Ladies and Gentlemen:

         Northwestern Capital Financing III (the "Trust"), a statutory business
trust organized under the Business Trust Act (the "Delaware Act") of the State
of Delaware (Chapter 38, Title 12 of the Delaware Code, 12 Del. C. ss. 3801 et
seq.) confirms its agreement with Morgan Stanley & Co. Incorporated, Merrill
Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith Incorporated, Salomon Smith
Barney Inc. and each of the Underwriters named in Schedule A hereto
(collectively the "Underwriters," which term shall also include any underwriter
substituted as hereinafter provided in Section 10 hereof), for whom Morgan
Stanley & Co. Incorporated, Merrill Lynch, Pierce, Fenner & Smith Incorporated
and Salomon Smith Barney Inc. are acting as Representatives (in such capacity,
the "Representatives") with respect to the issue and sale by the Trust and the
purchase by the Underwriters, acting severally and not jointly, of 8.10% Trust
Preferred Securities (liquidation amount $25 per preferred security) in the
respective numbers set forth in said Schedule A hereto (the "Initial Preferred
Securities"), and with respect to the grant by the Trust to the Underwriters,
acting severally and not jointly, of the option described in Section 2(b) hereof
to purchase all or any part of the additional Preferred Securities described
below to cover over-allotments, if any. The aforesaid 4,000,000 Initial





Preferred Securities and all or part of the 600,000 Preferred Securities subject
to the option described in Section 2(b) hereof (the "Option Preferred
Securities") are hereinafter called, collectively, the "Preferred Securities."
The Preferred Securities are more fully described in the Prospectus (as defined
below).

         The Preferred Securities will be guaranteed by NorthWestern Corporation
(a Delaware corporation) (the "Company"), to the extent set forth in the
Prospectus, with respect to distributions and amounts payable upon liquidation
or redemption (the "Preferred Securities Guarantee") pursuant to the Preferred
Securities Guarantee Agreement (the "Preferred Securities Guarantee Agreement")
to be dated as of the Closing Time (as defined herein), executed and delivered
by the Company and Wilmington Trust Company (the "Guarantee Trustee"). The
Company and the Trust each understand that the Underwriters propose to make a
public offering of the Preferred Securities as soon as the Representatives deem
advisable after this Agreement has been executed and delivered, and the
Declaration (as defined herein), the Indenture (as defined herein), and the
Preferred Securities Guarantee Agreement have been qualified under the Trust
Indenture Act of 1939, as amended (the "1939 Act"). The entire proceeds from the
sale of the Preferred Securities will be combined with the entire proceeds from
the sale by the Trust to the Company of its common securities (the "Common
Securities") guaranteed by the Company, to the extent set forth in the
Prospectus, with respect to distributions and amounts payable upon liquidation
or redemption pursuant to the Common Securities Guarantee Agreement (the "Common
Securities Guarantee Agreement" and, together with the Preferred Securities
Guarantee Agreement, the "Guarantee Agreements"), to be dated as of the Closing
Time, executed and delivered by the Company for the benefit of the holders from
time to time of the Common Securities, and will be used by the Trust to purchase
$103,092,800 aggregate principal amount of 8.10% Junior Subordinated Deferrable
Interest Debentures due January 15, 2032 (the "Debentures") issued by the
Company and, if all or part of the Option Preferred Securities are purchased, up
to approximately an additional $15,463,925 aggregate principal amount of
Debentures (the "Option Debentures"). The aforesaid Initial Debentures and
Option Debentures are hereinafter called, collectively, the "Debentures." The
Preferred Securities and the Common Securities will be issued pursuant to the
Amended and Restated Declaration of Trust of the Trust, to be dated as of the
Closing Time (the "Declaration"), among the Company, as Sponsor, Wilmington
Trust Company, as property trustee (the "Property Trustee"), and Merle D. Lewis
and Richard R. Hylland, as administrative trustees (the "Administrative
Trustees" and together with the Property Trustee, the "Trustees"), and the
holders from time to time of undivided beneficial interests in the assets of the
Trust. The Debentures will be issued pursuant to an Indenture, dated as of
August 1, 1995 (the "Base Indenture"), between the Company and JPMorgan Chase
Bank (as successor to The Chase Manhattan Bank, N.A.), as trustee (the
"Debenture Trustee"), and a supplement to the Base Indenture, to be dated as of
the Closing Time (the "Supplemental Indenture," and together with the Base
Indenture as heretofore supplemented and amended, the "Indenture"), between the
Company and the Debenture Trustee. The Preferred Securities, the Preferred
Securities Guarantee and the Debentures are collectively referred to herein as
the "Securities." Capitalized terms used herein without definition have the
respective meanings specified in the Prospectus.

         The Company and the Trust have filed with the Securities and Exchange
Commission (the "Commission") registration statements on Form S-3 (Nos.
333-58491 and 333-82707), including a prospectus, relating to securities of the
Company and the Trust. Such registration



                                       2


statements were filed under the Securities Act of 1933, as amended (the "1933
Act"), and have become effective. Promptly after execution and delivery of this
Agreement, the Company will prepare and file with the Commission a prospectus in
accordance with the provisions of paragraph (b) of Rule 424 ("Rule 424(b)") of
the rules and regulations of the Commission under the 1933 Act (the "1933 Act
Regulations"). The prospectus included in the registration statement No.
333-82707 at the time it became effective, as supplemented to reflect the terms
of the Securities and the terms of the offering of the Securities, as first
filed with the Commission pursuant to and in accordance with Rule 424(b) under
the 1933 Act Regulations, including all material incorporated by reference
therein pursuant to Item 12 of Form S-3 under the 1933 Act, is hereinafter
referred to as the "Prospectus." No document has been or will be prepared or
distributed in reliance on Rule 434 under the Act. "Preliminary prospectus"
shall be deemed to refer to (i) any prospectus used before the Registration
Statement (as defined herein) became effective and (ii) any prospectus that
omitted, as applicable, information pursuant to Rule 430A(b) of the 1933 Act
Regulations or other information to be included upon pricing in a prospectus
filed with the Commission pursuant to Rule 424(b) and was used after such
effectiveness and prior to the initial delivery of the Prospectus to the
underwriters by the Company. Such registration statements, including the
exhibits thereto (other than Form T-1), schedules thereto, if any, and the
documents incorporated by reference therein pursuant to Item 12 of Form S-3
under the 1933 Act, at the time registration statement No. 333-82707 became
effective and including the prospectus included in such registration statement
at the time it became effective, as supplemented to reflect the terms of the
Securities and the terms of the offering of the Securities, as first filed with
the Commission pursuant to and in accordance with Rule 424(b) under the 1933 Act
Regulations, are collectively herein called the "Registration Statement",
provided that references to the Registration Statement at the time it became
effective shall not be deemed to include the information first filed pursuant to
and in accordance with Rule 424(b) under the 1933 Act Regulations. For purposes
of this Agreement, all references to the Registration Statement, any preliminary
prospectus, the Prospectus or any amendment or supplement to any of the
foregoing shall be deemed to include the copy filed with the Commission pursuant
to its Electronic Data Gathering, Analysis and Retrieval system ("EDGAR").

         All references in this Agreement to financial statements and schedules
and other information which is "contained," "included" or "stated" in the
Registration Statement, any preliminary prospectus or the Prospectus (or other
references of like import) shall be deemed to mean and include all such
financial statements and schedules and other information which is incorporated
by reference in the Registration Statement, any preliminary prospectus or the
Prospectus, as the case may be; and all references in this Agreement to
amendments or supplements to the Registration Statement, any preliminary
prospectus or the Prospectus shall be deemed to mean and include the filing of
any document under the Securities Exchange Act of 1934 (the "1934 Act") which is
incorporated by reference in the Registration Statement, any preliminary
prospectus or the Prospectus, as the case may be.

         SECTION 1. REPRESENTATIONS AND WARRANTIES.

         (a) REPRESENTATIONS AND WARRANTIES BY THE COMPANY AND THE TRUST. The
Company and the Trust jointly and severally represent and warrant to each
Underwriter as of the date



                                       3


hereof, as of the Closing Time referred to in Section 2(c) hereof, and as of
each Date of Delivery (if any) referred to in Section 2(b) hereof, and agrees
with each Underwriter, as follows:

             (i) COMPLIANCE WITH REGISTRATION REQUIREMENTS. The Company meets
the requirements for use of Form S-3 under the 1933 Act. The Registration
Statement has become effective under the 1933 Act and no stop order suspending
the effectiveness of the Registration Statement has been issued under the 1933
Act and no proceedings for that purpose have been instituted or are pending or,
to the knowledge of the Company and the Trust, are contemplated by the
Commission, and any request on the part of the Commission for additional
information has been complied with.

         At the respective times the Registration Statement and any
post-effective amendments thereto became effective, at the time of the filing by
the Company of any annual report on Form 10-K, and at the Closing Time (and, if
any Option Securities are purchased, at the Date of Delivery), the Registration
Statement and any amendments and supplements thereto complied and will comply in
all material respects with the requirements of the 1933 Act and the 1933 Act
Regulations and the 1939 Act and the rules and regulations of the Commission
under the 1939 Act (the "1939 Act Regulations") and did not and will not contain
an untrue statement of a material fact or omit to state a material fact required
to be stated therein or necessary to make the statements therein not misleading.
Neither the Prospectus nor any amendments or supplements thereto, at the time
the Prospectus or any such amendment or supplement was issued and at the Closing
Time (and, if any Option Securities are purchased, at the Date of Delivery),
included or will include an untrue statement of a material fact or omitted or
will omit to state a material fact necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading. The representations and warranties in this subsection shall not
apply (A) to statements in or omissions from the Registration Statement or
Prospectus made in reliance upon and in conformity with information furnished to
the Trust or the Company in writing by any Underwriter through Morgan Stanley &
Co. Incorporated expressly for use in the Registration Statement or Prospectus
or (B) to that part of the Registration Statement that constitutes the
Statements of Eligibility and Qualification on Form T-1 (the "Form T-1") under
the Trust Indenture Act of the Debenture Trustee, the Property Trustee and the
Guarantee Trustee.

         Each preliminary prospectus and the prospectus filed as part of the
Registration Statement as originally filed or as part of any amendment thereto,
or filed pursuant to Rule 424 under the 1933 Act, complied when so filed in all
material respects with the 1933 Act Regulations and each preliminary prospectus
and the Prospectus delivered to the Underwriters for use in connection with this
offering was identical to the electronically transmitted copies thereof filed
with the Commission pursuant to EDGAR, except to the extent permitted by
Regulation S-T.

             (ii) INCORPORATED DOCUMENTS. The documents incorporated or deemed
to be incorporated by reference in the Registration Statement and the
Prospectus, when they were or hereafter are filed with the Commission, complied
and will comply in all material respects with the requirements of the 1933 Act
and the 1933 Act Regulations or the 1934 Act and the rules and regulations of
the Commission thereunder (the "1934 Act Regulations"), as applicable, and, when
read together with the other information in the Prospectus, at the time the
Registration


                                       4


Statement became effective, at the time the Prospectus was issued and at the
Closing Time (and, if any Option Securities are purchased, at the Date of
Delivery), did not and will not contain an untrue statement of a material fact
or omit to state a material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading.

             (iii) INDEPENDENT ACCOUNTANTS. The accountants who certified the
financial statements and supporting schedules included in the Registration
Statement and Prospectus are independent public accountants as required by the
1933 Act and the 1933 Act Regulations.

             (iv) FINANCIAL STATEMENTS. The financial statements included in the
Registration Statement and the Prospectus, together with the related schedules
and notes, present fairly the financial position of the Company and its
consolidated subsidiaries at the dates indicated and the statement of
operations, stockholders' equity and cash flows of the Company and its
consolidated subsidiaries for the periods specified; said financial statements
have been prepared in conformity with generally accepted accounting principles
("GAAP") applied on a consistent basis (except that the unaudited financial
statements may be subject to normal year-end adjustments) throughout the periods
involved. The supporting schedules, if any, included in the Registration
Statement present fairly in accordance with GAAP the information required to be
stated therein. The selected financial data and any summary financial
information included in the Prospectus present fairly the information shown
therein and have been compiled on a basis consistent with that of the audited
and unaudited financial statements included in the Registration Statement. In
addition, any pro forma financial statements and the related notes thereto
included in the Registration Statement and the Prospectus, have been prepared in
accordance with the Commission's rules and guidelines with respect to pro forma
financial statements and have been properly compiled on the bases described
therein, and the assumptions used in the preparation thereof are reasonable and
the adjustments used therein are appropriate to give effect to the transactions
and circumstances referred to therein.

             (v) NO MATERIAL ADVERSE CHANGE IN BUSINESS. Since the respective
dates as of which information is given in the Registration Statement and the
Prospectus, except as otherwise stated therein, (A) there has been no material
adverse change in the condition, financial or otherwise, or in the earnings,
business affairs or business prospects of the Company and its subsidiaries
considered as one enterprise, whether or not arising in the ordinary course of
business (a "Material Adverse Effect"), (B) there have been no transactions
entered into by the Company or any of its subsidiaries, other than those in the
ordinary course of business, which are material with respect to the Company and
its subsidiaries considered as one enterprise, and (C) except for dividends on
the 4-1/2% Series and the 6-1/2% Series of preferred stock and regular quarterly
dividends on the Common Stock in amounts per share that are consistent with past
practice, there has been no dividend or distribution of any kind declared, paid
or made by the Company on any class of its capital stock.

             (vi) GOOD STANDING OF THE COMPANY. The Company has been duly
incorporated and is validly existing as a corporation in good standing under the
laws of the State of Delaware and has corporate power and authority and
franchises to own or lease and operate its properties and to conduct its
business as described in the Prospectus and to enter into and perform its
obligations under this Agreement; and the Company is authorized as a
domesticated



                                       5


foreign corporation to transact business, and is in good standing, in the State

and compliance by the Company and the Trust with their obligations hereunder
have been duly authorized by all necessary corporate action and do not and will

assets thereof or the consummation of the transactions contemplated in this
Agreement or the performance by the Company or the Trust of its obligations
hereunder; the aggregate of all pending legal or governmental proceedings to
which the Company or any subsidiary is a party or of which any of their
respective property or assets is the subject which are not described in the

business, could not reasonably be expected to result in a Material Adverse
Effect.

             (xx) ACCURACY OF EXHIBITS. There are no contracts or documents
which are required to be described in the Registration Statement, the Prospectus
or the documents incorporated by reference therein or to be filed as exhibits

its subsidiaries therein, and which infringement, conflict, invalidity or
inadequacy, singly or in the aggregate, might reasonably be expected to result

Adverse Effect; the Company and its subsidiaries are in compliance with the
terms and conditions of all such Governmental Licenses, except where the failure
so to comply would not, singly or in the aggregate, have a Material Adverse
Effect; all of the Governmental Licenses are valid and in full force and effect,

Governmental Licenses to be in full force and effect would not have a Material
Adverse Effect; and neither the Company nor any of its subsidiaries has received

Governmental Licenses which, singly or in the aggregate, would result in a
Material Adverse Effect.

             (xxiv) TITLE TO PROPERTY. The Company and its subsidiaries have

         SECTION 2. SALE AND DELIVERY TO UNDERWRITERS; CLOSING.

         (a) INITIAL PREFERRED SECURITIES. On the basis of the representations
and warranties herein contained and subject to the terms and conditions herein
set forth, the Trust agrees to sell to each Underwriter, severally and not
jointly, and each Underwriter, severally and not jointly, agrees to purchase
from the Company, at the purchase price of $25 per Preferred Security, the
number of Initial Preferred Securities set forth in Schedule A opposite the name
of such Underwriter, plus any additional number of Initial Preferred Securities
which such Underwriter may become obligated to purchase pursuant to the
provisions of Section 10 hereof.

         (b) OPTION PREFERRED SECURITIES. In addition, on the basis of the
representations and warranties herein contained and subject to the terms and
conditions herein set forth, the Trust hereby grants an option to the
Underwriters, severally and not jointly, to purchase up to an additional 600,000
Preferred Securities (the "Option Preferred Securities") at a price per Option
Preferred Security equal to the price per Initial Preferred Security plus
accumulated distributions,


                                       11


if any, from January 31, 2002 to the date of delivery and payment. Such option
will expire 30 days after the date of this Agreement and may be exercised in
whole or in part from time to time only for the purpose of covering
over-allotments which may be made in connection with the offering and
distribution of the Initial Preferred Securities upon notice by the
Representatives to the Trust and the Company setting forth the number of Option
Preferred Securities as to which the several Underwriters are then exercising
the option and the time, date and place of payment and delivery for such Option
Preferred Securities. Any such time and date of payment and delivery (each, a
"Date of Delivery") shall be determined by the Representatives, the Trust and
the Company, but shall not be sooner than four business days or later than seven
full business days after the exercise of said option, nor in any event prior to
the Closing Time, as hereinafter defined, unless agreed by the Representatives,
the Trust and the Company. If the option is exercised as to all or any portion
of the Option Preferred Securities, each of the Underwriters, acting severally
and not jointly, will purchase that proportion of the total number of Option
Preferred Securities then being purchased which the number of Initial Preferred
Securities set forth in Schedule A opposite the name of such Underwriter bears
to the total number of Initial Preferred Securities, subject in each case to
such adjustments as the Representatives in their discretion shall make to
eliminate any sales or purchases of fractional shares.

         (c) PAYMENT. As compensation to the Underwriters for their commitments
hereunder and in view of the fact that the proceeds of the sale of the Preferred
Securities will be used to purchase the Debentures, the Company hereby agrees to
pay at the Closing Time and at each Date of Delivery to the Underwriters a
commission of $0.7875 per Preferred Security. Payment of the purchase price for,
and delivery of certificates for, the Preferred Securities shall be made at the
offices of Paul, Hastings, Janofsky & Walker LLP, 399 Park Avenue, New York, New
York 10022, or at such other place as shall be agreed upon by the
Representatives, the Company and the Trust, at 9:00 A.M. (Eastern time) on the
third (fourth, if the pricing occurs after 4:30 p.m. (Eastern time) on any given
day) business day after the date hereof (unless postponed in accordance with the
provisions of Section 10), or such other time not later than ten business days
after such date as shall be agreed upon by the Representatives, the Company and
the Trust (such time and date of payment and delivery being herein called
"Closing Time").

         In addition, in the event that any or all of the Option Preferred
Securities are purchased by the Underwriters, payment of the purchase price for,
and delivery of such Option Preferred Securities, shall be made at the
above-mentioned offices, or at such other place as shall be agreed upon by the
Representatives, the Trust and the Company, on the relevant Date of Delivery as
specified in the notice from the Representatives to the Trust and the Company.

         Payment shall be made to the Trust by wire transfer of immediately
available funds to the order of the Trust, against delivery to Morgan Stanley &
Co. Incorporated for the respective accounts of the Underwriters of certificates
for the Preferred Securities to be purchased by them. It is understood that each
Underwriter has authorized Morgan Stanley & Co. Incorporated, for its account,
to accept delivery of, receipt for, and make payment of the purchase price for
the Initial Preferred Securities and the Option Preferred Securities, if any,
which it has agreed to purchase. Morgan Stanley & Co. Incorporated, individually
and not as representative of the Underwriters, may (but shall not be obligated
to) make payment of the purchase price for the Initial Preferred Securities or
the Option Preferred Securities, if any, to be purchased by any Underwriter
whose


                                       12


funds have not been received by the Closing Time or the relevant Date of
Delivery, as the case may be, but such payment shall not relieve such
Underwriter from its obligations hereunder.

         At Closing Time, or the Date of Delivery, as the case may be, the
Company will pay, or cause to be paid, the commission payable at such time under
this Section 2 to Morgan Stanley & Co. Incorporated on behalf of the
Underwriters by wire transfer of immediately available funds.

         (d) DENOMINATIONS; REGISTRATION. Certificates for the Initial Preferred
Securities and the Option Preferred Securities, if any, shall be in such
denominations and registered in such names as the Representatives may request in
writing at least two full business days before the Closing Time or the relevant
Date of Delivery, as the case may be. The certificates for the Initial Preferred
Securities and the Option Preferred Securities, if any, will be made available
for examination and packaging by the Representatives in The City of New York not
later than 5:00 P.M. (Eastern time) on the business day prior to the Closing
Time or the relevant Date of Delivery, as the case may be.

         SECTION 3. COVENANTS OF THE COMPANY AND THE TRUST. The Company and the
Trust jointly and severally covenant with each Underwriter as follows:

         (a) COMPLIANCE WITH SECURITIES REGULATIONS AND COMMISSION REQUESTS. The
Company and the Trust, subject to Section 3(b), will notify the Representatives
immediately, and confirm the notice in writing, (i) when any post-effective
amendment to the Registration Statement shall become effective, or any
supplement to the Prospectus or any amended Prospectus shall have been filed,
(ii) of the receipt of any comments from the Commission, (iii) of any request by
the Commission for any amendment to the Registration Statement or any amendment
or supplement to the Prospectus or for additional information and (iv) of the
issuance by the Commission of any stop order suspending the effectiveness of the
Registration Statement or of any order preventing or suspending the use of any
preliminary prospectus, the Prospectus, or of the suspension of the
qualification of the Preferred Securities for offering or sale in any
jurisdiction or of the initiation or threatening of any proceedings for any of
such purposes. The Company and the Trust will promptly effect the filings
necessary pursuant to Rule 424(b) and will take such steps as they deem
necessary to ascertain promptly whether the form of prospectus transmitted for
filing under Rule 424(b) was received for filing by the Commission and, in the
event that it was not, it will promptly file such prospectus. The Company and
the Trust will make every reasonable effort to prevent the issuance of any stop
order and, if any stop order is issued, to obtain the lifting thereof at the
earliest possible moment.

         (b) FILING OF AMENDMENTS. The Company and the Trust will give the
Representatives notice of their intention to file or prepare any amendment to
the Registration Statement or any amendment, supplement or revision to either
the prospectus included in the Registration Statement at the time it became
effective or to the Prospectus, whether pursuant to the 1933 Act, the 1934 Act
or otherwise, will furnish the Representatives with copies of any such documents
a reasonable amount of time prior to such proposed filing or use, as the case
may be, and will not file or use any such document to which the Representatives
or counsel for the Representatives shall reasonably object.


                                       13


         (c) DELIVERY OF REGISTRATION STATEMENTS. The Company and the Trust have
furnished or will deliver to the Representatives and counsel for the
Underwriters, at their request and without charge, conformed copies of the
Registration Statement as originally filed and of each amendment thereto
(including exhibits filed therewith or incorporated by reference therein and
documents incorporated or deemed to be incorporated by reference therein), and
conformed copies of all consents and certificates of experts. The copies of the
Registration Statement and each amendment thereto furnished to the Underwriters
will be identical to the electronically transmitted copies thereof filed with
the Commission pursuant to EDGAR, except to the extent permitted by Regulation
S-T.

         (d) DELIVERY OF PROSPECTUS. The Company and the Trust have delivered to
each Underwriter, without charge, as many copies of each preliminary prospectus
as such Underwriter reasonably requested, and the Company hereby consents to the
use of such copies for purposes permitted by the 1933 Act. The Company will
furnish to each Underwriter, without charge, during the period when the
Prospectus is required to be delivered under the 1933 Act or the 1934 Act, such
number of copies of the Prospectus (as amended or supplemented) as such
Underwriter may reasonably request. The Prospectus and any amendments or
supplements thereto furnished to the Underwriters will be identical to the
electronically transmitted copies thereof filed with the Commission pursuant to
EDGAR, except to the extent permitted by Regulation S-T.

         (e) CONTINUED COMPLIANCE WITH SECURITIES LAWS. The Company and the
Trust will comply with the 1933 Act and the 1933 Act Regulations and the 1934
Act and the 1934 Act Regulations so as to permit the completion of the
distribution of the Securities as contemplated in this Agreement and in the
Prospectus. If at any time when a prospectus is required by the 1933 Act to be
delivered in connection with sales of the Preferred Securities, any event shall
occur or condition shall exist as a result of which it is necessary, in the
reasonable opinion of counsel for the Underwriters or for the Company, to amend
the Registration Statement or amend or supplement the Prospectus in order that
the Prospectus will not include any untrue statements of a material fact or omit
to state a material fact necessary in order to make the statements therein not
misleading in the light of the circumstances existing at the time it is
delivered to a purchaser, or if it shall be necessary, in the reasonable opinion
of such counsel, at any such time to amend the Registration Statement or amend
or supplement the Prospectus in order to comply with the requirements of the
1933 Act or the 1933 Act Regulations, the Company and the Trust will promptly
prepare and file with the Commission, subject to Section 3(b), such amendment or
supplement as may be necessary to correct such statement or omission or to make
the Registration Statement or the Prospectus comply with such requirements, and
the Company will furnish to the Underwriters such number of copies of such
amendment or supplement as the Underwriters may reasonably request.

         (f) BLUE SKY QUALIFICATIONS. The Company and the Trust will each use
its reasonable best efforts, in cooperation with the Underwriters, to qualify
the Preferred Securities for offering and sale under the applicable securities
laws of such states and other jurisdictions (domestic or foreign) as the
Representatives may designate and to maintain such qualifications in effect for
a period of not less than one year from the effective date of the Registration
Statement; PROVIDED, HOWEVER, that neither the Company nor the Trust shall be
obligated to file any general consent to service of process or to qualify as a

         SECTION 6. INDEMNIFICATION.

         (a) INDEMNIFICATION OF UNDERWRITERS. Each of the Company and the Trust
jointly and severally agrees to indemnify and hold harmless each Underwriter and
each person, if any, who controls any Underwriter within the meaning of Section
15 of the 1933 Act or Section 20 of the 1934 Act as follows:

                    (i) against any and all loss, liability, claim, damage and
          expense whatsoever, as incurred, arising out of any untrue statement
          or alleged untrue statement of a material fact contained in the
          Registration Statement (or any amendment thereto) or the omission or
          alleged omission therefrom of a material fact required to be stated
          therein or necessary to make the statements therein not misleading or
          arising out of any untrue statement or alleged untrue statement of a
          material fact included in any preliminary prospectus or the Prospectus
          (or any amendment or supplement thereto), or the omission or alleged
          omission therefrom of a material fact necessary in order to make the
          statements therein, in the light of the circumstances under which they
          were made, not misleading;

                    (ii) against any and all loss, liability, claim, damage and
          expense whatsoever, as incurred, to the extent of the aggregate amount
          paid in settlement of any litigation, or any investigation or
          proceeding by any governmental agency or body, commenced or
          threatened, or of any claim whatsoever based upon any such untrue
          statement or omission, or any such alleged untrue statement or
          omission provided that (subject to Section 6(e) below) any such
          settlement is effected with the written consent of the Company; and

                    (iii) against any and all expense whatsoever, as incurred
          (including the fees and disbursements of counsel chosen by Morgan
          Stanley & Co. Incorporated), reasonably incurred in investigating,
          preparing or defending against any litigation, or any


                                       20


          investigation or proceeding by any governmental agency or body,
          commenced or threatened, or any claim whatsoever based upon any such
          untrue statement or omission, or any such alleged untrue statement or
          omission, to the extent that any such expense is not paid under (i) or
          (ii) above;

PROVIDED, HOWEVER, that this indemnity agreement shall not apply to any loss,
liability, claim, damage or expense to the extent arising out of any untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished to the Company by any
Underwriter through Morgan Stanley & Co. Incorporated expressly for use in the
Registration Statement (or any amendment thereto) or any preliminary prospectus
or the Prospectus (or any amendment or supplement thereto); and PROVIDED,
FURTHER, that this indemnity shall not apply to any preliminary prospectus or
any amendment or supplement thereto to the extent that any such loss, claim,
damage or liability results from the fact that any Underwriter sold Preferred
Securities to a person as to whom it shall be established that there was not
sent or given, at or prior to the written confirmation of such sale, a copy of
the Prospectus as supplemented or amended and the loss, claim, damage or
liability of such Underwriter results from an untrue statement or omission of a
material fact contained in the preliminary prospectus or amendment or supplement
thereto which was corrected in the Prospectus or in the Prospectus as then
amended or supplemented and such correction would have cured the defect giving
rise to such loss, claim, damage or liability.

         (b) INDEMNIFICATION OF TRUST BY COMPANY. The Company agrees to
indemnify the Trust against all loss, liability, claim, damage and expense
whatsoever as due from the Trust under Section 6(a) hereunder.

         (c) INDEMNIFICATION OF TRUST, COMPANY, DIRECTORS AND OFFICERS. Each
Underwriter severally agrees to indemnify and hold harmless the Company and the
Trust, the Company's directors, each of the Company's officers and the Trustees
of the Trust who signed the Registration Statement, and each person, if any, who
controls the Company and the Trust within the meaning of Section 15 of the 1933
Act or Section 20 of the 1934 Act against any and all loss, liability, claim,
damage and expense described in the indemnity contained in subsection (a) of
this Section, as incurred, but only with respect to untrue statements or
omissions, or alleged untrue statements or omissions, made in the Registration
Statement (or any amendment thereto), or any preliminary prospectus or the
Prospectus (or any amendment or supplement thereto) in reliance upon and in
conformity with written information furnished to the Company by such Underwriter
through Morgan Stanley & Co. Incorporated expressly for use in the Registration
Statement (or any amendment thereto) or such preliminary prospectus or the
Prospectus (or any amendment or supplement thereto).

         (d) ACTIONS AGAINST PARTIES; NOTIFICATION. Each indemnified party shall
give notice as promptly as reasonably practicable to each indemnifying party of
any action commenced against it in respect of which indemnity may be sought
hereunder, but failure to so notify an indemnifying party shall not relieve such
indemnifying party from any liability hereunder to the extent it is not
materially prejudiced as a result thereof and in any event shall not relieve it
from any liability which it may have otherwise than on account of this indemnity
agreement. In the case of parties indemnified


                                       21


pursuant to Section 6(a) above, counsel to the indemnified parties shall be
selected by Morgan Stanley & Co. Incorporated, and, in the case of parties
indemnified pursuant to Section 6(c) above, counsel to the indemnified parties
shall be selected by the Company. An indemnifying party may participate at its
own expense in the defense of any such action; PROVIDED, HOWEVER, that counsel
to the indemnifying party shall not (except with the consent of the indemnified
party) also be counsel to the indemnified party. In no event shall the
indemnifying parties be liable for fees and expenses of more than one counsel
(in addition to any local counsel) separate from their own counsel for all
indemnified parties in connection with any one action or separate but similar or
related actions in the same jurisdiction arising out of the same general
allegations or circumstances. No indemnifying party shall, without the prior
written consent of the indemnified parties, settle or compromise or consent to
the entry of any judgment with respect to any litigation, or any investigation
or proceeding by any governmental agency or body, commenced or threatened, or
any claim whatsoever in respect of which indemnification or contribution could
be sought under this Section 6 or Section 7 hereof (whether or not the
indemnified parties are actual or potential parties thereto), unless such
settlement, compromise or consent (i) includes an unconditional release of each
indemnified party from all liability arising out of such litigation,
investigation, proceeding or claim and (ii) does not include a statement as to
or an admission of fault, culpability or a failure to act by or on behalf of any
indemnified party.

         (e) SETTLEMENT WITHOUT CONSENT IF FAILURE TO REIMBURSE. If at any time
an indemnified party shall have requested an indemnifying party to reimburse the
indemnified party for fees and expenses of counsel, such indemnifying party
agrees that it shall be liable for any settlement of the nature contemplated by
Section 6(a)(ii) effected without its written consent if (i) such settlement is
entered into more than 45 days after receipt by such indemnifying party of the
aforesaid request, (ii) such indemnifying party shall have received notice of
the terms of such settlement at least 30 days prior to such settlement being
entered into and (iii) such indemnifying party shall not have reimbursed such
indemnified party in accordance with such request prior to the date of such
settlement.

         SECTION 7. CONTRIBUTION. If the indemnification provided for in Section
6 hereof is for any reason unavailable to or insufficient to hold harmless an
indemnified party in respect of any losses, liabilities, claims, damages or
expenses referred to therein; then each indemnifying party shall contribute to
the aggregate amount of such losses, liabilities, claims, damages and expenses
incurred by such indemnified party, as incurred, (i) in such proportion as is
appropriate to reflect the relative benefits received by the Company and the
Trust on the one hand and the Underwriters on the other hand from the offering
of the Preferred Securities pursuant to this Agreement or (ii) if the allocation
provided by clause (i) is not permitted by applicable law, in such proportion as
is appropriate to reflect not only the relative benefits referred to in clause
(i) above but also the relative fault of the Company and the Trust on the one
hand and of the Underwriters on the other hand in connection with the statements
or omissions, which resulted in such losses, liabilities, claims, damages or
expenses, as well as any other relevant equitable considerations.

         The relative benefits received by the Company and the Trust on the one
hand and the Underwriters on the other hand in connection with the offering of
the Preferred Securities pursuant to this Agreement shall be deemed to be in the
same respective proportions as the total net proceeds from the offering of the
Preferred Securities pursuant to this Agreement (before deducting expenses)
received by the Company and the total underwriting commission received


                                       22


by the Underwriters, in each case as set forth on the cover of the Prospectus,
bear to the aggregate initial public offering price of the Securities as set
forth on such cover.

         The relative fault of the Company and the Trust on the one hand and the
Underwriters on the other hand shall be determined by reference to, among other
things, whether any such untrue or alleged untrue statement of a material fact
or omission or alleged omission to state a material fact relates to information
supplied by the Company or by the Underwriters and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission.

         The Company, the Trust and the Underwriters agree that it would not be
just and equitable if contribution pursuant to this Section 7 were determined by
pro rata allocation (even if the Underwriters were treated as one entity for
such purpose) or by any other method of allocation which does not take account
of the equitable considerations referred to above in this Section 7. The
aggregate amount of losses, liabilities, claims, damages and expenses incurred
by an indemnified party and referred to above in this Section 7 shall be deemed
to include any legal or other expenses reasonably incurred by such indemnified
party in investigating, preparing or defending against any litigation, or any
investigation or proceeding by any governmental agency or body, commenced or
threatened, or any claim whatsoever based upon any such untrue or alleged untrue
statement or omission or alleged omission.

         Notwithstanding the provisions of this Section 7, no Underwriter shall
be required to contribute any amount in excess of the amount by which the total
price at which the Securities underwritten by it and distributed to the public
were offered to the public exceeds the amount of any damages which such
Underwriter has otherwise been required to pay by reason of any such untrue or
alleged untrue statement or omission or alleged omission.

         No person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the 1933 Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

         For purposes of this Section 7, each person, if any, who controls an
Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of
the 1934 Act shall have the same rights to contribution as such Underwriter, and
each director of the Company, each officer of the Company and the Trustees of
the Trust who signed the Registration Statement, and each person, if any, who
controls the Company or the Trust within the meaning of Section 15 of the 1933
Act or Section 20 of the 1934 Act shall have the same rights to contribution as
the Company. The Underwriters' respective obligations to contribute pursuant to
this Section 7 are several in proportion to the number of Initial Preferred
Securities set forth opposite their respective names in Schedule A hereto and
not joint.


                                       23


         SECTION 8. REPRESENTATIONS, WARRANTIES AND AGREEMENTS TO SURVIVE
DELIVERY. All representations, warranties and agreements contained in this
Agreement or in certificates of officers of the Company or the Trustees of the
Trust or any of its other subsidiaries submitted pursuant hereto, shall remain
operative and in full force and effect, regardless of any investigation made by
or on behalf of any Underwriter or controlling person, or by or on behalf of the
Company, and shall survive delivery of the Preferred Securities to the
Underwriters.

         SECTION 9. TERMINATION OF AGREEMENT.

         (a) TERMINATION; GENERAL. The Representatives may terminate this
Agreement, by notice to the Company and the Trust, at any time at or prior to
Closing Time or any relevant Date of Delivery (i) if there has been, since the
time of execution of this Agreement, any material adverse change in the
condition, financial or otherwise, or in the earnings, business affairs or
business prospects of the Company and its subsidiaries considered as one
enterprise, whether or not arising in the ordinary course of business, or (ii)
if there has occurred any material adverse change in the financial markets in
the United States or the international financial markets, any outbreak of
hostilities or escalation thereof or other calamity or crisis or any material
adverse change or development involving a prospective material adverse change in
national or international political, financial or economic conditions, in each
case of subclauses (i) and (ii) above the effect of which is such as to make it,
in the judgment of the Representatives, impracticable to market the Preferred
Securities or to enforce contracts for the sale of the Preferred Securities, or
(iii) if trading in any securities of the Company has been suspended or
materially limited by the Commission or the New York Stock Exchange, or if
trading generally on the American Stock Exchange or the New York Stock Exchange
or in the Nasdaq National Market has been suspended or materially limited, or
minimum or maximum prices for trading have been fixed, or maximum ranges for
prices have been required, by any of said exchanges or by such system or by
order of the Commission, the National Association of Securities Dealers, Inc. or
any other governmental authority, or (iv) if a banking moratorium has been
declared by either Federal or New York authorities, or (v) if a material
disruption has occurred in commercial banking or securities settlement or
clearance services in the United States or with respect to Clearstream or
Euroclear systems in Europe.

         (b) LIABILITIES. If this Agreement is terminated pursuant to this
Section, such termination shall be without liability of any party to any other
party except as provided in Section 4 hereof, and provided further that Sections
1, 6, 7 and 8 shall survive such termination and remain in full force and
effect.


                                       24


         SECTION 10. DEFAULT BY ONE OR MORE OF THE UNDERWRITERS. If one or more
of the Underwriters shall fail at Closing Time or the relevant Date of Delivery,
as the case may be, to purchase the Preferred Securities which it or they are
obligated to purchase under this Agreement (the "Defaulted Securities"), the
Representatives shall have the right, within 24 hours thereafter, to make
arrangements for one or more of the non-defaulting Underwriters, or any other
underwriters, to purchase all, but not less than all, of the Defaulted
Securities in such amounts as may be agreed upon and upon the terms herein set
forth; if, however, the Representatives shall not have completed such
arrangements within such 24-hour period, then:

         (a) if the number of Defaulted Securities does not exceed 10% of the
number of Preferred Securities to be purchased on such date, each of the
non-defaulting Underwriters shall be obligated, severally and not jointly, to
purchase the full amount thereof in the proportions that their respective
underwriting obligations hereunder bear to the underwriting obligations of all
non-defaulting Underwriters, or

         (b) if the number of Defaulted Securities exceeds 10% of the number of
Preferred Securities to be purchased on such date, this Agreement or, with
respect to any Date of Delivery which occurs after Closing Time, the obligation
of the Underwriters to purchase and of the Trust to sell the Option Preferred
Securities to be purchased and sold on such Date of Delivery shall terminate
without liability on the part of any non-defaulting Underwriter.

         No action taken pursuant to this Section shall relieve any defaulting
Underwriter from liability in respect of its default.

         In the event of any such default which does not result in a termination
of this Agreement or, in the case of a Date of Delivery which is after the
Closing Time, which does not result in a termination of the obligation of the
Underwriters to purchase and the Trust to sell the relevant Option Preferred
Securities, as the case may be, either the non-defaulting Representative or the
Company shall have the right to postpone Closing Time or the relevant Date of
Delivery, as the case may be, for a period not exceeding seven days in order to
effect any required changes in the Registration Statement or Prospectus or in
any other documents or arrangements. As used herein, the term "Underwriter"
includes any person substituted for an Underwriter under this Section.


                                       25

shall be construed to give any person, firm or corporation, other than the

Morgan Stanley & Co. Incorporated,
Merrill Lynch & Co.,
Merrill Lynch, Pierce, Fenner & Smith Incorporated and
Salomon Smith Barney Inc.
         as Representatives of the several Underwriters named in
         Schedule A to the Underwriting Agreement described herein,
c/o Morgan Stanley & Co. Incorporated
1585 Broadway
New York, New York  10036


Re:      NorthWestern Corporation - 8.10% Trust Preferred Securities of
         NorthWestern Capital Financing III

Ladies and Gentlemen:

We have acted as counsel to NorthWestern Corporation, a Delaware corporation
(the "COMPANY"), and NorthWestern Capital Financing III, a Delaware statutory
business trust (the "TRUST"), with respect to the preparation of, and the
consummation of the transactions contemplated by, the Underwriting Agreement
(the "UNDERWRITING AGREEMENT"), dated as of January 24, 2002, among the Company,
the Trust and Morgan Stanley & Co. Incorporated, Merrill Lynch & Co., Merrill
Lynch, Pierce, Fenner & Smith Incorporated and Salomon Smith Barney Inc., as
Representatives of the several Underwriters named in Schedule A thereto
(collectively, the "UNDERWRITERS"), with respect to the issue and sale by the
Trust and the purchase by the Underwriters of an aggregate of 4,000,000 shares
of the Trust's 8.10% Trust Preferred Securities (liquidation amount $25 per
trust preferred security) (the "PREFERRED SECURITIES"). In connection with the
issue and sale by the Trust of the Preferred Securities, the Company has entered
into an Amended and Restated Declaration of Trust of the Trust, dated as January
31, 2002 (including Annex I and Annex II thereto, the "DECLARATION"), among the

In rendering this opinion we have made the following assumptions, each without
any investigation or independent verification, except as otherwise noted, and
our opinion is subject to the qualifications set forth below.

Insofar as the opinions expressed in paragraphs 1, 2 and 5 below relate to the
Trust or the Trustees or matters which are governed by the Delaware Business
Trust Act, we have relied with your permission solely upon the opinion of
Richards, Layton & Finger, P.A., a copy of which is attached hereto, without any
independent investigation by us in accordance with the Legal Opinion Accord of
the American Bar Association.

We have assumed the genuineness of all signatures, the authenticity and
completeness of all documents, certificates and instruments submitted to us as
originals, the conformity with the originals of all documents, certificates and
instruments submitted to us as copies, the authenticity and completeness of such
underlying originals and the legal capacity of all individuals executing such
documents, certificates and instruments.

We have assumed that there are no oral modifications or written agreements or
understandings which limit, modify or otherwise alter the terms, provisions, and
conditions of, or relate to, the transactions contemplated by the Financing
Agreements.

As to matters of fact relevant or material to this opinion, we have relied
without independent investigation on, and assumed the accuracy and completeness
of, the Certificates and the representations and warranties of each party made
in the Financing Agreements. We have not made an investigation as to, and have
not independently verified, the facts underlying the matters covered by the
Certificates or such representations and warranties.

The phrases "to our knowledge," "known to us" and the like mean to the current
actual knowledge of the attorneys of this Firm who have actively and directly
participated in the negotiation and closing of, and who devoted substantive
attention to, the transactions contemplated by the Financing Agreements. Where
matters are stated to be "to our knowledge," "known to us" or the like, our
investigations consisted only of an inquiry of the officers of the Company and
the Trustees of the Trust, the results of which are reflected in the
Certificates, and a review of the Financing Agreements, and known to us by
virtue of our representation of the Company and the Trust with respect to the
transactions contemplated by the Financing Agreements. We have not made any
investigation of other attorneys of this Firm, of our files or as to the facts
underlying the matters covered by the Certificates or the Financing Agreements.

We also have assumed (a) the due authorization, execution, acknowledgement as
indicated thereon and delivery of documents recited herein or delivered at the
closing (including the Financing Agreements) by each party thereto (other than
the Company and the Trust), that each party (other than the Company and the
Trust) has taken all other acts necessary for the performance of its obligations
under the Financing Agreements, and the validity, binding effect and
enforceability thereof, against each party thereto other than the Company and
the Trust, (b) that, with respect to all parties (other than the Company and the
Trust), each party is validly existing and has full power, authority and legal
right to execute and deliver the Financing Agreements to which it is a party and
to carry out the transactions contemplated thereunder, and that each is duly
qualified and in good standing in each jurisdiction where qualification is




                                     A-1-4
<Page>

required to the extent that any of the opinions expressed herein would be
affected by the failure to so qualify and (c) that each party (other than the
Company and the Trust), has complied with any order, rule, regulation or law
which may be applicable to such party with regard to any aspect of the
transactions contemplated by the Financing Agreements to the extent that any of
the opinions expressed herein would be affected by the failure to so comply.

Statements in this opinion as to the validity, binding effect and enforceability
are subject to the following qualifications (a) they are limited by applicable
bankruptcy, insolvency, reorganization, fraudulent conveyance and transfer,
moratorium or other laws now or hereafter in effect relating to or affecting the
rights or remedies of creditors generally and by general principles of equity
(whether applied in a proceeding at law or in equity) including, without
limitation, standards of materiality, good faith and reasonableness in the
interpretation and enforcement of contracts, and the application of such
principles to limit the availability of equitable remedies such as specific
performance and (b) with reference to, but without limiting in any way,
qualification (a) above, provisions indemnifying a party against liability for
its own wrongful or negligent acts or otherwise in cases where indemnification
could be considered contrary to public policy (including, without limitation,
under federal and state securities laws and regulations as interpreted by
applicable governmental authorities), provisions waiving defenses or other
rights and provisions to the effect that terms of the documents may not be
waived or modified except in writing, are or may be unenforceable in whole or in
part under applicable law; however, subject to the other qualifications stated
herein, such unenforceability will not, in our opinion, make the remedies
afforded by the Underwriting Agreement, the Guarantee Agreements, the
Declaration, the Indenture and the Debentures, taken as a whole, inadequate for
the practical realization of remedies upon a default by the Company or the
Trust.

We are members of the Bar of the State of New York and our opinions herein are
limited to the laws of the State of New York, the General Corporation Law of the
State of Delaware (based solely on our review of a standard compilation of such
law) and the federal law of the United States, and we do not express any opinion
as to the laws of any other state or jurisdiction. No opinion is expressed as to
choice of law provisions contained in the Financing Agreements. No opinion is
expressed as to the effect that the law of any other jurisdiction might have
upon the subject matter of the opinions expressed herein under conflicts of laws
principles or otherwise. We express no opinion as to any county, municipal,
city, town or village ordinance, rule or regulation. Except for the opinions in
paragraphs 8, 10, 11 and 13 hereof, we express no opinion herein with respect to
the application of or compliance with any federal or state securities or blue
sky laws or regulations (including, without limitation, any filing or notice
requirements thereunder), and for purposes of this opinion have assumed
compliance by all parties with such laws and regulations.

We express no opinion except as expressly set forth in the numbered paragraphs
below and no opinions shall be implied. We express no opinion as to
environmental laws, antitrust or unfair competition laws or the law of fiduciary
duty, or the rules and regulations promulgated thereunder. We disclaim any
obligation to update any of the opinions expressed herein for events (including
changes of law or fact) occurring after the date hereof.

Based upon and subject to the assumptions, exceptions, qualifications and
limitations set forth herein, we are of the opinion that:



                                     A-1-5

1.       The Preferred Securities have been duly authorized by the Declaration
         and, when issued, executed, authenticated, delivered and paid for in
         accordance with the Declaration and the Underwriting Agreement, will be
         validly issued, fully paid and, subject to the qualification set forth
         below, non-assessable undivided beneficial interests in the assets of
         the Trust. Under the Declaration and the Delaware Business Trust Act,
         each holder of Preferred Securities, in such capacity, will be entitled
         to the same limitation on personal liability extended to stockholders
         of private corporations for profit organized under the General
         Corporation Law of the State of Delaware; provided, however, we express
         no opinion with respect to the liability of any holder of Preferred
         Securities who is, was or may become a named Trustee of the Trust.
         Notwithstanding the foregoing, we note that, pursuant to the
         Declaration, holders of Preferred Securities may be obligated to make
         payments or provide indemnity or security under the circumstances set
         forth therein.

2.       Under the Declaration and the Delaware Business Trust Act, the
         execution and the delivery by the Trust of the Underwriting Agreement,
         have been duly authorized by all requisite trust action on the part of
         the Trust.

3.       The Underwriting Agreement has been duly authorized, executed and
         delivered by the Company.

4.       The Guarantee Agreements have been duly authorized, executed and
         delivered by the Company and are valid and binding obligations of the
         Company, enforceable against the Company in accordance with their
         terms.

5.       The Declaration has been duly authorized, executed and delivered by the
         Company and constitutes a legal valid and binding obligation of the
         Company and each of the Trustees, and is enforceable against the
         Company and each of the Trustees in accordance with its terms.

6.       The Indenture has been duly authorized, executed and delivered by the
         Company and constitutes a valid and binding obligation of the Company,
         enforceable against the Company in accordance with its terms.

7.       The Debentures have been duly authorized and executed by the Company
         and, when the Debentures have been duly authenticated by the Debenture
         Trustee in accordance with the provisions of the Indenture and
         delivered against payment of the purchase price as described in the
         Prospectus, the Debentures will constitute valid and binding
         obligations of the Company entitled to the benefits of the Indenture
         and enforceable against the Company in accordance with their terms.

8.       The Indenture, the Preferred Securities Guarantee Agreement and the
         Declaration have each been duly qualified under the 1939 Act.

9.       The execution, delivery and performance of the Underwriting Agreement,
         the Declaration, the Indenture and the Guarantee Agreements and
         compliance by the Company with its obligations thereunder do not and
         will not, whether with or without the giving of notice or lapse of time
         or both, (a) violate or result in the violation of the Certificate of
         Incorporation or By-Laws of the Company existing on the date hereof or


                                     A-1-6
<Page>

         (b) violate or result in the violation of any applicable law, statute,
         rule, regulation, judgment, writ, order or decree known to us of either
         the federal or New York government or any government instrumentality
         thereof existing on the date hereof and having jurisdiction over the
         Company or any of its properties or assets of which we are aware (other
         than state securities or blue sky laws, as to which we express no
         opinion and other than federal securities laws, as to which we express
         no opinion in this paragraph).

10.      Based upon the oral advice of the Commission, the Registration
         Statement has been declared effective under the 1933 Act; any required
         filing of the Prospectus pursuant to Rule 424(b) has been made in the
         manner and within the time period required by Rule 424(b); and we are
         not aware, after due inquiry, of any stop order suspending the
         effectiveness of the Registration Statement and, to our knowledge, no
         proceedings for that purpose have been initiated or are pending or
         overtly threatened by the Commission.

11.      The Registration Statement, the Prospectus, and each amendment or
         supplement to the Registration Statement and the Prospectus (excluding
         the documents incorporated by reference in each of the foregoing), as
         of their respective effective or issue dates (except for the financial
         statements, notes and schedules thereto, the other financial,
         accounting and statistical data derived from the internal financial
         records of the Company included or incorporated by reference therein or
         omitted therefrom and Exhibit 25 to the Registration Statement, as to
         which it is understood we express no opinion) comply as to form in all
         material respects with the requirements of the 1933 Act and the 1933
         Act Regulations.

12.      The statements set forth in the Prospectus under the captions
         "Description of the Trust Preferred Securities," "Description of the
         Subordinated Debentures," "Description of the Preferred Securities
         Guarantee," "Description of the Trusts' Preferred Securities,"
         "Description of the Guarantees" and "Relationship Among the Preferred
         Securities, the Subordinated Debt Securities and the Guarantees," the
         information relating to the Subordinated Debt Securities (as defined in
         the Prospectus) under the caption "Description of Debt Securities"
         (other than the information described under "Description of Debt
         Securities--Option to Accelerate Maturity Date") and the information
         contained under Item 15 in the Registration Statement insofar as they
         purport to constitute a summary of matters of law, legal matters or the
         By-Laws, are correct summaries in all material respects.

13.      Neither the Company nor the Trust is, and upon the issuance and sale of
         the Preferred Securities as herein contemplated and the application of
         the net proceeds therefrom as described in the Prospectus neither will
         be, required to be registered under the Investment Company Act of 1940,
         as amended.

14.      The FERC has issued appropriate authorizations with respect to the
         issuance of the Guarantees and the Debentures in accordance with the
         Indenture, the Preferred Securities Guarantee Agreement and the Common
         Securities Guarantee Agreement; to our knowledge, after due inquiry,
         such authorizations are in full force and effect and the issuance of
         the Guarantees and the Debentures are in conformity with the terms of
         such authorizations, and no other authorization, approval or consent,
         or other action by or



                                     A-1-7
<Page>

         filing with any New York or federal governmental authority or agency
         or, to our knowledge, any New York or federal court, not already
         obtained, is legally required for the issuance and sale of the
         Securities as contemplated by the Financing Agreements, except such as
         may have been obtained under the 1933 Act, the 1934 Act, the 1939 Act
         and such as may be required under state securities or blue sky laws (as
         to which we express no opinion).

We have participated in conferences with directors, officers and other
representatives of the Company, the Trustees and other representatives of the
Trust, representatives of the independent public accountants for the Company and
the Trust, representatives of the Underwriters and representatives of counsel
for the Underwriters, at which conferences the contents of the Registration
Statement and the Prospectus and related matters were discussed. Although we
have reviewed the documents incorporated by reference in the Registration
Statement and the Prospectus, we did not participate in their preparation. In
addition, we did not undertake to determine or verify independently and,
therefore, are not passing upon and do not assume any responsibility, explicitly
or implicitly, for the accuracy, completeness or fairness of the statements
contained in the Registration Statement or the Prospectus (except to the extent
specified in paragraph 12 above). Based upon and subject to the foregoing, no
facts have come to our attention that have caused us to believe that, the
Registration Statement, on the effective date thereof, contained an untrue
statement of a material fact or omitted to state a material fact required to be
stated therein or necessary to make the statements contained therein not
misleading or that the Prospectus, on the date thereof or on the date hereof,
contained or contains an untrue statement of a material fact or omitted or omits
to state a material fact required to be stated therein or necessary to make the
statements contained therein, in light of the circumstances under which they
were made, not misleading (it being understood that we express no view with
respect to the financial statements, notes and schedules thereto, the other
financial, accounting and statistical data derived from the internal financial
records of the Company included or incorporated by reference therein or omitted
therefrom and Exhibit 25 to the Registration Statement).

The opinions and views expressed herein are solely for the information of the
addressees in connection with the transactions contemplated by the Financing
Agreements, and may not be relied upon in any other context or by any other
person, firm or entity, or relied upon or quoted in whole or part or otherwise
referred to for any other purpose, nor is it to be delivered to, filed with, or
furnished or disclosed to any governmental agency or other person, firm or
entity without our prior express written consent.

Re:      NorthWestern Corporation - 8.10% Trust Preferred Securities of

Ladies and Gentlemen:

We have acted as special tax counsel to NorthWestern Corporation, a Delaware

Trust and the purchase by the Underwriters of an aggregate of 4,000,000 shares

into an Amended and Restated Declaration of Trust of the Trust, dated as of

"TRUSTEES") and the holders, from time to time, of beneficial interests in the
assets of the Trust, pursuant to which the Company has agreed to purchase an
aggregate of 123,712 shares of the Trust's 8.10% Trust Common Securities
(liquidation amount $25 per trust common security) (the "COMMON SECURITIES"). In
connection with the issue and sale of the Preferred Securities and the Common
Securities, the Company has entered into a Preferred Securities Guarantee
Agreement, dated as of January 31, 2002 (the "PREFERRED SECURITIES GUARANTEE

rendered at the request of the Company and the Trust pursuant to Section 5(b)(i)
of the Underwriting Agreement. Except as otherwise defined herein, capitalized
terms used in this opinion letter are defined as set forth in the Underwriting
Agreement..

In rendering this opinion, we have examined originals or copies of the

         (ii)     the Preferred Securities Guarantee Agreement and the Common
                  Securities Guarantee Agreement;

                  1, 1995 (the "BASE INDENTURE"), between the Company and
                  JPMorgan Chase Bank, as successor to The Chase Manhattan Bank,
                  N.A., as trustee (the "DEBENTURE TRUSTEE"), and the Fourth
                  Supplemental Indenture, dated as of January 31, 2002 (the
                  "SUPPLEMENTAL INDENTURE" and, together with the Base
                  Indenture, the "INDENTURE" and, collectively with the
                  Underwriting Agreement, the Guarantee Agreements, the
                  Preferred Securities and the Common Securities, the "FINANCING
                  AGREEMENTS"), between the Company and the Debenture Trustee;
                  and

         (iv)     the form of the Preferred Securities, the form of the Common
                  Securities and the form of the Debentures;

(e)      the Registration Statements on Form S-3 (Nos. 333-58491 and 333-82707)
         filed by the Company and the Trust with the Securities and Exchange
         Commission (the "Commission") under the 1933 Act (together, the
         "REGISTRATION STATEMENT") and the prospectus included in the
         Registration Statement, as supplemented to reflect the terms of the
         Preferred Securities and the terms of the offering of the Preferred
         Securities pursuant to the Underwriting Agreement, as filed with the
         Commission (the "PROSPECTUS"); and

(f)      such other documents and records as we have deemed necessary for
         purposes of this opinion;



                                     A-2-2
<Page>

         In our examination, we have assumed that (i) the statements concerning
the issuance of the Preferred Securities and Debentures referred to in the
Registration Statement and Prospectus are true, correct and complete, (ii) the
terms of the documents listed in the preceding paragraph will be complied with,
(iii) the factual representations made to us by the Company in its letter to us
dated as of the date hereof and delivered to us for purposes of this opinion
(the "Representation Letter") are true, correct and complete and (iv) any
factual representations made in the Registration Statements, Prospectus or the
Representation Letter "to the best knowledge of" or similarly qualified are
true, correct and complete without such qualification.

         Based solely upon the foregoing, we are of the opinion that under
current United States federal income tax law:

1.       The Debentures will be classified for United States federal income tax
         purposes as indebtedness of the Company.

2.       The Trust will be classified for United States federal income tax
         purposes as a grantor trust and not as an association subject to tax as
         a corporation.

3.       Although the discussion set forth in the Prospectus under the heading
         "Certain United States Federal Income Tax Consequences" does not
         purport to discuss all possible United States federal income tax
         consequences of the purchase, ownership, and disposition of Preferred
         Securities, such discussion constitutes, in all material respects, a
         fair and accurate summary of the United States federal income tax
         consequences of the purchase, ownership, and disposition of Preferred
         Securities under current law.

Our opinion is limited to the tax matters specifically covered hereby. Our
opinion is based upon current statutory, regulatory and judicial authority, any
of which may be changed at any time with retroactive effect. We disclaim any
undertaking to advise you of any subsequent changes of the matters stated,
represented or assumed herein or any subsequent changes in applicable law,
regulations or interpretations thereof. Without our prior written consent, this
opinion may not be furnished or quoted to, or relied upon by, any other persons
for any purpose.

Very truly yours,

                                      B-3

In rendering this opinion I have made the following assumptions, each without
any investigation or independent verification, except as otherwise noted, and my
opinion is subject to the qualifications set forth below.

I have assumed the genuineness of all signatures, the authenticity and
completeness of all documents, certificates and instruments submitted to me as
originals, the conformity with the originals of all documents, certificates and
instruments submitted to me as copies, the authenticity and completeness of such
underlying originals and the legal capacity of all individuals executing such
documents, certificates and instruments.

I have assumed that there are no oral modifications or written agreements or
understandings which limit, modify or otherwise alter the terms, provisions, and
conditions of, or relate to, the transactions contemplated by the Financing
Agreements.

As to matters of fact relevant or material to this opinion, I have relied
without independent investigation on, and assumed the accuracy and completeness
of, the Certificates and the representations and warranties of each party made
in the Financing Agreements. I have not made an investigation as to, and have
not independently verified, the facts underlying the matters covered by the
Certificates or such representations and warranties.

The phrases "to my knowledge," "known to me" and the like mean to my current
actual knowledge and the current actual knowledge of members of my staff who
have actively and directly participated in the negotiation and closing of, and
who devoted substantive attention to, the transactions contemplated by the
Financing Agreements. Where matters are stated to be "to my knowledge," "known
to me" or the like, my investigations consisted only of an inquiry of the
officers of the Company and the Trustees of the Trust, the results of which are
reflected in the Certificates, and a review of the Financing Agreements, and
known to me in my capacity as Vice President - Legal Administration of the
Company and by virtue of my representation of the Company and the Trust with
respect to the transactions contemplated by the Financing Agreements. I have not
made any investigation of other employees of the Company or the Trustees of the
Trust, of the Company's or the Trust's files or as to the facts underlying the
matters covered by the Certificates or the Financing Agreements.

I am a member of the Bar of the States of South Dakota and Nebraska, and my
opinions herein are limited to the laws of those States, the General Corporation
Law of the State of Delaware (based solely on my review of a standard
compilation of such laws) and the federal law of the United States, and I do not
express any opinion as to the laws of any other state or jurisdiction. No
opinion is expressed as to the effect that the law of any other jurisdiction
might have upon the subject matter of the opinions expressed herein under
conflicts of laws principles or otherwise. I express no opinion as to any
county, municipal, city, town or village ordinance, rule or regulation. Except
for my opinion in paragraph 13 hereof, I express no opinion herein with respect
to the application of or compliance with any federal or state securities or blue
sky laws or regulations (including, without limitation, any filing or notice
requirements thereunder), and for purposes of this opinion have assumed
compliance by all parties with such laws and regulations.



                                      B-4
<Page>

I express no opinion except as expressly set forth in the numbered paragraphs
below and no opinions shall be implied. I express no opinion as to environmental
laws, antitrust or unfair competition laws or the law of fiduciary duty, or the
rules and regulations promulgated thereunder. I disclaim any obligation to
update any of the opinions expressed herein for events (including changes of law
or fact) occurring after the date hereof.

Based upon and subject to the assumptions, exceptions, qualifications and
limitations set forth herein, I am of the opinion that:

1.       The Company has been duly incorporated and is validly existing as a
         corporation in good standing under the laws of the state of Delaware.

2.       The Company has all requisite corporate power and authority to own,
         lease and operate its properties and to conduct its business as
         described in the Prospectus and to enter into and perform its
         obligations under the Underwriting Agreement, the Declaration, the
         Indenture and the Guarantee Agreements.

3.       The Company is authorized as a domesticated foreign corporation to
         transact business, and is in good standing, in the State of Nebraska
         and is duly qualified as a foreign corporation to transact business and
         is in good standing in each jurisdiction in which such qualification is
         required, whether by reason of the ownership or leasing of property or
         the conduct of business, except where the failure so to qualify or to
         be in good standing would not result in a Material Adverse Effect.

4.       The authorized, issued and outstanding capital stock of the Company is
         as set forth in the Prospectus in the column entitled "Actual" under
         the caption "Capitalization" (except for the Company's issuance of 3.68
         million shares of common stock in October 2001 and subsequent
         issuances, if any, pursuant to the Underwriting Agreement, pursuant to
         reservations, agreements or employee benefit plans referred to in the
         Prospectus or pursuant to the exercise of convertible securities or
         options referred to in the Prospectus).

5.       Each Subsidiary has been duly organized or formed and is validly
         existing as a corporation or a limited partnership, as the case may be,
         in good standing under the laws of its jurisdiction of incorporation or
         organization, has corporate or partnership power and authority to own,
         lease and operate its properties and to conduct its business as
         described in the Prospectus and is duly qualified as a foreign
         corporation or limited partnership to transact business and is in good
         standing in each jurisdiction in which such qualification is required,
         whether by reason of the ownership or leasing of property or the
         conduct of business, except where the failure so to qualify or to be in
         good standing would not result in a Material Adverse Effect.

6.       Except as otherwise disclosed in the Registration Statement, all of the
         issued and outstanding shares of capital stock or partnership
         interests, as the case may be, of each Subsidiary have been duly
         authorized and validly issued, are fully paid and non-assessable and,
         based solely on a review of the limited partnership agreement of
         CornerStone, the stock ledger of each of the other Subsidiaries and the
         Certificates, to my knowledge, all of the capital stock or limited
         partnership interests, as the case may be, of


                                      B-5
<Page>

         each Subsidiary owned by the Company, directly or through subsidiaries,
         is owned free and clear of any security interest, mortgage, pledge,
         lien, encumbrance, claim or equity. None of the outstanding shares of
         capital stock or partnership interests of any Subsidiary was issued in
         violation of the preemptive or similar rights of any security holder of
         such Subsidiary.

7.       To my knowledge, neither the Company nor any Subsidiary is in violation
         of its charter or by-laws and no default by the Company or any
         Subsidiary exists in the due performance or observance of any material
         obligation, agreement, covenant or condition contained in any contract,
         indenture, mortgage, loan agreement, note, lease or other agreement or
         instrument that is described or referred to in the Registration
         Statement or the Prospectus or filed or incorporated by reference as an
         exhibit to the Registration Statement.

8.       The execution, delivery and performance of the Underwriting Agreement,
         the Declaration of Trust, the Indenture and the Guarantee Agreements
         and the consummation of the transactions contemplated thereunder and in
         the Registration Statement (including the issuance and sale of the
         Securities and the use of the proceeds from the sale of the Securities
         as described in the Prospectus under the caption "Use Of Proceeds") and
         compliance by the Company with its obligations thereunder do not and
         will not, whether with or without the giving of notice or lapse of time
         or both, violate or constitute a breach of, or default or Repayment
         Event (as defined in Section 1(a)(xvii) of the Underwriting Agreement)
         under, or result in the creation or imposition of any lien, charge or
         encumbrance upon any property or assets of the Company or any
         Subsidiary pursuant to, any material contract, indenture, mortgage,
         deed of trust, loan or credit agreement, note, lease or any other
         agreement or instrument, known to me, to which the Company or any
         Subsidiary is a party or by which it or any of them may be bound, or to
         which any of the property or assets of the Company or any Subsidiary is
         subject (except for such violations, breaches or defaults or Repayment
         Events or liens, charges or encumbrances that would not have a Material
         Adverse Effect).

9.       The FERC has issued appropriate authorizations with respect to the
         issuance of the Guarantees and the Debentures in accordance with the
         Indenture, the Preferred Securities Guarantee Agreement and the Common
         Securities Guarantee Agreement; to my knowledge, after due inquiry,
         such authorizations are in full force and effect and the issuance of
         the Guarantees and the Debentures are in conformity with the terms of
         such authorizations; and no other authorization, approval or consent or
         other action by or filing with any South Dakota, Nebraska or federal
         governmental authority or agency or, to my knowledge, any South Dakota,
         Nebraska or federal court, not already obtained, is legally required
         for the issuance and sale of the Securities as contemplated by the
         Financing Agreements, except such as may have been obtained under the
         1933 Act, the 1934 Act, the 1939 Act and such as may be required under
         state securities or blue sky laws (as to which I express no opinion).

10.      Except as disclosed in the Registration Statement, to my knowledge,
         there is not pending or overtly threatened any action, suit,

         Subsidiary is a party, or to which the property of the Company or any
         Subsidiary is subject, before or brought by any court or governmental
         agency or body, domestic or foreign, which would result in a Material
         Adverse Effect, or which would materially and adversely affect the
         ability of the Company to consummate the transactions contemplated by
         the Underwriting Agreement.

11.      To my knowledge, there are no statutes or regulations that are required
         to be described in the Prospectus that are not described as required.

12.      To my knowledge, there are no material franchises, contracts,
         indentures, mortgages, loan agreements, notes, leases or other
         instruments required to be described or referred to in the Registration
         Statement or to be filed as exhibits thereto other than those described
         or referred to therein or filed or incorporated by reference as
         exhibits thereto, and insofar as any descriptions of such material
         franchises, contracts, indentures, mortgages, loan agreements, notes,
         leases or other instruments purport to constitute a summary of the
         terms thereof, such summaries are correct in all material respects.

13.      The documents incorporated by reference in the Prospectus (except for
         the financial statements, notes and schedules thereto, the other
         financial, accounting and statistical data derived from the internal
         financial records of the Company included or incorporated by reference
         therein or omitted therefrom and Exhibit 25 to the Registration
         Statement, as to which it is understood I express no opinion), when
         they were filed with the Commission, complied as to form in all
         material respects with the requirements of the 1933 Act or the 1934
         Act, as applicable, and the rules and regulations of the Commission
         thereunder.

I have participated in conferences with directors, officers and other
representatives of the Company, the trustees and other representatives of the
Trust, representatives of the independent public accountants for the Company and
the Trust, representatives of the Underwriters and representatives of counsel
for the Underwriters, at which conferences the contents of the Registration
Statement and the Prospectus and related matters were discussed and, although I
did not undertake to determine or verify independently and, therefore, am not
passing upon and do not assume any responsibility, explicitly or implicitly, for
the accuracy, completeness or fairness of the statements contained in the
Registration Statement or the Prospectus (except to the extent specified in
paragraph 12 above), no facts have come to my attention that have caused me to
believe that, the Registration Statement on the effective date thereof,
contained an untrue statement of a material fact or omitted to state a material
fact required to be stated therein or necessary to make the statements contained
therein not misleading or that the Prospectus, on the date thereof or on the
date hereof, contained or contains an untrue statement of a material fact or
omitted or omits to state a material fact required to be stated therein or
necessary to make the statements contained therein, in light of the
circumstances under which they were made, not misleading (it being understood
that I express no view with respect to the financial statements, notes and
schedules thereto, the other financial, accounting and statistical data derived
from the internal financial records of the Company included or incorporated by
reference therein or omitted therefrom and Exhibit 25 to the Registration
Statement).

The opinions and views expressed herein are solely for the information of the

                                                                       Exhibit C

                   FORM OF OPINION OF SPECIAL DELAWARE COUNSEL
                     FOR THE TRUST TO BE DELIVERED PURSUANT
                                 TO SECTION 5(c)


         (i) The Trust has been duly formed and is validly existing in good
standing as a business trust under the Delaware Act. All filings required under
the laws of the State of Delaware with respect to the formation and valid
existence of the Trust as a business trust have been made. Under the Declaration
and the Delaware Act, the Trust has the requisite business trust power and
authority to conduct its business, all as described in the Prospectus.

         (ii) The Declaration constitutes a legal, valid and binding obligation
of the Company and each of the Trustees, and is enforceable against the Company
and each of the Trustees, in accordance with its terms, except to the extent
that enforcement thereof may be limited by (i) bankruptcy, insolvency,
moratorium, receivership, reorganization, liquidation, fraudulent conveyance or
transfer and other similar laws relating to or affecting the rights and remedies
of creditors generally, (ii) principles of equity, including applicable law
relating to fiduciary duties (regardless of whether considered and applied in a
proceeding in equity or at law), and (iii) the effect of applicable public
policy on the enforceability of provisions relating to indemnification or
contribution.

         (iii) The Preferred Securities have been duly authorized by the
Declaration and, when issued, executed, authenticated, delivered and paid for in
accordance with the Declaration and the Purchase Agreement, will be validly
issued, fully paid and, subject to the qualifications set forth in paragraph
(iv) below, non-assessable undivided beneficial interests in the assets of the
Trust and will entitle the holders of the Preferred Securities to the benefits
of the Declaration except to the extent that enforcement of the Declaration may
be limited by (i) bankruptcy, insolvency, moratorium, receivership,
reorganization, liquidation, fraudulent conveyance or transfer and other similar
laws relating to or affecting the rights and remedies of creditors generally,
(ii) principles of equity, including applicable law relating to fiduciary duties
(regardless of whether considered and applied in a proceeding in equity or at
law), and (iii) the effect of applicable public policy on the enforceability of
provisions relating to indemnification or contribution. Under the Delaware Act
and the Declaration, the issuance of the Preferred Securities is not subject to
any preemptive or other similar rights.

         (iv) Under the Declaration and the Delaware Act, each Preferred
Security Holder of the Trust, in such capacity, will be entitled to the same
limitation on personal liability extended to stockholders of private
corporations for profit organized under the General Corporation Law of the State
of Delaware; provided, however, we express no opinion with respect to the
liability of any Preferred Security Holder who is, was or may become a named
Trustee of the Trust. Notwithstanding the foregoing, we note that, pursuant to
the Declaration, Preferred Security Holders may be obligated to make payments or
provide indemnity or security under the circumstances set forth therein.



                                       C-1


         (v) The Common Securities have been duly authorized for issuance by the
Declaration and, when issued, executed, authenticated, delivered and paid for in
accordance with the Declaration and the Common Securities Subscription
Agreement, will be validly issued, fully paid undivided beneficial interests in
the assets of the Trust and will entitle the holders of the Common Securities to
the benefits of the Declaration except to the extent that enforcement of the
Declaration may be limited by (i) bankruptcy, insolvency, moratorium,
receivership, reorganization, liquidation, fraudulent conveyance or transfer and
other similar laws relating to or affecting the rights and remedies of creditors
generally, (ii) principles of equity, including applicable law relating to
fiduciary duties (regardless of whether considered and applied in a proceeding
in equity or at law), and (iii) the effect of applicable public policy on the
enforceability of provisions relating to indemnification or contribution. Under
the Delaware Act and the Declaration, the issuance of the Preferred Securities
is not subject to any preemptive or other similar rights.

         (vi) Under the Declaration and the Delaware Act, the Trust has the
requisite business trust power and authority to execute and deliver the Purchase
Agreement and to perform its obligations under the Purchase Agreement and to
consummate the transactions contemplated thereby. Under the Declaration and the
Delaware Act, the execution and delivery by the Trust of the Purchase Agreement,
and the performance of its obligations thereunder, have been duly authorized by
all requisite trust action on the part of the Trust.

         (vii) We have reviewed the statements made in the Prospectus under the
captions "The Trusts" and "NorthWestern Capital Financing III" and, insofar as
they contain statements of Delaware law, such statements are fairly presented.

         (viii) No authorization, approval, consent or order of any Delaware
court or Delaware governmental authority or Delaware agency is required to be
obtained by the Trust solely as a result of the issuance and sale of the Trust
Securities.

         (ix) The issuance and sale by the Trust of the Trust Securities, the
execution, delivery and performance by the Trust of the Purchase Agreement and
the Declaration and compliance by the Trust with its obligations thereunder do
not violate (i) any provisions of the Declaration or (ii) any applicable
Delaware law or Delaware administrative regulation.
