(f)    Supply any necessary information or documents as may be requested by the Company (or its authorized agents) in

 (h)    Render to the Company monthly written statements of the
activities of, and amounts in, the Trust Account reflecting all receipts and disbursements of the Trust Account; 

(i)    Commence liquidation of the Trust Account only after and promptly after (x) receipt of, and only in accordance
with, the terms of a letter from the Company (“Termination Letter”) in a form substantially similar to that attached hereto as either Exhibit A or Exhibit B, as applicable, signed on behalf of the
Company by its Chief Executive Officer, President, Chief Financial Officer, Secretary or Chairman of the board of directors of the Company (the “Board”) or other authorized officer of the Company, and complete the liquidation

obligation owed by the Company as a result of assets of the Company or interest or other income earned on the Property, which amount shall be delivered directly to the Company by electronic funds transfer or other method of prompt payment, and the
Company shall forward such payment to the relevant taxing authority; provided, however, that to the extent there is not sufficient cash in the Trust Account to pay such tax obligation, the Trustee shall liquidate such assets held in
the Trust Account as shall be designated by the Company in writing to make such distribution so long as there is no reduction in the principal amount initially deposited in the Trust Account; provided, further, that if the tax to be
paid is a franchise tax, the written request by the Company to make such distribution shall be accompanied by a copy of the franchise tax bill from the State of Delaware for the Company and a written statement from the principal financial officer of
the Company setting forth the actual amount payable. The written request of the Company referenced above shall constitute presumptive evidence that the Company is entitled to said funds, and the Trustee shall have no responsibility to look beyond
said request (it being acknowledged and agreed that any such amount in excess of interest income earned on the Property shall not be payable from the Trust Account); 

(k)    Upon written request from the Company, which may be given from time to time in a form substantially similar to that

if the Company has not consummated an initial Business Combination within such time as is described in the Company’s amended and restated certificate of incorporation. The written request of the Company referenced above shall constitute
presumptive evidence that the Company is entitled to distribute said funds, and the Trustee shall have no responsibility to look beyond said request; and 

(l)    Not make any withdrawals or distributions from the Trust Account other than pursuant to
Section 1(i), (j) or (k) above.

Trustee shall be entitled to rely on, and shall be protected in relying on, any such written instructions and, further, any verbal or telephonic advice or instruction which it, in good faith and with reasonable care, believes to be given by any one
of the persons authorized above to give written instructions, provided that the Company shall promptly confirm such instructions in writing; 

  
 3 

 (b)    Subject to Section 4 hereof, hold the
Trustee harmless and indemnify the Trustee from and against any and all expenses, including reasonable counsel fees and disbursements, or losses suffered by the Trustee in connection with any action taken by it hereunder and in connection with any
action, suit or other proceeding brought against the Trustee involving any claim, or in connection with any claim or demand, which in any way arises out of or relates to this Agreement, the services of the Trustee hereunder, or the Property or any
interest earned on the Property, except for expenses and losses resulting from the Trustee’s gross negligence, fraud or willful misconduct. Promptly after the receipt by the Trustee of notice of demand or claim or the commencement of any
action, suit or proceeding, pursuant to which the Trustee intends to seek indemnification under this Section 2(b), it shall notify the Company in writing of such claim (hereinafter referred to as the “Indemnified
Claim”). The Trustee shall have the right to conduct and manage the defense against such Indemnified Claim; provided that the Trustee shall obtain the consent of the Company with respect to the selection of counsel, which consent
shall not be unreasonably withheld or delayed. The Trustee may not agree to settle any Indemnified Claim without the prior written consent of the Company, which such consent shall not be unreasonably withheld or delayed. The Company may participate
in such action with its own counsel; 
 (c)    Pay the Trustee the fees set forth on Schedule A hereto, including
an initial acceptance fee, annual administration fee, and transaction processing fee which fees shall be subject to modification by the parties from time to time. It is expressly understood that the Property shall not be used to pay such fees unless

Company the monthly fee (on a pro rata basis) with respect to any period after the liquidation of the Trust Account. The Company shall not be responsible for any other fees or charges of the Trustee except as set forth in this

(4) business days after the Underwriter exercises its option to purchase additional Units (or any unexercised portion thereof) or such over-allotment expires, provide the Trustee with a notice in writing of the total amount of the Deferred
Discount, which shall in no event be less than $10,500,000.

(g)    The other parties hereto or to anyone else for any action taken or omitted by it, or any action suffered by it to be
taken or omitted, in good faith and in the Trustee’s reasonable best judgment, except for the Trustee’s gross negligence, fraud or willful misconduct. The Trustee may rely conclusively and shall be protected in acting upon any order,
notice, demand, certificate, opinion or advice of counsel (including counsel chosen by the Trustee, which counsel may be the Company’s counsel), statement, instrument, report or other paper or document (not only as to its due execution and the
validity and effectiveness of its provisions, but also as to the truth and acceptability of any information therein contained) which the Trustee believes, in good faith and with reasonable care, to be genuine and to be signed or presented by the
proper person or persons. The Trustee shall not be bound by any notice or demand, or any waiver, modification, termination or rescission of this Agreement or any of the terms hereof, unless evidenced by a written instrument delivered to the Trustee,

Section 1(j) hereof; or 

  
 5 

 (l)    Verify calculations, qualify or otherwise approve the
Company’s written requests for distributions pursuant to Sections 1(i), 1(j) and 1(k) hereof. 

4.    Trust Account Waiver. The Trustee has no right of set-off or any
right, title, interest or claim of any kind (“Claim”) to, or to any monies in, the Trust Account, and hereby irrevocably waives any Claim to, or to any monies in, the Trust Account that it may have now or in the future. In
the event the Trustee has any Claim against the Company under this Agreement, including, without limitation, under Section 2(b) or Section 2(c) hereof, the Trustee shall pursue such Claim solely
against the Company and its assets outside the Trust Account and not against the Property or any monies in the Trust Account. 

5.    Termination. This Agreement shall terminate as follows: 

(a)    If the Trustee gives written notice to the Company that it desires to resign under this Agreement, the Company shall
use its reasonable efforts to locate a successor trustee, pending which the Trustee shall continue to act in accordance with this Agreement. At such time that the Company notifies the Trustee that a successor trustee has been appointed and has
agreed to become subject to the terms of this Agreement, the Trustee shall transfer the management of the Trust Account to the successor trustee, including but not limited to the transfer of copies of the reports and statements relating to the Trust
Account, whereupon this Agreement shall terminate; provided, however, that in the event that the Company does not locate a successor trustee within ninety (90) days of receipt of the resignation notice from the Trustee, the
Trustee may submit an application to have the Property deposited with any court in the State of New York or with the United States District Court for the Southern District of New York and upon such deposit, the Trustee shall be immune from any
liability whatsoever; or 
 (b)    At such time that the Trustee has completed the liquidation of the Trust Account and
its obligations in accordance with the provisions of Section 1(i) hereof and distributed the Property in accordance with the provisions of the Termination Letter, this Agreement shall terminate except with respect to
Section 2(b). 
 6.    Miscellaneous. 

(a)    The Company and the Trustee each acknowledge that the Trustee will follow the security procedures set forth below
with respect to funds transferred from the Trust Account. The Company and the Trustee will each restrict access to confidential information relating to such security procedures to authorized persons. Each party must notify the other party
immediately if it has reason to believe unauthorized persons may have obtained access to such confidential information, or of any change in its authorized personnel. In executing funds transfers, the Trustee shall rely upon all information supplied
to it by the Company, including, account names, account numbers, and all other identifying information relating to a Beneficiary, Beneficiary’s bank or intermediary bank. Except for any liability arising out of the Trustee’s gross
negligence, fraud or willful misconduct, the Trustee shall not be liable for any loss, liability or expense resulting from any error in the information or transmission of the funds. 

(b)    This Agreement shall be governed by and construed and enforced in accordance with the laws of the State of New York,
without giving effect to conflicts of law principles that would result in the application of the substantive laws of another jurisdiction. This Agreement may be executed in several original or facsimile counterparts, each one of which shall
constitute an original, and together shall constitute but one instrument.

 (c)    This Agreement contains the entire agreement and understanding of
the parties hereto with respect to the subject matter hereof. This Agreement or any provision hereof may only be changed, amended or modified (other than to correct a typographical error) by a writing signed by each of the parties hereto. 

(d)    This Agreement or any provision hereof may only be changed, amended or modified pursuant to
Section 6 hereof with the Consent of the Stockholders, it being the specific intention of the parties hereto that each of the Company’s stockholders is, and shall be, a third party beneficiary of this
Section 6(d) with the same right and power to enforce this Section 6 as the other parties hereto. For purposes of this Section 6(d), the “Consent of the
Stockholders” means receipt by the Trustee of a certificate from the inspector of elections of the stockholder meeting certifying that the Company’s stockholders of record as of a record date established in accordance with
Section 213(a) of the General Corporation Law of the State of Delaware, as amended (or any successor rule), who hold at least sixty-five percent (65%) of the voting power of all then outstanding shares of the Common Stock and Class B
common stock, par value $0.00001 per share, have voted in favor of such change, amendment or modification. No such amendment will affect any Public Stockholder who has otherwise indicated his election to redeem his share of Common Stock in
connection with a stockholder vote sought to amend this Agreement. Except for any liability arising out of the Trustee’s gross negligence, fraud or willful misconduct, the Trustee may rely conclusively on the certification from the inspector or
elections referenced above and shall be relieved of all liability to any party for executing the proposed amendment in reliance thereon. 

(e)    The parties hereto consent to the jurisdiction and venue of any state or federal court located in the City of New
York, State of New York, for purposes of resolving any disputes hereunder. AS TO ANY CLAIM, CROSS-CLAIM OR COUNTERCLAIM IN ANY WAY RELATING TO THIS AGREEMENT, EACH PARTY WAIVES THE RIGHT TO TRIAL BY JURY. 

(f)    Any notice, consent or request to be given in connection with any of the terms or provisions of this Agreement shall
be in writing and shall be sent by express mail or similar private courier service, by certified mail (return receipt requested), by hand delivery or by facsimile or email transmission:

Gentlemen: 
 Pursuant to Section 1(i) of

                    , 2021 (the “Trust Agreement”), this is to advise you that the Company has entered into an agreement with
                         (the “Target Business”) to consummate a business combination with Target
Business (the “Business Combination”) on or about                     , 20    . The Company shall notify
you at least forty-eight (48) hours in advance of the actual date of the consummation of the Business Combination (or such shorter time period as you may agree) (the “Consummation Date”). Capitalized terms used but not
defined herein shall have the meanings set forth in the Trust Agreement. 
 In accordance with the terms of the Trust Agreement, we hereby
authorize you to commence to liquidate all of the assets of the Trust Account on                     , 20    , and to transfer
the proceeds into a segregated account held by you on behalf of the Beneficiaries to the effect that, on the Consummation Date, all of the funds held in the Trust Account will be immediately available for transfer to the account or accounts that the
Company shall direct on the Consummation Date. It is acknowledged and agreed that while the funds are on deposit in the trust checking account at Bank of America, National Association, awaiting distribution, the Company will not earn any interest or
dividends. 
 On the Consummation Date (i) counsel for the Company shall deliver to you written notification that the Business
Combination has been consummated, or will be consummated concurrently with your transfer of funds to the accounts as directed by the Company (the “Notification”) and (ii) the Company shall deliver to you (a) [an
affidavit] [a certificate] of the Chief Executive Officer of the Company, which verifies that the Business Combination has been approved by a vote of the Company’s stockholders, if a vote is held and (b) a written instruction signed by the
Company with respect to the transfer of the funds held in the Trust Account, including payment of the Deferred Discount from the Trust Account (the “Instruction Letter”). You are hereby directed and authorized to transfer the
funds held in the Trust Account immediately upon your receipt of the Notification and the Instruction Letter, in accordance with the terms of the Instruction Letter. In the event that certain deposits held in the Trust Account may not be liquidated
by the Consummation Date without penalty, you will notify the Company in writing of the same and the Company shall direct you as to whether such funds should remain in the Trust Account and be distributed after the Consummation Date to the Company.
Upon the distribution of all the funds, net of any payments necessary for reasonable unreimbursed expenses related to liquidating the Trust Account, your obligations under the Trust Agreement shall be terminated. 

  
 A-1 

 In the event that the Business Combination is not consummated on the Consummation Date
described in the notice thereof and we have not notified you on or before the original Consummation Date of a new Consummation Date, then upon receipt by the Trustee of written instructions from the Company, the funds held in the Trust Account shall
be reinvested as provided in Section 1(c) of the Trust Agreement on the business day immediately following the Consummation Date as set forth in such written instruction as soon thereafter as possible.

 RE: Securities Subscription Agreement 

Ladies and Gentlemen: 
 NightDragon Acquisition
Corp., a Delaware corporation (the “Company”), is pleased to accept the offer NightDragon Acquisition Sponsor, LLC, a Delaware limited liability company (the “Sponsor”) has made to purchase 8,625,000 shares (the
“Shares”) of common stock, $0.00001 par value per share (the “Common Stock”). The terms (this “Agreement”) on which the Company is willing to sell the Shares to the Sponsor, and the Company and the
Sponsor’s agreements regarding the Shares, are as follows: 
 1. Purchase of Shares. For the sum of $25,000.00 which the Company
acknowledges receiving in cash, the Company hereby sells and issues the Shares to the Sponsor, and the Sponsor hereby purchases the Shares from the Company, on the terms and subject to the conditions set forth in this Agreement. 

2. Representations, Warranties and Agreements. 

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

2.1.3. Organization and Authority. The Sponsor is a Delaware limited liability company, validly existing and 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 Sponsor, this Agreement will be a legal, valid and binding agreement of the
Sponsor, enforceable against the Sponsor 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 Sponsor 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 of
1933, as amended (the “Securities Act”), and therefore cannot be resold unless subsequently registered under the Securities Act or an exemption from such registration is available. The Sponsor is capable of evaluating the merits and
risks of its investment in the Company and has the capacity to protect its own interests. The Sponsor 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 Sponsor is able to bear the economic risks of an investment in the Shares and to afford a complete loss of the Sponsor’s investment in the
Shares. 

 2.1.5. Access to Information; Independent Investigation. Prior to the execution of
this Agreement, the Sponsor 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 Sponsor has relied solely on the Sponsor’s own knowledge and understanding of the
Company and its business based upon the Sponsor’s own due diligence investigation and the information furnished pursuant to this paragraph. The Sponsor 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 the Sponsor has not relied on any other representations or information in making its investment decision, whether written or oral, relating to the Company, its operations
or its prospects. 
 2.1.6. Accredited Investor. The Sponsor represents that it is an “accredited investor” as such term is
defined in Rule 501(a) of Regulation D under the Securities Act, and acknowledges the sale contemplated hereby is being made in reliance on a private placement exemption applicable to “accredited investors” or similar exemptions under
federal and state law. 
 2.1.7. Investment Purposes. The Sponsor is purchasing the Shares solely for investment purposes, for the
Sponsor’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 Sponsor did not enter into this Agreement as a result of any general solicitation or
general advertising within the meaning of Rule 502 of Regulation D under the Securities Act. 
 2.1.8. Restrictions on Transfer; Shell
Company. The Sponsor understands the Shares are being offered in a transaction not involving a public offering within the meaning of the Securities Act. The Sponsor understands the Shares will be “restricted securities” as defined in
Rule 144(a)(3) under the Securities Act and the Sponsor understands that any certificate representing the Shares will contain a legend in respect of such restrictions. If in the future the Sponsor decides to offer, resell, pledge or otherwise
transfer the Shares, the Shares may be offered, resold, pledged or otherwise transferred only in accordance with the provisions of Section 4 hereof. The Sponsor agrees that if any transfer of the Shares or any interest therein is proposed to be
made, as a condition precedent to any such transfer, the Sponsor may be required to deliver to the Company an opinion of counsel satisfactory to the Company. Absent registration or an exemption, the Sponsor agrees not to resell any Shares. The
Sponsor further acknowledges that because the Company is a shell company, Rule 144 may not be available to the Sponsor for the resale of the Shares until one year following consummation of the initial business combination of the Company, despite
technical compliance with the certain 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 the Sponsor in connection with the transactions contemplated by this Agreement. 

2.2 Company’s Representations, Warranties and Agreements. To induce the Sponsor to purchase the Shares, the Company hereby
represents and warrants to the Sponsor and agrees with the Sponsor 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 Bylaws of the Company, (ii) any agreement, indenture or instrument to which the Company is a party, (iii) any law,
statute, rule or regulation to which the Company is subject, or (iv) 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 Sponsor 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 Sponsor in
writing, (b) transfer restrictions under federal and state securities laws, and (c) liens, claims or encumbrances imposed due to the actions of the Sponsor. 

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 seek to recover damages or to
obtain other relief in connection with any transactions. 
 3. Waiver of Liquidation Distributions; Redemption Rights. In connection
with the Shares purchased pursuant to this Agreement, the Sponsor 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 (“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 Sponsor purchases shares of Common Stock in the IPO or in the aftermarket, any additional shares of Common Stock so
purchased shall be eligible to receive any liquidating distributions by the Company. However, in no event will the Sponsor have the right to redeem any Shares for funds held in the Trust Account upon the successful completion of an initial business
combination by the Company. 
 4. Restrictions on Transfer. 

4.1. Securities Law Restrictions. In addition to any restrictions to be contained in that certain letter agreement to be dated as of the
closing of the IPO by and between the Sponsor and the Company (the “Insider Letter”), the Sponsor agrees not to sell, transfer, pledge, hypothecate or otherwise dispose of all or any part of the Shares unless and until
(a) there is then in effect a registration statement under the Securities Act covering such sale, transfer, pledge, hypothecation or disposition and such sale, transfer, pledge, hypothecation or disposition is made in accordance with such
registration statement or (b) the Company has received an opinion of counsel satisfactory to the Company that such sale, transfer, pledge, hypothecation or disposition will not require the registration of the Shares under the Securities Act
such sale, transfer, pledge, hypothecation or disposition is exempt from registration under the Securities Act and the rules and regulations promulgated thereunder. 

4.2.    Lock-Up. The Sponsor acknowledges that the Shares will be subject
to the lock-up provisions contained in the Insider Letter. 
 4.3. Stop-Transfer Notices. The
Sponsor agrees that, to ensure compliance with the restrictions referred to herein or any restrictions in the bylaws of the Company, the Company may issue appropriate “stop transfer” instructions to its transfer agent, if any, and that, if
the Company transfers its own securities, it may make appropriate notations to the same effect in its own records. 
 4.4. Refusal to
Transfer. The Company shall not be required (i) to transfer on its books any Shares that have been sold or otherwise transferred in violation of any of the provisions of this Agreement or any applicable provisions of the bylaws of the
Company or (ii) to treat as owner of such Shares or to accord the right to vote or pay dividends to any purchaser or other transferee to whom such Shares shall have been so transferred. 

4.5. Restrictive Legends. The Sponsor understands and agrees that the Company shall cause the legends set forth below, or substantially
equivalent legends, to be placed upon any certificate(s) evidencing ownership of the Shares (or upon a notice of issuance of uncertificated stock, as applicable), together with any other legends that may be required by the Company or by applicable
state or federal securities laws: 
 THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE
“ACT”) AND MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT OR, IN THE OPINION OF COUNSEL SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH OFFER, SALE OR
TRANSFER, PLEDGE OR HYPOTHECATION OTHERWISE COMPLIES WITH THE ACT. 

 THE SHARES REPRESENTED HEREBY ARE SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER, INCLUDING A LOCK-UP PERIOD IN THE EVENT OF A PUBLIC OFFERING AS SET FORTH IN THE SECURITIES SUBSCRIPTION AGREEMENT BETWEEN THE COMPANY AND THE ORIGINAL HOLDER OF THESE SHARES, A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL
OFFICE OF THE COMPANY. SUCH TRANSFER RESTRICTIONS, INCLUDING THE LOCK-UP PERIOD, ARE BINDING ON TRANSFEREES OF THESE SHARES. 

4.6. Additional Shares or Substituted Securities. In the event of the declaration of a stock dividend, the declaration of a special
dividend payable in a form other than shares of Common Stock, a spin-off, a stock split, an adjustment in conversion ratio, a recapitalization or a similar transaction affecting the Company’s outstanding
Common Stock without receipt of consideration, any new, substituted or additional securities or other property which are by reason of such transaction distributed with respect to the 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 or class of Shares subject to this Section 4. 

4.7. Restrictions Binding on Transferees. All transferees of Shares or any interest therein shall receive and hold such Shares or
interest subject to all of the provisions of this Agreement and any applicable restrictions in the bylaws of the Company, and there shall be no further transfer of such Shares except in accordance with the terms of this Agreement and any applicable
restrictions in the bylaws of the Company. 
 5. Other Agreements. 

5.1. Further Assurances. The Sponsor 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 in writing and delivered: (i) 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. 

The Sponsor acknowledges that, to the fullest extent permitted by law, any notice to stockholders given by the Company under the Delaware
General Corporation Law or the Company’s certificate of incorporation or bylaws may be given by electronic mail, when directed to the Sponsor’s electronic mail address as it appears on the records of the Company (including, but not limited
to, the electronic mail address identified below the Sponsor’s signature) unless the Sponsor has notified the Company in writing or by electronic transmission of an objection to receiving notice by electronic mail or such notice is prohibited
by Section 232(e) of the Delaware General Corporation Law. A notice by electronic mail must include a prominent legend that the communication is an important notice regarding the Company. Subject to the limitations set forth in
Section 232(g) of the Delaware General Corporation Law, the Sponsor further consents to the delivery of any notice to stockholders given by the Company under the Delaware General Corporation Law or the Company’s certificate of
incorporation or bylaws by (i) facsimile telecommunication directed to the facsimile number set forth below the Sponsor’s signature (or to any other facsimile number for the Sponsor in the Company’s records), (ii) posting on an
electronic network together with separate notice to the Sponsor of such specific posting or (iii) any other form of electronic transmission directed to the Sponsor. This consent may be revoked by the Sponsor by written notice or electronic
transmission to the Company and is subject to the limitations specified in Section 232(e) of the Delaware General Corporation Law. For purposes of this paragraph, “electronic mail,” “electronic mail address” and
“electronic transmission” have the meanings set forth in Section 232 of the Delaware General Corporation Law. 

 5.3. Entire Agreement. This Agreement, together with that certain Insider Letter to
be entered into between the Sponsor and the Company, substantially in the form to be filed as an exhibit to the registration statement relating to the Company’s IPO, embodies the entire agreement and understanding between the Sponsor 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 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 Delaware 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 hold 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 sections 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 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 section 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 Sponsor 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. 
 5.17.
Reliance on Counsel and Advisors. The Sponsor acknowledges that Wilson Sonsini Goodrich & Rosati, Professional Corporation, is representing only the Company in this transaction. The Sponsor acknowledges that the Sponsor has had the
opportunity to review this Agreement, including all attachments hereto, and the transactions contemplated by this Agreement with the Sponsor’s own legal counsel, tax advisors and other advisors. The Sponsor is relying solely on the
Sponsor’s own counsel and advisors and not on any statements or representations of the Company or its agents for legal or other advice with respect to this investment or the transactions contemplated by this Agreement. 

6. Voting and Redemption of Shares. The Sponsor 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 the Shares. Additionally, the Sponsor agrees not to redeem any Shares in connection with a redemption or tender offer presented to
the Company’s stockholders in connection with an initial business combination negotiated by the Company.
