SECTION 5 - CORPORATE GOVERNANCE AND MANAGEMENT

    ITEM 5.03     AMENDMENT TO ARTICLES OF INCORPORATION OR BYLAWS; CHANGE IN
                  FISCAL YEAR.

                The Board of Directors of Haemonetics Corporation ("Haemonetics"
                or the "Company") amended the Company's by-laws effective March
                31, 2005. The amendments primarily are designed to conform the
                by-laws to the provisions of the Massachusetts Business
                Corporation Act (the "MBCA"), which became effective on July 1,
                2004. Previously, the Company was subject to the provisions of
                the Massachusetts Business Corporation Law (the "MBCL"). This
                report contains a summary of the revisions made to the by-laws.
                The descriptions of provisions of the by-laws are qualified in
                their entirety by reference to the by-laws, a copy of which is
                filed as an Exhibit to this Current Report on Form 8-K.

                        Many of the amendments were made to conform the language
                of the by-laws to that used in the MBCA. By-law provisions
                frequently replicate statutory provisions; accordingly, in many
                cases, the by-laws were modified to reflect language differences
                between the MBCA and the MBCL. Some changes reflect logistical
                matters, such as the use electronic transmission.

                        Changes include the following:

                        The amended by-laws have deleted the term
                "stockholder(s)" and it has been replaced by the term
                "shareholder(s)". Under the MBCL, Massachusetts corporations
                were required to have a clerk. The MBCA requires Massachusetts
                corporations to have a secretary. The amendments to the by-laws
                replace references to the clerk with references to the
                secretary.

                        The MBCL required that an annual meeting be held within
                six (6) months of the fiscal year end, and the prior by-laws
                reflected that requirement. Because a comparable provision is
                not contained in the MBCA, the applicable language has been
                removed from the by-laws.

                        The MBCA revised the requirements regarding a
                corporation's obligation to notify its shareholders of an
                upcoming annual or special meeting. The MBCL required that
                notice be delivered to shareholders at least seven (7) days
                prior to the date of the meeting. The MBCA requires that notice
                be given no fewer than seven (7) days nor

                                        2


                more than sixty (60) days prior to the date of the meeting. The
                amended by-laws conform with the timing provisions of the MBCA.

                        The by-laws also have been amended to explicitly provide
                that, in addition to traditional delivery methods, notice of an
                annual or special shareholder meeting may be delivered to a
                shareholder by electronic transmission in a manner specified to
                the Company by the shareholder.

                        The MBCA provides that, absent a contrary provision in
                the Articles of Organization, the purposes of a shareholder
                meeting must be included in the notice to shareholder of the
                meeting. The amended by-laws provide that, as a condition to
                constituting valid business at an annual meeting, a proposal
                must be made in accordance with the by-laws. Notwithstanding
                that requirement, the by-laws do not affect any rights of
                shareholders to request inclusion of proposals in the Company's
                proxy statement pursuant to Rule 14a-8 under the Securities
                Exchange Act.

                        The MBCA introduces the concept of "voting groups". A
                voting group consists of all shares of one or more classes or
                series of capital stock that, under the Articles of Organization
                or the MBCA, are entitled to vote and to be counted together
                collectively on a matter at a meeting of shareholders. The
                amended by-laws incorporate the concept of voting groups in the
                provisions dealing with establishing quorums and determining
                whether matters presented to the shareholders have been
                approved. With respect to each voting group, when a quorum is
                present, a director is elected by a plurality of votes properly
                cast for election of that director, while all other matters are
                considered approved when votes properly cast in favor of the
                matter exceed the votes properly cast in opposition to the
                matter, in each case, except when a different vote is required
                by law, the Articles of Organization, or the by-laws.
