new compressed natural gas (CNG) delivery trucks today at its Brooklyn, NY beverage

thing to do.  Our investment in clean fuel vehicles will help improve New York City’s air and
ease our reliance on foreign oil.”  MBD—the largest single-market beer distributor in the
country—delivers beer to bars, restaurants, supermarkets and hotels in the New York
metropolitan area and has a fleet of over 500 vehicles, including 300 beverage delivery trucks.

holds approximately 42 gallons (diesel gallon equivalent) of natural gas.  “The success
ofManhattan Beer Distributors’ CNG program shows that private fleets can incorporate
cleaner, natural gas engines in their day-to-day operation in a cost-effective and reliable
way”, said Alex Bell, Vice President, Bell Power Systems.

MBD has been given several awards recognizing its leadership in the use of clean fuel
vehicles, including the “Beverage World Magazine 2005 Fleet of the Year” award, the “2005
