3.1.                                  The total purchase quantity of polysilicon converted from the quantity of silicon wafers and polysilicon purchased by Party B in 2010 is 3,900 tons, of which Party B undertakes to purchase 150MW polysilicon wafers at the unit price of [****]† yuan/pc since March, i.e. 38,960,000 pieces based on the temporary calculation standard of 3.85 w/pc; 930 tons of polysilicon based on the temporary standard of 6.2 g/w. Then the remaining purchase quantity of polysilicon is 2,970 tons, at a unit price of [****]† yuan/kg as prescribed in Supplementary Agreement II. As for the polysilicon wafers to be purchased in March and April 2010, both parties agree that Party A shall supply Party B with no fewer than 2 million pieces of polysilicon wafers each month, and the short thereof shall be made up during the period from May to December 2010.

 

3.2.                                  Party B undertakes to purchase 300MW of polysilicon wafers in 2011, and the quantity of polysilicon to be purchased shall be subject to Exhibit B-3 hereto.

 

3.3.                                  Both parties undertake that on the precondition that the total amount under the Original Contract shall not be decreased, the annual quantity of polysilicon to be purchased during 2012 to 2015 shall be subject to Exhibit B-3 hereto, and the quantity of silicon wafers to be purchased shall be temporarily subject to Exhibit B-3 hereto. In case either party requests to amend the purchase quantity of silicon wafers, such party shall submit a written application for amendment to the other party in the third quarter of the prior year, and the actual purchase quantity shall be otherwise negotiated by both parties. If both parties need to amend the purchase quantity of silicon wafers, the minimum quantity of polysilicon wafers to be purchased by Party B shall be 400MW for 2012, 500MW for 2013, 600MW for 2014 and 700MW for 2015 respectively. If the amended purchase quantity of polysilicon wafers each year falls short of the quantity set out in Exhibit B-3, the short shall be converted to polysilicon and purchased by Party B in such year. If such amendment results in the total purchase amount less than the amount set out in Exhibit B-3, Party B undertakes that it shall annually make up for the insufficient purchase amount of polysilicon wafers by equal shares during 2016 to 2020.

 

4.                    The silicon price adjustment process under this Agreement shall follow the provisions set out in Article 9 of Supplementary Agreement II. In addition, when the yearly or quarterly price of silicon wafers hereunder during such year or quarter as provided by this Agreement has decreased by [****]†% or more, or increased by [****]†% or more, compared with the current market price, both parties may initiate the price adjustment process as prescribed in Article 9 of Supplementary Agreement II. In case that the price of silicon wafers fluctuates as a result of the innovation of silicon wafer processing technologies, etc., the price thereof shall be otherwise negotiated by both parties.

 

†                 This portion of the Supplementary Agreement No. 4 to Polysilicon Supply Agreement has been omitted and filed separately with the Securities and Exchange Commission, pursuant to Rule 24b-2 under the Exchange Act of 1934.

5.                    Any extra profits gained from technical cooperation between both parties shall be shared by both parties through friendly consultation. If any advance of battery technology requires adjusting the thickness of silicon wafers, Party B shall make adjustment to the current thickness of 200 μm +/-20 μm. The silicon wafers yield rate shall rise by one piece with the thinning out of every 10 μm of wafer thickness. The price of silicon wafers then shall be otherwise negotiated.

 

6.                    The indicators of silicon wafers, such as the appearance and quality, shall comply with the specifications agreed upon by both parties in Product Specification attached hereto, and the indicator of electrical property shall meet the manufacturing requirement of Party B (i.e. Party B requires that the electrical property conversion efficiency of silicon wafers produced by Party A should at least equal the average electrical property conversion efficiency of silicon wafers produced by a third party silicon wafer provider of Party B, or the electrical property conversion efficiency of silicon wafers self-produced by Party B during the same purchase period. Party A is entitled to choose either of the foregoing electrical property conversion efficiency as the manufacturing requirement of Party B). If any dispute in connection with quality arises, it shall be determined by a third party jointly designated by both parties. Such determination of the third party shall be subject to Sub-Article 6, Article 4 of Supplementary Agreement I. Any amendment to the quality indicator shall be subject to Article 3.4 of the Supply Contract dated March 29, 2008.
