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

I, Peter Katevatis,  Chief Executive  Officer of Mediscience  Technology  Corp.,
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 small  business  issuer  as of,  and for,  the  periods
            presented in this report;

      (4)   The small  business  issuer'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 small business issuer 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  small  business  issuer,  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 small  business  issuer'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 this  report  any  change in the small  business
                  issuer's  internal  control  over  financial   reporting  that
                  occurred during the small business issuer's most recent fiscal
                  quarter (the small business  issuer's fourth fiscal quarter in
                  the case of the annual report) that has  materially  affected,
                  or is  reasonably  likely  to  materially  affect,  the  small
                  business issuer's  internal control over financial  reporting;
                  and

      (5)   The small  business  issuer's other  certifying  officers and I have
            disclosed,  based on our most recent  evaluation of internal control
            over financial  reporting,  to the small business  issuer's auditors
            and the audit  committee  of the 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.
