Manufacturing & Quality Focus On December 5th, the Company initiated a voluntary recall of select lots of Protandim. We are committed to producing safe, scientifically validated products. “Reputational Capital” is an operational imperative and is earned with business transparency and high ethical standards. Based on what we know today, potential gross cost impact is $7M (1). ~$3.5 M for material disposition and replacement. ~$2.5 M for shipping replacement product. ~$1.0 M for other voluntary recall related expenses. 18 Estimate as of December 5, 2012

Manufacturing & Quality Focus What have we done? Hired an independent GMP expert to evaluate our processes and provide process recommendations Enhanced manufacturing processes with multiple redundancies, some of which now exceed industry standards The redundant processes include: Additional filtering process at the raw material stage, beyond what is performed at the raw material supplier Magnet at the powder stage prior to tableting Metal detector post tableting Metal detector post bottling 19 “The likelihood that any one tablet of Protandim® will contain a small piece of wire is extremely low. Even if ingested the likelihood that the small pieces of wire would result in any adverse health event is also extremely low.” David W K Acheson MD, FRCP (Leavitt Partners) Dr. Acheson is an internal medicine physician and was former Associate Commissioner for Foods at the FDA and Chief Medical Officer at the FDA Center for Food Safety and Applied Nutrition.
