DAVID G. GARTZKE
CHAIRMAN, ALLETE BOARD OF DIRECTORS

                                        August 24, 2004

Dear Shareholder:

         Your board of directors has taken action on several issues related to
the upcoming separation of ADESA from ALLETE. These matters are important to all
ALLETE shareholders, and I urge you to read this letter carefully. We have
enclosed with this mailing a question-and-answer sheet and a copy of a news
release we issued. I want you to fully understand this transaction and the key
events that will transpire over the next month.

SPIN-OFF OF ADESA TO ALLETE SHAREHOLDERS:
- -----------------------------------------

         I'm pleased to report that the SPIN-OFF OF ADESA (NYSE:KAR) FROM ALLETE
(NYSE:ALE) WILL TAKE PLACE SEPTEMBER 20, 2004. ON THAT DAY, INVESTORS WHO OWN
SHARES OF ALLETE ON THE RECORD DATE OF SEPTEMBER 13, 2004, ARE EXPECTED TO
RECEIVE ONE SHARE OF ADESA STOCK FOR EACH SHARE OF ALLETE THEY HOLD.
Shareholders of ALLETE will receive their ADESA shares in direct registration
form. Within days after the spin-off, all ALLETE shareholders of record will
automatically receive a statement of ownership from ADESA and a check for any
fractional share. NO ACTION IS REQUIRED BY YOU TO RECEIVE YOUR SHARES OF ADESA.

         The distribution of ADESA common stock is structured to qualify as a
tax-free stock dividend. The result is that you will not recognize a taxable
gain or loss as a result of the receipt of ADESA common stock, except with
respect to any cash you may receive for a fractional share. You will receive
information that will help you calculate the tax basis of your ADESA and ALLETE
shares after the spin-off.

ONE-FOR-THREE REVERSE STOCK SPLIT:
- ----------------------------------

         The ALLETE board of directors has also declared a one-for-three reverse
stock split, effective immediately following the spin-off on September 20,
whereby every three shares of ALLETE that you own will be converted into one
share of "new" ALLETE common stock.

         This reverse split will not affect your investment interest in ALLETE
and is intended to increase the share price to a range that is more appealing to
a broader group of investors. Here's an example of how the reverse split will
work. Let's say you own 300 shares of post-spin-off ALE priced at $9 per share
before the reverse split on September 20, 2004. Immediately after the reverse
stock split, you would have 100 shares of ALE priced at $27 per share. In both
cases, the value of your investment is $2,700.

August 24, 2004                                                           Page 2

         Investors who hold ALLETE shares in stock certificate form will have to
turn in their certificates to the Company's transfer agent, Wells Fargo Bank
N.A., after the spin-off to receive their "new" ALLETE shares. The "new" shares
will be in direct registration form, and shareholders will receive a statement
of ownership and a check for any fractional share. PLEASE DO NOT SEND IN YOUR
CERTIFICATES NOW; INSTRUCTIONS ON HOW TO DO SO WILL BE SENT TO YOU IN LATE
SEPTEMBER.

         Investors who hold ALLETE shares within the Invest Direct stock
purchase and dividend reinvestment plan will not have to take any action to
receive their "new" shares. The changed price and quantity of your shares will
be reflected in the next Invest Direct statement you receive after the spin-off.

ALLETE COMMON STOCK DIVIDEND:
- -----------------------------

         ALLETE'S September 1 common stock dividend will be the same as the
previous quarter's dividend of $0.2825 per share. The ALLETE BOARD OF DIRECTORS
ANTICIPATES DECLARING A QUARTERLY DIVIDEND OF $.30 PER POST-SPLIT SHARE at its
regular October meeting for payment on December 1, 2004 to shareholders of
record on November 15, 2004.

NOTICE TO PARTICIPANTS IN THE INVEST DIRECT PLAN:
- -------------------------------------------------

         In order to facilitate appropriate record keeping for these
transactions, the company will be suspending all sales and transfer activity in
its Invest Direct stock purchase plan from September 10 until September 20.
Optional cash payments received after August 25 will buy shares in post-spin-off
ALLETE.

         It's gratifying for all of us at ALLETE and ADESA to be reaching the
point where these two fine companies are able to pursue their strategies
independently. It has been my distinct pleasure to serve as ALLETE's board
chairman during a period of growth and change. As I leave ALLETE to devote my
full attention to the leadership of ADESA, you may be assured that your
investment in both companies is very much appreciated.

Sincerely,

/s/ David G. Gartzke

    QUESTIONS AND ANSWERS


    How the transactions
    work for you.
             ----

      [ALLETE LOGO]



                 THE ADESA spin-off.

- - Q.  What am I going to receive when ADESA
      is spun off?
  A.  On September 20, ALLETE expects to distrib-
  ute one share of ADESA stock for every share of
  ALLETE stock you own as of September 13, and
  a check for the value of any fractional share. Your
  ADESA shares will be held in a Direct Registration
  System (DRS) account managed by Wells Fargo
  Bank N.A., ADESA's transfer agent.

- ------------------------------------------------------

- - Q.  Do I have to do anything to receive my
      ADESA shares?
  A.  No, you will not have to do anything to
  receive your shares. You will automatically be
  mailed a statement from ADESA reflecting your
  ownership.

- ------------------------------------------------------

- - Q.  What is DRS and how does it work?
  A.  DRS is a system for book-entry ownership
  of stock. It is a service in which shares are
  owned, recorded and transferred electronically
  without issuing a physical stock certificate.
  By having the transfer agent keep shareholder
  records electronically, the risk of lost or stolen
  stock certificates is eliminated. Shareholders still
  have all their traditional rights and privileges,
  without the necessity of holding a physical
  certificate. You will receive information on how
  to perform transactions within your DRS account
  when you receive your new statement of owner-
  ship. A physical stock certificate will be issued
  only upon request.

- ------------------------------------------------------

- - Q.  What happens if I buy or sell shares of
      ALLETE before the spin-off date?
  A.  If you buy ALLETE stock before September
  21, you'll be eligible for the ADESA spin-off shares.
  If you sell shares of ALLETE prior to September 21
  you will also sell your entitlement to receive any

  corresponding ADESA spin-off shares. Please note
  that transactions in ALLETE's Invest Direct plan
  will be suspended between September 10 and
  September 20 to accommodate recordkeeping.

- ------------------------------------------------------

- - Q.  What is a reverse stock split?
  A.  It is the opposite of a stock split. A reverse
  split results in a decrease in the number of out-
  standing shares with a proportionate increase in
  the price per share so that the total value of the
  stock owned remains the same. For example, if
  a shareholder owned 300 shares of ALLETE stock
  valued at $9 per share immediately after the spin-
  off of ADESA, he would own 100 shares valued at
  $27 after the one-for-three reverse stock split.
  In both cases the total value of his investment
  equals $2700.

- ------------------------------------------------------

- - Q.  Why was a reverse stock split declared?
  A.  Our research indicates that common stock
  priced over $20 appeals to more investors than
  stock that is priced well under that level. Since
  ALLETE stock would likely trade at a price well
  under $20 immediately after the spin-off of ADESA,
  the board declared a one-for-three reverse stock
  split with the intention of increasing the price to
  a range that is more appealing to a broader group
  of investors.



                A NEW ALLETE dividend.

- - Q.  What do I need to do to receive my "new"
      ALLETE shares after the reverse split?
  A.  If you currently hold a stock certificate,
  it must be turned in. You should do nothing
  now; you will receive instructions in late
  September about how to turn in your old
  stock certificates. After you surrender your
  old certificate, you will automatically be mailed
  a new DRS statement of ownership from
  ALLETE and a check for any fractional share.
      If you hold your stock within an Invest
  Direct account, you do not have to do
  anything. Your next Invest Direct statement
  will reflect your share ownership.

- ------------------------------------------------------

- - Q.  What will the common dividend be?
  A.  The September 1 common stock dividend
  of $0.2825 per share remains unchanged from
  the previous quarter. The ALLETE board of
  directors expects to declare a quarterly
  dividend of $0.30 per post-split share
  (which would be equivalent to $0.10 per
  pre-split share) at its regular October meeting
  for payment on December 1, 2004 to share-
  holders of record on November 15, 2004.
