REORGANIZATION AGREEMENT (this “Agreement”), dated as of May 26, 2005, by and among CONOCOPHILLIPS, a Delaware corporation (“COP”), DUKE CAPITAL LLC, a Delaware limited liability company (“Duke”), and DUKE ENERGY FIELD SERVICES, LLC, a Delaware limited liability company (“Company”).

RECITALS

Company indirectly owned all of the Equity Interests (as such term is defined below) in Texas Eastern Products Pipelines Company, LLC, a Delaware limited liability company (“TEPPCO GP”), which serves as the general partner of TEPPCO Partners, LP, a Delaware master limited partnership (“TEPPCO”). Company and Enterprise GP Holdings L.P. (“GP Purchaser”) are parties to a Purchase and Sale Agreement dated February 24, 2005 (the “TEPPCO Agreement”) pursuant to which Company sold to GP Purchaser all of the Equity Interests in TEPPCO GP (the “TEPPCO GP Sale” and “TEPPCO GP Equity Interests”, respectively) and TEPPCO Holdings, Inc., an indirectly wholly-owned subsidiary of Duke, sold certain limited partner units in TEPPCO.

In connection with the TEPPCO GP Sale, Company made a bona fide loan to Duke (the “Duke Note”) in an amount of $766,700,000, equal to 69.70% of the proceeds from the TEPPCO GP Sale, and a bona fide loan to COP (the “COP Note”) in an amount of $333,300,000, equal to 30.3% of the proceeds from the TEPPCO GP Sale.

COP desires to increase its indirect ownership interest in Company to a 50% Percentage Interest (as such term is defined below). This increase in COP’s indirect ownership interest in Company, and the corresponding dilution in Duke’s indirect ownership interest in Company, is to be accomplished through the transfers, distributions and contribution and the amendment and restatement of the Amended and Restated LLC Agreement (as defined herein) described below.

Duke, indirectly through DEFS Holding (as such term is defined below), owns an Equity Interest (as such term is defined below) in Company which has a 69.70% Percentage Interest. Duke, through DEFS Holding, is willing to transfer to COP Transferee (as such term is defined below) a portion of such Equity Interest equal to an approximate 6.47% Percentage Interest in accordance with and subject to the terms and conditions set forth in this Agreement.

All of the proceeds received by Company from the sale of the TEPPCO GP Equity Interests are to be distributed 100% to DEFS Holding in accordance with and subject to the terms and conditions set forth in this Agreement.

Company, through various subsidiaries, owns all of the Equity Interests in Canadian Holding Company and is willing to distribute those Equity Interests to DEFS Holding in accordance with and subject to the terms and conditions set forth in this Agreement.

COP, through one or more subsidiaries, owns the Empress System Business (as such term is defined below) and is willing to transfer the Empress System Business to Duke Transferee (as such term is defined below) in accordance with and subject to the terms and conditions set forth in this Agreement.

NOW, THEREFORE, in consideration of the premises and the representations, warranties, covenants and agreements contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound hereby, the parties hereto hereby agree as follows:

With respect to events occurring prior to the Applicable Closing Date, each Applicable Transferee shall be entitled to the benefits of insurance from independent sources (not affiliated with the Applicable Transferor) maintained by or for the benefit of the Empress System Business or the Canadian Assets Business, as applicable, with respect to properties and assets of the Empress System Business or the Canadian Assets Business, as applicable; provided, however, that notwithstanding anything to the contrary contained in this Agreement, from and after the Applicable Closing Date, except as otherwise agreed by the Applicable Transferor and the Applicable Transferee, none of Canadian Holding Company, the Canadian Assets Subsidiaries, PTC or Duke Transferee shall be entitled to any insurance recovery from any Applicable Transferor-affiliated insurance company. Further, the Applicable Transferee shall indemnify and hold harmless the Applicable Transferor from any retroactive premiums imposed by any insurer under programs or policies maintained by the Applicable Transferor prior to the Applicable Closing as a result of any claims made after the Applicable Closing Date with respect to the properties and assets of the Empress System Business or the Canadian Assets Business, as applicable, regardless of the date of loss.

Section 7.12 Guaranties. In the event that after the Applicable Closing Date COP or any Affiliate thereof (other than Company or its Subsidiaries) or Company or any Affiliate thereof (other than Canadian Holding Company and the Canadian Assets Subsidiaries) remains liable under or for any of the guarantees (whether of payment or performance), letters of credit or other undertakings it has delivered prior to the Applicable Closing Date to others for the benefit of the Empress System Business or the Canadian Assets Business, as applicable and that are described on Schedule 7.12 of the COP Disclosure Schedule or Schedule 7.12 of the Company Disclosure Schedule, as applicable (collectively, the “Undertakings”), the Applicable Transferee agrees to indemnify and hold harmless the Applicable Transferor or such Affiliate thereof from any cost, expense or loss (including reasonable attorneys’ fees) incurred by the Applicable Transferor or such Affiliate thereof arising directly or indirectly therefrom with respect to post-Applicable Closing periods except insofar as such cost, expense or loss constitutes or arises from a matter with respect to which the Applicable Transferee is entitled to indemnification hereunder. Any reasonable out-of-pocket expense incurred by the Applicable Transferor with respect to maintaining such support for periods after the Applicable Closing Date shall be reimbursed to the Applicable Transferor by the Applicable Transferee. Each Applicable Transferee shall use its reasonable efforts (including an offer of a substitute guarantee, letter of credit or undertaking) to cause or procure the release, within six months of the Applicable Closing Date, of all liabilities or obligations of each Applicable Transferor or any Affiliate thereof (other than the Applicable Transferee or its Subsidiaries) with respect to the Undertakings designated as “Release Undertakings” on Schedule 7.12 of the COP Disclosure Schedule or Schedule 7.12 of the Company Disclosure Schedule, as applicable, from any of the liabilities or obligations of the Empress System Business or the Canadian Assets Business, as applicable, for post-Closing periods.

Section 7.13 Actions by Affiliates of the Parties. Each Party shall ensure that each of their respective Affiliates takes all actions necessary to be taken by such Affiliate in order to fulfill the obligations of such Party, as the case may be, under this Agreement.

Section 7.14 Radio Licences; Radio Towers. (a) Prior to the Applicable Closing Date, or as soon thereafter as practicable, COP shall use commercially reasonable efforts to assign, or cause to be assigned, to Duke Transferee all of the Radio Licences used solely by ES Transferor or PTC but held of record by COP or a COP Retained Affiliate as of the date hereof, including those identified on Schedule 7.14(a) of the COP Disclosure Schedule. COP shall cause each such assignment to be filed with Industry Canada, shall use commercially reasonable efforts to obtain any approvals and consents from Industry Canada necessary for such transfer and shall pay all fees and other costs incurred in connection therewith.

(b) This clause (b) applies to any Radio Licence identified in Schedule 7.14(a) of the COP Disclosure Schedule that is currently being used simultaneously by COP or a COP Retained Affiliate and by ES Transferor or PTC in their respective business operations (“Shared License”). Prior to the Applicable Closing, COP shall use commercially reasonable efforts to obtain two Radio Licences in replacement of the Shared License, one in the name of and for the benefit of COP or such COP Retained Affiliate and the second in the name of and for the benefit of Duke Transferee or PTC, as applicable. COP shall pay, or cause the applicable COP Retained Affiliate to pay, all fees and other costs incurred in connection therewith. In the event that COP is unable to obtain two replacement licenses, COP will transfer the Shared License to Duke Transferee or PTC, as applicable, subject to a mutually acceptable arrangement whereby COP or such COP Retained Affiliate, as the case may be, shall be permitted to continue to use such Radio Licence subsequent to the Applicable Closing for substantially the same purpose, in substantially the same manner and to substantially the same extent as prior to the Applicable Closing. Any such shared-use arrangement with respect to the Shared License shall be finalized not later than the date on which the Shared License is transferred. COP shall pay, or shall cause the applicable COP Retained Affiliate to pay, all fees and other costs incurred in connection therewith.

(c) If COP or a COP Retained Affiliate, as of the date of this Agreement, owns the radio tower corresponding to any Radio Licence identified in Schedule 7.14(a) of the COP Disclosure Schedule, then COP and the Applicable Transferee, both acting reasonably and in good faith, shall jointly prepare and agree upon a mutually acceptable arrangement whereby COP or such COP Retained Affiliate, as the case may be, shall be permitted to continue to use such radio tower subsequent to the Applicable Closing for substantially the same purpose, in substantially the same manner and to substantially the same extent as prior to the Applicable Closing. COP shall use commercially reasonable efforts to obtain, prior to Applicable Closing, consent of third-party tower lessors for the assignment to Duke Transferee or PTC, as applicable, of all tower leases corresponding to the Radio Licences required to be transferred herein. In those instances where the third-party lessor does not consent to such transfer, COP and the Applicable Transferee shall prepare and agree upon a shared-use agreement with respect to the radio tower as described below. Any such shared-use arrangement with respect to a radio tower (i) shall be finalized not later than the date on which title to such radio tower is conveyed of record to Duke Transferee or PTC, as applicable, (ii) shall be structured so as to minimize the interference of any use of such radio tower by either party to such arrangement with any use of such radio tower by the other party, and (iii) shall provide for reasonable rights of ingress and

egress to and from such radio tower where necessary. It is anticipated that any such shared-use arrangements with respect to radio towers will in most cases consist of (A) the transfer by COP or the COP Retained Affiliate to Duke Transferee or PTC as applicable, of record legal title to such radio tower and the fee property on which such tower is located and (B) the grant by Duke Transferee or PTC, as applicable, of a perpetual easement or license to COP or a COP Retained Affiliate. COP shall cause a general warranty deed for each such transfer to be prepared, executed and filed of record in the appropriate land title recording office, and shall pay all recording fees, deed stamp taxes and other costs incurred in connection with such recordation.

(d) Prior to the Applicable Closing Date, or as soon thereafter as practicable, Company shall use commercially reasonable efforts to cause to be assigned to Canadian Holding Company or the Canadian Assets Subsidiaries, as appropriate, all of the Radio Licences used solely by them but held of record by third parties as of the date hereof, including those identified on Schedule 7.14(d) of the Company Disclosure Schedule. Company shall use its commercially reasonable efforts to (i) cause each such assignment to be filed with Industry Canada and (ii) obtain any approvals and consents from Industry Canada, as the case may be, necessary for such transfer, and Company shall pay all fees and other costs incurred in connection with such assignment (other than such fees and costs paid by such third parties).

Section 7.15 Post-Closing TEPPCO Adjustment. (a) If subsequent to the Second Closing Date Company receives proceeds from a purchase price or similar adjustment pursuant to the TEPPCO Agreement or otherwise relating to the TEPPCO Sale, Company shall make a cash distribution to each of DEFS Holding and CPGC in the following amount: (i) to DEFS Holding, an amount equal to such proceeds multiplied by 0.697, and (ii) to CPGC, an amount equal to such proceeds multiplied by 0.303. Any such aforesaid distributions shall be made by wire transfer of immediately available funds to an account designated by each of DEFS Holding and CPGC, as applicable.

(b) If subsequent to the Second Closing Date Company shall be required to pay a purchase price or similar adjustment pursuant to the TEPPCO Agreement or otherwise relating to the TEPPCO Sale, each of DEFS Holding and CPGC shall make a cash contribution to Company in the following amount: (i) from DEFS Holding, an amount equal to such payment multiplied by 0.697, and (ii) from CPGC, an amount equal to such payment multiplied by 0.303. Any such aforesaid contributions shall be made by wire transfer of immediately available funds to an account designated by Company.

(c) Any Profits or Losses (as defined in the Second Amended and Restated LLC Agreement) arising solely from a receipt or payment described in Section 7.15(a) or (b) shall be allocated 69.7% to DEFS Holding and 30.3% to CPGC.

Section 7.16 Empress System Business Covenants. (a) If on the Empress Target Closing Date, (i) one or more Business Representations and Warranties of COP, to the extent made in respect of the Empress System Business, shall not be true and correct both when made and on and as of such Empress Target Closing Date with the same effect as though such representations and warranties had been made on and as of such Empress Target Closing Date (except for representations and warranties expressly made as of an earlier date, in which case as of such date), except for such failures to be true and correct (without giving effect to any

Materiality Requirement) which, individually or in the aggregate, do not have a Material Adverse Effect on the Empress System Business, (ii) one or more covenants and agreements of COP to be performed and complied with on or before such Empress Target Closing Date in accordance with this Agreement with respect to the Empress System Business shall not have been duly performed and complied with in all material respects, (iii) Duke shall not have received a certificate dated the Empress Target Closing Date and validly executed on behalf of COP by an officer of COP to the effect that the contingencies described in clauses (i) and (ii) of this Section 7.16(a) have not occurred, or (iv) from December 31, 2004 through the Empress Target Closing Date, a Material Adverse Effect on the Empress System Business shall have occurred, or there shall exist one or more facts or circumstances which would reasonably be expected to have a Material Adverse Effect on the Empress System Business (each of the contingencies set forth in clauses (i), (ii), (iii) and (iv) above, an “Empress Contingency”), then on the Empress Target Closing Date, the Empress System Business shall not be transferred to Duke and Duke Transferee shall not pay the Empress System Amount to ES Transferor unless Duke determines that such transfer and payment should occur in its sole discretion.

(b) Notwithstanding anything to the contrary in Article II, Article III or Article VIII, if on the Empress Target Closing Date, one or more Required Governmental Consents or Required Empress Consents shall not have been obtained with respect to the Empress System Business, and otherwise all conditions set forth in Article VIII shall have been satisfied or waived, then the Empress System Business shall not be transferred to Duke Transferee on the Empress Target Closing Date and Duke Transferee shall not pay the Empress System Amount to ES Transferor. Should the Empress System Business not be transferred to Duke Transferee in the circumstances described in the preceding sentence, Duke and COP agree to use reasonable best efforts to obtain the Required Empress Consent(s) and complete the applicable review process with each Governmental Entity that has not granted one or more such Required Governmental Consents. If all Empress Contingencies (if any) that existed on the Empress Target Closing Date shall have been cured within 30 days after the Empress Target Closing Date, and all such Required Empress Consents and Required Governmental Consents are obtained prior to or on the date that is eighteen months after the Empress Target Closing Date, then the Empress System Business shall be transferred to Duke Transferee and Duke Transferee shall pay the Empress System Amount to ES Transferor on the same date which date (such date, the “Replacement Empress Closing Date”) shall be the first Business Day of the calendar month next following the later of (A) the date the last such Required Governmental Consent and Required Empress Consent is obtained and (B) the date all such Empress Contingencies are cured; provided that such transactions shall only take place if no Empress Contingency is existing and all of the conditions set forth in Sections 8.1 (other than with respect to Company) and 8.2 (other than with respect to Company) have been satisfied or waived, in each case mutatis mutandis with the term “Replacement Empress Closing Date” replacing the terms “First Closing Date” and “Empress Target Closing Date” in such clauses and Sections and in clauses (i) through (iv) of Section 7.16(a).

Section 7.17 Company Conduct. From the date hereof until the Second Closing (including, for the avoidance of doubt, during the period between the First Closing and the Second Closing), Company will continue to manage its business in the ordinary course consistent with past practice to generate cash flows from operations and to maintain normal levels of working capital. In furtherance of the foregoing, from the date hereof until the Second

Closing, in a manner consistent with past practice, the Company will (and Duke and COP will cause the Company to) make quarterly distributions within 30 days of the end of each fiscal quarter of Company in an amount equal to the lesser of 90% of the net income of Company for such fiscal quarter and 75% of the net cash flow of Company for such fiscal quarter to the Members (as defined in the Amended and Restated LLC Agreement) in the proportion set forth in the Amended and Restated LLC Agreement.

Section 7.18 Preparation of Financials. (a) COP shall use reasonable best efforts at Duke’s request and expense to assist Duke, promptly following request from time to time, in the preparation of consolidated audited financial statements for the Empress System Business for the most recent three fiscal years ending prior to the Applicable Closing Date and the fiscal year during which the Applicable Closing Date occurs, including providing reasonable access to (i) COP’s employees, (ii) appropriate members of COP’s management (including senior management, if appropriate), (iii) COP’s auditors and other third parties with information relevant to the preparation of such financial statements, to answer Duke’s questions concerning the business operations and affairs of the Empress System Business, and (iv) corporate records, books of accounts, contracts, financial statements, tax records, and all other documents reasonably requested by Duke.

(b) Company shall use reasonable best efforts at Duke’s request and expense to assist Duke, promptly following request from time to time, in the preparation of consolidated audited financial statements for the Canadian Assets Subsidiaries for the most recent three fiscal years ending prior to the First Closing Date and the fiscal year during which the First Closing Date occurs, including providing reasonable access to (i) Company’s employees, (ii) appropriate members of Company’s management (including senior management, if appropriate), (iii) Company’s auditor’s and other third parties with information relevant to the preparation of such financial statements, to answer Duke’s questions concerning the business operations and affairs of the Canadian Assets Subsidiaries, and (iv) corporate records, books of accounts, contracts, financial statements, tax records, and all other documents reasonably requested by Duke.

Section 7.19 Additional Covenant of Duke. Duke agrees not to dividend or distribute on its equity any assets unless immediately thereafter at least one of the following existed: (a) Duke would have an investment grade credit rating, (b) Duke would be able to comply from a financial standpoint with its reasonably expected future obligations under this Agreement, or (c) Duke would have its reasonably expected future obligations under this Agreement guaranteed by an entity that either has an investment grade credit rating or is able to comply from a financial standpoint with such reasonably expected future obligations.

(c) Matters relating to indemnification for Taxes shall not be governed by this Article X (other than this Section 10.2(c)), except to the extent otherwise provided in Article XII.

Section 10.3 Indemnification Procedure. All claims by any Indemnified Party under Article VII or this Article X shall be asserted and resolved as follows:

(a) In the event that (i) any claim, demand or proceeding is asserted or instituted in writing by any Person other than the parties to this Agreement or their Affiliates which could give rise to Damages for which an Indemnifying Party could be liable to an Indemnified Party under this Agreement (such claim, demand or proceeding, a “Third-Party Claim”) or (ii) any Indemnified Party shall have a claim to be indemnified by any Indemnifying Party under this Agreement which does not involve a Third-Party Claim (such claim, a “Direct Claim”), the Indemnified Party shall promptly send to the Indemnifying Party a written notice specifying the nature of such claim, together with information reasonably available to the Indemnified Party with respect to such claim (a “Claim Notice”), provided that, subject to the last sentence of Section 10.4, a delay in notifying the Indemnifying Party shall not relieve the Indemnifying Party of its obligations under this Agreement except to the extent that such failure shall have caused actual prejudice to the Indemnifying Party. In the case where Company is the Indemnified Party, either Duke or COP may assert an indemnity claim on behalf of Company and each shall be considered an Indemnified Party for purposes of this Section 10.3 in connection with any Third-Party Claim or Direct Claim for which the other is the Indemnifying Party.

(b) In the event of a Third-Party Claim, the Indemnifying Party shall have 30 days (or 10 days with respect to a Claim Notice relating to the Empress System Business or the Canadian Assets Subsidiaries) after receipt of the Claim Notice relating to such Third-Party Claim to elect to undertake, conduct and control, through counsel of its own choosing (provided that such counsel is reasonably acceptable to the Indemnified Party) and at its own expense, the settlement or defense of such Third-Party Claim (in which case the Indemnifying Party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by any Indemnified Party except as set forth below). If the Indemnifying Party elects to undertake such defense, it shall promptly assume and hold such Indemnified Party harmless from and against the full amount of any Damages resulting from such Third-Party Claim to the extent provided herein. Notwithstanding an Indemnifying Party’s election to undertake, conduct and control such Third-Party Claim, the Indemnified Party shall have the right to employ separate counsel, and the Indemnifying Party shall bear the reasonable fees, costs and expenses of such separate counsel, if the use of the counsel selected by the Indemnifying Party to represent the Indemnified Party would present such counsel with a conflict of interest. If the Indemnifying Party elects to undertake such defense, (i) the Indemnified Party agrees to cooperate with the Indemnifying

Party and its counsel in contesting such Third-Party Claim, and, if appropriate and related to such Third-Party Claim, the parties will reasonably cooperate with each other in connection with making any counterclaim against the person asserting the Third-Party Claim, or any cross-complaint against any Person, (ii) such Third-Party Claim may not be settled or compromised by the Indemnified Party without the prior written consent of the Indemnifying Party; provided that in the event any Indemnified Party settles or compromises or consents to the entry of any judgment with respect to any Third-Party Claim without the prior written consent of the Indemnifying Party, such Indemnified Party shall be deemed to have waived all rights against the Indemnifying Party for indemnification under this Article X, and (iii) the Indemnifying Party shall not, except with the consent of the Indemnified Party, enter into any settlement that does not include as an unconditional term thereof the giving by the third-party asserting such claim to all Indemnified Parties of (A) unconditional release from all liability with respect to such Third-Party Claim or (B) consent to entry of any judgment. If the Indemnifying Party does not notify the Indemnified Party of its election to undertake the defense of such Third-Party Claim within 30 days after receipt of the Claim Notice relating to such Third-Party Claim (or 10 days with respect to a Claim Notice relating to the Empress System Business or the Canadian Assets Subsidiaries), the Indemnified Party shall have the right to contest, settle, compromise or consent to the entry of any judgment with respect to such Third-Party Claim and in doing so shall not thereby waive any right to indemnity therefor pursuant to this Article X, provided that at any time thereafter the Indemnifying Party may assume the defense of such Third-Party Claim.

(c) In the event of a Direct Claim, the Indemnifying Party shall notify the Indemnified Party within 30 days (or 10 days with respect to Empress System Business and Canadian Assets Subsidiaries) of receipt of a Claim Notice whether or not the Indemnifying Party disputes such claim.

(d) From and after the delivery of a Claim Notice under this Agreement, at the reasonable request of the Indemnifying Party the Indemnified Party shall grant the Indemnifying Party and its representatives all reasonable access to the books, records and properties of such Indemnified Party to the extent reasonably related to the matters to which the Claim Notice relates. All such access shall be granted during normal business hours and shall be granted under conditions which will not unreasonably interfere with the business and operations of such Indemnified Party. The Indemnifying Party will not, and shall cause its representatives not to, use (except in connection with such Claim Notice) or disclose to any third Person other than the Indemnifying Party’s representatives (except as may be required by applicable law) any information obtained pursuant to this Section 10.3, which is designated as confidential by the Indemnified Party.

Section 10.4 Survival. The representations and warranties of the parties contained in this Agreement shall survive each Closing and remain enforceable for 18 months from the Applicable Closing Date; provided that (i) the representations and warranties set forth in Section 4.11 (Environmental) shall survive each Closing and remain enforceable for 36 months from the Applicable Closing Date, (ii) the representations and warranties set forth in Sections 4.1, 4.2, 4.3, 4.6, 5.1, 5.2, 5.3, 5.4, 6.1, 6.2, 6.3 and 6.4 shall survive each Closing and remain enforceable without time limit and (iii) the representations and warranties set forth in Article XII shall survive to the extent provided in Article XII. No claim for indemnity under this Article X for any breach of a representation or warranty may be brought unless the appropriate

Claim Notice shall have been delivered to the Indemnifying Party prior to expiration of the applicable survival period. Notwithstanding the foregoing, any covenants or agreements contained in this Agreement (including any covenants or agreements contained in any representation or warranty) shall survive each Closing and remain enforceable without time limit.

Section 10.5 Indemnification Limitation. (a) Each Indemnified Party under this Article X shall use its reasonable efforts to mitigate Damages for which it seeks indemnification hereunder and shall assign to the Indemnifying Party all of such Indemnified Party’s claims for recovery against third parties as to Damages, whether by insurance coverage, contribution claims, subrogation or otherwise.

(b) Except as otherwise provided herein, Company’s obligation to indemnify the other Parties and their respective Affiliates as provided in Section 10.1 shall not become effective until the aggregate of all Damages sustained by the other Parties and their respective Affiliates as described in Section 10.1 shall have exceeded the Applicable Basket. If the aggregate amount of Damages sustained by the other Parties and their respective Affiliates as described in Section 10.1 exceeds the Applicable Basket then the other Parties and their Affiliates shall be entitled to assert claims under this Article X for indemnification for the amount of such Damages in excess of the Applicable Basket only; provided that Company’s obligation under this Article X shall not exceed the Applicable Cap in the aggregate.

(c) Except as otherwise provided herein, COP’s obligation to indemnify the other Parties and their respective Affiliates as provided in Section 10.2 shall not become effective until the aggregate of all Damages sustained by the other Parties and their respective Affiliates as described in Section 10.2 shall have exceeded the Applicable Basket. If the aggregate amount of Damages sustained by the other Parties and their respective Affiliates as described in Section 10.2 exceeds the Applicable Basket then the other Parties and their Affiliates shall be entitled to assert claims under this Article X for indemnification for the amount of such Damages in excess of the Applicable Basket only; provided that COP’s obligation under this Article X shall not exceed the Applicable Cap in the aggregate.

(d) Except as otherwise provided herein, Duke’s obligation to indemnify the other Parties and their respective Affiliates as provided in Section 10.2 shall not become effective until the aggregate of all Damages sustained by the other Parties and their respective Affiliates as described in Section 10.2 shall have exceeded the Applicable Basket. If the aggregate amount of Damages sustained by the other Parties and their respective Affiliates as described in Section 10.2 exceeds the Applicable Basket then the other Parties and their Affiliates shall be entitled to assert claims under this Article X for indemnification for the amount of such Damages in excess of the Applicable Basket only; provided that Duke’s obligation under this Article X shall not exceed the Applicable Cap in the aggregate.

(e) Notwithstanding the foregoing, (i) the indemnification provision set forth in Section 10.1(b), Section 10.1(c), Section 10.2(a)(ii), Section 10.2(a)(iii), Section 10.2(a)(iv), Section 10.2(b)(ii), Section 10.2(b)(iii) and Section 10.2(b)(iv) shall not be subject to the Basket or Cap and (ii) none of Duke, COP or Company or their respective Affiliates shall be entitled to assert claims for indemnification under this Article X unless the aggregate amount of Damages

claimed in any individual Claim Notice exceeds (A) with respect to Claim Notices claiming indemnification solely under the Organizational Representations and Warranties, $260,000 and (B) with respect to all other Claim Notices, $50,000.

(f) The parties hereto agree that the indemnification provisions in Articles VII and X shall be the exclusive remedy of the parties with respect to breaches of the representations and warranties in Articles IV, V and VI, except for actions grounded in fraud, with respect to which the remedies and limitations set forth in this Agreement shall not apply or in any manner limit the scope or availability of any other remedy at law or in equity.

Section 10.6 Materiality Qualifiers. For purposes of determining Damages and rights to indemnification under this Article X, the representations and warranties set forth in Articles IV, V and VI shall be read without giving effect to any Materiality Requirement set forth therein; provided, that representations and warranties qualified by “Material Adverse Effect” shall be deemed to be true to the extent the breach thereof is reasonably attributable to the general state of the industries in which such Party and its Subsidiaries operate (including natural gas and petroleum price levels), to general economic conditions in the United States and Canada (including prevailing interest rate and stock market levels) or to the transactions contemplated by this Agreement. As used in this Agreement, a “Materiality Requirement” shall mean any requirement in a representation or warranty that a condition, event or state of fact be “material,” correct or true in “all material respects,” have a “Material Adverse Effect,” “COP Sale-Related Material Adverse Effect,” or “Canadian Assets Material Adverse Effect,” or be or not be “reasonably expected to have a Material Adverse Effect” (or Canadian Assets Material Adverse Effect or COP Sale-Related Material Adverse Effect) (or other words or phrases of similar effect or impact) in order for such condition, event or state of facts to cause such representation or warranty to be inaccurate.

ARTICLE XI

EMPLOYEE MATTERS

Section 11.1 Empress System Employees. (a) No later than 10 days prior to the Applicable Closing Date, but effective as of the Applicable Closing Date, Duke shall, or Duke shall cause an Affiliate of Duke to, make offers of employment to all non-unionized Empress System Employees who are employed by COP or a Subsidiary of COP immediately prior to the Applicable Closing Date (which offers shall be for full-time or part-time employment consistent with the employment status of the particular Empress System Employee with COP or a Subsidiary of COP). The terms and conditions of each such offer of employment shall be consistent with the provisions of this Section 11.1. In respect of the unionized Empress System Employees employed by COP or a Subsidiary of COP immediately prior to the Applicable Closing Date, Duke or an Affiliate of Duke will be the successor employer under the Collective Agreements between COP (or its applicable Subsidiary) and the Communications, Energy and Paperworkers Union, Locals 745 and 746 pursuant to the provisions of applicable labor legislation, and effective as of the Applicable Closing Date, Duke or an Affiliate of Duke shall accept all legal obligations and responsibilities arising under such legislation with respect to the Continuing Empress System Employees who are subject to such agreements. As used in this Agreement, the term “Continuing Empress System Employee” means each individual who accepts an offer of employment from Duke or an Affiliate of Duke or in respect of whom Duke

or an Affiliate of Duke becomes the successor employer as provided in the preceding provisions of this paragraph. The Hire Date for each non-unionized Empress System Employee who accepts an employment offer from Duke or an Affiliate of Duke pursuant to the first sentence of this paragraph and who actually becomes employed by Duke or an Affiliate of Duke in accordance with such offer shall be the Applicable Closing Date, except with respect to those individuals to whom employment offers are made and who are not Actively Employed as of the Applicable Closing Date, in which case the Hire Date shall be the date upon which such individual is able to and does commence active duty with Duke or an Affiliate of Duke, it being agreed that with respect to an Empress System Employee who is not Actively Employed as of the Applicable Closing Date due to disability but who subsequently obtains a medical release to return to work (which medical release, if requested by Duke, is confirmed by a doctor selected by Duke), Duke or its applicable Affiliate will participate with such employee in a return-to-work program, intended to lead to full-time employment for that employee with Duke or its applicable Affiliate. From the Applicable Closing Date through the first anniversary thereof, Duke and its Affiliates shall provide each Continuing Empress System Employee with compensation and employee benefits that are substantially similar in aggregate economic value to the compensation and employee benefits provided to such employee immediately prior to the Applicable Closing Date. Neither COP nor any of its Affiliates shall, unless acting in accordance with Duke’s prior written consent, (i) during the period beginning on the date of this Agreement and ending on the Applicable Closing Date, solicit, encourage or induce any Empress System Employee to reject an employment offer from Duke or an Affiliate of Duke or solicit, encourage or induce any such employee to continue in the employment of COP or any of its Affiliates from and after the Applicable Closing Date and (ii) for the period beginning on the Applicable Closing Date and ending on the date that is one year after the Applicable Closing Date, solicit, encourage or induce any Continuing Empress System Employee to become an employee of COP or any of its Affiliates; provided, however, that this sentence shall not (x) apply to any Continuing Empress System Employee whose employment has been terminated by Duke and its Affiliates, (y) prohibit COP or any of its Affiliates from making a general solicitation by advertisement or otherwise (and from thereafter soliciting or hiring any Continuing Empress System Employee who responds to such general solicitation), or (z) apply to the Empress System Employees designated on Schedule 11.1(a) as “Multiple Offer Employees”; provided, further, that (A) in no event shall COP or any of its Affiliates, during the period beginning on the date of this Agreement and ending on the date that is one year after the Applicable Closing Date, offer or provide a Multiple Offer Employee with compensation or benefits in excess of the compensation and benefits provided by COP and its Affiliates to such employee immediately prior to the date of this Agreement (other than for increases in compensation and benefits that are of general applicability to employees of COP, including any merit raises in salary resulting from the annual review processes of COP and its Affiliates, operated in the ordinary course) and (B) the exception to the application of this sentence that is provided for in clause (z) of this sentence shall cease to apply with respect to a particular Multiple Offer Employee immediately upon the acceptance by such employee of an employment offer from Duke or an Affiliate of Duke. With respect to each Empress System Employee (other than a Multiple Offer Employee) to whom Duke or an Affiliate of Duke makes an employment offer on or before the Applicable Closing Date in accordance with this Section 11.1(a), COP and its Affiliates shall not take any action to influence such employee to reject such offer, including assisting such employee in procuring alternative employment arrangements.

(b) Except to the extent specifically provided elsewhere in this Section 11.1, Duke Group shall not, and from and after the Applicable Closing Date, PTC shall not, have any responsibility or liability with respect to the COP Plans. Duke or an Affiliate of Duke shall, as of each Continuing Empress System Employee’s Hire Date, assume and honor all accrued vacation entitlement of such employee.

(c) On and after the applicable Hire Date, Duke shall cause each Continuing Empress System Employee to receive full credit for all service credited under the COP Plans for all purposes (including eligibility to participate, vesting and benefit accrual) under the corresponding employee benefit plans and policies of Duke and its Affiliates, including vacation, floating holidays, retirement, severance and pension plans; provided, however, that such service credit for benefit accrual purposes shall not be provided under any defined benefit plan, except that such service credit for benefit accrual purposes shall be recognized under the defined benefit component of the Duke Canadian Pension Plan subject to (i) the completion of the transfers described in Sections 11.1(d)(iii) and (iv) and (ii) limitation by Duke and its Affiliates to the extent necessary to ensure that benefits in excess of those accrued under the defined benefit component of the COP Canadian Pension Plan (assuming for this purpose, however, that the amount so accrued was based upon the final average pay that would have applied under such plan had all compensation from Duke and its Affiliates following the applicable Hire Date been taken into account) are not provided under the Duke Canadian Pension Plan for the period preceding the applicable Hire Date. If Duke or an Affiliate of Duke provides coverage under a group health plan to a Continuing Empress System Employee, then Duke shall cause such group health plan to (A) make available such coverage to such Continuing Empress System Employee and his or her eligible dependents effective immediately upon such Continuing Empress System Employee’s Hire Date, and (B) waive any preexisting condition restrictions to the extent such restrictions were not imposed with respect to such Continuing Empress System Employee and his or her eligible dependents, as applicable, under the corresponding COP Plan, and waive any proof of insurability requirements (and accept any pre-approvals of coverage) for amounts of insurance already approved under the corresponding COP Plan or up to the non-evidence maximums in the group health plan of Duke and its Affiliates, whichever is greater.

(d) COP Canadian Pension Plan.

(i) Continuing Empress System Employees who are active participants in the COP Canadian Pension Plan, which is comprised of both a defined contribution and a defined benefit component, shall, effective as of the applicable Hire Date, cease participation in the COP Canadian Pension Plan and shall, effective as of the applicable Hire Date, become members of the pension plan or plans of Duke and its Affiliates applicable to similarly situated employees of Duke and its Affiliates (such plan or plans, the “Duke Canadian Pension Plan”). The Duke Canadian Pension Plan shall recognize Continuing Empress System Employees’ service as recognized under the COP Canadian Pension Plan as of the applicable Hire Date as unbroken continuous service with Duke and its Affiliates for all purposes under the Duke Canadian Pension Plan, including vesting and locking-in pursuant to the Employment Pension Plans Act (Alberta) and, to the extent provided in Section 11.1(c), benefit accrual. Effective as of the applicable Hire Date, but subject to the completion of the transfers described in Sections 11.1(d)(iii) and (iv), the Duke Canadian Pension Plan shall assume all of the obligations of the COP Canadian Pension Plan in respect of each Continuing Empress System Employee.

(ii) The actuary of the COP Canadian Pension Plan shall determine the amount of assets to be transferred from the defined benefit pension fund for the COP Canadian Pension Plan to the pension fund for the Duke Canadian Pension Plan as of the Applicable Closing Date (the “DB Transfer Amount”) in accordance with the actuarial methods and assumptions as set forth on Schedule 11.1(d)(ii) of the COP Disclosure Schedule, which determination (along with reasonable background data) shall be furnished to Duke. The DB Transfer Amount shall equal the greater of the going-concern liabilities and the solvency liabilities of the COP Canadian Pension Plan as of the Applicable Closing Date in respect of the Continuing Empress System Employees hired on that date. Duke shall within 30 days of receiving such determination and data notify COP of any disagreement with such determination. In the event that Duke does not notify COP of any such disagreement, such determination shall become final. In the event that Duke notifies COP that it disagrees with such determination and Duke and COP cannot reach agreement with respect to proper determination of the DB Transfer Amount, such determination shall be referred to and settled with final and binding effect by an independent actuary mutually agreeable to Duke and COP.

(iii) COP shall, as soon as practicable, make an application to the applicable governmental authorities for any and all required approvals to transfer both the accrued liabilities of the Continuing Empress System Employees under the COP Canadian Pension Plan and assets equal to the Pension Transfer Amount (as defined below) from the COP Canadian Pension Plan to the Duke Canadian Pension Plan. Within 30 days following receipt of all regulatory approvals required with respect to such transfer of assets (but in no event prior to final determination of the DB Transfer Amount), COP shall cause the trustee of the COP Canadian Pension Plan to transfer to the pension fund for the Duke Canadian Pension Plan an amount (the “Pension Transfer Amount”) of cash equal to the sum of: (1) the DB Transfer Amount, plus interest from the Applicable Closing Date to the date of such transfer (the “Pension Transfer Date”) at a rate per annum equal to the going-concern or solvency valuation rate, whichever is used in the determination of the DB Transfer Amount, compounded annually, reduced by any benefits paid to Continuing Empress System Employees under the terms of the COP Canadian Pension Plan during the period between the Applicable Closing Date and the Pension Transfer Date; and (2) the sum of the defined contribution balances in the COP Canadian Pension Plan as of the Pension Transfer Date in respect of each Continuing Empress System Employee who has entitlements under the defined contribution provisions of the COP Canadian Pension Plan. In the event the applicable government authorities will only approve the transfer of an amount that is less than the Pension Transfer Amount, then (i) COP shall cause such lesser amount to be transferred from the COP Canadian Pension Plan to the Duke Canadian Pension Plan and (ii) COP shall simultaneously pay, or cause an Affiliate of COP to pay, to Duke (or an Affiliate of Duke designated by Duke) the difference between the Pension Transfer Amount and the amount so transferred pursuant to clause (i) of this sentence.

(iv) Duke and COP shall enter into similar arrangements as described in the preceding provisions of this Section 11.1(d) for Continuing Empress System Employees whose Hire Date is after the Applicable Closing Date, mutatis mutandis.

(e) Duke shall be responsible for and hereby agrees to indemnify COP and its Affiliates from all losses, expenses, or Liabilities whatsoever, including severance costs and loss of benefits, arising from any: (i) wrongful or constructive dismissal claims made by or on behalf of Continuing Empress System Employees that are based on actions of Duke and its Affiliates taken on or after the Applicable Closing Date or in connection with the processes concerning offers of employment contemplated by Section 11.1(a), or (ii) long-term disability claims made after the Applicable Closing Date by or on behalf of any Continuing Empress System Employee, provided such Continuing Empress System Employee was not receiving short-term or long-term disability benefits as of the Applicable Closing Date.

(f) On or before each Continuing Empress System Employee’s Hire Date, COP shall take any necessary action to (x) fully vest as of such date such Continuing Empress System Employee in all restricted stock units, if any, that were granted prior to 2005 to such employee under COP’s restricted stock unit plan, and (y) provide for prorated vesting (based upon a fraction, the numerator of which shall be the number of full months elapsed from the date of granting through such date and the denominator of which shall be 12) as of such date in all such units that were granted to such employee in 2005. To the extent that any cash payment amount or shares of COP stock remain unpaid or unvested with respect to a Continuing Empress System Employee as of his or her Hire Date under the terms of COP’s long-term incentive program for employees in Canada and the ConocoPhillips Canada Employee Stock Ownership Plan, COP shall vest and distribute such payment or shares as soon as practicable following the applicable Hire Date.

(g) Duke agrees that any personal information provided by COP and its Affiliates to Duke and its Affiliates with respect to Empress System Employees shall be used and disclosed by Duke and its Affiliates only for those purposes for which the information was initially collected, in order to carry on the business being purchased from COP and, where the personal information concerns a former employee of COP and its Affiliates, to carry on the employment relationship, if any, between Duke and its Affiliates and such employee.

(h) Nothing in this Agreement shall require or be construed or interpreted as requiring Duke or any Affiliate of Duke to continue the employment of any of their employees (including Continuing Empress System Employees) following the Applicable Closing Date, or to prevent Duke or an Affiliate of Duke from changing the terms and conditions of employment (including compensation and benefits) of any of their employees (including Continuing Empress System Employees) following the Applicable Closing Date, subject to the requirements of this Section 11.1 and the provisions of any applicable collective bargaining agreement and applicable law.

(i) Notwithstanding the preceding provisions of this Section 11.1, this Section 11.1 shall not apply if an Empress Contingency existed on the First Closing Date and the Empress System Business was not transferred to Duke.

Section 11.2 Canadian Assets Employees. (a) Company shall cause all Canadian Assets Employees, and only the Canadian Assets Employees, to be employed by Canadian Holding Company or a Canadian Assets Subsidiary as of the Second Closing Date. From and after the Second Closing Date, the terms and conditions of employment of each non-

unionized Continuing Canadian Assets Employee shall be determined by Duke in its sole discretion, provided such terms and conditions are consistent with the provisions of this Section 11.2. In respect of the unionized Continuing Canadian Assets Employees, Canadian Holding Company or a Canadian Assets Subsidiary, as applicable, shall continue immediately after the Second Closing Date to be the employer and responsible party under any applicable collective bargaining agreement pursuant to the provisions of applicable labor legislation.

(b) On or before the Second Closing Date, Company shall take all actions necessary, if any, to cause (i) Canadian Holding Company and/or one or more Canadian Assets Subsidiaries to be the sole adopting or participating employers under the Company Plans (other than the Company Plans maintained primarily in the United States that cover Canadian Assets Employees who are United States expatriates) and (ii) Canadian Holding Company and all Canadian Assets Subsidiaries to cease to be adopting or participating employers under the Company Plans maintained primarily in the United States that cover Canadian Assets Employees who are United States expatriates.

(c) On and after the applicable Hire Date, Duke shall cause each Continuing Canadian Assets Employee to receive full credit for all service credited under the Company Plans for all purposes (including eligibility to participate, vesting and benefit accrual) under the corresponding employee benefit plans and policies of Duke and its Affiliates, including vacation, floating holidays, retirement, retiree medical, severance and welfare plans, provided that such service credit shall not be provided for purposes of benefit accrual under any defined benefit plan.

(d) Nothing in this Agreement shall require or be construed or interpreted as requiring Duke or any Affiliate of Duke to continue the employment of any of their employees (including Continuing Canadian Assets Employees) following the Second Closing Date, or to prevent Duke or an Affiliate of Duke from changing the terms and conditions of employment (including compensation and benefits) of any of their employees (including Continuing Canadian Assets Employees) following the Second Closing Date, subject to the provisions of any applicable collective bargaining agreement or applicable law.

Section 11.3 No Third-Party Beneficiaries. Without limiting the generality of Section 13.3, this Article XI is not intended to confer upon any Empress System Employee, Canadian Assets Employee or Continuing Employee any rights or remedies hereunder.

Clause (i) of the preceding sentence shall be applied with respect to Taxes, if any, for such period relating to capital (including net worth or long-term debt) or intangibles by reference to the level of such items on such Applicable Closing Date. The portion of any Taxes (or refunds) that are imposed on a periodic basis, payable for a period that begins on or before the Applicable Closing Date and ends after such Applicable Closing Date (or, for Canadian income Tax purposes in the case of PTC, that begins prior to the Applicable Closing and ends after such Applicable Closing) and not allocable to the portion of such period ending on such Applicable Closing Date (or, for Canadian income Tax purposes in the case of PTC, immediately prior to the Applicable Closing) shall be allocable to the portion of the period beginning after such Applicable Closing Date (or, for Canadian income Tax purposes in the case of PTC, at the Applicable Closing).

(b) If the amount of any Tax described in Section 12.16(a), or any refund thereof or credit therefor, is voluntarily redetermined or redetermined by a Taxing Authority, the principles of Section 12.16(a) shall apply to the amount as so redetermined.

Section 12.17 Predecessors and Successors. For purposes of this Article XII, any reference to a corporation shall include a reference to any limited liability company or corporation into which such corporation is merged, amalgamated or converted and any reference to a limited liability company shall include a reference to any corporation which merged into, or was converted into, such limited liability company or corporation.

Section 12.18 COP Tax Representations with respect to Empress System. Unless an Empress Contingency existed on the First Closing Date, COP hereby represents and warrants that, except (i) as disclosed in Schedule 12.18 of the COP Disclosure Schedule or (ii) to the extent that any breach, failure or inaccuracy, individually or in the aggregate, would not reasonably be expected to have a Material Adverse Effect on PTC or the assets or properties comprising the Empress System:

(a) All Tax Returns that are required to be filed by or with respect to PTC or with respect to the assets or properties comprising the Empress System have been duly filed with the appropriate Taxing Authority within the times and in the manner prescribed by applicable law, and all such Tax Returns are complete and accurate and reflect accurately all liability for Taxes of PTC or with respect to the assets or properties comprising the Empress System for the periods covered thereby.

(b) All Taxes due and payable by PTC or with respect to the assets or properties comprising the Empress System have been paid in full within the time required by applicable law, regardless of whether such Taxes have been assessed or are shown or required to be shown on any Tax Return. All assessments and reassessments in respect of Taxes that have been received by PTC or with respect to the assets or properties comprising the Empress System have been paid in full. Neither PTC nor ES Transferor has received any refund of Taxes to which it was not entitled.

(c) The liability for Taxes of PTC or with respect to the assets or properties comprising the Empress System has been assessed by all relevant Taxing Authorities for all periods up to and including those set forth in Section 12.18 of the COP Disclosure Schedule. The only taxation years of PTC or with respect to the assets or properties comprising the Empress System that remain open for the assessment or reassessment of additional Taxes are those set out in Section 12.18 of the COP Disclosure Schedule. There are no outstanding agreements, arrangements, waivers or objections extending the statutory period or providing for an extension of time with respect to the assessment or reassessment of Taxes or the filing of any Tax Return or any payment of Taxes by or with respect to PTC or the assets or properties comprising the Empress System.

(d) Each of ES Transferor and PTC has withheld and collected all amounts required by applicable law to be withheld or collected by it on account of Taxes and has remitted all such amounts to the appropriate Taxing Authority within the time prescribed under any applicable Law.

(e) At the time of the Applicable Closing, the property nominally owned by PTC will be owned beneficially by CFC for Canadian income tax purposes, and for periods following the reorganization of the ownership of the Empress System separating title and beneficial ownership COP has consistently treated PTC for U.S. federal income tax purposes as not the tax owner of the property nominally owned by PTC.

Section 12.19 Company Tax Representations with respect to Canadian Assets Business. Company hereby represents and warrants to Duke that, except (i) as disclosed in Schedule 12.19 of the Company Disclosure Schedule or (ii) to the extent that any breach, failure or inaccuracy, individually or in the aggregate, would not reasonably be expected to have a Material Adverse Effect on the Canadian Holding Company, the Canadian Assets Subsidiaries, or on the assets or properties comprising the Canadian Assets Business:

(a) As of the date of this Agreement, all Tax Returns that are required to be filed by or with respect to the Canadian Holding Company or any of the Canadian Assets Subsidiaries or with respect to the assets or properties comprising the Canadian Assets Business have been duly filed and all such Tax Returns are complete and accurate.

(b) As of the date of this Agreement, all Taxes shown to be due on the Tax Returns referred to in clause (a) have been paid in full.

(c) As of the date of this Agreement, no waivers of statutes of limitation have been given by or requested with respect to any Tax Returns of the Canadian Holding Company or any of the Canadian Assets Subsidiaries or with respect to the assets or properties comprising the Canadian Assets Business.

Section 12.20 Tax Characterization of Transactions.

(a) Transactions in Connection with Formation of Company. Each of Duke, COP and Company shall (and agree that the affiliated group for U.S. federal income tax purposes that reports the income of each shall) (and Duke agrees that it shall cause Duke Energy and the affiliated group for U.S. federal income tax purposes that reports the income of Duke Energy to) take no action or position inconsistent with (or that could reasonably be expected to be viewed by the Internal Revenue Service as inconsistent with), and shall make or cause to be made all applicable elections with respect to: (i) the treatment of Company (or any successor thereto) as a partnership for U.S. federal income tax purposes and the treatment of each of the Flow Through Subsidiaries (or any successor thereto) as a partnership or disregarded entity for U.S. federal income tax purposes; (ii) the treatment of Company as not being a publicly traded partnership for United States federal income tax purposes; (iii) for all periods (or portions thereof) prior to the First Closing, the allocation of the Financing under Regulation Section 1.752-3(a)(3) among the Members in proportion to their Percentage Interests as of the Contribution Date; (iv) the treatment of the contribution to the Company by DEFS Holding pursuant to Section 2.2 of the Contribution Agreement as a contribution pursuant to Code Section 721, the treatment of the distribution to DEFS Holding pursuant to Section 3.2(c)(2) of the Contribution Agreement (as adjusted pursuant to Section 3.3 thereof) as a distribution pursuant to Code Section 731 and the treatment that, for purposes of the Code, neither such contribution nor such distribution is a transfer that constitutes a sale or exchange (or portion thereof) of property in whole or in part to

the Company by a Member in the Company acting in a capacity other than as a Member of the Company; and (v) the treatment of the contribution to the Company by CPGC pursuant to the CPGC Contribution as a contribution pursuant to Code Section 721, the treatment of the CPGC Distribution as a distribution pursuant to Code Section 731 and the treatment that, for purposes of the Code, neither the CPGC Contribution nor the CPGC Distribution is a transfer that constitutes a sale or exchange (or portion thereof) of property in whole or in part to the Company by a Member in the Company acting in a capacity other than as a Member of the Company (except in the case of this clause (v) that Duke, COP and the Company shall (and agree that the affiliated group for U.S. federal income tax purposes that reports the income of each shall) (and Duke agrees that it shall cause Duke Energy and the affiliated group for U.S. federal income tax purposes that reports the income of Duke Energy to) treat (except to the extent Duke, COP, the Members and the Company agree in writing or are required by a neutral nationally-recognized law firm or accounting firm designated by Duke and COP by mutual agreement (the “Neutral Firm”) to treat otherwise) an amount of the CPGC Distribution equal to the Disguised Sale Amount as proceeds of a sale by CPGC to the Company under Code Section 707(a) and an amount of the CPGC Contribution equal in fair market value to the Disguised Sale Amount as property that is sold by CPGC to the Company under Code Section 707(a) (such property treated as having been sold having regular federal income tax basis equal to the aggregate regular Federal income tax basis of the property contributed in the CPGC Contribution multiplied by a fraction the numerator of which is the Disguised Sale Amount and the denominator of which is the value of the property contributed in the CPGC Contribution, such value being for this purpose $2,139,500,000)). Capitalized terms used in this Section 12.20(a) but not otherwise defined in this Agreement shall have the meanings ascribed to them in the Second Amended and Restated LLC Agreement.

(b) Transactions Pursuant to this Agreement. For U.S. federal income tax purposes, Duke, COP and Company agree to file (and agree that the affiliated group for U.S. federal income tax purposes that reports the income of each shall file) (and Duke agrees that it shall cause Duke Energy and the affiliated group for U.S. federal income tax purposes that reports the income of Duke Energy to file) their respective federal income Tax Returns on a basis that is consistent, and agree not to take (and agree that the affiliated group for U.S. federal income tax purposes that reports the income of each shall not take) (and Duke agrees that it shall cause Duke Energy and the affiliated group for U.S. federal income tax purposes that reports the income of Duke Energy not to take) any position for U.S. federal income tax purposes that is inconsistent, with the following (in each case unless either (i) required to do otherwise pursuant to a “determination” within the meaning of Section 1313(a) of the Code (or any similar provision of state, local or foreign Tax law) or (ii) there is a change in applicable law or regulation):

(1) The fair market value of the membership interests in Company as of December 31, 2004 was $6,797,969,547 plus an amount determined by dividing the COP Excess Canadian Cash by 30.3%.

(2) The sale of the Subject Company Equity Interest by DEFS Holding to COP Transferee will be treated as a sale by a partner of an interest in a partnership to which Sections 741 and 751 of the Code apply. The fair market value of the Subject Company Equity Interest as of December 31, 2004 was $440 million.

(3) The distribution of 100% of the TEPPCO GP Sale Proceeds Amount by Company to DEFS Holding will be treated as a distribution to DEFS Holding of money to which Sections 731(a), 733 and 751 of the Code apply; provided, however, that for purposes of Section 751(b), the interest in Company property of each of DEFS Holding and CPGC after the transactions contemplated by this Agreement shall be determined (i) giving effect to the adjustment to the Book Value (as defined in the Second Amended and Restated LLC Agreement) of all Company assets by reason of clauses (1)(A) and (1)(B) of such definition and (ii) taking into account reverse Code Section 704(c) allocations.

(4) The distribution of the Equity Interests in the Canadian Holding Company by Company to DEFS Holding will be treated as a distribution by a partnership of property to a partner to which Sections 731(a), 731(b), 732(a) and 733 of the Code apply. The fair market value of the Equity Interests in the Canadian Holding Company as of the Second Closing Date is equal to $300 million plus an amount determined by dividing the COP Excess Canadian Cash by 30.3%.

(5) The purchase by Duke Transferee of the Empress System Business will be treated as a purchase of the Empress System Business from ES Transferor for $233 million and the assumption by Duke Transferee of the Assumed Liabilities.

(6) The contribution of the Second Closing Cash Amount in cash by CPGC to Company pursuant to Section 2.2(d) will be treated as a contribution of money by a partner to a partnership to which Sections 721 and 722 of the Code apply.

(7) The transactions described in Section 12.20(b)(2), (3), (4) and (6) will result in a reduction in the DEFS Holding’s Percentage Interest from 69.7% to 50% based upon the values of such transactions and of the membership interests in Company set forth above, subject to any adjustment to such values as agreed by the parties.

(8) The purchase price paid for the Empress System Business (including the Assumed Liabilities) shall be allocated among the Empress System Business in accordance with a schedule to be agreed upon by Duke and COP within 60 days following the Empress Closing (provided that, if Duke and COP have not agreed on such schedule by such date then such schedule shall be determined by the Neutral Firm) and such allocation schedule shall be used in filing all United States Federal Income Tax Returns, including Internal Revenue Service Form 8594, and all Canadian Income Tax Returns.

(9) Any contribution of cash pursuant to Section 3.3(a)(ii) by Company to Canadian Holding Company will be treated as a contribution to a corporation to which Section 351 of the Code applies.

(10) Any distribution of cash pursuant to Section 3.3(b) to DEFS Holding and CPGC will be treated as a distribution by a partnership to which Sections 731(a) and 733 of the Code apply, and any contribution of cash pursuant to Section 3.3(b) by DEFS Holding and CPGC will be treated as a contribution to a partnership to which Section 721 of the Code applies.

Section 12.21 Intentionally Omitted. This Section 12.21 has been intentionally omitted.

Section 12.22 Canadian Tax Matters.

(a) ES Transferor and Duke Transferee will, on or before the Empress Closing Date, jointly execute an election, in prescribed form and containing the prescribed information, to have subsection 167(1) of the Excise Tax Act (Canada) and any equivalent, analogous or corresponding provision under any applicable provincial or territorial legislation imposing a similar value added or multi-staged tax apply to the sale and purchase of the Empress System Business hereunder. ES Transferor and Duke Transferee will make such elections in prescribed form containing prescribed information and Duke Transferee shall file such election(s) in compliance with the requirement of the applicable law.

(b) ES Transferor and Duke Transferee will jointly complete and execute elections under section 22 of the Income Tax Act (Canada) and under any equivalent, analogous or corresponding provision under applicable Canadian provincial or territorial legislation as to the sale of any accounts receivable comprising the Empress System as soon as practicable following the Empress Closing Date, but in any event no later than 30 days prior to the earliest time that either ES Transferor or Duke Transferee is required to file its tax return under the Income Tax Act (Canada) or provincial taxing legislation for the taxation year in which the Empress Closing Date occurs. Such elections will designate therein the applicable portion of the purchase price as the consideration paid by ES Transferor for such accounts receivable in accordance with the allocation made pursuant to Section 12.20(b)(8) and ES Transferor and Duke Transferee will each file such election in a timely manner.

(c) ES Transferor and Duke Transferee shall, if so requested by Duke Transferee, file in mutually agreeable form elections under subsection 20(24) of the Income Tax Act (Canada) and under any equivalent, analogous or corresponding provision under applicable Canadian provincial or territorial legislation, in the form and manner and within the time prescribed by applicable law, with respect to undertakings arising from the operation of the Empress System Business and which undertakings are of the type described in subsection 20(24) of the Income Tax Act (Canada). ES Transferor and Duke Transferee acknowledge that ES Transferor is transferring assets to Duke Transferee which have a value equal to the amount specified pursuant to Section 12.20(b)(8) as consideration for the assumption by Duke Transferee of ES Transferor’s obligations in respect of such undertakings.

(d) To the extent legally able to do so, ES Transferor shall deliver any certificates required by the sales tax legislation of any province to the effect that all requisite taxes and other amounts under the relevant sales tax legislation have been paid by ES Transferor.

Section 12.23 Covenant of Duke.

(a) No member of the Duke Group shall take any action or position that is inconsistent with the representations contained in Section 12.18(e).

(b) Duke Transferee (for purposes of the transfer of the Empress System from CFC) will be registered under Part IX of the Excise Tax Act (Canada) before the Applicable Closing Date.

Section 12.24 Coordination. To the extent there is a conflict between Annex B of the Contribution Agreement and this Article XII (or to the extent the provisions of Annex B of the Contribution Agreement and this Article XII do not assign the obligation, control right or refund with respect to any Tax to the same Party), the provisions of this Article XII shall control. Section 8.3(d) of the Second Amended and Restated LLC Agreement and any other provisions in that Agreement regarding the Tax Committee are for the benefit of COP and Duke and shall not be amended without their consent. If any Transfer (as defined in the Second Amended and Restated LLC Agreement) of a Company Interest (as defined in the Second Amended and Restated LLC Agreement) that is owned by COP (or any of its Affiliates) (a “COP Transfer”), on one hand, or Duke (or any of its Affiliates) (a “Duke Transfer”), on the other hand, would result in a termination of the Company pursuant to Section 708(b)(1)(B) of the Code, such Transfer shall not be made without the prior written consent of Duke (in the case of a COP Transfer) or COP (in the case of a Duke Transfer).

ARTICLE XIII

MISCELLANEOUS

(c) To the extent that any Party has or hereafter may acquire any immunity from jurisdiction of any court or from any legal process (whether through service or notice, attachment prior to judgment, attachment in aid of execution, execution or otherwise) with respect to itself or its property, each Party hereby irrevocably waives such immunity in respect of its obligations with respect to this Agreement.

(d) Each Party waives, to the fullest extent permitted by applicable law, any right it may have to a trial by jury in respect of any action, suit or proceeding arising out of or relating to this Agreement.

Section 13.3 Entire Agreement. This Agreement and the schedules and exhibits hereto, together with the Confidentiality Agreement between Duke Capital LLC and ConocoPhillips dated February 2, 2005, contain the entire agreement between the Parties with respect to the subject matter hereof and supercedes in all respects the Term Sheet between Duke Energy and COP dated February 23, 2005, which has been terminated pursuant to the Term Sheet Termination Agreement, and there are no agreements, understandings, representations or warranties between the Parties other than those set forth or referred to herein. Except for Sections 7.9 and 7.12, Article X and Article XII, which are intended to benefit, and to be enforceable by, any of the indemnified parties thereunder, this Agreement is not intended to confer upon any Person not a Party (and their successors and assigns) any rights or remedies hereunder.

Section 13.6 Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the Parties and their respective successors and permitted assigns; provided, however, that no Party will assign its rights or delegate any or all of its obligations under this Agreement without the express prior written consent of each other Party.

Section 13.7 Headings; Definitions. The Section and Article headings contained in this Agreement are inserted for convenience of reference only and will not affect the meaning or interpretation of this Agreement. All references to Sections or Articles contained herein mean Sections or Articles of this Agreement unless otherwise stated. All capitalized terms defined herein are equally applicable to both the singular and plural forms of such terms.

Section 13.8 Amendments and Waivers. This Agreement may not be modified or amended except by an instrument or instruments in writing signed by the Parties. All other Parties may, only by an instrument in writing, waive compliance by a Party with any term or provision of this Agreement on the part of such Party hereto to be performed or complied with. The waiver by the Parties of a breach of any term or provision of this Agreement shall not be construed as a waiver of any subsequent breach. Except as otherwise expressly provided herein, no failure to exercise, delay in exercising or single or partial exercise of any right, power or remedy by any Party, and no course of dealing between the Parties, shall constitute a waiver of any such right, power or remedy.

Section 13.9 Schedules. The disclosure or inclusion of any matter or item in any Schedule to the COP Disclosure Schedule, the Duke Disclosure Schedule or the Company Disclosure Schedule shall not be deemed an acknowledgment or admission that any such matter or item is required to be disclosed or is material for purposes of the representations and warranties set forth in this Agreement or whether the subject matter of such disclosure may have a Material Adverse Effect on the Canadian Assets Business or the Empress System

Business. None of COP, Duke or Company shall be prejudiced in any manner whatsoever by, and no presumptions shall be created by virtue of, any disclosure of any matter in the COP Disclosure Schedule, the Duke Disclosure Schedule or the Company Disclosure Schedule, respectively, which is not expressly required to be disclosed under this Agreement. Information disclosed in any schedule hereto shall only constitute a disclosure with respect to the specific Section of this Agreement in which such schedule is referenced.

Section 13.10 Severability. If any provision of this Agreement shall be held invalid, illegal or unenforceable, the validity, legality or enforceability of the other provisions of this Agreement shall not be affected thereby, and there shall be deemed substituted for the provision at issue a valid, legal and enforceable provision as similar as possible to the provision at issue.

Section 13.11. Interpretation. For the purposes of this Agreement, “knowledge” shall mean, with respect to COP, except as otherwise specified in this Agreement, the actual knowledge (after due inquiry) of the persons identified in Schedule 13.11 of the COP Disclosure Schedule, with respect to Company, the actual knowledge (after due inquiry) of the persons identified in Schedule 13.11 of the Company Disclosure Schedule, and with respect to Duke, the actual knowledge (after due inquiry) of the persons identified in Schedule 13.11 of the Duke Disclosure Schedule. The phrase “including” shall be deemed to be followed by “without limitation.” The words “hereof,” “hereby,” “herein,” “hereunder” and similar terms in this Agreement shall refer to this Agreement as a whole and not any particular Section or article in which such words appear. For the avoidance of doubt, the term “applicable law” or “applicable laws” shall be deemed to refer to applicable laws in both the United States and Canada, in addition to any other applicable laws. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the Parties and no presumption or burden of proof shall arise favoring or disfavoring any Party by virtue of the authorship of any provisions of this Agreement.

Section 13.12 Specific Performance. The Parties agree that irreparable damage would occur in the event that any Party fails to consummate the transactions contemplated by this Agreement in accordance with the terms of this Agreement and that the Parties shall be entitled to specific performance in such event, in addition to any other remedy at law or in equity.
