    Northern States Power Company (the "Company") was incorporated in 1909 under
the  laws of Minnesota. Its executive offices  are located at 414 Nicollet Mall,
Minneapolis, Minnesota 55401. (Phone  612-330-5500). The Company's  subsidiaries
include  Northern States Power Company, an operating public utility incorporated
in  Wisconsin   ("NSP-Wisconsin"),  NRG   Energy,  Inc.   ("NRG"),  a   Delaware
corporation,  and  Viking  Gas  Transmission  Company,  a  Delaware  corporation
("Viking"). The Company and its subsidiaries collectively are referred to herein
as NSP.

    NSP is predominantly an operating public utility engaged in the  generation,
transmission  and distribution  of electricity  throughout a  49,000 square mile
service  area  and  the  distribution  of  natural  gas  in  approximately   148
communities  within this  area. Viking is  a regulated  natural gas transmission
company that  operates  a  500-mile  interstate natural  gas  pipeline.  NRG  is
primarily   engaged   in  managing   several   of  NSP's   non-regulated  energy
subsidiaries.

    The Company serves customers  in Minnesota, North  Dakota and South  Dakota.
NSP-Wisconsin  serves customers in Wisconsin  and Michigan. Of the approximately
three million people served by the  Company and NSP-Wisconsin, the majority  are
concentrated  in the Minneapolis-St.  Paul Metropolitan Area.  In 1994, about 61
percent of  NSP's  electric  retail  revenue  was  derived  from  sales  in  the
Minneapolis-St. Paul Metropolitan Area and about 56 percent of gas revenues came
from sales in the St. Paul area. NSP's electric generation for 1994 was provided
for  by  coal (59%),  nuclear (36%),  and  renewable and  other fuels  (5%). NSP
currently operates three nuclear units that were placed in service in 1971, 1973
and 1974. NSP has no additional nuclear units under construction.

                                PROPOSED MERGER

    The Company, Wisconsin Energy Corporation, a Wisconsin corporation  ("WEC"),
Northern  Power  Wisconsin  Corp.,  a  Wisconsin  corporation  and  wholly-owned
subsidiary  of  the  Company  ("New  NSP"),  and  WEC  Sub  Corp.,  a  Wisconsin
corporation and wholly-owned subsidiary of WEC ("WEC Sub"), have entered into an
Agreement  and Plan  of Merger, dated  as of April  28, 1995 and  as amended and
restated as of  July 26,  1995 (the "Merger  Agreement"), which  provides for  a
strategic  business combination  involving NSP  and WEC  in a "merger-of-equals"
transaction (the "Transaction"). The Transaction, which was unanimously approved
by the Boards  of Directors  of the constituent  companies and  approved by  the
shareholders of both the Company and WEC, is expected to close shortly after all
of  the conditions to  the consummation of  the Transaction, including obtaining
applicable regulatory  approvals, are  met or  waived. The  regulatory  approval
process is expected to take approximately 12 to 18 months from April 28, 1995.

    Additional  information concerning the Transaction and the Merger Agreement,
including pro forma combined financial information, is included in the Company's
Quarterly Report on Form 10-Q for the quarter ended June 30, 1995 and Amendments
thereto (on Form  10-Q/A) dated August  4, 1995  and August 7,  1995 (the  "Form
10-Q")  filed  with  the  Commission and  incorporated  by  reference  into this
Prospectus.

    In the Transaction, the holding company  of the combined enterprise will  be
registered under the Public Utility Holding Company Act of 1935, as amended. The
holding  company will be named Primergy Corporation ("Primergy") and will be the
parent company  of  both  the  Company  (which,  for  regulatory  reasons,  will
reincorporate  in Wisconsin) and of  WEC's present principal utility subsidiary,
Wisconsin Electric  Power Company  ("WEPCO") which  will be  renamed  "Wisconsin
Energy  Company." Wisconsin Energy Company will  include the operations of WEC's
other present  utility  subsidiary,  Wisconsin Natural  Gas  Company,  which  is
anticipated  to be merged into WEPCO by  January 1, 1996, as previously planned.
It is  anticipated  that, following  the  Transaction, the  Company's  Wisconsin
utility  subsidiary, NSP-Wisconsin, will be merged into Wisconsin Energy Company
and that NRG and  the Company's other subsidiaries  will become subsidiaries  of
Primergy.

                                       3
<PAGE>
    As  noted above, pursuant to the  Transaction the Company will reincorporate
in Wisconsin for regulatory reasons.  This reincorporation will be  accomplished
by  the merger  of the Company  into New NSP,  with New NSP  being the surviving
corporation and succeeding to the business of the Company as an operating public
utility. Following such merger, WEC  Sub will be merged  with and into New  NSP,
with  New  NSP being  the  surviving corporation  and  becoming a  subsidiary of
Primergy. Both New NSP and  WEC Sub were created  to effect the Transaction  and
will  not have any  significant operations, assets or  liabilities prior to such
mergers.

    The Transaction  is  subject  to customary  closing  conditions,  including,
without  limitation, the receipt of all necessary governmental approvals and the
making of all necessary governmental filings, all as more fully described in the
Form 10-Q.

    A preliminary estimate  indicates that  the Transaction will  result in  net
savings  of approximately $2.0 billion in costs over 10 years. It is anticipated
that the  synergies  created by  the  Transaction  will allow  the  Company  and
Wisconsin  Energy Company  to implement  a modest  reduction in  electric retail
rates followed by a rate freeze  for electric retail customers through the  year
2000.  Both the Company and WEC recognize that the divestiture of their existing
gas operations and certain non-utility operations is a possibility under the new
registered holding company structure, but will seek approval from the Commission
to  maintain  such  businesses.  If  divestiture  is  ultimately  required,  the
Commission  has  historically allowed  companies  sufficient time  to accomplish
divestitures in a manner that protects shareholder value.

    Following the  completion of  the  Transaction, the  Offered Bonds  and  the
Company's other outstanding first mortgage bonds will be obligations of New NSP,
as a subsidiary of Primergy, and will continue to be secured by the Indenture as
described  in  this Prospectus.  However,  as described  above,  New NSP  is not
expected to retain any of the Company's subsidiaries and the Offered Bonds  will
not  be an obligation of  Primergy or any other  subsidiary of Primergy. For the
twelve months ended  June 30, 1995  and the  year ended December  31, 1994,  the
Company's subsidiaries constituted 33% and 29% of NSP's consolidated net income,
respectively,  and represented 22% of NSP's consolidated assets and 17% of NSP's
consolidated liabilities including  long-term debt  at June 30,  1995. The  Form
10-Q filed with the Commission and incorporated by reference in this Prospectus,
includes   pro  forma  financial   information  for  the   Company  without  its
subsidiaries.

                                USE OF PROCEEDS

    The proceeds from the  sale of the  New Bonds will be  added to the  general
funds  of the Company and used for general corporate purposes, which may include
the purchase or redemption of one  or more series of outstanding first  mortgage
bonds  and  the  repayment  of  outstanding  short-term  borrowings  incurred in
connection with NSP's continuing construction program. Short-term borrowings  of
the  Company  aggregated  $169  million  as of  August  31,  1995.  The specific
allocation of the proceeds of a particular  series of the Offered Bonds will  be
described in the Prospectus Supplement.

deferred  income taxes and investment tax  credits and less undistributed equity
in earnings  of unconsolidated  investees;  and (ii)  fixed charges  consist  of
interest  on long-term debt,  other interest charges,  the interest component on
leases and amortization of debt discount, premium and expense.

    The New NSP unaudited pro forma ratios of earnings to fixed charges for each
of the years in the  three-year period ended December  31, 1994, and the  twelve
months ended June 30, 1995, give effect to the Transaction as if it had occurred
at  January 1, 1992.  See the Notes  to Unaudited Pro  Forma Condensed Financial
Statements of New NSP in the Form 10-Q for a description of the assumptions used
to prepare the unaudited pro forma ratios of earnings to fixed charges.

    Assuming that  variable  interest  rate debt  continues  at  interest  rates
applicable  on June 30, 1995, the  annual interest requirement on long-term debt
of NSP outstanding at June 30, 1995, was $108,336,000.

                            DESCRIPTION OF NEW BONDS

    Each series of New Bonds is to be an initial issue of a new series of  first
mortgage  bonds (the "Bonds") issued under the Trust Indenture dated February 1,
1937 (the "1937 Indenture") as supplemented by 44 supplemental trust  indentures
(collectively, the "Supplemental Indentures"), a Supplemental and Restated Trust
Indenture  dated May 1,  1988 (the "Restated Indenture")  and a new supplemental
trust indenture for such series of New Bonds (the "New Supplemental Indenture"),
all from  the  Company  to  Harris  Trust and  Savings  Bank,  as  trustee  (the
"Trustee").  The 1937 Indenture, as supplemented by the Supplemental Indentures,
the Restated Indenture and the New Supplemental Indenture herein are referred to
collectively as  the "Indenture."  Excluding the  New Bonds,  there will  be  14
series  of Bonds in an aggregate  principal amount of $1,094,800,000 outstanding
under the Indenture. Copies of the 1937 Indenture, the Supplemental  Indentures,
the  Restated Indenture and the form of the New Supplemental Indenture are filed
as Exhibits 4.01A  to 4.01UU to  the Registration Statement  and the  statements
herein made (being for the most part succinct summaries of certain provisions of
the Indenture) are subject to the detailed provisions of the 1937 Indenture, the
Supplemental  Indentures,  the  Restated  Indenture  and  the  New  Supplemental
Indenture which are incorporated herein by reference.

    The Restated  Indenture  amends and  restates  the 1937  Indenture  and  the
Supplemental  Indentures. The Restated  Indenture will not  become effective and
operative until all Bonds of each series issued under the Indenture prior to May
1, 1988 shall have been retired  through payment or redemption (including  those
Bonds  "deemed to be  paid" within the meaning  of that term  as used in Article
XVII of the 1937 Indenture) or (except as described below) until the holders  of
the  requisite  principal  amount of  such  Bonds  shall have  consented  to the
amendments contained in the Restated  Indenture (herein, the "Effective  Date").
Holders  of the New Bonds and of each series of Bonds issued under the Indenture
after May 1,  1988 likewise will  be bound  by the amendments  contained in  the
Restated  Indenture when they become effective  and operative. If the consent of
the holders of Bonds of each series issued prior to May 1, 1988 is not  obtained
or  such Bonds are  not retired prior  to their maturity,  the Company presently
expects the Restated Indenture to become  effective no earlier than December  1,
2006.

    The  following summary  of the provisions  of the  Indenture includes, where
applicable, a discussion of the amendments contained in the Restated  Indenture.
References  are  made  to  specific  Article and  Section  numbers  of  the 1937
Indenture, the  Supplemental  Indentures, the  Restated  Indenture and  the  New
Supplemental Indenture. Unless the context indicates otherwise, words or phrases
defined  in  the  1937  Indenture,  the  Supplemental  Indentures,  the Restated
Indenture or the New  Supplemental Indenture are capitalized  and used with  the
same meanings herein.

TERMS OF NEW BONDS

    The  New Bonds will be  issued as fully registered  bonds without coupons in
denominations of multiples of $1,000. New Bonds may be issued in temporary  form
if,  for any reason,  the Company is  unable to deliver  New Bonds in definitive
form. Principal and interest are to  be payable in Chicago, Illinois, at  Harris
Trust  and Savings Bank or in New York,  New York at Harris Trust Company of New
York.

                                       5
<PAGE>
New Bonds will be interchangeable  in the manner provided  in Article II of  the
New  Supplemental  Indenture. The  New Bonds  may be  issued in  book-entry form
through the  facilities  of a  depository.  The description  of  any  book-entry
arrangements will be contained in the Prospectus Supplement.

    No  charge will be made  by the Company for any  exchange or transfer of New
Bonds, other than for any taxes or other governmental charges.

    Reference is  made to  the Prospectus  Supplement that  will accompany  this
Prospectus  for the  following terms and  other information with  respect to the
Offered Bonds:  (1)  the designation  and  aggregate principal  amount  of  such
Offered  Bonds; (2) the date  or dates on which  such Offered Bonds will mature;
(3) the rate or rates per annum (or method of calculation) at which such Offered
Bonds will bear interest and the date from which such interest shall accrue; (4)
the dates on  which such  interest will  be payable;  (5) the  record dates  for
payments  of interest;  and (6)  any optional  or mandatory  redemption terms or
other specific  terms  applicable to  the  Offered  Bonds. The  holders  of  the
outstanding  Bonds do not, and  the holders of the New  Bonds will not, have the
right to  tender such  Bonds to  the  Company for  repurchase upon  the  Company
becoming  involved in a  highly leveraged or change  in control transaction. The
Indenture does not have any provision that is designed specifically in  response
to  highly  leveraged or  change in  control transactions.  However, bondholders
would have the security afforded by the first mortgage lien on substantially all
the Company's  property as  described  under the  subcaption "Security  for  New
Bonds"  below. In addition, any change in control transaction and any incurrence
of additional indebtedness (as first mortgage bonds or otherwise) by the Company
in such  a  transaction  would  require approval  of  state  utility  regulatory
authorities and, possibly, of federal utility regulatory authorities. Management
believes  that such  approvals would be  unlikely in any  transaction that would
result in the Company, or a successor to the Company, having a highly  leveraged
capital structure. See "PROPOSED MERGER."

SECURITY FOR NEW BONDS

    In the opinion of counsel for the Company, the New Bonds when issued will be
secured  equally and  ratably, except  as to  sinking fund  provisions, with all
other outstanding Bonds by a valid and direct first mortgage lien on all of  the
real  and fixed properties, leasehold rights,  franchises and permits then owned
by the Company subject only  (a) to Permitted Liens and  (b) as to parts of  the
Company's  property, to certain easements,  conditions, restrictions, leases and
similar encumbrances which do not affect  the Company's use of such property  in
the  usual course of its business, to  certain minor defects in titles which are
not material and to defects in titles to certain properties not essential to the
Company's business. The Indenture contains provisions for subjecting to the lien
thereof all  property,  rights and  franchises  (except as  otherwise  expressly
provided)  acquired by the  Company after the  date of the  1937 Indenture. Such
provisions might not be effective as to property acquired, within 90 days  prior
and  subsequent to the filing of a case,  with respect to the Company, under the
United States Bankruptcy Code. The opinion  of counsel does not cover titles  to
easements  for  water flowage  purposes or  rights-of-way  for electric  and gas
transmission and  distribution  facilities,  steam mains  and  telephone  lines.
However,  the Company has the power of eminent  domain in the states in which it
operates.

    The Indenture provides that no prior liens, other than Permitted Liens,  may
be created or permitted to exist upon the mortgaged and pledged property whether
now  owned  or  hereafter acquired.  (Section  4  of Article  VIII  of  the 1937
Indenture.) Following the retirement of the Bonds of each series issued prior to
May 1, 1988, the Restated Indenture will amend the foregoing provisions to allow
Permitted  Encumbrances  on  the  mortgaged  and  pledged  property.   Permitted
Encumbrances  include Permitted Liens and (a)  rights of Persons who are parties
to agreements with the  Company relating to property  owned or used jointly  (in
common)  by the Company with such Persons,  provided (i) that such rights do not
materially impair the use of such jointly  owned or used property in the  normal
operation  of the Company's  business and do not  materially affect the security
afforded by the Indenture  and (ii) that such  rights are not inconsistent  with
the remedies of the Trustee upon a Completed Default; (b) (i) leases existing at
the  Effective Date  of the Restated  Indenture affecting property  owned by the
Company on  the  Effective Date;  (ii)  leases which  do  not interfere  in  any
material respect with the use of the related

                                       6
<PAGE>
property  for the purpose for which it is held by the Company and which will not
have a material  adverse impact  on the security  afforded by  the Indenture  or
(iii)  other leases  relating to not  more than 5%  of the sum  of the Company's
Depreciable Property and Land; and (c) any mortgage, lien, charge or encumbrance
prior or equal to the Lien of the Indenture, other than a Prepaid Lien, existing
at the date any property is acquired  by the Company, provided that at the  date
of  acquisition of such property: (i) no Default has occurred and is continuing;
(ii) the principal amount of indebtedness outstanding under and secured by  such
mortgage,  lien, charge or encumbrance shall not exceed 66 2/3% of the lesser of
the Cost  or  Fair Value  of  the property  so  acquired; and  (iii)  each  such
mortgage,  lien,  charge or  encumbrance shall  apply only  to the  property and
improvements originally subject thereto and that  the Company shall cause to  be
closed  all mortgages or other liens existing  at the time of acquisition of any
property thereafter  acquired  by the  Company  and will  permit  no  additional
indebtedness  to be issued  thereunder or secured thereby.  (Section 1.03 of the
Restated Indenture.)

    Following the retirement of the Bonds of each series issued prior to May  1,
1988,  the holders of 66  2/3% of the principal  amount of Bonds Outstanding may
(a) consent to the creation or existence of  a Prior Lien with respect to up  to
50%  of the  sum of  the Company's Depreciable  Property and  Land, after giving
effect to  such Prior  Lien or  (b) terminate  the Lien  of the  Indenture  with
respect  to up to 50% of the sum of the Company's Depreciable Property and Land.
(Section 18.02(e) of the Restated Indenture.)

    The Indenture is not a lien on  the properties of NSP-Wisconsin, nor is  the
stock of NSP-Wisconsin, NRG, Viking or any other subsidiary owned by the Company
pledged thereunder.

SINKING FUND PROVISIONS

    The  sinking fund redemption provision,  if any, for each  series of the New
Bonds will  be set  forth in  the related  Prospectus Supplement.  As an  annual
sinking  fund, the Company covenants to pay  to the Trustee annually, on October
1, an amount sufficient to redeem, for sinking fund purposes, 1% of the  highest
amount, at any time outstanding, of each outstanding series of Bonds, other than
Bonds  of the Series due October 1, 1997, Bonds of the Series due April 1, 2003,
Bonds of the Series due  December 1, 2000, Bonds of  the Series due December  1,
2005,  Bonds of the Series due February 1, 1999, Bonds of the Series due October
1, 2001, Bonds of the Series due  July 1, 2025 and other than Pollution  Control
Series  C, J, K, L and Resource Recovery  Series I. Sinking fund payments may be
offset by (a) application of  net Permanent Additions of  a Cost or Fair  Value,
whichever  is  less,  equal to  150%  of  the principal  amount  of  Bonds which
otherwise would be required to be retired by the sinking fund or (b)  retirement
or  delivery to the Trustee of Bonds of the series for which the sinking fund is
applicable. The Trustee is required to apply sinking fund money to the  purchase
or  redemption  of Bonds  of  the series  for  which such  money  is applicable.
(Article III of  each Supplemental Indenture  except those dated  June 1,  1942,
February 1, 1944, October 1, 1945, July 1, 1948, August 1, 1949, August 1, 1957,
October  1, 1992, April 1, 1993, December  1, 1993, February 1, 1994, October 1,
1994, June 1, 1995 and  those relating to each  Pollution Control Series and  to
Resource Recovery Series I.)

    Certain  of  the  Bonds of  Resource  Recovery  Series I  are  subject  to a
mandatory sinking fund applicable  to each respective  series. (Section 3.02  of
the Supplemental Indenture dated December 1, 1984.)

MAINTENANCE PROVISIONS

    As  a Maintenance Fund  for the Bonds,  the Company covenants  to pay to the
Trustee annually on  May 1  an amount  equal to  15% of  the Consolidated  Gross
Operating  Revenues  of  the  Company for  the  preceding  calendar  year, after
deducting from such  revenues: (a)  cost of  electricity and  gas purchased  for
resale,  (b) rentals  paid for utility  property, less credits  at the Company's
option for  (i)  maintenance,  (ii) property  retirements  offset  by  Permanent
Additions,  (iii) retirements of Bonds and (iv) Cost or Fair Value, whichever is
less, of Permanent Additions  after deducting property retirements.  Withdrawals
from  the Maintenance Fund may be made on  the basis of retirements of Bonds and
net Permanent Additions, but cash in excess of $100,000 remaining on deposit  in
the  Maintenance Fund for more than three years must be used for the purchase or
redemption  of  Bonds.  Any   such  redemption  would   be  at  the   applicable

                                       7
<PAGE>
regular  redemption  price  of the  Bonds  to  be redeemed  and  subject  to any
restrictions on the redemption of such Bonds. (Article IX of the 1937 Indenture;
Article IV of the Supplemental Indenture dated June 1, 1952.)

    The Restated Indenture will amend the foregoing provisions of the  Indenture
by  replacing the current Maintenance Fund  deposit formula with the requirement
that the Company pay to the Trustee annually  on May 1 an amount equal to  2.50%
of  its Completed Depreciable Property  as of the end  of the preceding calendar
year, after deducting credits at the  Company's option for (a) maintenance,  (b)
property retirements offset by Permanent Additions, (c) retirements of Bonds and
(d)  Amounts of Established  Permanent Additions. (Section  9.01 of the Restated
Indenture.) The  Restated Indenture  further provides  that to  the extent  that
Maintenance  Fund credits exceed 2.50% of Completed Depreciable Property for any
year after 1987,  such excess  credits may  be applied  in future  years (a)  to
offset  any  Maintenance  Fund  deficiency  or (b)  to  increase  the  Amount of
Established Permanent Additions available for use under the Indenture.  (Section
9.05  of the Restated Indenture.) In addition, the Restated Indenture eliminates
the requirement that  cash in  excess of $100,000  remaining on  deposit in  the
Maintenance  Fund  for  more  than  three years  be  used  for  the  purchase or
redemption of Bonds.

    The Company has covenanted  to maintain its  properties in adequate  repair,
working  order and condition. (Section 6 of  Article VIII of the 1937 Indenture;
Section 8.06 of the Restated Indenture.)

ISSUANCE OF ADDITIONAL BONDS

    The maximum principal amount of Bonds that may be issued under the Indenture
is not limited, except as described below. Additional Bonds may be issued on the
basis of (a)  60% of the  Cost or Fair  Value, whichever is  less, of  Permanent
Additions  after deducting  retirements (Article V  of the  1937 Indenture; also
Sections 1 and 3 of Article III of the Supplemental Indenture dated February  1,
1944); (b) retired Bonds, which have not been otherwise used under the Indenture
(Article  VI of the 1937 Indenture); and (c)  deposit of an equal amount of cash
with the Trustee, which cash  may be withdrawn on  the same basis as  additional
Bonds  may be issued under  clauses (a) and (b) above.  (Article VII of the 1937
Indenture; Section 2 of Article III of the Supplemental Indenture dated February
1, 1944; and Article IV of the  Supplemental Indenture dated June 1, 1952.)  The
Restated  Indenture  will amend  the foregoing  provisions  of the  Indenture by
increasing the percentage in clause (a) above from 60% to 66 2/3%. (Section 5.03
of the Restated Indenture.)

    The New Bonds will be  issued under clause (a)  and/or (b) above. At  August
31,  1995, the amount of  net Permanent Additions available  for the issuance of
Bonds exceeded  $4.2  billion, of  which  $500 million  could  be used  for  the
authentication  of $300 million principal amount of  the New Bonds. As of August
31, 1995, $327 million of retired Bonds were available for the authentication of
up to $327 million of New Bonds.

    No additional Bonds may  be issued on  the basis of  clause (a), clause  (b)
under  specified conditions,  or clause (c),  unless the  Earnings Applicable to
Bond Interest for a specified twelve-month period are equal to twice the  annual
interest requirements on the Bonds, including those about to be issued. (Section
4  of Article V, Section  2 of Article VI,  and Section 1 of  Article VII of the
1937 Indenture.)

    Permanent Additions include:  the Company's electric  and steam  generating,
transmission   and  distribution  properties;  the  Company's  gas  storage  and
distribution  properties;  construction  work-in-progress;  and  fractional  and
undivided property interests of the Company. (Section 4 of Article I of the 1937
Indenture;   Section  1.03  of  the  Restated  Indenture.)  Under  the  Restated
Indenture, Permanent Additions  also will  include property  used for  providing
telephone  or other communication services and engineering, financial, economic,
environmental, geological  and  legal  or  other  studies,  surveys  or  reports
associated  with the  acquisition or  construction of  any Depreciable Property.
(Section 1.03 of the Restated Indenture.)

    Assuming that the  interest cost on  variable rate Bonds  is at the  maximum
allowable rate, Earnings Applicable to Bond Interest for the twelve months ended
August  31, 1995,  would be  4.9 times the  annual interest  requirements on the
Bonds including  the  New Bonds  at  an  assumed 8%  interest  rate.  Additional

                                       8
<PAGE>
Bonds  may vary from the Offered Bonds as to maturity, interest rate, redemption
prices, and sinking fund, and in certain other respects. (Article II of the 1937
Indenture and Article II of the Restated Indenture.) The Restated Indenture will
amend the Indenture by requiring that Earnings Applicable to Bond Interest for a
specified twelve-month period be equal to twice the annual interest requirements
on the Bonds, including those about to be issued, and any obligations secured by
Prior Liens and  any indebtedness secured  by Permitted Encumbrances.  (Sections
1.03  and 5.04  of the  Restated Indenture.)  Under the  Restated Indenture, the
calculation of Earnings Applicable to Bond Interest will include all non-utility
revenues of the Company. (Section 1.03 of the Restated Indenture.)

PROVISION LIMITING DIVIDENDS ON COMMON STOCK

    The  Company  has  covenanted  that  the  sum  of  (i)  all  dividends   and
distributions on the common stock of the Company after September 30, 1954 (other
than  in common  stock), and  (ii) the cost  of all  shares of  its common stock
acquired by  it after  that date  shall not  exceed the  sum of  (a) the  earned
surplus  of the Company and its Qualified Subsidiary Companies, consolidated, at
September 30, 1954, and (b)  an amount equal to  the consolidated net income  of
the  Company and its Qualified Subsidiary  Companies, earned after September 30,
1954, after  making provision  for all  dividends accruing  after that  date  on
preferred  stock of the  Company and after taking  into consideration all proper
charges and credits  to earned surplus  made after that  date. In computing  net
income  for the purpose of  this covenant, there will  be deducted an amount, if
any, by  which  15%  of  the  Consolidated  Gross  Operating  Revenues  of  such
companies,  after  certain  deductions,  exceeds the  aggregate  of  the amounts
expended  for   maintenance  and   appropriated  for   reserves  for   renewals,
replacements,  retirements,  depreciation  or  depletion.  (Article  IV  of  the
Supplemental Indenture dated October 1, 1954.) As of 1957, the Company no longer
had any  Qualified Subsidiary  Companies. This  provision has  not impaired  the
Company's  ability to pay dividends in the past  and is not expected to do so in
the future.

    The Restated Indenture will replace the dividend restriction described above
with the requirement that (a) the sum of: (i) all dividends and distributions on
the Company's common stock  after the Effective Date  of the Restated  Indenture
(other  than  in  common  stock) and  (ii)  the  amount, if  any,  by  which the
Considerations given by the Company for the purchase or other acquisition of its
common stock after the Effective Date exceeds the Considerations received by  it
after the Effective Date from the sale of common stock, shall not exceed (b) the
sum  of (i) the retained earnings of the Company at the Effective Date, and (ii)
an amount equal  to the net  income of  the Company earned  after the  Effective
Date,  after deducting  all dividends accruing  after the Effective  Date on all
classes and  series of  preferred stock  of the  Company and  after taking  into
consideration  all proper charges  and credits to earned  surplus made after the
Effective Date.  In  computing  net  income for  the  purpose  of  this  amended
covenant,  there will be deducted  the amount, if any,  by which, after the date
commencing 365 days  prior to  the Effective  Date, the  actual expenditures  or
charges  for  ordinary repairs  and maintenance  and  the charges  for reserves,
renewals, replacements, retirements,  depreciation and depletion  are less  than
2.50%  of the  Company's Completed  Depreciable Property.  (Section 8.07  of the
Restated Indenture.)

RELEASE PROVISIONS

    The Indenture contains provisions  permitting the release  from its lien  of
any  property  upon depositing  or pledging  cash or  certain other  property of
comparable Fair Value. The  Indenture also contains provisions  for the sale  or
other  disposal  of  securities  not  pledged  under  the  Indenture, contracts,
accounts, motor cars, and certain equipment and supplies; for the  cancellation,
change  or  alteration  of  leases, rights-of-way  and  easements;  and  for the
surrender and modification of any  franchise or governmental consent subject  to
certain restrictions; in each case without any release or consent by the Trustee
or  accountability  thereto  for  any  consideration  received  by  the Company.
(Article XI of the 1937 Indenture and Article XI of the Restated Indenture.)

    Following the retirement of the Bonds of each series issued prior to May  1,
1988,  (a) the Company may sell or otherwise dispose of, free of the Lien of the
Indenture, all  motor vehicles,  vessels and  marine equipment,  railroad  cars,
engines  and  related  equipment,  airplanes,  office  furniture  and  leasehold
interests in property owned by third parties and (b) the Company may enter  into
leases with respect to

                                       9
<PAGE>
the  property subject to the Lien of the Indenture which do not interfere in any
material respect with the use of such  property for the purpose for which it  is
held  by the Company and will not have a material adverse impact on the security
afforded by the Indenture. (Section 11.02(b) of the Restated Indenture.)

    Following the retirement of the Bonds of each series issued prior to May  1,
1988, any of the mortgaged and pledged property may be released from the Lien of
the  Indenture if, after such release, the Fair Value of the remaining mortgaged
and pledged property  equals or exceeds  a sum  equal to 150%  of the  aggregate
principal  amount  of  Bonds  Outstanding.  (Section  11.03(k)  of  the Restated
Indenture.) When effective and upon  satisfaction of the requirements set  forth
in  the  Indenture,  this provision  would  permit  the Company  to  spin-off or
otherwise dispose  of a  substantial amount  of  assets or  a line  of  business
without depositing cash or property with the Trustee or obtaining the consent of
the bondholders.

MODIFICATION OF THE INDENTURE

    With  the consent  of the  Company, the provisions  of the  Indenture may be
changed by the affirmative vote of the holders of 80% in principal amount of the
Bonds Outstanding except that,  among other things, the  maturity of a Bond  may
not  be  extended,  the interest  rate  reduced,  nor the  terms  of  payment of
principal or interest changed without the consent of the holder of each Bond  so
affected. (Article XVIII of the 1937 Indenture.)

    The   Supplemental  Indenture  dated  May  1,  1985  amended  the  foregoing
provisions of the  Indenture by reducing  the 80% requirement  to 66 2/3%.  This
amendment will not become effective and operative until all Bonds of each series
issued  prior to May  1, 1985 shall have  been retired or  until all the holders
thereof shall have consented to such amendment. Holders of the New Bonds and  of
each  subsequent series issued under the Indenture will likewise be bound by the
amendment  when  it  becomes  effective  and  operative.  (Article  VI  of   the
Supplemental  Indenture  dated May  1, 1985  and Section  18.02 of  the Restated
Indenture.)

CONCERNING THE TRUSTEE

    In case of a Completed Default either  the Trustee or the holders of 25%  in
principal amount of (i) the Bonds Outstanding or (ii) the Bonds affected by such
default,  may declare  the Bonds  due and  payable subject  to the  right of the
holders of a majority  of the Bonds  then Outstanding to  rescind or annul  such
action.  Further, it is obligatory upon the Trustee to take the actions provided
in the Indenture to enforce payment of  the Bonds and the Lien of the  Indenture
upon  being requested to do so by the  holders of a majority in principal amount
of the Bonds.  However, the holders  of a  majority in principal  amount of  the
Bonds may direct the taking of any such action or the refraining therefrom as is
not  contrary  to law  or the  Indenture.  As a  condition precedent  to certain
actions, the Trustee may require adequate indemnity against the costs,  expenses
and  liabilities to be  incurred therein or  thereby. (Article XIII  of the 1937
Indenture; Section 6 of Article VI  of Supplemental Indenture dated February  1,
1944;  Section 4.03 of Supplemental Indenture  dated October 1, 1945 and Article
XIII of the Restated Indenture.)

                              PLAN OF DISTRIBUTION

    The  Company  may sell  the  New Bonds  (i)  to or  through  underwriters or
dealers; (ii) directly to one or  more purchasers; or (iii) through agents.  The
Prospectus Supplement with respect to each series of

                                       11
<PAGE>
Offered  Bonds will set forth  the terms of the  offering of such Offered Bonds,
including the name  or names  of any underwriters,  the purchase  price of  such
Offered  Bonds and the proceeds to the  Company from such sale, any underwriting
discounts and other items  constituting underwriters' compensation, any  initial
public offering price, any discounts or concessions allowed or reallowed or paid
to  dealers and  any securities  exchanges on  which such  Offered Bonds  may be
listed. Any initial offering price and any discounts, concessions or commissions
allowed or reallowed or paid to dealers may be changed from time to time.

    If underwriters are used in the sale, the Offered Bonds will be acquired  by
the  underwriters for their own  account and may be resold  from time to time in
one or more transactions, including  negotiated transactions, at a fixed  public
offering  price or at varying prices determined at the time of sale. The Offered
Bonds may  be  offered to  the  public either  through  underwriting  syndicates
represented  by one or more managing underwriters  or directly by one or more of
such firms. The specific managing underwriter  or underwriters, if any, will  be
set  forth in the  Prospectus Supplement relating to  the Offered Bonds together
with the members  of the underwriting  syndicate, if any.  Unless otherwise  set
forth  in  the Prospectus  Supplement, the  obligations  of the  underwriters to
purchase the Offered Bonds offered thereby will be subject to certain conditions
precedent and the underwriters  will be obligated to  purchase all such  Offered
Bonds if any are purchased.

    Offered  Bonds  may  be  sold  directly by  the  Company  or  through agents
designated by the Company from time to time. The Prospectus Supplement will  set
forth  the name of any agent involved in  the offer or sale of the Offered Bonds
in respect of which the Prospectus  Supplement is delivered and any  commissions
payable by the Company to such agent.

    Any underwriters, dealers or agents participating in the distribution of the
Offered  Bonds may be deemed to be underwriters and any discounts or commissions
received by them on the sale or resale of the Offered Bonds may be deemed to  be
underwriting  discounts and commissions under the Securities Act of 1933. Agents
and underwriters  may  be  entitled,  under agreements  entered  into  with  the
Company,  to indemnification by  the Company against  certain civil liabilities,
including liabilities under the Securities Act of 1933, or to contributions with
respect to payments which the agents or underwriters may be required to make  in
respect  thereof. Agents  and underwriters  may engage  in transactions  with or
perform services for the Company in the ordinary course of business.

ITEM 17.  UNDERTAKINGS.

    The undersigned registrant hereby undertakes:

        (1) To file, during any period in which offers or sales are being  made,
    a  post-effective amendment to  this registration statement:  (i) to include
    any prospectus required by section 10(a)(3)  of the Securities Act of  1933;
    (ii)  to reflect  in the  prospectus any facts  or events  arising after the
    effective  date  of   the  registration  statement   (or  the  most   recent
    post-effective  amendment thereof) which, individually  or in the aggregate,
    represent  a  fundamental  change  in  the  information  set  forth  in  the
    registration  statement.  Notwithstanding  the  foregoing,  any  increase or
    decrease in  volume of  securities offered  (if the  total dollar  value  of
    securities  offered  would not  exceed that  which  was registered)  and any
    deviation from the low or high  end of the estimated maximum offering  range
    may  be  reflected  in the  form  of  prospectus filed  with  the Commission
    pursuant to Rule 424(b) if, in

                                      II-4
<PAGE>
    the aggregate, the changes  in volume and price  represented no more than  a
    20%  change  in  the  maximum  aggregate offering  price  set  forth  in the
    "Calculation of  Registration  Fee"  table  in  the  effective  registration
    statement; and (iii) to include any material information with respect to the
    plan  of distribution not previously disclosed in the registration statement
    or any material change  to such information  in the registration  statement;
    provided,  however, that  clauses (i)  and (ii)  above do  not apply  if the
    registration statement  is on  Form  S-3 or  Form  S-8 and  the  information
    required  to be included  in a post-effective amendment  by those clauses is
    contained in periodic reports filed by the registrant pursuant to section 13
    or  section  15(d)  of  the  Securities  Exchange  Act  of  1934  that   are
    incorporated by reference in the registration statement.

        (2)  That,  for  the  purpose of  determining  any  liability  under the
    Securities Act of 1933, each  such post-effective amendment shall be  deemed
    to  be  a  new registration  statement  relating to  the  securities offered
    therein, and the offering of such securities at that time shall be deemed to
    be the initial bona fide offering thereof.

        (3) To remove from registration  by means of a post-effective  amendment
    any   of  the  securities  being  registered  which  remain  unsold  at  the
    termination of the offering.

    The  undersigned  registrant  hereby   undertakes  that,  for  purposes   of
determining  any liability under the Securities Act  of 1933, each filing of the
registrant's annual report  pursuant to section  13(a) or section  15(d) of  the
Securities  Exchange  Act  of 1934  (and  where  applicable, each  filing  of an
employee  benefit  plan's  annual  report  pursuant  to  section  15(d)  of  the
Securities  Exchange  Act of  1934)  that is  incorporated  by reference  in the
registration statement  shall  be deemed  to  be a  new  registration  statement
relating  to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

    Insofar as indemnification for liabilities arising under the Securities  Act
of  1933 may be permitted to directors,  officers and controlling persons of the
registrant pursuant  to the  foregoing provisions  described under  Item 15,  or
otherwise, the registrant has been advised that in the opinion of the Securities
and  Exchange  Commission  such  indemnification  is  against  public  policy as
expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the
event that a claim for indemnification against such liabilities (other than  the
payment by the registrant of expenses incurred or paid by a director, officer or
controlling  person of the  registrant in the successful  defense of any action,
suit or proceeding) is asserted by such director, officer or controlling  person
in  connection with the securities being registered, the registrant will, unless
in the  opinion  of its  counsel  the matter  has  been settled  by  controlling
precedent,  submit to a  court of appropriate  jurisdiction the question whether
such indemnification  by  it  is  against public  policy  as  expressed  in  the
Securities  Act of 1933 and  will be governed by  the final adjudication of such
issue.

and warrants to, and agrees with, each Underwriter that:

        (a) The Company  meets the requirements  for use of  Form S-3 under  the
    Securities  Act  of 1933,  as amended  (the  "Act") and  has filed  with the
    Securities  and  Exchange  Commission  (the  "Commission")  a   registration

    Rule   434  under  the  Act.  Copies  of  such  registration  statement  and

    Statement or the  Prospectus shall  be deemed to  refer to  and include  the
    documents  incorporated by reference therein pursuant to Item 12 of Form S-3

    "Exchange  Act") on or before the date of this Agreement and, if the Company
    files any  document pursuant  to the  Exchange Act  after the  date of  this
    Agreement  and prior to the termination of  the offering of the Bonds by the
    Underwriters, which documents  are deemed  to be  incorporated by  reference
    into  the  Prospectus,  the  term  "Prospectus"  shall  refer  also  to said
    prospectus as supplemented by the documents so filed from and after the time

    to  the Registration  Statement or  any documents  incorporated by reference
    therein by the Act, the Exchange Act or the rules and regulations thereunder

    Registration   Statement  has  been   issued  by  the   Commission  and  the

    material  respects with the requirements of the Act, the Trust Indenture Act
    of 1939, as amended (the "Trust Indenture Act") and the respective rules and
    regulations of  the Commission  thereunder and  did not  contain any  untrue
    statement of a material fact or omit any material fact required to be stated
    therein or necessary in order to make the statements therein not misleading;
    and,  at the time the Prospectus Supplement is filed with the Commission and
    at the Closing Date (as hereinafter defined), the Prospectus will comply  in
    all  material respects  with the  Act and the  rules and  regulations of the
    Commission thereunder  and  will  not  contain any  untrue  statement  of  a
    material  fact or  omit to  state any  material fact  required to  be stated
    therein or necessary to make the statements therein not misleading; PROVIDED

    of  the  Registration  Statement  which shall  constitute  the  Statement of
    Eligibility (Form T-1) under the Trust  Indenture Act of the Trustee or  (B)
    the  information contained in or omitted  from the Registration Statement or
    the Prospectus in reliance upon and in conformity with information furnished
    in writing to the  Company by or  on behalf of  any Underwriter through  the
    Representatives  specifically  for  use  in  the  Registration  Statement or
    Prospectus.

        (c) The documents incorporated by reference in the Prospectus, when they
    were filed with the  Commission, conformed in all  material respects to  the

    thereunder; and none of  such documents include or  will include any  untrue
    statement of a material fact or omit or will omit to state any material fact
    required to be stated therein or necessary to make the statements therein in
    the light of the circumstances under which they were made not misleading.

    subsidiaries filed  as  a  part  of or  incorporated  by  reference  in  the
    Registration  Statement or Prospectus fairly  present the financial position
    of the Company and its consolidated  subsidiaries as of the dates  indicated
    and  the results of  their operations and changes  in financial position for
    the periods specified, and have  been prepared in conformity with  generally
    accepted  accounting principles applied on a consistent basis throughout the
    periods involved,  except as  disclosed in  the Prospectus  Supplement.  The
    unaudited  pro forma financial information  incorporated by reference in the
    Registration Statement and the Prospectus complies in all material  respects
    with  the applicable accounting requirements of Rule 11-02 of Regulation S-X
    and the pro forma adjustments have  been properly applied to the  historical
    amounts in the compilation of such information.

    corporation in good standing under the  laws of the State of Minnesota  with

    of each such subsidiary has been  duly authorized and validly issued and  is
    fully paid and non-assessable; and the capital stock of each such subsidiary
    owned  by the Company,  directly or through subsidiaries,  is owned free and
    clear of any pledge, lien, encumbrance, claim or equity.

        (h) Neither the Company nor any of its subsidiaries has sustained  since
    the date of the latest audited financial statements included or incorporated
    by  reference in the  Prospectus any material loss  or interference with its
    business from  fire, explosion,  flood  or other  calamity, whether  or  not
    covered  by insurance,  or from any  labor dispute or  court or governmental
    action, order or decree, otherwise than as set forth or contemplated in  the
    Prospectus   Supplement;  and,  since  the  respective  dates  as  of  which
    information is  given  in  the Registration  Statement  and  the  Prospectus
    Supplement, neither the Company nor any of its subsidiaries has incurred any
    liabilities  or  obligations,  direct  or contingent,  or  entered  into any
    transactions, not in the ordinary course of business, which are material  to
    the Company and its subsidiaries, and there has not been any material change
    in  the  capital  stock or  long-term  debt of  the  Company or  any  of its
    subsidiaries or any material adverse change, or any development involving  a
    prospective  material adverse change,  in or affecting  the general affairs,
    management,  financial  position,   stockholders'  equity   or  results   of
    operations  of the Company and its subsidiaries, otherwise than as set forth
    or contemplated in the Prospectus Supplement.

        (i) Neither  the  execution  and  delivery of  this  Agreement  and  the
    Indenture,  the issuance and delivery of  the Bonds, the consummation of the
    transactions herein contemplated, the fulfillment  of the terms hereof,  nor
    compliance  with the terms  and provisions of this  Agreement, the Bonds and
    the Indenture will conflict  with, or result  in the breach  of, any of  the
    terms,  provisions or conditions of  the Restated Articles of Incorporation,
    as amended, or  by-laws of  the Company, or  of any  contract, agreement  or
    instrument  to which the  Company is a party  or in which  the Company has a
    beneficial interest or by which the Company  is bound or of any order,  rule
    or  regulation applicable to the  Company of any court  or of any federal or
    state regulatory body  or administrative agency  or other governmental  body
    having jurisdiction over the Company or over its properties.

        (j)  The Bonds have been duly  authorized for issuance and sale pursuant
    to this Agreement and,  when executed and  authenticated in accordance  with
    the  Indenture and delivered and  paid for as provided  herein, will be duly
    issued and  will constitute  valid and  binding obligations  of the  Company
    enforceable in accordance with their terms, except as limited by bankruptcy,
    insolvency  and other laws  affecting enforcement of  creditors' rights, and
    will  be  entitled  to  the  benefits   of  the  Indenture  which  will   be
    substantially in the form heretofore delivered to you.

        (k)  The Indenture has  been duly and validly  authorized by the Company
    and,  when  duly  executed  and  delivered  by  the  Company,  assuming  due
    authorization,   execution  and  delivery  thereof   by  the  Trustee,  will
    constitute a  valid and  binding obligation  of the  Company enforceable  in
    accordance  with its terms, except as  enforcement thereof may be limited by
    bankruptcy, insolvency  or other  laws affecting  enforcement of  creditors'
    rights.

        (l)  The  Minnesota Public  Utilities  Commission has  issued  its order
    approving capital  structure  which order  authorizes  the issuance  of  the
    Bonds,  and  no  other approval  of  any  regulatory public  body,  state or
    federal, is,  or will  be  at the  Closing  Date (as  hereinafter  defined),
    necessary  in connection with the issuance and sale of the Bonds pursuant to
    this Agreement,  other  than approvals  that  may be  required  under  state
    securities laws.

       (m)  The Company has good and valid  title to all real and fixed property
    and leasehold rights described or  enumerated in the Indenture (except  such
    properties  as have been  released from the lien  thereof in accordance with
    the  terms  thereof),  subject  only  to  taxes  and  assessments  not   yet
    delinquent;  the  lien  of  the  Indenture; as  to  parts  of  the Company's
    property, certain easements, conditions,  restrictions, leases, and  similar
    encumbrances  which do not affect the Company's  use of such property in the
    usual course of its business, and certain minor defects in titles which  are
    not material, and defects

                                       3
<PAGE>
    in  titles to  certain properties which  are not essential  to the Company's
    business; and mechanics' lien claims being contested or not of record or for
    the satisfaction or discharge of which  adequate provision has been made  by
    the  Company pursuant to the Indenture;  and any real property and buildings
    held under lease by the  Company is held by  it under valid, subsisting  and
    enforceable  leases  with such  exceptions as  are not  material and  do not
    interfere with the use  made and proposed  to be made  of such property  and
    buildings by the Company.

        (n)  Other than as set forth or contemplated in the Prospectus as of the
    date hereof, there are no legal or governmental proceedings pending to which
    the Company or any of its subsidiaries  is a party or of which any  property
    of  the  Company  or  any  of its  subsidiaries  is  the  subject  which, if
    determined adversely  to  the Company  or  any of  its  subsidiaries,  would
    individually  or  in the  aggregate have  a material  adverse effect  on the
    consolidated  financial  position,  stockholders'   equity  or  results   of
    operations  of the  Company and  its subsidiaries; and,  to the  best of the
    Company's knowledge, no such proceedings  are threatened or contemplated  by
    governmental authorities or threatened by others.

        (o) The Company is not an "investment company" or an entity "controlled"
    by  an "investment company,  " as such  terms are defined  in the Investment
    Company Act of 1940, as amended.

        (p) Except as set  forth in the Prospectus  Supplement, the Company  and
    its  subsidiaries (A) are in compliance with any and all applicable federal,
    state and local  laws and regulations  relating to the  protection of  human
    health  and  safety, the  environment or  hazardous  or toxic  substances or
    wastes, pollutants or contaminants ("Environmental Laws"), (B) have received
    all permits, licenses or other  approvals required of them under  applicable
    Environmental  Laws  to  conduct  its respective  business  and  (C)  are in
    compliance with all terms  and conditions of any  such permits, licenses  or
    approvals,  except where such noncompliance with Environmental Laws, failure
    to receive  required permits,  licenses  or other  approvals or  failure  to
    comply  with the terms and conditions of such permits, licenses or approvals
    would not, singly or in the aggregate, have a material adverse effect on the
    Company and its subsidiaries, taken as a whole.

    2.  PURCHASE AND SALE.  Subject to the terms and conditions and in  reliance
upon  the representations and warranties herein set forth, the Company agrees to
sell to the Representatives and each other Underwriter, and the  Representatives
and  each other Underwriter  agree, severally and not  jointly, to purchase from
the Company,  at  the  purchase  price  set forth  in  Schedule  I  hereto,  the
respective  principal amounts of  the Bonds set  forth opposite their respective
names in Schedule II hereto.

    3.  DELIVERY AND PAYMENT.   Delivery of and payment  for the Bonds shall  be
made  at the place, date and time specified  in Schedule I hereto (or such other
place, date and time not later than  eight full business days thereafter as  the
Representatives  and the  Company shall designate),  which date and  time may be
postponed by agreement between  the Representatives and  the Company (such  date
and time being herein called the "Closing Date"). Delivery of the Bonds shall be
made  to  the  Representatives  for  the  respective  accounts  of  the  several
Underwriters  against   payment  by   the  several   Underwriters  through   the
Representatives  of  the purchase  price thereof  to  or upon  the order  of the
Company by  certified or  official bank  check  or checks  payable in  New  York
Clearing  House (next day)  funds or, if  so indicated in  Schedule I hereto, in
federal (same day) funds. The Bonds  will be delivered in definitive  registered
form  except that, if for any reason the  Company is unable to deliver the Bonds
in definitive  form,  the  Company  reserves  the  right,  as  provided  in  the
Indenture,  to make delivery in temporary form. Any Bonds delivered in temporary
form will be exchangeable without charge for Bonds in definitive form. The Bonds
will be registered in the names of the Underwriters and in the principal amounts
set forth in Schedule II  hereto except that if  the Company receives a  written
request  from  the  Representatives prior  to  noon  on the  third  business day
preceding the  Closing Date  giving  the names  in which  the  Bonds are  to  be
registered  and the  principal amounts  thereof (which shall  in each  case be a
multiple of $1,000) the Company will deliver the Bonds so registered. The  Bonds
will  be made  available to  the Representatives for  checking in  New York, New
York, not  later  than 2:00  p.m.,  New York  City  time, on  the  business  day
preceding the Close Date.

                                       4

    4.  AGREEMENTS.  The Company agrees with the several Underwriters that:

        (a)  With the consent of the Representatives, the Company will cause the
    Prospectus Supplement to be filed pursuant  to Rule 424 (b) and/or Rule  434
    under  the Act and will notify  the Representatives promptly of such filing.
    During the period for which a  prospectus relating to the Bonds is  required
    to  be  delivered  under  the  Act, the  Company  will  promptly  advise the
    Representatives (i) when any amendment  to the Registration Statement  shall
    have become effective, (ii) when any subsequent supplement to the Prospectus
    (including  documents  deemed  to  be  incorporated  by  reference  into the
    Prospectus) has been filed, (iii) of  any request by the Commission for  any
    amendment  of or supplement to the  Registration Statement or the Prospectus
    or for  any  additional  information,  and  (iv)  of  the  issuance  by  the
    Commission   of  any  stop   order  suspending  the   effectiveness  of  the
    Registration Statement or the institution or threatening of any  proceedings
    for   that  purpose.  The  Company  will  not  file  any  amendment  of  the
    Registration Statement or supplement to the Prospectus (including  documents
    deemed  to  be incorporated  by reference  into  the Prospectus)  unless the
    Company has furnished to the Representatives a copy for your review prior to
    filing and will not file any such proposed amendment or supplement to  which
    the Representatives reasonably object. The Company will use its best efforts
    to  prevent the issuance of any such stop order and, if issued, to obtain as
    soon as possible the withdrawal thereof.

        (b) If, at any time when a prospectus relating to the Bonds is  required
    to  be delivered under  the Act, any event  occurs as a  result of which the
    Prospectus  as  then  amended  or  supplemented  would  include  any  untrue
    statement of a material fact or omit to state any material fact necessary to
    make  the statements therein, in the  light of the circumstances under which
    they were made, not misleading, or if  it shall be necessary at any time  to
    amend  or supplement the Prospectus  to comply with the  Act or the Exchange
    Act or the respective  rules and regulations  of the Commission  thereunder,
    the  Company  promptly, subject  to paragraph  (a) of  this Section  4, will
    prepare and  file an  amendment or  supplement to  the Prospectus  with  the
    Commission  or will make a filing with the Commission pursuant to Section 13
    or 14 of the Exchange Act, which will correct such statement or omission  or
    will effect such compliance.

        (c)  The Company will  make generally available  to its security holders
    and to the Representatives a consolidated earnings statement (which need not
    be audited) of the  Company, for a twelve-month  period beginning after  the
    date  of the Prospectus Supplement filed pursuant to Rule 424(b) and/or Rule
    434 under the Act,  as soon as  is reasonably practicable  after the end  of
    such  period,  but in  any event  no  later than  eighteen months  after the
    "effective date of the  Registration Statement" (as  defined in Rule  158(c)
    under the Act), which will satisfy the provision of Section 11(a) of the Act
    and the rules and regulations of the Commission thereunder (including at the
    option of the Company, Rule 158).

        (d)  The Company  will furnish to  each of the  Representatives a signed
    copy of the Registration Statement as originally filed and of each amendment
    thereto, including the Form T-1 of  the Trustee and all powers of  attorney,
    consents  and exhibits filed therewith  (other than exhibits incorporated by
    reference), and will deliver to the Representatives conformed copies of  the
    Registration Statement, the Prospectus (including all documents incorporated
    by  reference  therein) and,  so  long as  delivery  of a  prospectus  by an
    Underwriter or dealer  may be  required by the  Act, all  amendments of  and
    supplements to such documents, in each case as soon as available and in such
    quantities as the Representatives may reasonably request.

        (e)  The Company will furnish such information, execute such instruments
    and take such action as may be required to qualify the Bonds for sale  under
    the laws of such jurisdictions as the Representatives may designate and will
    maintain  such  qualifications  in  effect  so  long  as  required  for  the
    distribution of the Bonds; PROVIDED that  the Company shall not be  required
    to  qualify  to do  business  in any  jurisdiction where  it  is not  now so
    qualified or  to  take any  action  which would  subject  it to  general  or
    unlimited  service of  process in  any jurisdiction where  it is  not now so
    subject.

        (f) So long as the Bonds  are outstanding, the Company will furnish  (or
    cause  to be furnished) to each of the Representatives, upon request, copies
    of (i) all reports to stockholders of  the Company and (ii) all reports  and
    financial  statements filed with  the Commission or  any national securities
    exchange.

                                       5
<PAGE>
        (g) During the  period beginning  from the  date of  this Agreement  and
    continuing  to  the  Closing Date,  the  Company  will not  offer,  sell, or
    otherwise dispose of any first mortgage  bonds of the Company (except  under
    prior contractual commitments which have been disclosed to you), without the
    prior  written consent  of the Representatives,  which consent  shall not be
    unreasonably withheld.

    5.  EXPENSES.   Whether or not the  transactions contemplated hereunder  are
consummated  or this Agreement is terminated, the Company will pay all costs and
expenses  incident  to  the  performance  of  the  obligations  of  the  Company
hereunder,  including,  without limiting  the generality  of the  foregoing, all
costs, taxes and expenses incident to the issue and delivery of the Bonds to the
Underwriters, all fees and  expenses of the  Company's counsel and  accountants,
all  costs and expenses  incident to the  preparing, printing and  filing of the
Registration  Statement  (including  all   exhibits  thereto),  the   Prospectus
(including  all documents incorporated by  reference therein) and any amendments
thereof or  supplements thereto,  all  costs and  expenses (including  fees  and
expenses  of counsel) incurred in connection with "blue sky" qualifications, the
determination of  the legality  of  the Bonds  for investment  by  institutional
investors  and  the rating  of  the Bonds,  and all  costs  and expenses  of the
printing and distribution of all documents in connection with this underwriting.
Except as provided in this Section 5 and Section 8 hereof, the Underwriters will
pay all their own costs  and expenses, including the  fees of their counsel  and
any advertising expenses in connection with any offer they may make.

    6.   CONDITIONS TO THE OBLIGATIONS OF  THE UNDERWRITERS.  The obligations of
the Underwriters to purchase  the Bonds shall be  subject, in the discretion  of
the  Representatives, to the  accuracy of the  representations and warranties on
the part of the Company contained herein  as of the date hereof and the  Closing
Date,  to  the  accuracy of  the  statements  of Company  officers  made  in any
certificates given pursuant to the provisions hereof, to the performance by  the
Company of its obligations hereunder and to the following additional conditions:

        (a)  The Prospectus  Supplement relating  to the  Bonds shall  have been
    filed with the Commission pursuant to Rule 424(b) and/or Rule 434 within the
    applicable  time  period  prescribed  for  such  filing  by  the  rules  and
    regulations  under the  Act and in  accordance with Section  4(a) hereof; no
    stop order suspending the effectiveness of the Registration Statement or any
    part thereof shall have been issued and no proceeding for that purpose shall
    have been initiated or  threatened by the Commission;  and all requests  for
    additional  information  on  the  part of  the  Commission  shall  have been
    complied with to the Representatives' reasonable satisfaction.

        (b) The  Representatives shall  be furnished  with opinions,  dated  the
    Closing  Date,  of  Gary R.  Johnson,  Vice President,  General  Counsel and
    Corporate Secretary of the  Company, substantially in  the form included  as
    Exhibit A.

        (c)  The  Representatives shall  have  received from  Gardner,  Carton &
    Douglas, Chicago, Illinois,  counsel for the  Underwriters, such opinion  or
    opinions  dated the  Closing Date with  respect to the  incorporation of the
    Company, this  Agreement, the  validity  of the  Indenture, the  Bonds,  the
    Registration  Statement,  the Prospectus  and other  related matters  as the
    Representatives may reasonably require, and the Company shall have furnished
    to such counsel such documents as they reasonably request for the purpose of
    enabling them to pass upon such matters.

        (d)  The  Company  shall  have   furnished  to  the  Representatives   a
    certificate of the President or any Vice President of the Company, dated the
    Closing  Date, as  to the matters  set forth in  clause (a) and  (h) of this
    Section 6 and  to the further  effect that the  signers of such  certificate
    have  carefully examined the Registration Statement, the Prospectus and this
    Agreement and that:

           (i) the  representations  and  warranties  of  the  Company  in  this
       Agreement  are true and  correct on and  as of the  Closing Date with the
       same effect as if made on the Closing Date, and the Company has  complied
       with  all the agreements and satisfied all  the conditions on its part to
       be performed or satisfied at or prior to the Closing Date; and

                                       6
<PAGE>
           (ii) there has been  no material adverse change  in the condition  of
       the  Company  and  its  subsidiaries  taken  as  a  whole,  financial  or
       otherwise, or  in the  earnings,  affairs or  business prospects  of  the
       Company  and its subsidiaries taken as a whole, whether or not arising in
       the ordinary course of business, from  that set forth or contemplated  by
       the Registration Statement or Prospectus Supplement.

        (e)  The Representatives shall have  received letters from the Company's
    independent public accountants (dated the date of this Agreement and Closing
    Date,  respectively,  and  in  form   and  substance  satisfactory  to   the
    Representatives)  advising that (i) they  are independent public accountants
    as required by the Act and published rules and regulations of the Commission
    thereunder, (ii) in their opinion, the consolidated financial statements and
    supplemental  schedules  incorporated  by  reference  in  the   Registration
    Statement  and  covered by  their opinion  filed  with the  Commission under
    Section 13 of the Exchange  Act comply as to  form in all material  respects
    with  the applicable  accounting requirements  of the  Exchange Act  and the
    published rules and  regulations of  the Commission  thereunder, (iii)  they
    have  performed limited procedures,  not constituting an  audit, including a
    reading of the latest available interim financial statements of the  Company
    and  its consolidated subsidiaries, a reading  of the minutes of meetings of
    the Board of Directors, committees thereof, and of the Shareholders, of  the
    Company  and  its subsidiaries  since the  date of  the most  recent audited
    financial  statements  included   or  incorporated  by   reference  in   the
    Prospectus,  inquiries  of officials  of  the Company  and  its subsidiaries
    responsible for financial  accounting matters and  such other inquiries  and
    procedures  as may  be specified in  such letter,  and on the  basis of such
    limited review and procedures  nothing came to  their attention that  caused
    them  to believe that: (a) any material  modifications should be made to any
    unaudited consolidated  financial  statements  of the  Company  included  or
    incorporated  by reference in  the Registration Statement  or Prospectus for
    them to be in  conformity with generally  accepted accounting principles  or
    any  unaudited consolidated financial statements  of the Company included or
    incorporated by reference in the Registration Statement or Prospectus do not
    comply as to form  in all material respects  with the applicable  accounting
    requirements  of  the Exchange  Act  and the  rules  and regulations  of the
    Commission  applicable  to  Form  10-Q;  (b)  with  respect  to  the  period
    subsequent  to the date of the  most recent financial statements included or
    incorporated by reference in  the Prospectus and except  as set forth in  or
    contemplated  by the  Registration Statement  or Prospectus,  there were any
    changes, at a specified date not more  than five business days prior to  the
    date  of  the letter,  in the  capital  stock of  the Company,  increases in
    long-term debt or decreases in stockholders' equity or net current assets of
    the Company and its consolidated  subsidiaries as compared with the  amounts
    shown on the most recent consolidated balance sheet included or incorporated
    in  the  Prospectus, or  for the  period from  the date  of the  most recent
    financial statements included or incorporated by reference in the Prospectus
    to such  specified date  there  were any  decreases,  as compared  with  the
    corresponding period in the preceding year, in operating revenues, operating
    income, net income, or earnings per share of Common Stock of the Company and
    its subsidiaries, except in all instances for changes or decreases set forth
    in  such  letter,  in which  case  the  letter shall  be  accompanied  by an
    explanation by  the  Company as  to  the significance  thereof  unless  said
    explanation  is not deemed necessary by  the Representatives; (iv) they have
    carried out  specified procedures  performed for  the purpose  of  comparing
    certain specified financial information and percentages (which is limited to
    financial  information  derived  from  general  accounting  records  of  the
    Company) included or incorporated by reference in the Registration Statement
    and Prospectus  with  indicated  amounts  in  the  financial  statements  or
    accounting  records of  the Company  and (excluding  any questions  of legal
    interpretation) have  found  such  information  and  percentages  to  be  in
    agreement  with  the relevant  accounting and  financial information  of the
    Company referred to  in such  letter in  the description  of the  procedures
    performed  by them and  (v) on the basis  of a reading  of the unaudited pro
    forma financial information  incorporated by reference  in the  Registration
    Statement and the Prospectus, carrying out certain specified procedures that
    would  not necessarily  reveal matters of  significance with  respect to the
    comments set forth in this paragraph (v), inquiries of certain officials  of
    the Company who have responsibility for financial and accounting matters and
    proving  the  arithmetic  accuracy  of  the  application  of  the  pro forma
    adjustments to the historical amounts  in the unaudited pro forma  financial
    information,  nothing came  to their attention  that caused  them to believe
    that the

                                       7
<PAGE>
unaudited  pro  forma  financial information  does  not  comply in  form  in all
material respects with the applicable  accounting requirements of Rule 11-02  of
Regulation  S-X or that the pro forma adjustments have not been properly applied
to the historical amounts in the compilation of such information.

        (f) Subsequent to the respective dates as of which information is  given
    in  the Registration Statement and the Prospectus, there shall not have been
    any change or  decrease specified in  the letter or  letters referred to  in
    paragraph (e) of this Section 6 which makes it impractical or inadvisable in
    the  judgment of the Representatives to  proceed with the public offering or
    the delivery of the Bonds on the terms and in the manner contemplated by the
    Prospectus.

        (g) Subsequent to the date  hereof, no downgrading shall have  occurred,
    nor  shall  any  notice  have  been  given  of  any  intended  or  potential
    downgrading or of any  review for a possible  change that does not  indicate
    the  direction of the possible change,  in the rating accorded the Company's
    debt securities or preferred stock by any "nationally recognized statistical
    rating organization," as that term is defined by the Commission for purposes
    of Rule 436(g)(2) under the Act.

        (h) (i)  Neither the  Company nor  any of  its subsidiaries  shall  have
    sustained since the date of the latest audited financial statements included
    or incorporated by reference in the Prospectus any loss or interference with
    its  business from fire, explosion, flood  or other calamity, whether or not
    covered by insurance,  or from any  labor dispute or  court or  governmental
    action,  order or decree, otherwise than as set forth or contemplated in the
    Prospectus Supplement, and (ii)  since the date  of this Agreement,  neither
    the  Company nor any of its subsidiaries shall have incurred any liabilities
    or obligations, direct or contingent, or entered into any transactions,  not
    in  the ordinary course of  business, which are material  to the Company and
    its subsidiaries, and there  shall not have been  any change in the  capital
    stock  or long-term debt  of the Company  or any of  its subsidiaries or any
    change, or any development involving  a prospective change, in or  affecting
    the general affairs, management, financial position, stockholders' equity or
    results  of operations of the Company and its subsidiaries otherwise than as
    set forth or contemplated in the Prospectus Supplement, the effect of which,
    in any such case described in clause (i)  or (ii) is in the judgment of  the
    Underwriters  so  material  and  adverse  as  to  make  it  impracticable or
    inadvisable to proceed with the public offering or the delivery of the Bonds
    on the terms and in the manner contemplated by the Prospectus.

        (i)  No  Representative  shall  have   advised  the  Company  that   the
    Registration  Statement  or  Prospectus,  or  any  amendment  or  supplement
    thereto, contains  an untrue  statement  of fact  which  in the  opinion  of
    counsel  for the Underwriters is material or  omits to state a fact which in
    the opinion of counsel for the  Underwriters is material and is required  to
    be  stated  therein  or is  necessary  to  make the  statements  therein not
    misleading.

        (j) Prior to the Closing Date,  the Company shall have furnished to  the
    Representatives such further information, certificates and documents as they
    may reasonably request.

    If  any of the  conditions specified in  this Section 6  shall not have been
fulfilled when and as required by this Agreement, or if any of the opinions  and
certificates  mentioned  above  or  elsewhere in  this  Agreement  shall  not be
satisfactory in form  and substance  to the Representatives  and their  counsel,
this  Agreement  and  all  obligations  of  the  Underwriters  hereunder  may be
cancelled at, or at any time prior to, the Closing Date by the  Representatives.
Notice  of such  cancellation shall be  given to  the Company in  writing, or by
telephone or telegraph confirmed in writing.

    7.  CONDITIONS OF COMPANY'S OBLIGATIONS.  The obligations of the Company  to
sell and deliver the Bonds are subject to the following conditions:

        (a)   Prior  to  the   Closing  Date,  no   stop  order  suspending  the
    effectiveness of the Registration  Statement shall have  been issued and  no
    proceedings for that purpose shall have been instituted or, to the knowledge
    of the Company or the Representative, threatened.

        (b)  The order of the Minnesota  Public Utilities Commission referred to
    in paragraph (1) of Section 1 shall be in full force and effect.

                                       8
<PAGE>
    If any of the  conditions specified in  this Section 7  shall not have  been
fulfilled,  this Agreement and  all obligations of the  Company hereunder may be
cancelled on or at any time prior to the Closing Date by the Company. Notice  of
such  cancellation shall be given to the Underwriters in writing or by telephone
or facsimile transmission confirmed in writing.

    8.   REIMBURSEMENT OF  UNDERWRITERS' EXPENSES.   If  the sale  of the  Bonds
provided  for herein is not consummated because any condition to the obligations
of the Underwriters set forth in Section 6 hereof is not satisfied or because of
any refusal, inability  or failure on  the part  of the Company  to perform  any
agreement  herein or comply with any provision hereof, other than by reason of a
default by any of the Underwriters, the Company will reimburse the  Underwriters
severally  upon  demand  for all  out-of-pocket  expenses that  shall  have been
reasonably incurred by them in connection with the proposed purchase and sale of
the Bonds.

    9.  INDEMNIFICATION.  (a) The Company agrees to indemnify and hold  harmless
each Underwriter and each person who controls any Underwriter within the meaning
of  either  the Act  or the  Exchange Act  against any  and all  losses, claims,
damages or liabilities,  joint or  several, to  which they  or any  of them  may
become  subject  under the  Act,  the Exchange  Act  or other  federal  or state
statutory law or regulation, at common law or otherwise insofar as such  losses,
claims,  damages or liabilities (or actions in  respect thereof) arise out of or
are based upon any  untrue statement or alleged  untrue statement of a  material
fact  contained in the registration statement  for the registration of the Bonds
as originally filed or in any amendment thereof, or in the Prospectus or in  any
amendment  thereof or supplement thereto, or arise  out of or are based upon the
omission or alleged  omission to state  therein a material  fact required to  be
stated  therein or necessary  to make the statements  therein not misleading and
agrees to reimburse each such indemnified party for any legal or other  expenses
as reasonably incurred by them in connection with investigating or defending any
such  loss, claim, damages, liability or  action; PROVIDED that the Company will
not be liable in any such case to  the extent that any such loss, claim,  damage
or liability arises out of or is based upon any such untrue statement or alleged
untrue  statement or omission or alleged  omission made therein in reliance upon
and in conformity  with written information  furnished to the  Company by or  on
behalf  of  any Underwriter  through  the Representatives  specifically  for use
therein and PROVIDED FURTHER  that such indemnity with  respect to a  prospectus
included  in the  registration statement or  any amendment thereto  prior to the
supplementing thereof  with the  Prospectus Supplement  shall not  inure to  the
benefit  of any  Underwriter (or any  person controlling  such Underwriter) from
whom the person asserting  any such loss, claim,  damage or liability  purchased
the  Bonds which are the subject thereof if  such person was not sent or given a
copy of  the Prospectus  (but without  the documents  incorporated by  reference
therein)  at or  prior to  the confirmation of  the sale  of such  Bonds to such
person in any case  where such delivery  is required by the  Act and the  untrue
statement  or  omission of  a  material fact  contained  in such  prospectus was
corrected in the Prospectus, provided that the Company shall have delivered  the
Prospectus,  in  a timely  manner and  in sufficient  quantities to  permit such
delivery by the Underwriters.  This indemnity agreement will  be in addition  to
any liability which the Company may otherwise have.

    (b)  Each Underwriter  severally agrees to  indemnify and  hold harmless the
Company, each  of  its  directors, each  of  its  officers who  has  signed  the
Registration  Statement and each person, if any, who controls the Company within
the meaning of either  the Act or the  Exchange Act, to the  same extent as  the
foregoing indemnity from the Company to the Underwriters but only with reference
to  written  information  furnished to  the  Company  by or  on  behalf  of such
Underwriter through the  Representatives specifically for  use in the  documents
referred  to  in the  foregoing  indemnity, and  agrees  to reimburse  each such
indemnified party for any legal or other expenses reasonably incurred by them in
connection with  investigating  or  defending  any  such  loss,  claim,  damage,
liability  or  action.  This indemnity  agreement  will  be in  addition  to any
liability which any Underwriter may otherwise have.

    (c) Promptly after receipt by an  indemnified party under this Section 9  of
notice  of the  commencement of  any action, such  indemnified party  will, if a
claim in respect thereof is to be made against the indemnifying party under this
Section 9, notify the indemnifying party in writing of the commencement thereof;
but the omission to so  notify the indemnifying party  will not relieve it  from
any  liability which it may  have to any indemnified  party otherwise than under
this Section  9. In  case any  such action  is brought  against any  indemnified
party,  and it notifies the indemnifying  party of the commencement thereof, the
indemnifying

                                       9
<PAGE>
party will be entitled to  participate therein, and, to  the extent that it  may
elect  by  written  notice delivered  to  the indemnified  party  promptly after
receiving the  aforesaid  notice from  such  indemnified party,  to  assume  the
defense  thereof, with counsel satisfactory  to such indemnified party; PROVIDED
THAT if the defendants in any such action include both the indemnified party and
the indemnifying party and the indemnified party shall have reasonably concluded
that there  may be  legal  defenses available  to  it and/or  other  indemnified
parties  which  are  different from  or  additional  to those  available  to the
indemnifying party, the indemnified  party, or parties shall  have the right  to
select  separate  counsel  to  assume  such  legal  defenses  and  to  otherwise
participate in the defense of such action on behalf of such indemnified party or
parties. Upon receipt of notice from the indemnifying party to such  indemnified
party  of its election so  to assume the defense of  such action and approval by
the indemnified party of counsel, the  indemnifying party will not be liable  to
such  indemnified party  under this  Section 9 for  any legal  or other expenses
subsequently incurred by such indemnified  party in connection with the  defense
thereof unless (i) the indemnified party shall have employed separate counsel in
connection  with the assertion of legal  defenses in accordance with the proviso
to  the  next  preceding  sentence  (it  being  understood,  however,  that  the
indemnifying  party  shall not  be  liable for  the  expenses of  more  than one
separate counsel and one local counsel,  approved by the Representatives in  the
case   of  subparagraph   (a),  representing   the  indemnified   parties  under
subparagraphs (a) or (b), as the case  may be, who are parties to such  action),
(ii)  the indemnifying party shall not have employed counsel satisfactory to the
indemnified party to represent  the indemnified party  within a reasonable  time
after  notice of commencement of the action  or (iii) the indemnifying party has
authorized the employment of counsel for the indemnified party at the expense of
the indemnifying party; and except that,  if clause (i) or (iii) is  applicable,
such  liability shall  be only  in respect  of the  counsel referred  to in such
clause (i) or (iii).

    (d) If the indemnification provided for in this Section 9 is unavailable  to
or  insufficient to hold  harmless an indemnified party  under subsection (a) or
(b) above in respect of any  losses, claims, damages or liabilities (or  actions
in  respect thereof)  referred to  therein, then  each indemnifying  party shall
contribute to the amount paid or payable  by such indemnified party as a  result
of  such losses, claims, damages or  liabilities (or actions in respect thereof)
in such proportion as is appropriate  to reflect the relative benefits  received
by  the Company  on the  one hand  and the  Underwriters on  the other  from the
offering of the Bonds. If, however,  the allocation provided by the  immediately
preceding  sentence is  not permitted  by applicable  law or  if the indemnified
party failed to give the notice  required under subsection (c) above, then  each
indemnifying  party  shall contribute  to such  amount paid  or payable  by such
indemnified party in such proportion as is appropriate to reflect not only  such
relative benefits but also the relative fault of the Company on the one hand and
the  Underwriters on  the other in  connection with the  statements or omissions
which resulted in  such losses, claims,  damages or liabilities  (or actions  in
respect  thereof), as well  as any other  relevant equitable considerations. The
relative benefits received by the Company  on the one hand and the  Underwriters
on  the other  shall be deemed  to be  in the same  proportion as  the total net
proceeds from the offering (before  deducting expenses) received by the  Company
bear  to  the  total  underwriting discounts  and  commissions  received  by the
Underwriters, in each case as  set forth in the table  on the cover page of  the
Prospectus  Supplement. The relative fault shall  be determined by reference to,
among other things, whether the untrue or alleged untrue statement of a material
fact or the omission  or alleged omission  to state a  material fact relates  to
information  supplied by the Company on the  one hand or the Underwriters on the
other and the  parties' relative  intent, knowledge, access  to information  and
opportunity  to correct or  prevent such statement or  omission. The Company and
the Underwriters agree that it would not be just and equitable if  contributions
pursuant  to this subsection (d) 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  subsection (d).  The amount  paid or  payable by an
indemnified party as a result of the losses, claims, damages or liabilities  (or
actions  in respect thereof) referred  to above in this  subsection (d) shall be
deemed to  include any  legal  or other  expenses  reasonably incurred  by  such
indemnified  party in connection with investigating or defending any such action
or claim. Notwithstanding the provisions of this subsection (d), no  Underwriter
shall  be required to contribute any amount in excess of the amount by which the
total price at which the Bonds 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  such untrue  or
alleged  untrue statement or  omission or alleged omission.  No person guilty of
fraudulent misrepresentation (within the meaning of

                                       10
<PAGE>
Section 11(f) of the Act) shall be entitled to contribution from any person  who
was   not  guilty  of  such   fraudulent  misrepresentation.  The  Underwriters'
obligations in this subsection  (d) to contribute are  several in proportion  to
their respective underwriting obligations and not joint.

    (e) The obligations of the Company under this Section 9 shall be in addition
to any liability which the Company may otherwise have and shall extend, upon the
same  terms and conditions, to each person, if any, who controls any Underwriter
within the meaning  of the Act;  and the obligations  of the Underwriters  under
this  Section  9 shall  be in  addition  to any  liability which  the respective
Underwriters may  otherwise have  and  shall extend,  upon  the same  terms  and
conditions,  to each officer and director of  the Company and to each person, if
any, who controls the Company within the meaning of the Act.

    10.  DEFAULT BY AN UNDERWRITER.  (a) If any Underwriter shall default in its
obligation to purchase the Bonds which  it has agreed to purchase hereunder  (in
this  Section called the "Unpurchased Bonds"),  the Representatives may in their
discretion arrange for themselves or another party or other parties to  purchase
such Unpurchased Bonds on the terms contained herein. If within thirty-six hours
after such default by any Underwriter the Representatives do not arrange for the
purchase  of such  Unpurchased Bonds,  then the Company  shall be  entitled to a
further period of  thirty-six hours  within which  to procure  another party  or
other  parties satisfactory to the  Representatives to purchase such Unpurchased
Bonds on such terms. In the event that, within the respective prescribed period,
the Representatives  notify the  Company  that they  have  so arranged  for  the
purchase  of such Unpurchased Bonds, or the Company notifies the Representatives
that it  has  so  arranged for  the  purchase  of such  Unpurchased  Bonds,  the
Representatives or the Company shall have the right to postpone the Closing Date
for such Unpurchased Bonds for a period of not more than seven days, in order to
effect  whatever  changes  may thereby  be  made necessary  in  the Registration
Statement or  the  Prospectus  as  amended or  supplemented,  or  in  any  other
documents  or  arrangements,  and  the  Company  agrees  to  file  promptly  any
amendments or supplements to the Registration Statement or the Prospectus  which
in  the opinion of the  Representatives may thereby be  made necessary. The term
"Underwriter" as used  in this  Agreement shall include  any person  substituted
under  this Section  with like effect  as if  such person had  originally been a
party to this Agreement with respect to such Unpurchased Bonds.

    (b) If, after  giving effect  to any arrangements  for the  purchase of  the
Unpurchased   Bonds  of  a   defaulting  Underwriter  or   Underwriters  by  the
Representatives and  the  Company  as  provided in  subsection  (a)  above,  the
aggregate  principal amount of such  Unpurchased Bonds which remains unpurchased
does not exceed  one-eleventh of the  aggregate principal amount  of the  Bonds,
then the Company shall have the right to require each non-defaulting Underwriter
to  purchase  the principal  amount of  Bonds which  such Underwriter  agreed to
purchase hereunder and, in addition, to require each non-defaulting  Underwriter
to  purchase its pro  rata share (based  on the principal  amount of Bonds which
such Underwriter agreed to purchase hereunder) of the Unpurchased Bonds of  such
defaulting Underwriter or Underwriters for which such arrangements have not been
made;  but nothing herein shall relieve  a defaulting Underwriter from liability
for its default.

    (c) If, after  giving effect  to any arrangements  for the  purchase of  the
Unpurchased   Bonds  of  a   defaulting  Underwriter  or   Underwriters  by  the
Representatives and  the  Company  as  provided in  subsection  (a)  above,  the
aggregate  principal  amount  of  Unpurchased  Bonds  which  remains unpurchased
exceeds one-eleventh of the aggregate principal amount of the Bonds, as referred
to in subsection  (b) above,  or if  the Company  shall not  exercise the  right
described  in  subsection (b)  above to  require non-defaulting  Underwriters to
purchase Unpurchased Bonds  of a  defaulting Underwriter  or Underwriters,  then
this  Agreement shall thereupon terminate, without  liability on the part of any
non-defaulting Underwriter or the Company, except  for the expenses to be  borne
by  the Company  and the Underwriters  as provided  in Section 5  hereof and the
indemnity and contribution agreements  in Section 9  hereof; but nothing  herein
shall relieve a defaulting Underwriter from liability for its default.

    11.   TERMINATION.   This Agreement shall  be subject to  termination in the
absolute discretion of the Representatives, by notice given to the Company prior
to delivery of and payment for all Bonds,  if prior to such time (i) trading  in
securities generally on the New York Stock Exchange shall have been suspended or
limited  or minimum prices shall have been established on such Exchange, (ii) if
a banking moratorium shall  have been declared either  by Federal, Minnesota  or
New York State authorities, (iii) if trading in any

                                       11
<PAGE>
securities  of the Company shall have been suspended or halted, or (iv) if there
shall have  occurred any  outbreak or  escalation of  hostilities involving  the
United  States or  the declaration  by the  United States  of a  war or national
emergency or any other calamity or crisis  the effect of which on the  financial
markets  in the  United States is  such as  to make it,  in the  judgment of the
Representatives,  impracticable  or  inadvisable  to  proceed  with  the  public
offering or delivery of the Bonds on the terms and in the manner contemplated in
the Prospectus.

    12.   REPRESENTATIONS AND  INDEMNITIES TO SURVIVE  DELIVERY.  The respective
agreements, representations, warranties, indemnities and other statements of the
Company or its officers and of the Underwriters set forth in or made pursuant to
this Agreement  will  remain  in  full  force  and  effect,  regardless  of  any
investigation  made by or on behalf of any  Underwriter or the Company or any of
their respective officers, directors or  controlling persons within the  meaning
of  the  Act,  and will  survive  delivery of  and  payment for  the  Bonds. The
provisions of  Sections 5,  8 and  9  hereof shall  survive the  termination  or
cancellation of this Agreement.

    13.   NOTICES.  All communications hereunder will be in writing and, if sent
to the Representatives, will be  mailed, delivered or transmitted and  confirmed
to  them at their address set forth for that purpose in Schedule 1 hereto or, if
sent to the Company, will be  mailed, delivered or transmitted and confirmed  to
it at 414 Nicollet Mall, Minneapolis, Minnesota 55401, attention Secretary.

    14.  SUCCESSORS.  This Agreement will inure to the benefit of and be binding
upon  the parties  hereto and their  respective successors and  the officers and
directors and controlling persons referred to in Section 9 hereof, and no  other
person will have any right or obligation hereunder.

    15.   APPLICABLE LAW.   This Agreement will be  governed by and construed in
accordance with the laws of the State of Minnesota.

    16.  COUNTERPARTS.  This Agreement  may be executed in counterparts, all  of
which,  taken together, shall constitute a single agreement among the parties to
such counterparts.

    17.  REPRESENTATION OF THE UNDERWRITERS.  The Representatives represent  and
warrant to the Company that they are authorized to act as the representatives of
the Underwriters in connection with this financing and that the Representatives'
execution  and delivery  of this Agreement  and any action  under this Agreement
taken by such Representatives will be binding upon all Underwriters.

    18.   OTHER.   Time  shall  be  of the  essence  for all  purposes  of  this
Agreement.  As  used  herein,  "business  day"  shall  mean  any  day  when  the
Commission's office in Washington D.C. is open for business.

                       FORM OF OPINION OF GARY R. JOHNSON
      RE: $           PRINCIPAL AMOUNT OF FIRST MORTGAGE BONDS, SERIES DUE
                                           ,    %
           OF NORTHERN STATES POWER COMPANY, A MINNESOTA CORPORATION.

Gentlemen:

    For  the purpose of rendering this  opinion, I have examined the proceedings
taken by Northern States Power  Company, a Minnesota corporation, herein  called
the "Company," with respect to the issue and sale by the Company of $
principal  amount of First Mortgage Bonds, Series due              ,    % herein
called  the  "Bonds."  In  connection  therewith  I  have  participated  in  the
preparation  of the proceedings for the issuance and sale of the Bonds including
the Underwriting Agreement dated                  , between you and the  Company
relating  to your purchase of the Bonds, herein called the "Agreement," and have
either participated in the preparation of or examined the Trust Indenture  dated
February  1,  1937,  and  the  Supplemental  Trust  Indentures  thereto  and the
Supplemental Trust Indenture dated as of                  , creating the  Bonds,
all  from the Company to Harris Trust  and Savings Bank, as Trustee (which Trust
Indenture and Supplemental Trust Indentures  are herein collectively called  the
"Indenture").  I also  have participated in  the preparation of  or examined the
registration  statement  and  any   amendments  thereto  and  the   accompanying
prospectuses  and any supplements thereto, as  filed under the Securities Act of
1933, as amended  (the "Act"),  with respect to  the Bonds.  Whenever the  terms
"Registration  Statement" or "Prospectus"  are used herein,  they shall have the
respective meanings set forth in the  Agreement. My examination has extended  to
all  statutes, records, instruments, and documents which I have deemed necessary
to examine for the purposes of this opinion.

    I am of the opinion that:

        1. The Company is a legally  existing corporation under the laws of  the
    State of Minnesota; has corporate power, right, and authority to do business
    and  to own  property in  the states of  Minnesota, North  Dakota, and South
    Dakota in  the manner  and as  set forth  in the  Prospectus; has  corporate
    power,  right and authority  to own securities of  its subsidiaries; and has
    corporate power, right, and  authority to make the  Indenture and issue  and
    sell the Bonds;

        2.  The authorized capital stock  of the Company is  as set forth in the
    Prospectus and all of the issued shares of capital stock of the Company have
    been  duly  authorized   and  validly   issued  and  are   fully  paid   and
    non-assessable;

        3.  Each Significant  Subsidiary, as  defined in  the Agreement,  of the
    Company has been duly incorporated and is validly existing as a  corporation
    in good standing under the laws of the jurisdiction of its incorporation and
    is  duly qualified as a  foreign corporation to transact  business and is in
    good standing in each  jurisdiction in which it  owns or leases  substantial
    properties   or  in  which  the  conduct   of  its  business  requires  such
    qualification; all  of the  issued  and outstanding  capital stock  of  each
    subsidiary has been duly authorized and validly issued and is fully paid and
    non-assessable;  and the capital stock of  each such subsidiary owned by the
    Company, directly or through  subsidiaries, is owned free  and clear of  any
    pledge, lien, encumbrance, claim or equity;

        4.  The Agreement has  been duly authorized,  executed, and delivered by
    the Company and is a valid and binding obligation of the Company, except  to
    the   extent  that  the  provisions  for  indemnities  may  be  held  to  be
    unenforceable as against public policy;

        5. The  Indenture  has been  duly  authorized by  appropriate  corporate
    proceedings on the part of the Company, has been duly executed and delivered
    and  constitutes  a  legal,  valid, and  binding  instrument  enforceable in
    accordance with its  terms, except as  the provisions of  the United  States
    Bankruptcy  Code may affect the validity of the lien thereof with respect to
    proceeds, products,  rents,  issues,  or profits  realized,  and  additional
    property  acquired, after  the commencement of  a case under  said Code, and
    except as enforcement of the provisions  of the Indenture may be limited  by
    the  laws of the states of Minnesota,  North Dakota, and South Dakota (where
    property covered thereby is located) affecting the

                                       1
<PAGE>
    remedies for the enforcement of the  security provided for in the  Indenture
    (which  state laws do  not in my  opinion make such  remedies inadequate for
    realization of the benefits of such security)  or except as the same may  be
    limited by bankruptcy or insolvency laws or other similar laws;

        6.  The  issuance of  the  Bonds in  accordance  with the  terms  of the
    Indenture and the sale  and delivery thereof pursuant  to the provisions  of
    the  Agreement have been duly authorized by the Company; the statements made
    under the captions "Description of New Bonds" and "Supplemental  Description
    of  Offered Bonds" in  the Prospectus, insofar as  they purport to summarize
    provisions of documents specifically referred to therein, fairly present the
    information called for with  respect thereto by Form  S-3; the Bonds are  in
    due  legal form,  constitute legal,  valid, and  binding obligations  of the
    Company, and (subject to the  qualifications expressed in paragraph 5  above
    with respect to the validity and enforceability of certain of the provisions
    of the Indenture) and enforceable in accordance with their terms;

        7.  The consummation of  the transactions contemplated  in the Agreement
    and the fulfillment of the terms thereof and compliance by the Company  with
    all the terms and provisions of the Indenture will not result in a breach of
    any  of  the terms  or provisions  of,  or constitute  a default  under, any
    indenture, mortgage, deed of trust or other agreement or instrument known to
    me to which the Company is a party or by which it is bound, or the  Restated
    Articles  of Incorporation, as amended, or by-laws of the Company or, to the
    best of  my knowledge,  any  order, rule  or  regulation applicable  to  the
    Company  of  any  court  or  of any  Federal  or  state  regulatory  body or
    administrative agency or  other governmental body  having jurisdiction  over
    the Company or its property;

        8.  The Registration Statement  has become effective  under the Act. The
    Prospectus Supplement (as defined in the Agreement) has been filed  pursuant
    to  Rule 424(b) under the Act, and no proceedings for a stop order have been
    instituted or to  the knowledge of  such counsel are  pending or  threatened
    under Section 8(d) of the Act; the Minnesota Public Utilities Commission has
    issued  its  order approving  the  Company's capital  structure  which order
    authorizes the issuance of the Bonds; the Indenture has been duly  qualified
    under  the Trust  Indenture Act  of 1939,  as amended  (the "Trust Indenture
    Act"); and no  further approval of,  authorization, consent, certificate  or
    order  of any  governmental body,  federal, state  or other,  is required in
    connection with the issuance and sale of the Bonds by the Company to you  as
    provided  in the  Agreement, except as  may be required  by state securities
    laws;

        9.  At  the  time  the  Registration  Statement  became  effective,  the
    Registration  Statement (other than the  financial statements and supporting
    schedules included  or incorporated  by reference  therein, as  to which  no
    opinion  is being  expressed) complied as  to form in  all material respects
    with the requirements of the Act, the rules and regulations thereunder,  the
    Trust Indenture Act and the rules and regulations thereunder;

        10.  I do not know of any  legal or governmental proceedings required to
    be described in the  Prospectus which are not  described as required nor  of
    any  contracts or documents of  a character required to  be described in the
    Registration Statement  or Prospectus  or to  be filed  as exhibits  to  the
    Registration Statement which are not described and filed as required;

        11.  The Indenture  is in  proper form,  conforming to  the laws  of the
    States of Minnesota, North Dakota, and South Dakota, to give and create  the
    lien  which it purports to create and has  been and now is duly and properly
    recorded or filed  in all  places necessary to  effectuate the  lien of  the
    Indenture;

        12.  The Company has good and valid title to all real and fixed property
    and leasehold rights described or  enumerated in the Indenture (except  such
    properties  as have been  released from the lien  thereof in accordance with
    the terms  thereof), subject  only to:  (a) taxes  and assessments  not  yet
    delinquent;  (b) the lien of the Indenture; (c) as to parts of the Company's
    property, certain easements, conditions,  restrictions, leases, and  similar
    encumbrances  which do not affect the Company's  use of such property in the
    usual course of its business, certain minor defects in titles which are  not
    material, defects in titles to certain properties which are not essential to
    the Company's business; and mechanics' lien claims being contested or not of
    record  or for the satisfaction or discharge of which adequate provision has
    been made by the Company pursuant to the Indenture;

        13. The  Bonds  are secured  by  and entitled  to  the benefits  of  the
    Indenture  equally and ratably,  except as to  sinking fund provisions, with
    all   other    bonds    duly    issued    and    outstanding    under    the

                                       2
<PAGE>
    Indenture  by a valid and direct first mortgage lien of the Indenture on all
    of the real and fixed properties, leasehold rights, franchises, and  permits
    now  owned  by the  Company,  subject only  to the  items  set forth  in the
    preceding paragraph 12 of this opinion;

        14. The Bonds also are secured equally and ratably, except as to sinking
    fund provisions, with all other bonds duly issued and outstanding under  the
    Indenture  by a valid  and direct first mortgage  lien (subject to permitted
    liens as defined in the Indenture) on all real and fixed property  hereafter
    acquired  by  the Company  in conformity  with the  terms of  the Indenture,
    except as the United States Bankruptcy  Code may affect the validity of  the
    lien of such Indenture on property acquired after the commencement of a case
    under  such  Act, except  as  to the  prior lien  of  the Trustee  under the
    Indenture in  certain  events specified  therein,  and except  as  otherwise
    provided  in the Indenture in the case of consolidation, merger, or transfer
    of all the mortgaged and pledged property as an entirety;

        15. The  Company has  all necessary  power under  statutory  provisions,
    franchises  (which  expire  at  various  dates),  or  permits  to  serve the
    customers in the jurisdictions where  it provided electric and gas  service,
    except in certain instances that are not material to the Company; and

        16.   All  statements  contained  in   the  Registration  Statement  and
    Prospectus under the caption  "Description of New  Bonds" purporting to  set
    forth  the opinion of counsel or purporting  to be based upon the opinion of
    counsel correctly set forth my opinion on said respective matters.

    These opinions do not cover titles  to easements for water flowage  purposes
or  rights of way for electric and gas transmission and distribution facilities,
steam mains, and telephone lines. However, the Company has the power of  eminent
domain in the states in which it operates.

    In  the course  of my participation  in the preparation  of the Registration
Statement and Prospectus I made investigations as to the accuracy of certain  of
the  statements  of  fact  contained therein,  I  discussed  other  matters with
officers, employees, and representatives of the Company, and I examined  various
corporate  records and data. While  I do not pass  upon or assume responsibility
for, and shall not  be deemed to have  independently verified, the accuracy  and
completeness  of  the  statements  contained in  the  Registration  Statement or
Prospectus (except as to matters set forth in paragraphs 9 and 16 above) nothing
has come to my  attention that would  lead me to  believe that the  Registration
Statement  at the time  it became effective  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  therein  not  misleading  or  that the
Prospectus as of the date  of the Agreement or at  the date hereof contained  an
untrue  statement  of  a material  fact  or  omitted to  state  a  material fact
necessary in order to make the statements therein, in light of the circumstances
under which they were made, not misleading.

    In  giving  my  opinion  under  paragraph  12  above,  I  have  relied  upon
examinations of abstracts of titles to properties of the Company, said abstracts
bearing  various dates, and nothing has come to my attention which would lead me
to believe that  anything has occurred  since the dates  of the abstracts  which
would  adversely affect the titles shown on the abstracts. In giving opinions as
to conformity  to  the  laws of  States  other  than Minnesota  and  as  to  the
franchises  and titles to property  of the Company, I  have in certain instances
relied upon the opinion of other counsel employed or retained by the Company  to
render opinions in respect thereto.

                                        Respectfully submitted,

                                        By

    NORTHERN  STATES POWER COMPANY,  a corporation organized  and existing under
the laws of the State of  Minnesota (the "Company"), for value received,  hereby
promises  to pay to                 or  registered assigns, at the office of the
Trustee, in Chicago, Illinois, or, at the option of the registered owner, at the

GLOBAL BONDS MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE BY THE DEPOSITORY OR BY  A
NOMINEE  OF THE DEPOSITORY TO THE DEPOSITORY, ANOTHER NOMINEE OF THE DEPOSITORY,
A SUCCESSOR OF THE DEPOSITORY OR A NOMINEE OF SUCH SUCCESSOR."]*

    This bond is one of a duly authorized issue of bonds of the Company, of  the
series  and  designation indicated  on  the face  hereof,  which issue  of bonds
consists, or may consist, of several series of varying denominations, dates, and
tenor, all issued and to be issued under and equally secured (except insofar  as
a  sinking fund, or similar fund,  established in accordance with the provisions
of the Indenture may  afford additional security for  the bonds of any  specific
series)  by a Trust Indenture dated February  1, 1937 (the "1937 Indenture"), as
supplemented by  supplemental trust indentures (collectively, the  "Supplemental
Indentures"), a Supplemental and Restated Trust Indenture dated May 1, 1988 (the
"Restated  Indenture") and a  new supplemental trust indenture  for the bonds of
this series  (the "New  Supplemental  Indenture"), executed  by the  Company  to
Harris  Trust and Savings Bank, as  Trustee (the "Trustee"). The 1937 Indenture,
as supplemented by the Supplemental  Indentures, the Restated Indenture and  the
New   Supplemental  Indenture  herein  are   referred  to  collectively  as  the
"Indenture". Reference hereby is made to the Indenture for a description of  the
property  mortgaged  and pledged,  the nature  and extent  of the  security, the
rights of  the holders  of the  bonds as  to such  security, and  the terms  and
conditions  upon  which the  bonds may  be  issued under  the Indenture  and are
secured. The  principal  hereof  may  be  declared or  may  become  due  on  the
conditions,  in the manner and at the time  set forth in the Indenture, upon the
happening of a default as in the Indenture provided.

    With the  consent of  the Company  and to  the extent  permitted by  and  as
provided  in the Indenture, the rights and obligations of the Company and of the
holders of the bonds, and the terms  and provisions of the Indenture and of  any
instruments  supplemental thereto may be modified or altered by affirmative vote
of the holders of at least 80% in principal amount of the bonds then outstanding
under the Indenture  and any instruments  supplemental thereto (excluding  bonds
challenged  and disqualified  from voting  by reason  of the  Company's interest
therein as provided in the Indenture); provided that without the consent of  all
holders  of all bonds  affected no such modification  or alteration shall permit
the extension of the maturity of the principal of

any  bond  or  the  reduction in  the  rate  of interest  thereon  or  any other
modification in  the  terms  of  payment of  such  principal  or  interest.  The
foregoing  80% requirement  will be reduced  to 66  2/3% when all  bonds of each
series issued under the Indenture prior to May 1, 1985, shall have been  retired
or all the holders thereof shall have consented to such reduction.

    The  Restated  Indenture  amends and  restates  the 1937  Indenture  and the
Supplemental Indentures.  The  Restated  Indenture  will  become  effective  and
operative  (the "Effective Date") when all Bonds of each series issued under the
Indenture prior  to May  1, 1988  shall  have been  retired through  payment  or
redemption (including those bonds "deemed to be paid" within the meaning of that
term as used in Article XVII of the 1937 Indenture) or until, subject to certain
exceptions,  the holders of  the requisite principal amount  of such bonds shall
have consented to the amendments contained in the Restated Indenture. Holders of
the bonds of this series and of each subsequent series of bonds issued under the
Indenture likewise will  be bound by  the amendments contained  in the  Restated
Indenture  when they  become effective and  operative. Reference is  made to the
Restated Indenture  for  a  complete description  of  the  amendments  contained
therein to the 1937 Indenture and to the Supplemental Indentures.

    The Company and the Trustee may deem and treat the person in whose name this
bond  is registered as  the absolute owner  hereof for the  purpose of receiving
payment and for all other  purposes and shall not be  affected by any notice  to
the contrary.

    [At  the option of the Company, and upon not less than 30 days' notice prior
to the date fixed for redemption, in the manner and with the effect provided  in
the  Indenture, any or all of the  bonds of this Series due             , may be
redeemed, other than for the Sinking Fund provided for bonds of this series,  by
the Company on any date by the payment of principal, the accrued interest to the
date of redemption, and the applicable premium on the principal amount specified
in the tabulation below under the heading "Regular Redemption Premium," provided
that no bond of the Series due           , shall be redeemed (other than through
said  Sinking Fund)  prior to               , and  this bond is  entitled to the
benefits of and is subject to call for redemption at par for the Sinking Fund on
December 1 of each year beginning     , upon like  notice and in the manner  and
with  the effect  provided in  the Indenture,  by the  payment of  principal and
accrued interest to the date of redemption:

    [Bonds of this series are not redeemable prior to maturity, for any  reason,
and are not subject to a sinking fund.]

    This  bond is transferable as prescribed  in the Indenture by the registered
owner hereof in person, or by his duly authorized attorney, at the office of the
Trustee in Chicago, Illinois, or at the option of the owner at the agency of the
Company in the Borough of Manhattan, City and State of New York, or elsewhere if
authorized by the  Company, upon surrender  and cancellation of  this bond,  and
thereupon  a  new bond  or bonds  of the  same  series and  of a  like aggregate
principal amount  will be  issued  to the  transferee  in exchange  therefor  as
provided  in the Indenture, upon payment of taxes or other governmental charges,
if any, that may be imposed in relation thereto.

    Bonds of this series are interchangeable  as to denominations in the  manner

    No charge shall be made by the Company for any exchange or transfer of bonds
of  the Series  due               , other  than for taxes  or other governmental

hereof   or  of  said   Indenture,  against  any   incorporator,  or  any  past,

                                  ARTICLE II.
              FORM AND EXECUTION OF BONDS OF SERIES DUE

    SECTION  2.01. There hereby is created,  for issuance under the Indenture, a
series of bonds designated Series due            , each of which shall bear  the
descriptive  title "First Mortgage Bond,  Series due              , and the form
thereof shall contain suitable provisions with respect to the matters  hereafter
specified  in this Section. The  bonds of said series  shall be substantially of
the tenor  and purport  hereinbefore recited.  The bonds  of said  series  shall
mature             , and shall be  issued as registered bonds without coupons in
denominations of  a multiple  of $1,000.  The bonds  of said  series shall  bear
interest at the rate of   % per annum payable semi-annually on         and
of each year, and the principal shall be payable at the office of the Trustee in
Chicago, Illinois, or at the option of the registered owner at the agency of the
Company in the Borough of Manhattan, City and State of New York, in lawful money
of the United States of America, and the interest shall be payable in like money
at  the option of the person entitled to  such interest either at said office of
the Trustee in Chicago, Illinois, or at the agency of the Company in the Borough
of Manhattan, City and State of New York.  Bonds of the Series due             ,
shall be dated as of the interest payment date next preceding the authentication
thereof by the Trustee except that (i) if any bond shall be authenticated before
             ,  it shall  be dated as  of               , unless  (iii) below is
applicable, (ii) if the  Company shall at  the time of  the authentication of  a
bond of the Series due           , be in default in the payment of interest upon
the  bonds of the Series due           , such bond shall be dated as of the date
of the beginning of  the period for  which such interest is  so in default,  and
(iii)  as long as there is no existing default in the payment of interest on the
bonds of the Series due            , if any bond of the Series  due            ,
shall  be authenticated after the close of business on any Record Date but on or
prior to the interest  payment date relating  to such Record  Date, it shall  be
dated as of such interest payment date.

    As  long as there is  no existing default in the  payment of interest on the
bonds of the Series due             , the person  in whose name any bond of  the
Series due           , is registered at the close of business on any Record Date
with  respect to  any interest  payment date  shall be  entitled to  receive the
interest payable on such interest  payment date notwithstanding any transfer  or
exchange  of such bond of the  Series due             , subsequent to the Record
Date and on or prior to such interest payment date, except as and to the  extent
the  Company shall default in  the payment of the  interest due on such interest
payment date, in which case such defaulted interest shall be paid to the  person
in whose name such bond of the Series due           , is registered on a Special
Record  Date  for the  payment of  such defaulted  interest to  be fixed  by the
Trustee, notice thereof shall be given to  the registered holder of any bond  of
the  Series due            , not less  than 10 days prior to such Special Record
Date, or may be  paid at any  time in any other  lawful manner not  inconsistent
with  the requirements  of any  securities exchange  on which  the bonds  of the
Series due            may be listed, and upon such notice as may be required  by
such exchange.

    The  term "Record Date" as used herein  with respect to any interest payment
date (         or       ) shall mean the              prior to such           or
      prior  to such      unless such            or      shall not be a business
day, in which event  "Record Date" shall mean  the next preceding business  day.
The  term "business day" as used herein shall mean any day other than a Saturday
or a Sunday or a day on which the offices of the Trustee in the City of Chicago,
Illinois, are closed pursuant to authorization of law.

    As used in this Section 2.01, the term "default in the payment of  interest"
means   failure  to  pay  interest  on  the  applicable  interest  payment  date
disregarding any period of grace permitted by the Indenture.
<PAGE>
                                       8

    The "Special Record  Date" as used  herein shall be  fixed in the  following
manner.  The  Company shall  notify  the Trustee  in  writing of  the  amount of
defaulted interest  proposed  to  be  paid  on  each  bond  of  the  Series  due
          ,  and the  date of  the proposed  payment, and  at the  same time the
Company shall deposit with the Trustee an amount of money equal to the aggregate
amount proposed to be paid in respect  of such defaulted interest or shall  make
arrangements  satisfactory to the Trustee for such  deposit prior to the date of
the proposed payment,  such money when  deposited to  be held in  trust for  the
benefit  of the persons entitled to such  defaulted interest as provided in this
Section 2.01. Thereupon  the Trustee  shall fix a  Special Record  Date for  the
payment of such defaulted interest which shall be not more than 15 nor less than
10  days prior to  the date of  the proposed payment  and not less  than 10 days
after the receipt  by the Trustee  of the  notice of the  proposed payment.  The
Trustee  shall promptly notify the  Company of such Special  Record Date and, in
the name and at the expense of  the Company, shall cause notice of the  proposed
payment  of such defaulted interest  and the Special Record  Date therefor to be
mailed, first class postage prepaid, to each  holder of the bonds of the  Series
due           , at his address as it appears in the bond register, not less than
10  days prior to  such Special Record  Date. Notice of  the proposed payment of
such defaulted interest and the Special Record Date therefor having been  mailed
as  aforesaid, such  defaulted interest  shall be paid  to the  persons in whose
names the bonds of the Series  due             , are registered on such  Special
Record  Date  and shall  not be  payable pursuant  to the  paragraph immediately
following in this Section 2.01.

    The Company may make payment of  any defaulted interest in any other  lawful
manner  not inconsistent  with the  requirements of  any securities  exchange on
which the bonds of  the Series due              , may be  listed, and upon  such
notice  as may be  required by such exchange,  if, after notice  is given by the
Company to the Trustee  of the proposed payment  pursuant to this Section  2.01,
such payment shall be deemed practicable by the Trustee.

    SECTION  2.02. The bonds of the Series due            , shall be redeemable,
other than for the Sinking Fund for bonds of that series provided for in Article
III hereof, at the option of the Company as a whole or in part on any date  upon
not  less than 30 days' previous  notice to be given in  the manner and with the
effect provided in Section 2 of Article X of the 1937 Indenture (except that, on
and after the  Effective Date,  such notice  shall be  given in  the manner  and
effect  provided  in Section  10.02 of  the Indenture)  at the  principal amount
thereof, with accrued  interest thereon  to the date  of redemption  and at  the
applicable  premium on  the principal amount  specified in  the tabulation below
under the heading  "Regular Redemption Premium,"  provided that no  bond of  the
Series  due           , shall be redeemed (other than through said Sinking Fund)
prior to           and the bonds of the Series due           , shall be  subject
to  call for redemption at par  for the Sinking Fund on  December 1 of each year
beginning    , upon  not less than 30 days' previous  notice to be given in  the
manner  and with the effect  provided in Article III hereof  and in Section 2 of
Article X of the 1937 Indenture (except  that, on and after the Effective  Date,
such notice shall be given in the manner and effect provided in Section 10.02 of
the  Indenture and in  Article III hereof)  at the principal  amount thereof and
accrued interest thereon to the date of redemption;

    The redemption prices of the bonds of the Series due           , need not be
specified in any temporary  bond of said series  if an appropriate reference  be
made in said temporary bond to the provision of this Section.

    [The  bonds of the Series due           are not redeemable prior to maturity
for any reason and are not subject to a sinking fund.]

    SECTION 2.03. The registered owner  of any bond or  bonds of the Series  due
          , at his option may surrender the same with other bonds of said series
at  the office  of the  Trustee in Chicago,  Illinois, or  at the  agency of the
Company in the Borough of Manhattan, City and State of New York, or elsewhere if
authorized by

                                       9

the Company, for cancellation, in exchange for other bonds of the said series of
higher or lower authorized  denominations, but of  the same aggregate  principal
amount, bearing interest from its date, and upon receipt of any payment required
under the provisions of Section 2.04 hereof. Thereupon the Company shall execute
and  deliver to the Trustee and the  Trustee shall authenticate and deliver such
other registered bonds to such  registered owner at its  office or at any  other
place specified as aforesaid.

    [Notwithstanding  the provisions  of Section  11 of  Article II  of the 1937
Indenture, the Company shall not be required to issue, transfer or exchange  any
bond  of the  Series due               , during a  period of ten  (10) days next
preceding any selection of bonds of the Series due            , to be  redeemed.
The Company shall not be required to transfer or exchange any bond of the Series
due              , called or  being called for redemption  in its entirety or to
transfer or exchange the called portion of a bond of the Series due            ,
which has been called for partial redemption.]

    SECTION  2.04. No charge  shall be made  by the Company  for any exchange or
transfer of bonds of the Series due             , other than for taxes or  other
governmental charges, if any, that may be imposed in relation thereto.

    SECTION  2.05. The bonds of the Series due            , shall be executed on
behalf of the Company  by the manual  signature of its President  or one of  its
Vice  Presidents  or with  the  facsimile signature  of  its President,  and its
corporate seal shall be thereunto affixed, or printed, lithographed, or engraved
thereon, in facsimile, and attested by the manual signature of its Secretary  or
one  of  its  Assistant  Secretaries  or with  the  facsimile  signature  of its
Secretary. In  case any  of the  officers who  shall have  signed any  bonds  or
attested  the seal thereon  or whose facsimile  signature shall be  borne by the
bonds shall cease to be such officers of the Company before the bonds so  signed
and sealed actually shall have been authenticated by the Trustee or delivered by
the Company, such bonds nevertheless may be issued, authenticated, and delivered
with  the same force and effect as though  the person or persons who signed such
bonds and attested the seal thereon or whose facsimile signature is borne by the
bonds had not ceased  to be such  officer or officers of  the Company. Any  bond
issuable hereunder may be signed or attested by manual or facsimile signature in
behalf  of the Company by such person as  at the actual date of the execution of
such bond shall be the  proper officer of the Company,  although at the date  of
such bond such person shall not have been an officer of the Company.

    SECTION  2.06. (a) Except as provided in  subsections (c) and (g) below, the
registered holder of all of the bonds of the Series due            shall be  The
Depository  Trust Company ("DTC") and the  bonds of the Series due             ,
shall be registered in the  name of Cede & Co.,  as nominee for DTC. Payment  of
principal  of[, premium, if  any,] and interest  on any bonds  of the Series due
          registered in the name of Cede & Co. shall be made by transfer of  New
York Federal or equivalent immediately available funds with respect to the bonds
of  the Series due            to the account  of Cede & Co. on each such payment
date for the bonds of the Series due           at the address indicated for Cede
& Co. in the bond register kept by the Trustee.

    (b) The bonds of the Series due            shall be initially issued in  the
form  of a  separate single  authenticated fully  registered certificate  in the
aggregate principal amount of  the bonds of  the Series due              .  Upon
initial  issuance, the ownership of such bonds of the Series due           shall
be registered in the  bond register kept by  the Trustee in the  name of Cede  &
Co.,  as nominee  of DTC.  The Trustee  and the  Company may  treat DTC  (or its
nominee) as the sole and exclusive registered holder of the bonds of the  Series
due                registered  in its name  for the  purposes of  payment of the
principal of[, premium, if  any,] and interest  on the bonds  of the Series  due
          ,  and  of giving  any notice  permitted  or required  to be  given to
holders under the Indenture,  except as provided in  Section 2.06(g) below;  and
neither  the Trustee  nor the  Company shall  be affected  by any  notice to the
contrary. Neither the Trustee nor the  Company shall have any responsibility  or
obligation  to  any of  DTC's participants  (each  a "Participant"),  any person
claiming a beneficial ownership in the bonds of the Series due           , under
or through DTC  or any  Participant (each a  "Beneficial Owner"),  or any  other
person  which is  not shown on  the bond  register maintained by  the Trustee as
being a  registered  holder,  with  respect  to  the  accuracy  of  any  records
maintained  by DTC or any Participant; the  payment of DTC or any Participant of
any amount in respect of  the principal of [, premium,  if any,] or interest  on
<PAGE>
                                       10

the  bonds of  the Series due               ;  any notice which  is permitted or
required to be given to registered holders  under the Indenture of bonds of  the
Series  due             ; or  any consent given or other  action taken by DTC as
bondholder. The Trustee  shall pay  all principal of  [, premium,  if any,]  and
interest on the bonds of the Series due           registered in the name of Cede
&  Co. only to or "upon  the order of" DTC (as that  term is used in the Uniform
Commercial Code as  adopted in Minnesota  and New York),  and all such  payments
shall  be  valid and  effective  to fully  satisfy  and discharge  the Company's
obligations with respect to the principal  of [, premium, if any,] and  interest
on  such bonds of the Series due             to the extent of the sum or sums so
paid. Except as otherwise provided in Sections 2.06(c) and (g) below, no  person
other  than  DTC shall  receive authenticated  bond certificates  evidencing the
obligation of the Company to make payments  of principal of and interest on  the
bonds  of the Series  due             .  Upon delivery by DTC  to the Trustee of
written notice to the effect that DTC has determined to substitute a new nominee
in place of  Cede & Co.,  and subject to  the provisions of  the Indenture  with
respect  to transfers of bonds, the word "Cede & Co." in this Supplemental Trust
Indenture shall refer to such new nominee of DTC.

    (c) If the  Company in  its discretion  determines that  it is  in the  best
interest of the Beneficial Owners that they be able to obtain bond certificates,
the  Company  may notify  DTC and  the  Trustee, whereupon  DTC will  notify the
Participants of  the availability  through  DTC of  bond certificates.  In  such
event,  the  Trustee  shall issue,  transfer  and exchange  bond  certificate as
requested by  DTC in  appropriate amounts  pursuant to  Article II  of the  1937
Indenture  prior to the Effective Date, Article  II of the Restated Indenture on
and after  the  Effective Date  and  Section  2.03 of  this  Supplemental  Trust
Indenture.  The Company shall pay all costs in connection with the production of
bond certificates if the Company makes  such a determination under this  Section
2.06(c). DTC may determine to discontinue providing its services with respect to
the  bonds of the Series due             at any time by giving written notice to
the Company and the  Trustee and discharging  its responsibilities with  respect
thereto under applicable law. Under such circumstances (if there is no successor
book-entry  depository), the Company and the  Trustee shall be obligated (at the
sole cost and expense of the Company) to deliver bond certificates as  described
in  this  Supplemental Trust  Indenture. If  bond  certificates are  issued, the
provisions of the Indenture shall apply to, among other things, the transfer and
exchange of such  certificates and  the method of  payment and  principal of  [,
premium,  if any,] and interest on  such certificates. Whenever DTC requests the
Company and the Trustee to  do so, the Company will  direct the Trustee (at  the
sole  cost  and  expense  of  the  Company)  to  cooperate  with  DTC  in taking
appropriate action after  reasonable notice (1)  to make available  one or  more
separate  certificates evidencing the bonds of the  Series due            to any
Participant or  (2) to  arrange for  another book-entry  depository to  maintain
custody  of certificates  evidencing the bonds  of the Series  due
registered in the name of Cede & Co. Any successor book-entry depository must be
a clearing  agency  registered  with  the  Securities  and  Exchange  Commission
pursuant  to Section 17A of  the Securities Exchange Act  of 1934 and must enter
into an  agreement with  the Company  and the  Trustee agreeing  to act  as  the
depository and clearing agency for the bonds of the Series due           (except
as  provided  in  Section  2.06(g)  below).  After  such  agreement  has  become
effective, DTC  shall present  the bonds  of the  Series due                 for
registration of transfer in accordance with Section 12 of Article II of the 1937
Indenture prior to the Effective Date and Section 2.12 of the Restated Indenture
on and after the Effective Date, and the Trustee shall register them in the name
of the successor book-entry depository or its nominee. If a successor book-entry
depository  has not  accepted such position  before the effective  date of DTC's
termination of its services, the book-entry system shall automatically terminate
and may not be reinstated without the  consent of all registered holders of  the
bonds of the Series due           .

    (d) Notwithstanding any other provision of this Supplemental Trust Indenture
to the contrary, so long as any bonds of the Series due           are registered
in  the name of Cede & Co., as nominee  of DTC, all payments with respect to the
principal of [, premium, if any,] and  interest on such Bonds of the Series  due
          and  all  notices  with  respect  to  such  bonds  of  the  Series due
          shall be  made and  given, respectively,  to DTC  as provided  in  the
representation  letter dated  as of  the date  of delivery  of the  bonds of the
Series due             among  DTC, the Company and  the Trustee. The Trustee  is
hereby  authorized and directed  to comply with all  terms of the representation
letter.

                                       11

    (e) In connection  with any  notice or  other communication  to be  provided
pursuant  to the Indenture  for the bonds of  the Series due              by the
Company or the Trustee with respect to  any consent or other action to be  taken
by the registered holders of the bonds of the Series due           , the Company
or the Trustee, as the case may be, shall seek to establish a record date to the
extent  permitted by the Indenture for such consent or other action and give DTC
notice of such record date not less  than fifteen (15) calendar days in  advance
of  such record date to  the extent possible. Such notice  to DTC shall be given
only when DTC is the sole registered holder.

    (f) NEITHER THE  COMPANY NOR  THE TRUSTEE  WILL HAVE  ANY RESPONSIBILITY  OR
OBLIGATIONS TO THE PARTICIPANTS OR THE BENEFICIAL OWNERS WITH RESPECT TO (1) THE
ACCURACY OF ANY RECORDS MAINTAINED BY DTC OR ANY PARTICIPANT; (2) THE PAYMENT BY
DTC  OR ANY PARTICIPANT OF ANY AMOUNT DUE  TO ANY BENEFICIAL OWNER IN RESPECT OF
THE PRINCIPAL OF [, PREMIUM, IF ANY,] OR INTEREST ON THE BONDS OF THE SERIES DUE
           ; (3) THE DELIVERY  BY DTC OR  ANY PARTICIPANT OF  ANY NOTICE TO  ANY
BENEFICIAL OWNER WHICH IS REQUIRED OR PERMITTED UNDER THE TERMS OF THE INDENTURE
TO BE GIVEN TO REGISTERED HOLDERS; (4) THE SELECTION OF THE BENEFICIAL OWNERS TO
RECEIVE  PAYMENT IN  THE EVENT  OF ANY  PARTIAL REDEMPTION  OF THE  BONDS OF THE
SERIES DUE            ; OR (5) ANY CONSENT GIVEN OR OTHER ACTION TAKEN BY DTC AS
A REGISTERED HOLDER.

    SO LONG AS CEDE &  CO. IS THE REGISTERED HOLDER  OF THE BONDS OF THE  SERIES
DUE            AS NOMINEE OF DTC, REFERENCES HEREIN TO REGISTERED HOLDERS OF THE
BONDS  OF THE SERIES DUE            SHALL MEAN CEDE & CO. AND SHALL NOT MEAN THE
BENEFICIAL OWNERS  OF THE  BONDS  OF THE  SERIES DUE                    NOR  DTC
PARTICIPANTS.

    (g)  The Company, in its sole discretion,  may terminate the services of DTC
with respect to the bonds of the Series due           if the Company  determines
that:  (i) DTC is unable  to discharge its responsibilities  with respect to the
bonds of the Series due             ; or (ii) a continuation of the  requirement
that all of the outstanding bonds of the Series due           be registered with
the registration books kept by the Trustee in the name of Cede & Co., as nominee
of DTC, is not in the best interest of the Beneficial Owners of the bonds of the
Series  due                . After  such event  and if  no substitute book-entry
depository is appointed by the Company,  bond certificates will be delivered  as
described in the Indenture.

    (h) Upon the termination of the services of DTC with respect to the bonds of
the Series due           pursuant to subsections (c) or (g) of this Section 2.06
after  which no substitute book-entry depository  is appointed, the bonds of the
Series due              shall be  registered in whatever  name or names  holders
transferring  or exchanging bonds of the Series due           shall designate in
accordance with the provisions of the Indenture.

                                 SINKING FUND.

    SECTION 3.01. (a) The  Company covenants that  it will on  the first day  of
October of each year commencing October 1,    , and continuing so long as any of
the bonds of the Series due           , are outstanding, pay or cause to be paid
to  the Trustee, for  and as a  fund for the  use and benefit  of the holders of
bonds of the Series due            , a sum in lawful money of the United  States
of  America equal to the amount required to  redeem on the first day of December
next following the date of such payment, in accordance with Section 3.02, 1%  of
the  highest aggregate  principal amount  of bonds  of that  series at  any time
outstanding. Such fund shall  be the Sinking  Fund for bonds  of the Series  due
          .  [The Company covenants that it  will meet its obligations under the
immediately preceding sentence for the year 199 solely and entirely through  the
application of permanent additions (or, if after the Effective Date, through the
application  of  an Amount  of Established  Permanent  Additions) in  the manner
hereinafter set forth in subdivision (c) of this Section 3.01.]

                                       12

    (b)  The delivery by the Company to  the Trustee of bonds of the Series  due
          ,  shall, for the purposes of satisfying the Sinking Fund for bonds of
that series, be  deemed equivalent  under this Section  to the  payment of  cash
equal  to the amount required to effect the redemption of the bonds so delivered
on the first day of December next  following such delivery. If any bonds of  the
Series  due                ,  have been  redeemed or  retired and  no bonds have
theretofore been  issued, cash  withdrawn,  or credit  taken  under any  of  the
provisions  of the Indenture on account of  the redemption or retirement of such
bonds, the Company may deduct from any payment for the Sinking Fund for bonds of
the Series due           , an amount equivalent to the amount required to effect
the redemption of a like amount of bonds of that series for the Sinking Fund for
bonds of the Series due           , on the first day of December next following,
provided that the  Company thereafter shall  not issue any  bonds, withdraw  any
cash, or take any credit under any of the provisions of the Indenture on account
of the redemption or retirement of such bonds and such bonds shall be cancelled.
For  the purpose of  this subdivision (b),  credit shall be  deemed to have been
taken for any bonds redeemed or retired if used as a reduction of the amount  of
cash  required  to be  deposited with  the  Trustee under  any provision  of the
Indenture or out of funds  pledged with the Trustee  under any provision of  the
Indenture,  other than funds deposited with the Trustee for the payment of bonds
upon maturity or upon redemption at the option of the Company.

    (c)  Prior to the Effective Date, the delivery by the Company to the Trustee
of a written  application of  the Company,  signed by  its President  or a  Vice
President,  to apply permanent additions acquired  or constructed by the Company
(which, under the provisions of Article V  of the 1937 Indenture, as amended  by
the Supplemental Trust Indenture thereto dated February 1, 1944, might otherwise
be  made the basis for the issuance of the bonds thereunder) to the Sinking Fund
provided for bonds of the Series due            for the purpose of such  Sinking
Fund  shall be deemed equivalent under this Section to the payment of cash equal
to the amount required  to effect the  redemption on the  first day of  December
next  following, of bonds of the  Series due             , in an amount equal to
66 2/3% of the cost or fair value, whichever is less, of the permanent additions
so applied, after making the deductions provided  for in Section 3 of Article  V
of  the 1937 Indenture to a date not more than 90 days preceding the date of the
delivery to the Trustee of such application, on account of property removed from
service or  abandoned and  not replaced  or offset;  provided that  the  Company
thereafter  shall not  issue any  bonds, withdraw any  cash, or  take any credit
under any of the  provisions of the  Indenture upon the  basis of the  permanent
additions  so applied. Prior to the Effective  Date, such an application in each
case  shall  be   accompanied  by  the   resolutions,  certificates,   opinions,
instruments,  and other papers provided  for in Subsection (B)  of Section 10 of
Article XI of the 1937 Indenture, as amended by the Supplemental Trust Indenture
thereto dated February 1, 1944, in case  of withdrawal of cash from the  Release
Fund with such omissions or variations therefrom or insertions therein as may be
appropriate  in the light of  the purpose for which they  are used. On and after
the Effective Date,  the delivery by  the Company  to the Trustee  of a  written
application of the Company signed by its President or a Vice President, to apply
an Amount of Established Permanent Additions established as provided in Sections
5.05  and 5.06 of  the Indenture (which  has not been  applied previously to any
other purpose specified in  the Indenture) to the  Sinking Fund provided for  in
this  Article III, for purposes of said  Sinking Fund shall be deemed equivalent
under this Section to the payment of cash equal to the amount required to effect
the redemption  on the  first day  of December  next following,  of a  principal
amount  of Bonds of  this Series equal to  66 2/3% of  the Amount of Established
Permanent Additions so applied.

    SECTION 3.02. (a) As soon as may be, after each payment to the Sinking  Fund
provided  for bonds of the Series due            , is so made, the Trustee shall
apply the moneys in such Sinking Fund to the purchase of bonds of the Series due
          , in the open  market, at the lowest  price or prices obtainable,  but
not  to exceed the price  at which the bonds of  such series are then redeemable
for the Sinking Fund as herein provided. If within 20 days after each payment to
the Sinking Fund, the Trustee  shall be unable to  purchase bonds of the  Series
due            ,  as aforesaid, sufficient to reduce the amount of money held in
the Sinking Fund to less than $10,000, the Trustee shall apply the Sinking  Fund
for  bonds of  the Series  due                ,  or the  balance thereof  to the
redemption, on the first day of December next following the receipt of such cash
by the Trustee, of bonds  of such series at  the sinking fund redemption  prices
provided for in Section 2.02 of this Supplemental Trust Indenture.

                                       13

    (b)   The  particular bonds  to be  redeemed for  the Sinking  Fund shall be
selected by the Trustee by  lot, in such manner as  it shall deem proper in  its
discretion,  from the  distinctive numbers  borne by  or assigned  to registered
bonds of the Series due           , as herein provided. For each registered bond
of a denomination in  excess of $1,000, the  Trustee shall assign a  distinctive
number of each $1,000 of the principal amount thereof. Registered bonds shall be
deemed  to have been drawn by lot if and to the extent that the numbers borne by
or assigned thereto  as above provided  are selected as  aforesaid. The  Trustee
shall  notify the Company in writing of  the distinctive numbers of the bonds of
the Series due            , to be redeemed for the Sinking Fund. The Trustee  is
authorized  and empowered hereby to  give or cause to be  given on behalf of the
Company the notice required by Section 2.02 hereof in order to redeem bonds  for
Sinking Fund purposes.

    (c)  On and after the commencement of notice of redemption of bonds pursuant
to  this Section, the Trustee  shall (subject to the  provisions of Section 5 of
Article XX  of  the 1937  Indenture  prior to  the  Effective Date  and  to  the
provisions  of Section 20.03 of  the Indenture on and  after the Effective Date)
hold the moneys necessary to  redeem the bonds so to  be redeemed as a  separate
trust  fund for the  account of the  respective holders thereof  and such moneys
shall be  paid to  them respectively  upon presentation  and surrender  of  such
bonds;  and after the redemption date, such  bonds shall cease to be entitled to
the lien, benefits, or security of the Indenture, and as respects the  Company's
liability thereon such bonds and all claims for interest thereon shall be deemed
to  have been paid; this Section being in all respects subject to the provisions
of Section 5 of Article XX of the 1937 Indenture prior to the Effective Date and
to the provisions of Section 20.03 of  the Indenture on and after the  Effective
Date,  except that, on and  after commencement of notice  of redemption of bonds
pursuant to this Section 3.02, such bonds shall be deemed to have been  redeemed
from  the holder  or holders  thereof and  paid for  the purpose  of release and
satisfaction of the Indenture.

    (d)  If  there shall  be drawn  for redemption  a portion  of the  principal
amount  less than the  entire amount of  any registered bond,  the Company shall
execute and the  Trustee shall authenticate  and deliver without  charge to  the
holder thereof registered bonds of the Series due           , for the unredeemed
balance of such registered bond.

    SECTION  3.03.  All bonds  delivered  to the  Trustee  in lieu  of  cash, or
purchased by  the Trustee,  or redeemed  by  operation of  the Sinking  Fund  in
accordance  with  the provisions  of  this Article,  shall  be cancelled  by the
Trustee. Bonds so cancelled shall not be reissued and no additional bonds  shall
be  authenticated and  delivered in substitution  therefor or on  account of the
retirement thereof and  no credit  shall be taken  or cash  withdrawn under  the
provisions of the Indenture on the basis thereof.

                                  ARTICLE IV.
                      APPOINTMENT OF AUTHENTICATING AGENT.

    SECTION  4.01. The Trustee  shall, if requested  in writing so  to do by the
Company, promptly  appoint an  agent or  agents of  the Trustee  who shall  have
authority  to authenticate registered bonds of the Series due           , in the
name and on  behalf of the  Trustee. Such  appointment by the  Trustee shall  be
evidenced  by a certificate of a vice-president  of the Trustee delivered to the
Company prior to the effectiveness of such appointment.

    SECTION 4.02. (a)  Any such authenticating agent shall be acceptable to  the
Company  and at all  times shall be  a corporation which  is organized and doing
business under the  laws of the  United States  or of any  State, is  authorized
under  such laws  to act  as authenticating  agent, has  a combined  capital and
surplus of at least $10,000,000, and is subject to supervision or examination by
Federal or State authority. If  such corporation publishes reports of  condition
at  least annually,  pursuant to  law or  to the  requirements of  the aforesaid
supervising or examining authority, then for  the purposes of this Section  4.02
the  combined capital and surplus of such  corporation shall be deemed to be its
combined capital and surplus as set forth in its most recent report of condition
so published.

    (b)  Any corporation  into which any authenticating  agent may be merged  or
converted  or with  which it may  be consolidated, or  any corporation resulting
from   any    merger,    conversion,    or   consolidation    to    which    any
<PAGE>
                                       14

authenticating  agent shall  be a  party, or  any corporation  succeeding to the
corporate agency business of any authenticating agent, shall continue to be  the
authenticating agent without the execution or filing of any paper or any further
act on the part of the Trustee or the authenticating agent.

    (c)   Any  authenticating agent  at any  time may  resign by  giving written
notice of resignation to the Trustee and to the Company. The Trustee may at  any
time,  and upon written request  of the Company to  the Trustee shall, terminate
the agency of any authenticating agent  by giving written notice of  termination
to such authenticating agent and to the Company. Upon receiving such a notice of
resignation   or  upon  such  a  termination,  or   in  case  at  any  time  any
authenticating  agent  shall  cease  to  be  eligible  in  accordance  with  the
provisions  of this  Section 4.02,  the Trustee,  unless otherwise  requested in
writing by the Company, promptly shall appoint a successor authenticating agent,
which shall be  acceptable to  the Company. Any  successor authenticating  agent
upon  acceptance of its  appointment hereunder shall become  vested with all the
rights, powers, duties, and responsibilities of its predecessor hereunder,  with
like  effect as if originally named.  No successor authenticating agent shall be
appointed unless eligible under the provisions of this Section 4.02.

    (d)  The  Trustee agrees to  pay to any  authenticating agent, appointed  in
accordance with the provisions of this Section 4.02, reasonable compensation for
its  services,  and the  Trustee shall  be  entitled to  be reimbursed  for such
payments.

    SECTION 4.03. If  an appointment is  made pursuant to  this Article IV,  the
registered  bonds of the Series due            , shall have endorsed thereon, in
addition to the Trustee's Certificate, an alternate Trustee's Certificate in the
following form:

    This bond is one of the bonds of the Series designated thereon, described in
the within-mentioned Indenture.

                                          By
                                                  Authenticating Agent,

     Re:  $300,000,000 principal amount of
          First Mortgage Bonds of Northern
          States Power Company, a Minnesota
          corporation

Gentlemen:

I am participating in the proceedings incident to the issuance
and sale by Northern States Power Company, a Minnesota
corporation (the Company) of up to $300,000,000 principal amount
of First Mortgage Bonds, (the New Bonds).  I have examined all
statutes, records, instruments, and documents which I have
deemed necessary to examine for the purposes of this opinion.

Based upon the foregoing and upon my general familiarity with
the Company and its affairs, I am of the opinion that:

     1.   The Company was incorporated and is now a legal
          existing corporation under the laws of the state of
          Minnesota; has corporate power, right and authority to
          do business and to own property in the States of
          Minnesota, North Dakota and South Dakota in the manner
          and as set forth in the Registration Statement, Form
          S-3, to which this opinion is an exhibit; and has
          corporate power, right, and authority to create,
          issue, and sell the New Bonds.

     2.   When and if (a) the above mentioned Registration
          Statement has become effective pursuant to the
          provisions of the Securities Act of 1933, as amended;
          (b) the Minnesota Public Utilities Commission has
          issued its order approving Capital Structure which
          permits the Company to issue the New Bonds; (c) the
          Supplemental Trust Indenture relating to the New Bonds
          from the Company to Harris Trust and Savings Bank,
          Trustee, has been duly authorized, executed,
          delivered, filed and recorded as required by law; and
          (d) the New Bonds have been duly authorized, executed,
          authenticated, and delivered and the consideration for
          the New Bonds has been received by the Company, all in
          the manner contemplated by the said Registration
          Statement, the New Bonds will be legally issued and
          binding obligations of the Company and entitled to the
          benefits and security of the Company's Trust
          Indenture, dated February 1, 1937, as supplemented.

     3.   The statements made in the above mentioned
          Registration Statement and related Prospectus,
          purporting to be made or based upon the opinion of
          counsel, correctly set forth my opinion upon said
          matters.

Respectfully submitted,
