Bally Technologies Announces Deal With Trump Entertainment Resorts to Supply eTICKET(TM), Bally Power Technology at 3 Atlantic City Casinos

Bally Technologies, Inc. (NYSE: BYI) announced today that it has signed a contract with Trump Entertainment Resorts, Inc. (Nasdaq: TRMP) ("Trump") for Bally Power Promotions(TM), Bally Power Winners(TM) and Bally eTICKET to replace existing two-wire ticket-in / ticket-out systems at three Atlantic City casinos covering more than 8,000 slot machines.

Trump Entertainment Resorts selected eTICKET to enhance the player experience at the Trump Taj Mahal, Trump Marina and Trump Plaza resort locations. Bally Power Promotions will allow Trump Entertainment Resorts to offer its players downloadable promotional slot credits. Bally Power Winners will allow Trump Entertainment Resorts to build and offer custom random progressive jackpots across all of its slot floors. Both of these new technology products for Trump Entertainment Resorts require regulatory approval.

Virginia McDowell, Executive Vice President and Chief Information Officer of Trump Entertainment Resorts, said: "Selecting eTICKET and replacing our existing two-wire ticketing system was a natural choice for us. Bally Power Promotions fits in very well with our planned marketing programs by giving us the ability to offer our guests downloadable promotional credits right at the game."

"We chose Power Promotions because we believe it will help us continue to raise the level of excitement on our casino floors," said Jeanne-Marie Wilkins, Vice President of Business Strategy of Trump Entertainment Resorts. "We believe this technology will enhance our guests' experience and add value to our customer loyalty program."

The three properties are scheduled to complete the conversion to eTICKET by the end of 2006, bringing Bally's worldwide count of eTICKET machines to more than 200,000.

"We are now moving toward a 100-percent market-share position in Atlantic City with our single-wire ticketing technology by replacing previous two-wire ticketing systems," said Tom Reilly, Vice President, Eastern Region System Sales for Bally. "This consolidates accounting into the Bally SMS system, subsequently increasing customer-service levels while at the same time providing an enhanced level of operational efficiencies that couldn't be achieved with a separate ticketing system."

Recognized as the industry systems leader with more than 345,000 machines and 652 casino, bingo, Class II, central determination and lottery locations worldwide -- including more than 174 locations currently running Bally eTICKET(TM) on more than 200,000 slot machines -- the Bally Technologies systems product line offers slot machine cash monitoring, table management, cashless, accounting, security, maintenance, marketing, promotional and bonusing capabilities, enabling operators to accurately analyze performance and accountability while providing an enhanced level of customer service.
