YaSheng Group, Inc. (OTC:YHGG) have signed a letter of intent dated November 17, 2004 for the acquisition by YaSheng of 80% of Sustainable Systems, LLC ("Sustainable") http://www.sustainableinc.com/site/index.htm . Under the terms of the letter and upon closing of the transaction, which is anticipated for early 2005, the companies have agreed that Sustainable will become a division of YaSheng and continue its focus on domestic and international development of bio-refineries that convert agricultural and waste materials into substitutes for petroleum based products. In addition, the company will continue to research, develop and commercialize bio-based fuels, lubricants, specialty chemicals and other bio-based products.

Sustainable Systems, LLC is a Missoula, Montana based research, development, and commercialization company that holds provisional patents and proprietary formulations and processes for biobased fuels, lubricants, and specialty chemicals. They currently market two branded renewable diesel fuels Montana Biodiesel(TM) and PacBio(TM) in blends of 2%, 5% and 20% as well as 100% neat renewable diesel fuel. The fuel requires no changes to the existing fuel infrastructure, no engine modifications, provides enhanced lubricity, reduced emissions and is competitively priced against conventional petroleum diesel. Based in the Pacific Northwest, the combined company will be positioned to expand manufacturing operations, agricultural producer relationships, and retail pump presence. The company anticipates developing and building a scalable bio-refinery in Washington State with a projected annual output of 253,000 tons of finished product with a weighted average market value of $501 per ton.

"We are very excited to have moved forward with the YaSheng Group. We have a common value system and vision that is focused on maximizing the potential of agricultural and waste raw materials to fill emerging market demands. Our timing is excellent and the combination with YaSheng will enable us to commission the first bio-refinery in the Pacific Northwest, expand our domestic and global development strategy, and continue to move discoveries off the bench-top and into commercial production," stated Paul T. Miller, Managing Member of Sustainable Systems.

"We are please to announce the potential partnership between YaSheng Group and Sustainable Systems. This partnership will utilize YaSheng Group’s massive Agricultural production and Sustainable Systems refinery technology as we further our global expansion efforts while focusing on our core business of Agriculture and Chemicals," stated M. Ping, President of YaSheng Group.
