AGREEMENT

 

Article
I.

Sale and Purchase

 

Section 1.01       
Securities.

 

(a)              
Subject to the terms and conditions hereof, the Purchaser hereby irrevocably subscribes for and agrees to purchase from
the Company, and the Company agrees to issue and sell to the Purchaser, the number of Subscribed Securities set forth on Schedule
A hereto for the aggregate purchase price set forth on Schedule A hereto (the “Purchase Price”); provided,
however, that the Purchaser’s subscription for and agreement to purchase, and the Company’s agreement to issue
and sell, the Private Placement Warrants included in the Subscribed Securities are subject to the Subscribing Parties’ purchase
of an aggregate of 2,530,000 Units in the IPO (the “IPO Threshold”); and provided further, that if the
actual number of Units offered and sold in the IPO is less than 20,000,000 (without regard to the over-allotment option), then
the IPO Threshold shall be automatically reduced on a pro rata basis, calculated as a fraction, the numerator of which is the number
of Units sold in the IPO (without regard to the over-allotment option) and the denominator is 20,000,000. The Purchaser acknowledges
that the Subscribed Securities, and any securities of the Company that may be distributed to the Purchaser on account of the Subscribed
Securities (collectively, the “Securities”), will be subject to restrictions on transfer as set forth in this
Agreement.

 

(b)              
On the date hereof, (A) the Company shall issue to the Purchaser the number of Founder Shares set forth on Schedule A
hereto, in consideration for the Purchaser’s payment of the portion of the Purchase Price applicable to such Founder Shares,
as set forth on Schedule A hereto, by wire transfer of immediately available funds or other means approved by the Company,
and (B) the Sponsor shall forfeit to the Company for cancellation, for no consideration, and have no further right, title or interest
in, an equal number of Founder Shares. If the IPO Closing has not occurred by March 31, 2019, then the Company will promptly redeem
the Purchaser’s Founder Shares issued pursuant to this Section 1.01(b) for a cash payment equal to the Purchase Price
paid by the Purchaser in respect of such Founder Shares.

 

    	 	2	 

     

    

 

(c)              
The Company shall notify the Purchaser in writing of the anticipated date of the effectiveness of the Registration Statement
(the “Effective Date”) at least three (3) Business Days (as defined below) prior to the Effective Date, and
the Purchaser shall remit the balance of the Purchase Price to the Company’s transfer agent (to be held in escrow pending
the IPO Closing), by wire transfer of immediately available funds or other means approved by the Company, on the date that is one
Business Day prior to the Effective Date, or such other date as the Company and the Purchaser may agree upon in writing. For purposed
of this Agreement, “Business Day” means any day, other than a Saturday or a Sunday, that is neither a legal
holiday nor a day on which banking institutions are generally authorized or required by law or regulation to close in the City
of New York, New York. If the IPO Closing has not occurred by the date that is seven (7) Business Days after the date on which
the Purchaser remitted the balance of its Purchase Price to the Company’s transfer agent, then, unless the Purchaser otherwise
agrees in writing, the Company will promptly cause its transfer agent to return such amounts to the Purchaser.

 

(d)              
On the date of the IPO Closing, and subject to the Subscribing Parties’ purchase of a number of
Units in the IPO equal to or greater than the IPO Threshold, the Company shall issue to the Purchaser the number of Private Placement
Warrants set forth on Schedule A hereto.

 

(e)              
If the Subscribing Parties do not purchase a number of Units in the IPO equal to or greater than the IPO Threshold, then
the Company will promptly (i) redeem the Purchaser’s Founder Shares issued pursuant to this Section 1.01(e) for a
cash payment equal to the Purchase Price paid by the Purchaser in respect of such Founder Shares and (ii) cause its transfer agent
to return to the Purchaser an amount equal to the Purchase Price paid by the Purchaser in respect of the Private Placement Warrants.

 

Section 1.02       
Delivery of Securities.

 

(a)              
The Company shall register the Purchaser as the owner of the Subscribed Securities with the Company’s transfer agent
by book entry on or prior to the date of the IPO Closing (provided that prior to the date of the IPO Closing the Company shall
register the Purchaser as the owner of such securities in the Company’s stock ledger upon issuance thereof).

 

(b)              
Each register and book entry for the Securities shall contain a notation, and each certificate (if any) evidencing the Securities
shall be stamped or otherwise imprinted with a legend, in substantially the following form:

 

“THE SECURITIES REPRESENTED HEREBY
HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR STATE SECURITIES
LAWS AND CANNOT BE OFFERED, SOLD, OR TRANSFERRED IN THE ABSENCE OF REGISTRATION OR EXEMPTION FROM REGISTRATION UNDER THE SECURITIES
ACT AND APPLICABLE STATE SECURITIES LAWS AND REGULATIONS PROMULGATED THEREUNDER. THE SECURITIES REPRESENTED HEREBY HAVE BEEN ACQUIRED
BY THE REGISTERED OWNER HEREOF FOR INVESTMENT AND NOT WITH A VIEW TO OR FOR SALE IN CONNECTION WITH ANY DISTRIBUTION THEREOF IN
VIOLATION OF THE SECURITIES ACT. THE SECURITIES MAY NOT BE SOLD, PLEDGED, TRANSFERRED OR ASSIGNED EXCEPT IN A TRANSACTION WHICH
IS EXEMPT FROM REGISTRATION UNDER THE PROVISIONS OF THE SECURITIES ACT OR ANY APPLICABLE STATE SECURITIES LAWS, OR PURSUANT TO
AN EFFECTIVE REGISTRATION STATEMENT OR IN A TRANSACTION OTHERWISE IN COMPLIANCE WITH APPLICABLE FEDERAL AND STATE SECURITIES LAWS.

 

    	 	3	 

     

    

 

THE SALE, PLEDGE, HYPOTHECATION, OR
TRANSFER OF THE SECURITIES REPRESENTED HEREBY ARE SUBJECT TO THE TERMS AND CONDITIONS OF A CERTAIN SUBSCRIPTION AGREEMENT BY AND
AMONG THE HOLDER AND THE OTHER PARTIES THERETO. COPIES OF SUCH AGREEMENT MAY BE OBTAINED UPON WRITTEN REQUEST TO THE SECRETARY
OF THE COMPANY.”

 

Section 1.03       
Registration Rights. On the Effective Date, the Company shall enter into a Registration Rights Agreement (the “Registration
Rights Agreement”) with the Sponsor and the Subscribing Parties, in substantially the form provided to the Purchaser
prior to the date hereof. The Registration Rights Agreement shall provide the Purchaser with registration rights with respect to
the Subscribed Securities.

 

Article
II.

Potential Forfeiture.

 

So long as the Subscribing Parties have
purchased a number of Units in the IPO equal to or greater than the IPO Threshold, if (a) on the date of the vote by the Company’s
stockholders to approve the Business Combination or (b) on the Business Day immediately prior to the scheduled closing of the Business
Combination (each, a “Determination Date”), the Purchaser beneficially owns or holds, directly or indirectly,
including through any firm commitments to purchase, a number of Public Shares (the lesser number of Public Shares so beneficially
owned by the Purchaser on either Determination Date, the “Determination Date Shares”) that is less than the
Forfeiture Threshold (as defined below), then the Purchaser shall automatically forfeit to the Company for no consideration, and
have no further right, title or interest in, all of such Purchaser’s Founder Shares. For the avoidance of doubt, in calculating
the number of Public Shares (if any) that the Purchaser beneficially owns or holds, directly or indirectly, for purposes of determining
the number of Determination Date Shares, no Public Shares that are beneficially owned by any other Subscribing Party shall be counted
(e.g., no Public Shares shall be double counted among Subscribing Parties). The Purchaser shall take all actions as may be reasonably
necessary to consummate any forfeiture contemplated by this Article 2, including entering into agreements and delivering
certificates and instruments and consents as may be deemed by the Company to be necessary or appropriate (which shall not require
the Purchaser to make any representations other than as to its clear title to the applicable Founder Shares and its power and authorization
to effect the transactions contemplated by the applicable agreement or other instrument), and the Purchaser hereby grants to the
Company and any representative designated by the Company without further action by the Purchaser a limited irrevocable power of
attorney to effect any forfeiture contemplated hereby on behalf of the Purchaser, which power of attorney shall be deemed to be
coupled with an interest.

 

    	 	4	 

     

    

 

As used herein, the “Forfeiture
Threshold” shall initially mean [ ● ]1
shares of Class A Common Stock; provided, that if the actual number of Units offered and sold in the IPO is less
than 20,000,000 (without regard to the over-allotment option), then the Forfeiture Threshold shall be automatically reduced on
a pro rata basis.

applicable securities laws, rules or regulations.

 

Section
3.04        Compliance
with Other Instruments. The execution, delivery and performance by the Purchaser of this Agreement and the consummation

Trust Account.

 

(a)              
The Purchaser hereby acknowledges that it is aware that the Company will establish the Trust Account for the benefit of
its public stockholders upon the IPO Closing. The Purchaser hereby agrees that it has no right, title, interest or claim of any

that it may have now or in the future, except for redemption and liquidation rights, if any, the Purchaser may have in respect
of any Public Shares held by it. In the event the Purchaser has any Claim against the Company under this Agreement, the Purchaser

Shares held by it.

 

Section 5.03

than pledges in the ordinary course of business as part of prime brokerage arrangements), forward sale contracts, options, puts,

officer or employee of the Purchaser, nor any trade name, trademark, trade device, service mark, symbol or any abbreviation, contraction
or simulation thereof owned by the Purchaser or its affiliates or any information relating to the business or operations of the
Purchaser or its affiliates (including, for the avoidance of doubt, any investment vehicles, funds or accounts managed thereby).
Notwithstanding the foregoing, the Company may disclose (a) the Purchaser’s name and information concerning the Purchaser
(i) to the extent required by law, regulation or regulatory request, including in the Registration Statement to the extent required

disclosure of such document in connection with the transactions contemplated by this Agreement with respect to the Purchaser or
any of their respective affiliates, and will not make any such submission, filing or disclosure without including any revisions
reasonably requested by the Purchaser or if the Purchaser has a good faith objection to such submission, filing or disclosure.

Except as otherwise set forth herein, the mechanics and procedures with respect to the rights and obligations under this

Section 6.14       
Severability. The provisions of this Agreement will be deemed severable and the invalidity or unenforceability of
any provision will not affect the validity or enforceability of the other provisions hereof; provided that if any provision of
this Agreement, as applied to any party hereto or to any circumstance, is adjudged by a governmental authority, arbitrator, or
mediator not to be enforceable in accordance with its terms, the parties hereto agree that the governmental authority, arbitrator,
or mediator making such determination will have the power to modify the provision in a manner consistent with its objectives such
that it is enforceable, and/or to delete specific words or phrases, and in its reduced form, such provision will then be enforceable
and will be enforced.

 

Section 6.15

Section 6.16       
Construction. The parties hereto have participated jointly in the negotiation and drafting of this Agreement. If
an ambiguity or question of intent or interpretation arises, this Agreement will be construed as if drafted jointly by the parties

provision of this Agreement. Any reference to any federal, state, local, or foreign law will be deemed also to refer to law as
amended and all rules and regulations promulgated thereunder, unless the context requires otherwise. 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 Agreement,”
“herein,” “hereof,” “hereby,” “hereunder,” and words of similar import refer to
this Agreement as a whole and not to any particular subdivision unless expressly so limited. The parties hereto intend that each
representation, warranty, and covenant contained herein will have independent significance. If any party hereto has breached any
representation, warranty, or covenant contained herein in any respect, the fact that there exists another representation, warranty
or covenant relating to the same subject matter (regardless of the relative levels of specificity) which such party hereto has
not breached will not detract from or mitigate the fact that such party hereto is in breach of the first representation, warranty,
or covenant.

 

Section 6.17       
Waiver. No waiver by any party hereto of any default, misrepresentation, or breach of warranty or covenant hereunder,
whether intentional or not, may be deemed to extend to any prior or subsequent default, misrepresentation, or breach of warranty
or covenant hereunder or affect in any way any rights arising because of any prior or subsequent occurrence.

 

Section 6.18       
Specific Performance. Each party hereto agrees that irreparable damage may occur in the event any provision of this
Agreement was not performed by the other party hereto in accordance with the terms hereof and that the such party shall be entitled
to specific performance of the terms hereof, in addition to any other remedy at law or equity.

Section 6.19       
Confidentiality. Except as may be required by law, regulation or applicable stock exchange listing requirements (but
subject in any case to the provisions of Section 5.04 hereof), unless and until the transactions contemplated hereby and
the terms hereof are publicly announced or otherwise publicly disclosed by the Company, the parties hereto shall keep confidential
and shall not publicly disclose the existence or terms of this Agreement. Notwithstanding the foregoing, the Purchaser shall be
permitted to disclose any information to its affiliates and its and their respective directors, officers, employees, advisors,
director or indirect owners, agents and representatives, in each case so long as such person or entity has been advised of the
confidentiality obligations hereunder; provided that the Purchaser shall be liable for any breach of such confidentiality obligations
by any such person or entity.

a public offering (the “Public Offering”) of the Company’s units (the “Units”), each
Unit consisting of one share of the Company’s Class A common stock, par value $0.0001 per share (a “Share”),

WHEREAS, the Company and the Purchaser desire
to enter into this Amendment to amend the Original Agreement as provided herein.

 

NOW, THEREFORE, in consideration of the
mutual promises contained in this Agreement and other good and valuable consideration, the receipt and sufficiency of which are

Article
I.

AMENDMENT TO ORIGINAL AGREEMENT

 

Section 1.02 of the Original Agreement
shall be amended and restated in its entirety as follows:

  

“Section 1.02 Purchase
and Sale of the Sponsor Warrants.

 

(a) As
payment in full for the 3,333,333 Sponsor Warrants being purchased under this Agreement, Purchaser shall pay $5,000,000 (the “Purchase

maintained by Citibank, N.A., with American Stock Transfer & Trust Company acting as trustee, on the closing date of the Public
Offering or such earlier date as the Company and the Purchaser shall agree.

 

(b) Solely

as the amount of the over-allotment option that is exercised. Simultaneously with such purchase of Option Sponsor Warrants, as
payment in full for the Option Sponsor Warrants being purchased hereunder, and at least one (1) business day prior to the closing
of all or any portion of the over-allotment option, Purchaser shall pay $1.50 per Option Sponsor Warrant, up to an aggregate amount
of $650,000 (in the event the Anchor Investors have collectively purchased at least 2,530,000 Units in the Public Offering) or

wire transfer of immediately available funds or by such other method as may be reasonably acceptable to the Company, to the Trust

with the closing of the Public Offering (the “Initial Closing Date”). The closing of the purchase and sale of
the Option Sponsor Warrants, if applicable, shall take place simultaneously with the closing of all or any portion of the over-allotment
option (such closing date, together with the Initial Closing Date, the “Closing Dates” and each, a “Closing
Date”). The closing of the purchase and sale of each of the Sponsor Warrants, the Additional Sponsor Warrants and the
