                             CONTRIBUTION AGREEMENT

       THIS CONTRIBUTION AGREEMENT (this "AGREEMENT"), dated as of May 16, 2002,
is entered into by and between Enbridge Energy Company, Inc., a Delaware
corporation ("EECI"), and Enbridge Energy Partners, L.P., a Delaware limited
partnership ("MLP"). Enbridge Midcoast Energy, Inc., a Texas corporation (such
entity, before and after the Conversion Step described in the Recitals below, is
referred to herein as the "COMPANY"), joins in this Agreement for the purposes
set forth in Section 8.1. Capitalized terms used below are defined as set forth
in Section 1.1.

                                 R E C I T A L S

       1. Among other things, the Company owns, directly or indirectly through
the Company Subsidiaries, certain interstate and intrastate pipelines, gathering
systems, gas processing plants and treatment facilities, crude oil pipeline
systems, trucks and railcars for transportation of liquid products and other
assets relating to the treatment, processing, transmission and transportation of
natural gas, crude oil and liquid products in various states, including Texas,
Louisiana, Mississippi, Kansas, Tennessee, Alabama, Oklahoma, New York, Arkansas
and Missouri.

       2.     The Company is a wholly owned subsidiary of EECI.

       3. After the date of this Agreement but prior to the Closing, EECI will
form a single member limited liability company ("HOLDINGS LLC"), and will
contribute 0.001% of the Company Shares to Holdings LLC (the "CONTRIBUTION
STEP").

       4. Immediately following the Contribution Step and prior to the Closing,
the Company will be converted into a Texas limited partnership and its partners
will be (i) EECI, as the owner of a 99.999% limited partner interest, and (ii)
Holdings LLC, as the owner of a 0.001% general partner interest (the "CONVERSION
STEP").

       5. EECI desires to contribute, assign, transfer and convey to MLP, and
MLP desires to accept from EECI, as a capital contribution, after the Conversion
Step, (i) all the membership interests in and to Holdings LLC and (ii) all the
limited partner interests in and to the Company, upon and subject to the terms
of this Agreement.

       NOW, THEREFORE, in consideration of the mutual covenants and agreements
set forth in this Agreement, the parties hereto agree as follows:

                                    ARTICLE 1
                               CERTAIN DEFINITIONS

       1.1 CERTAIN DEFINED TERMS. Unless the context otherwise requires, the
respective terms defined in Appendix A attached hereto and incorporated herein
by this reference shall, when used herein, have the respective meanings therein
specified, with each such definition to be equally applicable both to the
singular and the plural forms of the term so defined.

       1.2 REFERENCES, GENDER, NUMBER. All references in this Agreement to an
"Article," "Section," "subsection," "Exhibit" or "Schedule" shall be to an
Article, Section, subsection, Exhibit or Schedule of this Agreement, unless the
context requires otherwise. Unless the context otherwise requires, the words
"this Agreement," "hereof," "hereunder," "herein," "hereby," or words of similar
import shall refer to this Agreement as a whole and not to a particular Article,
Section, subsection, clause or other subdivision hereof. Whenever the context

                                    ARTICLE 2
                                  CONTRIBUTION

       2.1 CONTRIBUTION. On and subject to the terms and conditions of this
Agreement, EECI agrees to contribute, assign, transfer and convey to MLP, and
MLP agrees to accept from EECI, as a capital contribution, (i) the Membership
Interests and (ii) EECI's Partnership Interest, in each case following the
Conversion Step (collectively, the "OWNERSHIP INTERESTS").

                                    ARTICLE 3
                         CONSIDERATION FOR CONTRIBUTION

       3.1 CONSIDERATION. The parties acknowledge that the consideration to be
received by EECI for the transactions contemplated hereby is $929,100,000 (the
"TOTAL CONSIDERATION"), which amount consists of the Midcoast Related Debt, the
Cash Payment and the GP Contribution Credit. In consideration of the
contribution described in Section 2.1, upon Closing, (a) EECI shall (i) receive
the Cash Payment (which Cash Payment shall be funded by a lender in connection
with new debt incurred directly or indirectly by MLP and for which debt such
lender shall have recourse to EECI as the general partner of MLP) and (ii) be
deemed to have satisfied EECI's obligations (A) to pay for its acquisition of an
additional 1% general partner interest in MLP pursuant to the Reorganization
Agreement to the extent the value of such interest exceeds the value of EECI's
1.0101% general partner interest in OLP that is part of the consideration being
exchanged for such additional 1% general partner interest and (B) to make an
additional capital contribution pursuant to the MLP Partnership Agreement (after
giving effect to amendments thereto as a result of the Reorganization
Agreement), assuming an issuance by MLP of up to $469,500,000 of additional
units, (the sum of such deemed payment and capital contribution is herein
referred to as the "GP CONTRIBUTION CREDIT") and (b) MLP shall assume, directly
(in accordance with Section 3.2) and indirectly (as a result of the contribution
of the Ownership Interests pursuant to Section 2.1), the Midcoast Related Debt.
On or before the fifth (5th) day prior to the Closing, EECI shall provide
written notice to MLP setting forth the amount of the outstanding Midcoast
Related Debt as of the Closing.

       3.2    ASSUMPTION OF EECI MIDCOAST DEBT. Upon Closing, MLP shall assume
the EECI Midcoast Debt pursuant to the Assumption Agreement.

       3.3    POST-CLOSING ADJUSTMENT.

              (a)    PREPARATION OF THE CLOSING DATE BALANCE SHEET. As soon as
practicable after the Closing, and in any event within sixty (60) days following
the Closing Date, PricewaterhouseCoopers LLP ("PWC") shall prepare the Closing
Date Balance Sheet setting

                                        2
<Page>

forth the combined Capitalization of the Company Group calculated immediately
prior to the Effective Time (the "CLOSING DATE CAPITALIZATION"). Such Closing
Date Balance Sheet shall be prepared, except as this Agreement provides
otherwise, in accordance with GAAP (as in effect as of the date of this
Agreement) applied on a basis consistent with that used in, and presented on the
same basis as, the Pro Forma Closing Date Balance Sheet attached hereto as
Exhibit 3.3, except that the working capital for the Closing Date Balance Sheet
shall be determined in accordance with GAAP (as may be adjusted in connection
with Section 3.3(f)).

              (b) REVIEW OF CLOSING DATE BALANCE SHEET. PWC shall submit the
Closing Date Balance Sheet, when prepared, to MLP and EECI. Each of MLP and EECI
shall have the right, with its representatives and accountants other than PWC,
to review the work papers of PWC used in preparing the Closing Date Balance
Sheet and shall have reasonable access to the personnel of PWC for purposes of
verifying the accuracy and fairness of presentation and compliance with this
Agreement of the Closing Date Balance Sheet.

              (c) OBJECTIONS TO CLOSING DATE BALANCE SHEET. If MLP or EECI
disagrees with the calculation of the Closing Date Capitalization shown on the
Closing Date Balance Sheet, it shall, within 30 days after its receipt of the
Closing Date Balance Sheet, deliver a written notice to the other party (a
"DISAGREEMENT NOTICE"), setting forth its calculation of the Closing Date
Capitalization and specifying, in reasonable detail, those items or amounts in
the Closing Date Balance Sheet and/or the Closing Date Capitalization as to
which MLP or EECI, as applicable, disagrees and the reasons for such
disagreement. Each of MLP and EECI shall be deemed to have agreed with all items
and amounts contained in the Closing Date Balance Sheet and the Closing Date
Capitalization other than those specified in a timely Disagreement Notice. If
neither MLP nor EECI delivers a Disagreement Notice to the other party within
such 30-day period, MLP and EECI, as applicable, shall be deemed to have
accepted the Closing Date Balance Sheet and the Closing Date Capitalization,
whereupon the Closing Date Balance Sheet and the Closing Date Capitalization
shall become final and binding as to such non-objecting party.

              (d) RESOLUTION OF CLOSING DATE BALANCE SHEET DISPUTES. If a
Disagreement Notice is timely delivered pursuant to this Section 3.3, the
parties shall use their good faith efforts to reach agreement on the disputed
items or amounts in order to determine the adjustment to the Cash Payment. If
the parties do not resolve all disputed items or amounts within thirty (30) days
after delivery of the Disagreement Notice, then the disputed items and amounts
will be submitted for determination to a nationally recognized independent
accounting firm mutually selected by MLP and EECI or, if MLP and EECI cannot
agree, as recommended by PWC. EECI and MLP may submit to such accounting firm
any facts which they deem relevant to the determination. The written report of
such accounting firm shall be delivered to EECI and MLP within thirty (30) days
after such disputed items and amounts are submitted to such accounting firm for
determination. The determination of such accounting firm shall be final and
binding upon EECI and MLP for all purposes and shall not be subject to challenge
before any court of law or arbitration tribunal. EECI and MLP agree that
judgment may be entered upon the determination of such accounting firm in any
court having jurisdiction over the party against which such determination is to
be enforced. The fees and expenses of PWC and any other accounting firm (other
than an accounting firm retained by either MLP or EECI to review the Closing
Date Balance Sheet) shall be borne equally by EECI and MLP, with 50% of the
total of

                                        3
<Page>

such fees and expenses included as current liabilities on the Closing Date
Balance Sheet. Any fees and expenses of EECI's and MLP's own independent public
accountants incurred in connection with their review of the Closing Date Balance
Sheet shall be borne by the party retaining such independent public accountants.

              (e) TOTAL CONSIDERATION ADJUSTMENT. If the Closing Date
Capitalization, as finally determined pursuant to this Section 3.3, is less than
the Target Capitalization, then EECI will pay to MLP, within two (2) Business
Days, by wire transfer of immediately available funds, the amount of such
shortfall plus interest from the Closing Date on such shortfall at the Agreed
Rate. If the Closing Date Capitalization, as finally determined pursuant to this
Section 3.3, is greater than the Target Capitalization, then MLP will pay to
EECI, within two (2) Business Days, by wire transfer of immediately available
funds, the amount of such excess plus interest from the Closing Date on such
excess at the Agreed Rate. Any payment under this Section 3.3 shall be deemed an
adjustment of the Total Consideration. If MLP is required to make payment to
EECI pursuant to this Section 3.3(e), then such payment shall be funded by a
lender in connection with new debt incurred directly or indirectly by MLP and
such lender shall have recourse to EECI as the general partner of MLP for such
debt.

              (f) For the purposes of this Section 3.3, "CAPITALIZATION" shall
be defined as sum of (x) the combined total assets minus the combined total
liabilities of the Company Group, in each case without duplication of amounts
plus (y) the Midcoast Related Debt less the EECI Midcoast Debt, adjusted as
follows:

                     (1)    elimination of the amount of the accounts receivable
(less any reserves) (A) attributable to the Bamagas Firm Capacity Payment, to
the extent such accounts receivable relate to time periods prior to the Closing,
and (B) arising in connection with the Contracts described in Schedule 3.3(f),
to the extent such accounts receivable relate to the time period prior to
Closing; it being agreed that no other accounts receivable shall be eliminated
(whether or not past due);

                     (2)    elimination of the Excluded Assets;

                     (3)    elimination of the Liabilities of the Excluded
                            Subsidiaries;

                     (4)    without giving effect to any casualty losses
occurring from and after the date of this Agreement until Closing or any
insurance proceeds received therefor;

                     (5)    without giving effect to changes in GAAP between the
date of this Agreement and the Closing Date; and

                     (6)    the amount of other comprehensive income and related
offsetting assets and liabilities shall be the same as in the Pro Forma Closing
Date Balance Sheet; and

                     (7)    the amount of the deferred income taxes and related
offsetting adjustment to retained earnings shall be the same as in the Pro Forma
Closing Date Balance Sheet.

                                        4
<Page>

       3.4 GOODWILL CLOSING ADJUSTMENT. Prior to the Closing, EECI shall cause
an independent third party to allocate, as of the Closing Date, the Total
Consideration among the Assets using the residual method as specified under
Section 1060 of the Code (the "APPRAISAL"). If the value of the Midcoast
Goodwill is determined by the Appraisal to be greater than $217,500,000, then on
or before the 30th day following the Closing, EECI shall pay to MLP an amount
equal to the product of (x) 0.182 multiplied by (y) the difference between (A)
$207,500,000 and (B) the actual value of the Midcoast Goodwill determined by the
Appraisal. If the value of the Midcoast Goodwill is determined by the Appraisal
to be less than $197,500,000, then, on or before the 30th day following the
Closing, MLP shall pay EECI an amount equal to the product of (x) 0.182
multiplied by (y) the difference between (A) the actual value of the Midcoast
Goodwill determined by the Appraisal and (B) $207,500,000. Any payment under
this Section 3.4 shall be deemed an adjustment to the Total Consideration.

expected, individually or in the aggregate, to have a Material Adverse Effect,
to the knowledge of EECI, (i) the business operations of each of the members of

interfere with compliance by any member of the Company Group with Environmental
Laws, (ii) no member of the Company Group is required by Environmental Laws to
conduct any removal, remediation, or similar corrective action, (iii) there is
no obligation, undertaking or Liability arising out of or relating to
Environmental Laws that any member of the Company Group has agreed to, assumed
or retained, by contract or otherwise, or that has been imposed on any member of
the Company Group by any writ, injunction, decree, order or judgment, (iv) there
are no Actions pending or threatened against any member of the Company Group

and any Group of which the Company or any member of the Company Group or any
predecessor thereof is or was a member which are or have become due for all
periods ending on or before the date hereof have been timely paid in full; the
amounts of Taxes for which provision has been made in the Recent Date Balance
Sheet (as adjusted subsequently for operations in the ordinary course of
business) will be sufficient to cover the payment of all Taxes, whether or not
assessed or disputed, which are, or are hereafter found to be, or to have been,
due by or with respect to all members of the Company Group up to and through the
periods ending on the dates thereof; there are and, as of the Closing, will be,
no encumbrances on any Assets that arose in connection with any failure (or
alleged failure) by any member of the Company Group to pay any Tax.

                     (2)    The Company and/or the Company Group and their
predecessors have, in all material respects (i) withheld amounts from the

member, is currently under audit by any Taxing authority and, except as could
not reasonably be expected to have a Material Adverse Effect (determined without
giving effect to the Conversion Step or the Restructuring Actions), no taxing
authority has advised any member of the Company Group that it has assessed or
intends to assess any additional Taxes for any Tax period ending on or before

knowledge.

                     (4)    There are no outstanding agreements or waivers by or
with respect to any member of the Company Group that extend the statutory period
of limitations applicable to any Tax Returns or the payment of, or assessment
of, any Tax, or containing any agreements or arrangements with any Taxing
authority that may affect Taxes of any member of the Company Group following the
Closing.

                     (5)    No member of the Company Group is a party to or

date of inception and prior to the conversion to a limited partnership as
contemplated by Article 6 hereof properly treated as a corporation pursuant to

and (ii) no answer given in response to any such questions shall constitute a
representation, warranty, covenant or agreement of EECI or any member of the
Company Group.

asbestos or asbestos containing materials or naturally occurring radioactive
materials ("NORM") and that special procedures may be required for the

and other Liabilities associated with the assessment, remediation, removal,
abatement, transportation and disposal of the asbestos, asbestos containing
materials or NORM associated with the Sulphur River Assets and for which EECI is

Liabilities, the Company will be subordinated to any rights of EECI to seek
recovery thereof from that prior owner.

warranty set forth herein. Without limiting the respective warranties,
representations, covenants and agreements of the parties contained herein, each
of the parties agrees to use its reasonable efforts (and to cause its Affiliates
to use their reasonable efforts) to refrain from taking any action within its

advise each other in writing if such party obtains knowledge of the occurrence
of any matter or event that, to its knowledge, could reasonably be expected to
result in a breach of any of such party's representations, warranties, covenants
or agreements in this Agreement. In connection with the continuing operations of
the Company and the Company Subsidiaries between signing of this Agreement and
the Closing, EECI and the Company shall use reasonable efforts to consult in
good faith on a regular and frequent basis with the representatives of MLP to
report material operational developments and the general status of ongoing
operations of the Company and the Company Subsidiaries. EECI and MLP acknowledge
that any such consultation shall not constitute (i) a waiver by MLP or EECI of
any rights it may have under this Agreement or any Transaction Documents or (ii)
any warranty or representation by EECI.

       9.5 PENDING REGULATORY RATE CASES. Prior to the Closing, EECI will not

GR-2001-382 or (iv) the litigation pending in Johnson County, Kansas in Case No.
99-C06574 or any appeal or remand of such litigation (the Actions described in
clauses (i) through (iv) being "Pending Regulatory Cases") from the date hereof
until the Effective Time. EECI promptly on receipt shall provide to MLP copies
of any notices, correspondence, orders or other documents in respect of the
Pending Regulatory Cases that it receives from any third party or Governmental
Authority.

       9.6    CASUALTY LOSS.

              (a) If all or any material portion of the Assets are damaged or
destroyed by fire or other casualty before the Closing, either party may, at its
option, terminate this Agreement by written notice to the other party prior to

Agreement as aforesaid, the parties shall proceed to close the transactions
contemplated hereby, in which event EECI shall assign to MLP, or cause to be
assigned, all of the EECI Group's right, title and interest, if any, in any
claim under any applicable insurance policies in respect of such casualty. If
the total amount of any such insurance proceeds is not sufficient to fully
repair and/or replace the damaged facilities to return them to their pre-damage
or destruction operating condition and repair, the amount of such shortfall
shall, at the option of EECI, either be paid by EECI to MLP or will reduce the
amount of Total Consideration by the amount of such shortfall.

              (b) If the casualty loss does not involve all or any material
portion of the Assets, then the parties shall be obligated to close the
transaction contemplated herein according to the terms hereof, notwithstanding
such casualty loss, and EECI shall, at the election of EECI, either: (i) repair
and/or replace the damaged facilities to their pre-damage or destruction
operating condition and repair prior to Closing, at its expense; or (ii) (A) pay
the deductible due under the insurance policy or policies insuring the same and
deliver or assign or cause to be delivered or assigned to MLP, at Closing, any
and all of the insurance proceeds received by any member of the EECI Group or
the rights of any member of the EECI Group to proceeds attributable to such
casualty loss and (B) pay to MLP any other amount required to repair and/or
replace the damaged facilities in excess of such insurance proceeds.

              (c) For the purposes of this Section, a "MATERIAL PORTION" means
any casualty loss where the uninsured portion of the Company Group's Liability
associated therewith is equal to or greater than $20,000,000. For purposes of
this Section 9.6(c) only, the term "Liability" shall include indirect and
consequential losses (including any losses on account of lost profits or
opportunities or business interruption).

       9.7 FURTHER ASSURANCES. EECI and MLP each agrees that from time to time
after the Closing Date, each of them will execute and deliver or cause their
respective Affiliates (including each member of the Company Group) to execute
and deliver such further instruments, and take (or cause their respective
Affiliates, including each member of the Company Group, to take) such other
action, as may be necessary to carry out the purposes and intents of this
Agreement. Nothing in this Section shall cause any representation, warranty,
covenant or agreement contained in other Sections or provisions of this
Agreement to survive later than the time stipulated for the survival of such
representation, warranty, covenant or agreement in Section 13.1.

       9.8 RECORDS. MLP agrees to maintain (or cause each member of the Company
Group to maintain) the Company Records until the fifth anniversary of the
Closing Date (or for such longer period of time as EECI shall advise MLP in
writing is necessary in order to have Company Records available with respect to
open years for tax audit purposes), or, if any of the Company Records pertain to
any claim or dispute pending on the fifth anniversary of the Closing Date, MLP
shall maintain any of the Company Records designated by EECI until such claim or
dispute is finally resolved and the time for all appeals has been exhausted. MLP
shall provide (and cause each member of the Company Group to provide) EECI and
its representatives reasonable access to and the right to copy the Company
Records for the purposes of (i) preparing and delivering any accounting provided
for under this Agreement and adjusting, prorating and settling the charges and
credits provided for in this Agreement, (ii) complying with any Law affecting
EECI's interest in the Company Shares, the Membership Interests or EECI's

                                       31
<Page>

Partnership Interest, Holdings LLC's interest in the Holdings' Partnership
Interest or the Company's or the Company Subsidiaries' interest in the Assets
prior to the Closing Date, (iii) preparing Tax returns, (iv) responding to or
disputing any Tax audit or (v) asserting, defending or otherwise dealing with
any claim or dispute under this Agreement or with respect to the Company Group
or the Assets. During the period set forth in this Section 9.8, none of MLP, the
Company Group or any of their Affiliates shall destroy any Company Records
without giving EECI sixty (60) days' advance written notice thereof and the
opportunity, at EECI's expense, to obtain such Company Records prior to their
destruction.

       9.9 MAINTENANCE OF MIDCOAST INDEMNIFICATION PROVISIONS. In addition to
and without limiting the Company's and MLP's respective obligations under
Articles 14 and 15, the Company shall perform all the obligations of the
"Surviving Corporation," "the Company" and the "Parent" under Section 5.4 of the
Midcoast Agreement (as such terms are defined therein). On or prior to the
Closing, EECI shall cause Enbridge, Inc. to assign all of its rights, if any,
under the Midcoast Agreement to the Company and upon the receipt of such
assignment the Company agrees to perform all of Enbridge, Inc.'s obligations, if
any, under the Midcoast Agreement.

       9.10 COMPANY NAME; LOGOS, ETC. At Closing, EECI shall execute and
deliver, or cause to be executed and delivered, to the Company a license
agreement in the form attached hereto as Exhibit 9.10 pursuant to which EECI or
an Affiliate of EECI shall grant to each member of the Company Group a license

between a member of the Company Group and EECI or an Affiliate of EECI (other
than a member of the Company Group) shall be terminated on or before Closing,
and the Company shall, and/or shall cause members of the Company Group, to enter
into new services agreements with EECI or an Affiliate of EECI (other than a
member of the Company Group) (collectively, "NEW SERVICES AGREEMENT") on the
same economic terms as those agreements listed in SCHEDULE 9.11.

       9.12 HSR FILINGS. Within ten (10) Business Days after the date hereof,
each party will file or cause its ultimate parent entity (within the meaning of
the HSR Act) to file all materials required to be filed by it under the HSR Act

all material respects with the requirements of the HSR Act.

       9.13 NOTICE OF BASIS FOR INDEMNIFICATION CLAIMS. So long as EECI or any
of its Affiliates is the general partner of MLP, whenever EECI or any of its
Affiliates obtains knowledge that MLP has been damaged and may have a claim

give written notice of that claim, described in reasonable detail, to the Audit,
Finance and Risk Committee of MLP.

       9.14 ROLE OF SPECIAL COMMITTEE. With respect to (A) any action, notice,
consent, approval or waiver that is required to be taken or given or may be
taken or given by MLP prior to Closing pursuant to Sections 3.3, 6.2, 9.1, 9.2,

MLP. With respect to any notice required to be given or that may be given to MLP
prior to the Closing and any consultation to be undertaken with MLP pursuant to
Section 9.4 or 9.5, such notice shall be given to, and such consultation shall
be undertaken with, the Special Committee of MLP acting on behalf of MLP.
Neither this Agreement nor any of the Transaction Documents may be amended prior
to the Closing without the consent of the Special Committee of MLP on behalf of
MLP.

       9.15 KPC COST OF SERVICE. On or before each KPC Payment Date, EECI agrees
to pay to MLP or its designee an amount equal to the KPC Cost of Service
Difference ("KPC SERVICE AMOUNT PAYMENT"). Notwithstanding anything herein to
the contrary, if MLP or its Affiliates are permitted by FERC, upon a final
non-appealable order in the KPC Rate Case, to impose a surcharge relating to any
KPC Service Amount previously collected during the KPC Payment Obligation
Period, then the amount of such surcharge actually received by MLP or its
designee (or any of MLP's Affiliates) shall be distributed in the following
manner:

              (i) first, MLP and EECI shall each receive 50% of the amount of
such surcharge until MLP has received an amount equal to the KPC Accumulated
Payment Deficiency;

              (ii) second, EECI shall receive 100% of the amount of any
remaining surcharge, if any, until the total payments to EECI, including amounts
paid under clause (i) above, equal the Cumulative KPC Service Amount Payments;
and

              (iii)  third, MLP shall receive any remaining surcharge, if any.

       9.16 SUBSTITUTE GUARANTIES. MLP acknowledges the list of Guaranties set
forth in SCHEDULE 9.16 and agrees to use its reasonable efforts prior to the
Closing to cooperate with EECI and/or its Affiliates to terminate each such
Guaranty (including offering to substitute a Guaranty of the MLP or one of its
Affiliates for such Guaranty) and procure from the existing obligee the release
of the guarantor that is a party to such Guaranty from any and all liability
from and under such Guaranty, which release shall take effect at the Closing. To
the extent that EECI and/or its Affiliates are not able to terminate any such
Guaranty and obtain any such release prior to the Closing in accordance with
clause (ii) of the preceding sentence, MLP agrees (a) to continue to use its
reasonable efforts thereafter to effect such a termination and release and (b)
to indemnify the EECI Group to the extent of any Liabilities that such guarantor
may incur or suffer as a result of being required to perform any obligations
under, or to defend against any claim made or threatened to be made in
connection with, any such Guaranties from and after the Closing. This
indemnification shall be in addition to the indemnification provided pursuant to
Section 15.1.

       9.17 RIGHTS TO BAMAGAS FIRM CAPACITY PAYMENTS. If any payment is made by
EECI to MLP in connection with its indemnity obligation under Section 15.2(c),
then, contemporaneously with such payment, MLP shall cause Bamagas to assign any
and all rights to collect from Calpine and its Affiliates the Bamagas Firm
Capacity Payments in respect of which such payment was made or, if such rights
are non-assignable, MLP shall cause Bamagas to pursue, at

                                       33
<Page>

the direction of EECI and at EECI's sole cost and expense, all remedies
available at law or in equity against Calpine for such Bamagas Firm Capacity
Payments.

       9.18 CERTIFIED COPIES OF CERTAIN DOCUMENTS. As promptly as practicable
following (i) any of the Restructuring Actions involving a merger or conversion
of any Company Subsidiary or (ii) the Conversion Step, EECI shall provide to MLP
copies of the articles and certificates of merger or conversion or similar
filings with respect to such actions made with applicable Governmental
Authorities, certified by the applicable Governmental Authority.

       9.19 MIDCOAST RELATED DEBT. In connection with the Midcoast Related Debt,
on or prior to the Closing, EECI shall obtain from its Affiliates that are the
payees under such debt all consents required from such Affiliates thereunder to
consummate the transactions contemplated hereby, including the assumption by MLP
of the EECI Midcoast Debt.

       9.20   INTENTIONALLY DELETED.

       9.21 UNCOLLECTED ACCOUNTS RECEIVABLE. With respect to any accounts
receivable that are eliminated from the computation of Capitalization under
Section 3.3(f), at EECI's request, MLP shall pursue or cause a member of the
Company Group to pursue for EECI's benefit, at EECI's direction and sole cost
and expense, all remedies available at law or in equity against the payors of
such accounts receivable to collect such amounts. MLP shall pay to EECI any
amounts received from such payors in payment of any such receivables.

       9.22 MIDCOAST RELATED DEBT. EECI shall not permit the Company Group to
incur additional New Intercompany Debt so as to cause the aggregate principal
and accrued and unpaid interest under the Midcoast Related Debt that will be

                                   ARTICLE 10
                                   TAX MATTERS

       10.1 ASSET CONTRIBUTION CHARACTERIZATION FOR FEDERAL INCOME TAX PURPOSES.
The parties intend that the separate existence of the Company apart from EECI
shall be disregarded for federal income Tax purposes (and for purposes of any
state income Tax for which such treatment is permitted or required) at the time
of the Closing and that the contribution of the Ownership Interests shall, for
purposes of such Taxes, constitute a contribution to MLP by EECI of the assets
owned by the Company at the time of the Closing subject to the provisions of
Section 721 of the Code. Unless required by applicable Tax Law, neither party
shall take any action inconsistent with such treatment, including, without
limitation, the filing of any election under Treas. Reg. 301.7701-3 for a period
that includes the Closing. EECI and MLP will allocate the Total Consideration
among the assets of the Company Subsidiaries as set forth on SCHEDULE 10.1.

       10.2   LIABILITY FOR TAXES.

              (a) Except to the extent such Taxes are accrued as a Liability on
the Closing Date Balance Sheet, EECI shall be liable for, and shall indemnify
and hold MLP, the Company and their Affiliates harmless from, (i) any Taxes
caused by or resulting from the Restructuring

                                       34
<Page>

Actions, the Conversion Step and the Contribution Step, and any other actions
taken in anticipation or pursuance thereof, (ii) any Taxes imposed on or
incurred by any member of the Company Group arising out of the inclusion of any
member of the Company Group in any Group by reason of Treasury Regulation
ss.1.1502-6 or any analogous state, local or foreign law or regulation; (iii)
any Taxes imposed on or incurred by any member of the Company Group (or any
Group with respect to the taxable items of any member of the Company Group) for
any taxable period ending before or including the Closing Date (or the portion,
determined as described in paragraph (c) of this Section 10.2, of any such Taxes
for any taxable period beginning on or before and ending after the Closing Date
which is allocable to the portion of such period occurring on or before the
Closing Date (the "PRE-CLOSING PERIOD")) except for Taxes arising from
transactions by any member of the Company Group outside the ordinary course of
business after the Closing, (iv) any Taxes resulting from the income, business,
property or operations of the Excluded Assets, (v) any Taxes imposed on EECI or
a Group that includes EECI with respect to the assets and operations of any
member of the Company Group for any period or portion of a period during the
Midcoast Ownership Period, (vi) any Taxes arising from any breach by EECI of its
representations and warranties contained in Section 4.1(q) or its covenants in
Section 10.1, and (vii) any reasonable attorneys' fees or other reasonable costs
incurred by MLP, any member of the Company Group or any Affiliate thereof in
connection with any payment from EECI under this Section 10.2(a).

              (b) From and after the Closing, MLP shall be liable for, and shall
indemnify and hold EECI and its Affiliates (other than the Company Group)
harmless from, (i) any Taxes imposed on or incurred by or with respect to any
member of the Company Group for which EECI is not liable under Section 10.2(a),
(ii) any Taxes arising from any breach by MLP of its covenants in Section 10.1,
and (iii) any reasonable attorneys' fees or other reasonable costs incurred by
EECI or any Affiliate thereof in connection with any payment from MLP under this
Section 10.2(b).

              (c) Whenever it is necessary for purposes of Section 10.2(a) or
Section 10.2(b) to determine the portion of any Taxes imposed on or incurred by
any member of the Company Group (or any Group) for a taxable period beginning on
or before and ending after the Closing Date which is allocable to the
Pre-Closing Period, the determination shall be made, in the case of property, ad
valorem or similar Taxes (which are not measured by, or based upon, production)
or franchise or capital Taxes (which are not measured by, or based upon, net
income), by multiplying such Taxes by a fraction, the numerator of which is the
number of days in the Pre-Closing Period and the denominator of which is the
total number of days in such Tax period, and, in the case of other Taxes, by
assuming that the Pre-Closing Period constitutes a separate taxable period of
the Company and by taking into account the actual taxable events occurring
during such period (except that exemptions, allowances and deductions for a
taxable period beginning on or before and ending after the Closing Date that are
calculated on an annual or periodic basis, such as the deduction for
depreciation in any state jurisdiction that does not follow the federal income
tax characterization described in Section 10.1 above, shall be apportioned to
the Pre-Closing Period ratably on a per diem basis).

              (d) EECI and MLP will, to the extent permitted by applicable Law,
elect with the relevant taxing authorities to (i) apply the characterization of
the contribution of the Ownership Interests described in Section 10.1 above, or,
(ii) if such an election is not available,

                                       35
<Page>

to close all taxable periods of any member of the Company Group as of the close
of business on the Closing Date.

              (e) MLP agrees to pay to EECI any refund received after the
Closing Date by MLP or its Affiliates, including the Company Group, in respect
of any Taxes for which EECI is liable under Section 10.2(a), except to the
extent such refund is shown as an asset on the Closing Date Balance Sheet. EECI
agrees to pay to MLP any refund received by EECI or its Affiliates (other than
any member of the Company Group) in respect of any Taxes for which MLP is liable
under Section 10.2(b). The parties shall cooperate in order to take all
necessary steps to claim any such refund. Any such refund received by a party or
its Affiliate for the account of the other party shall be paid to such other
party within thirty (30) days after such refund is received.

       10.3 TAX PROCEEDINGS. In the event MLP, any member of the Company Group
or any of their Affiliates receives notice (the "PROCEEDING NOTICE") of any
examination, claim, adjustment or other proceeding with respect to the Liability
of any member of the Company Group for Taxes for any period for which EECI is or
may be liable under Section 10.2(a), MLP shall notify EECI in writing thereof
(the "MLP NOTICE") no later than the earlier of (a) thirty (30) days after the
receipt by MLP, any member of the Company Group or any of their Affiliates of
the Proceeding Notice, or (b) ten (10) days prior to the deadline for responding
to the Proceeding Notice as to any such Taxes for which EECI is or may be liable
under Section 10.2(a). EECI shall be entitled at its expense to control or
settle the contest of such examination, claim adjustment or other proceeding,
provided EECI notifies MLP in writing that it desires to do so no later than the
earlier of (i) thirty (30) days after receipt of the MLP Notice or (ii) five (5)
days prior to the deadline for responding to the Proceeding Notice. EECI may
not, without the consent of MLP (which consent MLP may reasonably withhold),
agree to any settlement which would result in an increase in the amount of Taxes
for which MLP, its partners or any member of the Company Group is or may be
liable under Section 10.2(b). The parties shall cooperate with each other and
with their respective Affiliates, and will consult with each other, in the
negotiation and settlement of any proceeding described in this Section 10.3.

       10.4   TAX RETURNS.

              (a) EECI shall cause to be included in the consolidated federal
income Tax Returns (and the state income Tax Returns of any state that permits
consolidated, combined or unitary income Tax Returns) of the EECI Tax Group (as
defined herein) for all periods ending on or before the Closing Date, all Tax
items of all members of the Company Group which are required to be included
therein, shall cause such Tax Returns to be timely filed with the appropriate
taxing authorities, and shall be responsible for the timely payment (and
entitled to any refund) of all Taxes due with respect to the periods covered by
such Tax Returns. For purposes of this Agreement "EECI TAX GROUP" means the
affiliated group of corporations within the meaning of section 1504 of the
Internal Revenue Code of 1986, as amended, which files a consolidated federal
income Tax Return and as to which EECI is the common parent, and, in the case of
any combined or unitary Tax Return, the group of corporations filing such Tax
Return that includes EECI or its operations.

              (b) With respect to any Tax Return covering a taxable period
ending on or before the Closing Date that is required to be filed after the
Closing Date with respect to any

                                       36
<Page>

member of the Company Group that is not described in paragraph (a) above, EECI
shall cause such Tax Return to be prepared, shall cause to be included in such
Tax Return all Tax items required to be included therein, shall cause such Tax
Return to be filed timely with the appropriate taxing authority, and shall be
responsible for the timely payment (and entitled to any refund) of all Taxes due
with respect to the period covered by such Tax Return.

              (c) With respect to any Tax Return covering a taxable period
beginning on or before the Closing Date and ending after the Closing Date that
is required to be filed after the Closing Date with respect to the Company Group
and their assets and operations, MLP shall cause such Tax Return to be prepared,
shall cause to be included in such Tax Return all Tax items required to be
included therein, shall file timely such Tax Return with the appropriate taxing
authority, and shall be responsible for the timely payment of all Taxes due with
respect to the period covered by such Tax Return. MLP shall determine, in
accordance with the provisions of Section 10.2(c), the amount of Tax due with
respect to the period prior to and including the Closing Date (the
"CONTRIBUTOR'S TAX") and shall notify EECI of its determination of the
Contributor's Tax. EECI shall pay to MLP an amount equal to the Contributor's
Tax not later than five days after the filing of such Tax Return. Any refund
attributable to Tax Returns filed pursuant to this Section 10.4(c) shall be
apportioned between MLP and EECI in a manner consistent with calculation of the
Contributor's Tax.

       10.5 TAX ALLOCATION ARRANGEMENTS. Effective as of the Closing, all
Liabilities and obligations between any member of the Company Group, on the one
hand, and EECI and any Affiliates thereof (other than any member of the Company
Group), on the other hand, under any Tax indemnity, sharing, allocation or
similar agreement or arrangement in effect prior to the Closing shall be
extinguished in full, and any Liabilities or rights existing under any such
agreement or arrangement shall cease to exist and shall no longer be
enforceable. EECI and its Affiliates shall execute any documents necessary to
effectuate the provisions of this Section 10.5.

       10.6 COOPERATION AND EXCHANGE OF INFORMATION. Each party will provide, or
cause to be provided, to the other party copies of all correspondence received
from any Governmental Authority by such party or any of its Affiliates in
connection with the Liability of any member of the Company Group for Taxes for
any period for which such other party is or may be liable under Section 10.2(a)
or Section 10.2(b). The parties will provide each other with such cooperation
and information as they may reasonably request of each other in preparing or
filing any Tax Return or claim for refund, in determining a Liability or a right
of refund or in conducting any audit or other proceeding in respect of Taxes
imposed on the parties or their respective Affiliates. The parties and their
Affiliates will preserve and retain all Tax Returns, schedules, work papers and
all material records or other documents relating to any such Tax Returns,
claims, audits or other proceedings until the expiration of the statutory period
of limitations (including extensions) of taxable periods to which such documents
relate and until the final determination of any payments which may be required
with respect to such periods under this Agreement and shall make such documents
available to the other party or any Affiliate thereof, and their respective
officers, employees and agents, upon reasonable notice and at reasonable times,
it being understood that such representatives shall be entitled to make copies
of any such books and records relating to any member of the Company Group as
they shall deem necessary. Any information obtained pursuant to this Section
10.6 shall be kept confidential,

                                       37
<Page>

except as may be otherwise necessary in connection with the filing of Tax
Returns or claims for refund or in conducting any audit or other proceeding.
Each party shall provide the cooperation and information required by this
Section 10.6 at its own expense.

       10.7   REMEDIAL ALLOCATION METHOD. EECI shall cause the MLP to elect the
remedial allocation method under Treas. Reg.ss.1.704-3(d), if available, with
respect to the Assets, except as provided in Section 10.10.

effect without limitation as to time.

       10.9 CONFLICT. In the event of a conflict between the provisions of this
Article 10 and any other provisions of this Agreement, the provisions of this
Article 10 shall control.

       10.10  GOODWILL. The parties agree that the Midcoast Goodwill shall not
be amortized for tax purposes by the MLP.

       13.1 SURVIVAL. (a) The representations, warranties, covenants and
agreements of the parties set forth herein and in any certificate delivered in
connection herewith with respect to any of those representations, warranties,
covenants and agreements will survive the Closing and the Effective Time until
the day that is two years from the Effective Time, whereupon they will terminate
and expire, except as follows:

                  (1)      the representations and warranties of EECI:

                                       41
<Page>

                            (A) under Sections 4.1(q), 4.1(y) and 4.1(gg), shall
                     survive until the 90th day after the expiration of the
                     applicable statues of limitations (including all periods of
                     extension and tolling); and

                            (B) under Sections 4.1(e) and 4.1(r), shall survive
                     until the day that is four years from the Effective Time;

                            (A) under Sections 9.6, 9.7, 9.13 and 9.15 and
                     Articles 10, 13, 14, 15 (other than Section 15.2(c) and
                     Section 15.2(d)) and 17 shall survive indefinitely or for
                     such shorter period as may be stipulated in such
                     provisions;

                            (B) under Section 15.2(c) shall survive until
                     Calpine has paid the Bamagas Firm Capacity Payment for a
                     three-month period (whether or not such three-month period
                     occurs prior to or after the Closing) without any written
                     communication asserting that such payment is subject to
                     refund to Calpine because of the Calpine Dispute; and

                            (C) under Section 15.2(d) shall survive until the
                     day that is four years from the Effective Time;

                     (3) the covenants and agreements of MLP and/or the Company,
              as the case may be, under Sections 8.1, 9.7, 9.8, 9.9, 9.15, 9.16,
              9.17 and 9.21 and Articles 7, 10, 13, 14, 15 and 17 shall survive
              indefinitely or for such shorter period as may be stipulated in
              such provisions;

provided, however, that the applicable time period specified above in the case
of any representation, warranty, covenant or agreement of EECI will be computed
excluding from that computation any time during which EECI is in violation of
Section 9.13 with respect to any indemnification claim arising out of the breach
of such representation, warranty, covenant or agreement.

                     (b)    After a representation, warranty, covenant or
agreement has expired under Section 13.1(a), no damage claim will or may be made
or prosecuted, through an Action or otherwise, by any Person who would have been
entitled to damages hereunder on the basis of that representation, warranty,
covenant or agreement prior to its termination and expiration, provided that no
damage claim based on a representation, warranty, covenant or agreement
hereunder written notice of which damage claim is presented prior to the
termination and expiration of that representation, warranty, covenant or
agreement to the Person or Persons from which damages are then being or
thereafter may be sought on the basis of that representation, warranty, covenant
or agreement will be affected in any way by that termination and expiration.

       14.1   DISCLAIMER OF WARRANTIES AND REPRESENTATIONS. NOTWITHSTANDING
ANYTHING TO THE CONTRARY CONTAINED IN ANY OTHER PROVISION OF

                                       42
<Page>

THIS AGREEMENT, IT IS THE EXPLICIT INTENT OF EACH PARTY HERETO THAT EECI IS NOT
MAKING ANY REPRESENTATION OR WARRANTY WHATSOEVER, EXPRESS, IMPLIED, STATUTORY OR
OTHERWISE, BEYOND THOSE REPRESENTATIONS OR WARRANTIES EXPRESSLY GIVEN IN THIS
AGREEMENT. WITHOUT LIMITING THE GENERALITY OF THE IMMEDIATELY PRECEDING SENTENCE
AND WITHOUT LIMITING THE EXPRESS REPRESENTATIONS AND WARRANTIES OF EECI
CONTAINED IN THIS AGREEMENT, EECI HEREBY EXPRESSLY DISCLAIMS AND NEGATES ANY
REPRESENTATION OR WARRANTY, EXPRESS OR IMPLIED, AT COMMON OR CIVIL LAW, BY
STATUTE OR OTHERWISE, RELATING OR WITH RESPECT TO (A) ANY IMPLIED OR EXPRESS
WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE, OR OF
CONFORMITY TO MODELS OR SAMPLES OF MATERIALS, (B) ANY INFRINGEMENT BY EECI, ANY
OF ITS AFFILIATES OR ANY OF THE COMPANY GROUP OF ANY PATENT OR PROPRIETARY RIGHT
OF ANY THIRD PARTY, (C) ANY ENVIRONMENTAL MATTERS (INCLUDING ANY ENVIRONMENTAL
CONDITION), (D) THE ACCURACY OR COMPLETENESS OF THE INFORMATION, RECORDS, DATA
AND INTERPRETATIONS NOW, HERETOFORE OR HEREAFTER MADE AVAILABLE TO MLP IN
CONNECTION WITH THIS AGREEMENT BY EECI, ANY AFFILIATE OF EECI, ANY OF COMPANY
GROUP OR ANY DIRECTOR, OFFICER, EMPLOYEE, AGENT, REPRESENTATIVE, INVESTMENT
BANKER, COUNSEL, CONSULTANT OR ADVISOR OF SUCH PERSONS, AND (E) THE COMPANY'S OR
ANY OF THE COMPANY SUBSIDIARIES' TITLE TO ANY OF THE ASSETS.

       14.2 DAMAGES. NOTWITHSTANDING ANYTHING CONTAINED TO THE CONTRARY IN ANY
OTHER PROVISION OF THIS AGREEMENT, EECI AND MLP AGREE THAT THE RECOVERY BY
EITHER PARTY HERETO OF ANY DAMAGES OR OTHER LIABILITIES SUFFERED OR INCURRED BY
IT AS A RESULT OF ANY BREACH BY THE OTHER PARTY OF ANY OF ITS REPRESENTATIONS,
WARRANTIES OR OBLIGATIONS UNDER THIS AGREEMENT SHALL BE LIMITED TO THE ACTUAL
DAMAGES AND/OR LIABILITIES SUFFERED OR INCURRED BY THE NON-BREACHING PARTY AS A
RESULT OF THE BREACH BY THE BREACHING PARTY OF ITS REPRESENTATIONS, WARRANTIES
OR OBLIGATIONS HEREUNDER AND IN NO EVENT SHALL THE BREACHING PARTY BE LIABLE TO
THE NON-BREACHING PARTY FOR ANY INDIRECT, CONSEQUENTIAL, SPECIAL, EXEMPLARY OR
PUNITIVE DAMAGES (INCLUDING ANY DAMAGES ON ACCOUNT OF LOST PROFITS OR
OPPORTUNITIES OR BUSINESS INTERRUPTION) SUFFERED OR INCURRED BY THE
NON-BREACHING PARTY AS A RESULT OF THE BREACH BY THE BREACHING PARTY OF ANY OF
ITS REPRESENTATIONS, WARRANTIES OR OBLIGATIONS HEREUNDER. For purposes of the
foregoing, actual damages may however, include indirect consequential, special,
exemplary or punitive damages to the extent (i) the injuries or losses resulting
in or giving rise to such damages are incurred or suffered by a Person that is
not an Indemnified Person or an Affiliate of any Indemnified Person and (ii)
such damages are recovered against an Indemnified Person by a Person that is not
an Indemnified Person or an Affiliate of any Indemnified Person. This Section
14.2 shall operate only to limit a party's liability and shall not operate to
increase or expand any contractual obligation of a party

                                       43
<Page>

hereunder or cause any contractual obligation of a party hereunder to survive
longer than provided in Section 13.1.

       14.3 ENVIRONMENTAL RELEASE. From and after Closing but subject to EECI's
indemnity obligations under Section 15.2 as long as such indemnity survives with
respect to any Environmental Liability, the MLP Indemnified Persons shall have
no rights to recovery or indemnification for Environmental Liabilities or any
environmental matters under this Agreement or Law (including any Environmental
Law), and all rights or remedies which any MLP Indemnified Person may have at or
under Law (including any Environmental Law) with respect to any Environmental
Liabilities or environmental matters are expressly waived. FROM AND AFTER
CLOSING, BUT WITHOUT LIMITING OR RELEASING EECI'S INDEMNITY OBLIGATIONS UNDER
SECTION 15.2, MLP AND ALL MLP INDEMNIFIED PERSONS DO HEREBY AGREE, WARRANT AND
COVENANT TO RELEASE, ACQUIT AND FOREVER DISCHARGE EECI AND ALL EECI INDEMNIFIED
PERSONS FROM ANY AND ALL CLAIMS, DEMANDS AND CAUSES OF ACTION OF WHATSOEVER
NATURE, INCLUDING WITHOUT LIMITATION ALL CLAIMS, DEMANDS AND CAUSES OF ACTION
FOR CONTRIBUTION AND INDEMNITY UNDER STATUTE, COMMON OR CIVIL LAW, WHICH COULD
BE ASSERTED NOW OR IN THE FUTURE AND THAT RELATE TO OR IN ANY WAY ARISE OUT OF
ENVIRONMENTAL LIABILITIES OR ENVIRONMENTAL MATTERS. FROM AND AFTER CLOSING AND
EXCEPT FOR THE RIGHTS AND REMEDIES IN CONNECTION WITH EECI'S INDEMNITY
OBLIGATIONS UNDER SECTION 15.2, MLP, EACH OF THE COMPANY GROUP AND ALL OTHER MLP
INDEMNIFIED PERSONS WARRANT, AGREE AND COVENANT NOT TO SUE OR INSTITUTE
ARBITRATION AGAINST EECI OR ANY EECI INDEMNIFIED PERSON UPON ANY CLAIM, DEMAND
OR CAUSE OF ACTION FOR INDEMNITY AND CONTRIBUTION THAT HAVE BEEN ASSERTED OR
COULD BE ASSERTED FOR ANY ENVIRONMENTAL LIABILITIES OR ENVIRONMENTAL MATTERS.

                                 INDEMNIFICATION

       15.1 INDEMNIFICATION BY MLP. From and after the Closing, the Company
shall pay, perform, fulfill and discharge all Company Liabilities. Subject to
the limitations of Section 13.1 and Article 14, effective as of the Closing, MLP
(and the Company with respect to all Company Liabilities under clause (a) of
this Section 15.1) hereby indemnifies and holds harmless EECI, EECI's Affiliates
(other than any member of the Company Group), each of their respective past,
present and future directors, officers, employees, consultants and agents, and
each of the directors, officers, heirs, executors, successors and assigns of any
of the foregoing (collectively, the "EECI INDEMNIFIED PERSONS") from and against
(a) any and all Company Liabilities incurred by or asserted against any of the
EECI Indemnified Persons, INCLUDING ANY COMPANY LIABILITY BASED ON THE SOLE,
JOINT OR CONCURRENT NEGLIGENCE, GROSS NEGLIGENCE OR STRICT LIABILITY OF THE EECI
INDEMNIFIED PERSON OR ANY OTHER THEORY OF LIABILITY, WHETHER IN LAW (WHETHER
COMMON, CIVIL OR STATUTORY) OR EQUITY and (b) any Liability resulting from any
breach or nonfulfillment of any representation, warranty, covenant or agreement
on the part of MLP which is expressly set forth in this Agreement.

       15.2 INDEMNIFICATION BY EECI. Subject to the provisions of Section 15.4
and the limitations of Section 13.1 and Article 14, effective as of the Closing,
EECI hereby indemnifies and holds harmless MLP, each member of the Company
Group, each of their respective present and future directors, officers,
employees, consultants and agents, and each of the directors, officers, heirs,
executors, successors and assigns of any of the foregoing (collectively, the
"MLP INDEMNIFIED PERSONS") from and against (a) any Liability resulting from any
breach or nonfulfillment of any representation, warranty, covenant or agreement
on the part of EECI which is expressly set forth in this Agreement, (b) any and
all Excluded Liabilities, (c) the failure of Calpine to pay any Bamagas Firm
Capacity Payments because of the Calpine Dispute, except with respect to any
Bamagas Firm Capacity Payment for which the accounts receivable thereto was
eliminated in computing the Capitalization under Section 3.3(f) and (d) any
breach by Bamagas under the Bamagas Contracts that arises on account of the
contribution of the Company (and, indirectly, the Company Subsidiaries) to MLP
or the Restructuring Actions.

         For purposes of this Section 15.2, whether EECI has breached any of its
representations and warranties herein shall be determined without giving effect
to any qualification as to materiality, Material Adverse Effect, or concepts of
similar import.

       15.3 INDEMNIFICATION AND DEFENSE PROCEDURES. A Person that is entitled to
be indemnified under Section 5.1, 15.1 and/or 15.2 is herein referred to as an
"INDEMNIFIED PERSON" and the party that is obligated to indemnify an Indemnified
Person under Section 5.1 or 15.2 is herein referred to as the "INDEMNIFYING
PARTY" with respect to the matter for which it is obligated to indemnify such
Indemnified Person. All claims for indemnification under Sections 15.1 and 15.2
shall be asserted and resolved as follows:

              (a) If a third party claim for which an Indemnified Person is
entitled to indemnity under Sections 5.1(b), 15.1 and/or 15.2 (an "INDEMNIFIED
CLAIM") is made against an Indemnified Person, and if MLP or EECI intends to
seek indemnity with respect thereto by or from an Indemnifying Party pursuant to
Sections 5.1(b), 15.1 and/or 15.2, then the party electing to seek indemnity on
behalf of such indemnified Person shall promptly transmit to the Indemnifying
Party a written notice ("CLAIM NOTICE") (i) notifying such Indemnifying Party of
such Indemnified Claim and request indemnity on behalf of such Indemnified
Person with respect to such Indemnified Claim under Sections 5.1(b), 15.1 and/or
15.2, as the case may be, (ii) setting forth the full name, address for all
notices and the authorized representatives of such Indemnified Person with
respect to such Indemnified Claim, and (iii) describing in reasonable detail the
nature of the Indemnified Claim, including a copy of all papers served with
respect to such Indemnified Claim (if any) and the basis of such request for
indemnification under Sections 5.1(b), 15.1 and/or 15.2, as the case may be.
Failure to provide such Claim Notice promptly shall not affect the right of the
Indemnified Person to indemnification hereunder except to the extent the
Indemnifying Party is prejudiced thereby; provided that, the Indemnifying Party
shall not be obligated to defend, indemnify or otherwise hold harmless an
Indemnified Person with respect to a third party claim until a Claim Notice
meeting the foregoing requirements is furnished to the Indemnifying Party by the
party seeking indemnity hereunder. Within thirty (30) days after receipt of any
Claim Notice (the "ELECTION PERIOD"), the Indemnifying Party shall notify the
party who sent the Claim Notice (A) whether the Indemnifying Party disputes its
potential liability to indemnify the Indemnified Person under Sections 5.1(b),
15.1 and/or 15.2, as the case may be, with respect to such third party claim and
(B) whether the Indemnifying

                                       45
<Page>

Party desires to defend the Indemnified Person against such third party claim;
provided that, if the Indemnifying Party fails to so notify the Indemnified
Person during the Election Period, the Indemnifying Party shall be deemed to
have elected to dispute such liability and not to defend against such third
party claim. The aforesaid election or deemed election by the Indemnifying Party
not to assume the defense of the Indemnified Person with respect to such
Indemnified Claim, however, shall be subject to the right of the Indemnifying
Party to subsequently assume the defense of the Indemnified Person with respect
to such Indemnified Claim at any time prior to settlement or final determination
thereof.

              (b) If the Indemnifying Party notifies the party who sent the
Claim Notice within the Election Period that the Indemnifying Party (i) does not
dispute its liability to indemnify the Indemnified Person under Sections 5.1(b),
15.1 and/or 15.2, as the case may be (or reserves the right to dispute whether
such claim is an Indemnified Claim under Section 15.1 and/or 15.2) and (ii)
elects to assume the defense of such Indemnified Person with respect to such
third party claim, then the Indemnifying Party shall have the right to defend,
at its sole cost and expense, such third party claim by all appropriate
proceedings, which proceedings shall be prosecuted diligently by the
Indemnifying Party to a final conclusion or settled at the discretion of the
Indemnifying Party in accordance with this Section 15.3(b). If an Indemnifying
Party elects pursuant to the foregoing to assume the defense of an Indemnified
Person with respect to a third party claim which is subsequently determined not
to be an Indemnified Claim, then, without limiting any action the Indemnifying
Party may have on account of actual fraud, the Indemnifying Party shall not be
entitled to recover from the other party or the Indemnified Person the costs and
expenses incurred by the Indemnifying Party in providing such defense. The
Indemnifying Party shall have full control of such defense and proceedings,
including any compromise or settlement thereof; provided that the Indemnifying
Party shall not enter into any settlement agreement (or settle or compromise any
such third party claim in a manner) which provides for or results in any payment
by or Liability of the Indemnified Person of or for any damages or other amount,
any lien, charge or encumbrance on any property of the Indemnified Person, any
finding of responsibility or liability on the part of the Indemnified Person or
any sanction or restriction upon the conduct of any business by the indemnified
Person without the Indemnified Person's express written consent, which consent
shall not be unreasonably withheld. The Indemnified Person is hereby authorized,
at the sole cost and expense of the Indemnifying Party (but only if the
Indemnified Person is actually entitled to indemnification hereunder), to file,
during the Election Period, any motion, answer or other pleadings which the
Indemnified Person shall deem necessary or appropriate to protect its interests
or those of the Indemnifying Party and not reasonably expected to be prejudicial
to the Indemnifying Party. If requested by the Indemnifying Party, the
Indemnified Person agrees, at the sole cost and expense of the Indemnifying
Party, to cooperate with the Indemnifying Party and its counsel in contesting
any such third party claim which the Indemnifying Party elects to contest,
including the making of any related counterclaim or cross-complaint against any
Person (other than an MLP Indemnified Person, if the Indemnified Person is an
MLP Indemnified Person, or an EECI Indemnified Person, if the Indemnified Person
is an EECI Indemnified Person). The Indemnified Person may participate in, but
not control, any defense or settlement of any third party claim controlled by
the Indemnifying Party pursuant to this Section 15.3(b), and the Indemnified
Person shall bear its own costs and expenses with respect to such participation.
The prosecution of the defense of a third party claim with reasonable diligence
shall include the taking of such action (including the posting of a bond,
deposit or other security) as may be necessary to prevent any action to

                                       46
<Page>

foreclose a lien against or attachment of the property of the Indemnified Person
for payment of such third party claim.

              (c) If the Indemnifying Party (i) fails to notify the party who
sent the Claim Notice within the Election Period that the Indemnifying Party
elects to defend the Indemnified Person pursuant to Section 15.3(b) or (ii)
elects to defend the Indemnified Person pursuant to Section 15.3(b) but fails to
prosecute the defense of (or to settle) the third party claim with reasonable
diligence, then the Indemnified Person shall have the right to defend, at the
sole cost and expense of the Indemnifying Party (but only if the Indemnified
Person is actually entitled to indemnification hereunder), the third party claim
by all appropriate proceedings, which proceedings shall be promptly and
vigorously prosecuted by the Indemnified Person to a final conclusion or
settled. Unless and until such defense is assumed by the Indemnifying Party as
permitted in Section 15.3(a), the Indemnified Person shall have full control of
such defense and proceedings; provided, however, that the Indemnifying Party,
without assuming the defense of such Indemnified Claim, may participate in, but
not control, any defense or settlement controlled by the Indemnified Person
pursuant to this Section 15.3(c), and the Indemnifying Party shall bear its own
costs and expenses with respect to such participation. The Indemnified Person
may not enter into any compromise or settlement of such third party claim,
without the Indemnifying Party's express written consent, which shall not be
unreasonably withheld.

              (d) If an Indemnified Person is entitled to indemnity under
Sections 5.1(b), 15.1 and/or 15.2 for a claim or other matter which does not
involve a third party claim, and if MLP or EECI intends to seek indemnity on
behalf of an Indemnified Person with respect thereto by or from an Indemnifying
Party pursuant to Sections 5.1(b), 15.1 and/or 15.2, then the party electing to
seek indemnity on behalf of an Indemnified Person shall promptly transmit to the
Indemnifying Party a written notice describing in reasonable detail the nature
of such claim or other matter, the Indemnified Person's best estimate of the
amount of damages attributable to such claim or other matter and the basis for
the Indemnified Person's entitlement to indemnification under Sections 5.1(b),
15.1 and/or 15.2, as the case may be. If the Indemnifying Party does not notify
the party who sent such notice within thirty (30) days from its receipt of such
notice that the Indemnifying Party does not dispute such claim for indemnity,
the Indemnifying Party shall be deemed to have disputed such claim.

              (e) To the extent any claim, action, suit or proceeding includes
one or more Indemnified Claims with respect to an Indemnified Person and one or
more third party claims which are not Indemnified Claims with respect to such
Indemnified Person, any such non-Indemnified Claim insofar as it is with respect
to such Indemnified Person shall not be covered by the indemnity in Sections
15.1 and 15.2, the Indemnifying Party shall not be obligated to undertake,
conduct and control the defense or settlement of such non-Indemnified Claim
insofar as it is with respect to such Indemnified Person, and such Indemnified
Person shall be responsible for its own defense and settlement of such
non-Indemnified Claim. The seeking by a party of indemnity hereunder on behalf
of any Indemnified Person with respect to any third party claim or other claim
or matter shall not prevent such party from then or thereafter also seeking
indemnity hereunder on behalf of any other Indemnified Person with respect to
such third party claim or other claim or matter and shall not prevent the other
party from seeking indemnity hereunder on behalf of any Indemnified Person with
respect to the same third party claim or other claim or matter.

       15.4   LIABILITY LIMITATIONS.

              (a) Notwithstanding anything herein provided to the contrary, EECI
shall have no Liability to MLP or any other MLP Indemnified Person pursuant to
Sections 15.2(a) or for any breach by EECI of this Agreement, except with
respect to Liabilities arising by virtue of any breach by EECI of its
representations and warranties under Section 4.1(e) and 4.1(r) and Liabilities
arising under any of Sections 9.5, 9.6, 9.15, 15.2(b), 15.2(c), 15.2(d) or
Article 10, unless and until the aggregate amount of all Liabilities covered by
Section 15.2, exceeds the sum of $20,000,000. EECI shall be liable in accordance
with the other terms of this Agreement for those Liabilities in excess of
$20,000,000 subject to the further provisions of this Section 15.4. EECI shall
be liable for all Liabilities arising by virtue of any breach by EECI of its
representations and warranties under Sections 4.1(e) and 4.1(r) and for all
Liabilities arising under Sections 9.5, 9.6, 9.15, 15.2(b), 15.2(c), 15.2(d) and
Article 10.

              (b) Notwithstanding anything herein provided to the contrary,
except as hereinafter provided in this Section 15.4(b), the maximum aggregate
Liability of EECI to MLP and the other MLP Indemnified Persons pursuant to
Section 15.2(a) (other than with respect to Sections 4.1(e) and 4.1(r)) shall be
limited to $150,000,000. EECI's Liability for its indemnification pursuant to
Section 15.2(a) with respect to any breach by EECI of its representation and
warranty under Sections 4.1(e) and 4.1(r) or with respect to any breach by EECI
of any of its covenants and agreements under Sections 9.5, 9.6, 9.15, 15.2(b),
15.2(c), 15.2(d) or Article 10 shall not be limited under this Agreement.

              (c) The Liabilities or other adverse consequences giving rise to
any indemnification obligation hereunder shall be limited to the actual loss
suffered by the Indemnified Person (that is, reduced by any insurance payment or
recoupment received, realized or retained by the Indemnified Person as a result
of the events giving rise to the claim for indemnification, net of any expenses
related to the receipt or collection of such proceeds, payment or recoupment,
including premium adjustments, if any), but not any reduction in Taxes of the
Indemnified Person (or the affiliated group of which it is a member) occasioned
by such Liabilities or other adverse consequences.

              (d) EECI, MLP, the Company Group and each other Indemnified Person
shall cooperate with the Indemnifying Party with respect to resolving any
Indemnified Claim with respect to which either EECI or MLP is obligated to
indemnify an Indemnified Person under this Article 15, including making
commercially reasonable efforts to mitigate or resolve any such Indemnified
Claim and providing the others with reasonable access to such Indemnified
Person's records (other than those subject to attorney-client or attorney work
product privilege) and personnel having relevant information with respect to the
Indemnified Claim. Without limiting the foregoing, to the extent it may legally
do so each party agrees to assign or cause the assignment to the Indemnifying
Party with respect to an Indemnified Claim any and all of the rights and
remedies that the Indemnified Person may have with respect to such Indemnified
Claim against any Person (other than EECI, MLP, any member of the Company Group
or any Affiliate of EECI, MLP or any member of the Company Group or any
insurance carrier or bonding or surety company of the Indemnified Person)
pursuant to any claims, rights and agreements of or for indemnification,
guarantee, contribution, reimbursement or similar assurances which are the
subject of such Indemnified Claim.

              (e) Each party agrees to maintain all records and information made
available to it pursuant to Section 15.4(d) confidential and to cause its
directors, officers, employees, agents, representatives, consultants and
advisors to maintain all records and information made available to them pursuant
to this Section confidential, except (i) as required by Law, administrative
process or any standards or rules of any stock exchange to which such party or
any of its Affiliates is subject, (ii) for information which is available to the
public on the date hereof, or thereafter becomes available to the public other
than as a result of a breach of this Section 15.4(e), and (iii) to the extent
that such party must disclose the same in any court or arbitration proceedings
brought by it to enforce its rights hereunder.

       15.5 COVENANT REGARDING ACTIONS OF EECI REGARDING ITS ASSETS. For so long
as EECI has an indemnification obligation pursuant to Section 15.2(a), 15.2(c)
or 15.2(d), it will not make any dividend or distribution on its stock, or
repurchase any shares of its stock, or sell or otherwise dispose of any assets
or take any other action within its control if the effect of such action would
cause its net worth (excluding accumulated other comprehensive income), as
calculated under GAAP on a consolidated basis, to be less than $290,000,000.

       15.6 EXCLUSIVE REMEDY. After Closing, absent actual fraud, the indemnity
provisions of this Article 15 shall be the sole and exclusive remedy of each
party for or on account of any breach by the other party of any of such other
party's representations and warranties under this Agreement. THE PARTIES
ACKNOWLEDGE AND AGREE THAT, ABSENT ACTUAL FRAUD, THE REMEDIES SET FORTH IN THIS
AGREEMENT, INCLUDING THE DEDUCTIBLES, LIABILITY LIMITS, SURVIVAL PERIODS,
DISCLAIMERS AND LIMITATIONS ON REMEDIES, ARE INTENDED TO BE, AND SHALL BE, THE
EXCLUSIVE REMEDIES WITH RESPECT TO ANY ASPECT OF THE TRANSACTIONS CONTEMPLATED
BY THIS AGREEMENT. EXCEPT WITH RESPECT TO CAUSES OF ACTION OR CLAIMS FOR ACTUAL
FRAUD, EACH PARTY HEREBY RELEASES, WAIVES AND DISCHARGES, AND COVENANTS NOT TO
SUE WITH RESPECT TO, ANY CAUSE OF ACTION OR CLAIM NOT EXPRESSLY PROVIDED FOR IN
THIS AGREEMENT INCLUDING, WITHOUT LIMITATION, CLAIMS UNDER STATE OR FEDERAL
SECURITIES LAWS AND CLAIMS, AVAILABLE AT COMMON LAW OR BY STATUTE.

       16.1   TERMINATION.

              (a)    TERMINATION OF AGREEMENT. This Agreement and the
transactions contemplated hereby may be terminated at any time prior to the
Closing:

                     (1)    by the mutual consent of EECI and MLP;

                     (2)    if the Closing has not occurred by the close of
business on October 31, 2002, then (i) by EECI if any condition specified in
Section 11.1 has not been satisfied on or before such close of business, and
shall not theretofore have been waived by EECI, or (ii) by MLP if any condition
specified in Section 11.2 has not been satisfied on or

                                       49
<Page>

before such close of business, and shall not theretofore have been waived by
MLP; provided, in each case, that the failure to consummate the transactions
contemplated hereby on or before such date did not result from the failure by
the party or parties seeking termination of this Agreement to fulfill any
undertaking or commitment provided for herein on the part of such party or
parties that is required to be fulfilled on or prior to Closing;

                     (3)    by MLP, if a material default shall have been made
in the observance or performance by EECI or the Company of any agreements and
covenants of EECI or the Company contained herein, or if there shall have been a
material breach by EECI or the Company of any representations or warranties
contained herein and, in each case, such default or breach is not cured within
thirty (30) days after receipt by EECI or the Company of written notice from MLP
of such default or breach;

                     (4)    by EECI, if a material default shall have been made
in the observance or performance by MLP of any agreements and covenants of MLP
contained herein, or if there shall have been a material breach by MLP of any
representations or warranties contained herein and, in each case, such default
or breach is not cured within thirty (30) days after receipt by MLP of written
notice from EECI of such default or breach;

                     (5)    by either party, if there shall be any order, writ,
injunction or decree of any Governmental Authority binding EECI, the Company or
MLP that prohibits or restrains EECI, the Company or MLP from consummating the
transactions contemplated hereby; or

                     (6)    by either party pursuant to Section 9.6

              (b) EFFECT OF TERMINATION. In the event of termination of this
Agreement by EECI, on the one hand, or MLP, on the other hand, pursuant to
Section 16.1(a), written notice thereof shall forthwith be given by the
terminating party or parties to the other party or parties hereto, and this
Agreement shall thereupon terminate; provided, however, that following such
termination MLP will continue to be bound by its obligations set forth in
Sections 5.1(b)(ii) and 5.2. If this Agreement is terminated as provided herein
all filings, applications and other submissions made to any Governmental
Authority shall, to the extent practicable, be withdrawn from the Governmental
Authority to which they were made.

       16.2 EXCLUSIVE REMEDY. Prior to Closing, the remedy of termination
provided in Section 16.1 shall be each party's sole and exclusive remedy for any
breach or default by the other party of this Agreement, all other remedies being
expressly waived.

                                   ARTICLE 17
                                  MISCELLANEOUS

HEREBY SHALL BE GOVERNED BY AND INTERPRETED IN

                                       50

ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS WITHOUT GIVING EFFECT TO
PRINCIPLES THEREOF RELATING TO CONFLICTS OF LAW RULES THAT WOULD DIRECT THE
APPLICATION OF THE LAWS OF ANOTHER JURISDICTION; PROVIDED, HOWEVER, THAT MATTERS

WITH THE LAWS OF THE JURISDICTION WHERE SUCH ASSETS ARE LOCATED.

       17.3 ENTIRE AGREEMENT. This Agreement and the Appendices, Schedules and

inure to the benefit of the parties hereto and their respective successors and

       17.7 AMENDMENTS AND WAIVERS. This Agreement may not be modified or
amended except by an instrument or instruments in writing signed by the party
against whom enforcement of any such modification or amendment is sought. Any
party hereto may, only by an instrument in writing, waive compliance by another
party hereto with any term or provision of this Agreement on the part of such
other party hereto to be performed or complied with. The waiver by any party
hereto of a breach of any term or provision of this Agreement shall not be
construed as a waiver of any subsequent breach.

       17.8   APPENDICES, SCHEDULES AND EXHIBITS. All Appendices, Schedules and
Exhibits hereto which are referred to herein are hereby made a part hereof and
incorporated herein by such reference.

       17.9 INTERPRETATION. It is expressly agreed that this Agreement shall not
be construed against any party, and no consideration shall be given or
presumption made, on the basis of who drafted this Agreement or any particular
provision hereof or who supplied the form of Agreement. Each party agrees that
this Agreement has been purposefully drawn and correctly reflects its
understanding of the transaction that this Agreement contemplates. In construing
this Agreement:

              (a)    examples shall not be construed to limit, expressly or by
implication, the matter they illustrate;

              (b)    the word "includes" and its derivatives mean "includes, but
is not limited to" and corresponding derivative expressions;

              (c) a defined term has its defined meaning throughout this
Agreement and each Appendix, Exhibit and Schedule to this Agreement, regardless
of whether it appears before or after the place where it is defined;

              (d) each Exhibit and Schedule is a part of this Agreement, but if
there is any conflict or inconsistency between the main body of this Agreement
(including Appendix A, which shall be considered part of the main body of this
Agreement) and any Exhibit or Schedule, the provisions of the main body of this
Agreement shall prevail;

              (e)    the headings and titles herein are for convenience only and
shall have no significance in the interpretation hereof;

              (f) the inclusion of a matter on a Schedule in relation to a
representation or warranty shall not be deemed an indication that such matter
necessarily would, or may, breach such representation or warranty absent its
inclusion on such Schedule; and

              (g)    references to "dollars" or "$" shall mean the lawful
currency of the United States.

       17.10  ARBITRATION.

              (a) Except as provided in Section 3.3, it is agreed, as a
severable and independent arbitration agreement separately enforceable from the
remainder of this Agreement,

                                       53
<Page>

that if the parties hereto, the Company, the Indemnified Persons or their
respective successors, assigns, heirs or legal representatives of any of the
foregoing are unable to amicably resolve any dispute or difference arising under
or out of, in relation to or in any way connected with this Agreement (whether
contractual, tortuous, equitable, statutory or otherwise), such matter shall be
finally and exclusively referred to and settled by arbitration under the
Commercial Arbitration Rules of the American Arbitration Association ("AAA");
provided that, the foregoing shall not prevent EECI, the Company or their
Affiliates from seeking specific performance, an injunction or other equitable
relief with respect to their rights under Section 5.2 through judicial means in
any jurisdiction. In the event of any conflict between the Commercial
Arbitration Rules of the AAA and the provisions of this Section 17.10, the
provisions of this Section 17.10 shall govern and control.

              (b) The arbitration shall be heard and determined by three (3)
arbitrators. Each side shall appoint an arbitrator of its choice within fifteen
(15) days of the submission of a notice of arbitration. The party-appointed
arbitrators shall in turn appoint a presiding arbitrator of the tribunal within
fifteen (15) days following the appointment of both party-appointed arbitrators.
If the party-appointed arbitrators cannot reach agreement on a presiding
arbitrator of the tribunal and/or one party fails or refuses to appoint its
party-appointed arbitrator within the prescribed period, the appointing
authority for the presiding arbitrator and/or such party-appointed arbitrator
shall be the AAA, who, in each case, shall appoint an independent arbitrator who
does not have any financial interest in the dispute, controversy or claim or any
bear relationship to either party. If an arbitrator should die, withdraw or
otherwise become incapable of serving, or refuse to serve, a successor
arbitrator shall be selected and appointed in the same manner as the original
arbitrator.

              (c)    Unless otherwise expressly agreed in writing by the parties
to the arbitration proceedings:

                     (1)    The arbitration proceedings shall be held in
Houston, Texas;

                     (2)    The arbitration proceedings shall be conducted in
the English language and the arbitrator(s) shall be fluent in the English
language;

                     (3)    The arbitrators shall be and remain at all times
wholly independent and impartial;

                     (4)    The arbitration proceedings shall be conducted under
the Commercial Arbitration Rules of the AAA, as amended from time to time;

                     (5)    Any procedural issues not determined under the
arbitration rules selected pursuant to Section 17.10(c)(4) shall be determined
by the arbitration act and any other applicable laws of the State of Texas,
other than those laws which would refer the matter to another jurisdiction;

                     (6)    All decisions and awards by the arbitration tribunal
shall be made by majority vote;

                                       54
<Page>

                     (7)    The decision of a majority of the arbitrators shall
be reduced to writing; shall be final and binding without the right of appeal;
and shall be the sole and exclusive remedy regarding any claims, counterclaims,
issues or accountings presented to the arbitrators; any damage awards by the
arbitrators shall be stated in dollars, and promptly paid in dollars free of any
deduction or offset; and any costs or fees incident to enforcing the award shall
to the maximum extent permitted by law be charged against the party resisting
such enforcement;

                      (1)   IN GENERAL.  Upon the occurrence of an
                Indemnifiable Event, Enbridge shall become obligated, in
                accordance with the terms of this Agreement, to the extent
                Management does not have sufficient cash to pay the additional
                Taxes, to pay as an indemnity such amounts as, on an After-Tax
                Basis, shall be equal to the amount of the additional Taxes
                incurred by Management as a result of such Indemnifiable Event
                (the "Indemnity Amount"). In addition, the Indemnity Amount
                shall be increased, on an After-Tax Basis, by the amount of
                all reasonable out-of-pocket expenses incurred by Management
                that would not otherwise have been incurred by Management, and

                Management as result of: (i) any Indemnifiable Event or (ii)
                any determination by Management of the existence or amount of

                be increased by an amount equal to interest accrued at the

                actually been paid to the IRS or other applicable taxing
                authority by Management from the assumed date of payment of
                such Taxes (as provided in Section 4(b)), provided that (x) a
                payment of Taxes in respect of which Enbridge has advanced
                funds to Management pursuant to Section 5(d) shall not accrue
                interest and (y) such interest shall cease to accrue if the
                payment date of the Indemnity Amount is delayed as a result of
                the failure of Management to

                                       6

<Page>

                provide notice and computations to Enbridge within a reasonable
                time pursuant to Section 3(b).

                      (3)   REIMBURSEMENT FOR REALIZED TAX SAVINGS.  To the
                extent that any Indemnity Amount is paid pursuant to this
                Section 3 in respect of an Indemnifiable Event, Management
                shall reimburse Enbridge for any Tax savings (i) which are
                realized and which Management would not have realized but for
                such Indemnifiable Event and (ii) which are actually received
                or recognized by Management in the form of cash or a cash
                savings at a time when such cash or cash savings is not
                otherwise required by Management to pay its legal obligations,
                including, without limitation, its Taxes, and excluding the
                obligation created by this Section 3(a)(3) ("Realized Tax
                Savings").  Management shall pay any Realized Tax Savings
                within 15 days of the earlier of (i) Management determining
                that such Realized Tax Savings exist or (ii) any final
                determination, pursuant to Section 6, that any such Realized
                Tax Savings exist and are available for payment pursuant to
                this Section 3(a)(3). Notwithstanding the foregoing,
                Management shall not be required to make any payment pursuant
                to this Section 3(a)(3) to the extent that the amount of such
                payment would exceed (i) the amount of all prior payments by
                Enbridge to Management pursuant to Section 3(a)(1) with
                respect to the Indemnifiable Event which gave rise to the
                Realized Tax Savings, less (ii) the amount of all prior
                payments by Management pursuant to this Section 3(a)(3) with
                respect to such Indemnifiable Event. If for any reason any
                Realized Tax Savings paid to Enbridge pursuant to this Section
                3(a)(3) or taken into account in computing the amount of any
                indemnity payable hereunder pursuant to Section 3(a)(1) shall,
                as a result of a Final Determination or otherwise, be
                unavailable, such unavailability shall be treated as an
                Indemnifiable Event subject to indemnification by Enbridge
                pursuant to Section 3(a)(1), above.

                (b)   DATE FOR PAYMENT.  The amount payable by Enbridge
         pursuant to Section 3(a) shall be paid upon the occurrence of the
         latest of:

                      (1)   subject to Section 6 and the next sentence, 15
                Business Days after the receipt by Enbridge of a notice from
                Management accompanied by its computations in accordance with
                Section 6;

                      (2)   if any such indemnity payment relates to an
                Indemnifiable Event that is contested pursuant to Section 5,
                15 Business Days after the date of a Final Determination with
                respect to such Indemnifiable Event; and

                      (3)   in the case of, and to the extent such amount
                payable by Enbridge pursuant to Section 3(a) relates to, the
                redemption or other disposition of the MLP I-Units, and
                subject to Section 6 and the next sentence, 15 Business Days
                after the redemption or other disposition of the MLP I-Units.

The date required for payment pursuant to the preceding sentence shall be
delayed until 15 Business Days after delivery to Enbridge of any verification
requested pursuant to Section 6.

         4.     COMPUTATIONAL ASSUMPTIONS.

                (a)   IN GENERAL.  For purposes of (i) computing the amount of
         Taxes payable as a result of an Indemnifiable Event and (ii) the

         statutory rate generally applicable to corporations for the relevant
         period or periods, and to the extent Management is subject to state
         and local income Taxes it shall be assumed to be subject to state and

         the IRS or other applicable taxing authority. Realized Tax Savings
         pursuant to Section 3(a)(3) will be assumed to be realized on the

         required to indemnify Management hereunder, Management hereby agrees
         promptly to notify Enbridge in writing of such claim (but a failure
         to do so will not diminish Enbridge's obligations under this
         Agreement except to the extent that (i) Enbridge is harmed by such
         failure and (ii) at the time such notification should have been
         provided, either (A) Enbridge and its Affiliates collectively were
         not the Record Holders of a majority of the Voting Shares then

         Directors of Management consisted of independent directors as
         required by the principal National Securities Exchange on which
         Listed Shares were listed or admitted to trading, the Securities and
         Exchange Commission or applicable Law); PROVIDED, HOWEVER, that if
         EECI receives any such notice as the tax matters partner of the MLP,
         Enbridge shall be deemed to have received notice under this Section
         5(a).

                (b)   AGREEMENT TO CONTEST.  Subject to Section 5(d) and
         provided the conditions set forth in Section 5(c) are satisfied, (i)
         Management agrees to contest (or join in contesting) in good faith
         such claim and agrees not to settle such claim without the written
         approval of Enbridge, (ii) subject to clause (iii) of this Section
         5(b), the conduct of the contest shall be controlled by Management

         (iii) Enbridge shall have the right, upon its election in writing to
         Management and at its sole expense, to control the contest of such
         claim (including the defense, prosecution, settlement or compromise
         thereof), and Management shall take such action in connection with
         contesting such claim as Enbridge shall reasonably request in writing

                                       8

                Management a written opinion of independent, nationally-
                recognized tax counsel selected by Enbridge (such counsel and
                form of opinion to be reasonably satisfactory to Management) to
                the effect that there is a Reasonable Basis for contesting such
                action or proposed action by the IRS or other taxing authority;

                      (2)   Enbridge shall have agreed to pay, on an After-Tax

                (including reasonable attorneys fees of legal counsel
                reasonably selected by Management or Enbridge, as applicable)
                that Management shall incur in connection with contesting such
                action or proposed action; and

                      (3)   the amount of the indemnity that would be payable
                hereunder (which shall include prospective exposure in future
                tax years attributable to the position being challenged) shall
                exceed U.S. $5,000.

                (d)   REFUND CLAIMS.  If Management or Enbridge, as
         applicable, shall determine in its reasonable discretion that
         Management shall pay the Tax claimed and sue for a refund, Enbridge
         must either, at its option and to the extent necessary for the
         contest to proceed, (i) promptly advance to Management on an
         interest-free basis sufficient funds to pay the Tax payable with
         respect thereto or (ii) pay to Management the amount payable pursuant
         to Section 3 (but without regard to the time of payment in Section
         3(b)) with respect to such claim.

                (e)   TIME AT WHICH OBLIGATIONS OPERATIVE.  In any
         circumstance where judicial review shall be unavailable, Enbridge's
         right to cause a contest hereunder, and Management's obligation to
         contest hereunder, shall become operative at the earliest time such a
         contest may, pursuant to law, be initiated, provided that Enbridge
         has then satisfied all of the necessary preconditions to the exercise
         of its contest rights.

                (f)   DEFERRAL OF INDEMNIFICATION.  If Enbridge shall have
         requested Management to contest such claim as above provided and
         shall have duly complied and remains in compliance with all the terms
         of this Section 5, Enbridge's liability for indemnification shall be
         deferred (as provided in Section 3) until a Final Determination of
         the liability of Management. At such time, Enbridge shall become
         obligated for the payment of any indemnification hereunder resulting
         from the outcome of such contest, and, to the extent funds were
         advanced by Enbridge pursuant to Section 5(d), Management shall
         become obligated to refund to Enbridge any amount received as a
         refund by Management or credited to Management and fairly
         attributable to advances by

                                       9

<Page>

         Enbridge, net of any Taxes attributable to the receipt of such refund
         or credit. Within 15 Business Days following such Final Determination,
         any amounts due hereunder shall be paid first by set off against each
         other and then either:

                      (1)   Enbridge shall pay to Management any excess of the
                full amount due hereunder over the amount of any advances
                previously made by Enbridge and applied against its indemnity
                obligation as aforesaid; or

                      (2)   Management shall repay to Enbridge any excess of
                such advances, net of any Taxes attributable to Management's
                receipt of such refund or credit, over such full amount due
                hereunder, together with any interest received from the IRS or
                other taxing authority by Management that is properly
                attributable to such advances during the period such advances
                were outstanding and that is in excess of the amount of any
                Taxes attributable to Management's receipt or accrual of such
                interest.

                (g)   RECORDS AND PARTICIPATION.

                      (1)   INDEMNIFIED PARTY.  Management shall provide
                Enbridge with all documents and information related to the
                contest as may be reasonably requested by Enbridge, shall keep
                Enbridge fully informed, shall afford Enbridge the opportunity
                to attend and participate in any meetings or negotiations with
                the IRS or other taxing authority regarding such contest and
                shall otherwise fully cooperate with Enbridge in good faith in
                connection with such contest.  Management will consult in good
                faith with (and, in the event that Enbridge has not exercised
                its contest control rights under Section 5(b)(iii), consider
                in good faith suggestions by) Enbridge and its counsel
                regarding relevant aspects of the progress and nature of any
                such contest, provided that nothing in this Agreement shall
                require Management to provide Enbridge with proprietary
                information relating to the identity of Management's
                shareholders, owners, members or lenders.

                      (2)   ENBRIDGE.  Within a reasonable time under the
                circumstances after reasonable written request therefor from
                Management, Enbridge shall provide such information and copies
                of records as are within its control to enable Management to
                fulfill its Tax return filing, audit and litigation
                obligations in connection with the transactions contemplated
                by the Management L.L.C. Agreement, provided that nothing in
                this Agreement shall require Enbridge to provide Management
                with its Tax returns.

         6.     VERIFICATION.  The results of all computations to be made with
respect to Management under this Agreement, together with a statement
describing in reasonable detail the manner in which such computations were
made, shall be delivered to Enbridge in writing. Preparation and delivery of
such computations shall be pursued diligently, in a timely manner and in good
faith, and notice of an Indemnifiable Event and delivery of such computations
to Enbridge shall be made within a reasonable time under the circumstances. If
Enbridge so requests within 10 Business Days after receipt of such
computations, any determination shall be

                                      10

<Page>

reviewed by the independent accounting firm who regularly audits Management,
who shall be asked to verify, after consulting with Enbridge and Management,
whether Management's computations are correct, and to report its conclusions
(within 20 Business Days upon being requested to verify and determine the
correct computation) to both Enbridge and Management. Enbridge also may request
that such accounting firm review Management's Tax returns for any year to
determine if Management is required to make any payment pursuant to Section
3(a)(3). Management and Enbridge hereby agree to provide such accountants with
all information and materials as shall be reasonably necessary or desirable in
connection herewith. Any information provided to such accountants by any person
shall be and remain the exclusive property of such person and shall be deemed
by the parties to be (and the accountants shall confirm in writing that they
shall treat such information as) the private, proprietary and confidential
property of such person, and no person other than such person and the
accountants shall be entitled thereto, and all such materials shall be returned
to such person. The reasonable fees and expenses of the accountants in
verifying an amount pursuant to this Agreement shall be paid by Enbridge;
provided, that Management and not Enbridge shall be required to pay such fees
if the computations provided by Management were not prepared in good faith. The
parties hereto agree that the sole responsibility of the accountants hereunder
shall be to verify calculations hereunder and that all matters of
interpretation of this Agreement shall not be within the scope of the
accountant's responsibilities.

    7.  EXTENSION AND ADJUSTMENT OF AGREEMENT IN THE CASE OF MANAGEMENT
SUBSIDIARIES.  To the extent that Management forms one or more Management
Subsidiaries to perform any activities or hold any assets (including I-Units)
which Management is permitted under the Management L.L.C. Agreement to perform
or hold directly, (i) the indemnity and other provisions of this Agreement
shall be automatically extended to include and take into account, in addition
to Management, any such Management Subsidiary, (ii) to the extent such
Management Subsidiary is recognized as an entity separate from Management for
the applicable Tax purpose, the Management Subsidiary shall be indemnified by
Enbridge to the same extent that Management would have been indemnified had it
performed such activities (and received any related reimbursements or payments)
or held such assets directly, and (iii) correlative adjustments to the terms
and definitions of this Agreement and their application shall be made, to the
extent appropriate to the context, to take into account the legal existence of
such Management Subsidiary, the actual ownership of assets and/or performance
of activities by the Management Subsidiary and the applicable tax status of the
Management Subsidiary (E.G., as a disregarded or recognized entity for the
applicable Tax purpose) and to avoid any duplication of payments made pursuant
to this Agreement.

    8.  LATE PAYMENTS.  Except as otherwise provided in this Agreement, any
amount payable to Management or Enbridge under this Agreement not paid when due
shall bear interest from the date due to the date paid at the Interest Rate.

    9.  NO DUPLICATION OF PAYMENTS.  Nothing contained in this Agreement shall
be construed to permit Management to receive payment with respect to an
Indemnifiable Event hereunder more than once, to permit Management to receive
payment with respect to an Indemnifiable Event in duplication of any payment
with respect to such Indemnifiable Event previously received by any transferor
of Management's interest, to permit any third-party

                                      11
<Page>

beneficiary hereof to recover any amount hereunder or to require Management to
pay any Realized Tax Savings arising out of any Indemnifiable Event more than
once.

    10.  NOTICES.  All notices and other communications shall be given in the
manner, to the respective addresses, and shall become effective as provided in
the Management L.L.C. Agreement except to the extent otherwise expressly
provided herein, except that notices or communications shall be directed to

    11.  ASSIGNMENT.  The obligations and liabilities of Enbridge and
Management arising under this Agreement are expressly made for the benefit of,
and shall be enforceable by, Management and Enbridge and their respective
successors and permitted assigns.  It is expressly provided that Enbridge may
assign to Enbridge (U.S.) Inc. or any other Affiliate of Enbridge, and such
assignee may assume, Enbridge's obligations, rights and/or liabilities under
this Agreement.  Any assignment by Enbridge of any of its obligations or
liabilities hereunder will not relieve Enbridge of any such obligations or
liabilities without the consent of Management.

    12.  SURVIVAL.

         (a) The obligations, rights and liabilities of Enbridge and Management
    hereunder shall continue in full force and effect (notwithstanding the
    cancellation, sale, exchange, redemption or other disposition of Listed
    Shares, or the dissolution, liquidation or termination of Management, the

         Management consummates a merger with or into the MLP or a subsidiary of
         the MLP pursuant to Section 7.03 of the Management L.L.C. Agreement,
         this Agreement shall terminate immediately following the effective time
         of such merger and the obligations, rights and liabilities of Enbridge
         and Management hereunder shall not continue in force or effect as of
         that time, PROVIDED, HOWEVER, that any obligations, rights and
         liabilities of Enbridge and Management arising with respect to periods
         ending on or before the effective time of such merger shall not
         terminate and shall continue in full force and effect as provided in
         Section 12(a);

               (ii)  if a Special Event that is not a Mandatory Purchase Event
         occurs or the general partner of the MLP is removed by the limited
         partners of the MLP, this Agreement shall terminate immediately prior
         to the occurrence of such Special Event or upon such removal and the
         obligations, rights and liabilities of

                                      12
<Page>

         Enbridge and Management hereunder shall not continue in force or
         effect as of that time, PROVIDED, HOWEVER, that any obligations,
         rights and liabilities of Enbridge and Management arising with respect
         to periods before that time shall not terminate and shall continue in
         full force and effect as provided in Section 12(a); and

               (iii)  if Management is dissolved or liquidated pursuant to
         Section 7.01(a)(iii) of the Management L.L.C. Agreement, this
         Agreement shall terminate immediately prior to the Dissolution Event
         associated with such dissolution or liquidation and the obligations,
         rights and liabilities of Enbridge and Management shall not continue
         in force or effect as of that time, PROVIDED, HOWEVER, that any
         obligations, rights and liabilities of Enbridge and Management arising
         with respect to periods before that time shall not terminate and shall
         continue in full force and effect as provided in Section 12(a).

BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK,
APPLICABLE TO CONTRACTS MADE AND PERFORMED IN SUCH STATE AND WITHOUT REGARD TO
ANY CONFLICT OF LAW PROVISIONS.

    15.  COUNTERPARTS.  This Agreement may be executed in any number of
counterparts, each of which so executed shall be deemed to be an original, and
such counterparts together shall constitute and be one and the same instrument.

    16.  MISCELLANEOUS.

         (a) SEVERABILITY.  Any provision of this Agreement which is prohibited
    or unenforceable in any jurisdiction shall, as to such jurisdiction, be
    ineffective to the extent of such prohibition or unenforceability without
    invalidating the remaining provisions hereof, and any such prohibition or
    unenforceability in any jurisdiction shall not invalidate or render
    unenforceable such provision in any other jurisdiction, unless the
    provisions declared prohibited as unenforceable are essential to effectuate
    the intent of the parties with respect to the Agreement taken as a whole.
    To the extent permitted by applicable Law, each of the parties hereto
    hereby agrees that any provision hereof that renders any other term or
    provision hereof invalid or unenforceable in any respect shall be modified,
    but only to the extent necessary to avoid rendering such other term or
    provision invalid or unenforceable, and such modification shall be
    accomplished in a manner that most nearly preserves the benefit of the
    parties' bargains hereunder.

         (b) AMENDMENTS.  Neither this Agreement nor any of the terms hereof may
    be terminated, amended, supplemented, waived or modified orally, but only
    by an

                                      13
<Page>

    instrument in writing signed by the party against which the enforcement of
    the termination, amendment, supplement, waiver or modification is sought.

         (c) HEADINGS.  The section and paragraph headings in this Agreement
    are for convenience of reference only and shall not modify, define, expand
    or limit any of the terms or provisions hereof.
