WHEREAS, SunPower desires to purchase and Jupiter agrees to sell Products (herein defined) pursuant to the terms and conditions of this Agreement.

NOW, THEREFORE, the parties agree as follows:

1. Products. As used in this Agreement, “Product” or “Products” shall mean the polycrystalline silicon manufactured by Jupiter. The specifications for the Product will be mutually agreed by the parties from time to time (the “Jupiter Product Specifications”).

2. Price and Quantity; Purchase Orders.

(a)

Price and Quantity. For the time period January 1, 2010 through December 31, 2016, Jupiter agrees to sell SunPower Products pursuant to the terms and conditions of this Agreement. The price and quantity of Products to be sold to SunPower is as set forth in Exhibit A. Unit prices for shipment of Product are FCA Jupiter, China (Incoterms 2000). Subject only to the price adjustments set forth in Section 3, these prices are fixed for the term of this Agreement. SunPower may require an audit of Jupiter’s supporting documentation validating the price adjustments permitted under Exhibit B. Any such audit shall be conducted by a qualified independent third party who shall be granted access, under a confidentiality agreement, to all relevant documentation it reasonably requests for such verification. Any such audit shall be paid for by SunPower.

(b)

SunPower Purchase Discretion. Notwithstanding anything to the contrary in this Agreement, SunPower assumes no obligation to purchase any Products under this Agreement unless and until SunPower has confirmed, in its sole and absolute discretion, that the Products meet both SunPower’s then current quality standards for the Products (including but not limited to satisfying “N” type ingot manufacturing requirements), and that the Products meet the technical specification criteria agreed to by SunPower. SunPower may modify its quality standards from time to time in its sole and absolute discretion, and may apply such revised standards to any future purchases of Products hereunder.

(c)

Purchase Orders. The parties acknowledge their standard practice in which SunPower, after establishing that the Products have met its then applicable quality standards and the technical specification criteria agreed to by SunPower, may periodically issue purchase orders, and occasionally change orders thereto, for Products requesting specified quantities, delivery dates and delivery locations.

(d)

Right of First Refusal. In the event Jupiter makes commercially available any quantifies of Products in addition to the quantities described on Exhibit A for the periods specified, Jupiter shall provide written notice to SunPower of such availability and the price applicable thereto prior to offering such Products to third parties. SunPower shall have fourteen (14) days to notify Jupiter in writing of its decision whether to accept the offer for all or a portion of such additional Products.

3. Price Adjustments. Jupiter may adjust prices on an annual basis to account for changes in Jupiter’s cost structure relative to the manufacture of the Products, including changes relating to electricity, raw materials and the Employment Cost Index. On January 1 of each year beginning with January 1, 2011, prices may be increased pursuant to the mechanism set forth in Exhibit B.

4. Firm Commitment Agreement. This Agreement is a firm commitment agreement such that SunPower is required to pay for the contracted volume of Products per year over a 7-year period at the prices set forth in Exhibit A, subject to the adjustments described in Section 4 above; provided, however, that notwithstanding the foregoing SunPower shall in no event be required to purchase Products which have not been determined by SunPower to satisfy its quality standards or the agreed technical specifications pursuant to Section 2(b). Subject to the foregoing, in the event that SunPower fails to order and take delivery of its contracted volume in a given year, Jupiter shall invoice SunPower for the differential at full contract price and SunPower will pay the same within 30 days of invoice date. SunPower specifically acknowledges and accepts that it will be liable for the full purchase price of volume differential between the quantity ordered and the contracted volume with respect to Products which SunPower has determined satisfy its quality standards and the agreed technical specifications pursuant to Section 2(b).

In the event that Jupiter fails to deliver Products pursuant to Section 2(a), and such failure is not triggered by a Force Majeure Event or delay in the completion of the NEW Manufacturing Facility described in Section 8, SunPower has the right to purchase the relevant quantity of substitute polysilicon from any third party provider and Jupiter shall immediately reimburse SunPower for the price difference, if any, between the price applicable to the Products Jupiter failed to deliver and the price SunPower has paid the said third party provider.

5. Payment. Payment terms are 6 months in advance of scheduled product shipment for shipments during 2010 and 2011, and net 30 days following the date of the invoice issued upon shipment from 2012. Finance charges of ***% per month (***% per annum) may be assessed on payment past due from the payment due date to the date payment is received. Failure to pay invoices when due or finance charges when assessed may result in delayed or cancelled shipments. No unauthorized deductions from invoices are permitted.

6. Title and Risk of Loss; Packaging; Late Delivery Charges.

(a) Title; Risk of Loss. SunPower shall purchase the Products from Jupiter FCA Jupiter (Incoterms 2000) with title and risk of loss with respect to all Products passing to SunPower when the goods have been delivered to the carrier at Jupiter, China.
