1. Shares. During the term of this Agreement, the Voting Parties each agree to vote all shares of the Company’s voting securities now or hereafter owned by them, whether beneficially or otherwise, or as to which they have voting power (the “Shares”) in accordance with the provisions of this Agreement.

2. Election of Boards of Directors

(a) Voting. During the term of this Agreement, each Voting Party agrees to vote all Shares in such manner as may be necessary to elect (and maintain in office) as members of the Company’s Board of Directors the following individuals:

(ii) notify the Company in writing of an intention to select a new Designee for election to a Board seat for which such Voting Parties are entitled to designate the Designee (whether to replace a prior Designee or to fill a vacancy in such Board seat);
