The lead investor was Prax Capital (“Prax”), a China-focused private equity fund that invests in the Company through its solely owned investment vehicle Dragon State International Limited.

“We are delighted to add Prax Capital as a strategic shareholder,” stated Chungfeng Tao, Chairman and Chief Executive Officer of Keyuan. “With a successful track record of helping emerging companies and extensive network of entrepreneurs and investors in China, Prax will be a tremendous financial and strategic asset to Keyuan. While we have adequate capital to meet our growth plans, the $20.3 million investment gives us supplementary financial flexibility to secure additional raw materials at favorable prices to run through our recently increased production projection of 660,000 metric tons.”

Keyuan will invest the $20.3 million of new capital to generate incremental revenues and profits. The Company recently raised its 2010 guidance by approximately 20% to $550 million revenues and $36.3 million net income. The Company is confident in reaching its full year numbers. Management will also provide an update to its fiscal 2010 financial guidance and 2011 guidance when the Company reports third quarter results in November 2010.

Keyuan recently announced that the Company commenced construction of the first Styrene-Butadiene-Styrene (“SBS”) production facility in Ningbo, Zhejiang Province on September 1st. The new SBS facility will be located adjacent to its current production facility and is expected to add 70,000 metric tons to Keyuan’s production capacity by the end of 2011. The new facility is anticipated to achieve 80% utilization rate in 2012, the first full year of production, and generate approximately $110 million of sales and $10 million to $11 million of net income in 2012.

As part of the financing, Mr. Lei Xu (Michael), a partner of Prax Capital, will join Keyuan’s board of directors. Prax is a private equity fund focusing on growth capital investments in China. Michael joined Prax Capital in 2003, and has been primarily responsible for leading the investment team in sourcing, evaluating and executing deals, including the investments in Suntech and Little Sheep.

Michael holds an MBA degree from the Wharton School at the University of Pennsylvania and a law degree from Ningbo University in China. The addition of Mr. Xu brings the total number of independent board directors to four.

“We are very attracted by Keyuan’s unique technology and its entrepreneurial management team; a rare combination in the petrochemical sector in China,” said Mr. Xu. “We look forward to a long-term partnership with Mr. Tao and his team to grow Keyuan into a leading non-State-owned petrochemical company in China.”
