(ii) all conditions
precedent to the closing of the Transaction set forth in the Transaction Agreement, including the approval of the Company’s
shareholders, shall have been satisfied or waived;

 

(iii) no governmental

shall have instituted or threatened in writing a proceeding seeking to impose any such restraint or prohibition; and

 

d. The
obligation of the Company to consummate the Closing shall be subject to the satisfaction or valid waiver by the Company of the

which representations and warranties shall be true in all respects) at and as of the day of Closing; and

 

    	 	2

g. 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; provided, however, that the Subscriber shall not be required to make, seek or receive any filings, notifications, consents,
determinations, authorizations, permits, approvals, licenses or the like, or provide any documentation or information to any regulatory
or self-regulatory body having jurisdiction over the Company or the Subscriber other than information that is already included
in this Subscription Agreement or is otherwise in the public domain.

 

3. Company Representations
and Warranties. The Company represents and warrants to the Subscriber that:

 

a. The
Company (i) is duly organized, validly existing and in good standing under the laws of its jurisdiction of incorporation, (ii)
has the requisite power and authority to own, lease and operate its properties, to carry on its business as it is now being conducted
and to enter into and perform its obligations under this Subscription Agreement, and (iii) is duly licensed or qualified to conduct
its business and, if applicable, is in good standing under the laws of each jurisdiction (other than its jurisdiction of incorporation)
in which the conduct of its business or the ownership of its properties or assets requires such license or qualification, except,
with respect to the foregoing clause (iii), where the failure to be in good standing would not reasonably be expected to have a
Company Material Adverse Effect. For purposes of this Subscription Agreement, a “Company Material Adverse Effect”
means an event, change, development, occurrence, condition or effect with respect to the Company that, individually or in the aggregate,
has a material adverse effect on the business, financial condition or results of operations of the Company, taken as a whole.

 

    	 	3	 

     

    

 

b.
The Subscribed Shares, when issued and delivered to the Subscriber against full payment therefor in accordance with the terms
of this Subscription Agreement, will be validly issued, fully paid and non-assessable and will not have been issued in
violation of any preemptive rights created under the Company’s certificate of incorporation or the Delaware General
Corporation Law.

 

c.
This Subscription Agreement has been duly executed and delivered by the Company, and, assuming the due authorization,
execution and delivery of the same by the Subscriber, this Subscription Agreement shall constitute the valid and legally
binding obligation of the Company, enforceable against the Company in accordance with its terms, except as such
enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium and similar laws affecting creditors
generally and by the availability of equitable remedies.

 

d.
The execution and delivery of this Subscription Agreement, the issuance and sale of the Subscribed Shares and the compliance
by the Company with all of the provisions 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 the Company pursuant to the terms of (i) any indenture, mortgage, deed of trust, loan agreement,
lease, license or other agreement or instrument to which the Company is a party or by which the Company is bound or to which
any of the property or assets of the Company is subject; (ii) the organizational documents of the Company; 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 Company or any of its properties that, in the case of clauses (i) and (iii), would
reasonably be expected to have a Company Material Adverse Effect or have a material adverse effect on the Company’s
ability to consummate the transactions contemplated hereby, including the issuance and sale of the Subscribed Shares.

 

e.
The Company 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
(including The Nasdaq Stock Market (“Nasdaq”)) or other person in connection with the execution, delivery
and performance of this Subscription Agreement (including, without limitation, the issuance of the Subscribed 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
of 1933, as amended (the “Securities Act”), (iv) the filings required in accordance with
Section 8(b) of this Subscription Agreement; (v) those required by Nasdaq, including with respect to obtaining
shareholder approval, (vi) those required to consummate the Transaction as provided under the Transaction Agreement, and
(vii) the failure of which to obtain would not be reasonably likely to have a Company Material Adverse Effect or have a
material adverse effect on the Company’s ability to consummate the transactions contemplated hereby, including the
issuance and sale of the Subscribed Shares.

in the Company (collectively, “Equity Interests”) or securities convertible into or exchangeable or exercisable
for Equity Interests. As of the date hereof, the Company has no subsidiaries and does not own, directly or indirectly, interests

executive officers and independent directors agreed to vote in favor of any proposed Business Combination (as defined therein),
which includes the Transaction, and (B) as contemplated by the Transaction Agreement.

 

g. Except
for such matters as have not had and would not be reasonably likely to have a Company Material Adverse Effect or have a material

The issued and outstanding Class A Ordinary 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 Nasdaq under the symbol

no action that is designed to terminate the registration of the Class A Ordinary Shares under the Exchange Act.

 

i. The
Company has made available to the 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 Company with the Commission since
its initial registration of the Class A Ordinary 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. The Company
has timely filed each report, statement, schedule, prospectus, and registration statement that the Company 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.

c. The
execution and delivery of this Subscription Agreement, the purchase of the Subscribed Shares and the compliance by the Subscriber
with all of the provisions 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 the Subscriber pursuant
to the terms of (i) any indenture, mortgage, deed of trust, loan agreement, lease, license or other agreement or instrument
to which the Subscriber is a party or by which the Subscriber is bound or to which any of the property or assets of the Subscriber
is subject; (ii) the organizational documents of the 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 the Subscriber or any of
its properties that, in the case of clauses (i) and (iii), would reasonably be expected to have a Subscriber Material Adverse
Effect. For purposes of this Subscription Agreement, a “Subscriber Material Adverse Effect” means an event,
change, development, occurrence, condition or effect with respect to the Subscriber that would reasonably be expected to have a
material adverse effect on the Subscriber’s ability to consummate the transactions contemplated hereby, including the purchase
of the Subscribed Shares.

 

d. The
Subscriber (i) is 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 Subscribed Shares
only for its own account and not for the account of others, and (iii) is not acquiring the Subscribed Shares with a view to,
or for offer or sale in connection with, any distribution thereof in violation of the Securities Act (and has provided the Company
with the requested information on Annex A following the signature page hereto). The Subscriber is not an
entity formed for the specific purpose of acquiring the Subscribed Shares.

 

e. The
Subscriber understands that the Subscribed Shares are being offered in a transaction not involving any public offering within the
meaning of the Securities Act and that the Subscribed Shares have not been registered under the Securities Act. The Subscriber
understands that the Subscribed Shares may not be resold, transferred, pledged or otherwise disposed of by the Subscriber absent
an effective registration statement under the Securities Act, except (i) to the Company, or (ii) pursuant to an applicable
exemption from the registration requirements of the Securities Act, and, in each of cases (i) and (ii), in accordance with
any applicable securities laws of the states and other jurisdictions of the United States, and that any certificates or book-entry
position representing the Subscribed Shares shall contain a legend to such effect. The Subscriber understands and agrees that the
Subscribed Shares will be subject to transfer restrictions and, as a result of these transfer restrictions, the Subscriber may
not be able to readily resell the Subscribed Shares and may be required to bear the financial risk of an investment in the Subscribed
Shares for an indefinite period of time. The Subscriber understands that it has been advised to consult legal counsel prior to
making any offer, resale, pledge or transfer of any of the Subscribed Shares.

Subscriber understands and agrees that the Subscriber is purchasing the Subscribed Shares directly from the Company. The Subscriber
further acknowledges that there have not been, and the Subscriber is not relying on, any representations, warranties, covenants
and agreements made to the Subscriber by the Company, any other party to the Transaction or any other person or entity, expressly
or by implication, other than those representations, warranties, covenants and agreements of the Company included in this Subscription
Agreement.

 

g. The
Subscriber’s acquisition and holding of the Subscribed 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, or any applicable similar law.

 

h. In
making its decision to purchase the Subscribed Shares, the Subscriber has relied solely upon independent investigation made by
the Subscriber. The Subscriber acknowledges and agrees that the Subscriber has received such information as the Subscriber deems
necessary in order to make an investment decision with respect to the Subscribed Shares, including with respect to the Company
and the Transaction (including the company to be acquired in the Transaction and its respective subsidiaries). The Subscriber represents
and agrees that the Subscriber and the Subscriber’s professional advisor(s), if any, have had the full opportunity to ask
such questions, receive such answers and obtain such information as the Subscriber and such undersigned’s professional advisor(s),
if any, have deemed necessary to make an investment decision with respect to the Subscribed Shares. The
Subscriber acknowledges and agrees that neither Citigroup Global Markets Inc., acting as placement agent to the Company
(the “Placement Agent”), nor any Affiliate of the Placement Agent has provided Subscriber with any information
or advice with respect to the Subscribed Shares nor is such information or advice necessary or desired. Neither the Placement Agent
nor any of its Affiliates has made or makes any representation as to the Company or the quality of the Subscribed Shares and the
Placement Agent and any Affiliate may have acquired non-public information with respect to the Company which the Subscriber agrees
need not be provided to it. In connection with the issuance of the Subscribed Shares to the Subscriber, neither the Placement Agent
nor any of its Affiliates has acted as a financial advisor or fiduciary to the Subscriber.

 

i. The
Subscriber became aware of this offering of the Subscribed Shares solely by means of direct contact between the Subscriber and
the Company or by means of contact from the Placement Agent, and the Subscribed Shares were offered to the Subscriber solely by
direct contact between the Subscriber and the Company or by contact between the Subscriber and the Placement Agent. The Subscriber
did not become aware of this offering of the Subscribed Shares, nor were the Subscribed Shares offered to the Subscriber, by any
other means. The Subscriber acknowledges that the Company represents and warrants that the Subscribed 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.

 

    	 	8	 

     

    

 

j. The
Subscriber acknowledges that it is aware that there are substantial risks incident to the purchase and ownership of the Subscribed
Shares. The 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 Subscribed Shares, and the Subscriber has sought such accounting, legal and tax advice as the
Subscriber has considered necessary to make an informed investment decision.

 

k. The
Subscriber has adequately analyzed and fully considered the risks of an investment in the Subscribed Shares and determined that
the Subscribed Shares are a suitable investment for the Subscriber and that the Subscriber is able at this time and in the foreseeable
future to bear the economic risk of a total loss of the Subscriber’s investment in the Company. The Subscriber acknowledges
specifically that a possibility of total loss exists.

 

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

 

m. The
Subscriber is not (i) a person or entity named on the List of Specially Designated Nationals and Blocked Persons administered

issued by the President of the United States and administered by OFAC (“OFAC List”), or a person or entity prohibited
by any OFAC sanctions program, (ii) a Designated National as defined in the Cuban Assets Control Regulations, 31 C.F.R. Part 515,
or (iii) a non-U.S. shell bank or providing banking services indirectly to a non-U.S. shell bank (collectively, a “Prohibited
Investor”). The Subscriber represents that if it is a financial institution subject to the Bank Secrecy Act (31 U.S.C.
Section 5311 et seq.), as amended by the USA PATRIOT Act of 2001 and its implementing regulations (collectively, the “BSA/PATRIOT
Act”), that the Subscriber maintains policies and procedures reasonably designed to comply with applicable obligations
under the BSA/PATRIOT Act. The Subscriber also represents that, to the extent required, it maintains policies and procedures reasonably
designed for the screening of its investors against the OFAC sanctions programs, including the OFAC List. The Subscriber further
represents and warrants that, to the extent required, it maintains policies and procedures reasonably designed to ensure that the
funds held by the Subscriber and used to purchase the Subscribed Shares were legally derived.

 

n. The
Subscriber does not have, and during the 30-day period immediately prior hereto the Subscriber has not entered into, any “put
equivalent position” as such term is defined in Rule 16a-1 under the Exchange Act or short sale positions with respect to
the securities of the Company. In addition, the Subscriber shall comply with all applicable provisions of Regulation M promulgated
under the Securities Act.

 

    	 	9	 

     

    

 

o. The
Subscriber acknowledges and agrees that the certificate or book-entry position representing the Subscribed Shares will bear or
reflect, as applicable, a legend substantially similar to the following:

 

“THIS
SECURITY WAS ORIGINALLY ISSUED IN A TRANSACTION EXEMPT FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES
ACT”), AND THIS SECURITY MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN
APPLICABLE EXEMPTION THEREFROM.  THE HOLDER OF THIS SECURITY AGREES FOR THE BENEFIT OF THE COMPANY THAT (A) THIS SECURITY
MAY BE OFFERED, RESOLD, PLEDGED OR OTHERWISE TRANSFERRED, ONLY (I) PURSUANT TO ANY AVAILABLE EXEMPTION FROM THE REGISTRATION
REQUIREMENTS OF THE SECURITIES ACT, (II) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, OR (III) TO
THE COMPANY, IN EACH OF CASES (I) THROUGH (III) IN ACCORDANCE WITH ANY APPLICABLE SECURITIES LAWS OF ANY STATE OF
THE UNITED STATES, AND (B) THE HOLDER WILL NOTIFY ANY SUBSEQUENT PURCHASER OF THIS SECURITY FROM IT OF THE RESALE RESTRICTIONS
REFERRED TO IN (A) ABOVE. THE COMPANY MAY REQUIRE THE DELIVERY OF A WRITTEN OPINION OF COUNSEL, CERTIFICATIONS AND/OR
ANY OTHER INFORMATION IT REASONABLY REQUIRES TO CONFIRM THE SECURITIES ACT EXEMPTION FOR SUCH TRANSACTION.”

 

5. Registration
Rights.  

 

a. The
Company agrees that, within forty-five (45) calendar days after the Closing (the “Filing Deadline”), the Company
will use commercially reasonable efforts to file with the Commission a registration statement registering the resale of the Subscribed
Shares (the “Registration Statement”), and the Company 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 75th calendar
day (or 105th calendar day if the Commission notifies the Company that it will “review” the Registration Statement)
following the Filing Deadline (such date, the “Effectiveness Date”); provided, however, that the Company’s
obligations to include the Subscribed Shares in the Registration Statement are contingent upon the Subscriber furnishing in writing
to the Company such information regarding the Subscriber, the securities of the Company held by the Subscriber and the intended
method of disposition of the Subscribed Shares as shall be reasonably requested by the Company to effect the registration of the
Subscribed Shares, and shall execute such documents in connection with such registration as the Company may reasonably request
that are customary of a selling stockholder in similar situations. The Company will use its commercially reasonable efforts to
maintain the continuous effectiveness of the Registration Statement until the earliest of (i) the date on which such securities
may be resold without volume or manner of sale limitations pursuant to Rule 144 promulgated under the Securities Act, (ii) the
date on which the Subscriber has notified the Company that such securities have actually been sold and (iii) the date which is
three years after the Closing. For purposes of clarification, any failure by the Company to file the Registration Statement by
the Filing Deadline or to effect such Registration Statement by the Effectiveness Date shall not otherwise relieve the Company
of its obligations to file or effect the Registration Statement set forth in this Section 5.

 

    	 	10	 

     

    

 

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

 

(i) except
for such times as the Company 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 Company determines to obtain, continuously effective with respect to the 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) the Subscriber ceases to hold any Subscribed Shares or (ii) the date all Subscribed Shares held by
the 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 Company 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 Company is required hereunder to keep a Registration Statement
effective is referred to herein as the “Registration Period.”

 

(ii) advise
the 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 Company of any notification with respect to the suspension of the qualification
of the Subscribed 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 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;

 

    	 	11	 

     

    

 

		(6)	Notwithstanding anything to the contrary set forth herein, the Company shall not, when so advising
the Subscriber of such events, provide the Subscriber with any material, nonpublic information regarding the Company.

 

(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 Company is permitted hereunder to suspend, and has
suspended, the use of a prospectus forming part of a Registration Statement, the Company 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 Subscribed
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 Subscribed Shares to be listed on each securities exchange or market, if any, on which
equity securities issued by the Company have been listed;

 

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

 

c. Notwithstanding
anything to the contrary in this Subscription Agreement, the Company shall be entitled to delay or postpone the effectiveness of
the Registration Statement, and from time to time to require the Subscriber not to sell under the Registration Statement or to
suspend the effectiveness thereof, if the negotiation or consummation of a transaction by the Company or its subsidiaries is pending
or an event has occurred, which negotiation, consummation or event the Company’s board of directors reasonably believes,
upon the advice of legal counsel, would require additional disclosure by the Company in the Registration Statement of material
information that the Company 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 Company’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 Company 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 Company 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, the Subscriber agrees that (i) it will immediately discontinue offers and sales of the Subscribed Shares
under the Registration Statement (excluding, for the avoidance of doubt, sales conducted pursuant to Rule 144) until the Subscriber
receives copies of a supplemental or amended prospectus (which the Company 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 Company 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 Company unless otherwise required by law or subpoena. If so directed by the Company,
the Subscriber will deliver to the Company or, in the Subscriber’s sole discretion destroy, all copies of the prospectus
covering the Subscribed Shares in the Subscriber’s possession; provided, however, that this obligation to deliver or destroy
all copies of the prospectus covering the Subscribed Shares shall not apply (i) to the extent the 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.

 

    	 	12	 

     

    

 

d. The
Subscriber may deliver written notice (including via email in accordance with Section 8(l)) (an “Opt-Out Notice”)
to the Company requesting that the Subscriber not receive notices from the Company otherwise required by this Section 5; provided,
however, that the Subscriber may later revoke any such Opt-Out Notice in writing. Following receipt of an Opt-Out Notice from the
Subscriber (unless subsequently revoked), (i) the Company shall not deliver any such notices to the Subscriber and the Subscriber
shall no longer be entitled to the rights associated with any such notice and (ii) each time prior to the Subscriber’s intended
use of an effective Registration Statement, the Subscriber will notify the Company 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(d)) and the related suspension period remains in effect, the Company will so notify the Subscriber,
within one (1) Business Day of the Subscriber’s notification to the Company, by delivering to the Subscriber a copy of such
previous notice of Suspension Event, and thereafter will provide the Subscriber with the related notice of the conclusion of such
Suspension Event immediately upon its availability.

 

e. The
Company shall, notwithstanding any termination of this Subscription Agreement, indemnify, defend and hold harmless the Subscriber
(to the extent a seller under the Registration Statement), the officers, directors, agents, partners, members, managers, stockholders,
affiliates, employees and investment advisers of each of them, each person who controls the Subscriber (within the meaning of Section 15
of the Securities Act or Section 20 of the Exchange Act) and the officers, directors, partners, members, managers, stockholders,
agents, affiliates, employees and investment advisers of each such controlling person, to the fullest extent permitted by applicable
law, from and against any and all losses, claims, damages, liabilities, costs (including, without limitation, reasonable attorneys’
fees) and expenses (collectively, “Losses”), as incurred, that arise out of or are based upon (i) any untrue
or alleged untrue statement of a material fact contained in the Registration Statement, any prospectus included in the Registration
Statement or any form of prospectus or in any amendment or supplement thereto or in any preliminary prospectus, or arising out
of or relating to any omission or alleged omission to state a material fact required to be stated therein or necessary to make
the statements therein (in the case of any prospectus or form of prospectus or supplement thereto, in light of the circumstances
under which they were made) not misleading, or (ii) any violation or alleged violation by the Company of the Securities Act,
Exchange Act or any state securities law or any rule or regulation thereunder, in connection with the performance of its obligations
under this Section 5, except to the extent, but only to the extent, that such untrue statements, alleged untrue statements,
omissions or alleged omissions are based upon information regarding the Subscriber furnished in writing to the Company by the Subscriber
expressly for use therein. The Company shall notify the Subscriber promptly of the institution, threat or assertion of any proceeding
arising from or in connection with the transactions contemplated by this Section 5 of which the Company is aware. Such indemnity
shall remain in full force and effect regardless of any investigation made by or on behalf of an indemnified party and shall survive
the transfer of the Subscribed Shares by the Subscriber.

 

    	 	13	 

     

    

 

f. The
Subscriber shall, severally and not jointly with any other subscriber, indemnify and hold harmless the Company, its directors,
officers, agents and employees, each person who controls the Company (within the meaning of Section 15 of the Securities Act
and Section 20 of the Exchange Act), and the directors, officers, agents or employees of such controlling persons, to the
fullest extent permitted by applicable law, from and against all Losses, as incurred, arising out of or are based upon any untrue
or alleged untrue statement of a material fact contained in any Registration Statement, any prospectus included in the Registration
Statement, or any form of prospectus, or in any amendment or supplement thereto or in any preliminary prospectus, or arising out
of or relating to any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements
therein (in the case of any prospectus, or any form of prospectus or supplement thereto, in light of the circumstances under which
they were made) not misleading to the extent, but only to the extent, that such untrue statements or omissions are based upon information
regarding the Subscriber furnished in writing to the Company by the Subscriber expressly for use therein. In no event shall the
liability of the Subscriber be greater in amount than the dollar amount of the net proceeds received by the Subscriber upon the
sale of the Subscribed Shares giving rise to such indemnification obligation.

 

g. The
Subscriber shall not execute any short sales or engage in other hedging transactions of any kind with respect to securities of
the Company during the period from the date of the Closing through the date that is 45 consecutive days thereafter.

 

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 Transaction Agreement is terminated in accordance with its terms, (b) upon
the mutual written agreement of the Company and the Subscriber to terminate this Subscription Agreement, or (c) if, on the
Closing Date of the Transaction, any of the conditions to Closing set forth in Section 2 of this Subscription Agreement have
not been satisfied as of the time required hereunder to be so satisfied or waived by the party entitled to grant such waiver and,
as a result thereof, the transactions contemplated by this Subscription Agreement are not consummated; 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 Company
shall notify the Subscriber of the termination of the Transaction Agreement promptly after the termination thereof.

 

    	 	14	 

     

    

 

7. Trust
Account Waiver. The Subscriber acknowledges that the Company is a blank check company with the powers and privileges to effect
a merger, asset acquisition, reorganization or similar business combination involving the Company and one or more businesses or
assets. The Subscriber further acknowledges that, as described in the Company’s prospectus relating to its initial public
offering dated November 2, 2017 (the “Prospectus”) available at www.sec.gov, substantially all of the Company’s
assets consist of the cash proceeds of the Company’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 Company, its public stockholders and the underwriters of the Company’s initial public offering. Except with respect
to interest earned on the funds held in the Trust Account that may be released to the Company 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
Company entering into this Subscription Agreement, the receipt and sufficiency of which are hereby acknowledged, the Subscriber,
solely on behalf of itself and its officers, directors and affiliates, hereby irrevocably waives any and all right, title and interest,
or any claim of any kind they have or may have in the future, 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.

prior to the closing of the Transaction (as defined herein) and in connection therewith change its name to Strike, Inc.) (the “Company”),
and the subscribers listed on Schedule A hereto (each such subscriber a “Subscriber” and together, the
“Subscribers”).

 

WHEREAS,
concurrently with the execution of this Subscription Agreement, the Company is entering into a Transaction Agreement and Plan of
Merger with Strike Capital, LLC (“Strike”), OEP Secondary Fund (Strike), LLC, One Equity Partners Secondary
Fund, L.P., the other unitholders of Strike signatory thereto, SES Blocker Merger Sub, LLC and OEP-Strike Seller Representative,
LLC, solely in its capacity as the Sellers Representative (as defined therein) (the “Transaction Agreement”
and the transactions contemplated by the Transaction Agreement, the “Transaction”);

 

WHEREAS,
prior to the closing of the Transaction, the Company will domesticate as a Delaware corporation in accordance with Section 388
of the Delaware General Corporation Law and Article 206 of the Cayman Islands Companies Law (2018 Revision) (the “Domestication”),
and in connection with the Domestication and the Transaction, change its name to Strike, Inc.;

 

WHEREAS,
in connection with the Transaction, each Subscriber desires to subscribe for and purchase from the Company, subsequent to the effectiveness
of the Domestication and substantially concurrent with the consummation of the Transaction, that number of shares of the Company’s
Class A common stock, par value $0.0001 per share (“Class A Common Stock”), set forth next to its name on Schedule
A hereto (the “Subscribed Shares”) for a purchase price of $10.00 per share (the “Per Share Price”
and the aggregate of such Per Share Price for all Subscribed Shares being referred to herein as the “Purchase Price”),
and the Company desires to issue and sell to each Subscriber the Subscribed Shares in consideration of the payment of the Purchase
Price by or on behalf of such Subscriber to the Company; and

(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.

its delivery instructions) or to a custodian designated by such Subscriber, as applicable. Upon confirmation by such Subscriber’s
custodian of receipt of the certificated shares, such Subscriber shall deliver to the Company the Purchase Price for its Subscribed
Shares by wire transfer of U.S. dollars in immediately available funds to the account specified by the Company in the Closing Notice.

c. The Closing

illegal or otherwise restraining 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 restraint or prohibition; and

 

    	 	2

of the Company to consummate the Closing shall be subject to the satisfaction or valid waiver by the Company of the additional
conditions that, on the day of Closing:

 

(i) all representations
and warranties of each Subscriber contained in this Subscription Agreement shall be true and correct in all material respects (other

which representations and warranties shall be true in all respects) at and as of the day of Closing; and

 

(ii) Each
Subscriber shall have performed, satisfied and complied in all material respects with all covenants, agreements and conditions

(i) all representations
and warranties of the Company contained in this Subscription Agreement shall be true and correct in all material respects (other

3. Company Representations
and Warranties. The Company represents and warrants to the Subscribers that:

 

a. The Company
(i) is duly organized, validly existing and in good standing under the laws of its jurisdiction of incorporation, (ii) has the
requisite power and authority to own, lease and operate its properties, to carry on its business as it is now being conducted and
to enter into and perform its obligations under this Subscription Agreement, and (iii) is duly licensed or qualified to conduct
its business and, if applicable, is in good standing under the laws of each jurisdiction (other than its jurisdiction of incorporation)
in which the conduct of its business or the ownership of its properties or assets requires such license or qualification, except,
with respect to the foregoing clause (iii), where the failure to be in good standing would not reasonably be expected to have a
Company Material Adverse Effect. For purposes of this Subscription Agreement, a “Company Material Adverse Effect”
means an event, change, development, occurrence, condition or effect with respect to the Company that, individually or in the aggregate,
has a material adverse effect on the business, financial condition or results of operations of the Company, taken as a whole.

 

b. The Subscribed
Shares, when issued and delivered to the Subscribers against full payment therefor in accordance with the terms of this Subscription
Agreement, will be validly issued, fully paid and non-assessable and will not have been issued in violation of any preemptive rights
created under the Company’s certificate of incorporation or the Delaware General Corporation Law.

 

c. This
Subscription Agreement has been duly executed and delivered by the Company, and, assuming the due authorization, execution and
delivery of the same by each Subscriber, this Subscription Agreement shall constitute the valid and legally binding obligation
of the Company, enforceable against the Company in accordance with its terms, except as such enforceability may be limited by bankruptcy,
insolvency, reorganization, moratorium and similar laws affecting creditors generally and by the availability of equitable remedies.

 

d. The execution
and delivery of this Subscription Agreement, the issuance and sale of the Subscribed Shares and the compliance by the Company with
all of the provisions 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 the Company pursuant to the terms of (i) any
indenture, mortgage, deed of trust, loan agreement, lease, license or other agreement or instrument to which the Company is a party
or by which the Company is bound or to which any of the property or assets of the Company is subject; (ii) the organizational
documents of the Company; 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 Company or any of its properties that, in the case of clauses (i)
and (iii), would reasonably be expected to have a Company Material Adverse Effect or have a material adverse effect on the Company’s
ability to consummate the transactions contemplated hereby, including the issuance and sale of the Subscribed Shares.

 

e. The Company
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 (including The Nasdaq
Stock Market (“Nasdaq”)) or other person in connection with the execution, delivery and performance of this
Subscription Agreement (including, without limitation, the issuance of the Subscribed 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 of 1933, as amended (the “Securities Act”),
(iv) the filings required in accordance with Section 8(b) of this Subscription Agreement; (v) those required by
Nasdaq, including with respect to obtaining shareholder approval, (vi) those required to consummate the Transaction as provided
under the Transaction Agreement, and (vii) the failure of which to obtain would not be reasonably likely to have a Company
Material Adverse Effect or have a material adverse effect on the Company’s ability to consummate the transactions contemplated
hereby, including the issuance and sale of the Subscribed Shares.

issued, are fully paid and are non-assessable and are not subject to preemptive rights and (ii) outstanding Warrants have
been duly authorized and validly issued, are fully paid and are not subject to preemptive rights. Except as set forth above and

options, warrants or other rights to subscribe for, purchase or acquire from the Company any Ordinary Shares or other equity interests
in the Company (collectively, “Equity Interests”) or securities convertible into or exchangeable or exercisable
for Equity Interests. As of the date hereof, the Company has no subsidiaries and does not own, directly or indirectly, interests
or investments (whether equity or debt) in any person, whether incorporated or unincorporated. There are no stockholder agreements,
voting trusts or other agreements or understandings to which the Company is a party or by which it is bound relating to the voting
of any Equity Interests, other than (A) the letter agreements entered into by the Company in connection with the Company’s
initial public offering on November 2, 2017 and January 31, 2018 pursuant to which Sentinel Management Holdings, LLC and the Company’s
executive officers and independent directors agreed to vote in favor of any proposed Business Combination (as defined therein),
which includes the Transaction, and (B) as contemplated by the Transaction Agreement.

 

g. Except
for such matters as have not had and would not be reasonably likely to have a Company Material Adverse Effect or have a material
adverse effect on the Company’s ability to consummate the transactions contemplated hereby, including the issuance and sale
of the Subscribed Shares, as of the date hereof, there is no (i) suit, action, proceeding or arbitration before a governmental
authority or arbitrator pending, or, to the knowledge of the Company, threatened against the Company or (ii) judgment, decree,
injunction, ruling or order of any governmental authority or arbitrator outstanding against the Company.

 

    	 	5	 

     

    

 

h. The issued
and outstanding Class A Ordinary 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 Nasdaq under the symbol “STNL.” There
is no suit, action, proceeding or investigation pending or, to the knowledge of the Company, threatened against the Company by
Nasdaq or the Commission with respect to any intention by such entity to deregister the Class A Ordinary Shares or prohibit or
terminate the listing of the Class A Ordinary Shares on Nasdaq. The Company has taken no action that is designed to terminate the
registration of the Class A Ordinary Shares under the Exchange Act.

 

i. The Company
has made available to each 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 Company with the Commission since
its initial registration of the Class A Ordinary 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. The Company
has timely filed each report, statement, schedule, prospectus, and registration statement that the Company 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.

 

j. Upon
consummation of the Transaction, the issued and outstanding shares of Common Stock will be registered pursuant to Section 12(b)
of the Exchange Act and will be listed for trading on the New York Stock Exchange.

 

k. Assuming
the accuracy of each 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 Subscribed Shares by the Company to any of the
Subscribers.

 

l. Neither
the Company 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) in connection with any offer or sale of the Subscribed Shares.

 

4. Subscriber

that:

 

a. The Subscriber
(i) is duly organized, validly existing and in good standing under the Laws of its jurisdiction of incorporation, (ii) has the
requisite power and authority to enter into and perform its obligations under this Subscription Agreement.

 

b. This
Subscription Agreement has been duly executed and delivered by the Subscriber, and, assuming the due authorization, execution and
delivery of the same by the Company, this Subscription Agreement shall constitute the valid and legally binding obligation of the
Subscriber, enforceable against the Subscriber in accordance with its terms, except as such enforceability may be limited by bankruptcy,
insolvency, reorganization, moratorium and similar laws affecting creditors generally and by the availability of equitable remedies.

 

    	 	6	 

     

    

 

c. The execution
and delivery of this Subscription Agreement, the purchase of the Subscribed Shares and the compliance by the Subscriber with all
of the provisions 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 the Subscriber pursuant to the terms of
(i) any indenture, mortgage, deed of trust, loan agreement, lease, license or other agreement or instrument to which the Subscriber
is a party or by which the Subscriber is bound or to which any of the property or assets of the Subscriber is subject; (ii) the
organizational documents of the 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 the Subscriber or any of its properties that, in the
case of clauses (i) and (iii), would reasonably be expected to have a Subscriber Material Adverse Effect. For purposes of
this Subscription Agreement, a “Subscriber Material Adverse Effect” means an event, change, development, occurrence,
condition or effect with respect to any of the Subscribers that would reasonably be expected to have a material adverse effect
on such Subscriber’s ability to consummate the transactions contemplated hereby, including the purchase of the Subscribed
Shares.

 

d. The Subscriber
(i) is 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 Subscribed Shares only
for its own account and not for the account of others, and (iii) is not acquiring the Subscribed Shares with a view to, or
for offer or sale in connection with, any distribution thereof in violation of the Securities Act (and has provided the Company
with the requested information on Annex A following the signature page hereto). The Subscriber is not an
entity formed for the specific purpose of acquiring the Subscribed Shares.

 

e. The Subscriber
understands that the Subscribed Shares are being offered in a transaction not involving any public offering within the meaning
of the Securities Act and that the Subscribed Shares have not been registered under the Securities Act. The Subscriber understands
that the Subscribed Shares may not be resold, transferred, pledged or otherwise disposed of by the Subscriber absent an effective
registration statement under the Securities Act, except (i) to the Company, or (ii) pursuant to an applicable exemption
from the registration requirements of the Securities Act, and, in each of cases (i) and (ii), in accordance with any applicable
securities laws of the states and other jurisdictions of the United States, and that any certificates or book-entry position representing
the Subscribed Shares shall contain a legend to such effect. The Subscriber understands and agrees that the Subscribed Shares will
be subject to transfer restrictions and, as a result of these transfer restrictions, the Subscriber may not be able to readily
resell the Subscribed Shares and may be required to bear the financial risk of an investment in the Subscribed Shares for an indefinite
period of time. The Subscriber understands that it has been advised to consult legal counsel prior to making any offer, resale,
pledge or transfer of any of the Subscribed Shares.

 

    	 	7	 

     

    

 

f. The Subscriber
understands and agrees that the Subscriber is purchasing the Subscribed Shares directly from the Company. The Subscriber further
acknowledges that there have not been, and the Subscriber is not relying on, any representations, warranties, covenants and agreements
made to the Subscriber by the Company, any other party to the Transaction or any other person or entity, expressly or by implication,
other than those representations, warranties, covenants and agreements of the Company included in this Subscription Agreement.

 

g. The Subscriber’s
acquisition and holding of the Subscribed 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, or any applicable similar law.

 

h. In making
its decision to purchase the Subscribed Shares, the Subscriber has relied solely upon independent investigation made by the Subscriber.
The Subscriber acknowledges and agrees that the Subscriber has received such information as the Subscriber deems necessary in order
to make an investment decision with respect to the Subscribed Shares, including with respect to the Company and the Transaction
(including the company to be acquired in the Transaction and its respective subsidiaries). The Subscriber represents and agrees
that the Subscriber and the Subscriber’s professional advisor(s), if any, have had the full opportunity to ask such questions,
receive such answers and obtain such information as the Subscriber and such undersigned’s professional advisor(s), if any,
have deemed necessary to make an investment decision with respect to the Subscribed Shares. The Subscriber
acknowledges and agrees that neither Citigroup Global Markets Inc., acting as placement agent to the Company (the “Placement
Agent”), nor any Affiliate of the Placement Agent has provided Subscriber with any information or advice with respect
to the Subscribed Shares nor is such information or advice necessary or desired. Neither the Placement Agent nor any of its Affiliates
has made or makes any representation as to the Company or the quality of the Subscribed Shares and the Placement Agent and any
Affiliate may have acquired non-public information with respect to the Company which the Subscriber agrees need not be provided
to it. In connection with the issuance of the Subscribed Shares to the Subscriber, neither the Placement Agent nor any of its Affiliates
has acted as a financial advisor or fiduciary to the Subscriber.

 

i. The Subscriber
became aware of this offering of the Subscribed Shares solely by means of direct contact between the Subscriber and the Company
or by means of contact from the Placement Agent, and the Subscribed Shares were offered to the Subscriber solely by direct contact
between the Subscriber and the Company or by contact between the Subscriber and the Placement Agent. The Subscriber did not become
aware of this offering of the Subscribed Shares, nor were the Subscribed Shares offered to the Subscriber, by any other means.
The Subscriber acknowledges that the Company represents and warrants that the Subscribed 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.

 

    	 	8	 

     

    

 

j. The Subscriber
acknowledges that it is aware that there are substantial risks incident to the purchase and ownership of the Subscribed Shares.
The 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 Subscribed Shares, and the Subscriber has sought such accounting, legal and tax advice as the Subscriber
has considered necessary to make an informed investment decision.

 

k. The Subscriber
has adequately analyzed and fully considered the risks of an investment in the Subscribed Shares and determined that the Subscribed
Shares are a suitable investment for the Subscriber and that the Subscriber is able at this time and in the foreseeable future
to bear the economic risk of a total loss of the Subscriber’s investment in the Company. The Subscriber acknowledges specifically
that a possibility of total loss exists.

 

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

 

m. The Subscriber
is not (i) a person or entity named on the List of Specially Designated Nationals and Blocked Persons administered by the
U.S. Treasury Department’s Office of Foreign Assets Control (“OFAC”) or in any Executive Order issued
by the President of the United States and administered by OFAC (“OFAC List”), or a person or entity prohibited
by any OFAC sanctions program, (ii) a Designated National as defined in the Cuban Assets Control Regulations, 31 C.F.R. Part 515,
or (iii) a non-U.S. shell bank or providing banking services indirectly to a non-U.S. shell bank (collectively, a “Prohibited
Investor”). The Subscriber represents that if it is a financial institution subject to the Bank Secrecy Act (31 U.S.C.
Section 5311 et seq.), as amended by the USA PATRIOT Act of 2001 and its implementing regulations (collectively, the “BSA/PATRIOT
Act”), that the Subscriber maintains policies and procedures reasonably designed to comply with applicable obligations
under the BSA/PATRIOT Act. The Subscriber also represents that, to the extent required, it maintains policies and procedures reasonably
designed for the screening of its investors against the OFAC sanctions programs, including the OFAC List. The Subscriber further
represents and warrants that, to the extent required, it maintains policies and procedures reasonably designed to ensure that the
funds held by the Subscriber and used to purchase the Subscribed Shares were legally derived.

 

n. The Subscriber
does not have, and during the 30-day period immediately prior hereto such Subscriber has not entered into, any “put equivalent
position” as such term is defined in Rule 16a-1 under the Exchange Act or short sale positions with respect to the securities
of the Company. In addition, the Subscriber shall comply with all applicable provisions of Regulation M promulgated under the Securities
Act.

 

    	 	9	 

     

    

 

o. The Subscriber
acknowledges and agrees that the certificate or book-entry position representing the Subscribed Shares will bear or reflect, as
applicable, a legend substantially similar to the following:

 

“THIS
SECURITY WAS ORIGINALLY ISSUED IN A TRANSACTION EXEMPT FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES
ACT”), AND THIS SECURITY MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN
APPLICABLE EXEMPTION THEREFROM.  THE HOLDER OF THIS SECURITY AGREES FOR THE BENEFIT OF THE COMPANY THAT (A) THIS SECURITY
MAY BE OFFERED, RESOLD, PLEDGED OR OTHERWISE TRANSFERRED, ONLY (I) PURSUANT TO ANY AVAILABLE EXEMPTION FROM THE REGISTRATION
REQUIREMENTS OF THE SECURITIES ACT, (II) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, OR (III) TO
THE COMPANY, IN EACH OF CASES (I) THROUGH (III) IN ACCORDANCE WITH ANY APPLICABLE SECURITIES LAWS OF ANY STATE OF
THE UNITED STATES, AND (B) THE HOLDER WILL NOTIFY ANY SUBSEQUENT PURCHASER OF THIS SECURITY FROM IT OF THE RESALE RESTRICTIONS
REFERRED TO IN (A) ABOVE. THE COMPANY MAY REQUIRE THE DELIVERY OF A WRITTEN OPINION OF COUNSEL, CERTIFICATIONS AND/OR
ANY OTHER INFORMATION IT REASONABLY REQUIRES TO CONFIRM THE SECURITIES ACT EXEMPTION FOR SUCH TRANSACTION.”

 

5. Registration
Rights.  

 

a. The Company
agrees that, within forty-five (45) calendar days after the Closing (the “Filing Deadline”), the Company will
use commercially reasonable efforts to file with the Commission a registration statement registering the resale of the Subscribed
Shares (the “Registration Statement”), and the Company 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 75th calendar
day (or 105th calendar day if the Commission notifies the Company that it will “review” the Registration Statement)
following the Filing Deadline (such date, the “Effectiveness Date”); provided, however, that the Company’s
obligations to include the Subscribed Shares in the Registration Statement are contingent upon each Subscriber furnishing in writing
to the Company such information regarding such Subscriber, the securities of the Company held by such Subscriber and the intended
method of disposition of the Subscribed Shares as shall be reasonably requested by the Company to effect the registration of the
Subscribed Shares, and shall execute such documents in connection with such registration as the Company may reasonably request
that are customary of a selling stockholder in similar situations. The Company will use its commercially reasonable efforts to
maintain the continuous effectiveness of the Registration Statement until the earliest of (i) the date on which such securities
may be resold without volume or manner of sale limitations pursuant to Rule 144 promulgated under the Securities Act, (ii) the
date on which the Subscribers have notified the Company that such securities have actually been sold and (iii) the date which is
three years after the Closing. For purposes of clarification, any failure by the Company to file the Registration Statement by
the Filing Deadline or to effect such Registration Statement by the Effectiveness Date shall not otherwise relieve the Company
of its obligations to file or effect the Registration Statement set forth in this Section 5.

 

    	 	10	 

     

    

 

b. The Company
further agrees that, in the event that (i) the Registration Statement is not filed with the Commission on or prior to the Filing
Deadline, (ii) the Registration Statement has not been declared effective by the Commission by the Effectiveness Date, (iii) after
such Registration Statement is declared effective by the Commission, (A) such Registration Statement ceases for any reason (including
without limitation by reason of a stop order, or the Company’s failure to update the Registration Statement), to remain continuously
effective as to all Subscribed Shares for which it is required to be effective or (B) a Subscriber is not permitted to utilize
the Registration Statement to resell its Subscribed Shares (in each case of (A) and (B), other than within the time period(s) permitted
by this Agreement), or (iv) 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 of the Subscribed Shares, the Company 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 the Subscribers who are not affiliates are unable to sell their Subscribed Shares without
restriction under Rule 144 (or any successor thereto) (each such event referred to in clauses (i) through (iv), 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 such 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 Company 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 the Subscriber pursuant to this Subscription Agreement for any Subscribed Shares held by the Subscriber on the Default
Date; provided, however, that if such Subscriber fails to provide the Company with any information requested by the Company that
is required to be provided in such Registration Statement with respect to such 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 such Subscriber
shall be extended until two (2) Business Days following the date of receipt by the Company of such required information from such
Subscriber; and in no event shall the Company be required hereunder to pay to such Subscriber pursuant to this Subscription Agreement
an aggregate amount that exceeds 5.0 % of the aggregate Purchase Price paid by such Subscriber for its Subscribed 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 Company shall deliver the cash payment to such Subscriber with respect
to any Liquidated Damages by the fifth Business Day after the date payable. If the Company fails to pay said cash payment to such
Subscriber in full by the fifth Business Day after the date payable, the Company 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 any Subscriber with respect to any period during which all of such Subscriber’s Subscribed Shares may be sold by such
Subscriber without volume or manner of sale restrictions under Rule 144 and the Company is in compliance with the current public
information requirements under Rule 144(c)(1) (or Rule 144(i)(2), if applicable).

 

    	 	11	 

     

    

 

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

 

(i) except
for such times as the Company 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 Company determines to obtain, continuously effective with respect to the Subscribers, 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) the Subscribers cease to hold any Subscribed Shares or (ii) the date all Subscribed Shares held by
the Subscribers 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 Company 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 Company is required hereunder to keep a Registration Statement
effective is referred to herein as the “Registration Period.”

 

(ii) advise
each 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 Company of any notification with respect to the suspension of the qualification
of the Subscribed 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 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;

 

    	 	12	 

     

    

 

		(6)	Notwithstanding anything to the contrary set forth herein, the Company shall not, when so advising
the Subscribers of such events, provide the Subscribers with any material, nonpublic information regarding the Company.

  

(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 Company is permitted hereunder to suspend, and has
suspended, the use of a prospectus forming part of a Registration Statement, the Company 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 Subscribed
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 Subscribed Shares to be listed on each securities exchange or market, if any, on which
equity securities issued by the Company have been listed;

 

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

 

    	 	13	 

     

    

 

d. Notwithstanding
anything to the contrary in this Subscription Agreement, the Company shall be entitled to delay or postpone the effectiveness of
the Registration Statement, and from time to time to require any Subscriber not to sell under the Registration Statement or to
suspend the effectiveness thereof, if the negotiation or consummation of a transaction by the Company or its subsidiaries is pending
or an event has occurred, which negotiation, consummation or event the Company’s board of directors reasonably believes,
upon the advice of legal counsel, would require additional disclosure by the Company in the Registration Statement of material
information that the Company 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 Company’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 Company 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 Company 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, each Subscriber agrees that (i) it will immediately discontinue offers and sales of the Subscribed
Shares under the Registration Statement (excluding, for the avoidance of doubt, sales conducted pursuant to Rule 144) until such
Subscriber receives copies of a supplemental or amended prospectus (which the Company 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 Company 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 Company unless otherwise required by law or subpoena. If so
directed by the Company, each Subscriber will deliver to the Company or, in such Subscriber’s sole discretion destroy, all
copies of the prospectus covering the Subscribed Shares in such Subscriber’s possession; provided, however, that this obligation
to deliver or destroy all copies of the prospectus covering the Subscribed Shares shall not apply (i) to the extent such 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. Any Subscriber
may deliver written notice (including via email in accordance with Section 8(l)) (an “Opt-Out Notice”) to the
Company requesting that such Subscriber not receive notices from the Company otherwise required by this Section 5; provided, however,
that such Subscriber may later revoke any such Opt-Out Notice in writing. Following receipt of an Opt-Out Notice from a Subscriber
(unless subsequently revoked), (i) the Company shall not deliver any such notices to that Subscriber and such Subscriber shall
no longer be entitled to the rights associated with any such notice and (ii) each time prior to such Subscriber’s intended
use of an effective Registration Statement, such Subscriber will notify the Company 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 Company will so notify such Subscriber,
within one (1) Business Day of such Subscriber’s notification to the Company, by delivering to such Subscriber a copy of
such previous notice of Suspension Event, and thereafter will provide such Subscriber with the related notice of the conclusion
of such Suspension Event immediately upon its availability.

f. The Company
shall, notwithstanding any termination of this Subscription Agreement, indemnify, defend and hold harmless each Subscriber (to
the extent a seller under the Registration Statement), the officers, directors, agents, partners, members, managers, stockholders,
affiliates, employees and investment advisers of each of them, each person who controls such Subscriber (within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act) and the officers, directors, partners, members, managers,
stockholders, agents, affiliates, employees and investment advisers of each such controlling person, to the fullest extent permitted
by applicable law, from and against any and all losses, claims, damages, liabilities, costs (including, without limitation, reasonable
attorneys’ fees) and expenses (collectively, “Losses”), as incurred, that arise out of or are based upon
(i) any untrue or alleged untrue statement of a material fact contained in the Registration Statement, any prospectus included
in the Registration Statement or any form of prospectus or in any amendment or supplement thereto or in any preliminary prospectus,
or arising out of or relating to any omission or alleged omission to state a material fact required to be stated therein or necessary
to make the statements therein (in the case of any prospectus or form of prospectus or supplement thereto, in light of the circumstances
under which they were made) not misleading, or (ii) any violation or alleged violation by the Company of the Securities Act,
Exchange Act or any state securities law or any rule or regulation thereunder, in connection with the performance of its obligations
under this Section 5, except to the extent, but only to the extent, that such untrue statements, alleged untrue statements,
omissions or alleged omissions are based upon information regarding such Subscriber furnished in writing to the Company by such
Subscriber expressly for use therein. The Company shall notify such Subscriber promptly of the institution, threat or assertion
of any proceeding arising from or in connection with the transactions contemplated by this Section 5 of which the Company
is aware. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of an indemnified
party and shall survive the transfer of the Subscribed Shares by such Subscriber.

 

g. Each
Subscriber shall, severally and not jointly, indemnify and hold harmless the Company, its directors, officers, agents and employees,
each person who controls the Company (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange
Act), and the directors, officers, agents or employees of such controlling persons, to the fullest extent permitted by applicable
law, from and against all Losses, as incurred, arising out of or are based upon any untrue or alleged untrue statement of a material
fact contained in any Registration Statement, any prospectus included in the Registration Statement, or any form of prospectus,
or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged
omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus,
or any form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading to the
extent, but only to the extent, that such untrue statements or omissions are based upon information regarding such Subscriber furnished
in writing to the Company by such Subscriber expressly for use therein. In no event shall the liability of any Subscriber be greater
in amount than the dollar amount of the net proceeds received by such Subscriber upon the sale of the Subscribed Shares giving
rise to such indemnification obligation.

 

h. No Subscriber
shall execute any short sales or engage in other hedging transactions of any kind with respect to securities of the Company during
the period from the date of the Closing through the date that is 45 consecutive days thereafter.

 

    	 	15	 

     

    

 

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 Transaction Agreement is terminated in accordance with its terms, (b) upon
the mutual written agreement of the Company and each Subscriber to terminate this Subscription Agreement, or (c) if, on the
Closing Date of the Transaction, any of the conditions to Closing set forth in Section 2 of this Subscription Agreement have
not been satisfied as of the time required hereunder to be so satisfied or waived by the party entitled to grant such waiver and,
as a result thereof, the transactions contemplated by this Subscription Agreement are not consummated; 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 Company
shall notify each Subscriber of the termination of the Transaction Agreement promptly after the termination thereof.

 

7. Trust Account
Waiver. Each Subscriber acknowledges that the Company is a blank check company with the powers and privileges to effect a merger,
asset acquisition, reorganization or similar business combination involving the Company and one or more businesses or assets. Each
Subscriber further acknowledges that, as described in the Company’s prospectus relating to its initial public offering dated
November 2, 2017 (the “Prospectus”) available at www.sec.gov, substantially all of the Company’s assets
consist of the cash proceeds of the Company’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 Company,
its public stockholders and the underwriters of the Company’s initial public offering. Except with respect to interest earned
on the funds held in the Trust Account that may be released to the Company 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 Company entering
into this Subscription Agreement, the receipt and sufficiency of which are hereby acknowledged, each Subscriber, solely on behalf
of itself and its officers, directors and affiliates, hereby irrevocably waives any and all right, title and interest, or any claim
of any kind they have or may have in the future, 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. All notices,
requests, demands, claims, and other communications hereunder shall be in writing. Any notice, request, demand, claim, or other

b. Each

representations and warranties contained in this Subscription Agreement. Prior to the Closing, each Subscriber agrees to promptly
notify the Company if it becomes aware that any of the acknowledgments, understandings, agreements, representations and warranties
of such Subscriber set forth herein are no longer accurate in all material respects. The Company acknowledges that each Subscriber
and others will rely on the acknowledgments, understandings, agreements, representations and warranties contained in this Subscription
Agreement. Prior to the Closing, the Company agrees to promptly notify each Subscriber if it becomes aware that any of the acknowledgments,
understandings, agreements, representations and warranties of the Company set forth herein are no longer accurate in all material
respects.

 

    	 	16	 

     

    

 

c. Each
of the Company and the Subscribers 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.

 

d. Neither
this Subscription Agreement nor any rights that may accrue to the Subscribers hereunder (other than the Subscribed Shares acquired
hereunder, if any) may be transferred or assigned. Neither this Subscription Agreement nor any rights that may accrue to the Company
hereunder may be transferred or assigned, provided, that, for the avoidance of doubt, the completion of the Domestication shall
not be deemed a transfer or assignment by the Company.

 

e. All the
agreements, representations and warranties made by each party hereto in this Subscription Agreement shall survive the Closing.

 

f. The Company
may request from any Subscriber such additional information as the Company may deem necessary to evaluate the eligibility of such
Subscriber to acquire the Subscribed Shares, and such 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.

 

g. 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.

 

h. No provision
of this Subscription Agreement may be amended, modified or waived without the prior written consent of Strike if such amendment,
modification or waiver (i) reduces the number of Subscribed Shares, the Per Share Price or the Purchase Price, (ii) imposes new
or additional conditions or otherwise expands, amends or modifies any of the conditions to the Closing in a manner that would reasonably
be expected to (x) materially impair or delay the Closing (or satisfaction of the conditions to the Closing) or (z) adversely affect
the ability of the Company to enforce its rights against under this Subscription Agreement or any of the other definitive agreements
with respect thereto or (iii) adds or changes in any material respect any economic or other rights or benefits granted to any Subscriber
hereunder in respect of the Subscribed Shares.

 

i. 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. This Subscription Agreement
shall not confer any rights or remedies upon any person other than (i) the parties hereto and their respective successor and assigns
and (ii) the persons entitled to indemnification under Section 5 hereof.

 

    	 	17	 

     

    

 

j. 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.

 

k. 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.

 

l. This
Subscription Agreement may be executed and delivered in one or more counterparts (including by facsimile or electronic mail or
in .pdf) and by different parties in separate counterparts, with the same effect as if all parties hereto had signed the same document.
All counterparts so executed and delivered shall be construed together and shall constitute one and the same agreement.

 

m. The Placement
Agent shall be a third party beneficiary of the representations and warranties of the Company set forth in Section 3 hereof and
with respect to the representations and warranties of Subscriber set forth in Section 4(h) and 4(i) hereof. This Subscription Agreement
is intended for the benefit of the parties hereto and their respective successors and permitted assigns and is not for the benefit
of, nor may any provision hereof be enforced by, any other person, except as otherwise set forth in this Section 8(m).

 

n. The parties
hereto agree that irreparable damage would occur in the event that any of the provisions of this Subscription Agreement were not
performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be
entitled to an injunction or injunctions to prevent breaches of this Subscription Agreement and to enforce specifically the terms
and provisions of this Subscription Agreement, this being in addition to any other remedy to which such party is entitled at law,
in equity, in contract, in tort or otherwise.

 

o. This
Subscription Agreement shall be governed by, and construed in accordance with, the laws of the state of Delaware, without regard
to the principles of conflicts of laws that would otherwise require the application of the law of any other state.

 

p. EACH
PARTY HEREBY WAIVES THEIR RESPECTIVE RIGHTS TO A TRIAL BY JURY OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OR RELATED
TO THIS SUBSCRIPTION AGREEMENT IN ANY ACTION, PROCEEDING OR OTHER LITIGATION OF ANY TYPE BROUGHT BY ANY PARTY AGAINST ANY OTHER
PARTY OR ANY AFFILIATE OF ANY OTHER SUCH PARTY, WHETHER WITH RESPECT TO CONTRACT CLAIMS, TORT CLAIMS OR OTHERWISE. THE PARTIES
AGREE THAT ANY SUCH CLAIM OR CAUSE OF ACTION SHALL BE TRIED BY A COURT TRIAL WITHOUT A JURY. WITHOUT LIMITING THE FOREGOING, THE
PARTIES FURTHER AGREE THAT THEIR RESPECTIVE RIGHT TO A TRIAL BY JURY IS WAIVED BY OPERATION OF THIS SECTION AS TO ANY ACTION, COUNTERCLAIM
OR OTHER PROCEEDING WHICH SEEKS, IN WHOLE OR IN PART, TO CHALLENGE THE VALIDITY OR ENFORCEABILITY OF THIS SUBSCRIPTION AGREEMENT
OR ANY PROVISION HEREOF. THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS SUBSCRIPTION
AGREEMENT.

 

    	 	18	 

     

    

 

q. The parties
agree that all disputes, legal actions, suits and proceedings arising out of or relating to this Subscription Agreement must be
brought exclusively in the Court of Chancery of the state of Delaware and any state appellate court therefrom within the state
of Delaware (or, if the Court of Chancery of the state of Delaware declines to accept jurisdiction over a particular matter, any
federal court within the state of Delaware or, in the event each federal court within the state of Delaware declines to accept
jurisdiction over a particular matter, any state court within the state of Delaware) (collectively the “Designated Courts”).
Each party hereby consents and submits to the exclusive jurisdiction of the Designated Courts. No legal action, suit or proceeding
with respect to this subscription agreement may be brought in any other forum. Each party hereby irrevocably waives all claims
of immunity from jurisdiction and any objection which such party may now or hereafter have to the laying of venue of any suit,
action or proceeding in any Designated Court, including any right to object on the basis that any dispute, action, suit or proceeding
brought in the Designated Courts has been brought in an improper or inconvenient forum or venue. Each of the parties also agrees
that delivery of any process, summons, notice or document to a party hereof in compliance with section 8(a) of this Subscription
Agreement shall be effective service of process for any action, suit or proceeding in a Designated Court with respect to any matters
to which the parties have submitted to jurisdiction as set forth above.
