Mohammad Reza Vaghari was convicted on February 24, 2011 in a U.S. District Court for illegal business transactions with Iran allegedly between 2002 and 2008. Vaghari's co-conspirator, Mir Hossein Ghaemi, pleaded guilty to charges in November 2010. Vaghari and Ghaemi, both Iranian nationals, used their Pennsylvania-based business Saamen Company to purchase goods with military uses from U.S. companies for export to Iran, using Dubai as a transshipment point. Items shipped without required licenses included fuel cell systems, ultrasonic liquid processors, computers, ultrasound machines and other laboratory equipment. Ultimate recipients allegedly included the Pasteur Institute of Iran and Tarbiat Modarres University in Tehran, both listed in Japanese, German, and British warning lists as entities of concern for biological, chemical or weapons of mass destruction proliferation.
