Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) On reviewing the Section 16 reporting requirements relating to GulfMark Offshore, Inc.'s Executive Nonqualified Excess Plan, it was determined that the phantom stock units created by the deferral of compensation by both officers and directors should have been reported as a derivative security by the officer/director once the phantom stock unit was allocated to his account. This filing reports all transactions related to the phantom stock units in the plan allocated to the individual from his point of entry into the plan through March 31, 2009. Each phantom stock unit is the economic equivalent of one share of common stock. Subject to the provisions of the plan, the phantom stock units become payable only in common stock upon the officer/director's termination of service."

Note: File three copies of this Form, one of which must be manually signed. If space provided is insufficient, see Instruction 6 for procedure.
