Evergreen Solar Announces Expansion Plans for EverQ Using Quad Technology

Business Wire, Oct 25, 2007

Partners Agree to an Initial Public Offering Framework for EverQ

MARLBORO, Mass. -- Evergreen Solar, Inc. (Nasdaq: ESLR), a manufacturer of solar power products with its proprietary, low-cost String Ribbon[TM] wafer technology, announced today that Evergreen Solar, Renewable Energy Corporation ("REC"), and Q-Cells, equal partners in EverQ, have approved the construction of a third integrated wafer, cell and panel facility and that the partners have begun planning an initial public offering for EverQ.

The new EverQ facility will open in early 2009 in Thalheim, Germany, cost approximately EUR 125 million, net of government grants, and increase EverQ's production capacity from 100 MW to approximately 180 MW. The partners also agreed to expand EverQ's production capacity to approximately 600 MW by 2012.

To support the further growth ambitions of EverQ to 600 MW, REC has offered an additional supply agreement for polysilicon of approximately 4,000 MT beginning in 2010 and continuing through 2015 at market pricing competitive with long-term contracts. Total polysilicon volumes supplied by REC to EverQ under the existing and new agreements could potentially reach 2,100 MT per year.

EverQ to License Evergreen Solar's Quad Technology

The new EverQ facility will license Evergreen Solar's revolutionary Quad furnace technology with its state of the art automated ribbon cutting technology. This innovative wafer production process provides substantial opportunity to further increase yield, cell efficiency and labor productivity as well as to further reduce String Ribbon's already industry-leading silicon consumption. EverQ will pay a market-based royalty to Evergreen Solar for its current Quad technology based on actual cost savings realized by EverQ's use of Evergreen Solar's Quad technology.

"The agreement to use Evergreen Solar's proprietary Quad furnace technology to expand EverQ's production capacity further validates the unique value proposition that our String Ribbon technology offers to our customers and our joint venture partners," said Richard M. Feldt, Chairman, President and Chief Executive Officer of Evergreen Solar. "Combined with our own aggressive expansion plans to reach 500 MW of capacity by 2012, EverQ's growth plans will make String Ribbon one of the leading technologies in the photovoltaic industry."

IPO Planned for EverQ

Although the specific timing of an IPO is still to be determined, Evergreen Solar, REC, and Q-Cells have executed a binding memorandum of understanding detailing the required steps to prepare EverQ for its IPO.

As part of the preparations for the IPO, the management and organization of EverQ will be significantly strengthened to build EverQ into an independent company. The sales and marketing organization at EverQ will be expanded as the distribution of solar panels produced by EverQ will ultimately be marketed under a yet-to-be determined brand name. In the interim, EverQ will continue to provide Evergreen Solar-branded product to honor all current and future Evergreen Solar customer contracts and commitments until the transition is completed. At the same time, Evergreen Solar will work with EverQ management to develop a customer-focused marketing transition plan.

"We believe that the solar industry will remain robust and continue to experience rapid growth over the next several years," said Feldt. "Evergreen Solar will capitalize on the strength of our String Ribbon technology by rapidly expanding internally and through our licensing arrangement with EverQ."

At the time of the IPO, Evergreen and EverQ will enter into a five year market-based royalty-bearing cross license to share all new material technology development on Evergreen Solar's String Ribbon platform.
