and Onyx Acquisition Sponsor Co. LLC, a Cayman Islands 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 Class A ordinary
share of the Company, par value $0.0001 per share (each, a “Share”), and one-half of one redeemable warrant,

WHEREAS, the Purchaser has agreed to purchase an
aggregate of 9,300,000 warrants (plus up to 600,000 additional redeemable warrants if the underwriters in the Public Offering exercise
their option to purchase additional units 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, at a price of $1.00 per warrant, subject
to adjustment.


 


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:

the Purchaser and the Company (each such date, an “Option Closing Date”, and each Option Closing Date (if any)
and the IPO Closing Date, a “Closing Date”), the Company shall issue and sell to the Purchaser, and the Purchaser
shall purchase from the Company, up to 600,000 Private Placement Warrants (or, to the extent the option to purchase additional units is
not exercised in full, a lesser number of Private Placement Warrants in proportion to the portion of the option that is exercised) at
a price of $1.00 per warrant for an aggregate purchase price of up to $600,000 (the “Option Purchase Price”).
The Purchaser shall pay the Option Purchase Price in accordance with the Company’s wire instruction by wire transfer of immediately
available funds to the Trust Account, at least one (1) business day prior to any Option Closing Date. On each Option Closing Date (if

such delivery in book-entry form.

(ii) At the time of, or prior to, the IPO Closing
Date, the Company and the Purchaser shall enter into a registration and shareholder rights agreement (the “Registration and
Shareholder 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.

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


 


A. Incorporation and Corporate Power. The
Company is an exempted company duly incorporated, validly existing and in good standing under the laws of the Cayman Islands and is qualified

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,

(whether considered in a proceeding in equity or law).

Date (a) conflict with or result in a breach by the Purchaser of the terms, conditions or provisions of, (b) constitute a default under,

rule or regulation to which the Purchaser is subject, or any agreement, instrument, order, judgment or decree to which the Purchaser is
subject, except for any filings required after the date hereof under federal or state securities laws.


 


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 its 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, and the 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.


 






    4


     


    

 


(iv) The Purchaser did not decide to enter into
this Agreement as a result of any general solicitation or general advertising within the meaning of Rule 502(c) of Regulation D 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 and Shareholder 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. In this regard, the Purchaser understands that the SEC has taken the position that promoters or affiliates
of a blank check company and their transferees, both before and after an initial business combination, are deemed to be “underwriters”
under the Securities Act when reselling the securities of a blank check company. Based on that position, Rule 144 adopted pursuant to
the Securities Act would not be available for resale transactions of the Securities despite technical compliance with the requirements
of such Rule, and the Securities can be resold only through a registered offering or in reliance upon another exemption from the registration
requirements of the Securities Act.


 


(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 investments
in the Securities.


 


(ix) The Purchaser understands that the Private
Placement Warrants shall bear the legend substantially in the form set forth in the Warrant Agreement.
