CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

Certain matters discussed herein may constitute forward-looking statements. The Private Securities Litigation Reform Act of 1995 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 facts.

The Company desires to take advantage of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995 and is including this cautionary statement in connection with this safe harbor legislation. This 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 and are not intended to give any assurance as to future results. When used in this document, the words “believe,” “expect,” “anticipate,” “estimate,” “intend,” “plan,” “target,” “project,” “likely,” “will,” “would,” “may,” “seek,” “continue,” “possible,” “might,” “forecast,” “potential,” “should,” “could” and similar expressions, terms, or phrases may identify forward-looking statements.

The forward-looking statements are based upon various assumptions, many of which are based, in turn, upon further assumptions, including without limitation, our 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. We undertake no obligation to update any forward-looking statement, whether as a result of new information, future events or otherwise.

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 fluctuations in charter rates and vessel values, changes in demand in the tanker market, as a result of changes in the petroleum production levels set by the Organization of the Petroleum Exporting Countries, or OPEC, and worldwide oil consumption and storage, changes in our operating expenses, including bunker prices, drydocking and insurance costs, the market for our vessels, availability of financing and refinancing, changes in governmental rules and regulations or actions taken by regulatory authorities, potential liability from pending or future litigation and potential costs due to environmental damage and vessel collisions, general domestic and international political conditions or events including “trade wars”, potential disruption of shipping routes due to accidents or political events, severe weather conditions, natural disasters, the length and severity of future epidemics and pandemics and their impact on the demand for seaborne transportation in the tanker sector, vessel breakdowns and instances of off-hire, failure on the part of a seller to complete a sale of a vessel to us and other important factors described from time to time in the reports filed by the Company with the Securities and Exchange Commission, or the SEC.
