Purchase and Sale Agreement Page 4 5 ARTICLE 2 - PURCHASE PRICE 2.1 PURCHASE PRICE; METHOD OF PAYMENT; DEPOSIT (a) The purchase price for the Assets shall be $16,000,000.00 (the "Purchase Price"), which amount shall be adjusted as provided in Section 2.2. (b) All amounts required under this Article 2 to be paid by any party hereto to another party hereto shall be made by wire transfer of immediately available funds to an account designated by the payee thereof, which designation shall be made not later than two Business Days prior to the date such payment is due. (c) On July 21, 1999, Purchaser paid to ARCO, and ARCO acknowledges receipt of, a performance deposit in the amount of $2,000,000.00 (the "Deposit"), which amount shall be held by ARCO and distributed as follows: (i) if this Agreement is terminated as provided in Section 12.1(a) or Section 12.1(b), the Deposit shall be returned by ARCO to Purchaser; (ii) if this Agreement is terminated by either party pursuant to the termination right provided in Section 12.1(c) and at such time all of Purchaser's conditions to Closing as set forth in Article 9 have not been satisfied or waived (and such failure is not due to a breach by Purchaser of its obligations hereunder), the Deposit shall be returned by ARCO to Purchaser; (iii) if this Agreement is terminated by either party pursuant to the termination right provided in Section 12.1(c) and at such time all of Purchaser's conditions to Closing as set forth in Article 9 have been satisfied or waived, the Deposit shall be retained by ARCO; and (iv) if Closing occurs, ARCO shall apply the Deposit towards the Purchase Price. ARCO and Purchaser acknowledge and agree that until ARCO is obligated to distribute the Deposit as provided above, ARCO may invest the Deposit in such investments as it deems appropriate and any income resulting therefrom shall be the property of ARCO and not Purchaser. (d) Purchaser further acknowledges and agrees that if ARCO becomes entitled to the Deposit pursuant to the provisions of Section 2.1(c)(iii), ARCO's damages under such circumstances would be difficult to ascertain and ARCO shall be entitled to liquidated damages in an amount equal to the Deposit. Accordingly, the retention by ARCO of the Deposit as provided in Section 2.1(c)(iii) above shall be deemed to constitute the payment by Purchaser to ARCO of such liquidated damages, but in no event shall such retention of the Deposit or deemed payment of liquidated damages constitute or be construed as a penalty. If ARCO becomes entitled to retain the Deposit pursuant to Section 2.1(c)(iii) above, such retention shall constitute the sole remedy of ARCO under this Agreement for Purchaser's failure to consummate the transactions contemplated hereunder (such limitation shall not limit the rights of ARCO under any of the provisions of this Agreement that survive a termination and continue in full force and effect pursuant to Section 12.2). 2.2 ADJUSTMENTS TO PURCHASE PRICE. The Purchase Price for the Assets shall be adjusted as follows (the resulting amount being herein referred to as the "Adjusted Purchase Price"): (a) The Purchase Price shall be increased by an amount equal to the sum of the following amounts (determined without duplication and on an accrual basis in accordance with generally accepted accounting principles consistently applied): (i) the amount of all expenses (net to ARCO's interest) incurred and paid or to be paid by or on behalf of ARCO that are attributable to the ownership or operation of the Assets and to the period of time from and after the Effective Date, including without limitation, capital expenditures, royalties, ad valorem, property and similar taxes and assessments, severance, sales and production taxes (but excluding income taxes and franchise taxes), rentals and similar charges, amounts billed under applicable operating agreements and prepaid expenses; and (ii) an amount equal to the value allocated to all Title Increases in accordance with Section 3.5(c). (b) The Purchase Price shall be decreased by an amount equal to the sum of the following amounts (determined without duplication and on an accrual basis in accordance with generally accepted accounting principles consistently applied): (i) the amount of all proceeds (net to ARCO's interest) earned and received or to be received by or on behalf of ARCO (other than proceeds from the exercise by third parties of preferential rights to purchase all or any portion of the Leasehold Interests) that are attributable to the ownership or operation of the Assets after the Effective Date and to the Purchase and Sale Agreement Page 5 6 period of time from and after the Effective Date, it being agreed that such amount shall not include proceeds from the sale subsequent to the Effective Date of merchantable hydrocarbons in storage above the pipeline connection at the Effective Date; (ii) an amount equal to the value of all Title Defects and excluded Leasehold Interests as determined in accordance with Sections 3.4-3.7; and (iii) an amount equal to the value of the Leasehold Interests with respect to which preferential purchase rights have been exercised prior to Closing in accordance with Section 3.9. 2.3 PAYMENT AND CALCULATION OF ESTIMATED ADJUSTED PURCHASE PRICE; PAYMENT AT CLOSING. (a) ARCO shall prepare and deliver to Purchaser, at least three "Business Days" (which term shall mean any day except a Saturday, Sunday or other day on which commercial banks in New York, New York, or Dallas, Texas are required or authorized by law to be closed) prior to the Closing Date, ARCO's estimate of the Adjusted Purchase Price to be paid at Closing, together with a statement setting forth ARCO's estimate of the amount of each adjustment to the Purchase Price to be made pursuant to Section 2.2. The parties shall negotiate in good faith and attempt to agree on such estimated adjustments prior to Closing. In the event any estimated adjustment amounts are not agreed upon prior to Closing, the estimate of the Adjusted Purchase Price for purposes of Closing shall be calculated based on ARCO's and Purchaser's agreed upon estimated adjustments. (b) At Closing, Purchaser shall pay to ARCO the estimated Adjusted Purchase Price determined as set forth in Section 2.3(a) (such estimated Adjusted Purchase Price being herein referred to as the "Estimated Adjusted Purchase Price"), less an amount equal to the Deposit. 2.4 POST-CLOSING ADJUSTMENT. Within five Business Days after the final determination of the Adjusted Purchase Price in accordance with Section 11.1 or otherwise, Purchaser shall pay to ARCO or ARCO shall pay to Purchaser, as the case may be, the amount by which such final Adjusted Purchase Price is greater than or less than, respectively, the Estimated Adjusted Purchase Price. 2.5 ALLOCATION OF PURCHASE PRICE. ARCO and Purchaser agree to the following allocation of the Purchase Price among the Assets sold hereunder based upon the estimated value for federal income tax purposes of the Assets as of the Closing Date: Interests relating to leasehold other than tangible equipment and facilities (Leasehold) 70% Interests relating to tangible equipment and facilities (Tangibles) 30% --- Total Allocation 100% Any adjustments to the Purchase Price under Section 2.2 shall ratably adjust the allocation to Leasehold and Tangibles. ARTICLE 3 - TITLE MATTERS 3.1 ACCESS TO ASSETS AND ARCO EMPLOYEES. Prior to the Closing Date, ARCO shall grant Purchaser access during ARCO's normal business hours (by appointment only) to the Assets (including all Records) and the employees of ARCO. The Records shall be made available at their present location. 3.2 DEFINITION OF MARKETABLE TITLE. As used herein, the term "Marketable Title" shall mean, in the case of the Leasehold Interests listed on Exhibit A and other Assets to which an Allocated Value is assigned on Exhibit 3.6 (each such identified other Asset being herein referred to as a "Valued Asset"), such right, title and interest (owned beneficially or of record) that, except for Permitted Encumbrances: (a) is free from reasonable doubt to the end that a prudent person engaged in the business of purchasing and owning, developing and operating producing oil and gas properties with knowledge of all of the facts and their legal bearing would be willing to accept the same; (b) entitles ARCO to receive not less than the interest set forth in Exhibit A as the "Net Revenue Interest" or "NRI" with respect to all of the oil, gas, and hydrocarbon minerals produced, saved and marketed from each unit or well, as the case may be, that relates to ARCO's producing interval in the lands and depths included within each property identified on Exhibit A under the column entitled "Property Name" (each such identified property being herein referred to as a "Property"); (c) obligates ARCO to pay costs and expenses relating to the operations on and the maintenance and development of each unit or well, as the case may be, that relates to ARCO's Purchase and Sale Agreement Page 6 7 producing interval in the lands and depths included within each Property, in an amount not greater than the "Working Interest" or "WI" set forth in Exhibit A with respect to such Property; and (d) is free and clear of any mortgages, liens, encumbrances or consent requirements; provided, however, that with respect to clauses (b) and (c) above ARCO's title shall nevertheless be deemed to constitute "Marketable Title" if (i) the difference between ARCO's actual interest and the interest set forth in Exhibit A for each unit or well included within an individual Property is 1% or less than the interest set forth in Exhibit A (by way of example, and without limiting the generality of the foregoing, if the Net Revenue Interest shown in Exhibit A for each unit or well included within a Property is 88%, ARCO will have Marketable Title to such Leasehold Interest if it is entitled to receive not less than 87.12% of all oil and gas produced from such Property) or (ii) the value of any difference between ARCO's actual interest in the interest set forth in Exhibit A (as such value is determined in accordance with Section 3.6) is less than $10,000.00. 3.3 DEFINITION OF PERMITTED ENCUMBRANCES. As used herein, the term "Permitted Encumbrances" shall mean: (a) Lessors' royalties, overriding royalties, reversionary interests and similar burdens affecting a Leasehold Interest if the net cumulative effect of such burdens does not operate to reduce the interest of ARCO with respect to all oil and gas produced from any units or wells below the "Net Revenue Interest" or "NRI" set forth in Exhibit A for the Property to which such units or wells relate; (b) Division orders and sales contracts terminable without penalty upon no more than 90 days notice to the purchaser; (c) Preferential rights to purchase and required third-party consents to assignments and similar agreements with respect to which waivers or consents are obtained from the appropriate parties or the appropriate time period for asserting the rights has expired without an exercise of such rights; (d) Materialman's, mechanic's, repairman's, employee's, contractor's, operator's, tax, and other similar liens or charges arising in the ordinary course of business for obligations that are not delinquent or that will be paid and discharged in the ordinary course of business or if delinquent, that are being contested in good faith by appropriate action; (e) All rights to consent by, required notices to, filings with, or other actions by governmental or tribal entities in connection with the sale or conveyance of oil and gas leases or interests therein; (f) Conventional rights of reassignment requiring notice to the holders of such rights; (g) Easements, rights-of-way, servitudes, permits, surface leases and other rights of third parties in respect of surface operations which individually or in the aggregate do not materially interfere with the operation, value or use of the Leasehold Interests (or portions thereof) affected thereby; (h) All other liens, charges, encumbrances, contracts, agreements, instruments, obligations, defects and irregularities affecting the Leasehold Interests or the units or wells to which they relate that individually or in the aggregate: (i) are not such as to interfere materially with the operation, value or use of the Leasehold Interests (or portion thereof) affected thereby, (ii) do not unreasonably delay the receipt or materially prevent Purchaser from receiving the proceeds of production from any of the units or wells to which the Leasehold Interests relate, (iii) do not materially reduce the interest of ARCO with respect to all oil and gas produced from any unit or well to which the Leasehold Interests relate below the "Net Revenue Interest" or "NRI" set forth in Exhibit A for the Property to which such unit or well relates, and (iv) do not materially increase ARCO's portion of the costs and expenses relating to the operations on and the maintenance and development of the lands and depths included in any unit or well to which the Leasehold Interests relate above the "Working Interest" or "WI" set forth in Exhibit A for the Property to which such unit or well relates; (i) All rights reserved to or vested in any municipality or governmental, statutory or public authority to control or regulate any of the Leasehold Interests in any manner, and all applicable laws, rules and orders of any such authority; Purchase and Sale Agreement Page 7 8 (j) Any Title Defects Purchaser may have expressly waived in writing or which are deemed to have been waived under Section 3.4 or any other matters that are included in the adjustments to the Purchase Price pursuant to Section 2.2; (k) The terms and provisions of all operating agreements, unit agreements, unit operating agreements, pooling agreements and pooling designations affecting the Leasehold Interests which are specifically listed on Exhibit A; and (l) The terms and conditions of all leases, agreements, orders, instruments and documents expressly described in or referred to in Exhibit A.; (m) The terms and conditions of all agreements with King Cad Plus for month-to-month rental of office space and/or drafting services in-lieu of rental of office space within the ARCO Longview Production Office and which shall be terminated by ARCO on or before April 1, 1999; (n) Corporate mergers between Atlantic Richfield Company, a Delaware corporation, and predecessor corporations, including, but not limited to, Atlantic Richfield Company, a Pennsylvania corporation, Hondo Oil & Gas Company, a New Mexico corporation, Sinclair Oil & Gas Corporation, a Maine corporation, Sinclair Corporation, Richfield Oil Corporation, and Houston Oil and Gas Company, even though Certificates of Corporate Merger or other evidence of such corporate merger or mergers are not recorded in the applicable county records wherein the Assets involved may be located; provided, however, that upon request, ARCO is able to provide Purchaser with photocopies of the Certificates of Corporate Merger filed with the Secretary of State of the state or states of incorporation of the merging corporation.; and (o) Production payments wherein ARCO or a predecessor corporation of ARCO is named as obligor/payor and where the principal amount of initial indebtedness is less than $5,000,000.00 and where the effective date of the production payment obligation is on or before January 1, 1972 (any such production payment referred to hereafter as an "Unreleased Production Payment"), even though a release of all obligations of ARCO or ARCO's predecessor in interest has not been filed in the county records wherein the Assets involved are located, unless Purchaser can demonstrate to ARCO by the presentation of business records, financial records or check stubs created and issued within one year of Closing that any such production payment is still being carried in an active status and all obligations of ARCO or ARCO's predecessor thereunder have not been completely satisfied. Notwithstanding anything to the contrary contained herein, ARCO does hereby agree to indemnify and hold harmless Purchaser and its affiliated parties from and against any and all claims, liabilities, losses, costs and expenses (including court costs and reasonable attorneys' fees) in related to or arising from an Unreleased Production Payment, for as long as Purchaser or its affiliated parties own the Assets affected by the Unreleased Production Payment. ARCO's obligation to indemnify Purchaser under this Section 3.3(o) is unique and personal, and as such is non-assignable and non-transferable. Further, ARCO's indemnity to Purchaser under this Section 3.3(o) shall be limited to the lesser of the Allocated Value for the affected Asset as shown on Exhibit 3.6 attached hereto, or the mutually agreed upon fair market value of the Asset at the time the Unreleased Production Payment is brought to ARCO's attention by Purchaser or its affiliated party, but in either case ARCO's indemnity shall apply only to values in excess of $5,000.00. 3.4 NOTICE OF TITLE DEFECT. Purchaser shall notify ARCO in writing, as soon as reasonably practicable after Purchaser has knowledge thereof, and in any event on or before five (5) days prior to the Closing Date (the "Notification Deadline"), of any matter ("Title Defect") that would cause ARCO's title to any of the Properties or Valued Assets not to be Marketable Title, in each case together with a detailed explanation of (a) the nature of such Title Defect, (b) the Leasehold Interests or Valued Assets (or portions thereof) affected thereby and (c) Purchaser's proposed Defect Value (as hereinafter defined) for such Title Defect in a form similar to Exhibit 3.4. Any matters that would otherwise constitute Title Defects but which are not specifically raised in writing (with the detailed explanation as contemplated in the immediately preceding sentence) by Purchaser prior to the Notification Deadline shall conclusively be deemed waived by Purchaser. As used herein, the term "Defect Value" shall mean with respect to each Title Defect, the reduction in the "Allocated Value" of the affected Leasehold Interest or other Valued Asset as a result of such Title Defect, as determined pursuant to Sections 3.6 and 3.7. 3.5 REMEDIES FOR TITLE DEFECTS. (a) ARCO shall have the right, but not the obligation, to attempt to cure any Title Defect with respect to which it has received notice from Purchaser prior to the Notification Deadline. (b) With respect to any Title Defect for which ARCO receives the required notice from Purchaser on or before the Notification Deadline, ARCO and Purchaser shall attempt to agree, subject to the terms of the last sentence of this Section 3.5(b), upon a mutually acceptable remedy from among the following options: (i) For ARCO to indemnify Purchaser against all liability, loss, cost and expense resulting from such Title Defect, in which event the Purchase Price shall not be reduced and the Leasehold Interest or other Valued Asset subject to such Title Defect shall be sold to Purchaser hereunder (it being understood and agreed, however, that in no event shall ARCO's liability under any such indemnity exceed the Defect Value of the Title Purchase and Sale Agreement Page 8 9 Defect to which such indemnity relates or survive beyond the period provided in Section 17.13); (ii) To exclude the Leasehold Interest or other Valued Asset subject to the Title Defect from the sale hereunder, in which event the Purchase Price shall be reduced by the Allocated Value (as defined in Section 3.6) of such Leasehold Interest or other Valued Asset; or (iii) The Leasehold Interest or other Valued Asset subject to such Title Defect shall be sold to Purchaser hereunder and the Purchase Price shall be reduced by the Defect Value for such Title Defect. In the event ARCO and Purchaser are unable to agree upon one of the foregoing options on or before the Closing Date then, unless the Title Defect is waived in writing by Purchaser, either party shall have the right to submit the disputed item(s) for binding arbitration in accordance with Article 3.11. The Asset(s) subject to title defect resolution dispute shall be sold to Purchaser at Closing and no Purchase Price adjustment, indemnification by ARCO or reassignment to ARCO shall be made until warranted by agreement of the Parties or arbitration. THERE SHALL BE NO REDUCTION IN THE PURCHASE PRICE FOR TITLE DEFECTS PURSUANT TO THE TERMS OF THIS SECTION 3.5(b), AND ARCO SHALL NOT BE LIABLE FOR ANY INDEMNITY GRANTED PURSUANT TO THIS SECTION 3.5(b), UNLESS AND UNTIL, AND ONLY TO THE EXTENT THAT, THE AGGREGATE OF ALL SUCH AMOUNTS EXCEEDS $50,000.00 (c) To the extent that same are discovered by either party prior to the Notification Deadline, ARCO and Purchaser acknowledge and agree that the Purchase Price shall be increased (a "Title Increase") by an amount equal to the value allocated to the following: (i) any increase in ARCO's Net Revenue Interest shown on Exhibit A for a Property without a corresponding increase (in each case to the extent greater than 1% of the interest shown on Exhibit A) in ARCO's Working Interest above that shown on Exhibit A for such Property; or (ii) any decrease in ARCO's Working Interest below that shown on Exhibit A for any Property without a corresponding decrease (in each case to the extent greater than 1% of the interest shown on Exhibit A) in the Net Revenue Interest shown on Exhibit A for such Property, in each case with such values to be agreed upon by ARCO and Purchaser (taking into account the Allocated Value for such Property) or otherwise determined pursuant to the procedures set forth in Section 3.7. THERE SHALL BE NO INCREASE IN THE PURCHASE PRICE FOR TITLE INCREASES PURSUANT TO THE TERMS OF THIS SECTION 3.5 UNLESS AND UNTIL, AND ONLY TO THE EXTENT THAT, THE AGGREGATE OF ALL SUCH AMOUNTS EXCEEDS $50,000.00. (d) Notwithstanding anything to the contrary contained in this Agreement, (i) the existence of a Title Defect shall not result in Purchaser having any right to exclude any Leasehold Interest from the sale hereunder or to fail to perform its obligations at Closing, and (ii) there shall be no adjustment to the Purchase Price as a result of ARCO's title to any of the Assets other than the Leasehold Interests and other Valued Assets. 3.6 VALUE OF LEASEHOLD INTEREST OR TITLE DEFECT. As used herein, the term "Allocated Value" shall mean, with respect to any Valued Asset, Property, or any unit or well relating thereto, the amount set forth under the column entitled "Allocated Value" for such Property, unit or well on Exhibit 3.6 (which Exhibit 3.6 includes an Allocated Value for and list of all Leasehold Interests that have been identified prior to the date hereof as being subject to a preferential purchase right) or if no separate amount is set forth in Exhibit 3.6, the amount agreed upon by ARCO and Purchaser as the value of such Leasehold Interest, unit or well. If ARCO does not agree with Purchaser's proposed Defect Value or the parties are unable to agree upon whether a Title Defect exists, the Allocated Value of a Leasehold Interest or the value allocated to a Title Increase, in each case for purposes of Section 3.5, then the parties shall enter into good faith negotiations and shall attempt to agree on such matter, and any values to be agreed upon shall be based on the Allocated Value for the group of properties with which such Leasehold Interest, unit or well appears on Exhibit 3.6. 3.7 DETERMINATION OF VALUES BY CONSULTANT. Subject to ARCO's right to elect to indemnify Purchaser pursuant to Section 3.5(b)(i), if ARCO and Purchaser cannot reach agreement on the existence of a Title Defect, the Allocated Value of a Leasehold Interest, the Defect Value for a Title Defect or the value allocated to any Title Increases, in any such case within 10 days after the commencement of good faith negotiations pursuant to Section 3.6, at either party's option, upon notice to the other party, such Allocated Value, Defect Value or amount allocated to a Title Increase, as applicable, shall be determined by an independent petroleum reservoir consultant chosen by lot from among the following firms: DeGolyer & MacNaughton, Keplinger and Associates, Inc. and Gruy and Associates, Inc. Such consulting firm shall have the right to hire such additional neutral consultants and experts as it deems reasonably appropriate. The consultant chosen for the first applicable valuation hereunder shall serve for all Purchase and Sale Agreement Page 9 10 valuations hereunder; provided, however, that if at any time any consultant so chosen fails or refuses to perform hereunder, a new consultant shall be chosen in a similar manner from among the remaining firms. The cost of any consultant shall be borne one-half by ARCO and one-half by Purchaser. Each party shall present its position on the value in question to the consultant within five days after the consultant is requested to determine the value, and the consultant shall make a determination of the value involved as soon as practicable thereafter. The determination by the consultant shall be conclusive and binding on the parties, and shall be enforceable against any party in any court of competent jurisdiction. 3.8 NOTICES TO HOLDERS OF PREFERENTIAL PURCHASE RIGHTS. With respect to each party shown in ARCO's records as holding a preferential purchase right covering the Leasehold Interests (a preliminary list of such affected Leasehold Interests is set forth in Exhibit 3.6), ARCO shall send to the holder of such right a notice offering to sell to such holder, in accordance with the contractual provisions applicable to such right, those Leasehold Interests covered by such right on the terms hereof and for the same Allocated Value of such Leasehold Interests (as set forth on Exhibit 3.6), subject to adjustments in price in the same manner that the Purchase Price is adjusted pursuant to Article 2 of this Agreement. 3.9 EXERCISE OF PREFERENTIAL PURCHASE RIGHTS. If, prior to Closing, any holder of a preferential purchase right notifies ARCO that it intends to consummate the purchase of the Leasehold Interests to which its preferential purchase right applies, then those Leasehold Interests shall be excluded from the Assets to be conveyed to Purchaser under this Agreement, and the Purchase Price shall be reduced by the Allocated Value of such Leasehold Interests; provided, however, that if the holder of such preferential right fails to consummate the purchase of the Leasehold Interests covered by such right, then within 90 days following the Closing Date, ARCO may so notify Purchaser, and within 15 days after Purchaser's receipt of such notice from ARCO, ARCO shall sell to Purchaser, and Purchaser shall purchase from ARCO, for a price equal to the Allocated Value of such Leasehold Interests (as adjusted pursuant to the provisions of Section 2.2 above) and upon the other terms of this Agreement (to the extent applicable), the Leasehold Interests to which the preferential purchase right applied. All Leasehold Interests, other than those for which ARCO has received notice of the exercise of a preferential purchase right, subject to the other provisions of the Agreement, shall be sold to Purchaser at the Closing pursuant to the provisions of this Agreement. 3.10 RISK OF LOSS. Subject to the provisions of Section 9.7, no adjustment to the Purchase Price shall be made if, after the date hereof and prior to the Closing any part of the Assets shall be destroyed or harmed by fire or any other cause or shall be taken by condemnation or the exercise of eminent domain, but Purchaser shall be entitled to any applicable insurance proceeds (to the extent actually received by ARCO and not payable from a captive insurance carrier or subject to reimbursement or repayment by ARCO or its affiliates) or condemnation awards. 3.11 ARBITRATION PROCEDURE. If any matter is required by this Article 3 to be arbitrated, such arbitration shall be conducted as set forth in this Section 3.11. (a) The parties shall jointly select a mutually acceptable person as the sole arbitrator under this Agreement. If the parties are unable to agree upon the designation of a person as arbitrator, then either ARCO or Purchaser, or all of such parties, may in writing request the American Arbitration Association ("AAA") to appoint a qualified arbitrator. (b) Any arbitration hearing shall be held at a place in Houston, Texas acceptable to the arbitrator. (c) The arbitrator shall settle disputes regarding existence and value of Title Defects and ARCO's attempts to correct any Title Defects in accordance with the Texas General Arbitration Act (Chapter 171, Texas Civil Practice and Remedies Code) and the Commercial Arbitration Rules of the AAA, to the extent such rules do not conflict with the terms of such act and the terms hereof. Such arbitrator shall hear all arbitration matters arising under this Article 3. The decision of the arbitrator shall be binding upon the parties, and may be enforced in any court of competent jurisdiction. ARCO and Purchaser, respectively, shall bear their own legal fees and other costs incurred in presenting their respective cases. The charges and expenses of the arbitrator shall be shared equally by ARCO and Purchaser.

Subject to the provisions of Section 13.5(b), Purchaser shall indemnify ARCO for all liabilities which are assessed against ARCO for foreign, federal, state, local or Indian Tribal taxes (other than income taxes), together with penalties and interest thereon (provided such penalties and interest do not result from the negligence, late filing, fraud or acts of misfeasance or malfeasance of ARCO), to the extent such liabilities relate to the ownership or operation of the Assets from and after the Effective Date; provided, however, that such indemnity shall not apply to windfall profit, severance or production taxes on oil and gas production from the Assets on or after the Effective Date to the extent (but only to the extent) such taxes are included in the determination of the Adjusted Purchase Price, and provided further, however, that Purchaser shall be entitled to all refunds or rebates of windfall profit, severance or production taxes on oil and gas production from the Assets on or after the Effective Date that may be received by ARCO or Purchaser, except to the extent (but only to the extent) such refunds or rebates are included in the determination of the Adjusted Purchase Price.

Should Indemnitor fail to notify Claimant within such 30-day period, Indemnitor shall be deemed to have elected not to contest such liability. Should Indemnitor elect (or be deemed to have elected) not to contest such liability, Indemnitor shall pay the full amount due under Section 13.5(a) in respect of such liability to Claimant in cash within 30 days after Indemnitor elects (or is deemed to have elected) not to contest such liability.

The party in control may not adjust, compromise or settle taxes which are contested by or on behalf of the other party without the consent of the other party. With respect to any liability contested by Indemnitor under the terms of this Section 13.5(b), Indemnitor shall pay the full amount due under Section 13.5(a) in respect of such liability to Claimant in cash within 30 days after the liability is finally determined either by settlement or pursuant to the final unappealable judgment of a court of competent jurisdiction.

(Purchaser) FORM OF SURFACE LEASE AGREEMENT THIS LEASE AGREEMENT is made effective and entered into this 1st day of October, 1999, by and between ATLANTIC RICHFIELD COMPANY, a Delaware corporation, whose address is P.O. Box 1610, Midland, Texas 79702-1610, hereinafter called "Lessor", and FUTURE ACQUISITION 1995, LTD., a Texas limited partnership, whose address is 700 Louisiana, Suite 3700, Houston, Texas 77002, hereinafter referred to as "Lessee". LESSOR FOR AND IN CONSIDERATION of the rents, covenants and promises herein contained to be kept, performed and observed by Lessee, does hereby lease and demise to Lessee, and Lessee does hereby rent and accept from Lessor, that real property, referred to as the leased premises and more particularly described in EXHIBIT "A", attached hereto and made a part hereof, for the purposes of construction, installation, maintenance, inspection, operation, repair, change or removal of equipment and facilities useful or incidental to the operation of the office building and pipe yard located and established at 1907 East Old Highway 80, Longview, Texas 75605, together with the right of ingress and egress to and from the leased premises. TO HAVE AND TO HOLD the said leased premises, together with all rights, privileges, easements, appurtenances and immunities belonging to or in any way appertaining to said leased premises, including, but not limited to, concurrent use of, any and all easements, rights, title and privileges of Lessor now or hereafter existing in, to or under the leased premises. 1. This lease shall be for a term of ten (10) years, referred to as the lease term, commencing on October 1, 1999, and ending on September 30, 2009; subject, however, to earlier termination as hereinafter provided. 2. Lessee may extend this lease for additional periods of five (5) years by giving Lessor written notice of Lessee's intention to do so at least three (3) months prior to the expiration of the expiring term. Such notice will be sent to Lessor at the heretofore-stated address. This lease shall terminate and become null and void without further notice on the expiration of the term specified, and any holding over by Lessee after the expiration of said term shall not constitute a renewal hereof or give Lessee any rights hereunder in or to the leased premises. 3. The consideration for this lease is FIVE THOUSAND DOLLARS AND NO/100 ($5,000) cash in hand paid by Lessee to Lessor, receipt of which is hereby acknowledged, which said amount shall cover the rental hereunder for the period of October 1, 1999 to September 30, 2000. A like rental payment shall be due on October 1, 2000 and each subsequent anniversary date hereof during the term hereof. All rental payments accruing hereunder shall be payable to Lessor in Midland, Texas, by mailing same to Lessor at P.O. Box 1610, Midland, Texas 79702-1610. In the event any rental payment which may become due and payable hereunder is not duly paid when due, then in that event said Lessor may, at its option pursue such remedy or remedies as may be available to it for the collection of such amount or amounts due and owing to it, declare a forfeiture of the rights of the Lessee, in which event all rights of the Lessee hereunder shall cease and terminate, or both, and said Lessor shall have the right to immediate possession of said premises. In the event said Lessor shall elect to declare forfeiture hereof as aforesaid, said Lessee shall nevertheless be liable to said Lessor for the payment of rentals for the period of time this lease has remained in force pursuant hereto; and the rental for any fractional part of said yearly period during which said lease shall have been in force shall be deemed to be a full year's rental. If Lessee chooses to exercise its option to renew for additional consecutive five (5) year term or terms, the rental during each successive five-year term shall be twenty-five percent (25%) more than the rental paid during the immediately preceding five-year term. If Lessee elects to renew for an additional term, it shall do so by giving Lessor written notice as described above. Each subsequent payment for each five (5) year renewal shall be paid on or before the expiration date of the previous term. 4. In addition to the rental, Lessee shall pay and discharge all taxes, general and special assessments, fines or penalties incurred on or after October 1, 1999 and other charges of every description which during the term of this lease may be levied on or assessed against Lessor's and Lessee's interests in the leased premises and all improvements and other property thereon. 5. Any and all material, buildings, structures, equipment and all property of whatsoever kind or character placed or used on the subject property by the Lessee shall remain the property of Lessee and Lessee shall have the full and complete right at any time during the term of this lease, or within a reasonable time after the abandonment or termination hereof, not to exceed one year, 6 months, to go upon the subject property and remove said property therefrom. 6. Lessee may, at any time and from time to time, encumber the leasehold interest, by deed of trust, mortgage or other security instrument, without obtaining the consent of Lessor, but no such encumbrance shall constitute a lien on the fee title of Lessor, and the indebtedness secured thereby, shall at all times be and remain inferior and subordinate to all the conditions, covenants and obligations of this lease and to all of the rights of the Lessor hereunder. 7. In the event the leased premises or any part thereof shall be taken for public or quasi-public purposes by condemnation as a result of any action or proceeding in eminent domain, or shall be transferred in lieu of condemnation to any authority entitled to exercise the power of eminent domain, the interests of Lessor 209 and Lessee in the award or consideration for such transfer and the effect of the taking or transfer on this lease shall be as provided by this article. a) In the event the entire leased premises is taken or so transferred, this lease and all of the right, title and interest thereunder shall cease on the date title to such land so taken or transferred vests in the condemning authority, and the proceeds of such condemnation shall be divided so that Lessor shall receive all of such proceeds insofar and only insofar as they pertain to the title to the surface of the land, and any improvements placed thereon by Lessor, and Lessee shall receive all such proceeds insofar and only insofar as they pertain to the title to the improvements of Lessee existing on the leased premises. b) In the event of the taking or transfer of only a part of the leased premises leaving the remainder of the premises in such location, or in such form, shape or reduced size as to be not effectively and practicably usable in the opinion of Lessee for the purpose of operation thereon of Lessee's business, this lease and all right, title and interest thereunder shall cease on the date title to the land or the portion thereof so taken or transferred vests in the condemning authority. c) In the event of such taking of only a part of the leased premises leaving the remainder of the premises in such location and in such form, shape or size as to be used effectively and practicably in the opinion of Lessee for the purpose of operation thereon of Lessee's business, this lease shall terminate and end as to the portion of the premises so taken or transferred as of the date title to such portion vests in the condemning authority, but shall continue in full force and effect as to the portion of the leased premises not so taken or transferred. From and after such date, the rental required to be paid by Lessee to Lessor shall be reduced during the unexpired portion of this lease to that proportion of the annual fixed rental herein reserved which the value of the part of the leased premises not so taken bears to the value of the total of the leased premises, such values to be determined as of the date of the actual commencement of the physical taking of said premises when Lessee is disturbed in his possession as a result thereof but immediately before any actual taking. Lessee shall, however, continue to pay the full amount of percentage rent due hereunder. d) A voluntary conveyance by Lessor to a public utility, agency or authority under threat of a taking under the power of eminent domain in lieu of formal proceedings shall be deemed a taking within the meaning of this article. 9. Lessee shall use its best efforts to materially comply with all applicable laws, rules and regulations of any governmental authorities in connection with its use of the subject property. 10. Upon the termination of this lease, Lessee shall relinquish the leased premises from further use and occupancy and shall leave the surface of the leased premises in as near its original condition as is reasonably possible and shall remove any and all material, buildings structures, equipment and all property of whatsoever kind or character placed or used on the subject property by Lessee. 11. No assignment of this lease, either in whole or in part, shall be effective without first obtaining the prior written consent of Lessor. 12. Lessee shall indemnify and save Lessor harmless from all liability, damage, environmental claims, loss, cost and expense on account of any claim or claims asserted by any person or persons against Lessor because of bodily injury or death or damage to property resulting to such person or persons and arising out of Lessee's use and occupancy of the leased premises or the conduct and operation of any business of the Lessee thereon, and Lessee agrees, upon Lessor's request, to take over and defend, at Lessee's expense and without cost to Lessor, any and all suits or other proceedings instituted against Lessor by such person or persons to enforce any such claim or claims, and to pay and satisfy in full all sums that might be required to be paid to such person or persons, including all costs, expenses and reasonable attorney's fees, and expert and witness fees incurred in connection therewith. 13. Lessee shall permit Lessor or Lessor's agents, representatives or employees to enter on the leased premises for the purpose of inspection, to determine whether Lessee is in compliance with the terms of this lease, for purposes of maintaining, repairing or altering the premises, or for the purposes of showing the leased premises to prospective lessees, purchasers, mortgagees, or for the purpose of conducting tests, monitoring operations or remedial activities on or to the soil, surface water or groundwater or for any other lawful reason. 14. No waiver by Lessor of any default or breach of any covenant, condition or stipulation herein contained shall be treated as a waiver of any subsequent default or breach of the same or any other covenant, condition or stipulation hereof. 15. In the event Lessor shall sell or transfer the leased premises or any part thereof and as a part of such transaction shall assign its interest as Lessor in and to this lease, then from and after the effective date of such sale, assignment or transfer, Lessor shall have no further liability under this lease to Lessee except as to matters of liability which shall have accrued and are unsatisfied as of such date, it being intended that the covenants and obligations contained in this lease on the part of Lessor shall be binding on Lessor and its successors and assigns only during and in respect of their respective successive periods of ownership of the fee. 16. This agreement shall be binding upon and inure to the benefit of the parties hereto and their respective heirs, executors, administrators, legal representatives, successors and assigns where permitted by this agreement. 17. This agreement shall be construed under and in accordance with the laws of the State of Texas. 210 18. In case any one or more of the provisions contained in this agreement shall for any reason be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provision thereof and this agreement shall be construed as if such invalid, illegal or unenforceable provision had never been contained herein. 19. This agreement constitutes the sole and only agreement of the parties hereto and supersedes any prior understandings or written or oral agreements between the parties respecting the within subject matter. 20. No amendment, modification or alteration of the terms hereof shall be binding unless the same be in writing, dated subsequent to the date hereof and duly executed by the parties hereto. 21. The rights and remedies provided by this lease agreement are cumulative and the use of any one right or remedy by either party shall not preclude or waive its right to use any or all other remedies. Said rights and remedies are given in addition to any other rights the parties may have by law, statute, ordinance or otherwise. 22. In the event Lessor or Lessee breaches any of the terms of this agreement whereby the party not in default employs attorneys to protect or enforce its rights hereunder and prevails, then the defaulting party agrees to pay the other party reasonable attorney's fees so incurred by such other party. THIS LEASE HAS BEEN EXECUTED by the parties on the date and year first above written. LESSOR: LESSEE: ATLANTIC RICHFIELD COMPANY FUTURE ACQUISITION 1995, LTD.
