Each of the undersigned, as a holder of voting securities of the Company, shall be present in person or by proxy at all meetings of stockholders of the Company so that all voting securities held by him/it are counted for purposes of determining the presence of a quorum at such meeting.

2. Each of the parties hereto represents that he/it has full power to enter into this Agreement and has not, prior to the date of this Agreement, executed or delivered any proxy or entered into any other voting agreement or similar arrangement with respect to the securities of the Company, other than one that has expired or terminated prior to the date hereof.
