REGISTRATIONS

 

2.1 Shelf
Registration.

 

2.1.1 Filing.
The Company shall file, as soon as practicable, but in any event within sixty (60) days after the Closing Date (the “Filing
Deadline”), a Registration Statement for a Shelf Registration on Form S-1 (the “Form S-1 Shelf”)
or, if the Company is eligible to use a Form S-3 Shelf, a Registration Statement for a Shelf Registration on Form S-3 (the “Form
S-3 Shelf”), in each case, covering the resale of all the Registrable Securities (determined as of two business days prior
to such filing) on a delayed or continuous basis. The Company shall use commercially reasonable efforts to cause such Shelf Registration
to be declared effective as soon as possible after filing, but in no event later than the earlier of (i) sixty (60) days following the
Filing Deadline and (ii) three (3) business days after the Commission notifies the Company that it will not review such Shelf Registration,
if applicable (the “Effectiveness Deadline”); provided, that, if such Shelf Registration filed pursuant to
this Section 2.1.1 is reviewed by, and the Company receives comments from, the Commission with respect to such Shelf Registration,
the Effectiveness Deadline shall be extended to ninety (90) days following the Filing Deadline. Such Shelf Registration shall provide
for the resale of the Registrable Securities included therein pursuant to any method or combination of methods legally available to,
and requested by, any Holder named therein (and the FF Beneficial Investor if the FF Investor submits such request). The Company shall
maintain a Shelf Registration in accordance with the terms hereof, and shall prepare and file with the Commission such amendments, including
post-effective amendments, and supplements as may be necessary to keep a Shelf Registration continuously effective, available for use
and in compliance with the provisions of the Securities Act until such time as there are no longer any Registrable Securities. In the
event the Company files a Form S-1 Shelf, the Company shall use its commercially reasonable efforts to convert the Form S-1 Shelf (and
any Subsequent Shelf Registration) to a Form S-3 Shelf as soon as practicable after the Company is eligible to use Form S-3.

 

    5

     

    

 

2.1.2 Subsequent
Shelf Registration. If any Shelf Registration ceases to be effective under the Securities Act for any reason at any time while Registrable
Securities are still outstanding, the Company shall, subject to Section 3.4, use its commercially reasonable efforts to promptly
cause such Shelf Registration to again become effective under the Securities Act (including obtaining the prompt withdrawal of any order
suspending the effectiveness of such Shelf Registration), and shall use its commercially reasonable efforts to promptly amend such Shelf
Registration in a manner reasonably expected to result in the withdrawal of any order suspending the effectiveness of such Shelf Registration
or file an additional registration statement as a Shelf Registration (a “Subsequent Shelf Registration”) registering
the resale of all Registrable Securities (determined as of two business days prior to such filing), and pursuant to any method or combination
of methods legally available to, and requested by, any Holder named therein. If a Subsequent Shelf Registration is filed, the Company
shall use its commercially reasonable efforts to (i) cause such Subsequent Shelf Registration to become effective under the Securities
Act as promptly as is reasonably practicable after the filing thereof (it being agreed that the Subsequent Shelf Registration shall be
an automatic shelf registration statement (as defined in Rule 405 promulgated under the Securities Act) if the Company is a well-known
seasoned issuer (as defined in Rule 405 promulgated under the Securities Act) at the most recent applicable eligibility determination
date) and (ii) keep such Subsequent Shelf Registration continuously effective, available for use and in compliance with the provisions
of the Securities Act until such time as there are no longer any Registrable Securities. Any such Subsequent Shelf Registration shall
be on Form S-3 to the extent that the Company is eligible to use such form. Otherwise, such Subsequent Shelf Registration shall be on
another appropriate form.

 

2.1.3 Requests
for Underwritten Shelf Takedowns. At any time and from time to time when an effective Shelf Registration is on file with the Commission,
and subject to the expiration of the Applicable Lock-Up Period, one or more of the Holders (such Holder or Holders being in such case,
“Demanding Holders”) may request to sell all or any portion of its Registrable Securities in an Underwritten
Offering that is registered pursuant to the Shelf Registration (each, an “Underwritten Shelf Takedown”); provided,
however, that the Company shall only be obligated to effect an Underwritten Shelf Takedown if such offering shall include Registrable
Securities proposed to be sold by the Demanding Holders with a total offering price reasonably expected to exceed, in the aggregate,
$50,000,000 (the “Minimum Takedown Threshold”). All requests for Underwritten Shelf Takedowns shall be made
by giving written notice to the Company, which shall specify the approximate number of Registrable Securities proposed to be sold by
the Demanding Holders in the Underwritten Shelf Takedown. Subject to Section 2.4.4, the Company shall have the right to select
the Underwriters for such offering (which shall consist of one or more reputable nationally recognized investment banks), subject to
the initial Demanding Holders’ prior approval (which shall not be unreasonably withheld, conditioned or delayed). The Holders may
demand not more than two (2) Underwritten Shelf Takedowns in any twelve (12) month period.

 

2.1.4 Reduction
of Underwritten Offering. If the managing Underwriter or Underwriters in an Underwritten Shelf Takedown, in good faith, advises the
Company, the Demanding Holders and the Holders requesting piggy back rights pursuant to this Agreement with respect to such Underwritten
Shelf Takedown (the “Requesting Holders”) (if any) that the dollar amount or number of Registrable Securities
that the Demanding Holders and the Requesting Holders (if any) desire to sell, taken together with all other shares of Common Stock or
other equity securities that the Company desires to sell and all other shares of Common Stock or other equity securities, if any, that
have been requested to be sold in such Underwritten Offering pursuant to separate written contractual piggy-back registration rights
held by any other stockholders, exceeds the maximum dollar amount or maximum number of equity securities that can be sold in the Underwritten
Offering without adversely affecting the proposed offering price, the timing, the distribution method, or the probability of success
of such offering (such maximum dollar amount or maximum number of such securities, as applicable, the “Maximum Number of
Securities”), then the Company shall include in such Underwritten Offering, before including any shares of Common Stock
or other equity securities proposed to be sold by Company or by other holders of Common Stock or other equity securities, the Registrable
Securities of the Demanding Holders and the Requesting Holders (if any) (pro rata based on the respective number of Registrable Securities
that each Demanding Holder and Requesting Holder (if any) has requested be included in such Underwritten Shelf Takedown and the aggregate
number of Registrable Securities that the Demanding Holders and Requesting Holders have requested be included in such Underwritten Shelf
Takedown) that can be sold without exceeding the Maximum Number of Securities.

 

    6

     

    

 

2.1.5 Withdrawal.
Prior to the filing of the applicable “red herring” prospectus or prospectus supplement used for marketing such Underwritten
Shelf Takedown, a majority-in-interest of the Demanding Holders initiating an Underwritten Shelf Takedown shall have the right to withdraw
from such Underwritten Shelf Takedown for any or no reason whatsoever upon written notification (a “Withdrawal Notice”)
to the Company and the Underwriter or Underwriters (if any) of their intention to withdraw from such Shelf Takedown; provided
that the other Initial Investors or the other NextNav Investors may elect to have the Company continue an Underwritten Shelf Takedown
if the Minimum Takedown Threshold would still be satisfied by the Registrable Securities proposed to be sold in the Underwritten Shelf
Takedown by the other Initial Investors or the other NextNav Investors, as applicable. If withdrawn, a demand for an Underwritten Shelf
Takedown shall constitute a demand for an Underwritten Shelf Takedown for purposes of Section 2.1.3, unless the Demanding
Holders reimburse the Company for all Registration Expenses with respect to such Underwritten Shelf Takedown. Following the receipt of
any Withdrawal Notice, the Company shall promptly forward such Withdrawal Notice to any other Holders that had elected to participate
in such Shelf Takedown.

 

2.2 Piggyback
Registration.

 

2.2.1 Piggyback
Rights. Subject to Section 2.4.3, if the Company or any Holder proposes to conduct a registered offering of, or if the
Company proposes to file a Registration Statement under the Securities Act with respect to the Registration of, equity securities, or
securities or other obligations exercisable or exchangeable for, or convertible into equity securities, for its own account or for the
account of stockholders of the Company (or by the Company and by the stockholders of the Company including, without limitation, an Underwritten
Shelf Takedown pursuant to Section 2.1.3 hereof), other than a Registration Statement (or any registered offering with respect
thereto) (i) filed in connection with any employee stock option or other benefit plan, (ii) pursuant to a Registration Statement on Form
S-4 (or similar form that relates to a transaction subject to Rule 145 under the Securities Act or any successor rule thereto), (iii)
for an offering of debt that is convertible into equity securities of the Company or (iv) for a dividend reinvestment plan, then the
Company shall give written notice of such proposed offering to all of the Holders of Registrable Securities and the FF Beneficial Investor
as soon as practicable but not less than ten (10) days before the anticipated filing date of such Registration Statement or, in the case
of an Underwritten Offering pursuant to a Shelf Registration, the applicable “red herring” prospectus or prospectus supplement
used for marketing such offering, which notice shall (A) describe the amount and type of securities to be included in such offering,
the intended method(s) of distribution, and the name of the proposed managing Underwriter or Underwriters, if any, in such offering,
and (B) offer to all of the Holders of Registrable Securities the opportunity to include in such registered offering such number of Registrable
Securities as such Holders may request in writing within five (5) days after receipt of such written notice (such registered offering,
a “Piggyback Registration”). Subject to Section 2.2.2, the Company shall, in good faith, cause
such Registrable Securities to be included in such Piggyback Registration and, if applicable, shall use its commercially reasonable efforts
to cause the managing Underwriter or Underwriters of such Piggyback Registration to permit the Registrable Securities requested by the
Holders pursuant to this Section 2.2.1 to be included therein on the same terms and conditions as any similar securities
of the Company included in such registered offering and to permit the sale or other disposition of such Registrable Securities in accordance
with the intended method(s) of distribution thereof. The inclusion of any Holder’s Registrable Securities in a Piggyback Registration
shall be subject to such Holder agreement to enter into an underwriting agreement in customary form with the Underwriter(s) selected
for such Underwritten Offering. Notwithstanding anything to the contrary in the foregoing, neither the FF Investor nor the FF Beneficial
Investor shall be required to execute any agreement, instrument or other document pursuant to this Section 2.2 unless such agreement,
instrument or other document contains a limitation of liability provision in the form of Section 6.10.

hereof, and (iii) the shares of Common Stock or other equity securities, if any, as to which Registration or a registered offering has

the Maximum Number of Securities, then:

 

(a) If
the Registration or registered offering is undertaken for the Company’s account, the Company shall include in any such Registration
or registered offering: (A) first, the shares of Common Stock or other equity securities that the Company desires to sell, which can

the foregoing clause (A), the Registrable Securities of Holders exercising their rights to register their Registrable Securities pursuant

(60)-day period (or such shorter time agreed to by the managing Underwriter(s)) beginning on the date of pricing of such offering, except
in the event the Underwriters managing the offering otherwise agree by written consent. Each Holder of Registrable Securities agrees
to execute a customary lock-up agreement in favor of the Underwriters to such effect (in each case on substantially the same terms and
conditions as all such Holders). For the sake of clarity, no Holder shall be obligated under the provisions of this Section 2.3
to the extent such Holder no longer owns Registrable Securities.

 

2.4 Block
Trades.

 

2.4.1 Notwithstanding
the foregoing, at any time and from time to time when an effective Shelf Registration is on file with the Commission, if a Demanding
Holder wishes to engage in an underwritten registered offering not involving a “roadshow,” an offer commonly known as a “block
trade” (a “Block Trade”), with a total offering price reasonably expected to exceed, in the aggregate,
either (x) $50 million or (y) all remaining Registrable Securities held by the Demanding Holder, then notwithstanding the time periods
provided for in Section 2.1.3, such Demanding Holder only need to notify the Company of the Block Trade at least five (5)
business days prior to the day such offering is to commence and the Company shall as expeditiously as possible use its commercially reasonable
efforts to facilitate such Block Trade; provided that the Demanding Holders representing a majority of the Registrable Securities
wishing to engage in the Block Trade shall use commercially reasonable efforts to work with the Company and any Underwriters prior to
making such request in order to facilitate preparation of the registration statement, prospectus and other offering documentation related
to the Block Trade.

 

2.4.2 Prior
to the filing of the applicable “red herring” prospectus or prospectus supplement used in connection with a Block Trade,
a majority-in-interest of the Demanding Holders initiating such Block Trade shall have the right to submit a Withdrawal Notice to the
Company and the Underwriter or Underwriters (if any) of their intention to withdraw from such Block Trade. Notwithstanding anything to
the contrary in this Agreement, the Company shall be responsible for the Registration Expenses incurred in connection with a block trade
prior to its withdrawal under this Section 2.4.2.

 

2.4.3 Notwithstanding
anything to the contrary in this Agreement, Section 2.2 hereof shall not apply to a Block Trade initiated by a Demanding
Holder pursuant to this Agreement.

 

2.4.4 The
Demanding Holder in a Block Trade shall have the right to select the Underwriters for such Block Trade (which shall consist of one or
more reputable nationally recognized investment banks).

 

2.5 Original
Registration Agreement. The Initial Investors acknowledge and agree that this Agreement shall supersede the Original Registration
Agreement, which shall be of no further force or effect.

COMPANY PROCEDURES

 

3.1 General
Procedures. If the Company is required to effect the Registration of Registrable Securities, the Company shall use its commercially
reasonable efforts to effect such Registration to permit the sale of such Registrable Securities in accordance with the intended plan
of distribution thereof, and pursuant thereto the Company shall, as expeditiously as possible:

 

3.1.1 prepare
and file with the Commission as soon as practicable a Registration Statement with respect to such Registrable Securities and use its
commercially reasonable efforts to cause such Registration Statement to become effective and remain effective until all Registrable Securities
covered by such Registration Statement have been sold;

 

3.1.2 prepare
and file with the Commission such amendments and post-effective amendments to the Registration Statement, and such supplements to the
Prospectus, as may be requested by any Holder or any Underwriter of Registrable Securities or as may be required by the rules, regulations
or instructions applicable to the registration form used by the Company or by the Securities Act or rules and regulations thereunder
to keep the Registration Statement effective until all Registrable Securities covered by such Registration Statement are sold in accordance
with the intended plan of distribution set forth in such Registration Statement or supplement to the Prospectus;

 

3.1.3 prior
to filing a Registration Statement or Prospectus, or any amendment or supplement thereto, furnish without charge to the Underwriters,
if any, and each Holder of Registrable Securities included in such Registration, the FF Beneficial Investor (provided that the FF Investor
remains a Holder holding such Registrable Securities) and each such Holder’s legal counsel, copies of such Registration Statement
as proposed to be filed, each amendment and supplement to such Registration Statement (in each case including all exhibits thereto and
documents incorporated by reference therein), the Prospectus included in such Registration Statement (including each preliminary Prospectus),
and such other documents as the Underwriters and each Holder of Registrable Securities included in such Registration or the FF Beneficial
Investor or the legal counsel for any such Holders may request in order to facilitate the disposition of the Registrable Securities owned
by such Holders;

 

3.1.4 prior
to any public offering of Registrable Securities, use its commercially reasonable efforts to (i) register or qualify the Registrable
Securities covered by the Registration Statement under such securities or “blue sky” laws of such jurisdictions in the United
States as any Holder of Registrable Securities included in such Registration Statement (in light of their intended plan of distribution)
may request and (ii) take such action necessary to cause such Registrable Securities covered by the Registration Statement to be registered
with or approved by such other governmental authorities as may be necessary by virtue of the business and operations of the Company and
do any and all other acts and things that may be necessary or advisable to enable the Holders of Registrable Securities included in such
Registration Statement to consummate the disposition of such Registrable Securities in such jurisdictions; provided, however,
that the Company shall not be required to qualify generally to do business in any jurisdiction where it would not otherwise be required
to qualify or take any action to which it would be subject to general service of process or taxation in any such jurisdiction where it
is not then otherwise so subject;

 

3.1.5 cause
all such Registrable Securities to be listed on each securities exchange or automated quotation system on which similar securities issued
by the Company are then listed;

 

3.1.6 provide
a transfer agent or warrant agent, as applicable, and registrar for all such Registrable Securities no later than the effective date
of such Registration Statement;

 

3.1.7 advise
each seller of such Registrable Securities, promptly after it shall receive notice or obtain knowledge thereof, of the issuance of any
stop order by the Commission suspending the effectiveness of such Registration Statement or the initiation or threatening of any proceeding
for such purpose and promptly use its commercially reasonable efforts to prevent the issuance of any stop order or to obtain its withdrawal
if such stop order should be issued;

 

3.1.8 at
least five (5) days prior to the filing of any Registration Statement or Prospectus or any amendment or supplement to such Registration
Statement or Prospectus or any document that is to be incorporated by reference into such Registration Statement or Prospectus, furnish
a copy thereof to each seller of such Registrable Securities and its counsel, including, without limitation, providing copies promptly
upon receipt of any comment letters received with respect to any such Registration Statement or Prospectus;

 

    10

     

    

 

3.1.9 notify
the Holders and the FF Beneficial Investor at any time when a Prospectus relating to such Registration Statement is required to be delivered
under the Securities Act, of the happening of any event as a result of which the Prospectus included in such Registration Statement,
as then in effect, includes a Misstatement, and then to correct such Misstatement as set forth in Section 3.4 hereof;

 

3.1.10 permit
a representative of the Holders and the FF Beneficial Investor, the Underwriters, if any, and any attorney or accountant retained by
such Holders, the FF Beneficial Investor or Underwriter to participate, at each such person’s own expense, in the preparation of
the Registration Statement, and cause the Company’s officers, directors and employees to supply all information reasonably requested
by any such representative, Underwriter, attorney or accountant in connection with the Registration; provided, however,
that such representatives or Underwriters agree to confidentiality arrangements reasonably satisfactory to the Company, prior to the
release or disclosure of any such information;

 

3.1.11 obtain
a “cold comfort” letter from the Company’s independent registered public accountants in the event of an Underwritten
Registration which the participating Holders and the FF Beneficial Investor may rely on, in customary form and covering such matters
of the type customarily covered by “cold comfort” letters as the managing Underwriter may reasonably request, and reasonably
satisfactory to a majority-in-interest of the participating Holders;

 

3.1.12 on
the date the Registrable Securities are delivered for sale pursuant to such Registration, obtain an opinion, dated such date, of counsel
representing the Company for the purposes of such Registration, addressed to the Holders and the FF Beneficial Investor, the placement
agent or sales agent, if any, and the Underwriters, if any, covering such legal matters with respect to the Registration in respect of
which such opinion is being given as the Holders, the FF Beneficial Investor, placement agent, sales agent, or Underwriter may reasonably
request and as are customarily included in such opinions and negative assurance letters, and reasonably satisfactory to a majority in
interest of the participating Holders;

 

3.1.13 in
the event of any Underwritten Offering, enter into and perform its obligations under an underwriting agreement, in usual and customary
form, with the managing Underwriter of such offering;

 

3.1.14 make
available to its security holders, as soon as reasonably practicable, an earnings statement covering the period of at least twelve (12)
months beginning with the first day of the Company’s first full calendar quarter after the effective date of the Registration Statement
which satisfies the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder (or any successor rule promulgated
thereafter by the Commission);

 

3.1.15 with
respect to an Underwritten Offering pursuant to Section 2.1.4, use its commercially reasonable efforts to make available senior
executives of the Company to participate in customary “road show” presentations that may be reasonably requested by the Underwriter
in such Underwritten Offering; and

 

3.1.16 otherwise,
in good faith, cooperate reasonably with, and take such customary actions as may reasonably be requested by the Holders or the FF Beneficial
Investor, in connection with such Registration.

 

Notwithstanding
the foregoing, the Company shall not be required to provide any documents or information to an Underwriter if such Underwriter has not
then been named with respect to the applicable Underwritten Offering.

 

3.2 Registration
Expenses. The Registration Expenses of all Registrations shall be borne by the Company. It is acknowledged by the Holders that the
Holders shall bear all incremental selling expenses relating to the sale of Registrable Securities, such as Underwriters’ commissions
and discounts, brokerage fees, Underwriter marketing costs and, other than as set forth in the definition of “Registration Expenses,”
all reasonable fees and expenses of any legal counsel representing the Holders.

 

    11

     

    

 

3.3 Requirements
for Participation in Underwritten Offerings. Notwithstanding anything in this Agreement to the contrary, if any Holder does not provide
the Company with its requested Holder Information, the Company may exclude such Holder’s Registrable Securities from the applicable
Registration Statement or Prospectus if the Company determines, based on the advice of counsel, that such information is necessary to
effect the registration and such Holder continues thereafter to withhold such information. No person may participate in any Underwritten
Offering for equity securities of the Company pursuant to a Registration initiated by the Company hereunder unless such person (i) agrees
to sell such person’s securities on the basis provided in any underwriting arrangements approved by the Company and (ii) completes
and executes all customary questionnaires, powers of attorney, indemnities, lock-up agreements, underwriting agreements and other customary
documents as may be reasonably required under the terms of such underwriting arrangements. The exclusion of a Holder’s Registrable
Securities as a result of this Section 3.3 shall not affect the registration of the other Registrable Securities to be included
in such Registration.

 

3.4 Suspension
of Sales; Adverse Disclosure.

 

3.4.1 Upon
receipt of written notice from the Company that a Registration Statement or Prospectus contains a Misstatement, each of the Holders shall
forthwith discontinue disposition of Registrable Securities until it has received copies of a supplemented or amended Prospectus correcting
the Misstatement (it being understood that the Company hereby covenants to prepare and file such supplement or amendment as soon as practicable
after the time of such notice), or until it is advised in writing by the Company that the use of the Prospectus may be resumed.

 

3.4.2 Subject
to Section 3.4.4, if the filing, initial effectiveness or continued use of a Registration Statement in respect of any Registration
at any time would (a) require the Company to make an Adverse Disclosure, (b) require the inclusion in such Registration Statement of
financial statements that are unavailable to the Company for reasons beyond the Company’s control, or (c) in the good faith judgment
of the majority of the Board, be detrimental to the Company and the majority of the Board concludes as a result that it is advisable
to defer such filing, initial effectiveness or continued use at such time, the Company may, upon giving prompt written notice of such
action to the Holders and the FF Beneficial Investor, delay the filing or initial effectiveness of, or suspend use of, such Registration
Statement for the shortest period of time determined in good faith by the Company to be necessary for such purpose. In the event the
Company exercises its rights under this Section 3.4.2, the Holders agree to suspend, immediately upon their receipt of the notice
referred to above, their use of the Prospectus relating to any Registration in connection with any sale or offer to sell Registrable
Securities.

 

3.4.3 Subject
to Section 3.4.4, (a) during the period starting with the date sixty (60) days prior to the Company’s good faith estimate
of the date of the filing of, and ending on a date one hundred and twenty (120) days after the effective date of, a Company-initiated
Registration and provided that the Company continues to actively employ, in good faith, all commercially reasonable efforts to maintain
the effectiveness of the applicable Registration Statement, or (b) if, pursuant to Section 2.1.4, Holders (or the FF Beneficial
Investor) have requested an Underwritten Shelf Takedown and the Company and Holders are unable to obtain the commitment of underwriters
to firmly underwrite such offering, the Company may, upon giving prompt written notice of such action to the Holders (or the FF Beneficial
Investor, if applicable), delay any other registered offering pursuant to Sections 2.1.4 or 2.4.

 

3.4.4 The
right to delay or suspend any filing, initial effectiveness or continued use of a Registration Statement pursuant to Section 3.4.2
or a registered offering pursuant to Section 3.4.3 shall be exercised by the Company, in the aggregate, not more than three
(3) times in any twelve-month period, and any such delay or suspension shall last for no more than sixty (60) days.

 

3.4.5 The
Company shall as promptly as commercially practicable notify the Holders and the FF Beneficial Investor of the expiration of any period
during which it exercised its rights under this Section 3.4.

 

    12

     

    

 

3.5 Reporting
Obligations. As long as any Holder shall own Registrable Securities (or in the case of the FF Investor, as long as it is the holder
of Registrable Securities), the Company, at all times while it shall be a reporting company under the Exchange Act, covenants to file
timely (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the
Company after the date hereof pursuant to Sections 13(a) or 15(d) of the Exchange Act and to promptly furnish the
Holders and the FF Beneficial Investor with true and complete copies of all such filings. The Company further covenants that it shall
take such further action as any Holder may reasonably request, all to the extent required from time to time to enable such Holder to
sell shares of the Common Stock held by such Holder without registration under the Securities Act within the limitation of the exemptions
provided by Rule 144 (or any successor rule promulgated thereafter by the Commission), including providing any legal opinions. Upon the
request of any Holder, the Company shall deliver to such Holder (and to the FF Beneficial Investor in the case that the FF Investor has
made such request) a written certification of a duly authorized officer as to whether it has complied with such requirements.

INDEMNIFICATION AND CONTRIBUTION

 

4.1 Indemnification.

 

4.1.1 The
Company agrees to indemnify, to the extent permitted by law, each Holder of Registrable Securities (which for the purposes of this Section
4.1 shall include the FF Beneficial Investor for so long as the FF Investor is a holder of Registrable Securities), its officers,
members, managers, and directors (if applicable) and each person who controls such Holder (within the meaning of the Securities Act)
against all losses, claims, damages, liabilities and expenses (including attorneys’ fees) resulting from any untrue or alleged
untrue statement of material fact contained in any Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof
or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements
therein not misleading, except insofar as the same are caused by or contained in any information furnished in writing to the Company
by such Holder expressly for use therein. The Company shall indemnify the Underwriters, their officers and directors and each person
who controls such Underwriters (within the meaning of the Securities Act) to the same extent as provided in the foregoing with respect
to the indemnification of the Holder.

 

4.1.2 In
connection with any Registration Statement in which a Holder of Registrable Securities is participating, such Holder shall furnish to
the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such Registration
Statement or Prospectus (the “Holder Information”) and, to the
extent permitted by law, shall indemnify the Company, its directors and officers and agents and each person who controls the Company
(within the meaning of the Securities Act) against any losses, claims, damages, liabilities and expenses (including without limitation
reasonable attorneys’ fees) resulting from any untrue statement of material fact contained in the Registration Statement, Prospectus
or preliminary Prospectus or any amendment thereof or supplement thereto or any omission of a material fact required to be stated therein
or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission is contained
in any information or affidavit so furnished in writing by such Holder expressly for use therein; provided, however,
that the obligation to indemnify shall be several, not joint and several, among such Holders of Registrable Securities, and the liability
of each such Holder of Registrable Securities shall be in proportion to and limited to the net proceeds received by such Holder from
the sale of Registrable Securities pursuant to such Registration Statement. The Holders of Registrable Securities shall indemnify the
Underwriters, their officers, directors and each person who controls such Underwriters (within the meaning of the Securities Act) to
the same extent as provided in the foregoing with respect to indemnification of the Company.

 

4.1.3 Any
person 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 right to indemnification
hereunder to the extent such failure has not materially 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). 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 (plus local 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) or which settlement 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.

 

    13

     

    

 

4.1.4 The
indemnification provided for under this 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 of such indemnified party and shall survive the transfer
of securities. The Company and each Holder of Registrable Securities participating in an offering also agrees to make such provisions
as are reasonably requested by any indemnified party for contribution to such party in the event the Company’s or such Holder’s
indemnification is unavailable for any reason.

 

4.1.5 If
the indemnification provided under Section 4.1 hereof from the indemnifying party is unavailable or insufficient
to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities and expenses 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, claims, damages, liabilities and expenses 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. 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 relates to information supplied by, 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; provided, however,
that the liability of any Holder under this Section 4.1.5 shall be limited to the amount of the net proceeds received
by such Holder in such offering giving rise to such liability. The amount paid or payable by a party as a result of the losses or other
liabilities referred to above shall be deemed to include, subject to the limitations set forth in Sections 4.1.1, 4.1.2 and 4.1.3 above,
any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding. The
parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 4.1.5 were
determined by pro rata allocation or by any other method of allocation, which does not take account of the equitable considerations referred
to in this Section 4.1.5. 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 4.1.5 from any person who was not
guilty of such fraudulent misrepresentation.

5.1 Lock-up.

Investors if, for at least 20 trading days within any 30-trading day period commencing at least 60 days after the Closing Date, the last
sale price of the Common Stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations
and the like); and

 

(c) With
respect to the Private Placement Warrants and Warrant Shares, 30 days after the Closing Date.

 

    14

     

    

 

5.2 Permitted
Transfers. Notwithstanding the provisions set forth in Section 5.1, any Holder or its Permitted Transferees may Transfer
the Transaction Shares, Private Placement Warrants or Warrant Shares during the Applicable Lock-Up Period: (a) to (i) the Company’s
officers or directors, (ii) any affiliates or family members of the Company’s officers or directors, (iii) any direct or indirect
partners, members or equity holders of the Sponsor or any related investment funds or vehicles controlled or managed by such persons
or their respective affiliates, or (iv) any direct or indirect partners, members or equity holders of any NextNav Investor, any affiliates
of any NextNav Investor or any related investment funds or vehicles controlled or managed by such persons or their respective affiliates;

of an individual, by virtue of laws of descent and distribution upon death of the individual; (d) in the case of an individual, pursuant
to a qualified domestic relations order; (e) by virtue of the laws of the State of Delaware or the Sponsor’s limited liability
company agreement upon dissolution of the Sponsor; (f) in connection with any bona fide mortgage, encumbrance or pledge to a financial
institution in connection with any bona fide loan or debt transaction or enforcement thereunder; (g) to the Company; (h) in connection
with a liquidation, merger, stock exchange, reorganization, tender offer approved by the Board or a duly authorized committee thereof
or other similar transaction which results in all of the Company’s stockholders having the right to exchange their shares Common
Stock for cash, securities or other property subsequent to the Closing Date; or (i) in the case of the FF Investor and the FF Beneficial
Investor, to any FF Permitted Transferee provided, however, that in the case of clauses (a) through (e) these permitted
transferees must enter into a written agreement with the Company agreeing to be bound by the transfer restrictions in this ARTICLE
V.

 

5.3 Non-Transaction
Shares. For the avoidance of doubt, with respect to the Sponsor, only Common Stock issued in exchange for the Founder Shares shall
be considered Transaction Shares, and any other Common Stock held by the Sponsor or any of its affiliates shall not be considered Transaction

Securities at the time in question, compliance with any of the provisions, covenants and conditions set forth in this Agreement may be

notwithstanding the foregoing, any amendment hereto or waiver hereof that adversely affects one Holder, solely in its capacity as a holder
of the shares of capital stock of the Company, in a manner that is materially different from the other Holders (in such capacity) shall
require the consent of the Holder so affected. No course of dealing between any Holder or the Company and any other party hereto or any
failure or delay on the part of a Holder or the Company in exercising any rights or remedies under this Agreement shall operate as a
waiver of any rights or remedies of any Holder or the Company. No single or partial exercise of any rights or remedies under this Agreement
by a party shall operate as a waiver or preclude the exercise of any other rights or remedies hereunder or thereunder by such party.

6.7 Other
Registration Rights. Other than (i) the Third-Party Investor Stockholders who have registration rights pursuant to their respective
Subscription Agreements and (ii) as provided in the Warrant Agreement, dated as of October 15, 2020, between the SPAC and Continental
Stock Transfer & Trust Company, the Company represents and warrants that no person, other than a Holder of Registrable Securities
or the FF Beneficial Investor (for so long as the FF Investor is a Holder of Registrable Securities), has any right to require the Company
to register any securities of the Company for sale or to include such securities of the Company in any Registration filed by the Company
for the sale of securities for its own account or for the account of any other person.

 

6.8 Term.
This Agreement shall terminate with respect to any Holder on the date that such Holder no longer holds any Registrable Securities. The
provisions of Section 3.5 and ARTICLE IV shall survive any termination.

 

6.9 Holder
Information. Each Holder agrees, if requested in writing, to represent to the Company the total number of Registrable Securities
held by such Holder in order for the Company to make determinations hereunder.

 

6.10 The
Northern Trust Company Limitation of Liability. The FF Investor enters into and is liable under (a) this Agreement, (b) any other
document or agreement which the FF Investor may be required to provide under this Agreement and (c) any document or agreement executed
by the Company or any other person as agent or attorney of the FF Investor under this Agreement, only in its capacity as custodian for
the FF Beneficial Investor, and to the extent that it is actually indemnified by the FF Beneficial Investor. To the extent that this
Section 6.10 operates to reduce the amounts for which the FF Investor would otherwise be liable to any person, the FF Beneficial
Investor will pay or procure the payment of such shortfall to such person.

FORM
OF SUBSCRIPTION AGREEMENT

 

This
SUBSCRIPTION AGREEMENT (this “Subscription Agreement”) is entered into on [●], 2021, by and among Spartacus
Acquisition Corporation, a Delaware corporation (the “Issuer”), the subscriber party set forth on the signature page
hereto (“Subscriber”), and Spartacus Acquisition Shelf Corp., a Delaware corporation (“Holdings”).

 

WHEREAS,
the Issuer is concurrently with the execution and delivery hereof entering into an Agreement and Plan of Merger (as amended or modified,
the “Merger Agreement”), by and among Issuer, NextNav Holdings LLC, a Delaware limited liability company (the “Company”),
Holdings, and the other merger parties to be named therein (collectively, the “Transaction Parties”), whereby the
parties intend to effect a business combination whereby each of the Issuer and the Company would become wholly-owned subsidiaries of
Holdings, and the stockholders or the Issuer and the equityholders of the Company would receive shares of Holdings’ common stock,
par value $0.0001 per share (“Holdings Shares”), on the terms and subject to the conditions set forth therein (collectively,
the “Transactions”);

 

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

 

WHEREAS,
in connection with the Transactions, each Acquired Share that is issued and outstanding immediately prior to the Effective Time shall
be converted into, and the holder of such Acquired Share shall be entitled to receive, one Holdings Share for such Acquired Share;

 

WHEREAS,
to finance a portion of the Transactions, certain other “qualified institutional buyers” (as defined in Rule 144A under the
Securities Act of 1933, as amended (the “Securities Act”)) or institutional “accredited investors” (as
such term is defined in Rule 501 under the Securities Act), have (severally and not jointly) entered into separate subscription agreements
with the Issuer (the “Other Subscription Agreements”), pursuant to which such investors have agreed to purchase Class
A Shares on or prior to the Closing Date at the Purchase Price; and

 

WHEREAS,
the aggregate amount of Class A Shares to be sold by Issuer pursuant to this Subscription Agreement and the Other Subscription Agreements
equals 20,500,000 Class A Shares.

 

Capitalized
terms used herein without definition shall have the meanings ascribed thereto in the Merger Agreement.

 

NOW,
THEREFORE, in consideration of the foregoing and the mutual representations, warranties and covenants, and subject to the conditions,
herein contained, and intending to be legally bound hereby, the parties hereto hereby agree as follows:

 

1. Subscription.
Subject to the terms and conditions hereof, Subscriber hereby agrees to subscribe for and purchase, and the Issuer hereby agrees to issue
and sell to Subscriber, upon the payment of the Purchase Price, the Acquired Shares (such subscription and issuance, the “Subscription”).

 

     

     

    

 

2. Closing.

 

a. The
closing of the Subscription contemplated hereby (the “Closing”) is contingent upon the substantially concurrent consummation
of the Transactions and shall occur immediately prior thereto. Not less than five (5) business days prior to the scheduled closing date
of the Transactions (the “Closing Date”), the Issuer shall provide written notice to Subscriber (the “Closing
Notice”) of such Closing Date. Subscriber shall deliver to the Issuer no later than one (1) Business Day before the Closing
Date (as specified in the Closing Notice or otherwise agreed to by the Issuer and Subscriber) the Purchase Price for the Acquired Shares
by wire transfer of U.S. dollars in immediately available funds (i) to the account specified by the Issuer in the Closing Notice, to
be held in escrow by the Issuer. On the Closing Date, the Issuer shall deliver to Subscriber (i) the Acquired Shares in book entry (or
if requested by Subscriber in writing at a reasonable time in advance of the Closing, certificated) form, free and clear of any liens
or other restrictions whatsoever (other than those set forth in this Subscription Agreement, arising under any written agreement of which
Subscriber is a party or arising under state or federal securities laws), in the name of Subscriber (or its nominee in accordance with
its delivery instructions) or to a custodian designated by Subscriber, as applicable, and (ii) a copy of the records of the Issuer’s
transfer agent (the “Transfer Agent”) showing Subscriber as the owner of the Acquired Shares on and as of the Closing
Date (the “Subscriber’s Deliveries”). In the event the closing of the Transactions does not occur within five
(5) business days of the Closing Date specified in the Closing Notice, unless otherwise instructed by the Issuer and Subscriber, the
Issuer shall promptly (but not later than two (2) business days thereafter) return the Purchase Price to Subscriber by wire transfer
of U.S. dollars in immediately available funds to the account specified by Subscriber, and any book entries or share certificates shall
be deemed cancelled and any share certificates shall be promptly (but not later than one (1) business day thereafter) returned to the
Issuer. Notwithstanding such return, (i) a failure to close on the expected Closing Date shall not, by itself, be deemed to be a failure
of any of the conditions to Closing set forth in this Section 2 to be satisfied or waived on or prior to the Closing Date, and
(ii) Subscriber shall remain obligated (A) to redeliver funds to the Issuer 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 2.

 

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

 

(i) solely
with respect to Subscriber, the representations and warranties made by the Issuer and Holdings (other than the representations and warranties
set forth in Section 3(b), Section 3(c), Section 3(h), Section 4(b) and Section 4(c)) in this Subscription
Agreement shall be true and correct in all material respects as of the Closing Date (other than those representations and warranties
expressly made as of an earlier date, which shall be true and correct in all material respects as of such date, and other than those
representations and warranties that are qualified as to materiality, Material Adverse Effect or Holdings Material Adverse Effect, which
shall be true and correct in all respects as of the Closing Date), and the representations and warranties made by the Issuer and Holdings
set forth in Section 3(b), Section 3(c), Section 3(h), Section 4(b) and Section 4(c) shall be true
and correct in all respects as of the Closing Date (other than those representations and warranties expressly made as of an earlier date,
which shall be true and correct in all respects as of such date), in each case without giving effect to the consummation of the Transactions;

 

(ii) solely
with respect to the Issuer, the representations and warranties made by Subscriber in this Subscription Agreement shall be true and correct
in all material respects as of the Closing Date (other than those representations and warranties expressly made as of an earlier date,
which shall be true and correct in all material respects as of such date, and other than those representations and warranties that are
qualified as to materiality or Material Adverse Effect, which shall be true and correct in all respects as of the Closing Date), in each
case without giving effect to the consummation of the Transactions;

 

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

 

(iv) no
governmental authority having jurisdiction shall have enacted, issued, promulgated, enforced or entered any material judgment, order,
law, rule or regulation (whether temporary, preliminary or permanent) which is then in effect and has the effect of restraining, enjoining
or otherwise prohibiting or making illegal the consummation of the transactions contemplated by this Subscription Agreement;

 

(v) the
Acquired Shares shall have been approved for listing on the Nasdaq Capital Market (“Nasdaq”), subject to official
notice of issuance;

 

(vi) solely
with respect to Subscriber, no amendment or modification of the Merger Agreement shall have occurred that would reasonably be expected
to materially and adversely affect the economic benefits that Subscriber would reasonably be expected to receive under this Subscription
Agreement;

 

    2

     

    

 

(vii) all
conditions precedent to the closing of the Transactions set forth in the Merger Agreement shall have been satisfied or waived by the
party entitled to the benefit thereof under the Merger Agreement (other than those conditions that may only be satisfied at the closing
of the Transactions, but subject to satisfaction or waiver by such party of such conditions as of the closing of the Transactions); and

 

(viii) solely
with respect to Subscriber, substantially concurrently with the closing of the Transactions, an aggregate of at least $250,000,000 shall
be received, or receivable, by the Issuer pursuant to (i) the closing of the sale of the Class A Shares pursuant to this Subscription
Agreement and the Other Subscription Agreements, plus (ii) the distribution of proceeds to the Company from the Trust Account (as defined
below), after the payments in respect of redemptions, plus (iii) any other form of equity financing entered into on or prior to the Closing
which is on materially the same terms as this Subscription Agreement and the Other Subscription Agreements.

 

c. At
the Closing, the parties hereto shall execute and deliver such additional documents and take such additional actions as the parties reasonably
may deem necessary in order to consummate the Subscription as contemplated by this Subscription Agreement and Holdings shall assume the
Issuer’s obligations hereunder.

 

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

 

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

 

b. The
Acquired Shares have been duly authorized and, when issued and delivered to Subscriber against full payment for the Acquired Shares in
accordance with the terms of this Subscription Agreement and registered with the Transfer Agent, the Acquired Shares will be validly
issued, fully paid and non-assessable and will not have been issued in violation of or subject to any preemptive or similar rights created
under the Issuer’s certificate of incorporation and bylaws or under the laws of the State of Delaware.

 

c. This
Subscription Agreement, the Merger Agreement and the Other Subscription Agreements (collectively, the “Transaction Documents”)
have been duly authorized, executed and delivered by the Issuer and, assuming that the Transaction Documents constitute the valid and
binding agreement of the other parties thereto, are valid and binding obligations of the Issuer, and are enforceable against it in accordance
with their terms, except as may be limited or otherwise affected by (i) bankruptcy, insolvency, reorganization, fraudulent conveyance,
moratorium or other laws relating to or affecting the rights of creditors generally, and (ii) principles of equity, whether considered
at law or equity.

 

d. The
execution, delivery and performance of this Subscription Agreement and the other Transaction Documents, including the issuance and sale
of the Acquired Shares and the consummation of the other transactions contemplated hereby and thereby, will not conflict with or result
in a breach or violation of any of the terms or provisions of, or constitute a default under, or result in the creation or imposition
of any lien, charge or encumbrance upon any of the property or assets of the Issuer pursuant to the terms of: (i) any indenture, mortgage,
deed of trust, loan agreement, lease, license or other agreement or instrument to which the Issuer is a party or by which the Issuer
is bound or to which any of the property or assets of the Issuer is subject; (ii) the organizational documents of the Issuer; or (iii)
any statute or any judgment, order, rule or regulation of any court or governmental agency, taxing authority or regulatory body, domestic
or foreign, having jurisdiction over the Issuer or any of its properties that, in the case of clauses (i) and (iii), would reasonably
be expected to have a material adverse effect on the business, properties, assets, liabilities, operations, condition (including financial
condition), stockholders’ equity or results of operations of the Issuer or materially and adversely affect the validity of the
Acquired Shares or the legal authority or ability of the Issuer to perform in any material respects its obligations hereunder (a “Material
Adverse Effect”).

 

    3

     

    

 

e. There
are no securities or instruments issued by or to which the Issuer is a party containing anti-dilution or similar provisions that will
be triggered by the issuance of (i) the Acquired Shares or (ii) the shares to be issued pursuant to any Other Subscription Agreement,
that have not been or will not be validly waived on or prior to the Closing Date, including such provisions in the Issuer’s Class
B common stock, par value $0.0001 per share (the “Class B Shares”), pursuant to the terms of the Issuer’s certificate
of incorporation.

 

f. The
Issuer is not in default or violation (and no event has occurred which, with notice or the lapse of time or both, would constitute a
default or violation) of any term, condition or provision of (i) the organizational documents of the Issuer, (ii) any loan or credit
agreement, guarantee, note, bond, mortgage, indenture, lease or other agreement, permit, franchise or license to which, as of the date
of this Subscription Agreement, the Issuer is a party or by which the Issuer’s properties or assets are bound or (iii) any statute
or any judgment, order, rule or regulation of any court or governmental agency, taxing authority or regulatory body, domestic or foreign,
having jurisdiction over the Issuer or any of its properties, except, in the case of clauses (ii) and (iii), for defaults or violations
that have not had and would not be reasonably likely to have, individually or in the aggregate, a Material Adverse Effect.

 

g. The
Issuer is not required to obtain any consent, waiver, authorization or order of, give any notice to, or make any filing or registration
with, any court or other federal, state, local or other governmental authority, self-regulatory organization or other person in connection
with the execution, delivery and performance by the Issuer of this Subscription Agreement (including, without limitation, the issuance
of the Acquired Shares), other than: (i) the filing with the Securities and Exchange Commission (the “Commission”)
of the Registration Statement (as defined below); (ii) filings required by applicable state securities laws; (iii) the filing of a Notice
of Exempt Offering of Securities on Form D with the Commission under Regulation D of the Securities Act; (iv) the filings required in
accordance with Section 10(r) of this Subscription Agreement; (v) those required by Nasdaq, including with respect to obtaining
approval of the Issuer’s stockholders; and (vi) any filing, the failure of which to obtain would not be reasonably likely to have,
individually or in the aggregate, a Material Adverse Effect.

 

h. As
of the date of this Subscription Agreement and as of immediately prior to the Closing Date, the authorized capital stock of the Issuer
consists of (i) 1,000,000 shares of preferred stock, par value $0.0001 per share (“Preferred Stock”) and (ii) 220,000,000
shares of common stock, par value $0.0001 per share (the “Common Stock”), including (1) 200,000,000 Class A Shares
and (2) 20,000,000 Class B Shares. As of the date of this Subscription Agreement, (i) no shares of Preferred Stock are issued and outstanding,
(ii) 20,000,000 Class A Shares are issued and outstanding, (iii) 5,000,000 Class B Shares are issued and outstanding and (iv) 10,000,000
redeemable warrants to purchase Class A Shares and 8,750,000 private placement warrants to purchase Class A Shares are outstanding. All
(i) issued and outstanding Class A Shares and Class B Shares have been duly authorized and validly 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 pursuant to the Other Subscription Agreements and the Merger Agreement,
there are no outstanding options, warrants or other rights to subscribe for, purchase or acquire from the Issuer any shares of Common
Stock or other equity interests in the Issuer, or securities convertible into or exchangeable or exercisable for such equity interests.
As of the date hereof, the Issuer 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 Issuer is a party or by which it is bound relating to the voting of any securities of the Issuer, other
than (A) as set forth in the SEC Documents and (B) as contemplated by the Merger Agreement. Except as disclosed in the SEC Documents,
as of March 31, 2021, the Issuer has no outstanding indebtedness.

 

i. The
Issuer has not received any written communication from a governmental entity that alleges that the Issuer is not in compliance with or
is in default or violation of any applicable law, except where such non-compliance, default or violation would not, individually or in
the aggregate, be reasonably likely to have a Material Adverse Effect.

 

j. The
issued and outstanding Class A Shares are registered pursuant to Section 12(b) of the Securities Exchange Act of 1934, as amended (the
“Exchange Act”), and are listed for trading on Nasdaq under the symbol “TMTS.” There is no suit, action,
proceeding or investigation pending or, to the knowledge of the Issuer, threatened against the Issuer by Nasdaq or the Commission with
respect to any intention by such entity to deregister the Class A Shares or prohibit or terminate the listing of the Class A Shares on
Nasdaq, excluding, for the purposes of clarity, the customary ongoing review by Nasdaq of the Issuer’s continued listing application
in connection with the Transactions. The Issuer has taken no action that is designed to terminate the registration of the Class A Shares
under the Exchange Act or the listing of the Class A Shares on Nasdaq.

 

    4

     

    

  

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

 

l. Neither
the Issuer nor any person acting on its behalf has engaged or will engage in any form of general solicitation or general advertising
(within the meaning of Regulation D of the Securities Act) in connection with any offer or sale of the Acquired Shares.

 

m. The
Issuer has not entered into any Other Subscription Agreement (or side letter or similar agreement in respect thereof) on terms (economic
or otherwise) more favorable to such subscriber or investor than as set forth in this Subscription Agreement, nor will any Other Subscription
Agreement be entered into or amended after the date hereof to provide for terms with respect to
the purchase of the Class A Shares that are more favorable to any other subscriber thereunder than the terms of this Subscription
Agreement, unless such amended terms are also offered to the Subscriber.

 

n. The
Issuer’s public reports filed with the Commission, and all subsequent reports (collectively, the “Exchange Act Reports”)
that have been filed with the Commission or sent to stockholders, pursuant to Section 13 of the Exchange Act, did not when filed, and
taken as a whole and as amended to the date hereof, do not contain any untrue statement of a material fact or omit to state a material
fact necessary in order to make the statements made therein, in the light of the circumstances under which they were made, not misleading
and such Exchange Act Reports complied in all material respects with the requirements of the Exchange Act and the rules and regulations
of the Commission promulgated thereunder. The Issuer has timely filed each report, statement, schedule, prospectus, and registration
statement that the Issuer was required to file with the Commission since its inception. There are no material outstanding or unresolved
comments in comment letters from the Commission Staff with respect to any of the Issuer’s filings with the Commission (the “SEC
Documents”). In addition, the Issuer has made available to Subscriber (including via the Commission’s EDGAR system) a
copy of the Exchange Act Reports since its initial registration of the Class A Shares with the Commission. Each of the financial statements
(including, in each case, any notes thereto) contained in the SEC Documents was prepared in accordance with U.S. generally accepted accounting
principles applied on a consistent basis throughout the periods indicated (except as may be indicated in the notes thereto or, in the
case of unaudited statements, as permitted by the Commission’s Form 10-Q) and each fairly presents, in all material respects, the
financial position, results of operations and cash flows of the Issuer as at the respective dates thereof and for the respective periods
indicated therein. Notwithstanding anything to the contrary, the Issuer makes no representation or warranty as to (i) the accounting
treatment of the Issuer’s issued and outstanding warrants, (ii) any deficiencies in disclosure (including with respect to accounting
and disclosure controls) arising from the treatment of such warrants as equity rather than liabilities in the Issuer’s financial
statements, or (iii) the impact of such accounting treatment on any of the other representations and warranties contained in this Section
3.

 

o. Except
for such matters as have not had and would not be reasonably likely to have, individually or in the aggregate, a Material Adverse Effect,
there is no (i) investigation, action, suit, claim or other proceeding, in each case by or before any governmental authority pending,
or, to the knowledge of the Issuer, threatened against the Issuer or (ii) judgment, decree, injunction, ruling or order of any governmental
entity outstanding against the Issuer.

 

p. Except
for placement fees payable to the Placement Agents (as defined herein), the Issuer has not paid, and is not obligated to pay, any brokerage,
finder’s or other fee or commission in connection with its issuance and sale of the Acquired Shares, including, for the avoidance
of doubt, any fee or commission payable to any stockholder or affiliate of the Issuer.

 

q. Except
as provided in this Subscription Agreement and the Other Subscription Agreements, none of the Issuer, its subsidiaries or any of their
affiliates, nor any person acting on their behalf has, directly or indirectly, made any offers or sales of any security or solicited
any offers to buy any security, under circumstances that would require registration of the issuance of any of the Acquired Shares under
the Securities Act, whether through integration with prior offerings pursuant to Rule 502(a) of the Securities Act or otherwise.

 

    5

     

    

 

r. Neither
the Issuer nor any of its subsidiaries has taken any steps to seek protection pursuant to any law or statute relating to bankruptcy,
insolvency, reorganization, receivership, liquidation, administration or winding up or failed to pay its debts when due, nor does the
Issuer or any subsidiary have any knowledge or reason to believe that any of their respective creditors intend to initiate involuntary
bankruptcy proceedings or seek to commence an administration.

 

s. Except
for discussions specifically regarding the offer and sale of the Acquired Shares, the Issuer confirms that neither it nor any other person

to this Subscription Agreement; provided that Subscriber and its pledgee shall be required to comply with the provisions of Section
5(e) hereof in order to effect a sale, transfer or assignment of Acquired Shares to such pledgee. The Issuer hereby agrees to execute
and deliver such documentation as a pledgee of the Acquired Shares may reasonably request in connection with a pledge of the Acquired
Shares to such pledgee by Subscriber.

be able to readily resell the Acquired Shares and may be required to bear the financial risk of an investment in the Acquired Shares
for an indefinite period of time. Subscriber understands that it has been advised to consult legal counsel prior to making any offer,
resale, pledge or transfer of any of the Acquired Shares.

 

f. Subscriber

there have been no representations, warranties, covenants and agreements made to Subscriber by the Issuer or any of its officers, directors
or representatives, expressly or by implication, other than those representations, warranties, covenants and agreements included in this
Subscription Agreement.

 

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

 

h. In
making its decision to purchase the Acquired Shares, Subscriber represents that it has relied solely upon independent investigation made
by Subscriber and the representations, warranties, covenants and agreements made by Issuer herein. Subscriber acknowledges and agrees
that Subscriber has received such information as Subscriber deems necessary in order to make an investment decision with respect to the
Acquired Shares, including with respect to the Issuer, the Company and the Transactions. Subscriber represents and agrees that Subscriber
and Subscriber’s professional advisor(s), if any, have had the opportunity to ask such questions, receive such answers and obtain
such information as Subscriber and such Subscriber’s professional advisor(s), if any, have deemed necessary to make an investment
decision with respect to the Acquired Shares. Subscriber acknowledges and agrees that it has not relied on any statements or other information
provided by the Placement Agents or any of the affiliates of the Placement Agents with respect to the Transactions, the Issuer, the Company
or its decision to purchase the Acquired Shares other than the representations, warranties, covenants and agreements made by Issuer herein.
Subscriber further acknowledges that the information provided to Subscriber (other than the information reflected in the representations
and warranties made herein) is preliminary and subject to change, and that any changes to such information, including, without limitation,
any changes based on updated information, shall in no way affect Subscriber’s obligation to purchase the Acquired Shares hereunder.

i. Subscriber
became aware of this offering of the Acquired Shares solely by means of direct contact between Subscriber and the Issuer or by means
of contact from B. Riley Securities, Inc. or PJT Partners LP, acting as placement agents for the Issuer (each a “Placement Agent”),
and the Acquired Shares were offered to Subscriber solely by direct contact between Subscriber and the Issuer or by contact between Subscriber
and the Placement Agent. Subscriber did not become aware of this offering of the Acquired Shares, nor were the Acquired Shares offered

advice as Subscriber has considered necessary to make an informed investment decision.

investment in the Issuer. Subscriber acknowledges specifically that a possibility of total loss exists.

by the United States, (iv) a Designated National as defined in the Cuban Assets Control Regulations, 31 C.F.R. Part 515, or (v) a non-U.S.
shell bank or providing banking services indirectly to a non-U.S. shell bank (collectively, a “Prohibited Investor”).
Subscriber agrees to provide law enforcement agencies, if requested thereby, such records as required by applicable law, provided that
Subscriber is permitted to do so under applicable law. 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 Subscriber maintains policies and procedures reasonably designed to comply with applicable
obligations under the BSA/PATRIOT Act. Subscriber also represents that, to the extent required, it maintains policies and procedures
reasonably designed to ensure compliance with OFAC-administered sanctions programs, including for the screening of its investors against
the OFAC Lists. Subscriber further represents and warrants that, to the extent required, it maintains policies and procedures reasonably

6. Registration
Rights.

 

a. Holdings
agrees that, within fifteen (15) business days after the Closing Date (the “Filing Date”), Holdings will file with
the Commission (at Holdings’ sole cost and expense) a registration statement registering the resale of the Holdings Shares (the
“Registration Statement”), and Holdings 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 90th
calendar day if the Commission notifies Holdings that it will “review” the Registration Statement) following the Filing Date
and (ii) the 10th business day after the date Holdings 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 if the Commission is closed for operations due to a government shutdown, the
Effectiveness Date shall be extended by the same amount of days that the Commission remains closed for operations; provided, further,
that Holdings’ obligations to include the Holdings Shares in the Registration Statement are contingent upon Subscriber furnishing
in writing to Holdings such information regarding Subscriber, the securities of Holdings held by Subscriber and the intended method of
disposition of the Holdings Shares as shall be reasonably requested by Holdings to effect the registration of the Holdings Shares, and
Subscriber shall execute such documents in connection with such registration as Holdings may reasonably request that are customary of
a selling stockholder in similar situations, including providing that Holdings shall be entitled to postpone and suspend the effectiveness
or use of the Registration Statement during any customary blackout or similar period or as permitted hereunder; provided 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 Holdings Shares. Any failure by Holdings to file the Registration Statement
by the Filing Date or to effect such Registration Statement by the Effectiveness Date shall not otherwise relieve Holdings of its obligations
to file or effect the Registration Statement as set forth above in this Section 6. Holdings will provide a draft of the Registration
Statement to the undersigned for review at least two (2) business days in advance of filing the Registration Statement. In no event shall
the undersigned be identified as a statutory underwriter in the Registration Statement unless requested by the Commission. Notwithstanding
the foregoing, if the Commission prevents Holdings 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 of the Securities Act for the resale of the Holdings Shares by the applicable stockholders
or otherwise, such Registration Statement shall register for resale such number of Holdings Shares which is equal to the maximum number
of Holdings Shares as is permitted by the SEC. In such event, the number of Holdings Shares to be registered for each selling stockholder
named in the Registration Statement shall be reduced pro rata among all such selling stockholders. Holdings will use its commercially
reasonable efforts to maintain the continuous effectiveness of the Registration Statement until all such securities cease to be Registrable
Securities (as defined below) or such shorter period upon which each undersigned party with Registrable Securities included in such Registration
Statement have notified Holdings that such Registrable Securities have actually been sold. Holdings will file all reports, and provide
all customary and reasonable cooperation, necessary to enable the undersigned to resell Registrable Securities pursuant to the Registration
Statement or Rule 144 under the Securities Act (“Rule 144”), as applicable, qualify the Registrable Securities for
listing on the applicable stock exchange, update or amend the Registration Statement as necessary to include Registrable Securities and
provide customary notice to holders of Registrable Securities. “Registrable Securities” shall mean, as of any date
of determination, the Holdings Shares and any other equity security of Holdings issued or issuable with respect to the Holdings Shares
by way of share split, dividend, distribution, recapitalization, merger, exchange, replacement or similar event or otherwise. As to any
particular Registrable Securities, once issued, such securities shall cease to be Registrable Securities at the earliest of (A) when
the undersigned ceases to hold any such Registrable Securities, (B) the date all such Registrable Securities held by the undersigned
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, other than the requirement for Holdings to be in compliance with the current public information
required under Rule 144(c), (C) when they shall have ceased to be outstanding and (D) two years from the date of effectiveness of the
Registration Statement.

 

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

 

(i) except
for such times as Holdings 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 Holdings determines to obtain, continuously effective with respect to Subscriber, and to keep the applicable Registration
Statement or any subsequent shelf registration statement free of any material misstatements or omissions, until the earliest of the following:
(i) Subscriber ceases to hold any such Registrable Securities; (ii) the date all such Registrable Securities 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 other than the requirement for Holdings to be in compliance with the current public information required
under Rule 144(c); and (iii) two years from the effective date of the Registration Statement. The period of time during which Holdings
is required hereunder to keep a Registration Statement effective is referred to herein as the “Registration Period”;

 

    11

     

    

 

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

 

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

 

		(2)	of
                                            any request by the Commission for amendments or supplements to any Registration Statement
                                            or the prospectus included therein or for additional information;

 

		(3)	of
                                            the issuance by the Commission of any stop order suspending the effectiveness of any Registration
                                            Statement or the initiation of any proceedings for such purpose;

 

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

 

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

 

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

 

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

 

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

 

 

    12

     

    

 

c. Notwithstanding
anything to the contrary in this Subscription Agreement, Holdings shall be entitled to delay or postpone the effectiveness of the Registration
Statement, and from time to time to require Subscriber not to sell under the Registration Statement or to suspend the effectiveness thereof,
if the negotiation or consummation of a transaction by Holdings or its subsidiaries is pending or an event has occurred, which negotiation,
consummation or event Holdings’ board of directors reasonably believes, upon the advice of legal counsel, would require additional
disclosure by Holdings in the Registration Statement of material information that Holdings 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 Holdings’
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 Holdings 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. Upon receipt of any written notice
from Holdings of the happening of any Suspension Event during the period that the Registration Statement is effective or if as a result
of a Suspension Event the Registration Statement or related prospectus contains any untrue statement of a material fact or omits to state
any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which
they were made (in the case of the prospectus) not misleading, Subscriber agrees that (i) it will immediately discontinue offers and
sales of the Holdings Shares under the Registration Statement (excluding, for the avoidance of doubt, sales conducted pursuant to Rule
144) until Subscriber receives copies of a supplemental or amended prospectus (which Holdings 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 Holdings 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 Holdings unless otherwise required by law or subpoena. If so directed by Holdings, Subscriber
will deliver to Holdings or, in Subscriber’s sole discretion destroy, all copies of the prospectus covering the Holdings Shares
in Subscriber’s possession; provided, however, that this obligation to deliver or destroy all copies of the prospectus
covering the Holdings Shares shall not apply (i) to the extent Subscriber is required to retain a copy of such prospectus (a) in order
to comply with applicable legal, regulatory, self-regulatory or professional requirements or (b) in accordance with a bona fide pre-existing
document retention policy, or (ii) to copies stored electronically on archival servers as a result of automatic data back-up.

 

d. Subscriber
may deliver written notice (an “Opt-Out Notice”) to Holdings requesting that Subscriber not receive notices from Holdings
otherwise required by this Section 6; provided, however, that Subscriber may later revoke any such Opt-Out Notice
in writing. Following receipt of an Opt-Out Notice from Subscriber (unless subsequently revoked), (i) Holdings shall not deliver any
such notices to Subscriber and Subscriber shall no longer be entitled to the rights associated with any such notice, and (ii) each time
prior to Subscriber’s intended use of an effective Registration Statement, Subscriber will notify Holdings 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 6(d)) and the related suspension period remains in effect, Holdings will
so notify Subscriber, within one (1) business day of Subscriber’s notification to Holdings, by delivering to Subscriber a copy
of such previous notice of Suspension Event, and thereafter will provide Subscriber with the related notice of the conclusion of such
Suspension Event immediately upon its availability.

 

e. Indemnification.

 

(i) Holdings
agrees to indemnify and hold harmless, to the extent permitted by law, Subscriber, its directors, officers, employees, agents, each person
who controls Subscriber (within the meaning of the Securities Act or the Exchange Act) and each affiliate of Subscriber (within the meaning
of Rule 405 under the Securities Act) from and against any and all losses, claims, damages, liabilities and expenses (including, without
limitation, reasonable attorneys’ fees and expenses incurred in connection with defending or investigating any such action or claim)
caused by any untrue or alleged untrue statement of material fact contained in any Registration Statement, prospectus included in any
Registration Statement (“Prospectus”) or preliminary Prospectus or any amendment thereof or supplement thereto or
document incorporated by reference therein or any omission or alleged omission of a material fact required to be stated therein or necessary
to make the statements therein not misleading, except insofar as the same are caused by or contained in any information furnished in
writing to Holdings by or on behalf of such Subscriber expressly for use therein.

 

    13

     

    

 

(ii) In
connection with any Registration Statement in which Subscriber is participating, Subscriber shall furnish to Holdings in writing such
information and affidavits as Holdings reasonably requests for use in connection with any such Registration Statement or Prospectus.
Subscriber agrees, severally and not jointly with any other Person that is a party to the Other Subscription Agreements, to indemnify
and hold harmless, to the extent permitted by law, Holdings, its directors and officers and agents and each person who controls Holdings
(within the meaning of the Securities Act) against any losses, claims, damages, liabilities and expenses (including, without limitation,
reasonable attorneys’ fees) resulting from any untrue statement of material fact contained in the Registration Statement, Prospectus
or preliminary Prospectus or any amendment thereof or supplement thereto or any omission of a material fact required to be stated therein
or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission is contained
in any information or affidavit so furnished in writing by such Subscriber expressly for use therein; provided, however,
that in no event shall the liability of each such Subscriber be greater in amount than the dollar amount of the net proceeds received
by such Subscriber from the sale of Holdings Shares pursuant to such Registration Statement giving rise to such indemnification obligation.

 

(iii) Any
person entitled to indemnification herein shall (1) 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 right to indemnification
hereunder to the extent such failure has not prejudiced the indemnifying party) and (2) 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. An indemnifying party who
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 legal counsel to any indemnified
party a conflict of interest exists 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) or which settlement 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.

 

(iv) 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, employee, agent, affiliate or controlling person of such indemnified
party and shall survive the transfer of the Acquired Shares.

 

(v) If
the indemnification provided under this Section 6(e) from the indemnifying party is unavailable or insufficient to hold harmless
an indemnified party in respect of any losses, claims, damages, liabilities and expenses 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, claims, damages, liabilities and expenses 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. 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 relates to information
supplied by, 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 or other liabilities referred to above shall be deemed to include, subject to the limitations set forth in Sections
6(e)(i), (ii) and (iii) above, 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 6(e)(v) from any person who was not guilty of such fraudulent
misrepresentation. Any contribution pursuant to this Section 6(e)(v) by any seller of Acquired Shares shall be limited in
amount to the amount of net proceeds received by such seller from the sale of such Acquired Shares pursuant to the Registration Statement. 

 

7. 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 Merger Agreement is terminated in accordance with its terms, (b) upon the mutual written agreement of each
of the parties hereto and the Company to terminate this Subscription Agreement, (c) if, on the Closing Date of the Transactions, 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, or (d) written notice by either party to the other party to terminate this Subscription Agreement
if the transactions contemplated by this Subscription Agreement are not consummated on or prior to November 19, 2021; 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 in writing of the termination of the Merger Agreement.

 

    14

     

    

  

8. Additional
Agreements and Waivers of Subscriber.

 

a. Trust
Account Waiver. Subscriber acknowledges that the Issuer is a blank check company with the powers and privileges to effect a merger, asset
acquisition, reorganization or similar business combination involving the Issuer and one or more businesses or assets. Subscriber further
acknowledges that, as described in the Issuer’s prospectus relating to its initial public offering dated October 15, 2020 (the
“October 2020 Prospectus”), available at www.sec.gov, substantially all of the Issuer’s assets consist of the
cash proceeds of the Issuer’s initial public offering and private placements of its securities, and substantially all of those
proceeds have been deposited in a trust account (the “Trust Account”) for the benefit of its public stockholders and
the underwriters of its initial public offering. Except with respect to interest earned on the funds held in the Trust Account that may
be released to the Issuer to pay its tax obligations, if any, the cash in the Trust Account may be disbursed only for the purposes set
forth in the October 2020 Prospectus. For and in consideration of the Issuer entering into this Subscription Agreement, the receipt and
sufficiency of which are hereby acknowledged, Subscriber, on behalf of itself and its affiliates and representatives, hereby irrevocably
waives any and all right, title and interest, or any claim of any kind they have or may have in the future as a result of, or arising
out of, this Subscription Agreement, in or to any monies held in the Trust Account, and agrees not to seek recourse or make or bring
any action, suit, claim or other proceeding against the Trust Account as a result of, or arising out of, this Subscription Agreement,
the transactions contemplated hereby or the Acquired Shares, regardless of whether such claim arises based on contract, tort, equity
or any other theory of legal liability; provided, however, that nothing in this Section 8 shall be deemed to limit
any Subscriber’s right, title, interest or claim to the Trust Account by virtue of such Subscriber’s record or beneficial
ownership of securities of the Issuer acquired by any means other than pursuant to this Subscription Agreement, including but not limited
to any redemption right with respect to any such securities of the Company. Subscriber acknowledges and agrees that it shall not have
any redemption rights with respect to the Acquired Shares pursuant to the Issuer’s certificate of incorporation in connection with
the Transactions or any other business combination, any subsequent liquidation of the Trust Account or the Issuer or otherwise. In the
event Subscriber has any claim against the Issuer as a result of, or arising out of, this Subscription Agreement, the transactions contemplated
hereby or the Acquired Shares, it shall pursue such claim solely against the Issuer and its assets outside the Trust Account and not
against the Trust Account or any monies or other assets in the Trust Account. This paragraph shall survive any termination of this Subscription
Agreement.

 

b. No
Hedging. Subscriber hereby agrees that neither it, nor any person or entity acting on its behalf or pursuant to any understanding with
it, shall execute any short sales or engage in other hedging transactions of any kind with respect to the Acquired Shares during the
period from the date of this Subscription Agreement through the Closing. Nothing in this Section 8(b) shall prohibit such persons
from engaging in hedging transactions with respect to other securities of the Issuer, including Class A Shares acquired 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 Acquired Shares, nor shall this Section 8(b) prohibit any other
investment portfolios of Subscriber that have no knowledge of this Subscription Agreement or of Subscriber’s participation in this
transaction (including Subscriber’s controlled affiliates and/or affiliates) from entering into any short sales or engaging in
other hedging transactions.

 

9. Issuer’s
Covenants.

 

a. Except
as contemplated herein, Holdings, its subsidiaries and their respective affiliates shall not, and shall cause any person acting on behalf
of any of the foregoing to not, take any action or steps that would require registration of the issuance of any of the Holdings Shares
under the Securities Act.

 

    15

     

    

 

b. With
a view to making available to Subscriber the benefits of Rule 144 promulgated under the Securities Act or any other similar rule or regulation
of the Commission that may at any time permit Subscriber to sell securities of the Issuer or Holdings, as applicable, to the public without
registration, Holdings agrees, until the third anniversary of the Closing Date, to:

 

(i)
make and keep public information available, as those terms are understood and defined in Rule 144;

 

(ii) file
with the Commission in a timely manner all reports and other documents required of Holdings under the Securities Act and the Exchange
Act so long as Holdings remains subject to such requirements and the filing of such reports and other documents is required for the applicable
provisions of Rule 144; and

 

(iii) furnish
to Subscriber so long as it owns Holdings Shares, promptly upon request, (x) a written statement by Holdings, if true, that it has complied
with the reporting requirements of Rule 144, the Securities Act and the Exchange Act, (y) a copy of the most recent annual or quarterly
report of Holdings and such other reports and documents so filed by Holdings and (z) such other information as may be reasonably requested
to permit Subscriber to sell such securities pursuant to Rule 144 without registration.

 

c. Holdings
will use the proceeds from the sale of the Holdings Shares and the shares issued and sold pursuant to the Other Subscription Agreement
solely to finance the Transactions.

 

d. The
legend described in Section 5(e) shall be removed and Holdings shall issue a certificate without such legend to the holder of
the Holdings Shares upon which it is stamped or issue to such holder by electronic delivery at the applicable balance account at The
Depository Trust Company (“DTC”), if (i) such Holdings Shares are registered for resale under the Securities Act,
(ii) in connection with a sale, assignment or other transfer, such holder provides Holdings with an opinion of counsel, in a form reasonably
acceptable to Holdings, to the effect that such sale, assignment or transfer of the Holdings Shares may be made without registration
under the applicable requirements of the Securities Act, or (iii) the Holdings Shares can be sold, assigned or transferred pursuant to
Rule 144, and in each case, the holder provides Holdings with an undertaking to effect any sales or other transfers in accordance with
the Securities Act. Holdings shall be responsible for the fees of its transfer agent and all DTC fees associated with such issuance.

 

10. Miscellaneous.

 

a. Each
party hereto acknowledges that the other party hereto and others will rely on the acknowledgments, understandings, agreements, representations
and warranties contained in this Subscription Agreement. Prior to the Closing, each party hereto agrees to promptly notify the other
party hereto if any of the acknowledgments, understandings, agreements, representations and warranties set forth herein with respect
to it are no longer accurate in all material respects. Subscriber further acknowledges and agrees that each Placement Agent is a third-party
beneficiary of the representations and warranties of Subscriber contained in this Subscription Agreement. The Issuer, Holdings and Subscriber
acknowledge and agree that (i) the Company is a third-party beneficiary hereof and no consent, waiver, modification or amendment hereunder
or hereof may be given of agreed to by the Issuer or Holdings without the Company’s consent, (ii) this Subscription Agreement is
being entered into in order to induce each of the Issuer and the Company to execute and deliver the Merger Agreement and without the
representations, warranties, covenants and agreements of the Issuer and Subscriber hereunder, each of the Issuer and the Company would
not enter into the Merger Agreement, (iii) each representation, warranty, covenant and agreement of the Issuer and Subscriber hereunder
is being made also for the benefit of the Company and (d) the Company may directly enforce (including by an action for specific performance,
injunctive relief or other equitable relief) each of the covenants and agreements of each of the Issuer and Subscriber under this Subscription
Agreement.

 

b. Each
of the Issuer, Holdings and Subscriber is entitled to rely upon this Subscription Agreement and is irrevocably authorized to produce
this Subscription Agreement or a copy hereof to any interested party in any administrative or legal proceeding or official inquiry with
respect to the matters covered hereby. Each Placement Agent is entitled to rely upon the representations and warranties made by Subscriber
in this Subscription Agreement.

 

    16

     

    

 

c. Neither
this Subscription Agreement nor any rights, interests or obligations that may accrue to the parties hereunder (including Subscriber’s
rights to purchase the Acquired Shares) may be transferred or assigned without the prior written consent of each of the other parties
hereto (other than the Acquired Shares acquired hereunder, if any, and then only in accordance with this Subscription Agreement); provided,
however, that this Subscription Agreement and any of Subscriber’s rights and obligations hereunder may be assigned to any
affiliates of Subscriber or any fund or account managed by the same investment manager as Subscriber, without the prior consent of the
Issuer; provided, further, that such assignee(s) agrees in writing to be bound by the terms hereof. Upon such assignment
by a Subscriber, the assignee(s) shall become Subscriber hereunder and have the rights and obligations provided for herein to the extent
of such assignment; provided, further, that, no assignment shall relieve the assigning party of any of its obligations
hereunder, including any assignment to any fund or account managed by the same investment manager as Subscriber. Neither this Subscription
Agreement nor any rights that may accrue to the Issuer hereunder or any of the Issuer’s obligations may be transferred or assigned
other than pursuant to the Transactions.

 

d. All
the representations and warranties made by each party hereto in this Subscription Agreement shall survive the Closing. All covenants
made by each party hereto in this Subscription Agreement required to be performed after the Closing shall expire upon performance. All
other agreements made by each party hereto in this Subscription Agreement shall expire at the Closing.

 

e. The
Issuer may request from Subscriber such additional information as the Issuer may deem reasonably necessary to evaluate the eligibility
of Subscriber to acquire the Acquired Shares, and Subscriber shall provide such information as may be reasonably requested, to the extent
readily available and to the extent consistent with its internal policies and procedures and provided that the Issuer agrees to keep
any such information provided by Subscriber confidential; provided, however, that upon recipient of such additional information,
the Issuer shall be allowed to convey such information to each Placement Agent and such Placement Agent shall keep the information confidential,
except as may be required by applicable law, rule, regulation or in connection with any legal proceeding or regulatory request.

 

f. This
Subscription Agreement may not be modified, waived or terminated except by an instrument in writing, signed by the Company and the party
against whom enforcement of such modification, waiver, or termination is sought.

 

g. This
Subscription Agreement constitutes the entire agreement, and supersedes all other prior agreements, understandings, representations and
warranties, both written and oral, among the parties, with respect to the subject matter hereof.

 

h. Except
as otherwise provided herein, this Subscription Agreement shall be binding upon, and inure to the benefit of the parties hereto and their
heirs, executors, administrators, successors, legal representatives, and permitted assigns, and the agreements, representations, warranties,
covenants and acknowledgments contained herein shall be deemed to be made by, and be binding upon, such heirs, executors, administrators,
successors, legal representatives and permitted assigns.

 

i. If
any provision of this Subscription Agreement shall be invalid, illegal or unenforceable, the validity, legality or enforceability of
the remaining provisions of this Subscription Agreement shall not in any way be affected or impaired thereby and shall continue in full
force and effect.

 

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

 

k. Each
party shall pay all of its own expenses in connection with this Subscription Agreement and the transactions contemplated by this Subscription

understands and agrees that: (i) no disclosure or offering document has been prepared by either Placement Agent or any of their respective
affiliates in connection with the offer and sale of the Acquired Shares; (ii) each Placement Agent and its directors, officers, employees,
representatives and controlling persons have made no independent investigation with respect to the Issuer, the Company, the Transactions
or the Acquired Shares or the accuracy, completeness or adequacy of any information supplied to Subscriber by the Issuer; and (iii) in
connection with the issue and purchase of the Acquired Shares, neither Placement Agent has not acted as Subscriber’s financial
advisor, tax or fiduciary.

 

n.

o. 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 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 shall be entitled to 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, this being in addition to any other remedy to which such party is entitled at law, in equity, in contract, in
tort or otherwise. The right to specific enforcement shall include the right of the parties hereto to cause the other parties hereto
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 10(o)
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. The parties acknowledge and agree that this Section
10(o) is an integral part of the transactions contemplated hereby and without that right, the parties hereto would not have entered
into this Subscription Agreement.

 

p. 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 giving
effect to the principles of conflicts of laws thereof.

 

THE
PARTIES HERETO IRREVOCABLY SUBMIT TO THE EXCLUSIVE JURISDICTION OF 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
SOLELY IN RESPECT OF THE INTERPRETATION AND ENFORCEMENT OF THE PROVISIONS OF THIS SUBSCRIPTION AGREEMENT AND THE TRANSACTIONS CONTEMPLATED
HEREBY, AND HEREBY WAIVE, AND AGREE NOT TO ASSERT, AS A DEFENSE IN ANY ACTION, SUIT OR PROCEEDING FOR INTERPRETATION OR ENFORCEMENT HEREOF
OR THAT SUCH ACTION, SUIT OR PROCEEDING MAY NOT BE BROUGHT OR IS NOT MAINTAINABLE IN SAID COURTS OR THAT VENUE THEREOF MAY NOT BE APPROPRIATE
OR THAT THIS SUBSCRIPTION AGREEMENT MAY NOT BE ENFORCED IN OR BY SUCH COURTS, AND THE PARTIES HERETO IRREVOCABLY AGREE THAT ALL CLAIMS
WITH RESPECT TO SUCH ACTION, SUIT OR PROCEEDING SHALL BE HEARD AND DETERMINED BY SUCH A NEW YORK STATE OR FEDERAL COURT. THE PARTIES
HEREBY CONSENT TO AND GRANT ANY SUCH COURT JURISDICTION OVER THE PERSON OF SUCH PARTIES AND OVER THE SUBJECT MATTER OF SUCH DISPUTE AND
AGREE THAT MAILING OF PROCESS OR OTHER PAPERS IN CONNECTION WITH SUCH ACTION, SUIT OR PROCEEDING IN THE MANNER PROVIDED IN SECTION
10(n) OR IN SUCH OTHER MANNER AS MAY BE PERMITTED BY LAW SHALL BE VALID AND SUFFICIENT SERVICE THEREOF.

 

EACH
PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS SUBSCRIPTION AGREEMENT OR THE TRANSACTIONS CONTEMPLATED
HEREBY IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES

SUBSCRIPTION AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS SUBSCRIPTION AGREEMENT. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (I)

q. If,
any change in the Class A Shares shall occur between the date hereof and immediately prior to the Closing by reason of any reclassification,
recapitalization, stock split (including reverse stock split) or combination, exchange or readjustment of shares, or any stock dividend,
the number of Acquired Shares issued to Subscriber shall be appropriately adjusted to reflect such change.

 

    19

     

    

 

 

r. The
Issuer shall, by 9:00 a.m., New York City time, on the first (1st) business day immediately following the date of this Subscription Agreement,
issue one or more press releases or file with the Commission a Current Report on Form 8-K (collectively, the “Disclosure Document”)
disclosing all material terms of the transactions contemplated hereby and by the Other Subscription Agreements, the Transactions and
any other material, nonpublic information that the Issuer has provided to Subscriber at any time prior to the filing of the Disclosure
Document. Upon the issuance of the Disclosure Document, to the Issuer’s knowledge, Subscriber shall not be in possession of any
material, non-public information received from the Issuer or any of its officers, directors or employees or agents (including the Placement
Agent) and Subscriber shall no longer be subject to any confidentiality or similar obligations under any current agreement, whether written
or oral with the Issuer or any of its affiliates. Notwithstanding anything in this Subscription Agreement to the contrary, the Issuer
shall not publicly disclose the name of Subscriber or any of its affiliates, or include the name of Subscriber or any of its affiliates
in any press release or in any filing with the Commission or any regulatory agency or trading market, without the prior written consent
of Subscriber, except (i) as required by the federal securities law and (ii) to the extent such disclosure is required by law, at the
request of the Staff of the Commission or regulatory agency or under the regulations of Nasdaq.

 

s. The
obligations of Subscriber under this Subscription Agreement are several and not joint with the obligations of any Other Subscriber or
any other investor under the Other Subscription Agreements, and Subscriber shall not be responsible in any way for the performance of
the obligations of any Other Subscriber under this Subscription Agreement or any Other Subscriber or other investor under the Other Subscription
Agreements. Nothing contained herein or in any Other Subscription Agreement, and no action taken by Subscriber or investor pursuant hereto
or thereto, shall be deemed to constitute Subscriber and Other Subscribers or other investors as a partnership, an association, a joint
venture or any other kind of entity, or create a presumption that Subscriber and Other Subscribers or other investors are in any way
acting in concert or as a group with respect to such obligations or the transactions contemplated by this Subscription Agreement and
the Other Subscription Agreements. Subscriber shall be entitled to independently protect and enforce its rights, including without limitation
the rights arising out of this Subscription Agreement, and it shall not be necessary for any Other Subscriber or investor to be joined
as an additional party in any proceeding for such purpose..

 

11. Non-Reliance
and Exculpation.

 

Subscriber
acknowledges that it is not relying upon, and has not relied upon, any statement, representation, warranty or other information made
or provided by any person, firm or corporation (including, without limitation, the Placement Agents, any of their respective affiliates
or any control persons, officers, directors, employees, partners, agents or representatives of any of the foregoing), other than the
statements, representations expressly contained in Section 3 of this Subscription Agreement, in making its investment or decision
to invest. Subscriber acknowledges and agrees that, other than the statements, representations and warranties expressly contained in
Section 3 of this Subscription Agreement, none of (i) any other investor pursuant to this Subscription Agreement or any Other
Subscription Agreement (including the investor’s respective affiliates or any control persons, officers, directors, employees,
partners, agents or representatives of any of the foregoing) or (ii) the Placement Agents, their respective affiliates or any control
persons, officers, directors, employees, partners, agents or representatives of any of the foregoing shall have any liability to Subscriber,
or to any other investor, pursuant to, arising out of or relating to this Subscription Agreement or any Other Subscription Agreement,
the negotiation hereof or thereof or its subject matter, or the transactions contemplated hereby or thereby, including, without limitation,
with respect to any action heretofore or hereafter taken or omitted to be taken by any of them in connection with the purchase of the
Class A Shares or with respect to any claim (whether in tort, contract or otherwise) for breach of this Subscription Agreement or in
respect of any written or oral representations made or alleged to be made in connection herewith, as expressly provided herein, or for
any actual or alleged inaccuracies, misstatements or omissions with respect to any information or materials of any kind furnished by
the Issuer, Holdings, the Placement Agents or any Non-Party Affiliate (as defined below) concerning the Issuer, Holdings, the Placement
Agents, any of their respective controlled affiliates, this Subscription Agreement or the transactions contemplated hereby. For purposes
