WHEREAS, Seller desires to sell to Buyer, and Buyer desires to purchase from Seller, all of the issued and outstanding capital stock of Greenhill Petroleum Corporation, a Delaware corporation (the "Company"), a wholly owned subsidiary of Seller, upon the terms and subject to the conditions set forth in this Agreement; NOW, THEREFORE, in consideration of the mutual covenants and agreements set forth in this Agreement, the parties hereto agree as follows: ARTICLE I. CERTAIN DEFINITIONS Section 1.1 Certain Defined Terms. Unless the context otherwise requires, the respective terms defined in APPENDIX A attached hereto and incorporated herein shall, when used herein, have the respective meanings therein specified, with each such definition to be equally applicable both to the singular and the plural forms of the term so defined. Section 1.2 References, Gender, Number. All references in this Agreement to an "Article," "Section," or "subsection" shall be to an Article, Section, or subsection of this Agreement, unless the context requires otherwise. Unless the context otherwise requires, the words "this Agreement," "hereof," "hereunder," "herein," "hereby," or words of similar import shall refer to this Agreement as a whole and not to a particular Article, Section, subsection, clause or other subdivision hereof. Whenever the context requires, the words used herein shall include the masculine, feminine and neuter gender, and the singular and the plural. ARTICLE II. SALE AND PURCHASE OF STOCK Section 2.1 Sale and Purchase. On and subject to the terms and conditions of this Agreement, Seller agrees to sell and convey to Buyer, and Buyer agrees to purchase from Seller, all of the issued and outstanding Company Shares. 9 ARTICLE III. PURCHASE PRICE AND PAYMENT Section 3.1 Purchase Price. The purchase price for the sale and conveyance of the Company Shares to Buyer is $270,500,000 (the "Purchase Price"), subject to adjustment in accordance with the terms of this Agreement. The "Adjusted Purchase Price" shall be the Purchase Price (i) as adjusted downward for any Environmental Defect or the exclusion of any Environmental Defect Property pursuant to Section 5.5, (ii) as adjusted downward for Title Defects, if any, in accordance with Section 6.2, (iii) as adjusted downward for excluded Title Defect Properties, if any, in accordance with Section 6.5, (iv) as adjusted for undisclosed gas imbalances, if any, pursuant to Section 3.5, (v) as adjusted downward by the amount of the Deposit, and (vi) as adjusted upward by an amount equal to interest on the Purchase Price, as adjusted in the manner provided in items (i) through (v) above, from the Effective Time until the Closing Date at the Agreed Rate. Section 3.2 Payment. Contemporaneously with the execution of this Agreement, Buyer and Seller shall enter into an escrow agreement (the "Escrow Agreement") pursuant to which Buyer shall deposit with the escrow agent thereunder $15,000,000 (the "Escrow Agent") as a deposit hereunder (the "Deposit"). The "Closing Payment" shall be an amount equal to (i) the Adjusted Purchase Price, (ii) plus the Net Intercompany Payables as of the Closing Date, if any, and (iii) less the Net Intercompany Receivables as of the Closing Date, if any. The net amounts in clauses (ii) and (iii) of the preceding sentence shall be based on the Intercompany Statement delivered pursuant to Section 3.4(a) below. At the Closing, Buyer shall wire transfer the Closing Payment in immediately available funds to the account specified by Seller to Buyer on or prior to the Business Day immediately preceding the Closing Date. Also at the Closing, and pursuant to the Escrow Agreement, the Escrow Agent shall wire transfer the Deposit, together with all interest and other amounts earned thereon, in immediately available funds to the foregoing account specified by Seller. Section 3.3 Intercompany and Parent Obligations. (a) At the Effective Time, the Company had certain receivables owed to the Company by the Seller or a Seller Related Company (the "Intercompany Receivables") and certain payables owed by the Company to the Seller or a Seller Related Company (the "Intercompany Payables") which are reflected in the Financial Statements. Subject to and without limiting Section 3.3(b), the Intercompany Receivables and Intercompany Payables which are reflected in the Financial Statements as of the Effective Time are fixed and binding on Seller, the Seller Related Companies, Buyer and the Company and no changes or adjustments shall be made thereto pursuant to Section 3.4, it being agreed that reviews and adjustments pursuant to Section 3.4 shall be limited to changes in the Intercompany Payables and Intercompany Receivables between the Effective Time and the Closing Date. Without limiting the generality of the foregoing and notwithstanding the accounting treatment accorded such items for GAAP, capital contributions and loans made by the Seller or any Seller Related Company to the Company (and any amount owing by the Company to Seller or any Seller Related Company pursuant to the agreements or transactions referenced in SCHEDULE 4.1(O) or SCHEDULE 8.1) between the Effective Time and the Closing Date shall result in 2 10 an Intercompany Payable; and dividends and distributions made by the Company to the Seller or any Seller Related Company between the Effective Time and the Closing Date shall result in an Intercompany Receivable. (b) At the Effective Time, the Seller Parent Company had contingent liability under certain guaranties, letters of credit and bonds in the respective amounts under the respective agreements or instruments described in SCHEDULE 3.3 (collectively the "Parent Obligations"). On or before the Closing Date, the Buyer shall provide or cause to be provided substitute guaranties, letters of credit, bonds or other assurances to the beneficiaries of the Parent Obligations and will use its best efforts to cause the Parent Obligations (and all liability of the Seller Parent Company in connection therewith) to be fully and unconditionally released on the Closing Date, in form and substance satisfactory to the Seller Parent Company. If the Seller Parent Company makes any payment, advance or reimbursement under the Parent Obligations after the Effective Time and prior to receiving the above required release of the Parent Obligations, the amounts so paid, advanced or reimbursed shall be considered Intercompany Payables and shall increase the amount of Intercompany Payables. Following the Effective Time until the Closing Date, changes may also occur in the amounts of Intercompany Payables and Intercompany Receivables as a result of advances for working capital or repayments of Intercompany Receivables after the Effective Time. Section 3.4 Intercompany Adjustment Amount. (a) As of the Closing Date, a net amount shall be determined by offsetting all Intercompany Payables and Intercompany Receivables. If such offsetting results in net Intercompany Payables, then such net payable amount shall be the "Net Intercompany Payables". If such offsetting results in net Intercompany Receivables, then such net receivable amount shall be the "Net Intercompany Receivables". The Seller shall deliver to Buyer on or prior to the third Business Day immediately preceding the Closing Date a statement (the "Intercompany Statement") setting forth the Seller's preliminary determination of the Net Intercompany Payables or the Net Intercompany Receivables, as the case may be. After the Closing, Seller and Buyer shall each have the right, subject to the limitations in Section 3.3(a), to review the Intercompany Statement and such preliminary determination of the Net Intercompany Payables or Net Intercompany Receivables. Buyer will give representatives of Seller reasonable access to the Company's books and records for purposes of reviewing the Intercompany Statement and resolving any of Buyer's or Seller's disagreements with or proposed changes to the Intercompany Statement. (b) The Intercompany Statement shall become final and binding on Seller and Buyer ninety (90) days following the Closing Date, except to the extent that prior to the expiration of such ninety (90) day period Buyer or Seller shall deliver to the other notice, as hereinafter required, of its disagreement with and changes to the Intercompany Statement. Any disagreements with or changes to the Intercompany Statement not included in such notices shall be waived. Such notices shall be in writing and set forth all of Buyer's or Seller's, as the case may be, disagreements with respect to any portion of the Intercompany Statement, together with its proposed changes thereto, and shall include an explanation in reasonable detail of, and such supporting documentation 3 11 as is reasonably necessary to support, such changes. If Buyer or Seller has timely delivered one or more such notices to the other, then, upon written agreement between Buyer and Seller resolving all disagreements and changes of Buyer and Seller set forth in such notices, the Intercompany Statement (including any revisions thereto as are so agreed) will become final and binding upon Buyer and Seller. If the Intercompany Statement has not become final and binding by the one hundred twentieth (120th) day following the Closing Date, then Buyer or Seller may submit any unresolved disagreements of Buyer or Seller set forth in the aforesaid notices to Price Waterhouse L.L.P., Houston, Texas for final and binding determination, subject to the limitations of Section 3.3(a). Upon resolution of such unresolved disagreements of Buyer and Seller, the Intercompany Statement (including any revisions thereto as are so resolved or agreed), shall be conclusive, final and binding upon Buyer and Seller. If such final amount of Net Intercompany Payables or Net Intercompany Receivables is more or less than the amount therefor in the Intercompany Statement on which the Closing Payment paid at Closing was based, the Closing Payment shall be redetermined under Sections 3.2 and 3.4(a) using such final amount of Net Intercompany Payables or Net Intercompany Receivables. If such redetermination under Sections 3.2 and 3.4(a) results in a reduction in the Closing Payment, Seller shall pay Buyer the amount of such reduction. If such redetermination results in an increase in the Closing Payment, Buyer shall pay Seller the amount of such increase. Within three (3) Business Days after the Intercompany Statement (as so resolved or agreed) becomes final and binding, Seller or Buyer, as appropriate, shall pay to the other party the amount of such increase or reduction, if any, together with interest thereon at the Agreed Rate from (i) the Closing Date until paid in the event Buyer is making a payment to Seller or (ii) the Effective Time until paid in the event Seller is making a payment to Buyer. Once the Intercompany Statement becomes final and binding as aforesaid and any required adjustment payment is made pursuant to the foregoing, all Intercompany Payables and Intercompany Receivables as of the Closing Date shall be deemed fully paid, discharged and released. Section 3.5 Gas Imbalance Adjustments. The Purchase Price shall be: (a) reduced by the product obtained by multiplying the aggregate amount of Unscheduled (Negative) Imbalances by $2.10 per MMBtu; and (b) increased by the product obtained by multiplying the aggregate amount of Unscheduled (Positive) Imbalances by $2.10 per MMBtu.

Without limiting or waiving Seller's right to then or thereafter dispute the existence of an Environmental Defect or the alleged Environmental Defect Amount, if Buyer timely notifies Seller in writing of an Environmental Defect as required by Section 5.5(a), Seller, at its option, shall elect, at or prior to the Closing, one of the following options with respect to the Assets affected by the alleged Environmental Defect and, at Seller's option, any other Assets which form part of any field or other economic operating unit which includes such affected Assets (collectively, the "Environmental Defect Property"): (i) except for Environmental Defect Properties which constitute unitized areas or offshore blocks, exclude such Environmental Defect Property from the Assets by causing the Company to convey the same (together with Incidental Rights and assets attributable or appurtenant thereto in the manner provided in Section 6.5 for excluded Title Defect Properties, but only to the extent such Incidental Rights and assets are practicably severable from the Assets without adversely impacting in any material respect the value or operations of the remaining Assets; provided, however, if such Incidental Rights and assets are not so practicably severable from the Assets, at or prior to the Closing or such later date as is provided in Section 6.6, Seller or Buyer, as appropriate, shall cause the Company to execute and deliver to the transferee of such Environmental Defect Property designated by Seller a perpetual use agreement on commercially reasonable terms which grants to such transferee the practical benefits such transferee would have received from such Incidental Rights and assets had they been so conveyed to such transferee) to a transferee designated by Seller at or prior to Closing or such later date as is provided in Section 6.6 and reduce the Purchase Price by the portion of the Purchase Price allocated to such Environmental Defect Property in the Property Schedule; (ii) leave such Environmental Defect Property in the Assets and assume responsibility for the Remediation of such Environmental Defect; provided that, all 18 26 costs for Remediation shall first be borne by Buyer to the extent Seller elects to apply any of the Environmental Defect Deductible to such costs; or (iii) leave such Environmental Defect Property in the Assets and reduce the Purchase Price by the Environmental Defect Amount with respect to such Environmental Defect (taking into account any application of the Environmental Defect Deductible which Seller elects to make with respect thereto). If Seller elects the option set forth in clause (iii) above, Buyer shall be deemed to have assumed responsibility for Remediation of such Environmental Defect and such Environmental Defect shall be deemed to constitute a Company Liability. If Seller elects the option set forth in clause (ii) above, Seller shall use commercially reasonable efforts to implement such Remediation in a manner which is consistent with the requirements of Environmental Laws and the provisions of any applicable lease, and Seller shall have access to the Environmental Defect Property after the Closing Date to implement and complete such Remediation in accordance with this section and an Access Agreement in substantially the form attached hereto as EXHIBIT 5.5(B) (the "Access Agreement"). Seller will be deemed to have adequately completed the Remediation required in the immediately preceding sentence (a) (i) upon receipt of a certificate or approval from the applicable state or federal authority that the Remediation has been implemented to the extent necessary to comply with existing regulatory requirements or (ii) upon receipt of a certificate from a licensed professional engineer if the approval or certification specified in (i) cannot be obtained because provision for such approval or certification is not provided under federal or state law and (b) to the extent express approval from the lessor is required under any applicable lease, upon receipt of such approval. For purposes of the option set forth in clause (i) above, the portion of the Purchase Price allocated to an Environmental Defect Property which includes one or more Subject Interests shall be the portion of the Purchase Price allocated to such Subject Interests in the Property Schedule, as adjusted pursuant to Section 6.2(b); provided that, if such Environmental Defect Property does not include any Subject Interest, then the portion of the Purchase Price allocated to such Environmental Defect Property shall be the fair market value of such Environmental Defect Property at the Effective Time, however, such portion of the Purchase Price shall never be more than the relative value (based on the Purchase Price allocations in the Property Schedule) of such Environmental Defect Property as a component of the Subject Interests with respect to which such Environmental Defect Property is used. A reduction in the Purchase Price pursuant to the option set forth in clause (i) above on account of an Environmental Defect Property which does not include any Subject Interests shall be applied, without duplication, to proportionately reduce the portion of the Purchase Price allocated in the Property Schedule to the Subject Interests in connection with which such Environmental Defect Property is used. If such Environmental Defect Property is not used in connection with any Subject Interests, no portion of the Purchase Price will be allocated thereto. (c) Environmental Defect Amount. If Seller elects the option set forth in Section 5.5(b)(iii) with respect to one or more Environmental Defects, then as Buyer's sole and exclusive remedy with respect to such Environmental Defects, Buyer shall be entitled to reduce the Purchase Price by the amount (the "Environmental Defect Amount"), if any, by which the 19 27 Remediation Amount with respect to the Environmental Conditions giving rise to such Environmental Defects exceeds that part, if any, of $500,000 (the "Environmental Defect Deductible") which Seller elects to apply as an offset or deduction against such Remediation Amount. Seller may also apply any part of the Environmental Defect Deductible to the cost of any Remediation undertaken by Seller pursuant to the option set forth in Section 5.5(b)(ii) and to reduce any post-Closing indemnity obligation of Seller with respect to Seller Environmental Obligations under Article XIII. Any Remediation costs to which Seller elects to apply the Environmental Defect Deductible shall be borne by the Buyer. Seller shall have the right from time to time upon written notice to Buyer to reallocate and change its application of the Environmental Defect Deductible, except to the extent of Remediation costs already incurred or contracted for by Buyer based on Seller's previous application thereof. It is expressly understood and agreed that the Environmental Defect Deductible represents an aggregate deductible for Environmental Defects which may be apportioned as provided in this Section 5.5(c) rather than as a separate deductible for each individual Environmental Claim. (d) Waiver by Buyer. If, prior to the expiration of the Environmental Examination Period, the Buyer has knowledge of an Environmental Defect and does not notify Seller in writing of the existence thereof on or before the expiration of the Environmental Examination Period (including, without limitation, any Environmental Defect noted or described in any oral or written report prepared by the Environmental Consultant), the Buyer shall be deemed to have waived such Environmental Defect and such Environmental Defect shall be deemed to constitute a Company Liability. In addition, all conditions and matters of which Buyer has knowledge prior to the expiration of the Environmental Examination Period and which would have constituted Environmental Defects but for the $25,000 threshold limitation set forth in the definition of Environmental Defect shall be deemed to constitute Company Liabilities. (e) Right of Contribution and Reimbursement. With respect to any Environmental Defect as to which Seller elects to assume responsibility pursuant to Section 5.5(b)(ii) and any other Environmental Liability for which any Buyer Indemnified Party is entitled to indemnification from Seller pursuant to Article XIII, if any Buyer Indemnified Party has a claim for or right of contribution, reimbursement, indemnity or other similar actions from or against any third Person (including any Affiliate of Buyer, other than the Company) with respect thereto, the Buyer Indemnified Party having such claim or right shall assign such claim or right to Seller to the extent assignable and shall assist Seller, at Seller's sole cost and expense, in pursuing and enforcing same. Furthermore, in consideration for the agreement of Seller to indemnify and defend the Buyer Indemnified Parties from and against certain Environmental Matters pursuant to Article XIII, effective upon Closing, Buyer for itself and the Company hereby releases, acquits and forever discharges the Seller and the Seller Indemnified Parties from any and all claims, demands or causes of action which Buyer or the Company may have against Seller or any Seller Indemnified Party with respect to any and all Environmental Matters (including, but not limited to, any right of contribution or reimbursement provided under Environmental Laws or other Laws) for which Seller has not agreed to indemnify any Buyer Indemnified Party or assume responsibility for Remediation and 20 28 associated liabilities pursuant to this Agreement. At Seller's request, the Company shall provide Seller with a written confirmation of the foregoing release at or after Closing. ARTICLE VI. TITLE ADJUSTMENTS Section 6.1 No Title Warranty or Representation. WITHOUT LIMITING BUYER'S RIGHT TO ADJUST THE PURCHASE PRICE BY OPERATION OF SECTION 6.2, SELLER MAKES NO WARRANTY OR REPRESENTATION, EXPRESS, IMPLIED, STATUTORY OR OTHERWISE, WITH RESPECT TO THE COMPANY'S TITLE TO ANY OF THE ASSETS AND BUYER HEREBY ACKNOWLEDGES AND AGREES THAT BUYER'S SOLE REMEDY FOR ANY DEFECT OF TITLE, INCLUDING ANY TITLE DEFECT, WITH RESPECT TO ANY OF THE ASSETS SHALL BE PURSUANT TO THE PROCEDURES SET FORTH IN THIS ARTICLE VI, WHICH REMEDIES SHALL CEASE, AND BE DEEMED TO BE FINALLY AND CONCLUSIVELY SATISFIED, IN ALL RESPECTS, UPON THE CLOSING. Section 6.2 Buyer's Title Review. (a) Buyer's Assertion of Title Defects. On or prior to March 31, 1997 (the "Title Examination Period"), Buyer shall furnish Seller written notice meeting the requirements of this Section 6.2(a) (the "Title Defect Notice") setting forth any matters which, in Buyer's reasonable opinion, constitute Title Defects and which Buyer intends to assert as a Title Defect with respect to any portion of a Property Subdivision pursuant to this Article VI. For all purposes of this Agreement, Buyer shall be deemed to have waived any Title Defect which Buyer fails to assert as a Title Defect by a Title Defect Notice given to Seller on or before the expiration of the Title Examination Period. To be effective, Buyer's Title Defect Notice of a Title Defect must include (i) a brief description of the matter constituting the asserted Title Defect, (ii) the claimed Title Defect Amount attributable thereto, and (iii) supporting documents reasonably necessary for Seller (as well as any title attorney or examiner hired by Seller) to verify the existence of such asserted Title Defect. To give Seller an opportunity to commence reviewing and curing Title Defects, on or before the end of each calendar week during the Title Examination Period, Buyer agrees to give Seller written notice of all Title Defects discovered by Buyer during the calendar week preceding the calendar week then ending, which may be preliminary in nature and supplemented prior to the end of the Title Examination Period. Buyer shall also promptly furnish Seller with written notice of any Seller Title Credit which is discovered by any of Buyer's employees or representatives while conducting Buyer's title review, due diligence or investigation with respect to the Subject Interests and Property Subdivisions. (b) Purchase Price Allocations. A portion of the Purchase Price has been allocated to the various Subject Interests in Property Subdivisions in the manner and in accordance with the respective values set forth in the Property Schedule. If any adjustment is made to the Purchase Price pursuant to this Section 6.2 or Section 5.5, a corresponding adjustment shall be made to the portion of the Purchase Price allocated to the affected Property Subdivision in the Property Schedule. 21 29 (c) Seller's Opportunity to Cure. (i) Seller shall have until two (2) days prior to the Closing Date, at its cost and expense, if it so elects but without obligation, to cure all or a portion of such asserted Title Defects. Any asserted Title Defects which are waived by Buyer within such time shall be deemed "Permitted Encumbrances" hereunder. Subject to Sections 6.2(c)(ii) and 6.2(c)(iii) and Seller's continuing right to dispute the existence of a Title Defect and/or the Title Defect Amount asserted with respect thereto, if Seller within such time fails to cure any Title Defect of which Buyer has given timely written notice as required above, and Buyer has not and does not waive same on or before the day immediately preceding the Closing Date, the Property Subdivision affected by such uncured and unwaived Title Defect shall be a "Title Defect Property". (ii) If Buyer furnishes to Seller timely Title Defect Notice(s) of one or more Title Defects and the same are not waived or cured as provided in Section 6.2(c)(i), Seller may elect to delay the Closing for a period of up to thirty (30) calendar days to afford Seller the opportunity, if it so elects, to attempt to cure any of the properly asserted Title Defects prior to the Closing. Notwithstanding Section 3.1(vi) to the contrary, if Seller elects to delay the Closing pursuant to this Section 6.2(c)(ii) to afford it the opportunity, if it so elects, to attempt to cure any Title Defects, Buyer shall not be obligated to pay any interest on the Purchase Price from the original Closing Date until the extended Closing Date. Subject to Section 6.2(c)(iii) and Seller's continuing right to dispute the existence of a Title Defect and/or the Title Defect Amount asserted with respect thereto, if Seller within such time period fails or refuses to cure any Title Defect of which Buyer has given a timely Title Defect Notice and Buyer has not waived and does not waive the same before the delayed Closing, the Property Subdivision affected by such uncured and unwaived Title Defect shall be a "Title Defect Property." (iii) If Buyer furnishes to Seller timely Title Defect Notice(s) of one or more Title Defects and the same are not waived or cured as provided in Section 6.2(c)(i) or Section 6.2(c)(ii), as applicable, Seller may elect to close the transactions contemplated hereby and retain the right to cure any of such Title Defects after Closing (whether or not Seller elects to delay Closing pursuant to Section 6.2(c)(ii) above). In such event, but subject to Seller's continuing right to dispute the existence of a Title Defect and/or the Title Defect Amount asserted with respect thereto, the Purchase Price shall be subject to reduction pursuant to Section 6.2(d) taking into account all Title Defect Amounts attributable to the Title Defect Properties affected by the Title Defects which Seller may elect to cure after Closing. The Title Defect Properties affected by the Title Defects which Seller may elect to cure after Closing shall not be excluded from the Assets pursuant to Section 6.5. Seller shall have one hundred twenty (120) calendar days after the 22 30 Closing Date (as may be delayed pursuant to Section 6.2(c)(iii) above) in which to attempt to cure any such Title Defects and to increase or restore any Seller Title Credits. If Seller cures any such Title Defect, then Buyer shall promptly pay Seller the Title Defect Amount with respect to the Title Defect that is so cured, but not exceeding the aggregate amount of the reductions in the Purchase Price which Buyer received as a result of any Title Defects, together with interest on the amount due Seller from the Closing Date through and including the date of payment at the Agreed Rate. Furthermore, the Title Defect Deductible shall be restored to the extent any portion of the Title Defect Deductible was applied as a credit against the Title Defect Amount attributable to such cured Title Defect. If a positive balance exists in the Available Deductible Amount after any restorations or increases thereof pursuant to the foregoing, and Seller has suffered a reduction in the Purchase Price as a result of any one or more uncured Title Defects, Buyer shall pay to Seller an amount (together with interest thereon from the Closing Date through and including the date of payment at the Agreed Rate) equal to the lesser of (i) the amount by which the Purchase Price was reduced as a result of such uncured Title Defects and (ii) the then existing balance of the Available Deductible Amount. (d) Buyer's Title Adjustments. Subject to Section 6.5, as Buyer's sole and exclusive remedy with respect to Title Defects, Buyer shall be entitled to reduce the Purchase Price by the amount, if any, by which the aggregate amount of Title Defect Amounts with respect to all Title Defect Properties exceeds the sum (the "Available Deductible Amount") of $1,300,000 (the "Title Defect Deductible") plus the aggregate amount of Seller Title Credits with respect to all Property Subdivisions. "Title Defect Amount" shall mean, with respect to a Title Defect Property, the amount by which the value of such Title Defect Property is impaired as a result of the existence of one or more uncured and unwaived Title Defects, which amount shall be determined as follows and subject to the following conditions: (1) If the Title Defect results from the Company having a lesser Net Revenue Interest in such Title Defect Property than the Net Revenue Interest specified therefor in the Property Schedule, the Title Defect Amount shall be equal to the product obtained by multiplying the portion of the Purchase Price allocated to such Title Defect Property in the Property Schedule by a fraction, the numerator of which is the reduction in the Net Revenue Interest and the denominator of which is the Net Revenue Interest specified for such Title Defect Property in the Property Schedule. (2) If the Title Defect results from the Company having a greater Working Interest in a Title Defect Property than the Working Interest specified therefor in the Property Schedule, the Title Defect Amount shall be equal to the present value (discounted at 10% compounded annually) of the increase in the costs and expenses forecasted in the Reserve Reports with respect to such Title Defect 23 31 Property for the period from and after the Effective Time which is attributable to such increase in the Company's Working Interest. (3) If the Title Defect results from the existence of a lien, the Title Defect Amount shall be an amount sufficient to discharge such lien. (4) If the Title Defect results from any matter not described in paragraphs (1), (2) or (3) above, the Title Defect Amount shall be an amount equal to the difference between the value of the Title Defect Property affected by such Title Defect with such Title Defect and the value of such Title Defect Property without such Title Defect (taking into account the portion of the Purchase Price allocated in the Property Schedule to such Title Defect Property); provided, that if such Title Defect is reasonably susceptible of being cured, the Title Defect Amount shall be the reasonable cost and expense of curing such Title Defect, if less. (5) If a Title Defect is not effective or does not affect a Title Defect Property throughout the entire productive life of such Title Defect Property, such fact shall be taken into account in determining the Title Defect Amount. (6) The Title Defect Amount with respect to a Title Defect Property shall be determined without duplication of any costs or losses included in another Title Defect Amount hereunder. For example, but without limitation, if a lien affects more than one Title Defect Property or the curative work with respect to one Title Defect results (or is reasonably expected to result) in the curing of any other Title Defect affecting the same or another Title Defect Property, the amount necessary to discharge such lien or the cost and expense of such curative work shall only be included in the Title Defect Amount for one Title Defect Property (or allocated among one or more Title Defect Properties so affected, as may be specified by Buyer) and only once in such Title Defect Amount. (7) If a Title Defect affects only a portion of a Property Subdivision (as contrasted with an undivided interest in the entirety of such Property Subdivision) and a portion of the Purchase Price has not been allocated specifically to such portion of a Property Subdivision in the Property Schedule, then for purposes of computing the Title Defect Amount, the portion of the Purchase Price allocated to such Property Subdivision shall be further allocated among the portions of such Property Subdivision in the proportion that the net acreage (or net acre feet, as appropriate) of such Property Subdivision affected by such Title Defect bears to the net acreage (or net acre feet, as appropriate) in the entire Property Subdivision. In the event such Property Subdivision is subject to a unitization agreement, the foregoing allocation shall be made in a manner which is consistent with the allocation of production or productive acreage in such unitization agreement. 24 32 (8) The Title Defect Amount attributable to a Title Defect Property or any portion thereof shall not exceed the portion of the Purchase Price allocated to such Title Defect Property or such portion in Section 6.2(b) and paragraph (7) above. For example, but without limitation, if the Company does not own fifty percent (50%) of the Net Revenue Interest specified in the Property Schedule for a Title Defect Property and such unowned fifty percent (50%) interest is also burdened by a lien, the Title Defect Amount for such Title Defect Property shall not exceed the portion of the Purchase Price allocable to such fifty percent (50%) interest notwithstanding that it may be affected by multiple Title Defects. (9) No Title Defect Amount shall be allowed on account of and to the extent that an increase in the Company's Working Interest in a Property Subdivision has the effect of proportionately increasing the Company's Net Revenue Interest in such Property Subdivision. (10) With respect to any Subject Interest in a Property Subdivision in which Buyer or an Affiliate of Buyer likewise owned an undivided interest at the Effective Time, no Title Defect Amount shall be allowed on account of a Title Defect affecting such Subject Interest that also affected Buyer's or such Affiliate's interest in such Property Subdivision in the same manner at the Effective Time. (11) Notwithstanding the foregoing, if the Title Defect Amount determined pursuant to the foregoing with respect to a Title Defect Property is $10,000 or less, then the Title Defect Amount with respect to such Title Defect Property shall be deemed zero; provided, however, that the aggregate amount of Title Defect Amounts with respect to Title Defect Properties of less than $10,000 which are deemed to be zero by reason of this paragraph (11) shall not exceed $250,000. Section 6.3 Determination of Title Defects. A portion of a Property Subdivision shall be deemed to have a "Title Defect" if any one or more of the following statements is untrue with respect to such portion of a Property Subdivision as of the Effective Time and/or as of the Closing Date: (a) The Company has Defensible Title thereto. (b) All rentals, Pugh clause payments, shut-in gas payments and other similar payments (other than royalties, overriding royalties and other similar payments on production) due with respect to such portion of a Property Subdivision have been properly and timely paid. (c) Except for the failure to timely and/or fully pay any royalties, overriding royalties or similar payments on production, the Seller is not in default under the material terms of any leases, farmout agreements or other contracts or agreements respecting such portion of a Property Subdivision which could (1) prevent the Company from receiving the proceeds of 25 33 production attributable to the Company's interest therein, or (2) result in cancellation of the Company's interest therein. Notwithstanding any other provision in this Agreement to the contrary, the following matters shall not be asserted as, and shall not constitute Title Defects: (i) defects in the early chain of the title consisting of the mere failure to recite marital status in a document or omissions of successions of heirship proceedings, unless Buyer provides affirmative evidence that such failure or omission results in another Person's superior claim of title to the relevant Subject Interest or portion thereof, (ii) defects arising out of lack of survey, (iii) defects arising out of lack of corporate authorization, unless Buyer provides affirmative evidence that such lack of authorization results in another Person's superior claim of title to the relevant Subject Interest or portion thereof, (iv) the failure to obtain or absence of any federal patent or conveyance with respect to any lands over which any state has claimed ownership and which have been covered by a state lease for more than ten years, and (v) defects that have been cured by possession under the applicable statutes of limitations or statutes for prescription. Furthermore, in determining the existence of a Title Defect, due consideration shall be given to the length of time hydrocarbons have been produced from the affected property without any adverse claim even though such period may be less than the period of possession or use required under applicable limitations or prescription statutes. Section 6.4 Seller Title Credit. A "Seller Title Credit" shall mean, with respect to a Property Subdivision, the amount by which the value of such Property Subdivision is enhanced by virtue of (a) the Company having a greater Net Revenue Interest in such Property Subdivision than the Net Revenue specified therefor in the Property Schedule, (b) the Company having a lesser Working Interest in such Property Subdivision than the Working Interest specified therefor in the Property Schedule, or (c) such Property Subdivision being subject to lesser lien indebtedness than expressly disclosed in any Schedule hereto, which amount shall be determined as follows: (1) If the Seller Title Credit results from the Company having a greater Net Revenue Interest in such Property Subdivision than the Net Revenue Interest specified therefor in the Property Schedule, the Seller Title Credit shall be equal to the product obtained by multiplying the portion of the Purchase Price allocated to such Property Subdivision in the Property Schedule by a fraction, the numerator of which is the increase in the Net Revenue Interest and the denominator of which is the Net Revenue Interest specified for such Property Subdivision in the Property Schedule. (2) If the Seller Title Credit results from the Company having a lesser Working Interest in a Property Subdivision than the Working Interest specified therefor in the Property Schedule, the Seller Title Credit shall be equal to the present value (discounted at 10% compounded annually) of the decrease in the costs and expenses forecasted in the Reserve Report with respect to such Property Subdivision for the period from and after the Effective Time which is attributable to such decrease in the Company's Working Interest. 26 34 (3) If the Seller Title Credit results from a Property Subdivision being subject to lesser lien indebtedness, the Seller Title Credit shall be equal to the amount of the Company's proportionate share of the reduction in such lien indebtedness; provided that, if lien indebtedness affects more than one Property Subdivision, the Seller Title Credits with respect to such Property Subdivisions shall be determined without duplication (e.g., credit shall not be given twice to the same reduction in indebtedness);and provided further, no Seller Title Credit shall be allowed to the extent such lien indebtedness is paid by the Company after the Report Date and is not reimbursed by Seller. (4) In determining the amount of Seller Title Credits, the principles and methodology set forth in paragraphs (5), (6) and (7) of Section 6.2(d) shall be applied, mutatis mutandis. (5) No Seller Title Credit shall be allowed on account of and to the extent that a decrease in the Company's Working Interest in a Property Subdivision has the effect of proportionately decreasing the Company's Net Revenue Interest in such Property Subdivision. (6) Notwithstanding the foregoing, if the Seller Title Credit determined pursuant to the foregoing with respect to a Property Subdivision is $10,000 or less, the Seller Title Credit with respect to such Property Subdivision shall be deemed zero; provided, however, that the aggregate amount of Seller Title Credits with respect to Property Subdivisions of less than $10,000 which are deemed to be zero by reason of this paragraph (6) shall not exceed $250,000. The Title Defect Deductible shall be restored to the extent that any portion thereof is applied as a credit against a Title Defect Amount attributable to a Title Defect which is subsequently cured by Seller or determined not to constitute a Title Defect. Section 6.5 Exclusion of Defect Properties. On or before the Closing Date, Seller may elect to exclude any Title Defect Property from the Assets by causing the Company to convey the same to a transferee designated by Seller so long as the Purchase Price is reduced by the portion of the Purchase Price allocated to such Title Defect Property in the Property Schedule. Upon such election by Seller, said Title Defect Property, together with a pro rata share of all Incidental Rights, oil, gas and other hydrocarbons and other assets attributable or appurtenant thereto (but only to the extent such Incidental Rights, oil, gas and other hydrocarbons and other assets are practicably severable from the Assets without adversely impacting in any material respect the value or operations of the remaining Assets; provided, however, if such Incidental Rights, oil, gas and other hydrocarbons and other assets are not so practicably severable from the Assets, upon such election by Seller, Seller or Buyer, as appropriate, shall cause the Company to execute and deliver to the transferee of said Title Defect Property designated by Seller a perpetual use agreement on commercially reasonable terms which grants to such transferee the practical benefits such transferee 27 35 would have received from such Incidental Rights, oil, gas and other hydrocarbons and other assets had they been so conveyed to such transferee), shall be conveyed by the Company to such designated transferee and excluded from the Assets. Section 6.6 Deferred Claims and Disputes. In the event that Buyer and Seller have not agreed upon (i) the existence of one or more Title Defects or Seller Title Credits or one or more adjustments, credits or offsets claimed by Buyer or Seller pursuant to and in accordance with the requirements of this Article VI or (ii) the existence of one or more Environmental Defects, any Remediation, Remediation Amount or plan therefor, or one or more adjustments, credits or offsets claimed by Buyer or Seller pursuant to Section 5.5, any such dispute or claim (a "Deferred Adjustment Claim") shall be settled pursuant to this Section 6.6 and, except as provided in Sections 9.1(f), 9.2(f) and 9.4, shall not prevent or delay Closing. In no event shall any Title Defect Amount, Environmental Defect Amount or Remediation Amount asserted by Buyer, or any Seller Title Credit asserted by Seller, as a Deferred Adjustment Claim exceed the amount asserted by Buyer or Seller therefor prior to the end of the Title Examination Period in accordance with Section 6.2 or the Environmental Examination Period in accordance with Section 5.5, as applicable. With respect to each potential Deferred Adjustment Claim, Buyer and Seller shall deliver to the other a written notice describing each such potential Deferred Adjustment Claim, the amount in dispute and a statement setting forth the facts and circumstances that support such party's position with respect to such Deferred Adjustment Claim. At Closing, the Purchase Price shall not be adjusted on account of, and, except as provided in Sections 9.1(f) and 9.2(f), no effect shall be given to, the Deferred Adjustment Claim. On or prior to the thirtieth (30th) consecutive calendar day following the Closing Date or, if earlier, the date which was the "Closing Date" before Closing was delayed under Section 9.4 (the "Deferred Matters Date"), the Seller and Buyer shall attempt in good faith to reach agreement on the Deferred Adjustment Claims and, ultimately, to resolve by written agreement all disputes regarding the Deferred Adjustment Claims. Any Deferred Adjustment Claims which are not so resolved on or before the Deferred Matters Date may be submitted by either party to final and binding arbitration in accordance with the Arbitration Procedures; provided, however, that the Seller may elect at any time to resolve all disputes relating to the Deferred Adjustment Claims by the payment to Buyer of the amount by which the Purchase Price would have been reduced at Closing on account of the Title Defects or Environmental Defects which constitute Deferred Adjustment Claims if same did not constitute Deferred Adjustment Claims, together with interest thereon from the Closing Date to the date of such payment at the Agreed Rate. Notwithstanding anything herein provided to the contrary, including Section 6.2(c), but without limiting Seller's rights under Sections 6.2(c)(ii) and 6.2(c)(iii), Seller shall be entitled to cure any Title Defect which constitutes a Deferred Adjustment Claim at any time prior to the point in time when a final and binding written decision of the board of arbitrators is made with respect thereto in accordance with the Arbitration Procedures. The amount of any reduction in the Purchase Price to which Buyer becomes entitled under the final and binding written decision of the board of arbitrators shall be promptly refunded by Seller to Buyer, together with interest thereon from the Closing Date to the date of payment at the Agreed Rate. Notwithstanding anything herein provided to the contrary, if Seller has disputed the existence of an Environmental Defect with respect to any Asset for which Seller has made the election set forth in Section 5.5(b)(i), to the extent that the board of arbitrators makes a final and 28 36 binding written decision that such Environmental Defect exists, Buyer shall cause the Environmental Defect Property with respect thereto to be promptly assigned by the Company to Seller or its designated transferee in accordance with Section 5.5(b) and, upon such assignment, such Environmental Defect Property shall become an Excluded Asset. Section 6.7 No Duplication. Notwithstanding anything herein provided to the contrary, if a Title Defect results from any matter which could also result in the breach of any representation or warranty of Seller set forth in Section 4.1, then Buyer shall only be entitled to assert such matter as a Title Defect pursuant to this Article VI and shall be precluded from also asserting such matter as the basis of the breach of any such representation or warranty. ARTICLE VII. TAXES AND EMPLOYEE BENEFITS Section 7.1 Tax Agreements. (a) Tax Return Filings and Tax Payments for 1997. Seller shall include the Company in its consolidated federal income Tax return, and in those state, local and foreign Tax returns that are filed on a consolidated, combined or unitary basis, for its tax period that includes the Closing Date, and Seller shall be responsible for the payment of, and shall indemnify and hold harmless the Buyer against, all Taxes required to be paid with respect to such consolidated, combined or unitary Tax Returns. Such Tax Returns shall include (a) the income and gains resulting from the purchase and sale of the Company Shares, (b) any deferred income and gain taken into income by reason of Treasury Regulation Section 1.1502-13 or any similar provision of state, local or foreign law, and (c) all other items of income, gain, loss, deduction and credit of the Company for the period up to and including the Closing Date, as determined by closing the books of the Company as of the end of the Closing Date; provided, however, such Tax Return shall not include any income, gain, loss, deduction or credit of the Company arising as a result of action of Buyer or the Company taken after the Closing. The Buyer shall cause the Company to properly file all state and local tax returns required to be filed by the Company for all taxable periods or portions thereof which include the Closing Date and which are not described in the preceding sentence, and to pay all taxes due with respect to such tax returns. (b) Tax Elections and Reporting Positions for 1996 and 1997. Without the prior written consent of Buyer, neither Seller nor the Company nor any Affiliate of Seller shall, to the extent it may affect or relate to the Company, make or change any election, change any annual tax accounting period, adopt or change any tax accounting method, file any amended return, enter into any closing agreement, settle any Tax claim or assessment, surrender any right to claim a refund of Taxes, consent to any extension or waiver of the limitation period applicable to any Tax claim or assessment, take any other action or omit to take any action, if any such election, adoption, change, amendment, agreement, settlement, surrender, consent or other action or omission would have any material adverse tax effects to the Company for any period or portion thereof beginning after the 29 37 Closing Date, or to Buyer or any Affiliate of Buyer. For purposes of the preceding sentence, the reduction of any net operating loss carryforward of the Company to a period beginning after the Closing Date resulting from any such election, adoption, change, amendment, agreement, settlement, surrender, consent or other action or omission shall not be a material adverse tax effect. Without the prior written consent of Seller, neither Buyer nor the Company nor any Affiliate of Buyer shall, to the extent it may affect or relate to the Company, make or change any election, change in the annual tax accounting period, adopt or change any tax accounting method, file any amended return, enter into any closing agreement, settle any Tax claim or assessment, surrender any right to claim a refund of taxes, consent to any extension or waiver or limitation period applicable to any Tax claim or assessment, take any other action or omit to take any action, if any such election, adoption, change, amendment, agreement, settlement, surrender, consent or other action or omission would have any material adverse tax effects to the Company with respect to any period ending on or before the Closing Date, or to the Seller, or any Affiliate of Seller. Notwithstanding the preceding sentence, however, Buyer or its Affiliates shall not be required to obtain the consent of Seller prior to entering into closing agreements or settling Tax claims or assessments of Taxes with respect to separate Tax returns filed by the Company for periods ending on or before the Closing Date, unless Seller (i) advances all Taxes and other costs incurred by Buyer or the Company in continuing to contest the Tax claims or assessments or to pursue the claims for refunds and (ii) furnishes the Buyer with an opinion of its regular outside Tax accountant or Tax counsel acceptable to Buyer that there is substantial authority for the position that is the subject of such contest of such claim or assessment.

If Buyer or its Affiliates give credit under their employee vacation plans for oil and gas industry experience, such employees shall be given credit for their years of industry experience (up to a maximum of five years) prior to the Closing Date for vacation plan purposes rather than for their years of service with the Company prior to the Closing Date.

(b) Non-Operated Properties. If the Company is not the operator of a particular portion of the Assets, the obligations of the Company in Section 8.1 above with respect to such portion of the Assets which have reference to operations or activities that pursuant to existing contracts are carried out or performed by the operator, shall be construed to require only that the Company use its reasonable best efforts (without being obligated to incur any expense or institute any cause of action) to cause the operator of such portion of the Assets to take such actions or render such performance within the constraints of the applicable operating agreements and other applicable agreements. (c) Certain Operations. (1) Should the Company not wish to pay any lease rental or other payment or participate in any reworking, deepening, drilling, completion, equipping or other operation on or with respect to any well or other Property Subdivision which may otherwise be required by Section 8.1 above, the Company shall give Buyer written notice thereof at least fifteen (15) days prior to the date such rental or other payment is due or, in the case of an operation, promptly after the Company receives notice of such proposed operation from the operator of such property (or if the Company is the operator, at the same time the Company gives or is required to give notice of such proposed operation to the non-operators of such property). The Company shall not be obligated to make any such payment or to elect to participate in any such operation which the Company does not wish to make or participate in unless the Company receives from Buyer, within a reasonable time prior to the date when such payment or election is required to be made by the Company, (a) the written election and agreement of Buyer (i) to require the Company to take such action and (ii) to pay all costs and expenses of the Company with respect to such lease rental or other payment or such operation and (b) the funds necessary for such payment or operation as contained in the applicable AFE therefor or estimated by the 36 44 Company.

(2) If a notice delivered to Buyer pursuant to Section 8.1(c)(3) sets forth a recommendation that the Company participate in an operation or capital expenditure the failure in which to participate will cause the forfeiture of all or any portion of a Subject Interest (or any interest in production attributable thereto) and the Buyer timely notifies Seller that it does not desire the Company to participate in same, then, on or before the Closing, Seller may elect to cause the Company to convey the Subject Interest (or the interest therein or interest in production therefrom) that would be so forfeited, together with a pro rata share of all Incidental Rights, oil, gas and other hydrocarbons and other assets attributable or appurtenant thereto (but only to the extent such Incidental Rights, oil, gas and other hydrocarbons and other assets are practicably severable from the Assets without adversely impacting in any material respect the value or operations of the remaining Assets; provided, however, if such Incidental Rights, oil, gas and other hydrocarbons and other assets are not so practicably severable from the Assets, upon such election by Seller, Seller shall cause the Company to execute and deliver to the transferee of said Subject Interest (or other interest) designated by Seller a perpetual use agreement on commercially reasonable terms which grants to such transferee the practical benefits such transferee would have received from such Incidental Rights, oil, gas and other hydrocarbons and other assets had they been so conveyed to such transferee) to a transferee designated by Seller and, upon such assignment, such Subject Interest or portion thereof so transferred shall become an Excluded Asset.

In each case to which such exception applies, the releasing party will use its reasonable best efforts to provide a copy of such release or statement to the other party prior to releasing or making the same. Section 8.4 Actions by Parties. Each of the parties agrees to use its reasonable best efforts to satisfy the conditions to Closing set forth in Article IX and to refrain from taking any action within its control which would cause a breach by such party of a representation or warranty set forth herein; provided, however, that neither Seller nor any Affiliate of Seller (other than the Company) shall be required to expend any funds or incur any costs to prevent or cure a breach of the representations and warranties set forth in Section 4.1 with respect to the Company. Section 8.5 Amendment of Schedules.

Section 13.2 Indemnification By Seller. Subject to the provisions of Section 13.4, from and after the Closing Date, Seller shall indemnify and hold harmless the Buyer, Buyer's Affiliates, the Company, each of their respective present and future directors, officers, employees, consultants and agents, and each of the directors, officers, heirs, executors, successors and assigns of any of the foregoing (collectively, the "Buyer Indemnified Parties") from and against any and all (i) Seller Environmental Obligations and Excluded Liabilities incurred by or asserted against any of the Buyer Indemnified Parties, INCLUDING, WITHOUT LIMITATION, ANY EXCLUDED LIABILITY BASED ON NEGLIGENCE, GROSS NEGLIGENCE OR STRICT LIABILITY OF THE BUYER INDEMNIFIED PARTY OR ANY OTHER THEORY OF LIABILITY, WHETHER IN LAW (WHETHER COMMON OR STATUTORY) OR EQUITY and (ii) subject to the limitations of Section 11.1 and Article XII, any Covered Liability resulting from, arising out of or on account of any breach, failure or nonfulfillment of any representation, warranty, covenant or agreement on the part of Seller which is expressly set forth in this Agreement.

If a claim by a third party is made against a Seller Indemnified Party or a Buyer Indemnified Party (an "Indemnified Party"), and if such party intends to seek indemnity with respect thereto under Section 5.1, 5.4, 6.6, 8.8, 13.1 or 13.2, such Indemnified Party shall promptly furnish written notice to Buyer or Seller, as the case may be (the "Indemnitor"), of such claims. The Indemnitor shall have thirty (30) days after receipt of such notice to undertake, conduct and control, through counsel of its own choosing and at its own expense, the settlement or defense thereof, and the Indemnified Party shall cooperate with it in connection therewith; provided that the Indemnitor shall permit the Indemnified Party to participate in such settlement or defense through counsel chosen by such Indemnified Party, however, the fees and expenses of such counsel shall be borne by such Indemnified Party. So long as the Indemnitor, at Indemnitor's cost and expense, (1) has undertaken the defense of, and assumed full responsibility for all indemnified liabilities with respect to, such claim, (2) is reasonably contesting such claim in good faith, by appropriate proceedings, and (3) has taken such action (including the posting of a bond, deposit or other security) as may be necessary to prevent any action to foreclose a lien against or attachment of the property of the Indemnified Party for payment of such claim, the Indemnified Party shall not pay or settle any such claim. Notwithstanding compliance by the Indemnitor with the preceding sentence, the Indemnified Party shall have the right to pay or settle any such claim, provided that in such event it shall waive any right to indemnity therefor by the Indemnitor for such claim. If, within thirty (30) days after the receipt of the Indemnified Party's notice of a claim of indemnity hereunder, the Indemnitor does not notify the Indemnified Party that it elects, at Indemnitor's cost and expense, to undertake the defense thereof and assume full responsibility for all indemnified liabilities with respect thereto, or gives such notice and thereafter fails to contest such claim in good faith or to prevent action to foreclose a lien against or attachment of the Indemnified Party's property as contemplated above, the Indemnified Party shall have the right to contest, settle and/or compromise the claim and, to the extent the actions, if any, taken by the Indemnified Party in settling or compromising such claim are reasonable and in good faith, the Indemnified Party shall not thereby waive any right to indemnity therefor pursuant to this Agreement. Section 13.4 Seller's General Liability Limitation. (a) Notwithstanding anything herein provided to the contrary, (1) Seller shall have no liability to Buyer or any of the other Buyer Indemnified Parties pursuant to Section 13.2 to the extent that the aggregate of all (a) Seller Environmental Obligations described in clause (i) of Section 13.2 and (b) Covered Liabilities described in clause (ii) of Section 13.2 exceed an amount equal to the sum of the amount of the Deposit plus the Adjusted Purchase Price (as same may be further adjusted downward after the Closing pursuant to Section 6.6) and (2) without in any way limiting the generality of clause (1) above or any obligation of Seller for Excluded Liabilities, Deferred Adjustment Claims or pursuant to the election by Seller of the option set forth in Section 5.5(b)(ii), Seller Environmental Obligations are the only obligations of Seller with respect to Environmental Matters after Closing. 49 57 (b) Notwithstanding anything herein provided to the contrary but without in any way affecting the obligations of a Buyer Indemnified Party to notify the Seller of a third party claim pursuant to Section 13.3, Seller shall not have any liability to a Buyer Indemnified Party pursuant to Section 13.2 unless and until the Company enforces any and all of the rights and remedies that the Company may have against any Person pursuant to agreements for insurance, indemnification, guarantee or similar assurances; provided that, if any such third party indemnitor or guarantor refuses to accept and perform its obligations to the Company after the Company has used its reasonable best efforts (other than instituting an Action) for a period not to exceed 30 days to obtain such acceptance and performance from such third party indemnitor or guarantor, then the Company may notify the Seller of such refusal and the Seller shall perform its indemnity obligations under Section 13.2 without first requiring the Company to bring an Action against such third party indemnitor or guarantor. In the event of such refusal by a third party indemnitor or guarantor to accept and perform its obligations to the Company, then the Company, at the request, control, direction and expense of the Seller, will institute and pursue an Action and otherwise enforce its rights and remedies under such third party indemnity or guarantee for the benefit of Seller. ARTICLE XIV. TERMINATION; REMEDIES; LIMITATIONS Section 14.1 Termination. (a) Termination of Agreement. This Agreement and the transactions contemplated hereby may be terminated at any time prior to the Closing: (1) By the mutual consent of Seller and Buyer; or (2) If the Closing has not occurred by the close of business on the Closing Date, then (i) by Seller if any condition specified in Section 9.1 has not been satisfied on or before such close of business, and shall not theretofore have been waived by Seller, or (ii) by Buyer if any condition specified in Section 9.2 has not been satisfied on or before such close of business, and shall not theretofore have been waived by Buyer; provided, in each case, that the failure to consummate the transactions contemplated hereby on or before such date did not result from the failure by the party or parties seeking termination of this Agreement to fulfill any undertaking or commitment provided for herein on the part of such party or parties that is required to be fulfilled on or prior to Closing. (b) Effect of Termination. Without limiting Seller's and Buyer's respective remedies and rights in regard to the Deposit under Section 14.2, in the event of termination of this Agreement by Seller, on the one hand, or Buyer, on the other hand, pursuant to Section 14.1(a), written notice thereof shall forthwith be given by the terminating party or parties to the other party or parties hereto, and this Agreement shall thereupon terminate; provided, however, that following 50 58 such termination Buyer will continue to be bound by its obligations set forth in Sections 5.1, 5.2 and 5.4.

Seller and Buyer agree upon the Deposit amount together with all interest and other amounts earned thereon, as liquidated damages due to the difficulty and inconvenience of measuring actual damages and the uncertainty thereof, and Seller and Buyer agree that such amount is a reasonable estimate of Seller's loss in the event of any such failure by Buyer. (b) Buyer's Remedies. Notwithstanding anything herein provided to the contrary, upon failure of the Seller to satisfy the conditions to Closing or the Closing obligations, as the case may be, set forth in (i) item (1) of clause (a) of Section 9.2 on account of breaches of the representations and warranties made by Seller on and as of the date of this Agreement, (ii) item (2) of clause (a) of Section 9.2, (iii) clause (b) of Section 9.2 on account of breaches of the representations and warranties made by Seller on and as of the date of this Agreement or the failure by Seller to satisfy the condition set forth in item (2) of clause (a) of Section 9.2, (iv) clause (e) of Section 9.2, or (v) clauses (a), (d) or (e) of Section 10.2 on or prior to the Closing Date, Buyer, at its sole option, may (i) enforce specific performance of this Agreement or (ii) terminate this Agreement and receive back the Deposit, together with all interest and other amounts earned thereon, as Buyer's sole and exclusive remedies for such failure, all other remedies being expressly waived by Buyer; provided, however, if Seller fails to satisfy the conditions to Closing set forth in item (2) of clause (a) of Section 9.2, such failure results from Seller's breach of its agreement set forth in Section 8.11, and Buyer elects pursuant to this Section 14.2(b) to terminate this Agreement and receive back the Deposit, together with all interest and other amounts earned thereon, then, in addition to receiving back the Deposit and such interest and other amounts Buyer shall be entitled to be paid $15,000,000 by Seller as liquidated damages within 5 business days of such termination. Seller and Buyer agree upon such amount as liquidated damages due to the difficulty and inconvenience of measuring actual damages and the uncertainty thereof, and Seller and Buyer agree 51 59 that such amount is a reasonable estimate of Buyer's loss in the event of the occurrence described in the proviso of the immediately preceding sentence.

Appendix A, Page 15 80 APPENDIX B TO STOCK PURCHASE AGREEMENT CORRECTIVE ACTION PROJECTS 1. Implementation Of Corrective Action Projects. If as a result of any Environmental Liabilities, any Buyer Indemnified Party is required to implement any Corrective Action projects which will cause any Buyer Indemnified Party to incur costs qualifying as Seller Environmental Obligations and for which a Buyer Indemnified Party will seek reimbursement in whole or in part from Seller, the Buyer Indemnified Party shall propose to Seller a plan (the "Plan") for such work. Prior to the implementation of any Plan or Plans, the Buyer Indemnified Party shall provide Seller with a comprehensive schedule showing in reasonable detail the Corrective Actions to be taken by the Buyer Indemnified Party to comply with such Plans and a budget showing the estimated timing and estimated amount of expenditures required to implement the Plans. Seller and the Buyer Indemnified Party from time to time shall meet and consult with one another fully with respect to each such Plan, schedule and budget and, not less than once each calendar quarter (commencing with the first full calendar quarter after Closing), the Buyer Indemnified Party shall provide Seller with an updated comprehensive schedule showing in reasonable detail the current status of all Corrective Actions undertaken by the Buyer Indemnified Party since the Closing Date (including expenditures to date) and an updated version of said budget. The Buyer Indemnified Party shall be required to obtain Seller's prior approval (which shall not be unreasonably withheld or delayed) for each Plan and the budget and schedule therefor prior to proceeding with any Plan or any individual project therein. Seller shall be deemed to have approved such Plan, budget and schedule unless Seller shall have objected thereto by notice to the Buyer Indemnified Party within twenty (20) days following Seller's receipt thereof setting forth in reasonable detail the basis for Seller's objections. If Seller objects to such proposed Plan and the Buyer Indemnified Party and Seller do not reach agreement on such objections, then Seller shall provide the Buyer Indemnified Party with an alternative Plan as soon as reasonably practicable in light of the circumstances following Seller's receipt of a request therefor from the Buyer Indemnified Party. 2. Payment Procedures. On or before the 15th day of each month, the Buyer Indemnified Party shall provide Seller with a schedule setting forth amounts paid during the preceding month for goods or services actually provided or performed, or damages or expenses paid, any portion of which constitutes Seller Environmental Obligations, including the portion thereof which the Buyer Indemnified Party is obligated to bear. The Buyer Indemnified Party shall also provide Seller with copies of invoices and such other supporting data as Seller may reasonably request regarding the amounts set forth in such schedule. Subject to paragraph 3, payment for such amounts shall be due from Seller on or before the last day of the month immediately following the month during which the schedule is received by Seller. 3. Arbitration. If a dispute shall arise between the parties concerning any Seller Environment Obligation or any Corrective Action, including (a) whether Seller's approval of a Plan, Appendix B, Page 1 81 budget and schedule or any portion thereof has reasonably been withheld or (b) whether an amount submitted to Seller for payment pursuant to paragraph 2 is a Seller Environmental Obligation and a reasonable and necessary cost for curing or remediating the Environmental Liability giving rise to such Seller Environmental Obligation, then either Seller or the Buyer Indemnified Party shall have the right to notify the other that the notifying party is electing to submit the dispute to arbitration. Arbitration will be conducted in accordance with Section 15.10 of the Agreement. Appendix B, Page 2
