MEI started selling TSCM equipment and related products to the German military intelligence service (known as “MAD”), in the 1960s. The sales were made through a middleman from the mid 1970s. In or around April 1983, Dirk Ekkehard Zoeller, an officer of MAD, contacted Mason seeking to eliminate the middleman. Zoeller was responsible for procurement, testing, inspection and acceptance of TSCM equipment on behalf of MAD. On July 13, 1984, MEI and Zoeller entered into a written contract, which provided that MEI would pay Zoeller a 13.3% commission on every sale of MEI equipment to MAD. Three years later, Zoeller and Mason also agreed that MAD would grant exclusive “general alignment” service contracts to MEI in exchange for a 50-50 fee split.
Over a period of five years, Zoeller granted MEI over $1.4 million in equipment and service contracts and received over $225,000 in return. During the course of the conspiracy, Zoeller also provided information and guidance on the amount MEI should charge to MAD for its equipment and services. MEI used this information to artificially inflate its prices to MAD.
