Exhibit 10(c)

                               GUARANTY AGREEMENT

                                   GUARANTY AGREEMENT dated as of June 30, 2003,
                         among ADESA CORPORATION,  an Indiana  corporation,  and
                         ALLETE,    INC.,   a   Minnesota    corporation   (each
                         individually,  a  "GUARANTOR"  and  collectively,   the
                         "GUARANTORS") of ADESA  CALIFORNIA,  INC., a California
                         corporation  (the  "BORROWER"),  and  SUNTRUST  BANK, a
                         Georgia  banking  corporation as  administrative  agent
                         (the  "ADMINISTRATIVE   AGENT")  for  the  Lenders  (as
                         defined in the Credit Agreement referred to below).

               Reference is made to the Term Loan Agreement dated as of June 30,
2003 (as amended,  supplemented  or otherwise  modified  from time to time,  the
"CREDIT  AGREEMENT"),  among the  Borrower,  the lenders from time to time party
thereto (the  "LENDERS")  and SunTrust  Bank,  as  administrative  agent for the
Lenders  (in  such  capacity,  the  "ADMINISTRATIVE   AGENT"),   joined  by  the
Guarantors.  Capitalized terms used herein and not defined herein shall have the
meanings assigned to such terms in the Credit Agreement.

               The  Lenders  have  agreed  to make  Term  Loans to the  Borrower
pursuant to, and upon the terms and subject to the conditions  specified in, the
Credit Agreement.  The Borrower is the direct  wholly-owned  Subsidiary of ADESA
Corporation  ("ADESA") which, in turn, is an indirect Subsidiary of ALLETE, Inc.
("ALLETE"),  and accordingly,  each of the Guarantors  acknowledges that it will
derive substantial benefit from the making of the Term Loans by the Lenders. The
obligations  of the  Lenders to make the Term Loans are  conditioned  on,  among
other  things,  the  execution  and  delivery  by the  Guarantors  of a Guaranty
Agreement in the form hereof.  As consideration  therefor and in order to induce
the Lenders to make the Term Loans,  the  Guarantors are willing to execute this
Guaranty Agreement.

               Accordingly, the parties hereto agree as follows:

               SECTION 1. GUARANTEE. Each Guarantor unconditionally  guarantees,
jointly with the other  Guarantors and severally,  as a primary  obligor and not
merely as a surety, (a) the due and punctual payment of (i) the principal of and
premium,  if any, and interest  (including interest accruing during the pendency
of  any  bankruptcy,  insolvency,  receivership  or  other  similar  proceeding,
regardless  of whether  allowed or  allowable  in such  proceeding)  on the Term
Loans, when and as due, whether at maturity,  by acceleration,  upon one or more
dates set for prepayment or otherwise,  and (ii) all other monetary obligations,
including fees,  costs,  expenses and indemnities,  whether primary,  secondary,
direct, contingent,  fixed or otherwise (including monetary obligations incurred
during the pendency of any bankruptcy, insolvency, receivership or other similar
proceeding,  regardless of whether allowed or allowable in such proceeding),  of
the Loan Parties to the  Administrative  Agent and the Lenders  under the Credit
Agreement and the other Loan Documents,  (b) the due and punctual performance of
all covenants, agreements, obligations and liabilities of the Loan Parties under
or pursuant to the Credit  Agreement and the other Loan  Documents;  and (c) the
due and punctual  payment and  performance  of all  obligations of the Borrower,
monetary  or  otherwise,  under  each  Hedging  Agreement  entered  into  with a
counterparty  that was a Lender  or an  Affiliate  of a Lender  at the time such
Hedging  Agreement  was entered  into (all the  monetary  and other  obligations
referred to in the preceding clauses (a) through (c) being  collectively  called
the  "OBLIGATIONS").  Each Guarantor  further agrees that the Obligations may be
extended or renewed,  in whole or in part (but the principal amount of the Notes
may not be increased),  without notice to or further assent from it, and that it
will remain bound upon its guarantee notwithstanding any extension or renewal of
any Obligation.

               SECTION 2.  OBLIGATIONS   NOT  WAIVED.   To  the  fullest  extent
permitted by applicable  law, each Guarantor  waives  presentment  to, demand of
payment  from and protest to the  Borrower of any of the  Obligations,  and also
waives  notice  of  acceptance  of its  guarantee  and  notice  of  protest  for
nonpayment.  To the fullest extent  permitted by applicable law, the obligations
of each  Guarantor  hereunder  shall not be  affected  by (a) the failure of the
Administrative  Agent or any  Lender to assert any claim or demand or to enforce
or  exercise  any right or remedy  against the  Borrower or any other  Guarantor
under the  provisions  of the  Credit  Agreement,  any other  Loan  Document  or
otherwise,  (b) any rescission,  waiver,  amendment or  modification  of, or any
release from any of the terms or provisions of, this  Agreement,  any other Loan
Document or any other  agreement,  including with respect to any other Guarantor
under this Agreement, or (c) the failure to perfect any security interest in, or
the release of, any of the security  held by or on behalf of the  Administrative
Agent or any Lender.




               SECTION 3.  SECURITY.  Each  of  the  Guarantors  authorizes  the
Administrative  Agent  and  each of the  Lenders,  from  time  to time at  their
discretion  and without  notice to  Guarantors  (but subject to the terms of the
other  Loan  Documents),  to take any or all of the  following  actions  without
impairing the Guarantors' obligations hereunder:  (a) retain or obtain a lien on
or security  interest in any  property to secure any of the  Obligations  or any
liability or obligation hereunder; (b) retain or obtain the primary or secondary
obligation  of any obligor or  obligors,  in addition  to the  Guarantors,  with
respect to any of the  Obligations;  (c) extend or renew for one or more periods
(regardless  of  whether  longer  than  the  original  period),  or  release  or
compromise any  obligation of the Guarantors  hereunder or any obligation of any
nature of any other obligor (including,  without limitation,  the Borrower) with
respect to any of the Obligations: (d) release or fail to perfect its lien on or
security interest in, or impair,  surrender,  release or permit any substitution
or exchange for, all or any part of any property securing any of the Obligations
or any  liability or  obligation  hereunder,  or extend or renew for one or more
periods  (regardless of whether  longer than the original  period) or release or
compromise any obligations of any nature of any obligor with respect to any such
property,  or apply any such  property  and  direct  the order or manner of sale
thereof  as they,  in their  sole  discretion,  may  determine;  (e)  release or
substitute any one or more endorsees,  other  guarantors of other obligors;  and
(f)  resort  to the  Guarantors,  or  either  of them,  for  payment  of any the
Obligations,  regardless of whether the Administrative Agent or any other Person
shall have  resorted to any  property  securing  any of the  Obligations  or any
liability or obligation  hereunder or shall have proceeded  against the Borrower
or any other obligator primarily or secondarily obligated with respect to any of
the Obligations  (all of the actions referred to in this clause (f) being hereby
expressly waived by the Guarantors).

               SECTION 4.  GUARANTEE OF PAYMENT. Each  Guarantor  further agrees
that  its  guaranty  constitutes  a  guarantee  of  payment  when due and not of
collection,  and  waives  any  right to  require  that any  resort be had by the
Administrative  Agent or any Lender to any of the  security  held for payment of
the  Obligations or to any balance of any deposit account or credit on the books
of the Administrative  Agent or any Lender in favor of the Borrower or any other
Person.

               SECTION 5.  NO  DISCHARGE  OR   DIMINISHMENT  OF  GUARANTEE.  The
obligations of each Guarantor  hereunder  shall not be subject to any reduction,
limitation,   impairment  or   termination   for  any  reason  (other  than  the
indefeasible payment in full in cash of the Obligations), including any claim of
waiver, release, surrender,  alteration or compromise of any of the Obligations,
and shall not be subject to any defense or setoff,  counterclaim,  recoupment or
termination   whatsoever   by   reason   of  the   invalidity,   illegality   or
unenforceability   of  the  Obligations  or  otherwise.   Without  limiting  the
generality of the foregoing,  the obligations of each Guarantor  hereunder shall
not be  discharged  or  impaired  or  otherwise  affected  by the failure of the
Administrative  Agent or any  Lender to assert any claim or demand or to enforce
any remedy  under the Credit  Agreement,  any other Loan  Document  or any other
agreement, by any waiver or modification of any provision of any thereof, by any
default,  failure or delay,  willful or  otherwise,  in the  performance  of the
Obligations,  or by any other act or omission that may or might in any manner or
to the extent vary the risk of any Guarantor or that would otherwise  operate as
a  discharge  of each  Guarantor  as a matter of law or equity  (other  than the
indefeasible payment in full in cash of all the Obligations).

               SECTION 6.  DEFENSES OF BORROWER  WAIVED.  To the fullest  extent
permitted by  applicable  law,  each  Guarantor  waives any defense  based on or
arising  out of any  defense  of the  Borrower  or the  unenforceability  of the
Obligations or any part thereof from any cause,  or the cessation from any cause
of the liability of the Borrower,  other than the final and indefeasible payment
in full in cash of the  Obligations.  The  Administrative  Agent and the Lenders
may, at their election, foreclose on any security held by one or more of them by
one or more  judicial or  nonjudicial  sales,  accept an  assignment of any such
security  in  lieu  of  foreclosure,  compromise  or  adjust  any  part  of  the
Obligations,  make any  other  accommodation  with  the  Borrower  or any  other
guarantor,  without  affecting  or  impairing  in any way the  liability  of any
Guarantor  hereunder  except to the  extent  the  Obligations  have been  fully,
finally  and  indefeasibly  paid in  cash.  Pursuant  to  applicable  law,  each
Guarantor  waives any defense  arising out of any such election even though such
election  operates,  pursuant to applicable  law, to impair or to extinguish any
right of reimbursement or subrogation or other right or remedy of such Guarantor
against the Borrower or any other Guarantor or guarantor, as the case may be, or
any security.

               SECTION 7. AGREEMENT TO PAY; SUBORDINATION. In furtherance of the
foregoing and not in limitation of any other right that the Administrative Agent
or any Lender has at law or in equity  against any  Guarantor by virtue  hereof,
upon the failure of the  Borrower or any other Loan Party to pay any  Obligation
when




and as the same shall become due, whether at maturity,  by  acceleration,  after
notice of prepayment or otherwise,  each Guarantor  hereby  promises to and will
forthwith pay, or cause to be paid, to the Administrative  Agent for the benefit
of the Lenders in cash the amount of such unpaid  Obligations.  Upon  payment by
any  Guarantor  of any sums to the  Administrative  Agent,  all  rights  of such
Guarantor  against the Borrower  arising as a result  thereof by way of right of
subrogation,  contribution,  reimbursement,  indemnity or otherwise shall in all
respects be subordinate and junior in right of payment to the prior indefeasible
payment in full in cash of all the Obligations. In addition, any indebtedness of
the Borrower now or hereafter  held by any Guarantor is hereby  subordinated  in
right of payment to the prior payment in full in cash of the Obligations. If any
amount  shall  erroneously  be paid to any  Guarantor  on  account  of (i)  such
subrogation, contribution, reimbursement, indemnity or similar right or (ii) any
such  indebtedness  of the Borrower,  such amount shall be held in trust for the
benefit of the Administrative  Agent and the Lenders and shall forthwith be paid
to  the  Administrative  Agent  to  be  credited  against  the  payment  of  the
Obligations,  whether matured or unmatured,  in accordance with the terms of the
Loan Documents.

               SECTION 8. INFORMATION. Each Guarantor assumes all responsibility
for being and keeping itself informed of the Borrower's  financial condition and
assets,  and of all other  circumstances  bearing upon the risk of nonpayment of
the  Obligations  and the  nature,  scope  and  extent  of the  risks  that such
Guarantor   assumes  and  incurs   hereunder,   and  agrees  that  none  of  the
Administrative  Agent or the  Lenders  will have any duty to  advise  any of the
Guarantors  of   information   known  to  it  or  any  of  them  regarding  such
circumstances or risks.

               SECTION 9.   REPRESENTATIONS  AND  WARRANTIES.   Each   Guarantor
represents  and warrants as to itself that all  representations  and  warranties
relating to it contained in the Credit Agreement are true and correct.

               SECTION 10. TERMINATION.  The guarantees made hereunder (a) shall
terminate when all the Obligations  have been paid in full in cash and satisfied
and (b) shall continue to be effective or be reinstated,  as the case may be, if
at any time payment, or any part thereof, of any Obligation is rescinded or must
otherwise  be restored by any Lender or any  Guarantor  upon the  bankruptcy  or
reorganization of the Borrower,  any Guarantor or otherwise.  In connection with
the  foregoing,  the  Administrative  Agent  shall  execute  and deliver to such
Guarantor or Guarantor's designee, at such Guarantor's expense, any documents or
instruments  which such Guarantor shall reasonably  request from time to time to
evidence such termination and release.

               SECTION 11.  BINDING   EFFECT;  SEVERAL  AGREEMENT;  ASSIGNMENTS.
Whenever  in this  Agreement  any of the  parties  hereto is  referred  to, such
reference  shall be deemed to include the  successors and assigns of such party;
and all  covenants,  promises and  agreements by or on behalf of the  Guarantors
that are contained in this Agreement shall bind and inure to the benefit of each
party hereto and their respective  successors and assigns.  This Agreement shall
become  effective as to any  Guarantor  when a  counterpart  hereof  executed on
behalf of such Guarantor shall have been delivered to the Administrative  Agent,
and  a   counterpart   hereof  shall  have  been   executed  on  behalf  of  the
Administrative  Agent,  and thereafter  shall be binding upon such Guarantor and
the Administrative Agent and their respective  successors and assigns, and shall
inure  to the  benefit  of such  Guarantor,  the  Administrative  Agent  and the
Lenders, and their respective  successors and assigns,  except that no Guarantor
shall  have the  right to assign  its  rights or  obligations  hereunder  or any
interest  herein (and any such attempted  assignment  shall be void);  PROVIDED,
HOWEVER,  that if ALLETE is a party to an  internal  reorganization  pursuant to
which all or  substantially  all of ALLETE'S  common stock is exchanged  for the
common stock of an entity that becomes  ALLETE'S  parent,  ALLETE may assign and
delegate  its rights and  obligations  under this  Guaranty to its new parent so
long as (a)  such  new  parent  is at  least  of the  same  credit  quality  (as
reasonably  determined  by the  Lenders)  as  ALLETE  immediately  prior to such
reorganization   and  (b)  such  new  parent   executes   and  delivers  to  the
Administrative  Agent such assumption  agreements,  certificates and opinions as
the  Administrative  Agent  reasonably  requests.  Upon any such  delegation and
assumption of obligations in accordance with the previous sentence,  ALLETE, but
not  ADESA,  shall be  relieved  of and fully  discharged  from all  obligations
hereunder,  whether such  obligations  arose before or after such delegation and
assumption.  This  Agreement  shall be  construed as a separate  agreement  with
respect to each Guarantor and may be amended, modified, supplemented,  waived or
released  with  respect  to any  Guarantor  without  the  approval  of any other
Guarantor  and  without   affecting  the  obligations  of  any  other  Guarantor
hereunder.




               SECTION 12. WAIVERS; AMENDMENT.

               (a)     No failure or delay of the Administrative Agent of any in
exercising any power or right hereunder  shall operate as a waiver thereof,  nor
shall  any  single  or  partial  exercise  of any such  right or  power,  or any
abandonment  or  discontinuance  of steps  to  enforce  such a right  or  power,
preclude  any other or further  exercise  thereof or the  exercise  of any other
right or power. The rights and of the Administrative  Agent hereunder and of the
Lenders under the other Loan  Documents are  cumulative and are not exclusive of
any  rights  or  remedies  that  they  would  otherwise  have.  No waiver of any
provision  of this  Agreement  or  consent  to any  departure  by any  Guarantor
therefrom shall in any event be effective  unless the same shall be permitted by
paragraph (b) below, and then such waiver and consent shall be effective only in
the specific  instance and for the purpose for which given.  No notice or demand
on any  Guarantor  in any case  shall  entitle  such  Guarantor  to any other or
further notice in similar or other circumstances.

               (b)     Neither this Agreement nor any  provision  hereof  may be
waived,  amended or modified except pursuant to a written agreement entered into
between  the  Guarantors  with  respect  to  which  such  waiver,  amendment  or
modification  relates  and the  Administrative  Agent,  with the  prior  written
consent of the  Required  Lenders  (except as  otherwise  provided in the Credit
Agreement).

               SECTION 13.  GOVERNING LAW. THIS AGREEMENT  SHALL BE GOVERNED BY,
AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF FLORIDA.

               SECTION 14. NOTICES.  All  communications  and notices  hereunder
shall be in  writing  and  given  as  provided  in  Section  10.1 of the  Credit
Agreement.  All  communications and notices hereunder to each Guarantor shall be
given to it at its address set forth in Section 10.1 of the Credit Agreement.

               SECTION 15. SURVIVAL OF AGREEMENT; SEVERABILITY.

               (a)     All covenants, agreements  representations and warranties
made by the  Guarantors  herein  and in the  certificates  or other  instruments
prepared or delivered in  connection  with or pursuant to this  Agreement or the
other  Loan  Document  shall  be  considered  to have  been  relied  upon by the
Administrative Agent and the Lenders and shall survive the making by the Lenders
of the Term  Loans  regardless  of any  investigation  made by any of them or on
their  behalf,  and  shall  continue  in full  force  and  effect as long as the
principal of or any accrued interest on any Term Loan or any other fee or amount
payable  under this  Agreement  or any other Loan  Document is  outstanding  and
unpaid.

               (b)     In  the event one or more of the provisions  contained in
this Agreement or in any other Loan Document should be held invalid,  illegal or
unenforceable in any respect,  the validity,  legality and enforceability of the
remaining  provisions  contained  herein  and  therein  shall  not in any way be
affected  or impaired  thereby (it being  understood  that the  invalidity  of a
particular  provision  in a particular  jurisdiction  shall not in and of itself
affect the validity of such  provision in any other  jurisdiction).  The parties
shall  endeavor in good-faith  negotiations  to replace the invalid,  illegal or
unenforceable  provisions  with valid  provisions  the economic  effect of which
comes as close as  possible  to that of the  invalid,  illegal or  unenforceable
provisions.

               SECTION 16.  COUNTERPARTS.  This  Agreement  may  be  executed in
counterparts,  each of which shall constitute an original, but all of which when
taken together shall  constitute a single contract  (subject to Section 11), and
shall  become  effective  as  provided  in Section  11.  Delivery of an executed
signature page to this Agreement by facsimile transmission shall be as effective
as delivery of a manually executed counterpart of this Agreement.

               SECTION 17. RULES OF INTERPRETATION.  The rules of interpretation
specified in Section 1.03 of the Credit  Agreement  shall be  applicable to this
Agreement.

               SECTION 18. JURISDICTION; CONSENT TO SERVICE OF PROCESS.

               (a)  Each  Guarantor  hereby   irrevocably  and   unconditionally
submits,  for itself and its property,  to the nonexclusive  jurisdiction of any
Florida state court or Federal court of the United States of America

{OR641843;1}



sitting in Orlando,  Florida,  and any appellate court from any thereof,  in any
action or proceeding  arising out of or relating to this  Agreement or the other
Loan Documents,  or for recognition or enforcement of any judgment,  and each of
the parties hereto hereby irrevocably and unconditionally agrees that all claims
in respect of any such action or proceeding  may be heard and determined in such
Florida state court or, to the extent  permitted by law, in such Federal  court.
Each of the parties  hereto  agrees that a final  judgment in any such action or
proceeding  shall be conclusive  and may be enforced in other  jurisdictions  by
suit on the  judgment or in any other  manner  provided by law.  Nothing in this
Agreement shall affect any right that the Administrative Agent or any Lender may
otherwise  have to bring any action or proceeding  relating to this Agreement or
the other Loan  Documents  against any Guarantor or its properties in the courts
of any jurisdiction.

               (b)     Each  Guarantor  hereby  irrevocably  and unconditionally
waives,  to the  fullest  extent  it may  legally  and  effectively  do so,  any
objection  that it may now or hereafter have to the laying of venue of any suit,
action or proceeding  arising out of or relating to this  Agreement or the other
Loan Documents in any Florida state or Federal court. Each of the parties hereto
hereby  irrevocably  waives, to the fullest extent permitted by law, the defense
of an inconvenient  forum to the maintenance of such action or proceeding in any
such court.

               (c)     Each  party  to  this  Agreement  irrevocably consents to
service of process in the manner  provided for notices in Section 14. Nothing in
this  Agreement  will affect the right of any party to this  Agreement  to serve
process in any other manner permitted by law.

               SECTION 19. WAIVER OF JURY TRIAL. EACH PARTY HERETO HERBY WAIVES,
TO THE FULLEST  EXTENT  PERMITTED BY APPLICABLE  LAW, ANY RIGHT IT MAY HAVE TO A
TRIAL BY JURY IN RESPECT OF ANY  LITIGATION  DIRECTLY OR INDIRECTLY  ARISING OUT
OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR THE OTHER LOAN DOCUMENTS. EACH
PARTY  HERETO (A)  CERTIFIES  THAT NO  REPRESENTATIVE,  AGENT OR ATTORNEY OF ANY
OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD
NOT, IN THE EVENT OF  LITIGATION,  SEEK TO ENFORCE THE FOREGOING  WAIVER AND (B)
ACKNOWLEDGES  THAT IT AND THE OTHER  PARTIES  HERETO HAVE BEEN  INDUCED TO ENTER
INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS, AS APPLICABLE, BY, AMONG OTHER
THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 19.

               SECTION 20.  RIGHT OF SETOFF.  If an Event of Default  shall have
occurred and be  continuing,  each Lender is hereby  authorized  at any time and
from time to time, to the fullest extent  permitted by law, to set off and apply
any and all deposits (general or special, time or demand,  provisional or final)
at any time held and other  Indebtedness  at any time owing by such Lender to or
for  the  credit  or  the  account  of any  Guarantor  against  any  or all  the
obligations of such Guarantor now or hereafter existing under this Agreement and
the other Loan  Documents  held by such Lender,  irrespective  of whether or not
such Person  shall have made any demand  under this  Agreement or any other Loan
Document and although  such  obligations  may be  unmatured.  The rights of each
Lender  under  this  Section 20 are in  addition  to other  rights and  remedies
(including other rights of setoff) which such Lender may have.
