                        REPORT OF INDEPENDENT ACCOUNTANTS



To the Participants and Administrator of
the Minnesota Power and Affiliated
Companies Supplemental Retirement Plan

In our opinion, the accompanying statements of net assets available for benefits
and the  related  statements  of changes in net assets  available  for  benefits
present fairly, in all material respects,  the net assets available for benefits
of the Minnesota  Power and Affiliated  Companies  Supplemental  Retirement Plan
(the  "Plan")  at  December  31,  2000 and 1999,  and the  changes in net assets
available  for  benefits  for the  year  ended  in  conformity  with  accounting
principles  generally accepted in the United States of America.  These financial
statements are the responsibility of the Plan's  management;  our responsibility
is to express an opinion on these financial  statements based on our audits.  We
conducted our audits of these  statements in accordance with auditing  standards
generally  accepted in the United States of America,  which require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement.  An audit includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements,  assessing the accounting  principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

Our audits  were  conducted  for the  purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental Schedule of Assets (Held
at End of Year) is presented for the purpose of additional analysis and is not a
required part of the basic financial statements but is supplementary information
required by the  Department of Labor's Rules and  Regulations  for Reporting and
Disclosure  under the Employee  Retirement  Income  Security  Act of 1974.  This
supplemental  schedule  is the  responsibility  of the  Plan's  management.  The
supplemental  schedule has been subjected to the auditing  procedures applied in
the audits of the basic  financial  statements  and, in our  opinion,  is fairly
stated in all material  respects in relation to the basic  financial  statements
taken as a whole.

                          NOTES TO FINANCIAL STATEMENTS


NOTE 1 - DESCRIPTION OF THE PLAN

         The Minnesota Power and Affiliated  Companies  Supplemental  Retirement
Plan (SRP) provides benefits for eligible employees of participating  affiliated
companies:  ALLETE, Inc. (ALLETE),  Minnesota Power (a business unit of ALLETE),
Superior Water, Light and Power Company, Minnesota Power Telecom, Inc., Electric
Outlet, Inc. and MP Affiliated Resources,  Inc.  (collectively,  the Companies).
The SRP is a  contributory  defined  contribution  plan that is  subject  to the
provisions of the Employee  Retirement  Income  Security Act of 1974, as amended
(ERISA).

CONTRIBUTIONS

      -  PARTICIPANT CONTRIBUTIONS to the SRP consist of the following:

             - FLEXIBLE DOLLAR  CONTRIBUTIONS.  Non-union  participants may make
               flexible  dollar  contributions  of  up  to 3  percent  of  their
               compensation,  subject to a maximum  compensation  of $170,000 in
               2000.  The   contribution   is  included  in  the   participant's
               before-tax account.

             - BEFORE-TAX  CONTRIBUTIONS.  Before-tax  contributions consist  of
               salary reduction contributions and results sharing contributions.
               Total before-tax contributions may not exceed $10,500 in 2000, as
               permitted  under Section  401(k) of the Internal  Revenue Code of
               1986 (Code).

               - SALARY  REDUCTION CONTRIBUTIONS. Salary reduction contributions
                 are equal to an amount the  participant  has  elected to reduce
                 his  or  her  compensation   pursuant  to  a  salary  reduction
                 agreement.

               - RESULTS  SHARING  CONTRIBUTIONS. Results sharing  contributions
                 are equal to the  portion  (up to 100  percent)  of the Results
                 Sharing Award the participant  irrevocably  agrees to forgo and
                 that,  pursuant to the Minnesota Power Results Sharing Program,
                 would otherwise be paid to the participant.

             - VOLUNTARY   CONTRIBUTIONS   (AFTER-TAX    CONTRIBUTIONS).    Each
               participant   is  also  allowed  to  make   voluntary   after-tax
               contributions  to the SRP through payroll  deductions or lump-sum
               contributions.   Total   voluntary   contributions   made   by  a
               participant  for all  fiscal  years  since July 1, 1980 shall not
               exceed 8.5 percent of the aggregate compensation received for all
               years since  becoming a participant  less the amount of voluntary
               contributions  made to either the Minnesota  Power and Affiliated
               Companies Retirement Plan A or Plan B.

             - ROLLOVERS.   Contributions  by  participants  may  also  be  made
               through rollovers from other qualified plans.

      -  EMPLOYER CONTRIBUTIONS to the SRP consist of non-elective contributions
         equal to 0.75 percent of each union participant's compensation, up to a
         maximum  compensation of $170,000 in 2000.  Employer  contributions are
         included in the participant's before-tax account.

VESTING

         All  contributions  plus actual  earnings  thereon are fully vested and
nonforfeitable.

LOAN PROGRAM

         The SRP allows participants to borrow money from their SRP accounts.  A
participant  may borrow up to $50,000  or 50 percent of their  total  before-tax
account  balances,  whichever  is less,  for  terms up to 5 years  for a general
purpose loan and 10 years for the  acquisition of a primary  residence.  A fixed
interest rate of the prime rate plus 1 percent,  but not less than the Minnesota
Power  Employees  Credit Union share  secured rate, is charged until the loan is
repaid. As loans are repaid, generally through payroll deductions, principal and
interest amounts are redeposited into the participant's SRP accounts.

PARTICIPANT ACCOUNTS

         Each   participant's   account  is  credited  with  the   participant's
contribution  and their share of the Companies'  contributions.  Income from the
various SRP investment  funds is allocated to each  participant's  account based
upon their ownership interest in each fund.

         Every December  participants are required to make an election as to the
level  of  contributions  to the SRP  for  the  subsequent  year.  Funds  may be
transferred  between  investment options on a weekly basis with at least 10 days
written notice to Minnesota Power's Benefits  Accounting and  Administration.  A
brief  description  of the Plan's  investment  options  follows.  For a detailed
description of the investment  options and respective risk profiles refer to the
fund prospectus.

             income by investing in the common stock of ALLETE.

         -   THE  MERIDIAN  VALUE FUND  seeks  long-term  growth  of  capital by
             investing  primarily in a diversified  portfolio of publicly traded

             Fund in 2000.

         -   FIDELITY MAGELLAN FUND  seeks capital  appreciation by investing in
             securities of domestic, foreign and multinational issuers.

         -   VANGUARD  INSTITUTIONAL INDEX FUND  seeks  to match,  as closely as

             Stock Price Index, which invests in stocks of large U.S. companies.

         -   VANGUARD MID-CAP INDEX FUND  seeks to match  the performance of the
             Standard & Poor's  MidCap 400 Index  which is made up of a group of
             medium-size U.S.  companies.  This fund replaced the Vanguard Short

         -   THE  ARTISAN  INTERNATIONAL FUND  seeks  maximum long-term  capital
             growth  by  investing  in  a  broadly   diversified   portfolio  of
             international   growth  stocks,   concentrating  on  industries  or
             investment  themes that present  accelerating  growth prospects and
             companies  that  capitalize  on that  growth.  This  fund  replaced
             Templeton Institutional Funds, Inc. Foreign Equity Series in 2000.

         -   BLACKROCK FUNDS SMALL CAP GROWTH EQUITY PORTFOLIO  seeks  long-term
             capital  appreciation  by  investing in U.S.  small  capitalization
             growth companies (market capitalization under $2 billion) which are
             considered to have  above-average  earnings growth prospects versus
             the fund's benchmark, the Russell 2000 Growth Index.

         -   THE NICHOLAS-APPLEGATE EMERGING COUNTRIES INSTITUTIONAL FUND  seeks
             maximum  long-term capital  appreciation by investing  primarily in
             stocks of companies  located in countries with emerging  securities
             markets.  This fund replaced  Templeton  Institutional  Funds, Inc.
             Emerging Market Series in 2000.

         -   JANUS BALANCED FUND seeks long-term capital  growth consistent with
             preservation of capital and balanced by current  income.  This fund
             invests in securities selected primarily for their growth or income
             potential.

         -   FIXED INCOME  FUND  consists  of  guaranteed  investment  contracts

                diversified pool of stable value contracts of  varying maturity,
                size and yield. This fund seeks to preserve principal and income
                while maximizing current income by investing in pooled insurance
                investment contracts, bank investment contracts and stable value
                contracts.

         While  participants are active employees,  they may withdraw money as a
loan from their before-tax account.  After age 59 1/2, participants may withdraw
the full amount of their before-tax account. After-tax accounts may be withdrawn
at specified times during the year by participants of any age. When participants
terminate  employment,  become disabled or die, they or their  beneficiaries may
elect to receive the vested  amount of all their SRP accounts.  Upon  retirement
participants  may elect to  transfer  the  vested  amount  of their SRP  account
balances to the Minnesota  Power and Affiliated  Companies  Retirement Plan A or
Plan B. The amount of those transfers  totaled $478,000 for 2000 ($1,107,000 for
1999).

         Minnesota  Power  maintains  the  participants'  records  and  issues a
quarterly report to each participant showing the status of individual  accounts.
At December 31, 2000 there were 1,673 participants in the SRP.

PLAN TERMINATION

         The Companies reserve the right to reduce, suspend or discontinue their
contributions  at any time or to terminate the SRP subject to the  provisions of
ERISA and the Code. In the event of SRP termination, all of the account balances
of the participants will be fully vested and  nonforfeitable,  and distributions
will be made in accordance with the terms of the SRP.


NOTE 2 - SUMMARY OF ACCOUNTING POLICIES

         The SRP uses the accrual basis of accounting and, accordingly, reflects
income in the year earned and expenses when incurred.

         Mutual  funds,  money  market  securities  and ALLETE  common stock are
reported at fair value based on quoted  market  prices.  GIC and PIC amounts are
reported at contract  value which  represents the purchase price of the contract
plus accrued interest.  Participants' loans are reported at estimated fair value
which represents outstanding principal and any related accrued interest.

         The  preparation of financial  statements in conformity with accounting
principles   generally  accepted  in  the  United  States  of  America  requires
management to:

         -  make estimates and  assumptions  that affect the reported amounts of
            assets and liabilities;

         -  disclose   contingent liabilities  at  the date  of   the  financial
            statements; and

         -  report  amounts of revenue and expense during the reporting  period.
            Actual  results  could differ from those estimates.

         The Plan presents in the  statement of changes in assets  available for
benefits the net appreciation (depreciation) in the fair value of its investment
which consists of the realized  gains or losses and the unrealized  appreciation
(depreciation) on those investments.

* Party in Interest


The  Plan's  assets  include  guaranteed  investment  contracts  with  crediting
interest  rates  ranging from 5.88% to 6.67%.  These  contracts had an aggregate
contract value of $6,910,000 at December 31, 2000  ($12,362,000  at December 31,
