WHEREAS, the
Company, SHLL Merger Sub Inc., a Delaware corporation and wholly owned subsidiary of the Company (“Merger Sub”),

approval and adoption of the BCA and the Merger and approval and adoption of the Second Amended and Restated Certificate of Incorporation
of the Company (the “Charter Proposals”), which provides for, among other things, a reclassification
of the Board of Directors of the Company (the “Board”); and


 


WHEREAS, in
connection with the BCA, the Stockholders and the Company have entered into this Agreement to set forth certain understandings
among such parties, including with respect to certain governance and voting matters.


 


NOW, THEREFORE,

to the Board at the Company’s annual meeting of stockholders in 2021 (the “First Annual Meeting”)
each of Vincent T. Cubbage and Thomas Healy, each to serve until the Company’s annual meeting of stockholders in 2024, or
until their successors are elected and qualified, and to solicit proxies or consents in favor thereof.


 


Section 1.2

or agree to be bound by any voting trust, agreement or arrangement of any kind with respect to their shares of Class A Common
Stock if and to the extent the terms thereof conflict with the provisions of this Agreement (whether or not such proxy, voting
trust, agreement or agreements are with other holders of shares of Class A Common Stock that are not parties to this Agreement
or otherwise).

Section 3.6
Governing Law; Equitable Remedies. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS
OF THE STATE OF DELAWARE (WITHOUT GIVING EFFECT TO CONFLICT OF LAWS PRINCIPLES THEREOF). The parties hereto agree that irreparable
damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with its specific
terms or was otherwise breached. It is accordingly agreed that the parties hereto shall be entitled to an injunction or injunctions
and other equitable remedies to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof

arising out of or relating to this Agreement, each of the parties hereto hereby irrevocably (a) submits to the exclusive
jurisdiction of the Court of Chancery of the State of Delaware and the United States District Court for the District of Delaware
and the appellate courts therefrom (the “Selected Courts”) and waives any objection to venue being laid
in the Selected Courts whether based on the grounds of forum non conveniens or otherwise and hereby agrees not to commence any
such Proceeding other than before one of the Selected Courts; provided, however, that a party may commence any Proceeding
in a court other than a Selected Court solely for the purpose of enforcing an order or judgment issued by one of the Selected
Courts; (b) consents to service of process in any Proceeding by the mailing of copies thereof by registered or certified
mail, postage prepaid, or by recognized international express carrier or delivery service, to their respective addresses referred
to in Section 3.1 hereof; provided, however, that nothing herein shall affect the right of any party
hereto to serve process in any other manner permitted by law; and (c) TO THE EXTENT NOT PROHIBITED BY APPLICABLE LAW THAT
CANNOT BE WAIVED, WAIVES, AND COVENANTS THAT IT WILL NOT ASSERT (WHETHER AS PLAINTIFF, DEFENDANT OR OTHERWISE) ANY RIGHT TO TRIAL
BY JURY IN ANY ACTION ARISING IN WHOLE OR IN PART UNDER OR IN CONNECTION WITH THIS AGREEMENT, WHETHER NOW EXISTING OR HEREAFTER
ARISING, AND WHETHER SOUNDING IN CONTRACT, TORT OR OTHERWISE, AND AGREES THAT ANY OF THEM MAY FILE A COPY OF THIS PARAGRAPH WITH
ANY COURT AS WRITTEN EVIDENCE OF THE KNOWING, VOLUNTARY AND BARGAINED-FOR AGREEMENT AMONG THE PARTIES IRREVOCABLY TO WAIVE THE
RIGHT TO TRIAL BY JURY IN ANY PROCEEDING WHATSOEVER BETWEEN THEM RELATING TO THIS AGREEMENT AND TO HAVE ALL MATTERS RELATING TO
THIS AGREEMENT BE TRIED IN A COURT OF COMPETENT JURISDICTION BY A JUDGE SITTING WITHOUT A JURY.


 


Section 3.8
Amendments; Waivers.


 


(a) No provision of
this Agreement may be amended or waived unless such amendment or waiver is in writing and signed (i) in the case of an amendment,
by each of the parties hereto, and (ii) in the case of a waiver, by each of the parties against whom the waiver is to be effective.


 


(b) No failure or delay
by any party in exercising any right, power or privilege hereunder shall operate as waiver thereof nor shall any single or partial
exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights
and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by law.


 


Section 3.9
Assignment. Neither this Agreement nor any of the rights or obligations
hereunder shall be assigned or delegated by any of the parties hereto without the prior written consent of the other parties.
Subject to the preceding sentence, this Agreement will be binding upon, inure to the benefit of and be enforceable by the parties

director, officer, employee, incorporator, member, manager, partner, stockholder, agent, attorney or representative of any party
