 CERTIFICATION PURSUANT TO RULE 13a-14(a)/15d-14(a) OF THE SECURITIES EXCHANGE
  ACT OF 1934, AS ADOPTED PURSUANT TO SECTION 302 OF THE SARBANES-OXLEY ACT OF

      I, Michael T. Vea, certify that:

            1. I have reviewed this annual report on Form 10-K of Integra Bank
      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 company as of, and for, the periods presented in this report;

            4. The company'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)) and internal
      control over financial reporting (as defined in Exchange Act Rules
      13a-15(f) and 15d-15(f)) for the company 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 company, 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 company'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 company's internal
      control over financial reporting that occurred during the company'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 company's internal control over financial
      reporting; and

            5. The company's other certifying officer and I have disclosed,
      based on our most recent evaluation of internal control over financial
      reporting, to the company's auditors and the audit committee of the
      company'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 company'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.
