Convergence Ethanol, Inc. Updates Shareholders on Progress.

LOS ANGELES -- Convergence Ethanol(TM) Corp., a MEMS USA Company (OTCBB:MEMS), California-based developer of biorenewable energy projects and provider of professional engineered systems to the energy industry, updated shareholders today on the progress of its operations.

Convergence Ethanol's mission is to support the energy industry in producing cleaner burning fuels. Each of three company operating divisions has a specific eco-energy focus: (1) ethanol refinery development; (2) selling engineered products; and (3) engineering, fabrication and sale of eco-focused energy systems. ISO 9001:2000-certified, operating divisions have served customers throughout the energy sector since 1952.

The intersection of political pressure, environmental concern and technological advancement has created a unique opportunity for progress in the energy industry. Under the leadership of James A. Latty, PhD, PE (President, CEO) and Daniel K. Moscaritolo (COO, CTO), Convergence Ethanol is currently developing projects that will enable the industry to achieve its energy goals.

The company's first biorenewable energy project is a woodwaste-to-ethanol refinery in Hearst, Ontario Canada. This project has four objectives:

--Create a viable alternative energy enterprise;

--Displace consumption of fossil fuels;

--Improve the environment; and

--Produce biorenewable ethanol at a substantial profit.

The refinery will use modern catalytic processing, as used in oil refineries, to synthetically convert organic woodwaste into ethanol. This convergence of technologies will enable the continuous production of fuel-grade ethanol in high volume, at low cost. All motor gasoline sold in Ontario must contain at least 5% ethanol by 2007, with the goal of 10% by 2010. This refinery could service approximately 22% of the Ontario demand.

Woodwaste, an abundant waste stream of local forest industries, is a non-food raw material for making ethanol -- an advantage helping to ensure consistent supply and reliable cost. The 720-acre refinery site houses a licensed repository containing 2 million tons of woodwaste, sufficient supply for 240 million gallons of ethanol.

Ethanol is the world's most used alternative liquid fuel. Worldwide demand is more than double production capacity and grows at over 25% per year.

The Board of Directors of California MEMS USA, Inc., a California corporation ("CA MEMS"), a wholly owned subsidiary of MEMS USA, Inc. Nevada, voted to amend CA MEMS' Articles of Incorporation changing its name to "Convergence Ethanol(TM) Corp." (See press release dated April 5, 2006.) This transaction is expected to be complete within the next 30 days.
