Wells Fargo Teams with Convergence Ethanol on $300,000,000 Funding

Business Wire, June 6, 2006

LOS ANGELES -- Convergence Ethanol(TM) Corp. "CE", a MEMS USA Company (OTCBB:MEMS), has exclusively retained Wells Fargo Bank, N.A. to place $300,000,000 in securities. These funds will be for CE's woodwaste-to-fuel-grade-alcohol refinery in Northern Ontario, Canada. The refinery is being built on a 720 acre site of Hearst Ethanol One which is owned by CE with a minor ownership interest by C. Villeneuve Construction Company Ltd. The refinery will: (a) make 120,000,000 gal/yr of 110 octane number, fuel-grade alcohol; (b) diversify the economy of Northern Ontario; and (c) reduce Canada's transportation fuel costs.

Wells Fargo has been providing banking and financial services for more than 150 years. They are the largest financial institution headquartered in the western United States. Forbes ranks Wells Fargo as the world's 25th leading company. Wells Fargo Capital Management economists are known for their investment strategies, macro-economic forecasts, and other top-down analysis.

Canada, a signatory to the Kyoto Protocol, is the world's top producer of forest products. It generates enough woodwaste to more than meet ALL of Canada's motor fuel needs while simultaneously reducing greenhouse gas emissions. Ontario now offers tax incentives equal to US$0.85/gallon of alcohol and has mandated the use of alcohol in all motor gasoline beginning in 2007.

Construction of this bio-refinery is targeted for completion within 30 months. The operating refinery will employ 230 as well as improve opportunities for traditional forest industries that are seeking environmentally friendly methods of woodwaste disposal.

CE and Wells Fargo will continue to pursue Canadian provincial and federal government backed loan guarantees to support private sector equity and debt for this clean-energy project.
