FORM OF PRIVATE PLACEMENT AGREEMENT


 


THIS PRIVATE PLACEMENT AGREEMENT,

into by and between Signal Hill Acquisition Corp., a Delaware corporation (the “Company”) and Signal Hill

WHEREAS, the Company consummated
an initial public offering of the Company’s units (the “Units”, and the offering 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-half of one warrant, each whole warrant exercisable to purchase one Share (“Warrant”), on February 15,
2022, as set forth in the Company’s registration statement on Form S-1, filed with the Securities and Exchange Commission (the
 “SEC”), File Number 333-262042 (the “Registration Statement”), under the Securities Act of 1933,
as amended (the “Securities Act”);


 


WHEREAS, the Sponsor and certain
holders of the Company’s Class B common stock, par value $0.0001 per share (collectively, the “Purchaser”)
have agreed to purchase an aggregate of 6,000,000 redeemable warrants (and have the option to purchase up to an additional 600,000 warrants
if the over-allotment option in connection with the IPO is exercised in full) (the “Private Placement Warrants”) at
a price of $1.00 per Private Placement Warrant, with each Private Placement Warrant being at a price of $11.50 per Share;


 


WHEREAS, in the event the
underwriters of the IPO exercise their over-allotment option and the Purchaser elects not to purchase the up to 600,000 additional Private
Placement Warrants in connection therewith, B. Riley Securities, Inc. (“BR”) has agreed to purchase such Private
Placement Warrants at a price of $1.00 Private Placement Warrant;


 


WHEREAS, on February 15,
2022, the Purchaser purchased 5,000,000 Private Placement Warrants at a price of $1.00 per Private Placement Warrant, with each Private
Placement Warrant being at a price of $11.50 per Share; and


 


WHEREAS, the Sponsor is committed
to purchasing the balance of the 1,000,000 Private Placement Warrants no later than February 28, 2022.


 


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:


 


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 Placement Warrants.


 


(i)            As
of the date hereof (the “Closing Date”), the Company shall issue and sell to the Purchaser, and the Purchaser
shall purchase from the Company, an aggregate of 1,000,000 Private Placement Warrants at a price of $1.00 per warrant for an aggregate
purchase price of $1,000,000 (the “Purchase Price”). Purchaser shall pay the Purchase Price by wire

(ii)           In
the event that the underwriters’ over-allotment option is exercised in full or in part, the Purchaser or BR shall purchase up
to an additional 600,000 Private Placement Warrants (the “Additional Private Placement Warrants”)  in
the same proportion as the amount of the option that is so exercised, and simultaneously with such purchase of Additional Private
Placement Warrants, as payment in full for the Additional Private Placement Warrants being purchased hereunder, and at least one

$1.00 per Additional Private Placement Warrant, up to an aggregate amount of $600,000 to the trust account maintained by
Continental Stock Transfer & Trust Company, acting as trustee. The closing of the purchase and sale of the Additional
Private Placement Warrants, if applicable, shall take place simultaneously with the closing of all or any portion of the
underwriters’ over-allotment option (such closing date, together with the Closing Date, the “Closing
Dates” and each, a “Closing Date”). The closing of the purchase and sale
of the Additional Private Placement Warrants, if applicable, shall take place at the offices of Saul Ewing Arnstein & Lehr
LLP, counsel for the Company, or such other place as may be agreed upon by the parties hereto.


 






     


     


    

 


C.     Terms of
the Private Placement Warrants.


 


(i)            Each
Private Placement Warrant shall have the terms set forth in a Warrant Agreement to be entered into by the Company and Continental in connection
with the Public Offering (the “Warrant Agreement”). Such terms include the fact that the Private Placement
Warrants shall not be transferable, assignable or salable until 30 days after the completion of an initial business combination, subject
to certain exceptions set forth in the Warrant Agreement.


 


(ii)           On
or prior to the Closing Date, the Company and the Purchaser shall reaffirm their entrance or 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.


 


2.
Representations and Warranties of the Company. As a material inducement to the Purchaser to enter into this Agreement

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

Shares issuable upon exercise of the Private Placement Warrants will be duly and validly issued as fully paid and nonassessable. On

have been reserved for issuance. Upon issuance in accordance with, and payment pursuant to, the terms hereof and the Warrant
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

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 the applicable 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 the applicable 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.


 


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 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. The Private Placement Warrants will bear a legend and appropriate
 “stop transfer” instructions (or an appropriate notation if the warrants are issued in book entry form) relating to the foregoing.
The Purchaser further 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 until the one-year anniversary following consummation of an initial business
combination despite technical compliance with the requirements of such Rule.


 


(viii)        The
Purchaser has such knowledge and experience in financial and business matters, knows 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.


 


4.

Placement Warrants are subject to the fulfillment, on or before the applicable Closing Date, of each of the following conditions:

party hereto, other than assignments by the Purchaser to affiliates thereof.
