Reigning Rockstar Energy Drink U.S. Open Champion James Stewart Ready to Defend his

AURORA, Ill. (July 10, 2007) – Reigning Rockstar Energy Drink U.S.  Open Champion
James Stewart, of Haines City, Fla., announced today  that he will defend his title
inside Las Vegas’ MGM Grand Garden  Arena October 12-14 against the world’s top
supercross racers.

“I love the whole atmosphere of the U.S. Open, the lights, being  indoors and just
putting on a good show for the fans,” said  Stewart. “After all, we are in Vegas
where there are always big  winners.”

Stewart’s entry not only stages his title defense, it places him in  line to
accomplish a feat that has only been done once before. Only  15-time AMA National
Champion Ricky Carmichael has won  championships in Amp’d Mobile World Supercross GP,
Amp’d Mobile AMA  Supercross Series, AMA Motocross, Motocross des Nations and the 
U.S. Open in the same season.

Earlier this year Stewart captured his second Amp’d Mobile World  Supercross GP title
and his first AMA Supercross title. On his way  he collected his 13 AMA Supercross
wins, giving him 24 career AMA  Supercross wins. He currently sits second in AMA
Motocross behind  Carmichael, who will not contest the entire series.

Last year Stewart swept both nights of racing en route to his first  Rockstar Energy
Drink U.S. Open.
