Crane Cams Signs Multi-Year Partnership as Official Partner of All World Racing Group Properties.

CONCORD, N.C. -- Crane Cams[R] and the World Racing Group (OTCBB:DMSP) announce that Crane Cams has become an Official Partner of all WRG properties -- including the World of Outlaws[R], World of Outlaws Late Model Series(SM), Advance Auto Parts Super DIRTcar Series[TM], and DIRTcar[TM] Racing sanctioning body.

The partnership is a defining moment for WRG as it is the first time a corporate partner has secured marketing rights with every WRG owned property, including official rights with the three national touring series and weekly sanctioning body, media rights, interactive rights, and WRG owned track rights. The partnership will run through 2010 with option years that could extend it even longer.

"This partnership is broad reaching for Crane Cams," says Lance Harris, CEO of Crane Cams. "It is multi-pronged. We absolutely want to reward and recognize engine builders by creating the Crane Cams Engine Builders Challenge, awarding prize money to the winning engine builders in each touring series. We also want to recognize the racers as Crane Cams becomes a contingency and marketing partner across all the touring series. The new TV partnerships with SPEED and ESPN will give Crane Cams a great platform to reach out to dirt racing fans all across the country and world. And for the fans, many of whom are racers and Crane Cams customers themselves, we are going to work very closely with WRG to be an active partner adding to the event experience."

Crane Cams' involvement includes title ownership of the Crane Cams Engine Builders Challenge for all three touring series, title sponsorship of the Crane Cams Dash in World of Outlaws events, interactive participation with WorldofOutlaws.com, signage at all events, and advertising on SPEED and ESPN networks in conjunction with World of Outlaws event coverage.

"With this new four-year partnership, Crane Cams is making a significant commitment to dirt track racing," says Rob Butcher, World Racing Group Chief Marketing Officer. "The Crane Cams Engine Builders Challenge will be a great prize and sense of pride for engine builders in all three touring series. The Dash, already one of the most exciting parts of a World of Outlaws event, just got even better with Crane Cams support and prizes. Crane Cams is also becoming a key partner of our SPEED and ESPN television broadcasts. In addition, Crane Cams is helping us develop fan promotional ideas. In every sense, Crane Cams is a total WRG partner that is enthusiastically embracing all of our assets."

Be sure to tune in at 2 p.m. on Sunday, May 13, when the World of Outlaws debut on SPEED.
