 Why Raise Equity Now  We currently have a fleet growth newbuilding program for 4 vessels costing about $118mHave ordered 2 Ultramaxes 63,000 dwt and 2 Kamsarmaxes of 82,000 dwt at Chinese yardsFunds in hand are not sufficient to fulfill the program (due to the market deterioration over the last 2 years) and at the same time maintain a solid balance sheet as we have always doneTo finance our newbuilding program, we have the option to sell some vessels, possibly some of the newbuildings, or raise equityWe believe that in today’s market of extremely low vessel prices, shipping companies should buy vessels and not dispose of them (see slides below)Thus, for us raising equity is the preferred choiceA Shareholders’ Rights Offering offers the possibility for all current shareholders to participate in the offering at the same non-dilutive terms   4 

 Why Pursue A Shareholders Rights Offering  Main reasons we decided to pursue a Rights Offering Vs other equity raising optionsNo dilution to fully participating shareholders Alternative fundraising options (follow-ons, ATMs, convertibles, private placements, etc.) could all be potentially more dilutive for shareholdersExpenses of the offering are low relative to other capital raising options (no underwriting fees, lower legal costs)  5
