Exhibit 4.22

 

SIDE AGREEMENT

 

Reference
is made to that certain Securities Purchase Agreement dated as of November 9, 2017 among CollPlant Holdings Ltd. (the “Company”),
and Ami Sagi 70291935, an Israeli citizen (“Ami”) (including its successors and assigns), including any Schedules,
Annexes and Exhibits thereto, as may be amended, supplemented or otherwise modified from time to time (“Purchase Agreement”).

 

WHEREAS,
the Company and Ami have entered into the Purchase Agreement in connection with the sale of securities of the Company; and

 

WHEREAS,
Ami or his successors or assigns (the “Holder”) may hold Warrants to purchase Ordinary Shares represented by
American Depositary Shares issued to Holder on the Second Closing as such terms are defined in the Purchase Agreement (the “Warrants”);
and

 

WHEREAS,
the Warrants may be exercisable to an amount of up to 9,300,000 Ordinary Shares (the “Warrant Shares”) represented
by 186,000 American Depositary Shares (“ADSs”), as subject to adjustment as provided in the Warrants (the “Warrant
ADSs”); and

 

WHEREAS,
the Company and the Holder wish to distinguish the “anti-dilution mechanism” detailed in Section 3(b) of the Warrants
into a separate right of Holder, independent from the terms of the Warrants;

 

NOW,
THEREFORE, as set forth in this side agreement (“Side Agreement”) in consideration of the foregoing, the Company
and the Holder (collectively: “Parties”) agree as follows:

 

Section
1. Definitions. Capitalized terms used and not otherwise defined herein shall have the meanings set forth in the Purchase
Agreement and the Warrant, as applicable.

 

     

     

    

 

Section
2. Subsequent Equity Sales. Until the two (2) year anniversary of the First Closing Date, if the Company or any Subsidiary
thereof, as applicable, shall sell or grant any option to purchase, or sell or grant any right to reprice, or otherwise dispose
of or issue (or announce any offer, sale, grant or any option to purchase or other disposition) any ADSs, Ordinary Shares or any
Ordinary Share Equivalents at a price per share or exercise price (whichever is lower) paid for the securities less than the Exercise
Price then in effect (such lower price, the “Base Share Price” and such issuances collectively, a “Dilutive
Issuance”) (it being understood and agreed that if the holder of the Ordinary Shares or ADSs or any Ordinary Share Equivalents
so issued shall at any time, whether by operation of purchase price adjustments, reset provisions, floating conversion, exercise
or exchange prices or otherwise, or due to warrants, options or rights per share which are issued in connection with such issuance,
be entitled to receive Ordinary Shares or ADSs or any Ordinary Share Equivalents at a Base Share Price that is less than the Exercise
Price, such issuance shall be deemed to have occurred for less than the Exercise Price on such date of the Dilutive Issuance at
such effective price), then simultaneously with the consummation of each Dilutive Issuance the Exercise Price shall be reduced
and only reduced to equal the Base Share Price. Such adjustment shall be made whenever such Ordinary Shares or ADSs or any Ordinary
Share Equivalents are issued. Notwithstanding the foregoing, no adjustments shall be made, paid or issued under this Section 2
in respect of an Exempt Issuance. The Company shall notify the Holder, in writing, no later than the Trading Day following the
issuance or deemed issuance of any Ordinary Shares or ADSs or any Ordinary Share Equivalents subject to this Section 2, indicating
therein the applicable issuance price, or applicable reset price, exchange price, conversion price and other pricing terms (such
notice, the “Dilutive Issuance Notice”). For purposes of clarification, whether or not the Company provides
a Dilutive Issuance Notice pursuant to this Section 2, upon the occurrence of any Dilutive Issuance, the Holder is entitled to
receive a number of Warrant ADSs based upon the Base Share Price regardless of whether the Holder accurately refers to the Base
Share Price in the Notice of Exercise. The provisions of this Section 2 shall be effective only on the date immediately following
the date on which the Company becomes a corporation reporting under Chapter E3 of the Israeli Securities Law and the provisions
of this Section 2 shall apply on such day with retroactive effect as of the Original Issue Date.

 

Section
3. Miscellaneous. The provisions of Section 3(a) (Share Dividends and Splits), Section 3(c) (Subsequent
Rights Offerings), Section 3(d) (Fundamental Transaction), Section 3(e) (Calculations), Section
3(f) (Notice to Holder), Section 4 (Transfer of Warrant) and Section 5 (Miscellaneous)
of the Warrants are hereby incorporated by reference, mutatis mutandis.

 

Section
4. Counterparts and Signature. This Side Agreement may be executed in two or more counterparts (including by fax or
electronic scan, such as PDF), each of which shall be deemed to be an original, with the same effect as if the signatures hereto
were upon the same instrument, and shall become effective when one or more counterparts have been signed by each of the Parties
and delivered (including by fax or electronic scan, such as PDF) to the other Party.

WHEREAS, in connection with the Transaction, Subscriber desires to subscribe for and purchase from the Issuer that number of shares of the
Issuer’s Class A common stock, par value $0.0001 per share (the “Class A Shares”), set forth on the signature page hereto (the “Acquired Shares”) for a purchase price of $10.00 per
share, or the aggregate purchase price set forth on the signature page hereto (the “Purchase Price”), and the Issuer desires to issue and sell to Subscriber the Acquired Shares in consideration of the payment of the Purchase Price
by or on behalf of Subscriber to the Issuer on or prior to the Closing (as defined below); and 

 WHEREAS, in connection with the Transaction, certain other “accredited investors” (as
such term is defined in Rule 501 under the Securities Act of 1933, as amended (the “Securities Act”)), have entered into subscription agreements with the Issuer substantially similar to this Subscription Agreement, pursuant to which
such investors have agreed to purchase on the Closing Date [            ] Class A Shares, in the aggregate, at the Purchase Price (the “Other Subscription
Agreements”). 
 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, Subscriber hereby agrees to subscribe for and
purchase, and the Issuer hereby agrees to issue and sell to Subscriber, upon the payment of the Purchase Price, the Acquired Shares (such subscription and issuance, the “Subscription”). 

2.    Closing. 

a.    The closing of the Subscription contemplated hereby (the “Closing”) is contingent upon the
substantially concurrent consummation of the Transaction and shall occur immediately prior thereto. Not less than five (5) business days prior to the scheduled closing date of the Transaction (the “Closing Date”), the Issuer
shall provide written notice to Subscriber (the “Closing Notice”) of such Closing Date. On the Closing Date, the Issuer shall deliver to Subscriber (i) the Acquired Shares in certificated or book entry form (at
Subscriber’s election), free and clear of any liens or other restrictions whatsoever (other than those arising under state or federal securities laws), in the name of Subscriber (or its nominee in accordance with its delivery instructions) or
to a custodian designated by Subscriber, as applicable and (ii) a copy of the records of the Issuer’s transfer agent (the “Transfer Agent”) showing Subscriber as the owner of the Acquired Shares on and as of the Closing
Date. Upon confirmation of receipt of the share certificate or records of the Transfer Agent, Subscriber shall deliver to the Issuer on the Closing Date the Purchase Price for the Acquired Shares by wire transfer of U.S. dollars in immediately
available funds to the account specified by the Issuer in the Closing Notice. In the event the Transaction does not occur within one (1) business day of the Closing, the Issuer shall promptly (but not later than two (2) business days
thereafter) return the Purchase Price to Subscriber, and any book entries or share certificates shall be deemed cancelled and any share certificates shall be promptly (but not later than two (2) business days thereafter) returned to the Issuer.

 b.    The Closing shall be subject to the conditions that, on the Closing Date: 

(i)    no suspension of the qualification of the Acquired Shares for offering or sale or trading in any jurisdiction, or
initiation or threatening of any proceedings for any of such purposes, shall have occurred; 

  
 2 

 (ii)    all representations and warranties of the Issuer and Subscriber
contained in this Subscription Agreement shall be true and correct in all material respects as of the Closing Date, and consummation of the Closing shall constitute a reaffirmation by each of the Issuer and Subscriber of each of the representations,
warranties and agreements of each such party contained in this Subscription Agreement as of the Closing Date; 

(iii)    the Issuer shall have performed, satisfied and complied in all material respects with all covenants, agreements
and conditions required by this Subscription Agreement to be performed, satisfied or complied with by it at or prior to the Closing; 

(iv)    no governmental authority shall have enacted, issued, promulgated, enforced or entered any judgment, order, law,
rule or regulation (whether temporary, preliminary or permanent) which is then in effect and has the effect of making consummation of the transactions contemplated hereby illegal or otherwise preventing or prohibiting consummation of the
transactions contemplated hereby, and no governmental authority shall have instituted or threatened in writing a proceeding seeking to impose any such prevention or prohibition; 

(v)    neither the Contribution Agreement nor the Related Transaction Agreements shall have been amended to materially
adversely affect Subscriber; and 
 (vi)    all conditions precedent to the closing of the Transaction, including the
approval of the Issuer’s shareholders, shall have been satisfied or waived (other than those conditions that may only be satisfied at the closing of the Transaction, but subject to satisfaction of such conditions as of the closing of the
Transaction). 
 c.    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. 

3.    Issuer Representations and Warranties. The Issuer represents and warrants that: 

a.    The Issuer has been duly incorporated and is validly existing as a corporation in good standing under the laws of the
State of Delaware, with corporate power and authority to own, lease and operate its properties and conduct its business as presently conducted and to enter into, deliver and perform its obligations under this Subscription Agreement. 

b.    The Acquired Shares have been duly authorized and, when issued and delivered to Subscriber against full payment for
the Acquired Shares in accordance with the terms of this Subscription Agreement and registered with the Transfer Agent, the Acquired 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 the Issuer’s certificate of incorporation and bylaws or under the laws of the State of Delaware. 

c.    This Subscription Agreement has been duly authorized, executed and delivered by the Issuer and is enforceable
against it 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. 

  
 3 

 d.    The execution, delivery and performance of this Subscription Agreement
(including compliance by the Issuer with all of the provisions hereof), issuance and sale of the Acquired Shares and the consummation of the other transactions contemplated herein will not 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 pursuant to the terms of (i) any indenture, mortgage, deed of
trust, loan agreement, lease, license or other agreement or instrument to which the Issuer is a party or by which the Issuer is bound or to which any of the property or assets of the Issuer is subject, which would reasonably be expected to have a
material adverse effect on the business, properties, financial condition, stockholders’ equity or results of operations of the Issuer (a “Material Adverse Effect”) or materially affect the validity of the Acquired Shares or the
legal authority of the Issuer to comply in all material respects with the terms of this Subscription Agreement; (ii) the organizational documents of the Issuer; or (iii) 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 or any of its properties that would reasonably be expected to have a Material Adverse Effect or materially affect the validity of the Acquired Shares or the
legal authority of the Issuer to comply in all material respects with this Subscription Agreement. 
 e.    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 by the issuance of (i) the Acquired Shares or (ii) the shares to be issued pursuant to any Other
Subscription Agreement that have not been or will not be validly waived on or prior to the Closing Date. 
 f.    The
Issuer is not in default or violation (and no event has occurred which, with notice or the lapse of time or both, would constitute a default or violation) of any term, condition or provision of (i) the organizational documents of the Issuer,
(ii) any loan or credit agreement, note, bond, mortgage, indenture, lease or other agreement, permit, franchise or license to which the Issuer is now a party or by which the Issuer’s properties or assets are bound or (iii) 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 or any of its properties, except, in the case of clauses (ii) and (iii), for defaults or violations
that have not had and would not be reasonably likely to have, individually or in the aggregate, a Material Adverse Effect. 

g.    The Issuer is not 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, self-regulatory organization or other person in connection with the execution, delivery and performance by the Issuer of this Subscription
Agreement (including, without limitation, the issuance of the Acquired Shares), other than (i) the filing with the Securities and Exchange Commission (the “Commission”) of the Registration Statement (as defined below), (ii)
filings required by applicable state securities laws, (iii) the filing of a Notice of Exempt Offering of Securities on Form D with the Commission under Regulation D of the Securities Act, (iv) the filings required in accordance with
Section 8(n) of this Subscription Agreement; (v) those required by the New York Stock Exchange (the “NYSE”), including with respect to obtaining stockholder approval, and (vi) the failure of which
to obtain would not be reasonably likely to have, individually or in the aggregate, a Material Adverse Effect. 

  
 4 

 h.    The authorized capital stock of the Issuer consists of (i) 1,000,000
shares of preferred stock, par value $0.0001 per share (“Preferred Stock”), (ii) 200,000,000 Class A Shares and (iii) 20,000,000 shares of Class F common stock, par value $0.0001 per share
(“Class F Shares”). As of the date hereof: (i) no shares of Preferred Stock are issued and outstanding, (ii) 65,000,000 Class A Shares are issued and outstanding, (iii) 16,250,000 Class F Shares are
issued and outstanding and (iv) 21,666,666.6667 redeemable purchase warrants and 10,000,000 private placement warrants are outstanding. 

i.    The Issuer has not received any written communication since December 31, 2017, from a governmental entity 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, individually or in the aggregate, be
reasonably likely to have a Material Adverse Effect. 
 j.    The issued and outstanding Class A Shares are
registered pursuant to Section 12(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and are listed for trading on the NYSE under the symbol “TPGE”. There is no suit, action, proceeding or
investigation pending or, to the knowledge of the Issuer, threatened against the Issuer by the NYSE or the Commission with respect to any intention by such entity to deregister the Class A Shares or prohibit or terminate the listing of the
Class A Shares on the NYSE. The Issuer has taken no action that is designed to terminate the registration of the Class A Shares under the Exchange Act. 

k.    Assuming the accuracy of Subscriber’s representations and warranties set forth in
Section 4 of this Subscription Agreement, no registration under the Securities Act is required for the offer and sale of the Acquired Shares by the Issuer to Subscriber. 

l.    Neither the Issuer nor any person acting on its 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 Acquired Shares. 

m.    The Issuer has not entered into any side letter or similar agreement with any investor in connection with such
investor’s direct or indirect investment in the Issuer other than (i) the Contribution Agreement and the Related Transaction Agreements and (ii) the Other Subscription Agreements relating to the issuance and sale by the Issuer of
Class A Shares at the Purchase Price. 
 n.    The Issuer has made available to Subscriber (including via the
Commission’s EDGAR system) a copy of each form, report, statement, schedule, prospectus, proxy, registration statement and other document, if any, filed by the Issuer with the Commission since its initial registration of the Class A Shares
(the “SEC Documents”). None of the SEC Documents filed under the Exchange Act contained, when filed or, if amended, as of the date of such amendment with respect to those disclosures that are amended, any untrue statement of a
material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; provided, that the Issuer makes no such
representation or warranty with respect to the proxy statement to be filed by the Issuer with respect to the Transaction or any other 

  
 5 

 
information relating to EnerVest, Ltd. or any of its affiliates included in any SEC Document or filed as an exhibit thereto. The Issuer has timely filed each report, statement, schedule,
prospectus, and registration statement that the Issuer was required to file with the Commission since its inception. There are no material outstanding or unresolved comments in comment letters from the Commission Staff with respect to any of the SEC
Documents. 
 o.    Except for such matters as have not had and would not be reasonably likely to have, individually or
in the aggregate, a Material Adverse Effect, there is no (i) Proceeding (as defined in the Contribution Agreement) pending, or, to the knowledge of the Issuer, threatened against the Issuer or (ii) judgment, decree, injunction, ruling or
order of any governmental entity or arbitrator outstanding against the Issuer.

not obligated to pay, any brokerage, finder’s or other fee or commission in connection with its issuance and sale of the Acquired Shares, including, for the avoidance of doubt, any fee or commission payable to any stockholder or affiliate of
the Issuer. 
 4.    Subscriber Representations and Warranties. Subscriber represents and warrants that:

Agreement 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. 
 c.    The
execution, delivery and performance by Subscriber of this Subscription Agreement and the consummation of the transactions contemplated herein will not 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 Subscriber or any of its subsidiaries pursuant to the terms of (i) any indenture, mortgage, deed of
trust, loan agreement, lease, license or other agreement or instrument to which Subscriber or any of its subsidiaries is a party or by which Subscriber or any of its subsidiaries is bound or to which any of the property or assets of Subscriber or
any of its subsidiaries is subject, which would reasonably be expected to have a material adverse effect on the business, properties, financial condition, stockholders’ equity or results of operations of Subscriber and any of its subsidiaries,
taken as a whole (a “Subscriber Material Adverse Effect”), or materially affect the legal authority of Subscriber to comply in all material respects with the terms of this Subscription Agreement; (ii) the organizational
documents of Subscriber; or (iii) 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 subsidiaries or any of their respective
properties that would reasonably be expected to have a Subscriber Material Adverse Effect or materially affect the legal authority of Subscriber to comply in all material respects with this Subscription Agreement. 

  
 6 

 d.    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) under the Securities Act) satisfying the applicable requirements set forth on Schedule A, (ii) is
acquiring the Acquired Shares only for its own account and not for the account of others, or if Subscriber is subscribing for the Acquired 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 and agreements herein on behalf of each owner of each such account,
and (iii) is not acquiring the Acquired 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 A following the
signature page hereto). Subscriber is not an entity formed for the specific purpose of acquiring the Acquired Shares. 

e.    Subscriber understands that the Acquired Shares are being offered in a transaction not involving any public offering
within the meaning of the Securities Act and that the Acquired Shares have not been registered under the Securities Act. Subscriber understands that the Acquired 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 the Issuer or a subsidiary thereof, (ii) to non-U.S. persons pursuant to offers and sales that occur outside the
United States within the meaning of Regulation S under the Securities Act, (iii) pursuant to Rule 144 under the Securities Act, provided that all of the applicable conditions thereof have been met or (iv) pursuant to another applicable
exemption from the registration requirements of the Securities Act, and that any certificates or book-entry records representing the Acquired Shares shall contain a legend to such effect. Subscriber acknowledges that the Acquired Shares will not be
eligible for resale pursuant to Rule 144A promulgated under the Securities Act. Subscriber understands and agrees that the Acquired Shares will be subject to transfer restrictions and, as a result of these transfer restrictions, Subscriber may not
be able to readily resell the Acquired Shares and may be required to bear the financial risk of an investment in the Acquired 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 Acquired Shares. 
 f.    Subscriber understands and agrees
that Subscriber is purchasing the Acquired Shares directly from the Issuer. Subscriber further acknowledges that there have been no representations, warranties, covenants and agreements made to Subscriber by the Issuer or any of its officers or
directors, expressly or by implication, other than those representations, warranties, covenants and agreements included in this Subscription Agreement. 

g.    Subscriber represents and warrants that its acquisition and holding of the Acquired Shares will not constitute or
result in a non-exempt prohibited transaction under section 406 of the Employee Retirement Income Security Act of 1974, as amended, section 4975 of the Internal Revenue Code of 1986, as amended (the
“Code”), or any applicable similar law. 

  
 7 

 h.    In making its decision to purchase the Acquired Shares, Subscriber
represents that it has relied solely upon independent investigation made by Subscriber. Subscriber acknowledges and agrees that Subscriber has received such information as Subscriber deems necessary in order to make an investment decision with
respect to the Acquired Shares, including with respect to the Issuer, the Transaction and the Related Transactions. Subscriber represents and agrees that Subscriber and Subscriber’s professional advisor(s), if any, have had the full opportunity
to ask such questions, receive such answers and obtain such information as Subscriber and such Subscriber’s professional advisor(s), if any, have deemed necessary to make an investment decision with respect to the Acquired Shares. 

i.    Subscriber became aware of this offering of the Acquired Shares solely by means of direct contact between Subscriber
and the Issuer, and the Acquired Shares were offered to Subscriber solely by direct contact between Subscriber and the Issuer. Subscriber did not become aware of this offering of the Acquired Shares, nor were the Acquired Shares offered to
Subscriber, by any other means. Subscriber acknowledges that the Issuer represents and warrants that the Acquired Shares (i) were not offered by any form of general solicitation or general advertising and (ii) are not being offered in a
manner involving a public offering under, or in a distribution in violation of, the Securities Act, or any state securities laws. 

j.    Subscriber acknowledges that it is aware that there are substantial risks incident to the purchase and ownership of
the Acquired Shares. Subscriber has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of an investment in the Acquired Shares, and Subscriber has sought such accounting, legal and tax
advice as Subscriber has considered necessary to make an informed investment decision. 
 k.    Alone, or together with
any professional advisor(s), Subscriber represents and acknowledges that Subscriber has adequately analyzed and fully considered the risks of an investment in the Acquired Shares and determined that the Acquired Shares are a suitable investment for
Subscriber and that Subscriber is able at this time and in the foreseeable future to bear the economic risk of a total loss of Subscriber’s investment in the Issuer. Subscriber acknowledges specifically that a possibility of total loss exists.

 l.    Subscriber understands and agrees that no federal or state agency has passed upon or endorsed the merits of the
offering of the Acquired Shares or made any findings or determination as to the fairness of this investment. 

m.    Subscriber represents and warrants that Subscriber is not (i) a person or entity named on the List of Specially
Designated Nationals and Blocked Persons, the Executive Order 13599 List, the Foreign Sanctions Evaders List, or the Sectoral Sanctions Identification List, each of which is administered by the U.S. Treasury Department’s Office of Foreign
Assets Control (“OFAC”) (collectively “OFAC Lists”), (ii) owned or controlled by, or acting on behalf of, a person, that is named on an OFAC List; (iii) organized, incorporated, established, located, resident
or born in, or a citizen, national, or the government, including any political subdivision, agency, or instrumentality thereof, of, Cuba, Iran, North Korea, Syria, the Crimea region of Ukraine, or any other country or territory embargoed or subject
to substantial trade restrictions by the United States, (iv) a Designated National as defined in the Cuban Assets Control Regulations, 31 C.F.R. Part 515, or (v) a non-U.S. shell bank or providing
banking services indirectly to a non-U.S. shell bank (collectively, a “Prohibited Investor”). Subscriber represents

that if it is a financial institution subject to the Bank Secrecy Act (31 U.S.C. section 5311 et seq.) (the “BSA”), as amended by the USA PATRIOT Act of 2001 (the
“PATRIOT Act”), and its implementing regulations (collectively, the “BSA/PATRIOT Act”), that Subscriber maintains policies and procedures reasonably designed to comply with applicable obligations under the
BSA/PATRIOT Act. Subscriber also represents that, to the extent required, it maintains policies and procedures reasonably designed to ensure compliance with OFAC-administered sanctions programs, including for the screening of its investors against
the OFAC Lists. Subscriber further represents and warrants that, to the extent required, it maintains policies and procedures reasonably designed to ensure that the funds held by Subscriber and used to purchase the Acquired Shares were legally
derived. 
 n.    If Subscriber is an employee benefit plan that is subject to Title I of the Employee Retirement Income
Security Act of 1974, as amended (“ERISA”), a plan, an individual retirement account or other arrangement that is subject to section 4975 of the Code or an employee benefit plan that is a governmental plan (as defined in section
3(32) of ERISA), a church plan (as defined in section 3(33) of ERISA), a non-U.S. plan (as described in section 4(b)(4) of ERISA) or other plan that is not subject to the foregoing but may be subject to
provisions under any other federal, state, local, non-U.S. or other laws or regulations that are similar to such provisions of ERISA or the Code (collectively, “Similar Laws”), or an entity
whose underlying assets are considered to include “plan assets” of any such plan, account or arrangement (each, a “Plan”) subject to the fiduciary or prohibited transaction provisions of ERISA or section 4975 of the Code,
Subscriber represents and warrants that (i) neither Issuer, nor any of its respective affiliates (the ”Transaction Parties”) has acted as the Plan’s fiduciary, or has been relied on for advice, with respect to its
decision to acquire and hold the Acquired Shares, and none of the Transaction Parties shall at any time be relied upon as the Plan’s fiduciary with respect to any decision to acquire, continue to hold or transfer the Acquired Shares;
(ii) the decision to invest in the Acquired Shares has been made at the recommendation or direction of an “independent fiduciary” (“Independent Fiduciary”) within the meaning of US Code of Federal Regulations 29
C.F.R. section 2510.3 21(c), as amended from time to time (the “Fiduciary Rule”) who is (A) independent of the Transaction Parties; (B) is capable of evaluating investment risks independently, both in general and with
respect to particular transactions and investment strategies (within the meaning of the Fiduciary Rule); (C) is a fiduciary (under ERISA and/or section 4975 of the Code) with respect to Subscriber’s investment in the Acquired Shares and is
responsible for exercising independent judgment in evaluating the investment in the Acquired Shares; and (D) is aware of and acknowledges that (I) none of the Transaction Parties is undertaking to provide impartial investment advice, or to
give advice in a fiduciary capacity, in connection with the purchaser’s or transferee’s investment in the Acquired Shares, and (II) the Transaction Parties have a financial interest in the purchaser’s investment in the Acquired
Shares on account of the fees and other remuneration they expect to receive in connection with transactions contemplated hereunder. 

o.    Subscriber has, and at the Closing will have, sufficient funds to pay the Purchase Price pursuant to
Section 2(a).

 5.    Registration Rights. 

a.    The Issuer agrees that, within thirty (30) calendar days after the consummation of the Transaction (the
“Filing Date”), the Issuer will file with the Commission (at the Issuer’s sole cost and expense) a registration statement registering the resale of the Acquired Shares (the “Registration Statement”), and the
Issuer 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 90th calendar day (or 120th calendar day if the
Commission notifies the Issuer that it will “review” the Registration Statement) following the Closing and (ii) the 10th business day after the date the Issuer 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 (such earlier date, the “Effectiveness Date”); provided, however, that the Issuer’s obligations to include the
Acquired Shares in the Registration Statement are contingent upon Subscriber furnishing in writing to the Issuer such information regarding Subscriber, the securities of the Issuer held by Subscriber and the intended method of disposition of the
Acquired Shares as shall be reasonably requested by the Issuer to effect the registration of the Acquired Shares, and Subscriber shall execute such documents in connection with such registration as the Issuer may reasonably request that are
customary of a selling stockholder in similar situations, including providing that the Issuer 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. For purposes of clarification, any failure by the Issuer to file the Registration Statement by the Filing Date or to effect such Registration Statement by the Effectiveness Date shall not otherwise relieve the Issuer of its
obligations to file or effect the Registration Statement as set forth above in this Section 5. 

b.    The Issuer further agrees that, in the event that (i) the Registration Statement has not been declared
effective by the Commission by the Effectiveness Date, (ii) after such Registration Statement is declared effective by the Commission, (A) such Registration Statement ceases for any reason (including by reason of a stop order, or the
Issuer’s failure to update the Registration Statement), to remain continuously effective as to all Acquired Shares for which it is required to be effective or (B) Subscriber is not permitted to utilize the Registration Statement to resell
the Acquired Shares (in each case of (A) and (B), (x) other than within the time period(s) permitted by this Subscription Agreement and (y) excluding by reason of a post-effective amendment required in connection with the Issuer’s
filing of an amendment thereto (a “Special Grace Period”) (which Special Grace Period shall not be treated as a Registration Default (as defined below)), or (iii) after the date six months following the Closing Date, and only
in the event the Registration Statement is not effective or available to sell all Acquired Shares, the Issuer fails to file with the Commission any required reports under Section 13 or 15(d) of the Exchange Act such that it is not in compliance
with Rule 144(c)(1) (or Rule 144(i)(2), if applicable), as a result of which Subscribers who are not affiliates of the Issuer are unable to sell the Acquired Shares without restriction under Rule 144 (or any successor thereto) (each such event
referred to in clauses (i) through (iii), a “Registration Default” and, for purposes of such clauses, the date on which such Registration Default occurs, a “Default Date”), then in addition to any other rights
Subscriber may have hereunder or under applicable law, on each such Default Date and on each monthly anniversary of each such Default Date (if the applicable Registration Default shall not have been cured by such date) until the applicable
Registration Default is cured, the Issuer shall pay to each Subscriber an amount in cash, as partial liquidated damages and not as a penalty (“Liquidated Damages”), equal to 0.5% of the aggregate Purchase Price paid by Subscriber
pursuant to this Subscription Agreement for any Acquired Shares held 

  
 10 

 
by Subscriber on the Default Date; provided, however, that if Subscriber fails to provide the Issuer with any information requested by the Issuer that is required to be provided in such
Registration Statement with respect to Subscriber as set forth herein, then, for purposes of this Section 5, the Filing Date or Effectiveness Date, as applicable, for a Registration Statement with respect to Subscriber
shall be extended until two (2) business days following the date of receipt by the Issuer of such required information from Subscriber; and in no event shall the Issuer be required hereunder to pay to Subscriber pursuant to this Subscription
Agreement an aggregate amount that exceeds 5.0% of the aggregate Purchase Price paid by Subscriber for its Acquired Shares. The Liquidated Damages pursuant to the terms hereof shall apply on a daily pro-rata
basis for any portion of a month prior to the cure of a Registration Default, except in the case of the first Default Date. The Issuer shall deliver the cash payment to Subscriber with respect to any Liquidated Damages by the fifth business day
after the date payable. If the Issuer fails to pay said cash payment to Subscriber in full by the fifth business day after the date payable, the Issuer will pay interest thereon at a rate of 5.0% per annum (or such lesser maximum amount that is
permitted to be paid by applicable law, and calculated on the basis of a year consisting of 360 days) to such Subscriber, accruing daily from the date such Liquidated Damages are due until such amounts, plus all such interest thereon, are paid in
full. Notwithstanding the foregoing, nothing shall preclude any Subscriber from pursuing or obtaining any available remedies at law, specific performance or other equitable relief with respect to this Section 5 in
accordance with applicable law. The parties agree that notwithstanding anything to the contrary herein, no Liquidated Damages shall be payable to Subscriber with respect to any period during which all of such Subscriber’s Acquired Shares may be
sold by Subscriber without volume or manner of sale restrictions under Rule 144 and the Issuer is in compliance with the current public information requirements under Rule 144(c)(1) (or Rule 144(i)(2), if applicable). 

c.    In the case of the registration, qualification, exemption or compliance effected by the Issuer pursuant to this
Subscription Agreement, the Issuer shall, upon reasonable request, inform Subscriber as to the status of such registration, qualification, exemption and compliance. At its expense the Issuer shall: 

(i)    except for such times as the Issuer 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 the Issuer 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 Acquired Shares
or (ii) the date all Acquired Shares 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 the Issuer to be in compliance with the current public information required under Rule 144(c)(1) (or Rule 144(i)(2), if applicable), and (iii) three years from the Effective Date of the Registration Statement. The period of
time during which the Issuer is required hereunder to keep a Registration Statement effective is referred to herein as the “Registration Period”; 

  
 11 

 (ii)    advise Subscriber within five (5) business days: 

(1)    when a Registration Statement or any amendment thereto has been filed with the Commission and when such
Registration Statement or any post-effective amendment thereto has become effective; 
 (2)    of any request by the
Commission for amendments or supplements to any Registration Statement or the prospectus included therein or for additional information; 

(3)    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; 
 (4)    of the receipt by the Issuer of any notification with
respect to the suspension of the qualification of the Acquired Shares included therein for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and 

(5)    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, the Issuer shall not, when so advising Subscriber of such events, provide Subscriber with any material, nonpublic information regarding the Issuer other than to the extent that providing notice to Subscriber of the
occurrence of the events listed in (1) through (5) above constitutes material, nonpublic information regarding the Issuer; 

(iii)    use its commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of
any Registration Statement as soon as reasonably practicable; 
 (iv)    upon the occurrence of any event contemplated
above, except for such times as the Issuer is permitted hereunder to suspend, and has suspended, the use of a prospectus forming part of a Registration Statement, the Issuer 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 Acquired Shares 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; 

(v)    use its commercially reasonable efforts to cause all Acquired Shares to be listed on each securities exchange or
market, if any, on which the Class A Shares issued by the Issuer have been listed; and 

  
 12 

 (vi)    use its commercially reasonable efforts to take all other steps
necessary to effect the registration of the Acquired Shares contemplated hereby and to enable Subscriber to sell the Acquired Shares under Rule 144. 

d.    Notwithstanding anything to the contrary in this Subscription Agreement, the Issuer 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 the negotiation or consummation of a transaction by the
Issuer or its subsidiaries is pending or an event has occurred, which negotiation, consummation or event the Issuer’s board of directors reasonably believes, upon the advice of legal counsel, would require additional disclosure by the Issuer in
the Registration Statement of material information that the Issuer 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 the Issuer’s board of directors, upon the advice of legal counsel, to cause the Registration Statement to fail to comply with applicable disclosure requirements (each such circumstance, a “Suspension
Event”); provided, however, that the Issuer may not delay or suspend the Registration Statement on more than two occasions or for more than sixty (60) consecutive calendar days, or more than ninety (90) total
calendar days, in each case during any twelve-month period. Upon receipt of any written notice from the Issuer 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 (i) it will immediately discontinue offers and sales of the Acquired Shares under the Registration Statement (excluding, for the avoidance of
doubt, sales conducted pursuant to Rule 144) until Subscriber receives copies of a supplemental or amended prospectus (which the Issuer 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 the Issuer that it may resume such offers and sales, and (ii) it will maintain the confidentiality of any information included in such written notice
delivered by the Issuer unless otherwise required by law or subpoena. If so directed by the Issuer, Subscriber will deliver to the Issuer or, in Subscriber’s sole discretion destroy, all copies of the prospectus covering the Acquired Shares in
Subscriber’s possession; provided, however, that this obligation to deliver or destroy all copies of the prospectus covering the Acquired Shares shall not apply (i) 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 (ii) to
copies stored electronically on archival servers as a result of automatic data back-up. 

e.    Subscriber may deliver written notice (including via email in accordance with
Section 8(l)) (an “Opt-Out Notice”) to the Issuer requesting that Subscriber not receive notices from the Issuer otherwise required by this
Section 5; provided, however, that Subscriber may later revoke any such Opt-Out Notice in writing. Following receipt of an
Opt-Out Notice from Subscriber (unless subsequently revoked), (i) the Issuer shall not deliver any such notices to Subscriber and Subscriber shall no longer be entitled to the rights associated with any such
notice and (ii) each time prior to Subscriber’s intended use of an effective Registration 

  
 13 

 
Statement, Subscriber will notify the Issuer in writing at least two (2) business days in advance of such intended use, and if a notice of a Suspension Event was previously delivered (or
would have been delivered but for the provisions of this Section 5(e)) and the related suspension period remains in effect, the Issuer will so notify Subscriber, within one (1) business day of Subscriber’s
notification to the Issuer, by delivering to Subscriber a copy of such previous notice of Suspension Event, and thereafter will provide Subscriber with the related notice of the conclusion of such Suspension Event immediately upon its availability.

 6.    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 (a) such date and time as the Contribution Agreement and each of the
Related Transaction Agreements is terminated in accordance with its respective terms, (b) upon the mutual written agreement of each of the parties hereto to terminate this Subscription Agreement, (c) if any of the conditions to Closing set
forth in Section 2 of this Subscription Agreement are not satisfied on or prior to the Closing and, as a result thereof, the transactions contemplated by this Subscription Agreement are not consummated at the Closing or
(d) the End Date (as defined in the Contribution Agreement); 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 Contribution Agreement or either of the Related Transaction Agreements promptly
after the termination of such agreement. 
 7.    Trust Account Waiver. Subscriber acknowledges that the Issuer
is a blank check company with the powers and privileges to effect a merger, asset acquisition, reorganization or similar business combination involving the Issuer and one or more businesses or assets. Subscriber further acknowledges that, as
described in the Issuer’s prospectus relating to its initial public offering dated May 4, 2017 (the “Prospectus”), available at www.sec.gov, substantially all of the Issuer’s assets consist of the cash proceeds of the
Issuer’s initial public offering and private placements of its securities, and substantially all of those proceeds have been deposited in a trust account (the “Trust Account”) for the benefit of the Issuer, its public
shareholders and the underwriters of the Issuer’s initial public offering. Except with respect to interest earned on the funds held in the Trust Account that may be released to the Issuer to pay its tax obligations, if any, the cash in the
Trust Account may be disbursed only for the purposes set forth in the Prospectus. For and in consideration of the Issuer entering into this Subscription Agreement, the receipt and sufficiency of which are hereby acknowledged, Subscriber, on behalf
of itself and its representatives, hereby irrevocable waives any and all right, title and interest, or any claim of any kind they have or may have in the future arising out of this Subscription Agreement, in or to any monies held in the Trust
Account, and agrees not to seek recourse against the Trust Account as a result of, or arising out of, this Subscription Agreement. 

8.    Miscellaneous. 

a.    Subscriber acknowledges that the Issuer and others will rely on the acknowledgments, understandings, agreements,
representations and warranties 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 set forth herein
are no longer accurate in all material respects. 

  
 14 

 b.    Each of the Issuer and Subscriber is entitled to rely upon this
Subscription Agreement and 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. 

c.    Neither this Subscription Agreement nor any rights that may accrue to Subscriber hereunder (other than the Acquired
Shares acquired hereunder, if any) may be transferred or assigned. Neither this Subscription Agreement nor any rights that may accrue to the Issuer hereunder may be transferred or assigned. 

d.    All the agreements, representations and warranties made by each party hereto in this Subscription Agreement shall
survive the Closing. 
 e.    The Issuer may request from Subscriber such additional information as the Issuer may deem
necessary to evaluate the eligibility of Subscriber to acquire the Acquired Shares, and Subscriber shall provide such information as may be reasonably requested, to the extent readily available and to the extent consistent with its internal policies
and procedures. 
 f.    This Subscription Agreement may not be modified, waived or terminated except by an instrument
in writing, signed by the party against whom enforcement of such modification, waiver, or termination is sought. 

g.    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. 

h.    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. 

i.    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. 

j.    This Subscription Agreement may be executed in two (2) or more counterparts (including by electronic means),
all of which shall be considered one and the same agreement and shall become effective when signed by each of the parties and delivered to the other parties, it being understood that all parties need not sign the same counterpart. 

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

  
 15 

 l.    Notices. Any notice or communication required or permitted
hereunder shall be in writing and either delivered personally, emailed or telecopied, 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
