Section 1. Board Composition and Related Agreements.


 


(a) Board Appointment.


 


(i)                
On or prior to the date hereof, the Board of Directors of the Company (the “Board”) and all applicable committees
thereof shall take all necessary actions to, effective on the date hereof (A) increase the size of the Board to nine (9) members and (B)
appoint David Johnson (“Mr. Johnson”) as a Class II director for a term expiring at the Company’s 2023 annual
meeting of stockholders (the “2023 Annual Meeting”), and until his successor is duly elected and qualified, or until
such director’s earlier resignation, removal or death; provided, however, that, notwithstanding the foregoing, in
the event that (x) each of the conditions precedent to consummating the transactions contemplated by the Purchase Agreement have not been
satisfied, (i) Mr. Johnson shall immediately resign as a director of the Company as well as a member of any committees of the Company
which Mr. Johnson is then serving, (ii) the New Company Investor shall not have any rights to appoint a Replacement Designee pursuant
to Section 1(a)(iv) hereto, and (iii) the Company shall not be obligated to nominate Mr. Johnson as a Class II director for the
election of directors at the 2023 Annual Meeting pursuant to Section 1(b).


 


(ii)             
The Parties acknowledge that, at all times while serving as a member of the Board (and as a condition to such service), Mr. Johnson
shall be subject to all policies, codes, guidelines and reasonable requests applicable to Board members generally, each as may be amended
from time to time, including the Company’s Code of Conduct, and shall have the same rights and benefits, including with respect
to insurance, indemnification, compensation, fees and reimbursement of expenses, as are applicable to all non-employee directors
of the Company.


 






     


     


    

 


(iii)           
Subject to any applicable corporate governance documents of the Company and applicable stock exchange rules, concurrently with
the Mr. Johnson’s appointment to the Board, Mr. Johnson shall also be appointed to the Audit Committee of the Board, subject to
Section 1(a)(i), the Company agrees to maintain such committee appointment during the term of this Agreement, as long as Mr. Johnson
(or, as applicable, his Replacement Designee (as defined below)) continues to serve on the Board.


 


(iv)            
Subject to Section 1(a)(i), during the Standstill Period (defined below), as long as the New Company Investor owns at least
66% of the Company’s Voting Securities (as defined below) owned by the New Company Investor as of the Closing Date (as defined in
the Purchase Agreement) (and subject to adjustment for stock splits, reclassifications, combinations, buybacks or similar transactions,
the “Ownership Minimum”) and in the event that Mr. Johnson (or any Replacement Designee (as defined below), as applicable)
becomes unwilling or unable to serve as a director and ceases to be a director, resigns as a director or is removed as a director, or
for any other reason fails to serve or is not serving as a director at any time prior to the end of the Cooperation Period, then the members
of the New Company Investor shall be entitled to designate, subject to the approval (not to be unreasonably withheld) of the applicable
committee of the Board, a candidate for replacement of such New Director (such replacement, a “Replacement Designee”).
Any Replacement Designee shall qualify as an independent director of the Company under applicable rules of the SEC, the rules of any stock
exchange on which the Company is traded and applicable governance policies of the Company. Following the approval of a candidate for Replacement
Designee by the applicable committee of the Board, the Board shall promptly appoint such Replacement Designee to the Board. Upon his or
her appointment to the Board, such Replacement Designee shall be deemed a New Director for all purposes under this Agreement.


 


(v)              
New Director Nominations. Subject to Section 1(a)(i), provided that the New Company Investor owns the Ownership Minimum,
the Company’s slate of Class II director nominees for the election of directors at the 2023 Annual Meeting shall include Mr. Johnson
as a nominee. Subject to Section 1(a)(i), provided that the New Investor owns the Ownership Minimum, the Company will recommend that the
Company’s stockholders vote in favor of the election of Mr. Johnson at the 2023 Annual Meeting and will support Mr. Johnson for
election in a manner consistent with its support for the other nominees of the Company. Subject to Section 1(a)(i), provided that the
New Company Investor owns the Ownership Minimum, the Company will cause all Voting Securities represented by proxies granted to it (or
any of its Representatives) to be voted in favor of the election of Mr. Johnson as a director at the 2023 Annual Meeting, to the extent
permitted pursuant to such proxies.


 


(b) Additional Agreements.


 


(i)                
The New Company Investor agrees (A) to cause its Affiliates and Representatives (each as defined below) to comply with the terms
of this Agreement and (B) that it shall be responsible for any breach of this Agreement by any such Affiliate or Representative. A breach
of this Agreement by an Affiliate or Representative of the New Company Investor, if such Affiliate or Representative is not a Party hereto,
shall be deemed to occur if such Affiliate or Representative engages in conduct that would constitute a breach of this Agreement if such
Affiliate or Representative were a Party hereto to the same extent as the New Company Investor.


 






    2


     


    

 


(ii)

in person or by proxy at each annual or special meeting of the stockholders of the Company (each, a “Stockholder Meeting”)
and vote all Voting Securities beneficially owned, directly or indirectly, by the New Company Investor or such Affiliate (or which the
New Company Investor or such Affiliate has the right or ability to vote as of the applicable record date) at such meeting (A) in favor
of the slate of directors recommended by the Board, (B) against the election of any nominee for director not approved, recommended and
nominated by the Board for election at any such Stockholder Meeting and (C) in accordance with the Board’s recommendation with respect
to any other matter presented at such Stockholder Meeting; provided, that the New Company Investor shall be permitted to vote
in its sole discretion with respect to any proposals relating to (i) an Extraordinary Transaction (as defined below) with a third party
that is not an Affiliate of the New Company Investor, or (ii) amendments to the Company’s Certificate of Incorporation, Bylaws,
or other governing documents of the Company that materially diminish stockholder rights.


 


(iii)           
During the Standstill Period, upon reasonable written request from the Company, the New Company Investor will promptly provide
the Company with information regarding the amount of the Voting Securities then beneficially owned by the New Company Investor. Such information
provided to the Company will be kept strictly confidential unless required to be disclosed pursuant to law, legal process, subpoena, the
rules of any stock exchange or any legal requirement or as part of a response to a request for information from any governmental authority
with jurisdiction over the Company.


 


(iv)            
Each Party (as defined below) agrees that, during the Standstill Period, it shall not institute, solicit, join or assist in any

of one Party or its Affiliates against the other Party or its Affiliates, (C) to bring bona fide commercial disputes that do not relate

subpoenas, civil investigative demands or similar processes (each, a “Legal Requirement”) in connection with any Legal
Proceeding if such Legal Proceeding has not been initiated by, on behalf of or at the suggestion of such Party; provided, further,
that in the event that any Party or any of its Representatives receives such Legal Requirement, such Party shall give prompt written notice
of such Legal Requirement to the other Party (except where such notice would be legally prohibited or not practicable). Each Party represents
and warrants that neither it nor any assignee has filed any lawsuit against the other Party.

Section 14. Non-Disparagement.


 


(a) Subject to applicable law,
each of the Parties covenants and agrees that during the period commencing upon the execution of this Agreement and ending on the earlier
of (i) the conclusion of the Standstill Period and (ii) such time as the other Party or any of its Affiliates, Representatives, successors
or assigns shall have breached this Section 14(a), neither it nor any of its respective Affiliates or any Representatives
acting on their behalf, or its successors or assigns, shall in any way disparage, slander, attempt to discredit, call into disrepute,
defame, make or cause to be made any statement or announcement that constitutes an ad hominem attack on the other Party
or such other Party’s subsidiaries, Affiliates, successors, assigns, officers (including any current or former officer of a Party
or a Party’s subsidiaries), directors (including any current or former director of a Party or a Party’s subsidiaries) or Representatives.

legal process, subpoena, the rules of any stock exchange or any legal requirement or as part of a response to a request for information
from any governmental authority with jurisdiction over the Party from whom information is sought.

The obligations of the Parties under this Agreement will terminate on the date that is the end date of the Standstill Period, unless another
period is specifically set forth herein or otherwise mutually agreed in writing by each Party. The obligations of the New Company Investor
pursuant to Sections 1 and 2 shall terminate in the event that the Company materially breaches its obligations to the New
Company Investor pursuant to Section 1 or the representations and warranties in Section 3 of this Agreement (as they pertain
to the Company) and such breach (if capable of being cured) has not been cured within thirty (30) calendar days following written notice
of such breach from the New Company Investor, or, if impossible to cure within 30 calendar days, the Company has not taken substantive
action to correct within thirty (30) calendar days following written notice of such breach from the New Company Investor. Notwithstanding
the foregoing, (a) Section 7 through Section 13, this Section 15, and Section 16 through Section 20 of
this Agreement will survive the termination of this Agreement; and (b) no termination of this Agreement will relieve any Party of liability
for any breach of this Agreement arising prior to such termination.

Section 16. No Waiver.
Any waiver by any Party of a breach of any provision of this Agreement shall not operate as or be construed to be a waiver of any other
breach of such provision or of any breach of any other provision of this Agreement. The failure of a Party to insist upon strict adherence
to any term of this Agreement on one or more occasions shall not be considered a waiver of, or deprive that Party of the right thereafter
to insist upon strict adherence to, that term or any other term of this Agreement.


 


Section 17. Entire Agreement;
Amendments. This Agreement contains the entire understanding of the Parties with respect to the subject matter hereof. This Agreement
may only be amended pursuant to a written agreement executed by the Company and the New Company Investor.


 


Section 18. Successors
and Assigns. This Agreement may not be transferred or assigned by any Party without the prior written consent of the other Party.
Any purported assignment without such consent is null and void. Subject to the foregoing, this Agreement shall be binding upon, inure
to the benefit of, and be enforceable by and against the permitted successors and assigns of each Party.


 


Section 19. No Third Party
Beneficiaries. This Agreement is solely for the benefit of the Parties and is not enforceable by any other person.

that have preceded the execution of this Agreement, and that it has executed the same with the advice of said independent counsel. Each
Party and its counsel cooperated and participated in the drafting and preparation of this Agreement and the documents referred to herein,
and any and all drafts relating thereto exchanged among the parties shall be deemed the work product of all of the Parties and may not
be construed against any Party by reason of its drafting or preparation. Accordingly, any rule of law or any legal decision that would
require interpretation of any ambiguities in this Agreement against any Party that drafted or prepared it is of no application and is
hereby expressly waived by each Party, and any controversy over any interpretation of this Agreement shall be decided without regard to
events of drafting or preparation. The section headings contained in this Agreement are for reference purposes only and shall not affect
in any way the meaning or interpretation of this Agreement. In this Agreement, (i) the word “including” (in its various forms)
means “including, without limitation,” (ii) the words “hereunder,” “hereof,” “hereto”
