HOUSTON, Jan. 23 /PRNewswire-FirstCall/ — Gundle/SLT Environmental, Inc. (NYSE: GSE) announced today that it has agreed to acquire the stock of Serrot International, Inc. (SII) from Waste Management, Inc. (NYSE: WMI) (WMI) for $30 million. Closing of the acquisition is expected to take place in the next few days.

Under terms of the agreement, GSE will purchase SII, excluding SII’s roofing materials business and certain other assets. The excluded business and other assets are being sold prior to GSE’s purchase of SII or being retained by WMI. The proposed acquisition is subject to, among other things, GSE arranging $80 million of US financing, including $45 million of refinancing, of which approximately $43 million is expected to be outstanding immediately after the acquisition depending upon the amount of cash acquired in the transaction.

For the nine months ended September 30, 2001, GSE reported a net income of $827,000 on revenue of $127.9 million. SII’s retained business revenue was $122.4 million for the same period.

Both GSE and SII are international providers of geomembrane liner systems used in landfills, mining, and industrial applications. GSE has US manufacturing locations in Houston, TX, Spearfish, SD, and Kingstree, SC. SII’s US operations in Henderson, NV and Wellford, SC will be moved to GSE’s US manufacturing plants.

Internationally, GSE has manufacturing locations in Rechlin, Germany, Soham, England, Rayong, Thailand, and Cairo, Egypt. SII has two manufacturing operations in Canada, in one of which it owns 51%. SII also has an 80% interest in an Irish joint venture and a 40% interest in a German joint venture. Both companies have installation operations in the US, Germany and the UK. These installation operations will be combined to provide low cost services to customers.

"These two organizations compliment each other very well," said Samir T. Badawi, GSE’s Chief Executive Officer "With this acquisition, GSE gains access to products it presently purchases and the opportunity to supply SII customers with product that GSE presently manufactures. The consolidation that has taken place within our primary customer base has resulted in increased demand for more cost-efficiency and responsiveness to their needs. We believe this combination should provide us the resources and the economies of scale that will greatly benefit our worldwide customer base by giving them access to the broadest and most cost-effective range of products and services in the industry."
