Hoku Scientific Announces Progress on Financing Polysilicon Plant

KAPOLEI, HI--(Marketwire - December 5, 2007) - Hoku Scientific, Inc. (NASDAQ: HOKU) today announced that it has signed a non-binding term sheet with Merrill Lynch for Hoku Materials, Inc., its wholly owned subsidiary, to borrow approximately up to $185 million for the construction, procurement and start-up of its planned polysilicon production plant in Pocatello, Idaho. The closing of the loan and the availability of the funds to Hoku Materials is subject to several conditions, including the completion by Merrill Lynch of its due diligence, the negotiation and execution of definitive loan and collateral documents, and the receipt of third-party consents. In addition, prior to receiving any of the loan proceeds, Hoku Scientific will be required to provide Hoku Materials with approximately $35 million in cash for use in the construction of the planned polysilicon plant. To meet this and other capital requirements, Hoku Scientific will be required to secure additional financing.

"Signing this term sheet is a milestone step towards financing the construction of our polysilicon plant," said Dustin Shindo, Chief Executive Officer of Hoku Scientific.

The Pocatello facility is expected to produce approximately 2,500 metric tons of solar-grade polysilicon per year when it is running at full capacity, and the first customer shipments are planned for the beginning of 2009. Hoku recently announced plans for Phase II of its planned polysilicon facilities, which would increase its capacity beyond 2,500 metric tons per year to meet its obligations to Solarfun Power Hong Kong Limited. Hoku began construction in May 2007 of its Phase I, 2,500 metric tons per year, facility, and estimates that total construction costs for Phase I will be approximately $290 million.

In addition to the loan and Hoku's cash contribution, Hoku's customers, SANYO Electric Co., Ltd., Suntech Power Holdings Co., Ltd., Global Expertise Wafer Division Ltd., and Solarfun Power Hong Kong Limited, have committed to prepay a combined total of approximately $240 million for future product shipments to support Hoku's construction and start-up costs. Receipt by Hoku of these prepayments is subject to Hoku's successful completion of specified plant construction, process implementation and production milestones.

This non-binding term sheet will expire on the earlier of the termination of negotiations between the parties or May 31, 2008. In addition, as the term sheet is preliminary and non-binding there may be additional material closing conditions required in connection with any transaction.
