If recoverable proved reserves in the Guantao are established as a result of the Parties' having deepened the C-3 Well referred to in Section 3.1(a)(i) on a basis in which XCL pays at least one-half of the costs of deepening, sixteen and two-thirds percent (16.667%) of Foreign Contractor's Share of such Guantao reserves shall be included in the computation of reserve value as set out in Exhibit 1. 3.2 XCL and XCL-China covenant and agree to bear two- thirds of the expenditures made and to be made pursuant to the Contract and the Operating Agreement through the Approval Date, and after performance by Apache of its obligations under Article 3.1(a) to continue to bear and pay one-half of the ongoing expenditures incurred by the Foreign Contractor pursuant to the Contract and the Operating Agreement. 3.3 Reimbursement of expenditures made by XCL-China relating to the period prior to the Approval Date which have become the responsibility of Apache pursuant to Sections 3.1(a) or 3.1(b) hereof shall be made by Apache within ten (10) days of the Approval Date. Apache shall be entitled to audit such reimbursable sums and the inventory costs referred to in Section 3.7 below, but any objection thereto must be made within ninety (90) days of the Approval Date. 3.4 For the purposes of Section 3.1(c) above, the determination of reserves shall be made within sixty (60) days of the first sale of oil from a Producing Unit. The engineering staff of Apache and XCL-China shall reasonably attempt jointly to determine the reserve estimates of proved reserves applicable to the Producing Unit(s). In the event the engineering staff of Apache and XCL-China cannot mutually agree to the reserve estimates for a particular Producing Unit within the time specified above, Apache and XCL- China shall accept reserve estimates determined in accordance with Exhibit 1 by the independent engineering firm of DeGolyer and McNaughton, and the cost of the independent determination shall be shared equally by the Parties hereto.

If unpaid after thirty (30) days as set forth above, the balance shall be a debt due and shall at the election of the debtor Party either be payable from the shares of production accruing to the debtor Party or be secured by the guarantee of the parent of the debtor Party. 3.5 Pursuant to Section 2.1(a) of the Participation Agreement, Apache shall pay XCL-China the sum of $196,000 on execution of this Agreement. Effective upon the Approval Date, this sum shall be deemed full and final settlement of all issues between Apache and XCL-China relating to costs incurred by XCL- China under the said Section 2.1(a) of the Participation Agreement, and XCL-China hereby agrees to accept such sum as full settlement. If this Agreement terminates prior to the Approval Date, the said sum of $196,000 shall be deemed to be on account of any sums due by Apache to XCL-China pursuant to the said Section 2.1 (a) of the Participation Agreement and not in settlement thereof.

Following the Approval Date, the said sum or sums of $310,000 paid as provided in the prior sentence shall be a reduction of the reimbursement due by Apache to XCL-China pursuant to Section 3.3 of this Agreement. If the Approval Date occurs before any sum becomes due and payable pursuant to Section 2.1(c) of the Participation Agreement, then notwithstanding the terms of the Participation Agreement, no such sum shall be paid. 3.7 For the purpose of implementing the farmout provisions of Section 3.1 hereof, within seven (7) days of the date of execution of this Agreement, and subject to subsequent audit as referred to in Section 3.3 above, Apache shall purchase XCL-China's two-third's share of the inventory acquired for the Joint Account for the purpose of drilling the wells described in Section 3.1 (a), according to the following procedure: (a) within the above seven (7) days, Apache will verify the existence of usable inventory belonging to the Joint Account which XCL-China represents has an approximate cost basis of $1,500,000. (b) following verification, Apache will pay XCL-China a sum of approximately $1,000,000 representing two-thirds of the cost of such inventory and XCL-China will deliver to Apache a valid bill of sale for such inventory containing the representations and warranties in Section 5.1(f) below, with a mutually acceptable inventory list attached. (c) the above payment of $1,000,000 will be deposited in the Joint Account and shall be used by XCL-China solely towards defraying drilling costs of the D-1 Well. (d) Inventory which has become the sole property of Apache pursuant to subsection (b) above shall be solely used to the extent reasonable and necessary, in the drilling of the D-1 well on the same cost basis as was used for the purpose of subsection (b) above. Apache shall be deemed to have contributed one-third (in terms of cost) of such inventory as and when used, and two-thirds of such cost shall be debited to XCL-China. (e) following the Approval Date, Apache's reimbursement due to XCL-China for two-thirds of the cost of the D-1 well pursuant to Section 3.1(a) above shall be reduced by two-thirds of the cost of the inventory used in such well up to the Approval Date. (f) if a second well covered by Section 3.1(a) above is spudded prior to the Approval Date, the procedure as set out in subsections (d) and (e) above shall apply to the second well until all usable inventory has been exhausted. (g) If this Agreement terminates, XCL-China shall re- purchase from Apache at cost a two-thirds interest in the balance of the inventory not theretofore used in wells, and shall reimburse Apache at cost for two- thirds of the inventory used. (h) XCL-China has been advised that no Chinese value added tax is payable in respect of the inventory transaction contemplated by this Section; however, if value added tax is payable, it shall be the responsibility of XCL- China and Apache will reasonably cooperate with XCL- China to promptly and properly resolve any value added tax questions. 4. APPROVALS AND EFFECTIVENESS 4.1 XCL-China and Apache shall exercise their best efforts promptly to secure the approvals referred to in the definition of "Approval Date" and to obtain execution by the requisite Chinese authorities of a document substantially in the form attached as Exhibit 2. 4.2 Prior to the Approval Date, XCL-China will reasonably include Apache and its personnel in operating activities, including particularly the management of inventory, and will facilitate the changeover of operatorship to Apache on the Approval Date, subject to Section 7.1 below. Following Apache's designation as Operator, XCL-China shall continue to assist Apache in the latter's capacity as Operator to the extent Apache may reasonably request. The Parties will begin work immediately to facilitate the changeover of operatorship to Apache on the Approval Date. 4.3 If at the end of six (6) months from the date of this Agreement, the approvals listed in the definition of Approval Date have not been obtained, any Party may require a further three (3) month period in which to continue to seek the required approvals, by written notice to that effect to the other Parties given at least twenty (20) days prior to the end of the six (6) month period. If prior to the end of such six (6) month period, any Party is officially informed that CNODC's right of first refusal will be exercised or that approval will not be granted, or if at the end of six (6) or nine (9) months as the case may be, the required approvals have not been obtained, this Agreement may at any time thereafter be terminated by any Party on twenty (20) days written notice to the other Parties. 4.4 Apache shall provide XCL-China written notice of Apache's election whether or not to participate in the second phase of the exploration period of the Contract on or before January 31, 1996, and Apache and XCL-China will cooperate together to seek an extension of one year of the relinquishment obligations relating to one exploration block normally arising at the end of the first exploration phase of the Contract. If Apache does not elect to participate in the second phase, it shall be deemed to have satisfied its obligations under Section 3.1(a) hereof at the end of the first exploration phase and shall retain its fifty percent (50%) Participating Interest in any Development or Production Areas granted or applied for pursuant to the Contract, but shall withdraw pursuant to the Operating Agreement from the rest of the Contract Area. In that event, Apache will remain as Operator of the said Development and Production Areas. 5.
