                    CERTIFICATION OF CHIEF FINANCIAL OFFICER
            PURSUANT TO SECTION 302 OF THE SARBANES-OXLEY ACT OF 2002

         I, Walter J. Thomsen, certify that:

         1.       I have reviewed this report on Form 10-QSB of Proteo, Inc.;

         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.       I am 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 registrant and have:

                  a)       designed such disclosure controls and procedures, or
                           caused such disclosure controls and procedures to be
                           designed under my supervision, to ensure that
                           material information relating to the registrant,
                           including its consolidated subsidiaries, is made
                           known to me 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 my
                           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 registrant's
                           disclosure controls and procedures and presented in
                           this report my 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
                           registrant's internal control over financial
                           reporting that occurred during the registrant's most
                           recent fiscal quarter that has materially affected,
                           or is reasonably likely to affect, the registrant's
                           internal control over financial reporting; and;

         5.       I have disclosed, based on my 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 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;
                           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
