Business Cooperation Agreement

Both Parties agree that, in consideration of the services provided by Party A, Party B shall pay to Party A the fees (the “Service Fees”) equal to [100%] of the after-tax income determined by U.S. GAAP of Party B, provided that upon mutual discussion between the Parties and the prior written consent by Party A, the rate of Service Fees may be adjusted based on the services rendered by Party A in that quarter and the operational needs of Party B. All out-of-pocket expenses (including without limitation the travelling expenses, accommodation, transportation, printing and postage fees etc) that Party A may incur as a result of the provision of the Services hereunder shall be solely borne by Party B. The Service Fees shall be due and payable on a quarterly basis; within 15 working days after the beginning of each quarter, Party B shall (a) deliver to Party A the management accounts and operating statistics of Party B for such quarter, including the after-tax income of Party B during such quarter (the “Quarterly Income”), and (b) pay [100%] of such Quarterly Income, or other amount agreed by Party A, to Party A (each such payment, a “Quarterly Payment”).

Unless the Parties agree otherwise or the law provides otherwise, the Service Fees payable by Party B hereunder shall not be subject to any deduction or set-off (e.g. bank handling fees etc). The management report, operation data and financial statements provided by Party B shall be true, valid, accurate and complete. If Party A suffers any losses as a result of any defect of the aforesaid documents, Party B shall be fully responsible for such losses. In the event that Party B’s payment obligation hereunder is reduced or released because of the provision by Party B of any fraudulent materials to Party A, Party B hereby irrevocably undertakes to compensate Party A accordingly for the amount so reduced or released.

Business Cooperation Agreement

如果在乙方有义务向甲方支付服务费时，根据美国一般公认会计准则确定乙方处于亏损状态，甲方需要合并乙方的亏损，并有义务向乙方支付亏损额，以弥补其亏损。

If Party B is operating at losses determined by U.S. GAAP when Party B is obligated to pay the Services fees to Party A, Party A needs to absorb Party B’s losses and be responsible and required to reimbursement Party B for those losses.
