Hoku Announces Amendment to Polysilicon Plant Engineering Contract With Stone & Webster


POCATELLO, Idaho, Feb. 24, 2009 (GLOBE NEWSWIRE) -- Hoku Materials, Inc., a wholly owned subsidiary of Hoku Scientific, Inc. (Nasdaq:HOKU), established to manufacture and sell polysilicon for the solar market, today announced that it entered into a change order agreement under its engineering, procurement and construction management services contract with Stone & Webster, Inc., to clarify the scope of on-going work for Hoku's planned 4,000 metric tons per year polysilicon production plant. Stone & Webster is a subsidiary of The Shaw Group Inc.

The change order confirms Hoku's intent to delay the detailed engineering and construction of a portion of the polysilicon plant, the trichlorosilane (TCS) production plant area, until April 2009 and reassign construction management services to JH Kelly, LLC, Hoku's general construction contractor. JH Kelly has been primarily responsible for construction management over the past several months because they have controlled the critical path schedule on-site in Pocatello. The revised Stone & Webster scope of work includes the engineering and procurement that is required for Hoku to commercially operate the plant using third party TCS, and the scope to transition operations from third party TCS to on-site TCS production in a closed-loop production process.

"The revised scope of work is consistent with our plan to start-up the plant and commence shipments to our customers in the second half of 2009, which may be before our TCS plant is operational," said Dustin Shindo, chairman and CEO of Hoku Scientific. "Because the engineering of our TCS plant has been substantially completed by Dynamic Engineering, Inc., Stone & Webster is well positioned to resume the detailed engineering work for our TCS plant when our cash flow supports this investment. Our earlier ordering of long lead-time items, such as fluidized bed reactors and distillation columns, allows us to suspend this work for a few months without disproportionately impacting the final completion schedule."

The change order also realigns the schedule guarantees in the contract around the revised scope of work, and Stone & Webster's engineering and procurement deliverable dates.

"As we head into the home stretch, our company remains fully committed to fulfilling Hoku's engineering and procurement requirements to ensure the successful operation of this polysilicon plant," said Lou Pucher, president of Shaw's Energy & Chemical Group.
