PIRAEUS, GREECE -- (MARKET WIRE) -- February 12, 2007 --Omega Navigation Enterprises, Inc. (NASDAQ: ONAV) (SGX: ONAV50), a provider of global marine transportation services focusing on product tankers, announced today that it has agreed to acquire two newbuilding Ice Class 1A Panamax product tankers. The vessels, which will be named the "Omega Emmanuel" and the "Omega Theodore" upon their delivery to the Company, each have a capacity of approximately 73,000 dwt. and are both currently under construction at STX Shipbuilding Co., South Korea.

The "Omega Emmanuel" is expected to be delivered on March 23, 2007 and the "Omega Theodore" is expected to be delivered on April 26, 2007. Following the delivery of these vessels, Omega Navigation will have a fleet of eight product carriers with a combined cargo carrying capacity of approximately 512,358 dwt. The Company also has options to acquire two additional double hull Ice Class 1A product carriers currently under construction which are expected to be available for delivery between August and September 2007.

The agreed purchase price of the "Omega Emmanuel" and the "Omega Theodore" is $64.5 million per vessel. The acquisitions will be funded with internally generated cash and commercial bank debt totaling $60 million per vessel. The balance will be funded by a $4.5 million, zero coupon warrant issued to the seller for each vessel, which will convert into Omega Class A common shares, no earlier than March 31, 2009.

The warrants will convert at a minimum price of $18 per share or at a price equal to the average market trading price during the 15 business days prior to the conversion date, less 8%, whichever is higher. The $18 per share conversion price represents a 16% premium to the closing price of the Company's Class A common shares, as of the market close Friday, February 09, 2007, and also a premium to the Company's IPO price of $17 per share.

The maximum number of shares to be issued to the warrant holders will be 250,000 Class A common shares per vessel. To the extent that the average market price during the 15 days preceding the conversion is below $18 per share, the Company has capped its downside exposure to a maximum amount of $500,000 per vessel, payable in cash, while maintaining an unlimited upside should the average trading price of the shares be above $18 per share. The warrants are non interest bearing, will not be entitled to dividends and have no voting rights. The Company's strategy will be to employ these vessels via fixed period charters, as is the case with the existing fleet, at a time when management believes the vessels' characteristics are fairly reflected in the time charter rates offered by the charterers.

George Kassiotis, President and CEO of Omega, commented: "The acquisition of these vessels is a continuation of the Company's commitment to the product tanker sector. The acquisition of this new type of vessel offers the Company access to the niche Panamax ice class market, which we believe has significant upside potential, while still offering maximum commercial flexibility. It solidifies our position in this market and our status as the only pure play product tanker company listed on a U.S. exchange. We also continue to implement our strategy of investing in modern, high quality assets, while at the same time increasing shareholder value."
