Item 2.03 Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

On March 25, 2010 SunPower Corporation (“SunPower” or the “Company”) entered into a purchase agreement (the “Purchase Agreement”) with Deutsche Bank Securities Inc., Merrill Lynch, Pierce, Fenner & Smith Incorporated, Citigroup Global Markets Inc. and Credit Suisse Securities (USA) LLC as representatives of the several initial purchasers listed therein (collectively, the “Initial Purchasers”), providing for the sale by the Company of $220 million principal amount of 4.5% senior cash convertible debentures due 2015 (the “Debentures”) with a 13 day option in favor of the Initial Purchasers for the purchase of up to an additional $30 million principal amount of Debentures in certain circumstances (the “Overallotment Option”). The Purchase Agreement is filed as Exhibit 10.1 to the Company’s Current Report on Form 8-K dated March 29, 2010 and incorporated herein by reference.

On April 5, 2010 the Initial Purchasers exercised the Overallotment Option in full. SunPower closed the offering of the $30 million aggregate principal amount overallotment option for its 4.5% senior cash convertible debentures due 2015 (the “Overallotment Debentures”) on April 9, 2010 (the “Overallotment Closing”).

In connection with the Overallotment Closing, SunPower entered into additional convertible debenture hedge transactions (collectively, the “Overallotment Convertible Hedge Transactions”) and warrant transactions (collectively, the “Overallotment Warrant Transactions”, together with the Overallotment Convertible Hedge Transactions, the “Overallotment Hedge Agreements”) with certain of the Initial Purchasers or their affiliates. The Overallotment Hedge Agreements are meant to reduce the Company’s exposure to potential cash payments upon conversion of the Overallotment Debentures.

Under the terms of the Overallotment Convertible Hedge Transactions, the Company entered into purchased options with affiliates of certain of the Initial Purchasers, which purchased options cover, subject to anti-dilution adjustments substantially identical to those in the Debentures, 1,331,559 shares of the Company’s class A common stock (the “Class A Common Stock”).

Under the terms of the Overallotment Warrant Transactions, the Company sold to affiliates of certain of the Initial Purchasers warrants to acquire, at a strike price of $27.03 per share, subject to anti-dilution adjustments, cash in an amount equal to the market value of up to 1,331,559 shares of Class A Common Stock. Each Overallotment Warrant Transaction is a separate transaction, entered into by the Company with each option counterparty, and is not part of the terms of the Debentures.

The Overallotment Hedge Agreements are exclusively cash settled. The cost of the Overallotment Hedge Agreements was approximately $1.65 million.

The preceding description of the Overallotment Hedge Agreements Hedge Agreements is a summary and is qualified in its entirety by reference to the confirmations relating to the Overallotment Convertible Hedge Transactions, which are filed as Exhibits 10.1, 10.2, 10.3 and 10.4 hereto and incorporated herein by reference and the confirmations relating to the Overallotment Warrant Transactions, which are filed as Exhibits 10.5, 10.6, 10.7 and 10.8 hereto and incorporated herein by reference.
