                                PROXY STATEMENT

                  This Proxy Statement and accompanying proxy
         were first mailed to Shareholders on or about April 11, 2003

     This Proxy Statement is  furnished in connection  with the solicitation  of
proxies by  the Board  of  Directors of  Blackhawk  Bancorp, Inc.,  a  Wisconsin
corporation (the "Corporation"), for  the annual meeting  of shareholders to  be
held on Wednesday, May 21, 2003 beginning at 10:00 A.M.

     Shareholders of record at the  close of business on  April 1, 2003 will  be
entitled to one vote on each matter presented for  each share so held.  At  that
date there were  2,517,131 shares of  Common Stock outstanding  and entitled  to
vote at the meeting. Any shareholder entitled to vote may vote either in  person
or by  duly  authorized  proxy.    Shares  of  the  Corporation's  Common  Stock
represented by properly  executed proxies received  by the  Corporation will  be
voted at the meeting and any adjournment thereof in accordance with the terms of
such proxies, unless revoked. If no choice is specified, the proxy will be voted
in favor of the nominees listed in  Item 1, for ratification of the  appointment
of McGladrey & Pullen,  LLP as auditors for  2003 and in  the discretion of  the
proxy holder on any other matter which may properly come before the meeting  and
all adjournments or postponements of the meeting. Proxies may be revoked at  any
time prior  to  the voting  thereof  either by  written  notice filed  with  the
secretary or  the acting  secretary of  the meeting  or by  oral notice  to  the
presiding officer during  the meeting.   The  representation at  the meeting  in
person or by proxy of shareholders of the Corporation holding a majority of  the
Corporation's shares of Common Stock entitled to vote shall constitute a  quorum
for the transaction of business.  For the purpose of determining the presence of
a quorum,  shares represented  on any  matter  will be  counted as  present  and
represented on all matters to be  acted upon, including any matter with  respect
to which the holder  of such shares abstains  from voting, and including  shares
which are not voted by a holder of record who is a broker because the broker has
not received authority from the beneficial  owner, as required under  applicable
laws and rules, to vote the shares on such matter ("broker nonvotes").

     Directors are elected by a  plurality of the votes  cast by the holders  of
the Corporation's  Common Stock  at a  meeting  at which  a quorum  is  present.
"Plurality" means that the individuals who  receive the largest number of  votes
cast are elected as directors up to the maximum number of directors to be chosen
at the meeting.   Consequently,  any shares  not voted  (whether by  abstention,
broker nonvote or otherwise) have no impact on the election of directors  except
to the extent  that the failure  to vote for  an individual  results in  another
individual receiving a comparatively  larger number of  votes.  Under  Wisconsin
law, votes cast "AGAINST" a director nominee  are given no legal effect and  are
not counted as votes cast in the election of directors.

     Approval of  any other  matter which  properly  comes before  the  meeting,
including ratification of McGladrey & Pullen, LLP, will require the  affirmative
vote of a majority of the shares represented at the meeting and entitled to vote
on the particular matter.   In tabulating votes cast  on any such other  matter,
abstentions will be considered  votes cast, and accordingly  will have the  same
effect as a  negative vote.   Broker nonvotes, on  the other hand,  will not  be
counted as shares entitled to be  voted on the particular matter, and  therefore
will have no impact on the outcome of the vote.

     Expenses in connection with the solicitation of proxies will be paid by the
Corporation.  Upon  request, the  Corporation will  reimburse brokers,  dealers,
banks and voting trustees, or their  nominees, for reasonable expenses  incurred
in forwarding copies of the proxy  material and annual report to the  beneficial
owners of shares  which such persons  hold of record.   Solicitation of  proxies
will be principally by  mail.  Proxies may  also be solicited  in person, or  by
telephone, by  officers  and regular  employees  of the  Corporation,  who  will
receive no additional or special compensation  for their services.  Shares  held
for the accounts of participants in  the Corporation's Employee Stock  Ownership
Plan ("ESOP")  will  be  voted  in  accordance  with  the  instructions  of  the
participants or  otherwise in  accordance with  the terms  of the  ESOP.   Under
provisions of the  ESOP, if  no instructions  are received  from a  participant,
their shares cannot be voted.

                      BENEFICIAL OWNERSHIP OF SECURITIES

     The table below sets forth  information regarding the beneficial  ownership
of Common Stock of the Corporation, as  of March 14, 2003, by each director  and

Compensation Table, and by all nominees for director and individuals who  served
as directors and executive officers  of the Corporation on  March 14, 2003 as  a

vote of, or the power to dispose or  direct the disposition of, such shares,  or
who has  the right  to  acquire beneficial  ownership  thereof within  60  days.
Beneficial ownership for the purposes of this Proxy Statement is not necessarily
to be construed as an admission of beneficial ownership for other purposes.

                             ELECTION OF DIRECTORS

     The Corporation's Bylaws, and actions of the Board taken pursuant  thereto,
provide that there shall be 11  directors divided into three classes, as  nearly
equal in number as practicable, each to  serve 3-year staggered terms.  At  each
annual meeting the term of office of one of the three classes expires, and a new
class must be elected or re-elected to serve for a term of three years or  until
their successors are duly elected and qualified.

     The four nominees standing for election as directors of the Corporation  at
the 2003 annual meeting  are Mr. Kenneth A.  Hendricks, Mr. George D.  Merchant,
Mr. Stephen P. Carter and Mr. Stephen R.  Thomas for terms expiring at the  2006
annual meeting  of shareholders.   Mr.  Hendricks  has been  a director  of  the
Corporation since 1996.  Mr. Merchant  has been  a director  of the  Corporation
since  1989.  Messrs.  Carter  and  Thomas  have  been  nominated  to  fill  the
directorates of Messrs. Conerton and Puri, who will not stand for re-election at
the annual meeting. The Board thanks Mr. Conerton who has been a director  since
1989, for his many  years of dedicated  service to the  Corporation.  The  Board
also wishes to thank Mr. Puri, who has been a director since 2000, for his years
of dedicated service to the Corporation.

     The Board recommends that the shareholders elect the four nominees to serve
as directors  of the  Corporation for  a  term of  three  years or  until  their
successors have been  duly elected and  qualified.   Unless otherwise  directed,
proxies will be  voted for the  election of the  four nominees.   If any of  the
nominees should  decline  or be  unable  to act  as  a director,  which  is  not
foreseen, proxies may  be voted with  discretionary authority  for a  substitute
nominee designated by the Board of Directors.

MEETINGS AND COMMITTEES

     The Board of Directors held 13 meetings during 2002.  Each of the directors
attended at  least 75%  of the  meetings  of the  Board (including  meetings  of
committees of which the director is a member) held during the period of 2002 for
which he or she served as a director, except for Mr. Taylor who attended 50%  of
his meetings and resigned  as a director  effective May 15,  2002. There are  no
standing nomination or similar committees of the Board.

     The Corporation has  an Executive Committee,  of which Mr.  Howard was  the
chairman.  The other  members of the  Executive Committee are  set forth on  the
tables above.  The Executive Committee  is authorized to exercise the powers  of
the Board of  Directors in the  management of the  business and  affairs of  the
Corporation when the Board is not in session, except for those powers which  are
non-delegable by law or have been delegated to other committees.  The  Executive
Committee did not meet in 2002.

     The Corporation has  a Compensation  Committee of  which Mr.  Mott was  the
chairman. The other members of the  Compensation Committee are set forth on  the
tables above.    The Compensation  Committee reviews  and makes  recommendations
with respect to the Corporation's and  its subsidiary's hiring and  compensation
policies, and  performs  administrative  functions  with  respect  to  the  Cor-
poration's 1990  and  1994  Executive Stock  Option  Plans.    The  Compensation
Committee met 5 times in 2002.

     The Corporation has an Audit and Compliance Committee of which Mr. Merchant
was the chairman.  The other members  of the Audit and Compliance Committee  are
set forth on the tables above.  The Board of Directors believes that all of  the
current  members  of  the  Audit  and  Compliance  Committee  are   "independent
directors" as defined by  the listing standards of  the National Association  of
Securities Dealers, Inc.  The Audit and Compliance Committee's functions include
meeting  with  the  Corporation's  independent  public  accountants  and  making
recommendations to the Board of Directors regarding the engagement or  retention
of such  accountants,  adoption of  accounting  methods and  procedures,  public
disclosures required to comply with securities  laws and other matters  relating
to the  Corporation's financial  accounting.    The  Charter for  the Audit  and
Compliance Committee is attached as Annex I.  The Audit and Compliance Committee
met 11 times in 2002.

                     AUDIT AND COMPLIANCE COMMITTEE REPORT

     The Corporation's  Audit  and Compliance  Committee  is comprised  of  four
directors who are not officers of the Corporation.  The members of the Audit and
Compliance Committee are  independent as  defined by  Rule 4200(a)  (15) of  the
National Association of Securities Dealers' listing standards. A  responsibility
of the Committee is to monitor and review the Corporation's financial  reporting
process on behalf of the Board  of Directors. Management is responsible for  the
Corporation's internal controls  and the financial  reporting process while  the
independent accountants are responsible for  performing an independent audit  of
the Corporation's consolidated financial statements in accordance with generally
accepted auditing standards and to issue a report thereon.

     The Committee held eleven meetings during  2002.  One meeting was  designed
to facilitate and  encourage open communication  between the  Committee and  the
Corporation's prior independent public accountants, Wipfli Ullrich Bertleson LLP
("Wipfli"). During  the  meeting,  the  Committee  reviewed  and  discussed  the
Corporation's annual financial statements with management and Wipfli.

     On August  27,  2002  the  Audit  and  Compliance  Committee  approved  the
appointment of McGladrey & Pullen, LLP to serve as the Corporation's independent
public accountants for the year ended December 31, 2002. See "Other  Information
- Independent Auditors."

     The Audit and  Compliance Committee believes  that management maintains  an
effective system of internal controls that results in fairly presented financial
statements.  The   Committee  discussed   with   Wipfli  matters   relating   to
communications with  audit  committees  as required  by  Statement  on  Auditing
Standards No. 61.  Wipfli also provided to the Committee the written disclosures
relative to auditor  independence as  required by  Independence Standards  Board
Standard No.  1.   The Committee  also  reviewed a  list of  non-audit  services
performed during fiscal year 2002 and  determined, based upon their scope,  that
such services did not affect the independence of Wipfli and McGladrey &  Pullen,
LLP in performing their audit services.  Fees paid to and for the 2002 financial
statement audit performed by McGladrey & Pullen, LLP are as summarized under the
caption "Audit  and  Non-Audit  Fees".    The  Audit  and  Compliance  Committee
considered these  fees in  its  assessment of  the  independence of  Wipfli  and
McGladrey & Pullen, LLP and deemed that the services provided and the fees  paid
for  those  services  were  compatible  with  maintaining  independence  of  the
Corporation's independent public accountant.

     Based on these discussions, the Audit and Compliance Committee  recommended
to the Board of Directors that  the audited financial statements be included  in
the Corporation's Annual Report on Form  10-KSB for the year ended December  31,
2002.

Respectfully submitted  to  the  Corporation's shareholders  by  the  Audit  and
Compliance Committee of the Board of Directors.

                           COMPENSATION OF DIRECTORS

DIRECTORS' FEES

     Directors of the Corporation who are not employees of the Corporation or of
the Bank  receive a  $6,000 annual  retainer  and $250  for each  board  meeting
attended and  $100 for  each  committee meeting  attended.   Directors  who  are
employees received a quarterly retainer of  $1,750 through June 30, 2002.  After
that date employee directors no longer  receive any additional compensation  for
serving as a director. The Corporation  has also established stock option  plans
in which non-employee directors are eligible to participate.

DIRECTORS' STOCK OPTION PLANS

     Prior to its expiration on January 24, 1995, the Corporation maintained the
Blackhawk Bancorp, Inc. 1990 Directors' Stock Option Plan (the "1990  Directors'
Plan"), which  was  intended  to  provide an  incentive  for  directors  of  the
Corporation who are not  active full-time employees of  the Corporation or of  a
subsidiary  of  the  Corporation  ("Outside  Directors")  to  improve  corporate
performance on a long-term basis.  To replace the expired 1990 Directors'  Plan,
the Board  of Directors  adopted, and  the shareholders  of the  Corporation  on
May 11, 1994 approved, the Blackhawk Bancorp, Inc. 1994 Directors' Stock  Option
Plan (the  "1994  Directors'  Plan"), which  is  substantially  similar  in  all
material respects to  the 1990 Directors'  Plan.  The  1994 Directors' Plan  has
150,000 shares  of the  Corporation's Common  Stock  reserved for  issuance  and
provides for the granting of non-qualified stock options.

     On March 3,  2003, each  of the  ten  Outside Directors  automatically  was
granted an option under the 1994 Directors' Plan to purchase 2,000 shares of the
Corporation's Common Stock at a per share exercise price of $9.90 (the per share
market price of the Corporation's Common Stock on that date).  On March 1, 2002,
each of  the  ten Outside  Directors  automatically  was granted  an  option  to
purchase 2,000 shares at an  exercise price of $9.50,  the market price on  that
date.   Giving  effect to  those  grants, the  total  number of  shares  of  the
Corporation's Common Stock subject to outstanding grants under the 1990 and 1994
Directors' Plans as of March 14,  2003 was 81,850, and there remained  available
59,383 shares  for future  grants under  the  1994 Directors'  Plan.   The  1990
Directors' Plan expired on January 24, 1995; therefore, no more options will  be
granted under that  Plan.   The 1994 Directors'  Plan will  expire December  31,
2003.

EXECUTIVE STOCK OPTIONS

     Prior to its expiration on January 24, 1995, the Corporation maintained the
Blackhawk Bancorp, Inc. 1990  Executive Stock Option  Plan (the "1990  Executive
Plan"), which provided an incentive for executive officers of the Corporation or
any of its subsidiaries to improve  corporate performance on a long-term  basis.
To replace  the expired  1990 Executive  Plan,  the Board  of Directors  of  the
Corporation  adopted,  and  on  May 11,  1994  the  shareholders  approved,  the
Blackhawk Bancorp, Inc. 1994  Executive Stock Option  Plan (the "1994  Executive
Plan"), which is  substantially similar  in all  material respects  to the  1990
Executive Plan.  The 1994 Executive Plan provides for the granting of  incentive
stock options ("ISOs") intended to qualify as such within the meaning of Section
422 of the Internal  Revenue Code of 1986,  nonqualified stock options  ("NSOs")
and stock appreciation  rights ("SARs").   The 1994 Executive  Plan has  405,000
shares of the Corporation's Common Stock reserved for issuance.

     Options for 61,250  shares were granted  in 2002 and  at December 31,  2002
there were outstanding under this  Plan options for the  purchase of a total  of
162,745 shares.  There are 118,595 shares available for future grants under  the
1994 Executive Plan.  The 1994 Executive Plan will expire December 31, 2003.

OPTIONS OF NAMED EXECUTIVES

     Options to purchase shares of the  Corporation's Common Stock were  granted
to the named executive officers as reflected in the table below. Pursuant to the
terms of the 1994 Executive Plan, such options will become exercisable in  equal
thirds on  each of  the first  three anniversaries  of the  date of  grant.  Mr.
Conerton was granted options, as an outside director, after the effectiveness of
his resignation as an  officer; that grant  is not included  in this table.  See
"Compensation of Directors".

employment agreement;  Mr.  Rusch's  in a  severance  agreement.  The  agreement
remains in effect until the earliest to occur of the officer's:  (i) death; (ii)
disability; (iii) retirement; (iv) termination of employment (whether  voluntary
or involuntary); or (v)  termination in connection with  a change in control  of
the Bank or the Corporation.

     The agreements provide that, in the event of termination of his  employment
in connection with  a change  in control  of the  Bank or  the Corporation,  the
officer would receive  a severance  payment in an  amount equal  to his  average
annual compensation (defined to include his then current base annual salary plus
the average  bonus,  if  any, received  by  him  in the  three  years  preceding
termination) multiplied by three, plus an amount equal to the dollar  equivalent
of all contributions by the Bank on behalf of and for the benefit of the officer
to any pension,  profit sharing or  employee stock benefit  plan, including  the
Corporation's ESOP,  during the  three  years prior  to  the termination.    Mr.
Bastian's agreement  provides for  payment within  15 days  of termination.  Mr.
Rusch's agreement requires payment  of one-third of the  severance payment in  a
lump sum within 30 days of termination with the remaining two-thirds to be  paid
in  monthly   installments  commencing   in  the   thirteenth  month   following
termination.  In addition to this  severance payment, the officer would also  be
entitled to continue receiving, for three years following termination,  medical,
life and disability insurance benefits and vested benefits otherwise payable  to
him under  any  Bank  plan  or agreement  relating  to  retirement  or  deferred
compensation benefits, if  any.  In  the event Mr.  Rusch finds other  full-time
employment, his  severance  payment  in the  second  and  third  year  following
termination would be  reduced by an  amount equal to  salary and other  benefits
received from his new  employer during the  period for which  he is entitled  to
receive payments under his Severance Payment Agreement; Mr. Bastian's  agreement
is not subject  to that  adjustment.   Mr. Rusch's  Severance Payment  Agreement
provides that, in the event the  officer is under the  age of 55 and  physically
and medically able to perform duties  with another employer comparable to  those
performed by him  with the Bank  at the time  of his termination,  he must  take
reasonable steps to obtain  such employment within 50  miles of the Bank's  main
office.

     The agreements define a  change in control to  include: (i) acquisition  of
beneficial ownership  of securities  of the  Bank  or of  the Corporation  in  a
transaction subject to the notice provisions  of the Change in Bank Control  Act
of 1978 or approval  under the Bank  Holding Company Act  of 1956; (ii)  someone
other than  the  Corporation becoming  owner  of more  than  25% of  the  voting
securities of the Bank; (iii) the persons constituting the Board of Directors of
the Bank or the Corporation at any particular time ceasing, during any  two-year
period thereafter, to constitute at least  a majority thereof; (iv) a person  or
group of  persons  or entity  succeeding  to all  or  substantially all  of  the
business and/or assets of the Bank or the Corporation as a result of a purchase,
merger,  consolidation  or  similar  transaction;  or  (v)  the  filing  by  the
Corporation of a  report or  proxy statement  with the  Securities and  Exchange
Commission disclosing that  a change in  control of the  Corporation has or  may
have occurred pursuant  to any  contract or transaction.   A  termination of  an
officer is deemed to have  occurred in connection with  a change in control  if,
following an  event  defined  as  a change  in  control,  either  the  officer's
employment is  terminated by  the Bank  or  a successor  other than  for  death,
disability, retirement  or  certain wrongful  conduct  by the  officer,  or  the
officer terminates his employment on 90 days prior written notice following such
change in  control and  the  occurrence of  specified  events, including:    (i)
demotion in his position  or reduction in his  duties or responsibilities;  (ii)
reduction in compensation;  (iii) transfer  to a  remote location;  (iv) a  good
faith determination by the officer that he is unable, and it would not be in the
best interests  of the  Bank for  him,  to carry  out the  authorities,  powers,
functions, responsibilities or duties attached to  his position; or (v)  failure
on the part of the Bank  to obtain a commitment from  a successor to assume  the
Bank's duties and obligations under the agreements.  If an officer is terminated
within six months prior  to a change  in control for  reasons other than  death,
disability or cause, such termination will  be treated as being in  anticipation
of the  change in  control and  the  officer will  be  entitled to  receive  the
benefits he  would have  received  had the  termination  occurred after  and  in
connection with a change in control.

     Mr. Bastian's  employment  agreement provides  that  he shall  receive  the
severance amounts described  above, regardless  of whether  or not  a change  in
control has occurred, if he is terminated by the Corporation or the Bank without
cause or if he  terminates his employment for  cause.  The employment  agreement
further provides a  base salary  of $160,000 (subject  to annual  change by  the
board), specified benefits and  a term of three  years, commencing on  August 1,
2002, subject to annual extensions.

CONERTON RETIREMENT AGREEMENT

     Dennis  Conerton   retired,  and   resigned  from   employment,   effective
January 31, 2002.   In  connection therewith,  the Corporation  entered into  an
agreement with Mr.  Conerton relating to  the continuance  of certain  benefits.
Although the resignation was effective January 31, 2002, Mr. Conerton  continued
to draw salary, and  receive health insurance  benefits, through July 31,  2002.
His use of a company car extended through January 31, 2003.  In accordance  with
the relevant stock option plan, any  unexercised employee stock options held  by
Mr. Conerton expired on April 30, 2002.

     Mr. Conerton remains  a director  through the  annual meeting.   After  the
effectiveness of  his  resignation,  he  received  compensation  as  an  outside
director.  That  compensation included grants  of options  under the  directors'
stock option plan.

            SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

     Under the Securities Exchange Act of 1934, as amended (the "1934 Act"), the
Corporation's directors, executive officers and any person holding more than 10%
of the Corporation's Common Stock are required to report their initial ownership
of the Corporation's Common Stock and  any subsequent changes in that  ownership
to the Securities and Exchange Commission.  Specific due dates for these reports
have been established and the Corporation is required to disclose in this  Proxy
Statement any failure to file  such reports by these  dates during 2002.   Based
solely on a review of  copies of such reports  furnished to the Corporation,  or
written representations that no reports were required, the Corporation  believes
that during  2002  all  filing requirements  applicable  to  its  directors  and
executive officers were satisfied.

                CERTAIN TRANSACTIONS WITH MANAGEMENT AND OTHERS

     The Bank occasionally extends home mortgage loans, home improvement  loans,
home equity  loans,  consumer  loans and  commercial  loans  to  its  directors,
officers and employees, and affiliates of the foregoing.  Such loans are made in
the ordinary course of business and do not, in the opinion of management of  the
Bank, involve  more than  the normal  risk of  collectability or  present  other
unfavorable features, and are  made on substantially  the same terms,  including
interest rate and  collateral, as those  prevailing at the  time for  comparable
transactions with other persons.  Where the  borrower is also a director of  the
Bank, it is the policy of the Bank that he must leave the meeting of the  Bank's
Board  of  Directors  while  his  loan  is  being  considered  and  he   neither
participates in that consideration nor votes  on approval of the loan.   Messrs.
Hendricks, Puri and Bryden or their affiliates, each had one or more loans  with
the Bank with an aggregate outstanding balance at December 31, 2002 in excess of
$60,000.  As of that date,  those loans aggregated $9,691,067 which  represented
approximately 31.35% of the  capital of the  Bank at December  31, 2002.   Those
loans were all made in accordance with the policy described above.

                              OTHER INFORMATION

INDEPENDENT AUDITORS

     On  August 27, 2002, the  Audit and  Compliance  Committee of  the Board of
Directors of the  Corporation  approved  a  change  in  auditors. The  Board  of
Directors ratified the  Audit Committee's engagement of McGladrey &  Pullen, LLP
to serve as the Corporation's independent public accountants and replacement  of
Wipfli Ullrich Bertelson LLP (Wipfli") as the  Corporation's  independent public
accountants, effective August 28, 2002.

     Wipfli  performed audits  of the consolidated  financial statements for the
two  years ended  December 31, 2001 and 2000. Their reports  did not  contain an
adverse opinion or a disclaimer of opinion and were not qualified or modified as
to uncertainty, audit scope, or accounting principles.

     During the two years  ended December  31, 2001, and  from December 31, 2001
through  the   effective  date  of   the  Wipfli  termination,  there  were   no
disagreements between  the Corporation  and Wipfli on  any matter of  accounting
principles  or practice, financial  statement  disclosure, or  auditing scope or
procedure, which disagreements would have caused Wipfli to make reference to the
subject matter of such disagreements in connection with this report.

     During  the two  years ended December  31, 2001, and from December 31, 2001
until the effective date  of the  dismissal of Wipfli, Wipfli did not advise the
Corporation of any of the following matters:

1.   That the  internal  controls  necessary  for  the  Corporation  to  develop
reliable financial statements did not exist;

2.   That information had  come to  Wipfli's attention that  had lead  it to  no
longer be able  to rely  on management's representations,  or that  had made  it
unwilling to be associated with the financial statements prepared by management;

3.   That there was a need to expand significantly the scope of the audit of the
Corporation, or that information had come to Wipfli's attention that if  further
investigated: (i) may materially impact the fairness or reliability of either  a
previously-issued audit  report  or  underlying  financial  statements,  or  the
financial statements  issued  or  to  be  issued  covering  the  fiscal  periods
subsequent to the  date of the  most recent financial  statements covered by  an
audit report  (including  information that  may  prevent it  from  rendering  an
unqualified audit report on those financial statements) or (ii) may cause it  to
be unwilling to rely  on management's representation or  be associated with  the
Corporation's financial statements and  that, due to  its dismissal, Wipfli  did
not so expand the scope of its audit or conduct such further investigation;

4.   That information  had come  to Wipfli's  attention  that it  had  concluded
materially impacted the  fairness or reliability  of either:  (i) a  previously-
issued audit report or the underlying financial statements or (ii) the financial
statements issued or to be issued  covering the fiscal period subsequent to  the
date of  the  most  recent  financial statements  covered  by  an  audit  report
(including information that, unless  resolved to the accountant's  satisfaction,
would prevent it from rendering an  unqualified audit report on those  financial
statements), or that, due to its dismissal, there were no such unresolved issues
as of the date of its dismissal.

     Wipfli furnished a letter to the SEC stating that it agrees with the  above
statements.

     During the two years  ended December 31, 2001,  and from December 31,  2001
through engagement of McGladrey & Pullen,  LLP as the Corporation's  independent
accountant, neither  the Corporation  nor anyone  on  its behalf  had  consulted
McGladrey &  Pullen, LLP  with  respect to  any  accounting or  auditing  issues
involving the  Corporation. In  particular, there  was  no discussion  with  the
Corporation regarding the  application of accounting  principles to a  specified
transaction, the type of audit opinion  that might be rendered on the  financial
statements, or any related item

              RATIFICATION OF APPOINTMENT OF INDEPENDENT AUDITORS

Dear Fellow Shareholder:

I cordially invite you attend the Blackhawk Bancorp Annual Meeting at 10:00 A.M.
on May 21, 2003 at the Beloit Country Club.

Accompanying this letter is the formal Notice of Annual Meeting of Shareholders,
Proxy Statement and 2002 Annual Report.  The Proxy Statement sets forth the
business to be acted upon including the election of directors.

Because of business and personal commitments Dennis Conerton and Sunil Puri have
asked that their names not be resubmitted as nominees to the Board of Directors
for three year terms beginning with this year's annual meeting.  They have both
been loyal, engaged and involved directors.  While retaining their friendship,
we will miss their counsel.

Your board is pleased to nominate in their place Mr. Stephen Carter and Mr.
Stephen Thomas.  Subject to your approval, they will join Mr. Hendricks and Mr.
Merchant as directors elected to three year terms.

Mr. Carter is Executive Vice President and Chief Financial Officer of Woodward
Governor.  He will add to our board valuable financial expertise and experience
in the governance of publicly held companies.  Mr. Thomas is a native of Boone
County with deep roots in the community and a number of successful businesses
including the Poplar Grove Airport.  He will be very helpful in supporting our
growing presence in Boone County, the second fastest growing county in Illinois.

That Boone County presence will be significantly strengthened with our
acquisition of DunC Corp. and its subsidiary, First Bank, bc.  We expect the
merger to take place sometime in late summer after receipt of approvals from
regulators and DunC shareholders.  We will spend some time at the annual meeting
sharing this exciting development with you.  In case you missed the
announcement, a copy of the press release is attached.

I look forward to seeing you at the annual meeting.

Sincerely,

/s/R. Richard Bastian, III

March 18, 2003

                BLACKHAWK STATE BANK AND FIRST BANK, BC TO MERGE
                ------------------------------------------------

                  ACTION UNDERSCORES BLACKHAWK'S COMMITMENT TO
                           THE GREATER ROCKFORD AREA

  BELOIT, WISCONSIN, MARCH 18, 2003---  Blackhawk Bancorp, Inc. (OTC: BKHB)  and
  DunC Corp.  jointly announced today  they have signed  a definitive  agreement
  for Blackhawk Bancorp  to acquire DunC Corp.  and its subsidiary, First  Bank,
  bc,  for $7.2  million, or  $1,518  per share.    The agreement  provides  for
  certain adjustments in price based on the performance of DunC.

  The acquisition is expected to be  completed in the third quarter of 2003  and
  is  subject to  DunC shareholder  and regulatory  approval and  other  closing
  conditions.

  Blackhawk Bancorp,  Inc., which  on February  21, 2003  reported 2002  diluted
  earnings per share of $0.50, a  39% increase over 2001, is the parent  company
  of Blackhawk  State Bank,  which operates  nine offices  in Beloit,  Rockford,
  Roscoe, Belvidere, Rochelle and Oregon.  It employs 150 people and has  assets
  of $350 million.

  First  Bank,  bc,  with assets  of  approximately  $75  million  and  over  40
  employees, is  headquartered in Capron,  Illinois.  It  has four full  service
  locations  in Illinois  including Capron,  Belvidere, Rockford  and  Machesney
  Park.   First Bank,  bc offers  a full range  of retail,  commercial and  real
  estate banking services.

  "This affiliation  is a natural  fit to our  existing branch  network and  our
  strategies  for growth,"  said R.  Richard Bastian  III, President  and  Chief
  Executive Officer  of Blackhawk Bancorp, Inc.  "It underscores our  commitment
  to be the premier community bank in the Greater Rockford Area."

  "After  completion of  this  merger, Blackhawk  will  rank second  in  deposit
  balances  in fast  growing Boone  County.   It also  picks up  a  full-service
  facility  in the  rapidly developing  Rte 173  and Forest  Hills Rd.  area  of
  Machesney Park, IL," he said.

  "We believe that strong capital, sound asset quality and exceptional  customer
  service provided by outstanding employees are the keys to our success now  and
  into the  future. We expect that  this merger will  help Blackhawk State  Bank
  create an  even stronger financial  services company with  a broader array  of
  services and locations," continued Bastian.

  "The   merger  will   provide  greater   convenience  for   clients  of   both
  organizations  offering them  12  banking  locations in  the  stateline  area,
  including three in the Rockford area."

  Donald  H. Pratt,  Chairman and  Chief Executive  Officer of  DunC, Corp.  and
  First  Bank, bc  is  also pleased  with  what the  merger  will bring  to  his
  customers.

  "Blackhawk is  an ideal partner for  First Bank. Our customers can be  assured
  they will  continue to receive  the personal attention  that only a  community
  bank can provide.  In addition, they will have the added benefit of access  to
  a broader  line of  products and  services, including  internet banking,  cash
  management and trust services.

  "We chose  Blackhawk because  of their focus  on community  banking and  their
  commitment to  maintaining close customer  relationships," said Pratt.  "We're
  very comfortable  with their leadership as  several members of our  management
  team, including myself, have worked with Rick Bastian in the past."

  Bastian and  Pratt were both  executives of First  Community Bancorp prior  to
  its acquisition by Bank One in  1993.  At the time of its acquisition by  Bank
  One,  First Community  was the  second largest  financial institution  in  the
  Rockford area.

  Transition  teams with  employees  from both  banks  will be  working  in  the
  upcoming months to  make the merger as seamless  as possible for business  and
  consumer clients of both banks, according to Bastian.

  In  connection  with  this transaction,  Alex  Sheshunoff  &  Co.,  Investment
  Banking  acted as  financial  advisor to  DunC  Corp.   Hinshaw  &  Culbertson
  represented DunC Corp. as legal counsel.  Howe Barnes Investments, Inc.  acted
  as  Blackhawk Bancorp,  Inc.' s  financial  advisor and  Quarles &  Brady  LLP
  served as its legal counsel.
