                               CERTIFICATIONS

I, Mary Lynn D. Lenz, certify that:

1.    I have reviewed this quarterly report on Form 10-Q of Slade's Ferry
      Bancorp;

2.    Based on my knowledge, this quarterly 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 quarterly report;

3.    Based on my knowledge, the financial statements, and other financial
      information included in this quarterly 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 quarterly 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)] 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 quarterly 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 quarterly report based on such evaluation; and

      c.    Disclosed in this quarterly 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
      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.
