                                                           ------------

                                CERTIFICATION
                                -------------

I, Brad Nutter, President and Chief Executive Officer of Haemonetics
Corporation, certify that:

      1.    I have reviewed this quarterly report on Form 10-Q of
            Haemonetics Corporation;

      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 registrant as
            of, and for, the periods presented in 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)) 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)    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

            c)    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 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.
