 2 TIDEWATER TIDEWATER 601 Poydras Street, Suite 1900 New Orleans, LA 70130 FORWARD-LOOKING STATEMENTS In accordance with the safe harbor provisions of the Private Securities Litigation Reform Act of 1995, the Company notes that certain statements set forth in this presentation provide other than historical information and are forward looking. The actual achievement of any forecasted results, or the unfolding of future economic or business developments in a way anticipated or projected by the Company, involve numerous risks and uncertainties that may cause the Company’s actual performance to be materially different from that stated or implied in the forward-looking statement. Among those risks and uncertainties, many of which are beyond the control of the Company, include, without limitation, fluctuations in worldwide energy demand and oil and gas prices; fleet additions by competitors and industry overcapacity; changes in capital spending by customers in the energy industry for offshore exploration, development and production; changing customer demands for different vessel specifications, which may make some of our older vessels technologically obsolete for certain customer projects or in certain markets; instability of global financial markets and difficulty accessing credit or capital; acts of terrorism and piracy; significant weather conditions; unsettled political conditions, war, civil unrest and governmental actions, especially in higher risk countries of operations; foreign currency fluctuations; and enforcement of laws related to the environment, labor and foreign corrupt practices. Participants should consider all of these risk factors as well as other information contained in the Company’s form 10-K’s and 10-Q’s.
