WARRENVILLE, Ill. (March 17, 2008) Continuing to grow its share of orders for Mine Resistant Ambush Protected (MRAP) vehicles, Navistar Defense won a contract from the U.S. Marine Corps Friday for additional International® MaxxPro™ MRAP vehicles valued at more than $410 million. The company, formerly known as International Military and Government, LLC, is a wholly owned affiliate of Navistar International Corporation (Other OTC: NAVZ).

The new order of 743 increases Navistar’s total Category I MRAP vehicle orders to 5,214; current production levels are at 500 vehicle units a month. The company has delivered 2,000 MaxxPro MRAP vehicles to the military. Navistar’s overall MRAP vehicle orders total more than $3 billion since the first contract was awarded in May 2007.

MaxxPro MRAP vehicles are designed to protect troops from roadside bombs and other threats. Presently, there are more than 1,500 MaxxPro MRAP vehicles in theater.

“Navistar’s worldwide service network, manufacturing power and family of truck and engine products offers the U.S. military and our allies tremendous scale,” said Archie Massicotte, president of Navistar Defense, LLC. “Building and servicing the MaxxPro MRAP is a privilege because this is about protecting our troops so they can fulfill their missions safely.”

To meet the demands of changing mission requirements calling for increased protection and payload capacity, Navistar introduced its recently updated Category I MaxxPro MRAP vehicle called the MaxxPro Plus.

“Our close collaboration with the military enables us to swiftly adapt the MaxxPro to overcome threats and other challenges faced by the troops in theater,” said Massicotte.

As orders continue for these vehicles, Navistar has delivered nearly 120,000 parts pieces, components and other field support services to keep MaxxPro MRAP vehicles in theater mission ready. Parts and service awards from the military thus far total more than $300 million. Additionally, nearly $80 million in truck orders including water and fuel tankers were awarded to the company in recent months by the military.

Navistar has nearly 1,000 dealership locations worldwide with facilities in 75 countries outside North America, including Iraq and Afghanistan.
