Ms. Adams has over 20 years of experience in the pharmaceutical industry. From 2009 through May 2011, Ms. Adams was with Lundbeck Inc. (the U.S. subsidiary of H.

Ms. Adams' previous work experiences also include time at both TAP Pharmaceuticals and Abbott Laboratories. Ms. Adams earned her MS in Human Resources from Loyola University Chicago and her Senior Professional in Human Resources certification from The Human Resources Certification Institute.

"We are very pleased to have both Sandra Croak-Brossman and Patricia Adams joining us at this exciting time for BioSante," said Stephen M. Simes, BioSante's president and chief executive officer. "Sandy's experience and expertise, particularly in leading Pfizer's Viagra to an FDA approval, will be invaluable in view of the excellent progress we have made in the development of LibiGel for the treatment of female sexual dysfunction (FSD), specifically, hypoactive sexual desire disorder (HSDD) in menopausal women, for which there is no FDA-approved product. Patty has a clear vision for where HR needs to go and how to help BioSante recruit, retain and develop the best talent in the pharmaceutical industry. We remain dedicated to our objective of maximizing stockholder value and believe Sandy and Patty will be integral to this endeavor."
