action as is reasonable and necessary, including the voting of shares of capital stock of the Company by the Voting Parties as

executed a written agreement pursuant to which such person becomes a party to this Agreement and agrees to be bound by all the
provisions hereof as if such person was a Voting Party hereunder.



4.Covenants.
The Company and each Voting Party agrees to take all actions required to ensure that the rights given to each Voting Party hereunder
are effective and that each Voting Party enjoys the benefits thereof. Such actions include, without limitation, the use of best
efforts to cause the nomination of the designees, as provided herein, for election as directors of the Company. Neither the Company
nor any Voting Party will, by any voluntary action, avoid or seek to avoid the observance or performance of any of the terms to
be performed hereunder by the Company or any such Voting Party, as applicable, but will at all times in good faith assist in the
carrying out of all of the provisions of this Agreement and in the taking of all such actions as may be necessary or appropriate
in order to protect the rights of each Voting Party hereunder against impairment.

of Proxy. Should the provisions of this Agreement be construed to constitute the granting of proxies, such proxies shall be
deemed coupled with an interest and are irrevocable for the term of this Agreement.

the Company with a legend reading as follows:



“THE
SHARES EVIDENCED HEREBY ARE SUBJECT TO A VOTING AGREEMENT (A COPY OF WHICH MAY BE OBTAINED FROM THE ISSUER) AND BY ACCEPTING ANY
INTEREST IN SUCH SHARES THE PERSON HOLDING SUCH INTEREST SHALL BE DEEMED TO AGREE TO AND SHALL BECOME BOUND BY ALL THE PROVISIONS
OF SAID VOTING AGREEMENT.”

shall be the proper subject of a temporary or permanent injunction or restraining order. Further, each party hereto waives any
claim or defense that there is an adequate remedy at law for such breach or threatened breach and agrees that a party’s rights
would be materially and adversely affected if the obligations of the other parties under this Agreement were not carried out in
accordance with the terms and conditions hereof.

or prospectively) only with the written consent of (a) the Company, and (b) the holders of a majority of Voting Shares then held
