  1.
    
    I have reviewed this quarterly report on
Form 10-Q of Anchor BanCorp Wisconsin Inc.;2.
    
    Based on my knowledge, this report does
not contain any untrue statement of a material
fact or omit to state a material fact
necessary to make the statements made, in
light of the circumstances under which such
statements were made, not misleading with respect
to the period covered by this report;3.
    
    Based on my knowledge, the financial
statements, and other financial information included
in this report, fairly present in all material
respects the financial condition, results of
operations and cash flows of the registrant as
of, and for, the periods presented in this
report;4.
    
    The registrants other certifying officers and
I are responsible for establishing and maintaining
disclosure controls and procedures (as defined in
Exchange Act Rules 13a-15(e) and 15d-15(e)) and
internal control over financial reporting (as
defined in Exchange Act Rules 13a-15(f) and
15d-15(f)) for the registrant and have:
 (a)
    
    Designed such disclosure controls and
procedures, or caused such disclosure controls
and procedures to be designed under our
supervision, to ensure that material information
relating to the registrant, including its
consolidated subsidiaries, is made known to
us by others within those entities,
particularly during the period in which this
report is being prepared;(b)
    
    Designed such internal control over
financial reporting, or caused such internal
control over financial reporting to be
designed under our supervision, to provide
reasonable assurance regarding the reliability of
financial reporting and the preparation of
financial statements for external purposes in
accordance with generally accepted accounting principles;(c)
    
    Evaluated the effectiveness of the
registrants disclosure controls and procedures and
presented in this report our conclusions
about the effectiveness of the disclosure
controls and procedures, as of the end
of the period covered by this report
based on such evaluation; and(d)
    
    Disclosed in this report any change in
the registrants internal control over financial
reporting that occurred during the registrants
most recent fiscal quarter (the registrants
fourth fiscal quarter in the case of an
annual report) that has materially affected,
or is reasonably likely to materially affect,
the registrants internal control over financial
reporting; and
 5.
    
    The registrants other certifying officers and
I have disclosed, based on our most recent
evaluation of internal control over financial
reporting, to the registrants auditors and the
audit committee of registrants board of directors
(or persons performing the equivalent functions):
 (a)
    
    All significant deficiencies and material
weaknesses in the design or operation of
internal control over financial reporting which
are reasonably likely to adversely affect the
registrants ability to record, process, summarize
and report financial information; and
 (b)
    
    Any fraud, whether or not material,
that involves management or other employees
who have a significant role in the
registrants internal control over financial
reporting.
