 RE: Subscription Agreement for Founder Shares 

Ladies and Gentlemen: 
 We are pleased to accept
the offer Navigation Capital Holdings IX, LLC, a Delaware limited liability company (the “Subscriber” or “you”), has made to purchase 2,875,000 shares (“Founder Shares”) of the common stock,
$.0001 par value per share (“Common Stock”), of Navigation Capital Acquisition IX, Corp., a Delaware corporation (the “Company”), up to 375,000 Founder Shares of which are subject to complete or partial
forfeiture by you if the underwriters of the initial public offering (“IPO”) of the Company pursuant to the registration statement on Form S-1 (the “Registration
Statement”) do not fully exercise their over-allotment option (the “Over-allotment Option”). The terms (this “Agreement”) on which the Company is willing to sell the Founder Shares to the Subscriber, and
the Company and the Subscriber’s agreements regarding such Founder Shares, are as follows: 
 1. Purchase of Founder Shares. For the sum of
$25,000 (the “Purchase Price”), which the Company acknowledges receiving in cash, the Company hereby sells and issues the Founder Shares to the Subscriber, and the Subscriber hereby purchases the Founder Shares from the Company,
subject to the forfeiture provisions of Section 3 below, on the terms and subject to the conditions set forth in this Agreement. Concurrently with the Subscriber’s execution of this Agreement, the Company shall, at its option, deliver to
the Subscriber a certificate registered in the Subscriber’s name representing the Founder Shares (the “Original Certificate”), or effect such delivery in book-entry form. 

2. Representations, Warranties and Agreements. 

2.1. Subscriber’s Representations, Warranties and Agreements. To induce the Company to issue the Founder Shares to the Subscriber,
the Subscriber hereby represents and warrants to the Company and agrees with the Company as follows: 
 2.1.1. No Government
Recommendation or Approval. The Subscriber understands that no federal or state agency has passed upon or made any recommendation or endorsement of the offering of the Founder Shares. 

2.1.2. No Conflicts. The execution, delivery and performance of this Agreement and the consummation by the Subscriber of the
transactions contemplated hereby do not violate, conflict with or constitute a default under (i) the formation and governing documents of the Subscriber, (ii) any agreement, indenture or instrument to which the Subscriber is a party,
(iii) any law, statute, rule or regulation to which the Subscriber is subject, or (iv) any agreement, order, judgment or decree to which the Subscriber is subject, except in the case of clauses (i) through (iv) that would not
reasonably be expected to have a material adverse effect on the Subscriber. 
 2.1.3. Organization and Authority. The Subscriber 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 you, this Agreement will be a legal, valid and binding agreement of Subscriber, enforceable against Subscriber in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, fraudulent conveyance
or similar laws affecting the enforcement of creditors’ rights generally and subject to general principles of equity (regardless of whether enforcement is sought in a proceeding at law or in equity). 

2.1.4. Experience, Financial Capability and Suitability. Subscriber is: (i) sophisticated in financial matters and is able to
evaluate the risks and benefits of the investment in the Founder Shares and (ii) able to bear the 

 
economic risk of its investment in the Founder Shares for an indefinite period of time because the Founder Shares have not been registered under the Securities Act (as defined below) and
therefore cannot be resold unless subsequently registered under the Securities Act or an exemption from such registration is available. Subscriber is capable of evaluating the merits and risks of its investment in the Company and has the capacity to
protect its own interests. Subscriber must bear the economic risk of this investment until the Founder 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. Subscriber is able to bear the economic risks of an investment in the Founder Shares and to afford a complete loss of Subscriber’s investment in the Founder Shares. 

2.1.5. Access to Information; Independent Investigation. Prior to the execution of this Agreement, the Subscriber has had the
opportunity to ask questions of and receive answers from representatives of the Company concerning an investment in the Company, as well as the finances, operations, business and prospects of the Company, and the opportunity to obtain additional
information to verify the accuracy of all information so obtained. In determining whether to make this investment, Subscriber has relied solely on Subscriber’s own knowledge and understanding of the Company and its business based upon
Subscriber’s own due diligence investigation and the information furnished pursuant to this paragraph. Subscriber understands that no person has been authorized to give any information or to make any representations which were not furnished
pursuant to this Section 2 and Subscriber has not relied on any other representations or information in making its investment decision, whether written or oral, relating to the Company, its operations or its prospects. 

2.1.6. Regulation D Offering. Subscriber represents that it is an “accredited investor” as such term is defined in Rule
501(a) of Regulation D under the Securities Act of 1933, as amended (the “Securities Act”), and acknowledges the sale contemplated hereby is being made in reliance on a private placement exemption applicable to “accredited
investors” or similar exemptions under federal and state law. 
 2.1.7. Investment Purposes. The Subscriber is purchasing the
Founder Shares solely for investment purposes, for the Subscriber’s own account and not for the account or benefit of any other person, and not with a view towards the distribution or dissemination thereof. The Subscriber did not 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. Subscriber understands the Founder Shares are being offered in a transaction not
involving a public offering within the meaning of the Securities Act. Subscriber understands the Founder Shares will be “restricted securities” as defined in Rule 144(a)(3) under the Securities Act and Subscriber understands that the
certificate representing the Founder Shares will contain a legend in respect of such restrictions. If in the future the Subscriber decides to offer, resell, pledge or otherwise transfer the Founder Shares, such Founder Shares may be offered, resold,
pledged or otherwise transferred only in accordance with the provisions of Section 5.1 hereof. Subscriber agrees that if any transfer of its Founder Shares or any interest therein is proposed to be made, as a condition precedent to any such
transfer, Subscriber may be required to deliver to the Company an opinion of counsel satisfactory to the Company. Absent registration or an exemption, the Subscriber agrees not to resell the Founder Shares. Subscriber further acknowledges that
because the Company is a shell company, Rule 144 may not be available to the Subscriber for the resale of the Founder Shares until at least 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 Subscriber in connection with the transactions contemplated by this Agreement. 

2.2. Company’s Representations, Warranties and Agreements. To induce the Subscriber to purchase the Founder Shares, the Company
hereby represents and warrants to the Subscriber and agrees with the Subscriber as follows: 
 2.2.1. Organization and Corporate
Power. The Company is a Delaware corporation, validly existing and in good standing under the laws of Delaware, 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. Upon execution
and delivery by the Company, this Agreement will be a legal, valid and binding agreement of the Company, enforceable against the Company 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). 
 2.2.2. 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 Founder Shares will be
duly and validly issued, fully paid and nonassessable. Upon issuance in accordance with, and payment pursuant to, the terms hereof the Subscriber will have or receive good title to the Founder 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 Founder Shares may be subject which have been notified to the Subscriber in writing, (b) transfer restrictions under federal and
state securities laws, and (c) liens, claims or encumbrances imposed due to the actions of the Subscriber. 
 2.2.4. No Adverse
Actions. There are no actions, suits, investigations or proceedings pending, threatened against or affecting the Company which: (i) seek to restrain, enjoin, prevent the consummation of or otherwise affect the transactions contemplated by
this Agreement or (ii) question the validity or legality of any transactions or seek to recover damages or to obtain other relief in connection with any transactions. 

3. Forfeiture of Founder Shares. 
 3.1.
Partial or No Exercise of the Over-allotment Option. In the event the Over-allotment Option granted to the representative of the underwriters of the IPO is not exercised in full, the Subscriber acknowledges and agrees that it shall forfeit
any and all rights to such number of Founder Shares (up to an aggregate of 1,312,500 Founder Shares and pro rata based upon the percentage of the Over-allotment Option exercised) such that immediately following such forfeiture, the Subscriber (and
all other initial stockholders prior to the IPO plus the holders of any shares of Common Stock to be issued to service providers to the Company by the time that is immediately following the IPO) will own an aggregate number of Founder Shares (not
including shares of Common Stock issuable upon exercise of any warrants or any Common Stock purchased by Subscriber in the IPO or in the aftermarket, any shares of Common Stock underlying units to be issued in a private placement at the time of the
IPO or any shares of Common Stock to be issued to the underwriters at the time of the IPO) equal to 20% of the issued and outstanding Common Stock of the Company immediately following the IPO. 

3.2. Termination of Rights as Stockholder. If any of the Founder Shares are forfeited in accordance with this Section 3, then
after such time the Subscriber (or successor in interest), shall no longer have any rights as a holder of such Founder Shares, and the Company shall take such action as is appropriate to cancel such Founder Shares. 

3.3. Share Certificates. In the event an adjustment to the Original Certificate is required pursuant to this Section 3, then the
Subscriber shall return such Original Certificate to the Company or its designated agent as soon as practicable upon its receipt of notice from the Company advising Subscriber of such adjustment, following which a new certificate (the “New
Certificate”) shall be issued in such amount representing the adjusted number of Founder Shares held by the Subscriber. The New Certificate shall be returned to the Subscriber as soon as practicable. 

4. Waiver of Liquidation Distributions; Redemption Rights. In connection with the Founder Shares purchased pursuant to this Agreement, the Subscriber
hereby waives any and all right, title, interest or claim of any kind in or to any distributions by the Company from the trust account which will be established for the benefit of the Company’s public stockholders and into which substantially
all of the proceeds of the IPO will be deposited (the “Trust Account”), in the event of a liquidation of the Company upon the Company’s failure to timely complete an initial business combination. For purposes of clarity, in the
event the Subscriber purchases Common Stock in the IPO or in the aftermarket, any additional Common Stock so purchased shall be eligible to receive any liquidating distributions by the Company. However, in no event will the Subscriber have the right
to redeem any shares of Common Stock into funds held in the Trust Account upon the successful completion of an initial business combination. 

 5. Restrictions on Transfer. 

5.1. Securities Law Restrictions. In addition to any restrictions to be contained in that certain letter agreement (commonly known as
an “Insider Letter”) to be dated as of the closing of the IPO by and between Subscriber and the Company, Subscriber agrees not to sell, transfer, pledge, hypothecate or otherwise dispose of all or any part of the Founder Shares
unless, prior thereto (a) a registration statement on the appropriate form under the Securities Act and applicable state securities laws with respect to the Founder Shares proposed to be transferred shall then be effective or (b) the
Company has received an opinion from counsel reasonably satisfactory to the Company, that such registration is not required because such transaction is exempt from registration under the Securities Act and the rules promulgated by the Securities and
Exchange Commission thereunder and with all applicable state securities laws. 
 5.2.
Lock-up. Subscriber acknowledges that the Founder Shares will be subject to lock-up provisions (the
“Lock-up”) contained in the Insider Letter. Pursuant to the Insider Letter, Subscriber will agree not to sell, transfer, pledge, hypothecate or otherwise dispose of all or any part of the
Founder Shares until the earlier to occur of: (A) twelve months after the completion of the Company’s initial business combination or (B) subsequent to the Company’s initial business combination, (1) the date on which the
last sale price of the Common Stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within
any 30-trading day period commencing at least150 days after the Company’s initial business combination, or (2) the date on which the Company consummates a liquidation, merger, stock
exchange or other similar transaction after its initial business combination that results in all of its stockholders having the right to exchange their shares of common stock for cash, securities or other property. 

5.3. Restrictive Legends. All certificates representing the Founder Shares shall have endorsed thereon legends substantially as
follows: 
 “THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE
SECURITIES LAWS AND NEITHER THE SECURITIES NOR ANY INTEREST THEREIN MAY BE OFFERED, SOLD, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT OR SUCH LAWS OR AN EXEMPTION FROM
REGISTRATION UNDER SUCH ACT AND SUCH LAWS WHICH, IN THE OPINION OF COUNSEL, IS AVAILABLE.” 
 “THE SECURITIES REPRESENTED BY THIS
CERTIFICATE ARE SUBJECT TO LOCKUP PROVISIONS AND MAY NOT BE OFFERED, SOLD, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED DURING THE TERM OF THE LOCKUP PERIOD.” 

5.4. Additional Founder 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 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 any Founder Shares subject to this
Section 5 or into which such Founder Shares thereby become convertible shall immediately be subject to this Section 5 and Section 3. Appropriate adjustments to reflect the distribution of such securities or property shall be made to
the number or class of Founder Shares subject to this Section 5 and Section 3. 
 5.5. Registration Rights. Subscriber
acknowledges that the Founder Shares are being purchased pursuant to an exemption from the registration requirements of the Securities Act and will become freely tradable only after certain conditions are met or they are registered pursuant to a
registration rights agreement to be entered into with the Company prior to the closing of the IPO. 
 6. Other Agreements. 

6.1. Further Assurances. Subscriber agrees to execute such further instruments and to take such further action as may reasonably be
necessary to carry out the intent of this Agreement. 
 6.2. 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. 
 6.3. Entire Agreement. This Agreement, together with that certain Insider Letter to be entered into
between Subscriber and the Company, substantially in the form to be filed as an exhibit to the Registration Statement, embodies the entire agreement and understanding between the Subscriber and the Company with respect to the subject matter hereof
and supersedes all prior oral or written agreements and understandings relating to the subject matter hereof. No statement, representation, warranty, covenant or agreement of any kind not expressly set forth in this Agreement shall affect, or be
used to interpret, change or restrict, the express terms and provisions of this Agreement. 
 6.4. Modifications and Amendments. The
terms and provisions of this Agreement may be modified or amended only by written agreement executed by all parties hereto. 
 6.5.
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. 
 6.6. 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. 
 6.7.
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. 

6.8. Governing Law, Waiver of Jury Trial. This Agreement and the rights and obligations of the parties hereunder shall be construed in
accordance with and governed by the laws of New York applicable to contracts wholly performed within the borders of such state, without giving effect to the conflict of law principles thereof. The Company (on its behalf and, to the extent permitted
by applicable law, on behalf of its stockholders and affiliates) and the Subscriber hereby irrevocably waive, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to
this Agreement or the transactions contemplated hereby. 
 6.9. Severability. In the event that any court of competent jurisdiction
shall determine that any provision, or any portion thereof, contained in this Agreement shall be unreasonable or unenforceable in any respect, then such provision shall be deemed limited to the extent that such court deems it reasonable and
enforceable, and as so limited shall remain in full force and effect. In the event that such court shall deem any such provision, or portion thereof, wholly unenforceable, the remaining provisions of this Agreement shall nevertheless remain in full
force and effect. 
 6.10. No Waiver of Rights, Powers and Remedies. No failure or delay by a party hereto in exercising any right,
power or remedy under this Agreement, and no course of dealing 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. 

 6.11. Survival of Representations and Warranties. All representations and warranties
made by the parties hereto in this Agreement or in any other agreement, certificate or instrument provided for or contemplated hereby, shall survive the execution and delivery hereof and any investigations made by or on behalf of the parties. 

6.12. 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. 
 6.13. 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. 
 6.14.
Counterparts. This Agreement may be executed in one or more counterparts, all of which when taken together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and
delivered to the other 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. 

6.15. 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. 
 6.16. Mutual Drafting. This Agreement is the joint
product of the Subscriber and the Company and each provision hereof has been subject to the mutual consultation, negotiation and agreement of such parties and shall not be construed for or against any party hereto. 

7. Voting and Redemption of Founder Shares. Subscriber agrees to vote the Founder Shares in favor of an initial business combination that the Company
negotiates and submits for approval to the Company’s stockholders and shall not seek redemption with respect to such Founder Shares. Additionally, the Subscriber agrees not to redeem any Founder 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. 
 8.
Indemnification. Each party shall indemnify the other against any loss, cost or damages (including reasonable and documented attorneys’ fees and expenses) incurred as a result of such party’s breach of any representation, warranty,
covenant or agreement in this Agreement.

REGISTRATIONS AND OFFERINGS

 

2.1          Shelf
Registration.

 

2.1.1        Filing.
The Company shall file within 45 days of the Closing Date, and use commercially reasonable efforts to cause to be declared effective
as soon as practicable thereafter, a Registration Statement for a Shelf Registration on Form S-1 (the “Form S-1
Shelf”) or, if the Company is eligible to use a Registration Statement on Form S-3, a Shelf Registration on
Form S-3 (the “Form S-3 Shelf”), in each case, covering the resale of all the Registrable
Securities (determined as of two business days prior to such filing) on a delayed or continuous basis. Such Shelf shall provide
for the resale of the Registrable Securities included therein pursuant to any method or combination of methods legally available
to, and requested by, any Holder named therein. The Company shall maintain a Shelf in accordance with the terms hereof, and shall
prepare and file with the SEC such amendments, including post-effective amendments, and supplements as may be necessary to keep
a Shelf continuously effective, available for use and in compliance with the provisions of the Securities Act until such time
as there are no longer any Registrable Securities. In the event the Company files a Form S-1 Shelf, the Company shall use
its commercially reasonable efforts to convert the Form S-1 Shelf (and any Subsequent Shelf Registration) to a Form S-3
Shelf as soon as practicable after the Company is eligible to use Form S-3.

 

    	 	5	 

     

    

 

2.1.2        Subsequent
Shelf Registration. If any Shelf ceases to be effective under the Securities Act for any reason at any time while Registrable
Securities are still outstanding, the Company shall, subject to Section 3.4, use its commercially reasonable efforts
to as promptly as is reasonably practicable cause such Shelf to again become effective under the Securities Act (including obtaining
the prompt withdrawal of any order suspending the effectiveness of such Shelf), and shall use its commercially reasonable efforts
to as promptly as is reasonably practicable amend such Shelf in a manner reasonably expected to result in the withdrawal of any
order suspending the effectiveness of such Shelf or file an additional registration statement as a Shelf Registration (a “Subsequent
Shelf Registration”) registering the resale of all Registrable Securities (determined as of two business days prior
to such filing), and pursuant to any method or combination of methods legally available to, and requested by, any Holder named
therein. If a Subsequent Shelf Registration is filed, the Company shall use its commercially reasonable efforts to (i) cause
such Subsequent Shelf Registration to become effective under the Securities Act as promptly as is reasonably practicable after
the filing thereof (it being agreed that the Subsequent Shelf Registration shall be an automatic shelf registration statement
(as defined in Rule 405 promulgated under the Securities Act) if the Company is a well-known seasoned issuer (as defined
in Rule 405 promulgated under the Securities Act) at the most recent applicable eligibility determination date) and (ii) keep
such Subsequent Shelf Registration continuously effective, available for use and in compliance with the provisions of the Securities
Act until such time as there are no longer any Registrable Securities. Any such Subsequent Shelf Registration shall be on Form S-3
to the extent that the Company is eligible to use such form. Otherwise, such Subsequent Shelf Registration shall be on another
appropriate form.

 

2.1.3        Additional
Registerable Securities. In the event that any Holder holds Registrable Securities that are not registered for resale on a
delayed or continuous basis, the Company, upon request of a DM Equityholder or a Sponsor Equityholder that holds at least five
(5.0%) percent of the Registrable Securities, shall promptly use its commercially reasonable efforts to cause the resale of such
Registrable Securities to be covered by either, at the Company’s option, the Shelf (including by means of a post-effective
amendment) or a Subsequent Shelf Registration and cause the same to become effective as soon as practicable after such filing
and such Shelf or Subsequent Shelf Registration shall be subject to the terms hereof; provided, however, that the
Company shall only be required to cause such Registrable Securities to be so covered twice per calendar year for the DM Equityholders,
on the one hand, and the Sponsor Equityholders, on the other hand.

 

2.1.4        Requests
for Underwritten Shelf Takedowns. At any time and from time to time when an effective Shelf is on file with the Commission,
any DM Equityholder or Sponsor Equityholder (any of the DM Equityholders or the Sponsor Equityholders being, in such case, a “Demanding
Holder”) may request to sell all or any portion of its Registrable Securities in an Underwritten Offering or other
coordinated offering that is registered pursuant to the Shelf (each, an “Underwritten Shelf Takedown”);
provided that the Company shall only be obligated to effect an Underwritten Shelf Takedown if such offering shall include
Registrable Securities proposed to be sold by the Demanding Holder with a total offering price reasonably expected to exceed,
in the aggregate, $75 million (the “Minimum Takedown Threshold”). All requests for Underwritten Shelf
Takedowns shall be made by giving written notice to the Company, which shall specify the approximate number of Registrable Securities
proposed to be sold in the Underwritten Shelf Takedown. Subject to Section 2.4.4, the Company shall have the right
to select the Underwriters for such offering (which shall consist of one or more reputable nationally recognized investment banks),
subject to the initial Demanding Holder’s prior approval (which shall not be unreasonably withheld, conditioned or delayed).
The DM Equityholders, on the one hand, and the Sponsor Equityholders, on the other hand, may each demand not more than two (2) Underwritten
Shelf Takedowns pursuant to this Section 2.1.4 in any 12-month period. Notwithstanding anything to the contrary in this Agreement,
the Company may effect any Underwritten Offering pursuant to any then effective Registration Statement, including a Form S-3,
that is then available for such offering.

 

    	 	6	 

     

    

 

2.1.5        Reduction
of Underwritten Offering. If the managing Underwriter or Underwriters in an Underwritten Shelf Takedown, in good faith, advises
the Company, the Demanding Holders and the Holders requesting piggy back rights pursuant to this Agreement with respect to such
Underwritten Shelf Takedown (the “Requesting Holders”) (if any) in writing that 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 shares of Common Stock or other equity securities that the Company desires to sell and all other shares of Common
Stock or other equity securities, if any, that have been requested to be sold in such Underwritten Offering pursuant to separate
written contractual piggy-back registration rights held by any other stockholders, exceeds the maximum dollar amount or maximum
number of equity securities that can be sold in the 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, before including any shares of Common Stock or other equity securities proposed to be sold by Company
or by other holders of Common Stock or other equity securities, the Registrable Securities of the Demanding Holders and the Requesting
Holders (if any) (pro rata based on the respective number of Registrable Securities that each Demanding Holder and Requesting
Holder (if any) has requested be included in such Underwritten Shelf Takedown and the aggregate number of Registrable Securities
that the Demanding Holders and Requesting Holders have requested be included in such Underwritten Shelf Takedown) that can be
sold without exceeding the Maximum Number of Securities. To facilitate the allocation of Registrable Securities in accordance
with the above provisions, the Company or the Underwriters may round the number of shares allocated to any Holder to the nearest
100 shares. The Company shall not be required to include any Registrable Securities in such Underwritten Shelf Takedown unless
the Holders accept the terms of the underwriting as agreed upon between the Company and its Underwriters.

 

2.1.6        Withdrawal.
Prior to the filing of the applicable “red herring” prospectus or prospectus supplement used for marketing such Underwritten
Shelf Takedown, a majority-in-interest of the Demanding Holders initiating an Underwritten Shelf Takedown shall have the right
to withdraw from such Underwritten Shelf Takedown for any or no reason whatsoever upon written notification (a “Withdrawal
Notice”) to the Company and the Underwriter or Underwriters (if any) of their intention to withdraw from such Shelf
Takedown; provided that any DM Equityholder or Sponsor Equityholder may elect to have the Company continue an Underwritten
Shelf Takedown if the Minimum Takedown Threshold would still be satisfied by the Registrable Securities proposed to be sold in
the Underwritten Shelf Takedown by the DM Equityholders, the Sponsor Equityholders or any of their respective Permitted Transferees,
as applicable. If withdrawn, a demand for an Underwritten Shelf Takedown shall constitute a demand for an Underwritten Shelf Takedown
for purposes of Section 2.1.4, unless either (i) the Demanding Holder has not previously withdrawn any Underwritten
Shelf Takedown or (ii) the Holder reimburses the Company for all Registration Expenses with respect to such Underwritten
Shelf Takedown; provided that, if a DM Equityholder or a Sponsor Equityholder elects to continue an Underwritten Shelf
Takedown pursuant to the proviso in the immediately preceding sentence, such Underwritten Shelf Takedown shall instead count as
an Underwritten Shelf Takedown demanded by the DM Equityholders or the Sponsor Equityholders, as applicable, for purposes of Section 2.1.4.
Following the receipt of any Withdrawal Notice, the Company shall promptly forward such Withdrawal Notice to any other Holders
that had elected to participate in such Shelf Takedown. Notwithstanding anything to the contrary in this Agreement, the Company
shall be responsible for the Registration Expenses incurred in connection with a Shelf Takedown prior to its withdrawal under
this Section 2.1.6, other than if a Demanding Holder elects to pay such Registration Expenses pursuant to clause (ii) of
the second sentence of this Section 2.1.6.

2.2          Piggyback
Registration.

 

2.2.1        Piggyback
Rights. Subject to Section 2.4.3, if the Company or any Holder proposes to conduct a registered offering of, or
if the Company proposes to file a Registration Statement under the Securities Act with respect to the Registration 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, an Underwritten Shelf Takedown pursuant to Section 2.1 hereof), other than a Registration Statement
(or any registered offering with respect thereto) (i) filed in connection with any employee stock option or other benefit
plan, (ii) pursuant to a Registration Statement on Form S-4 (or similar form that relates to a transaction subject to
Rule 145 under the Securities Act or any successor rule thereto), (iii) for an offering of debt that is convertible
into equity securities of the Company or, (iv) for a dividend reinvestment plan or (v) for a rights offering, then the
Company shall give written notice of such proposed offering to all of the Holders of Registrable Securities as soon as practicable
but not less than ten (10) days before the anticipated filing date of such Registration Statement or, in the case of an Underwritten
Offering pursuant to a Shelf Registration, the applicable “red herring” prospectus or prospectus supplement used for
marketing such offering, which notice shall (A) describe the amount and type of securities to be included in such offering,
the intended method(s) of distribution, and the name of the proposed managing Underwriter or Underwriters, if any, in such
offering, and (B) offer to all of the Holders of Registrable Securities the opportunity to include in such registered offering
such number of Registrable Securities as such Holders may request in writing within five (5) days after receipt of such written
notice (such registered offering, a “Piggyback Registration”). Subject to Section 2.2.2,
the Company shall, in good faith, cause such Registrable Securities to be included in such Piggyback Registration and, if applicable,
shall use its commercially reasonable efforts to cause the managing Underwriter or Underwriters of such Piggyback Registration
to permit the Registrable Securities requested by the Holders pursuant to this Section 2.2.1 to be included therein
on the same terms and conditions as any similar securities of the Company included in such registered offering and to permit the
sale or other disposition of such Registrable Securities in accordance with the intended method(s) of distribution thereof.
The inclusion of any Holder’s Registrable Securities in a Piggyback Registration shall be subject to such Holder’s
agreement to enter into an underwriting agreement in customary form with the Underwriter(s) selected for such Underwritten
Offering.

 

2.2.2        Reduction
of Piggyback Registration. If the managing Underwriter or Underwriters in an Underwritten Offering that is to be a Piggyback

offering has been demanded pursuant to separate written contractual arrangements with persons or entities other than the Holders
of Registrable Securities hereunder, (ii) the Registrable Securities as to which registration has been requested pursuant
to Section 2.2 hereof, and (iii) the shares of Common Stock or other equity securities, if any, as to which Registration
or a registered offering 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:

 

(a)            If
the Registration or registered offering is undertaken for the Company’s account, the Company shall include in any such Registration
or registered offering (A) first, the shares of 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 Section 2.2.1, pro rata, based on the respective number
of Registrable Securities that each Holder has requested be included in such Underwritten Offering and the aggregate number of
Registrable Securities that the Holders have requested to be included in such Underwritten Offering, 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 shares of Common Stock or other equity securities, if any, as to which

(b)            If

Securities, then the Company shall include in any such Registration or registered offering (A) first, the shares of 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 Section 2.2.1, pro rata, based on the respective number
of Registrable Securities that each Holder has requested be included in such Underwritten Offering and the aggregate number of
Registrable Securities that the Holders have requested to be included in such Underwritten Offering, 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 shares of Common Stock or other equity securities that the Company desires to
sell, 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 shares of 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;
and

 

(c)            If
the Registration or registered offering is pursuant to a request by Holder(s) of Registrable Securities pursuant to Section 2.1
hereof, then the Company shall include in any such Registration or registered offering securities pursuant to Section 2.1.5.

 

2.2.3        Piggyback
Registration Withdrawal. Any Holder of Registrable Securities (other than a Demanding Holder, whose right to withdrawal from

to withdraw from 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 from such Piggyback Registration prior to the effectiveness
of the Registration Statement filed with the Commission with respect to such Piggyback Registration or, in the case of a Piggyback
Registration pursuant to a Shelf Registration, the filing of the applicable “red herring” prospectus or prospectus
supplement with respect to such Piggyback Registration used for marketing such transaction. 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 (which, in no circumstance,
shall include the Shelf) at any time prior to the effectiveness of such Registration Statement. Notwithstanding anything to the
contrary in this Agreement (other than Section 2.1.6), the Company shall be responsible for the Registration Expenses
incurred in connection with the Piggyback Registration prior to its withdrawal under this Section 2.2.3.

 

2.2.4        Unlimited
Piggyback Registration Rights. For purposes of clarity, subject to Section 2.1.6, any Piggyback Registration effected
pursuant to Section 2.2 hereof shall not be counted as a demand for an Underwritten Shelf Takedown under Section 2.1.4
hereof.

 

    	 	9	 

     

    

 

2.3            Market
Stand-off. In connection with any Underwritten Offering of equity securities of the Company (other than a Block Trade), each
Holder given an opportunity to participate in the Underwritten Offering pursuant to the terms of this Agreement agrees that it
shall not Transfer any shares of 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 Common Stock, except in the event the Underwriters managing the offering otherwise agree by written consent. Each Holder 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).

 

2.4           Block
Trades.

 

2.4.1        Notwithstanding
the foregoing, at any time and from time to time when an effective Shelf is on file with the Commission and effective, if a Demanding
Holder wishes to engage in an underwritten or other coordinated registered offering not involving a “roadshow,” an
offer commonly known as a “block trade” (a “Block Trade”), with a total offering price reasonably
expected to exceed, in the aggregate, either (x) $100 million or (y) all remaining Registrable Securities held by the
Demanding Holder, then notwithstanding the time periods provided for in Section 2.1.4, such Demanding Holder need
only to notify the Company of the Block Trade at least five (5) 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 representing a majority of the Registrable Securities wishing to engage in the Block Trade shall
use commercially reasonable efforts to work with the Company and any Underwriters prior to making such request in order to facilitate
preparation of the registration statement, prospectus and other offering documentation related to the Block Trade.

to the filing of the applicable “red herring” prospectus or prospectus supplement used in connection with a Block
Trade, a majority-in-interest of the Demanding Holders initiating such Block Trade shall have the right to submit a Withdrawal
Notice to the Company and the Underwriter or Underwriters (if any) of their intention to withdraw from such Block Trade. Notwithstanding
anything to the contrary in this Agreement, the Company shall be responsible for the Registration Expenses incurred in connection
with a block trade prior to its withdrawal under this Section 2.4.2.

 

2.4.3        Notwithstanding
anything to the contrary in this Agreement, Section 2.2 hereof shall not apply to a Block Trade initiated by a Demanding
Holder pursuant to this Agreement.

to participate, at each such person’s own expense, in the preparation of the 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 such representatives or Underwriters
agree to confidentiality arrangements reasonably satisfactory to the Company, prior to the release or disclosure of any such information;

 

3.1.11      obtain
a “comfort” letter from the Company’s independent registered public accountants in the event of an Underwritten
Offering or other coordinated offering that is registered pursuant to a Registration Statement, in customary form and covering
such matters of the type customarily covered by “comfort” letters as the managing Underwriter or other similar type
of sales agent or placement agent may reasonably request, and reasonably satisfactory to a majority-in-interest of the participating
Holders;

 

3.1.12      on
the date the Registrable Securities are delivered for sale pursuant to such Registration, obtain an opinion, 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;

 

3.1.13      in
the event of any Underwritten Offering or other coordinated offering that is registered pursuant to a Registration Statement,
enter into and perform its obligations under an underwriting agreement, sales agreement or placement agreement, in usual and customary
form, with the managing Underwriter, sales agent or placement agent of such offering;

 

3.1.14      make
available to its security holders, as soon as reasonably practicable, an earnings statement covering the period of at least twelve
(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 Rule 158 thereunder (or any
successor rule then in effect);

 

3.1.15      if
the Registration involves the Registration of Registrable Securities involving gross proceeds in excess of $50 million with respect
to an Underwritten Offering pursuant to Section 2.1.4, 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 the Underwriter
in such Underwritten Offering; and

 

3.1.16      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.

 

    	 	12	 

     

    

 

Notwithstanding the foregoing, the Company
shall not be required to provide any documents or information to an Underwriter or other sales agent or placement agent if such
Underwriter or other sales agent or placement agent has not then been named with respect to the applicable Underwritten Offering
or other coordinated offering that is registered pursuant to a Registration Statement.

 

3.2            Registration
Expenses. 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’
or agents’ commissions and discounts, brokerage fees, Underwriter marketing costs and, other than as set forth in the definition
of “Registration Expenses,” all reasonable fees and expenses of any legal counsel representing the Holders.

 

3.3            Requirements
for Participation in Registration Statement Underwritten Offerings. Notwithstanding anything in this Agreement to the contrary,
if any Holder does not provide the Company with its requested Holder Information, the Company may exclude such Holder’s
Registrable Securities from the applicable Registration Statement or Prospectus if the Company determines, based on the advice
of counsel, that such information is necessary to effect the registration and such Holder continues thereafter to withhold such
information. No person may participate in any Underwritten Offering or other coordinated offering for equity securities of the
Company pursuant to a Registration initiated by the Company hereunder unless such person (i) agrees to sell such person’s
securities on the basis provided in any arrangements approved by the Company and (ii) completes and executes all customary
questionnaires, powers of attorney, indemnities, lock-up agreements, underwriting or other agreements and other customary documents
as may be reasonably required under the terms of such arrangements. The exclusion of a Holder’s Registrable Securities as
a result of this Section 3.3 shall not affect the registration of the other Registrable Securities to be included
in such Registration.

 

3.4          Suspension
of Sales; Adverse Disclosure; Restrictions on Registration Rights.

 

3.4.1        Upon
receipt of written notice from the Company that a Registration Statement or Prospectus contains a Misstatement, 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 (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), or until it is advised in writing by the Company that the use of the Prospectus
may be resumed.

 

3.4.2        If
the filing, initial effectiveness or continued use of a Registration Statement in respect of any Registration at any time would
(a) require the Company to make an Adverse Disclosure, (b) require the inclusion in such Registration Statement of financial
statements that are unavailable to the Company for reasons beyond the Company’s control, or (c) in the good faith judgment
of the majority of the Board such Registration, be seriously detrimental to the Company and the majority of the Board concludes
as a result that it is essential to defer such filing, initial effectiveness or continued use at such time, the Company may, upon
giving prompt written notice of such action to the Holders, delay the filing or initial effectiveness of, or suspend use of, such
Registration Statement for the shortest period of time determined in good faith by the Company to be necessary for such purpose.
In the event the Company exercises its rights under this Section 3.4.2, the Holders agree to suspend, immediately
upon their receipt of the notice referred to above, their use of the Prospectus relating to any Registration in connection with
any sale or offer to sell Registrable Securities.

 

3.4.3        (a) During
the period starting with the date sixty (60) days prior to the Company’s good faith estimate of the date of the filing of,
and ending on a date one hundred and twenty (120) days after the effective date of, a Company-initiated Registration and provided
that the Company continues to actively employ, in good faith, all reasonable efforts to maintain the effectiveness of the applicable
Shelf Registration Statement, or (b) if, pursuant to Section 2.1.4, Holders have requested an Underwritten
Shelf Takedown and the Company and such Holders are unable to obtain the commitment of underwriters to firmly underwrite such
offering, the Company may, upon giving prompt written notice of such action to the Holders, delay any other registered offering
pursuant to Section 2.1.4 or 2.4.

 

    	 	13	 

     

    

 

3.5            Reporting
Obligations. As long as any Holder shall own Registrable Securities, the Company, at all times while it shall be a reporting
company under the Exchange Act, covenants to file timely (or obtain extensions in respect thereof and file within the applicable
grace period) all reports required to be filed by the Company after the date hereof pursuant to Sections 13(a) or 15(d) of
the Exchange Act and to promptly furnish the Holders with true and complete copies of all such filings; provided that any
documents publicly filed or furnished with the Commission pursuant to the Electronic Data Gathering, Analysis and Retrieval System
shall be deemed to have been furnished or delivered to the Holders pursuant to this Section 3.5. 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 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 then
in effect). Upon the request of any Holder, the Company shall deliver to such Holder a written certification of a duly authorized
officer as to whether it has complied with such requirements.

 

Article IV

INDEMNIFICATION AND CONTRIBUTION

 

4.1          Indemnification.

 

4.1.1        The
Company agrees to indemnify, to the extent permitted by law, each Holder of Registrable Securities, its officers, directors and
agents and each person who controls such Holder (within the meaning of the Securities Act) against all losses, claims, damages,
liabilities and out-of-pocket expenses (including without limitation reasonable outside attorneys’ fees) resulting from
any untrue or alleged untrue statement of material fact contained in any Registration Statement, Prospectus or preliminary Prospectus
or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein
or necessary to make the statements therein not misleading, except insofar as the same are caused by or contained in any information
or affidavit so furnished in writing to the Company by such Holder expressly for use therein.

 

4.1.2        In
connection with any Registration Statement in which a Holder of Registrable Securities is participating, such Holder shall furnish
to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such
Registration Statement or Prospectus (the “Holder Information”) and, to the extent permitted by law,
shall indemnify the Company, its directors, officers and agents and each person who controls the Company (within the meaning of
the Securities Act) against all losses, claims, damages, liabilities and out-of-pocket expenses (including without limitation
reasonable outside attorneys’ fees) resulting from any untrue or alleged untrue statement of material fact contained in
any Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission
or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading,
but only to the extent that such untrue statement or omission is contained in any information or affidavit so furnished in writing
by such Holder expressly for use therein; 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 received by such Holder from the sale of Registrable Securities pursuant
to such Registration Statement. 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.

 

    	 	14	 

     

    

 

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) 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). 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 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.

 

4.1.4        The
indemnification 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 or controlling person of such indemnified party and shall survive
the 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.

 

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 out-of-pocket 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 out-of-pocket 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 untrue or alleged untrue statement of a material fact or
omission or alleged omission to state a material fact, 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; provided, however, that the liability of any Holder under this
Section 4.1.5 shall be limited to the amount of the net proceeds received by such Holder 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 Sections 4.1.1, 4.1.2 and 4.1.3 above, any
legal or other fees, charges or out-of-pocket 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 Section 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 Section 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 Section 4.1.5
from any person who was not guilty of such fraudulent misrepresentation.

Agreement and the rights, duties and obligations of the Company hereunder may not be assigned or delegated by the Company in whole
or in part.

 

5.2.2        A
Holder may assign or delegate such Holder’s rights, duties or obligations under this Agreement, in whole or in part, to
any person to whom it transfers Registrable Securities; provided that such Registrable Securities remain Registrable Securities
following such transfer and such person agrees to become bound by the terms and provisions of this Agreement.

 

5.2.3        No
assignment by any party hereto of such party’s rights, duties and obligations hereunder shall be binding upon or obligate
the Company unless and until the Company shall have received (i) written notice of such assignment as provided in Section 5.1
hereof and (ii) the written agreement of the assignee, in a form reasonably satisfactory to the Company, to be bound by the
terms and provisions of this Agreement (which may be accomplished by an addendum or certificate of joinder to this Agreement).

 

5.2.4        Subject
to the foregoing, this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective permitted
successors and assigns. Any attempted assignment in violation of the terms of this Section 5.02 shall be null and void, ab
initio.

 

5.2.5        This
Agreement shall not confer any rights or benefits on any persons that are not parties hereto, other than as expressly set forth
in this Agreement and Section 5.2 hereof.

 

5.3          Captions;
Counterparts. The captions in this Agreement are for convenience only and shall not be considered a part of or affect the
construction or interpretation of any provision of this Agreement. This Agreement may be executed in two (2) or more counterparts,
each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

 

5.4          Governing
Law. This Agreement, and all claims or causes of action based upon, arising out of,
or related to this Agreement or the transactions contemplated hereby, shall be governed by, and construed in accordance with,
the Laws of the State of Delaware, without giving effect to principles or rules of conflict of laws to the extent such principles
or rules would require or permit the application of Laws of another jurisdiction.

 

    	 	16	 

     

    

 

5.5          Jurisdiction;
Waiver of Jury Trial.

 

5.5.1        Any
Action based upon, arising out of or related to this Agreement, or the transactions contemplated hereby, shall be brought in the
Court of Chancery of the State of Delaware or, if such court declines to exercise jurisdiction, any federal or state court located
in New York County, New York, and each of the parties irrevocably submits to the exclusive jurisdiction of each such court in
any such Action, waives any objection it may now or hereafter have to personal jurisdiction, venue or to convenience of forum,
agrees that all claims in respect of the Action shall be heard and determined only in any such court, and agrees not to bring
any Action arising out of or relating to this Agreement or the transactions contemplated hereby in any other court. Nothing herein
contained shall be deemed to affect the right of any party to serve process in any manner permitted by Law, or to commence legal
proceedings or otherwise proceed against any other party in any other jurisdiction, in each case, to enforce judgments obtained
in any Action brought pursuant to this Section 5.5.1.

 

5.5.2        EACH
OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY ACTION BASED UPON, ARISING OUT OF OR
RELATED TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

 

5.6          Amendments
and Modifications. Upon the written consent of (a) the Company and (b) the Holders of a majority of the total Registrable
Securities, compliance with any of the provisions, covenants and conditions set forth in this Agreement may be waived, or any
of such provisions, covenants or conditions may be amended or modified; provided, however, that in the event any
such waiver, amendment or modification would be adverse in any material respect to the material rights or obligations hereunder
of a Holder of at least five (5.0%) percent of the Registrable Securities, the written consent of such Holder will also be required;
provided further that in the event any such waiver, amendment or modification would be disproportionate and adverse in
any material respect to the material rights or obligations hereunder of a Holder, the written consent of such Holder will also
be required. No course of dealing between any Holder or the Company and any other party hereto or any failure or delay on the
part of a Holder or the Company in exercising any rights or remedies under this Agreement shall operate as a waiver of any rights
or remedies of any Holder or the Company. No single or partial exercise of any rights or remedies under this Agreement by a party
shall operate as a waiver or preclude the exercise of any other rights or remedies hereunder or thereunder by such party.

or similar rights of the Holders with respect to any shares or securities of Trine or Legacy DM granted under any other agreement,

Ltd., and any of such preexisting registration, qualification or similar rights and such agreements shall be terminated and of
no further force and effect.

 

5.8         Term.

AMENDMENT NO. 1

TO

AMENDED AND RESTATED REGISTRATION RIGHTS AGREEMENT

 

THIS AMENDMENT NO. 1 TO AMENDED
AND RESTATED REGISTRATION RIGHTS AGREEMENT (this “Amendment”) is effective as of June 30, 2021 by and among Desktop
Metal, Inc., a Delaware corporation (the “Company”), and the undersigned Holders.

 

WHEREAS, the Company
and the Holders are parties to that certain Amended and Restated Registration Rights Agreement, dated as of August 26, 2020, by and
among the Company and the parties thereto (the “RRA”);

 

WHEREAS, the RRA may
be amended upon the written consent of (a) the Company and (b) the Holders of a majority of the total Registrable Securities
(the “Required Holders”); and

 

WHEREAS, the Company
and the undersigned Holders, constituting the Required Holders, desire to amend the RRA as set forth in this Amendment.

 

NOW, THEREFORE, in
consideration of the mutual promises and covenants contained in this Amendment and for other good and valuable consideration, the receipt
and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

 

1.1            Section 2.2.1
of the RRA is hereby amended and restated to read in its entirety as follows:

 

“2.2.1 Piggyback
Rights. Subject to Section 2.4.3, if the Company or any Holder proposes to conduct a registered offering of, or if the
Company proposes to file a Registration Statement under the Securities Act with respect to the Registration 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, an Underwritten
Shelf Takedown pursuant to Section 2.1 hereof), other than a Registration Statement (or any registered offering with respect thereto)
(i) filed in connection with any employee stock option or other benefit plan, (ii) pursuant to a Registration Statement on Form S-4
(or similar form that relates to a transaction subject to Rule 145 under the Securities Act or any successor rule thereto),
(iii) for an offering of debt that is convertible into equity securities of the Company, (iv) for a dividend reinvestment plan,
(v) for a rights offering, or (vi) to register the resale by selling stockholders of equity securities of the Company issued
by the Company as consideration in an acquisition approved by the Board, then the Company shall give written notice of such proposed offering
to all of the Holders of Registrable Securities as soon as practicable but not less than ten (10) days before the anticipated filing
date of such Registration Statement or, in the case of an Underwritten Offering pursuant to a Shelf Registration, the applicable “red
herring” prospectus or prospectus supplement used for marketing such offering, which notice shall (A) describe the amount and
type of securities to be included in such offering, the intended method(s) of distribution, and the name of the proposed managing
Underwriter or Underwriters, if any, in such offering, and (B) offer to all of the Holders of Registrable Securities the opportunity
to include in such registered offering such number of Registrable Securities as such Holders may request in writing within five (5) days
after receipt of such written notice (such registered offering, a “Piggyback Registration”). Subject to Section 2.2.2,
the Company shall, in good faith, cause such Registrable Securities to be included in such Piggyback Registration and, if applicable,
shall use its commercially reasonable efforts to cause the managing Underwriter or Underwriters of such Piggyback Registration to permit
the Registrable Securities requested by the Holders pursuant to this Section 2.2.1 to be included therein on the same terms and conditions
as any similar securities of the Company included in such registered offering and to permit the sale or other disposition of such Registrable
Securities in accordance with the intended method(s) of distribution thereof. The inclusion of any Holder’s Registrable Securities
in a Piggyback Registration shall be subject to such Holder’s agreement to enter into an underwriting agreement in customary form
with the Underwriter(s) selected for such Underwritten Offering.”

 

     

     

    

 

2.            Definitions.
Capitalized terms used herein but not otherwise defined herein shall have the meanings ascribed to them in the RRA.

 

3.            Continued
Validity of RRA. Except as amended hereby, the RRA shall continue in full force and effect as originally constituted and is ratified
and affirmed by the parties hereto.

 

4.            Governing
Law. This Amendment and all claims or causes of action based upon, arising out of, or related to this Amendment or the transactions
contemplated hereby, shall be governed by, and construed in accordance with, the laws of the State of Delaware, without giving effect
to principles or rules of conflict of laws to the extent such principles or rules would require or permit the application of
laws of another jurisdiction.

 

5.            Counterparts;
Facsimile. This Amendment may be executed in two or more counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument. Counterparts may be delivered via facsimile, electronic mail (including pdf or
any electronic signature complying with the U.S. federal ESIGN Act of 2000, e.g., www.docusign.com) or other transmission method
and any counterpart so delivered shall be deemed to have been duly and validly delivered and be valid and effective for all purposes.
