 RE:
Representative Shares Subscription Agreement 
 Ladies and Gentlemen: 

This agreement (the “Agreement”) is entered into on ______________, 2021 by and between Kingswood Capital Markets, division
of Benchmark Investments, Inc. (the “Subscriber” or “you”), and Gladstone Acquisition Corporation, a Delaware corporation (the “Company”, “we” or “us”). Pursuant to
the terms hereof, the Company hereby accepts the offer the Subscriber has made to purchase 120,000 shares (the “Shares”) of Class A common stock, $0.0001 par value per share (the “Class A
Common Stock”). The Company and the Subscriber’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 Company acknowledges receiving in
cash, the Company hereby issues the Shares to the Subscriber, and the Subscriber hereby purchases the Shares from the Company, on the terms and subject to the conditions set forth in this Agreement. Concurrently with the Subscriber’s execution
of this Agreement, the Company shall, at its option, deliver to the Subscriber a certificate registered in the Subscriber’s name representing the shares (the “Original Certificate”), or effect such delivery in book-entry form.

 2. Representations, Warranties and Agreements. 

2.1. Subscriber’s Representations, Warranties and Agreements. To induce the Company to issue the Shares to the Subscriber, the
Subscriber hereby represents and warrants to the Company and agrees with the Company as follows: 
 2.1.1. No Government Recommendation or
Approval. The Subscriber 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 Subscriber of the
transactions contemplated hereby do not violate, conflict with or constitute a default under (i) the formation and governing documents of the Subscriber, (ii) any agreement, indenture or instrument to which the Subscriber is a party or
(iii) any law, statute, rule or regulation to which the Subscriber is subject, or any agreement, order, judgment or decree to which the Subscriber is subject. 

2.1.3. Organization and Authority. The Subscriber is in good standing under the laws of Delaware and possesses all requisite power and
authority necessary to carry out the transactions contemplated by this Agreement. Upon execution and delivery by you, this Agreement is a legal, valid and binding agreement of Subscriber, enforceable against Subscriber 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. Subscriber 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. Subscriber is capable of evaluating
the merits and risks of its investment in the Company and has the capacity to protect its own interests. Subscriber must bear the economic risk of this investment until the Shares are sold pursuant to: (i) an effective registration statement
under the Securities Act or (ii) an exemption from registration available with respect to such sale. Subscriber is able to bear the economic risks of an investment in the Shares and to afford a complete loss of Subscriber’s investment in
the Shares. 
 2.1.5. Access to Information; Independent Investigation. Prior to the execution of this Agreement, the Subscriber 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, Subscriber has relied solely on Subscriber’s own knowledge and understanding of the Company and its business based
upon Subscriber’s own due diligence investigation and the information furnished pursuant to this paragraph. Subscriber understands that no person has been authorized to give any information or to make any representations which were not
furnished pursuant to this Section 2 and Subscriber 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. Regulation D Offering. Subscriber represents that it is an “accredited investor” as such term is defined in Rule 501(a)
of Regulation D under the Securities Act of 1933, as amended (the “Securities Act”) and acknowledges the sale contemplated hereby is being made in reliance on a private placement exemption to “accredited investors” within
the meaning of Section 501(a) of Regulation D under the Securities Act or similar exemptions under state law. 
 2.1.7. Investment
Purposes. The Subscriber is purchasing the Shares solely for investment purposes, for the Subscriber’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 Subscriber 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. 

2.1.8. Restrictions on Transfer; Shell Company. Subscriber understands the Shares are being offered in a transaction not involving a
public offering within the meaning of the Securities Act. Subscriber understands the Shares will be “restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act, and Subscriber understands that the certificates or
book-entries representing the Shares will contain a legend in respect of such restrictions. If in the future the Subscriber 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. Subscriber 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, Subscriber may be required to deliver to the Company an opinion of counsel satisfactory to the Company. Absent registration or an exemption, the Subscriber agrees not to resell the Shares. Subscriber further
acknowledges that because the Company is a shell company, Rule 144 may not be available to the Subscriber for the resale of the Shares until 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 Governmental
Consents. No governmental, administrative or other third party consents or approvals are required, necessary or appropriate on the part of Subscriber in connection with the transactions contemplated by this Agreement. 

2.1.9. Bad Actor Status. No “bad actor” disqualifying event described in Rule 506(d)(1)(i)-(viii) of the Securities Act (a
“Disqualification Event”) is applicable to the Subscriber or, to the Subscriber’s knowledge, any Subscriber Covered Person, except for a Disqualification Event as to which Rule
506(d)(2)(ii-iv) or (d)(3), is applicable. The Subscriber represents that it has exercised reasonable care to determine the accuracy of the representation made by the Subscriber in this paragraph. 












 2.2. Company’s Representations, Warranties and Agreements. To induce the
Subscriber to purchase the Shares, the Company hereby represents and warrants to the Subscriber and agrees with the Subscriber as follows: 

2.2.1. Organization and Corporate Power. The Company is a Delaware corporation and is qualified to do business in every jurisdiction in
which the failure to so qualify would reasonably be expected to have a material adverse effect on the financial condition, operating results or assets of the Company. The Company possesses all requisite corporate power and authority necessary to
carry out the transactions contemplated by this Agreement. 
 2.2.2. No Conflicts. The execution, delivery and performance of this
Agreement and the consummation by the Company of the transactions contemplated hereby do not violate, conflict with or constitute a default under (i) the Certificate of Incorporation or By Laws of the Company, (ii) any agreement, indenture
or instrument to which the Company is a party or (iii) any law, statute, rule or regulation to which the Company is subject, or any agreement, order, judgment or decree to which the Company is subject. 

2.2.3. Title to Securities. Upon issuance in accordance with, and payment pursuant to, the terms hereof, the Shares will be duly and
validly issued, fully paid and nonassessable. Upon issuance in accordance with, and payment pursuant to, the terms hereof, the Subscriber will have or receive good title to the Shares, free and clear of all liens, claims and encumbrances of any
kind, other than (a) transfer restrictions hereunder and other agreements to which the Shares may be subject which have been notified to the Subscriber in writing, (b) transfer restrictions under federal and state securities laws, and
(c) liens, claims or encumbrances imposed due to the actions of the Subscriber. 
 2.2.4. No Adverse Actions. There are no
actions, suits, investigations or proceedings pending, threatened against or affecting the Company which: (i) seek to restrain, enjoin, prevent the consummation of or otherwise affect the transactions contemplated by this Agreement or
(ii) question the validity or legality of any transactions or seeks to recover damages or to obtain other relief in connection with any transactions. 

2.2.5 Authorization. The shares of Class A Common Stock issuable upon conversion of the Shares have been duly authorized and
reserved for issuance upon such conversion. 
 2.2.6 No General Solicitation. Neither the Company nor any of its affiliates or any
person or entity acting on its or their behalf has engaged directly or indirectly in any form of general solicitation or general advertising within the meaning of Rule 502 under the Securities Act in connection with the offering, issuance and sale
of the Shares. 
 3. Waiver of Liquidation Distributions; Redemption Rights. In connection with the Shares purchased pursuant to this Agreement, the
Subscriber hereby waives any and all right, title, interest or claim of any kind in or to any distributions by the Company from the trust account which will be established for the benefit of the Company’s public stockholders and into which
substantially all of the proceeds of the Company’s initial public offering (the “IPO”) will be deposited (the “Trust Account”), in the event of a liquidation of the Company upon the Company’s failure to
timely complete an initial business combination. For purposes of clarity, in the event the Subscriber purchases Shares in the IPO or in the aftermarket, any additional Shares so purchased shall be eligible to receive any liquidating distributions by
the Company. However, in no event will the Subscriber have the right to redeem any Shares into funds held in the Trust Account upon the successful completion of the Company’s initial acquisition, share exchange, share reconstruction and
amalgamation with, purchase of all or substantially all of the assets of, entry into contractual arrangements with, or engagement in any other similar business combination with one or more businesses or entities (“Business
Combination”). 
 4. Restrictions. 

4.1 Restrictions on Transfer. Subscriber 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 and applicable state securities laws 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 promulgated by the Securities and
Exchange Commission thereunder and with all applicable state securities 












 
laws. The undersigned also agrees by its acceptance of the Shares, that it will not: (a) sell, transfer, assign, pledge or hypothecate the Shares until the completion of the Company’s
initial Business Combination to anyone other than: (i) an underwriter or a selected dealer participating in the IPO, or (ii) an officer, partner, registered person, or affiliate of the undersigned or of any such underwriter or selected
dealer, in each case in accordance with FINRA Conduct Rule 5110(e)(1), and (b) cause the Shares to be the subject of any hedging, short sale, derivative, put or call transaction, until the completion of the Company’s initial Business
Combination, that would result in the effective economic disposition of the Shares, except as provided for in FINRA Rule 5110(e)(2). 
 4.2
Waiver. Subscriber, on behalf of itself and each of the Subscriber’s designees or permitted assignees, further agrees by its acceptance of the Shares (i) to waive its redemption rights (or right to participate in any tender offer)
with respect to the Shares in connection with the completion of the Business Combination and (ii) to waive its rights to liquidating distributions from the Trust Account in connection with its proposed IPO with respect to the Shares if the
Company fails to complete its initial Business Combination within 18 months from the closing date of the IPO (or such later date as may be approved by the Company’s stockholders). The Subscriber hereby further waives, with respect to any shares
of Common Stock held by it, him or her, if any, whether acquired now or hereafter, any redemption rights it, he or she may have in connection with the consummation of a Business Combination or amendments to the Company’s amended and restated
certificate of incorporation (the “Charter”) prior thereto, including, without limitation, any such rights available in the context of a stockholder vote to approve such Business Combination or a stockholder vote to approve an
amendment to the Charter to modify (i) (A) the substance or timing of the Company’s obligation to redeem 100% of the shares of Common Stock sold as part of the units sold by the Company in its IPO if the Company has not consummated a
Business Combination within the time period set forth in the Charter or (B) any other provisions relating to stockholders’ rights or pre-initial Business Combination activity or (ii) in the
context of a tender offer made by the Company to purchase shares of Common Stock (although the Subscriber shall be entitled to redemption and liquidation rights with respect to any Offering Shares it or they hold if the Company fails to consummate a
Business Combination within the time period set forth in the Charter). 
 4.3. Restrictive Legends. Any certificates representing the
Shares shall have endorsed thereon a legend substantially as follows: 
 “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, IS AVAILABLE.” 
 “THE
SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A LOCKUP AND MAY NOT BE OFFERED, SOLD, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED DURING THE TERM OF THE LOCKUP.” 

4.4. Additional Shares or Substituted Securities. In the event of the declaration of a share dividend, the declaration of an
extraordinary dividend payable in a form other than Shares, a spin-off, a share split, an adjustment in conversion ratio, a recapitalization or a similar 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 this Section 4 or into which such Shares thereby
become convertible shall immediately be subject to this Section 4. Appropriate adjustments to reflect the distribution of such securities or property shall be made to the number and/or class of Shares subject to this Section 4. 

4.5. Registration Rights. Subscriber 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 rights agreement to be entered into with the Company prior to the closing of the IPO (the
“Registration Rights Agreement”). 












 5. Other Agreements. 

5.1. Further Assurances. Subscriber agrees to execute such further instruments and to take such further action as may reasonably be
necessary to carry out the intent of this Agreement. 
 5.2. Notices. All notices, statements or other documents which are required or
contemplated by this Agreement shall be: (i) in writing and delivered personally or sent by first class registered or certified mail, overnight courier service or facsimile or electronic transmission to the address designated in writing,
(ii) by facsimile to the number most recently provided to such party or such other address or fax number as may be designated in writing by such party and (iii) by electronic mail, to the electronic mail address most recently provided to
such party or such other electronic mail address as may be designated in writing by such party. Any notice or other communication so transmitted shall be deemed to have been given on the day of delivery, if delivered personally, on the business day
following receipt of written confirmation, if sent by facsimile or electronic transmission, one (1) business day after delivery to an overnight courier service or five (5) days after mailing if sent by mail. 

5.3. Entire Agreement. This Agreement, together with the Registration Rights Agreement, each substantially in the form to be filed as an
exhibit to the Registration Statement on Form S-1 associated with the Company’s IPO, embodies the entire agreement and understanding between the Subscriber and the Company with respect to the subject
matter hereof and supersedes all prior oral or written agreements and understandings relating to the subject matter hereof. No statement, representation, warranty, covenant or agreement of any kind not expressly set forth in this Agreement shall
affect, or be used to interpret, change or restrict, the express terms and provisions of this Agreement. 
 5.4. Modifications and
Amendments. The terms and provisions of this Agreement may be modified or amended only by written agreement executed by all parties hereto. 

5.5. Waivers and Consents. The terms and provisions of this Agreement may be waived, or consent for the departure therefrom granted,
only by a written document executed by the party entitled to the benefits of such terms or provisions. No such waiver or consent shall be deemed to be or shall constitute a waiver or consent with respect to any other terms or provisions of this
Agreement, whether or not similar. Each such waiver or consent shall be effective only in the specific instance and for the purpose for which it was given, and shall not constitute a continuing waiver or consent. 

5.6. Assignment. The rights and obligations under this Agreement may not be assigned by either party hereto without the prior written
consent of the other party. 
 5.7. Benefit. All statements, representations, warranties, covenants and agreements in this Agreement
shall be binding on the parties hereto and shall inure to the benefit of the respective successors and permitted assigns of each party hereto. Nothing in this Agreement shall be construed to create any rights or obligations except among the parties
hereto, and no person or entity shall be regarded as a third-party beneficiary of this Agreement. 
 5.8. Governing Law. This
Agreement and the rights and obligations of the parties hereunder shall be construed in accordance with and governed by the laws of New York applicable to contracts wholly performed within the borders of such state, without giving effect to the
conflict of law principles thereof. 
 5.9. 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. 

5.10. 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 between 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 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 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. 

5.11. 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 and any investigations made by or on behalf of the parties. 

5.12. No Broker or Finder. Each of the parties hereto represents and warrants to the other 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 the other. Each of the parties hereto agrees to indemnify and save the other 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. 
 5.13. 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. 

5.14. 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 party, it being understood that both parties need not sign the same counterpart. In the event that any signature is
delivered by facsimile transmission or any other form of electronic delivery, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such
signature page were an original thereof. 
 5.15. 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 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. 
 5.16. Mutual Drafting. This Agreement is the
joint product of the Subscriber and the Company and each provision hereof has been subject to the mutual consultation, negotiation and agreement of such parties and shall not be construed for or against any party hereto. 

6. Voting and Tender of Shares. Subscriber 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 such Shares. Additionally, the Subscriber agrees 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. 
 7. Indemnification. Each party shall indemnify the other 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.
