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

I, Peter Katevatis, certify that:

      (1)   I have reviewed this quarterly report on Form 10-QSB of Mediscience
            Technology Corp.;

      (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 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)    evaluated the effectiveness of the registrant's disclosure
                  controls and procedures and presented in this quarterly 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 the report any change in the registrant's
                  internal control over financial reporting that has occurred
                  during the registrant's most recent fiscal quarter (the
                  registrant's fourth fiscal quarter in the case of the 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 functions):

            a)    all significant deficiencies 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.
