the Limited Partners for the debts and obligations of the New Entity shall
not, unless such Limited Partners take part in the control of the business of
the New Entity, exceed that which otherwise had been applicable to such
Limited Partners as limited partners of the Partnership under the Delaware
Act.

      pursuant to Section 5.1.

            (b) For purposes of computing the amount of any item of income,
      gain, loss or deduction to be reflected in the Partners' Capital Accounts,
      the determination, recognition and classification of any such item shall
      be the same as its determination, recognition and classification for
      federal income tax purposes (including, without limitation, any method of
      depreciation, cost recovery or amortization used for that purpose),
      provided, that:

                  (i) Solely for purposes of this Section 4.6, the Partnership
            shall be treated as owning directly its proportionate share (as
            determined by the General Partner based upon the provisions of any
            Operating Subsidiary Agreement) of all property owned by any
            Operating Subsidiary that is not treated as a corporation for
            federal income tax purposes.

                  (ii) All fees and other expenses incurred by the Partnership
            to promote the sale of (or to sell) a Partnership Interest that can
            neither be deducted nor amortized under Section 709 of the Code, if
            any, shall, for purposes of Capital Account maintenance, be treated
            as an item of deduction at the time such fees and other expenses are
            incurred and shall be allocated among the Partners pursuant to
            Section 5.1.

                  (iii) Except as otherwise provided in Treasury Regulation
            Section 1.704-1(b)(2)(iv)(m), the computation of all items of
            income, gain, loss and deduction shall be made without regard to any
            election under Section 754 of the Code which may be made by the
            Partnership and, as to those items described in Section 705(a)(1)(B)
            or 705(a)(2)(B) of the Code, without regard to the fact that such
            items are not includable in gross income or are neither currently
            deductible nor capitalized for federal income tax purposes.

                  (iv) Any income, gain or loss attributable to the taxable
            disposition of any Partnership property shall be determined as if
            the adjusted basis of such

                                      20
<Page>

            property as of such date of disposition were equal in amount to
            the Partnership's Carrying Value with respect to such property as
            of such date.

                  (v) In accordance with the requirements of Section 704(b) of
            the Code, any deductions for depreciation, cost recovery or
            amortization attributable to any Contributed Property shall be
            determined as if the adjusted basis of such property on the date it
            was acquired by the Partnership were equal to the Agreed Value of
            such property. Upon an adjustment pursuant to Section 4.6(d) to the
            Carrying Value of any Partnership property subject to depreciation,
            cost recovery or amortization, any further deductions for such
            depreciation, cost recovery or amortization attributable to such
            property shall be determined (A) as if the adjusted basis of such
            property were equal to the Carrying Value of such property
            immediately following such adjustment and (B) using a rate of
            depreciation, cost recovery or amortization derived from the same
            method and useful life (or, if applicable, the remaining useful
            life) as is applied for federal income tax purposes; provided,
            however, that, if the asset has a zero adjusted basis for federal
            income tax purposes, depreciation, cost recovery or amortization
            deductions shall be determined using any reasonable method that the
            General Partner may adopt.

                  (vi) If the Partnership's adjusted basis in depreciable or
            cost recovery property is reduced for federal income tax purposes
            pursuant to Section 48(q)(1) or 48(q)(3) of the Code, the amount of
            such reduction shall, solely for purposes hereof, be deemed to be an
            additional depreciation or cost recovery deduction in the year such
            property is placed in service and shall be allocated among the
            Partners pursuant to Section 5.1. Any restoration of such basis
            pursuant to Section 48(q)(2) of the Code shall to the extent
            possible, be allocated in the year of such restoration as an item of
            income pursuant to Section 5.1.

            (c) A transferee of a Partnership Interest shall succeed to a pro
      rata portion of the Capital Account of the transferor relating to the
      Partnership Interest so transferred.

            (d) (i) Consistent with the provisions of Treasury Regulation
      Section 1.704-1(b)(2)(iv)(f), on an issuance of additional Units for cash
      or Contributed Property or the conversion of the General Partner's
      Partnership Interest to Units pursuant to Section 13.3(b), the Capital
      Accounts of all Partners (other than those holding I-Units) and the
      Carrying Value of each Partnership property immediately prior to such
      issuance shall be adjusted upward or downward to reflect any Unrealized
      Gain or Unrealized Loss attributable to such Partnership property, as if
      such Unrealized Gain or Unrealized Loss had been recognized on an actual
      sale of each such property immediately prior to such issuance and had been
      allocated to the Partners at such time pursuant to Section 5.1.

            (ii) In accordance with Treasury Regulation Section
1.704-1(b)(2)(iv)(f), immediately prior to any distribution to a Partner of any
Partnership property (other than a distribution of cash that is not in
redemption or retirement of a Partnership Interest or an increase in the number
of Outstanding I-Units (or fractions thereof) pursuant to Sections 5.10(a) and
5.10(e)), the Capital Accounts of all Partners other than those holding I-Units
unless the redemption or retirement is pursuant to Section 14.3 and the Carrying
Value of each Partnership

                                      21
<Page>

property shall be adjusted upward or downward to reflect any Unrealized Gain
or Unrealized Loss attributable to such Partnership property, as if such
Unrealized Gain or Unrealized Loss had been recognized in a sale of such
property immediately prior to such distribution for an amount equal to its
fair market value, and had been allocated to the Partners, at such time,
pursuant to Section 5.1(c).

            (iii) Upon an increase in the number of Outstanding I-Units (or
fractions thereof) pursuant to Sections 5.10(a) or 5.10(e), the Capital Accounts
of all I-Units that are Outstanding prior to such increase shall be divided
equally among all I-Units that are Outstanding after such increase (and any
fractional I-Unit shall be allocated a fractional part of such Capital
Accounts).

            4.7  INTEREST.  No interest shall be paid by the Partnership on
Capital Contributions or on balances in Partners' Capital Accounts.

            4.8  NO WITHDRAWAL. No Partner shall be entitled to withdraw any
part of its Capital Contributions or its Capital Account or to receive any
distribution from the Partnership, except as provided herein.

            4.9  LOANS FROM PARTNERS. Loans by a Partner to the Partnership
shall not constitute Capital Contributions. If any Partner shall advance
funds to the Partnership in excess of the amounts required hereunder to be
contributed by it to the capital of the Partnership, the making of such
excess advances shall not result in any increase in the amount of the Capital
Account of such Partner. The amount of any such excess advances shall be a
debt obligation of the Partnership to such Partner and shall be payable or
collectible only out of the Partnership Assets in accordance with the terms
and conditions upon which such advances are made.

            4.10  NO FRACTIONAL UNITS.  Except with respect to I-Units, no
fractional Units shall be issued by the Partnership.

            4.11 SPLITS AND COMBINATIONS.

            (a) Subject to Sections 4.11(d) and 5.10(a) and (d), the General
      Partner may make a Pro Rata distribution of Units or other Partnership
      Securities to all Record Holders or may effect a subdivision or
      combination of Units or other Partnership Securities; provided, however,
      that, subject to Sections 4.11(d) and 5.10(a) and (d), after any such
      distribution, subdivision or combination, each Partner shall have the same
      Percentage Interest in the Partnership as before such distribution,
      subdivision or combination and the Capital Accounts of all such classes of
      distributed, subdivided or combined Units or other Partnership Securities
      Outstanding prior to such distribution, subdivision or combination shall
      be divided equally (on a class by class basis) among all such Units or
      other Partnership Securities Outstanding after such distribution,
      subdivision or combination.

            (b) Except with respect to subdivisions of Outstanding I-Units
      pursuant to Section 5.10(a), whenever such a distribution, subdivision or
      combination of Units or other Partnership Securities is declared, the
      General Partner shall select a Record Date as of which the distribution,
      subdivision or combination shall be effective and shall send

                                      22
<Page>

      notice of the distribution, subdivision or combination at least 20 days
      prior to such Record Date to each Record Holder as of a date not less
      than 10 days prior to the date of such notice. The General Partner also
      may cause a firm of independent public accountants selected by it to
      calculate the number of Units to be held by each Record Holder after
      giving effect to such distribution, subdivision or combination. The
      General Partner shall be entitled to rely on any certificate provided
      by such firm as conclusive evidence of the accuracy of such calculation.

            (c) Promptly following any such distribution, subdivision or
      combination, the General Partner may cause Unit Certificates to be issued
      to the Record Holders of Units as of the applicable Record Date
      representing the new number of Units held by such Record Holders, or the
      General Partner may adopt such other procedures as it may deem appropriate
      to reflect such distribution, subdivision or combination; provided,
      however, if any such distribution, subdivision or combination results in a
      smaller total number of Units Outstanding, the General Partner shall
      require, as a condition to the delivery to a Record Holder of such new
      Unit Certificate, the surrender of any Unit Certificate held by such
      Record Holder immediately prior to such Record Date.

            (d) Except with respect to I-Units, the Partnership shall not issue
      fractional Units upon any distribution, subdivision or combination of
      Units. If a distribution, subdivision or combination of Units would result
      in the issuance of fractional Units but for the provision of Section 4.10
      and this Section 4.11(d), each fractional Unit (other than a fractional
      I-Unit) shall be rounded to the nearest whole Unit (and a 0.5 Unit shall
      be rounded to the next higher Unit).

            4.12  I-UNITS. Pursuant to Section 4.4, the General Partner
hereby designates and creates a special class of Units designated "I-UNITS"
and fixes the designations, preferences and relative, participating, optional
or other special rights, powers and duties of the holders of the I-Units as
follows:

            (a) Except as otherwise provided in Section 5.1(c), a holder of an
      I-Unit will receive no allocations of income, gain, loss or deductions.
      Except for distributions made in accordance with Sections 14.3(b) and
      14.3(c), no distributions or payments shall be made to a holder of an
      I-Unit except in additional I-Units (or fractions thereof) or a security
      that has in all material respects the same rights and privileges as the
      I-Units, in accordance with Section 5.10.

            (b)   The number of Outstanding I-Units may be subdivided
      pursuant to Section 5.10.

            (c) Except as otherwise provided in this Agreement, each I-Unit
      shall have the rights of a holder of a Common Unit with respect to voting.
      Except as otherwise provided in this Agreement, all Units shall vote or
      consent together as a single class on all matters submitted for a vote or
      consent of the Outstanding Units.

                          ALLOCATIONS AND DISTRIBUTIONS

            5.1  ALLOCATIONS FOR CAPITAL ACCOUNT PURPOSES. For purposes of
maintaining the Capital Accounts and in determining the rights of the
Partners among themselves, the Partnership's items of income, gain, loss and
deduction (computed in accordance with Section 4.6(b)) shall be allocated
among the Partners in each taxable year (or portion thereof) as provided
herein below.

            (a) NET INCOME. All items of income, gain, loss and deduction taken
      into account in computing Net Income for such taxable period shall be
      allocated in the same manner as such Net Income is allocated hereunder,
      which Net Income shall be allocated as follows:

                  (i) FIRST, 100% to the General Partner until the aggregate
            Net Income allocated to the General Partner pursuant to this
            Section 5.1(a)(i) for the current taxable year and all previous
            taxable years is equal to the aggregate Net Losses allocated to
            the General Partner pursuant to Section 5.1(b)(ii) for all
            previous taxable years; and

                  (ii) SECOND, the balance, if any, 98% to the Limited Partners
            holding Common Units, Pro Rata, and 2% to the General Partner.

            (b) NET LOSSES. All items of income, gain, loss and deduction taken
      into account in computing Net Losses for such taxable period shall be
      allocated in the same manner as such Net Losses are allocated hereunder,
      which Net Losses shall be allocated as follows:

                  (i) FIRST, 98% to the Limited Partners holding Common Units,
            Pro Rata, and 2% to the General Partner; PROVIDED, that Net Losses
            shall not be allocated pursuant to this Section 5.1(b)(i) to the
            extent that such allocation would cause any Partner to have a
            deficit balance in its Adjusted Capital Account at the end of such
            taxable year (or increase any existing deficit balance in its
            Adjusted Capital Account); and

                  (ii) SECOND, the balance, if any, 100% to the General
            Partner.

            (c) NET TERMINATION GAINS AND LOSSES. After giving effect to the
      special allocations set forth in Sections 5.1(d) and 5.1(e), all items of
      income, gain, loss and deduction taken into account in computing Net
      Termination Gain or Net Termination Loss for such taxable period shall be
      allocated in the same manner as such Net Termination Gain or Net
      Termination Loss is allocated hereunder. All allocations under this
      Section 5.1(c) shall be made after Capital Account balances have been
      adjusted by all other allocations provided under this Section 5.1 and
      after all distributions of Available Cash provided under Section 5.5 have
      been made with respect to such taxable period.

                  (i) If a Net Termination Gain is recognized, such Net
            Termination Gain shall be allocated between the General Partner and
            the Limited Partners in the

                                      24

<Page>

            following manner (and the Adjusted Capital Accounts of the Partners
            shall be increased by the amount so allocated in each of the
            following subclauses, in the order listed, before an allocation
            is made pursuant to the next succeeding subclause):

                  (A) FIRST, to each Partner having a deficit balance in its
            Adjusted Capital Account, in the proportion that such deficit
            balance bears to the total deficit balances in the Adjusted Capital
            Accounts of all Partners, until each such Partner has been allocated
            Net Termination Gain equal to any such deficit balance in its
            Adjusted Capital Account;

                  (B) SECOND, if the Adjusted Capital Account of an I-Unit is
            less than the Adjusted Capital Account of a Common Unit, 98% to the
            Limited Partners holding I-Units or fractions thereof, Pro Rata, and
            2% to the General Partner until the Adjusted Capital Account of each
            I-Unit or fractions thereof, equals the Adjusted Capital Account of
            each Common Unit, or comparable fraction thereof, or, if the
            Adjusted Capital Account of an I-Unit is greater than the Adjusted
            Capital Account of a Common Unit, 98% to the Limited Partners
            holding Common Units, Pro Rata, and 2% to the General Partner until
            the Adjusted Capital Account of each Common Unit equals the Adjusted
            Capital Account of each I-Unit;

                  (C) THIRD, 98% to the Limited Partners holding I-Units, or
            fractions thereof, and Common Units, Pro Rata, and 2% to the General
            Partner, until each Limited Partner's Adjusted Capital Account
            (determined on a per Unit basis) is equal to the sum of (aa) the
            Unrecovered Capital plus (bb) any cumulative arrearages in the
            payment of the Minimum Quarterly Distribution for any quarter
            commencing after December 31, 1996;

                  (D) FOURTH, 85% to all Limited Partners holding I-Units, or
            fractions thereof, and Common Units, Pro Rata, and 15% to the
            General Partner until each such Limited Partner's Adjusted Capital
            Account in respect of its Units or fractions thereof (determined on
            a per Unit basis) is equal to the sum of (aa) the Unrecovered
            Capital, plus (bb) any cumulative arrearages in the payment of the
            Minimum Quarterly Distribution for any quarter commencing after
            December 31, 1996, plus (cc) the excess of the First Target
            Distribution over the Minimum Quarterly Distribution for each
            quarter of the Partnership's existence, less (dd) the amount of any
            distributions of Available Cash that is deemed to be Cash from
            Operations that was distributed pursuant to Section 5.5(d) (the sum
            of (bb) plus (cc) less (dd) is hereinafter defined as the "FIRST
            LIQUIDATION TARGET AMOUNT");

                  (E) FIFTH, 75% to all Limited Partners holding I-Units, or
            fractions thereof, and Common Units, Pro Rata, and 25% to the
            General Partner until each such Limited Partner's Adjusted Capital
            Account in respect of its Units or fractions thereof (determined on
            a per Unit basis) is equal to the sum of (aa) the Unrecovered
            Capital, plus (bb) the First Liquidation Target Amount, plus (cc)
            the excess of the Second Target Distribution over the First Target
            Distribution for

                                      25

<Page>

            each quarter of the Partnership's existence less (dd) the amount of
            any distributions of Available Cash that is deemed to be Cash from
            Operations distributed pursuant to Section 5.5(e); and

                  (F) SIXTH, the balance, if any, 50% to all Limited Partners
            holding I-Units, or fractions thereof, and Common Units, Pro Rata,
            and 50% to the General Partner.

                  (ii) If a Net Termination Loss is recognized, such Net
            Termination Loss shall be allocated to the Partners in the following
            manner:

                  (A) FIRST, if the Adjusted Capital Account of an I-Unit, or
            fraction thereof, is less than the Adjusted Capital Account of a
            Common Unit, 98% to the Limited Partners holding Common Units, Pro
            Rata, and 2% to the General Partner until the Adjusted Capital
            Account of each Common Unit equals the Adjusted Capital Account of
            each I-Unit or, if the Adjusted Capital Account of an I-Unit is
            greater than the Adjusted Capital Account of a Common Unit, 98% to
            the Limited Partners holding I-Units, or fractions thereof, Pro
            Rata, and 2% to the General Partner until the Adjusted Capital
            Account of each I-Unit, or fraction thereof, equals the Adjusted
            Capital Account of each Common Unit, or comparable fraction thereof;

                  (B) SECOND, 100% to the General Partner and the Limited
            Partners in proportion to, and to the extent of, the positive
            balances in their respective Adjusted Capital Accounts until all
            such balances are reduced to zero; and

                  (C) THIRD, the balance, if any, 100% to the General Partner.

            (d)   SPECIAL ALLOCATIONS.  Notwithstanding any other
      provisions of this Section 5.1 (other than Section 5.1(e)), the
      following special allocations shall be made for such taxable period:

                  (i) PRIORITY ALLOCATIONS. (A) If the amount of cash or the Net
            Agreed Value of any property distributed (except cash or property
            distributed pursuant to Section 14.3 or 14.4) to any Limited Partner
            holding Units during a taxable year is greater (on a per Unit basis)
            than the amount of cash or the Net Agreed Value of property
            distributed to the other Limited Partners holding Units other than
            I-Units (on a per Unit basis), then (1) each Limited Partner holding
            Units receiving such greater cash or property distribution shall be
            allocated gross income in an amount equal to the product of (x) the
            amount by which the distribution (on a per Unit basis) to such
            Limited Partner holding Units exceeds the distribution (on a per
            Unit basis) to the Limited Partners holding Units other than I-Units
            receiving the smallest distribution and (y) the number of Units
            owned by the Limited Partner holding Units receiving the greater
            distribution; and (2) the General Partner shall be allocated gross
            income in an amount equal to 2.04% of the sum of the amounts
            allocated in clause (1) above.

                                      26

<Page>

                  (B) After the application of Section 5.1(d)(i)(A), all or a
            portion of the remaining items of Partnership gross income or gain
            for the taxable period, if any, shall be allocated 100% to the
            General Partner (or its assignee) until the aggregate amount of such
            items allocated to the General Partner (or its assignee) pursuant to
            this paragraph (d)(i)(B) for the current taxable period and all
            previous taxable periods is equal to the cumulative amount of all
            Incentive Distributions made to the General Partner (or its
            assignee) from the Closing Date to a date 45 days after the end of
            the current taxable period.

                  (C) At the election of the General Partner with respect to any
            taxable period, all or a portion of the remaining items of
            Partnership gross income or gain for the taxable period, if any,
            shall be allocated to each Partner holding Class B Common Units, in
            the proportion that the respective number of Class B Common Units
            held by such Partner bears to the total number of Class B Common
            Units then outstanding, until such Partner has been allocated an
            amount of gross income or gain which increases the Capital Account
            maintained with respect to such Class B Common Units to an amount
            such that the Capital Account attributable to each Class B Common
            Unit held by the Partner, on a per Unit basis, is equal to the
            Capital Account, stated on a per Unit basis, underlying any Class A
            Common Unit Outstanding at the time of determination. The purpose of
            this allocation is to establish uniformity between the Capital
            Accounts underlying Class B Common Units and the Capital Accounts
            underlying Class A Common Units immediately prior to the change of
            all Class A Common Units into Class B Common Units pursuant to
            Section 5.6.

                  (ii) NONRECOURSE LIABILITIES. For purposes of Treasury
            Regulation Section 1.752-3(a)(3), the Partners agree that
            Nonrecourse Liabilities of the Partnership in excess of the sum of
            (A) the amount of Partnership Minimum Gain and (B) the total amount
            of Nonrecourse Built-in Gain shall be allocated among the General
            Partner and the holders of Common Units in accordance with the
            allocation of Net Income set forth in Section 5.1(a)(ii).

                  (iii) DISCRETIONARY ALLOCATION. (A) Notwithstanding any other
            provision of Section 5.1(a), (b) or (c), the Agreed Allocations
            shall be adjusted so that, to the extent possible, the net amount of
            items of income, gain, loss and deduction allocated to each Partner
            pursuant to the Required Allocations and the Agreed Allocations,
            together, shall be equal to the net amount of such items that would
            have been allocated to each such Partner under the Agreed
            Allocations had there been no Required Allocations; provided,
            however, that for purposes of applying this Section 5.1(d)(iii)(A),
            it shall be assumed that all chargebacks pursuant to Sections
            5.1(e)(i) and (ii) have occurred.

                  (B) The General Partner shall have reasonable discretion, with
            respect to each taxable year, to (1) apply the provisions of Section
            5.1(d)(iii)(A) in whatever fashion as is most likely to minimize the
            economic distortions that might otherwise result from the Required
            Allocations, and (2) divide all

                                      27

<Page>

            allocations pursuant to Section 5.1(d)(iii)(A) among the Partners
            in a manner that is likely to minimize such economic distortions.

            (e)   REQUIRED ALLOCATIONS.  Notwithstanding any other
      provision of this Section 5.1, the following special allocations shall be
      made for such taxable period:

                  (i) PARTNERSHIP MINIMUM GAIN CHARGEBACK. Notwithstanding the
            other provisions of this Section 5.1, if there is a net decrease in
            Partnership Minimum Gain during any Partnership taxable period, each
            Partner shall be allocated items of Partnership income and gain for
            such period (and, if necessary, subsequent periods) in the manner
            and amounts provided in Treasury Regulation Sections 1.704-2(f)(6),
            1.704-2(g)(2) and 1.704-2(j)(2)(i), or any successor provisions. For
            purposes of this Section 5.1(e), each Partner's Adjusted Capital
            Account balance shall be determined, and the allocation of income or
            gain required hereunder shall be effected, prior to the application
            of any other allocations pursuant to this Section 5.1 with respect
            to such taxable period.

                  (ii) CHARGEBACK OF MINIMUM GAIN ATTRIBUTABLE TO PARTNER
            NONRECOURSE DEBT. Notwithstanding the other provisions of this
            Section 5.1 (other than 5.1(e)(i)), except as provided in Treasury
            Regulation Section 1.704-2(i)(4) if there is a net decrease in
            Minimum Gain Attributable to Partner Nonrecourse Debt during any
            Partnership taxable period, any Partner with a share of Minimum Gain
            Attributable to Partner Nonrecourse Debt at the beginning of such
            taxable period shall be allocated items of Partnership income and
            gain for such period (and, if necessary, subsequent periods) in the
            manner and amounts provided in Treasury Regulation Sections
            1.704-2(a)(4) and 1.704-2(j)(ii), or any successor provisions. For
            purposes of this Section 5.1, each Partner's Adjusted Capital
            Account balance shall be determined and the allocation of income or
            gain required hereunder shall be effected, prior to the application
            of any other allocations pursuant to this Section 5.1(e), other than
            Section 5.1(e)(i), with respect to such taxable period.

                  (iii) QUALIFIED INCOME OFFSET. In the event any Limited
            Partner unexpectedly receives adjustments, allocations or
            distributions described in Treasury Regulation Sections
            1.704-1(b)(2)(ii)(d)(4), 1.704-1(b)(2)(ii)(d)(5), or
            1.704-1(b)(2)(ii)(d)(6), items of Partnership income and gain shall
            be specifically allocated to such Partner in an amount and manner
            sufficient to eliminate, to the extent required by the Treasury
            Regulations promulgated under Section 704(b) of the Code, the
            deficit balance, if any, in its Adjusted Capital Account created by
            such adjustments, allocations or distributions as quickly as
            possible unless such deficit balance is otherwise eliminated
            pursuant to Section 5.1(e)(i) or 5.1(e)(ii).

                  (iv) GROSS INCOME ALLOCATIONS. In the event any Partner has a
            deficit balance in its Adjusted Capital Account at the end of any
            Partnership taxable period, that is in excess of the sum of (A) the
            amount such Partner is obligated to restore and (B) the amount such
            Partner is deemed to be obligated to restore pursuant to Treasury
            Regulation Sections 1.704-2(g) and 1.704-2(i)(5), such Partner shall
            be specially allocated items of Partnership gross income and gain in

                                     28

<Page>

            the amount of such excess as quickly as possible; provided, that an
            allocation pursuant to this Section 5.1(e)(iv) shall be made only if
            and to the extent that such Partner would have a deficit balance in
            its Adjusted Capital Account after all other allocations provided in
            this Section 5.1 have been tentatively made as if this Section
            5.1(e)(iv) was not in this Agreement.

                  (v) NONRECOURSE DEDUCTIONS. Nonrecourse Deductions for any
            taxable period shall be allocated to the Partners in accordance with
            their respective Percentage Interests. If the General Partner
            determines in its good faith discretion that the Partnership's
            Nonrecourse Deductions must be allocated in a different ratio to
            satisfy the safe harbor requirements of the Treasury Regulations
            promulgated under Section 704(b) of the Code, the General Partner is
            authorized, upon notice to the Limited Partners, to revise the
            prescribed ratio to the numerically closest ratio which does satisfy
            such requirements.

                  (vi) PARTNER NONRECOURSE DEDUCTIONS. Partner Nonrecourse
            Deductions for any taxable period shall be allocated 100% to the
            Partner that bears the Economic Risk of Loss for such Partnership
            Nonrecourse Debt to which such Partner Nonrecourse Deductions are
            attributable in accordance with Treasury Regulation Section
            1.704-2(i). If more than one Partner bears the Economic Risk of Loss
            with respect to a Partner Nonrecourse Debt, such Partner Nonrecourse
            Deductions attributable thereto shall be allocated between or among
            such Partners in accordance with the ratios in which they share such
            Economic Risk of Loss.

            (f) The Limited Partners holding Class A Common Units will be
      allocated gross income during each taxable year of the Partnership that
      would otherwise be allocated to the Limited Partners holding Class B
      Common Units pursuant to this Agreement (other than Section 5.1(e)), to
      the extent such an amount of gross income exists, in accordance with the
      following schedule:

Notwithstanding the above, no allocation of gross income shall be made
pursuant to this Section 5.1(f) (or the amount of such allocation shall be
reduced) in any taxable year of the Partnership to the extent that a
purchaser of a Class A Common Unit in the offering made pursuant to the
Registration Statement would be allocated, pursuant to this Agreement, an
amount of federal taxable income with respect to such taxable year that would
exceed 65% of the amount of Available Cash distributed to such a Unitholder
with respect to that taxable year. In addition, no allocation of gross income
shall be made pursuant to this Section 5.1(f) for any taxable year including
or following the change of all Class A Common Units into Class B Common Units
pursuant to Section 5.6.

            5.2 ALLOCATIONS FOR TAX PURPOSES.

            (a) Except as otherwise provided herein, for federal income tax
      purposes, each item of income, gain, loss and deduction which is
      recognized by the Partnership for federal income tax purposes shall be
      allocated among the Partners in the same manner as its correlative item of
      "book" income, gain, loss or deduction is allocated pursuant to Section
      5.1.

            (b) In an attempt to eliminate Book-Tax Disparities attributable
      to a Contributed Property or Adjusted Property, items of income, gain,
      loss, depreciation, amortization and cost recovery deductions shall be
      allocated for federal income tax purposes among the Partners as follows:

                  (i) (A) In the case of a Contributed Property, such items
            attributable thereto shall be allocated among the Partners in the
            manner provided under Section 704(c) of the Code that takes into
            account the variation between the Agreed Value of such property and
            its adjusted basis at the time of contribution; and (B) except as
            otherwise provided in Section 5.2(b)(iii), any item of Residual Gain
            or Residual Loss attributable to a Contributed Property shall be
            allocated among the Partners in the same manner as its correlative
            item of "book" gain or loss is allocated pursuant to Section 5.1.

                  (ii) (A) In the case of an Adjusted Property, such items shall
            (1) first, be allocated among the Partners in a manner consistent
            with the principles of Section 704(c) of the Code to take into
            account the Unrealized Gain or Unrealized Loss attributable to such
            property and the allocations thereof pursuant to Section 4.6(d)(i)
            or (ii), and (2) second, in the event such property was originally a
            Contributed Property, be allocated among the Partners in a manner
            consistent with Section 5.2(b)(i)(A); and (B) except as otherwise
            provided in Section 5.2(b)(iii), any item of Residual Gain or
            Residual Loss attributable to an Adjusted Property shall be
            allocated among the Partners in the same manner as its correlative
            item of "book" gain or loss is allocated pursuant to Section 5.1.

                                      30

<Page>

                  (iii) Any items of income, gain, loss or deduction otherwise
            allocable under Section 5.2(b)(i)(B) or 5.2(b)(ii)(B) shall be
            subject to allocation by the General Partner in a manner designed to
            eliminate, to the maximum extent possible, Book-Tax Disparities in a
            Contributed Property or Adjusted Property otherwise resulting from
            the application of the "ceiling" limitation (under Section 704(c) of
            the Code or Section 704(c) principles) to the allocations provided
            under Section 5.2(b)(i)(A) or 5.2(b)(ii)(A).

            (c) For the proper administration of the Partnership or for the
      preservation of uniformity of the Units (or any class or classes thereof),
      the General Partner shall have sole discretion to (i) adopt such
      conventions as it deems appropriate in determining the amount of
      depreciation, amortization and cost recovery deductions; (ii) make special
      allocations for federal income tax purposes of income (including, without
      limitation, gross income) or deductions; and (iii) amend the provisions of
      this Agreement as appropriate (x) to reflect the proposal or promulgation
      of Treasury Regulations under Section 704(b) or Section 704(c) of the Code
      or (y) otherwise to preserve or achieve uniformity of the Units (or any
      class or classes thereof). The General Partner may adopt such conventions,
      make such allocations and make such amendments to this Agreement as
      provided in this Section 5.2(c) only if such conventions, allocations or
      amendments would not have a material adverse effect on the Partners, the
      holders of any class or classes of Units issued and Outstanding of the
      Partnership, and if such allocations are consistent with the principles of
      Section 704 of the Code.

            (d) The General Partner in its sole discretion may determine to
      depreciate the portion of an adjustment under Section 743(b) of the Code
      attributable to unrealized appreciation in any Adjusted Property (to the
      extent of the unamortized Book-Tax Disparity) using a predetermined rate
      derived from the depreciation method and useful life applied to the
      Partnership's common basis of such property, despite the inconsistency of
      such approach with Treasury Regulation Section 1.167(c)-1(a)(6). If the
      General Partner determines that such reporting position cannot reasonably
      be taken, the General Partner may adopt a depreciation convention under
      which all purchasers acquiring Units in the same month would receive
      depreciation, based upon the same applicable rate as if they had purchased
      a direct interest in the Partnership's property. If the General Partner
      chooses not to utilize such aggregate method, the General Partner may use
      any other reasonable depreciation convention to preserve the uniformity of
      the intrinsic tax characteristics of any Units that would not have a
      material adverse effect on the Limited Partners or the Record Holders of
      any class or classes of Units. In addition, for purposes of computing the
      adjustments under Section 743(b) of the Code, the General Partner shall be
      authorized (but not required) to adopt a convention whereby the price paid
      by a transferee of Units will be deemed to be the lowest quoted trading
      price of the Units on any National Securities Exchange on which such Units
      are traded during the calendar month in which such transfer is deemed to
      occur pursuant to Section 5.2(g) without regard to the actual price paid
      by such transferee.

            (e) Any gain allocated to the Partners upon the sale or other
      taxable disposition of any Partnership asset shall, to the extent
      possible, after taking into account other required allocations of gain
      pursuant to this Section 5.2 be characterized as

                                      31

<Page>

      Recapture Income in the same proportions and to the same extent as such
      Partners (or their predecessors in interest) have been allocated any
      deductions directly or indirectly giving rise to the treatment of such
      gains as Recapture Income.

            (f) All items of income, gain, loss, deduction and credit recognized
      by the Partnership for federal income tax purposes and allocated to the
      Partners in accordance with the provisions hereof shall be determined
      without regard to any election under Section 754 of the Code which may be
      made by the Partnership; provided, however, that such allocations, once
      made, shall be adjusted as necessary or appropriate to take into account
      those adjustments permitted or required by Sections 734 and 743 of the
      Code.

            (g) Each item of Partnership income, gain, loss and deduction
      attributable to a transferred Partnership Interest of the General Partner
      or to transferred Units shall, for federal income tax purposes, be
      determined on an annual basis and prorated on a monthly basis and shall be
      allocated to the Partners as of the close of the New York Stock Exchange
      on the last day of the preceding month; provided, however, that gain or
      loss on a sale or other disposition of any assets of the Partnership other
      than in the ordinary course of business shall be allocated to the Partners
      as of the opening of the New York Stock Exchange on the first Business Day
      of the month in which such gain or loss is recognized for federal income
      tax purposes. The General Partner may revise, alter or otherwise modify
      such methods of allocation as it determines necessary, to the extent
      permitted or required by Section 706 of the Code and the regulations or
      rulings promulgated thereunder.

            (h) Allocations that would otherwise be made to a Limited Partner
      under the provisions of this Article V shall instead be made to the
      beneficial owner of Units held by a nominee in any case in which the
      nominee has furnished the identity of such owner to the Partnership in
      accordance with Section 6031(c) of the Code or any other method acceptable
      to the General Partner in its sole discretion.

            5.3  REQUIREMENT AND CHARACTERIZATION OF DISTRIBUTIONS.

            (a) Within 45 days following the end of each calendar quarter the
      Partnership shall distribute to the Partners and retain for reinvestment
      in its business in accordance with this Article V, an amount equal to 100%
      of Available Cash with respect to such quarter. Distributions of Available
      Cash by the Partnership to the Partners shall be made as of the Record
      Date selected by the General Partner in its reasonable discretion. All
      amounts of Available Cash distributed and retained by the Partnership on
      any date from any source shall be deemed to be Cash from Operations until
      the sum of all amounts of Available Cash theretofore distributed by the
      Partnership to the Partners pursuant to Section 5.4 of the Second Amended
      and Restated Agreement or any substantially similar provisions of any
      other Prior Agreements and Section 5.5 and retained by the Partnership
      pursuant to Section 5.5 equals the aggregate amount of all Cash from
      Operations of the Partnership from the Partnership Inception through the
      end of the calendar quarter immediately preceding such distribution and
      retention. Any remaining amounts of Available Cash distributed and
      retained by the Partnership on such date shall be deemed to be Cash from
      Interim Capital Transactions.

                                      32

<Page>

            (b) Notwithstanding the definitions of Available Cash and Cash from
      Operations contained herein, disbursements (including, without limitation,
      contributions to any Operating Subsidiary or disbursements on behalf of
      any Operating Subsidiary) made or cash reserves established after the end
      of any quarter shall be deemed to have been made or established, for
      purposes of determining Available Cash and Cash from Operations, within
      such quarter if the General Partner so determines. Notwithstanding the
      foregoing, in the event of the dissolution and liquidation of the
      Partnership, all proceeds of such liquidation shall be applied and
      distributed in accordance with, and subject to the terms and conditions
      of, Sections 14.3 and 14.4.

            5.4  INTENTIONALLY OMITTED.

            5.5  CASH FROM OPERATIONS. Available Cash with respect to any
calendar quarter that is deemed to be Cash from Operations pursuant to the
provisions of Section 5.3 or 5.7 shall be distributed by the Partnership to
the Partners as follows:

            (a) FIRST, 98% to all Limited Partners holding Common Units, Pro
      Rata, and 2% to the General Partner until the Partnership has distributed
      in respect of each Common Unit then Outstanding an amount of cash equal to
      the Minimum Quarterly Distribution;

            (b) SECOND, 85% to all Limited Partners holding Common Units, Pro
      Rata, and 15% to the General Partner until the Partnership has distributed
      in respect of each Common Unit then Outstanding an amount of cash equal to
      the excess of the First Target Distribution over the Minimum Quarterly
      Distribution;

            (c) THIRD, 75% to all Limited Partners holding Common Units, Pro
      Rata, and 25% to the General Partner until the Partnership has distributed
      in respect of each Common Unit then Outstanding an amount of cash equal to
      the excess of the Second Target Distribution over the First Target
      Distribution; and

            (d) FOURTH, 50% to all Limited Partners holding Common
      Units, Pro Rata, and 50% to the General Partner;

PROVIDED, HOWEVER, that the Partnership may not make a distribution of
Available Cash to Limited Partners holding Common Units pursuant to this
Section 5.5, unless at the same time that it makes such distribution, the
Partnership shall retain in respect of each I-Unit then Outstanding an amount
of Available Cash equal to the quotient obtained by dividing (i) the cash
distribution then being made on a Common Unit pursuant to this Section 5.5 by
(ii) .98; and

PROVIDED, FURTHER, that if the Minimum Quarterly Distribution, the First
Target Distribution and the Second Target Distribution have been reduced to
zero pursuant to Section 5.9(a)(ii), then distributions of Available Cash
that is deemed to be Cash from Operations with respect to any quarter will be
made 98% to all Limited Partners holding Class A Common Units, Pro Rata, and
2% to the General Partner until there has been distributed in respect of each
Class A Common Unit then Outstanding, pursuant to Section 5.4 of the Second
Amended and Restated Agreement or any substantially similar provisions of any
other Prior Agreements and this Section 5.5 including this proviso, Available
Cash that is deemed to be Cash from Operations since

                                      33

<Page>

Partnership Inception equal to the Minimum Quarterly Distribution (as from
time to time adjusted) for all periods since Partnership Inception, and
thereafter in accordance with Section 5.5(d).

            5.6  CHANGE OF CLASS A COMMON UNITS AND CLASS B COMMON UNITS. At
such time as the General Partner determines, based on advice of counsel, that
all Class B Common Units have, as a substantive matter, like intrinsic
economic and federal income tax characteristics, in all material respects, to
the intrinsic economic and federal income tax characteristics of the Class A
Common Units then Outstanding, all differences and distinctions between Class
A Common Units and Class B Common Units shall automatically cease and all
Class A Common Units and Class B Common Units shall thereafter be one class
of Units called "Common Units."

            5.7  CASH FROM INTERIM CAPITAL TRANSACTIONS. Available Cash that
is deemed to be Cash from Interim Capital Transactions shall be distributed,
unless the provisions of Section 5.3 require otherwise, 98% to all Limited
Partners holding Common Units, Pro Rata, and 2% to the General Partner until
a hypothetical holder of a Class A Common Unit acquired at the time of the
Initial Offering has received with respect to each Class A Common Unit, from
Partnership Inception through such date, distributions of Available Cash that
are deemed to be Cash from Interim Capital Transactions in an aggregate
amount per Class A Common Unit equal to the Initial Unit Price; PROVIDED,
HOWEVER, that the Partnership may not make a distribution of Available Cash
to Limited Partners holding Common Units pursuant to this Section 5.7, unless
at the same time that it makes any such distribution, the Partnership shall
retain in respect of each I-Unit then Outstanding an amount of Available Cash
equal to the quotient obtained by dividing (i) the cash distribution then
being made on a Common Unit pursuant to this Section 5.7 by (ii) .98.
Thereafter, all Available Cash shall be distributed as if it were Cash from
Operations and shall be distributed in accordance with Section 5.5.

            5.8  DEFINITIONS.  As used herein,

            (a) "AVAILABLE CASH" means, with respect to any calendar quarter,
      (i) the sum of (A) all cash receipts of the Partnership during such
      quarter from all sources (including, without limitation, distributions of
      any Operating Subsidiary's "Available Cash" (as that term is defined in
      the respective Operating Subsidiary Agreement) received by the Partnership
      pursuant to the respective Operating Subsidiary Agreement) and (B) any
      reduction in cash reserves established in prior quarters (either by
      reversal or utilization), less (ii) the sum of (aa) all cash disbursements
      of the Partnership during such quarter, and (bb) any cash reserves
      established in such quarter in such amounts as the General Partner
      determines to be necessary or appropriate in its reasonable discretion (x)
      to provide for the proper conduct of the business of the Partnership
      (including reserves for possible rate refunds or future capital
      expenditures) or (y) to provide funds for distributions with respect to
      any of the next four calendar quarters and (cc) any other cash reserves
      established in such quarter in such amounts as the General Partner
      determines in its reasonable discretion to be necessary because the
      distribution of such amounts would be prohibited by applicable law or by
      any loan agreement, security agreement, mortgage, debt instrument or other
      agreement or obligation to which the Partnership is a party or by which it
      is bound or its assets are subject. Taxes paid by the Partnership on
      behalf of, or

                                      34

<Page>

      amounts withheld with respect to, all or less than all of the Partners
      shall not be considered cash disbursements of the Partnership which
      reduce Available Cash, but the payment or withholding thereof shall
      be deemed to be a distribution of Available Cash to such Partners.
      Alternatively, in the discretion of the General Partner, such taxes (if
      pertaining to all Partners) may be considered to be cash disbursements
      of the Partnership which reduce Available Cash, but the payment or
      withholding thereof shall not be deemed to be a distribution of Available
      Cash to such Partners. Notwithstanding the foregoing, Available Cash shall
      not include any cash receipts or reductions in reserves or take into
      account any disbursements made or reserves established after commencement
      of the dissolution and liquidation of the Partnership. For purposes of
      determining "Available Cash," the aggregate Equivalent Non-Cash Amount for
      all I-Units with respect to any calendar quarter will be disregarded for
      purposes of determining "Available Cash" in future quarters.

            (b) "CASH FROM INTERIM CAPITAL TRANSACTIONS" means, at any date,
      such amounts of Available Cash as are deemed to be Cash from Interim
      Capital Transactions pursuant to Section 5.3.

            (c) "CASH FROM OPERATIONS" means, at any date but prior to
      commencement of the dissolution and liquidation of the Partnership, on a
      cumulative basis, the cash balance of the Partnership and any Operating
      Subsidiary at Partnership Inception, excluding any such cash proceeds to
      the Partnership from the exercise of the Underwriters' over-allotment
      option granted in the Underwriting Agreement, plus all cash receipts of
      the Partnership and any Operating Subsidiary from their operations
      (excluding any cash proceeds from any Interim Capital Transactions) during
      the period since the Partnership Inception through such date less the sum
      of (i) all cash operating expenditures of the Partnership and any
      Operating Subsidiary during such period, including, without limitation,
      taxes imposed on the Partnership or any Operating Subsidiary as an entity,
      (ii) all cash debt service payments of the Partnership and any Operating
      Subsidiary during such period (other than payments or prepayments of
      principal and premium required by reason of loan agreements (including
      covenants and default provisions therein) or by lenders, in each case in
      connection with sales or other dispositions of assets or made in
      connection with refinancings or refundings of indebtedness; provided, that
      any payment or prepayment of principal, whether or not then due, shall be
      determined at the election and in the discretion of the General Partner to
      be refunded or refinanced by any indebtedness incurred or to be incurred
      by the Partnership or any Operating Subsidiary simultaneously with or
      within 180 days prior to or after such payment or prepayment to the extent
      of the principal amount of such indebtedness so incurred), (iii) all cash
      capital expenditures of the Partnership and any Operating Subsidiary
      during such period necessary to maintain the service capability of the
      Transportation System, (iv) an amount equal to the incremental revenues
      collected pursuant to a rate increase that are, at such date, subject to
      possible refund and for which the General Partner has established a cash
      reserve, (v) any cash reserves outstanding as of such date which the
      General Partner determines in its reasonable discretion to be necessary or
      appropriate to provide for the future cash payment of items of the type
      referred to in clauses (i) through (iii) of this sentence and (vi) any
      cash reserves outstanding as of such date that the General Partner
      determines to be necessary or appropriate in its reasonable discretion to
      provide funds for

                                      35

<Page>

      distributions with respect to any one or more of the next four calendar
      quarters, all as determined on a consolidated basis and after elimination
      of intercompany items. Taxes paid by the Partnership on behalf of, or
      amounts withheld with respect to, all or less than all of the Partners
      shall not be considered cash operating expenditures of the Partnership
      which reduce Cash from Operations, but the payment or withholding thereof
      shall be deemed to be a distribution of Available Cash to such Partners.
      Alternatively, in the discretion of the General Partner, such taxes (if
      pertaining to all Partners) may be considered to be cash disbursements of
      the Partnership which reduce Cash from Operations, but the payment or
      withholding thereof shall not be deemed to be a distribution of Available
      Cash to such Partners. For purposes of the foregoing, reserves do not
      include reserves outstanding at Partnership Inception.

            (d)   Intentionally Omitted;

            (e)   Intentionally Omitted;

            (f)   Intentionally Omitted;

            (h) "FIRST TARGET DISTRIBUTION" means $0.70 per Unit per calendar
      quarter, subject to adjustment in accordance with Sections 5.9 and 9.6.

      debt securities (other than for working capital purposes and for items
      purchased on open account in the ordinary course of business) by the
      Partnership or any Operating Subsidiary, (ii) sales of equity interests by
      the Partnership or any Operating Subsidiary and (iii) sales or other
      voluntary or involuntary dispositions of any assets of the Partnership or
      any Operating Subsidiary (other than (x) sales or other dispositions of
      inventory in the ordinary course of business, (y) sales or other
      dispositions of other current assets including accounts receivable or (z)
      sales or other dispositions of assets as a part of normal retirements or
      replacements), in each case prior to the commencement of the dissolution
      and liquidation of the Partnership. The General Partner shall have the
      right to determine in its reasonable discretion whether inventory
      reductions shall be considered in the ordinary course of business or such
      a normal retirement.

            (j) "MINIMUM QUARTERLY DISTRIBUTION" means $0.59 per Unit per
      calendar quarter, subject to adjustment in accordance with Sections 5.9
      and 9.6.

            (k) "NET INCOME" means, for any taxable period, the excess, if any,
      of the Partnership's items of income and gain (other than those items
      attributable to dispositions constituting Termination Capital
      Transactions) for such taxable period over the Partnership's items of loss
      and deduction (other than those items attributable to dispositions
      constituting Termination Capital Transactions) for such taxable period.
      The items included in the calculation of Net Income shall be determined in
      accordance with Section 4.6(b) and shall not include any items specially
      allocated under Section 5.1(d) or 5.1(e). Once an item of income, gain,
      loss or deduction that has been included in the initial computation of Net
      Income is subjected to a Required Allocation or a

                                      36

<Page>
      Discretionary Allocation, the applicable Net Income or Net Loss shall be
      recomputed without regard to such item. For purposes of Sections 5.1(a)
      and 5.1(b), in determining whether Net Income has been allocated to any
      Unit or any Partner (as the case may be) for any previous taxable period,
      any Unrealized Gain or Unrealized Loss allocated pursuant to Section
      4.6(d) shall be treated as an item of gain or loss in computing Net
      Income.

            (l) "NET LOSS" means, for any taxable period, the excess, if any, of
      the Partnership's items of loss and deduction (other than those items

      income and gain (other than those items attributable to dispositions
      constituting Termination Capital Transactions) for such taxable period.
      The items included in the calculation of Net Loss shall be determined in
      accordance with Section 4.6(b) and shall not include any items
      specifically allocated under Section 5.1(d) or 5.1(e). Once an item of
      income, gain, loss or deduction that has been included in the initial
      computation of Net Loss is subjected to a Required Allocation or a
      Discretionary Allocation, the applicable Net Income or Net Loss shall be
      recomputed without regard to such item. For purposes of Sections 5.1(a)
      and 5.1(b), in determining whether Net Losses have been allocated to any
      Unit or any Partner (as the case may be) for any previous taxable period,
      any Unrealized Gain or Unrealized Loss allocated pursuant to Section
      4.6(d) shall be treated as an item of gain or loss in computing Net
      Losses.

            (m) "NET TERMINATION GAIN" means the sum, if positive, of all items
      of income, gain, loss and deduction (as determined in accordance with

      Section 14.2 and all subsequent periods.

            (o) "SECOND TARGET DISTRIBUTION" means $0.99 per Unit per calendar
      quarter, subject to adjustment in accordance with Sections 5.9 and 9.6.

      5.9  ADJUSTMENT OF MINIMUM QUARTERLY DISTRIBUTION AND TARGET DISTRIBUTION
LEVELS.

            (a) Adjustments of the Minimum Quarterly Distribution, First Target
      Distribution and Second Target Distribution shall be made in the following
      circumstances: (i) the Minimum Quarterly Distribution, First Target
      Distribution and Second Target Distribution shall be proportionately
      adjusted in the event of any distribution, combination or subdivision
      (whether effected by a distribution payable in Units or otherwise) of
      Units or other Partnership Securities in accordance with Section 4.11;
      provided, however, that no such adjustment shall be made as a result of
      any increase in the number of I-Units or fractions of I-Units Outstanding
      pursuant to Section 5.10(a); and (ii) in the event of a distribution of
      Available Cash that is deemed to

                                      37

<Page>

      be Cash from Interim Capital Transactions, the Minimum Quarterly
      Distribution, First Target Distribution and Second Target Distribution
      shall be adjusted proportionately downward to equal the product obtained
      by multiplying the otherwise applicable Minimum Quarterly Distribution,
      First Target Distribution and Second Target Distribution, as the same may
      have been previously adjusted, by a fraction of which the numerator is the
      Unrecovered Initial Unit Price immediately after giving effect to such
      distribution and of which the denominator is the Unrecovered Initial Unit
      Price immediately prior to giving effect to such distribution.

            (b) The Minimum Quarterly Distribution, First Target Distribution
      and Second Target Distribution may also be adjusted under the
      circumstances, and in the manner, set forth in Section 9.6.

            5.10  SPECIAL PROVISIONS RELATING TO I-UNITS.

            (a) Except as otherwise provided by Sections 14.3(b) and 14.3(c),
      whenever distributions are made to Limited Partners holding Common Units
      pursuant to Sections 5.5 and 5.7, the number of Outstanding I-Units will
      be increased in accordance with paragraph (b) of this Section 5.10.
      Distributions pursuant to Sections 5.5 and 5.7 to Limited Partners holding
      Common Units and to the General Partner will be made in cash and an amount
      of Available Cash equal to the quotient obtained by dividing (i) the
      Equivalent Non-Cash Amount by (ii) .98 will be retained by the Partnership
      in respect of each I-Unit then Outstanding.

            (b) Whenever Limited Partners holding Common Units receive
      distributions of cash pursuant to Sections 5.5 and 5.7, the number of
      Outstanding I-Units will be automatically subdivided, by means of a split
      of each Outstanding I-Unit, or fraction thereof, with the result that each
      Limited Partner holding I-Units will own a number of additional fractional
      I-Units per each I-Unit, or fraction thereof, held by such Limited Partner
      immediately prior to the Record Date for the related cash distribution to
      Limited Partners holding Common Units, which number shall equal the
      Calculated Unit Amount. Each fractional I-Unit that is created pursuant to
      this Section 5.10(b) as a result of distributions of cash to Limited
      Partners holding Common Units pursuant to Sections 5.5 and 5.7 shall be
      equal to and represented by a fraction that is calculated to six decimal
      places (without rounding), and any calculation that would result in a
      fractional interest in excess of one-millionth (1/1,000,000) of an I-Unit
      shall be disregarded without payment or other consideration and shall not
      be accumulated. The creation of additional fractional I-Units pursuant to
      this Section 5.10(b) will not result in any adjustment to the Capital
      Accounts of holders of I-Units.

            (c) As used in this Agreement, (i) "EQUIVALENT NON-CASH AMOUNT"
      means, for each I-Unit, an amount equal to the cash distribution made on a
      Common Unit in accordance with Sections 5.5 and 5.7; (ii) "CALCULATED UNIT
      AMOUNT" means a fraction of an I-Unit calculated per I-Unit, or fraction
      thereof, by dividing the Equivalent Non-Cash Amount by the Average Market
      Price; and (iii) "AVERAGE MARKET PRICE" means the average of the daily
      Closing Prices per Listed Share for the ten consecutive Trading Days prior
      to the date on which the Listed Shares begin to trade ex-dividend, but not
      including

                                      38

<Page>

      that date. For purposes of this Section 5.10(c), the "date on which the
      Listed Shares begin to trade ex-dividend" means the date on which
      "ex-dividend" trading commences for a Share Distribution on the principal
      National Securities Exchange on which the Listed Shares are listed or
      admitted to trading.

            (d) At any time during which there are any I-Units Outstanding, the
      Partnership will not:

                  (i) make a distribution on a Common Unit other than in cash,
            Common Units or a Partnership Security that has in all material
            respects the same rights and privileges as the Common Units;

                  (ii) except pursuant to Section 14.3(b), make a distribution
            on an I-Unit other than in additional I-Units or a security that has
            in all material respects the same rights and privileges as the
            I-Units;

                  (iii) allow a Limited Partner holding Common Units to receive
            any consideration other than cash or Common Units or a security that
            has in all material respects the same rights and privileges as the
            Common Units or allow a Limited Partner holding I-Units to receive
            any consideration other than additional I-Units or a security that
            has in all material respects the same rights and privileges as the
            I-Units in a (A) merger, if the Limited Partners of the Partnership
            immediately prior to the transaction own more than 50% of the
            residual common equity securities of the survivor immediately after
            the transaction, or (B) recapitalization, reorganization or similar
            transaction;

                  (iv) be a party to a merger, sell substantially all of the
            Partnership's assets to another Person or enter into similar
            transactions if (A) the survivor of the merger or the other Person
            is to be an Affiliate of Enbridge Inc. after the transaction; and
            (B) the transaction will result in the occurrence of a Mandatory
            Purchase Event;

                  (v) make a tender offer for Common Units unless the
            consideration payable in such tender offer (A) is exclusively cash;
            and (B) together with any cash payable in respect of any other
            tender offer by the Partnership for Common Units concluded within
            the preceding 360 days and the aggregate amount of any cash
            distributions to all Limited Partners holding Common Units made
            within the preceding 360 days, is less than 12% of the aggregate
            market value of all Outstanding Units determined on the Trading Day
            immediately preceding the commencement of the tender offer;

                  (vi) issue any I-Units to any Person other than EEM; or

                  (vii) take any action that would result in the occurrence of a
            Special Event under clause (a) or (b) of the definition of "Special
            Event" in Section 1.01 of the Purchase Provisions, unless prior to
            the occurrence of such Special Event, the Purchaser has notified the
            Company and the Partnership that such Special Event shall constitute
            a Mandatory Purchase Event under the Purchase Provisions.

                                      39

            (e) In the event of any (i) consolidation or merger of the
      Partnership with or into another Person in accordance with Section 16.1
      (other than a consolidation or merger in which the Partnership is the
      Surviving Business Entity and which does not result in any
      reclassification, conversion, exchange or cancellation of Outstanding
      Common Units) or (ii) sale or other disposition to another Person of all
      or substantially all of the assets of the Partnership (any of the
      foregoing, a "TRANSACTION"), lawful provision shall be made such that if
      the Limited Partners holding Common Units receive cash in the Transaction,
      except as provided in Section 14.3(b), the number of Outstanding I-Units
      will be increased automatically by a split of each Outstanding I-Unit, or
      fraction thereof, so that the Limited Partners holding such Outstanding
      I-Unit, or fraction thereof, own, per Outstanding I-Unit, or fraction
      thereof, a number of additional I-Units or fractions of I-Units equal to
      the cash received on a Common Unit as a result of the Transaction divided
      by the average of the daily Closing Prices per Listed Share for the 10
      consecutive Trading Days immediately prior to the effective date of the
      Transaction.

                                   ARTICLE VI

      direct and exercise full control over all activities of the Partnership.
      Except as otherwise expressly provided in this Agreement, all management
      powers over the business and affairs of the Partnership shall be
      exclusively vested in the General Partner, and no Limited Partner or
      Assignee shall have any right of control or management power over the
      business and affairs of the Partnership. In addition to the powers now or
      hereafter granted to a general partner of a limited partnership under
      applicable law or which are granted to the General Partner under any other
      provision of this Agreement, the General Partner, subject to Section 6.3,
      shall have full power and authority to do all things and on such terms as
      it, in its sole discretion, may deem necessary or desirable (i) to conduct
      the business of the Partnership, to exercise all powers set forth in
      Section 3.2 and to effectuate the purposes set forth in Section 3.1,
      including, without limitation, (A) the making of any expenditures, the
      lending or borrowing of money, the assumption or guarantee of, or other
      contracting for, indebtedness and other liabilities, the issuance of
      evidences of indebtedness and the incurring of any other obligations and
      the securing of same by mortgage, deed of trust or other lien or
      encumbrance; (B) the making of tax, regulatory and other filings, or

      the Partnership, even if same results in the terms of the transaction
      being less favorable to the Partnership than would otherwise be the
      case); (F) the distribution of Partnership cash; (G) the selection and

      in, and the contributions of property to, any Operating Subsidiary from

      shareholder or other equity interest holder of any Operating General
      Partner (including, without limitation, contributions or loans of funds
      by the Partnership to any Operating Subsidiary).

            (b) Notwithstanding any other provision of this Agreement, any
      Operating Subsidiary Agreement, the Delaware Act or any applicable law,
      rule or regulation, each of the Partners and Assignees and each other

      and confirms the execution, delivery and performance by the parties
      thereto of the First Mortgage Note Agreements, the First Mortgage Notes,
      the related mortgage, the revolving credit facility, the Operating
      Partnership Agreement, the Underwriting Agreement, the Conveyance
      Agreement, the LPL Contribution Agreement, the Distribution Support
      Agreement (as each of the foregoing is defined or otherwise described in

      Partner is authorized to execute, deliver and perform the agreements
      referred to in clause (i) of this sentence and the other agreements, acts,
      transactions and matters described in the Registration Statement on behalf
      of the Partnership without any further act, approval or vote of the
      Partners or the Assignees or the other Persons who may acquire an interest
      in Units; and

                                      41

<Page>

      (iii) agrees that none of the execution, delivery or performance by the
      General Partner, the Partnership, any Operating Subsidiary or any
      Affiliate thereof of any agreement authorized or permitted under this
      Agreement (including, without limitation, the exercise by the General
      Partner or any Affiliate of the General Partner of the rights accorded
      pursuant to Article XVII) shall constitute a breach by the General
      Partner of any duty that the General Partner may owe the Partnership or
      the Limited Partners or the Assignees or any other Persons under this
      Agreement or of any duty stated or implied by law or equity.

            6.2  CERTIFICATE OF LIMITED PARTNERSHIP. The General Partner has
caused the Certificate of Limited Partnership to be filed with the Secretary of
State of the State of Delaware as required by the Delaware Act and shall use all
reasonable efforts to cause to be filed such other certificates or documents as
may be determined by the General Partner in its sole discretion to be reasonable
and necessary or appropriate for the formation, continuation, qualification and
operation of a limited partnership (or a partnership in which the limited
partners have limited liability) in the State of Delaware or any other state in
which the Partnership may elect to do business or own property. To the extent
that such action is determined by the General Partner in its sole discretion to
be reasonable and necessary or appropriate, the General Partner shall file
amendments to and restatements of the Certificate of Limited Partnership and do
all things to maintain the Partnership as a limited partnership (or a
partnership in which the limited partners have limited liability) under the laws
of the State of Delaware or of any other state in which the Partnership may
elect to do business or own property. Subject to the terms of Section 7.5(a),
the General Partner shall not be required, before or after filing, to deliver or
mail a copy of the Certificate of Limited Partnership, any qualification
document or any amendment thereto to any Limited Partner or Assignee.

            6.3  RESTRICTIONS ON GENERAL PARTNER'S AUTHORITY.

            (a) The General Partner may not, without written approval of the
      specific act by all of the Limited Partners or by other written instrument
      executed and delivered by all of the Limited Partners subsequent to the
      date of this Agreement, take any action in contravention of this
      Agreement, including, without limitation, (i) any act that would make it
      impossible to carry on the ordinary business of the Partnership, except as
      otherwise provided in this Agreement; (ii) possess Partnership property,
      or assign any rights in specific Partnership property, for other than a
      Partnership purpose; (iii) admit a Person as a Partner, except as
      otherwise provided in this Agreement; (iv) amend this Agreement in any
      manner, except as otherwise provided in this Agreement or applicable law;
      or (v) transfer its interest as general partner of the Partnership, except
      as otherwise provided in this Agreement.

            (b) Except as provided in Article XIV, the General Partner may not
      sell, exchange or otherwise dispose of all or substantially all of the
      Partnership's assets in a single transaction or a series of related
      transactions (including by way of merger, consolidation or other
      combination with any other Person) or approve on behalf of the Partnership
      the sale, exchange or other disposition of all or substantially all of the
      assets of Enbridge Energy, Limited Partnership, without the approval of
      the holders of at least a majority of the Outstanding Units; provided,
      however, that this provision shall not preclude or limit the General
      Partner's ability to mortgage, pledge, hypothecate or grant a

                                      42

<Page>

      security interest in all or substantially all of the Partnership's assets
      or any Operating Subsidiary's assets and shall not apply to any forced
      sale of any or all of the Partnership's assets or any Operating
      Subsidiary's assets pursuant to the foreclosure of, or other realization
      upon, any such encumbrance. Without the approval of the holders of at
      least a majority of the Outstanding Units, the General Partner shall not,
      on behalf of the Partnership, consent to any amendment to the partnership
      agreement of Enbridge Energy, Limited Partnership or, except as expressly
      permitted by Section 6.9(d), take any action permitted to be taken by the
      limited partner of Enbridge Energy, Limited Partnership, in either case,
      that would adversely affect the Partnership as a limited partner of
      Enbridge Energy, Limited Partnership.

            (c) Unless approved by the affirmative vote of the holders of at
      least 66-2/3% of each class of the Outstanding Units, the General Partner
      shall not take any action or refuse to take any reasonable action the
      effect of which, if taken or not taken, as the case may be, would be to
      cause the Partnership or any Operating Subsidiary to be taxable as a
      corporation or otherwise taxed as an entity for federal income tax
      purposes.

            (d) At all times while serving as the general partner of the
      Partnership, the General Partner shall not make any dividend or
      distribution on, or repurchase any shares of, its stock or take any other
      action within its control if the effect of such dividend, distribution,
      repurchase or other action would be to reduce its net worth below an
      amount necessary to receive an Opinion of Counsel that the Partnership
      will be treated as a partnership for federal income tax purposes.

            6.4  REIMBURSEMENT OF THE GENERAL PARTNER.

            (a) Except as provided in this Section 6.4 and elsewhere in this
      Agreement or in any Operating Subsidiary Agreement, the General Partner
      shall not be compensated for its services as general partner of the
      Partnership or on behalf of any Operating General Partner or any Operating
      Subsidiary.

            (b) The General Partner shall be reimbursed on a monthly basis, or
      such other basis as the General Partner may determine in its sole
      discretion, for (i) all direct and indirect expenses it incurs or payments
      it makes on behalf of the Partnership and any Operating Subsidiary
      (including, without limitation, amounts paid to any Person to perform
      services for the Partnership or for the benefit of the Partnership or to
      or on behalf of any Operating Subsidiary or Operating General Partner),
      and (ii) that portion of the General Partner's or its Affiliates' legal,
      accounting, investor communications, utilities, telephone, secretarial,
      travel, entertainment, bookkeeping, reporting, data processing, office
      rent and other office expenses (including, without limitation, overhead
      charges), salaries, fees and other compensation and benefit expenses of
      employees, officers and directors, insurance, other administrative or
      overhead expenses and all other expenses, in each such case, necessary or
      appropriate to the conduct of the Partnership's business and allocable to
      the Partnership or otherwise incurred by the General Partner in connection
      with operating the Partnership's business (including, without limitation,
      expenses allocated to the General Partner by its Affiliates). Any accruals
      by the General Partner of the expected cost of providing all forms of
      post-retirement benefits to employees or

                                      43

<Page>

      former employees of the General Partner and their beneficiaries and
      qualified dependents will be borne by the Partnership. The General
      Partner shall determine the fees and expenses that are allocable to the
      Partnership in any reasonable manner determined by the General Partner in
      its sole discretion. Such reimbursements shall be in addition to any
      reimbursement to the General Partner as a result of indemnification
      pursuant to Section 6.7.

            (c) Subject to Section 4.4(c), the General Partner in its sole
      discretion and without the approval of the Limited Partners may propose
      and adopt on behalf of the Partnership employee benefit plans (including,
      without limitation, plans involving the issuance of Units, other than
      I-Units), for the benefit of employees of the General Partner, any
      Operating General Partner, the Partnership, any Operating Subsidiary or
      any Affiliate of any of them in respect of services performed, directly or
      indirectly, for the benefit of the Partnership or any Operating
      Subsidiary.

            6.5  OUTSIDE ACTIVITIES.

            (a) After the date of this Agreement, the General Partner shall
      limit its activities to those required or authorized by this Agreement or
      the Omnibus Agreement.

            (b) Except as described in the Omnibus Agreement or as provided in
      Section 6.5(a), each Indemnitee is free to engage in any business,
      including any business that is in competition with the business of the
      Partnership. The General Partner and any other Persons affiliated with the
      General Partner may acquire Units or other Partnership Securities, in
      addition to those acquired by any of such Persons on the Closing Date, and
      shall be entitled to exercise all rights of an Assignee or Limited
      Partner, as applicable, relating to such Units or Partnership Securities,
      as the case may be.

            (c) Without limiting Sections 6.5(a) and 6.5(b), but notwithstanding
      anything to the contrary in this Agreement, the competitive activities of
      Indemnitees described in the Registration Statement are hereby approved by
      all Partners, and it shall not be deemed to be a breach of the General
      Partner's fiduciary duty for the General Partner to permit an Indemnitee
      to engage in a business opportunity in preference to or to the exclusion
      of the Partnership, provided such activities are not prohibited by the
      Omnibus Agreement.

            6.6  LOANS TO AND FROM THE GENERAL PARTNER; CONTRACTS WITH
AFFILIATES.

            (a) The General Partner or any Affiliate thereof may lend to the
      Partnership or any Operating General Partner or any Operating Subsidiary,
      and the Partnership and any Operating General Partner or any Operating
      Subsidiary may borrow, funds needed or desired by the Partnership and any
      Operating General Partner or any Operating Subsidiary for such periods of
      time as the General Partner may determine; provided, however, that the
      General Partner or any of its Affiliates may not charge the Partnership or
      any Operating General Partner or any Operating Subsidiary interest at a
      rate greater than the rate that would be charged the Partnership or any
      such Operating General Partner or Operating Subsidiary, as the case may be
      (without reference to the General Partner's

                                      44

<Page>

      financial abilities or guarantees), by unrelated lenders on comparable
      loans. The Partnership or any Operating General Partner or any Operating
      Subsidiary, as the case may be, shall reimburse the General Partner or any
      of its Affiliates, as the case may be, for any costs (other than any
      additional interest costs) incurred by it in connection with the borrowing
      of funds obtained by the General Partner or any of its Affiliates and
      loaned to the Partnership or any such Operating General Partner or
      Operating Subsidiary.

            (b) The Partnership may lend or contribute to any Operating General
      Partner or any Operating Subsidiary, and any Operating General Partner or
      any Operating Subsidiary may borrow, funds on terms and conditions
      established in the sole discretion of the General Partner. The foregoing
      authority shall be exercised by the General Partner in its sole discretion
      and shall not create any right or benefit in favor of any Operating
      General Partner or any Operating Subsidiary or any other Person. The
      Partnership may not lend funds to the General Partner or any of its
      Affiliates, otherwise than for short-term funds management purposes.

            (c) The General Partner may itself, or may enter into an agreement,
      including the Delegation of Control Agreement, with any of its Affiliates
      to, render services to the Partnership. Any service rendered to the
      Partnership by the General Partner or any of its Affiliates shall be on
      terms that are fair and reasonable to the Partnership; provided, however,
      that the requirements of this Section 6.6(c) shall be deemed satisfied as
      to any transaction the terms of which are no less favorable to the
      Partnership than those generally being provided to or available from
      unrelated third parties. The provisions of Section 6.4 shall apply to the
      rendering of services described in this Section 6.6(c).

            (d) The Partnership may transfer assets to joint ventures, other
      partnerships, corporations or other business entities in which it is or
      thereby becomes a participant upon such terms and subject to such
      conditions as are consistent with this Agreement and applicable law.

            (e) Neither the General Partner nor any of its Affiliates shall
      sell, transfer or convey any property to, or purchase any property from,
      the Partnership, directly or indirectly, except pursuant to transactions
      that are fair and reasonable to the Partnership; provided, however, that
      the requirements of this Section 6.6(e) shall be deemed to be satisfied
      (i) as to the transactions effected pursuant to Sections 4.2 and 4.3 of
      the Second Amended and Restated Agreement or any substantially similar
      provisions of any Prior Agreement, the Conveyance Agreement, and any other
      transactions described in or contemplated by the Registration Statement,
      and (ii) as to any transaction the terms of which are no less favorable to
      the Partnership than those generally being provided to or available from
      unrelated third parties.

            (f) The General Partner and its Affiliates shall have no obligation
      to permit the Partnership or any Operating Subsidiary to use any
      facilities of the General Partner and its Affiliates, except as may be
      provided in contracts entered into from time to time specifically dealing
      with such use, nor shall there be any obligation of the General Partner or
      its Affiliates to enter into such contracts.

            6.7  INDEMNIFICATION.

            (a) To the fullest extent permitted by law but subject to the
      limitations expressly provided in this Agreement, each Indemnitee shall be
      indemnified and held harmless by the Partnership from and against any and
      all losses, claims, damages, liabilities (joint or several), expenses
      (including, without limitation, legal fees and expenses), judgments,
      fines, settlements and other amounts arising from any and all claims,
      demands, actions, suits or proceedings, whether civil, criminal,
      administrative or investigative, in which any Indemnitee may be involved,
      or is threatened to be involved, as a party or otherwise, by reason of its
      status as (i) the General Partner, a Departing Partner or any of their
      Affiliates, (ii) an officer, director, employee, partner, agent or trustee
      of the General Partner, any Departing Partner or any of their Affiliates
      or (iii) a Person serving at the request of the Partnership in another
      entity in a similar capacity; provided, that in each case the Indemnitee
      acted in good faith, in a manner which such Indemnitee believed to be in,
      or not opposed to, the best interests of the Partnership and, with respect
      to any criminal proceeding, had no reasonable cause to believe its conduct
      was unlawful; provided, further, no indemnification pursuant to this
      Section 6.7 shall be available to the General Partner or Enbridge Inc.
      with respect to their respective obligations incurred pursuant to the
      Underwriting Agreement, the Conveyance Agreement or the Contribution
      Agreement (other than obligations incurred by the General Partner on
      behalf of the Partnership or any Operating Subsidiary). The termination of
      any action, suit or proceeding by judgment, order, settlement, conviction
      or upon a plea of nolo contendere, or its equivalent, shall not create a
      presumption that the Indemnitee acted in a manner contrary to that
      specified above. Any indemnification pursuant to this Section 6.7 shall be
      made only out of the assets of the Partnership.

            (b) To the fullest extent permitted by law, expenses (including,
      without limitation, reasonable legal fees and expenses) incurred by an
      Indemnitee in defending any claim, demand, action, suit or proceeding
      shall, from time to time, be advanced by the Partnership prior to the
      final disposition of such claim, demand, action, suit or proceeding upon
      receipt by the Partnership of an undertaking by or on behalf of the
      Indemnitee to repay such amount if it shall be determined that the
      Indemnitee is not entitled to be indemnified as authorized in this Section
      6.7.

            (c) The indemnification provided by this Section 6.7 shall be in
      addition to any other rights to which an Indemnitee may be entitled under
      any agreement, pursuant to any vote of the Partners, as a matter of law or
      otherwise, both as to actions in the Indemnitees' capacity as (i) the
      General Partner, a Departing Partner or an Affiliate thereof, (ii) an
      officer, director, employee, partner, agent or trustee of the General
      Partner, any Departing Partner or an Affiliate thereof or (iii) a Person
      serving at the request of the Partnership in another entity in a similar
      capacity, and shall continue as to an Indemnitee who has ceased to serve
      in such capacity and as to actions in any other capacity.

            (d) The Partnership may purchase and maintain (or reimburse the
      General Partner or its Affiliates for the cost of) insurance, on behalf of
      the General Partner and such other Persons as the General Partner shall
      determine, against any liability that may

                                      46

<Page>

      be asserted against or expense that may be incurred by such Person in
      connection with the Partnership's activities, whether or not the
      Partnership would have the power to indemnify such Person against such
      liabilities under the provisions of this Agreement.

            (e) For purposes of this Section 6.7, the Partnership shall be
      deemed to have requested an Indemnitee to serve as fiduciary of an
      employee benefit plan whenever the performance by it of its duties to the
      Partnership also imposes duties on, or otherwise involves services by, it
      to the plan or participants or beneficiaries of the plan; excise taxes
      assessed on an Indemnitee with respect to an employee benefit plan
      pursuant to applicable law shall constitute "fines" within the meaning of
      Section 6.7 (a); and action taken or omitted by it with respect to an
      employee benefit plan in the performance of its duties for a purpose
      reasonably believed by it to be in the interest of the participants and
      beneficiaries of the plan shall be deemed to be for a purpose which is in,
      or not opposed to, the best interests of the Partnership.

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

            (g) An Indemnitee shall not be denied indemnification in whole or in
      part under this Section 6.7 because the Indemnitee had an interest in the
      transaction with respect to which the indemnification applies if the
      transaction was otherwise permitted by the terms of this Agreement.

            (h) The provisions of this Section 6.7 are for the benefit of the
      Indemnitees, their heirs, successors, assigns and administrators and shall
      not be deemed to create any rights for the benefit of any other Persons.

            (i) No amendment, modification or repeal of this Section 6.7 or any
      other provision hereof shall in any manner terminate, reduce or impair the
      right of any past, present or future Indemnitee to be indemnified by the
      Partnership, nor the obligation of the Partnership to indemnify any such
      Indemnitee under and in accordance with the provisions of this Section 6.7
      as in effect immediately prior to such amendment, modification or repeal
      with respect to claims arising from or relating to matters occurring, in
      whole or in part, prior to such amendment, modification or repeal,
      regardless of when such claims may arise or be asserted.

            6.8  LIABILITY OF INDEMNITEES.

            (a) Notwithstanding anything to the contrary set forth in this
      Agreement, no Indemnitee shall be liable for monetary damages to the
      Partnership, the Limited Partners, the Assignees or any other Persons who
      have acquired interests in the Units, for losses sustained or liabilities
      incurred as a result of any act or omission if such Indemnitee acted in
      good faith.

            (b) Subject to its obligations and duties as General Partner set
      forth in Section 6.1(a), the General Partner may exercise any of the
      powers granted to it by this Agreement and perform any of the duties
      imposed upon it hereunder either directly or by or through its agents, and
      the General Partner shall not be responsible for any misconduct

                                      47

<Page>

      or negligence on the part of any such agent appointed by the General
      Partner in good faith. Notwithstanding the preceding sentence, the General
      Partner shall be responsible for any misconduct or negligence on the
      part of EEM in performing the Maximum Permitted Delegation.

            (c) Any amendment, modification or repeal of this Section 6.8 or any
      other provision hereof shall be prospective only and shall not in any way
      affect the limitations on the liability to the Partnership, the Limited
      Partners, the General Partner, and the Partnership's and General Partner's
      and any Operating General Partner's directors, officers and employees
      under this Section 6.8 as in effect immediately prior to such amendment,
      modification or repeal with respect to claims arising from or relating to
      matters occurring, in whole or in part, prior to such amendment,
      modification or repeal, regardless of when such claims may arise or be
      asserted.

            6.9  RESOLUTION OF CONFLICTS OF INTEREST.

            (a) Unless otherwise expressly provided in this Agreement or any
      Operating Subsidiary Agreement or the Omnibus Agreement, whenever a
      potential conflict of interest exists or arises between the General
      Partner or any of its Affiliates, on the one hand, and the Partnership,
      any Operating Subsidiary, any Partner or any Assignee, on the other hand,
      any resolution or course of action in respect of such conflict of interest
      shall be permitted and deemed approved by all Partners, and shall not
      constitute a breach of this Agreement, of any Operating Subsidiary
      Agreement, of any agreement contemplated herein or therein, or of any duty
      stated or implied by law or equity, if the resolution or course of action
      is or, by operation of this Agreement, is deemed to be, fair and
      reasonable to the Partnership. The General Partner shall be authorized in
      connection with its resolution of any conflict of interest to consider (i)
      the relative interests of any party to such conflict, agreement,
      transaction or situation and the benefits and burdens relating to such
      interest; (ii) any customary or accepted industry practices and any
      customary or historical dealings with a particular Person; (iii) any
      applicable generally accepted accounting or engineering practices or
      principles; and (iv) such additional factors as the General Partner
      determines in its sole discretion to be relevant, reasonable or
      appropriate under the circumstances. Nothing contained in this Agreement,
      however, is intended to nor shall it be construed to require the General
      Partner to consider the interests of any Person other than the
      Partnership. In the absence of bad faith by the General Partner, the
      resolution, action or terms so made, taken or provided by the General
      Partner with respect to such matter shall not constitute a breach of this
      Agreement or any other agreement contemplated herein or a breach of any
      standard of care or duty imposed herein or therein or under the Delaware
      Act or any other law, rule or regulation.

            (b) Whenever this Agreement or any other agreement contemplated
      hereby provides that the General Partner or any of its Affiliates is
      permitted or required to make a decision (i) in its "sole discretion" or
      "discretion" that it deems "necessary or appropriate" or under a grant of
      similar authority or latitude, the General Partner or such Affiliate shall
      be entitled to consider only such interests and factors as it desires and
      shall have no duty or obligation to give any consideration to any interest
      of, or factors affecting, the Partnership, any Operating Subsidiary, any
      Limited Partner or any

                                      48

<Page>

      Assignee, or (ii) in "good faith" or under another express standard, the
      General Partner or such Affiliate shall act under such express standard
      and shall not be subject to any other or different standards imposed by
      this Agreement, any Operating Subsidiary Agreement, any other agreement
      contemplated hereby or under the Delaware Act or any other law, rule or
      regulation. In addition, any actions taken by the General Partner
      consistent with the standards of "reasonable discretion" set forth in
      the definitions of Available Cash or Cash from Operations shall not
      constitute a breach of any duty of the General Partner to the Partnership
      or the Limited Partners. The General Partner shall have no duty, express
      or implied, to sell or otherwise dispose of any asset of any Operating
      Subsidiary or of the Partnership, other than in the ordinary course of
      business. No borrowing by the Partnership or any Operating Subsidiary
      or the approval thereof by the General Partner shall be deemed to
      constitute a breach of any duty of the General Partner to the Partnership
      or the Limited Partners by reason of the fact that the purpose or effect
      of such borrowing is directly or indirectly to enable the General Partner
      to receive incentive distributions.

            (c) Whenever a particular transaction, arrangement or resolution of
      a conflict of interest is required under this Agreement to be "fair and
      reasonable" to any Person, the fair and reasonable nature of such
      transaction, arrangement or resolution shall be considered in the context
      of all similar or related transactions.

            (d) The Limited Partners hereby authorize the General Partner, on
      behalf of the Partnership as a limited partner or member of any Operating
      Subsidiary, to approve actions by any Operating General Partner similar to
      those actions permitted to be taken by the General Partner pursuant to
      this Section 6.9.

            6.10  OTHER MATTERS CONCERNING THE GENERAL PARTNER.

            (a) The General Partner may rely and shall be protected in acting or
      refraining from acting upon any resolution, certificate, statement,
      instrument, opinion, report, notice, request, consent, order, bond,
      debenture, or other paper or document believed by it to be genuine and to
      have been signed or presented by the proper party or parties.

            (b) The General Partner may consult with legal counsel, accountants,
      appraisers, management consultants, investment bankers and other
      consultants and advisers selected by it, and any act taken or omitted in
      reliance upon the opinion (including, without limitation, an Opinion of
      Counsel) of such Persons as to matters that the General Partner reasonably
      believes to be within such Person's professional or expert competence
      shall be conclusively presumed to have been done or omitted in good faith
      and in accordance with such opinion.

            (c) The General Partner shall have the right, in respect of any of
      its powers or obligations hereunder, to act through any of its duly
      authorized officers and a duly appointed attorney or attorneys-in-fact.
      Each such attorney shall, to the extent provided by the General Partner in
      the power of attorney, have full power and authority to do and perform
      each and every act and duty that is permitted or required to be done by
      the General Partner hereunder.

                                      49

<Page>

            (d) Any standard of care and duty imposed by this Agreement or under
      the Delaware Act or any applicable law, rule or regulation shall be
      modified, waived or limited as required to permit the General Partner to
      act under this Agreement or any other agreement contemplated by this
      Agreement and to make any decision pursuant to the authority prescribed in
      this Agreement, so long as such action is reasonably believed by the
      General Partner to be in the best interests of the Partnership.

            6.11 TITLE TO PARTNERSHIP ASSETS. Title to Partnership Assets,
whether real, personal or mixed and whether tangible or intangible, shall be
deemed to be owned by the Partnership as an entity, and no Partner or
Assignee, individually or collectively, shall have any ownership interest in
such Partnership Assets or any portion thereof. Title to any or all of the
Partnership Assets may be held in the name of the Partnership, the General
Partner or one or more nominees, as the General Partner may determine. The
General Partner hereby declares and warrants that any Partnership Assets for
which record title is held in the name of the General Partner shall be held
by the General Partner for the exclusive use and benefit of the Partnership
in accordance with the provisions of this Agreement; provided, however, that
the General Partner shall use its reasonable efforts to cause record title to
such assets (other than those assets in respect of which the General Partner
determines that the expense and difficulty of conveyancing makes transfer of
record title to the Partnership impracticable) to be vested in the
Partnership as soon as reasonably practicable. All Partnership Assets shall
be recorded as the property of the Partnership in its books and records,
irrespective of the name in which record title to such Partnership assets are
held.

            6.12  PURCHASE OR SALE OF CLASS A COMMON UNITS. Subject to
Section 5.10(d)(v), the General Partner may cause the Partnership to purchase
or otherwise acquire Class A Common Units. As long as Class A Common Units
are held by the Partnership or any Operating Subsidiary, such Class A Common
Units shall not be considered Outstanding for any purpose, except as
otherwise provided herein. The General Partner or any Affiliate of the
General Partner may also purchase or otherwise acquire and sell or otherwise
dispose of Class A Common Units for its own account, subject to the
provisions of Articles XI and XII.

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

                                      50

<Page>

empowered to do so for and on behalf of the Partnership and (c) such
certificate, document or instrument was duly executed and delivered in
accordance with the terms and provisions of this Agreement and is binding
upon the Partnership.

            6.14  REGISTRATION RIGHTS OF THE GENERAL PARTNER AND ITS
AFFILIATES.

            (a) If (i) the General Partner or any of its Affiliates (including,
      for purposes of this Section 6.14, Persons that are Affiliates at the date
      hereof notwithstanding that they may later cease to be Affiliates) hold
      Units or other Partnership Securities which it desires to sell and (ii)
      Rule 144 of the Securities Act (or any successor rule or regulation to
      Rule 144) is not available to enable the General Partner or such
      Affiliates to dispose of the number of Units or other Partnership
      Securities it desires to sell at the time it desires to do so, then upon
      the request of the General Partner or any of its Affiliates, the
      Partnership shall file with the Securities and Exchange Commission as
      promptly as practicable after receiving such request, and use all
      reasonable efforts to cause to become effective and remain effective for a
      reasonable period following its effective date, a registration statement
      or statements under the Securities Act registering the offering and sale
      of the number of Units or other Partnership Securities specified in the
      request. All registrations requested pursuant to this Section 6.14(a) are
      referred to as "DEMAND REGISTRATIONS." The Partnership may postpone for up
      to six months the filing or the effectiveness of a registration statement
      pursuant to a Demand Registration if (i) the General Partner or, (ii) if
      at the time a request for Demand Registration is submitted to the
      Partnership the Person requesting registration is an Affiliate of the
      General Partner, a majority of the independent directors of the General
      Partner, determines in its good faith judgment that a postponement of the
      requested registration for up to six months would be in the best interests
      of the Partnership and its Partners due to a pending transaction,
      investigation or other event. In connection with any Demand Registration,
      the Partnership shall promptly prepare and file (x) such documents as may
      be necessary to register or qualify the securities subject to such
      registration under the securities laws of such states as the Persons
      requesting registration shall reasonably request; provided, however, that
      no such qualification shall be required in any jurisdiction where, as a
      result thereof, the Partnership would become subject to general service of
      process or to taxation or qualification to do business as a foreign
      corporation doing business in such jurisdiction, and (y) such documents as
      may be necessary to apply for listing or to list the securities subject to
      such registration on such National Securities Exchange as the Persons
      requesting registration shall reasonably request, and do any and all other
      acts and things that may reasonably be necessary or advisable to enable
      such Persons to consummate a public sale of such securities in such
      states. Except as set forth in subsection (c) below, all costs and
      expenses of any such Demand Registration and offering shall be paid by the
      Persons requesting registration, without reimbursement by the Partnership.

            (b) If the Partnership shall at any time propose to file a
      registration statement under the Securities Act for an offering of
      securities of the Partnership for cash (other than pursuant to a Demand
      Registration or an offering relating solely to an employee benefit plan),
      the Partnership shall use its best efforts to include such number or
      amount of securities held by the General Partner and any of its Affiliates
      in such registration

                                      51

<Page>

      statement as the General Partner or any of such Affiliates shall request.
      All registrations requested by the Purchaser pursuant to this Section
      6.14(b) are referred to herein as "PIGGYBACK REGISTRATIONS." If the
      proposed offering shall be an underwritten offering, then, in the event
      that the managing underwriter of such offering advises the General Partner
      or any of such Affiliates in writing that in its opinion the inclusion of
      all or some of the securities of the Persons requesting Piggyback
      Registration would adversely and materially affect the success of the
      offering, the Partnership shall include in such offering only that number
      or amount, if any, of securities of the Persons requesting Piggyback
      Registration which, in the opinion of the managing underwriter, will
      not so adversely and materially affect the offering. In connection with
      any Piggyback Registration, the General Partner or any of its Affiliates
      requesting registration shall bear the expense of all underwriting
      discounts and commissions attributable to the securities sold for their
      own respective accounts and shall reimburse the Partnership for all
      incremental costs incurred by the Partnership in connection with such
      registration resulting from the inclusion of the securities held by the
      General Partner or any of its Affiliates.

            (c) If underwriters are engaged in connection with any Demand or
      Piggyback Registration the Partnership shall provide indemnification,
      representations, covenants, opinions and other assurance to the
      underwriters in form and substance reasonably satisfactory to such
      underwriters. Further, in addition to and not in limitation of the
      Partnership's obligation under Section 6.7, the Partnership shall, to the
      fullest extent permitted by law, indemnify and hold harmless the General
      Partner or such other holder, its officers, directors and each Person who
      controls the General Partner or such other holder (within the meaning of
      the Securities Act) and any agent thereof (collectively, "INDEMNIFIED
      PERSONS") against any losses, claims, demands, actions, causes of action,
      assessments, damages, liabilities (joint or several), costs and expenses
      (including without limitation, interest, penalties and reasonable
      attorneys' fees and disbursements), resulting to, imposed upon, or
      incurred by an Indemnified Person, directly or indirectly, under the
      Securities Act or otherwise (hereinafter referred to in this Section
      6.14(c) as a "claim" and in the plural as "claims"), based upon, arising
      out of, or resulting from any untrue statement or alleged untrue statement
      of any material fact contained in any registration statement under which
      any securities were registered under the Securities Act or any state
      securities or Blue Sky laws, in any preliminary prospectus (if used prior
      to the effective date of such registration statement), or in any summary
      or final prospectus or in any amendment or supplement thereto (if used
      during the period the Partnership is required to keep the registration
      statement current), or arising out of, based upon or resulting from the
      omission or alleged omission to state therein a material fact required to
      be stated therein or necessary to make the statements made therein not
      misleading; provided, however, that the Partnership shall not be liable to
      the extent that any such claim arises out of, is based upon or results
      from an untrue statement or alleged untrue statement or omission or
      alleged omission made in such registration statement, such preliminary,
      summary or final prospectus or such amendment or supplement, in reliance
      upon and in conformity with written information furnished to the
      Partnership by or on behalf of such Indemnified Person specifically for
      use in the preparation thereof.

            (d) The provisions of Sections 6.14(a) and 6.14(b) shall continue to
      be applicable with respect to the General Partner and any of its
      Affiliates after the General

                                      52

<Page>

      Partner ceases to be a Partner of the Partnership, during a period of two
      years subsequent to the effective date of such cessation and for so long
      thereafter as is required for the General Partner or any of its Affiliates
      to sell all of the Units or other Partnership Securities with respect to
      which the General Partner or any of its Affiliates have requested during
      such two-year period that a registration statement be filed; provided,
      however, that the Partnership shall not be required to file successive
      registration statements covering the same securities for which
      registration was demanded during such two-year period. The provisions of
      Section 6.14(c) shall continue in effect thereafter.

            (e) Any request to register Partnership Securities pursuant to this
      Section 6.14 shall (i) specify the Partnership Securities intended to be
      offered and sold by the Person making the request, (ii) express such
      Person's present intent to offer such shares for distribution, (iii)
      describe the nature or method of the proposed offer and sale of
      Partnership Securities, and (iv) contain the undertaking of such Person to
      provide all such information and materials and take all action as may be
      required in order to permit the Partnership to comply with all applicable
      requirements in connection with the registration of such Partnership
      Securities.

            6.15  DELEGATION TO EEM.

            (a) Pursuant to Section 6.6(c) of this Agreement and in accordance
      with Section 17-403(c) of the Delaware Act, the General Partner shall
      delegate to EEM, to the fullest extent permitted under this Agreement and
      Delaware law, all of the General Partner's power and authority to manage
      and control the business and affairs of the Partnership under the terms
      and conditions of the Delegation of Control Agreement; provided, however,
      that such delegation shall not cause the General Partner to cease to be
      the sole general partner of the Partnership; and provided further, that
      the General Partner shall not be relieved of any of its responsibilities
      or obligations to the Partnership or the Limited Partners as a result of
      such delegation. The General Partner shall retain all of its Partnership
      Interest, Percentage Interest, rights to Incentive Distributions, rights
      to allocations of Net Income and Net Losses, rights to allocations of Net
      Termination Gains and Net Termination Losses, and rights to distributions
      pursuant to Sections 5.3, 5.5, 5.7 and 14.3. The specific terms and
      conditions of the delegation to EEM are set forth in the Delegation of
      Control Agreement.

            (b) Notwithstanding anything to the contrary set forth in this
      Agreement, and except to the extent otherwise provided in the Delegation
      of Control Agreement, until such date as the Maximum Permitted Delegation
      is terminated in accordance with the Delegation of Control Agreement, the
      provisions of this Agreement that apply to the management and control of
      the Partnership, including, without limitation, Sections 6.1, 6.3, 6.4,
      6.9, 6.10 and 6.14, shall apply to EEM to the same extent as such
      provisions apply to the General Partner.

            (c) Notwithstanding anything to the contrary set forth in this
      Agreement, the provisions of Section 6.7 of this Agreement shall apply to
      EEM and any Person who is or was a manager, officer or director of EEM to
      the same extent as such provisions apply to

                                      53

<Page>

      the General Partner and any Person who is or was an officer or director of
      the General Partner.

                                   ARTICLE VII
                 RIGHTS AND OBLIGATIONS OF LIMITED PARTNERS

            7.1  LIMITATION OF LIABILITY. The Limited Partners and the
Assignees shall have no liability under this Agreement except as expressly
provided in this Agreement or the Delaware Act.

            7.2  MANAGEMENT OF BUSINESS. No Limited Partner or Assignee
(other than the General Partner, any of its Affiliates or any officer,
director, employee, partner, agent or trustee of the General Partner or any
of its Affiliates, in its capacity as such, if such Person shall also be a
Limited Partner or Assignee) shall take part in the operation, management or
control (within the meaning of the Delaware Act) of the Partnership's
business, transact any business in the Partnership's name or have the power
to sign documents for or otherwise bind the Partnership. The transaction of
any such business by the General Partner, any of its Affiliates or any
officer, director, employee, partner, agent or trustee of the General Partner
or any of its Affiliates, in its capacity as such, shall not affect, impair
or eliminate the limitations on the liability of the Limited Partners or
Assignees under this Agreement.

            7.3  OUTSIDE ACTIVITIES. Subject to the provisions of Section
6.5, which shall continue to be applicable to the Persons referred to
therein, regardless of whether such Persons shall also be Limited Partners or
Assignees, any Limited Partner or Assignee shall be entitled to and may have
business interests and engage in business activities in addition to those
relating to the Partnership, including, without limitation, business
interests and activities in direct competition with the Partnership or any
Operating Subsidiary. Neither the Partnership nor any of the other Partners
or Assignees shall have any rights by virtue of this Agreement in any
business ventures of any Limited Partner or Assignee.

            7.4  RETURN OF CAPITAL. No Limited Partner shall be entitled to
the withdrawal or return of his Capital Contribution, except to the extent,
if any, that distributions made pursuant to this Agreement or upon
termination of the Partnership may be considered as such by law and then only
to the extent provided for in this Agreement. Except to the extent provided
by Article V or as otherwise expressly provided in this Agreement, no Limited
Partner or Assignee shall have priority over any other Limited Partner or
Assignee either as to the return of Capital Contributions or as to profits,
losses or distributions. Any such return shall be a compromise to which all
Partners and Assignees agree within the meaning of Section 17.502(b) of the
Delaware Act.

            7.5  RIGHTS OF LIMITED PARTNERS RELATING TO THE PARTNERSHIP.

            (a) In addition to other rights provided by this Agreement or by
      applicable law, and except as limited by Section 7.5(b), each Limited
      Partner shall have the right, for a purpose reasonably related to such
      Limited Partner's interest as a limited partner in the Partnership, upon
      reasonable demand and at such Limited Partner's own expense:

                                      54

<Page>

                  (i)  to obtain true and full information regarding the
            status of the business and financial condition of the
            Partnership;

                  (ii) promptly after becoming available, to obtain a copy of
            the Partnership's federal, state and local tax returns for each
            year;

                  (iii) to have furnished to him, upon notification to the
            General Partner, a current list of the name and last known business,
            residence or mailing address of each Partner;

                  (iv) to have furnished to him, upon notification to the
            General Partner, a copy of this Agreement and the Certificate of
            Limited Partnership and all amendments thereto;

                  (v) to obtain true and full information regarding the amount
            of cash and description and statement of the Agreed Value of any
            other Capital Contribution by each Partner and which each Partner
            has agreed to contribute in the future, and the date on which each
            became a Partner; and

                  (vi) to obtain such other information regarding the affairs of
            the Partnership as is just and reasonable.

            (b) Notwithstanding any other provision of this Agreement, the
      General Partner may keep confidential from the Limited Partners and
      Assignees for such period of time as the General Partner deems reasonable,
      any information that the General Partner reasonably believes to be in the
      nature of trade secrets or other information the disclosure of which the
      General Partner in good faith believes is not in the best interests of the
      Partnership or could damage the Partnership or any Operating Subsidiary or
      that the Partnership or any Operating Subsidiary is required by law or by
      agreements with third parties to keep confidential (other than agreements
      with Affiliates the primary purpose of which is to circumvent the
      obligations set forth in Section 7.5).

                                  ARTICLE VIII
                   BOOKS, RECORDS, ACCOUNTING AND REPORTS

            8.1  RECORDS AND ACCOUNTING. The General Partner shall keep or
cause to be kept at the principal office of the Partnership appropriate books
and records with respect to the Partnership's business including, without
limitation, all books and records necessary to provide to the Limited
Partners any information, lists and copies of documents required to be
provided pursuant to Section 7.5(a). Any books and records maintained by or
on behalf of the Partnership in the regular course of its business,
including, without limitation, the record of the Record Holders and Assignees
of Units or other Partnership Securities, books of account and records of
Partnership proceedings, may be kept on, or be in the form of, computer
disks, hard disks, punch cards, magnetic tape, photographs, micrographics or
any other information storage device, provided, that the books and records so
maintained are convertible into clearly legible written form within a
reasonable period of time. The books of the Partnership shall be maintained,
for financial reporting purposes, on an accrual basis in accordance with
generally accepted accounting principles.

            8.2 FISCAL YEAR.  The fiscal year of the Partnership shall be the
calendar year.

            8.3 REPORTS.

            (a) As soon as practicable, but in no event later than 120 days
      after the close of each Partnership Year, the General Partner shall cause
      to be mailed to each Record Holder of a Unit as of a date selected by the
      General Partner in its sole discretion, an annual report containing
      financial statements of the Partnership for such Partnership Year,
      presented in accordance with generally accepted accounting principles,
      including a balance sheet and statements of operations, Partners' equity
      and cash flows, such statements to be audited by a firm of independent
      public accountants selected by the General Partner.

            (b) As soon as practicable, but in no event later than 90 days after
      the close of each calendar quarter except the last calendar quarter of
      each year, the General Partner shall cause to be mailed to each Record
      Holder of a Unit, as of a date selected by the General Partner in its sole
      discretion, a report containing unaudited financial statements of the
      Partnership and such other information as may be required by applicable
      law, regulation or rule of any National Securities Exchange on which the
      Units are listed for trading, or as the General Partner determines to be
      necessary or appropriate.

                                   ARTICLE IX
                                   TAX MATTERS

            9.1 PREPARATION OF TAX RETURNS. The General Partner shall arrange
for the preparation and timely filing of all returns of Partnership income,
gains, deductions, losses and other items required of the Partnership for
federal and state income tax purposes and shall use all reasonable efforts to
furnish, within 90 days of the close of each taxable year of the Partnership,
the tax information reasonably required by Unitholders for federal and state
income tax reporting purposes. The classification, realization and
recognition of income, gain, losses and deductions and other items shall be
on the accrual method of accounting for federal income tax purposes. The
taxable year of the Partnership shall be the calendar year.

            9.2 TAX ELECTIONS. Except as otherwise provided herein, the
General Partner shall in its sole discretion, determine whether to make any
available election pursuant to the Code; provided, however, that the General
Partner shall make the election under Section 754 of the Code in accordance
with applicable regulations thereunder. The General Partner shall have the
right to seek to revoke any such election (including, without limitation, the
election under Section 754 of the Code) upon the General Partner's
determination in its sole discretion that such revocation is in the best
interests of the Limited Partners and Assignees.

            9.3 TAX CONTROVERSIES. Subject to the provisions hereof, the
General Partner is designated the Tax Matters Partner (as defined in Section
6231 of the Code), and is authorized and required to represent the
Partnership (at the Partnership's expense) in connection with all
examinations of the Partnership's affairs by tax authorities, including,
without limitation, resulting administrative and judicial proceedings, and to
expend Partnership funds for professional services and costs associated
therewith. Each Partner and Assignee agrees to

                                      56

<Page>

cooperate with the General Partner and to do or refrain from doing any or all
things reasonably required by the General Partner to conduct such proceedings.

            9.4 ORGANIZATIONAL EXPENSES. The Partnership shall elect to
deduct expenses, if any, incurred by it in organizing the Partnership ratably
over a 60-month period as provided in Section 709 of the Code.

            9.5 WITHHOLDING. Notwithstanding any other provision of this
Agreement, the General Partner is authorized to take any action that it
determines in its sole discretion to be necessary or appropriate to cause the
Partnership and any Operating Subsidiary to comply with any withholding
requirements established under the Code or any other federal, state or local
law, including, without limitation, pursuant to Sections 1441, 1442, 1445 and
1446 of the Code. To the extent that the Partnership is required to withhold
and pay over to any taxing authority any amount resulting from the allocation
or distribution of income to any Partner or Assignee (including, without
limitation, by reason of Section 1446 of the Code), the amount withheld shall
be treated as a distribution of cash for purposes of Section 4.6(a) in the
amount of such withholding from such Partner.

            9.6 ENTITY-LEVEL TAXATION. If legislation is enacted which causes
the Partnership to become treated as an association taxable as a corporation
for federal income tax purposes, then with respect to any calendar quarter
thereafter the Minimum Quarterly Distribution, First Target Distribution or
Second Target Distribution, as the case may be, shall be equal to the product
of (i) each such distribution amount multiplied by (ii) 1 minus the sum of
(x) the effective federal income tax rate applicable to the Partnership
(expressed as a percentage) plus (y) the effective overall state and local
income tax rate applicable to the Partnership (expressed as a percentage), in
each case, for the taxable year in which such quarter occurs (after taking
into account the benefit of any deduction allowable for federal income tax
purposes with respect to the payment of state and local income taxes).

            9.7 ENTITY-LEVEL DEFICIENCY COLLECTIONS. If the Partnership is
required by applicable law to pay any federal, state or local income tax on
behalf of, or withhold such amount with respect to, any Partner or Assignee
or any former Partner or Assignee (a) the General Partner shall cause the
Partnership to pay such tax on behalf of such Partner or Assignee or former
Partner or Assignee from the funds of the Partnership; (b) any amount so paid
on behalf of, or withheld with respect to, any Partner or Assignee shall be
treated as a distribution of cash to such Partner or Assignee for purposes of
Section 4.6(a); and (c) to the extent any such Partner or Assignee (but not a
former Partner or Assignee) is not then entitled to such distribution under
this Agreement, the General Partner shall be authorized, without the approval
of any Partner or Assignee, to amend this Agreement insofar as is necessary
to maintain the uniformity of intrinsic tax characteristics as to all Units
and to make subsequent adjustments to distributions in a manner which, in the
reasonable judgment of the General Partner, will make as little alteration as
practicable in the priority and amount of distributions otherwise applicable
under this Agreement, and will not otherwise alter the distributions to which
Partners and Assignees are entitled under this Agreement. If the Partnership
is permitted (but not required) by applicable law to pay any such tax on
behalf of any Partner or Assignee or former Partner or Assignee, the General
Partner shall be authorized (but not required) to cause the Partnership to
pay such tax from the funds of the Partnership and to take any action
consistent with this Section

                                      57

<Page>

9.7. The General Partner shall be authorized (but not required) to take all
necessary or appropriate actions to collect all or any portion of a
deficiency in the payment of any such tax that relates to prior periods and
that is attributable to Persons who were Limited Partners or Assignees when
such deficiencies arose, from such Persons.

            9.8 OPINIONS OF COUNSEL. Notwithstanding any other provision of
this Agreement, if the Partnership is taxable for federal income tax purposes
as a corporation or otherwise taxed for federal income tax purposes as an
entity at any time and, pursuant to the provisions of this Agreement, an
Opinion of Counsel would otherwise be required to the effect that an action
will not cause the Partnership to become so taxable as a corporation or other
entity or to be treated as an association taxable as a corporation, such
requirement for an Opinion of Counsel shall be deemed automatically waived.

                                    ARTICLE X
                                UNIT CERTIFICATES

            10.1 UNIT CERTIFICATES. Upon the Partnership's issuance of Common
Units to any Person, the Partnership shall issue one or more Certificates in
the name of such Person evidencing the number of such Units being so issued.
Certificates shall be executed on behalf of the Partnership by the General
Partner. No Class A Common Unit Certificate shall be valid for any purpose
until it has been countersigned by the Transfer Agent. Upon the Partnership's
issuance of I-Units to any Person, or upon an increase of the number of
Outstanding I-Units, the General Partner shall make an entry in the
Partnership's I-Unit register reflecting such issuance or increase, as the
case may be, but no Certificates evidencing the number of I-Units so issued
or increased, as the case may be shall be issued.

            10.2 REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE.

            (a) The General Partner shall cause to be kept on behalf of the
      Partnership a register (the "UNIT REGISTER") in which, subject to such
      reasonable regulations as it may prescribe and subject to the provisions
      of Section 10.2(b), the General Partner will provide for the registration
      and the transfer of Class A Common Units. The Transfer Agent is hereby
      appointed registrar and transfer agent for the purpose of registering and
      transferring Class A Common Units as herein provided. The Partnership
      shall not recognize transfers of Certificates representing Class A Common
      Units unless same are effected in the manner described in this Section
      10.2. Upon surrender for registration of transfer of any Units evidenced
      by a Certificate and subject to the provisions of Section 10.2(b), the
      General Partner on behalf of the Partnership will execute, and the
      Transfer Agent will countersign and deliver, in the name of the holder or
      the designated transferee or transferees, as required pursuant to the
      holder's instructions, one or more new Certificates evidencing the same
      aggregate number of Class A Common Units as was evidenced by the
      Certificate so surrendered.

            (b) Except as otherwise provided in Section 11.5, the Partnership
      shall not recognize any transfer of Class A Common Units until the
      Certificates evidencing such Units are surrendered for registration of
      transfer and such Certificates are accompanied by a Transfer Application
      duly executed by the transferee (or the transferee's attorney-in-

                                      58

<Page>

      fact duly authorized in writing). No charge shall be imposed by the
      Partnership for such transfer, provided, that, as a condition to the
      issuance of any new Certificate under this Section 10.2, the General
      Partner may require the payment of a sum sufficient to cover any tax or
      other governmental charge that may be imposed with respect thereto.

            10.3 MUTILATED, DESTROYED, LOST OR STOLEN CERTIFICATES.

            (a) If any mutilated Certificate is surrendered to the Transfer
      Agent, the General Partner on behalf of the Partnership shall execute,
      and, upon its request, the Transfer Agent shall countersign and deliver in
      exchange therefor, a new Certificate evidencing the same number of Units
      as the Certificate so surrendered.

            (b) The General Partner on behalf of the Partnership shall execute,
      and, upon its request, the Transfer Agent shall countersign and deliver a
      new Certificate in place of any Certificate previously issued if the
      Record Holder of the Certificate:

                  (i) makes proof by affidavit, in form and substance
            satisfactory to the General Partner, that a previously issued
            Certificate has been lost, destroyed or stolen;

                  (ii) requests the issuance of a new Certificate before the
            Partnership has received notice that the Certificate has been
            acquired by a purchaser for value in good faith and without notice
            of an adverse claim;

                  (iii) if requested by the General Partner, delivers to the
            Partnership such security or indemnity as may be required by the
            General Partner, in form and substance satisfactory to the General
            Partner, with surety or sureties and with fixed or open penalty as
            the General Partner may direct, in its sole discretion, to indemnify
            the Partnership, the General Partner and the Transfer Agent against
            any claim that may be made on account of the alleged loss,
            destruction or theft of the Certificate; and

                  (iv) satisfies any other reasonable requirements imposed
            by the General Partner.

If a Limited Partner or Assignee fails to notify the Partnership within a
reasonable time after he has notice of the loss, destruction or theft of a
Certificate, and a transfer of the Units represented by the Certificate is
registered before the Partnership, the General Partner or the Transfer Agent
receives such notification, the Limited Partner or Assignee shall be precluded
from making any claim against the Partnership, the General Partner or the
Transfer Agent for such transfer or for a new Certificate.

            (c) As a condition to the issuance of any Certificate under this
      Section 10.3, the General Partner may require the payment of a sum
      sufficient to cover any tax or other governmental charge that may be
      imposed in relation thereto and any other expenses (including, without
      limitation, the fees and expenses of the Transfer Agent) connected
      therewith.

                                      59

<Page>

            10.4 RECORD HOLDER. In accordance with Section 10.2(b), the
Partnership shall be entitled to recognize the Record Holder as the
Limited Partner or Assignee with respect to any Units and, accordingly,
shall not be bound to recognize any equitable or other claim to or
interest in such Units on the part of any other Person, whether or not
the Partnership shall have actual or other notice thereof, except as
otherwise provided by law or any applicable rule, regulation, guideline
or requirement of any National Securities Exchange on which the Units
are listed for trading. Without limiting the foregoing, when a Person
(such as a broker, dealer, bank, trust company or clearing corporation
or an agent of any of the foregoing) is acting as nominee, agent or in
some other representative capacity for another Person in acquiring
and/or holding Units, as between the Partnership on the one hand and
such other Persons on the other hand, such representative Person (a)
shall be the Limited Partner or Assignee (as the case may be) of record
and beneficially, (b) must execute and deliver a Transfer Application
and (c) shall be bound by this Agreement and shall have the rights and
obligations of a Limited Partner or Assignee (as the case may be)
hereunder and as provided for herein.

                                  ARTICLE XI
                            TRANSFER OF INTERESTS

            11.1 TRANSFER.

            (a) The term "transfer," when used in this Article XI with respect
      to a Partnership Interest, shall be deemed to refer to an appropriate
      transaction by which the General Partner assigns its Partnership Interest
      as General Partner to another Person or by which the holder of a Unit
      assigns such Unit to another Person who is or becomes an Assignee and
      includes a sale, assignment, gift, pledge, encumbrance, hypothecation,
      mortgage, exchange or any other disposition by law or otherwise.

            (b) No Partnership Interest shall be transferred, in whole or in
      part, except in accordance with the terms and conditions set forth in this
      Article XI. Any transfer or purported transfer of a Partnership Interest
      not made in accordance with this Article XI shall be null and void.

            11.2 TRANSFER OF GENERAL PARTNER'S PARTNERSHIP INTEREST.

            (a) The General Partner may transfer all, but not less than all, of
      its Partnership Interest as the General Partner to a single transferee if,
      but only if, (i) at least 66 2/3% of the Outstanding Units (excluding for
      purposes of such determination any Common Units held by the General
      Partner and its Affiliates and the number of I-Units that equal the number
      of Listed Shares and Voting Shares owned by the General Partner and its
      Affiliates) and a majority of the Outstanding I-Units voting as a separate
      class (excluding for purposes of such determination the number of I-Units
      that equal the number of Listed Shares and Voting Shares owned by the
      General Partner and its Affiliates) approve of such transfer and of the
      admission of such transferee as General Partner, (ii) the transferee
      agrees to assume the rights and duties of the General Partner and be bound
      by the provisions of this Agreement and (iii) the Partnership receives an
      Opinion of Counsel that such transfer would not result in the loss of
      limited liability of any Limited Partner or of any limited partner or
      member of any Operating Subsidiary or

                                      60

<Page>

      cause the Partnership or any Operating Subsidiary to be taxable as a
      corporation or otherwise taxed as an entity for federal income tax
      purposes.

            (b) Neither Section 11.2(a) nor any other provision of this
      Agreement shall be construed to prevent (and all Partners do hereby
      consent to) (i) the transfer by the General Partner of all of its
      Partnership Interest as a General Partner to an Affiliate or (ii) the
      transfer by the General Partner of all its Partnership Interest as a
      General Partner upon its merger or consolidation with or other combination
      into any other Person or the transfer by it of all or substantially all of
      its assets to another Person if, in the case of a transfer described in
      either clause (i) or (ii) of this sentence, the rights and duties of the
      General Partner with respect to the Partnership Interest so transferred
      are assumed by the transferee and the transferee agrees to be bound by the
      provisions of this Agreement; provided, that, in either such case, such
      transferee furnishes to the Partnership an Opinion of Counsel that such
      merger, consolidation, combination, transfer or assumption will not result
      in a loss of limited liability of any Limited Partner or of any limited
      partner or member of any Operating Subsidiary or cause the Partnership or
      any Operating Subsidiary to be taxable as a corporation or otherwise taxed
      as an entity for federal income tax purposes. In the case of a transfer
      pursuant to this Section 11.2(b), the transferee or successor (as the case
      may be) shall be admitted to the Partnership as the General Partner
      immediately prior to the transfer of the Partnership Interest, and the
      business of the Partnership shall continue without dissolution.

            11.3 TRANSFER OF UNITS.

            (a) Units may be transferred only in the manner described in Section
      10.2. The transfer of any Units and the admission of any new Partner shall
      not constitute an amendment to this Agreement.

            (b) Until admitted as a Substituted Limited Partner pursuant to
      Article XII, the Record Holder of a Unit shall be an Assignee in respect
      of such Unit. Limited Partners may include custodians, nominees or any
      other individual or entity in its own or any representative capacity.

            (c) Each distribution in respect of Units shall be paid by the
      Partnership, directly or through the Transfer Agent or through any other
      Person or agent, only to the Record Holders thereof as of the Record Date
      set for the distribution. Such payment shall constitute full payment and
      satisfaction of the Partnership's liability in respect of such payment,
      regardless of any claim of any Person who may have an interest in such
      payment by reason of an assignment or otherwise.

            (d) A transferee who has completed and delivered a Transfer
      Application shall be deemed to have (i) requested admission as a
      Substituted Limited Partner, (ii) agreed to comply with and be bound by
      and to have executed this Agreement, (iii) represented and warranted that
      such transferee has the capacity and authority to enter into this
      Agreement, (iv) made the powers of attorney set forth in this Agreement
      and (v) given the consents and made the waivers contained in this
      Agreement.

                                      61

<Page>

            11.4 RESTRICTIONS ON TRANSFERS. Notwithstanding the other
provisions of this Article XI, no transfer of any Unit or interest
therein of any Limited Partner or Assignee shall be made if such
transfer would (a) violate the then applicable federal or state
securities laws or rules and regulations of the Securities and Exchange
Commission, any state securities commission or any other governmental
authorities with jurisdiction over such transfer, (b) cause the
Partnership to be taxable as a corporation or otherwise taxed as an
entity for federal income tax purposes or (c) affect the Partnership's
existence or qualification as a limited partnership under the Delaware
Act.

            11.5 CITIZENSHIP CERTIFICATES; NON-CITIZEN ASSIGNEES.

            (a) If the Partnership or any Operating Subsidiary is or becomes
      subject to any federal, state or local law or regulation which, in the
      reasonable determination of the General Partner, provides for the
      cancellation or forfeiture of any property in which the Partnership or any
      Operating Subsidiary has an interest based on the nationality, citizenship
      or other status of a Limited Partner or Assignee, the General Partner may
      request any Limited Partner or Assignee to furnish to the General Partner,
      within 30 days after receipt of such request, an executed Citizenship
      Certification or such other information concerning his nationality,
      citizenship or other status (or, if the Limited Partner or Assignee is a
      nominee holding for the account of another Person, the nationality,
      citizenship or other status of such Person) as the General Partner may
      request. If a Limited Partner or Assignee fails to furnish to the General
      Partner within the aforementioned 30-day period such Citizenship
      Certification or other requested information or if upon receipt of such
      Citizenship Certification or other requested information the General
      Partner determines, with the advice of counsel, that a Limited Partner or
      Assignee is not an Eligible Citizen, the Units owned by such Limited
      Partner or Assignee shall be subject to redemption in accordance with the
      provisions of Section 11.6. In addition, the General Partner may require
      that the status of any such Limited Partner or Assignee be changed to that
      of a Non-citizen Assignee, and, thereupon, the General Partner shall be
      substituted for such Non-citizen Assignee as the Limited Partner in
      respect of his Units.

            (b) The General Partner shall, in exercising voting rights in
      respect of Units held by it on behalf of Non-citizen Assignees, distribute
      the votes in the same ratios as the votes of Limited Partners in respect
      of Units of the same class other than those of Non-citizen Assignees are
      cast, either for, against or abstaining as to the matter.

            (c) Upon dissolution of the Partnership, a Non-citizen Assignee
      shall have no right to receive a distribution in kind pursuant to Section
      14.4 but shall be entitled to the cash equivalent thereof, and the General
      Partner shall provide cash in exchange for an assignment of the
      Non-citizen Assignee's share of the distribution in kind. Such payment and
      assignment shall be treated for Partnership purposes as a purchase by the
      General Partner from the Non-citizen Assignee of his Partnership Interest
      (representing his right to receive his share of such distribution in
      kind).

            (d) At any time after he can and does certify that he has become an
      Eligible Citizen, a Non-citizen Assignee may, upon application to the
      General Partner, request

                                      62

<Page>

      admission as a Substituted Limited Partner with respect to any Units of
      such Non-citizen Assignee not redeemed pursuant to Section 11.6, and
      upon the Non-citizen Assignee's admission pursuant to Section 12.2 the
      General Partner shall cease to be deemed to be the Limited Partner in
      respect of the Non-citizen Assignee's Units.

            11.6 REDEMPTION OF INTERESTS.

            (a) If at any time a Limited Partner or Assignee fails to furnish a
      Citizenship Certification or other information requested within the 30-day
      period specified in Section 11.5(a), or if upon receipt of such
      Citizenship Certification or other information the General Partner
      determines, with the advice of counsel, that a Limited Partner or Assignee
      is not an Eligible Citizen, the Partnership may, unless the Limited
      Partner or Assignee establishes to the satisfaction of the General Partner
      that such Limited Partner or Assignee is an Eligible Citizen or has
      transferred his Units to a Person who furnishes a Citizenship
      Certification to the General Partner prior to the date fixed for
      redemption as provided below, redeem the Partnership Interest of such
      Limited Partner or Assignee as follows:

                  (i) The General Partner shall, not later than the 30th day
            before the date fixed for redemption, give notice of redemption to
            the Limited Partner or Assignee, at his last address designated on
            the records of the Partnership or the Transfer Agent, by registered
            or certified mail, postage prepaid. The notice shall be deemed to
            have been given when so mailed. The notice shall specify the
            Redeemable Units, the date fixed for redemption, the place of
            payment, that payment of the redemption price will be made upon
            surrender of the Certificate evidencing the Redeemable Units and
            that on and after the date fixed for redemption no further
            allocations or distributions to which the Limited Partner or
            Assignee would otherwise be entitled in respect of the Redeemable
            Units will accrue or be made.

                  (ii) The aggregate redemption price for Redeemable Units shall
            be an amount equal to the Current Market Price (the date of
            determination of which shall be the date fixed for redemption) of
            Units of the class to be so redeemed multiplied by the number of
            Units of each such class included among the Redeemable Units. The
            redemption price shall be paid, in the sole discretion of the
            General Partner, in cash or by delivery of a promissory note of the
            Partnership in the principal amount of the redemption price, bearing
            interest at the rate of 10% annually and payable in three equal
            annual installments of principal together with accrued interest,
            commencing one year after the redemption date.

                  (iii) Upon surrender by or on behalf of the Limited Partner or
            Assignee, at the place specified in the notice of redemption, of the
            Certificate evidencing the Redeemable Units, duly endorsed in blank
            or accompanied by an assignment duly executed in blank, the Limited
            Partner or Assignee or his duly authorized representative shall be
            entitled to receive the payment therefor.

                  (iv) After the redemption date, Redeemable Units shall no
            longer constitute issued and Outstanding Units.

            (b) The provisions of this Section 11.6 shall also be applicable to
      Units held by a Limited Partner or Assignee as nominee of a Person
      determined to be other than an Eligible Citizen.

            (c) Nothing in this Section 11.6 shall prevent the recipient of a
      notice of redemption from transferring his Units before the redemption
      date if such transfer is otherwise permitted under this Agreement. Upon
      receipt of notice of such a transfer, the General Partner shall withdraw
      the notice of redemption, provided, the transferee of such Units certifies
      in the Transfer Application that he is an Eligible Citizen. If the
      transferee fails to make such certification, such redemption shall be
      effected from the transferee on the original redemption date.

            (d) If the Partnership is or becomes subject to any federal, state
      or local law or regulation which, in the reasonable determination of the
      General Partner, provides for the cancellation or forfeiture of any
      property in which the Partnership or any Operating Subsidiary has an
      interest, based on the nationality (or other status) of the General
      Partner, whether or not in its capacity as such, the Partnership may,
      unless the General Partner has furnished a Citizenship Certification or
      transferred its Partnership Interest or Units to a Person who furnishes a
      Citizenship Certification prior to the date fixed for redemption, redeem
      the Partnership Interest or Interests of the General Partner in the
      Partnership, which redemption shall also constitute redemption of the
      general partner interest of the general partner of any Operating
      Subsidiary. If such redemption includes a redemption of the Combined
      Interest, the redemption price thereof shall be equal to the aggregate sum
      of the Current Market Price (the date of determination for which shall be
      the date fixed for redemption) of each class of Units then Outstanding, in
      each such case multiplied by the number of Units of such class into which
      the Combined Interest would then be convertible under the terms of Section
      13.3(b) if the General Partner were to withdraw or be removed as the
      General Partner (the date of determination for which shall be the date
      fixed for redemption). The redemption price shall be paid in cash or by
      delivery of a promissory note of the Partnership in the principal amount
      of the redemption price, bearing interest at the rate of 10% annually and
      payable in three equal annual installments of principal, together with
      accrued interest, commencing one year after the redemption date.

                                   ARTICLE XII
                              ADMISSION OF PARTNERS

            12.1 INTENTIONALLY OMITTED.

            12.2 ADMISSION OF SUBSTITUTED LIMITED PARTNERS. By transfer
of a Unit in accordance with Article XI, the transferor shall be deemed
to have given the transferee the right to seek admission as a
Substituted Limited Partner subject to the conditions of, and in the
manner permitted under, this Agreement. A transferor of a Certificate
shall, however, only have the authority to convey to a purchaser or
other transferee who does not execute and deliver a

                                      64

<Page>

Transfer Application (i) the right to negotiate such Certificate to a
purchaser or other transferee and (ii) the right to transfer the right to
request admission as a Substituted Limited Partner to such purchaser or other
transferee in respect of the transferred Units. Each transferee of a Unit
(including, without limitation, any nominee holder or an agent acquiring such
Unit for the account of another Person) who executes and delivers a Transfer
Application shall, by virtue of such execution and delivery, be an Assignee
and be deemed to have applied to become a Substituted Limited Partner with
respect to the Units so transferred to such Person. Such Assignee shall
become a Substituted Limited Partner (i) at such time as the General Partner
consents thereto, which consent may be given or withheld in the General
Partner's sole discretion, and (ii) when any such admission is shown on the
books and records of the Partnership. If such consent is withheld, such
transferee shall be an Assignee. An Assignee shall have an interest in the
Partnership equivalent to that of a Limited Partner with respect to
allocations and distributions, including, without limitation, liquidating
distributions, of the Partnership. With respect to voting rights attributable
to Units that are held by Assignees, the General Partner shall be deemed to
be the Limited Partner with respect thereto and shall, in exercising the
voting rights in respect of such Units on any matter, vote such Units at the
written direction of the Assignee who is the Record Holder of such Units. If
no such written direction is received, such Units will not be voted. An
Assignee shall have no other rights of a Limited Partner.

            12.3 ADMISSION OF SUCCESSOR GENERAL PARTNER. A successor General
Partner approved pursuant to Section 13.1 or the transferee of or successor
to all of the General Partner's Partnership Interest pursuant to Section 11.2
who is proposed to be admitted as a successor General Partner shall be
admitted to the Partnership as the General Partner, effective immediately
prior to the withdrawal or removal of the General Partner pursuant to Section
13.1 or the transfer of the General Partner's Partnership Interest pursuant
to Section 11.2; provided, however, that no such successor shall be admitted
to the Partnership until such successor has complied with the terms of
Sections 11.2(a)(ii) and (a)(iii). Any such successor shall carry on the
business of the Partnership without dissolution. In each case, the admission
shall be subject to the successor General Partner executing and delivering to
the Partnership an acceptance of all of the terms and conditions of this
Agreement and such other documents or instruments as may be required to
effect the admission.

            12.4 ADMISSION OF ADDITIONAL LIMITED PARTNERS.

            (a) A Person (other than the General Partner or a Substituted
      Limited Partner) who makes a Capital Contribution to the Partnership in
      accordance with this Agreement shall be admitted to the Partnership as an
      Additional Limited Partner only upon furnishing to the General Partner (i)
      evidence of acceptance in form satisfactory to the General Partner of all
      of the terms and conditions of this Agreement, including, without
      limitation, the power of attorney granted in Section 1.4, and (ii) such
      other documents or instruments as may be required in the discretion of the
      General Partner to effect such Person's admission as an Additional Limited
      Partner.

            (b) Notwithstanding anything to the contrary in this Section 12.4,
      no Person shall be admitted as an Additional Limited Partner without the
      consent of the General Partner, which consent may be given or withheld in
      the General Partner's sole discretion.

                                      65

<Page>

      The admission of any Person as an Additional Limited Partner shall
      become effective on the date upon which the name of such Person is
      recorded on the books and records of the Partnership, following the
      consent of the General Partner to such admission.

            12.5 AMENDMENT OF AGREEMENT AND CERTIFICATE OF LIMITED
PARTNERSHIP. To effect the admission to the Partnership of any Partner,
the General Partner shall take all steps necessary and appropriate under
the Delaware Act to amend the records of the Partnership and, if
necessary, to prepare as soon as practical an amendment of this
Agreement and, if required by law, to prepare and file an amendment to
the Certificate of Limited Partnership and may for this purpose, among
others, exercise the power of attorney granted pursuant to Section 1.4.

                                  ARTICLE XIII
                        WITHDRAWAL OR REMOVAL OF PARTNERS

            13.1 WITHDRAWAL OF THE GENERAL PARTNER.

            (a) The General Partner shall be deemed to have withdrawn from the
      Partnership upon the occurrence of any one of the following events (each
      such event herein referred to as an "EVENT OF WITHDRAWAL"):

                  (i)  the General Partner voluntarily withdraws from the
            Partnership by giving written notice to the other Partners;

                  (ii) the General Partner transfers all of its rights as
            General Partner pursuant to Section 11.2;

                  (iii) the General Partner is removed pursuant to Section
            13.2;

                  (iv) the General Partner (A) makes a general assignment for
            the benefit of creditors; (B) files a voluntary bankruptcy petition;
            (C) files a petition or answer seeking for itself a reorganization,
            arrangement, composition, readjustment, liquidation, dissolution or
            similar relief under any law; (D) files an answer or other pleading
            admitting or failing to contest the material allegations of a
            petition filed against the General Partner in a proceeding of the
            type described in clauses (A)-(C) of this sentence; or (E) seeks,
            consents to or acquiesces in the appointment of a trustee, receiver
            or liquidator of the General Partner or of all or any substantial
            part of its properties;

                  (v) a final and non-appealable judgment is entered by a court
            with appropriate jurisdiction ruling that the General Partner is
            bankrupt or insolvent, or a final and non-appealable order for
            relief is entered by a court with appropriate jurisdiction against
            the General Partner, in each case under any federal or state
            bankruptcy or insolvency laws as now or hereafter in effect; or

                  (vi) a certificate of dissolution or its equivalent is filed
            for the General Partner, or 90 days expire after the date of notice
            to the General Partner of revocation of its charter without a
            reinstatement of its charter, under the laws of its state of
            incorporation.

                                      66

<Page>

      In no event shall the Maximum Permitted Delegation pursuant to the terms
and conditions of the Delegation of Control Agreement and this Agreement be
deemed an Event of Withdrawal.

      If an Event of Withdrawal specified in this Section 13.1(a)(iv), (v) or
(vi) occurs, the withdrawing General Partner shall give written notice to the
Limited Partners within 30 days after such occurrence. The Partners hereby agree
that only the Events of Withdrawal described in this Section 13.1 shall result
in the withdrawal of the General Partner from the Partnership.

            (b) Withdrawal of the General Partner from the Partnership upon the
      occurrence of an Event of Withdrawal will not constitute a breach of this
      Agreement under the following circumstances: (i) at any time that the
      General Partner voluntarily withdraws by giving at least 90 days' advance
      notice to the Limited Partners, such withdrawal to take effect on the date
      specified in such notice; or (ii) at any time that the General Partner
      ceases to be a General Partner pursuant to Section 13.1(a)(ii) or is
      removed pursuant to Section 13.2. If the General Partner gives a notice of
      withdrawal pursuant to Section 13.1(a)(i), holders of at least a majority
      of the Outstanding Units (excluding for purposes of such determination
      Common Units owned by the General Partner and its Affiliates and the
      number of I-Units that equal the number of Listed Shares and Voting Shares
      owned by the General Partner and its Affiliates) may, prior to the
      effective date of such withdrawal, elect a successor General Partner. If,
      prior to the effective date of the General Partner's withdrawal, a
      successor is not selected by the Limited Partners as provided herein or
      the Partnership does not receive an Opinion of Counsel that following the
      election of a successor General Partner, the General Partner's withdrawal
      would not result in the loss of limited liability of any Limited Partner
      or of any limited partner or member of any Operating Subsidiary or cause
      the Partnership or any Operating Subsidiary to be taxable as a corporation
      or otherwise taxed as an entity for federal tax purposes (a "WITHDRAWAL
      OPINION OF COUNSEL"), the Partnership shall be dissolved in accordance
      with Section 14.1. If a successor General Partner is elected and a
      Withdrawal Opinion of Counsel is rendered, such successor shall be
      admitted (subject to Section 12.3) immediately prior to the effective time
      of the withdrawal or removal of the Departing Partner and shall continue
      the business of the Partnership without dissolution.

            13.2 REMOVAL OF THE GENERAL PARTNER. The General Partner may
be removed with or without Cause if such removal is approved by at least
66 2/3% of the Outstanding Common Units voting as a separate class
(excluding for purposes of such determination Common Units held by the
General Partner and its Affiliates) and a majority of the Outstanding
I-Units voting as a separate class (excluding for purposes of such
determination the number of I-Units that equal the number of Listed
Shares and Voting Shares owned by the General Partner and its
Affiliates). Any such action by the Limited Partners for removal of the
General Partner must also provide for the election and succession of a
new General Partner. Such removal shall be effective immediately
following the admission of the successor General Partner pursuant to
Article XII. The right of the Limited Partners to remove the General
Partner shall not exist or be exercised unless the Partnership has
received an Opinion of Counsel opining as to the matters covered by a
Withdrawal Opinion of Counsel.

            13.3 INTEREST OF DEPARTING PARTNER AND SUCCESSOR GENERAL PARTNER.

            (a) In the event of (i) withdrawal of the General Partner under
      circumstances where such withdrawal does not violate this Agreement or
      (ii) removal of the General Partner by the Limited Partners under
      circumstances where Cause does not exist, the Departing Partner shall, at
      its option exercisable prior to the effective date of the departure of
      such Departing Partner, promptly receive from its successor in exchange
      for its Partnership Interest as General Partner an amount in cash equal to
      the fair market value of the Departing Partner's Partnership Interest as
      General Partner, such amount to be determined and payable as of the
      effective date of its departure. If the General Partner withdraws under
      circumstances where such withdrawal violates this Agreement or if the
      General Partner is removed by the Limited Partners under circumstances
      where Cause exists, the General Partner's successor shall have the option
      described in the immediately preceding sentence, and the Departing Partner
      shall not have such option. In either event, the Departing Partner shall
      be entitled to receive all reimbursements due such Departing Partner
      pursuant to Section 6.4, including, without limitation, any
      employee-related liabilities (including, without limitation, severance
      liabilities), incurred in connection with the termination of any employees
      employed by the General Partner for the benefit of the Partnership or any
      Operating Subsidiary. Subject to Section 13.3(b), the Departing Partner
      shall, as of the effective date of its departure, cease to share in any
      allocations or distributions with respect to its Partnership Interest as
      the General Partner and Partnership income, gain, loss, deduction and
      credit will be prorated and allocated as set forth in Section 5.2(g).

      For purposes of this Section 13.3(a), the fair market value of the
Departing Partner's Partnership Interest as the general partner of the
Partnership herein (the "DEPARTING INTEREST") shall be determined by agreement
between the Departing Partner and its successor or, failing agreement within 30
days after the effective date of such Departing Partner's departure, by an
independent investment banking firm or other independent expert selected by the
Departing Partner and its successor, which, in turn, may rely on other experts
and the determination of which shall be conclusive as to such matter. If such
parties cannot agree upon one independent investment banking firm or other
independent expert within 45 days after the effective date of such departure,
then the Departing Partner shall designate an independent investment banking
firm or other independent expert, the Departing Partner's successor shall
designate an independent investment banking firm or other independent expert,
and such firms or experts shall mutually select a third independent investment
banking firm or independent expert, which shall determine the fair market value
of the Departing Interest. In making its determination, such independent
investment banking firm or other independent expert shall consider the then
current trading price of Units on any National Securities Exchange on which
Units are then listed, the value of the Partnership's assets, the rights and
obligations of the General Partner and other factors it may deem relevant.

            (b) If the Departing Interest is not acquired in the manner set
      forth in Section 13.3(a), the Departing Partner shall become a Limited
      Partner and the Departing Interest shall be converted into Class A Common
      Units pursuant to a valuation made by an investment banking firm or other
      independent expert selected pursuant to Section 13.3(a), without reduction
      in such Partnership Interest (but subject to proportionate dilution by

                                      68

<Page>

      reason of the admission of its successor). Any successor General Partner
      shall indemnify the Departing Partner as to all debts and liabilities of
      the Partnership arising on or after the date on which the Departing
      Partner becomes a Limited Partner. For purposes of this Agreement,
      conversion of the General Partner's Partnership Interest to Class A Common
      Units will be characterized as if the General Partner contributed its
      Partnership Interest to the Partnership in exchange for the newly-issued
      Class A Common Units.

            (c) If the option described in Section 13.3(a) is not exercised by
      the party entitled to do so, the successor General Partner shall, at the
      effective date of its admission to the Partnership, contribute to the
      capital of the Partnership cash in an amount such that its Capital
      Account, after giving effect to such contribution and any adjustments made
      to the Capital Accounts of all Partners pursuant to Section 4.6(d)(i),
      shall be equal to that percentage of the Capital Accounts of all Partners
      that is equal to its Percentage Interest as the General Partner. In such
      event, each successor General Partner shall, subject to the following
      sentence, be entitled to such Percentage Interest of all Partnership
      allocations and distributions and any other allocations and distributions
      to which the Departing Partner was entitled. In addition, such successor
      General Partner shall cause this Agreement to be amended to reflect that,
      from and after the date of such successor General Partner's admission, the
      successor General Partner's interest in all Partnership distributions and
      allocations shall be 2%, and that of the holders of Outstanding Units
      shall be 98%.

            13.4 [INTENTIONALLY OMITTED].

            13.5 WITHDRAWAL OF LIMITED PARTNERS. No Limited Partner
shall have any right to withdraw from the Partnership; provided,
however, that when a transferee of a Limited Partner's Units becomes a
Record Holder, such transferring Limited Partner shall cease to be a
Limited Partner with respect to the Units so transferred.

                                   ARTICLE XIV
                           DISSOLUTION AND LIQUIDATION

            14.1 DISSOLUTION. The Partnership shall not be dissolved by
the admission of Substituted Limited Partners or Additional Limited
Partners or by the admission of a successor General Partner in
accordance with the terms of this Agreement. Upon the removal or
withdrawal of the General Partner, any successor General Partner shall
continue the business of the Partnership. The Partnership shall
dissolve, and its affairs should be wound up, upon:

            (a) the expiration of its term as provided in Section 1.5;

            (b) an Event of Withdrawal of the General Partner as provided in
      Section 13.1 (a), unless a successor is named as provided in Section
      13.1(b) or Section 13.2, as the case may be;

            (c) an election to dissolve the Partnership by the General
      Partner that is approved by at least 66 2/3% of the Outstanding Units
      (and all Limited Partners hereby expressly consent that such
      approval may be effected upon written consent of at least 66 2/3% of
      the Outstanding Units);

                                      69

<Page>

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

            (e) the sale of all or substantially all of the assets and
      properties of the Partnership or Enbridge Energy, Limited
      Partnership.

            14.2 CONTINUATION OF THE BUSINESS OF THE PARTNERSHIP AFTER
DISSOLUTION. Upon (i) dissolution of the Partnership following an Event
of Withdrawal caused by the withdrawal or removal of the General Partner
and a failure of the requisite number of Partners to appoint a successor
General Partner as provided in Section 13.1 or 13.2, as the case may be,
then within an additional 90 days or (ii) dissolution of the Partnership
upon an event constituting an Event of Withdrawal described in Section
13.1(a)(iv), then within 180 days thereafter, at least a majority of the
Outstanding Units may elect to reconstitute the Partnership and continue
its business on the same terms and conditions set forth in this
Agreement by forming a new limited partnership on terms identical to
those set forth in this Agreement and having as a general partner a
Person approved by the holders of at least a majority of the Outstanding
Units. Upon any such election by the holders of at least a majority of
the outstanding Units, all Partners shall be bound thereby and shall be
deemed to have approved thereof. Unless such an election is made with
the applicable time period as set forth above, the Partnership shall
conduct only activities necessary to wind up its affairs. If such an
election is so made, then:

            (a) the reconstituted Partnership shall continue until the end of
      the term set forth in Section 1.5 unless earlier dissolved in accordance
      with this Article XIV;

            (b) if the successor General Partner is not the former General
      Partner, then the interest of the former General Partner shall be treated
      thenceforth as the interest of a Limited Partner and converted into Class
      A Common Units in the manner provided in Section 13.3(b); and

            (c) all necessary steps shall be taken to cancel this Agreement and
      the Certificate of Limited Partnership and to enter into and, as
      necessary, to file a new partnership agreement and certificate of limited
      partnership, and the successor general partner may for this purpose
      exercise the powers of attorney granted the General Partner pursuant to
      Section 1.4; provided that the right of at least a majority of Outstanding
      Units to approve a successor general partner and to reconstitute and to
      continue the business of the Partnership shall not exist and may not be
      exercised unless the Partnership has received an Opinion of Counsel that
      (x) the exercise of the right would not result in the loss of limited
      liability of any Limited Partner and (y) neither the Partnership, the
      reconstituted limited partnership nor any Operating Subsidiary would
      become taxable as a corporation or otherwise be taxed as an entity for
      federal income tax purposes upon the exercise of such right to continue.

            14.3 LIQUIDATION. Upon dissolution of the Partnership,
unless the Partnership is continued under an election to reconstitute
and continue the Partnership pursuant to Section 14.2, the General
Partner, or in the event the General Partner has been dissolved or
removed, become bankrupt as set forth in Section 13.1 or withdrawn from
the Partnership, a liquidator or liquidating committee approved by at
least 66 2/3% of the Outstanding Units, shall be the

                                      70

<Page>

Liquidator. The Liquidator (if other than the General Partner) shall be
entitled to receive such compensation for its services as may be
approved by at least 66 2/3% of the Outstanding Units. The Liquidator
shall agree not to resign at any time without 15 days' prior written
notice and (if other than the General Partner) may be removed at any
time, with or without Cause by notice of removal approved by at least 66
2/3% of the Outstanding Units. Upon dissolution, removal or resignation
of the Liquidator, a successor and substitute Liquidator (who shall have
and succeed to all rights, powers and duties of the original Liquidator)
shall within 30 days thereafter be approved by at least 66 2/3% of the
Outstanding Units. The right to approve a successor or substitute
Liquidator in the manner provided herein shall be deemed to refer also
to any such successor or substitute Liquidator approved in the manner
herein provided. Except as expressly provided in this Article XIV, the
Liquidator approved in the manner provided herein shall have and may
exercise, without further authorization or consent of any of the parties
hereto, all of the powers conferred upon the General Partner under the
terms of this Agreement (but subject to all of the applicable
limitations, contractual and otherwise, upon the exercise of such
powers, other than the limitation on sale set forth in Section 6.3(b))
to the extent necessary or desirable in the good faith judgment of the
Liquidator to carry out the duties and functions of the Liquidator
hereunder for and during such period of time as shall be reasonably
required in the good faith judgment of the Liquidator to complete the
winding up and liquidation of the Partnership as provided for herein.
The Liquidator shall liquidate the assets of the Partnership, and apply
and distribute the proceeds of such liquidation in the following order
of priority, unless otherwise required by mandatory provisions of
applicable law:

            (a) the payment to creditors of the Partnership, including, without
      limitation, Partners who are creditors, in the order of priority provided
      by law; and the creation of a reserve of cash or other assets of the
      Partnership for contingent liabilities in an amount, if any, determined by
      the Liquidator to be appropriate for such purposes;

            (b) to all Partners in accordance with the positive balances in
      their respective Capital Accounts after taking into account adjustments to
      such Capital Accounts pursuant to Section 5.1(c);

            (c) to all Partners in accordance with their respective
      Percentage Interests.

            14.4 DISTRIBUTIONS IN KIND. Notwithstanding the provisions
of Section 14.3, which require the liquidation of the assets of the
Partnership, but subject to the order of priorities set forth therein,
if prior to or upon dissolution of the Partnership the Liquidator
determines that an immediate sale of part or all of the Partnership's
assets would be impractical or would cause undue loss to the Partners,
the Liquidator may, in its absolute discretion, defer for a reasonable
time the liquidation of any assets except those necessary to satisfy
liabilities of the Partnership (including, without limitation, those to
Partners as creditors) or distribute to the Partners, in lieu of cash,
as tenants in common and in accordance with the provisions of Section
14.3, undivided interests in such Partnership assets as the Liquidator
deems not suitable for liquidation. Any such distributions in kind shall
be made only if, in the good faith judgment of the Liquidator, such
distributions in kind are in the best interest of the Limited Partners,
and shall be subject to such conditions relating to the disposition and
management of such properties as the Liquidator deems reasonable and
equitable and to any agreement governing the operation of such
properties at such time. The Liquidator shall determine the fair market
value of any property distributed in

                                      71

<Page>

kind using such reasonable method of valuation as it may adopt.
Notwithstanding the foregoing, the Liquidator may not make distributions in
kind unless all of the Listed Shares are owned by the General Partner and its
Affiliates.

            14.5 CANCELLATION OF CERTIFICATE OF LIMITED PARTNERSHIP. Upon the
completion of the distribution of Partnership cash and property as provided
in Sections 14.3 and 14.4, the Partnership shall be terminated and the
Certificate of Limited Partnership and all qualifications of the Partnership
as a foreign limited partnership in jurisdictions other than the State of
Delaware shall be canceled and such other actions as may be necessary to
terminate the Partnership shall be taken.

            14.6 REASONABLE TIME FOR WINDING UP. A reasonable time shall be
allowed for the orderly winding up of business and affairs of the Partnership
and the liquidation of its assets pursuant to Section 14.3 in order to
minimize any losses otherwise attendant upon such winding up, and the
provisions of this Agreement shall remain in effect between the Partners
during the period of liquidation.

            14.7 RETURN OF CAPITAL. The General Partner shall not be
personally liable for the return of the Capital Contributions of the Limited
Partners, or any portion thereof, it being expressly understood that any such
return shall be made solely from Partnership assets.

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

            14.9 WAIVER OF PARTITION.  Each Partner hereby waives any right
to partition of the Partnership property.

         AMENDMENT OF PARTNERSHIP AGREEMENT; MEETINGS; RECORD DATE

            15.1 AMENDMENT TO BE ADOPTED SOLELY BY GENERAL PARTNER. Each

any Limited Partner or Assignee, may amend any provision of this Agreement,
and execute, swear to, acknowledge, deliver, file and record whatever
documents may be required in connection therewith, to reflect:

                                      72
<Page>

            (c) a change that, in the sole discretion of the General Partner, is
      reasonable and necessary or appropriate to qualify or continue the
      qualification of the Partnership as a limited partnership or a partnership
      in which the limited partners have limited liability under the laws of any
      state or that is necessary or advisable in the opinion of the General
      Partner to ensure that the Partnership will not be taxable as a
      corporation or otherwise taxed as an entity for federal income tax
      purposes;

            (d) a change (i) that, in the sole discretion of the General
      Partner, does not adversely affect the Limited Partners in any material

      federal or state agency or judicial authority or contained in any federal
      or state statute (including, without limitation, the Delaware Act) or that
      is necessary or appropriate to facilitate the trading of the Units
      (including, without limitation, the division of Outstanding Units into
      different classes to facilitate uniformity of tax consequences within such
      classes of Units) or comply with any rule, regulation, interpretative
      release, guideline or requirement of any National Securities Exchange on
      which the Units are or will be listed for trading, compliance with any of
      which the General Partner determines in its sole discretion to be in the
      best interests of the Partnership and the Limited Partners or (iii) that
      is required to effect the intent of the provisions of this Agreement or is
      otherwise contemplated by this Agreement;

            (e) an amendment that is necessary, in the Opinion of Counsel, to
      prevent the Partnership or the General Partner or its directors or
      officers from in any manner being subjected to the provisions of the
      Investment Company Act of 1940, as amended, the Investment Advisers Act of
      1940, as amended, or "plan asset" regulations adopted under the Employee
      Retirement Income Security Act of 1974, as amended, whether or not
      substantially similar to plan asset regulations currently applied or
      proposed by the United States Department of Labor;

            (f) subject to the terms of Section 4.4, an amendment that the
      General Partner determines in its sole discretion to be necessary or
      appropriate in connection with the authorization for issuance of any class
      or series of Units pursuant to Section 4.4;

            (g)   Intentionally Omitted;

            (h)   Intentionally Omitted;

            (i)   any amendment expressly permitted in this Agreement to
      be made by the General Partner acting alone;

            (j)   an amendment effected, necessitated or contemplated by a
      Merger Agreement approved in accordance with Section 16.3; or

            (k)   any other amendments substantially similar to the
      foregoing.

<Page>

            15.2  AMENDMENT PROCEDURES.

            (a) Except as provided in Sections 15.1 and 15.3, all amendments to
      this Agreement shall be made in accordance with the following
      requirements. Amendments to this Agreement may be proposed solely by the
      General Partner. Each such proposal shall contain the text of the proposed
      amendment. If an amendment is proposed, the General Partner shall seek the
      written approval of the requisite percentage of Outstanding Units or call
      a meeting of the Limited Partners to consider and vote on such proposed
      amendment. A proposed amendment shall be effective upon its approval by
      the holders of at least 66 2/3% of the Outstanding Units unless a greater
      or different percentage is required under this Agreement; provided that,
      in addition to such approval, if the effect of any amendment would have a
      material adverse effect, as determined in the sole discretion of the
      General Partner, on the rights or preferences of any class of Outstanding
      Units in relation to any other class of Outstanding Units, the approval of
      the holders of at least a majority of the Outstanding Units of the class
      so affected, voting separately as a class, shall be required to adopt such
      amendment (excluding for purposes of such determination, in the case of a
      vote of the Record Holders of I-Units, the number of I-Units that equal
      the number of Listed Shares and Voting Shares owned by the General Partner
      and its Affiliates). The General Partner shall notify all Record Holders
      upon final adoption of any proposed amendment.

            (b) In addition to any other vote that may be required under the
      terms of this Agreement, and without limitation of the General Partner's
      authority to adopt amendments to this Agreement as contemplated in Section
      15.1, any amendments to Section 5.10(d) shall require the approval of a
      majority of the Outstanding I-Units, voting as a separate class (excluding
      for purposes of such determination the number of I-Units that equals the
      number of Listed Shares and Voting Shares owned by the General Partner and
      its Affiliates).

            15.3  AMENDMENT REQUIREMENTS.

            (a) Notwithstanding the provisions of Sections 15.1 and 15.2, no
      provision of this Agreement that establishes a percentage of Outstanding
      Units required to take any action shall be amended, altered, changed,
      repealed or rescinded in any respect that would have the effect of
      reducing such voting requirement unless such amendment is approved by the
      written consent or the affirmative vote of Unitholders whose aggregate
      percentage of Outstanding Units constitutes not less than the required
      percentage of Outstanding Units sought to be reduced.

            (b) Notwithstanding the provisions of Sections 15.1 and 15.2, no
      amendment to this Agreement may (i) enlarge the obligations of any Limited
      Partner without such Limited Partner's consent, which may be given or
      withheld in its sole discretion, (ii) modify the amounts distributable to
      the General Partner in respect of its general partner interest in the
      Partnership or any Operating Subsidiary or modify the amounts reimbursable
      or otherwise payable to the General Partner or any of its Affiliates by
      the Partnership, (iii) change Section 14.1(a) or (c), (iv) restrict in any
      way any action by or rights of the General Partner as set forth in this
      Agreement without the General Partner's

                                       74
<Page>

      consent (which may be given or withheld in the sole discretion of the
      General Partner) or (v) change the term of the Partnership or, except
      as set forth in Section 14.1(c), give any Person the right to dissolve
      the Partnership.

            (c) Except as otherwise provided, and without limitation of the
      General Partner's authority to adopt amendments to this Agreement as
      contemplated in Section 15.1, the General Partner may amend the
      Partnership Agreement without the approval of Unitholders, except that any
      amendment that would have a material adverse effect on the holders of any
      type or class of Outstanding Units must be approved by the holders of not
      less than 66 2/3% of the Outstanding Units of such type or class.

            (d) Notwithstanding any other provision of this Agreement, except
      for amendments pursuant to Section 6.3 or 15.1, no amendments shall become
      effective without the approval of the Record Holders of at least 95% of
      the Units unless the Partnership obtains an Opinion of Counsel to the
      effect that (a) such amendment will not cause the Partnership or any
      Operating Subsidiary to be taxable as a corporation or otherwise taxed as
      an entity for federal income tax purposes and (b) such amendment will not
      affect the limited liability of any Limited Partner or any limited partner
      of Enbridge Energy, Limited Partnership under applicable law.

            (e) This Section 15.3 shall only be amended with the approval of the
      Record Holders of not less than 95% of the Outstanding Units.

            15.4  MEETINGS. All acts of Limited Partners to be taken
hereunder shall be taken in the manner provided in this Article XV. Meetings
of the Limited Partners may be called by the General Partner or by Limited
Partners owning 20% or more of the Outstanding Units of the class for which a
meeting is proposed. Limited Partners shall call a meeting by delivering to
the General Partner one or more requests in writing stating that the signing
Limited Partners wish to call a meeting and indicating the general or
specific purposes for which the meeting is to be called. Within 60 days after
receipt of such a call from Limited Partners or within such greater time as
may be reasonably necessary for the Partnership to comply with any statutes,
rules, regulations, listing agreements or similar requirements governing the
holding of a meeting or the solicitation of proxies for use at such a
meeting, the General Partner shall send a notice of the meeting to the
Limited Partners either directly or indirectly through the Transfer Agent. A
meeting shall be held at a time and place determined by the General Partner
on a date not more than 60 days after the mailing of notice of the meeting.
Limited Partners shall not vote on matters that would cause the Limited
Partners to be deemed to be taking part in the management and control of the
business and affairs of the Partnership so as to jeopardize the Limited
Partners' limited liability under the Delaware Act or the law of any other
state in which the Partnership is qualified to do business.

            15.5  NOTICE OF A MEETING. Notice of a meeting called pursuant to
Section 15.4 shall be given to the Record Holders in writing by mail or other
means of written communication in accordance with Section 18.1. The notice
shall be deemed to have been given at the time when deposited in the mail or
sent by other means of written communication.

                                       75
<Page>

            15.6  RECORD DATE. For purposes of determining the Limited
Partners entitled to notice of or to vote at a meeting of the Limited
Partners or to give approvals without a meeting as provided in Section 15.11,
the General Partner may set a Record Date, which shall not be less than 10
nor more than 60 days before (a) the date of the meeting (unless such
requirement conflicts with any rule, regulation, guideline or requirement of
any National Securities Exchange on which the Units are listed for trading,
in which case the rule, regulation, guideline or requirement of such exchange
shall govern) or (b) in the event that approvals are sought without a
meeting, the date by which Limited Partners are requested in writing by the
General Partner to give such approvals.

            15.7  ADJOURNMENT. When a meeting is adjourned to another time or
place, notice need not be given of the adjourned meeting and a new Record
Date need not be fixed, if the time and place thereof are announced at the
meeting at which the adjournment is taken, unless such adjournment shall be
for more than 45 days. At the adjourned meeting, the Partnership may transact
any business which might have been transacted at the original meeting. If the
adjournment is for more than 45 days or if a new Record Date is fixed for the
adjourned meeting, a notice of the adjourned meeting shall be given in
accordance with this Article XV.

            15.8  WAIVER OF NOTICE; APPROVAL OF MEETING; APPROVAL OF MINUTES.
The transactions of any meeting of Limited Partners, however called and
noticed, and whenever held, shall be as valid as if had at a meeting duly
held after regular call and notice, if a quorum is present either in person
or by proxy, and if, either before or after the meeting, each of the Limited
Partners entitled to vote, present in person or by proxy, signs a written
waiver of notice or an approval of the holding of the meeting or an approval
of the minutes thereof. All waivers and approvals shall be filed with the
Partnership records or made a part of the minutes of the meeting. Attendance
of a Limited Partner at a meeting shall constitute a waiver of notice of the
meeting, except when the Limited Partner disapproves, at the beginning of the
meeting, the transaction of any business because the meeting is not lawfully
called or convened, and except that attendance at a meeting is not a waiver
of any right to disapprove the consideration of matters required to be
included in the notice of the meeting, but not so included, in either case if
the disapproval is expressly made at the meeting.

            15.9  QUORUM. The holders of 66 2/3% of the Outstanding Units of
the class for which a meeting has been called represented in person or by
proxy shall constitute a quorum at a meeting of Limited Partners of such
class unless any such action by the Limited Partners requires approval by
holders of a majority in interest of such Units, in which case the quorum
shall be a majority. At any meeting of the Limited Partners duly called and
held in accordance with this Agreement at which a quorum is present, the act
of Limited Partners holding Outstanding Units that in the aggregate represent
at least 66 2/3% of the Outstanding Units entitled to vote and be present in
person or by proxy at such meeting shall be deemed to constitute the act of
all Limited Partners, unless a greater or different percentage is required
with respect to such action under the provisions of this Agreement, in which
case the act of the Limited Partners holding Outstanding Units that in the
aggregate represent at least such greater or different percentage shall be
required. The Limited Partners present at a duly called or held meeting at
which a quorum is present may continue to transact business until
adjournment, notwithstanding the withdrawal of enough Limited Partners to
leave less than a quorum, if any action taken (other than adjournment) is
approved by the required percentage of Outstanding Units specified in this

                                       76

<Page>

Agreement. In the absence of a quorum, any meeting of Limited Partners may be
adjourned from time to time by the affirmative vote of a majority of the
Outstanding Units represented either in person or by proxy, but no other
business may be transacted, except as provided in Section 15.7.

            15.10 CONDUCT OF MEETING. The General Partner shall have full
power and authority concerning the manner of conducting any meeting of the
Limited Partners or solicitation of approvals in writing, including, without
limitation, the determination of Persons entitled to vote, the existence of a
quorum, the satisfaction of the requirements of Section 15.4, the conduct of
voting, the validity and effect of any proxies and the determination of any
controversies, votes or challenges arising in connection with or during the
meeting or voting. The General Partner shall designate a Person to serve as
chairman of any meeting and shall further designate a Person to take the
minutes of any meeting, in either case including, without limitation, a
Partner or a director or officer of the General Partner. All minutes shall be
kept with the records of the Partnership maintained by the General Partner.
The General Partner may make such other regulations consistent with
applicable law and this Agreement as it may deem advisable concerning the
conduct of any meeting of the Limited Partners or solicitation of approvals
in writing, including, without limitation, regulations in regard to the
appointment of proxies, the appointment and duties of inspectors of votes and
approvals, the submission and examination of proxies and other evidence of
the right to vote, and the revocation of approvals in writing.

            15.11 ACTION WITHOUT A MEETING. Any action that may be taken at a
meeting of the Limited Partners may be taken without a meeting if an approval
in writing setting forth the action so taken is signed by Limited Partners
holding not less than the minimum percentage of the Outstanding Units that
would be necessary to authorize to take such action at a meeting at which all
the Limited Partners were present and voted. Prompt notice of the taking of
action without a meeting shall be given to the Limited Partners who have not
approved in writing. The General Partner may specify that any written ballot
submitted to Limited Partners for the purpose of taking any action without a
meeting shall be returned to the Partnership within the time period, which
shall be not less than 20 days, specified by the General Partner. If a ballot
returned to the Partnership does not vote all of the Units held by the
Limited Partner, the Partnership shall be deemed to have failed to receive a
ballot for the Units that were not voted. If approval of the taking of any
action by the Limited Partners is solicited by any Person other than by or on
behalf of the General Partner, the written approvals shall have no force and
effect unless and until (a) they are deposited with the Partnership in care
of the General Partner, (b) approvals sufficient to take the action proposed
are dated as of a date not more than 90 days prior to the date sufficient
approvals are deposited with the Partnership and (c) an Opinion of Counsel is
delivered to the General Partner to the effect that the exercise of such
right and the action proposed to be taken with respect to any particular
matter (i) will not cause the Limited Partners to be deemed to be taking part
in the management and control of the business and affairs of the Partnership
so as to jeopardize the Limited Partners' limited liability, (ii) will not
jeopardize the status of the Partnership as a partnership, or cause the
Partnership to be taxable as a corporation or otherwise taxed as an entity,
under applicable tax laws and regulations and (iii) is otherwise permissible
under the state statutes then governing the rights, duties and liabilities of
the Partnership and the Partners.

            (a) Only those Record Holders of Units on the Record Date set
      pursuant to Section 15.6 shall be entitled to notice of, and to vote at, a
      meeting of Limited Partners or to act with respect to matters as to which
      holders of the Outstanding Units have the right to vote or to act. All
      references in this Agreement to votes of, or other acts that may be taken
      by, the holders of Outstanding Units shall be deemed to be references to
      the votes or acts of the Record Holders of such Outstanding Units.

            (b) With respect to Units that are held for a Person's account by
      another Person (such as a broker, dealer, bank, trust company or clearing
      corporation, or an agent of any of the foregoing), in whose name such
      Units are registered, such broker, dealer or other agent shall, in
      exercising the voting rights in respect of such Units on any matter, and
      unless the arrangement between such Persons provides otherwise, vote such
      Units in favor of, and at the direction of, the Person who is the
      beneficial owner, and the Partnership shall be entitled to assume it is so
      acting without further inquiry. The provisions of this Section 15.12(b)
      (as well as all other provisions of this Agreement) are subject to the
      provisions of Section 10.4.

                                   ARTICLE XVI

            16.1  AUTHORITY. Subject to Section 5.10(d) and(e), the

Delaware or any other state of the United States of America, pursuant to a

            16.2  PROCEDURE FOR MERGER OR CONSOLIDATION. Merger or

      limited partnership interests, securities or rights of any constituent
      business entity are not to be exchanged or converted solely for, or into,
      cash, property or

      general or limited partnership interests, rights, securities
      or obligations of any limited partnership, corporation, trust or other

      filing of the certificate of merger pursuant to Section 16.4 or a later
      date specified in or determinable in accordance with the Merger Agreement;
      provided that if the effective time of the merger is to be later than the
      date of the filing of the certificate of merger, it shall be fixed no
      later than the time of the filing of the certificate of merger and stated
      therein; and

            (g) Such other provisions with respect to the proposed merger or
      consolidation as are deemed necessary or appropriate by the General

      affirmative vote or consent of the holders of at least 66 2/3% of the
      Outstanding Units, unless the Merger Agreement contains any provision
      which, if contained in an amendment to this Agreement, the provisions of
      this Agreement or the Delaware Act would require the vote or consent of a
      greater percentage of the Outstanding Units of the Limited Partners or of
      any class of Limited Partners, in which case such greater percentage vote
      or consent shall be required for approval of the Merger Agreement.

            (c) After such approval by vote or consent of the Limited Partners,
      and at any time prior to the filing of the certificate of merger pursuant
      to Section 16.4, the merger or consolidation may be abandoned pursuant to
      provisions therefor, if any, set forth in the Merger Agreement.

      Subsidiary to merge with or into EEM in accordance with the provisions of

            (b) If the Record Holder of Voting Shares determines to exercise its

<Page>

      Certificate of Merger, the Merger Agreement and under the Delaware Act and
      any other applicable Law.

            (c) The Merger Agreement executed in connection with any merger of
      the EEM pursuant to this Section 16.6 shall provide that, at the effective
      time of such merger, each Record Holder of Listed Shares, in exchange for
      the total number of Listed Shares owned by such Record Holder shall
      receive, and the Partnership shall issue or pay to such Record Holder, as
      applicable, a number of whole Class A Common Units and an amount of cash
      in lieu of fractional Class A Common Units such that (i) the product of
      the number of whole Class A Common Units so received by such Record Holder
      and the Closing Price of one Class A Common Unit on the last Trading Day
      prior to the effective time of such merger, plus (ii) the amount of cash
      received by such Record Holder, is equal to the product of the number of
      Listed Shares owned by such Record Holder and the Closing Price of one
      Listed Share on the last Trading Day prior to the effective time of such
      merger. For purposes of this Section 16.6(c), the term "Class A Common
      Units" shall include any other security issued by the Partnership in
      exchange for Listed Shares in lieu of Class A Common Units that is in all
      respects substantially similar to Class A Common Units.

                                  ARTICLE XVII
                             RIGHT TO ACQUIRE UNITS

            17.1   RIGHT TO ACQUIRE UNITS.

            (a) Notwithstanding any provision of this Agreement, if at any time
      less than 15% of the aggregate number of Listed Shares then outstanding
      plus the aggregate number of Common Units then Outstanding are held by
      Persons other than the General Partner and its Affiliates, the General
      Partner shall then have the right (which right it may assign and transfer
      to the Partnership or any Affiliate of the General Partner) exercisable in
      its sole discretion, to purchase all, but not less than all, of the Common
      Units then Outstanding held by Persons other than the General Partner and
      its Affiliates, at the Optional Purchase Price, but only if Enbridge Inc.
      elects to purchase all, but not less than all, of the outstanding Listed
      Shares that are not held by Enbridge Inc. and its Affiliates pursuant to
      Section 4 of the Purchase Provisions. As used in this Agreement, "OPTIONAL
      PURCHASE PRICE" means a price that is equal to the greatest of (A) the
      Current Market Price for the Common Units as of the date five days prior
      to the date that the notice described in Section 17.1(b) is mailed, (B)
      the highest price paid by the General Partner or any of its Affiliates for
      a Common Unit purchased during the 90 calendar day period preceding the
      date that the notice described in Section 17.1(b) is mailed, (C) the
      Current Market Price for the Listed Shares as of the date five days prior
      to the date that the notice described in Section 17.1(b) is mailed, and
      (D) the highest price paid by the General Partner or any of its Affiliates
      for a Listed Share purchased during the 90 calendar day period preceding
      the date that the notice described in Section 17.1(b) is mailed. To the
      extent that the price paid for Listed Shares or Common Units in clauses
      (B) or (D) is paid in securities, the value of such securities shall be
      the Closing Price for such securities on the day the purchase of the
      Listed Shares or Common Units is effected. To the extent that the price
      paid for Listed Shares or Common Units in clauses (B) or (D) is paid other
      than

                                       81
<Page>

      in cash or securities, the value of such other consideration (and
      therefore the price paid for such Listed Shares or Common Units) shall be
      determined in good faith by the Board of Directors of the General Partner.
      As used in this Agreement, (i) "CURRENT MARKET PRICE" of a security listed
      or admitted to trading on any National Securities Exchange means the
      average of the daily Closing Prices for such security for the 20
      consecutive Trading Days immediately prior to, but not including, such
      date; (ii) "CLOSING PRICE" for any day means (1) the last sale price on
      such day, regular way, or in case no such sale takes place on such day,
      the average of the closing bid and asked prices on such day, regular way,
      in either case as reported in the principal consolidated transaction
      reporting system with respect to securities listed or admitted to trading
      on the New York Stock Exchange or, (2) if such securities are not listed
      or admitted to trading on the New York Stock Exchange as reported in the
      principal consolidated transaction reporting system with respect to
      securities listed on the principal National Securities Exchange on which
      such securities are listed or admitted to trading or, if such securities
      are not listed or admitted to trading on any National Securities Exchange,
      the last quoted price on such day or, (3) if not so quoted, the average of
      the high bid and low asked prices on such day in the over-the-counter
      market, as reported by the National Association of Securities Dealers,
      Inc. Automated Quotation System or such other system then in use, or (4)
      if on any such day such securities are not quoted by any such
      organization, the average of the closing bid and asked price on such day
      as furnished by a professional market maker making a market in such
      securities selected by the Board of Directors of the General Partner, or
      (5) if on any such day no market maker is making a market in such
      securities, the fair value of such securities on such day as determined
      reasonably and in good faith by the Board of Directors of the General
      Partner; and (iii) "TRADING DAY" means a day on which the principal
      National Securities Exchange on which such securities are listed or
      admitted to trading is open for the transaction of business or, if such
      securities are not listed or admitted to trading on any National
      Securities Exchange, a day on which banking institutions in New York City
      generally are open. Notwithstanding anything herein to the contrary, the
      Current Market Price of one Class B Common Unit shall be deemed to be the
      same as the Current Market Price of one Class A Common Unit.

            (b) If the General Partner, any Affiliate of the General Partner or
      the Partnership elects to exercise the right to purchase Common Units
      granted pursuant to Section 17.1(a), the General Partner shall deliver to
      the Transfer Agent written notice of such election to purchase (the
      "NOTICE OF ELECTION TO PURCHASE") and shall cause the Transfer Agent to
      mail a copy of such Notice of Election to Purchase to the Record Holders
      of Common Units (as of a Record Date selected by the General Partner) at
      least 10, but not more than 60 days prior to the Purchase Date. Such
      Notice of Election to Purchase shall also be published in daily newspapers
      of general circulation printed in the English language and published in
      the Borough of Manhattan, New York. The Notice of Election to Purchase
      shall specify the Purchase Date and the price (determined in accordance
      with Section 17.1(a)) at which Common Units will be purchased and state
      that the General Partner, its Affiliate or the Partnership, as the case
      may be, elects to purchase such Common Units, upon surrender of
      Certificates representing such Common Units in exchange for payment, at
      such office or offices of the Transfer Agent as the Transfer Agent may
      specify, or as may be required by any National Securities Exchange on
      which the Common Units are listed or admitted to trading. Any such Notice
      of

                                       82
<Page>

      Election to Purchase mailed to a Record Holder of Common Units at his
      address as reflected in the records of the Transfer Agent shall be
      conclusively presumed to have been given whether or not the owner receives
      such notice. On or prior to the Purchase Date, the General Partner, its
      Affiliate or the Partnership, as the case may be, shall deposit with the
      Transfer Agent cash in an amount sufficient to pay the aggregate purchase
      price of all of the Common Units to be purchased in accordance with this
      Section 17.1. If the Notice of Election to Purchase shall have been duly
      given as aforesaid at least 10 days prior to the Purchase Date, and if on
      or prior to the Purchase Date the deposit described in the preceding
      sentence has been made for the benefit of the holders of Common Units
      subject to purchase as provided herein, then from and after the Purchase
      Date, notwithstanding that any Certificate shall not have been surrendered
      for purchase, all rights of the holders of such Common Units (including,
      without limitation, any rights pursuant to Articles IV, V and XIV) shall
      thereupon cease, except the right to receive the purchase price
      (determined in accordance with Section 17.1(a)) for the Common Units
      therefor, without interest, upon surrender to the Transfer Agent of the
      Certificates representing such Common Units, and such Common Units shall
      thereupon be deemed to be transferred to the General Partner, its
      Affiliate or the Partnership, as the case may be, on the record books of
      the Transfer Agent and the Partnership, and the General Partner or any
      Affiliate of the General Partner, or the Partnership, as the case may be,
      shall be deemed to be the owner of all such Common Units from and after
      the Purchase Date and shall have all rights as the owner of such Common
      Units (including, without limitation, all rights as owner pursuant to
      Articles IV, V and XIV).

            (c) At any time from and after the Purchase Date, a holder of an
      Outstanding Common Unit subject to purchase as provided in this Section
      17.1 may surrender his Certificate, as the case may be, evidencing such
      Common Unit to the Transfer Agent in exchange for payment of the amount
      described in Section 17.1(a), therefor without interest thereon.

                                  ARTICLE XVIII
                               GENERAL PROVISIONS

report required or permitted to be given or made to a Partner or Assignee

other means of written communication to the Partner or Assignee at the
address described below. Any notice, payment or report to be given or made to
a Partner or Assignee hereunder shall be deemed conclusively to have been
given or made, and the obligation to give such notice or report or to make
such payment shall be deemed conclusively to have been fully satisfied, upon
sending of such notice, payment or report to the Record Holder of such Unit
at his address as shown on the records of the Transfer Agent or as otherwise
shown on the records of the Partnership, regardless of any claim of any
Person who may have an interest in such Unit or the Partnership Interest of a
General Partner by reason of any assignment or otherwise. An affidavit or
certificate of making of any notice, payment or report in accordance with the
provisions of this Section 18.1 executed by the General Partner, the Transfer
Agent or the mailing organization shall be prima facie evidence of the giving
or making of such notice, payment or report. If any notice, payment or report
addressed to a Record Holder at the address

of such Record Holder appearing on the books and records of the Transfer
Agent or the Partnership is returned by the United States Post Office marked
to indicate that the United States Postal Service is unable to deliver it,
such notice, payment or report and any subsequent notices, payments and
reports shall be deemed to have been duly given or made without further
mailing (until such time as such Record Holder or another Person notifies the
Transfer Agent or the Partnership of a change in his address) if they are
available for the Partner or Assignee at the principal office of the
Partnership for a period of one year from the date of the giving or making of
such notice, payment or report to the other Partners and Assignees. Any
notice to the Partnership shall be deemed given if received by the General
Partner at the principal office of the Partnership designated pursuant to
Section 1.3. The General Partner may rely and shall be protected in relying
on any notice or other document from a Partner, Assignee or other Person if
believed by it to be genuine.

performance of any covenant, duty, agreement or condition of this Agreement
or to exercise any right or remedy consequent upon a breach thereof shall

            18.9  COUNTERPARTS. This Agreement may be executed in
counterparts, all of which together shall constitute an agreement binding on
all the parties hereto, notwithstanding that all such parties are not
signatories to the original or the same counterpart. Each party shall become
