Tsakos Energy Navigation announces time charters for suezmax tankers Decathlon and Archangel

Charters to generate at least $17.5 million in gross revenues

ATHENS, GREECE – September 30, 2009 - Tsakos Energy Navigation Limited (“TEN” or the “Company”) (NYSE:TNP) today announced a two year time-charter extension with profit sharing up to a maximum level with the same charterer, for the 2002-built double hull suezmax tanker Decathlon. TEN also announced a three-to-six month time charter for the 2006-built suezmax tanker Archangel through the initiation of a relationship with an international oil major. Prior to this new charter, the Archangel was operating in the spot market.

Assuming the minimum rate on the Decathlon and the minimum duration on the Archangel the charters should generate gross revenues in excess of $17.5 million. Should the Archangel charterer exercise its option for an additional 90 days, the total gross revenues could grow by another $2.5 million, providing up to $20 million in cash flow contribution.

Following this charter extension, TEN’s fixed employment, including pool vessels, for remainder of 2009 and 2010 operating days is revised upward to 67% and 52%, respectively.

“TEN continues to extend its charter coverage with first class, long-term clients and by initiating new business relationships with major oil companies,” said Mr. Nikolas P. Tsakos, President and CEO of TEN. “TEN remains committed to its balanced employment policy to safeguard revenues to allow the Company to meet its growth plans.”
