NEWS RELEASE

HABASIT TO ACQUIRE SUMMA INDUSTRIES

FOR $15.00 PER SHARE IN CASH

September 1, 2006

Reinach-Basel, Switzerland and Torrance, California USA

Habasit Holding AG, a privately held Swiss company, and Summa Industries (NasdaqGM: SUMX) today jointly announced that they have entered into an agreement and plan of merger for a wholly-owned subsidiary of Habasit to acquire Summa Industries via a cash tender offer for all outstanding shares of Summa common stock. The boards of directors of Habasit and Summa have unanimously approved the offer, and the board of directors of Summa will unanimously recommend that Summa stockholders accept the offer and tender their shares.

Under the terms of the agreement, a wholly-owned subsidiary of Habasit will commence a cash tender offer to acquire all of the outstanding common stock of Summa at a price of $15.00 per share. The offer represents a 76% premium to yesterday’s closing price of $8.51 per share of Summa common stock on the Nasdaq Global Market, and a 62% premium to the average of the high and low prices of Summa common stock for the three month period ended August 31, 2006.

Consummation of the offer is subject to the prior satisfaction of several conditions, including, among others, receipt of US and foreign regulatory approvals and the tender to Habasit of not less than a majority of the then-outstanding Summa shares in the tender offer.

Following consummation of the tender offer and the satisfaction of customary closing conditions, including regulatory and other standard approvals, Habasit will acquire Summa in a cash merger, with Summa becoming a wholly-owned subsidiary of Habasit, and any remaining Summa shares not tendered in the offer, other than dissenting shares, will be entitled to receive the same cash consideration of $15.00 per share in the merger. In connection with the transaction, Habasit will assume approximately $21 million in existing indebtedness of Summa.

Mr. Giovanni Volpi, Chairman of Habasit AG, said “I am delighted to be able to expand the U.S. operations of Habasit, particularly in the conveyor belt products, where Habasit is the global leader. All of the management of Summa Industries and its subsidiaries will remain in place and existing U.S. operations will continue. We intend to invest to improve operating efficiencies and customer service and to strengthen relationships with Summa’s customers and distributors.”

Commenting on the transaction, Mr. James R. Swartwout, Chairman of the Board and Chief Executive Officer of Summa, said “Habasit will be a good parent corporation for Summa Industries. With financial strength, global reach, world-class manufacturing systems, and a culture of innovation and outstanding customer service, Habasit will support continuing growth and operating improvement at Summa.”
