Attn: Corporate Treasurer

Ladies and Gentlemen:

          Reference  is hereby made to that certain  Third  Amended and Restated

Committed  Facility  Letter  dated as of December  14, 2004  (together  with all
exhibits,  schedules,  attachments,   appendices  and  amendments  thereof,  the
"EXISTING  COMMITTED  FACILITY  LETTER").  The parties to the Existing Committed
Facility  Letter desire that the Existing  Committed  Facility Letter be amended
and restated in its entirety,  without constituting a novation, all on the terms
and conditions contained herein.  Accordingly,  in consideration of the premises
and the  agreements,  provisions and covenants  contained  herein,  the Existing
Committed  Facility  Letter is hereby amended and restated in its entirety to be

          LaSalle Bank National  Association (the "AGENT" and, in its individual
capacity, a "BANK") and the other Banks (as defined below) are pleased to advise
ALLETE,  Inc. (the  "COMPANY")  that the Banks  (defined  below) have  severally
approved,  subject to the  conditions  outlined in this letter  agreement  (this
"AGREEMENT"), a committed credit facility (the "FACILITY"). The amount available
under  the  Facility  shall  not  exceed  at any time the  aggregate  sum of the
Commitments  (defined  below) as may be increased or decreased from time to time
in  accordance  with the terms  hereof.  This  Facility  shall  terminate on the
Maturity  Date  (defined  below).  The  Facility  shall be  available  under the
following  terms and conditions  (certain  capitalized  terms being used and not
otherwise defined as set forth in SECTION 8):

     1.   LOANS.

          The  Company  may from time to time  before the  Maturity  Date borrow
Eurodollar  Loans,  or if one or more  conditions  exist as set forth in Section
3(b) or Section 3(c) hereof, Prime Rate Loans. The aggregate  outstanding amount
of the Loans shall not at any time exceed the aggregate  sum of the  Commitments
as increased or decreased in  accordance  with Section 1(d) hereof.  The Company
may borrow, repay and reborrow in accordance with the terms hereof.

          a.     BORROWING PROCEDURES

                 i.   PRIME RATE LOANS. Each  Prime Rate Loan shall be  on prior
          telephonic notice (promptly  confirmed in writing) from any Authorized
          Officer




ALLETE, Inc.

          received  by the Agent not later than 11:00  a.m.  (Chicago,  Illinois
          time),  on the day  such  Loan is to be  made.  Each  such  Notice  of
          Borrowing  shall  specify  (i) the  borrowing  date,  which shall be a
          Banking  Day,  and (ii) the  amount of the Loan.  Each Prime Rate Loan
          shall be in the amount of $5,000,000 or a higher integral  multiple of
          $1,000,000. A Prime Rate Loan shall only be available if the Agent has
          given written notice to the Company that one or more conditions  exist
          as set forth in Section 3(b) or Section 3(c) hereof.

                 ii.  EURODOLLAR LOANS. Each Eurodollar Loan  shall be made upon
          at least three Banking  Days' prior written or telephonic  notice from
          any Authorized  Officer received by the Agent not later than 3:00 p.m.
          (Chicago,  Illinois time). Each such Notice of Borrowing shall specify
          (i) the borrowing date,  which shall be a Banking Day, (ii) the amount
          of such  Loan,  and (iii) the  Interest  Period  for such  Loan.  Each
          Eurodollar  Loan  shall be in the  amount  of  $5,000,000  or a higher
          integral multiple of $1,000,000.

                 iii. The Agent shall give prompt telephonic or telecopy  notice
          to each Bank of the contents of each Notice of  Borrowing  and of such
          Bank's share of such Loan.

                 iv.  Not later  than  11:00 a.m. (Chicago time) (or  1:00  p.m.
          (Chicago time) in the case of any Prime Rate Loan) on the date of each
          borrowing,  each Bank participating  therein shall (except as provided
          in subsection  (v) of this  Section) make  available its share of such
          Loan, in Federal or other funds immediately  available in Chicago,  to
          the Agent at its address set forth next to its signature below. Unless
          the  Agent  is  notified  by a  Bank  that  any  applicable  condition
          specified in Section 4 has not been satisfied, the Agent will make the
          funds  so  received  from  the  Banks  available  to  the  Company  by
          depositing such funds in the manner specified in the related Notice of
          Borrowing.

                 v.   Unless the Agent  shall have received  notice from a  Bank
          prior  to the  date of any  borrowing  that  such  Bank  will not make
          available to the Agent such Bank's  share of such Loan,  the Agent may
          assume  that such Bank has made such share  available  to the Agent on
          the date of such borrowing in accordance  with subsection (iv) of this
          Section 1(a), and the Agent may, in reliance upon such assumption (but
          shall not be obligated to), make available to the Company on such date
          a corresponding  amount. If and to the extent that such Bank shall not
          have so made such  share  available  to the  Agent,  such Bank and the
          Company severally agree to repay to the Agent forthwith on demand such
          corresponding amount together with interest thereon, for each day from
          the date such amount is made  available to the Company  until the date
          such amount is repaid to the Agent, at (i) in the case of the Company,
          a rate per annum equal to the higher of (x) the Prime Rate and (y) the
          interest rate applicable  thereto  pursuant to Section  1(b)(ii),



ALLETE, Inc.
January 11, 2006
Page 3

          and (ii) in the case of such Bank,  the Prime Rate. If such Bank shall
          repay to the Agent such  corresponding  amount,  such amount so repaid
          shall  constitute  such Bank's Loan included in such Loan for purposes
          of this Agreement.

          b.     INTEREST

                 i.   PRIME RATE LOANS. The unpaid  principal of each Prime Rate
          Loan  shall bear  interest  to the  Maturity  Date at a rate per annum
          equal  to the  Prime  Rate  in  effect  from  time to  time  PLUS  the
          Applicable  Margin.  Accrued  interest  on Prime Rate  Loans  shall be
          payable  quarterly on the 30th day of each December,  March,  June and
          September and on the Maturity Date.

                 ii.  EURODOLLAR LOANS. The  unpaid  principal  amount  of  each
          Eurodollar  Loan shall bear  interest  prior to maturity at a rate per
          annum equal to LIBOR in effect for the Interest Period with respect to
          such Eurodollar Loan plus the Applicable  Margin.  Accrued interest on
          each  Eurodollar Loan shall be payable on the last day of the Interest
          Period  applicable  to such Loan and, if such  Interest  Period  shall
          exceed three months,  at three month  intervals  after the date of the
          Eurodollar Loan.

                 iii. INTEREST AFTER MATURITY. Any  principal of any  Loan which
          is  not  paid  when  due,  whether  at  the  stated   maturity,   upon
          acceleration or otherwise,  shall bear interest from and including the
          date such  principal  shall have become due to (but not including) the
          date of payment thereof in full at a rate per annum equal to the Prime
          Rate from time to time in effect PLUS the Applicable  Margin PLUS 2.0%
          per annum (but until the end of any  Interest  Period for a Eurodollar
          Rate  Loan,  not less  than  2.0 % in  excess  of the  rate  otherwise
          applicable for such Loan).  After maturity,  accrued interest shall be
          payable on demand.

                 iv.  MAXIMUM  RATE. In   no  event  shall  the   interest  rate
          applicable to any amount outstanding hereunder exceed the maximum rate
          of interest  allowed by applicable  law, as amended from time to time.
          Any payment of interest or in the nature of interest in excess of such
          limitation  shall be  credited  as a payment of  principal  unless the
          Company shall request the return of such amount.

                 v.   METHOD OF CALCULATING  INTEREST AND FEES. Interest on each
          Loan  shall  be  computed  on the  basis of a year  consisting  of (i)
          365/366,  as applicable,  days for Prime Rate Loans, and (ii) 360 days
          for Eurodollar Loans, and paid for actual days elapsed.  Fees shall be
          computed  on the basis of a year  consisting  of 360 days and paid for
          actual days elapsed.

          c.     DISBURSEMENTS AND PAYMENTS

          The Agent shall  transfer  the proceeds of each Loan as directed by an
Authorized Officer.  Each Eurodollar Loan shall be payable on the earlier of the
last day of the Interest  Period  applicable  thereto or the Maturity Date. Each
Prime Rate Loan shall be payable on the Maturity Date. All payments to the Banks
shall be made to the Agent at LaSalle Bank National  Association ABA No. 071 000
505, Account No. 1378018,  reference  ALLETE not later than 2:00 p.m.,  Chicago,
Illinois  time,  on the date when due and  shall be made in lawful  money of the
United  States  of  America  (in  freely   transferable  U.S.  dollars)  and  in
immediately  available  funds.  Any payment that shall be due on a day, which is
not a Banking  Day,  shall be payable on the next  Banking  Day,  subject to the
definition of "Interest Period".

          d.     PREPAYMENT; COMMITMENT INCREASES AND REDUCTIONS

          The  Company may prepay any Loan in whole or in part from time to time
(but, if in part, in an amount not less than  $1,000,000 and integral  multiples
of  $1,000,000 in excess  thereof)  without  premium or penalty  (subject to the
following  paragraph) upon (i) 3 Business Days prior written notice to the Agent
with respect to any Eurodollar  Loan and (ii) prior written notice  delivered to
the  Agent  prior to 10:00  a.m.  (Chicago,  Illinois  time) on the date of such
prepayment with respect to any Prime Rate Loan.

          If the Company shall prepay any Loan, it shall pay to the Agent at the
time of each prepayment,  or at such later time designated by the Agent, any and
all costs described in Section 3(g) hereof.

          The Company may permanently reduce the amount of Commitments from time
to time in amounts not less than $1,000,000 and integral multiples of $1,000,000
in excess thereof  without premium or penalty upon 3 Business Days prior written
notice to the Agent, provided that the aggregate amount of Commitments shall not
exceed  the  aggregate  principal  amount of Loans  then  outstanding.  Any such
reduction  shall be applied  ratably to the Commitments of the Banks and may not
be reinstated.

          The  initial  aggregate  amount of  Commitments  under this  Agreement
equals ONE HUNDRED FIFTY MILLION  DOLLARS  ($150,000,000).  Notwithstanding  the
foregoing to the contrary and so long as no Event of Default exists, the Company
may,  upon  written  election  delivered  to  Agent,  permanently  increase  the
aggregate Commitments under this facility by an amount not to exceed $50,000,000
to TWO HUNDRED MILLION DOLLARS  ($200,000,000)  (less the amount of any previous
reductions of the Commitments  pursuant to this Section 1(d)), by (a) increasing
the  Commitments of one or more Banks which have agreed to such increase  and/or
(b) adding one or more commercial  banks or other Persons as a Bank hereto (each
an  "ADDITIONAL  BANK")  with a  Commitment  in an amount  agreed to by any such
Additional  Bank;  PROVIDED  that no  Additional  Bank shall be added as a party
hereto without the written consent of the Agent (which shall not be unreasonably
withheld) or if an Event of Default then exists.  Any



ALLETE, Inc.
January 11, 2006
Page 5

such Commitment  increases shall be in minimum  aggregate amounts of $10,000,000
and  $5,000,000  multiples in excess  thereof.  In no event shall the  aggregate
Commitments  exceed  $200,000,000.  Any  increase in the  aggregate  Commitments
pursuant to this clause (d) shall be  effective  three  Business  Days after the
conditions  precedent date set forth in Section 4(c) are either fully  satisfied
or waived by Agent in writing.  The Agent shall promptly  notify the Company and
the Banks of any increase in the amount of the aggregate Commitments pursuant to
this Section and of the Commitment of each Bank after giving effect thereto. The
Company  acknowledges  that, in order to maintain Loans in accordance  with each
Bank's  pro-rata  share of all  outstanding  Loans prior to any  increase in the
aggregate   Commitments   pursuant  to  this  Section,  a  reallocation  of  the
Commitments as a result of a non-pro-rata  increase in the aggregate Commitments
may require  prepayment  of all or portions of certain Loans on the date of such
increase (and any such prepayment  shall be subject to the provisions of Section
3(g)).

          e.     NOTE

          The Company's obligations with respect to the Loans shall be evidenced
by a note for each Bank in the form  attached as EXHIBIT A (each,  a "NOTE" and,
collectively,  the "NOTES").  The amount, the rate of interest for each Loan and
the Interest Period (if applicable)  shall be endorsed by the respective Bank on
the  schedule  attached to its Note,  or at any Bank's  option,  in its records,
which schedule or records shall be conclusive,  absent manifest error, PROVIDED,
HOWEVER,  that the  failure  of any Bank to record any of the  foregoing  or any
error in any such record shall not limit or otherwise  affect the  obligation of
the  Company  to repay all Loans  made to it  hereunder  together  with  accrued
interest thereon.  The Company agrees to issue new notes to replace any existing
Notes if  requested  by Agent in the event that the  Commitments  are  increased
pursuant to the terms of Section 1(d) hereof.

          f.     MATURITY

          All of the  Obligations  shall  become due and payable on the Maturity
Date (as  defined  below) or upon the  earlier  termination  of this  Agreement.
Without limiting the foregoing,  all unpaid Obligations,  if not sooner declared
to be due in  accordance  with the terms  hereof,  together with all accrued and
unpaid  interest  thereon,  shall be due and payable in full on January 11, 2011
(the  "INITIAL  MATURITY  DATE")  or, if an  Extension  Option has been duly and
timely  exercised by the Company in  accordance  with the terms  hereof,  on the
applicable  Extended  Maturity  Date  (as  defined  below).  The  date  when all
Obligations are due and payable hereunder, whether the Initial Maturity Date, an
Extended  Maturity  Date, by  acceleration  or otherwise,  is referred to as the
"MATURITY DATE". Until all Obligations have been fully paid and satisfied (other
than contingent  indemnification  obligations to the extent no unsatisfied claim
with respect thereto has been asserted),  this Agreement shall continue in force
and effect for the benefit of Agent and the Banks and Agent shall be entitled to
exercise all rights and remedies  available to it hereunder and under applicable
laws.



ALLETE, Inc.
January 11, 2006

          Provided that no Event of Default then exists, either on the date that
the Company  delivers an Extension  Request or on the  applicable  Maturity Date
being  extended,  the Company shall have the right (the  "EXTENSION  OPTION") to
extend  the  term  of  this  Agreement  for  two  additional   12-month  periods
commencing,  in the  case of (i) the  first  Extension  Option,  on the  Initial
Maturity  Date and ending on January  11,  2012,  and (ii) the second  Extension
Option,  beginning  on January  11, 2012 and ending on January 11, 2013 (each an
"EXTENDED MATURITY DATE"),  upon and subject to the following terms,  provisions
and conditions:

          (i)    the Company shall deliver an  Extension Request to Agent of its
election to exercise the Extension Option in a timely manner as specified in the
definition of Extension Request,  accompanied by a statement  certifying that no
Event of Default then exists;

          (ii)   no condition or circumstance then exists which could reasonably
be expected to have, either individually or in the aggregate, a Material Adverse
Change;

          (iii)  Agent shall have  received notice on or before the date that is
10 Business Days prior to the then  applicable  anniversary  of the Closing Date
that Banks having Commitments in excess of 50% of the aggregate Commitments then
in effect  (after  giving  effect to any  concomitant  or  pending  increase  in
Commitments  being  made  pursuant  to  Section  1(d))  intend  to  renew  their
respective Commitments; and

          (iv)   except as expressly provided to the contrary in this Agreement,
all of the other terms,  provisions and conditions of this  Agreement,  the Note
and the Loan Documents  remain in full force and effect in accordance with their
respective terms,  including without limitation,  the obligation to make monthly
payments of interest at the then applicable interest rate.

          Each Bank may elect, in its sole and absolute discretion to extend its
Commitment in accordance  with the  Extension  Request of the Company.  Any Bank
failing to respond within 10 Business Days of receiving  written notice by Agent
of its receipt of an Extension  Request  shall be deemed to have declined and to
have  refused  to  consent  to  such  Extension  Request.  If  Banks  (including
Replacement  Banks,  as defined  below)  holding more than 50% of the  aggregate
amount of the renewed  Commitments  (after giving effect to any  concomitant  or
pending increase in Commitments  being made pursuant to Section 1(d)) consent to
the Extension  Request of the Company,  then the then  applicable  Maturity Date
shall be extended  by one  additional  year in  accordance  with such  Extension
Request,  but only with respect to those Banks  consenting to such  extension of
its Commitment.

          g.     REPLACEMENT OF NON-CONSENTING BANKS.

          If any Bank declines to extend the Maturity  Date in  connection  with
its Commitment  pursuant to an Extension  Request made by the Company,  then the
Company  may, at its sole  expense and effort,  upon notice to such Bank and the
Agent, require such Bank to



ALLETE, Inc.
January 11, 2006

assign and delegate,  without  recourse (in  accordance  with and subject to the
restrictions  contained in, and consents  required by, Section 9(o)), all of its
interests,  rights and  obligations  under this  Agreement  and the related Loan
Documents  to  an  assignee  (a  "REPLACEMENT  BANK")  that  shall  assume  such
obligations  (which  assignee  may  be  another  Bank,  if a Bank  accepts  such
assignment), PROVIDED that:

          (i)    the  Company  shall have  paid to the Agent the  assignment fee
specified in Section 9(o);

          (ii)   such Bank shall have received payment of an amount equal to the
outstanding  principal of its Loans, accrued interest thereon,  accrued fees and
all other  amounts  payable to it hereunder  and under the other Loan  Documents
(including  any amounts  under Section 3(g)) from the assignee (to the extent of
such outstanding principal and accrued interest and fees) or the Company (in the
case of all other amounts); and

          (iii)  such assignment does not conflict with applicable law.

          A Bank shall not be required to make any such assignment or delegation
if, prior thereto, such Bank consents to the Extension Request.

     2.   FEES.

          a.     CERTAIN FEES

          The Company  shall pay, or cause to be paid, to the Agent certain fees
set forth in the Fee Letter at the time  specified in the Fee Letter for payment
of such amounts.

          b.     FACILITY FEE

          The Company agrees to pay to the Banks a facility fee on the amount of
the Facility (whether or not used) at a rate per annum equal to the Facility Fee
Rate.  Such  facility fee shall be payable by the Company  quarterly on the 30th
day of each December, March, June and September after the date hereof and on the
Maturity Date as set forth in Section 1(c) hereof.

          c.     UTILIZATION FEE

          For each day the aggregate amount of Loans outstanding  exceeds 50% of
the  Commitments  as in  effect on such day,  the  Company  agrees to pay to the
Banks, in addition to any other amounts payable hereunder,  a utilization fee on
the aggregate outstanding amount of Loans on such date at a rate per annum equal
to the  Utilization  Fee Rate.  Such  utilization  fee shall be  payable  by the
Company  on the date  when the next  interest  payment  on such  Loans is due in
accordance  with Section  1(b) hereof and on the  Maturity  Date as set forth in
Section 1(c) hereof.

     3.   ADDITIONAL PROVISIONS RELATING TO LOANS.

          a.   INCREASED COST

          The Company agrees to reimburse each Bank for any increase in the cost
to such Bank of, or any  reduction in the amount of any sum  receivable  by such
Bank in respect of, making or maintaining  any Eurodollar  Loans  (including the
imposition,  modification or deemed  applicability of any reserves,  deposits or
similar requirements). The additional amount required to compensate any Bank for
such  increased  cost or reduced  amount shall be payable by the Company to such
Bank within five days of the Company's  receipt of written notice from such Bank
specifying  such  increased  cost or reduced  amount and the amount  required to
compensate  such Bank therefor,  which notice shall,  in the absence of manifest
error, be conclusive and binding on the Company.  In determining such additional
amount, a Bank may use reasonable averaging, attribution and allocation methods.

          b.     DEPOSITS  UNAVAILABLE  OR    INTEREST   RATE   UNASCERTAINABLE;
IMPRACTICABILITY

          If  the  Company has notified the  Agent  of  its intention  to borrow
          a  Eurodollar  Loan for an  Interest  Period and the Agent or any Bank
determines (which  determination shall be conclusive and binding on the Company)
that:

                      (1)  deposits of the  necessary  amount for such  Interest
          Period are not available to such Bank in the London  interbank  market
          or, by reason of  circumstances  affecting  such market,  adequate and
          reasonable means do not exist for ascertaining the Eurodollar Rate for
          such Interest Period; or

                      (2)  LIBOR will not adequately and fairly reflect the cost
          to the Bank of making or funding a Eurodollar  Loan for such  Interest
          Period; or

                      (3)  the making or funding of Eurodollar Loans has  become
          impracticable  as a result  of any event  occurring  after the date of
          this  Agreement  which,  in the  opinion of the Bank,  materially  and
          adversely affects such Loans or the interbank eurodollar market;

then any notice of a Eurodollar Loan previously given by the Company and not yet
borrowed shall be deemed to be a notice to make a Prime Rate Loan.

          c.     CHANGES IN LAW RENDERING EURODOLLAR LOANS UNLAWFUL

          If at  any time due to the adoption of, or change in, any  law,  rule,
regulation,  treaty or  directive  or in the  interpretation  or  administration
thereof by any court,  central  bank,  governmental  authority  or  governmental
agency charged with the  interpretation  or administration  thereof,  or for any
other reason arising  subsequent to the date hereof, it shall become (or, in the
good faith judgment of any Bank,  raise a substantial  question as to whether it
is) unlawful for such Bank to make or fund any Eurodollar Loan, Eurodollar Loans
shall not be made  hereunder



ALLETE, Inc.
January 11, 2006
Page 9

for the  duration of such  illegality.  If any such event shall make it unlawful
for any Bank to continue any Eurodollar  Loans  previously made by it hereunder,
the Company  shall,  after being notified by such Bank of the occurrence of such
event,  on such date as shall be specified in such notice,  either  convert such
Eurodollar  Loan to a Prime  Rate Loan or prepay in full such  Eurodollar  Loan,
together with accrued interest  thereon,  without any premium or penalty (except
as provided in Section 3(g)).

          d.     DISCRETION OF THE BANKS AS TO MANNER OF FUNDING

          Each Bank shall be entitled to fund and maintain its funding of all or
          any part of the Loans in any manner it sees fit; it being  understood,
however,  that for purposes of this Note, all determinations  hereunder shall be
made as if such Bank had actually  funded and maintained  each  Eurodollar  Loan
during the  Interest  Period for such  Eurodollar  Loan  through the purchase of
deposits  having a term  corresponding  to such  Interest  Period and bearing an
interest rate equal to LIBOR for such Interest Period.

          e.     TAXES

          All payments by  the  Company of  principal of, and  interest on,  the
          Loans and all other amounts  payable  hereunder shall be made free and
clear of and without deduction for any present or future income,  excise,  stamp
or franchise taxes and other taxes, fees, duties,  withholdings or other charges
of  any  nature  whatsoever  imposed  by any  taxing  authority,  but  excluding
franchise taxes and taxes imposed on or measured by each  respective  Bank's net
income or receipts  (such  non-excluded  items  being  called  "TAXES").  If any
withholding or deduction from any payment to be made by the Company hereunder is
required  in  respect  of any Taxes  pursuant  to any  applicable  law,  rule or
regulation, then the Company will

                 i.   pay  directly  to  the  relevant authority the full amount
          required to be so withheld or deducted;

                 ii.  promptly forward to each Bank an official receipt or other
          documentation  satisfactory  to such Bank  evidencing  such payment to
          such authority; and

                 iii. pay to  each  Bank such additional amount or amounts as is
          necessary to ensure that the net amount actually received by such Bank
          will equal the full amount such Bank would have  received  had no such
          withholding or deduction been required.

Moreover,  if any Taxes are directly asserted against any Bank or on any payment
received  by such Bank  hereunder,  such Bank may pay such Taxes and the Company
will promptly pay such  additional  amount  (including any penalty,  interest or
expense)  as is  necessary  in order that the net amount  received  by such Bank
after the payment of such Taxes (including any Taxes on such



ALLETE, Inc.
January 11, 2006
Page 10

additional  amount)  shall equal the amount such Bank would have received had no
such Taxes been asserted.

          If the  Company  fails to pay any  Taxes  when due to the  appropriate
taxing  authority or fails to remit to any Bank the  required  receipts or other
required  documentary  evidence,  the Company shall  indemnify such Bank for any
incremental  Tax,  interest,  penalty or expense that may become payable by such
Bank as a result of any such failure.

          f.     INCREASED CAPITAL COSTS

          If   any  change in, or  the  introduction, adoption,   effectiveness,
interpretation,   reinterpretation  or  phase-in  of,  any  law  or  regulation,
directive,  guideline,  decision or request  (whether or not having the force of
law) of any court,  central  bank,  regulator  or other  governmental  authority
affects  or would  affect  the  amount of capital  required  or  expected  to be
maintained  by any Bank or any  entity  controlling  any  Bank,  and  such  Bank
determines (in its sole and absolute  discretion) that the rate of return on its
or such controlling  entity's capital as a consequence of the Loans made by such
Bank or the  commitment  hereunder  is reduced to a level  below that which such
Bank or such  controlling  entity could have achieved but for the  occurrence of
any such circumstance,  then, in any such case, upon notice from time to time by
any Bank to the Company, the Company shall immediately pay directly to such Bank
additional amounts sufficient to compensate such Bank or such controlling entity
for such  reduction  in rate of return.  A statement  of any Bank as to any such
additional  amount or amounts  (including  calculations  thereof  in  reasonable
detail) shall,  in the absence of manifest  error,  be conclusive and binding on
the Company. In determining such amount, each Bank may use reasonable averaging,
attribution and allocation methods.

          g.     FUNDING LOSSES

          The Company will indemnify the Banks upon demand  against any loss  or
expense which any Bank may sustain or incur (including,  without limitation, any
loss or expense  sustained or incurred in  obtaining,  liquidating  or employing
deposits or other  funds  acquired  to effect,  fund or maintain  any Loan) as a
consequence  of (i) any failure of the  Company to make any payment  when due of
any amount due hereunder,  (ii) any failure of the Company to borrow a Loan on a
date specified therefor in a notice thereof, or (iii) any payment (including any
payment  upon  any  Bank's  acceleration  of the  Loans)  or  prepayment  of any
Eurodollar  Loan on a date  other than the last day of the  Interest  Period for
such Loan.

          the Banks may conclusively rely until it shall have received a further

          canceling or amending such prior certificate.

                 ii.  Each Bank shall  have received  its  respective  Note duly

occurred and be  continuing,  PROVIDED that this  subsection  4(b)(ii) shall not
apply to an Event of Default  occurring  solely under clause (vii) of subsection

exclusively  to repay the Company's  commercial  paper (and, in the event of any
such Loan, the Agent may require the Company to deliver  information  sufficient
to disburse the proceeds of such Loan directly to the holders of such commercial
paper or a paying agent therefor).

          Each  request  for a Loan  shall  be  deemed a  representation  by the
Company, as to the matters set forth in this Section.

          c.     CONDITIONS PRECEDENT TO FACILITY INCREASE

          The  effectiveness  of  any  increase  in  the  aggregate  Commitments

          The execution and delivery of this  Agreement,  the Note and the other
Loan Documents and the performance by the Company of its  obligations  hereunder
and thereunder are within the Company's  powers and have been duly authorized by
all necessary  action on the Company's  part, and do not and will not contravene

          Any  Bank  may at  any  time  grant  to one or  more  banks  or  other
institutions (each a "PARTICIPANT") participating interests in its Commitment or
any or all of  its  Loans.  In the  event  of  any  such  grant  by a Bank  of a
participating  interest  to a  Participant,  whether  or not upon  notice to the
Company  and the  Agent,  such Bank  shall  remain  solely  responsible  for the
performance of its  obligations  hereunder,  and the Company and the Agent shall
continue  to deal solely and  directly  with such Bank in  connection  with such
Bank's rights and obligations  under this Agreement.  Any agreement  pursuant to
which any Bank may grant such a  participating  interest shall provide that such
Bank shall retain the sole right and  responsibility  to enforce the obligations
of the Company hereunder including, without limitation, the right to approve any
amendment,  modification  or  waiver of any  provision  of this  Agreement.  The
Company  agrees  that each  Participant  shall,  to the extent  provided  in its
participation  agreement,  be entitled to the benefits of Section 3 with respect
to its participating interest.

          o.     ASSIGNMENTS

          Any  Bank  may at any  time  assign  to one or  more  banks  or  other
financial institutions (each an "ASSIGNEE") all, or a proportionate part of all,
of its  rights and  obligations  under this  Agreement  and the Notes,  and such
Assignee  shall  assume  such  rights  and  obligations,  pursuant  to a Joinder
Agreement  in  substantially  the  form of  Exhibit  B hereto  executed  by such
Assignee and such transferor Bank, with (and subject to) the subscribed  consent
of the Company,  which shall not be unreasonably  withheld, and the Agent, which
shall not be unreasonably withheld; PROVIDED that if an Assignee is an affiliate
of such transferor Bank or was a Bank immediately  prior to such assignment,  no
such consent of the Company  shall be required;  and PROVIDED  FURTHER  that, if
such assignment is in respect of a proportionate  part of the transferor  Bank's
rights and obligations  hereunder and under the Notes, the amount of such Bank's
Commitment  (together with the Commitment of any affiliate of such Bank),  after
taking into account such assignment,  is at least an amount equal to $5,000,000.
Upon  execution and delivery of such  instrument and payment by such Assignee to
such  transferor  Bank of an amount equal to the purchase  price agreed  between
such transferor  Bank and such Assignee,  such Assignee shall be a Bank party to
this  Agreement and shall have all the rights and  obligations  of a Bank with a
Commitment as set forth in such  instrument of  assumption,  and the  transferor
Bank shall be released from its obligations hereunder to a corresponding extent,
and no  further  consent  or  action by any party  shall be  required.  Upon the
consummation of any assignment  pursuant to this Subsection 9(o), the transferor
Bank, the Agent and the Company shall make appropriate  arrangements so that, if
required,  a new Note is issued to the  Assignee.  In  connection  with any

such  assignment,  the transferor Bank shall pay to the Agent an  administrative
fee for processing such assignment in the amount of $3,500.

          p.     FEDERAL RESERVE BANKS

          Any Bank may at any time assign all or any portion of its rights under
this  Agreement  and its Note to one or more of the Federal  Reserve Banks which
comprise  the Federal  Reserve  System.  No such  assignment  shall  release the
transferor Bank from its obligations hereunder.

          q.     IDENTITY OF HOLDERS

          The Agent and the Company  may,  for all  purposes of this  Agreement,
treat any Bank as the  holder of any Note  drawn to its order  (and owner of the
Loans evidenced  thereby) until written notice of assignment,  participation  or
other transfer shall have been received by them.

          r.     SPLIT-RATINGS

          In the event the Company's  S&P Rating and Moody's  Rating do not fall
within the same Level Status,  then (1) if the S&P Rating's Level Status and the
Moody's Rating's Level Status are in consecutive  Level Status  categories,  the
lower Level Status  shall be deemed to apply for  purposes of this  Agreement or
(2) if the S&P Rating's  Level Status and the Moody's  Rating's Level Status are
not in consecutive Level Status  categories,  then the Level Status  immediately
above the lower of the S&P Rating's Level Status and the Moody's  Rating's Level
Status shall be deemed to apply for purposes of this Agreement.  For purposes of
this  Agreement,  Level I Status  shall be deemed the highest and Level V Status
shall be deemed the lowest.

          s.     CONTINUED EFFECT; NO NOVATION

          Notwithstanding  anything  contained  herein,  this  Agreement  is not
intended to and does not serve to effect a novation of the Obligations. Instead,
it is the express  intention of the parties hereto to reaffirm the  indebtedness
which is outstanding as of the date hereof created under the Existing  Committed
Facility Letter which is evidenced by the notes provided for therein.

          t.     ADDITIONAL LENDERS

          The  Company  may,  upon the  approval  of the Agent,  add  additional
lenders as Banks hereto (each a "NEW BANK"), PROVIDED that if as a result of the
addition  of any New Bank the  aggregate  amount of  Commitments  then in effect
would exceed  $200,000,000,  the  approval of the  Required  Banks shall also be
required  prior to adding  any such New  Bank.  Costs  incurred  by the Agent in
connection with adding any New Bank shall be paid by the Company,  and the



ALLETE, Inc.

Page 29

legal documentation pursuant to which any New Bank is added shall be in form and
substance reasonably satisfactory to the Agent.

          u.     CUSTOMER IDENTIFICATION - USA PATRIOT ACT NOTICE.

          Each Bank (including  Agent) hereby notifies the Company that pursuant
to the  requirements of the PATRIOT Act, and such Bank's policies and practices,
such Bank is  required  to obtain,  verify and record  certain  information  and
documentation that identifies the Company and its affiliates,  which information
includes  the name and  address  of the  Company  or  affiliate  and such  other
information that will allow such Bank to identify the Company and its affiliates
in accordance with the PATRIOT Act.

     10.  THE AGENT.

          a.     APPOINTMENT AND AUTHORIZATION

          Each Bank  irrevocably  appoints and authorizes the Agent to take such
action as agent on its behalf and to exercise  such powers under this  Agreement
and the Notes as are  delegated  to the Agent by the  terms  hereof or  thereof,
together with all such powers as are reasonably incidental thereto.

          b.     AGENT'S FEE

          The  Company  shall pay to the Agent for its own  account  fees in the
amounts  and at the times  previously  agreed  upon  between the Company and the
Agent.

          c.     AGENT AND AFFILIATES

          LaSalle  Bank  National  Association  shall  have the same  rights and
powers  under this  Agreement as any other Bank and may exercise or refrain from
exercising  the same as though it were not the Agent,  and LaSalle Bank National
Association  and its  affiliates may accept  deposits  from,  lend money to, and
generally  engage in any kind of business  with the Company or  affiliate of the
Company as if it were not the Agent hereunder.

          d.     ACTION BY AGENT

          The  obligations of the Agent  hereunder are only those  expressly set
forth herein. Without limiting the generality of the foregoing,  the Agent shall
not be required to take any action with respect to any Event of Default,  except
as expressly  provided in Section 7(b). The Agent's  duties  hereunder and under
the other Loan  Documents are only those  expressly set forth herein and therein
and  nothing  herein  or  therein  shall be  deemed  to  impose on the Agent any
fiduciary obligation to any Bank or the Company.

          e.     CONSULTATION WITH EXPERTS

          The Agent may consult  with legal  counsel (who may be counsel for the
Company),  independent  public  accountants and other experts selected by it and
shall not be liable  for any  action  taken or omitted to be taken by it in good
faith in accordance with the advice of such counsel, accountants or experts.

          f.     LIABILITY OF AGENT

          Neither  the  Agent nor any of its  directors,  officers,  agents,  or
employees shall be liable to any Bank for any action taken or not taken by it in
connection herewith (i) with the consent or at the request of the Required Banks
or (ii) in the  absence  of its own  gross  negligence  or  willful  misconduct.
Neither the Agent nor any of its directors,  officers, agents or employees shall
be  responsible  to any Bank  for or have  any  duty to any  Bank to  ascertain,
inquire into or verify (i) any  statement,  warranty or  representation  made in
connection with this Agreement or any borrowing hereunder;  (ii) the performance
or observance  of any of the  covenants or agreements of the Company;  (iii) the
satisfaction of any condition  specified in Article III, except receipt of items
required to be delivered to the Agent;  (iv) the existence or  continuance of an
Event of Default;  or (iv) the validity,  effectiveness  or  genuineness of this
Agreement,  the  Notes,  the other Loan  Documents  or any other  instrument  or
writing  furnished  in  connection  herewith.  The  Agent  shall  not  incur any
liability  by  acting  in  reliance  upon  any  notice,  consent,   certificate,
statement, or other writing (which may be a bank wire, telex or similar writing)
believed  by it in good faith to be genuine or to be signed by the proper  party
or parties.

          g.     INDEMNIFICATION

          Each Bank shall, ratably in accordance with its Commitment,  indemnify
the Agent (to the  extent  not  reimbursed  by the  Company)  against  any cost,
expense (including counsel fees and disbursements),  claim, demand, action, loss
or liability (except such as result from the Agent's gross negligence or willful
misconduct) that the Agent may suffer or incur in connection with this Agreement
or any action taken or omitted by the Agent hereunder.

          h.     CREDIT DECISION

          Each Bank acknowledges that it has, independently and without reliance
upon the Agent or any other Bank, and based on such documents and information as
it has deemed  appropriate,  made its own credit  analysis and decision to enter
into this Agreement. Each Bank also acknowledges that it will, independently and
without  reliance upon the Agent or any other Bank,  and based on such documents
and information as it shall deem  appropriate at the time,  continue to make its
own credit decisions in taking or not taking any action under this Agreement.

          i.     SUCCESSOR AGENT

          The Agent may resign at any time by giving  written  notice thereof to
the Banks and the Company.  Upon any such resignation,  the Required Banks shall
have the right to appoint a  successor  Agent,  which  successor  Agent shall be
satisfactory to the Company.  If no successor Agent shall have been so appointed
by the Required Banks, and shall have accepted such appointment,  within 30 days
after the retiring  Agent gives notice of  resignation,  then the retiring Agent
may,  on behalf  of the  Banks,  appoint a  successor  Agent,  which  shall be a
commercial  bank  organized or licensed  under the laws of the United  States of
America or of any State thereof and having a combined  capital and surplus of at
least $100,000,000 and shall otherwise be subject to the consent of the Company,
which consent shall not be  unreasonably  withheld.  Upon the  acceptance of its
appointment as Agent hereunder by a successor Agent,  such successor Agent shall
thereupon  succeed  to and become  vested  with all the rights and duties of the
retiring  Agent,  and the retiring Agent shall be discharged from its duties and
obligations  hereunder.  After any  retiring  Agent's  resignation  hereunder as
Agent,  the  provisions  of this  Article  shall  inure to its benefit as to any
actions taken or omitted to be taken by it while it was Agent.
