        SECTION 4.4    Amounts Withheld.    All amounts withheld pursuant to the
Code or any provision of any other tax law with respect to any income or gain
realized by the Company or any payment or distribution to the Company or the
Members shall be treated as amounts distributed to the Members pursuant to this
Section 4.4 for all purposes under this Agreement. The Managing Member is
authorized to withhold from distributions, or with respect to allocations, to
any Member and to pay over to any government any amounts required to be so
withheld pursuant to the Code or any provisions of any other tax law, and shall
allocate any such amounts to the Members with respect to which such amounts were

gain, loss and deduction inherent in such property (that has not been reflected
in the Capital Account previously) would be allocated among the Members if there
were a taxable disposition of such property for the fair market value of such
property (taking into account section 7701(g) of the Code) on the date of
distribution.

        (d)  The Managing Member shall direct the Company's accountant to make
all necessary adjustments in each Member's Capital Account as required by the
capital accounting rules of section 704(b) of the Code and the regulations
thereunder.

        SECTION 5.3    Allocations of Profits and Losses.    A Member's
distributive share of the Company's total income, gain, loss, deduction or
credit (or items thereof), which total shall be as shown on the annual federal
income tax return prepared by the Company's accountants or as finally determined
by the Internal Revenue Service or the courts, and as modified by the capital
accounting rules of section 704(b) of the Code and the regulations thereunder as
implemented by Section 5.2 hereof, as applicable, shall be determined as
follows:

        (a)  General. Except as otherwise provided for in this Section 5.3, all
items of income, gain, loss, deduction and credit shall be allocated solely to
the Managing Member.

        (b)  Loss Limitation. Notwithstanding anything in this Section 5.3 to
the contrary, items of loss and deduction allocated to any Member pursuant to
this Section 5.3 with respect to any taxable period shall not exceed the maximum
amount of such items that can be so allocated to such Member without causing
such Member to have a deficit balance in its Capital Account in excess of the
amount of such Member's obligation, if any, to restore such deficit Capital
Account, computed and adjusted in accordance with the rules of
section 1.704-1(b)(2)(ii)(d) of the Income Tax Regulations (including such
Member's share of minimum gain and partner nonrecourse debt minimum gain as
provided in sections 1.704-2(g) and 2(i)(5) of the Income Tax Regulations). Any
such items of loss or deduction in excess of the limitation set forth in the
preceding sentence shall be allocated to those Members who would not be subject
to such limitation, proportionately in accordance with their relative positive
Adjusted Capital Account balances.

        (c)  Section 704(c) Allocations. Solely for tax purposes, in determining
each Member's allocable share of the taxable income or loss of the Company,
depreciation, depletion, amortization and gain or loss with respect to any
contributed property, or with respect to revalued property where Company
property is revalued pursuant to section 1.704-1(b)(2)(iv)(f) of the Income Tax
Regulations, shall be allocated to the Members under the traditional method as
provided in section 1.704-3(b) of the Income Tax Regulations.

        (d)  Minimum Gain Chargeback. Notwithstanding anything to the contrary
in this Section 5.3, if there is a net decrease in Partnership Minimum Gain or
Partner Nonrecourse Debt Minimum Gain (as such terms are defined in sections
1.704-2(b) and 1.704-2(i)(2), respectively, of the Income Tax Regulations)
during a Company taxable year, then each Member shall be allocated

10

--------------------------------------------------------------------------------

items of Company income and gain for such year (and, if necessary, for
subsequent years), to the extent required by, and in the manner provided in,
section 1.704-2 of the Income Tax Regulations.

        (e)  Qualified Income Offset. Subject to the provisions of
Section 5.3(d), but otherwise notwithstanding anything to the contrary in this
Section 5.3, if any Member's Capital Account has a deficit balance in excess of
such Member's obligation to restore its Capital Account balance, computed in
accordance with the rules of section 1.704-l(b)(2)(ii)(d) of the Income Tax
Regulations (including such Member's share of minimum gain and partner
nonrecourse debt minimum gain as provided in sections 1.704-2(g) and
1.704-2(i)(5) of the Income Tax Regulations), then sufficient amounts of income
and gain (consisting of a pro rata portion of each item of Company income,
including gross income, and gain for such year) shall be allocated to such
Member in an amount and manner sufficient to eliminate such deficit as quickly
as possible.

        (f)    Depreciation Recapture. Solely for tax purposes, gain recognized
(or deemed recognized under the provisions hereof) upon the sale or other
disposition of Company property, which is treated as depreciation recapture,
shall be allocated among the Members as provided in sections 1.704-3(a)(11),
1.1245-1(e) and 1.1250-1(f) of the Income Tax Regulations.

        (g)  Closing of the Books. Except as otherwise required by law, if the
Interests of the Members herein change during any taxable period, all items to
be allocated to the Members for such entire taxable year shall be allocated
based upon a closing of the books methodology as of the date upon which such
change occurred.

        (h)  Curative Allocation. Any allocation pursuant to Sections 5.3(b) or
5.3(e) hereof shall be taken into account in computing subsequent allocations
pursuant to this Section 5.3 so that the net amount of all such allocations to
each Member shall, to the extent possible, be equal to the net amount that would
have been allocated to each such Member pursuant to the provisions of this
Section 5.3 if the allocations made pursuant to Sections 5.3(b) and 5.3(e)
hereof had not occurred. It is anticipated that allocations of items of loss and
deduction pursuant to Section 5.3(k) hereof will be offset by allocations
pursuant to Section 5.3(d) hereof. To the extent the Managing Member determines
that any such amounts allocated pursuant to Section 5.3(k) hereof are unlikely
to be offset by a countervailing allocation of pursuant to Section 5.3(d)
hereof, then so much of such allocation as the Manager has determined is
unlikely to be offset shall also be taken into account in computing subsequent
allocations pursuant to this Section 5.3 so that the net amount of all such
allocations shall, to the extent possible, equal the net amount that would be
allocated to such Members in the absence of such special allocations.

        (i)    Adjustment to Reflect Targeted Capital Account. Subject to the
provisions of Sections 5.3(b) through (h), and subject to Section 5.3(k), items
of income, gain, deduction and loss shall be allocated among the Members in such
a manner as to cause each Member's Adjusted Capital Account balance to equal, as
nearly as practicable, such Member's Targeted Capital Account balance.

        (j)    Nonrecourse Deductions. Items of deduction and loss attributable
to "partner nonrecourse debt" within the meaning of section 1.704-2(b)(4) of the
Income Tax Regulations shall be allocated to the Members bearing the economic
risk of loss with respect to such debt in accordance with section 1.704-2(i)(1)
of the Income Tax Regulations. Items of deduction and loss attributable to
"nonrecourse debt" of the Company within the meaning of section 1.752-2 of the
Income Tax Regulations shall be allocated to the Members in proportion to the
items of loss and deduction allocable pursuant to Section 5.3(i) hereof.

        (k)  Consent by Members. The methods hereinabove set forth by which
income, gains, losses, deductions, credits and distributions are allocated and
apportioned are hereby expressly consented to by each Member as a specific
condition to becoming a Member. Each Member covenants that

11

--------------------------------------------------------------------------------

he or it will make no claim or representation concerning the income tax effects
of the provisions contained in this Agreement that is inconsistent with the
provisions of this Agreement.

        SECTION 5.4    Expenses.    Except as otherwise agreed to by the
Members, the Managing Member shall bear and be responsible for all expenses
incurred in connection with the formation and operation of the Company.

filed and shall file or cause such returns to be timely filed. The Managing
Member shall determine the appropriate treatment of each item of income, gain,
loss, deduction and credit of the Company and the accounting methods and
conventions under the tax laws of the United States, the several states and
other relevant jurisdictions as to the treatment of any such item or any other
method or procedure related to the preparation of such tax returns. The Managing
Member may cause the Company to make or refrain from making any and all
elections permitted by such tax laws. The Company and each Member hereby
designate the Managing Member as the "tax matters partner" for purposes of

such withdrawal shall be permitted in connection with the termination of a
Member's employment with NorthWestern, NGC or any of their affiliates).

of the Income Tax Regulations), or if later within ninety (90) days after the
date of such dissolution, the assets of the Company shall be distributed in the

Transfer will not (and if requested by the Managing Member, the Member proposing
to Transfer such Interest obtains for the Company an opinion of counsel, in

14

--------------------------------------------------------------------------------

form and substance satisfactory to the Managing Member in its reasonable

requirements shall be admitted as a Member with respect to the Interest so

Member, the Managing Member shall forthwith cause any necessary papers to be
