 “2. Earn-Out Shares. 

(a) Subject to, and conditioned upon the occurrence of and effective immediately after the Effective Time, (i) 20% of the number of Company
Post-Closing Common Shares issued to the MAAC Sponsor, any Affiliate of the MAAC Sponsor, any MAAC Independent Director (as defined in the BCA) or any MAAC Independent Director Transferee (as defined in the BCA) upon the conversion of MAAC

Common Shares, the “20% Earn-Out Shares”), (ii) 10% of the number of Company Post-Closing Common Shares issued to the MAAC Sponsor, any Affiliate of the MAAC Sponsor, any MAAC
Independent Director or any MAAC Independent Director Transferee upon the conversion of MAAC Class B Shares held by him, her or it immediately prior to the Effective Time (rounded up to the nearest whole share) shall be subject to the

(b) Subject to, and conditioned upon the occurrence of and effective immediately after the Effective Time, the
Earn-Out Shares shall be unvested and subject to the restrictions and forfeiture provisions set forth in this Section 2. The Earn-Out Shares

Price” and, together with the 20% Trigger Price, the “Trigger Price”), in each case, for any 20 Trading Days within any 30 Trading Day period commencing no earlier than the Closing Date and ending no later than the fifth
(5th) anniversary of the Closing Date (the “Earn-Out End Date”); provided, however, that (i) if the Earn-Out End Date occurs on a day

vested in accordance with this Section 2(b) or Section 2(c) on or before the Earn-Out End Date will be immediately forfeited at 11:59 p.m., New York,
New York time on the Earn-Out End Date. 
 (c) In the event of a Sale (as defined below) on or prior

immediately prior to the closing of such Sale. For purposes of this Agreement, “Sale” means (A) a purchase, sale, exchange, merger, business combination or other transaction or series of related transactions in which
substantially all of the Company Post-Closing Common Shares are, directly or indirectly, converted into cash, securities or other property or non-cash consideration (other than, in the case of this clause (A),
any transaction in which the holders of Company Post-Closing Common Shares as of immediately prior to the consummation of such transaction continue to own all or substantially all of the equity securities of the Company (or any successor or parent
entity of the Company) immediately following the consummation of such transaction), (B) a direct or indirect sale, lease, exchange or other transfer (regardless of the form of the transaction) in one transaction or a series of related transactions
of a majority of the Company’s assets, as determined on a consolidated basis, to a third party or third parties acting as a “group” (as defined in Section 13(d)(3) of the Exchange Act) or (C) any transaction or series of
transactions 

  
 2 

 
that results, directly or indirectly, in the shareholders of the Company as of immediately prior to such transactions holding, in the aggregate, less than fifty percent (50%) of the voting Equity
Securities of the Company (or any successor or parent company of the Company) immediately after the consummation thereof (excluding, for the avoidance of doubt, any Earn-out Shares) (in the case of each of
clause (A), (B) or (C), whether by amalgamation, merger, consolidation, arrangement, tender offer, recapitalization, purchase, issuance, sale or transfer of Equity Securities or assets or otherwise). 

(d) Each Shareholder agrees that he, she or it shall not engage in any Sale Transaction (as defined in the applicable Lock-Up Agreement) with respect to any of his, her or its Earn-Out Shares until such time as the Earn-Out Shares have vested pursuant
to Section 2(b) or Section 2(c). Notwithstanding the foregoing or anything to the contrary herein, (i) the MAAC Sponsor, any Affiliate of the MAAC Sponsor, any MAAC Independent Director or any
MAAC Independent Director Transferee (and, for the avoidance of doubt, any permitted transferees pursuant to this clause (i)) may transfer all or any of the Earn-Out Shares held by him, her or it in any
transfer of the type described in Sections 1(b)(iii)(A) through (C) or (F) of the applicable Lock-Up Agreement, provided that, in the case of a transfer of the type described in clauses
(A) through (C), the transferee shall, in addition to any requirements in the applicable Lock-Up Agreement, agree in writing that he, she or it is receiving and holding such
Earn-Out Shares subject to the provisions of this Section 2 and (ii) from and after a transfer pursuant to clause (i) of this sentence, all references to any of the MAAC
Sponsor, any Affiliate of the MAAC Sponsor, any MAAC Independent Director or any MAAC Independent Director Transferee in this Section 2 and Section 7 shall include such transferee and shall
collectively mean the MAAC Sponsor, any Affiliate of the MAAC Sponsor, any MAAC Independent Director or any MAAC Independent Director Transferee (to the extent that he, she or it then holds Earn-Out Shares)
and each permitted transferee of the Earn-Out Shares originally held by the MAAC Sponsor, any Affiliate of the MAAC Sponsor, any MAAC Independent Director or any MAAC Independent Director Transferee pursuant
to clause (i) of this sentence (in each case, to the extent he, she or it then holds Earn-Out Shares). Each transferee of Earn-Out Shares pursuant to clause
(i) of the preceding sentence shall be a third party beneficiary of this Section 2 and Section 7. 

(e) As used herein, “Stock Price” means, on any date on or after the Closing and on or prior to the Earn-Out End Date, the closing sale price per share of Company Post-Closing Common Shares reported as of 4:00 p.m., New York, New York time on such date by Bloomberg, or if not available on Bloomberg, as reported by
or an authoritative source generally used for such purposes and selected by the Company, and “Trading Day” means any day on which trading is generally conducted on Nasdaq or any other exchange on which the Company Post-Closing
Common Shares are traded on or after the Closing and on or prior to the Earn-Out End Date. The Earn-out Shares and the applicable Trigger Price (and all references to
Company Post-Closing Common Shares and each of the foregoing in this Agreement) shall each be adjusted appropriately to reflect the effect of any stock split, reverse stock split, stock dividend (including any dividend or other distribution of
securities convertible into Company Post-Closing Common Shares), reorganization, recapitalization, reclassification, combination, exchange of shares or other like change with respect to the Company Post-Closing Common Shares (or any other Equity
Securities into which they are adjusted pursuant to this Section 2(e)) at any time prior to the vesting of the Earn-out Shares pursuant to this Section 2 so
as to provide the holders of the Earn-Out Shares with the same economic effect as contemplated by this Section 2 prior to such event and as so adjusted shall, from and after the date
of such event, be the Earn-Out Shares and the 20% Trigger Price or the 10% Trigger Price, as applicable. 

(f) The Company shall use reasonable best efforts to remain listed as a public company on, and for the
Earn-Out Shares to be tradable over, Nasdaq or any other nationally recognized U.S. stock exchange; provided, however, the foregoing shall not limit the Company or any of its Affiliates from
consummating a Sale or entering into a definitive agreement that contemplates a Sale. Subject to Section 2(c) and the other applicable provisions of this Section 2, upon the consummation of Sale
the Company shall have no further obligations under this Section 2(f). 

  
 3 

 (g) At the time that the Earn-Out Shares become
vested pursuant to this Section 2, the Company shall remove any legends, stock transfer restrictions, stop transfer orders or similar restrictions with respect to the Earn-Out Shares
related to such vesting or this Section 2 (other than, for the avoidance of doubt, those that relate to any applicable and then-existing Lock-Up Period (as defined in the applicable Lock-Up Agreement) with respect to such Earn-Out Shares). 
 (h)
For the avoidance of doubt, (i) the MAAC Sponsor, any Affiliate of the MAAC Sponsor, any MAAC Independent Director or any MAAC Independent Director Transferee shall retain all of his, her or its rights as a stockholder of the Company with
respect to the Earn-Out Shares owned by him, her or it during any period of time that such shares are subject to restriction on transfer or sale hereunder, including the right to vote any such shares and the
right to receive dividends and other distributions with respect to such Earn-Out Shares prior to vesting (provided that dividends and other distributions with respect to
Earn-Out Shares that are subject to vesting and are unvested at the time of such dividend or distribution shall be set aside by the Company and shall only be paid to such holders upon the vesting of such Earn-Out Shares (and, if any dividends or other distributions with respect to Earn-Out Shares are set aside and such Earn-Out Shares
are subsequently forfeited pursuant to this Section 2, such set aside dividends or distributions shall become the property of the Company)), (ii) any Earn-Out Shares that vest in
accordance with the terms of this Section 2 shall remain subject to any applicable Lock-Up Period set forth in the applicable Lock-Up Agreement
and (iii) notwithstanding the expiration of any Lock-Up Period with respect to any Earn-Out Shares, such shares shall remain subject to any applicable restrictions
set forth this Section 2. 
 (i) The MAAC Sponsor, any Affiliate of the MAAC Sponsor, any MAAC Independent Director
or any MAAC Independent Director Transferee shall determine, based on advice from its own tax advisors, whether to make an election under Section 83(b) of the Code with respect to its Earn-Out Shares.

 (j) The Parties agree and acknowledge that the Earn-Out Shares are intended to constitute
“voting stock” within the meaning of Section 368(a)(1) of the Code and the Treasury Regulations promulgated thereunder received by of the MAAC Sponsor, any Affiliate of the MAAC Sponsor, any MAAC Independent Director or any MAAC
Independent Director Transferee in connection with the Merger, and shall file all Tax Returns consistent with, and take no position inconsistent with (whether in audits, Tax Returns or otherwise), such treatment unless (i) such Party requests
that each of Kirkland & Ellis LLP and Davis Polk & Wardwell LLP provides written confirmation to the effect that such treatment is more likely than not correct, and each such law firm fails to provide such confirmation prior to the
later of (A) thirty (30) days following such request is made and (B) sixty (60) days prior to the date on which the relevant Tax Return is due (taking into account applicable extensions); provided that the Parties shall provide
customary factual representations to such law firm; provided, further, that, for the avoidance of doubt, the Parties shall not be required to restructure, or otherwise alter the terms of, the transaction as provided for in this
Agreement or the Business Combination Agreement, or (ii) otherwise required by a final “determination” within the meaning of Section 1313(a) of the Code.” 

(k) The definition “Lock-Up Agreements” is hereby amended, and deemed, to include the MAAC
Independent Director Lock-Up Agreements.” 
 (b) Notwithstanding anything in the
Sponsor Support Agreement to the contrary, the Insiders acknowledge and agree that Section 2 of the Sponsor Support Agreement shall apply to the Insiders.

 ARTICLE II 

REGISTRATION RIGHTS 

Section 2.1 Form S-3 Demand Registration. 

(a) From and after a Listing Event, if at any time when it is eligible to use a Form S-3 registration
statement, the Company receives a request from any Holder (the “Initiating Holder”) that the Company file a Form S-3 registration statement with respect to outstanding Registrable Securities
of such Initiating Holder having an anticipated aggregate offering price, net of Selling Expenses, of at least [***], then the Company shall, (i) within [***] after the date such request is given, give notice of such demand (a “Demand
Notice”) to all Holders other than the Initiating Holder; and (ii) as soon as practicable, and in any event within [***] after the date such request is given by the Initiating Holder, file a Form
S-3 registration statement under the Securities Act covering all Registrable Securities requested to be included in such registration by the Initiating Holder and by any other Holder, as specified by notice
given by each such Holder to the Company within [***] of the date the Demand Notice is given, and in each case, subject to the limitations of Section 2.1(b) (Form S-3 Demand Registration) and
Section 2.3 (Underwriting Requirements). 
 (b) Notwithstanding the foregoing obligations, if the Company furnishes to the
Initiating Holder a certificate signed by any of the Company’s authorized officers stating that in the good faith judgment of the Board it would or would reasonably be expected to be materially detrimental to the Company and its stockholders
for such registration statement to either become effective or remain effective for as long as such registration statement otherwise would be required to remain effective, because such action would (i) materially interfere with a significant
acquisition, corporate reorganization, or other similar transaction involving the Company; (ii) require premature disclosure of material information that the Company has a bona fide business purpose for preserving as confidential; or
(iii) render the Company unable to comply with requirements under the Securities Act or Exchange Act, then the Company shall have the right to defer taking action with respect to such filing or suspend the use of such registration statement (a
“Suspension Period”); provided that the Company shall not be permitted to exercise a Suspension Period for more than a total of [***] consecutive calendar days or more than [***] total calendar days in any [***] period; and
provided further that the Company shall not register any securities for its own account or that of any other stockholder during any such Suspension Period other than an Excluded Registration. Each Holder agrees that, upon receipt of notice from the
Company of the occurrence of a Suspension Period, such Holder shall cease offering, selling or distributing the Registrable Securities owned by such Holder until the Company notifies such Holder that such Suspension Period has ended. 

(c) The Company shall not be obligated to effect, or to take any action to effect, any registration pursuant to Section 2.1(a) (Form S-3 Demand Registration): (i) during the period that is [***] before the Company’s good faith estimate of the date of filing of, and ending on a date that is [***] after the effective date of, a
Company-initiated registration, provided that the Company is actively employing in good faith commercially reasonable efforts to cause such registration statement to become effective; or (ii) if the Company has effected [***]
registrations pursuant to Section 2.1(a) (Form S-3 Demand Registration) within the [***] period immediately preceding the date of such request. A registration shall not be counted as
“effected” for purposes of this Section 2.1(c) (Form S-3 Demand Registration) until such time as the applicable registration statement has been declared effective by the SEC, unless the
Initiating Holder withdraws its request for such registration, elects not to pay the registration expenses therefor, and forfeits its right to one demand registration statement pursuant to Section 2.6 (Expenses of Registration), in which
case such withdrawn registration statement shall be counted as “effected” for purposes of this Section 2.1(c) (Form S-3 Demand Registration); provided, that if such withdrawal is
during a period the Company has deferred taking action pursuant to Section 2.1(b) (Form S-3 Demand Registration), then the Initiating Holders may withdraw their request for registration and such
registration will not be counted as “effected” for purposes of this Section 2.1(c) (Form S-3 Demand Registration). 

  
 7 

 Section 2.2 Company Registration. If the Company proposes
to register (including, for this purpose, a registration effected by the Company for stockholders other than the Holders) any of its Shares or other Equity Securities under the Securities Act in connection with the public offering of such securities
solely for cash (other than in an Excluded Registration), the Company shall, at such time, promptly give each Holder notice of such registration, which notice shall describe the amount and type of securities to be included in such offer, the
proposed manner of distribution and the name of the managing underwriter (if any and if known at such time). Upon the request of each Holder given within [***] after such notice is given by the Company, the Company shall, subject to the provisions
of Section 2.3 (Underwriting Requirements) cause to be registered all of the Registrable Securities that each such Holder has requested to be included in such registration. The Company shall have the right to terminate or withdraw any
registration initiated by it under this Section 2.2 (Company Registration), before the effective date of such registration, whether or not any Holder has elected to include Registrable Securities in such registration. The expenses (other
than Selling Expenses) of such withdrawn registration shall be borne by the Company in accordance with Section 2.6 (Expenses of Registration). 

Section 2.3 Underwriting Requirements. 

(a) If, pursuant to Section 2.1 (Form S-3 Demand Registration), the Initiating Holder
intends to distribute the Registrable Securities covered by its request by means of an underwriting, it shall so advise the Company as a part of their request made pursuant to Section 2.1 (Form S-3
Demand Registration), and the Company shall include such information in the Demand Notice. The underwriter(s) will be selected by the Company and shall be reasonably acceptable to the Initiating Holder. In such event, the right of any Holder to
include such Holder’s Registrable Securities in such registration shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting to the extent
provided herein. All Holders proposing to distribute their securities through such underwriting shall (together with the Company as provided in Section 2.4(e) (Obligations of the Company)) enter into an underwriting agreement in
customary form with the underwriter(s) selected for such underwriting; [***]. Notwithstanding any other provision of this Section 2.3 (Underwriting Requirements), if the managing underwriter(s) advise(s) the Initiating Holder in writing
that marketing factors require a limitation on the number of shares to be underwritten, then the Initiating Holder shall so advise all Holders of Registrable Securities that otherwise would be underwritten pursuant hereto, and the number of
Registrable Securities that may be included in the underwriting shall be allocated among such Holders of Registrable Securities, including the Initiating Holder, in proportion (as nearly as practicable) to the number of Registrable Securities owned
by each Holder or in such other proportion as shall mutually be agreed to by all such selling Holders; provided that the number of Registrable Securities held by the Holders to be included in such underwriting shall not be reduced unless all
other securities (held by non-Holders) are first entirely excluded from the underwriting. To facilitate the allocation of shares in accordance with the above provisions, the Company or the underwriters may
round the number of shares allocated to any Holder to the nearest one hundred (100) shares. 
 (b) In connection with any offering
involving an underwriting of Shares or other Equity Securities pursuant to Section 2.2 (Company Registration), the Company shall not be required to include any of the Holders’ Registrable Securities in such underwriting unless the
Holders accept the terms of the underwriting as agreed upon between the Company and its underwriters, and then only in such quantity as the underwriters in their sole discretion determine will not jeopardize the success of the offering by the
Company. If the total number of securities, including Registrable Securities, requested by stockholders to be included in such offering exceeds the number of securities to be sold (other than by the Company) that the underwriters in their sole
discretion determine is compatible with the success of the 

  
 8 

 
offering, then the Company shall be required to include in the offering only that number of such securities, including Registrable Securities, which the underwriters and the Company in their sole
discretion determine will not jeopardize the success of the offering. If the underwriters determine that less than all of the Registrable Securities requested to be registered can be included in such offering, then the Registrable Securities that
are included in such offering shall be allocated among the selling Holders in proportion (as nearly as practicable to) the number of Registrable Securities owned by each selling Holder or in such other proportions as shall mutually be agreed to by
all such selling Holders. To facilitate the allocation of shares in accordance with the above provisions, the Company or the underwriters may round the number of shares allocated to any Holder to the nearest one hundred (100) shares.
Notwithstanding the foregoing, in no event shall (i) the number of Registrable Securities included in the offering be reduced unless all other securities (other than securities to be sold by the Company) are first entirely excluded from the
offering, or (ii) the number of Registrable Securities included in the offering be reduced below [***] of the total number of securities included in such offering, unless such offering is a Qualified Listing Event, in which case the selling
Holders may be excluded further if the Company (and, if applicable, the underwriters) makes the determination described above and no other securities of the Company held by others are included in such offering. For purposes of the provision in this
Section 2.3(b) (Underwriting Requirements) concerning apportionment, for any selling Holder that is a partnership, limited liability company, or corporation, the partners, members, retired partners, retired members, stockholders, and
Affiliates of such Holder, or the estates and Immediate Family Members of any such partners, retired partners, members, and retired members and any trusts for the benefit of any of the foregoing Persons, shall be deemed to be a single “selling
Holder,” and any pro rata reduction with respect to such “selling Holder” shall be based upon the aggregate number of Registrable Securities owned by all Persons included in such “selling Holder,” as defined in this
sentence. 
 (c) For purposes of Section 2.1 (Form S-3 Demand Registration), a
registration shall not be counted as “effected” if, as a result of an exercise of the underwriter’s cutback provisions in Section 2.3(a) (Underwriting Requirements), fewer than [***] of the total number of Registrable
Securities that Holders have requested to be included in such registration statement are actually included. 

Section 2.4 Obligations of the Company. Whenever required under this Article II (Registration Rights) to
effect the registration of any Registrable Securities, the Company shall, as expeditiously as reasonably possible: 
 (a) prepare and file
with the SEC a registration statement with respect to such Registrable Securities and use commercially reasonable efforts to cause such registration statement to become effective and, upon the request of any Holder, keep such registration statement
effective for a period of up to [***] or, if earlier, until the distribution contemplated in the registration statement has been completed; provided that: (i) such [***] period shall be extended for a period of time equal to the period
the Holder refrains, at the request of an underwriter of Shares or other Equity Securities, as applicable, from selling any securities included in such registration, and (ii) in the case of any registration of Registrable Securities on Form S-3 that are intended to be offered on a continuous or delayed basis, subject to compliance with applicable SEC rules, such [***] period shall be extended for up to [***], if necessary, to keep the registration
statement effective until all such Registrable Securities are sold; 
 (b) prepare and file with the SEC such amendments and supplements to
such registration statement, and the prospectus used in connection with such registration statement, as may be necessary to comply with the Securities Act in order to enable the disposition of all securities covered by such registration statement
and provide the selling Holders and their counsel a reasonable opportunity to review and comment on such amendments and supplements prior to filing them with the SEC; 

  
 9 

 (c) furnish to the selling Holders such numbers of copies of a prospectus, including a
preliminary prospectus, as required by the Securities Act, and such other documents as such Holders may reasonably request in order to facilitate the disposition of their Registrable Securities and provide such Holders and their counsel a reasonable
opportunity to review and comment on such prospectus prior to filing it with the SEC; 
 (d) use its commercially reasonable efforts to
register and qualify the securities covered by such registration statement under such other securities or blue-sky laws of such jurisdictions as shall be reasonably requested by the selling Holders;
provided that the Company shall not be required to qualify to do business or to file a general consent to service of process in any such states or jurisdictions, unless the Company is already subject to service in such jurisdiction and except
as may be required by the Securities Act; 
 (e) in the event of any underwritten public offering, enter into and perform its obligations
under an underwriting agreement, in usual and customary form, with the underwriter(s) of such offering; 
 (f) use its commercially
reasonable efforts to cause all such Registrable Securities covered by such registration statement to be listed on a national securities exchange or trading system and each securities exchange and trading system (if any) on which similar securities
issued by the Company are then listed; 
 (g) provide a transfer agent and registrar for all Registrable Securities registered pursuant to
this Agreement and provide a CUSIP number for all such Registrable Securities, in each case not later than the effective date of such registration; 

(h) notify each selling Holder of such Registrable Securities, at any time when a prospectus or Free Writing Prospectus relating thereto 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 an untrue statement of a material fact or omits to state any
material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading (which, for the avoidance of doubt, will commence a Suspension Period) and, at
the request of any such Holder, the Company will, as soon as reasonably practicable, file and furnish to all such Holders a supplement or amendment to such prospectus or Free Writing Prospectus so that, as thereafter delivered to the purchasers of
such Registrable Securities, such prospectus will not contain an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein not misleading in light of the circumstances under which they were made;

 (i) promptly make available for inspection by the selling Holders, any managing underwriter(s) participating in any disposition pursuant
to such registration statement, and any attorney or accountant or other agent retained by any such underwriter or selected by the selling Holders, all financial and other records, pertinent corporate documents, and properties of the Company, and
cause the Company’s officers, directors, employees, and independent accountants to supply all information reasonably requested by any such seller, underwriter, attorney, accountant, or agent, in each case, as necessary or advisable to verify
the accuracy of the information in such registration statement and to conduct appropriate due diligence in connection therewith; 
 (j) use
its commercially reasonable efforts to furnish, at the request of any selling Holder requesting registration of Registrable Securities pursuant to this Article II, if such securities are being sold through underwriters, (i) an opinion, dated
such date, of the counsel representing the Company for the purposes of such registration, in form and substance as is customarily given to underwriters in an 

  
 10 

 
underwritten public offering, addressed to the underwriters, (ii) a “negative assurances letter”, dated such date, of the legal counsel representing the Company for the purposes of
such registration, in form and substance as is customarily given to underwriters in an underwritten public offering and (iii) a letter dated such date, from the independent certified public accountants of the Company, in form and substance as
is customarily given by independent certified public accountants to underwriters in an underwritten public offering, addressed to the underwriters; 

(k) in connection with an underwritten offering, the Company shall cause its officers to use their commercially reasonable efforts to support
the marketing of the Registrable Securities covered by such offering (including participation in “road shows” or other similar marketing efforts); 

(l) cooperate with the selling Holder and each underwriter or agent participating in the disposition of Registrable Securities and their
respective counsel in connection with any filings required to be made with FINRA, including the use of commercially reasonable efforts to obtain FINRA’s pre-clearance or
pre-approval of the registration statement and applicable prospectus upon filing with the SEC; 

(m) notify each selling Holder, promptly after the Company receives notice thereof, of the time when such registration statement has been
declared effective or a supplement to any prospectus forming a part of such registration statement has been filed; and 
 (n) after such
registration statement becomes effective, notify each selling Holder of any request by the SEC that the Company amend or supplement such registration statement or prospectus. 

In addition, the Company shall ensure that, at all times after any registration statement covering a public offering of securities of the
Company under the Securities Act shall have become effective, its insider trading policy shall provide that the Company’s directors may implement a trading program under Rule 10b5-1 of the Exchange Act.

 Section 2.5 Furnish Information. It shall be a condition precedent to the obligations of the Company to take
any action pursuant to this Article II (Registration Rights) with respect to the Registrable Securities of any selling Holder that such Holder shall furnish to the Company such information regarding itself, the Registrable Securities held by
it, and the intended method of disposition of such securities as is reasonably required to effect the registration of such Holder’s Registrable Securities. 

Section 2.6 Expenses of Registration. All expenses (other than Selling Expenses) incurred in connection with
registrations, filings, or qualifications pursuant to Article II (Registration Rights), including all registration, filing, and qualification fees; printers’ and accounting fees; fees and disbursements of counsel for the Company; [***],
shall be borne and paid by the Company; provided that the Company shall not be required to pay for any expenses of any registration proceeding begun pursuant to Section 2.1 (Form S-3 Demand
Registration), if the registration request is subsequently withdrawn at the request of the Holders of a majority of the Registrable Securities to be registered (in which case all selling Holders shall bear such expenses pro rata based upon the
number of Registrable Securities that were to be included in the withdrawn registration), unless the Holders of a majority of the Registrable Securities agree to forfeit their right to one registration pursuant to Section 2.1(a) (Form S-3 Demand Registration); provided further that if, at the time of such withdrawal, (i) the Holders shall have learned of a material adverse change in the condition, business, or prospects of the Company
from that known to the Holders at the time of their request and have withdrawn the request with reasonable promptness after learning of such material adverse change or (ii) if the Holders have withdrawn the request in connection with the
deferral of a registration by the Company pursuant to Section 2.1(b) (Form S-3 Demand Registration), then the Holders shall not be required to pay any of such expenses and shall not forfeit their
right to one registration pursuant to Section 2.1(a) (Form S-3 Demand Registration). All Selling Expenses relating to Registrable Securities registered pursuant to this Article II (Registration
Rights) [***] shall be borne and paid by the Holders pro rata on the basis of the number of Registrable Securities registered on their behalf.

to obtain or seek an injunction restraining or otherwise delaying any registration pursuant to this Agreement as the result of any controversy that might arise with respect to the interpretation or implementation of this Article II (Registration
Rights). 
 Section 2.8 Indemnification. If any Registrable Securities are included in a registration
statement under this Article II (Registration Rights): 
 (a) To the extent permitted by applicable Law or Order, the Company will
indemnify and hold harmless each selling Holder, and the partners, members, officers, directors, and stockholders of each such Holder; legal counsel and accountants for each such Holder; any underwriter (as defined in the Securities Act) for each
such Holder; and each Person, if any, who controls such Holder or underwriter within the meaning of the Securities Act or the Exchange Act, against any Damages, and the Company will pay to each such Holder, underwriter, controlling Person, or other
aforementioned Person any legal or other expenses reasonably incurred thereby in connection with investigating or defending any claim or proceeding from which Damages may result, as such expenses are incurred; provided that the indemnity
agreement contained in this Section 2.8(a) (Indemnification) shall not apply to amounts paid in settlement of any such claim or proceeding if such settlement is effected without the consent of the Company, which consent shall not be
unreasonably withheld, nor shall the Company be liable for any Damages to the extent that they arise out of or are based upon actions or omissions made in reliance upon and in conformity with written information furnished by or on behalf of any such
Holder, underwriter, controlling Person, or other aforementioned Person expressly for use in connection with such registration. 
 (b) To
the extent permitted by applicable Law or Order, each selling Holder, severally and not jointly, will indemnify and hold harmless the Company, and each of its directors, each of its officers who has signed the registration statement, each Person (if
any), who controls the Company within the meaning of the Securities Act, legal counsel and accountants for the Company, any underwriter (as defined in the Securities Act), any other Holder selling securities in such registration statement, and any
controlling Person of any such underwriter or other Holder, against any Damages, in each case only to the extent that such Damages arise out of or are based upon actions or omissions made in reliance upon and in conformity with written information
furnished by or on behalf of such selling Holder expressly for use in connection with such registration; and each such selling Holder will pay to the Company and each other aforementioned Person any legal or other expenses reasonably incurred
thereby in connection with investigating or defending any claim or proceeding from which Damages may result, as such expenses are incurred; provided that the indemnity agreement contained in this Section 2.8(b) (Indemnification)
shall not apply to amounts paid in settlement of any such claim or proceeding if such settlement is effected without the consent of the Holder, which consent shall not be unreasonably withheld; and provided further that in no event shall the
aggregate amounts payable by any Holder by way of indemnity or contribution under Section 2.8(b) (Indemnification) and Section 2.8(d) (Indemnification) exceed the proceeds from the offering received by such Holder (net of any
Selling Expenses paid by such Holder), except in the case of fraud or willful misconduct by such Holder. 
 (c) Promptly after receipt by an
indemnified party under this Section 2.8 (Indemnification) of notice of the commencement of any action (including any governmental action) for which a party may be entitled to indemnification hereunder, such indemnified party will, if a
claim in respect thereof is to be made against any indemnifying party under this Section 2.8 (Indemnification), give the indemnifying party notice of the commencement thereof. The indemnifying party shall have the right to participate in
such action and, to the extent the indemnifying party so desires, participate jointly with any 

  
 12 

 
other indemnifying party to which notice has been given, and to assume the defense thereof with counsel mutually satisfactory to the Parties; provided that an indemnified party (together
with all other indemnified parties that may be represented without conflict by one counsel) shall have the right to retain one separate counsel, with the fees and expenses to be paid by the indemnifying party, if representation of such indemnified
party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential differing interests between such indemnified party and any other party represented by such counsel in such action. The failure to give notice
to the indemnifying party within a reasonable time of the commencement of any such action shall relieve such indemnifying party of any liability to the indemnified party under this Section 2.8 (Indemnification), to the extent that such
failure materially prejudices the indemnifying party’s ability to defend such action. The failure to give notice to the indemnifying party will not relieve it of any liability that it may have to any indemnified party otherwise than under this
Section 2.8 (Indemnification). 
 (d) To provide for just and equitable contribution to joint liability under the Securities Act
in any case in which either: (i) any party otherwise entitled to indemnification hereunder makes a claim for indemnification pursuant to this Section 2.8 (Indemnification) but it is judicially determined (by the entry of a final
judgment or decree by a court of competent jurisdiction and the expiration of time to appeal or the denial of the last right of appeal) that such indemnification may not be enforced in such case, notwithstanding the fact that this Section 2.8
(Indemnification) provides for indemnification in such case, or (ii) contribution under the Securities Act may be required on the part of any Party hereto for which indemnification is provided under this Section 2.8
(Indemnification), then, and in each such case, such Parties will contribute to the aggregate losses, claims, damages, liabilities, or expenses to which they may be subject (after contribution from others) in such proportion as is appropriate
to reflect the relative fault of each of the indemnifying party and the indemnified party in connection with the statements, omissions, or other actions that resulted in such loss, claim, damage, liability, or expense, as well as to reflect any
other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether the untrue or allegedly untrue statement of a material fact, or the
omission or alleged omission of a material fact, relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access to information, and opportunity to correct or prevent
such statement or omission; provided that, in any such case (x) no Holder will be required to contribute any amount in excess of the public offering price of all such Registrable Securities offered and sold by such Holder pursuant to
such registration statement (net of any Selling Expenses paid by such Holder), and (y) no Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any
Person who was not guilty of such fraudulent misrepresentation; and provided further that in no event shall a Holder’s liability pursuant to this Section 2.8(d) (Indemnification), when combined with the amounts paid or payable by

written statement by the Company that it has complied with the reporting requirements of SEC Rule 144 (at any time after 90 days after the applicable Listing Event), the Securities Act, and the Exchange Act (at any time after the Company has become
subject to such reporting requirements), or that it qualifies as a registrant whose securities may be resold pursuant to Form S-3 (at any time after the Company so qualifies) and (ii) such other
information as may be reasonably requested in availing any Holder of any rule or regulation of the SEC that permits the selling of any such securities without registration (at any time after the Company has become subject to the reporting
requirements under the Exchange Act) or pursuant to Form S-3 (at any time after the Company so qualifies to use such form). 

Section 2.10 Limitations on Subsequent Registration Rights. From and after the date of this Agreement, the Company
shall not, without the prior written consent of the Holders, enter into any agreement with any holder or prospective holder of any securities of the Company that: (a) would provide to such holder the right to include securities in any
registration on other than either (i) a pro rata basis with respect to the Registrable Securities or (ii) on a subordinate basis after all of the Holders have had the opportunity to include in the registration and offering all Registrable
Securities that they wish to so include or (b) allow such holder or prospective holder to initiate a demand for registration of any securities held by such holder or prospective holder. 

Section 2.11 “Market Stand-off”
Agreement. Each Holder agrees that it will not, without the prior written consent of the Company and, if applicable, the managing underwriter, during the Standoff Period: (a) lend; offer; pledge; sell; contract to sell; sell any option or
contract to purchase; purchase any option or contract to sell; grant any option, right, or warrant to purchase; or otherwise Transfer or dispose of, directly or indirectly, any Shares or any securities convertible into or exercisable or exchangeable
(directly or indirectly) for Shares or (b) enter into any swap or other arrangement that Transfers to another, in whole or in part, any of the economic consequences of ownership of such securities, whether any such transaction described in
clause (a) or (b) above is to be settled by delivery of Shares or other securities, in cash, or otherwise. The foregoing provisions of this Section 2.11 (“Market
Stand-off” Agreement) shall not apply to the sale of any shares to an underwriter pursuant to an underwriting agreement or the Transfer of any shares to any Designated Affiliate of the
Holder; provided that such Designated Affiliate shall agree to be bound by the provisions of this Section 2.11 (“Market Stand-off” Agreement) with
respect to future Transfers; provided further that this Section 2.11 (“Market Stand-off” Agreement) shall be applicable to each Holder and transferee only if

connection with a Qualified Listing Event and (y) in respect of a non-QLE Standoff Period, the Company entering into an underwriting agreement in
respect of the applicable underwritten public offering, are subject to the same restrictions and the Company obtains a substantially identical agreement from all other Investors. Any discretionary waiver or termination of the restrictions of any or
all of such agreements by the Company or the underwriters shall apply pro rata to all Company stockholders that are subject to such agreements, based on the number of shares subject to such agreements. The underwriters, if any, in connection with
such Qualified Listing Event or other underwritten public offering of the Company’s Equity Securities under the Securities Act are intended third party beneficiaries of this Section 2.11 (“Market
Stand-off” Agreement) and shall have the right, power, and authority to enforce the provisions hereof as though they were a party hereto. Each Holder further agrees to execute such agreements as may
be reasonably requested by the Company or the underwriters in connection with such registration or other transaction that are consistent with this Section 2.11 (“Market Stand-off”
Agreement) or that are necessary to give further effect thereto. In order to enforce the foregoing covenant, the Company may impose stop-transfer instructions with respect to the Registrable Securities (and the Equity Securities of every other
Person subject to the foregoing restriction) until the end of such restricted period. 
 Section 2.12
Restrictions on Transfer. 
 (a) The Preferred Stock and the Registrable Securities shall not be Transferred, and the Company
shall not recognize and shall issue stop-transfer instructions to its transfer agent with respect to any such Transfer, except upon the conditions specified in this Agreement, which conditions are intended to ensure compliance with the provisions of
the Securities Act. Each Holder, if effecting a Transfer, will cause any proposed transferee of the Preferred Stock and the Registrable Securities to agree to take and hold such securities subject to the provisions and upon the conditions specified
in this Agreement. 
 (b) Each certificate or instrument representing the Preferred Stock, the Registrable Securities, and any other
securities issued in respect of such Preferred Stock or Registrable Securities, upon any split, dividend, recapitalization, merger, amalgamation, consolidation, or similar event, shall (unless otherwise permitted by the provisions of
Section 2.12(c) (Restrictions on Transfer) be stamped or otherwise imprinted with a legend substantially in the following form: 

THE SECURITIES REPRESENTED BY THIS CERTIFICATE WERE ORIGINALLY ISSUED ON __________ ____, 20__, HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR APPLICABLE STATE SECURITIES LAWS (“STATE ACTS”) AND MAY NOT BE TRANSFERRED, SOLD, ASSIGNED, PLEDGED, HYPOTHECATED OR OTHERWISE DISPOSED OF (“TRANSFERRED”) IN THE
ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR STATE ACTS OR AN EXEMPTION FROM REGISTRATION THEREUNDER. 
 THE
SECURITIES REPRESENTED BY THIS CERTIFICATE MAY NOT BE TRANSFERRED EXCEPT IN ACCORDANCE WITH THE PROVISIONS OF THE BYLAWS OF THE COMPANY, A CERTAIN INVESTOR RIGHTS AGREEMENT BY AND AMONG THE COMPANY AND CERTAIN STOCKHOLDERS OF THE COMPANY AND A
CERTAIN RIGHT OF FIRST REFUSAL AND CO-SALE AGREEMENT BY AND AMONG THE COMPANY AND CERTAIN STOCKHOLDERS OF THE COMPANY. ANY TRANSFEREE OF THESE SECURITIES TAKES SUBJECT TO THE TERMS THEREOF.

 The Holders consent to the Company’s making a notation in its records and giving
instructions to any transfer agent of the Restricted Securities in order to implement the restrictions on Transfer set forth in this Section 2.12 (Restrictions on Transfer). 

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

(d) Notwithstanding the provisions of Sections Section 2.12(a) (Restrictions on Transfer) and 2.12(c) (Restrictions on
Transfer) above, no such registration statement or opinion of counsel or “no action” letter shall be necessary for: (a) a transfer by a Holder to any of its Affiliates, (b) a transfer by a Holder that is a partnership,
limited liability company or corporation to a partner, limited partner, retired partner, member, retired member or stockholder of a Holder; (c) a transfer to a Charity; (d) a transfer by gift, will or intestate succession of any partner to
his or her spouse or to the siblings, lineal descendants or ancestors of such partner or his or her spouse; or (e) the transfer by a Holder exercising its co-sale rights under the Right of First Refusal
and Co-Sale Agreement by and among the Company and the Investors and Common Holders named therein of even date herewith, as amended, if in each transfer under clauses (a), (b), (c) or (d) the prospective
transferee agrees in all such instances in writing to be subject to the terms hereof to the same extent as if he or she were an original Holder hereunder. 

(e) The rights to cause the Company to register Registrable Securities pursuant to this Section 2.12(e) (Restrictions on Transfer)
may be assigned by a Holder to a transferee or assignee of Registrable Securities (for so long as such shares remain Registrable Securities) that (a) is a subsidiary, parent, general partner, limited partner, retired partner, member or retired
member, of a Holder that is a corporation, partnership or limited liability company, (b) is a Holder’s family member or trust for the benefit of an individual Holder, (c) acquires at least [***] of the then-outstanding Registrable
Securities or (d) is an Affiliate of such Holder; provided, however, that (i) the transferor shall, within [***] after such transfer, furnish to the Company written notice of the name and address of such transferee or assignee and the
securities with respect to which such registration rights are being assigned and (ii) such transferee shall agree to be subject to all restrictions set forth in this Agreement. 

  
 16 

 Section 2.13 Termination of Registration Rights. The right
of any Holder to request registration or inclusion of Registrable Securities in any registration pursuant to Section 2.1 (Form S-3 Demand Registration) or Section 2.2 (Company
Registration) shall terminate upon the earliest to occur of: 
 (a) the consummation of a Change of Control of the Company or the
liquidation, winding up or other dissolution of the Company; 
 (b) such time as Rule 144 or another similar exemption under the Securities
Act is available for the sale of all of such Holder’s shares without limitation during a three-month period without registration; and

Section 3.4 (Confidentiality) by such Investor), (b) is or has been independently developed or conceived by such Investor without use of the Company’s information or (c) is or has been made known or disclosed to such Investor
by a third party without a known or reasonably expected breach of any obligation of confidentiality such third party may have to the Company; provided, however, that an Investor may disclose confidential information: (i) to its attorneys,

anyone to whom it discloses information receives a request, or is legally required, to disclose all or any part of the information under the terms of a subpoena or other Order, provided that the Investor shall (a) promptly notify the

 ARTICLE IV 

RIGHT TO FUTURE SHARE ISSUANCES 

Section 4.1 Right of First Offer. Subject to the terms and conditions of this Section 4.1 (Right of
First Offer) and applicable Laws and Orders, if the Company proposes to offer or sell any New Securities, the Company shall first offer such New Securities to each Investor. An Investor shall be entitled to apportion the right of first offer
hereby granted to it in such proportions as it deems appropriate, among (i) itself and (ii) its Affiliates; provided that each such Affiliate agrees to enter into this Agreement and the Voting Agreement of even date herewith among
the Company, the Investors and the other parties named therein, as an “Investor” in each such agreement. 
 (a) The Company
shall give notice (the “Offer Notice”) to each Investor, stating (i) its bona fide intention to offer such New Securities, (ii) the number of such New Securities to be offered, and (iii) the price and terms, if any,
upon which it proposes to offer such New Securities. 
 (b) By notification to the Company within [***] after the Offer Notice is given,
each Investor may irrevocably elect to purchase or otherwise acquire, at the price and on the terms specified in the Offer Notice, up to that portion of such New Securities which equals the proportion that the Equity Securities then Beneficially
Owned by such Investor and its Designated Affiliates (including all Equity Securities then issuable (directly or indirectly) upon conversion or exercise, as applicable, of any other Equity Securities then held by such Investor) bears to the total
Equity Securities of the Company then outstanding (assuming full conversion or exercise, as applicable, of all other Equity Securities then outstanding) (with respect to each Investor, the “Proportionate Percentage”); provided,
however, that an Investor’s election to purchase or acquire New Securities may be revoked in the event (i) any of the terms set forth in the Offer Notice are changed or (ii) any material term that had not been set forth in the Offer
Notice is required or included in connection with such Investor’s purchase or acquisition of such New Securities. The closing of any sale pursuant to this Section 4.1(b) (Right of First Offer) shall occur within the later of [***]
of the date that the Offer Notice is given and the date of initial sale of New Securities pursuant to Section 4.1(c) (Right of First Offer); provided, however, that if such sale pursuant to this Section 4.1(b) would require the
approval of any Governmental Authority prior to consummating such sale, such closing shall be extended to the date that is [***] after such approval has been obtained or finally denied, but in no event later than [***] after the Offer Notice is
given. 
 (c) If all New Securities referred to in the Offer Notice are not elected to be purchased or acquired as provided in
Section 4.1(b) (Right of First Offer), the Company may, during the [***] period following the expiration of the periods provided in Section 4.1(b) (Right of First Offer), offer and sell the remaining unsubscribed portion of
such New Securities to any Person or Persons at a price not less than, and upon terms not materially more favorable in the aggregate to the offeree than, those specified in the Offer Notice. If the Company does not enter into an agreement for the
sale of the New Securities within such period, the right provided hereunder shall be deemed to be revived and such New Securities shall not be offered unless first reoffered to the Investors in accordance with this Section 4.1 (Right of
First Offer). 

  
 19 

 (d) The right of first offer in this Section 4.1 (Right of First Offer) shall
not be applicable to issuances of: (i) Exempted Securities; and (ii) securities issued in a Qualified Listing Event or to a new holding company solely for the purposes of a forthcoming Qualified Listing Event. In addition to the foregoing,
the right of first offer in this Section 4.1 (Right of First Offer) shall not be applicable with respect to any particular Investor in any subsequent offering or sale of New Securities if (x) at the time of such offering or sale,
such Investor is neither a “qualified institutional buyer” as that term is defined in Rule 144A under the Securities Actor nor an “accredited investor” as that term is defined in Rule 501(a) of the Securities Act and
(y) such offering or sale of Shares is otherwise being offered or made only to qualified institutional buyers or accredited investors, as the case may be. 

(e) Notwithstanding anything to the contrary contained herein, in lieu of complying with the provisions of this Section 4.1 (Right of
First Offer), the Company may consummate the offering and sale of New Securities without first providing an Offer Notice pursuant to Section 4.1(b) (Right of First Offer), provided that the Company complies with the terms and
conditions of this Section 4.1(e) (Right of First Offer). In the event that an offering or sale of New Securities is consummated without prior delivery of an Offer Notice to one or more Investors, the Company shall, within
[***] from the closing of such offer and sale of New Securities, provide each non-participating Investor with written notice of such offering (including the material terms and conditions thereof) and thereupon
provide each such Investor with the right, which shall be exercisable for a period of [***] from delivery of such notice, to subscribe for a number of New Securities equal to such Investor’s Proportionate Percentage (calculated pursuant to
Section 4.1(b) (Right of First Offer) before giving effect to the issuance of the New Securities) of the shares offered and sold in such offering, at the same price and on the same terms and conditions as which such securities were first
sold. The closing of such sale shall occur within [***] of the date the notice is given to the Investor. 

Section 4.2 Termination. The covenants set forth in Section 4.1 (Right of First Offer) shall terminate
and be of no further force or effect upon the earliest of: (i) immediately before the consummation of a Qualified Listing Event (ii) the consummation of a Change of Control of the Company or (iii) the liquidation, winding up or other
dissolution of the Company.

oral or otherwise, disclosing the existence of the Transaction Documents, the terms hereof or thereof or any information relating to the Transaction Documents without the prior written consent of the other Parties, such consent not to be
unreasonably withheld, conditioned or delayed; provided that a Party desiring to make such public disclosure may issue such press release or public announcement without such prior written consent by the other Party if (a) the entire
contents of such press release or public announcement have previously been made public other than through a breach of the Transaction Documents by such Party, and (b) such press release or public announcement does not materially differ from a
previously issued press release or other publicly available information. No Party will be prevented from complying with any duty of disclosure it may have pursuant to applicable Law or the rules of any recognized stock exchange so long as the

ARTICLE VI 

MISCELLANEOUS. 

Section 6.1 Successors and Assigns; Third Party Beneficiaries. No Investor shall assign its rights under this
Agreement without the Company’s prior written consent, except by a Holder to a transferee of Registrable Securities in accordance with this Agreement, or as otherwise expressly permitted by the terms hereof: (x) that is a Designated
Affiliate of such Holder or (y) in connection with the Transfer of all Registrable Securities held by such Holder to such transferee; provided that: (i) such Transfer or assignment may otherwise be effected in accordance with
applicable Laws and Orders, (ii) the Company is, within two (2) Business Days after such Transfer, furnished with written notice of the name and address of such transferee and the Registrable Securities with respect to which such rights
are being transferred; and (iii) such transferee agrees in a written instrument, in form and substance satisfactory to the Company, delivered to the Company to be bound by and subject to the terms and conditions of this Agreement, including the
provisions of Section 2.11 (“Market Stand-off” Agreement); and provided further that, for the avoidance of doubt, in no case shall any Investor assign its
rights under Section 5.1 (Protective Provisions) of this Agreement pursuant to the preceding clause (y) without the Company’s prior written consent. The terms and conditions of this Agreement inure to the benefit of and are
binding upon the respective successors and permitted assignees of the Parties. Nothing in this Agreement, express or implied, is intended to confer upon any Party other than the Parties hereto or their respective successors and permitted assignees
any rights, remedies, obligations or liabilities under or by reason of this Agreement, except as expressly provided herein. 

Section 6.2 Governing Law; Dispute Resolution. 

(a) This Agreement shall be governed and construed in all respects in accordance with the internal law of the State of Delaware, as such laws
are applied to agreements among Delaware residents entered into and performed entirely within the state of Delaware, without regard to conflict of law principles that would result in the application of any law other than the law of the State of
Delaware. 
 (b) The Parties shall negotiate in good faith and use reasonable efforts to settle any dispute, controversy or action arising
from or related to this Agreement or the breach thereof. In the event that the Parties cannot resolve such dispute, controversy or action within a period of [***] from when the dispute, controversy or action is first identified in writing by the
Party raising or asserting such dispute, controversy or action, then the matter shall be referred to designated representatives of the Parties for resolution by the sending of a notice of dispute(s) (a “Notice of Dispute(s)”). The
designated representatives shall endeavor to meet in person or by means of telephone conference, video conference or similar communications equipment by means of which all Persons participating in the meeting can hear and speak to each other, and
where such participation by the Parties’ designated representatives shall constitute presence in person at the meeting, within [***] following transmittal of the Notice of Dispute(s). Each Party shall be entitled to name representatives upon
written notice to the other Party. The foregoing duties may be delegated to the extent the person delegated with such duties is duly authorized to enter into the foregoing resolution without seeking any additional approval within the respective
Party. 
 (c) If the Parties do not fully settle any dispute, controversy or action referred to the representatives of the Parties within
[***] of it being referred to them, and a Party wishes to pursue the matter, then such dispute, controversy or action shall be finally resolved by binding arbitration administered by the American Arbitration Association (“AAA”)
pursuant to AAA’s Commercial Arbitration Rules then in effect. 

  
 23 

 (d) The arbitration shall be conducted by a panel of three (3) neutral arbitrators,
each of whom shall have significant legal or business experience in the pharmaceutical industry, and none of whom shall be a current or former employee or director, or a current significant shareholder, of either Party or any of their respective
Affiliates or sublicensees; and within [***] after initiation of arbitration, each Party shall select one (1) person to act as arbitrator and the two (2) Party-selected arbitrators shall select a third (3rd) arbitrator within [***] of
their appointment. If the arbitrators selected by the Parties are unable or fail to agree upon the third (3rd) arbitrator, then on the [***] after the initiation of arbitration, the two (2) Party-selected arbitrators shall make a written
request to AAA to appoint a third (3rd) arbitrator. AAA shall appoint such third (3rd) arbitrator within [***] of being notified by the two (2) Party-selected arbitrators. The place of arbitration shall be New York, New York, and all
proceedings and communications shall be in English. The award rendered by the arbitrators shall be final, binding and non-appealable, and judgment may be entered upon it in any court of competent jurisdiction.

 (e) Either Party may apply to the arbitrators for interim injunctive relief until the arbitration award is rendered or the controversy is
otherwise resolved. Either Party has the right to file an early dispositive motion seeking a determination on the issue of whether a material breach has occurred, and the arbitrators will promptly rule on such motion. Each Party shall bear its own
costs and expenses and attorneys’ fees and an equal share of the arbitrators’ fees and any administrative fees of arbitration. 

(f) Except to the extent necessary to confirm or enforce an award or as may be required by applicable Law, neither Party nor an arbitrator may
disclose the existence, content or results of an arbitration without the prior written consent of the other Party. In no event shall an arbitration be initiated after the date when commencement of a legal or equitable action based on the dispute,
controversy or action would be barred by the applicable statute of limitations in the state of Delaware. 

Section 6.3 Specific Performance. Each Party agrees that irreparable damage for which monetary relief, even
if available, would not be an adequate remedy, would occur in the event that any provision of this Agreement is not performed in accordance with its specific terms or is otherwise breached. Each Party acknowledges and agrees that, notwithstanding
Section 6.2 (Governing Law; Dispute Resolution), and without waiving any other remedy under this Agreement, the Parties shall be entitled to an injunction or injunctions, specific performance or other equitable relief from any court of
competent jurisdiction to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof. The Parties agree not to assert that a remedy of specific enforcement or other equitable relief is unenforceable, invalid,
contrary to Law or inequitable for any reason, and agree not to assert that a remedy of monetary damages would provide an adequate remedy or that the Parties otherwise have an adequate remedy at Law. The Parties acknowledge and agree that any Party
seeking an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in accordance with this Section 6.3 (Specific Performance) shall not be required to provide
any bond or other security in connection with any such injunction. 
 Section 6.4 Counterparts. This Agreement may
be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Counterparts may be delivered via facsimile, electronic mail (including pdf or any electronic
signature complying with the U.S. federal ESIGN Act of 2000, e.g., www.docusign.com) or other transmission method and any counterpart so delivered shall be deemed to have been duly and validly delivered and be valid and effective for all
purposes.

failure to object promptly in writing after notification of a proposed assignment allegedly in violation of Section 2.12(c) (Restrictions on Transfer) shall be deemed to be a waiver); and provided further that any provision hereof may be
waived by any waiving Party on such Party’s own behalf, without the consent of any other Party. Notwithstanding the foregoing:
