The statements in this release relating to matters that are not historical facts
are  forward-looking   statements  that  represent   management's   beliefs  and
assumptions based on currently available information. Forward-looking statements
can be identified by the use of words such as "will," "anticipates,"  "expects,"
or comparable  terminology or by discussions of strategy or trends.  Although we

reasonable,  it cannot give any assurances that these expectations will prove to
be correct.  Such  statements by their nature  involve risks and  uncertainties,

financial  market  conditions,  changes  in  foreign  currency  exchange  rates,
operating interruptions  (including,  but not limited to, labor disputes, leaks,
fires, explosions,  unscheduled downtime,  transportation interruptions, war and
terrorist  activities),  and  other  risks  and  uncertainties  detailed  in our
Securities and Exchange  Commission  filings.  Should one or more of these risks
materialize (or the  consequences of such a development  worsen),  or should the
underlying  assumptions prove incorrect,  actual results could differ materially
from those  forecasted  or expected.  We disclaim any intention or obligation to
update  publicly  or  revise  such  statements,  whether  as  a  result  of  new
information, future events or otherwise.
