Subject to the satisfaction of certain legal conditions, the tender offer is scheduled to be consummated at the end of October, unless extended. In support of the tender offer, Mr Michael HAGAN, FURON's chairman, President and Chief Executive Officer, has agreed to tender all of his shares of FURON common stock to NORTON in the tender offer. FURON's Board of Directors has recommended unanimously that its shareholders accept the Norton offer and tender their shares. High performance plastics are engineered polymer materials that offer specific properties of electrical, mechanical or thermal resistance; chemical purity or corrosion or wear resistance in demanding environments. They are replacing more traditional materials and find applications in very diverse industries such as electronics, aerospace, automotive, medical, food and beverage. NORTON Performance Plastics, a division of the Industrial Ceramics Branch of SAINT-GOBAIN, has, on a pro forma basis for 1999, $350M in sales for a wide variety of value-added applications: adhesive foams, seals and bearings, ultra-pure flexible tubing, technical films and composites. It has experienced annual internal growth exceeding 7% over the last 8 years. The acquisition of FURON will create a global leader in performance plastics with an unmatched portfolio of technologies and applications. FURON and NORTON Performance Plastics, having technical and commercial complementary features, will be able to supply a wider range of products to their customers, especially in light of FURON's strong presence in the US and NORTON's position in Europe and Asia. On a pro forma basis for calendar year 1999, the combined businesses should have sales of $830M and 5,500 employees in more than 50 locations. After the completion of the transaction, SAINT-GOBAIN expects to rapidly implement substantial technical, industrial and commerical synergies in the US and Europe. This acquisition will be earnings enchancing for SAINT-GOBAIN as early as the year 2000.
