shareholders.


"The expansion of the Board of Directors with an additional outside  independent
member,  as well as the  simplification  of the Board  structure  and removal of
anti-takeover provisions from the Company Charter, is in keeping with the spirit
of the  Sarbanes-Oxley  Act of 2002," stated John A.  O'Malley,  Chairman of the
Board of IRIS  International.  "Although  we have no  intention  of  selling  or
merging  the  Company  at this  time,  we  believe  the  decision  to remove the

actions  underscore  the Board's desire to ensure  greater  transparency  of the
Company's business practices among shareholders and the investment community."
