Pursuant to an Agreement and Plan of Merger dated December 5, 1996 among Energy
Ventures, Inc., a Delaware corporation ("EVI"), GulfMark Acquisition Co., a
Delaware corporation ("Sub"), GulfMark International, Inc., a Delaware
corporation ("GulfMark"), and GulfMark Offshore, Inc., upon the merger of Sub, a
wholly owned subsidiary of EVI, with and into GulfMark, each outstanding share
of GulfMark Common Stock was exchanged for .6693 shares of EVI Common Stock.



                                                                               6
Prior to the Merger, Holdings owned 1,015,113 shares of Common Stock of
GulfMark. As a result of the Merger on May 1, 1997, Holdings acquired 679,618
shares of the Common Stock of EVI.

Prior to the Merger, as a means of permitting EVI to acquire GulfMark, without
the marine transportation services business and all liabilities associated with
such assets, EVI, GulfMark and GulfMark Offshore, a wholly-owned subsidiary of
GulfMark, entered into a Agreement and Plan of Distribution dated as of December
5, 1996.
Pursuant to the Agreement and Plan of Distribution, the assets and certain other
GulfMark subsidiaries stock were contributed by GulfMark to GulfMark Offshore,
in consideration for the issuance by GulfMark Offshore to GulfMark of additional
shares of GulfMark Offshore Common Stock. As a result of this Spin-Off on April
30, 1997, GulfMark distributed to its stockholders all of the outstanding stock
of GulfMark Offshore on the basis of 2 shares of GulfMark Offshore for each
share of GulfMark Common Stock. As a result of the Distribution, Holdings
acquired 2,030,226 shares of the GulfMark Offshore and control of the company.

Holdings intends to continually evaluate EVI's business, prospects, financial
condition, the market for the Shares, other opportunities available to Holdings,
general economic conditions, money and stock market conditions and other factors
and future developments which Holdings may deem relevant from time to time.
Depending on same factors, Holdings may decide, subject to the below referenced
agreement, to sell all or part of the shares it holds. Any such acquisition or
disposition of Shares may be effected through open market or privately
negotiated transactions, or otherwise.

Except as set forth in this Item 4, Holdings does not have any specific plans or
proposals that relate to or would result in any of the actions specified in
clauses (a) through (j) of Item 4 of Schedule 13D.

In connection with the Distribution and Merger, Holdings agreed that it will not
for a period of one (1) year, sell, exchange, transfer by gift or otherwise
dispose, of any GulfMark Common Stock, GulfMark Offshore Common Stock or EVI
Common Stock received in the Merger.
