GulfMark Offshore Exercises Option to Build Second Aker Vessel

GulfMark Offshore, Inc. reports that it has exercised an option to build a second Aker PSV09 design vessel.

This vessel, which will be an identical sister ship to the Aker PSV09 currently under construction in Norway, is a 4,850 deadweight ton, diesel electric powered platform supply vessel. The purchase price for this vessel is approximately $30 million, with delivery currently expected during the third quarter of 2007. GulfMark will be the majority investor in a joint venture for the construction of the vessel. GulfMark has elected to purchase 100% of the first Aker PSV09 and has the right to purchase this vessel upon pre-agreed terms.

Bruce Streeter, President and Chief Operating Officer of the Company, commented: ``This decision to build the second Aker 09 vessel confirms and completes our new construction program. We have reviewed the market conditions and opportunities and believe that the addition of this high specification, highly efficient vessel is an excellent fit with the expectations of our customers. While GulfMark will continue to be opportunistic, we have now put together the additions to the fleet that we feel appropriate from both a strategic and earnings growth perspective. The addition of this vessel, coupled with the other vessels previously announced, should result in a substantial growth in earnings and cash flow. These additions are long lived assets that will start providing cash benefits in 2006, and like the building program started in calendar year 2000, will add significantly to the company's overall fleet value.''

Including this vessel, the Company currently has ten owned vessels under construction bringing the fleet of owned vessels to 58 in 2008 when the last vessel is delivered. Without additional changes, at the conclusion of this expansion the fleet would be comprised of 58 owned and 10 managed vessels.
