King Pharmaceuticals Acquires Exclusive Rights to EpiPen(R) In Canada

BRISTOL, Tenn., March 2 /PRNewswire-FirstCall/ -- King Pharmaceuticals, Inc. (NYSE: KG - News) announced today that it has acquired from Allerex Laboratory Ltd. the exclusive rights to market and sell EpiPen® (epinephrine injection) in Canada. EpiPen® is an auto-injector that administers epinephrine, the definitive emergency treatment for severe anaphylaxis.

King is the leading manufacturer of auto-injectors for the self- administration of injectable drugs, including EpiPen®. Approximately 2% of the population in Canada is estimated to have allergic sensitivities placing them at risk for anaphylaxis, and that number is increasing, especially with respect to children. Net sales of EpiPen® in Canada totaled approximately $21.2 million in 2004.

"Thousands of adults and children benefit from EpiPen®, the number one prescribed self-administered treatment for life-threatening anaphylaxis," said Steve Andrzejewski, Chief Commercial Officer of King Pharmaceuticals. "We are excited to expand our existing EpiPen® franchise to include the rights to market and sell this emergency self-administered product in Canada. This is part of our strategy to pursue commercial opportunities for our branded prescription pharmaceutical products in Canada and throughout the world."

Anaphylaxis is a severe allergic reaction that some individuals experience in response to certain foods, including peanuts, medications, insect venom or latex. Anaphylaxis can be fatal within minutes if untreated. EpiPen®, when administered at the first sign of anaphylaxis, can provide individuals the time necessary to obtain more definitive emergency treatment.

King will pay Allerex $25 million plus an earn-out based on sales of EpiPen® in Canada. The worldwide rights to the distribution of EpiPen® are licensed exclusively to Dey, L.P. of Napa, California. Allerex serves as Dey's exclusive EpiPen® sub-distributor in Canada.
