(a) With respect to each Tax Return covering a taxable period ending on or before the Closing Date that is required to be filed after the Closing Date for, by or with respect to the Company or any subsidiary of the Company (other than the Tax Returns described in subsection (c) of this Section), the Seller shall cause such Tax Return to be prepared, shall cause to be included in such Tax Return all items of income, gain, loss, deduction and credit or other items (collectively "Tax Items") required to be included therein, and shall deliver the original of such Tax Return to the Purchaser at least thirty (30) days prior to the due date (including extensions) of such Tax Return. If the amount of the Tax shown to be due on such Tax Return exceeds the amount of the Closing Date Tax Accrual for such Tax, the Seller shall pay to the Purchaser the amount of such excess 23 not less than five (5) days prior to the due date of such Tax Return. If the amount of the Tax shown to be due on such Tax Return is less than the amount of the Closing Date Tax Accrual for such Tax, the Purchaser shall pay to the Seller the amount of such difference not less than five (5) days prior to the due date of such Tax Return. The Purchaser shall cause the Company or the respective subsidiary to file timely such Tax Return with the appropriate taxing authority and to pay the amount of Taxes shown to be due on such Tax Return. (b) With respect to each Tax Return covering a taxable period beginning on or before the Closing Date and ending after the Closing Date that is required to be filed after the Closing Date for, by or with respect to the Company or any subsidiary of the Company (other than the Tax Returns described in subsection (c) of this Section), the Purchaser shall cause such Tax Return to be prepared and shall cause to be included in such Tax Return all Tax Items required to be included therein. The Purchaser shall determine, subject to verification by the Seller, the portion, if any, of the Tax due with respect to the period covered by such Tax Return which is attributable to the Company or the respective subsidiary for a Pre-Closing Taxable Period. The determination of the portion of such Tax that is attributable to the Pre-Closing Period shall be based, in the case of real and personal property Taxes, on a per diem basis and, in the case of other Taxes, on the actual activities, taxable income or taxable loss of the Company and its subsidiaries during the Pre-Closing Period and Post-Closing Period. At least thirty (30) days prior to the due date (including extensions) of such Tax Return, the Purchaser shall deliver to the Seller a copy of such Tax Return. If the amount of Tax attributable to the Pre-Closing Taxable Period exceeds the amount of the Closing Date Tax Accrual for such Tax, the Seller shall pay to the Purchaser the amount of such excess Tax not less than five (5) days prior to the due date of such Tax Return. If the amount of Tax attributable to the Pre- Closing Taxable Period is less than the amount of the Closing Date Tax Accrual for such Tax, the Purchaser shall pay to the Seller the amount of such difference not less than five (5) days prior to the due date of such Tax Return. The Purchaser shall cause the Company or the respective subsidiary to file timely such Tax Return with the appropriate taxing authority and to pay timely the amount of Taxes shown to be due on such Tax Return. For purposes of this subsection, (i) any Texas franchise Tax imposed on the Taxable Earned Surplus of the Company or any of its subsidiaries which is determined with reference to the federal taxable income of the Company or any of its subsidiaries for the period up to and including the Closing Date shall be treated as attributable to a Pre-Closing Taxable Period, and (ii) any state income or franchise Tax (other than Texas franchise Tax) which is imposed on the Company or any of its subsidiaries in a Post-Closing Taxable Period and is determined by reference to federal taxable income of a Pre-Closing Taxable Period of the Company or any of its subsidiaries shall be treated as attributable to a Pre-Closing Taxable Period. (c) The Seller shall cause to be included in the consolidated federal income Tax Returns (and the state income Tax Returns of any state in which the Seller files consolidated, combined or unitary income Tax Returns) of the Seller's Group for all periods ending on or before or which include the Closing Date, all Tax Items of the Company and its subsidiaries which are required to be included therein, shall file timely all such Tax Returns with the appropriate taxing authorities and shall pay timely all Taxes due with respect to the periods covered by such Tax Returns. 24 (d) The Seller shall be responsible for the payment of all state and local transfer, sales, use or other similar taxes resulting from the transactions contemplated by this Agreement. (e) From time to time prior to the Closing Date, the Seller shall have the right to cause the Company or any of its subsidiaries to pay to the IRS or the applicable state taxing authority (or to the Seller or another member of the Seller's Group as agent for the payment of such Tax) such amounts on account of the Company's and the subsidiaries' shares of consolidated federal income Tax liability and any consolidated, combined or unitary state income Tax liability of the Seller's Group for the 1996 taxable year as are consistent with any tax sharing agreements, arrangements, policies or guidelines ("Tax Sharing Agreements") that may exist between the Company or any subsidiary of the Company, on the one hand, and the Seller or any other Affiliate of the Seller, on the other. All such Tax Sharing Agreements will be terminated and any obligations to make payments under them shall be canceled as of the Closing Date. Any and all payments then remaining due under those Tax Sharing Agreements shall be made prior to their termination. Section 6.07. Access to Information. From and after the Closing: (a) The Seller and each member of the Seller's Group shall grant to the Purchaser (or its designees) access at all reasonable times to all of the information, books and records relating to the Company and its subsidiaries within the possession of the Seller or any member of the Seller's Group (including work papers and correspondence with taxing authorities), and shall afford to the Purchaser (or its designees) the right (at the Purchaser's expense) to take extracts therefrom and to make copies thereof, to the extent reasonably necessary to permit the Purchaser or any of its Affiliates (or its designees) to prepare Tax Returns, to conduct negotiations with Tax authorities, to fulfill an obligation to any Governmental Authority imposed by Law, Regulation or Order and to implement the provisions of, or to investigate or defend any claims between the parties arising under, this Agreement. (b) The Purchaser shall grant or cause the Company and its subsidiaries to grant to the Seller or any of its Affiliates (or its designees) access at all reasonable times to all of the information, books and records relating to the Company and its subsidiaries within the possession of the Purchaser, the Company or its subsidiaries (including work papers and correspondence with taxing authorities), and shall afford to the Seller (or its designees) the right (at the Seller's expense) to take extracts therefrom and to make copies thereof, to the extent reasonably necessary to permit the Seller (or its designees) to prepare Tax Returns, to conduct negotiations with Tax authorities, to fulfill an obligation to any Governmental Authority imposed by Law, Regulation or Order and to implement the provisions of, or to investigate or defend any claims between the parties arising under, this Agreement or otherwise. (c) Each of the parties hereto will preserve and retain all schedules, work papers and other documents relating to any Tax Returns of or with respect to the Company or any of its subsidiaries or to any claims, audits or other proceedings affecting the Company or any of its subsidiaries until the expiration of the statute of limitations (including extensions) 25 applicable to the taxable period to which such documents relate or until the final determination of any controversy with respect to such taxable period, and until the final determination of any payments that may be required with respect to such taxable period under this Agreement. (d) Notwithstanding the foregoing provisions of this Section, neither party hereto shall be required to grant or cause to be granted to the other access to information, books and records or to furnish extracts or copies thereof if such information, books and records also include information regarding such party or any of its Affiliates. In such circumstances, such party shall either provide appropriately detailed summaries of the information contained therein or , in providing extracts or copies thereof, redact the information relating to such party or its Affiliates. Section 6.08. Employees and Employee Benefit Plans. (a) Effective as of the Closing, the Seller shall cause the Company to withdraw as a participating employer from all Benefit Plans other than any Benefit Plans as to which the Company is the sole sponsoring entity. (b) Effective as of the Closing, the Seller shall cause each employee of the Company on the Closing Date (the "Continuing Employees") who is a participant in the Central and South West System Pension Plan (the "CSW Pension Plan") on the Closing Date to become 100% vested in his accrued benefit under the CSW Pension Plan as of the Closing and shall cause the accrued benefits of the Continuing Employees under the CSW Pension Plan to be distributed to such Continuing Employees pursuant to the terms and provisions of the CSW Pension Plan as if the Continuing Employees had terminated employment for purposes of the CSW Pension Plan as of the Closing. Effective as of the Closing, the Purchaser shall take all action necessary and appropriate to extend coverage under a new or existing defined benefit pension plan (the "Purchaser's Pension Plan") qualified under section 401(a) of the Code to the Continuing Employees who were participants in the CSW Pension Plan at the Closing. The Continuing Employees shall be credited with service under the Purchaser's Pension Plan, for eligibility, vesting, and accrual of benefit purposes, with the service credited to them for such purposes under the CSW Pension Plan as of the Closing. The Continuing Employees' benefits under the Purchaser's Pension Plan shall be reduced by the actuarial equivalent of the pension benefit paid or payable to such Continuing Employees from the CSW Pension Plan. In making such reduction, the pension paid or payable under each plan shall be determined under the provisions of each plan as if payable at normal retirement date in the normal form; provided, however, that the pension benefit paid or payable under the CSW Pension Plan in the normal form at the normal retirement date shall be converted to the normal form under the Purchaser's Pension Plan using the actuarial assumptions under the Purchaser's Pension Plan. The net pension payable under the Purchaser's Pension Plan shall then be actuarially adjusted in accordance with the provisions of the Purchaser's Pension Plan for the actual time and form of payment. (c) Effective as of the Closing, the Purchaser shall take all action necessary and appropriate to extend coverage under a new or existing defined contribution plan (the "Purchaser's Savings Plan") qualified under section 401(a) of the Code to the 26 Continuing Employees who have account balances under the Central and South West System Thrift Plus Plan (the "CSW Thrift Plan") at the Closing. The Continuing Employees shall be credited with service under the Purchaser's Savings Plan, for eligibility and vesting purposes, with the service credited to them under the terms of the CSW Thrift Plan as of the Closing. As soon as practicable following the Closing, the Seller shall cause to be transferred from the trustee of the CSW Thrift Plan to the trustee of the Purchaser's Savings Plan an amount in cash or in kind (with any in kind transfers to be agreed upon by the Seller and the Purchaser, except that it is hereby agreed that participant loans shall be transferred in kind; provided, however, that any loan repayments shall be applied to investments available under the Purchaser's Savings Plan) equal to the aggregate account balances (both vested and unvested) of the Continuing Employees under the CSW Thrift Plan determined as of the transfer date (which shall be a valuation date) in accordance with the methods of valuation set forth in the CSW Thrift Plan. From and after the date of such transfer, the Purchaser shall cause the Purchaser's Savings Plan to assume the obligations of the CSW Thrift Plan with respect to the benefits accrued by the Continuing Employees under the CSW Thrift Plan, and the CSW Thrift Plan shall cease to be responsible therefor. (d) Except as provided in subsections (e), (f), and (j) of this Section, claims for benefits under welfare plans, as such term is defined in Section 3(1) of ERISA, in which Continuing Employees participate arising out of occurrences prior to the Closing shall be covered by the applicable welfare plan of the Seller in accordance with the terms of such plan. All such claims for benefits by Continuing Employees arising out of occurrences subsequent to the Closing shall be covered by the applicable welfare plan of the Purchaser in accordance with the terms of such plan. Neither the Purchaser nor any of its subsidiaries shall be liable for payment of any disability benefit due to disabled employees of the Company or its subsidiaries or Continuing Employees who, prior to the Closing, are in the waiting or qualifying period for disability benefits. After the Closing, the Seller shall be responsible for disability benefits payable to such persons under the Seller's disability plan. (e) Claims for medical, dental, prescription drug, vision, and employee assistance plan benefits by Continuing Employees with respect to purchases or services or treatment rendered prior to the Closing shall be covered by the applicable welfare plan of the Seller in accordance with the terms of such plan. Claims for such benefits by Continuing Employees with respect to purchases or services or treatment rendered on or subsequent to the Closing shall be covered by the applicable welfare plan of the Purchaser in accordance with the terms of such plan. The Purchaser shall cause the Continuing Employees to be granted credit under the welfare plan of the Purchaser providing medical, dental, prescription drug, vision, and employee assistance plan coverage, for the year during which the Closing occurs, for any deductibles already incurred by such Continuing Employees for such year under the welfare plan of the Seller providing such coverage, and the Purchaser shall cause to be waived any eligibility waiting periods and pre-existing condition restrictions under the welfare plans of the Purchaser to the extent necessary to provide immediate coverage under such welfare plans as of the Closing (but only to the extent that coverage was provided under the applicable welfare plan of the Seller). The Purchaser shall provide the Continuing Employees (and their respective beneficiaries) with medical benefits sufficient to satisfy the obligations of the Seller under Section 4980B(f) of the Code with respect to such Continuing Employees so that the Seller will not incur any tax under Section 4980B of the Code. 27 (f) Effective as of the Closing, the Purchaser shall, or shall cause the Company to, take all action necessary and appropriate to extend coverage under a new or existing health care spending account plan (the "Purchaser's Health Care Plan") to the Continuing Employees. A Continuing Employee shall be considered to have an account balance under the Purchaser's Health Care Plan following the Closing that is the same as such Continuing Employee's account balance under the Central and South West System Health Care Reimbursement Plan (the "CSW Health Care Plan") immediately prior to the Closing, and the elections in effect for the year in which the Closing Date occurs under the CSW Health Care Plan shall remain in effect under the Purchaser's Health Care Plan for the remainder of such year unless changed as a result of a change in family status. As of the Closing, the positive and negative balances of the Continuing Employees under the CSW Health Care Plan shall be netted. To the extent that there is a net positive balance, claims under the Purchaser's Health Care Plan following the Closing shall be paid from the Central and Southwest System Voluntary Employees' Beneficiary Association (the "CSW VEBA") until such balance is eliminated. Thereafter, all such claims shall be paid by the Company. To the extent that there is a net negative balance as of the Closing, the Company shall make a contribution to the CSW VEBA as of or before the Closing equal to the net negative balance. For purposes of this paragraph, a Continuing Employee shall be considered to have a positive balance in such employee's account as of the Closing if the amounts that have been withheld from such Continuing Employee's compensation during the year in which the Closing occurs, pursuant to the CSW Health Care Plan, prior to the Closing, exceeded disbursements on such Continuing Employee's behalf from the CSW Health Care Plan prior to the Closing for such year's claims. A Continuing Employee shall be considered to have a negative balance in such Continuing Employee's account as of the Closing if the disbursements on such Continuing Employee's behalf from the CSW Health Care Plan prior to the Closing for the year in which the Closing occurs exceeds the amounts that have been withheld from such Continuing Employee's compensation during such year, pursuant to the CSW Health Care Plan, prior to the Closing. (g) Effective as of the Closing, the Purchaser shall, or shall cause the Company to, take all action necessary and appropriate to extend coverage under a new or existing dependent care spending account plan (the "Purchaser's Dependent Care Plan") to the Continuing Employees. A Continuing Employee shall be considered to have an account balance under the Purchaser's Dependent Care Plan following the Closing that is the same as such Continuing Employee's account balance under the Central and South West System Dependent Care Assistance Plan (the "CSW Dependent Care Plan") immediately prior to the Closing, and the elections in effect for the year in which the Closing Date occurs under the CSW Dependent Care Plan shall remain in effect under the Purchaser's Dependent Care Plan for the remainder of such year unless changed as a result of a change in family status. To the extent that there are amounts held in the CSW VEBA as of the Closing attributable to a Continuing Employee's participation in the CSW Dependent Care Plan, claims under the Purchaser's Dependent Care Plan following the Closing shall be paid from the CSW VEBA until such amounts are depleted. Thereafter, all such claims shall be paid by the Company. (h) For a period of one year following the Closing Date, the Purchaser shall, or shall cause the Company to, establish and manage a severance benefit plan to cover the Continuing Employees with such severance benefit being a severance benefit plan 28 substantially similar to the Central and South West System Severance Benefit Plan, effective July 1, 1995 (the "CSW Severance Benefit Plan"). For purposes of such plan, any restructuring, reorganization, or other position elimination involving a Continuing Employee shall be considered approved within the meaning of Section 2.1 of the CSW Severance Benefit Plan and service with the Seller or any of its subsidiaries, including the Company, shall be taken into account. (i) Vacation entitlement accrued by Continuing Employees for the year in which the Closing Date occurs under the Company's vacation policy as in effect as of the Closing shall be recognized by the Purchaser and the Company following the Closing. Service with the Seller or any of its subsidiaries, including the Company, shall be taken into account for purposes of the Purchaser's vacation policy following the Closing. (j) With respect to all employees who retired from employment with the Company prior to the Closing and who have been, or are eligible to be, provided with post-retirement medical, dental, or life insurance coverage as of the Closing under plans sponsored by the Seller or the Company, the Seller shall assume or retain any and all liability with respect to the provision of such coverages to such retired employees and their eligible dependents on and after the Closing. With respect to all Continuing Employees who retire from employment with the Company after the Closing and who have been, or are eligible to be, provided with post-retirement medical, dental or life insurance as of the Closing under plans sponsored by the Company or the Seller, the Purchaser shall assume any and all liability with respect to the provision of such coverages to such retired Continuing Employees and their eligible dependents on and after the Closing (up to a present benefit obligation of $3.2 million, computed using the actuarial assumptions of the CSW Pension Plan). (k) Claims for workers compensation benefits for Continuing Employees arising out of occurrences prior to the Closing shall be the responsibility of the Seller. Claims for workers compensation benefits for Continuing Employees arising out of occurrences subsequent to the Closing shall be the responsibility of the Purchaser. (l) Nothing herein shall be deemed or construed to give rise to any rights, claims, benefits, or causes of action to any Continuing Employee or any other Person, except the Seller or to prevent, restrict, or limit the Purchaser or the Company and its subsidiaries following the Closing from modifying or terminating its pension or other benefit plans, programs, or policies from time to time as it may deem appropriate, subject only to compliance with the express provisions of subsections (a) through (k) of this Section for the benefit of the Seller. Section 6.09. Working Capital Contribution. Effective as of the Closing, the Seller shall cause the purchase agreement dated January 2, 1991, between the Company and CSW Credit, Inc. pursuant to which the Company factors its trade accounts receivable to CSW Credit, Inc. to be amended to terminate the factoring of accounts receivable of the Company arising after the Closing, the Company's intercompany payable or receivable balance, as the case may be, in the CSW Money Pool to be forgiven in full resulting in a capital contribution (or resulting in a distribution), and (c) to be assigned (without recourse) to the 29 Company, as a capital contribution, the right, title and interest in and to the amount of current accounts receivable balances existing as of the Closing that are required to bring the Working Capital of the Company as of the Closing to zero (after giving effect to clause (b) of this Section and Section 6.10(a)) and that have been factored by the Company to CSW Credit, Inc. pursuant to such purchase agreement. Section 6.10. Intercompany Accounts; Post-Closing Relationships; Closing Covenants. (a) Except for the Company's intercompany payable or receivable balance, as the case may be, in the CSW Money Pool (which is specifically addressed in Section 6.09), and except for those accounts set forth in Section 6.10(a) of the Seller's Disclosure Letter, the Seller, effective as of the Closing, will cause all intercompany accounts (including those pertaining to all income taxes) between the Company and its subsidiaries, on the one hand, and the Seller and its Affiliates (other than the Company and its subsidiaries), on the other, to be paid or otherwise satisfied. (b) Effective as of the Closing, the only obligations of the Company and its subsidiaries to the Seller and its Affiliates (other than the Company and its subsidiaries) and of the Seller and its Affiliates (other than the Company and its subsidiaries) to the Company and its subsidiaries shall be those obligations expressly set forth in the contracts listed in Section 6.10(b) of the Seller's Disclosure Letter, irrespective of any prior relationships, arrangements, business practices or courses of dealing and any forecasts, estimates or projections related to the subject matter of such contracts. (c) The Seller agrees to assign to the Company, at or prior to the Closing, the confidentiality agreements with all other prospective purchasers of the Company. (d) At the Purchaser's request, the Seller agrees to provide the transition services described in Annex B to this Agreement to the Company until April 15, 1997 at a level sufficient to effect a smooth transfer of the ownership and operation of the Company by the Seller to the Purchaser, and the Purchaser agrees to pay the Seller the cost of such services (consistent with the payment for similar services made in the past under that certain agreement among Central and South West Services, Inc., the Company and certain Affiliates of the Company dated August 18, 1988). (e) As of the Closing, the Seller shall cause the Company and its subsidiaries to have no outstanding long term indebtedness for borrowed money which would be required to be reflected under GAAP in the consolidated financial statements of the Company as of the Closing, other than any such indebtedness reflected in the Consolidated Financial Statements and the debt secured by the real estate mortgages disclosed in Section 4.07(a) of the Seller's Disclosure Letter. (f) The Seller agrees to use commercially reasonable efforts to cooperate with the Company and its subsidiaries after the Closing in making and prosecuting claims under insurance policies and programs of the Seller and its Affiliates that cover the Company and its subsidiaries. The insurance trust of which the Seller is a member under the Trust Agreement dated November 1, 1990 (the "Trust"), will continue to process, respond to, defend, and pay claims received prior to the Closing. The 30 Company and its subsidiaries will process, respond to, defend, and pay claims made after the Closing; provided, however, that the Company and its subsidiaries after the Closing will continue to be entitled to make claims against insurance policies purchased by the Trust prior to the Closing in which the Company and its subsidiaries are named as insureds in accordance with the terms of such policies so long as such insurance policies remain in effect, but the Company and its subsidiaries will not make claims against the Trust or Trust assets for claims made after the Closing. The Seller shall cause no premiums or assessments to be due and payable from the Company and its subsidiaries to the Trust (and no distributions or refunds to be due and payable from the Trust to the Company and its subsidiaries) after the Closing. (g) Prior to or at the Closing the Seller shall enter into, or cause Public Service Company of Oklahoma to enter into, an agreement providing for the indemnity to the Company and its subsidiaries described in the seventh paragraph of Note 10 to the Consolidated Financial Statements as such indemnity relates to the claims against the Company or such subsidiaries described in such paragraph or similar claims against the Company or such subsidiaries made subsequent to December 31, 1995 that relate to events occurring or circumstances existing prior to the Closing. Such agreement shall contain terms similar to those set forth in Sections 8.02(e) and (f) regarding the defense and settlement of claims, but in any event shall be in form and substance reasonably acceptable to the Purchaser. Section 6.11. Estimated Purchase Price. At least three (3) days prior to the Closing, the Seller in good faith shall prepare in reasonable detail and deliver to the Purchaser a statement setting forth the Seller's calculations with respect to its best estimation of the Purchase Price, including its best estimation of the amount of Working Capital of the Company as of the Closing (the "Estimated Purchase Price"). Section 6.12. Determination of Final Purchase Price. As soon as reasonably practicable and in any event within sixty (60) days following the Closing Date, the Purchaser shall cause the Company to prepare and deliver to the Seller a statement setting forth the Purchaser's calculation (the "Final Purchase Price Calculation") of the final purchase price (the "Final Purchase Price"), including the actual amount of Working Capital of the Company as of the Closing and, if the Final Purchase Price differs from the Estimated Purchase Price, the reasons therefor in reasonable detail. The Final Purchase Price Calculation shall contain sufficient detail to enable the Seller to relate the calculations contained therein to the books and records of the Company and its subsidiaries. The Purchaser shall cause the Company to make available to the Seller all information in the possession of the Company and its subsidiaries reasonably required for the Seller to verify whether the Final Purchase Price Calculation is correct. Within forty-five (45) days following the delivery of the Final Purchase Price Calculation, the Seller shall notify the Purchaser whether it agrees with the Final Purchase Price Calculation; provided, however, that, if the Seller shall fail so to notify the Purchaser within such forty- five (45) day period, it shall be deemed to have agreed with the Final Purchase Price Calculation. If the Seller shall disagree with the Final Purchase Price Calculation, the Seller and the Purchaser shall endeavor in good faith to agree on the Final Purchase Price but, if they shall not agree within thirty (30) days following the Seller's notice to the Purchaser, either the Purchaser or the Seller may cause the issues in dispute to be referred for resolution to Price Waterhouse L.L.P. (or such other firm of independent public accountants as the Purchaser and the Seller may mutually designate), and the Seller and the Purchaser 30 shall cooperate, and the Purchaser shall cause the Company and its subsidiaries to cooperate, with such firm of independent public accountants by making available to that firm such information, books and records and such personnel as such firm may reasonably request. The costs of such firm of independent public accountants shall be borne equally by the Purchaser and the Seller. The Purchaser and the Seller shall use all commercially reasonable efforts to cause such firm of independent public accountants to examine the books and records of the Company and its subsidiaries, as well as any other information that such firm may reasonably conclude is necessary to make such determination, and to make a determination with respect to such issues within sixty (60) days following the date such issues are referred to them. Any such determination shall be final and binding on the Purchaser and the Seller and may be enforced by appropriate judicial or other proceedings. The Final Purchase Price shall then be calculated by the Seller and the Purchaser based on those matters as to which they are in agreement and the determination by the independent public accountants as to those matters, if any, as to which they did not agree. If the Final Purchase Price as so determined (whether by agreement of the parties or determination by accountants) shall exceed the Estimated Purchase Price, the Purchaser shall pay the Seller the amount of such excess plus interest thereon from the Closing Date until paid at a rate equal to the base or reference rate quoted from time to time by the Bank, but, if the Final Purchase Price as so determined shall be less than the Estimated Purchase Price, the Seller shall pay the Purchaser the amount of such shortfall plus interest thereon from the Closing Date until paid at a rate equal to the base or reference rate quoted from time to time by the Bank, such payment in either case to be made within five (5) days following the final determination of the Final Purchase Price. Section 6.13. Public Announcements. Except as otherwise required by Law or the New York Stock Exchange, the Seller and the Purchaser shall consult with each other before issuing any press release or otherwise making any public statements with respect to this Agreement and the transactions contemplated hereby and shall not issue any such press release or make any such public statement prior to such consultation. The press release announcing the execution and delivery of this Agreement shall be a joint press release of the Seller and the Purchaser. Section 6.14. Confidentiality. After the Closing, the Seller will not, and will not permit its Affiliates which it controls (excluding the Company and its subsidiaries) to, disclose or provide to any other Person any material non-public information of a confidential nature concerning the business or operations of the Company or its subsidiaries, except as required by Law, Regulation or Order. Section 6.15. Acquisition Proposals. From the execution of this Agreement by the Seller until the Closing or the termination of this Agreement in accordance with its terms, the Seller will not, and will cause its officers, directors, employees or agents not to, directly or indirectly, take any action to solicit, initiate or encourage any proposal regarding the acquisition of the Company or its assets by merger or otherwise or , except as required by Law, Regulation or Order, engage in negotiations with, or disclose any non-public information relating to the Company, or afford access to its properties, books or records to any Person that has made or, to the Knowledge of the Seller, may be considering making an acquisition proposal. 32 ARTICLE VII.

The representations and warranties contained in Sections 4.09 and 4.11 shall survive both the Closing and any investigation by the parties with respect thereto but shall terminate and be of no further force and effect on the second anniversary of the Closing. The representations and warranties contained in Section 4.12 shall survive the Closing and any investigation by the parties with respect thereto until the tenth anniversary of the Closing. The representations and warranties contained in Sections 3.02, 3.06, 4.02(a), 4.08(c) (except to the extent the representations and warranties set forth in such Section relate to the Palo Duro Pipeline), 4.16, 4.17 and 4.18 and the covenants and agreements contained in Sections 6.06, 6.07, 6.08, 6.10(a)-(f) and 6.14 shall survive both the Closing and any investigation by the parties with respect thereto until the expiration of the statute of limitations (including any and all periods of extension or tolling thereof) applicable to actions on written contracts.

Notwithstanding the foregoing, any such representation, warranty, covenant or agreement as to which a bona fide claim relating thereto is asserted in writing in accordance with Section 8.02 during such survival period shall, with respect only to such claim, survive such survival period. The covenants and agreements in this Article VIII shall survive the Closing and shall remain in full force and effect for such period as is necessary to resolve any bona fide claim made with respect to any representation, warranty, covenant or agreement contained in this Agreement during the survival period thereof. The remaining covenants and agreements of the parties hereto contained in this Agreement shall survive the Closing without any contractual limitation on the period of survival. Section 8.02. General Indemnification. (a) Subject to the limitations on survival contained in Section 8.01, if the transactions contemplated hereby to occur at the Closing are effected, each party hereto (the "Indemnifying Party") hereby agrees, from and after the Closing, to indemnify and hold harmless the other party hereto (the "Indemnified Party") against any losses, claims, damages or liabilities 35 ("Losses") which such Indemnified Party shall actually incur, to the extent that such Losses (or actions, suits or proceedings in respect thereof and any appeals therefrom ("Proceedings")) (other than any Losses subject to Section 8.03 herein): (i) arise out of or are based upon any allegation that any representation or warranty made herein in Article III, IV or V for the benefit of the Indemnified Party by the Indemnifying Party is untrue or has been breached in any respect; or (ii) arise out of or are based upon any allegation that any covenant or agreement made herein for the benefit of the Indemnified Party by the Indemnifying Party has not been performed in accordance with its terms; and will reimburse the Indemnified Party for any legal or other expenses reasonably incurred by it in connection with investigating or defending against any such Losses or Proceedings. Notwithstanding the foregoing, except for Losses resulting from breaches of Sections 3.02, 3.06, 4.02, 4.08(c) (to the extent the representations and warranties set forth in such Section relate to the Palo Duro Pipeline), 4.10, 4.18, 4.19, 5.08, 6.06, 6.09, 6.10 and 6.12, the Indemnifying Party shall (x) not be liable to the Indemnified Party under this Section for any Loss incurred by the Indemnified Party which does not exceed $500,000, and (y) be liable to the Indemnified Party under this Section only for the amount of Losses incurred by the Indemnified Party which exceed $10,000,000 in the aggregate; provided, however, that the amount of such Losses that are subject to indemnification hereunder shall not exceed the Final Purchase Price; and provided, further, that the Losses incurred by an Indemnified Party shall, for purposes of determining the threshold level thereof in accordance with this sentence and otherwise, be offset by (i) the amount of any such Losses incurred by the Indemnifying Party jointly and severally with the Indemnified Party to the extent of payments made by the Indemnifying Party; and (ii) the proceeds of any insurance received by the Indemnified Party with respect thereto. (b) Promptly after receipt by the Indemnified Party under subsection (a) of this Section of notice of a Loss or the commencement of any Proceeding against which it believes it is indemnified under this Section, the Indemnified Party shall, if a claim in respect thereto is to be made against the Indemnifying Party under this Section, notify the Indemnifying Party in writing of the commencement thereof; provided, however, that the omission so to notify the Indemnifying Party shall not relieve it from any liability which it may have to the Indemnified Party to the extent that the Indemnifying Party is not prejudiced by such omission. (c) For purposes of determining whether an event, fact or occurrence constitutes a misrepresentation or a breach of any representation, warranty, covenant or agreement contained in this Agreement for which indemnification can be or is sought under this Section, as used in any such representation, warranty, covenant or agreement, the terms "Material" and "Material Adverse Effect" shall have the following meanings: "Material" shall mean material to the condition (financial and other), results of operations or business of a specified Person and its subsidiaries, if any, 36 taken as whole; provided that, without limiting the foregoing definition, the parties acknowledge and agree that any amount exceeding $500,000 is material; and "Material Adverse Effect" shall mean any change or effect that would be materially adverse to the consolidated business, condition (financial or otherwise), operations, performance or properties of a specified Person and its subsidiaries, if any, taken as a whole; provided that, without limiting the foregoing definition, the parties acknowledge and agree that any amount exceeding $5,000,000 is material in respect of Section 4.05 and that any amount exceeding $500,000 is material in all other cases; provided that the special purpose use of the terms "Material" and "Material Adverse Effect" in this subsection (c) shall be disregarded and given no effect in determining what is "material" for purposes of the definitions of such terms contained in Annex A to this Agreement and how they are used elsewhere in this Agreement. (d) The Indemnifying Party shall, within thirty (30) days after receipt of a notice of Loss or Proceeding given pursuant to subsection (b) of this Section, either acknowledge liability, as between the Indemnifying Party and the Indemnified Party, for such Loss or the amount in controversy in such Proceeding and pay the Indemnified Party the amount of such Loss or the amount in controversy in such Proceeding in cash or other immediately available funds (or establish by agreement with the Indemnified Party an alternative payment schedule), acknowledge liability, as between the Indemnifying Party and the Indemnified Party, for such Loss or the amount in controversy in such Proceeding, disavow the validity of the Loss or Proceeding or the amount thereof and, to the extent that it shall so desire in accordance with subsection (d) of this Section, assume the legal defense thereof, or object (or reserve the right to object until additional information is obtained) to the claim for indemnification or the amount thereof, setting forth the grounds therefor in reasonable detail; provided that, if the Indemnifying Party objects (or reserves its right to object) within such 30- day period as provided in this clause (iii), then the Indemnified Party may bring suit (in the same Proceeding or otherwise) to resolve the dispute and, pending final resolution of such dispute, the Indemnified Party may proceed as though the Indemnifying Party had responded in accordance with clause (i) above. If the Indemnifying Party does not respond to the Indemnified Party as provided in this subsection within such 30- day period, the Indemnifying Party shall be deemed to have acknowledged its liability for such indemnification claim in accordance with clause (i) of this subsection and the Indemnified Party may exercise any and all of its rights under applicable law to collect such amount. (e) If any such Proceeding shall be brought against an Indemnified Party and it shall notify the Indemnifying Party thereof in accordance with subsection (c) of this Section, the Indemnifying Party shall, if it shall have responded to such notice in accordance with clause (ii) of subsection (c) of this Section, be entitled to assume the legal defense thereof with counsel reasonably satisfactory to the Indemnified Party. After notice from the Indemnifying Party to the Indemnified Party of its election to assume the defense of such claim or such action, 37 the Indemnifying Party shall not be liable to the Indemnified Party under this Section for any attorney's fees or other expenses (except reasonable costs of investigation) subsequently incurred by the Indemnified Party in connection with the defense thereof. If the Indemnifying Party does not assume the defense of a Proceeding as to which it has acknowledged liability, as between itself and the Indemnified Party, pursuant to clause (ii) of subsection (c) of this Section, the Indemnified Party may require the Indemnifying Party to reimburse it on a current basis for its reasonable expenses of investigation, reasonable attorney's fees and expenses and reasonable out-of-pocket expenses incurred in the defense thereof and, subject to the provisions of subsection (e) of this Section, the Indemnifying Party shall be bound by the result obtained with respect thereto by the Indemnified Party. (f) An Indemnifying Party will not, without the prior written consent of the Indemnified Party (which consent shall not be unreasonably withheld), settle or compromise or consent to the entry of any judgment with respect to any pending or threatened Proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the Indemnified Party is an actual or potential party to such Proceeding) unless such settlement, compromise or consent includes an unconditional release of the Indemnified Party from all liability arising out of such Proceeding. If the Indemnifying Party has responded to the Indemnified Party pursuant to clause (i) of subsection (c) of this Section, the Indemnified Party may settle or compromise or consent to the entry of any judgment with respect to the Proceeding that was the subject of notice to the Indemnifying Party pursuant to subsection (c) of this Section without the consent of the Indemnifying Party. An Indemnified Party will not otherwise, without the prior written consent of the Indemnifying Party (which consent shall not be unreasonably withheld), settle or compromise or consent to the entry of any judgment with respect to any pending or threatened Proceeding, but, if such Proceeding is settled or compromised or if there is entered any judgment with respect to any such Proceeding, in either case with the consent of the Indemnifying Party, or if there be a final judgment of the plaintiff in any such Proceeding, the Indemnifying Party agrees to indemnify and hold harmless any Indemnified Party from and against any loss or liability by reason of such settlement, compromise or judgment. (g) From and after the Closing, except as provided in Section 8.03, the provisions of this Section shall be the sole and exclusive remedy of each party hereto for any breach of the other party's representations, warranties, covenants or agreements contained in this Agreement; provided, however, that each party may seek specific performance by the other party of the agreements and obligations set forth in Sections 6.07, 6.13 and 6.14. Notwithstanding anything in this Agreement to the contrary, in no event shall any losses, claims, damages or liabilities indemnified hereunder include any consequential or punitive damages, except to the extent that such are awarded to a third party in a proceeding against an indemnified party. 38 Section 8.03. Tax Indemnification and Audits. (a) From and after the Closing, the Seller hereby agrees to protect, defend, indemnify and hold harmless the Purchaser and the Company and its subsidiaries from and against, and agrees to pay, all: (i) Taxes of the Company or any subsidiary of the Company attributable to any Pre-Closing Taxable Period (except for Taxes arising out of any transaction of the Company or its subsidiaries not in the ordinary course of business occurring on the Closing Date but subsequent to the Closing), but only to the extent the amount of such Taxes exceeds the amount taken into account as a liability for such Taxes in determining the Purchase Price; (ii) Taxes of any corporation (other than the Company and its subsidiaries) that is or was a member of the Seller's Group; and (iii) Taxes of the Company or any subsidiary of the Company attributable to the Section 338(h)(10) Elections made pursuant to Section 8.04. (b) From and after the Closing, the Purchaser agrees to protect, defend, indemnify and hold harmless the Seller from and against, and agrees to pay, all: (i) Taxes of the Company or any subsidiary of the Company attributable to any Post-Closing Taxable Period; and (ii) Taxes arising out of any transaction of the Company or its subsidiaries not in the ordinary course of business occurring on the Closing Date and after the Closing. (c) If a claim shall be made by any taxing authority that, if successful, would result in the indemnification of a party (the "Tax Indemnified Party") under this Section, the Tax Indemnified Party shall promptly notify the party (the "Tax Indemnifying Party") obligated under this Section to indemnify the Tax Indemnified Party in writing of such fact; provided, however, that the omission to so notify the Indemnifying Party shall not relieve it from any liability which it may have to the Indemnified Party to the extent that the Indemnifying Party is not prejudiced by such omission. (i) The Tax Indemnified Party shall take such action in connection with contesting such claim as the Tax Indemnifying Party shall request in writing from time to time, including the selection of counsel and experts and the execution of powers of attorney; provided that (a) within thirty (30) days after the notice required by this subsection has been delivered (or such earlier date that any payment of Taxes is due by the Tax Indemnified Party but in no event sooner than five (5) days after the Tax Indemnifying Party's receipt of such notice), the Tax Indemnifying Party requests that such claim be contested, and (b) the Tax Indemnifying Party shall have agreed to pay to the Tax 39 Indemnified Party all costs and expenses that the Tax Indemnified Party incurs in connection with contesting such claim, including reasonable attorneys' and accountants' fees and disbursements. The Tax Indemnified Party shall not make any payment of such claim for at least thirty (30) days (or such shorter period as may be required by applicable law) after the giving of the notice required by this subsection, shall give to the Tax Indemnifying Party any information requested relating to such claim, and otherwise shall cooperate with the Tax Indemnifying Party in order to contest effectively any such claim. The Tax Indemnifying Party shall determine the method of any contest of such claim and shall control the conduct thereof. (ii) Subject to the provisions of paragraph (i) of this subsection, the Tax Indemnified Party shall enter into a settlement of such contest with the applicable taxing authority or prosecute such contest to a determination in a Court, all as the Tax Indemnifying Party may request. (iii) Promptly after the extent of the liability of the Tax Indemnified Party with respect to a claim shall be established by the final judgment or decree of a Court or a final and binding settlement with a Governmental Authority having jurisdiction thereof, the Tax Indemnifying Party shall pay to the Tax Indemnified Party the amount of any Taxes to which the Tax Indemnified Party may become entitled by reason of the provisions of this Section. (d) Notwithstanding anything to the contrary in this Section, any interest, penalties, fines, assessments or additions to Tax resulting from or attributable to the failure of the Tax Indemnified Party to act in a timely manner, including in filing Tax Returns, responding to Tax audit or other inquiries or making payments shall not be indemnifiable hereunder and shall be the sole responsibility of the Tax Indemnified Party. (e) In addition to the provisions of this subsection (c) of this Section, if any proposed audit adjustments of a Pre-Closing Taxable Period Tax Return could result in a tax adjustment for a Post-Closing Taxable Period, the Seller shall promptly inform the Purchaser. If the Seller elects not to contest the adjustment, the Purchaser shall have the option, at the Purchaser's own expense, to contest the proposed adjustment in accordance with the provisions of subsection (c) of this Section. (f) In addition to the provisions of subsection (c) of this Section, if any proposed audit adjustments of a Post-Closing Taxable Period Tax Return could result in an audit adjustment for a Pre-Closing Taxable Period, the Purchaser shall promptly inform the Seller. If the Purchaser elects not to contest the adjustment, the Seller shall have the option, at the Seller's own expense, to contest the proposed adjustment in accordance with the provisions of subsection (c) of this Section. (g) Except for the indemnification provided in Section 8.02 for breach of any representation or warranty contained in Section 4.10 or any covenant or agreement contained in Section 6.06, the indemnification provided in this Section shall be the sole remedy for any claim in respect of Taxes. In the event of a conflict between the provisions of this Section and any other provisions of this Agreement, the provisions of this Section shall control. 40 The limitations of Section 8.02 shall not apply to any amounts for which a party is liable under this Section. Any claim for indemnity under this Section must be made prior to the expiration of the applicable Tax statute of limitations with respect to the relevant taxable period (including all periods of tolling or extension). (h) To the extent any determination of Taxes, whether as the result of an audit or examination, a claim for refund, the filing of an amended return or otherwise results in a refund of Taxes paid (a "Refund"), the Seller shall be entitled to any part of such Refund attributable to a Pre-Closing Taxable Period, the Purchaser shall be entitled to any part of such Refund attributable to a Post-Closing Taxable Period, and the Purchaser and the Seller shall each be entitled to a Refund attributable to a taxable period described in Section 6.06(b) in the portions that the Purchaser and the Seller originally bore any Taxes payable with respect to such taxable period. Whichever party receives such Refund shall, within ten (10) days after receipt thereof, pay such Refund, or any part thereof, and the interest received thereon to the party entitled thereto under this subsection. (i) Any payment from the Purchaser to the Seller pursuant to Section 6.06 or this Section shall be treated for Tax purposes as an increase in the Purchase Price, and any payment from the Seller to the Purchaser pursuant to Section 6.06 or this Section shall be treated for Tax purposes as a reduction in the Purchase Price. Section 8.04. Section 338(h)(10) Elections. (a) The Seller, as the common parent of the Seller's Group, and the Purchaser shall make a joint election under section 338(h)(10) of the Code and a similar election under any applicable state income tax law for the Company and for each of the corporate subsidiaries (collectively, the "Section 338(h)(10) Elections"). At the Closing, the Seller shall deliver to the Purchaser an Internal Revenue Service Form 8023-A and any similar form under applicable state income tax law (the "Forms") with respect to the Section 338(h)(10) Elections, which shall have been duly executed by an authorized person for the Seller. The Purchaser shall cause the Forms to be duly executed by an authorized person for the Purchaser, shall complete any schedules required to be attached thereto, shall provide a copy of the executed Forms and schedules to the Seller, and the Seller and the Purchaser shall duly and timely file the Forms as prescribed by Treasury Regulation 1.338(h)(10)-1 or the corresponding provisions of applicable state income tax law. (b) The Purchaser shall select a firm of qualified appraisers to conduct an appraisal of the Company's assets (the "Appraisal"), which selection must be approved by the Seller, such approval not to be unreasonably withheld. The Seller and the Purchaser agree that the results of the Appraisal shall be used to allocate the Purchase Price and liabilities of the Company and its subsidiaries (plus other relevant items) to the assets of the Company and its subsidiaries for all purposes (including United States or any state, county or local government Tax purposes) in accordance with the Code and applicable Treasury Regulations. Such allocation of the Purchase Price shall be prepared by the Purchaser and submitted in writing to the Seller within ninety (90) calendar days after the date on which the Final Purchase Price is determined. The Seller shall consent to such Purchase 41 Price allocation unless such Purchase Price allocation is unreasonable. If the Seller does not object in writing to such proposed allocation within thirty (30) calendar days after receipt of the Purchaser's written proposal, the Purchaser's proposed allocation shall become final and binding on the Seller and the Purchaser. If the Seller makes timely objection to the Purchaser's proposal, the Purchaser and Seller shall have thirty (30) calendar days to reach agreement or the allocation shall be submitted to Price Waterhouse L.L.P. The determination of Price Waterhouse L.L.P. shall be final and binding on the Purchaser and the Seller and the fees and expenses of Price Waterhouse L.L.P. shall be borne equally by the Purchaser and the Seller. Price Waterhouse L.L.P. shall adjust the Purchase Price allocation provided by the Purchaser to the extent necessary to make such allocation reasonable. The Purchaser and the Seller shall duly prepare and timely file such reports and information returns as may be required under the Code and applicable Treasury Regulations and any corresponding or comparable provisions of applicable state and local Tax laws to report the allocation of the Purchase Price. ARTICLE IX. TERMINATION Section 9.01. Termination. This Agreement may be terminated at any time prior to the Closing: (a) by mutual consent of the Seller and the Purchaser; (b) by the Purchaser, upon a breach in any material respect of any representation, warranty, covenant or agreement on the part of the Seller set forth in this Agreement, or if any representation or warranty of the Seller shall have become untrue in any material respect, in either case such that the conditions set forth in Section 7.02(a) or Section 7.02(b), as the case may be, would be incapable of being satisfied by June 30, 1996 (or as otherwise extended as described in Section 9.01(e)); provided, however, that, in any case, a willful breach shall be deemed to cause such conditions to be incapable of being satisfied for purposes of this subsection; (c) by the Seller, upon a breach in any material respect of any representation, warranty, covenant or agreement on the part of the Purchaser set forth in this Agreement, or if any representation or warranty of the Purchaser shall have become untrue in any material respect, in either case such that the conditions set forth in Section 7.03(a) or Section 7.03(b), as the case may be, would be incapable of being satisfied by June 30, 1996 (or as otherwise extended as described in Section 9.01(e)); provided, however, that, in any case, a willful breach shall be deemed to cause such conditions to be incapable of being satisfied for purposes of this subsection (c); (d) by either the Seller or the Purchaser, if there shall be any Order which is final and nonappealable preventing the consummation of the transactions contemplated hereby, unless the party relying on such Order to terminate this Agreement has not complied with its obligations under Section 6.04(b); and 42 (e) by either the Seller or the Purchaser, if the Closing shall not have occurred prior to June 30, 1996; provided, however, that this Agreement may be extended by written notice from either party hereto to the other to a date not later than July 31, 1996, if the Closing shall not have occurred as a direct result of the nonfulfillment of the condition contained in subsection (a) of Section 7.01 by June 30, 1996.
