Omega Navigation Enterprises Announces Charters for the Two Recently Acquired Newbuildings, the "Omega Emmanuel" and "Omega Theodore"


PIRAEUS, GREECE -- (MARKET WIRE) -- March 6, 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 secured three year time charters at a daily rate of $25,500 for its two recently acquired newbuilding product tankers, the "Omega Emmanuel" and the "Omega Theodore," with ST Shipping & Transport Pte Ltd, a subsidiary of Glencore International AG.

Both time charters include profit sharing arrangements on quarterly basis, pursuant to which earnings from the vessels in excess of $25,500 per day will be divided equally between Omega Navigation and ST Shipping. This sharing ratio will be adjusted when the vessels trade in ice conditions, so that the profit sharing above the base rate of $25,500 per day between Omega Navigation and ST Shipping will be 65%/35%.

The three year charters on each vessel will commence after three voyages from delivery from the shipyard or after vetting approvals by two oil majors have been secured, whichever is earlier. During that period, the vessels will be employed by ST Shipping under a short-term time charter on the basis of commercial management. Omega Navigation has selected VShips as the vessels' technical manager.

The "Omega Emmanuel" and the "Omega Theodore" are two newbuilding Ice Class 1A panamax double hull product tankers, built by STX Shipbuilding Co., South Korea, each one with a capacity of 73,000 dwt. They are scheduled to be delivered to ST Shipping around March 23 and April 26, 2007, respectively, directly from the shipyard.

George Kassiotis, President and Chief Executive Officer of Omega Navigation, commented, "These two time charters are consistent with our strategy of seeking long term employment for our fleet at profitable rates and with first class charterers. This strategy enables us to generate strong and predictable cash flows and execute our consistent dividend distribution policy while at the same time be able to participate in the upside of the market through a profit sharing arrangement which to date has proven beneficial on our other vessels which have similar profit sharing arrangements.

"With these arrangements, our entire fleet of 8 product tankers is under fixed employment by which we have secured 100% of our operating days for 2007 and 2008. The charters on these newbuilding vessels extend to 2010.

"The time charters for the 'Omega Emmanuel' and the 'Omega Theodore' are expected to contribute to cash flow available for the payment of dividends approximately $.22 per share in 2007 and $.33 per share in 2008, based solely on the floor rate of $25,500 per day. Our profit sharing arrangements for these two vessels together with those for four of our other vessels, enable us to share in the market's upside potential with positive impact on our profitability."
