As among each Series of the Partnership and the Partnership generally, the Primary Obligor with respect to an Intercompany Obligation shall have the primary responsibility for administering and discharging such obligation and shall have primary liability to the creditors or other obligees associated with such obligation.

(d) The Managing General Partner of the Partnership generally shall determine the portion of the Liabilities associated with or arising from the use, ownership or operation of the Shared Assets and that arise from events or circumstances occurring after the Closing Date to be designated as Series AC Liabilities or Series LH Liabilities (with respect to each Series, its “Proportionate Share of Shared Liabilities”) based on the following criteria (and the Managing

General Partners of the Series AC and the Series LH shall maintain the Series AC Records and the Series LH Records, respectively, in a manner consistent with such determination):

(i) the relative use by the Series AC and the Series LH of the Shared Asset to which the Liability relates;

(c) To effect the admission of any Partner to the Partnership generally or any Series, the Managing General Partner of the Partnership generally and each applicable Series shall take all steps necessary or appropriate under the Delaware Act to amend the records of the Partnership and the applicable Series to reflect such admission and, if necessary, notwithstanding Sections 12.1 or 12.2, to prepare and adopt as soon as practicable an amendment to this

(c) For so long as the Partnership is a partnership for U.S. federal income tax purposes, in no event may any Transfer of any Partnership Interests by any Partner be made if such Transfer is effectuated through an “established securities market” or a “secondary market (or the substantial equivalent thereof)” within the meaning of Section 7704 of the Code or if such Transfer would otherwise result in the Partnership or any Series being treated as a “publicly traded partnership,” as such term is defined in Section 7704(b) of the Code and the regulations promulgated thereunder.

The ROFR Offer Price shall be expressed in U.S. dollars, whether or not the form of consideration in the Third Party Offer is wholly or partially cash or cash equivalents.

(b) Each ROFR Holder shall have the right, but not the obligation, to purchase up to that amount of the Offered Interests equal to the product of (i) the amount of the Offered Interests and (ii) a fraction (the “ROFR Proportionate Share”), the numerator of which shall be the Series AC Percentage Interest of such ROFR Holder and the denominator of which shall be the sum of all of the Series AC Percentage Interests held by all ROFR Holders. Within 25 days after the ROFR Notice Date, each such ROFR Holder may deliver a written notice to the Offering Partner, the Managing General Partner of the Partnership generally and each other ROFR Holder of its election to purchase such Offered Interests. Any ROFR Holder whose written notice has not been received by the Managing General Partner of the Partnership generally within such 25-day period shall be deemed to have elected not to exercise its right of first refusal in connection with such Transfer. To the extent any such ROFR Holder does not elect to purchase its full ROFR Proportionate Share of such Offered Interests, each ROFR Holder that has elected to purchase its full ROFR Proportionate Share shall be entitled, by delivering written notice to the Offering Partner and the Managing General Partner of the Partnership generally within five Business Days following the end of such 25-day period (such fifth Business Day, the “ROFR Expiration Date”), to purchase up to all of the remaining Offered Interests. If there is an oversubscription, the oversubscribed amount shall be allocated among the

ROFR Holders fully exercising their rights to purchase such remaining Offered Interests pro rata based on the Series AC Percentage Interest owned by each fully-electing ROFR Holder. The delivery of a notice of election under this Section 4.4(b) shall constitute an irrevocable commitment to purchase such Offered Interests. If the ROFR Holders shall have elected to purchase all but not less than all of the Offered Interests, the Managing General Partner of the Partnership generally shall thereafter set a reasonable place and time for the closing of the purchase and sale of the Offered Interests, which shall be not less than 10 days nor more than 60 days after the ROFR Expiration Date (subject to extension to the extent necessary to pursue any required regulatory or Partner approvals, including to allow for the expiration or termination of all waiting periods under the HSR Act) unless otherwise agreed by all of the parties to such transaction.

(c) The purchase price and terms and conditions for the purchase of the Offered Interests pursuant to this Section 4.4 shall be the purchase price and terms and conditions set forth in the applicable Third Party Offer (or the cash equivalent thereof); provided that the purchase price shall be the ROFR Offer Price and shall be payable in immediately available U.S. dollars; and provided further that the Offering Partner shall at a minimum make customary representations and warranties concerning (i) such Offering Partner’s valid title to and ownership of the Offered Interests, free and clear of all liens, claims and encumbrances (excluding those arising hereunder and under applicable securities laws), (ii) such Offering Partner’s authority, power and right to enter into and consummate the sale of the Offered Interests, (iii) the absence of any violation, default or acceleration of any agreement or obligation to which such Offering Partner is subject or by which its assets are bound as a result of the sale of the Offered Interests and (iv) the absence of, or compliance with, any governmental or third party consents, approvals, filings or notifications required to be obtained or made by such Offering Partner in connection with the sale of the Offered Interests. The Offering Partner and participating ROFR Holders shall use commercially reasonable efforts to close the purchase of the Offered Interests as soon as reasonably practicable following the ROFR Expiration Date and shall each execute and deliver such instruments and documents and take such actions, including obtaining all applicable approvals and consents and making all applicable notifications and filings, as the other parties may reasonably request in order more effectively to implement the purchase and sale of the Offered Interests hereunder.

(d) Notwithstanding the foregoing, if (i) the ROFR Holders (A) shall have elected to purchase less than all of the Offered Interests or (B) shall not have elected to purchase any of the Offered Interests on or prior to the ROFR Expiration Date, and the Offering Partner has fully complied with the provisions of this Section 4.4, then the Offering Partner may sell all, but not less than all, of the Offered Interests within 90 days after the ROFR Expiration Date (subject to extension for a reasonable amount of time to the extent necessary to obtain any required regulatory or Partner approvals, including to allow for the expiration of all waiting periods under the HSR Act) or (ii) if the ROFR Holders fail to consummate the closing of the purchase and sale of the Offered Interests within the time period provided in the last sentence of Section 4.4(b) (such period, the “ROFR Closing Period”) and the Offering Partner has fully complied with the provisions of this Section 4.4, then the Offering Partner may sell all, but not less than all, of the Offered Interests within 90 days after the expiration of the ROFR Closing Period to the Third Party, in each case subject to the provisions of Section 4.2. Any such sale shall not be at less than the purchase price or upon terms and conditions more favorable in any material respect,

individually or in the aggregate, to the purchaser than those specified in the Third Party Offer. If the Offered Interests are not so transferred within the applicable time periods specified in this Section 4.4(d), the Offering Partner may not sell any of the Offered Interests without again complying in full with the provisions of this Article IV.

(e) Each of EECI and Enbridge Partners shall be entitled to assign any rights it has to purchase Offered Interests pursuant to this Section 4.4 to any of its Permitted Transferees.

(f) This Section 4.4 shall not apply to any Transfer or proposed Transfer of Partnership Interests to a Permitted Transferee.

Section 4.5 Tag-Along Rights.

(a) If a Series AC Partner (the “Transferor”) proposes to Transfer all or a part of its Series AC Partnership Interests to a Third Party (the “Tag-Along Transferee”), then such Transferor shall send written notice of such proposed Transfer (the “Tag-Along Notice”) to the other Series AC Partners (the “Tag Offerees”) at least 30 days prior to effecting such Transfer. Such Tag-Along Notice may be combined with a ROFR Notice and may be conditioned upon the ROFR Holders not exercising the right of first refusal contained in Section 4.4. The Tag-Along Notice shall set forth the identity of the Tag-Along Transferee (including, if such information is not publicly available, information about the identity of the Tag-Along Transferee and its Affiliates), the amount and the Series AC Partnership Interests to be Transferred, the proposed purchase price expressed in U.S. dollars (whether or not the form of consideration is wholly or partially cash or cash equivalents), all details of the payment terms, the time and place for the closing and all other material terms and conditions, including the nature of the representations and warranties to be made and the indemnities to be given, in connection with the proposed Transfer. Each of the Tag Offerees shall then have the irrevocable right (a “Tag-Along Right”), exercisable by delivery of an irrevocable notice to the Transferor at any time within 20 days after receipt of the Tag-Along Notice, to participate in such Transfer by selling to the Tag-Along Transferee a pro rata portion of such Tag Offeree’s Series AC Partnership Interests, based on the respective Tag Pro Rata Share of the Transferor and the other Tag Offerees that exercise their Tag-Along Right, on the same terms (including with respect to representations, warranties and indemnification) as the Transferor; provided, however, that (i) any representations and warranties relating specifically to any such Tag Offeree shall only be made by such Tag Offeree; (ii) any indemnification provided by the Transferor and any such Tag Offeree (other than with respect to the representations referenced in the foregoing subsection (i)) shall be based on the Series AC Percentage Interest being sold by each party in the proposed sale, either on a several, not joint, basis or solely with recourse to an escrow (such escrow not to exceed 25% of the proceeds received by the Tag Offerees that exercise their Tag-Along Right without the consent of such Tag Offerees) established for the benefit of the proposed purchaser (each party’s contributions to such escrow to be on a pro rata basis in accordance with the proceeds received from such sale), it being understood and agreed that any such indemnification obligation of any such Tag Offeree shall in no event exceed the net proceeds to such Tag Offeree from such proposed Transfer; and (iii) the form of consideration to be received by the Transferor in connection with the proposed sale shall be the same as that received by such Tag Offeree.

(b) If any Tag Offeree has exercised its Tag-Along Rights and the Tag-Along Transferee is unwilling to purchase all of the Series AC Partnership Interests proposed to be Transferred by the Transferor and each exercising Tag Offeree, then the Transferor and the exercising Tag Offerees shall reduce, on a pro rata basis, based on their respective Tag Pro Rata Share, the amount of such Series AC Partnership Interests that each otherwise would have sold so as to permit the Transferor and the exercising Tag Offerees to sell the portion of Series AC Partnership Interests (determined in accordance with such Tag Pro Rata Share) that the proposed Tag-Along Transferee is willing to purchase.

(c) Each Tag Offeree and the Transferor shall sell to the Tag-Along Transferee all of the Series AC Partnership Interests proposed to be Transferred by them, at not less than the purchase price payable in immediately available U.S. dollars and upon terms and conditions, if any, not more favorable in any material respect, individually and in the aggregate, to the Tag-Along Transferee than those in the Tag-Along Notice at the time and place provided for the closing in the Tag-Along Notice, or at such other time and place as the Tag Offerees, the Transferor and the Tag-Along Transferees shall agree.

(d) The Transferor shall have the right to require the Managing General Partner of the Series AC and the Managing General Partner of the Partnership generally to cooperate fully with potential acquirors of its Series AC Partnership Interests by taking all customary and other actions reasonably required by the Transferor or such potential acquirors, including making the records and assets of each Series and the Partnership generally reasonably available for inspection by such potential acquirors and making the officers and employees who manage the business of the Partnership and the Series reasonably available for interviews; provided that the potential acquirer has entered into a customary confidentiality agreement with the Partnership and the applicable Series. Neither the Managing General Partner of any Series nor the Managing General Partner of the Partnership generally shall be required to disclose to any potential acquirer (i) any information that such Managing General Partner reasonably believes to be in the nature of trade secrets or (ii) other information the disclosure of which such Managing General Partner reasonably believes (A) could damage the Partnership or any Series or their respective businesses or (B) that the Partnership or any Series is required by law or by agreement to keep confidential.

Section 4.6 Transfers of Certain Partnership Assets—ROFR.

(a) If the Partnership or any Series receives a bona fide written offer from a Third Party (a “Third Party Asset Offer”) for the transfer of any Series asset or group of related assets with a fair market value in excess of $5.0 million, and the Managing General Partner of the Series associated with such assets desires to accept and is otherwise permitted to effect such proposed transfer pursuant to this Section 4.6, such Managing General Partner shall deliver written notice of such Third Party Asset Offer (the “ROFR Asset Notice”) to EECI no less than 30 days prior to the date of the proposed Transfer. The date that the ROFR Asset Notice is received by EECI shall constitute the “ROFR Asset Notice Date.” The ROFR Asset Notice shall set forth the identity of the Third Party (including, if such information is not publicly available, information about the identity of the Third Party and its Affiliates), a description of the Series asset or group of related assets to be transferred (the “ROFR Offered Asset”), the proposed purchase price for the ROFR Offered Asset (the “ROFR Asset Offer Price”), all details of the

payment terms and all other material terms and conditions, including the nature of the representations and warranties to be made and the indemnities to be given, in connection with the proposed transfer. The ROFR Asset Offer Price shall be expressed in U.S. dollars, whether or not the form of consideration in the Third Party Asset Offer is wholly or partially cash or cash equivalents.

(b) For so long as EECI or any of its Affiliates is a holder of a Partnership Interest, EECI shall have the right, but not the obligation, to purchase the ROFR Offered Asset. Within 25 days after the ROFR Asset Notice Date (such 25th day, the “ROFR Asset Expiration Date”), EECI may deliver a written notice to the Managing General Partner of the applicable Series of its election to purchase such ROFR Offered Asset. The delivery of a notice of election under this Section 4.6 shall constitute an irrevocable commitment to purchase such ROFR Offered Asset. Such Managing General Partner shall thereafter set a reasonable place and time for the closing of the purchase and sale of the ROFR Offered Asset, which shall be not less than 10 days nor more than 60 days after the ROFR Asset Expiration Date (subject to extension to the extent necessary to pursue any required regulatory or Partner approvals, including to allow for the expiration or termination of all waiting periods under the HSR Act) unless otherwise agreed by all of the parties to such transaction.

(c) The purchase price and terms and conditions for the purchase of the ROFR Offered Asset pursuant to this Section 4.6 shall be the purchase price and terms and conditions set forth in the applicable Third Party Asset Offer; provided that the purchase price shall be the ROFR Asset Offer Price and shall be payable in immediately available U.S. dollars; and provided further that the applicable Series shall at a minimum make customary representations and warranties concerning (i) the Series’ valid title to and ownership of the ROFR Offered Asset, free and clear of all liens, claims and encumbrances (excluding those arising hereunder and under applicable securities laws), (ii) the Series’ authority, power and right to enter into and consummate the sale of the ROFR Offered Asset, (iii) the absence of any violation, default or acceleration of any agreement to which the Series is subject or by which its assets are bound as a result of the agreement to sell and the sale of the ROFR Offered Asset and (iv) the absence of, or compliance with, any governmental or third party consents, approvals, filings or notifications required to be obtained or made by the Series in connection with the sale of the ROFR Offered Asset. The Managing General Partner of such Series and EECI shall use commercially reasonable efforts to close the purchase of the ROFR Offered Asset as soon as reasonably practicable following the giving of the ROFR Asset Notice and shall execute and deliver such instruments and documents and take such actions, including obtaining all applicable approvals and consents and making all applicable notifications and filings, as the other party may reasonably request in order more effectively to implement the purchase and sale of the ROFR Offered Asset hereunder.

(d) If (i) EECI shall not have elected to purchase the ROFR Offered Asset on or prior to the ROFR Asset Expiration Date and the Series has fully complied with the provisions of this Section 4.6, then the Series may sell the ROFR Offered Asset within 90 days after the ROFR Asset Expiration Date (subject to extension for a reasonable amount of time to the extent necessary to obtain any required regulatory or Partner approvals, including to allow for the expiration of all waiting periods under the HSR Act) or (ii) EECI fails to consummate the closing of the purchase and sale of the ROFR Offered Asset within the time period provided in the last

sentence of Section 4.6(b) (such period, the “ROFR Asset Closing Period”) and the Series has fully complied with the provisions of this Section 4.6, then EECI shall not have the right to purchase the ROFR Offered Asset, and the Series may sell the ROFR Offered Asset within 90 days after the expiration of the ROFR Asset Closing Period, in each case subject to the provisions of Section 7.3. Any such sale shall not be at less than the purchase price or upon terms and conditions more favorable in any material respect, individually or in the aggregate, to the purchaser than those specified in the Third Party Asset Offer. If the ROFR Offered Asset is not so transferred within the applicable time periods specified in this Section 4.6(d), the Series may not sell the ROFR Offered Asset without again complying in full with the provisions of this Section 4.6.

(e) EECI shall be entitled to assign any rights it has to purchase a ROFR Offered Asset pursuant to this Section 4.6 to any of its Permitted Transferees.

(f) This Section 4.6 shall not apply to any transfer or proposed transfer of assets to a Permitted Transferee.

Section 4.7 Specific Performance.

Each Partner acknowledges that it shall be inadequate or impossible, or both, to measure in money the damage to the Partnership, any Series or the Partners, if any of them or any transferee or any legal representative of any party hereto fails to comply with any of the restrictions or obligations imposed by this Article IV, that every such restriction and obligation is material, and that in the event of any such failure, the Partnership, the Series and the Partners shall not have an adequate remedy at law or in damages. Therefore, each Partner consents to the issuance of an injunction or the enforcement of other equitable remedies against such Partner at the suit of an aggrieved party without the posting of any bond or other security, to compel specific performance of all of the terms of this Article IV and to prevent any transfer of Partnership Interests or ROFR Offered Assets in contravention of any terms of this Article IV, and waives any defenses thereto, including the defenses of: (i) failure of consideration; (ii) breach of any other provision of this Agreement and (iii) availability of relief in damages.

ARTICLE V

CONVERSION; CAPITAL CONTRIBUTIONS; PARTNERSHIP INTERESTS;

FUTURE CAPITAL REQUIREMENTS

Section 5.1 Conversion of Prior Partnership Interests.

On the date hereof, upon their execution of this Agreement and without further action by any Partner, the holders of each Prior General Partner Interest and Prior Limited Partner Interest shall be admitted as General Partners and Limited Partners, respectively, of Series LH, and each Prior General Partner Interest shall automatically convert into a Series LH General Partner Interest and each Prior Limited Partner Interest shall automatically convert into a Series LH Limited Partner Interest. Exhibit A sets forth the Series LH Percentage Interest and type of Series LH Partnership Interest of each Series LH Partner immediately following such conversion. In addition, Lakehead GP shall continue as a General Partner of the Partnership generally with a General Partner Interest in the Partnership generally that shall have no Percentage Interest and no economic rights with respect to the Partnership generally or otherwise.

Section 5.2 Series LH Capital Contributions.

Any Series LH Limited Partner, with the consent of the Managing General Partner of the Series LH, may, but shall not be obligated, to make additional Capital Contributions to the Series LH. Upon any such additional Capital Contribution, each Series LH General Partner and any other Series LH Limited Partner shall be obligated to make an additional Capital Contribution to the Series LH in an amount necessary to maintain its Series LH Percentage Interest.

Section 5.3 Initial Series AC Capital Contributions and Initial Debt Financing.

(a) On the Closing Date, each of the Series AC Partners shall make its respective Capital Contribution (each, an “Initial Series AC Capital Contribution”) to the Series AC in immediately available U.S. dollars in the amounts set forth opposite its name on Exhibit A in return for the Series AC Percentage Interest and type of Series AC Partnership Interest set forth opposite its name on Exhibit A, and, upon its execution of this Agreement and the making of its Initial Series AC Capital Contribution, each such Series AC Partner shall be admitted as a Partner of the Series AC in the capacity set forth opposite its name on Exhibit A.

(b) On the Closing Date, the Series AC shall (i) borrow under Facility B1 an amount equal to 66.67% of 45% of the Preliminary Alberta Clipper Construction Costs and (ii) borrow under Facility C1 an amount equal to 33.33% of 45% of the Preliminary Alberta Clipper Construction Costs.

(c) On the Closing Date, the Managing General Partner of Series AC shall apply the proceeds of the Initial Series AC Capital Contributions and the Initial Debt Financing to repay the Intercompany Preliminary Construction Cost Payable.

Section 5.4 Additional Series AC Capital Contributions.

(a) Each Series AC Partner hereby agrees to make additional Capital Contributions to the Series AC (the “Additional Series AC Capital Contributions”) in proportion to such Series AC Partner’s Series AC Percentage Interest at such times and in such amounts as the Managing General Partner of the Series AC shall specify in a notice delivered to the Series AC Partners pursuant to Section 5.4(b) or Section 5.4(c) (“Series AC Capital Contribution Notice”); provided that in no event shall any Series AC Partner be required to make, in the aggregate, Capital Contributions in excess of such Series AC Partner’s respective Maximum Commitment set forth on Exhibit A. All Additional Series AC Capital Contributions shall be contributed to the Series AC in immediately available U.S. dollars on the date specified in the applicable Series AC Capital Contribution Notice. No Series AC Partner shall be required to make any Additional Series AC Capital Contribution, or to otherwise contribute any amount, to the Series AC unless such Additional Series AC Capital Contribution is reflected on the Series AC Annual Budget for such fiscal year or is otherwise approved by the Managing General Partner of the Series AC and a Majority in Interest of Series AC Partnership Interests.

(b) On the 12th day of each month beginning prior to the In-Service Date, the Managing General Partner of the Series AC shall deliver a Series AC Capital Contribution Notice to each of the Series AC Partners setting forth (i) the estimated cash construction costs related to the Alberta Clipper Project for such month, adjusted for the difference between (A) the actual construction costs related to the Alberta Clipper Project for the immediately preceding month and (B) the estimated construction costs set forth in the Series AC Capital Contribution Notice for the immediately preceding month (the “Monthly Capital Requirement”), (ii) the amount of the required Additional Series AC Capital Contribution to be made by such Series AC Partner, which shall be an amount equal to such Series AC Partner’s Pro Rata portion of 55% of the Monthly Capital Requirement, (iii) that such Additional Series AC Capital Contribution is due on the 15th day of such month and (iv) the Person or the account to which such Additional Series AC Capital Contribution is to be made.

(c) From time to time following the In-Service Date, the Managing General Partner of the Series AC may deliver to the Series AC Partners a Series AC Capital Contribution Notice related to amounts that the Managing General Partner of the Series AC determines are necessary to fund the Series AC’s operations and establish reasonable reserves in respect of the Series AC’s expenses. Such notice shall set forth (i) the manner in which, and the expected date on which, such Additional Series AC Capital Contribution is to be applied, (ii) the amount of the required Additional Series AC Capital Contribution to be made by such Series AC Partner, which shall be an amount equal to such Series AC Partner’s Pro Rata portion of the total amount of such Additional Series AC Capital Contribution, (iii) the date on which such Additional Series AC Capital Contribution is due, which shall not be less than 10 Business Days from the date such notice is delivered and (iv) the Person or the account to which such Additional Series AC Capital Contribution is to be made.

(d) Each Series AC Partner agrees that payment of its required Additional Series AC Capital Contributions under this Agreement is an obligation of such Series AC Partner, that any default by any Series AC Partner would cause injury to the Series AC and to the other Series AC Partners and that the amount of damages caused by any such default would be difficult to calculate.

(e) If a Series AC Partner fails to fund all or any portion of its required Additional Series AC Capital Contribution set forth in a Series AC Capital Contribution Notice and fails to cure such default within five Business Days after the due date set forth in such Series AC Capital Contribution Notice (the “Default Capital Contribution”), the Series AC Partner failing to make such contribution (the “Defaulting Series AC Partner”) will be in default. Upon the occurrence of any such default, the Managing General Partner of Series AC shall promptly notify the Defaulting Series AC Partner and the other Series AC Partners not in default (each a “Non-Defaulting Series AC Partner”) of the occurrence of such default. As long as a Default Capital Contribution remains unpaid or arrangements for the payment thereof have not been agreed to by the Series AC Partners, any Non-Defaulting Series AC Partner may advance to the Series AC the entire amount of the Defaulting Series AC Partner’s Capital Contribution that has not been contributed, with each Non-Defaulting Series AC Partner electing to participate in such advance making its share of such advance in proportion to its Series AC Percentage Interest (without taking into account the Series AC Percentage Interest of the Defaulting Series AC Partner). Each Non-Defaulting Series AC Partner who makes such an advance on behalf of a Defaulting Series

AC Partner will have the right to elect the extent to which such advance will (x) constitute a loan to the Defaulting Series AC Partner and/or (y) be treated as a Capital Contribution by such Non-Defaulting Series AC Partner and result in an immediate adjustment of the Series AC Percentage Interests of the Defaulting Series AC Partner and the Non-Defaulting Series AC Partner making such election in accordance with Section 5.4(e)(i); provided, however, that if the advancing Non-Defaulting Series AC Partner does not notify the Managing General Partner of the Series AC of its election to have all, or any portion of, such advance treated as a loan to the Defaulting Series AC Partner, in writing, at the time the advance is made, then such advance shall be deemed a Capital Contribution and will automatically result in an immediate adjustment of the Series AC Percentage Interests.

(i) To the extent that one or more Non-Defaulting Series AC Partners do not elect to have an advance made pursuant to this Section 5.4(e) treated as a loan to the Defaulting Series AC Partner, or affirmatively elects to have such advance treated as a Capital Contribution, the Managing General Partner of the Series AC will automatically adjust the Series AC Percentage Interest of (A) each such Non-Defaulting Series AC Partner to equal the percentage obtained by dividing (x) the Series AC Capital Account of each such Non-Defaulting Series AC Partner (including any Capital Contribution made by such Non-Defaulting Series AC Partner under this Section 5.4(e) multiplied by three) by (y) the sum of the Series AC Capital Accounts of all Series AC Partners (including all Capital Contributions made under this Section 5.4(e) multiplied by three) and (B) such Defaulting Series AC Partner to equal the amount of (x) such Defaulting Series AC Partner’s Series AC Percentage Interest immediately prior to the occurrence of such default less (y) the aggregate increases to the Series AC Percentage Interests of Non-Defaulting Series AC Partners pursuant to clause (A). Notwithstanding the foregoing, the Defaulting Series AC Partner will have the right to re-acquire the interest in question from any advancing Non-Defaulting Series AC Partner within 30 days following the date on which such Series AC Percentage Interest adjustment is made by paying the entire amount advanced by such Non-Defaulting Series AC Partner in return for such adjustment, plus interest thereon at a rate equal to the lesser of (A) the maximum, lawful interest rate, compounded monthly, that is then-currently permitted under applicable law or (B) 12% per annum, whereupon the Series AC Percentage Interests of each Series AC Partner shall be adjusted to equal the Percentage Interest such Series AC Partner would have had in the absence of a default by such Defaulting Series AC Partner.

(ii) To the extent one or more Non-Defaulting Series AC Partners (each, a “Lending Series AC Partner”) elects to have an advance made pursuant to this Section 5.4(e) constitute a loan to the Defaulting Series AC Partner, such advance will have the following results (except to the extent otherwise agreed by the Lending Series AC Partner and the Defaulting Series AC Partner, each in their sole discretion):

(A) the sum advanced will constitute a loan from the Lending Series AC Partner to the Defaulting Series AC Partner and an Additional Series AC Capital Contribution of that sum to the Series AC by the Defaulting Series AC Partner pursuant to the applicable provisions of this Agreement;

(B) the principal balance of the loan together with all accrued unpaid interest thereon and all costs and expenses associated therewith (collectively, the “Defaulting Series AC Partner Obligation”) will be due and payable in whole no later than the tenth Business Day after the day written demand requesting payment of the Defaulting Series AC Partner Obligation is made by the Lending Series AC Partner to the Defaulting Series AC Partner; provided, however, that the Defaulting Series AC Partner may prepay the Defaulting Series AC Partner Obligation in whole or in part at any time prior to the date due;

(C) the amount lent will bear interest at the same rate as Facility B1 until such facility is repaid and, after Facility B1 has been repaid, at the same rate as the Enbridge Partners Long-Term Indebtedness from the date on which the advance is deemed made until the date on which the Defaulting Series AC Partner Obligation is repaid to the Lending Series AC Partner;

(D) the Lending Series AC Partner will have the right, in addition to the other rights and remedies granted to it pursuant to this Agreement, to take any action available to it at law or in equity that the Lending Series AC Partner may deem appropriate to obtain payment from the Defaulting Series AC Partner of the Defaulting Series AC Partner Obligation; and

(E) initially, a loan by a Lending Series AC Partner to a Defaulting Series AC Partner as contemplated by this Section 5.4(e)(ii) will not be considered a Capital Contribution by such Lending Series AC Partner and will not increase the Capital Account balance of such Lending Series AC Partner. Notwithstanding the foregoing, if the principal and interest of any such loan have not been repaid within one year from the date of the loan, a Lending Series AC Partner, at any time thereafter by giving written notice to the Managing General Partner of the Series AC and the Defaulting Series AC Partner, may elect to have an amount equal to the unpaid principal and interest balance of such loan transferred from such Defaulting Series AC Partner’s Capital Account to such Lending Series AC Partner’s Capital Account and increase such Lending Series AC Partner’s Capital Account with a corresponding decrease in such Defaulting Series AC Partner’s Capital Account. Upon such transfer, the loan will be treated as a Capital Contribution and the Series AC Percentage Interest for (A) such Lending Series AC Partner will be automatically adjusted to equal the percentage obtained by dividing (x) the Capital Account of such Lending Series AC Partner (including any Capital Contribution made by such Lending Series AC Partner under this Section 5.4(e)(ii)(E) on behalf of the Defaulting Series AC Partner multiplied by three) by (y) the sum of the Series AC Capital Accounts of all Series AC Partners (including all Capital Contributions made under this Section 5.4(e)(ii)(E) on behalf of the Defaulting Series AC Partner multiplied by three) and (B) such Defaulting Series AC Partner will be automatically adjusted to equal the amount of (x) such Defaulting Series AC Partner’s Series AC Percentage Interest immediately prior to such election by the Lending Series AC Partner less (y) the increase to the Series AC Percentage Interest of Lending Series AC Partner pursuant to clause (A).

(f) Notwithstanding the rights of Non-Defaulting Series AC Partners described in Section 5.4(e), the Managing General Partner of the Series AC, by a vote of a Majority in Interest of Series AC Partnership Interests (without taking into account the Series AC Partnership Interests of the Defaulting Series AC Partner), will have the right to exercise any rights and remedies available at law or in equity.

Section 5.5 Additional Debt Financing.

(a) On the 15th day of each month beginning prior to the In-Service Date, the Series AC shall (i) to the extent funded by EECI to Enbridge Partners under Facility A1, borrow under Facility B1 an amount equal to 66.67% of 45% of the Monthly Capital Requirement set forth in the Series AC Capital Contribution Notice for such month delivered to the Series AC Partners pursuant to Section 5.4(b) and (ii) borrow under Facility C1 an amount equal to 33.33% of 45% of the Monthly Capital Requirement set forth in the Series AC Capital Contribution Notice for such month delivered to the Series AC Partners pursuant to Section 5.4(b). The proceeds of such borrowings shall be used to fund construction costs related to the Alberta Clipper Project.

(b) On the 15th day of each month beginning prior to the In-Service Date, Enbridge Partners shall borrow under Facility A1 an amount equal to 66.67% of 45% of the Monthly Capital Requirement set forth in the Series AC Capital Contribution Notice for such month delivered to the Series AC Partners pursuant to Section 5.4(b). The proceeds of such borrowings shall be used to fund the borrowings under Facility B1 pursuant to Section 5.5(a).

(c) Promptly following the In-Service Date, Enbridge Partners shall use its commercially reasonable efforts to issue senior unsecured Indebtedness in an amount sufficient to refinance the outstanding borrowings under Facility C1 on such date in accordance with Section 3(d) of the Tariff Term Sheet (the “Enbridge Partners Long-Term Indebtedness”). The proceeds of the Enbridge Partners Long-Term Indebtedness shall be loaned to the Series AC on substantially the same terms as the Enbridge Partners Long-Term Indebtedness in order to refinance the outstanding borrowings under Facility C1.

(d) On the date of issuance of the Enbridge Partners Long-Term Indebtedness, EECI shall loan to Enbridge Partners on substantially the same terms as the Enbridge Partners Long-Term Indebtedness an amount sufficient to refinance the outstanding borrowings under Facility B1 on such date. The proceeds of such loan shall be loaned by Enbridge Partners to the Series AC on substantially the same terms as the Enbridge Partners Long-Term Indebtedness in order to refinance the outstanding borrowings under Facility B1.

Section 5.6 Future Alberta Clipper Expansions.

(a) Any Series AC Partner may from time to time propose an expansion of the capacity of the Alberta Clipper Project (each, an “Alberta Clipper Expansion Project”) by providing a written proposal setting forth in reasonable detail the terms of such Alberta Clipper Expansion Project, including a budget and capital expenditure plan (an “Alberta Clipper Expansion Proposal”), to each Series AC Partner. Promptly following its receipt of an Alberta Clipper Expansion Proposal, the Managing General Partner of the Series AC shall use its commercially reasonable efforts to develop, and negotiate with shippers regarding, the tolling and other financial terms for such Alberta Clipper Expansion Project that include objectively determinable incremental revenues and costs (the “Alberta Clipper Expansion Project Terms”) that are as favorable to the Alberta Clipper Expansion Project as can reasonably be achieved; provided, however, that the Managing General Partner of the Series AC shall not be obligated to seek any Alberta Clipper Expansion Project Terms that could reasonably be expected to have a

material adverse impact on any Series. The Managing General Partner of the Series AC shall not agree to any Alberta Clipper Expansion Project Terms that could reasonably be expected to have a material adverse impact on any Series without the consent of a Majority in Interest of such Series (excluding for purposes of any such vote of the Series AC Partners or the Partners of an Alberta Clipper Expansion Series that is not wholly owned by any Partner and its Affiliates (i) prior to the occurrence of a Fundamental Change, the Partnership Interests owned by the Managing General Partner of the Series AC and its Affiliates and (ii) following the occurrence of a Fundamental Change, the Partnership Interests owned by EECI and its Affiliates). The Managing General Partner of the Series AC shall provide written notice of the Alberta Clipper Expansion Project Terms to each Series AC Partner promptly following the determination of the Alberta Clipper Expansion Project Terms.

(b) Enbridge Partners shall have the right, but not the obligation, to provide all or any portion of the debt and equity financing required in connection with each Alberta Clipper Expansion Project (the “Alberta Clipper Expansion Capital Requirement”) by providing written notice of its election to participate in the Alberta Clipper Expansion Project to the Series AC Partners as soon as reasonably practicable but in any event within 30 days following the receipt of the Alberta Clipper Expansion Project Terms. If Enbridge Partners does not elect to fund 100% of the Alberta Clipper Expansion Capital Requirement, EECI shall have the right, but not the obligation, to fund the portion of the Alberta Clipper Expansion Capital Requirement that Enbridge Partners has elected not to fund. If EECI elects to fund such portion, it shall provide written notice to Enbridge Partners promptly following receipt of Enbridge Partners’ notice of election to fund a portion of the Alberta Clipper Expansion Capital Requirement. If EECI and/or Enbridge Partners do not elect to fund 100% of the Alberta Clipper Expansion Capital Requirement, then the Alberta Clipper Expansion Project will not be undertaken by the Partnership or any Series. Enbridge Partners and EECI may fund their respective portions of any Alberta Clipper Expansion Capital Requirement pursuant to this Section 5.6 either directly or through a Subsidiary or a controlled Affiliate.

(c) If the Alberta Clipper Expansion Capital Requirement is to be provided Pro Rata by the Series AC Partners, all assets related to such Alberta Clipper Expansion Project shall be designated as Series AC Assets, and all Liabilities related to such Alberta Clipper Expansion Project shall be designated as Series AC Liabilities. Capital Contributions associated with such Alberta Clipper Expansion Project shall be Additional Series AC Capital Contributions.

(d) The assets of any Alberta Clipper Expansion Project that is undertaken but that are not designated as Series AC Assets shall be designated as the assets of a new series of partnership interests in the Partnership to be held by the Partners participating in such Alberta Clipper Expansion Project in proportion to their respective capital contributions in respect of such Alberta Clipper Expansion Project (an “Alberta Clipper Expansion Series”). Subject to Section 7.3, the Managing General Partner of the Partnership generally is hereby authorized to take all actions necessary to create and establish the Alberta Clipper Expansion Series with such rights, powers and duties as the Managing General Partner of the Partnership generally and the Persons becoming Partners of such new Series shall determine, including to amend this Agreement and its exhibits to set forth all relevant terms applicable to such Series. The Persons becoming Partners of such Alberta Clipper Expansion Series shall be admitted to the Partnership with respect to such Series as Partners upon their execution of a counterpart to this Agreement in their capacity as Partners of such Alberta Clipper Expansion Series.

Section 5.7 Interest and Withdrawal of Capital Contributions.

No interest shall be paid by the Partnership or any Series on Capital Contributions. No Partner shall be entitled to the withdrawal or return of its Capital Contribution, except to the extent, if any, that distributions made pursuant to this Agreement or upon dissolution of the Partnership or the termination of any Series may be considered as such by law and then only to the extent expressly provided for in this Agreement. Except to the extent expressly provided in this Agreement, no Partner shall have priority over any other Partner either as to the return of Capital Contributions or as to Profits, Losses or distributions. Any such return shall be a compromise to which all Partners agree within the meaning of Section 17-502(b) of the Delaware Act.

Section 5.8 Capital Accounts.

(a) A separate Capital Account shall be established and maintained for each Partner in accordance with the requirements of Treasury Regulation Section 1.704-1(b)(2)(iv). A Partner that owns a Partnership Interest in more than one Series shall have a single Capital Account that reflects all such Partnership Interests; provided, however, that Series Capital Accounts shall be maintained for each Partner in accordance with the requirements of Treasury Regulation Section 1.704-1(b)(2)(iv). A Partner’s Capital Account balance shall be the sum of the balances of each of such Partner’s Series Capital Accounts.

(b) Each Series Capital Account for each Partner shall be increased by (i) the amount of money contributed by that Partner to the Partnership with respect to a Series, (ii) the Book Value of property contributed by that Partner to the Partnership with respect to a Series (net of liabilities secured by such contributed property that the Partnership is considered to assume or take subject to under Section 752 of the Code), and (iii) allocations to that Partner of Profits and any other items of income and gain attributable to a Series, and shall be decreased by (iv) the amount of money of a Series distributed to that Partner, (v) the Book Value of property of a Series distributed to that Partner (net of liabilities secured by such distributed property that such Partner is considered to assume or take subject to under Section 752 of the Code), and (vi) allocations to that Partner of Losses and any other items of loss and deduction attributable to a Series.

(c) The Partners’ Series Capital Accounts shall also be maintained and adjusted as permitted by the provisions of Treasury Regulation § 1.704-1(b)(2)(iv)(f) and as required by the other provisions of Treasury Regulation §§ 1.704-1(b)(2)(iv) and 1.704-1(b)(4).

(e) On a Transfer of all or part of a Partner’s Partnership Interest, each applicable Series Capital Account of the transferor that is attributable to the transferred Partnership Interests shall carry over to the transferee Partner in accordance with the provisions of Treasury Regulation § 1.704-1(b)(2)(iv)(1).

ARTICLE VI

ALLOCATIONS AND DISTRIBUTIONS

Section 6.1 Allocations for Capital Account Purposes.

(a) Allocations. For purposes of maintaining the Series Capital Accounts pursuant to Section 5.8 and in determining the rights of the Partners among themselves with respect to each Series, after making all of the allocations under Sections 6.1(b) and 6.1(c), Profits and Losses and items thereof with respect to a Series shall be allocated among the Partners of such Series in each taxable year (or portion thereof) as provided herein below.

(i) Series AC. Each item of income, gain, loss, deduction and credit attributable to Series AC Assets and Series AC Liabilities shall be allocated to the Series AC Partners in accordance with their respective Series AC Percentage Interests.

(ii) Series LH. Each item of income, gain, loss, deduction and credit attributable to Series LH Assets and Series LH Liabilities shall be allocated to the Series LH Partners in accordance with their respective Series LH Percentage Interests.

(iii) Notwithstanding Sections 6.1(a)(i) and 6.1(a)(ii), in the event of the dissolution and liquidation of the Partnership or the termination of a Series, allocations of Profit and Loss, and items thereof in connection with the liquidation shall be made in accordance with Section 11.3(a).

Losses and other items of deduction and loss specially allocated to a Partner with respect to a Series shall not exceed the maximum amount of Losses and items of deduction and loss that can be allocated without causing such Partner to have a deficit in its Adjusted Capital Account for such Series at the end of any taxable year or other period. In the event that some but not all of the Partners would have a deficit in their Adjusted Capital Accounts for such Series as a consequence of an allocation pursuant to this Section 6.1, the limitation set forth in the preceding sentence shall be applied on a Partner by Partner basis, and Losses or items of deduction and loss not allocable to any Partner as a result of such limitation shall be allocated to the other Partners of such Series in accordance with and to the extent of the relative positive balances in such Partners’ Adjusted Capital Accounts attributable to such Series. Any excess Losses or other items of deduction and loss remaining shall be allocated, Pro Rata, to the Partners of any other Series whose Adjusted Capital Accounts for such other Series have positive balances to the extent of such positive balances.

(b) Special Allocations. Notwithstanding any other provisions of this Section 6.1, the following special allocations shall be made on a Series by Series basis in the following order for each taxable period:

(i) Notwithstanding any other provision of this Section 6.1, if there is a net decrease in Minimum Gain attributable to a Series during any taxable year, each Partner of such Series shall be allocated items of income and gain attributable to such Series for such year (and,

if necessary, subsequent taxable years) in the manner and amounts provided in Treasury Regulation Sections 1.704-2(f)(6), (g)(2) and (j)(2)(i). For purposes of this Section 6.1(b), each Partner’s Adjusted Capital Account balance for such Series shall be determined, and the allocation of income or gain required hereunder shall be effected, prior to the application of any other allocations pursuant to this Section 6.1 with respect to such taxable year. This Section 6.1(b)(i) is intended to comply with the minimum gain chargeback requirement in Treasury Regulation Section 1.704-2(f) and shall be interpreted consistently therewith.

(ii) Notwithstanding the other provisions of this Section 6.1 (other than Section 6.1(b)(i) above), if there is a net decrease in Partner Nonrecourse Debt Minimum Gain attributable to a Series during any taxable year, any Partner with a share of such Partner Nonrecourse Debt Minimum Gain at the beginning of such taxable year shall be allocated items of income and gain attributable to such Series for such year (and, if necessary, subsequent taxable years) in the manner and amounts provided in Treasury Regulation Section 1.704-2(i)(4) and (j)(2)(ii). For purposes of this Section 6.1(b), each Partner’s Adjusted Capital Account balance shall be determined, and the allocation of income and gain required hereunder shall be effected, prior to the application of any other allocations pursuant to this Section 6.1, other than Section 6.1(b)(i) above, with respect to such taxable year. This Section 6.1(b)(ii) is intended to comply with the partner nonrecourse debt minimum gain chargeback requirement in Treasury Regulation Section 1.704-2(i)(4) and shall be interpreted consistently therewith.

(iii) Except as provided in Sections 6.1(b)(i) and 6.1(b)(ii) above, in the event any Partner unexpectedly receives an adjustment, allocation or distribution described in Treasury Regulation Sections 1.704-1(b)(2)(ii)(d)(4), (5) or (6) attributable to a Series, items of income and gain of such Series shall be allocated to such Partner in an amount and manner sufficient to eliminate, to the extent required by such Treasury Regulation, the deficit balance, if any, in its Adjusted Capital Account attributable to such Series created by such adjustment, allocation or distribution as quickly as possible unless such deficit balance is otherwise eliminated pursuant to Sections 6.1(b)(i), 6.1(b)(ii), 6.1(b)(iv) or 6.1(b)(v). This Section 6.1(b)(iii) is intended to constitute a qualified income offset described in Treasury Regulation Section 1.704-1(b)(2)(ii)(d) and shall be interpreted consistently therewith.

(iv) After giving effect to the allocations in Sections 6.1(b)(i), 6.1(b)(ii) and 6.1(b)(iii):

(A) in the event that the Series LH Partners become obligated to make payments to the Series AC Partners pursuant to Section 6.2(c), items of Partnership gross income and gain shall be allocated to the Series LH Partners in accordance with their respective Series LH Percentage Interests until the aggregate amounts of items allocated to the Series LH Partners pursuant to this Section 6.1(b)(iv) for such taxable year and all prior taxable years equals the cumulative amount of payments made by the Series LH Partners to the Series AC Partners pursuant to Section 6.2(c) for such taxable year and all prior taxable years; and

(B) in the event that the Series AC Partners become obligated to make payments to the Series LH Partners pursuant to Section 6.3(c), items of Partnership gross income and gain shall be allocated to the Series AC Partners in accordance with their respective Series AC Percentage Interests until the aggregate amounts of items allocated to the Series AC

Partners pursuant to this Section 6.1(b)(iv) for such taxable year and all prior taxable years equals the cumulative amount of payments made by the Series AC Partners to the Series LH Partners pursuant to Section 6.3(c) for such taxable year and all prior taxable years.

(v) In the event any Partner has a deficit balance in its Adjusted Capital Account attributable to a Series at the end of any taxable year, such Partner shall be allocated items of gross income and gain of such Series in the amount of such excess as quickly as possible; provided, however, that an allocation pursuant to this Section 6.1(b)(v) shall be made only if and to the extent that such Partner would have a deficit balance in its Adjusted Capital Account for such Series after all other allocations provided in this Section 6.1(b) (other than Section 6.1(b)(iii)) have been tentatively made as if Section 6.1(b)(iii) and this Section 6.1(b)(v) were not in this Agreement.

(vi) Nonrecourse Deductions attributable to a Series for any taxable year shall be allocated to the Partners of such Series in accordance with their Percentage Interests for such Series.

(vii) Partner Nonrecourse Deductions with respect to a Partner Nonrecourse Debt for any taxable year shall be allocated 100% to the Partner that bears the Economic Risk of Loss with respect to the Partner Nonrecourse Debt to which such Partner Nonrecourse Deductions are attributable in accordance with Treasury Regulation Section 1.704-2(i). If more than one Partner bears the Economic Risk of Loss with respect to a Partner Nonrecourse Debt, Partner Nonrecourse Deductions attributable thereto shall be allocated between or among such Partners in accordance with the ratios in which they share such Economic Risk of Loss. This Section 6.1(b)(vii) is intended to comply with the provisions of Treasury Regulation Section 1.704-2(i) and shall be interpreted consistently therewith.

(viii) To the extent an adjustment to the adjusted tax basis of any asset pursuant to Code Sections 734(b) or 743(b) is required, pursuant to Treasury Regulation Section 1.704-1(b)(2)(iv)(m), to be taken into account in determining Capital Accounts as a result of a distribution in liquidation of a Partner’s Partnership Interest in a Series, the amount of such adjustment to the Capital Accounts shall be treated as an item of gain (if the adjustment increases the basis of the asset) or loss (if the adjustment decreases such basis), and such item of gain or loss shall be allocated to the Partners in a manner consistent with the manner in which their Series Capital Accounts are required to be adjusted pursuant to such provisions.

(c) Curative Allocation. The Regulatory Allocations are intended to comply with certain requirements of the Treasury Regulations. It is the intent of the Partners that, to the extent possible, all Regulatory Allocations attributable to a Series shall be offset either with other Regulatory Allocations attributable to such Series, or with special allocations of other items of income, gain, loss or deduction attributable to such Series pursuant to this Section 6.1(c). Therefore, notwithstanding any other provision of this Article VI (other than the Regulatory Allocations), but subject to the Code and the Treasury Regulations, the Managing General Partner of the applicable Series shall make such offsetting special allocations of income, gain, loss or deduction in whatever manner it determines appropriate so that, after such offsetting allocations are made, each Partner’s applicable Series Capital Account balance is, to the extent possible, equal to the balance such Partner would have had if the Regulatory Allocations were

not part of this Agreement. In exercising its discretion under this Section 6.1(c), the Managing General Partner of the applicable Series shall take into account future Regulatory Allocations that, although not yet made, are likely to offset other Regulatory Allocations previously made.

(d) Income Tax Allocations.

(i) Except as otherwise provided in this Section 6.1, each item of income, gain, loss and deduction of a Series shall be allocated among the Partners of such Series for U.S. federal income tax purposes in the same manner as such items are allocated under Sections 6.1(a), 6.1(b) and 6.1(c).

(ii) For U.S. federal income tax purposes, income, gain, loss and deduction with respect to property contributed to a Series by a Partner or the Book Value of which is adjusted pursuant to clause (b) or (d) of the definition of Book Value shall be allocated among the Partners of such Series in a manner that takes into account the variation between the adjusted tax basis of such property and its Book Value, as required by Section 704(c) of the Code and Treasury Regulation Section 1.704-1(b)(4)(i), using the remedial allocation method permitted by Treasury Regulation Section 1.704-3(d).

(iii) All items of income, gain, loss, deduction and credit allocated to the Partners in accordance with the provisions hereof and basis allocations recognized by a Series for U.S. federal income tax purposes shall be determined without regard to any election under Code Section 754 that may be made by the Series.

(iv) If any deductions for depreciation or cost recovery are recaptured as ordinary income upon the sale or other disposition of property of a Series, the ordinary income character of the gain from such sale or disposition shall be allocated among the Partners of such Series in the same ratio as the deductions giving rise to such ordinary income character were allocated.

Section 6.2 Requirement and Characterization of Series AC Distributions; Distributions to Series AC Partners.

(a) Within 45 days following the end of each Quarter commencing with the Quarter in which the In-Service Date occurs, the Partnership in respect of the Series AC shall distribute Pro Rata to the Series AC Partners as of the last day of such Quarter an amount in cash equal to the Series AC Distribution Amount with respect to such Quarter (the “Series AC Distribution”). Notwithstanding any provision to the contrary contained in this Agreement, neither the Partnership nor the Series AC shall make any distribution to any Series AC Partner on account of its Partnership Interest if such distribution would violate the Delaware Act or any other applicable law or violate Section 10.4(a) of the Note Agreement.

(b) Notwithstanding Section 6.2(a), in the event of the dissolution and liquidation of the Partnership or the termination of the Series AC, all cash receipts received during or after the Quarter in which the Liquidation Date occurs shall be applied and distributed solely in accordance with, and subject to the terms and conditions of, Section 11.3.

(c) If, for any Quarter (including the Quarter in which the liquidation of the Series AC is completed), the cash that is distributed by the Partnership to the Series AC Partners is less than the Series AC Distribution Amount for such Quarter, then the Series LH Partners shall promptly pay to the Series AC Partners Pro Rata in cash an amount equal to such shortfall.

Section 6.3 Distributions to Series LH Partners.

(a) On the date the Series AC Distribution is made pursuant to Section 6.2(a), the Managing General Partner of the Series LH may, in its sole discretion, cause the Partnership in respect of the Series LH to distribute Pro Rata to the Series LH Partners any cash that is not otherwise required under this Agreement to be distributed to the Partners of any other Series or properly reserved by any other Series in accordance with this Agreement (the “Series LH Distribution”). Notwithstanding any provision to the contrary contained in this Agreement, neither the Partnership nor Series LH shall make any distribution to any Series LH Partner on account of its Series LH Partnership Interest if such distribution would violate the Delaware Act or other applicable law or violate Section 10.4(a) of the Note Agreement.

(b) Notwithstanding Section 6.3(a), in the event of the dissolution and liquidation of the Partnership or the termination of the Series LH, all cash receipts received during or after the Quarter in which the Liquidation Date occurs shall be applied and distributed solely in accordance with, and subject to the terms and conditions of, Section 11.3.

(c) If, for any Quarter (including the Quarter in which the liquidation of the Series LH is completed), the Series AC Distribution Amount is less than zero, then the Series AC Partners shall promptly pay to the Series LH Partners Pro Rata in cash an amount equal to the amount by which the Series AC Distribution Amount was less than zero.

(a) To the fullest extent permitted by law but subject to the limitations expressly provided in this Agreement, each Series shall indemnify and hold harmless all of such Series’ Indemnitees from and against any and all losses, claims, damages, liabilities, joint or several, expenses (including legal fees and expenses), judgments, fines, penalties, interest, settlements or other amounts (“Damages”) arising from any and all claims, demands, actions, suits or proceedings, whether civil, criminal, administrative or investigative (“Claims”), in which any such Indemnitee may be involved, or is threatened to be involved, as a party or otherwise, by reason of its management of the affairs of such Series or by reason of its status as an Indemnitee of such Series, that relates to or arises out of such Series, its property, its business or its affairs; provided, that the Indemnitee shall not be indemnified and held harmless if there has been a final and non-appealable judgment entered by a court of competent jurisdiction determining that, in respect of the matter for which the Indemnitee is seeking indemnification pursuant to this Section 7.7, the Indemnitee acted in bad faith or engaged in fraud, willful misconduct or, in the case of a criminal matter, acted with knowledge that the Indemnitee’s conduct was unlawful. Any indemnification pursuant to this Section 7.7 shall be made only out of the assets of the indemnifying Series, it being agreed that, except as provided in Section 11.7, no Partner shall be personally liable for such indemnification nor shall any Partner have any obligation to contribute or loan any monies or property to such Series to enable it to effectuate such indemnification.

(b) To the fullest extent permitted by law, expenses (including legal fees and expenses) incurred by an Indemnitee who is indemnified pursuant to Section 7.7(a) in defending any Claim shall, from time to time, be advanced by the indemnifying Series prior to a determination that the Indemnitee is not entitled to be indemnified upon receipt by such Series of an undertaking by or on behalf of the Indemnitee to repay such amount if it shall be determined that the Indemnitee is not entitled to be indemnified as authorized in this Section 7.7.

(c) The indemnification provided by this Section 7.7 shall be in addition to any other rights to which an Indemnitee may be entitled under any agreement, pursuant to any vote of a Majority in Interest of the indemnifying Series, as a matter of law or otherwise, both as to actions in the Indemnitee’s capacity as an Indemnitee and as to actions in any other capacity, and shall continue as to an Indemnitee who has ceased to serve in such capacity and shall inure to the benefit of the heirs, successors, assigns and administrators of the Indemnitee.

(d) Any Series may purchase and maintain (or reimburse such Series’ General Partners or their Affiliates for the cost of) insurance, on behalf of such Series’ General Partners, their Affiliates and such other Persons as such Series’ General Partners shall determine, against any liability that may be asserted against, or expense that may be incurred by, such Person in connection with such Series’ activities or such Person’s activities on behalf of such Series, regardless of whether such Series would have the power to indemnify such Person against such liability under the provisions of this Agreement.

(e) In no event may an Indemnitee subject any Partner to personal liability by reason of the indemnification provisions set forth in this Agreement.

(f) An Indemnitee shall not be denied indemnification in whole or in part under this Section 7.7 because the Indemnitee had an interest in the transaction with respect to which the indemnification applies if the transaction was otherwise permitted by the terms of this Agreement with respect to the indemnifying Series.

(g) The provisions of this Section 7.7 are for the benefit of the Indemnitees, their heirs, successors, assigns and administrators and shall not be deemed to create any rights for the benefit of any other Persons.

(h) No amendment, modification or repeal of this Section 7.7 or any provision hereof shall in any manner terminate, reduce or impair the right of any past, present or future Indemnitee to be indemnified by a Series, nor the obligations of such Series to indemnify any such Indemnitee under and in accordance with the provisions of this Section 7.7 as in effect immediately prior to such amendment, modification or repeal with respect to Claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such Claims may arise or be asserted.

(i) The provisions of this Section 7.7 shall not be construed to limit the power of any Series to indemnify an Indemnitee of such Series to the fullest extent permitted by law or to enter into specific agreements, commitments or arrangements for indemnification permitted by law. The absence of any express provision for indemnification herein shall not limit any right of indemnification existing independently of this Section 7.7.

Section 7.8 Interseries Indemnification.

Notwithstanding anything to the contrary set forth in this Agreement, in the event that any Series (the “Indemnified Series”) (a) becomes liable for any Liability of another Series (the “Indemnifying Series”), including any Claim for Damages by a Third Party that relate to or arise out of the actions, obligation, assets, property, business or affairs of the Indemnifying Series or (b) pays or discharges an Intercompany Obligation for which the Indemnifying Series is the Primary Obligor (collectively, “Series Indemnified Damages”), to the fullest extent permitted by law, the Indemnifying Series shall indemnify the Indemnified Series for the amount of the Series Indemnified Damages promptly following their incurrence or payment, as applicable. Any indemnification pursuant to this Section 7.8 shall be made (i) only out of the assets of the Indemnifying Series, it being agreed that, except as provided in Section 11.7, no Partner shall be personally liable for such indemnification nor shall any Partner have any obligation to contribute

or loan any monies or property to the Indemnifying Series to enable it to effectuate such indemnification and (ii) only to the extent that the Partners of the Indemnified Series have not received a payment from the Partners of the Indemnifying Series under Section 6.2(c) or 6.3(c) with respect to a shortfall related to the Liability that gave rise to the Series Indemnified Damages.

Section 7.9 Liability of Indemnitees.

(a) Notwithstanding anything to the contrary set forth in this Agreement, no Indemnitee shall be liable for monetary damages to any Series, any Partner or any other Person who is bound by this Agreement, for losses sustained or liabilities incurred as a result of any act or omission of an Indemnitee unless there has been a final and non-appealable judgment entered by a court of competent jurisdiction determining that, in respect of the matter in question, the Indemnitee acted in bad faith or engaged in fraud, willful misconduct or, in the case of a criminal matter, acted with knowledge that the Indemnitee’s conduct was criminal.

(b) Subject to its obligations and duties as a Managing General Partner set forth in this Agreement, each Managing General Partner may exercise any of the powers granted to it by this Agreement and perform any of the duties imposed upon it hereunder either directly or by or through its agents, and such Managing General Partner shall not be responsible for any misconduct or negligence on the part of any such agent appointed by such Managing General Partner in good faith.

(c) To the extent that, at law or in equity, an Indemnitee has duties (including fiduciary duties) and liabilities relating thereto to the Partnership, any Series or the Partners, the General Partners and any other Indemnitee acting in connection with the Partnership’s or a Series’ business or affairs shall not be liable to the Partnership, such Series or any Partner for its good faith reliance on the provisions of this Agreement. The provisions of this Agreement, to the extent that they restrict or eliminate the duties and liabilities of a Partner or other Person to the parties hereto otherwise existing at law or in equity, are agreed by the parties hereto to replace such other duties and liabilities of such Partner or other Person.

(d) Any amendment, modification or repeal of this Section 7.9 or any provision hereof shall be prospective only and shall not in any way affect the limitations on the liability of the Indemnitees under this Section 7.9 as in effect immediately prior to such amendment, modification or repeal with respect to Claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such Claims may arise or be asserted.

Section 7.10 Limitation of Liability.

The Limited Partners shall have no liability under this Agreement except as expressly provided in this Agreement or the Delaware Act. A General Partner of a Series shall not be liable for the obligations of the Partnership generally or any other Series solely as a result of its status as a General Partner of a Series, and a General Partner of the Partnership generally shall not be liable for the obligations of any Series solely as a result of its status as a General Partner of the Partnership generally.

Section 7.11 Management of Business.

No Limited Partner, in its capacity as such, shall participate in the operation, management or control (within the meaning of the Delaware Act) of the Partnership’s or any Series’ business, transact any business in the Partnership’s or any Series’ name or have the power to sign documents for or otherwise bind the Partnership or any Series. Any action taken by any Affiliate of a General Partner or any officer, director, employee, manager, member, general partner, agent or trustee of a General Partner or any of its Affiliates shall not be deemed to be participation in the control of the business of the Partnership or any Series by a Limited Partner of the Partnership generally or any Series (within the meaning of Section 17-303(a) of the Delaware Act) and shall not affect, impair or eliminate the limitations on the liability of the Limited Partners under this Agreement.

Section 7.12 Outside Activities of the Limited Partners.

Notwithstanding any duty otherwise existing at law or in equity, except as otherwise set forth in any other agreement to which a Partner is a party, including the Omnibus Agreement, any Partner of the Partnership generally or any Series shall be entitled to and may have business interests and engage in business activities in addition to those relating to the Partnership or any Series, including business interests and activities in direct competition with the Partnership or any Series.

Section 7.13 Reliance by Third Parties.

Notwithstanding anything to the contrary in this Agreement, (a) any Person dealing with the Partnership shall be entitled to assume that the Managing General Partner of the Partnership generally, and any officer of such Managing General Partner authorized by such Managing General Partner to act on behalf of and in the name of the Partnership, has full power and authority to encumber, sell or otherwise use in any manner any and all assets of the Partnership generally, and to enter into any authorized contracts on behalf of the Partnership as a whole and the Partnership generally, and such Person shall be entitled to deal with such Managing General Partner or any such officer as if it were the Partnership’s sole party in interest, both legally and beneficially and (b) any Person dealing with any Series shall be entitled to assume that the Managing General Partner of such Series, and any officer of such Managing General Partner authorized by such Managing General Partner to act on behalf of and in the name of such Series, has full power and authority to encumber, sell or otherwise use in any manner any and all assets of such Series and to enter into any authorized contracts on behalf of such Series and such Person shall be entitled to deal with such Managing General Partner or any such officer as if it were such Series’ sole party in interest, both legally and beneficially. Each Limited Partner hereby waives, to the fullest extent permitted by law, any and all defenses or other remedies that may be available against such Person to contest, negate or disaffirm any action of any Managing General Partner or any such officer in connection with any such dealing. In no event shall any Person dealing with any Managing General Partner or any such officer or its representatives be obligated to ascertain that the terms of this Agreement have been complied with or to inquire into the necessity or expedience of any act or action of such Managing General Partner or any such officer or its representatives. Each and every certificate, document or other instrument executed on behalf of the Partnership or any Series by the Managing General Partner of the Partnership

generally or such Series, respectively, or its respective representatives shall be conclusive evidence in favor of any and every Person relying thereon or claiming thereunder that (a) at the time of the execution and delivery of such certificate, document or instrument, this Agreement was in full force and effect, (b) the Person executing and delivering such certificate, document or instrument was duly authorized and empowered to do so for and on behalf of the Partnership or such Series and (c) such certificate, document or instrument was duly executed and delivered in accordance with the terms and provisions of this Agreement and is binding upon the Partnership or such Series, as applicable.

Section 7.14 Managing General Partner.

Except as provided for in Section 10.1, Lakehead GP (or its designee) shall serve as the managing general partner (the “Managing General Partner”) of the Partnership generally and each Series. Except as expressly provided in this Agreement, all management powers over the business and affairs of the Partnership generally or a Series shall be exclusively vested in the Managing General Partner of the Partnership generally or of such Series, as applicable, and no other General Partner nor any Limited Partner shall have any management power over the business and affairs of the Partnership generally or any Series.

Section 7.15 Conflicts of Interest.

Unless otherwise expressly provided herein, (a) whenever a conflict of interest exists or arises between a Managing General Partner or any of its Affiliates, on the one hand, and the Partnership, any Series or any Partner or any Affiliates thereof, on the other hand, or (b) whenever this Agreement or any other agreement contemplated herein provides that a Managing General Partner or any of its Affiliates shall act in a manner that is, or provides terms that are, fair and reasonable to the Partnership or any Partner or any Affiliate thereof, such Managing General Partner shall resolve such conflict of interest, take such action or provide such terms, considering in each case the relative interest of each party (including its own interest) to such conflict, agreement, transaction or situation and the benefits and burdens relating to such interests, any customary or accepted industry practices and any applicable generally accepted accounting practices or principles. In the absence of bad faith by such Managing General Partner, the resolution, action or terms so made, taken or provided by such Managing General Partner shall be permitted and deemed approved by all the Partners and shall not constitute a breach of this Agreement or any other agreement contemplated herein or of any duty, including any fiduciary duty, or obligation of such Managing General Partner at law or in equity or otherwise, and it shall be presumed in making its decision that the Managing General Partner acted in good faith. In any proceeding challenging such decision, the party bringing the challenge shall have the burden of overcoming such presumption.

Section 7.16 Shared Use of Shared Assets.

The Shared Assets shall be shared between the Series AC and the Series LH in accordance with the terms set forth in Exhibit C. Exhibit C is hereby incorporated by reference herein and constitutes an integral, non-severable part of this Agreement.

The Managing General Partner of the Partnership generally and the Managing General Partner of each Series shall keep or cause to be kept full and true books of account maintained in accordance with generally accepted accounting principles consistently applied and in which shall be entered fully and accurately each transaction of the Partnership generally or such Series, as applicable. Such books of account, together with a copy of this Agreement, and of the Certificate of Limited Partnership, shall at all times be maintained at the principal place of business of the Partnership. The records maintained for each Series shall account for the assets associated with each such Series separately from the other assets of the Partnership, if any, or of any other Series. Upon written request, each Partner associated with a Series shall have the right, at a time during ordinary business hours, as reasonably determined by the Managing General Partner of such Series, to inspect and copy, at the requesting Partner’s expense, the records of such Series for any purpose reasonably related to such Partner’s interest with respect to such Series.

In the event the Partnership is required to use a taxable year other than a year ending on December 31, the Managing General Partner of the Partnership generally shall use reasonable efforts to change the taxable year of the Partnership to a year ending on December 31. The tax information reasonably required by Partners for U.S. federal and state income tax reporting purposes with respect to a taxable year shall be furnished to them within 90 days of the close of the calendar year in which the Partnership’s taxable year ends. The classification, realization and recognition of income, gain, losses and deductions and other items shall be on the accrual method of accounting for U.S. federal income tax purposes.

Section 9.2 Partner Tax Return Information.

The Partnership shall cause to be delivered to each Partner within 75 days after the end of the Partnership’s taxable year an IRS Form K-1 or a good faith estimate of the amounts to be included on such IRS Form K-1 for such Partner and such other information as shall be necessary (including a statement for that year of each Partner’s share of net income, net losses and other items allocated to such Partner) for the preparation and timely filing by the Partners of their U.S. federal, state and local income and other tax returns.

Section 9.3 Tax Elections.

(a) If there is a distribution of property of a Series as described in Code Section 734 or a transfer of Partnership Interests as described in Code Section 743, upon request by notice from any Partner of such Series, to elect, pursuant to Code Section 754, to adjust the basis of Series property.

(b) Except as otherwise provided herein, the Managing General Partner of the Partnership generally shall determine whether the Partnership should make any other elections permitted by the Code.

Section 9.4 Tax Controversies.

(a) Subject to the provisions hereof, the Managing General Partner of the Partnership generally is designated as the Tax Matters Partner (as defined in the Code) and is authorized and required to represent the Partnership in connection with all examinations of the Partnership’s affairs by tax authorities, including resulting administrative and judicial proceedings, and to expend funds for professional services and costs associated therewith. Each Partner agrees to cooperate with the Tax Matters Partner and to do or refrain from doing any or all things reasonably required by the Tax Matters Partner to conduct such proceedings.

(b) The Tax Matters Partner shall take such action as may be necessary to cause any Partner so requesting to become a “notice partner” within the meaning of Section 6231(a)(8) of the Code. The Tax Matters Partner shall inform each other Partner of all significant matters that may come to its attention in its capacity as Tax Matters Partner by giving notice thereof on or before the fifth Business Day after becoming aware thereof and, within that time, shall forward to each other Partner copies of all significant written communications it may receive in that capacity. Any cost or expense incurred by the Tax Matters Partner in connection with its duties, including the preparation for or pursuance of administrative or judicial proceedings, shall be paid by the Partnership.

(c) If an audit of any of the Partnership’s tax returns shall occur, the Tax Matters Partner shall not settle or otherwise compromise assertions of the auditing agent that may be adverse to any Partner as compared to the position taken on the Partnership’s tax returns without the prior written consent of each such affected Partner.

(d) No Partner shall file a request pursuant to Code Section 6227 for an administrative adjustment of Partnership items for any taxable year, or a petition under Code Sections 6226 or 6228 or other Code sections with respect to any item involving the Partnership, without first notifying the other Partners. Any Partner that enters into a settlement agreement with respect to any Partnership item (within the meaning of Code Section 6231(a)(3)) shall notify the other Partners of such settlement agreement and its terms within 90 days from the date of the settlement.

(e) If any Partner intends to file a notice of inconsistent treatment under Code Section 6222(b), such Partner shall give reasonable notice under the circumstances to the other Partners of such intent and the manner in which the Partner’s intended treatment of an item is (or may be) inconsistent with the treatment of that item by the other Partners.

Section 9.5 Withholding.

The Managing General Partner of the Partnership generally is authorized to take any action that may be required to cause the Partnership or any Series to comply with any withholding requirements established under the Code or any other federal, state or local law, including pursuant to Sections 1441, 1442, 1445 and 1446 of the Code. To the extent that the Partnership or any Series is required or elects to withhold and pay over to any taxing authority any amount resulting from the allocation or distribution of income to any Partner (including by reason of Section 1446 of the Code), the Managing General Partner of the Partnership generally or of the applicable Series may treat the amount withheld as a distribution of cash pursuant to Section 6.2 or Section 6.3, as applicable, in the amount of such withholding from such Partner.

Section 9.6 Tax Reimbursement.

If Texas law requires the Partnership or a Series and any Partner both to participate in the filing of a Texas franchise tax combined group report, and if such Partner or any other member of the Partner’s combined group pays the franchise tax liability due in connection with such combined report, the parties agree that the Partnership or the applicable Series shall promptly reimburse such Partner for the franchise tax paid on behalf of the Partnership as a combined group member. The franchise tax paid on behalf of the Partnership with respect to each applicable Series shall equal the excess, if any, of (i) the franchise tax that the combined group including the Partnership pays over (ii) the amount the combined group would have paid if it had computed its franchise tax liability for the report period without the Partnership as a member of the combined group, but in no event more than what the Partnership or each applicable Series would have paid had it filed the franchise tax return not as a member of a group. In such event, the parties agree that such Partner shall be considered as paying such amount on behalf of the Partnership with respect to each applicable Series and the Partnership with respect to each applicable Series shall deduct for U.S. federal income tax purposes 100% of the Texas franchise tax attributable to the Partnership with respect to each applicable Series; provided that in the event that such deduction may not be properly taken by the Partnership with respect to each applicable Series, the Partnership with respect to each applicable Series shall reimburse such Partner for the after-tax cost of such payment of Texas franchise tax paid on the Partnership’s behalf.

Section 9.7 Tax Partnership.

It is the intention of the Partners that the Partnership be classified as a partnership for U.S. federal tax purposes. Neither the Partnership nor any Partner shall make an election for the Partnership or any Series to be excluded from the application of the provisions of subchapter K of chapter 1 of subtitle A of the Code or any similar provisions of applicable state or local law or to be classified as other than a partnership pursuant to Treasury Regulation Section 301.7701-3 or any similar provision of state or local law.

Section 9.8 Tax Matters Following a Fundamental Change.

Following the occurrence of a Fundamental Change, the following provisions shall take effect and supersede any conflicting provisions of this Article IX:

(a) EECI Sub shall exercise full and exclusive discretion over all tax matters relating to or affecting the Series AC. For the avoidance of doubt, EECI Sub’s right to exercise its discretion shall include matters relating to the Partnership generally, such as Partnership tax elections permitted by the Code, to the extent that such matter affects the Series AC.

(b) The Partnership shall cause to be delivered to EECI Sub at least 15 Business Days before the due date of any Partnership tax return a copy of the proposed tax return. EECI Sub shall have ten Business Days to request changes to any portions of such tax return that affect Series AC, and the Tax Matters Partner shall make all changes to such tax return requested by EECI Sub prior to timely filing such return.

(c) If an audit of any of the Partnership’s tax returns shall occur, EECI Sub shall have the right, at its discretion, to control all decisions with respect to any matter relating to or affecting the Series AC, and the Tax Matters Partner shall act in accordance with EECI Sub’s direction. For the avoidance of doubt, EECI Sub shall control all decisions with respect to all matters under audit affecting or relating to the Partnership generally to the extent that such matters also affect the Series AC.

ARTICLE X

OTHER EVENTS

Section 10.1 Fundamental Change.

(a) If, at any time, (i) EECI is removed as the general partner of Enbridge Partners pursuant to Section 13.2 (or equivalent provision) of the Fourth Amended and Restated Agreement of Limited Partnership of Enbridge Partners, as amended, or (ii) Enbridge Partners shall cease to directly or indirectly control the Partnership generally and each Series (each, a “Fundamental Change”), then the Managing General Partner of Series AC and each Managing General Partner of any Alberta Clipper Expansion Series shall, without any further action on its part, be deemed to have automatically and irrevocably delegated to EECI Sub (or its designee), to the fullest extent permitted under this Agreement and Delaware law, all of such Managing General Partner’s power and authority to manage and control the business and affairs of the applicable Series (such delegation being referred to herein as the “Maximum Permitted Delegation”), subject to termination only in the sole discretion of EECI Sub. Notwithstanding the delegation provided for in this Section 10.1(a), no Managing General Partner shall be deemed to have withdrawn as a General Partner of the Partnership generally or the applicable Series, and such Managing General Partner shall retain all of its Partnership Interests and Percentage Interests in the Partnership generally and the applicable Series (as the case may be), and none of the foregoing shall be deemed to have been assigned or transferred to EECI Sub (or its designee).

(b) If all or a portion of the Maximum Permitted Delegation is determined to be invalid or unenforceable for any reason following a Fundamental Change, EECI, in its sole discretion, may elect to become the Managing General Partner of the Series AC and each Alberta

Clipper Expansion Series by providing five Business Days’ prior written notice of such election to the Managing General Partner of the Partnership generally at any time (such election, the “Control Option”). Upon exercise of the Control Option:

(i) the Limited Partner Interest of EECI Sub in the Series AC shall automatically convert into a General Partner Interest in the Series AC;

(ii) EECI Sub shall be granted a General Partner Interest in each Alberta Clipper Expansion Series that shall have no economic rights with respect to such Series or otherwise;

(iii) EECI Sub shall automatically become the Managing General Partner of the Series AC and each Alberta Clipper Expansion Series, with all rights, powers and obligations of the Managing General Partner of such Series as set forth in this Agreement; and

(iv) all rights, powers and obligations of the existing Managing General Partner of the Series AC and each Alberta Clipper Expansion Series (in its capacity as such) shall immediately terminate.

The exercise of the Control Option pursuant to this Section 10.1(b) shall not affect (A) the status of any Managing General Partner of the Partnership generally or any Series (other than the Series AC or an Alberta Clipper Expansion Series) or (B) the Percentage Interest of the Series AC Partners or the Partners of any Alberta Clipper Expansion Series.

(c) Following a Fundamental Change, in addition to the rights set forth in Section 9.8 and Section 10.1, EECI, in its sole discretion, may elect to cause the Series AC Assets and the right to operate the assets of each Alberta Clipper Expansion Series to be transferred to the New AC Entity by providing five Business Days’ prior written notice of such election to the Managing General Partner of the Partnership generally at any time (such election, the “Separation Option”). Upon exercise of the Separation Option, the Managing General Partner of the Partnership generally and each Series AC Partner shall (i) negotiate reasonably and in good faith in connection with a transfer of all Series AC Assets and Series AC Liabilities to the New AC Entity and (ii) use their best efforts to (A) effectuate such transfer and (B) allow the newly formed entity to own and operate the Series AC Assets and operate any Alberta Clipper Expansion Projects, including the transfer of all necessary permits, licenses and rights-of-way and the good faith negotiation and performance of any necessary service agreements between the New AC Entity and the Partnership. The Series AC Partners at the time of exercise of the Separation Option shall be the initial partners or members, as applicable, of the New AC Entity, and their relative percentage interest in the New AC Entity shall be proportionate to their Series AC Percentage Interest at the time of exercise of the Separation Option; provided, however, that EECI or its designee shall be the managing general partner, managing member or the equivalent thereof of the New AC Entity. All costs reasonably incurred by the Partnership in complying with this Section 10.1(c) shall be reimbursed by the Series AC.

(d) In connection with the exercise of the Control Option or the Separation Option pursuant to this Section 10.1, each of the Partners agrees to cooperate with respect to such matters and to execute such further assignments, releases, assumptions, amendments of this

Agreement and the Certificate of Limited Partnership, notifications and other documents as may be reasonably requested by EECI, EECI Sub or the Managing General Partner of the Series AC for the purpose of giving effect to, or evidencing or giving notice of, the transactions contemplated by such provisions and the otherwise continued operations of the Partnership.

Section 10.2 Surcharge Expiration.

(a) Upon the expiration or earlier termination of the Surcharge Term, the Tariff Term Sheet shall be replaced with a revised tariff structure in accordance with Section 2(b) of the Tariff Term Sheet (the “Revised Tariff Structure”).

(b) If the Revised Tariff Structure sets forth an objectively determinable definition of (i) the revenue that the Partnership is entitled to collect in tolls and other charges in respect of the Series AC Assets and (ii) the expenses that the Partnership is entitled to allocate in respect of the Series AC Assets, then the Series AC Revenue Entitlement and Series AC Expenses shall be calculated in accordance with the Revised Tariff Structure.

(c) If the Revised Tariff Structure does not set forth an objectively determinable definition of (i) the revenue that the Partnership is entitled to collect in tolls and other charges in respect of the Series AC Assets and (ii) the expenses that the Partnership is entitled to allocate in respect of the Series AC Assets, then EECI Sub and Lakehead GP, on behalf of all Partners of the Partnership generally and each Series, will negotiate in good faith an arrangement to allocate among each Series the total Lakehead System revenue collected by the Partnership following the expiration or earlier termination of the Surcharge Term. Such allocation arrangement will be based on the relative economic value of each Series as of the expiration or earlier termination of the Surcharge Term. If EECI Sub and Lakehead GP are able to agree on such allocation arrangement, then the Series AC Revenue Entitlement and Series AC Expenses will be calculated in accordance with such arrangement. If EECI Sub and Lakehead GP are unable to agree on such allocation arrangement at least 180 days prior to the expiration or earlier termination of the Surcharge Term, then the matter will be submitted to arbitration pursuant to Section 10.2(d).

(d) If the Revised Tariff Structure does not set forth an objectively determinable definition of (i) the revenue that the Partnership is entitled to collect in tolls and other charges in respect of the Series AC Assets and (ii) the expenses that the Partnership is entitled to allocate in respect of the Series AC Assets, and EECI Sub and Lakehead GP are unable to agree on an allocation arrangement pursuant to Section 10.2(c), such allocation arrangement shall be determined through binding arbitration using three arbitrators, in accordance with the Commercial Arbitration Rules of the American Arbitration Association, as supplemented to the extent necessary to determine any procedural appeal questions by the Federal Arbitration Act (Title 9 of the United States Code). If there is any inconsistency between this Section 10.2(d) and the Commercial Arbitration Rules or the Federal Arbitration Act, the terms of this Section 10.2(d) will control the rights and obligations of the parties. Arbitration shall be initiated 180 days prior to the expiration of the Surcharge Term. Each of EECI Sub and Lakehead GP shall appoint an arbitrator at least 150 days prior to the expiration of the Surcharge Term. If either party fails for any reason to name an arbitrator within such period, the other party shall petition to the American Arbitration Association for appointment of an arbitrator for such party’s

account. The two arbitrators so chosen shall select a third arbitrator within 15 days after the second arbitrator has been appointed. Each of EECI Sub and Lakehead GP will pay the compensation and expenses of the arbitrator named by or for it. The costs of petitioning for the appointment of an arbitrator, if any, shall be paid by the party that has failed to appoint an arbitrator in the requisite period. Each of EECI Sub and Lakehead GP will each pay one-half of the compensation and expenses of the third arbitrator. All arbitrators must (a) be neutral Persons who have never been officers, directors or employees of Enbridge Partners, EECI or any of their Affiliates and (b) have not less than seven years experience in the energy industry. The hearing will be conducted in Houston, Texas and commence within 30 days after the selection of the third arbitrator. Within five days after the selection of the third arbitrator, EECI Sub and Lakehead GP shall exchange in writing, signed by the respective parties, their respective proposed allocation arrangements. At the conclusion of the hearing, the arbitrators shall choose either the allocation arrangement of EECI Sub or the allocation arrangement of Lakehead GP, and shall have no power or authority whatsoever to reach any other result. In making their choice, the arbitrators shall choose the allocation arrangement that in their judgment most equitably allocates the total Lakehead System revenues in a manner that best represents the relative economic value of each Series as of the expiration of the Surcharge Term. EECI Sub, Lakehead GP and the arbitrators shall proceed diligently and in good faith in order that the determination may be made as promptly as possible. Except as provided in the Federal Arbitration Act, the decision of the arbitrators will be binding on and non-appealable by the parties.

(iv) at any time that there are no Limited Partners, unless the Partnership is continued without dissolution in accordance with the Delaware Act; or

(v) any event that causes a General Partner to cease to be a general partner of the Partnership generally or any Series; provided that the Partnership shall not be dissolved and required to be wound up in connection with any such event if (A) at the time of the occurrence of such event there is at least one remaining general partner of the Partnership generally or any Series who is hereby authorized to and does carry on the business of the Partnership or (B) within 90 days after the occurrence of such event, a Majority in Interest of the Limited

Partners of each Series agree in writing or vote to continue the business of the Partnership and to the appointment, effective as of the date of such event, if required, of one or more additional general partners of the Partnership generally and, to the extent applicable, each Series.

(b) Upon the dissolution of the Partnership as provided herein, the Partnership shall be wound up by winding up each Series in the manner provided by Section 11.3.

Section 11.2 Termination of a Series.

(a) a Series shall be terminated upon any of the following events:

(i) the dissolution of the Partnership;

(ii) the entry of a decree of judicial termination of such Series under Section 17-218 of the Delaware Act;

(iii) subject to Section 7.3(q), the approval of each General Partner of such Series and a Majority in Interest of the Partnership Interests of such Series; or

(iv) any event that causes a General Partner to cease to be a general partner of the Series; provided that the Series shall not be terminated and required to be wound up in connection with any such event if (A) at the time of the occurrence of such event there is at least one remaining general partner of the Series who is hereby authorized to and does carry on the business of the Series or (B) within 90 days after the occurrence of such event, a Majority in Interest of the Limited Partners of such Series agree in writing or vote to continue the business of the Series and to the appointment, effective as of the date of such event, if required, of one or more additional general partners of the Series.

(b) The termination and winding up of a Series (other than the last Series) shall not, in and of itself, cause a dissolution of the Partnership or the termination of any other Series. The termination of a Series shall not affect the limitation on liabilities of such Series or any other Series provided by this Agreement, the Certificate of Limited Partnership and the Delaware Act.

Section 11.3 Winding Up, Liquidation and Distribution of Assets of the Partnership or a Series Upon Dissolution of the Partnership or Termination of Such Series.

(a) Upon dissolution of the Partnership or termination of a Series, the Managing General Partner of the Partnership generally or of such Series, as applicable, shall commence to wind up the affairs of the Partnership (and all Series) or such Series, as applicable; provided, however, that a reasonable time shall be allowed for the orderly liquidation of the assets of any applicable Series and the discharge of liabilities of the Partnership (and all Series) or such Series, as applicable, to its creditors so as to enable the Partners to minimize the normal losses attendant upon a liquidation. Upon dissolution of the Partnership or termination of a Series after taking into account Regulatory Allocations, all allocations of Profit, Losses and items thereof with respect to a Series shall be made in a manner so that, to the greatest extent possible, the Series Capital Accounts of each Partner in such Series shall equal the amount that would be distributed to such Partner if liquidating distributions were made in accordance with the Partners’ Percentage Interests in such Series. The Partners of each Series being liquidated, as applicable,

shall be furnished with a statement prepared by a certified public accountant selected by the Managing General Partner of the Partnership generally, in its sole discretion, at the expense of such Series, if applicable, that shall set forth the assets and liabilities of the Partnership (and all Series) or such Series (as applicable) as of the date of termination. The proceeds of liquidation shall be distributed in the following order and priority:

(i) to creditors of each applicable Series, including Partners who are creditors, to the extent otherwise permitted by law, in satisfaction (whether by payment or the making of reasonable provision for payment thereof) of all Liabilities of such Series, including, without limitation, the expenses incurred in connection with the liquidation of the Partnership (and all Series) or such Series;

(ii) to the Partners of each Series being liquidated in accordance with such Partners’ Series Capital Account balances for such Series (after giving effect to all contributions, distributions, allocations and other Series Capital Account adjustments for all taxable years, including the year during which such termination and liquidation occurs) in compliance with Treasury Regulation § 1.704-1(b)(2)(ii)(b)(2); and

(iii) if any Limited Partner has a deficit balance in its Series Capital Account for such Series (after giving effect to all contributions, distributions and allocations for all fiscal years, including the fiscal year during which such liquidation occurs), such Limited Partner shall have no obligation to make any contribution to the capital of the Partnership or of such Series with respect to such deficit, and such deficit shall not be considered a debt owed to the Partnership, such Series or to any other Person for any purpose whatsoever.

(b) Notwithstanding any other provisions of this Section 11.3, in the event the Partnership is “liquidated” within the meaning of Treasury Regulation § 1.704-1(b)(2)(ii)(g), but such liquidation does not constitute a dissolution of the Partnership, the assets of the Partnership (and each Series) shall not be liquidated, the liabilities of the Partnership (and each Series) shall not be paid or discharged and the affairs of the Partnership (and each Series) shall not be wound up. Instead, solely for U.S. federal income tax purposes, the Partnership (and each Series) shall be deemed to have distributed all of the assets of the Partnership (and each Series) in kind to a new partnership in exchange for an interest in such new partnership and, immediately thereafter, the Partnership shall be deemed to liquidate by distributing interests in the new partnership to the Partners.

(c) The Managing General Partners and Partners shall comply with all requirements of applicable law pertaining to the winding up of the affairs of the Partnership or any Series and the final distribution of its assets.

Section 11.4 Cancellation of Certificate of Limited Partnership.

Upon the completion of the winding up of the Partnership and each Series and the distribution of Series cash and property as provided in Section 11.3 in connection with the liquidation of the Partnership and each Series, the Certificate of Limited Partnership and all qualifications of the Partnership as a foreign limited partnership in jurisdictions other than the State of Delaware shall be canceled, and such other actions as may be necessary to terminate the Partnership and each Series shall be taken.

Section 11.5 Return of Capital Contributions.

(a) Except as otherwise provided by applicable laws, upon termination of a Series, each Partner of such Series shall look solely to the assets of such Series for the return of its Capital Contributions made to such Series, and if the assets of such Series remaining after satisfaction (whether by payment or reasonable provision for payment) of the Liabilities of such Series are insufficient to return such Capital Contributions, such Partner shall have no recourse against any other Series, the Partnership or any Partner, except as otherwise provided by law or by Section 6.2(c) or 6.3(c).

(b) Except as provided in Section 6.2(c), 6.3(c) or 11.7, no General Partner shall be personally liable for, and shall have no obligation to contribute or loan any monies or property to the Partnership or any Series to enable it to effectuate, the return of the Capital Contributions of the Limited Partners, or any portion thereof, it being expressly understood that any such return shall be made solely from Series assets.

Section 11.6 Waiver of Partition.

To the maximum extent permitted by law, each Partner hereby waives any right to partition of the Partnership or any Series property.

Section 11.7 Capital Account Restoration.

No Limited Partner shall have any obligation to restore any negative balance in its Capital Account or any Series Capital Account upon liquidation of the Partnership or such Series. A General Partner shall be obligated to restore any negative balance in its Capital Account upon liquidation of its interest in the Partnership or any Series by the end of the taxable year of the Partnership during which such liquidation occurs, or, if later, within 90 days after the date of such liquidation.

AMENDMENT OF PARTNERSHIP AGREEMENT;

MEETINGS; RECORD DATE; MERGER

Section 12.1 Amendment.

Except as otherwise provided by this Agreement, this Agreement may be amended by the Managing General Partner of the Partnership generally in writing without the approval of any other Partner; provided that the provisions of Section 7.7 shall not be amended in any way that would adversely affect an Indemnitee without the consent of such Indemnitee.

Section 12.2 Amendment Requirements.

Notwithstanding the provisions of Section 12.1, no provision of this Agreement that establishes a Percentage Interest required to take any action with respect to any Series shall be

amended, altered, changed, repealed or rescinded in any respect that would have the effect of reducing such voting percentage unless such amendment is approved by the written consent or the affirmative vote of holders of Partnership Interests of such Series whose aggregate Percentage Interests constitute not less than the voting requirement sought to be reduced.

Section 12.3 Voting Rights.

Unless otherwise required by the Delaware Act or this Agreement, all actions, approvals and consents to be taken or given by the Partners of a Series under the Delaware Act, this Agreement or otherwise shall require the affirmative vote or written consent of a Majority in Interest of such Series, or if with respect to the Partnership as a whole, the affirmative vote or written consent of a Majority in Interest of each Series.

Section 12.4 Meetings.

Meetings of the Partners of a Series, for any purpose or purposes, may be called by the Managing General Partner of such Series or by any Partner or Partners of such Series holding at least 25% of the Percentage Interests of such Series.

Section 12.5 Place of Meetings.

The Partner or Partners calling a meeting may designate any place, either within or outside the State of Delaware, as the place of meeting for any meeting of the Partners of a Series. If a designation is not made, the place of meeting shall be the principal place of business of the Partnership. The Partners of a Series may participate in a meeting of the Partners of such Series by means of conference telephone or similar communications equipment; provided that all individuals participating in the meeting can hear each other, and such participation in a meeting shall constitute presence in person at such meeting. If all the participants of a meeting are participating by conference telephone or similar communications equipment, the meeting shall be deemed to be held at the principal place of business of the Partnership.

Section 12.6 Notice of Meetings.

Written notice stating the place, day and hour of a meeting and the purpose or purposes for which a meeting of the Partners of a Series is called shall be delivered not less than five nor more than 30 days before the date of the meeting, either personally or by mail, at the direction of the Partner or Partners calling the meeting, to each Partner of such Series entitled to vote at such meeting; provided, however, if the Partners of a Series representing a Majority in Interest of such Series shall meet or participate in a meeting at any time and place, either within or outside the State of Delaware, and consent (whether orally or in writing) to the holding of a meeting at such time, such meeting shall be valid without call or notice, and at such meeting lawful action may be taken.

Section 12.7 Quorum.

Partners of any Series holding a Majority in Interest of such Series entitled to vote, represented in person or by proxy, shall constitute a quorum at any meeting of Partners of such Series. In the absence of a quorum at any such meeting, Partners of such Series holding a

Majority in Interest of such Series may adjourn the meeting from time to time for a period not to exceed 60 days without further notice. However, if the adjournment is for more than 60 days, a notice of the adjourned meeting shall be given to each Partner of such Series of record entitled to vote at such meeting. At such adjourned meeting at which a quorum shall be present or represented, any business may be transacted that might have been transacted at the meeting as originally noticed. The Partners of such Series present at a duly organized meeting may continue to transact business until adjournment, notwithstanding the withdrawal during such meeting of Partners of such Series whose absence would cause less than a quorum to be present. If a quorum is present, the affirmative vote of Partners of such Series holding a Majority in Interest of such Series shall be the act of the Partners of such Series, unless a vote of greater or lesser proportion is otherwise expressly required or permitted by this Agreement.

Section 12.8 Proxies.

At all meetings of Partners of a Series, a Partner of such Series may vote in person or by proxy executed in writing by such Partner or by a duly authorized attorney-in-fact. Such proxy shall be filed with the Partnership before or at the time of the meeting. No proxy shall be valid after eleven months from the date of its execution, unless otherwise provided in the proxy. A proxy may only be given orally during a meeting taking place by conference telephone or similar communications equipment and shall expire at the termination of such meeting.

Section 12.9 Action Without a Meeting.

Any action required or permitted to be taken at a meeting of Partners of any Series may be taken without a meeting and without prior notice if the Managing General Partner of such Series receives written consents by the Partners of such Series representing the minimum number of votes that would be necessary to authorize or to take such action at a meeting at which all Partners of such Series were present and voted.

Section 12.10 Waiver of Notice.

When any notice is required to be given to any Partner, a waiver thereof in writing signed by the Partner entitled to such notice, whether before, at or after the time stated therein, or the presence and participation of such Partner in a meeting, or the participation by such Partner in a meeting by conference telephone or similar communications equipment, shall be equivalent to the giving of such notice.

Section 12.11 Merger, Consolidation and Conversion.

(a) Subject to Section 7.3, the Partnership may merge or consolidate with or into one or more corporations, limited liability companies, statutory trusts or associations, real estate investment trusts, common law trusts or unincorporated businesses, including a partnership (whether general or limited (including a limited liability partnership)) or convert into any such entity, whether such entity is formed under the laws of the State of Delaware or any other state of the United States of America, pursuant to a written plan of merger or consolidation or a written plan of conversion, as the case may be, approved by the Managing General Partner of the Partnership generally and a Majority in Interest of each Series.

(b) Pursuant to Section 17-211(g) of the Delaware Act, an agreement of merger or consolidation approved in accordance with this Section 12.11 may (i) effect any amendment to this Agreement or (ii) effect the adoption of a new partnership agreement for the Partnership. Any such amendment or adoption made pursuant to this Section 12.11 shall be effective at the effective time or date of the merger or consolidation.

(c) The Managing General Partner of the Partnership generally shall have the authority to convert the Partnership to a Delaware statutory trust if, on the advice of counsel, such conversion (i) is necessary and advisable for Wisconsin GP to have or retain condemnation authority under Wisc. Stat. § 32.01, et seq. and (ii) would not result in a default under any Indebtedness of the Partnership or Enbridge Partners existing at such time; provided that (A) the trust is structured as a series trust pursuant to Del. Code tit. 12, § 3801, et seq., (B) the relative rights and obligations of the Partners of each Series are maintained in the trust (and each series thereof), (C) the beneficial owners of each series of the trust own an undivided beneficial interest in all of the assets of the Series of which they are beneficial owners, (D) the trust would be disregarded for U.S. federal income tax purposes and (E) the limited liability of the beneficial owners of the trust (and each series thereof) would be expected to be respected in all relevant states to the same extent as that applicable to limited partners of a Delaware limited partnership.

COVENANTS OF THE PARTIES

(i)

first, to the Series AC or the Series LH, to the extent necessary to address any emergency;

[Exhibit C – Page 3]

(ii)

second, prior to the In-Service Date, to the Series AC, to the extent necessary in connection with the construction of the Alberta Clipper Project; provided that the Series AC’s use of the Shared Assets pursuant to this clause (ii) shall not result in interruptions that could materially and adversely affect the business operations of the Series LH without the consent of the Series LH’s Shared Asset Manager; and

[Exhibit C – Page 4]

(ii)
