    Northern  States Power Company  (the "Company"), incorporated  in 1901 under
the laws of Wisconsin as the La Crosse Gas and Electric Company, is an operating
public utility company with executive offices  at 100 North Barstow Street,  Eau
Claire,   Wisconsin  54702-0008   (phone:  715-839-2416).   The  Company   is  a
wholly-owned  subsidiary  of   Northern  States  Power   Company,  a   Minnesota
corporation (the "Minnesota Company").
    
 
   
    The  Company is engaged in the  production, transmission and distribution of
electricity  to  approximately   202,000  retail   customers  in   an  area   of
approximately  18,900 square  miles in northwestern  Wisconsin, to approximately
9,200 electric retail customers in an area of approximately 300 square miles  in
the  western portion  of the  Upper Peninsula of  Michigan, and  to 10 wholesale
customers in  the  same  general  area.  The Company  is  also  engaged  in  the
distribution  and  sale  of  natural  gas  in  the  same  service  territory  to
approximately 67,000 customers in Wisconsin and 4,800 customers in Michigan.  In
Wisconsin,  some of the  larger communities the Company  provides natural gas to
are Eau Claire, Chippewa Falls, La Crosse, Hudson, Menomonie and Ashland. In the
Upper Peninsula of Michigan the  largest community the Company provides  natural
gas  to  is Ironwood.  In  1995, the  Company derived  83  percent of  its total
operating revenues  from electric  utility operations  and 17  percent from  gas
utility operations.
    
 
                                PROPOSED MERGER
 
   
    The Minnesota Company, Wisconsin Energy Corporation, a Wisconsin corporation
("WEC"),   Northern  Power   Wisconsin  Corp.,   a  Wisconsin   corporation  and
wholly-owned subsidiary of the Minnesota Company, and WEC Sub Corp., a Wisconsin
corporation and wholly-owned subsidiary of  WEC, 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  the Minnesota  Company 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 Minnesota 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 goal of the
Minnesota  Company  and  WEC  is  to  receive  approvals  from  all   regulatory
authorities  by the end  of 1996, however, some  regulatory authorities have not
established a timetable for their decisions. Therefore, timing of the receipt of
the approvals necessary to complete the Transaction is not known at this time.
    
 
   
    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  Minnesota Company (which,  for regulatory  reasons,
will  reincorporate  in  Wisconsin)  and of  WEC's  present  utility subsidiary,
Wisconsin Electric  Power Company  ("WEPCO") which  will be  renamed  "Wisconsin
Energy  Company." It is anticipated that,  following the Transaction, except for
certain gas distribution properties serving  the cities of LaCrosse and  Hudson,
Wisconsin that will be transferred to the Minnesota Company, the Company will be
merged into Wisconsin Energy Company (the "Company Merger").
    
 
   
    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
1995 Form 10-K. Additional information concerning the Transaction and the Merger
Agreement is included in the 1995 Form 10-K.
    
 
   
    Both  the Company and WEPCO recognize that the divestiture of their existing
gas operations  is  a  possibility  under the  new  registered  holding  company
structure, but will seek approval from the
    
 
                                       3
<PAGE>
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  Company Merger,  the  New Bonds  and the
Company's  other  outstanding  first  mortgage  bonds  will  be  obligations  of
Wisconsin  Energy Company, as a subsidiary of  Primergy, and will continue to be
secured by the Indenture  as described in this  Prospectus. See "DESCRIPTION  OF
NEW BONDS -- Security for New Bonds." However, as described above, the New Bonds
will  not be an obligation of Primergy  or any other subsidiary of Primergy. The
1995 Form 10-K  includes pro  forma financial information  for Wisconsin  Energy
Company following the Company Merger.
    
 
                                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  the  Company's  continuing  construction  program.  Short-term
borrowings of the  Company aggregated $35.8  million as of  March 31, 1996.  The
specific  allocation of the proceeds of a particular series of the Offered Bonds
will be described in the Prospectus Supplement.
    
 
                       CONSTRUCTION PROGRAM AND FINANCING
 
   
    The Company's construction  program for 1996-2000,  including allowance  for
funds used during construction, is presently estimated to be $303 million (1996:
$54  million; 1997: $60 million; 1998: $68 million; 1999: $64 million; and 2000:
$57 million). Of these construction expenditures, approximately 88% are expected
to be  provided  by  internally  generated funds.  The  foregoing  estimates  of
construction  expenditures  and internally  generated  funds may  be  subject to
substantial  changes  due  to  unforeseen  factors,  such  as  changed  economic
conditions,  competitive conditions,  technological innovations,  new government
regulations, changed tax laws and rate  regulation. In addition, if the  Company
Merger is completed as expected, the Company's construction program for 1997 and
future  years  will  be  incorporated into  Wisconsin  Energy  Company's overall
construction program.

    For purposes  of computing  the  ratio of  earnings  to fixed  charges,  (i)
earnings  consist of income from  continuing operations before accounting change
plus fixed charges, federal  and state income taxes,  deferred income taxes  and
investment  tax credits; 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.

                            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 April 1,
1947 (the "1947 Indenture") as supplemented by 12 supplemental trust  indentures
(collectively,  the  "Supplemental  Indentures,"), a  Supplemental  and Restated
Trust Indenture  dated  March 1,  1991  (the  "Restated Indenture")  and  a  new
supplemental trust indenture for such series of New Bonds (the "New Supplemental
Indenture")  all from  the Company to  Firstar Trust Company  (formerly known as
First Wisconsin Trust Company), as trustee (the "Trustee"). The 1947  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,  three series  of Bonds  in an aggregate
principal amount of $194,635,000 currently are outstanding under the  Indenture.
Copies  of  the  1947  Indenture,  the  Supplemental  Indentures,  the  Restated
Indenture and the form of the  New Supplemental Indenture are filed as  Exhibits
4.01A  to 4.01O  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  1947 Indenture, the
Supplemental  Indentures,  the  Restated  Indenture  and  the  New  Supplemental
Indenture which are incorporated herein by this reference.
    
 
    The  Restated  Indenture  amends and  restates  the 1947  Indenture  and the
Supplemental Indentures. The Restated  Indenture became effective and  operative
on October 1, 1993.
 
    References  are made to specific Article and Section numbers of the Restated
Indenture and  the  New Supplemental  Indenture.  Unless the  context  indicates
otherwise,  words  or  phrases defined  in  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 Milwaukee,  Wisconsin, at
Firstar Trust Company. 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
    
 
                                       5
<PAGE>
   
unlikely  in any transaction that would result in the Company, or a successor to
the Company,  including  Wisconsin Energy  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  by the Indenture, which constitutes a first mortgage lien, subject only
to Permitted Encumbrances, upon all real  and fixed properties now owned by  the
Company  (except as otherwise stated  in this paragraph) for  the equal pro rata
security of all Bonds issued or to be issued under the Indenture, subject to the
provisions relating to any sinking fund or similar fund for the benefit of Bonds
of any particular  series. There  are excepted from  the Lien  of the  Indenture
securities, cash, contracts, receivables, motor vehicles, merchandise, equipment
and  supplies, and certain  non-utility real property.  (Granting Clauses of the
Restated Indenture.) The  Indenture contains  provisions for  subjecting to  the
lien  thereof  (subject  to  the  limitations in  Article  XVI  in  the  case of
consolidation or merger) all property acquired by the Company after the date  of
the  1947 Indenture other than  property of the kind  mentioned in the preceding
sentence. 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 flowage  rights not  presently exercised  or titles  to
rights-of-way  for transmission and distribution  facilities, as counsel for the
Company believes  that the  expense  of examination  would  exceed the  cost  of
acquiring,  by  condemnation or  purchase, any  easements or  rights-of-way held
under defective title. The Company has the power of eminent domain in the states
in which it operates.
    
 
    Permitted Encumbrances  include (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 property for the purpose for which
it is held by the Company and which will not have 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.)
 
   
    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
19.02(e) of the Restated Indenture.)
    
 
   
    The  Indenture is not a lien on the properties of the Minnesota Company. The
Lien of the  Indenture will continue  to apply only  to property and  franchises
owned  by  the  Company prior  to  the  Company Merger,  and  to  any additions,
extensions and repairs  to such properties  acquired or made  after the  Company
Merger,  and will not apply to any property  owned by WEPCO prior to the Company
    
 
                                       6
<PAGE>
   
Merger. It  is expected  that  following the  Company Merger,  Wisconsin  Energy
Company's  outstanding indebtedness will include  first mortgage bonds that were
previously issued  by the  Company,  WEPCO, Wisconsin  Natural Gas  Company  and
Wisconsin  Southern Gas Company  under separate trust  indentures. See "PROPOSED
MERGER" and "RATIO OF EARNINGS  TO FIXED CHARGES." It  is not expected that  any
additional  Bonds  will  be issued  under  the Indenture  following  the Company
Merger.
    
 
SINKING FUND PROVISIONS
 
   
    The sinking fund redemption  provision, if any, for  each series of the  New
Bonds will be set forth in the Prospectus Supplement. As an annual sinking fund,
the  Company  covenants to  pay to  the Trustee  annually on  April 1  an amount
sufficient to redeem, on the following June  1, for sinking fund purposes 1%  of
the  highest amount at any time outstanding of  Bonds of the Series due April 1,
2021 and the Bonds of the Series due March 1, 2023. Sinking fund payments may be
offset at the option of the Company by (a) retirement or delivery to the Trustee
of Bonds  of  the  series for  which  the  sinking fund  is  applicable  or  (b)
application  of Amounts of Established Permanent  Additions equal to 150% of the
principal amount of Bonds which would otherwise be required to be retired by the
sinking fund. (Sections 5.04(vi), 5.07 and 13.01(c) of the Restated  Indenture.)
The  Trustee  is  required  to  apply sinking  fund  money  to  the  purchase or
redemption of Bonds of the series for which such funds are applicable.  (Article
XIII of the Restated Indenture.)
    
 
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 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)  retirement 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 1990,  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.)
 
   
    The Company has covenanted  to maintain its  properties in adequate  repair,
working order and condition. (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) 66 2/3% of the Cost or Fair Value, whichever is less, of  Permanent
Additions,  after making the required deductions  on account of Retired Property
(Article V of  the Restated  Indenture); (b) retired  Bonds that  have not  been
otherwise  used under the Indenture (Article  VI of the Restated 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 Restated Indenture.)
    
 
   
    The New Bonds will be issued under clauses (a) and/or (b) above. At December
31, 1995 the  amount of net  Permanent Additions available  for the issuance  of
Bonds  exceeded  $113 million,  of which  $97.6  million could  be used  for the
authentication of $65 million principal amount of the New Bonds.  As of December
31, 1995, $81 million of retired Bonds were available for the authentication  of
up to $81 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, and any
obligations secured by  Prior Liens  and any indebtedness  secured by  Permitted
Encumbrances.  The calculation of Earnings  Applicable to Bond Interest includes
all non-utility revenues of the Company. (Sections 1.03, 5.03, 6.02 and 7.01  of
the Restated Indenture.)
    
 
                                       7
<PAGE>
    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; fractional and undivided
property  interests of  the Company;  property used  for providing  telephone or
other   communications   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.)
 
   
    Earnings  Applicable to Bond  Interest for the  twelve months ended December
31, 1995,  would be  4.8 times  the annual  interest requirements  on the  Bonds
assuming  the issuance  of the New  Bonds at  an assumed interest  rate of 8.0%.
Additional Bonds may vary from the Offered Bonds as to maturity, interest  rate,
redemption  prices, sinking fund  and in certain other  respects. (Article II of
the Restated Indenture.)
    
 
DIVIDENDS ON COMMON STOCK
 
   
    The Indenture does not  restrict the Company's payment  of dividends on  its
common stock.
    
 
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
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 Restated Indenture.)
 
    Under the Indenture, (a) the Company may sell or otherwise dispose of,  free
of  the Lien of the Indenture, all  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 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.)
 
   
    Any  of the mortgaged and pledged property  may be released from the Lien of
the Indenture without  depositing the proceeds  from the sale  of such  property
with  the  Trustee, if  after  such release,  the  Fair Value  of  the remaining
mortgaged and pledged property of the character of Permanent Additions equals or
exceeds a  sum  equal  to  150%  of the  aggregate  principal  amount  of  Bonds
Outstanding.  (Section 11.03(k) of the Restated Indenture.) 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,  including  all  or  a  portion  of  the  Company's  electric
generation,  transmission  or  distribution  assets,  or  its  gas  storage  and
distribution assets, without  depositing cash  or property with  the Trustee  or
obtaining the consent of the bondholders.
    
 
   
REDEMPTION GENERALLY
    
 
   
    Moneys  on deposit in  the Maintenance Fund  and the Release  Fund under the
Indenture may be used for the purchase or redemption of Bonds, provided that the
Company does not have the power to use  any such moneys to redeem any Bond  that
is not otherwise redeemable or to redeem any Bond at a price less than the price
at which such Bond could be redeemed pursuant to its terms.
    
 
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 66 2/3% 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 XIX of the Restated Indenture.)
 
                                       8
<PAGE>
CONCERNING THE TRUSTEE
 
   
    In  case of a Completed Default the Trustee may, and upon written request of
the holders of  a majority  in principal amount  of the  Bonds then  Outstanding
shall,  declare the  principal of  all Bonds  then Outstanding  and the interest
accrued thereon to be due and payable immediately, and the same shall become due
and payable subject to  the right of  the holders of  the majority in  principal
amount  of the  Bonds then  Outstanding upon  certain conditions  to rescind and
annul such declaration. The  Indenture provides in substance  that no holder  of
any  Bond shall have  any right to  institute any suit,  action or proceeding in
equity or at law for the foreclosure of the Indenture or for the appointment  of
a  receiver or  for any  other remedy thereunder  unless such  holder shall have
previously given to the Trustee written  notice of default, nor unless also  the
holders of 25% in principal amount of the Bonds then Outstanding shall have made
written  request to the Trustee to exercise  the powers granted by the Indenture
but the right of action of holders of Bonds to enforce payment of the  principal
or  interest shall not be impaired. As  a condition precedent to certain actions
by the Trustee in the enforcement of  the Lien of the Indenture and  institution
of  action  on the  Bonds, the  Trustee may  require adequate  indemnity against
costs, expenses and  liabilities to  be incurred  thereby. (Article  XIV of  the
Restated Indenture.)
    
 
    The  Company utilizes some of the  commercial banking services offered by an
affiliate of the Trustee.
 
DEFAULTS
 
   
    The following is a summary of  events defined in the Indenture as  Completed
Defaults:  (a) default in the payment of principal of or premium, if any, on any
Bond when due and payable, (b) default  continued for 30 days in the payment  of
interest  on any  Bond; (c) default  continued for  60 days in  any sinking fund
payment; (d) default in the covenants of the Company with respect to bankruptcy,
insolvency, assignment or  receivership, or  (e) default continued  for 60  days
after  notice to the  Company from the  Trustee in the  performance of any other
covenant, agreement or condition contained  in the Indenture. (Section 14.01  of
the Restated Indenture.)
    
 
    The  Trustee is required  to give notice  to bondholders (1)  within 90 days
after the occurrence of a  Default known to the  Trustee within such period,  or
(2)  if the Trustee is  unaware of a Default  during such period, promptly after
the Trustee knows  of such Default,  unless such Default  shall have been  cured
before the giving of such notice; provided that, except in the case of a Default
resulting  from the failure to make any payment of principal of, or interest on,
any Bonds or to  make any sinking  fund payment, the  Trustee may withhold  such
notice upon determination in good faith by the board of directors, the executive
committee  or a trust committee of  directors and/or responsible officers of the
Trustee that  the  withholding  of  such  notice  is  in  the  interest  of  the
bondholders. (Article XVII of the Restated Indenture.)
 
   
    If  the Trustee recovers any moneys  following a Completed Default, all such
moneys shall be applied  in the following  order: (i) to  the payment of  taxes,
assessments  or Prior Liens and all costs and expenses, including the payment of
the fees, expenses, liabilities  and advances incurred or  made by the  Trustee,
(ii) to the payment in full of the amounts then due and unpaid for principal and
interest upon the Bonds then Outstanding, and in the case such proceeds shall be
insufficient  to pay in full the amounts so  due and unpaid, then to the payment
thereof ratably, with interest on overdue  principal and interest, and (iii)  to
the  Company,  its  successors  or  assigns.  (Section  14.11  of  the  Restated
Indenture.)
    
 
    The Company is required to file with the Trustee such information, documents
and reports with respect  to compliance by the  Company with the conditions  and
covenants  of the Indenture as  may be required by  the rules and regulations of
the Commission  including  a certificate,  furnished  not less  frequently  than
annually,  as  to  the  Company's  compliance with  all  of  the  conditions and
covenants under the Indenture. (Section 8.18 of the Restated Indenture.)
 
                                       9
<PAGE>
GENERAL
 
   
    Whenever all indebtedness secured by the Indenture shall have been paid,  or
adequate  provision  therefor  made,  the Trustee  shall,  upon  request  of the
Company, cancel and discharge the Lien  of the Indenture. (Article XVIII of  the
Restated  Indenture.)  The Company may  deposit with the Trustee any combination
of cash or Governmental Obligations in order  to provide for the payment of  any
series  or  all of  the Bonds  Outstanding.  Such a  deposit could  constitute a
taxable event as  to the holders  of such bonds,  creating possible adverse  tax
consequences.  The Indenture also provides that the Company shall furnish to the
Trustee Officers' Certificates, certificates of an Engineer, Appraiser or  other
expert  and, in certain cases, Accountants'  Certificates in connection with the
authentication of Bonds, the release or release and substitution of property and
certain other matters, and Opinions of Counsel  as to the Lien of the  Indenture
and  certain other matters. (Articles  IV, V, VI, VII,  XI and XVIII and Section
21.08 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 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
 
                                       10

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 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 purposes  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 Act 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 Act and  will
be governed by the final adjudication of such issue.

    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

    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 their 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 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
 
                                       5
<PAGE>
    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.
 
        (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  the
    Representatives), 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

costs, taxes and expenses incident to the issue and delivery of the Bonds to the

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  representatives 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 John  P. Moore, Jr., General  Counsel and 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.
 
                                       6
<PAGE>
        (d) The Company shall have furnished to the Underwriters the opinion  of
    Loomis,  Ewert, Ederer, Parsley,  Davis & Gotting,  special Michigan counsel
    for the Company, dated the Closing Date, to the effect that:
 
           (i) the Company is duly authorized as a foreign corporation under the
       laws of  the  State  of  Michigan and  has  corporate  power,  right  and
       authority  to do business in  the State of Michigan  in the manner as set
       forth in the Prospectus to the  extent it is authorized to transact  such
       business  in the State of Wisconsin, and  to own property in the State of
       Michigan in the manner set forth in the Prospectus;
 
           (ii) the Indenture is in proper  form, conforming to the laws of  the
       State  of Michigan,  to give  and create  the lien  which it  purports to
       create as to the property therein  described and located in the State  of
       Michigan  assuming that the Company holds marketable record title to such
       property, except that the lien of  the Indenture may not be effective  as
       to  a  bona  fide purchaser  (including  a  mortgagee) for  value  of any
       after-acquired real  property from  the  Company, unless  a  supplemental
       indenture  to the Trustee specifically  describing such property has been
       duly recorded prior to such purchase  or the effective date of  recording
       of  such other lien; and  the Indenture is duly  and properly recorded or
       filed in all places in Michigan  necessary to effectuate the lien of  the
       Indenture as to said property;
 
          (iii)  the Company  has all  necessary power  under Michigan statutory
       provisions and has all necessary franchises to use its operating electric
       and gas properties  in Michigan,  except that no  determination has  been
       made  whether the Company or its Michigan predecessor has secured permits
       and approvals, if any, required by  the Wetlands Protection Act, 1979  PA
       302, and except that the Company does not have electric franchises in the
       cities  of Ironwood, Bessemer and Wakefield,  County of Gogebic, State of
       Michigan. However, counsel for the Company, Aberg, Bell, Blake & Metzner,
       rendered an opinion on April 19, 1968, that municipal franchises were not
       required for the cities of Ironwood and Bessemer; and
 
          (iv) No approval, authorization, consent, certificate or order of  any
       Michigan  commission or  regulatory authority  is required  in connection
       with  the  issuance  and  sale  of  the  Bonds  by  the  Company  to  the
       Underwriters  as provided  in this  Agreement except  as may  be required
       under state securities laws.
 
        (e)  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 paragraph (a) and (i) 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  representatives  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
 
           (ii) there has been  no material adverse change  in the condition  of
       the  Company,  financial or  otherwise, or  in  the earnings,  affairs or
       business prospects of the Company, whether or not arising in the ordinary
       course  of  business,  from  that  set  forth  or  contemplated  by   the
       Registration Statement or Prospectus Supplement.
 
        (f)  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  financial statements and  financial
    statement  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
 
                                       7
<PAGE>
    with the  applicable accounting  requirements of  the Exchange  Act and  the
    published  rules  and  regulations  thereunder,  (iii)  they  have performed
    limited procedures, not constituting  an audit, including  a reading of  the
    latest  available interim financial statements of  the Company, a reading of
    the minutes of meetings of the  Board of Directors, committees thereof,  and
    of  the  Shareholders, of  the Company  since  the date  of the  most recent
    audited financial statements  included or incorporated  by reference in  the
    Prospectus,  inquiries of officials of the Company 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  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  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 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, or  net income,  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 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.
 
        (g)  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 (f) 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.
 
        (h)  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
 
                                       8
<PAGE>
    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.
 
        (i)  (i) The  Company shall  not 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, the  Company shall  not  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 there shall  not have been  any change in the
    capital stock  or  long-term debt  of  the Company  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 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 Representatives 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.
 
        (j)    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.
 
        (k) 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 facsimile transmission 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 Representatives, threatened.
 
        (b)  The orders  of the Public  Service Commission of  Wisconsin and the
    Michigan Public Service Commission referred to in paragraph (l) of Section 1
    shall be in full force and effect.
 
    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
<PAGE>
    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) 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 reasonably  incurred
by  them in connection with investing or defending any such loss, claim, damage,
liability or action; PROVIDED that the Company will not be liability 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)  form 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
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 the  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 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
 
                                       10
<PAGE>
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 to  to assume the defense of  such action and approval by
the indemnifying party of counsel, the indemnifying party will not be liable  to
such  indemnifying 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 indemnifying 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 indemnifying parties under paragraphs
(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
indemnifying party to represent the indemnifying 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 indemnifying 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  the Section 9 is unavailable to
or insufficient to hold harmless an indemnified party under paragraph (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  hand 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  paragraph (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 paragraph (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 paragraph  (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 paragraph  (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 paragraph (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  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  paragraph
(d)  to contribute  are several in  proportion to  their respective underwriting
obligations and not joint.
 
                                       11
<PAGE>
    (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  "Unpurchased Bonds"),  the  Representatives may  in  their
discretion arrange for themselves or any 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. If 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,  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  paragraph  (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   Bond  of   a  defaulting   Underwriter  or   Underwriters  by  the
Representatives and  the  Company  as  provided  in  paragraph  (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  paragraph (b)  above, of  if the  company shall  not exercise  the  right
described  in  paragraph (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, Wisconsin  or
New  York State authorities, (iii)  if trading in any  securities of the Company
shall have been suspended or halted, or (iv) if
 
                                       12
<PAGE>
there shall have occurred any  outbreak or exclamation 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

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.

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

                     FORM OF OPINION OF JOHN P. MOORE, JR.
      RE: $  ,000,000 PRINCIPAL AMOUNT OF FIRST MORTGAGE BONDS, SERIES DUE
                                           ,    %
           OF NORTHERN STATES POWER COMPANY, A WISCONSIN CORPORATION.
 
Gentlemen:
 
    For  the purpose of rendering this  opinion, I have examined the proceedings
taken by Northern States Power  Company, a Wisconsin corporation, herein  called
the  "Company," with respect to the issue and sale by the Company of $  ,000,000
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                 (the "Underwriting Agreement")
between you and the  Company relating to  your purchase of  the Bonds, and  have
either  participated in the preparation of or examined the Trust Indenture dated
April 1, 1947, the  12 Supplemental Trust  Indentures thereto, the  Supplemental
and  Restated Trust  Indenture dated March  1, 1991, and  the Supplemental Trust
Indenture dated as of                , creating the Bonds, all from the  Company
to  Firstar Trust Company (formerly known  as First Wisconsin Trust Company), as
Trustee (which  Trust Indenture  and Supplemental  Trust Indentures  are  herein
collectively   called  the  "Indenture").  I   have  also  participated  in  the
preparation of  or  examined the  registration  statement and  the  accompanying
prospectuses  and any supplements thereto, as  filed under the Securities Act of
1933, as amended (herein called the "Act"), with respect to the Bonds. The terms
"Registration Statement" and "Prospectus" as used herein shall have the meanings
ascribed to  such  terms  by  the Underwriting  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 Wisconsin; has corporate power, right, and authority to do business
    and to own property in the State of Wisconsin in the manner and as set forth
    in  the Prospectus; has no "significant  subsidiaries" within the meaning of
    Rule 1.02(v)  of Regulation  S-X under  the Act;  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, are fully paid and  non-assessable
    and are owned by Northern States Power Company, a Minnesota corporation;
 
        3.   The Underwriting 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 in the
    Underwriting Agreement may  be held  to be unenforceable  as against  public
    policy.
 
        4.   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  Michigan and Wisconsin  (where property  covered
    thereby  is  located)  affecting the  remedies  for the  enforcement  of the
    security provided in
 
                                       1
<PAGE>
    the Indenture (which states'  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;  and the Indenture constitutes a  valid mortgage effective to create a
    lien for  the security  of the  Bonds upon  the property  now owned  by  the
    Company  therein  specifically described  as  subject to  the  lien thereof,
    except as otherwise provided  therein with respect  to specific property  or
    classes of property;
 
        5.  The Indenture is in proper form, conforming to the laws of the State
    of  Wisconsin, 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 in the
    State of Wisconsin necessary to effectuate the lien of the Indenture.
 
        6.  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.  This opinion does not
    cover titles to easements  for water flowage purposes  or rights of way  for
    electric  and  or  gas  transmission and  distribution  facilities,  but the
    Company has the power of eminent domain  in the states in which it  operates
    and  such power may be  utilized by the Company to  cure defects in title to
    its real property;
 
        7.   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 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 exceptions set forth in Paragraph 6 above;
 
        8.  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
    Encumbrances 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 Code,  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;
 
        9.   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 Underwriting  Agreement has  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  qualification
    expressed   in  Paragraph  4   above  with  respect   to  the  validity  and
    enforceability  of  certain  of  the   provisions  of  the  Indenture)   are
    enforceable in accordance with their terms;
 
        10.   The  consummation   of  the   transactions  contemplated   in  the
    Underwriting  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
 
                                       2
<PAGE>
    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 government body having jurisdiction over the
    Company or its property;
 
        11. The Registration Statement has  become effective under the Act.  The
    Prospectus  Supplement (as defined  in the Underwriting  Agreement) has been
    filed pursuant to Rule 424(b)  under the Act and  no proceedings for a  stop
    order  have been  instituted or  to my  knowledge are  pending or threatened
    under Section 8(d) of  the Act; the Public  Service Commission of  Wisconsin
    has  issued its order  authorizing the issuance  and sale of  the Bonds; the
    Indenture has been duly qualified under the Trust Indenture Act of 1939,  as
    amended;  and no further approval  of, authorization, consent certificate or
    order of any governmental body, federal,  state (other than the approval  of
    the  Michigan Public Service Commission) or other, is required in connection
    with the issuance and sale of the Bonds by the Company to you as provided in
    the Underwriting Agreement, except as may be required by "blue sky" or state
    securities laws;
 
        12. At the time the Registration  Statement became effective and at  the
    date  of the Underwriting Agreement,  the Registration Statement (other than
    the financial statements  and supporting schedules  included therein, as  to
    which  no opinion is rendered) complied as  to form in all material respects
    with the  requirements of  the Act,  the  Trust Indenture  Act of  1939,  as
    amended, and the rules and regulations thereunder;
 
        13.  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.
 
        14.  The Company has all necessary  power under statutory provisions and
    permits to use its operating electric and gas properties; and
 
        15.  All  statements  contained   in  the  Registration  Statement   and
    Prospectus  purporting  to set  forth my  opinion or  to be  based up  on my
    opinion correctly set forth my opinion on said respective matters.
 
    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 up  on  and do  not  assume
responsibility  for and shall  not be deemed to  have independently verified the
accuracy,  completeness  or  fairness  of  the  Registration  Statement  or  the
Prospectus  (except as  to matters  set forth  in Paragraphs  12 and  15 above),
nothing has  come  to my  attention  that would  lead  me to  believe  that  the
Registration  Statement at the  time it became  effective or at  the date of the
Underwriting Agreement  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 at the date of
the Underwriting  Agreement  or  as  of 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 the  light of the circumstances  under
which they were made, not misleading.
 
    In   giving  my  opinion  under  Paragraph  6  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
 
                                       3
<PAGE>
which would  adversely affect  the  titles shown  on  the abstracts.  In  giving
opinions  as to titles to property of the Company, I also, in certain instances,
relied upon the opinion of other counsel employed or retained by the Company  to
render opinions in respect thereto.
 
                                          Respectfully submitted,

              ,  at  his option  may surrender  the  same at  the office  of the

thereupon,  and upon  receipt of  any payment  required under  the provisions of
Section 2.04 hereof, the  Company shall execute and  deliver to the Trustee  and

    SECTION 2.05. (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
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 and interest on the bonds of the  Series due                and of
giving any notice permitted or required to be given to registered holders  under
the  Indenture, except  as provided  in Section  2.05(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  that 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 the bonds of the Series due
              ; any  notice  that  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
<PAGE>
                                       8
              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  New
York and Wisconsin), 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 2.05(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, [premium,  if any,] 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  certificates as
requested by DTC in appropriate amounts pursuant to Article II of the  Indenture
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  2.05(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 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
2.05(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 2.11 of the Indenture, 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.
 
    (e) In connection with any notice  or other communication to be provided  to
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
<PAGE>
                                       9
              , 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;  OR (4) 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 THE BONDS OF THE
SERIES DUE                  OR REGISTERED HOLDERS OF THE BONDS OF THE SERIES DUE
                 SHALL MEAN CEDE & CO. AND SHALL NOT MEAN THE BENEFICIAL  OWNERS

    (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
2.05 after which no substitute book-entry depository is appointed, the bonds  of
the  Series due                   shall be registered in  whatever name or names
registered  holders  transferring  or  exchanging   bonds  of  the  Series   due
              shall   designate  in  accordance  with   the  provisions  of  the
Indenture.
 
                                  ARTICLE III.
                                  SINKING FUND
 
    SECTION 3.01 (a)  The Company covenants  that it  will on the  first day  of
       of each year commencing          ,     , 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
       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     solely and entirely  through
the  application of  an Amount of  Established Permanent Addition  in the manner
hereinafter set forth in subdivision (c) of this Section 3.01.]
 
    (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           next following such delivery. If any bonds of the
Series due
<PAGE>
                                       10
              , 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          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)  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          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        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.
 
    (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  21.03
of  the  Indenture) 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 21.03 of the Indenture, except that, on and
after commencement of
<PAGE>
                                       11
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  of 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 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 shall at  all times 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  between $5,000,000  and $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 lawfully  be
merged  or converted or  with which it  may be consolidated,  or any corporation
resulting  from  any   merger,  conversion,  or   consolidation  to  which   any
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 may at any time 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.

Northern States Power Company
100 North Barstow Street
Eau Claire, Wisconsin 54701



Gentlemen:

I am participating in the proceedings being had and taken in connection with 
the issuance and sale by Northern States Power Company, a Wisconsin 
corporation (herein called the Company), of up to $65,000,000 principal 
amount of First Mortgage Bonds (herein called the New Bonds).  I have 
examined all statutes, records, instruments, and documents which, in my 
opinion, it is necessary to examine for the purpose of rendering the 
following opinion.

Based upon the foregoing and upon my general familiarity with the Company and
its affairs, as a result of having acted as General Counsel for the Company, I
am of the opinion that:

     1.   The Company was incorporated and is now a legally existing corporation
          under the laws of the State of Wisconsin; has corporate power, right,
          and authority to do business and to own property in that state, 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.   The Trust Indenture dated April 1, 1947 from the Company to Firstar
          Trust Company (formerly known as First Wisconsin Trust Company),
          Trustee, as supplemented by Supplemental Trust Indentures thereto
          dated March 1, 1949, June 1, 1957, August 1, 1964, December 1, 1969,
          September 1, 1973, February 1, 1982, March 1, 1982, June 1, 1986,
          March 1, 1988, the Supplemental and Restated Trust Indenture dated
          March 1, 1991, and the

                                                                  Page 2 of 2


          Supplemental Trust Indentures dated April 1,
          1991, March 1, 1993 and October 1, 1993 is a legal, valid, and binding
          instrument.

     3.   When and if (a) the above-mentioned Registration Statement becomes
          effective pursuant to the provisions of the Securities Act of 1933, as
          amended, (b) the Public Service Commission of Wisconsin issues its
          Order authorizing the issuance and sale of the New Bonds, (c) the
          Supplemental Trust Indentures from the Company to Firstar Trust
          Company, Trustee, relating to the New Bonds, are duly authorized,
          executed, delivered, filed, and recorded as required by law, and (d)
          the New Bonds are 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 in accordance with their terms and
          entitled to the benefits and security of said Trust Indenture, as
          supplemented.

Respectfully submitted,


John P. Moore, Jr.
General Counsel
