ITEM 2.  Acquisition or Disposition of Assets

         On May 28, 2001, and June 8, 2001, GulfMark obtained definitive
agreements to acquire all of the outstanding shares of Sea Truck Holding AS, a
privately- held Norwegian company ("Sea Truck"). Total consideration for the
acquisition is approximately $61.8 million which includes the assumption of debt
of approximately $23.2 million as of April 30, 2001. Approximately $18.4 million
of the purchase price will be funded through the Company's $75.0 million credit
facility. The balance of the purchase price will be funded by the Company's cash
on hand. Sea Truck owns five offshore support vessels which provide marine
support and transportation services to companies engaged in offshore exploration
and production of oil and gas in the North Sea. The closing of the acquisition
is subject to the termination of a prescribed notice period associated with a
corporate reorganization of Sea Truck that occurred prior to the acquisition.
The acquisition is expected to close on or about June 19, 2001.
