WHEREAS, the Parties intend that the Internal Contributions, the Internal Distributions, the Contribution and the Distribution will qualify under Sections 355 and

WHEREAS, this Agreement sets forth the plans of reorganization and the process by which the Power Business and Gas Business will be reorganized and separated and, thereafter, all of the issued and outstanding shares of Spectra Energy Common Stock will be distributed to the holders of Duke Energy Common Stock;

WHEREAS, each of Duke Energy and Spectra Energy has determined that it is necessary and desirable to set forth the principal corporate transactions required to affect the reorganization, the Separation and the Distribution and to provide for other agreements that will govern certain other matters following the Effective Time.

Notwithstanding anything to the contrary in this Section 2.5(e), neither Party nor any member of their respective Group shall have any recourse, including any right to assert any claim or course of action, if, after the Effective Time, it is determined that the aggregate amount of cash and cash equivalents in the Spectra Energy Accounts at the Effective Time (subject to the exclusions referenced in the foregoing sentence) was more or less than the Spectra Energy Target Cash Amount.

(f) With respect to any outstanding checks issued by Duke Energy, Spectra Energy, or any of their respective Subsidiaries prior to the Effective Time, such outstanding checks shall be honored following the Effective Time by the entity or Group owning the account on which the check is drawn.

Section 2.6. Limitation of Liability.

(a) Except as otherwise expressly provided in this Agreement, no Party or any member of such Party’s Group shall have any Liability to any other Party or any member of each other Party’s Group in the event that any Information exchanged or provided pursuant to this Agreement (but excluding any such information included in a Disclosure Document) which is an estimate or forecast, or which is based on an estimate or forecast, is found to be inaccurate.

(b) Except as provided in Section 2.4, Section 2.11 or as set forth in subsection (c) below, no Party or any member of such Party’s Group shall have any Liability to any other Party or any member of such other Party’s Group based upon, arising out of or resulting from any Contract, arrangement, course of dealing or understanding existing on or prior to the Effective Time (other than this Agreement or any Ancillary Agreement or any Contract entered into in connection herewith or in order to consummate the transactions contemplated hereby or thereby), and each Party hereby terminates, and shall cause all members in its Group to terminate, any and all Contracts, arrangements, course of dealings or understandings between it or any members in its Group and the other Party, or any members of its Group, effective as of the Effective Time (other than this Agreement or any Ancillary Agreement or any Contract entered into in connection herewith or in order to consummate the transactions contemplated hereby or thereby), unless such Contract, arrangement, course of dealing or understanding is set forth in any Ancillary Agreement or on Schedule 2.6(b), and any such Liability, whether or not in writing, which is not reflected in any Ancillary Agreement or on such Schedule, is hereby irrevocably cancelled, released and waived effective as of the Effective Time.

(ii) any Contract, agreements, arrangements, commitments or understandings to which any non-wholly-owned Subsidiary or non-wholly-owned Affiliate of Duke Energy or Spectra Energy is a Party.

Section 2.7. Transfers Not Effected On or Prior to the Effective Time; Transfers Deemed Effective as of the Effective Time.

(a) To the extent that any transfers contemplated by this ARTICLE II shall not have been consummated on or prior to the Effective Time, the Parties shall cooperate to affect such transfers as promptly following the Effective Time as shall be practicable. Nothing herein shall be deemed to require the transfer of any Assets or the assumption of any Liabilities which by their terms or operation of Law cannot be transferred; provided, however, that the Parties shall, and shall cause the respective members of their Groups to, cooperate and use commercially reasonable efforts to seek to obtain any necessary Consents or Governmental Approvals for the transfer of all Assets and Liabilities contemplated to be transferred or assumed pursuant to this ARTICLE II. In the event that any such transfer or assumption of Assets or Liabilities has not been consummated from and after the Effective Time (i) the Party (or relevant member in its Group) retaining such Asset shall thereafter hold (or shall cause such member in its Group to hold) such Asset for the use and benefit of the Party (or relevant member in its Group) entitled thereto (at the expense of the Person entitled thereto) and (ii) the Party intended to assume such Liability shall, or shall cause the applicable member of its Group to, pay or reimburse the Party (or the relevant member of its Group) retaining such Liability for all amounts paid or incurred in connection with the retention of such Liability. In addition, the Party retaining such Asset or Liability (or relevant member of its Group) shall (or shall cause such member in its Group to) treat, insofar as reasonably possible and to the extent permitted by applicable Law, such Asset or Liability in the ordinary course of business in accordance with past practice and take such other actions as may be reasonably requested by the Party to which such Asset or Liability is to be transferred or assumed in order to place such Party, insofar as reasonably possible, in the same position as if such Asset or Liability had been transferred or assumed as contemplated hereby and so that all the benefits and burdens relating to such Asset or Liability, including possession, use, risk of loss, potential for gain, and dominion, control and command over such Asset or Liability, are to inure from and after the Effective Time to the relevant member of the Duke Energy Group or the Spectra Energy Group, as the case may be, entitled to the receipt of such Asset or Liability.

(b) If and when the Consents, Governmental Approvals and/or conditions, the absence or non-satisfaction of which caused the deferral of transfer of any Asset or assumption of any Liability pursuant to Section 2.7(a), are obtained or satisfied, the transfer, assignment or novation of the applicable Asset or Liability shall be effected in accordance with and subject to the terms of this Agreement and/or the applicable Ancillary Agreement as promptly as practical after the receipt of such Consents, Governmental Approvals and/or absence or satisfaction of conditions.

(c) The Party (or relevant member of its Group) retaining any Asset or Liability due to the deferral of the transfer or assignment of such Asset or the deferral of the assumption of such Liability pursuant to Section 2.7(a) shall not be obligated, in connection with the foregoing, to expend any money unless the necessary funds are advanced, or agreed in advance to be reimbursed by the Party (or relevant member of its Group) entitled to such Asset, other than reasonable attorneys’ fees and recording or similar fees, all of which shall be promptly reimbursed by the Party entitled to such Asset (or relevant member of its Group).

(d) On and prior to the twenty-four (24) month anniversary of the Effective Time, as applicable, if any Party determines that it owns (or any member of its Group) any Asset that was allocated by the terms of this Agreement to the other Party or that is agreed by such Party and the other Party in their good faith judgment to be an Asset that more properly belongs to the other Party (other than (for the avoidance of doubt), as between any two Parties, for any Asset acquired from an unaffiliated third party by a Party or member of such Party’s Group following the Effective Time), then the Party owning such Asset shall transfer, contribute, assign, distribute, and convey, or shall cause any such Asset to be transferred, contributed, assigned, distributed and conveyed, to the Party (or relevant member of its Group) identified as the appropriate transferee and following such transfer, contribution, assignment, distribution or conveyance, such Asset shall be a Gas Asset or Power Asset, as the case may be. In connection with such transfer, contribution, assignment, distribution or conveyance, the receiving party shall assume all Liabilities related to such asset. Following the twenty-four (24) month anniversary of the Effective Time, no Party (or relevant member of its Group) shall be obligated to transfer any newly recognized Asset that would, had such Asset been recognized at the Effective Time, have been transferred to the other Party (or relevant member of its Group).

(e) After the Effective Time, each Party (or any member of its Group) may receive mail, telegrams, packages and other communications properly belonging to the other Party (or any member of its Group). Accordingly, at all times after the Effective Time, each Party authorizes the other Party (or any member of its Group) to receive and open all mail, telegrams, packages and other communications received by such Party (or any member of its Group) and not unambiguously intended for such first Party, any member of such first Party’s Group or any of their respective officers, directors, employees or other agents, and to the extent that they do not relate to the business of the receiving Party, the receiving party shall promptly deliver such mail, telegrams, packages or other communications (or, in case the same relate to both businesses, copies thereof) to the other Party as provided for in Section 11.6. The provisions of this Section 2.7(e) are not intended to, and shall not, be deemed to constitute an authorization by any Party (or any member of its Group) to permit the other to accept service of process on its (or its members’) behalf and no Party (or any member of its Group) is or shall be deemed to be the agent of the other Party (or any member of its Group) for service of process purposes.

Section 2.8. Conveyancing and Assumption Instruments. In connection with, and in furtherance of, the assignments, distributions, transfers and conveyances of Assets and the acceptance and assumptions of Liabilities contemplated by this Agreement, the Parties shall execute or cause to be executed, on or prior to the Effective Time, by the appropriate entities, the Conveyancing and Assumption Instruments necessary to evidence the valid and effective assumption by the applicable Party (or any member of its Group) of its assumed Liabilities, and the valid transfer, contribution, assignment, distribution and conveyance to the applicable Party (or member of such Party’s Group) of all right, title and interest in and to its accepted Assets, including the transfer of real property with quit claim deeds, as may be appropriate.

Section 2.9. Further Assurances.

(a) In addition to and without limiting the actions specifically provided for elsewhere in this Agreement, including Section 2.7, each of the Parties shall cooperate with each

other and use (and will cause the relevant member of its Group to use) commercially reasonable efforts, prior to, on and after the Effective Time, to take, or to cause to be taken, all actions, and to do, or to cause to be done, all things reasonably necessary on its part under applicable Law or contractual obligations to consummate and make effective the transactions contemplated by this Agreement and the Ancillary Agreements.

(b) Without limiting the foregoing, each Party shall cooperate with the other Party, from and after the Effective Time, to execute and deliver, or use commercially reasonable efforts to cause to be executed and delivered, all instruments, including instruments of conveyance, assignment and transfer, and to make all filings with, and to obtain all Consents and/or Governmental Approvals, any permit, license, Contract, indenture or other instrument (including any Consents or Governmental Approvals), and to take all such other actions as such Party may reasonably be requested to take by any other Party from time to time, consistent with the terms of this Agreement and the Ancillary Agreements, in order to effectuate the provisions and purposes of this Agreement and the Ancillary Agreements and the conveyances, assignments and transfers of the applicable Assets and the assignment and assumption of the applicable Liabilities and the other transactions contemplated hereby and thereby. Without limiting the foregoing, each Party will, at the reasonable request, of the other Party, take such other actions as may be reasonably necessary to vest in such other Party good and marketable title to the Assets allocated to such Party under this Agreement or any of the Ancillary Agreements, free and clear of any Security Interest, if and to the extent it is practicable to do so.

Section 2.10. Novation of Liabilities; Consents.

(a) Each Party, at the request of the other Party, shall use commercially reasonable efforts to obtain, or to cause to be obtained, any Consent, release, substitution or amendment required to novate or assign all obligations under Contracts, licenses and other obligations or Liabilities for which a member of such Party’s Group and a member of the Party’s Group are jointly or severally liable and that do not constitute Liabilities of such other Party as provided in this Agreement (such other Party, the “Other Party”), or to obtain in writing the unconditional release of all parties to such arrangements (other than any member of the Group who assumed or retained such Liability as set forth in this Agreement), so that, in any such case, the members of the applicable Group will be solely responsible for such Liabilities; provided, however, that no Party shall be obligated to pay any consideration therefor to any third party from whom any such Consent, substitution or amendment is requested (unless such Party is fully reimbursed by the requesting Party).

(b) If the Parties are unable to obtain, or to cause to be obtained, any such required Consent, release, substitution or amendment, the Other Party or a member of such Other Party’s Group shall continue to be bound by such Contract, license or other obligation that does not constitute a Liability of such Other Party and, unless not permitted by Law or the terms thereof, as agent or subcontractor for such Party, the Party or member of such Party’s Group who assumed or retained such Liability as set forth in this Agreement (the “Liable Party”) shall, or shall cause a member of its Group to, pay, perform and discharge fully all the obligations or other Liabilities of such Other Party or member of such Other Party’s Group thereunder from and after the Effective Time; provided, however, that the Other Party shall not be obligated to extend, renew or otherwise cause such Contract, license or other obligation to remain in effect beyond

the term in effect as of the Effective Time. The Liable Party shall indemnify each Other Party and the members of such Other Party’s Group and hold each of them harmless against any and all Liabilities arising in connection therewith; provided, that the Liable Party shall have no obligation to indemnify the Other Party or any member of such Other Party’s Group with respect to any matter to the extent that such Other Party has engaged in any knowing violation of Law, fraud or misrepresentation in connection therewith. The Other Party shall, without further consideration, promptly pay and remit, or cause to be promptly paid or remitted, to the Liable Party or to another member of the Liable Party’s Group, all money, rights and other consideration received by it or any member of its Group in respect of such performance by the Liable Party (unless any such consideration is an Asset of such Other Party pursuant to this Agreement). If and when any such Consent, release, substitution or amendment shall be obtained or such agreement, lease, license or other rights or obligations shall otherwise become assignable or able to be novated, the Other Party shall promptly assign, or cause to be assigned, all rights, obligations and other Liabilities thereunder of any member of such Other Party’s Group to the Liable Party or to another member of the Liable Party’s Group without payment of any further consideration and the Liable Party, or another member of such Liable Party’s Group, without the payment of any further consideration, shall assume such rights and Liabilities.

Section 2.11. Guarantees.

(a) Duke Energy shall (with the commercially reasonable cooperation of Spectra Energy and the other members of the Spectra Energy Group) use its commercially reasonable efforts, if so requested by Spectra Energy, to have any member of the Spectra Energy Group removed as guarantor of, or obligor for, any Power Liability, with respect to those guarantees listed or described on Schedule 2.11(a).

(b) Spectra Energy shall (with the commercially reasonable cooperation of Duke Energy and the other members of the Duke Energy Group) use its commercially reasonable efforts, if so requested by Duke Energy, to have any member of the Duke Energy Group removed as guarantor of, or obligor for, any Gas Liability, with respect to those guarantees listed or described on Schedule 2.11(b) (each of the releases referred to in paragraphs (a) and (b) of this subsection, a “Guaranty Release”).

(c) Until Duke Energy or Spectra Energy is able to obtain, or to cause to be obtained, any such required removal as set forth in clauses (a) and (b) of this Section 2.11, each of Duke Energy and Spectra Energy agree to use their commercially reasonable efforts to not renew or extend the term of, increase its obligations under, or transfer to a third party, any loan, guarantee, lease, contract or other obligation for which another Party is or may be liable unless (i) all obligations of such other Party and the other members of such Party’s Group with respect thereto are thereupon terminated by documentation reasonably satisfactory in form and substance to such other Party or (ii) in the event a Guaranty Release is not obtained and such first Party wishes to extend the term of such guaranteed loan, guarantee, lease, contract or other obligation then such first Party shall have the option of extending the term if it provides such security as is reasonably satisfactory to the guarantor under such guarantee.

(d) For the avoidance of doubt, each of the items listed or described on Schedule 2.11(a) are Power Liabilities and, notwithstanding whether the guarantees are removed pursuant to Section 2.11(a), such guarantees shall continue to be Power Liabilities and Duke Energy shall indemnify and hold harmless all Spectra Energy Indemnitees against any Indemnifiable Loss arising from or relating thereto in accordance with the provisions of ARTICLE VII.

(e) For the avoidance of doubt, each of the items listed or described on Schedule 2.11(b) are Gas Liabilities and, notwithstanding whether the guarantees are removed pursuant to Section 2.11(b), such guarantees shall continue to be Gas Liabilities and Spectra Energy shall indemnify and hold harmless all Duke Energy Indemnitees against any Indemnifiable Loss arising from or relating thereto in accordance with the provisions of ARTICLE VII.

(f) Each of the Parties shall, and shall cause the other members of their respective Groups to, use their commercially reasonable efforts evaluate or to assist the other Party in evaluating any guarantee required to be so evaluated by FIN 45.

Section 2.12. Canadian Exchangeco. Duke Energy Canada Call Co. and Duke Energy Canada Exchangeco Inc. (“Exchangeco”) shall be members of the Spectra Energy Group. On December 11, 2006, the holders of the requisite number of shares of Exchangeco (the “Exchangeable Shares”) voted to approve a Plan of Arrangement (the “Plan of Arrangement”) pursuant to which the terms governing the Exchangeable Shares were amended (the “Exchangeable Share Reorganization”) to reorganize the existing class of Exchangeable Shares into two new classes of exchangeable shares, one exchangeable for one share of Duke Energy Common Stock (the “PowerCo Exchangeable Shares”) and a fraction of a share (calculated to reflect the ratio of Spectra Energy Common Stock distributed in the Distribution) exchangeable for one share of Spectra Energy Common Stock (the “Spectra Energy Exchangeable Shares”). The Supreme Court of British Columbia will hold a hearing on December 15, 2006 to approve the Plan of Arrangement. Each of Spectra Energy and Duke Energy shall, and shall cause each member of the Spectra Energy Group and the Duke Energy Group to, as the case may be, cooperate with each member of the other Group to ensure the orderly administration of the exchange of PowerCo Exchangeable Shares for shares of Duke Energy Common Stock and Spectra Energy Exchangeable Shares for shares of Spectra Energy Common Stock and the payment of dividends on the PowerCo Exchangeable Shares and the Spectra Energy Exchangeable Shares, and any other matters contemplated by the documents and agreements executed by members of the Spectra Energy Group and members of the Duke Energy Group in connection with the Exchangeable Share Reorganization, all on the terms and subject to the conditions set forth therein. The Parties agree that, as soon as permitted pursuant to the terms and conditions governing the PowerCo Exchangeable Shares and the Spectra Energy Exchangeable Shares, the Parties shall use their commercially reasonable efforts to terminate Exchangeco and mandatorily exchange each outstanding share of PowerCo Exchangeable Shares and Spectra Energy Exchangeable Shares.

Section 2.13. Disclaimer of Representations and Warranties.

THE DISTRIBUTION

Section 4.1. Stock Dividend to Duke Energy; Distribution.

Prior to the Distribution Date, Spectra Energy shall issue to Duke Energy as a stock dividend such number of shares of Spectra Energy Common Stock (or Duke Energy and Spectra Energy shall take or cause to be taken such other appropriate actions to ensure that Duke Energy has the requisite number of shares of Spectra Energy Common Stock) as may be requested by Duke Energy after consultation with Spectra Energy in order to effect the Distribution, which shares as of the date of issuance shall represent (together with such shares previously held by Duke Energy) all of the issued and outstanding shares of Spectra Energy Common Stock. Subject to conditions and other terms in this ARTICLE IV and the terms in Section 2.12, Duke Energy will cause the Agent on the Distribution Date to distribute all of the outstanding shares of Spectra Energy Common Stock then owned by Duke Energy to holders of Duke Energy Common Stock (on an as if converted basis) on the Record Date, and to credit the appropriate class and number of such shares of Spectra Energy Common Stock to book entry accounts for each such holder or designated transferee or transferees of such holder of Spectra Energy Common Stock. For stockholders of Duke Energy who own Duke Energy Common Stock through a broker or other nominee, their shares of Spectra Energy Common Stock will be credited to their respective accounts by such broker or nominee. Subject to conditions and other terms in this ARTICLE IV and the terms in Section 2.12, each holder of Duke Energy Common Stock on the Record Date (or such holder’s designated transferee or transferees) will be entitled to receive a number or a fraction of a share of Spectra Energy Common Stock for each share of Duke Energy Common Stock held by such stockholder as provided in the defined term “Distribution”, which distribution ratio has previously been determined by the Board of Directors of Duke Energy. No action by any such stockholder shall be necessary for such stockholder (or such stockholder’s designated transferee or transferees) to receive the applicable number of shares of (and, if applicable, cash in lieu of any fractional shares) Spectra Energy Common Stock such stockholder is entitled to in the Distribution.

Section 4.2. Fractional Shares. Duke Energy stockholders who, after aggregating the number of shares of Spectra Energy Common Stock (or fractions thereof) to which such stockholder would be entitled on the Record Date, would be entitled to receive a fraction of a share of Spectra Energy Common Stock in the Distribution, will receive cash in lieu of fractional shares. Fractional shares of Spectra Energy Common Stock will not be distributed in the Distributions nor credited to book-entry accounts. The Agent shall, as soon as practicable after the Distribution Date (a) determine the number of whole shares and fractional shares of Spectra Energy Common Stock allocable to each other holder of record or beneficial owner of Duke Energy Common Stock as of close of business on the Record Date, (b) aggregate all such

fractional shares into whole shares and sell the whole shares obtained thereby in open market transactions at then prevailing trading prices on behalf of holders who would otherwise be entitled to fractional share interests, and (c) distribute to each such holder, or for the benefit of each such beneficial owner, such holder or owner’s ratable share of the net proceeds of such sale, based upon the average gross selling price per share of Spectra Energy Common Stock after making appropriate deductions for any amount required to be withheld for United States federal income tax purposes. Spectra Energy shall bear the cost of brokerage fees and transfer taxes incurred in connection with these sales of fractional shares, which such sales shall occur as soon after the Distribution Date as practicable and as determined by the Agent. None of Duke Energy, Spectra Energy or the applicable Agent will guarantee any minimum sale price for the fractional shares of Spectra Energy Common Stock. Neither Duke Energy nor Spectra Energy will pay any interest on the proceeds from the sale of fractional shares. The Agent will have the sole discretion to select the broker-dealers through which to sell the aggregated fractional shares and to determine when, how and at what price to sell such shares. Neither the Agent nor the selected broker-dealers will be Affiliates of Duke Energy or Spectra Energy.

Section 4.3. Actions in Connection with the Distribution.

(a) Spectra Energy shall file such amendments and supplements to the Form 10 as Duke Energy may reasonably request, and such amendments as may be necessary in order to cause the same to become and remain effective as required by Law, including filing such amendments and supplements to the Form 10 and Information Statement as may be required by the Commission or federal, state or foreign securities Laws.

(d) Nothing in this Section 4.3 shall be deemed, by itself, to create a Liability of Duke Energy for any portion of the Form 10.

Section 4.4. Sole Discretion of Duke Energy. Duke Energy shall, in its sole and absolute discretion, determine the Distribution Date and all terms of the Distribution, including the form, structure and terms of any transactions and/or offerings to effect the Distribution and the timing of and conditions to the consummation thereof. In addition, Duke Energy may, in accordance with Section 11.11, at any time prior to the Distribution Date and from time to time until the completion of the Distribution decide to abandon the Distribution or modify or change the terms of the Distribution, including by accelerating or delaying the timing of the consummation of all or part of the Distribution. None of Spectra Energy, any other member of the Spectra Energy Group, any Spectra Energy Employee or any Third-Party shall have any right or claim to require the consummation of the Separation or the Distribution, each of which shall be effected at the sole discretion of the Board of Directors of Duke Energy.

Section 4.5. Conditions to Distribution. Subject to Section 4.4, the following are conditions to the consummation of the Distribution.

ARTICLE V

CERTAIN COVENANTS

Section 5.1. No Solicit. None of Duke Energy or Spectra Energy or any member of their respective Groups will from the Effective Time through and including the one year anniversary of the Effective Time, without the prior written consent of the other applicable Party, either directly or indirectly, on their own behalf or in the service or on behalf of others, solicit, aid, induce or encourage any individual who is an employee of any other Party’s respective Group to leave his or her employment; provided, however, that nothing in this Section 5.1 shall be deemed to prohibit, any general solicitation for employment through advertisements and search firms not specifically directed at employees of such other applicable Party; provided further, that the applicable Party has not encouraged or advised such firm to approach any such employee.

Section 5.2. Legal Names and Other Parties’ Trademark.

(a) Except as otherwise specifically provided in any Ancillary Agreement, as soon as reasonably practicable after the Distribution Date, but in any event within three (3) months thereafter, each Party shall cease (and shall cause all of the other members of its Group to cease): (i) making any use of any names or Trademarks that include (A) any of the Trademarks of the other Party or such other Party’s Subsidiaries or Affiliates (including, in the case of Spectra Energy, “Duke Energy” or “Duke Energy Corporation” or any other name or Trademark containing the word “Duke”) and (B) any names or Trademarks related thereto including any names or Trademarks confusingly similar thereto or dilutive thereof (with respect to each Party, such Trademarks of the other Party or any of such other Party’s Subsidiaries or Affiliates, the “Other Party Marks”), and (ii) holding themselves out as having any affiliation with the other Party or such other Party’s Subsidiaries or Affiliates; provided, however, that the foregoing shall not prohibit any Party or any member of a Party’s Group from (1) stating in any advertising or any other communication that it is formerly a Duke Energy affiliate or (2) making use of any Other Party Xxxx in a manner that would constitute “fair use” under applicable Law if any unaffiliated third party made such use or would otherwise be legally permissible for any unaffiliated third party without the consent of the Party owning such Other Party Xxxx. In furtherance of the foregoing, as soon as practicable, but in no event later than three (3) months

following the Distribution Date, each Party shall (and cause all of the other members of its Group to) remove, strike over or otherwise obliterate all Other Party Marks from all of such Party’s and its Subsidiaries’ and Affiliates’ assets and other materials, including any vehicles, business cards, schedules, stationery, packaging materials, displays, signs, promotional materials, manuals, forms, websites, email, computer software and other materials and systems; provided, however, that Spectra Energy shall promptly after the Distribution Date post a disclaimer on the “xx.xxxx-xxxxxx.xxx” website informing its customers that as of the Effective Time and thereafter Spectra Energy, and not Duke Energy, is responsible for the operation of the Gas Business, including such website and any applicable services. Any use by any Party or any of such Party’s Subsidiaries or Affiliates of any of the Other Party Marks as permitted in this Section 5.2 is subject to their compliance with all quality control and related requirements and guidelines in effect for the Other Party Marks as of the Effective Time.

(b) Notwithstanding the foregoing requirements of Section 5.2(a), if any Party or any member of such Party’s Group exercised good faith efforts to comply with Section 5.2(a) but is unable, due to regulatory or other circumstance beyond its control, to effect a legal name change in compliance with applicable Law such that an Other Party Xxxx remains in such Party’s or its Group member’s legal name, then such Party or its relevant Group member will not be deemed to be in breach hereof as long as it continues to exercise good faith efforts to effectuate such name change and does effectuate such name change within nine (9) months after the Distribution Date, and, in such circumstances, such Party or Group member may continue to include in its assets and other materials references to the Other Party Xxxx that is in such Party’s or Group member’s legal name which includes references to “Spectra Energy” or “Duke Energy” as applicable, but only to the extent necessary to identify such Party or Group member and only until such Party’s or Group member’s legal name can be changed to remove and eliminate such references.

(c) Notwithstanding the foregoing requirements of Section 5.2(a), Spectra Energy shall not be required to change any name including the word “Duke” in any third-party contract or license, or in property records with respect to real or personal property, if an effort to change the name is commercially unreasonable; provided, however, that (i) Spectra Energy on a prospective basis from and after the Distribution Date shall change the name in any new or amended third-party contract or license or property record and (ii) Spectra Energy shall not advertise or make public any continued use of the “Duke” name permitted by this Section 5.2(c).

Spectra Energy shall neither sublicense the Licensed Trademarks, nor shall Spectra Energy publish, distribute or otherwise use the Licensed Trademarks for any purpose other than the internal operations of the Gas Business. Spectra Energy shall ensure that in the course of conducting the Gas Business under any of the Licensed Trademarks, the quality of services provided by Spectra Energy under such Licensed Trademark will be at least equal to or greater than the quality of services provided by Duke Energy under such Licensed Trademark immediately prior to the Effective Time, and that such services shall otherwise be maintained and offered in a manner and

at a level consistent with such past practices. Spectra Energy shall use the Licensed Trademarks in accordance with sound trademark usage principles and all applicable Laws as reasonably necessary to maintain the validity and enforceability of Duke Energy’s rights in such trademarks and Spectra Energy shall not use the Licensed Trademarks in any manner which might tarnish, disparage, or reflect adversely on Duke Energy or the Licensed Trademarks. If Spectra Energy uses the Licensed Trademarks in a manner which Duke Energy, in its reasonable judgment, determines reflects adversely upon the image, goodwill and reputation of Duke Energy or the Licensed Trademarks, then, upon receipt of written notice from Duke Energy identifying its objection, Spectra Energy shall immediately cease the particular use to which Duke Energy has objected. Spectra Energy agrees to cooperate with and assist Duke Energy in protecting and enforcing Duke Energy’s rights in the Licensed Trademarks and in maintaining any registrations with any Governmental Entities for the Licensed Trademarks in force. Spectra Energy shall assist Duke Energy in the enforcement of rights in the Licensed Trademarks by promptly informing Duke Energy of any actual or potential claim, demand, infringement, misuse or misappropriation relating to the Licensed Trademarks to the extent that Spectra Energy is in possession of such information or otherwise becomes aware of any such actual or potential claim, demand, infringement, misuse or misappropriation. Duke Energy will have the sole right to determine whether or not to investigate such alleged infringement and to determine whether to initiate or participate in any judicial or administrative proceeding involving the Licensed Trademarks. Duke Energy is and shall remain the sole owner of the Licensed Trademarks and all goodwill associated therewith. Spectra Energy acknowledges that nothing herein gives Spectra Energy any right, title or interest in the Licensed Trademarks, apart from the license granted under this Section 5.2(d), and in no event shall Spectra Energy’s use of the Licensed Trademarks be deemed to vest any right, title or interest to the Licensed Trademarks in Spectra Energy. All uses of the Licensed Trademarks by Spectra Energy, and all goodwill generated thereby, shall inure exclusively and completely to the benefit of Duke Energy. Spectra Energy, agrees that it shall not contest or challenge the validity of, or Duke Energy’s title in, the Licensed Trademarks, and it shall not register or apply for registration of the Licensed Trademarks.

Section 5.3. Auditors and Audits; Annual and Quarterly Financial Statements and Accounting.

(a) Each Party agrees that during the period ending one hundred and eighty (180) days following the Distribution Date and in any event solely with respect to the preparation and audit of each of the Party’s financial statements for any of the years ended December 31, 2006, 2005 and 2004, the printing, filing and public dissemination of such financial statements, the audit of each Party’s internal control over financial reporting related to such financial statements and such Party’s management’s assessment thereof, and each Party’s management’s assessment of such Party’s disclosure controls and procedures related to such financial statements:

Oxley Act of 2002 and the Commission’s and Public Company Accounting Oversight Board’s rules and auditing standards thereunder (such assessments and audit being referred to as the “2006 Internal Control Audit and Management Assessments”). Without limiting the generality of the foregoing, each Party will provide all required financial and other Information with respect to itself and its Subsidiaries to its auditors in a sufficient and reasonable time and in sufficient detail to permit its auditors to take all steps and perform all reviews necessary to provide sufficient assistance to each other Party’s auditors with respect to information to be included or contained in such other Party’s annual financial statements and to permit such other Party’s auditors and management to complete the 2006 Internal Control Audit and Management Assessments.

(ii) Access to Personnel and Records. Each audited Party shall authorize, and use its commercially reasonable efforts to cause, its respective auditors to make available to each other Party’s auditors (each such other Party’s auditors, collectively, the “Other Parties’ Auditors”) both the personnel who performed or are performing the annual audits of such audited party (each such Party with respect to its own audit, the “Audited Party”) and work papers related to the annual audits of such Audited Party, in all cases within a reasonable time prior to such Audited Party’s auditors’ opinion date, so that the Other Parties’ Auditors are able to perform the procedures they consider necessary to take responsibility for the work of the Audited Party’s auditors as it relates to their auditors’ report on such other Party’s financial statements, all within sufficient time to enable such other Party to meet its timetable for the printing, filing and public dissemination of its annual financial statements. Each Party shall make available to the Other Parties’ Auditors and management its personnel and Records in a reasonable time prior to the Other Parties’ Auditors’ opinion date and other Parties’ management’s assessment date so that the Other Parties’ Auditors and other Parties’ management are able to perform the procedures they consider necessary to conduct the 2006 Internal Control Audit and Management Assessments.

(b) Amended Financial Reports. In the event a Party restates any of its financial statements that includes such Party’s audited or unaudited financial statements with respect to any balance sheet date or period of operation between January 1, 2003 and December 31, 2006, such Party will deliver to the other Party a substantially final draft, as soon as the same is prepared, of any report to be filed by such first Party with the Commission that includes such restated audited or unaudited financial statements (the “Amended Financial Report”); provided, however, that such first Party may continue to revise its Amended Financial Report prior to its filing thereof with the Commission, which changes will be delivered to the other Party as soon as reasonably practicable; provided, further, however, that such first Party’s financial personnel will actively consult with the other Party’s financial personnel regarding any changes which such first Party may consider making to its Amended Financial Report and related disclosures prior to the anticipated filing of such report with the Commission, with particular focus on any changes which would have an effect upon the other Party’s financial statements or related disclosures. Each Party will reasonably cooperate with, and permit and make any necessary employees available to, the other Party, in connection with the other Party’s preparation of any Amended Financial Reports.

(c) Financials; Outside Auditors. If any Party or member of its respective Group is required, pursuant to Rule 3-09 of Regulation S-X or otherwise, to include in its Exchange Act filings audited financial statements or other information of the other Party or

member of the other Party’s Group, the other Party shall use its commercially reasonable efforts (i) to provide such audited financial statements or other information, and (ii) to cause its outside auditors to consent to the inclusion of such audited financial statements or other information in the Party’s Exchange Act filings.

(d) Third Party Agreements. Nothing in this Section 5.3 shall require any Party to violate any agreement with any third party regarding the confidentiality of confidential and proprietary information relating to that third party or its business; provided, however, that in the event that a Party is required under this Section 5.3 to disclose any such information, such Party shall use commercially reasonable efforts to seek to obtain such third party’s consent to the disclosure of such information.

Section 5.4. No Restrictions on Post-Closing Competitive Activities; Corporate Opportunities.

(a) Except as expressly provided in Section 5.1 hereof, it is the explicit intent of each of the Parties that this Agreement shall not include any non-competition or other similar restrictive arrangements with respect to the range of business activities that may be conducted by the Parties. Accordingly, each of the Parties acknowledges and agrees that nothing set forth in this Agreement shall be construed to create any explicit or implied restriction or other limitation on (i) the ability of any Party hereto to engage in any business or other activity that competes with the business of any other Party, or (ii) the ability of any Party to engage in any specific line of business or engage in any business activity in any specific geographic area. Except as expressly provided in the Ancillary Agreements, Duke Energy and the Duke Energy Group shall have the right to, and shall have no duty not to, (i) engage in the same or similar business activities or lines of business as Spectra Energy and the Spectra Energy Group, (ii) do business with any client or customer of Spectra Energy and the Spectra Energy Group, and (iii) employ or otherwise engage any officer or employee of Spectra Energy and the Spectra Energy Group, and neither Duke Energy nor the Duke Energy Group nor any officer or director thereof shall be liable to Spectra Energy and the Spectra Energy Group or its stockholders for breach of any fiduciary duty by reason of any such activities of Duke Energy or the Duke Energy Group or of such person’s participation therein.

(b) In the event that Duke Energy or any other member of the Duke Energy Group acquires knowledge of a potential transaction or matter that may be a corporate opportunity for both Duke Energy or any other member of the Duke Energy Group and Spectra Energy or any other member of the Spectra Energy Group, neither Duke Energy nor any other member of the Duke Energy Group nor any agent or advisor thereof shall have any duty to communicate or present such corporate opportunity to Spectra Energy or any other member of the Spectra Energy Group and shall not be liable to Spectra Energy or any other member of the Spectra Energy Group or to Spectra Energy’s stockholders for breach of any fiduciary duty as a stockholder of Spectra Energy by reason of the fact that Duke Energy or any other member of the Duke Energy Group pursues or acquires such corporate opportunity for itself, directs such corporate opportunity to another person or entity, or does not present such corporate opportunity to Spectra Energy or any other member of the Spectra Energy Group.

(c) In the event that Spectra Energy or any other member of the Spectra Energy Group acquires knowledge of a potential transaction or matter that may be a corporate opportunity for both Duke Energy or any other member of the Duke Energy Group and Spectra Energy or any other member of the Spectra Energy Group, neither Spectra Energy nor any other member of the Spectra Energy Group nor any agent or advisor thereof shall have any duty to communicate or present such corporate opportunity to Duke Energy or any other member of the Duke Energy Group and shall not be liable to Duke Energy or any other member of the Duke Energy Group or to Duke Energy’s stockholders for breach of any fiduciary duty as a stockholder of Spectra Energy by reason of the fact that Spectra Energy or any other member of the Spectra Energy Group pursues or acquires such corporate opportunity for itself, directs such corporate opportunity to another person or entity, or does not present such corporate opportunity to Duke Energy or any other member of the Duke Energy Group.

(d) For the purposes of this Section 5.4, “corporate opportunities” of Spectra Energy or any other member of the Spectra Energy Group shall include, but not be limited to, business opportunities that Spectra Energy or any other member of the Spectra Energy Group are financially able to undertake, that are, by their nature, in a line of business of Spectra Energy or any other member of the Spectra Energy Group, including the Gas Business, are of practical advantage to them and are ones in which Spectra Energy or any other member of the Spectra Energy Group have an interest or a reasonable expectancy, and in which, by embracing the opportunities, the self-interest of Duke Energy or any other member of the Duke Energy Group or any of their officers or directors will be brought into conflict with that of Spectra Energy or any other member of the Spectra Energy Group, and “corporate opportunities” of Duke Energy or any other member of the Duke Energy Group shall include, but not be limited to, business opportunities that Duke Energy or any other member of the Duke Energy Group are financially able to undertake, that are, by their nature, in a line of business of Duke Energy or any other member of the Duke Energy Group, including the Power Business, are of practical advantage to them and are ones in which Duke Energy or any other member of the Duke Energy Group have an interest or a reasonable expectancy, and in which, by embracing the opportunities, the self-interest of Spectra Energy or any other member of the Spectra Energy Group or any of their officers or directors will be brought into conflict with that of Duke Energy or any other member of the Duke Energy Group.

Section 6.1. Unallocated Assets and Contingent Gains.

(a) As of the Effective Time, the Parties have identified no Unallocated Assets and there shall be a presumption that any Asset not explicitly addressed in this Agreement or set forth in the Schedules hereto is, nevertheless, intended to be either a Power Asset or a Gas Asset. Such presumption may only be overcome by clear and convincing evidence to the contrary.

(b) To the extent any benefit is received from any Unallocated Asset, that benefit (net of costs to realize) shall be shared among Duke Energy and Spectra Energy in proportion to the Duke Energy Percentage and the Spectra Energy Percentage, respectively, and shall be paid in accordance with Section 6.3.

(c) Contingent Gains not known as of the Effective Time shall be referred to the Contingent Claim Committee for determination pursuant to the provisions of Section 6.4 of whether the Contingent Gain is a Exclusive Duke Energy Contingent Gain, an Exclusive Spectra Energy Contingent Gain or an Unallocated Asset.

(d) As of the Effective Time, all Contingent Gains are identified in Schedules 1.1(57) and 1.1(59), and such Contingent Gains are either Power Assets or Gas Assets, as provided in Section 1.1(109)(vi) and Section 1.1(66)(vi), respectively. There shall be a presumption that any Contingent Gain not explicitly addressed in this Agreement or set forth in the Schedules hereto is, nevertheless, intended to be either a Power Asset or a Gas Asset. Such presumption may only be overcome by clear and convincing evidence to the contrary.

(e) Any Contingent Gain determined by the Contingent Claim Committee pursuant to Section 6.4 to be an Exclusive Duke Energy Contingent Gain shall be a Power Asset as provided in Section 1.1(109)(vi), and shall be administered by Duke Energy and Duke Energy shall have the sole right to any benefit therefrom.

(f) Any Contingent Gain determined by the Contingent Claim Committee pursuant to Section 6.4 to be an Exclusive Spectra Energy Contingent Gain shall be a Gas Asset as provided in Section 1.1(66)(vi), and shall be administered by Spectra Energy and Spectra Energy shall have the sole right to any benefit therefrom.

(g) Any Asset or Contingent Gain determined by the Contingent Claim Committee pursuant to Section 6.4 to be an Unallocated Asset shall be administered by Duke Energy. Duke Energy shall have sole and exclusive authority to commence, assign, prosecute, settle, manage, control, conduct, waive, forgo, release, discharge, forgive and otherwise determine all matters whatsoever with respect to any Unallocated Asset, it being understood that it is the present intent of the Parties that as soon as commercially practicable any Unallocated Asset shall be monetized and the proceeds distributed in accordance with Section 6.1(b). Spectra Energy shall not take, or permit any member of the Spectra Energy Group to take, any action (including commencing any claim) that would interfere with such rights and powers of any member of the Duke Energy Group.

(h) Duke Energy shall notify Spectra Energy in the event that it commences an Action with respect to an Unallocated Asset; provided that the failure to provide such notice shall not give rise to any rights on the part of Spectra Energy or against Duke Energy or affect any other provision of this Section 6.1. Spectra Energy acknowledges (i) that Duke Energy may elect not to pursue any action regarding any Unallocated Asset for any reason whatsoever (including a different assessment of the merits of any Action, claim or right than Spectra Energy might have or any business reasons that are in the best interests of Duke Energy or a member of the Duke Energy Group, without regard to the best interests of any member of the Spectra Energy Group), and (ii) that no member of the Duke Energy Group shall have any liability to any

Person (including any member of the Spectra Energy Group) as a result of any such determination.

Section 6.2. Unallocated Liabilities.

(a) As of the Effective Time, Schedule 1.1(146)(iii) sets forth all known Unallocated Liabilities and there shall be a presumption that any Liability not explicitly addressed in this Agreement or set forth in the Schedules hereto is, nevertheless, intended to be either a Power Liability or a Gas Liability. Such presumption may only be overcome by clear and convincing evidence to the contrary.

(b) Each of Duke Energy and Spectra Energy shall be responsible for its Allocated Percentage of any Unallocated Liability. It shall not be a defense to any obligation by any party to pay any amount in respect of any Unallocated Liability that such party was not consulted in the defense thereof, that such party’s views or opinions as to the conduct of such defense were not accepted or adopted, that such party does not approve of the quality or manner of the defense thereof or that such Unallocated Liability was incurred by reason of a settlement rather than by a judgment or other determination of liability; provided, however, that neither Party shall settle an Unallocated Liability in a manner which would restrict or limit the future conduct of the other Party’s business or operations without such other Party’s consent.

(c) As of the Effective Time, all known Contingent Liabilities are identified in Schedules 1.1(58) and 1.1(60), and such Contingent Liabilities are either Power Liabilities or Gas Liabilities pursuant to Section 1.1(112)(vii) and Section 1.1(69)(vi), respectively. The respective Party assigned a Contingent Liability as an Exclusive Duke Energy Contingent Liability or an Exclusive Spectra Energy Contingent Liability shall be solely responsible for managing the defense of the claim, including, without limitation, whether to settle, and shall have sole responsibility, as between the Spectra Energy Group and the Duke Energy Group, for the costs, expenses, liabilities and judgments associated with the Action, notwithstanding that any member of the Spectra Energy Group (with respect to an Exclusive Duke Energy Contingent Liability) or any member of the Duke Energy Group (with respect to an Exclusive Spectra Energy Contingent Liability) may have been named or remained a party defendant to the Action. There shall be a presumption that any Contingent Liability not explicitly addressed in this Agreement or set forth in the Schedules hereto is, nevertheless, intended to be either a Power Liability or a Gas Liability. Such presumption may only be overcome by clear and convincing evidence to the contrary.

(d) Contingent Liabilities not known as of the Effective Time, or otherwise not included in Schedules 1.1(58) and 1.1(60), shall be referred to the Contingent Claim Committee for determination pursuant to the provisions of Section 6.4 of whether the Contingent Liability is an Exclusive Duke Energy Contingent Liability, an Exclusive Spectra Energy Contingent Liability or an Unallocated Liability

(i) Any Contingent Liability determined by the Contingent Claim Committee pursuant to Section 6.4 to be an Exclusive Duke Energy Contingent Liability, shall be a Power Liability as provided in Section 1.1(112)(vii), and shall be administered

by Duke Energy and Duke Energy shall indemnify Spectra Energy from such Liability in accordance with ARTICLE VII.

(ii) Any Contingent Liability determined by the Contingent Claim Committee pursuant to Section 6.4 to be an Exclusive Spectra Energy Contingent Liability, shall be a Spectra Energy Liability as provided in Section 1.1(69)(vi), and shall be administered by Spectra Energy and Spectra Energy shall indemnify Duke Energy from such Liability in accordance with ARTICLE VII.

(iii) Except as set forth in Schedule 1.1(146)(iii), Duke Energy shall assume the defense of, and may seek to settle or compromise, any claim determined by the Contingent Claim Committee pursuant to Section 6.4 to be an Unallocated Liability, and the costs and expenses (including allocated costs of in-house counsel and other personnel) thereof shall be included in the calculation of the amount of the applicable Unallocated Liability in determining the reimbursement obligations of the other parties with respect thereto.

(e) Schedule 1.1(146)(iii) indicates, to the extent so identifiable on the date hereof, the Party that shall be responsible for administering each item set forth therein and any special procedures to be applied in administering or allocating the Liability associated with each Unallocated Liability set forth therein.

Section 6.3. Payments.

(a) Any amount owed in respect of any Unallocated Liabilities (including reimbursement for the cost or expense (including allocated costs of in-house counsel and other personnel) of defense of):

(i) any Third Party Claim that is an Unallocated Liability, or

(ii) any Unallocated Asset pursuant to this ARTICLE VI,

shall be remitted promptly after the Party entitled to such amount provides an invoice (including reasonable supporting information with respect thereto) to the party owing such amount.

(b) In the case of any Unallocated Liability, the Party responsible for the administration of such Unallocated Liability shall be entitled to reimbursement from the other Party in advance of a final determination of any Action for amounts paid in respect of costs and expenses (including allocated costs of in-house counsel and other personnel) related thereto, from time to time as such costs and expenses are incurred. In the case of any Unallocated Asset, Duke Energy shall be entitled to retain from the amount of the Unallocated Assets otherwise payable to Spectra Energy, Spectra Energy’s respective Allocated Percentage of the costs and expenses (including allocated costs of in-house counsel and other personnel) paid or incurred by or on behalf of any member of the Duke Energy Group in connection with such Unallocated Assets.

(c) Any amounts billed and properly payable in accordance with this ARTICLE VI that are not paid within 45 days of such xxxx shall bear interest at the Prime Rate plus 2% per annum.

Section 6.4. Procedures to Determine Status of Liability or Asset.

(a) On the Distribution Date, Duke Energy and Spectra Energy will form a Contingent Claim Committee of two persons and comprised of the general counsel or chief legal officer of Duke Energy and Spectra Energy (as appropriate), or their respective delegates, for the purpose of resolving whether:

(i) any Contingent Liability not identified in the schedules to this Agreement is a Power Liability, Gas Liability or Unallocated Liability; or

(ii) any Contingent Gain or Unallocated Asset not identified in the schedules to this Agreement is a Power Asset, Gas Asset or Unallocated Asset.

(b) If any Party or any member of such Party’s Group shall receive notice or otherwise learn of an Asset that may reasonably be determined to be an Unallocated Asset or Contingent Gain, or the assertion of a Third Party Claim which may reasonably be determined to be a Contingent Liability or an Unallocated Liability, not identified in the schedules to this Agreement, such Party shall give the other Party and the Contingent Claim Committee written notice thereof promptly (and in any event within fifteen (15) days) after such Person becomes aware of such Asset, Liability or Third Party Claim. Thereafter, the Party shall deliver to the Contingent Claim Committee, promptly (and in any event within five (5) Business Days) after the Party’s receipt thereof, copies of all notices and documents (including court papers) received by the Party or the member of such Party’s Group relating to the matter.

(c) The Contingent Claim Committee’s determination (which shall be made within 30 days of such referral), if unanimous, shall be binding on all of the Parties and their respective successors and assigns. In the event that the Contingent Claim Committee cannot reach a unanimous determination as to the nature or status of any such Contingent Liabilities or Contingent Gains within 30 days after such referral, the issue shall be submitted for arbitration before a single arbitrator pursuant to the procedures set forth in ARTICLE IX of this Agreement; provided, however, that no Dispute Notice or executive arbitration procedure as set forth in Section 9.1 shall be required. The outcome of the arbitration pursuant to ARTICLE IX shall be final and binding on all parties and their respective successors and assigns.

(d) In resolving, with respect to any Action not specifically addressed in this Agreement (regardless of whether such matters are currently pending but not set forth or are asserted or filed hereafter), whether

(i) any Contingent Gain is an Unallocated Asset, an Exclusive Duke Energy Contingent Gain or an Exclusive Spectra Energy Contingent Gain or

(ii) any Contingent Liability is an Unallocated Liability, an Exclusive Duke Energy Contingent Liability, or an Exclusive Spectra Energy Contingent Liability,

the categorization of Contingent Claims and Contingent Liabilities reflected in Schedules 1.1(58), 1.1(60), 1.1(69)(viii) and 1.1(112)(vi), whereby the Parties have assigned existing claims based on whether the claim or contingent liability principally relates to the Gas Business or the Power Business, shall be considered and used as a precedential guide.

(e) Duke Energy may, but shall not be obligated to, commence prosecution or defense of such matters pending decision of the Contingent Claims Committee (or decision of the arbitrator, if applicable). In the event that Duke Energy commences any such prosecution or defense and, upon resolution of the dispute, Spectra Energy is determined hereunder to have the exclusive right or obligation to such claim or right, Duke Energy shall, promptly upon the request of Spectra Energy, discontinue the prosecution or defense of such matter and transfer the control thereof to Spectra Energy. In such event, Spectra Energy will reimburse Duke Energy for all costs and expenses (including allocated costs of in-house counsel and other personnel), reasonably incurred prior to resolution of such dispute in the prosecution or defense of such claim or right.

(f) At any time or from time to time prior to the Effective Time, the chief legal officer of Duke Energy, following consultation with the designated person to be the chief legal officer of Spectra Energy, may amend or supplement any of Schedules 1.1(58), 1.1(60), 1.1(69)(viii), 1.1(112)(vi) and 1.1(146)(iii)).

Section 6.5. Certain Case Allocation Matters. The parties agree that if any Action not listed or described on Schedules 1.1(58), 1.1(60), 1.1(69)(viii), 1.1(112)(vi) or 1.1(146)(iii) involves separate and distinct claims that, if not joined in a single Action, would constitute separate Exclusive Contingent Liabilities of different Parties, they will use their commercially reasonable efforts to segregate such separate and distinct claims so that the Liabilities associated with each such claim (including all costs and expenses (including allocated costs of in-house counsel and other personnel)) shall be treated as Exclusive Contingent Liabilities of the appropriate Party and so that each Party shall have the rights and obligations with respect to each such claim (including pursuant to ARTICLE VI hereof) as would have been applicable had such claims been commenced as separate Actions. Notwithstanding the foregoing provisions, (a) all costs and expenses associated with such claims and incurred prior to the separation of the claims shall, unless otherwise provided in this Agreement, be shared in accordance with their Allocated Percentages, and (b) this Section 6.5 shall not apply to any separate and distinct claim that is de minimis or frivolous in nature.

Section 6.6. Cooperation In Defense And Settlement.

(a) With respect to any Third Party Claim that implicates both Parties in a material fashion due to the allocation of Liabilities, responsibilities for management of defense and related indemnities pursuant to this Agreement or any of the Ancillary Agreements, the Parties agree to use commercially reasonable efforts to cooperate fully and maintain a joint defense (in a manner that will preserve for both Parties the attorney-client privilege, joint defense or other privilege with respect thereto).

(b) To the extent documents, other materials, access to employees or witnesses related to or from a Party that is not responsible for the defense or liability of a

particular Action, such Party shall provide to the other Party reasonable access to documents, other materials, employees, and shall permit employees, officers and directors to cooperate as witnesses in the defense of such Action matter.

(c) Each of Duke Energy and Spectra Energy agrees that at all times from and after the Effective Time, if an Action currently exists or is commenced by a Third-Party with respect to which a Party (or any member of such Party’s respective Group) is a named defendant but such Action is otherwise not a Liability allocated to such named Party under this Agreement or any Ancillary Agreement, then the other Party shall use commercially reasonable efforts to cause the named but not liable defendant to be removed from such Action and such defendants shall not be required to make any payments or contribution in connection therewith.

(d) If, in the case of any Action involving a matter contemplated by Section 6.6(c), there is a conflict of interest between the Parties, or in the event that any Third Party Claim seeks equitable relief which would restrict or limit the future conduct of the non-responsible Party or such Party’s business or operations, such Party shall be entitled to retain, at the responsible Party’s Expense, separate counsel as required by the applicable rules of professional conduct (which counsel shall be reasonably acceptable to the responsible Party) and to participate in (but not control) the defense, compromise, or settlement of that portion of the Third Party Claim that seeks equitable relief with respect to the named Party.

ARTICLE VII

RELEASES AND INDEMNIFICATION

Section 7.1. Release of Pre-Distribution Claims.

(a) Except (i) as provided in Section 7.1(b), (ii) as may be otherwise provided in any Ancillary Agreement and (iii) for any matter for which any Party is entitled to indemnification or contribution pursuant to this ARTICLE VII, each Party, for itself and each member of its respective Group, their respective Affiliates and all Persons who at any time prior to the Effective Time were directors, officers, agents or employees of any member of their respective Group (in their respective capacities as such), in each case, together with their respective heirs, executors, administrators, successors and assigns, do hereby remise, release and forever discharge the other Party and the other members of such other Parties’ Group, their respective Affiliates and all Persons who at any time prior to the Effective Time were shareholders, directors, officers, agents or employees of any member of such other Parties (in their respective capacities as such), in each case, together with their respective heirs, executors, administrators, successors and assigns, from any and all Liabilities whatsoever, whether at Law or in equity (including any right of contribution), whether arising under any Contract, by operation of Law or otherwise, existing or arising from any acts or events occurring or failing to occur or alleged to have occurred or to have failed to occur or any conditions existing or alleged to have existed on or before the Effective Time, including in connection with all activities to implement the Distributions and any of the other transactions contemplated hereunder and under any of the Ancillary Agreements. Notwithstanding anything to the contrary in the foregoing,

nothing in this Agreement shall remise, release or discharge any rights or claims that any Party may have against any shareholder, director, officer, agent or employee of any member of such other Party’s Group (in their respective capacities as such) as a result of any unlawful or fraudulent conduct by such shareholder, director, officer, agent or employee of any member of such other Party’s Group.

(b) Nothing contained in Section 7.1(a) shall impair or otherwise affect any right of any Party, and as applicable, a member of the Party’s Group to enforce this Agreement, any Ancillary Agreement or any agreements, arrangements, commitments or understandings unrelated to the Separation and explicitly contemplated in this Agreement or any Ancillary Agreement to continue in effect after the Effective Time. In addition, nothing contained in Section 7.1(a) shall release any person from:

(i) any Liability assumed, transferred by, or assigned or allocated to, a Party or a member of such Party’s Group pursuant to or contemplated by this Agreement or any Ancillary Agreement including (A) with respect to Duke Energy, any Power Liability and (B) with respect to Spectra Energy, any Gas Liability;

(ii) any Liability for the sale, lease, construction or receipt of goods, property or services purchased, obtained or used in the ordinary course of business by a member of one Group from a member of any other Group prior to the Effective Time;

(iii) any Liability for unpaid amounts for products or services or refunds owing on products or services due on a value-received basis for work done by a member of one Group at the request or on behalf of a member of another Group;

(iv) any Liability provided in or resulting from any other Contract or understanding that is entered into after the Effective Time between any Party (and/or a member of such Party’s or Parties’ Group), on the one hand, and any other Party or Parties (and/or a member of such Party’s or Parties’ Group), on the other hand;

(v) any Liability with respect to an Unallocated Liability pursuant to ARTICLE VI; or

(vi) any Liability that the Parties may have with respect to indemnification or contribution pursuant to this Agreement or otherwise for claims brought against the Parties by a third-party, which Liability shall be governed by the provisions of this ARTICLE VII and, if applicable, the appropriate provisions of the Ancillary Agreements.

In addition, nothing contained in Section 7.1(a) shall release Duke Energy from indemnifying any director, officer or employee of Spectra Energy who was a director, officer or employee of Duke Energy or any of its Affiliates on or prior to the Effective Time, to the extent such director, officer or employee is or becomes a named defendant in any Action with respect to which he or she was entitled to such indemnification pursuant to obligations existing prior to the Effective Time, it being understood that if the underlying obligation giving rise to such Action is a Gas Liability, Spectra Energy shall indemnify Duke Energy for such Liability (including Duke

Energy’s costs to indemnify the director, officer or employee) in accordance with the provisions set forth in this ARTICLE VII.

(c) Each Party shall not, and shall not permit any member of its Group to make, any claim or demand, or commence any Action asserting any claim or demand, including any claim of contribution or indemnification, against any other Party or any member of any other Party’s Group, or any other Person released pursuant to Section 7.1(a), with respect to any and all Liabilities released pursuant to Section 7.1(a).

(d) It is the intent of each Party, by virtue of the provisions of this Section 7.1, to provide for a full and complete release and discharge of all Liabilities existing or arising from all acts and events occurring or failing to occur or alleged to have occurred or to have failed to occur and all conditions existing or alleged to have existed on or before the Effective Time, whether known or unknown, between or among any Party (and/or a member of such Party’s Group), on the one hand, and any other Party or Parties (and/or a member of such Party’s or parties’ Group), on the other hand (including any contractual agreements or arrangements existing or alleged to exist between or among any such members on or before the Effective Time), except as specifically set forth in Section 7.1(a) and 7.1(b).

(e) If any Person associated with a Party (including any director, officer or employee of a Party) initiates an Action with respect to claims released by this Section 7.1, the Party with which such Person is associated shall indemnify the other Party against such Action in accordance with the provisions set forth in this ARTICLE VII.

(f) At any time, at the request of any other Party, each Party shall cause each member of its respective Group and to the extent practicable each other Person on whose behalf it released Liabilities pursuant to this Section 7.1 to execute and deliver releases reflecting the provisions hereof.

Section 7.2. Indemnification by Duke Energy. Except as otherwise specifically set forth in any provision of this Agreement or of any Ancillary Agreement, following the Effective Time, Duke Energy shall indemnify, defend and hold harmless the Spectra Energy Indemnitees from and against any and all Indemnifiable Losses arising out of, by reason of or otherwise in connection with (i) the Power Liabilities (including, as provided in Section 1.1(112)(vii), the Exclusive Duke Energy Contingent Liabilities) or the Duke Energy Percentage of any Unallocated Liabilities, or (ii) any breach by any member of the Duke Energy Group of any provision of this Agreement or any Ancillary Agreement, unless such Ancillary Agreement expressly provides for separate indemnification therein, in which case any such indemnification claims shall be made thereunder.

Section 7.3. Indemnification by Spectra Energy. Except as otherwise specifically set forth in any provision of this Agreement or of any Ancillary Agreement, Spectra Energy shall indemnify, defend and hold harmless the Duke Energy Indemnitees from and against any and all Indemnifiable Losses arising out of, by reason of or otherwise in connection with (i) the Gas Liabilities (including, as provided in Section 1.1(69)(vi), the Exclusive Spectra Energy Contingent Liabilities) or the Spectra Energy Percentage of any Unallocated Liabilities, or (ii) any breach by Spectra Energy or any member of the Spectra Energy Group of any provision of

this Agreement or any Ancillary Agreement, unless such Ancillary Agreement expressly provides for separate indemnification therein, in which case any such indemnification claims shall be made thereunder.

Section 7.4. Procedures for Indemnification.

(a) An Indemnitee shall give the Indemnifying Party notice of any matter that an Indemnitee has determined has given or could give rise to a right of indemnification under this Agreement (other than a Third Party Claim which shall be governed by Section 7.4(b)), within ten (10) Business Days of such determination, stating the amount of the Loss claimed, if known, and method of computation thereof, and containing a reference to the provisions of this Agreement in respect of which such right of indemnification is claimed by such Indemnitee or arises; provided, however, that the failure to provide such notice shall not release the Indemnifying Party from any of its obligations except and solely to the extent the Indemnifying Party shall have been materially prejudiced as a result of such failure (except that the Indemnifying Party or Parties shall not be liable for any expenses incurred during the period in which the Indemnitee failed to give such notice).

(b) Third Party Claims. If a claim or demand is made against a Duke Energy Indemnitee or a Spectra Energy Indemnitee (each, an “Indemnitee”) by any Person who is not a party to this Agreement or an Affiliate of a Party (a “Third Party Claim”) as to which such Indemnitee is or may be entitled to indemnification pursuant to this Agreement, such Indemnitee shall notify the Party which is or may be required pursuant to this ARTICLE VII or pursuant to any Ancillary Agreement to make such indemnification (the “Indemnifying Party”) in writing, and in reasonable detail, of the Third Party Claim promptly (and in any event within fifteen (15) days) after receipt by such Indemnitee of written notice of the Third Party Claim; provided, however, that the failure to provide notice of any such Third Party Claim pursuant to this sentence shall not release the Indemnifying Party from any of its obligations except and solely to the extent the Indemnifying Party shall have been materially prejudiced as a result of such failure (except that the Indemnifying Party or Parties shall not be liable for any expenses incurred during the period in which the Indemnitee failed to give such notice). Thereafter, the Indemnitee shall deliver to the Indemnifying Party, promptly (and in any event within ten (10) Business Days) after the Indemnitee’s receipt thereof, copies of all notices and documents (including court papers) received by the Indemnitee relating to the Third Party Claim.

(c) Other than in the case of an Unallocated Liability (the defense of which shall be controlled as provided for in ARTICLE VI) or any Liability being managed by a Party in accordance with any Ancillary Agreement, an Indemnifying Party shall be entitled (but shall not be required) to assume, control the defense of, and settle any Third Party Claim, at such Indemnifying Party’s own cost and expense and by such Indemnifying Party’s own counsel, that is reasonably acceptable to the applicable Indemnitees, if it gives notice of its intention to do so to the applicable Indemnitees within thirty (30) days of the receipt of such notice from such Indemnitees. After notice from an Indemnifying Party to an Indemnitee of its election to assume the defense of a Third Party Claim, such Indemnitee shall have the right to employ separate counsel and to participate in (but not control) the defense, compromise, or settlement thereof, at its own expense and, in any event, shall cooperate with the Indemnifying Party in such defense and make available to the Indemnifying Party all witnesses, pertinent Information, materials and

information in such Indemnitee’s possession or under such Indemnitee’s control relating thereto as are reasonably required by the Indemnifying Party. In the event of a conflict of interest between the Indemnifying Party and the applicable Indemnitee(s), or in the event that any Third Party Claim seeks equitable relief which would restrict or limit the future conduct of the Indemnitee(s) business or operations, such Indemnitee(s) shall be entitled to retain, at the Indemnifying Party’s Expense, separate counsel as required by the applicable rules of professional conduct (which counsel shall be reasonably acceptable to the Indemnifying Party) and to participate in (but not control) the defense, compromise, or settlement of that portion of the Third Party Claim that seeks equitable relief with respect to the Indemnitee(s).

(d) Other than in the case of an Unallocated Liability, if an Indemnifying Party elects not to assume responsibility for defending a Third Party Claim, or fails to notify an Indemnitee of its election as provided in Section 7.4(c), such Indemnitee may defend such Third Party Claim at the cost and expense of the Indemnifying Party. If the Indemnitee is conducting the defense against any such Third Party Claim, the Indemnifying Party shall cooperate with the Indemnitee in such defense and make available to the Indemnitee all witnesses, pertinent Information, material and information in such Indemnifying Party’s possession or under such Indemnifying Party’s control relating thereto as are reasonably required by the Indemnitee.

(e) Unless the Indemnifying Party has failed to assume the defense of the Third Party Claim in accordance with the terms of this Agreement, no Indemnitee may settle or compromise any Third Party Claim that is not an Unallocated Liability (which shall be governed by Section 6.4) without the consent of the Indemnifying Party, which consent shall not be unreasonably withheld or delayed. If an Indemnifying Party has failed to assume the defense of the Third Party Claim, it shall not be a defense to any obligation to pay any amount in respect of such Third Party Claim that the Indemnifying Party was not consulted in the defense thereof, that such Indemnifying Party’s views or opinions as to the conduct of such defense were not accepted or adopted, that such Indemnifying Party does not approve of the quality or manner of the defense thereof or that such Third Party Claim was incurred by reason of a settlement rather than by a judgment or other determination of liability.

(f) In the case of a Third Party Claim (except for any Third Party Claim that is an Unallocated Liability which, with respect to the subject matter of this Section 7.4(f), shall be governed by Section 6.4), no Indemnifying Party shall consent to entry of any judgment or enter into any settlement of the Third Party Claim without the consent (not to be unreasonably withheld) of the Indemnitee if the effect thereof is to permit any injunction, declaratory judgment, other order or other nonmonetary relief to be entered, directly or indirectly, against any Indemnitee; it being understood that in the case of a Third Party Claim that is an Unallocated Liability, such matters are addressed in ARTICLE VI.

(g) Except as otherwise provided in Section 11.21, absent fraud or willful misconduct by an Indemnifying Party, the indemnification provisions of this ARTICLE VII shall be the sole and exclusive remedy of an Indemnitee for any monetary or compensatory damages or losses resulting from any breach of this Agreement (including with respect to monetary or compensatory damages or losses arising out of or relating to, as the case may be, any Gas Liability or Power Liability), and each Indemnitee expressly waives and relinquishes any and all

rights, claims or remedies such Person may have with respect to the foregoing other than under this ARTICLE VII against any Indemnifying Party.

Section 7.5. Indemnification Payments. Indemnification required by this ARTICLE VII shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or an Indemnifiable Loss or Liability incurred.

Section 7.6. Indemnification Obligations Net of Insurance Proceeds and Other Amounts on a Net-Tax Basis.

(a) Any Liability subject to indemnification or contribution pursuant to this ARTICLE VII, including in respect of any Unallocated Liability, will (i) be net of Insurance Proceeds that actually reduce the amount of the Liability, (ii) be net of any proceeds received by the Indemnitee from any third party for indemnification for such Liability that actually reduce the amount of the Liability (“Third Party Proceeds”) and (iii) will be determined on a Net-Tax Basis. Accordingly, the amount which any Indemnifying Party is required to pay pursuant to this ARTICLE VII to any Indemnitee pursuant to this ARTICLE VII will be reduced by any Insurance Proceeds or Third Party Proceeds theretofore actually recovered by or on behalf of the Indemnitee in respect of the related Liability. If an Indemnitee receives a payment required by this Agreement from an Indemnifying Party in respect of any Liability (an “Indemnity Payment”) and subsequently receives Insurance Proceeds or Third Party Proceeds, then the Indemnitee will pay to the Indemnifying Party an amount equal to the excess of the Indemnity Payment received over the amount of the Indemnity Payment that would have been due if the Insurance Proceeds or Third Party Proceeds had been received, realized or recovered before the Indemnity Payment was made.

(b) An insurer who would otherwise be obligated to pay any claim shall not be relieved of the responsibility with respect thereto or, solely by virtue of the indemnification and contributions provisions hereof, have any subrogation rights with respect thereto. The Indemnitee shall use commercially reasonable efforts to seek to collect or recover any third-party Insurance Proceeds and any Third Party Proceeds to which the Indemnified Party is entitled in connection with any Liability for which the Indemnified Party seeks contribution or indemnification pursuant to this ARTICLE VII; provided, that the Indemnitee’s inability to collect or recover any such Insurance Proceeds or Third Party Proceeds shall not limit the Indemnifying Party’s obligations hereunder.

(c) The term “Net-Tax Basis” as used in this ARTICLE VII means that, in determining the amount of the payment necessary to indemnify any party against, or reimburse any party for, Liabilities, the amount of such Liabilities will be determined net of any theoretical reduction in Tax realizable (assuming a hypothetical effective tax rate of 40%) by the Indemnitee as the result of sustaining or paying such Liabilities after taking into account any Tax incurred on the receipt of Insurance Proceeds, and the amount of such Indemnity Payment will be increased (i.e., “grossed up”) by the amount necessary to satisfy any income or franchise Tax liabilities that will be incurred by the Indemnitee as a result of its receipt of, or right to receive, such Indemnity Payment (as so increased), so that the Indemnitee is put in the same net after-Tax economic

position as if it had not incurred such Liabilities, in each case without taking into account any impact on the Tax basis that an Indemnitee has in its assets.

Section 7.7. Additional Matters; Survival of Indemnities.

(a) The indemnity and contribution agreements contained in this ARTICLE VII shall remain operative and in full force and effect, regardless of (i) any investigation made by or on behalf of any Indemnitee; and (ii) the knowledge by the Indemnitee of Liabilities for which it might be entitled to indemnification or contribution hereunder.

(b) The rights and obligations of each Party and their respective Indemnitees under this ARTICLE VII shall survive the sale or other transfer by any Party or its respective Subsidiaries of any Assets or businesses or the assignment by it of any and all Liabilities.

ARTICLE VIII

CONFIDENTIALITY; ACCESS TO INFORMATION

Agreement or any Ancillary Agreement. Notwithstanding the foregoing, in the event that any demand or request for disclosure of Confidential Information is made pursuant to clause (ii) above, each Party, as applicable, shall promptly notify the other of the existence of such request or demand and shall provide the other a reasonable opportunity to seek an appropriate protective order or other remedy, which such Parties will cooperate in obtaining. In the event that such appropriate protective order or other remedy is not obtained, the Party whose Confidential Information is required to be disclosed shall or shall cause the other applicable Party or Parties to furnish, or cause to be furnished, only that portion of the Confidential Information that is legally required to be disclosed and shall take commercially reasonable steps to ensure that confidential treatment is accorded such information.

(b) Notwithstanding anything to the contrary set forth herein, (i) the Parties shall be deemed to have satisfied their obligations hereunder with respect to Confidential Information if they exercise the same degree of care (but no less than a reasonable degree of care) as they take to preserve confidentiality for their own similar information and (ii) confidentiality obligations provided for in any agreement between each Party or its Subsidiaries and their respective employees shall remain in full force and effect. Notwithstanding anything to the contrary set forth herein, Confidential Information of any Party in the possession of and used by any other Party as of the Effective Time may continue to be used by such Party in possession of the Confidential Information in and only in the operation of the Gas Business or the Power Business, as the case may be; provided, such Confidential Information may be used only so long as the Confidential Information is maintained in confidence and not disclosed in violation of Section 8.4(a). Such continued right to use may not be transferred (directly or indirectly) to any third party without the prior written consent of the applicable Party, except pursuant to Section 11.9.

(c) Each Party acknowledges that it and the other members of its Group may have in their possession confidential or proprietary information of third parties that was received under confidentiality or non-disclosure agreements with such third party prior to the Effective Time. Such Party will hold, and will cause the other members of its Group and their respective representatives to hold, in strict confidence the confidential and proprietary information of third parties to which they or any other member of their respective Groups has access, in accordance with the terms of any agreements entered into prior to the Effective Time between one or more members of the such Party’s Group (whether acting through, on behalf of, or in connection with, the separated Businesses) and such third parties.

(d) Upon the written request of a Party, the other Party shall promptly, (i) deliver to such requesting Party all original Confidential Information (whether written or electronic) concerning such requesting Party and/or its Subsidiaries, and (ii) if specifically requested by such requesting Party, destroy any copies of such Confidential Information (including any extracts there from). Upon the written request of such requesting Party, the other Party shall cause one of its duly authorized officers to certify in writing to such requesting Party that the requirements of the preceding sentence have been satisfied in full.

Section 8.5. Privileged Matters.

(a) Pre-Separation Services. The Parties recognize that legal and other professional services that have been and will be provided prior to the Effective Time have been and will be rendered for the collective benefit of each of the members of the Duke Energy Group and the Spectra Energy Group, and that each of the members of the Duke Energy Group and the Spectra Energy Group should be deemed to be the client with respect to such pre-separation services for the purposes of asserting all privileges which may be asserted under applicable Law.

(b) Post-Separation Services. The Parties recognize that legal and other professional services will be provided following the Effective Time which will be rendered solely for the benefit of Duke Energy or Spectra Energy, as the case may be. With respect to such post-separation services, the Parties agrees as follows:

(i) Duke Energy shall be entitled, in perpetuity, to control the assertion or waiver of all privileges in connection with privileged information which relates solely to the Power Business, whether or not the privileged information is in the possession of or under the control of Duke Energy or Spectra Energy. Duke Energy shall also be entitled, in perpetuity, to control the assertion or waiver of all privileges in connection with privileged information that relates solely to the subject matter of any claims constituting Power Liabilities, now pending or which may be asserted in the future, in any lawsuits or other proceedings initiated against or by Duke Energy, whether or not the privileged information is in the possession of or under the control of Duke Energy or Spectra Energy; and

(ii) Spectra Energy shall be entitled, in perpetuity, to control the assertion or waiver of all privileges in connection with privileged information which relates solely to the Gas Business, whether or not the privileged information is in the possession of or under the control of Duke Energy or Spectra Energy. Spectra Energy shall also be entitled, in perpetuity, to control the assertion or waiver of all privileges in connection with privileged information that relates solely to the subject matter of any claims constituting Gas Liabilities, now pending or which may be asserted in the future, in any lawsuits or other proceedings initiated against or by Spectra Energy, whether or not the privileged information is in the possession of or under the control of Duke Energy or Spectra Energy.

(c) The Parties agree that they shall have a shared privilege, with equal right to assert or waive, subject to the restrictions in this Section 8.5, with respect to all privileges not allocated pursuant to the terms of Section 8.5(b). All privileges relating to any claims, proceedings, litigation, disputes, or other matters which involve both Duke Energy and Spectra Energy in respect of which both Parties retain any responsibility or Liability under this Agreement, shall be subject to a shared privilege among them.

(d) No Party may waive any privilege which could be asserted under any applicable Law, and in which any other Party has a shared privilege, without the consent of the other Party, which shall not be unreasonably withheld or delayed or as provided in subsections (e) or (f) below. Consent shall be in writing, or shall be deemed to be granted unless written

objection is made within twenty (20) days after notice upon the other Party requesting such consent.

(e) In the event of any litigation or dispute between or among any of the Parties, or any members of their respective Groups, either such Party may waive a privilege in which the other Party or member of such Group has a shared privilege, without obtaining the consent of the other Party; provided, that such waiver of a shared privilege shall be effective only as to the use of information with respect to the litigation or dispute between the relevant Parties and/or the applicable members of their respective Group’s, and shall not operate as a waiver of the shared privilege with respect to third parties.

(f) If a dispute arises between or among the Parties or their respective Subsidiaries regarding whether a privilege should be waived to protect or advance the interest of any Party, each Party agrees that it shall negotiate in good faith, shall endeavor to minimize any prejudice to the rights of the other Parties, and shall not unreasonably withhold consent to any request for waiver by another Party. Each Party specifically agrees that it will not withhold consent to waiver for any purpose except to protect its own legitimate interests.

(g) Upon receipt by any Party or by any Subsidiary thereof of any subpoena, discovery or other request which arguably calls for the production or disclosure of information subject to a shared privilege or as to which another Party has the sole right hereunder to assert a privilege, or if any Party obtains knowledge that any of its or any of its Subsidiaries’ current or former directors, officers, agents or employees have received any subpoena, discovery or other requests which arguably calls for the production or disclosure of such privileged information, such Party shall promptly notify the other Party or Parties of the existence of the request and shall provide the other Party or Parties a reasonable opportunity to review the information and to assert any rights it or they may have under this Section 8.5 or otherwise to prevent the production or disclosure of such privileged information.

(h) The transfer of all Information pursuant to this Agreement is made in reliance on the agreement of Duke Energy and Spectra Energy as set forth in Section 8.4 and Section 8.5, to maintain the confidentiality of privileged information and to assert and maintain all applicable privileges. The access to information being granted pursuant to Section 6.6, Section 8.1 and Section 8.2 hereof, the agreement to provide witnesses and individuals pursuant to Section 6.6 and Section 8.3 hereof, the furnishing of notices and documents and other cooperative efforts contemplated by Section 6.6 and Section 8.5 hereof, and the transfer of privileged information between and among the Parties and their respective Subsidiaries pursuant to this Agreement shall not be deemed a waiver of any privilege that has been or may be asserted under this Agreement or otherwise.

Section 8.6. Ownership of Information. Any information owned by one Party or any of its Subsidiaries that is provided to a requesting Party pursuant to this ARTICLE VIII shall be deemed to remain the property of the providing Party. Unless specifically set forth herein, nothing contained in this Agreement shall be construed as granting or conferring rights of license or otherwise in any such information.

Section 8.7. Other Agreements. The rights and obligations granted under this ARTICLE VIII are subject to any specific limitations, qualifications or additional provisions on the sharing, exchange or confidential treatment of information set forth in any Ancillary Agreement.

ARTICLE IX

DISPUTE RESOLUTION

Section 9.1. Negotiation.

(a) Except as specifically provided in Section 6.4, in the event of a controversy, dispute or claim arising out of, in connection with, or in relation to the interpretation, performance, nonperformance, validity, termination or breach of this Agreement or otherwise arising out of, or in any way related to this Agreement or the transactions contemplated hereby, including any claim based on contract, tort, statute or constitution (but excluding any controversy, dispute or claim arising out of any Contract relating to the use or lease of real property if any third party is a necessary party to such controversy, dispute or claim) (collectively, “Agreement Disputes”), the general counsel or chief legal officer (as appropriate) of the relevant Parties (or such other executive officer designated by the relevant Party) shall negotiate for a reasonable period of time to settle such Agreement Dispute; provided, that (i) such reasonable period shall not, unless otherwise agreed by the relevant Parties in writing, exceed fifteen (15) days from the time of receipt by a Party of written notice of such Agreement Dispute (“Dispute Notice”) and (ii) the relevant employees from both Parties with knowledge and interest in the dispute shall first have tried to resolve the differences between the Parties. Within twenty-three (23) days of receipt of the Dispute Notice, the receiving Party shall submit to the other Party a written response. The Dispute Notice and the response shall each include a statement of the Party’s position, a general summary of the arguments supporting that position, the name and title of the executive who will represent the party and any other person(s) who will attend settlement meetings. If the aggregate amount in controversy, dispute or claim (or any series of related controversies, disputes or claims), as set forth in the Dispute Notice and the applicable response, is less than $100,000, the Parties agree that such controversy, dispute or claim shall not be submitted to Arbitration pursuant to Section 9.2 and that the Party who shall have submitted the Dispute Notice shall have no further recourse under this ARTICLE IX or under any applicable Law.

(b) In the event of any Agreement Dispute with respect to which a Dispute Notice has been delivered in accordance with this Section 9.1, and if arbitration proceedings are initiated pursuant to Section 9.2 within 180 days following receipt of the Dispute Notice, (i) the relevant Parties shall not assert the defenses of statute of limitations and laches with respect to the period beginning after the date of receipt of the Dispute Notice, and (ii) any contractual time period or deadline under this Agreement or any Ancillary Agreement to which such Agreement Dispute relates occurring after the Dispute Notice is received shall not be deemed to have passed until such Agreement Dispute has been resolved. Nothing said or disclosed, nor any document produced, in the course of any negotiations, conferences and discussions in connection with efforts to settle an Agreement Dispute that is not otherwise independently discoverable shall be

offered or received as evidence or used for impeachment or for any other purpose in any arbitration, but shall be considered as to have been disclosed for settlement purposes.

Section 9.2. Arbitration. If the Agreement Dispute has not been resolved for any reason after fifteen (15) days have elapsed from the receipt by a Party of a Dispute Notice, such Agreement Dispute shall be exclusively and finally determined, at the request of any relevant Party, by arbitration conducted where the Parties agree it would be most convenient, and in the absence of agreement in New York City, before and in accordance with the CPR Rules for Non-Administered Arbitration then currently in effect, except as modified herein (the “Rules”).

Section 9.3. Selection of Arbitrator(s). In the event that any Party’s claim or counterclaims equals or exceed $3 million (except for any claim or counterclaims pursuant to Section 6.4), exclusive of interest or attorneys’ fees, the Agreement Dispute shall be heard and determined by three (3) arbitrators; otherwise, the Agreement Dispute shall be heard and determined by one (1) arbitrator. In the event that one arbitrator shall hear the Agreement Dispute, the Parties shall attempt to agree upon a qualified individual to serve as arbitrator. If the Parties are unable to agree on an arbitrator within 30 days of the receipt by respondent of a copy of the demand for arbitration, then the arbitrator shall be selected and appointed by the International Institute for Conflict Prevention & Resolution (“CPR”) in accordance with the listing and ranking method in the Rules, and in any such procedure, each party shall be given a limited number of strikes, excluding strikes for cause. In the event that three arbitrators shall hear the Agreement Dispute, and if there are only two Parties to the arbitration, each Party shall appoint its arbitrator within twenty (20) days of receipt by respondent of a copy of the demand for arbitration. The two party-appointed arbitrators shall have twenty (20) days from the appointment of the second arbitrator to agree on a third arbitrator who shall chair the arbitral tribunal. Any arbitrator not timely appointed by the Parties shall be appointed by the CPR in accordance with the listing and ranking method in the Rules, and in any such procedure, each party shall be given a limited number of strikes, excluding strikes for cause. If any appointed arbitrator declines, resigns, becomes incapacitated, or otherwise refuses or fails to serve or to continue to serve as an arbitrator, the Party or arbitrators entitled to appoint such arbitrator shall promptly appoint a successor. In the event that an arbitrator is objected to, CPR shall decide whether such objection is valid and whether the challenged arbitrator shall be removed. Any controversy concerning the jurisdiction of the arbitrator(s), whether an Agreement Dispute is arbitrable, whether arbitration has been waived, whether an assignee of this Agreement is bound to arbitrate, or as to the interpretation of enforceability of this ARTICLE IX shall be determined by the arbitrator(s).

Section 9.4. Arbitration Procedures. The arbitrator(s) shall attempt to resolve the disputed based on pleadings, sworn statements and other written materials without the need for live hearings. In the event the arbitrator(s) determine that oral argument is beneficial to the arbitrator(s) understanding of the issues, oral argument may be conducted. In the event the arbitrator(s) determine that live hearings are necessary for the proper resolution of the dispute, a hearing shall be conducted. Any oral argument to be conducted shall be held no later than 150 days following appointment of the arbitrator(s). Any hearing to be conducted shall be held no later than 180 days following appointment of the arbitrator(s).

Section 9.5. Discovery. The arbitrator(s), consistent with the expedited nature of arbitration, shall permit discovery only if there is clear and convincing evidence that discovery is necessary. If the arbitrator(s) so determine, they may permit limited document discovery and no more than three depositions per party of no more than 8 hours each. Notwithstanding the foregoing, each Party will, upon the written request of the other Party, promptly provide the other with copies of documents on which the producing Party may rely in support of a claim or defense or which are relevant to the issues raised in the Agreement Dispute. All discovery, if any, shall be completed within 90 days following the appointment of the arbitrator(s). Adherence to formal rules of evidence shall not be required and the arbitrator(s) shall consider any evidence and testimony that the arbitrator(s) determine to be relevant, in accordance with the Rules and procedures that the arbitrator(s) determine to be appropriate. In resolving any Agreement Dispute, the Parties intend that the arbitrator(s) shall apply the substantive Laws of the State of New York, without regard to any choice of law principles thereof that would mandate the application of the laws of another jurisdiction. The Parties intend that the provisions to arbitrate set forth herein be valid, enforceable and irrevocable, and any award rendered by the arbitrator(s) shall be final and binding on the Parties. The Parties agree to comply and cause the members of their applicable Group to comply with any award made in any such arbitration proceedings and agree to enforcement of or entry of judgment upon such award, in any court of competent jurisdiction.

Section 9.6. Confidentiality of Proceedings. Without limiting the provisions of the Rules, unless otherwise agreed in writing by or among the relevant Parties or permitted by this Agreement, the relevant Parties shall keep, and shall cause the members of their applicable Group to keep, confidential all matters relating to the arbitration or the award. All negotiations, conferences and discussions pursuant to this ARTICLE IX shall be treated as compromise and settlement negotiations; provided, that such matters may be disclosed (i) to the extent reasonably necessary in any proceeding brought to enforce this agreement to arbitrate or any arbitral award or for entry of a judgment upon the award and (ii) to the extent otherwise required by Law or regulatory authority.

Section 9.7. Pre-Hearing Procedure and Disposition. Nothing contained herein is intended to or shall be construed to prevent any Party, from applying to any court of competent jurisdiction for interim measures or other provisional relief in connection with the subject matter of any Agreement Disputes, including to compel a party to arbitrate any Agreement Dispute or to require witnesses to obey subpoenas issued by the arbitrator(s). Without prejudice to such provisional remedies as may be available under the jurisdiction of a court, the arbitral tribunal shall have full authority to grant provisional remedies and to direct the parties to request that any court modify or vacate any temporary or preliminary relief issued by such court, and to award damages for the failure of any party to respect the arbitral tribunal’s orders to that effect. The Parties agree to accept and honor any orders relating to interim or provisional remedies that are issued by the arbitrator(s) and agree that any such interim order or remedy may be enforced, as necessary, in any court of competent jurisdiction.

Section 9.8. Continuity of Service and Performance. During the course of dispute resolution pursuant to the provisions of this ARTICLE IX, the Parties will continue to provide all other services and honor all other commitments under this Agreement and each Ancillary Agreement with respect to all matters not subject to such dispute resolution.

Section 9.9. Awards. The arbitrator(s) shall make an award and issue a reasoned opinion in writing setting forth the basis for such award within 30 days following the submission of all written materials in support of and in opposition to any claim, or if there is a hearing, within 30 days of such hearing. The arbitrator(s) shall be entitled, if appropriate, to award any remedy in such proceedings that is permitted under this Agreement and applicable law, including monetary damages, specific performance and other forms of legal and equitable relief. The Parties hereby waive any claim to exemplary, punitive, multiple or similar damages in excess of compensatory damages, attorneys’ fees, costs and expenses of arbitration, except as may be expressly required by statute or as necessary to indemnify a Party for a Third Party Claim and the arbitrator(s) are not empowered to and shall not award such damages. Any final award must provide that the party against whom an award is issued shall comply with the order within a specified period of time, not to exceed 30 days.

Section 9.10. Costs. If any Party attempts, unsuccessfully, to prevent an Arbitration Dispute from being arbitrated such Party shall reimburse the prevailing party for all costs incurred in compelling arbitration. Except as otherwise may be provided in this Agreement or in any Ancillary Agreement, the arbitrator(s) may apportion the costs of arbitration between or among the Parties in such a manner as the arbitrator deem reasonable, taking into account the facts and circumstances of the case.

Section 9.11. Adherence to Time Limits. In accepting appointment, an arbitrator shall commit that his or her schedule permits him or her to devote the reasonably necessary time and attention to the arbitration proceedings and to resolving the Agreement Dispute within the time periods set by this Agreement and by the Rules. Any time limits set out in this ARTICLE IX or in the Rules may be modified upon written agreement of the parties and the arbitrator(s) or by order of the arbitrator(s) for good cause shown. Any failure of the arbitrator(s) to comply with such time limits or to render a final award within the time specified shall not impair the validity of the award or cause the award to be void or voidable, nor shall it be a basis for challenge of the validity or enforceability of the award or of the arbitration proceedings.

Section 9.12. Limitation on Actions. Limitation on Actions. Notwithstanding anything to the contrary in this Agreement, (a) no Action shall be commenced (including the dispute resolution procedures set forth in this Article IX) by an Indemnitee against an Indemnifying Party or any of their respective Affiliates more than 12 months after the Indemnitee acquires, or reasonably should have acquired, knowledge of the facts giving rise to its right to indemnification under Article VII (it being understood that if no such Action is commenced within such 12-month period, the Indemnifying Party shall be discharged from liability for such claim); and (b) no Action shall be commenced (including the dispute resolution procedures set forth in this Article IX) by a Party against the other Party asserting any claim arising from breach of any obligation of such other Party under this Agreement more than 12 months after such first Party acquires, or reasonably should have acquired, knowledge of such breach, provided, however, regardless of such first Party’s knowledge of the facts giving rise to its claim based on a breach of this Agreement, no Action shall be commenced by such first Party against the other Party more than 36 months after the occurrence of the initial event giving rise to such claim for such breach (it being understood that if no such Action is commenced within such 12-month or 36-month periods, as applicable, the breaching Party shall be discharged from liability for such breach).

(c) With respect to all claims that arise out of occurrences that occur prior to the Effective Time and for which coverage is available under any Third Party Shared Policies pursuant to paragraphs (a) or (b) of this Section 10.3, Spectra Energy or the relevant member of the Spectra Energy Group shall be responsible for bearing the full amount of the deductible and/or any claims, costs and expenses that are not covered under the relevant Captive Gas Policy or such Third Party Shared Policies. Duke Energy will cause the captive insurance company that issued the relevant Captive Gas Policy to be responsible for bearing the full amount of the deductible and/or any claims, costs and expenses that are not covered under such Third Party Shared Policies only to the extent they are covered by the relevant Captive Gas Policy.

(d) With respect to all Third Party Shared Policies, Spectra Energy agrees and covenants (on behalf of itself and each other member of the Spectra Energy Group, and each other Affiliate of Spectra Energy) not to make any claim or assert any rights against Duke Energy and any other member of the Duke Energy Group (including the captive insurance companies that are insured under the Third Party Shared Policies), or the unaffiliated third-party insurers of such Third Party Shared Policies, except as expressly provided under this Section 10.3.

Section 10.4. Administration of Third Party Shared Policies; Other Matters.

(a) For the avoidance of doubt, from and after the Effective Time, (i) Spectra Energy or a member of the Spectra Energy Group shall be responsible for the administration of all Third Party Gas Policies and Captive Gas Policies, and (ii) Duke Energy or a member of the Duke Energy Group shall be responsible for the administration of all Third Party Power Policies and Captive Power Policies; provided, with respect to any Captive Gas Policies issued by Bison Insurance Company Limited, Duke Energy shall cause Bison Insurance Company Limited to administer such policies to the extent it is required to perform under the Captive Gas Policies.

(b) With respect to all Third Party Shared Policies, from and after the Effective Time, Duke Energy or a member of the Duke Energy Group (including the captive insurance companies that are insured under the Third Party Shared Policies) shall be responsible for the Insurance Administration and Claims Administration of such Third Party Shared Policies; provided, that the retention of such administrative responsibilities by Duke Energy or a member of the Duke Energy Group is in no way intended to limit, inhibit or preclude any right to insurance coverage for any Insured Claim of a named insured under such Third Party Shared Policies as contemplated by the terms of this Agreement; provided, further, that the retention of such administrative responsibilities by Duke Energy or a member of the Duke Energy Group shall not relieve the Person submitting any Insured Claim of the primary responsibility for reporting such Insured Claim accurately, completely and in a timely manner, or of such Person’s authority to settle any such Insured Claim within any period permitted or required by the relevant Third Party Shared Policy. At its discretion, and in accordance with the terms of the Third Party Shared Policies, Duke Energy may discharge its administrative responsibilities with respect to such Third Party Shared Policies by contracting for the provision of administrative services to any unaffiliated Person, including, after the Effective Time, Spectra Energy or any of its Affiliates. Spectra Energy shall reimburse Duke Energy for any costs incurred by Duke Energy related to such Insurance Administration and Claims Administration to the extent such costs (which include defense, out-of-pocket expenses, and direct and indirect costs of employees or agents of Duke Energy providing the administrative services) are (i) not covered under the Third Party Shared Policies and (ii) related to Gas Liabilities or Spectra Energy’s proportionate share of the Unallocated Liabilities. Duke Energy or any member of the Duke Energy Group shall not settle any Insured Claim of Spectra Energy or any member of Spectra Energy Group under the Third Party Shared Policies without first obtaining the approval of Spectra Energy or such member of Spectra Energy Group. Such approval shall not be unreasonably withheld, delayed or conditioned.

(c) Exceeding Policy Limits. Where Gas Liabilities are specifically covered under a Third Party Shared Policy for periods prior to the Effective Time, or where such Third Party Shared Policy covers claims made after the Effective Time with respect to an occurrence prior to the Effective Time, then from and after the Effective Time, Spectra Energy may claim coverage for Insured Claims under such Third Party Shared Policy as and to the extent that such insurance is available up to the full extent of the applicable limits of liability of such Third Party Shared Policy (and may receive any Insurance Proceeds with respect thereto as contemplated by Section 10.3 or Section 10.4(e)), subject to the terms of this Section 10.4. It is expressly understood that so long as Duke Energy is an Affiliate of Spectra Energy prior to the Effective Time, Duke Energy may claim such coverage on behalf of Spectra Energy.

(d) Claims Not Reimbursed. Except as set forth in this Section 10.4, Duke Energy and Spectra Energy shall not be liable to one another (nor shall any member of the Duke Energy Group be liable to any member of the Spectra Energy Group) for claims, or portions of claims, not reimbursed by insurers under any Third Party Shared Policy for any reason not within the control of Duke Energy or Spectra Energy, including coinsurance provisions, deductibles, quota share deductibles, self-insured retentions, bankruptcy or insolvency of any insurance carrier(s), Third Party Shared Policy limitations or restrictions, any coverage disputes, any failure to timely file a claim by Duke Energy or Spectra Energy (or any of the members of their respective Groups), or any defect in such claim or its processing. The liability of Duke Energy and Spectra Energy to one another for such claims is expressly limited to the amount of Insurance Proceeds received with respect to such claims and allocated to the respective Parties in accordance with Section 10.4(e). It is expressly understood that the foregoing provisions in this Section 10.4(d) shall not limit any Party’s liability to any other Party for indemnification pursuant to ARTICLE VII.

(e) Allocation of Insurance Proceeds. Except as otherwise provided in Section 10.3, Insurance Proceeds received with respect to claims, costs and expenses under the Third Party Shared Policies which are issued to any Captive Insurer shall be paid to or on behalf of the Captive Insurer that is the insured under the relevant Third Party Shared Policy, which Captive Insurer shall thereafter administer the Third Party Shared Policies by paying the Insurance Proceeds, as appropriate, to Duke Energy with respect to Power Liabilities covered by any Captive Power Policy and Spectra Energy with respect to Gas Liabilities covered by any Captive Gas Policy. Payments of Insurance Proceeds to such Captive Insurer with respect to any Unallocated Liability covered by either a Captive Power Policy or a Captive Gas Policy, as the case may be, shall be paid by such Captive Insurer to the Parties in accordance with their respective Allocated Percentage. In the event that the aggregate limits on any Third Party Shared Policies (except in the case of any Unallocated Liability which is covered in the preceding sentence) are exceeded by the aggregate of outstanding Insured Claims by the Parties or members of their respective Groups, the Parties agree to allocate the Insurance Proceeds received thereunder based upon their respective percentage of the total of their bona fide claims which were covered under such Third Party Shared Policy, and any Party who has received Insurance Proceeds in excess of such Party’s respective percentage of Insurance Proceeds shall pay to the other Party the appropriate amount so that each Party will have received its respective percentage of Insurance Proceeds pursuant hereto. Each of the Parties agrees to use commercially reasonable efforts to maximize available coverage under those Third Party Shared Policies applicable to it, and to take all commercially reasonable steps to recover from all other responsible parties in respect of an Insured Claim to the extent coverage limits under a Third Party Shared Policy have been exceeded or would be exceeded as a result of such Insured Claim.

(f) Allocation of Deductibles. In the event that the Parties or members of their respective Groups have bona fide claims under any Third Party Shared Policy arising from the same occurrence and for which a deductible is payable, the Parties agree that the aggregate amount of the deductible paid shall be borne by the Parties in the same proportion which the Insurance Proceeds received by each such Party bears to the total Insurance Proceeds received under the applicable Third Party Shared Policy pursuant to Section 10.4(e), and any Party who has paid more than such allocable share of the deductible shall be entitled to receive from the

other Party an appropriate amount so that each Party has borne its allocable share of the deductible pursuant hereto.

Section 10.5. Agreement for Waiver of Conflict and Shared Defense. In the event that Insured Claims of more than one of the Parties exist relating to the same occurrence, the Parties shall jointly defend and waive any conflict of interest necessary to the conduct of the joint defense. Nothing in this ARTICLE X shall be construed to limit or otherwise alter in any way the obligations of the Parties, including those created by this Agreement, by operation of Law or otherwise.

Section 10.6. Cooperation. The Parties agree to use (and cause the members in their respective Groups to use) their commercially reasonable efforts to cooperate with respect to the various insurance matters contemplated by this ARTICLE X.

Section 10.7. Certain Matters Relating to Duke Energy’s Organizational Documents. For a period of six (6) years from the Effective Time, the Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws of Duke Energy shall contain provisions no less favorable with respect to indemnification than are set forth in the Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws of Duke Energy immediately after the Effective Time, which provisions shall not be amended, repealed or otherwise modified for a period of six (6) years from the Effective Time in any manner that would affect adversely the rights thereunder of individuals who, at or prior to the Effective Time, were directors, officers, employees, fiduciaries or agents of Duke Energy, Spectra Energy or a member of the Spectra Energy Group, unless such modification shall be required by Law and then only to the minimum extent required by Law.

Section 10.8. Miscellaneous.

(a) Nothing in this Agreement shall be deemed to restrict Spectra Energy or Duke Energy, or any members of their respective Groups, from acquiring at its own expense any insurance Policy in respect of any Liabilities or covering any period. Except as otherwise provided in this Agreement, from and after the Effective Time, Spectra Energy and Duke Energy shall be responsible for obtaining and maintaining their respective insurance programs for their risk of loss and such insurance arrangements shall be separate programs apart from each other and each will be responsible for its own deductibles and retentions for such insurance programs.

(b) Each of the Parties intends by this Agreement that a third-party Person, including a third-party insurer or reinsurer, or other third-party Person that, in the absence of the Agreement would otherwise be obligated to pay any claim or satisfy any indemnity or other obligation, shall not be relieved of the responsibility with respect thereto and shall not be entitled to a “windfall” (i.e., avoidance of the obligation that such Person would have in the absence of this Agreement). To the extent that any such Person would receive such a windfall, the Parties shall negotiate in good faith concerning an amendment of this Agreement or the 100% Quota Share Reinsurance Agreements to avoid such a windfall.

Section 10.9. Captive Insurance.

(a) On or before the Effective Time, the Parties shall transfer, or retain, as applicable, the respective interests in the Captive Insurers, as follows:

(i) the assets and liabilities of Westcoast Indemnity Company Limited shall be retained by Westcoast Indemnity Company Limited (which shall be a member of the Spectra Energy Group);

(ii) the assets and liabilities of Cinergy Risk Solutions Ltd. shall be retained by Cinergy Risk Solutions Ltd. (which shall be a member of the Duke Energy Group);

(iii) the assets and liabilities of Bison Insurance Company Limited shall be allocated between Bison Insurance Company Limited and Spectra Energy Captive as set forth in Section 10.9(b), and Bison Insurance Company Limited shall be a member of the Duke Energy Group; and

(iv) the assets and liabilities of NorthSouth Insurance Company Limited shall be retained by NorthSouth Insurance Company Limited (which shall be a member of the Duke Energy Group).

(b) At the Effective Time (or such earlier time as the Parties may agree):

(i) Duke Energy or any of its Affiliates will transfer assets to Spectra Energy Captive in an amount sufficient to allow Spectra Energy Captive to meet its minimum regulatory capital requirement.

(ii) Bison Insurance Company Limited and Spectra Energy Captive will enter into a 100% Quota Share Reinsurance Agreement substantially in the form attached as Exhibit D hereto (the “100% Quota Share Reinsurance Agreement”), pursuant to which Bison Insurance Company will cede, and Spectra Energy Captive will reinsure, on an indemnity basis, all risks incurred by Bison Insurance Company Limited under Captive Gas Policies and certain workers’ compensation reimbursement policies, net of any collectible recoverables under the Third Party Shared Policies, in exchange for Bison Insurance Company Limited transferring assets to Spectra Energy Captive, on the Distribution Date, in an amount equal to the total amount of loss and expense reserves reasonably estimated by Bison Insurance Company Limited as of the Effective Time with respect to claims for which coverage is available under the Captive Gas Policies and certain workers’ compensation reimbursement policies, subject to the limitations set forth in this ARTICLE X, less the amount Bison Insurance Company Limited reasonably estimates to recover under the Third Party Shared Policies to satisfy such claims;

(iii) Bison Insurance Company Limited and Spectra Energy Captive will enter into a Trust Agreement substantially in the form attached as Exhibit E hereto (the “Trust Agreement”), pursuant to which Spectra Energy Captive will be required to collateralize its reinsurance obligations to Bison Insurance Company Limited by holding the assets that have been transferred to it by Bison Insurance Company Limited pursuant

to paragraph (c)(ii) above in a trust which shall name Bison Insurance Company Limited as its sole beneficiary;

(iv) Bison Insurance Company Limited and Spectra Energy Captive will enter into an Administrative Services Agreement substantially in the form attached as Exhibit F hereto (the “Administrative Services Agreement”), pursuant to which Spectra Energy Captive will provide all administrative services with respect to all the liabilities being reinsured under the 100% Quota Share Reinsurance Agreement; and

(v) Bison Insurance Company Limited and any other member of the Duke Energy Group that is a party to a Third Party Shared Policy, and each member of the Spectra Energy Group that holds a Captive Gas Policy or is a party to certain workers’ compensation policies will enter into an agreement to assign excess insurance recoverables substantially in the form attached as Exhibit G hereto, pursuant to which Bison Insurance Company Limited and any such other member of the Duke Energy Group will collaterally assign certain insurance recoverables under such Third Party Shared Policies to such members of the Spectra Energy Group. Such agreements to assignment excess insurance recoverables, the 100% Quota Share Reinsurance Agreement, the Trust Agreement and the Administrative Services Agreement shall collectively be referred to herein as the “100% Quota Share Reinsurance Agreements”).
