This PRIVATE PLACEMENT
UNIT PURCHASE AGREEMENT (this “Agreement”) is made as of the [●] day of [●], 2021, by and between
890 5th Avenue Partners, Inc., a Delaware corporation (the “Company”), and PA 2 Co-Investment LLC, a Delaware
limited liability company (the “Subscriber”).


 


WHEREAS, the Company
desires to sell to the Subscriber on a private placement basis (the “Sale”) an aggregate of 75,897 private placement
units (and up to 84,000 units in the aggregate if the underwriters in the IPO exercise their over-allotment option in full) (“Private
Placement Units”) of the Company for a purchase price of $10.00 per Private Placement Unit, each Private Placement Unit
comprised of one share of Class A common stock of the Company, par value $0.0001 per share (“Common Stock”),
and one-third of one redeemable warrant, each whole warrant exercisable to purchase one share of Common Stock (each whole warrant,
a “Warrant”). The shares of Common Stock underlying the Private Warrants (as defined below) are hereinafter
referred to as the “Warrant Shares.” The shares of Common Stock underlying the Private Placement Units (excluding
the Warrant Shares) are hereinafter referred to as the “Private Shares.” The Warrants underlying the Private
Placement Units are hereinafter referred to as the “Private Warrants.” The Private Placement Units, the Private
Shares, the Private Warrants and the Warrant Shares, collectively, are hereinafter referred to as the “Securities.”
Each whole Private Warrant is exercisable to purchase one share of Common Stock at an exercise price of $11.50, subject to the
adjustments as set forth in the Warrant Agreement (as defined below), during the period commencing on the later of (i) twelve (12)
months from the date of the closing of the Company’s initial public offering of units (the “IPO”) and
(ii) 30 days following the consummation of the Company’s initial business combination (the “Business Combination”),
as such term is defined in the registration statement in connection with the IPO, as amended at the time it becomes effective (the
 “Registration Statement”), filed with the Securities and Exchange Commission (“SEC”), and
expiring on the fifth anniversary of the consummation of the Business Combination (provided that so long as the Private Warrants
are held by the Subscriber, its designees or affiliates, the Subscriber, its designees or affiliates will not be permitted to exercise
such Private Warrants after the five year anniversary of the effective date of the Registration Statement); and


 


WHEREAS, the Subscriber
wishes to purchase an aggregate of 75,897 (and up to 84,000 units in the aggregate if the underwriters in the IPO exercise their
over-allotment option in full) Private Placement Units for the Purchase Price (as defined below), and the Company wishes to accept
such subscription from the Subscriber.


 


NOW, THEREFORE, in
consideration of the premises and the mutual covenants hereinafter set forth and other good and valuable consideration, the receipt
and sufficiency of which are hereby acknowledged, the Company and the Subscriber hereby agree as follows:


 


	 	1.	Agreement to Subscribe.


 


1.1          
Purchase and Issuance of the Private Placement Units.


 


(a)        Upon
the terms and subject to the conditions of this Agreement, the Subscriber hereby agrees to purchase from the Company, and the
Company hereby agrees to sell to the Subscriber, on the Initial Closing Date (as defined below) 75,897 Private Placement Units
in consideration of the payment of the Purchase Price. On the Initial Closing Date, the Company shall, at its option, deliver
to the Subscriber the certificates representing the Securities purchased or effect such delivery in book-entry form.


 


(a)       On
the date of the consummation of the closing of the over-allotment option, if any, in connection with the IPO or on such earlier
time and date as may be mutually agreed by the Subscriber and the Company (an “Over-allotment Closing Date,”
and each Over-allotment Closing Date (if any) and the Initial Closing Date, a “Closing Date”), the Company
shall issue and sell to the Subscriber, and the Subscriber shall purchase from the Company, up to 8,103 additional Private Placement
Units (or, to the extent the over-allotment option is not exercised in full, a lesser number of Private Placement Units in proportion
to the amount of the over-allotment option that is then exercised) at a price of $10.00 per Private Placement Unit for an aggregate
purchase price of up to $81,030 (if the over-allotment option is exercised in full) (such amount, the “Over-allotment
Purchase Price”). The Subscriber shall pay the Over-allotment Purchase Price by wire transfer of immediately available
funds or by such other method as may be reasonably acceptable to the 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 (“Continental”), on or prior to the Over-allotment Closing Date. On the Over-allotment Closing Date,
upon the payment by the Subscriber of the Over-allotment Purchase Price, the Company shall, at its option, deliver a certificate
evidencing the Private Placement Units purchased by the Subscriber on such date duly registered in the Subscriber’s name
to the Subscriber, or effect such delivery in book-entry form.


 






     


     


    

 


1.2           Purchase Price. As payment in full for the Private Placement Units being purchased under this Agreement at the Initial Closing
(as defined below), the Subscriber shall pay $758,970 (the “Purchase Price”) by wire transfer of immediately
available funds or by such other method as may be reasonably acceptable to the Company, to the Trust Account at a financial institution
to be chosen by the Company, maintained by Continental, on or prior to the Initial Closing Date.


 


1.3           Closing. The closing of the purchase and sale of the Private Placement Units (the “Initial Closing Date” and
the Initial Closing and each other closing, a “Closing”) shall take place on the date of the closing of the
IPO. Each Closing shall take place at the offices of the Company, or remotely via electronic exchange or at such other place or
method as may be agreed upon by the parties hereto.

		d.	No litigation, statute, rule, regulation, executive order, decree, ruling or injunction shall have
been enacted, entered, promulgated or endorsed by or in any court or governmental authority of competent jurisdiction or any self-regulatory

is terminated for any reason.


 


	 	2.	Representations and Warranties of the Subscriber.


 


Subscriber represents
and warrants to the Company that:


 


2.1           No Government Recommendation or Approval. Subscriber understands that no federal or state agency has passed upon or made any recommendation
or endorsement of the Company or the Sale of the Securities.


 


2.2           Accredited Investor. Subscriber represents that it is an “accredited investor” as such term is defined in Rule 501(a)
of Regulation D under the Securities Act of 1933, as amended (the “Securities Act”), and acknowledges that the
Sale is being made in reliance, among other things, on a private placement exemption to “accredited investors” under
the Securities Act and similar exemptions under state law.


 


2.3           Intent. Subscriber is purchasing the Securities solely for investment purposes, for Subscriber’s own account (and/or for
the account or benefit of its members or affiliates, as permitted, pursuant to the terms of an agreement (the “Insider
Letter”) to be entered into with respect to the Securities between, among others, Subscriber and the Company, as described
in the Registration Statement), and not with a view to the distribution thereof and Subscriber has no present arrangement to sell
the Securities to or through any person or entity except as may be permitted hereunder. The Subscriber shall not engage in hedging
transactions with regard to the Securities unless in compliance with the Securities Act.


 


2.4           Restrictions on Transfer. Subscriber acknowledges and understands the Private Placement Units are being offered in a transaction
not involving a public offering in the United States within the meaning of the Securities Act. The Securities have not been registered
under the Securities Act and, if in the future Subscriber decides to offer, resell, pledge or otherwise transfer the Securities,
such Securities may be offered, resold, pledged or otherwise transferred only pursuant to (i) an effective registration statement
filed under the Securities Act, (ii) an exemption from registration under Rule 144 promulgated under the Securities Act, if available,
or (iii) any other available exemption from the registration requirements of the Securities Act, and in each case in accordance
with any applicable securities laws of any state or any other jurisdiction. Notwithstanding the foregoing, Subscriber acknowledges
and understands the Securities are subject to transfer restrictions as described herein and in the Insider Letter. Subscriber agrees
that if any transfer of its Securities or any interest therein is proposed to be made, as a condition precedent to any such transfer,
Subscriber may be required to deliver to the Company an opinion of counsel satisfactory to the Company with respect to such transfer.
Absent registration or another available exemption from registration, Subscriber agrees it will not resell the Securities (unless
otherwise permitted pursuant to the terms hereof). Subscriber further acknowledges that because the Company is a shell company,
Rule 144 may not be available to Subscriber for the resale of the Securities until the one year anniversary following consummation
of the Business Combination of the Company, despite technical compliance with the requirements of Rule 144 and the release or waiver
of any contractual transfer restrictions.


 






    3


     


    

 


2.5           Sophisticated Investor.





 


(a)        Subscriber is sophisticated in financial matters and is able to evaluate the risks and benefits of the investment in the Securities.


 


(b)        Subscriber
is aware that an investment in the Securities is highly speculative and subject to substantial risks because, among other things,
the Securities are subject to transfer restrictions and have not been registered under the Securities Act and therefore cannot
be sold unless subsequently registered under the Securities Act or an exemption from such registration is available. Subscriber
is able to bear the economic risk of its investment in the Securities for an indefinite period of time.


 


2.6           Organization and Authority. Subscriber is duly organized, validly existing and in good standing under the laws of its state of
incorporation or formation and it possesses all requisite power and authority necessary to carry out the transactions contemplated
by this Agreement.


 


2.7           Authority. This Agreement has been validly authorized, executed and delivered by Subscriber and is a valid and binding agreement
enforceable in accordance with its terms, subject to the general principles of equity and to bankruptcy or other laws affecting
the enforcement of creditors’ rights generally.


 


2.8           No Conflicts. The execution, delivery and performance of this Agreement and the consummation by Subscriber of the transactions
contemplated hereby do not violate, conflict with or constitute a default under (i) Subscriber’s charter documents, (ii)
any agreement or instrument to which Subscriber is a party or (iii) any law, statute, rule or regulation to which Subscriber is
subject, or any agreement, order, judgment or decree to which Subscriber is subject.


 


2.9           No Legal Advice from Company. Subscriber acknowledges it has had the opportunity to review this Agreement and the transactions
contemplated by this Agreement and the other agreements entered into between the parties hereto with Subscriber’s own legal
counsel and investment and tax advisors. Except for any statements or representations of the Company made in this Agreement and
the other agreements entered into between the parties hereto, Subscriber is relying solely on such counsel and advisors and not
on any statements or representations of the Company or any of its representatives or agents for legal, tax or investment advice
with respect to this investment, the transactions contemplated by this Agreement or the securities laws of any jurisdiction.


 


2.10         Reliance on Representations and Warranties. The Subscriber understands the Private Placement Units are being offered and sold to
the Subscriber in reliance on exemptions from the registration requirements under the Securities Act, and analogous provisions
in the laws and regulations of various states, and that the Company is relying upon the truth and accuracy of the representations,
warranties, agreements, acknowledgments and understandings of the Subscriber set forth in this Agreement in order to determine
the applicability of such provisions.


 


2.11         No General Solicitation. Subscriber is not subscribing for the Private Placement Units as a result of or subsequent to any general
solicitation or general advertising, including but not limited to any advertisement, article, notice or other communication published
in any newspaper, magazine, or similar media or broadcast over television or radio, or presented at any seminar or meeting or in
the Registration Statement.


 


2.12         Legend. Subscriber acknowledges and agrees that each of the Private Placement Units and the shares of Common Stock included in
the Private Placement Units shall bear a restrictive legend substantially in the form set forth in Section 4.1 below, the Private
Warrants shall bear the legend substantially in the form set forth in the Warrant Agreement, and that the Securities will be subject
to appropriate “stop transfer restrictions.”

of this Agreement by the Company and the consummation by it of the transactions contemplated hereby have been duly authorized by

in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, fraudulent conveyance,

remedies or by equitable principles of general application and except as enforcement of rights to indemnity and contribution may
be limited by federal and state securities laws or principles of public policy.

with, or constitute a default under any agreement or instrument to which the Company is a party or (iii) any law statute, rule

dealer participating in the IPO and the bona fide officers or partners of any Subscriber and any such participating underwriter
or selected dealer. Additionally, the Private Placement Units and their component parts and the related registration rights will
not be the subject of any hedging, short sale, derivative, put or call transaction that would result in the economic disposition

in the Warrant Agreement, (iii) the Private Warrants may not be exercised after the five year anniversary of the effective date
of the Registration Statement pursuant to FINRA Rule 5110(g)(8) and (iv) the Private Placement Units and component parts are being
purchased pursuant to an exemption from the registration requirements of the Securities Act and will become freely tradable only
