Seller may cure any such Casualty Loss by repairing it, or in the case of personal property or fixtures, replacing the assets or properties affected with equivalent items; provided if Seller is curing such Casualty Loss after the Closing Date, Seller will use its reasonable best efforts not to interrupt the business or operations of the LIG Companies. Following notice of the Casualty Loss, in the event Seller notifies Buyer in writing that it will not undertake the repair of the Casualty Loss (such notice to be provided within ten (10) Business Days of the event) or upon written notice from Buyer or Seller if Seller does not adequately cure any Casualty Loss that it elected to cure, the parties will promptly meet and attempt to agree upon the Value Impact reasonably expected. If the Buyer and Sellers cannot agree on the Value Impact of the Casualty Loss within ten (10) Business Days (or such other period as the Buyer and Sellers agree) of Buyer receiving notice of the Casualty Loss, then the Neutral Auditor (which shall be required to employ appraisers knowledgeable on the subject matter of the Casualty Loss to assist in determining the Value Impact) shall determine the Value Impact within fifteen (15) Business Days of receiving such notice. Seller shall provide the Neutral Auditor with such details of the Casualty Loss as the Neutral Auditor may reasonably require. All fees and expenses relating to the work, if any, to be performed by the Neutral Auditor shall be borne 50% by Seller and 50% by Buyer. Except as provided in the preceding sentence, all other costs and expenses incurred by the parties in connection with resolving any dispute hereunder before the Neutral Auditor shall be borne by the party incurring such cost and expense. The parties shall instruct the Neutral Auditor to render its reasoned written decision as soon as practicable but no later than forty-five (45) days after its engagement. The Neutral Auditor's decision shall be set forth on a written statement delivered to Seller and Buyer and shall be final, binding, conclusive and non-appealable for all purposes hereunder. The purchase price payable pursuant to Section 2.1 shall then be adjusted in accordance with the determination made in accordance with this Section 2.2(a)(ii).

(b) Adjustment Methodology. All such calculations shall be made in accordance with GAAP, applied in a manner consistent with the calculation and valuation methodologies set forth on Schedule 2.2.

(i) Within ninety (90) days after the Closing Date, Seller shall prepare and deliver to Buyer a statement (the "Adjustment Statement") which shall set forth Seller's calculation, as of the close of business (Houston, Texas time) on the last day of the month immediately preceding the Closing Date, of: (i) LIG Net Working Capital ("Closing LIG Net Working Capital") (ii) Exchange Imbalances ("Closing Exchange Imbalances") (iii) LIG Inventory ("Closing LIG Inventory") and the value thereof in each case, calculated in accordance with Schedule 2.2. The Adjustment Statement shall be prepared by Seller based upon the same accounting and valuation methodologies employed by Seller in calculating Estimated LIG Net Working Capital, Estimated Exchange Imbalances and Estimated LIG Inventory respectively, provided that any accounts receivable for which payment has not been received will be excluded in calculating Closing LIG Working Capital (except to the extent there were allowances for such accounts in Current LIG Assets or such accounts or portions thereof were already excluded from the calculation of Current LIG Assets).

Buyer shall provide Seller and its independent accountants and financial advisors, at no expense to Seller, with reasonable access during normal business hours to the working papers, accounting and other books and records of the Business related to the matters to be adjusted hereunder and the appropriate personnel of the Business to the extent reasonably required to complete their preparation of the Adjustment Statements. Buyer shall also ensure that the employees of the Business (to the extent employed by Buyer) previously involved with the foregoing accounting services will perform their customary and usual monthly tasks, including the month end closing of the books and records of the Business, during the periods following the Closing Date for purposes of the foregoing.

(ii) After receipt of the Adjustment Statement, Buyer shall have thirty (30) days to review the Adjustment Statement. On or prior to the 30^th day after receipt of the Adjustment Statement, Buyer shall deliver written notice to Seller specifying in reasonable detail any disputed items and the basis therefore. If Buyer fails to so notify Seller of any disputes regarding the Adjustment Statement on or prior to the 30^th day after receipt of the Adjustment Statement, all calculations and valuations of Closing LIG Net Working Capital, Closing Exchange Imbalances and Closing LIG Inventory set forth on the Adjustment Statement shall be deemed accepted by Buyer and shall be final, binding, conclusive and nonappealable for all purposes of this Agreement. If Seller fails to deliver the Adjustment Statement to Buyer within the time provided in Section 2.2(c)(i), Buyer may prepare the Adjustment Statement and deliver it to Seller, in which case Seller will have thirty (30) days to object to it as provided in this clause (ii), failing which, it will be final, binding, conclusive and nonappeable for all purposes under this Agreement.

(iii) If Buyer so notifies Seller (or if Seller notifies Buyer, if applicable) of any disputed items on the Adjustment Statement in accordance with the above provisions, Seller, on the one hand, and Buyer, on the other, shall, over the 20 days following the date of such notice (the "Resolution Period"), attempt to resolve their differences and any written resolution by them as to any disputed item shall be final, binding, conclusive and nonappealable for all purposes of this Agreement. If at the conclusion of the Resolution Period, Seller, on the one hand, and Buyer, on the other, have not reached an agreement on the disputed items, then all items remaining in dispute shall be submitted by Seller and Buyer to the Chicago office of PricewaterhouseCoopers LLP (the "Neutral Auditor"). All fees and expenses relating to the work, if any, to be performed by the Neutral Auditor shall be borne 50% by Seller and 50% by Buyer. Except as provided in the preceding sentence, all other costs and expenses incurred by the parties in connection with resolving any dispute hereunder before the Neutral Auditor shall be borne by the party incurring such cost and expense. The Neutral Auditor shall act as an arbitrator to determine only those items still in dispute at the end of the Resolution Period. In no event shall the Neutral Auditor's determination be outside of the range of amounts claimed by the respective parties with respect to those items in dispute. The parties shall instruct the Neutral Auditor to render its reasoned written decision as soon as practicable but in no event later than forty-five (45) days after its engagement (which engagement shall be made no later than ten Business Days after the end of the Resolution Period). Such decision shall be set forth in a written statement delivered to Seller and Buyer and shall be final, binding, conclusive and nonappealable for all purposes hereunder. The term "Final Adjustment Statement" shall mean the definitive Adjustment Statement agreed to by Seller and Buyer in accordance with Section 2.2(c)(ii) or the definitive Adjustment Statement resulting from the determination made by the Neutral Auditor in accordance with this Section 2.2(c)(iii), in each case setting forth the final determination of Closing LIG Net Working Capital ("Final LIG Net Working Capital"), Closing Exchange Imbalances ("Final Exchange Imbalances") and Closing LIG Inventory ("Final LIG Inventory").

(iv) In the event (A) Final LIG Net Working Capital is greater than Estimated LIG Net Working Capital, Buyer shall pay to Seller an amount equal to such excess or (B) Final LIG Net

Working Capital is less than the Estimated LIG Net Working Capital, Seller shall pay to Buyer an amount equal to such deficiency. In the event (C) Final Exchange Imbalances is greater than Estimated Exchange Imbalances, Buyer shall pay to Seller an amount equal to the value (calculated in accordance with Schedule 2.2) of such excess or (D) Final Exchange Imbalances is less than Estimated Exchange Imbalances, Seller shall pay to Buyer an amount equal to the value (calculated in accordance with Schedule 2.2) of such deficiency. In the event (E) Final LIG Inventory is greater than Estimated LIG Inventory, Buyer shall pay to Seller an amount equal to the value (calculated in accordance with Schedule 2.2) of such excess or (F) Final LIG Inventory is less than Estimated LIG Inventory, Seller shall pay to Buyer an amount equal to the value (calculated in accordance with Schedule 2.2) of such deficiency. Buyer and Seller shall aggregate or offset, as the case may be, any amounts required to be paid pursuant to the three immediately preceding sentences of this Section 2.2(c)(iv) so that only one such payment is made. Any such payment required pursuant to this Section 2.2(c)(iv) (the "Adjustment Amount") shall be made by wire transfer of immediately available funds to the account designated by Seller or Buyer, as the case may be, in United States Dollars, within five (5) Business Days after (X) the Adjustment Statement has been accepted or deemed accepted by Buyer or Seller pursuant to Section 2.2(c)(ii), (Y) any proposed change made by Buyer or Seller has been agreed upon by the parties during the Resolution Period or (Z) a final determination has been made by the Neutral Auditor as described in Section 2.2(c)(iii). Payments due shall be paid to the applicable party together with interest at the Interest Rate from and including the Closing Date to but excluding the date of payment.

(v) The parties hereby acknowledge and agree that any receivables that are not included as Current LIG Assets will be assigned to Seller so that Seller may pursue the recovery of such amounts.

Section 2.3. Closing. Unless this Agreement shall have been terminated and the transactions contemplated hereby shall have been abandoned pursuant to Article VIII hereof, the closing of the transactions contemplated by this Agreement (the "Closing") shall take place at the offices of Seller located at 1201 Louisiana Street, Suite 1200, Houston, Texas, at 10:00 a.m., Houston, Texas time, on April 1, 2004 if all of the conditions to the Closing set forth in Article VII hereof are satisfied or waived, or the first Business Day of the first calendar month that is not less than two Business Days after all of the conditions to the Closing set forth in Article VII hereof are satisfied or waived (other than those that by their terms cannot be satisfied prior to the Closing), or such other date, time and place as shall be agreed upon by Seller and Buyer (the actual date and time of the Closing the "Closing Date").

As soon as practicable after the date of execution of this Agreement, but not later than twenty (20) business days prior to the Closing Date, Buyer shall extend offers of employment or continued employment, as the case may be, to not less than seventy-five percent (75%) of the Current LIG Employees. Each such offer by Buyer will be effective as of the Closing Date and shall include terms consistent with Section 6.6(c) ("Offer of Employment"). Each such individual who accepts Buyer's Offer of Employment within the time period specified by Buyer in its Offer of Employment (which shall in all cases be at least five business days unless Seller otherwise agrees in writing) and who remains a Current LIG Employee (active or inactive) through the Closing Date, shall be referred to as a "Transferred Employee." Each LIG Employee who is not a Transferred Employee shall be referred to as a "Non-Transferred Employee." Prior to the Closing Date, Seller shall take, or shall cause to be taken, such action as is necessary such that all Non-Transferred Employees shall have ceased to be employees of the LIG Companies on or prior to the Closing Date, which may include transferring the employment of such persons to Seller or one of its Affiliates.

(ii) Seller shall retain liability and responsibility for the payment of severance benefits (if any) incurred on or prior to the Closing Date as a result of such Offers of Employment or incurred as a result of such termination or transfer of employment from the LIG Companies on or prior to the Closing Date as described above; provided, that Buyer shall indemnify and hold Seller harmless against such severance liabilities to Current LIG Employees the extent they exceed actual payment of one million two hundred and fifty thousand dollars ($1,250,000) in the aggregate; provided that, in determining the aggregate severance liabilities, there shall be disregarded (and such liabilities shall be Seller's sole liability and responsibility) any such severance liabilities or payments to (X) any employee who received an Offer of Employment, (Y) any employee who voluntarily

terminated his or her employment prior to Closing and (Z) any employee who continues in the employ of Seller or any of its Affiliates after Closing; provided further that, in no event will Buyer be liable for more than $1,250,000 of such severance liabilities and any additional severance liabilities will be the sole liability and responsibility of Seller. In the event that any Current LIG Employee makes a discrimination-based claim in respect of any decision by Buyer not to make any Offer of Employment to any Current LIG Employee, Buyer will defend and indemnify Seller against any such claim.

(b) Access to Personnel. In furtherance of the provisions of Section 6.6(a) above, Buyer and Seller will agree promptly after the date hereof upon the procedures by which the Current LIG Employees who will receive an Offer of Employment will be identified, and by which Current LIG Employees designated by Buyer may be made reasonably available to be interviewed by Buyer during normal business hours. Also in furtherance of the foregoing provisions of Section 6.6(a), and subject to any applicable laws, Seller and the LIG Companies will afford Buyer reasonable access during normal business hours following prior written notice to Seller and the LIG Companies to review the personnel files, performance evaluations and other relevant employee records of the LIG Companies.

(c) Post-Closing Benefits; Service Credit for Transferred Employees. For a period of not less than 12 months immediately following the Closing Date, Buyer will provide, or will cause the LIG Companies to provide, Transferred Employees with salaries and wage levels that are no less favorable than the salaries and wage levels of such Transferred Employees immediately prior to the Closing Date, but not in excess of the compensation with respect to such Transferred Employee in the schedules disclosed to Buyer pursuant to Section 6.1(d), and will provide Transferred Employees with benefits levels that are no less favorable than similarly situated employees of Buyer and its Affiliates and Subsidiaries immediately prior to the Closing Date or as subsequently modified for all such similarly situated employees; provided that during 12-month period following the Closing Date, any Transferred Employee whose employment is terminated by Buyer, the LIG Companies or any of their Affiliates, for any reason other than for "cause," shall be entitled to receive from Buyer, one of the LIG Companies or an Affiliate, as applicable, the cash severance amount set forth with respect to such Transferred Employee on Schedule 6.1(d). Nothing in the foregoing shall be construed as requiring Buyer or any LIG Company to continue to employ the Transferred Employees for a 12 month period following the Closing Date, or to continue to provide such salaries, wage levels and benefit levels on an active-employee basis following termination of employment to any Transferred Employee whose employment with Buyer or any LIG Company terminates during such 12 month period. With regard to Buyer's current employee benefit plans, all of which are listed on Schedule 6.6(c) attached hereto, each Transferred Employee shall be eligible to participate in each defined contribution plan listed on such schedule on the first day of the fiscal quarter coincident with or next following the Closing Date and will receive full service credit for vesting purposes for any periods of service completed with Seller, any LIG Company and their respective Affiliates to the same extent such Transferred Employee's service was recognized under the defined contribution plan in which such Transferred Employee participated or was eligible to participate immediately prior to the Closing Date. With regard to Buyer's employee benefit plans identified on Schedule 6.6(c) as welfare plans, each Transferred Employee will be eligible to participate in such plans on the Closing Date, or, if the Closing Date is not on the first day of a calendar month, each Transferred Employee will be eligible for participation in such plan on the first day of the calendar month next following the Closing, subject, however, to such Transferred Employee satisfying the eligibility requirements of such plans and related insurance policies (e.g., actively-at-work requirements). Buyer shall provide, or shall cause the LIG Companies to provide, each Transferred Employee with credit for any deductible amounts and out-of-pocket expenses paid prior to the Closing Date in satisfying a like amount of any deductible amount (but not any out-of-pocket maximums) which would otherwise apply from the Closing Date through December 31, 2004, under any comparable type of welfare plan in which such Transferred Employee participates on or after the Closing Date, subject to verification of the payment of such amounts by the Transferred Employee. With regard to Buyer's

employee benefit plans identified on Schedule 6.6(c) as a nonqualified plan, Transferred Employees will be treated as new employees of Buyer. With regard to vacation allowances, Transferred Employees shall be eligible to begin accruing vacation benefits as of the Closing Date, and Buyer shall provide, or shall cause the LIG Companies to provide, credit for each Transferred Employee's service with Seller, any LIG Company and their respective Affiliates to the same extent as such service was recognized by each of them immediately prior to the Closing Date, provided that the number of vacation days to which each Transferred Employee will be entitled following the closing Date shall be determined exclusively under Buyer's vacation policies and Buyer will not provide any credit or compensation for unused vacation days accumulated with Seller, any LIG Company or their respective Affiliates. Any liability for vacation days, hours or other vacation allowances accrued by Transferred Employees prior to the Closing Date shall be the responsibility of Seller. With regard to any other employee benefit plans of the Buyer or its Affiliates, Transferred Employees will receive credit for service on the same basis as other, similarly situated employees of Buyer or its Affiliates.

(d) COBRA. Buyer shall provide, or shall cause the LIG Companies to provide, continuation health care coverage to Transferred Employees and their qualified beneficiaries who incur or incurred a qualifying event, in accordance with the continuation health care coverage requirements of Section 4980B of the Code and Title I, Subtitle B, Part 6 of ERISA ("COBRA"), after the Closing Date or, if later, the date the Transferred Employees actually commence participation in Buyer's group medical plan. Seller shall be responsible for any COBRA healthcare continuation claims of Non-Transferred Employees, any Transferred Employees until such employees actually become covered under the Buyer's group medical plan or, if earlier, until such coverage earlier terminates in accordance with applicable Law and the terms of the Benefit Plan, and any former employees or other persons (other than Transferred Employees) who were entitled to COBRA rights under the Benefit Plans on or prior to the Closing Date.

(e) Seller Plans. Before Closing, Sellers will, and will cause the LIG Companies, to (i) terminate all Benefit Plans that are sponsored, contributed to, maintained, or entered into solely by an LIG Company, unless sponsorship is transferred to and assumed by Seller prior to the Closing, and (ii) terminate the LIG Companies participation in any Benefit Plans, and effective as of the applicable date, LIG Employees shall cease to participate in the applicable Benefit Plan, and from and after the applicable date, LIG Employees shall cease to be eligible to accrue further benefits under the applicable Benefit Plan. Seller shall be solely responsible for winding up any such Benefit Plans. No assets or liabilities arising under any such Benefit Plan are assumed by Buyer.

Section 6.7. WARN Notices. Any workforce reductions carried out following the Closing Date by Buyer or any of the LIG Companies or their respective Subsidiaries shall be done in accordance with all applicable Laws governing the employment relationship and termination thereof including the Worker Adjustment and Retraining Notification Act ("WARN") and regulations promulgated thereunder, and any comparable state or local Law. Seller shall be responsible for all obligations, if any, under WARN or equivalent state statutes and any applicable regulations thereunder with respect to the employment terminations prior to or on the Closing Date.

Section 6.8. Non-Solicitation. Until the Closing shall actually have occurred, Buyer acknowledges that it remains subject to paragraph 7 of the Confidentiality Agreement.

Section 6.9. Guarantees. Buyer shall offer to cause itself or one or more of its Affiliates to be substituted in all respects for Seller or Affiliates of Seller, as the case may be, effective as of the Closing, in respect of all obligations of Seller or Affiliates of Seller, as the case may be, under each of the guarantees, indemnities, surety bonds, performance bonds, letters of credit and other credit support arrangements obtained by the Seller or Affiliates of Seller, as the case may be, for the benefit of the Business as identified on Schedule 6.9 (the "Guarantees"), and shall request Seller and all Affiliates of Seller (other than the LIG Companies) to be released, as of the Closing Date, from any and all

obligations under such Guarantees. If Buyer is unable to effect such a substitution with respect to any such Guaranty after using its reasonable best efforts to do so, the Buyer shall obtain letters of credit for the benefit of such third party from a nationally recognized banking institution, on terms substantially similar to the existing arrangement and from financial institutions reasonably satisfactory to the third party.

Section 6.10. No Shopping. From and after the date of this Agreement, neither Seller, its Affiliates nor any of their respective officers, directors, employees, representatives, agents or anyone acting on behalf of any of them shall, directly or indirectly, encourage, solicit, engage in discussions or negotiations with, or provide any non-public information to, any Person (other than Buyer, its Affiliates and their representatives) with respect to any merger, purchase or sale of assets, purchase or sale of equity interests or any similar transaction involving any of the LIG Companies or their assets unless this Agreement is terminated in accordance with Article VIII hereof.

Section 6.11. Funding of Disbursements. Effective at the opening of business on the Closing Date, Buyer shall be responsible for funding all disbursements of the Business.

Section 6.12. Transitional Use of Seller' Trademarks.

(a) Effective upon the Closing, Seller hereby grants to each of the LIG Companies, a limited, non-transferable, non-exclusive, royalty-free right and license to use the trademarks, service marks and trade names which are, in each case, in existence on the Closing Date, owned or licensed by Seller or their Affiliates other than the LIG Companies, currently being used in the conduct of the respective businesses of the LIG Companies and set forth on Schedule 6.12; provided, however, Buyer shall have no right to the use of "AEP", "American Electric Power" or any derivations thereof. Such license shall terminate 30 days following the Closing, and upon termination thereof, the LIG Companies' shall immediately discontinue the use of all such trademarks, service marks and trade names.

(b) Notwithstanding the above, Buyer shall have the free and unlimited use, royalty free and forever, of any and all trademarks, service marks or trade names which contain the words or characters "LIG" or "Louisiana Intrastate Gas", unless such trademark, service mark or trade name also contains the words or characters "AEP" or "American Electric Power." Seller agrees to execute any documents necessary to provide Buyer the rights set forth in this subparagraph (b), and neither Seller nor any of its Affiliates may use any names containing the characters "LIG" or words "Louisiana Intrastate Gas Corporation" after Closing.

Section 6.13. Intercompany Transactions. Regardless of whether any such agreement or arrangement will continue in effect after Closing as provided herein, effective as of the Closing and consistent with the calculation of LIG Net Working Capital, all intercompany receivables or payables and loans then existing between Seller and any Affiliates of Seller (other than between the LIG Companies), on the one hand, and any LIG Company, on the other, including each agreement and arrangement set forth on Schedule 4.17 shall be fully settled by making intercompany cash transfers so that there are no outstanding payables, receivables or other liabilities relating to such intercompany transactions for the period prior to Closing (it being understood that any future contractual obligations of the LIG Companies set forth on Schedule 6.13 that are to be performed after the Closing Date shall not be settled and shall continue in full force and effect). Except for those agreements and arrangements set forth in Schedule 6.13, prior to Closing, all agreements or arrangements set forth on Schedule 4.17 shall be terminated and the LIG Companies shall have no further obligations thereunder. The settlements and terminations required under this Section 6.13 shall all be accomplished (a) in the manner contemplated by this Agreement and (b) without any violation of any Law or the incurrence of any tax, penalties, interest or other charges (other than Taxes for which Seller is responsible).

Section 6.14. Payment of Indebtedness. At or prior to the Closing, Seller shall cause to be satisfied and cancelled with respect to the LIG Companies and cause the LIG Companies to be fully released from any obligations or indebtedness (except for capitalized leases reflected on the Financial

Statements) under any guaranty, loan agreement, mortgage, indenture, security agreement or other agreement, or other instrument, in each case relating to the borrowing of money by any LIG Company, and Seller shall remove, or cause to be removed, all Liens on the Shares under the Caddis Financing, and all other Liens pertaining to or affecting the LIG Companies or any of the assets thereof. Any payment that is made by or on behalf of a LIG Company pursuant to this Section 6.14 or Section 6.13, or other adjustment in legal rights that occurs pursuant thereto, shall not give rise to a reduction in Tax attributes under Section 108(b) of the Code with respect to such LIG Company.

Section 6.15. Transition Services Agreement. At the Closing, Buyer and Seller (or an Affiliate of Seller) shall execute and deliver a transition services agreement in the form attached hereto as Exhibit A (the "Transition Services Agreement").

Section 6.16. Resignations.

Section 6.18. Limited Covenant Not to Compete.

(a) From the Closing Date and for a period of two years thereafter, neither Seller nor any of its Affiliates shall (without the written consent of Buyer): (A) call upon any customer of any of the LIG Companies for the purpose of soliciting, diverting or intentionally enticing away the business of such person or entity from the LIG Companies; or (B) directly or indirectly, own, manage, control or operate, in the State of Louisiana, any pipeline system used for the transmission of natural gas on an intrastate basis for the account of third parties or any plant or facility used for the processing of natural gas for the account of third parties; provided, however, that this Section shall not apply to (1) the conduct of business pursuant to the arrangements between the Dow Chemical Company and its Affiliates and American Electric Power Company, Inc. and its Affiliates relating to the Plaquemine cogeneration facility (the "Plaquemine Cogen Project"); (2) the conduct of business by Jefferson Island Storage & Hub, L.L.C. (but such activities can not be undertaken if third-party pipeline or other facilities are utilized to conduct such business to deliver gas to industrial customers located on the Mississippi River corridor located between Baton Rouge and New Orleans, and (3) Seller and its Affiliates, including Jefferson Island Storage & Hub, L.L.C. (or any other person or entity to the extent they engage in such practices) as a result of a merger, acquisition, business combination or similar transaction consummated after the Closing Date by Seller or any of its Affiliates if such transaction is with an entity or involving a group of assets that is not primarily involved in the transmission of natural gas on an intrastate basis in Louisiana for the account of third parties or the ownership or operation of plants or facilities in Louisiana used for the processing of natural gas for the account of third parties (together, the "Restricted Acquisition Activity"); provided, further, however, that this Section 6.18(a) shall not apply to the purchaser or their successors of any of the membership interests, or the assets, of Jefferson Island Storage & Hub, L.L.C. or the Plaquemine Cogen Project. For purposes of this Section 6.18, an entity or group of assets shall be deemed to be "primarily involved in" the Restricted Acquisition Activity if it derives 75% or more of its gross revenues (measured for the prior twelve month period ending on the date of such transaction) from such Restricted Acquisition Activity.

(b) Seller agrees that from the Closing Date and for a period of 2 years thereafter, neither Seller nor any of its Affiliates shall make contact with any Transferred Employee who is at such time employed by any LIG Company for the purpose of soliciting such employee for hire or otherwise disrupting such employee's relationship with such LIG Company, as the case may be, or hire any such

employee whether as an employee or independent contractor and whether or not such engagement is solicited by Seller.

(c) From and after Closing, Seller shall not (and shall cause each of its Affiliates not to) disclose to any third party or use to the competitive disadvantage of Buyer or the LIG Companies, any proprietary or confidential information ("Confidential Information") related to the Business or the LIG Companies. Seller hereby assigns to the LIG Companies the benefit of and right to enforce all of the confidentiality agreements entered into by Seller or its Affiliates that are related to the sales process for the LIG Companies. If such Assignment is prohibited or would void such agreements, then upon request by Buyer, Seller will enforce such Agreements at Buyer's direction, request and expense.

Section 6.19. Financial Statements. As soon as practicable after the execution of this Agreement, a public accounting firm of Buyer's choice will perform at Buyer's sole expense an audit of the LIG Companies' financial statements for three years ending December 31, 2003 and timely quarterly review of the first quarters of 2003 and 2004. Seller agrees to use its reasonable efforts to facilitate (and shall cause the LIG Companies and any other of Seller's Affiliates to undertake reasonable efforts to facilitate) the completion of the audit by the Closing Date; provided that so long as Seller is in compliance, in all material respects, with the covenants set forth in this Section 6.19, the failure of accountants to perform such an audit or deliver such financial statements shall not delay the Closing Date. Seller consents to Buyer's engagement of Seller's and the LIG Companies' auditors to perform the audit, and agrees to sign a reasonable and customary representation letter to auditor.

Section 6.20. LIG Inventory. The term "LIG Inventory" means: (i) the quantity of natural gas in storage for the account of the LIG Companies as of the Closing Date at Seller's Jefferson Island Storage Facility and (ii) the quantity of natural gas and natural gas liquids and condensate in storage at company-owned storage facilities (and third party storage facilities identified on Schedule 6.20).

The measurement of LIG Inventory of natural gas liquids and condensate shall determine the quantity of such natural gas liquids or condensate in the storage tanks of the Placquemine Gas Plant, above the load line, and in the company-owned (and third party storage facilities identified on Schedule 6.20), if any, as of 7:00 a.m., central prevailing time on the Closing Date.

Section 6.21. TRC Arrangements. On or prior to the Closing Date, Seller and Buyer will use their respective reasonable best efforts to cause the TRC Arrangements to be legally separated between the LIG Companies, on the one hand, and Jefferson Island Storage & Hub, L.L.C., on the other hand, such that the LIG Companies are allocated no less than 80% (the "Minimum TRC Allocation") of the existing coverage amount under the TRC Arrangements and Buyer and its Affiliates are added as named insureds under the 2000 and 2003 American International Specialty Lines Insurance Company Policies that are included in the TRC Arrangements (the "AIG Policies"). In the event that the parties are unable to obtain such legal separation, Seller shall cause Buyer and its Affiliates to be Client Releasees (as defined in the Exit Strategy Agreement) under the Exit Strategy Agreement, and Seller shall consent and shall cause its Affiliates to consent to the addition of Buyer and its Affiliates as named insureds under the 2003 AIG Policy and will use its reasonable best efforts to add Buyer and its Affiliates as a named insured under the 2000 AIG Policy, and will use its reasonable best efforts so that the LIG Companies are allocated no less than the Minimum TRC Allocation of the existing coverage amount under the TRC Arrangements. If the separation of the TRC Arrangements is not accomplished by Seller prior to Closing, to the extent requested by Buyer after Closing, Seller will use its reasonable best efforts to cause such separation after Closing. The parties acknowledge and agree that American

Electric Power Company, Inc. and its Affiliates will continue to be named insureds on the policies underlying the TRC Arrangements. Buyer acknowledges and agrees that the purchaser of Jefferson Island Storage & Hub, L.L.C. shall also be a Client Releasee and named and/or additional insured, for its allocable share of the coverage amount under the TRC Arrangements.

Section 6.22. Properties Held By Affiliates. Schedule 6.22 sets forth a description of all property and assets (real, personal and intangible) that are used in the Business but not owned or leased by the LIG Companies (other than TRC Arrangements, which are the subject of 6.21, and software license agreements to which the LIG Companies are not a party and which are not transferable pursuant to their terms) (the "Affiliate Transfer Assets"), including the identity of the Affiliate holding such title, leasehold or other interest and the nature of such interest. Prior to Closing, Seller will cause each Affiliate holding the Affiliate Transfer Assets to transfer legal title to the fee-owned property to one or more LIG Companies determined by Buyer free and clear of all Liens, other than Permitted Liens. Notwithstanding the foregoing, to the extent Seller or its Affiliates are unable to cause the transfer of certain Affiliate Transfer Assets that are leased due to the failure to obtain the consent to such transfer from any third party, then Seller shall have no further obligation hereunder.

Section 6.23. Swap Transactions. Schedule 6.23 sets forth all of the fixed price gas sales commitments and the terms thereof ("Swaps") to which any LIG Company is a party or is bound and which will continue to be obligations of the LIG Companies after Closing. From and after Closing, Seller and the LIG Companies will settle each such Swap by the fifth business day of the month after the publication of the relevant gas price index as described below:

Contract E: Seller will pay to the LIG Companies (if the Inside FERC Henry Hub Index Settlement Price for the month is greater than $4.915) or receive from the LIG Companies (if the Inside FERC Henry Hub Index Settlement Price for the month is less than $4.915) the difference between the Inside FERC Henry Hub Index Settlement Price for the month indicated and $4.915 per MMBtu, multiplied by the volume attributable to such Swap for such month.

Contract V: Seller will pay to the LIG Companies (if the NYMEX Last Day Settlement Price is greater than $5.33 or $5.48 for the Swap so priced as set forth on Schedule 6.23) or receive from the LIG Companies (if the NYMEX Last Day Settlement Price is less than $5.33 or $5.48 for the Swap so priced as set forth on Schedule 6.23) the difference between the NYMEX Last Day Settlement Price for the month indicated and $5.33 per MMBtu and $5.48 per MMBtu for the Swap so priced as set forth on Schedule 6.23 (for April and May, 2004), multiplied by the volume attributable to each such Swap for such month.

Section 6.24. Contract Discount Adjustment. On the Closing Date, Seller will pay Buyer the aggregate present value of future discounted prices provided under Contract #SCFIT0001 for any months extending past the Closing Date. Both the monthly values and the discounted prices thereof and the normal settlement dates are set forth on Schedule 6.24. The amounts due (reflected as gross payment due Buyer on Schedule 6.24) will be discounted from the normal settlement date to the Closing Date using a five percent (5%) discount rate.

(ii) No reimbursement or payment for any Damages asserted against Seller under Section 9.2(a)(i) above shall be required unless and until the cumulative aggregate amount of such Damages equals or exceeds one and one-half percent (1.5%) of the Final Purchase Price (the "Seller's Threshold") and then only to the extent that the cumulative aggregate amount of Damages, as finally determined, exceeds the Seller's Threshold; provided that in calculating Seller's Threshold any Damages which individually total less than Fifty Thousand United States Dollars (US $50,000) each ("De Minimis Buyer Losses") shall be excluded in their entirety and Seller in any event shall have no liability hereunder to any Buyer Indemnified Parties for any such De Minimis Buyer Losses regardless of the status of the Seller's Threshold; provided further, that Damages totaling less than $50,000, but arising from or related to a common occurrence or related events will be aggregated and such aggregated amount shall not, if in excess of $50,000, be treated as a De Minimis Buyer Loss.

(iii) Seller shall not be liable for any Damages to the extent that Buyer collects such Damages under the Equitable Indemnity. Buyer is not obligated to file suit or undertake other legal action under Equitable Indemnity before seeking indemnity from Seller.

(iv) Seller's indemnification obligations set forth in Section 9.2(a)(iv) are subject to the additional limitations set forth below:

(A) Except with respect the indemnification obligations set forth in Section 9.2(a)(iv)(C), (i) Seller shall only be liable for Environmental Liabilities to the extent that a written claim is provided to Seller in a reasonably detailed written communication prior to the second anniversary of the Closing Date and Buyer shall afford the Seller a reasonable opportunity to

evaluate the conditions giving rise to such claim and (ii) Seller shall only be liable for breaches of the representations and warranties set forth in Section 4.14 to the extent that a written claim is provided to Seller in accordance with Section 9.1(b) prior to the end of the Survival Period; provided, that, if a claim under Section 9.2(a)(iv)(A) or (C) could also constitute a breach of a representation or warranty under Section 4.14, Buyer is not precluded from making after such Survival Period a claim under Section 9.2(a)(iv)(A) or (C) so long as Buyer is in compliance with the provisions and procedures for making such a claim under this Agreement.

(B) Except with respect to the indemnification obligations set forth in Section 9.2(a)(iv)(C), Seller shall not be liable for any Damages except to the extent that the aggregate amount of such Damages exceeds $800,000 (the "Environmental Indemnity Threshold") and then Seller shall only be liable for ²/3 of the next $5,000,000 in Damages (in excess of the Environmental Indemnity Threshold) and then 100% of Damages incurred in excess of $5,800,000 of Damages in the aggregate (the "Environmental Contribution Percentage") until the Environmental Indemnity Cap (as defined below).

(C) Except with respect the indemnification obligations set forth in Section 9.2(a)(iv)(C), Seller's indemnification obligation under Section 9.2(a)(iv) shall not exceed $6,000,000 (the "Environmental Indemnity Cap").

(D) Except with respect the indemnification obligations set forth in Section 9.2(a)(iv)(C), Seller shall not be liable for any Damages which individually total less than Fifty Thousand United States Dollars (US $50,000) each ("De Minimis Environmental Losses"). De Minimis Environmental Losses shall be excluded in their entirety from the Environmental Indemnity Threshold and Seller in any event shall have no liability hereunder to any Buyer Indemnified Party for any such De Minimis Environmental Losses regardless of the status of the Environmental Indemnity Threshold; provided, however, that Environmental Losses totaling less than $50,000, but arising from or related to a common occurrence or common circumstances, will be aggregated and such aggregated amount shall not, if in excess of $50,000, be treated as a De Minimis Environmental Loss.

(E) Seller shall not be responsible for any Damages that arise out of any action to meet a cleanup or remedial standard under Environmental Law that is more stringent or costly than necessary for the continued use of any property or facility as it was last used by any of the LIG Companies prior to the Closing Date under Environmental Laws applicable as of the Closing Date.

(F) Seller shall not be responsible for any costs of any post-Closing construction, demolition or renovation of any facilities owned, leased or operated by any of the LIG Companies including any asbestos abatement obligations arising from such activities.

(G) Seller shall not be liable for any Damages to the extent such Damages relate to or arise from any matter that is specifically subject to TRC Arrangements and to the extent actually paid or remediated thereunder and Buyer shall be obligated to pursue any recovery under such TRC Arrangements prior to making any claim for indemnification of those Damages under Section 9.2(a)(iv) or the Walsh Watts Matter.

(H) Seller, shall be entitled, but not obligated, to undertake and control, with the Buyer Indemnified Parties' reasonable participation, any investigation, remediation or other action required by Environmental Law (and any negotiation with Governmental Entities regarding same) with respect to such matter covered by the indemnification provisions of Section 9.2(a)(iv) or the Walsh Watts Matter, but in doing so it must avoid any material interference with the operations of the LIG Companies. The Buyer Indemnified Parties shall

cause the LIG Companies to afford the Seller reasonable access to any relevant property or facility to undertake any such investigation, remediation or other action (it being understood that if Seller does not assume responsibility for undertaking actions pursuant to this subsection, the Buyer Indemnified Parties may undertake, with the Seller's reasonable oversight and participation, in good faith, to complete such actions in a reasonably cost effective manner). Seller will indemnify Buyer and the LIG Companies from and against any Damages related to or arising from Seller's or its agents' or employees' performance of the remediation work or their presence on the premises of Buyer or the LIG Companies.

(v) Seller's indemnification obligations set forth in Section 9.2(a)(iv)(C), 9.2(a)(v), 9.2(a)(vi)(B), and 9.2(a)(viii) shall be subject to the additional limitations set forth below:

(A) Seller shall only be liable for Damages with respect to such sections to the extent that a written claim is provided to Seller in a reasonably detailed written communication prior to the second anniversary of the Closing Date and Buyer shall afford the Seller a reasonable opportunity to evaluate the conditions giving rise to such claim.

(B) No reimbursement or payment for any Damages asserted against Seller under such sections shall be required unless and until the cumulative aggregate amount of such Damages for all indemnification claims made under such sections equals or exceeds $2,000,000 (the "Special Indemnity Threshold") and then Seller shall be liable only to the extent that the cumulative aggregate amount of Damages exceeds the Special Indemnity Threshold; provided that in calculating the Special Indemnity Threshold any Damages which individually total less than Fifty Thousand United States Dollars (US $50,000) each ("De Minimis Special Indemnity Losses") shall be excluded in their entirety and Seller in any event shall have no liability hereunder to any Buyer Indemnified Parties for any such De Minimis Special Indemnity Losses regardless of the status of the Special Indemnity Threshold; provided further, that Damages totaling less than $50,000, but arising from or related to a common occurrence or related events will be aggregated and such aggregated amount shall not, if in excess of $50,000, be treated as a De Minimis Special Indemnity Loss.

(c) Notwithstanding anything to the contrary contained in this Agreement, with the exception of the Tax indemnification provisions of Article X, Sellers' aggregate liability to Buyer and its Affiliates for all Damages (including any Damages incurred to the Environmental Cap) under or relating to this Agreement and the Transition Services Agreement and the transactions contemplated hereby and thereby shall not exceed $38,100,000.

(d) The indemnities provided in this Section 9.2 shall survive the Closing. Absent an action relating to fraud, the indemnity provided in this Section 9.2 shall be the sole and exclusive remedy of the indemnified party against the indemnifying parties at law or equity for any matter covered by Section 9.2(a).

(e) Except as otherwise set forth in Section 9.2, Buyer shall give Seller prompt written notice of any third party claim which may give rise to any indemnity obligation under this Section, together with the estimated amount of such claim, and Seller shall have the right to assume the defense of any such claim through counsel of its own choosing, by so notifying Buyer within sixty (60) days of receipt of Buyer's written notice; provided, however, that Seller's counsel shall be reasonably satisfactory to Buyer. Failure to give prompt notice shall not affect the indemnification obligations hereunder in the absence of actual prejudice. If Buyer desires to participate in, but not control, any such defense assumed by Seller, it may do so at its sole cost and expense. If Seller declines to assume any such defense, it shall be liable for all reasonable costs and expenses of defending such claim incurred by Buyer, including reasonable fees and disbursements of counsel in the event it is ultimately determined that Seller is liable for such claim pursuant to the terms of this Agreement. No party shall, without the prior written consent of the other parties, which shall not be unreasonably withheld, settle, compromise or offer to

settle or compromise any such claim or demand on a basis which would result in the imposition of a consent order, injunction or decree which would restrict the future activity or conduct of the other parties or any Subsidiary or Affiliate thereof or if such settlement or compromise does not include an unconditional release of the other parties for any liability arising out of such claim or demand or any related claim or demand. The foregoing provision shall not apply to Seller's control of the matters set forth in Schedule 4.8 which shall be governed by Section 6.3(e),

(f) Notwithstanding anything to the foregoing set forth in Section 9.2(a) or anywhere else in this Agreement, Seller shall have no indemnification obligation to Buyer with respect to any Damages regarding Pipeline Integrity.

Section 9.3. Indemnification by Buyer.

(a) Except as otherwise provided in Article X below, Buyer shall defend, indemnify and hold Seller, its respective successors and permitted assigns, and its respective shareholders, members, partners (general and limited), officers, directors, managers, employees, agents, and representatives, and each of their heirs, executors, successors and assigns ("Seller Indemnified Parties") harmless from and against and in respect of any and all Damages arising out of (i) any breach of any of the representations and warranties contained in Article V hereof and made on the date hereof, (ii) any breach of any of the covenants of Buyer in this Agreement, (iii) all obligations and liabilities of whatever kind and nature, primary or secondary, direct or indirect, absolute or contingent, known or unknown, whether or not accrued, relating to the operation of the Business on or after the Closing Date and (iv) any extraordinary transactions (other than any such transactions expressly required by applicable Law or expressly provided for pursuant to this Agreement) effected by or with respect to the LIG Companies on the Closing Date that result in a Tax liability in excess of Tax liability associated with the conduct of the business in the ordinary course. Seller shall give Buyer prompt written notice of any third party claim which may give rise to any indemnity obligation under this Section, together with the estimated amount of such claim, and Buyer shall have the right to assume the defense of any such claim through counsel of its own choosing, by so notifying Seller within sixty (60) days of receipt of Seller's written notice; provided, however, that Buyer's counsel shall be reasonably satisfactory to Seller. Failure to give prompt notice shall not affect the indemnification obligations hereunder in the absence of actual prejudice. If Seller desires to participate in any such defense assumed by Buyer it may do so at its sole cost and expense. If Buyer declines to assume any such defense, it shall be liable for all costs and expenses of defending such claim incurred by Seller, including reasonable fees and disbursements of counsel. No party shall, without the prior written consent of the other parties, which shall not be unreasonably withheld, settle, compromise or offer to settle or compromise any such claim or demand on a basis which would result in the imposition of a consent order, injunction or decree which would restrict the future activity or conduct of the other parties or any Subsidiary or Affiliate thereof or if such settlement or compromise does not include an unconditional release of the other parties for any liability arising out of such claim or demand.

(b) The foregoing obligation to indemnify Seller Indemnified Parties set forth in Section 9.3(a) shall be subject to each of the following limitations:

(i) Buyer's indemnification obligation for any breach of the representations and warranties described in Article V of this Agreement shall be subject to the Survival Period limitations set forth in Section 9.1.

(ii) No reimbursement for Damages asserted against Buyer under Section 9.3(a)(i), above shall be required unless and until the cumulative aggregate amount of such Damages equals or exceeds 1.5 percent (1.5%) of the Final Purchase Price (the "Buyer Threshold") and then only to the extent that the cumulative aggregate amount of Damages, as finally determined, exceeds said Buyer Threshold; provided that in calculating such Threshold any Seller's Losses which individually total less than Fifty Thousand United States Dollars (US $50,000) each ("De Minimis Seller's

Losses") shall be excluded in their entirety and Buyer in any event shall have no liability hereunder to any Seller Indemnified Party for any such De Minimis Seller's Losses regardless of the status of the Buyer Threshold; provided further, that Damages totaling less than $50,000, but arising from or related to a common occurrence or related events will be aggregated and such aggregated amount shall not, if in excess of $50,000, be treated as De Minimis Seller's Losses.

(iii) Notwithstanding anything to the contrary contained in this Agreement, with the exception of the indemnification provisions set forth in Sections 9.3(a)(iii) and (iv), Buyer's liability to Seller Indemnified Parties for Damages in excess of the Buyer Threshold under or relating to this Agreement and the Transition Services Agreement and the transactions contemplated hereby and thereby shall not exceed $38,100,000.

(c) The indemnities provided in this Section 9.3 shall survive the Closing. Absent an action for fraud, the indemnity provided in this Section 9.3 shall be the sole and exclusive remedy of the indemnified parties against the indemnifying party at law or equity for any matter covered by Section 9.3(a).

Section 9.4. Indemnification Calculations; Mitigation.

(a) The amount of any Damages for which indemnification is provided under this Article IX shall be computed net of any insurance proceeds received by the indemnified party in connection with such Damages.

(b) The parties agree that any indemnification payments made pursuant to this Agreement shall be treated for tax purposes as an adjustment to the Final Purchase Price, unless otherwise required by applicable Law.

(c) Each indemnified party agrees that it shall pursue in good faith claims under any applicable insurance policies and against other third parties who may be responsible for any losses or Damages and each party shall have a general duty to mitigate any Damages recoverable under this Agreement.

(d) The parties agree that the indemnification provisions set forth in this Article IX shall not apply to any Damages to the extent such Damages are accounted for in the calculations of the purchase price adjustments set forth in Section 2.2.

(e) From and after the Closing, neither Buyer nor Seller nor any of their Affiliates shall agree to make any changes or modifications to any of the TRC Arrangements without the other party's prior written consent (which shall not unreasonably be withheld or delayed).

ARTICLE X
TAX MATTERS

Section 10.1. Tax Indemnification.

(a) Seller shall indemnify and hold Buyer, the LIG Companies (and their successors) and Affiliates of Buyer harmless pursuant to the procedures set forth in Section 10.3 from (x) all liability for Taxes of the LIG Companies with regard to any taxable period ending on or before the Closing Date (the "Pre-Closing Period") and the portion ending on the Closing Date of any taxable period that begins before and ends after the Closing Date (a "Straddle Period"), (y) all Taxes arising out of or related to (i) a breach of any of the representations and warranties set forth in Section 4.11 of this Agreement, assuming for purposes of this Section 10.1(a)(y) that such representations and warranties were made as of the Closing Date, or (ii) a breach of the covenant set forth in the last sentence of Section 6.14 of this Agreement, and (z) all liability (as a result of Treas. Reg. §1.1502-6(a), or any similar provision of state, local or foreign Law) for Taxes of the Seller or any other person (other than the LIG Companies) as a result of the affiliation of any of the LIG Companies with Seller or any other Person prior to Closing. Notwithstanding anything to the contrary herein, Seller shall not be obligated to indemnify Buyer against any Taxes or liabilities pursuant to this Section 10.1(a) as a result of, or

based upon or arising from, any Tax, claim or liability to the extent such Tax, claim or liability is taken into account in determining the purchase price adjustment pursuant to Section 2.2.

(b) With respect to a Straddle Period, the portion of Taxes attributable to the portion of such Straddle Period beginning before (but not ending on) the Closing Date shall be calculated as though the Straddle Period terminated as of the close of business on the Closing Date; provided, however, that in the case of a Tax not based on income, receipts, proceeds, profits or similar items, such Taxes shall be equal to the amount of Tax for the Straddle Period multiplied by a fraction, the numerator of which shall be the number of days from the beginning of the taxable period through the Closing Date and the denominator of which shall be the number of days in the Straddle Period.

(c) Buyer shall indemnify and hold the Seller harmless pursuant to the procedures set forth in Section 10.3, from and against any and all Taxes of, or pertaining or attributable to, any of the LIG Companies with respect to any taxable period or portion of a Straddle Period that begins after the Closing Date.

Section 10.2. Preparation and Filing of Tax Returns.

(a) Except as may be required by Law, no amended Tax return shall be filed, and no change in any Tax accounting method or Tax election shall be made by, on behalf of, or with respect to the LIG Companies, for any Pre-Closing Period without the consent of the Seller, which may be withheld in the Seller's sole discretion. Seller shall prepare or cause to be prepared and file or cause to be filed all Tax Returns for the LIG Companies for all Pre-Closing Periods, and shall pay all Taxes due with respect to such Tax Returns.

(b) With respect to the taxable year which includes the Closing Date, all federal income and, to the extent permissible by Law, state income Tax Returns for the LIG Companies and their Subsidiaries shall be prepared in accordance with Treas. Reg. § 1.1502-76(b)(2)(i). Seller shall not make an election described in Treas. Reg. § 1.1502-76(b)(2)(ii) to ratably allocate items to be included in such Tax Returns. Buyer and Seller agree to report all transactions not in the ordinary course of business occurring on the Closing Date after Buyer's purchase of the LIG Companies' stock on Buyer's federal income Tax Return in accordance with Treas. Reg. § 1.1502-76(b)(1)(ii)(B).

(c) With respect to any Tax Return covering a Straddle Period that is required to be filed after the Closing Date with respect to any of the LIG Companies, Buyer 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. Buyer shall prepare such Tax Return in a manner consistent with practices followed in prior years with respect to similar Tax Returns and in compliance with the Laws of each respective jurisdiction. At least forty-five (45) days prior to the due date (including any extensions) of such Tax Return, Buyer shall furnish a copy of such Tax Return to Seller. Buyer shall permit Seller to review and comment on such Tax Return and shall make such revisions to such Tax Return as reasonably requested by Seller. Buyer shall receive from Seller an amount equal to the portion of such Taxes which relates to the portion of such Straddle Period ending on the Closing Date ("Allocable Tax") no later than the due date of the Tax Return but only to the extent that such amount has not been given effect in the calculation of any purchase price adjustment pursuant to Section 2.2. Buyer shall refund to Seller any amount of Allocable Tax not properly allocable to Seller pursuant to the provisions of this Section 10.2(b), but only to the extent such amount has not been given effect in the calculation of any purchase price adjustment pursuant to Section 2.2. Buyer shall timely file such Tax Return with the appropriate Taxing Authority and pay all Taxes due with respect to such Tax Returns.

(d) In the event that a dispute arises between Seller and Buyer as to the amount of Taxes for a Straddle Period or any other issues with respect to a Tax Return covering the Straddle Period, the parties shall attempt in good faith to resolve such dispute. Upon resolution of any disputed items, the Buyer shall timely file such Tax Return and pay all Taxes due with respect to such Tax Return. If the dispute is not resolved by the time for filing of such Tax Return, the Buyer shall timely file the Tax

Return and pay the Taxes due, and the parties shall jointly request that the Neutral Auditor resolve any issue, which resolution shall be final, conclusive and binding on the parties. The scope of the Neutral Arbitrator's review shall be limited to the disputed items and the parties, shall, if necessary, file an amended Tax Return reflecting the final resolution of the disputed items. Notwithstanding anything in this Agreement to the contrary, the fees and expenses of the Neutral Auditor in resolving the dispute shall be borne one-half by Seller and one-half by Buyer. Any payment required to be made as a result of the resolution of the dispute by the Neutral Auditor shall be made within ten (10) days after such resolution, together with any interest determined by the Neutral Auditor to be appropriate. The Buyer shall not extend the statute of limitations with respect to any Tax Return of the LIG Companies for any Pre-Closing Period without the written consent of the Seller, such consent not to be unreasonably withheld.

(e) Buyer and Seller agree to provide such assistance as may reasonably be requested by such other party in connection with the preparation of any Tax Return, any audit or other examination by any Taxing Authority, or any judicial or administrative proceedings relating to liability for Taxes, and each will retain and provide the requesting party with any records or information which may be relevant to such return, audit or examination, proceedings or determination. Any information obtained pursuant to this Section 10.2(d) or pursuant to any other section hereof providing for the sharing of information relating to or review of any Tax Return or other schedule relating to Taxes shall be kept confidential by the parties hereto in accordance with Section 6.5(b).

Section 10.3. Procedures Relating to Indemnification of Tax Claims.

(a) If a claim shall be made by any Governmental Authority, for which Seller is or may be liable pursuant to this Agreement, the Buyer shall notify Seller in writing within ten (10) days of such claim (a "Tax Claim").

(b) With respect to any Tax Claim, Seller, at Seller's expense, shall control all proceedings taken in connection with such Tax Claim (including selection of counsel), and Buyer shall execute or cause to be executed powers of attorney or other documents necessary to enable Seller to take all actions desired by Seller with respect to such Tax Claim. Seller may in its sole discretion pursue or forego any and all administrative appeals, proceedings, hearings and conferences with any Taxing Authority with respect to such Tax Claim, and may initiate any claim for refund, file any amended return, or take any other action which is deemed appropriate by Seller with respect to such Tax Claim. Notwithstanding the foregoing, the Seller and Buyer shall jointly control all proceedings in connection with any Tax Claim relating solely to Taxes for a Straddle Period, and shall equally bear and pay costs and expenses related to such proceedings. No party shall settle a Tax Claim relating solely to Taxes of the LIG Companies for a Straddle Period without the other party's prior written consent (which consent may not be unreasonably withheld, conditioned or delayed; and which consent shall be considered to be unreasonably withheld if such settlement has no adverse effect on the other party).

(c) The Buyer and its Affiliates (including after the Closing, the LIG Companies), on the one hand, and the Seller, on the other hand, shall cooperate with each other in contesting any Tax Claim, which cooperation shall include, without limitation, the retention and, at the contesting party's request and expense, the provision of records and information which are reasonably relevant to such Tax Claim, and making employees available on a mutually convenient basis to provide additional information or explanation of any material provided hereunder or to testify at proceedings relating to such Tax Claim.

Section 10.4. Tax Refunds and Credits. Any refund or credits of Taxes paid or payable that are attributable to the LIG Companies for any Pre-Closing Period (or for any Straddle Period to the extent allocable (determined in a manner consistent with Section 10.2(b)) to the portion of such period beginning before and ending on the Closing Date) shall be for the account of the Seller, but only to the extent such amount has not been given effect in the calculation of any purchase price Adjustment pursuant to Section 2.2. Any refunds or credits of Taxes paid or payable that are attributable to the

LIG Companies for any other taxable period shall be for the account of the Buyer. The Buyer shall, if the Seller so requests and at the Seller's expense, shall cause the LIG Companies to file for and obtain any refunds or credits to which the Seller is entitled. The Buyer shall cause the LIG Companies to forward to the Seller any such refund within ten (10) days after the refund is received (or reimburse the Seller for any such credit within (10) days after the credit is applied against another Tax liability); provided, however, that the Seller shall indemnify the Buyer for any amount paid pursuant to this Section 10.4 if any such refund or credit is subsequently disallowed.

Section 10.5. Tax Treatment of Payments. The parties shall treat any indemnification payment made pursuant to this Agreement as a purchase price adjustment for Tax purposes.

Section 10.6. Transfer Taxes. All Transfer Taxes incurred in connection with this Agreement and the transactions that are to occur pursuant to this Agreement shall be borne by Buyer. Seller shall file, to the extent required by applicable Law, all necessary Tax Returns and other documentation with respect to such Transfer Taxes. Buyer shall pay Seller the amount shown as due on such Tax Returns, as determined in accordance with this Agreement, and shall, to the extent required by Law, join in the execution of any such Tax Return. Prior to the Closing Date, Buyer shall provide to Seller, to the extent possible, an appropriate exemption certificate in connection with this Agreement and the transactions, with respect to each applicable Taxing Authority. For purposes of this Agreement, "Transfer Taxes" shall mean transfer, documentary, sales, use, registration and other such taxes (including all applicable real estate transfer taxes).

Section 10.7. Tax Elections. Buyer and the LIG Companies (or their successors or Subsidiaries) shall not make or cause any of the LIG Companies (or their successors or Subsidiaries) to make an election pursuant to Treas. Reg. § 301.7701-3(c) or any comparable election for state, local or foreign Law purposes that will result in a change in entity classification for any of the LIG Companies or their Subsidiaries effective on or prior to the Closing Date.
