 RE: Investment Agreement

 Ladies and Gentlemen: 
 This agreement (the
“Agreement”) is entered into on the date set forth above by and among [•], a [•] (the “Purchaser”), Home Plate Sponsor LLC, a limited liability company (the “Sponsor”), and Home Plate
Acquisition Corporation, a Delaware corporation (the “Company”). Pursuant to the terms hereof, the Sponsor hereby accepts the offer the Purchaser has made to purchase, in the aggregate, [•] shares of Class B common stock,
$0.0001 par value per share of the Company (the “Shares”). The Purchaser shall purchase the Shares from the Sponsor, all of which are subject to forfeiture by the Purchaser if: the Purchaser submits an indication of interest for
less than 9.9% in the Company’s initial public offering (“IPO”) of units (“Units”) of the Company; does not submit any indication of interest in the IPO of Units of the Company; or fails to remit in full the
purchase price for the Units allocated to the Purchaser in the IPO. Pursuant to the Company’s certificate of incorporation, as amended to the date hereof, upon the Company’s consummation of an initial business combination, shares of
Class B common stock (including the Shares) will convert into shares of Class A common stock on a one-for-one basis, subject to adjustment, upon the terms and
conditions sets forth in such document. The Company’s, the Sponsor’s and the Purchaser’s agreements regarding such Shares are as follows: 

1. Purchase of Securities. 
 1.1
Purchase of Shares. For the sum of $[•] (the “Purchase Price”), which the Sponsor acknowledges receiving by wire transfer of immediately available funds, the Sponsor hereby agrees to transfer the Shares to the Purchaser,
and the Purchaser hereby purchases the Shares from the Sponsor, subject to forfeiture, on the terms and subject to the conditions set forth in this Agreement. The Company shall effect delivery of the Shares in book-entry form at the consummation of
the IPO. 
 2. Representations, Warranties and Agreements. 

2.1 Purchaser’s Representations, Warranties and Agreements. To induce the Sponsor to sell the Shares to the
Purchaser, the Purchaser hereby represents and warrants to the Sponsor and the Company and agrees with the Sponsor and the Company as follows: 

2.1.1 No Government Recommendation or Approval. The Purchaser understands that no federal or state agency has passed upon or made any
recommendation or endorsement of the offering of the Shares. 
 2.1.2 No Conflicts. The execution, delivery and performance of this
Agreement and the consummation by the Purchaser of the transactions contemplated hereby do not violate, conflict with or constitute a default under (i) the formation and governing documents of the Purchaser, (ii) any agreement, indenture
or instrument to which the Purchaser is a party or (iii) any law, statute, rule or regulation to which the Purchaser is subject, or any agreement, order, judgment or decree to which the Purchaser is subject. 













 2.1.3 Organization and Authority. The Purchaser is duly organized, validly existing
and in good standing under the laws of its jurisdiction of formation and possesses all requisite power and authority necessary to enter into this Agreement and to carry out the transactions contemplated by this Agreement. Upon execution and delivery
by the Purchaser and the other parties hereto, this Agreement will be a legal, valid and binding agreement of the Purchaser, enforceable against the Purchaser in accordance with its terms, except as such enforceability may be limited by applicable
bankruptcy, insolvency, fraudulent conveyance or similar laws affecting the enforcement of creditors’ rights generally and subject to general principles of equity (regardless of whether enforcement is sought in a proceeding at law or in
equity). 
 2.1.4 Experience, Financial Capability and Suitability. The Purchaser is: (i) sophisticated in financial matters and
is able to evaluate the risks and benefits of the investment in the Shares and (ii) able to bear the economic risk of its investment in the Shares for an indefinite period of time because the Shares have not been registered under the Securities
Act (as defined below) and therefore cannot be sold unless subsequently registered under the Securities Act or an exemption from such registration is available. The Purchaser is capable of evaluating the merits and risks of its investment in the
Company and has the capacity to protect its own interests. The Purchaser must bear the economic risk of this investment until the Shares are sold pursuant to: (x) an effective registration statement under the Securities Act or (y) an
exemption from registration available with respect to such sale. The Purchaser understands that the purchase of the Shares involves a high degree of risk which could cause the Purchaser to lose all or part of its investment. The Purchaser is able to
afford a complete loss of the Purchaser’s investment in the Shares. 
 2.1.5 Access to Information; Independent Investigation.
Prior to the execution of this Agreement, the Purchaser has had the opportunity to ask questions of and receive answers from representatives of the Company concerning an investment in the Company, as well as the finances, operations, business and
prospects of the Company, and the opportunity to obtain additional information to verify the accuracy of all information so obtained. In determining whether to make this investment, the Purchaser has relied solely on the Purchaser’s own
knowledge and understanding of the Company and its business based upon the Purchaser’s own due diligence investigation and the information furnished pursuant to this paragraph or as described in this paragraph. The Purchaser understands that no
person has been authorized to give any information or to make any representations which were not furnished pursuant to or as described in this Section 2 and the Purchaser has not relied on any other representations or information in making its
investment decision, whether written or oral, relating to the Company, its operations and/or its prospects. 
 2.1.6 Accredited
Investor. The Purchaser represents that it is an “accredited investor” as such term is defined in Rule 501(a) of Regulation D under the Securities Act of 1933, as amended (the “Securities Act”) and acknowledges the
sale contemplated hereby is being made, in reliance on a private placement exemption under the Securities Act, only to persons who are “accredited investors” within the meaning of Rule 501(a) of Regulation D under the Securities Act or
similar exemptions under state law. No “Bad Actor” disqualifying event described in Rule 506(d)(1)(i) to (viii) of the Securities Act is applicable to the Purchaser or any of its Rule 506(d) Related Parties. For purposes of this
Agreement, “Rule 506(d) Related Party” shall mean a Person that is a beneficial owner of such Purchaser’s securities for purposes of Rule 506(d) of the Securities Act. 

2.1.7 Investment Purposes. The Purchaser is purchasing the Shares solely for investment purposes, for the Purchaser’s own account
and not for the account or benefit of any other person, and not with a view towards the distribution or dissemination thereof. The Purchaser did not decide to enter into this Agreement as a result of any general solicitation or general advertising
within the meaning of Rule 502 under the Securities Act. Neither the Purchaser, nor any of its officers, directors, employees, agents, stockholders or partners has either directly or indirectly, including, through a broker or finder engaged in
any general solicitation, or published any advertisement in connection with the offer and sale of the Shares.

 2.1.8 Restrictions on Transfer; Shell Company. The Purchaser understands the Shares
are being offered in a transaction not involving a public offering within the meaning of the Securities Act. The Purchaser understands the Shares will be “restricted securities” within the meaning of Rule 144(a)(3) under the Securities
Act, and the Purchaser understands that the certificates or book-entries representing the Shares will contain a legend in respect of such restrictions. If in the future the Purchaser decides to offer, resell, pledge or otherwise transfer the Shares,
such Shares may be offered, resold, pledged or otherwise transferred only pursuant to: (i) registration under the Securities Act, or (ii) an available exemption from registration. The Purchaser agrees that if any transfer of its Shares or
any interest therein is proposed to be made, as a condition precedent to any such transfer, the Purchaser may be required to deliver to the Company an opinion of counsel satisfactory to the Company. Absent registration under the Securities Act or an
exemption therefrom, the Purchaser agrees not to resell the Shares. The Purchaser further acknowledges that because the Company is a shell company, Rule 144 may not be available to the Purchaser for the resale of the Shares until at least one year
following consummation of the initial business combination of the Company, despite technical compliance with the requirements of Rule 144 and the release or waiver of any contractual transfer restrictions. 

2.1.9 No Consents. No governmental, administrative or other third party consents or approvals are required, necessary or appropriate on
the part of the Purchaser in connection with the transactions contemplated by this Agreement. 
 2.1.10 Sanctions. The Purchaser is
not, and is not owned or controlled by or acting on behalf of a Sanctioned Person (as defined below). The Purchaser is not a non-U.S. shell bank or providing banking services to a non-U.S. shell bank. The Purchaser represents that if it is a financial institution subject to the Bank Secrecy Act (31 U.S.C. Section 5311 et seq.), as amended by the USA PATRIOT Act of 2001 and its
implementing regulations (collectively, the “BSA/PATRIOT Act”), that the Purchaser maintains, either directly or through the use of a third-party administrator, policies and procedures reasonably designed to comply with applicable
obligations under the BSA/PATRIOT Act. The Purchaser also represents that it maintains, either directly or through the use of a third party administrator, policies and procedures reasonably designed for the screening of any investors against
Sanctions-related lists of blocked or restricted persons. The Purchaser further represents and warrants that, to its best knowledge, the funds held by the Purchaser and used to purchase the Shares are derived from lawful activities. For purposes of
this Agreement, “Sanctioned Person” means, at any time, any person or entity: (i) listed on any Sanctions-related list of designated or blocked or restricted persons; (ii) that is a national of, the government of, or any
agency or instrumentality of the government of, or resident in, or organized under the laws of, a country or territory that is the target of comprehensive Sanctions from time to time (as of the date of this Agreement, Cuba, Iran, North Korea, Syria,
and the Crimea region); or (iii) owned or controlled by or acting on behalf of any of the foregoing. “Sanctions” means those trade, economic and financial sanctions laws, regulations, embargoes, and restrictive measures (in
each case having the force of law) administered, enacted or enforced from time to time by (a) the United States (including without limitation the U.S. Department of the Treasury, Office of Foreign Assets Control, the U.S. Department of State,
and the U.S. Department of Commerce), (b) the European Union and enforced by its member states, (c) the United Nations and (d) Her Majesty’s Treasury of the United Kingdom. 

2.1.11 CFIUS; Foreign Persons. The Purchaser is not a “foreign person” as such term is defined in 31 C.F.R. Part 800.224.

 2.1.12 ERISA. If the Purchaser is an employee benefit plan that is subject to Title I of the Employee Retirement Income Security
Act of 1974, as amended (“ERISA”), a plan, an individual retirement account or other arrangement that is subject to Section 4975 of the Internal Revenue Code of 1986, as amended (the “Code”) or an employee
benefit plan that is a governmental plan (as defined in Section 3(32) of ERISA), a church plan (as defined in Section 3(33) of ERISA), a non-U.S. plan (as described in Section 4(b)(4) of


  
 3 














 
ERISA) or other plan that is not subject to the foregoing but may be subject to provisions under any other federal, state, local, non-U.S. or other laws or
regulations that are similar to such provisions of ERISA or the Code, or an entity whose underlying assets are deemed to include “plan assets” of any such plan, account or arrangement (each, a “Plan”) subject to the
fiduciary or prohibited transactions provisions of ERISA or Section 4975 of the Code, the Purchaser represents and warrants that (i) neither the Company, nor any of its respective affiliates (the “Transactions Parties”)
has acted as the Plan’s fiduciary, or has been relied on for advice, with respect to its decision to acquire and hold the Shares, and none of the Transactions Parties shall at any time be relied upon as the Plan’s fiduciary with respect to
any decision to acquire, continue to hold or transfer the Shares and (ii) none of the acquisition, holding and/or transfer or disposition of the Shares will result in a non-exempt prohibited transaction
under ERISA or Section 4975 of the Code or a violation of any similar law or regulation. 
 2.1.13 Non Reliance. In making its
decision to make the investments contemplated hereby and to enter into this Agreement, the Purchaser represents that it has relied solely upon its own independent investigation. Without limiting the generality of the foregoing, the Purchaser has not
relied on any statements or other information provided, if any, by or on behalf of Jefferies LLC or any of its affiliates, control persons, officers, directors, employees, partners, agents or representatives of any of the foregoing concerning the
Company, the Sponsor, the Shares, this Agreement or the transactions contemplated hereby. The Purchaser acknowledges and agrees that Jefferies LLC (i) has not provided the Purchaser with any advice with respect to the Shares, this Agreement or

steps that they deem necessary or appropriate to protect their respective interests arising therefrom without regard to the consequences to the Purchaser, and that certain of these actions may have material and adverse consequences to the Purchaser.
The Purchaser acknowledges that it has not relied on Jefferies LLC in connection with its determination as to the legality of its acquisition of the Shares, of its entering into this Agreement or as to the other matters referred to herein and the
Purchaser has not relied on any investigation that Jefferies LLC or any of its affiliates or any person acting on its behalf may have conducted with respect to the Shares, the Company or the Sponsor. The Purchaser further acknowledges that it has
not relied on any information contained in any research reports prepared by Jefferies LLC or any of its affiliates.

 5. Restrictions on Transfer. 

5.1 Lock-up. The Purchaser agrees that it shall not Transfer (as defined below) any Shares (or
shares of Class A common stock issuable upon conversion thereof) until the earlier to occur of: (a) one year after the completion of the Company’s initial business combination; and (b) subsequent to the Company’s initial
business combination, (x) if the last reported sale price of the shares of Class A common stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock capitalizations, reorganizations, recapitalizations and the like) for
any 20 trading days within any 30-trading day period commencing at least 180 days after the Company’s initial business combination, or (y) the date on which the Company completes a liquidation, merger, capital stock exchange or other
similar transaction that results in all of the Company’s public stockholders having the right to exchange their shares of Class A common stock for cash, securities or other property (the
“Lock-up Period”). Notwithstanding the first sentence of this Section 5.1, Transfers of the Shares and shares of Class A common stock issued or issuable upon the exercise or
conversion of the Shares and that are held by the Purchaser or any of its permitted transferees (that have complied with this Section 5.1), are permitted (i) to the Company’s officers or directors, any affiliates or family members of
any of the Company’s officers or directors, any members of the Sponsor, or any affiliates of the Sponsor or any employees of such affiliates; (ii) in the case of an individual, by gift to a member of the individual’s immediate family
or to a trust, the beneficiary of which is a member of the individual’s immediate family or an affiliate of such person, or to a charitable organization; (iii) in the case of an individual, by virtue of laws of descent and distribution
upon death of the individual; (iv) in the case of an individual, pursuant to a qualified domestic relations order; (v) by private sales or transfers made in connection with the consummation of the Company’s initial business

business combination; and (ix) in the event of the Company’s liquidation, merger, stock exchange, reorganization or other similar transaction that results in all of the Company’s public stockholders having the right to exchange their
shares of Class A common stock for cash, securities or other property subsequent to the consummation of the Company’s initial business combination (the transferees referred to in clauses (i) through (ix) above are called
“Permitted Transferees”); provided, however, that in the case of clauses (i) through (vi), these Permitted Transferees must enter into a written agreement agreeing to be bound by the terms of this Agreement. For purposes of
clarity, any shares of Class A common stock purchased by the Purchaser in the IPO or aftermarket are not subject to the restrictions set forth in this Section 5. 

5.2 Transfer. As used in this Agreement, “Transfer” shall mean the (a) sale, transfer or assignment of, offer to
sell, contract or agreement to sell, hypothecate, pledge, grant of any option to purchase or otherwise dispose of or agreement to dispose of, directly or indirectly, or establishment or increase of a put equivalent position or liquidation with

Commission (the “SEC”) promulgated thereunder with respect to, any security, (b) entry into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any
security, whether any such transaction described in clauses (a) or (b) is to be settled by delivery of such securities, in cash or otherwise or (c) public announcement of any intention to effect any transaction specified in clause
(a) or (b). 
 5.3 Securities Law Restrictions. In addition to the restrictions in Section 5.1, the Purchaser agrees not to
sell, transfer, pledge, hypothecate or otherwise dispose of all or any part of the Shares unless, prior thereto (a) a registration statement on the appropriate form under the Securities Act with respect to the Shares proposed to be transferred
shall then be effective or (b) the Company has received an opinion from counsel reasonably satisfactory to the Company, that such registration is not required because such transaction is exempt from registration under the Securities Act and the
rules and regulations promulgated by the SEC thereunder and from all applicable state securities laws. Each register and book-entry for the Shares shall contain a notation, and each certificate (if any) representing the Shares shall have endorsed
thereon legends, substantially as follows: 

  
 7 














 “THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT
OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS AND NEITHER THE SECURITIES NOR ANY INTEREST THEREIN MAY BE OFFERED, SOLD, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT OR SUCH
LAWS OR AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT AND SUCH LAWS WHICH, IN THE OPINION OF COUNSEL (IF THE COMPANY SO REQUESTS), IS AVAILABLE.”

transaction affecting the Company’s outstanding Shares without receipt of consideration, any new, substituted or additional securities or other property which are by reason of such transaction distributed with respect to any Shares subject to

number and/or class of Shares subject to this Section 5 and Section 3. 
 5.5 Registration Rights. The Purchaser
acknowledges that the Shares are being purchased pursuant to an exemption from the registration requirements of the Securities Act and will become freely tradable only after certain conditions are met or they are registered pursuant to a
registration and stockholder rights agreement to be entered into prior to the closing of the IPO by and among the Company and certain other parties thereto, in substantially the form provided to the Purchaser prior to the date hereof (the
“Registration Rights Agreement”). The Purchaser shall be deemed to be a “Permitted Transferee” as defined in the Registration Rights Agreement, and an assignee of the Sponsor’s rights, duties and obligations under the
Registration Rights Agreement with respect to the Shares (if not forfeited). By entering into this Agreement, the Purchaser agrees to be bound by the terms and conditions of the Registration Rights Agreement. 

5.6 No Short Sales. The Purchaser hereby agrees that neither it, nor any person or entity acting on its behalf, will engage in any
Short Sales with respect to securities of the Company prior to the closing of an initial business combination. For purposes of this Section 5.6, “Short Sales” shall include, without limitation, all “short sales” as
defined in Rule 200 promulgated under Regulation SHO under the Exchange Act, and all types of direct and indirect stock pledges (other than pledges in the ordinary course of business as part of prime brokerage arrangements), forward sale contracts,

6.9 Severability. In the event that any court of competent jurisdiction shall determine that any provision, or any portion thereof,
contained in this Agreement shall be unreasonable or unenforceable in any respect, then such provision shall be deemed limited to the extent that such court deems it reasonable and enforceable, and as so limited shall remain in full force and
effect. In the event that such court shall deem any such provision, or portion thereof, wholly unenforceable, the remaining provisions of this Agreement shall nevertheless remain in full force and effect. 

6.10 No Waiver of Rights, Powers and Remedies. No failure or delay by a party hereto in exercising any right, power or remedy under
this Agreement, and no course of dealing among the parties hereto, shall operate as a waiver of any such right, power or remedy of such party. No single or partial exercise of any 

  
 9 














 
right, power or remedy under this Agreement by a party hereto, nor any abandonment or discontinuance of steps to enforce any such right, power or remedy, shall preclude such party from any other
or further exercise thereof or the exercise of any other right, power or remedy hereunder. The election of any remedy by a party hereto shall not constitute a waiver of the right of such party to pursue other available remedies. No notice to or
demand on a party not expressly required under this Agreement shall entitle the party or parties receiving such notice or demand to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of the
party giving such notice or demand to any other or further action in any circumstances without such notice or demand. 
 6.11 Survival of
Representations and Warranties. All representations and warranties made by the parties hereto in this Agreement or in any other agreement, certificate or instrument provided for or contemplated hereby, shall survive the execution and delivery
hereof, any investigations made by or on behalf of the parties and the consummation of the transactions contemplated by this Agreement. 

6.12 No Broker or Finder. Each of the parties hereto represents and warrants to the other parties that no broker, finder or other
financial consultant has acted on its behalf in connection with this Agreement or the transactions contemplated hereby in such a way as to create any liability on any of the other parties. Each of the parties hereto agrees to indemnify and save the
other parties harmless from any claim or demand for commission or other compensation by any broker, finder, financial consultant or similar agent claiming to have been employed by or on behalf of such party and to bear the cost of legal expenses
incurred in defending against any such claim. 
 6.13 Headings and Captions. The headings and captions of the various subdivisions of
this Agreement are for convenience of reference only and shall in no way modify or affect the meaning or construction of any of the terms or provisions hereof. 

6.14 Counterparts. This Agreement may be executed in one or more counterparts, all of which when taken together shall be considered one
and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other parties, it being understood that all parties need not sign the same counterpart. The words “execution”,
“signed”, “signature” and words of like import in this Agreement and the Registration Rights Agreement or in any certificate, agreement or document related to this Agreement and the Registration Rights Agreement shall include
images of manually executed signatures transmitted by facsimile or other electronic format (including, without limitation, “pdf”, “tif” or “jpg”) and other electronic signatures (including, without limitation, DocuSign
and AdobeSign). The use of electronic signatures and electronic records (including, without limitation, any contract or other record created, generated, sent, communicated, received, or stored by electronic means) shall be of the same legal effect,
validity and enforceability as a manually executed signature or use of a paper-based recordkeeping system to the fullest extent permitted by applicable law, including the U.S. Electronic Signatures in Global and National Commerce Act, the New York
State Electronic Signatures and Records Act and any other applicable law, including, without limitation, any state law based on the Uniform Electronic Transactions Act of the United States or the Uniform Commercial Code of the United States. 

6.15 Construction. The parties hereto have participated jointly in the negotiation and drafting of this Agreement. If an ambiguity or
question of intent or interpretation arises, this Agreement will be construed as if drafted jointly by the parties hereto and no presumption or burden of proof will arise favoring or disfavoring any party hereto because of the authorship of any
provision of this Agreement. The words “include,” “includes,” and “including” will be deemed to be followed by “without limitation.” Pronouns in masculine, feminine, and neuter
genders will be construed to include any other gender, and words in the singular form will be construed to include the plural and vice versa, unless the context otherwise requires. The words “this Agreement,”
“herein,” “hereof,” “hereby,” “hereunder,” and words of similar import refer 

  
 10 














 
to this Agreement as a whole and not to any particular subdivision unless expressly so limited. The parties hereto intend that each representation, warranty, and covenant contained herein will
have independent significance. If any party hereto has breached any representation, warranty, or covenant contained herein in any respect, the fact that there exists another representation, warranty or covenant relating to the same subject matter
(regardless of the relative levels of specificity) which such party hereto has not breached will not detract from or mitigate the fact that such party hereto is in breach of the first representation, warranty, or covenant. 

6.16 Jurisdiction. The parties hereby irrevocably and unconditionally (i) submit to the jurisdiction of the state courts of New
York and the United States District Court for the Southern District of New York for the purpose of any suit, action or other proceeding arising out of or based upon this Agreement, (ii) agree not to commence any suit, action or other proceeding
arising out of or based upon this Agreement except in state courts of New York or the United States District Court for the Southern District of New York, and (iii) waive, and agree not to assert, by way of motion, as a defense, or otherwise, in
any such suit, action or proceeding, any claim that it is not subject personally to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment or execution, that the suit, action or proceeding is brought in an
inconvenient forum, that the venue of the suit, action or proceeding is improper or that this Agreement or the subject matter hereof may not be enforced in or by such court. 

6.17 Waiver of Jury Trial. The parties hereto hereby waive any right to a jury trial in connection with any litigation pursuant to this
Agreement and the transactions contemplated hereby. 
 6.18 Expenses. Each of the Company, the Sponsor and the Purchaser will bear
its own costs and expenses incurred in connection with the preparation, execution and performance of this Agreement and the consummation of the transactions contemplated hereby, including all fees and expenses of agents, representatives, financial
advisors, legal counsel and accountants. The Company shall be responsible for the fees of its transfer agent, stamp taxes and all of The Depository Trust Company’s fees associated with the issuance of the Shares and the securities issuable upon
conversion of the Shares. 
 6.19 Specific Performance. Each party hereto agrees that irreparable damage may occur in the event any
provision of this Agreement was not performed by any of the other parties hereto in accordance with the terms hereof and that the such party shall be entitled to specific performance of the terms hereof, in addition to any other remedy at law or
equity. 
 6.20 Confidentiality. Except as may be required by law, regulation or applicable stock exchange listing requirements,
unless and until the transactions contemplated hereby and the terms hereof are publicly announced or otherwise publicly disclosed by the Company, the parties hereto shall keep confidential and shall not publicly disclose the existence or terms of
this Agreement. 
 7. Voting and Tender of Shares. The Purchaser agrees to vote the Shares in favor of an initial business combination that the
Company negotiates and submits for approval to the Company’s stockholders and shall not seek redemption with respect to any of such Shares. Additionally, the Purchaser agrees with the Company not to tender any Shares in connection with a tender
offer presented to the Company’s stockholders in connection with an initial business combination negotiated by the Company.  

8. Indemnification. Each party shall indemnify the other parties against any loss, cost or damages (including reasonable attorney’s fees and
expenses) incurred as a result of such party’s breach of any representation, warranty, covenant or agreement in this Agreement. 

  
 11 














 9. Use of Purchaser’s Name. Neither the Company nor the Sponsor will, without the
prior written consent of the Purchaser in each instance, use in advertising, publicity or otherwise the name of the Purchaser; however the Company may disclose the Purchaser’s name and information concerning the Purchaser (A) to the extent
required by law, regulation or regulatory request, including in the registration statement in connection with the IPO or (B) to the Company’s lawyers, independent accountants and to other advisors and service providers who reasonably
require the Purchaser’s information in connection with the provision of services to the Company and are advised of the confidential nature of such information. Any determination by the Company’s outside counsel that disclosure of the
Purchaser’s name and other information concerning the Purchaser is so required shall be final.
