On the terms and conditions set forth in this Agreement, Kunlun Energy intends to transfer to PipeChina, and PipeChina intends to purchase from Kunlun Energy the Target Equity for a cash consideration.

According to the Asset Appraisal Reports, the appraised value of the Target Equity is equal to RMB40,885,718,745. And the record-keeping procedures for the appraisal result have already been completed in accordance with applicable PRC Laws and regulations. The Parties agree that the Transaction Consideration shall be determined on the basis of the appraised value of the Target Equity and subject finally to the profits and losses during the Transitional Period and the adjustments for subsequent events after the Base Date as described in Article 3 herein below.

Both Parties agree that PipeChina shall pay Kunlun Energy the Transaction Consideration in cash in two instalments as follows:

first instalment of Transaction Consideration: Within 20 Days after the Closing Date, PipeChina shall pay Kunlun Energy 85% of the appraised value of the Target Equity, together with the interest accrued thereon from the date immediately following the Closing Date to the date on which such payment arrives at Kunlun Energy’s designated bank account to be calculated at the RMB benchmark interest rate for demand deposits adopted by financial institutions during the same period; and

second instalment of Transaction Consideration: within 15 Business Days after completion of the Closing Audit under Section 3.1, PipeChina shall pay the remaining amount of the Transaction Consideration which shall be equal to (i) the Transaction Consideration finally determined minus (ii) the first instalment of Transaction Consideration paid under (1) above, together with the interest accrued on the remaining amount from the date immediately following the Closing Date to the date on which such payment arrives at Kunlun Energy’s designated bank account to be calculated at the RMB benchmark interest rate for demand deposits adopted by financial institutions during the same period. In the event that PipeChina fails to complete the foregoing agreed payment within the foregoing agreed time limit due to any PRC governmental examination and approval process, the payment due time shall be extended accordingly, but in no event for more than 5 Business Days.

Unless otherwise notified in writing, the details of the bank account to be used by the Parties to receive the Transaction Consideration, liquidated damages or any other amount, as the case may be, payable by the other Party hereunder shall be as set forth below:

Closing Audit. For the purpose of determining the profits and losses of the Target Equity during the Transitional Period and the adjustments for subsequent events after the Base Date, the Parties agree that, within 60 Days after the Closing Date of the Target Equity, they will jointly engage an accounting firm qualified for securities and futures business practice and acceptable to both Parties to perform the Closing Audit, with the audit fee to be equally shared between the Parties.

Ownership of the profits and losses during the Transitional Period. PipeChina agrees that, the profits and losses generated during the Transitional Period attributable to the Target Equity shall belong to Kunlun Energy. Any distributable profits of either Target Company that are declared for distribution during the Transitional Period, if attributable to the Target Equity, shall not be included into the Transaction Consideration. To the extent that as determined in the Closing Audit any net profits are generated by either Target Company during the Transitional Period or the net asset value of either Target Company increases as a result of other profits and losses generated during the Transitional Period, PipeChina agrees that Kunlun Energy is entitled to obtain such increased income through dividend distribution by such Target Company. Resolutions of each Target Company for such dividend distribution shall be declared by the Closing Date (including the very date), and the amount of dividends shall be determined on the basis of the amount of distributable profits attributable to the Target Equity generated during the Transitional Period as specified in the Closing Audit Report. The dividend payment date shall be no later than 30 Days from the date of completion of the Closing Audit. Any amount of such increased income that cannot be obtained by Kunlun Energy through dividend shall be included into the Transaction Consideration, and shall be paid no later than the payment of the second instalment of the Transaction Consideration. In the event that either Target Company suffers a loss or the net asset value of either Target Company decreases as a result of other profits and losses arising during the Transitional Period, Kunlun Energy agrees that PipeChina shall have priority to deduct an amount equal to such decrease from the unpaid Transaction Consideration. To the extent that the unpaid Transaction Consideration is insufficient to cover such loss or decrease, the shortfall shall be paid by Kunlun Energy to PipeChina in cash no later than the payment of the second instalment Transaction Consideration.

Adjustments for subsequent events after the Base Date. Any distributable profits generated by either Target Company before the Base Date that are declared for declaration during the Transitional Period, if attributable to the Target Equity, shall not be included into the Transaction Consideration. To the extent that as determined in the Closing Audit, there is a decrease in the net asset value of either Target Company as a result of the adjustments for subsequent events after the Base Date, Kunlun Energy agrees that PipeChina shall have priority to deduct an amount equal to such decrease from the unpaid Transaction Consideration. To the extent that the unpaid Transaction Consideration cannot cover the decrease, the shortfall shall be paid by Kunlun Energy to PipeChina in cash no later than the payment of the second instalment of the Transaction Consideration. On the contrary, in the event that as determined in the Closing Audit, there is an increase in the net asset value of either Target Company as a result of the adjustments for subsequent events after the Base Date, PipeChina agrees that Kunlun Energy is entitled to obtain such increased income through distribution of distributable profits attributable to the Target Equity. The dividend resolution of each Target Company shall be declared by the Closing Date (including the very date). The dividend payment date shall be no later than 30 Days from the date of completion of the Closing Audit. The amount of dividends declared for distribution during the Transitional Period shall not be included into the Transaction Consideration.

NO ASSIGNMENT

FURTHER ASSURANCE

TAXES AND EXPENSES

Subject to Section 14.2 and unless otherwise provided in this Agreement (or any other Transaction Document), each Party shall legally bear its own costs, fees and any other expenses incurred by it in connection with this Transaction.

Considering the fact that Kunlun Energy is an offshore company and is therefore subject to certain restrictions including foreign exchange control in terms of payment of domestic PRC Taxes, PipeChina agrees to withhold and pay on behalf of Kunlun Energy the withholding tax for transfer of properties in China imposed in relation to this Transaction payable by Kunlun Energy. For that purpose, PipeChina may deduct from any amount of the Transaction Consideration payable such withholding tax in accordance with applicable PRC tax laws and regulations. After written confirmation by Kunlun Energy, PipeChina will declare and pay as Kunlun Energy’s withholding agent to competent tax office(s) under the State Administration of Taxation of the PRC the withholding tax for transfer of properties in China imposed in relation to this Transaction and go through the overseas payment filings, including having necessary consultations or discussions with relevant tax authorities, in connection with which, Kunlun Energy shall render necessary assistance and cooperation. Within three Business Days after any payment of any amount of tax on behalf of Kunlun Energy as described above, PipeChina shall be obligated to provide Kunlun Energy with the tax returns and tax payment certificates. Any and all the costs and expenses incurred by PipeChina in connection with its acting as the withholding agent of Kunlun Energy under this Article, including without limitation, fees and expenses incurred in the engagement of any tax advisor to handle the payment of relevant Taxes and charges on behalf of Kunlun Energy, shall be borne by Kunlun Energy.

For purposes of this Transaction, unless as otherwise provided in laws or regulations and/or otherwise agreed between the Parties, all fees, costs and expenses incurred in connection with the handover of the Target Equity shall be reasonably apportioned by the Parties and settled through negotiation.

Both Parties agree that the tax costs of the Target Equity shall be transferred together with the Target Equity. For the avoidance of doubt, from and after the Closing Date, to the extent that either Target Company suffers a claim of tax deficiency brought by any competent tax authority and incurs any additional tax liability as a result, such additional tax liability shall be borne by such Target Company then existing. Where Kunlun Energy or PipeChina is required to pay any underpaid tax or late payment penalty in connection therewith, such issue shall be resolved through amicable consultations between the Parties.
