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

I, Birge Bargmann, 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 small business issuer 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)) for the small business issuer and I 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 small business issuer, 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)    evaluated the effectiveness of the small business issuer'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

            c)    disclosed in this report any change in the small business
                  issuer's internal control over financial reporting that
                  occurred during the small business issuer most recent fiscal
                  quarter that has materially affected, or is reasonably likely
                  to affect, the small business issuer'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 small business issuer's
            auditors and the audit committee of small business issuer'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
                  small business issuer 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 small
                  business issuer's internal control over financial reporting.
