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.

 

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

any time on or after the date the Company consummates a Business Combination, the Company proposes to file a Registration Statement

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

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

it would be seriously detrimental to the Company for such Registration Statement to be filed in the near future and that it is

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.

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

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

3.1.6 provide a transfer agent or warrant

3.1.7 advise each seller of such Registrable

or any document that is to be incorporated by reference into such Registration Statement or Prospectus, furnish a copy thereof

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, 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
(such representative to be selected by a majority of the participating Holders), the Underwriters, if any, and any attorney or
accountant retained by such Holders 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 enter into a confidentiality agreement, in form and substance 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, 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,

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 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.

 

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 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. 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 the 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.

 

3.6  Limitations
on Registration Rights. Notwithstanding anything herein to the contrary, (i) CF & Co. may not exercise its rights under
Sections 2.1 and 2.2 hereunder after five (5) and seven (7) years after the effective date of the registration statement relating
to the Company’s initial public offering, respectively, and (ii) CF & Co. may not exercise its rights under Section 2.1
more than one time.

 

     

     

    

 

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.

 

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.

PRIVATE PLACEMENT WARRANTS PURCHASE AGREEMENT

 

THIS  PRIVATE PLACEMENT WARRANTS PURCHASE
AGREEMENT, dated as of January 15, 2018 (as it may from time to time be amended and including all exhibits referenced herein, this
“Agreement”), is entered into by and between Mudrick Capital Acquisition Corporation, a Delaware corporation
(the “Company”), and Mudrick Capital Acquisition Holdings LLC, a Delaware limited liability company (the “Purchaser”).

 

WHEREAS, the Company intends to consummate an
initial public offering of the Company’s units (the “Public Offering”), each unit consisting of one share
of the Company’s Class A common stock, par value $0.0001 per share (each, a “Share”), and one redeemable
warrant. Each warrant entitles the holder to purchase one Share at an exercise price of $11.50 per Share. The Purchaser has agreed
to purchase an aggregate of 6,500,000 warrants (or up to 7,250,000 warrants if the over-allotment option in connection with the
Public Offering is exercised in full) (the “Private Placement Warrants”), each Private Placement Warrant entitling
the holder to purchase one Share at an exercise price of $11.50 per Share.

 

NOW THEREFORE, in consideration of the mutual
promises contained in this Agreement and other good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties to this Agreement hereby, intending legally to be bound, agree as follows:

 

AGREEMENT

 

Section 1. Authorization, Purchase and
Sale; Terms of the Private Placement Warrants.

 

A. Authorization of the Private Placement
Warrants. The Company has duly authorized the issuance and sale of the Private Placement Warrants to the Purchaser.

 

B. Purchase and Sale of the Private

On the date of the consummation of the Public
Offering, and concurrently with the consummation thereof, or on such earlier time and date as may be mutually agreed by the Purchaser
and the Company (the “Initial Closing Date”), the Company shall issue and sell to the Purchaser, and the Purchaser
shall purchase from the Company 6,500,000 Private Placement Warrants at a price of $1.00 per warrant for an aggregate purchase
price of $6,500,000 (the “Purchase Price”). The Purchase Price shall be paid by wire transfer of immediately
available funds to the Company in accordance with the Company’s wiring instructions at least one business day prior to the
date of effectiveness of the registration statement to be filed in connection with the Public Offering. On the Initial Closing
Date, the Company, shall either, at its option, deliver a certificate evidencing the Private Placement Warrants purchased by the
Purchaser on such date duly registered in the Purchaser’s name to the Purchaser, or effect such delivery in book-entry form.
On the date of the consummation of the closing of the over-allotment option in connection with the Public Offering, and concurrently
with the consummation thereof, or on such earlier time and date as may be mutually agreed by the Purchaser and the Company (each
such date, an “Over-allotment Closing Date,” and each Over-allotment Closing Date (if any) and the Initial Closing
Date being sometimes referred to herein as a “Closing Date”), the Company shall issue and sell to the Purchaser,
and the Purchaser shall purchase from the Company, up to an aggregate of 750,000 Private Placement Warrants, in the same proportion
as the amount of the over-allotment option that is exercised, at a price of $1.00 per warrant for an aggregate purchase price of
up to $750,000 (if the over-allotment option in connection with the Public Offering is exercised in full) (the “Over-allotment
Purchase Price”), which shall be paid by wire transfer of immediately available funds to the Company in accordance with
the Company’s wiring instructions. On the Over-allotment Closing Date, upon the payment by the Purchaser of the Over-allotment
Purchase Price payable by it by wire transfer of immediately available funds to the Company, the Company shall either, at its option,
deliver a certificate evidencing the Private Placement Warrants purchased by the Purchaser on such date duly registered in the
Purchaser’s name to the Purchaser, or effect such delivery in book-entry form.

 

     

     

    

 

C. Terms of the Private Placement Warrants.

 

(i) The Private Placement Warrants shall have
their terms set forth in a Warrant Agreement to be entered into by the Company and a warrant agent, in connection with the Public
Offering (a “Warrant Agreement”).

 

(ii) At or prior to the time of the Initial
Closing Date, the Company and the Purchaser shall enter into a registration rights agreement (the “Registration Rights
Agreement”) pursuant to which the Company will grant certain registration rights to the Purchaser relating to the Private
Placement Warrants and the Shares underlying the Private Placement Warrants.

 

Section 2. Representations and Warranties

Closing Date) that:

(ii) The execution and delivery by the Company
of this Agreement and the Private Placement Warrants, the issuance and sale of the Private Placement Warrants, the issuance of

and thereof by the Company, do not and will not as of each Closing Date (a) conflict with or result in a breach of the terms,

to which the Company is subject, or any agreement, order, judgment or decree to which the Company is subject, except for any filings

in accordance with, and payment pursuant to, the terms hereof and the Warrant Agreement, the Placement Warrants will be duly and
validly issued and the Shares issuable upon exercise of the Private Placement Warrants will be duly and validly issued, fully paid

Agreement, the Purchaser will have good title to the Private Placement Warrants and the Shares issuable upon exercise of such Private
Placement Warrants, free and clear of all liens, claims and encumbrances of any kind, other than (i) transfer restrictions
hereunder and under the other agreements contemplated hereby, (ii) transfer restrictions under federal and state securities
laws, and (iii) liens, claims or encumbrances imposed due to the actions of the Purchaser.

preferred stock, par value $0.0001,

 

     

     

    

 

per share (the “Preferred Stock”).
As of the date hereof, the Company has issued and outstanding no shares of Class A Common Stock, 5,750,000 shares of Class B Common
Stock (of which up to 750,000 shares are subject to forfeiture as described in the Registration Statement) and no shares of Preferred
Stock. All of the issued shares of capital stock of the Company have been duly authorized, validly issued, and are fully paid and
non-assessable.

 

E. Governmental Consents. No permit,
consent, approval or authorization of, or declaration to or filing with, any governmental authority is required in connection with
the execution, delivery and performance by the Company of this Agreement or the consummation by the Company of any other transactions
contemplated hereby.

 

Section 3. Representations and Warranties
of the Purchaser. As a material inducement to the Company to enter into this Agreement and issue and sell the Private
Placement Warrants to the Purchaser, the Purchaser hereby represents and warrants to the Company (which representations and warranties
shall survive each Closing Date) that: 

 

A. Organization and Requisite Authority.
The Purchaser possesses all requisite power and authority necessary to carry out the transactions contemplated by this Agreement.

 

B. Authorization; No Breach.

 

(i) This Agreement constitutes a valid and binding
obligation of the Purchaser, enforceable in accordance with its terms, subject to bankruptcy, insolvency, fraudulent conveyance,
reorganization, moratorium and other laws of general applicability relating to or affecting creditors’ rights and to general
equitable principles (whether considered in a proceeding in equity or law).

 

(ii) The execution and delivery by the Purchaser
of this Agreement and the fulfillment of and compliance with the terms hereof by the Purchaser does not and shall not as of each
Closing Date conflict with or result in a breach by the Purchaser of the terms, conditions or provisions of any agreement, instrument,
order, judgment or decree to which the Purchaser is subject that would materially impact its ability to perform its obligations
hereunder..

 

C. Investment Representations.

 

(i) The Purchaser is acquiring the Private Placement
Warrants and, upon exercise of the Private Placement Warrants, the Shares issuable upon such exercise (collectively, the “Securities”),
for the Purchaser’s own account, for investment purposes only and not with a view towards, or for resale in connection with,
any public sale or distribution thereof.

 

(ii) The Purchaser is an “accredited investor”
as such term is defined in Rule 501(a)(3) of Regulation D of the Securities Act of 1933, as amended (the “Securities
Act”).

 

(iii) The Purchaser understands that the Securities
are being offered and will be sold to it in reliance on specific exemptions from the registration requirements of the United States
federal and state securities laws and that the Company is relying upon the truth and accuracy of, and the Purchaser’s compliance
with, the representations and warranties of the Purchaser set forth herein in order to determine the availability of such exemptions
and the eligibility of the Purchaser to acquire such Securities.

 

(iv) The Purchaser did not enter into this Agreement
as a result of any general solicitation or general advertising within the meaning of Rule 502(c) under the Securities Act.

 

(v) The Purchaser has been furnished with all
materials relating to the business, finances and operations of the Company and materials relating to the offer and sale of the
Securities which have been requested by the Purchaser. The Purchaser has been afforded the opportunity to ask questions of the
executive officers and directors of the Company. The Purchaser understands that its investment in the Securities involves a high
degree of risk and it has sought such accounting, legal and tax advice as it has considered necessary to make an informed investment
decision with respect to the acquisition of the Securities.

 

     

     

    

 

(vi) The Purchaser understands that no United
States federal or state agency or any other government or governmental agency has passed on or made any recommendation or endorsement
of the Securities or the fairness or suitability of the investment in the Securities by the Purchaser nor have such authorities
passed upon or endorsed the merits of the offering of the Securities.

 

(vii) The Purchaser understands that: (a) the
Securities have not been and are not being registered under the Securities Act or any state securities laws, and may not be offered
for sale, sold, assigned or transferred unless (1) subsequently registered thereunder or (2) sold in reliance on an exemption
therefrom; and (b) except as specifically set forth in the Registration Rights Agreement, neither the Company nor any other
person is under any obligation to register the Securities under the Securities Act or any state securities laws or to comply with
the terms and conditions of any exemption thereunder. While such Purchaser understands that Rule 144 under the Securities Act is
not available for the resale of securities initially issued by shell companies (other than business combination related shell companies)
or issuers that have been at any time previously a shell company, such Purchaser understands that Rule 144 includes an exception
to this prohibition if the following conditions are met: (i) the issuer of the securities that was formerly a shell company has
ceased to be a shell company; (ii) the issuer of the securities is subject to the reporting requirements of Section 13 or 15(d)
of the Securities Exchange Act of 1934, as amended (the “Exchange Act”); (iii) the issuer of the securities
has filed all Exchange Act reports and material required to be filed, as applicable, during the preceding 12 months (or such shorter
period that the issuer was required to file such reports and materials), other than Form 8-K reports; and (iv) at least one year
has elapsed from the time that the issuer filed current Form 10 type information with the SEC reflecting its status as an entity
that is not a shell company.

 

(viii) The Purchaser has such knowledge and
experience in financial and business matters, knowledge of the high degree of risk associated with investments in the securities
of companies in the development stage such as the Company, is capable of evaluating the merits and risks of an investment in the
Securities and is able to bear the economic risk of an investment in the Securities in the amount contemplated hereunder for an
indefinite period of time. The Purchaser has adequate means of providing for its current financial needs and contingencies and
will have no current or anticipated future needs for liquidity which would be jeopardized by the investment in the Securities.
The Purchaser can afford a complete loss of its investment in the Securities.

each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if
