the Issuer, nor any person acting on its behalf has, directly or indirectly, made any offers or sales of any Issuer security or
solicited any offers to buy any security under circumstances that would adversely affect reliance by the Issuer on Section 4(a)(2)
of the Securities Act for the exemption from registration for the transactions contemplated hereby or would require registration
of the issuance of the Shares under the Securities Act.


 


2.2.11 The
Issuer has not entered into any subscription agreement, side letter or similar agreement with any Other Subscriber or any other
investor in connection with such Other Subscriber’s or investor’s direct or indirect investment in the Issuer other
than the Other Subscription Agreements. The Other Subscription Agreements reflect the same per share purchase price as this Subscription
Agreement and do not include terms or conditions that are more advantageous to any Other Subscriber or any other investor compared
to the terms and conditions of the Subscriber as set forth in this Subscription Agreement and the Other Subscription Agreements
shall not be amended after the date hereof to provide for terms with respect to the purchase of shares that are more favorable
to such Other Subscriber or such other investor thereunder than the terms of this Subscription Agreement, unless such terms are
also offered to the Subscriber.


 


2.2.12 As
of the date hereof, the Existing Class A Shares are registered pursuant to Section 12(b) of the Exchange Act, and are listed for
trading on the NYSE under the symbol “DFNS.” There is no suit, action, proceeding or investigation pending or, to the
knowledge of the Issuer, threatened against the Issuer by the NYSE or the Commission with respect to any intention by such entity
to deregister the Existing Class A Shares or prohibit or terminate the listing of the Existing Class A Shares on the NYSE excluding,
for the purposes of clarity, the customary ongoing review by the NYSE of the Issuer’s listing application with respect to
the Shares in connection with the Transactions. The Issuer has taken no action that is designed to terminate the registration of
the Existing Class A Shares under the Exchange Act. Upon consummation of the Transactions, the issued and outstanding Class A common
stock, including the Shares, will be registered pursuant to Section 12(b) of the Exchange Act and will be listed for trading on
the NYSE. The Issuer has taken no action that is designed to terminate the registration of the Class A common stock of the Issuer
under the Exchange Act or the listing of the Class A common stock of the Issuer on the NYSE.


 






    -11-


     


    

 


2.2.13 The
Issuer is in compliance with all applicable laws, except where such noncompliance would not reasonably be expected to have an Issuer
Material Adverse Effect. As of the date hereof, the Issuer has not received any written communication from a governmental authority
that alleges that the Issuer is not in compliance with or is in default or violation of any applicable law, except where such non-compliance,
default or violation would not reasonably be expected to have, individually or in the aggregate, an Issuer Material Adverse Effect.


 


2.2.14 Except
for such matters as have not had and would not be reasonably likely to have an Issuer Material Adverse Effect, there is no (i)
suit, action, claim or other proceeding or arbitration before a governmental authority or arbitrator pending, or, to the knowledge
of the Issuer, threatened in writing against the Issuer or (ii) judgment, decree, injunction, ruling or order of any governmental
authority or arbitrator outstanding against the Issuer or any of its subsidiaries.


 


2.2.15 The
Issuer acknowledges and agrees that, notwithstanding anything herein to the contrary, the Shares may be pledged by the Subscriber
in connection with a bona fide margin agreement, provided such pledge shall be (i) pursuant to an available exemption from the
registration requirements of the Securities Act or (ii) pursuant to, and in accordance with, a registration statement that is effective
under the Securities Act at the time of such pledge, and Subscriber effecting a pledge of Shares shall not be required to provide
the Issuer with any notice thereof; provided, however, that neither the Issuer or their counsel shall be required to take any action
(or refrain from taking any action) in connection with any such pledge, other than providing any such lender of such margin agreement
with an acknowledgment that the Shares are not subject to any contractual prohibition on pledging or lock up, the form of such
acknowledgment to be subject to review and comment by the Issuer in all respects.


 


2.2.16 The
Issuer is not, and immediately after receipt of payment for the Shares and consummation of the Transactions, will not be, an “investment
company” within the meaning of the Investment Company Act of 1940, as amended.

3. Settlement
Date and Delivery.


 


3.1 Closing.
The closing of the Subscription contemplated hereby (the “Closing”) shall occur on the date of (the “Closing
Date”), and immediately prior to, the consummation of the Transactions. Upon written notice from (or on behalf of) the
Issuer to Subscriber (the “Closing Notice”) at least five (5) Business Days prior to the date (the “Expected
Date”) that the Issuer reasonably expects all conditions to the closing of the Transactions to be satisfied, Subscriber
shall deliver to the Issuer at least two (2) Business Days prior to the Closing Date, the Purchase Price for the Shares, by wire
transfer of United States dollars in immediately available funds to the account specified by the Issuer in the Closing Notice,
such funds to be held by the Issuer in escrow until the Closing. At the Closing, upon satisfaction (or, if applicable, waiver)
of the conditions set forth in this Section 3, the Issuer shall deliver to Subscriber (i) the Shares in book entry form,
free and clear of any liens or other restrictions (other than those arising under this Subscription Agreement or applicable securities
laws), in the name of Subscriber (or its nominee in accordance with its delivery instructions) or to a custodian designated by
Subscriber, as applicable and (ii) as promptly as practicable after the Closing, evidence from the Issuer's transfer agent of the
issuance to Subscriber of the Shares on and as of the Closing Date. In the event the Closing does not occur within two (2) Business
Days of the Expected Date, the Issuer will return the Purchase Price to the Subscriber within three (3) Business Days of the Expected
Date by wire transfer of immediately available funds to an account specified by Subscriber (the “Purchase Price Return”).
Notwithstanding the foregoing two sentences, for any Subscriber that informs the Issuer (1) that it is an investment company registered
under the Investment Company Act of 1940, as amended, (2) that it is advised by an investment adviser subject to regulation under
the Investment Advisers Act of 1940, as amended, or (3) that its internal compliance policies and procedures so require it, then,
in lieu of the settlement procedures in the foregoing two sentences, the following shall apply: such Subscriber shall deliver on
the Closing Date the Purchase Price for the Shares by wire transfer of United States dollars in immediately available funds to
the account specified by the Issuer in the Closing Notice against delivery by the Issuer to Subscriber of the Shares in book entry
form, free and clear of any liens or other restrictions (other than those arising under this Subscription Agreement or applicable
securities laws), in the name of Subscriber (or its nominee in accordance with its delivery instructions) and evidence from the
Company’s transfer agent of the issuance to Subscriber of the Shares on and as of the Closing Date, and shall use commercially
reasonable efforts to deliver the Purchase Price at or prior to 10:00 a.m. New York City time (or as soon as practicable following
receipt of evidence from the Issuer’s transfer agent of the issuance to Subscriber of the Shares on and as of the Closing
Date) on the Closing Date. Notwithstanding the Purchase Price Return (x) a failure to close on the Expected Date shall not, by
itself, be deemed to be a failure of any of the conditions to Closing set forth in this Section 3 to be satisfied or waived
on or prior to the Closing Date, and (y) unless and until this Subscription Agreement is terminated in accordance with Section
6 hereof, Subscriber shall remain obligated (A) to redeliver funds to the Issuer in escrow (or on the new Closing Date as specified
above) following the Issuer’s delivery to Subscriber of a new Closing Notice and (B) to consummate the Closing upon satisfaction
of the conditions set forth in this Section 3. “Business Day” means any day other than a Saturday, Sunday
or any other day on which commercial banks are required or authorized to close in the State of New York. Any funds held in escrow
by the Issuer will be uninvested, and the Subscriber shall not be entitled to any interest earned thereon. Upon delivery of the
Shares to Subscriber (or its nominee or custodian, if applicable), the Purchase Price may be released by the Issuer from escrow.

as to materiality or Subscriber Material Adverse Effect, which representations and warranties shall be true and correct in all
respects) on and as of the Closing Date (unless they specifically speak as of another date in which case they shall be true and
correct in all material respects as of such date) (other than representations and warranties that are qualified as to materiality
or Subscriber Material Adverse Effect, which representations and warranties shall be true and correct in all respects), with the
same force and effect as if they had been made on and as of said date, but in each case without giving effect to consummation of
the Transactions and consummation of the Closing shall constitute a reaffirmation by the Subscriber of such representations and
warranties.


 


3.2.2 Conditions
to the Transactions. All conditions precedent to the closing of the Transactions set forth in the Merger Agreement, including
the approval of the Issuer's stockholders, shall have been satisfied (as determined by the parties to the Merger Agreement) or

the Merger Agreement).


 


3.2.3 Closing
of the Transactions. The Transactions set forth in the Merger Agreement shall have been or will be consummated substantially
concurrently with the Closing.

or prohibition.


 


3.2.5 Performance
and Compliance under Subscription Agreement. Subscriber shall have performed, satisfied and complied in all material respects
with all covenants, agreements and conditions required by this Subscription Agreement to be performed, satisfied or complied with
by it at or prior to the Closing, except where the failure of such performance or compliance would not or would not reasonably
be expected to prevent, materially delay, or materially impair the ability of the Issuer to consummate the closing of the Transactions.

3.3.1 Representations
and Warranties Correct. The representations and warranties made by the Issuer in Section 2.2 hereof shall be true and
correct in all material respects (other than representations and warranties that are qualified as to materiality or Issuer Material
Adverse Effect, which representations and warranties shall be true and correct in all respects) on and as of the Closing Date (unless
they specifically speak as of another date in which case they shall be true and correct in all material respects (other than representations
and warranties that are qualified as to materiality or Issuer Material Adverse Effect, which representations and warranties shall
be true and correct in all respects) as of such date), with the same force and effect as if they had been made on and as of said
date, but in each case without giving effect to consummation of the Transactions, and consummation of the Closing shall constitute
a reaffirmation by the Issuer of such representations and warranties.


 


3.3.2 Conditions
to the Transactions. All conditions precedent to the closing of the Transactions set forth in the Merger Agreement, including
the approval of the Issuer's stockholders, shall have been satisfied (as determined by the parties to the Merger Agreement) or

or prohibition.


 


3.3.5 Timing.
The Closing (as defined in the Merger Agreement as in effect on the date hereof) shall have occurred on or before the Termination
Date (as defined in the Merger Agreement without giving effect to any amendment, modification or waiver of the Merger Agreement

of the Transactions.


 


3.3.8 No
Amendment. No amendment, modification or waiver of the Merger Agreement shall have occurred that would reasonably be expected
to materially and adversely affect the economic benefits that Subscriber or the Issuer would reasonably expect to receive under

    -15-


     


    

 


3.3.9 Consents.
All consents, waivers, authorizations or orders of, any notice required to be made to, and any filing or registration with, any
court or other federal, state, local or other governmental authority, self-regulatory organization (including the NYSE and any
stockholder approval required by the rules and regulations of the NYSE) or other person in connection with the execution, delivery
and performance of this Subscription Agreement (including, without limitation, the issuance of the Shares) required to be made
in connection with the issuance and sale of the Shares shall have been obtained or made, except where the failure to so obtain
or make would not prevent the Issuer from consummating the transactions contemplated hereby, including the issuance and sale of
the Shares.


 


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


 


4. Registration
Statement.


 


4.1 The
Issuer agrees that, within thirty (30) calendar days following the Closing Date (the “Filing Date”), the Issuer
will file with the Commission (at the Issuer’s sole cost and expense) a registration statement registering the resale of
the Shares (including any related prospectus, the “Registration Statement”), and the Issuer shall use its commercially
reasonable efforts to have the Registration Statement declared effective as soon as practicable after the filing thereof, but no
later than the earlier of (i) the 60th calendar day (or 120th calendar day if the Commission notifies the
Issuer that it will “review” the Registration Statement) following the Closing Date and (ii) the 5th Business
Day after the date the Issuer is notified (orally or in writing, whichever is earlier) by the Commission that the Registration
Statement will not be “reviewed” or will not be subject to further review (such earlier date, the “Effectiveness
Date”); provided, however, that the Issuer’s obligations to include such Shares in the Registration
Statement are contingent upon Subscriber furnishing in writing to the Issuer such information regarding Subscriber and its affiliates,
and the intended method of disposition of the Shares as shall be reasonably requested by the Issuer to effect the registration
of the Shares, and Subscriber and such affiliates shall execute such documents in connection with such registration as the Issuer
may reasonably request that are customary of a selling stockholder in similar situations; provided, further, that
Subscriber shall not in connection with the foregoing be required to execute any lock-up or similar agreement or otherwise be subject
to any contractual restriction on the ability to transfer the Shares. Notwithstanding the foregoing, if the Commission prevents
the Issuer from including any or all of the Shares proposed to be registered under the Registration Statement due to limitations
on the use of Rule 415 under the Securities Act for the resale of the Shares pursuant to this Section 4 by the applicable stockholders
or otherwise, such Registration Statement shall register for resale such number of Shares which is equal to the maximum number
of Shares as is permitted to be registered by the Commission. In such event, the number of Shares to be registered for each selling
stockholder named in the Registration Statement shall be reduced pro rata among all selling stockholders based on the number of
Shares included in the Registration Statement by each selling stockholder. For purposes of clarification, any failure by the Issuer
to file the Registration Statement by the Filing Date or to effect such Registration Statement by the Effectiveness Date shall
not otherwise relieve the Issuer of its obligations to file or effect the Registration Statement as set forth above in this Section
4. In the case of the registration effected by the Issuer pursuant to this Subscription Agreement, the Issuer shall, upon reasonable
request, inform Subscriber as to the status of such registration. Subscriber shall not be entitled to use the Registration Statement
for an underwritten offering of Shares. The Issuer will use its commercially reasonable efforts to provide a draft of the Registration
Statement to the Subscriber for review at least two (2) Business Days in advance of filing the Registration Statement; provided
that, for the avoidance of doubt, in no event shall the Issuer be required to delay or postpone the filing of such Registration
Statement as a result of or in connection with Subscriber’s review. In no event shall the Subscriber be identified as a statutory
underwriter in the Registration Statement unless requested by the Commission; provided, that if the Commission requests that Subscriber
be identified as a statutory underwriter in the Registration Statement, Subscriber will have the option, in its sole and absolute
discretion, to either (i) have the opportunity to withdraw from the Registration Statement upon its prompt written request to the
Issuer, in which case the Issuer's obligation to register the Shares will be deemed satisfied or (ii) be included as such in the
Registration Statement. Notwithstanding anything to the contrary contained herein, the Issuer may delay or postpone filing of the
Registration Statement, and from time to time require Subscriber not to sell under the Registration Statement or suspend the use
or effectiveness of the Registration Statement if it determines that (i) in order for the Registration Statement to not contain
a material misstatement or omission, an amendment thereto would be needed to include information that would at that time not otherwise
be required in a current, quarterly or annual report under the Exchange Act, (ii) the negotiation or consummation of a bona fide
business or financing transaction by the Issuer or its subsidiaries is pending or an event has occurred, which negotiation, consummation
or event Issuer’s board of directors reasonably believes would require additional disclosure by Issuer in the Registration
Statement of material information that Issuer has a bona fide business purpose for keeping confidential and the non-disclosure
of which in the Registration Statement would be expected, in the reasonable determination of Issuer’s board of directors
to cause the Registration Statement to fail to comply with applicable disclosure requirements, or (iii) in the good faith judgment
of Issuer’s board of directors, such filing or effectiveness or use of such Registration Statement would be seriously detrimental
to Issuer and Issuer’s board of directors concludes as a result that it is essential to defer such filing (each such circumstance,
a “Suspension Event”); provided, however, that the Issuer may not delay or suspend the Registration Statement
on more than two occasions or for more than sixty (60) consecutive calendar days, or more than one hundred and twenty (120) total
calendar days, in each case during any twelve-month period, and (x) the Issuer shall use commercially reasonable efforts to make
the Registration Statement available for the sale by the Subscriber of such securities as soon as practicable thereafter. Subscriber
acknowledges and agrees that the Registration Statement may include shares of Class A common stock held by (i) Other Subscribers
and (ii) affiliates of the Issuer or the Company.

4.2 Upon
receipt of any written notice from the Issuer (which notice shall not contain any material non-public information regarding the
Issuer) of the happening of any Suspension Event during the period that the Registration Statement is effective or if as a result
of a Suspension Event the Registration Statement or related prospectus contains any untrue statement of a material fact or omits
to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances
under which they were made (in the case of the prospectus) not misleading, the Subscriber agrees that (i) it will immediately discontinue
offers and sales of the Shares under the Registration Statement until the Subscriber receives copies of a supplemental or amended
prospectus (which the Issuer agrees to prepare as soon as practicable) that corrects the misstatement(s) or omission(s) referred
to above and receives notice that any post-effective amendment has become effective or unless otherwise notified by the Issuer
that it may resume such offers and sales, and (ii) it will maintain the confidentiality of any information included in such written
notice delivered by the Issuer unless otherwise required by law, subpoena or regulatory request or requirement. If so directed
by the Issuer, the Subscriber will deliver to the Issuer or, in the Subscriber’s sole discretion destroy, all copies of the
prospectus covering the Shares in the Subscriber’s possession; provided, however, that this obligation to deliver or destroy
all copies of the prospectus covering the Shares shall not apply (w) 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 (x) to copies stored electronically on archival servers
as a result of automatic data back-up. Notwithstanding anything to the contrary, the Issuer shall use commercially reasonable efforts
to cause its transfer agent to deliver unlegended Shares to a transferee of the Subscriber in connection with any sale of Shares
pursuant to the Registration Statement with respect to which the Subscriber has entered into a contract for sale, prior to the
Subscriber’s receipt of the notice of a Suspension Event and for which the Subscriber has not yet settled.


 


4.3 At
its own expense, the Issuer shall:


 


4.3.1 other
than during a Suspension Event, use its commercially reasonable efforts to keep such registration continuously effective with respect
to Subscriber, and to keep the Registration Statement or any subsequent shelf registration statement free of any material misstatements
or omissions, until the earlier of the following: (i) Subscriber ceases to hold any Shares, (ii) the date all Shares held by Subscriber
may be sold without restriction under Rule 144, including without limitation, any volume and manner of sale restrictions which
may be applicable to affiliates under Rule 144 and without the requirement for the Issuer to be in compliance with the current
public information required under Rule 144(c)(1) (or Rule 144(i)(2), if applicable), and (iii) three years from the Effectiveness
Date of the Registration Statement;


 


4.3.2 advise
Subscriber within five (5) Business Days:


 


(a) when
a Registration Statement or any post-effective amendment thereto has been filed with the Commission and has become effective;


 


(b) 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;


 






    -17-


     


    

 


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


 


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


 


Notwithstanding anything
to the contrary set forth herein, the Issuer shall not, when so advising Subscriber of such events, provide Subscriber with any
material, nonpublic information regarding the Issuer;


 


4.3.3 use
its commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of any Registration Statement
as soon as reasonably practicable;


 


4.3.4 upon
the occurrence of any event contemplated in Section 4.3.2(d), except during a Suspension Event, the Issuer shall use its
commercially reasonable efforts to as soon as reasonably practicable prepare a post-effective amendment to such Registration Statement
or a supplement to the related prospectus, or file any other required document so that, as thereafter delivered to purchasers of
the 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;


 


4.3.5 for
so long as Subscriber holds Shares, use its commercially reasonable efforts to:


 


(a) make
and keep public information available (as those terms are understood and defined in Rule 144) and file with the Commission in a
timely manner all reports and other documents required of the Issuer under the Exchange Act so long as the Issuer remains subject
to such requirements to enable the Subscriber to resell the Shares pursuant to Rule 144;


 


(b) furnish
to Subscriber so long as it owns Shares, as promptly as practicable upon request, (x) a written statement by the Issuer, if true,
that it has complied with the reporting requirements of the Exchange Act, and (y) such other information as may be reasonably requested
to permit Subscriber to sell its Shares pursuant to Rule 144 without registration;


 






    -18-


     


    

 


(c) (i)
cause the removal of all Restricted Legends from any Shares being sold under the Registration Statement or pursuant to Rule 144
at the time of sale of such Shares and, at the request of Holder (as defined below), (ii) cause the removal of all Restricted Legends
from any Shares held by such Holder that may be sold by such Holder without restriction under Rule 144, including without limitation,
any volume, manner of sale and current public information required by Rule 144(c)(1) and Rule 144(i)(2), if applicable, and (iii)
cause its legal counsel to deliver the necessary legal opinions, if any, as reasonably requested by the transfer agent to effect
the removal of Restricted Legends in connection with sales pursuant to the foregoing clause (i) or the removal of Restricted Legends
pursuant to the foregoing clause (ii) upon the receipt of such supporting documentation, if any, as reasonably requested by such
legal counsel. “Holder” shall mean the Subscriber or any affiliate of the Subscriber to which the rights
under this Section 4 shall have been assigned.


 


4.3.6
use its commercially reasonable efforts to cause all Shares to be listed on each securities exchange or market, if any, on which
the Class A common stock is then listed.


 


4.4 Indemnification.


 


4.4.1 The
Issuer shall, notwithstanding any termination of this Subscription Agreement, indemnify, defend and hold harmless Subscriber, the
officers, directors, members, managers, partners, agents and employees of Subscriber, each person who controls Subscriber (within
the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) and the officers, directors, members, managers,
partners, agents, affiliates and employees 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 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, except to the extent that untrue statements, alleged untrue statements, omissions
or alleged omissions are based upon information regarding Subscriber furnished in writing to the Issuer by Subscriber expressly
for use therein. Notwithstanding the foregoing, the Issuer's indemnification obligations shall not apply to amounts paid in settlement
of any Losses or action if such settlement is effected without the prior written consent of the Issuer (which consent shall not
be unreasonably withheld, conditioned or delayed).


 






    -19-


     


    

 


4.4.2 Subscriber
shall, severally and not jointly with any Other Subscriber, indemnify and hold harmless the Issuer, its directors, officers, agents
and employees, each person who controls the Issuer (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 arising out of or 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, alleged untrue statements, omissions or alleged omissions are based
upon information regarding Subscriber furnished in writing to the Issuer by Subscriber expressly for use therein. In no event shall
the liability of Subscriber be greater in amount than the dollar amount of the net proceeds received by Subscriber upon the sale
of the Shares giving rise to such indemnification obligation. Notwithstanding the foregoing, Subscriber’s indemnification
obligations shall not apply to amounts paid in settlement of any Losses or action if such settlement is effected without the prior
written consent of Subscriber (which consent shall not be unreasonably withheld, conditioned or delayed).


 


4.4.3 Any
person or entity entitled to indemnification herein shall (i) give prompt written notice to the indemnifying party of any claim
with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any person’s
or entity’s right to indemnification hereunder to the extent such failure has not prejudiced the indemnifying party) and
(ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying
parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably
satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability
for any settlement made by the indemnified party without its consent (but such consent shall not be unreasonably withheld, conditioned
or delayed). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated
to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such
claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party
and any other of such indemnified parties with respect to such claim. No indemnifying party shall, without the consent of the indemnified
party, consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment
of money (and such money is so paid by the indemnifying party pursuant to the terms of such settlement), which settlement includes
a statement or admission of fault and culpability on the part of such indemnified party, and does not include as an unconditional
term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such
claim or litigation.


 


4.4.4 The
indemnification provided for under this Subscription Agreement shall remain in full force and effect regardless of any investigation
made by or on behalf of the indemnified party or any officer, director or controlling person or entity of such indemnified party
and shall survive the transfer of securities.

4.4.5 If
the indemnification provided under this Section 4.4 from the indemnifying party is unavailable or insufficient to hold harmless
an indemnified party in respect of any Losses referred to herein, then the indemnifying party, in lieu of indemnifying the indemnified
party, shall contribute to the amount paid or payable by the indemnified party as a result of such Losses in such proportion as
is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well as any other relevant
equitable considerations; provided, however, that the liability of the Subscriber shall be limited to the net proceeds received
by such Subscriber from the sale of Shares giving rise to such indemnification obligation. The relative fault of the indemnifying
party and indemnified party shall be determined by reference to, among other things, whether any action in question, including
any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, was made by
(or not made by, in the case of an omission), or relates to information supplied by (or not supplied by, in the case of an omission),
such indemnifying party or indemnified party, and the indemnifying party’s and indemnified party’s relative intent,
knowledge, access to information and opportunity to correct or prevent such action. The amount paid or payable by a party as a
result of the Losses shall be deemed to include, subject to the limitations set forth in this Section 4.4, any legal or other fees,
charges or expenses reasonably incurred by such party in connection with any investigation or proceeding. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this
Section 4.4.5 from any person or entity who was not guilty of such fraudulent misrepresentation.


 


4.4.6 For
purposes of this Section 4 of this Subscription Agreement, (i) “Shares” shall mean, as of any date of determination,
the Shares (as defined in the recitals to this Subscription Agreement) and any other equity security issued or issuable with respect
to the Shares by way of share split, dividend, distribution, recapitalization, merger, exchange, or replacement or similar event
or otherwise, and (ii) “Subscriber” shall include any affiliate of the Subscriber to which the rights under this Section
4 shall have been duly assigned.


 


5. Additional
Subscriber Agreement Regarding Short Sales. The Subscriber hereby agrees that, from the date of this Subscription Agreement,
none of Subscriber, its controlled affiliates, or any person or entity acting on behalf of Subscriber or any of its controlled
affiliates or pursuant to any understanding with Subscriber or any of its controlled affiliates will engage in any Short Sales
with respect to securities of Issuer prior to the Closing. For purposes of this Section 5, “Short Sales” shall include,
without limitation, all “short sales” as defined in Rule 200 promulgated under Regulation SHO under the Exchange Act,
and all types of direct and indirect stock pledges (other than pledges in the ordinary course of business as part of prime brokerage
arrangements), forward sale contracts, options, puts, calls, swaps and similar arrangements (including on a total return basis),
and sales and other transactions through non-U.S. broker dealers or foreign regulated brokers. Notwithstanding the foregoing, (i)
nothing herein shall prohibit other entities under common management with the Subscriber that have no knowledge of this Subscription
Agreement or of the Subscriber’s participation in the Transaction (including the Subscriber’s controlled affiliates
and/or affiliates) from entering into any Short Sales, (ii) in the case of a Subscriber that is a multi-managed investment vehicle
whereby separate portfolio managers manage separate portions of such Subscriber’s assets and the portfolio managers have
no knowledge of the investment decisions made by the portfolio managers managing other portions of such Subscriber’s assets,
this Section 5 shall only apply with respect to the portion of assets managed by the portfolio manager that made the investment
decision to purchase the Subscription Amount covered by this Subscription Agreement and (iii) nothing herein shall prohibit such
persons from engaging in hedging transactions with respect to securities of the Issuer acquired after the day hereof in open market
purchases, so long as such person does not create 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 Shares”.

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 (i) such date and time as the Merger Agreement is validly terminated in accordance with its terms, (ii) upon the mutual
written agreement of each of the parties hereto to terminate this Subscription Agreement, (iii) if any of the conditions to Closing
set forth in Section 3.2 or Section 3.3 are not satisfied on or prior to the Closing Date and, as a result thereof,
the transactions contemplated by this Subscription Agreement are not consummated at the Closing or (v) November 12, 2021 if the
Closing has not occurred on or prior to such date; provided, that nothing herein will relieve any party from liability for
any willful breach hereof prior to the time of termination, and each party will be entitled to any remedies at law or in equity
to recover losses, liabilities or damages arising from such breach. The Issuer shall promptly notify Subscriber of the termination
of the Merger Agreement promptly after the termination of such agreement. Upon the termination of this Subscription Agreement in
accordance with this Section 6, except as set forth in the proviso to the first sentence of this Section 6, this Subscription Agreement
shall be void and of no further effect and any portion of the Purchase Price paid by the Subscriber to the Issuer in connection
herewith shall promptly (and in any event within one (1) Business Day) following such termination be returned to the Subscriber
without any deduction or set-off.

Subscription Agreement.

understandings, agreements, representations and warranties of Subscriber contained in this Subscription Agreement; provided, however,

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

Information. The Issuer may request from Subscriber such additional information as the Issuer may deem reasonably necessary

representations and warranties, both written and oral, among the parties, with respect to the subject matter hereof.


 


7.9 Modifications
and Amendments. This Subscription Agreement may not be amended, modified or waived except by an instrument in writing, signed
by each of the parties hereto, provided that in each case Section 2, Section 7.2, Section 7.3, this Section 7.9 and Section 7.11

7.11 Benefit.
Except as otherwise provided herein, this Subscription Agreement is intended for the benefit of the parties hereto and their heirs,
executors, administrators, successors, legal representatives, and permitted assigns and is not for the benefit of, nor may any
provision hereof be enforced by, any other person. Except as set forth in Section 4, Section 7.2, Section 7.3 and this Section
7.11 with respect to the persons specifically referenced therein, this Subscription Agreement shall not confer any rights or remedies
upon any person other than the parties hereto, and their respective successors and assigns, and the parties hereto acknowledge
that such persons specifically referenced, including the Company and the Placement Agents, are third-party beneficiaries of this
Subscription Agreement for the purposes of, and to the extent of, the rights granted to them, if any, pursuant to the applicable
provisions.


 


7.12 Governing
Law. This Subscription Agreement, and any claim or cause of action hereunder based upon, arising out of or related to this
Subscription Agreement (whether based on law, in equity, in contract, in tort or any other theory) or the negotiation, execution,
performance or enforcement of this Subscription Agreement, shall be governed by, and construed in accordance with, the laws of
the State of New York, without regard to the principles of conflicts of laws that would otherwise require the application of the
law of any other state.


 


7.13 Waiver
of Jury Trial. EACH PARTY AND ANY PERSON ASSERTING RIGHTS AS A THIRD-PARTY BENEFICIARY HEREBY WAIVES ITS 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 OR THE TRANSACTIONS
CONTEMPLATED HEREBY 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.


 


7.14 Consent
to Jurisdiction. 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 United States District Court for the Southern District of New York, the
Supreme Court of the State of New York and the federal courts of the United States of America located in the State of New York,
and sitting in the County of New York (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 7.7 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.


 






    -25-


     


    

 


7.15 Severability.
If any provision of this Subscription Agreement shall be invalid, illegal or unenforceable, the validity, legality or enforceability
of the remaining provisions of this Subscription Agreement shall not in any way be affected or impaired thereby and shall continue
in full force and effect so long as this Subscription Agreement as so modified continues to express, without material change, the
original intentions of the parties as to the subject matter hereof and the prohibited nature, invalidity or unenforceability of
the provision(s) in question does not substantially impair the respective expectations or reciprocal obligations of the parties
or the practical realization of the benefits that would otherwise be conferred upon the parties. The parties will endeavor in good
faith negotiations to replace the prohibited, invalid or unenforceable provision(s) with a valid provision(s), the effect of which
comes as close as possible to that of the prohibited, invalid or unenforceable provision(s).


 


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


 


7.17 Remedies.


 


7.17.1 The
parties agree that irreparable damage would occur if this Subscription Agreement was not performed or the Closing is not consummated
in accordance with its specific terms or was otherwise breached and that money damages or other legal remedies would not be an
adequate remedy for any such damage. It is accordingly agreed that the parties hereto shall be entitled to equitable relief, including
in the form of an injunction or injunctions, to prevent breaches or threatened breaches of this Subscription Agreement and to enforce
specifically the terms and provisions of this Subscription Agreement in Designated Court as set forth in Section 7.14, this
being in addition to any other remedy to which any party is entitled at law, in equity, in contract, in tort or otherwise, including
money damages.  The right to specific enforcement shall include the right of the Issuer or the Company to cause Subscriber
and the right of the Company or the Subscriber to cause the Issuer to cause the transactions contemplated hereby to be consummated
on the terms and subject to the conditions and limitations set forth in this Subscription Agreement. The parties hereto further
agree (i) to waive any requirement for the security or posting of any bond in connection with any such equitable remedy, (ii) not
to assert that a remedy of specific enforcement pursuant to this Section 7.17 is unenforceable, invalid, contrary to applicable
law or inequitable for any reason and (iii) to waive any defenses in any action for specific performance, including the defense
that a remedy at law would be adequate. 


 






    -26-


     


    

 


7.17.2 The
parties acknowledge and agree that this Section 7.17 is an integral part of the transactions contemplated hereby and without
that right, the parties hereto would not have entered into this Subscription Agreement.


 


7.17.3 In
any dispute arising out of or related to this Subscription Agreement, or any other agreement, document, instrument or certificate
contemplated hereby, or any transactions contemplated hereby or thereby, the applicable adjudicating body shall award to the prevailing
party, if any, the reasonable and documented out-of-pocket costs and attorneys’ fees reasonably incurred by the prevailing
party in connection with the dispute and the enforcement of its rights under this Subscription Agreement or any other agreement,
document, instrument or certificate contemplated hereby and, if the adjudicating body determines a party to be the prevailing party
under circumstances where the prevailing party won on some but not all of the claims and counterclaims, the adjudicating body may
award the prevailing party an appropriate percentage of the costs and attorneys’ fees reasonably incurred by the prevailing
party in connection with the adjudication and the enforcement of its rights under this Subscription Agreement or any other agreement,
document, instrument or certificate contemplated hereby or thereby.


 


7.18 Survival
of Representations and Warranties. All representations and warranties made by the parties hereto in this Subscription Agreement
shall survive the Closing. For the avoidance of doubt, if for any reason the Closing does not occur prior to the consummation of
the Transactions, all representations, warranties, covenants and agreements of the parties hereunder shall survive the consummation
of the Transactions and remain in full force and effect, unless this Subscription Agreement is terminated in accordance with Section
6, in which case, all representations, warranties, covenants and agreements of the parties hereunder shall survive until such termination
of this Subscription Agreement.


 


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


 


7.20 Headings
and Captions. The headings and captions of the various subdivisions of this Subscription Agreement are for convenience of reference
only and shall in no way modify or affect the meaning or construction of any of the terms or provisions hereof.


 






    -27-


     


    

 


7.21 Counterparts.
This Subscription Agreement may be executed in one or more counterparts, all of which when taken together shall be considered one
and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other parties,
it being understood that the parties need not sign the same counterpart. In the event that any signature is delivered by facsimile
transmission or any other form of electronic delivery (including .pdf or any electronic signature complying with the U.S. federal
ESIGN Act of 2000, e.g., www.docusign.com), such signature shall create a valid and binding obligation of the party executing (or
on whose behalf such signature is executed) with the same force and effect as if such signature page were an original thereof.


 


7.22 Construction.
The words “include,” “includes,” and “including” will be deemed to be
followed by “without limitation.” Pronouns in masculine, feminine, and neuter genders will be construed to include
any other gender, and words in the singular form will be construed to include the plural and vice versa, unless the context otherwise
requires. The words “this Subscription Agreement,” “herein,” “hereof,”
“hereby,” “hereunder,” and words of similar import refer to this Subscription Agreement as
a whole and not to any particular subdivision unless expressly so limited. The parties hereto intend that each representation,
warranty, and covenant contained herein will have independent significance. If any party hereto has breached any representation,
warranty, or covenant contained herein in any respect, the fact that there exists another representation, warranty or covenant
relating to the same subject matter (regardless of the relative levels of specificity) which such party hereto has not breached
will not detract from or mitigate the fact that such party hereto is in breach of the first representation, warranty, or covenant.
All references in this Subscription Agreement to numbers of shares, per share amounts and purchase prices shall be appropriately
adjusted to reflect any stock split, stock dividend, stock combination, recapitalization or the like occurring after the date hereof.


 


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


 


7.24 Cleansing
Statement; Consent to Disclosure. The Issuer shall, by 9:00 a.m., New York City time, by the first (1st)
Business Day immediately following the date of this Subscription Agreement (the “Disclosure Time”), issue one
(1) or more press releases or file with the Commission a Current Report on Form 8-K disclosing all material terms of the transactions
contemplated hereby and by the Other Subscription Agreements, the Merger Agreement and the Transactions, including the form of
this Subscription Agreement (collectively, the “Disclosure Document”). From and after the issuance of the Disclosure
Document, Subscriber shall not be in possession of any material, non-public information received from the Issuer or any of its
officers, directors, employees, affiliates or agents, including, without limitation, the Placement Agents, relating to the transactions
contemplated by this Subscription Agreement, and upon the earlier of (i) the Disclosure Time and (ii) the issuance of the Disclosure
Document, the Subscriber shall no longer be subject to any confidentiality or similar obligations under any current agreement,
whether written or oral with Issuer or any of its officers, directors, employees, affiliates or agents, including, without limitation,
the Placement Agents, relating to the transactions contemplated by this Subscription Agreement. The Issuer understands and confirms
that the Subscriber and its affiliates will rely on the foregoing representations in effecting transactions in securities of the
Issuer.


 






    -28-


     


    

 


7.25 Notwithstanding
the foregoing, the Issuer shall not publicly disclose the name of Subscriber or any affiliate or investment adviser of Subscriber,
or include the name of Subscriber or any affiliate or investment adviser of Subscriber in any press release or in any filing with
the Commission or any regulatory agency or trading market, without the prior written consent (including by e-mail) of Subscriber,
except as required by the federal securities laws, rules or regulations and to the extent such disclosure is required by other
laws, rules or regulations, at the request of the staff of the Commission or regulatory agency or under NYSE regulations, in which
case the Issuer shall provide Subscriber with prior written notice (including by e-mail) of such permitted disclosure, and shall
reasonably consult with Subscriber regarding such disclosure. Subscriber will promptly provide any information reasonably requested
by the Issuer for any regulatory application or filing made or approval sought in connection with the Transactions (including filings
with the Commission) to the extent such information is readily available and to the extent consistent with its internal policies
and procedures.


 


8. Trust
Account Waiver. Subscriber hereby acknowledges that, as described in the Issuer’s prospectus relating to its initial
public offering (the “IPO”) dated November 6, 2019 available at www.sec.gov, the Issuer has established a trust
account (the “Trust Account”) containing the proceeds of the IPO (including interest accrued from time to time
thereon) for the benefit of the Issuer, its public stockholders and certain other parties (including the underwriters of the IPO).
For and in consideration of the Issuer entering into this Subscription Agreement, and for other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, Subscriber hereby (a) agrees that it does not now and shall not at
any time hereafter have any right, title, interest or claim of any kind in or to any assets held in the Trust Account, and shall
not make any claim against the Trust Account, arising out or as a result of, in connection with or relating in any way to this
Subscription Agreement, and regardless of whether such claim arises based on contract, tort, equity or any other theory of legal
liability (any and all such claims are collectively referred to hereafter as the “Released Claims”), (b) irrevocably
waives any Released Claims that it may have against the Trust Account now or in the future as a result of, or arising out of, this
Subscription Agreement, and (c) will not seek recourse against the Trust Account as a result of, in connection with or relating
in any way to this Subscription Agreement; provided, however, that nothing in this Section 8 shall be deemed to limit any Subscriber’s
right to distributions from the Trust Account in accordance with the Issuer’s amended and restated certificate of incorporation
in respect of any redemptions by Subscriber in respect of Class A common stock acquired by any means other than pursuant to this
Subscription Agreement.
