International Monetary Systems Processes $6 Million in November Trade Volume

Record month's revenue up 39% over last year

New Berlin, Wis., December 20, 2005 -- International Monetary Systems, Ltd. (OTC BB: INLM), a worldwide leader in business-to-business barter services, today announced that its gross revenue for November shattered all previous records. The company processed more than $6 million worth of trades, which produced gross revenue of $696,000. This represents an increase of 39% over the same period in 2004.

Don Mardak, President and CEO of INLM commented: "The past several months have shown a consistent pattern of growing revenues for our company, and November was especially spectacular. Our first six-million-dollar month of trade volume, and nearly $700,000 in revenue, established a new standard for us. And what makes the trade volume even more impressive is the fact that we count just one side of each transaction in our totals. Most other barter companies combine their sales and purchases when reporting their numbers. Combining sales and purchases, our November trade total would be more than $12 million. A great deal of credit for our increased transaction volume goes to our experienced brokers who create trade velocity by uncovering the needs of their clients and generating sales for them. We expect our growth pattern to continue well into 2006."

International Monetary Systems generates revenue through enrollment fees of $595 per new client, monthly account maintenance fees of $12 cash and $12 trade, plus transaction fees of 12% in cash, usually paid 6% by the buyer and 6% by the seller. For the past several years, IMS has been systematically acquiring other trade exchanges in an ongoing consolidation of the barter industry.
