Managing General Partner of the Partnership generally shall determine the portion of the Liabilities associated with or arising from the use, ownership or operation of the Shared Assets to be designated as Series AC Liabilities, Series EA

 TRANSFER OF PARTNERSHIP INTERESTS; 
 RIGHT OF FIRST REFUSAL; TAG-ALONG RIGHTS

 30 








 
Partnership generally or any Series. 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

(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. 

  
 31 








 (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.

Transfers of Partnership Interests. 
 (a) Series AC and Series EA Partnership Interests. No
Transfer of a Series AC or Series EA 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 4.4, 4.5 or 4.6. 
 (b)
Series LH Partnership Interests. No Transfer of a Series LH 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 Section 4.4. 
 Section 4.4 Series
AC and Series LH 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 (i) in the case of EECI and EECI AC Sub and their respective Permitted Transferees, such Partner’s Partnership Interests in Series AC or (ii) in
the case of Enbridge Partners, Lakehead GP, Wisconsin GP and their respective Permitted Transferees, such Partner’s Partnership Interests in the Partnership generally, Series AC or Series LH, and such Partner (the “Offering
Partner”) desires to accept and is otherwise permitted to effect such proposed Transfer pursuant to this Article IV, such Offering Partner shall deliver written notice of such Third Party Offer (the “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 ROFR Notice is received by the Managing General Partner of
the Partnership generally shall constitute the “ROFR Notice Date.” Within five Business Days following the ROFR Notice Date, the Managing General Partner of the Partnership generally shall send a copy of the ROFR Notice along with a
letter indicating the ROFR Notice Date to EECI and Enbridge Partners (each, a “ROFR Holder” and collectively, the “ROFR Holders”). The 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 “Offered Interests”), the proposed purchase price for the Offered Interests (the “ROFR Offer
Price”), all details of the payment terms and all other material terms and conditions, including the nature of the 

  
 32 








 
representations and warranties to be made and the indemnities to be given, in connection with the proposed Transfer. The ROFR Offer Price shall be expressed in U.S. dollars, whether or not the
form of consideration in the Third Party Offer is wholly or partially cash or cash equivalents. 
 (b) Each ROFR
Holder shall have the right, but not the obligation, to purchase up to that amount of the Offered Interests equal to the product of (i) the amount of the Offered Interests and (ii) a fraction (the “ROFR Proportionate
Share”), the numerator of which shall be the Series AC Percentage Interest of such ROFR Holder and the denominator of which shall be the sum of the Series AC Percentage Interests held by the ROFR Holders. Within 25 days after the ROFR
Notice Date, each ROFR Holder may deliver a written notice to the Offering Partner, the Managing General Partner of the Partnership generally and the other ROFR Holder of its election to purchase such Offered Interests. Any ROFR Holder whose written
notice has not been received by the Managing General Partner of the Partnership generally within such 25-day period shall be deemed to have elected not to exercise its right of first refusal in connection with such Transfer. To the extent a ROFR
Holder does not elect to purchase its full ROFR Proportionate Share of such Offered Interests, the other ROFR Holder, if it has elected to purchase its full ROFR Proportionate Share, shall be entitled, by delivering written notice to the Offering
Partner and the Managing General Partner of the Partnership generally within five Business Days following the end of such 25-day period (such fifth Business Day, the “ROFR Expiration Date”), to purchase up to all of the remaining
Offered Interests. The delivery of a notice of election under this Section 4.4(b) shall constitute an irrevocable commitment to purchase such Offered Interests. If the ROFR Holders shall have elected to purchase all but not less than all of the
Offered Interests, the Managing General Partner of the Partnership generally shall thereafter set a reasonable place and time for the closing of the purchase and sale of the Offered Interests, which shall be not less than 10 days nor more than 60
days after the ROFR Expiration Date (subject to extension to the extent necessary to pursue any required regulatory or Partner approvals, including to allow for the expiration or termination of all waiting periods under the HSR Act) unless otherwise
agreed by all of the parties to such transaction. 
 (c) The purchase price and terms and conditions for the
purchase of the Offered Interests pursuant to this Section 4.4 shall be the purchase price and terms and conditions set forth in the applicable Third Party Offer (or the cash equivalent thereof); provided that the purchase price shall be
the ROFR Offer Price and shall be payable in immediately available U.S. dollars; and provided further that the Offering Partner shall at a minimum make customary representations and warranties concerning (i) such Offering Partner’s
valid title to and ownership of the Offered Interests, free and clear of all liens, claims and encumbrances (excluding those arising hereunder and under applicable securities laws), (ii) such Offering Partner’s authority, power and right
to enter into and consummate the sale of the Offered Interests, (iii) the absence of any violation, default or acceleration of any agreement or obligation to which such Offering Partner is subject or by which its assets are bound as a result of
the sale of the Offered Interests and (iv) the absence of, or compliance with, any governmental or third party consents, approvals, filings or notifications required to be obtained or made by such Offering Partner in connection with the sale of
the Offered Interests. The Offering Partner and participating ROFR Holders shall use commercially reasonable efforts to close the purchase of the Offered Interests as soon as reasonably practicable following the ROFR Expiration Date and shall each
execute and deliver such instruments and documents and take such actions, including obtaining all applicable approvals and consents and making all applicable notifications and filings, as the other parties may reasonably request in order more
effectively to implement the purchase and sale of the Offered Interests hereunder. 

  
 33 








 (d) Notwithstanding the foregoing, if (i) the ROFR Holders
(A) shall have elected to purchase less than all of the Offered Interests or (B) shall not have elected to purchase any of the Offered Interests on or prior to the ROFR Expiration Date, and the Offering Partner has fully complied with the
provisions of this Section 4.4, then the Offering Partner may sell all, but not less than all, of the Offered Interests within 90 days after the ROFR Expiration Date (subject to extension for a reasonable amount of time to the extent necessary
to obtain any required regulatory or Partner approvals, including to allow for the expiration of all waiting periods under the HSR Act) or (ii) if the ROFR Holders fail to consummate the closing of the purchase and sale of the Offered Interests
within the time period provided in the last sentence of Section 4.4(b) (such period, the “ROFR Closing Period”) and the Offering Partner has fully complied with the provisions of this Section 4.4, then the Offering Partner
may sell all, but not less than all, of the Offered Interests within 90 days after the expiration of the ROFR Closing Period to the Third Party, in each case subject to the provisions of Section 4.2. Any such sale shall not be at less than the
purchase price or upon terms and conditions more favorable in any material respect, individually or in the aggregate, to the purchaser than those specified in the Third Party Offer. If the Offered Interests are not so transferred within the
applicable time periods specified in this Section 4.4(d), the Offering Partner may not sell any of the Offered Interests without again complying in full with the provisions of this Article IV. 

(e) Each of EECI and Enbridge Partners shall be entitled to assign any rights it has to purchase Offered Interests
pursuant to this Section 4.4 to any of its Permitted Transferees. 
 (f) This Section 4.4 shall not
apply to any Transfer or proposed Transfer of Partnership Interests to a Permitted Transferee. 
 Section 4.5 Series EA 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 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 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 

  
 34 








 
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


  
 35 








 
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 Tag-Along Rights.

 (a) If a Series AC Partner or Series EA Partner (the “Transferor”) proposes to Transfer
all or a part of its Partnership Interests in Series AC or Series EA 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 a ROFR Notice
or EA ROFR Notice and may be conditioned upon the ROFR Holders not exercising the right of first refusal contained in Section 4.4 or Section 4.5. 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 

  
 36 








 
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 AC or Series EA, 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 

  
 37 








 
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 4.7 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 4.7, 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 4.7 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 4.7 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 

  
 38 








 
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 4.7, 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 4.7(b) (such period, the “ROFR Asset Closing Period”) and the Series has fully complied with the provisions of this Section 4.7, 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 and Section 7.4,
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 4.7(d), the Series may not sell the ROFR Offered Asset without again complying in full with the provisions of this Section 4.7.

 (e) EECI shall be entitled to assign any rights it has to purchase a ROFR Offered Asset pursuant to this
Section 4.7 to any of its Permitted Transferees. 
 (f) This Section 4.7 shall not apply to any
transfer or proposed transfer of assets to a Permitted Transferee. 
 Section 4.8 Enbridge Partners Call Option. 

(a) From time to time prior to the twelve-month anniversary of the Eastern Access Final In-Service Date (the “Call
Option Deadline”), Enbridge Partners shall have the right to purchase, and EECI shall have the obligation to sell (the “Enbridge Partners 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 4.8. In considering whether to exercise the Enbridge Partners Call Option, the Board of
Directors of Enbridge Energy Management, L.L.C. (the “EEM Board”) shall establish a 

  
 39 








 
committee of independent directors (an “Option Committee”) to make a recommendation to the EEM Board, on behalf of Enbridge Partners, whether to exercise the Enbridge Partners
Call Option and the portion of Series EA Limited Partner Interests held by EECI that Enbridge Partners will purchase if the Enbridge Partners 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 Enbridge Partners Call Option following receipt of the Option Committee’s recommendation, Enbridge Partners shall deliver to the Partnership and to EECI, prior to the Call Option Deadline, written notice (each, a “Call Option
Notice”) of such determination. Each 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) (a “Call Option Interest”) and the corresponding amount of consideration to be paid, calculated in accordance with Section 4.8(c), (ii) the proposed date of purchase and
(iii) other proposed material terms and conditions of such sale. Upon receipt of each Call Option Notice, EECI agrees to promptly take all necessary and desirable actions in connection with the exercise of the Enbridge Partners 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 Call Option Interest hereunder. Each date on which the
purchase and sale of a Call Option Interest is consummated is referred to as a “Call Option Interest Closing Date.” Such agreements and instruments shall contain customary representations and warranties concerning
(i) EECI’s valid title to and ownership of the 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 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 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 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 4.8. 
 (c) The purchase price to be paid by Enbridge Partners to EECI for the purchase of a Call
Option Interest shall equal the capital contributed by EECI in respect of such 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 Call Option Interest Closing Date, and (ii) the quotient, expressed as a percentage, obtained by dividing the Call Option Interest by the total outstanding Series
EA Partnership Interests. 

  
 40 








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

Section 4.9 Enbridge Partners Put Option. 
 (a) From time to time prior to December 31, 2012 (the “Put Option Deadline”), Enbridge Partners shall have the right to sell, and EECI shall have the obligation to purchase (the
“Enbridge Partners Put Option”), a portion of the Series EA Limited Partner Interests held by Enbridge Partners 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 Enbridge Partners Put 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 Enbridge Partners Put Option and the portion of Series EA Limited Partner Interests held by Enbridge Partners that EECI will purchase if the Enbridge Partners Put 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 Enbridge Partners Put Option following receipt of the Option Committee’s recommendation, Enbridge Partners shall deliver to the Partnership and to EECI, prior to the Put Option Deadline, written
notice (each, a “Put Option Notice”) of such determination. Each Put Option Notice shall state (i) the portion of the Series EA Limited Partner Interests held by Enbridge Partners proposed to be sold (not to exceed, in the
aggregate, fifteen percent (15%) of the total outstanding Series EA Partnership Interests) (a “Put Option Interest”), (ii) the proposed date of purchase and (iii) other proposed material terms and conditions of such
sale. Upon receipt of the Put Option Notice, EECI agrees to promptly take all necessary and desirable actions in connection with the exercise of the Enbridge Partners Put 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 Put Option Interest hereunder. Each date on which the purchase and sale of a Put Option Interest is consummated is referred to as
a “Put Option Interest Closing Date.” Such agreements and instruments shall contain customary representations and warranties concerning (i) Enbridge Partners’ valid title to and ownership of the Put Option Interest, free
and clear of all liens, claims and encumbrances (excluding those arising under this Agreement and applicable securities laws), (ii) Enbridge Partners’ authority, power and right to enter into and consummate the sale of the Put Option
Interest, (iii) the absence of any violation, 

  
 41 








 
default or acceleration of any agreement to which Enbridge Partners is subject or by which its Partnership Interests are bound as a result of the agreement to sell and the sale of the Put 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 Enbridge Partners in connection with the sale of the Put Option Interest.
EECI shall execute and deliver such instruments and documents and take such actions 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 EECI to Enbridge Partners for the purchase of a Put Option Interest shall equal the capital contributed by Enbridge Partners in respect of such Put 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 Put Option Interest Closing Date, and (ii) the quotient, expressed as
a percentage, obtained by dividing the Put Option Interest by the total outstanding Series EA Partnership Interests. 
 (d) If and to the extent that any distributions accruing on a Put Option Interest that are attributable to the operations of the Series EA prior to the applicable Put Option Interest Closing Date are
declared or paid on or after such Put Option Interest Closing Date (a “Put Option Distribution”), Enbridge Partners shall be entitled to receive, and the Partnership shall pay to Enbridge Partners, subject to the Delaware Act,
(i) with respect to a Quarter occurring prior to the Quarter in which the Put Option Interest Closing Date occurs for which distributions on the Series EA Partnership Interests have not been declared and/or paid as of the Put Option Closing
Date, an amount equal to the Put Option Distribution and (ii) with respect to a Quarter in which the Put Option Closing Date occurs, an amount equal to the product of (x) the Put Option Distribution and (y) the quotient obtained by
dividing the number of days the Put Option Interest was held by Enbridge Partners during such Quarter by the total number of days in such Quarter. 
 Section 4.10 Specific Performance. 
 Each Partner
acknowledges that it shall be inadequate or impossible, or both, to measure in money the damage to the Partnership, any Series or the Partners, if any of them or any transferee or any legal representative of any party hereto fails to comply with any
of the restrictions or obligations imposed by this Article IV, that every such restriction and obligation is material, and that in the event of any such failure, the Partnership, the Series and the Partners shall not have an adequate remedy at
law or in damages. Therefore, each Partner consents to the issuance of an injunction or the enforcement of other equitable remedies against such Partner at the suit of an aggrieved party without the posting of any bond or other security, to compel
specific performance of all of the terms of this Article IV and to prevent any transfer of Partnership Interests or ROFR Offered Assets in contravention of any terms of this Article IV, and waives any defenses thereto, including the
defenses of: (i) failure of consideration; (ii) breach of any other provision of this Agreement and (iii) availability of relief in damages.

 CAPITAL CONTRIBUTIONS; PARTNERSHIP INTERESTS; 
 FUTURE CAPITAL REQUIREMENTS

 Section 5.1 Series LH Partnership Interests and Capital Contributions. 

The Percentage Interests of each Series LH General Partner and Series LH Limited Partner as of the Series EA Closing Date
are as set forth on Exhibit A. Any Series LH Limited Partner, with the consent of the Managing General Partner of the Series LH, may, but shall not be obligated to, make additional Capital Contributions to the Series LH. Upon
any such additional Capital Contribution, each Series LH General Partner and any other Series LH Limited Partner shall be obligated to make an additional Capital Contribution to the Series LH in an amount necessary to maintain its
Series LH Percentage Interest. 
 Section 5.2 Initial Series AC Capital Contributions and Initial AC Debt Financing.

 (a) On the Series AC Closing Date, each of the Series AC Partners made its respective Capital
Contribution (each, an “Initial Series AC Capital Contribution”) to the Series AC in immediately available U.S. dollars in the amounts set forth opposite its name on Exhibit A in return for the Series AC
Percentage Interest and type of Series AC Partnership Interest set forth opposite its name on Exhibit A, and, upon its execution of the Prior Agreement and the making of its Initial Series AC Capital Contribution, each such
Series AC Partner was admitted as a Partner of the Series AC in the capacity set forth opposite its name on Exhibit A. 
 (b) On the Series AC Closing Date, the Series AC (i) borrowed under Facility B1 an amount equal to 66.67% of 45% of the Preliminary Alberta Clipper Construction Costs and (ii) borrowed
under Facility C1 an amount equal to 33.33% of 45% of the Preliminary Alberta Clipper Construction Costs. 

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

Section 5.3 Additional Series AC Capital Contributions. 

(a) Each Series AC Partner hereby agrees to make additional Capital Contributions to the Series AC (the
“Additional Series AC Capital Contributions”) in proportion to such Series AC Partner’s Series AC Percentage Interest at such times and in such amounts as the Managing General Partner of the Series AC shall
specify in a notice delivered to the Series AC Partners pursuant to Section 5.3(b) (“Series AC Capital Contribution Notice”); provided that in no event shall any Series AC Partner be required to make, in
the aggregate, Capital Contributions in excess of such Series AC Partner’s respective Maximum Commitment with respect to Series AC set forth on Exhibit A. All Additional Series AC Capital Contributions shall be contributed
to the Series AC in immediately available U.S. dollars on the date specified in the applicable Series AC Capital Contribution Notice. No Series AC Partner shall be required to make any Additional Series AC Capital Contribution,
or to otherwise contribute any amount, to the Series AC unless such Additional Series AC Capital Contribution is reflected on the Series AC Annual Budget for such fiscal year or is otherwise approved by the Managing General Partner of
the Series AC and a Majority in Interest of Series AC Partnership Interests. 

  
 43 








 (b) From time to time following the Alberta Clipper In-Service Date, the
Managing General Partner of the Series AC may deliver to the Series AC Partners a Series AC Capital Contribution Notice related to amounts that the Managing General Partner of the Series AC determines are necessary to fund the
Series AC’s operations and establish reasonable reserves in respect of the Series AC’s expenses. Such notice shall set forth (i) the manner in which, and the expected date on which, such Additional Series AC Capital
Contribution is to be applied, (ii) the amount of the required Additional Series AC Capital Contribution to be made by such Series AC Partner, which shall be an amount equal to such Series AC Partner’s Pro Rata portion of
the total amount of such Additional Series AC Capital Contribution, (iii) the date on which such Additional Series AC Capital Contribution is due, which shall not be less than 10 Business Days from the date such notice is delivered
and (iv) the Person or the account to which such Additional Series AC Capital Contribution is to be made. 
 (c) Each Series AC Partner agrees that payment of its required Additional Series AC Capital Contributions under this Agreement is an obligation of such Series AC Partner, that any default
by any Series AC Partner would cause injury to the Series AC and to the other Series AC Partners and that the amount of damages caused by any such default would be difficult to calculate. 

(d) If a Series AC Partner fails to fund all or any portion of its required Additional Series AC Capital
Contribution set forth in a Series AC Capital Contribution Notice and fails to cure such default within five Business Days after the due date set forth in such Series AC Capital Contribution Notice (the “Default Series AC Capital
Contribution”), the Series AC Partner failing to make such contribution (the “Defaulting Series AC Partner”) will be in default. Upon the occurrence of any such default, the Managing General Partner of
Series AC shall promptly notify the Defaulting Series AC Partner and the other Series AC Partners not in default (each a “Non-Defaulting Series AC Partner”) of the occurrence of such default. As long as a Default
Series AC Capital Contribution remains unpaid or arrangements for the payment thereof have not been agreed to by the Series AC Partners, any Non-Defaulting Series AC Partner may advance to the Series AC the entire amount of the Defaulting
Series AC Partner’s Capital Contribution that has not been contributed, with each Non-Defaulting Series AC Partner electing to participate in such advance making its share of such advance in proportion to its Series AC Percentage Interest
(without taking into account the Series AC Percentage Interest of the Defaulting Series AC Partner). Each Non-Defaulting Series AC Partner who makes such an advance on behalf of a Defaulting Series AC Partner will have the right to elect the extent
to which such advance will (x) constitute a loan to the Defaulting Series AC Partner and/or (y) be treated as a Capital Contribution by such Non-Defaulting Series AC Partner and result in an immediate adjustment of the Series AC Percentage
Interests of the Defaulting Series AC Partner and the Non-Defaulting Series AC Partner making such election in accordance with Section 5.3(d)(i); provided, however, that if the advancing Non-Defaulting Series AC Partner does not notify
the Managing General Partner of the Series AC of its election to have all, or any portion of, such advance treated as a loan to the Defaulting Series AC Partner, in writing, at the time the advance is made, then such advance shall be deemed a
Capital Contribution and will automatically result in an immediate adjustment of the Series AC Percentage Interests. 

  
 44 








 (i) To the extent that one or more Non-Defaulting Series AC Partners do not
elect to have an advance made pursuant to this Section 5.3(d) treated as a loan to the Defaulting Series AC Partner, or affirmatively elects to have such advance treated as a Capital Contribution, the Managing General Partner of the Series AC
will automatically adjust the Series AC Percentage Interest of (A) each such Non-Defaulting Series AC Partner to equal the percentage obtained by dividing (x) the Series AC Capital Account of each such Non-Defaulting Series AC Partner
(including any Capital Contribution made by such Non-Defaulting Series AC Partner under this Section 5.3(d) multiplied by three) by (y) the sum of the Series AC Capital Accounts of all Series AC Partners (including all Capital
Contributions made under this Section 5.3(d) multiplied by three) and (B) such Defaulting Series AC Partner to equal the amount of (x) such Defaulting Series AC Partner’s Series AC Percentage Interest immediately prior to the
occurrence of such default less (y) the aggregate increases to the Series AC Percentage Interests of Non-Defaulting Series AC Partners pursuant to clause (A). Notwithstanding the foregoing, the Defaulting Series AC Partner will have the right
to re-acquire the interest in question from any advancing Non-Defaulting Series AC Partner within 30 days following the date on which such Series AC Percentage Interest adjustment is made by paying the entire amount advanced by such Non-Defaulting
Series AC Partner in return for such adjustment, plus interest thereon at a rate equal to the lesser of (A) the maximum, lawful interest rate, compounded monthly, that is then-currently permitted under applicable law, (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 AC Percentage
Interests of each Series AC Partner shall be adjusted to equal the Percentage Interest such Series AC Partner would have had in the absence of a default by such Defaulting Series AC Partner. 

(ii) To the extent one or more Non-Defaulting Series AC Partners (each, a “Lending Series AC Partner”)
elects to have an advance made pursuant to this Section 5.3(d) constitute a loan to the Defaulting Series AC Partner, such advance will have the following results (except to the extent otherwise agreed by the Lending Series AC Partner and the
Defaulting Series AC Partner, each in their sole discretion): 
 (A) the sum advanced will constitute a loan
from the Lending Series AC Partner to the Defaulting Series AC Partner and an Additional Series AC Capital Contribution of that sum to the Series AC by the Defaulting Series AC Partner pursuant to the applicable provisions of this Agreement;

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

  
 45 








 (D) the Lending Series AC Partner will have the right, in addition to the
other rights and remedies granted to it pursuant to this Agreement, to take any action available to it at law or in equity that the Lending Series AC Partner may deem appropriate to obtain payment from the Defaulting Series AC Partner of the
Defaulting Series AC Partner Obligation; and 
 (E) initially, a loan by a Lending Series AC Partner to a
Defaulting Series AC Partner as contemplated by this Section 5.3(d)(ii) will not be considered a Capital Contribution by such Lending Series AC Partner and will not increase the Capital Account balance of such Lending Series AC Partner.
Notwithstanding the foregoing, if the principal and interest of any such loan have not been repaid within one year from the date of the loan, a Lending Series AC Partner, at any time thereafter by giving written notice to the Managing General
Partner of the Series AC and the Defaulting Series AC Partner, may elect to have an amount equal to the unpaid principal and interest balance of such loan transferred from such Defaulting Series AC Partner’s Capital Account to such Lending
Series AC Partner’s Capital Account and increase such Lending Series AC Partner’s Capital Account with a corresponding decrease in such Defaulting Series AC Partner’s Capital Account. Upon such transfer, the loan will be treated as a
Capital Contribution and the Series AC Percentage Interest for (A) such Lending Series AC Partner will be automatically adjusted to equal the percentage obtained by dividing (x) the Capital Account of such Lending Series AC Partner
(including any Capital Contribution made by such Lending Series AC Partner under this Section 5.3(d)(ii)(E) on behalf of the Defaulting Series AC Partner multiplied by three) by (y) the sum of the Series AC Capital Accounts of all Series
AC Partners (including all Capital Contributions made under this Section 5.3(d)(ii)(E) on behalf of the Defaulting Series AC Partner multiplied by three) and (B) such Defaulting Series AC Partner will be automatically adjusted to equal the
amount of (x) such Defaulting Series AC Partner’s Series AC Percentage Interest immediately prior to such election by the Lending Series AC Partner less (y) the increase to the Series AC Percentage Interest of Lending Series AC
Partner pursuant to clause (A). 
 (e) Notwithstanding the rights of Non-Defaulting Series AC Partners described
in Section 5.3(d), the Managing General Partner of the Series AC, by a vote of a Majority in Interest of Series AC Partnership Interests (without taking into account the Series AC Partnership Interests of the Defaulting Series AC Partner), will
have the right to exercise any rights and remedies available at law or in equity. 
 Section 5.4 Future Alberta Clipper Expansions.

 (a) Any Series AC Partner may from time to time propose an expansion of the capacity of the Alberta
Clipper System (each, an “Alberta Clipper Expansion Project”) by providing a written proposal setting forth in reasonable detail the terms of such Alberta Clipper Expansion Project, including a budget and capital expenditure plan
(an “Alberta Clipper Expansion Proposal”), to each Series AC Partner. Promptly following its receipt of an Alberta Clipper Expansion Proposal, the Managing General Partner of the Series AC shall use its commercially
reasonable efforts to develop, and negotiate with shippers regarding, the tolling 

  
 46 








 
and other financial terms for such Alberta Clipper Expansion Project that include objectively determinable incremental revenues and costs (the “Alberta Clipper Expansion Project
Terms”) that are as favorable to the Alberta Clipper Expansion Project as can reasonably be achieved; provided, however, that the Managing General Partner of the Series AC shall not be obligated to seek any Alberta
Clipper Expansion Project Terms that could reasonably be expected to have a material adverse impact on any Series. The Managing General Partner of the Series AC shall not agree to any Alberta Clipper Expansion Project Terms that could
reasonably be expected to have a material adverse impact on any Series without the consent of a Majority in Interest of such Series (excluding for purposes of any such vote of the Series AC Partners or the Partners of an Alberta Clipper
Expansion Series that is not wholly owned by any Partner and its Affiliates (i) prior to the occurrence of a Fundamental Change, the Partnership Interests owned by the Managing General Partner of the Series AC and its Affiliates and
(ii) following the occurrence of a Fundamental Change, the Partnership Interests owned by EECI and its Affiliates). The Managing General Partner of the Series AC shall provide written notice of the Alberta Clipper Expansion Project Terms
to each Series AC Partner promptly following the determination of the Alberta Clipper Expansion Project Terms. 
 (b) Enbridge Partners shall have the right, but not the obligation, to provide all or any portion of the debt and equity financing required in connection with each Alberta Clipper Expansion Project (the
“Alberta Clipper Expansion Capital Requirement”) by providing written notice of its election to participate in the Alberta Clipper Expansion Project to the Series AC Partners as soon as reasonably practicable but in any event
within 30 days following the receipt of the Alberta Clipper Expansion Project Terms. If Enbridge Partners does not elect to fund 100% of the Alberta Clipper Expansion Capital Requirement, EECI shall have the right, but not the obligation, to fund
the portion of the Alberta Clipper Expansion Capital Requirement that Enbridge Partners has elected not to fund. If EECI elects to fund such portion, it shall provide written notice to Enbridge Partners promptly following receipt of Enbridge
Partners’ notice of election to fund a portion of the Alberta Clipper Expansion Capital Requirement. If EECI and/or Enbridge Partners do not elect to fund 100% of the Alberta Clipper Expansion Capital Requirement, then the Alberta Clipper
Expansion Project will not be undertaken by the Partnership or any Series. Enbridge Partners and EECI may fund their respective portions of any Alberta Clipper Expansion Capital Requirement pursuant to this Section 5.4 either directly or
through a Subsidiary or a controlled Affiliate. 
 (c) If the Alberta Clipper Expansion Capital Requirement is
to be provided Pro Rata by the Series AC Partners, all assets related to such Alberta Clipper Expansion Project shall be designated as Series AC Assets, and all Liabilities related to such Alberta Clipper Expansion Project shall be
designated as Series AC Liabilities. Capital Contributions associated with such Alberta Clipper Expansion Project shall be Additional Series AC Capital Contributions. 

(d) The assets of any Alberta Clipper Expansion Project that is undertaken but that are not designated as Series AC
Assets under Section 5.4(c) shall, at the election of the Managing General Partner, be designated as either (i) assets of a new series of partnership interests in the Partnership to be held by the Partners participating in such Alberta
Clipper Expansion Project in proportion to their respective capital contributions in respect of such Alberta Clipper Expansion Project (an “Alberta Clipper Expansion Series”) or (ii) Series LH Assets, provided that
Enbridge Partners elects to fund 100% of the Alberta Clipper Expansion 

  
 47 








 
Capital Requirement of such Alberta Clipper Expansion Project. Subject to Section 7.3, the Managing General Partner of the Partnership generally is hereby authorized to take all actions
necessary to create and establish the Alberta Clipper Expansion Series with such rights, powers and duties as the Managing General Partner of the Partnership generally and the Persons becoming Partners of such new Series shall determine, including
to amend this Agreement and its exhibits to set forth all relevant terms applicable to such Series. The Persons becoming Partners of such Alberta Clipper Expansion Series shall be admitted to the Partnership with respect to such Series as Partners
upon their execution of a counterpart to this Agreement in their capacity as Partners of such Alberta Clipper Expansion Series. 
 (e) Notwithstanding anything to the contrary in this Agreement, the parties hereto hereby acknowledge and agree that the Eastern Access Project and the Mainline Expansion Project shall not be considered
an Alberta Clipper Expansion Project for purposes of this Section 5.4. 
 Section 5.5 Initial Series EA
Capital Contributions. 
 (a) On the Series EA Closing Date, each of the Series EA Partners shall make
its respective Capital Contribution (each, an “Initial Series EA Capital Contribution”) to the Series EA in immediately available U.S. dollars in the amounts set forth opposite its name on Exhibit A in return
for the Series EA Percentage Interest and type of Series EA Partnership Interest set forth opposite its name on Exhibit A, and, upon its execution of this Agreement and the making of its Initial Series EA Capital
Contribution, each such Series EA Partner shall be admitted as a Partner of the Series EA in the capacity set forth opposite its name on Exhibit A. 

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

  
 48 








 (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 

  
 49 








 
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; 

  
 50 








 (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. 

  
 51 








 Section 5.7 Interest and Withdrawal of Capital Contributions. 

No interest shall be paid by the Partnership or any Series on Capital Contributions. No Partner shall be entitled to the
withdrawal or return of its Capital Contribution, except to the extent, if any, that distributions made pursuant to this Agreement or upon dissolution of the Partnership or the termination of any Series may be considered as such by law and then only
to the extent expressly provided for in this Agreement. Except to the extent expressly provided in this Agreement, no Partner shall have priority over any other Partner either as to the return of Capital Contributions or as to Profits, Losses or
distributions. Any such return shall be a compromise to which all Partners agree within the meaning of Section 17-502(b) of the Delaware Act. 
 Section 5.8 Capital Accounts. 
 (a) A separate Capital
Account shall be established and maintained for each Partner in accordance with the requirements of Treasury Regulation Section 1.704-1(b)(2)(iv). A Partner that owns a Partnership Interest in more than one Series shall have a single Capital
Account that reflects all such Partnership Interests; provided, however, that Series Capital Accounts shall be maintained for each Partner in accordance with the requirements of Treasury Regulation Section 1.704-1(b)(2)(iv). A
Partner’s Capital Account balance shall be the sum of the balances of each of such Partner’s Series Capital Accounts. 
 (b) Each Series Capital Account for each Partner shall be increased by (i) the amount of money contributed by that Partner to the Partnership with respect to a Series, (ii) the Book Value of

 ARTICLE VI  
 ALLOCATIONS AND DISTRIBUTIONS 
 Section 6.1 Allocations for Capital
Account Purposes. 
 (a) Allocations. For purposes of maintaining the Series Capital Accounts pursuant
to Section 5.8 and in determining the rights of the Partners among themselves with respect to each Series, after making all of the allocations under Sections 6.1(b) and 6.1(c), Profits and Losses and items thereof with respect to a Series shall
be allocated among the Partners of such Series in each taxable year (or portion thereof) as provided herein below. 
 (i) Series AC. Each item of income, gain, loss, deduction and credit attributable to Series AC Assets and Series AC Liabilities shall be allocated to the Series AC Partners in
accordance with their respective Series AC Percentage Interests. 
 (ii) Series 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 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. 
 (iv) Notwithstanding Sections 6.1(a)(i), 6.1(a)(ii) and 6.1(a)(iii), 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. 

  
 53 








 (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 or
Series EA Partners pursuant to Section 6.2(c) or Section 6.3(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 or Series EA Partners, as applicable, pursuant to Section 6.2(c) or Section 6.3(c) for such taxable year and all prior taxable years; and 

  
 54 








 (B) in the event that the Series AC Partners become obligated to make
payments to the Series LH Partners pursuant to Section 6.4(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 6.4(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 6.4(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 6.4(d) 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. 

  
 55 








 (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


  
 56 








 
than zero) with respect to such Quarter (the “Series AC Distribution”). Notwithstanding any provision to the contrary contained in this Agreement, neither the Partnership
nor the Series AC shall make any distribution to any Series AC Partner on account of its Series AC Partnership Interest if such distribution would violate the Delaware Act or any other applicable law. 

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

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

Section 6.3 Requirement and Characterization of Series EA Distributions; Distributions to Series EA Partners.

 (a) Within 45 days following the end of each Quarter commencing with the Quarter in which the Eastern Access
First In-Service Date occurs, the Partnership in respect of the Series EA shall distribute Pro Rata to the Series EA Partners as of the last day of such Quarter an amount in cash equal to the Series EA Distribution Amount (if such
amount is greater than zero) with respect to such Quarter (the “Series EA Distribution”). 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.

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

Section 6.4 Distributions to Series LH Partners. 

(a) On the date that the Series AC Distribution and Series EA Distribution is made pursuant to Section 6.2(a)
and Section 6.3(a), as applicable, the Managing General Partner of the Series LH may, in its sole discretion, cause the Partnership in respect of the Series LH to distribute Pro Rata to the Series LH Partners any cash that is not
otherwise required under this Agreement to be distributed to the Partners of any other Series or properly reserved by any other Series in accordance with this Agreement (the “Series LH Distribution”). Notwithstanding any
provision to the contrary contained in this Agreement, neither the Partnership nor Series LH shall make any distribution to any Series LH Partner on account of its Series LH Partnership Interest if such distribution would violate the
Delaware Act or other applicable law. 

  
 57 








 (b) Notwithstanding Section 6.4(a), in the event of the dissolution and
liquidation of the Partnership or the termination of the Series LH, all cash receipts received during or after the Quarter in which the Liquidation Date occurs shall be applied and distributed solely in accordance with, and subject to the terms
and conditions of, Section 11.3. 
 (c) If, for any Quarter (including the Quarter in which the liquidation
of the Series LH is completed), the Series AC Distribution Amount is less than zero, then the Series AC Partners shall promptly pay to the Series LH Partners Pro Rata in cash an amount equal to the aggregate amount by which the
Series AC Distribution Amount was less than zero. Such payment obligation shall be allocated Pro Rata among the Series AC Partners. 
 (d) If, for any Quarter (including the Quarter in which the liquidation of the Series LH is completed), the Series EA Distribution Amount is less than zero, then the Series EA Partners
shall promptly pay to the Series LH Partners Pro Rata in cash an amount equal to the aggregate amount by which the Series EA Distribution Amount was less than zero. Such payment obligation shall be allocated Pro Rata among the Series EA
Partners.

(a) To the fullest extent permitted by law but subject to the limitations expressly provided in this Agreement, each
Series shall indemnify and hold harmless all of such Series’ Indemnitees from and against any and all losses, claims, damages, liabilities, joint or several, expenses (including legal fees and expenses), judgments, fines, penalties, interest,
settlements or other amounts (“Damages”) arising from any and all claims, demands, actions, suits or proceedings, whether civil, criminal, administrative or investigative (“Claims”), in which any such Indemnitee may
be involved, or is threatened to be involved, as a party or otherwise, by reason of its management of the affairs of such Series or by reason of its status as an Indemnitee of such Series, that relates to or arises out of such Series, its property,
its business or its affairs; provided, that the Indemnitee shall not be indemnified and held harmless if there has been a final and non-appealable judgment entered by a court of competent jurisdiction determining that, in respect of the
matter for which the Indemnitee is seeking indemnification pursuant to this Section 7.10, 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 7.10 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 7.10(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 7.10. 

(c) The indemnification provided by this Section 7.10 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 Series LH, or a Supermajority Interest of the Partnership Interests, in the case of Series EA,
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. 

  
 66 








 (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 7.10 because the Indemnitee had an interest in the transaction with respect to which the indemnification applies if the transaction was otherwise permitted by the terms of this
Agreement with respect to the indemnifying Series. 
 (g) The provisions of this Section 7.10 are for the
benefit of the Indemnitees, their heirs, successors, assigns and administrators and shall not be deemed to create any rights for the benefit of any other Persons. 

(h) No amendment, modification or repeal of this Section 7.10 or any provision hereof shall in any manner terminate,
reduce or impair the right of any past, present or future Indemnitee to be indemnified by a Series, nor the obligations of such Series to indemnify any such Indemnitee under and in accordance with the provisions of this Section 7.10 as in
effect immediately prior to such amendment, modification or repeal with respect to Claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such Claims may arise
or be asserted. 
 (i) The provisions of this Section 7.10 shall not be construed to limit the power of any
Series to indemnify an Indemnitee of such Series to the fullest extent permitted by law or to enter into specific agreements, commitments or arrangements for indemnification permitted by law. The absence of any express provision for indemnification
herein shall not limit any right of indemnification existing independently of this Section 7.10. 
 Section 7.11
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 7.11 shall be made (i) only out of the assets of the Indemnifying Series, it being agreed that, except as provided in Section 11.7, no Partner shall be personally liable for such
indemnification nor shall any Partner have any obligation to contribute or loan any monies or property to the Indemnifying Series to enable it to effectuate such indemnification and (ii) only to the extent that the Partners of the Indemnified
Series have not received a payment from the Partners of the Indemnifying Series under Section 6.2(c), 6.3(c), or 6.4(c) 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. 
 (b) Subject to its obligations and duties as a Managing General
Partner set forth in this Agreement, each Managing General Partner may exercise any of the powers granted to it by this Agreement and perform any of the duties imposed upon it hereunder either directly or by or through its agents, and such Managing
General Partner shall not be responsible for any misconduct or negligence on the part of any such agent appointed by such Managing General Partner in good faith. 

(c) To the extent that, at law or in equity, an Indemnitee has duties (including fiduciary duties) and liabilities
relating thereto to the Partnership, any Series or the Partners, the General Partners and any other Indemnitee acting in connection with the Partnership’s or a Series’ business or affairs shall not be liable to the Partnership, such Series
or any Partner for its good faith reliance on the provisions of this Agreement. The provisions of this Agreement, to the extent that they restrict or eliminate the duties and liabilities of a Partner or other Person to the parties hereto otherwise
existing at law or in equity, are agreed by the parties hereto to replace such other duties and liabilities of such Partner or other Person. 
 (d) Any amendment, modification or repeal of this Section 7.12 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 7.12 as in effect immediately prior to such amendment, modification or repeal with respect to Claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal,
regardless of when such Claims may arise or be asserted. 
 Section 7.13 Limitation of Liability. 

The Limited Partners shall have no liability under this Agreement except as expressly provided in this Agreement or the
Delaware Act. A General Partner of a Series shall not be liable for the obligations of the Partnership generally or any other Series solely as a result of its status as a General Partner of a Series, and a General Partner of the Partnership
generally shall not be liable for the obligations of any Series solely as a result of its status as a General Partner of the Partnership generally. 
 Section 7.14 Management of Business. 
 No Limited
Partner, in its capacity as such, shall participate in the operation, management or control (within the meaning of the Delaware Act) of the Partnership’s or any Series’ business, transact any business in the Partnership’s or any
Series’ name or have the power to sign documents for or otherwise bind the Partnership or any Series. Any action taken by any Affiliate 

  
 68 








 
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.

Limited Partners. 
 Notwithstanding any duty otherwise existing at law or in equity, except as otherwise set
forth in any other agreement to which a Partner is a party, including the Omnibus Agreement, any Partner of the Partnership generally or any Series shall be entitled to and may have business interests and engage in business activities in addition to
those relating to the Partnership or any Series, including business interests and activities in direct competition with the Partnership or any Series. 
 Section 7.16 Reliance by Third Parties. 

Notwithstanding anything to the contrary in this Agreement, (a) any Person dealing with the Partnership shall be
entitled to assume that the Managing General Partner of the Partnership generally, and any officer of such Managing General Partner authorized by such Managing General Partner to act on behalf of and in the name of the Partnership, has full power
and authority to encumber, sell or otherwise use in any manner any and all assets of the Partnership generally, and to enter into any authorized contracts on behalf of the Partnership as a whole and the Partnership generally, and such Person shall
be entitled to deal with such Managing General Partner or any such officer as if it were the Partnership’s sole party in interest, both legally and beneficially and (b) any Person dealing with any Series shall be entitled to assume that
the Managing General Partner of such Series, and any officer of such Managing General Partner authorized by such Managing General Partner to act on behalf of and in the name of such Series, has full power and authority to encumber, sell or otherwise
use in any manner any and all assets of such Series and to enter into any authorized contracts on behalf of such Series and such Person shall be entitled to deal with such Managing General Partner or any such officer as if it were such Series’
sole party in interest, both legally and beneficially. Each Limited Partner hereby waives, to the fullest extent permitted by law, any and all defenses or other remedies that may be available against such Person to contest, negate or disaffirm any
action of any Managing General Partner or any such officer in connection with any such dealing. In no event shall any Person dealing with any Managing General Partner or any such officer or its representatives be obligated to ascertain that the
terms of this Agreement have been complied with or to inquire into the necessity or expedience of any act or action of such Managing General Partner or any such officer or its representatives. Each and every certificate, document or other instrument
executed on behalf of the Partnership or any Series by the Managing General Partner of the Partnership generally or such Series, respectively, or its respective representatives shall be conclusive evidence in favor of any and every Person relying
thereon or claiming thereunder that (a) at the time of the execution and delivery of such certificate, document or instrument, this Agreement was in full force and effect, (b) the Person executing and delivering such certificate, document
or instrument was duly authorized and empowered to do so for and on behalf of the Partnership or such Series and (c) such certificate, document or instrument was duly executed and delivered in accordance with the terms and provisions of this

Managing General Partner or any of its Affiliates shall act in a manner that is, or provides terms that are, fair and reasonable to the Partnership or any Partner or any Affiliate thereof, such Managing General Partner shall resolve such conflict of
interest, take such action or provide such terms, considering in each case the relative interest of each party (including its own interest) to such conflict, agreement, transaction or situation and the benefits and burdens relating to such

therewith. Each Partner agrees to cooperate with the Tax Matters Partner and to do or refrain from doing any or all things reasonably required by the Tax Matters Partner to conduct such proceedings. 

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

(d) No Partner shall file a request pursuant to Code Section 6227 for an administrative adjustment of Partnership

 Section 9.5 Withholding. 

The Managing General Partner of the Partnership generally is authorized to take any action that may be required to cause
the Partnership or any Series to comply with any withholding requirements established under the Code or any other federal, state or local law, including pursuant to Sections 1441, 1442, 1445 and 1446 of the Code. To the extent that the Partnership
or any Series is required or elects to withhold and pay over to any taxing authority any amount resulting from the allocation or distribution of income to any Partner (including by reason of Section 1446 of the Code), the Managing General
Partner of the Partnership generally or of the applicable Series may treat the amount withheld as a distribution of cash pursuant to Section 6.2, Section 6.3 or Section 6.4, as applicable, in the amount of such withholding from such
Partner. 
 Section 9.6 Tax Reimbursement. 

If Texas law requires the Partnership or a Series and any Partner both to participate in the filing of a Texas franchise
tax combined group report, and if such Partner or any other member of the Partner’s combined group pays the franchise tax liability due in connection with such combined report, the parties agree that the Partnership or the applicable Series
shall promptly reimburse such Partner for the franchise tax paid on behalf of the Partnership as a combined group member. The franchise tax paid on behalf of the Partnership with respect to each applicable Series shall equal the excess, if any, of
(i) the franchise tax that the combined group including the Partnership pays over (ii) the amount the combined group would have paid if it had computed its franchise tax liability for the report period without the Partnership as a member
of the combined group, but in no event more than what the Partnership or each applicable Series would have paid had it filed the franchise tax return not as a member of a group. In such event, the parties agree that such Partner shall be considered
as paying such amount on behalf of the Partnership with respect to each applicable Series and the Partnership with respect to each applicable Series shall deduct for U.S. federal income tax purposes 100% of the Texas franchise tax attributable to
the Partnership with respect to each applicable Series; provided that in the event that such deduction may not be properly taken by the Partnership with respect to each applicable Series, the Partnership with respect to each applicable Series
shall reimburse such Partner for the after-tax cost of such payment of Texas franchise tax paid on the Partnership’s behalf. 
 Section 9.7 Tax Partnership. 
 It is the intention of
the Partners that the Partnership be classified as a partnership for U.S. federal tax purposes. Neither the Partnership nor any Partner shall make an election for the Partnership or any Series to be excluded from the application of the provisions of
subchapter K of chapter 1 of subtitle A of the Code or any similar provisions of applicable state or local law or to be classified as other than a partnership pursuant to Treasury Regulation Section 301.7701-3 or any similar provision of state
or local law.

delegation being referred to herein as the “Maximum Permitted Delegation”), subject to termination only in the sole discretion of EECI AC Sub or EECI EA Sub, as applicable. Notwithstanding the delegation provided for in this
Section 10.1(a), no Managing General Partner shall be deemed to have withdrawn as a General Partner of the Partnership generally or the applicable Series, and such Managing General Partner shall retain all of its Partnership Interests and
Percentage Interests in the Partnership generally and the applicable Series (as the case may be), and none of the foregoing shall be deemed to have been assigned or transferred to EECI AC Sub or EECE EA Sub (or their designees), as applicable.

 (b) If all or a portion of the Maximum Permitted Delegation is determined to be invalid or unenforceable for
any reason following a Fundamental Change, EECI, in its sole discretion, may elect to become the Managing General Partner of the Series AC, the Series EA and each Alberta Clipper Expansion Series by providing five Business Days’ prior
written notice of such election to the Managing General Partner of the Partnership generally at any time (such election, the “Control Option”). Upon exercise of the Control Option: 

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

(ii) EECI AC Sub shall be granted a General Partner Interest in each Alberta Clipper Expansion Series that shall have no
economic rights with respect to such Series or otherwise; 
 (iii) EECI AC Sub shall automatically become the
Managing General Partner of the Series AC and each Alberta Clipper Expansion Series, and EECI EA Sub shall automatically become the Managing General Partner of the Series EA, in each case, with all rights, powers and obligations of the Managing
General Partner of such Series as set forth in this Agreement; and 

  
 75 








 (iv) all rights, powers and obligations of the existing Managing General
Partner of the Series AC, Series EA and each Alberta Clipper Expansion Series (in its capacity as such) shall immediately terminate. 
 The exercise of the Control Option pursuant to this Section 10.1(b) shall not affect (A) the status of any Managing General Partner of the Partnership generally or any Series (other than the
Series AC, Series EA or an Alberta Clipper Expansion Series) or (B) the Percentage Interest of the Series AC Partners, the Series EA or the Partners of any Alberta Clipper Expansion Series. 

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

  
 76 








 
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 EECI AC 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 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 AC Sub and Lakehead GP are able to agree on such allocation arrangement,
then the Series AC Revenue Entitlement and Series AC Expenses will be calculated in accordance with such arrangement. If EECI AC 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 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 AC Sub and Lakehead GP are unable to agree on an allocation arrangement pursuant to
Section 10.2(c), such allocation arrangement shall be determined through binding arbitration using three arbitrators, in accordance with the Commercial Arbitration Rules of the American Arbitration Association, as supplemented to the extent
necessary to determine any procedural appeal questions by the Federal Arbitration Act (Title 9 of the United States Code). If there is any inconsistency between this Section 10.2(d) and the Commercial Arbitration Rules or the Federal
Arbitration Act, the terms of this Section 10.2(d) will control the rights and obligations of the parties. Arbitration shall be initiated 180 days prior to the expiration of the Alberta Clipper Surcharge Term. Each of EECI AC Sub 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 AC 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 AC 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 AC Sub and Lakehead GP shall exchange in writing, signed by the respective parties, their respective 

  
 77 








 
proposed allocation arrangements. At the conclusion of the hearing, the arbitrators shall choose either the allocation arrangement of EECI AC Sub or the allocation arrangement of Lakehead GP, and
shall have no power or authority whatsoever to reach any other result. In making their choice, the arbitrators shall choose the allocation arrangement that in their judgment most equitably allocates the total Lakehead System revenues in a manner
that best represents the relative economic value of each Series as of the expiration of the Alberta Clipper Surcharge Term. EECI AC Sub, Lakehead GP and the arbitrators shall proceed diligently and in good faith in order that the determination may
be made as promptly as possible. Except as provided in the Federal Arbitration Act, the decision of the arbitrators will be binding on and non-appealable by the parties. 
 Section 10.3 Eastern Access Surcharge Expiration. 

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

(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


  
 78 








 
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 10.3(d) and the Commercial Arbitration Rules or the Federal Arbitration Act, the terms of this Section 10.3(d) will control the rights
and obligations of the parties. Arbitration shall be initiated 180 days prior to the expiration of the applicable Series EA Tariff Term Sheet. Each of EECI EA Sub and Lakehead GP shall appoint an arbitrator at least 150 days prior to the expiration
of the applicable Series EA Tariff Term Sheet. 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 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. 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 applicable Series EA Tariff Term Sheet. EECI EA Sub, Lakehead GP and the arbitrators shall proceed diligently and in good faith
in order that the determination may be made as promptly as possible. Except as provided in the Federal Arbitration Act, the decision of the arbitrators will be binding on and non-appealable by the parties. 

(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.

 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 7.3(q) and Section 7.4(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; 
 (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, agree in writing or vote to continue the business of the Partnership and to the appointment, effective as of the date of such event, if
required, of one or more additional general partners of the Partnership generally and, to the extent applicable, each Series. 
 (b) Upon the dissolution of the Partnership as provided herein, the Partnership shall be wound up by winding up each Series in the manner provided by Section 11.3. 

Section 11.2 Termination of a Series. 

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

(i) the dissolution of the Partnership; 

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

 (iii) subject to Section 7.3(q) and Section 7.4(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 Series EA Partnership Interests, in the case of Series EA; 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, 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. 

  
 80 








 (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. 

  
 81 








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

  
 82 








 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. 

ARTICLE XII

 MEETINGS; RECORD DATE; MERGER 
 Section 12.1 Amendment. 

Except as otherwise provided by this Agreement, this Agreement may be amended by the Managing General Partner of the
Partnership generally in writing without the approval of any other Partner; provided that the provisions of Section 7.10 shall not be amended in any way that would adversely affect an Indemnitee without the consent of such Indemnitee.

 Section 12.2 Amendment Requirements. 

Notwithstanding the provisions of Section 12.1, no provision of this Agreement that establishes a Percentage Interest
required to take any action with respect to any Series shall be amended, altered, changed, repealed or rescinded in any respect that would have the effect of reducing such voting percentage unless such amendment is approved by the written consent or
the affirmative vote of holders of Partnership Interests of such Series whose aggregate Percentage Interests constitute not less than the voting requirement sought to be reduced. 

Section 12.3 Voting Rights. 
 Unless otherwise required by the Delaware Act or this Agreement, all actions, approvals and consents to be taken or given by the Partners of a Series under the Delaware Act, this Agreement or otherwise
shall require the affirmative vote or written consent of a Majority in Interest of the Partnership Interests of such Series, in the case of the Series AC and Series LH, or a Supermajority Interest of the Series EA Partnership Interests, in the case
of Series EA, 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 Series EA Partnership
Interests. 
 Section 12.4 Meetings. 

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

  
 83 








 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 Series EA Partnership Interests, in the case of Series EA, 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 Series EA Partnership Interests, in the case of Series EA, 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. 

  
 84 








 Section 12.8 Proxies. 

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

Section 12.9 Action Without a Meeting. 

Any action required or permitted to be taken at a meeting of Partners of any Series may be taken without a meeting and
without prior notice if the Managing General Partner of such Series receives written consents by the Partners of such Series representing the minimum number of votes that would be necessary to authorize or to take such action at a meeting at which
all Partners of such Series were present and voted. 
 Section 12.10 Waiver of Notice. 

When any notice is required to be given to any Partner, a waiver thereof in writing signed by the Partner entitled to such
notice, whether before, at or after the time stated therein, or the presence and participation of such Partner in a meeting, or the participation by such Partner in a meeting by conference telephone or similar communications equipment, shall be
equivalent to the giving of such notice. 
 Section 12.11 Merger, Consolidation and Conversion. 

(a) Subject to Section 7.3 and 7.4, 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. 

(b) Pursuant to Section 17-211(g) of the Delaware Act, an agreement of merger or consolidation approved in
accordance with this Section 12.11 may (i) effect any amendment to this Agreement or (ii) effect the adoption of a new partnership agreement for the Partnership. Any such amendment or adoption made pursuant to this Section 12.11
shall be effective at the effective time or date of the merger or consolidation. 
 (c) The Managing General
Partner of the Partnership generally shall have the authority to convert the Partnership to a Delaware statutory trust if, on the advice of counsel, such conversion (i) is necessary and advisable for Wisconsin GP to have or retain condemnation
authority under Wisc. Stat. § 32.01, et seq. and (ii) would not result in a default under any Indebtedness of the Partnership or Enbridge Partners existing at such time; provided that (A) the


  
 85 








 
trust is structured as a series trust pursuant to Del. Code tit. 12, § 3801, et seq., (B) the relative rights and obligations of the Partners of each Series are maintained in the
trust (and each series thereof), (C) the beneficial owners of each series of the trust own an undivided beneficial interest in all of the assets of the Series of which they are beneficial owners, (D) the trust would be disregarded for U.S.
federal income tax purposes and (E) the limited liability of the beneficial owners of the trust (and each series thereof) would be expected to be respected in all relevant states to the same extent as that applicable to limited partners of a
Delaware limited partnership.

the Shared Assets (each, a “Capital Improvement Project”). Any such requests shall specify in reasonable detail the Capital Improvement Project, any permits that may be required, the estimated cost of such Capital Improvement
Project, any proposed changes to this Exhibit D, and any other relevant information relating to such Capital Improvement Project. Each Series agrees that it will consider in good faith any such request, but a Series shall have no obligation

responsibility for all costs associated with such Capital Improvement Project. 

  
 Exhibit D-5








 (b) A rejecting Series (the “Rejecting Series”) shall
provide to each other Series a written explanation for the rejection of any request to undertake a Capital Improvement Project. If the Improvement Series, together with any other Series that does not reject the request to undertake the Capital
Improvement Project (collectively, the “Non-Rejecting Series”), desires to undertake a Capital Improvement Project relating to the Shared Assets despite the Rejecting Series’ rejection, then the Non-Rejecting Series
(i) may undertake such Capital Improvement Project, (ii) shall share the entire cost and Liability associated with such Capital Improvement Project, (iii) shall be entitled to all the benefits and rights of use associated with such
Capital Improvement Project and (iv) shall develop such Capital Improvement Project in a manner that does not interfere unreasonably with the operations of any Rejecting Series or the Partnership generally.
