ESTABLISHMENT AND DESIGNATION OF SERIES

 

Section
3.1           Establishment and Designation of Series.

 

(a)          Prior to the
Series L3R Closing Date, the partnership interests in the Partnership were divided into four series referred to as the “Series
AC,” the “Series EA,” the “Series ME” and the “Series LH.” As of the Series L3R Closing
Date, the Partners hereby establish a fifth series of partnership interests in the Partnership referred to as the “Series
L3R.” Each Series shall constitute a separate series of partnership interests in accordance with Section 17-218 of the
Delaware Act, having separate rights, powers, duties and obligations as set forth herein, with each such Series comprised of both
General Partner Interests and Limited Partner Interests, as set forth in Article V.

 

    	35

     

    

 

(b)          Each Series
shall be separate and distinct from each other Series, and separate and distinct records shall be maintained for each Series. The
records maintained for each Series shall account for the assets and Liabilities associated with such Series separately from the
assets and Liabilities associated with any other Series or the Partnership generally. Records maintained for a Series that reasonably
identify its assets, including by specific listing, category, type, quantity, computational or allocational formula or procedure
(including a percentage or share of any asset or assets) or by any other method where the identity of such assets is objectively
determinable, will be deemed to account for the assets associated with such Series separately from the assets associated with any
other Series. Except for the Intercompany Obligations and the Springing Guarantees or as may be expressly agreed to by a Series
or the Partnership generally, no Liability of a Series shall be a Liability of any other Series or the Partnership generally. To
the fullest extent permitted by applicable law, except for the Intercompany Obligations and the Springing Guarantees or as may
be expressly agreed to by a Series or the Partnership generally, all of the Liabilities incurred, contracted for or otherwise now
or hereafter existing with respect to a particular Series shall be enforceable against the assets of such Series only or a General
Partner associated with such Series and not against the assets of any other Series or of the Partnership generally or any General
Partner not associated with such Series, and, except for the Intercompany Obligations and the Springing Guarantees or as may be
expressly agreed to by a Series or the Partnership generally, none of the Liabilities incurred, contracted for or otherwise existing
with respect to any other Series shall be enforceable against the assets of such Series. The Certificate of Limited Partnership
shall contain a notice of the limitation of liabilities of the Series and of the Partnership generally in conformity with Section 17-218
of the Delaware Act.

 

(c)          Each Series
shall have the power and capacity to, in its own name, contract, hold title to assets (including real, personal and intangible
property), grant liens and security interests and sue and be sued.

Obligations or Springing Guarantees) contractually created or incurred or amended by any Series following the Series AC Closing

all contracts of a Series (other than contracts relating to any Intercompany Obligations or Springing Guarantees) entered into
or amended after the Series AC Closing Date, (i) expressly acknowledge the separateness of the Partnership generally and each
Series, (ii) notify the contract counterparty of the identity of the obligor or obligors thereunder (and if more than one

and/or such Series, as applicable.

 

(c)          The Partners
(in their respective capacities as such) on the one hand, and Enbridge Partners (on behalf of itself and each Material Subsidiary
of Enbridge Partners) on the other hand, acknowledge and agree that, for so long as any Existing Indebtedness (or refinancing thereof)
requires, all Intercompany Obligations currently or hereafter existing are expressly recourse to the Partnership generally and
to each Series, and expressly non-recourse to the Partners of the Partnership generally and to the Partners of each Series (in
the case of Partners, in their respective capacities as such). The Managing General Partner of the Partnership generally shall
designate each Intercompany Obligation as the primary obligation of the applicable Series (the “Primary Obligor”)
with respect to which the Intercompany Obligation was incurred. The Series AC will be the Primary Obligor with respect to
the Intercompany Preliminary AC Construction Cost Payable and Facility B1 and Facility C1 and any refinancing thereof,
including the Series AC Long-Term Debt Financing; the Series EA will be the Primary Obligor with respect to the Intercompany
Preliminary EA Construction Cost Payable; the Series ME will be the Primary Obligor with respect to the Intercompany Preliminary
ME Construction Cost Payable; the Series L3R will be the Primary Obligor with respect to the Intercompany Preliminary L3R Construction
Cost Payable and the L3R Additional True-Up Amount; and the Series LH will be the Primary Obligor with respect to all other
Intercompany Obligations. As among each Series of the Partnership and the Partnership generally, the Primary Obligor with respect
to an Intercompany Obligation shall have the primary responsibility for administering and discharging such obligation and shall
have primary liability to the creditors or other obligees associated with such obligation.

 

(d)          The Managing
General Partner of the Partnership generally shall determine the portion of the Liabilities associated with or arising from the
use, ownership or operation of the Shared Assets to be designated as Series AC Liabilities, Series EA Liabilities, Series ME Liabilities,
Series L3R Liabilities or Series LH Liabilities (with respect to each Series, its “Proportionate Share of Shared Liabilities”)
based on the following criteria (and the Managing General Partners of the Series AC, Series EA, Series ME, Series L3R and
the Series LH shall maintain the Series AC Records, the Series EA Records, the Series ME Records, the Series L3R Records
and the Series LH Records, respectively, in a manner consistent with such determination):

 

(i)          the
relative use by the Series AC, Series EA, Series ME, Series L3R and Series LH of the Shared Asset to which the Liability
relates;

 

(ii)         the
relative benefit to the Series AC, Series EA, Series ME, Series L3R and Series LH of the Shared Asset to which the Liability
relates; and

 

    	40

     

    

 

(iii)        if
applicable, the relative fault of the Series AC, Series EA, Series ME, Series L3R and Series LH with respect to the activities
or events giving rise to the Liability related to such Shared Asset.

 

Section
3.8           No Transfer or Sale.

 

The Partners acknowledge
and agree that neither the establishment of the Series AC, Series EA, Series ME, Series L3R and Series LH, nor the designation
of their respective assets as set forth in this Article III shall constitute a sale, transfer or other disposition of any asset
of the Partnership.

 

ARTICLE
IV

TRANSFER OF PARTNERSHIP INTERESTS;

RIGHT OF FIRST REFUSAL; TAG-ALONG RIGHTS

 

Section
4.1            Transfers Generally.

 

(a)          Transfers of
Partnership Interests may only be made in strict compliance with all applicable terms of this Agreement, and any purported Transfer
of Partnership Interests that does not so comply with all applicable provisions of this Agreement shall, to the fullest extent
permitted by law, be null and void and of no force or effect, and no Managing General Partner acting on behalf of the Partnership
generally or any Series shall recognize or be bound by any such purported Transfer or effect any such purported Transfer on the
transfer books of the 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 Section 4.1(b) and this Section 4.1(c), without the
consent of any other Partner being required.

 

    	41

     

    

 

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

 

Section
4.2           General Restrictions on Transfers of Partnership Interests.

 

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

 

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

 

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

 

Section
4.3           Additional Restrictions on Transfers of Partnership Interests.

 

(a)          Series EA,
Series ME and Series L3R Partnership Interests. No Transfer of a Series EA, Series ME or Series L3R Partnership Interest may
be made unless (i) such Transfer complies with the provisions of Section 4.1 and Section 4.2 and (ii) unless
such Transfer is to a Permitted Transferee of the transferring Partner, such Transfer is made in accordance with Sections 4.5,
4.6, 4.7 or 4.8, as applicable.

 

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

 

    	42

     

    

 

Section
4.4           Reserved.

 

Section
4.5           Series EA Right of First Refusal.

 

(a)          If any Partner
receives a bona fide written offer from a Third Party (a “Third Party Offer”) for the Transfer of all or a part
of such Partner’s (and its respective Permitted Transferees) Partnership Interests in Series EA and such Partner (the “EA
Offering Partner”) desires to accept and is otherwise permitted to effect such proposed Transfer pursuant to this
Article IV, such EA Offering Partner shall deliver written notice of such Third Party Offer (the “EA ROFR
Notice”) to the Managing General Partner of the Partnership generally as soon as reasonably practicable, but in no event
less than 35 days prior to the date of the proposed Transfer. The date that the EA ROFR Notice is received by the Managing General
Partner of the Partnership generally shall constitute the “EA ROFR Notice Date.” Within five Business Days following
the EA ROFR Notice Date, the Managing General Partner of the Partnership generally shall send a copy of the EA ROFR Notice along
with a letter indicating the EA ROFR Notice Date to EECI and Enbridge Partners (each, a “ROFR Holder” and collectively,
the “ROFR Holders”). The EA ROFR Notice shall set forth the identity of the Third Party (including, (x) if
such information is not publicly available, information about the identity of the Third Party, (y) the identity of Affiliates
of the Third Party and (z) if the Third Party is making the Third Party Offer as a nominee of another Person, the identity of such
other Person and its Affiliates), the amount and the Partnership Interests to be sold (the “EA Offered Interests”),
the proposed purchase price for the EA Offered Interests (the “EA ROFR Offer Price”), all details of
the payment terms and all other material terms and conditions, including the nature of the representations and warranties to be
made and the indemnities to be given, in connection with the proposed Transfer. The EA ROFR Offer Price shall be expressed in U.S.
dollars, whether or not the form of consideration in the Third Party Offer is wholly or partially cash or cash equivalents.

 

(b)          Each ROFR Holder
shall have the right, but not the obligation, to purchase up to that amount of the EA Offered Interests equal to the product of
(i) the amount of the EA Offered Interests and (ii) a fraction (the “EA ROFR Proportionate Share”),
the numerator of which shall be the Series EA Percentage Interest of such ROFR Holder and the denominator of which shall be the
sum of the Series EA Percentage Interests held by the ROFR Holders. Within 25 days after the EA ROFR Notice Date, each ROFR Holder
may deliver a written notice to the EA Offering Partner, the Managing General Partner of the Partnership generally and the other
EA ROFR Holder of its election to purchase such EA Offered Interests. Any ROFR Holder whose written notice has not been received
by the Managing General Partner of the Partnership generally within such 25-day period shall be deemed to have elected not to exercise
its right of first refusal in connection with such Transfer. To the extent a ROFR Holder does not elect to purchase its full EA
ROFR Proportionate Share of such EA Offered Interests, the other ROFR Holder, if it has elected to purchase its full EA ROFR Proportionate
Share, shall be entitled, by delivering written notice to the EA Offering Partner and the Managing General Partner of the Partnership
generally within five Business Days following the end of such 25-day period (such fifth Business Day, the “EA ROFR
Expiration Date”), to purchase up to all of the remaining EA Offered Interests. The delivery of a notice of election
under this Section 4.5(b) shall constitute an irrevocable commitment to purchase such EA Offered Interests. If the ROFR Holders
shall have elected to purchase all but not less than all of the EA Offered Interests, the Managing General Partner of the Partnership
generally shall thereafter set a reasonable place and time for the closing of the purchase and sale of the EA Offered Interests,
which shall be not less than 10 days nor more than 60 days after the EA ROFR Expiration Date (subject to extension to the extent
necessary to pursue any required regulatory or Partner approvals, including to allow for the expiration or termination of all waiting
periods under the HSR Act) unless otherwise agreed by all of the parties to such transaction.

 

    	43

     

    

 

(c)          The purchase
price and terms and conditions for the purchase of the EA Offered Interests pursuant to this Section 4.5 shall be the purchase
price and terms and conditions set forth in the applicable Third Party Offer (or the cash equivalent thereof); provided
that the purchase price shall be the EA ROFR Offer Price and shall be payable in immediately available U.S. dollars; and provided
further that the EA Offering Partner shall at a minimum make customary representations and warranties concerning (i) such
EA Offering Partner’s valid title to and ownership of the EA Offered Interests, free and clear of all liens, claims and encumbrances
(excluding those arising hereunder and under applicable securities laws), (ii) such EA Offering Partner’s authority,
power and right to enter into and consummate the sale of the EA Offered Interests, (iii) the absence of any violation, default
or acceleration of any agreement or obligation to which such EA Offering Partner is subject or by which its assets are bound as
a result of the sale of the EA Offered Interests and (iv) the absence of, or compliance with, any governmental or third party
consents, approvals, filings or notifications required to be obtained or made by such EA Offering Partner in connection with the
sale of the EA Offered Interests. The EA Offering Partner and participating ROFR Holders shall use commercially reasonable efforts
to close the purchase of the EA Offered Interests as soon as reasonably practicable following the EA ROFR Expiration Date and shall
each execute and deliver such instruments and documents and take such actions, including obtaining all applicable approvals and
consents and making all applicable notifications and filings, as the other parties may reasonably request in order more effectively
to implement the purchase and sale of the EA Offered Interests hereunder.

 

(d)          Notwithstanding
the foregoing, if (i) the ROFR Holders (A) shall have elected to purchase less than all of the EA Offered Interests or
(B) shall not have elected to purchase any of the EA Offered Interests on or prior to the EA ROFR Expiration Date, and the
EA Offering Partner has fully complied with the provisions of this Section 4.5, then the EA Offering Partner may sell all,
but not less than all, of the EA Offered Interests within 90 days after the EA ROFR Expiration Date (subject to extension for a
reasonable amount of time to the extent necessary to obtain any required regulatory or Partner approvals, including to allow for
the expiration of all waiting periods under the HSR Act) or (ii) if the ROFR Holders fail to consummate the closing of the
purchase and sale of the Offered Interests within the time period provided in the last sentence of Section 4.5(b) (such period,
the “EA ROFR Closing Period”) and the EA Offering Partner has fully complied with the provisions of this
Section 4.5, then the EA Offering Partner may sell all, but not less than all, of the EA Offered Interests within 90 days
after the expiration of the EA ROFR Closing Period to the Third Party, in each case subject to the provisions of Section 4.2.
Any such sale shall not be at less than the purchase price or upon terms and conditions more favorable in any material respect,
individually or in the aggregate, to the purchaser than those specified in the Third Party Offer. If the EA Offered Interests are
not so transferred within the applicable time periods specified in this Section 4.5(d), the EA Offering Partner may not sell
any of the EA Offered Interests without again complying in full with the provisions of this Article IV.

 

    	44

     

    

 

(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

(a)          If any Partner
receives a Third Party Offer for the Transfer of all or a part of such Partner’s (and its respective Permitted Transferees)
Partnership Interests in Series ME and such Partner (the “ME Offering Partner”) desires to accept and
is otherwise permitted to effect such proposed Transfer pursuant to this Article IV, such ME Offering Partner shall deliver
written notice of such Third Party Offer (the “ME ROFR Notice”) to the Managing General Partner of the
Partnership generally as soon as reasonably practicable, but in no event less than 35 days prior to the date of the proposed Transfer.
The date that the ME ROFR Notice is received by the Managing General Partner of the Partnership generally shall constitute the
“ME ROFR Notice Date.” Within five Business Days following the ME ROFR Notice Date, the Managing General Partner
of the Partnership generally shall send a copy of the ME ROFR Notice along with a letter indicating the ME ROFR Notice Date to
the ROFR Holders. The ME ROFR Notice shall set forth the identity of the Third Party (including, (x) if such information is
not publicly available, information about the identity of the Third Party, (y) the identity of Affiliates of the Third Party
and (z) if the Third Party is making the Third Party Offer as a nominee of another Person, the identity of such other Person and
its Affiliates), the amount and the Partnership Interests to be sold (the “ME Offered Interests”), the proposed
purchase price for the ME Offered Interests (the “ME ROFR Offer Price”), all details of the payment terms and
all other material terms and conditions, including the nature of the representations and warranties to be made and the indemnities
to be given, in connection with the proposed Transfer. The ME ROFR Offer Price shall be expressed in U.S. dollars, whether or not
the form of consideration in the Third Party Offer is wholly or partially cash or cash equivalents.

 

(b)          Each ROFR Holder
shall have the right, but not the obligation, to purchase up to that amount of the ME Offered Interests equal to the product of
(i) the amount of the ME Offered Interests and (ii) a fraction (the “ME ROFR Proportionate Share”),
the numerator of which shall be the Series ME Percentage Interest of such ROFR Holder and the denominator of which shall be the
sum of the Series ME Percentage Interests held by the ROFR Holders. Within 25 days after the ME ROFR Notice Date, each ROFR Holder
may deliver a written notice to the ME Offering Partner, the Managing General Partner of the Partnership generally and the other
ME ROFR Holder of its election to purchase such ME Offered Interests. Any ROFR Holder whose written notice has not been received
by the Managing General Partner of the Partnership generally within such 25-day period shall be deemed to have elected not to exercise
its right of first refusal in connection with such Transfer. To the extent a ROFR Holder does not elect to purchase its full ME
ROFR Proportionate Share of such ME Offered Interests, the other ROFR Holder, if it has elected to purchase its full ME ROFR Proportionate
Share, shall be entitled, by delivering written notice to the ME Offering Partner and the Managing General Partner of the Partnership
generally within five Business Days following the end of such 25-day period (such fifth Business Day, the “ME ROFR Expiration
Date”), to purchase up to all of the remaining ME Offered Interests. The delivery of a notice of election under this
Section 4.6(b) shall constitute an irrevocable commitment to purchase such ME Offered Interests. If the ROFR Holders shall
have elected to purchase all but not less than all of the ME Offered Interests, the Managing General Partner of the Partnership
generally shall thereafter set a reasonable place and time for the closing of the purchase and sale of the ME Offered Interests,
which shall be not less than 10 days nor more than 60 days after the ME ROFR Expiration Date (subject to extension to the extent
necessary to pursue any required regulatory or Partner approvals, including to allow for the expiration or termination of all waiting
periods under the HSR Act) unless otherwise agreed by all of the parties to such transaction.

that the purchase price shall be the ME ROFR Offer Price and shall be payable in immediately available U.S. dollars; and provided
further that the ME Offering Partner shall at a minimum make customary representations and warranties concerning (i) such
ME Offering Partner’s valid title to and ownership of the ME Offered Interests, free and clear of all liens, claims and encumbrances

any of the ME Offered Interests without again complying in full with the provisions of this Article IV.

its Partnership Interests in Series EA, Series ME or Series L3R to a Third Party (the “Tag-Along Transferee”),
then such Transferor shall send written notice of such proposed Transfer (the “Tag-Along Notice”) to the other
Partners of the Series of Partnership Interests which such Transferor proposes to Transfer (the “Tag Offerees”)
at least 30 days prior to effecting such Transfer. Such Tag-Along Notice may be combined with an EA ROFR Notice, ME ROFR Notice
or L3R ROFR Notice and may be conditioned upon the ROFR Holders not exercising the right of first refusal contained in Section
4.5, Section 4.6 or Section 4.7. The Tag-Along Notice shall set forth the identity of the Tag-Along Transferee (including, if such
information is not publicly available, information about the identity of the Tag-Along Transferee and its Affiliates), the amount
and the Partnership Interests to be Transferred, the proposed purchase price expressed in U.S. dollars (whether or not the form
of consideration is wholly or partially cash or cash equivalents), all details of the payment terms, the time and place for the
closing and all other material terms and conditions, including the nature of the representations and warranties to be made and
the indemnities to be given, in connection with the proposed Transfer. Each of the Tag Offerees shall then have the irrevocable
right (a “Tag-Along Right”), exercisable by delivery of an irrevocable notice to the Transferor at any time
within 20 days after receipt of the Tag-Along Notice, to participate in such Transfer by selling to the Tag-Along Transferee a
pro rata portion of such Tag Offeree’s Partnership Interests in Series EA, Series ME or Series L3R, as applicable, based
on the respective Tag Pro Rata Share of the Transferor and the other Tag Offerees that exercise their Tag-Along Right, on the same
terms (including with respect to representations, warranties and indemnification) as the Transferor; provided, however,
that (i) any representations and warranties relating specifically to any such Tag Offeree shall only be made by such Tag Offeree;
(ii) any indemnification provided by the Transferor and any such Tag Offeree (other than with respect to the representations
referenced in the foregoing subsection (i)) shall be based on the Percentage Interest being sold by each party in the proposed
sale, either on a several, not joint, basis or solely with recourse to an escrow (such escrow not to exceed 25% of the proceeds
received by the Tag Offerees that exercise their Tag-Along Right without the consent of such Tag Offerees) established for the
benefit of the proposed purchaser (each party’s contributions to such escrow to be on a pro rata basis in accordance with
the proceeds received from such sale), it being understood and agreed that any such indemnification obligation of any such Tag
Offeree shall in no event exceed the net proceeds to such Tag Offeree from such proposed Transfer; and (iii) the form of consideration
to be received by the Transferor in connection with the proposed sale shall be the same as that received by such Tag Offeree.

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

 

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

 

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

 

Section
4.9           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 4.9, 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.

 

    	50

     

    

 

(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 4.9 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 4.9 shall be the purchase
price and terms and conditions set forth in the applicable Third Party Asset Offer; provided that the purchase price shall
be the ROFR Asset Offer Price and shall be payable in immediately available U.S. dollars; and provided further that the
applicable Series shall at a minimum make customary representations and warranties concerning (i) the Series’ valid
title to and ownership of the ROFR Offered Asset, free and clear of all liens, claims and encumbrances (excluding those arising
hereunder and under applicable securities laws), (ii) the Series’ authority, power and right to enter into and consummate
the sale of the ROFR Offered Asset, (iii) the absence of any violation, default or acceleration of any agreement to which
the Series is subject or by which its assets are bound as a result of the agreement to sell and the sale of the ROFR Offered Asset
and (iv) the absence of, or compliance with, any governmental or third party consents, approvals, filings or notifications
required to be obtained or made by the Series in connection with the sale of the ROFR Offered Asset. The Managing General Partner
of such Series and EECI shall use commercially reasonable efforts to close the purchase of the ROFR Offered Asset as soon as reasonably
practicable following the giving of the ROFR Asset Notice and shall execute and deliver such instruments and documents and take
such actions, including obtaining all applicable approvals and consents and making all applicable notifications and filings, as
the other party may reasonably request in order more effectively to implement the purchase and sale of the ROFR Offered Asset hereunder.

 

    	51

     

    

 

(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 4.9, 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 4.9(b) (such period, the “ROFR Asset Closing Period”) and the Series has fully complied
with the provisions of this Section 4.9, then EECI shall not have the right to purchase the ROFR Offered Asset, and the Series
may sell the ROFR Offered Asset within 90 days after the expiration of the ROFR Asset Closing Period, in each case subject to the
provisions of Section 7.3, Section 7.4 and Section 7.5, as applicable. Any such sale shall not be at less than the purchase
price or upon terms and conditions more favorable in any material respect, individually or in the aggregate, to the purchaser than
those specified in the Third Party Asset Offer. If the ROFR Offered Asset is not so transferred within the applicable time periods
specified in this Section 4.9(d), the Series may not sell the ROFR Offered Asset without again complying in full with the
provisions of this Section 4.9.

 

(e)          EECI shall be
entitled to assign any rights it has to purchase a ROFR Offered Asset pursuant to this Section 4.9 to any of its Permitted
Transferees.

 

(f)          This Section 4.9
shall not apply to any transfer or proposed transfer of assets to a Permitted Transferee.

(a)          From time to
time prior to the twelve-month anniversary of the Eastern Access Final In-Service Date (the “EA Call Option
Deadline”), Enbridge Partners shall have the right to purchase, and EECI shall have the obligation to sell (the “EA
Call Option”), a portion of the Series EA Limited Partner Interests held by EECI that represents, in the aggregate, up
to fifteen percent (15%) of the total outstanding Series EA Partnership Interests in accordance with this Section 4.10. In considering
whether to exercise the EA Call Option, the Board of Directors of Enbridge Energy Management, L.L.C. (the “EEM Board”)
shall establish a committee of independent directors (an “Option Committee”) to make a recommendation to the
EEM Board, on behalf of Enbridge Partners, whether to exercise the EA Call Option and the portion of Series EA Limited Partner
Interests held by EECI that Enbridge Partners will purchase if the EA Call Option is exercised (not to exceed, in the aggregate,
fifteen (15%) of the total outstanding Series EA Partnership Interests). The general partner of Enbridge Partners and the Managing
General Partner of the Partnership and of each Series shall provide the Option Committee with all of the information that the Option
Committee may reasonably request that is relevant to its determination.

 

    	52

     

    

 

(b)          If the EEM
Board determines to exercise all or a portion of the EA Call Option following receipt of the Option Committee’s recommendation,
Enbridge Partners shall deliver to the Partnership and to EECI, prior to the EA Call Option Deadline, written notice (each, an
“EA Call Option Notice”) of such determination. Each EA Call Option Notice shall state (i) the
portion of the Series EA Limited Partner Interests held by EECI proposed to be purchased (not to exceed, in the aggregate, fifteen
percent (15%) of the total outstanding Series EA Partnership Interests) (an “EA Call Option Interest”)
and the corresponding amount of consideration to be paid, calculated in accordance with Section 4.10(c), (ii) the proposed date
of purchase and (iii) other proposed material terms and conditions of such sale. Upon receipt of each EA Call Option Notice,
EECI agrees to promptly take all necessary and desirable actions in connection with the exercise of the EA Call Option reasonably
requested by Enbridge Partners, including the execution of such agreements and such instruments and other actions reasonably necessary
to consummate the purchase and sale of the EA Call Option Interest hereunder. Each date on which the purchase and sale of an EA
Call Option Interest is consummated is referred to as an “EA Call Option Closing Date.” Such agreements and
instruments shall contain customary representations and warranties concerning (i) EECI’s valid title to and ownership of
the EA Call Option Interest, free and clear of all liens, claims and encumbrances (excluding those arising under this Agreement
and applicable securities laws), (ii) EECI’s authority, power and right to enter into and consummate the sale of the EA Call
Option Interest, (iii) the absence of any violation, default or acceleration of any agreement to which EECI is subject or by which
its Partnership Interests are bound as a result of the agreement to sell and the sale of the EA Call Option Interest, and (iv)
the absence of, or compliance with, any governmental or third party consents, approvals, filings or notifications required to be
obtained or made by EECI in connection with the sale of the EA Call Option Interest. EECI shall execute and deliver such instruments
and documents and take such actions, including obtaining all applicable approvals and consents and making all applicable notifications
and filings, as Enbridge Partners may reasonably request, but neither the failure of EECI to execute or deliver any such documentation
nor the failure of EECI to comply with all required actions shall affect the validity of a purchase and sale pursuant to this Section
4.10.

 

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

 

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

Section
5.6           Additional Series EA Capital Contributions.

 

(a)          (i) Except as
otherwise provided in Section 5.6(a)(ii), 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, except as a result of the operation of Section 5.6(a)(ii), 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.

 

(ii) Commencing with
and including the date on which the Series EA Capital Contribution Notice is delivered to the Series EA Partners in August 2015
and continuing through the earlier of (A) the first date after the date on which the Series EA Distribution is paid with respect
to the Quarter ending March 31, 2016 on which Enbridge Partners has made Additional Series EA Capital Contributions pursuant to
this Section 5.6(a)(ii) in excess of its Pro Rata portion in an amount equal to the Series EA Abatement Amount determined as of
the date immediately following the date on which the Series EA Distribution for the Quarter ending
March 31, 2016 is paid and (B) December 31, 2016, with respect to each Series EA Capital Contribution Notice, Enbridge Partners
shall contribute an amount equal to its Pro Rata portion of any Additional Series EA Capital Contribution plus the Series EA Contribution
Offset Amount, and EECI shall contribute an amount equal to its Pro Rata portion of such Additional Series EA Capital Contribution
less the Series EA Contribution Offset Amount; provided that (1) Enbridge Partners’ contribution with respect to any
such Series EA Capital Contribution Notice shall in no event exceed 100.0% of the Additional Series EA Capital Contributions specified
in such Series EA Capital Contribution Notice and (2) EECI’s contribution with respect to any such Series EA Capital Contribution
Notice shall in no event be less than zero.

 

(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, except as provided in Section 5.6(a)(ii), 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.

 

    	59

     

    

 

(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, except as provided in Section 5.6(a)(ii), shall be an amount
equal to such Series EA Partner’s Pro Rata portion of the total amount of such Additional Series EA Capital Contribution,
(iii) the date on which such Additional Series EA Capital Contribution is due, which shall not be less than 10 Business
Days from the date such notice is delivered and (iv) the Person or the account to which such Additional Series EA Capital
Contribution is to be made.

 

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

 

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

 

    	60

     

    

 

(i)          To the extent
that one or more Non-Defaulting Series EA Partners do not elect to have an advance made pursuant to this Section 5.6(e) treated
as a loan to the Defaulting Series EA Partner, or affirmatively elects to have such advance treated as a Capital Contribution,
the Managing General Partner of the Series EA will automatically adjust the Series EA Percentage Interest of (A) each such
Non-Defaulting Series EA Partner to equal the percentage obtained by dividing (x) the Series EA Capital Account of each such
Non-Defaulting Series EA Partner (including any Capital Contribution made by such Non-Defaulting Series EA Partner under this
Section 5.6(e) multiplied by three) by (y) the sum of the Series EA Capital Accounts of all Series EA Partners (including
all Capital Contributions made under this Section 5.6(e) multiplied by three) and (B) such Defaulting Series EA Partner to equal
the amount of (x) such Defaulting Series EA Partner’s Series EA Percentage Interest immediately prior to the occurrence of
such default less (y) the aggregate increases to the Series EA Percentage Interests of Non-Defaulting Series EA Partners pursuant
to clause (A). Notwithstanding the foregoing, the Defaulting Series EA Partner will have the right to re-acquire the interest in
question from any advancing Non-Defaulting Series EA Partner within 30 days following the date on which such Series EA Percentage
Interest adjustment is made by paying the entire amount advanced by such Non-Defaulting Series EA Partner in return for such adjustment,
plus interest thereon at a rate equal to the lesser of (A) the maximum, lawful interest rate, compounded monthly, that is
then-currently permitted under applicable law, (B) 12% per annum or (C) in the case of an advance from EECI or its Affiliates
to Enbridge Partners or its Subsidiaries, the rate that would be charged Enbridge Partners by unrelated lenders on a comparable
loan, whereupon the Series EA Percentage Interests of each Series EA Partner shall be adjusted to equal the Percentage Interest
such Series EA Partner would have had in the absence of a default by such Defaulting Series EA Partner.

 

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

 

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

 

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

 

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

 

    	61

     

    

 

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

 

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

 

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

 

Section
5.7           Initial Series ME Capital Contributions.

 

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

 

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

 

    	62

     

    

 

(c)          On June 28,
2013, EECI and Enbridge Partners entered into the Option Purchase Agreement whereby Enbridge Partners sold to EECI a portion of
the Series ME Limited Partner Interests owned by Enbridge Partners representing, in the aggregate, 15% of the total outstanding
Series ME Limited Partner Interests in accordance with Section 4.12 of the Fifth A&R Agreement. The Percentage Interests of
each Series ME General Partner and Series ME Limited Partner as of the date of this Agreement are as set forth on Exhibit A.

 

Section
5.8           Additional Series ME Capital Contributions.

 

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

 

(ii) Commencing with
and including the date on which the Series ME Capital Contribution Notice is delivered to the Series ME Partners in August 2015
and continuing through the earlier of (A) the first date after the date on which the Series ME Distribution is paid with respect
to the Quarter ending March 31, 2016 on which Enbridge Partners has made Additional Series ME Capital Contributions pursuant to
this Section 5.8(a)(ii) in excess of its Pro Rata portion in an amount equal to the Series ME Abatement Amount determined as of
the date immediately following the date on which the Series ME Distribution for the Quarter ending
March 31, 2016 is paid and (B) December 31, 2016, with respect to each Series ME Capital Contribution Notice, Enbridge Partners
shall contribute its Pro Rata portion of any Additional Series ME Capital Contribution plus the Series ME Contribution Offset Amount,
and EECI shall contribute an amount equal to its Pro Rata portion of such Additional Series ME Capital Contribution less the Series
ME Contribution Offset Amount; provided, that (1) Enbridge Partners’ contribution with respect to any such Series
ME Capital Contribution Notice shall in no event exceed 100.0% of the Additional Series ME Capital Contributions specified in such
Series ME Capital Contribution Notice and (2) EECI’s contribution with respect to any such Series ME Capital Contribution
Notice shall in no event be less than zero.

 

    	63

     

    

 

(b)          On the 12th
day of each month beginning prior to the Mainline Expansion Final In-Service Date, the Managing General Partner of the Series ME
shall deliver a Series ME Capital Contribution Notice to each of the Series ME Partners setting forth (i) the estimated
cash construction costs related to the Mainline Expansion Project for such month, adjusted for the difference between (A) the
actual construction costs related to the Mainline Expansion Project for the immediately preceding month and (B) the estimated
construction costs set forth in the Series ME Capital Contribution Notice for the immediately preceding month (the “Series
ME Monthly Capital Requirement”), (ii) the amount of the required Additional Series ME Capital Contribution
to be made by such Series ME Partner, which, except as provided in Section 5.8(a)(ii), shall be an amount equal to such Series ME
Partner’s Pro Rata portion of the Series ME Monthly Capital Requirement, (iii) that such Additional Series ME Capital
Contribution is due on the 15th day of such month and (iv) the Person or the account to which such Additional Series ME
Capital Contribution is to be made.

 

(c)          From time to
time following the Mainline Expansion Final In-Service Date, the Managing General Partner of the Series ME may deliver to
the Series ME Partners a Series ME Capital Contribution Notice related to amounts that the Managing General Partner of
the Series ME determines are necessary to fund the Series ME’s operations and establish reasonable reserves in
respect of the Series ME’s expenses. Such notice shall set forth (i) the manner in which, and the expected date
on which, such Additional Series ME Capital Contribution is to be applied, (ii) the amount of the required Additional
Series ME Capital Contribution to be made by such Series ME Partner, which, except as provided in Section 5.8(a)(ii),
shall be an amount equal to such Series ME Partner’s Pro Rata portion of the total amount of such Additional Series ME
Capital Contribution, (iii) the date on which such Additional Series ME Capital Contribution is due, which shall not
be less than 10 Business Days from the date such notice is delivered and (iv) the Person or the account to which such Additional
Series ME Capital Contribution is to be made.

 

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

 

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

 

    	64

     

    

 

(i)          To the extent
that one or more Non-Defaulting Series ME Partners do not elect to have an advance made pursuant to this Section 5.8(e) treated
as a loan to the Defaulting Series ME Partner, or affirmatively elects to have such advance treated as a Capital Contribution,
the Managing General Partner of the Series ME will automatically adjust the Series ME Percentage Interest of (A) each such
Non-Defaulting Series ME Partner to equal the percentage obtained by dividing (x) the Series ME Capital Account of each such
Non-Defaulting Series ME Partner (including any Capital Contribution made by such Non-Defaulting Series ME Partner under this Section
5.8(e) multiplied by three) by (y) the sum of the Series ME Capital Accounts of all Series ME Partners (including all Capital
Contributions made under this Section 5.8(e) multiplied by three) and (B) such Defaulting Series ME Partner to equal the amount
of (x) such Defaulting Series ME Partner’s Series ME Percentage Interest immediately prior to the occurrence of such default
less (y) the aggregate increases to the Series ME Percentage Interests of Non-Defaulting Series ME Partners pursuant to clause
(A). Notwithstanding the foregoing, the Defaulting Series ME Partner will have the right to re-acquire the interest in question
from any advancing Non-Defaulting Series ME Partner within 30 days following the date on which such Series ME Percentage Interest
adjustment is made by paying the entire amount advanced by such Non-Defaulting Series ME Partner in return for such adjustment,
plus interest thereon at a rate equal to the lesser of (A) the maximum, lawful interest rate, compounded monthly, that is
then-currently permitted under applicable law, (B) 12% per annum or (C) in the case of an advance from EECI or its Affiliates
to Enbridge Partners or its Subsidiaries, the rate that would be charged Enbridge Partners by unrelated lenders on a comparable
loan, whereupon the Series ME Percentage Interests of each Series ME Partner shall be adjusted to equal the Percentage Interest
such Series ME Partner would have had in the absence of a default by such Defaulting Series ME Partner.

 

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

 

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

 

    	65

     

    

 

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

 

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

 

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

 

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

Section
5.9           Initial Series L3R Capital Contributions.

 

(a)          On the Series
L3R Closing Date, each of the Series L3R Partners made its respective Capital Contribution (each, an “Initial Series L3R
Capital Contribution”) to the Series L3R in the amounts set forth opposite its name on Exhibit A in
return for the Series L3R Percentage Interest and type of Series L3R Partnership Interest set forth opposite its name
on Exhibit A, and each such Series L3R Partner was admitted as a Partner of the Series L3R in the capacity
set forth opposite its name on Exhibit A.

 

(b)          On the Series
L3R Closing Date, the Managing General Partner of Series L3R applied the proceeds of the Initial Series L3R Capital Contributions
to (i) repay the Intercompany Preliminary L3R Construction Cost Payable and (ii) pay to Enbridge Partners the L3R Additional True-Up
Amount.

 

Section
5.10          Additional Series L3R Capital Contributions.

 

(a)          Each Series
L3R Partner hereby agrees to make additional Capital Contributions to the Series L3R (the “Additional Series L3R Capital
Contributions”) in proportion to such Series L3R Partner’s Series L3R Percentage Interest at such times and in
such amounts as the Managing General Partner of the Series L3R shall specify in a notice delivered to the Series L3R Partners pursuant
to Section 5.10(b) or Section 5.10(c) (“Series L3R Capital Contribution Notice”); provided that in no event
shall any Series L3R Partner be required to make, in the aggregate, Capital Contributions in excess of such Series L3R Partner’s
respective Maximum Commitment with respect to Series L3R set forth on Exhibit A. All Additional Series L3R Capital Contributions
shall be contributed to the Series L3R in immediately available U.S. dollars on the date specified in the applicable Series L3R
Capital Contribution Notice. No Series L3R Partner shall be required to make any Additional Series L3R Capital Contribution, or
to otherwise contribute any amount, to the Series L3R unless such Additional Series L3R Capital Contribution is reflected on the
Series L3R Annual Budget for such fiscal year or is otherwise approved by the Managing General Partner of the Series L3R and a
Supermajority Interest of Series L3R Partnership Interests.

 

(b)          On the 12th
day of each month beginning prior to the L3R In-Service Date, the Managing General Partner of the Series L3R shall deliver a Series
L3R Capital Contribution Notice to each of the Series L3R Partners setting forth (i) the estimated cash construction costs related
to the Line 3 Replacement Project for such month, adjusted for the difference between (A) the actual construction costs related
to the Line 3 Replacement Project for the immediately preceding month and (B) the estimated construction costs set forth in the
Series L3R Capital Contribution Notice for the immediately preceding month (the “Series L3R Monthly Capital Requirement”),
(ii) the amount of the required Additional Series L3R Capital Contribution to be made by such Series L3R Partner, which shall be
an amount equal to such Series L3R Partner’s Pro Rata portion of the Series L3R Monthly Capital Requirement, (iii) that such
Additional Series L3R Capital Contribution is due on the 15th day of such month and (iv) the Person or the account to which such
Additional Series L3R Capital Contribution is to be made.

 

    	67

     

    

 

(c)          From time to
time following the L3R In-Service Date, the Managing General Partner of the Series L3R may deliver to the Series L3R Partners a
Series L3R Capital Contribution Notice related to amounts that the Managing General Partner of the Series L3R determines are necessary
to fund the Series L3R’s operations and establish reasonable reserves in respect of the Series L3R’s expenses. Such
notice shall set forth (i) the manner in which, and the expected date on which, such Additional Series L3R Capital Contribution
is to be applied, (ii) the amount of the required Additional Series L3R Capital Contribution to be made by such Series L3R Partner,
which shall be an amount equal to such Series L3R Partner’s Pro Rata portion of the total amount of such Additional Series
L3R Capital Contribution, (iii) the date on which such Additional Series L3R 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
L3R Capital Contribution is to be made.

 

(d)          Each Series
L3R Partner agrees that payment of its required Additional Series L3R Capital Contributions under this Agreement is an obligation
of such Series L3R Partner, that any default by any Series L3R Partner would cause injury to the Series L3R and to the other Series
L3R Partners and that the amount of damages caused by any such default would be difficult to calculate.

 

(e)          If a Series
L3R Partner fails to fund all or any portion of its required Additional Series L3R Capital Contribution set forth in a Series L3R
Capital Contribution Notice and fails to cure such default within five Business Days after the due date set forth in such Series
L3R Capital Contribution Notice (the “Default Series L3R Capital Contribution”), the Series L3R Partner failing
to make such contribution (the “Defaulting Series L3R Partner”) will be in default. Upon the occurrence of any
such default, the Managing General Partner of Series L3R shall promptly notify the Defaulting Series L3R Partner and the other
Series L3R Partners not in default (each a “Non-Defaulting Series L3R Partner”) of the occurrence of such default.
As long as a Default Series L3R Capital Contribution remains unpaid or arrangements for the payment thereof have not been agreed
to by the Series L3R Partners, any Non-Defaulting Series L3R Partner may advance to the Series L3R the entire amount of the Defaulting
Series L3R Partner’s Capital Contribution that has not been contributed, with each Non-Defaulting Series L3R Partner electing
to participate in such advance making its share of such advance in proportion to its Series L3R Percentage Interest (without taking
into account the Series L3R Percentage Interest of the Defaulting Series L3R Partner). Each Non-Defaulting Series L3R Partner who
makes such an advance on behalf of a Defaulting Series L3R Partner will have the right to elect the extent to which such advance
will (x) constitute a loan to the Defaulting Series L3R Partner and/or (y) be treated as a Capital Contribution by such Non-Defaulting
Series L3R Partner and result in an immediate adjustment of the Series L3R Percentage Interests of the Defaulting Series L3R Partner
and the Non-Defaulting Series L3R Partner making such election in accordance with Section 5.10(e)(i); provided, however, that if
the advancing Non-Defaulting Series L3R Partner does not notify the Managing General Partner of the Series L3R of its election
to have all, or any portion of, such advance treated as a loan to the Defaulting Series L3R 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 L3R Percentage Interests.

 

    	68

     

    

 

(i)          To
the extent that one or more Non-Defaulting Series L3R Partners do not elect to have an advance made pursuant to this Section 5.10(e)
treated as a loan to the Defaulting Series L3R Partner, or affirmatively elects to have such advance treated as a Capital Contribution,
the Managing General Partner of the Series L3R will automatically adjust the Series L3R Percentage Interest of (A) each such Non-Defaulting
Series L3R Partner to equal the percentage obtained by dividing (x) the Series L3R Capital Account of each such Non-Defaulting
Series L3R Partner (including any Capital Contribution made by such Non-Defaulting Series L3R Partner under this Section 5.10(e)
multiplied by three) by (y) the sum of the Series L3R Capital Accounts of all Series L3R Partners (including all Capital Contributions
made under this Section 5.10(e) multiplied by three) and (B) such Defaulting Series L3R Partner to equal the amount of (x) such
Defaulting Series L3R Partner’s Series L3R Percentage Interest immediately prior to the occurrence of such default less (y)
the aggregate increases to the Series L3R Percentage Interests of Non-Defaulting Series L3R Partners pursuant to clause (A). Notwithstanding
the foregoing, the Defaulting Series L3R Partner will have the right to re-acquire the interest in question from any advancing
Non-Defaulting Series L3R Partner within 30 days following the date on which such Series L3R Percentage Interest adjustment is
made by paying the entire amount advanced by such Non-Defaulting Series L3R 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
L3R Percentage Interests of each Series L3R Partner shall be adjusted to equal the Percentage Interest such Series L3R Partner
would have had in the absence of a default by such Defaulting Series L3R Partner.

 

(ii)          To
the extent one or more Non-Defaulting Series L3R Partners (each, a “Lending Series L3R Partner”) elects to have
an advance made pursuant to this Section 5.10(e) constitute a loan to the Defaulting Series L3R Partner, such advance will have
the following results (except to the extent otherwise agreed by the Lending Series L3R Partner and the Defaulting Series L3R Partner,
each in their sole discretion):

 

(A)          the
sum advanced will constitute a loan from the Lending Series L3R Partner to the Defaulting Series L3R Partner and an Additional
Series L3R Capital Contribution of that sum to the Series L3R by the Defaulting Series L3R Partner pursuant to the applicable provisions
of this Agreement;

 

(B)          the
principal balance of the loan together with all accrued unpaid interest thereon and all costs and expenses associated therewith
(collectively, the “Defaulting Series L3R 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 L3R Partner Obligation is made
by the Lending Series L3R Partner to the Defaulting Series L3R Partner; provided, however, that the Defaulting Series L3R Partner
may prepay the Defaulting Series L3R 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;

 

    	69

     

    

 

(D)          the
Lending Series L3R 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 L3R Partner may deem appropriate to obtain payment
from the Defaulting Series L3R Partner of the Defaulting Series L3R Partner Obligation; and

 

(E)          initially,
a loan by a Lending Series L3R Partner to a Defaulting Series L3R Partner as contemplated by this Section 5.10(e)(ii) will not
be considered a Capital Contribution by such Lending Series L3R Partner and will not increase the Capital Account balance of such
Lending Series L3R 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 L3R Partner, at any time thereafter by giving written notice to the
Managing General Partner of the Series L3R and the Defaulting Series L3R Partner, may elect to have an amount equal to the unpaid
principal and interest balance of such loan transferred from such Defaulting Series L3R Partner’s Capital Account to such
Lending Series L3R Partner’s Capital Account and increase such Lending Series L3R Partner’s Capital Account with a
corresponding decrease in such Defaulting Series L3R Partner’s Capital Account. Upon such transfer, the loan will be treated
as a Capital Contribution and the Series L3R Percentage Interest for (A) such Lending Series L3R Partner will be automatically
adjusted to equal the percentage obtained by dividing (x) the Capital Account of such Lending Series
L3R Partner (including any Capital Contribution made by such Lending Series L3R Partner under this Section 5.10(e)(ii)(E)
on behalf of the Defaulting Series L3R Partner multiplied by three) by (y) the sum of the Series L3R Capital Accounts of all Series
L3R Partners (including all Capital Contributions made under this Section 5.10(e)(ii)(E) on behalf of the Defaulting Series L3R
Partner multiplied by three) and (B) such Defaulting Series L3R Partner will be automatically adjusted to equal the amount of (x)
such Defaulting Series L3R Partner’s Series L3R Percentage Interest immediately prior to such election by the Lending Series
L3R Partner less (y) the increase to the Series L3R Percentage Interest of Lending Series L3R Partner pursuant to clause (A).

 

(f)          Notwithstanding
the rights of Non-Defaulting Series L3R Partners described in Section 5.10(e), the Managing General Partner of the Series L3R,
by a vote of a Supermajority Interest of Series L3R Partnership Interests (without taking into account the Series L3R Partnership
Interests of the Defaulting Series L3R Partner), will have the right to exercise any rights
and remedies available at law or in equity.

Section
5.11          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
5.12          Capital Accounts.

 

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

 

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

 

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

 

(d)          Whenever the
fair market value of property of a Series is required to be determined pursuant to this Section 5.12, the Managing General
Partner of such Series shall establish the fair market value in a notice to the Partners of such Series.

 

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

ALLOCATIONS AND DISTRIBUTIONS

 

Section
6.1           Allocations for Capital Account Purposes.

 

(a)          Allocations.
For purposes of maintaining the Series Capital Accounts pursuant to Section 5.12 and in determining the rights of the Partners
among themselves with respect to each Series, after making all of the allocations under Sections 6.1(b) and 6.1(c), Profits and
Losses and items thereof with respect to a Series shall be allocated among the Partners of such Series in each taxable year (or
portion thereof) as provided herein below.

 

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

 

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

 

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

 

(iv)          Series
L3R. Each item of income, gain, loss, deduction and credit attributable to Series L3R Assets and Series L3R Liabilities shall be
allocated to the Series L3R Partners in accordance with their respective Series L3R Percentage Interests.

 

(v)          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.

 

(vi)          Notwithstanding
Sections 6.1(a)(i), 6.1(a)(ii), 6.1(a)(iii), 6.1(a)(iv) and 6.1(a)(v) 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.

 

    	72

     

    

 

(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):

 

    	73

     

    

 

(A)          in the
event that the Series LH Partners become obligated to make payments to the Series AC Partners, Series EA Partners, Series
ME Partners or Series L3R Partners pursuant to Section 6.2(c), Section 6.3(c), Section 6.4(c) or Section 6.5(c), items of
Partnership gross income and gain shall be allocated to the Series LH Partners in accordance with their respective Series LH
Percentage Interests until the aggregate amounts of items allocated to the Series LH Partners pursuant to this Section 6.1(b)(iv)
for such taxable year and all prior taxable years equals the cumulative amount of payments made by the Series LH Partners
to the Series AC Partners, Series EA Partners, Series ME Partners or Series L3R Partners, as applicable, pursuant to Section 6.2(c),
Section 6.3(c), Section 6.4(c) or Section 6.5(c) for such taxable year and all prior taxable years;

 

(B)          in the
event that the Series AC Partners become obligated to make payments to the Series LH Partners pursuant to Section 6.6(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 6.6(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 6.6(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 6.6(d) for such taxable year and all prior taxable years;

 

(D)          in the
event that the Series ME Partners become obligated to make payments to the Series LH Partners pursuant to Section 6.6(e), items
of Partnership gross income and gain shall be allocated to the Series ME Partners in accordance with their respective Series ME
Percentage Interests until the aggregate amounts of items allocated to the Series ME Partners pursuant to this Section 6.1(b)(iv)
for such taxable year and all prior taxable years equals the cumulative amount of payments made by the Series ME Partners to the
Series LH Partners pursuant to Section 6.6(e) for such taxable year and all prior taxable years; and

 

(E)          in the
event that the Series L3R Partners become obligated to make payments to the Series LH Partners pursuant to Section 6.6(f), items
of Partnership gross income and gain shall be allocated to the Series L3R Partners in accordance with their respective Series L3R
Percentage Interests until the aggregate amounts of items allocated to the Series L3R 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 L3R Partners to the
Series LH Partners pursuant to Section 6.6(f) for such taxable year and all prior taxable years.

 

    	74

     

    

 

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

 

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

 

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

 

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

 

(c)          Curative
Allocation. The Regulatory Allocations are intended to comply with certain requirements of the Treasury Regulations. It is
the intent of the Partners that, to the extent possible, all Regulatory Allocations attributable to a Series shall be offset either
with other Regulatory Allocations attributable to such Series, or with special allocations of other items of income, gain, loss
or deduction attributable to such Series pursuant to this Section 6.1(c). Therefore, notwithstanding any other provision of
this Article VI (other than the Regulatory Allocations), but subject to the Code and the Treasury Regulations, the Managing
General Partner of the applicable Series shall make such offsetting special allocations of income, gain, loss or deduction in whatever
manner it determines appropriate so that, after such offsetting allocations are made, each Partner’s applicable Series Capital
Account balance is, to the extent possible, equal to the balance such Partner would have had if the Regulatory Allocations were
not part of this Agreement. In exercising its discretion under this Section 6.1(c), the Managing General Partner of the applicable
Series shall take into account future Regulatory Allocations that, although not yet made, are likely to offset other Regulatory
Allocations previously made.

 

    	75

     

    

 

(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 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

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 7.15, 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 7.15 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 7.15(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 7.15.

 

(c)          The indemnification
provided by this Section 7.15 shall be in addition to any other rights to which an Indemnitee may be entitled under any agreement,
pursuant to any vote of a Majority in Interest of Partnership Interests, in the case of the Series AC and the Series LH, or a Supermajority
Interest of the Partnership Interests, in the case of the Series EA, the Series ME and the Series L3R, 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

against any liability that may be asserted against, or expense that may be incurred by, such Person in connection with such Series’

(f)          An Indemnitee

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 7.15 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 7.15 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 7.15 as in effect immediately prior to such amendment,
modification or repeal with respect to Claims arising from or relating to matters occurring, in whole or in part, prior to such
amendment, modification or repeal, regardless of when such Claims may arise or be asserted.

 

(i)          The provisions
of this Section 7.15 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

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 7.16 shall be made (i) only out of the assets of the Indemnifying Series, it
being agreed that, except as provided in Section 11.7, no Partner shall be personally liable for such indemnification nor shall
any Partner have any obligation to contribute or loan any monies or property to the Indemnifying Series to enable it to effectuate
such indemnification and (ii) only to the extent that the Partners of the Indemnified Series have not received a payment from the
Partners of the Indemnifying Series under Sections 6.2, 6.3, 6.4, 6.5 or 6.6 with respect to a shortfall related to the Liability
that gave rise to the Series Indemnified Damages.

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 7.17 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 7.17 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

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 any Series solely as a result of its status as a General Partner of the Partnership generally.

 

Section

or have the power to sign documents for or otherwise bind the Partnership or any Series. Any action taken by any Affiliate of a
General Partner or any officer, director, employee, manager, member, general partner, agent or trustee of a General Partner or
any of its Affiliates shall not be deemed to be participation in the control of the business of the Partnership or any Series by
a Limited Partner of the Partnership generally or any Series (within the meaning of Section 17-303(a) of the Delaware Act)
and shall not affect, impair or eliminate the limitations on the liability of the Limited Partners under this Agreement.

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

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

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,

accepted accounting practices or principles. In the absence of bad faith by such Managing General Partner, the resolution, action
or terms so made, taken or provided by such Managing General Partner shall be permitted and deemed approved by all the Partners
and shall not constitute a breach of this Agreement or any other agreement contemplated herein or of any duty, including any fiduciary
duty, or obligation of such Managing General Partner at law or in equity or otherwise, and it shall be presumed in making its decision

generally is designated as the Tax Matters Partner (as defined in the Code) and is authorized and required to represent the Partnership
in connection with all examinations of the Partnership’s affairs by tax authorities, including resulting administrative and
judicial proceedings, and to expend funds for professional services and costs associated therewith.

 

(i)          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.

 

(ii)          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

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.

 

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

 

(iv)          No

terms within 90 days from the date of the settlement.

 

    	97

     

    

 

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

 

(b)          For all tax
years beginning after December 31, 2017, pursuant to Section 6221 et. seq., Subchapter C of Chapter 63 of Subtitle F of the Internal
Revenue Code, the Managing General Partner of the Partnership generally is designated as the “partnership representative”
(such Partner, the “Partnership Representative”) of the Partnership for purposes of the Code. Subject to the

authorized and required, respectively, by the Code for the “partnership representative.”

 

Section

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, Section 6.4 Section 6.5
or Section 6.6, as applicable, in the amount of such withholding from such Partner.

 

Section
9.6           Tax Reimbursement.

 

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

Section
9.7           Tax Partnership.

 

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

Section
10.1          Fundamental Change.

 

(a)          If, at any time,
(i) EECI is removed as the general partner of Enbridge Partners pursuant to Section 13.2 (or equivalent provision) of
the Eighth Amended and Restated Agreement of Limited Partnership of Enbridge Partners, as amended, or (ii) Enbridge Partners
shall cease to directly or indirectly Control the Partnership generally and each Series (each, a “Fundamental Change”),
then (x) the Managing General Partner of Series EA shall, without any further action on its part, be deemed to have automatically
and irrevocably delegated to EECI EA Sub (or its designee), (y) the Managing General Partner of Series ME shall, without any further
action on its part, be deemed to have automatically and irrevocably delegated to EECI ME Sub (or its designee) and (z) the Managing
General Partner of Series L3R shall, without any further action on its part, be deemed to have automatically and irrevocably delegated
to EECI L3R Sub (or its designee) in each case, to the fullest extent permitted under this Agreement and Delaware law, all of such
Managing General Partner’s power and authority to manage and control the business and affairs of the applicable Series (such
delegation being referred to herein as the “Maximum Permitted Delegation”), subject to termination only in the
sole discretion of EECI EA Sub, EECI ME Sub or EECI L3R 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 EA Sub, EECI ME Sub or EECI L3R 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 EA, the Series ME and the
Series L3R by providing five Business Days’ prior written notice of such election to the Managing General Partner of the
Partnership generally at any time (such election, the “Control Option”). Upon exercise of the Control Option:

 

(i)          the
Limited Partner Interest of EECI EA Sub in the Series EA shall automatically convert into a General Partner Interest in the Series
EA, the Limited Partner Interest of EECI ME Sub in the Series ME shall automatically convert into a General Partner Interest in
the Series ME and the Limited Partner Interest of EECI L3R Sub in the Series L3R shall automatically convert into a General Partner
Interest in the Series L3R;

 

(ii)         EECI
EA Sub shall automatically become the Managing General Partner of the Series EA, EECI ME Sub shall automatically become the Managing
General Partner of the Series ME and EECI L3R Sub shall automatically become the Managing General Partner of the Series L3R in

and

 

(iii)        all
rights, powers and obligations of the existing Managing General Partner of the Series EA, Series ME and the Series L3R (in its
capacity as such) shall immediately terminate.

 

The exercise of the Control Option pursuant
to this Section 10.1(b) shall not affect (A) the status of any Managing General Partner of the Partnership generally
or any Series (other than the Series EA, Series ME or the Series L3R) or (B) the Percentage Interest of the Series EA Partners,
the Series ME Partners or the Series L3R.

(c)          In connection
with the exercise of the Control Option pursuant to this Section 10.1, each of the Partners agrees to cooperate with respect
to such matters and to execute such further assignments, releases, assumptions, amendments of this Agreement and the Certificate
of Limited Partnership, notifications and other documents as may be reasonably requested by EECI, EECI EA Sub, EECI ME Sub, EECI
L3R Sub or the Managing General Partner of the Series EA, Series ME or Series L3R, as applicable, for the purpose of giving effect
to, or evidencing or giving notice of, the transactions contemplated by such provisions and the otherwise continued operations
of the Partnership.

 

Section
10.2          Alberta Clipper Surcharge Expiration.

 

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

 

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

 

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

 

    	102

     

    

 

(d)          If the Alberta
Clipper Revised Tariff Structure does not set forth an objectively determinable definition of (i) the revenue that the Partnership
is entitled to collect in tolls and other charges in respect of the Series AC Assets and (ii) the expenses that the Partnership
is entitled to allocate in respect of the Series AC Assets, and EECI and Lakehead GP are unable to agree on an allocation
arrangement pursuant to Section 10.2(c), such allocation arrangement shall be determined through binding arbitration using
three arbitrators, in accordance with the Commercial Arbitration Rules of the American Arbitration Association, as supplemented
to the extent necessary to determine any procedural appeal questions by the Federal Arbitration Act (Title 9 of the United States
Code). If there is any inconsistency between this Section 10.2(d) and the Commercial Arbitration Rules or the Federal Arbitration
Act, the terms of this Section 10.2(d) will control the rights and obligations of the parties. Arbitration shall be initiated
180 days prior to the expiration of the Alberta Clipper Surcharge Term. Each of EECI and Lakehead GP shall appoint an arbitrator
at least 150 days prior to the expiration of the Alberta Clipper Surcharge Term. If either party fails for any reason to name an
arbitrator within such period, the other party shall petition to the American Arbitration Association for appointment of an arbitrator
for such party’s account. The two arbitrators so chosen shall select a third arbitrator within 15 days after the second arbitrator
has been appointed. Each of EECI and Lakehead GP will pay the compensation and expenses of the arbitrator named by or for it. The
costs of petitioning for the appointment of an arbitrator, if any, shall be paid by the party that has failed to appoint an arbitrator
in the requisite period. Each of EECI and Lakehead GP will each pay one-half of the compensation and expenses of the third arbitrator.
All arbitrators must (a) be neutral Persons who have never been officers, directors or employees of Enbridge Partners, EECI
or any of their Affiliates and (b) have not less than seven years experience in the energy industry. The hearing will be conducted
in Houston, Texas and commence within 30 days after the selection of the third arbitrator. Within five days after the selection
of the third arbitrator, EECI and Lakehead GP shall exchange in writing, signed by the respective parties, their respective proposed
allocation arrangements. At the conclusion of the hearing, the arbitrators shall choose either the allocation arrangement of EECI
or the allocation arrangement of Lakehead GP, and shall have no power or authority whatsoever to reach any other result. In making
their choice, the arbitrators shall choose the allocation arrangement that in their judgment most equitably allocates the total
Lakehead System revenues in a manner that best represents the relative economic value of each Series as of the expiration of the
Alberta Clipper Surcharge Term. EECI, Lakehead GP and the arbitrators shall proceed diligently and in good faith in order that
the determination may be made as promptly as possible. Except as provided in the Federal Arbitration Act, the decision of the arbitrators
will be binding on and non-appealable by the parties.

 

Section
10.3          Eastern Access Surcharge Expiration.

 

(a)          Upon the expiration

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).

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

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

Expansion Revised Tariff Structure sets forth an objectively determinable definition of (i) the revenue that the Partnership
is entitled to collect in tolls and other charges in respect of the Series ME Assets and (ii) the expenses that the Partnership
is entitled to allocate in respect of the Series ME Assets, then the Series ME Revenue Entitlement and Series ME

Expansion Revised Tariff Structure does not set forth an objectively determinable definition of (i) the revenue that the Partnership

Sheet so affected. Such allocation arrangement will be based on the relative invested capital of each Series as of the expiration

with such arrangement. If EECI ME Sub and Lakehead GP are unable to agree on such allocation arrangement at least 180 days prior

(e)          Notwithstanding
the provisions of this Section 10.4, following the end of the Mainline Expansion Surcharge Term, EECI ME Sub and Lakehead GP may,
by mutual agreement, elect to remove the Mainline Expansion 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 ME Revenue Entitlement shall be determined by reference to the applicable
toll principles established by applicable regulation or by contract for standalone service.

 

Section
10.5          L3R Surcharge Expiration.

 

(a)          Upon the expiration
or earlier termination of the L3R Support Letters, the L3R Support Letters shall be replaced with a revised tariff structure in
accordance with terms to be negotiated with CAPP at the time of such expiration or termination (the “L3R Revised
Tariff Structure”).

 

(b)          If the L3R 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 L3R Assets and (ii) the expenses that the Partnership is
entitled to allocate in respect of the Series L3R Assets, then the Series L3R Revenue Entitlement and Series L3R
Expenses shall be calculated in accordance with the L3R Revised Tariff Structure.

 

    	106

     

    

 

(c)          If the L3R 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 L3R Assets and (ii) the expenses that the Partnership
is entitled to allocate in respect of the Series L3R Assets, then EECI L3R 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 L3R Support Letters.
Such allocation arrangement will be based on the relative invested capital of each Series as of the expiration or earlier termination
of the L3R Support Letters. If EECI L3R Sub and Lakehead GP are able to agree on such allocation arrangement, then the Series L3R
Revenue Entitlement and Series L3R Expenses will be calculated in accordance with such arrangement. If EECI L3R 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 L3R
Support Letters, then the matter will be submitted to arbitration pursuant to Section 10.5(d).

 

(d)          If the L3R 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 L3R Assets and (ii) the expenses that the Partnership
is entitled to allocate in respect of the Series L3R Assets, and EECI L3R Sub and Lakehead GP are unable to agree on an allocation
arrangement pursuant to Section 10.5(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 10.5(d) and the Commercial Arbitration Rules or the Federal Arbitration
Act, the terms of this Section 10.5(d) will control the rights and obligations of the parties. Arbitration shall be initiated
180 days prior to the expiration of the L3R Support Letters. Each of EECI L3R Sub and Lakehead GP shall appoint an arbitrator at
least 150 days prior to the expiration of the L3R Support Letters. 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 L3R 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 L3R 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 L3R 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 L3R 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 L3R Support Letters. EECI L3R 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 10.5, following the end of the L3R Surcharge Term, EECI L3R Sub and Lakehead GP may, by mutual agreement,
elect to remove the Line 3 Replacement 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 L3R Revenue Entitlement shall be determined by reference to the applicable toll principles established
by applicable regulation or by contract for standalone service.

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

 

(i)          subject
to Section 7.4(q), Section 7.5(q) and Section 7.6(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

(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, Series ME and
Series L3R, 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.

 

    	108

     

    

 

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

 

Section
11.2          Termination of a Series.

 

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

 

(i)          the
dissolution of the Partnership;

 

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

 

(iii)        subject
to Section 7.4(q), Section 7.5(q) and Section 7.6(q), the approval of each General Partner of such Series and a Majority in Interest
of the Partnership Interests of such Series, in the case of the Series AC and Series LH, or a Supermajority Interest of the Partnership
Interests of such Series, in the case of Series EA, Series ME and Series L3R; 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, Series ME and Series L3R, agree in writing or vote to continue the business of
the Series and to the appointment, effective as of the date of such event, if required, of one or more additional general partners
of the Series.

 

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

 

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

 

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

 

    	109

     

    

 

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

 

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

 

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

 

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

 

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

 

    	110

     

    

 

Section
11.4          Cancellation of Certificate of Limited Partnership.

 

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

 

Section
11.5          Return of Capital Contributions.

 

(a)          Except as otherwise
provided by applicable laws, upon termination of a Series, each Partner of such Series shall look solely to the assets of such
Series for the return of its Capital Contributions made to such Series, and if the assets of such Series remaining after satisfaction
(whether by payment or reasonable provision for payment) of the Liabilities of such Series are insufficient to return such Capital
Contributions, such Partner shall have no recourse against any other Series, the Partnership or any Partner, except as otherwise
provided by law or by Section 6.2(c), 6.3(c), 6.4(c), 6.5(c), 6.6(c), 6.6(d), 6.6(e) or 6.6(f).

 

(b)          Except as provided
in Section 6.2(c), 6.3(c), 6.4(c), 6.5(c), 6.6(c), 6.6(d), 6.6(e) or 6.6(f) or 11.7, no General Partner shall be personally
liable for, and shall have no obligation to contribute or loan any monies or property to the Partnership or any Series to enable
it to effectuate, the return of the Capital Contributions of the Limited Partners, or any portion thereof, it being expressly understood
that any such return shall be made solely from Series assets.

 

Section
11.6          Waiver of Partition.

 

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

 

Section
11.7          Capital Account Restoration.

 

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

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

a Supermajority Interest of the Partnership Interests of the Series EA, Series ME and Series L3R.

 

Section

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

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

Section
12.7          Quorum.

any meeting of Partners of such Series. In the absence of a quorum at any such meeting, Partners of such Series holding a Majority

However, if the adjournment is for more than 60 days, a notice of the adjourned meeting shall be given to each Partner of such
Series of record entitled to vote at such meeting. At such adjourned meeting at which a quorum shall be present or represented,
any business may be transacted that might have been transacted at the meeting as originally noticed. The Partners of such Series
present at a duly organized meeting may continue to transact business until adjournment, notwithstanding the withdrawal during
such meeting of Partners of such Series whose absence would cause less than a quorum to be present. If a quorum is present, the
affirmative vote of Partners of such Series holding a Majority in Interest of the Partnership Interests of such Series, in the
case of the Series AC and Series LH, or a Supermajority Interest of the Partnership Interests of such Series, in the case of Series

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.

(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

Any such amendment or adoption made pursuant to this Section 12.11 shall be effective at the effective time or date of the
merger or consolidation.

 

(c)          The Managing
General Partner of the Partnership generally shall have the authority to convert the Partnership to a Delaware statutory trust
if, on the advice of counsel, such conversion (i) is necessary and advisable for Wisconsin GP to have or retain condemnation
authority under Wisc. Stat. § 32.01, et seq. and (ii) would not result in a default under any Indebtedness of
the Partnership or Enbridge Partners existing at such time; provided that (A) the trust is structured as a series trust

extent desired by such Series, priority of use shall be given for the Series AC, the Series EA, the Series ME, the Series L3R or
the Series LH to use such Shared Asset in the following order:

 

		(i)	first, to the Series AC, the Series EA, the Series ME, the Series L3R or the Series LH, to the
extent necessary to address any emergency;

 

		(ii)	second, prior to the Eastern Access Final In-Service Date, Mainline Expansion Final In-Service
Date and L3R In-Service Date, as applicable, to the Series EA, Series ME and Series L3R equally, to the extent necessary in connection
with the construction of the Eastern Access Project, the Mainline Expansion Project and the Line 3 Replacement Project; provided
that the Series EA’s, Series ME’s and Series L3R’s use of the Shared Assets pursuant to this clause (ii) shall
not result in interruptions that could materially and adversely affect the business operations of the Series AC, Series EA, Series
ME, the Series L3R or Series LH without the consent of the affected Series’ Shared Asset Manager; and

 

		(iii)	third, in the proportions required by the Series AC, the Series EA, the Series ME, the Series L3R
and the Series LH to conduct their respective operations, provided that in the event of a conflict limiting the ability
of one or more Series to make use of a particular Shared Asset to the extent desired by such Series, the Managing General Partner
of the Partnership generally shall determine priority of use for each Series based on the needs of each Series in respect of such
Shared Asset.

 

(e)          Standard of
Care. Each Series shall act with respect to the Shared Assets (i) in a professional manner and in accordance with generally
accepted industry standards, (ii) in accordance with the Partnership’s policies, procedures and requirements, as determined
by the Managing General Partner of the Partnership generally, and (iii) in accordance with applicable law in all material respects.
Each Series shall use commercially reasonable efforts to do or cause to be done all such things as shall be necessary and proper
with respect to the Shared Assets to ensure that the rights of the other Series in respect of the Shared Assets shall be preserved
for the benefit of such Series.

 

    	F-4

     

    

 

4.2          Management
of Shared Assets.

 

(a)          Managers. Each
Series hereby appoints the Managing General Partner of such Series (each a “Shared Asset Manager”) to serve
as the primary point of contact for communications between the Series relating to the day-to-day operations of the Shared Assets,
to have overall responsibility for managing and coordinating the performance of the appointing Series’ obligations under
this Exhibit F, and to be authorized to act for and on behalf of the appointing Series concerning all matters relating to
this Exhibit F.

 

(b)          Decisions.

 

		(i)	All decisions in respect of the Shared Assets shall require the unanimous decision of the Shared
Asset Managers of each Series unless otherwise required by the terms of this Agreement. The Shared Asset Managers shall act reasonably,
taking into account the considerations of each Series, in connection with all decisions regarding the Shared Assets.

 

		(ii)	In the event of a conflict between the Shared Asset Managers of any Series, then (1) if one Series
has priority of use pursuant to Section 4.1(d) of this Exhibit F, then such Series shall prevail and (2) other decisions
shall be made by the Shared Asset Manager of the Series that is reasonably likely to bear the greater proportion of the costs relating
to such matter.

 

		(iii)	If the Shared Asset Managers are not the same Person, then notwithstanding the foregoing, the following
actions shall require the prior written consent of a Majority in Interest of each of the Series AC and Series LH and a Supermajority
Interest of the Series EA, Series ME and Series L3R:

 

		(A)	the disposition, transfer, sale, conveyance or exchange of any Shared Asset in excess of $25,000,000,
in each case; or

 

		(B)	material modifications of the Shared Contracts, Shared Real Property Rights or Shared Permits.

 

(c)          Meetings. The
Shared Asset Managers agree to have meetings if called at any time upon five Business Days prior written notice by a Shared Asset
Manager. Each Series shall make available at such meetings their personnel who are familiar with the details of the particular
Shared Assets under review.

 

    	F-5

     

    

 

4.3          Capital Improvements.

 

(a)          A Series (the
“Improvement Series”) may submit from time to time to each other Series written requests to undertake capital
expenditures or capital improvement projects relating to 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 F, 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 to agree to undertake any Capital Improvement Project and may reject any request by the other Series. If the
Series agree to undertake any Capital Improvement Project, the Series shall cooperate in good faith to reach agreement on the allocation
of responsibility for all costs associated with such Capital Improvement Project.

 

(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.

 

4.4          Nature of
Right to Use. The right to use the Shared Assets as provided in this Exhibit F (i) is an integral, non-severable part
of the Agreement, (ii) is an integral part of the Partnership Interests of the Series and the assets of the Series designated under
the Agreement and (iii) shall not be deemed to be an executory contract or agreement that can be rejected or otherwise terminated
in any bankruptcy, receivership or similar proceeding of the Partnership.

 

4.5          Valuation.
In any valuation of the assets of a Series, the value of such assets shall include the continuing right to use the Shared Assets
as provided in this Exhibit F.

5.1          Force
Majeure Event.

 

(a)          Subject to the
following provisions of this Article V, a Series shall not be in default hereunder or responsible for any loss or damage to the
other Series resulting from any delay in performing or failure to perform any obligation of such Series under this Exhibit F
(other than payment obligations) to the extent such failure or delay is caused by a Force Majeure Event.

 

(b)          “Force
Majeure Event” means the following events, conditions and circumstances, except to the extent any of the following is

involved are within the power of the claiming Series to concede; or

 

		(iii)	compliance with any order, action, direction or request of any Governmental Authority or with any
applicable law not brought about by any action or omission on the part of the Series claiming the Force Majeure Event.

 

5.2          Force Majeure
Notice. The Series whose ability to perform is affected by a Force Majeure Event must, as a condition to its right to suspend
its obligations under Section 5.1 of this Exhibit F, (i) be actually prejudiced by such Force Majeure Event and (ii) promptly
give the other Series notice setting forth the particulars of the Force Majeure Event and, to the extent possible, the expected
duration of the Force Majeure Event. Such notice shall also include a description of the steps taken and proposed to be taken to
lessen and cure the Force Majeure Event. The cause of the Force Majeure Event shall so far as commercially reasonable be remedied
with all reasonable dispatch, except that no Series shall be obligated to resolve any labor disputes other than as it shall determine
to be in its best interests.

STRICTLY CONFIDENTIAL

 

NeuroMetrix, Inc.

1000 Winter Street

Waltham, MA 02451

Attn: Thomas Higgins

 

Reference is made to
the engagement agreement (the “Engagement Agreement”), dated June 2, 2016, as amended on November 22, 2016 and
December 19, 2016, by and between NeuroMetrix, Inc. (the “Company”) and Rodman & Renshaw, a unit of H.C.
Wainwright & Co., LLC (“Rodman”), pursuant to which Rodman shall serve as the exclusive agent, advisor or
underwriter of the Company in connection with an Offering (as defined in the Engagement Agreement).

 

The Company and Rodman
hereby agree to amend Section A.2 and A.3 of the Engagement Agreement. As such, Section A.2 is hereby amended and restated in its
entirety to read as follows:

 

Warrant Coverage.
The Company shall issue to Rodman or its designees at each Closing, warrants (the “Rodman Warrants”) to purchase
that number of shares of common stock of the Company equal to 7.5% of the aggregate number of shares of Common Stock issued as
a result of new investments in the Company’s securities made in each Offering (and if the Securities are convertible or include
a “greenshoe” or “additional investment” option component, such number of shares of Common Stock underlying
such Securities or options, with the warrant issuable upon conversion of the Securities or the exercise of the option). If the
Securities included in an Offering are non-convertible, the Rodman Warrants shall be determined by dividing the gross proceeds
raised in such Offering divided by the then market price of the Common Stock. The Rodman Warrants shall have the same terms as
the warrants issued to investors in the applicable Offering, except that such Rodman Warrant shall have an exercise price equal
to 125% of the public offering price per share in the applicable Offering. If no warrants are issued to investors in an Offering,
the Rodman Warrants shall be in a customary form reasonably acceptable to the Company and to Rodman, have a term of 5 years and
an exercise price equal to 125% of the then market price of the Common Stock.

 

As such, Section A.3
is hereby amended and restated in its entirety to read as follows:

 

Expense Allowance.
Out of the proceeds of each Closing (which Closing may consist of one or more closings related to the same Offering), the Company
also agrees to pay Rodman up to $100,000 for its legal fees and expenses, subject to reimbursement by Rodman to the Company if
not used, in accordance with FINRA Rule 5110(f)(2)(C) and (f)(2)(D) (provided, however, that such reimbursement amount
in no way limits or impairs the indemnification and contribution provisions of this Agreement).
