RE: Surrender
and Potential Forfeiture of Parent Class B Common Stock

 

Reference is made to
that certain Agreement and Plan of Merger (the “Merger Agreement”), to be dated as of the date hereof, by and
among Momentus Inc., a Delaware corporation (the “Company”), Stable Road Acquisition Corp., a Delaware corporation
(“Parent”), Project Marvel First Merger Sub, Inc., a Delaware corporation and a direct, wholly-owned subsidiary
of Parent, and Project Marvel Second Merger Sub, LLC, a Delaware limited liability company and a direct, wholly-owned subsidiary
of Parent. This letter agreement (this “Letter Agreement”) is being entered into and delivered by Parent, SRC-NI
Holdings, LLC, a Delaware limited liability company (“Sponsor”), and SRAC PIPE Partners LLC, a Delaware limited
liability company (“SRAC Partners”) in connection with the transactions contemplated by the Merger Agreement.
Capitalized terms used but not otherwise defined herein shall have the meanings ascribed to such terms in the Merger Agreement.

 

In consideration of
the foregoing and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Parent
and Sponsor hereby agree as follows:

 

		1.	Sponsor represents and warrants that (i) it holds 4,136,029 of the issued and outstanding shares
of Class B common stock, par value $0.0001 per share, of Parent (the “Parent Class B Common Stock”) and (ii)
SRAC Partners holds 176,471 of the issued and outstanding shares of Parent Class B Common Stock, as of the date of this Letter
Agreement. As of the date hereof, there are 4,312,500 shares of Parent Class B Common Stock issued and outstanding.

 

		2.	Subject to the satisfaction or waiver of each of the conditions to Closing set forth in Sections
8.1 and 8.3 of the Merger Agreement, immediately prior to and conditioned upon the consummation of the Closing, Sponsor shall surrender
1,437,500 shares of Parent Class B Common Stock (the “Sponsor Contingent Closing Shares”) if, and only if, (i)
the amount in the Trust Account (for the avoidance of doubt, prior to giving effect to the Parent Stockholder Redemptions and the
payment of any Parent Transaction Costs), minus (ii) the aggregate amount of cash proceeds that will be required to satisfy
the Parent Stockholder Redemptions (the result of clauses (i) minus (ii), the “Remaining Trust Amount”),
is less than $100,000,000, in which event the Sponsor Contingent Closing Shares will be cancelled by Parent for no consideration.
For the avoidance of doubt, if the Remaining Trust Amount is equal to or greater than $100,000,000, then the Sponsor Contingent
Closing Shares shall not be subject to forfeiture, cancellation or vesting.

 

     

     

    

 

		3.	Subject to the satisfaction or waiver of each of the conditions to Closing set forth in Sections
8.1 and 8.3 of the Merger Agreement, effective immediately prior to and conditioned upon the consummation of the Closing, Sponsor
and SRAC Partners each hereby waive any and all rights they have or will have under Section 4.3(b)(ii) of Parent’s Amended
and Restated Certificate of Incorporation to receive, with respect to each share of Parent Class B Common Stock held by Sponsor
or SRAC Partners, more than one (1) share of Parent Class A Common Stock upon automatic conversion of such shares of Parent Class
B Common Stock in accordance with Parent’s Amended and Restated Certificate of Incorporation in connection with the consummation
of the Transactions. Without limitation of the foregoing, upon the consummation of the Transactions, Sponsor and SRAC Partners
each hereby acknowledge and agree that pursuant to Section 4.3(b)(i) of Parent’s Amended and Restated Certificate of Incorporation,
each share of Parent Class B Common Stock held by either Sponsor or SRAC Partners shall automatically convert into one (1) share
of Parent Class A Common Stock.

 

		4.	Upon and subject to the Closing, 1,437,500 shares of Parent Class A Common Stock owned by Sponsor
(the “Sponsor Earnout Shares”) shall become subject to potential forfeiture upon the terms set forth in Article
III of the Merger Agreement, such that such Sponsor Earnout Shares shall be forfeited if, and only if, the applicable vesting condition(s)
set forth in Article III of the Merger Agreement are not satisfied prior to the expiration of the Earnout Period. If all or any
portion of the Sponsor Earnout Shares vest in accordance with the terms of the Merger Agreement, any restrictive legends that have
been placed on the Sponsor Earnout Shares, other than those, if any, required by applicable securities laws, shall be removed (and
Parent hereby agrees to promptly cause the removal of such restrictive legends that have been placed on the applicable portion
of the Sponsor Earnout Shares), and such vested Sponsor Earnout Shares shall not thereafter be subject to forfeiture, cancellation
or additional vesting.

 

		5.	During the period commencing on the date hereof and ending on the earlier of the Closing and the
termination of the Merger Agreement pursuant to Article IX thereof, if, and as often as, the outstanding shares of Parent Class
A Common Stock or Parent Class B Common Stock shall have been changed into a different number of shares or a different class, by
reason of any dividend, subdivision, reclassification, recapitalization, split, combination or exchange, or any similar event shall
have occurred, then the number of Sponsor Contingent Closing Shares and Sponsor Earnout Shares to be surrendered or forfeited pursuant
to Section 2 or Section 4 of this Letter Agreement (and, in the case of the Sponsor Earnout Shares, Article III of
the Merger Agreement), will in each case be equitably adjusted to reflect such change.

 

		6.	Holders of the Sponsor Earnout Shares shall be entitled to vote such Sponsor Earnout Shares and
receive dividends and other distributions in respect thereof prior to the vesting of such Sponsor Earnout Shares in accordance
with the terms herein; provided, that any such dividends and other distributions in respect of the Sponsor Earnout Shares
that are subject to vesting pursuant to the terms herein at the time of payment of such dividend or other distribution shall be
set aside by Parent and shall be paid to the holder of such Sponsor Earnout Shares promptly following the vesting thereof (as applicable).

 

    2

     

    

 

		7.	Parent, Sponsor and to the extent applicable, SRAC Partners are subject to the terms and conditions
of that certain letter agreement dated November 7, 2019 in connection with the initial public offering of Parent (the “Prior
Letter Agreement”). The parties hereto acknowledge and agree that the Prior Letter Agreement shall survive the consummation
of the Transactions in accordance with its terms, and Sponsor shall comply with, and fully perform all of its obligations, covenants
and agreements set forth in, the Prior Letter Agreement; provided, that the parties agree that (and the Company, by its
acceptance of this Letter Agreement, acknowledges that) (i) the phrase “one year” in clause (A) of Section 7(a) of
the Prior Letter Agreement is hereby replaced with the phrase “six months”, and (ii) the phrase “at least 150
days” in clause (B)(x) of Section (7)(a) of the Prior Letter Agreement is hereby deleted.

 

		8.	During the period commencing on the date hereof and ending on the earlier of the Closing and the
termination of the Merger Agreement pursuant to Article IX thereof, Sponsor shall not, without the prior written consent of the
Company (which consent shall not be unreasonably withheld, conditioned or delayed), modify or amend any Contract between or among
Sponsor or any Affiliate of Sponsor (other than Parent or any of its Subsidiaries), on the one hand, and Parent or any of Parent’s
Subsidiaries, on the other hand (including, for the avoidance of doubt, the Prior Letter Agreement).

 

		9.	Sponsor and SRAC Partners each hereby acknowledge that they have read the Merger Agreement and
this Letter Agreement and have had the opportunity to consult with their tax and legal advisors with respect thereto. Sponsor and
SRAC Partners shall each be bound by and comply with Section 7.2 (Parent No Solicitation) and the final sentence of Section 7.8(c)
(Confidentiality; Communications Plan; Access to Information) of the Merger Agreement (and any relevant definitions contained in
any such Sections) as if Sponsor and SRAC Partners were original signatories to the Merger Agreement with respect to such provisions,
mutatis mutandis.

 

		10.	During the period commencing on the date hereof and ending on the earlier of the Closing and the
termination of the Merger Agreement pursuant to Article IX thereof, at any meeting of the stockholders of Parent, or at any postponement
or adjournment thereof, called to seek the affirmative vote of the holders of the outstanding Parent Shares entitled to vote thereon
to adopt the Merger Agreement or in any other circumstances upon which a vote, consent or other approval of the stockholders of
Parent with respect to the Merger Agreement, the Mergers or the other transactions contemplated by the Merger Agreement is sought,
Sponsor and SRAC Partners shall each vote (or cause to be voted) all Parent Shares entitled to vote thereon currently or hereinafter
owned by Sponsor and SRAC Partners in favor of the foregoing.

 

    3

     

    

 

		11.	During the period commencing on the date hereof and ending on the earlier of the Closing and the
termination of the Merger Agreement pursuant to Article IX thereof, at any meeting of the stockholders of Parent or at any postponement
or adjournment thereof or in any other circumstances upon which Sponsor’s and SRAC Partners’ vote, consent or other
approval (including by written consent) of the stockholders of Parent is sought, Sponsor and SRAC Partners shall each vote (or
cause to be voted) all Parent Shares entitled to vote thereon, currently or hereinafter owned by Sponsor and SRAC Partners against
and withhold consent with respect to any Parent Acquisition Transaction (other than the Merger Agreement and the transactions contemplated
thereby, including the Mergers). Neither Sponsor nor SRAC Partners shall commit or agree to take any action in contravention of
the foregoing that would be effective prior to the earlier of the Closing and the termination of the Merger Agreement pursuant
to Article IX thereof.

 

		12.	During the period commencing on the date hereof and ending on the earlier of the Closing and the
termination of the Merger Agreement pursuant to Article IX thereof, without the prior written consent of the Company, Sponsor and
SRAC Partners each agree not to (a) transfer any Parent Shares or (b) deposit any Parent Shares into a voting trust or enter into
a voting agreement or any similar agreement, arrangement or understanding with respect to Parent Shares or grant any proxy (except
as otherwise provided herein), consent or power of attorney with respect thereto (other than pursuant to this Letter Agreement)
that conflict with Sponsor’s and SRAC Partners’ obligations pursuant to Section 10 or Section 11;
provided, that Sponsor and SRAC Partners each may, without the Company’s prior written consent, transfer any such
Parent Shares to any Affiliate of Sponsor or SRAC Partners, respectively, if, and only if, the transferee of such Parent Shares
evidences in a writing reasonably satisfactory to Parent such transferee’s agreement to be bound by and subject to the terms
and provisions hereof to the same effect as Sponsor or SRAC Partners, respectively (to the extent applicable to such transferred
Parent Shares).

 

		13.	During the period commencing on the date hereof and ending on the earlier of the Closing and the
termination of the Merger Agreement pursuant to Article IX thereof, Sponsor and SRAC Partners each agree that any Parent Shares
that either Sponsor or SRAC Partners purchases or otherwise hereinafter acquires or with respect to which either otherwise acquires

by Parent of each of the representations, warranties and agreements of Parent contained in this Agreement as of the Closing Date.

 

(c)
At the Closing, the parties hereto shall execute and deliver such additional documents and take such additional actions as the
parties reasonably may deem to be practical and necessary in order to consummate the transactions contemplated by this Agreement,
on the terms and conditions set forth herein.

 

    3

     

    

 

4.
Withholding. Parent, the Company and, following the Second Effective Time, the Surviving Entity, and each of their respective
agents, Affiliates and representatives, shall be entitled to deduct and withhold from any amount payable pursuant to this Agreement
any amounts as may be required to be deducted and withheld from such amounts under the Internal Revenue Code of 1986, as amended,
or any other applicable Law (as reasonably determined by Parent, the Company and, following the Second Effective Time, the Surviving
Entity, respectively). To the extent that any amounts are so deducted and withheld, such deducted and withheld amounts shall be
treated for all purposes of this Agreement as having been paid to the person in respect of which such deduction and withholding
was made. In the event that withholding was required, to the extent that such amounts are not so deducted and withheld from any
Person, such Person shall indemnify Parent, the Company and, following the Second Effective Time, the Surviving Entity, and each
of their respective agents, Affiliates and representatives that was required to perform such withholding, for such amounts, together
with any related losses.

 

5.
The Holder acknowledges and agrees that the Holder Expense Amount shall represent the Holder’s obligation to pay the Company
a portion of the Company Transaction Costs, and Parent, the Holder and the Company each hereby agree that Parent can withhold
the Holder Expense Amount from the Aggregate Repurchase Price in full satisfaction and release of the Holder’s obligation
to pay the Company such portion of the Company Transaction Costs.

 

6.
Parent Representations and Warranties. Parent represents and warrants to the Holder that:

 

(a)
Due Incorporation, Authorization and Enforceability. Parent is duly incorporated and in good standing under the laws of
the State of Delaware. Subject to obtaining the approvals in connection with Parent’s performance of the Merger Agreement,
this Agreement and the transactions contemplated thereby and hereby (the “Required Approvals”), (i) Parent
has all requisite corporate power and authority to execute and deliver this Agreement and to consummate the Repurchase, (ii) this
Agreement has been duly authorized, executed and delivered by Parent, and (iii) assuming due authorization, execution and delivery
by, and enforceability against, the Holder, this Agreement constitutes the valid and binding obligation of Parent, enforceable
against Parent in accordance with its terms, subject to the Remedies Exception.

 

(b)
No Conflict. Subject to obtaining the Required Approvals, the execution and delivery by Parent of this Agreement and the
consummation by Parent of the Repurchase will not (i) conflict with Parent’s certificate of incorporation and bylaws, as
in effect at the time of such execution and delivery and the Repurchase, respectively, (ii) violate or conflict with any provision
of, or result in the breach of, or default under any applicable Law or governmental order applicable to Parent, or (iii) violate
or conflict with any provision of, or result in the breach of, result in the loss of any right or benefit, or cause acceleration,
or constitute (with or without due notice or lapse of time or both) a default (or give rise to any right of termination, cancellation
or acceleration) under any contract, agreement or instrument (“Contract”) to which Parent is a party or by
which Parent may be bound, or terminate or result in the termination of any such Contract, except, in the case of clauses (ii)
and (iii), to the extent that the occurrence of the foregoing would not have, or would not reasonably be expected to have, individually
or in the aggregate, a material adverse effect on the ability of Parent to enter into and perform its obligations under this Agreement.

 

    4

     

    

 

(c)
No Consents. Subject to obtaining the Required Approvals, no consent, waiver, approval or authorization of, or designation,
declaration or filing with, or notification to, any Governmental Entity or other person is required on the part of Parent with
respect to Parent’s execution or delivery of this Agreement or the consummation of the Repurchase.

 

(d)
No Other Representations or Warranties. Parent acknowledges that there have been no representations, warranties, covenants
and agreements made to Parent by the Holder, expressly or by implication, other than those representations, warranties, covenants
and agreements included in this Agreement.

 

7.
Holder Representations and Warranties. The Holder represents and warrants to Parent that:

 

(a)
Authorization and Enforceability. The Holder is duly organized and in good standing as a limited partnership under the
laws of the State of Delaware and is treated as a partnership for applicable income tax purposes. The execution and delivery by
the Holder of this Agreement, the performance by the Holder of its obligations hereunder and the consummation by the Holder of
the transactions contemplated hereby, have been duly authorized by all requisite action on the part of the Holder. This Agreement
has been duly executed and delivered by the Holder, and (assuming due authorization, execution and delivery by, and enforceability
of this Agreement against, Parent) this Agreement constitutes a legal, valid and binding obligation of the Holder, enforceable
against the Holder in accordance with its terms, subject to the Remedies Exception.

 

(b)
No Conflict. The execution and delivery by the Holder of this Agreement, the performance by the Holder of its obligations
hereunder and the consummation by the Holder of the transactions contemplated hereby will not (i) conflict with the Holder’s
partnership agreement, certificate of limited partnership and other organizational documents, as in effect at the time of such
execution and delivery and the Repurchase, respectively, (ii) violate or conflict with any provision of, or result in the breach
of, or default under any applicable Law or governmental order applicable to the Holder, or (iii) violate or conflict with any
provision of, or result in the breach of, result in the loss of any right or benefit, or cause acceleration, or constitute (with
or without due notice or lapse of time or both) a default (or give rise to any right of termination, cancellation or acceleration)
under any Contract to which the Holder is a party or by which the Holder may be bound, or terminate or result in the termination
of any such Contract, except, in the case of clauses (ii) and (iii), to the extent that the occurrence of the foregoing would
not have, or would not reasonably be expected to have, individually or in the aggregate, a material adverse effect on the ability
of the Holder to enter into and perform its obligations under this Agreement.

 

(c)
No Consents. No consent, waiver, approval or authorization of, or designation, declaration or filing with, or notification
to, any Governmental Entity or other person is required on the part of the Holder with respect to the execution and delivery by
the Holder of this Agreement, the performance by the Holder of its obligations hereunder and the consummation by the Holder of
the transactions contemplated hereby.

 

    5

     

    

 

(d)
Ownership of Repurchase Shares. Immediately prior to the Closing, the Holder will own, beneficially and of record, and
will have valid title to, and the right to transfer to Parent, all of the Repurchase Shares to be sold by the Holder to Parent
pursuant to this Agreement, free and clear of any Lien of any kind or nature whatsoever. At the Closing, upon delivery from the
Holder of the Repurchase Shares in book entry form to Parent, in accordance with the terms of this Agreement, or to a custodian
designated by Parent prior to the Closing, and payment of the Repurchase Price for such Repurchase Shares, good and valid title
to such Repurchase Shares, free and clear of all Liens, will pass to Parent. No person has any written or oral agreement, arrangement
or understanding or option for, or any right or privilege (whether by Law, preemption or contract) that is or is capable of becoming
an agreement, arrangement or understanding or option for, the purchase or acquisition from the Holder of any of the Repurchase
Shares.

 

(e)
Information. The Holder acknowledges that it knows that Parent may have material, non-public information regarding Parent
and its condition (financial and otherwise), results of operations, businesses, properties, plans and prospects (collectively,
“Information”). The Holder acknowledges that it has been offered and does not wish to receive any of this Information
and that such Information might be material to the Holder’s decision to sell the Repurchase Shares or otherwise materially
adverse to the Holder’s interests. Accordingly, the Holder acknowledges and agrees that Parent shall not have any obligation
to disclose to the Holder any of such Information. The Holder, either alone or together with its representatives, has such knowledge,
sophistication and experience in business and financial matters so as to be capable of evaluating the transactions contemplated
by this Agreement, including the Repurchase. The Holder hereby waives and releases, to the fullest extent permitted by applicable
Law, any and all claims and causes of action it has or may have against Parent and its Affiliates, controlling persons, officers,
directors, employees, representatives and agents, based upon, relating to or arising out of the Repurchase and the other transactions
contemplated hereby, including (without limitation) any claim or cause of action based upon, relating to or arising out of nondisclosure
of the Information.

 

(f)
No Other Representations or Warranties. The Holder acknowledges that there have been no representations, warranties, covenants
and agreements made to the Holder by Parent, or its officers or directors, expressly or by implication, other than those representations,
warranties, covenants and agreements included in this Agreement.

(b)
Headings; Counterparts. The headings 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 or more counterparts,
each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

 

(c)
Expenses. Except as otherwise expressly provided herein, all costs and expenses, including, without limitation, fees and
disbursements of counsel, financial advisors and accountants, incurred in connection with this Agreement and the transactions
contemplated hereby shall be paid by the party incurring such costs and expenses, whether or not the Closing shall have occurred.

 

(d)
Entire Agreement; Third-Party Beneficiaries. This Agreement constitutes the entire agreement among the parties relating
to the transactions contemplated hereby and supersedes any other agreements, whether written or oral, that may have been made
or entered into by or among any of the parties hereto relating to the transactions contemplated hereby. Nothing expressed or implied
in this Agreement is intended or shall be construed to confer upon or give any Person, other than the parties hereto, any right
or remedies under or by reason of this Agreement.

 

(e)
Severability. If any provision of this Agreement is held invalid or unenforceable by any court of competent jurisdiction,
the other provisions of this Agreement shall remain in full force and effect. The parties further agree that if any provision
contained herein is, to any extent, held invalid or unenforceable in any respect under the laws governing this Agreement, they
shall take any actions necessary to render the remaining provisions of this Agreement valid and enforceable to the fullest extent
permitted by Law and, to the extent necessary, shall amend or otherwise modify this Agreement to replace any provision contained
herein that is held invalid or unenforceable with a valid and enforceable provision giving effect to the intent of the parties.

 

(f)
Governing Law; Jurisdiction. 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. Any proceeding or action based upon, arising out of or
related to this Agreement or the transactions contemplated hereby must be brought in the Court of Chancery of the State of Delaware
(or, to the extent such Court does not have subject matter jurisdiction, the Superior Court of the State of Delaware), or, if
it has or can acquire jurisdiction, in the United States District Court for the District of Delaware, and each of the parties
irrevocably submits to the exclusive jurisdiction of each such court in any such proceeding or 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
proceeding or action shall be heard and determined only in any such court, and agrees not to bring any proceeding or 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,
suit or proceeding brought pursuant to this Section 8(f).

 

    8

     

    

 

(g)
Waiver of Jury Trial. Each party acknowledges and agrees that any controversy
which may arise under this Agreement and the transactions contemplated hereby is likely to involve complicated and difficult issues,
and therefore each such party hereby irrevocably, unconditionally and voluntarily waives any right such party may have to a trial
by jury in respect of any action, suit or proceeding directly or indirectly arising out of or relating to this Agreement or any
of the transactions contemplated hereby.

 

(h)
Assignment. No party hereto shall assign this Agreement or any part hereof without the prior written consent of the other
parties and any such transfer without prior written consent shall be void. 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.

 

(i)
Publicity.

 

(i)
All press releases or other public communications relating to the transactions contemplated hereby, and the method of the release
for publication thereof, shall be subject to the prior mutual approval of Parent and the Holder, which approval shall not be unreasonably
withheld, conditioned or delayed; provided, however that no consent shall be required for any communications to a director, manager,
officer, stockholder, partner, limited partner, member, potential investor or affiliate of such entity or an investment fund or
other entity controlled or managed by such entity or any of its affiliates.

 

(ii)
The restriction in Section 8(i)(i) shall not apply to the extent the public announcement is required by applicable securities
law, any Governmental Entity or stock exchange rule; provided, however, that in such an event, the party making
the announcement shall use its commercially reasonable efforts to consult with the other parties in advance as to its form, content
and timing.

 

(j)
Amendment and Modification; Waiver. This Agreement may be amended or modified in whole or in part, only by a duly authorized
agreement in writing executed in the same manner as this Agreement and which makes reference to this Agreement. No waiver by any
party of any of the provisions hereof shall be effective unless explicitly set forth in writing and signed by the party so waiving.
No waiver by any party shall operate or be construed as a waiver in respect of any failure, breach or default not expressly identified
by such written waiver, whether of a similar or different character, and whether occurring before or after that waiver. No failure
to exercise, or delay in exercising, any right, remedy, power or privilege arising from this Agreement shall operate or be construed
as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder preclude any
other or further exercise thereof or the exercise of any other right, remedy, power or privilege.

 

    9

     

    

 

(k)
Enforcement. The parties hereto agree that irreparable damage could occur in the event that any of the provisions of this
Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that
the parties shall be entitled to seek an injunction or injunctions to prevent breaches of this Agreement and to seek specific
enforcement of the terms and provisions of this Agreement, in addition to any other remedy to which any party is entitled at law
or in equity. In the event that any action shall be brought in equity to enforce the provisions of this Agreement, no party shall
allege, and each party hereby waives the defense, that there is an adequate remedy at law, and each party agrees to waive any
requirement for the securing or posting of any bond in connection therewith.

 

(l)
Non-Recourse. This Agreement may only be enforced against, and any claim or cause of action based upon, arising out of,
or related to this Agreement or the transactions contemplated hereby may only be brought against, the entities that are expressly
named as parties hereto and any express guarantor of any such party’s obligations hereunder and then only with respect to
the specific obligations set forth herein with respect to such party; provided, however, that the foregoing shall
not relieve any party for liability with respect to fraud.

 

(m)
Termination. This Agreement shall terminate and be void and of no further force and effect and all rights and obligations
of the parties hereunder shall terminate without any further liability on the part of any party in respect thereof, upon the earliest
to occur of (i) such date and time as the Merger Agreement is terminated in accordance with its terms, (ii) upon the mutual written
agreement of each of the parties hereto to terminate this Agreement, or (iii) if any of the conditions to Closing set forth in
Section 3(b) of this Agreement are not satisfied or waived, or are not capable of being satisfied, on or prior to the Closing
and, as a result thereof, the transactions contemplated by this Agreement will not be and are not consummated at the Closing;
provided, that nothing herein shall relieve any party from liability for any willful breach hereof prior to the time of
termination.
