with significant customers; the outcome of discussions with customers concerning
potential antitrust claims; the impact of negative publicity; environmental
challenges and natural conditions facing the Company's aquaculture business; the
impact of laws and regulations; operating hazards, including marine disasters,
spills or environmental damage; the conditions and factors that may influence
the decision to issue future dividends; and the market for long-term debt. Many
of these factors are beyond the Company's ability to control or predict. Given
these factors, you should not place undue reliance on the forward-looking
statements. Should one or more of these risks or uncertainties occur, or should
management's assumptions or estimates prove incorrect, actual results and events
