~~Item~~ On April 128, 2004, Gundle/SLT Environmental, Inc. ~~Results~~(the “Company”) announced that it, its directors, and a prospective buyer of ~~Operations~~the Company had executed a Memorandum of Understanding (“MOU”) reflecting an agreement in principle with the plaintiffs to settle three putative class action lawsuits filed in January 2004 in the Delaware Court of Chancery (Calhoun v. Gundle/SLT Environmental, Inc., et al., C.A. No. 153-N, Twist Partners LLP v. Badawi, et al., C.A. No. 150-N, and ~~Financial~~Bell ~~Condition~~v. Gundle/SLT Environmental, Inc., et al., C.A. No. 169-N). The complaints alleged that the Company’s board breached its fiduciary duty by authorizing the merger of the Company with an indirect wholly owned subsidiary of Code Hennessy & Simmons IV LP. The agreement in principle to settle these actions is based upon enhanced disclosures regarding the merger, all of which are included in our proxy statement filed with the U.S. Securities and Exchange Commission. The Company expects to commence the mailing of this proxy statement to our stockholders next week. The MOU also includes the defendants’ agreement to pay the plaintiffs’ attorneys’ fees, costs and expenses up to $330,000, subject to approval by the Delaware Court of Chancery. The MOU is subject to the negotiation of a definitive stipulation of settlement, due notice to our current and former stockholders who are members of the plaintiff class, and approval by the Delaware Court of Chancery. The Company and its directors believe these suits to be without merit, and are pleased to have reached this agreement in principle. If the settlement contemplated by the MOU is not approved by the Delaware Court of Chancery, we intend to deny all the plaintiff’s substantive allegations, and to vigorously defend the litigation.
