            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  the  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

      (2)  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.
