**Certification
      of Chief Executive Officer Pursuant to Section 302(a) of the Sarbanes-Oxley
      Act
      of 2002**





I,
      James P. Clark, 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.
