I, Leonard F. Leganza, certify that:

1.            I have reviewed this quarterly report on Form 10-Q of The Eastern
              Company;

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 annual report;

4.            The registrant's other certifying officers and I are responsible
              for establishing and maintaining disclosure controls and
              procedures (as defined in Exchange Act Rules 13a-14 and 15d-14)
              for the registrant and we have:

      a)      designed such disclosure controls and procedures 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 as of a date within 90 days prior to the
              filing date of this quarterly report (the "Evaluation Date"); and

      c)      presented in this quarterly report our conclusions about the
              effectiveness of the disclosure controls and procedures based on
              our evaluation as of the Evaluation Date;

5.            The registrant's other certifying officers and I have disclosed,
              based on our most recent evaluation, to the registrant's auditors
              and the audit committee of registrant's board of directors (or
              persons performing the equivalent function):

      a)      all significant deficiencies in the design or operation of
              internal controls which could adversely affect the registrant's
              ability to record, process, summarize and report financial data
              and have identified for the registrant's auditors any material
              weaknesses in internal controls; and

      b)      any fraud, whether or not material, that involves management or
              other employees who have a significant role in the registrant's
              internal controls; and

6.            The registrant's other certifying officers and I have indicated in
              this quarterly report whether or not there were significant
              changes in internal controls or in other factors that could
              significantly affect internal controls subsequent to the date of
              our most recent evaluation, including any corrective actions with
              regard to significant deficiencies and material weaknesses.
