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;

uncertainty of global financial market conditions and difficulty accessing credit or capital; acts of terrorism and

piracy; significant weather conditions; unsettled political conditions, war, civil unrest and governmental actions, such

as expropriation or enforcement of customs or other laws that are not well-developed or consistently enforced,

especially in higher political risk countries where we operate; foreign currency fluctuations; labor changes proposed

by international conventions; increased regulatory burdens and oversight; and enforcement of laws related to the

environment, labor and foreign corrupt practices. Readers should consider all of these risks factors, as well as other

information contained in the Company’s form 10-K’s and 10-Q’s.
