On January 14, 2015, a purported class action lawsuit, captioned Arnold and Georgette Spindler v. William M. Mooney, Jr., et al. was filed in the Court of Chancery of the State of Delaware against CMS Bancorp, Inc. (the “Company”), CMS Bank, the Company’s directors, as well as Putnam County Savings Bank and Putnam County Acquisition Corporation (collectively “Putnam”). The lawsuit alleges that the director defendants breached their fiduciary duties to the Company’s stockholders in connection with their approval and recommendation of the agreement and plan of merger entered into by the Company and CMS Bank with Putnam on September 25, 2014 (the “Proposed Transaction”) and the process leading to same, and in connection with the disclosures to stockholders regarding the Proposed Transaction. The Putnam entities are alleged to have aided and abetted such breaches. The Complaint seeks a declaration that the Proposed Transaction is unfair, unjust and inequitable to Plaintiff and other members of the stockholder Class; a preliminary and permanent injunction enjoining defendants from taking any steps necessary to accomplish or implement the Proposed Transaction; a rescission or setting aside of the Proposed Transaction if consummated, together with rescissory damages to Plaintiff and the Class; a direction that Defendants account for all damages allegedly caused by them and account for all profits and special benefits obtained as a result of the alleged breaches of fiduciary duty; and an award of costs and reasonable allowance for fees and expenses of Plaintiff’s attorneys, accountants and experts. On January 16, 2015, plaintiffs moved the Court for expedited proceedings and to set a hearing on their motion for preliminary injunction.
