              Manufacturing Co.

     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-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 officer and I have disclosed,
              based on our most recent evaluation, 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 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 officer 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.
