Changzhou, China: Trina Solar Extends Long-Term Polysilicon Supply Agreement

Trina Solar has extended its eight year long-term supply agreement with Jiangsu Zhongneng Polysilicon Technology Development Co. Ltd, a subsidiary of GCL-Poly Energy Holdings Limited by another five years. Initial delivery of polysilicon to Trina Solar started in April 2008.

Under the adjusted terms of this agreement, the total consideration will remain unchanged from the combined total of the original and supplemental agreements signed in 2008, whereas additional polysilicon and wafer deliveries will be provided starting in 2016 for a five year period at pre-determined shipment volumes and prices. The agreement also contains a price adjustment clause that offers a market-linked price formula. GCL-Poly will supply the Company with high-quality polysilicon and wafers sufficient to produce approximately 8,500 MW of solar modules over 13 years. Wafer deliveries to commence in 2010 are expected to support production above the Company's in-house integrated manufacturing capabilities to address growing customer demand.

"We are very pleased to strengthen our long-term relationship with GCL-Poly by further extending the tenure of the agreement," said Jifan Gao, Trina Solar's Chairman and CEO. "This extension will provide a stable source of high-quality materials as well as support our cost reduction initiatives to solidify our position as a high-quality global integrated PV manufacturer."

"We are pleased to extend our business relationship with Trina Solar whom we value as a strategic long-term customer," said Mr. Zhu Gong Shan, Executive Director, Chairman and CEO of GCL-Poly. "We look forward to continue delivering high-quality polysilicon and wafers on schedule through 2020."
