ARTICLE 5. DRILLING AND DEVELOPMENT 5.1 PROSPECT MEETINGS At any time after the execution of this JVA and during the term of this JVA, any Party may initiate the process of proposing a Prospect Well by calling for a meeting ("Prospect Meeting"). Unless otherwise agreed, the Prospect Meeting shall be called by notice to the Non-Proposing Party (which notice shall be in writing, shall designate the time and place of the Prospect Meeting and shall be delivered to the Non-Proposing Party at least ten (10) days prior to the Prospect Meeting). The Party who called the Prospect Meeting shall present its planned Prospect Well Proposal at the Prospect Meeting. 5.2 PROSPECT WELL PROPOSALS At any time at, during, or after a Prospect Meeting, either Party ("Proposing Party") may make a Prospect Well Proposal by written notice to the other Party ("Non-Proposing Party"). The Prospect Well Proposal should be similar to that presented at the Prospect Meeting, but may be revised or modified. 5.2.1 Such proposal shall include: i) a description of the geological lead(s) or objective(s) to be evaluated ("prospective formation"); and ii) a plat detailing the Prospect Area; and iii) the proposed surface and bottomhole location of Prospect Well Proposal; and iv) the total depth of the deepest prospective formation ("total depth") within the structure or anomaly to be tested by the Prospect Well Proposal; and v) a detailed AFE setting out the itemized costs and expenses of drilling and logging the test well to total depth; and, vi) a unit plat or acreage allocation plat depicting the separate tracts covered thereby for cost sharing purposes, in the event the Prospect Area is not owned uniformly by the Parties so as to cause the Parties to have different interests in the test well. Notwithstanding the above, unless otherwise agreed by the Parties, at least eighty percent (80%) of a Prospect Area must be under lease, either by the 4 <PAGE> Parties, or third-party lessees in order for either Party to propose and designate a Prospect to the other Party. 5.3 PROSPECT ELECTION The Non-Proposing Party shall have thirty (30) days after receipt of the Prospect Well Proposal to give written notice to the Proposing Party of its election to participate or not participate in the drilling of the Prospect Well ("Participation Election Date"). 5.4 PROSPECT OPERATIONS Except as otherwise provided herein, or in the Operating Agreement, the costs, risk and expense of the Parties in operations hereunder shall be based on the Participation Interest. All operations hereunder shall be governed in accordance the terms and conditions of that Operating Agreement attached hereto as Exhibit "D" and made a part hereof. The Parties shall execute the Operating Agreement simultaneously with the execution hereof. Unocal shall be designated Operator under the Operating Agreement. In the event of a conflict between the terms and conditions of this JVA and the Operating Agreement, the terms and conditions of this JVA shall prevail. 5.5 INITIAL TEST WELL FOR A PROSPECT Notwithstanding anything to the contrary in the Operating Agreement, in the event that a Party does not participate in the Initial Test Well of a Prospect Area, then upon commencement of Actual Drilling Operations thereon, the non-participating Party shall assign, or forfeit rights to (in the event that Unocal has not earned an assignment of the associated leasehold) all of its leasehold interest in and to the Prospect Area to the participating Party; however, in no event shall a Party be required to assign leasehold to the extent that same is currently producing from another Prospect Area. Additionally, Ivanhoe, as a non-participating Party, shall not be required to assign all of its leasehold interest in and to the Prospect Area until Unocal has otherwise earned leasehold rights to the Exploratory Area in accordance with Article 6 hereinbelow. 5.6 FAILURE TO PROCEED If Actual Drilling Operations are not commenced for the Prospect Well within one hundred and twenty (120) days from the Participation Election Date, the Prospect Proposal shall be deemed to not have been made and the leasehold within the former Prospect Area shall again be subject to the terms and provisions of this JVA. ARTICLE 6. EARNING EVENTS 6.1 UNOCAL RIGHTS TO ASSIGNMENT OF IVANHOE LEASEHOLD Unocal shall earn Ivanhoe Leasehold on an Exploratory Area by Exploratory Area basis until such time as the Settlement Date is reached: On the Settlement Date, Ivanhoe shall immediately assign to Unocal its proportionate share of the Ivanhoe Leases not already assigned to Unocal in the same manner as set forth in Section 3.1 hereinabove. 6.2 WELL DRILLED WITHIN EXPLORATORY AREA Prior to the Settlement Date, except as provided in Section 6.4 hereinbelow, Unocal shall earn an assignment of its proportionate share of the Ivanhoe Leases to the extent that said leases lie within an Exploratory Area by participating in a Prospect Well drilled therein through the successful completion of same through the wellhead, or through the plugging and abandonment of same in the event the well is completed as a dry hole (the "Earning Event"). 6.3 WELL DRILLED UNDER CRESLENN RANCH JOINT VENTURE Prior to the Settlement Date, Unocal shall earn an assignment of its proportionate share of the Ivanhoe Leases situated within an otherwise unearned Exploratory Area by participating in any well drilled under the Creslenn Ranch Joint Venture agreement in which Ivanhoe has opted to have Unocal carry its interest therein pursuant to Section 4.3 hereinabove. The Exploratory Area to be earned by Unocal shall be the Exploratory Area not already earned by Unocal based on the following priority: i) Lone Star Exploratory Area 5 <PAGE> ii) Catfish Creek Exploratory Area iii) Malakoff Exploratory Area iv) Phoenix Exploratory Area v) Loudy Exploratory Area vi) SW Athens Exploratory Area vii) NE Cayuga Exploratory Area 6.4 EARNING CLARIFICATION The intent of the Parties is that prior to the Settlement Date Unocal shall earn one Exploratory Area for every Prospect Well in which it participates through the Earning Event. The Parties recognize that an Exploratory Area associated with a Prospect Well Proposal could have previously been earned by Unocal by virtue of Section 6.3 hereinabove, or by virtue of a previous Prospect Well drilled in said Exploratory Area to which Unocal participated. Therefore, Ivanhoe agrees that as to any Prospect Well in which Unocal participates through the Earning Event, Unocal shall earn an assignment of its proportionate share of the Ivanhoe Leases to the extent that said leases lie within the associated Exploratory Area, or if already earned, then the next unearned Exploratory Area based on the priorities set forth in Section 6.3 hereinabove. ARTICLE 7. AREA OF MUTUAL INTEREST 7.1 ESTABLISHMENT/DURATION Effective as of the Effective Date, Unocal and Ivanhoe do hereby establish Areas of Mutual Interest ("AMI") covering those certain areas as outlined in red on Exhibit "E." Notwithstanding termination of this JVA, the AMI shall terminate on December 31, 2005 and be of no further force and effect unless the AMI is terminated sooner by mutual agreement of the Parties. 7.2 ACQUISITION/OPTION Should any Party acquire, directly or indirectly, a Mineral Interest affecting any lands located, fully or partially, within the AMI, such Party (the "Acquiring Party") shall immediately give written notice thereof to the other Party (the "Non-Acquiring Party"), together with all pertinent details and information, including copies of all instruments of conveyance (including but not limited to, copies of leases, assignments, subleases, farmouts and other contracts affecting the Mineral Interest), copies of paid drafts or checks and itemized invoices of the actual costs incurred by the Acquiring Party, including any bonus, administrative fees, brokerage, legal, and recordation costs and any other direct costs (said actual costs are referred to as "Acquisition Costs"), an AMI Cost Allocation (if so required) and all other available data pertaining to the acquisition of the Mineral Interest. If the Mineral Interest is located partially outside of the AMI and/or within a Prospect Area, the Acquiring Party shall also prepare and submit an allocation of the portion of Acquisition Costs attributable to the portion of the Mineral Interest located within the AMI ("AMI Cost Allocation"), to be calculated on a surface acre basis. The Non-Acquiring Party shall have thirty (30) days, or forty-eight (48) hours if a rig capable of performing the operation is on location, from receipt of such notice to elect in writing to acquire its proportionate interest in the Mineral Interest by paying its proportionate share of the cost and assuming its proportionate share of the obligations. If two or more offerings are made in the same notice by the Acquiring Party, the Non-Acquiring Party shall have a separate right of election as to each such interest. Failure to respond by the deadline stated herein shall be deemed an election not to participate in the acquisition as described in said notice. Failure to pay said proportionate share of costs within sixty (60) days following an election to participate shall result in a forfeiture of the Non-Acquiring Party's interest with the same effect as if said Party had initially elected not to participate. If less than all Parties elect to participate in said acquisition, the lands and/or depths covered by any such Mineral Interest shall be excluded from the AMI and the Mineral Interest acquired shall not be subject to this JVA; however, said interest shall be subject to an operating agreement substantially in the form as the Operating Agreement. 7.3. PAYMENT/ASSIGNMENT If the Non-Acquiring Party elects to participate in such acquisition it shall pay to the Acquiring Party its proportionate share of the Acquisition 6 <PAGE> Costs or, if applicable, its proportionate share of the AMI Cost Allocation for such interest, within sixty (60) days after receipt of an invoice for said costs. Upon receipt of said payment, the Acquiring Party shall execute and deliver to the Non-Acquiring Party an assignment of the interest due the Non-Acquiring Party, utilizing a form similar to the form attached hereto as Exhibit "C," pursuant to which the Non-Acquiring Party shall bear and assume its proportionate share of all obligations, covenants, conditions, requirements and terms associated with the acquisition. 7.4 ENCUMBRANCES Any assignment made pursuant to this Article 7 shall be free and clear of any encumbrances placed on the assigned Mineral Interests in favor of or by the Acquiring Party, but otherwise shall be made without warranty of title, either express or implied, except by, through and under the Acquiring Party. The assignment shall be made and accepted subject to, and assignee shall expressly assume its proportionate share of all of the obligations of the assignor pertaining to the Mineral Interest assigned, excluding overriding royalty interests, mortgages, liens, production payments or other burdens placed on the Mineral Interest by the assignor. 7.5 MERGER The provisions of this Article 7 shall not be applicable to acquisitions resulting from mergers, consolidations, or reorganizations. ARTICLE 8. DELAY RENTALS 8.1 PAYMENT OF DELAY RENTALS Subject to the terms and provisions of this JVA, the original Party who owns, or acquires an interest in leasehold shall be responsible for and shall make a diligent effort to pay each delay rental or other lease maintenance payment for the benefit of the Parties. At such time as Unocal receives an interest in the individual Ivanhoe Leases, or other leasehold acquired hereunder, Unocal shall be responsible for such payments. Neither Party shall be liable to the other Party for any loss resulting from a good-faith effort to properly pay said payments. In the event a lease for which a delay rental or other lease maintenance payment is due is located partially outside of the AMI or a portion of a lease is owned by less than all Parties, the delay rental or other lease maintenance payment shall be allocated on a surface acre basis. In the event a lease for which a delay rental or other lease maintenance payment is located all or partially within a Prospect Area, the Parties participating in the Prospect Area shall be responsible for the delay rental or other lease maintenance payment on a surface acre basis for the acreage located within the Prospect Area. 8.2 OTHER PARTY ELECTIONS The other Party shall have fourteen (14) days after receipt of an invoice of a delay rental or other lease maintenance payment or a notice of a delay rental or other lease maintenance payment coming due from the Administering Party within which to notify the Administering Party in writing of its election to pay its share of such payment. If it elects to pay its share, the other Party shall pay the Administering Party its share of such payment within thirty (30) days after the Administering Party's receipt of such election. Failure to notify shall be deemed to be an election to pay its share. In the event the other Party elects not to pay its share and the Administering Party makes the payment, the other Party shall, upon the written request of the Administering Party, assign to the Administering Party such portions of the other Party's interest in the Lease as would be maintained by such payment. 8.3 ADMINISTERING PARTY'S ELECTION NOT TO PAY Should the Administering Party elect not to pay its share of any delay rental or other lease maintenance payment, such Party shall notify the other Party at least thirty (30) days prior to the date on which such payment is due. The other Party shall have fourteen (14) days after receipt of said notice within which to notify the Administering Party of its election to pay the full amount of such payment. In the event the other Party elects to make the full payment, unless otherwise agreed, the Administering Party shall make the payment on behalf of the other Party, and the other Party shall reimburse the Administering Party and the Administering Party shall assign to the other Party such portions of the Administering Party's interest in the lease as would be maintained by such payment. FAILURE TO MAKE AN 7 <PAGE> ELECTION SHALL BE AN ELECTION TO AGREE TO NOT PAY. ARTICLE 9.

ARTICLE III. INTERESTS OF PARTIES B. INTERESTS OF PARTIES IN COSTS AND PRODUCTION: Unless changed by other provisions, all costs and liabilities incurred in operations under this agreement shall be borne and paid, and all equipment and materials acquired in operations on the Contract Area shall be owned, by the parties as their interests are set forth in Exhibit "A." In the same manner, the parties shall also own all production of Oil and Gas from the Contract Area subject, however, to the payment of royalties and other burdens on production as described hereafter. Regardless of which party has contributed any Oil and Gas Lease or Oil and Gas Interest on which royalty or other burdens may be payable and except as otherwise expressly provided in this agreement, each party shall pay or deliver, or cause to be paid or delivered, all burdens on its share of the production from the Contract Area up to, but not in excess of, The amounts agreed upon in the JVA (as hereinafter defined) and shall indemnify, defend and hold the other parties free from any liability therefor. Except as otherwise expressly provided in this agreement, if any party has contributed hereto any Lease or Interest which is burdened with any royalty, overriding royalty, production payment or other burden on production in excess of the amounts stipulated above, such party so burdened shall assume and alone bear all such excess obligations and shall indemnify, defend and hold the other parties hereto harmless from any and all claims attributable to such excess burden. However, so long as the Drilling Unit for the productive Zone(s) is identical with the Contract Area, each party shall pay or deliver, or cause to be paid or delivered, all burdens on production from the Contract Area due under the terms of the Oil and Gas Lease(s) which such party has contributed to this agreement, and shall indemnify, defend and hold the other parties free from any liability therefor.

Nothing contained in this Article III.B. shall be deemed an assignment or cross-assignment of interests covered hereby, and in the event two or more parties contribute to this agreement jointly owned Leases, the parties' undivided interests in said Leaseholds shall be deemed separate leasehold interests for the purposes of this agreement. C.

Further, if any party has contributed hereto a Lease or Interest burdened with an overriding royalty, production payment, net profits interests, or other burden payable out of production created prior to the date of this agreement, and such burden is not shown on Exhibit "A," such burden also shall be deemed a Subsequently Created Interest to the extent such burden causes the burdens on such party's Lease or Interest to exceed the amount stipulated in Article III.B. above. The party whose interest is burdened with the Subsequently Created Interest (the "Burdened Party") shall assume and alone bear, pay and discharge the Subsequently Created Interest and shall indemnify, defend and hold harmless the other parties from and against any liability therefor. Further, if the Burdened Party fails to pay, when due, its share of expenses chargeable hereunder, all provisions of Article VII.B. shall be enforceable against the Subsequently Created Interest in the same manner as they are enforceable against the working interest of the Burdened Party. If the Burdened Party is required under this agreement to assign or relinquish to any other party, or parties, all or a portion of its working interest and/or the production attributable therein, said other party, or parties, shall receive said assignment and/or production free and clear of said Subsequently Created Interest, and the Burdened Party shall indemnify, defend and hold harmless said other party, or parties, from any and all claims and demands for payment asserted by owners of the Subsequently Created Interest.

TITLE EXAMINATION: Title examination shall be made on the Drillsite of any proposed well prior to commencement of drilling operations and, if a majority in interest of the Drilling Parties so request or Operator so elects, title examination shall be made on the entire Drilling Unit, or maximum anticipated Drilling Unit, of the well. The opinion will include the ownership of the working interest, minerals, royalty, overriding royalty and production payments under the applicable Leases. Each party contributing Leases and/or Oil and Gas Interests to be included in the Drillsite or Drilling Unit, if appropriate, shall furnish to Operator all abstracts (including federal lease status reports), title opinions, title papers and curative material in its possession free of charge. All such information not in the possession of or made available to Operator by the parties, but necessary for the examination of the title, shall be obtained by Operator. Operator shall cause title to be examined by attorneys on its staff or by outside attorneys. Copies of all title opinions shall be furnished to each Drilling Party. Costs incurred by Operator in procuring abstracts, fees paid outside attorneys for title examination (including preliminary, supplemental, shut-in royally opinions and division order title opinions) and other direct charges as provided in Exhibit "C" shall be borne by the Drilling Parties in the proportion that the interest of each Drilling Party bears to the total interest of all Drilling Parties as such interests appear in Exhibit "A," Operator shall make no charge for services rendered by its staff attorneys or other personnel in the performance of the above functions. Operator shall be responsible for securing curative matter and pooling amendments or agreements required in connection with Leases or Oil and Gas Interests contributed by such patty. Operator shall be responsible for the preparation and recording of pooling designations or declarations and communitization agreements as well as the conduct of hearings before governmental agencies for the securing of spacing or pooling orders or any other orders necessary or appropriate to the conduct of operations hereunder. This shall not prevent any party from appearing on its own behalf at such hearings. Costs incurred by Operator, including fees paid to outside attorneys, which are associated with hearings before governmental agencies, and which costs are necessary and proper for the activities contemplated under this agreement, shall be direct charges to the joint account and shall not be covered by the administrative overhead charges as provided in Exhibit "C." -2- <PAGE> -2- <PAGE> A.A.P.L. FORM 610 - MODEL FORM OPERATING AGREEMENT - 1989 Operator shall make no charge for services rendered by its staff attorneys or other personnel in the performance of the above functions. No well shall be drilled on the Contract Area until after (1) the title to the Drillsite or Drilling Unit, if appropriate, has been examined as above provided, and (2) the title has been approved by the examining attorney or title has been accepted by all of the Drilling Parties in such well. B. LOSS OR FAILURE OF TITLE: 3. Losses: All losses of Leases or Interests committed to this agreement, shall be joint losses and shall be borne by all parties in proportion to their interests shown on Exhibit "A."

There shall be no readjustment of interests in the remaining portion of the Contract Area on account of any joint loss. -3- <PAGE> A.A.P.L. FORM 610 - MODEL FORM OPERATING AGREEMENT - 1989 ARTICLE V. OPERATOR A. Designation and Responsibilities of Operator: Union Oil Company of California shall be the Operator of the Contract Area, and shall conduct and direct and have full control of all operations on the Contract Area as permitted and required by, and within the limits of this agreement. In its performance of services hereunder for the Non-Operators, Operator shall be an independent contractor not subject to the control or direction of the Non-Operators except as to the type of operation to be undertaken in accordance with the election procedures contained in this agreement. Operator shall not be deemed, or hold itself out as, the agent of the Non-Operators with authority to bind them to any obligation or liability assumed or incurred by Operator as to any third party. Operator shall conduct its activities under this agreement as a reasonable prudent operator, in a good and workmanlike manner, with due diligence and dispatch, in accordance with good oilfield practice, and in compliance with applicable law and regulation, but in no event shall it have any liability as Operator to the other parties for losses sustained or liabilities incurred except such as may result from gross negligence or willful misconduct. B. Resignation or Removal of Operator and Selection of Successor: 1. Resignation or Removal of Operator: Operator may resign at any time by giving written notice thereof to Non-Operators. If Operator terminates its legal existence, no longer owns an interest hereunder in the Contract Area, or is no longer capable of serving as Operator, Operator shall be deemed to have resigned without any action by Non-Operators, except the selection of a successor. Operator may be removed only for good cause by the affirmative vote of Non-Operators owning a majority interest based on ownership as shown on Exhibit "A" remaining after excluding the voting interest of Operator; such vote shall not be deemed effective until a written notice has been delivered to the Operator by a Non-Operator detailing the alleged default and Operator has failed to cure the default within thirty (30) days from its receipt of the notice or, if the default concerns an operation then being conducted, within forty-eight (48) hours of its receipt of the notice. For purposes hereof, "good cause" shall mean not only gross negligence or willful misconduct but also the material breach of or inability to meet the standards of operation contained in Article V.A. or material failure or inability to perform its obligations under this agreement. Subject to Article VII.D.l., such resignation or removal shall not become effective until 7:00 o'clock A.M. on the first day of the calendar month following the expiration of ninety (90) days after the giving of notice of resignation by Operator or action by the Non-Operators to remove Operator, unless a successor Operator has been selected and assumes the duties of Operator at an earlier date. Operator, after effective date of resignation or removal, shall be bound by the terms hereof as a Non-Operator. A change of a corporate name or structure of Operator or of Operator's interest to any single subsidiary, parent or successor corporation shall not be the basis for removal of Operator. 2. Selection of Successor Operator: Upon the resignation or removal of Operator under any provision of this agreement, a successor Operator shall be selected by the parties. The successor Operator shall be selected from the parties owning an interest in the Contract Area at the time such successor Operator is selected. The successor Operator shall be selected by the affirmative vote of ONE (1) or more parties owning a majority interest based on ownership as shown on Exhibit "A"; provided, however, if an Operator which has been removed or is deemed to have resigned fails to vote or votes only to succeed itself, the successor Operator shall be selected by the affirmative vote of the party or parties owning a majority interest based on ownership as shown on Exhibit "A" remaining after excluding the voting interest of the Operator that was removed or resigned. The former Operator shall promptly deliver to the successor Operator all records and data relating to the operations conducted by the former Operator to the extent such records and data are not already in the possession of the successor operator. Any cost of obtaining or copying the former Operator's records and data shall be charged to the joint account. 3. Effect of Bankruptcy: If Operator becomes insolvent, bankrupt or is placed in receivership, it shall be deemed to have resigned without any action by Non-Operators, except the selection of a successor. If a petition for relief under the federal bankruptcy laws is filed by or against Operator, and the removal of Operator is prevented by the federal bankruptcy court, all Non-Operators and Operator shall comprise an interim operating committee to serve until Operator has elected to reject or assume this agreement pursuant to the Bankruptcy Code, and an election to reject this agreement by Operator as a debtor in possession, or by a trustee in bankruptcy, shall be deemed a resignation as Operator without any action by Non-Operators, except the selection of a successor. During the period of time the operating committee controls operations, all actions shall require the approval of two (2) or more parties owning a majority interest based on ownership as shown on Exhibit "A." In the event there are only two (2) parties to this agreement, during the period of time the operating committee controls operations, a third party acceptable to Operator, Non-Operator and the federal bankruptcy court shall be selected as a member of the operating committee, and all actions shall require the approval of two (2) members of the operating committee without regard for their interest in the Contract Area based on Exhibit "A." C. Employees and Contractors: The number of employees or contractors used by Operator in conducting operations hereunder, their selection, and the hours of labor and the compensation for services performed shall be determined by Operator, and all such employees of contractors shall be the employees or contractors of Operator. D. Rights and Duties of Operator: 1. Competitive Rates and Use of Affiliates: All wells drilled on the Contract Area shall be drilled on a competitive contract basis at the usual rates prevailing in the area. If it so desires, Operator may employ its own tools and equipment in the drilling of wells, but its charges therefor shall not exceed the prevailing rates in the area and the rate of such charge; shall be agreed upon by the parties in writing before drilling operations are commenced, and such work shall be performed by Operator under the same terms and conditions as are customary and usual in the area in contracts of independent contractors who are doing work of a similar nature. All work performed or materials supplied by affiliates or related parties of Operator shall be performed or supplied at competitive rates, pursuant to written agreement, and in accordance with customs and standards prevailing in the industry. 2. Discharge of Joint Account Obligations: Except as herein otherwise specifically provided, Operator shall promptly pay and discharge expenses incurred in the development and operation of the Contract Area pursuant to this agreement and shall charge each of the parties hereto with their respective proportionate shares upon the expense basis provided in Exhibit "C." Operator shall keep an accurate record of the joint account, hereunder, showing expenses incurred and charges and credits made and received. 3. Protection from Liens: Operator shall pay, or cause to be paid, as and when they become due and payable, all accounts of contractors and suppliers and wages and salaries for services rendered or performed, and for materials supplied on, to or in respect of the Contract Area or any operations for the joint account thereof, and shall keep the Contract Area free from -4- <PAGE> A.A.P.L. FORM 610 - MODEL FORM OPERATING AGREEMENT - 1989 liens and encumbrances resulting therefrom except for those resulting from a bona fide dispute as to services rendered or materials supplied. 4. Custody of Funds: Operator shall hold for the account of the Non-Operators any funds of the Non-Operators advanced or paid to the Operator, either for the conduct of operations hereunder or as a result of the sale of production from the Contract Area, and such funds shall remain the funds of the Non-Operators on whose account they are advanced or paid until used for their intended purpose or otherwise delivered to the Operators or applied toward the payment of debts as provided in Article VII.B. Nothing in this paragraph shall be construed to establish a fiduciary relationship between Operator and Non-Operators for any purpose other than to account for Non-Operator funds as herein specifically provided. Nothing in this paragraph shall require the maintenance by Operator of separate accounts for the funds of Non-Operators unless the parties otherwise specifically agree. 5. Access to Contract Area and Records: Operator shall, except as otherwise provided herein, permit each Non-Operator or its duly authorized representative, at the Non-Operator's sole risk and cost, full and free access at all reasonable times to all operations of every kind and character being conducted for the joint account on the Contract Area and to the records of operations conducted thereon or production therefrom, including Operator's books and records relating thereto. Such access rights shall not be exercised in a manner interfering with Operator's conduct of an operation hereunder and shall not obligate Operator to furnish any geologic or geophysical data of an interpretive nature unless the cost of preparation of such interpretive data was charged to the joint account. Operator will furnish to each Non-Operator upon request copies of any and all reports and information obtained by Operator in connection with production and related items, including, without limitation, meter and chart reports, production purchaser statements, run tickets and monthly gauge reports, but excluding purchase contracts and pricing information to the extent not applicable to the production of the Non-Operator seeking the information. Any audit of Operator's records relating to amounts expended and the appropriateness of such expenditures shall be conducted in accordance with the audit protocol specified in Exhibit "C." 6. Filing and Furnishing Governmental Reports: Operator will file, and upon written request promptly furnish copies to each requesting Non-Operator not in default of its payment obligations, all operational notices, reports or applications required to be filed by local, State, Federal or Indian agencies or authorities having jurisdiction over operations hereunder. Each Non-Operator shall provide to Operator on a timely basis all information necessary to Operator to make such filings. 7. Drilling and Testing Operations: The following provisions shall apply to each well drilled hereunder, including but not limited to the Initial Well: (a) Operator will promptly advise Non-Operators of the date on which the well is spudded, or the date on which drilling operations are commenced. (b) Operator will send to Non-Operators such reports, test results and notices regarding the progress of operations on the well as the Non-Operators shall reasonably request, including, but not limited to, daily drilling reports, completion reports, and well logs. (c) Operator shall adequately test all Zones encountered which may reasonably be expected to be capable of producing Oil and Gas in paying quantities as a result of examination of the electric log or any other logs or cores or tests conducted hereunder. 8. Cost Estimates: Operator shall furnish estimates of current and cumulative costs incurred for the joint account at reasonable intervals during the conduct of any operation pursuant to this agreement. Operator shall not be held liable for errors in such estimates so long as the estimates are made in good faith. 9. Insurance: At all times while operations are conducted hereunder, Operator shall comply with the workers compensation law of the state where the operations are being conducted; provided, however, that Operator may be a self-insurer for liability under said compensation laws in which event the only charge that shall be made to the joint account shall be as provided in Exhibit "C." Operator shall also carry or provide insurance for the benefit of the joint account of the parties as outlined in Exhibit "D" attached hereto and made a part hereof. Operator shall require all contractors engaged in work on or for the Contract Area to comply with the workers compensation law of the state where the operations are being conducted maintain such other insurance as Operator may require. In the event automobile liability insurance is specified in said Exhibit "D," or subsequently receives the approval parties, no direct charge shall be made by Operator for premiums paid for such insurance for Operator's automotive equipment. ARTICLE VI. DRILLING AND DEVELOPMENT B. Operations: I. Proposed Operations: If any party hereto should desire to drill any well on the Contract Area, or if any party should desire to Rework, Sidetrack, Deepen, Recomplete or Plug Back a dry hole or a well no longer capable of producing in paying quantities in which such party has not otherwise relinquished its interest in the proposed objective Zone under this agreement, the party desiring to drill, Rework, Sidetrack, Deepen, Recomplete or Plug Back such a well shall give written notice of the proposed operation to the parties who have not otherwise relinquished their interest in such objective Zone. -5- <PAGE> A.A.P.L. FORM 610 - MODEL FORM OPERATING AGREEMENT - 1989 under this agreement and to all other parties in the case of a proposal for Sidetracking or Deepening, specifying the work to be performed, the location, proposed depth, objective Zone and the estimated cost of the operation. The parties to whom such a notice is delivered shall have thirty (30) days after receipt of the notice within which to notify the party proposing to do the work whether they elect to participate in the cost of the proposed operation. If a drilling rig is on location, notice of a proposal to Rework, Sidetrack, Recomplete, Plug Back or Deepen may be given by telephone and the response period shall be limited to forty-eight (48) hours, exclusive of Saturday, Sunday and legal holidays. Failure of a party to whom such notice is delivered to reply within the period above fixed shall constitute an election by that party not to participate in the cost of the proposed operation. Any proposal by a party to conduct an operation conflicting with the operation initially proposed shall be delivered to all parties within the time and in the manner provided in Article VI.B.6. If all parties to whom such notice is delivered elect to participate in such a proposed operation, the parties shall be contractually committed to participate therein provided such operations are commenced within the time period hereafter set forth, and Operator shall, no later than ninety (90) days after expiration of the notice period of thirty (30) days (or as promptly as practicable after the expiration of the forty-eight (48) hour period when a drilling rig is on location, as the case may be), actually commence the proposed operation and thereafter complete it with due diligence at the risk and expense of the parties participating therein; provided, however, said commencement date may be extended upon written notice of same by Operator to the other parties, for a period of up to thirty (30) additional days if, in the sole opinion of Operator, such additional time is reasonably necessary to obtain permits from governmental authorities, surface rights (including rights-of-way) or appropriate drilling equipment, or to complete title examination or curative matter required for title approval or acceptance. If the actual operation has not been commenced within the time provided (including any extension thereof as specifically permitted herein or in the force majeure provisions of Article XI) and if any party hereto still desires to conduct said operation, written notice proposing same must be resubmitted to the other parties in accordance herewith as if no prior proposal had been made. Those parties that did not participate in the drilling of a well for which a proposal to Deepen or Sidetrack is made hereunder shall, if such parties desire to participate in the proposed Deepening or Sidetracking operation, reimburse the Drilling Parties in accordance with Article VI.B.4. in the event of a Deepening operation and in accordance with Article VI.B.5. in the event of a Sidetracking operation. 2. Operations by Less Than All Parties: (a) Determination of Participation. If any party to whom such notice is delivered as provided in Article VI.B.1. or VI.C.1. (Option No. 2) elects not to participate in the proposed operation, then, in order to be entitled to the benefits of this Article, the party or parties giving the notice and such other parties as shall elect to participate in the operation shall, no later than ninety (90) days after the expiration of the notice period of thirty (30) days (or as promptly as practicable after the expiration of the forty-eight (48) hour period when a drilling rig is on location, as the case may be) actually commence the proposed operation and complete it with due diligence. Operator shall perform all work for the account of the Consenting Parties; provided, however, if no drilling rig or other equipment is on location, and if Operator is a Non-Consenting Party, the Consenting Parties shall either: (i) request Operator to perform the work required by such proposed operation for the account of the Consenting Parties, or (ii) designate one of the Consenting Parties as Operator to perform such work. The rights and duties granted to and imposed upon the Operator under this agreement are granted to and imposed upon the party designated as Operator for an operation in which the original Operator is a Non-Consenting Party. Consenting Parties, when conducting operations on the Contract Area pursuant to this Article VI.B.2., shall comply with all terms and conditions of this agreement. If less than all parties approve any proposed operation, the proposing party, immediately after the expiration of the applicable notice period, shall advise all Parties of the total interest of the parties approving such operation and its recommendation as to whether the Consenting Parties should proceed with the operation as proposed. Each Consenting Party, within forty-eight (48) hours a after receipt of such notice, shall advise the proposing party of its desire to (i) limit participation to such party's interest as shown on Exhibit "A" or (ii) carry only its proportionate part (determined by dividing such party's interest in the Contract Area by the interests of all Consenting Parties in the Contract Area) of Non-Consenting Parties' interests, or (iii) carry its proportionate part (determined as provided in (ii)) of Non-Consenting Parties' interests together with all or a portion of its proportionate part of any Non-Consenting Parties' interests that any Consenting Party did not elect to take. Any interest of Non-Consenting Parties that is not carried by a Consenting Party shall be deemed to be carried by the party proposing the operation if such party does not withdraw its proposal. Failure to advise the proposing party within the time required shall be deemed an election under (i). In the event a drilling rig is on location, notice may be given by telephone, and the time permitted for such a response shall not exceed a total of forty-eight (48) hours. The proposing party, at its election, may withdraw such proposal if there is less than 100% participation and shall notify all parties of such decision within ten (10) days, or within twenty-four (24) hours if a drilling rig is on location, following expiration of the applicable response period. If 100% subscription to the proposed operation is obtained, the proposing party shall promptly notify the Consenting Parties of their proportionate interests in the operation and the party serving as Operator shall commence such operation within the period provided in Article VI.B.l., subject to the same extension right as provided therein. (b) Relinquishment of Interest for Non-Participation. The entire cost and risk of conducting such operations shall be borne by the Consenting Parties in the proportions they have elected to bear same under the terms of the preceding paragraph. Consenting Parties shall keep the leasehold estates involved in such operations free and clear of all liens and encumbrances of every kind created by or arising from the operations of the Consenting Parties. If such an operation results in a dry hole, then subject to Articles VI.B.6. and VI.E.3., the Consenting Parties shall plug and abandon the well and restore the surface location at their sole cost, risk and expense; provided, however, that those Non-Consenting Parties that participated in the drilling, Deepening or Sidetracking of the well shall remain liable for, and shall pay, their proportionate shares of the cost of plugging and abandoning the well and restoring the surface location insofar only as those costs were not increased by the subsequent operations of the Consenting Parties. If any well drilled, Reworked, Sidetracked, Deepened, Recompleted or Plugged Back under the provisions of this Article results in a well capable of producing Oil and/or Gas in paying quantities, the Consenting Parties shall Complete and equip the well to produce at their sole cost and risk, and the well shall then be turned over to Operator (if the Operator did not conduct the operation) and shall be operated by it at the expense and for the account of the Consenting Parties. Upon commencement of operations for the drilling, Reworking, Sidetracking, Recompleting, Deepening or Plugging Back of any such well by Consenting Parties in accordance with the provisions of this Article, each Non-Consenting Party shall be deemed to have relinquished to Consenting Parties, and the Consenting Parties shall own and be entitled to receive, in proportion to their respective interests, all of such Non-Consenting Party's interest in the well and share of production therefrom or, in the case of a Reworking, Sidetracking, -6- <PAGE> A.A.P.L. FORM 610 - MODEL FORM OPERATING AGREEMENT - 1989 Deepening, Recompleting or Plugging Back, or a Completion pursuant to Article VI.C.1. Option No. 2, all of such Non-Consenting Party's interest in the production obtained from the operation in which the Non-Consenting Party did not elect to participate. Such relinquishment shall be effective until the proceeds of the sale of such share, calculated at the well, or market value thereof if such share is not sold (after deducting applicable ad valorem, production, severance, and excise taxes, royalty, overriding royalty and other interests not excepted by Article III.C. payable out of or measured by the production from such well accruing with respect to such interest until it reverts), shall equal the total of the following: (i) 100% of each such Non-Consenting Party's share of the cost of any newly acquired surface equipment beyond the wellhead connections (including but not limited to stock tanks, separators, treaters, pumping equipment and piping), plus 100% of each such Non-Consenting Party's share of the cost of operation of the well commencing with first production and continuing until each such Non-Consenting Party's relinquished interest shall revert to it under other provisions of this Article, it being agreed that each Non-Consenting Party's share of such costs and equipment will be that interest which would have been chargeable to such Non-Consenting Party had it participated in the well from the beginning of the operations; and (ii) 400% of (a) that portion of the costs and expenses of drilling, Reworking, Sidetracking, Deepening, Plugging Back, testing, Completing, and Recompleting, after deducting any cash contributions received under Article VIII.C., and of (b) that portion of the cost of newly acquired equipment in the well (to and including the wellhead connections), which would have been chargeable to such Non-Consenting Party if it had participated therein. Notwithstanding anything to the contrary in this Article VI.B., if the well does not reach the deepest objective Zone described in the notice proposing the well for reasons other than the encountering of granite or practically impenetrable substance or other condition in the hole rendering further operations impracticable, Operator shall give notice thereof to each Non-Consenting Party who submitted or voted for an alternative proposal under Article VI.B.6. to drill the well to a shallower Zone than the deepest objective Zone proposed in the notice under which the well was drilled, and each such Non-Consenting Party shall have the option to participate in the initial proposed Completion of the well by paying its share of the cost of drilling the well to its actual depth, calculated in the manner provided in Article VI.B.4. (a). If any such Non-Consenting Party does not elect to participate in the first Completion proposed for such well, the relinquishment provisions of this Article VI.B.2. (b) shall apply to such party's interest. (c) Reworking, Recompleting or Plugging Back. An election not to participate in the drilling, Sidetracking or Deepening of a well shall be deemed an election not to participate in any Reworking, Recompletion or Plugging Back operation proposed in such a well, or portion thereof, to which the initial non-consent election applied that is conducted at any time prior to full recovery by the Consenting Parties of Non-Consenting Party's recoupment amount. Similarly, an election not to participate in the Completing or Recompleting of a well shall be deemed an election not to participate in any Reworking operation proposed in such a well, or portion thereof, to which the initial non-consent election applied that is conducted at any time prior to full recovery by the Consenting Parties of the Non-Consenting Party's recoupment amount. Any such Reworking, Recompleting or Plugging Back operation conducted during the recoupment period shall be deemed part of the cost of operation of said well and there shall be added to the sums to be recouped by the Consenting Parties 200% of that portion of the costs of the Reworking, Recompleting or Plugging Back operation which would have been chargeable to such Non-Consenting Party had it participated therein. If such a Reworking, Recompleting or Plugging Back operation is proposed during such recoupment period, the provisions of this Article VI.B. shall be applicable as between said Consenting Parties in said well. (d) Recoupment Matters. During the period of time Consenting Parties are entitled to receive Non-Consenting Party's share of production, or the proceeds therefrom, Consenting Parties shall be responsible for the payment of all ad valorem, production, severance, excise, gathering and other taxes, and all royalty, overriding royalty and other burdens applicable to Non-Consenting Party's share of production not excepted by Article III.C. In the case of any Reworking, Sidetracking, Plugging Back, Recompleting or Deepening operation, the Consenting Parties shall be permitted to use, free of cost, all casing, tubing and other equipment in the well, but the ownership of all such equipment shall remain unchanged; and upon abandonment of a well after such Reworking, Sidetracking, Plugging Back, Recompleting or Deepening, the Consenting Parties shall account for all such equipment to the owners thereof, with each party receiving its proportionate part in kind or in value, less cost of salvage. Within ninety (90) days after the completion of any operation under this Article, the party conducting the operations for the Consenting Parties shall furnish each Non-Consenting Party with an inventory of the equipment in and connected to well, and an itemized statement of the cost of drilling, Sidetracking, Deepening, Plugging Back, testing, Completing, Recompleting, and equipping the well for production; or, at its option, the operating party, in lieu of an itemized statement of such costs of operation, may submit a detailed statement of monthly billings. Each month thereafter, during the time the Consenting Parties are being reimbursed as provided above, the party conducting the operations for the Consenting Parties shall furnish the Non-Consenting Parties with an itemized statement of all costs and liabilities incurred in the operation of the well, together with a statement of the quantity of Oil and Gas produced from it and the amount of proceeds realized from the sale of the well's working interest production during the preceding month. In determining the quantity of Oil and Gas produced during any month, Consenting Parties shall use industry accepted methods such as but not limited to metering or periodic well tests. Any amount realized from the sale or other disposition of equipment newly acquired in connection with any such operation which would have been owned by a Non-Consenting Party had it participated therein shall be credited against the total unreturned costs of the work done and of the equipment purchased in determining when the interest of such Non-Consenting Party shall revert to it as above provided; and if there is a credit balance, it shall be paid to such Non-Consenting Party. If and when the Consenting Parties recover from a Non-Consenting Party's relinquished interest the amounts provided for above, the relinquished interests of such Non-Consenting Party shall automatically revert to it as of 7:OO a.m. on the day following the day on which such recoupment occurs, and, from and after such reversion, such Non-Consenting Party shall own the same interest in such well, the material and equipment in or pertaining thereto, and the production therefrom as such Non-Consenting Party would have been entitled to had it participated in the drilling, Sidetracking, Reworking, Deepening, Recompleting or Plugging Back of said well. Thereafter, such Non-Consenting Party shall be charged with and shall pay its proportionate part of the further costs of the operation of said well in accordance with the terms of this agreement and Exhibit "C" attached hereto. 3. Stand-By Costs: When a well which has been drilled or Deepened has reached its authorized depth and all tests have been completed and the results thereof furnished to the parties, or when operations on the well have been otherwise terminated pursuant to Article VI.P., stand-by costs incurred, pending response to a party's notice proposing a Reworking, -7- <PAGE> A.A.P.L. FORM 610 - MODEL FORM OPERATING AGREEMENT - 1989 Sidetracking, Deepening, Recompleting, Plugging Back or Completing operation in such a well (including the period required under Article VI.B.6. to resolve competing proposals) shall be charged and borne as part of the drilling or Deepening operation just completed. Stand-by costs subsequent to all parties responding, or expiration of the response time permitted, whichever first occurs, and prior to agreement as to the participating interests of all Consenting Parties pursuant to the terms of the second grammatical paragraph of Article VI.B.2. (a), shall be charged to and borne as part of the proposed operation, but if the proposal is subsequently withdrawn because of insufficient participation, such stand-by costs shall be allocated between the Consenting Parties in the proportion each Consenting Party's interest as shown on Exhibit "A" bears to the total interest as shown on Exhibit "A" of all Consenting Parties. In the event that notice for a Sidetracking operation is given while the drilling rig to be utilized is on location, any party may request and receive up to five (5) additional days after expiration of the forty-eight hour response period specified in Article VI.B.l. within which to respond by paying for all stand-by costs and other costs incurred during such extended response period; Operator may require such party to pay the estimated stand-by time in advance as a condition to extending the response period. If more than one party elects to take, such additional time to respond to the notice, standby costs shall be allocated between the parties taking additional time to respond on a day-to-day basis in the proportion each electing party's interest as shown on Exhibit "A" bears to the total interest as shown on Exhibit "A" of all the electing parties. 4. Deepening: If less than all parties elect to participate in a drilling, Sidetracking, or Deepening operation proposed pursuant to Article VI.B.1., the interest relinquished by the Non-Consenting Parties to the Consenting Parties under Article VI.B.2. shall relate only and be limited to the lesser of (i) the total depth actually drilled or (ii) the objective depth or Zone of which the parties were given notice under Article VI.B.1. ("Initial Objective"). Such well shall not be Deepened beyond the Initial Objective without first complying with this Article to afford the Non-Consenting Parties the opportunity to participate in the Deepening operation. In the event any Consenting Party desires to drill or Deepen a Non-Consent Well to a depth below the Initial Objective, such party shall give notice thereof, complying with the requirements of Article VI.B.l., to all parties (including Non-Consenting Parties). Thereupon, Articles VI.B.1. and 2. shall apply and all parties receiving such notice shall have the right to participate or not participate in the Deepening of such well pursuant to said Articles VI.B.1. and 2. If a Deepening operation is approved pursuant to such provisions, and if any Non-Consenting Party elects to participate in the Deepening operation, such Non-Consenting party shall pay or make reimbursement (as the case may be) of the following costs and expenses. (a) If the proposal to Deepen is made prior to the Completion of such well as a well capable of producing in paying quantities, such Non-Consenting Party shall pay (or reimburse Consenting Parties for, as the case may be) that share of costs and expenses incurred in connection with the drilling of said well from the surface to the Initial Objective which Non-Consenting Party would have paid had such Non-Consenting Party agreed to participate therein, plus the Non-Consenting Party's share of the cost of Deepening and of participating in any further operations on the well in accordance with the other provisions of this Agreement; provided, however, all costs for testing and Completion or attempted Completion of the well incurred by Consenting Parties prior to the point of actual operations to Deepen beyond the Initial Objective shall be for the sole account of Consenting Parties. (b) If the proposal is made for a Non-Consent Well that has been previously Completed as a well capable of producing in paying quantities, but is no longer capable of producing in paying quantities, such Non-Consenting Party shall pay (or reimburse Consenting Parties for, as the case may be) its proportionate share of all costs of drilling, Completing, and equipping said well from the surface to the Initial Objective, calculated in the manner provided in paragraph (a) above, less those costs recouped by the Consenting Parties from the sale of production from the well. The Non-Consenting Party shall also pay its proportionate share of all costs of re-entering said well. The Non-Consenting Parties' proportionate part (based on the percentage of such well Non-Consenting Party would have owned had it previously participated in such Non-Consent Well) of the costs of salvable materials and equipment remaining in the hole and salvable surface equipment used in connection with such well shall be determined in accordance with Exhibit "C." If the Consenting Parties have recouped the cost of drilling, Completing, and equipping the well at the time such Deepening operation is conducted, then a Non-Consenting Party may participate in the Deepening of the well with no payment for costs incurred prior to re-entering the well for Deepening. The foregoing shall not imply a right of any Consenting Party to propose any Deepening for a Non-Consent Well prior to the drilling of such well to its Initial Objective without the consent of the other Consenting Parties as provided in Article VI.F. 5. Sidetracking: Any party having the right to participate in a proposed Sidetracking operation that does not own an interest in the affected wellbore at the time of the notice shall, upon electing to participate, tender to the wellbore owners its proportionate share (equal to its interest in the Sidetracking operation) of the value of that portion of the existing wellbore to be utilized as follows: (a) If the proposal is for Sidetracking an existing dry hole, reimbursement shall be on the basis of the actual costs incurred in the initial drilling of the well down to the depth at which the Sidetracking operation is initiated. (b) If the proposal is for Sidetracking a well which has previously produced, reimbursement shall be on the basis of such party's proportionate share of drilling and equipping costs incurred in the initial drilling of the well down to the depth at which the Sidetracking operation is conducted, calculated in the manner described in Article VI.B.4(b) above. Such party's proportionate share of the cost of the well's salvable materials and equipment down to the depth at which the Sidetracking operation is initiated shall be determined in accordance with the provisions of Exhibit "C." 6. Order of Preference of Operations. Except as otherwise specifically provided in this agreement, if any party desires to propose the conduct of an operation that conflicts with a proposal that has been made by a party under this Article VI, such party shall have fifteen (15) days from delivery of the initial proposal, in the case of a proposal to drill a well or to perform an operation on a well where no drilling rig is on location, or twenty-four (24) hours, from delivery of the initial proposal, if a drilling rig is on location for the well on which such operation is to be conducted, to deliver to all parties entitled to participate in the proposed operation such party's alternative proposal, such alternate proposal to contain the same information required to be included in the initial proposal. Each party receiving such proposals shall elect by delivery of notice to Operator within five (5) days after expiration of the proposal period, or within twenty-four (24) hours if a drilling rig is on location for the well that is the subject of the proposals, to participate in one of the competing proposals. Any party not electing within the time required shall be deemed not to have voted. The proposal receiving the vote of parties owning the largest aggregate percentage interest of the parties voting shall have priority over all other competing proposals; in the case of a tie vote, the -8- <PAGE> A.A.P.L. FORM 610 - MODEL FORM OPERATING AGREEMENT - 1989 initial proposal shall prevail. Operator shall deliver notice of such result to all parties entitled to participate in the operation within five (5) days after expiration of the election period (or within twenty-four (24) hours, exclusive of Saturday, Sunday and legal holidays, if a drilling rig is on location). Each party shall then have two (2) days (or twenty-four (24) hours if a rig is on location) from receipt of such notice to elect by delivery of notice to Operator to participate in such operation or to relinquish interest in the affected well pursuant to the provisions of Article VI.B.2.; failure by a party to deliver notice within such period shall be deemed an election not to participate in the prevailing proposal. 7. Conformity to Spacing Pattern. Notwithstanding the provisions of this Article VI.B.2., it is agreed that no wells shall be proposed to be drilled to or Completed in or produced from a Zone from which a well located elsewhere on the Contract Area is producing, unless such well conforms to the then-existing well spacing pattern for such Zone. 8. Paving Wells. No party shall conduct any Reworking, Deepening, Plugging Back, Completion, Recompletion, or Sidetracking operation under this agreement with respect to any well then capable of producing in paying quantities except with the consent of all parties that have not relinquished interests in the well at the time of such operation. C. COMPLETION OF WELLS; REWORKING AND PLUGGING BACK: 1. Completion: Without the consent of all parties, no well shall be drilled, Deepened or Sidetracked, except any well drilled, Deepened or Sidetracked pursuant to the provisions of Article VI.B.2. of this agreement. Consent to the drilling, Deepening or Sidetracking shall include: [X] Option No 2. All necessary expenditures for drilling, Deepening or Sidetracking and testing of the well. When such well has reached its authorized depth, and all logs, cores and other tests have been completed, and the results thereof furnished to the parties, Operator shall give immediate notice to the Non-Operators having the right to participate in a Completion attempt whether or not Operator recommends attempting to Complete the well, together with Operator's AFE for Completion costs if not previously provided. The parties receiving such notice shall have forty-eight (48) hours in which to elect by delivery of notice to Operator to participate in a recommended Completion attempt or to make a Completion proposal with an accompanying AFE. Operator shall deliver any such Completion proposal, or any Completion proposal conflicting with Operator's proposal, to the other parties entitled to participate in such Completion in accordance with the procedures specified in Article VI.B.6. Election to participate in a Completion attempt shall include consent, to all necessary expenditures for the Completing and equipping of such well, including necessary tankage and/or surface facilities but excluding any stimulation operation not contained on the Completion AFE. Failure of any party receiving such notice to reply within the period above fixed shall constitute an election by that party NOT to participate in the cost of the Completion attempt; provided, that Article VI.B.6. shall control in the case of conflicting Completion proposals. If one or more, but less than all of the parties, elect to attempt a Completion, the provision of Article VI.B.2. hereof (the phrase "Reworking, Sidetracking, Deepening, Recompleting or Plugging Back" as contained in Article VI.B.2. shall be deemed to include "Completing") shall apply to the operations thereafter conducted by less than all parties; provided, however, that Article VI.B.2. shall apply separately to each separate Completion or Recompletion attempt undertaken hereunder, and an election to become a Non-Consenting Party as to one Completion or Recompletion attempt shall not prevent a party from becoming a Consenting Party in subsequent Completion or Recompletion attempts regardless whether the Consenting Parties as to earlier Completions or Recompletion have recouped their costs pursuant to Article VI.B.2.; provided further, that any recoupment of costs by a Consenting Party shall be made solely from the production attributable to the Zone in which the Completion attempt is made. Election by a previous Non-Consenting party to participate in a subsequent Completion or Recompletion attempt shall require such party to pay its proportionate share of the cost of salvable materials and equipment installed in the well pursuant to the previous Completion or Recompletion attempt, insofar and only insofar as such materials and equipment benefit the Zone in which such party participates in a Completion attempt. 2. Rework, Recomplete or Plug Back: No well shall be Reworked, Recompleted or Plugged Back except a well Reworked, Recompleted, or Plugged Back pursuant to the provisions of article VI.B.2. of this agreement. Consent to the Reworking, Recompleting or Plugging Back of a well shall include all necessary expenditures in conducting such operations and Completing and equipping of said well, including necessary tankage and/or surface facilities. D. OTHER OPERATIONS: Operator shall not undertake any single project reasonably estimated to require an expenditure in excess of Fifty Thousand Dollars ($50,000.00) except in connection with the drilling, Sidetracking, Reworking, Deepening, Completing, Recompleting or Plugging Back of a well that has been previously authorized by or pursuant to this agreement; provided, however, that, in case of explosion, fire, flood or other sudden emergency, whether of the same or different nature, Operator may take such steps and incur such expenses as in its opinion are required to deal with the emergency to safeguard life and property but Operator, as promptly as possible, shall report the emergency to the other parties. If Operator prepares an AFE for its own use, Operator shall furnish any Non-Operator so requesting an information copy thereof for any single project costing in excess of Twenty-five Thousand Dollars ($25,000.00). Any party who has not relinquished its interest in a well shall have the right to propose that Operator perform repair work or undertake the installation of artificial lift equipment or ancillary production facilities such as salt water disposal wells or to conduct additional work with respect to a well drilled hereunder or other similar project (but not including the installation of gathering lines or other transportation or marketing facilities, the installation of which shall be governed by separate agreement between the parties) reasonably estimated to require an expenditure in excess of the amount first set forth above in this Article VI.D. (except in connection with an operation required to be proposed under Articles VI.B.1. or VI.C.l. Option No. 2, which shall be governed exclusively be those Articles). Operator shall deliver such proposal to all parties entitled to participate therein. If within thirty (30) days thereof Operator secures the written consent of any party or parties owning at least 51% of the interests of the parties entitled to participate in such operation, each party having the right to participate in such project shall be bound by the terms of such proposal and shall be obligated to pay its proportionate share of the costs of the proposed project as if it had consented to such project pursuant to the terms of the proposal. E. ABANDONMENT OF WELLS: 1. Abandonment of Dry Holes: Except for any well drilled or Deepened pursuant to Article VI.B.2., any well which has been drilled or Deepened under the terms of this agreement and is proposed to be completed as a dry hole shall not be -9- <PAGE> A.A.P.L. FORM 610 - MODEL FORM OPERATING AGREEMENT - 1989 plugged and abandoned without the consent of all parties. Should Operator, after diligent effort, be unable to contact any party, or should any party fail to reply within forty-eight (48) hours after delivery of notice of the proposal to plug and abandon such well, such party shall be deemed to have consented to the proposed abandonment. All such wells shall be plugged and abandoned in accordance with applicable regulations and at the cost, risk and expense of the parties who participated in the cost of drilling or Deepening such well. Any party who objects to plugging and abandoning such well by notice delivered to Operator within forty-eight (48) hours after delivery of notice of the proposed plugging shall take over the well as of the end of such forty-eight (48) hour notice period and conduct further operations in search of Oil and/or Gas subject to the provisions of Article VI.B.; failure of such party to provide proof reasonably satisfactory to Operator of its financial capability to conduct such operations or to take over the well within such period or thereafter to conduct operations on such well or plug and abandon such well shall entitle Operator to retain or take possession of the well and plug and abandon the well. The Party taking over the well shall indemnify Operator (if Operator is an abandoning party) and the other abandoning parties against liability for any further operations conducted on such well except for the costs of plugging and abandoning the well and restoring the surface, for which the abandoning parties shall remain proportionately liable. 2. Abandonment of Wells That Have Produced: Except for any well in which a Non-Consent operation has been conducted hereunder for which the Consenting Parties have not been fully reimbursed as herein provided, any well which has been completed as production, whether or not such well has produced, shall not be plugged and abandoned without the consent of all parties. If all parties consent to such abandonment, the well shall be plugged and abandoned in accordance with applicable regulations and at the cost, risk and expense of all the parties hereto. Failure of a party to reply within sixty (60) days of delivery of notice of proposed abandonment shall be deemed an election to consent to the proposal. If, within sixty (60) days after delivery of notice of the proposed abandonment of any well, all parties do not agree to the abandonment of such well, those wishing to continue its operation from the Zone then open to production shall be obligated to take over the well as of the expiration of the applicable notice period and shall indemnify Operator (if Operator is an abandoning party) and the other abandoning parties against liability for any further operations on the well conducted by such parties. Failure of such party or parties to provide proof reasonably satisfactory to Operator of their financial capability to conduct such operations or to take over the well within the required period or thereafter to conduct operations on such well shall entitle operator to retain or take possession of such well and plug and/abandon the well. Parties taking over a well as provided herein shall tender to each of the other parties its proportionate share of the value of the well's salvable material and equipment, determined in accordance with the provisions of Exhibit "C," less the estimated cost of salvaging and the estimated cost of plugging and abandoning and restoring the surface; provided, however, that in the event the estimated plugging and abandoning and surface restoration costs and the estimated cost of salvaging are higher than the value of the well's salvable material and equipment, each of the abandoning parties shall tender to the parties continuing operations their proportionate shares of the estimated excess cost. Each abandoning party shall assign to the non-abandoning parties, without warranty, express or implied, as to title or as to quantity, or fitness for use of the equipment and material, all of its interest in the wellbore of the well and related equipment, together with its interest in the Leasehold insofar and only insofar as such Leasehold covers the right to obtain production from that wellbore in the Zone then open to production. If the interest of the abandoning party is or includes and Oil any Gas Interest, such party shall execute and deliver to the non-abandoning party or parties an oil and gas lease, limited to the wellbore and the Zone then open to production, for a term of one (1) year and so long thereafter as Oil and/or Gas is produced from the Zone covered thereby, such lease to be on the form attached as Exhibit "B." The assignments or leases so limited shall encompass the Drilling Unit upon which the well is located. The payments by, and the assignments or leases to, the assignees shall be in a ratio based upon the relationship of their respective percentage of participation in the Contract Area to the aggregate of the percentages of participation in the Contract Area of all assignees. There shall be no readjustment of interests in the remaining portions of the Contract Area. Thereafter, abandoning parties shall have no further responsibility, liability, or interest in the operation of or production from the well in the Zone then open other than the royalties retained in any lease made under the terms of this Article. Upon request, Operator shall continue to operate the assigned well for the account of the non-abandoning parties at the rates and charges contemplated by this agreement, plus any additional cost and charges which may arise as the result of the separate ownership of the assigned well. Upon proposed abandonment of the producing Zone assigned or leased, the assignor or lessor shall then have the option to repurchase its prior interest in the well (using the same valuation formula) and participate in further operations therein subject to the provisions hereof. 3. Abandonment of Non-Consent Operations: The provisions of Article VI.E.1. or VI.E.2. above shall be applicable as between Consenting Parties in the event of the proposed abandonment of any well excepted from said Articles; provided, however, no well shall be permanently plugged and abandoned unless and until all parties having the right to conduct further operations therein have been notified of the proposed abandonment and afforded the opportunity to elect to take over the well in accordance with the provisions of this Article VI.E.1 and provided further, that Non-Consenting Parties who own an interest in a portion of the well shall pay their proportionate shares of abandonment and surface restoration cost for such well as provided in Article VI.B.2.(b). F. TERMINATION OF OPERATIONS: Upon the commencement of an operation for the drilling, Reworking, Sidetracking, Plugging Back, Deepening, testing, Completion or plugging of a well, including but not limited to the Initial Well, such operation shall not be terminated without consent of parties bearing 75% of the costs of such operation; provided, however, that in the event granite or other practically impenetrable substance or condition in the hole is encountered which renders further operations impractical, Operator may discontinue operations and give notice of such condition in the manner provided in Article VI.B.1, and the provisions of Article VI.B. or VI.E. shall thereafter apply to such operation, as appropriate. G. TAKING PRODUCTION IN KIND: [X] OPTION NO. 1: GAS BALANCING AGREEMENT ATTACHED Each party shall have the right to take in kind or separately dispose of its proportionate share of all Oil and Gas produced from the Contract Area, exclusive of production which may be used in development and producing operations and in preparing and treating Oil and Gas for marketing purposes and production unavoidably lost. Any extra expenditure incurred in the taking in kind or separate disposition by any party of its proportionate share of the production shall be borne by such party. Any party taking its share of production in kind shall be required to pay for only its proportionate share of such part of Operator's surface facilities which it uses. Each party shall execute such division orders and contracts as may be necessary for the sale of its interest in -10- <PAGE> A.A.P.L. FORM 610 - MODEL FORM OPERATING AGREEMENT - 1989 production from the Contract Area, and, except as provided in Article VII.B., shall be entitled to receive payment <PAGE> A.A.P.L. FORM 610 - MODEL FORM OPERATING AGREEMENT - 1989 directly from the purchaser thereof for its share of all production. If any party fails to make the arrangements necessary to take in kind or separately dispose of its proportionate share of the Oil produced from the Contract Area, Operator shall have the right, subject to the revocation at will by the party owning it, but not the obligation, to purchase such Oil and/or Gas or sell it to others at any time and from time to time, for the account of the non-taking party. Any such purchase or sale by Operator may be terminated by Operator upon at least ten (10) days written notice to the owner of said production and shall be subject always to the right of the owner of the production upon at least ten (10) days written notice to Operator to exercise at any time its right to take in kind, or separately dispose of, its share of all Oil and/or Gas not previously delivered to a purchaser. Any purchase or sale by Operator of any other party's share of Oil and/or Gas shall be only for such reasonable periods of time as are consistent with the minimum needs of the industry under the particular circumstances, but in no event for a period in excess of one (1) year. Any such sale by Operator shall be in a manner commercially reasonable under the circumstances but Operator shall have no duty to share any existing market or to obtain a price equal to that received under any existing market. The sale or delivery by Operator of a non-taking party's share of Oil under the terms of any existing contract of Operator shall not give the non-taking party any interest in or make the non-taking party a party to said contract. No purchase shall be made by Operator without first giving the non-taking party at least ten (10) days written notice of such intended purchase and the price to be paid or the pricing basis to be used. All parties shall give timely written notice to Operator of their Gas marketing arrangements for the following month, excluding price, and shall notify Operator immediately in the event of a change in such arrangements. Operator shall maintain records of all marketing arrangements, and of volumes actually sold or transported, which records shall be made available to Non-Operators upon reasonable request. In the event one or more parties' separate disposition of its share of the Gas causes split-stream deliveries to separate pipelines and/or deliveries which on a day-to-day basis for any reason are not exactly equal to a party's respective proportionate share of total Gas sales to be allocated to it, the balancing or accounting between the parties shall be in accordance with any Gas balancing agreement between the parties hereto, whether such an agreement is attached as Exhibit "E" or is a separate agreement. Operator shall give notice to all parties of the first sales of Gas from any well under this agreement. ARTICLE VII. EXPENDITURES AND LIABILITY OF PARTIES A. LIABILITY OF PARTIES: The liability of the parties shall be several, not joint or collective. Each party shall be responsible only for its obligations, and shall be liable only for its proportionate share of the costs of developing and operating the Contract Area. Accordingly, the liens granted among the parties in Article VII.B. are given to secure only the debts of each severally, and no party shall have any liability to third parties hereunder to satisfy the default of any other party in the payment of any expense or obligation hereunder. It is not the intention of the parties to create, nor shall this agreement be construed as creating, a mining or other partnership, joint venture, agency relationship or association, or to render the parties liable as partners, co-venturers, or principals. In their relations with each other under this agreement, the parties shall not be considered fiduciaries or to have established a confidential relationship but rather shall be free to act on an arm's-length basis in accordance with their own respective self-interest, subject, however, to the obligation of the parties to act in good faith in their dealings with each other with respect to activities hereunder. -11- <PAGE> A.A.P.L. FORM 610 - MODEL FORM OPERATING AGREEMENT - 1989 B. LIENS AND SECURITY INTERESTS: Each party grants to the other parties hereto a lien upon any interest it now owns or hereafter acquires in Oil and Gas Leases and Oil and Gas Interests in the Contract Area, and a security interest and/or purchase money security interest in any interest it now owns or hereafter acquires in the personal property and fixtures on or used or obtained for use in connection therewith, to secure performance of all of its obligations under this agreement including but not limited to payment of expense, interest and fees, the proper disbursement of all monies paid hereunder, the assignment or relinquishment of interest in Oil and Gas Leases as required hereunder, and the proper performance of operations hereunder. Such lien and security interest granted by each party hereto shall include such party's leasehold interests, working interests, operating rights, and royalty and overriding royalty interests in the Contract Area now owned or hereafter acquired and in lands pooled or unitized therewith or otherwise becoming subject to this agreement, the Oil and Gas when extracted therefrom and equipment situated thereon or used or obtained for use in connection therewith (including, without limitation, all wells, tools, and tubular goods), and accounts (including, without limitation, accounts arising from gas imbalances or from the sale of Oil and/or Gas at the wellhead), contract rights, inventory and general intangibles relating thereto or arising therefrom, and all proceeds and products of the foregoing. To perfect the lien and security agreement provided herein, each party hereto shall execute and acknowledge the recording supplement and/or any financing statement prepared and submitted by any party hereto in conjunction herewith or at any time following execution hereof, and Operator is authorized to file this agreement or the recording supplement executed herewith as a lien or mortgage in the applicable real estate records and as a financing statement with the proper officer under the Uniform Commercial Code in the state in which the Contract Area is situated and such other states as Operator shall deem appropriate to perfect the security interest granted hereunder. Any party may file this agreement, the recording supplement executed herewith, or such other documents as it deems necessary as a lien or mortgage in the applicable real estate records and/or a financing statement with the proper officer under the Uniform Commercial Code. Each party represents and warrants to the other parties hereto that the lien and security interest granted by such party to the other parties shall be a first and prior lien, and each party hereby agrees to maintain the priority of said lien and security interest against all persons acquiring an interest in Oil and Gas Leases and Interests covered by this agreement by, through or under such party. All parties acquiring an interest in Oil and Gas Leases and Oil and Gas Interests covered by this agreement, whether by assignment, merger, mortgage, operation of law, or otherwise, shall be deemed to have taken subject to the lien and security interest granted by this Article VII.B. as to all obligations attributable to such interest hereunder whether or not such obligations arise before or after such interest is acquired. To the extent that parties have a security interest under the Uniform Commercial Code of the state in which the Contract Area is situated, they shall be entitled to exercise the rights and remedies of a secured party under the Code. The bringing of a suit and the obtaining of judgment by a party for the secured indebtedness shall not be deemed an election of remedies or otherwise affect the lien rights or security interest as security for the payment thereof. In addition, upon default by any party in the payment of its share of expenses, interests or fees, or upon the improper use of funds by the Operator, the other parties shall have the right, without prejudice to other rights or remedies, to collect from the purchaser the proceeds from the sale of such defaulting party's share of Oil and Gas until the amount owed by such party, plus interest as provided in "Exhibit C," has been received, and shall have the right to offset the amount owed against the proceeds from the sale of such defaulting party's share of Oil and Gas. All purchasers of production may rely on a notification of default from the non-defaulting party or parties stating the amount due as a result of the default, and all parties waive any recourse available against purchasers for releasing production proceeds as provided in this paragraph. If my Party fails to pay its share of cost within one hundred twenty (120) days after rendition of a statement therefor by Operator, the non-defaulting parties, including Operator, shall upon request by Operator, pay the unpaid amount in proportion that the interest of each such party bears to the interest of all such parties. The amount paid by each party so paying its share of the unpaid amount shall be secured by the liens and security rights described in Article VII-B., and each paying party may independently pursue any remedy available hereunder or otherwise. If any party does not perform all of its obligations hereunder, and the failure to perform subjects such party to foreclosure or execution proceedings pursuant to the provisions of this agreement, to the extent allowed by governing law, the defaulting party waives any available right of redemption from and after the date of judgment, any required valuation or appraisement of the mortgaged or secured property prior to sale, any available right to stay execution or to require a marshaling of assets and any required bond in the event a receiver is appointed. In addition, to the extent permitted by applicable law, each party hereby grants to the other parties a power of sale as to any property that is subject to the lien and security rights granted hereunder, such power to be exercised in the manner provided by applicable law or otherwise in a commercially reasonable manner and upon reasonable notice. Each party agrees that the other parties shall be entitled to utilize the provisions of Oil and Gas lien law or other lien law of any state in which the Contract Area is situated to enforce the obligations of each party hereunder. Without limiting the generality of the foregoing, to the extent permitted by applicable law, Non-Operators agree that Operator may invoke or utilize the mechanics' or materialmen's lien law of the state in which the Contract Area is situated in order to secure the payment to Operator of any sum due hereunder for services performed or materials supplied by Operator. C. ADVANCES: Operator, at its election, shall have the right from time to time to demand and receive from one or more of the other parties payment in advance of their respective shares of the estimated amount of the expense to be incurred in operations hereunder during the next succeeding month, which right may be exercised only by submission to each such party of an itemized statement of such estimated expense, together with an invoice for its share thereof. Each such statement and invoice for the payment in advance of estimated expense shall be submitted on or before the 20th day of the next preceding month. Each party shall pay to Operator its proportionate share of such estimate within fifteen (15) days after such estimate and invoice is received. If any party fails to pay its share of said estimate within said time, the amount due shall bear interest as provided in Exhibit "C" until paid. Proper adjustment shall be made monthly between advances and actual expense to the end that each party shall bear and pay its proportionate share of actual expenses incurred, and no more. D. DEFAULTS AND REMEDIES: If any party fails to discharge any financial obligation under this agreement, including without limitation the failure to make any advance under the preceding Article VII.C. or any other provision of this agreement, within the period required for such payment hereunder, then in addition to the remedies provided in Article VII.B. or elsewhere in this agreement, the remedies specified below shall be applicable. For purposes of this Article VII.D., all notices and elections shall be delivered -12- <PAGE> A.A.P.L. FORM 610 - MODEL FORM OPERATING AGREEMENT - 1989 only by Operator, except that Operator shall deliver any such notice and election requested by a non-defaulting Non-Operator, and when Operator is the party in default, the applicable notices and elections can be delivered by any Non-Operator. Election of any one or more of the following remedies shall not preclude the subsequent use of any other remedy specified below or otherwise available to a non-defaulting party. 1. Suspension of Rights: Any party may deliver to the party in default a Notice of Default, which shall specify the default, specify the action to be taken to cure the default, and specify that failure to take such action will result in the exercise of one or more of the remedies provided in this Article. If the default is not cured within thirty (30) days of the delivery of such Notice of Default, all of the rights of the defaulting party granted by this agreement may upon notice be suspended until the default is cured, without prejudice to the right of the non-defaulting party or parties to continue to enforce the obligations of the defaulting party previously accrued or thereafter accruing under this agreement. If Operator is the party in default, the Non-Operators shall have in addition the right, by vote of Non-Operators owning a majority in interest in the Contract Area after excluding the voting interest of Operator, to appoint a new Operator effective immediately. The rights of a defaulting party that may be suspended hereunder at the election of the non-defaulting parties shall include, without limitation, the right to receive information as to any operation conducted hereunder during the period of such default, the right to elect to participate in an operation proposed under Article VI.B. of this agreement, the right to participate in an operation being conducted under this agreement even if the party has previously elected to participate in such operation, and the right to receive proceeds of production from any well subject to this agreement. 2. Suit for Damages: Non-defaulting parties or Operator for the benefit of non-defaulting parties may sue (at joint account expense) to collect the amounts in default, plus interest accruing on the amounts recovered from the date of default until the date of collection at the rate specified in Exhibit "C" attached hereto. Nothing herein shall prevent any party from suing any defaulting party to collect consequential damages accruing to such party as a result of the default. 3. Deemed Non-Consent: The non-defaulting party may deliver a written Notice of Non-Consent Election to the defaulting party at any time after the expiration of the thirty-day cure period following delivery of the Notice of Default, in which event if the billing is for the drilling a new well or the Plugging Back, Sidetracking, Reworking or Deepening of a well which is to be or has been plugged as a dry hole, or for the Completion or Recompletion of any well, the defaulting party will be conclusively deemed to have elected not to participate in the operation and to be a Non-Consenting Party with respect thereto under Article VI.B. or VI.C., as the case may be, to the extent of the costs unpaid by such party, notwithstanding any election to participate theretofore made. Until the delivery of such Notice of Non-Consent Election to the defaulting party, such party shall have the right to cure its default by paying its unpaid share of costs plus interest at the rate set forth in Exhibit "C," provided, however, such payment shall not prejudice the rights of the non-defaulting parties to pursue remedies for damages incurred by the non-defaulting parties as a result of the default. Any interest relinquished pursuant to this Article VII.D.3. shall be offered to the non-defaulting parties in proportion to their interests, and the non-defaulting parties electing to participate in the ownership of such interest shall be required to contribute their shares of the defaulted amount upon their election to participate therein. 4. Advance Payment: If a default is not cured within thirty (30) days of the delivery of a Notice of Default, Operator, or Non-Operators if Operator is the defaulting party, may thereafter require advance payment from the defaulting party of such defaulting party's anticipated share of any item of expense for which Operator, or Non-Operators, as the case may be, would be entitled to reimbursement under any provision of this agreement, whether or not such expense was the subject of the previous default. Such right includes, is not limited to, the right to require advance payment for the estimated costs of drilling a well or Completion of a well as to which an election to participate in drilling or Completion has been made. If the defaulting party fails to pay the required advance payment, the non-defaulting parties may pursue any of the remedies provided in the Article VII.D. or any other default remedy provided elsewhere in this agreement. Any excess of funds advanced remaining when the operation is completed and all costs have been paid shall be promptly returned to the advancing party. 5. Costs and Attorneys' Fees: In the event any party is required to bring legal proceedings to enforce any financial obligation of a party hereunder, the prevailing party in such action shall be entitled to recover all court costs, costs of collection, and a reasonable attorney's fee, which the lien provided for herein shall also secure. E. RENTALS, SHUT-IN WELL PAYMENTS AND MINIMUM ROYALTIES: Rentals, shut-in well payments and minimum royalties which may be required under the terms of any lease shall be paid by the party or parties who subjected such lease to this agreement at its or their expense. In the event two or more parties own and have contributed interests in the same lease to this agreement, such parties may designate one of such parties to make said payments for and on behalf of all such parties. Any party may request, and shall be entitled to receive, proper evidence of all such payments. In the event of failure to make proper payment of any rental, shut-in well payment or minimum royalty through mistake or oversight where such payment is required to continue the lease in force, any loss which results from such non-payment shall be borne in accordance with the provisions of Article IV.B.2. Operator shall notify Non-Operators of the anticipated completion of a shut-in well, or the shutting in or return to production of a producing well, at least five (5) days (excluding Saturday, Sunday, and legal holidays) prior to taking such action, or at the earliest opportunity permitted by circumstances, but assumes no liability for failure to do so. In the event of failure by Operator to so notify Non-Operators, the loss of any lease contributed hereto by Non-Operators for failure to make timely payments of any shut-in well payment shall be borne jointly by the parties hereto under the provisions of Article IV.B.3. F. TAXES: Beginning with the first calendar year after the effective date hereof, Operator shall render for ad valorem taxation all property subject to this agreement which by law should be rendered for such taxes, and it shall pay all such taxes assessed thereon before they become delinquent. Prior to the rendition date, each Non-Operator shall furnish Operator information as to burdens (to include, but not be limited to, royalties, overriding royalties and production payments) on Leases and Oil and Gas Interests contributed by such Non-Operator. If the assessed valuation of any Lease is reduced by reason of its being subject to outstanding excess royalties, overriding royalties or production payments, the reduction in ad valorem taxes resulting therefrom shall inure to the benefit of the owner or owners of such Lease, and Operator shall adjust the charge to such owner or owners so as to reflect the benefit of such reduction. If the ad valorem taxes are based in whole or in part upon separate valuations of each party's working interest, then notwithstanding anything to the contrary herein, charges to the joint account shall be made and paid by the parties hereto in accordance with the tax value generated by each party's working interest. Operator shall bill the other parties for their proportionate shares of all tax payments in the manner provided in Exhibit "C." -13- <PAGE> A.A.P.L. FORM 610 - MODEL FORM OPERATING AGREEMENT - 1989 If Operator considers any tax assessment improper, Operator may, at its discretion, protest within the time and manner prescribed by law, and prosecute the protest to a final determination, unless all parties agree to abandon the protest prior to final determination. During the pendency of administrative or judicial proceedings, Operator may elect to pay, under protest, all such taxes and any interest and penalty. When any such protested assessment shall have been finally determined, Operator shall pay the tax for the joint account, together with any interest and penalty accrued, and the total cost shall then be assessed against the parties, and be paid by them, as provided in Exhibit "C." Each party shall pay or cause to be paid all production, severance, excise, gathering and other taxes imposed upon or with respect to the production or handling of such party's share of Oil and Gas produced under the terms of this agreement. ARTICLE VIII. ACQUISITION, MAINTENANCE OR TRANSFER OF INTEREST A. SURRENDER OF LEASES: The Leases covered by this agreement, insofar as they embrace acreage in the Contract Area, shall not be surrendered in whole or in part unless all parties consent thereto. However, should any party desire to surrender its interest in any Lease or in any portion thereof, such party shall give written notice of the proposed surrender to all parties, and the parties to whom such notice is delivered shall have thirty (30) days after delivery of the notice within which to notify the party proposing the surrender whether they elect to consent thereto. Failure of a party to whom such notice is delivered to reply within said 30-day period shall constitute a consent to the surrender of the Leases described in the notice. If all parties do not agree or consent thereto, the party desiring to surrender shall assign, without express or implied warranty of title, all of its interest in such Lease, or portion thereof, and any well, material and equipment which may be located thereon and any rights in production thereafter secured, to the parties not consenting to such surrender. If the interest of the assigning party is or includes an Oil and Gas Interest, the assigning party shall execute and deliver to the party or parties not consenting to such surrender an oil and gas lease covering such Oil and Gas Interest for a term of one (1) year and so long thereafter as Oil and/or Gas is produced from the land covered, thereby. Upon such assignment or lease, the assigning party shall be relieved from all obligations thereafter accruing, but not theretofore accrued, with respect to the interest assigned or leased and the operation of any well attributable thereto, and the assigning party shall have no further interest in the assigned or leased premises and its equipment and production other than the royalties retained in any lease made under the terms of this Article. The party assignee or lessee shall pay to the party assignor or lessor the reasonable salvage value of the latter's interest in any well's salvable materials and equipment attributable to the assigned or leased acreage. The value of all salvable materials and equipment shall be determined in accordance with the provisions of Exhibit "C," less the estimated cost of salvaging and the estimated cost of plugging and abandoning and restoring the surface. If such value is less than such costs, then the party assignor or lessor shall pay to the party assignee or lessee the amount of such deficit. If the assignment or lease is in favor of more than one party, the interest shall be shared by such parties in the proportions that the interest of each bears to the total interest of all such parties. If the interest of the parties to whom the assignment is to be made varies according to depth, then the interest assigned shall similarly reflect such variances. Any assignment, lease or surrender made under this provision shall not reduce or change the assignor's, lessor's or surrendering party's interest as it was immediately before the assignment, lease or surrender in the balance of the Contract Area; and the acreage assigned, leased or surrendered, and subsequent operations thereon, shall not thereafter be subject to the terms and provisions of this agreement but shall be deemed subject to an Operating Agreement in the form of this agreement. B. RENEWAL OR EXTENSION OF LEASES: If any party secures a renewal or replacement of an Oil and Gas Lease or Interest subject to this agreement, then all other parties shall be notified promptly upon such acquisition or, in the case of a replacement Lease taken before expiration of an existing Lease, promptly upon expiration of the existing Lease. The parties notified shall have the right for a period of thirty (30) days following delivery of such notice in which to elect to participate in the ownership of the renewal or replacement Lease, insofar as such Lease affects lands within the Contract Area, by paying to the party who acquired it their proportionate shares of the acquisition cost allocated to that part of such Lease within the Contract Area, which shall be in proportion to the interest held at that time by the parties in the Contract Area. Each party who participates in the purchase of a renewal or replacement Lease shall be given an assignment of its proportionate interest therein by the acquiring party. If some, but less than all, of the parties elect to participate in the purchase of a renewal or replacement Lease, it shall be owned by the parties who elect to participate therein, in a ratio based upon the relationship of their respective percentage of participation in the Contract Area to the aggregate of the percentages of participation in the Contract Area of all parties participating in the purchase of such renewal or replacement Lease. The acquisition of a renewal or replacement Lease by any or all of the parties hereto shall not cause a readjustment of the interests of the parties stated in Exhibit "A," but any renewal or replacement Lease in which less than all parties elect to participate shall not be subject to this agreement but shall be deemed subject to a separate Operating Agreement in the form of this agreement. If the interests of the parties in the Contract Area vary according to depth, then their right to participate proportionately in renewal or replacement Leases and their right to receive an assignment of interest shall also reflect such depth variances. The provisions of this Article shall apply to renewal or replacement Leases whether they are for the entire interest covered by the expiring Lease or cover only a portion of its area or an interest therein. Any renewal or replacement Lease taken before the expiration of its predecessor Lease, or taken or contracted for or becoming effective within six (6) months after the expiration of the existing Lease, shall be subject to this provision so long as this agreement is in effect at the time of such acquisition or at the time the renewal or replacement Lease becomes effective; but any Lease taken or contracted for more than six (6) months after the expiration of an existing Lease shall not be deemed a renewal or replacement Lease and shall not be subject to the provisions of this agreement. The provisions in this Article shall also be applicable to extensions of Oil and Gas Leases. C. ACREAGE OR CASH CONTRIBUTIONS: While this agreement is in force, if any party contracts for a contribution of cash towards the drilling of a well or any other operation on the Contract Area, such contribution shall be paid to the party who conducted the drilling or other operation and shall be applied by it against the cost of such drilling or other operation. If the contribution be in the form of acreage, the party to whom the contribution is made shall promptly tender an assignment of the acreage, without warranty of title, to the Drilling Parties in the proportions said Drilling Parties shared the cost of drilling the well. Such acreage shall become a separate Contract Area and, to the extent possible, be governed by provisions identical to this agreement. Each party shall promptly notify all other parties of any acreage or cash contributions it may obtain in support of any well or any other operation on the Contract Area. The above provisions shall also be applicable to optional rights to earn acreage outside the Contract Area which are in support of well drilled inside Contract Area. -14- <PAGE> A.A.P.L. FORM 610 - MODEL FORM OPERATING AGREEMENT - 1989 If any party contracts for any consideration relating to disposition of such party's share of substances produced hereunder, such consideration shall not be deemed a contribution as contemplated in this Article VIII.C. D.

Right to Take and Market Gas During any period or periods when any party hereto does not take, has no market for, or the market of a party is not sufficient to take that party's full share of the Gas produced from a Well located on the Contract Area, or such party's purchaser otherwise fails to take such party's share of Gas produced from any such Well in the Contract Area, resulting in such party becoming Underproduced (such party being herein referred to as an "Underproduced party") the other party or parties shall be entitled, but not required to produce from said Well in the Contract Area and take or deliver to their respective purchaser(s), each month, all or a part of that portion of the allowable Gas production assigned to such Well by the regulatory body having jurisdiction. Any party so taking or delivering Gas which results in such party becoming Overproduced is herein referred to as an "Overproduced party". Those parties which are capable of taking and/or marketing quantities of Gas allocable to an Underproduced party, in the absence of any other agreement between them, shall each take a share of the Gas attributed to the Underproduced party or parties in the direct proportion that their respective interests bear to the total interest of all parties taking Gas who are also considered Overproduced. All parties hereto shall share in and own the liquid hydrocarbons recovered from such Gas by primary separation equipment in accordance with their respective interests and subject to the terms of the above described Operating Agreement, whether or not such parties are actually taking and/or marketing Gas at such time. B. Making Up Underproduction Each party failing to market its share of the total volume of Gas produced or failing to take its full share of the total volume of Gas produced shall be considered Underproduced and shall be credited with Gas in storage equal to its percentage share of the total volume of Gas produced under this Agreement, less that portion of the Gas actually marketed or taken by such party, gas used in operations, vented, or lost. Any Underproduced party shall endeavor to bring its taking of Gas into a Balanced condition. Upon at least 30 days written notice to the Operator, any Underproduced party may thereafter begin taking or delivering to its purchaser its full share of the Gas produced from a Well (less any used in operations, vented, or lost). To allow an Underproduced party to balance, upon 30 days written notice, an Underproduced party shall be entitled to take or deliver to a purchaser its full share of Gas produced from such Well (less any used in operations, vented, or lost) plus, (i) for the months of March, April, May, June, July, August, September and October only of any calendar year or years during which this agreement may be in place, an amount up to an additional fifty percent (50%) of the monthly quantity of gas attributable to the Overproduced party or parties, or (ii) for the months of November, December, January and February only of any calendar year or years during which this agreement may be in place, an amount up to an additional twenty-five percent (25%) of the monthly quantity of Gas attributable to the Overproduced party or parties, beginning the first of the month immediately following the twenty (20) days written notice. <PAGE> If more than one Underproduced party is entitled to take additional Gas, they shall divide the additional Gas in proportion to their respective Underproduced accounts. The first Gas made up shall be assumed to be the first Gas Underproduced. C. Gas Balance Reporting Each party taking Gas shall furnish or cause to be furnished to the Operator a monthly written statement of Gas volumes taken and the identity of its Gas purchaser, if any, no later than thirty (30) days after the production month. Operator shall not be required to adjust its Gas accounting statements reflecting a different Gas purchaser until the first day of the month following the month in which such notice is received by the Operator. The Operator will maintain appropriate accounting on a monthly and cumulative basis of the quantities of Gas each party is entitled to take and/or market and the quantities of Gas taken and/or marketed by each of the parties to their respective Gas purchasers. With respect to Gas purchased from or transported for more than one party by or through one pipeline connected to the Well, each party selling to or transporting through such one pipeline shall furnish to Operator or cause the pipeline owner to furnish to Operator monthly volume statements showing the split of ownership through such pipeline's sales or pipeline inlet meter during the preceding calendar month. Within ninety (90) days after the end of each producing calendar month, the Operator shall furnish each Party a statement showing the status of the Overproduced and Underproduced accounts of all parties. To determine respective volumes of Gas taken by separate gas pipeline connected to the Wel1, measurement of Gas for overproduction and underproduction shall be accomplished by use of sales meters and well measurement equipment which shall be in accordance with AGA requirements. Each party to this agreement agrees that it will not utilize any information obtained hereunder for any purpose other than implementing or administering the terms of this Gas Balancing Agreement. D. Royalty and Production Tax At all times while Gas is produced from the Contract Area, unless otherwise required by any State or Federal law or regulations, each party shall pay or cause to be paid all royalty due and payable on its share of Gas production as if each party were taking or delivering to a Gas purchaser its share of Gas production. Each party agrees to hold each other party harmless from any and all claims for royalty payments asserted by its royalty owners. The term "royalty owner" shall include owners of royalty, overriding royalties, production payments, and similar interests payable out of production. Each party producing and taking or delivering Gas to its Gas purchaser shall pay, or cause to be paid, all production and severance taxes due on all volumes of Gas actually taken or sold by such party. IV. Cash Settlement A. Final Cash Balancing Should production of gas from the Contract Area be permanently discontinued before the gas accounts are balanced, the Operator shall make a final determination of the volume of the last accrued over- and underproduction, if any, as of the date of such permanent discontinuance and the identity of the party(s) who are over- or underproduced. A cash settlement will then be made between <PAGE> the Underproduced and Overproduced parties. In making such settlement, the Underproduced parties shall be paid a sum of money by the Overproduced parties equal to the value, computed as hereafter set forth, of the unrecouped cumulative balance of overproduction, less applicable taxes and royalties theretofore paid. In determining the value of the unrecouped cumulative balance of overproduction, beginning with the most recent month in which the Overproduced parties took a volume of gas in excess of the quantity to which such parties were entitled, hereafter called "overage," the volume of overage during such month shall be multiplied times the actual prices received for such overage during such month. The same calculation shall be made for the next preceding month in which an overage occurred and for each preceding month (progressing backward in time) in which an overage occurred until the total volume of the overages for these months equals the total volume of the unrecouped cumulative balance of overproduction for purposes of the cash settlement herein contemplated. Within ninety (90) days of permanent discontinuance, the Operator will supply to the Non-operator final volume gas balancing statements. Within one hundred eighty (180) days of permanent discontinuance, the Overproduced parties will pay or cause to be paid to the Underproduced parties their share of overage. Operator assumes no liability with respect to any such third party payments due any Underproduced party. If refunds are later required by any governmental authority, each party shall be accountable for its respective share of such refunds as finally balanced hereunder. B. Collection and Distribution Operator shall provide within thirty (30) days of permanent termination of Gas production a final accounting of the Gas balance to all parties hereto. Overproduced parties, within thirty (30) days of receipt of the final accounting of the Gas balance, shall provide Operator with a monthly statement of volume for each month during which overproduction occurred that has not been made-up. Within thirty (30) days after the receipt of such monthly statements for Overproduced parties, Operator shall calculate and invoice each Overproduced party for its share of the cash settlement, based on said volume statements, and the Cash Out Value due each Underproduced party. Overproduced parties shall make settlement, based on the invoiced amount, to the Operator within thirty (30) days after receipt of said invoice. Such payment shall relieve an Overproduced party of liability to any other party for the sums paid. Operator shall promptly distribute the funds it receives to the Underproduced parties in that proportion that each Underproduced party's volume of gas in storage bears to the total of all Underproduced parties volumes for Gas in storage. C. Responsibility and Liability for Collection Operator shall not be liable to any Underproduced party for the failure of any Overproduced party to any amounts owed pursuant to the terms hereof. In the event that any party fails to pay any sum due under the terms hereof after demand therefore by the Operator, the Operator may turn responsibility for the collection of such sum to the party or parties to whom it is owed, and Operator shall have no further responsibility in the event that such sums are not paid. Any party shall have the right after expiration of thirty (30) days after the Operator shall have provided a final accounting of the Gas balance to all parties hereto to demand on thirty (30) days advance written notice to both Operator and all Overproduced parties that any payments due to such party for such party's Underproduced volumes shall be paid directly to such party by the Overproduced party(s), rather than being paid through Operator. In the event that any Overproduced party pays to Operator any sums due to an Underproduced party at any time after thirty (30) days following the receipt of such written notification of a demand that such <PAGE> Underproduced party receive such payment directly, the Overproduced party(s) shall continue to be liable to such Underproduced party for any sums so paid, until such payment is actually received by such Underproduced party. In no event shall Operator be liable or responsible for any amount of cash settlement based on a value asserted by an Underproduced party different than the value calculated based on the volume statements and Cash Out Value provided by the Overproduced party or parties. D. Ownership Changes In the event an Overproduced party intends to sell, assign, exchange or otherwise transfer any of its interest in a Well located on the Contract area, such Overproduced party shall notify in writing the other working interest owners who are parties hereto in such Well of such fact within forty-five (45) days prior to closing the transaction. Any Underproduced party may demand of such Overproduced party in writing, within twenty (20) days after receipt of the Overproduced party's notice of intent to sell, assign, exchange or otherwise transfer its interest in a Well, a cash settlement of its underproduction attributed to such Overproduced party's Overproduction in the Well. Any Underproduced party electing to cash settle with the Overproduced party shall thereby indemnify and hold the Overproduced party harmless against any causes of action, claims, losses or other actions which may be claimed by any third party, including, but not limited to, any purchaser of the Gas of the Underproduced party, as a result of the cash settlement. The Operator shall be notified of any such demand and of any cash settlement pursuant to this Paragraph IV.D., and the Gas balance accounts of the parties shall be adjusted accordingly. Any cash settlement pursuant to this Paragraph IV.D shall be on the same basis as otherwise set forth in Paragraphs IV.A. through IV.C. hereof. The provision of this Paragraph IV.D shall not be applicable in the event an Overproduced party has mortgaged its interest, or disposed of its interests by merger, reorganization, consolidation, or sale of substantially all of its assets to a subsidiary or parent company, or to any company in which any parent or subsidiary owns a majority of the stock of such company. V. Miscellaneous A. Term This agreement shall remain in force and effect as long as the Operating Agreement to which it is attached remains in force and effect, and thereafter until the Gas balance accounts between the parties are settled in full, and shall inure to the benefit of and be binding upon the parties hereto, their heirs, successors, legal representatives and assigns. <PAGE> B. Expenses Nothing herein shall change or affect each party's obligations to pay its proportionate share of all costs and liabilities incurred in operations on the Contract Area as its share thereof is set forth in the Operating Agreement to which this Agreement is attached. C. Well Tests Nothing herein shall be construed to deny any party the right, from time to time, to produce and take or deliver to its Gas purchaser up to one hundred percent (100%) of the entire well stream to meet the deliverability test required by its Gas purchaser, provided that such tests are reasonable in light of overall industry standards. D. Monitoring of Takes of Production Each party shall, at all times, use its best efforts to regulate its takes and deliveries from each well on said Contract Area so that no well will be shut-in for overproducing the allowable assigned thereto by the regulatory body having jurisdiction. Additionally, each party shall communicate, as necessary, the contents of this agreement to its respective Gas purchaser(s) or transporter(s) and shall monitor its deliveries to its respective Gas Purchaser(s) or transporter(s) so as to ensure to the greatest extent practicable that its Gas purchaser(s) or transporter(s) does not take Gas in excess of the quantities provided for herein. E. Method of Tax Accounting In the event Internal Revenue Service regulations require a uniform method of computing taxable income by all parties, each party agrees to compute and report income to the Internal Revenue Service based on the quantity of Gas taken for its account (the cumulative method) in accordance with such regulations. <PAGE> EXHIBIT "F" ATTACHED TO AND MADE PART OF THAT CERTAIN JOINT OPERATING AGREEMENT DATED EFFECTIVE OCTOBER 1, 200l BY AND BETWEEN UNION OIL COMPANY OF CALIFORNIA, AS OPERATOR, AND IVANHOE ENERGY (USA) INC., AS NON-OPERATOR.

The amount paid by each party so paying its share of the unpaid amount shall be secured by the liens and security rights described in this paragraph 3 and in the Operating Agreement, and each paying party may independently pursue any remedy available under the Operating Agreement or otherwise. E. If any party does not perform all of its obligations under this agreement or the Operating Agreement, and the failure to perform subjects such party to foreclosure or execution proceedings pursuant to the provisions of this agreement or the Operating Agreement, to the extent allowed by governing law, the defaulting party waives any available right of redemption from and after the date of judgment, any required valuation or appraisement of the mortgaged or secured property prior to sale, any available right to stay execution or to require a marshalling of assets and any required bond in the event a receiver is appointed. In addition, to the extent permitted by applicable law, each party hereby grants to the other parties a power of sale as to any property that is subject to the lien and security rights granted hereunder or under the Operating Agreement, such power to be exercised in the manner provided by applicable law or otherwise in a commercially reasonable manner and upon reasonable notice. F. The lien and security interest granted in this paragraph 3 supplements identical rights granted under the Operating Agreement. G. To the extent permitted by applicable law, Non-Operators agree that Operator may invoke or utilize the mechanics' or materialmen's lien law of the state in which the Contract Area is situated in order to secure the payment to Operator of any sum due under this agreement and the Operating Agreement for services performed or materials supplied by Operator.
