northeastern Minnesota.  The Company's wholly owned subsidiary,  Superior Water,
Light and Power Company,  sells  electricity to 14,000 customers and natural gas

generating  cooperatives,  Minnkota  Power  Cooperative,  Inc.  and Square Butte
Electric  Cooperative  (Square Butte),  presently  consume  virtually all of BNI
Coal's  production  of lignite  coal under coal supply  agreements  extending to
2027. Under an agreement with Square Butte, Minnesota Power purchases 71 percent
of the output from the Square  Butte unit which is capable of  generating  up to
470 megawatts.

     In 1996 large industrial customers  contributed about half of the Company's
electric operating revenue.  The Company has large power contracts to sell power
to eleven  industrial  customers (five taconite  producers,  four paper and wood
products  manufacturers and two pipeline  companies) each requiring 10 megawatts
or more of power.  These contracts,  which have  termination  dates ranging from
October 1999
                                      -3-

associated with having the capacity available to serve these customers.

independently  owned  auctions,  and  5  outside  loan  production  offices  not

earnings  and cash flow  contributions  and is  available  for  reinvestment  in
existing  businesses,  acquisitions  and other corporate  purposes.  The Company

                                      -5-



     The Company has a Dividend Reinvestment and Stock Purchase Plan (Plan). The
Plan provides  investors  (Participants)  with a convenient  method of acquiring
shares of Common Stock through (i) the  reinvestment in Common Stock of all or a
portion of the cash dividends  payable on the  Participant's  holdings of Common
Stock and Preferred Stocks, and/or (ii) the investment of optional cash payments
pursuant to the terms of the Plan.  The Company  reserves  the right to suspend,
modify,  amend or terminate  the Plan at any time and to interpret  and regulate
the Plan as it deems  necessary or desirable in connection with the operation of
the Plan.  Shares of Common  Stock are  offered  for sale under the Plan only by
means of a separate prospectus available upon request from the Company.

                           DESCRIPTION OF COMMON STOCK

     General.  The following  statements relating to the Common Stock are merely
an  outline  and do not  purport to be  complete.  They are  qualified  in their
entirety by reference to the Company's  Articles of  Incorporation  (Articles of
Incorporation)  and the Mortgage and Deed of Trust of the Company.  Reference is
also made to the laws of the State of Minnesota.

     The Company's  authorized  capital stock  consists of 65,000,000  shares of
Common Stock,  without par value, 116,000 shares of 5% Preferred Stock, $100 par
value,  1,000,000  shares of Serial  Preferred  Stock,  without  par value,  and
2,500,000 shares of Serial Preferred Stock A, without par value.

     Dividend  Rights.  The Common Stock is entitled to all dividends after full
provision for dividends on the issued and outstanding  Preferred  Stocks and the
sinking fund  requirements  of the Serial  Preferred  Stock A, $7.125 Series and
$6.70 Series.

     The  Articles of  Incorporation  provide  that so long as any shares of the
Company's  Preferred Stocks are outstanding,  cash dividends on Common Stock are
restricted  to 75 percent of available net income when Common Stock equity is or
would   become  less  than  25  percent  but  more  than  20  percent  of  total
capitalization. This restriction becomes 50 percent when such equity is or would
become less than 20 percent.  See Note 7 to  Consolidated  Financial  Statements
incorporated by reference in the Company's 1996 Form 10-K.

     Voting Rights (Non-Cumulative Voting). Holders of Common Stock are entitled
to notice  of and to vote at any  meeting  of  shareholders.  Each  share of the
Common  Stock,  as well as each share of the issued  and  outstanding  Preferred
Stocks,  is entitled  to one vote.  Since the holders of such shares do not have
cumulative  voting  rights,  the  holders  of more than 50 percent of the shares
voting can elect all the Company's  directors,  and in such event the holders of
the remaining  shares voting (less than 50 percent)  cannot elect any directors.
In addition, the Preferred Stocks are expressly entitled, as one class, to elect
a majority  of the  directors  (the Common  Stock,  as one class,  electing  the
minority) whenever dividends on any of such Preferred Stocks shall be in default
in the amount of four quarterly payments and thereafter until all such dividends
in default shall have been paid. The Articles of Incorporation  include detailed
procedures and other provisions  relating to these rights and their termination,
such as quorums, terms of directors elected,  vacancies, class voting as between
Preferred Stocks and Common Stock, meetings, adjournments and other matters.

     The Articles of  Incorporation  contain  certain  provisions  which make it
difficult to obtain control of the Company through  transactions  not having the
approval of the Board of Directors, including:

     (1) A  provision  requiring  the  affirmative  vote  of 75  percent  of the
         outstanding  shares of all  classes  of capital  stock of the  Company,
         present and entitled to vote, in order to authorize  certain  "Business
         Combinations."  Any  such  Business  Combination  is  required  to meet
         certain "fair price" and procedural requirements.  Neither a 75 percent
         stockholder  vote  nor  "fair  price"  is  required  for  any  Business
         Combination which has been approved by a majority of the "Disinterested
         Directors."

     (2) A provision  permitting  a majority of the  Disinterested  Directors to
         determine whether the above requirements have been satisfied.

     (3) A provision  providing  that certain of the  Articles of  Incorporation
         cannot be altered  unless  approved  by 75  percent of the  outstanding
         shares of all classes of capital  stock,  present and 

                                      -6-

         entitled to vote, unless such alteration is recommended to the 
         shareholders by a majority of the Disinterested Directors.

     Liquidation Rights. After satisfaction of creditors and of the preferential
liquidation  rights of the  outstanding  Preferred  Stocks  ($100 per share plus
unpaid accumulated  dividends),  the holders of the Common Stock are entitled to
share ratably in the distribution of all remaining assets.

     Miscellaneous. Holders of Common Stock have no preemptive or conversion 
rights.

     The Common Stock is listed on the New York Stock Exchange.

     The transfer agents and registrars for the Common Stock are Norwest
Bank Minnesota, N.A. and the Company.

                 DESCRIPTION OF PREFERRED SHARE PURCHASE RIGHTS

     Reference  is made to the  Rights  Agreement,  dated  as of July  24,  1996
(Rights Plan) between the Company and the Corporate Secretary of the Company, as
Rights Agent.  The description of the Rights set forth below does not purport to
be complete  and is  qualified  in its entirety by reference to the Rights Plan.
Reference is also made to the laws of the State of Minnesota.

     On July 24, 1996, the Board of Directors of the Company declared a dividend
distribution  of one  Right  for  each  outstanding  share  of  Common  Stock to
shareholders  of record at the close of business on July 24, 1996 (Record  Date)
and  authorized  the  issuance of one Right with respect to each share of Common
Stock that becomes outstanding between the Record Date and July 23, 2006 or such
earlier time as the Rights are redeemed.  Except as described below, each Right,
when  exercisable,  entitles the registered  holder to purchase from the Company
one  one-hundredth  of a share of Junior Serial  Preferred  Stock A, without par
value (Serial  Preferred),  at a price of $90 per one  one-hundredth  share (the
Purchase Price), subject to adjustment.

     No separate  Right  Certificates  will be  distributed.  The Rights will be
evidenced by the Common Stock  certificates  together with a copy of the Summary
of Rights  Plan and not by separate  certificates  until the earlier to occur of
(i) 10 days following a public announcement that a person or group of affiliated
or associated persons (an Acquiring Person) has acquired,  or obtained the right
to acquire, beneficial ownership of 15 percent or more of the outstanding shares
of Common Stock (the Stock  Acquisition  Date) or (ii) 15 business days (or such
later date as may be determined by action of the Board of Directors prior to the
time that any person becomes an Acquiring  Person) following the commencement of
(or a public  announcement  of an intention to make) a tender or exchange  offer
if, upon  consummation  thereof,  such  person or group would be the  beneficial
owner of 15  percent  or more of such  outstanding  shares of Common  Stock (the
earlier of such dates being called the Distribution Date).

     Until the  Distribution  Date, the Rights will be transferred with and only
with the Common  Stock.  Until the  Distribution  Date (or  earlier  redemption,
expiration or termination of the Rights),  the transfer of any  certificates for
Common  Stock,  with or without a copy of the Summary of Rights Plan,  will also
constitute  the  transfer  of  the  Rights  associated  with  the  Common  Stock
represented  by  such  certificates.   As  soon  as  practicable  following  the
Distribution   Date,   separate   certificates   evidencing  the  Rights  (Right
Certificates)  will be mailed to holders of record of the Common Stock as of the
close of business on the Distribution Date and, thereafter,  such separate Right
Certificates alone will evidence the Rights.

     Each  whole  share of Serial  Preferred  will  have a minimum  preferential
quarterly  dividend  rate equal to the  greater of $51 per share or,  subject to
anti-dilution  adjustment,  100 times the dividend declared on the Common Stock.
In the event of  liquidation,  no  distribution  will be made to the  holders of
Common Stock unless,  prior  thereto,  the holders of the Serial  Preferred have
received a  liquidation  preference  of $100 per share,  plus accrued and unpaid
dividends.  Holders of the Serial Preferred will be entitled to notice of and to
vote at any meeting of the  Company's  shareholders.  Each whole share of Serial
Preferred  is entitled to one vote.  Such shares do not have  cumulative  voting
rights. The Serial Preferred, together with the issued and outstanding shares of
the other Preferred Stocks of the Company,  will be expressly  entitled,  as one
class, to elect a majority of directors (the Common Stock electing the minority)
whenever  dividends  on any 

                                      -7-



of the  Preferred  Stocks  shall be in default  in the amount of four  quarterly
payments and  thereafter  until all such  dividends  in default  shall have been
paid. In the event of any merger,  consolidation  or other  transaction in which
shares of Common  Stock are  exchanged  for or converted  into other  securities
and/or  property,  each whole  share of Serial  Preferred  will be  entitled  to
receive, subject to anti-dilution adjustment, 100 times the amount into which or
for which each share of Common Stock is so exchanged or converted. The shares of
Serial Preferred are not redeemable by the Company.

     The Rights are not exercisable  until the Distribution Date and will expire
at the  earliest  of (i)  July  23,  2006  (Final  Expiration  Date),  (ii)  the
redemption  of the  Rights by the  Company  as  described  below,  and (iii) the
exchange of all Rights for Common Stock as described below.

     In the event that any person (other than the Company, its affiliates or any
person receiving  newly-issued shares of Common Stock directly from the Company)
becomes  the  beneficial  owner of 15  percent  or more of the then  outstanding
shares of Common Stock,  each holder of a Right will  thereafter have a right to
receive,  upon exercise at the then current exercise price of the Right,  Common
Stock (or, in certain  circumstances,  cash, property or other securities of the
Company) having a value equal to two times the exercise price of the Right.  The
Rights  Plan  contains an  exemption  for any  issuance  of Common  Stock by the
Company  directly  to any person  (for  example,  in a private  placement  or an
acquisition by the Company in which Common Stock is used as consideration), even
if that person  would become the  beneficial  owner of 15 percent or more of the
Common Stock,  provided that such person does not acquire any additional  shares
of Common Stock.

     In the event that, at any time  following the Stock  Acquisition  Date, the
Company is acquired in a merger or other business combination  transaction or 50
percent  or more of the  Company's  assets or  earning  power  are sold,  proper
provision will be made so that each holder of a Right will  thereafter  have the
right to receive, upon exercise at the then current exercise price of the Right,
common stock of the acquiring or surviving  company  having a value equal to two
times the exercise price of the Right.

     Notwithstanding  the  foregoing,  following  the  occurrence  of any of the
events set forth in the preceding two paragraphs  (the Triggering  Events),  any
Rights that are, or (under certain  circumstances  specified in the Rights Plan)
were,  beneficially  owned by any Acquiring Person will immediately  become null
and void.

     The Purchase Price payable, and the number of shares of Serial Preferred or
other securities or property issuable,  upon exercise of the Rights, are subject
to adjustment from time to time to prevent dilution,  among other circumstances,
in the event of a stock  dividend  on,  or a  subdivision,  split,  combination,
consolidation or reclassification  of, the Serial Preferred or the Common Stock,
or a reverse split of the outstanding  shares of Serial  Preferred or the Common
Stock.

     At any time after the  acquisition  by a person or group of  affiliated  or
associated  persons  of  beneficial  ownership  of 15  percent  or  more  of the
outstanding Common Stock and prior to the acquisition by such person or group of
50 percent or more of the outstanding  Common Stock,  the Board of Directors may
exchange the Rights (other than Rights owned by such person or group, which have
become void),  in whole or in part, at an exchange  ratio of one share of Common
Stock per Right (subject to adjustment).

     With  certain  exceptions,  no  adjustment  in the  Purchase  Price will be
required  until  cumulative  adjustments  require an  adjustment of at least one
percent  in the  Purchase  Price.  The  Company  will not be  required  to issue
fractional  shares of Serial  Preferred or Common Stock (other than fractions in
multiples of one  one-hundredths  of a share of Serial  Preferred)  and, in lieu
thereof,  an  adjustment  in cash may be made based on the  market  price of the
Serial  Preferred  or Common Stock on the last trading date prior to the date of
exercise.

     At any time after the date of the Rights  Plan until the time that a person
becomes an Acquiring  Person,  the Board of  Directors  may redeem the Rights in
whole, but not in part, at a price of $.01 per Right (Redemption  Price),  which
may (at the option of the  Company) be paid in cash,  shares of Common  Stock or
other  consideration  deemed  appropriate  by the Board of  Directors.  Upon the
effectiveness of any action of the Board of Directors ordering redemption of the
Rights,  the Rights will  terminate  and the only right of the holders of Rights
will be to receive the Redemption Price.

                                      -8-



     Issuance of Serial  Preferred or Common  Stock upon  exercise of the Rights
will be  subject  to any  necessary  regulatory  approvals.  Until  a  Right  is
exercised,  the holder thereof, as such, will have no rights as a shareholder of
the  Company,  including,  without  limitation,  the right to vote or to receive
dividends.  One million shares of Serial Preferred were reserved for issuance in
the event of exercise of the Rights.

     The  provisions  of the Rights Plan may be amended by the  Company,  except
that any  amendment  adopted  after the time that a person  becomes an Acquiring
Person may not adversely affect the interests of holders of Rights.

     The Rights  have  certain  anti-takeover  effects.  The  Rights  will cause
substantial  dilution to a person or group that  attempts to acquire the Company
without  conditioning  the offer on the Rights being  redeemed or a  substantial
number of Rights being  acquired,  and under  certain  circumstances  the Rights
beneficially  owned by such a person or group may become void. The Rights should
not  interfere  with any merger or other  business  combination  approved by the
Board of Directors  because,  if the Rights would become exercisable as a result
of such  merger of  business  combination,  the Board of  Directors  may, at its
option,  at any time  prior to the time that any  person  becomes  an  Acquiring
Person, redeem all (but not less than all) of the then outstanding Rights at the
Redemption Price.

prices.  Sales  may  be  made  to or  through  broker-dealers  who  may  receive
compensation  in the form of  discounts,  concessions  or  commissions  from the
Selling   Shareholders   and/or   the   purchasers   of  Shares  for  whom  such

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Section  302A.521  of the  Minnesota  Business  Corporation  Act  generally
provides  for the  indemnification  of  directors,  officers or  employees  of a
corporation  made or  threatened to be made a party to a proceeding by reason of
the  former or  present  official  capacity  of the  person  against  judgments,
penalties and fines  (including  attorneys' fees and  disbursements)  where such
person,  among other things,  has not been indemnified by another  organization,
acted in good faith,  received no improper  personal benefit and with respect to
any  criminal  proceeding,  had no  reasonable  cause to believe his conduct was
unlawful.

     Section 13 of the Bylaws of the Company  contains the following  provisions
relative to indemnification of directors and officers:

     "The Company shall  reimburse or indemnify each present and future director
and officer of the Company (and his or her heirs,  executors and administrators)
for or against all expenses  reasonably  incurred by such director or officer in
connection  with or arising out of any action,  suit or proceeding in which such
director or officer may be involved by reason of being or having been a director
or officer of the Company. Such indemnification for reasonable expenses is to be
to the fullest  extent  permitted by the  Minnesota  Business  Corporation  Act,
Minnesota  Statutes  Chapter 302A. By affirmative vote of the Board of Directors
or with  written  approval of the  Chairman and Chief  Executive  Officer,  such
indemnification  may be extended  to include  agents and  employees  who are not
directors or officers of the Company, but who would otherwise be indemnified for
acts and omissions under Chapter 302A of the Minnesota Business Corporation Act,
if such agent or employee were an officer of the Company."

     "Reasonable  expenses  may include  reimbursement  of  attorney's  fees and
disbursements,  including  those  incurred  by a person  in  connection  with an
appearance as a witness."

     "Upon written request to the Company and approval by the Chairman and Chief
Executive  Officer,  an agent or  employee  for  whom  indemnification  has been
extended,  or an officer or  director  may  receive  an advance  for  reasonable
expenses if such agent,  employee,  officer or director is made or threatened to
be made a party to a proceeding involving a matter for which  indemnification is
believed to be available under Minnesota Statutes Chapter 302A."

     "The  foregoing  rights shall not be exclusive of other rights to which any
director or officer may otherwise be entitled and shall be available  whether or
not the director or officer continues to be a director or officer at the time of
incurring such expenses and liabilities."

     The Company has insurance  covering its  expenditures  which might arise in
connection  with the lawful  indemnification  of its  directors and officers for
their  liabilities  and  expenses,  and insuring  officers and  directors of the
Company against certain other liabilities and expenses.

II-4 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 represent no more than a 20 percent change in maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; (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 paragraphs (i) and (ii) 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 paragraphs is contained in periodic reports filed with or furnished to the Commission by the registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement. (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. (4) 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 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. (5) 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, 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. II-5 POWER OF ATTORNEY Each person whose signature appears below hereby authorizes any agent for service named in this registration statement to execute in the name of each such person, and to file with the Securities and Exchange Commission, any and all amendments, including post-effective amendments, to the registration statement, and appoints any such agent for service as attorney-in-fact to sign in each such person's behalf individually and in each capacity stated below and file any such amendments to the registration statement and the registrant hereby also appoints each such agent for service as its attorney-in-fact with like authority to sign and file any such amendments in its name and behalf. SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Duluth, State of Minnesota, on November 21, 1997.

     Ladies and Gentlemen:

         We  refer  to the  Registration  Statement  on Form  S-3 to be filed by
     Minnesota Power & Light Company  (Company) on or about the date hereof with
     the Securities and Exchange Commission under the Securities Act of 1933, as
