 **Certification
      of Chief Executive Officer Pursuant to Section 302(a) of the Sarbanes-Oxley
      Act
      of 2002**
 
 I,
      Thomas K. Grove, certify that:
 
 1.
      I have reviewed this report on Form 10-Q of
      Oregon Pacific Bancorp;
 
 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)) for the
      registrant and we have:
 
 a)
      Designed such disclosure controls and
      procedures, or caused such disclosure controls and procedures to be designated
      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 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 the registrant's board of directors (or persons performing the equivalent
      function):
 
 a)
      All significant deficiencies and material
      weaknesses in the design or operation of internal controls 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 controls over financial reporting.
