Arctic Cat 4-Stroke Snowmobiles Certified by U.S. Department of the Interior

THIEF RIVER FALLS, Minn.--Sept. 5, 2003--Arctic Cat Inc. :

-- Arctic Cat First Manufacturer to Certify 2003 and 2004 Models Under New Park Rules

-- Arctic Cat's Park-Certified Sleds Significantly Outperform National Park Requirements

Arctic Cat Inc. today announced that five of its 4-Stroke snowmobiles have received certification for use in Yellowstone National Park and Grand Teton National Park by the U.S. Department of the Interior's National Park Service. Arctic Cat is the first snowmobile manufacturer to receive this annual certification since the Park Service announced new environmental standards in March 2003.

"Arctic Cat pioneered the development of cleaner, quieter four-stroke snowmobile engines, and we are proud to be the first to certify 2003 and 2004 model snowmobiles," said Christopher Twomey, chairman and chief executive officer. "This also is terrific news for snowmobilers, who will now be able to enjoy two of the most popular snowmobile destinations on our four-stroke sleds this winter."

Arctic Cat's certified snowmobiles significantly outperform the National Park Service's emissions standards (see table) and the year 2012 Environmental Protection Agency (EPA) requirements.

To mitigate impacts to air quality and the natural soundscape, the National Park Service requires that recreational snowmobiles entering the parks meet its BAT emissions standards, defined as a snowmobile that achieves a 90 percent reduction in hydrocarbons and a 70 percent reduction in carbon monoxide emissions from the EPA's baseline standards.

"This certification demonstrates our commitment to produce environmentally responsible machines that offer Arctic Cat's unparalleled performance," said Twomey.

The following Arctic Cat snowmobiles meet the National Park Service's new Best Available Technology (BAT) requirements for strict air and sound emissions standards: the 2004 T660 Touring; 2003 4-Stroke Trail and Touring; and the 2002 4-Stroke Trail and Touring models.

Arctic Cat has been developing four-stroke engine technology since 1996. The company was the first manufacturer to offer commercially available four-stroke snowmobiles in the 2002 model year.
