ARTICLE II

REGISTRATIONS

 

2.1  Demand

2.1.1  Request
for Registration. Subject to the provisions of subsection 2.1.4 and Section 2.4 hereof, at any time and
from time to time on or after the date the Company consummates the Business Combination, the Holders of at least a majority in
interest of the then-outstanding number of Registrable Securities (the “Demanding Holders”) may make
a written demand for Registration of all or part of their Registrable Securities, which written demand shall describe the amount
and type of securities to be included in such Registration and the intended method(s) of distribution thereof (such written
demand a “Demand Registration”). The Company shall, within ten (10) days of the Company’s
receipt of the Demand Registration, notify, in writing, all other Holders of Registrable Securities of such demand, and each Holder
of Registrable Securities who thereafter wishes to include all or a portion of such Holder’s Registrable Securities in a
Registration pursuant to a Demand Registration (each such Holder that includes all or a portion of such Holder’s Registrable
Securities in such Registration, a “Requesting Holder”) shall so notify the Company, in writing, within
five (5) days after the receipt by the Holder of the notice from the Company. Upon receipt by the Company of any such written
notification from a Requesting Holder(s) to the Company, such Requesting Holder(s) shall be entitled to have their Registrable
Securities included in a Registration pursuant to a Demand Registration and the Company shall effect, as soon thereafter as practicable,
but not more than forty five (45) days immediately after the Company’s receipt of the Demand Registration, the Registration
of all Registrable Securities requested by the Demanding Holders and Requesting Holders pursuant to such Demand Registration. Under
no circumstances shall the Company be obligated to effect more than an aggregate of three (3) Registrations pursuant to a
Demand Registration under this subsection 2.1.1 with respect to any or all Registrable Securities; provided, however,
that a Registration shall not be counted for such purposes unless a Form S-1 or any similar long-form registration statement
that may be available at such time (“Form S-1”) has become effective and all of the Registrable
Securities requested by the Requesting Holders to be registered on behalf of the Requesting Holders in such Form S-1 Registration
have been sold, in accordance with Section 3.1 of this Agreement.

 

    	 	4	 

     

    

 

2.1.2  Effective
Registration. Notwithstanding the provisions of subsection 2.1.1 above or any other part of this Agreement,
a Registration pursuant to a Demand Registration shall not count as a Registration unless and until (i) the Registration Statement
filed with the Commission with respect to a Registration pursuant to a Demand Registration has been declared effective by the Commission
and (ii) the Company has complied with all of its obligations under this Agreement with respect thereto; provided, further,
that if, after such Registration Statement has been declared effective, an offering of Registrable Securities in a Registration
pursuant to a Demand Registration is subsequently interfered with by any stop order or injunction of the Commission, federal or
state court or any other governmental agency the Registration Statement with respect to such Registration shall be deemed not to
have been declared effective, unless and until, (i) such stop order or injunction is removed, rescinded or otherwise terminated,
and (ii) a majority-in-interest of the Demanding Holders initiating such Demand Registration thereafter affirmatively elect
to continue with such Registration and accordingly notify the Company in writing, but in no event later than five (5) days,
of such election; provided, further, that the Company shall not be obligated or required to file another
Registration Statement until the Registration Statement that has been previously filed with respect to a Registration pursuant
to a Demand Registration becomes effective or is subsequently terminated.

 

2.1.3  Underwritten
Offering. Subject to the provisions of subsection 2.1.4 and Section 2.4 hereof, if a majority-in-interest
of the Demanding Holders so advise the Company as part of their Demand Registration that the offering of the Registrable Securities
pursuant to such Demand Registration shall be in the form of an Underwritten Offering, then the right of such Demanding Holder
or Requesting Holder (if any) to include its Registrable Securities in such Registration shall be conditioned upon such Holder’s
participation in such Underwritten Offering and the inclusion of such Holder’s Registrable Securities in such Underwritten
Offering to the extent provided herein. All such Holders proposing to distribute their Registrable Securities through an Underwritten
Offering under this subsection 2.1.3 shall enter into an underwriting agreement in customary form with the Underwriter(s) selected
for such Underwritten Offering by the majority-in-interest of the Demanding Holders initiating the Demand Registration.

 

2.1.4  Reduction
of Underwritten Offering. If the managing Underwriter or Underwriters in an Underwritten Registration pursuant to a Demand
Registration, in good faith, advises the Company, the Demanding Holders and the Requesting Holders (if any) in writing 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 Common Stock or other equity securities that the Company desires to sell and the Common Stock, if
any, as to which a Registration has been requested pursuant to separate written contractual piggy-back registration rights held
by any other stockholders who desire to sell, 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, as
follows: (i) first, 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 Registration and the aggregate number of Registrable Securities that the Demanding Holders and Requesting
Holders have requested be included in such Underwritten Registration (such proportion is referred to herein as “Pro
Rata”)) that can be sold without exceeding the Maximum Number of Securities; (ii) second, to the extent that
the Maximum Number of Securities has not been reached under the foregoing clause (i), Common Stock or other equity securities that
the Company desires to sell, which can be sold without exceeding the Maximum Number of Securities; and (iii) third, to the
extent that the Maximum Number of Securities has not been reached under the foregoing clauses (i) and (ii), Common Stock or
other equity securities of other persons or entities that the Company is obligated to register in a Registration pursuant to separate
written contractual arrangements with such persons and that can be sold without exceeding the Maximum Number of Securities.

 

2.1.5  Demand
Registration Withdrawal. A majority-in-interest of the Demanding Holders initiating a Demand Registration or a
majority-in-interest of the Requesting Holders (if any), pursuant to a Registration under subsection
2.1.1 shall have the right to withdraw from a Registration pursuant to such Demand Registration for any or no reason
whatsoever upon written notification to the Company and the Underwriter or Underwriters (if any) of their intention to
withdraw from such Registration prior to the effectiveness of the Registration Statement filed with the Commission with
respect to the Registration of their Registrable Securities pursuant to such Demand Registration. Notwithstanding anything to
the contrary in this Agreement, the Company shall be responsible for the Registration Expenses incurred in connection with a
Registration pursuant to a Demand Registration prior to its withdrawal under this subsection 2.1.5.

2.2  Piggyback
Registration.

 

2.2.1  Piggyback
Rights. If, at any time on or after the date the Company consummates a Business Combination, the Company proposes to file a
Registration Statement under the Securities Act with respect to an offering 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, pursuant to Section 2.1 hereof),
other than a Registration Statement (i) filed in connection with any employee stock option or other benefit plan, (ii) for
an exchange offer or offering of securities solely to the Company’s existing stockholders, (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 filing to all of the Holders of Registrable Securities as soon as practicable but not
less than ten (10) days before the anticipated filing date of such Registration Statement, 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 register the sale of such number of Registrable Securities as such Holders may request in writing
within five (5) days after receipt of such written notice (such Registration a “Piggyback Registration”).
The Company shall, in good faith, cause such Registrable Securities to be included in such Piggyback Registration and shall use
its best efforts to cause the managing Underwriter or Underwriters of a proposed Underwritten Offering to permit the Registrable
Securities requested by the Holders pursuant to this subsection 2.2.1 to be included in a Piggyback Registration
on the same terms and conditions as any similar securities of the Company included in such Registration and to permit the sale
or other disposition of such Registrable Securities in accordance with the intended method(s) of distribution thereof. All
such Holders proposing to distribute their Registrable Securities through an Underwritten Offering under this subsection
2.2.1 shall enter into an underwriting agreement in customary form with the Underwriter(s) selected for such Underwritten
Offering by the Company.

 

2.2.2  Reduction
of Piggyback Registration. If the managing Underwriter or Underwriters in an Underwritten Registration that is to be a Piggyback
Registration, in good faith, advises the Company and the Holders of Registrable Securities participating in the Piggyback Registration
in writing that the dollar amount or number of shares of Common Stock that the Company desires to sell, taken together with (i) the
shares of Common Stock, if any, as to which Registration has been demanded pursuant to separate written contractual arrangements
with persons or entities other than the Holders of Registrable Securities hereunder, (ii) the Registrable Securities as to
which registration has been requested pursuant to Section 2.2 hereof, and (iii) the shares of Common
Stock, if any, as to which Registration has been requested pursuant to separate written contractual piggy-back registration rights
of other stockholders of the Company, exceeds the Maximum Number of Securities, then:

 

(a)    If
the Registration is undertaken for the Company’s account, the Company shall include in any such Registration (A) first,
Common Stock or other equity securities that the Company desires to sell, which can be sold without exceeding the Maximum Number
of Securities; (B) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause
(A), the Registrable Securities of Holders exercising their rights to register their Registrable Securities pursuant to subsection
2.2.1 hereof, Pro Rata, which can be sold without exceeding the Maximum Number of Securities; and (C) third, to the
extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A) and (B), Common Stock, if
any, as to which Registration has been requested pursuant to written contractual piggy-back registration rights of other stockholders
of the Company, which can be sold without exceeding the Maximum Number of Securities;

 

(b)    If
the Registration is pursuant to a request by persons or entities other than the Holders of Registrable Securities, then the Company
shall include in any such Registration (A) first, Common Stock or other equity securities, if any, of such requesting persons
or entities, other than the Holders of Registrable Securities, which can be sold without exceeding the Maximum Number of Securities;
(B) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (A), the
Registrable Securities of Holders exercising their rights to register their Registrable Securities pursuant to subsection
2.2.1, pro rata based on the number of Registrable Securities that each Holder has requested be included in such Underwritten
Registration and the aggregate number of Registrable Securities that the Holders have requested to be included in such Underwritten
Registration, which can be sold without exceeding the Maximum Number of Securities; (C) third, to the extent that the Maximum
Number of Securities has not been reached under the foregoing clauses (A) and (B), Common Stock or other equity securities
that the Company desires to sell, which can be sold without exceeding the Maximum Number of Securities; and (D) fourth, to
the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A), (B) and (C), Common
Stock or other equity securities for the account of other persons or entities that the Company is obligated to register pursuant
to separate written contractual arrangements with such persons or entities, which can be sold without exceeding the Maximum Number

2.2.3  Piggyback
Registration Withdrawal. Any Holder of Registrable Securities shall have the right to withdraw from a Piggyback Registration
for any or no reason whatsoever upon written notification to the Company and the Underwriter or Underwriters (if any) of his, her
or its intention to withdraw from such Piggyback Registration prior to the effectiveness of the Registration Statement filed with
the Commission with respect to such Piggyback Registration. The Company (whether on its own good faith determination or as the
result of a request for withdrawal by persons pursuant to separate written contractual obligations) may withdraw a Registration
Statement filed with the Commission in connection with a Piggyback Registration at any time prior to the effectiveness of such
Registration Statement. Notwithstanding anything to the contrary in this Agreement, the Company shall be responsible for the Registration
Expenses incurred in connection with the Piggyback Registration prior to its withdrawal under this subsection 2.2.3.

 

2.2.4  Unlimited
Piggyback Registration Rights. For purposes of clarity, any Registration effected pursuant to Section 2.2 hereof
shall not be counted as a Registration pursuant to a Demand Registration effected under Section 2.1 hereof.

 

2.3  Registrations
on Form S-3. The Holders of Registrable Securities may at any time, and from time to time, request in writing that the
Company, pursuant to Rule 415 under the Securities Act (or any successor rule promulgated thereafter by the Commission),
register the resale of any or all of their Registrable Securities on Form S-3 or any similar short form registration statement
that may be available at such time (“Form S-3”); provided, however, that
the Company shall not be obligated to effect such request through an Underwritten Offering. Within five (5) days of the Company’s
receipt of a written request from a Holder or Holders of Registrable Securities for a Registration on Form S-3, the Company
shall promptly give written notice of the proposed Registration on Form S-3 to all other Holders of Registrable Securities,
and each Holder of Registrable Securities who thereafter wishes to include all or a portion of such Holder’s Registrable
Securities in such Registration on Form S-3 shall so notify the Company, in writing, within ten (10) days after the receipt
by the Holder of the notice from the Company. As soon as practicable thereafter, but not more than twelve (12) days after the Company’s
initial receipt of such written request for a Registration on Form S-3, the Company shall register all or such portion of
such Holder’s Registrable Securities as are specified in such written request, together with all or such portion of Registrable
Securities of any other Holder or Holders joining in such request as are specified in the written notification given by such Holder
or Holders; provided, however, that the Company shall not be obligated to effect any such Registration
pursuant to Section 2.3 hereof if (i) a Form S-3 is not available for such offering; or (ii) the
Holders of Registrable Securities, together with the Holders of any other equity securities of the Company entitled to inclusion
in such Registration, propose to sell the Registrable Securities and such other equity securities (if any) at any aggregate price
to the public of less than $10,000,000.

 

2.4  Restrictions
on Registration Rights. If (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 has delivered written notice to the Holders prior to receipt
of a Demand Registration pursuant to subsection 2.1.1 and it continues to actively employ, in good faith, all
reasonable efforts to cause the applicable Registration Statement to become effective; (B) the Holders have requested an
Underwritten Registration and the Company and the Holders are unable to obtain the commitment of underwriters to firmly underwrite
the offer; or (C) in the good faith judgment of the Board such Registration would be seriously detrimental to the Company
and the Board concludes as a result that it is essential to defer the filing of such Registration Statement at such time, then
in each case the Company shall furnish to such Holders a certificate signed by the Chairman of the Board stating that in the good
faith judgment of the Board it would be seriously detrimental to the Company for such Registration Statement to be filed in the
near future and that it is therefore essential to defer the filing of such Registration Statement. In such event, the Company
shall have the right to defer such filing for a period of not more than thirty (30) days; provided, however, that
the Company shall not defer its obligation in this manner more than once in any 12 month period. Notwithstanding anything to the
contrary contained in this Agreement, no Registration shall be effected or permitted and no Registration Statement shall become
effective, with respect to any Registrable Securities held by any Holder, until after the expiration of the Founder Shares Lock-Up
Period or the Private Placement Lock-Up Period, as the case may be.

Prospectus, furnish a copy thereof to each seller of such Registrable Securities or its counsel;

 

3.1.9  notify
the Holders 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,

to participate, at each such person’s own expense, in the preparation of the Registration Statement, and cause the Company’s

or accountant in connection with the Registration; provided, however, that such representatives or Underwriters

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, 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, 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, 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

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  if
the Registration involves the Registration of Registrable Securities involving gross proceeds in excess of $50,000,000, use its
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 any 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, in connection
with such Registration.

 

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

the definition of “Registration Expenses,” all reasonable fees and expenses of any legal counsel representing the
Holders.

3.3  Requirements
for Participation in Underwritten Offerings. 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.

 

3.4  Suspension
of Sales; Adverse Disclosure. 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 he, she or 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 he, she or it
is advised in writing by the Company that the use of the Prospectus may be resumed. If the filing, initial effectiveness or continued
use of a Registration Statement in respect of any Registration at any time would require the Company to make an Adverse Disclosure
or would require the inclusion in such Registration Statement of financial statements that are unavailable to the Company for reasons
beyond the Company’s control, the Company may, upon giving prompt written notice of such action to the Holders, delay the
filing or initial effectiveness of, or suspend use of, such Registration Statement for the shortest period of time, but in no event
more than thirty (30) days, determined in good faith by the Company to be necessary for such purpose. In the event the Company
exercises its rights under the preceding sentence, 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.
The Company shall immediately notify the Holders of the expiration of any period during which it exercised its rights under this Section 3.4.

 

3.5  Reporting
Obligations. As long as any Holder shall own 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 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 Common Stock held by such Holder without registration under the Securities Act within the limitation
of the exemptions provided by Rule 144 promulgated under the Securities Act (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
a written certification of a duly authorized officer as to whether it has complied with such requirements.

 

ARTICLE IV

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, its officers and directors
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) caused by 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.

 

    	 	10	 

     

    

 

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 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 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.

 

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 subsection 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 subsections
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 subsection 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 subsection 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 subsection 4.1.5 from any person who was not guilty of such fraudulent misrepresentation.

Nebula
Acquisition Corporation

480 Pacific Avenue, Suite 200

San Francisco, CA 94133

 

Re:
Initial Public Offering

 

Gentlemen:

 

This
letter (this “Letter Agreement”) is being delivered to you in accordance with the Underwriting Agreement
(the “Underwriting Agreement”) to be entered into by and among Nebula Acquisition Corporation, a Delaware
corporation (the “Company”), Deutsche Bank Securities Inc. and Goldman, Sachs & Co., as representatives
(the “Representatives”) of the several underwriters (each, an “Underwriter”
and collectively, the “Underwriters”), relating to an underwritten initial public offering (the “Public
Offering”), of 28,750,000 of the Company’s units (including up to 3,750,000 units that may be purchased to
cover over-allotments, if any) (the “Units”), each comprised of one share of the Company’s Class A
common stock, par value $0.0001 per share (the “Common Stock”), and one-third of one warrant. Each whole
Warrant (each, a “Warrant”) entitles the holder thereof to purchase one share of Common Stock at a price
of $11.50 per share, subject to adjustment. The Units shall be sold in the Public Offering pursuant to a registration statement
on Form S-1 and prospectus (the “Prospectus”) filed by the Company with the Securities and Exchange
Commission (the “Commission”) and the Company shall apply to have the Units listed on the Nasdaq Capital
Market. Certain capitalized terms used herein are defined in paragraph 11 hereof.

 

In
order to induce the Company and the Underwriters to enter into the Underwriting Agreement and to proceed with the Public Offering
and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Nebula Holdings,
LLC (the “Sponsor”) and each of the undersigned individuals, each of whom is a member of the Company’s
board of directors and/or management team (each, an “Insider” and collectively, the “Insiders”),
hereby agrees with the Company as follows:

 

1. 
The Sponsor and each Insider agrees that if the Company seeks stockholder approval of a proposed Business Combination, then in
connection with such proposed Business Combination, it, he or she shall (i) vote any shares of Capital Stock owned by it,
him or her in favor of any proposed Business Combination and (ii) not redeem any shares of Common Stock owned by it, him
or her in connection with such stockholder approval.

 

2. 
The Sponsor and each Insider hereby agrees that in the event that the Company fails to consummate a Business Combination within
24 months from the closing of the Public Offering , or such later period approved by the Company’s stockholders in accordance
with the Company’s amended and restated certificate of incorporation, the Sponsor and each Insider shall take all reasonable
steps to cause the Company to (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably
possible but not more than 10 business days thereafter, subject to lawfully available funds therefor, redeem 100% of the Common
Stock sold as part of the Units in the Public Offering (the “Offering Shares”), at a per-share price,
payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held
in the Trust Account and not previously released to the Company to pay its franchise and income taxes and up to $500,000 that
may be released to the Company for working capital purposes (less up to $100,000 of interest to pay dissolution expenses), divided
by the number of then outstanding Offering Shares, which redemption will completely extinguish all Public Stockholders’
rights as stockholders (including the right to receive further liquidation distributions, if any), subject to applicable law,
and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining
stockholders and the Company’s board of directors, dissolve and liquidate, subject in each case to the Company’s obligations
under Delaware law to provide for claims of creditors and other requirements of applicable law. The Sponsor and each Insider agree
not to propose any amendment to the Company’s amended and restated certificate of incorporation that would modify the substance
or timing of the Company’s obligation to redeem 100% of the Offering Shares if the Company does not complete a Business
Combination within 24 months from the closing of the Public Offering, unless the Company provides its Public Stockholders with
the opportunity to redeem their Offering Shares upon approval of any such amendment at a per-share price, payable in cash, equal
to the aggregate amount then on deposit in the Trust Account, including interest (which interest shall be net of amounts released
for payment of taxes and up to $500,000 for working capital released to the Company) divided by the number of then outstanding
Offering Shares.

 

     

    

    

 

The
Sponsor and each Insider acknowledges that it, he or she has no right, title, interest or claim of any kind in or to any monies
held in the Trust Account or any other asset of the Company as a result of any liquidation of the Company with respect to the
Founder Shares held by it, him or her. The Sponsor and each Insider hereby further waives, with respect to any shares of Common
Stock held by it, him or her, if any, any redemption rights it, he or she may have in connection with the consummation of a Business
Combination, including, without limitation, any such rights available in the context of a stockholder vote to approve such Business
Combination or in the context of a tender offer made by the Company to purchase shares of Common Stock (although the Sponsor,
the Insiders and their respective affiliates shall be entitled to redemption and liquidation rights with respect to any Offering
Shares it or they hold if the Company fails to consummate a Business Combination within 24 months from the date of the closing
of the Public Offering).

 

3. 
During the period commencing on the effective date of the Underwriting Agreement and ending 180 days after such date, the Sponsor
and each Insider shall not, without the prior written consent of the Representatives, (i) sell, offer to sell, contract or
agree to sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree to dispose of, directly or indirectly,
or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16
of the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission promulgated thereunder,
with respect to any Units, shares of Capital Stock, Warrants or any securities convertible into, or exercisable, or exchangeable
for, shares of Common Stock owned by it, him or her, (ii) enter into any swap or other arrangement that transfers to another,
in whole or in part, any of the economic consequences of ownership of any Units, shares of Capital Stock, Warrants or any securities
convertible into, or exercisable, or exchangeable for, shares of Common Stock owned by it, him or her, whether any such transaction
is to be settled by delivery of such securities, in cash or otherwise, or (iii) publicly announce any intention to effect
any transaction specified in clause (i) or (ii). Each of the Insiders and the Sponsor acknowledges and agrees that, prior
to the effective date of any release or waiver of the restrictions set forth in this paragraph 3 or paragraph 7 below, the Company
shall announce the impending release or waiver by press release through a major news service at least two business days before
the effective date of the release or waiver. Any release or waiver granted shall only be effective two business days after the
publication date of such press release. The provisions of this paragraph will not apply if (i) the release or waiver is effected
solely to permit a transfer of securities that is not for consideration and (ii) the transferee has agreed in writing to be bound
by the same terms described in this Letter Agreement to the extent and for the duration that such terms remain in effect at the
time of the transfer.

 

4. 
In the event of the liquidation of the Trust Account, the Sponsor (which for purposes of clarification shall not extend to any
other shareholders, members or managers of the Sponsor) agrees to indemnify and hold harmless the Company against any and all
loss, liability, claim, damage and expense whatsoever (including, but not limited to, any and all legal or other expenses reasonably
incurred in investigating, preparing or defending against any litigation, whether pending or threatened, or any claim whatsoever)
to which the Company may become subject as a result of any claim by (i) any third party (other than the Company’s independent
accountants) for services rendered or products sold to the Company or (ii) a prospective target business with which the Company
has entered into a letter of intent, confidentiality or other similar agreement for a Business Combination agreement (a “Target”);
provided, however, that such indemnification of the Company by the Sponsor shall apply only to the extent necessary
to ensure that such claims by a third party for services rendered (other than the Company’s independent public accountants)
or products sold to the Company or a Target do not reduce the amount of funds in the Trust Account to below (i) $10.00 per
share of the Offering Shares or (ii) such lesser amount per share of the Offering Shares held in the Trust Account due to
reductions in the value of the trust assets as of the date of the liquidation of the Trust Account, in each case, net of the amount
of interest earned on the property in the Trust Account which may be withdrawn to pay taxes, and up to $500,000 for working capital
purposes, except as to any claims by a third party (including a Target) who executed a waiver of any and all rights to seek access
to the Trust Account and except as to any claims under the Company’s indemnity of the Underwriters against certain liabilities,
including liabilities under the Securities Act of 1933, as amended. In the event that any such executed waiver is deemed to be
unenforceable against such third party, the Sponsor shall not be responsible to the extent of any liability for such third party
claims. The Sponsor shall have the right to defend against any such claim with counsel of its choice reasonably satisfactory to
the Company if, within 15 days following written receipt of notice of the claim to the Sponsor, the Sponsor notifies the Company
in writing that it shall undertake such defense.

 

    	 	2	 

    

    

 

5. 
To the extent that the Underwriters do not exercise their over-allotment option to purchase up to an additional 3,750,000 Units
within 45 days from the date of the Prospectus (and as further described in the Prospectus), the Sponsor agrees to forfeit, at
no cost, a number of Founder Shares in the aggregate equal to the product of 937,500 multiplied by a fraction, (i) the numerator
of which is 3,750,000 minus the number of Units purchased by the Underwriters upon the exercise of their over-allotment option,
and (ii) the denominator of which is 3,750,000. The forfeiture will be adjusted to the extent that the over-allotment option
is not exercised in full by the Underwriters so that the Initial Stockholders will own an aggregate of 20.0% of the Company’s
issued and outstanding shares of Capital Stock after the Public Offering.

 

6. 
(a)  The Sponsor and each Insider who is an officer of the Company hereby agrees not to participate in the formation of,
or become an officer or director of, any other blank check company unless the Company has failed to complete a Business Combination
within 24 months after the closing of the Public Offering. Such restriction does not preclude any position as an officer or director
of another blank check company held on the date hereof. For the avoidance of doubt, the Sponsor and each Insider who is an officer
of the Company are allowed to participate in the formation of, or become an officer or director of, another blank check company
upon the Company entering into a definitive agreement with respect to a Business Combination.

 

(b) 
The Sponsor and each Insider hereby agrees and acknowledges that: (i) the Underwriters and the Company would be irreparably
injured in the event of a breach by such Sponsor or an Insider of its, his or her obligations under paragraphs 1, 2, 3, 4, 5,
6(a), 7(a), 7(b), and 9 of this Letter Agreement (ii) monetary damages may not be an adequate remedy for such breach and
(iii) the non-breaching party shall be entitled to injunctive relief, in addition to any other remedy that such party may
have in law or in equity, in the event of such breach.

 

7. 
(a)  The Sponsor and each Insider agrees that it or he shall not Transfer any Founder Shares (or shares of Common Stock issuable
upon conversion thereof) until the earlier of (A) one year after the completion of the Company’s initial Business Combination
or (B) subsequent to the Business Combination, (x) if 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) for any 20 trading
days within any 30-trading day period commencing at least 150 days after the Company’s initial Business Combination or (y) the
date on which the Company completes a liquidation, merger, capital stock exchange, reorganization or other similar transaction
that results in all of the Company’s stockholders having the right to exchange their shares of Common Stock for cash, securities
or other property (the “Founder Shares Lock-up Period”).

 

(b) 
The Sponsor and each Insider agrees that it, he or she shall not Transfer any Private Placement Warrants (or shares of Common
Stock issued or issuable upon the exercise of the Private Placement Warrants) until 30 days after the completion of a Business
Combination (the “Private Placement Warrants Lock-up Period”, together with the Founder Shares Lock-up
Period, the “Lock-up Periods”).

 

(c) 
Notwithstanding the provisions set forth in paragraphs 7(a) and (b), Transfers of the Founder Shares, Private Placement Warrants
and shares of Common Stock issued or issuable upon the exercise or conversion of the Private Placement Warrants or the Founder
Shares and that are held by the Sponsor, any Insider or any of their permitted transferees (that have complied with this paragraph
7(c)), are permitted (a) to the Company’s officers or directors, any affiliates or family members of any of the Company’s
officers or directors, any members of the Sponsor, or any affiliates of the Sponsor; (b) in the case of an individual, by
gift to a member of the individual’s immediate family, to a trust, the beneficiary of which is a member of the individual’s
immediate family or an affiliate of such person, or to a charitable organization; (c) in the case of an individual, transfers
by virtue of laws of descent and distribution upon death of the individual; (d) in the case of an individual, transfers pursuant
to a qualified domestic relations order; (e) transfers by private sales or transfers made in connection with the consummation
of a Business Combination at prices no greater than the price at which the securities were originally purchased; (f) transfers
in the event of the Company’s liquidation prior to the completion of an initial Business Combination; (g) transfers
by virtue of the laws of the State of Delaware or the Sponsor’s limited liability company agreement upon dissolution of
the Sponsor; and (h) in the event of the Company’s liquidation, merger, capital stock exchange, reorganization or other
similar transaction which results in all of the Company’s stockholders having the right to exchange their shares of Common
Stock for cash, securities or other property subsequent to the completion of the Company’s initial Business Combination;
provided, however, that in the case of clauses (a) through (h), these permitted transferees must enter into a written agreement
agreeing to be bound by the restrictions herein.

8. 
The Sponsor and each Insider represents and warrants that it, he or she has never been suspended or expelled from membership in
any securities or commodities exchange or association or had a securities or commodities license or registration denied, suspended
or revoked. Each Insider’s biographical information furnished to the Company (including any such information included in
the Prospectus) is true and accurate in all respects and does not omit any material information with respect to the Insider’s
background. The Sponsor and each Insider’s questionnaire furnished to the Company is true and accurate in all respects.
The Sponsor and each Insider represents and warrants that: it, he or she is not subject to or a respondent in any legal action
for, any injunction, cease-and-desist order or order or stipulation to desist or refrain from any act or practice relating to
the offering of securities in any jurisdiction; it, he or she has never been convicted of, or pleaded guilty to, any crime (i) involving
fraud, (ii) relating to any financial transaction or handling of funds of another person, or (iii) pertaining to any
dealings in any securities and it, he or she is not currently a defendant in any such criminal proceeding.

 

9. 
(a) Except as disclosed in the Prospectus, neither the Sponsor nor any Insider nor any affiliate of the Sponsor or any Insider,
nor any director or officer of the Company, shall receive from the Company any finder’s fee, reimbursement, consulting fee,
monies in respect of any repayment of a loan or other compensation prior to, or in connection with any services rendered in order
to effectuate the consummation of the Company’s initial Business Combination (regardless of the type of transaction that
it is), other than the following, none of which will be made from the proceeds held in the Trust Account prior to the completion
of the initial Business Combination: repayment of a loan and advances up to an aggregate of $300,000 made to the Company by the
Sponsor; reimbursement for any out-of-pocket expenses related to identifying, investigating and consummating an initial Business
Combination; and repayment of loans, if any, and on such terms as to be determined by the Company from time to time, made by the
Sponsor or any of the Company’s officers or directors to finance transaction costs in connection with an intended initial
Business Combination, provided, that, if the Company does not consummate an initial Business Combination, a portion of the working
capital held outside the Trust Account may be used by the Company to repay such loaned amounts so long as no proceeds from the
Trust Account are used for such repayment. Up to $1,500,000 of such loans may be convertible into warrants at a price of $1.50
per warrant at the option of the lender. Such warrants would be identical to the Private Placement Warrants, including as to exercise
price, exercisability and exercise period.

 

(b)
Commencing on the effective date of the Prospectus for the Public Offering and continuing until the earlier of (i) the consummation
by the Company of a Business Combination or (ii) the Company’s liquidation as described in the Prospectus, True Wind Capital,
L.P. shall make available to the Company, at no charge, certain office space and administrative and support services as may be
required by the Company from time to time, situated at Four Embarcadero Center, Suite 2350, San Francisco, CA 94111 (or any successor
locations).

 

10. 
The Sponsor and each Insider has full right and power, without violating any agreement to which it is bound (including, without
limitation, any non-competition or non-solicitation agreement with any employer or former employer), to enter into this Letter
Agreement and, as applicable, to serve as an officer and/or a director on the board of directors of the Company and hereby consents
to being named in the Prospectus as an officer and/or a director of the Company.

12.
This Letter Agreement constitutes the entire agreement and understanding of the parties hereto in respect of the subject matter
hereof and supersedes all prior understandings, agreements, or representations by or among the parties hereto, written or oral,
to the extent they relate in any way to the subject matter hereof or the transactions contemplated hereby. This Letter Agreement
may not be changed, amended, modified or waived (other than to correct a typographical error) as to any particular provision,
except by a written instrument executed by all parties hereto.

 

13.
No party hereto may assign either this Letter Agreement or any of its rights, interests, or obligations hereunder without the
prior written consent of the other parties. Any purported assignment in violation of this paragraph shall be void and ineffectual
and shall not operate to transfer or assign any interest or title to the purported assignee. This Letter Agreement shall be binding
on the Sponsor and each Insider and their respective successors, heirs and assigns and permitted transferees.

 

14.
Nothing in this Letter Agreement shall be construed to confer upon, or give to, any person or corporation other than the parties
hereto any right, remedy or claim under or by reason of this Letter Agreement or of any covenant, condition, stipulation, promise
or agreement hereof. All covenants, conditions, stipulations, promises and agreements contained in this Letter Agreement shall
be for the sole and exclusive benefit of the parties hereto and their successors, heirs, personal representatives and assigns
and permitted transferees.

for all purposes be deemed to be an original, and all such counterparts shall together constitute but one and the same instrument.

 

16.
This Letter Agreement shall be deemed severable, and the invalidity or unenforceability of any term or provision hereof shall
not affect the validity or enforceability of this Letter Agreement or of any other term or provision hereof. Furthermore, in lieu
of any such invalid or unenforceable term or provision, the parties hereto intend that there shall be added as a part of this
Letter Agreement a provision as similar in terms to such invalid or unenforceable provision as may be possible and be valid and
enforceable.

 

17.
This Letter Agreement shall be governed by and construed and enforced in accordance with the laws of the State of New York, without
giving effect to conflicts of law principles that would result in the application of the substantive laws of another jurisdiction.
The parties hereto (i) all agree that any action, proceeding, claim or dispute arising out of, or relating in any way to, this
Letter Agreement shall be brought and enforced in the courts of New York City, in the State of New York, and irrevocably submit
to such jurisdiction and venue, which jurisdiction and venue shall be exclusive and (ii) waive any objection to such exclusive
jurisdiction and venue or that such courts represent an inconvenient forum.

Any notice, consent or request to be given in connection with any of the terms or provisions of this Letter Agreement shall be
in writing and shall be sent by express mail or similar private courier service, by certified mail (return receipt requested),
by hand delivery or facsimile transmission.
