THIS AMENDMENT NO. 2 TO SCHEDULE 13D is filed jointly by the individual persons listed in Item 2 below. In this Schedule 13D, the individual persons listed in Item 2 below are sometimes individually referred to as a “Reporting Person” and collectively as the “Reporting Persons.” The Reporting Persons are making this single, joint filing because they may be deemed to constitute a “group” within the meaning of Section 13(d)(3) of the Securities Exchange Act of 1934, as amended (the “Act”), with respect to the transaction described in Item 4 of this Schedule 13D and thus are eligible to make a joint filing under Rule 13d-1(k) promulgated under the Act. Except as expressly set forth in this Schedule 13D, each Reporting Person disclaims beneficial ownership of the Common Shares beneficially owned by the other Reporting Persons or any other person. The agreement between the Reporting Persons relating to the joint filing of this Amendment to Schedule 13D is attached hereto as Exhibit 1. This joint filing shall also serve to amend the Schedule 13G most recently filed with the Securities and Exchange Commission (the “SEC”) by each of the following Reporting Persons: Barbara P. Ruhlman, Robert G. Ruhlman and John D. Drinko.
