WHEREAS, the parties hereto desire to enter into this Agreement to set forth certain rights and obligations of the Stockholder with
respect to the Company. 
 NOW, THEREFORE, the parties to this Agreement agree as follows: 

1. Voting Agreement; Board Nomination Rights. 
 (a) From and after the date hereof and until the provisions of this Section 1 cease to be effective and subject to the terms and conditions of this Agreement, the Stockholder (or its indirect
beneficial owners) shall have the right to nominate persons for election to the Board (each a “Nominee”) as follows: 
 (i) (x) prior to the earlier of (A) one year after the Stockholder’s Ownership Percentage becomes less than 50% or (B) the Stockholder’s Ownership Percentage becomes less than 35%,
such number of individuals as are collectively designated by the Stockholder, so long as the Company is able to comply with the requirement of Section 303A.01 of the New York Stock Exchange Listed Company Manual (the “Majority
Independent Director Requirement”) or the Majority Independent Director Requirement does not apply to the Company or (y) after the earlier of (A) or (B) in clause (x) hereof, but while the Stockholder’s Ownership Percentage is at
least 10%, such number of individuals in relative proportion to the Stockholder’s Ownership Percentage (rounded up), so long as the Company is able to comply with the Majority Independent Director Requirement or the Majority Independent
Director Requirement does not apply to the Company; and 
 (ii) subject to the provisions of this Section 1, during
such time as the Stockholder’s Ownership Percentage is at least 35%, the size (i.e., number of Board seats) shall not be more than [            
(        )]. 







 (b) The Company shall pay the reasonable out-of-pocket expenses incurred by each director in
connection with attending the meetings of the Board and any committee thereof. 
 (c) Notwithstanding anything to the contrary
contained herein, at such time as the Stockholder’s Ownership Percentage is less than 10%, the rights of the Stockholder under this Section 1 to nominate any Nominee shall terminate automatically and cease to have any further force
or effect. 
 (d) At every meeting of the Board, or a committee thereof, for which directors are nominated to stand for election
by stockholders of the Company, each Stockholder will have the right to select those persons to be nominated for election to the Board for each Retiring Director that was a prior Nominee of such Stockholder in accordance with this
Section 1. 
 (e) If a vacancy occurs because of the death, disability, disqualification, resignation or removal of
a Nominee (including by virtue of a removal of a Nominee at the discretion of the Stockholder), the Stockholder shall be entitled to nominate such person’s successors in accordance with this Agreement and the Board, subject to a determination
of the Board in good faith, after consultation with outside legal counsel that such action would not constitute a breach of applicable law, shall fill the vacancy with such successor Nominee. 

(f) If a Nominee is not nominated or elected to the Board because of the Nominee’s death, disability, disqualification, withdrawal
as a nominee or for other reason is unavailable or unable to serve on the Board, the Stockholder who nominated such person shall be entitled to nominate promptly another Nominee and the director position for which such Nominee was nominated shall
not be filled pending such nomination. 
 2. Company Obligations. 

(a) The Company agrees to use its commercially reasonable efforts to assure that (i) each Nominee is included in the Board’s
slate of nominees to the stockholders for each election of directors, and (ii) each Nominee is included in the proxy statement prepared by management of the Company in connection with soliciting proxies for every meeting of the stockholders of
the Company called with respect to the election of members of the Board, and at every adjournment or postponement thereof, and on every action or approval by written consent of the stockholders of the Company or the Board with respect to the
election of members of the Board. 
 (b) Notwithstanding anything herein to the contrary, the Company shall not be obligated to
cause to be nominated for election to the Board or recommend to the stockholders the election of any Nominee (i) who fails to submit to the Company on a timely basis such questionnaires as the Company may reasonably require of its directors
generally and such other information as the Company may reasonably request in connection with the preparation of its filings under the Securities Laws, or (ii) the Board or the Nominating Committee determines in good faith, after consultation
with outside legal counsel, that such action would constitute a breach of applicable law; provided, however, that upon the occurrence of either (i) or (ii) above, the Company shall promptly notify the applicable Stockholder
of the occurrence of such event and permit the applicable Stockholder to provide an alternate Nominee sufficiently in advance of 

  
 2 








 
any Board action, meeting of the stockholders called or written action of stockholders with respect to such election of Nominees and the Company shall use commercially reasonable efforts to
perform its obligations under Section 2(a) with respect to such alternate Nominee (provided that if the Company provides at least 45 days advance notice of the occurrence of any such event such alternative Nominee must be
designated by the applicable Stockholder not less than 30 days in advance of any Board action, notice of meeting of the stockholders or written action of stockholders with respect to such election of Nominees). The Company shall use commercially
reasonable efforts to perform its obligations under Section 2(a) with respect to such alternate Nominee, provided that in no event shall the Company be obligated to postpone, reschedule or delay any scheduled meeting of the
stockholders with respect to such election of Nominees. 
 (c) At any time a vacancy occurs because of the death, disability,
resignation or removal of a Nominee, then the Board, or any committee thereof, shall not fill such vacancy until the earliest to occur of (i) such Stockholder has nominated a successor Nominee and the Board has filled the vacancy and appointed
such successor Nominee, (ii) such Stockholder fails to nominate a successor Nominee within 30 Business Days after receiving notification of the vacancy from the Company, and (iii) such Stockholder has specifically waived its right under
this Section 2(c). 
 (d) At any time that any Stockholder shall have any nomination rights under
Section 1, the Company shall not take any action, including making or recommending any amendment to the Certificate of Incorporation or the Company’s bylaws, (i) to reduce the size of the Board from
             (        ) if such decrease would cause the Company to fail to satisfy the Majority Independent Director Requirement without the
