- Will Exercise Right to Purchase Remaining 25 Percent Interest -

DAYTONA BEACH, Fla. - November 1, 2006 - International Speedway Corporation (NASDAQ Global Select Market: ISCA; OTC Bulletin Board: ISCB) ("ISC") today announced it has entered into a purchase agreement with Indianapolis Motor Speedway Corporation to indirectly acquire an additional 37.5 percent interest in Raceway Associates, LLC ("Raceway Associates"), owner and operator of Chicagoland Speedway and Route 66 Raceway in Joliet, Illinois. The purchase price for the transaction is approximately $69 million in cash.

After the transaction closes, ISC will own 100 percent of Motorsports Alliance, LLC ("Motorsports Alliance"), which owns 75 percent of Raceway Associates. Raceway Associates was formed in 1999 as a joint venture between Motorsports Alliance and the former owners of Route 66 Raceway. Raceway Associates subsequently developed Chicagoland Speedway, a 75,000 seat facility hosting premier motorsports events from the NASCAR NEXTEL Cup, NASCAR Busch, IRL IndyCar and ARCA RE/MAX series.

ISC will also exercise its right to purchase the minority partners' remaining 25 percent interest in Raceway Associates pursuant to the 1999 Raceway Associates formation agreement. All the above transactions are expected to close in early 2007.

"Chicagoland is a uniquely attractive asset well-positioned in the nation's third largest media market," said ISC President Lesa France Kennedy. "The region boasts a strong motorsports fan base, demonstrated by six consecutive years of season ticket sell-outs at the facility since opening in 2001. Our active representation on Raceway Associates' management committee and extensive knowledge of the business will help ensure a seamless integration into ISC."

"During the past six years, it has been a great privilege to have worked with both International Speedway Corporation and Indianapolis Motor Speedway, leaders in the motorsports industry," said Matt Alexander, vice president and general manager of Chicagoland Speedway. "As we move forward, we are very excited about working more closely with ISC to continue to grow motorsports in and around the Chicagoland area. We feel that this transaction provides us with a great opportunity to utilize all of the valuable resources ISC has to offer in an effort to exceed our fans expectations on a regular basis."
