WHEREAS, the Stockholder is the record and beneficial owner (within the meaning of Rule 13d-3 under the Exchange Act, which meaning will apply for all purposes of this Agreement whenever the term “beneficial owner” or “beneficially own” is used) of shares of capital stock of the Company (“Shares”) as set forth on Schedule A hereto (the “Owned Shares”; the Owned Shares and any additional Shares or other voting securities of the Company of which the Stockholder acquires record or beneficial ownership after the date hereof, including, without limitation, by purchase, gift, as a result of a stock dividend, stock split, recapitalization, combination, reclassification, exchange, transfer or change of such shares, or upon exercise or conversion of any securities, the Stockholder’s “Covered Shares”);

(d) There is no action, suit, investigation, complaint or other proceeding pending or, to the knowledge of the Stockholder, threatened against or affecting the Stockholder or any of its Affiliates
