that transaction. Notwithstanding the foregoing, a transaction will not constitute an Acquisition (i) unless the transaction qualifies as a change in control event within the meaning of Code Section 409A; or (ii) if its primary

 3. Term of the Plan 

Unless the Plan shall have been earlier terminated by the Board, Awards may be granted under this Plan at any time in the period commencing on
the date of approval of the Plan by the Board and ending immediately prior to the tenth anniversary of the earlier of the adoption of the Plan by the Board or approval of the Plan by the Company’s stockholders. Awards granted pursuant to the
Plan within that period shall not expire solely by reason of the termination of the Plan. Awards of Incentive Options granted prior to stockholder approval of the Plan are expressly conditioned upon such approval, but in the event of the failure of
the stockholders to approve the Plan shall thereafter and for all purposes be deemed to constitute Nonstatutory Options. 
 4. Stock Subject to the Plan

 At no time shall the number of shares of Common Stock issued pursuant to or subject to outstanding Awards granted under the Plan
exceed                 shares of Common Stock. For purposes of applying the foregoing limitation, if any Option expires, terminates, or is cancelled for any reason
without having been exercised in full, or if any Award of Restricted Stock or Restricted Stock Units is forfeited by the recipient, the shares not purchased by the Optionee or forfeited by the recipient shall again be available for Awards to be
granted under the Plan. Shares of Common Stock issued pursuant to the Plan may be either authorized but unissued shares or shares held by the Company in its treasury. 

5. Administration 
 The Plan shall be
administered by the Committee; provided, however, that at any time and on any one or more occasions the Board may itself exercise any of the powers and responsibilities assigned the Committee under the Plan and when so acting shall have the
benefit of all of the provisions of the Plan pertaining to the Committee’s exercise of its authorities hereunder; and provided further, however, that the Committee may delegate to an executive officer or officers the authority to
grant Awards hereunder to employees who are not officers, and to consultants, in accordance with such guidelines as the Committee shall set forth at any time or from time to time. Subject to the provisions of the Plan, the Committee shall have
complete authority, in its discretion, to make or to select the manner of making all determinations with respect to each Award to be granted by the Company under the Plan including the employee, consultant or director to receive the Award and the
form of Award. In making such determinations, the Committee may take into account the nature of the services rendered by the respective employees, consultants, and directors, their present and potential contributions to the success of the Company
and its Affiliates, and such other factors as the Committee in its discretion shall deem relevant. The Committee shall have 

  
 -4- 

 
complete authority, in its discretion, to institute and determine the terms and conditions of an Exchange Program. Subject to the provisions of the Plan, the Committee shall also have complete
authority to interpret the Plan, to prescribe, amend and rescind rules and regulations relating to it, to determine the terms and provisions of the respective Award Agreements (which need not be identical), and to make all other determinations
necessary or advisable for the administration of the Plan. The Committee’s determinations made in good faith on matters referred to in the Plan shall be final, binding and conclusive on all persons having or claiming any interest under the Plan
or an Award made pursuant to hereto. 
 6. Authorization and Eligibility 

The Committee may grant from time to time and at any time prior to the termination of the Plan one or more Awards, either alone or in
combination with any other Awards, to any employee of or consultant to one or more of the Company and its Affiliates or to any non-employee member of the Board or of any board of directors (or similar
governing authority) of any Affiliate. However, only employees of the Company, and of any parent or subsidiary corporations of the Company, as defined in Sections 424(e) and (f), respectively, of the Code, shall be eligible for the grant of an
Incentive Option. 
 Each grant of an Award shall be subject to all applicable terms and conditions of the Plan (including but not limited
to any specific terms and conditions applicable to that type of Award set out in the following Section), and such other terms and conditions, not inconsistent with the terms of the Plan, as the Committee may prescribe. Without limiting the
foregoing, the Committee shall be entitled to condition the exercise of any Options, or the grant of Restricted Stock or settlement of Restricted Stock Units, upon the contemporaneous execution and delivery by the Participant of an instrument of
accession to each of the Stockholder Agreement. No prospective Participant shall have any rights with respect to an Award, unless and until such Participant has executed an agreement evidencing the Award, delivered a fully executed copy thereof to
the Company, and otherwise complied with the applicable terms and conditions of such Award. 
 7. Specific Terms of Awards 

7.1 Options. 
 (a) Date
of Grant. The granting of an Option shall take place at the time specified in the Award Agreement. Only if expressly so provided in the applicable Award Agreement shall the Grant Date be the date on which the Award Agreement shall have been duly
executed and delivered by the Company and the Optionee. 
 (b) Exercise Price. The price at which shares of Common Stock may be
acquired under each Incentive Option shall be not less than 100% of the Market Value of Common Stock on the Grant Date, or not less than 110% of the Market Value of Common Stock on the Grant Date if the Optionee is a Ten Percent Owner. The price at
which shares may be acquired under each Nonstatutory Option shall not be so limited solely by reason of this Section. 

  
 -5- 

 (c) Option Period. No Incentive Option may be exercised on or after the tenth
anniversary of the Grant Date, or on or after the fifth anniversary of the Grant Date if the Optionee is a Ten Percent Owner. The Option period under each Nonstatutory Option shall not be so limited solely by reason of this Section. 

(d) Exercisability. An Option may be immediately exercisable or become exercisable in such installments, cumulative or non-cumulative, as the Committee may determine. In the case of an Option not otherwise immediately exercisable in full, the Committee may Accelerate such Option in whole or in part at any time; provided, however,
that in the case of an Incentive Option, any such Acceleration of the Option would not cause the Option to fail to comply with the provisions of Section 422 of the Code or the Optionee consents to the Acceleration. 

(e) Termination of Association with the Company. Unless the Committee or any Award Agreement shall provide otherwise with respect to any
Option, if the Optionee’s employment or other association with the Company and its Affiliates ends for any reason other than death or disability (as determined by the Board), including because of the Optionee’s employer ceasing to be an
Affiliate, any outstanding Option of the Optionee shall cease to be exercisable in any respect not later than 90 days following that event and, for the period it remains exercisable following that event, shall be exercisable only to the extent
exercisable at the date of that event. Unless the Committee shall provide otherwise with respect to any Option, if the Optionee’s employment or other association with the Company and its Affiliates ends for death or disability, any outstanding
Option of the Optionee shall cease to be exercisable in any respect not later than 365 days following that event and, for the period it remains exercisable following that event, shall be exercisable only to the extent exercisable at the date of
that event. Military or sick leave or other bona fide leave shall not be deemed a termination of employment or other association, provided that it does not exceed the longer of ninety (90) days or the period during which the absent
Optionee’s reemployment rights, if any, are guaranteed by statute or by contract. Notwithstanding and in addition to the forgoing, if the Optionee’s employment with the Company is terminated due to disability and the Optionee’s death
occurs prior to the first anniversary of such termination, the period in which the Options may be exercised by the Optionee shall be extended for an additional three hundred sixty five (365) days following the date of the Optionee’s death.

 (f) Transferability. Except as otherwise provided in this subsection (f), Options shall not be transferable, and no Option or
interest therein may be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated, other than by will or by the laws of descent and distribution. All of a Participant’s rights in any Option may be exercised during the life of
the Participant only by the Participant or the Participant’s legal representative. However, the Committee may, at or after the grant of a Nonstatutory Option, provide that such Option may be transferred by the recipient to a family member;
provided, however, that any such transfer is without payment of any consideration whatsoever and that no transfer of an Option shall be valid unless first approved by the Committee, acting in its sole discretion. For this purpose,
“family member” means any child, stepchild, grandchild, parent, stepparent, spouse, former spouse, sibling, niece, nephew, mother-in-law, father-in-law, son-in-law,
daughter-in-law, brother-in-law, or sister-in-law, including adoptive relationships, any person sharing the employee’s household (other than a tenant or employee), a trust in which the foregoing persons have more than fifty (50)
percent of the beneficial interests, a foundation in which the foregoing persons (or the Participant) control the management of assets, and any other entity in which these persons (or the Participant) own more than fifty (50) percent of the
voting interests. 

  
 -6- 

 (g) Method of Exercise. An Option may be exercised by the Optionee giving written
notice, in the manner provided in Section 14, specifying the number of shares with respect to which the Option is then being exercised. The notice shall be accompanied by payment in the form of cash or check payable to the order of the Company
in an amount equal to the exercise price of the shares to be purchased or, if the Committee had so authorized on the grant of an Incentive Option or on or after grant of an Nonstatutory Option (and subject to such conditions, if any, as the
Committee may deem necessary to avoid adverse accounting effects to the Company) by delivery to the Company of shares of Common Stock having a Market Value equal to the exercise price of the shares to be purchased. At the sole option of the Board,
payment of any exercise price may also be made through and under the terms and conditions of any cashless exercise program authorized by the Company. Receipt by the Company of such notice and payment in any authorized or combination of authorized
means shall constitute the exercise of the Option. Within thirty (30) days thereafter but subject to the remaining provisions of the Plan, the Company shall deliver or cause to be delivered to the Optionee or his agent a certificate or
certificates for the number of shares then being purchased. Such shares shall be fully paid and nonassessable. 
 (h) Limit on Incentive
Option Characterization. An Incentive Option shall be considered to be an Incentive Option only to the extent that the number of shares of Common Stock for which the Option first becomes exercisable in a calendar year do not have an aggregate
Market Value (as of the date of the grant of the Option) in excess of the “current limit”. The current limit for any Optionee for any calendar year shall be $100,000 minus the aggregate Market Value at the date of grant of the
number of shares of Common Stock available for purchase for the first time in the same year under each other Incentive Option previously granted to the Optionee under the Plan, and under each other incentive stock option previously granted to the
Optionee under any other incentive stock option plan of the Company and its Affiliates, after December 31, 1986. Any shares of Common Stock which would cause the foregoing limit to be violated shall be deemed to have been granted under a
separate Nonstatutory Option, otherwise identical in its terms to those of the Incentive Option. 
 (i) Notification of Disposition.
Each person exercising any Incentive Option granted under the Plan shall be deemed to have covenanted with the Company to report to the Company any disposition of such shares prior to the expiration of the holding periods specified by
Section 422(a)(1) of the Code and, if and to the extent that the realization of income in such a disposition imposes upon the Company federal, state, local or other withholding tax requirements, or any such withholding is required to secure for
the Company an otherwise available tax deduction, to remit to the Company an amount in cash sufficient to satisfy those requirements. 
 (j)
Rights Pending Exercise. No person holding an Option shall be deemed for any purpose to be a stockholder of the Company with respect to any of the shares of Stock issuable pursuant to his Option, except to the extent that the Option shall
have been exercised with respect thereto and, in addition, a certificate shall have been issued therefor and delivered to such holder or his agent.

 7.2 Restricted Stock. 

(a) Purchase Price. Shares of Restricted Stock shall be issued under the Plan for such consideration, in cash, other property or
services, or any combination thereof, as is determined by the Committee. 
 (b) Issuance of Certificates. Each Participant receiving a
Restricted Stock Award, subject to subsection (c) below, shall be issued a stock certificate in respect of such shares of Restricted Stock. Such certificate shall be registered in the name of such Participant, and, if applicable, shall bear an
appropriate legend referring to the terms, conditions, and restrictions applicable to such Award substantially in the following form: 
 The
transferability of this certificate and the shares represented by this certificate are subject to the terms and conditions of the Thorne HealthTech, Inc. 2010 Equity Incentive Plan and an Award Agreement entered into by the registered owner and
Thorne HealthTech, Inc. Copies of such Plan and Agreement are on file in the offices of Thorne HealthTech, Inc. 
 (c) Escrow of
Shares. The Committee may require that the stock certificates evidencing shares of Restricted Stock be held in custody by a designated escrow agent (which may but need not be the Company) until the restrictions thereon shall have lapsed, and
that the Participant deliver a stock power, endorsed in blank, relating to the Stock covered by such Award. 
 (d) Restrictions and
Restriction Period. During the Restriction Period applicable to shares of Restricted Stock, such shares shall be subject to limitations on transferability and a Risk of Forfeiture arising on the basis of such conditions related to the
performance of services, Company or Affiliate performance or otherwise as the Committee may determine and provide for in the applicable Award Agreement. Any such Risk of Forfeiture may be waived or terminated, or the Restriction Period shortened, at
any time by the Committee on such basis as it deems appropriate. 
 (e) Rights Pending Lapse of Risk of Forfeiture or Forfeiture of
Award. Except as otherwise provided in the Plan or the applicable Award Agreement, at all times prior to lapse of any Risk of Forfeiture applicable to, or forfeiture of, an Award of Restricted Stock, the Participant shall have all of the rights
of a stockholder of the Company, including the right to vote, and the right to receive any dividends with respect to, the shares of Restricted Stock. The Committee, as determined at the time of Award, may permit or require the payment of cash
dividends to be deferred and, if the Committee so determines, reinvested in additional Restricted Stock to the extent shares are available under Section 4. 

(f) Termination of Association with the Company. Unless the Committee shall provide otherwise for any Award of Restricted Stock, upon
termination of a Participant’s employment or other association with the Company and its Affiliates for any reason during the Restriction Period, including because of the Participant’s employer ceasing to be an Affiliate during the
Restriction Period, all shares of Restricted Stock still subject to Risk of Forfeiture shall be forfeited or otherwise subject to return to or repurchase by the Company on the terms specified in the Award Agreement; provided, however, that
military or sick leave or other bona fide leave shall not be deemed a termination of employment or other association, if it does not exceed the longer of ninety (90) days or the period during which the absent Participant’s reemployment
rights, 

  
 -8- 

 
if any, are guaranteed by statute or by contract and, provided, further, that in the event that the Participant’s employment or other association with the Company terminates as a
result of the death or disability (as determined by the Board) of Participant, all further Risk of Forfeiture of any shares of Restricted Stock shall lapse. 

(g) Lapse of Restrictions. If and when the Restriction Period expires without a prior forfeiture of the Restricted Stock, the
certificates for such shares shall be delivered to the Participant promptly if not theretofore so delivered. 
 7.3 Stock Grants.
Stock Grants shall be awarded solely in recognition of significant contributions to the success of the Company or its Affiliates, in lieu of compensation otherwise already due and in such other limited circumstances as the Committee deems
appropriate. Stock Grants shall be made without forfeiture conditions of any kind. 
 7.4 Awards to Participants Outside the United
States. The Committee may modify the terms of any Award under the Plan granted to a Participant who is, at the time of grant or during the term of the Award, resident or primarily employed outside of the United States in any manner deemed by the
Committee to be necessary or appropriate in order that the Award shall conform to laws, regulations, and customs of the country in which the Participant is then resident or primarily employed, or so that the value and other benefits of the Award to
the Participant, as affected by foreign tax laws and other restrictions applicable as a result of the Participant’s residence or employment abroad, shall be comparable to the value of such an Award to a Participant who is resident or primarily
employed in the United States. An Award may be modified under this Section 7.4 in a manner that is inconsistent with the express terms of the Plan, so long as such modifications will not contravene any applicable law or regulation. 

7.5 Restricted Stock Units. 

(a) Grant. Restricted Stock Units may be granted at any time and from time to time as determined by the Committee. After the Committee
determines that it will grant Restricted Stock Units, it will advise the Participant in an Award Agreement of the terms, conditions, and restrictions related to the grant, including the number of Restricted Stock Units. 

(b) Vesting Criteria and Other Terms. The Committee will set vesting criteria in its discretion, which, depending on the extent to which
the criteria are met, will determine the number of Restricted Stock Units that will be paid out to the Participant. The Committee may set vesting criteria based upon the achievement of Company-wide, business unit, or individual goals (including, but
not limited to, continued employment or service), or any other basis determined by the Committee in its discretion. 
 (c) Earning
Restricted Stock Units. Upon meeting the applicable vesting criteria, the Participant will be entitled to receive a payout as determined by the Committee. Notwithstanding the foregoing, at any time after the grant of Restricted Stock Units, the
Committee, in its sole discretion, may reduce or waive any vesting criteria that must be met to receive a payout. 
 (d) Form and Timing
of Payment. Payment of earned Restricted Stock Units will be made as soon as practicable after the date(s) determined by the Committee and set forth in the Award Agreement. The Committee, in its sole discretion, may settle earned Restricted
Stock Units in cash, Shares, or a combination of both. 

  
 -9- 

 (e) Cancellation. On the date set forth in the Award Agreement, all unearned
Restricted Stock Units will be forfeited to the Company. 
 8. Adjustment Provisions 

8.1 Adjustment for Corporate Actions. In the event that any dividend or other distribution (whether in the form of cash, shares of
Common Stock, other securities, or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off,
combination, repurchase, or exchange of shares of Common Stock or other securities of the Company, or other change in the corporate structure of the Company affecting the shares of Common Stock occurs, the Committee, in order to prevent diminution
or enlargement of the benefits or potential benefits intended to be made available under the Plan, will adjust the number and class of shares of stock that may be delivered under the Plan and/or the number, class, and price of shares of stock
covered by each outstanding Award. Further, the Committee will make such adjustments to an Award as required by Section 25102(o) of the California Corporations Code to the extent the Company is relying upon the exemption afforded thereby with
respect to the Award. 
 8.2 Treatment in Acquisitions. Subject to any provisions of then outstanding Awards granting greater rights
to the holders thereof, in the event of an Acquisition (a) any then outstanding Options shall Accelerate in full if not assumed by the acquiring entity or replaced by comparable options to purchase shares of the capital stock of the successor
or acquiring entity or parent thereof, and to the extent not assumed or replaced on the Acquisition shall then (or after a reasonable period following the Acquisition, as determined by the Committee) terminate to the extent not exercised,
(b) any then outstanding Restricted Stock shall Accelerate in full if the Company’s rights to reacquire such shares of Restricted Stock on occurrence of the applicable Risk of Forfeiture with respect to those shares are not assigned to the
acquiring entity, and (c) and any then outstanding Restricted Stock Units shall Accelerate in full if not assumed or replaced by comparable restricted stock units to receive shares of the capital stock of the successor or acquiring entity or
parent thereof. As to any one or more outstanding Options, shares of Restricted Stock or Restricted Stock Units which are not otherwise Accelerated in full by reason of such Acquisition, the Committee may also, either in advance of an Acquisition or
at the time thereof and upon such terms as it may deem appropriate, provide for the Acceleration of such outstanding Options , Restricted Stock and Restricted Stock Units in the event that the employment of the Participants should subsequently
terminate following the Acquisition. Each outstanding Option that is assumed in connection with an Acquisition, or is otherwise to continue in effect subsequent to the Acquisition, will be appropriately adjusted, immediately after the Acquisition,
as to the number and class of securities and the price at which it may be exercised in accordance with Section 8.1. In addition to or in lieu of the foregoing, with respect to outstanding Options, in the event of an Acquisition the Board may
provide that one or more Options then outstanding shall become immediately exercisable in full and shall be terminated in exchange for a cash payment equal to the excess of the fair market value (as determined by the Board in its sole discretion) of
the shares subject to such Options over the exercise price thereof. 

  
 -10- 

 8.3 Dissolution or Liquidation. Upon dissolution or liquidation of the Company, other
than as part of an Acquisition or similar transaction, each outstanding Award shall terminate, but, with respect to then outstanding Options, the applicable Optionees (if at the time in the employ of or otherwise associated with the Company or any
of its Affiliates) shall have the right, immediately prior to the dissolution or liquidation, to exercise the Options to the extent exercisable on the date of dissolution or liquidation. 

8.4 Related Matters. Any adjustment in Awards made pursuant to this Section 8 shall be determined and made, if at all, by the
Committee and shall include any correlative modification of terms, including of Option exercise prices, rates of vesting or exercisability, Risks of Forfeiture and applicable repurchase prices for Restricted Stock, which the Committee may deem
necessary or appropriate so as to ensure the rights of the Participants in their respective Awards are not substantially diminished nor enlarged as a result of the adjustment and corporate action other than as expressly contemplated in this
Section 8. No fraction of a share shall be purchasable or deliverable upon exercise, but in the event any adjustment hereunder of the number of shares covered by an Award shall cause such number to include a fraction of a share, such number of
shares shall be adjusted to the nearest smaller whole number of shares. No adjustment of an Option exercise price per share pursuant to this Section 8 shall result in an exercise price which is less than the par value of the Stock. 

9. Settlement of Awards 
 9.1 Violation
of Law. Notwithstanding any other provision of the Plan or the relevant Award Agreement, if, at any time, in the reasonable opinion of the Company, the issuance of shares of Common Stock covered by an Award may constitute a violation of law,
then the Company may delay such issuance and the delivery of a certificate for such shares until (i) approval shall have been obtained from such governmental agencies, other than the Securities and Exchange Commission, as may be required under
any applicable law, rule, or regulation, and (ii) in the case where such issuance would constitute a violation of a law administered by or a regulation of the Securities and Exchange Commission, one of the following conditions shall have been
satisfied: 
 (a) the shares are at the time of the issue of such shares effectively registered under the Securities Act of 1933; or 

(b) the Company shall have determined, on such basis as it deems appropriate (including an opinion of counsel in form and substance
satisfactory to the Company) that the sale, transfer, assignment, pledge, encumbrance or other disposition of such shares or such beneficial interest, as the case may be, does not require registration under the Securities Act of 1933, as amended or
any applicable State securities laws. 
 The Company shall make all reasonable efforts to bring about the occurrence of said events. 

9.2 Corporate Restrictions on Rights in Stock. Any Stock to be issued pursuant to Awards granted under the Plan shall be subject to all
restrictions upon the transfer thereof which may be now or hereafter imposed by the charter, certificate or articles, and by-laws, of the Company. Whenever Stock is to be issued pursuant to an Award, if the
Committee so directs at or after grant, the Company shall be under no obligation to issue such shares until such time, if 

  
 -11- 

 
ever, as the recipient of the Award (and any person who exercises any Option, in whole or in part), shall have become a party to and bound by the Stockholder Agreement, if any. In the event of
any conflict between the provisions of this Plan and the provisions of the Stockholder Agreement, the provisions of the Stockholder Agreement shall control except as required to fulfill the intention that this Plan constitute an incentive stock
option plan within the meaning of Section 422 of the Code, but insofar as possible the provisions of the Plan and such Agreement shall be construed so as to give full force and effect to all such provisions. 

9.3 Investment Representations. The Company shall be under no obligation to issue any shares covered by any Award unless the shares to
be issued pursuant to Awards granted under the Plan have been effectively registered under the Securities Act of 1933, as amended, or the Participant shall have made such written representations to the Company (upon which the Company believes it may
reasonably rely) as the Company may deem necessary or appropriate for purposes of confirming that the issuance of such shares will be exempt from the registration requirements of that Act and any applicable state securities laws and otherwise in
compliance with all applicable laws, rules and regulations, including but not limited to that the Participant is acquiring the shares for his or her own account for the purpose of investment and not with a view to, or for sale in connection with,
the distribution of any such shares. 
 9.4 Registration. If the Company shall deem it necessary or desirable to register under the
Securities Act of 1933, as amended or other applicable statutes any shares of Stock issued or to be issued pursuant to Awards granted under the Plan, or to qualify any such shares of Stock for exemption from the Securities Act of 1933, as amended or
other applicable statutes, then the Company shall take such action at its own expense. The Company may require from each recipient of an Award, or each holder of shares of Stock acquired pursuant to the Plan, such information in writing for use in
any registration statement, prospectus, preliminary prospectus or offering circular as is reasonably necessary for that purpose and may require reasonable indemnity to the Company and its officers and directors from that holder against all losses,
claims, damage and liabilities arising from use of the information so furnished and caused by any untrue statement of any material fact therein or caused by the omission to state a material fact required to be stated therein or necessary to make the
statements therein not misleading in the light of the circumstances under which they were made. In addition, the Company may require of any such person that he or she agree that, without the prior written consent of the Company or the managing
underwriter in any public offering of shares of Stock, he or she will not sell, make any short sale of, loan, grant any option for the purchase of, pledge or otherwise encumber, or otherwise dispose of, any shares of Common Stock during the
180 day period commencing on the effective date of the registration statement relating to the underwritten public offering of securities. Without limiting the generality of the foregoing provisions of this Section 9.4, if in connection
with any underwritten public offering of securities of the Company the managing underwriter of such offering requires that the Company’s directors and officers enter into a lock-up agreement containing
provisions that are more restrictive than the provisions set forth in the preceding sentence, then (a) each holder of shares of Stock acquired pursuant to the Plan (regardless of whether such person has complied or complies with the provisions
of clause (b) below) shall be bound by, and shall be deemed to have agreed to, the same lock-up terms as those to which the Company’s directors and officers are required to adhere; and (b) at
the request of the Company or such managing underwriter, each such person shall execute and deliver a lock-up agreement in form and substance equivalent to that which is required to be executed by the
Company’s directors and officers. 

  
 -12- 

 9.5 Placement of Legends; Stop Orders etc. Each share of Common Stock to be
issued pursuant to Awards granted under the Plan may bear a reference to the investment representation made in accordance with Section 9.3 in addition to any other applicable restriction under the Plan, the terms of the Award and if applicable
under the Stockholder Agreement and to the fact that no registration statement has been filed with the Securities and Exchange Commission in respect to such shares of Common Stock. All certificates for shares of Common Stock or other securities
delivered under the Plan shall be subject to such stock transfer orders and other restrictions as the Committee may deem advisable under the rules, regulations, and other requirements of any stock exchange upon which the Common Stock is then listed,
and any applicable federal or state securities law, and the Committee may cause a legend or legends to be put on any such certificates to make appropriate reference to such restrictions. 

9.6 Tax Withholding. Prior to the delivery of any shares of Common Stock or cash pursuant to an Award (or exercise thereof), the Company
will have the power and the right to deduct or withhold, or require a Participant to remit to the Company, an amount sufficient to satisfy federal, state, local, foreign or other taxes (including the Participant’s FICA obligation) required to
be withheld with respect to such Award (or exercise thereof). The Committee, in its sole discretion and pursuant to such procedures as it may specify from time to time, may permit a Participant to satisfy such tax withholding obligation, in whole or
in part by such methods as the Committee shall determine, including, without limitation, (i) paying cash, (ii) electing to have the Company withhold otherwise deliverable shares of Common Stock having a fair market value equal to the
minimum statutory amount required to be withheld or such greater amount as the Committee may determine if such amount would not have adverse accounting consequences, as the Committee determines in its sole discretion, (iii) delivering to the
Company already-owned shares of Common Stock having a fair market value equal to the statutory amount required to be withheld or such greater amount as the Committee may determine, in each case, provided the delivery of such shares will not result
in any adverse accounting consequences, as the Committee determines in its sole discretion, (iv) selling a sufficient number of shares of Common Stock otherwise deliverable to the Participant through such means as the Committee may determine in
its sole discretion (whether through a broker or otherwise) equal to the amount required to be withheld, or (v) any combination of the foregoing methods of payment. The amount of the withholding requirement will be deemed to include any amount
which the Committee agrees may be withheld at the time the election is made, not to exceed the amount determined by using the maximum federal, state or local marginal income tax rates applicable to the Participant with respect to the Award on the
date that the amount of tax to be withheld is to be determined or such greater amount as the Committee may determine if such amount would not have adverse accounting consequences, as the Committee determines in its sole discretion. The fair market
value of the shares of Common Stock to be withheld or delivered will be determined as of the date that the taxes are required to be withheld. 

9.7 Compliance With Code Section 409A. Awards will be designed and operated in such a manner that they are either
exempt from the application of, or comply with, the requirements of Code Section 409A such that the grant, payment, settlement or deferral will not be subject to the additional tax or interest applicable under Code Section 409A, except as
otherwise determined in the sole discretion of the Committee. The Plan and each Award Agreement under the Plan is intended to meet the requirements of Code Section 409A and will be construed and interpreted in accordance with such intent,
except as otherwise determined in the sole discretion of the 

  
 -13- 

 
Committee. To the extent that an Award or payment, or the settlement or deferral thereof, is subject to Code Section 409A the Award will be granted, paid, settled or deferred in a manner
that will meet the requirements of Code Section 409A, such that the grant, payment, settlement or deferral will not be subject to the additional tax or interest applicable under Code Section 409A. In no event will the Company or any
Affiliate have any obligation under the terms of this Plan to reimburse a Participant for any taxes or other costs that may be imposed on Participant as a result of Section 409A. 

10. Reservation of Stock 
 The Company
shall at all times during the term of the Plan and any outstanding Awards granted hereunder reserve or otherwise keep available such number of shares of Stock as will be sufficient to satisfy the requirements of the Plan (if then in effect) and the
Awards and shall pay all fees and expenses necessarily incurred by the Company in connection therewith. 
 11. No Special Employment or Other Rights

 Nothing contained in the Plan or in any Award Agreement shall confer upon any recipient of an Award any right with respect to the
continuation of his or her employment or other association with the Company (or any Affiliate), or interfere in any way with the right of the Company (or any Affiliate), subject to the terms of any separate employment or consulting agreement or
provision of law or corporate charter, certificate or articles, or by-laws, to the contrary, at any time to terminate such employment or consulting agreement or to increase or decrease, or otherwise adjust,
the other terms and conditions of the recipient’s employment or other association with the Company and its Affiliates. 
 12. Nonexclusivity of the
Plan 
 Neither the adoption of the Plan by the Board nor the submission of the Plan to the stockholders of the Company shall be
construed as creating any limitations on the power of the Board to adopt such other incentive arrangements as it may deem desirable, including without limitation, the granting of stock options, restricted stock and restricted stock units other than
under the Plan, and such arrangements may be either applicable generally or only in specific cases. 
 13. Termination and Amendment of the Plan 

The Board may at any time terminate the Plan or make such modifications of the Plan as it shall deem advisable. Unless the Board otherwise
expressly provides, no amendment of the Plan shall affect the terms of any Award outstanding on the date of such amendment. In any case, no termination or amendment of the Plan may, without the consent of any recipient of an Award granted hereunder,
adversely affect the rights of the recipient under such Award. 
 The Committee may amend the terms of any Award theretofore granted,
prospectively or retroactively, provided that the Award as amended is consistent with the terms of the Plan, but no such amendment shall impair the rights of the recipient of such Award without his or her consent. 

  
 -14- 

 14. Notices and Other Communications 

Any notice, demand, request or other communication hereunder to any party shall be deemed to be sufficient if contained in a written instrument
delivered in person or duly sent by first class registered, certified or overnight mail, postage prepaid, or telecopied with a confirmation copy by regular, certified or overnight mail, addressed or telecopied, as the case may be, (i) if to the
recipient of an Award, at his or her residence address last filed with the Company and (ii) if to the Company, at its principal place of business, addressed to the attention of its Treasurer, or to such other address or telecopier number, as
the case may be, as the addressee may have designated by notice to the addressor. All such notices, requests, demands and other communications shall be deemed to have been received: (i) in the case of personal delivery, on the date of such
delivery; (ii) in the case of mailing, when received by the addressee; and (iii) in the case of facsimile transmission, when confirmed by facsimile machine report. 

15. Governing Law 
 The Plan and all Award
Agreements and actions taken thereunder shall be governed, interpreted and enforced in accordance with the laws of the State of Delaware, without regard to the conflict of laws principles thereof.

	  	«GrantDate»
		
	 Number of Restricted Stock Units:
	  	«Shares»

 Vesting Commencement Date: 

The first date following the expiration of the Lock-Up Period (as defined in Section 5 of Part II
of the Award Agreement) following an Initial Public Offering (as defined below), subject to Participant continuing to be an employee, director or consultant of the Company or any Affiliate (a “Service Provider”) through such date.
“Initial Public Offering” means the consummation of the first firm commitment underwritten public offering pursuant to an effective registration statement on Form S-1 filed with the Securities and
Exchange Commission covering the offer and sale by the Company of its equity securities, as a result of or following which the Company’s Common Stock shall be publicly held.

Subject to any acceleration provisions contained in the Plan or set forth below, the Restricted Stock Units shall vest in accordance with the
following schedule: 
 Twenty-five percent (25%) of the Restricted Stock Units shall vest on each one year anniversary of the Vesting
Commencement Date, subject to Participant continuing to be a Service Provider through each applicable vesting date. 
 In the event
Participant ceases to be a Service Provider for any or no reason before Participant vests in the Restricted Stock Units, the Restricted Stock Units and Participant’s right to acquire any Shares hereunder will immediately terminate. 

 II. AGREEMENT 

1. Grant of Restricted Stock Units. The Company hereby grants to the individual (“Participant”) named in the Notice of Grant
of Restricted Stock Units in Part I of this Award Agreement (the “Notice of Grant”) under the Plan an Award of Restricted Stock Units, subject to all of the terms and conditions in this Award Agreement and the Plan, which is incorporated
herein by reference. Subject to Section 13 of the Plan, in the event of a conflict between the terms and conditions of the Plan and this Award Agreement, the terms and conditions of the Plan shall prevail. 

2. Company’s Obligation to Pay. Each Restricted Stock Unit represents the right to receive a share of Common Stock (a
“Share”) on the date it vests. Unless and until the Restricted Stock Units will have vested in the manner set forth in Section 4, Participant will have no right to payment of any such Restricted Stock Units. Prior to actual payment of
any vested Restricted Stock Units, such Restricted Stock Unit will represent an unsecured obligation of the Company, payable (if at all) only from the general assets of the Company. 

3. Participant’s Representations. In the event the Shares have not been registered under the Securities Act of 1933, as amended
(the “Securities Act”) at the time the Restricted Stock Units are paid to Participant, Participant shall, if required by the Company, concurrently with the receipt of all or any portion of this Restricted Stock Unit Award, deliver to the
Company his or her Investment Representation Statement in the form attached hereto as Exhibit A. 
 4. Vesting Schedule. Except
as provided in Section 6, and subject to Section 7, the Restricted Stock Units awarded by this Award Agreement will vest in accordance with the vesting schedule set forth in the Notice of Grant, subject to Participant continuing to be a
Service Provider through each applicable vesting date. 
 5. Lock-Up Period. Participant
hereby agrees that Participant shall not 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, lend, or otherwise transfer or dispose
of, directly or indirectly, any Common Stock (or other securities) of the Company or enter into any swap, hedging or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any Common Stock
(or other securities) of the Company held by Participant (other than those included in the registration) for a period specified by the representative of the underwriters of Common Stock (or other securities) of the Company not to exceed one hundred
and eighty (180) days following the effective date of any registration statement of the Company filed under the Securities Act (or such other period as may be requested by the Company or the underwriters to accommodate regulatory restrictions
on (i) the publication or other distribution of research reports and (ii) analyst recommendations and opinions, including, but not limited to, the restrictions contained in NASD Rule 2711(f)(4) or NYSE Rule 472(f)(4), or any
successor provisions or amendments thereto) (such period, the “Lock-Up Period”). 

Participant agrees to execute and deliver such other agreements as may be reasonably requested by the Company or the underwriter which are
consistent with the foregoing or which are necessary to give further effect thereto. In addition, if requested by the Company or the representative of the underwriters of Common Stock (or other securities) of the Company, Participant shall provide,
within ten (10) days of such request, such information as may be required by the Company or such representative in connection with the completion of any public offering of the Company’s securities

  
 2 

 
pursuant to a registration statement filed under the Securities Act. The obligations described in this Section 5 shall not apply to a registration relating solely to employee benefit plans
on Form S-1 or Form S-8 or similar forms that may be promulgated in the future, or a registration relating solely to a Commission Rule 145 transaction on Form S-4 or similar forms that may be promulgated in the future. The Company may impose stop-transfer instructions with respect to the shares of Common Stock (or other securities) subject to the foregoing restriction
until the end of said one hundred and eighty (180) day (or other) period. Participant agrees that any transferee of the Restricted Stock Unit Award or Shares acquired pursuant to the Restricted Stock Unit Award shall be bound by this
Section 5. 
 6. Payment after Vesting. 

(a) General Rule. Subject to Section 10, any Restricted Stock Units that vest will be paid to Participant (or in the event of
Participant’s death, to his or her properly designated beneficiary or estate) in whole Shares. Subject to the provisions of Section 6(b), such vested Restricted Stock Units shall be paid in whole Shares as soon as practicable after
vesting, but in each such case within sixty (60) days following the vesting date. In no event will Participant be permitted, directly or indirectly, to specify the taxable year of payment of any Restricted Stock Units payable under this Award
Agreement. 
 (b) Acceleration. 

(i) Discretionary Acceleration. The Committee, in its discretion, may accelerate the vesting of the balance, or some lesser portion of
the balance, of the unvested Restricted Stock Units at any time, subject to the terms of the Plan. If so accelerated, such Restricted Stock Units will be considered as having vested as of the date specified by the Committee. If Participant is a U.S.
taxpayer, the payment of Shares vesting pursuant to this Section 6(b) shall in all cases be paid at a time or in a manner that is exempt from, or complies with, Section 409A. The prior sentence may be superseded in a future agreement or
amendment to this Award Agreement only by direct and specific reference to such sentence. 
 (ii) Notwithstanding anything in the Plan or
this Award Agreement or any other agreement (whether entered into before, on or after the Date of Grant), if the vesting of the balance, or some lesser portion of the balance, of the Restricted Stock Units is accelerated in connection with
Participant’s termination as a Service Provider (provided that such termination is a “separation from service” within the meaning of Section 409A, as determined by the Company), other than due to Participant’s death, and if
(x) Participant is a U.S. taxpayer and a “specified employee” within the meaning of Section 409A at the time of such termination as a Service Provider and (y) the payment of such accelerated Restricted Stock Units will
result in the imposition of additional tax under Section 409A if paid to Participant on or within the six (6) month period following Participant’s termination as a Service Provider, then the payment of such accelerated Restricted
Stock Units will not be made until the date six (6) months and one (1) day following the date of Participant’s termination as a Service Provider, unless Participant dies following his or her termination as a Service Provider, in which
case, the Restricted Stock Units will be paid in Shares to Participant’s estate as soon as practicable following his or her death. 

  
 3 

 (c) Section 409A. It is the intent of this Award Agreement that it
and all payments and benefits to U.S. taxpayers hereunder be exempt from, or comply with, the requirements of Section 409A so that none of the Restricted Stock Units provided under this Award Agreement or Shares issuable thereunder will be
subject to the additional tax imposed under Section 409A, and any ambiguities herein will be interpreted to be so exempt or so comply. Each payment payable under this Award Agreement is intended to constitute a separate payment for purposes of
Treasury Regulation Section 1.409A-2(b)(2). However, in no event will the Company reimburse Participant, or be otherwise responsible for, any taxes or costs that may be imposed on Participant as a result
of Section 409A. For purposes of this Award Agreement, “Section 409A” means Section 409A of the Code, and any final Treasury Regulations and Internal Revenue Service guidance thereunder, as each may be amended from time to
time. 
 7. Forfeiture Upon Termination as a Service Provider. Notwithstanding any contrary provision of this Award Agreement, if
Participant ceases to be a Service Provider for any or no reason, the then-unvested Restricted Stock Units awarded by this Award Agreement will thereupon be forfeited at no cost to the Company and Participant will have no further rights thereunder.

 8. Tax Consequences. Participant has reviewed with his or her own tax advisors the U.S. federal, state, local and non-U.S. tax consequences of this investment and the transactions contemplated by this Award Agreement. With respect to such matters, Participant relies solely on such advisors and not on any statements or
representations of the Company or any of its agents, written or oral. Participant understands that Participant (and not the Company) shall be responsible for Participant’s own tax liability that may arise as a result of this investment or the
transactions contemplated by this Award Agreement. 
 9. Death of Participant. Any distribution or delivery to be made to Participant
under this Award Agreement will, if Participant is then deceased, be made to Participant’s designated beneficiary, or if no beneficiary survives Participant, the administrator or executor of Participant’s estate. Any such transferee must
furnish the Company with (a) written notice of his or her status as transferee, and (b) evidence satisfactory to the Company to establish the validity of the transfer and compliance with any laws or regulations pertaining to said transfer.

 10. Tax Obligations 

(a) Responsibility for Taxes. Participant acknowledges that, regardless of any action taken by the Company or, if different,
Participant’s employer (the “Employer”), the ultimate liability for any tax and/or social insurance liability obligations and requirements in connection with the Restricted Stock Units, including, without limitation, (i) all
federal, state, and local taxes (including the Participant’s Federal Insurance Contributions Act (FICA) obligation) that are required to be withheld by the Company or the Employer or other payment of
tax-related items related to Participant’s participation in the Plan and legally applicable to Participant, (ii) the Participant’s and, to the extent required by the Company (or Employer), the
Company’s (or Employer’s) fringe benefit tax liability, if any, associated with the grant, vesting, or settlement of the Restricted Stock Units or sale of Shares, and (iii) any other Company (or Employer) taxes the responsibility for
which the Participant has, or has agreed to bear, with respect to the Restricted Stock Units (or settlement thereof or issuance of Shares thereunder) (collectively, the “Tax Obligations”), is and remains Participant’s

  
 4 

 
responsibility and may exceed the amount actually withheld by the Company or the Employer. Participant further acknowledges that the Company and/or the Employer (i) make no representations
or undertakings regarding the treatment of any Tax Obligations in connection with any aspect of the Restricted Stock Units, including, but not limited to, the grant, vesting or settlement of the Restricted Stock Units, the subsequent sale of Shares
acquired pursuant to such settlement and the receipt of any dividends or other distributions, and (ii) do not commit to and are under no obligation to structure the terms of the grant or any aspect of the Restricted Stock Units to reduce or
eliminate Participant’s liability for Tax Obligations or achieve any particular tax result. Further, if Participant is subject to Tax Obligations in more than one jurisdiction between the Date of Grant and the date of any relevant taxable or
tax withholding event, as applicable, Participant acknowledges that the Company and/or the Employer (or former employer, as applicable) may be required to withhold or account for Tax Obligations in more than one jurisdiction. If Participant fails to
make satisfactory arrangements for the payment of any required Tax Obligations hereunder at the time of the applicable taxable event, Participant acknowledges and agrees that the Company may refuse to issue or deliver the Shares. 

(b) Tax Withholding and Default Method of Tax Withholding. When Shares are issued as payment for vested Restricted Stock Units,
Participant generally will recognize immediate U.S. taxable income if Participant is a U.S. taxpayer. If Participant is a non-U.S. taxpayer, Participant will be subject to applicable taxes in his or her
jurisdiction. The minimum amount of Tax Obligations which the Company determines must be withheld with respect to this Award (“Tax Withholding Obligation”) will be satisfied by having the Company withhold otherwise deliverable Shares
having a fair market value equal to the minimum amount statutorily required to be withheld (or such greater amount as Participant may elect if permitted by the Committee, if such greater amount would not result in adverse financial accounting
consequences) (such method for satisfying the Tax Withholding Obligation, the “net settlement method”). By accepting this Award, Participant expressly consents to the net settlement method to cover the Tax Withholding Obligation and
agrees and acknowledges that Participant may not satisfy the Tax Withholding Obligation by any means other than such net settlement method, unless required to do so by the Committee or pursuant to the Committee’s express written consent.

 (c) Committee Discretion. If the Committee determines that Participant cannot satisfy Participant’s Tax Withholding Obligation
through the default procedure described in Section 8(b) or the Committee otherwise determines it is in the best interests of the Company for Participant to satisfy Participant’s Tax Withholding Obligation by a method other than through the
default procedure described in Section 8(b), it may permit or require Participant to satisfy Participant’s Tax Withholding Obligation, in whole or in part (without limitation), if permissible by applicable local law, by (i) paying
cash, (ii) electing to have Shares sold on Participant’s behalf at the prevailing market price pursuant to such procedures as the Company may specify from time to time, including through a broker-assisted arrangement (it being understood
that the Shares to be sold must have vested pursuant to the terms of this Award Agreement and the Plan); (iii) withholding the amount of such Tax Withholding Obligation from Participant’s wages or other cash compensation paid to Participant by
the Company and/or the Employer, (iv) delivering to the Company Shares that Participant owns and that have vested with a fair market value equal to the amount required to be withheld (or such greater amount as Participant may elect if permitted
by the Committee, if such greater amount would not result in adverse financial accounting consequences), or (v) such other means as the Committee deems appropriate. 

  
 5 

 (d) Company’s Obligation to Deliver Shares. For clarification purposes, in no
event will the Company issue Participant any Shares unless and until arrangements satisfactory to the Committee have been made for the payment of Participant’s Tax Withholding Obligation. If Participant fails to make satisfactory arrangements
for the payment of such Tax Withholding Obligations hereunder at the time any applicable Restricted Stock Units otherwise are scheduled to vest pursuant to Sections 4 or 6 or Participant’s Tax Withholding Obligations otherwise become due,
Participant will permanently forfeit such Restricted Stock Units to which Participant’s Tax Withholding Obligation relates and any right to receive Shares thereunder and such Restricted Stock Units will be returned to the Company at no cost to
the Company. Participant acknowledges and agrees that the Company may refuse to issue or deliver the Shares if such Tax Obligations are not delivered at the time they are due. 

11. Rights as Stockholder. Neither Participant nor any person claiming under or through Participant will have any of the rights or
privileges of a stockholder of the Company in respect of any Shares deliverable hereunder unless and until certificates representing such Shares (which may be in book entry form) will have been issued, recorded on the records of the Company or its
transfer agents or registrars, and delivered to Participant (including through electronic delivery to a brokerage account). After such issuance, recordation and delivery, Participant will have all the rights of a stockholder of the Company with
respect to voting such Shares and receipt of dividends and distributions on such Shares. 
 12. No Guarantee of Continued Service.
PARTICIPANT ACKNOWLEDGES AND AGREES THAT THE VESTING OF THE RESTRICTED STOCK UNITS PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE COMPANY (OR THE EMPLOYER) AND NOT THROUGH THE ACT OF
BEING HIRED, BEING GRANTED THIS RESTRICTED STOCK UNIT AWARD OR ACQUIRING SHARES HEREUNDER. PARTICIPANT FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT
CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL NOT INTERFERE IN ANY WAY WITH PARTICIPANT’S RIGHT OR THE RIGHT OF THE COMPANY (OR THE EMPLOYER)
TO TERMINATE PARTICIPANT’S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE. 
 13. Grant is Not
Transferable. Except to the limited extent provided in Section 9, this grant and the rights and privileges conferred hereby will not be transferred, assigned, pledged or hypothecated in any way (whether by operation of law or otherwise) and
will not be subject to sale under execution, attachment or similar process. Upon any attempt to transfer, assign, pledge, hypothecate or otherwise dispose of this grant, or any right or privilege conferred hereby, or upon any attempted sale under
any execution, attachment or similar process, this grant and the rights and privileges conferred hereby immediately will become null and void. 

14. Company’s Right of First Refusal. Subject to Section 13, before any Shares held by Participant or any
transferee (either being sometimes referred to herein as the “Holder”) may be sold or otherwise transferred (including transfer by gift or operation of law), the Company or its assignee(s) shall have a right of first refusal to purchase
the Shares on the terms and conditions set forth in this Section 14 (the “Right of First Refusal”). 

  
 6 

 (a) Notice of Proposed Transfer. The Holder of the Shares shall deliver to the
Company a written notice (the “Notice”) stating: (i) the Holder’s bona fide intention to sell or otherwise transfer such Shares; (ii) the name of each proposed purchaser or other transferee (“Proposed Transferee”);
(iii) the number of Shares to be transferred to each Proposed Transferee; and (iv) the bona fide cash price or other consideration for which the Holder proposes to transfer the Shares (the “Offered Price”), and the Holder shall
offer the Shares at the Offered Price to the Company or its assignee(s). 
 (b) Exercise of Right of First Refusal. At any time within
thirty (30) days after receipt of the Notice, the Company and/or its assignee(s) may, by giving written notice to the Holder, elect to purchase all, but not less than all, of the Shares proposed to be transferred to any one or more of the
Proposed Transferees, at the purchase price determined in accordance with subsection (c) below. 
 (c) Purchase Price. The
purchase price (“Right of First Refusal Price”) for the Shares purchased by the Company or its assignee(s) under this Section 14 shall be the Offered Price. If the Offered Price includes consideration other than cash, the cash
equivalent value of the non-cash consideration shall be determined by the Board in good faith. 
 (d)
Payment. Payment of the Right of First Refusal Price shall be made, at the option of the Company or its assignee(s), in cash (by check), by cancellation of all or a portion of any outstanding indebtedness of the Holder to the Company (or, in
the case of repurchase by an assignee, to the assignee), or by any combination thereof within thirty (30) days after receipt of the Notice or in the manner and at the times set forth in the Notice. 

(e) Holder’s Right to Transfer. If all of the Shares proposed in the Notice to be transferred to a given Proposed Transferee are
not purchased by the Company and/or its assignee(s) as provided in this Section 14, then the Holder may sell or otherwise transfer such Shares to that Proposed Transferee at the Offered Price or at a higher price, provided that such sale or
other transfer is consummated within one hundred and twenty (120) days after the date of the Notice, that any such sale or other transfer is effected in accordance with any applicable securities laws and that the Proposed Transferee agrees in
writing that the provisions of this Section 14 shall continue to apply to the Shares in the hands of such Proposed Transferee. If the Shares described in the Notice are not transferred to the Proposed Transferee within such period, a new Notice
shall be given to the Company, and the Company and/or its assignees shall again be offered the Right of First Refusal before any Shares held by the Holder may be sold or otherwise transferred. 

(f) Exception for Certain Family Transfers. Anything to the contrary contained in this Section 14 notwithstanding, the transfer of
any or all of the Shares during the Participant’s lifetime or on the Participant’s death by will or intestacy to the Participant’s immediate family or a trust for the benefit of the Participant’s immediate family shall be exempt
from the provisions of this Section 14. “Immediate Family” as used herein shall mean spouse, lineal descendant or antecedent, father, mother, brother or sister. In such case, the transferee or other recipient shall receive and hold
the Shares so transferred subject to the provisions of this Award Agreement, including this Section 14, and there shall be no further transfer of such Shares except in accordance with the terms of this Section 14. 

  
 7 

 (g) Termination of Right of First Refusal. The Right of First Refusal shall terminate
as to any Shares upon the earlier of (i) the first sale of Common Stock of the Company to the general public, or (ii) a Change in Control in which the successor corporation has equity securities that are publicly traded. 

15. Restrictive Legends and Stop-Transfer Orders. 

(a) Legends. Participant understands and agrees that the Company shall cause the legends set forth below, or legends substantially
equivalent thereto, to be placed upon any certificate(s) evidencing ownership of the Shares together with any other legends that may be required by the Company or by state or federal securities laws: 

THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE “ACT”) AND MAY NOT BE OFFERED, SOLD
OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT OR, IN THE OPINION OF COUNSEL SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION IS IN COMPLIANCE
THEREWITH. 
 THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER AND A RIGHT OF FIRST REFUSAL IN
FAVOR OF THE ISSUER OR ITS ASSIGNEE(S) AS SET FORTH IN THE RESTRICTED STOCK UNIT AWARD AGREEMENT BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THESE SHARES, A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE ISSUER. SUCH TRANSFER
RESTRICTIONS AND RIGHT OF FIRST REFUSAL IN FAVOR OF THE ISSUER OR ITS ASSIGNEE(S) ARE BINDING ON TRANSFEREES OF THESE SHARES. 
 THE SHARES
REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON TRANSFER FOR A PERIOD OF TIME FOLLOWING THE EFFECTIVE DATE OF THE UNDERWRITTEN PUBLIC OFFERING OF THE COMPANY’S SECURITIES SET FORTH IN AN AGREEMENT BETWEEN THE ISSUER AND THE
ORIGINAL HOLDER OF THESE SHARES AND MAY NOT BE SOLD OR OTHERWISE DISPOSED OF BY THE HOLDER PRIOR TO THE EXPIRATION OF SUCH PERIOD WITHOUT THE CONSENT OF THE COMPANY OR THE MANAGING UNDERWRITER. 

(b) Stop-Transfer Notices. Participant agrees that, in order to ensure compliance with the restrictions referred to herein, the Company
may issue appropriate “stop transfer” instructions to its transfer agent, if any, and that, if the Company transfers its own securities, it may make appropriate notations to the same effect in its own records. 

  
 8 

 (c) Refusal to Transfer. The Company shall not be required (i) to transfer on
its books any Shares that have been sold or otherwise transferred in violation of any of the provisions of this Award Agreement or (ii) to treat as owner of such Shares or to accord the right to vote or pay dividends to any purchaser or other
transferee to whom such Shares shall have been so transferred. 
 16. Restrictions on Sale of Securities. Any sale of the Shares
issued under this Award Agreement will be subject to any market blackout-period that may be imposed by the Company and must comply with the Company’s insider trading policies and other Applicable Laws. 

17. Nature of Grant. In accepting the grant, Participant acknowledges, understands and agrees that: 

(a) the grant of the Restricted Stock Units is voluntary and occasional and does not create any contractual or other right to receive future
grants of Restricted Stock Units, or benefits in lieu of Restricted Stock Units, even if Restricted Stock Units have been granted in the past; 

(b) all decisions with respect to future Restricted Stock Units or other grants, if any, will be at the sole discretion of the Company; 

(c) Participant is voluntarily participating in the Plan; 

(d) the Restricted Stock Units and the Shares subject to the Restricted Stock Units are not intended to replace any pension rights or
compensation; 
 (e) the Restricted Stock Units and the Shares subject to the Restricted Stock Units, and the income and value of same, are
not part of normal or expected compensation for purposes of calculating any severance, resignation, termination, redundancy, dismissal, end-of-service payments, bonuses,
long-service awards, pension or retirement or welfare benefits or similar payments; 
 (f) the future value of the underlying Shares is
unknown, indeterminable and cannot be predicted; 
 (g) for purposes of the Restricted Stock Units, Participant’s status as a Service
Provider will be considered terminated as of the date Participant is no longer actively providing services to the Company or any Parent or Subsidiary (regardless of the reason for such termination and whether or not later to be found invalid or in
breach of employment laws in the jurisdiction where Participant is a Service Provider or the terms of Participant’s employment or service agreement, if any), and unless otherwise expressly provided in this Award Agreement (including by
reference in the Notice of Grant to other arrangements or contracts) or determined by the Committee, Participant’s right to vest in the Restricted Stock Units under the Plan, if any, will terminate as of such date and will not be extended by
any notice period (e.g., Participant’s period of service would not include any contractual notice period or any period of “garden leave” or similar period mandated under employment laws in the jurisdiction where Participant is a
Service Provider or the terms of Participant’s employment or service agreement, if any, unless Participant is providing bona fide services during such time); the Committee shall have the exclusive discretion to determine when Participant is no
longer actively providing services for purposes of the Restricted Stock Units grant (including whether Participant may still be considered to be providing services while on a leave of absence); 

  
 9 

 (h) unless otherwise provided in the Plan or by the Company in its discretion, the
Restricted Stock Units and the benefits evidenced by this Award Agreement do not create any entitlement to have the Restricted Stock Units or any such benefits transferred to, or assumed by, another company or exchanged, cashed out or substituted
for, in connection with any corporate transaction affecting the Shares; and 
 (i) the following provisions apply only if Participant is
providing services outside the United States: 
 (i) the Restricted Stock Units and the Shares subject to the Restricted Stock Units are not
part of normal or expected compensation or salary for any purpose; 
 (ii) Participant acknowledges and agrees that none of the Company, the
Employer or any Parent or Subsidiary shall be liable for any foreign exchange rate fluctuation between Participant’s local currency and the United States Dollar that may affect the value of the Restricted Stock Units or of any amounts
due to Participant pursuant to the settlement of the Restricted Stock Units or the subsequent sale of any Shares acquired upon settlement; and 

(iii) no claim or entitlement to compensation or damages shall arise from forfeiture of the Restricted Stock Units resulting from the
termination of Participant’s status as a Service Provider (for any reason whatsoever whether or not later found to be invalid or in breach of employment laws in the jurisdiction where Participant is a Service Provider or the terms of
Participant’s employment or service agreement, if any), and in consideration of the grant of the Restricted Stock Units to which Participant is otherwise not entitled, Participant irrevocably agrees never to institute any claim against the
Company, any Parent or Subsidiary or the Employer, waives his or her ability, if any, to bring any such claim, and releases the Company, any Parent or Subsidiary and the Employer from any such claim; if, notwithstanding the foregoing, any such claim
is allowed by a court of competent jurisdiction, then, by participating in the Plan, Participant shall be deemed irrevocably to have agreed not to pursue such claim and agrees to execute any and all documents necessary to request dismissal or
withdrawal of such claim. 
 18. No Advice Regarding Grant. The Company is not providing any tax, legal or financial advice, nor is
the Company making any recommendations regarding Participant’s participation in the Plan, or Participant’s acquisition or sale of the underlying Shares. Participant is hereby advised to consult with his or her own personal tax, legal and
financial advisors regarding his or her participation in the Plan before taking any action related to the Plan. 
 19.
Data Privacy. Participant hereby explicitly and unambiguously consents to the collection, use and transfer, in electronic or other form, of Participant’s personal data as described in this Award Agreement and any
other Restricted Stock Unit grant materials by and among, as applicable, the Employer, the Company and any Parent or Subsidiary for the exclusive purpose of implementing, administering and managing Participant’s participation in the
Plan. 

  
 10 

 Participant understands that the Company and the Employer may hold certain personal information about
Participant, including, but not limited to, Participant’s name, home address and telephone number, date of birth, social insurance number or other identification number, salary, nationality, job title, any Shares or directorships held in the
Company, details of all Restricted Stock Units or any other entitlement to Shares awarded, canceled, exercised, vested, unvested or outstanding in Participant’s favor (“Data”), for the exclusive purpose of implementing, administering
and managing the Plan. 
 Participant understands that Data will be transferred to a stock plan service provider as may be selected by the
Company in the future, which is assisting the Company with the implementation, administration and management of the Plan. Participant understands that the recipients of the Data may be located in the United States or elsewhere, and that the
recipients’ country of operation (e.g., the United States) may have different data privacy laws and protections than Participant’s country. Participant understands that if he or she resides outside the United States, he or she may request
a list with the names and addresses of any potential recipients of the Data by contacting his or her local human resources representative. Participant authorizes the Company, any stock plan service provider selected by the Company and any other
possible recipients which may assist the Company (presently or in the future) with implementing, administering and managing the Plan to receive, possess, use, retain and transfer the Data, in electronic or other form, for the sole purpose of
implementing, administering and managing his or her participation in the Plan. Participant understands that Data will be held only as long as is necessary to implement, administer and manage Participant’s participation in the Plan. Participant
understands if he or she resides outside the United States, he or she may, at any time, view Data, request additional information about the storage and processing of Data, require any necessary amendments to Data or refuse or withdraw the consents
herein, in any case without cost, by contacting in writing his or her local human resources representative. Further, Participant understands that he or she is providing the consents herein on a purely voluntary basis. If Participant does not
consent, or if Participant later seeks to revoke his or her consent, his or her status as a Service Provider and career with the Employer will not be adversely affected; the only adverse consequence of refusing or withdrawing Participant’s
consent is that the Company would not be able to grant Participant Restricted Stock Units or other equity awards or administer or maintain such awards. Therefore, Participant understands that refusing or withdrawing his or her consent may affect
Participant’s ability to participate in the Plan. For more information on the consequences of Participant’s refusal to consent or withdrawal of consent, Participant understands that he or she may contact his or her local human resources
representative. 
 20. Address for Notices. Any notice to be given to the Company under the terms of this Award Agreement will
be addressed to the Company at Thorne HealthTech, Inc. 152 W. 57th Street, New York, New York 10019, or at such other address as the Company may hereafter designate in writing. 

21. Electronic Delivery. The Company may, in its sole discretion, decide to deliver any documents related to the Restricted Stock Units
awarded under the Plan or future Restricted Stock Units that may be awarded under the Plan by electronic means or request Participant’s consent to participate in the Plan by electronic means. Participant hereby consents to receive such
documents by electronic delivery and agrees to participate in the Plan through any on-line or electronic system established and maintained by the Company or another third party designated by the Company. 

  
 11 

 22. No Waiver. Either party’s failure to enforce any provision or provisions of
this Award Agreement shall not in any way be construed as a waiver of any such provision or provisions, nor prevent that party from thereafter enforcing each and every other provision of this Award Agreement. The rights granted both parties herein
are cumulative and shall not constitute a waiver of either party’s right to assert all other legal remedies available to it under the circumstances. 

23. Successors and Assigns. The Company may assign any of its rights under this Award Agreement to single or multiple assignees, and
this Award Agreement shall inure to the benefit of the successors and assigns of the Company. Subject to the restrictions on transfer herein set forth, this Award Agreement shall be binding upon Participant and his or her heirs, executors,
administrators, successors and assigns. The rights and obligations of Participant under this Award Agreement may only be assigned with the prior written consent of the Company. 

24. Additional Conditions to Issuance of Stock. If at any time the Company will determine, in its discretion, that the listing,
registration, qualification or rule compliance of the Shares upon any securities exchange or under any state, federal or foreign law, the tax code and related regulations or under the rulings or regulations of the United States Securities and
Exchange Commission or any other governmental regulatory body or the clearance, consent or approval of the United States Securities and Exchange Commission or any other governmental regulatory authority is necessary or desirable as a condition to
the issuance of Shares to Participant (or his or her estate) hereunder, such issuance will not occur unless and until such listing, registration, qualification, rule compliance, clearance, consent or approval will have been completed, effected or
obtained free of any conditions not acceptable to the Company. Subject to the terms of the Award Agreement and the Plan, the Company shall not be required to issue any certificate or certificates for Shares hereunder prior to the lapse of such
reasonable period of time following the date of vesting of the Restricted Stock Units as the Committee may establish from time to time for reasons of administrative convenience. 

25. Language. If Participant has received this Award Agreement or any other document related to the Plan translated into a language
other than English and if the meaning of the translated version is different than the English version, the English version will control. 

26. Interpretation. The Committee will have the power to interpret the Plan and this Award Agreement and to adopt such rules for the
administration, interpretation and application of the Plan as are consistent therewith and to interpret or revoke any such rules (including, but not limited to, the determination of whether or not any Restricted Stock Units have vested). All actions
taken and all interpretations and determinations made by the Committee in good faith will be final and binding upon Participant, the Company and all other interested persons. Neither the Committee nor any person acting on behalf of the Committee
will be personally liable for any action, determination or interpretation made in good faith with respect to the Plan or this Award Agreement. 

  
 12 

 27. Modifications to the Award Agreement. This Award Agreement constitutes the entire
understanding of the parties on the subjects covered. Participant expressly warrants that he or she is not accepting this Award Agreement in reliance on any promises, representations, or inducements other than those contained herein. Modifications
to this Award Agreement or the Plan can be made only in an express written contract executed by a duly authorized officer of the Company. Notwithstanding anything to the contrary in the Plan or this Award Agreement, the Company reserves the right to
revise this Award Agreement as it deems necessary or advisable, in its sole discretion and without the consent of Participant, to comply with Section 409A or to otherwise avoid imposition of any additional tax or income recognition under
Section 409A in connection to this Award of Restricted Stock Units. 
 28. Governing Law; Severability. This Award Agreement and
the Restricted Stock Units are governed by the internal substantive laws, but not the choice of law rules, of New York. In the event that any provision hereof becomes or is declared by a court of competent jurisdiction to be illegal, unenforceable
or void, this Award Agreement shall continue in full force and effect. 
 29. Entire Agreement. The Plan is incorporated herein by
reference. The Plan and this Award Agreement (including the exhibits and addendums referenced herein) constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior undertakings and
agreements of the Company and Participant with respect to the subject matter hereof, and may not be modified adversely to the Participant’s interest except by means of a writing signed by the Company and Participant. 

30. Country Addendum. Notwithstanding any provisions in this Award Agreement, the Restricted Stock Unit grant shall be subject to any
special terms and conditions set forth in any appendix to this Award Agreement for any country whose laws are applicable to Participant and this Award of Restricted Stock Units (as determined by the Committee in its sole discretion) (the
“Country Addendum”). Moreover, if Participant relocates to one of the countries included in the Country Addendum, the special terms and conditions for such country will apply to Participant, to the extent the Company determines that the
application of such terms and conditions is necessary or advisable for legal or administrative reasons. The Country Addendum constitutes part of this Award Agreement. Participant acknowledges receipt of a copy of the Plan and represents that he or
she is familiar with the terms and provisions thereof, and hereby accepts this Award Agreement subject to all of the terms and provisions thereof. Participant has reviewed the Plan and this Award Agreement in their entirety, has had an opportunity
to obtain the advice of counsel prior to executing this Award Agreement and fully understands all provisions of this Award Agreement. Participant hereby agrees to accept as binding, conclusive and final all decisions or interpretations of the
Committee upon any questions arising under the Plan or this Award Agreement. Participant further agrees to notify the Company upon any change in the residence address indicated below.

 THORNE HEALTHTECH, INC. 

RESTRICTED STOCK UNIT AWARD AGREEMENT 

COUNTRY ADDENDUM 
 TERMS AND
CONDITIONS 
 This Country Addendum includes additional terms and conditions that govern the award of Restricted Stock Units under the Plan if
Participant works in one of the countries listed below. If Participant is a citizen or resident of a country (or is considered as such for local law purposes) other than the one in which he or she is currently working or if Participant relocates to
another country after receiving the Award of Restricted Stock Units, the Company will, in its discretion, determine the extent to which the terms and conditions contained herein will be applicable to Participant. 

Certain capitalized terms used but not defined in this Country Addendum shall have the meanings set forth in the Plan and/or the Award Agreement to which this
Country Addendum is attached. 
 NOTIFICATIONS 

This Country Addendum also includes notifications relating to exchange control and other issues of which Participant should be aware with respect to his or her
participation in the Plan. The information is based on the exchange control, securities and other laws in effect in the countries listed in this Country Addendum, as of [_______]. Such laws are often complex and change frequently. As a result, the
Company strongly recommends that Participant not rely on the notifications herein as the only source of information relating to the consequences of his or her participation in the Plan because the information may be outdated when Participant vests
in the Restricted Stock Units and acquires Shares, or when Participant subsequently sell Shares acquired under the Plan. 
 In addition, the notifications
are general in nature and may not apply to Participant’s particular situation, and the Company is not in a position to assure Participant of any particular result. Accordingly, Participant is advised to seek appropriate professional advice as
to how the relevant laws in Participant’s country may apply to Participant’s situation. 
 Finally, if Participant is a citizen or resident of a
country other than the one in which Participant is currently working (or is considered as such for local law purposes) or if Participant moves to another country after receiving an Award of Restricted Stock Units, the information contained herein
may not be applicable to Participant.

 In connection with the receipt of the above-listed Securities, the undersigned Participant represents to the Company the
following: 
 (a) Participant is aware of the Company’s business affairs and financial condition and has acquired sufficient information
about the Company to reach an informed and knowledgeable decision to acquire the Securities. Participant is acquiring these Securities for investment for Participant’s own account only and not with a view to, or for resale in connection with,
any “distribution” thereof within the meaning of the Securities Act of 1933, as amended (the “Securities Act”). 
 (b)
Participant acknowledges and understands that the Securities constitute “restricted securities” under the Securities Act and have not been registered under the Securities Act in reliance upon a specific exemption therefrom, which exemption
depends upon, among other things, the bona fide nature of Participant’s investment intent as expressed herein. In this connection, Participant understands that, in the view of the Securities and Exchange Commission, the statutory basis for such
exemption may be unavailable if Participant’s representation was predicated solely upon a present intention to hold these Securities for the minimum capital gains period specified under tax statutes, for a deferred sale, for or until an
increase or decrease in the market price of the Securities, or for a period of one (1) year or any other fixed period in the future. Participant further understands that the Securities must be held indefinitely unless they are subsequently
registered under the Securities Act or an exemption from such registration is available. Participant further acknowledges and understands that the Company is under no obligation to register the Securities. Participant understands that the
certificate evidencing the Securities shall be imprinted with any legend required under applicable state securities laws. 
 (c) Participant
is familiar with the provisions of Rule 701 and Rule 144, each promulgated under the Securities Act, which, in substance, permit limited public resale of “restricted securities” acquired, directly or indirectly from the issuer
thereof, in a non-public offering subject to the satisfaction of certain conditions. Rule 701 provides that if the issuer qualifies under Rule 701 at the time of the grant of the Restricted Stock
Unit Award to Participant, the receipt of the Securities shall be exempt from registration under the Securities Act. In the event the Company becomes subject to the reporting requirements of Section 13 or 15(d) of the Securities Exchange Act of
1934, ninety (90) days thereafter (or such longer period as any market stand-off agreement may require) the Securities 

 
exempt under Rule 701 may be resold, subject to the satisfaction of the applicable conditions specified by Rule 144, including in the case of affiliates (1) the availability of
certain public information about the Company, (2) the amount of Securities being sold during any three (3) month period not exceeding specified limitations, (3) the resale being made in an unsolicited “broker’s
transaction”, transactions directly with a “market maker” or “riskless principal transactions” (as those terms are defined under the Securities Exchange Act of 1934) and (4) the timely filing of a Form 144, if
applicable. 
 In the event that the Company does not qualify under Rule 701 at the time of grant of the Restricted Stock Unit Award,
then the Securities may be resold in certain limited circumstances subject to the provisions of Rule 144, which may require (1) the availability of current public information about the Company; (2) the resale to occur more than a
specified period after the purchase and full payment (within the meaning of Rule 144) for the Securities; and (3) in the case of the sale of Securities by an affiliate, the satisfaction of the conditions set forth in sections (2), (3)
and (4) of the paragraph immediately above. 
 (d) Participant further understands that in the event all of the applicable requirements
of Rule 701 or 144 are not satisfied, registration under the Securities Act, compliance with Regulation A, or some other registration exemption shall be required; and that, notwithstanding the fact that Rules 144 and 701 are not exclusive,
the Staff of the Securities and Exchange Commission has expressed its opinion that persons proposing to sell private placement securities other than in a registered offering and otherwise than pursuant to Rules 144 or 701 shall have a
substantial burden of proof in establishing that an exemption from registration is available for such offers or sales, and that such persons and their respective brokers who participate in such transactions do so at their own risk. Participant
understands that no assurances can be given that any such other registration exemption shall be available in such event.
