Item 1.01

Entry into a Material Definitive Agreement.

Third Amendment to First Amended and Restated Supply Agreement with Wuxi Suntech Power Co., Ltd.

On May 12, 2008, Hoku Materials, Inc., a wholly-owned subsidiary of Hoku Corporation (“Hoku Materials”), and Wuxi Suntech Power Co., Ltd. ("Suntech") entered into a First Amended and Restated Suntech Supply Agreement (the “Restated Suntech Supply Agreement”), as disclosed by us in a Current Report on Form 8-K filed on May 12, 2008. On July 6, 2009, Hoku Materials and Suntech entered into an amendment to the Restated Suntech Supply Agreement (“Amendment No. 1”). On June 29, 2010, Hoku Materials and Suntech entered into a second amendment to the Restated Suntech Supply Agreement (“Amendment No. 2”). On February 29, 2012, Hoku Materials and Suntech entered into a third amendment to the Restated Suntech Supply Agreement (“Amendment No. 3”, and the Restated Suntech Supply Agreement as amended by Amendment No. 1, Amendment No. 2 and Amendment No. 3, the “Amended Suntech Supply Agreement”).

Pursuant to the Amended Suntech Supply Agreement, Hoku Materials and Suntech agreed to reduce the amount of polysilicon to be delivered to Suntech. The fixed pricing terms were deleted, and the parties agreed to negotiate pricing on a quarterly basis by reference to the average spot market price index for raw polysilicon.

In addition, Amendment No. 3 extended the date by when Hoku Materials must commence shipments until October 31, 2012. The Amended Suntech Supply Agreement will automatically renew for an additional 12 months after the initial term (and each renewed term) with the same terms unless one party terminates or the parties mutually agree to amend the Amended Suntech Supply Agreement. The Amended Suntech Supply Agreement also specifies the timing and volume limitations of each purchase order and delivery. If Hoku Materials notifies Suntech that it cannot deliver the amount specified in the purchase order, Suntech has the right to terminate the Amended Suntech Supply Agreement or increase the quantity of polysilicon for the next monthly delivery. Hoku Materials will have no obligation to ship polysilicon to Suntech prior to October 31, 2012, and Suntech may terminate the Amended Suntech Supply Agreement if Hoku Materials has failed to commence shipments by such date, in which case we would be obligated to refund the $2 million prepayment.

The foregoing description of Amendment No. 3 and the Amended Suntech Supply Agreement is only a summary and is qualified in its entirety by the text of the Amendment No. 3, a copy of which will be filed with our Annual Report on Form 10-K for the fiscal year ending March 31, 2012, by the text of the Restated Suntech Supply Agreement, a copy of which was filed as Exhibit 10.72 to our Annual Report on Form 10-K for the fiscal year ended March 31, 2008, by the text of Amendment No. 1, a copy of which was filed as Exhibit 10.105 to our Periodic Report on Form 8-K filed on July 10, 2009, and by the text of Amendment No. 2, a copy of which was filed as Exhibit 10.63 to our Annual Report on Form 10-K for the fiscal year ended March 31, 2010.
