    I have reviewed this quarterly report on Form 10-Q of First Financial Corporation;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 officer(s) 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 l5d-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 purpose 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; andd.
    
    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 officer(s) 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; andb.
    
    Any fraud, whether or not material, that involves management or other employees who
have a significant role in the registrants internal controls over financial reporting.
