Navistar Wins $71.5 Million Contract to Provide Parts and Support for MaxxPro™ with Marine Corps MRAP Vehicles

Warrenville, Illinois - September 13, 2007

Navistar International Corporation (Other OTC: NAVZ) announced today that its military affiliate, International Military and Government, LLC, has won a contract from the U.S. Marine Corps for $71.5 million to provide parts support for the Marine Corps’ International® MaxxPro™ mine-resistant ambush protected (MRAP) vehicles.

The contract builds on the more than $1 billion in total contracts the Navistar unit has previously announced to deliver 1,971 MaxxPro units to the Marine Corps. The MaxxPro is designed to protect troops from roadside bombs, improvised explosive devices and other threats.

“This contract award reflects positively on our track record for providing parts to support our durable vehicles,” said Daniel C. Ustian, Navistar’s chairman, president and chief executive officer. “This order is vitally important to the protection of our country’s military personnel. Our goal is to assure that this life-saving technology reaches the troops as soon as possible.”

Archie Massicotte, president of International Military and Government, LLC said: “Providing solid support after delivery is essential – it’s what we did with the more than 160,000 commercial vehicles we built in 2006. We have the expertise, infrastructure and global supply network to keep the MaxxPro™ vehicles mission ready.”

Contents of the parts kits range from 90-day supplies of basic on-the-road necessities such as filters to additional parts and accessories that typically need updating within a year.

“This contract is important to Navistar and our Parts organization,” said Phyllis Cochran, senior vice president and general manager, Navistar Parts. “Parts availability is critical to keeping trucks up and running and we consider it our duty to provide outstanding parts support to the military. We will work very closely with our suppliers to deliver quality parts to keep these vehicles ready to serve our troops.”

Navistar Parts has distribution centers in strategic locations worldwide and is dedicated to maximizing vehicle uptime for its customers.

The company also confirmed that it has fulfilled its August delivery commitment of 77 MaxxPro™ MRAP vehicles for the U.S. military and is well underway producing vehicles scheduled for delivery in September.
