New Time Charter Agreements:

STEALTHGAS INC. announced that it has entered into a new bare boat charter arrangement for the "Gas Eternity," a new time charter arrangement for the "Gas Zael" and has extended the existing time charter for the "Gas Shanghai" with improved terms.

Upon the expiry of its current time charter on or about March 2007, the "Gas Eternity" will commence a three year bare boat charter at the rate of $122,500 per calendar month to a Far Eastern operator.

The "Gas Shanghai" has extended its existing time charter for a further six months from March 2007 at the improved rate of $225,000 per calendar month to an oil major.

Lastly, the "Gas Zael" has entered into a new time charter from January 30, 2007 with a major oil company for a period of between 45 and 60 days at a daily rate of $13,250 per day.

Update on Management Arrangements:

STEALTHGAS INC. also announced further details of the vessels being brought under the operational and technical management of its affiliated management company, Stealth Maritime Corp. Following today's delivery of the "Gas Flawless" which will be managed by Stealth Maritime Corp., the "Gas Cathar" and the "Gas Crystal" will also be brought under the technical and operational management of Stealth Maritime Corp. in early March 2007, bringing the total number of vessels managed by Stealth Maritime Corp. to eight.

CEO Harry Vafias commented, "We are very pleased to have taken delivery of the Gas Flawless, the first newbuilding acquired by STEALTHGAS and securing an attractive two year time charter upon her. We have also renewed the Gas Shanghai for an additional six months time charter at an improved rate and secured a three year bare boat charter on the Gas Eternity at a better net rate than she was earning previously whilst on a shorter period time charter. With these fixtures, we have further enhanced the earnings of the company while also extending the employment profile of the fleet with some 74% of voyage days now fixed for 2007, and 27% fixed for 2008. We are also pleased to have fixed the Gas Zael albeit for a relatively short time charter period at a very attractive rate.

Furthermore, we have been encouraged by the firming of employment rates in our sector over the past few weeks despite the relatively warm weather that has been affecting much of the world during the early part of the winter season. Finally, we believe that the continued implementation of our previously announced plan to bring vessels under the management of Stealth Maritime Corp. will also support positively the operational efficiency of the company going forward, and will enhance management efficiency by reducing the number of international third party managers utilized by the company."

Matters discussed in this release may constitute forward-looking statements. Forward-looking statements reflect our current views with respect to future events and financial performance and may include statements concerning plans, objectives, goals, strategies, future events or performance, and underlying assumptions and other statements, which are other than statements of historical facts. The forward-looking statements in this release are based upon various assumptions, many of which are based, in turn, upon further assumptions, including without limitation, management's examination of historical operating trends, data contained in our records and other data available from third parties. Although STEALTHGAS INC. believes that these assumptions were reasonable when made, because these assumptions are inherently subject to significant uncertainties and contingencies which are difficult or impossible to predict and are beyond our control, STEALTHGAS INC. cannot assure you that it will achieve or accomplish these expectations, beliefs or projections. Important factors that, in our view, could cause actual results to differ materially from those discussed in the forward-looking statements include the strength of world economies and currencies, general market conditions, including changes in charterhire rates and vessel values, changes in demand that may affect attitudes of time charterers to scheduled and unscheduled drydocking, changes in STEALTHGAS INC.'s operating expenses, including bunker prices, dry-docking and insurance costs, or actions taken by regulatory authorities, potential liability from pending or future litigation, domestic and international political conditions, potential disruption of shipping routes due to accidents and political events or acts by terrorists.

Risks and uncertainties are further described in reports filed by STEALTHGAS INC. with the US Securities and Exchange Commission.
