ATHENS, GREECE--(Marketwire - October 12, 2010) - Tsakos Energy Navigation Ltd. ("TEN") (NYSE: TNP) or (the "Company") today announced two-year charters with 50:50 profit share for two suezmaxes with charterers option for one additional year on one vessel and one twelve-month charter with 50:50 profit share for an ice- class aframax product tanker. These charters combined are expected to generate minimum gross revenues in excess of $44.0 million or $53.5 million if charterers exercise the one-year option on the one suezmax vessel. In addition to the recently announced three year fixture of a handysize product tanker, together with the employment of the other two aframax product tankers in the summer, the minimum gross revenue the company will expect to generate from its recent chartering activity should rise to $82.0 million.

The suezmax charters are in direct continuation from their previous fixtures with the same international oil major while the aframax was trading in the spot market. All three 1A ice-class aframaxes are chartered to a major North European shipping concern active in ice trades where the vessels are expected to operate. The vessels will earn a premium over the base rate for the duration of ice operations.

"We are pleased to continue implementing our tested chartering policy of term employment with upside potential to major international oil concerns. This allows us to both secure our bottom line and participate in market upturns in cooperation with our clients," Mr. Nikolas P. Tsakos, President & CEO of TEN stated. "The recent appetite of oil companies for term fixtures is a positive sign for the future particularly in a weak spot rate environment," Mr. Tsakos concluded.
