Notwithstanding the foregoing, the Parties agree to cooperate in good faith to improve the quality of the Wafers to be supplied with the agreed specifications and minimizing breakage rates provided that if the improvement of quality of the Wafers results in an increase in production cost, the Seller is not obliged to supply such Wafers with improved quality unless their new price has been agreed in writing by the Parties.

II.2 Quantity and Price.

(a) Target Purchase Quantities. During each Contract Year, the Buyer agrees to purchase and the Seller agrees to supply over the course for a period of three months each (each a “Quarter”) during each Contract Year the quantity of Wafers (such quarterly purchase quantity commitments, measured in number of wafers, the “Quarter Quantity”), at the prices set forth in Schedule B hereto.

(b) Prices. All prices are based on EXW China basis. The prices set forth in Schedule B hereto are on a RMB per wafer basis, exclusive of any freight costs, insurance or other delivery costs or any Taxes in respect of the Wafers, which shall additionally be paid by the Buyer.

The Parties agree that should any change in Laws pertaining to Taxes in the PRC happen (other than Taxes relating to income and profit of the Parties generally) and (i) such change results in an increase in production costs of Wafer of the Seller, or (ii) such changes result in new or additional costs or expenses to the Buyer other than those already in existence that the Buyer is liable to pay to the Seller as at the date of this Agreement, the Parties will discuss and renegotiate the Prices within a period of *** subsequent to the change, in order to take into account the effects of the above changes. Should the Parties not reach an agreement after the above period of ***, the Party that suffers for the increase in costs or Taxes (as the case may be) will have the right to terminate this Agreement by serving a *** notice in writing to the other Party, unless the other Party shall agree to bear the relevant increase in costs, in which case neither Party shall be entitled to terminate this Agreement. Notwithstanding the foregoing, the Parties shall continue to perform their respective obligations under this Agreement until such time the new Prices have been agreed or this Agreement has been terminated.

The Parties agree that should any change in Laws pertaining to Taxes in the PRC happen (other than Taxes relating to income and profit of the Parties generally) and such change results in a reduction in production and/or administrative costs of Wafer of the Seller, the Parties will discuss and renegotiate the Prices within a period of *** subsequent to the change, in order to take into account the effects of the above changes. Should the Parties not reach an agreement after the above period of ***, the Party that would not benefit from a reduction in Prices as a result of the reduction in production and/or administrative costs shall have the right to terminate this Agreement by serving a *** notice in writing to the other Party, unless the other Party shall agree to reduce the Prices in the sum equivalent to the reduction in production costs of Wafer of the Seller as a result of the change in the relevant Laws, in which case neither Party shall be entitled to terminate this Agreement. Not withstanding the foregoing, the Parties shall continue to perform their respective obligations under this Agreement until such time the new Prices have been agreed or this Agreement has been terminated.

(d) Monthly Planning, Rolling Forecast. For planning purposes only, no later than the *** of each calendar month, the Buyer shall deliver to the Seller a forecast of the quantities of Wafers that the Buyer anticipates that it will order from the Seller over ***. Such estimated amounts in the forecasts shall have no effect on the Buyer’s obligation to purchase some or all of the Buyer’s Quarter Quantity for any Quarter of a Contract Year or the Seller’s obligation to deliver the indicated quantities, unless confirmed pursuant to the procedures of Article II.3.

II.3 Purchase Orders and Order Acknowledgements.

(a) Purchase Order. The Buyer shall issue a written purchase order to the Seller through fax or internationally recognized carrier on a monthly basis at a minimum.

The Seller Order Acknowledgements shall reference the applicable Buyer purchase order. Until the Seller has provided the Buyer with the Seller Order Acknowledgement, such purchase order shall not be deemed to have been accepted by the Seller.

(b) Binding Purchase Orders. Unless expressly agreed to in writing by the Parties, no additional or different terms or conditions contained in any quotation, sales order, acknowledgement form, purchase order or other communication from the Seller or the Buyer shall be binding upon either the Party. To the extent that there is a conflict among the terms and conditions of this Agreement, any Buyer purchase order and any Seller Order Acknowledgement, the terms of this Agreement shall apply.

II.4 Seller Invoices.

Seller invoices shall reference the applicable Buyer purchase order and the Seller Order Acknowledgements and shall be submitted by the Seller to the accounts payable address of the Buyer specified in writing from time to time by the Buyer. To the extent that there is a conflict between the terms and conditions of this Agreement and any such invoice, the terms of this Agreement shall apply.
