any property, real or personal, or any part of the proceeds arising from any sale of any such property, from attachment, levy or

RE:     Securities
Subscription Agreement

 

Gentlemen:

 

This agreement (this
 “Agreement”) is entered into on October 1, 2020 by and between MCF2 Sponsor, LLC a Cayman Islands limited
liability company (the “Subscriber” or “you”), and MCF2 Acquisition Corp, a Cayman Islands
exempted company (the “Company”). Pursuant to the terms hereof, the Company hereby accepts the offer the Subscriber
has made to purchase 11,500,000 Class B ordinary shares, $0.0001 par value per share (the “Shares”), up
to 1,500,000 of which are subject to surrender and cancellation by you if the underwriters of the initial public offering (“IPO”)
of units (“Units”) of the Company do not fully exercise their over-allotment option (the “Over-allotment
Option”). The Company and the Subscriber’s agreements regarding such Shares are as follows:

 

		1.	Purchase of Securities.

 

1.1          Purchase
of Shares. For the sum of $25,000 (the “Purchase Price”), which the Company acknowledges receiving in cash,
the Company hereby issues the Shares to the Subscriber, and the Subscriber hereby subscribes for and purchases the Shares from
the Company, 1,125,000 of which are subject to surrender and cancellation, on the terms and subject to the conditions set forth
in this Agreement. All references in this Agreement to shares of the Company being surrendered and canceled shall take effect as
surrenders and cancellations for no consideration of such shares as a matter of Cayman Islands law.

 

		2.	Representations, Warranties and Agreements.

 

2.1          Subscriber’s
Representations, Warranties and Agreements. To induce the Company to issue the Shares to the Subscriber, the Subscriber hereby
represents and warrants to the Company and agrees with the Company as follows:

 

2.1.1       No Government Recommendation or Approval. The Subscriber understands that no federal or state agency has passed upon
or made any recommendation or endorsement of the offering of the Shares.

 

2.1.2      
No Conflicts. The execution, delivery and performance of this Agreement and the consummation by the Subscriber of
the transactions contemplated hereby do not violate, conflict with or constitute a default under (i) the formation and governing
documents of the Subscriber, (ii) any agreement, indenture or instrument to which the Subscriber is a party or (iii) any
law, statute, rule or regulation to which the Subscriber is subject, or any agreement, order, judgment or decree to which
the Subscriber is subject.

 

    1 

     

    

2.1.3       
Registration and Authority. The Subscriber is a Cayman Islands limited liability company, validly existing and in
good standing under the laws of the Cayman Islands and possesses all requisite power and authority necessary to carry out the transactions
contemplated by this Agreement. Upon execution and delivery by you, this Agreement will be a legal, valid and binding agreement
of Subscriber, enforceable against Subscriber in accordance with its terms, except as such enforceability may be limited by applicable
bankruptcy, insolvency, fraudulent conveyance or similar laws affecting the enforcement of creditors’ rights generally and
subject to general principles of equity (regardless of whether enforcement is sought in a proceeding at law or in equity).

 

2.1.4       
Experience, Financial Capability and Suitability. Subscriber is: (i) sophisticated in financial matters and
is able to evaluate the risks and benefits of the investment in the Shares and (ii) able to bear the economic risk of its
investment in the Shares for an indefinite period of time because the Shares have not been registered under the Securities Act
(as defined below) and therefore cannot be sold unless subsequently registered under the Securities Act or an exemption from such
registration is available. Subscriber is capable of evaluating the merits and risks of its investment in the Company and has the
capacity to protect its own interests. Subscriber must bear the economic risk of this investment until the Shares are sold pursuant
to: (i) an effective registration statement under the Securities Act or (ii) an exemption from registration available
with respect to such sale. Subscriber is able to bear the economic risks of an investment in the Shares and to afford a complete
loss of Subscriber’s investment in the Shares.

 

2.1.5      
Access to Information; Independent Investigation. Prior to the execution of this Agreement, the Subscriber has
had the opportunity to ask questions of and receive answers from representatives of the Company concerning an investment in the
Company, as well as the finances, operations, business and prospects of the Company, and the opportunity to obtain additional information
to verify the accuracy of all information so obtained. In determining whether to make this investment, Subscriber has relied solely
on Subscriber’s own knowledge and understanding of the Company and its business based upon Subscriber’s own due diligence
investigation and the information furnished pursuant to this paragraph. Subscriber understands that no person has been authorized
to give any information or to make any representations which were not furnished pursuant to this Section 2 and Subscriber
has not relied on any other representations or information in making its investment decision, whether written or oral, relating
to the Company, its operations and/or its prospects.

 

2.1.6       
Regulation D Offering. Subscriber represents that it is an “accredited investor” as such term is defined
in Rule 501(a) of Regulation D under the Securities Act of 1933, as amended (the “Securities Act”)
and acknowledges the sale contemplated hereby is being made in reliance on a private placement exemption to “accredited investors”
within the meaning of Section 501(a) of Regulation D under the Securities Act or similar exemptions under federal and
state law.

 

2.1.7       
Investment Purposes. The Subscriber is purchasing the Shares solely for investment purposes, for the Subscriber’s
own account and not for the account or benefit of any other person, and not with a view towards the distribution or dissemination
thereof. The Subscriber did not decide to enter into this Agreement as a result of any general solicitation or general advertising
within the meaning of Rule 502 of Regulation D under the Securities Act.

 

    2 

     

    

 

2.1.8       
Restrictions on Transfer; Shell Company. Subscriber understands the Shares are being offered in a transaction
not involving a public offering within the meaning of the Securities Act. Subscriber understands the Shares will be “restricted
securities” within the meaning of Rule 144(a)(3) under the Securities Act, and Subscriber understands that the
certificates representing the Shares will contain a legend in respect of such restrictions. If in the future the Subscriber decides
to offer, resell, pledge or otherwise transfer the Shares, such Shares may be offered, resold, pledged or otherwise transferred
only pursuant to: (i) registration under the Securities Act, or (ii) an available exemption from registration. Subscriber
agrees that if any transfer of its Shares or any interest therein is proposed to be made, as a condition precedent to any such
transfer, Subscriber may be required to deliver to the Company an opinion of counsel satisfactory to the Company. Absent registration
or an exemption, the Subscriber agrees not to resell the Shares. Subscriber further acknowledges that because the Company is a
shell company, Rule 144 may not be available to the Subscriber for the resale of the Shares until one year following consummation
of the initial business combination of the Company, despite technical compliance with the requirements of Rule 144 and the
release or waiver of any contractual transfer restrictions.

 

2.1.9       
No Governmental Consents. No governmental, administrative or other third party consents or approvals are required
or necessary on the part of Subscriber in connection with the transactions contemplated by this Agreement.

 

2.2         
Company’s Representations, Warranties and Agreements. To induce the Subscriber to purchase the Shares, the
Company hereby represents and warrants to the Subscriber and agrees with the Subscriber as follows:

 

2.2.1       
Incorporation and Corporate Power. The Company is a Cayman Islands exempted company and is qualified to do business
in every jurisdiction in which the failure to so qualify would reasonably be expected to have a material adverse effect on the
financial condition, operating results or assets of the Company. The Company possesses all requisite corporate power and authority
necessary to carry out the transactions contemplated by this Agreement. Upon execution and delivery by the Company, this Agreement
will be a legal, valid and binding agreement of the Company, enforceable against the Company in accordance with its terms, except
as such enforceability may be limited by applicable bankruptcy, insolvency, fraudulent conveyance or similar laws affecting the
enforcement of creditors’ rights generally and subject to general principles of equity (regardless of whether enforcement
is sought in a proceeding at law or in equity).

 

2.2.2       
No Conflicts. The execution, delivery and performance of this Agreement and the consummation by the Company of the
transactions contemplated hereby do not violate, conflict with or constitute a default under (i) the memorandum and articles
of association of the Company, (ii) any agreement, indenture or instrument to which the Company is a party or (iii) any
law, statute, rule or regulation to which the Company is subject, or any agreement, order, judgment or decree to which the
Company is subject.

 

2.2.3       
Title to Securities. Upon issuance in accordance with, and payment pursuant to, the terms hereof, and registration
in the Company’s register of members, the Shares will be duly and validly issued, fully paid and nonassessable. Upon issuance
in accordance with, and payment pursuant to, the terms hereof, and registration in the Company’s register of members, the
Subscriber will have or receive good title to the Shares, free and clear of all liens, claims and encumbrances of any kind, other
than (a) transfer restrictions hereunder and other agreements to which the Shares may be subject, (b) transfer restrictions
under federal and state securities laws, and (c) liens, claims or encumbrances imposed due to the actions of the Subscriber.

 

2.2.4       
No Adverse Actions. There are no actions, suits, investigations or proceedings pending, threatened against or affecting
the Company which: (i) seek to restrain, enjoin, prevent the consummation of or otherwise affect the transactions contemplated
by this Agreement or (ii) question the validity or legality of any transactions or seeks to recover damages or to obtain other
relief in connection with any transactions.

 

    3 

     

    

 

		3.	Surrender and Cancellation of Shares.

 

3.1           Partial
or No Exercise of the Over-allotment Option. In the event the Over-allotment Option granted to the representative(s) of
the underwriters of the Company’s IPO is not exercised in full, the Subscriber acknowledges and agrees that it shall surrender
for cancellation any and all rights to such number of Shares (up to an aggregate of 1,125,000 Shares and pro rata based upon the
percentage of the Over-allotment Option exercised) such that immediately following such surrender, the Subscriber (and all other
initial shareholders prior to the IPO, if any) will own an aggregate number of Shares (not including ordinary shares issuable upon
exercise of any warrants or any ordinary shares purchased by Subscriber in the Company’s IPO or in the aftermarket) equal
to 20.0% of the issued and outstanding ordinary shares of the Company immediately following the IPO.

 

3.2           Termination
of Rights as Shareholder. If any of the Shares are surrendered and cancelled in accordance with this Section 3, then after
such time the Subscriber (or successor in interest), shall no longer have any rights as a holder of such Shares, and the Company
shall take such action as is appropriate to cancel such Shares.

 

4.            Waiver
of Liquidation Distributions; Redemption Rights. In connection with the Shares purchased pursuant to this Agreement, the
Subscriber hereby waives any and all right, title, interest or claim of any kind in or to any distributions by the Company from
the trust account which will be

 

established for the benefit of the Company’s public shareholders
and into which substantially all of the proceeds of the IPO will be deposited (the “Trust Account”), in the
event of a liquidation of the Company upon the Company’s failure to timely complete an initial business combination. For
purposes of clarity, in the event the Subscriber purchases ordinary shares in the IPO or in the aftermarket, any additional Shares
so purchased shall be eligible to receive any liquidating distributions by the Company. However, in no event will the Subscriber
have the right to redeem any ordinary shares into funds held in the Trust Account upon the successful completion of an initial
business combination.

 

		5.	Restrictions on Transfer.

 

5.1           Securities
Law Restrictions. In addition to any restrictions to be contained in that certain letter agreement (commonly known as an “Insider
Letter”) to be dated as of the closing of the IPO by and between Subscriber and the Company, Subscriber agrees not to
sell, transfer, pledge, hypothecate or otherwise dispose of all or any part of the Shares unless, prior thereto (a) a registration
statement on the appropriate form under the Securities Act and applicable state securities laws with respect to the Shares proposed
to be transferred shall then be effective or (b) the Company has received an opinion from counsel reasonably satisfactory
to the Company, that such registration is not required because such transaction is exempt from registration under the Securities
Act and the rules promulgated by the Securities and Exchange Commission thereunder and with all applicable state securities
laws.

 

5.2          
Restrictive Legends. Any certificates representing the Shares shall have endorsed thereon legends substantially
as follows:

 

“THE SECURITIES REPRESENTED HEREBY
HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS AND NEITHER THE
SECURITIES NOR ANY INTEREST THEREIN MAY BE OFFERED, SOLD, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO
AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT OR SUCH LAWS OR AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT AND SUCH LAWS
WHICH, IN THE OPINION OF COUNSEL, IS AVAILABLE.”

 

    4 

     

    

 

“THE SECURITIES REPRESENTED BY THIS
CERTIFICATE ARE SUBJECT TO LOCKUP PROVISIONS AND MAY NOT BE OFFERED, SOLD, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED DURING
THE TERM OF THE LOCKUP.”

 

5.3           Additional
Shares or Substituted Securities. In the event of the declaration of a share capitalization, the declaration of an extraordinary
dividend payable in a form other than Shares, a spin-off, a share sub-division, an adjustment in conversion ratio, a recapitalization
or a similar transaction affecting the Company’s outstanding Shares without receipt of consideration, any new, substituted
or additional securities or other property which are by reason of such transaction distributed with respect to any Shares subject
to this Section 5 or into which such Shares thereby become convertible shall immediately be subject to this Section 5
and Section 3. Appropriate adjustments to reflect the distribution of such securities or property shall be made to the number
and/or class of Shares subject to this Section 5 and Section 3.

 

5.4           Registration
Rights. Subscriber acknowledges that the Shares are being purchased pursuant to an exemption from the registration requirements
of the Securities Act and will become freely tradable only after certain conditions are met or they are registered pursuant to
a Registration and Shareholder Rights Agreement to be entered into with the Company prior to the closing of the IPO.

 

		6.	Other Agreements.

 

6.1           Further
Assurances. Subscriber agrees to execute such further instruments and to take such further action as may reasonably be necessary
to carry out the intent of this Agreement.

 

6.2           Notices.
All notices, statements or other documents which are required or contemplated by this Agreement shall be: (i) in writing and
delivered personally or sent by first class registered or certified mail, overnight courier service or facsimile or electronic
transmission to the address designated in writing, (ii) by facsimile to the number most recently provided to such party or
such other address or fax number as may be designated in writing by such party and (iii) by electronic mail, to the electronic
mail address most recently provided to such party or such other electronic mail address as may be designated in writing by such
party. Any notice or other communication so transmitted shall be deemed to have been given on the day of delivery, if delivered
personally, on the business day following receipt of written confirmation, if sent by facsimile or electronic transmission, one
(1) business day after delivery to an overnight courier service or five (5) days after mailing if sent by mail.

 

6.3           Entire
Agreement. This Agreement, together with that certain Insider Letter to be entered into between Subscriber and the Company,
substantially in the form to be filed as an exhibit to the Registration Statement on Form S-1 associated with the Company’s
IPO, embodies the entire agreement and understanding between the Subscriber and the Company with respect to the subject matter
hereof and supersedes all prior oral or written agreements and understandings relating to the subject matter hereof. No statement,
representation, warranty, covenant or agreement of any kind not expressly set forth in this Agreement shall affect, or be used
to interpret, change or restrict, the express terms and provisions of this Agreement.

 

6.4           Modifications
and Amendments. The terms and provisions of this Agreement may be modified or amended only by written agreement executed by
all parties hereto.

 

6.5           Waivers
and Consents. The terms and provisions of this Agreement may be waived, or consent for the departure therefrom granted, only
by a written document executed by the party entitled to the benefits of such terms or provisions. No such waiver or consent shall
be deemed to be or shall constitute a waiver or consent with respect to any other terms or provisions of this Agreement, whether
or

not similar. Each such waiver or consent shall be effective
only in the specific instance and for the purpose for which it was given, and shall not constitute a continuing waiver or consent.

 

    5 

     

    

 

6.6           Assignment.
The rights and obligations under this Agreement may not be assigned by either party hereto without the prior written consent of
the other party.

 

6.7           Benefit.
All statements, representations, warranties, covenants and agreements in this Agreement shall be binding on the parties hereto
and shall inure to the benefit of the respective successors and permitted assigns of each party hereto. Nothing in this Agreement
shall be construed to create any rights or obligations except among the parties hereto, and no person or entity shall be regarded
as a third-party beneficiary of this Agreement.

 

6.8           Governing
Law. This Agreement and the rights and obligations of the parties hereunder shall be construed in accordance with and governed
by the laws of Delaware applicable to contracts wholly performed within the borders of such state, without giving effect to the
conflict of law principles thereof.

 

6.9           Severability.
In the event that any court of competent jurisdiction shall determine that any provision, or any portion thereof, contained in
this Agreement shall be unreasonable or unenforceable in any respect, then such provision shall be deemed limited to the extent
that such court deems it reasonable and enforceable, and as so limited shall remain in full force and effect. In the event that
such court shall deem any such provision, or portion thereof, wholly unenforceable, the remaining provisions of this Agreement
shall nevertheless remain 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 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 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 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         Survival
of Representations and Warranties. All representations and warranties made by the parties hereto in this Agreement or in any
other agreement, certificate or instrument provided for or contemplated hereby, shall survive the execution and delivery hereof
and any investigations made by or on behalf of the parties.

 

6.12         No
Broker or Finder. Each of the parties hereto represents and warrants to the other that no broker, finder or other financial
consultant has acted on its behalf in connection with this Agreement or the transactions contemplated hereby in such a way as to
create any liability on the other. Each of the parties hereto agrees to indemnify and save the other harmless from any claim or
demand for commission or other compensation by any broker, finder, financial consultant or similar agent claiming to have been
employed by or on behalf of such party and to bear the cost of legal expenses incurred in defending against any such claim.

 

6.13         Headings
and Captions. The headings and captions of the various subdivisions of this 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.

6.14         Counterparts.
This 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 party, it being
understood that both parties need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission
or any other form of electronic delivery, 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.

 

6.15         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 hereto and no presumption
or burden of proof will arise favoring or disfavoring any party hereto because of the authorship of any provision of this Agreement.
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.

 

6.16         Mutual
Drafting. This Agreement is the joint product of the Subscriber and the Company and each provision hereof has been subject
to the mutual consultation, negotiation and agreement of such parties and shall not be construed for or against any party hereto.

 

7.            Voting
and Tender of Shares. Subscriber agrees to vote the Shares in favor of an initial business combination that the Company negotiates
and submits for approval to the Company’s shareholders and shall not seek redemption or repurchase with respect to such Shares.
Additionally, the Subscriber agrees not to tender any Shares in connection with a tender offer presented to the Company’s
shareholders in connection with an initial business combination negotiated by the Company.
