(h)		Legal Proceedings

     On January 14, 2011, as amended on January 28, 2011, a putative shareholder class action lawsuit was filed by a single plaintiff, Joseph P. Daly, against the Company, members of the Company’s Board of Directors, IDEX and Purchaser in the Court of Chancery of the State of Delaware. The action alleges, among other things, that the members of the Company’s Board of Directors violated their fiduciary duties by failing to maximize shareholder value when negotiating and entering into the Merger Agreement and that the Schedule 14D-9 Solicitation/Recommendation Statement filed by the Company on January 25, 2011 contained inadequate disclosure in certain respects. The complaint alleges that IDEX and Purchaser aided and abetted those purported violations of fiduciary duties. The plaintiff seeks, among other things, to enjoin the acquisition of the Company by Purchaser and IDEX or, in the alternative, to rescind the acquisition should it occur before the lawsuit is resolved.

     On January 20, 2011, as amended on February 1, 2011, a putative shareholder class action lawsuit was filed by a single plaintiff, Paul Shumsky, against the Company, members of the Company’s Board of Directors, IDEX and Purchaser in the Massachusetts Superior Court (Middlesex County). The action alleges, among other things, that the members of the Company’s Board of Directors violated their fiduciary duties by failing to maximize shareholder value when negotiating and entering into the Merger Agreement and that the Schedule 14D-9 Solicitation/Recommendation Statement filed by the Company on January 25, 2011 contained inadequate disclosure in certain respects. The complaint alleges that IDEX and Purchaser aided and abetted those purported violations of fiduciary duties. The plaintiff seeks, among other things, to enjoin the acquisition of the Company by Purchaser and IDEX. On February 3, 2011, the Massachusetts Superior Court (Middlesex County) granted the defendant’s motion to stay the proceedings in this matter pending resolution of the Delaware litigation described above.

     The Company believes that the allegations in the complaints are without merit and intends to vigorously defend these actions. The foregoing summary of the complaints does not purport to be complete and is qualified in its entirety by reference to the complaints, which have been filed with the SEC as exhibits to the Schedule 14D-9, and which are incorporated herein by reference.
