Forward-Looking Statements

Matters discussed in this release may constitute forward-looking
statements. Forward-looking statements reflect our current views with
respect to future events and financial performance and may include
statements concerning plans, objectives, goals, strategies, future events
or performance, and underlying assumptions and other statements, which are
other than statements of historical facts.

The forward-looking statements in this release are based upon various
assumptions, many of which are based, in turn, upon further assumptions,
including without limitation, management's examination of historical
operating trends, data contained in our records and other data available
from third parties. Although DryShips Inc. believes that these assumptions
were reasonable when made, because these assumptions are inherently
subject to significant uncertainties and contingencies which are
difficult or impossible to predict and are beyond our control, DryShips
Inc. cannot assure you that it will achieve or accomplish these
expectations, beliefs or projections.

Important factors that, in our view, could cause actual results to differ
materially from those discussed in the forward-looking statements include
the strength of world economies and currencies, general market conditions,
including changes in charterhire rates and vessel values, changes in
demand that may affect attitudes of time charterers to scheduled and
unscheduled drydocking, changes in DryShips Inc.'s operating expenses,
including bunker prices, dry-docking and insurance costs, or actions
taken by regulatory authorities, potential liability from pending or
future litigation, domestic and international political conditions,
potential disruption of shipping routes due to accidents and political
events or acts by terrorists.

Risks and uncertainties are further described in reports filed by DryShips
Inc. with the US Securities and Exchange Commission.
