Forward-Looking Statements

The information in this press release may contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements include, but are not limited to, statements regarding: (1) the delivery and operation of assets of Star Bulk; (2) Star Bulk's future operating or financial results; (3) future, pending or recent acquisitions, business strategy, areas of possible expansion, and expected capital spending or operating expenses; (4) drybulk market trends, including charter rates and factors affecting vessel supply and demand; (5) the planned exchange offer; and (6) other statements identified by words such as "anticipate," "believe," "plan," "estimate," "expect," "intend," "should," "may," or words of similar meaning.

Such forward-looking statements are based upon various assumptions, many of which are based, in turn, upon further assumptions, including without limitation, Star Bulk's examination of historical operating trends, data contained in their records and other data available from third parties. Although Star Bulk 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 its control, Star Bulk cannot assure you that Star Bulk will achieve or accomplish these expectations, beliefs or projections. Important factors that could cause actual results to differ materially from those discussed in the forward-looking statements include the failure of a seller to deliver one or more vessels, 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 Star Bulk'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. Additional factors that could cause Star Bulk's results to differ materially from those described in the forward-looking statements can be found in Star Bulk's Annual Report on Form 20-F for the year ended December 31, 2008, Registration Statement on Form F-3 filed in September 2008 as amended, in Registration Statement on Form F-3 filed in January 2009 as amended, and reports on Form 6-K filed with the Securities and Exchange Commission (the "SEC") and available at the SEC's Internet site (http://www.sec.gov). The information set forth herein speaks only as of the date hereof, and Star Bulk disclaims any intention or obligation to update any forward-looking statements as a result of developments occurring after the date of this communication.
