Upon the terms and subject to the conditions set forth in this Agreement, at the Closing on the Closing Date, Buyer agrees to purchase from Sellers, respectively, and Sellers hereby agree to sell, transfer and assign to Buyer, free of any and all Encumbrances other than Permitted Encumbrances, a 1% general partner interest and a 97% limited partner interest in HPL Consolidation (the “Purchased Interests”).

Purchase and Sale Agreement		Page 2

The Purchase Price will be allocated between the Sellers in the following proportion:



	Seller			Allocation
	Storage LP AEP Gas Holding II			37% 63%

2.2.2.

Closing Payment. In accordance with Section 2.4.2(a), at the Closing, Buyer will tender to Sellers or their designee the portion of the Purchase Price described in Section 2.2.1(a) hereof, plus the Initial Net Working Capital Payment pursuant to Section 2.2.3 hereof, plus the Initial Inventory Payment pursuant to Section 2.2.4 hereof (collectively, the “Closing Payment”). The amount of the Closing Payment will be reduced by $760,552 to reflect interest from the receipt of funds by the Sellers to the Valuation Time.

2.2.3.

Net Working Capital Payment. The “Net Working Capital Payment” will be equal to the net aggregate of the Initial Net Working Capital Payment and the Net Working Capital Adjustment, which in the aggregate are intended to reflect the positive or negative Net Working Capital as of the Valuation Time. The Net Working Capital Payment will be computed and paid as follows:

	(a)	At the Closing, Buyer will pay (or receive as a credit against the other elements of the Closing Payment) as part of the Net Working Capital Payment, an amount (the “Initial Net Working Capital Payment”) equal to Sellers’ good faith estimate of the aggregate Net Working Capital of the HPL Entities expected as of the Valuation Time determined in accordance with Exhibit 2.2.3. Such estimate will be based on pro forma balance sheets of the HPL Entities as of the Valuation Time, to be prepared by Sellers in accordance with GAAP and in consultation with Buyer, in the same format and level of detail as the Final Balance Sheet, and to be delivered to Buyer no later than 2 Business Days before the scheduled Closing Date.

	(b)	Within 90 days following the Closing Date, Buyer will prepare and deliver to Sellers (i) unaudited balance sheets of each of the HPL Entities as of the Valuation Time (each a “Final Balance Sheet”), prepared in accordance with GAAP consistently applied, and (ii) a detailed computation of the Net Working Capital of each of the HPL Entities as of the Valuation Time, reconciled to those balance sheets and (iii) a computation of the amount, if any, (the “Net Working Capital Adjustment”) by which the aggregate


Purchase and Sale Agreement		Page 3

Net Working Capital of the HPL Entities as of the Valuation Time, as so computed, exceeds or is less than the Initial Net Working Capital Payment. Sellers will provide Buyer and its representatives and advisors (and if appropriate, the Independent Accounting Firm), at no expense to Buyer, with all accounting services, assistance, and access to data during normal business hours to the working papers, accounting, operating, and other books and records of Sellers, and the appropriate personnel to the extent required to complete the preparation of the Final Balance Sheets and the related computations, and any deadline imposed by this Agreement on Buyer for the computation or payment of the Net Working Capital Adjustment will be extended as appropriate in light of any party’s failure to promptly make such information available. Pursuant to the Transition Services Agreement, Sellers shall also ensure that the employees of Sellers (to the extent they continue to be employed by Sellers or any Affiliate of Sellers) previously involved with the foregoing accounting services and operation activities will perform their customary and usual monthly tasks, including the assistance in the month end closing of the books and records of the HPL Entities, during the periods following the Closing Date for purposes of the foregoing. Buyer shall also ensure that the employees of Sellers (to the extent they continue to be employed by Sellers or any Affiliate of Sellers and made available under the Transition Services Agreement) and the Transferred Employees (to the extent they continue to be employed by Buyer or any Affiliate of Buyer) previously involved with the foregoing accounting services and operation activities will perform their customary and usual monthly tasks, including the assistance in the month end closing of the books and records of the HPL Entities, during the periods following the Closing Date for purposes of the foregoing. However, if Sellers have failed to assist and provide reasonable access to data as required for Buyer to complete the preparation of the Final Balance Sheets and the related computations, Buyer must notify Sellers of such failure on or before the 90^th day following the Closing Date specifying in detail the documents that Buyer requires, and Buyer will have an additional 90 days after receipt to complete the preparation of the Final Balance Sheets and the related computations. If Sellers do not dispute the Final Balance Sheets or the related computations in accordance with the next following sentence, the Net Working Capital Adjustment as computed by Buyer will be final and binding as between the parties hereto. If Sellers wish to dispute the Final Balance Sheets or the related computations, it may do so, within 30 days (or such longer period as the parties hereto may agree in writing) after the submission of the Final Balance Sheets, by notifying Buyer in writing of any disputed items in the Net Working Capital Adjustment. Sellers and Buyer shall, over


Purchase and Sale Agreement		Page 4

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 and binding for all purposes of this Agreement. If at the conclusion of the Resolution Period, Sellers and Buyer have not reached an agreement on the disputed items, then all items remaining in dispute shall be submitted by Sellers and Buyer to the Independent Accounting Firm. The Independent Accounting Firm shall act as an arbitrator to determine only those items still in dispute at the end of the Resolution Period. In making its decision, the arbitrator must render a decision on each disputed item that adopts the position of one of the parties on that item and may not decide on any other amount for that item. The parties shall instruct the Independent Accounting Firm to render its reasoned written decision as soon as practicable but in no event later than 60 days after its engagement (which engagement shall be made no later than 10 Business Days after the end of the Resolution Period). Such decision shall be set forth in a written statement delivered to Sellers and Buyer and shall be final and, binding for all purposes of this Agreement, and judgment may be entered thereon. The fees and expenses of the Independent Accounting Firm will be paid one-half by Sellers and one-half by Buyer.

	(c)	Within 30 days of receipt by Sellers of the Final Balance Sheets and related computations described in Section 2.2.3(b) hereof from Buyer (or, if Sellers dispute the same, then within 10 days of the parties’ resolution of any disputed items or receipt of the Independent Accounting Firm’s decision on any disputed items) Buyer will pay to Sellers or their designee an amount equal to any positive Net Working Capital Adjustment, or Sellers will pay to pay to Buyer an amount equal to any negative Net Working Capital Adjustment, in either such case by wire transfer and with interest thereon at the Borrowing Rate from the Closing Date to the date of payment.

	(d)	Notwithstanding any other provisions of this Agreement, no later than November 30 of the year in which the Closing occurs, Buyer will provide to Sellers a detailed schedule of property taxes for the HPL Companies for the calendar year in which the Closing occurs. Included with the schedule will be copies of each Tax statement and/or bill. The schedule will detail the allocation of property taxes to Sellers in accordance with the computation of Net Working Capital. In the event the amount of the allocation of property taxes to Sellers exceeds the amount of property taxes allocated to Sellers as computed for the Net Working Capital Adjustment computed pursuant to Section 2.2.3(b) of this Agreement, Sellers will pay the excess to Buyer within 20


Purchase and Sale Agreement		Page 5

Business Days. If the amount allocated to Sellers is less than the amount as computed for the Net Working Capital Adjustment pursuant to Section 2.2.3(b) of this Agreement, Buyer will pay to Sellers the deficit within 20 Business Days. Payments made pursuant to this Section are subject to the provisions of Section 7.5 of this Agreement. In the event of a dispute over the allocation of property taxes under this Section 2.2.3(d), Buyer and Sellers shall use the dispute resolution procedures set forth in Section 2.2.3(b) of this Agreement to resolve such dispute.

2.2.4.

Inventory Payment. The “Inventory Payment” will be equal to the net aggregate of the Initial Inventory Payment and the Final Inventory Payment Adjustment, which in the aggregate are intended to reflect the value of the Gas Inventory as of the Valuation Time. The Inventory Payment will be computed and paid as follows:

	(a)	At the Closing, Buyer will pay, as part of the Inventory Payment, the amount of $174,751,900 (the “Initial Inventory Payment”), based on Sellers’ good faith estimate of a Gas Inventory of 31,200,000 MMBtus based on the regularly maintained perpetual gas inventory records of the HPL Entities.

	(b)	Within 15 days following the Valuation Time, Buyer shall provide to Sellers a revised estimate of the Gas Inventory based on the perpetual gas inventory records in MMBtus as of the Valuation Time (the “Valuation Time Estimate”). The “Valuation Time Adjustment Amount” shall be the number of MMBtus determined by subtracting 31,200,000 MMBtus from the Valuation Time Estimate. In the event the Valuation Time Adjustment Amount is a positive number, Buyer shall pay to Sellers, or Sellers’ designee, within 15 days of receipt of an invoice, an amount equal to the Valuation Time Adjustment Amount multiplied by $5.601. In the event the Valuation Time Adjustment Amount is a negative number, Sellers shall pay to Buyer, or Buyer’s Designee, within 15 days of receipt of an invoice, an amount equal to the Valuation Time Adjustment Amount multiplied by $5.601 plus $0.40 per MMBtu. Any payment under this Section 2.2.4(b) shall be made by wire transfer and is the “Valuation Time Adjustment”.

	(c)	No later than 90 days following the Closing Date, Buyer may deliver written notice (the “Inventory Verification Notice”) to Sellers advising them whether or not it has elected to undertake a verification of the actual storage inventory contained in the Bammel Facilities. Any election by Buyer to undertake (or not undertake) such verification shall be final and irrevocable in all respects. In the event Buyer timely delivers an Inventory Verification Notice advising Sellers that it has elected to


Purchase and Sale Agreement		Page 6

undertake such a verification, Buyer and Sellers shall engage Wells Chappell & Company, Inc. (“Wells”) to perform such verification in accordance with the procedures and methods set forth on Exhibit 2.2.4 (with all fees and expenses of Wells to be borne 1/2 by Buyer and 1/2 by Sellers). Buyer and Sellers shall instruct Wells to complete its physical verification testing of the actual storage volume of the Bammel Facilities no later than 120 days after the Closing Date (and shall each use their reasonable best efforts to ensure that such testing is completed by Wells no later than 120 days after the Closing Date), and to deliver to each of them no later than 30 days after its completion a copy of its verification of the actual storage volume of the Bammel Facilities and any supporting documentation therefor, and any deadline imposed by this Agreement on Buyer or Sellers which is contingent upon Wells’ verification of the actual storage volume of the Bammel Facilities will be extended as appropriate in light of any failure by Wells to promptly complete and deliver its verification of the actual storage volume of the Bammel Facilities and any supporting documentation therefor. Based upon the results of this verification, Buyer shall (i) recompute in accordance with Exhibit 2.2.4 that portion of the amount of the Gas Inventory as of the Valuation Time that was stored in the Bammel Facilities (as so recomputed, the “Recomputed Bammel Inventory”) and (ii) deliver to Sellers a statement thereof (“Buyer’s Statement of Recomputed Bammel Inventory”) no later than 180 days following the Closing Date. However, if Wells has failed to promptly complete and deliver its verification of the actual storage volume of the Bammel Facilities and any supporting documentation therefor, Buyer must notify Sellers of such failure on or before the 150^th day following the Closing Date, and Buyer will have an additional 30 days after receipt of the verification of the actual storage volume of the Bammel Facilities and any supporting documentation therefor from Wells to complete the Recomputed Bammel Inventory and Buyer’s Statement of Recomputed Bammel Inventory. In the event (A) Buyer does not timely deliver to Sellers the Inventory Verification Notice, (B) Buyer does not deliver to Sellers Buyer’s Statement of Recomputed Bammel Inventory on or prior to 180 days following the Closing Date (or if Wells has failed to promptly complete and deliver its verification of the actual storage volume of the Bammel Facilities and any supporting documentation therefor, on or prior to 30 days after receipt of such verification), (C) Buyer timely delivers an Inventory Verification Notice stating that it shall not cause a verification of the actual storage volume of the Bammel Facilities to be undertaken, or (D) the amount of Recomputed Bammel Inventory set forth on Buyer’s Statement of Recomputed Bammel Inventory is not more than 1.03, and not less than 0.97, times that portion of


Purchase and Sale Agreement		Page 7

the Gas Inventory as of the Valuation Time that was stored in the Bammel Facilities according to the most current perpetual gas inventory records (the events referred to in the immediately preceding clauses (A) through (D) inclusive each being referred to as a “Inventory Finalization Event”), Buyer shall have no right to thereafter conduct a verification of the actual storage inventory contained in the Bammel Facilities for purposes of any adjustment pursuant to this Agreement. If Buyer provides to Sellers a timely Buyer’s Statement of Recomputed Bammel Inventory which indicates that the Recomputed Bammel Inventory is more than 1.03, or less than 0.97, times that portion of the Gas Inventory as of the Valuation Time that was stored in the Bammel Facilities according to the most current perpetual gas inventory records (such event being referred to herein as a “Bammel Inventory Recomputation Event”), then subject to the provisions of Section 2.2.4(d) hereof the Recomputed Bammel Inventory will be used for all purposes of Section 2.2.4(e) hereof as the final actual storage inventory of the Bammel Facilities as of the Valuation Time.

(d)

The provisions of this Section 2.2.4(d) shall apply only if a Bammel Inventory Recomputation Event occurs. After receipt of Buyer’s Statement of Recomputed Bammel Inventory, Sellers shall have 30 days to review and dispute Buyer’s Statement of Recomputed Bammel Inventory (which dispute may not include any challenge to or disagreement with the results reported by Wells of its verification of the actual storage volume of the Bammel Facilities), and for this purpose will have the right to review, copy, abstract, and audit all relevant meter data and other relevant information held by or available to the HPL Entities for the period from the Valuation Time through the date as of which the Recomputed Bammel Inventory was determined by Wells. Buyer will provide Sellers and their representatives and advisors, at no expense to Sellers, with all accounting services, assistance, and access to data during normal business hours to the working papers, accounting, operating, and other books and records of the HPL Entities, and the appropriate personnel to the extent required to review and audit the Recomputed Bammel Inventory, and any deadline imposed by this Agreement on Sellers for the completion of that review and audit will be extended as appropriate in light of Buyer’s or its Affiliates’ failure to promptly make such information available. Pursuant to the Transition Services Agreement, Buyer shall also ensure that the employees of Sellers (to the extent they continue to be employed by Sellers or any Affiliate of Sellers and made available under the Transition Services Agreement) previously involved with the foregoing accounting services and operation activities will perform their customary and usual monthly tasks, including the


Purchase and Sale Agreement		Page 8

assistance in the month end closing of the books and records of the HPL Entities, during the periods following the Closing Date for purposes of the foregoing. Buyer shall also ensure that the Transferred Employees (to the extent they continue to be employed by Buyer or any Affiliate of Buyer) previously involved with the foregoing accounting and operation activities will perform their customary and usual monthly tasks, including the assistance in the month end closing of the books and records of the HPL Entities, during the periods following the Closing Date for purposes of the foregoing. However, if Buyer has failed to assist and provide reasonable access to data as required for Sellers to complete their review, Sellers must notify Buyer of such failure on or before the 30^th day after receipt of Buyer’s Statement of Recomputed Bammel Inventory specifying in detail the documents that Sellers require, and Sellers will have an additional 90 days after receipt to review Buyer’s Statement of Recomputed Bammel Inventory and notify Buyer of a dispute. On or prior to the 30^th day after receipt of Buyer’s Statement of Recomputed Bammel Inventory and supporting documentation (including access to and audit of such data and information), Sellers shall deliver written notice to Buyer, specifying in detail any disputed items and the basis therefor. If Sellers fail to so notify Buyer of any such disputes or failures on or prior to the 30^th day after receipt of Buyer’s Statement of Recomputed Bammel Inventory, the calculations set forth on Buyer’s Statement of Recomputed Bammel Inventory will be used for all purposes of Section 2.2.4(e) hereof as the final actual storage inventory of the Bammel Facilities as of the Valuation Time. If Sellers so notify Buyer of any disputed items on Buyer’s Statement of Recomputed Bammel Inventory, Buyer and Sellers 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 and binding for all purposes of Section 2.2.4(e) hereof as the final actual storage inventory of the Bammel Facilities as of the Valuation Time. If at the conclusion of the Resolution Period, Sellers, 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 Sellers and Buyer to the Independent Accounting Firm. The Independent Accounting Firm shall act as an arbitrator to determine only those items still in dispute at the end of the Resolution Period. In making its decision, the arbitrator must render a decision on each disputed item that adopts the position of one of the parties on that item and may not decide on any other amount for that item. The parties shall instruct the Independent Accounting Firm to render its reasoned written decision as soon as practicable but in no event later than 60 days after its engagement (which engagement shall


Purchase and Sale Agreement		Page 9

be made no later than 10 Business Days after the end of the Resolution Period). Such decision shall be set forth in a written statement delivered to Sellers and Buyer and shall be final and binding on the parties hereto for all purposes of Section 2.2.4(e) hereof as the final actual storage inventory of the Bammel Facilities as of the Valuation Time. The fees and expenses of the Independent Accounting Firm will be paid one-half by Sellers and one-half by Buyer.

(e)

Within 90 days following the Closing Date (or, if there has been a Bammel Inventory Recomputation Event, then within 30 days following the determination under Sections 2.2.4(c) and/or 2.2.4(d) of the final actual storage inventory of the Bammel Facilities as of the Valuation Time), Buyer will prepare and deliver to Sellers (i) a computation of the Gas Inventory as of the Valuation Time, taking into account any final actual storage inventory of the Bammel Facilities as of the Valuation Time determined under Sections 2.2.4(c) and/or 2.2.4(d) (it being understood that, except in the event of a failure by Wells to promptly complete and deliver its verification of the actual storage volume of the Bammel Facilities and any supporting documentation therefor, unless the procedures and time limits for the determination of the actual storage inventory under Sections 2.2.4(c) and/or 2.2.4(d) are fully complied with, no results of any physical storage inventory will be used for purposes of this Section 2.2.4(e), and (ii) a computation of the Final Inventory Payment Adjustment. Sellers will provide Buyer and its representatives and advisors (and if appropriate, the Independent Accounting Firm), at no expense to Buyer, with all accounting services, assistance, and access to data during normal business hours to the working papers, accounting, operating, and other books and records of Sellers, and the appropriate personnel to the extent required to complete the computation of the Gas Inventory and the Final Inventory Payment Adjustment, and any deadline imposed by this Agreement on Buyer for the computation or payment of the Final Inventory Payment Adjustment will be extended as appropriate in light of Sellers’ or their Affiliates’ failure to promptly make such information available. Pursuant to the Transition Services Agreement, Buyer shall also ensure that the employees of Sellers (to the extent they continue to be employed by Sellers or any Affiliate of Sellers and made available under the Transition Services Agreement) previously involved with the foregoing accounting services and operation activities will perform their customary and usual monthly tasks, including the assistance in the month end closing of the books and records of the HPL Entities, during the periods following the Closing Date for purposes of the foregoing. Buyer shall also ensure that the Transferred Employees (to the extent they


Purchase and Sale Agreement		Page 10

continue to be employed by Buyer or any Affiliate of Buyer) previously involved with the foregoing accounting services and operation activities will perform their customary and usual monthly tasks, including the assistance in the month end closing of the books and records of the HPL Entities, during the periods following the Closing Date for purposes of the foregoing. However, if Sellers have failed to assist and provide reasonable access to data as required for Buyer to complete the computation or payment of the Final Inventory Payment Adjustment, Buyer must notify Sellers of such failure on or before the 90^th day following the Closing Date or, if there has been a Bammel Inventory Recomputation Event, then within 30 days following the determination under Sections 2.2.4(c) and/or 2.2.4(d) of the final actual storage inventory of the Bammel Facilities as of the Valuation Time) specifying in detail the documents that Buyer requires, and Buyer will have an additional 90 days after receipt to complete the preparation and delivery of such computations. If Sellers do not dispute the computation of the Gas Inventory or the related computation of the Final Inventory Payment Adjustment in accordance with the next following sentence, the Final Inventory Payment Adjustment as computed by Buyer will be final and binding as between the parties hereto. If Sellers wish to dispute the computation of the Gas Inventory or the related computation of the Final Inventory Payment Adjustment, they may do so, within 30 days (or such longer period as the parties hereto may agree in writing) after the submission of the Final Inventory Payment Adjustment, by notifying Buyer of any disputed items in the Gas Inventory or the related computation of the Final Inventory Payment Adjustment. No such dispute may include a reconsideration of any final actual storage inventory of the Bammel Facilities as of the Valuation Time determined under Sections 2.2.4(c) and/or 2.2.4(d). Sellers and Buyer 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 and binding for all purposes of this Agreement. If at the conclusion of the Resolution Period, Sellers and Buyer have not reached an agreement on the disputed items, then all items remaining in dispute shall be submitted by Sellers and Buyer to the Independent Accounting Firm. The Independent Accounting Firm shall act as an arbitrator to determine only those items still in dispute at the end of the Resolution Period. In making its decision, the arbitrator must render a decision on each disputed item that adopts the position of one of the parties on that item and may not decide on any other amount for that item.

5.1.	Continuing Access.

	After the Closing Date and in addition to any rights under the Cushion Gas Litigation Agreement, each of the parties hereto, its Affiliates, and its and their representatives and advisors will have reasonable access to (and the right to make and retain copies of) the records (including, but not limited to email messages) of the HPL Companies and reasonable access to the officers, directors, then-serving employees, members, agents, and any other personnel of the HPL Companies, in each case for purposes of consultation or otherwise to the extent reasonably required in connection with matters relating to the operations of the HPL Companies before the Closing Date, in connection with the performance of its obligations and exercise of its rights under this Agreement (including its prosecution, defense, and settlement of Retained Matters or other litigation or investigations), or otherwise in connection with the Contemplated Transactions. Each of the parties hereto agrees to preserve and cause its Affiliates to preserve all such records for the period of time set forth in any records retention policy in effect at an HPL Entity as of the Closing Date or for any longer period as may be required by law, but in any event for at least 6 years from the Closing Date. Each of the parties hereto and their representatives and advisors will have reasonable access to (and the right to make and retain copies of) the documents, books and records, and other information of the HPL Companies (to the extent currently possessed by the HPL Companies, and such parties shall authorize Buyer or Sellers, as applicable, to seek or obtain, at the expense of the party seeking such access, such documents, books, records, and other information of the HPL Companies that are not currently possessed by such parties). At no cost or expense to the cooperating party other than actual out-of-pocket expenditures (which shall not include attorney’s fees), each party will reasonably (or otherwise upon reimbursement of the cooperating party’s out-of- pocket costs) cooperate and cause their Affiliates to reasonably (or otherwise upon reimbursement of the cooperating party’s out-of-pocket costs) cooperate in connection with any audit, investigation, hearing, or inquiry by any Governmental Authority and any litigation, arbitration, or other Proceeding which may continue or arise after the Closing Date relating to any of the Retained Matters, such cooperation to include making individuals and records reasonably (or otherwise upon reimbursement of Buyer’s out-of-pocket costs) available for review, analysis, testing, consultation, interview, deposition, or testimony, making a corporate representative available for deposition or at trial, and executing declarations, affidavits, settlement agreements, and other instruments as reasonably requested by the other party hereto. Any cost associated with accessing former employees will be borne by the party seeking such access.

Purchase and Sale Agreement		Page 30

		otherwise direct the prosecution, defense, and settlement of any of the Proceedings described as or arising out of “Retained Matters” in Sellers’ Disclosure Schedules and Buyer covenants to cause the HPL Entities to grant such control to Sellers. Following the Closing, the liability of the HPL Entities for any demands, claims, causes of action, suits, judgments, damages, amounts paid in settlement, penalties, liabilities, losses or deficiencies, court costs, expenses of arbitration or mediation, and other out-of-pocket expenses relating to any Retained Matter (“Retained Matter Liabilities”) will be limited as set out in the description thereof in Sellers’ Disclosure Schedule, and Sellers hereby agree to solely bear the cost of, or if unable to directly bear the cost of, shall indemnify and hold harmless, the HPL Entities from all Retained Matter Liabilities in excess of such limit on the liability of the HPL Entities therefor (“Sellers’ Retained Matter Responsibility”), in accordance with the provisions of Section 6.2. Sellers will retain rights in proportion to Sellers’ Retained Matter Responsibility with respect to any recovery from any of the Retained Matters or any counterclaim thereto or cross-claim with respect thereto (whether or not presently asserted), and Buyer agrees to immediately remit, and cause the HPL Entities to immediately remit, any and all such recoveries to Sellers or their designees.

	5.2.2.	Cushion Gas Litigation is not a Retained Matter under this Agreement.

5.3.	Workforce Matters.

5.3.1.

Post-Closing Employment and Compensation; Severance.

(a)

Sellers have transferred, or have caused to be transferred, all members of the Closing Workforce to a Seller or an Affiliate of a Seller (other than an HPL Company). From the Closing Date until the expiration of the Employee Review Period, Sellers shall be responsible for the Closing Workforce in accordance with the terms of the Transition Services Agreement. Not later than 100 days following the Closing Date (such period being the “Employee Review Period”), except as provided in Section 5.3.1(b), Buyer shall extend offers of employment, or cause the HPL Entities or another of its Affiliates to extend offers of


Purchase and Sale Agreement		Page 31

employment, to the members of the Closing Workforce that it so elects with terms consistent with Section 5.3.2 (“Offer of Employment”). Buyer will make Offers of Employment and initiate employment in consultation with Sellers in an orderly fashion that does not impose an undue administrative burden on Sellers. Buyer shall notify Sellers in writing at least 10 days prior to making an Offer of Employment of: (i) the name of each such member of the Closing Workforce to whom Buyer or an Affiliate of Buyer intends to make an Offer of Employment; and (ii) the terms of each such Offer of Employment. Buyer shall not give notice to any member of the Closing Workforce that such employee will not receive an Offer of Employment in the period beginning on the Closing Date and ending 30 days after the Closing Date. At any time and from time to time on or before the date that is the last day of the Employee Review Period, Buyer or an Affiliate of Buyer shall hire those members of the Closing Workforce who accept an Offer of Employment. Each member of the Closing Workforce who accepts an Offer of Employment shall be referred to as a “Transferred Employee”. The date on which a Transferred Employee becomes an employee of Buyer or Buyer’s Affiliate shall be referred to as the “Hire Date” for such Transferred Employee. Sellers or their Affiliate, as the case may be, shall terminate each of the Transferred Employees as of such employee’s Hire Date. Except to the extent that such liabilities are to be borne by Buyer under Section 5.3.1(c), Sellers shall be liable for any Required Severance Benefits and health care continuation benefits (COBRA rights) of any member of the Closing Workforce that does not become a Transferred Employee, and except as otherwise provided herein or in the Transition Services Agreement, neither Buyer nor any Affiliate thereof shall have any other liability or obligation whatsoever with respect to any member of the Closing Workforce who does not become a Transferred Employee.

(b)

The provisions of Section 5.3.1(a) notwithstanding, (i) Buyer will have no obligation to employ, or cause to be employed, any member of the Closing Workforce who does not accept an Offer of Employment that conforms to the requirements of Section 5.3.1(a); (ii) Buyer will have no obligation to continue the employment of any individual who voluntarily terminates his or her employment other than in the circumstances described in clause (ii) or (iii) of Section 5.3.1(c), and (iii) Buyer may terminate the employment of any member of the Closing Workforce at anytime for Cause. For purposes of this Agreement, termination for “Cause” means termination because of material dereliction of duty, commission of a crime of moral turpitude, material violation of any written policy of the employer, or termination because of any other “termination for


Purchase and Sale Agreement		Page 32

		cause” provision in the involved individual’s written employment agreement, if any.

	(c)	Buyer will provide, or will cause the HPL Entities or another of its Affiliates to provide the Required Severance Benefits to each Transferred Employee who:

	(i)	is terminated without Cause during the Continuation Period,

	(ii)	elects during the Continuation Period to terminate such employment within 7 days following such Transferred Employee’s receipt of a notice from his or her employer of its intent to reduce such employee’s base rate of pay, or

	(iii)	elects during the Continuation Period to terminate such employment within 30 days after his or her employer notifies such employee of its intent to assign such employee to a principal place of work that is more than 50 miles from such employee’s principal place of work as of the Closing Date.

Additionally, in the event Buyer fails to extend, or cause to be extended, Offers of Employment to not less than 75% of the Closing Workforce as required by Section 5.3.1(a), and the members of the Closing Workforce that are severed by Sellers or their Affiliates who have not received Offers of Employment from Buyer and have not resigned or have not received offers of employment from Sellers or any of their Affiliates that in each such case would relieve Sellers of any severance obligation to such employees, then Buyer will pay to Sellers or their designated Affiliate, within 30 days of written request therefor (such request to be made within 30 days of the end of the Employee Review Period) an amount equal to (A) the weighted average severance benefits (based on credited service and COBRA premium rates determined as of the last day of the Employee Review Period) that could be available pursuant to the Required Severance Benefits to the remaining members of the Closing Workforce described above multiplied by (B) a number equal to (x) the number of individuals constituting 75% of the Closing Workforce minus (y) the number of individuals who receive an Offer of Employment that conforms to the requirements of Section 5.3.1(a).

(d)

Sellers and their Affiliates will not discourage any member of the Closing Workforce from accepting an Offer of Employment that conforms to the requirements of Section 5.3.1(a).


Purchase and Sale Agreement		Page 33

(e)

Prior to the Closing Date, Sellers shall have caused the HPL Entities to (i) terminate any Benefit Plans that are sponsored, contributed to, maintained, or entered into solely by one or more of the HPL Entities, unless sponsorship is transferred to and assumed by a Seller or an Affiliate of Sellers (other than an HPL Company) prior to the Closing Date (including any liability that might otherwise apply to the HPL Entities), and (ii) terminate the participation of all HPL Entities in all Benefit Plans. It is expressly understood and agreed that neither Buyer nor any Affiliate thereof is, by virtue of this Agreement or otherwise, assuming any Benefit Plan or any liability or obligation of any kind under any such Benefit Plan.

5.3.2.

Post-Closing Benefits; Service Credit for Transferred Employees.

	(a)	During the Continuation Period, Buyer will provide, or cause the HPL Entities or another of its Affiliates to provide, Transferred Employees with (i) a base compensation level at least as high as that referred to in Section 3.17.1 hereof (including scheduled increases in compensation identified therein), and (ii) a principal place of work that is no more than 50 miles from such Transferred Employee’s principal place of work as of the day immediately preceding Closing.

	(b)	During the Continuation Period, Buyer will provide, or cause the HPL Entities or another of its Affiliates to provide, to the extent permitted by Applicable Law, bonus, fringe benefits, welfare benefits, retirement and pension benefits, medical, dental, and other health plans, vacation pay, sick leave, deferred compensation arrangements, and other benefits (other than severance benefits, which are controlled by Section 5.3.1(c)) (the “Buyer Plans”) for Transferred Employees that are no less favorable than those provided by Buyer or its Affiliates to other similarly situated employees of Buyer or its Affiliates.

	(c)	To the extent permitted under Applicable Law and the applicable Buyer Plans, Buyer agrees that for purposes of all Buyer Plans (including all policies and employee fringe benefit programs, including vacations, of Buyer) under which an employee’s benefit depends, in whole or in part, on length of service, credit will be given to Transferred Employees as of each employee’s Hire Date for service previously credited with or by Sellers or any of their Affiliates prior to such Hire Date for such programs, provided that such crediting of service shall not be given for benefit accrual purposes under any defined benefit plan. If permitted under the applicable Buyer Plans with no immediate increase in Buyer’s premiums with respect to any insured group health plan, each Transferred Employee shall also be given credit


Purchase and Sale Agreement		Page 34

		for any deductible or co-payment amounts paid in respect of the plan year in which the Closing occurs to the extent that, following such employee’s Hire Date, such Transferred Employee participates in any Buyer Plan for which deductibles or co-payments are required. Buyer shall also cause each Buyer Plan (except Buyer’s insured welfare benefit plans that are not group health plans, with respect to which Buyer shall use its commercially reasonable efforts to cause such plans) to waive (i) any preexisting conditions, exclusions, evidence of insurability requirements, and actively-at-work exclusions for each Transferred Employee and his or her dependents under any Buyer Plan in which a Transferred Employee becomes eligible to participate to the extent that such pre-existing conditions, exclusions, evidence of insurability requirements, and actively-at-work exclusions were previously satisfied under the comparable Benefit Plan, and (ii) any waiting period limitation which would otherwise be applicable to a Transferred Employee on or after the Closing to the extent such Transferred Employee had satisfied any similar waiting period limitation under an analogous plan prior to the Closing. All claims and expenses incurred by any such Transferred Employee and any dependents that were to be taken into account for purposes of satisfying any deductible or out-of-pocket limit under any Benefit Plan will be taken into account for purposes of satisfying any deductible or out-of-pocket limit under the plans maintained after Closing for the benefit of such Transferred Employee. Sellers shall use their reasonable best efforts to provide to Buyer information concerning out-of-pocket expenses incurred by Transferred Employees under any Benefit Plan for pre-Hire Date treatments or services.

	(d)	Buyer will recognize, or will cause the HPL Entities or another of its Affiliates to recognize, all unused earned, banked, and accrued vacation of each Transferred Employee as of such employee’s Hire Date up to a maximum of 2 weeks of vacation for each Transferred Employee and will provide to each such Transferred Employee a level of sick leave and other leave benefits that is no less favorable than the sick leave and other leave benefits provided by Buyer or its Affiliates to similarly situated employees of Buyer or its Affiliates. If any Transferred Employee has more than 2 weeks unused earned, banked, and accrued vacation available to be taken in the year of Closing under Sellers’ or their Affiliates’ vacation policy as of such Transferred Employee’s Hire Date, Sellers shall be responsible for the payment to such Transferred Employee of such additional amount of unused earned, banked, and accrued vacation based on such Transferred Employee’s salary immediately prior to the Hire Date. At any time and from time to time during the Employee


Purchase and Sale Agreement		Page 35

Review Period, at Buyer’s request, Sellers will prepare a report of the amounts accrued by Sellers and their Affiliates for vacation benefits of the Closing Workforce. To the extent that Buyer provides such benefits to the Transferred Employees as a result of such accruals (rather than as a result of accruals from service after the Transferred Employee’s Hire Date), Sellers will remit to Buyer the amount of such accruals as a reduction of the Purchase Price.

(e)

Buyer will provide or cause to be provided to each Transferred Employee and their qualified beneficiaries who incur a “qualifying event” (as defined in COBRA) on or after such Transferred Employee’s Hire Date continuation health coverage in accordance with the continuation health coverage requirements of COBRA.

	5.3.3.	WARN Act Compliance.

		Sellers do not anticipate terminating the employment of any member of the Closing Workforce prior to Closing as a result of the Contemplated Transactions. Buyer will, at its expense, effect or cause the HPL Entities or its other Affiliates to effect full compliance with the Worker Adjustment and Retraining Notification Act (“WARN Act”) and regulations promulgated thereunder, and any comparable state or local Applicable Law, required as a result of the Contemplated Transactions, regardless of whether the obligation to do so is that of Buyer, Sellers, their Affiliates, or the HPL Entities. Buyer agrees to indemnify Sellers for any damages, costs, fees, including but not limited to attorneys’ fees, penalties, or other legal obligations under the WARN Act or comparable state or local Applicable Law, resulting from the Contemplated Transactions.

5.4.	Discontinuation of Intercompany Transactions.

	Effective as of the Closing, and consistent with the determination of Net Working Capital, all intercompany receivables and payables and loans including amounts due to or from the HPL Entities under the AEP System Amended and Restated Non-Utility Money Pool Agreement then existing between any HPL Entity on the one hand and AEP or any of its Affiliates on the other hand (other than those between the HPL Entities) shall be fully settled so that there are, as of the Valuation Time, no such outstanding payables, receivables, or loans except as set forth in Sellers’ Disclosure Schedules. Without limitation of the foregoing, all accruals of federal income tax and state income tax, all deferred tax liabilities, and all deferred tax assets will be eliminated from the accounts of the HPL Entities. Except as set forth in Sellers’ Disclosure Schedules, all intercompany agreements or arrangements between any HPL Entity on the one hand and AEP or any of its Affiliates on the other hand including agreements for accounting services and access to accounting processes (other than those between the HPL Entities) shall be terminated as of the Valuation Time.


Purchase and Sale Agreement		Page 36

5.5.	Termination and Continuation of Certain Insurance Coverages.

	5.5.1.	Buyer acknowledges that as of Closing the insurance coverages relating to the Business and described as “Terminating Insurance Coverages” in Sellers’ Disclosure Schedules will terminate or otherwise cease to be in effect, except with respect to claims of any of the HPL Companies that are pending under such insurance coverage as of the Closing Date, which shall survive the Closing Date and continue in effect until resolution thereof. No HPL Company will be entitled to any refund of any premium paid with respect to any such coverage. Except as otherwise provided in this Agreement, Buyer agrees that it will be solely responsible for, and neither Sellers nor any of their Affiliates will have any responsibility for, all risks as to which a claim for coverage under any of the Terminating Insurance Coverages may have otherwise been brought after Closing.

	5.5.2.	Until December 20, 2006, and thereafter at the option and expense of Sellers, Buyer will maintain, or cause the HPL Entities to maintain, continuously in force Chubb Custom Insurance Company Policy Number 3725-37-46 (or an equivalent policy from an insurer acceptable to Sellers in their sole discretion) covering insured losses, providing for deductibles and limits, and including endorsements, in each case, as presently set forth in such policy, and naming AEP and its Affiliates as additional named insureds. Buyer shall notify Sellers at least 60 days prior to the end of the coverage period of its intention to not renew the above-described policy. If such coverage is extended at the option and expense of Sellers, Sellers shall have the sole right to modify and limit coverage at their discretion.

5.6.	Substitutions of Credit Support.

	Buyer shall, within 30 days following the Closing Date, cause itself or one or more of its Affiliates to be substituted in all respects for Sellers or one or more of their Affiliates, as the case may be, in respect of all obligations of Sellers or any of their Affiliates under each and every guaranty, indemnity agreement, surety bond, performance bond, letter of credit, support agreement, keep-well agreement, third party collateral assignment or other pledge of collateral, or other credit support arrangement of any kind supporting the credit or facilitating the transactions of any of the HPL Companies in connection with the Business (each a “Credit Support Arrangement”) and shall cause Sellers and each of their Affiliates, as the case may be, to be discharged from all obligations under any such Credit Support Arrangement. The Credit Support Arrangements include those listed in Schedule 5.6 of Sellers’ Disclosure Schedules. If Buyer is unable to timely effect such substitution with respect to any Credit Support Arrangement on terms acceptable to Buyer, then Buyer will immediately obtain a letter of credit, on terms and from a financial institution reasonably satisfactory to Sellers, with respect to the obligations of Sellers and each of their Affiliates under such Credit Support Arrangement.


Purchase and Sale Agreement		Page 37

5.7.	Claims for Certain Measurement Adjustments.

	Buyer agrees to remit to Sellers, within 30 days of receipt, any amount receivable within the 18 months following the Closing Date to correct any misallocation, calculation error, measurement problem or similar event relating to performance prior to the Closing Date under any of the HPL Companies’ contracts with gas suppliers, gas customers, transportation customers, and storage customers. If any such amount is offset for any reason, the amount so offset will be remitted within 30 days of the date on which the HPL Companies receive credit as a result of such offset. Sellers will have the right to direct Buyer and the HPL Companies in the administration of any contract provision calling for any such a correction to the extent necessary to protect its interests under this Section 5.7. At the expense of Sellers, Sellers shall have the right, in accordance with this Section 5.7 and Section 5.1, to audit the records of the HPL Entities to determine the existence of a right to any such correction and/or the details concerning any such correction and for this purpose will have the right, in accordance with this Section 5.7 and Section 5.1, to review, copy, abstract, and audit all relevant meter data and other relevant information held by or available to the HPL Entities for the relevant period. Buyer will provide Sellers and their representatives and advisors, at no expense to Sellers, with all accounting services, assistance, and access to data during normal business hours to the working papers, accounting, operating, and other books and records of the HPL Entities, and the appropriate personnel to the extent required to exercise Sellers’ rights under this Section 5.7. Pursuant to the Transition Services Agreement, Buyer shall also ensure that the employees of Sellers (to the extent they continue to be employed by Sellers or any Affiliate of Sellers and made available under the Transition Services Agreement) previously involved with the foregoing accounting services and operation activities will perform their customary and usual monthly tasks, including the assistance in the month end closing of the books and records of the HPL Entities, during the periods following the Closing Date for purposes of the foregoing. Buyer shall also ensure that the Transferred Employees (to the extent they continue to be employed by Buyer or any Affiliate of Buyer) previously involved with the foregoing accounting services and operation activities will perform their customary and usual monthly tasks, including the assistance in the month end closing of the books and records of the HPL Entities, during the periods following the Closing Date for purposes of the foregoing.

5.8.	Discontinuance of Trademarks and Tradenames.

	Any and all Intellectual Property owned by or licensed to the HPL Companies with respect to the name “Houston Pipe Line Company” or the acronym “HPL” or any variation or derivative thereof (the “Business Marks”) shall be retained by the HPL Companies for their use after Closing. Effective upon Closing Sellers shall cause their appropriate Affiliates to grant to the HPL Companies a non-exclusive, non-transferable, non-sublicenseable, royalty-free right to display, solely in connection with the Business, “AEP”, “American Electric Power” or any other similar trademarks, service marks, and tradenames owned by or licensed to Sellers or any of their Affiliates (the “Retained Marks”), for a period of time, not to exceed 6 months from the Closing Date, as is reasonably necessary to promptly discontinue such


Purchase and Sale Agreement		Page 38

	display, on any stationery, billing stock, signs, vehicles, pipeline markers, manuals, forms, or in connection with the normal operation of computer software, but solely to the extent and in the form that the Retained Marks exist or are contained thereon as of the Closing. At the conclusion of such period, Buyer shall cause each of the HPL Companies to discontinue display or other use of, and license to others of, the Retained Marks.

5.9.	Change of Sellers’ Names.

	At Closing each Seller will take all steps necessary to change its name effective as of the Closing Date so as to eliminate any reference to “HPL”.

5.10.	Required Notices.

	Buyer will timely prepare and file or cause to be prepared and filed, at its own expense, with a complete and contemporaneous copy to Sellers, all notices or other filings required to be filed by any HPL Company or Buyer after Closing with any Governmental Authority as a result of or with respect to the execution and delivery of this Agreement or the Buyer’s Documents or the consummation of the Contemplated Transactions. Upon the request of Buyer, Sellers will fully cooperate with Buyer in making any such filing.

5.11.	Public Statements.

	After the Closing Date, no party will issue any press release or make any public disclosure concerning the Contemplated Transactions or the contents of this Agreement, the Option Agreement, the Cushion Gas Litigation Agreement, the Guaranties, or the Transition Services Agreement without the prior written consent of the other parties, which shall not be unreasonably withheld. Notwithstanding the above, nothing in this Section will preclude any party from making any disclosures required by Applicable Law or necessary and proper in conjunction with the filing of any tax return or other document required to be filed with any Governmental Authority or to comply with the regulations of any securities exchange; provided, that the party required to make such disclosure shall allow the other parties reasonable time to review and comment thereon in advance of such disclosure.

5.12.	Audit Matters.

	Promptly following Closing, Sellers will provide representatives of Buyer, at no expense to Sellers, with all assistance and access to data during normal business hours, including accounting and other books and records of the HPL Entities and Sellers and the appropriate personnel of Sellers and the HPL Entities, reasonably required by Buyer to enable Buyer to prepare for the HPL Entities: (i) an audited balance sheet as may be required or, in the judgment of Buyer, advisable to be filed by Buyer or any Affiliate of Buyer in accordance with Regulation S-X under the Securities Act of 1933, as amended, and related statements of income and cash flows for each of its then three most recent fiscal years, or (ii) other financial statements (including without limitation adjusted historical financial statements), in each case as may be required or


Purchase and Sale Agreement		Page 39

	advisable for filings with the Securities and Exchange Commission in compliance with Regulation S-X in connection with or on account of the Contemplated Transactions. Buyer, at its sole expense, shall engage independent auditors to undertake the above-described audit, and if Buyer engages Deloitte & Touche, LLP, Sellers (at no expense to Sellers) will authorize access to that firm’s working papers relating to its audit of AEP insofar as they relate exclusively to Sellers and their direct and indirect subsidiaries. It is expressly agreed that no Buyer representative, including the independent auditors engaged by Buyer as contemplated by this Section 5.12, shall have access to any unpublished accounting information or working papers other than those of Sellers and their direct or indirect subsidiaries.

5.13.	Post-Closing Title Review.

	5.13.1.	Within 60 days following the Closing Date, Buyer may conduct a review of the HPL Companies’ title to the real property interests described in Exhibit 5.13 to this Agreement, and assert Title Defects against Sellers, in accordance with the procedures set forth in this Section 5.13.

	5.13.2.	Prior to the expiration of the Defect Examination Period (as defined below), Buyer shall furnish to Sellers written notice(s) (each, a “Defect Notice”) specifying in reasonable detail each matter which, in Buyer’s opinion, constitutes a Title Defect (including any and all reasonable supporting documentation), and which Buyer wishes to assert as a Title Defect hereunder, together with the costs that Buyer, in good faith, estimates to be the costs necessary to cure or remediate the described Title Defects (each a “Defect Amount”). The “Defect Examination Period” shall mean the period commencing on the Closing Date and ending 30 days after such date. Any Title Defects not asserted by Buyer on or before the expiration of the Defect Examination Period in accordance with this Section 5.13 shall be deemed conclusively to be waived. Sellers shall have no liability for any Defect Amount unless such Defect Amount exceeds $50,000 (a “Qualifying Defect Amount”) and until and unless the sum of all Qualifying Defect Amounts exceeds $1,000,000 (the “Title Threshold”) and then only to the extent that such sum exceeds the Title Threshold, and Sellers’ liability therefor is subject to the Sellers’ Cap.

	5.13.3.	Sellers shall provide a written response to Buyer within 30 days following the expiration of the Defect Examination Period stating, with respect to each Title Defect asserted in the Defect Notice(s), whether or not Sellers agree: (a) that the alleged Title Defect constitutes a Title Defect under the terms of this Agreement; and (b) that Buyer’s estimate of the Defect Amount attributable to each Title Defect asserted by Buyer is acceptable to Sellers (the “Response Notice”). If Sellers disagree with Buyer’s assertion of the existence of a Title Defect or the Defect Amount with respect thereto, Sellers’ Response Notice shall also specify in reasonable detail Sellers’ grounds for such disagreement, the Defect Amount estimated in good faith by Sellers therefor, or both, as the case may be. If Sellers do not include in their Response Notice an objection to a Title Defect or to the Defect


Purchase and Sale Agreement		Page 40

		Amount, or if Sellers’ Response Notice agrees that the alleged Title Defect constitutes a Title Defect under the terms of this Agreement and that Buyer’s estimate of the Defect Amount is acceptable, then that Defect Amount shall be the amount taken into consideration under Section 5.13.2, regardless of the costs that Buyer in fact incurs in curing that Title Defect. Sellers and Buyer will attempt in good faith to resolve any disagreements with respect to the matters set forth in Buyer’s Defect Notice(s) and Sellers’ Response Notice within 30 days following Buyer’s receipt of Sellers’ Response Notice. If Sellers and Buyer are unable, within such 30 day period, to agree in writing as to the existence or value, as applicable, of any Title Defect, the parties agree to submit the dispute to the Independent Accounting Firm, which shall employ persons who are independent of the parties hereto and are impartial and experienced in the evaluation of matters of the type to be determined. The decision of the Independent Accounting Firm with respect to the disputed matters shall be final and binding on the parties. The parties will direct the Independent Accounting Firm to render its decision with respect to such matters within 15 days after the dispute is submitted, or such reasonably longer period as the Independent Accounting Firm requires in its reasonable discretion. Sellers and Buyer will each promptly provide all information and documents within their respective possession that the Independent Accounting Firm requests in order to make its decision with respect to the disputed matters. The fees of the Independent Accounting Firm will be borne equally by Sellers, on the one hand, and Buyer, on the other hand.

	5.13.4.	With respect to each Title Defect that has a Qualifying Defect Amount, Sellers may, at their election, either remit to Buyer such Qualifying Defect Amount (after satisfaction of the Title Threshold) or at Sellers’ sole cost and expense, and subject to the prior consent of Buyer (such consent not to be unreasonably withheld), cure within the Cure Period (as hereinafter defined) such Title Defect asserted by Buyer for which Sellers are liable hereunder. The “Cure Period” shall mean the period of time commencing on the expiration of the Defect Examination Period and ending 180 days after such date. Immediately following the expiration of the Cure Period, Sellers shall provide Buyer with written evidence of any curative actions which, in Sellers’ determination, cure the Title Defect. On or before the expiration of 15 days following Buyer’s receipt of such notice, Buyer shall provide to Sellers in writing a list of those Title Defects asserted by Buyer which Sellers claim to have cured pursuant to this Section, and which Buyer determines not to have been cured. For a period of 30 days after Sellers’ receipt of Buyer’s notice of uncured Title Defects, Sellers and Buyer shall attempt in good faith to resolve disputes as to such items by agreement. In the event that the dispute concerning any uncured Title Defect is not resolved within this 30 day period, then parties are unable to resolve all disputes concerning the existence of Title Defects or Defect Amounts within this 30 day period, then Sellers shall remit to Buyer the Qualifying Defect Amount for such uncured Title Defect (after satisfaction of the Title Threshold).


Purchase and Sale Agreement		Page 41

5.14.	Distributions to HPL Consolidation’s Partners.

	During the period from the Closing Date through and including the Valuation Time, Buyers will not cause or allow HPL Consolidation to make any distributions to its partners.

5.15.	Agreement to Cover Open Positions.

	In the event that either party determines, within 30 days following the Closing Date, that any Fixed Price Risk as of the end of the trading day immediately before the Closing Date is not hedged as of the Valuation Time, Sellers shall cause AEP Energy Services, Inc. to provide (and Buyer will cause ETC Marketing, Ltd. to accept) offsetting hedges to said Fixed Price Risk from the Closing Date. The obligation of Sellers to provide offsetting hedges shall not apply to volume variances during February 2005 in the normal course of business.

	(c)	Sellers’ indemnification obligations set forth in Section 6.2.1(vi) shall be limited such that Sellers shall only be liable thereunder to the extent that a written claim describing the nature of the claim, the theory of liability, or the nature of the relief sought and the material factual assertions upon which the claim is based is given to Sellers within 18 months following the Closing Date.

	(d)	Sellers’ indemnification obligations set forth in Section 6.2.1(iii) shall be limited such that Sellers shall only be liable thereunder to the extent that a written claim describing the nature of the claim, the theory of liability, or the nature of the relief sought and the material factual assertions upon which the claim is based is given to Sellers within 90 days after the expiration of the applicable statute of limitations.

	(e)	No reimbursement or payment for any Damages asserted against Sellers under Section 6.2.1(i) (other than for breach of Sellers’ representations and warranties set forth in Sections 3.1, 3.2.1, 3.2.2, 3.4, 3.6, and 3.9.2, which are not subject to the Sellers’ Threshold) or 6.2.1(v) shall be required unless and until the cumulative aggregate amount of such Damages for all claims

	(f)	Notwithstanding anything to the contrary contained in this Agreement, Sellers’ aggregate liability to Buyer and its Affiliates for all Damages under Sections 6.2.1(i) (other than for breaches of Sellers’ representations and warranties set forth in Section 3.6, which are not subject to Sellers’ Cap), 6.2.1(v), and 6.2.1(vi) and those items of Sellers’ Retained Matter Responsibility that are shown in Sellers’ Disclosure Schedules to be subject to Sellers’ Cap shall not exceed $220,000,000 (“Sellers’ Cap”).

	(i)	Sellers shall only be liable to the extent that a claim is provided to Sellers in a reasonably detailed written communication prior to the first anniversary of the Closing Date and Buyer shall afford Sellers a reasonable opportunity to evaluate the conditions giving rise to such claim.

	(ii)	Sellers shall not be responsible for any Damages that arise out of any action to meet a cleanup or remedial standard under any Environmental Law that is more stringent or costly than necessary for the continued ownership or use of any property or facility as it was last owned or used by the HPL Entities prior to the Closing Date in compliance with Environmental Laws applicable as of the Closing Date.

	(iii)	Sellers shall not be responsible for any costs of any post-Closing construction, demolition, or renovation of any facilities owned, leased, or operated by the HPL Entities including any asbestos abatement obligations arising from such activities, except to the extent that such activities are required to comply with Applicable Law, and such non-compliance was a breach under Section 3.18.

Buyer Indemnified Parties shall cause the HPL Entities to afford Sellers reasonable access to any relevant property or facility to undertake any such investigation, remediation or other action (it being understood that if Sellers do not assume responsibility for undertaking actions pursuant to this subsection, Buyer Indemnified Parties may undertake to complete such actions in a reasonably cost effective manner, and Sellers shall have a right to reasonable participation in such undertaking). Sellers will promptly repair and restore any damage to the property of an HPL Entity caused by Sellers in connection with any such investigation, remediation, or other action as close as reasonably practicable to the former condition of such property, and Sellers will indemnify Buyer and the HPL Entities from and against any Damages related to or arising from Sellers’ or their agents’ or employees’ performance of the remediation work or their presence on the premises of Buyer or the HPL Entities.

Except as otherwise set forth in Section 6.2, Buyer shall give Sellers 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 Sellers shall have the right to assume the defense of any such claim through counsel of their own choosing, by so notifying Buyer within 60 days of receipt of Buyer’s written notice under this paragraph; provided, however, that Sellers’ 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 any such defense assumed by Sellers, it may do so at its sole cost and expense but Sellers shall retain control of any assumed defense. If Sellers decline to assume any such defense, they shall be liable for all reasonable costs and expenses of defending such claim incurred by Buyer, including reasonable fees and disbursements of counsel.


Purchase and Sale Agreement		Page 46

6.2.5.

Sellers shall have no indemnification obligation to Buyer with respect to any Damages arising from or relating to the condition, remaining useful life, or structural integrity of the pipeline or gas storage assets (or related equipment or facilities) of the HPL Entities unless such Damages arise out of Sellers’ breach of a representation or covenant in this Agreement.

	(a)	Buyer’s indemnification obligations under Section 6.3.1(i) shall be subject to the Survival Period limitations set forth in Section 6.1.

	(b)	No reimbursement or payment for any Damages asserted against Buyer under Sections 6.3.1(i) or 6.3.1(iii) shall be required unless and until the cumulative aggregate amount of such Damages for all claims arising thereunder equals or exceeds $10,000,000 (the “Buyer’s Threshold”) and then only to the extent that the cumulative aggregate amount of Damages, as finally determined, exceeds the Buyer’s Threshold.

	(c)	Notwithstanding anything to the contrary contained in this Agreement, Buyer’s liability to Seller Indemnified Parties for Damages in excess of Buyer’s Threshold under Section 6.3.1(i) shall not exceed $220,000,000 (“Buyer’s Cap”).

If Sellers desire to participate in any such defense assumed by Buyer they may do so at their 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 Sellers, 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 parties or any 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.

	6.3.4.	The indemnities provided in this Section 6.3 shall survive the Closing. The indemnity provided in this Section 6.3 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 6.3.1.

6.4. Indemnification Net of Benefits; Mitigation Obligations of Indemnitee.

The Damages recoverable by any Indemnified Party under this Article 6 shall be calculated after giving effect to the actual receipt of any available insurance proceeds, third party indemnification or contribution payment, or other similar right of recovery (collectively, “Recoveries”) paid or payable to the Indemnified Party. In computing the amount of any Recovery, (i) such Recovery shall be reduced by a reasonable estimate of the present value of future insurance premium increases that the Indemnified Party may reasonably expect to bear to the extent attributable to the payment of insurance proceeds included in the Recovery and (ii) insurance proceeds which are ultimately borne by the Indemnified Party under any self-insurance, retrospective premium, deductible or comparable arrangement shall not be taken into account. In all cases in which a Person is entitled to be indemnified under this Article 6, such Indemnified Party shall be under a duty to take all commercially reasonable measures to mitigate all such Damages.

7.	TAX MATTERS

7.1.	Tax Indemnification.

7.1.1.

Purchase and Sale Agreement		Page 48

		Companies with regard (x) to all taxable periods ending as of or prior to the Closing Date (the “Pre-Closing Period”) (y) with respect to any Tax period beginning prior to the Closing and ending after the Closing (the “Straddle Period”), the portion of Taxes attributable to the portion of such taxable period beginning before (but not ending on) the Closing Date shall be calculated as though the tax year terminates as of Closing; 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 taxable period multiplied by a fraction, the numerator of which shall be the number of days from the beginning of the taxable period up to but not including the Closing Date and the denominator of which shall be the total number of days in the taxable period; and (ii) all Taxes arising out of or related to a breach of any of the representations and warranties set forth in Section 3.16 of this Agreement.

	7.1.2.	Except for any Liabilities associated with Sellers’ Retained Interest in each HPL Entity after the Closing and any Liabilities for which Sellers are required to indemnify Buyer under Section 7.1.1 hereof, Buyer shall indemnify and hold Sellers and each of their Affiliates harmless from and against any and all Taxes of, or pertaining or attributable to, the HPL Entities with respect to any taxable period that begins on or after the Closing.

7.2.	Preparation and Filing of Tax Returns.

7.2.1.

With respect to any Tax which is based on federal income, any Tax election relating thereto, and with respect to any Tax accounting method, for any Pre-Closing Period, Sellers, without the consent of Buyer, shall be entitled to file any amended Tax Return with respect to any Tax which Sellers deem appropriate, as determined in Sellers’ sole discretion, provided that no filing may change the status of any HPL Companies as disregarded entities for federal income tax purposes. For all other Taxes, either Buyer or Sellers, as appropriate, shall be entitled to file an amended Tax Return provided that: (i) Buyer may not amend a Tax Return in such a manner that would cause Sellers to have any indemnification obligations under Section 7.1.1 hereof, and further provided that no filing may change the status of any HPL Companies as disregarded entities for federal income tax purposes for any Pre-Closing Period, and (ii) Sellers may not amend any Tax Return for a Tax not based on income without the consent of Buyer which consent shall not be unreasonably withheld. To the extent not made for previous tax years, Sellers agree to make a timely and valid 754 election for MidTexas Pipeline Company for the period ending December 31, 2004. Sellers shall prepare or cause to be prepared and file or cause to be filed all Tax Returns for the HPL Companies for all Pre-Closing Periods, and shall pay all Taxes due with respect to such Tax Returns except to the extent that the liability for such Taxes is included as a liability in the computation of Net Working Capital.

7.2.2.

Buyer and Sellers 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 any deadline imposed by this Agreement on Buyer or Sellers 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 will be extended as appropriate in light of any party’s failure to promptly make such assistance available, 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 7.2.2 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 hereto in accordance with Section 8.2.

7.3.	Procedures Relating to Indemnification of Tax Claims.

	7.3.1.	If a claim regarding liability for a Tax or with respect to a Tax Return shall be made by any Governmental Authority, for which Sellers are or may be liable pursuant to this Agreement, Buyer shall notify Sellers in writing within 10 Business Days of receipt by Buyer of notice of such claim (a “Tax Claim”).

	7.3.2.
