New Ideas Win Modine Long Term Partnership with International and ``Diamond Supplier'' Award

RACINE, Wis.--Feb. 2, 20043, 2004--Modine Manufacturing Company announced today it has been awarded a major contract with International Truck and Engine Corporation, providing all its power train cooling systems starting in 2007. This is in addition to the engine cooling, heating and air conditioner systems (HVAC) for all Blue Diamond LCF (Low Cab Forward) trucks, a program scheduled to launch in early 2005. Because of Modine's design, research, and follow-through, International Truck and Engine designated Modine a "Diamond Supplier" for its power train cooling, and HVAC systems, an honor bestowed on only a small percentage of suppliers.

"This is great for Modine, solidifying a successful partnership with International. Because of our 13 year relationship with International we understand how to launch programs on budget, on time, meeting the specifications that our customers require," said Scott Bowser, Modine's General Sales Manager of the Truck Division. "This will extend our partnership into at least 2010,"added Bowser.

The emissions program starting in 2007 will include all International heavy, medium and Blue Diamond trucks. International continued this partnership because of Modine's ability to adapt to new business practices. "Modine utilizes world class, best practices in production, design, quality, and delivery, becoming an extension of our own engineering and assembly facilities," said Paul Olejniczak, International Supply Manager - Purchasing and Logistics.

The Blue Diamond Truck will include a module with some of Modine's latest state of the art heat transfer technology. The system will have an aluminum CF (counter flow) evaporator that was derived from Modine's extensive research and development of CO2 air conditioning systems. The new CF evaporator has 50% less weight than round tube/plate fin evaporators commonly used in truck applications. It also consumes 40% less space than standard round tube/plate fin product.

"It's lighter and takes up less space, a perfect combination for the low cab forward truck," according to Bowser. The HVAC module, consisting of a radiator, charge air cooler, and a frame, will be produced in the "Just in Sequence" system that Modine has perfected over the years. Modine began the "Just in Sequence" process in car manufacturing, and has won several national honors from its Toledo, OH facility. Deliveries there are 100% on time, and have a near perfect rate for acceptance.

The condensers for International are made at Modine's McHenry, Illinois facility, the radiators from the Trenton, Missouri plant, the charge air coolers from Lawrenceburg, Tennessee and the oil coolers from Nuevo Laredo, Mexico.

International gives the "Diamond Award" for attaining a new level of commitment and dedication to the business. "Modine reached this status by being the cooling systems solutions leader, by bringing new products to market, by committing to continuous improvement, and by delivering products designed to delight the customer," said Ann Farrell, Vice President-Purchasing, International.

At Modine we are turning ideas into solutions. "We're proud of the honor. We earned it by working with International over the years, and making their business goals, our business goals," said Bowser.
