the “DGCL”), as amended or superseded from time to time, by electronic transmission pursuant to Section 232 of the DGCL (or any successor thereto) at the electronic mail address set forth
below such Investor’s name on the Schedules hereto, as updated from time to time by notice to the Company, or as on the books of the Company. To the extent that any notice given by means of electronic transmission is returned or undeliverable
for any reason, the foregoing consent shall be deemed to have been revoked until a new or corrected electronic mail address has been provided, and such attempted Electronic Notice shall be ineffective and deemed to not have been given. Each Investor
agrees to promptly notify the Company of any change in such stockholder’s electronic mail address, and that failure to do so shall not affect the foregoing. 

6.6    Amendments and Waivers. Any term of this Agreement may be amended, modified or terminated and the observance
of any term of this Agreement may be waived (either generally or in a particular instance, and either retroactively or prospectively) only with the written consent of (i) the Company, (ii) the holders of at least a majority of the
Registrable Securities then outstanding, and (iii) the holders of a majority of the then-outstanding shares of Founder Preferred Stock; provided that the Company may in its sole discretion waive compliance with
Subsection 2.12(c) (and the Company’s failure to object promptly in writing after notification of a proposed assignment allegedly in violation of Subsection 2.12(c) shall be deemed to be a waiver); and provided
further that any provision hereof may be waived by any waiving party on such party’s own behalf, without the consent of any other party. Notwithstanding the foregoing, (a) this Agreement may not be amended, modified or
terminated and the observance of any term hereof may not be waived with respect to any Investor without the written consent of such Investor, unless such amendment, modification, termination, or waiver applies to all Investors in the same fashion
(it being agreed that a waiver of the provisions of Section 4 with respect to a particular transaction shall be deemed to apply to all Investors in the same fashion if such waiver does so by its terms, notwithstanding the fact that
certain Investors may nonetheless, by agreement with the Company, purchase securities in such transaction); provided, that in the event that (x) the right of first offer in Section 4 is waived with respect to any issuance of
New Securities and (y) one or more of the Major Investors that consented to such waiver (each, a “Waiving Major Investor”) nevertheless purchases any such New Securities, each Major Investor that is not a Waiving Major
Investor and did not so purchase shall be entitled to purchase their Pro Rata Amount in such offering (or, if applicable, such lesser amount corresponding to the proportionate amount of New Securities purchased by the Waiving Major Investor
purchasing the largest portion of such Waiving Major Investor’s Pro Rata Amount), (b) Subsection 3.3, the approval rights of the Series C Director under Section 5, and clause (a) and
(b) of this Section 6.6 shall not be amended, modified or waived without the written consent of the holders of a majority of the shares of Series C Preferred Stock then outstanding,
(c) Subsections 3.1 and 3.2, Section 4 and any other section of this Agreement applicable to the Major Investors (including this clause (c) of this Subsection 6.6) may not be

  
 24 

 
amended, modified, terminated or waived without the written consent of the holders of at least a majority of the Registrable Securities then outstanding and held by the Major Investors.
Notwithstanding the foregoing, Schedule A hereto may be amended by the Company from time to time to add transferees of any Registrable Securities in compliance with the terms of this Agreement without the consent of the other parties;
and Schedule A hereto may also be amended by the Company after the date of this Agreement without the consent of the other parties to add information regarding any additional Investor who becomes a party to this Agreement in accordance
with Subsection 6.9. The Company shall give prompt notice of any amendment, modification or termination hereof or waiver hereunder to any party hereto that did not consent in writing to such amendment, modification, termination, or
waiver. Any amendment, modification, termination, or waiver effected in accordance with this Subsection 6.6 shall be binding on all parties hereto, regardless of whether any such party has consented thereto. No waivers of or exceptions
to any term, condition, or provision of this Agreement, in any one or more instances, shall be deemed to be or construed as a further or continuing waiver of any such term, condition, or provision. Notwithstanding the foregoing,
Section 5.7 shall not be amended without the written approval of Sands Capital Venture Fund II, L.P. 

6.7    Severability. In case any one or more of the provisions contained in this Agreement is for any reason held
to be invalid, illegal or unenforceable in any respect, such invalidity, illegality, or unenforceability shall not affect any other provision of this Agreement, and such invalid, illegal, or unenforceable provision shall be reformed and construed so
that it will be valid, legal, and enforceable to the maximum extent permitted by law. 
 6.8    Aggregation of
Stock. All shares of Registrable Securities held or acquired by Affiliates shall be aggregated together for the purpose of determining the availability of any rights under this Agreement and such Affiliated persons may apportion such rights as
among themselves in any manner they deem appropriate. 
 6.9    Additional Investors. Notwithstanding anything to
the contrary contained herein, if the Company issues additional shares of the Company’s Series C Preferred Stock after the date hereof, whether pursuant to the Purchase Agreement or otherwise, any purchaser of such shares of
Series C Preferred Stock may become a party to this Agreement by executing and delivering an additional counterpart signature page to this Agreement, and thereafter shall be deemed an “Investor” for all purposes hereunder. No
action or consent by the Investors shall be required for such joinder to this Agreement by such additional Investor, so long as such additional Investor has agreed in writing to be bound by all of the obligations as an “Investor”
hereunder. 
 6.10    Entire Agreement. This Agreement (including any Schedules and Exhibits hereto) constitutes
the full and entire understanding and agreement among the parties with respect to the subject matter hereof, and any other written or oral agreement relating to the subject matter hereof existing between the parties is expressly canceled. Upon the
effectiveness of this Agreement, the Prior Agreement shall be deemed amended and restated and superseded and replaced in its entirety by this Agreement, and shall be of no further force or effect. 

6.11    Dispute Resolution. The parties (a) hereby irrevocably and unconditionally submit to the jurisdiction
of the state courts of the State of Delaware and to the jurisdiction of the United States District Court for the District of District of Delaware for the purpose of any suit, 

  
 25 

 
action or other proceeding arising out of or based upon this Agreement, (b) agree not to commence any suit, action or other proceeding arising out of or based upon this Agreement except in
the state courts of the State of Delaware or the United States District Court for the District of Delaware, and (c) hereby waive, and agree not to assert, by way of motion, as a defense, or otherwise, in any such suit, action or
proceeding, any claim that it is not subject personally to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment or execution, that the suit, action or proceeding is brought in an inconvenient forum, that
the venue of the suit, action or proceeding is improper or that this Agreement or the subject matter hereof may not be enforced in or by such court. 

WAIVER OF JURY TRIAL: EACH PARTY HEREBY WAIVES ITS RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT, THE
OTHER TRANSACTION DOCUMENTS, THE SECURITIES OR THE SUBJECT MATTER HEREOF OR THEREOF. THE SCOPE OF THIS WAIVER IS INTENDED TO BE ALL-ENCOMPASSING OF ANY AND ALL DISPUTES THAT MAY BE FILED IN ANY COURT AND THAT
RELATE TO THE SUBJECT MATTER OF THIS TRANSACTION, INCLUDING, WITHOUT LIMITATION, CONTRACT CLAIMS, TORT CLAIMS (INCLUDING NEGLIGENCE), BREACH OF DUTY CLAIMS, AND ALL OTHER COMMON LAW AND STATUTORY CLAIMS. THIS SECTION HAS BEEN FULLY DISCUSSED BY EACH
OF THE PARTIES HERETO AND THESE PROVISIONS WILL NOT BE SUBJECT TO ANY EXCEPTIONS. EACH PARTY HERETO HEREBY FURTHER WARRANTS AND REPRESENTS THAT SUCH PARTY HAS REVIEWED THIS WAIVER WITH ITS LEGAL COUNSEL, AND THAT SUCH PARTY KNOWINGLY AND VOLUNTARILY
WAIVES ITS JURY TRIAL RIGHTS FOLLOWING CONSULTATION WITH LEGAL COUNSEL. 
 The prevailing party shall be entitled to reasonable attorney’s fees, costs,
and necessary disbursements in addition to any other relief to which such party may be entitled. Each of the parties to this Agreement consents to personal jurisdiction for any equitable action sought in the U.S. District Court for the District of
Delaware or any court of the State of Delaware having subject matter jurisdiction. 
 6.12    Delays or
Omissions. No delay or omission to exercise any right, power, or remedy accruing to any party under this Agreement, upon any breach or default of any other party under this Agreement, shall impair any such right, power, or remedy of such
nonbreaching or nondefaulting party, nor shall it be construed to be a waiver of or acquiescence to any such breach or default, or to any similar breach or default thereafter occurring, nor shall any waiver of any single breach or default be deemed
a waiver of any other breach or default theretofore or thereafter occurring. All remedies, whether under this Agreement or by law or otherwise afforded to any party, shall be cumulative and not alternative.
