of any Award, which terms and conditions may differ among individual Awards and grantees, and to approve the forms of Award Certificates;

 

(v)           to
determine the vesting, exercisability and payment of Awards, including the authority to accelerate the vesting and exercisability of all
or any portion of any Award;

 

(vi)          subject
to the provisions of Section 5(c), to extend at any time the period in which Stock Options may be exercised; and

as it shall deem advisable; to interpret the terms and provisions of the Plan and any Award (including related written instruments); to

and to otherwise supervise the administration of the Plan.

 

All decisions and interpretations of the Administrator

of one or more officers of the Company, including the Chief Executive Officer of the Company, all or part of the Administrator’s
authority and duties with respect to the granting of Awards to individuals who are (i) not subject to the reporting and other provisions
of Section 16 of the Exchange Act and (ii) not members of the delegated committee. Any such delegation by the Administrator
shall include a limitation as to the amount of Stock underlying Awards that may be granted during the period of the delegation and shall
contain guidelines as to the determination of the exercise price and the vesting criteria. The Administrator may revoke or amend the terms
of a delegation at any time but such action shall not invalidate any prior actions of the Administrator’s delegate or delegates
that were consistent with the terms of the Plan.

 

    4

     

    

 

(d)           Award
Certificate. Awards under the Plan shall be evidenced by Award Certificates that set forth the terms, conditions and limitations for
each Award which may include, without limitation, the term of an Award and the provisions applicable in the event employment or service

(e)           Indemnification.
Neither the Board nor the Administrator, nor any member of either or any delegate thereof, shall be liable for any act, omission, interpretation,

by the Plan; (ii) determine which individuals outside the United States are eligible to participate in the Plan; (iii) modify
the terms and conditions of any Award granted to individuals outside the United States to comply with applicable foreign laws; (iv) establish
subplans and modify exercise procedures and other terms and procedures, to the extent the Administrator determines such actions to be
necessary or advisable (and such subplans and/or modifications shall be attached to this Plan as appendices); provided, however, that
no such subplans and/or modifications shall increase the share limitations contained in Section 3(a) hereof; and (v) take
any action, before or after an Award is made, that the Administrator determines to be necessary or advisable to obtain approval or comply,
or facilitate compliance, with any local governmental regulatory exemptions or approvals. Notwithstanding the foregoing, the Administrator

States securities law, the Code, or any other applicable United States governing statute or law.

SECTION 3. STOCK
ISSUABLE UNDER THE PLAN; MERGERS; SUBSTITUTION

 

(a)            Stock
Issuable.

 

(i)            Share
Reserve. The maximum number of shares of Stock reserved and available for issuance under the Plan (the “Share
Reserve”) shall be 42,500,000 shares (the “Initial Limit”), subject to adjustment as provided in this
Section 3, plus on January 1, 2022 and each January 1 thereafter, the number of shares of Stock reserved and
available for issuance under the Plan shall be cumulatively increased by (i) five percent of the number of shares of Stock
issued and outstanding on the immediately preceding December 31 or (ii) such lesser number of shares as determined by the
Administrator (the “Annual Increase”). Subject to such overall limitation, the maximum aggregate number of shares
of Stock that may be issued in the form of Incentive Stock Options shall not exceed the Initial Limit, as cumulatively increased on
January 1, 2022 and each January 1 thereafter by the lesser of the Annual Increase for such year or 42,5000,000 
shares of Stock, subject in all cases to adjustment as provided in Section 3(b). For purposes of this limitation, the shares of
Stock underlying any awards under the Plan that are forfeited, canceled, held back upon exercise of an option or settlement of an
award to cover the exercise price or tax withholding, reacquired by the Company prior to vesting, satisfied without the issuance of
Stock or otherwise terminated (other than by exercise) shall be added back to the Share Reserve and, to the extent permitted under
Section 422 of the Code and the regulations promulgated thereunder, the shares of Stock that may be issued as Incentive Stock
Options. In the event the Company repurchases shares of Stock on the open market, such shares shall not be added to the shares of
Stock available for issuance under the Plan. Subject to such overall limitations, shares of Stock may be issued up to such maximum
number pursuant to any type or types of Award. The shares available for issuance under the Plan may be authorized but unissued
shares of Stock or shares of Stock reacquired by the Company.

 

(ii)           Earnout
RSU Share Reserve. An additional 1,400,000  shares of Stock, subject to adjustment as provided in this Section 3, shall
be reserved under the Plan to be used solely and exclusive for the grant of Earnout RSUs (as defined in the Merger Agreement)
pursuant to the terms and conditions of the Merger Agreement and may be used solely for such purpose (the “Earnout RSU
Share Reserve”). The shares of Stock issuable under any Earnout RSUs that may be awarded under this
Section 3(a)(ii) shall be in addition to and shall not reduce the Share Reserve, provided that Earnout RSUs shall
constitute Awards under this Plan for all other relevant purposes. The shares of Stock underlying any Earnout RSUs that are
forfeited, canceled, held back upon settlement of an Earnout RSU to cover any applicable tax withholding, reacquired or repurchased
by the Company, satisfied without the issuance of Stock or otherwise terminated (other than by settlement of the Earnout RSU) shall
be added back to the shares available for grant under this Section 3(a)(ii), and shall not be added to the Share Reserve.

 

    6

     

    

 

(b)           Changes
in Stock. Subject to Section 3(c) hereof, if, as a result of any reorganization, recapitalization, reclassification, stock
dividend, extraordinary cash dividend, stock split, reverse stock split or other similar change in the Company’s capital stock,
the outstanding shares of Stock are increased or decreased or are exchanged for a different number or kind of shares or other securities
of the Company, or additional shares or new or different shares or other securities of the Company or other non-cash assets are distributed
with respect to such shares of Stock or other securities, or, if, as a result of any merger or consolidation, sale of all or substantially
all of the assets of the Company, the outstanding shares of Stock are converted into or exchanged for securities of the Company or any
successor entity (or a parent or subsidiary thereof), the Administrator shall make an appropriate or proportionate adjustment in (i) the
maximum number of shares reserved for issuance under the Plan (i.e., the Share Reserve and the Earnout RSU Share Reserve), including the
maximum number of shares that may be issued in the form of Incentive Stock Options, (ii) the number and kind of shares or other securities
subject to any then outstanding Awards under the Plan, (iii) the repurchase price, if any, per share subject to each outstanding
Restricted Stock Award, and (iv) the exercise price for each share subject to any then outstanding Stock Options and Stock Appreciation
Rights under the Plan, without changing the aggregate exercise price (i.e., the exercise price multiplied by the number of shares subject
to Stock Options and Stock Appreciation Rights) as to which such Stock Options and Stock Appreciation Rights remain exercisable. The Administrator
shall also make equitable or proportionate adjustments in the number of shares subject to outstanding Awards and the exercise price and
the terms of outstanding Awards to take into consideration cash dividends paid other than in the ordinary course or any other extraordinary
corporate event. The adjustment by the Administrator shall be final, binding and conclusive. No fractional shares of Stock shall be issued
under the Plan resulting from any such adjustment, but the Administrator in its discretion may make a cash payment in lieu of fractional
shares.

 

(c)            Mergers
and Other Transactions. In the case of and subject to the consummation of a Sale Event, the parties thereto may cause the assumption
or continuation of Awards theretofore granted by the successor entity, or the substitution of such Awards with new Awards of the successor
entity or parent thereof, with appropriate adjustment as to the number and kind of shares and, if appropriate, the per share exercise
prices, as such parties shall agree. To the extent the parties to such Sale Event do not provide for the assumption, continuation or substitution
of Awards, upon the effective time of the Sale Event, the Plan and all outstanding Awards granted hereunder shall terminate. In such case,
except as may be otherwise provided in the relevant Award Certificate, all Awards with time-based vesting, conditions or restrictions
shall become fully vested and exercisable or nonforfeitable as of the effective time of the Sale Event, and all Awards with conditions
and restrictions relating to the attainment of performance goals may become vested and nonforfeitable in connection with a Sale Event
in the Administrator’s discretion or to the extent specified in the relevant Award Certificate. In the event of such termination,
(i) the Company shall have the option (in its sole discretion) to make or provide for a payment, in cash or in kind, to the grantees
holding Options and Stock Appreciation Rights, in exchange for the cancellation thereof, in an amount equal to the difference between
(A) the Sale Price multiplied by the number of shares of Stock subject to outstanding Options and Stock Appreciation Rights (to the
extent then exercisable at prices not in excess of the Sale Price) and (B) the aggregate exercise price of all such outstanding Options
and Stock Appreciation Rights (provided that, in the case of an Option or Stock Appreciation Right with an exercise price equal to or
greater than the Sale Price, such Option or Stock Appreciation Right shall be cancelled for no consideration); or (ii) each grantee
shall be permitted, within a specified period of time prior to the consummation of the Sale Event as determined by the Administrator,
to exercise all outstanding Options and Stock Appreciation Rights (to the extent then exercisable) held by such grantee. The Company shall
also have the option (in its sole discretion) to make or provide for a payment, in cash or in kind, to the grantees holding other Awards
in an amount equal to the Sale Price multiplied by the number of vested shares of Stock under such Awards.

 

    7

     

    

 

(d)           Maximum
Awards to Non-Employee Directors. Notwithstanding anything to the contrary in this Plan, the value of all Awards awarded under this
Plan and all other cash compensation paid by the Company to any Non-Employee Director in any calendar year for service as a Non-Employee
Director shall not exceed $750,000; provided, however, that such amount shall be $1,500,000 for the calendar year in which the applicable
Non-Employee Director is initially elected or appointed to the Board. For the purpose of this limitation, the value of any Award shall
be its grant date fair value, as determined in accordance with FASB ASC 718 or successor provision but excluding the impact of estimated
forfeitures related to service-based vesting provisions.

 

SECTION 4. ELIGIBILITY

 

Grantees under the Plan will be such current or
future employees, Non-Employee Directors and Consultants of the Company and its Affiliates as are selected from time to time by the Administrator
in its sole discretion; provided that Awards may not be granted to employees, Directors or Consultants who are or would be providing services
only to any “parent” of the Company, as such term is defined in Rule 405 of the Act, unless (i) the stock underlying
the Awards is treated as “service recipient stock” under Section 409A or (ii) the Company, in consultation with
its legal counsel, has determined that such Awards are exempt from or otherwise comply with Section 409A.

 

SECTION 5. STOCK
OPTIONS

 

(a)            Award
of Stock Options. The Administrator may grant Stock Options under the Plan. Any Stock Option granted under the Plan shall be in such
form as the Administrator may from time to time approve.

 

Stock Options granted under the Plan may be either
Incentive Stock Options or Non-Qualified Stock Options. Incentive Stock Options may be granted only to employees of the Company or any
Subsidiary that is a “subsidiary corporation” within the meaning of Section 424(f) of the Code. To the extent that
any Option does not qualify as an Incentive Stock Option, it shall be deemed a Non-Qualified Stock Option.

 

Stock Options granted pursuant to this Section 5
shall be subject to the following terms and conditions and shall contain such additional terms and conditions, not inconsistent with the
terms of the Plan, as the Administrator shall deem desirable. If the Administrator so determines, Stock Options may be granted in lieu
of cash compensation at the optionee’s election, subject to such terms and conditions as the Administrator may establish.

 

(b)           Exercise
Price. The exercise price per share for the Stock covered by a Stock Option granted pursuant to this Section 5 shall be determined
by the Administrator at the time of grant but shall not be less than 100 percent of the Fair Market Value on the date of grant. In the
case of an Incentive Stock Option that is granted to a Ten Percent Owner, the exercise price of such Incentive Stock Option shall be not
less than 110 percent of the Fair Market Value on the grant date. Notwithstanding the foregoing, Stock Options may be granted with an
exercise price per share that is less than 100 percent of the Fair Market Value on the date of grant (i) pursuant to a transaction
described in, and in a manner consistent with, Section 424(a) of the Code, (ii) to individuals who are not subject to U.S.
income tax on the date of grant or (iii) the Stock Option is otherwise compliant with Section 409A.

 

    8

     

    

 

(c)            Option
Term. The term of each Stock Option shall be fixed by the Administrator, but no Stock Option shall be exercisable more than ten years
after the date the Stock Option is granted. In the case of an Incentive Stock Option that is granted to a Ten Percent Owner, the term
of such Stock Option shall be no more than five years from the date of grant.

 

(d)           Exercisability;
Rights of a Stockholder. Stock Options shall become exercisable at such time or times, whether or not in installments, as shall be
determined by the Administrator at or after the grant date. The Administrator may at any time accelerate the exercisability of all or
any portion of any Stock Option. An optionee shall have the rights of a stockholder only as to shares acquired upon the exercise of a
Stock Option and not as to unexercised Stock Options.

 

(e)            Method
of Exercise. Stock Options may be exercised in whole or in part, by giving written or electronic notice of exercise to the Company,
specifying the number of shares to be purchased. Payment of the purchase price may be made by one or more of the following methods except
to the extent otherwise provided in the Award Certificate:

 

(i)            In
cash, by certified or bank check or other instrument acceptable to the Administrator;

 

(ii)           Through
the delivery (or attestation to the ownership following such procedures as the Company may prescribe) of shares of Stock that are not
then subject to restrictions under any Company plan. Such surrendered shares shall be valued at Fair Market Value on the exercise date;

 

(iii)          By
the optionee delivering to the Company a properly executed exercise notice together with irrevocable instructions to a broker to promptly
deliver to the Company cash or a check payable and acceptable to the Company for the purchase price; provided that in the event the optionee
chooses to pay the purchase price as so provided, the optionee and the broker shall comply with such procedures and enter into such agreements
of indemnity and other agreements as the Company shall prescribe as a condition of such payment procedure; or

 

(iv)          With
respect to Stock Options that are not Incentive Stock Options, by a “net exercise” arrangement pursuant to which the Company
will reduce the number of shares of Stock issuable upon exercise by the largest whole number of shares with a Fair Market Value that does
not exceed the aggregate exercise price; or

 

(v)           Through
any other method as may be determined by the Administrator from time to time.

 

    9

     

    

 

Payment instruments will be received subject to collection. The transfer
to the optionee on the records of the Company or of the transfer agent of the shares of Stock to be purchased pursuant to the exercise
of a Stock Option will be contingent upon receipt from the optionee (or a purchaser acting in his stead in accordance with the provisions
of the Stock Option) by the Company of the full purchase price for such shares and the fulfillment of any other requirements contained
in the Award Certificate or applicable provisions of laws (including the satisfaction of any withholding taxes that the Company is obligated
to withhold with respect to the optionee). In the event an optionee chooses to pay the purchase price by previously-owned shares of Stock
through the attestation method, the number of shares of Stock transferred to the optionee upon the exercise of the Stock Option shall
be net of the number of attested shares. In the event that the Company establishes, for itself or using the services of a third party,
an automated system for the exercise of Stock Options, such as a system using an internet website or interactive voice response, then
the paperless exercise of Stock Options may be permitted through the use of such an automated system.

 

(f)            Annual
Limit on Incentive Stock Options. To the extent required for “incentive stock option” treatment under Section 422
of the Code, the aggregate Fair Market Value (determined as of the time of grant) of the shares of Stock with respect to which Incentive
Stock Options granted under this Plan and any other plan of the Company or its parent and subsidiary corporations become exercisable for
the first time by an optionee during any calendar year shall not exceed $100,000. To the extent that any Stock Option exceeds this limit,
it shall constitute a Non-Qualified Stock Option.

 

SECTION 6. STOCK
APPRECIATION RIGHTS

 

(a)           Award
of Stock Appreciation Rights. The Administrator may grant Stock Appreciation Rights under the Plan. A Stock Appreciation Right is
an Award entitling the recipient to receive shares of Stock (or cash, to the extent explicitly provided for in the applicable Award Certificate)
having a value equal to the excess of the Fair Market Value of a share of Stock on the date of exercise over the exercise price of the
Stock Appreciation Right multiplied by the number of shares of Stock with respect to which the Stock Appreciation Right shall have been
exercised.

 

(b)          Exercise
Price of Stock Appreciation Rights. The exercise price of a Stock Appreciation Right shall not be less than 100 percent of the Fair
Market Value of the Stock on the date of grant.

 

(c)           Grant
and Exercise of Stock Appreciation Rights. Stock Appreciation Rights may be granted by the Administrator independently of any Stock
Option granted pursuant to Section 5 of the Plan.

 

(d)           Terms
and Conditions of Stock Appreciation Rights. Stock Appreciation Rights shall be subject to such terms and conditions as shall be determined
on the date of grant by the Administrator. The term of a Stock Appreciation Right may not exceed ten years. The terms and conditions of
each such Award shall be determined by the Administrator, and such terms and conditions may differ among individual Awards and grantees.

 

SECTION 7. RESTRICTED
STOCK AWARDS

 

(a)           Nature
of Restricted Stock Awards. The Administrator may grant Restricted Stock Awards under the Plan. A Restricted Stock Award is any Award
of Restricted Shares subject to such restrictions and conditions as the Administrator may determine at the time of grant. Conditions may
be based on continuing employment (or other Service Relationship) and/or achievement of pre-established performance goals and objectives.

 

    10

     

    

 

(b)           Rights
as a Stockholder. Upon the grant of the Restricted Stock Award and payment of any applicable purchase price, a grantee shall have
the rights of a stockholder with respect to the voting of the Restricted Shares and receipt of dividends; provided that if the lapse of
restrictions with respect to the Restricted Stock Award is tied to the attainment of performance goals, any dividends paid by the Company
during the performance period shall accrue and shall not be paid to the grantee until and to the extent the performance goals are met
with respect to the Restricted Stock Award. Unless the Administrator shall otherwise determine, (i) uncertificated Restricted Shares
shall be accompanied by a notation on the records of the Company or the transfer agent to the effect that they are subject to forfeiture
until such Restricted Shares are vested as provided in Section 7(d) below, and (ii) certificated Restricted Shares shall
remain in the possession of the Company until such Restricted Shares are vested as provided in Section 7(d) below, and the grantee
shall be required, as a condition of the grant, to deliver to the Company such instruments of transfer as the Administrator may prescribe.

 

(c)            Restrictions.
Restricted Shares may not be sold, assigned, transferred, pledged or otherwise encumbered or disposed of except as specifically provided
herein or in the Restricted Stock Award Certificate. Except as may otherwise be provided by the Administrator either in the Award Certificate
or, subject to Section 16 below, in writing after the Award is issued, if a grantee’s employment (or other Service Relationship)
with the Company and its Subsidiaries terminates for any reason, any Restricted Shares that have not vested at the time of termination
shall automatically and without any requirement of notice to such grantee from or other action by or on behalf of, the Company be deemed
to have been reacquired by the Company at its original purchase price (if any) from such grantee or such grantee’s legal representative
simultaneously with such termination of employment (or other Service Relationship), and thereafter shall cease to represent any ownership
of the Company by the grantee or rights of the grantee as a stockholder. Following such deemed reacquisition of Restricted Shares that
are represented by physical certificates, a grantee shall surrender such certificates to the Company upon request without consideration.

 

(d)            Vesting
of Restricted Shares. The Administrator at the time of grant shall specify the date or dates and/or the attainment of pre-established
performance goals, objectives and other conditions on which the non-transferability of the Restricted Shares and the Company’s right
of repurchase or forfeiture shall lapse. Subsequent to such date or dates and/or the attainment of such pre-established performance goals,
objectives and other conditions, the shares on which all restrictions have lapsed shall no longer be Restricted Shares and shall be deemed
 “vested.”

 

SECTION 8. RESTRICTED
STOCK UNITS

 

(a)            Nature
of Restricted Stock Units. The Administrator may grant Restricted Stock Units under the Plan. A Restricted Stock Unit is an Award
of stock units that may be settled in shares of Stock (or cash, to the extent explicitly provided for in the Award Certificate) upon the
satisfaction of such restrictions and conditions at the time of grant. Conditions may be based on continuing employment (or other Service
Relationship) and/or achievement of pre-established performance goals and objectives. The terms and conditions of each such Award shall
be determined by the Administrator, and such terms and conditions may differ among individual Awards and grantees. Except in the case
of Restricted Stock Units with a deferred settlement date that complies with Section 409A, at the end of the vesting period, the
Restricted Stock Units, to the extent vested, shall be settled in the form of shares of Stock. Restricted Stock Units with deferred settlement
dates are subject to Section 409A and shall contain such additional terms and conditions as the Administrator shall determine in
its sole discretion in order to comply with the requirements of Section 409A.

 

    11

     

    

 

(b)           Election
to Receive Restricted Stock Units in Lieu of Compensation. The Administrator may, in its sole discretion, permit a grantee to elect
to receive a portion of future cash compensation otherwise due to such grantee in the form of an award of Restricted Stock Units. Any
such election shall be made in writing and shall be delivered to the Company no later than the date specified by the Administrator and
in accordance with Section 409A and such other rules and procedures established by the Administrator. Any such future cash compensation
that the grantee elects to defer shall be converted to a fixed number of Restricted Stock Units based on the Fair Market Value of Stock
on the date the compensation would otherwise have been paid to the grantee if such payment had not been deferred as provided herein. The
Administrator shall have the sole right to determine whether and under what circumstances to permit such elections and to impose such
limitations and other terms and conditions thereon as the Administrator deems appropriate. Any Restricted Stock Units that are elected
to be received in lieu of cash compensation shall be fully vested, unless otherwise provided in the Award Certificate.

 

(c)            Rights
as a Stockholder. A grantee shall have the rights as a stockholder only as to shares of Stock acquired by the grantee upon settlement
of Restricted Stock Units; provided, however, that the grantee may be credited with Dividend Equivalent Rights with respect to the stock
units underlying his or her Restricted Stock Units, subject to the provisions of Section 11 and such terms and conditions as the
Administrator may determine.

 

(d)           Termination.
Except as may otherwise be provided by the Administrator either in the Award Certificate or, subject to Section 16 below, in writing
after the Award is issued, a grantee’s right in all Restricted Stock Units that have not vested shall automatically terminate upon
the grantee’s termination of employment (or cessation of Service Relationship) with the Company and its Subsidiaries for any reason.

 

SECTION 9. UNRESTRICTED
STOCK AWARDS

 

Grant or Sale of Unrestricted Stock. The
Administrator may grant (or sell at par value or such higher purchase price determined by the Administrator) an Unrestricted Stock Award
under the Plan. An Unrestricted Stock Award is an Award pursuant to which the grantee may receive shares of Stock free of any restrictions
under the Plan. Unrestricted Stock Awards may be granted in respect of past services or other valid consideration, or in lieu of cash
compensation due to such grantee.

 

SECTION 10. CASH-BASED
AWARDS

 

Grant of Cash-Based Awards. The Administrator
may grant Cash-Based Awards under the Plan. A Cash-Based Award is an Award that entitles the grantee to a payment in cash upon the attainment
of specified performance goals. The Administrator shall determine the maximum duration of the Cash-Based Award, the amount of cash to
which the Cash-Based Award pertains, the conditions upon which the Cash-Based Award shall become vested or payable, and such other provisions
as the Administrator shall determine. Each Cash-Based Award shall specify a cash-denominated payment amount, formula or payment ranges
as determined by the Administrator. Payment, if any, with respect to a Cash-Based Award shall be made in accordance with the terms of
the Award and may be made in cash.

 

    12

     

    

 

SECTION 11. DIVIDEND
EQUIVALENT RIGHTS

 

(a)            Dividend
Equivalent Rights. The Administrator may grant Dividend Equivalent Rights under the Plan. A Dividend Equivalent Right is an Award
entitling the grantee to receive credits based on cash dividends that would have been paid on the shares of Stock specified in the Dividend
Equivalent Right (or other Award to which it relates) if such shares had been issued to the grantee. A Dividend Equivalent Right may be
granted hereunder to any grantee as a component of an award of Restricted Stock Units or as a freestanding award. The terms and conditions
of Dividend Equivalent Rights shall be specified in the Award Certificate. Dividend equivalents credited to the holder of a Dividend Equivalent
Right may be paid currently or may be deemed to be reinvested in additional shares of Stock, which may thereafter accrue additional equivalents.
Any such reinvestment shall be at Fair Market Value on the date of reinvestment or such other price as may then apply under a dividend
reinvestment plan sponsored by the Company, if any. Dividend Equivalent Rights may be settled in cash or shares of Stock or a combination
thereof, in a single installment or installments. A Dividend Equivalent Right granted as a component of an Award of Restricted Stock Units
shall provide that such Dividend Equivalent Right shall be settled only upon settlement or payment of, or lapse of restrictions on, such
other Award, and that such Dividend Equivalent Right shall expire or be forfeited or annulled under the same conditions as such other
Award.

 

(b)            Termination.
Except as may otherwise be provided by the Administrator either in the Award Certificate or, subject to Section 16 below, in writing
after the Award is issued, a grantee’s rights in all Dividend Equivalent Rights shall automatically terminate upon the grantee’s
termination of employment (or cessation of Service Relationship) with the Company and its Subsidiaries for any reason.

 

SECTION 12. Transferability
of Awards

 

(a)            Transferability.
Except as provided in Section 12(b) below, during a grantee’s lifetime, his or her Awards shall be exercisable only by
the grantee, or by the grantee’s legal representative or guardian in the event of the grantee’s incapacity. No Awards shall
be sold, assigned, transferred or otherwise encumbered or disposed of by a grantee other than by will or by the laws of descent and distribution
or pursuant to a domestic relations order, at the Administrator’s discretion and in compliance with applicable law. No Awards shall
be subject, in whole or in part, to attachment, execution, or levy of any kind, and any purported transfer in violation hereof shall be
null and void.

 

(b)            Administrator
Action. Notwithstanding Section 12(a), the Administrator, in its discretion, may provide either in the Award Certificate regarding
a given Award or by subsequent written approval that the grantee (who is an employee or director) may transfer his or her Non-Qualified
Stock Options to his or her immediate family members, to trusts for the benefit of such family members, or to partnerships in which such
family members are the only partners, provided that the transferee agrees in writing with the Company to be bound by all of the terms
and conditions of this Plan and the applicable Award. In no event may an Award be transferred by a grantee for value.

 

    13

     

    

 

(c)            Family
Member. For purposes of Section 12(b), “family member” shall mean a grantee’s child, stepchild, grandchild,
parent, stepparent, grandparent, 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 grantee’s household (other than a tenant
of the grantee), a trust in which these persons (or the grantee) have more than 50 percent of the beneficial interest, a foundation in
which these persons (or the grantee) control the management of assets, and any other entity in which these persons (or the grantee) own
more than 50 percent of the voting interests.

 

(d)           Designation
of Beneficiary. To the extent permitted by the Company, each grantee to whom an Award has been made under the Plan may designate a
beneficiary or beneficiaries to exercise any Award or receive any payment under any Award payable on or after the grantee’s death.
Any such designation shall be on a form provided for that purpose by the Administrator and shall not be effective until received by the
Administrator. If no beneficiary has been designated by a deceased grantee, or if the designated beneficiaries have predeceased the grantee,
the beneficiary shall be the grantee’s estate.

 

SECTION 13. TAX
WITHHOLDING

 

(a)            Payment
by Grantee. Each grantee shall, no later than the date as of which the value of an Award or of any Stock or other amounts received
thereunder first becomes includable in the gross income of the grantee for income tax purposes, pay to the Company, or make arrangements
satisfactory to the Administrator regarding payment of, any Federal, state, or local taxes of any kind required by law to be withheld
by the Company with respect to such income. The Company and its Subsidiaries shall, to the extent permitted by law, have the right to
deduct any such taxes from any payment of any kind otherwise due to the grantee. The Company’s obligation to deliver evidence of
book entry (or stock certificates) to any grantee is subject to and conditioned on tax withholding obligations being satisfied by the
grantee.

 

(b)            Payment
in Stock. The Administrator may require the Company’s tax withholding obligation to be satisfied, in whole or in part, by the
Company withholding from shares of Stock to be issued pursuant to any Award a number of shares with an aggregate Fair Market Value (as
of the date the withholding is effected) that would satisfy the withholding amount due; provided, however, that the amount withheld does
not exceed the maximum statutory tax rate or such lesser amount as is necessary to avoid liability accounting treatment. For purposes
of share withholding, the Fair Market Value of withheld shares shall be determined in the same manner as the value of Stock includible
in income of the grantees. The Administrator may also require the Company’s tax withholding obligation to be satisfied, in whole
or in part, by an arrangement whereby a certain number of shares of Stock issued pursuant to any Award are immediately sold and proceeds
from such sale are remitted to the Company in an amount that would satisfy the withholding amount due.

 

    14

     

    

 

SECTION 14. Section 409A
awards

 

Awards are intended to be exempt from Section 409A
to the greatest extent possible and to otherwise comply with Section 409A. The Plan and all Awards shall be interpreted in accordance
with such intent. To the extent that any Award is determined to constitute “nonqualified deferred compensation” within the
meaning of Section 409A (a “409A Award”), the Award shall be subject to such additional rules and requirements
as specified by the Administrator from time to time in order to comply with Section 409A. In this regard, if any amount under a 409A
Award is payable upon a “separation from service” (within the meaning of Section 409A) to a grantee who is then considered
a “specified employee” (within the meaning of Section 409A), then no such payment shall be made prior to the date that
is the earlier of (i) six months and one day after the grantee’s separation from service, or (ii) the grantee’s
death, but only to the extent such delay is necessary to prevent such payment from being subject to interest, penalties and/or additional
tax imposed pursuant to Section 409A. Further, the settlement of any 409A Award may not be accelerated except to the extent permitted
by Section 409A.

 

SECTION 15. TERMINATION
OF SERVICE RELATIONSHIP, TRANSFER, LEAVE OF ABSENCE, ETC.

 

(a)            Termination
of Service Relationship. If the grantee’s Service Relationship is with an Affiliate and such Affiliate ceases to be an Affiliate,
the grantee shall be deemed to have terminated his or her Service Relationship for purposes of the Plan.

 

(b)            For
purposes of the Plan, the following events shall not be deemed a termination of a Service Relationship:

 

(i)            a
transfer to the employment of the Company from an Affiliate or from the Company to an Affiliate, or from one Affiliate to another; or

 

(ii)           an
approved leave of absence for military service or sickness, or for any other purpose approved by the Company, if the employee’s
right to re-employment is guaranteed either by a statute or by contract or under the policy pursuant to which the leave of absence was
granted or if the Administrator otherwise so provides in writing.

 

SECTION 16. AMENDMENTS
AND TERMINATION

 

The Board may, at any time, amend or discontinue
the Plan and the Administrator may, at any time, amend or cancel any outstanding Award for the purpose of satisfying changes in law or
for any other lawful purpose, but no such action shall materially and adversely affect rights under any outstanding Award without the
holder’s consent. The Administrator is specifically authorized to exercise its discretion to reduce the exercise price of outstanding
Stock Options or Stock Appreciation Rights or effect the repricing of such Awards through cancellation and re-grants. To the extent required
under the rules of any securities exchange or market system on which the Stock is listed, to the extent determined by the Administrator
to be required by the Code to ensure that Incentive Stock Options granted under the Plan are qualified under Section 422 of the Code,
Plan amendments shall be subject to approval by Company stockholders. Nothing in this Section 16 shall limit the Administrator’s
authority to take any action permitted pursuant to Section 3(b) or 3(c).

 

    15

     

    

 

SECTION 17. STATUS
OF PLAN

 

With respect to the portion of any Award that has
not been exercised and any payments in cash, Stock or other consideration not received by a grantee, a grantee shall have no rights greater
than those of a general creditor of the Company unless the Administrator shall otherwise expressly determine in connection with any Award
or Awards. In its sole discretion, the Administrator may authorize the creation of trusts or other arrangements to meet the Company’s
obligations to deliver Stock or make payments with respect to Awards hereunder, provided that the existence of such trusts or other arrangements
is consistent with the foregoing sentence.

 

SECTION 18. GENERAL
PROVISIONS

 

(a)            No
Distribution. The Administrator may require each person acquiring Stock pursuant to an Award to represent to and agree with the Company
in writing that such person is acquiring the shares without a view to distribution thereof.

 

(b)           Issuance
of Stock. To the extent certificated, stock certificates to grantees under this Plan shall be deemed delivered for all purposes when
the Company or a stock transfer agent of the Company shall have mailed such certificates in the United States mail, addressed to the grantee,
at the grantee’s last known address on file with the Company. Uncertificated Stock shall be deemed delivered for all purposes when
the Company or a Stock transfer agent of the Company shall have given to the grantee by electronic mail (with proof of receipt) or by
United States mail, addressed to the grantee, at the grantee’s last known address on file with the Company, notice of issuance and
recorded the issuance in its records (which may include electronic “book entry” records). Notwithstanding anything herein
to the contrary, the Company shall not be required to issue or deliver any evidence of book entry or certificates evidencing shares of
Stock pursuant to the exercise or settlement of any Award, unless and until the Administrator has determined, with advice of counsel (to
the extent the Administrator deems such advice necessary or advisable), that the issuance and delivery is in compliance with all applicable
laws, regulations of governmental authorities and, if applicable, the requirements of any exchange on which the shares of Stock are listed,
quoted or traded. Any Stock issued pursuant to the Plan shall be subject to any stop-transfer orders and other restrictions as the Administrator
deems necessary or advisable to comply with federal, state or foreign jurisdiction, securities or other laws, rules and quotation
system on which the Stock is listed, quoted or traded. The Administrator may place legends on any Stock certificate or notations on any
book entry to reference restrictions applicable to the Stock. In addition to the terms and conditions provided herein, the Administrator
may require that an individual make such reasonable covenants, agreements, and representations as the Administrator, in its discretion,
deems necessary or advisable in order to comply with any such laws, regulations, or requirements. The Administrator shall have the right
to require any individual to comply with any timing or other restrictions with respect to the settlement or exercise of any Award, including
a window-period limitation, as may be imposed in the discretion of the Administrator.

 

(c)            Stockholder
Rights. Until Stock is deemed delivered in accordance with Section 18(b), no right to vote or receive dividends or any other
rights of a stockholder will exist with respect to shares of Stock to be issued in connection with an Award, notwithstanding the exercise
of a Stock Option or any other action by the grantee with respect to an Award.

 

    16

     

    

 

(d)            Other
Compensation Arrangements; No Employment Rights. Nothing contained in this Plan shall prevent the Board from adopting other or additional
compensation arrangements, including trusts, and such arrangements may be either generally applicable or applicable only in specific cases.
The adoption of this Plan and the grant of Awards do not confer upon any employee any right to continued employment with the Company or
any Subsidiary.

 

(e)            Trading
Policy Restrictions. Option exercises and other Awards under the Plan shall be subject to the Company’s insider trading policies
and procedures, as in effect from time to time.

 

(f)            Clawback
Policy. Awards under the Plan shall be subject to the Company’s clawback policy, as in effect from time to time.

 

SECTION 19. EFFECTIVE
DATE OF PLAN

 

This Plan shall become effective upon the Closing
Date following stockholder approval in accordance with applicable state law, the Company’s bylaws and articles of incorporation,
and applicable stock exchange rules. No grants of Stock Options and other Awards may be made hereunder after the tenth anniversary of
the Effective Date and no grants of Incentive Stock Options may be made hereunder after the tenth anniversary of the date the Plan is
approved by the Board.

 

SECTION 20. GOVERNING
LAW

 

This Plan and all Awards and actions taken thereunder
shall be governed by, and construed in accordance with, the General Corporation Law of the State of Delaware as to matters within the
scope thereof, and as to all other matters shall be governed by and construed in accordance with the internal laws of Commonwealth of
Massachusetts, applied without regard to conflict of law principles.

Article II

Registrations and Offerings

 

2.1          Shelf
Registration

 

2.1.1       Filing.
The Company shall file within thirty (30) days after the Closing Date, and use commercially reasonable efforts to cause to be declared
effective as soon as practicable thereafter, a Registration Statement for a Shelf Registration on Form S-1 (the “Form S-1
Shelf”) or, if the Company is eligible to use a Registration Statement on Form S-3, a Shelf Registration on Form S-3
(the “Form S-3 Shelf”), in each case, covering the resale of all the Registrable Securities (determined
as of two business days prior to such filing) on a delayed or continuous basis and shall use its commercially reasonable efforts to have
such Shelf declared effective as soon as practicable after the filing thereof, but no later than the earlier of (a) the 90th
calendar day (or as soon as reasonably practicable if the SEC notifies the Company that it will “review” the Registration
Statement) following the Closing and (ii) the 10th business day after the date the Company is notified (orally or in writing, whichever
is earlier) by the SEC that the Registration Statement will not be “reviewed” or will not be subject to further review. Such
Shelf shall provide for the resale of the Registrable Securities included therein pursuant to any method or combination of methods legally
available (the “Plan of Distribution”) to, and requested by, any Holder named therein. The Company shall maintain
a Shelf in accordance with the terms hereof, and shall prepare and file with the SEC such amendments, including post-effective amendments,
and supplements as may be necessary to keep a Shelf continuously effective, available for use and in compliance with the provisions of
the Securities Act until such time as there are no longer any Registrable Securities. In the event the Company files a Form S-1
Shelf, the Company shall use its commercially reasonable efforts to convert the Form S-1 Shelf (and any Subsequent Shelf Registration)
to a Form S-3 Shelf as soon as practicable after the Company is eligible to use Form S-3.

 

    5

     

    

 

2.1.2       Subsequent
Shelf Registration. If any Shelf ceases to be effective under the Securities Act for any reason at any time while Registrable Securities
are still outstanding, the Company shall, subject to Section 3.3, use its commercially reasonable efforts to as promptly
as is reasonably practicable cause such Shelf to again become effective under the Securities Act (including obtaining the prompt withdrawal
of any order suspending the effectiveness of such Shelf), and shall use its commercially reasonable efforts to as promptly as is reasonably
practicable amend such Shelf in a manner reasonably expected to result in the withdrawal of any order suspending the effectiveness of
such Shelf or file an additional registration statement as a Shelf Registration (a “Subsequent Shelf Registration”)
registering the resale of all Registrable Securities (determined as of two business days prior to such filing), and pursuant to any method
or combination of methods legally available to, and requested by, any Holder named therein. If a Subsequent Shelf Registration is filed,
the Company shall use its commercially reasonable efforts to (i) cause such Subsequent Shelf Registration to become effective under
the Securities Act as promptly as is reasonably practicable after the filing thereof (it being agreed that the Subsequent Shelf Registration
shall be an automatic shelf registration statement (as defined in Rule 405 promulgated under the Securities Act) if the Company
is a well-known seasoned issuer (as defined in Rule 405 promulgated under the Securities Act) at the most recent applicable eligibility
determination date) and (ii) keep such Subsequent Shelf Registration continuously effective, available for use and in compliance
with the provisions of the Securities Act until such time as there are no longer any Registrable Securities. Any such Subsequent Shelf
Registration shall be on Form S-3 to the extent that the Company is eligible to use such form. Otherwise, such Subsequent Shelf
Registration shall be on another appropriate form.

 

2.1.3      Additional
Registrable Securities. In the event that any Holder holds Registrable Securities that are not registered for resale on a delayed
or continuous basis, the Company, upon request of a Markforged Equityholder (which for this purpose shall include affiliated entities)
or one or more Sponsor Holders, in each case that holds collectively at least ten (10.0%) percent of the Registrable Securities, shall
promptly use its commercially reasonable efforts to cause the resale of such Registrable Securities to be covered by either, at the Company’s
option, the Shelf (including by means of a post-effective amendment) or a Subsequent Shelf Registration and cause the same to become
effective as soon as practicable after such filing and such Shelf or Subsequent Shelf Registration shall be subject to the terms hereof;
provided, however, that the Company shall only be required to cause such Registrable Securities to be so covered twice
per calendar year for the Markforged Equityholders and the Sponsor Holders, respectively.

 

2.1.4       Requests
for Underwritten Shelf Takedowns. At any time and from time to time when an effective Shelf is on file with the Commission, any Markforged
Equityholder or one or more Sponsor Holders (any of the Markforged Equityholders or the Sponsor Holders being, in such case, a “Demanding
Holder”) may request to sell all or any portion of its Registrable Securities in an Underwritten Offering or other coordinated
offering that is registered pursuant to the Shelf (each, an “Underwritten Shelf Takedown”); provided
that the Company shall only be obligated to effect an Underwritten Shelf Takedown if such offering shall include Registrable Securities
proposed to be sold by the Demanding Holder(s) with a total offering price reasonably expected to exceed, in the aggregate, $50,000,000
or all of such Demanding Holder’s remaining Registrable Securities (the “Minimum Takedown Threshold”).
All requests for Underwritten Shelf Takedowns shall be made by giving written notice to the Company, which shall specify the approximate
number of Registrable Securities proposed to be sold in the Underwritten Shelf Takedown. Subject to Section 2.4.4, the initial
Demanding Holder shall have the right to select the Underwriters for such offering (which shall consist of one or more reputable nationally
recognized investment banks), subject to the Company’s prior approval (which shall not be unreasonably withheld, conditioned or
delayed). The Markforged Equityholders, on the one hand, and the Sponsor Holders, on the other hand, may each collectively demand no
more than two (2) Underwritten Shelf Takedowns pursuant to this Section 2.1.4. Notwithstanding anything to the contrary
in this Agreement, the Company may effect any Underwritten Offering pursuant to any then effective Registration Statement, including
a Form S-3, that is then available for such offering.

 

    6

     

    

 

2.1.5      Reduction
of Underwritten Offering. If the managing Underwriter or Underwriters in an Underwritten Shelf Takedown, in good faith, advises the
Company, the Demanding Holders and the Holders requesting piggy-back rights pursuant to this Agreement with respect to such Underwritten
Shelf Takedown (the “Requesting Holders”) (if any) in writing that the dollar amount or number of Registrable
Securities that the Demanding Holders and the Requesting Holders (if any) desire to sell, taken together with all other Common Stock
or other equity securities that the Company desires to sell and all Common Stock or other equity securities, if any, that have been requested
to be sold in such Underwritten Offering pursuant to separate written contractual piggy-back registration rights held by any other shareholders,
exceeds the maximum dollar amount or maximum number of equity securities that can be sold in the Underwritten Offering without adversely
affecting the proposed offering price, the timing, the distribution method, or the probability of success of such offering (such maximum
dollar amount or maximum number of such securities, as applicable, the “Maximum Number of Securities”), then
the Company shall include in such Underwritten Offering, before including any Common Stock or other equity securities proposed to be
sold by the Company or by other holders of Common Stock or other equity securities, the Registrable Securities of the Demanding Holders
and the Requesting Holders (if any) (pro rata based on the respective number of Registrable Securities that each Demanding Holder and
Requesting Holder (if any) has requested be included in such Underwritten Shelf Takedown and the aggregate number of Registrable Securities
that the Demanding Holders and Requesting Holders have requested be included in such Underwritten Shelf Takedown) that can be sold without
exceeding the Maximum Number of Securities. To facilitate the allocation of Registrable Securities in accordance with the above provisions,
the Company or the Underwriters may round the number of shares allocated to any Holder to the nearest 100 shares. The Company shall not
be required to include any Registrable Securities in such Underwritten Shelf Takedown unless the Holders accept the terms of the underwriting
as agreed upon between the Company and its Underwriters.

 

2.1.6      Withdrawal.
Prior to the filing of the applicable “red herring” prospectus or prospectus supplement used for marketing such Underwritten
Shelf Takedown, a majority-in-interest of the Demanding Holders initiating an Underwritten Shelf Takedown shall have the right to withdraw
from such Underwritten Shelf Takedown for any or no reason whatsoever upon written notification (a “Withdrawal Notice”)
to the Company and the Underwriter or Underwriters (if any) of their intention to withdraw from such Shelf Takedown; provided
that any Markforged Equityholder or Sponsor Holder may elect to have the Company continue an Underwritten Shelf Takedown if the Minimum
Takedown Threshold would still be satisfied by the Registrable Securities proposed to be sold in the Underwritten Shelf Takedown by the
Markforged Equityholders or the Sponsor Holders or any of their respective Permitted Transferees, as applicable. If withdrawn, a demand
for an Underwritten Shelf Takedown shall not constitute a demand for an Underwritten Shelf Takedown for purposes of Section 2.1.4;
provided that, if a Markforged Equityholder or a Sponsor Holder elects to continue an Underwritten Shelf Takedown pursuant to
the proviso in the immediately preceding sentence, such Underwritten Shelf Takedown shall instead count as an Underwritten Shelf Takedown
demanded by the Markforged Equityholders or the Sponsor Holders, as applicable, for purposes of Section 2.1.4. Following
the receipt of any Withdrawal Notice, the Company shall promptly forward such Withdrawal Notice to any other Holders that had elected
to participate in such Shelf Takedown. Notwithstanding anything to the contrary in this Agreement, the Company shall be responsible for
the Registration Expenses incurred in connection with a Shelf Takedown prior to its withdrawal under this Section 2.1.6.

 

    7

     

    

 

2.2          Piggyback
Registration.

 

2.2.1       Piggyback
Rights. Subject to Section 2.4.3, if the Company or any Holder proposes to conduct a registered offering of, or if the
Company proposes to file a Registration Statement under the Securities Act with respect to the Registration of, equity securities, or
securities or other obligations exercisable or exchangeable for, or convertible into equity securities, for its own account or for the
account of shareholders of the Company (or by the Company and by the shareholders of the Company including, without limitation, an Underwritten
Shelf Takedown pursuant to Section 2.1 hereof), other than a Registration Statement (or any registered offering with respect
thereto) (i) filed in connection with any employee stock option or other benefit plan, (ii) pursuant to a Registration Statement
on Form S-4 (or similar form that relates to a transaction subject to Rule 145 under the Securities Act or any successor rule thereto),
(iii) for an offering of debt that is convertible into equity securities of the Company, (iv) for a dividend reinvestment plan
or (v) for a rights offering, then the Company shall give written notice of such proposed offering to all of the Holders of Registrable
Securities as soon as practicable but not less than ten (10) days before the anticipated filing date of such Registration Statement
or, in the case of an Underwritten Offering pursuant to a Shelf Registration, the applicable “red herring” prospectus or
prospectus supplement used for marketing such offering, which notice shall (A) describe the amount and type of securities to be
included in such offering, the intended method(s) of distribution, and the name of the proposed managing Underwriter or Underwriters,
if any, in such offering, and (B) offer to all of the Holders of Registrable Securities the opportunity to include in such registered
offering such number of Registrable Securities as such Holders may request in writing within five (5) days after receipt of such
written notice (such registered offering, a “Piggyback Registration”). The rights provided under this Section 2.2
shall not be available to any Holder at such time as (i) there is an effective Shelf Registration Statement available for the resale
of the Registrable Securities pursuant to Section 2.1, (ii) such Registration is solely to be used for the offering of securities
by the Company for its own account and (iii) no other shareholder of the Company is entitled to participate in such Registration.
Subject to Section 2.2.2, the Company shall, in good faith, cause such Registrable Securities to be included in such Piggyback
Registration and, if applicable, shall use its commercially reasonable efforts to cause the managing Underwriter or Underwriters of such
Piggyback Registration to permit the Registrable Securities requested by the Holders pursuant to this Section 2.2.1 to be
included therein on the same terms and conditions as any similar securities of the Company included in such registered offering and to
permit the sale or other disposition of such Registrable Securities in accordance with the intended method(s) of distribution thereof.
The inclusion of any Holder’s Registrable Securities in a Piggyback Registration shall be subject to such Holder’s agreement
to enter into an underwriting agreement in customary form with the Underwriter(s) selected for such Underwritten Offering.

 

2.2.2      Reduction
of Piggyback Registration. If the managing Underwriter or Underwriters in an Underwritten Offering that is to be a Piggyback Registration,
in good faith, advises the Company and the Holders of Registrable Securities participating in the Piggyback Registration in writing that
the dollar amount or number of Common Stock or other equity securities that the Company desires to sell, taken together with (i) the
Common Stock or other equity securities, if any, as to which Registration or a registered offering has been demanded pursuant to separate
written contractual arrangements with persons or entities other than the Holders of Registrable Securities hereunder, (ii) the Registrable
Securities as to which registration has been requested pursuant to Section 2.2 hereof, and (iii) the Common Stock or
other equity securities, if any, as to which Registration or a registered offering has been requested pursuant to separate written contractual
piggy-back registration rights of other shareholders of the Company, exceeds the Maximum Number of Securities, then:

 

    8

     

    

 

(a)          If
the Registration or registered offering is undertaken for the Company’s account, the Company shall include in any such Registration
or registered offering (A) first, the Common Stock or other equity securities that the Company desires to sell, which can be sold
without exceeding the Maximum Number of Securities; (B) second, to the extent that the Maximum Number of Securities has not been
reached under the foregoing clause (A), the Registrable Securities of Holders exercising their rights to register their Registrable Securities
pursuant to Section 2.2.1, pro rata, based on the respective number of Registrable Securities that each Holder has
requested be included in such Underwritten Offering and the aggregate number of Registrable Securities that the Holders have requested
to be included in such Underwritten Offering, which can be sold without exceeding the Maximum Number of Securities; and (C) third,
to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A) and (B), the Common Stock
or other equity securities, if any, as to which Registration or a registered offering has been requested pursuant to written contractual
piggy-back registration rights of other shareholders of the Company, which can be sold without exceeding the Maximum Number of Securities;

 

(b)          If
the Registration or registered offering is pursuant to a request by persons or entities other than the Holders of Registrable Securities,
then the Company shall include in any such Registration or registered offering (A) first, the Common Stock or other equity securities,
if any, of such requesting persons or entities, other than the Holders of Registrable Securities, which can be sold without exceeding
the Maximum Number of Securities; (B) second, to the extent that the Maximum Number of Securities has not been reached under the
foregoing clause (A), the Registrable Securities of Holders exercising their rights to register their Registrable Securities pursuant
to Section 2.2.1, pro rata, based on the respective number of Registrable Securities that each Holder has requested
be included in such Underwritten Offering and the aggregate number of Registrable Securities that the Holders have requested to be included
in such Underwritten Offering, which can be sold without exceeding the Maximum Number of Securities; (C) third, to the extent that
the Maximum Number of Securities has not been reached under the foregoing clauses (A) and (B), the Common Stock or other equity
securities that the Company desires to sell, which can be sold without exceeding the Maximum Number of Securities; and (D) fourth,
to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A), (B) and (C), the Common
Stock or other equity securities for the account of other persons or entities that the Company is obligated to register pursuant to separate
written contractual arrangements with such persons or entities, which can be sold without exceeding the Maximum Number of Securities;
and

 

(c)         If
the Registration or registered offering is pursuant to a request by Holder(s) of Registrable Securities pursuant to Section 2.1
hereof, then the Company shall include in any such Registration or registered offering securities pursuant to Section 2.1.5.

 

2.2.3       Piggyback
Registration Withdrawal. Any Holder of Registrable Securities (other than a Demanding Holder, whose right to withdrawal from an Underwritten
Shelf Takedown, and related obligations, shall be governed by Section 2.1.6) shall have the right to withdraw from a Piggyback
Registration for any or no reason whatsoever upon written notification to the Company and the Underwriter or Underwriters (if any) of
his, her or its intention to withdraw from such Piggyback Registration prior to the effectiveness of the Registration Statement filed
with the Commission with respect to such Piggyback Registration or, in the case of a Piggyback Registration pursuant to a Shelf Registration,
the filing of the applicable “red herring” prospectus or prospectus supplement with respect to such Piggyback Registration
used for marketing such transaction. The Company (whether on its own good faith determination or as the result of a request for withdrawal
by persons pursuant to separate written contractual obligations) may withdraw a Registration Statement filed with the Commission in connection
with a Piggyback Registration (which, in no circumstance, shall include the Shelf) at any time prior to the effectiveness of such Registration
Statement. Notwithstanding anything to the contrary in this Agreement (other than Section 2.1.6), the Company shall be responsible
for the Registration Expenses incurred in connection with the Piggyback Registration prior to its withdrawal under this Section 2.2.3.

 

    9

     

    

 

2.2.4       Unlimited
Piggyback Registration Rights. For purposes of clarity, subject to Section 2.1.6, any Piggyback Registration effected
pursuant to Section 2.2 hereof shall not be counted as a demand for an Underwritten Shelf Takedown under Section 2.1.4
hereof.

 

2.3            Market
Stand-off. In connection with any Underwritten Offering of equity securities of the Company (other than a Block Trade), each Holder
that participates in the Underwritten Offering pursuant to the terms of this Agreement agrees that it shall not Transfer any Common Stock
or other equity securities of the Company (other than those included in such offering pursuant to this Agreement), without the prior
written consent of the Company, during the 90-day period beginning on the date of pricing of such offering or such shorter period during
which the Company agrees not to conduct an underwritten primary offering of Common Stock or other equity securities, except in the event
the Underwriters managing the offering otherwise agree by written consent. Each such participating Holder agrees to execute a customary
lock-up agreement in favor of the Underwriters to such effect (in each case on substantially the same terms and conditions as all such
Holders).

 

2.4         Block
Trades.

 

2.4.1       Notwithstanding
the foregoing, at any time and from time to time when an effective Shelf is on file with the Commission and effective, if a Demanding
Holder or Demanding Holders wishes to engage in a Block Trade, with a total offering price reasonably expected to exceed, in the aggregate,
either (x) $75,000,000 or (y) all remaining Registrable Securities held by the Demanding Holder, then notwithstanding the time
periods provided for in Section 2.1.4, such Demanding Holder need only to notify the Company of the Block Trade at least
five (5) business days prior to the day such offering is to commence and the Company shall as expeditiously as possible use its
commercially reasonable efforts to facilitate such Block Trade; provided that the Demanding Holders representing a majority of
the Registrable Securities wishing to engage in the Block Trade shall use commercially reasonable efforts to work with the Company and
any Underwriters prior to making such request in order to facilitate preparation of the registration statement, prospectus and other
offering documentation related to the Block Trade.

 

2.4.2       Prior
to the filing of the applicable “red herring” prospectus or prospectus supplement used in connection with a Block Trade,
a majority-in-interest of the Demanding Holders initiating such Block Trade shall have the right to submit a Withdrawal Notice to the
Company and the Underwriter or Underwriters (if any) of their intention to withdraw from such Block Trade. Notwithstanding anything to
the contrary in this Agreement, the Company shall be responsible for the Registration Expenses incurred in connection with a block trade
prior to its withdrawal under this Section 2.4.2.

 

2.4.3       Notwithstanding
anything to the contrary in this Agreement, Section 2.2 hereof shall not apply to a Block Trade initiated by a Demanding
Holder pursuant to this Agreement.

 

2.4.4       The
Demanding Holder in a Block Trade shall have the right to select the Underwriters for such Block Trade (which shall consist of one or
more reputable nationally recognized investment banks).

Article III

Company Procedures

 

3.1          General
Procedures. In connection with any Shelf and/or Shelf Takedown, the Company shall use its commercially reasonable efforts to effect
such Registration to permit the sale of such Registrable Securities in accordance with the intended plan of distribution thereof, and
pursuant thereto the Company shall, as expeditiously as possible:

 

3.1.1       prepare
and file with the Commission as soon as practicable a Registration Statement with respect to such Registrable Securities and use its
reasonable best efforts to cause such Registration Statement to become effective and remain effective until all Registrable Securities
have ceased to be Registrable Securities;

 

3.1.2       prepare
and file with the Commission such amendments and post-effective amendments to the Registration Statement, and such supplements to the
Prospectus, as may be reasonably requested by any Holder that holds at least five (5.0%) percent of the Registrable Securities registered
on such Registration Statement or any Underwriter of Registrable Securities or as may be required by the rules, regulations or instructions
applicable to the registration form used by the Company or by the Securities Act or rules and regulations thereunder to keep the
Registration Statement effective until all Registrable Securities covered by such Registration Statement are sold in accordance with
the intended plan of distribution set forth in such Registration Statement or supplement to the Prospectus;

 

3.1.3       prior
to filing a Registration Statement or Prospectus, or any amendment or supplement thereto, furnish without charge to the Underwriters,
if any, and the Holders of Registrable Securities included in such Registration, and such Holders’ legal counsel, copies of such
Registration Statement as proposed to be filed, each amendment and supplement to such Registration Statement (in each case including
all exhibits thereto and documents incorporated by reference therein), the Prospectus included in such Registration Statement (including
each preliminary Prospectus), and such other documents as the Underwriters and the Holders of Registrable Securities included in such
Registration or the legal counsel for any such Holders may request in order to facilitate the disposition of the Registrable Securities
owned by such Holders;

 

3.1.4       prior
to any public offering of Registrable Securities (i) register or qualify the Registrable Securities covered by the Registration
Statement under such securities or “blue sky” laws of such jurisdictions in the United States as the Holders
of Registrable Securities included in such Registration Statement (in light of their intended plan of distribution) may request (or provide
evidence satisfactory to such Holders that the Registrable Securities are exempt from such registration or qualification) and (ii) take
such action necessary to cause such Registrable Securities covered by the Registration Statement to be registered with or approved by
such other governmental authorities as may be necessary by virtue of the business and operations of the Company and do any and all other
acts and things that may be necessary or advisable to enable the Holders of Registrable Securities included in such Registration Statement
to consummate the disposition of such Registrable Securities in such jurisdictions; provided, however, that the Company
shall not be required to qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify or
take any action to which it would be subject to general service of process or taxation in any such jurisdiction where it is not then
otherwise so subject;

 

3.1.5       cause
all such Registrable Securities to be listed on each national securities exchange on which similar securities issued by the Company are

3.1.6       provide
a transfer agent or warrant agent, as applicable, and registrar for all such Registrable Securities no later than the effective date
of such Registration Statement;

 

3.1.7       advise
each seller of such Registrable Securities, promptly after it shall receive notice or obtain knowledge thereof, of the issuance of any
stop order by the Commission suspending the effectiveness of such Registration Statement or the initiation or threatening of any proceeding
for such purpose and promptly use its reasonable best efforts to prevent the issuance of any stop order or to obtain its withdrawal if
such stop order should be issued;

 

    11

     

    

 

3.1.8       at
least five (5) days prior to the filing of any Registration Statement or Prospectus or any amendment or supplement to such Registration
Statement or Prospectus (or such shorter period of time as may be necessary in order to comply with the Securities Act, the Exchange
Act, and the rules and regulations promulgated under the Securities Act or Exchange Act, as applicable), furnish a copy thereof
to each seller of such Registrable Securities or its counsel (excluding any exhibits thereto and any filing made under the Exchange Act
that is to be incorporated by reference therein);

 

3.1.9       notify
the Holders at any time when a Prospectus relating to such Registration Statement is required to be delivered under the Securities Act,
of the happening of any event as a result of which the Prospectus included in such Registration Statement, as then in effect, includes
a Misstatement, and then to correct such Misstatement as set forth in Section 3.3 hereof;

 

3.1.10     permit
a representative of any Holder, the Underwriters, if any, and any attorney or accountant retained by such Holder(s) or Underwriter
to participate, at each such person’s own expense, in the preparation of the Registration Statement, and cause the Company’s
officers, directors and employees to supply all information reasonably requested by any such representative, Underwriter, attorney or
accountant in connection with the Registration; provided, however, that such representatives or Underwriters agree to confidentiality
arrangements reasonably satisfactory to the Company, prior to the release or disclosure of any such information;

 

3.1.11     obtain
a “comfort” letter from the Company’s independent registered public accountants in the event of an Underwritten Offering
or other coordinated offering that is registered pursuant to a Registration Statement, in customary form and covering such matters of
the type customarily covered by “comfort” letters as the managing Underwriter or other similar type of sales agent or placement
agent may reasonably request, and reasonably satisfactory to a majority-in-interest of the participating Holders;

 

3.1.12     on
the date the Registrable Securities are delivered for sale pursuant to such Registration, obtain an opinion, dated such date, of counsel
representing the Company for the purposes of such Registration, addressed to the Holders, the placement agent or sales agent, if any,
and the Underwriters, if any, covering such legal matters with respect to the Registration in respect of which such opinion is being
given as the Holders, placement agent, sales agent, or Underwriter may reasonably request and as are customarily included in such opinions
and negative assurance letters, and reasonably satisfactory to a majority-in-interest of the participating Holders;

 

3.1.13     in
the event of any Underwritten Offering or other coordinated offering that is registered pursuant to a Registration Statement, enter into
and perform its obligations under an underwriting agreement, sales agreement or placement agreement, in usual and customary form, with
the managing Underwriter, sales agent or placement agent of such offering;

 

3.1.14    make
available to its security holders, as soon as reasonably practicable, an earnings statement covering the period of at least twelve (12)
months beginning with the first day of the Company’s first full calendar quarter after the effective date of the Registration Statement
which satisfies the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder (or any successor rule then
in effect);

 

    12

     

    

 

 

3.1.15       if
the Registration involves the Registration of Registrable Securities involving gross proceeds in excess of $50 million with respect to
an Underwritten Offering pursuant to Section 2.1.4, use its reasonable efforts to make available senior executives of the
Company to participate in customary “road show” presentations that may be reasonably requested by the Underwriter in such
Underwritten Offering; and

 

3.1.16       otherwise,
in good faith, cooperate reasonably with, and take such customary actions as may reasonably be requested by the Holders, in connection
with such Registration.

 

Notwithstanding the foregoing,
the Company shall not be required to provide any documents or information to an Underwriter or other sales agent or placement agent if
such Underwriter or other sales agent or placement agent has not then been named with respect to the applicable Underwritten Offering
or other coordinated offering that is registered pursuant to a Registration Statement.

 

3.2          Registration
Expenses. The Registration Expenses of all Registrations shall be borne by the Company. It is acknowledged by the Holders that the
Holders shall bear all incremental selling expenses relating to the sale of Registrable Securities, such as Underwriters’ or agents’
commissions and discounts, brokerage fees, Underwriter marketing costs and, other than as set forth in the definition of “Registration
Expenses,” all reasonable fees and expenses of any legal counsel representing the Holders.

 

3.3        
Stock Distributions. In connection with any Shelf or Shelf Takedown, if the Company shall receive a request from a Holder
of Registrable Securities to effectuate a pro rata in-kind distribution or other similar transfer for no consideration of such
Registrable Securities pursuant to such Registration to its members, partners or stockholders, as the case may be, then the Company shall
deliver or cause to be delivered to the transfer agent and registrar for the Registrable Securities an opinion of counsel to the Company
reasonably acceptable to such transfer agent and registrar that any legend referring to the Act may be removed upon such distribution
or other transfer of such Registrable Securities pursuant to such Registration, provided that the distributee or transferee of such Registrable
Securities is not and has not been for the preceding ninety (90) days an affiliate of Parent (as defined in Rule 405 promulgated
under the Act). The Company’s obligations hereunder are conditioned upon the receipt of a representation letter reasonably acceptable
to the Company from such Holder regarding such proposed pro rata in-kind distribution or other similar transfer for no consideration
of such Registrable Securities.

 

3.3          Suspension
of Sales; Adverse Disclosure; Restrictions on Registration Rights.

 

3.3.1        Upon
receipt of written notice from the Company that a Registration Statement or Prospectus contains a Misstatement, each of the Holders shall
forthwith discontinue disposition of Registrable Securities until it has received copies of a supplemented or amended Prospectus correcting
the Misstatement (it being understood that the Company hereby covenants to prepare and file such supplement or amendment as soon as practicable
after the time of such notice), or until it is advised in writing by the Company that the use of the Prospectus may be resumed.

 

3.3.2       Subject
to Section 3.3.4, if the filing, initial effectiveness or continued use of a Registration Statement in respect of any Registration
at any time would (a) require the Company to make an Adverse Disclosure, (b) require the inclusion in such Registration Statement
of financial statements that are unavailable to the Company for reasons beyond the Company’s control, or (c) in the good faith
judgment of the majority of the Board such Registration, cause serious and irreparable harm to the Company and the majority of the Board
concludes as a result that it is essential to defer such filing, initial effectiveness or continued use at such time, the Company may,
upon giving prompt written notice of such action to the Holders, delay the filing or initial effectiveness of, or suspend use of, such
Registration Statement for the shortest period of time determined in good faith by the Company to be necessary for such purpose. In the
event the Company exercises its rights under this Section 3.3.2, the Holders agree to suspend, immediately upon their receipt
of the notice referred to above, their use of the Prospectus relating to any Registration in connection with any sale or offer to sell
Registrable Securities.

 

    13

     

    

 

3.3.3         (a) During
the period starting with the date sixty (60) days prior to the Company’s good faith estimate of the date of the filing of, and
ending on a date one hundred twenty (120) days after the effective date of, a Company-initiated Registration and provided that the Company
continues to actively employ, in good faith, all reasonable efforts to maintain the effectiveness of the applicable Shelf Registration
Statement, or (b) if, pursuant to Section 2.1.4, Holders have requested an Underwritten Shelf Takedown and the Company
and such Holders are unable to obtain the commitment of underwriters to firmly underwrite such offering, the Company may, upon giving
prompt written notice of such action to the Holders, delay any other registered offering pursuant to Section 2.1.4 or 2.4.

 

3.3.4        The
right to delay or suspend any filing, initial effectiveness or continued use of a Registration Statement pursuant to Section 3.3.2
or a registered offering pursuant to Section 3.3.3 shall be exercised by the Company, in the aggregate, for not more
than ninety (90) consecutive calendar days or more than one hundred and twenty (120) total calendar days, in each case, during any twelve
(12)-month period.

 

3.4         Reporting
Obligations. As long as any Holder shall own Registrable Securities, the Company, at all times while it shall be a reporting company
under the Exchange Act, covenants to file timely (or obtain extensions in respect thereof and file within the applicable grace period)
all reports required to be filed by the Company after the date hereof pursuant to Sections 13(a) or 15(d) of the Exchange Act
and to promptly furnish the Holders with true and complete copies of all such filings; provided that any documents publicly filed
or furnished with the Commission pursuant to the Electronic Data Gathering, Analysis and Retrieval System shall be deemed to have been
furnished or delivered to the Holders pursuant to this Section 3.4. The Company further covenants that it shall take such
further action as any Holder may reasonably request, all to the extent required from time to time to enable such Holder to sell Registrable
Securities held by such Holder without registration under the Securities Act within the limitation of the exemptions provided by Rule 144
promulgated under the Securities Act (or any successor rule then in effect). Upon the request of any Holder, the Company shall deliver
to such Holder a written certification of a duly authorized officer as to whether it has complied with such requirements.

 

3.5        
Requirements for Participation in Registration Statement Underwritten Offerings. Notwithstanding anything in this Agreement to
the contrary, if any Holder does not provide the Company with its requested Holder Information, the Company may exclude such Holder’s
Registrable Securities from the applicable Registration Statement or Prospectus if the Company determines, based on the advice of counsel,
that such information is necessary to effect the registration and such Holder continues thereafter to withhold such information. No person
may participate in any Underwritten Offering or other coordinated offering for equity securities of the Company pursuant to a Registration
initiated by the Company hereunder unless such person (i) agrees to sell such person’s securities on the basis provided in
any arrangements approved by the Company and (ii) completes and executes all customary questionnaires, powers of attorney, indemnities,
lock-up agreements, underwriting or other agreements and other customary documents as may be reasonably required under the terms of such
arrangements. The exclusion of a Holder’s Registrable Securities as a result of this Section 3.3 shall not affect the
registration of the other Registrable Securities to be included in such Registration.

Article IV
 

Indemnification and Contribution

 

4.1          Indemnification.

 

4.1.1       The
Company agrees to indemnify and hold harmless, to the extent permitted by law, each Holder of Registrable Securities, its officers, directors
and agents and each person who controls such Holder (within the meaning of the Securities Act) against all losses, claims, damages, liabilities
and out-of-pocket expenses (including without limitation reasonable outside attorneys’ fees) as incurred arising out of or resulting
from any untrue or alleged untrue statement of material fact contained in any Registration Statement, Prospectus or preliminary Prospectus
or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or
necessary to make the statements therein not misleading, except insofar as the same are caused by or contained in any information or
affidavit so furnished in writing to the Company by such Holder expressly for use therein, or any violation by the Company of the Securities
Act or any rule or regulation promulgated thereunder applicable to the Company and relating to action or inaction of the Company
in connection therewith.

 

4.1.2        In
connection with any Registration Statement in which a Holder of Registrable Securities is participating, such Holder shall furnish to
the Company in writing such information and affidavits with respect to such Holder as the Company reasonably requests for use in connection
with any such Registration Statement or Prospectus (the “Holder Information”) and, to the extent permitted
by law, shall indemnify and hold harmless the Company, its directors, officers and agents and each person who controls the Company (within
the meaning of the Securities Act) against all losses, claims, damages, liabilities and out-of-pocket expenses (including without limitation
reasonable outside attorneys’ fees) as incurred arising out of or resulting from any untrue or alleged untrue statement of material
fact contained in any Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or
any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading,
but only to the extent that such untrue or alleged untrue statement or omission or alleged omission is contained in any information or
affidavit so furnished in writing by such Holder expressly for use therein; provided, however, that the obligation to indemnify
shall be several, not joint and several, among such Holders of Registrable Securities, and the liability of each such Holder of Registrable
Securities shall be in proportion to and limited to the net proceeds received by such Holder from the sale of Registrable Securities
pursuant to such Registration Statement. The Holders of Registrable Securities shall indemnify the Underwriters, their officers, directors
and each person who controls such Underwriters (within the meaning of the Securities Act) to the same extent as provided in the foregoing
with respect to indemnification of the Company.

 

4.1.3       Any
person entitled to indemnification herein shall (i) give prompt written notice to the indemnifying party of any claim with respect
to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any person’s right to indemnification
hereunder to the extent such failure has not materially prejudiced the indemnifying party) and (ii) unless in such indemnified party’s
reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit
such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense
is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its
consent (but such consent shall not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume
the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such
indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may
exist between such indemnified party and any other of such indemnified parties with respect to such claim. No indemnifying party shall,
without the consent of the indemnified party, consent to the entry of any judgment or enter into any settlement which cannot be settled
in all respects by the payment of money (and such money is so paid by the indemnifying party pursuant to the terms of such settlement)
or which settlement does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party
of a release from all liability in respect to such claim or litigation.

 

    15

     

    

 

4.1.4        The
indemnification provided for under this Agreement shall remain in full force and effect regardless of any investigation made by or on
behalf of the indemnified party or any officer, director or controlling person of such indemnified party and shall survive the transfer
of securities. The Company and each Holder of Registrable Securities participating in an offering also agrees to make such provisions
as are reasonably requested by any indemnified party for contribution to such party in the event the Company’s or such Holder’s
indemnification is unavailable for any reason.

 

4.1.5        If
the indemnification provided under Section 4.1 hereof from the indemnifying party is unavailable or insufficient to hold
harmless an indemnified party in respect of any losses, claims, damages, liabilities and out-of-pocket expenses referred to herein, then
the indemnifying party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by the indemnified
party as a result of such losses, claims, damages, liabilities and out-of-pocket expenses in such proportion as is appropriate to reflect
the relative fault of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations. The relative
fault of the indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in
question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact,
was made by, or relates to information supplied by, such indemnifying party or indemnified party, and the indemnifying party’s
and indemnified party’s relative intent, knowledge, access to information and opportunity to correct or prevent such action; provided,
however, that the liability of any Holder under this Section 4.1.5 shall be limited to the amount of the net proceeds
received by such Holder in such offering giving rise to such liability. The amount paid or payable by a party as a result of the losses
or other liabilities referred to above shall be deemed to include, subject to the limitations set forth in Sections 4.1.1, 4.1.2
and 4.1.3 above, any legal or other fees, charges or out-of-pocket expenses reasonably incurred by such party in connection
with any investigation or proceeding. The parties hereto agree that it would not be just and equitable if contribution pursuant to this
Section 4.1.5 were determined by pro rata allocation or by any other method of allocation, which does not take account
of the equitable considerations referred to in this Section 4.1.5. No person guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this Section 4.1.5
from any person who was not guilty of such fraudulent misrepresentation.

provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the law of any
jurisdiction other than the State of Delaware.

 

    17

     

    

 

5.5         Jurisdiction;
Waiver of Jury Trial.

 

5.5.1        Each
of the parties hereto irrevocably and unconditionally submits to the exclusive jurisdiction of the Chancery Court of the State of Delaware
(or, if the Chancery Court of the State of Delaware declines to accept jurisdiction, any state or federal court sitting in the Borough
of Manhattan, State of New York, New York County), for the purposes of any Action (a) arising under this Agreement or (b) in
any way connected with or related or incidental to the dealings of the parties hereto in respect of this Agreement, and irrevocably and
unconditionally waives any objection to the laying of venue of any such Action in any such court, and further irrevocably and unconditionally
waives and agrees not to plead or claim in any such court that any such Action has been brought in an inconvenient forum. Each party
hereby irrevocably and unconditionally waives, and agrees not to assert, by way of motion or as a defense, counterclaim or otherwise,
in any Action against such party (i) arising under this Agreement or (ii) in any way connected with or related or incidental
to the dealings of the parties hereto in respect of this Agreement, (A) any claim that such party is not personally subject to the
jurisdiction of the courts as described in this Section 5.5 for any reason, (B) that such party or such party’s
property is exempt or immune from the jurisdiction of any such court or from any legal process commenced in such courts (whether through
service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise) and
(C) that (x) the Action in any such court is brought against such party in an inconvenient forum, (y) the venue of such
Action against such party is improper or (z) this Agreement, or the subject matter hereof, may not be enforced against such party
in or by such courts. Each party agrees that service of any process, summons, notice or document by registered mail to such party’s
respective address set forth in Section 5.5 shall be effective service of process for any such Action.

 

5.5.2        THE
PARTIES HERETO EACH HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY RIGHT TO TRIAL BY JURY OF ANY PROCEEDING, CLAIM, DEMAND,
ACTION, OR CAUSE OF ACTION (I) ARISING UNDER THIS AGREEMENT OR UNDER ANY ANCILLARY DOCUMENT OR (II) IN ANY WAY CONNECTED WITH
OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO IN RESPECT OF THIS AGREEMENT, WHETHER NOW EXISTING OR HEREAFTER ARISING,
AND WHETHER IN CONTRACT, TORT, EQUITY, OR OTHERWISE. THE PARTIES HERETO EACH HEREBY AGREES AND CONSENTS THAT ANY SUCH PROCEEDING, CLAIM,
DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY AND THAT THE PARTIES HERETO MAY FILE AN ORIGINAL
COUNTERPART OF A COPY OF THIS AGREEMENT WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES HERETO TO THE WAIVER OF
THEIR RIGHT TO TRIAL BY JURY. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (A) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY
HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING
WAIVER, (B) EACH SUCH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (C) EACH SUCH PARTY MAKES THIS
WAIVER VOLUNTARILY AND (D) EACH SUCH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS
AND CERTIFICATIONS IN THIS SECTION 5.5.

 

5.6          Amendments
and Modifications. Upon the written consent of (a) the Company and (b) the Holders of a majority of the total Registrable
Securities as of the time of any waiver or amendment, compliance with any of the provisions, covenants and conditions set forth in this
Agreement may be waived, or any of such provisions, covenants or conditions may be amended or modified; provided, however,
that in the event any such waiver, amendment or modification would be adverse in any material respect to the material rights or obligations
hereunder of a Holder of the Registrable Securities, the written consent of such Holder will also be required; provided further
that in the event any such waiver, amendment or modification would be disproportionate and adverse in any material respect to the material
rights or obligations hereunder of a Holder, the written consent of such Holder will also be required. No course of dealing between any
Holder or the Company and any other party hereto or any failure or delay on the part of a Holder or the Company in exercising any rights
or remedies under this Agreement shall operate as a waiver of any rights or remedies of any Holder or the Company. No single or partial
exercise of any rights or remedies under this Agreement by a party shall operate as a waiver or preclude the exercise of any other rights
or remedies hereunder or thereunder by such party.

 

    18

     

    

 

5.7        Termination
of Existing Registration Rights. The registration rights granted under this Agreement shall supersede any registration, qualification
or similar rights of the Holders with respect to any shares or securities of the Company or MarkForged granted under any other agreement,
including, without limitation, the Registration and Shareholder Rights Agreement, dated as of August 17, 2020, by and among the
Company, the Sponsor and certain other equity holders of the Company, and the Third Amended and Restated Investors’ Rights Agreement,
dated as of March 13, 2019, by and among MarkForged and its stockholders party thereto, and any of such preexisting registration,
qualification or similar rights and such agreements shall be terminated and of no further force and effect.

 

5.8           Term.
This Agreement shall terminate with respect to any Holder on the date that such Holder no longer holds any Registrable Securities. The
provisions of Sections 3.2, 3.4, 5.1, 5.4, and 5.5, and Article IV shall survive any termination.

 

5.9           Holder
Information. Each Holder agrees, if requested in writing, to represent to the Company the total number of Registrable Securities
held by such Holder in order for the Company to make determinations hereunder.

 

5.10         Severability.
It is the desire and intent of the parties that the provisions of this Agreement be enforced to the fullest extent permissible under
the laws and public policies applied in each jurisdiction in which enforcement is sought. Accordingly, if any particular provision of
this Agreement shall be adjudicated by a court of competent jurisdiction to be invalid, prohibited or unenforceable for any reason, such
provision, as to such jurisdiction, shall be ineffective, without invalidating the remaining provisions of this Agreement or affecting
the validity or enforceability of this Agreement or affecting the validity or enforceability of such provision in any other jurisdiction.
Notwithstanding the foregoing, if such provision could be more narrowly drawn so as not to be invalid, prohibited or unenforceable in
such jurisdiction, it shall, as to such jurisdiction, be so narrowly drawn, without invalidating the remaining provisions of this Agreement
or affecting the validity or enforceability of such provision in any other jurisdiction.

 

5.11         Specific
Performance. Each of the parties acknowledges and agrees that the other parties would be damaged irreparably in the event any of
the provisions of this Agreement are not performed in accordance with their specific terms or otherwise are breached or violated. Accordingly,
to the fullest extent permitted by law, each of the parties agrees that, without posting bond or other undertaking, the other parties
will be entitled to an injunction or injunctions to prevent breaches or violations of the provisions of this Agreement and to enforce
specifically this Agreement and the terms and provisions hereof in any action, claim or suit in addition to any other remedy to which
it may be entitled, at law or in equity. Each party further agrees that, in the event of any action for specific performance in respect
of such breach or violation, it will not assert that the defense that a remedy at law would be adequate.
