LINCOLNSHIRE, Ill. -- BioSante Pharmaceuticals, Inc. (Amex: BPA) announced today that it has received notification from The NASDAQ Stock Market LLC([R]) that BioSante's common stock is approved for listing on The NASDAQ Global Market. BioSante's board of directors approved the decision to switch the listing of BioSante's common stock from The American Stock Exchange to The NASDAQ Stock Global Market LLC([R]). BioSante currently is going through all the required regulatory processes associated with the switch and expects its common stock to begin trading on NASDAQ under the symbol BPAX in early to mid-November 2007. BioSante's common stock will continue to trade on the American Stock Exchange under its current symbol BPA until such date.

"This decision was reached after careful consideration of capital market alternatives and an analysis of the electronic market model, which provides increased visibility and liquidity to our investors," said Stephen M. Simes, BioSante's president and chief executive officer. "We wish to thank The American Stock Exchange as well as our specialist on AMEX, Cohen Specialists, for the years of support and orderly trading."

"We believe that NASDAQ's electronic multiple market maker structure will provide BioSante with enhanced exposure and liquidity, while at the same time provide investors with the fastest execution and lowest cost per trade," said Phillip Donenberg, BioSante's chief financial officer. "This makes the move to NASDAQ a logical step and we expect a very orderly transfer."
