                   CERTIFICATION PURSUANT TO RULE 13A-14(A) OF
                             CHIEF EXECUTIVE OFFICER


I, Douglas Good, certify that:

1.   I have  reviewed  this annual  report on Form 20-F of  Rochester  Resources
     Ltd.;

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 company as of, and for, the periods presented in this report;

4.   As the sole  certifying  officer,  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 company 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 company,  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  company'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 company's  internal
                  control over  financial  reporting  that  occurred  during the
                  period  covered  by the  annual  report  that  has  materially
                  affected,  or is reasonably likely to materially  affect,  the
                  company's internal control over financial reporting; and

5.   As the sole certifying  officer, I have disclosed,  based on my most recent
     evaluation of internal control over financial  reporting,  to the company's
     auditors and the audit  committee of the  company'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
                  company'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
                  company's internal control over financial reporting.
