EQRX,
INC.

 

EMPLOYEE
CONFIDENTIALITY, ASSIGNMENT AND NON-SOLICITATION AGREEMENT

 

In
consideration and as a condition of the commencement of my employment or my continued employment by EQRx, Inc. (including its subsidiaries
and other affiliates and its and their successors and assigns, the “Company”), I enter into this Employee Confidentiality,
Assignment and Non-Solicitation Agreement (the “Agreement”) and agree as follows:

 

1. Proprietary
Information. I agree that all information, whether or not in writing, concerning the Company’s business, technology, business
relationships or financial affairs that the Company has not released to the general public (collectively, “Proprietary Information”)
and all tangible embodiments thereof are and will be the exclusive property of the Company. By way of illustration, Proprietary Information
may include information or material that has not been made generally available to the public, such as: (a) corporate information,
including plans, strategies, methods, policies, resolutions, negotiations or litigation; (b) marketing information, including
strategies, methods, customer or business partner identities or other information about customers, business partners, prospect identities
or other information about prospects, or market analyses or projections; (c) financial information, including cost and performance
data, debt arrangements, equity structure, investors and holdings, purchasing and sales data and price lists; (d) operational, technological
and scientific information, including plans, specifications, manuals, forms, templates, software, testing data and strategies, pre-clinical
and clinical study data, research and development strategies, designs, methods, procedures, formulae, data, reports, discoveries, inventions,
improvements, concepts, ideas, and other Developments (as defined below), know-how and trade secrets; and (e) personnel information,
including personnel lists, reporting or organizational structure, resumes, personnel data, performance evaluations and termination arrangements
or documents. Proprietary Information also includes information received in confidence by the Company from its customers, suppliers,
business partners or other third parties.

 

2. Recognition
of Company’s Rights. I will not, at any time, without the Company’s prior written permission, either during or after
my employment, disclose any Proprietary Information to anyone outside of the Company, or use or permit to be used any Proprietary Information
for any purpose other than the performance of my duties as an employee of the Company. I will cooperate with the Company and use my best
efforts to prevent the unauthorized disclosure of all Proprietary Information. I will deliver to the Company all copies and other tangible
embodiments of Proprietary Information in my possession or control upon the earlier of a request by the Company or termination of my
employment.

 

3. Rights
of Others. I understand that the Company is now and may hereafter be subject to nondisclosure or confidentiality agreements with
third persons that require the Company to protect or refrain from use or disclosure of proprietary information. I agree to be bound by
the terms of such agreements in the event I have access to such proprietary information. I understand that the Company strictly prohibits
me from using or disclosing confidential or proprietary information belonging to any other person or entity (including any employer or
former employer), in connection with my employment. In addition, I agree not to bring any confidential information belonging to any other
person or entity onto Company premises or into Company workspaces.

 

     

     

    

 

4. Commitment
to Company; Avoidance of Conflict of Interest. While an employee of the Company, I will devote my full-time efforts to the Company’s
business and I will not, directly or indirectly, engage in any other business activity, except as expressly authorized in writing and
in advance by a duly authorized representative of the Company. I will advise an authorized officer of the Company or his or her designee
at such time as any activity of either the Company or another business presents me with a conflict of interest or the appearance of a
conflict of interest as an employee of the Company. I will take whatever action is requested of me by the Company to resolve any conflict
or appearance of conflict which it finds to exist.

 

5. Developments.
I will make full and prompt disclosure to the Company of all inventions, discoveries, designs, developments, methods, modifications,
improvements, processes, algorithms, data, databases, computer programs, research, formulae, techniques, trade secrets, graphics or images,
and audio or visual works and other works of authorship, and other intellectual property, including works-in-process (collectively “Developments”)
whether or not patentable or copyrightable, that are created, made, conceived or reduced to practice by me (alone or jointly with others)
or under my direction during the period of my employment. I acknowledge that all work performed by me is on a “work for hire”
basis, and I hereby do assign and transfer and, to the extent any such assignment cannot be made at present, will assign and transfer,
to the Company and its successors and assigns all my right, title and interest in and to all Developments that (a) relate to the business
of the Company or any customer of, supplier to or business partner of the Company or any of the products or services being researched,
developed, manufactured or sold by the Company or which may be used with such products or services; or (b) result from tasks assigned
to me by the Company; or (c) result from the use of premises or personal property (whether tangible or intangible) owned, leased or contracted
for by the Company (“Company-Related Developments”), and all related patents, patent applications, trademarks and
trademark applications, copyrights and copyright applications, sui generis database rights and other intellectual property rights
in all countries and territories worldwide and under any international conventions (“Intellectual Property Rights”).

 

To
preclude any possible uncertainty, if there are any Developments that I have, alone or jointly with others, conceived, developed or reduced
to practice prior to the commencement of my employment with the Company that I consider to be my property or the property of third parties
and that I wish to have excluded from the scope of this Agreement (“Prior Inventions”), I have set forth on Exhibit
A attached hereto a complete list of those Prior Inventions. If disclosure of any such Prior Invention would cause me to violate
any prior confidentiality agreement, I understand that I am not to list such Prior Inventions in Exhibit A but am only to disclose
a cursory name for each such invention, a listing of the party(ies) to whom it belongs and the fact that full disclosure as to such inventions
has not been made for that reason. If there are any patents or patent applications in which I am named as an inventor, other than those
that have been assigned to the Company (“Other Patent Rights”), I have also listed those Other Patent Rights on Exhibit
A. If no such disclosure is attached, I represent that there are no Prior Inventions or Other Patent Rights. If, in the course of
my employment with the Company, I incorporate a Prior Invention into a Company product, process or machine, research or development program,
or other work done for the Company, I hereby grant to the Company a nonexclusive, royalty-free, fully paid-up, irrevocable, worldwide
license (with the full right to sublicense through multiple tiers) to make, have made, modify, use, sell, offer for sale and import such
Prior Invention. Notwithstanding the foregoing, I will not incorporate, or permit to be incorporated, Prior Inventions in any Company-Related
Development without the Company’s prior written consent. In addition, I will not, without the Company’s prior written consent,
incorporate into any Company product or otherwise deliver to the Company any software code that is subject to any license that by its
terms requires, or conditions the use or distribution of such code on, the disclosure, licensing or distribution of such Company product
or any source code owned or licensed by the Company (e.g., software code licensed under the GNU GPL, LGPL or AGPL).

 

    2

     

    

 

This
Agreement does not obligate me to assign to the Company any Development that, in the sole judgment of the Company, reasonably exercised,
is developed entirely on my own time and does not relate to the business efforts or research and development efforts in which, during
the period of my employment, the Company actually is engaged or reasonably would be engaged, and does not result from the use of premises
or equipment owned or leased by the Company. However, I will also promptly disclose to the Company any such Developments for the purpose
of determining whether they qualify for such exclusion. I understand that to the extent this Agreement is required to be construed in
accordance with the laws of any state which precludes a requirement in an employee agreement to assign certain classes of inventions
made by an employee, this paragraph 5 will be interpreted not to apply to any invention that a court rules and/or the Company agrees
falls within such classes. I also hereby waive all claims to any moral rights or other special rights that I may have or accrue in any
Company-Related Developments.

 

6. Documents
and Other Materials. I will keep and maintain adequate and current records of all Proprietary Information and Company-Related
Developments developed by me during my employment, which records will be available to and remain the sole property of the Company at
all times.

 

All
files, letters, notes, memoranda, reports, records, data, sketches, drawings, notebooks, layouts, charts, quotations and proposals, specification
sheets, blueprints, models, prototypes, or other written, photographic or other tangible material containing Proprietary Information,
whether created by me or others, which come into my custody or possession, are the exclusive property of the Company to be used by me
only in the performance of my duties for the Company. Any property situated on the Company’s premises and owned by the Company,
including without limitation computers, disks and other storage media, filing cabinets or other work areas, is subject to inspection
by the Company at any time with or without notice. In the event of the termination of my employment for any reason, I will deliver to
the Company all Company property and equipment in my possession, custody or control, including all files, letters, notes, memoranda,
reports, records, data, sketches, drawings, notebooks, layouts, charts, quotations and proposals, specification sheets, blueprints, models,
prototypes, or other written, photographic or other tangible material containing Proprietary Information, and other materials of any
nature pertaining to the Proprietary Information of the Company and to my work, and will not take or keep in my possession any of the
foregoing or any copies.

 

7. Enforcement
of Intellectual Property Rights. I will cooperate fully with the Company, both during and after my employment with the Company,
with respect to the procurement, maintenance and enforcement of Intellectual Property Rights in Company-Related Developments. I will
sign, both during and after my employment, all papers, including without limitation copyright applications, patent applications, declarations,
oaths, assignments of priority rights, and powers of attorney, which the Company may deem necessary or desirable in order to protect
its rights and interests in any Company-Related Development or Intellectual Property Rights therein. If the Company is unable, after
reasonable effort, to secure my signature on any such papers, I hereby irrevocably designate and appoint each officer of the Company
as my agent and attorney-in-fact to execute any such papers on my behalf, and to take any and all actions as the Company may deem necessary
or desirable in order to protect its rights and interests in any Company-Related Development, including any Intellectual Property Rights
therein.

 

    3

     

    

 

8. Non-Solicitation.

 

In
order to protect the Company’s Proprietary Information and goodwill, during my employment and for a period of: (i) one (1) year
following the date of the cessation of my employment with the Company (the “Last Date of Employment”), or (ii) two
(2) years following the Last Date of Employment if I breach my fiduciary duty to the Company or if I have unlawfully taken, physically
or electronically, property belonging to the Company (in either case the “Restricted Period”):

 

(a) I
shall not, directly or indirectly, in any manner, other than for the benefit of the Company, solicit or transact any business with any
of the customers of the Company or any of its vendors. For purposes of this Agreement, (i) customers shall include then current customers
to which the Company provided products or services during the twelve months prior to the Last Date of Employment (the “One Year
Lookback”) and customer prospects that the Company solicited during the One Year Lookback and that I had significant contact
with or learned confidential information about in the course of my employment, and (ii) vendors shall include then current vendors and
vendors that provided services to or in connection with the Company during the One Year Lookback.

 

(b) I
shall not, directly or indirectly, in any manner, solicit, entice or attempt to persuade any employee or consultant of the Company to
leave the Company for any reason or otherwise participate in or facilitate the hire, directly or through another entity, of any person
who is then employed or engaged by the Company.

 

9. Government
Contracts. I acknowledge that the Company may have from time to time agreements with other persons or with the United States
Government or its agencies that impose obligations or restrictions on the Company regarding inventions made during the course of work
under such agreements or regarding the confidential nature of such work. I agree to comply with any such obligations or restrictions
upon the direction of the Company. In addition to the rights assigned under paragraph 5, I also assign to the Company (or any of its
nominees) all rights that I have or acquired in any Developments, full title to which is required to be in the United States under any
contract between the Company and the United States or any of its agencies.

 

10. Prior
Agreements. I hereby represent that, except as I have fully disclosed previously in writing to the Company, I am not bound by
the terms of any agreement with any previous or current employer or other party to refrain from using or disclosing any trade secret
or confidential or proprietary information in the course of my employment with the Company or to refrain from competing, directly or
indirectly, with the business of such employer or any other party. I further represent that my performance of all the terms of this Agreement
as an employee of the Company does not and will not breach any agreement to keep in confidence proprietary information, knowledge or
data acquired by me in confidence or in trust prior to my employment with the Company. I will not disclose to the Company or induce the
Company to use any confidential or proprietary information or material belonging to any previous employer or others.

 

11. Remedies
Upon Breach.  I understand that the restrictions contained in this Agreement are necessary for the protection of the business
and goodwill of the Company and I consider them to be reasonable for such purpose. Any breach of this Agreement is likely to cause the
Company substantial and irrevocable damage and therefore, in the event of such breach, the Company, in addition to such other remedies
which may be available, will be entitled to specific performance and other injunctive relief, without the posting of a bond. I further
acknowledge that a court may render an award extending the Restricted Period as one of the remedies in the event of my violation of this
Agreement. If I violate this Agreement, in addition to all other remedies available to the Company at law, in equity, and under contract,
I agree that I am obligated to pay all the Company’s costs of enforcement of this Agreement, including reasonable attorneys’
fees and expenses.

 

    4

     

    

 

12. Use
of Voice, Image and Likeness. I give the Company permission to use any and all of my voice, image and likeness, with or without
using my name, in connection with the products and/or services of the Company, for the purposes of advertising and promoting such products
and/or services and/or the Company, and/or for other purposes deemed appropriate by the Company in its reasonable discretion, except
to the extent prohibited by law.

 

13. No
Employment Obligation. I understand that this Agreement does not create an obligation on the Company or any other person to continue
my employment. I acknowledge that, unless otherwise agreed in a formal written employment agreement signed on behalf of the Company by
an authorized officer, my employment with the Company is at will and therefore may be terminated by the Company or me at any time and
for any reason, with or without cause.

 

14. Survival
and Assignment by the Company. I understand that my obligations under this Agreement will continue in accordance with its express
terms regardless of any changes in my title, position, duties, salary, compensation or benefits or other terms and conditions of employment.
I further understand that my obligations under this Agreement will continue following the termination of my employment regardless of
the manner of such termination and will be binding upon my heirs, executors and administrators. The Company will have the right to assign
this Agreement to its affiliates, successors and assigns. I expressly consent to be bound by the provisions of this Agreement for the
benefit of the Company or any parent, subsidiary or affiliate to whose employ I may be transferred without the necessity that this Agreement
be resigned at the time of such transfer.

 

15. Post-Employment
Notifications. During the Restricted Period, I will notify the Company of any change in my address and of each subsequent employment
or business activity, including the name and address of my employer or other post-Company employment plans and the nature of my activities.

 

16. Disclosures
During Restricted Period.  I will provide a copy of this Agreement to any person or entity with whom I may enter into a
business relationship, whether as an employee, consultant, partner, coventurer or otherwise, prior to entering into such business relationship
during the Restricted Period.

 

17. Severability.
In case any provisions (or portions thereof) contained in this Agreement shall, for any reason, be held invalid, illegal or unenforceable
in any respect, such invalidity, illegality or unenforceability shall not affect the other provisions of this Agreement, and this Agreement
shall be construed as if such invalid, illegal or unenforceable provision had never been contained herein. If, moreover, any one or more
of the provisions contained in this Agreement shall for any reason be held to be excessively broad as to duration, geographical scope,
activity or subject, it shall be construed by limiting and reducing it, so as to be enforceable to the extent compatible with the applicable
law as it shall then appear.

 

18. Waiver.
I acknowledge and agree that no waiver of any of my obligations under this Agreement shall be effective unless made in writing by the
Company. The failure of the Company to require my performance of any term or obligation of this Agreement, or the waiver of any breach
of this Agreement, shall not prevent the Company’s subsequent enforcement of such term or obligation or be deemed a waiver of any
subsequent breach.

 

19. Choice
of Law and Jurisdiction. This Agreement will be deemed to be made and entered into in the Commonwealth of Massachusetts, and
will in all respects be interpreted, enforced and governed under the laws of the Commonwealth of Massachusetts. I hereby consent to personal
jurisdiction of the state and federal courts situated within Massachusetts for purposes of enforcing this Agreement, and waive any objection
that I might have to personal jurisdiction or venue in those courts.

 

20. Independence
of Obligations. My obligations under this Agreement are independent of any obligation, contractual or otherwise, the Company
has to me. The Company’s breach of any such obligation shall not be a defense against the enforcement of this Agreement or otherwise
limit my obligations under this Agreement.

 

21. Protected
Disclosures. I understand that nothing contained in this Agreement limits my ability to communicate with any federal, state or
local governmental agency or commission, including to provide documents or other information, without notice to the Company. I also understand
that nothing in this Agreement limits my ability to share compensation information concerning myself or others, except that this does
not permit me to disclose compensation information concerning others that I obtain because my job responsibilities require or allow access
to such information.

 

22. Defend
Trade Secrets Act of 2016. I understand that pursuant to the federal Defend Trade Secrets Act of 2016, I shall not be held criminally
or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that (a) is made (i) in confidence
to a federal, state, or local government official, either directly or indirectly, or to an attorney; and (ii) solely for the purpose
of reporting or investigating a suspected violation of law; or (b) is made in a complaint or other document filed in a lawsuit or other
proceeding, if such filing is made under seal.

 

23. Entire
Agreement; Amendment. This Agreement constitutes the entire agreement between the Company and me with respect to the subject
matter hereof, and supersedes all prior agreements or understandings, both written and oral, between the Company and me with respect
to the subject matter hereof, but does not in any way merge with or supersede any other confidentiality, assignment of inventions or
other restrictive covenant agreement or obligation entered into by the Company and me, which agreements and obligations shall supplement,
and shall not limit or be limited by, this Agreement. This Agreement may be amended only in a written agreement executed by a duly authorized
officer of the Company and me.

Article
II

REGISTRATIONS

 

Section 2.1
Shelf Registration.

 

2.1.1
The Company shall, as soon as practicable, but in any event within 30 days after the Closing Date (the “Filing Deadline”),
file a Registration Statement under the Securities Act (the “Initial Shelf”) to permit the public resale of
all the Registrable Securities held by the Holders from time to time as permitted by Rule 415 under the Securities Act (or any successor
or similar provision adopted by the Commission then in effect) on the terms and conditions specified in this subsection 2.1.1
and shall use its commercially reasonable efforts to cause such Initial Shelf to be declared effective as soon as practicable after the
filing thereof, but in no event later than the earlier of (i) 60 days following the Filing Deadline and (ii) five Business Days after
the Commission notifies the Company that it will not review the Initial Shelf, if applicable (the “Effectiveness Deadline”);
provided that the Effectiveness Deadline shall be extended to 90 days after the Filing Deadline if the Initial Shelf is reviewed
by, and receives comments from, the Commission. Without limiting the foregoing, as soon as practicable, but in no event later than three
Business Days, following the resolution or clearance of all Commission comments or, if applicable, following notification by the Commission
that the Initial Shelf or any amendment thereto will not be subject to review, the Company shall file a request for acceleration of effectiveness
of such Initial Shelf (to the extent required, by declaration or ordering of effectiveness, of such Initial Shelf or amendment thereto
by the Commission) to a time and date not later than two Business Days after the submission of such request. The Initial Shelf filed with
the Commission pursuant to this subsection 2.1.1 shall be on Form S-1 or such other form of registration statement as is then available
to effect a registration for resale of the Registrable Securities, provided, that the Company shall file, within 30 days of such time
as Form S-3 is available for the Initial Shelf, a post-effective amendment to the Initial Shelf then in effect, or otherwise file a Registration
Statement on Form S-3, registering the Registrable Securities for resale on Form S-3 (provided that the Company shall use commercially
reasonable efforts to maintain the effectiveness of the Initial Shelf then in effect until such time as a Registration Statement (or post-effective
amendment) on Form S-3 covering such Registrable Securities has been declared effective by the Commission). The Initial Shelf shall cover
all Registrable Securities, and shall contain a Prospectus in such form as permits any Holder to sell such Registrable Securities pursuant
to Rule 415 under the Securities Act (or any successor or similar provision adopted by the Commission then in effect) at any time beginning
on the effective date for such Initial Shelf and the Company shall file with the Commission the final form of such Prospectus pursuant
to Rule 424 (or successor thereto) under the Securities Act no later than the second Business Day after the Initial Shelf becomes effective.
The Initial Shelf shall provide for the resale pursuant to any method or combination of methods legally available to, and requested by,
the Holders and shall include a customary “plan of distribution” permitting all lawful means of disposition of the Registrable
Securities by the Holders, including block sales, agented transactions, sales directly into the market, distributions to affiliates, partners
or equityholders and other customary provisions. The Company shall use its commercially reasonable efforts to cause the Initial Shelf
to remain effective, and to be supplemented and amended to the extent necessary to ensure that the Initial Shelf is available or, if not
available, that another Registration Statement is available at all times, for the public resale of all the Registrable Securities held
by the Holders until all such Registrable Securities have ceased to be Registrable Securities. As soon as practicable following the effective
date of the Initial Shelf, but in any event within three Business Days of such date, the Company shall notify the Holders of the effectiveness
of such the Initial Shelf.

 

2.1.2
Form of Registration. If the Company files the Initial Shelf on Form S-3 (a “Form S-3 Shelf”)
and thereafter the Company becomes ineligible to use Form S-3 for secondary sales, the Company shall use its commercially reasonable efforts
to file the Initial Shelf on Form S-1 as promptly as practicable to replace the shelf registration statement that is on Form S-3 and have
the Initial Shelf declared effective as promptly as practicable and to cause such Initial Shelf to remain effective, and to be supplemented
and amended to the extent necessary to ensure that such Initial Shelf is available or, if not available, that another Registration Statement
is available, for the public resale of all the Registrable Securities held by the Holders until all such Registrable Securities have ceased
to be Registrable Securities.

 

    8

     

    

 

2.1.3
Underwritten Shelf Takedowns. At any time and from time to time following the effectiveness of the Initial Shelf, any Holder
may request to sell all or a portion of their Registrable Securities in a Shelf Underwritten Offering; provided that such Holder(s)
reasonably expects to sell Registrable Securities yielding aggregate gross proceeds in excess of $50,000,000 from such Shelf Underwritten
Offering (such amount of Registrable Securities, the “Minimum Amount”). All requests for a Shelf Underwritten
Offering shall be made by giving written notice to the Company (the “Shelf Take Down Notice”). Each Shelf Take
Down Notice shall specify the approximate number of Registrable Securities proposed to be sold in the Shelf Underwritten Offering and
the expected price range (net of underwriting discounts and commissions) of such Shelf Underwritten Offering. Except with respect to any
Registrable Securities distributed by the Sponsor to its members following the expiration of the Initial Sponsor Shares Lock-up Period,
the Final Sponsor Shares Lock-up Period or the Private Placement Lock-up Period, as applicable, within five days after receipt of any
Shelf Take Down Notice, the Company shall, subject to subsections 3.5.3 and 3.5.4 (collectively, the “MNPI Provisions”),
give written notice of such requested Shelf Underwritten Offering to all other Holders of Registrable Securities (the “Company
Shelf Takedown Notice”) and, subject to the provisions of subsection 2.2.4, shall include in such Shelf Underwritten
Offering all Registrable Securities with respect to which the Company has received written requests for inclusion therein, within five
days after sending the Company Shelf Takedown Notice. The Company shall enter into an underwriting agreement in a form as is customary
in Underwritten Offerings of securities by the Company with the managing Underwriter or Underwriters selected by the Holders holding a
majority-in-interest of the Registrable Securities to be included in such Shelf Underwritten Offering after consultation with, and approval
(which shall not be unreasonably withheld, conditioned or delayed) by, the Company and shall take all such other reasonable actions as
are requested by the managing Underwriter or Underwriters in order to expedite or facilitate the disposition of such Registrable Securities.
In connection with any Shelf Underwritten Offering contemplated by this subsection 2.1.3, subject to Section 3.3 and Article
IV, the underwriting agreement into which each Holder and the Company shall enter shall contain such representations, covenants, indemnities
and other rights and obligations of the Company and the selling stockholders as are customary in underwritten offerings of securities
by the Company. The New Holders, on the one hand, and the Existing Holders, on the other hand, may each demand not more than two Shelf
Underwritten Offerings pursuant to this subsection 2.1.3 in any 12-month period.

 

2.1.4 At least 10 Business Days prior to the first anticipated filing date of a Registration Statement pursuant to this Article II,
the Company shall use reasonable efforts to notify each Holder in writing (which may be by email) of the information reasonably necessary
about the Holder to include such Holder’s Registrable Securities in such Registration Statement. Notwithstanding anything else in
this Agreement, the Company shall not be obligated to include such Holder’s Registrable Securities to the extent the Company has
not received such information, and received any other reasonably requested agreements or certificates, on or prior to the third Business
Day prior to the first anticipated filing date of a Registration Statement pursuant to this Article II.

 

2.1.5 Notwithstanding the registration obligations set forth in this Section 2, in the event that, despite the Company’s
efforts to include all of the Registrable Securities in any Registration Statement filed pursuant to subsection 2.1.1, the Commission
informs the Company (the “Commission’s Notice”) that all of the Registrable Securities cannot, as a result
of the application of Rule 415 or otherwise, be registered for resale as a secondary offering on a single Registration Statement, the
Company agrees to promptly (i) inform each of the holders thereof and use its commercially reasonable efforts to file amendments to the
Initial Shelf as required by the Commission and (ii) as soon as practicable but in no event later than the 20th day following the first
date on which such Registrable Securities may then be included in a Registration Statement, file an additional Registration Statement
(a “New Registration Statement”), on Form S-3, or if Form S-3 is not then available to the Company for such
Registration Statement, on such other form available to register for resale the Registrable Securities as a secondary offering; provided,
however, that prior to filing such amendment or New Registration Statement, the Company shall be obligated to use its commercially reasonable
efforts to advocate with the Commission for the registration of all of the Registrable Securities in accordance with any publicly-available
written or oral guidance, comments, requirements or requests of the Commission staff (the “SEC Guidance”), including
without limitation, the Manual of Publicly Available Telephone Interpretations D.29. The Holders shall have the right to participate or
have their respective legal counsel participate in any meetings or discussions with the Commission regarding the Commission’s position
and to comment or have their respective counsel comment on any written submission made to the Commission with respect thereto. No such
written submission shall be made to the Commission to which any Holder’s counsel reasonably objects. Notwithstanding any other provision
of this Agreement, if any SEC Guidance sets forth a limitation of the number of Registrable Securities permitted to be registered on a
particular Registration Statement as a secondary offering, unless otherwise directed in writing by a holder as to its Registrable Securities
directing the inclusion of less than such holder’s pro rata amount, the number of Registrable Securities to be registered on such
Registration Statement will be reduced on a pro rata basis based on the total number of Registrable Securities held by the Holders. In
the event the Company amends the Initial Shelf or files a New Registration Statement, as the case may be, under clauses (i) or (ii) above,
the Company will use its commercially reasonable efforts to file with the Commission, as promptly as allowed by Commission or SEC Guidance
provided to the Company or to registrants of securities in general, one or more Registration Statements on Form S-3 or such other form
available to register for resale those Registrable Securities that were not registered for resale on the Initial Shelf, as amended, or
the New Registration Statement.

 

    9

     

    

 

2.1.6 No
Holder shall be named as an “underwriter” in any Registration Statement filed pursuant to this Section 2 without
the Holder’s prior written consent; provided that if the Commission requests that a Holder be identified as a statutory
underwriter in the Registration Statement, then such Holder will have the option, in its sole and absolute discretion, to either (i)
have the opportunity to withdraw from the Registration Statement upon its prompt written request to the Company, in which case the
Company’s obligation to register such Holder’s Registrable Securities shall be deemed satisfied or (ii) be included as
such in the Registration Statement. Each Registration Statement (and each amendment or supplement thereto) shall be provided to (and
shall be subject to the approval, which shall not be unreasonably withheld or delayed, of) the Holders prior to its filing with, or
other submission to, the Commission.

 

2.1.7 In the event that on
any Trading Day (as defined below) (the “Registration Trigger Date”) the number of shares available under
the Registration Statements filed pursuant to this Section 2 is insufficient to cover all of the Registrable Securities
(without giving effect to any limitations on the exercise or conversion of any securities exercisable for, or convertible into,
Registrable Securities and, in the case of Registrable Securities issuable upon the exercise of warrants, assuming the exercise of
such warrants for cash), the Company shall amend such Registration Statements, or file a new Registration Statement (on the short
form available therefor, if applicable), or both, so as to cover the total number of Registrable Securities so issued or issuable
(without giving effect to any limitations on the exercise or conversion of any securities exercisable for, or convertible into,
Registrable Securities and, in the case of Registrable Securities issuable upon the exercise of warrants, assuming the exercise of
such warrants for cash) as of the Registration Trigger Date as soon as practicable, but in any event within 15 days after the
Registration Trigger Date. The Company shall use its commercially reasonable efforts to cause such amendment and/or new Registration
Statement to become effective as soon as practicable following the filing thereof, but in any event no later than 60 days of the
Registration Trigger Date (or 90 days if the applicable Registration Statement or amendment is reviewed by, and comments are thereto
provided from, the Commission) or as promptly as practicable in the event the Company is required to increase its authorized shares.
“Trading Day” shall mean any day on which the Class A Common Stock is traded for any period on the
principal securities exchange or market on which the Class A Common Stock is then being traded.

 

Section 2.2
Demand Registration.

 

2.2.1 Request
for Registration. Subject to the provisions of subsections 2.2.4 and 2.2.5 and Section 3.4 hereof, and provided
that the Company does not have an effective Registration Statement pursuant to subsection 2.1.1, outstanding covering all of
the Registrable Securities, following the expiration of the Founder Shares Lock-up Period, the Initial Sponsor Shares Lock-up
Period, the Final Sponsor Shares Lock-up Period, the Private Placement Lock-up Period or any other applicable lock-up period, as the
case may be, a Demanding Holder may make a written demand for Registration of all or part of their Registrable Securities, which
written demand shall describe the amount and type of securities to be included in such Registration and the intended method(s) of
distribution thereof (such written demand a “Demand Registration”). Subject to the MNPI Provisions, the
Company shall, within five days of the Company’s receipt of the Demand Registration, notify, in writing all other Holders of
Registrable Securities of such demand, and each Holder of Registrable Securities who thereafter wishes to include all or a portion
of such Holder’s Registrable Securities in a Registration pursuant to a Demand Registration (each such Holder that includes
all or a portion of such Holder’s Registrable Securities in such Registration, a “Requesting
Holder”) shall so notify the Company, in writing, within five days after the receipt by the Holder of the notice from
the Company. Upon receipt by the Company of any such written notification from a Requesting Holder(s) to the Company, subject to subsection
2.2.4 below, such Requesting Holder(s) shall be entitled to have their Registrable Securities included in a Registration
pursuant to a Demand Registration and the Company shall effect, as soon thereafter as practicable, but not more than 60 days
immediately after the Company’s receipt of the Demand Registration, the Registration of all Registrable Securities requested
by the Demanding Holders and Requesting Holders pursuant to such Demand Registration. Under no circumstances shall the Company be
obligated to effect more than an aggregate of three Registrations pursuant to a Demand Registration by the Existing Holders and an
aggregate of three Registrations pursuant to a Demand Registration by the New Holders under this subsection 2.1.1 with
respect to any or all Registrable Securities. Notwithstanding the foregoing, (i) the Company shall not be required to give effect to
a Demand Registration from a Demanding Holder if the Company has registered Registrable Securities pursuant to a Demand Registration
(which has become effective) from such Demanding Holder in the preceding 120 days, and (ii) the Company’s obligations with
respect to any Demand Registration shall be deemed satisfied so long as the Registration Statement filed pursuant to subsection
2.1.1 includes all of such Demanding Holder’s Registrable Securities and is effective. The registration statement
effecting such Demand Registration shall provide for the sale or resale pursuant to any method or combination of methods legally
available to, and requested by, the Holders and shall include a customary “plan of distribution” permitting all lawful
means of disposition of the Registrable Securities by the Holders, including block sales, agented transactions, sales directly into
the market, distribution to affiliates, partners or equityholders and other customary provisions.

 

    10

     

    

 

2.2.2
Effective Registration. Notwithstanding the provisions of subsection 2.2.1 above or any other part of this Agreement,
a Registration pursuant to a Demand Registration shall not count as a Registration unless and until (a) the Registration Statement filed
with the Commission with respect to a Registration pursuant to a Demand Registration has been declared effective by the Commission and,
(b) the Company has complied with all of its obligations under this Agreement with respect thereto; provided, further, that
if, after such Registration Statement has been declared effective, an offering of Registrable Securities in a Registration pursuant to
a Demand Registration is subsequently interfered with by any stop order or injunction of the Commission, federal or state court or any
other governmental agency, the Registration Statement with respect to such Registration shall be deemed not to have been declared effective,
unless and until, (i) such stop order or injunction is removed, rescinded or otherwise terminated, and (ii) a majority-in-interest of
the Demanding Holders initiating such Demand Registration thereafter affirmatively elect to continue with such Registration and accordingly
notify the Company in writing, but in no event later than five days thereafter, of such election. The Company shall not be obligated or
required to file another Registration Statement until the Registration Statement that has been previously filed with respect to a Registration
pursuant to a Demand Registration by the same Demanding Holder becomes effective or is subsequently terminated.

 

2.2.3
Underwritten Offering. Subject to the provisions of subsection 2.2.4 and Section 3.4 hereof, if a majority-in-interest
of the Demanding Holders so advise the Company as part of their Demand Registration that the offering of the Registrable Securities pursuant
to such Demand Registration shall be in the form of an Underwritten Offering, then the right of such Demanding Holder or Requesting Holder
(if any) to include its Registrable Securities in such Registration shall be conditioned upon such Holder’s participation in such
Underwritten Offering and the inclusion of such Holder’s Registrable Securities in such Underwritten Offering to the extent provided
herein. All such Holders proposing to distribute their Registrable Securities through an Underwritten Offering under this subsection
2.2.3, subject to Section 3.3 and Article IV, shall enter into an underwriting agreement in customary form with the
Company and the Underwriter(s) selected for such Underwritten Offering by a majority-in-interest of the Demanding Holders initiating the
Demand Registration after consultation with, and approval by, the Company (which shall not be unreasonably withheld, conditioned or delayed).

 

2.2.4
Reduction of Underwritten Offering. If a Demand Registration is to be an Underwritten Offering and the managing Underwriter
or Underwriters, in good faith, advises the Company, the Demanding Holders and the Requesting Holders (if any) in writing that, in its
opinion, the dollar amount or number of Registrable Securities that the Demanding Holders and the Requesting Holders (if any) desire to
sell, taken together with all other Class A Common Stock or other equity securities that the Company desires to sell for its own account
and the Class A Common Stock, if any, as to which a Registration has been requested pursuant to separate written contractual piggy-back
registration rights held by any other stockholders of the Company who desire to sell, exceeds the maximum dollar amount or maximum number
of equity securities that can be sold in such Underwritten Offering without adversely affecting the proposed offering price, the timing,
the distribution method, or the probability of success of such offering (such maximum dollar amount or maximum number of such securities,
as applicable, the “Maximum Number of Securities”), then the Company shall include in such Underwritten Offering,
as follows:

 

(a)
first, the Registrable Securities of the Demanding Holders and the Requesting Holders (if any) (pro rata based on the respective
number of Registrable Securities held by each Demanding Holder and Requesting Holder (if any) and the aggregate number of Registrable
Securities held by the Demanding Holders and Requesting Holders (such proportion is referred to herein as “Pro Rata”))
that can be sold without exceeding the Maximum Number of Securities;

 

(b)
second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (a), the Registrable
Securities of Holders (Pro Rata, based on the respective number of Registrable Securities held by each Holder) exercising their rights
to register their Registrable Securities pursuant to subsection 2.3.1 hereof, without exceeding the Maximum Number of Securities;

 

(c)
third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (a) and (b),
the Class A Common Stock or other equity securities that the Company desires to sell for its own account, which can be sold without exceeding
the Maximum Number of Securities; and

 

(d)
fourth, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (a), (b) and
(c), the Class A Common Stock or other equity securities of other persons or entities that the Company is obligated to register
in a Registration pursuant to separate written contractual arrangements with such persons and that can be sold without exceeding the Maximum
Number of Securities.

 

    11

     

    

 

2.2.5
Demand Registration Withdrawal. A Demanding Holder or a Requesting Holder shall have the right to withdraw all or a portion
of its Registrable Securities included in a Demand Registration pursuant to subsection 2.2.1 or a Shelf Underwritten Offering pursuant
to subsection 2.1.3 for any or no reason whatsoever upon written notification to the Company and the Underwriter or Underwriters
(if any) of its intention to so withdraw (“Withdrawal Notice”) (a) in the case of a Demand Registration
not involving an Underwritten Offering, one Business Day prior to the effectiveness of the applicable Registration Statement or (b) in
the case of any Demand Registration involving an Underwritten Offering or any Shelf Underwritten Offering, prior to the pricing of such
Underwritten Offering or Shelf Underwritten Offering; provided, however, that upon withdrawal by a majority-in-interest
of the Demanding Holders initiating a Demand Registration (or in the case of a Shelf Underwritten Offering, withdrawal of an amount of
Registrable Securities included by the Holders in such Shelf Underwritten Offering, in their capacity as Demanding Holders, being less
than the Minimum Amount), the Company shall cease all efforts to secure effectiveness of the applicable Registration Statement or complete
the Underwritten Offering, as applicable. For the avoidance of doubt, any Demand Registration withdrawn pursuant to this subsection
2.2.5 shall be counted toward the aggregate number of Demand Registrations the Company is obligated to effect pursuant to subsection
2.2.1 unless (A)(1) the Demanding Holders reimburse the Company for all of its out-of-pocket costs and expenses incurred in connection
with any such withdrawn Demand Registration incurred through the date of such withdrawal and (2) such revocation or withdrawal shall have
been made prior to the commencement of any marketing efforts or “road shows” by the Company or the underwriters in connection
with such Demand Registration, or (B) such withdrawal or revocation occurs following the issuance by the Company of a Suspension Notice.
Notwithstanding anything to the contrary in this Agreement, the Company shall be responsible for the Registration Expenses incurred by
it in connection with a Registration pursuant to a Demand Registration or a Shelf Underwritten Offering prior to its withdrawal under
this subsection 2.2.5.

 

Section 2.3
Piggyback Registration.

 

2.3.1
Piggyback Rights. If the Company proposes to file a Registration Statement under the Securities Act with respect to an offering
of equity securities, or securities or other obligations exercisable or exchangeable for, or convertible into equity securities, for its
own account or for the account of stockholders of the Company (or by the Company and by the stockholders of the Company including, without
limitation, pursuant to Section 2.2 hereof), other than a Registration Statement (a) filed in connection with any employee stock
option or other benefit plan, (b) for an exchange offer or offering of securities solely to the Company’s existing stockholders,
(c) for an offering solely of debt that is convertible into equity securities of the Company, (d) for a dividend reinvestment plan, (e)
for any issuances of securities in connection with a transaction involving a merger, consolidation, sale, exchange, issuance, transfer,
reorganization or other extraordinary transaction between the Company or any of its Affiliates and any third party, or (f) filed pursuant
to subsection 2.1.1, then, subject to the MNPI Provisions, the Company shall give written notice of such proposed filing to all
of the Holders of Registrable Securities (excluding the Sponsor with respect to any Registrable Securities distributed by the Sponsor
to its members following the expiration of the Initial Sponsor Shares Lock-up Period, the Final Sponsor Shares Lock-up Period or the Private
Placement Lock-up Period, as applicable) as soon as practicable but not less than 20 days before the anticipated filing date of such Registration
Statement, which notice shall (i) describe the amount and type of securities to be included in such offering, the intended method(s) of
distribution (including whether such registration will be pursuant to a shelf registration statement), and the proposed price and name
of the proposed managing Underwriter or Underwriters, if any, in such offering, (ii) describe such Holders’ rights under this Section
2.3, and (iii) offer to all of the Holders of Registrable Securities the opportunity to register the sale of such number of Registrable
Securities as such Holders may request in writing within five days after receipt of such written notice (such Registration, a “Piggyback
Registration”). The Company shall, in good faith, cause such Registrable Securities identified in a Holder’s response
noticed described in the foregoing sentence to be included in such Piggyback Registration and shall use its commercially reasonable efforts
to cause the managing Underwriter or Underwriters of a proposed Underwritten Offering, if any, to permit the Registrable Securities requested
by the Holders pursuant to this subsection 2.3.1 to be included in a Piggyback Registration on the same terms and conditions as
any similar securities of the Company or Company stockholder(s) for whose account the Registration Statement is to be filed included in
such Registration and to permit the sale or other disposition of such Registrable Securities in accordance with the intended method(s)
of distribution thereof. The registration statement effecting such Piggyback Registration shall provide for the sale or resale pursuant
to any method or combination of methods legally available to, and requested by, the Holders and shall include a customary “plan
of distribution” permitting all lawful means of disposition of the Registrable Securities by the Holders, including block sales,
agented transactions, sales directly into the market, distribution to affiliates, partners or equityholders and other customary provisions.
All such Holders proposing to distribute their Registrable Securities through an Underwritten Offering under this subsection 2.3.1,
subject to Section 3.3 and Article IV, shall enter into an underwriting agreement in customary form with the Underwriter(s)
selected for such Underwritten Offering by the Company.

2.3.2
Reduction of Piggyback Registration. If the managing Underwriter or Underwriters in an Underwritten Registration that is
to be a Piggyback Registration, in good faith, advises the Company and the Holders of Registrable Securities participating in the Piggyback
Registration in writing that, in its opinion, the dollar amount or number of the Class A Common Stock that the Company desires to sell,
taken together with (a) the Class A Common Stock, if any, as to which Registration has been demanded pursuant to separate written contractual
arrangements with persons or entities other than the Holders of Registrable Securities hereunder, (b) the Registrable Securities as to
which registration has been requested pursuant to Section 2.3 hereof, and (c) the Class A Common Stock, if any, as to which Registration
has been requested pursuant to separate written contractual piggy-back registration rights of other stockholders of the Company, exceeds
the Maximum Number of Securities, then:

 

2.3.2.1
if the Registration is undertaken for the Company’s account, the Company shall include in any such Registration (a) first,
the Class A Common Stock or other equity securities that the Company desires to sell, which can be sold without exceeding the Maximum
Number of Securities; (b) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause
(a), the Registrable Securities of Holders exercising their rights to register their Registrable Securities pursuant to subsection
2.3.1 hereof, Pro Rata, which can be sold without exceeding the Maximum Number of Securities; and (c) third, to the extent that the
Maximum Number of Securities has not been reached under the foregoing clauses (a) and (b), the Class A Common Stock, if
any, as to which Registration has been requested pursuant to written contractual piggy-back registration rights of other stockholders
of the Company, which can be sold without exceeding the Maximum Number of Securities; and

 

2.3.2.2
if the Registration is pursuant to a request by persons or entities other than the Holders of Registrable Securities, then the
Company shall include in any such Registration (a) first, the Class A Common Stock or other equity securities, if any, of such requesting
persons or entities, other than the Holders of Registrable Securities, which can be sold without exceeding the Maximum Number of Securities;
(b) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (a), the Registrable
Securities of Holders exercising their rights to register their Registrable Securities pursuant to subsection 2.3.1 hereof, Pro
Rata, which can be sold without exceeding the Maximum Number of Securities; (c) third, to the extent that the Maximum Number of Securities
has not been reached under the foregoing clauses (a) and (b), the Class A Common Stock or other equity securities that the
Company desires to sell for its own account, which can be sold without exceeding the Maximum Number of Securities; and (d) fourth, to
the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (a), (b) and (c),
the Class A Common Stock or other equity securities for the account of other persons or entities that the Company is obligated to register
pursuant to separate written contractual arrangements with such persons or entities, which can be sold without exceeding the Maximum Number
of Securities.

 

    13

     

    

 

2.3.3
Piggyback Registration Withdrawal. Any Holder of Registrable Securities shall have the right to withdraw all or any portion
of its Registrable Securities in a Piggyback Registration for any or no reason whatsoever upon written notification to the Company and
the Underwriter or Underwriters (if any) of his, her or its intention to withdraw such Registrable Securities from such Piggyback Registration
(a) in the case of a Piggyback Registration not involving an Underwritten Offering or Shelf Underwritten Offering, one Business Day prior
to the effectiveness of the applicable Registration Statement or (b) in the case of any Piggyback Registration involving an Underwritten
Offering or any Shelf Underwritten Offering, two Business Days prior to the pricing of such Underwritten Offering or Shelf Underwritten
Offering. The Company (whether on its own good-faith determination or as the result of a request for withdrawal by persons pursuant to
separate written contractual obligations) may withdraw a Registration Statement filed with the Commission in connection with a Piggyback
Registration at any time prior to the effectiveness of such Registration Statement.

 

2.3.4
Unlimited Piggyback Registration Rights. For purposes of clarity, any Registration effected pursuant to Section 2.3
hereof shall not be counted as a Registration pursuant to a Demand Registration effected under Section 2.2 hereof or a Shelf Underwritten
Offering effected under subsection 2.1.3.

 

Section 2.4
Reserved.

 

Section 2.5
Block Trades.

 

2.5.1
Notwithstanding any other provision of this Agreement, but subject to Section 3.4, if a Demanding Holder desires to effect
a Block Trade with a total offering price reasonably expected to exceed, in the aggregate, either (x) the Minimum Amount or (y) all remaining
Registrable Securities held by the Demanding Holder, then notwithstanding the time periods provided for in subsection 2.1.4, such
Demanding Holder shall notify the Company of the Block Trade at least five Business Days prior to the day such offering is to commence
and the Company shall as expeditiously as possible use its commercially reasonable efforts to facilitate such Block Trade; provided
that the Demanding Holders wishing to engage in the Block Trade shall use commercially reasonable efforts to work with the Company and
any Underwriters or placement agents or sales agents prior to making such request in order to facilitate preparation of the registration
statement, prospectus and other offering documentation related to the Block Trade.

 

2.5.2
Prior to the filing of the applicable “red herring” prospectus or prospectus supplement used in connection with a Block
Trade, any Demanding Holders shall have the right to submit a Withdrawal Notice to the Company and the Underwriter or Underwriters or
placement agents or sales agents (if any) of their intention to withdraw from such Block Trade.

 

Section 2.6
Market Stand-Off. In connection with any Underwritten Offering of equity securities of the Company (other than a Block Trade),
each Holder participating in the Underwritten Offering pursuant to the terms of this Agreement agrees that it shall not Transfer any shares
of Class A Common Stock or other equity securities of the Company (other than those included in such offering pursuant to this Agreement),
without the prior written consent of the Company, during the 90-day period beginning on the date of pricing of such offering or such shorter
period during which the Company agrees not to conduct an underwritten primary offering of Class A Common Stock, except in the event the
Underwriters managing the offering otherwise agree by written consent. Each Holder participating in the Underwritten Offering agrees to
execute a customary lock-up agreement in favor of the Underwriters to such effect (in each case on substantially the same terms and conditions
as all such Holders).

III

COMPANY PROCEDURES

 

Section 3.1
General Procedures. If the Company is required to effect the Registration of Registrable Securities, the Company shall use

of distribution set forth in such Registration Statement or supplement to the Prospectus;

exhibits thereto and documents incorporated by reference therein), the Prospectus included in such Registration Statement (including each
preliminary Prospectus), and such other documents as the Underwriters and the Holders of Registrable Securities included in such Registration

3.1.4
prior to any public offering of Registrable Securities, but in any case no later than the effective date of the applicable Registration
Statement, use its commercially reasonable efforts to (a) register or qualify the Registrable Securities covered by the Registration Statement

included in such Registration Statement (in light of their intended plan of distribution) may request and to keep such registration or
qualification in effect for so long as such Registration Statement remains in effect, and (b) take such action necessary to cause such
Registrable Securities covered by the Registration Statement to be registered with or approved by such other governmental authorities
or securities exchanges, including the applicable Nasdaq Stock Market (“Nasdaq”), as may be necessary by virtue
of the business and operations of the Company or otherwise and do any and all other acts and things that may be necessary or advisable,
in each case, to enable the Holders of Registrable Securities included in such Registration Statement to consummate the disposition of
such Registrable Securities in such jurisdictions; provided, however, that the Company shall not be required to qualify
generally to do business in any jurisdiction where it would not otherwise be required to qualify or take any action to which it would
be subject to general service of process or taxation in any such jurisdiction where it is not then otherwise so subject;

 

    15

date of such Registration Statement;

 

3.1.7
advise each seller of such Registrable Securities, promptly after it shall receive notice or obtain knowledge thereof, of (i) subject
to the MNPI Provisions, any request by the Commission that the Company amend or supplement such Registration Statement or Prospectus or
(ii) the issuance of any stop order by the Commission suspending the effectiveness of such Registration Statement or Prospectus or the
initiation or threatening of any proceeding for such purpose and promptly use its commercially reasonable efforts to amend or supplement
such Registration Statement or Prospectus or prevent the issuance of any stop order or to obtain its withdrawal if such stop order should
be issued, as applicable;

 

3.1.8
at least five Business Days (or, in the case of a Block Trade, at least one day) prior to the filing of any Registration Statement
or Prospectus or any amendment or supplement to such Registration Statement or Prospectus or any document that is to be incorporated by
reference into such Registration Statement or Prospectus, furnish a copy thereof to each seller of such Registrable Securities or its
counsel, including, without limitation, providing, upon request of a Holder, copies promptly upon receipt of any comment letters received
with respect to any such Registration Statement or Prospectus;

 

3.1.9
notify the Holders promptly at any time when a Prospectus relating to such Registration Statement is required to be delivered under
the Securities Act, of the happening of any event as a result of which the Prospectus included in such Registration Statement, as then
in effect, includes a Misstatement, and then correct such Misstatement or include such information as is necessary to comply with law,
in each case as set forth in Section 3.4 hereof;

 

3.1.10
permit a representative of a majority-in-interest of the New Holders, the Underwriters, if any, and any attorney or accountant
retained by such Holders or Underwriter to participate, at each such person’s own expense, in the preparation of any Registration
Statement and cause the Company’s officers, directors and employees to supply all information reasonably requested by any such representative,
Underwriter, attorney or accountant in connection with the Registration; provided, however, that, if requested by the Company,
such representatives or Underwriters shall be required to enter into a confidentiality agreement, in form and substance reasonably satisfactory
to the Company, prior to the release or disclosure of any such information;

 

3.1.11
obtain a “cold comfort” letter (including a bring-down letter dated as of the date the Registrable Securities are delivered
for sale pursuant to such Registration) from the Company’s independent registered public accountants in the event of an Underwritten
Offering that the participating Holders may rely on, in customary form and covering such matters of the type customarily covered by “comfort”
letters as the managing Underwriter may reasonably request, and reasonably satisfactory to a majority-in-interest of the participating
Holders and any Underwriter;

 

    16

     

    

 

3.1.12
on the date the Registrable Securities are delivered for sale pursuant to such Registration, obtain an opinion and negative assurance
letter, dated such date, of counsel representing the Company for the purposes of such Registration, addressed to the Holders, the placement
agent or sales agent, if any, and the Underwriters, if any, covering such legal matters with respect to the Registration in respect of
which such opinion is being given as the Holders, placement agent, sales agent, or Underwriter may reasonably request and as are customarily
included in such opinions and negative assurance letters, and reasonably satisfactory to a majority in interest of the participating Holders
and any Underwriter;

 

3.1.13
in the event of any Underwritten Offering, enter into and perform its obligations under an underwriting agreement, in usual and
customary form, with the managing Underwriter of such offering;

 

3.1.14
otherwise use its commercially reasonable efforts to comply with all applicable rules and regulations of the Commission, and to
make available to its security holders, as soon as reasonably practicable, an earnings statement covering the period of at least 12 months,
beginning with the first day of the Company’s first full calendar quarter after the effective date of the Registration Statement
which satisfies the provisions of Section 11(a) of the Securities Act and the rules and regulations thereunder, including Rule 158 thereunder
(or any successor rule promulgated thereafter by the Commission);

 

3.1.15
if the Registration involves the Registration of Registrable Securities involving gross proceeds in excess of $50,000,000, use
its reasonable efforts to make available senior executives of the Company to participate in customary “road show” presentations
that may be reasonably requested by a majority-in-interest of the participating Holders or the Underwriter in any Underwritten Offering;

 

3.1.16     
if applicable, promptly effect a filing with FINRA pursuant to FINRA Rule 5110 (or successor thereto) with respect to the public
offering contemplated by resales of securities under the Initial Shelf (an “Issuer Filing”), pay the filing
fee required by such Issuer Filing and use its commercially reasonable efforts to complete the Issuer Filing until FINRA issues a letter
confirming that it does not object to the terms of the offering contemplated by the Initial Shelf.

 

3.1.17
cooperate with each Holder that holds Registrable Securities being offered and the Underwriter in any Underwritten Offering with
respect to an applicable Registration Statement, if any, to facilitate the timely (i) preparation and delivery of certificates (not bearing
any restrictive legends) representing Registrable Securities that have been offered and sold pursuant to such Registration Statement,
and enable such certificates to be registered in such names and in such denominations or amounts, as the case may be, or (ii) crediting
of the Registrable Securities that have been offered and sold pursuant to a Registration Statement to the applicable account (or accounts)
with The Depository Trust Company (“DTC”) through its Deposit/Withdrawal At Custodian (“DWAC”)
system, in any such case as such Holder or Underwriter, if any, may reasonably request;

 

3.1.18     
for so long as this Agreement remains effective, use reasonable best effects to (a) cause the Class A Common Stock to be eligible
for clearing through DTC, through its DWAC system; (b) be eligible and participating in the Direct Registration System (DRS) of DTC with
respect to the Class A Common Stock; and (c) ensure that the transfer agent for the Class A Common Stock is a participant in, and that
the Class A Common Stock is eligible for transfer pursuant to, DTC’s Fast Automated Securities Transfer Program (or successor thereto);
and

 

3.1.19
otherwise, in good faith, cooperate reasonably with, and take such customary actions as may reasonably be requested by the Holders
in connection with such Registration.

 

Section 3.2
Registration Expenses. Except as otherwise provided herein, the Registration Expenses of all Registrations shall be borne
by the Company. It is acknowledged by the Holders that the Holders shall bear all incremental selling expenses relating to the sale of
Registrable Securities, such as Underwriters’ commissions and discounts, brokerage fees and, other than as set forth in the definition
of “Registration Expenses,” all reasonable fees and expenses of any legal counsel representing the Holders except as otherwise
provided herein.

 

    17

     

    

 

Section 3.3
Participation in Underwritten Offerings. No Person may participate in any Underwritten Offering for equity securities of
the Company pursuant to a Registration initiated by the Company hereunder unless such Person (a) agrees to sell such Person’s securities
on the basis provided in any underwriting arrangements approved by the Company and (b) completes and executes all customary questionnaires,
powers of attorney, indemnities, lock-up agreements, underwriting agreements and other customary documents as may be reasonably required
under the terms of such underwriting arrangements.

 

Section 3.4
Restrictions on Registration Rights; Suspension of Sales; Adverse Disclosure. If (a) during the period starting with the
date 60 days prior to the Company’s good-faith estimate of the date of the filing of, and ending on a date 120 days after the effective
date of, a Registration Statement in respect of a Company initiated underwritten Registration the Company receives a Demand Registration,
and provided that the Company has delivered written notice to the Holders prior to receipt of a Demand Registration pursuant to subsection
2.2.1 and it continues to actively employ, in good faith, all reasonable efforts to cause the applicable Company-initiated Registration
Statement to become effective, (b) the Holders have requested an Underwritten Registration and the Company and the Holders are unable
to obtain the commitment of the underwriters to firmly underwrite the offer, or (c) in the good faith judgment of the Board such Registration
would be seriously detrimental to the Company and the Board concludes as a result that it is essential to defer the filing of such Registration
Statement at such time, then in each case, the Company shall furnish to such Holders a certificate signed by the Chairman of the Board
stating that in the good-faith judgment of the Board it would be seriously detrimental to the Company for a Registration Statement with
respect to such Demand Registration to be filed in the near future and that it is therefore essential to defer the filing of such Registration
Statement, the Company shall have the right to defer such filing for a period of not more than 60 days. For the avoidance of doubt, the
foregoing ability to defer the filing of a Registration Statement shall not apply to the Company’s obligation to file the Initial
Shelf pursuant to subsection 2.1.1. Upon receipt of written notice from the Company that a Registration Statement or Prospectus
contains a Misstatement, or in the opinion of counsel for the Company it is necessary to supplement or amend such Prospectus to comply
with law, each of the Holders shall forthwith discontinue disposition of Registrable Securities until it has received copies of a supplemented
or amended Prospectus correcting the Misstatement or including the information counsel for the Company instructs is necessary to comply
with law (it being understood that the Company hereby covenants to prepare and file such supplement or amendment as soon as practicable
after the time of such notice such that the Registration Statement or Prospectus, as so amended or supplemented, as applicable, will not
include a Misstatement and complies with law), or until it is advised in writing by the Company that the use of the Prospectus may be
resumed. If the filing, initial effectiveness or continued use of a Registration Statement in respect of any Registration at any time
would require the Company to make an Adverse Disclosure or would require the inclusion in such Registration Statement of financial statements
that are unavailable to the Company for reasons beyond the Company’s control (a “Suspension Event”), the
Company may, subject to the MNPI Provisions, upon giving prompt written notice of such action to the Holders (a “Suspension
Notice”), no later than three Business Days from the date of such Suspension Event, delay the filing or initial effectiveness
of, or suspend use of, such Registration Statement for the shortest period of time required to resolve such issue, but in no event more
than 45 consecutive days, determined in good faith by the Board to be necessary for such purpose; provided that the Company shall
not defer its obligations pursuant to this Section 3.4 more than twice during any 12-month period; provided further, that in no
event shall the Company be entitled to delay or defer the filing or effectiveness of the Initial Shelf pursuant to this Section 3.4.
In the event the Company exercises its rights under the preceding sentence, the Holders agree to suspend, immediately upon their receipt
of the Suspension Notice, their use of the Prospectus relating to any Registration in connection with any sale or offer to sell Registrable
Securities; provided, for the avoidance of doubt, that the foregoing shall not restrict or otherwise affect the consummation of any sale
pursuant to a contract entered into, or order placed, by any Holder prior to delivery of the Suspension Notice. The Company shall immediately
notify the Holders of the expiration of any period during which it exercised its rights under this Section 3.4. The Holders agree
that, except as required by applicable law, the Holders shall treat as confidential the receipt of a Suspension Notice from the Company
under this Section 3.4 (provided that in no event shall such notice disclose the basis for suspension or contain any material nonpublic
information) and shall not disclose the information contained in such written notice without the prior written consent of the Company
until such time as the information contained therein is or becomes public, other than as a result of disclosure by a holder of Registrable
Securities in breach of the terms of this Agreement.

 

    18

     

    

 

Section 3.5
Covenants of the Company.

 

3.5.1
The Company will use its commercially reasonable efforts to make and keep public information available, as those terms are understood
and defined in Rule 144. Without limiting the foregoing, as long as any Holder shall own Registrable Securities (without taking into account
the exclusion of the definition of such term contained in clause (iv) thereof), the Company, at all times while it shall be a reporting
company under the Exchange Act, covenants to file timely all reports required to be filed by the Company after the date hereof pursuant
to Sections 13 or 15(d) of the Exchange Act and to promptly furnish the Holders with true and complete copies of all such filings to the
extent such reports are not available on the SEC’s Electronic Data Gathering, Analysis, and Retrieval (EDGAR) system. The Company
further covenants that it shall take such further action as any Holder may reasonably request, all to the extent required from time to
time to enable such Holder to sell shares of Class A Common Stock held by such Holder without registration under the Securities Act within
the limitation of the exemptions provided by Rule 144 promulgated under the Securities Act (or any successor rule promulgated thereafter
by the Commission), including providing any legal opinions.

 

3.5.2
Other than with respect to any contractual restriction applicable to any Holder, the stock certificates evidencing the Registrable
Securities (without taking into account the exclusion of the definition of such term contained in clause (iv) thereof) (and/or book entries
representing the Registrable Securities) held by each Holder shall not contain or be subject to any legend restricting the transfer thereof
(and the Registrable Securities shall not be subject to any stop transfer or similar instructions or notations): (A) while a Registration
Statement covering the sale or resale of such securities is effective under the Securities Act, if such Holder provides paperwork to the
effect that it will sell, distribute or transfer such securities pursuant to such Registration Statement and the plan of distribution
set forth therein or Rule 144, or (B) if such Holder provides customary paperwork to the effect that it has sold such shares pursuant
to Rule 144, or (C) if such Registrable Securities are eligible for sale under Rule 144 (including Rule 144(i)) as set forth in customary
non-affiliate paperwork provided by such Holder and such non-affiliate Holder agrees to sell or transfer such Registrable Securities pursuant
to Rule 144 or pursuant to a Registration Statement and the plan of distribution set forth therein or (D) if such legend is not required
under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the
Commission) as determined in good faith by counsel to the Company or set forth in a legal opinion delivered by nationally recognized counsel
to the Holder (collectively, the “Unrestricted Conditions”). The Company agrees that at such time as any of
the Unrestricted Conditions is met or such legend is otherwise no longer required it will, no later than two Business Days following the
delivery by a Holder to the Company or the Company’s transfer agent of a certificate representing any Registrable Securities, issued
with a restrictive legend, (or, in the case of Registrable Securities represented by book entries, delivery by a Holder to the Company
or the Company’s transfer agent of a legend removal request) deliver or cause to be delivered to such Holder a certificate or, at
the request of such Holder, deliver or cause to be delivered such Registrable Securities to such Holder by crediting the account of such
Holder’s prime broker with DTC through its Deposit/Withdrawal at Custodian (DWAC) system, in each case, free from all restrictive
and other legends and stop transfer or similar instructions or notations. If any of the Unrestricted Conditions is met at the time of
issuance of any Registrable Securities (e.g., upon exercise of warrants), then such securities shall be issued free of all legends.

 

    19

     

    

 

3.5.3
Notwithstanding anything in this Agreement to the contrary, the Company will not provide any material, nonpublic information to
any Holder without the prior written consent of such Holder, and in the event that the Company believes that a notice or communication
required by this Agreement to be delivered to any Holder contains material, nonpublic information relating to the Company, its securities,
any of its Affiliates or any other Person, the Company shall so indicate to such Holder prior to delivery of such notice or communication,
and such indication shall provide such Holder the means to refuse to receive such notice or communication. No Holder nor any of its Affiliates
or representatives shall have any duty of trust or confidence with respect to, or obligation not to trade in any securities while aware
of, any material, nonpublic information provided to such Holder, Affiliate or representative in violation of this subsection 3.5.3.

 

3.5.4
Notwithstanding the foregoing, to the extent the Company reasonably and in good faith determines that it is necessary to disclose
material non-public information to a Holder in order to comply with its obligations hereunder (a “Necessary Disclosure”),
the Company shall inform counsel to such Holder to the extent such counsel has been identified in writing to the Company in advance of
such determination without disclosing the applicable material non-public information, and the Company and such counsel on behalf of the
applicable Holder shall endeavor to agree upon a process for making such Necessary Disclosure to the applicable Holder or its representatives
that is mutually acceptable to such Holder and the Company (an “Agreed Disclosure Process”). Thereafter, the
Company shall be permitted to make such Necessary Disclosure (only) in accordance with the Agreed Disclosure Process.

 

Section 3.6
Information. The Holders shall provide such information as may reasonably be requested by the Company, or the managing Underwriter,
if any, in connection with the preparation of any Registration Statement, including amendments and supplements thereto, in order to effect
the Registration of any Registrable Securities under the Securities Act pursuant to Article II and in connection with the Company’s
obligation to comply with federal and applicable state securities laws.

but only to the extent that such Misstatement or alleged Misstatement is contained in any information so furnished in writing by such
Holder expressly for use in such Registration Statement or Prospectus; provided, however, that the obligation to indemnify
shall be several, not joint and several, among such Holders of Registrable Securities, and the liability of each such Holder of Registrable
Securities shall be in proportion to and limited to the net proceeds actually received by such Holder from the sale of Registrable Securities
in such offering giving rise to such liability. The Holders of Registrable Securities shall indemnify the Underwriters, their officers,
directors and each Person who controls such Underwriters (within the meaning of the Securities Act) to the same extent as provided in
the foregoing with respect to indemnification of the Company.

 

4.1.3
Any Person entitled to indemnification herein shall (i) give prompt written notice to the indemnifying party of any claim with
respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any Person’s right to
indemnification hereunder to the extent such failure has not materially prejudiced the indemnifying party in defending such claim) and
(ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties
may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory
to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement
made by the indemnified party without its consent (but such consent shall not be unreasonably withheld, conditioned or delayed). An indemnifying
party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more
than one counsel (plus local counsel) for all parties indemnified by such indemnifying party with respect to such claim, unless in the
reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified
parties with respect to such claim. No indemnifying party shall, without the consent of the indemnified party, consent to the entry of
any judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and such money is so paid by
the indemnifying party pursuant to the terms of such settlement) or which settlement does not include as an unconditional term thereof
the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation
or includes any admission as to fault or culpability or failure to act on the part of an indemnified party.

 

4.1.4
The indemnification and contribution provided for under this Agreement shall remain in full force and effect regardless of any
investigation made by or on behalf of the indemnified party or any officer, director, manager, or controlling Person of such indemnified
party and shall survive transfer of securities. The Company and each Holder of Registrable Securities participating in an offering also
agrees to make such provisions as are reasonably requested by any indemnified party for contribution to such party in the event the Company’s
or such Holder’s indemnification is unavailable for any reason.

 

    21

     

    

 

4.1.5
If the indemnification provided under Section 4.1 hereof from the indemnifying party is unavailable or insufficient to hold
harmless an indemnified party in respect of any losses, claims, damages, liabilities and expenses referred to herein, then the indemnifying
party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by the indemnified party as a result
of such losses, claims, damages, liabilities and expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying
party and the indemnified party, as well as any other relevant equitable considerations. The relative fault of the indemnifying party
and indemnified party shall be determined by reference to, among other things, whether any action in question, including any Misstatement
or alleged Misstatement, was made by, or relates to information supplied by, such indemnifying party or indemnified party, and the indemnifying
party’s and indemnified party’s relative intent, knowledge, access to information and opportunity to correct or prevent such
action and the benefits received by the such indemnifying party or indemnified party; provided, however, that the liability
of any Holder under this subsection 4.1.5 shall be limited to the amount of the net proceeds received by such Holder from the sale
of Registrable Securities in such offering giving rise to such liability. The amount paid or payable by a party as a result of the losses
or other liabilities referred to above shall be deemed to include, subject to the limitations set forth in subsections 4.1.1, 4.1.2
and 4.1.3 above, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation
or proceeding. The parties hereto agree that it would not be just and equitable if contribution pursuant to this subsection 4.1.5
were determined by pro rata allocation or by any other method of allocation, which does not take account of the equitable considerations
referred to in this subsection 4.1.5. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Securities Act) shall be entitled to contribution pursuant to this subsection 4.1.5 from any Person who was not guilty of such
fraudulent misrepresentation.

operate as a waiver or preclude the exercise of any other rights or remedies hereunder or thereunder by such party.

to register any securities of the Company for sale or to include such securities of the Company in any Registration filed by the Company
for the sale of securities for its own account or for the account of any other Person. The Company represents, warrants and agrees that
this Agreement supersedes any other registration rights agreement or agreement with similar terms and conditions among the parties thereto,
and in the event of a conflict between any such agreement or agreements and this Agreement, the terms of this Agreement shall prevail.
To the extent the Company grants any Person(s) the right to request the Company or any of its subsidiaries to register any equity securities
of the Company or any of its subsidiaries or any securities convertible or exchangeable into or exercisable for such securities, the Company
shall grant piggyback registration rights to the New Holders in connection therewith.

date as of which all of the Registrable Securities have been sold pursuant to a Registration Statement (but in no event prior to the applicable
