	 	Re:	Administrative Support Agreement


 


Ladies and Gentlemen:


 


This letter agreement
by and between Mudrick Capital Acquisition Corporation II (the “Company”) and Mudrick Capital Acquisition Holdings
II LLC (“Sponsor”), dated as of the date hereof, will confirm our agreement that, commencing on the effective
date (the “Effective Date”) of the Registration Statement on Form S-1 filed with the U.S. Securities and
Exchange Commission (the “Registration Statement”) for the Company’s initial public offering and continuing
until the earlier of the consummation by the Company of an initial business combination or the Company’s liquidation (in
each case as described in the Registration Statement) (such earlier date hereinafter referred to as the “Termination Date”):


 


	 	i.	Sponsor shall make available, or cause to be made available, to the Company, at 527 Madison Avenue, 6th Floor, New York, New York 10022 (or any successor location of Sponsor), certain office space, utilities and secretarial and administrative support as may be reasonably required by the Company. In exchange therefor, the Company shall pay Sponsor the sum of $10,000 per month on the Effective Date and continuing monthly thereafter until the Termination Date; and


 


	 	ii.	Sponsor hereby irrevocably waives any and all right, title, interest, causes of action and claims of any kind as a result of, or arising out of, this letter agreement (each, a “Claim”) in or to, and any and all right to seek payment of any amounts due to it out of, the trust account established for the benefit of the public stockholders of the Company and into which substantially all of the proceeds of the Company’s initial public offering will be deposited (the “Trust Account”), and hereby irrevocably waives any Claim it may have in the future, which Claim would reduce, encumber or otherwise adversely affect the Trust Account or any monies or other assets in the Trust Account, and further agrees not to seek recourse, reimbursement, payment or satisfaction of any Claim against the Trust Account or any monies or other assets in the Trust Account for any reason whatsoever.


 


This letter agreement
constitutes the entire agreement and understanding of the parties hereto in respect of its subject matter 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 amended, modified or waived as to any particular provision, except by a written instrument executed by all parties hereto.


 


No party hereto may
assign either this letter agreement or any of its rights, interests, or obligations hereunder without the prior written approval
of the other party. 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
constitutes the entire relationship of the parties hereto, and any litigation between the parties (whether grounded in contract,
tort, statute, law or equity) shall be governed by, construed in accordance with, and interpreted pursuant to the laws of the State
of New York, without giving effect to its choice of laws principles.

and Mudrick Capital Acquisition Holdings II LLC, a Delaware limited liability company (the “Purchaser”).


 


WHEREAS, the Company
intends to consummate a 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 (a “Share”), and
one-half of one redeemable warrant, each whole warrant exercisable for one Share at an exercise price of $11.50 per Share, as set
forth in the Company’s registration statement on Form S-1 related to the Public Offering (the “Registration
Statement”); and


 


WHEREAS, the Purchaser
has agreed to purchase from the Company an aggregate of 10,000,000 warrants (or up to 11,237,7500 warrants if the over-allotment
option in connection with the Public Offering is exercised in full) (the “Sponsor Warrants”), each Sponsor 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:

Company, to the trust account (the “Trust Account”) at a financial institution to be chosen by the Company,
maintained by Continental Stock Transfer & Trust Company, acting as trustee, at least one (1) business day prior
to the date of effectiveness of the Registration Statement.


 


(ii) In the event
that the over-allotment option is exercised in full or in part, Purchaser shall purchase up to an additional 1,237,500 Sponsor

that is exercised, and simultaneously with such purchase of Additional Sponsor Warrants, as payment in full for the Additional
Sponsor Warrants being purchased hereunder, and at least one (1) business day prior to the closing of all or any portion of
the over-allotment option, Purchaser shall pay $1.00 per Additional Sponsor Warrant, up to an aggregate amount of $1,237,500, by

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
Sponsor Warrants to the Purchaser, the Purchaser hereby represents and warrants to the Company (which representations and warranties
shall survive the Closing Dates) 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 the Closing Dates 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.


 


C. Investment
Representations.


 


(i) The Purchaser
is acquiring the Sponsor Warrants and, upon exercise of the Sponsor 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”), and such Purchaser has not experienced a disqualifying event
as enumerated pursuant to Rule 506(d) of Regulation D under 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.


 


Section 4. Conditions of the Purchaser’s

on or before the Closing Dates, of each of the following conditions:
