                        Report of Independent Accountants



To the Participants and Administrator
of the Minnesota Power and Affiliated
Companies Employee Stock Ownership
Plan and Trust


In our opinion,  the  accompanying  statements of net assets  available for plan
benefits and the related  statements of changes in net assets available for plan
benefits present fairly, in all material respects,  the net assets available for
plan benefits of the Minnesota  Power and  Affiliated  Companies  Employee Stock
Ownership  Plan and Trust at December 31, 1996, and 1995, and the changes in net
assets  available for plan benefits for the years then ended, in conformity with
generally accepted  accounting  principles.  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  generally  accepted  auditing
standards 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 the opinion expressed above.

Our audit was made for the purpose of forming an opinion on the basic  financial
statements taken as a whole. The additional  information included in Schedules I
and II is presented  for purposes of  additional  analysis and is not a required
part of the basic financial statements but is additional information required by
the Employee  Retirement  Income Security Act of 1974. Such information has been
subjected to the auditing procedures applied in the audit 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.

                    Minnesota Power and Affiliated Companies
                     Employee Stock Ownership Plan and Trust
                          Notes to Financial Statements



Note 1 - Description of the Plan

         The Minnesota Power and Affiliated  Companies  Employee Stock Ownership
Plan and Trust (ESOP)  provides  eligible  employees of Minnesota  Power & Light
Company (Minnesota Power); Superior Water, Light and Power Company; and MP Water
Resources Group, Inc.,  formerly Topeka Group Incorporated,  (collectively,  the
Companies) with Minnesota Power common stock (Common Stock) ownership  benefits.
The ESOP is a defined contribution plan that is subject to the provisions of the
Employee  Retirement  Income Security Act of 1974 (ERISA).  At December 31, 1996
there were 1,666 participants in the ESOP.

Basic Account

         Participants'  Basic Accounts received shares of Common Stock purchased
with incremental  investment  credit  contributions and payroll-based tax credit
contributions.  Contributions to the  participant's  Basic Accounts ceased after
1986.

         All participants' Basic Accounts are fully vested.  These shares can be
withdrawn  at any time.  Every  December  participants  are  required to make an
election to receive dividends on their shares either in cash or reinvest them in
Common Stock held in the ESOP.

Special Account

         For the years 1985 through 1989, the Companies received a tax deduction
for cash dividends paid to  participants  on ESOP shares in their Basic Account.
The Companies  contributed  to the ESOP an amount equal to the estimated  income
tax  benefit  of the  dividend  deduction  associated  with  shares in the Basic
Account.  Shares  of  Common  Stock  purchased  with  these  contributions  were
allocated to the  participants'  Special  Account.  All  participants  are fully
vested in these shares which can be withdrawn  when the  participants  terminate
employment.  Dividends on these shares are  automatically  reinvested  in Common
Stock held in the ESOP.

First Suspense Account

         In 1989 the ESOP was  amended to enable the ESOP  Trustee  (as  defined
below) to  establish  a  leveraged  First  Suspense  Account.  Employees  become
eligible to participate after one year of service with the Companies.  The First
Suspense  Account  originally  consisted  of  633,849  shares  of  Common  Stock
purchased for the benefit of eligible ESOP  participants with proceeds from a 15
year $16.5 million loan (First Loan) bearing  interest at 9.125%.  This loan was
obtained by the ESOP Trustee on December 29, 1989,  and  guaranteed by Minnesota
Power.  The First  Suspense  Account  provides that as the First Loan is repaid,
shares of Common  Stock in the First  Suspense  Account  are  allocated  to each
participant's  account based on the ratio of a participant's annual compensation
to the annual  compensation of all  participants.  In any year that the value of
the  shares  credited  to a  participant's  account  is  less  than  2%  of  the
participant's  annual  compensation,  the Companies will  contribute  additional
shares to make up the  difference.  Shares of Common Stock are also allocated to
participants'  accounts for reinvested dividends paid on the shares in the First
Suspense Account.  All participants are fully vested after 5 years of continuous
service with the Companies.

                                       4



Second Suspense Account

         Minnesota  Power  amended  the ESOP  again in 1990 to  enable  the ESOP
Trustee  to  establish  a  leveraged  Second  Suspense  Account  and  borrow  an
additional  $75 million  (Second  Loan) for the purpose of  acquiring  2,830,188
newly  issued  shares of Common  Stock from  Minnesota  Power for the benefit of
active ESOP  participants  with a basic  account.  Under this  amendment  active
participants  with a Basic Account are allocated shares to their Special Account
with a value at least  equal to: (a)  dividends  payable on shares held by those
participants in the ESOP who do not elect to receive  dividends in cash, and (b)
tax savings  generated  from the  deductibility  of dividends paid on all shares
held in the ESOP as of August 4,  1989.  Pursuant  to this  amendment,  the ESOP
Trustee issued a promissory  note to Minnesota Power for $75 million at a 10.25%
interest rate with a term not to exceed 25 years.

Administration

         The ESOP is  administered  for the  Companies by the  Employee  Benefit
Plans Committee (the Committee). The mailing address of the Committee is 30 West
Superior  Street,  Duluth,  Minnesota 55802. The Committee is authorized to make
rules and  regulations  as it may deem  necessary to carry out the provisions of
the ESOP and to employ  investment  managers  (as defined by ERISA),  attorneys,
accountants,  and such other persons as it shall deem  necessary or desirable in
the  administration  of the ESOP. The Committee  consists of 10 members who were
appointed by the Board of Directors of Minnesota  Power.  The Board of Directors
has the power to remove  members of the  Committee  from office.  Members of the
Committee receive no compensation for their services with respect to the ESOP.

ESOP Termination

         The Companies reserve the right to reduce, suspend or discontinue their
contributions  to the ESOP or to terminate  the ESOP in its entirety  subject to
the provisions of ERISA. In the event that the ESOP is terminated, the Committee
may  require  that  the  accounts  of  all  participants  and  beneficiaries  be
distributed  as  soon  after  the  termination   date  as  the  Committee  deems
practicable, regardless of the length of time Common Stock has been allocated to
any account.

Contributions

         The  Companies'  contribution  for each year  shall be paid to the ESOP
Trustee either in cash or in Common Stock.  Subject to a statutory maximum,  the
expenses  incidental to establishing and  administering the ESOP may be deducted
from the  Companies'  contributions  to the ESOP or income  earned by the shares
held in the ESOP.  Expenses not  attributable to such sources are payable by the
Companies. No fees or charges will be payable by any ESOP participant.

Transfers

         Upon  retirement,  participants may elect to transfer the vested amount
of their ESOP account  balances to the Minnesota Power and Affiliated  Companies
Retirement Plan A or Plan B.


Note 2 - Summary of Accounting Policies

         The ESOP uses the accrual basis of accounting and accordingly  reflects
income in the year earned and expenses when incurred.  Investments  are reported
at their fair value based on quoted market price.


Note 3 - Federal Income Tax Status

         A favorable  determination  letter dated  January 30, 1996 was obtained
from the Internal Revenue Service stating that the ESOP, as amended and restated
effective  January 1, 1992,  qualifies as an employee stock ownership plan under
Section 401(a) of the Internal Revenue Code of 1986.


Note 4 - Investments

         The ESOP's investments,  at December 31, are presented in the following

Note 5 - Repayment of Loans

         The ESOP  Trustee will repay  principal  and interest on the First Loan
and  Second  Loan with  dividends  paid on the  shares  of Common  Stock in each
suspense account and with certain employer contributions to the ESOP. The shares
of Common Stock  acquired by the ESOP Trustee will be held in the First Suspense
Account  and Second  Suspense  Account  and  allocated  to the  accounts of ESOP
participants  as the First Loan and Second  Loan are repaid.  Under  current tax
law, the Companies expect to realize tax savings from the two transactions.

         The First Loan was obtained from a third party lender and is guaranteed
by the  Companies  with 360,233  unallocated  shares of Common Stock  pledged as
collateral  at December  31,  1996.  Principal  payments  for the First Loan are
