                    Certification of Chief Executive Officer
           Pursuant to Section 302 of the Sarbanes-Oxley Act of 2002


I, George Strayton, certify that:

1.    I have reviewed this Quarterly Report on Form 10-Q/A of
      Provident New York Bancorp;

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;

4.    The registrant's other certifying officer 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)) and internal control over financial
      reporting (as defined in Exchange Act Rules 13a-15(f) and
      15d-15(f)) 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)    Designed such internal control over financial reporting, or
            caused such internal control over financial reporting to be
            designed under our 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 registrant's disclosure
            controls and procedures and presented in this 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

      d)    Disclosed in this report any change in the registrant's
            internal control over financial reporting that occurred during
            the registrant's most recent fiscal quarter (the registrant's
            fourth fiscal quarter in the case of an 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 officer 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 and material weaknesses 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.
