SAN DIEGO, July 9 /PRNewswire/ --

Gen-Probe Incorporated (Nasdaq: GPRO) announced today that the Company does not intend to increase the value of its conditional tender offer to acquire 100% of the outstanding shares, warrants and convertible bonds of Innogenetics (EBR: INNX), a Belgian molecular diagnostics company.

"We believe the disciplined analytical process we used to value Innogenetics resulted in a full and fair offer, and a higher bid therefore does not make financial sense for us," said Hank Nordhoff, Gen-Probe's chairman and chief executive officer. "Our existing clinical diagnostics and blood screening businesses remain healthy year-to-date, and we continue to focus on growing them in the United States and internationally."

Gen-Probe is making this statement in response to a higher bid made today by Solvay Pharmaceuticals S.A.
