SIERRA SPORTS "CHUTING" STAR PAVES THE WAY
Unique Sponsorship Agreement Has Sierra Sports Brand Coming Out of the Chutes

EUGENE, OR - September 8, 1999 - Sierra Sports, premier publisher of simulated PC sports, breaks the mold and becomes the first software company to sponsor cowboys in the Professional Bull Riders, Inc. 1999 Bud Light Cup Tour season. This innovative sponsorship builds on Sierra Sport's relationship with the Professional Bull Riders, Inc, Ty Murray , Tuff Hedeman and more than 40 additional top riders on the tour that are an integral part of Sierra Sport's upcoming PC game release, Professional Bull Rider. Casey Gates, currently ranked 10th in 1999 PBR Bud Light Cup Tour points standing and Donnie Ray Howard, currently ranked 32nd will don the red, black and gold colors of Sierra Sports.

The Sierra Sports gold star will be shining on the chaps, shirts and gloves of Gates and Howard for the next five events leading up to the PBR Bud Light Cup Finals in Las Vegas. During the Finals in Las Vegas, not only will Gates and Howard be wearing the Sierra Sports colors, but so will 7-time World-Champion All Around Cowboy, Ty Murray. With all the events, including the PBR Finals, being nationally televised, the Sierra Sports brand will be coming out of the chutes into homes nationwide. This
solidifies the pledge the company has made to the rodeo genre by bringing the Professional Bull Rider product and the name "Sierra Sports" directly to the fans.

"Sierra Sports has made a significant commitment to the category of rodeo and our first PC game release, Professional Bull Rider, will show fans just how committed we are to delivering quality games to a large and growing audience." Says Sean Gleason, Director of Marketing. "Our sponsorship of Casey and Donnie Ray give us the opportunity to show fans from week
to week that we intend to be an integral part of the sport."

Sierra Sports has teamed up with the PBR and has been taking the Professional Bull Rider Interactive Booth on the road to the events leading up to the finals and bringing the virtual bull riding action straight to the fans. During the PBR Finals event in Las Vegas, Sierra Sports will have a major presence during all four action-packed days. The Sierra Sports colors will be seen all over Las Vegas - from the Western Gift Expo to the actual events to the after parties. Interactive booths will be set-up for fans to try Professional Bull Rider and take a spin on a 2,000 pound virtual bull to see if they can make the 8 seconds.
