        (b)   If this Agreement is not terminated by BUYER as provided in subsection (a), BUYER's sole remedy with respect to any Casualty Loss in respect of Assets which are not repaired or replaced prior to the Closing is to (i) reduce the Purchase Price by an amount estimated by DEFS and agreed to by BUYER to be equal to the repair or replacement cost of the Assets affected by the Casualty Loss; provided that, if the Parties cannot agree, then the Closing shall occur and either Party may submit the determination of the costs of the Casualty Loss for resolution pursuant to Section 12.8, in which case any insurance, condemnation or taking proceeds with respect to such Casualty Loss shall be the sole property of DEFS, or (ii) accept the Assets with no adjustment to the Purchase Price, but with BUYER being entitled to receive as BUYER's sole property all insurance, condemnation or taking proceeds, on account of such Casualty Loss.

        7.3    Access, Information and Access Indemnity.

        (ii)   Agree to pay to BUYER an amount for the Environmental Defect equal to the Environmental Corrective Cost thereof as agreed to between DEFS and BUYER; provided that if the Parties are unable to agree, the Closing shall occur and such amount shall be determined by arbitration pursuant to the procedure in Section 12.8; or

        (iii)  If such Environment Defect is of the kind or nature that a prudent operator of assets like the Assets affected by such Environmental Defect would not currently undertake Remediation, agree to indemnify BUYER against Claims and Losses related to the Environmental Defect in accordance with Section 11.2(e), in which case such item shall be set forth on Schedule 11.2(e).

21

        (d)   Notwithstanding anything in this Section 7.4 to the contrary, BUYER shall not be entitled to assert any Environmental Defect under this Agreement, and hereby waives all Claims against DEFS with respect to any Environmental Matters, unless the reasonably estimated Environmental Corrective Costs of such Environmental Defect exceed $5,000 (a "Qualified Environmental Claim") and then only to the extent that the sum of all such Qualified Environmental Claims exceeds $250,000 in the aggregate.

        (e)   In connection with any Environmental Defect that DEFS is required to Remediate or indemnify BUYER under this Agreement, (i) BUYER shall make available, and DEFS shall have the right, from time to time, to review, all environmental materials related to the Assets to the extent related to any Pre-Closing environmental issues, and to have access to the Assets and BUYER's utility services from time to time to effect Remediation, (ii) BUYER shall in good faith fully cooperate with DEFS with respect thereto and (iii) DEFS shall have the sole and exclusive right to conduct any Remediation; provided, however, BUYER shall be entitled to participate with DEFS in any discussions, negotiations and Proceedings with any Governmental Authorities in connection therewith.

DEFS shall comply fully with all rules, regulations, policies and instructions issued by BUYER or any Third Person operator regarding DEFS' actions while upon, entering or leaving any property included in the Assets, including any insurance requirements to the extent set forth on Schedule 7.4(e). Notwithstanding the foregoing, BUYER shall not impose rules, regulations or instructions that unreasonably impede or delay DEFS' Remediation activities.

        (f)    If (i) Environmental Corrective Costs with respect to any Environmental Defects affecting the AIM System exceeds $3,500,000, and (ii) notwithstanding that such Environmental Defects would be Remediated by DEFS pursuant to this Agreement, such Environmental Defects could reasonably be expected to have a material adverse effect on the value of the AIM System, BUYER shall have the right to terminate this Agreement upon ten (10) days written notice to DEFS, which notice shall describe in reasonable detail BUYER's basis for concluding that such a material adverse effect exists notwithstanding that such Environmental Defect would be Remediated by DEFS.

        (g)   Notwithstanding anything in this Agreement to the contrary, (i) BUYER shall accept all liability and obligations with respect to any ground coverage conditions on the following segments of the AIM System: the Ray Braswell-Pineywoods 20" line located in the Springwood Subdivision, the Vicksburg (Halls Ferry Road) 12" line and the Baxterville 16" line, and (ii) DEFS shall accept all liability and obligations with respect to, and use commercially reasonably efforts to remedy prior to Closing, the ground coverage conditions on the Redwood line comprising part of the AIM System existing prior to the Closing and those matters described in items 3(c), (d) and (e) of Schedule 5.13 and item 3(b) on Schedule 5.7. If DEFS is unable to remedy such matters prior to Closing, DEFS shall treat such matters as if they were Environmental Defects that DEFS had agreed to Remediate, provided, however, that BUYER shall make its field personnel available to DEFS to assist in the remediation of the Redwood line ground coverage condition at no cost and DEFS shall have no liability to BUYER for ground coverage gas loss or for disruption to BUYER's operations as a result of remediation of such ground coverage conditions. DEFS shall

22

consult with BUYER with respect to its proposed remediation of the Redwood line washout conditions.

        (b)   With respect to Title Defects that are described in a Title Defect Notice delivered to DEFS by the Title Notice Deadline, DEFS shall, in its sole discretion, elect either one of the following by written notice prior to the Closing:

        (c)   Notwithstanding anything in this Section 7.5 to the contrary, BUYER shall not be entitled to assert any Title Defect under this Agreement, and hereby waives all Claims against DEFS in respect of any Title Defects, unless the Claim is timely made in accordance with the provisions of this Section 7.5 and then only to the extent that the Title Corrective Costs with respect to all such Title Defects exceed $100,000 in the aggregate.

        (e)   Except as a result of the special warranty of title described in Section 2.1 and contained in each bill of sale or other conveyance document transferring or conveying the Assets to BUYER and DEFS' indemnity obligations under Section 11.2(e) (which shall not be limited by the provisions of this Section 7.5), this Section 7.5 sets forth BUYER's sole and exclusive remedy with respect to Title Defects or any other title conditions or other title matters affecting the Assets.

23

together with any reductions in the Purchase Price as a result of any Casualty Losses and DEFS' good faith estimate of its liability with respect to breaches of representations and warranties of which DEFS has received notice from BUYER, exceeds 5% of the Purchase Price, then DEFS shall have the right to terminate this Agreement upon ten (10) days written notice to BUYER.

        7.7    Names.    As soon as reasonably possible, but in no event later than sixty (60) days after Closing, BUYER shall remove the names of DEFS and its Affiliates, including "Duke" or "DEFS" and all variations thereof, from the Assets.

        (a)   BUYER and DEFS will take all commercially reasonable actions necessary or desirable, and proceed diligently and in good faith and use all commercially reasonable efforts, as promptly as practicable to obtain all consents, approvals or actions of, to make all filings with, and to give all notices to, Governmental Authorities required to accomplish the transactions contemplated by this Agreement.

        (b)   This Agreement is subject in all respects to and conditioned upon compliance by the Parties with the HSR Act, to the extent that the HSR Act is applicable to the transactions contemplated by this Agreement. The Parties shall make any filings required under the HSR Act on or prior to fifteen (15) days after the date hereof and provide such information to the FTC as is required in connection with the HSR Act as soon as practicable after a request therefor.

        (c)   Notwithstanding any provision herein to the contrary, each of the Parties will (i) use reasonable efforts to comply as expeditiously as possible with all lawful requests of Governmental Authorities for additional information and documents pursuant to the HSR Act, (ii) not (A) extend any waiting period under the HSR Act or (B) enter into any voluntary agreement with any Governmental Authority not to consummate the transactions contemplated by this Agreement, except with the prior consent of the other Party, and (iii) cooperate with each other and use reasonable efforts to obtain the requisite approval of the FTC and DOJ; provided, however, that neither Party shall be obligated to accept any conditional approval or divest any of its properties (including, in the case of the BUYER, any of the Assets).

        (d)   BUYER will be responsible for paying the filing fees required with respect to any filing under the HSR Act.

        7.9    Preservation of Records.    For a period of seven (7) years after the Closing Date, the Party in possession of the originals of the Records will retain such Records at its sole cost and expense and will make such Records available to the other Party upon reasonable notice for inspection and/or copying, at the expense of the requesting Party, at the headquarters of the Party in possession (or at such other location in the United States as the Party in possession may designate in writing to the other Party) at reasonable times and during regular office hours. If BUYER, at any time, transfer(s) the Assets directly or indirectly, to a Third Person, then BUYER will provide notice of such transfer to DEFS within a reasonable period after such transfer and obligate the transferee to maintain the Records as herein required and will retain access to the Records for the benefit of itself and DEFS. BUYER agrees that DEFS may retain a copy of the Records.

24

        7.11    Imbalances.      

        (a)   Schedule 1.1(a) sets out the actual amounts of the Assumed Imbalance Receivables and the Assumed Imbalance Payables as of the date set forth in such schedule. DEFS shall use commercially reasonable efforts to minimize the amount of the Assumed Imbalance Receivables and the Assumed Imbalance Payables outstanding as of the Effective Time. DEFS shall make a good faith estimate of the Assumed Imbalance Receivables and Assumed Imbalance Payables as of the date five (5) days prior to the Closing Date and update Schedule 1.1(a) to reflect such estimate. The Assumed Imbalance Receivables as set out in the final Schedule 1.1(a) shall be for the sole benefit of BUYER and it shall be the sole obligation of BUYER to discharge the Assumed Imbalance Payables as set out in the final Schedule 1.1(a). Such amounts shall be cashed out as between the Parties based upon the formula used to value the Excess Inventory. BUYER and DEFS agree to cooperate and to make available to each other all information necessary to calculate and to confirm and verify the actual volume and value of Imbalances.

        (b)   DEFS shall retain any and all such Imbalances other than the Assumed Imbalance Receivables and the Assumed Imbalance Payables. BUYER shall use reasonable good faith efforts to assist DEFS (as DEFS may reasonably request) in collecting such amounts and pay to DEFS any such amounts (and the market value of any Imbalance delivered in kind) that BUYER collects or receives.

        (a)   Certain funds otherwise payable to operators and/or working, royalty or other interest owners in wells connected, or other owners delivering natural gas or liquid hydrocarbons to certain facilities have been or may be placed in suspense pending resolution of questions of title, execution of division or transfer orders, or for similar reasons (the "Suspense Account Funds"). DEFS shall retain any and all Suspense Account Funds and related obligations other than with respect to the Assumed Suspense Account Obligations.

        (b)   Schedule 1.1(b) sets out the actual liability in respect of the Assumed Suspense Account Obligations as of the date set forth in such Schedule. DEFS shall make a good faith estimate of its liability in respect of the Assumed Suspense Account Obligations as of the date five (5) days prior to the Closing Date, shall update Schedule 1.1(b) to reflect such estimate, and in exchange for a payment in an amount equal to such estimated liability, BUYER shall assume and agree to be solely responsible for such scheduled liabilities. BUYER and DEFS agree to cooperate and to make available to each other all information necessary to calculate and to confirm and verify the actual amount of the liability with respect to the Assumed Suspense Account Obligations.

        7.13    Capital Projects.    Schedule 7.13 as supplemented from time to time sets out those capital projects ("Capital Projects") for which BUYER shall have financial responsibility. DEFS shall have the right to supplement Schedule 7.13 to add non-maintenance related capital projects approved by BUYER pursuant to Section 7.1(a)(iv) or for which BUYER does not have approval rights because they do not meet the size to require approval pursuant thereto. BUYER shall reimburse DEFS at the Closing for DEFS' actual costs paid in connection with the Capital Projects identified in Schedule 7.13, whether or not DEFS has received an invoice therefore. All costs and expenses in respect of the Capital Projects incurred after the Effective Time shall be solely for the account of and payable by BUYER.

25

        7.14    Employees.      

        (a)   Within ten (10) days from the date of this Agreement, DEFS will provide BUYER with a list of all field employees and commercial and administrative support employees of DEFS and its Affiliates who are assigned on a full time or primary basis to any of the Assets (the "Business Employees") and, with respect to each Business Employee, the Business Employee's name, title, and compensation.

        (b)   BUYER, at its sole option and discretion, may make offers of employment to those Business Employees selected by BUYER. Subject to the terms of this Agreement, BUYER's offers of employment shall be on such terms and conditions (including levels of compensation) as BUYER may determine in its sole discretion.

        (c)   BUYER may conduct pre-employment interviews with the Business Employees and DEFS shall provide reasonable access to such employees to BUYER to conduct such interviews. No later than thirty-five (35) days after the date hereof, BUYER will deliver to DEFS a written list containing the name and proposed offer (including base pay and benefits) of all of the Business Employees to whom BUYER intends to offer employment. The Business Employees who accept and actually commence employment with BUYER on the Closing Date (unless DEFS and BUYER mutually agree to a later commencement date) are hereinafter collectively referred to as the "Continuing Employees."

        (d)   With respect to any employees of DEFS or its Affiliates who perform services with respect to any of the Assets and whose employment relationship with DEFS or any of its Affiliates is terminated by DEFS, DEFS shall comply with all applicable Laws in connection therewith, including the Worker Adjustment and Retraining Notification Act.

        (e)   With respect to the Continuing Employees:

        (i)    If BUYER terminates the employment of any Continuing Employee within one (1) year after the Closing Date under circumstances that would have entitled such Continuing Employee to a severance benefit under DEFS' severance formula in effect for such employee on the Effective Time, as described on Schedule 7.14(e)(i), BUYER will pay such Continuing Employee severance based on such severance benefit plan taking into account years of service recognized by DEFS and years of service with BUYER. DEFS shall provide BUYER prior to Closing with a schedule setting out the severance benefits payable under the DEFS severance benefit plan for each Continuing Employee.

        (ii)   The Continuing Employees shall be eligible to participate in BUYER's benefit plans in accordance with the terms thereof. To the extent permitted by Law and BUYER's benefit plans, and without regard to whether such employees are located outside of the region of any network providing coverage under any such plans, (A) BUYER shall grant all Continuing Employees credit for their service with DEFS or its Affiliates for purposes of eligibility to participate in and vesting credits in BUYER's severance, long term disability, service award, vacation programs and policies, and retirement plans, (B) for the year during which such coverage begins, BUYER shall credit under any medical and/or dental benefit plan maintained by BUYER all Continuing Employees with any deductibles and co-payments already incurred during such year under DEFS' (or its Affiliate's) group health plan, and waive any pre-existing conditions exclusions or limitations as to coverage, any evidence-of-insurability provisions, and any waiting-period requirements under such plans, and (C) BUYER shall apply towards any deductible requirements and out-of-pocket maximum limits under such BUYER welfare benefit plans that are applicable for the plan year in which the Closing occurs, any amounts paid by a Continuing Employee toward such requirements and limits under any similar DEFS welfare Benefit Plan. As soon as reasonably practicable

26

after the Closing, DEFS shall prepare and deliver to each Continuing Employee and request such Continuing Employee to deliver to BUYER a schedule setting forth the amount of the deductible and out-of-pocket maximum limits satisfied by such Continuing Employee under DEFS welfare Benefit Plans as of the Closing.

        (iii)  As soon as administratively feasible after the Closing, and subject to reasonable requirements, BUYER shall cause the trustee of BUYER's 401(k) plan trust to accept direct rollovers from DEFS' 401(k) plan trust for each Continuing Employee electing the same with respect to a distribution of his or her vested account thereunder. In addition, participant promissory notes for any outstanding loans of Continuing Employees under DEFS' 401(k) plan shall be rolled over to BUYER's 401(k) plan trust, to the extent permitted by Law, DEFS' 401(k) plan and BUYER's 401(k) plan. If any Continuing Employee does not rollover his or her account to BUYER's 401(k) plan, such Continuing Employee may continue to participate in DEFS' 401(k) plan as a terminated participant in accordance with the terms thereof, and DEFS shall retain all responsibility for the management and administration of such Continuing Employee's account balances under DEFS' 401(k) plan.

        (iv)  The number of vacation days that each Continuing Employee shall be entitled under BUYER's vacation policies for calendar year 2003 shall not exceed the number of remaining vacation days to which such employee has been granted for calendar year 2003 under DEFS' vacation policies determined as of the Effective Time, which such employee has not used and for which such employee has not been paid by DEFS. Promptly following the Closing, DEFS shall provide BUYER with a written exhibit showing the number of remaining vacation days for each Continuing Employee.

        (f)    For the one-year period following the Closing Date, if BUYER or any of its Affiliates directly or indirectly (including as an employee, a contractor or an employee of a contractor or subcontractor) retains the services of any of any Business Employee to whom DEFS paid severance payments or benefits because the employment of such Business Employee with DEFS was terminated within 60 days of the Effective Time, BUYER shall immediately reimburse DEFS the actual amount or value of severance pay that DEFS paid to such Business Employee. Notwithstanding the foregoing, this Section 7.14(f) shall not apply to employees of contractors or subcontractors of BUYER who are performing similar services for customers other than BUYER and its Affiliates.

        7.15    Like-kind Exchange.    So long as it does not delay the Closing and DEFS pays the transaction costs for such exchange, DEFS shall have the right at any time prior to Closing to assign all or a portion of its rights (but not its obligations) under this Agreement to a qualified intermediary in order to accomplish the transactions contemplated by this Agreement in a manner that would comply, either in whole or in part, with the requirements of a like-kind exchange pursuant to Section 1031 of the Code. If DEFS assigns its rights under this Agreement for this purpose, DEFS shall provide BUYER with prior written notice and BUYER agrees that, if so requested by DEFS, it will (a) provide a written consent to DEFS' assignment of its rights in this Agreement for the sole purpose herein described, and (b) pay the Purchase Price into a qualified escrow or qualified trust account at Closing as directed in writing by DEFS. Any assignment of this Agreement to a qualified intermediary shall not release DEFS from any of its liabilities or obligations to BUYER under this Agreement. DEFS shall be solely responsible to designate and obtain exchange property and to otherwise comply with Section 1031 of the Code. The rights of the Parties shall not be affected by any determination that the transaction does not qualify as a like-kind exchange.

        7.16    Credits and Receipts.    Subject to the terms hereof (including the indemnification provisions hereof), all monies, proceeds, receipts, credits and income attributable to the Assets (as determined in accordance with GAAP) (i) for all periods of time at and after the Effective Time, shall be the sole

27

property and entitlement of BUYER, and, to the extent received by DEFS or one of its Affiliates, shall be promptly accounted for and transmitted to BUYER and (ii) for all periods of time prior to the Effective Time, shall be the sole property and entitlement of DEFS and, to the extent received by BUYER, shall be promptly accounted for and transmitted to DEFS. After Closing, regardless of when and by whom the actual invoice or demand for payment is received, (a) DEFS shall pay and be responsible for all Retained Liabilities and (b) BUYER shall pay and be responsible for all Assumed Liabilities.

        7.17    Cooperation and Reasonable Efforts.    The Parties agree to cooperate with each other and to use commercially reasonable efforts to cause all of the conditions precedent to Closing to be satisfied as soon as practicable.

        7.18    Financial Statements.    As soon as practicable after the execution of this Agreement, BUYER shall seek approval from the Securities Exchange Commission to file limited audited financial statements for the Assets consisting solely of a statement of revenue and direct operating expenses for the years ending December 31, 2000, December 31, 2001 and December 31, 2002 and the three month period ended March 31, 2003 and 2002, and, if necessary, the six month period ended June 30, 2003 and 2002 ("Limited Financials"). A public accounting firm of BUYER's choice will perform an audit of the Limited Financials and DEFS shall undertake reasonable efforts to facilitate (and shall cause the Selling Subsidiaries to undertake reasonable efforts to facilitate) such audit as requested by BUYER. In the event that BUYER is unable to obtain the consent of the Securities Exchange Commission to file the Limited Financials, then the parties shall negotiate in good faith a resolution that will allow BUYER to file that required by the Securities Exchange Commission and compensate DEFS for all associated internal and external costs.

        (a)   Subject to this Section 11.3, all representations, warranties, covenants and indemnities made by the Parties in this Agreement or pursuant hereto shall survive the Closing as hereinafter provided, and shall not be merged into any instruments or agreements delivered at Closing.

        (b)   With respect to the obligations of DEFS:

        (i)    Under Section 11.2(a):

(A)

none of the BUYER Indemnitees shall be entitled to assert any right to indemnification after two (2) years from the Effective Time;



(B)

none of the BUYER Indemnitees shall be entitled to assert any right to indemnification unless the individual claim or series of related claims which arise out of substantially the same facts and circumstances exceed $25,000;



(C)

none of the BUYER Indemnitees shall be entitled to assert any right to indemnification unless such claims in the aggregate exceed $500,000, and then only to the extent that all such claims exceed said amount; and



(D)

none of the BUYER Indemnitees shall be entitled to assert any right to indemnification to the extent such claims exceed in the aggregate 50% of the Purchase Price.

        (ii)   None of the BUYER Indemnitees shall be entitled to assert any right to indemnification under Section 11.2(c) or Section 11.2(d) after two (2) years from the Effective Time.

        (c)   The claim for indemnity under this Agreement made by a Party Indemnitee shall be in writing, be based upon a Claim that is actually asserted (and, with respect to a BUYER Indemnitee, be delivered in good faith prior to the respective survival period under Section 11.3(b)), and specify in reasonable detail the specific nature of the Claim for indemnification hereunder ("Claim Notice"). Any such claim that is described in a timely delivered Claim Notice (and substantially related claims arising out of the same facts or circumstances) shall survive with respect to the specific matter described therein; provided, however, that any such

32

claim by any BUYER Indemnitee involving an Environmental Defect or any Environmental Matter shall terminate at the earlier of:

        (i)    the time that DEFS receives closure from a Governmental Authority of the respective Environmental Defect; or

        (ii)   365 days have lapsed after DEFS provided notice of completion of such cleanup activity to the Governmental Authority that has actually asserted jurisdiction over such matter.

        (d)   Notwithstanding anything contained herein to the contrary, in no event shall DEFS be obligated under this Agreement to indemnify (or be otherwise liable hereunder in any way whatsoever to) any of the BUYER Indemnitees with respect to a breach of any representation or warranty, if BUYER had Knowledge thereof at Closing and failed to notify DEFS of such breach prior to Closing pursuant to Section 7.17.

        (e)   Notwithstanding anything contained herein to the contrary, all of BUYER's covenants, representations, warranties, indemnity obligations and other obligations under this Agreement shall be perpetual.

        11.4    Notice of Asserted Liability; Opportunity to Defend.      

        (a)   All claims for indemnification hereunder shall be asserted and handled pursuant to this Section 11.4. Any person claiming indemnification hereunder is referred to herein as the "Indemnified Party" or "Indemnitee" and any person against whom such claims are asserted hereunder is referred to herein as the "Indemnifying Party" or "Indemnitor."

        (b)   In the event that any Claim is asserted against or any Loss is sought to be collected from an Indemnifying Party, the Indemnified Party shall with reasonable promptness provide to the Indemnifying Party a Claim Notice. The failure to give any such Claim Notice shall not otherwise affect the rights of the Indemnified Party to indemnification hereunder unless the Indemnified Party has proceeded to contest, defend or settle the Claim or remedy a Loss with respect to which it has failed to give a Claim Notice to the Indemnifying Party. Additionally, to the extent the Indemnifying Party is prejudiced thereby, the failure to provide a Claim Notice to the Indemnifying Party shall relieve the Indemnifying Party from liability for such Claims and Losses that it may have to the Indemnified Party, but only to the extent the liability for such Claims or Losses is directly attributable to such failure to provide the Claim Notice.

        (c)   The Indemnifying Party shall have thirty (30) days from the personal delivery or receipt of the Claim Notice (the "Notice Period") to notify the Indemnified Party (i) whether or not it disputes the liability to the Indemnified Party hereunder with respect to the Claim or Loss, and in the event of a dispute, such dispute shall be resolved in the manner set forth in Section 12.8 hereof, (ii) in the case where Losses are asserted against or sought to be collected from an Indemnified Party by the Indemnified Party, whether or not the Indemnifying Party desires at its own sole cost and expense to attempt to remedy such Losses or (iii) in the case where Claims are asserted against or sought to be collected from an Indemnified Party by a Third Person ("Third Person Claim"), whether or not the Indemnifying Party desires at its own sole cost and expense to defend the Indemnified Party against such Third Person Claim; provided, however, that any Indemnified Party is hereby authorized prior to and during the Notice Period to file any motion, answer or other pleading that it shall deem necessary or appropriate to protect its interests or those of the Indemnifying Party (and of which it shall have given notice and opportunity to comment to the Indemnifying Party) and not prejudicial to the Indemnifying Party.

        (d)   If the Indemnifying Party does not give notice to the Indemnified Party of its election to contest and defend any such Third Person Claim within the Notice Period, then the Indemnifying

33

Party shall be bound by the result obtained with respect thereto by the Indemnified Party and shall be responsible for all costs incurred in connection therewith.

        (e)   If the Indemnifying Party is obligated to defend and indemnify the Indemnified Party, and the Parties have a conflict of interest with respect to any such Third Person Claim, then the Indemnified Party may, in its sole discretion, separately and independently contest and defend such Third Person Claim, and the Indemnifying Party shall be bound by the result obtained with respect thereto by the Indemnified Party and shall be responsible for all costs incurred in connection therewith.

        (f)    In the event that the Indemnifying Party notifies the Indemnified Party within the Notice Period that it desires to defend the Indemnified Party against Third Person Claim, the Indemnifying Party shall have the right to defend all appropriate Proceedings, and with counsel of its own choosing (but reasonably satisfactory to the Indemnified Party) and such Proceedings shall be promptly settled or prosecuted by it to a final conclusion. If the Indemnified Party desires to participate in, but not control, any such defense or settlement it may do so at its sole cost and expense. If the Indemnified Party joins in any such Third Person Claim, the Indemnifying Party shall have full authority to determine all action to be taken with respect thereto.

        (g)   If requested by the Indemnifying Party, the Indemnified Party agrees to cooperate with the Indemnifying Party and its counsel in contesting any Third Person Claim and in making any counterclaim against the Third Person asserting the Third Person Claim, or any cross-complaint against any person. No Third Person Claim may be settled or otherwise compromised without the prior written consent of the Indemnifying Party.

        (h)   At any time after the commencement of defense of any Third Person Claim, the Indemnifying Party may request the Indemnified Party to agree in writing to the abandonment of such contest or to the payment or compromise by the Indemnifying Party of the asserted Third Person Claim, but only if the Indemnifying Party agrees in writing to be solely liable for such Third Person Claim; whereupon such action shall be taken unless the Indemnified Party determines that the contest should be continued and notifies the Indemnifying Party in writing within fifteen (15) days of such request from the Indemnifying Party. In the event that the Indemnified Party determines that the contest should be continued, the amount for which the Indemnifying Party would otherwise be liable hereunder shall not exceed the amount which the Indemnifying Party had agreed to pay to compromise such Third Person Claim; provided that, the other Person to the contested Third Person Claim had agreed in writing to accept such amount in payment or compromise of the Third Person Claim as of the time the Indemnifying Party made its request therefor to the Indemnified Party, and further provided that, under such proposed compromise, the Indemnified Party would be fully and completely released from any further liability or obligation with respect to the matters which are the subject of such contested Third Person Claim.

        11.5    Exclusive Remedy.    AS BETWEEN THE BUYER INDEMNITEES AND THE DEFS INDEMNITEES, AFTER CLOSING (A) THE EXPRESS INDEMNIFICATION PROVISIONS SET FORTH IN THIS AGREEMENT AND THE TRANSACTION DOCUMENTS WILL BE THE SOLE AND EXCLUSIVE RIGHTS, OBLIGATIONS AND REMEDIES OF THE PARTIES WITH RESPECT TO SAID AGREEMENTS, THE EVENTS GIVING RISE THERETO, AND THE TRANSACTIONS PROVIDED FOR THEREIN OR CONTEMPLATED THEREBY AND (B) NEITHER PARTY NOR ANY OF ITS RESPECTIVE SUCCESSORS OR ASSIGNS SHALL HAVE ANY RIGHTS AGAINST THE OTHER PARTY OR ITS AFFILIATES OTHER THAN AS IS EXPRESSLY PROVIDED IN THIS AGREEMENT AND THE TRANSACTION DOCUMENTS.

        11.6    Negligence and Strict Liability Waiver.    WITHOUT LIMITING OR ENLARGING THE SCOPE OF THE INDEMNIFICATION OBLIGATIONS SET FORTH IN THIS AGREEMENT, AN INDEMNIFIED PARTY SHALL BE ENTITLED TO INDEMNIFICATION UNDER THIS

34

AGREEMENT IN ACCORDANCE WITH THE TERMS HEREOF, REGARDLESS OF WHETHER THE LOSS OR CLAIM GIVING RISE TO SUCH INDEMNIFICATION OBLIGATION IS THE RESULT OF THE SOLE, CONCURRENT OR COMPARATIVE NEGLIGENCE, STRICT LIABILITY, OR VIOLATION OF ANY LAW OF OR BY SUCH INDEMNIFIED PARTY.

        11.7    DTPA Waiver.    TO THE EXTENT APPLICABLE TO THE INTERESTS OR ANY PORTION THEREOF, BUYER HEREBY WAIVES ITS RIGHTS UNDER THE PROVISIONS OF THE TEXAS DECEPTIVE TRADE PRACTICES ACT, CHAPTER 17, SUBCHAPTER E, SECTIONS 17.41 THROUGH 17.63, INCLUSIVE (OTHER THAN SECTION 17.555, WHICH IS NOT WAIVED), OF THE TEXAS BUSINESS & COMMERCIAL CODE (A LAW THAT GIVES CONSUMERS SPECIAL RIGHTS AND PROTECTIONS). AFTER CONSULTATION WITH AN ATTORNEY OF ITS CHOICE, BUYER VOLUNTARILY CONSENTS TO THIS WAIVER.

        11.8    Limitation on Damages.    NOTWITHSTANDING ANYTHING TO THE CONTRARY IN THIS AGREEMENT, IN NO EVENT SHALL EITHER DEFS OR BUYER BE LIABLE TO THE OTHER, OR TO THE OTHER'S INDEMNITEES, UNDER THIS AGREEMENT FOR ANY EXEMPLARY, PUNITIVE, REMOTE, SPECULATIVE DAMAGE, AND EXCEPT FOR REMEDIES EXPRESSLY PROVIDED PURSUANT TO THE TERMS OF THIS AGREEMENT, ANY CONSEQUENTIAL (INCLUDING ANY LOSS OF THROUGHPUT ON THE ASSETS), SPECIAL OR INCIDENTAL DAMAGES OR LOSS OF PROFITS; PROVIDED THAT, IF ANY OF THE DEFS INDEMNITEES OR BUYER INDEMNITEES IS HELD LIABLE TO A THIRD PERSON FOR ANY SUCH DAMAGES AND THE INDEMNITOR IS OBLIGATED TO INDEMNIFY SUCH DEFS INDEMNITEES OR BUYER INDEMNITEES FOR THE MATTER THAT GAVE RISE TO SUCH DAMAGES, THE INDEMNITOR SHALL BE LIABLE FOR, AND OBLIGATED TO REIMBURSE SUCH INDEMNITEES FOR SUCH DAMAGES.

        11.9    Bold and/or Capitalized Letters.    THE PARTIES AGREE THAT THE BOLD AND/OR CAPITALIZED LETTERS IN THIS AGREEMENT CONSTITUTE CONSPICUOUS LEGENDS.

ARTICLE XII

MISCELLANEOUS PROVISIONS

        12.1    Expenses.    Each of DEFS and BUYER will bear its own costs and expenses (including legal fees and expenses) incurred in connection with the negotiation of this Agreement and the transactions contemplated hereby.

        12.2    Further Assurances.    From time to time, and without further consideration, each Party will execute and deliver to the other Party such documents and take such actions as the other Party may reasonably request in order to more effectively implement and carry into effect the transactions contemplated by this Agreement.

        12.3    Apportionment of Property Taxes; Transfer Taxes; and Recording Fees.      

        (a)   Prior to the Closing, DEFS shall determine, in accordance with this Section 12.3, the portion of general property Tax attributable to the period from January 1 (of the year in which Closing occurs) to the Effective Time (the "DEFS Property Tax"). DEFS shall pay the amount of the DEFS Property Tax to BUYER at Closing pursuant to the adjustment provisions of Section 3.2. The DEFS Property Tax shall be an amount equal to the product of (i) the amount of such general property Tax for the entire taxable period that includes the Effective Time (or, with respect to any property Tax, the amount of such general property Tax for the immediately preceding taxable period in the case of those Assets, if any, for which such general property Tax for the current period cannot be determined), times (ii) a fraction, the numerator of which is the number of days from January 1 (of the year in which Closing occurs) to the Effective Time and the denominator

35

of which is the total number of days in the entire taxable period. Notwithstanding anything in this Agreement to the contrary, no further adjustment shall be made for such general property Tax, BUYER hereby agreeing to assume the payment of all such general property Tax effective upon the Closing.

        (b)   DEFS and BUYER believe that this purchase and sale of the Assets is exempt from or is otherwise not subject to any and all sales, use, transfer, or similar Taxes. If any such sales, transfer, use or similar Taxes are due or should hereafter become due (including penalty and interest thereon) by reason of this transaction, DEFS shall timely pay and solely bear all such type of Taxes.

        (c)   BUYER shall record all assignments and of the conveyances of Real Property Interests with the appropriate Governmental Authorities. BUYER shall pay all documentary, filing, and recording fees incurred in connection with the filing and recording of the instruments of conveyance. As soon as practicable after Closing, BUYER shall provide DEFS with recorded copies of all documents conveying the Assets to BUYER.

        12.4    Assignment.    Except as specifically permitted by Section 7.15, neither Party may assign this Agreement or any of its rights or obligations arising hereunder without the prior written consent of the other Party; provided, however, that after written notice to DEFS, BUYER may assign its rights and obligations under this Agreement to an Affiliate without the consent of DEFS, but no such assignment shall release BUYER of its liability hereunder.

        12.5    Entire Agreement, Amendments and Waiver.    This Agreement, together with the Transaction Documents, the Confidentiality Agreement and all certificates, documents, instruments and writings that are delivered pursuant hereto and thereto contain the entire understanding of the Parties with respect to the transactions contemplated hereby and supersede all prior agreements, arrangements and understandings relating to the subject matter hereof; provided that the Confidentiality Agreement shall terminate upon Closing. This Agreement may be amended, superseded or canceled only by a written instrument duly executed by the Parties specifically stating that it amends, supersedes or cancels this Agreement. Any of the terms of this Agreement and any condition to a Party's obligations hereunder may be waived only in writing by that Party specifically stating that it waives a term or condition hereof. No waiver by either Party of any one or more conditions or defaults by the other in performance of any of the provisions of this Agreement shall operate or be construed as a waiver of any future conditions or defaults, whether of a like or different character, nor shall the waiver constitute a continuing waiver unless otherwise expressly provided.

        12.6    Severability.    Each portion of this Agreement is intended to be severable. If any term or provision hereof is illegal or invalid for any reason whatsoever, such illegality or invalidity shall not affect the validity of the remainder of this Agreement.

        12.7    Counterparts.    This Agreement may be executed simultaneously in any number of counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

        12.8    Governing Law, Dispute Resolution and Arbitration.      

        (a)    Governing Law.    This Agreement shall be governed by, enforced in accordance with, and interpreted under, the Laws of the State of Texas, without reference to conflicts of Laws principles.

        (b)    Negotiation.    In the event of any Arbitrable Dispute, the Parties shall promptly seek to resolve any such Arbitrable Dispute by negotiations between senior executives of the Parties who have authority to settle the Arbitrable Dispute. When a Party believes there is an Arbitrable Dispute under this Agreement, that Party will give the other Party prompt written notice of the Arbitrable Dispute. Within thirty (30) days after receipt of such notice, the receiving Party shall

36

submit to the other a written response. Both the notice and response shall include (i) a statement of each Party's position and a summary of the evidence and arguments supporting such position, and (ii) the name, title, fax number, and telephone number of the executive or executives who will represent that Party. In the event the Arbitrable Dispute involves a claim arising out of the actions of any Person not a signatory to this Agreement, the receiving Party shall have such additional time as necessary, not to exceed an additional thirty (30) days, to investigate the Arbitrable Dispute before submitting a written response. The executives shall meet at a mutually acceptable time and place within fifteen (15) days after the date of the response and thereafter as often as they reasonably deem necessary to exchange relevant information and to attempt to resolve the Arbitrable Dispute. If one of the executives intends to be accompanied at a meeting by an attorney, the other executive shall be given at least five (5) Business Days' notice of such intention and may also be accompanied by an attorney.

        (c)    Failure to Resolve.    If the Arbitrable Dispute has not been resolved within sixty (60) days after the date of the response given pursuant to Section 12.8(b) above, or such additional time, if any, that the Parties mutually agree to in writing, or if the Party receiving such notice denies the applicability of the provisions of Section 12.8(b) or otherwise refuses to participate under the provisions of Section 12.8(b), either Party may initiate binding arbitration pursuant to the provisions of Section 12.8(d) below.

        (d)    Arbitration.    Any Arbitrable Disputes not settled pursuant to the foregoing provisions shall be resolved through the use of binding arbitration in accordance with the Commercial Arbitration Rules of the American Arbitration Association ("Arbitration Rules"), as supplemented to the extent necessary to determine any procedural appeal questions by the Federal Arbitration Act (Title 9 of the United States Code) and in accordance with the following provisions:

        (i)    If there is any inconsistency between this Section 12.8(d) and the Arbitration Rules or the Federal Arbitration Act, the terms of this Section 12.8(d) will control the rights and obligations of the Parties.

        (ii)   Arbitration shall be initiated by a Party serving written notice, via certified mail, on the other Party that the first Party elects to refer the Arbitrable Dispute to binding arbitration, along with the name of the arbitrator appointed by the Party demanding arbitration and a statement of the matter in controversy. Within fifteen (15) days after receipt of such demand for arbitration, the receiving Party shall name its arbitrator. If the receiving Party fails or refuses to name its arbitrator within such fifteen (15) day period, the second arbitrator shall be appointed, upon request of the Party demanding arbitration, by the Chief U.S. District Court Judge for the District of Texas, or such other person designated by such judge. The two arbitrators so selected shall within fifteen (15) days after their designation select a third arbitrator; provided, however, that if the two arbitrators are not able to agree on a third arbitrator within such fifteen (15) day period, either Party may request the Chief U.S. District Court Judge for the District of Texas, or such other person designated by such judge to select the third arbitrator as soon as possible. In the event the Judge declines to appoint an arbitrator, appointment shall be made, upon application of either Party, pursuant to the Commercial Arbitration Rules of the American Arbitration Association. If any arbitrator refuses or fails to fulfill his or her duties hereunder, such arbitrator shall be replaced by the Party which selected such arbitrator (or if such arbitrator was selected by another Person, through the procedure which such arbitrator was selected) pursuant to the foregoing provisions.

        (iii)  The hearing will be conducted in Houston, Texas, no later than sixty (60) days following the selection of the arbitrators or thirty (30) days after all prehearing discovery has been completed, whichever is later, at which the Parties shall present such evidence and

37

witnesses as they may choose, with or without counsel. The Parties and the arbitrators should proceed diligently and in good faith in order that the award may be made as promptly as possible.

        (iv)  Except as provided in the Federal Arbitration Act, the decision of the arbitrators will be binding on and non-appealable by the Parties. Any such decision may be filed in any court of competent jurisdiction and may be enforced by any Party as a final judgment in such court.

        (v)   The arbitrators shall have no right or authority to grant or award damages that are precluded by Section 11.8.

        (vi)  The Federal Rules of Civil Procedure, as modified or supplemented by the local rules of civil procedure for the U.S. District Court of Texas, shall apply in the arbitration. The Parties shall make their witnesses available in a timely manner for discovery pursuant to such rules. If a Party fails to comply with this discovery agreement within the time established by the arbitrators, after resolving any discovery disputes, the arbitrators may take such failure to comply into consideration in reaching their decision. All discovery disputes shall be resolved by the arbitrators pursuant to the procedures set forth in the Federal Rules of Civil Procedure.

        (vii) Adherence to formal rules of evidence shall not be required. The arbitrators shall consider any evidence and testimony that they determine to be relevant.

        (viii) The Parties hereby request that the arbitrators render their decision within thirty (30) days following conclusion of the hearing.

        (ix)  The defenses of statute of limitations and laches shall be tolled from and after the date a Party gives the other Party written notice of an Arbitrable Dispute as provided in Section 12.8(b) above until such time as the Arbitrable Dispute has been resolved pursuant to Section 12.8(b), or an arbitration award has been entered pursuant to this Section 12.8(b).

        (e)    Recovery of Costs and Attorneys' Fees.    In the event arbitration arising out of this Agreement is initiated by either Party, after the entry of a final non-appealable order, if one Party has predominantly prevailed in the dispute, it shall be entitled to recover from the other Party all court costs, fees and expenses of such arbitration, including reasonable attorneys' fees that are specifically included in the arbitration award.

        (f)    Choice of Forum.    If, despite the Parties' agreement to submit any Arbitrable Disputes to binding arbitration, there are any court proceedings arising out of or relating to this Agreement or the transactions contemplated hereby, such proceedings shall be brought and tried in, and the Parties hereby consent to the jurisdiction of, the federal or state courts situated in Houston, Texas.

        (g)    Jury Waivers.    THE PARTIES HEREBY WAIVE ANY AND ALL RIGHTS TO DEMAND A TRIAL BY JURY.

        (h)    Settlement Proceedings.    All aspects of any settlement proceedings, including discovery, testimony and other evidence, negotiations and communications pursuant to this Section 12.8, briefs and the award shall be held confidential by each Party and the arbitrators, and shall be treated as compromise and settlement negotiations for the purposes of the Federal and State Rules of Evidence.

        12.9    Notices and Addresses.    Any notice, request, instruction, waiver or other communication to be given hereunder by either Party shall be in writing and shall be considered duly delivered if personally delivered, mailed by certified mail with the postage prepaid (return receipt requested), sent

        12.14    Non-Compete; Confidentiality.      

        (a)   For a period of two years following the Closing Date, DEFS agrees, for itself and for its Affiliates, and their respective successors or assigns (collectively, the "DEFS Companies") that the DEFS Companies will not, directly or indirectly, compete with BUYER or its Affiliates by (i) acquiring transportation capacity on the AIM System, (ii) selling natural gas to any facility served, previously served by or connected to the AIM System at the Effective Time, or (iii) purchasing natural gas produced from any production facilities connected to the AIM System at the Effective Time. DEFS, for itself and each of the DEFS Companies, acknowledges that the restrictions contained in this Section 12.14 are reasonable and necessary to protect the legitimate interests of BUYER and its Affiliates, and that BUYER would not have entered into this Agreement in the absence of such restrictions. DEFS, for itself and each of the DEFS Companies, also acknowledges that any breach of Section 12.14 will cause continuing and irreparable injury to BUYER for which monetary damages would not be an adequate remedy. In the event of such breach by any of the DEFS Companies, BUYER shall have the right to enforce the provisions of this Section 12.14 by seeking injunctive or other equitable relief in any court, and this Agreement shall not in any way limit remedies of equity available to BUYER. In the event that the provisions of this Section 12.14 should ever be adjudicated to exceed the time, geographic, or other limitations permitted by applicable Law in any applicable jurisdiction, then such provisions shall be deemed reformed in such jurisdiction to the maximum time, geographic, or other limitations permitted by applicable Law. Notwithstanding the foregoing, the restrictions contained in this Section 12.14(a) shall not apply (i) following the acquisition of DEFS or substantially all of its assets by a Third Person, or the merger or consolidation of DEFS with a Third Person other than the Persons owning DEFS as of the date hereof, or (ii) if DEFS acquires directly or indirectly assets capable of being served by the AIM System or which include capacity on the AIM System as part of a transaction having a total value in excess of $200,000,000.

        (b)   Effective at Closing, the Confidentiality Agreement is terminated, and DEFS will assign to BUYER the benefit of and the right to enforce any other confidentiality agreement entered into by DEFS or any of its Affiliates related to the sale or any attempt to sell the Assets. From and after Closing, DEFS will not, except as required by applicable Law, disclose any "Proprietary Information" as defined in the Confidentiality Agreement to any other Person or otherwise use any such Proprietary Information to the competitive disadvantage of BUYER.

        (c)   Without the prior written consent of the other Party, neither Party shall publicly disclose the terms of the transactions contemplated herein, this Agreement or the Exhibits or Schedules hereto unless in the opinion of counsel to the disclosing Party, such disclosure is required by law, or such disclosure is requested by any Governmental Authority, in which event, the disclosing Party shall give the other Party as much prior written notice as practicable under the circumstances and

will cooperate with such other Party in obtaining confidential treatment of such information as such other Party may reasonably request.
