change, or any development involving a prospective change, in or affecting the condition (financial or otherwise), results of operations, stockholders’ equity, properties, management, business or prospects of Spectra Energy and its subsidiaries taken as a whole, the effect of which is, in the judgment of the Representatives, so material and adverse as to make it impracticable or inadvisable to proceed with the public offering or the delivery of the Securities being delivered on the Delivery Date on the terms and in the manner contemplated in the Pricing Disclosure Package and the Prospectus.

8. Indemnification and Contribution.

(a) Each of the Spectra Parties, jointly and severally, agrees to indemnify and hold harmless each Underwriter, the affiliates, directors, officers, employees and agents of any Underwriter and each person, if any, who controls any Underwriter within the meaning of either the Securities Act or the Exchange Act from and against any and all losses, claims, damages or liabilities, joint or several, to which that Underwriter, affiliate, director, officer, employee or contesting person may become subject under the Securities Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon: (i) any

untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus, the Prospectus, the Pricing Disclosure Package, any Issuer Free Writing Prospectus or in any amendment or supplement thereto, or (ii) the omission or the alleged omission to state in the Registration Statement, any Preliminary Prospectus, the Prospectus, the Pricing Disclosure Package, any Issuer Free Writing Prospectus or in any amendment or supplement thereto any material fact required to be stated therein or necessary to make the statements therein not misleading; and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Spectra Parties will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Spectra Parties by the Underwriters through the Representatives specifically for inclusion therein, which information consists solely of the information specified in Section 8(b). This indemnity agreement will be in addition to any liability which the Spectra Parties may otherwise have.

(b) Each Underwriter, severally and not jointly, agrees to indemnify and hold harmless each Spectra Party, the respective directors of the Spectra Parties, the respective officers of the Spectra Parties who signed the Registration Statement, and each person, if any, who controls the Spectra Parties within the meaning of either the Securities Act or the Exchange Act to the same extent as the foregoing indemnity from the Spectra Parties to the Underwriters, but only with reference to written information relating to the Underwriters furnished to the Spectra Parties by the Underwriters through the Representatives specifically for inclusion in the documents referred to in the foregoing indemnity; and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action. This indemnity agreement will be in addition to any liability which the Underwriters may otherwise have. The Spectra Parties acknowledge that the statements set forth in the most recent Preliminary Prospectus and the Prospectus: (A) the names of the Underwriters, (B) the last paragraph of the cover page regarding delivery of the Notes and (C) under the heading “Underwriting,” (1) the sentence relating to concessions in the second paragraph under the heading “Commissions and Expenses,” (2) the second sentence in the third paragraph under the heading “Commissions and Expenses,” and (3) the fourth, fifth and sixth paragraphs under the heading “Commissions and Expenses,” constitute the only information furnished in writing by or on behalf of the Underwriters for inclusion in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectuses or in any amendment or supplement thereto.

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of any claim or the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the claim or the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantive rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than

the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the reasonable fees, costs and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there is a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified parties from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the third sentence of this paragraph (c), the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and does not contain any statement as to or an admission of fault, culpability or failure to act by or on behalf of any indemnified party.

(d) In the event that the indemnity provided in this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Spectra Parties and the Underwriters agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) (collectively, the “Losses”) to which the Spectra Parties and the Underwriters may be subject in such proportion as is appropriate to reflect the relative benefits received by the Spectra Parties on the one hand and by the Underwriters on the other from the offering of the Securities; provided, however, that in no case shall (i) any Underwriter be responsible for any amount in excess of the amount by which the total price of the Notes underwritten by it and

distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Spectra Parties and the Underwriters shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Spectra Parties on the one hand and of the Underwriters on the other in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Spectra Parties shall be deemed to be equal to the total net proceeds from the Offering (before deducting expenses) received by it, and benefits received by the Underwriters shall be deemed to be equal to the total underwriting discounts and commissions, in each case as set forth on the cover page of the Prospectus. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Spectra Parties on the one hand or the Underwriters on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Spectra Parties and each of the Underwriters agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each person, if any, who controls any Underwriter within the meaning of either the Securities Act or the Exchange Act and each affiliate, director, officer, employee and agent of any Underwriter shall have the same rights to contribution as the Underwriters, and each person, if any, who controls the Spectra Parties within the meaning of either the Securities Act or the Exchange Act, each officer of the Spectra Parties who shall have signed the Registration Statement and each director of the Spectra Parties shall have the same rights to contribution as the Spectra Parties, subject in each case to the applicable terms and conditions of this paragraph (d). The Underwriters’ respective obligations to contribute pursuant to this paragraph (d) are several in proportion to the principal amount of Notes set forth opposite their respective names in Schedule I hereto and not joint.

9. No Fiduciary Duty. Each Spectra Party hereby acknowledges that each Underwriter is acting solely as an underwriter in connection with the purchase and sale of the Securities. Each Spectra Party further acknowledges that each Underwriter is acting pursuant to a contractual relationship created solely by this Agreement entered into on an arm’s-length basis and in no event do the parties intend that each Underwriter acts or be responsible as a fiduciary or financial advisor to any of the Spectra Entities, their management, stockholders, members, unitholders, creditors or any other person in connection with any activity that each Underwriter may undertake or have undertaken in furtherance of the purchase and sale of the Securities, either before or after the date hereof. Each Underwriter hereby expressly disclaims any fiduciary, agency, advisory or similar obligations to any of the Spectra Entities, either in connection with the transactions contemplated by this Agreement or any matters leading up to such transactions, and the Spectra Parties hereby confirm their understanding and agreement to that effect. The Spectra Parties and the Underwriters agree that they are each responsible for making their own independent judgments with respect to any such transactions and that any opinions or views expressed by the Underwriters to any of the Spectra Entities regarding such

transactions, including but not limited to any opinions or views with respect to the price or market for the Securities, do not constitute advice or recommendations to any of the Spectra Entities. Each Spectra Party hereby waives and releases, to the fullest extent permitted by law, any claims that any Spectra Party may have against each Underwriter with respect to any breach or alleged breach of any fiduciary, agency, advisory or similar duty to any of the Spectra Entities in connection with the transactions contemplated by this Agreement or any matters leading up to such transactions.

10. Defaulting Underwriters. If, on the Delivery Date, any Underwriter defaults in the performance of its obligations under this Agreement, the remaining non-defaulting Underwriters shall be obligated to purchase the principal amount of the Notes that the defaulting Underwriter agreed but failed to purchase on the Delivery Date in the respective proportions which the principal amount of the Notes set forth opposite the name of each remaining non-defaulting Underwriter in Schedule I hereto bears to the aggregate principal amount of the Notes set forth opposite the names of all the remaining non-defaulting Underwriters in Schedule I hereto; provided, however, that the remaining non-defaulting Underwriters shall not be obligated to purchase any of the Notes on the Delivery Date if the aggregate principal amount of the Notes that the defaulting Underwriter or Underwriters agreed but failed to purchase on such date exceeds 10% of the aggregate principal amount of the Notes to be purchased on the Delivery Date, and any remaining non-defaulting Underwriters shall not be obligated to purchase more than 110% of the principal amount of the Notes that it agreed to purchase on the Delivery Date pursuant to the terms of Section 2. If the foregoing maximums are exceeded, the remaining non-defaulting Underwriters, or those other underwriters satisfactory to the Representatives who so agree, shall have the right, but shall not be obligated, to purchase, in such proportion as may be agreed upon among them, the aggregate principal amount of the Notes to be purchased on the Delivery Date. If the remaining Underwriters or other underwriters satisfactory to the Representatives do not elect to purchase the Notes that the defaulting Underwriter or Underwriters agreed but failed to purchase on the Delivery Date, this Agreement shall terminate without liability on the part of any non-defaulting Underwriters or the Spectra Parties, except that the Spectra Parties will continue to be liable for the payment of expenses to the extent set forth in Sections 6 and 12. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context requires otherwise, any party not listed in Schedule I hereto that, pursuant to this Section 10, purchases Notes that a defaulting Underwriter agreed but failed to purchase.

Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Spectra Parties for damages caused by its default. If other Underwriters are obligated or agree to purchase the Notes of a defaulting or withdrawing Underwriter, either the Representatives or the Spectra Parties may postpone the Delivery Date for up to seven full business days in order to effect any changes that in the opinion of counsel for the Spectra Parties or counsel for the Underwriters may be necessary in the Registration Statement, the Prospectus or in any other document or arrangement.

11. Termination. The obligations of the Underwriters hereunder may be terminated by the Representatives by notice given to and received by Spectra Energy prior to delivery of and payment for the Notes if, prior to that time, any of the events described in Sections 7(j), 7(k) or 7(l) shall have occurred or if the Underwriters shall decline to purchase the Notes for any reason permitted under this Agreement.

12. Reimbursement of Underwriters’ Expenses. If the sale of the Securities provided for herein is not consummated because any condition to the obligations of the Underwriters set forth in Section 7 hereof is not satisfied, because of any termination pursuant to Section 7(j), 7(k) or 7(l) hereof or because of any refusal, inability or failure on the part of any Spectra Party to perform any agreement herein or comply with any provision hereof other than by reason of a default by the Underwriters, the Spectra Parties will reimburse the Underwriters, severally through the Representatives, on demand for all reasonable out-of-pocket expenses (including reasonable fees and disbursements of counsel) that shall have been incurred by the Underwriters in connection with the proposed purchase and sale of the Securities. If this Agreement is terminated pursuant to Section 10 hereof by reason of the default of one or more of the Underwriters, the Spectra Parties shall not be obligated to reimburse any defaulting Underwriter on account of such Underwriter’s expenses.

13. Research Analyst Independence. Each of the Spectra Parties acknowledges that the Underwriters’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that such Underwriters’ research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to each of the Spectra Parties and/or the offering that differ from the views of their respective investment banking divisions. Each of the Spectra Parties hereby waives and releases, to the fullest extent permitted by law, any claims that the Spectra Parties may have against the Underwriters with respect to any conflict of interest that may arise from the fact that the views expressed by their independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Spectra Parties by such Underwriters’ investment banking divisions. Each of the Spectra Parties acknowledges that each of the Underwriters is a full service securities firm and as such from time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of the companies that may be the subject of the transactions contemplated by this Agreement.
