pursuant to applicable securities laws) or court of competent jurisdiction or requested by a Governmental Entity; provided, that (other than in the case of any required filing following the Closing Date with the SEC or in connection with any
Regulatory Inquiry, for which notification shall expressly not be required) such Party promptly notifies PubCo of such requirement or request and takes commercially reasonable steps, at the sole cost and expense of PubCo, to minimize the extent of
any such required disclosure, (c) such information was available or becomes available to such Party before, on or after the Effective Date, without restriction, from a source (other than PubCo) without any breach of duty to PubCo or any of its
Affiliates or (d) such information was independently developed by such Party or its Representatives without the use of, or reference to, the Confidential Information. Notwithstanding the foregoing, nothing in this Investor Rights Agreement
shall prohibit the Shareholder Representative and Sponsor from disclosing Confidential Information (x) to any Affiliate, Representative, limited partner, member, shareholder or other equity holder of such Party, provided, that such Person shall
be bound by an obligation of confidentiality with respect to such Confidential Information and such Party shall be responsible for any breach of this Section 2.4 by any such Person or (y) if such disclosure is made
pursuant to any examinations, audits, investigations, regulatory sweeps or other regulatory inquiries by regulatory agencies, self-regulatory organizations, governmental agencies or examiners thereof (each a “Regulatory
Inquiry”) with jurisdiction over such Party in connection with a Regulatory Inquiry that is not specifically directed at PubCo or the Confidential Information, provided that such Party shall request that confidential treatment be
accorded to any information so disclosed. No Confidential Information shall be deemed to be provided to any Person, including any Affiliate of a Pre-Closing Holder or Sponsor, unless such Confidential
Information is actually provided to such Person.

hereunder shall terminate on the 7th anniversary of the date hereof.

 REGISTRATIONS AND OFFERINGS 

3.1 Shelf Registration. 

3.1.1 Filing. PubCo shall file and cause to be effective within 15 days of the Closing Date, a Registration Statement for a Shelf
Registration on Form S-3 (the “Form S-3 Shelf”) or if PubCo is ineligible to use a Form S-3 Shelf, a
Registration Statement for a Shelf Registration on Form S-1 (the “Form S-1 Shelf,” and together with the Form
S-3 Shelf (and any Subsequent Shelf Registration), the “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. PubCo shall use its commercially reasonable efforts to cause the Shelf to become effective as soon as practicable after such filing. The Shelf shall provide for the resale of the Registrable Securities
included therein pursuant to any method or combination of methods legally available to, and requested by, any Holder. PubCo shall maintain the Shelf in accordance with the terms hereof, and shall prepare and file with the SEC such amendments,
including post-effective 

  
 10 

 
amendments, and supplements as may be necessary to keep such 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 PubCo files a Form S-1 Shelf, PubCo 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 PubCo is eligible to use Form S-3. 

3.1.2 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, PubCo shall 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 from time to time,
and pursuant to any method or combination of methods legally available to, and requested by, any Holder. If a Subsequent Shelf Registration is filed, PubCo 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 if PubCo is a
Well-Known Seasoned Issuer) 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 PubCo is eligible to use such form. Otherwise, such Subsequent Shelf Registration shall be on another appropriate
form. In the event that any Holder holds Registrable Securities that are not registered for resale on a delayed or continuous basis, PubCo, upon request of a Holder, shall promptly use its commercially reasonable efforts to cause the resale of such
Registrable Securities to be covered by either, at PubCo’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, PubCo shall only be required to cause such Registrable Securities to be so covered once annually after reasonable inquiry of the Holders, unless
such Registrable Securities were delivered pursuant to the Merger Agreement in which case PubCo shall register such Registerable Securities so delivered as soon as reasonably possible. 

3.1.3 Requests for Underwritten Shelf Takedowns. At any time and from time to time after the Shelf has been declared
effective by the Commission, the Sponsor or any Pre-Closing Requesting Stockholder may request to sell all or any portion of its Registrable Securities in an underwritten offering that is registered pursuant
to the Shelf (each, an “Underwritten Shelf Takedown”); provided that PubCo shall only be obligated to effect an Underwritten Shelf Takedown if such offering shall include either (x) securities with a total
offering price (including piggyback securities and before deduction of underwriting discounts) reasonably expected to exceed, in the aggregate, $25,000,000 or (y) all remaining Registrable Securities held by the requesting Holder (the
“Minimum Takedown Threshold”). All requests for Underwritten Shelf Takedowns shall be made by giving written notice to PubCo, which shall specify the 

  
 11 

 
approximate number of Registrable Securities proposed to be sold in the Underwritten Shelf Takedown and the expected price range (net of underwriting discounts and commissions) of such
Underwritten Shelf Takedown. The Holders that requested such Underwritten Shelf Takedown (the “Demanding Holders”) 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 PubCo’s prior approval which shall not be unreasonably withheld, conditioned or delayed. The Sponsor may demand four Underwritten Shelf Takedowns each fiscal year and the Pre-Closing Holder Requesting Stockholders (on a collective basis) may demand four Underwritten Shelf Takedowns each fiscal year; provided, that no demand for an Underwritten Shelf Takedown may be made prior
to 45 days following the consummation of another Underwritten Shelf Takedown. 
 3.1.4 Reduction of Underwritten Offering. If the
managing Underwriter or Underwriters in an Underwritten Shelf Takedown, in good faith, advises PubCo, the Demanding Holders and the Holders requesting piggy back rights pursuant to this Investor Rights 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 shares of Common Stock or other equity securities that PubCo desires to sell and all other shares of 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 stockholders who desire to sell, 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 PubCo shall include in such Underwritten Offering, (i) the Registrable Securities that can be sold without exceeding the Maximum Number of Securities pro rata among such Holders on
the basis of the number of Registrable Securities requested to be included by each such Holder, (ii) to the extent that the Maximum Number of Securities has not been reached, the Common Stock or other equity securities of other persons or
entities that PubCo is obligated to include in such Underwritten Offering pursuant to separate written contractual arrangements with such persons and that can be sold without exceeding the Maximum Number of Securities, and (iii) to the extent
that the Maximum Number of Securities has not been reached, such number of shares of Common Stock or other equity securities proposed to be sold by PubCo until the Maximum Number of Securities is reached. Notwithstanding anything herein to the
contrary, if the Maximum Number of Securities is less than 75% of the number of Registrable Securities requested by the Holders to be included in such Underwritten Shelf Takedown, such Underwritten Shelf Takedown shall not count as an Underwritten
Shelf Takedown demanded by any Holder for purposes of Section 3.1.3. 
 3.1.5 Withdrawal. A majority-in-interest of the Demanding Holders initiating a Shelf Takedown shall have the right to withdraw from a Shelf Takedown for any or no reason whatsoever upon written notification (a
“Withdrawal Notice”) to PubCo and the Underwriter or Underwriters (if any) of their intention to withdraw from such Shelf Takedown; provided that the Sponsor or any Pre-Closing
Requesting Stockholder may elect to have PubCo continue an Underwritten Shelf Takedown if the Minimum Takedown Threshold would still be satisfied. If withdrawn, a demand for an Underwritten Shelf Takedown shall constitute a demand for an
Underwritten Shelf Takedown for purposes of subsection 3.1.3, unless either (i) the Demanding 

  
 12 

 
Holder has not previously withdrawn any Underwritten Shelf Takedown or (ii) the Holder reimburses PubCo for all Registration Expenses with respect to such Underwritten Shelf Takedown;
provided, that if a Holder elects to continue an Underwritten Shelf Takedown pursuant to the proviso in the immediately preceding sentence, such Underwritten Shelf Takedown shall count as an Underwritten Shelf Takedown demanded by such Holder
for purposes of subsection 3.1.3. Following the receipt of any Withdrawal Notice, PubCo 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 Investor Rights Agreement, PubCo shall be responsible for the Registration Expenses incurred in connection with a Shelf Takedown prior to its withdrawal under this subsection 3.1.5, other than if a Demanding Holder
elects to pay such Registration Expenses pursuant to clause (ii) of the second sentence of this subsection 3.1.5. 
 3.2
Piggyback Registration. 
 3.2.1 Piggyback Rights. If PubCo or any Holder proposes to conduct a registered offering of,
or if PubCo proposes to file a Registration Statement under the Securities Act with respect to an offering 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 stockholders of PubCo (or by PubCo and by the stockholders of PubCo including, without limitation, an Underwritten Shelf Takedown pursuant to Section 3.1 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) for an exchange offer or offering of securities solely to PubCo’s existing stockholders,
(iii) for an offering of debt that is convertible into equity securities of PubCo or (iv) for a dividend reinvestment plan, then PubCo 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 launch date of 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, a good faith estimate of the proposed maximum offering price of such securities, 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”). PubCo shall, in good faith, cause such Registrable Securities to be included in such Piggyback
Registration and shall use its best efforts to cause the managing Underwriter or Underwriters of a proposed Underwritten Offering to permit the Registrable Securities requested by the Holders pursuant to this subsection 3.2.1 to be included
in a Piggyback Registration on the same terms and conditions as any similar securities of PubCo 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 agreement to enter into an underwriting agreement in customary form with the Underwriter(s) selected for
such Underwritten Offering. Notwithstanding anything herein to the contrary, a Principal Holder effecting a Block Sale shall provide prompt written notice (but in no event later than forty-eight (48) hours prior to such Block Sale) to the
Company and any other Principal Holder setting forth the timeline for such offering to permit participation by any such other Principal Holder in such offering, and such other Principal Holder shall be entitled to participate in such offering so
long as such participation of such other Principal Holder does not materially delay the proposed timeline of such Block Sale specified in the notice. 

  
 13 

 3.2.2 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 PubCo and the Holders of Registrable Securities participating in the Piggyback Registration in writing that the dollar amount or number of shares
of Common Stock or other equity securities that PubCo desires to sell, taken together with (i) the shares of 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 3.2 hereof, and (iii) the shares of 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 stockholders of PubCo, exceeds the Maximum Number of Securities, then: 
 (a) If the Registration or registered
offering is undertaken for PubCo’s account, PubCo shall include in any such Registration or registered offering the number of shares of Common Stock or other equity securities proposed to be sold by PubCo, and thereafter, the Registrable
Securities that can be sold without exceeding the Maximum Number of Securities pro rata among such Holders on the basis of the number of Registrable Securities requested to be included by each such Holder and, to the extent that the Maximum Number
of Securities has not been reached, the shares of 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
stockholders of PubCo, 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 PubCo shall include in any such Registration or registered offering (A) first, the shares of 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 subsection 3.2.1, pro rata among such Holders on the basis of the number
of Registrable Securities requested to be included by each such Holder, 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 shares of Common Stock or other equity securities that PubCo 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 shares of Common Stock or other equity securities for the account of other persons or entities that PubCo 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. 

  
 14 

 3.2.3 Piggyback Registration Withdrawal. Any Holder of Registrable Securities shall
have the right to withdraw from a Piggyback Registration for any or no reason whatsoever upon written notification to PubCo 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. PubCo (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 Investor Rights Agreement, PubCo shall be responsible for the Registration Expenses incurred in connection with the Piggyback Registration prior to its withdrawal under this
subsection 3.2.3. 
 3.2.4 Unlimited Piggyback Registration Rights. For purposes of clarity, subject to subsection 3.1.5
any Piggyback Registration effected pursuant to Section 3.2 hereof shall not be counted as a demand for an Underwritten Shelf Takedown under subsection 3.1.3 hereof. 

3.3 In connection with any Underwritten Offering of equity securities of PubCo, each Holder agrees that it shall not transfer any shares of
Common Stock (other than those included in such offering pursuant to this Investor Rights Agreement), without the prior written consent of PubCo, during the seven days prior to and the 90-day period beginning
on the date of pricing of such offering, except in the event the Underwriters managing the offering otherwise agree by written consent. Each 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). Notwithstanding the foregoing, with respect to an Underwritten Offering, a Holder shall not be subject to this Section 3.3 with
respect to an Underwritten Offering unless each stockholder of PubCo that (together with their affiliates) hold at least 5% of the issued and outstanding Common Stock and each of PubCo’s directors and officers have executed a lock-up on terms at least as restrictive with respect to such Underwritten Offering as requested of the Holders. A Holder’s obligations under this Section 3.3 shall only apply for so long as such Holder
(together with its affiliates) holds at least 5% of the issued and outstanding Common Stock. 
 ARTICLE IV

4.1.4 prior to any public offering of Registrable Securities, use its best efforts to (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 PubCo and do any and all other acts and things that may be

 16 

 4.1.9 notify the Holders at any time when a Prospectus relating to such Registration

Misstatement as set forth in Section 4.4 hereof; 
 4.1.10 permit a representative of the Holders (such
representative to be selected by a majority of the participating Holders), the Underwriters, if any, and any attorney or accountant retained by such Holders or Underwriter to participate, at each such person’s own expense, in the preparation of
the Registration Statement, and cause PubCo’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 PubCo, prior to the release or disclosure of any such information; and provided further, PubCo may not include
the name of any Holder or any information regarding any Holder in any Registration Statement or Prospectus, any amendment or supplement to such Registration Statement or Prospectus, any document into such Registration Statement or Prospectus, or any
response to any comment letter, without the prior written consent of such Holder and providing each such Holder a reasonable amount of time to review and comment on such applicable document, which comments PubCo shall include unless contrary to
applicable law; 
 4.1.11 obtain a “cold comfort” letter from PubCo’s independent registered public accountants in the event
of an Underwritten Offering, in customary form and covering such matters of the type customarily covered by “cold comfort” letters as the managing Underwriter may reasonably request, and reasonably satisfactory to a majority-in-interest of the participating Holders; 
 4.1.12 on the
date the Registrable Securities are delivered for sale pursuant to such Registration, obtain an opinion, dated such date, of counsel representing PubCo 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; 

4.1.13 in the event of any Underwritten Offering, enter into and perform its obligations under an underwriting agreement, in usual and
customary form, with the managing Underwriter of such offering; 
 4.1.14 make available to its security holders, as soon as reasonably

 17 

 4.1.15 if an Underwritten Offering involves Registrable Securities with a total offering
price (including piggyback securities and before deduction of underwriting discounts) reasonably expected to exceed, in the aggregate, $35.0 million, use its reasonable efforts to make available senior executives of PubCo to participate in
customary “road show” presentations that may be reasonably requested by the Underwriter in such Underwritten Offering; and 

4.1.16 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. 
 4.2 Registration Expenses. Except as otherwise provided herein, the Registration Expenses of all
Registrations shall be borne by PubCo. 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’ commissions and discounts, brokerage
fees and, other than as set forth in the definition of “Registration Expenses,” all reasonable fees and expenses of any legal counsel representing the Holders. 

4.3 Requirements for Participation in Underwritten Offerings. Notwithstanding anything in this Investor Rights Agreement to the
contrary, if any Holder does not provide PubCo with its requested Holder Information, PubCo may exclude such Holder’s Registrable Securities from the applicable Registration Statement or Prospectus if PubCo 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 for equity securities of PubCo pursuant to a
Registration initiated by PubCo hereunder unless such person (i) agrees to sell such person’s securities on the basis provided in any underwriting arrangements approved by PubCo and (ii) completes and executes all customary
questionnaires, powers of attorney, indemnities, lock-up agreements, underwriting agreements and other customary documents as may be reasonably required under the terms of such underwriting arrangements. The
exclusion of a Holder’s Registrable Securities as a result of this Section 4.3 shall not affect the registration of the other Registrable Securities to be included in such Registration. 

4.4 Suspension of Sales; Adverse Disclosure. Upon receipt of written notice from PubCo 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 PubCo 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 PubCo that the use of the Prospectus may be resumed. If the filing, initial effectiveness or
continued use of a Registration Statement in respect of any Registration at any time would require PubCo to make an Adverse Disclosure or would require the inclusion in such Registration Statement of financial statements that are unavailable to
PubCo for reasons beyond PubCo’s control, PubCo 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,
but in no event more than thirty (30) days, determined in good faith by PubCo to be necessary for such purpose; provided that such right to delay or suspend shall be exercised by PubCo not more than three (3) times in any
twelve-month period. In the event PubCo exercises its rights under the preceding sentence, 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. PubCo shall immediately notify the Holders of the expiration of any period during which it exercised its rights under this Section 4.4. 

  
 18 

 4.5 Reporting Obligations. As long as any Holder shall own Registrable Securities,
PubCo, 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 PubCo 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 4.5. PubCo 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 shares of Common Stock 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), including providing any legal opinions. Upon the request of any Holder, PubCo shall deliver to such Holder a written certification of a duly authorized officer as
to whether it has complied with such requirements. 
 4.6 Other Obligations. In connection with a sale or transfer of
Registrable Securities exempt from Section 5 of the Securities Act or through any broker-dealer transactions described in the plan of distribution set forth within the Prospectus and pursuant to the Registration Statement of which such
Prospectus forms a part, PubCo shall, subject to the receipt of the any customary documentation required from the applicable Holders in connection therewith, (i) promptly instruct its transfer agent to remove any restrictive legends applicable
to the Registrable Securities being sold or transferred and (ii) cause its legal counsel to deliver the necessary legal opinions, if any, to the transfer agent in connection with the instruction under subclause (i). In addition, PubCo shall
cooperate reasonably with, and take such customary actions as may reasonably be requested by the Holders, in connection with the aforementioned sales or transfers; provided, however, that PubCo shall have no obligation to participate in any
“road shows” or assist with the preparation of any offering memoranda or related documentation with respect to any sale or transfer of Registrable Securities in any transaction that does not constitute an Underwritten Offering. 

4.7 Transfer Restrictions. 

4.7.1 During the Lock-Up Period, none of the Holders shall offer, sell, contract to sell, pledge, grant
any option to purchase, make any short sale or otherwise dispose of or distribute any shares of Common Stock that are subject to the Lock-Up Period or any securities convertible into, exercisable for,
exchangeable for or that represent the right to receive shares of Common Stock that are subject to the Lock-Up Period, whether now owned or hereinafter acquired, that is owned directly by such Holder
(including securities held as a custodian) or with respect to which such Holder has beneficial ownership within the rules and regulations of the Commission (such securities that are subject to the Lock-Up
Period, the “Restricted Securities”), other than (i) any transfer to an affiliate of a Holder, (ii) a distribution to profit interest holders, limited partners, member, shareholder or other equity holders of or
other holders of equity interests in such Holder or (iii) as a pledge in a bona fide transaction to third parties as collateral to secure 

  
 19 

 
obligations pursuant to lending or other arrangements with such third parties relating to a financing arrangement for the benefit of the Holder or its affiliates, as applicable. The foregoing
restriction is expressly agreed to preclude each Holder, as applicable, from engaging in any hedging or other transaction with respect to Restricted Securities which is designed to or which reasonably could be expected to lead to or result in a sale
or disposition of the Restricted Securities even if such Restricted Securities would be disposed of by someone other than such Holder. Such prohibited hedging or other transactions include any short sale or any purchase, sale or grant of any right
(including any put or call option) with respect to any of the Restricted Securities of the applicable Holder, or with respect to any security that includes, relates to, or derives any significant part of its value from such Restricted Securities.

 4.7.2 Each Holder hereby represents and warrants that it now has and, except as contemplated by subsection 4.7.1 or this
subsection 4.7.2 for the duration of the Lock-Up Period, will have good and marketable title to its Restricted Securities, free and clear of all liens, encumbrances, and claims that could impact
the ability of such Holder to comply with the foregoing restrictions Each Holder agrees and consents to the entry of stop transfer instructions with PubCo’s transfer agent and registrar against the transfer of any Restricted Securities during
the Lock-Up Period. 
 ARTICLE V 

INDEMNIFICATION AND CONTRIBUTION 

5.1 Indemnification. 

5.1.1 PubCo agrees to indemnify, to the extent permitted by law, each Holder of Registrable Securities, its officers and directors and each
person who controls such Holder (within the meaning of the Securities Act) against all losses, claims, damages, liabilities and expenses (including attorneys’ fees) caused by 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, in the
case of the Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto, in light of the circumstances under which it was made, not misleading, except insofar as the same are caused by or contained in any information
furnished in writing to PubCo by such Holder expressly for use therein. PubCo shall indemnify the Underwriters, their officers and 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 the indemnification of the Holder. 
 5.1.2 In connection with any Registration Statement in
which a Holder of Registrable Securities is participating, such Holder shall furnish to PubCo in writing such information and affidavits as PubCo 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 PubCo, its directors, officers and agents and each person who controls PubCo (within the meaning of the Securities Act) against any losses, claims,
damages, liabilities and expenses (including without limitation reasonable attorneys’ fees) resulting from any untrue statement of material fact contained in the Registration Statement, Prospectus or preliminary Prospectus or any amendment
thereof or supplement thereto or any omission of a material fact 

  
 20 

 
required to be stated therein or necessary to make the statements therein, in the case of the Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto, in light of the
circumstances under which it was made, not misleading, but only to the extent that such untrue statement or 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 PubCo. 

5.1.3 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 (and, if necessary, one local counsel), 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. 
 5.1.4 The indemnification provided for under this Investor Rights 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. 

5.1.5 If the indemnification provided under Section 5.1 hereof from the indemnifying party is unavailable or
insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities and 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 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 

  
 21 

 
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 subsection 5.1.5 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 subsections 5.1.1, 5.1.2 and 5.1.3 above, any legal or other fees, charges or 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 subsection 5.1.5 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 subsection 5.1.5. 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 subsection 5.1.5 from any person
who was not guilty of such fraudulent misrepresentation.

presentation. Any notice or communication under this Investor Rights Agreement must be addressed, if to PubCo to: King Pubco, Inc., 875 3rd Avenue, 11th Floor, New York, NY 10022, Attn: Nick Robinson, Mike Palmer,
E-mail: nrobinson@cerberus.com, mpalmer@cerberus.com, and, if to any Holder, at such Holder’s address or facsimile number as set forth in PubCo’s books and records. Any party may change its address
for notice at any time and from time to time by written notice to the other parties hereto, and such change of address shall become effective thirty (30) days after delivery of such notice as provided in this
Section 6.1. 
 6.2 Representations and Warranties of the Parties. Each of the Parties hereby represents and
warrants to each of the other Parties as follows: 
 6.3.1 Such Party, to the extent applicable, is duly organized or incorporated, validly
existing and in good standing under the laws of the jurisdiction of its organization or incorporation and has all requisite power and authority to conduct its business as it is now being conducted and is proposed to be conducted. 

  
 22 

 6.3.2 Such Party has the full power, authority and legal right to execute,
deliver and perform this Investor Rights Agreement. The execution, delivery and performance of this Investor Rights Agreement have been duly authorized by all necessary action, corporate or otherwise, of such Party. This Investor Rights Agreement
has been duly executed and delivered by such Party and constitutes its, his or her legal, valid and binding obligation, enforceable against it, him or her in accordance with its terms, subject to applicable bankruptcy, insolvency and similar laws
affecting creditors’ rights generally. 
 6.3.3 The execution and delivery by such Party of this Investor Rights
Agreement, the performance by such Party of its, his or her obligations hereunder by such Party does not and will not violate (i) in the case of Parties who are not individuals, any provision of its
by-laws, charter, articles of association, partnership agreement or other similar organizational document, (ii) any provision of any material agreement to which it, he or she is a Party or by which it, he
or she is bound or (iii) any law, rule, regulation, judgment, order or decree to which it, he or she is subject. 

6.3.4 Such Party is not currently in violation of any law, rule, regulation, judgment, order or decree, which violation could
reasonably be expected at any time to have a material adverse effect upon such Party’s ability to enter into this Investor Rights Agreement or to perform its, his or her obligations hereunder. 

6.3.5 There is no pending legal action, suit or proceeding that would materially and adversely affect the ability of such Party
to enter into this Investor Rights Agreement or to perform its, his or her obligations hereunder. 
 6.4 Specific Performance.
Each Party hereby agrees and acknowledges that it will be impossible to measure in money the damages that would be suffered if the Parties fail to comply with any of the obligations imposed on them by this Investor Rights Agreement (including the
failure to take such actions as are required of them under this Investor Rights Agreement) and that, in the event of any such failure, an aggrieved Party will be irreparably damaged and will not, even if available, have an adequate remedy at Law.
Any such Party shall, therefore, be entitled (in addition to any other remedy to which such Party may be entitled at Law or in equity) to injunctive relief, specific performance, or other equitable relief to prevent breaches of this Investor Rights
Agreement and to enforce such obligations, without the posting of any bond or other security and without proof of damages, this being in addition to any other remedy to which they are entitled under this Investor Rights Agreement, and if any Action
should be brought in equity to enforce any of the provisions of this Investor Rights Agreement, none of the Parties shall oppose the granting of specific performance and other equitable relief on the basis that the other Parties have an adequate
remedy at Law. Further, each Party agrees and acknowledges that the right of specific enforcement is an integral part of this Investor Rights Agreement and without that right, none of the Parties would have entered into this Investor Rights
Agreement. 
 6.5 Subsequent Acquisition of Shares. Any Equity Securities of PubCo acquired subsequent to the Effective Date by
a Holder shall be subject to the terms and conditions of this Investor Rights Agreement and such shares shall be considered to be “Registrable Securities” as such term is used in this Investor Rights Agreement. 

  
 23 

 6.6 Consents, Approvals and Actions. If any consent, approval or action of the
Sellers or the Sponsor is required at any time pursuant to this Investor Rights Agreement, such consent, approval or action shall be deemed given if the holders of a majority of the outstanding Equity Securities of PubCo held by the Pre-Closing Stockholders or the Sponsor, as applicable, at such time provide such consent, approval or action in writing at such time. 

6.7 Not a Group; Independent Nature of Holders’ Obligations and Rights. The Holders and PubCo agree
that the arrangements contemplated by this Investor Rights Agreement are not intended to constitute the formation of a “group” (as defined in Section 13(d)(3) of the Exchange Act). Each Holder agrees that, for purposes of determining
beneficial ownership of such Holder, it shall disclaim any beneficial ownership by virtue of this Investor Rights Agreement of PubCo’s Equity Securities owned by the other Holders, and PubCo agrees to recognize such disclaimer in its Exchange
Act and Securities Act reports. The obligations of each Holder under this Investor Rights Agreement are several and not joint with the obligations of any other Holder, and no Holder shall be responsible in any way for the performance of the
obligations of any other Holder under this Investor Rights Agreement. Nothing contained herein, and no action taken by any Holder pursuant hereto, shall be deemed to constitute the Holders as, and PubCo acknowledges that the Holders do not so
constitute, a partnership, an association, a joint venture or any other kind of group or entity, or create a presumption that the Holders are in any way acting in concert or as a group or entity with respect to such obligations or the transactions
contemplated by this Investor Rights Agreement, and PubCo acknowledges that the Holders are not acting in concert or as a group, and PubCo shall not assert any such claim, with respect to such obligations or the transactions contemplated by this
Investor Rights Agreement. The decision of each Holder to enter into this Investor Rights Agreement has been made by such Holder independently of any other Holder. Each Holder acknowledges that no other Holder has acted as agent for such Holder in
connection with such Holder making its investment in PubCo and that no other Holder will be acting as agent of such Holder in connection with monitoring such Holder’s investment in the Common Stock or enforcing its rights under this Investor
Rights Agreement. PubCo and each Holder confirms that each Holder has had the opportunity to independently participate with PubCo and its subsidiaries in the negotiation of the transaction contemplated hereby with the advice of its own counsel and
advisors. Each Holder shall be entitled to independently protect and enforce its rights, including, without limitation, the rights arising out of this Investor Rights Agreement, and it shall not be necessary for any other Holder to be joined as an
additional party in any proceeding for such purpose. The use of a single agreement to effectuate the rights and obligations contemplated hereby was solely in the control of PubCo, not the action or decision of any Holder, and was done solely for the
convenience of PubCo and its subsidiaries and not because it was required to do so by any Holder. It is expressly understood and agreed that each provision contained in this Investor Rights Agreement is between PubCo and a Holder, solely, and not
between PubCo and the Holders collectively and not between and among the Holders. 
 6.8 Other Business Opportunities.

 6.8.1 The Parties expressly acknowledge and agree that to the fullest extent permitted by applicable law: (i) each of
the Pre-Closing Stockholders and the Sponsor (including in the case of Abry and Sponsor, (A) its Affiliates, (B) any portfolio company in which it or any of its investment fund Affiliates have made a
debt or equity investment (and vice versa) or (C) any of their respective limited partners, non-managing members or other similar direct or indirect investors) and the
Pre-Closing Holder Directors and the Sponsor Directors has the right to, and shall have no duty (fiduciary, contractual or 

  
 24 

 
otherwise) not to, directly or indirectly engage in and possess interests in other business ventures of every type and description, including those engaged in the same or similar business
activities or lines of business as PubCo or any of its subsidiaries or deemed to be competing with PubCo or any of its subsidiaries, on its own account, or in partnership with, or as an employee, officer, director or shareholder of any other Person,
with no obligation to offer to PubCo or any of its subsidiaries, or any other Holder the right to participate therein; (ii) each of the Pre-Closing Stockholders and the Sponsor (including in the case of
Abry and Sponsor, (A) its Affiliates, (B) any portfolio company in which it or any of its investment fund Affiliates have made a debt or equity investment (and vice versa) or (C) any of their respective limited partners, non-managing members or other similar direct or indirect investors) and the Pre-Closing Holder Designated Directors and the Sponsor Designated Directors may invest in, or
provide services to, any Person that directly or indirectly competes with PubCo or any of its subsidiaries; and (iii) in the event that any of the Pre-Closing Stockholders and the Sponsor (including in
the case of Abry and Sponsor, (A) its Affiliates, (B) any portfolio company in which it or any of its investment fund Affiliates have made a debt or equity investment (and vice versa) or (C) any of their respective limited partners, non-managing members or other similar direct or indirect investors) or any Pre-Closing Holder Designated Director or Sponsor Designated Director, respectively, acquires
knowledge of a potential transaction or matter that may be a corporate or other business opportunity for PubCo or any of its subsidiaries, such Person shall have no duty (fiduciary, contractual or otherwise) to communicate or present such corporate
opportunity to PubCo or any of its subsidiaries or any other Holder, as the case may be, and, notwithstanding any provision of this Investor Rights Agreement to the contrary, shall not be liable to PubCo or any of its subsidiaries or any other
Holder (or its Affiliates) for breach of any duty (fiduciary, contractual or otherwise) by reason of the fact that such Person, directly or indirectly, pursues or acquires such opportunity for itself, directs such opportunity to another Person or
does not present such opportunity to PubCo or any of its subsidiaries or any other Holder (or its Affiliates). For the avoidance of doubt, the Parties acknowledge that this paragraph is intended to disclaim and renounce, to the fullest extent
permitted by applicable law, any right of PubCo or any of its subsidiaries with respect to the matters set forth herein, and this paragraph shall be construed to effect such disclaimer and renunciation to the fullest extent permitted by law. 

6.8.2 Each of the Parties hereby, to the fullest extent permitted by applicable law: 

(a) confirms that none of the Pre-Closing Stockholders or the Sponsor or any of their respective
Affiliates have any duty to PubCo or any of its subsidiaries or to any other Holder other than the specific covenants and agreements set forth in this Investor Rights Agreement; 

(b) acknowledges and agrees that (A) in the event of any conflict of interest between PubCo or any of its subsidiaries, on the one hand,
and any of the Pre-Closing Stockholders, the Sponsor or any of their respective Affiliates (or any Pre-Closing Holder Director or Sponsor Director acting in his or her
capacity as such), on the other hand, the Pre-Closing Stockholders, the Sponsor or applicable Affiliates (or any Pre-Closing Holder Director or Sponsor Director acting
in his or her capacity as a director) may act in its best interest and (B) none of the Pre-Closing Stockholders, the Sponsor or any of their respective Affiliates or any
Pre-Closing 

  
 25 

 
Holder Director or Sponsor Director acting in his or her capacity as a director, shall be obligated (1) to reveal to PubCo or any of its subsidiaries confidential information belonging to or
relating to the business of such Person or any of its Affiliates or (2) to recommend or take any action in its capacity as a direct or indirect stockholder or director, as the case may be, that prefers the interest of PubCo or its subsidiaries
over the interest of such Person; and 
 (c) waives any claim or cause of action against any of the
Pre-Closing Stockholders, the Sponsor and any of their respective Affiliates, and any officer, employee, agent or Affiliate of any such Person that may from time to time arise in respect of a breach by any
such person of any duty or obligation disclaimed under Section 6.8.2(a) or Section 6.8.2(b). 

6.8.3 Each of the parties hereto agrees that the waivers, limitations, acknowledgments and agreements set forth in this
Section 6.8 shall not apply to any alleged claim or cause of action against any of the Pre-Closing Stockholders or the Sponsor based upon the breach or nonperformance by such Person
of this Investor Rights Agreement or any other agreement to which such Person is a party. 
 6.8.4 The provisions of this
Section 6.8, to the extent that they restrict the duties and liabilities of any of the Pre-Closing Stockholders, the Sponsor or any of their respective Affiliates or any Pre-Closing Holder Director or Sponsor Director otherwise existing at law or in equity, are agreed by the Parties to replace such other duties and liabilities of the
Pre-Closing Stockholders, the Sponsor or any of their respective Affiliates or any such Pre-Closing Holder Director or Sponsor Director to the fullest extent permitted
by applicable law. 
 6.9 Assignment; No Third Party Beneficiaries. 

6.9.1 This Agreement and the rights, duties and obligations of PubCo hereunder may not be assigned or delegated by PubCo in whole or in part.

 6.9.2 Prior to the expiration of any Lock-up Period, no Holder subject to any such Lock-Up Period may assign or delegate such Holder’s rights, duties or obligations under this Investor Rights Agreement, in whole or in part, in violation of the applicable
Lock-Up Period, except to (a) an Affiliate of such Holder, (b) direct and/or indirect equity holders of the Sponsor pursuant to a distribution as described in Section 6.19
of this Investor Rights Agreement or to direct or indirect equity holders of any Pre-Closing Stockholder or (c) any person with the prior written consent of PubCo. A sale or transfer that qualifies
pursuant to an exemption from the Securities Act shall not be deemed to have been made pursuant to a registration statement. 
 6.9.3 After
the expiration of the Lock-up Period to the extent applicable to such Holder, a Holder may assign or delegate such Holder’s rights, duties or obligations under this Investor Rights Agreement, in whole or
in part, to (a) up to five Permitted Transferees, provided, however, that each such Permitted Transferee holds, after giving effect to such assignment or delegation, at least five percent of the then-outstanding Common Shares, (b) an
Affiliate of such Holder, (c) direct and/or indirect equity holders of the Sponsor pursuant to a distribution as described in Section 6.19 of this Investor Rights Agreement or to direct or indirect equity holders of
any Pre-Closing Stockholder or (d) any person with the prior written consent of PubCo. 

  
 26 

 6.9.4 This Agreement and the provisions hereof shall be binding upon and shall inure to the
benefit of each of the parties and its successors and the permitted assigns of the Holders, which shall include Permitted Transferees. 

6.9.5 This Agreement shall not confer any rights or benefits on any persons that are not parties hereto, other than as expressly set forth in
this Investor Rights Agreement (including pursuant to Sections 2.2.8, 2.2.9, 5.1, 6.8 and 6.19 hereof). 

6.9.6 No assignment by any party hereto of such party’s rights, duties and obligations hereunder shall be binding upon or obligate PubCo
unless and until PubCo shall have received (i) written notice of such assignment as provided in Section 6.1 hereof and (ii) the written agreement of the assignee, in a form reasonably satisfactory to PubCo, to be
bound by the terms and provisions of this Investor Rights Agreement (which may be accomplished by an addendum or certificate of joinder to this Investor Rights Agreement). Any transfer or assignment made other than as provided in this
Section 6.9 shall be null and void. 
 6.10 Counterparts. This Agreement may be executed in multiple
counterparts (including facsimile or PDF counterparts), each of which shall be deemed an original, and all of which together shall constitute the same instrument, but only one of which need be produced. 

6.11 Governing Law; Venue. NOTWITHSTANDING THE PLACE WHERE THIS AGREEMENT MAY BE EXECUTED BY ANY OF THE PARTIES HERETO, THE PARTIES
EXPRESSLY AGREE THAT (I) THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED UNDER THE LAWS OF THE STATE OF NEW YORK AS APPLIED TO AGREEMENTS AMONG NEW YORK RESIDENTS ENTERED INTO AND TO BE PERFORMED ENTIRELY WITHIN NEW YORK, WITHOUT REGARD TO
THE CONFLICT OF LAW PROVISIONS OF SUCH JURISDICTION AND (II) THE VENUE FOR ANY ACTION TAKEN WITH RESPECT TO THE AGREEMENT SHALL BE ANY STATE OR FEDERAL COURT IN NEW YORK COUNTY IN THE STATE OF NEW YORK. 

6.12 TRIAL BY JURY. EACH PARTY HERETO ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS
LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND, THEREFORE, EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT TO ANY
ACTION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. 

6.13 Amendments and Modifications. Upon the written consent of each of the Principal Holders, compliance with any of the provisions,
covenants and conditions set forth in this Investor Rights Agreement may be waived, or any of such provisions, covenants or conditions may be amended or modified; provided, however, that notwithstanding the foregoing, any amendment hereto or waiver
hereof that adversely affects one Holder, solely in its capacity as a holder of the shares of capital stock of PubCo, in a manner that is materially different from the other Holders (in such capacity) shall require the consent of the Holder so
affected. No course of dealing between 

  
 27 

 
any Holder or PubCo and any other party hereto or any failure or delay on the part of a Holder or PubCo in exercising any rights or remedies under this Investor Rights Agreement shall operate as
a waiver of any rights or remedies of any Holder or PubCo. No single or partial exercise of any rights or remedies under this Investor Rights 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. 
 6.14 Other Registration Rights. PubCo represents and warrants that no person, other than a
Holder of Registrable Securities, has any right to require PubCo to register any securities of PubCo for sale or to include such securities of PubCo in any Registration Statement filed by PubCo for the sale of securities for its own account or for
the account of any other person. Further, PubCo represents and warrants that this Investor Rights Agreement supersedes any other registration rights agreement or agreement with similar terms and conditions, including the RRA, and in the event of a
conflict between any such agreement or agreements and this Investor Rights Agreement, the terms of this Investor Rights Agreement shall prevail. PubCo agrees that (i) it shall not hereafter enter into any agreement with respect to its
securities which is inconsistent with or violates the rights granted to the Holders hereunder, and (ii) it shall not grant any registration rights to third parties which are more favorable than the rights granted hereunder unless are such more
favorable rights are concurrently added to the rights granted hereunder. 
 6.15 Termination of RRA. Upon the Closing, PubCo and the
Original Holders hereby agree that the RRA and all of the respective rights and obligations of the parties thereunder are hereby terminated in their entirety and shall be of no further force or effect. 

6.16 Term. Except for Section 2.2.10 (which section shall terminate at such time as the Pre-Closing Stockholders, the Sponsor and their Permitted Transferees are no longer entitled to any rights pursuant to such section), Article II shall terminate automatically (without any action by any Party)
as to the Pre-Closing Stockholders or the Sponsor at such time at which such Party no longer has the right to designate an individual for nomination to the Board under this Investor Rights Agreement.
Article III, Article IV, and Article V of this Investor Rights Agreement shall terminate with respect to any Holder on the date that such Holder no longer holds any Registrable Securities except that the provisions of Article
V shall survive any termination. The remainder of this Investor Rights Agreement shall terminate automatically (without any action by any Party) as to each Holder when such Holder, following the Closing Date, ceases to Beneficially Own any
Registrable Securities. 
 6.17 Holder Information. Each Holder agrees, if requested in writing, to represent to PubCo the
total number of Registrable Securities held by such Holder in order for PubCo to make determinations hereunder, including, without limitation, for purposes of Section 6.16 hereof. 

6.18 Joinder. Each Pre-Closing Stockholder that is not a party to this Investor Rights
Agreement as of the date hereof shall have the right to become a party to this Investor Rights Agreement after the date hereof as though an original party hereto, upon execution and delivery to PubCo of a joinder agreement, in a form reasonably
satisfactory to PubCo. Upon the execution and delivery of a joinder agreement in accordance with the immediately preceding sentence, the joining party shall become a “Holder” and shall be entitled, in addition to those rights as a
Holder, to any rights of a “Pre-Closing Stockholder” under this Investor Rights Agreement. 

  
 28 

 6.19 Distributions. In the event that the Sponsor distributes, or has distributed,
all of its Registrable Securities to its direct and/or indirect equity holders, such distributees shall be treated as the Sponsor hereunder; provided, however, that Sponsor shall remain as the representative acting on behalf of such distributees and
shall be able to confer all rights and take all actions on behalf of such distributees; provided that such distributees, taken as a whole, shall not be entitled to rights in excess of those conferred to the Sponsor, as if it remained a single entity
party to this Investor Rights Agreement. 
 6.20 Legends. Without limiting the obligations of PubCo set forth in
Section 4.6, each of the Holders acknowledges that (i) no Transfer, hypothecation or assignment of any Registrable Securities Beneficially Owned by such Holder may be made except in compliance with applicable federal and state
securities laws and (ii) PubCo shall (x) place customary restrictive legends on the certificates or book entries representing the Registrable Securities subject to this Investor Rights Agreement and (y) remove such restrictive
legends at the time the applicable Transfer and other restrictions contemplated thereby are no longer applicable to the Registrable Securities represented by such certificates or book entries. 

6.22 Adjustments. If, and as often as, there are any changes in the shares of Common Stock by way of stock split, stock dividend,
combination or reclassification, or through merger, consolidation, reorganization, recapitalization or sale, or by any other means, appropriate adjustment shall be made in the provisions of this Investor Rights Agreement, as may be required, so that
the rights, privileges, duties and obligations hereunder shall continue with respect to the shares of Common Stock as so changed.

 Execution Version 

SUBSCRIPTION AGREEMENT 

This SUBSCRIPTION AGREEMENT (this “Subscription Agreement”) is entered into this 12th day of March, 2021, by and among
Cerberus Telecom Acquisition Corp., a Cayman Islands exempted company (the “Issuer”), King Pubco, Inc., a Delaware corporation (“Pubco”), and the undersigned (“Subscriber” or
“you”). Defined terms used but not otherwise defined herein shall have the respective meanings ascribed thereto in the Merger Agreement (as defined below). 

WHEREAS, the Issuer, Pubco, King Corp Merger Sub, Inc. (“Corp Merger Sub”), King LLC Merger Sub, LLC (“LLC Merger
Sub”) and Maple Holdings Inc., a Delaware corporation (the “Company”) will concurrently with the execution of this Subscription Agreement, enter into that certain Agreement and Plan of Merger, dated as of the date hereof
(as amended, amended and restated, modified, supplemented, or waived from time to time in accordance with its terms, the “Merger Agreement”), pursuant to which, inter alia, (i) on the day immediately prior to the Closing
Date, Issuer will be merged with and into LLC Merger Sub, with LLC Merger Sub surviving as a wholly owned subsidiary of Pubco (the “Pubco Merger”), (ii) on the Closing Date, Corp Merger Sub, a direct, wholly owned subsidiary
of Pubco (after giving effect to the Corp Merger Sub Contribution) will be merged with and into the Company, with the Company surviving as a wholly owned subsidiary of Pubco (the “First Merger”), and (iii) immediately after the
First Merger, the Company will be merged with and into LLC Merger Sub, a direct, wholly owned subsidiary of Pubco, with LLC Merger Sub surviving as a wholly owned subsidiary of Pubco, in each case on the terms and subject to the conditions set forth
in the Merger Agreement (all of the foregoing mergers together with the other transactions contemplated by the Merger Agreement, the “Transactions”); 

WHEREAS, in connection with the Pubco Merger, each Class A ordinary share of the Issuer, par value $0.0001 per share
(“Class A Ordinary Share”) shall convert into one share of class A common stock, par value $0.0001 of Pubco, which after giving effect to the Transactions, will become common stock of Pubco (the
“Shares”); 
 WHEREAS, prior to the closing of the Transactions, Subscriber desires to subscribe for and purchase from
Pubco that number of Shares set forth on Subscriber’s signature page hereto for a purchase price of $10.00 per share, for the aggregate purchase price set forth on Subscriber’s signature page hereto (the “Purchase Price”),
and Pubco desires to issue, in book entry form, and sell to Subscriber the Shares in consideration of the payment of the Purchase Price therefor by or on behalf of Subscriber to Pubco, all on the terms and conditions set forth herein; and 

WHEREAS, certain other “qualified institutional buyers” (as defined in Rule 144A under the Securities Act of 1933, as amended (the
“Securities Act”)) or institutional “accredited investors” (within the meaning of Rule 501(a)(1), (2), (3) and (7) under the Securities Act) (each, an “Other Subscriber”) have, severally and not
jointly, entered into separate subscription agreements with the Issuer and Pubco (the “Other Subscription Agreements”), pursuant to which such Other Subscribers have agreed to purchase the Shares on the Closing Date (as defined
herein) at the same per share purchase price as the Subscriber, and the aggregate number of Shares to be sold by Pubco pursuant to this Subscription Agreement and the Other Subscription Agreements equals, as of the date hereof, 22,500,000 Shares.

 NOW, THEREFORE, in consideration of the foregoing and the mutual representations, warranties, and covenants, and subject to the
conditions, herein contained, and intending to be legally bound hereby, the parties hereto hereby agree as follows: 
 1.
Subscription. Subject to the terms and conditions hereof, at the Closing (as defined below), Subscriber hereby agrees to subscribe for and purchase from Pubco, and Pubco hereby agrees to issue and sell to Subscriber, upon and subject to the
payment of the Purchase Price, the Shares (such subscription and issuance, the “Subscription”). Notwithstanding anything herein to the contrary, the consummation of the Subscription is contingent upon the subsequent occurrence of
the closing of the Transactions as further described herein. 

 2. Representations, Warranties, and Agreements. 

2.1 Subscriber’s Representations, Warranties, and Agreements. To induce Pubco to issue the Shares to Subscriber, Subscriber hereby
represents and warrants to the Issuer and Pubco and acknowledges and agrees with the Issuer and Pubco, as of the date hereof and as of the Closing, as follows: 

2.1.1 If Subscriber is not an individual, Subscriber has been duly formed or incorporated and is validly existing and in good standing under
the laws of its jurisdiction of incorporation or formation, with power and authority to enter into, deliver, and perform its obligations under this Subscription Agreement. If Subscriber is an individual, Subscriber has the authority to enter into,
deliver, and perform its obligations under this Subscription Agreement. 
 2.1.2 If Subscriber is not an individual, this Subscription
Agreement has been duly authorized, validly executed and delivered by Subscriber. If Subscriber is an individual, the signature on this Subscription Agreement is genuine, and Subscriber has legal competence and capacity to execute the same. Assuming
that this Subscription Agreement constitutes the valid and binding agreement of the Issuer and Pubco, this Subscription Agreement is the valid and binding obligation of Subscriber and is enforceable against Subscriber in accordance with its terms,
except as may be limited or otherwise affected by (i) bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium, or other laws relating to or affecting the rights of creditors generally and (ii) principles of equity,
whether considered at law or equity. 
 2.1.3 The execution, delivery and performance by Subscriber of this Subscription Agreement and the
consummation of the transactions contemplated herein do not and will not (i) conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default or waiver under, or result in the creation or imposition
of any lien, charge, or encumbrance upon any of the property or assets of Subscriber pursuant to the terms of any indenture, mortgage, deed of trust, loan agreement, lease, license, or other agreement or instrument to which Subscriber is a party, or
by which Subscriber is bound or to which any of the property or assets of Subscriber is subject, which would, in each case, reasonably be expected to have a materially adverse effect on the ability of Subscriber to enter into and timely perform its
obligations under this Subscription Agreement, (ii) if Subscriber is not an individual, result in any violation of the provisions of the organizational documents of Subscriber or (iii) result in any violation of any statute or any
judgment, order, rule, or regulation of any court or governmental agency or body, domestic or foreign, having jurisdiction over Subscriber or any of its properties, which would, in each case, reasonably be expected to have a materially adverse
effect on the ability of Subscriber to enter into and timely perform its obligations under this Subscription Agreement. 
 2.1.4 Subscriber
(i) is a “qualified institutional buyer” (as defined in Rule 144A under the Securities Act) or an institutional “accredited investor” (within the meaning of Rule 501(a) (1), (2), (3) or (7) under the Securities Act)
satisfying the applicable requirements set forth on Schedule I attached hereto, (ii) is an institutional account as defined in FINRA Rule 4512(c), (iii) is acquiring the Shares only for its own account or for beneficiaries’
portfolio under its management and not for the account of others, or if Subscriber is subscribing for the Shares as a fiduciary or agent for one or more investor accounts, each owner of such account is a qualified institutional buyer, and Subscriber
has full investment discretion with respect to each such account, and the full power and authority to make the acknowledgements, representations, warranties, and agreements herein on behalf of each owner of each such account, and (iv) is not
acquiring the Shares with a view to, or for offer or sale in connection with, any distribution thereof in violation of the Securities Act (and shall provide the requested information on Schedule I attached hereto). Subscriber is not an entity
formed for the specific purpose of acquiring the Shares. 

  
 2 

 2.1.5 Subscriber understands that the Shares are being offered in a transaction not
involving any public offering within the meaning of the Securities Act and that the Shares have not been registered under the Securities Act. Subscriber understands that the Shares may not be resold, transferred, pledged, or otherwise disposed of by
Subscriber absent an effective registration statement under the Securities Act, except (i) to Pubco or a subsidiary thereof, (ii) to non-U.S. persons pursuant to offers and sales that occur solely
outside the United States within the meaning of Regulation S under the Securities Act, or (iii) pursuant to another applicable exemption from the registration requirements of the Securities Act, and in each of clauses (i) and (iii), in
accordance with any applicable securities laws of the states and other jurisdictions of the United States, and that any certificates or book entries representing the Shares shall contain a legend to such effect. Subscriber acknowledges that the
Shares will not be eligible for resale pursuant to Rule 144A promulgated under the Securities Act. Subscriber understands and agrees that as a result of the transfer restrictions described herein, Subscriber may not be able to readily resell the
Shares and may be required to bear the financial risk of an investment in the Shares for an indefinite period of time. Subscriber understands that it has been advised to consult legal counsel prior to making any offer, resale, pledge, or transfer of
any of the Shares. 
 2.1.6 Subscriber understands and agrees that Subscriber is purchasing the Shares directly from Pubco. Subscriber
further acknowledges that there have been no representations, warranties, covenants, or agreements made to Subscriber by the Issuer, Pubco, the Company, the Placement Agents (as defined below) or any of their respective affiliates, officers or

or Pubco or any of their respective affiliates (the “Transaction Parties”) as the Plan’s fiduciary with respect to its decision to acquire and hold the Shares (and acknowledges that the Transaction Parties have not acted as the
Plan’s fiduciary with respect to such decision), and (ii) it has not relied on any investment advice from the Transaction Parties with respect to any decision to acquire, continue to hold, or transfer the Shares.

herein shall independently apply to any Class A Ordinary Shares (i) acquired by Subscriber prior to the date hereof or (ii) acquired by the Subscriber after the date hereof other than pursuant to this Subscription Agreement; provided

a substantial interest (as defined in 31 C.F.R. Part 800.244) will acquire a substantial interest in Pubco as a result of the purchase and sale of Shares hereunder such that a declaration to the Committee on Foreign Investment in the United States

disbursements incurred by the Subscriber, the Company or any other person or entity), whether in contract, tort or otherwise, to the Subscriber, or to any person claiming through the Subscriber, in respect of the Transactions. 

2.1.20 No broker, finder, or other financial consultant has acted on behalf of or at the direction of Subscriber in connection with this

and Pubco, as applicable, hereby represents and warrants to Subscriber and agree with Subscriber, as of the date hereof and as of the Closing, as follows: 

2.2.1 The Issuer has been duly incorporated and is validly existing as a corporation in good standing under the laws of the Cayman Islands,

when issued and delivered to Subscriber against full payment for the Shares in accordance with the terms of this Subscription Agreement and registered with Pubco’s transfer agent, the Shares will be validly issued, fully paid, and non-assessable, and will not have been issued in violation of or subject to any preemptive or similar rights created under Pubco’s governing documents or under the laws of its jurisdiction of incorporation or
organization. 
 2.2.3 This Subscription Agreement has been duly authorized and validly executed and delivered by each of the Issuer and
Pubco, and, assuming that this Subscription Agreement constitutes the valid and binding obligation of Subscriber, is the valid and binding obligation of the Issuer and Pubco and is enforceable against the Issuer and Pubco in accordance with its
terms, except as may be limited or otherwise affected by (i) bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium, or other laws relating to or affecting the rights of creditors generally and (ii) principles of equity,
whether considered at law or equity. 

  
 6 

 2.2.4 The execution, delivery, and performance of this Subscription Agreement (including
compliance by the Issuer and Pubco with all of the provisions hereof), issuance and sale of the Shares, and the consummation of the Transactions, will not (i) conflict with or result in a breach or violation of any of the terms or provisions
of, or constitute a default under, or result in the creation or imposition of any lien, charge, or encumbrance upon any of the property or assets of the Issuer, Pubco or any of their respective subsidiaries pursuant to the terms of any indenture,
mortgage, deed of trust, loan agreement, lease, license, or other agreement or instrument to which the Issuer, Pubco or any of their respective subsidiaries is a party or by which the Issuer, Pubco or any of their respective subsidiaries is bound or
to which any of the property or assets of the Issuer, Pubco or any of their respective subsidiaries is subject, which would reasonably be expected to have a material adverse effect on the business, financial condition or results of operations of the
Issuer, Pubco or and any of their respective subsidiaries, taken as a whole, or the ability of the Issuer or Pubco to enter into and timely perform its obligations under this Subscription Agreement (an “Issuer Material Adverse
Effect”), (ii) result in any violation of the provisions of the organizational documents of the Issuer, Pubco or any of their respective subsidiaries, or (iii) result in any violation of any statute or any judgment, order, rule, or
regulation of any court or governmental agency or body, domestic or foreign, having jurisdiction over the Issuer, Pubco or any of their respective subsidiaries or any of its and their respective properties that would, individually or in the
aggregate, reasonably be expected to have an Issuer Material Adverse Effect. 
 2.2.5 Neither the Issuer nor Pubco is required to obtain any
consent, waiver, authorization or order of, give any notice to, or make any filing or registration with, any court or other federal, state, local or other governmental authority or self-regulatory organization in connection with the execution,
delivery and performance of this Subscription Agreement (including, without limitation, the issuance of the Shares), the failure of which would reasonably be expected to have an Issuer Material Adverse Effect, other than (i) filings with the
Securities and Exchange Commission (the “Commission”), (ii) filings required by applicable state securities laws, (iii) any filings required under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 or similar antitrust

with such Other Subscriber’s or investor’s direct or indirect investment in the Pubco or the Issuer in connection with the Transactions (other than any side letter or similar agreement relating to the transfer to any investor of
(i) securities of the Issuer by existing securityholders of the Issuer, which may be effectuated as a forfeiture to the Issuer and reissuance, or (ii) securities to be issued to the direct or indirect securityholders of the Company
pursuant to the Merger Agreement). No Other Subscription Agreement includes terms and conditions that are materially more advantageous to any such Other Subscriber or investor than the Subscriber hereunder as set forth in this Subscription
Agreement. The Other Subscription Agreements have not been amended in any material respect following the date of this Subscription Agreement.

the Issuer, threatened against the Issuer by NYSE or the Commission. The Issuer has taken no action that is designed to terminate the registration of the Class A Ordinary Shares under the Exchange Act. As of the Closing Date, the issued and
outstanding Shares are expected to be registered pursuant to Section 12(b) of the Exchange Act and listed for trading on the NYSE.

comment letters from the Commission staff with respect to any of the SEC Documents. 
 2.2.10 As of the date hereof, the authorized capital
stock of the Issuer is 555,000,000 shares, consisting of (a) 500,000,000 shares of Class A Ordinary Shares, (b) 50,000,000 shares of Class B Ordinary Shares, par value $0.0001 per share (the “Class B Ordinary

Class A Ordinary Shares and Class B Ordinary Shares have been duly authorized and validly issued, are fully paid and are non-assessable and are not subject to preemptive rights and
(B) outstanding Private Placement Warrants and Public Warrants have been duly authorized and validly issued, are fully paid and are not subject to preemptive rights. Except as set forth above and pursuant to the Other Subscription Agreements
and the Merger Agreement, there are no outstanding options, warrants or other rights to subscribe for, purchase or acquire from the Issuer any shares of Class A Ordinary Shares or Class B Ordinary Shares, or any other equity interests in
the Issuer, or securities convertible into or exchangeable or exercisable for such equity interests. Other than as set forth in the Merger Agreement, there are no securities or instruments issued by or to which the Issuer is a party containing
anti-dilution or similar provisions that will be triggered and not fully waived by the holder of such securities or instruments pursuant to a written agreement or consent by the issuance of the Shares pursuant to this Subscription Agreement or any
Other Subscription Agreements. 
 2.2.11 As of the date hereof, there are no pending or, to the knowledge of the Issuer, threatened suits,
claim, actions or proceedings (collectively, “Actions”), which, if determined adversely, would, individually or in the aggregate, reasonably be expected to have an Issuer Material Adverse Effect. As of the date hereof, there is no
unsatisfied judgment or any open injunction binding upon the Issuer which would, individually or in the aggregate, reasonably be expected to have an Issuer Material Adverse Effect. 

  
 8 

 2.2.12 Other than the Placement Agents, no broker, finder, or other financial consultant has
acted on behalf of or at the direction of the Issuer in connection with this Subscription Agreement or the transactions contemplated hereby in such a way as to create any liability on Subscriber. Issuer is solely responsible for paying any fees or
any other commission owed to the Placement Agents in connection with the transactions contemplated by this Subscription Agreement. 
 2.2.13
Pubco is not, and immediately after receipt of payment for the Shares, will not be, an “investment company” within the meaning of the Investment Company Act of 1940, as amended. 

2.2.14 Neither the Issuer nor Pubco any person acting on their behalf has engaged or will engage in any form of general solicitation or general
advertising (within the meaning of Regulation D of the Securities Act) in connection with any offer or sale of the Shares. 
 2.2.15 The
Issuer is in compliance with all applicable laws, except where non-compliance would not reasonably be expected to have an Issuer Material Adverse Effect. The Issuer has not received any written communication
from a governmental authority that alleges that the Issuer is not in compliance with or is in default or violation of any applicable law, except where such non-compliance, default or violation would not
reasonably be expected to have individually or in the aggregate an Issuer Material Adverse Effect. 
 2.2.16 The Issuer and Pubco acknowledge
and agree that notwithstanding anything herein to the contrary, the Shares may be pledged by the Subscriber in connection with a bona fide margin agreement, which shall not be deemed to be a transfer, sale or assignment of the Shares hereunder, and
the Subscriber effecting a pledge of Shares shall not be required to provide the Issuer or Pubco with any notice thereof or otherwise make any delivery to the Issuer or Pubco pursuant to this Subscription Agreement; provided that Subscriber and its
pledgee shall be required to comply with the provisions of Section 2.1.5 hereof in order to effect a sale, transfer or assignment of Shares to such pledgee. The Issuer and Pubco hereby agree to execute and deliver such
documentation as a pledgee of the Shares may reasonably request in connection with a pledge of the Shares to such pledgee by the Subscriber. 

3. Settlement Date and Delivery; Closing. 

3.1.1 Subject to the satisfaction or waiver of the conditions set forth in Sections 3.1.1, 3.1.2 and 3.1.3 below, the
closing of the Subscription contemplated hereby (the “Closing”) shall occur on the date of, and substantially concurrently with, the consummation of the First Merger and Second Merger (such date, the “Closing
Date”). Upon written notice from (or on behalf of) the Issuer to Subscriber (the “Closing Notice”) at least five (5) Business Days prior to the date that the Issuer reasonably expects all conditions to the closing of
the Transactions to be satisfied (the “Expected Closing Date”), Subscriber shall deliver to Pubco, no later than immediately prior to the consummation of the First Merger on the Closing Date, (x) the Purchase Price for the
Shares by wire transfer of United States dollars in immediately available funds to the account specified by the Issuer in the Closing Notice and (y) such information as is reasonably requested in the Closing Notice in order for the Issuer to

of United States dollars in immediately available funds to an account specified by Subscriber. Notwithstanding such return, (i) a failure to close on the Expected Closing Date shall not, by itself, be deemed to be a failure of any of the
conditions to Closing set forth in this Section 3 to be satisfied or waived on or prior to the Closing 

  
 9 

 
Date, and (ii) Subscriber shall remain obligated to (a) redeliver funds representing the Purchase Price to Pubco following the Issuer’s delivery to Subscriber of a new Closing

copy of the records of Pubco’s transfer agent showing the Subscriber (or such nominee or custodian, as applicable) as the owner of the Shares on and as of the Closing. For purposes of this Subscription Agreement, “Business Day”

transactions contemplated hereby; 
 (4) no suspension of the qualification of the Shares for offering or sale or trading in
any jurisdiction shall have occurred, and the NYSE shall have conditionally authorized, subject to official notice of issuance, the listing of the Shares; and

 4. Registration Statement. 

4.1 Pubco agrees that, as soon as practicable, but in no event later than fifteen (15) calendar days after the consummation of the
Transactions, Pubco will file with the Commission (at Pubco’s sole cost and expense) a registration statement (the “Registration Statement”) registering the resale of the Shares (the “Registrable Securities”),
and Pubco shall use its commercially reasonable efforts to have the Registration Statement declared effective as soon as practicable after the filing thereof, but no later than the earlier of (i) the 60th calendar day (or 90th calendar day if the Commission notifies Pubco that it will “review” the Registration Statement) following the
Closing Date and (ii) the 10th Business Day after the date Pubco is notified (orally or in writing, whichever is earlier) by the Commission that the Registration Statement will not be
“reviewed” or will not be subject to further review (or, in either case of (i) or (ii) above, if such date falls on a Saturday, Sunday or other day that the Commission is closed for business, the next business day on which the
Commission is open for business); provided, however, that Pubco’s obligations to include the Registrable Securities in the Registration Statement are contingent upon Subscriber furnishing a completed and executed “selling
shareholders questionnaire” in customary form to Pubco that contains the information required by Commission rules for a Registration Statement regarding Subscriber, the securities of Pubco held by Subscriber, and the intended method of
disposition of the Registrable Securities to effect the registration of the Registrable Securities, and Subscriber shall execute and deliver such documents in connection with such registration as Pubco may reasonably request that are customary of a
selling stockholder in similar situations, including providing that Pubco shall be entitled to postpone and suspend the effectiveness or use of the Registration Statement during any customary blackout or similar period or as permitted hereunder;
provided that the Subscriber shall not in connection with the foregoing be required to execute any lock-up or similar agreement or otherwise be subject to any contractual restriction on the ability to
transfer the Shares. In no event shall the Subscriber be identified as a statutory underwriter in the Registration Statement unless requested by the Commission; provided that if the Commission requests that the Subscriber be identified as a
statutory underwriter in the Registration Statement, the Subscriber will have an opportunity to withdraw from the Registration Statement. 

4.2 In the case of the registration effected by Pubco pursuant to this Subscription Agreement, Pubco shall, upon reasonable request, inform
Subscriber as to the status of such registration. At its expense, Pubco shall: 
 4.2.1 except for such times as Pubco is permitted hereunder
to suspend the use of the prospectus forming part of a Registration Statement, use its commercially reasonable efforts to keep such registration, and any qualification, exemption, or compliance under state securities laws which Pubco determines to
obtain, continuously effective with respect to Subscriber, and to keep the applicable Registration Statement or any subsequent shelf registration statement free of any material misstatements or omissions, until the earlier of the following:
(i) Subscriber ceases to hold any Registrable Securities; (ii) the date all Registrable Securities held by Subscriber may be sold without restriction under Rule 144, including without limitation, any volume and manner of sale restrictions
which may be applicable to affiliates under Rule 144 and without the requirement for Pubco to be in compliance with the current public information required under Rule 144(c)(1) (or Rule 144(i)(2), if applicable) and (iii) two years from the
date of the effectiveness of the Registration Statement; 
 4.2.2 advise Subscriber as expeditiously as possible, but in any event within
five (5) Business Days: 
 (a) when a Registration Statement or any post-effective amendment thereto has become
effective; 
 (b) after it shall receive notice or obtain knowledge thereof, of the issuance by the Commission of any stop
order suspending the effectiveness of any Registration Statement or the initiation of any proceedings for such purpose; 

(c) of the receipt by Pubco of any notification with respect to the suspension of the qualification of the Registrable
Securities included therein for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and 

  
 12 

 (d) subject to the provisions in this Subscription Agreement, of the
occurrence of any event that requires the making of any changes in any Registration Statement or prospectus so that, as of such date, the statements therein are not misleading and do not omit to state a material fact required to be stated therein or
necessary to make the statements therein (in the case of a prospectus, in the light of the circumstances under which they were made) not misleading. 

Notwithstanding anything to the contrary set forth herein, Pubco shall not, when so advising Subscriber of such events, provide
Subscriber with any material, nonpublic information regarding Pubco other than to the extent that providing notice to Subscriber of the occurrence of the events listed in (a) through (d) above may constitute material, nonpublic information
regarding Pubco; 
 4.2.3 use its commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of any
Registration Statement as soon as reasonably practicable; 
 4.2.4 upon the occurrence of any event contemplated in
Section 4.2.2(d), except for such times as Pubco is permitted hereunder to suspend, and has suspended, the use of a prospectus forming part of a Registration Statement, Pubco shall use its commercially reasonable efforts to
as soon as reasonably practicable prepare a post-effective amendment to such Registration Statement or a supplement to the related prospectus, or file any other required document, so that, as thereafter delivered to purchasers of the Registrable
Securities included therein, such prospectus will not include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not
misleading; 
 4.2.5 use its commercially reasonable efforts to cause all Shares to be listed on each securities exchange or market, if any,
on which Pubco’s Shares are then listed; and 
 4.2.6 use its commercially reasonable efforts to take all other steps necessary to
effect the registration of the Shares contemplated hereby. 
 4.3 Notwithstanding anything to the contrary in this Subscription Agreement, if
the Commission prevents Pubco from including in the Registration Statement any or all of the Shares due to limitations on the use of Rule 415 of the Securities Act for the resale of the Shares by the Subscriber, the Registration Statement shall
register for resale such number of Shares which is equal to the maximum number of Shares as is permitted by the Commission. In such event, the number of Shares to be registered for each selling shareholder named in the Registration Statement shall
be reduced pro rata among all such selling shareholders. 
 4.4 Notwithstanding anything to the contrary in this Subscription Agreement,
Pubco shall be entitled to delay or postpone the effectiveness of the Registration Statement, and from time to time to require Subscriber not to sell under the Registration Statement or to suspend the effectiveness thereof, if it determines that in
order for the Registration Statement not to contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements contained therein not misleading, (i) an amendment thereto would be needed to include
information that would at that time not otherwise be required in a current, quarterly, or annual report under the Exchange Act or (ii) the negotiation or consummation of a transaction Pubco or its subsidiaries is pending or an event has
occurred, which negotiation, consummation or event Pubco’s board of directors reasonably believes would require 

  
 13 

 
additional disclosure by Pubco in the Registration Statement of material information that Pubco has a bona fide business purpose for keeping confidential and the non-disclosure of which in the Registration Statement would be expected, in the reasonable determination of Pubco’s board of directors to cause the Registration Statement to fail to comply with applicable
disclosure requirements, (each such circumstance, a “Suspension Event”); provided, however, that Pubco may not delay or suspend the Registration Statement on more than three (3) occasions or for 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; and, provided further, that Pubco shall use commercially reasonable efforts to
make the Registration Statement available for sale by the Subscriber of its Shares as soon as practicable following any such suspension. Upon receipt of any written notice from Pubco of the happening of any Suspension Event during the period that
the Registration Statement is effective or if as a result of a Suspension Event the Registration Statement or related prospectus contains any untrue statement of a material fact or omits to state any material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under which they were made (in the case of the prospectus) not misleading, Subscriber agrees that (a) it will immediately discontinue offers and sales of the Shares under
the Registration Statement until Subscriber receives copies of a supplemental or amended prospectus (which Pubco agrees to promptly prepare) that corrects the misstatement(s) or omission(s) referred to above and receives notice that any
post-effective amendment has become effective or unless otherwise notified by Pubco that it may resume such offers and sales, and (b) it will maintain the confidentiality of any information included in such written notice delivered by Pubco. If
so directed by Pubco, Subscriber will deliver to Pubco or, in Subscriber’s sole discretion destroy, all copies of the prospectus covering the Shares in Subscriber’s possession and will confirm in writing (including by email) such return or
destruction; provided, however, that this obligation to deliver or destroy all copies of the prospectus covering the Shares shall not apply (1) to the extent Subscriber is required to retain a copy of such prospectus (A) in
order to comply with applicable legal, regulatory, self-regulatory, or professional requirements, or (B) in accordance with a bona fide pre-existing document retention policy, or (2) to copies stored
electronically on archival servers as a result of automatic data back-up (provided that such archival copies are not accessed). 

4.5 Indemnification. 
 4.5.1 Pubco
agrees to indemnify, to the extent permitted by law, the Subscriber (to the extent a seller under the Registration Statement), its directors, officers, employees, advisors and agents, and each person who controls the Subscriber (within the meaning
of the Securities Act), to the extent permitted by law, against all losses, claims, damages, liabilities and reasonable and documented out of pocket expenses (including reasonable and documented attorneys’ fees) caused by any untrue statement
of material fact contained in any Registration Statement, prospectus included in any Registration Statement (“Prospectus”) or preliminary Prospectus or any amendment thereof or supplement thereto or any omission of a material fact
required to be stated therein or necessary to make the statements therein (in the case of a Prospectus, in the light of the circumstances under which they were made) not misleading, except insofar as the same are caused by or contained in any
information or affidavit so furnished in writing to Pubco by or on behalf of the Subscriber expressly for use therein. 
 4.5.2 To the extent
permitted by law, Subscriber shall, severally and not jointly with any Other Subscriber or selling stockholder under the Registration Statement, indemnify Pubco, its directors and officers and each person or entity who controls Pubco (within the
meaning of the Securities Act) against any losses, claims, damages, liabilities and expenses (including, without limitation, reasonable and documented outside attorneys’ fees) resulting from any untrue statement of material fact contained or
incorporated by reference in any Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission of a material fact required to be stated therein or necessary to make the statements therein
(in the case of a Prospectus, in the light of the circumstances under which they were made) not misleading, but only to the extent that such untrue statement or omission is contained (or not contained in, in the case of an omission) in any
information or affidavit so furnished in writing by on behalf of the Subscriber expressly for use therein; provided, however, that the liability of the Subscriber shall be limited to the net proceeds received by the Subscriber from the sale of
Registrable Securities giving rise to such indemnification obligation. 

  
 14 

 4.5.3 Any person or entity entitled to indemnification herein shall (a) 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 or entity’s right to indemnification hereunder to the
extent such failure has not prejudiced or damaged the indemnifying party) and (b) 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, conditioned or delayed). An indemnifying party who 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 outside legal counsel
to 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 (which consent
shall not be reasonably withheld, conditioned or delayed), 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.

 4.5.4 The indemnification provided for under this Subscription 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, advisor, agent or controlling person or entity of such indemnified party and shall survive the transfer of securities. 

4.5.5 If the indemnification provided under this Section 4.5 from the indemnifying party is unavailable or insufficient to hold harmless
an indemnified party in respect of any losses, claims, damages, liabilities and 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 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 statement of a material fact or omission to state a
material fact, was made by (or not made by, in the case of an omission), or relates to information supplied by (or not supplied by, in the case of an omission), 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. 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 this Section 4.5, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding. 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 4.5.5 from any person or entity who was not guilty of such fraudulent misrepresentation. Each
indemnifying party’s obligation to make a contribution pursuant to this Section 4.5.5 shall be individual, not joint and several, and in no event shall the liability of the Subscriber exceed the net proceeds received by such Subscriber
from the sale of Registrable Securities giving rise to such indemnification obligation. 

  
 15 

 4.6 Subject to receipt from the Subscriber by Pubco and its transfer agent of customary
representations and other documentation reasonably acceptable to Pubco and its transfer agent in connection therewith, including, if required by the transfer agent, an opinion of Pubco’s and/or the Subscriber’s counsel, in a form
reasonably acceptable to the transfer agent, to the effect that the removal of such restrictive legends in such circumstances may be effected under the Securities Act, the Subscriber may request that Pubco remove any legend from the book entry
position evidencing the Shares within five (5) Business Days of request, following the earliest of such time as the Shares (A) are subject to or have been or are about to be sold or transferred pursuant to an effective registration
statement or (B) have been or are about to be sold pursuant to Rule 144. With respect to clause (A), while the Registration Statement is effective, Pubco shall use commercially reasonable efforts cause its counsel, or counsel acceptable to the
transfer agent, to issue to the transfer agent a “blanket” legal opinion to allow the legend on the Shares to be removed upon resale of the Shares pursuant to the effective Registration Statement in accordance with this Section 4.5.6,
to the extent requested by the transfer agent to effectuate the removal of the legend in connection with such sales. If restrictive legends are no longer required for the Shares pursuant to the foregoing, Pubco shall, in accordance with the
provisions of this section and reasonably promptly following any request therefor from the Subscriber accompanied by such customary and reasonably acceptable representations and other documentation referred to above establishing that restrictive
legends are no longer required, deliver to the transfer agent irrevocable instructions that the transfer agent shall make a new, unlegended entry for the Shares. Pubco shall be responsible for the fees of the transfer agent associated with such
issuance. 
 5. Termination. This Subscription Agreement shall terminate and be void and of no further force and effect, and all
rights and obligations of the parties hereunder shall terminate without any further liability on the part of any party in respect thereof, upon the earlier to occur of (i) three (3) Business Days after the Merger Agreement is validly terminated
in accordance with its terms, (ii) upon the mutual written agreement of each of the parties hereto to terminate this Subscription Agreement or (iii) on or after December 12, 2021 if the Closing has not occurred on or prior to such
date; provided, that nothing herein will relieve any party from liability for any willful breach hereof prior to the time of termination, and each party will be entitled to any remedies at law or in equity to recover losses, liabilities, or
damages arising from such breach. The Issuer shall promptly notify Subscriber of the termination of the Merger Agreement promptly after the termination of such agreement (if applicable) and any monies paid by the Subscriber to Pubco in connection
herewith shall be returned to the Subscriber in accordance with Section 3.1.1. 
 6. Miscellaneous. 

6.1 Further Assurances. At the Closing, the parties hereto shall execute and deliver such additional documents and take such additional
actions as the parties reasonably may deem to be practical and necessary in order to consummate the Subscription as contemplated by this Subscription Agreement. 

6.1.1 Subscriber acknowledges that the Issuer and Pubco will rely on the acknowledgments, understandings, agreements, representations, and
warranties made by Subscriber contained in this Subscription Agreement. Prior to the Closing, Subscriber agrees to promptly notify the Issuer if any of the acknowledgments, understandings, agreements, representations, and warranties of the
Subscriber set forth herein are no longer accurate in all material respects. 
 6.1.2 Each of the Issuer, Pubco and Subscriber is irrevocably
authorized to produce this Subscription Agreement or a copy hereof to any interested party in any administrative or legal proceeding or official inquiry with respect to the matters covered hereby. 

  
 16 

 6.1.3 The Issuer may request from Subscriber such additional information as the Issuer or
Pubco may reasonably deem necessary to evaluate the eligibility of Subscriber to acquire the Shares, and Subscriber shall promptly provide such information as may be reasonably requested to the extent within Subscriber’s possession and control
or otherwise readily available to Subscriber, provided that the Issuer and Pubco agree to keep confidential any such information provided by Subscriber. 

6.1.4 Subscriber shall pay all of its own expenses in connection with this Subscription Agreement and the transactions contemplated herein.

 6.2 Notices. Any notice or communication required or permitted hereunder shall be in writing and either delivered personally,
emailed, sent by overnight mail via a reputable overnight carrier, or sent by certified or registered mail, postage prepaid, and shall be deemed to be given and received (i) when so delivered personally, (ii) when sent, with no “mail
undeliverable” or other rejection notice, if sent by email, or (iii) three (3) Business Days after the date of mailing to the address below or to such other address or addresses as such person may hereafter designate by notice given

 6.3 Entire Agreement. This Subscription Agreement constitutes the entire agreement,
and supersedes all other prior agreements, understandings, representations, and warranties, both written and oral, among the parties, with respect to the subject matter hereof, including any commitment letter entered into relating to the subject
matter hereof. 
 6.4 Modifications; Amendments; Waivers. This Subscription Agreement may not be amended, modified, supplemented, or
waived (i) except by an instrument in writing, signed by Subscriber, Issuer and Pubco and (ii) without the prior written consent of the Company. No failure or delay of either party in exercising any right or remedy hereunder shall operate
as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such right or power, or any course of conduct, preclude any other or further exercise thereto or the
exercise of any other right or power. 
 6.5 Assignment. Neither this Subscription Agreement nor any rights, interests, or obligations
that may accrue to the parties hereunder (including Subscriber’s rights to purchase the Shares) may be transferred or assigned without the prior written consent of each of the Company and the other parties hereto (other than the Shares acquired
hereunder and then only in accordance with this Subscription Agreement). Notwithstanding the foregoing, Subscriber may assign its rights and obligations under this Subscription Agreement to any fund or account managed by the same investment manager
as the Subscriber or by an affiliate of such investment manager without the prior consent of the Issuer; provided further that (x) prior to such assignment, any such assignee shall agree in writing to be bound by the terms hereof and
(y) no such assignment shall relieve the Subscriber of its obligations hereunder. 
 6.6 Benefit. 

6.6.1 Except as otherwise provided herein, this Subscription Agreement shall be binding upon, and inure to the benefit of the parties hereto
and their heirs, executors, administrators, successors, legal representatives, and permitted assigns, and the agreements, representations, warranties, covenants, and acknowledgments contained herein shall be deemed to be made by, and be binding
upon, such heirs, executors, administrators, successors, legal representatives, and permitted assigns. 
 6.6.2 Each of the Issuer, Pubco and
Subscriber further acknowledge and agree that the Placement Agents are third-party beneficiaries of the representations and warranties of the Issuer, Pubco and Subscriber contained in this Subscription Agreement. 

6.7 Governing Law. This Subscription Agreement, and any claim or cause of action hereunder based upon, arising out of or related to this
Subscription Agreement (whether based on law, in equity, in contract, in tort, or any other theory) or the negotiation, execution, performance, or enforcement of this Subscription Agreement, shall be governed by and construed in accordance with the
internal laws of the State of Delaware, including its statute of limitations, without giving effect to principles or rules of conflicts of law, whether of the State of Delaware or any other jurisdiction, to the extent they would require or permit
the application of laws or statute of limitations of any jurisdiction other than the State of Delaware. 
 6.8 Consent to Jurisdiction;
Waiver of Jury Trial. Each of the parties irrevocably consents to the exclusive jurisdiction and venue of the state courts of the State of Delaware, or any federal court sitting in the State of Delaware (collectively, the “Chosen
Courts”), in connection with any matter based upon or arising out of this Subscription Agreement. Each party hereby irrevocably waives, and shall not assert as a defense in any legal dispute, that (i) such person is not personally
subject to the jurisdiction of the Chosen Courts for any reason, (ii) such legal proceeding may not be brought or is not maintainable 

  
 18 

 
in the Chosen Courts, (iii) such person’s property is exempt or immune from execution, (iv) such legal proceeding is brought in an inconvenient forum, or (v) the venue of such
legal proceeding is improper. Each party hereby consents to service of process in any such proceeding in any manner permitted by Delaware law, further consents to service of process by nationally recognized overnight courier service guaranteeing
overnight delivery, or by registered or certified mail, return receipt requested, at its address specified pursuant to Section 6.2, and waives and covenants not to assert or plead any objection which they might otherwise
have to such manner of service of process. Notwithstanding the foregoing in this Section 6.8, a party may commence any action, claim, cause of action, or suit in a court other than the Chosen Courts solely for the purpose
of enforcing an order or judgment issued by the Chosen Courts. TO THE EXTENT NOT PROHIBITED BY APPLICABLE LAW WHICH CANNOT BE WAIVED, EACH OF THE PARTIES IRREVOCABLY WAIVES ANY RIGHT TO TRIAL BY JURY ON ANY CLAIMS OR COUNTERCLAIMS ASSERTED IN ANY
LEGAL DISPUTE RELATING TO OR ARISING UNDER THIS SUBSCRIPTION AGREEMENT WHETHER NOW EXISTING OR HEREAFTER ARISING. IF THE SUBJECT MATTER OF ANY SUCH LEGAL DISPUTE IS ONE IN WHICH THE WAIVER OF JURY TRIAL IS PROHIBITED, NO PARTY SHALL ASSERT IN SUCH
LEGAL DISPUTE A NONCOMPULSORY COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS SUBSCRIPTION AGREEMENT. FURTHERMORE, NO PARTY SHALL SEEK TO CONSOLIDATE ANY SUCH LEGAL DISPUTE WITH A SEPARATE ACTION OR OTHER LEGAL PROCEEDING IN WHICH A JURY TRIAL
CANNOT BE WAIVED. 
 6.9 Severability. If any provision of this Subscription Agreement shall be invalid, illegal, or unenforceable,
the validity, legality, or enforceability of the remaining provisions of this Subscription Agreement shall not in any way be affected or impaired thereby and shall continue in full force and effect. 

6.10 No Waiver of Rights, Powers, and Remedies. No failure or delay by a party hereto in exercising any right, power, or remedy under
this Subscription Agreement, and no course of dealing between the parties hereto, shall operate as a waiver of any such right, power, or remedy of such party. No single or partial exercise of any right, power, or remedy under this Subscription
Agreement by a party hereto, nor any abandonment or discontinuance of steps to enforce any such right, power, or remedy, shall preclude such party from any other or further exercise thereof or the exercise of any other right, power, or remedy
hereunder. The election of any remedy by a party hereto shall not constitute a waiver of the right of such party to pursue other available remedies. No notice to or demand on a party not expressly required under this Subscription Agreement shall
entitle the party receiving such notice or demand to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of the party giving such notice or demand to any other or further action in any
circumstances without such notice or demand. 
 6.11 Remedies. 

6.11.1 The parties agree that each party will suffer irreparable damage if this Subscription Agreement were not performed or the Closing is not
consummated in accordance with its specific terms or this Subscription Agreement was otherwise breached and that money damages or other legal remedies would not be an adequate remedy for any such damage. It is accordingly agreed that the Issuer and
Pubco shall be entitled to equitable relief, including in the form of an injunction or injunctions, to prevent breaches or threatened breaches of this Subscription Agreement and to enforce specifically the terms and provisions of this Subscription
Agreement in an appropriate court of competent jurisdiction as set forth in Section 6.8, this being in addition to any other remedy to which any party is entitled at law or in equity, including money damages. The right to
specific enforcement shall include the right of the Issuer and Pubco to cause the parties hereto to cause the transactions contemplated hereby to be consummated on the terms and subject to the conditions and limitations set forth in this
Subscription Agreement (including, 

  
 19 

 
for the avoidance of doubt, the right to directly enforce each of the covenants and agreements of Subscriber under this Subscription Agreement). The parties hereto further agree (i) to waive
any requirement for the security or posting of any bond in connection with any such equitable remedy, (ii) not to assert that a remedy of specific enforcement pursuant to this Section 6.11 is unenforceable, invalid,
contrary to applicable law, or inequitable for any reason, and (iii) to waive any defenses in any action for specific performance, including the defense that a remedy at law would be adequate. 

6.11.2 The parties acknowledge and agree that this Section 6.11 is an integral part of the transactions contemplated
hereby and without that right, the parties hereto would not have entered into this Subscription Agreement. 
 6.12 Headings and
Captions. The headings and captions of the various subdivisions of this Subscription Agreement are for convenience of reference only and shall in no way modify or affect the meaning or construction of any of the terms or provisions hereof. 

6.13 Counterparts. This Subscription Agreement may be executed in one or more counterparts, all of which when taken together shall be
considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other parties, it being understood that the parties need not sign the same counterpart. In the event that any
signature is delivered by facsimile transmission, email, or any other form of electronic delivery (including .pdf or Docusign), such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is
executed) with the same force and effect as if such signature page were an original thereof. 
 6.14 Construction. The words
“include,” “includes,” and “including” will be deemed to be followed by “without limitation.” Pronouns in masculine, feminine, and neuter genders will be construed to include any
other gender, and words in the singular form will be construed to include the plural and vice versa, unless the context otherwise requires. The words “this Subscription Agreement,” “herein,”
“hereof,” “hereby,” “hereunder,” and words of similar import refer to this Subscription Agreement as a whole and not to any particular subdivision unless expressly so limited. All references in this
Subscription Agreement to numbers of shares, per share amounts, and purchase prices shall be appropriately adjusted to reflect any stock split, stock dividend, stock combination, recapitalization, or the like occurring after the date hereof. 

6.15 Mutual Drafting. This Subscription Agreement is the joint product of the parties hereto and each provision hereof has been subject
to the mutual consultation, negotiation, and agreement of the parties and shall not be construed for or against any party hereto. 
 7.
Cleansing Statement; Disclosure. The Issuer shall, by 9:00 a.m., New York City time, on the first (1st) Business Day immediately following the date of this Subscription Agreement,
issue one (1) or more press releases or file with the Commission a Current Report on Form 8-K (collectively, the “Disclosure Document”) disclosing all material terms of the transactions
contemplated hereby and by the Other Subscription Agreements and the Transactions and any other material, nonpublic information that the Issuer, the Company, any of their respective subsidiaries or any of their respective officers, directors,
employees, affiliates or agents has provided to the Subscriber at any time prior to the filing of such Disclosure Document. As of immediately following the filing of the Disclosure Document, to the Issuer’s knowledge, the Subscriber shall not
be in possession of any material, non-public information received from the Issuer, the Company, any of their respective subsidiaries or any of their respective officers, directors, employees, affiliates or
agents that is not disclosed in the Disclosure Document or in prior filings with the Commission. In addition, effective upon the filing of the Disclosure Document, the Issuer acknowledges and agrees that any and all confidentiality or similar
obligations under any agreement, whether written or oral, in connection with the Transactions between the Issuer or any of its agents, on the one hand, and the 

  
 20 

 
Subscriber or any of its affiliates, on the other hand, shall terminate and be of no further force or effect. Notwithstanding the foregoing, the Issuer shall not and shall direct its directors,
officers, employees, agents and the Company not to publicly disclose the name of Subscriber or any affiliate or investment adviser of Subscriber, or include the name of Subscriber or any affiliate or investment adviser of Subscriber, without the
prior written consent (including by email) of Subscriber (i) in any press release or (ii) in any filing with the Commission or any regulatory agency or trading market, without the prior written consent (including by e-mail) of Subscriber, except in the Registration Statement contemplated by Section 4 of this Subscription Agreement, as required by the federal securities laws, rules or regulations and/or
to the extent such disclosure is required by other laws, rules or regulations, or at the request of the staff of the Commission or any regulatory agency, in which case the Issuer shall provide Subscriber with prior written notice (including by e-mail) of such permitted disclosure, and shall reasonably consult with Subscriber regarding such disclosure. 

8. Trust Account Waiver. Subscriber acknowledges that the Issuer has established a trust account containing the proceeds of its initial
public offering and from certain private placements (collectively, with interest accrued from time to time thereon, the “Trust Account”). For and in consideration of the Issuer’s entering into this Subscription Agreement, and
for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Subscriber agrees that (i) it has no right, title, interest, or claim of any kind in or to any monies held in the Trust Account, and
(ii) it shall have no right of set-off or any right, title, interest, or claim of any kind (“Claim”) to, or to any monies in, the Trust Account, in each case in connection with this
Subscription Agreement, and hereby irrevocably waives any Claim to, or to any monies in, the Trust Account that it may have in connection with this Subscription Agreement; provided, however, that nothing in this
Section 8 shall be deemed to limit Subscriber’s right, title, interest, or claim to the Trust Account by virtue of such Subscriber’s record or beneficial ownership of securities of the Issuer acquired by any means
other than pursuant to this Subscription Agreement, including any redemption right with respect to any such securities of the Issuer. In the event Subscriber has any Claim against the Issuer under this Subscription Agreement, Subscriber shall pursue

agent or employee of any Other Subscriber, and neither Subscriber nor any of its agents or employees shall have any liability to any Other Subscriber (or any other person) relating to or arising from any such information, materials, statements or
opinions. Nothing contained herein or in any Other Subscription Agreement, and no action taken by Subscriber or any Other Subscribers pursuant hereto or thereto, shall be deemed to constitute the Subscriber and Other Subscribers as a partnership, an
