                           Certification of President
            Pursuant to Section 302 of the Sarbanes-Oxley Act of 2002
            ---------------------------------------------------------

         I, Lyn G. Rupich, certify that:

1.    I have reviewed this annual report on Form 10-K of AJS Bancorp, Inc.;

2.    Based on my  knowledge,  this  annual  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 annual report;

3.    Based on my  knowledge,  the  financial  statements,  and other  financial
      information included in this annual 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  annual
      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)) for the registrant
      and have:

      a)    designed  such  disclosure  controls and  procedures  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 annual
            report is being prepared;

      b)    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

      c)    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;

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 the 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.
