HOS Closes Sea Mar Fleet Acquisition

Hornbeck Offshore Services completed its acquisition of 20 offshore supply vessels and their related business from certain affiliates of Nabors Industries Ltd. for $186 million, plus the cost of the fuel inventory on the vessels. The Sea Mar Fleet is comprised of ten 200 class DP-1 new generation OSVs and ten conventional OSVs.

The company also acquired one 285-foot DP-2 new generation OSV currently under construction at a domestic shipyard with an anticipated fourth quarter 2008 delivery. The total estimated cost of this newbuild vessel, prior to allocation of construction period interest, is approximately $34.0 million, of which $7.3 million was paid to Nabors at closing. All of the vessels acquired by Hornbeck Offshore are U.S. flagged and qualify for U.S. coastwise trade under the "Jones Act" except for one of the conventional vessels, which is foreign-flagged. In addition, Hornbeck Offshore now manages five Nabors-owned Mexican flagged vessels currently operating offshore Mexico.
