I, Kenneth R. Shannon, certify that:

1.       I have reviewed this annual report on Form 40-F (the "Report") of
         Corriente Resources Inc. (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 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 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.  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; and

              c.  Disclosed in this Report any change in the Registrant's
                  internal control over financial reporting that occurred
                  during the period covered by this 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 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
         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 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 issuer's
                  internal control over financial reporting.
