CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

We desire to take advantage of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995, or the PSLRA, and are including this cautionary statement in connection therewith. The PSLRA provides safe harbor protections for forward-looking statements in order to encourage companies to provide prospective information about their business.

Forward-looking statements include statements concerning plans, objectives, goals, strategies, future events or performance, and underlying assumptions and other statements, which are other than statements of historical or present facts or conditions.

This Annual Report and any other written or oral statements made by us or on our behalf may include forward-looking statements which reflect our current views with respect to future events and financial performance. The words "believe," "anticipate," "intend," "estimate," "forecast," "project," "plan," "potential," "may," "should," "expect" and similar expressions identify forward-looking statements.

The forward-looking statements in this document 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 we believe 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, we cannot assure you that we will achieve or accomplish these expectations, beliefs or projections.

In addition to these important factors and matters discussed elsewhere in this Annual Report, and in the documents incorporated by reference in this Annual Report, important factors that, in our view, could cause actual results to differ materially from those discussed in the forward-looking statements include:

• factors related to the offshore drilling market, including changes in oil and gas prices and the state of the global economy on market outlook for our various geographical operating sectors and classes of rigs;

• supply and demand for drilling units and competitive pressure on utilization rates and dayrates;

• customer contracts, including contract backlog, contract commencements, contract terminations, contract option exercises, contract revenues, contract awards and rig mobilizations;

• the repudiation, nullification, modification or renegotiation of contracts;

• delays in payments by, or disputes with our customers under our drilling contracts;

• fluctuations in the market value of our drilling units and the amount of debt we can incur under certain covenants in our debt financing agreements;

• the liquidity and adequacy of cash flow for our obligations;

• our ability to successfully employ our drilling units ;

• our ability to procure or have access to financing;

• our expected debt levels;

• our ability to comply with certain covenants in our debt financing agreements;

• credit risks of our key customers;

• political and other uncertainties, including political unrest, risks of terrorist acts, war and civil disturbances, public health threats, piracy, corruption, significant governmental influence over many aspects of local economies, or the seizure, nationalization or expropriation of property or equipment;

• the concentration of our revenues in certain jurisdictions;

• limitations on insurance coverage, such as war risk coverage, in certain areas;

• our inability to repatriate income or capital;

• the operation and maintenance of our drilling units, including complications associated with repairing and replacing equipment in remote locations and maintenance costs incurred while idle;

• newbuildings, upgrades, shipyard and other capital projects, including the completion, delivery and commencement of operation dates;

• import-export quotas;

• wage and price controls and the imposition of trade barriers;

• recruitment and retention of personnel;

• regulatory or financial requirements to comply with foreign bureaucratic actions, including potential limitations on drilling activity, changing taxation policies and other forms of government regulation and economic conditions that are beyond our control;

• the level of expected capital expenditures, our expected financing of such capital expenditures and the timing and cost of completion of capital projects;

• fluctuations in interest rates or exchange rates and currency devaluations relating to foreign or U.S. monetary policy;

• tax matters, changes in tax laws, treaties and regulations, tax assessments and liabilities for tax issues, including those associated with our activities in Bermuda, Norway, the United Kingdom and Russia;

• legal and regulatory matters, including the results and effects of legal proceedings, and the outcome and effects of internal and governmental investigations;

• hazards inherent in the drilling industry and marine operations causing personal injury or loss of life, severe damage to or destruction of property and equipment, pollution or environmental damage, claims by third parties or customers and the suspension of operations;

• customs and environmental matters; and

• other important factors described from time to time in the reports filed or furnished by us with the Securities and Exchange Commission, or the Commission, and the New York Stock Exchange, or the NYSE.

We caution readers of this Annual Report not to place undue reliance on these forward-looking statements, which speak only as of their dates. We undertake no obligation to update any forward-looking statement or statements to reflect events or circumstances after the date on which such statement is made or to reflect the occurrence of unanticipated events. New factors emerge from time to time, and it is not possible for us to predict all of these factors. Further, we cannot assess the impact of each such factor on our business or the extent to which any factor, or combination of factors, may cause actual results to be materially different from those contained in any forward-looking statement.
