Item 1.01. Entry into a Material Definitive Agreement

Credit Agreement

On May 21, 2012 Hoku Corporation (“Hoku”), entered into a credit agreement (the “Credit Agreement”) with China Merchants Bank Co., Ltd., New York Branch (the “Lender”). The Credit Agreement provides for a loan (the “Loan”) in an aggregate principal amount of $5 million. The principal amount of the Loan and any unpaid interest thereon must be paid in full on May 21, 2017 or the tenth business day prior to the date on which the letters of credit expire or otherwise terminate, whichever is earlier. Hoku may prepay the Loan, in whole or in part, at any time without penalty, provided that any such prepayment must be for a minimum of $100,000 and in multiples of $100,000 in excess thereof.

The Credit Agreement includes customary representations, warranties, covenants, acceleration, indemnity, and events of default provisions which may accelerate Hoku’s payment obligations under the Credit Agreement.

The Loan is secured by a standby letter of credit in Renminbi issued by China Merchants Bank Co., Ltd., Chengdu Branch which was procured by Tianwei New Energy Holdings Co., Ltd., Hoku’s parent company (“Tianwei”), in favor of the Lender and which has an aggregate drawable amount of approximately $5.28 million.

The foregoing description of the Credit Agreement does not purport to be complete and is qualified in its entirety by reference to the Credit Agreement, a copy of which is attached as Exhibit 10.1 to this Current Report on Form 8-K and incorporated herein by reference.

On May 21, 2012, in consideration of Tianwei’s procurement of the initial standby letter of credit to secure the Loan under the Credit Agreement, Hoku and Hoku’s subsidiary, Hoku Materials, Inc. (“Hoku Materials”), entered into a Reimbursement Agreement (the “First Reimbursement Agreement”) with Tianwei obligating Hoku to repay Tianwei for, among other things, any reimbursement obligations of Tianwei arising from any draws under the standby letter of credit and all interest, fees and expenses incurred by Tianwei in connection with procuring the standby letter of credit contemplated by the Credit Agreement. In addition, Hoku Materials is guaranteeing Hoku’s obligations to repay Tianwei, and Hoku and Hoku Materials are granting to Tianwei a security interest in all of their fixtures, personal property and real property and all proceeds and products from such fixtures, personal property and real property as security for the payment and performance of all their obligations under the First Reimbursement Agreement.

Amendment No. 1 to Credit Agreement

On May 22, 2012, Hoku and the Lender entered into Amendment No. 1 (“Amendment No. 1”) to the Credit Agreement, dated May 24, 2010 (the “Original Credit Agreement”).

In addition, under Amendment No. 1, the duration of the period specified for the term “Interest Period” was changed from one year to three months and the facility fee was increased to 2.5% from 0.5%. The Lender also waived existing defaults and events of default under the Original Credit Agreement.

In connection with Amendment No. 1, Tianwei has arranged for an extension to the existing standby letter of credit (the “Original SBLC”) in Renminbi issued by China Merchants Bank Co., Ltd., Chengdu Branch, in favor of the Lender and which has an aggregate drawable amount of approximately $20.12 million, which secures the loan under the Original Credit Agreement.
