The Partners agree that the restrictions contained in this Article IV are fair and reasonable and in the best interests of the Partnership, each Series and the Partners.

(b) Notwithstanding anything herein to the contrary, no Transfer by a Partner of all or any part of its Partnership Interest to another Person shall be permitted unless (i) the transferee agrees in writing to assume the rights and duties of such Partner under this Agreement and to be bound by the provisions of this Agreement and (ii) such transferee shall be admitted to the Partnership as a Partner with respect to the Partnership generally or a Series, as applicable, pursuant to Section 4.1(c) immediately prior to the transferor ceasing to be a Partner with respect to the transferred portion of the Partnership Interest, and the business of the Partnership and each Series shall continue without dissolution or termination, respectively.

(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 Agreement and, if required by law, the Managing General Partner of the Partnership generally shall prepare and file an amendment to the Certificate of Limited Partnership. The transferee shall be admitted to the Partnership with respect to the Partnership generally or the applicable Series, as the case may be, as a general partner or limited partner, as applicable, upon satisfaction of the requirements of Section 4.1(b) and this Section 4.1(c), without the consent of any other Partner being required.

(d) No Partner shall have any right to withdraw from the Partnership or any Series; provided, however, that when a transferee of a Partner’s Partnership Interest is admitted to the Partnership or any Series in accordance with Section 4.1(c) with respect to the Partnership Interest so transferred, the transferring Partner shall cease to be a Partner with respect to the Partnership Interest so transferred.

Section 4.2 General Restrictions on Transfers of Partnership Interests.

(a) Notwithstanding the other provisions of this Article IV, no Transfer of any Partnership Interests shall be made if such Transfer would (i) violate the then applicable federal or state securities laws or rules and regulations of the Commission, any state securities commission or any other governmental authority with jurisdiction over such Transfer, (ii) terminate the existence or qualification of the Partnership or any Series under the laws of the State of Delaware or (iii) cause the Partnership or any Series to be treated as an association taxable as a corporation or otherwise to be taxed as an entity for U.S. federal income tax purposes (to the extent not already so treated or taxed).

(b) The Managing General Partner of the Partnership generally may impose restrictions on the Transfer of Partnership Interests if it receives an opinion of counsel that such restrictions are necessary to avoid a significant risk of the Partnership or any Series becoming taxable as a corporation or otherwise becoming taxable as an entity for U.S. federal income tax purposes. Notwithstanding Sections 12.1 and 12.2, the Managing General Partner of the Partnership generally may impose such restrictions by amending this Agreement.

(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.

Section 4.3 Additional Restrictions on Transfers of Partnership Interests.

(a) Series EA and Series ME Partnership Interests. No Transfer of a Series EA or Series ME Partnership Interest may be made unless (i) such Transfer complies with the provisions of Section 4.1 and Section 4.2 and (ii) unless such Transfer is to a Permitted Transferee of the transferring Partner, such Transfer is made in accordance with Sections 4.5, 4.6 or 4.7, as applicable.

(b) Series LH Partnership Interests. No Transfer of a Series LH or Series AC Partnership Interest may be made unless such Transfer complies with the provisions of Section 4.1 and Section 4.2.

Section 4.4 Reserved.

Section 4.5 Series EA Right of First Refusal.

(a) If any Partner receives a bona fide written offer from a Third Party (a “Third Party Offer”) for the Transfer of all or a part of such Partner’s (and its respective Permitted Transferees) Partnership Interests in Series EA and such Partner (the “EA Offering Partner”) desires to accept and is otherwise permitted to effect such proposed Transfer pursuant to this Article IV, such EA Offering Partner shall deliver written notice of such Third Party Offer (the “EA ROFR Notice”) to the Managing General Partner of the Partnership generally as soon as reasonably practicable, but in no event less than 35 days prior to the date of the proposed Transfer. The date that the EA ROFR Notice is received by the Managing General Partner of the Partnership generally shall constitute the “EA ROFR Notice Date.” Within five Business Days following the EA ROFR Notice Date, the Managing General Partner of the Partnership generally shall send a copy of the EA ROFR Notice along with a letter indicating the EA ROFR Notice Date to EECI and Enbridge Partners (each, a “ROFR Holder” and collectively, the “ROFR Holders”). The EA ROFR Notice shall set forth the identity of the Third Party (including, (x) if such information is not publicly available, information about the identity of the Third Party, (y) the identity of Affiliates of the Third Party and (z) if the Third Party is making the Third Party Offer as a nominee of another Person, the identity of such other Person and its Affiliates), the amount and the Partnership Interests to be sold (the “EA Offered Interests”), the proposed purchase price for the EA Offered Interests (the “EA ROFR 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 EA 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 EA Offered Interests equal to the product of (i) the amount of the EA Offered Interests and (ii) a fraction (the “EA ROFR Proportionate Share”), the numerator of which shall be the Series EA Percentage Interest of such ROFR Holder and the denominator of which shall be the sum of the Series EA Percentage Interests held by the ROFR Holders. Within 25 days after the EA ROFR Notice Date, each ROFR Holder may deliver a written notice to the EA Offering Partner, the Managing General Partner of the Partnership generally and the other EA ROFR Holder of its election to purchase such EA 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 a ROFR Holder does not elect to purchase its full EA ROFR Proportionate Share of such EA Offered Interests, the other ROFR Holder, if it has elected to purchase its full EA ROFR Proportionate Share, shall be entitled, by delivering written notice to the EA 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 “EA ROFR Expiration Date”), to purchase up to all of the remaining EA Offered Interests. The delivery of a notice of election under this Section 4.5(b) shall constitute an irrevocable commitment to purchase such EA Offered Interests. If the ROFR Holders shall have elected to purchase all but not less than all of the EA 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 EA Offered Interests, which shall be not less than 10 days nor more than 60 days after the EA 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 EA Offered Interests pursuant to this Section 4.5 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 EA ROFR Offer Price and shall be payable in immediately available U.S. dollars; and provided further that the EA Offering Partner shall at a minimum make customary representations and warranties concerning (i) such EA Offering Partner’s valid title to and ownership of the EA Offered Interests, free and clear of all liens, claims and encumbrances (excluding those arising hereunder and under applicable securities laws), (ii) such EA Offering Partner’s authority, power and right to enter into and consummate the sale of the EA Offered Interests, (iii) the absence of any violation, default or acceleration of any agreement or obligation to which such EA Offering Partner is subject or by which its assets are bound as a result of the sale of the EA 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 EA Offering Partner in connection with the sale of the EA Offered Interests. The EA Offering Partner and participating ROFR Holders shall use commercially reasonable efforts to close the purchase of the EA Offered Interests as soon as reasonably practicable following the EA 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 EA Offered Interests hereunder.

(d) Notwithstanding the foregoing, if (i) the ROFR Holders (A) shall have elected to purchase less than all of the EA Offered Interests or (B) shall not have elected to purchase any of the EA Offered Interests on or prior to the EA ROFR Expiration Date, and the EA Offering Partner has fully complied with the provisions of this Section 4.5, then the EA Offering Partner may sell all, but not less than all, of the EA Offered Interests within 90 days after the EA 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 4.5(b) (such period, the “EA ROFR Closing Period”) and the EA Offering Partner has fully complied with the provisions of this Section 4.5, then the EA Offering Partner may sell all, but not less than all, of the EA Offered Interests within 90 days after the expiration of the EA 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 EA Offered Interests are not so transferred within the applicable time periods specified in this Section 4.5(d), the EA Offering Partner may not sell any of the EA 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 EA Offered Interests pursuant to this Section 4.5 to any of its Permitted Transferees.

(f) This Section 4.5 shall not apply to any Transfer or proposed Transfer of Partnership Interests to a Permitted Transferee.

Section 4.6 Series ME Right of First Refusal.

(a) If any Partner receives a Third Party Offer for the Transfer of all or a part of such Partner’s (and its respective Permitted Transferees) Partnership Interests in Series ME and such Partner (the “ME Offering Partner”) desires to accept and is otherwise permitted to effect such proposed Transfer pursuant to this Article IV, such ME Offering Partner shall deliver written notice of such Third Party Offer (the “ME ROFR Notice”) to the Managing General Partner of the Partnership generally as soon as reasonably practicable, but in no event less than 35 days prior to the date of the proposed Transfer. The date that the ME ROFR Notice is received by the Managing General Partner of the Partnership generally shall constitute the “ME ROFR Notice Date.” Within five Business Days following the ME ROFR Notice Date, the Managing General Partner of the Partnership generally shall send a copy of the ME ROFR Notice along with a letter indicating the ME ROFR Notice Date to the ROFR Holders. The ME ROFR Notice shall set forth the identity of the Third Party (including, (x) if such information is not publicly available, information about the identity of the Third Party, (y) the identity of Affiliates of the Third Party and (z) if the Third Party is making the Third Party Offer as a nominee of another Person, the identity of such other Person and its Affiliates), the amount and the Partnership Interests to be sold (the “ME Offered Interests”), the proposed purchase price for the ME Offered Interests (the “ME ROFR 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 ME 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 ME Offered Interests equal to the product of (i) the amount of the ME Offered Interests and (ii) a fraction (the “ME ROFR Proportionate Share”), the numerator of which shall be the Series ME Percentage Interest of such ROFR Holder and the denominator of which shall be the sum of the Series ME Percentage Interests held by the ROFR Holders. Within 25 days after the ME ROFR Notice Date, each ROFR Holder may deliver a written notice to the ME Offering Partner, the Managing General Partner of the Partnership generally and the other ME ROFR Holder of its election to purchase such ME 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 a ROFR Holder does not elect to purchase its full ME ROFR Proportionate Share of such ME Offered Interests, the other ROFR Holder, if it has elected to purchase its full ME ROFR Proportionate Share, shall be entitled, by delivering written notice to the ME 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 “ME ROFR Expiration Date”), to purchase up to all of the remaining ME Offered Interests. The delivery of a notice of election under this Section 4.6(b) shall constitute

an irrevocable commitment to purchase such ME Offered Interests. If the ROFR Holders shall have elected to purchase all but not less than all of the ME 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 ME Offered Interests, which shall be not less than 10 days nor more than 60 days after the ME 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 ME Offered Interests pursuant to this Section 4.6 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 ME ROFR Offer Price and shall be payable in immediately available U.S. dollars; and provided further that the ME Offering Partner shall at a minimum make customary representations and warranties concerning (i) such ME Offering Partner’s valid title to and ownership of the ME Offered Interests, free and clear of all liens, claims and encumbrances (excluding those arising hereunder and under applicable securities laws), (ii) such ME Offering Partner’s authority, power and right to enter into and consummate the sale of the ME Offered Interests, (iii) the absence of any violation, default or acceleration of any agreement or obligation to which such ME Offering Partner is subject or by which its assets are bound as a result of the sale of the ME 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 ME Offering Partner in connection with the sale of the ME Offered Interests. The ME Offering Partner and participating ROFR Holders shall use commercially reasonable efforts to close the purchase of the ME Offered Interests as soon as reasonably practicable following the ME 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 ME Offered Interests hereunder.

(d) Notwithstanding the foregoing, if (i) the ROFR Holders (A) shall have elected to purchase less than all of the ME Offered Interests or (B) shall not have elected to purchase any of the ME Offered Interests on or prior to the ME ROFR Expiration Date, and the ME Offering Partner has fully complied with the provisions of this Section 4.6, then the ME Offering Partner may sell all, but not less than all, of the ME Offered Interests within 90 days after the ME 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 4.6(b) (such period, the “ME ROFR Closing Period”) and the ME Offering Partner has fully complied with the provisions of this Section 4.6, then the ME Offering Partner may sell all, but not less than all, of the ME Offered Interests within 90 days after the expiration of the ME 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 ME Offered Interests are not so transferred within the applicable time periods specified in this Section 4.6(d), the ME Offering Partner may not sell any of the ME 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 ME Offered Interests 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 Partnership Interests to a Permitted Transferee.

Section 4.7 Tag-Along Rights.

(a) If a Series EA Partner or Series ME Partner (the “Transferor”) proposes to Transfer all or a part of its Partnership Interests in Series EA or Series ME 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 Partners of the Series of Partnership Interests which such Transferor proposes to Transfer (the “Tag Offerees”) at least 30 days prior to effecting such Transfer. Such Tag-Along Notice may be combined with an EA ROFR Notice or ME ROFR Notice and may be conditioned upon the ROFR Holders not exercising the right of first refusal contained in Section 4.5 or Section 4.6. 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 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 Partnership Interests in Series EA or Series ME, as applicable, 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 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 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 Partnership Interests that each otherwise would have sold so as to permit the Transferor and the exercising Tag Offerees to sell the portion of 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 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 applicable Series and the Managing General Partner of the Partnership generally to cooperate fully with potential acquirors of its 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 4.8 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 4.8, 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 4.8 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 4.8 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 4.8, 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 4.8(b) (such period, the “ROFR Asset Closing Period”) and the Series has fully complied with the provisions of this Section 4.8, 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, Section 7.4 and Section 7.5, as applicable. 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 4.8(d), the Series may not sell the ROFR Offered Asset without again complying in full with the provisions of this Section 4.8.

(e) EECI shall be entitled to assign any rights it has to purchase a ROFR Offered Asset pursuant to this Section 4.8 to any of its Permitted Transferees.

(f) This Section 4.8 shall not apply to any transfer or proposed transfer of assets to a Permitted Transferee.

Section 4.9 EA Call Option.

(a) From time to time prior to the twelve-month anniversary of the Eastern Access Final In-Service Date (the “EA Call Option Deadline”), Enbridge Partners shall have the right to purchase, and EECI shall have the obligation to sell (the “EA Call Option”), a portion of the Series EA Limited Partner Interests held by EECI that represents, in the aggregate, up to fifteen percent (15%) of the total outstanding Series EA Partnership Interests in accordance with this Section 4.9. In considering whether to exercise the EA Call Option, the Board of Directors of Enbridge Energy Management, L.L.C. (the “EEM Board”) shall establish a committee of independent directors (an “Option Committee”) to make a recommendation to the EEM Board, on behalf of Enbridge Partners, whether to exercise the EA Call Option and the portion of Series EA Limited Partner Interests held by EECI that Enbridge Partners will purchase if the EA Call Option is exercised (not to exceed, in the aggregate, fifteen (15%) of the total outstanding Series EA Partnership Interests). The general partner of Enbridge Partners and the Managing General Partner of the Partnership and of each Series shall provide the Option Committee with all of the information that the Option Committee may reasonably request that is relevant to its determination.

(b) If the EEM Board determines to exercise all or a portion of the EA Call Option following receipt of the Option Committee’s recommendation, Enbridge Partners shall deliver to the Partnership and to EECI, prior to the EA Call Option Deadline, written notice (each, an “EA Call Option Notice”) of such determination. Each EA Call Option Notice shall state (i) the portion of the Series EA Limited Partner Interests held by EECI proposed to be purchased (not to exceed, in the aggregate, fifteen percent (15%) of the total outstanding Series EA Partnership Interests) (an “EA Call Option Interest”) and the corresponding amount of consideration to be paid, calculated in accordance with Section 4.9(c), (ii) the proposed date of purchase and (iii) other proposed material terms and conditions of such sale. Upon receipt of each EA Call Option Notice, EECI agrees to promptly take all necessary and desirable actions in connection with the exercise of the EA Call Option reasonably requested by Enbridge Partners, including the execution of such agreements and such instruments and other actions reasonably necessary to

consummate the purchase and sale of the EA Call Option Interest hereunder. Each date on which the purchase and sale of an EA Call Option Interest is consummated is referred to as an “EA Call Option Closing Date.” Such agreements and instruments shall contain customary representations and warranties concerning (i) EECI’s valid title to and ownership of the EA Call Option Interest, free and clear of all liens, claims and encumbrances (excluding those arising under this Agreement and applicable securities laws), (ii) EECI’s authority, power and right to enter into and consummate the sale of the EA Call Option Interest, (iii) the absence of any violation, default or acceleration of any agreement to which EECI is subject or by which its Partnership Interests are bound as a result of the agreement to sell and the sale of the EA Call Option Interest, 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 EECI in connection with the sale of the EA Call Option Interest. EECI 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 Enbridge Partners may reasonably request, but neither the failure of EECI to execute or deliver any such documentation nor the failure of EECI to comply with all required actions shall affect the validity of a purchase and sale pursuant to this Section 4.9.

(c) The purchase price to be paid by Enbridge Partners to EECI for the purchase of an EA Call Option Interest shall equal the capital contributed by EECI in respect of such EA Call Option Interest, plus the product of (i) the AFUDC attributable to the Eastern Access Project, less depreciation attributable to the Eastern Access Project, in each case, for the period from the Series EA Closing Date through the applicable EA Call Option Closing Date, and (ii) the quotient, expressed as a percentage, obtained by dividing the EA Call Option Interest by the total outstanding Series EA Partnership Interests. For illustrative purposes, an example of this calculation methodology is attached hereto as Exhibit F.

Section 4.11 ME Call Option.

(a) From time to time prior to the twelve-month anniversary of (i) the Mainline Expansion Final In-Service Date, if Mainline Expansion Phase IV has been approved by XXXX as of the Mainline Expansion Phase III In-Service Date, or (ii) the Mainline Expansion Phase III

In-Service Date, if Mainline Expansion Phase IV has been not been approved by XXXX as of the Mainline Expansion Phase III In-Service Date (the “ME Call Option Deadline”), Enbridge Partners shall have the right to purchase, and EECI shall have the obligation to sell (the “ME Call Option”), a portion of the Series ME Limited Partner Interests held by EECI that represents, in the aggregate, up to fifteen percent (15%) of the total outstanding Series ME Partnership Interests in accordance with this Section 4.11. In considering whether to exercise the ME Call Option, the EEM Board shall establish an Option Committee to make a recommendation to the EEM Board, on behalf of Enbridge Partners, whether to exercise the ME Call Option and the portion of Series ME Limited Partner Interests held by EECI that Enbridge Partners will purchase if the ME Call Option is exercised (not to exceed, in the aggregate, fifteen (15%) of the total outstanding Series ME Partnership Interests). The general partner of Enbridge Partners and the Managing General Partner of the Partnership generally and of each Series shall provide the Option Committee with all of the information that the Option Committee may reasonably request that is relevant to its determination.

(b) If the EEM Board determines to exercise all or a portion of the ME Call Option following receipt of the Option Committee’s recommendation, Enbridge Partners shall deliver to the Partnership and to EECI, prior to the ME Call Option Deadline, written notice (each, a “ME Call Option Notice”) of such determination. Each ME Call Option Notice shall state (i) the portion of the Series ME Limited Partner Interests held by EECI proposed to be purchased (not to exceed, in the aggregate, fifteen percent (15%) of the total outstanding Series ME Partnership Interests) (a “ME Call Option Interest”) and the corresponding amount of consideration to be paid, calculated in accordance with Section 4.11(c), (ii) the proposed date of purchase and (iii) other proposed material terms and conditions of such sale. Upon receipt of each ME Call Option Notice, EECI agrees to promptly take all necessary and desirable actions in connection with the exercise of the ME Call Option reasonably requested by Enbridge Partners, including the execution of such agreements and such instruments and other actions reasonably necessary to consummate the purchase and sale of the ME Call Option Interest hereunder. Each date on which the purchase and sale of a ME Call Option Interest is consummated is referred to as a “ME Call Option Closing Date.” Such agreements and instruments shall contain customary representations and warranties concerning (i) EECI’s valid title to and ownership of the ME Call Option Interest, free and clear of all liens, claims and encumbrances (excluding those arising under this Agreement and applicable securities laws), (ii) EECI’s authority, power and right to enter into and consummate the sale of the ME Call Option Interest, (iii) the absence of any violation, default or acceleration of any agreement to which EECI is subject or by which its Partnership Interests are bound as a result of the agreement to sell and the sale of the ME Call Option Interest, 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 EECI in connection with the sale of the ME Call Option Interest. EECI 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 Enbridge Partners may reasonably request, but neither the failure of EECI to execute or deliver any such documentation nor the failure of EECI to comply with all required actions shall affect the validity of a purchase and sale pursuant to this Section 4.11.

(c) The purchase price to be paid by Enbridge Partners to EECI for the purchase of a ME Call Option Interest shall equal the capital contributed by EECI in respect of such ME Call

Option Interest, plus the product of (i) the AFUDC attributable to the Mainline Expansion Project, less depreciation attributable to the Mainline Expansion Project, in each case, for the period from the Series ME Closing Date through the applicable ME Call Option Closing Date, and (ii) the quotient, expressed as a percentage, obtained by dividing the ME Call Option Interest by the total outstanding Series ME Partnership Interests. For illustrative purposes, an example of this calculation methodology is attached hereto as Exhibit F.

(d) If and to the extent that any distributions accruing on a ME Call Option Interest that are attributable to the operations of the Series ME prior to the applicable ME Call Option Closing Date are declared or paid on or after such ME Call Option Closing Date, EECI shall be entitled to receive, and the Partnership shall pay to EECI, subject to the Delaware Act, (i) with respect to a Quarter ending prior to the Quarter in which the ME Call Option Closing Date occurs for which distributions on the Series ME Partnership Interests have not been declared and/or paid as of the ME Call Option Closing Date, an amount equal to the distributions attributable to the ME Call Option Interest with respect to such Quarter and (ii) with respect to a Quarter in which the ME Call Option Closing Date occurs, an amount equal to the product of (x) the distributions attributable to the ME Call Option Interest with respect to such Quarter and (y) the quotient obtained by dividing the number of days the ME Call Option Interest was held by EECI during such Quarter by the total number of days in such Quarter.

Section 5.6 Additional Series EA Capital Contributions.

(a) Each Series EA Partner hereby agrees to make additional Capital Contributions to the Series EA (the “Additional Series EA Capital Contributions”) in proportion to such Series EA Partner’s Series EA Percentage Interest at such times and in such amounts as the Managing General Partner of the Series EA shall specify in a notice delivered to the Series EA Partners pursuant to Section 5.6(b) or Section 5.6(c) (“Series EA Capital Contribution Notice”); provided that in no event shall any Series EA Partner be required to make, in the aggregate, Capital Contributions in excess of such Series EA Partner’s respective Maximum Commitment with respect to Series EA set forth on Exhibit A. All Additional Series EA Capital Contributions shall be contributed to the Series EA in immediately available U.S. dollars on the date specified in the applicable Series EA Capital Contribution Notice. No Series EA Partner shall be required to make any Additional Series EA Capital Contribution, or to otherwise contribute any amount, to the Series EA unless such Additional Series EA Capital Contribution is reflected on the Series EA Annual Budget for such fiscal year or is otherwise approved by the Managing General Partner of the Series EA and a Supermajority Interest of Series EA Partnership Interests.

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

(c) From time to time following the Eastern Access Final In-Service Date, the Managing General Partner of the Series EA may deliver to the Series EA Partners a Series EA Capital Contribution Notice related to amounts that the Managing General Partner of the Series EA determines are necessary to fund the Series EA’s operations and establish reasonable reserves in respect of the Series EA’s expenses. Such notice shall set forth (i) the manner in which, and the expected date on which, such Additional Series EA Capital Contribution is to be applied, (ii) the amount of the required Additional Series EA Capital Contribution to be made by such Series EA Partner, which shall be an amount equal to such Series EA Partner’s Pro Rata portion of the total amount of such Additional Series EA Capital Contribution, (iii) the date on which such Additional Series EA 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 EA Capital Contribution is to be made.

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

(e) If a Series EA Partner fails to fund all or any portion of its required Additional Series EA Capital Contribution set forth in a Series EA Capital Contribution Notice and fails to cure such default within five Business Days after the due date set forth in such Series EA Capital Contribution Notice (the “Default Series EA Capital Contribution”), the Series EA Partner failing to make such contribution (the “Defaulting Series EA Partner”) will be in default. Upon the occurrence of any such default, the Managing General Partner of Series EA shall promptly notify the Defaulting Series EA Partner and the other Series EA Partners not in default (each a “Non-Defaulting Series EA Partner”) of the occurrence of such default. As long as a Default Series EA Capital Contribution remains unpaid or arrangements for the payment thereof have not been agreed to by the Series EA Partners, any Non-Defaulting Series EA Partner may advance to the Series EA the entire amount of the Defaulting Series EA Partner’s Capital Contribution that has not been contributed, with each Non-Defaulting Series EA Partner electing to participate in such advance making its share of such advance in proportion to its Series EA Percentage Interest (without taking into account the Series EA Percentage Interest of the Defaulting Series EA Partner). Each Non-Defaulting Series EA Partner who makes such an advance on behalf of a Defaulting Series EA Partner will have the right to elect the extent to which such advance will (x) constitute a loan to the Defaulting Series EA Partner and/or (y) be treated as a Capital Contribution by such Non-Defaulting Series EA Partner and result in an immediate adjustment of the Series EA Percentage Interests of the Defaulting Series EA Partner and the Non-Defaulting Series EA Partner making such election in accordance with Section 5.6(e)(i); provided, however, that if the advancing Non-Defaulting Series EA Partner does not notify the Managing General Partner of the Series EA of its election to have all, or any portion of, such advance treated as a loan to the Defaulting Series EA 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 EA Percentage Interests.

(i) To the extent that one or more Non-Defaulting Series EA Partners do not elect to have an advance made pursuant to this Section 5.6(e) treated as a loan to the Defaulting

Series EA Partner, or affirmatively elects to have such advance treated as a Capital Contribution, the Managing General Partner of the Series EA will automatically adjust the Series EA Percentage Interest of (A) each such Non-Defaulting Series EA Partner to equal the percentage obtained by dividing (x) the Series EA Capital Account of each such Non-Defaulting Series EA Partner (including any Capital Contribution made by such Non-Defaulting Series EA Partner under this Section 5.6(e) multiplied by three) by (y) the sum of the Series EA Capital Accounts of all Series EA Partners (including all Capital Contributions made under this Section 5.6(e) multiplied by three) and (B) such Defaulting Series EA Partner to equal the amount of (x) such Defaulting Series EA Partner’s Series EA Percentage Interest immediately prior to the occurrence of such default less (y) the aggregate increases to the Series EA Percentage Interests of Non-Defaulting Series EA Partners pursuant to clause (A). Notwithstanding the foregoing, the Defaulting Series EA Partner will have the right to re-acquire the interest in question from any advancing Non-Defaulting Series EA Partner within 30 days following the date on which such Series EA Percentage Interest adjustment is made by paying the entire amount advanced by such Non-Defaulting Series EA 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, (B) 12% per annum or (C) in the case of an advance from EECI or its Affiliates to Enbridge Partners or its Subsidiaries, the rate that would be charged Enbridge Partners by unrelated lenders on a comparable loan, whereupon the Series EA Percentage Interests of each Series EA Partner shall be adjusted to equal the Percentage Interest such Series EA Partner would have had in the absence of a default by such Defaulting Series EA Partner.

(ii) To the extent one or more Non-Defaulting Series EA Partners (each, a “Lending Series EA Partner”) elects to have an advance made pursuant to this Section 5.6(e) constitute a loan to the Defaulting Series EA Partner, such advance will have the following results (except to the extent otherwise agreed by the Lending Series EA Partner and the Defaulting Series EA Partner, each in their sole discretion):

(A) the sum advanced will constitute a loan from the Lending Series EA Partner to the Defaulting Series EA Partner and an Additional Series EA Capital Contribution of that sum to the Series EA by the Defaulting Series EA 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 EA 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 EA Partner Obligation is made by the Lending Series EA Partner to the Defaulting Series EA Partner; provided, however, that the Defaulting Series EA Partner may prepay the Defaulting Series EA Partner Obligation in whole or in part at any time prior to the date due;

(C) the amount lent will bear interest at the rate that is the lesser of (A) the maximum, lawful interest rate, compounded monthly, that is then-currently permitted under applicable law, (B) 12% per annum or (C) in the case of an advance from EECI or its Affiliates to Enbridge Partners or its Subsidiaries, the rate that would be charged Enbridge Partners by unrelated lenders on a comparable loan;

(D) the Lending Series EA 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 EA Partner may deem appropriate to obtain payment from the Defaulting Series EA Partner of the Defaulting Series EA Partner Obligation; and

(E) initially, a loan by a Lending Series EA Partner to a Defaulting Series EA Partner as contemplated by this Section 5.6(e)(ii) will not be considered a Capital Contribution by such Lending Series EA Partner and will not increase the Capital Account balance of such Lending Series EA 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 EA Partner, at any time thereafter by giving written notice to the Managing General Partner of the Series EA and the Defaulting Series EA Partner, may elect to have an amount equal to the unpaid principal and interest balance of such loan transferred from such Defaulting Series EA Partner’s Capital Account to such Lending Series EA Partner’s Capital Account and increase such Lending Series EA Partner’s Capital Account with a corresponding decrease in such Defaulting Series EA Partner’s Capital Account. Upon such transfer, the loan will be treated as a Capital Contribution and the Series EA Percentage Interest for (A) such Lending Series EA Partner will be automatically adjusted to equal the percentage obtained by dividing (x) the Capital Account of such Lending Series EA Partner (including any Capital Contribution made by such Lending Series EA Partner under this Section 5.6(e)(ii)(E) on behalf of the Defaulting Series EA Partner multiplied by three) by (y) the sum of the Series EA Capital Accounts of all Series EA Partners (including all Capital Contributions made under this Section 5.6(e)(ii)(E) on behalf of the Defaulting Series EA Partner multiplied by three) and (B) such Defaulting Series EA Partner will be automatically adjusted to equal the amount of (x) such Defaulting Series EA Partner’s Series EA Percentage Interest immediately prior to such election by the Lending Series EA Partner less (y) the increase to the Series EA Percentage Interest of Lending Series EA Partner pursuant to clause (A).

(f) Notwithstanding the rights of Non-Defaulting Series EA Partners described in Section 5.6(e), the Managing General Partner of the Series EA, by a vote of a Supermajority Interest of Series EA Partnership Interests (without taking into account the Series EA Partnership Interests of the Defaulting Series EA Partner), will have the right to exercise any rights and remedies available at law or in equity.

Section 5.7 Initial Series ME Capital Contributions.

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

(b) On the Series ME Closing Date, the Managing General Partner of Series ME applied the proceeds of the Initial Series ME Capital Contributions to repay the Intercompany Preliminary ME Construction Cost Payable.

The Percentage Interests of each Series ME General Partner and Series ME Limited Partner as of the date of this Agreement are as set forth on Exhibit A.

Section 5.8 Additional Series ME Capital Contributions.

(a) Each Series ME Partner hereby agrees to make additional Capital Contributions to the Series ME (the “Additional Series ME Capital Contributions”) in proportion to such Series ME Partner’s Series ME Percentage Interest at such times and in such amounts as the Managing General Partner of the Series ME shall specify in a notice delivered to the Series ME Partners pursuant to Section 5.8(b) or Section 5.8(c) (“Series ME Capital Contribution Notice”); provided that in no event shall any Series ME Partner be required to make, in the aggregate, Capital Contributions in excess of such Series ME Partner’s respective Maximum Commitment with respect to Series ME set forth on Exhibit A. All Additional Series ME Capital Contributions shall be contributed to the Series ME in immediately available U.S. dollars on the date specified in the applicable Series ME Capital Contribution Notice. No Series ME Partner shall be required to make any Additional Series ME Capital Contribution, or to otherwise contribute any amount, to the Series ME unless such Additional Series ME Capital Contribution is reflected on the Series ME Annual Budget for such fiscal year or is otherwise approved by the Managing General Partner of the Series ME and a Supermajority Interest of Series ME Partnership Interests.

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

(c) From time to time following the Mainline Expansion Final In-Service Date, the Managing General Partner of the Series ME may deliver to the Series ME Partners a Series ME Capital Contribution Notice related to amounts that the Managing General Partner of the Series ME determines are necessary to fund the Series ME’s operations and establish reasonable reserves in respect of the Series ME’s expenses. Such notice shall set forth (i) the manner in

which, and the expected date on which, such Additional Series ME Capital Contribution is to be applied, (ii) the amount of the required Additional Series ME Capital Contribution to be made by such Series ME Partner, which shall be an amount equal to such Series ME Partner’s Pro Rata portion of the total amount of such Additional Series ME Capital Contribution, (iii) the date on which such Additional Series ME 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 ME Capital Contribution is to be made.

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

(e) If a Series ME Partner fails to fund all or any portion of its required Additional Series ME Capital Contribution set forth in a Series ME Capital Contribution Notice and fails to cure such default within five Business Days after the due date set forth in such Series ME Capital Contribution Notice (the “Default Series ME Capital Contribution”), the Series ME Partner failing to make such contribution (the “Defaulting Series ME Partner”) will be in default. Upon the occurrence of any such default, the Managing General Partner of Series ME shall promptly notify the Defaulting Series ME Partner and the other Series ME Partners not in default (each a “Non-Defaulting Series ME Partner”) of the occurrence of such default. As long as a Default Series ME Capital Contribution remains unpaid or arrangements for the payment thereof have not been agreed to by the Series ME Partners, any Non-Defaulting Series ME Partner may advance to the Series ME the entire amount of the Defaulting Series ME Partner’s Capital Contribution that has not been contributed, with each Non-Defaulting Series ME Partner electing to participate in such advance making its share of such advance in proportion to its Series ME Percentage Interest (without taking into account the Series ME Percentage Interest of the Defaulting Series ME Partner). Each Non-Defaulting Series ME Partner who makes such an advance on behalf of a Defaulting Series ME Partner will have the right to elect the extent to which such advance will (x) constitute a loan to the Defaulting Series ME Partner and/or (y) be treated as a Capital Contribution by such Non-Defaulting Series ME Partner and result in an immediate adjustment of the Series ME Percentage Interests of the Defaulting Series ME Partner and the Non-Defaulting Series ME Partner making such election in accordance with Section 5.8(e)(i); provided, however, that if the advancing Non-Defaulting Series ME Partner does not notify the Managing General Partner of the Series ME of its election to have all, or any portion of, such advance treated as a loan to the Defaulting Series ME 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 ME Percentage Interests.

(i) To the extent that one or more Non-Defaulting Series ME Partners do not elect to have an advance made pursuant to this Section 5.8(e) treated as a loan to the Defaulting Series ME Partner, or affirmatively elects to have such advance treated as a Capital Contribution, the Managing General Partner of the Series ME will automatically adjust the Series ME Percentage Interest of (A) each such Non-Defaulting Series ME Partner to equal the percentage obtained by dividing (x) the Series ME Capital Account of each such Non-Defaulting Series ME Partner (including any Capital Contribution made by such Non-Defaulting Series ME Partner

under this Section 5.8(e) multiplied by three) by (y) the sum of the Series ME Capital Accounts of all Series ME Partners (including all Capital Contributions made under this Section 5.8(e) multiplied by three) and (B) such Defaulting Series ME Partner to equal the amount of (x) such Defaulting Series ME Partner’s Series ME Percentage Interest immediately prior to the occurrence of such default less (y) the aggregate increases to the Series ME Percentage Interests of Non-Defaulting Series ME Partners pursuant to clause (A). Notwithstanding the foregoing, the Defaulting Series ME Partner will have the right to re-acquire the interest in question from any advancing Non-Defaulting Series ME Partner within 30 days following the date on which such Series ME Percentage Interest adjustment is made by paying the entire amount advanced by such Non-Defaulting Series ME 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, (B) 12% per annum or (C) in the case of an advance from EECI or its Affiliates to Enbridge Partners or its Subsidiaries, the rate that would be charged Enbridge Partners by unrelated lenders on a comparable loan, whereupon the Series ME Percentage Interests of each Series ME Partner shall be adjusted to equal the Percentage Interest such Series ME Partner would have had in the absence of a default by such Defaulting Series ME Partner.

(ii) To the extent one or more Non-Defaulting Series ME Partners (each, a “Lending Series ME Partner”) elects to have an advance made pursuant to this Section 5.8(e) constitute a loan to the Defaulting Series ME Partner, such advance will have the following results (except to the extent otherwise agreed by the Lending Series ME Partner and the Defaulting Series ME Partner, each in their sole discretion):

(A) the sum advanced will constitute a loan from the Lending Series ME Partner to the Defaulting Series ME Partner and an Additional Series ME Capital Contribution of that sum to the Series ME by the Defaulting Series ME 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 ME 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 ME Partner Obligation is made by the Lending Series ME Partner to the Defaulting Series ME Partner; provided, however, that the Defaulting Series ME Partner may prepay the Defaulting Series ME Partner Obligation in whole or in part at any time prior to the date due;

(D) the Lending Series ME 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 ME Partner may deem appropriate to obtain payment from the Defaulting Series ME Partner of the Defaulting Series ME Partner Obligation; and

(E) initially, a loan by a Lending Series ME Partner to a Defaulting Series ME Partner as contemplated by this Section 5.8(e)(ii) will not be considered a Capital Contribution by such Lending Series ME Partner and will not increase the Capital Account balance of such Lending Series ME 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 ME Partner, at any time thereafter by giving written notice to the Managing General Partner of the Series ME and the Defaulting Series ME Partner, may elect to have an amount equal to the unpaid principal and interest balance of such loan transferred from such Defaulting Series ME Partner’s Capital Account to such Lending Series ME Partner’s Capital Account and increase such Lending Series ME Partner’s Capital Account with a corresponding decrease in such Defaulting Series ME Partner’s Capital Account. Upon such transfer, the loan will be treated as a Capital Contribution and the Series ME Percentage Interest for (A) such Lending Series ME Partner will be automatically adjusted to equal the percentage obtained by dividing (x) the Capital Account of such Lending Series ME Partner (including any Capital Contribution made by such Lending Series ME Partner under this Section 5.8(e)(ii)(E) on behalf of the Defaulting Series ME Partner multiplied by three) by (y) the sum of the Series ME Capital Accounts of all Series ME Partners (including all Capital Contributions made under this Section 5.8(e)(ii)(E) on behalf of the Defaulting Series ME Partner multiplied by three) and (B) such Defaulting Series ME Partner will be automatically adjusted to equal the amount of (x) such Defaulting Series ME Partner’s Series ME Percentage Interest immediately prior to such election by the Lending Series ME Partner less (y) the increase to the Series ME Percentage Interest of Lending Series ME Partner pursuant to clause (A).

(f) Notwithstanding the rights of Non-Defaulting Series ME Partners described in Section 5.8(e), the Managing General Partner of the Series ME, by a vote of a Supermajority Interest of Series ME Partnership Interests (without taking into account the Series ME Partnership Interests of the Defaulting Series ME Partner), will have the right to exercise any rights and remedies available at law or in equity.

Section 5.9 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.

(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’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).

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

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

(iv) 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.

(v) Notwithstanding Sections 6.1(a)(i), 6.1(a)(ii), 6.1(a)(iii) and 6.1(a)(iv) 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, Series EA Partners or Series ME Partners pursuant to Section 6.2(c), Section 6.3(c) or Section 6.4(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, Series EA Partners or Series ME Partners, as applicable, pursuant to Section 6.2(c), Section 6.3(c) or Section 6.4(c) for such taxable year and all prior taxable years;

(B) in the event that the Series AC Partners become obligated to make payments to the Series LH Partners pursuant to Section 6.5(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 6.5(c) for such taxable year and all prior taxable years;

(C) in the event that the Series EA Partners become obligated to make payments to the Series LH Partners pursuant to Section 6.5(d), items of Partnership gross income and gain shall be allocated to the Series EA Partners in accordance with their respective Series EA Percentage Interests until the aggregate amounts of items allocated to the Series EA 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 EA Partners to the Series LH Partners pursuant to Section 6.5(d) for such taxable year and all prior taxable years; and

(D) in the event that the Series ME Partners become obligated to make payments to the Series LH Partners pursuant to Section 6.5(e), items of Partnership gross income and gain shall be allocated to the Series ME Partners in accordance with their respective Series ME Percentage Interests until the aggregate amounts of items allocated to the Series ME 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 ME Partners to the Series LH Partners pursuant to Section 6.5(e) 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, 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 (if such amount is greater

Such payment obligation shall be allocated Pro Rata among the Series LH Partners.

Notwithstanding any provision to the contrary contained in this Agreement, neither the Partnership nor the Series EA shall make any distribution to any Series EA Partner on account of its Series EA Partnership Interest if such distribution would violate the Delaware Act or any other applicable law.

(b) Notwithstanding Section 6.3(a), in the event of the dissolution and liquidation of the Partnership or the termination of the Series EA, 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.

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 7.13, 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 7.13 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 7.13(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 7.13.

(c) The indemnification provided by this Section 7.13 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 Partnership Interests, in the case of the Series AC and the Series LH, or a Supermajority Interest of the Partnership Interests, in the case of the Series EA and the Series ME, 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 7.13 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.

(i) The provisions of this Section 7.13 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.

Section 7.14 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 7.14 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 Sections 6.2, 6.3, 6.4 or 6.5 with respect to a shortfall related to the Liability that gave rise to the Series Indemnified Damages.

(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.

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 7.15 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 7.15 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.

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 7.18 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.

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.

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.

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.

(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 EA and the Series ME 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 EA Sub in the Series EA shall automatically convert into a General Partner Interest in the Series EA and the Limited Partner Interest of EECI ME Sub in the Series ME shall automatically convert into a General Partner Interest in the Series ME;

(ii) EECI EA Sub shall automatically become the Managing General Partner of the Series EA and EECI ME Sub shall automatically become the Managing General Partner of the Series ME, in each case, with all rights, powers and obligations of the Managing General Partner of such Series as set forth in this Agreement; and

(iii) all rights, powers and obligations of the existing Managing General Partner of the Series EA and Series ME (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 EA or Series ME) or (B) the Percentage Interest of the Series EA Partners or the Series ME Partners.

(c) In connection with the exercise of the Control 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 EA Sub, EECI ME Sub or the Managing General Partner of the Series EA or Series ME, as applicable, 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 Alberta Clipper Surcharge Expiration.

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

(b) If the Alberta Clipper 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 Alberta Clipper Revised Tariff Structure.

(c) If the Alberta Clipper 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 Lakehead GP and EECI, 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 Alberta Clipper 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 Alberta Clipper Surcharge Term. If EECI 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 and Lakehead GP are unable to agree on such allocation arrangement at least 180 days prior to the expiration or earlier termination of the Alberta Clipper Surcharge Term, then the matter will be submitted to arbitration pursuant to Section 10.2(d).

(d) If the Alberta Clipper 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 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 Alberta Clipper Surcharge Term. Each of EECI and Lakehead GP shall appoint an arbitrator at least 150 days prior to the expiration of the Alberta Clipper 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 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 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 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 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 Alberta Clipper Surcharge Term. EECI, 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.

Section 10.3 Eastern Access Surcharge Expiration.

(b) If the Eastern Access 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 EA Assets and (ii) the expenses that the Partnership is entitled to allocate in respect of the Series EA Assets, then the Series EA Revenue Entitlement and Series EA Expenses shall be calculated in accordance with the Eastern Access Revised Tariff Structure.

(c) If the Eastern Access 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 EA Assets and (ii) the expenses that the Partnership is entitled to allocate in respect of the Series EA Assets, then EECI EA 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 Series EA Tariff Term Sheet so affected. Such allocation arrangement will be based on the relative invested capital of each Series as of the expiration or earlier termination of the applicable Series EA Tariff Term Sheet. If EECI EA Sub and Lakehead GP are able to agree on such allocation arrangement, then the Series EA Revenue Entitlement and Series EA Expenses will be calculated in accordance with such arrangement. If EECI EA 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 applicable Series EA Tariff Term Sheet, then the matter will be submitted to arbitration pursuant to Section 10.3(d).

(d) If the Eastern Access 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 EA Assets and (ii) the expenses that the Partnership is entitled to allocate in respect of the Series EA Assets, and EECI EA Sub and Lakehead GP are unable to agree on an allocation arrangement pursuant to Section 10.3(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).

Each of EECI EA 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 EA 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 EA 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 EA Sub or the allocation arrangement of Lakehead GP, and shall have no power or authority whatsoever to reach any other result.

Except as provided in the Federal Arbitration Act, the decision of the arbitrators will be binding on and non-appealable by the parties.

(e) Notwithstanding the provisions of this Section 10.3, following the end of the Eastern Access Surcharge Term, EECI EA Sub and Lakehead GP may, by mutual agreement, elect to remove the Eastern Access Project from integrated common carrier service within the Lakehead System and transfer it to stand alone service either on a common carrier basis or on a contract basis, as permitted by applicable law. Upon the execution of such agreement, the Series EA Revenue Entitlement shall be determined by reference to the applicable toll principles established by applicable regulation or by contract for standalone service.

Section 10.4 Mainline Expansion Surcharge Expiration.

(a) Upon the expiration or earlier termination of the term of one or more of the Series ME Tariff Term Sheets, the Series ME Tariff Term Sheet so affected shall be replaced with a revised tariff structure in accordance with the provisions of the Series ME Tariff Term Sheets (the “Mainline Expansion Revised Tariff Structure”).

(b) If the Mainline Expansion 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 ME Assets and (ii) the expenses that the Partnership is entitled to allocate in respect of the Series ME Assets, then the Series ME Revenue Entitlement and Series ME Expenses shall be calculated in accordance with the Mainline Expansion Revised Tariff Structure.

(c) If the Mainline Expansion 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 ME Assets and (ii) the expenses that the Partnership is entitled to allocate in respect of the Series ME Assets, then EECI ME 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 Series ME Tariff Term Sheet so affected. Such allocation arrangement will be based on the relative invested capital of each Series as of the expiration or earlier termination of the applicable Series ME Tariff Term Sheet. If EECI ME Sub and Lakehead GP are able to agree on such allocation arrangement, then the Series ME Revenue Entitlement and Series ME Expenses will be calculated in accordance with such arrangement.

ARTICLE XI

DISSOLUTION AND LIQUIDATION

Section 11.1 Dissolution of the Partnership.

(a) The Partnership shall not be dissolved by the admission of additional Partners. The Partnership shall dissolve, and its affairs shall be wound up, upon:

(i) subject to Section 7.4(q) and Section 7.5(q), an election to dissolve the Partnership by the Managing General Partner of the Partnership generally and the Managing General Partner of each Series that is approved by a Majority in Interest of each of the Series AC and Series LH and a Supermajority Interest of the Series EA and Series ME;

(ii) the entry of a decree of judicial dissolution of the Partnership pursuant to the provisions of the Delaware Act;

(iii) the termination of the last remaining Series;

(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 each of the Series AC and Series LH and a Supermajority Interest of the Series EA and Series ME, 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 7.4(q) and Section 7.5(q), the approval of each General Partner of such Series and a Majority in Interest of the Partnership Interests of such Series, in the case of the Series AC and Series LH, or a Supermajority Interest of the Partnership Interests of such Series, in the case of Series EA and Series ME; 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 each of the Series AC and Series LH and a Supermajority Interest of the Series EA and Series ME, 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), 6.3(c), 6.4(c), 6.5(c), 6.5(d) or 6.5(e).

(b) Except as provided in Section 6.2(c), 6.3(c), 6.4(c), 6.5(c), 6.5(d), 6.5(e) 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.

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 the Partnership Interests of such Series, in the case of the Series AC and Series LH, or a Supermajority Interest of the Partnership Interests of such Series, in the case of Series EA and Series ME, or if with respect to the Partnership as a whole, the affirmative vote or written consent of a Majority in Interest of the Partnership Interests of the Series AC and Series LH and a Supermajority Interest of the Partnership Interests of the Series EA and Series ME.

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 the

Partnership Interests of such Series, in the case of the Series AC and Series LH, or a Supermajority Interest of the Partnership Interests of such Series, in the case of Series EA and Series ME, 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 the Partnership Interests of such Series, in the case of the Series AC and Series LH, or a Supermajority Interest of the Partnership Interests of such Series, in the case of Series EA and Series ME, 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.

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 7.4 and Section 7.5, 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, a Majority in Interest of the Partnership Interests of each of Series AC and Series LH and a Supermajority Interest of the Series EA Partnership Interests and Series ME Partnership Interests.
