Item 1.01 Entry into a Material Definitive Agreement.

On July 7, 2021, Athena Technology Acquisition
Corp., a Delaware corporation (“Athena”), announced that it executed a Business Combination Agreement, dated as of
July 6, 2021, with Heliogen, Inc., a Delaware corporation (“Heliogen”), and HelioMax Merger Sub, Inc., a Delaware
corporation (“HelioMax Merger Sub”) (such business combination agreement, the “BCA,” and such business
combination, the “Business Combination”). Capitalized terms used in this Current Report on Form 8-K (this “Current
Report
”) but not otherwise defined herein have the meanings given to them in the BCA.

This Current Report on Form 8-K provides a summary of the BCA and certain
other agreements entered into (and certain agreements to be entered into) in connection with the Business Combination. The descriptions
of these agreements do not purport to be complete and are qualified in their entirety by the terms and conditions of such agreements or
the forms thereof, as applicable, copies of which are filed as Exhibits 2.1, 10.1, 10.2 and 10.3 hereto and are incorporated by reference
herein.

 

Business Combination Agreement

The below descriptions of the BCA and the transactions contemplated
thereby are not complete and are subject to, and qualified in their entirety by reference to, the actual agreement, a copy of which is
filed with this Current Report on Form 8-K as Exhibit 2.1, and the terms of which are incorporated herein by reference. The BCA has been attached to provide investors
with information regarding its terms. It is not intended to provide any other factual information about Athena, Heliogen or HelioMax Merger
Sub. In particular, the assertions embodied in the representations and warranties in the BCA were made as of the date of the BCA or other
specified date, were made for purposes of the contract among the respective parties and are subject to important qualifications and limitations
agreed to by the parties in connection with negotiating the BCA, may be subject to a contractual standard of materiality different from
what might be viewed as material to investors, or may have been used for the purpose of allocating risk between the parties. Accordingly,
the representations and warranties in the BCA are not necessarily characterizations of the actual state of facts about Heliogen or HelioMax
Merger Sub at the time they were made or otherwise and should only be read in conjunction with the other information that Athena makes
publicly available in reports, statements and other documents filed with the Securities and Exchange Commission (“SEC”).
In addition, the representations, warranties, covenants and agreements and other terms of the BCA may be subject to subsequent waiver
or modification. Moreover, information concerning the subject matter of the representations and warranties and other terms may change
after the date of the BCA, which subsequent information may or may not be fully reflected in Athena’s public disclosures.

The BCA

Pursuant to the terms of the BCA, Athena
will acquire Heliogen through the statutory merger of HelioMax Merger Sub with and into Heliogen, with Heliogen surviving the merger
as a wholly owned subsidiary of Athena (the “Merger”). At the effective time of the Merger, each share of
Heliogen common stock will be canceled and converted into the right to receive a number of shares of Class A Common Stock, par value
$0.0001 per share, of Athena (the “Athena Common Stock”) equal to the Exchange Ratio. The Exchange Ratio will be
equal to the Aggregate Merger Consideration divided by the sum of the aggregate number of shares of Heliogen common stock (including
shares of Company Restricted Stock (as defined in the BCA)) that are issued and outstanding immediately prior to the effective time
of the Merger (and, for the avoidance of doubt, following the Company SAFE Conversion, the Company Warrant Conversion and the
Company Preferred Conversion (all as defined in the BCA)) and the aggregate number of shares of Heliogen common stock issuable upon
the full exercise, settlement, exchange or conversion of Heliogen options and Heliogen restricted stock unit awards to purchase
Heliogen common stock outstanding immediately prior to the effective time of the Merger. The Aggregate Merger Consideration shall be
approximately 185,000,000 shares of Athena Common Stock (or approximately $1,850,000,000 in shares of Athena Common Stock), subject
to certain adjustments. Adjustments to the Aggregate Merger Consideration will be made for the Aggregate Company Option Exercise
Price, the amount of Company Closing Debt and the amount of Company Closing Cash.

Representations and Warranties

The BCA contains customary representations and warranties of the parties
thereto with respect to, among other things, (i) entity organization, formation and authority, (ii) capital structure, (iii) authorization
to enter into such agreements, (iv) no conflicts and required filings and consents (v) licenses and permits, (vi) information privacy
and security compliance, (vii) financial statements, (viii) absence of changes, (ix) litigation, (x) employee matters, (xi) real property,
(xii) intellectual property, (xiii) taxes, (xiv) environmental matters, (xv) material contracts, (xvi) international trade laws, (xvii)
insurance, (xviii) transactions with affiliates and (xix) brokers.

Covenants

The BCA includes customary covenants of the parties with respect to
the operation of their respective businesses prior to the consummation of the Business Combination, as applicable, and efforts to satisfy
the conditions to consummation of the Business Combination. The BCA also contains additional covenants of the parties, including, among
others, covenants providing for the parties to use their reasonable best efforts to obtain all permits, consents, approvals, authorizations,
qualifications and orders of Governmental Authorities and parties to contracts to fulfill the conditions therein, as set forth in the
BCA, and for the preparation and filing of a registration statement on Form S-4 relating to the Business Combination and containing a
proxy statement of Athena.

Incentive Plan

In connection with the Business Combination, Athena will adopt, subject
to the approval of the stockholders of Athena, an equity incentive award plan for Athena with an initial award pool of Athena Common Stock
equal to five percent (5%) of the aggregate number of shares of Athena Common Stock and securities convertible into or exercisable for
shares of Athena Common Stock outstanding as of immediately after the Closing (rounded up to the nearest whole share), which plan shall
include an “evergreen” provision pursuant to which such award pool will automatically increase for a period of ten years,
commencing on January 1, 2022 and ending on (and including) January 1, 2031, by an amount equal of up four percent (4%) of the shares
of Athena Common Stock outstanding on December 31 of the preceding year.

Stock Purchase Plan

 

In connection with the Business Combination, Athena will adopt, subject
to the approval of the stockholders of Athena, an employee stock purchase plan for Athena with an initial award pool of Athena Common
Stock equal to two percent (2%) of the aggregate number of shares of Athena Common Stock and securities convertible into or exercisable
for shares of Athena Common Stock outstanding as of immediately after the Closing (rounded up to the nearest whole share), which plan
shall include an “evergreen” provision pursuant to which such award pool will automatically increase for a period of ten years,
commencing on January 1, 2022 and ending on (and including) January 1, 2031, by an amount equal to one percent (1%) of the shares of Athena
Common Stock outstanding on December 31 of the preceding year.

no event later than three Business Days, after the satisfaction or, if permissible, waiver of the conditions set forth in the BCA.

post-closing board of directors of Athena, and (vii) upon the closing, and after giving effect to the Redemption Rights, Athena shall

Rights and Lock-Up Agreement shall have delivered to Athena copies of the Registration Rights and Lock-Up Agreement duly executed by such

Forward-Looking Statements

This Current Report on Form 8-K contains forward-looking statements
within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as
amended, including statements regarding Athena or Athena’s management team’s expectations, hopes, beliefs, intentions, plans,
prospects or strategies regarding the future, including possible business combinations. Any statements contained herein that are not statements
of historical fact may be deemed to be forward-looking statements. In addition, any statements that refer to projections, forecasts or
other characterizations of future events or circumstances, including any underlying assumptions, are forward-looking statements. The words
“anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,”
“intends,” “may,” “might,” “plan,” “possible,” “potential,” “predict,”
“project,” “should,” “would” and similar expressions may identify forward-looking statements, but
the absence of these words does not mean that a statement is not forward-looking. The forward-looking statements contained in this Current
Report on Form 8-K are based on Athena’s current expectations and beliefs of the management of Athena and/or Heliogen in light of
their respective experience and their perception of historical trends, current conditions and expected future developments and their potential
effects on Heliogen and Athena as well as other factors they believe are appropriate in the circumstances. There can be no assurance that
future developments affecting Heliogen or Athena will be those that we have anticipated. These forward-looking statements involve a number
of risks, uncertainties (some of which are beyond the control of the parties) or other assumptions that may cause actual results or performance
to be materially different from those expressed or implied by these forward-looking statements, including that the Athena stockholders
will approve the transaction, the ability of the post-combination company to meet the NYSE listing standards, and that Heliogen will have
sufficient capital upon the approval of the transactions to operate as anticipated. Should one or more of these risks or uncertainties
materialize, or should any of Athena’s assumptions prove incorrect, actual results may vary in material respects from those projected
in these forward-looking statements. Additional factors that could cause actual results to differ are discussed under the heading “Risk
Factors” and in other sections of Athena’s filings with the SEC, and in Athena’s current and periodic reports filed
or furnished from time to time with the SEC. All forward-looking statements in this Current Report on Form 8-K are made as of the date
hereof, based on information available to Athena and/or Heliogen as of the date hereof, and Athena and/or Heliogen assumes no obligation
to update any forward-looking statement, whether as a result of new information, future events or otherwise, except as may be required
under applicable securities laws.

No Offer or Solicitation

This Current Report on Form 8-K shall not constitute a solicitation
of a proxy, consent or authorization with respect to any securities or in respect of the Business Combination. This Current Report on
Form 8-K shall also not constitute an offer to sell or the solicitation of an offer to buy any securities, nor shall there be any sale
of securities in any states or jurisdictions in which such offer, solicitation or sale would be unlawful prior to registration or qualification
under the securities laws of any such jurisdiction.

share of Company Common Stock issued and outstanding immediately prior to the Effective Time (including each share of Company Restricted

that would otherwise be issuable to such person following such aggregation shall be rounded up to a whole share of Athena Common Stock.

Section 3.3
Exchange of Certificates.

(a) Exchange
Agent
. On or prior to the Closing Date, Athena shall deposit, or shall cause to be deposited, with a bank or trust company that shall
be designated by Athena and is reasonably satisfactory to the Company (the “Exchange Agent”), for the benefit
of the holders of Company Common Stock, for exchange in accordance with this Article III, the number of shares of Athena Common
Stock sufficient to deliver the aggregate Per Share Merger Consideration payable pursuant to this Agreement (such shares of Athena Common
Stock, and any dividends or distributions with respect thereto (pursuant to Section 3.3(c)), being hereinafter referred to as the
Exchange Fund”). Athena shall cause the Exchange Agent pursuant to irrevocable instructions, to pay the Per
Share Merger Consideration out of the Exchange Fund in accordance with this Agreement. Except as contemplated by Section 3.3(c),
the Exchange Fund shall not be used for any other purpose.

(b) Exchange
Procedures
. As promptly as practicable after the date hereof, Athena shall use its reasonable best efforts to cause the Exchange Agent
to mail to each holder of Company Common Stock entitled to receive the Per Share Merger Consideration pursuant to Section 3.1:
a letter of transmittal, which shall be in a form reasonably acceptable to Athena and the Company (the “Letter of Transmittal”)
and shall specify (i) that delivery shall be effected, and risk of loss and title to the certificates evidencing such shares of Company
Common Stock (the “Certificates”) shall pass, only upon proper delivery of the Certificates to the Exchange
Agent or confirmation of cancellation of such Certificates from the Company’s transfer agent, Continental Stock Transfer &
Trust Company (each, a “Transfer Agent Cancellation”) or if such Certificates are held by the Company in electronic
format, upon confirmation of cancellation of such Certificates by the Company; and (ii) instructions for use in effecting the surrender
of the Certificates pursuant to the Letter of Transmittal. Within two (2) Business Days (but in no event prior to the Effective Time)
after the surrender to the Exchange Agent of all Certificates held by such holder for cancellation (or a Transfer Agent Cancellation),
together with a Letter of Transmittal, duly completed and validly executed in accordance with the instructions thereto and such other
documents as may be reasonably required pursuant to such instructions, the holder of such Certificates shall be entitled to receive in
exchange therefore, and Athena shall cause the Exchange Agent to deliver, the Per Share Merger Consideration in accordance with the provisions
of Section 3.1, and the Certificate so surrendered shall forthwith be cancelled. Until surrendered as contemplated by this Section
3.3
, each Certificate entitled to receive the Per Share Merger Consideration in accordance with Section 3.2(a)(i) shall be
deemed at all times after the Effective Time to represent only the right to receive upon such surrender the Per Share Merger Consideration
that such holder is entitled to receive in accordance with the provisions of Section 3.2(a)(i).

(c) Distributions
with Respect to Unexchanged Shares of Athena Common Stock
. No dividends or other distributions declared or made after the Effective
Time with respect to the Athena Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered
Certificate with respect to the shares of Athena Common Stock represented thereby until the holder of such Certificate shall surrender
such Certificate in accordance with Section 3.3(b). Subject to the effect of escheat, tax or other applicable Laws, following surrender
of any such Certificate, Athena shall pay or cause to be paid to the holder of the certificates representing shares of Athena Common Stock
issued in exchange therefore, without interest, (i) promptly, but in any event within five (5) Business Days of such surrender, the
amount of dividends or other distributions with a record date after the Effective Time and theretofore paid with respect to such shares
of Athena Common Stock, and (ii) at the appropriate payment date, the amount of dividends or other distributions, with a record date after
the Effective Time but prior to surrender and a payment date occurring after surrender, payable with respect to such shares of Athena
Common Stock.

(d) No
Further Rights in Company Common Stock
. The Per Share Merger Consideration payable upon conversion of the Company Common Stock in
accordance with the terms hereof shall be deemed to have been paid and issued in full satisfaction of all rights pertaining to such Company
Common Stock.

(e) Adjustments
to Per Share Consideration
. The Per Share Merger Consideration shall be adjusted to reflect appropriately the effect of any stock
split, reverse stock split, stock dividend, reorganization, recapitalization, reclassification, combination, exchange of shares or other
like change with respect to Athena Common Stock occurring on or after the date hereof and prior to the Effective Time.

(f) Termination
of Exchange Fund
. Any portion of the Exchange Fund that remains undistributed to the holders of Company Common Stock for one (1) year
after the Effective Time shall be delivered to Athena, upon demand, and any holders of Company Common Stock who have not theretofore complied
with this Section 3.3 shall thereafter look only to Athena for the Per Share Merger Consideration. Any portion of the Exchange
Fund remaining unclaimed by holders of Company Common Stock as of a date which is immediately prior to such time as such amounts would
otherwise escheat to or become property of any government entity shall, to the extent permitted by applicable law, become the property
of Athena free and clear of any claims or interest of any person previously entitled thereto.

(g) No
Liability
. None of the Exchange Agent, Athena or the Surviving Corporation shall be liable to any holder of Company Common Stock for
any such Company Common Stock (or dividends or distributions with respect thereto) or cash delivered to a public official pursuant to
any abandoned property, escheat or similar Law in accordance with Section 3.3.

(h) Withholding
Rights
. Each of the Surviving Corporation and Athena shall be entitled to deduct and withhold from the consideration otherwise payable
pursuant to this Agreement to person such amounts as it is required to deduct and withhold with respect to the making of such payment
under the United States Internal Revenue Code of 1986, as amended (the “Code”) or any provision of state, local
or foreign tax law. To the extent that amounts are so withheld by the Surviving Corporation or Athena, as the case may be, and paid to
the applicable Governmental Authority, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to
the person in respect of which such deduction and withholding was made by the Surviving Corporation or Athena, as the case may be. Athena
shall use commercially reasonable efforts to provide the Company with at least five (5) Business Days prior written notice of any amounts
that it intends to withhold in connection with the payment of the consideration hereunder and will reasonably cooperate with the Company
to reduce or eliminate any applicable withholding.

(i) Lost
Certificates
. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person
claiming such Certificate to be lost, stolen or destroyed, the Exchange Agent will issue in exchange for such lost, stolen or destroyed
Certificate, the Per Share Merger Consideration that such holder is otherwise entitled to receive pursuant to, and in accordance with,
the provisions of Section 3.2(a)(i).

Section 3.4 Stock Transfer
Books
. At the Effective Time, the stock transfer books of the Company shall be closed and there shall be no further registration
of transfers of Company Common Stock thereafter on the records of the Company. From and after the Effective Time, the holders of Certificates
representing Company Common Stock outstanding immediately prior to the Effective Time shall cease to have any rights with respect to
such Company Common Stock, except as otherwise provided in this Agreement or by Law. On or after the Effective Time, any Certificates
presented to the Exchange Agent or Athena for any reason shall be converted into the Per Share Merger Consideration in accordance with
the provisions of Section 3.2(a)(i).

immediately prior to the Effective Time and that are held by stockholders of the Company who shall have neither voted in favor of the

and payment under the DGCL. Any stockholder of the Company who fails to perfect or who effectively withdraws or otherwise loses his, her

in respect of the Company Common Stock, Company Options, Company RSU Awards or Company Warrants (or, for the avoidance of doubt, the Company
Equityholders) exceed the Aggregate Merger Consideration and (y) Athena, Merger Sub and the Exchange Agent will be entitled to rely upon

and unexercised as of immediately prior to the Effective Time shall be assumed by Athena and converted into an option to purchase a number
of Athena Common Stock (such option, a “Rollover Option”) equal to the product (rounded down to the nearest

multiplied by (y) the Exchange Ratio, at an exercise price per share (rounded up to the nearest whole cent) equal to the quotient

Stock subject to such Company RSU Award immediately prior to the Effective Time, multiplied by (y) the Exchange Ratio. Each Rollover
RSU Award shall be subject to the same terms and conditions (including applicable vesting and forfeiture provisions) that applied to
the corresponding Company RSU Award immediately prior to the Effective Time, except (I) as provided above in this Section 3.8(b), or
(II) as to terms (1) rendered inoperative by reason of the transactions contemplated by this Agreement (including any anti-dilution or
other similar provisions that adjust the number of underlying shares that are subject to any such award), or (2) such other immaterial
administrative or ministerial changes as the Athena Board may determine in good faith are appropriate to effectuate the administration
of the Rollover RSU Awards.

(c) As
of immediately prior to the Effective Time, all Company Equity Plans shall terminate; provided that Rollover Options and Rollover

(d) At
or prior to the Effective Time, the parties and their respective boards of directors, as applicable, shall adopt any resolutions and

threatened. To the Company’s knowledge, the Company is not in conflict with, or in default, breach or violation of, (a) any Law
applicable to the Company or by which any property or asset of the Company is bound or affected, or (b) any Material Contract or Company

has filed all forms, reports, schedules, statements and other documents, including any exhibits thereto, required to be filed by it with
the Securities and Exchange Commission (the “SEC”) since March 19, 2021, together with any amendments, restatements
or supplements thereto (collectively, the “Athena SEC Reports”). Athena has heretofore furnished to the Company
true and correct copies of all amendments and modifications that have not been filed by Athena with the SEC to all agreements, documents
and other instruments that previously had been filed by Athena with the SEC and are currently in effect. As of their respective dates,
the Athena SEC Reports (i) complied in all material respects with the applicable requirements of the Securities Act of 1933, as amended
(the “Securities Act”), the Exchange Act and the Sarbanes-Oxley Act, and the rules and regulations promulgated
thereunder, in each case, as in effect at the time they were filed, and (ii) did not, at the time they were filed, or, if amended, as
of the date of such amendment, contain any untrue statement of a material fact or omit to state a material fact required to be stated
therein or necessary in order to make the statements made therein, in the light of the circumstances under which they were made, not
misleading. Each director and executive officer of Athena has filed with the SEC on a timely basis all documents required with respect
to their respective shares of Athena Common Stock by Section 16(a) of the Exchange Act and the rules and regulations thereunder.

(b) Except
for the misapplication of the accounting guidance related to the Athena Warrants in respect of which Athena has revised and may be required
to revise or restate the financial statements included in the Athena SEC Reports to reflect the classification of the Athena Warrants
as liabilities for accounting purposes in connection with the SEC Warrant Statement, each of the financial statements (including, in
each case, any notes thereto) contained in the Athena SEC Reports was prepared in accordance with GAAP (applied on a consistent basis)
and Regulation S-X and Regulation S-K, as applicable, throughout the periods indicated (except as may be indicated in the notes thereto
or, in the case of unaudited financial statements, as permitted by Form 10-Q of the SEC) and each fairly presents, in all material respects,
the financial position, results of operations, changes in stockholders equity and cash flows of Athena as at the respective dates thereof
and for the respective periods indicated therein, (subject, in the case of unaudited statements, to normal and recurring year-end adjustments
which have not had, and would not reasonably be expected to individually or in the aggregate be material). The Company acknowledges that
(i) the Staff of the SEC issued the SEC Warrant Statement, (ii) Athena and its independent public financial accounting firm continues
to review the SEC Warrant Statement and its implications, including on the financial statements and other information included in the
Athena’s SEC Filings, and (iii) any restatement, revision or other modification of the Athena SEC Filings in connection with such
review of the SEC Warrant Statement or any subsequent related agreements or other guidance from the Staff of the SEC shall be deemed
not material for purposes of this Agreement, including for purposes of any provision of this Section 5.7. Athena has no off-balance
sheet arrangements that are not disclosed in the Athena SEC Reports. No financial statements other than those of Athena are required
by GAAP to be included in the consolidated financial statements of Athena.

(c) Except
in respect of the SEC Warrant Statement and the revision or restatement of the financial statements included in the Athena SEC Reports
to reflect the classification of the Athena Warrants as liabilities for accounting purposes in connection therewith) and as and to the
extent set forth in the Athena SEC Reports, neither Athena nor Merger Sub has any liability or obligation of a nature (whether accrued,
absolute, contingent or otherwise) required to be reflected on a balance sheet prepared in accordance with GAAP, except for liabilities
and obligations arising in the ordinary course of Athena’s and Merger Sub’s business.

(d) Athena
is in compliance, or as of Closing, will be in compliance, in all material respects with the applicable listing and corporate governance
rules and regulations of the New York Stock Exchange.

(e) Athena
has established and maintains disclosure controls and procedures (as defined in Rule 13a-15 under the Exchange Act). Such disclosure
controls and procedures are designed to ensure that material information relating to Athena and other material information required to
be disclosed by Athena in the reports and other documents that it files or furnishes under the Exchange Act is recorded, processed, summarized
and reported within the time periods specified in the rules and forms of the SEC, and that all such material information is accumulated
and communicated to Athena’s principal executive officer and its principal financial officer as appropriate to allow timely decisions
regarding required disclosure and to make the certifications required pursuant to Sections 302 and 906 of the Sarbanes-Oxley Act. Such
disclosure controls and procedures are effective in timely alerting Athena’s principal executive officer and principal financial
officer to material information required to be included in Athena’s periodic reports required under the Exchange Act, except that
due to the reclassification of the Athena Warrants in connection with the SEC Warrant Statement a material weakness existed in Athena’s
disclosure controls and procedures and such disclosures controls and procedures were not effective, and such material weakness in Athena’s
disclosure controls and procedures may continue to exist and not be effective after the date hereof.

(f) Athena
maintains systems of internal control over financial reporting that are sufficient to provide reasonable assurance regarding the reliability
of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP, including policies

fairly reflect, in all material respects, its transactions and dispositions of assets; (ii) that transactions are recorded as necessary
to permit the preparation of financial statements in conformity with GAAP; (iii) that receipts and expenditures are being made only in
accordance with authorizations of management and its board of directors; and (iv) regarding prevention or timely detection of unauthorized
acquisition, use or disposition of its assets that could have a material effect on its financial statements. Athena has delivered to
the Company a true and complete copy of any disclosure (or, if unwritten, a summary thereof) by any representative of Athena to Athena’s
independent auditors relating to any material weaknesses in internal controls and any significant deficiencies in the design or operation
of internal controls that would adversely affect the ability of Athena to record, process, summarize and report financial data; however,
due to the improper classification of the Athena Warrants in connection with the SEC Warrant Statement there was, and may continue to
be, a material weakness in Athena’s internal control over financial reporting. Athena has no knowledge of any fraud or whistle-blower
allegations, whether or not material, that involve management or other employees or consultants who have or had a significant role in
the internal control over financial reporting of Athena. Since March 19, 2021, there have been no material changes in Athena internal
control over financial reporting, except in respect of the SEC Warrant Statement and as disclosed in Athena’s SEC Reports.

(g) There
are no outstanding loans or other extensions of credit made by Athena to any executive officer (as defined in Rule 3b-7 under the Exchange
Act) or director of Athena. Athena has not taken any action prohibited by Section 402 of the Sarbanes-Oxley Act.

(h) Neither
Athena (including any employee thereof) nor Athena’s independent auditors has identified or been made aware of (i) any significant
deficiency or material weakness in the system of internal accounting controls utilized by Athena (other than those due to the SEC Warrant
Statement), (ii) any fraud, whether or not material, that involves Athena’s management or other employees who have a role in the
preparation of financial statements or the internal accounting controls utilized by Athena or (iii) any claim or allegation regarding
any of the foregoing.

(i) As

none of the Athena SEC Reports filed on or prior to the date hereof is subject to ongoing SEC review or investigation as of the date
hereof.

Investment Management Trust Agreement, dated as of March 19, 2021, between Athena and the Trustee (the “Trust Agreement”).
The Trust Agreement has not been amended or modified and is valid and in full force and effect and is enforceable in accordance with
its terms, subject to the Remedies Exceptions. Athena has complied in all material respects with the terms of the Trust Agreement and
is not in breach thereof or default thereunder and there does not exist under the Trust Agreement any event which, with the giving of
notice or the lapse of time, would constitute such a breach or default by Athena or the Trustee. There are no separate Contracts side
letters or other understandings (whether written or unwritten, express or implied): (i) between Athena and the Trustee that would cause
the description of the Trust Agreement in the Athena SEC Reports to be inaccurate in any material respect; or (ii) to the knowledge of
Athena, that would entitle any person (other than stockholders of Athena who shall have elected to redeem their shares of Athena Common
Stock pursuant to the Athena Organizational Documents) to any portion of the proceeds in the Trust Account. Prior to the Closing, none
of the funds held in the Trust Account may be released except: (A) to pay income and franchise taxes from any interest income earned
in the Trust Account; and (B) upon the exercise of Redemption Rights in accordance with the provisions of the Athena Organizational Documents.
As of the date hereof, there are no Actions pending or, to the knowledge of Athena, threatened in writing with respect to the Trust Account.
Upon consummation of the Merger and notice thereof to the Trustee pursuant to the Trust Agreement, Athena shall cause the Trustee to,
and the Trustee shall thereupon be obligated to, release to Athena as promptly as practicable, the Trust Funds in accordance with the
Trust Agreement at which point the Trust Account shall terminate; provided, however that the liabilities and obligations of Athena due
and owing or incurred at or prior to the Effective Time shall be paid as and when due, including all amounts payable (a) to stockholders
of Athena who shall have exercised their Redemption Rights, (b) with respect to filings, applications and/or other actions taken pursuant
to this Agreement required under Law, (c) to the Trustee for fees and costs incurred in accordance with the Trust Agreement; and (d)
to third parties (e.g., professionals, printers, etc.) who have rendered services to Athena in connection with its efforts to effect
the Merger. As of the date hereof, assuming the accuracy of the representations and warranties of the Company herein and the compliance
by the Company with its respective obligations hereunder, Athena has no reason to believe that any of the conditions to the use of funds
in the Trust Account will not be satisfied or funds available in the Trust Account will not be available to Athena at the Effective Time.

Section 5.15 Employees.

Athena has no unsatisfied material liability with respect to any employee, officer or director. Athena and Merger Sub have never and

nor shall at any time hereafter, have any right, title, interest or claim of any kind in or to any monies in the Trust Account, or make
any claim against the Trust Account, in connection with or relating to this Agreement or the transactions contemplated hereby, regardless
of whether such claim arises based on contract, tort, equity or any other theory of legal liability (any and all such claims are collectively
referred to in this Section 6.3 as the “Released Claims”); provided, however, that the foregoing
waiver will not limit or prohibit the Company from pursuing a claim against the Athena, Merger Sub or any other person for legal relief
against monies or other assets of the Athena held outside of the Trust Account (including any funds that have been released from the
Trust Account and any asset that have been purchased or acquired with any such funds) or for specific performance or other equitable
relief in connection with the transaction contemplated hereby, including a claim for Athena to specifically perform its obligations under

rights of the Public Stockholders), or for fraud (the “Retained Claims”). The Company hereby irrevocably waives
any Released Claims that the Company may have against the Trust Account now or in the future as a result of, or arising out of this Agreement
or the transactions contemplated hereby and will not seek recourse against the Trust Account for any Released Claims; provided, however,
that the Company does not waive any Retained Claims. The Company agrees and acknowledges that such irrevocable waiver is material
to this Agreement and specifically relied upon by Athena and Merger Sub and their respective affiliates to induce Athena and Merger Sub
to enter into this Agreement, and the Company further intends and understands such waiver to be valid, binding and enforceable against
the Company under applicable law. In the event that the Company commences any action or proceeding against or involving the Trust Fund
in violation of the foregoing, Athena or Merger Sub shall be entitled to recover from the Company the associated reasonable legal fees
and costs in connection with any such action, in the event Athena or Merger Sub, as applicable, prevails in such action or proceeding.

of a material fact or omit to state a material fact necessary in order to make the statements made, in light of the circumstances under

will regularly provide the Company with information as to its progress addressing such guidance, and will consult with the Company in
good faith prior to taking any definitive position or action with respect thereto; provided, that the foregoing shall not in any manner
delay or prevent Athena from taking any position that the Athena Board, after consultation with its advisors, has determined is required
to comply with such guidance. If reasonably requested by the Company after consultation with Athena in good faith, Athena shall use commercially
reasonable efforts to seek an amendment of the outstanding Athena Warrants, in a form reasonably acceptable to Athena and the Company,

and other applicable accounting guidance, to enable Merger Sub, following the Closing, to account for such warrants as equity on the
financial statements of Merger Sub; provided, that the Company shall provide such request in writing at least ten (10) Business
Days prior to the date that the SEC declares the Registration Statement effective. If such amendment to the Athena Warrants is undertaken
pursuant this Section 7.2, Athena shall recommend to the holders of Athena Warrants entitled to vote thereon that the proposed
amendment be approved. For the avoidance of doubt, under no circumstances shall (i) the approval or execution of any such amendment by

party is subject to an exclusivity agreement that prohibits it from considering such inquiry or proposal, and will provide the other
party with the non-confidential material terms of such inquiry or proposal. Without limiting the foregoing, the parties agree that any

any proposed communication by such party to any Governmental Authority in connection with the Transactions. No party to this Agreement
shall agree to participate in any meeting with any Governmental Authority in respect of any filings, investigation or other inquiry unless
it consults with the other parties in advance and, to the extent permitted by such Governmental Authority, gives the other parties the
opportunity to attend and participate at such meeting. Subject to the terms of the Confidentiality Agreement, the parties will coordinate
and cooperate fully with each other in exchanging such information and providing such assistance as the other parties may reasonably
request in connection with the foregoing. Subject to the terms of the Confidentiality Agreement, the parties will provide each other
with copies of all material correspondence, filings or communications, including any documents, information and data contained therewith,
between them or any of their Representatives, on the one hand, and any Governmental Authority or members of its staff, on the other hand,
with respect to this Agreement and the Transactions contemplated hereby. No party shall take or cause to be taken any action before any
Governmental Authority that is inconsistent with or intended to delay its action on requests for a consent or the consummation of the

(c) From
the date of the announcement of this Agreement or the transactions contemplated hereby (pursuant to any applicable public communication

and the Company. Thereafter, between the date of this Agreement and the Closing Date (or the earlier termination of this Agreement in

each of Athena and the Company shall each use its reasonable best efforts to consult with each other before issuing any press release
or otherwise making any public statements with respect to this Agreement, the Merger or any of the other Transactions, and shall use
commercially reasonable efforts not issue any such press release or make any such public statement without the prior written consent
of the other party; provided, however, that the foregoing shall not prevent or prohibit Athena from making any filings or disclosures
that Athena, upon the advice of counsel, determines are required to be made under the Securities Act or Exchange Act or the rules or
regulations of the New York Stock Exchange; provided, further, that in such an event, the party making such filing or disclosure shall
use its commercially reasonable efforts to consult with the other party in advance as to its form, content and timing.

Section 7.12 Tax Matters.
Each of Athena, Merger Sub and the Company shall use their respective commercially reasonable efforts to cause the Merger to qualify,
and agree not to, and not to permit or cause any of their affiliates or subsidiaries to, take any action which to its knowledge could
reasonably be expected to prevent or impede the Merger from qualifying, as a reorganization within the meaning of Section 368(a) of the
Code. This Agreement is intended to constitute, and the parties hereto hereby adopt this Agreement as, a “plan of reorganization”
within the meaning of Treasury Regulation Sections 1.368-2(g) and 1.368-3(a). Each of Athena, Merger Sub and the Company shall report
the Merger as a reorganization within the meaning of Section 368(a) of the Code unless otherwise required pursuant to a “determination”
within the meaning of Section 1313(a) of the Code, including attaching the statement described in Treasury Regulations Section 1.368-3(a)
on or with its Tax Return for the taxable year of the Merger. Each party shall promptly notify the other party in writing if, before
the Closing Date, such party knows or has reason to believe that the Merger may not qualify for the Intended Tax Treatment (and whether
the terms of this Agreement could be reasonably amended in order to facilitate such qualification). Without limiting the generality of
the foregoing, if the Company reasonably determines on advice of its counsel that there is a material risk that the Merger will not qualify
for the Intended Tax Treatment, but would be reasonably expected to so qualify if a second-step merger of the Surviving Corporation into
a limited liability company directly and wholly owned by Athena that is disregarded as an entity for federal tax purposes were consummated,
in accordance with Delaware law, as promptly as practicable following the Merger (such second-step merger, the “Second Merger”),
then the Second Merger shall be so consummated; provided, that if such Second Merger occurs, (i) the Merger and the Second Merger shall
be treated as one integrated transaction for U.S. federal income tax purposes and (ii) references to the Company or the Surviving Corporation
(in each case, after the effective time of the Second Merger) and all other provisions of this Agreement shall be interpreted mutatis
mutandis
to take into account the change in structure of the business combination. The transactions contemplated by this agreement
shall be reported by the parties for all Tax purposes in accordance with the foregoing, unless otherwise required by a Governmental Authority
as a result of a “determination” within the meaning of Section 1313(a) of the Code. The parties shall cooperate with each
other and their respective counsel to document and support the Intended Tax Treatment, and each party shall use its reasonable best efforts
to execute and deliver to counsel of the Company, and/or Athena, as the case may be, letters of representation customary for transactions
of this type and reasonably satisfactory to counsel of the Company, or Athena, as the case may be, at such time and times as such counsel
shall reasonably request, including in connection with the filing and/or effectiveness of the Registration Statement. If an opinion with
respect to the Intended Tax Treatment is required or requested by the SEC, the Company and Athena shall use their respective reasonable
best efforts to cause each of their respective counsel to render such an opinion.

Section 7.13 Stock Exchange
Listing

such shares of Athena Common Stock and the Company shall reasonably cooperate with Athena with respect to such listing.

information and documentary material that may be requested by any Governmental Authority pursuant to any Laws that are designed to prohibit,
restrict or regulate actions having the purpose or effect of monopolization or restraint of trade, including the HSR Act (“Antitrust
Laws
”) and to take all other actions necessary, proper or advisable to cause the expiration or termination of the applicable
waiting periods or obtain required approvals, as applicable under Antitrust Laws as soon as practicable, including by requesting early
termination of the waiting period provided for under the HSR Act.

(b) Each
party shall, in connection with its efforts to obtain all requisite approvals and authorizations for the Transactions under any Antitrust
Law, use its commercially reasonable efforts to: (i) cooperate in all respects with each other party or its affiliates in connection
with any filing or submission and in connection with any investigation or other inquiry, including any proceeding initiated by a private
person; (ii) keep the other parties promptly informed of any communication received by such party or its Representatives from, or given
by such party or its Representatives to, any Governmental Authority and of any communication received or given in connection with any
proceeding by a private person, in each case regarding any of the Transactions; (iii) permit the other parties and their respective outside
counsel to review in advance any communication given by it to any Governmental Authority concerning the Transactions, consider in good
faith the views of the other in connection with any proposed written communications by such party to any Governmental Authority concerning
the Transactions, and consult with each other in advance of any meeting or conference with, any Governmental Authority or, in connection
with any proceeding by a private person, with any other person, and to the extent not prohibited by such Governmental Authority or other
person, give the other parties the opportunity to attend and participate in such meetings and conferences; (iv) in the event a party
is prohibited from participating in or attending any meetings or conferences, the other parties shall keep such party promptly and reasonably
apprised with respect thereto; and (v) use commercially reasonable efforts to cooperate in the filing of any memoranda, white papers,
filings, correspondence or other written communications explaining or defending the Transactions, articulating any regulatory or competitive
argument, and/or responding to requests or objections made by any Governmental Authority. Materials required to be provided pursuant
to this Section 7.14(b) may be restricted to outside counsel and redacted (1) to remove references concerning the valuation of
the Company, (2) as necessary to comply with contractual arrangements, and (3) as necessary to address attorney-client privilege concerns.

(c) No
party hereto shall take any action that could reasonably be expected to adversely affect or materially delay the approval of any Governmental
Authority of any required filings or applications under Antitrust Laws, including that Athena shall not, and shall cause its Affiliates
not to, acquire or agree to acquire by merging or consolidating with, or by purchasing a substantial portion of the assets of or equity
in, or by any other manner, any Person or portion thereof, or otherwise acquire or agree to acquire any assets, if such acquisition or
agreement would reasonably be expected to delay obtaining or significantly increase the risk of not obtaining, any authorizations, consents,
orders, declarations or approvals of any Governmental Authority necessary to consummate the Transactions or the expiration or termination
of any applicable waiting period. The parties hereto further covenant and agree, with respect to a threatened or pending preliminary
or permanent injunction or other order, decree or ruling or statute, rule, regulation or executive order that would adversely affect
the ability of the parties to consummate the Transactions, to use commercially reasonable efforts to prevent or lift the entry, enactment
or promulgation thereof, as the case may be.

Company shall use reasonable best efforts to deliver to Athena true and complete copies of the reviewed financial statements of the Company

Certificate of Incorporation will be terminated and Athena shall have no obligation whatsoever to dissolve and liquidate the assets of
Athena by reason of the consummation of the Merger or otherwise, and no stockholder of Athena shall be entitled to receive any amount
from the Trust Account. At least 48 hours prior to the Effective Time, Athena shall provide notice to the Trustee in accordance with
the Trust Agreement and shall deliver any other documents, opinions or notices required to be delivered to the Trustee pursuant to the
Trust Agreement and cause the Trustee prior to the Effective Time to, and the Trustee shall thereupon be obligated to, transfer all funds
held in the Trust Account to Athena (to be held as available cash on the balance sheet of Athena, and to be used for working capital
and other general corporate purposes of the business following the Closing) and thereafter shall cause the Trust Account and the Trust
Agreement to terminate.

Section 7.17 Financing.
Unless otherwise approved in writing by the Company (which approval shall not be unreasonably withheld, conditioned or delayed), and
except for any of the following actions that would not increase conditionality or impose any new obligation on the Company or Athena,
reduce the PIPE Financing Amount or the subscription amount under any Subscription Agreement or reduce or impair the rights of Athena
or the third-party beneficiary rights of the Company under any Subscription Agreement, Athena shall not permit any amendment or modification
to be made to, any waiver (in whole or in part) of, or provide consent to modify (including consent to terminate), any provision or remedy
under, or any replacements of, any of the Subscription Agreements, in each case, other than any assignment or transfer contemplated therein
or expressly permitted thereby (without any further amendment, modification or waiver to such assignment or transfer provision) or any
amendment, modification or waiver that is solely ministerial in nature or otherwise immaterial, and, in each case, that does not affect
any economic or any other material term, shall not require the prior written consent; provided, that, in the case of any such
assignment or transfer, the initial party to such Subscription Agreement remains bound by its obligations with respect thereto in the
event that the transferee or assignee, as applicable, does not comply with its obligations to consummate the purchase of shares of Athena
Common Stock contemplated thereby. Athena shall use its reasonable best efforts to (i) enforce the obligations of the PIPE Investors
under the Subscription Agreements and consummate the purchases contemplated by the Subscription Agreements on the terms and subject to
the conditions set forth in the Subscription Agreements, (ii) satisfy all conditions to the PIPE Financing set forth in the Subscription
Agreements that are within its control, and (iii) satisfy and comply with its obligations under the Subscription Agreements. The Company

and its Representatives in connection with the matters specified in this Section 7.17, including, without limitation, to satisfy
all conditions to the PIPE Financing set forth in the Subscription Agreements that are within its control. If reasonably requested by
the Company, Athena shall, to the extent it has such rights under the Subscription Agreement, waive any breach of any representation,
warranty, covenant or agreement of the Subscription Agreement by any PIPE Investor to the extent necessary to cause the satisfaction
of the conditions to closing of the PIPE Financing set forth in the Subscription Agreements and solely for the purpose of consummating
the Closing, provided that (i) any such waiver may be subject to, and conditioned upon, the Closing occurring and the substantially concurrent
funding of such PIPE Financing, (ii) subject to, and condition upon, the Closing occurring substantially concurrent funding of the PIPE
Financing, the Company also waives any such breach to the extent the Company is a third party beneficiary of the provision that was so
breached (iii) any such waiver shall be subject to the rights of the placement agent, as applicable, under such Subscription Agreement
with respect to such waiver.

Performance

(d) Severability.
If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of law, or public policy,
all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal
substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon such determination
that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith
to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in
order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.

all prior agreements and undertakings, both written and oral, among the parties, or any of them, with respect to the subject matter hereof.

by any party without the prior express written consent of the other parties hereto, and any such assignment without such consent shall
be null and void.

(h) Specific
Performance
. The parties agree that irreparable damage would occur in the event any provision of this Agreement was not performed
in accordance with the terms hereof, and, accordingly, that the parties shall be entitled to specific performance of the terms hereof,
in addition to any other remedy at law or inequity. Each of the parties hereby further waives (a) any defense in any action for specific
performance that a remedy at law would be adequate and (b) any requirement under any Law to post security or a bond as a prerequisite
to obtaining equitable relief.

(i) Governing
Law
. This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware applicable to Contracts

heard and determined exclusively in any Delaware Chancery Court; provided, that if jurisdiction is not then available in the Delaware
Chancery Court, then any such legal Action may be brought in any federal court located in the State of Delaware or any other Delaware

with respect to their respective properties for the purpose of any Action arising out of or relating to this Agreement brought by any
party hereto, and (b) agree not to commence any Action relating thereto except in the courts described above in Delaware, other than Actions

Each of the parties further agrees that notice as provided herein shall constitute sufficient service of process and the parties further
waive any argument that such service is insufficient. Each of the parties hereby irrevocably and unconditionally waives, and agrees not
to assert, by way of motion or as a defense, counterclaim or otherwise, in any Action arising out of or relating to this Agreement or
the transactions contemplated hereby, (i) any claim that it is not personally subject to the jurisdiction of the courts in Delaware as
described herein for any reason, (ii) that it or its property is exempt or immune from jurisdiction of any such court or from any legal
process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment,
execution of judgment or otherwise) and (iii) that (A) the Action in any such court is brought in an inconvenient forum, (B) the venue
of such Action is improper or (C) this Agreement, or the subject matter hereof, may not be enforced in or by such courts.

(j) Counterparts.
This Agreement may be executed and delivered (including by facsimile or portable document format (pdf) transmission) in counterparts,
and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original but all of
which taken together shall constitute one and the same agreement.

the mutual waivers and certifications in this Section 3.2(i).

(l) Further
Assurances
. Each party hereto shall execute and deliver or cause to be executed and delivered such additional documents and instruments

Exhibit 10.3 

 

Execution
Version

 

FORM
OF SUBSCRIPTION AGREEMENT

 

This
SUBSCRIPTION AGREEMENT (this “Subscription Agreement”) is entered into on July 6, 2021, by and between Athena Technology
Acquisition Corp., a Delaware corporation (the “Company”), and [●] (“Subscriber”).

 

WHEREAS,
concurrently with the execution of this Subscription Agreement, the Company is entering into a definitive Business Combination Agreement
(as may be amended, the “Business Combination Agreement” and the transactions contemplated by the Business Combination
Agreement, the “Transaction”), by and among the Company, HelioMax Merger Sub, Inc., a Delaware corporation (“Merger
Sub
”) and Heliogen, Inc., a Delaware corporation (f/k/a Edisun Heliostats, Inc.) (“Heliogen”) providing
for the combination of the Company and Heliogen;

 

WHEREAS,
in connection with the Transaction, Subscriber desires to subscribe for and purchase from the Company, immediately prior to the consummation
of the Transaction, that number of shares of the Company’s Class A common stock, par value $0.0001 per share (which, following
the closing of the Transaction, will be renamed “common stock” of Heliogen) (the “Common Stock”), set
forth on the signature page hereto (the “Subscribed Shares”) for a purchase price of $10.00 per share (the “Per
Share Price
” and the aggregate of such Per Share Price for all Subscribed Shares being referred to herein as the “Purchase
Price
”), and the Company desires to issue and sell to Subscriber the Subscribed Shares in consideration of the payment of the
Purchase Price by or on behalf of Subscriber to the Company; and

 

WHEREAS,
on or about the date of this Subscription Agreement, the Company is entering into other subscription agreements (each, an
Other Subscription Agreement”) with certain other accredited investors (the “Other
Subscribers
”), which are on the same terms as the terms of this Subscription Agreement (other than the number of shares of
Common Stock to be subscribed for and purchased by the Other Subscribers), pursuant to which such subscribers have agreed to
purchase on the closing date of the Transaction, inclusive of the Subscribed Shares, an aggregate amount of Sixteen Million, Five
Hundred Thousand (16,500,000) shares of Common Stock at the Per Share Price for an aggregate purchase price, inclusive of the
Purchase Price, of One Hundred Sixty-Five Million Dollars ($165,000,000).

 

NOW,
THEREFORE, in consideration of the foregoing and the mutual representations, warranties and covenants, and subject to the conditions,
herein contained, and intending to be legally bound hereby, the parties hereto hereby agree as follows:

 

1.
Subscription. Subject to the terms and conditions hereof, at the Closing (as defined below), Subscriber hereby agrees to
subscribe for and purchase from the Company, and the Company hereby agrees to issue and sell to Subscriber, upon the payment of the Purchase
Price, the Subscribed Shares (such subscription and issuance, the “Subscription”).

 

2.
Closing.

 

a.
The consummation of the Subscription contemplated hereby (the “Closing”) shall occur on the closing date of the Transaction
(the “Closing Date”) immediately prior to or concurrently with, and conditioned upon the effectiveness of, the consummation
of the Transaction.

 

b.
At least five (5) Business Days before the anticipated Closing Date, the Company shall deliver written notice to Subscriber (the “Closing
Notice
”) specifying (i) the anticipated Closing Date and (ii) the wire instructions for delivery of the Purchase Price to the
Company. No later than two (2) Business Days prior to the Closing Date as set forth in the Closing Notice, Subscriber shall deliver the
Purchase Price for the Subscribed Shares by wire transfer of United States dollars in immediately available funds to the account specified
by the Company in the Closing Notice, such funds to be held by the Company in escrow until the Closing. Upon satisfaction (or, if applicable,
waiver) of the conditions set forth in this Section 2, the Company shall deliver to Subscriber (i) at the Closing, the Subscribed Shares
in book entry form, free and clear of any liens or other restrictions (other than those arising under applicable securities laws), in
the name of Subscriber (or its nominee in accordance with its delivery instructions), and (ii) as promptly as practicable after the Closing,
evidence from the Company’s transfer agent of the issuance to Subscriber of the Subscribed Shares on and as of the Closing Date.
Notwithstanding the foregoing two sentences, for any Subscriber that informs the Company (1) that it is an investment company registered
under the Investment Company Act of 1940, as amended, (2) that it is advised by an investment adviser subject to regulation under the
Investment Advisers Act of 1940, as amended, or (3) that its internal compliance policies and procedures so require it, then, in lieu
of the settlement procedures in the foregoing two sentences, the following shall apply: such Subscriber shall deliver at 10:00 a.m. New
York City time on the Closing Date (or as soon as practicable following receipt of evidence from the Company’s transfer agent of
the issuance to Subscriber of the Subscribed Shares on and as of the Closing Date) the Purchase Price for the Subscribed Shares by wire
transfer of United States dollars in immediately available funds to the account specified by the Company in the Closing Notice (which
account shall not be an escrow account) against delivery by the Company to Subscriber of the Subscribed Shares in book entry form, free
and clear of any liens or other restrictions (other than those arising under applicable securities laws), in the name of Subscriber (or
its nominee in accordance with its delivery instructions) and evidence from the Company’s transfer agent of the issuance to Subscriber
of the Subscribed Shares on and as of the Closing Date. In the event that the consummation of the Transaction does not occur within two
(2) Business Days after the anticipated Closing Date specified in the Closing Notice, unless otherwise agreed to in writing by the Company
and the Subscriber, the Company shall promptly (but in no event later than three (3) Business Days after the anticipated Closing Date
specified in the Closing Notice) return the funds so delivered by Subscriber to the Company by wire transfer in immediately available
funds to the account specified by Subscriber, and any book entries shall be deemed cancelled. Notwithstanding such return or cancellation
(x) a failure to close on the anticipated Closing Date shall not, by itself, be deemed to be a failure of any of the conditions to Closing
set forth in this Section 2 to be satisfied or waived on or prior to the Closing Date, and (y) unless and until this Subscription Agreement
is terminated in accordance with Section 6 herein, Subscriber shall remain obligated (A) to redeliver funds to the Company following
the Company’s delivery to Subscriber of a new Closing Notice in accordance with this Section 2 and (B) to consummate the Closing
upon satisfaction of the conditions set forth in this Section 2. For the purposes of this Subscription Agreement, “Business
Day
” means any day other than a Saturday or Sunday, or any other day on which banks located in New York, New York are required
or authorized by law to be closed for business.

 

c.
The Closing shall be subject to the satisfaction or waiver in writing by the Company, on the one hand, or the Subscriber, on the other,
of the conditions that, on the Closing Date:

 

(i)
no suspension of the qualification of the Common Stock for sale or trading on the New York Stock Exchange (the “NYSE”),
or, to the Company’s knowledge, initiation or threatening of any proceedings for any of such purposes, shall have occurred, and
the Subscribed Shares shall have been approved for listing on the NYSE, subject to official notice of issuance;

 

(ii)
(i) all conditions precedent to the closing of the Transaction set forth in the Business Combination Agreement, including all necessary
approvals of the Company’s stockholders and regulatory approvals, if any, shall have been satisfied (as determined by the parties
to the Business Combination Agreement) or waived in writing by the person with the authority to make such waiver (other than those conditions
which, by their nature, are to be satisfied at the closing of the Transaction pursuant to the Business Combination Agreement), and the
closing of the Transaction shall be scheduled to occur on the Closing Date; and

 

(iii)
no governmental authority shall have enacted, issued, promulgated, enforced or entered any judgment, order, law, rule or regulation (whether
temporary, preliminary or permanent) which is then in effect and has the effect of making consummation of the transactions contemplated
hereby illegal or otherwise restraining, prohibiting or enjoining consummation of the transactions contemplated hereby; and no such governmental
authority shall have instituted or threatened in writing a proceeding seeking to impose any such restraint or prohibition.

 

d.
The obligation of the Company to consummate the Closing shall be subject to the satisfaction or waiver in writing by the Company of the
additional conditions that, on the Closing Date:

 

(i)
all representations and warranties of Subscriber contained in this Subscription Agreement are true and correct in all material respects
(other than representations and warranties that are qualified as to materiality, which representations and warranties shall be true in
all respects) at and as of the Closing Date; and

 

 

(ii)
Subscriber shall have performed, satisfied and complied in all material respects with all covenants, agreements and conditions required
by this Subscription Agreement to be performed, satisfied or complied with by it at or prior to the Closing.

 

e.
The obligation of Subscriber to consummate the Closing shall be subject to the satisfaction or waiver in writing by Subscriber of the
additional conditions that, on the Closing Date:

 

(i)
all representations and warranties of the Company contained in this Subscription Agreement are true and correct in all material respects
(other than representations and warranties that are qualified as to materiality or Company Material Adverse Effect (as defined below),
which representations and warranties shall be true in all respects) at and as of the Closing Date;

 

(ii)
the Company shall have performed, satisfied and complied in all material respects with all covenants, agreements and conditions required
by this Subscription Agreement to be performed, satisfied or complied with by it at or prior to the Closing;

 

(iii)
there shall have been no amendment, waiver or modification to the Business Combination Agreement that would reasonably be expected to
materially and adversely affect the economic benefits that Subscriber would reasonably expect to receive under this Subscription Agreement
without having received Subscriber’s prior written consent; and

 

(iv)
the Company shall not have entered into any Other Subscription Agreement with a lower purchase price per share of Common Stock or other
terms more favorable to such Other Subscriber or investor than as set forth in this Subscription Agreement and there shall have been
no amendment, waiver or modification to any such Other Subscription Agreement that materially benefits such Other Subscriber thereunder
unless the Subscriber has been offered the same benefits.

 

f.
Prior to or at the Closing, Subscriber shall deliver all such other information as is reasonably requested in order for the Company to
issue the Subscribed Shares to Subscriber, including, without limitation, the legal name of the person in whose name the Subscribed Shares
are to be issued (or the Subscriber’s nominee in accordance with its delivery instructions) and a duly completed and executed Internal
Revenue Service Form W-9 or appropriate form W-8.

 

3.
Company Representations and Warranties. For purposes of this Section 3, the term “Company” shall refer
to the Company as of the date hereof and, for purposes of only the representations contained in subsections (f), (i), (k) and (o) of
this Section 3, in each case, to the extent such representations and warranties are made as of the Closing Date, the combined
company after giving effect to the Transaction as of the Closing Date. The Company represents and warrants to Subscriber that:

 

a.
The Company (i) is duly organized and is validly existing and in good standing under the laws of the State of Delaware, (ii) has the
requisite power and authority to own, lease and operate its properties, to carry on its business as it is now being conducted and to
enter into and perform its obligations under this Subscription Agreement, and (iii) is duly licensed or qualified to conduct its business
and, if applicable, is in good standing under the laws of each jurisdiction (other than its jurisdiction of incorporation) in which the
conduct of its business or the ownership of its properties or assets requires such license or qualification, except, with respect to
the foregoing clause (iii), where the failure to be in good standing would not reasonably be expected to have a Company Material Adverse
Effect. For purposes of this Subscription Agreement, a “Company Material Adverse Effect” means any event, circumstance,
change, development, effect or occurrence (collectively “Effect”) that, individually or in the aggregate with all
other Effects, (a) is or would reasonably be expected to be materially adverse to the business, financial condition or results of operations
of the Company; or (b) would prevent, materially delay or materially impede the performance by the Company or Merger Sub of their respective
obligations under this Subscription Agreement or the consummation of the Transaction; provided, however, that none of the following shall
be deemed to constitute, alone or in combination, or be taken into account in the determination of whether, there has been or will be
a Company Material Adverse Effect: (i) any change or proposed change in or change in the interpretation of any statute, law, ordinance,
regulation, rule, code, executive order, injunction, judgment, decree or other order, in each case, of any governmental authority, or
United States generally accepted accounting principles after the date of this Subscription Agreement; (ii) any change or proposed changes
in or change in the interpretation in accounting or reporting principles, requirements or the Staff Statement on Accounting and Reporting
Considerations for Warrants Issued by Special Purpose Acquisition Companies on April 12, 2021 issued by the staff of the Division of
Corporation Finance (the “SEC Warrant Statement”); (iii) events or conditions generally affecting the industries or
geographic areas in which the Company operates; (iv) any downturn in general economic conditions, including changes in the credit, debt,
securities, financial or capital markets (including changes in interest or exchange rates, prices of any security or market index or
commodity or any disruption of such markets); (v) acts of war, sabotage, civil unrest or terrorism, or any escalation or worsening of
any such acts of war, sabotage, civil unrest or terrorism, or changes in global, national, regional, state or local political or social
conditions; (vi) any hurricane, tornado, flood, earthquake, natural disaster, or other acts of God, (vii) any actions taken or not taken
by the Company as required by this Subscription Agreement or any Other Subscription Agreement, (viii) any Effect attributable to the
announcement or execution, pendency, negotiation or consummation of the Transaction, or (ix) any actions taken, or failures to take action,
or such other changes or events, in each case, which the Subscriber has requested or to which it has consented or which actions are contemplated
by this Subscription Agreement, except in the cases of clauses (i) through (iv), to the extent that the Company is disproportionately
affected thereby as compared with other participants in the industry in which the Company operates.

 

 

b.
The Subscribed Shares have been duly authorized and, when issued and delivered to Subscriber against full payment therefor in accordance
with the terms of this Subscription Agreement, will be validly issued, fully paid and non-assessable, and will not have been issued in
violation of any preemptive rights created under the Company’s organizational documents or the laws of the State of Delaware.

 

c.
The Subscribed Shares are not, and following the Closing, will not be, subject to any Transfer Restriction. The term “Transfer
Restriction
” means any condition to or restriction on the ability of the undersigned or any other holder of the Subscribed
Shares to pledge, sell, assign or otherwise transfer the Subscribed Shares under any organizational document, policy or agreement of,
by or with the Company, but excluding the restrictions on transfer described in Section 4(e) of this Subscription Agreement with respect
to the status of the Subscribed Shares as “restricted securities” pending their registration for resale under the Securities
Act of 1933, as amended (the “Securities Act”) in accordance with the terms of this Subscription Agreement.

 

d.
This Subscription Agreement has been, and the Business Combination Agreement will be, duly authorized, executed and delivered by the
Company, and assuming the due authorization, execution and delivery of the same by the other parties thereto, shall constitute the valid
and legally binding obligation of the Company, enforceable against the Company in accordance with their terms, except as such enforceability
may be limited by bankruptcy, insolvency, reorganization, moratorium and similar laws affecting creditors generally and by the availability
of equitable remedies.

 

e.
The execution, delivery and performance of this Subscription Agreement, the issuance and sale of the Subscribed Shares and the compliance
by the Company with all of the provisions of this Subscription Agreement and the consummation of the transactions contemplated herein
will not conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, or result

a party or by which the Company is bound or to which any of the property or assets of the Company is subject; (ii) the organizational

b.
This Subscription Agreement has been duly executed and delivered by Subscriber, and assuming the due authorization, execution and delivery
of the same by the Company, this Subscription Agreement shall constitute the valid and legally binding obligation of Subscriber, enforceable
against Subscriber in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, reorganization,
moratorium and similar laws affecting creditors generally and by the availability of equitable remedies.

 

c.
The execution and delivery of this Subscription Agreement, the purchase of the Subscribed Shares and the compliance by Subscriber with
all of the provisions of this Subscription Agreement and the consummation of the transactions contemplated herein will not conflict with
or result in a breach or violation of any of the terms or provisions of, or constitute a default under, or result in the creation or
imposition of any lien, charge or encumbrance upon any of the property or assets of Subscriber pursuant to the terms of (i) any material
indenture, mortgage, deed of trust, loan agreement, lease, license or other agreement or instrument to which Subscriber is a party or
by which Subscriber is bound or to which any of the property or assets of Subscriber is subject; (ii) the organizational documents of
Subscriber; or (iii) any statute or any judgment, order, rule or regulation of any court or governmental agency or body, domestic or
foreign, having jurisdiction over Subscriber or any of its properties that, in the case of clauses (i) and (iii), would reasonably be
expected to have a material adverse effect on Subscriber’s ability to consummate the transactions contemplated hereby, including
the purchase of the Subscribed Shares.

 

d.
Subscriber (i) is a “qualified institutional buyer” (as defined in Rule 144A under the Securities Act) or an “accredited

account is a “qualified institutional buyer” (as defined in Rule 144A under the Securities Act) or an “accredited investor”
(within the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act) and Subscriber has full investment discretion with respect
to each such account, and the full power and authority to make the acknowledgements, representations and agreements herein on behalf
of each owner of each such account, and (iii) is not acquiring the Subscribed Shares with a view to, or for offer or sale in connection
with, any distribution thereof in violation of the Securities Act (and has provided the Company with the requested information on Annex

e.
Subscriber understands that the Subscribed Shares are being offered in a transaction not involving any public offering within the meaning
of the Securities Act and that the Subscribed Shares have not been registered under the Securities Act. Subscriber understands that the
Subscribed Shares may not be offered, resold, transferred, pledged or otherwise disposed of by Subscriber absent an effective registration
statement under the Securities Act, except (i) to the Company or a subsidiary thereof, (ii) pursuant to a stock lending program, or (iii)
pursuant to an applicable exemption from the registration requirements of the Securities Act, and, in each of cases (i) and (ii), in
accordance with any applicable securities laws of the applicable states and other jurisdictions of the United States, and that any book-entry

Subscriber understands that Subscriber may not be able to readily resell the Subscribed Shares and may be required to bear the financial
risk of an investment in the Subscribed Shares for an indefinite period of time. Subscriber acknowledges and agrees that the Subscribed
Shares will not be eligible for offer, resale or disposition pursuant to Rule 144 promulgated under the Securities Act until at least
one year from the Closing Date. Subscriber understands that it has been advised to consult legal counsel prior to making any offer, resale,
pledge or transfer of any of the Subscribed Shares. Subscriber acknowledges and agrees that it does not currently have, and it will not
before Closing enter into, any binding commitment to transfer any of the Subscribed Shares.

 

 

Each
book entry for the Subscribed Shares shall contain a notation, and each certificate (if any) evidencing the Subscribed Shares shall be
stamped or otherwise imprinted with a legend, in substantially the following form:

 

THE
SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED, OR THE SECURITIES
LAWS OF ANY STATE OR OTHER JURISDICTION, AND MAY NOT BE OFFERED OR TRANSFERRED BY SALE, ASSIGNMENT, PLEDGE OR OTHERWISE UNLESS (I) A
REGISTRATION STATEMENT FOR THESE SECURITIES UNDER THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS IS IN EFFECT OR (II) THE COMPANY
HAS RECEIVED AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY TO THE EFFECT THAT SUCH REGISTRATION IS NOT REQUIRED.

 

f.
Subscriber and its investment advisor, as applicable, agrees that Subscriber is purchasing the Subscribed Shares directly from the Company.
Subscriber further acknowledges that there have not been, and Subscriber hereby agrees that it is not relying on, any representations,
warranties, covenants or agreements made to Subscriber by the Company, any other party to the Transaction or any other person or entity
(including the Placement Agent, and after the Closing, Heliogen), expressly or by implication, other than those representations, warranties,
covenants and agreements of the Company set forth in this Subscription Agreement, and Subscriber is not relying on any representations,
warranties or covenants other than those expressly set forth herein. Subscriber acknowledges that certain information provided by the
Company was based on projections, and such projections were prepared based on assumptions and estimates that are inherently uncertain
and are subject to a wide variety of significant business, economic and competitive risks and uncertainties that could cause actual results
to differ materially from those contained in the projections.

 

g.
In making its decision to purchase the Subscribed Shares, Subscriber or its investment advisor, as applicable, has relied solely upon
independent investigation made by Subscriber. Without limiting the generality of the foregoing, Subscriber or its investment advisor,
as applicable, has not relied on any statements or other information provided by anyone other than the Company concerning the Company
or the Subscribed Shares or the offer and sale of the Subscribed Shares. Subscriber or its investment advisor, as applicable, acknowledges
and agrees that Subscriber has received access to, and has had an adequate opportunity to review, such information as Subscriber deems
necessary in order to make an investment decision with respect to the Subscribed Shares. Subscriber or its investment advisor, as applicable,
acknowledges and agrees that neither the Placement Agent nor any affiliate of the Placement Agent, has provided Subscriber or its investment
advisor, as applicable, with any advice with respect to the Subscribed Shares nor is such information or advice necessary or desired.
Neither the Placement Agent nor any affiliate of the Placement Agent and, except for the representations and warranties contained in
this Subscription Agreement, none of the Company, Heliogen or any of their respective affiliates, has made or makes any representation
as to the Company, Heliogen or the quality or value of the Subscribed Shares and any non-public information with respect to the Company
or Heliogen which any such parties may have acquired need not be provided to Subscriber or its investment advisor, as applicable. However,
neither any inquiries, nor any due diligence investigation conducted by Subscriber or any of Subscriber’s professional advisors
nor anything else contained herein, shall modify, limit or otherwise affect Subscriber’s right to rely on the Company’s representations,
warranties, covenants and agreements contained in this Subscription Agreement. In connection with the issuance of the Subscribed Shares
to Subscriber, none of the Placement Agent, any affiliate of the Placement Agent, or the Company, Heliogen or any of their respective
affiliates has acted as a financial advisor or fiduciary to Subscriber. The Subscriber agrees that the Placement Agent shall not be liable
to any Subscriber for any action heretofore or hereafter taken or omitted to be taken by any of them in connection with the Subscriber’s
purchase of the Subscribed Shares.

 

 

h.

(including, without limitation, attorneys, accountants, bankers, consultants and financial advisors), agents, control persons, representatives,
affiliates, directors, officers, managers, members, and/or employees, and/or the representatives of such persons (such parties referred
to collectively as “Representatives”). The Subscribed Shares were offered to Subscriber solely by direct contact between
Subscriber and the Company, the Placement Agent, Heliogen and/or their respective Representatives. Subscriber acknowledges that it is
not relying upon, and has not relied upon, any statement, representation or warranty made by any person or entity (including, without
limitation, the Company, Heliogen and/or their respective Representatives), other than the representations and warranties contained in
this Subscription Agreement, in making its investment or decision to invest in the Company. Subscriber did not become aware of this offering
of the Subscribed Shares, nor were the Subscribed Shares offered to Subscriber, by any other means, and none of the Company, the Placement
Agent, Heliogen or their respective Representatives acted as investment advisor, broker or dealer to Subscriber. Subscriber acknowledges
that the Company represents and warrants that the Subscribed Shares (i) were not offered by any form of general solicitation or general
advertising and (ii) are not being offered in a manner involving a public offering under, or in a distribution in violation of, the Securities
Act, or any state securities laws.

and ownership of the Subscribed Shares. Subscriber or its investment advisor, as applicable, has such knowledge and experience in financial
and business matters as to be capable of evaluating the merits and risks of an investment in the Subscribed Shares, and Subscriber or
its investment advisor, as applicable, has had an opportunity to seek, and has sought, such accounting, legal, business and tax advice
as Subscriber has considered necessary to make an informed investment decision. Subscriber or its investment advisor, as applicable,
acknowledges that it is a sophisticated investor, experienced in investing in private equity transaction and capable of evaluating investment
risks independently, both in general and with regard to all transactions and investment strategies involving a security or securities.

 

j.
Alone, or together with any professional advisor(s), Subscriber represents and acknowledges that Subscriber has adequately analyzed and
fully considered the risks of an investment in the Subscribed Shares and determined that the Subscribed Shares are a suitable investment
for Subscriber and that Subscriber is able at this time and in the foreseeable future to bear the economic risk of a total loss of Subscriber’s
investment in the Company. Subscriber acknowledges specifically that a possibility of total loss exists.

5.
Registration of Subscribed Shares.

 

a.
The Company agrees that, within thirty (30) calendar days following the Closing Date (the “Filing Deadline”), the
Company will file with the Commission (at the Company’s sole cost and expense) a registration statement registering the resale
of the Subscribed Shares (the “Registration Statement”), and the Company shall use its commercially reasonable efforts
to have the Registration Statement declared effective as soon as practicable after the filing thereof, but in any event no later than
sixty (60) calendar days after the Closing Date (the “Effectiveness Deadline”); provided, that the Effectiveness
Deadline shall be extended to ninety (90) calendar days after the Closing Date if the Registration Statement is reviewed by, and comments
thereto are provided from, the Commission; provided, further that the Company shall have the Registration Statement declared
effective within five (5) Business Days after the date the Company is notified (orally or in writing, whichever is earlier) by the staff
of the Commission that the Registration Statement will not be “reviewed” or will not be subject to further review and that
if the Effectiveness Deadline falls on a Saturday, Sunday or other day that the Commission is closed for business, the Effectiveness
Deadline shall be extended to the next Business Day on which the Commission is open for business. Without limiting the foregoing, the
Company’s obligations to include the Subscribed Shares in the Registration Statement are contingent upon the undersigned furnishing
in writing to the Company such information regarding the undersigned, the securities of the Company held by the undersigned and the intended
method of disposition of the Subscribed Shares as shall be reasonably requested by the Company to effect the registration of the Subscribed
Shares, and shall execute such documents in connection with such registration as the Company may reasonably request that are customary
of a selling stockholder in similar situations; provided that Subscriber shall not in connection with the foregoing be required to execute
any lock-up or similar agreement or otherwise be subject to any contractual restriction on the ability to transfer the Subscribed Shares.
Unless required under applicable laws and Commission rules, in no event shall the Subscriber be identified as a statutory underwriter
in the Registration Statement; provided that if the Subscriber is required to be so identified as a statutory underwriter in the Registration
Statement, the Subscriber will have an opportunity to withdraw its Subscribed Shares from the Registration Statement. Notwithstanding
the foregoing, if the Commission prevents the Company from including any or all of the shares of Common Stock proposed to be registered
under the Registration Statement due to limitations on the use of Rule 415 of the Securities Act for the resale of shares of Common Stock
by the applicable stockholders or otherwise, such Registration Statement shall register for resale such number of the shares that is
equal to the maximum number of the shares as is permitted by the Commission. In such event, the number of shares to be registered for
each selling stockholder named in the Registration Statement shall be reduced pro rata among all such selling stockholders and as promptly
as practicable after being permitted to register additional shares under Rule 415 under the Securities Act, the Company shall amend the
Registration Statement or file a new Registration Statement to register such additional shares and cause such amendment or Registration
Statement to become effective as promptly as practicable. The Company will use its commercially reasonable efforts to maintain the continuous
effectiveness of the Registration Statement, and to supplement and amend the Registration Statement to the extent necessary to ensure
that such Registration Statement is available or, if not available, that another registration statement is available for the resale of
the Subscribed Shares, until the earliest of (i) the date on which all of the Subscribed Shares may be resold without volume or manner
of sale limitations pursuant to Rule 144 promulgated under the Securities Act and, so long as Subscriber is not an “affiliate”
of the Company, without the requirement that the Company be in compliance with the current public information required under Rule 144(c)(1)
(or Rule 144(i)(2), if applicable), (ii) the date on which all of the Subscribed Shares have actually been sold pursuant to Rule 144
or another exemption from registration or pursuant to the Registration Statement and (iii) the date which is three years after the Closing.
For purposes of clarification, any failure by the Company to file the Registration Statement by the Filing Deadline or to effect such
Registration Statement by the Effectiveness Deadline shall not otherwise relieve the Company of its obligations to file or effect the
Registration Statement set forth in this Section 5.

 

b.
Notwithstanding anything to the contrary in this Subscription Agreement, the Company shall be entitled to delay or postpone the effectiveness
of the Registration Statement, and from time to time to require any Subscriber not to sell under the Registration Statement or to suspend
the effectiveness thereof, if the negotiation or consummation of a transaction by the Company or its subsidiaries is pending or an event
has occurred, which negotiation, consummation or event, the Company’s board of directors reasonably believes, upon the advice of
legal counsel, would require additional disclosure by the Company in the Registration Statement of material information that the Company
has a bona fide business purpose for keeping confidential and the non-disclosure of which in the Registration Statement would be expected,
in the reasonable determination of the Company’s board of directors, upon the advice of legal counsel, to cause the Registration
Statement to fail to comply with applicable disclosure requirements (each such circumstance, a “Suspension Event”);
provided, however, that the Company may not delay or suspend the Registration Statement on more than two occasions or for
more than sixty (60) consecutive calendar days, or more than ninety (90) total calendar days, in each case during any twelve-month period.
Upon receipt of any written notice from the Company of the happening of any Suspension Event (which notice shall not contain material
non-public information) during the period that the Registration Statement is effective or if as a result of a Suspension Event the Registration
Statement or related prospectus contains any untrue statement of a material fact or omits to state any material fact required to be stated
therein or necessary to make the statements therein, in light of the circumstances under which they were made (in the case of the prospectus)
not misleading, Subscriber agrees that (i) it will immediately discontinue offers and sales of the Subscribed Shares under the Registration
Statement (excluding, for the avoidance of doubt, sales conducted pursuant to Rule 144) until such Subscriber receives copies of a supplemental
or amended prospectus (which the Company agrees to promptly prepare) that corrects the misstatement(s) or omission(s) referred to above
and receives notice that any post-effective amendment has become effective or unless otherwise notified by the Company that it may resume
such offers and sales, and (ii) it will maintain the confidentiality of any information included in such written notice delivered by
the Company unless otherwise required by law or subpoena. If so directed by the Company, Subscriber will deliver to the Company or, in
such Subscriber’s sole discretion destroy, all copies of the prospectus covering the Subscribed Shares in such Subscriber’s
possession; provided, however, that this obligation to deliver or destroy all copies of the prospectus covering the Subscribed Shares
shall not apply (i) to the extent such Subscriber is required to retain a copy of such prospectus (a) in order to comply with applicable
legal, regulatory, self-regulatory or professional requirements or (b) in accordance with a bona fide pre-existing document retention
policy or (ii) to copies stored electronically on archival servers as a result of automatic data back-up.

 

 

c.
In the case of the registration effected by the Company pursuant to his Section 5, the Company shall, upon reasonable request of Subscriber,
inform Subscriber as to the status of such registration. At its reasonable expense the Company shall:

 

(i)
Advise Subscriber within 2 Business Days:

 

1.
when a Registration Statement or any amendment thereto has been filed with the Commission and when such Registration Statement or any
post-effective amendment thereto has become effective;

 

2.
of any written request by the Commission for amendments or supplements to any Registration Statement or the prospectus included therein
or for additional information;

 

3.
of the issuance by the Commission of any stop order suspending the effectiveness of any Registration Statement or the initiation of any
proceedings for such purpose;

 

4.
of the receipt by the Company of any notification with respect to the suspension of the qualification of the Subscribed Shares included
therein for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and

 

5.
subject to the provisions in this Subscription Agreement, of the occurrence of any event that requires the making of any changes in any
Registration Statement or prospectus so that, as of such date, the statements therein are not misleading and do not omit to state a material
fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in the light of the circumstances
under which they were made) not misleading (provided that any such notice pursuant to this Section 5(c)(i)(5) shall solely provide that
the use of the Registration Statement or prospectus has been suspended without setting forth the reason for such suspension).

 

Notwithstanding
anything to the contrary set forth herein, the Company shall not, when so advising the Subscriber of such events, provide Subscriber
with any material, nonpublic information regarding the Company other than to the extent that providing notice to the Subscriber of the
occurrence of the events listed in (1) through (5) above constitutes material, nonpublic information regarding the Company;

 

(ii)
use commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of any Registration Statement
as soon as reasonably practicable;

 

(iii)
upon the occurrence of any Suspension Event, except for such times as the Company is permitted hereunder to suspend, and has suspended,
the use of a prospectus forming part of a Registration Statement, the Company shall use its commercially reasonable efforts to as soon
as reasonably practicable prepare a post-effective amendment to such Registration Statement or a supplement to the related prospectus,
or file any other required document so that, as thereafter delivered to purchasers of the Subscribed Shares included therein, such prospectus
will not include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein,
in the light of the circumstances under which they were made, not misleading;

 

 

(iv)
use its commercially reasonable efforts to cause all Subscribed Shares held by Subscriber to be listed on each securities exchange or
market, if any, on which the Subscribed Shares have been listed;

 

(v)
use its commercially reasonable efforts to take all other steps necessary to effect the registration of the Subscribed Shares contemplated
hereby and to enable Subscriber to sell the Subscribed Shares under Rule 144 (when available), including to (x) make and keep public
information available, as those terms are understood and defined in Rule 144, (y) file all reports and other materials required to be
filed by the Exchange Act so long as the Company remains subject to such requirements and the filing of such reports and other documents
is required for the applicable provisions of Rule 144, and (z) furnish to Subscriber, promptly upon request, (A) a written statement
by the Company, if true, that it has complied with the reporting requirements of Rule 144, the Securities Act and the Exchange Act, (B)
a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company, and
(C) such other information as may reasonably be requested to enable Subscriber to sell the Subscribed Shares under Rule 144 without registration;
and without the requirement that the Company be in compliance with the current public information required under Rule 144(c)(1) (or Rule
144(i)(2), if applicable); and

 

(vi)
for as long as the Subscriber holds Subscribed Shares, use its commercially reasonable efforts to cause the Company’s transfer
agent to remove any restrictive legend when the Subscribed Shares are sold pursuant to Rule 144 under the Securities Act or the Registration
Statement within two (2) Business Days of request by the Subscriber. In connection therewith, (A) Subscriber shall provide customary
representation letters reasonably acceptable to the Company and the Company’s transfer agent, (B) if required by the Company’s
transfer agent, the Company will promptly cause an opinion of counsel to be delivered to its transfer agent, together with any other
authorizations, certificates and directions reasonably requested by the Company in order to render such opinion and/or required by the
transfer agent that authorize and direct the transfer agent to issue such Subscribed Shares without any such legend and (C) the Company
shall be responsible for the fees of its transfer agent, legal counsel and any DTC fees associated with such issuance.

 

d.
If the total number of shares of Common Stock that the Subscriber and any other person(s) intend to include in an underwritten offering
exceeds the number of shares of Common Stock that can be sold in an underwritten offering without being likely to have an adverse effect
on the price, timing or distribution of shares of the Common Stock offered or the market for the shares of Common Stock, then the shares
of Common Stock to be included in such offering shall include the number of shares of Common Stock that the managing underwriter of the
offering advises the Company can be sold without having such adverse effect, with such number to be allocated (i) first, to the Company
or other party or parties initiating such registration and (ii) second, to the Subscriber and the other holders of shares of Common Stock
with registration rights entitling them to participate in such underwritten offering, allocated among the Subscriber and such other holders
pro rata on the basis of the number of shares of Common Stock proposed to be sold by each applicable holder in such underwritten offering
(based, for each such participant described in this clause (ii), on the percentage derived by dividing (x) the number of shares of Common
Stock proposed to be sold by such participant in such underwritten offering by (y) the aggregate number of shares of Common Stock proposed
to be sold by all such participants) or in such manner as they may agree. In such event, the number of shares to be registered for each
selling stockholder named in the Registration Statement shall be reduced pro rata among all such selling stockholders and, as promptly
as practicable after the managing underwriter of the offering advises the Company additional shares can be sold without being likely
to have an adverse effect on the price, timing or distribution of shares of the Common Stock that may be offered or the market for the
shares of Common Stock, then and the Company is otherwise permitted to register additional shares, the Company shall amend the Registration
Statement or file a new Registration Statement to register such additional shares of Common Stock that were originally proposed to be
sold by each applicable holder in such underwritten offering that were not registered and cause such amendment or Registration Statement
to become effective as promptly as practicable.

 

 

e.
The Company shall, notwithstanding any termination of this Subscription Agreement, indemnify, defend and hold harmless Subscriber (to
the extent a seller under the Registration Statement), and its officers, directors, investment advisers and agents, and each person who
controls such Subscriber (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) to the fullest extent
permitted by applicable law, from and against any and all losses, claims, damages, liabilities, costs (including, without limitation,
reasonable attorneys’ fees) and expenses (collectively, “Losses”), that arise out of or are based upon (i) any
untrue or alleged untrue statement of a material fact contained in the Registration Statement, any prospectus included in the Registration
Statement or any form of prospectus or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or
relating to any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements
therein (in the case of any prospectus or form of prospectus or supplement thereto, in light of the circumstances under which they were
made) not misleading, or (ii) any violation or alleged violation by the Company of the Securities Act, Exchange Act or any state securities
law or any rule or regulation thereunder, in connection with the performance of its obligations under this Section 5, except to
the extent, but only to the extent, that such untrue statements, alleged untrue statements, omissions or alleged omissions are based
upon and in conformity with information regarding such Subscriber furnished in writing to the Company by or on behalf of such Subscriber
expressly for use therein or such Subscriber has omitted a material fact from such information; provided, however, that
the indemnification contained in this Section 5 shall not apply to amounts paid in settlement of any Losses if such settlement
is effected by or on behalf of the Subscriber without the consent of the Company (which consent shall not be unreasonably withheld, conditioned
or delayed), nor shall the Company be liable for any Losses to the extent they arise out of or are based upon a violation which occurs
(A) in connection with any failure of the Subscriber to deliver or cause to be delivered a prospectus made available to the Subscriber
by or on behalf of the Company in a timely manner, (B) as a result of offers or sales effected by or on behalf of the Subscriber by means
of a freewriting prospectus (as defined in Rule 405) that was not authorized in writing by the Company, or (C) in connection with any
offers or sales effected by or on behalf of a Subscriber in violation of Section 5(b) of this Subscription Agreement. The Company
shall notify such Subscriber promptly of the institution, threat or assertion of any proceeding arising from or in connection with the
transactions contemplated by this Section 5 of which the Company is aware. The indemnity set forth in this Section 5(c)
shall remain in full force and effect regardless of any investigation made by or on behalf of an indemnified party and shall survive
the transfer of the Subscribed Shares by such Subscriber.

 

f.
The Subscriber may deliver written notice (an “Opt-Out Notice”) to the Company requesting that the Subscriber not
receive notices from the Company otherwise required by Section 5(e); provided, however, that the Subscriber may later revoke any such
Opt-Out Notice in writing. Following receipt of an Opt-Out Notice from the Subscriber (unless subsequently revoked), (i) the Company
shall not deliver any such notices to the Subscriber and the Subscriber shall no longer be entitled to the rights associated with any
such notice and (ii) each time prior to the Subscriber’s intended use of an effective Registration Statement, the Subscribers will
notify the Company in writing at least two (2) Business Days in advance of such intended use, and if a notice of a Suspension Event was
previously delivered (or would have been delivered but for the provisions of this Section 8(c)) and the related suspension period remains
in effect, the Company will so notify the Subscriber, within one (1) Business Day of the Subscriber’s notification to the Company,
by delivering to the Subscriber a copy of such previous notice of Suspension Event, and thereafter will provide the Subscriber with the
related notice of the conclusion of such Suspension Event promptly following its availability.

 

g.
Subscriber shall, severally and not jointly with any Other Subscriber or any other selling stockholder named in the registration statement,
indemnify and hold harmless the Company, its directors, officers, agents and employees, and each person who controls the Company (within
the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), to the fullest extent permitted by applicable law,
from and against all Losses, as incurred, arising out of or based upon any untrue or alleged untrue statement of a material fact contained
in the Registration Statement, any prospectus included in the Registration Statement, or any form of prospectus, or in any amendment
or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission of a material
fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus, or any form of prospectus
or supplement thereto, in light of the circumstances under which they were made) not misleading, in any such case to the extent, but
only to the extent, that such untrue statements, alleged untrue statements, or omissions or alleged omissions are based upon and in conformity
with information regarding such Subscriber furnished in writing to the Company by such Subscriber expressly for use therein; provided,
however, that the indemnification contained in this Section 5 shall not apply to amounts paid in settlement of any Losses
if such settlement is effected without the consent of such Subscriber (which consent shall not be unreasonably withheld, conditioned
or delayed). In no event shall the liability of any Subscriber be greater in amount than the dollar amount of the net proceeds received
by such Subscriber upon the sale of the Subscribed Shares giving rise to such indemnification obligation. Subscriber shall notify the
Company promptly of the institution, threat or assertion of any proceeding arising from or in connection with the transactions contemplated
by this Section 5 of which such Subscriber is aware. Such indemnity shall remain in full force and effect regardless of any investigation
made by or on behalf of an indemnified party and shall survive the transfer of the Subscribed Shares by such Subscriber.

 

 

6.
Termination. This Subscription Agreement shall terminate and be void and of no further force and effect, and all rights and obligations
of the parties hereunder shall terminate without any further liability on the part of any party in respect thereof, upon the earlier
to occur of (a) such date and time as either Business Combination Agreement is terminated in accordance with its terms, (b) upon the
mutual written agreement of the parties to terminate this Subscription Agreement, (c) if, on the Closing Date of the Transaction, any
of the conditions to Closing set forth in Section 2 of this Subscription Agreement have not been satisfied as of the time required
hereunder to be so satisfied or waived (to the extent a waiver is capable of being issued) by the party entitled to grant such waiver
and, as a result thereof, the transactions contemplated by this Subscription Agreement are not consummated, or (d) December 31, 2021;
provided, that nothing herein will relieve any party from liability for any willful breach hereof (including, for the avoidance of doubt,
a Subscriber’s willful breach of Section 2(c) of this Subscription Agreement with respect to its representations, warranties
and covenants as of the date of the Closing) prior to the time of termination, and each party will be entitled to any remedies at law
or in equity to recover losses, liabilities or damages arising from such breach. The Company shall notify Subscriber of the termination
of either Business Combination Agreement promptly after the termination thereof. For the avoidance of doubt, if any termination hereof
occurs after the delivery by the Subscriber of the Purchase Price for the Subscribed Shares, the Company shall promptly (but not later
than one (1) Business Day thereafter) return the Purchase Price to the Subscriber without any deduction for or on account of any tax,
tax withholding, tax charges, or set-off for taxes.

 

7.
Trust Account Waiver. Subscriber hereby acknowledges that the Company has established a trust account (the “Trust Account”)
containing the proceeds of its initial public offering (the “IPO”) and from certain private placements occurring simultaneously
with the IPO (including interest accrued from time to time thereon) for the benefit of the Company’s public stockholders and certain
other parties (including the underwriters of the IPO). For and in consideration of the Company entering into this Subscription Agreement,
and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Subscriber hereby (i) agrees
that it does not now and shall not at any time hereafter have any right, title, interest or claim of any kind in or to any assets held
in the Trust Account, and shall not bring any action, suit, claim or other proceeding against the Trust Account, regardless of whether
such claim arises as a result of, in connection with or relating in any way to this Subscription Agreement, the transactions contemplated
hereby, the Subscribed Shares or any other matter, and regardless of whether such claim arises based on contract, tort, equity or any
other theory of legal liability (any and all such claims are collectively referred to hereafter as the “Released Claims”),
(ii) irrevocably waives any Released Claims that it may have against the Trust Account now or in the future as a result of, or arising
out of, any negotiations, contracts or agreements with the Company, and (iii) will not seek recourse against the Trust Account for any
reason whatsoever; provided however, that nothing in this Section 7 shall be deemed to limit any Subscriber’s right to distributions
from the Trust Account in accordance with the Company’s amended and restated certificate of incorporation in respect of any redemptions
by Subscriber of its shares of public Common Stock of the Company acquired by any means other than pursuant to this Subscription Agreement.
The Subscriber acknowledges and agrees that it shall not have any redemption rights with respect to the Subscribed Shares pursuant to
the Company’s organizational documents in connection with the Transaction or any other business combination, any subsequent liquidation
of the Trust Account, the Company or otherwise. In the event Subscriber has any claim against the Company as a result of, or arising
out of, this Subscription Agreement, the transactions contemplated hereby or the Subscribed Shares, it shall pursue such claim solely
against the Company and its assets outside the Trust Account and not against the Trust Account or any monies or other assets in the Trust
Account.

and the Placement Agent if it becomes aware that any of the acknowledgments, understandings, agreements, representations and warranties
of Subscriber set forth herein are no longer accurate in all material respects. Subscriber acknowledges and agrees that the purchase
by Subscriber of Subscribed Shares from the Company will constitute a reaffirmation of the acknowledgments, understandings, agreements,
representations and warranties herein (as modified by any such notice) by Subscriber as of the time of such purchase except to the extent
that any such representation and warranty expressly speaks as of an earlier date, in which case such representation and warranty shall
be true and correct in all material respects (other than representations and warranties that are qualified as to materiality, which representations
and warranties shall be true and correct in all respects) as of such earlier date. The Company acknowledges that Subscriber and others

d.
Each party shall pay all of its own expenses in connection with this Subscription Agreement and the transactions contemplated herein.

 

e.
Neither this Subscription Agreement nor any rights that may accrue to Subscriber hereunder (other than the Subscribed Shares acquired
hereunder, if any) may be transferred or assigned by Subscriber. Neither this Subscription Agreement nor any rights that may accrue to
the Company hereunder may be transferred or assigned (provided, that, for the avoidance of doubt, the Company may transfer its rights
(but not obligations) hereunder solely in connection with the consummation of the Transaction and exclusively to another entity under
the control of, or under common control with, the Company). Notwithstanding the foregoing, Subscriber may assign its rights and obligations
under this Subscription Agreement to one or more of its affiliates (including other investment funds or accounts managed or advised by
the investment manager who acts on behalf of the Subscriber or by an affiliate of such investment manager) or, with the Company’s
prior written consent, to another person that is eligible to enter into this Subscription Agreement, provided that no such assignment
shall relieve Subscriber of its obligations hereunder if any such assignee fails to perform such obligations, unless the Company and

f.
All the agreements, representations and warranties made by each party hereto in this Subscription Agreement shall survive the Closing.

provided that Company agrees to keep any such information provided by Subscriber confidential, except (A) as required by the federal
securities laws, rules or regulations and (B) to the extent such disclosure is required by other laws, rules or regulations, at the request
of the staff of the Commission or regulatory agency or under the regulations of the NYSE. Subscriber acknowledges that the Company may

m.
Remedies.

 

(i)
The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Subscription Agreement were
not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be
entitled to an injunction or injunctions to prevent breaches of this Subscription Agreement and to enforce specifically the terms and
provisions of this Subscription Agreement, this being in addition to any other remedy to which such party is entitled at law, in equity,
in contract, in tort or otherwise.

 

(ii)
Each of the parties hereto shall be entitled to seek and obtain equitable relief, without proof of actual damages, including an injunction
or injunctions or order for specific performance to prevent breaches of this Subscription Agreement and to enforce specifically the terms
and provisions of this Subscription Agreement to cause Subscriber to fund the Purchase Price and cause the Closing to occur if the conditions
in Section 2 of this Subscription Agreement have been satisfied or, to the extent permitted by applicable law, waived by the applicable
party entitled to waive any such condition. The parties hereto further agree (i) to waive any requirement for the security or posting
of any bond in connection with any such equitable remedy, (ii) not to assert that a remedy of specific enforcement pursuant to this Section
8(m)
is unenforceable, invalid, contrary to applicable law or inequitable for any reason and (iii) to waive any defense that a remedy
at law would be adequate. In any dispute arising out of or related to this Subscription Agreement, or any other agreement, document,
instrument or certificate contemplated hereby, or any transactions contemplated hereby or thereby, the applicable adjudicating body shall

with the dispute and the enforcement of its rights under this Subscription Agreement or any other agreement, document, instrument or
certificate contemplated hereby and, if the adjudicating body determines a party to be the prevailing party under circumstances where
the prevailing party won on some but not all of the claims and counterclaims, the adjudicating body may award the prevailing party an
appropriate percentage of the costs and attorneys’ fees reasonably incurred by the prevailing party in connection with the adjudication
and the enforcement of its rights under this Subscription Agreement or any other agreement, document, instrument or certificate contemplated
hereby or thereby.

 

n.
This Subscription Agreement shall be governed by, and construed in accordance with, the laws of the State of New York, without regard
to the principles of conflicts of laws that would otherwise require the application of the law of any other state.

BY ANY PARTY AGAINST ANY OTHER PARTY OR ANY AFFILIATE OF ANY OTHER SUCH PARTY, WHETHER WITH RESPECT TO CONTRACT CLAIMS, TORT CLAIMS OR
OTHERWISE. THE PARTIES AGREE THAT ANY SUCH CLAIM OR CAUSE OF ACTION SHALL BE TRIED BY A COURT TRIAL WITHOUT A JURY. WITHOUT LIMITING
THE FOREGOING, THE PARTIES FURTHER AGREE THAT THEIR RESPECTIVE RIGHT TO A TRIAL BY JURY IS WAIVED BY OPERATION OF THIS SECTION AS TO
ANY ACTION, COUNTERCLAIM OR OTHER PROCEEDING WHICH SEEKS, IN WHOLE OR IN PART, TO CHALLENGE THE VALIDITY OR ENFORCEABILITY OF THIS SUBSCRIPTION
AGREEMENT OR ANY PROVISION HEREOF. THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS

the “Designated Courts”). Each party hereby consents and submits to the exclusive jurisdiction of the Designated Courts.
No legal action, suit or proceeding with respect to this Subscription Agreement may be brought in any other forum. Each party hereby
irrevocably waives all claims of immunity from jurisdiction, and any objection which such party may now or hereafter have to the laying

Agreement shall be effective service of process for any action, suit or proceeding in a Designated Court with respect to any matters
to which the parties have submitted to jurisdiction as set forth above.

 

q.
This Subscription Agreement may only be enforced against, and any claim, action, suit or other legal proceeding based upon, arising out
of, or related to this Subscription Agreement, or the negotiation, execution or performance of this Subscription Agreement, may only
be brought against the entities that are expressly named as parties hereto and then only with respect to the specific obligations set
forth herein with respect to such party. No past, present or future director, officer, employee, incorporator, manager, member, partner,
stockholder, affiliate, agent, attorney or other representative of any party hereto or of any affiliate of any party hereto, or any of
their successors or permitted assigns, shall have any liability for any obligations or liabilities of any party hereto under this Subscription
Agreement or for any claim, action, suit or other legal proceeding based on, in respect of or by reason of the transactions contemplated

r.
The Company shall, by 9:00 a.m., New York City time, on the first (1st) Business Day immediately following the date of this Subscription
Agreement, issue one or more press releases or file with the Commission a Current Report on Form 8-K (collectively, the “Disclosure
Document
”) disclosing, to the extent not previously publicly disclosed, all material terms of the transactions contemplated
hereby (and by the Other Subscription Agreements), the Transaction and any other material, nonpublic information that the Company has
provided to Subscriber at any time prior to the filing of the Disclosure Document. From and after the issuance of the Disclosure Document,
Subscriber shall not be in possession of any material, non-public information received from the Company, Heliogen or any of their respective
officers, directors or employees or the Placement Agent, as applicable, and the Subscriber shall no longer be subject to any confidentiality
or similar obligations under any current agreement, whether written or oral, with the Company, Heliogen or any of their respective affiliates,
relating to the transactions contemplated hereby. Notwithstanding the foregoing, without the prior written consent (including by e-mail)
of Subscriber, the Company shall not publicly disclose the name of Subscriber or investment advisor of Subscriber or any of their affiliates,
or include the name of Subscriber or investment advisor of Subscriber or any of their affiliates (i) in any press release or marketing
materials or (ii) in any filing with the Commission or any regulatory agency or trading market except as required by the federal securities
laws, rules or regulations and to the extent such disclosure is required by other laws, rules or regulations, at the request of the staff
of the Commission or regulatory agency or under NYSE regulations, in which case the Company shall provide Subscriber with prior written
notice (including by e-mail) and a copy of such permitted disclosure under this clause (ii), and shall reasonably consult with Subscriber
regarding such disclosure and shall include such revisions to such proposed disclosure as Subscriber shall reasonably request. Subscriber
will promptly provide any information reasonably requested by the Company that is necessary for any regulatory application or filing
required in connection with the Transaction (including filings with the Commission) to the extent reasonably available and, if such information
is not already public, the Company agrees to keep such information confidential and disclose only such information as is required with
respect to such filings.

 

s.
The obligations of Subscriber under this Subscription Agreement are several and not joint with the obligations of any Other Subscriber
or any other investor under the Other Subscription Agreements, and Subscriber shall not be responsible in any way for the performance
of the obligations of any Other Subscriber under this Subscription Agreement or any other investor under the Other Subscription Agreements.
The decision of Subscriber to purchase Subscribed Shares pursuant to this Subscription Agreement has been made by Subscriber independently
of any Other Subscriber or any other investor and independently of any information, materials, statements or opinions as to the business,
affairs, operations, assets, properties, liabilities, results of operations, condition (financial or otherwise) or prospects of the Company
or any of its subsidiaries which may have been made or given by any Other Subscriber or investor or by any agent or employee of any Other
Subscriber or investor, and neither Subscriber nor any of its agents or employees shall have any liability to any Other Subscriber or
investor (or any other person) relating to or arising from any such information, materials, statements or opinions. Nothing contained
herein or in any Other Subscription Agreement, and no action taken by Subscriber or investor pursuant hereto or thereto, shall be deemed
to constitute the Subscriber and other investors as a partnership, an association, a joint venture or any other kind of entity, or create
a presumption that the Subscriber and other investors are in any way acting in concert or as a group with respect to such obligations
or the transactions contemplated by the this Subscription Agreement and the Other Subscription Agreements. Subscriber acknowledges that
no Other Subscriber has acted as agent for the Subscriber in connection with making its investment hereunder and no Other Subscriber

Athena
Technology Acquisition Corp. Announces
Business Combination with Heliogen, Inc., a Leading Provider of AI-Enabled Concentrated Solar Energy; Combined Company Expected to Be
Listed

on
New York Stock Exchange

 

Transaction expected to accelerate and advance Heliogen’s mission to empower a sustainable future with low-cost, dispatchable concentrated solar energy as an affordable alternative to fossil fuels
Transaction implies pro forma enterprise value of the combined company of $2 billion and is estimated to provide gross proceeds at closing of up to approximately $415 million to the combined company, including estimated proceeds from a $165 million fully-committed Class A common stock PIPE, anchored by existing and new investors including funds and accounts managed by Counterpoint Global (Morgan Stanley), Salient Partners, Saba Capital, and the XCarb Innovation Fund of ArcelorMittal
Proceeds expected to be used to scale heliostat manufacturing, to support research and development efforts on next generation heliostat technology, to support global project development, and to fund the balance sheet
Heliogen’s closed loop, AI-enabled technology is commencing commercialization with internationally recognized customers in the industrial, mining, and energy sectors
Combination with all women-led Athena Technologies Acquisition Corp., pairs Heliogen’s company mission to revolutionize the energy industry with Athena’s emphasis on disruptive technology in complementary partnership

 

KENNESAW,
GA & PASADENA, CA, July 7, 2021 – Athena Technology Acquisition Corp. (“Athena”) (NYSE: ATHN), a special purpose
acquisition company (SPAC), and Heliogen, Inc. (“Heliogen” or the “Company”), a leading provider of AI-enabled
concentrated solar power, today announced that they have entered into a definitive agreement for a business combination. Following the
business combination, Athena expects to be renamed “Heliogen, Inc.” and will remain listed on the New York Stock Exchange
under the new ticker symbol “HLGN”.

 

Heliogen’s
modular, AI-enabled, concentrated solar power plants have the potential to revolutionize the energy market by alleviating intermittency
issues associated with renewable sources of power generation. Heliogen’s technology is designed to flatten the power generation
curve by using concentrated solar power with storage to increase the availability of energy to industry. The Company’s proprietary
heliostat layout and control system facilitate concentration of the sun’s rays and has the ability to generate temperatures at
the point of focus that can exceed 1,000 degrees centigrade. This heat can then be captured and converted for industrial use, power generation,
or to produce green hydrogen fuel, with the goal of providing near-24 hour renewable energy that could replace fossil fuels with concentrated
sunlight. Heliogen is commencing the commercialization of its AI-enabled, concentrated solar power modules with internationally recognized
customers in the industrial, mining, and energy sectors.

 

Athena,
led by Chairwoman Isabelle Freidheim and CEO Phyllis Newhouse, is one of the only entirely women-led SPACs, with a diverse, all-female
team of managers, advisors and investors. Athena’s mission-driven management team combines extensive investment and operational
expertise with a history of founding and scaling companies to positions of industry leadership. Through the Heliogen combination, Athena
Chief Executive Officer Phyllis Newhouse is believed to be the first woman of color in the U.S. to take a company public through a SPAC.

 

 

Heliogen’s
leadership will remain intact immediately after closing, with Bill Gross continuing as
Chief Executive Officer of the combined company. Mr. Gross will work alongside Heliogen’s current executive team, including veterans
of SpaceX, McKinsey & Company, Bechtel, Idealab, Deutsche Bank, and NRG Energy. Phyllis Newhouse is anticipated to join the Board
of Directors of the combined company, which will include representation from both Heliogen and Athena.

 

“We
are excited to combine with Athena to leverage our collective expertise as we execute our strategy to accelerate Heliogen’s growth
and scale our groundbreaking concentrated solar technology for the global energy market,” said Bill Gross, Founder and Chief Executive
Officer of Heliogen. “I have been building companies nearly my entire life, and the opportunity that Heliogen’s technology
represents, to decarbonize power generation, replace other carbon-intensive sources of industrial heat, and contribute to the cost efficient
production of alternative fuels such as green hydrogen, is at the head of the pack in terms of its potential to make a positive impact
on society. As economies and industries worldwide continue to decarbonize, I believe Heliogen’s AI-enabled technology will play
an important role in supporting and making those goals reality.”

 

“We
very much look forward to working with Bill and the entire team at Heliogen in the pursuit of a cleaner, decarbonized world,” said
Phyllis Newhouse, Chief Executive Officer of Athena. “Chairwoman Isabelle Freidheim and I co-founded Athena with a mission to work
with disruptive technology companies with the potential to advance industry, and even society, through innovation. Heliogen absolutely
meets that standard, not only in terms of solar-power generation, but in its ability to produce other sources of clean energy that may
replace fossil fuels. The company’s pioneering use of AI and its scalable approach to project development are exciting innovations,
and we couldn’t be more proud to combine with Heliogen as a publicly traded company.”

 

Transaction
Overview

 

The
business combination is structured as a statutory merger of Athena and Heliogen, with Heliogen surviving the merger as a wholly owned
subsidiary of Athena. All of Heliogen’s stockholders are expected to rollover their equity into the combined company and to receive
shares of Athena Class A common stock at closing as consideration.

 

The
transaction is anticipated to generate gross proceeds of up to approximately $415 million of cash, assuming no redemptions by Athena’s
public stockholders. The proceeds are expected to be used to scale heliostat manufacturing, to support research and development efforts
on next generation heliostat technology, to support global project development, and to fund the balance sheet. These gross proceeds include
investor commitments to purchase up to $165 million in shares of stock in Athena at $10.00 per share through a private investment in
public equity (a “PIPE”), subject to satisfaction of customary closing conditions. Assuming no redemptions by Athena’s
public stockholders and including anticipated proceeds from the PIPE, Athena estimates an initial pro forma implied enterprise value
of the combined company immediately after closing of the business combination of approximately $2.0 billion.

 

The
transaction has been unanimously approved by the boards of Heliogen and Athena. Completion of the proposed transaction is subject to
customary closing conditions, including the approval of Athena’s and Heliogen’s respective stockholders and regulatory approvals,
and is expected to occur in the fourth calendar quarter of 2021.

Use of Projections and Description of Key Relationships The Pack contains projected financial information with respect to the Company, namely revenue and the non – GAAP financial measures, E BITDA and Free Cash Flow for 2021 – 2026. Such projected financial information constitutes forward – looking information, and is for illustrative purposes only and should not be relied upon as necessarily being indicative of future results.

Disclaimer 2 The Pack contains descriptions of certain key business relationships of the Company. These descriptions are based on the Comp any ’s management team’s discussions with such counterparties and the latest available information and estimates as of the date o f the Pack. In certain cases, such descriptions are subject to negotiation and execution of definitive agreements with such cou nte rparties which have not been completed as of the date of the Pack and, as a result, such descriptions of key business relatio nsh ips of the Company, remain subject to change Financial Information; Non – GAAP Financial Measures The financial information and data contained in the Pack is unaudited and does not conform to Regulation S – X. Some of the financ ial information and data contained in the Pack, such as EBITDA and Free Cash Flow, have not been prepared in accordance with United States generally accepted accounting principles (“GAAP”). EBITDA is defined as net earnings (loss) before interest exp ens e, income tax expense (benefit) depreciation and amortization Free cash flow is defined as net income, plus depreciation and amortization, less capital expenditures (incl. acquisitions) and less change in net working capital. The Company believes the se non – GAAP measures of financial results provide useful information to management and investors regarding certain financial and business trends relating to the Company’s financial condition and results of operations. The Company believes that the use of th ese non – GAAP financial measures provides an additional tool for investors to use in evaluating projected operating results and t rends in and in comparing the Company’s financial measures with other similar companies, many of which present similar non – GAAP financ ial measures to investors. Management does not consider these non – GAAP measures in isolation or as an alternative to financial measures determined in accordance with GAAP. The principal limitation of these non – GAAP financial measures is that the y exclude significant expenses and income that are required by GAAP to be recorded in the Company’s financial statements. In addition, they are subject to inherent limitations as they reflect the exercise of judgments by management about which expens e a nd income are excluded or included in determining these non – GAAP financial measures. In order to compensate for these limitation s, management presents non – GAAP financial measures in connection with GAAP results. Please refer to the Appendix for a reconciliati on of the Company’s projected EBITDA and free cash flow for full years 2021 – 2026 to the most directly comparable measure prepared in accordance with GAAP because the Company is unable to provide this reconciliation without unreasonable effort due to the uncertainty and inherent difficulty of predicting the occurrence, the financial impact, and the periods in which the adju st ments may be recognized.. In addition, all the Company historical financial information included herein is preliminary and subject to change pending fi nal ization of the 2020 audit of the Company in accordance with PCAOB auditing standards. Trademarks The Pack contains trademarks, service marks, trade names and copyrights of the Company and other companies, which are the pro per ty of their respective owners.

Bill Gross
– CEO, Heliogen

Thank you operator, and thank you to everyone
listening this morning.

Our mission at Heliogen is to replace fossil fuels
with concentrated sunshine by making concentrated solar energy more efficient, affordable – and nearly always available. We believe
there’s a huge market opportunity right now in this energy transition to do that. In pursuing this mission, we’re honored
and excited to be working with Athena Technology Acquisition Corp. and believe this transaction will allow us to scale our technology
and make a significant impact on the world. I was thrilled when I first met Phyllis Newhouse, Athena’s CEO, as we are both driven
by making a positive difference in society. The team that Phyllis has put together is talented and experienced, and shares our same vision.
Phyllis, let me turn it over to you for a moment just to talk about how we view this opportunity together, and then I’ll go into
the technical presentation.

Phyllis
Newhouse – CEO, Athena Technology Acquisition Corp.

Thanks Bill. We are incredibly excited to be
working with you and Heliogen, and to make our shared vision of reliable concentrated solar energy a reality. Athena is a woman-led SPAC,
drawing on expertise from business founders, operators, venture capitalists, private equity partners, and former investment bankers.
So when we looked at doing a combination with a company, it was really about purpose, about a founder with passion, and from the
moment that I had the opportunity to talk with Bill, I knew that Heliogen was the company we wanted to do a deal with.

Through several rounds of due diligence, our
team looked at the technology behind Heliogen, we looked at their operations and market for growth, the management experience and
expertise, and we discussed their level of public market readiness. We brought in two technical due diligence firms. We brought
in Ernst & Young, EY, to do the financial due diligence and really stress test the assumptions in Heliogen’s projections and
their model. The Athena team visited Heliogen facilities, and took our time to get to know the business deeply. We were impressed by
what we found in all regards, and believe Heliogen is truly a disruptive company, one that can contribute to decarbonization of
economies and societies worldwide. So we’re excited to announce this business combination, and now, Bill, I’ll turn it
back over to you to discuss the company and technologies – Thank you.

Bill Gross
– CEO, Heliogen

Thanks Phyllis.

Heliogen is a concentrated solar company, which
means that we take the sun’s rays and redirect them, using mirrors, to focus one spot on a tower. That process has the ability
to generate temperatures that can exceed 1,000 degrees centigrade. That heat can then be used for several applications, including the
generation of clean power, industrial heat, and green fuels such as hydrogen. Although the process of concentrating sunlight is not new,
Heliogen has developed innovations which we believe fundamentally improve its potential.

Heliogen’s innovation focuses on refining
that process to improve the output and to solve the largest problem confronted by renewable sources of energy: intermittency.

First, Heliogen has invented a new way to
utilize artificial intelligence to make a large field of mirrors act as an enormous, precise magnifying glass to achieve very high
temperatures. Other people have built mirrors before, and other people have done concentrated solar before, but no one has ever
combined AI and software to make those mirrors both less expensive and to focus more accurately and achieve such high efficiencies.
Our proprietary technology allows for automatic adjustment of the mirrors at all times of day, enabling optimal concentration, which is
what enables us to generate ultra-high temperatures. This is what we call a closed-loop tracking system.

Second, we have a unique modular system
design that utilizes small mirrors, which will be manufactured at scale in a highly repeatable process. We will use these to build
one 5 megawatt module, and replicate it with each additional module generating another 5 megawatts. By building modularity, we can
build essentially the same thing over and over again, which is expected to reduce overall costs. And we’re the first company
in concentrated solar that we know of to develop a modular system like that.

We have a strong portfolio of patents covering
key aspects of our plant and process, including our closed-loop tracking system which is the linchpin of our solution. We have six patents
already granted and 13 patents pending on the technology. Why is this so important? This technology can be a game changer for many of
our customers. We want to scale this in a very large way and down the road we may license this technology to others – but it is
not currently baked into our forecasts.

Lastly, and most importantly, we believe Heliogen’s
technology will solve the intermittency issues that have plagued most other renewable sources.

Intermittency has been the bane of renewable
energy because if you can’t depend on it, you can’t produce power at peak times you need on the grid, you can’t
power industry which runs 24 hours a day, and you can’t produce reliable, low-cost, green hydrogen. So our technology will
allow those things to happen. Heliogen’s technology is designed to store the energy generated from concentrating the
sun’s rays into solid media – either rocks, sand or ceramic material – in the form of heat. This is a lower cost
form of storage than what other solar energy companies have used, and it will be made possible by the high temperatures enabled by
Heliogen’s technology. We will store that energy, and then when it is needed, use a heat exchanger to bring that energy either
to an engine, or to a manufacturing facility, or to an electrolyzer to make green hydrogen. Every electron you generate, you have to
use. So if you have extra electrons at noon, it’s just as bad as not having enough. Right now, in fact, there’s a lot of
curtailment of solar photovoltaic power in the Southwest United States, and all the hot regions where they put in a lot of solar
panels, because they need more power at seven in the evening, but they have too much at noon. We believe our technology will solve
that.

So, Heliogen’s technology will really provide
flexibility. It is flexible in scale, it is flexible in application, and it is flexible in time of use. Talking like that, it starts to
sound like an ideal source of energy. But, importantly, that didn’t occur overnight – Heliogen’s team has spent 8 years
improving all aspects of our technology with the goal of achieving the record temperatures from concentrated sunlight that we have
described. From the mirrors, to the sunlight receivers, to the full systems themselves, we are now on the fourth generation of technology
innovation, and we will continue to innovate.

This innovative spirit is one element, aside from
our technology, that has attracted our clients to us. We are currently working with ArcelorMittal, the largest steel manufacturer in North
America, South America and Europe; Rio Tinto, one of the largest mining and metals companies in the world, with operations in 35 countries;
and we have recently been selected by the US Department of Energy for an award to develop, build and operate a thermal storage test facility
supplied by concentrated sunlight. Our technology has wide application, and large energy companies and government agencies are recognizing
that.

So the technology is exciting, and
it’s the main story – our mission to create large scale renewable energy generation that is designed to solve
intermittency and produces zero carbon emissions. To go into more of the details around our financials and the transaction with
Athena, which we are also very excited about, I now want to turn to Heliogen’s CFO, Christie Obiaya.

Christie
Obiaya – CFO, Heliogen

Thank you, Bill.

First, I’d like to tell you about the other
aspects that we believe make Heliogen such a compelling opportunity.

The market in renewable energy and more broadly
across the energy transition space is incredibly strong. Global analysts consulting firms such as McKinsey predict that renewable
power capex spend of approximately $8.5 trillion will be required from 2020 to 2030 in order to achieve the carbon emissions reductions
that would support the 1.5 degree global warming target established by the Paris Agreements. As we plan to also provide solutions for
hydrogen production and industrial heat, Heliogen’s total addressable market is even larger.

This macroeconomic view is corroborated by the
level of inbound engagement that our team has had with prospective customers. Our potential sales pipeline is extremely diverse, and ranges
from global oil and gas companies, to mining and metals companies, to steel and cement industrial players. Geographically we are focused
initially on the US, but as you might expect, there’s huge opportunity worldwide especially in locations with strong solar resource
such as Mexico, South America, Australia, and Africa.

So how do we make money in this landscape?
In the near to medium term, we expect two primary sources of revenue. The first source is our delivery of complete Heliogen energy
plants to long term owner-operators, and we are hiring EPC contractors to do the installation of Heliogen’s technology. And
the second is from the sale of Heliogen’s heliostats onto projects that we develop on behalf of the energy plant
owner-operators. In the long term, we expect to use more of a licensing type model, in which we license our patent-protected
technology and heliostats to owner-operators and EPC companies. This model will result in lower revenue per module but a stronger
profit margin, and it’s not built into our financial forecast and therefore represents potential upside.

We forecast revenue to grow from about $8 million
in 2021 to nearly $200 million in 2023. That revenue will derive from our deploying three new projects with one module each. These three
projects are currently in various stages of development and contract negotiation. As the business scales, we expect that in 2026 our topline
revenue will grow to $2.4 billion, and we expect 2026 EBITDA over $800 million. Along with that growth, Heliogen sees a path to positive
EBITDA and positive free cash flow in 2025. It’s important to note that our revenue will come from deploying our technology rather
than from selling energy commodities, as we do not intend to be an owner-operator of energy facilities. So that will help us pursue a
relatively asset-light approach to generating profit. In addition, we are fortunate to have no debt, and we have been deliberate about
that choice in our trajectory thus far.

Now let me provide a brief overview of the proposed
business combination. The deal is based on a company valuation of $2 billion, implying a revenue multiple of 0.8x our 2026 forecast
revenue of $2.4 billion.

Proceeds from the transaction will be
used to fund heliostat manufacturing, to maintain our competitive edge through research and development, to support global project
development and execution, and to strengthen the balance sheet. Heliogen’s existing shareholders will roll over 100% of their
equity. The combined company will be listed on the New York Stock Exchange under the ticker HLGN, and we expect the merger to close
in early Q4 2021.

We are in an increasingly supportive environment
for Heliogen’s technology, and we are incredibly excited about the potential Heliogen has to transform the world’s energy
production landscape.

With that, I’d like to turn things back
to Bill.

Bill Gross
– CEO, Heliogen

Thanks Christie.

As I said at the outset, Heliogen is excited to
announce this transaction, and to be working with an incredible partner in Athena to bring Heliogen’s AI-enabled concentrated solar
technology to as diverse a set of applications and as wide a market as possible.

What we are developing at Heliogen – a completely
renewable, emissions-free source of dispatchable energy that is enabled by artificial intelligence – could be truly game-changing.
We expect it to address the key challenges of traditional renewable energy sources, while adding to the list of positives. At the end
of the day, we also expect the business built on this technology to be sustainable, scalable and profitable.

Thank you to everyone for listening, and for your
interest in Heliogen. Operator, you may now disconnect.

Concentrated Solar Power Firm Heliogen to Go Public in $2 Billion
SPAC Merger

Heliogen is combining with the SPAC Athena Technology, one of the few
so-called blank-check companies led by women

Heliogen says the intense heat from its solar operations can be collected
and processed to generate electricity, power industrial processes or produce hydrogen fuel—even when the sun goes down.

Heliogen Inc. is merging with a special-purpose acquisition company
to go public in a combination that values the concentrated solar power company at about $2 billion, the companies said.

Founded in 2013, Heliogen uses mirrors that are positioned with artificial
intelligence to reflect sunlight at a small receiver, generating an intense heat. That sunlight can be collected and processed to generate
electricity even when the sun goes down, the company says. The renewable energy can also be used to power industrial processes needed
to make materials like steel and to produce hydrogen fuel.

The company’s CEO is angel investor and entrepreneur Bill Gross
—sometimes confused with the bond investor Bill Gross, who co-founded investment giant Pacific Investment Management Co. Heliogen’s
Mr. Gross has made a fortune backing internet startups through his Idealab incubator and is now focusing on renewable energy companies.
The firm expects to install its first commercial project in 2023.

Heliogen is combining with the SPAC Athena Technology Acquisition Corp.,
one of the few so-called blank-check companies led by women. Cybersecurity executive and former U.S. Army officer Phyllis Newhouse and
venture capitalist Isabelle Freidheim are the SPAC’s CEO and board chair, respectively. Former Georgia Democratic gubernatorial
candidate Stacey Abrams is one of its advisers.

Based in Pasadena, Calif., Heliogen has been testing its technology
in a demonstration facility since 2019. It now hopes to scale operations to bring down costs and emissions in energy-intensive industries
like mining, Mr. Gross said in an interview.

“This allows us to be a defining solution for industrial decarbonization,”
he said. While commercial projects are expected to be much larger than the Heliogen test site, the company doesn’t anticipate needing
any new technology, Mr. Gross said.

The merger is the latest SPAC deal tied to renewable energy as companies
and investors line up trillions of dollars to fight climate change. Nearly 60 blank-check combinations have been announced since March
2020 that collectively value companies tied to electric cars, green energy or sustainability at some $145 billion, according to a Dow
Jones Market Data analysis of figures from SPAC Research.

Steelmaker ArcelorMittal SA is a Heliogen investor and is evaluating
uses of the company’s technology at its plants. Mining giant Rio Tinto PLC is also looking at working with Heliogen at a mine in
California.

Backed by investors including Microsoft Corp. co-founder Bill Gates
and billionaire biotech investor and Los Angeles Times owner Patrick Soon-Shiong, Heliogen was awarded $39 million by the U.S. Energy
Department late last year to advance its technology.

The company is expected to generate about $415 million in cash proceeds
through the SPAC deal. That includes the money held by the SPAC and a $165 million private investment in public equity, or PIPE, associated
with the merger. PIPE investors include ArcelorMittal and Morgan Stanley’s Counterpoint Global.

Private companies are flooding to special-purpose acquisition companies,
or SPACs, to bypass the traditional IPO process and gain a public listing. WSJ explains why some critics say investing in these so-called
blank-check companies isn’t worth the risk. Illustration: Zoë Soriano/WSJ

A SPAC is a shell company that raises money and trades on a stock exchange
with the sole purpose of merging with a private company to take it public. The private company, typically a startup, then gets the SPAC’s
place in the stock market. Blank-check mergers have become a popular alternative to traditional initial public offerings in the past few
years, in part because companies can make projections about their business when merging with a SPAC.

SPAC executives say the deals are accelerating growth for companies
that could change the world. Skeptics caution that many of the startups could fail, sticking individual investors with losses while insiders
are protected through unique incentives granted to blank-check company creators.

Athena raised $250 million in March. Other blank-check companies led
by women include Queen’s Gambit Growth Capital—a SPAC that shares a name with an opening sequence in chess and a popular show
on Netflix —and several financial-technology focused SPACs led by Betsy Cohen. The investment firm Cohen & Co., which has backed
several of Ms. Cohen’s blank-check firms, is partnering with Athena. The SPAC team now plans to launch other blank-check companies.

Ms. Newhouse said the SPAC’s executives found Heliogen attractive
because of its potential impact on communities around the world.

“This is a game changer in this industry,” she said.
