   I,
        Mary
        Jo David, certify that:
  1.  I
        have
        reviewed this quarterly report on Form 10-Q of LSB Financial Corp. (the
“Registrant”);
  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 consolidated financial statements, and other financial
        information included in this report, fairly present in all material respects
        the
        consolidated 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 officer 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, 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)  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 changes in the Registrant’s internal control over financial
        reporting that occurred during the Registrant’s most recent fiscal quarter 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 officer 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.
