PRIVATE PLACEMENT UNITS PURCHASE AGREEMENT


 


This PRIVATE PLACEMENT
UNITS PURCHASE AGREEMENT (this “Agreement”) is made as of the March 16, 2021, by and between Athena Technology
Acquisition Corp., a Delaware corporation (the “Company”), and Athena Technology Sponsor LLC, a Delaware
limited liability company (the “Subscriber”).


 


WHEREAS, the Company
desires to sell to the Subscriber on a private placement basis (the “Offering”) an aggregate of 700,000 units
(the “Units”) of the Company, each 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 warrant, each whole warrant exercisable to purchase
one share of Common Stock (“Warrant”), for a purchase price of $10.00 per Unit. The shares of Common Stock underlying
the Warrants are hereinafter referred to as the “Warrant Shares”.  The shares of Common Stock underlying
the Units (excluding the Warrant Shares) are hereinafter referred to as the “Placement Shares.” The Warrants
underlying the Units are hereinafter referred to as the “Placement Warrants.”  The Units, Placement
Shares, Placement Warrants and Warrant Shares, collectively, are hereinafter referred to as the “Securities.”  Each
whole Placement Warrant is exercisable to purchase one share of Common Stock at an exercise price of $11.50 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”), and expiring on the fifth anniversary
of the consummation of the Business Combination; and


 


WHEREAS, the Subscriber
wishes to purchase 700,000 Units, and the Company wishes to accept such subscription from 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 Subscriber hereby agree as follows:


 


1.
Agreement to Subscribe

 


	 	1.1.	Purchase and Issuance of the Units.  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 Closing Date (as defined below) the Units in consideration of the payment of the Purchase Price (as defined below). On the 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.  


  


	 	1.2.	Purchase Price. As payment in full for the Units being purchased under this Agreement, the Subscriber shall pay $7,000,000 (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 (the “Trust Account”) at a financial institution to be chosen by the Company, maintained by Continental Stock Transfer & Trust Company, acting as trustee (“Continental”), one (1) business day prior to the date of effectiveness of the Registration Statement.


 


1.3.  Closing.
The closing of the purchase and sale of the Units shall take place simultaneously with the closing of the IPO (the “Closing
Date”). The closing of the purchase and sale of the Units shall take place at the offices of Ellenoff Grossman &
Schole LLP, 1345 Avenue of the Americas, 11th Floor, New York, New York, 10105, or such other place as may be agreed
upon by the parties hereto.


 


1.4 Termination.
This Agreement and each of the obligations of the undersigned shall be null and void and without effect if a Closing does not occur
prior to September 30, 2021.


  






     


     


    

 


2. Representations and Warranties
of 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 Offering 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 contemplated
hereby 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 under the Insider Letter.  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 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 (A) pursuant to an effective registration statement
filed under the Securities Act, (B) pursuant to an exemption from registration under Rule 144 promulgated under the Securities
Act, if available, or (C) pursuant to 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 in Section
8 hereof. 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 Insider Letter, as described in the Registration
Statement).  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 initial Business Combination
of the Company, despite technical compliance with the requirements of Rule 144 and the release or waiver of any contractual transfer
restrictions.


  


2.5.  Sophisticated
Investor.


 


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


 


(ii) 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.    Independent
Investigation.  Subscriber, in making the decision to purchase the Units, has relied upon an independent investigation
of the Company and has not relied upon any information or representations made by any third parties or upon any oral or written
representations or assurances from the Company, its officers, directors or employees or any other representatives or agents of
the Company, other than as set forth in this Agreement. Subscriber is familiar with the business, operations and financial condition
of the Company and has had an opportunity to ask questions of, and receive answers from the Company’s officers and directors
concerning the Company and the terms and conditions of the offering of the Units and has had full access to such other information
concerning the Company as Subscriber has requested. Subscriber confirms that all documents that it has requested have been made
available and that Subscriber has been supplied with all of the additional information concerning this investment which Subscriber
has requested.


 






    2


     


    

 


2.7    Organization
and Authority.  Subscriber is duly organized, validly existing and in good standing under the laws of the State of Delaware
and it possesses all requisite power and authority necessary to carry out the transactions contemplated by this Agreement.


 


2.8.   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.


  


2.9.    
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.


 


2.10.  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.


 


2.11.  Reliance
on Representations and Warranties.  Subscriber understands the Units are being offered and sold to 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 Subscriber set forth in this Agreement in order to determine the applicability of such provisions.


 


2.12.  No General
Solicitation.  Subscriber is not subscribing for the 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 a registration statement
with respect to the IPO filed with the Securities and Exchange Commission (“SEC”).


 


2.13.  Legend.  Subscriber
acknowledges and agrees the certificates evidencing each of the Securities shall bear a restrictive legend (the “Legend”),
in form and substance substantially as set forth in Section 4 hereof.
